  • The objective of this research is to test the feasibility of developing a statewide truck traffic forecasting methodology for Wisconsin by using Origin-Destination surveys, traffic counts, classification counts, and other data that are routinely collected by the Wisconsin Department of Transportation (WisDOT). Development of a feasible model will permit estimation of future truck traffic for every major link in the network. This will provide the basis for improved estimation of future pavement deterioration. Pavement damage rises exponentially as axle weight increases, and trucks are responsible for most of the traffic-induced damage to pavement. Consequently, forecasts of truck traffic are critical to pavement management systems. The pavement Management Decision Supporting System (PMDSS) prepared by WisDOT in May 1990 combines pavement inventory and performance data with a knowledge base consisting of rules for evaluation, problem identification and rehabilitation recommendation. Without a r.easonable truck traffic forecasting methodology, PMDSS is not able to project pavement performance trends in order to make assessment and recommendations in the future years. However, none of WisDOT's existing forecasting methodologies has been designed specifically for predicting truck movements on a statewide highway network. For this research, the Origin-Destination survey data avaiiable from WisDOT, including two stateline areas, one county, and five cities, are analyzed and the zone-to'||'&'||'not;zone truck trip tables are developed. The resulting Origin-Destination Trip Length Frequency (00 TLF) distributions by trip type are applied to the Gravity Model (GM) for comparison with comparable TLFs from the GM. The gravity model is calibrated to obtain friction factor curves for the three trip types, Internal-Internal (I-I), Internal-External (I-E), and External-External (E-E). ~oth "macro-scale" calibration and "micro-scale" calibration are performed. The comparison of the statewide GM TLF with the 00 TLF for the macro-scale calibration does not provide suitable results because the available 00 survey data do not represent an unbiased sample of statewide truck trips. For the "micro-scale" calibration, "partial" GM trip tables that correspond to the 00 survey trip tables are extracted from the full statewide GM trip table. These "partial" GM trip tables are then merged and a partial GM TLF is created. The GM friction factor curves are adjusted until the partial GM TLF matches the 00 TLF. Three friction factor curves, one for each trip type, resulting from the micro-scale calibration produce a reasonable GM truck trip model. A key methodological issue for GM. calibration involves the use of multiple friction factor curves versus a single friction factor curve for each trip type in order to estimate truck trips with reasonable accuracy. A single friction factor curve for each of the three trip types was found to reproduce the 00 TLFs from the calibration data base. Given the very limited trip generation data available for this research, additional refinement of the gravity model using multiple mction factor curves for each trip type was not warranted. In the traditional urban transportation planning studies, the zonal trip productions and attractions and region-wide OD TLFs are available. However, for this research, the information available for the development .of the GM model is limited to Ground Counts (GC) and a limited set ofOD TLFs. The GM is calibrated using the limited OD data, but the OD data are not adequate to obtain good estimates of truck trip productions and attractions .. Consequently, zonal productions and attractions are estimated using zonal population as a first approximation. Then, Selected Link based (SELINK) analyses are used to adjust the productions and attractions and possibly recalibrate the GM. The SELINK adjustment process involves identifying the origins and destinations of all truck trips that are assigned to a specified "selected link" as the result of a standard traffic assignment. A link adjustment factor is computed as the ratio of the actual volume for the link (ground count) to the total assigned volume. This link adjustment factor is then applied to all of the origin and destination zones of the trips using that "selected link". Selected link based analyses are conducted by using both 16 selected links and 32 selected links. The result of SELINK analysis by u~ing 32 selected links provides the least %RMSE in the screenline volume analysis. In addition, the stability of the GM truck estimating model is preserved by using 32 selected links with three SELINK adjustments, that is, the GM remains calibrated despite substantial changes in the input productions and attractions. The coverage of zones provided by 32 selected links is satisfactory. Increasing the number of repetitions beyond four is not reasonable because the stability of GM model in reproducing the OD TLF reaches its limits. The total volume of truck traffic captured by 32 selected links is 107% of total trip productions. But more importantly, ~ELINK adjustment factors for all of the zones can be computed. Evaluation of the travel demand model resulting from the SELINK adjustments is conducted by using screenline volume analysis, functional class and route specific volume analysis, area specific volume analysis, production and attraction analysis, and Vehicle Miles of Travel (VMT) analysis. Screenline volume analysis by using four screenlines with 28 check points are used for evaluation of the adequacy of the overall model. The total trucks crossing the screenlines are compared to the ground count totals. L V/GC ratios of 0.958 by using 32 selected links and 1.001 by using 16 selected links are obtained. The %RM:SE for the four screenlines is inversely proportional to the average ground count totals by screenline .. The magnitude of %RM:SE for the four screenlines resulting from the fourth and last GM run by using 32 and 16 selected links is 22% and 31 % respectively. These results are similar to the overall %RMSE achieved for the 32 and 16 selected links themselves of 19% and 33% respectively. This implies that the SELINICanalysis results are reasonable for all sections of the state.Functional class and route specific volume analysis is possible by using the available 154 classification count check points. The truck traffic crossing the Interstate highways (ISH) with 37 check points, the US highways (USH) with 50 check points, and the State highways (STH) with 67 check points is compared to the actual ground count totals. The magnitude of the overall link volume to ground count ratio by route does not provide any specific pattern of over or underestimate. However, the %R11SE for the ISH shows the least value while that for the STH shows the largest value. This pattern is consistent with the screenline analysis and the overall relationship between %RMSE and ground count volume groups. Area specific volume analysis provides another broad statewide measure of the performance of the overall model. The truck traffic in the North area with 26 check points, the West area with 36 check points, the East area with 29 check points, and the South area with 64 check points are compared to the actual ground count totals. The four areas show similar results. No specific patterns in the L V/GC ratio by area are found. In addition, the %RMSE is computed for each of the four areas. The %RMSEs for the North, West, East, and South areas are 92%, 49%, 27%, and 35% respectively, whereas, the average ground counts are 481, 1383, 1532, and 3154 respectively. As for the screenline and volume range analyses, the %RMSE is inversely related to average link volume. 'The SELINK adjustments of productions and attractions resulted in a very substantial reduction in the total in-state zonal productions and attractions. The initial in-state zonal trip generation model can now be revised with a new trip production's trip rate (total adjusted productions/total population) and a new trip attraction's trip rate. Revised zonal production and attraction adjustment factors can then be developed that only reflect the impact of the SELINK adjustments that cause mcreases or , decreases from the revised zonal estimate of productions and attractions. Analysis of the revised production adjustment factors is conducted by plotting the factors on the state map. The east area of the state including the counties of Brown, Outagamie, Shawano, Wmnebago, Fond du Lac, Marathon shows comparatively large values of the revised adjustment factors. Overall, both small and large values of the revised adjustment factors are scattered around Wisconsin. This suggests that more independent variables beyond just 226; population are needed for the development of the heavy truck trip generation model. More independent variables including zonal employment data (office employees and manufacturing employees) by industry type, zonal private trucks 226; owned and zonal income data which are not available currently should be considered. A plot of frequency distribution of the in-state zones as a function of the revised production and attraction adjustment factors shows the overall " adjustment resulting from the SELINK analysis process. Overall, the revised SELINK adjustments show that the productions for many zones are reduced by, a factor of 0.5 to 0.8 while the productions for ~ relatively few zones are increased by factors from 1.1 to 4 with most of the factors in the 3.0 range. No obvious explanation for the frequency distribution could be found. The revised SELINK adjustments overall appear to be reasonable. The heavy truck VMT analysis is conducted by comparing the 1990 heavy truck VMT that is forecasted by the GM truck forecasting model, 2.975 billions, with the WisDOT computed data. This gives an estimate that is 18.3% less than the WisDOT computation of 3.642 billions of VMT. The WisDOT estimates are based on the sampling the link volumes for USH, 8TH, and CTH. This implies potential error in sampling the average link volume. The WisDOT estimate of heavy truck VMT cannot be tabulated by the three trip types, I-I, I-E ('||'&'||'pound;-I), and E-E. In contrast, the GM forecasting model shows that the proportion ofE-E VMT out of total VMT is 21.24%. In addition, tabulation of heavy truck VMT by route functional class shows that the proportion of truck traffic traversing the freeways and expressways is 76.5%. Only 14.1% of total freeway truck traffic is I-I trips, while 80% of total collector truck traffic is I-I trips. This implies that freeways are traversed mainly by I-E and E-E truck traffic while collectors are used mainly by I-I truck traffic. Other tabulations such as average heavy truck speed by trip type, average travel distance by trip type and the VMT distribution by trip type, route functional class and travel speed are useful information for highway planners to understand the characteristics of statewide heavy truck trip patternS. Heavy truck volumes for the target year 2010 are forecasted by using the GM truck forecasting model. Four scenarios are used. Fo~ better forecasting, ground count- based segment adjustment factors are developed and applied. ISH 90 '||'&'||' 94 and USH 41 are used as example routes. The forecasting results by using the ground count-based segment adjustment factors are satisfactory for long range planning purposes, but additional ground counts would be useful for USH 41. Sensitivity analysis provides estimates of the impacts of the alternative growth rates including information about changes in the trip types using key routes. The network'||'&'||'not;based GMcan easily model scenarios with different rates of growth in rural versus . . urban areas, small versus large cities, and in-state zones versus external stations. cities, and in-state zones versus external stations.

  • 본 연구는 Rapid Upper Limb Assessment(RULA)를 이용하여 자동차 조립작 업에 대한 인간공학적 작업평가를 하고, 이 결과와 작업관련 상지 근골격계 질환의 자각증상율 및 작업특성 변수들의 연관성을 분석함으로써, RULA결과가 관련 신체부위의 통증이나 불편함으로 보고되는 근골격계 부하의 좋은 지표가 될 수 있는지, RULA평가체계를 이용하여 작업 위험도가 적합한지 여부를 평가할 수 있는가를 보고자 하였다. 자동차 제조업 작업자 314명을 대상으로 근골격계질환 자각증상설문과 RULA를 이용한 작업평가를 하였으며, 다음과 같은 결과를 얻었다. 1. NIOSH의 작업관련 근골격계 질환의 감시기준(surveillence criteria)에 따라 자각증상을 조사한 결과, 연구대상자 중 목 32.8%, 어깨 26.4%, 팔 10.5%, 손 29.3%, 허리 41.4%였으며, 한가지 이상 의 증상을 보이는 경우는 62.4%의 분포를 보였다. 2. 품질관리부에 비해 조립부서 작업자 틀이 전체 증상과 어깨, 허리, 팔 및 손부 위 증상에서 더 높은 유증상률을 보였다(p<0.05). 3. 부서별 RULA를 이용한 작업평가 결과, 서브/조립반과 의장반의 공정이 높은 위험점수를 보였다. 전체 조립부서에 대한 평가결과 적합한 작업은 3.02%였고, 62.8%가 부적합한 작업으로 작업전환이나 중재조치가 필요한 경우였다. 자각증상과 RULA를 이용한 작업평가 결과를 비교한 결과 RULA점수가 클수록 자각증상율이 높음을 보였다.(p<0.05) 4. RULA평가지표와 자각증상사이의 관련성을 보기 위하여, RULA지표와 기타 작업관련요인들을 독립변수로, 자각증상유무를 종속변수로 하여 다중 로지스틱 회귀분석을 실시하였다. 최종적으로 증상유무를 가장 잘 설명하는 회귀모형에 대한 분석결과는 다음과 같다. 모든 증상군에 대해서는 반복작업(OR 2.183), 진동공구 사용(OR 2.775)과 총 위험도 점수(OR 2.250); 목 부위 증상군에서는 상완의 자세점수(OR 1.786), 상완 및 손부 위의 총점수(OR 1.634) ; 어깨 증상군은 상지의 근사용(OR 3.076), 상완 및 손부 위의 총점수(OR 1.798); 어깨와 목 부위를 합한 증상군은 상완 및 손부위의 총점 수(OR 1.715)와 상지의 근사용 점수(OR 2.057); 팔 증상군에서는 상지의 근사용 점수(OR 10.662) ; 손 부위 증상군에 대해서는 손목의 자세/손목 비틀림 지표 (OR 2.068)와 상지의 근사용 점수(OR 2.215); 허리부위 증상군에서는 하지의 근사용 점수(OR 2.601)가 통계적으로 유의한 지표였다.(p<0.05) 이상의 결과에서 작업관련 상지근골격계 자각증상과 RULA 점수사이에는 연관성이 있음이 관찰되었다. 이는 RULA가 직업성 질환을 유발할 수 있는 근골격계 부하에 폭로된 작업자들을 평가하는, 일차적인 작업 위험도 평가도구(Screening tool)로서 쓰일 수 있음을 말해준다. 다만 향후 RULA 사용에 있어서 상지(upper limb)와 허리부위(back)의 평가를 구분하고, 기타 다른 작업관련 요인들에 대한 평가체계를 보완하는 것이 필요하다.

  • Due to the increasing and intensifying competition in the Internet shopping market, it has been recognized as very important to develop an effective policy and strategy for acquiring loyal customers. For this reason, web site designers need to know if a new Internet shopping mall(ISM) will be accepted. Researchers have been working on identifying factors for explaining and predicting user acceptance of an ISM. Some studies, however, revealed inconsistent findings on the antecedents of user acceptance of a website. Lack of consideration for individual differences in user ability is believed to be one of the key reasons for the mixed findings. The elaboration likelihood model (ELM) and several studies have suggested that individual differences in ability plays an moderating role on the relationship between the antecedents and user acceptance. Despite the critical role of user ability, little research has examined the role of user ability in the Internet shopping mall context. The purpose of this study is to develop a user acceptance model that consider the moderating role of user ability in the context of Internet shopping. This study was initiated to see the ability of the technology acceptance model(TAM) to explain the acceptance of a specific ISM. According to TAM. which is one of the most influential models for explaining user acceptance of IT, an intention to use IT is determined by usefulness and ease of use. Given that interaction between user and website takes place through web interface, the decisions to accept and continue using an ISM depend on these beliefs. However, TAM neglects to consider the fact that many users would not stick to an ISM until they trust it although they may think it useful and easy to use. The importance of trust for user acceptance of ISM has been raised by the relational views. The relational view emphasizes the trust-building process between the user and ISM, and user's trust on the website is a major determinant of user acceptance. The proposed model extends and integrates the TAM and relational views on user acceptance of ISM by incorporating usefulness, ease of use, and trust. User acceptance is defined as a user's intention to reuse a specific ISM. And user ability is introduced into the model as moderating variable. Here, the user ability is defined as a degree of experiences, knowledge and skills regarding Internet shopping sites. The research model proposes that the ease of use, usefulness and trust of ISM are key determinants of user acceptance. In addition, this paper hypothesizes that the effects of the antecedents(i.e., ease of use, usefulness, and trust) on user acceptance may differ among users. In particular, this paper proposes a moderating effect of a user's ability on the relationship between antecedents with user's intention to reuse. The research model with eleven hypotheses was derived and tested through a survey that involved 470 university students. For each research variable, this paper used measurement items recognized for reliability and widely used in previous research. We slightly modified some items proper to the research context. The reliability and validity of the research variables were tested using the Crobnach's alpha and internal consistency reliability (ICR) values, standard factor loadings of the confirmative factor analysis, and average variance extracted (AVE) values. A LISREL method was used to test the suitability of the research model and its relating six hypotheses. Key findings of the results are summarized in the following. First, TAM's two constructs, ease of use and usefulness directly affect user acceptance. In addition, ease of use indirectly influences user acceptance by affecting trust. This implies that users tend to trust a shopping site and visit repeatedly when they perceive a specific ISM easy to use. Accordingly, designing a shopping site that allows users to navigate with heuristic and minimal clicks for finding information and products within the site is important for improving the site's trust and acceptance. Usefulness, however, was not found to influence trust. Second, among the three belief constructs(ease of use, usefulness, and trust), trust was empirically supported as the most important determinants of user acceptance. This implies that users require trustworthiness from an Internet shopping site to be repeat visitors of an ISM. Providing a sense of safety and eliminating the anxiety of online shoppers in relation to privacy, security, delivery, and product returns are critically important conditions for acquiring repeat visitors. Hence, in addition to usefulness and ease of use as in TAM, trust should be a fundamental determinants of user acceptance in the context of internet shopping. Third, the user's ability on using an Internet shopping site played a moderating role. For users with low ability, ease of use was found to be a more important factors in deciding to reuse the shopping mall, whereas usefulness and trust had more effects on users with high ability. Applying the EML theory to these findings, we can suggest that experienced and knowledgeable ISM users tend to elaborate on such usefulness aspects as efficient and effective shopping performance and trust factors as ability, benevolence, integrity, and predictability of a shopping site before they become repeat visitors of the site. In contrast, novice users tend to rely on the low elaborating features, such as the perceived ease of use. The existence of moderating effects suggests the fact that different individuals evaluate an ISM from different perspectives. The expert users are more interested in the outcome of the visit(usefulness) and trustworthiness(trust) than those novice visitors. The latter evaluate the ISM in a more superficial manner focusing on the novelty of the site and on other instrumental beliefs(ease of use). This is consistent with the insights proposed by the Heuristic-Systematic model. According to the Heuristic-Systematic model. a users act on the principle of minimum effort. Thus, the user considers an ISM heuristically, focusing on those aspects that are easy to process and evaluate(ease of use). When the user has sufficient experience and skills, the user will change to systematic processing, where they will evaluate more complex aspects of the site(its usefulness and trustworthiness). This implies that an ISM has to provide a minimum level of ease of use to make it possible for a user to evaluate its usefulness and trustworthiness. Ease of use is a necessary but not sufficient condition for the acceptance and use of an ISM. Overall, the empirical results generally support the proposed model and identify the moderating effect of the effects of user ability. More detailed interpretations and implications of the findings are discussed. The limitations of this study are also discussed to provide directions for future research.

  • In view of ever rising water pollution problems of river in the vicinity of large urban communities, the author has made an investigation on the pollution of water sampled from Han River (Seoul area) and Nakdong River (Daegu city area) during the period from July to December, 1970. The water samples were taken twice a month during the study period of 6 months from 7 points (locations) along the main stream of Han River at Seoul city and 5 points of Nakdong River at Daegu city. The samples ware measured and analyzed in accordance with the recognized methods in the 'Standard Methods for Examination of Water and waste' by American Public Health Association. The obtained results are as follows : I. Han River. 1. Average turbidity was 5.1 units ranging from 1 to 10 units and the turbidity of down stream was higher than that of the upper stream. 2. pH value showed slight alkalinity (mean;7.2) except Yunchang-Dong (6.9). 3. The mean value of Dissolved Oxygen contents (D.O) was 7.2 ppm. (range of 3.4-10.5ppm.). D.O. of the upper stream (8.2 ppm. at Walker Hill boating place, 8.0 ppm. at the Gwangzang Bridge and Ddookdo) was higher than that of he downstream (5.6ppm. at Yumchang-Dong, 6.4 ppm. at the 2nd Han River Bridge), and D.O. in the winter season was higher than that in the summer season, respectively. 4 The mean value of the Biochemical Oxygen Demand (B.O.D.) was 28.3 ppm. (range of 6.2-64.8 ppm.). The mean value of B.O.D. was 48.7 ppm. at Yumchang-Dong, 42.3 ppm. at the 2nd Han River Bridge, 34.0 ppm. at the 1st nan River Bridge, 28.5 ppm. at the 3rd Han River Bridge, 19.2 ppm. at Dookdo, 13.2 ppm. at the Gwangzang Bridge, and 10.2 ppm. at the Walker Hill boating place in order of value. B.O.D. in July and August (35.6 and 34.5 ppm.) were the highest and that in November and December (18.6 and 21.2 ppm.) were the lowest. 5. Suspended Solids (SS) were from 15.0 to 667.0 ppm. with the mean of 222.1 ppm. 'Suspended Solids' of the water samples at Yumchang-Dong and the 2nd Han River Bridge were found to be 378.1 ppm. and 283.9 ppm. respectively which were higher than at the Gwangzang Bridge (134.1 ppm.) and at Walker Hill boating place (79.3ppm.). 6. Coliform colonies counting of the water samples ranged from $0-2,500{\times}10/100ml$. with the mean value of $205.6{\times}10/100ml$. The most contaminated water sample by coliform were from the point of the 2nd Han River Bridge with $640.8{\times}10/100ml$ while the lowest ones were from Walker Hill boating place with $17.2{\times}10/100ml$. There was also a seasonal variation in coliform contamination that is the higher in summer and the lower in winter. II. Nakdong River 1. The mean value of turbidity was 2.3 units with range of 0 to 9.0 units. The highest point was at Geumho River (7.2 units). and the lowest point was at Gangzung and Moonsan (0.45 and 0.41 units). 2. The mean value of pH was 7.5 (range of 7.1-8.5) and highest point was Geumho River with 8.5. 3. The mean value of D.O. was 8.1 ppm. (range of 3.4-11.2 ppm.). D.O. of the upper stream showed higher value than that of the down stream, and the winter season than the summer season. 4. B.O.D. ranged from 2.6 to 57.0 ppm. (mean; 20.4ppm.). The water sample at Geumho River showed the highest value (41.5 ppm.) while at Moonsan and Gangzung showed the lowest (4.6 and 4.7 ppm.). 5. The mean value of suspended solids was 48.7 ppm. (range of 4.0-182.0 ppm.). The highest month was July (63.7ppm.) and August (62.1 ppm.) and the lowest month was October (37.0 ppm.) and December (24.4 ppm.). 6. The mean value of the coliform colonies was $22.7{\times}10/100ml$. (range of $0-243{\times}10/100ml$.). The highest number of the colonies was found in the sample water at the Whawon recreation area ($50.5{\times}10/100ml$.) followed by the Geumho River ($33.9{\times}10/100ml$.), the Goryung Bridge ($28.3{\times}10/100ml$.), Gangzung($0.7{\times}10/100ml$), and Moonsan ($0.6{\times}10/100ml$.).

  • 본 연구에서 조사된 일부 선도적인 양돈농가에서는 설치 운영하는 호기적 액상발효 공정은 대부분의 농가가 공정별 설계인자 및 물리 화학적인 성분변화의 특성보다는 경험적인 운영을 토대로 액비를 생산하고 있는 것을 알 수 있었다. 김 등의 조사연구에 따르면 가축분뇨의 발생단계인 분뇨수거방식은 현재 국내 돈사의 70% 이상이 슬러리 형태로 분뇨가 배출되고 있는 것으로 보고되고 있다. 양돈분뇨의 수거방식과 배출형태가 대부분 슬러리라는 사실은 양돈분뇨의 적정처리에 의한 환경오염 차단과 자원화 이용과정에 적용될 각종 공법 및 시스템 적용이 돈사 슬러리부터 집중 관리해야 함을 시사한다. 이처럼 가축분뇨 액비화의 적정처리에 있어서는 발생단계 뿐만 아니라 액비가 토양에 환원되기 직전까지의 모든 과정이 전반적으로 고려되어야 한다. 본 연구의 조사대상 농가의 가축분뇨 액비화 운영에 있어서 핵심적으로 구분 할 수 있는 단계를 주요사항 별로 구분하여 Table 8에 나타내었다. 가축분뇨 액비화 처리에 있어서 고액분리 단계의 경우 고액분리 방식과 효율에 따라 BOD (생물학적산소요구량), COD (화학적산소요구량), VFA (휘발성지방산) 등의 제거율의 차이가 있는 것으로 보고되고 있으며, 이는 후단공정 즉 주발효조에서의 공기주입량의 산정, 공기공급방식, 발효기간 및 2차 발효 등 운영방식 결정에 주요한 요인이 될 수 있다. 이와 같이 액비가 생산되어 토양에 환원되기까지의 과정은 각각의 주요한 요소들이 유기적으로 연계되어 있으며, 농가 현장을 방문조사하고, 생산되는 액비를 비교 분석한 결과 액비화 공정에 있어서 필수적인 핵심적 단계를 도출 할 수 있었다. 이에 대한 주요내용은 다음과 같다. 1. 돈사 슬러리 관리 단계 돈사 슬러리는 혐기부패를 최대한 방지하며, 주요 악취물질인 $H_2S$, $NH_4$, VFAs의 생성을 억제하여야 한다. 돈사환경을 개선하기 위한 방법으로서는 부숙이 완전히 완료되어 유용미생물이 활성화된 액비를 돈사 세척수로 이용하거나, 슬러리 피트에 일부 투입하여 단순 저장일수를 처리일수로의 개념적 전환이 필요하다. 2. 고액분리 단계 일반적으로 BOD의 주요원인인 고농도의 유기물질은 대부분 분뇨의 고형성분에 포함되어 있기 때문에 물리적 처리공정인 고액분리 단계에서 최대한으로 제거하여 후단공정인 주발효조의 부하를 최소화 시킨다. 3. 발효처리-공기공급 단계 축산농가 마다 사료의 종류나 관리방법 등이 각기 다르므로 배출되는 슬러리의 성상을 파악하여 물질수지와 처리일수에 기초한 발효조 용량과 공기주입량의 산정이 필요하다. 또한 공기확산 및 막힘현상을 고려한 자동제어 장치나 발효조의 상태를 감시 제어하기 위한 인자로서 pH 및 산화환원전위 등을 실시간으로 모니터링 하는 것이 중요하다. 4. 발효처리-미생물, 반송 단계 일반점검 (온도, pH, 용존산소, 산화환원전위, 전기전도도 등)과 정밀점검 (BOD, COD, VFAs, SS, N, P 등)의 주기적인 점검을 통하여 미생물 생장에 알맞은 유입농도와 반송량을 결정하고 농가환경에 맞는 발효조 운전방식을 확립 할 필요가 있다. 5. 후숙처리-최종액비 단계 후숙조에서는 공기과잉 투입으로 인한 질소성분의 손실을 방지하고, 유용미생물을 이용하여 토양환원에 적합한 액비를 제조한다. 가스발생에 의한 작물생육 피해를 방지할 수 있는 액비 안정화 운전기술을 확립하고, 살포시기를 대응하여 액비의 유 출입을 집중적으로 관리한다. 6. 액비유통센터 연계-농지환원 단계 제조된 액비는 액비유통센터에 위탁하여 살포하는 체계를 확립하고, 악취 민원의 발생을 최대한 억제한다. 액비유통센터는 철저한 년 중 살포프로그램을 운영하여 원활한 살포조직 체제를 구성하는 것이 중요하다. 축산농가에서 가축분뇨 관리방법은 축사의 입지, 주변 환경 및 각종 환경규제 등 여러가지 여건에 따라 각기 다르며, 다수의 축산농가가 특정한 처리방법을 동일하게 적용하는 것은 현실적으로 불가능하다. 따라서 본 연구에서 분석된 각 농가의 액비 성상 등은 여러 가지 환경적 요소가 복합적으로 작용하고 있으며, 조사농가 중 일부는 발효과정 중에 있는 액비를 채취하였으므로, 분석결과를 해석하여 가축분뇨 운영관리를 총체적으로 판단하는 것은 다소 무리가 있다. 추후에는 각 공정에 대해 유입되는 슬러리원수에서부터 처리가 완료되는 단계까지의 과정을 일괄적으로 분석하여, 유입 유출농도, 수리학적 체류시간 등 공학적 요소 및 이에 따른 경제성 평가 등을 세밀하게 연구할 필요성이 있다. 이밖에도 가축분뇨의 중요한 관리부분인 병원성미생물과 관련된 위해성 분분을 고려하지 않을 수 없다. 가축분뇨에는 인간에게 직접적인 영향을 미칠 수 있는 Escherichia coli, Campylobacter, salmonella, Listeria 등 다양한 병원성 세균이 발견된다. 최근 전국적으로 발생된 구제역 사태는 우리나라 축산업 자체에 큰 타격을 주었을 뿐만 아니라, 사회 경제적으로도 막대한 손실을 가져왔다. 이 사건을 계기로 국내 축산기반의 전면적 재정비가 불가피하게 되었음은 물론 가축 분뇨에서 유래한 병원성 미생물 및 바이러스 등의 근원적 대처방법 개선과 가축분뇨의 위생적 처리에 대한 안전관리가 시급한 현안이 되었다. 따라서 안전한 경축순환의 액비유통 관리 체계 구축을 위해서는 병원성 미생물, 바이러스 등과 같은 위해요소를 억제 할 수 있는 액비화 처리기술의 표준화 공정 개발 또한 필요하다.

  • Much has teed changed in the field of hospital administration in the It wake of the rapid development of sciences, techniques ana systematic hospital management. However, we still have a long way to go in organization, in the quality of hospital employees and hospital equipment and facilities, and in financial support in order to achieve proper hospital management. The above factors greatly effect the ability of hospitals to fulfill their obligation in patient care and nursing services. The purpose of this study is to determine the optimal methods of standardization and quality nursing so as to improve present nursing services through investigations and analyses of various problems concerning nursing administration. This study has been undertaken during the six month period from October 1971 to March 1972. The 41 comprehensive hospitals have been selected iron amongst the 139 in the whole country. These have been categorized according-to the specific purposes of their establishment, such as 7 university hospitals, 18 national or public hospitals, 12 religious hospitals and 4 enterprise ones. The following conclusions have been acquired thus far from information obtained through interviews with nursing directors who are in charge of the nursing administration in each hospital, and further investigations concerning the purposes of establishment, the organization, personnel arrangements, working conditions, practices of service, and budgets of the nursing service department. 1. The nursing administration along with its activities in this country has been uncritical1y adopted from that of the developed countries. It is necessary for us to re-establish a new medical and nursing system which is adequate for our social environments through continuous study and research. 2. The survey shows that the 7 university hospitals were chiefly concerned with education, medical care and research; the 18 national or public hospitals with medical care, public health and charity work; the 2 religious hospitals with medical care, charity and missionary works; and the 4 enterprise hospitals with public health, medical care and charity works. In general, the main purposes of the hospitals were those of charity organizations in the pursuit of medical care, education and public benefits. 3. The survey shows that in general hospital facilities rate 64 per cent and medical care 60 per-cent against a 100 per cent optimum basis in accordance with the medical treatment law and approved criteria for training hospitals. In these respects, university hospitals have achieved the highest standards, followed by religious ones, enterprise ones, and national or public ones in that order. 4. The ages of nursing directors range from 30 to 50. The level of education achieved by most of the directors is that of graduation from a nursing technical high school and a three year nursing junior college; a very few have graduated from college or have taken graduate courses. 5. As for the career tenure of nurses in the hospitals: one-third of the nurses, or 38 per cent, have worked less than one year; those in the category of one year to two represent 24 pet cent. This means that a total of 62 per cent of the career nurses have been practicing their profession for less than two years. Career nurses with over 5 years experience number only 16 per cent: therefore the efficiency of nursing services has been rated very low. 6. As for the standard of education of the nurses: 62 per cent of them have taken a three year course of nursing in junior colleges, and 22 per cent in nursing technical high schools. College graduate nurses come up to only 15 per cent; and those with graduate course only 0.4 per cent. This indicates that most of the nurses are front nursing technical high schools and three year nursing junior colleges. Accordingly, it is advisable that nursing services be divided according to their functions, such as professional, technical nurses and nurse's aides. 7. The survey also shows that the purpose of nursing service administration in the hospitals has been regulated in writing in 74 per cent of the hospitals and not regulated in writing in 26 per cent of the hospitals. The general purposes of nursing are as follows: patient care, assistance in medical care and education. The main purpose of these nursing services is to establish proper operational and personnel management which focus on in-service education. 8. The nursing service departments belong to the medical departments in almost 60 per cent of the hospitals. Even though the nursing service department is formally separated, about 24 per cent of the hospitals regard it as a functional unit in the medical department. Only 5 per cent of the hospitals keep the department as a separate one. To the contrary, approximately 12 per cent of the hospitals have not established a nursing service department at all but surbodinate it to the other department. In this respect, it is required that a new hospital organization be made to acknowledge the independent function of the nursing department. In 76 per cent of the hospitals they have advisory committees under the nursing department, such as a dormitory self·regulating committee, an in-service education committee and a nursing procedure and policy committee. 9. Personnel arrangement and working conditions of nurses 1) The ratio of nurses to patients is as follows: In university hospitals, 1 to 2.9 for hospitalized patients and 1 to 4.0 for out-patients; in religious hospitals, 1 to 2.3 for hospitalized patients and 1 to 5.4 for out-patients. Grouped together this indicates that one nurse covers 2.2 hospitalized patients and 4.3 out-patients on a daily basis. The current medical treatment law stipulates that one nurse should care for 2.5 hospitalized patients or 30.0 out-patients. Therefore the statistics indicate that nursing services are being peformed with an insufficient number of nurses to cover out-patients. The current law concerns the minimum number of nurses and disregards the required number of nurses for operation rooms, recovery rooms, delivery rooms, new-born baby rooms, central supply rooms and emergency rooms. Accordingly, tile medical treatment law has been requested to be amended. 2) The ratio of doctors to nurses: In university hospitals, the ratio is 1 to 1.1; in national of public hospitals, 1 to 0.8; in religious hospitals 1 to 0.5; and in private hospitals 1 to 0.7. The average ratio is 1 to 0.8; generally the ideal ratio is 3 to 1. Since the number of doctors working in hospitals has been recently increasing, the nursing services have consequently teen overloaded, sacrificing the services to the patients. 3) The ratio of nurses to clerical staff is 1 to 0.4. However, the ideal ratio is 5 to 1, that is, 1 to 0.2. This means that clerical personnel far outnumber the nursing staff. 4) The ratio of nurses to nurse's-aides; The average 2.5 to 1 indicates that most of the nursing service are delegated to nurse's-aides owing to the shortage of registered nurses. This is the main cause of the deterioration in the quality of nursing services. It is a real problem in the guest for better nursing services that certain hospitals employ a disproportionate number of nurse's-aides in order to meet financial requirements. 5) As for the working conditions, most of hospitals employ a three-shift day with 8 hours of duty each. However, certain hospitals still use two shifts a day. 6) As for the working environment, most of the hospitals lack welfare and hygienic facilities. 7) The salary basis is the highest in the private university hospitals, with enterprise hospitals next and religious hospitals and national or public ones lowest. 8) Method of employment is made through paper screening, and further that the appointment of nurses is conditional upon the favorable opinion of the nursing directors. 9) The unemployment ratio for one year in 1971 averaged 29 per cent. The reasons for unemployment indicate that the highest is because of marriage up to 40 per cent, and next is because of overseas employment. This high unemployment ratio further causes the deterioration of efficiency in nursing services and supplementary activities. The hospital authorities concerned should take this matter into a jeep consideration in order to reduce unemployment. 10) The importance of in-service education is well recognized and established. 1% has been noted that on the-job nurses. training has been most active, with nursing directors taking charge of the orientation programs of newly employed nurses. However, it is most necessary that a comprehensive study be made of instructors, contents and methods of education with a separate section for in-service education. 10. Nursing services'activities 1) Division of services and job descriptions are urgently required. 81 per rent of the hospitals keep written regulations of services in accordance with nursing service manuals. 19 per cent of the hospitals do not keep written regulations.

  • 세계경제 및 환경의 변화에 따라 농산물의 불안정적인 수급으로 인한 문제점이 노출되고 있으며, 우리나라의 경우 농산물의 안정적인 확보를 위하여 국가 전략적 차원에서의 해외농업투자의 필요성이 요구되고 있다. 하지만 정부차원의 지원 미진, 해외 농업에 대한 정보 및 기술 미비, 개발자금 확보의 어려움, 장기간의 투자금 회수기간, 사후관리 미흡 등의 이유로 성과를 이루지 못하고 있는 실정이며, 특히 해외 농산물의 국내 반입 시 관세의 장벽, 물류 유통비용 등으로 가격 경쟁력이 떨어지고 있어 국내에 반입되지 못하고 있는 실정이다. 이에 본 연구에서는 우리나라의 해외농업투자의 기본개념 및 실태를 살펴보고 해외농업투자의 필요성과 고려사항, 문제점 등을 도출하여 해외에서 재배된 농산물의 경쟁력을 위한 유통 측면에서의 개선방안을 정부의 간접적인 지원, 유통 현대화 및 유통정보기능 강화, 유통시설, 수송루트, 하역업무개선, 경쟁력 확보를 위한 정부의 정책적 지원, 교육 훈련을 통한 전문인력 양성 등 다섯 가지 측면에서 제시하였다.
