Purpose: The purpose of this study was to examine morale and related factors of hospital based home care nurses. Method : The subjects were 159 home care nurses from 94 hospitals and clinics which were operating home care programs around the country. Data were collected for 40days from March 14, to April 24, 2005. The questionnaire consisted of 51 items including 12 general variables and 39 items of nurses' morale. The reliability of the questionnaire by Cronbach's ${\alpha}$, was .88. Result : The level of the morale was found as mean score 2.69 in 4 point scale The high ranks of morale were self actualization($3.05{\pm}0.43$) and job satisfaction($3.03{\pm}0.43$), the factors which showed lower points were evaluation of work ($2.47{\pm}0.53$), welfare($2.42{\pm}0.42$), promotion system ($2.35{\pm}0.45$) and wages($2.23{\pm}0.54$). The level of morale according to the general variables were significantly different in such variables ; home care nursing antecedent(p = .000), motivation for job selection(p= .030), intention to quit the job(P= .000). Variables of intention to quit the job(15.7%) and home care nursing antecedent; 6.7%(p=.001) showed 22.4% of explanatory persuasion effect on level of morale. Conclusion : To improve a morale of home care nurses, the arrangement of nursing department should be consider nurse's aptitude and interest and allow them to have longer period of work in that part. Also wages, promotion system and welfare should be reformed as relevant as their career.

After the spread of COVID-19 in 2020, the country's Crisis Alert Level went up to the highest level, Level 4. Respond of COVID-19 pandemic, Governments, and cities secured each province's duty for the citizens. The government provided health assistance first and stepped forward to support the necessary resources for the citizens. Busan City proposed policy response to prepare and implement the Corona support for each county as well. The high occupant rate of self-business owners lost basic incomes, and the effect varies on industries. In our paper, to avoid any crisis in such an epidemic, we propose a clustering analysis for the guidance of policy support for Busan City. By analyzing patterns and clustering on districts and Sectors, we would like to provide reference materials for determining the direction of support and guiding preemptive response in the event of a similar epidemic.

PURPOSES : The purpose of this study is to develop a methodology for estimating additional carbon emissions due to freeway incidents. METHODS : As our country grows, our highway policy has mainly neglected the environmental and social sectors. However, with the formation of a national green growth keynote and an increase in the number of people interested in environmental and social issues, problems related to social issues, such as traffic accidents and congestion, and environmental issues, such as the impact of air pollution caused by exhaust gases that are emitted from highway vehicles, are beginning to be discussed. Accordingly, studies have been conducted on a variety of environmental aspects in the field of road transport, and for the quantitative calculation of greenhouse gas emissions, using various methods. However, in order to observe the effects of carbon emissions, microscopic simulations must use many difficult variables such as cost, analysis time, and ease of analysis process. In this study, additional greenhouse gas emissions that occur because of highway traffic accidents were classified by type (incident handling time, number of lanes blocked, freeway level of service), and the annual additional emissions based on incidents were calculated. According to the results, congestion length and emissions tend to increase with an increase in incident clearance time, number of occupied lanes, and worsening level of service. Using this data, we analyzed accident data on the Gyeong-bu Expressway (Yang-Jae IC - Osan IC) for a year. RESULTS : Additional greenhouse gas emissions that occur because of highway traffic accidents were classified by type (incident handling time, number of lanes blocked, freeway level of service) and annual additional emissions caused by accidents were calculated. CONCLUSIONS : In this study, a methodology for estimating carbon emissions due to freeway incidents was developed that incorporates macroscopic flow models. The results of the study are organized in the form of a look-Up table that calculates carbon emissions rather easily.

Objectives: The purpose of this study is the work environment management method through risk assessment and investigation of the work place that deals with Ammonium nitrate, based on information in and outside the country. Methods: This study suggests method of work environment management through risk assessment and investigation of the work place that deals with Ammonium nitrate, and finds out cases of Ammonium nitrate causing hazard, danger and health risk, based on literature investigation. Results: Rats exposed repeatedly to $LD_{50}$ 2,217 mg/kg(rat), $LC_{50}$ 88.8 mg/L(rat, skin) which cause high level of skin irritation, reported 1 $mg/m^3$ of NOAEL, while LOAEL was less than 100 mg/kg for the rats orally administered with the $LD_{50}$ 2,217 mg/kg(rat), $LC_{50}$ 88.8 mg/L(rat, skin), for 13 weeks. Domestically 31,640 ton/y of ammonium nitrate has been used in 22 workplace and the result of workplace assessment was 0.0171-0.9983 $mg/m^3$. ADD was 8.77-59.63 ${\mu}g/kg-day$ according to the exposure scenario. In other words the result of the risk assessment goes beyond the 'standard 1'. Conclusions: Ammonium nitrate creates a high level of irritation and toxicity when coming in breathe it or contact with skin, and is classified as category3 of GHS and specific target organ toxicant (irritating respiratory system). Exposure level at work places needs to be maintained under $1mg/m^3$, to prevent workers from being damaged.

In this paper, it shows optimal inventory level of bicycle sharing service terminal by maintaining the lowest costs. As the interest to environment and exhaustion of resource increases globally, investment to sustainable transportation increases around advanced countries and interest to efficient transportation, managing and consuming of vehicle increases also. Vehicle sharing service is a model of rental car where customer rent cars for short periods of time often by the hour and its users are increasing for the reason that it is more convenient than car rent. In addition, bicycle sharing service is one of the major parts in vehicle sharing program and many of country are already managing it. This paper proposes optimal inventory levels of vehicle sharing service's terminal by using simulation calculating operation costs of vehicle sharing service.

The objective of the study is to review the research materials for menarche including general characteristics of target population surveyed, mean age of subject, menarche experience rates of the subject and mean age at menarche, and to analyze secular trends of age at menarche in Korea from 1935 to 1992. The results of the study summarized as follows; 1. The range of age in the target pulation for menarcheal research was mainly 10-29 age groups, and most of them were middle, high school girls and college students. 2. There was positive relationship among mean age at menarche, level of menarche experiences rates and mean age of the subject(P<0.01). 3. In the relationship between the mean age at menarche and the level of menarche experience rate of the subject, the subject of study with higher menarche experience were more likely to be higher mean age at menarche than those with lower menarche experience rates. In case of menarcheal experience rates at 75-90 percent among the subject, the values of more and median were more close to the actual mean age at menarche under the assumption that all of the subject had experience menarche. 4. The trends of age at menarche during 1935-92 were linear decrement: Y = 85.93-0.036X in the whole country and Y = 91.35-0.039X in Seoul. The rates of secular diminution in age at menarche calculated to be about 4.3 months per decade in the nation-wide, and 4.6 months in Seoul during the periods. 5. To analyze the secular trends in menarcheal age, the researcher should set up criterians including the range of age in target population, the level of menarcheal experience rate and the regional characteristics.

This paper is to examine the bibliographical description of the revolutionary historical archives and the standardization of the archives management in China. The standardization in the field of records and archives management was not initiated on its own way but as a part of national - leveled standardization. As a first step National Committee on Technical Standardization of Literature was established, followed by the establishing of Committee on Technical Standardization of Micro - filming and Committee of Technical Standardization of Paper Form. The standardization of the records and archives management was carried out in the context of functions of these three committees. In 1983 the standardization in the sphere of records and archives management speeded up, when the National Archives Administration formed small organizations which led the standardization work all over the country. A committee of standardization originated from small organizations and it brought a great progress of the standardization. If some opinions on standardization were submitted from records offices or related offices, they were examined by the committee of standardization. The opinions that were submitted by the committee of standardization were examined by the National Archives Administration which proclaimed it officially. The Chinese government commenced to establish the bibliographical data centre for historical archives and materials on the basis of this process of standardization. In the case of the revolutionary historical archives the description was made on the level of sources(provenance), which was sent to the bibliographical data centre for historical archives and materials. The Chinese government set digitalizing as a goal in records and archives management in the middle of 1990's. It was regulated that the description of records item that should be transferred to the center must be digitalized. However, the description of the file level was not made separately being reflected in the process of description of item level. (The second part of the paper will be released in the next volume).

Many paddy cultivating farmers in the country are forced to use their limited resources to produce adequate food for their family, leading to the degradation and reduction in potential of these resources. The yield levels of paddy at the farmers' level and in the Front Line Demonstrations (FLDs) conducted in the farmers' fields is not at par with potential yield of the paddy variety. The gap between potential yield of crop variety and yield realized in FLDs refers to Research gap and the yield gap between FLDs and due to farmers' practice refers to Extension gap. The earlier studies conducted in India in general and in Andhra Pradesh in particular highlighted the existence of both research and extension gaps with reference to paddy. It is essential that, the narrowing of both research and extension gaps is not static, but dynamic considering the influence of technological interventions in boosting paddy yields at FLDs level and at farmers' level and also with the improvement of the yield potential of paddy varieties. This calls for integrated and holistic approaches to address these two gaps and with this background, the researcher aimed at this in depth study. The findings revealed that, research gaps are high with reference to weed management and pest management and extension gaps are high with reference to farm mechanization followed by fertilizer management. Reliable source of seed, capital use and frequency of meetings with Scientists or Agricultural Officers significantly influence the extension gaps in paddy. Farmers also prioritized socio-economic and technical constraints and the analysis infers that, it is high time now for the farmers to adopt the planned technological interventions on scientific scale to minimize the extension gaps to the extent possible. As the enabling environment in the State of Andhra Pradesh is highly encouraging for the farmers with relevant policy instruments in the form of subsidized inputs, free power, credit at concessional rates of interest, constructing irrigation projects etc., the adoption of the proposed technological interventions significantly contribute to minimizing both research and extension gaps in paddy cultivation in Kurnool district of Andhra Pradesh.

Estimated coefficients has serious problems including inconsistency, biasness, etc. because many researches about the effect of fiscal decentralization on a country's economic growth use the traditional OLS method. Researches use the data intactly so that so called "spurious regression" phenomenon exists. This causes fundamental fallacy. This research tries unit root test, cointegration test, and then estimates the United States' economic time series by using VECM. The analysis of the effect of the state level-fiscal decentralization on economic growth shows two long term-equilibriums. During short term-dynamic adjustment, fiscal decentralization and economic growth move the same or different directions. In case of prediction GDP increases steeply and then from 2015 gently; and fiscal decentralization index shows a general reduction trend and then decreases slowly. At local level it shows two long term-equilibriums. During short term-dynamic adjustment, fiscal decentralization and economic growth also move the same or different directions. Impulse response analysis shows the very negative effect of fiscal decentralization on economic growth.
