  • The purpose of this study is to investigate factors related to the intent of using home nursing of chronic disease patients who got out of a university hospital. For the purpose, the study selected 153 patients who were hospitalized and left K university hospital with diagnoses of cancer, hypertension, diabetes and cerebral vascular accident and ordered to be discharged and performed interviews with them and surveys on their medical records to obtain the following results. For this study a direct-interview survey and medical record review was conducted from June 28 to Aug. 30, 1998. The frequency and mean values were computed to find the characteristics of the study subjects, and $X^2$-test, t-test, factor analysis and multiple logistic regession analysis were applied for the analysis of the data. The following results were obtained. 1) When characteristics of the subjects were examined, men and women occupied for 58.8% and 41.2%, respectively. The subjects were 41.3 years old in aver age and had the monthly aver age earning of 0.99 million won or below, which was the most out of the total subjects at 34.6%. Among the total, 87.6% resided in cities and 12.4 in counties. The most left the hospital with diagnosis of cancer at 51.6%, followed by hyper tension at 24.2%, diabetes at 13.7% and cerebral vascular accident at 7.2%. 2) 93.5% of the selected patients had the intent of using home nursing and 6.5%, didn't. Among those patients having the intent, 85.6% had the intent of paying for home nursing and 14.4%, didn't. The subjects expected that the nursing would be paid 9,143 won in aver age and 47.7% of them preferred national authorities as the main servers. 86.3% of the subjects thought that home nursing business had the main advantage of making it possible to learn nursing methods at home and thereby contributing to improving the ability of patients and their facilities to solve health problems. 3) Relations between the intent of use and characteristics of the subjects such as demography-related social, home environment, disease and physical function characteristics did not show statistically significant differences among one another. Compared to those who had no intent of using home nursing, the group having the intent had more cases of male patients, the age of 39 or below, residence in cities, 5 family member s or more, no existence of home nursing servers, leaving the hospital from a non-hospitalized building, disease development for five months or below, hospitalization for ten days or more, non-hospitalization with in the recent one month, two times or over of hospitalization, leaving the hospital with no demand of special treatment, operation underwent, poor results of treatment, leaving the hospital with demand of rehabilitation services, physical disablement and high evaluation point of daily life. 4) Among those patients having the intent of using home nursing, 47.6% demanded technical nursing and 55.9%, supportive nursing. As technical nursing,' inject into a blood vessel ' and 'treat pustule and teach basic prevention methods occupied for 57.4%, respectively, topping the list. Among demands of supportive nursing, 'observe patients 'status and refer them to hospitals or community resources as available, if necessary' was the most with percent age point of 59.5. Regarding the intent of paying for home nursing, 39.2% of those patients wishing to use the nursing responded paying for technical services and 20.2, supportive services. In detail, 70.0% wanted to pay for a service stated as 'inject into a blood vessel', highest among the former services and 30.7%, a service referred to as 'teaching exercises needed to make the body of patients move', highest among the latter. When this was analyzed in terms of a relation between the need(the need for home nursing) and the demand(the intent of paying for home nursing), The rate of the need to the demand was found two or three times higher in technical nursing(0.82) than in supportive nursing(0.35). In aspects of tech ical nursing, muscle injection(1.26, the 1st rank) was highest in the rate while among aspects of supportive nursing, a service referred to as 'teach exercises needed for making patients move their bodies normally'(0.58, the 1st rank). 5) factors I(satisfaction with hospital services), II(recognition of disease state), III(economy) and IV(period of disease) occupied for 34.4, 13.8, 11.9 and 9.2 percents, respectively among factors related to the intent by the subjects of using home nursing, totaled 59.3%. In conclusion, most of chronic disease patients have the intent of using hospital-based home nursing and satisfaction with hospital services is a factor affecting the intent most. Thus a post-management system is needed to continue providing health management to those patients after they leave the hospital. Further, supportive services should be provided in order that those who are satisfied with hospital services return to their community and live their in dependent lives. Based on these results, the researcher would make the following recommendation. 1) Because home nursing becomes more and more needed due to a sharp increase in chronic disease patients and elderly people, related rules and regulations should be made and implemented. 2) Hospital nurses specializing in home nursing should be cultivated.

  • 제조업체와 유통업체의 판매촉진 구사가 증가하면서 이들 사이의 바람직한 판매촉진 비용 분담 방식에 대한 관심도 증가하고 있다. 특히 유통업체 점포를 방문하는 소비자의 비계획구매 요소는 유통업체에게 명시적 잉여를 제공하지만 제조업체에게는 그렇지 않다는 점에서 이를 고려한 판매촉진 비용 분담의 방향 제시가 필요한 것이 현실이다. 문제는 유통업체 방문 소비자의 점포내 비계획구매 요소가 있을 때 제조업체가 어떻게 대응해야 하는지에 대해서는 충분한 설명이 이루어지지 못하고 있다는 점이다. 이러한 문제의식에서 본 연구에서는 유통업체 점포내 비계획구매 요소가 있을 때 제조업체가 구체적으로 공동 판매촉진 행동을 어떻게 전개해야 하는지 조명하고 있다. 본 연구의 주요결과는 다음과 같다: (1) 유통업체 점포 방문 소비자의 비계획구매 수준이 증가할수록 채널 전체의 판매촉진 수준은 높아지고, 제조업체의 비용 분담액도 커진다. (2) 유통업체 점포 방문 소비자의 비계획구매 수준이 증가할수록 채널 전체 판매촉진 비용 중에서 제조업체의 판매촉진 비용 분담 비중은 낮아지고, 유통업체의 판매촉진 비용 분담 비중은 높아진다. (3) 제조업체 이익은 유통업체 점포 방문 소비자의 비계획구매 수준인 b의 증가함수이다. (4) 유통업체가 소비자의 비계획구매 대상 제품을 조달하는데 소요되는 비용 수준이 증가할수록 유통업체 점포 방문 소비자의 비계획구매 수준 증가에 따른 채널 전체의 판매촉진 수준 증가 정도, 제조업체의 판매촉진 비용 분담액 증가 정도, 유통업체의 판매촉진 비용 분담 비중 증가 정도, 제조업체 이윤 증가 정도가 낮아진다.

  • Consumers differ in the way they make a purchase. An audio mania would willingly make a bold, yet serious, decision to buy a top-of-the-line home theater system, while he is not interested in replacing his two-decade-old shabby car. On the contrary, an automobile enthusiast wouldn't mind spending forty thousand dollars to buy a new Jaguar convertible, yet cares little about his junky component system. It is product involvement that helps us explain such differences among individuals in the purchase style. Product involvement refers to the extent to which a product is perceived to be important to a consumer (Zaichkowsky, 2001). Product involvement is an important factor that strongly influences consumer's purchase decision-making process, and thus has been of prime interest to consumer behavior researchers. Furthermore, researchers found that involvement is closely related to perceived risk (Dholakia, 2001). While abundant research exists addressing how product involvement relates to overall perceived risk, little attention has been paid to the relationship between involvement and different types of perceived risk in an electronic commerce setting. Given that perceived risk can be a substantial barrier to the online purchase (Jarvenpaa, 2000), research addressing such an issue will offer useful implications on what specific types of perceived risk an online firm should focus on mitigating if it is to increase sales to a fullest potential. Meanwhile, past research has focused on such consumer responses as information search and dissemination as a consequence of involvement, neglecting other behavioral responses like online merchant selection. For one example, will a consumer seriously considering the purchase of a pricey Guzzi bag perceive a great degree of risk associated with online buying and therefore choose to buy it from a digital storefront rather than from an online marketplace to mitigate risk? Will a consumer require greater trust on the part of the online merchant when the perceived risk of online buying is rather high? We intend to find answers to these research questions through an empirical study. This paper explores the impact of enduring product involvement and perceived risks on required trust level, and further on online merchant choice. For the purpose of the research, five types or components of perceived risk are taken into consideration, including financial, performance, delivery, psychological, and social risks. A research model has been built around the constructs under consideration, and 12 hypotheses have been developed based on the research model to examine the relationships between enduring involvement and five components of perceived risk, between five components of perceived risk and required trust level, between enduring involvement and required trust level, and finally between required trust level and preference toward an e-tailer. To attain our research objectives, we conducted an empirical analysis consisting of two phases of data collection: a pilot test and main survey. The pilot test was conducted using 25 college students to ensure that the questionnaire items are clear and straightforward. Then the main survey was conducted using 295 college students at a major university for nine days between December 13, 2010 and December 21, 2010. The measures employed to test the model included eight constructs: (1) enduring involvement, (2) financial risk, (3) performance risk, (4) delivery risk, (5) psychological risk, (6) social risk, (7) required trust level, (8) preference toward an e-tailer. The statistical package, SPSS 17.0, was used to test the internal consistency among the items within the individual measures. Based on the Cronbach's ${\alpha}$ coefficients of the individual measure, the reliability of all the variables is supported. Meanwhile, the Amos 18.0 package was employed to perform a confirmatory factor analysis designed to assess the unidimensionality of the measures. The goodness of fit for the measurement model was satisfied. Unidimensionality was tested using convergent, discriminant, and nomological validity. The statistical evidences proved that the three types of validity were all satisfied. Now the structured equation modeling technique was used to analyze the individual paths along the relationships among the research constructs. The results indicated that enduring involvement has significant positive relationships with all the five components of perceived risk, while only performance risk is significantly related to trust level required by consumers for purchase. It can be inferred from the findings that product performance problems are mostly likely to occur when a merchant behaves in an opportunistic manner. Positive relationships were also found between involvement and required trust level and between required trust level and online merchant choice. Enduring involvement is concerned with the pleasure a consumer derives from a product class and/or with the desire for knowledge for the product class, and thus is likely to motivate the consumer to look for ways of mitigating perceived risk by requiring a higher level of trust on the part of the online merchant. Likewise, a consumer requiring a high level of trust on the merchant will choose a digital storefront rather than an e-marketplace, since a digital storefront is believed to be trustworthier than an e-marketplace, as it fulfills orders by itself rather than acting as an intermediary. The findings of the present research provide both academic and practical implications. The first academic implication is that enduring product involvement is a strong motivator of consumer responses, especially the selection of a merchant, in the context of electronic shopping. Secondly, academicians are advised to pay attention to the finding that an individual component or type of perceived risk can be used as an important research construct, since it would allow one to pinpoint the specific types of risk that are influenced by antecedents or that influence consequents. Meanwhile, our research provides implications useful for online merchants (both online storefronts and e-marketplaces). Merchants may develop strategies to attract consumers by managing perceived performance risk involved in purchase decisions, since it was found to have significant positive relationship with the level of trust required by a consumer on the part of the merchant. One way to manage performance risk would be to thoroughly examine the product before shipping to ensure that it has no deficiencies or flaws. Secondly, digital storefronts are advised to focus on symbolic goods (e.g., cars, cell phones, fashion outfits, and handbags) in which consumers are relatively more involved than others, whereas e- marketplaces should put their emphasis on non-symbolic goods (e.g., drinks, books, MP3 players, and bike accessories).

  • In collaborative tagging systems such as Delicious.com and Flickr.com, users assign keywords or tags to their uploaded resources, such as bookmarks and pictures, for their future use or sharing purposes. The collection of resources and tags generated by a user is called a personomy, and the collection of all personomies constitutes the folksonomy. The most significant need of the folksonomy users Is to efficiently find useful resources or experts on specific topics. An excellent ranking algorithm would assign higher ranking to more useful resources or experts. What resources are considered useful In a folksonomic system? Does a standard superior to frequency or freshness exist? The resource recommended by more users with mere expertise should be worthy of attention. This ranking paradigm can be implemented through a graph-based ranking algorithm. Two well-known representatives of such a paradigm are Page Rank by Google and HITS(Hypertext Induced Topic Selection) by Kleinberg. Both Page Rank and HITS assign a higher evaluation score to pages linked to more higher-scored pages. HITS differs from PageRank in that it utilizes two kinds of scores: authority and hub scores. The ranking objects of these pages are limited to Web pages, whereas the ranking objects of a folksonomic system are somewhat heterogeneous(i.e., users, resources, and tags). Therefore, uniform application of the voting notion of PageRank and HITS based on the links to a folksonomy would be unreasonable, In a folksonomic system, each link corresponding to a property can have an opposite direction, depending on whether the property is an active or a passive voice. The current research stems from the Idea that a graph-based ranking algorithm could be applied to the folksonomic system using the concept of mutual Interactions between entitles, rather than the voting notion of PageRank or HITS. The concept of mutual interactions, proposed for ranking the Semantic Web resources, enables the calculation of importance scores of various resources unaffected by link directions. The weights of a property representing the mutual interaction between classes are assigned depending on the relative significance of the property to the resource importance of each class. This class-oriented approach is based on the fact that, in the Semantic Web, there are many heterogeneous classes; thus, applying a different appraisal standard for each class is more reasonable. This is similar to the evaluation method of humans, where different items are assigned specific weights, which are then summed up to determine the weighted average. We can check for missing properties more easily with this approach than with other predicate-oriented approaches. A user of a tagging system usually assigns more than one tags to the same resource, and there can be more than one tags with the same subjectivity and objectivity. In the case that many users assign similar tags to the same resource, grading the users differently depending on the assignment order becomes necessary. This idea comes from the studies in psychology wherein expertise involves the ability to select the most relevant information for achieving a goal. An expert should be someone who not only has a large collection of documents annotated with a particular tag, but also tends to add documents of high quality to his/her collections. Such documents are identified by the number, as well as the expertise, of users who have the same documents in their collections. In other words, there is a relationship of mutual reinforcement between the expertise of a user and the quality of a document. In addition, there is a need to rank entities related more closely to a certain entity. Considering the property of social media that ensures the popularity of a topic is temporary, recent data should have more weight than old data. We propose a comprehensive folksonomy ranking framework in which all these considerations are dealt with and that can be easily customized to each folksonomy site for ranking purposes. To examine the validity of our ranking algorithm and show the mechanism of adjusting property, time, and expertise weights, we first use a dataset designed for analyzing the effect of each ranking factor independently. We then show the ranking results of a real folksonomy site, with the ranking factors combined. Because the ground truth of a given dataset is not known when it comes to ranking, we inject simulated data whose ranking results can be predicted into the real dataset and compare the ranking results of our algorithm with that of a previous HITS-based algorithm. Our semantic ranking algorithm based on the concept of mutual interaction seems to be preferable to the HITS-based algorithm as a flexible folksonomy ranking framework. Some concrete points of difference are as follows. First, with the time concept applied to the property weights, our algorithm shows superior performance in lowering the scores of older data and raising the scores of newer data. Second, applying the time concept to the expertise weights, as well as to the property weights, our algorithm controls the conflicting influence of expertise weights and enhances overall consistency of time-valued ranking. The expertise weights of the previous study can act as an obstacle to the time-valued ranking because the number of followers increases as time goes on. Third, many new properties and classes can be included in our framework. The previous HITS-based algorithm, based on the voting notion, loses ground in the situation where the domain consists of more than two classes, or where other important properties, such as "sent through twitter" or "registered as a friend," are added to the domain. Forth, there is a big difference in the calculation time and memory use between the two kinds of algorithms. While the matrix multiplication of two matrices, has to be executed twice for the previous HITS-based algorithm, this is unnecessary with our algorithm. In our ranking framework, various folksonomy ranking policies can be expressed with the ranking factors combined and our approach can work, even if the folksonomy site is not implemented with Semantic Web languages. Above all, the time weight proposed in this paper will be applicable to various domains, including social media, where time value is considered important.

  • 최근 기업 경영에 있어 정보기술의 도입 및 전략적인 활용은 선택이 아닌 필수로 자리잡고 있다. 기업의 전략적인 목표와 정보기술 간의 상호 의존은 기업의 생존 및 성장에 중요한 역할을 하고 있으며, 이에 따라 이미 많은 기업이 지속적으로 정보기술에 투자하고 있다. 정보기술 투자 성과 관련해서는 기업 내부의 요인들과 전략들, 기업외부의 고객까지 여러 가지 복합적인 요소들이 서로 상호작용하고 있기 때문에, 각 요인들을 독립적으로 분리하여 정보기술 투자 성과에 미치는 영향력을 분석하는 것이 쉽지 않다. 이에 본 연구는 기존의 연구들을 바탕으로 정보기술 투자성과에 영향을 줄 수 있는 변수들을 도출하여, 각 변수들의 관계를 수리적인 모델링을 통해 단순화시키고, 시뮬레이션 방법론을 이용하여 각 변수들의 변화에 정보기술 투자 성과는 어떻게 달라지는지를 밝혔다. 본 연구의 결과는 정보기술 투자는 서비스의 품질을 증가시켜 경제학적인 성과들에 간접적으로 영향을 주고, 정보기술 투자와 동시에 소비자 잉여는 증가되지만, 큰 투자비용으로 회사의 이익은 감소하게 된다. 그리고 시간이 지남에 따라 품질 증가에 관한 정보가 고객들 사이에 퍼져 나가게 되므로 최종적으로 기업의 수익을 증가시켜준다. 또한, 정보기술 투자 성과 극대화를 위해서는 회사가 제공하는 서비스와 소비자들의 네트워크 효과 등이 고려되어 정보기술 투자 여부를 결정하고, 회사에 맞는 정보기술 투자 전략을 세워야 함을 시뮬레이션 모형을 통해 확인할 수 있었다. 구체적으로, 한 번에 많은 투자를 할 경우는 단기적인 성과는 클 것으로 기대되나, 장기적으로 좋은 성과가 이뤄지지 않는다. 그러나 정보의 확산 속도가 빠르거나 정보의 장벽이 될 수 있는 정보를 받지 못하는 소비자가 적을 경우 단기에 집중 투자 하는 것이 많은 수요를 얻을 수 있다. 또, 여러 번에 걸쳐 투자하는 경우는 적당한 주기를 가지게 될 경우 장기적으로 큰 성과를 낼 수 있음을 확인할 수 있었다. 본 연구는 경제학 모델링과 시뮬레이션을 결합시켜, 각각의 한계를 모두 극복할 수 있는 방법론을 활용했다는 측면과, 정보기술 투자의 성과를 제품 품질의 매개 효과 모형에 적용하여 정보기술 투자와 기업 성과간의 관계를 보여주었다는 측면, 마지막으로 정보기술 투자 전략 및 정보의 확산 효과를 반영하여 정보기술 투자의 성과를 확인할 수 있다는 측면에서 의의가 있다.

  • 관상수재배(觀賞樹栽培)의 현황(現況), 생산(生產), 유통과정(流通過程), 문제점(問題點), 전망(展望)과 개선방안(改善方案)을 조사(調査)한 결과(結果)를 요약(要約)하면 다음과 같다. 1. 관상수재배(觀賞樹栽培)의 일반현황(一般現況) (1) 전국(全國)(서울제외(除外))의 관상수재배면적(觀賞樹栽培面積)과 재배자수(栽培者數)는 각각 1,872.02ha, 2,717명(名)으로서 농수산부(農水產部) 집계(集計)와 많은 차이(差異)가 있는데, 이것은 재배업자(栽培業者)들이 조세부담등(租稅負擔等)의 이유(理由)때문에 정확(正確)한 답(答)을 하지 않은 것으로 보여진다. (2) 직업(職業)은 원예(園藝)(관상수포함(觀賞樹包含)), 농업(農業)을 비롯한 일차산업분야(一次產業分野)의 종사자(從事者)들이 대부분이었으며, 공무원(公務員), 회사원(會社員)도 약간 있었다. (3) 관상수재배자(觀賞樹栽培者)는 학력(學歷)이 높을수록 그 수(數)가 많은 경향(傾向)을 보였으며, 연령(年齡)은 청년층(青年層)보다 장년(壯年)에서 노년층(老年層)이 많은 분포(分布)를 보였다. (4) 관상수재배동기(觀賞樹栽培動機)는 취미(趣味)로 시작, 수익(收益)이 높아서 자산저축적(資產貯蓄的)인 취지(趣旨)에서 공한지활용등(空閑地活用等)의 순(順)으로 나타났으며 재배경력(栽培經歷)은 5~10년(年)이 가장 많고, 대체로 5~15년(年)까지의 재배경력(栽培經歷)을 가진 자가 전체(全體)의 약 $\frac{2}{3}$정도를 차지하고 있었다. (5) 관상수재배장소(觀賞樹栽培場所)는 전(田)이 반이상(半以上)이었으며 그밖에 임야(林野), 답(畓), 하천부지등(河川敷地等)의 순(順)으로 전(田)과 답(畓)을 합(合)하면 66.1%로서 전체(全體) 재배장소(栽培場所)의 2/3나 되었다. (6) 관상수(觀賞樹)의 재배면적(栽培面積)은 1,000~3,000평(坪)의 재배자수(栽培者數)가 가장 많고 그 다음이 3,000~10,000평(坪), 10,000평(坪) 이상(以上), 300~1,000평(坪), 300평미만(坪未滿)의 순(順)으로 1정보(町步)(3,000평(坪))이상(以上)의 재배자(栽培者)가 44.3%로 나타났다. 2. 관상수(觀賞樹)의 생산(生產) (1) 관상수원(觀賞樹園)의 경영형태(經營形態)는 부업(副業), 주업(主業), 겸업순(兼業順)이었으며, 경영방식(經營方式)은 기업경영(企業經營), 반자영(半自營), 자영순(自營順)으로서 관상수재배(觀賞樹栽培)에는 고용노동(雇傭勞動)을 많이 사용(使用)하는 것으로 나타났다. (2) 관상수(觀賞樹)의 재배수종(栽培樹種)은 다양한데 30종(種) 미만(未滿)의 재배자(栽培者)가 전체(全體)의 약 3/4, 30종(種) 이상(以上)의 재배자(栽培者)가 전체(全體)의 약 l/4로 나타났다. (3) 1977년(年) 3월말(月末) 현재(現在) 관상수재배자(觀賞樹栽培者)들이 재배(栽培)하고 있는, 10가지 주요관상수종(主要觀賞樹種)은 (1) 향나무류, (2) 철죽류, (3) 회양목, (4) 은행나무, (5) 단풍나무, (6)목련류, (7) 잣나무류, (8) 주목, (9) 사철나무류, (10) 히말라야시다로 나타났다. (4) 출하(出荷)가 곧 가능(可能)한 수종(樹種)은 (1) 향나무류, (2) 회양목, (3) 철죽류, (4) 단풍나무류, (5) 목련류등이었다. 3. 관상수(觀賞樹)의 유통(流通) (1) 관상수(觀賞樹)의 처분(處分)은 주(主)로 중간상인(中間商人)에게 판매(販賣)하고 있었으며, 관상수유통과정(觀賞樹流通過程)은 5가지로 나누어 볼 수 있는데 대부분 중간상인(中間商人)과 하청자(下請者)를 거치며 심지어는 3~4단계의 중간단계(中間段階)를 거치는 유통경로(流通經路)도 실재(實在)하고 있음이 밝혀졌다. 그러므로 관상수(觀賞樹) 거래가격(去來價格)이 마구 조작되고 있어 피해(被害)와 손해(損害)를 입는 것은 생산자(生產者)와 실수요자(實需要者)들이다. 따라서 생산자(生產者)를 보호육성(保護育成)하고 실수요자(實需要者)들에게 보다 싼 적정가격(適正價格)으로 관상수(觀賞樹)를 공급(供給)할 수 있는 단일유통체제(單一流通體制)의 수립(樹立)이 시급히 강구(講究)되어야 할 것이다. (2) 관상수생산자(觀賞樹生產者)들의 관상수판매가격(觀賞樹販賣價格)은 조사결과(調査結果) 입찰가격(入札價格)의 1/2~1/3, 심지어는 수종(樹種)에 따라 1/41~1/5에 불과한 예(例)도 있음이 나타났다. (3) 중간상인(中間商人)들이 얻는 중간이익(中間利益)은 20~50%정도(程度)를 얻는 사람이 대부분인 것으로 본조사결과(本調査結果) 밝혀졌다. 그러므로 관상수유통(觀賞樹流通)의 합리화(合理化)를 기(期)하기 위해서는 중간상인(中間商人)과 하청자(下請者)를 배제(排除)한 생사자(生產者)가 실수요자(實需要者)에게 직매(直賣)할 수 있는 유통경로(流通經路)의 모색(摸索)이 절실히 요청(要請)되며, 생산자(生產者)의 권리(權利)를 보장할 수 있는 방안(方案)도 아울러 검토(檢討)되어야 할 것이다. 4. 관상수(觀賞樹)에 대한 제반(諸般) 문제점(問題點) (1) 최근(最近) 대기업(大企業)에서 관상수재배(觀賞樹栽培) 진출(進出)을 하고 있는데 대해서 관상수재배자(觀賞樹栽培者)들은 (1) 과잉생산(過剩生產)의 초래(招來), (2) 농가(農家)의 부업적(副業的)인 재배(栽培)에 압박(壓迫)을 주기때문 등등의 이유(理由)로 반대의견(反對意見)이 지배적(支配的)이었는데 관계기관(關係機關)에서는 이에 대한 적절(適切)한 대응책(對應策)을 강구(講究)하지 않으면 안될 것이다. (2) 관상수(觀賞樹)의 평탄지(平坦地) 재배금지(栽培禁止)에 대한 반응(反應)은 반대(反對)한다가 지배적(支配的)인 견해(見解)로서 그 이유(理由)를 (1) 신규(新規) 재배자(栽培者)만 규제(規制)해도 법(法)의 목적(目的)이 달성(達成)된다는 것과, (2) 과거(過去)에 합법적(合法的)으로 식재(植栽)한 관상수(觀賞樹)를 무보상(無補賞)으로 옮겨 심게 하는 것은 위법(違法)이 라는 점(點)을 들고 있다. 한편 "농지(農地)의 보전(保全) 및 이용(利用)에 관한 법률(法律)"에 의하여 농수산부(農水產部)가 집계(集計)한 농지환원대상면적(農地還元對象面積)은 전(田)과 답(畓)을 합(合)하여 1,176.39ha로서 이 법(法) 시행(施行)에 앞서 관상수재배자(觀賞樹栽培者)들에 대한 대책(對策)을 강구(講究)한 후(後) 실시(實施)함이 당연(當然)한 처사(處事)요 정당(正堂)한 절차(節次)라고 생각된다. (3) 관상수(觀賞樹)의 대외수출(對外輸出)은 1970년(年) 최초로 편백, 산수유, 오동나무를 수출하기 시작하여 2~3년간 호조(好調)를 보여오다가 최근 부진(不振)현상을 겪고 있는데, 재배업자(栽培業者)들은 그 이유(理由)를 (1) 정보(情報)가 빈약(貧弱)하고 장려책(裝勵策)이 없기 때문, (2) 수입국(輸入國)의 경제불황(經濟不況), (3) 기호(嗜好)에 맞는 신수종(新樹種)의 개발(開發)이 없기 때문 등등으로 보고 있다. 그러나 관상수수출(觀賞樹輸出)은 이제 대일의존(對日依存)에서 구미제국(歐美諸國)쪽으로 돌려야 할 것이며 관상수(觀賞樹)도 새로운 양묘기술(養苗技術)과 번식기술(繁殖技術)을 요(要)하는 특이수종(特異樹種)을 개발(開發)하는 것이 관상수(觀相樹) 수출진흥방안책(輸出振興方案策)이라 생각된다. (4) 관상수(觀賞樹)를 식재(植栽)하여 수입(收入)이 있기 전(前) 을류농지세(乙類農地稅) 납부여부(納付與否)에 대한 관상수(觀賞樹) 재배업자(栽培業者)들의 반응(反應)은 납부(納付)하지 않았다가 납부(納付)하였다는 반응(反應)보다 많았다. 한편 전반적(全般的)인 관상수재배지(觀賞樹栽培地에) 대한 을류농지세액(乙類農地稅額)은 대체로 적당하다는 반응(反應)보다는 세액(稅額)이 너무 많다고 응답(應答)한 사람이 많이 있는 것으로 보아 관계기관(關係機關)에서는 을류농지세(乙類農地稅)의 과세기준(課稅基準)에 대한 재검토(再檢討)를 하여 적정과세(適正課脫)를 하여야 할 것으로 사료(思料)된다. 5. 관상수재배(觀賞樹栽培)에 대한 전망(展望) 및 개선방안(改善方案) (1) 관상수(觀賞樹)의 경기(景氣)는 짧으면 앞으로 2~3년(年), 길면 5~10년내(年內)에 좋아질 것으로 비교적 낙관적(樂觀的) 반응(反應)을 보이고 있는 반면, 앞으로 회복될 가능성이 없다고 비관적 반응(反應)을 보인 예도 약간 있었다. (2) 관상수생산전환(觀賞樹生產轉換)에 대한 반응은 현상유지, 현보유량처분후(現保有量處分後) 전환(轉換), 염가라도 정리(定理)하겠다는 순(順)이었으며, 장기적(長期的)인 안목(眼目)으로 계속 확장(擴張)하고자 한다는 반응(反應)은 그리 많지 않았다. (3) 관상수(觀賞樹)의 규격표준화(規格標準化)에 대한 반응(反應)은 찬성(贊成)한다는 반응(反應)이 지배적(支配的)이나 반대(反對)한다는 사람들도 약간 있었다. 그들은 그 이유(理由)를 (1) 동일규격(同一規格)이라도 재배기술(栽培技術)에 의한 수형상황(樹形狀況)에 따라 가격차(價格差)가 크기 때문, (2) 조림묘목(造林苗木)과 달라 규격통일(規格統一)이 어렵기 때문이라고 하였다. (4) 관상수유통과정(觀賞樹流通過程)의 정비책(整備策)으로 유통기관(流通機關)에서 계통적(系統的)으로 관상수(觀賞樹)를 판매(販賣), 처분(處分)하는데 대해서 찬성(贊成)한다는 반응(反應)이 훨씬 많았으며, 반대자들은 (1) 유통전담기관(流通專擔機關)이 독점(獨占)할 경우의 횡포와, (2) 유통전담기관(流通專擔機關)이 영리화(營利化) 되기 쉽다는 것을 우려하고 있었다. (5) 관상수(觀賞樹)의 과잉생산(過剩生產)을 방지(防止)하고 우량관상수(優良觀賞樹)를 생산(生產)하기 위한 방편으로 관상수재배(觀賞樹栽培)의 허가제(許可制) 또는 인가제(認可制)가 대두(擡頭)되고 있는데 대해서 반대(反對)한다가 찬성(贊成)한다는 반응(反應)보다 약간 높게 나타났으며, 반대이유(反對理由)로는 (1) 부업적(副業的) 관상수재배(觀賞樹栽培)가 불가능(不可能)하다는 것과, (2) 권력(權力)과 결탁한 부조리(不條理)를 초래(招來)하기 쉽다는 것을 들고 있었다.

  • Electronic commerce, commonly known as e-commerce or eCommerce, has become a major business trend in these days. The amount of trade conducted electronically has grown extraordinarily by developing the Internet technology. Most electronic commerce has being conducted between businesses to customers; therefore, the researches with respect to e-commerce are to find customer's needs, behaviors through statistical methods. However, the statistical researches, mostly based on a questionnaire, are the static researches, They can tell us the dynamic relationships between initial purchasing and repurchasing. Therefore, this study proposes dynamic research model for analyzing the cause of initial purchasing and repurchasing. This paper is based on the System-Dynamic theory, using the powerful simulation model with some restriction, The restrictions are based on the theory TAM(Technology Acceptance Model), PAM, and TPB(Theory of Planned Behavior). This article investigates not only the customer's purchasing and repurchasing behavior by passing of time but also the interactive effects to one another. This research model has six scenarios and three steps for analyzing customer behaviors. The first step is the research of purchasing situations. The second step is the research of repurchasing situations. Finally, the third step is to study the relationship between initial purchasing and repurchasing. The purpose of six scenarios is to find the customer's purchasing patterns according to the environmental changes. We set six variables in these scenarios by (1) changing the number of products; (2) changing the number of contents in on-line shopping malls; (3) having multimedia files or not in the shopping mall web sites; (4) grading on-line communities; (5) changing the qualities of products; (6) changing the customer's degree of confidence on products. First three variables are applied to study customer's purchasing behavior, and the other variables are applied to repurchasing behavior study. Through the simulation study, this paper presents some inter-relational result about customer purchasing behaviors, For example, Active community actions are not the increasing factor of purchasing but the increasing factor of word of mouth effect, Additionally. The higher products' quality, the more word of mouth effects increase. The number of products and contents on the web sites have same influence on people's buying behaviors. All simulation methods in this paper is not only display the result of each scenario but also find how to affect each other. Hence, electronic commerce firm can make more realistic marketing strategy about consumer behavior through this dynamic simulation research. Moreover, dynamic analysis method can predict the results which help the decision of marketing strategy by using the time-line graph. Consequently, this dynamic simulation analysis could be a useful research model to make firm's competitive advantage. However, this simulation model needs more further study. With respect to reality, this simulation model has some limitations. There are some missing factors which affect customer's buying behaviors in this model. The first missing factor is the customer's degree of recognition of brands. The second factor is the degree of customer satisfaction. The third factor is the power of word of mouth in the specific region. Generally, word of mouth affects significantly on a region's culture, even people's buying behaviors. The last missing factor is the user interface environment in the internet or other on-line shopping tools. In order to get more realistic result, these factors might be essential matters to make better research in the future studies.

  • This Paper Presents a new measurement technique to derive the level of BSRC (Basic Science and Research Capacity) index by use of the factor analysis which is extended with the assumption of the standard normal probability distribution of the selected explanatory variables. The new measurement method is used to forecast the gap of Korea's BSRC level compared with those of major OECD countries in terms of time lag and to make their international comparison during the time period of 1981∼1999, based on the assumption that the BSRC progress function of each country takes the form of the logistic curve. The US BSRC index is estimated to be 0.9878 in 1981, 0.9996 in 1990 and 0.99991 in 1999, taking the 1st place. The US BSRC level has been consistently the top among the 16 selected variables, followed by Japan, Germany, France and the United Kingdom, in order. Korea's BSRC is estimated to be 0.2293 in 1981, taking the lowest place among the 16 OECD countries. However, Korea's BSRC indices are estimated to have been increased to 0.3216 (in 1990) and 0.44652 (in 1999) respectively, taking 10th place. Meanwhile, Korea's BSRC level in 1999 (0.44652) is estimated to reach those of the US and Japan in 2233 and 2101, respectively. This means that Korea falls 234 years behind USA and 102 years behind Japan, respectively. Korea is also estimated to lag 34 years behind Germany, 16 years behind France and the UK, 15 years behind Sweden, 11 years behind Canada, 7 years behind Finland, and 5 years behind the Netherlands. For the period of 1981∼1999, the BSRC development speed of the US is estimated to be 0.29700. Its rank is the top among the selected OECD countries, followed by Japan (0.12800), Korea (0.04443), and Germany (0.04029). the US BSRC development speed (0.2970) is estimated to be 2.3 times higher than that of Japan (0.1280), and 6.7 times higher than that of Korea. German BSRC development speed (0.04029) is estimated to be fastest in Europe, but it is 7.4 times slower than that of the US. The estimated BSRC development speeds of Belgium, Finland, Italy, Denmark and the UK stand between 0.01 and 0.02, which are very slow. Particularly, the BSRC development speed of Spain is estimated to be minus 0.0065, staying at the almost same level of BSRC over time (1981 ∼ 1999). Since Korea shows BSRC development speed much slower than those of the US and Japan but relative]y faster than those of other countries, the gaps in BSRC level between Korea and the other countries may get considerably narrower or even Korea will surpass possibly several countries in BSRC level, as time goes by. Korea's BSRC level had taken 10th place till 1993. However, it is estimated to be 6th place in 2010 by catching up the UK, Sweden, Finland and Holland, and 4th place in 2020 by catching up France and Canada. The empirical results are consistent with OECD (2001a)'s computation that Korea had the highest R&D expenditures growth during 1991∼1999 among all OECD countries ; and the value-added of ICT industries in total business sectors value added is 12% in Korea, but only 8% in Japan. And OECD (2001b) observed that Korea, together with the US, Sweden, and Finland, are already the four most knowledge-based countries. Hence, the rank of the knowledge-based country was measured by investment in knowledge which is defined as public and private spending on higher education, expenditures on R&D and investment in software.
