Recent improvements in living standard and development in medical care led to an increased interest in life expectancy and personal health, and also led to a more demand for higher quality of life. Thus, the problem of women's health draw a fresh interest nowadays. Since late-middle aged women experience various physical and socio-psychological changes and tend to have chronic illnesses, these women have to take initiatives for their health control by realizing their own responsibility. The basic elements for a healthy life of these women are understanding of their physical and psychological changes and acceptance of these changes. Health promoting behaviors of an individual or a group are actions toward increasing the level of well-being and self-actualization, and are affected by various variables. In Pender's health promoting model, variables are categorized into cognitive factors(individual perceptions), modifying factors, and variables affecting the likelihood for actions, and the model assumes the health promoting behaviors are affected by cognitive factors which are again affected by demographic factors. Since Pender's model was proposed based on a tool broad conceptual frame, many studies done afterwards have included only a limited number of variables of Pender's model. Furthermore, Pender's model did not precisely explain the possibilities of direct and indirect paths effects. The objectives of this study are to evaluate Pender's model and thus propose a model that explains health promoting behaviors among late-middle aged women in order to facilitate nursing intervention for this group of population. The hypothetical model was developed based on the Pender's health promoting model and the findings from past studies on women's health. Data were collected by self-reported questionnaires from 417 women living in Seoul, between July and November 1994. Questionnaires were developed based on instruments of Walker and others' health promotion lifestyle profile, Wallston and others' multidimensional health locus of control, Maoz's menopausal symptom check list and Speake and others' health self-rating scale. IN addition, items measuring self-efficacy were made by the present author based on past studies. In a pretest, the questionnaire items were reliable with Cronbach's alpha ranging from .786 to .934. The models for health promoting behaviors were tested by using structural equation modelling technique with LISREL 7.20. The results were summarized as follows : 1. The overall fit of the hypothetical model to the data was good (chi-square=4.42, df=5, p=.490, GFI=.995, AGFI=.962, RMSR=.024). 2. Paths of the model were modified by considering both its theoretical implication and statistical significance of the parameter estimates. Compared to the hypothetical model, the revised model has become parsimonious and had a better fit to the data (chi-square =4.55, df=6, p=.602, GFI=.995, AGFI=.967, RMSR=.024). 3. The results of statistical testing were as follows : 1) Family function internal health locus of control, self-efficacy, and education level exerted significant effects on health promoting behaviors(${\gamma}_{43}$=.272, T=3.714; ${\beta}_[41}$=.211, T=2.797; ${\beta}_{42}$=.199, T=2.717; ${\gamma}_{41}$=.136, T=1.986). The effect of economic status, physical menopausal symptoms, and perceived health status on health promoting behavior were insignificant(${\gamma}_{42}$=.095, T=1.456; ${\gamma}_{44}$=.101, T=1.143; ${\gamma}_{43}$=.082, T=.967). 2) Family function had a significance direct effect on internal health locus of control (${\gamma}_{13}$=.307, T=3.784). The direct effect of education level on internal health locus of control was insignificant(${\gamma}_{11}$=-.006, T=-.081). 3) The directs effects of family functions & internal health locus of control on self-efficacy were significant(${\gamma}_{23}$=.208, T=2.607; ${\beta}_{21}$=.191, T=2.2693). But education level and economic status did not exert a significant effect on self-efficacy(${\gamma}_{21}$=.137, T=1.814; ${\beta}_{22}$=.137, T=1.814; ${\gamma}_{22}$=.112, T=1.499). 4) Education level had a direct and positive effect on perceived health status, but physical menopausal symptoms had a negative effect on perceived health status and these effects were all significant(${\gamma}_{31}$=.171, T=2.496; ${\gamma}_{34}$=.524, T=-7.120). Internal health locus and self-efficacy had an insignificant direct effect on perceived health status(${\beta}_{31}$=.028, T=.363; ${\beta}_{32}$=.041, T=.557). 5) All predictive variables of health promoting behaviors explained 51.8% of the total variance in the model. The above findings show that health promoting behaviors are explained by personal, environmental and perceptual factors : family function, internal health locus of control, self-efficacy, and education level had stronger effects on health promoting behaviors than predictors in the model. A significant effect of family function on health promoting behaviors reflects an important role of the Korean late-middle aged women in family relationships. Therefore, health professionals first need to have a proper evaluation of family function in order to reflect the family function style into nursing interventions and development of strategies. These interventions and strategies will enhance internal health locus of control and self-efficacy for promoting health behaviors. Possible strategies include management of health promoting programs, use of a health information booklets, and individual health counseling, which will enhance internal health locus of control and self-efficacy of the late-middle aged women by making them aware of health responsibilities and value for oneself. In this study, an insignificant effect of physical menopausal symptoms and perceived health status on health promoting behaviors implies that they are not motive factors for health promoting behaviors. Further analytic researches are required to clarify the influence of physical menopausal symptoms and perceived health status on health promoting behaviors with-middle aged women.

상품의 이용가능성은 소비자 욕구를 충족시킬 수 있는 중요한 점포 능력 중의 하나이다. 그러나 구매하고자 하는 상품이 없는 품절(stockouts)상황이 발생했을때 소비자는 구매의사 결정의 어려움에 직면하고 이러한 어려움은 소비자의 부정적인 반응, 예컨대 점포에 대한 불만족을 야기한다. 본 연구에서는 상품의 이용가능성 상설, 즉 품절상황에서의 소비자 대체선택행동을 이끌어 내는 결정요인들을 파악하여, 이러한 변수들이 품절에 대한 소비자반응과 행동에 어떠한 영향을 미치는가를 규명하고자 한다. 세부적으로 본 연구에서는 기존 연구들과 달리 구매환경의 상황적인 특성(예: 구매 긴급성, 당황정도), 점포 특성(예: 상품구색, 매장편의성), 소비자 특성(예: 브랜드애호도, 점포애호도) 등에 초점을 맞추어 이러한 요인들이 품절시 소비자반응(상품대체, 구매연기, 점포전환 등의 대체선택행동)에 미치는 영향을 실증적으로 밝히는 것을 목적으로 하였다. 특히 본 연구에서는 선행연구에 비해 상품구색, 전반적인 점포 가격 이미지 등의 점포특성 변수들을 추가적으로 고려하여 분석하였다. 이러한 연구목적을 달성하기 위하여 대형할인마트, 슈퍼마켓 등의 다양한 소매업태에서 품절상황을 경험하고 나오는 353명의 소비자들로부터 자료를 수집하여 다항로짓분석(multinomial logit analysis)을 이용하여 연구모형과 연구가설을 검증하였다. 소비자 선택행동에 대한 MNL 모델 추정결과 품절상황에서 상품대체, 구매연기, 점포전환 행동에 대해 구매의 긴급성, 당황 정도, 구매량, 사전 계획구매, 상품구색, 전반적 점포가격 이미지, 브랜드애호도, 점포애호도 요인들이 소비자 선택행동에 유의한 영향을 미치는 것으로 나타났다. 구체적으로 살펴보면, 품절상황시 소비자의 점포 내 상품대체행동을 이끄는 결정요인으로 구매의 긴급성, 당황정도, 구매량, 사전 계획구매, 상품구색의 다양성, 저렴한 점포가격이미지, 브랜드애호도, 점포애호도 등이 유의하였으며, 구매연기를 유도하는 결정요인으로 구매의 긴급성, 구매량, 브랜드애호도 등으로 판명되었다. 품절시 소비자가 다른 점포로 전환하게 하는 요인은 구매의 긴급성, 구매량, 사전 계획구매, 상품구색의 다양성, 저렴한 점포가격이미지, 브랜드애호도, 점포애호도 등으로 파악되었다. 마지막으로 품절시 점포 편의성과 판매원 서비스 요인들은 소비자 대체 행동에 유의한 영향을 주지 못하였다.

인공지능을 기반으로 한 다양한 연구들이 현대사회에 많은 변화를 불러일으키고 있다. 금융시장 역시 예외는 아니다. 로보어드바이저 개발이 활발하게 진행되고 있으며 전통적 방식의 단점을 보완하고 사람이 분석하기 어려운 부분을 대체하고 있다. 로보어드바이저는 인공지능 알고리즘으로 자동화된 투자 결정을 내려 다양한 자산배분 모형과 함께 활용되고 있다. 자산배분 모형 중 리스크패리티는 대표적인 위험 기반 자산배분 모형의 하나로 큰 자산을 운용하는 데 있어 안정성을 나타내고 현업에서 역시 널리 쓰이고 있다. 그리고 XGBoost 모형은 병렬화된 트리 부스팅 기법으로 제한된 메모리 환경에서도 수십억 가지의 예제로 확장이 가능할 뿐만 아니라 기존의 부스팅에 비해 학습속도가 매우 빨라 많은 분야에서 널리 활용되고 있다. 이에 본 연구에서 리스크패리티와 XGBoost를 장점을 결합한 모형을 제안하고자 한다. 기존에 널리 사용되는 최적화 자산배분 모형은 과거 데이터를 기반으로 투자 비중을 추정하기 때문에 과거와 실투자 기간 사이의 추정 오차가 발생하게 된다. 최적화 자산배분 모형은 추정 오차로 인해 포트폴리오 성과에서 악영향을 받게 된다. 본 연구는 XGBoost를 통해 실투자 기간의 변동성을 예측하여 최적화 자산배분 모형의 추정 오차를 줄여 모형의 안정성과 포트폴리오 성과를 개선하고자 한다. 본 연구에서 제시한 모형의 실증 검증을 위해 한국 주식시장의 10개 업종 지수 데이터를 활용하여 2003년부터 2019년까지 총 17년간 주가 자료를 활용하였으며 in-sample 1,000개, out-of-sample 20개씩 Moving-window 방식으로 예측 결과값을 누적하여 총 154회의 리밸런싱이 이루어진 백테스팅 결과를 도출하였다. 본 연구에서 제안한 자산배분 모형은 기계학습을 사용하지 않은 기존의 리스크패리티와 비교하였을 때 누적수익률 및 추정 오차에서 모두 개선된 성과를 보여주었다. 총 누적수익률은 45.748%로 리스크패리티 대비 약 5% 높은 결과를 보였고 추정오차 역시 10개 업종 중 9개에서 감소한 결과를 보였다. 실험 결과를 통해 최적화 자산배분 모형의 추정 오차를 감소시킴으로써 포트폴리오 성과를 개선하였다. 포트폴리오의 추정 오차를 줄이기 위해 모수 추정 방법에 관한 다양한 연구 사례들이 존재한다. 본 연구는 추정 오차를 줄이기 위한 새로운 추정방법으로 기계학습을 제시하여 최근 빠른 속도로 발전하는 금융시장에 맞는 진보된 인공지능형 자산배분 모형을 제시한 점에서 의의가 있다.

The herbicide has become indispensable as much as nitrogen fertilizer in Korean agriculture from 1970 onwards. It is estimated that in 1991 more than 40 herbicides were registered for rice crop and treated to an area 1.41 times the rice acreage ; more than 30 herbicides were registered for field crops and treated to 89% of the crop area ; the treatment acreage of 3 non-selective foliar-applied herbicides reached 2,555 thousand hectares. During the last 25 years herbicides have benefited the Korean farmers substantially in labor, cost and time of farming. Any herbicide which causes crop injury in ordinary uses is not allowed to register in most country. Herbicides, however, can cause crop injury more or less when they are misused, abused or used under adverse environments. The herbicide use more than 100% of crop acreage means an increased probability of which herbicides are used wrong or under adverse situation. This is true as evidenced by that about 25% of farmers have experienced the herbicide caused crop injury more than once during last 10 years on authors' nationwide surveys in 1992 and 1993 ; one-half of the injury incidences were with crop yield loss greater than 10%. Crop injury caused by herbicide had not occurred to a serious extent in the 1960s when the herbicides fewer than 5 were used by farmers to the field less than 12% of total acreage. Farmers ascribed about 53% of the herbicidal injury incidences at their fields to their misuses such as overdose, careless or improper application, off-time application or wrong choice of the herbicide, etc. While 47% of the incidences were mainly due to adverse natural conditions. Such misuses can be reduced to a minimum through enhanced education/extension services for right uses and, although undesirable, increased farmers' experiences of phytotoxicity. The most difficult primary problem arises from lack of countermeasures for farmers to cope with various adverse environmental conditions. At present almost all the herbicides have"Do not use!" instructions on label to avoid crop injury under adverse environments. These "Do not use!" situations Include sandy, highly percolating, or infertile soils, cool water gushing paddy, poorly draining paddy, terraced paddy, too wet or dry soils, days of abnormally cool or high air temperature, etc. Meanwhile, the cultivated lands are under poor conditions : the average organic matter content ranges 2.5 to 2.8% in paddy soil and 2.0 to 2.6% in upland soil ; the canon exchange capacity ranges 8 to 12 m.e. ; approximately 43% of paddy and 56% of upland are of sandy to sandy gravel soil ; only 42% of paddy and 16% of upland fields are on flat land. The present situation would mean that about 40 to 50% of soil applied herbicides are used on the field where the label instructs "Do not use!". Yet no positive effort has been made for 25 years long by government or companies to develop countermeasures. It is a really sophisticated social problem. In the 1960s and 1970s a subside program to incoporate hillside red clayish soil into sandy paddy as well as campaign for increased application of compost to the field had been operating. Yet majority of the sandy soils remains sandy and the program and campaign had been stopped. With regard to this sandy soil problem the authors have developed a method of "split application of a herbicide onto sandy soil field". A model case study has been carried out with success and is introduced with key procedure in this paper. Climate is variable in its nature. Among the climatic components sudden fall or rise in temperature is hardly avoidable for a crop plant. Our spring air temperature fluctuates so much ; for example, the daily mean air temperature of Inchon city varied from 6.31 to $16.81^{\circ}C$ on April 20, early seeding time of crops, within${\times}$2Sd range of 30 year records. Seeding early in season means an increased liability to phytotoxicity, and this will be more evident in direct water-seeding of rice. About 20% of farmers depend on the cold underground-water pumped for rice irrigation. If the well is deep over 70m, the fresh water may be about $10^{\circ}C$ cold. The water should be warmed to about $20^{\circ}C$ before irrigation. This is not so practiced well by farmers. In addition to the forementioned adverse conditions there exist many other aspects to be amended. Among them the worst for liquid spray type herbicides is almost total lacking in proper knowledge of nozzle types and concern with even spray by the administrative, rural extension officers, company and farmers. Even not available in the market are the nozzles and sprayers appropriate for herbicides spray. Most people perceive all the pesticide sprayers same and concern much with the speed and easiness of spray, not with correct spray. There exist many points to be improved to minimize herbicidal phytotoxicity in Korea and many ways to achieve the goal. First of all it is suggested that 1) the present evaluation of a new herbicide at standard and double doses in registration trials is to be an evaluation for standard, double and triple doses to exploit the response slope in making decision for approval and recommendation of different dose for different situation on label, 2) the government is to recognize the facts and nature of the present problem to correct the present misperceptions and to develop an appropriate national program for improvement of soil conditions, spray equipment, extention manpower and services, 3) the researchers are to enhance researches on the countermeasures and 4) the herbicide makers/dealers are to correct their misperceptions and policy for sales, to develop database on the detailed use conditions of consumer one by one and to serve the consumers with direct counsel based on the database.

배경: 조직판막에 남아있는 세포물질은 환자의 면역반응과 관련이 있고 석회화의 원인이 된다고 알려져 있으며 탈세포화 된 판막조직의 세포외 기질은 숙주세포(host cell)가 부착되고 내피화(endothelialization)되어 조직으로 재구성되게 하는 생물학적 지자체로도 사용될 수 있다. 그러므로 탈세포화는 조직판막의 면역반응 최소화와 지자체의 형성에 가장 중요한 부분이다. 탈세포화를 위해 많은 방법과 약제들이 개발 되어 왔다. 그러나 화학적 혹은 효소적 탈세포화 방법에 앞서 삼투압(osmolality)을 이용한 저장성 용액 처치에 대한 효과를 보여준 논문은 드물다. 본 연구는 탈세포화에 있어서 저장성 용액 처치의 효과를 밝히고 아울러 탈세포화 시 적절한 온도, 처치시간, sodium dodecylsulfate (SDS)의 농도를 밝히고자 시행되었다. 대상 및 방법: 돼지 판막을 여러 조건 즉 SDS농도(0.25%, 0.5%), 저장성용액 처치시간(6, 12, 24시간), 온도($4^{\circ}C$, $20^{\circ}C$)를 달리하여 일종의 이온세정 용매인 SDS를 이용하여 탈세포화를 하였다. 저장성 용액에 노출시키지 않은 군을 B군으로 하고 동 수의 돼지 판막을 같은 조건에서 SDS에 처치하기 전에 저장성용액에 노출 시켰다(A군). 저장성 용액에의 노출은 4, 7, 14시간, $4^{\circ}C$와 $20^{\circ}C$로 구분하여 각각 탈세포화의 정도를 조사하였다. 탈세포화와 세포외 기질의 보존 정도는 hematokylin-eosin (H-E) 염색으로 표본을 관찰하였다. 결과: SDS의 두 농도, 0.25%, 0.5%에서 탈세포화의 정도의 차이는 발견할 수 없었다. $4^{\circ}C$ 환경에서 24시간 SDS로 처치한 것이 A, B군 모두에서 가장 양호한 탈세포화를 소견을 보였고 $20^{\circ}C$에서는 탈세포화 정도에 차이가 없었다. 저장성 용액으로 처치한 A군 모두에서 같은 조건의 처치하지 않은 B군에 비래 더 양호한 탈세포화 소견을 보였다. $4^{\circ}C$, 14시간 저장성용액에 노출된 판막이 가장 좋은 탈세포화의 소견을 보였고, $20^{\circ}C$의 저장성 용액에 노출된 판막은 양호한 탈세포의 소견을 보였으나 심한 세포외 기질의 파괴를 관찰할 수 있었다. 결론: 판막조직의 탈세포화에 있어서 삼투압처리를 이용한 저장성 용액 처치는 매우 효과적인 방법으로서, 돼지 판막조직의 탈세포화에 꼭 적용되어야 할 방법으로 생각된다 저장성 용액에의 노출이 탈세포화에 필요한 화학적 세정제(chemical detergent)의 농도를 줄이고 이러한 세정제의 농도나 노출시간을 줄일 수 있는지 그리고 세포외 기질의 변화에 어느 정도 영향을 주는지에 대해 추가적인 연구가 필요할 것으로 생각된다.

对营销和广告经理来说, 理解消费者的偏好和使用的媒体类型是非常有必要的, 尤其是在如今市场细分的情况下. 清晰的理解能帮助经理更有效的选择合适的媒体. 而且由于性格特征的不同, 个人对媒体类型的选择和使用都不相同. 本文测试了一个性格特征, 即感知追求. 这是在测试 "新" 媒体偏好和使用的文献中尚未出现的. 感知追求是被定义为 "一种对变化, 新颖和复杂的感觉的需要和经历. 以及为承担这些经历愿意承受生理的和社会的风险" (Zuckerman 1979). 根据文献回顾, 我们提出了6个假设. 我们尤其关注使用与满足理论(Katz 1959), 这个理论解释了为什么人们选择媒体类型和他们使用不同媒体类型的动机的原因. 目前的理论表明高感知追求者(HSS), 由于他们对新颖, 激励和非传统的内容和想象的需要, 他们会更多的使用新媒体. 因此, 我们假设高感知追求者比低感知追求者(LSS)(H2a)或中等感知追求者(MSS)(H2b)会更多的使用网络而不是广播(H1a)或印刷媒体(H1b). 另外, 高感知追求者有更多的社交活动及朋友, 因此他们会比低感知追求者(a) 和中等感知追求者(b)更多的使用社交网络网页例如Facebook/MySpace(H3) 以及聊天室(H4). 感知追求者可以显示出一系列的行为包括抑制解除. 我们认为具有高水平去抑制的人们比低水平或中等水平的人们会更多的使用社交网络如Facebook/MySpace (H5) 和聊天室(H6). 我们的数据来源于对参加极限运动的参与者的网上调查. 为得到这个群组的信息, 我们使用雪球样本技术的提高版, 即连锁推荐方法来选择应答者. 这种方法被认为是对隐藏人群进行有效估算的方法(Heckathorn, 1997). 最终的有效样本包括1108名应答者. 主要是年轻人(56.36%在34岁以下), 男性(86.1%)和中产阶级(58.7%的家庭收入超过50,000美元). 我们用这个样本来进行感知追求的研究. 我们用简要感知追求量表来测试感知追求(Hoyle et al. 2007). 我们用自我报告使用过的不同媒体类型来测量媒体使用. 结果并不支持H1a和b. 高感知追求者并没有更多的使用网络这样的媒体. 事实上, 同其他的媒体类型相比, 这个平均水平是较低的. 高感知追求者使用最多的媒体类型时印刷媒体, 这说明了一种对主流的反抗. 结果支持H2a和b. 高感知追求者比低感知或中等感知追求者更多的使用网络. 进一步的分析揭示了在高感知和低感知追求者之间在使用印刷媒体方面有显著不同. 高感知追求者在他们感兴趣的极限运动方面会追求更专业的印刷出版物. 假设3a和b 揭示了高感知追求者比低感知或中等感知追求者更多的使用Facebook/MySpace. 在使用聊天室方面低感知和高感知追求者之间没有显著差距. 所以结果也不支持假设H4a, 但是H4b的结果是显著的. 不同抑制解除水平的应答者被认为使用Facebook/MySpace 和聊天室的水平也不同. 去抑制水平高比低水平或中等水平的使用Facebook/MySpace的水平高. 所以H5a和b 被支持. 类似的, H6b也被支持. 去抑制水平高的人们使用聊天室的概率显著多于中等水平的但并不多于低水平的人们(H6a). 这些结果为管理者提供了一些有趣的见解. 第一, 尽管高感知追求者比低感知或中等感知追求者更多的使用在线媒体, 但他们使用在线媒体仍然少于印刷或广播媒体. 广告执行者们不应该对这个重要的客户群过分的强调在线媒体. 第二, 社交媒体, 例如Facebook/MySpace和聊天室会是接近这个群体的有潜力的方法. 最后, 对去抑制水平高的群体, 有公共关系方面的启示. 这些个体更倾向于一些社会风险的行为. 这些直接的启示包括因特网捕食者和未来的雇主. 本研究的一个不足是受访者都是参与极限运动的. 这本身就是一个高感知追求者活动. 更大范围的人群需要被测试.

互联网快速增长, 已经成为一个重要的零售渠道, 并出现了各种互联网零售商, 又称电子零售商. 一种网上代购店蓬勃发展起来, 吸引了国内市场的消费者. 这是一种独特的电子零售商, 他们从全球购买国内市场尚未进口的名牌产品, 寄给个人购买者, 并收取服务费. 有些消费者喜欢高端独特但无进口资格的品牌, 却因付款问题或国内的寄送问题很难直接从海外零售商处购买. 在韩国, 网上代购店的数量和销售量快速增长-2008年韩国有超过430个活跃商店和5000亿销售额, 需要这种代购服务的消费者数量也在急剧增加. 这种电子零售的概念源于 "代理中介采购" -种存在已久的形式和内容多样化的代购. 通常市场经营者面对的是购买者的代表人而非本人, 由消费者决定的代理购买者影响越来越大. 很多市场营销和心理学领域的学者都研究过代理对消费者购买决定的影响范围. 然而, 在互联网商务方面却没有深入的研究. 此外, 网上代购店作为代理购买者, 将海外品牌或零售商同国内消费者连接起来. 它有一个特点, 代理购买国, 即代购商品所在国的形象对消费者的态度和购买倾向有重要影响, 还会影响消费者在进行信息处理时所感知的风险维度. 然而, 尽管对原产国不同维度的影响已有很多研究, 对网络内容的相关研究却很少. 已有研究证明, 原产国信息作为产品制造情况的线索对消费者的评价有正面影响, 但对这种形式下网络代理购买国的形象和产品评价之间的关系进行的研究却很少. 因此, 作者们发这种具体的零售渠道很值得研究, 重点结构间的系统关系以及各自不同的路径很值得探索. 已有研究证明代购原产国, 也就是代购店购买商品所在地的形象, 不仅对消费者的产品评价(包括态度和购买意向)有正面影响, 还对感知风险的三个维度有负面影响: 产品相关, 行员相关, 以及购买后的风险. 在所有的感知风险中, 由于对产品性能的高度不确定性, 产品相关的风险受负面形象的影响最大(${\beta}$= -.30), 其次是航运相关风险(${\beta}$= -.18)和购买后的风险(${\beta}$= -.15). 对产品态度(${\beta}$= .10)和购买倾向(${\beta}$= .14)也有一定影响. 此外, 经证明, 感知风险的三个维度通过对产品的态度作为中介, 对购买倾向有负面的的影响(${\beta}$= -.57: 产品相关风险${\rightarrow}$ 对产品的态度; ${\beta}$= -.24: 航运相关风险${\rightarrow}$ 对产品的态度; ${\beta}$= -.44: 购买后风险${\rightarrow}$ 对产品的态度). 从更多的分析可以看出, 消费者处理信息的路径会因其对产品知识的等级不同而改变. 新手购买者知识等级较低, 只会考虑感知风险, 而知识等级较高的专家购买者则会考虑到代理购买国的形象和感知风险两个方面, 对产品形成更准确更系统的态度和决定. 这同之前的研究相一致. 本研究提出一些理论和实际的建议. 代理购买国的形象会影响消费者的风险感知和行为结果, 因此应谨慎选择代购国家, 如果这种新型的零售业务快速发展起来, 应控制好消费者的风险, 无论是新手或专家. 另外, 由于消费者各自知识等级不同, 处理信息的路径也不尽相同, 针对不同消费者应形成成熟的市场营销手段. 新手购买者需要风险消减方面的建议, 以帮助他们形成更好的态度, 而专家购买者应选择更好更发达的国家进行代购. 消费者可以使用担保策略来促使在线购物的顺利进行. 本研究没有拘于概括性等限制. 在今后的研究中, 应进一步测试比较有相关结构的不同电子零售商.

Objective : To investigate the current status of prescription drugs in Oriental medical institutes and to draw up a future plan for the revitalization of Oriental medical health insurance, this survey has been performed. Method : The survey has been made with 321 doctors working at Oriental medical institutes in Daegu and Kyungbuk areas for a period of 3 month from June 1, 2010 until September 1, 2010. Result : 1. When it comes to the current status of the use of herbal drugs in Oriental Health insurance, most of doctors surveyed prescribe insurance drugs, and they prescribe insurance drugs to patients, who are less than 20% of total patients visiting their clinics. 2. The awareness of Herbal Health Care Drugs is investigated. When it comes to the understanding of the difference between insurance drugs(powder type drugs) and granular type drugs, doctors admit that they differ only in one aspect, whether or not their being covered by health insurance. Based on the survey results on the understanding of insurance coverage of granular type drugs, doctors, even though they long for granular type drugs to be accepted as insurance drugs, are worrying whether the number of outpatients might dwindle due to increased insurance co-payments. They also point out that the biggest obstacles in the expansion of the granular type drugs as insurance drugs are the lack of understanding of the government and the objection of the Health Insurance Review and Assesment service (HIRA) for fear of increased insurance claims. 3. Upon investigation on Oriental medicine doctors' understandings of herbal pharmaceutical industry, it is found that doctors' responses on pharmaceutical industry are not all positive ones('new product development and neglect of R&D infrastructure' and 'smallness of industry'). When it is investigated what area needs the greatest improvement in herbal pharmaceutical industry, 'securing sufficient capital, good manufacturing, and strengthening quality control', is the highest. 4. When it is asked what are the most needed in order to improve herbal health insurance medicine, responses such as 'the increase in the accessibility to and the utilization of Oriental medical clinics through the diversification of the means of prescriptions', 'the improvement of insurance benefits(cap adjustments)', 'increase the proportion of high quality medicinal plants', 'the ceiling of co-payments(deductible) at 20,000 won or more', 'expansion of the choices of formulations', 'formulational expansions of tablets and pills', and finally 'admittance and expansion of granular type drug as insurance drug' are the highest. 5. Upon investigating the general characteristics of the current status of the usage of Oriental health care herbal drugs, the followings are observed. First, the frequency of use of health insurance drugs by the doctors who use health insurance with general characteristics shows similar differences in case of total monthly sales amount (p<0.001), average number of daily patients (p<0.05). Secondly, as to the willingness of the expanded usage of insurance drugs, similar differences are observed in case of total monthly sales amount (p<0.05). 6. Upon investigating the general characteristics of the perception of Herbal health care drugs, the followings are observed. First, inspecting general characteristics and insurance claims due to increased co-payments(deductible amount) reveals similar differences in case of working period (p<0.01) and in case of total monthly sales amount (p <0.01). Secondly, inspecting general characteristics and the obstacles that hinder granular type drugs from being accepted as health care insurance drugs shows similar differences in case of working period (p<0.05). 7. Upon investigating the general characteristics of the understanding of Oriental Herbal pharmaceutical companies, the followings are observed. First, opinions on the general characteristics of pharmaceutical companies, when examined with variance analysis, shows similar differences in case of total monthly sales amount (p<0.05). Secondly, when opinions are examined on general characteristics and the problems of herbal pharmaceutical companies, similar differences are found in case of working period (p<0.01) and in case of total monthly sales amount (p<0.001). Lastly, opinions on the general characteristics and reforms of pharmaceutical companies, similar differences are observed in case of working period (p<0.001). 8. Upon investigating the general characteristics of the improvement of insurance Herbal drugs, the followings are observed. First, regarding general characteristics and insurance benefits, similar differences are observed in case of working period (p<0.05), in case of total monthly sales amount (p<0.05), and in case of average number of daily patients (p<0.01). Secondly, opinions on the general characteristics and the needs for the improvement of Herbal insurance drugs are examined in 5 different aspects, which are the approval of granular type drugs as insurance drugs, the expanded practices of the number of prescription insurance drugs, the needs of a variety of formulations, the needs of TFT of which numbers of Oriental medical doctors are members for the revision of the existing system, and the needs of adjusting the current ceiling of the fixed amount and the fixed rate. When processed by the analysis of variance, the results show similar differences in case of average number of daily patients (p<0.01). Conclusion : From the results of this study the first measures to take are, to reform overall insurance benefit system, including insurance co-payment system(fixed rate cap adjustment), to expand the number of the herbal drugs to be prescribed matching with insurance benefit accordingly, and to revitalize herbal medicine insurance system through the change of various formulations. In addition, it is recommended to improve the effectiveness of herbal medicine by making plans to enhance the efficacy of herbal medicine and by enabling small pharmaceutical companies to outgrow themselves.
