Background: When evaluating health-economics for cervical cancer prevention policies in Japan, it is important to use Japanese value settings. This study aimed to obtain preference-based measures (preference measures) for hypothesized health states among healthy Japanese women, and to examine differences between the EuroQol-5D (EQ-5D) and standard gamble (SG) instruments. Materials and Methods: The investigation was performed among female students at a nursing university. We used written hypothetical scenarios describing three grades of cervical intraepithelial neoplasia (CIN) and eight stages of cervical cancer, both at diagnosis and after medical intervention. Preference measures were evaluated using both EQ-5D and SG. Results: We received responses from 136 women. The mean number of respondents per stage was 24.6 (SD: 2.7). At diagnosis, average EQ-5D scores for CIN1, CIN2, CIN3, IA1, IA2, IB1, IB2, IIA, IIB, III, and IV stages were 0.84 (0.14), 0.78 (0.12), 0.73 (0.10), 0.78 (0.12), 0.72 (0.12), 0.63 (0.13), 0.64 (0.12), 0.68 (0.08), 0.62 (0.13), 0.55 (0.21), and 0.18 (0.24), respectively. Using one-way analysis of variance with the Tukey-Kramer method for multiple comparisons (each stage vs. CIN1), we found significant differences for IB1 and more advanced stages (p<0.05). After medical intervention, corresponding EQ-5D scores were 0.84 (0.12), 0.81 (0.12), 0.84 (0.12), 0.80 (0.15), 0.78 (0.11), 0.64 (0.15), 0.63 (0.15), 0.71 (0.15), 0.50 (0.17), 0.52 (0.17), 0.21 (0.28). The multiple comparisons identified significant differences for IB1 and more advanced stages, excepting IIA (p<0.05). SG evaluations were more variable and relatively higher than EQ-5D evaluations. Conclusions: We obtained preference measures for three grades of CIN1-3 and eight stages of cervical cancer. In combination with appropriate sensitivity analyses, these preference measures will provide a basis for an economic evaluation of cervical cancer prevention in Japan. We suggest that EQ-5D is appropriate for cost-utility analysis of this topic.

Purpose - A traditional retail market is a place that offers economic opportunity to employees and employers alike it also is a place where the community can meet. The Korean government has invested three trillion won to improve physical and non-physical aspects in traditional retail markets since 2004. However, little research on this has been conducted. We explore this research gap that could lead to theory extension. We analyze consumption behavior with respect to traditional retail markets through an empirical analysis, thus overcoming limits in previous research. We empirically analyze policy effects of traditional retail market projects supported by the Korean government. Research design, data, and methodology - We propose a traditional retail market improvement plan via the relation between cause and effect resulting from the analysis. More specifically, logit analysis was carried out with 1,754 consumers in 16 cities nationwide. In order to analyze consumer consumption behaviors nationwide, the probability was analyzed using a logit model. This research analyzes the link between support and non-support by the Korean government using binary values. The dependent variable is whether Korean government support is implemented; the binomial logistic regression is used as the statistical estimation technique. The object variables are:1 (support) or 0 (nonsupport), and the prediction value is between 1 and 0. As a result of the factor analysis of questions related to attributes of service quality, four factors were extracted: convenience, product, facilities, and service. Results - The results indicate that convenience, product, and facilities have a significant influence on consumer satisfaction in accordance with the government's traditional retail market support. Additionally, the results reveal that convenience, product, facilities, and service all have a significant influence on consumer satisfaction in a traditional retail market's service quality and consumer satisfaction. Finally, the analysis indicates that the highly satisfied traditional retail market customer has a significant influence on revisit intention. Moreover, the results reveal that the highly satisfied traditional retail market customer has a significant influence on recommendation intention. Conclusions - This research focused on consumers nationwide to measure policy effects of traditional retail markets compared to previous research that focused on one traditional retail market or a specific area. We verified the relationship of service quality and customer satisfaction and consumer behavior based on service quality theory. The results indicate that consumer satisfaction of traditional retail markets supported by service quality factors has a significant impact. In a concrete form, the results indicate that these effects are from facility modernization projects and marketing support projects of the Korean government. The results also imply that these facility and management support effects from the Korean government have been consistent. We realize that the Korean government has to selectively support traditional retail markets in major cities and small and medium-sized cities. To that end, the Korean government needs to select a concentration strategy for the revitalization of traditional retail markets.

Purpose - For the past several decades, behavioral economics or behavioral decision theory has undergone rapid development. This study provides a critical review of the development of behavioral economics with a focus on what are deemed to be core theories in the field. Starting from the utility function proposed by Daniel Bernoulli in the 18th century, the development history of utility functions until the emergence of the prospect theory is thoroughly reviewed. Some of the experimental results violating the traditionally assumed utility function and supporting the prospect theory value function are summarized. The most representative principles of rational choice are transitivity, independence from irrelevant alternatives (IIA), and regularity. The development of behavioral economics has been triggered by finding counter-examples to these principles. Some of the choice behaviors discussed in this study as counter-examples to the traditional theories of rational choice are the St. Petersburg paradox; the Allais paradox; gambling behavior; and the various context effects including the similarity effect, attraction effect, and the compromise effect. The Elimination-by-Aspects (EBA) model, which was proposed as an explanation for the similarity effect, is discussed in detail as well. Based on the literature review and further analysis, this study summarizes the relationship between the context effects, prospect theory, and EBA model. Research design, data, and methodology - This study provides an extensive literature review on several important theories in the field of behavioral decision theory and adds some critical comments to the theories and the relationships among them. This study first reviews the development of utility functions. Daniel Bernoulli introduced the concept of utility function to solve the St. Petersburg paradox. In the mid-20th century, Herbert Simon proposed the "satisficing" heuristic and presented a value function with a shape different from traditional utility functions. This study highlights the strengths and weaknesses of several utility functions proposed until the emergence of the prospect theory value function. Results - This study posits that prospect theory and EBA model are the two most important theories in the field of behavioral decision theory. They can explain various choice behaviors that traditional utility maximization analysis has been unable to. The application of these models to various fields is further increasing nowadays. This study explains how prospect theory and the EBA model can be used to explain the context effects. Conclusions - The traditional economic theory relies on a single variable called "utility" in explaining consumer choice. However, this study argues that, in investigating consumer choice, several other variables should also be considered. These are the similarity among alternatives, an alternative's prototypicality within the category, the dominance relationship between alternatives, and the reference point in evaluating alternatives. Due to the development of behavioral economics, we are now closer to a more complete understanding of consumer choice behavior than in the past when we had only a single tool called utility.

본 연구는 청년층의 학력과잉이 경제위기로 어떻게 전개되었으며 또한 이로 인한 교육투자 수익률이 어떻게 변하였는가를 살펴보았다. 이를 위해 본 연구는 경제위기 전인 1996년도 임금자료와 2000년도 임금자료 각각을 직업사전과 비교함으로서 1996년도의 과잉학력률과 2000년도의 과잉학력률을 인적 속성 및 근로자가 종사하는 산업 직종 그리고 사업체 규모 등 다각적으로 살펴보았다. 그리고 경제위기가 과잉학력에 어떻게 영향을 미쳤는지를 희귀분석했다. 그 결과 경제위기 이후 과잉학력이 보다 심화되었음을 알 수 있었다. 그 후 이러한 변화가 교육 투자수익률에 어떤 영향을 미쳤는지를 살피기 위해 각년도 과잉학력자의 시간당 임금과 적정학력자의 임금을 비교하였으며 또한 경제위기가 투자 수익률에 미친 영향을 살피기 위해 회귀분석을 하였다. 그 결과 학력과잉자의 시간당 임금이 적정학력자의 임금보다 여전히 높았으나 경제위기를 겪으면서 그 임금 차의 폭은 상당히 줄어들었음을 알 수 있다. 그러한 추세가 일시적인 것이 아니라 고착화되고 있는지를 살피기 위해 2002년도 자료로도 분석해 본 결과도 마찬가지로 나타났다.

Introduction of TBELs into Korean environmental regulatory system for wastewater may require very careful considerations and appropriate modifications of the TBELs applied in US. The Korean regulations for wastewater are based on uniform regulatory criteria for wastewater effluent discharge and are quite different from the individual permit system in US. In addition, the toxic pollutants regulated in Korea are much less than those in US. Therefore, the effects of TBELs application on the pollutants reduction and the economic feasibility should be carefully assessed for different categories of wastewater sources. In this study, the applicability of TBELs for the industrial categories of Korea was discussed. The TBELs were derived for a sample category, the pulp paper paperboard manufacture, based on the previously reported analytical data from 52 facilities of the domestic pulp paper paperboard manufacture in Korea. It was suggested that the BAT effluent limitations were BOD 30 mg/L, $COD_{Mn}$ 40 mg/L, SS 40 mg/L, T-N 30 mg/L and T-P 4 mg/L and that the allowable effluent loads were $0.31{\sim}1.75kgCOD_{Mn}/ton$-products. Due to the limitation of insufficient data, there were difficult to obtain the important factors to derive more systematic and accurate limitation standards for the pollutants such as the 'Long Term Average (LTA)', the 'Product Normalized Discharge Flow (PNDF)', and the 'Variability Factor (VF)'. However, as the first trial of TBELs determination based on the all available analytical data reported, the procedure and the outcome of the study may provide valuable insight on application of TBELs in Korea.

공시지가 제도가 도입된 이후, 부동산정책에 대한 제반 행정의 기준으로 기능해 왔다. 그러나 최근 공시지가의 적정성에 대한 문제가 제기되고 있다. 토지특성항목이 너무 많아 통계모형 수립이 어렵고, 지역적 경제적 환경이나 개발계획 등이 지가평가모형에 반영되기 어렵기 때문이었다. 이에 본 연구에서는 분석 모형으로 시계열적인, 횡단면적인 변수들을 고려하여 패널 모형 중에서 이원오차성분 모형을 적용하였다. 분석 모형에 토지특성변수, 거시경제변수, 개발사업을 반영하는 변수를 포함시켰다. 분석 지역으로는 파주 LCD 산업단지를 선정한 후, 실증분석을 수행하였다. 분석 결과 토지특성변수들 중에서 14개(31%) 변수만이 유의한 것으로 나타났다. 거시경제적 변동성은 지가에 영향을 미치는 것으로 나타났다. 개발사업을 반영하는 연도변수는 산업단지 지정 이후 지속적으로 유의한 것으로 분석되었다. 이러한 결과들은 지가평가모형을 개선할 때 토지특성항목들은 단순화하고, 거시 경제 변수들과 지역 경제 변수들은 모형에 포함시켜야 한다는 것을 의미한다고 하겠다.

Economic conditions of Korean agriculture have been aggravated since farmers experienced the shortage of labor, instability of farm product price, lack of capital and pressure of opening domestic market. Nevertheless, agriculture must be maintained because structure of national economy can not be progressed without balanced growth of food industry. So the problem that we must solve is to keep agriculture competitive. In that case technology is important in terms of improving productivity, overcoming labor shortage and stabilizing price. This paper is to study the technology adoption on the farm level, focusing on the theories of technology adoption, their empirical test and effect of technology adoption on the farm household income. In this study five theories-independent model, linear model, middle class conservation model, modified middle class conservation model, basic needs and wealfare model- were introduced concerning differentiated technology adoption rate by farmers' class. Based on the survey of controlled strawberry farming in Nonsan County, Chungnam Province, who adopted six kinds of technology, modified middle class conservation model was found to explain five kinds of technology adoption pattern and linear model was useful to explain one kind of technology, that is, irrigation method, These results may mean that controlled strawbary cultivators of middle class were reluctant to accept new technology. There are many variables to effect on the technology accepting rate, that is, farmer's age, labor capacity, education level, cultivation career, size of total cultivated land, and size of strawberry farming land. LOGIT model was used to find which variable influence the technology adoption rate. Results of estimation showed that variables of cultivation career and total land size, of which coefficients were statistically significant at the 5 percent level, might be main influential factors in accepting more than three farming techniques. There was a significant income difference between farm households accepting new methods and those rejecting them. Especially in case of low class of farming group, income of farmers who was adopting new technology was examined to be much higher than that of farmers who did not adopt. This result suggests that new technology play an important role in increasing farm household income. Finally this study emphasized that there is a need to develop proper measure of technology transfer considering various socioeconomic conditions of farm households.

The present research set out to further validate the results that Stromborg (1976) obtained in which a correlation (r= .22, p < .001) was found between the femininity of woman nursing students and their image of nursing. In addition the experimenter set out to elucidate any possible differences in the image of nursing according to (a) religion, (b) the motivation for choosing nursing as well as, (c) the particular area in which the students hoped to work after graduating. The research was conducted by presenting questionnaire type scales including a femininity scale and a nursing image scale, to 301 graduating students attending 4 Three-year nursing schools located within Seoul from November 21st, 1978 to November 30th. The results: 1. There was clearly no relation between femininity and the image of nursing as such (r= .01, p > .43). But upon analyzing the results along five subdimensions of the nursing image variable it was discovered that : (a) if femininity is low, the nursing student tend to view the educational preparation for becoming a nurse in a more positive light (r= -.10, p < .05), and (b) if femininity is high, the students tend to perceive their social role with a positive frame of mind (r= .15, p < .005). 2. There was a significant difference found in the image of nursing as related to the religion of the nursing students, The means ranked as follows (high scores indicate a positive image of the nursing profession). Catholic > Protestant > no religion > Buddhist 3, The difference in the nursing image according to motivation for sellecting the profession emerged as quite significant (F=6.92, p < .001). The rank of the means when the subject group is divided along the dimension of motive is as follows (ranking begins with the most positive nursing image): (a) The profession itself seemed good; (b) after marriage one can do a social type of activity; (c) significant others’advice: (d) the profession matches their high school grade record; (e) it matches the economic situation of the student; (f）no particular reason for their choice: (g) it's easy to get a nursing job after graduation. 4. The particular area of nursing one intended to go into after graduation varied significantly in terms of the image of nursing (F=3.03, p < .005). The means when ranked starting with those having the most positive image of the profession: (a) nurses helping deliveries; (b) hospital nurses: (c) nursing education; (d) school nurses: (e) government nurse supervisors: (f）public health nurses: (g) (students not going into any profession); (h) (students not going into the nursing profession but into some other area).
