Purpose - The goal of this research is to examine the influence of Quick Response on the supply chain performance. Furthermore, this study investigates the potential of Quick Response to be a more advanced form of supply chain collaboration program with extensive information sharing activities. Research design, data, and methodology - The mathematical model is developed to represent the two stage supply chain system with a single manufacturer and one retailer. In the numerical study with the proposed mathematical models, three supply chain systems including the traditional system, Quick Response, and the fully shared information system are compared in terms of their profits. Results - The numerical analysis shows both manufacturer and retailer obtain greater profits under Quick Response than in the traditional system. While the fully shared information outperforms Quick Response as well as the traditional system, it results in lower manufacturer's profit compared with Quick Response. Conclusions - According to the numerical examples, Quick Response is the effective supply chain collaboration program that is beneficial to every supply chain member. The fully shared information system, as a more advanced form of collaboration than Quick Response can bring more benefits to the whole supply chain system, but it is necessary to prepare the proper incentive program that enables every member to share its benefits equally.

In this study, we try to understand the role of online social recommendation and the similarity of preferences between the recommender and the recommendee on consumer decisions in the framework of the two stage purchase decision-making process. Applying construal level theory to our context, we expect that the role of social recommendation and the similarity of preferences would vary over the stages in the two-stage decision making process. To test our hypotheses, we collected the data through an incentive compatible experiment, and analyzed the data with nested logit model. As a result, we found that the role of online social recommendation varies over the stages. Consumers take recommendation from similar others at the stage of consideration set formation, but no longer consider it at the stage of final choice. Consumers take recommendation from dissimilar others at the stage of consideration set formation. At the stage of final choice, however, consumers avoid choosing the option recommended by dissimilar others. The results of our study enrich the understanding about the role of social recommendation, and have implication to marketing practitioners who attempt to make online social recommendation system more efficient.

This paper examined the impacts of the welfare reform program, California Work Pays Demonstration Program(CWPDP), implemented in 1992. CWPDP was designed to move welfare recipients into the labor market by reducing the amount of AFDC grants and one-third earned income disregard. The evaluation of the policy impacts on the welfare recipients was conducted in two areas: employment and earnings. This study used a subset of a database created by the California Department of Social Services, and University of California Data Archive and Technical Assistance. The subset is composed of 3,936 AFDC-FG cases selected in LA County: 1,311 control cases and 2,625 experimental cases. The control group was kept on the AFDC rules as of September 1992, while the experimental group was subject to AFDC rule changes implemented under CWPDP. The analyses of the employment and earnings using the random effects probit model and the random effects regression model, respectively, indicated that CWPDP did not effectively encourage female heads to participate in the labor market. It also revealed that CWPDP did not significantly increase the earnings of female heads. The findings imply that the disincentive structure of the public assistance program is not the main barrier preventing female heads from getting jobs and leaving the welfare rolls. Rather, participation in the labor market and exit from welfare is mainly determined by their own demographic characteristics and the economic cycle. Based on the findings, policy implications are suggested on the National Minimum Protection Program in Korea. Those include a flexible exemption rate for the earned income of beneficiaries, affordable child care services, and guaranteed public jobs.

본 연구는 임금과 생산성의 관계에 대한 선행 연구에서 근호자의 생산성 지표로서 인사고과 정보를 활용한 Medoff and Abraham과 Flabbi and Ichino의 연구를 한국 대기업의 인사데이터(2000년, 제조업 근로자)에 적용하여 재현하였다. 임금함수의 OLS 추정과 임금 및 인사고과 분포를 활용한 다항로짓함수 추정을 통해 분석한 결과, 근로자 개인의 생산성을 통제한다고 하더라도 연공임금은 계속 나타났다. 이는 선행연구와 동일하게 연공임금을 설명함에 있어 인적자본 이론보다는 인센티브 이론이 더 적절하다는 것을 시사한다.

The purpose of this study was to examine the factors influencing the attitude toward the increasing role of private health insurance(PHI). In the Korea Welfare Panel Data 2007, a sample of 1,675 (adjusted by weight value: 1,607) respondents on an opinion on promoting PHI was used in the study. With independent variables including socio-demographic characteristics, health status, health-related behavior, and opinions on welfare service, ordered-probit model was used to analyze the attitude toward PHI. Negative opinion on the increasing role of PHI were responded by 54.6%(n=877) of the respondents, whereas 22.2%(n=373) were positive and 23.2%(n=357) were neutral. Old people, the better off, those with worse self-assessed health status, and those having an experience of health examination tend to have the positive attitude toward the increasing role of PHI. Women, those with chronic diseases or disorders and those who do not agree that comprehensive welfare benefits reduce work incentive showed negative attitude toward PHI. When comparing the needs for PHI before and after medical utilization, ex-ante need tends to strengthen the tendency to support private health insurance. This study will contribute to the discussion on the optimal mix of public and private health insurance in Korea by a better recognition of attitude toward PHI and health care system.

From the past to the present, reviews have had much influence on consumers' purchasing decisions. Companies are making various efforts, such as introducing a review incentive system to increase the number of reviews. Recently, as various types of reviews can be left, reviews have begun to be recognized as interesting new content. This way, reviews have become essential in creating loyal customers. Therefore, research and utilization of reviews are being actively conducted. Some studies analyze reviews to discover customers' needs, studies that upgrade recommendation systems using reviews, and studies that analyze consumers' emotions and attitudes through reviews. However, research that predicts the future using reviews is insufficient. This study used a dataset consisting of two reviews written in pairs with differences in usage periods. In this study, the direction of consumer product evaluation is predicted using KoBERT, which shows excellent performance in Text Deep Learning. We used 7,233 reviews collected to demonstrate the excellence of the proposed model. As a result, the proposed model using the review text and the star rating showed excellent performance compared to the baseline that follows the majority voting.

The Human Research Protection Program (HRPP) includes all subject protection activities and entities involved in the process of planning, reviewing, and conducting clinical research and it ultimately aims that research can be conducted ethically and scientifically while protecting the rights and welfare of research subjects. At the beginning of its introduction in Korea, it was settled down by adopting the United States HRPP, especially the form of AAHRPP element and regulations. However, regulations and operating forms of HRPP have been changed according to the Korean domestic research environment. Actually, all the Korean institutions are adopted the Korean HRPP guidelines that have been officially announced by the Ministry of Food and Drug Safety in Korea. Recently, Korean domestic laws such as the "Advanced Regenerative Biology Act" or "In Vitro Diagnostic Medical Device Act" have been dramatically innovated and our research environment becomes to be more complicated. Therefore, the development of a suitable Korean HRPP model considering the Korean research environment is strongly demanded. For the early settle down of the Korean HRPP model, the positive incentive method should be applied, when the HRPP is operated and/ or properly operated. These improvements in the Korean HRPP environment will eventually lead to the appropriate protection of subjects who are participating in human clinical research and the quality improvement of clinical research.

Objectives: An appropriate level of cost support is being proposed to maximize the participation rate. In addition, as the amount of support is highly concentrated at the level of the limit under the current level of supports, the level of cost support is low when the actual level of cost of measuring the working environment exceeds the limit. This paper describes the adjustment of an appropriate cost support rate. Methods: First, this paper analyzes the current cost support status using data from the KOSHA. Second, an alternative for adjusting the cost support rate is presented in consideration of the incentive aspect. Third, we present simulation results for the average cost support rate, the impact of each alternative on finance, and more. Fourth, the most desirable adjustment method is presented after comparing and analyzing the results of various alternatives. Results: In this paper, we present a new scale model. This model is a mixture of flat-rate, fixed rate, and subside cap. It is expected that the new model will not only facilitate participation in businesses with low measurement costs, but also have the effect of controlling measurement costs for institutions that incur greater costs. It is also expected that setting a cap will have the effect of considering government finances and inducing excessively costly institutions to reduce costs. Thus, the new model is likely to be superior to others. If the fourth plan is applied to new businesses and the fifth plan is applied to sustainable businesses, the average cost support rates will be 87.68 percent and 65.18 percent, respectively, and the needed finances will be 2.5 billion won, 18.8 billion won, and 21.3 billion won in total. Conclusions: It seems most desirable to introduce a new model that combines flat-rate, fixed-rate, and subsidy cap systems and achieve an appropriate cost support rate through this model.

최근 탈중앙화 애플리케이션(dApp: decentralized application)의 하나인 P2E(Play-to-earn) 게임이 많은 사회적 관심을 받고 있다. P2E게임은 블록체인 기술을 기반으로 하여 미래성장가능성이 높은 분야로 긍정적인 평가받는 동시에, P2E게임 아이템을 가상화폐 형태로 현금화할 수 있다는 점 때문에 사행성을 가지고 있다는 부정적인 평가도 받고 있다. 이런 상황에서 본 연구는 사용자들이 P2E게임을 지속적으로 사용하고자 하는 의도에 영향을 미치는 요인에 대해 살펴보고자 한다. 헤도닉 정보시스템 사용의도에 관한 선행연구를 바탕으로, 본 연구는 선행요인을 인지된 재미, 경제적 인센티브, 그리고 사회적 영향으로 제시하고, 사회적 영향에 주는 요인을 동료 및 외부 영향으로 나누어 살펴보았다. 연구모델을 P2E게임을 플레이한 경험이 있거나 인지하고 있는 우리나라 성인 350명을 대상으로 데이터를 수집하여 구조방정식 모형으로 검증하였다. 분석결과, 인지된 재미와 주관적 규범은 P2E게임을 지속적으로 사용하고자 하는 의도에 긍정적 영향을 유의미하게 주는 것으로 나타났으나, 경제적 인센티브는 유의미하게 나타나지 않았다. 그리고 동료 영향과 외부 영향은 주관적 규범에 유의미한 긍정적 영향을 주는 것으로 분석되었다. 본 연구는 게임업계, 정부, 게임사용자 등 여러 이해 당사자들의 P2E게임에 대한 평가가 첨예한 상황에서 발전적인 사회적 논의를 위한 근거 자료로 활용될 수 있을 것이다.
