본 연구의 목적은 서울과 그 인근 지역에서 수돗물의 질을 끌이지 않고도 마실 수 있는 수준으로 개선한다는 가정 아래 이에 대 한 지불의사액을 결정하고자 할 때 가상상황 가치평가 기법의 입찰게임에서 출발점 편의의 존재 여부를 검정하는 것이다. 모든 가상상황 가치평가 기법 가운데 입찰게임이 가장 정상가격을 얻는 데 가깝기 때문에 지불의사액(WTP)을 절정하기 위하며 3가지(저$.$중$.$고)의 서로 다른 입찰값의 출발점 그룹을 사용하였다. 응답자들은 출발점에 무작위적으로 배정되었고 사전 검사된 면접설문지를 사용하였다. 출발점 편의의 증거를 밝히기 위하여 비모수적 검정과 로짓(Logit)모델을 사용하였다. 본 연구에서는 높은 출발점 집단에서는 높은 지불의사액을, 낮은 집단에서는 낮은 지불의사액을 나타내었으며 이것은 출발점 편의의 존재를 확인하는 것이다. 출발점 편의의 문제는 지불카드나 입찰게임 없이 응답자에게 최대 지불의사액을 직접 질문함으로써 회피할 수 있다. 그러나 이러한 질문은 대답하기에 아주 어렵고, 무응답을 증가시키며 비현실적인 것이 될 수 있다.

Rice farming is not only the most important income resources of Korean farmers but also the roots of Korean traditional culture. Paddy fields have acted as an food supply base but also have contributed to the public multi-functions such as flood control, water conservation, controlling soil erosion, providing recreational and resting spaces, water purification, air cleaning, oxygen supply and air cooling and so on. The public multi-functions of paddy except rice production have not been evaluated before UR negotiation and starting WTO system. Under the drastic changes of rice economic settings as price decrease of rice and downward decrease of farm income, Korean and Japanese farmers might have lost their intention to grow rice in paddy fields without the direct payment system to compensate rice income decrease. To adapt the direct payment system, the total public value of multi-function of paddy should be identified in terms of money. According to the research results, the total value of multi-functional value of paddy in Korea were estimated 21,596thousand won which is higher than rice production value by 2.1 times. On the other hand the total value of Japanese paddy were amounted to 21,390 Yen which is more than that of Korea by 10times outstandingly. Likewise Japanese have evaluated the paddy field very important enterprise from the view point of food security and multi -functions of paddy to their socio-economic life and environmental sustainability in Japan.

This study was conducted to identify dietitians' position and role by assessing the present condition on management of human resources in contracted foodservice management company. Questionnaires were distributed to 79 contracted companies (eight large-size, 48 mid-size, 23 small-size companies) from March to May in 2002. Statistical analysis was performed with SPSSwin (version 8.0). The data were analyzed in group comparisons using frequencies and percentage for every item in the questionnaires, $x^2$-test, and oneway ANOVA. About eighty-five percent of contracted foodservice companies employed the new dietitians as full time employees, and seventy-five percent of them were promoted the dietitians by evaluation after a given period of time. As a starting payment for university graduates, large-size companies payed an average of 16,260,000 won/year, which was significantly higher (p<0.01) than those of mid-sized (11,320,000 won/year) and small-sized companies (11,620,000 won/year). The mean lengths of dietitians' service were 33.5 months in large-size companies, 26.5 months in mid-sized companies, 26.0 months in small-sized companies. It was less than 3 years in all companies (avg. 26.9 months). Fifty-four companies (68.4%) employed dietitians in each foodservice contract, whereas 25 companies didn't employ dietitians. The ratios of dietitians out of employees in each department of the companies were 42.6% in the department of contracted foodservice management, 19.9% in the department of menu development, 18.1% in the department of food safety, 8.7% in the department of distribution and purchase, 4.2% in the department of business, and 3.9% in the department of customer satisfaction. The dietitians' positions were directors in two companies (2.5%), general managers in two companies (2.5%), deputy managers in seven companies (8.9%), managers in twenty-nine companies (36.7%), assistant managers/chief clerks in twenty-four companies (30.4%), and chiefs in twenty-five companies (31.6%). The frequencies of training for dietitians were 6.2 times/year for the food safety training, 5.8 times/year for the cooking training, 4.8 times/year for nutrition-related training, and 4.7 times/year for service training.

Trust-based solutions provide some form of payment to peers to encourage good behavior. The problem with trust management systems is that they require prior knowledge to work. In other words, peers are vulnerable to attack if they do not have knowledge or correct knowledge of other peers in a trust management system. Therefore, considering only trust is inadequate when a decision is made to identify the best set of peers to utilize. In order to solve the problem, we propose a distributed decision-making mechanism for wireless peer-to-peer (P2P) networks based on game theory and relevant trust mechanisms in which we incorporate the element of trust and risk into a single model. The main idea of our mechanism is to use utility function to express the relationship between benefits and costs of peers, and then make the decision based on expected utility as well as risk attitude in a fully distributed fashion. The unique feature of our mechanism is that it not only helps a peer to select its partners, but also mitigates vulnerabilities in trust-based mechanisms. Through analysis and experiments, we believe our approach is useful for peers to make the decision regarding who to interact with. In addition, it is also a good starting point for exploring tradeoffs among risk, trust and utility.

With the development of technology and media and the pursuit of non-face-to-face due to the corona pandemic, the influence of live commerce, a real-time streaming shopping channel, is growing. Starting from China, the popularity of live commerce is growing all over the world, and it has become an interesting topic among many practitioners and researchers. However, compared to its popularity, there are few studies on live commerce. Therefore, we build a theoretical model in terms of IT affordance such as visibility, guidance shopping, trading, and meta-voicing and investigate how live commerce affects engagement with customers. We empirically measure 428 individuals who have used live commerce using survey data. In addition, we conduct four types of scenario experiments on whether social cues on exposures of other consumers, influence customer engagement. Our results show that trading affordance has the most significant effect. This shows that the live commerce platform may want to devise a program that helps make payment easier for users who prefer a quick and simple process. Our study contributes to the literature by presenting the importance of IT affordance for live commerce.
