통계적 생명가치는 환경정책의 편익 산정에 있어 매우 중요한 역할을 한다. 예를 들어 대기오염물질의 감소에 따른 건강 편익의 최종적인 화폐가치화 단위로 활용되며 이는 비용편익 분석의 기초가 된다. 통계적 생명가치는 사망위험 감소를 위해 사회의 구성원이 지불하고자 하는 화폐적 가치로 정의될 수 있다 따라서 통계적 생명가치는 각 사회를 구성하고 있는 구성원의 특성에 따라 결정된다. 본 연구는 웹 설문조사를 통해 수집된 총 3,081명의 응답자를 질문의 형태에 따라 두 개의 표본으로 분리하여 선택실험법을 적용하였다. 추정결과 총 1,528명의 표본 집단의 자료를 통해 도출된 약 13억 원의 통계적 생명가치가 가장 적절한 것으로 나타났으며, 이는 국내 선행연구를 활용한 메타분석의 결과와 유사하다. 또한 응답자들은 사망위험을 감소시키기 위해 정부의 정책비용에 대한 지불보다는 개인 차원의 예방에 비용을 지불하는 것을 선호하는 것으로 나타났다.

Purpose - This study empirically analyzes the consumer value of risk management associated with illegal, unreported, and unregulated (IUU) fishing of fishery products imported to Korea. The global regulatory paradigm for IUU fishing has shifted from production-centered to market-centered. As a result, changes in the international fisheries trade environment emphasizing "transparency" and "legality" of the production process are accelerating. Therefore, changes in the management systems of fishery products entering the country are also needed. Accordingly, this study estimated the consumer value for risk management of IUU fishing, targeting major fish species imported to Korea, and derived the feasibility of introducing related policies. Design/methodology - This study used the choice experiment as an analysis model to estimate consumers' willingness to pay for the "possibility to check for IUU fishing." The choice experiment assumes that the value of a good or service is composed of separable attributes and that the sum of the part-worth of these individual attributes becomes the total value. In this study, respondents were presented with profiles comprising three attributes (country of origin, price, and possibility of checking IUU fishing) and the levels of frozen poulp squid, the subject of the analysis. The participants were asked to select their preferred profile. The marginal willingness to pay for each attribute was derived from the results of the respondents' choices using conditional logit model estimates. Findings - There is a marked difference in utility based on the preference of the country of origin of fishery products among consumers. In addition, the utility of fishery products that have undergone IUU fishing verification was observed to be higher, with the utility marked to be higher for lower prices. Originality/value - Estimating the policy value of the risk management in IUU fishing of imported fisheries products in this study is a novel attempt that has never been conducted before. Several studies have been conducted to assess the risk of IUU fishing associated with the import of fishery products internationally. However, such studies are yet to be conducted in Korea. Instead, policies and studies have focused on issues related to complying with trading partners' legal and transparent standards for exporting fishery products. This study should be the beginning of more in-depth empirical and theoretical explorations to establish order in the domestic seafood market and respond to changes in international regulations on IUU fishing.

An experiment was carried out with village chicken at the laying stage raised on the semi-intensive system on three feeding treatments with each of 30 birds replicated three times. The three feeding treatments were: layer mash only, layer mash and corn as choices and choices of a high protein concentrate and corn. Feed and protein intake was significantly higher for birds on the layer mash and lower for birds on the choices of a high protein and corn diet. There was no differences in egg production for the birds fed the layer mash either alone or a choice with corn but lower for the birds on the choices of a high protein feed and corn. There was no differences in egg weight and gross efficiency for all treatments. The practice of choice feeding layer mash and corn could be adopted by farmers rearing village chicken under the semi-intensive system due to the lower cost.

The experiment was conducted to study the effect of choice feeding on growth performance, carcass quality, gastrointestinal development and feed utilization of 22-49 days old broilers. One hundred and forty four 22-day-old broilers were randomly allocated to 3 treatments with 4 replicates per treatment and 12 birds per replicate. Three feeding regimes are complete diet (control), ground corn and protein concentrate (treatment I), and soybean meal and balancer (treatment II). Protein concentrate is the residue part of complete diet without corn, and balancer is the residue part of complete diet without soybean meal. Treatment I and II are designed for the broilers to freely choose the two parts of diet. The results showed that: (1) broilers under choice feeding (treatment I and II) had lower performances compared with the control; (2) gastrointestinal development and the efficiency ratios that broilers converted dietary crude protein and lysine to body weight gain were improved in treatment I (p<0.05); (3) there were no significant differences in the apparent metabolizabilities of dietary dry matter, crude protein and gross energy, and deposition ratios of dietary nitrogen and energy, and carcass quality among three feeding regimes (p>0.05).

본 연구는 점포간의 유사성이 존재하는 경우 소비자의 점포 선택문제를 다루었다. 기존 IIA모형은 점포간 유사성을 고려하지 않기 때문에 유사한 서비스를 제공하는 점포간의 경쟁관계를 정확히 파악할 수가 없었다. 본 연구에서는 기존의 로짓모형에 대안간의 교차효과(cross-effect)를 포함함으로써 경쟁관계를 파악할 수 있는 mother 로짓모형을 활용하였다. 모형의 입력자료는 컨조인트와 같은 실험설계를 사용하여 구성된 선택세트중 선호하는 점포를 선택하게 하여 수집하였다. 적용 사례로 서울의 한 지역에 신규점포가 진입하는 가상적 상황을 설정하고 mother 로짓모형을 이용하여 소비자의 패스트푸드점 선택행위을 분석하였다. 분석결과 점포간 교차효과가 유의한 것으로 나타나 IIA가정은 기각되었고 mother 로짓모형의 예측력이 IIA모형보다 높은 것으로 나타났다. 본 연구에서 제안한 mother 로짓모형은 IIA의 한계점을 극복할 수 있다는 장점과 더불어 대안간의 cannibalization상황을 파악할 수 있기 때문에 점포 선택문제 뿐 아니라 상표선택의 시장구조분석에서도 유용하게 이용될 수 있을 것이다.

Purpose: This paper aims to investigate the influence of different methods of distributing sweepstakes (i.e., whether consumers choose to enter into the sweepstakes themselves or they are given the sweepstake ticket by default) on the effectiveness of the sweepstakes promotion (i.e., interest in the sweepstakes and intention to participate in the sweepstakes). Research design, data and methodology: The paper verifies this effect through three experimental studies: an online experiment using a sweepstakes promotion scenario at a department store, an online SNS sweepstakes promotion event, and a face-to-face card lottery game. Results: Participants belonging the group that chose sweepstakes tickets by themselves showed higher interest and intention to participate in the sweepstakes than those who were given the sweepstakes ticket by default. Furthermore, the group that chose the sweepstakes card thought it had a higher probability of winning than the group given the sweepstakes card. Conclusions: This paper shows a way to enhance the promotional effect of sweepstakes in the retail stores, without incurring additional costs, by approaching from sweepstakes design from the psychological perspective of the consumer. The study also sheds new light on the effect of sense of control manipulation using choice behavior in the promotional context.

This study investigated the influence of the application of the career education programs related to the science of the elementary school on the career choice. For this study, a total of 32 lessons (4 units) utilizing the career education programs related the science curriculum were developed. The study subjects were 128 students from Y elementary school located in Incheon. A test with regard to the science related career choice and the science related career choice factors was performed before and after the lessons. For more detailed analysis, the experimental group was divided into two groups of female and male students; students who hope and do not hope career in science-related fields. As a result of the performance of career education programs, it showed a significant improvement in the 'science related career choice'. And, it also showed all significant improvements in 'science related major/department, education lecture selection'. It was possible to know that the students who do not wish science related jobs in the future also changed their mind on to the science. In addition, all the subcategories of the 'preference for science learning' area such as 'preference for science subject', 'preference for experiment', 'recognition of science subject availability', 'recognition of the impact of teacher' showed a significant improvement. The 'perception about career related to science' showed a significant improvement on the whole. There was no significant improvement on the whole in 'participation in science related activities'.

Ziperol, anti-tussive, is considerably bitter. Therefore, it is necessary to mitigate the bitterness in ziperol syrup for children. In this experiment, it was attempted to mitigate the bitterness of zipeprol by means of polymers such as $\beta$-cyclodextrin, arabic gum, HPMC(hydroxypropyl methylcellulose), PEG 2000(polyethyleneglycol 2000), PVP(polyvinylpyrrolidone). Caffeine was used as the reference standard of bitterness. In the result of this experiment, $\beta$-cyclodextrin, would mitigate the bitterness of zipeprol more largely than any other polymers. Arabic gum was the second choice which would mitigate the bitterness of zipeprol.
