  • The hypothetical nature of stated preferences can lead to a hypothetical bias that might work as a normative pressure, influencing survey responses. This paper aims to test the impact of social desirability bias by comparing economic estimates based on both subjective and objective valuation questions. The case study is about an urban riverine restoration project in Deajeon, South Korea. As valuation methods both contingent valuation and choice experiments were comparatively applied. Based on a nationally representative sample of 1,000 respondents, the test results offered contrasting conclusions between two test approaches. Accroding to the estimation results based on the conventional valuation, the marginal willingness to pay estimates are 10,500 KRW from CV; and 18,600 KRW for improving water quality, 2,200 KRW for the inside view, 8,900 KRW for the outside view, and 5,800 KRW for biodiversity from CE. A segmentation-based approach is a conventionally used method, which showed a limited impact of social desirability on willingness to pay estimates. The alternative parameterization-based approach measures a model-wide impact of social desirability, proving a significant bias. Although the study positioned a cheap-talk statement before the valuation section of the survey questionnaires, which might have pre-screened the bias, the overall implications of the results suggest a caution in reducing and observing hypothetical bias. There might remain a significant and substantial hypothetical bias even after cheap-talk, particularly in situations with strong social desirability, so that the potential role of objective valuation questions is guaranteed.

  • This study examined differences in the preference of the fest therapy program regarding stress level. Using convenience sampling method, the surveys on the preferred type of forest healing program and social and psychological stress scales was carried out for adult male and female. As a basis of Psycho social Stress Scale (PWI-SF: Psychosocial Well-being Index Short Form), the adult 620 people were classified such as healthy group, potential stress group, high-risk stress group. The data were analyzed by use of SPSS 21.0 program. To see the difference in preferences for forest therapy program between the three groups according to stress levels, it was analyzed using one-way ANOVA. Depending on the stress levels, there were differences in the preferences of forest healing program such as breathing, breathing exercises, walking in the forest, listening to the sound of water flowing, viewing the forest, counseling, consultation and expert coaching, stress-related lectures, communication-related lectures, forest bathing wind bathing sun bathing. High-risk stress group preferred cognitive based program such as counseling, consultation and expert coaching, stress-related lectures, communication-related lectures. Healthy group appeared to prefer highly emotional approach of the program to take advantage of the five senses such as breathing, breathing exercises, walking in the forest, listening to the sound of water flowing, viewing the forest, forest bathing, wind bathing, sun bathing. Noticeable preference difference was not observed in the potential stress group. It is hoped this study will serve as a basis for the development of forest healing program regarding stress level.

  • 최근들어 Water Security에 대한 관심이 고조되고 있지만 국내의 경우 이에 대한 체계적인 연구가 아직 진행되지 않았고 상수도관망시스템의 오염예방 및 위험관리에 대한 연구는 매우 미비한 실정이며 특히 상수도관망시스템의 위험성 및 취약성에 대한 연구는 전무한 상태이다. 이러한 상수도관망시스템의 위험도와 관련된 여러 위험요소들은 인명의 피해, 재산상의 피해, 환경적 피해, 시스템의 피해 그리고 사회적 불안등 여러 기준을 고려하여 평가되어야 한다. 이 문제는 다기준의사결정(multi-criteria decision making)문제로서 평가기준들(criteria) 간의 상충관계(trade-off)로 인하여 판단이 모호한 대안들을 PROMETHEE(Preference Ranking Organization METHod Enrichment Evaluations) 기법을 이용하여 평가하였다. PROMETHEE는 선호의 유출량(leaving flow)과 유입량(entering flow)의 개념을 이용하여 여러 대안들의 순위선호(outranking)를 산정하는 기법으로, 의사결정자(decision matter)가 비교적 쉽게 이해할 수 있으며 기존의 AHP$\cdot$ANP와는 달리 명확한 판단이 어려운 대안들에 대해서는 비교불가능한(incomparable) 대안으로 분류한다. 이와 같은 위험도 평가결과는 위기상황에 대한 대처방안을 제시할 의사결정시스템 구축의 기초 자료가 될 수 있을 것이다.

  • In this study, the authors examine the ways in which social media ultimately affects the attachment of individuals to their favorite brands. Through an analysis of data using multiple linear regression, this study finds that SNS (social networking site) users that post status updates for a wide audience have no bearing on the individual's use of socialization agents. Those who consume social news passively are, however, likely to depend on socialization agents for determining their final purchase decisions. Socialization agents, both personal and non-personal, also play a role in the formation of brand attachment among individuals who depend on these social sources. Based on these results, marketers are encouraged to establish an online footprint of a social nature to formulate brand awareness and to provide a means for users of social media to improve their brand attachments to their favored brands. As this research was conducted exclusively in the predominantly collective culture of South Korea, further studies could attempt to analyze social networking use and socialization agent use via a cross-culture study, particularly one including an individualistic culture.

  • It is important to consider an equitable allocation framework for domestic GHG emission reduction. First, the study established criteria and indicators for the National Allocation Plan (NAP) based on the principles of cost-efficiency and social-acceptance, and performed a case study of the sectoral effort sharing method, using the effort sharing index. The equity analysis of effort sharing based on sectoral preferences and inter-sectoral equity using a Lorenz Curve are performed. The equitable method is more likely to be suitable than the economic one which considers just reduction potential. Equitable effort sharing reflects a higher level of equity than economic effort sharing. At the same time, the equitable effort sharing method is essential for reflecting equity and establishing criteria for equity because evaluation with the equitable effort sharing method depends in particular on the weight of equity criteria. The result suggests the importance of consideration of equity and the establishment of equity criteria. In conclusion, it is critical to consider not only cost-efficiency but equity in policy decision making in terms of the sectoral effort sharing for national GHG reduction target.

  • 2009년 경찰청 통계자료에 따르면 교통사고 사망자 중 안전 운전 불이행, 중앙선 침범, 신호 위반, 안전거리 미확보 등 운전자의 부주의에 의해 이루어진 사고가 약 90%이상을 차지하고 있어 심각한 사회적 경제적 문제를 초래한다. 이러한 운전자의 운전습관 개선 및 안전운전에 대한 사회적 요구, 사고 기록 등의 요구에 부응하기 위하여, 디지털 주행기록계 차량용 블랙박스 등 다양한 형태의 시스템이 사용되고 있으나, 이러한 시스템은 사고 후 차량데이터를 기반으로 위험운전여부를 분석하여 운전자를 관리하기 때문에 실시간으로 운전자를 관리하기에는 큰 한계가 있다. 이에 본 연구는 3축 가속도 센서와 GPS를 사용하여 위험운전 여부를 판단하고, 그 결과를 계수화하여 운전자의 정숙 운전 지수를 계산하여 보여줌으로써, 안전 운전과 급정차 급출발에 따른 연비 악화를 개선할 수 있도록 한다.

  • This study investigated the relationship between the sociometric status(1) of a target child and the target child's most preferred peer, and (2) of the quality of their friendship between the two peers. Each of the subjects (238 boys, 6, 8, and 10 years of age) nominated 3 preferred peers answered questions about the preferred peers with the use of the Friendship Quality Scales. Results indicated that the sociometric status of children aged 8 and 10 were positively related to that of their most preferred peers. Reciprocal friendships, however, were more frequently observed among children in high sociometric status compared with those in low sociometric status. The quality of friendships among popular children was higher than that of rejected children. The quality of friendships between popular and rejected children was lower than friendship between rejected and rejected children.

  • This study analyzed the influence of social distance and visual information on consumers' fashion style preferences in terms of information characteristics and providers. Data were collected from 521 females in their twenties and thirties who had experience using SNS. The empirical study results were as follows. First, with other factors of exposure under control, the social distance of information characteristics and providers showed a significant impact on fashion style preferences only when social distances were close. Second, the impact of social distance varied depending on the consumer's characteristics. This proved that innovation had significant negative influences, while conformity and informational sensitivity to others showed positive influences on the effects of social distance in terms of information characteristics. Innovation and fashion leadership also showed a negative influence on the social distance effect in terms of information providers. Third, conformity, informational sensitivity to others, and fashion leadership, proved to have a significant impact on the acceptance of eWOM in fashion styles, but innovativeness and normative sensitivity to others did not have a significant influence. This study can be used as baseline data in SNS marketing strategies for vitalizing information spread through eWOM.
