The purpose of this study is to estimate the utility value of boat fishing experience marine tourism activity in Jeju Island’s Chagwido. The utility value is estimated by single bounded and double-bounded dichotomous choice contingent valuation method. The contingent valuation method is used to estimate economic values for all kinds of coastal ecosystem services. The method involves directly asking people, in a survey, how much they would be willing to pay for specific environmental services. So, the method has great flexibility, allowing valuation of a wider variety of non-market goods and services than is possible with any other non-market valuation technique. This study collects the effective 504 questionnaires from boat fishing experience tourists in Jeju Island’s Chagwido. The results show that the average willingness to pay amount(WTP) is estimated to be about 17,000 Korea won by single bounded and double-bounded dichotomous choice contingent valuation method. This indicates that the utility value of boat fishing experience marine tourism activity is estimated to be about 17,000 Korea won in Jeju Island’s Chagwido.

온실에서 재배되는 어윈 망고는 그 수관이 복잡하여 생육을 정확하게 진단할 수 있는 생육 지표 결정이 어렵다. 엽면적, 엽생체중과 엽건물중은 생육을 진단할 수 있는 지표이며, 이를 비파괴적으로 추정할 수 있는 모델 확립이 필요하다. 본 연구의 목표는 어윈 망고 (Mangifera indica L. cv. Irwin)의 엽장, 엽폭, 엽병장, SPAD 값 등의 비파괴적 생육지표를 이용하여 엽면적, 엽생체중과 엽건물중을 추정하는 모델을 확립하는 것이다. 6년생 어윈 망고의 성엽에 대하여 엽장, 엽폭, 엽병장과 SPAD 값을 측정하였으며, 이에 따른 엽면적, 엽생체중과 엽건물중을 측정하였다. 기존에 사용되는 모델식 중에서 14종의 모델을 선정하였으며, 회귀분석을 통해 각 모델의 계수를 추정하였다. 이중에서 높은 R2 과 낮은 평균제곱근오차 값을 보이는 세 모델식에 대하여 검증한 결과, R2 값은 각각 0.967과 0.743, 0.567로 나타나 신뢰성이 있다고 판단되었다. 이러한 방법은 작물의 생육 지표로 편리하게 추정하는데 도움을 줄 수 있다.

본 연구는 현대 조직에서 조직구성원의 직무태도와 행동에 영향을 미치는 가장 중요한 요인 중 하나인 상사신뢰가 조직구성원의 직무만족과 이직의도에 미치는 영향과 그 메커니즘을 확인하였다. 먼저, 상사신 뢰와 직무태도에 대한 선행연구를 바탕으로 상사신뢰가 직무만족 및 이직의도에 미치는 영향을 상대적으 로 직업적 안정성이 보장된 지방자치단체 공무원을 대상으로 검증함으로써 상사신뢰의 효과에 대한 외적 타당도를 확대하고자 하였다. 보다 중요하게도, 상사신뢰가 조직구성원의 직무만족과 이직의도에 미치는 영향력 관계의 메커니즘에 대한 이해를 확대하기 위하여 일가치감의 매개효과와 조직정치지각의 조절효 과를 검증하였다. 지방자치단체 공무원 총 260명을 대상으로 2회에 걸쳐 수집된 설문자료를 분석한 결과, 상사신뢰는 직무만족과 정(+)의 관계를, 이직의도와는 부(-)의 관계를 보였다. 또한 일가치감은 상사신뢰와 정(+)의 관계가 있고, 직무만족과는 정(+)의 관계, 이직의도와는 부(-)의 관계가 있었으며, 상사신뢰와 직무태도와의 관계를 매개함이 확인되었다. 조직정치지각은 상사신뢰와 일가치감의 관계를 조절하였는 데, 조직정치지각의 수준이 높을 때보다 낮을 때 상사신뢰가 일가치감에 미치는 영향이 더 강하게 나타남 이 확인되었다. 뿐만 아니라, 상사신뢰가 일가치감을 매개로 조직구성원의 직무태도에 미치는 간접효과에 대해서도 조직정치지각의 조절효과가 확인되었다. 이러한 연구 결과를 토대로 본 연구의 시사점, 제한점 및 추후 연구과제에 대해 논의하였다.

Yield-per-recruit (YPR) analysis is used to provide management guidance for the efficient use of a fish cohort. However, the individual fish price per unit weight of small yellow croaker (Larimichthys polyactis) or hairtail (Trichiurus lepturus) increases dramatically by size in Korea. Therefore, age-based production value-per-recruit (PPR) analysis has recently been developed (Zhang et al., 2014). Since age determination requires a substantial amount of money and time and it is even impossible for some fish species, it is difficult to obtain age information to apply the age-based PPR model. Thus, we attempted to develop an alternative method, which uses length data rather than age information, called the length-based PPR analysis. The results revealed that length-based PPR analysis was much more conservative for stock management than the YPR analysis. Furthermore, the PPR analysis was more economically beneficial than the YPR analysis, which can prevent the fish stock from the economic overfishing. In conclusion, the length-based PPR analysis could be a proper approach for stock assessment in the case that the individual fish price per unit weight increases dramatically by size, and this analysis is useful to obtain vital management parameters under data-deficient situation when traditional stock assessment methods are not applicable.

It was confirmed that the extreme value distribution model applies to probability of exceeding more than once a day monthly the facility capacities using data of daily maximum inflow rate for 7 wastewater treatment plant. The result of applying the extreme value model, A, D, E wastewater treatment plant has a problem compared to B, C, F, G wastewater treatment plant. but all the wastewater treatment plant has a problem except C, F wastewater treatment plant based 80% of facility capacity. In conclusion, if you make a standard in statistical aspects probability exceeding more than once a day monthly can be ‘exceed day is less than a few times annually’ or ‘probability of exceeding more than once a day monthly is less than what percent’.

This study contributes to the limited literature on the innovative pricing method of Pay-What-You-Want (PWYW) in the context of a high-value service. PWYW is a participative pricing approach that takes away all the power from the seller allowing customers to decide what price they want to pay. As such, the customer is free to set any price (even zero) and the seller has to accept it (Kim et al., 2009). Existing research on PWYW examines the impact on customers fairness perception (Haws et al., 2006), willingness to pay (Spann et al., 2004), and purchase intentions (Chandran et al., 2005). Studies also provide insights into which factors (e.g., price or value consciousness) impact on the PWYW price people pay, and on its profitability (Kim et al., 2009). PWYW is more effective than traditional pricing approaches for services that follow an economy pricing strategy (Schons et al., 2014) but not for luxury goods (Balan, 2014). A notable omission in the literature is the lack of studies that directly compare the profitability of PWYW for potential, new, and repeat customers in a high-value priced service setting. The high-value strategy is defined as positioning a high quality service sold at a medium price (Kotler et al., 2001). Another lack in literature is the use of natural experiments to examine whether groups of customers will pay different prices in comparison to traditional price setting methods. In marketing research, natural experiments have been used to examine price-quality trade-offs with the conclusion that consumers pay more for better quality (Bertini et al., 2012). Using the natural experiment of the biggest dance festival in Europe (ImPlusTanz) where different customer groups pay different prices, the study compares the applicability and profitability of the PWYW pricing method. Specifically, the minimum, maximum, and PWYW prices are compared to traditionally set prices. Results from the secondary data analysis reveal that ImPulsTanz uses a pricing structure based on demographics mainly. Survey results show that the PWYW prices differ between three natural customer groups. Repeat customers are prepared to pay the highest prices compared to new and potential customers. Despite all customers indicating they will pay for the service generally, PWYW prices paid are lower than traditional list prices from the secondary data analysis. Findings also confirm differences between customers with diverse price perception/consciousness, perceived quality and value of the services offered.

Despite the consumer's interest in sustainable fashion and the sustainable fashion phenomenon in the fashion business being a serious issue for our society, only a limited number of studies focus on investigating the consumer's perceived value of sustainable fashion. Although eco-friendly consumption has been recognized as one of the major concerns of the fashion business, environmentally prudent consumption has not yet transformed into purchasing behavior. However, fashion companies try to offer many seasonal collections due to the fast fashion trends to meet the consumer's needs. Such trends have brought about an enormous amount of apparel waste, negative environmental impacts and serious questions about social issues. In addition, today’s fashion consumers appear to have a narrow point of view on sustainable/green fashion that focuses mainly on organic clothing, and avoids or shows no interest in the wider scope of sustainability encompassing environmental, social and economic concerns (Cervellon, Hjerth, Richard, & Carey, 2010). Increasing the consumption of sustainable fashion necessitates research into how fashion consumers make purchasing decisions. Therefore, the information and value of sustainable fashion need to be diffused by fashion consumers. Hethom and Ulasewicz (2008) stated that the consumer acts as a major stakeholder with the greatest impact on the development of a sustainable industry. Furthermore, it is necessary to examine the consumer's purchase decision-making process for sustainable fashion products in academia. According to previous studies, the awareness of sustainability issues is also growing due to the environmental impacts. However, this awareness has not yet affected apparel purchasing behavior and actual purchasing (Kim & Damhorst, 1998). In order to affect the behavior of fashion consumers and expand sustainable fashion in today's marketplace, it is essential to identify the influencing factors in purchase decision-making process for sustainable fashion products.

This study (i) examines the main effect of how a customer’s trust in the service personnel could affect his/her service co-designing and co-delivering behavior; and (ii) investigates how the main effect could vary by the customer’s trust in the service brand, and the types of customer contact service contexts. Keywords: customer participation, co-

This study aims to examine the impact of perceived usefulness, perceived ease of use, site appearance, informativeness and perceived risk on online brand equity though the brand value chain. The study grounds from two theories: TAM and Perceived value approaches. Five hundred and six sets of questionnaires were used to analyze and produce the research results. The study found that perceived ease of use and informativeness were not related to the customer’s perceived functional value and emotional value on the brand while other factors were significantly related. The results of the study were discussed as well as the research conclusion and recommendations
