This study focuses on social norms and perceived benefits that are expected to lead to purchase fashion goods selling by social enterprises that can help guide the establishment of effective sales strategies for social enterprises. The relationships among two social norms (injunctive norms and descriptive norms), three perceived benefits (cause benefits, psychological benefits, and social image benefits), and purchase intention were investigated respectively. Data were collected via an online web survey and 11 hypotheses were statistically tested by using PLS-SEM analysis. Purchase intention toward the fashion products of social enterprises was influenced by four antecedent variables (injunctive and descriptive norms, cause and psychological benefits) excluding only social image benefits. However, descriptive norms only affected psychological benefits while injunctive norms only affected social image benefits. The findings suggest that the owners or marketers of social enterprises need to create a social atmosphere in which more consumers buy the fashion goods for social enterprises and emphasize consumers' psychological benefits that they feel mentally more comfortable by purchasing the fashion goods of social enterprises.

In the management of colo-retal and anal cancer, accurate staging, treatment evaluation, early detection of recurrence are main clinical problems. F-18 FDG PET (PET/CT) has been reported as useful in the management of colo-rectal and anal cancer because that PET has high diagnostic performance comparing to conventional studies. In case of liver metastases, for confirmation of no extrahepatic metastases, in case of high risk of metastasis, for avoiding unnecessary operation, PET (PET/CT) is expected more useful. In anal cancer, PET is expected useful in lymph node staging. For the early prediction of chemotherapy or radiation therapy effect PET has been reported as useful, also. In early detection of recurrence by PET, cost-benefit advantages has been suggested, also. PET/CT is expected to have higher diagnostic performance than PET alone.

As a central part in smart construction, BIM has been rapidly spread in construction industry at large. However, the level of applying BIM in construction stage is still relatively lower than that in design stage due to unclear application method, inadequate design BIM model, technical faults of BIM itself, etc. Under these circumstances, public owners inevitably need to adjust the scope and pace in BIM application considering their internal support and capabilities of contractors. This study aims to suggest major BIM-applicable tasks during construction stage in the process of establishing gradual long-term and short-term introduction strategy for public apartment housing projects. Those major tasks were identified with the combination of the importance of tasks and the future benefits of BIM using IPA method. To do so, the degrees of contribution to achieving objectives in construction, current task execution, and communication requirement were investigated by internal site managers. On the other hand, the expected benefits and current level of using BIM were assessed by BIM experts. Among operational tasks by phases, design review, construction plan review, making as-built drawing, etc. were categorized as major tasks. In addition, progress control, regular meeting, master schedule development, work inspection, on-site quality check, etc. were also drawn as major tasks by management areas. The results of this study will provide the useful reference for owners concerned about the introduction of new technologies.

In most manufacturing systems, all customers are expected to take deliveries from inventory. However, in some situations, management may keep inventory only for some customers and not keep inventory for the others. The reason is that they would like to make as much benefit as possible from the first group of customers and this may help sell these customers on further products. This paper attempts to determine the cutoff between the group of customers who are given products immediately when their orders come and other customers who will be served but have to wait for the production of their products. The optimum set of customers to be served immediately and the optimum set of customers who have to wait for the production are found using linear programming to optimize perceived manufacturer benefits measured as the product of the benefit factor and the corresponding profit per customer. The results indicate that it is not necessarily wise to keep inventory for all customers.

This paper deals with a evaluation algorithm of interruption cost in distribution systems in the case where Dispersed Storage and Generation (DSG) systems are interconnected with the distribution systems. If DSG systems are operated as the function of the load levelling in distribution systems at the normal conditions and as the uninterruptible power supply in fault areas at the emergency conditions, the reliability improvement of the distribution systems can be expected. In other words, the benefit can be represented by the cost avoiding interruption according to the operation of DSG systems when a fault is occurred. Therefore, this paper presents the evaluation algorithm for interruption cost in order to evaluate the benefit for the uninterruptible power supply of DSG systems in a quantitative manner.

This paper conducted an analysis of economic effects of offshore wind power in Korea with benefit/cost analysis. The existing feed-on tariff, which was too low to support wind power development, was recently replaced with a Renewable Portfolio Standard(RPS), effective from 2012. According to the new regulatory policy, The Korean government has announced a strategy to draw investments worth for offshore wind farms with a total capacity of 2.5 GW over the next eight years, which is expected the change of cost and benefit. After overview the offshore wind power development status, The effects on cost can be divided by economic, environmental and social factors. Each factor will be calculated and combined by both evaluating index and using Quantification methods. At the end, the implication for the evaluation of feasibility of offshore wind power of Korea will be done.

New transport technologies have been rapidly developed and various transport systems are ready to introduce. However, there no exists effective decision making tools for pre-feasibility studies on transport systems. The pre-feasibility studies should provide reliable solutions about whether a certain transport system is feasible or not by cost-benefit analysis and effectiveness test of enhancing regional economy. This study introduces the smart transport investment/information system (SMARTIS) for supporting decision making with ease, fast and reliable methods. The SMARTIS incorporates travel demand estimates into the process of feasibility studies with automatic data processing methods to give reliable solutions quickly. The SMARTIS is expected to be informative for transit agencies, planners, and operators.

이 연구는 상수도수불화사업의 경제적 편익에 미치는 영향을 파악하기 위하여 2003년 1월 1일부터 6월말까지 상수도수불화지역인 청주시 상당구, 상수도수비불화지역인 안양시 만안구를 대상지역으로하여, 조사대상지역내의 치과의원에서 진료를 받은 진료지표를 비교 분석한 결과는 다음과 같다. 1. 상수도수비불화사업지역인 안양에서 상수도수불화사업을 실시할 경우 2003년 상반기의 6세에서 18세까지 연령에서 기대되는 치아우식증과 치수 및 치근단 주위조직 질환으로 인한 감소기대진료건수는 1,272건, 저추정시 636건, 고추정시 1,908건이 감소될 것으로 기대된다. 그리고 감소기대진료비는 40,888천원, 저추정시 20,444천원, 고추정시 61,333천원이 감소될 것으로 기대된다. 2. 상수도수불화사업의 전국 확대를 가정한 연간 기대건수는 2,492,018건, 저추정시 1,246,009건, 고추정시 3,738,027건이 감소가 기대되며, 감소기대진료비는 80,105,075천원, 저추정시 40,052,537천원, 고추정시 120,157,612천원이 각각 감소가 기대된다. 3. 급수인원이 48,925명인 영운정수장의 경우 편익/비용 비율이 2.9배이며, 급수인원이 239,751명인 지북정수장의 경우 편익/비용 비율이 9.0배이다. 상수도수불화사업은 급수인원이 증가함에 따라 비용의 증가는 미미하고 규모에 따른 경제 효과가 매우 크게 나타났다. 국민구강건강증진은 아울러 구강건강보험재정의 비용절감과 연관이 있다고 사료되며, 이를 위하여 전국 모든 지역에 상수도수사용을 확대 실시하여, 상수도수와 불소화에 대한 적극적인 홍보와 교육을 통한 신뢰 구축이 추가적으로 필요하다고 생각된다.

소비자와의 장기적 관계 관리가 강조되는 현 시점에서, 소비자들이 인터넷 쇼핑몰에서 의류제품을 구매할 때 지각하는 관계혜택에 초점을 두고, 소비자들의 관계혜택지각이 쇼핑몰에 대한 관계몰입 및 충성도에 미치는 영향을 규명하고자 하였다. 본 연구를 위해 인터넷 의류구매 경험이 있는 20대 및 30대 남녀 소비자 343명에게 설문조사하였다. 연구결과, 인터넷 의류구매에서의 관계혜택지각은 쇼핑몰에 대한 관계몰입 및 충성도에 유의한 영향을 미쳐, 관계혜택지각이 클수록 쇼핑몰에 대한 관계몰입 및 충성도가 높은 것으로 나타났다. 또한 관계혜택지각 차원에 따라 소비자들을 유형화한 결과, 소비자들은 '사회적 혜택지각 집단', 경제/쇼핑편이성 혜택지각 집단', '쇼핑편이성 혜택지각 집단', '고객화 혜택지각 집단', '정보적 혜택지각 집단', '심리적 혜택지각 집단'으로 구분되었으며, 이들의 쇼핑몰에 대한 관계몰입 및 충성도에도 유의한 차이가 있는 것으로 나타났다. 본 연구는 인터넷 기업이 고객과의 관계를 결속시키고 나아가 쇼핑몰에 대한 충성도를 높이는데 도움을 줄 수 있을 것으로 본다.

좌석 안전띠는 자동차 안전장치 중 차량의 안전상 가장 중요하고 효과적인 장치로 알려져 왔다. 우리나라의 경우 운해중 안전띠의 착용률, 특히 뒷좌석의 착용률이 낮다. 최근 조사 자료에 의하면 뒷좌석의 안전띠 착용률은 20%의 수준이다. 최근 좌석 안전띠 미착용 알림장치(Seat Belt Reminder, SBR)를 의무화하는 것을 고려중에 있다. 본 연구는 SBR의 의무화할 경우의 도입효과에 대한 분석이다. 본 연구에서 안전띠 착용효과는 해외의 연구사례(Evans(1991) 모형)를 준용하였다. 주요 변수로 안전띠 초기착용률은 국내 조사자료, SBR로 인한 목표 착용률은 운전자 순응도에 따른 시나리오에 따라 추정하였다. 연구 결과, 좌석안전띠 미착용 경고장치의 운전자 순응비율이 90%이상일 경우 매해 119명의 사망자의 감소효과를 가져올 것이고, 편익비용비가 1.84에 달할 것으로 분석되었다.
