Purpose Co-creation is a form of collaboration to create joint values with participation of diverse interested parties. It has been introduced by large companies at an early stage and due to changes in management environment, the scope of its concept has been expanding to the SMM(Small and Medium Manufactures). The objective of this study is to examine the impact of Co-creation on SMM's non-financial and financial performance. Design/methodology/approach Based on literature review, the research model was developed. To test this research model, we collected 188 questionnaires with SMM which utilized Co-creation and supplied parts to the companies. The t-test and ANOVA were employed for the analysis of data Findings The research result showed that the difference in business performance between the groups with much use of Co-creation and those with little use of Co-creation, there was significant difference in both non-financial and financial performance. In addition, non-financial and financial performance were different among four implementation behavior of Co-creation including Common value, Information share, Risk benefit, and Mutual benefit.

The main purpose of this study is to analyse economic feasibility of low-carbon-oriented gear for anchovy boat seine. The results of benefit/cost analysis showed that use of the low-carbon fishing gear is economically feasible. Considering the fuel saving and relatively low $CO_2$ emission by reducing the resistance of gear, net present value by such type 1 gear improvement was estimated about -2,490 ~ -1,580 million won with the benefit-cost ratio 0.81~ 0.88. And net present value by such type 2 gear improvement was estimated about 6,540 ~ 7,780 million won with the benefit-cost ratio 1.79 ~ 1.94. Development of lowcarbon trawl gear would render significant contributions to reducing $CO_2$ emission in fishing operations and lead to reduce fishing costs due to fuel savings.

Korea Electrical Safety Cooperation(KESCO) have provided the electrical safety speed-call service from 2007 year. Purpose of the service is to reduce discomfort of electricity use and to prevent electrical accident like as electrical fire and shock accident by providing emergency treatment service on fault of the residential electrical facilities notified in the specific house like as a lower-income group and a social welfare facility. But efficiency and economic evaluation of the electrical safety speed-call service is impossible because analysis on the quantitative effect of the service is difficult. This paper presents cost-benefit analysis method and result of the electrical safety speed-call service. The presented cost-benefit analysis method has a two-step process: the first step is to measure quantitative electrical fire prevention effect of the service by using electrical accident statistics and developing outcome analysis logic model of the service effect, and the second step is to analysis cost-benefit(B/C)of the service by calculating quantitative benefit analysis on the measured quantitative electrical fire prevention effect. The results showed that cost-benefit(B/C)of the electrical safety speed-call service is over 4 after 2010 year.

국내 건설산업의 경우 전통적으로 원도급업체와 하도급업체의 관계를 수직적, 종속적 관계로 인식하고 있는 실정이다. 이러한 문제점을 개선하기 위해서는 원${\cdot}$하도급업체를 동반자로 인식하고 상생협력과 발전을 모색할 수 있는 새로운 건설 환경을 조성하여야 할 것이다. 이를 위하여 원${\cdot}$하도급업체간의 상생협력을 위한 성과공유제를 적용하기 위해서는 건설 생산방식과 생산조직 등의 특수성을 반영할 수 있는 적용방안을 제시할 수 있어야 할 것이다. 다라서 본 연구는 건설산업에서 성과공유제의 적용 현황 및 문제점을 조사하여 건설산업에 성과공유제 적용을 위한 기초적인 자료제공을 연구의 목적으로 한다.

Purpose: The use of flumazenil administration in the emergency department is still controversial because of concerns about adverse effects. The present study was conducted to re-evaluate the risk-benefit ratio associated with flumazenil administration to patients suspected of having acute hypnotics and sedatives poisoning in the emergency department. Methods: A retrospective chart review study was conducted for patients whose final diagnoses were "poisoning" and "benzodiazepine" or "sedatives-hypnotics" from Mar. 2006 to Feb. 2015. The basal characteristics of the patients, including past medical history, ingredients and dose of ingested drug and co-ingested drugs were investigated. For patients administered flumazenil, responsiveness and time from admission to flumazenil administration were investigated with supplement. All collected data were analyzed in aspect terms of risk/benefit. Results: A total of 678 patients were included in our study. Benzodiazepine was the most common sedative/hypnotic drug prescribed, and the frequency of prescription continuously increased. The proportion of TCA as co-ingestion decreased from 13.1% to 3.9% in patients with acute sedative/hypnotic poisoning. Flumazenil was administered to 55 patients (8.1%), of which 29 patients (52.7%) were applied to contraindications. Fifty-three patients (96.4%) showed positive responsiveness, including partial responsiveness after flumazenil administration. No severe adverse events were identified. Conclusion: Based on the current trends in prescription patterns for sedative/hypnotic drugs, increased use of non-TCA antidepressants, and responsiveness to administration of flumazenil, benefit seemed weighted more in this study, although the observed benefits were based on limited results. Further prospective multicenter studies will be needed to optimize benefit-risk ratio.

본 연구에서는 건조 하수슬러지의 화석연료와의 혼소 가능성 평가를 연소특성, 경제적 이익 2가지 관점에서 평가하였다. 공업분석 결과 A하수처리장의 건조 하수슬러지의 휘발분은 36.48%, B하수처리장은 40.10%로 석탄에 비해 매우 높았으며, 연료비는 0.12, 0.14로 매우 낮아 연료로써의 품질은 낮은 것으로 조사되었다. 특히 연소성 지수가 30,000kcal/kg 이상으로 연료의 기준인 3,000~5,000kcal/kg을 크게 초과하여 건조 하수슬러지의 개질이 필요할 것으로 판단된다. 건조 하수슬러지의 경제성 평가 결과 석탄의 절감에 따른 이익은 연간 73.4억원, REC인증 이익은 56.4억원이 발생하는 것으로 산정되었다. 반면에 회분처리비용 증가에 따른 손실은 2.6억원, 건조 하수슬러지의 혼소에 소요되는 설비의 투자 및 운영비가 4.2억원으로 산정되어 건조 하수슬러지의 혼소에 따른 경제적 이익은 연간 123억원으로 추산되었다. 다만, 건조 하수슬러지의 생산에 소요되는 동력 및 건조 하수슬러지의 혼소로 인한 환경오염 등에 대한 비용은 본 연구에서 고려되지 못하였으며 향후 이에 대한 연구가 추가적으로 필요할 것이다.
