In this paper, the method on calculating benefits of combined heat and power is introduced for standard evaluation in electrical power system. This paper calculates benefits about new national viewpoint and viewpoint of independent power producers and assesses benefits of combined heat and power in Korea and In Seoul national capital area. Benefit costs are composed of avoid cost of centralized generation, line upgrading adjustment, loss adjustment and electrical power trade cost per year in earlier study, in addition trade cost of CO2, construction cost of combined heat and power for accurate calculation. Benefit of combined heat and power is calculated by simulation results of real electrical power system.

Benefit costs are composed of avoid cost of centralized generation, line upgrading adjustment, loss adjustment and electrical power trade cost per year in earlier study, in addition trade cost of $CO_2$, construction cost of combined heat and power for accurate calculation. Benefit of combined heat and power is calculated by simulation results of real electrical power system.

Objective: The Australian Pharmaceutical Benefits Scheme (PBS) is a national drug subsidy program. Given the similarity and comprehensiveness of the Australian PBS and the Korean National Health Insurance (NHI) data, these data are increasingly used for pharmacoepidemiological investigations, as well as international comparative studies. This study aims to introduce the various sources of publicly available PBS data and provide a practical guide to researchers conducting drug utilization studies. Methods: We searched literature and websites to detail and compare the collection, structure, components, and characteristics of each PBS data format. We identified different characteristics of the PBS data from the Korean NHI claims data which are mainly owing to their unique co-payment policies and data collection processes. In addition, the utilization and expenditure of atorvastatin, a widely used treatment for hyperlipidemia, were analyzed using two different sources of PBS data and the different results were interpreted. Results: There exist differences in when data were collected or non-subsidized uses of medicine were included among sources of PBS data. Additionally, two countries have different cost sharing methods inmedicine subsidy scheme; co-payment in Australia and co-insurance in Korea. Therefore, it should be noted that prescriptions under co-payment are not included in some data sources in Australia. Conclusion: Despite several analytical challenges, open access and easy data management are the strengths of the PBS data sources. A detailed knowledge of the PBS data can ensure robust methodology and interpretation of pharmacoepidemiological investigations or international comparative studies.

기업의 신제품 개발과정에서 고객참여는 중요한 전략적 역할을 한다. 본 연구는 고객참여를 고객공동개발 (customer co-development) 과 계약개발 (contract development) 로 구분하고, 고객참여 발표가 기업 가치에 미치는 영향을 이벤트 연구를 통해 분석한다. 바이오 및 제약 산업에 대한 분석을 통해, 본 연구는 계약개발 대비 고객공동 개발이 기업 가치에 미치는 영향은 기업 및 관계 변수에 의해 조절됨을 밝힌다. 특히, 본 연구는 연구개발 협력경험이 많을 때 또는 지분투자를 동반할 때, 고객공동개발이 계약개발에 비해 기업 가치에 양의 영향을 미침을 보여준다.

On July 6, 2021, the Ministry of Education revised and announced the operating regulations of the undergraduate co-op with the aim of protecting students rights and student-centered operation based on mutual benefits for students and institutions. Therefore, the purpose of this study is to analyze universities' perceptions against the amendment of regulation of the Ministry of Education's into universities/college, regions. According to a survey of 75 KACE, we found that colleges are more difficult than universities in terms of administrative work, company participation, reduced opportunities for co-op, and managing participating companies. Next, most of the regional differences in difficulties were not significant, and only the decline in company participation rate was more difficult in Daegyoung/Gangwon/Chungcheong/Jeju than in the metropolitan area. Finally, policy directions such as the differential application of practical support expenses according to the size of the company, tax benefits for institutions, and clarification of the concept of job training were presented.

As a community of practice (CoP) is known to facilitate team learning, it is increasingly important to understand the mechanisms of CoP, thereby enabling organizations to fully utilize it and optimize its benefits. To explain how CoP improves organizational performance, we focus on its effects on social capital and knowledge management activities, and propose a research model suggesting that shared goals and trust in CoP improve its performance through knowledge integration. Our analysis uses structural equation modeling, with field data collected from 372 members of 46 CoPs in three companies; the analysis validates our research model. Our findings also suggest that CoP diversity can strengthen the link between knowledge integration and CoP performance.

Interconnection of electric power systems, as an alternative for energy cooperation under regional economic bloc, has been under extensive debate before progressing the restructure in electric power industry and rapidly expanded in many regions after 1990s. Especially, since northeast asia has strong supplementation in resource, load shape, fuel mix etc., electric power system interconnection in this region may bring considerable economic benefits. In this paper, we evaluate economic benefits from CO2 emission abatement and effectiveness on the fuel mix in Korea by the interconnection in northeast asia. For this analysis, we evaluate effects of CO2 emission abatement under various system interconnection scenarios and compare the results of fuel mix in Korean electric power system with and without transacted electricity via interstate electric power system in northeast asia.
