연예 매니지먼트사와 외주제작사들이 2000년부터 시작된 한류열풍이후 사업다각화 전략을 실행하여 매니지먼트업과 외주제작업 간에 상호겸영을 보편화하는 방식으로 사세를 확장하면서 불공정 거래 등 많은 부작용이 나타났다. 본 연구는 이런 문제에 착안하여 주식시장에 상장한 국내 매니지먼트사와 외주제작사 전체를 상대로 2015년 기준 매니지먼트업과 외주제작업의 겸영 실태를 분석하고, 이해관계자와 전문가들의 심층 인터뷰를 통해 그 대안을 탐색했다. 분석결과 매니지먼트사의 외주제작업 겸영 비중이 평균 32%로 높아 규제가 필요하며, 규제는 수평규제 원칙을 적용하고 미국 법제를 원용한 국내 선행 입법과 연동하여 미국식 규제 모델을 도입하는 게 타당하다는 점을 확인했다. 적용 가능한 규제방안으로는 첫째, 겸영은 허용하되 자사제작 작품에 자사소속 배우의 출연을 금지하는 방안, 둘째, 겸영을 금지하고 지분 10~20% 내에서 상호 투자만 허용하는 방안, 셋째, 상호 겸영과 투자를 전면 금지하는 모델이 제안되었다.

본 연구의 목적은 2010년부터 2019년까지 우리나라 10개의 서비스산업을 중심으로 자료포락분석 (DEA)을 이용하여 생산효율성을 측정하고 단절토빗회귀모형과 중도절단토빗회귀모형을 이용하여 그 결정요인을 분석하는 것이다. 분석결과, 첫째, 추정된 서비스산업의 효율성은 대체적으로 매우 낮았고 양극화되어 있었으며, '하수·폐기물 처리, 원료재생업'의 경우 기술적 비효율성이 규모의 비효율성에 기인하는 것을 알 수 있었다. 둘째, 결정요인 분석에서는 투자와 연구개발비는 기술효율성에 정(+)의 관계에 있고, 해외직접투자와 접대비는 부(-)의 영향을 주는 것으로 측정되었다. 또한, 규모가 큰 산업일수록 효율성도 높은 것으로 나타났다. 따라서, 우리나라 미래의 산업인 서비스산업의 발전을 위한 정부의 경제정책은 투자와 연구개발활동을 통한 거시정책과 해외직접투자와 인적자본의 융합 등 미시적인 부문이 동시에 고려되는 보다 융합적 정책이 필요하다.

Purpose - Major countries in the world continue to grow up without employment by the economy opening, more investment in foreign countries and technical innovation. Nevertheless, SMEs have job creation continuously. As this result, support for SMEs that is the source of job creation has increased attention. However, previous research between SMEs and job-creating is limited to the job creation effect of comparing with large companies, and R&D investment effect including government support. Also, many research provides the different result of correlation with technology innovation and job creation. Therefore, previous research has insufficient to explain job creation by which in the technology commercialization stage and the job-specific workforce. Research design, data, and Methodology - This study investigated the impact of customized R&D support upon job creation by using questionnaires of SMEs R&D service of K-Institution from 2009 to 2013. In detail, we analyzed the relationship between the technology commercialization stage and the usefulness of customized R&D support. Also, we added the analyzed the relationship between the usefulness of customized R&D support and the job-specific workforce. Results - Research result, Job creation had a significant relation to the usefulness of customized R&D support in product design stage and mass production stage. Also, R&D worker and production worker correlated with the usefulness of customized R&D support. These results indicate the importance of hiring R&D workers and production workers at the higher technology readiness. Conclusions -Therefore, this study suggests some implications for the government's SMEs support policy and the solve employment problems such as youth unemployment.

Farm mechanization has been rapidly progressed in rice farming since the 1980's, in Korea. The mechanization has been achieved up to 95-97% in the year of 1995, except irrigation and drying process. However, rice production cost remains much more expensive than the cost of other rice farming countries. Since labor cost shares a major portion of the production costs, it is essential to save labor cost with automation and more sophisticated mechanization. However, it requires great capital investment which causes farm management worse. Therefore, the computer program was developed which can select machines to minimize the management and maintenance cost by analyzing available working days in different areas, machinery to purchase, farming size, total farming size in a village, number of machines and custom fee.

The dies & molds are a very economical production tool and a high value-added product because of its mass production capability compared to other production methods. Due to the very stiff international competitiveness, the industries meet many obstacles. At this moment, measured the status, the international trends and try to find the vision and strategy to promotion of the industry. In Korea, large portion of dies and molds are still low value-added and make large number of tools. In order to advance this industry to the high-tech area and gain competitiveness in the golbal marketplaces, effective means of resource investment and strategy should be properly provided.

Operation simulation is a key factor to evaluate investment and operation in a power utility. Probabilistic production simulation is of major concern. With pumped-storage plant, production simulation is not an easy task, because its economy should fully be exploited. In addition, usual operation interval is a week rather than a day. Most existing models are based on approximate production simulation such as adopting simple priority orders of generations. This study is based on the more elaborate model developed by authors. Further, a policy of weekly coordination is established based on the Maximum Principle. Chronological load curve instead of usual load duration curve is used and the accuracy in simulation is enhahced. Resulting economics are compared. Deviation between these two toad curve is shown.

Production Improvement Method in TOC consists of five steps, but it is very difficult for most firms to implement it because it lacks the detailed methods at each step. This paper suggests some of detailed methods to implement the TOC. In the first step, computer simulation is used to identify the constraints in production lines. Subsequently, ASP, AUT, and CM calculation are defined for the second step, which are helpful to exploit the company's constraints. We also suggest the OEE method to effectively exploit the constraints of production lines in the factory. Finally the TOC/OEE procedure is suggested to optimize the investment in the fourth step. As an illustrative example, we introduce a case of a wafer manufacturer to adopt the suggested methods. The benefits of implementating the suggested methods are addressed in the framework of the balanced scorecard.
