  • At present, one of the big characteristics in electric power market in korea is unique seller but in the near future competitions are expected in the market. so additional service for the electric power are expected. Also with development of IT technology, remote inspection for power usage are possible so as consumption pattern analysis. KORAIL is one of the biggest consumer in electric power market so it is necessary to investigate power consumption pattern. This paper presents electric power rate definition program based on billing system database and also basic power rate optimization method. Base on the substation annual power usage DB data, the characteristic of the substation power consumption are investigated and effective electrical billing system are compared each other. Through this program it is verified that we can save more then several hundred million won for a year.

  • RPS(Renewable Portfolio Standards)란 전력의 일정 양 또는 비율을 신$\cdot$재생에너지에 의하여 충당하도록 의무화하는 제도로써 정부지원에 의존한 신$\cdot$재생에너지 보급을 시장기능에 의하여 활성화하려는 새로운 정책도구이다. 본 논문은 이와 같은 RPS제도의 국내 도입에 대비하여 RPS의 기본 개념과 시장기구 하의 운용방식, 정책설계 시 고려사항 등을 살펴보았다. 이를 통하여 신$\cdot$재생에너지 전망 및 계획상의 문제점과 RPS도입에 따른 전력시장에서의 효과 등을 확인하고, 최종적으로는 향후 RPS도입을 위한 정책제언을 도출한다.

  • 부동산분야에서 전통적인 예측방법과 비교하여 보다 예측력을 높일 수 있는 방법을 찾으려 한다. 이에 앞서 신경망 모형의 적용가능성을 살펴보고, 기존의 연구를 토대로 한 신경망 이론의 정의, 구조, 장단점 등을 살펴본다. 구체적인 적용가능성을 확인하기 위하여 동일 데이터로 회귀분석과 신경망분석을 통한 모형을 구축하고, 예측정확도 측면에서 신경망모형의 적용 가능성을 검토한다. 부동산학에서 기존에 회귀분석에 치우쳐 있던 연구방법을 신경망분석까지 확장하고, 특히 예측정확도 측면에서 우수성이 검증되고 있는 신경망모형에 대한 연구를 활성화 하고자 하는데 본 연구의 목적이 있다. 연구방법으로는 분양가격에 영향을 주는 거시경제변수를 모형화 한다. 그 모형설정 후 회귀분석과 신경망분석으로 결과를 비교하여 보다 예측 정확도가 높은 것을 찾는다. 그 결과 신경망모형의 예측정확도가 상당히 높게 나타났다.

  • 본 논문은 유료방송서비스를 대상으로 경쟁법의 시장 획정 원리를 이용하여 상품별 관련시장을 실증적으로 획정하고, 시장 획정과정에서 확인된 상품 간 경쟁관계를 토대로 하여 현행 제도의 타당성을 분석하고 개선방안을 제시하였다. 임계매출손실률 검정법을 적용하여 각각의 유료방송서비스별로 관련시장을 획정한 결과, 현재 시장에서는 모든 유료방송서비스 또는 적어도 아날로그케이블방송, 디지털케이블방송, IPTV 간에 경쟁법적으로 유의미한 경쟁관계가 형성되어 있음을 확인하였다. 이러한 분석 결과는 현재 종합유선방송(위성방송)과 IPTV에 상이하게 적용되는 규제들이 규제차별임을 의미한다. 특히 IPTV만을 독립된 시장으로 획정하는 것으로 해석되는 인터넷멀티미디어방송사업법 제20조는 플랫폼사업자 간 경쟁 활성화와 공정경쟁을 훼손할 여지가 크므로, 콘텐츠 동등접근의 대상 플랫폼사업자를 종합유선방송(위성방송), IPTV로 확대할 필요가 있다. 또한 콘텐츠 동등접근의 의무가 부과되는 주요 방송프로그램의 지정과 관련하여 지상파계열 PP와 독립 PP가 제공하는 인기 유료방송채널은 플랫폼사업자 간 경쟁 활성화 차원에서 주요 방송프로그램에 포함되어야 함을 주장하였다. 마지막으로 플랫폼사업자에 대한 시장점유율 규제는 경쟁관계가 형성되어 있는 사업자들의 전체 가입자 수를 기준으로 동일한 상한을 설정하는 것이 타당함을 보였다.

  • Dynamic changes in the field of labor relations have become a general trend in the world practice. These changes are due the impact of globalization and technological innovation above all. Concept of "precarization of employment" appeared due the new emerging labor relations. This term has been used for more than thirty-five years, but there is still no generally accepted definition of it. A wide range of authors' viewpoints on problem of precarization makes it vague and impossible to strictly to identify its borders. Features of its manifestations in different countries also complicate the problem. Kazakhstan is a country with export-oriented economy of raw materials. At the same time government try to solve the problem for the industrial-innovative development of the economy. These two factors bring additional specific features in the manifestation of the precarization of employment in the country. The aim of the paper is to identify the features of "precarization of employment" concept in Kazakhstan's practice, based on the proposed definition.

  • Generic medication market has been increased for economic reasons in Korea. Health authorities worldwide recommend the use of generic medications nowadays. However, patients in Korea are not familiar with the generic medications and considerable percent of those do not know the definition of the generic medications. The purpose of this study was to evaluate adults' knowledge and perception on the generic medications at community pharmacies in Korea. This study was a 11-questionnaire survey conducted from August 9, 2010 to August 27, 2010. Of the 204 respondents, 63 (30.9%) responded that they knew what a generic medication was, but only 16 (25.4%) of those answered that generic medications had the same efficacy as brand medications. When pharmacists were the source of generic medication information, more patients reported having knowledge about the definition of generic medications correctly compared with other sources. Patients with negative experience with generic medications within 6 months were more reluctant to generic substitution suggested by a pharmacist than those with positive experience. Based on the results of this study, further studies should be conducted to establish the best way to provide generic medication information for patients.

  • This study focuses on the risk management of "Digital Goods" appeared with the progress of information technology(IT) in international transaction. As a result of that digital goods have a lot of uncertainty between the general goods or service which have been deal with object of international transaction broadly because digital goods hold uniqueness. In this study, the author give a definition of "Digital Goods" and make an examination of uniqueness of that in international transaction. Next, six risks are defined base on risk theory and risk analysis matrix applying risk mapping model is made. Conclusionally, risk transfer as insurance is adequate to manage business risk, security risk, credit risk and legal risk. Meanwhile, risk avoidance is adequate to manage reputation risk and market risk. But, this study have following three limits. Firstly, concerning definition of the risk, real case is not applied owing to lack of transaction data. Secondly, measuring of the risk is not based on absolute data but relative data. Lastly, suggesting way of risk management is not concrete and practical to international trader of digital goods.
