The number of items and the market size of the senior-friendly medical devices are rapidly increasing, and it is necessary to come up with a safety management plan for senior-friendly medical devices. We searched and analyzed the definition and policy of senior-friendly medical device, and classified medical device items of the Ministry of Food and Drug Safety, calculated market sizes and manufacturing export import results by classification, and investigated the current state of senior-friendly industry and the fields of its culture. In order to prepare a safety management plan, we reduce the number of items that need to be managed intensively by extracting 69 items for administration, that are substantially harmful to the elderly. As specific safety management plans of items for administration, we propose plans for introductions of readability-enhanced labeling, QR codes for cautions and manuals, universal design mandatory, UDI code system with considering a balanced viewpoint of the industry development.

Flexibility has become a key objectives in the design of manufacturing systems and a critical measure of total manufacturing performance. The need for flexibility is increasing due to some environmental change such as changing technical characteristics of the products and the changing nature of market demands. Most importantly, flexibility embodies competitive value for a manufacturer. Although the importance of flexibility has stressed in the various research, very few attempts have been made to synthesize the literature dealing with definitions and measure of flexibility. It is this issue that have motivated us to search for the definition and classification of flexibility.

The virtual power plant (VPP) is a new technology to achieve flexibility as well as controllability, like traditional centralized power plants, by integrating and operating different types of distributed energy resources (DER) with the information communication technology (ICT). Though small-sized DERs may not be controlled in a centralized manner, these are more likely to be utilized as power plants for centralized dispatch and participate in the energy trade given that these are integrated into a unified generation profile and certain technical properties such as dispatch schedules, ramp rates, voltage control, and reserves are explicitly implemented. Unfortunately, the VPP has been in a conceptual stage thus far and its common definition has not yet been established. Such a lack of obvious guidelines for VPP may lead to a further challenge of coming up with the business model and reinforcing the investment and technical support for VPP. In this context, this paper would aim to identify the definition of VPP as a critical factor in smart grid and, at the same time, discuss the details required for VPP to actively take part in the electricity market under the smart grid paradigm.

최근 국내 BIPV 시장은 "제로에너지 건축물 인증 의무화 제도(2020~)" 도입으로 시장 활성화가 기대되고 있지만, 현행 국내 BIPV 시공 기준 내 정의 내용의 경직성 등으로 인해 다소 답보 상태에 있다. 또한, 국내 BIPV 정의와 표준화 개정이 지체되어 벽에 구조물을 설치하고 모듈을 대충 고정한 것만으로 BIPV라고 인정된 사례가 있을 만큼 제도가 허술한 상태이다. 이로 인해 발생한 피해는 소비자에게 돌아갈 수 있으며 BIPV에 대한 부정적인 인식만 심어주고, 시장 전체를 정체시키는 결과를 불러올 수도 있다. 이에 BIPV 정의 중, 시장 부진 원인, 불합리한 규정 등에 대해 문헌조사, 선행 연구조사(인용) 및 현장사례 조사 등 개정 필요항목들을 사전 검토 및 설문 항목 검토 후, BIPV 분야 산업계 및 연구계 등 전문가를 대상으로 델파이 설문 조사를 거쳐 개정 대안을 분석 마련하고, 전문가 검토 의견 등을 종합 반영 및 보완하여 IEC 국제표준 정의 일부 인용.절충안 등 국내 BIPV 정의 개정방안을 도출하였다.

The number of contracts for bundling services in a domestic telecommunication market records 1.3 miilion as of the first half year in 2007, and steadily increased to 8.97 million in 2010, to 12.76 million in 2013. In 2014, 70.4% of telecommunication service consumers are found to subscribe to bundling service. Bundling services provide consumers with benefits such as price discount, convenience, increase ARPU. However, a market dominant player in a specific market may transfer its market power to another market by selling bundling services. SSNIP has been adopted to provide a market definition. However, SSNIP is not suitable to measure the effect of market power transition through bundling services because SSNIP cannot measure the effect of changeover sales of bundling services. Thus, in this study, we have investigated the effect of market power transition through bundling services reflecting market power effect and quality upgrade using Gross Upward Market Power Pressure Index metho and reviewed UPP and derivative UPP models.

How health care providers compete and how competition among them affects their behavior are crucial questions in theory and health policy. In ordinary markets, competition improves social welfare, However in health care markets facing uncertainty and information asymmetry, competition can take the form of wasteful quality competition and result in cost increase. The purpose of this study is to examine the characteristics of hospital service markets and examine the impact of hospital competition on hospital behavior, more specifically hospital cost and the size of personnel. Based on patient discharge data of 2002 by the Ministry of Health and Welfare and Korea Institute for Health and Social Affairs, and health insurance EDI claims data of 2002, this study measures the degree of competition in the inpatient service market of hospitals, using variable radius method and Herfindahl index. The result of the study shows that the hospital service market consists of on average 3.13 government administrative units(shi, gun, or gu). Compared with hospitals, general or general specialized hospitals cover larger markets and operate in more competitive markets. Nearly 60% of patients use hospitals, which are not located in their government administrative units, meaning that market definition based on variable radius is better than the conventional method of market definition based on government administrative units. The results of multivariate analysis show that competition is not associated with high cost index of hospitals. But hospitals in more competitive markets employ larger(more intensive) input of personnel per 100 beds, implying that hospital competition in Korea can have the form of quality and cost-increasing competition.

Technology measurement is related with how to construct indicators of technological change and relative ranking of technological sophistication. Many attempts have been made to understand the measurement of technology. However, technology measurement still remains little understood problem in spite of its importance. This article is concerned with improving the measurement of technology by introducing market factors into the model. It illustrate a simple approach to the measurement of technology. This approach is based on the characteristic-space paradigm of technology. A relative ranking of technological sophistication for a product is measurable as a set of characteristics. The main feature of the proposed approach is the combination of technical factors and market factors. Technical factors are reflected in the definition of technological sophistication. Market factors are embraced in the determination of the relative importance assigned to each technology defining characteristics. Thus, the weight is determined by technical factors and market factors, which differentiates the study from the past based on judgmental technique such as experts' opinion.

This paper presents a method for improvement of capacity payment in CBP(cost based pool) market. Capacity payments have been used as common mechanisms in various pools for compensating generators recognized to serve a for reliability purpose. Ideal pricing for capacity reserves by definition achieves a balance between economic efficiency and investment incentives. That is, prices must be kept close to costs, but not so low as to discourage investment. However, the price set is not easy. This paper concludes with market design recommendations that apply fuzzy theory for improvement of capacity payment. Following this model, market participants decided on their own based on their forecast to the market demand and the payment for it.
