본 연구는 이동통신 정책변화에 따른 사업자간 경쟁양상을 분석하였다. 이동통신 시장은 시장진입이 제한적으로 한정된 사업자들이 독점 형태로 경쟁하게 된다. 이 과정에서 정부는 소비자의 권리보호 및 기업들 간의 유효경쟁체제를 위해 기업의 경제활동을 규제하는 역할을 해왔다. 그동안 이동통신시장에서의 정부규제에 대한 성과나 결과를 분석하는 많은 연구들이 있었지만 제도의 중첩으로 인한 복합적 양상을 분석하는 연구는 부족하였다. 이에 본 연구는 실제 데이터를 사용하여 제도의 중첩으로 인한 사업자 경쟁구도의 복합적 양상을 확인한 첫 연구라는 점에서 그 의의를 갖는다. 본 연구는 기업의 성과지표인 가입자 수, 번호이동자수, 매출액 등의 실증데이터를 사용하여 정책변화에 따른 통신사업자간 경쟁양상을 연구하였다. 연구결과 통신시장에 도입된 정부 정책은 시장경쟁 촉진과 고착화된 경쟁구도 완화에는 긍정적인 영향을 미쳤지만 통신사 재무성과 개선 측면에선 부정적인 영향이 있었음을 확인하였다. 특히 단통법은 이동통신사간 유입영향력 차이를 줄이며 시장 안정화를 유도하고 MVNO의 점유율 상승에 발판을 마련하는 등의 긍정적인 효과도 있지만, 일정 기간 이후 기존 MNO 사업자의 영향력이 증가하여 MVNO의 경쟁력이 약화되는 부정적 변화를 확인하였다.

Purpose: This study was conducted in order to understand the influence of professionalism on job satisfaction and job performance of the physical therapist. Methods: Subjects were 148 physical therapists. We conducted a questionnaire survey on professionalism, job satisfaction, and job performance. Professionalism questions were 'Compliance of professional organization', 'Beliefs about public service', 'Autonomy', 'Beliefs about self-regulation', and 'Vocation awareness of the profession'. A regression analysis was then performed. Results: The subjects' average score for professionalism was $3.18{\pm}0.31$ points. The lowest score for satisfaction was observed for 'Compliance of professional organization'. Professionalism had an effect on job satisfaction. 'Vocation awareness of the profession (${\beta}=0.44$, p<0.001)', 'Beliefs about public service (${\beta}=0.25$, p<0.01)', and 'Autonomy (${\beta}=0.17$, p<0.05)' had an effect on job satisfaction. R square=0.46 (adjusted R square=0.45). Professionalism had an effect on job performance. 'Autonomy (${\beta}=0.29$), p<0.001)', 'Vocation awareness of the profession (${\beta}=0.22$, p<0.05)', and 'Beliefs about self-regulation (${\beta}=0.18$, p<0.05)' had an effect on job performance. R square=0.25 (adjusted R square=0.22). Conclusion: The results of this study indicate that in order to improve job satisfaction and job performance, it is necessary to improve professionalism. Therefore physical therapists should improve their professionalism ('Compliance of professional organization', 'Beliefs about public service', 'Autonomy', 'Beliefs about self-regulation', and 'Vocation awareness of the profession') in order to improve their job satisfaction and job performance. In addition, research to improve professionalism of the physical therapist should be continued.

본 연구는 방송 통신 서비스의 경품 및 요금 감면 행위의 위법성 판단 기준과 규제 기관의 위법 행위 적발 및 시정조치 등을 분석함으로써 규제의 실효성 여부를 알아보고 효과적 규제 방안을 제안하고자 하는 연구목적을 지니고 있다. 연구 결과, 최근 들어 이용자에게 제공되는 경품과 요금 감면액의 차이가 급속히 증가하고 있음을 알 수 있었다. 또한 공정거래위원회는 부당성 판단 기준을 비용 이하로 요금을 책정하는 경우에만 부당염매로 판단하고 있지만 방송통신위원회는 '가입자 1인당 평균 예상이익'으로 적용하고 있는데, 모든 사업자의 평균값을 기준으로 함으로써 기업이 제공하는 서비스품질의 차이나 선발기업과 후발기업 간 비용 구조 차이를 고려하지 않아 후발 기업의 마케팅 비용을 상대적으로 높게 허용해주는 결과를 낳고 있다. 이용자 차별금지를 통해 후발 기업의 가입자 증가와 영업이익의 증가를 지원하는 결과를 가져오지만, 이는 직접적인 규제 목적이 아니며 적극적으로 정보를 추구하는 정보이용자의 후생이 감소하는 결과가 나타나고 있어 부당성 판단 기준에 대한 재고찰이 필요함을 제안하였다.

Recently, many countries have placed great attention on energy security and climate changes. Governments are promoting the construction of renewable energy projects with regulatory support in Korea. Despite an increasing penetration of renewable resources, however, the photovoltaic and wind power are underutilized due to the endemic problems such as difficulties of output control and intermittent output. The Energy Storage System (ESS) is proposed as a good solution for solving the problems and has been studied in both the private business and the government. However, because of inefficient aspects, the research has been carried out for improving high costs and a small capacity. In addition, the ESS is currently installed for using only one purpose which is frequency regulation or transmission congestion relief such that has an economic limitation. Therefore, methods which are becoming economically justifiable to increase the penetration of the ESS is required. Thus, this paper presents in terms of operation efficiency to improve economic feasibility of the ESS currently used. mainly, there are two aspects for the operation efficiency. Firstly, it is intended to improve the utilization rate through a process that can utilize the ESS for various purposes. It is necessary to be able to use for other purposes by classifying and clustering for increasing the efficiency of availability. The clustering method is proposed to conduct the grouping the ESS. Especially, it is proposed to utilize ESS for frequency regulation service which is the one of ancillary services in the power system. Through case studies, it is confirmed to secure the necessary resources by clustering small size ESS.

Along with the urbanization, the risk of urban flooding due to climate change is increasing. Flood regulation, one of the ecosystem services, is implemented in the different level of function of flood risk mitigation by the type of ecosystem such as forests, arable land, wetlands etc. Land use changes due to development pressures have become an important factor in increasing the vulnerability by flash flood. This study has conducted evaluating the urban flood regulation service using InVEST UFRM(Urban Flood Risk Model). As a result of the simulation, the potential water retention by ecosystem type in the event of a flash flood according to RCP 4.5(10 year frequency) scenario was 1,569,611 tons in urbanized/dried areas, 907,706 tons in agricultural areas, 1,496,105 tons in forested areas, 831,705 tons in grasslands, 1,021,742 tons in wetlands, and 206,709 tons in bare areas, the water bodies was estimated to be 38,087 tons. In the case of more severe 100-year rainfall, 1,808,376 tons in urbanized/dried areas, 1,172,505 tons in agricultural areas, 2,076,019 tons in forests, 1,021,742 tons in grasslands, 47,603 tons in wetlands, 238,363 tons in bare lands, and 52,985 tons in water bodies. The potential economic damage from flood runoff(100 years frequency) is 122,512,524 thousand won in residential areas, 512,382,410 thousand won in commercial areas, 50,414,646 thousand won in industrial areas, 2,927,508 thousand won in Infrastructure(road), 8,907 thousand won in agriculture, Total of assuming a runoff of 50 mm(100 year frequency) was estimated at 688,245,997 thousand won. In a conclusion. these results provided an overview of ecosystem functions and services in terms of flood control, and indirectly demonstrated the possibility of using the model as a tool for policy decision-making. Nevertheless, in future research, related issues such as application of models according to various spatial scales, verification of difference in result values due to differences in spatial resolution, improvement of CN(Curved Number) suitable for the research site conditions based on actual data, and development of flood damage factors suitable for domestic condition for the calculation of economic loss.

As needs for telecommunications services diversify, an increasingly wide range of telecommunications services is becoming available in the market. Any subscriber can find a service to satisfy his/her telecommunication requirements and competition between providers to retain heavy users is increasing. Service price reductions are one retention strategy, although price reductions for one service can affect the individual-level usage for other services. Price reductions can also be imposed on a service provider by regulation. For these reasons, understanding how price reductions affect service usage is of growing importance to the telecommunications industry for purposes of pricing and tariff development. In this paper, we develop an individual-level usage model for telecommunications services and analyze the effects on usage of a price reduction. We apply the model to age-stratified aggregate traffic data for a Korean mobile telecommunication service provider. Finally, we develop a model to support a market segmentation and price reduction strategy.

Concerning the regulation of Internet service and the control of electronic commerce in China, It has not specific regulation and various rules or measures to enforce it yet. The common regulatory measures are that online business in some special areas must acquire a license or approval from relative agencies in advance. But whether licensing is an effect regulatory measure still takes time to verify. Accordingly these measures must be unified or coordinated to be enforced effectively. In order to encourage the development of E-Commerce, China will need to focus on developing rules that take advantage of the internet to encourage the economy, and establishing new legal rules or amending the traditional law to create a safe and secure legal environment for online transactions.
