  • This paper compares efficiency results and performance targets for academic departments in a local private college using DEA (Data Envelopment Analysis). Because of an aging society, a smaller school-age population entering colleges, and enhanced accreditation standards by the government, colleges and universities are not recruiting and retaining sufficient students and therefore are struggling for survival. In contrast to popular four-year undergraduate universities concentrated in Seoul and its satellite cities, retaining students is critical for the survival of local private colleges in poor or remote regions. Therefore, it is very important to identify the factors involved in the retention of students in the various departments of a college. However, given the different characteristics of the departments, it is difficult to identify one unique or robust set of standards to evaluate their performance. The purpose of this paper is to maximize student retention capabilities by ensuring that additional resources are assigned to efficient DMUs, while, inefficient DMUs are given benchmarked targets. Based on previous studies and college accreditation standards, this paper presents indices to be used in evaluating the efficiency of academic departments in a college. In evaluating relative efficiency, this paper uses the output-oriented BCC model. To define target levels to be achieved for efficient DMU, a multi-stage DEA procedure is used.

  • 민간투자사업의 자본구조는 사업시행자가 출자한 자기자본과 대출금융기관으로부터 조달한 타인자본으로 구성된다. 민간투자사업 기본계획에서는 사업시행자의 최소 자기자본비율을 25%로 규정하고 있으며, 일반적으로 정부와 사업시행자 간의 실시협약을 통하여 자본구조를 결정하게 된다. 그러나 민간투자사업의 자본구조는 사업의 수익률과 재무적 안정성을 결정하는 중요한 기준이기 때문에 자금조달계획 수립 시 자본구조에 따른 수익률의 변동성을 파악하고 적정 수익률과 재무적 안정성을 고려하여 자본구조를 최적화할 필요가 있다. 본 연구는 민간투자사업의 수익률과 재무적 안정성을 동시에 극대화할 수 있도록 자본구조를 최적화하기 위한 방법론을 제시하는데 그 목적이 있다. 이를 위하여 기존 민간투자사업들의 자본구조를 고찰하고 민간투자사업 재무모델을 분석하였다. 재무분석을 바탕으로 최적 자본구조를 결정하기 위해 효용함수 개념과 다목적 유전자 알고리즘을 이용한 자본구조 최적화모델을 제시하였다. 제시된 최적화 모델을 인천공항철도 민간투자사업에 적용하여 최적 자본구조를 도출하였고 민감도 분석과 시나리오 분석을 통해 그 활용성을 검증하였다. 사례분석 결과, 최적 자기자본비율은 실시협약에서 결정된 30%보다 낮은 22.3%에서 결정되었으며 이는 자기자본비율을 더 낮추어도 수익률과 재무적 안정성을 유지할 수 있다는 것을 시사한다. 본 연구는 수익률과 재무적 안정성을 동시에 고려하여 최적 자본구조를 결정함으로써 민간투자사업의 사업시행자에 적합한 자본구성과 자금조달을 위한 합리적인 의사판단 기준을 제시하였으며 사업시행자의 수익률 향상에 기여할 것으로 기대된다.

  • Since MegaStudy started e-learning business for Korean high school students, the Korean e-learning industry began to expand and steadily gain attention. This paper focused on the analysis of the development of the Korean e-learning business for teens and the growth of MegaStudy. The three institutional mechanisms were used to examine the factors that aided the development of the business. The regulatory mechanism was the government policy to prevent the expansion of the offline private education sector, which greatly aided the growth of the e-learning business. The mimetic mechanism was the notion to mimic the characteristics of the Korean e-business initiatives. The normative mechanism involved the widespread social norm suggesting that every student should be given an equal opportunity of private education. This paper also examined the case of MegaStudy as a successful case of the e-learning companies. It analyzed the business model of MegaStudy, which is based on its advantage as the front-runner and its high-quality contents and services.

  • Construct ion sector government policies are targeted towards regulation than facilitation and management. This approach often fails to integrate different segments of the public and private and seems to be inadequate in encouraging the private sector to achieve better quality construction. This situation suggests a need for a better and systematic approach for construct ion policy making. This paper suggests a model-based approach to public policy making using system dynamics approach. Singapore government's policy making efforts to encourage the use of prefabrication are discussed as an application example. This paper presents system models which discuss strengths and weaknesses of the current construction system in Singapore using casual loops, and highlights the feedback processes that would be useful in decision making for the government. Based on these system dynamics models, this paper identifies four major potential policy interventions policy interventions.

  • A Systematic Wealth Management Framework (SWMF) was developed as a private banking management tool to enable more integrative personal finance management of personal wealth. It is a reference model that provides an unified framework for development, operation, and management and makes provision for personal financial services in today's complex financial environment. This study suggested some practical results from banks and insurance companies that have established SWMF as the differentiation business strategy for wealthy customers. The focus of this manuscript is on capturing the methodological approach most financial institutions in Korea adopted to execute new e-finance planning and implementation based on the SWMF. The alignment between the wealth management business goals and information system architecture at an organization constitutes the main theoretical basis of the study. Relevant discussions are made on the wealth management framework as a general business model for financial industry, on the functional relationship between new information systems and business organizations. Finally, lessons learned from the SWMF implementation are discussed.

  • This paper focuses on construction cost volatility for the purpose of private sector investment by use of a financial model with key indices of IRR and DSCR (Debt Service Coverage Ratio). A case project, 1,000 MW pumped storage hydropower plant, has shown that its financial impacts by cost volatility of underground works are less measured than interest rates impacts by interest rate of loans. Probabilistic analysis of costs under geotechnical conditions has been made by Indicator Kriging method. And, in the modeling of interest rates, geometric Brownian motion has been applied. Both of these impacts are measured on the same financial model.

  • As a nation experiencing rapid economic growth, South Korea and its government have made a continuous effort toward efficient research investments to achieve transformation of the Korean industry for the fourth industrial revolution. To achieve the maximum effectiveness of the research investments, it is necessary to evaluate its funding's worth and default risk. Thus, incorporating the concepts of the Black-Scholes-Merton model and the Greeks, this study develops a default-risk evaluation model in the foundation of a system dynamics methodology. By utilizing the proposed model, this study estimates the monetary worth and the default risks of research funding in the public and private sectors of Information and Communication technologies, along with the sensitivity of the R&D economic worth of research funding to changes in a given parameter. This study finds that the public sector has more potential than the private sector in terms of monetary worth and that the default risks of three types of research funding are relatively high. Through a sensitivity analysis, the results indicate that uncertainty in volatility, operation period, and a risk-free interest rate has trivial impacts on the monetary worth of research funding, while volatility has large impacts on the default risk among the uncertain factors.

  • This study aims to enhance the accuracy of effective demand analysis for publicly supported private rental housing by integrating the RIR into the traditional Mankiw-Weil (MW) model. Traditional models like the M-W model, which account for household income, housing costs, and household size, often fall short in estimating demand driven by large-scale development projects. By integrating the RIR factor, this study introduces a more accurate and practical approach to analyzing effective housing demand. Findings show that the modified M-W model incorporating RIR predicts effective demand with greater precision than traditional methods. This advancement allows developers to plan projects more efficiently and aids governments and local authorities in implementing more effective housing policies. Furthermore, the study assesses the real housing cost burden on households, elucidating their capacity to pay housing costs based on household size and income quintile. This information enables policymakers to design targeted housing support policies for specific demographic groups. Additionally, the research provides comprehensive policy recommendations tailored to various regions and housing types. Overall, this study lays a vital groundwork for the long-term analysis of the effects of economic changes and housing market trends on effective demand.

  • 우리나라의 민간경비는 경제발전과 더불어 비약적으로 성장하고 있다. 그러나 최근 사회적 이슈로 대두된 용역경비업체의 폭력사건에서 보는 바와 같이 민간경비에 대한 국가적 규제 및 자격검증 제도에 대한 국민적 요구가 증대되고 있다. 민간경비에 대한 국가적 관리의 부재는 영세업체의 난립과 자격 없는 경비원의 고용으로 인해 국민의 신뢰를 떨어뜨리게 된다. 본 논문은 민간경비규제 관련 미국연방법과 캘리포니아 주 법제도를 상세히 살펴보고 이를 통하여 정책적 시사점을 도출하는데 그 목적이 있다. 구체적으로 미국 연방규제법인 민간경비원고용인가법(PSOEAA)의 내용과 캘리포니아 주의 민간경비 자격 및 교육훈련제도를 살펴본다. PSOEAA에 따르면, 공개대상 전과도 중죄뿐만 아니라 부정직성 허위의 진술과 같은 윤리적 요소가 포함된 범죄까지 포함하고 있고, 확정판결이 나지 않은 계류중인 범죄에 대해서도 통보하도록 되어 있었다. 아울러 경비업자는 매 12개월마다 해당 경비원의 전과사실을 조회할 수 있기 때문에 고용 후 발생하는 민간경비원의 범죄에 대해서도 적절한 관리 및 확인이 가능하였다. 캘리포니아 주의 경우 우리와 다르게, 주 소비자 서비스청 산하의 소비자업무국(the Department of Consumer Affairs)에서 민간경비업무를 담당하며, 면허의 발급 및 취소 경비원의 교육 기준 등에 관한 세부적인 지침 및 실무사항은 소비자업무국 내의 '경비 및 조사서비스'과(the Bureau of Security and Investigative Services)에서 처리되고 있었다. 나아가, 캘리포니아 주의 민간경비규제법령(Business and Professions Code)은 경비서비스를 (1) 전속민간경비업, (2) 민간경비서비스(계약경비업), (3) 경보서비스로 분류하여, 경비서비스별로 면허 자격 교육훈련 등의 요건을 차별화 세분화 단계화하고 있었다. 민간경비는 국민의 안전과 직결되는 분야로서 공공재의 성격이 강하며, 이에 전문성 신뢰성 등을 확보하기 위해서는 정부 주도의 적극적이고 전문적인 관리가 필요하다. 따라서 본 논문에서는 미국의 사례를 바탕으로, (1) 부적격자 배제를 위한 전과요건의 실질적 강화, (2) 민간경비 전문담당 부서의 설치, (3) 법적인 경비업무 성격에 따른 선택과목의 다변화 및 시간에 따른 단계별 교육진행이라는 정책적 시사점을 최종적으로 제시하였다.
