새로운 통신서비스 사업자들이 계속적으로 등장하는 실정에서 기존 사업자와 접속이 불가피해진다. 이때, 발생할 가장 중요한 문제중 하나는 접속료 정산문제일 것 것이다. 본 고에서는 현재 제외국에서 접속료 정산방법으로 연구중인 통신망 비용모델들의 특징과 적용 범위 등을 살펴보고 국내 도입의 가능성을 서술하였다.

It is important to estimate the future maintenance budget of all SOC infrastructure at the national strategic level. In this study, Based on a currently available statistics data, we predicted future maintenance investment for all SOC infrastructure in Korea. We have studied the applicable prediction models, and we developed the prediction models that can calculated the future maintenance cost by a real expenditure date. The subjects of facilities are bridges, tunnels, pavements, harbors, dams, airports, water supply, rivers and port. As a result of total estimated cost, eight types of SOC infrastructures are about 23 trillion won for the next 10years, and the most expensive facilities are road pavements and bridges.

고정금리 상품의 투자에서 이자율 변동 위험을 피할 수 있는 방법으로 많이 쓰이는 것은 듀레이션을 이용한 면역 모델(Bond Portfolio Immunization Model)로, 이것은 이자율 변동에 대해 포트폴리오의 가격 민감도인 듀레이션을 이용하여 자산과 부채의 변화를 일치시키는 방법이다. 그러나 이 전략은 수익률 곡선이 평형하게 이동한다는 가정(Parallel Shift Term-Structure)을 단점으로 가지고 있어 현실에 적용될 경우 오차가 발생하게 된다. 본 연구에서는 선험적(empirical) 방법으로 평형하지 않은 움직임을 가진 기간구조의 함수(Term-Structure Function)를 정의하고 면역 모델을 부채의 현금흐름에 대해 개별적으로 적용하는 새로운 면역 전략 모델을 구성하고 실험한다

기입뿐만 아니라 정부차원에서도 시스템을 통합하여 효율적으로 관리하는 방법에 대한 관심이 증가되고 있다. 본 논문에서는 웹서비스와 같은 웹 기술에 기반하여 정보자원을 통합하고 활용하는 방법을 제안하고자 한다. 제안하는 통합 모델은 기존 시스템의 재구성에 대한 부담을 줄이면서 시스템을 통합하는 레지스트리를 이용한 Loosely-coupling 방식을 지향하고 있다. 제안하는 통합 모델은 전체 시스템의 효율성을 높이면서도, 투자비용에 대한 부담을 줄일 수 있는 차기 전자정부의 모델이 릴 수 있을 것으로 기대된다.

지식ㆍ정보화시대에 지식 기반형 산업의 대표 주자로 디자인 산업이 부각되고 있다. 디자인 산업은 제품의 기술개발에 비해 적은 투자비용으로 차별화, 고급화, 고부가가치화 될 수 있으므로 범 국가적 차원에서나 기업차원에서도 디자인 개발에 많은 투자를 하고 있고 디자인 분야에 마케팅 및 신경영기법 도입을 강화하고 있다. 기업이 추진하는 디자인 개발의 가치는 그 경제적 타당성을 계량적이고 과학적으로 분석할 때에만 그 제품의 경쟁력이 향상되는 것이다. (중략)

웹캐스팅 구축에 있어서 가장 먼저 선행되어야할 과제는 사업계획의 확정에 있다. 실제로 구축에 임하는 상당수의 경우에는 체계적인 사업계획이 미비한 경우가 상당히 많은데, 사업계획을 통해 전체 구축에 소요되는 일관된 정책과 전략을 수립하기 때문에 반드시 사업계획 수립에 대한 투자를 바란다. 사업계획을 통해 사업전략, 마케팅 계획, 수익모델, 투자계획과 조직구성안 등이 체계적으로 정리되어진 후에 구축작업에 임하는 것이 시행착오와 손실비용(시간 포함)을 줄일 수 있는 최선의 방법이다.

Impact investment involves investing in companies that pursue both social value and financial returns. It focuses on addressing various social problems through innovative solutions while generating profits. The domestic impact investment ecosystem has experienced significant growth with the support of the government and public institutions. In 2021, it witnessed a 3.5-fold increase over three years, reaching a total of 700 billion won in operating assets. In order to foster qualitative growth alongside this quantitative expansion, it is crucial to conduct research specifically on impact investment, which sets it apart from conventional venture investment. This study aims to empirically analyze the unique factors that influence impact investment decisions. Firstly, the factors affecting investment decisions were identified through a literature analysis. Then, a consultation and Delphi survey involving 11 representatives and evaluators from impact investment companies was conducted to determine the major investment determinants. Subsequently, an AHP (Analytic Hierarchy Process) survey was carried out with 10 impact investment evaluators to ascertain the relative importance of these factors. The analysis revealed the following order of importance for the top factors: market>entrepreneur(team)>product/service>finance. Furthermore, the importance of specific factors was identified in the following order: market competition and entry barriers>new market creation>market growth and potential expansion>team expertise and capabilities. Unlike previous studies that primarily focus on general startup investment factors, this research demonstrates that impact investment places greater emphasis on market-related factors and considers the sustainability and profitability of the business model to be more important than the social impact of social ventures.

The government introduced private infrastructure projects in order to reduce its financial burden by introducing private sectors efficiency and creativity and by utilizing their funds. Through revision, the act on the private investment of the infrastructure, many changes were made in the private investment system. The evaluation task to assess the project proposer's capability and to select a promoter is regarded as the most important process for fairness and transparency of the project. In this study, the improvement of project plan evaluation task of current private infrastructure projects is proposed based on the standard guideline for evaluation procedure of private infrastructure projects provided by Korea Development Institute. In addition, software program for evaluation procedure is made to improve the efficiency and enableconvenient evaluation task.

This paper attempts to offer an effective strategy of hedge fund based on trade probability control in the futures market. By using various technical indicators, we create an association rule and transforms it into a trading rule to be used as an investment strategy. Association rules are made by the combination of various technical indicators and the range of individual indicator value. Adjustments of trade probabilities are performed by depending on the rule combinations and it can be utilized to establish an effective investment strategy onto the risk management. In order to demonstrate the superiority of the investment strategy proposed, we analyzed a profitability using the futures index based on KOSPI200. Experiments results show that our proposed strategy could effectively manage and response the dynamics investment risks.

Although a well-established line of research has addressed the funding decision, the activities of investee startups to receive funding have been overlooked because prior research has been conduced from investor's point of view. In addition, funding does not result from one off decisions but from decision process with many stages. Moreover, the emphasis placed on specific investment criteria varies by different stages during the process. Therefore, understanding the initial funding of startups requires to analyze the strategic behaviors of startups throughout the entire funding decision process from first meeting with investors to funding success. This study investigates the initial funding process of startups, and the analysis is based on a case study of LetinAR one of the successful startups founded by students in South Korea. This study investigates how early start-ups were able to receive funding from startup's point of view, and the analysis is based on a case study of LetinAR, an augmented reality(AR) startup using Pin mirror technology. By adding "legitimacy building" stage that had not been addressed previously, we divided funding process into four stages: 1) legitimacy building, 2) familiarization, 3) screening, and 4) bargaining phase. We did not only analyze major criteria, but also strategic activities of startup at each stage. This study makes a contribution by helping us understand complicated process of funding and the successful strategic behavior of investor backed startups.
