본 논문에서는 증강현실기술을 사용하여 재난 대응 훈련에서의 효과성을 높이기 위한 시뮬레이터 개발용 시나리오의 작성에 대해서 소개하였다. 기존의 재난 대응 훈련은 시나리오의 비현실성, 훈련내용의 부실로 인한 실효성의 부족 등의 문제로 인하여 효과성 측면에서 문제가 제기되어 왔으며, 세월호 사건은 그러한 문제점이 직접적으로 드러난 재난으로 꼽히고 있다. 점차 다양화, 복잡화되는 재난에 따라 실질적인 훈련과 다양한 기능, 부처간 연계를 위한 훈련체계가 요구되는 현실에 맞춰 재난대응에 있어 통합훈련의 필요성이 대두되고 있다. 시뮬레이터에 사용되는 시나리오는 단순한 도상훈련이 아닌 직접 체험할 수 있다는 점에서 기존의 훈련 시나리오와는 다른 성격을 가지며, 실효적 재난대응을 위해 국내 외 사례에서 기반한 재난대응의 문제점을 분석하고 그것을 집중적으로 훈련할 수 있도록 하고 있다. 또한 여러 돌발적인 이벤트 상황이 발생하더라도 그에 적절한 대응방안을 함께 제시하고 있다.

A renovation project of apartment housing is generally divided into four stages: Project inquiry stage, planning and feasibility stage, design stage and construction stage. Currently, procedure and managerial technique for a remodeling project has not been systematically established so that many companies have difficulty in doing their business. In particular, the design stage in participant which a project managers, designers, residents and engineers is more complicate than the other stages in terms of roles and working procedure. The design documents can be found trial and error if it is not well managed. The insufficient design caused by lack of ability to efficiently utilize information obtained during the stage and inappropriate decision-making not only results in diverse problems in the construction stage but also makes people suspect satisfaction and reliability on the remodeling improvements. Therefore the design stage is very significant issue on the renovation project. As the consequence, the design stage of a remodeling project is so important that it should be carefully managed, and composite understanding of the process to be executed. To do this, we provide roles and responsibility of each participant in the design stage and analyze the process where information is utilized in design stage. The information is analyzed in terms of input, tool and output.

After the financial crisis in 2008, the financial market still seems to be unstable with expanding the insolvency of the financial companies' real estate project financing loan in the aftermath of the lasted real estate recession. Especially after the illegal actions of people's financial institutions disclosed, while increased the anxiety of economic subjects about financial markets and weighted in the confusion of financial markets, the potential risk for the overall national economy is increasing. Thus as economic recession prolongs, the people's financial institutions having a weak profit structure and financing ability commit illegal acts in a variety of ways in order to conceal insolvent assets. Especially it is hard to find the loans of shareholder and the same borrower sharing credit risk in advance because most of them usually use a third-party's name bank account. Therefore, in order to effectively detect the fraud under other's name, it is necessary to analyze by clustering the borrowers high-related to a particular borrower through an analysis of association between the whole borrowers. In this paper, we introduce Analysis Techniques for detecting financial loan frauds in advance through an analysis of association between the whole borrowers by extending SNA(social network analysis) which is being studied by focused on sociology recently to the forensic accounting field of the financial frauds. Also this technique introduced in this pager will be very useful to regulatory authorities or law enforcement agencies at the field inspection or investigation.

The purpose of this study is to verify the factors affecting survival time by estimating survival rate and survival time using non-financial information of social enterprises using credit guarantee in credit guarantee institutions, and provide information to stakeholders to improve survival rate and employ to contribute to maintaining and expanding the As a research method, survival analysis was performed using a non-parametric analysis method, Kaplan-Meier Analysis. As a sample, 621 companies (577 normal companies, 44 insolvent companies) established between 2009 and 2018 were selected as the target companies. As a result of examining the factors affecting survival time by classifying social enterprise representative information and corporate information, representative credit rating, representative home ownership, credit transaction period, and corporate credit rating were derived as significant variables affecting survival time. In the future, financial institutions will be able to induce corporate soundness by reflecting factors that affect survival when examining loans for social enterprises, contributing to job retention and reduction of social costs. Supporting organizations such as the government and private organizations will be able to use it in various ways, such as policy establishment and education and training for the growth and sustainability of social enterprises. With this study as an opportunity, I hope that research will continue with more interest in the factors influencing social enterprise performance as well as corporate insolvency.

비공개기업이 상장할 수 있는 방법은 신규상장(IPO)과 기존의 상장기업을 인수하여 소위 우회상장을 하는 방법이 있다. 전자는 제도에 의한 자본시장 진입인데 반해 후자는 시장거래에 의한 자본시장 진입이라는 점에서 후자가 시장원칙에 가깝다고 할 수 있다. 그럼에도 불구하고 상장사 인수는 부실기업이 자본시장에 진입하는 것을 차단할 수 있는 심사기능이 약하고, 시장진입 시 정보를 시장에 제공하는 정보기능이 약하다는 가정에 기초하여, 신규상장에 비해 비효율적이라는 주장이 제기될 수 있다. 따라서 상장사 인수가 신규상장에 비해 비효율적인 시장진입 방식인가에 대해서는 실증적인 고찰이 필요하다. 본 연구에서는 상장사 인수의 경우 상장사 기존주주의 부가 훼손되고, 신규상장에 비해 정보의 효율성도 떨어질 것이라는 가설을 세우고 실증분석을 해 보았다. 이를 위해 $2000{\sim}2005$년 6윌 기간에 비공개기업이 상장사 경영권을 인수한 사례를 가지고, 인수공시 전후의 비정상수익률을 측정하여 주주의 부에 미치는 영향을 측정하였다. 또한 인수공사일 종가를 시초가로 하는 향후의 장단기 초과수익률을 측정하여 이를 토대로 시장진입일 배포된 정보가 효율적이었는지를 알아보았다. 그리고 각각의 상장사 인수 사례에 대해 같은 시기, 같은 산업, 같은 시장에서 신규로 상장했던 종목을 모아 매칭샘플을 만들고 상장사 인수 샘플과 비교분석하였다. 그 결과 상장사 인수 시 상장사의 기존주주는 유의적인 자본이득을 향유함이 밝혀졌고, 정보의 효율성도 신규상장에 비해 유의적으로 낮다는 일관적인 증거를 찾지 못하였다. 다만 상장사 인수가 무자본 인수의 형태를 취할 때는 시장의 주의가 요망된다.

The "Information and Communication Technology Education Guidelines" were revised in December, 2005. However, the revised guidelines are not propagated in the elementary school. One of the reasons is that the textbook is not faithful to the revised guidelines. We analyzed the elementary computer textbooks published on and after June 2006. In the result, the contents of many textbooks are not based on the "Information and Communication Technology Education Revised Guidelines". Especially, "Understanding of the Information Processing" and "Comprehensive Activities" areas are not faithful to the revised guidelines. Therefore, the systematization of the textbook screening system, participation of the computer education expert, development of the detailed curriculums, and training of the elementary teachers are essentials for invigorating of the elementary computer education.

Although the demand for histopathological examinations has been increasing, medical accidents in management of specimens also have been increasing because most of the examinations are processed manually which can cause careless handing, confusing information and mismatching during the procedure. In the future, histopatological examination will be used frequently for handing incurable diseases and verification of new drug. Thus, efficient and error-free management system for handling personalized medical history and test results is infallibly necessary. In this paper, I have proposed an integrated printing system for informatization of histopathological examination that support the u-Healthcare environment based on RFID in near future. The proposed system supports systematization of whole examination process and information of pathological samples. This system will contribute to reduction of costs, improvement of operational efficiency, and mostly fundamental prevention of medical accidents.
