  • Quick and accurate understanding of the situation in a severe accident is essential for conducting the appropriate accident management and response using the accident diagnosis information. This study employed deep learning technology to diagnose severe accidents through the major safety parameters transferred from a nuclear power plant (NPP) to AtomCARE. After selecting the major accident scenarios to consider, a learning database was established for particular scenarios affiliated with major scenarios by performing a large number of severe accident analyses using MAAP5 code. The severe accident diagnosis technology, which classifies detailed accident scenarios using the major safety parameters from NPPs, was developed by training it with the established database . Verification and validation were conducted by blind test and principal component analysis. The technology developed in this study is expected to be extended and applied to all severe accident scenarios and be utilized as a base technology for quick and accurate severe accident diagnosis.

  • The e-Government standard framework provides overall technologies such as reuse of common components for web environment development such as domestic government/public institutions, connection of standard modules, and resolution of dependencies. However, in a standardized development environment, there is a possibility of updating old versions according to core versions and leakage of personal and confidential information due to hacking or computer viruses. This study directly analyzes security vulnerabilities focusing on websites that operate eGovFrame in Korea. As a result of analyzing/classifying vulnerabilities at the internal programming language source code level, five items associated with representative security vulnerabilities could be extracted again. As a countermeasure against this, the security settings and functions through the 2 steps (1st and 2nd steps) and security policy will be explained. This study aims to improve the security function of the e-government framework and contribute to the vitalization of the service.

  • With increasing interest of health due to population aging, medical device industry is highlighted as a promising industry. However, Korea medical device industry is not enough market competitiveness compared to global company due to a narrow domestic market and a small company structure. In order to retain the national competitiveness, it is necessary that we have to derive a central technology and its trend. This study has predicted a central technology for medical device industrial using patent network analysis. The central technology is defined as a key technology that is connected to most other technologies and that significantly affects them. For the empirical study, we conducted social network analysis using covariance and correlation coefficient between IPC codes extracted from medical device patents, introduced by Jun(2012). A social network is a social structure of diverse items as well as of human beings. In this study, we set each medical device as a node in an SNA and analyze the Degree values between them. Also, Korea health industrial statistics system are utilized for verification of selected central technology. As a result, we found that the central technology is located on the medical device items, which are listed higher the amount of production. The central technology selected through the proposed methodology will provide a inspiration for establishment of R&D policy.

  • Klaus Schwab's discussion on the Fourth Industrial Revolution provides a framework for predicting the direction of legal technology development. Technological convergence, which has emerged as the core concept of the Fourth Industrial Revolution has a significant effect on legal technology. In particular, various new technologies, such as legal chatbots and platforms, are being introduced to enhance efficiency and accessibility in the legal field. However, legal technology is still in its early stage, with institutional improvement needed to vitalize the industry. In this paper, we first specify the concept and classification of legal technology in Chapter 2, followed by trends and limitations in Chapter 3 and ways of vitalizing legal technology in the future in Chapter 4. To invigorate legal technology development, it is necessary to put in place legal regulatory measures that stipulate the active disclosure of legal data, such as precedents, and make free use of such measures. In the law, many issues, such as the safety of artificial intelligence, personal information protection, and ethical standards, will be discussed in the future. Therefore, via this paper, we hope to promote the formation of social consensus and prepare countermeasures, such as legislative measures.

  • This paper analyzed the restrictiveness of the rules of origin of the 15 FTAs of Korea utilizing the restrictiveness index suggested by Estevadeordal(2000). The main purpose of the paper is to provide an update of the current status and characteristics of the restrictiveness of the rules of origin based on product type and country. The research showed that FTA with EU and Turkey showed the highest restrictiveness, whereas New Zealand, Peru and India showed the lowest. Overall, Korea's restrictiveness index was found to be at appropriate levels. Additionally, in terms of the current status by restrictiveness index, over time with the exception of European countries in the FTA, products with the lowest score in restrictiveness index of 2 continued to be processed in the Korea-Peru FTA which illustrated the current trend of easing restrictiveness. In terms of restrictiveness index based on product type, commodity products, processed food, clothing-fabric-general merchandise were found to be very strict. However, in categories such as general machinery, electronics, chemical products and precision instruments, the restrictiveness index showed the lowest readings. The results imply the high restrictiveness in sensitive products that are vulnerable from competition through high tariffs, and easing of restrictiveness in competitive products in order to vitalize trade. The results also show that in Korea's FTA, Korea's rules of origin in FTA vary and are sorted in a complicated manner. With an increasing number of FTAs and a number of different rules of origin, there is a need for standardized criteria for Korea. This study was significant in that it compiled all the rules of origin and the restrictiveness index of all FTAs that came into effect and have been negotiated in Korea. The results of the research are expected to be used as an informative and meaningful guideline for Korea's FTAs.

  • This study analyzed the registration of patent and utility models by fashion firms in Korea. A total of 2,291 registration cases of IPC A41B-H from the period of 1996 to 2009 were collected by KIPRIS of the Korean Intellectual Property Organization (KIPO). All cases were analyzed by year to review the longitudinal trend and 481 cases of IPC A41B (shirts, underwear, baby linen, and handkerchiefs) and 1088 cases of IPC A41D (outerwear, protective garments, and accessories) were analyzed by content (provided benefit type and developing method), by detailed product items and the characteristics of the applicant. The results of this study were as follows: 1) Registration of IPC 41 increased steeply by the year (especially since 2006) and the patent registrations increased more than those in the utility model. 2) Analyzing the application content of A41B on the basis of benefit showed that 75% were to provide new functions and the rest were for health. In terms of the developing method, 83% of benefit provided by the application were by design development, 11.2% were by material, and the rest was by process, In the cases of IPC A41D, 23.6% were for safety and protection. In terms of the developing method, the process and material development were more frequently adopted than in the cases of A41B. 3) The major product types of A41B were socks, underwear, and infant wear, whereas gloves and parts of clothing were major items in A41D. 4) In terms of the characteristics of the applicant, registration by firms was greater for patents than for utility models and registration by foreigners increased in 2006 due to the complete opening of the retail market. 5) Fifteen universities registered for a total 57 cases and major applications were for IT related clothing or high-tech protective items.

  • Recently, in Korea, a few construction companies have been tried to develop a management system, which is able to integrate schedule and cost. In spite of these attempts, however, advanced management techniques can be hardly applied under the BoQ based management system. In order to improve these problems, many studies have been peformed, but yet could not overcome practical limitations. Besides, the application of historical data is below the level since it is so difficult to accumulate and feed-back historical data under the unique character of construction industry. Consequently, lots of time and effort have being wasted to establish control criteria. The newly generated Information is not systematically managed as well. Therefore, this study suggests Integrated Construction Management System complemented the existing practical problems.

  • 레이저 가공기술은 재료가공 분야에서 넓은 응용분야를 가지고 있으며, 특히 절단, 용접, 열처리 등의 가공분야에서 고정밀도와 자동화의 용이성으로 인해 생산성이 높은, 고부가가치의 첨단응용 기술로 부각되고 있다. 특히 레이저절단은 타 절단법에 비교되는 절단정도, 열영향, 생산성, 작업 환경등의 각종 우위성으로 박판 및 후판절단분야에서 급속한 보급을 보이기 시작하였다. 현재 대 부분의 레이저 가공기는 CNC화 되어가고 있는 추세이며, 레이저 절단의 경우 생산성증대 및 고 정밀화를 위하여 CAD/CAM인터페이스에 의한 자동화가 필연적인 상황이다. 뿐만아니라 고출력 레이저 발전기를 가공 기본체에 탑재한 탑재형 레이저가공기의 출현으로 대형부재의 절단이 가능 하게 되었으며, 더불어 절단공정의 무인화를 지향하는 각종 시스템이 개발되고 있다. 이와 같은 무인화, 생산성증대, 작업시간단축과 러닝 코스트 및 재료의 절감을 위한 노력의 일환으로 컴 퓨터에 의한 자동 및 반자동 네스팅 시스템의 개발을 들 수 있다. 레이저에 의한 2차원 절단응 용분야에서의 네스팅작업은 설계가 끝난 각 부품의 절단작업의 전단계로서 수행되며, 일반적으로 네스팅공정이 완료되면 절단경로를 결정하고 가공조건과 함께 수치제어공작기계의 제어에 필요한 NC코드를 생성하게 된다. 최근에는 이와 같은 네스팅 시스템이 일부 생산현장에 적용되고 있 으나 이러한 시스템들의 대부분이 외국에서 개발된 것을 수입하여 사용하는 실정이다. 2차원 패턴의 최적자동배치문제는 비단 레이저 절단과 같은 열가공 분야에서 뿐만 아니라 블랭킹 금형, 의류, 유리, 목재등 여러분야에서 응용이 가능하며 패키지의 국산화가 시급한 실정이다. 네스 팅작업은 적용되는 분야에 따라 요구사항과 구속조건이 달라지며 이로 인해 알고리즘과 자료구 조도 달라지게 되나 공통적인 목표는 주어진 영역안에서 겹침없이 배치하면서 버림율을 최소화 하는 것이다. 지난 10여년간 여러 산업의 응용분야에서는 네스팅시스템의 도입이 활발하게 이 루어지고 있는데 수동에 반자동 및 자동에 이르기까지 다양하나 자동네스팅시스템의 경우 배치 효율의 신뢰성이 비교적 부족하기 때문에 아직까지는 생산현장에서 기피하는 실정이다. 배치알 고리즘의 관점에서 볼 때 이러한 문제들은 NP-complete문제로 분류하며 제한된 시간안에 최적의 해를 구하기가 가능한 조합 최적화 문제로 알려져 있다. 따라서 이 글에서는 레이저 절단분야 에서의 네스팅시스템에 관한 개요와 최근의 연구동향 그리고 몇 가지 전형적인 네스팅 알고리 즘들을 소개하고 비교분석을 통해 개선점을 간략하게 논의하고자 한다.

  • 고석하 등(2002)은 인터넷 소매상이 상품 품목의 명목 가격과 배송료를 이용해서 고객의 일회 총 구매 비용을 조절한다는 것을 밝혔다. 고석하 등(2002)은 같은 내용의 상품 조합을 인터넷 시장에서 구매하기 위한 비용과 전통 시장에서 구매하기 위한 비용을 비교하였다. 분석 결과, 그 교호작용과 함께, 상품 종류와 일회 구매액/가격의 크기의 두 요소가 인터넷 시장의 전통 시장에 대한 총 구매비용 할인율의 변동의 약 60%내지 80%를 설명할 수 있다는 것을 보여주었다. 한편, 구매액/가격은 인터넷 시장에서의 해당 산포도(전통 시장의 그것에 대비한)에는 거의 영향을 미치지 못하며, 상품의 종류도 산포도에는 할인율에서와 같이 큰 영향을 미치지 않았다. 인터넷 시장의 가격이나 구매비용 산포도는 상품 특성이나 구매액 크기 이외의 다른 요인에 의해서 주로 영향을 받는 것으로 나타났다. 따라서, 본 논문에서는 가격 요인 이외의 경제적 경쟁요인에 관한 실증연구로서, 2002년 6월 17일부터 20일까지, 소프트웨어, PC와 주변기기, 휴대폰, 가전제품, CD, 화장품, 그리고 책의 7가지 산업 전문 쇼핑몰과 종합 쇼핑몰을 대상으로, 인터넷 시장에서 수행되고 있는 경제적인 비 가격 경쟁요인에 관한 실증 조사를 실시하였다. 조사 결과, 인터넷 시장에서 수행되고 있는 경제적인 비 가격 경쟁요인은 매우 다양하며, 상품별로도 다른 특성을 보이고 있는 것으로 밝혀졌다. 인터넷 소매상의 경제적인 비 가격 경쟁요인은 크게 배송료 면제와 배송료 외 인센티브 제도로 구분된다 본 논문에서는 경제적인 비 가격 경쟁요인의 모든 경우의 수를 고려할 수 있도록, 코드표를 작성하여 정리하고 분석하였다.전체 분석정보의 공유가 필수적으로 발생하게 됨으로, 유전체 정보와 임상정보의 통합은 미래 의료환경에 필수기능이 될 것이다. 3) 각 생명공학 연구소에서 사용하는 첨단 분석 장비와 생명공학 정보시스템의 자동 연계가 필요하다. 현재 국내에는 전국적인 초고속정보망이 가동되어 웹을 기반으로 하는 생명정보의 공유는 기술적으로 문제가 될 수 없으나 임상정보의 유전체연구에 그리고 유전체연구정보의 임상활용은 다양한 문제를 내포하고 있다. 이에 영상을 포함한 환자정보의 유전체연구센터와 병원정보시스템과의 효율적인 연계통합 운영을 위해 국내에서는 초기 도입단계에 있는 국제적인 보건의료정보의 표준인 Health Level 7 (textural information 공유), DICOM (image 및 wave 공유), 관련 ISO표준, WHO의 ICD9/10 (질병분류), LOINC (검사 및 관련용어), SNOMED International (의학용어) 등을 활용하여야 한다.matrix.
