Then 3D printing is used practically at construction sites, there is a serious lack of studies on the conflict with construction-related laws and expected operational problems. Accordingly, the purpose of this study is to present obstacles and directions for improvement in construction-related laws (Building Act, Construction Technology Promotion Act, Housing Act, Construction Machinery Management Act, etc.) for practical operation of 3D printing. The important results are as follows. Amending existing construction-related laws for 3D printing is irrational and inefficient in terms of structure and material. This study proposed a method of satisfying performance required by laws or standards based on the performance design method presented in existing laws and systems through structure and material performance certification procedure. In addition, inclusion of 3D printing equipment in the Construction Machinery Management Act results in various restrictions such as equipment inspection and certification of machine parts. As such restrictions can block vitalization of 3D printing, a long-term and step-wise approach was suggested.

The durability prediction of emission control components, especially 02 sensor and catalytic converter, is getting more important as emission regulation is getting stricter and vehicle durability mileage requirement is also extended from 80,000 ㎞ to 160,000 km in Korean market. And the duration of vehicle mileage accumulation to get vehicle exhaust emission deterioration factor for certification is required to be shorter in order to reduce the vehicle development time. Since most of the vehicle emission development tests are done on chassis dynamometer and aging bench by using vehicle aging modes, real road condition and in-use driving patterns must be reflected into them to predict the vehicle emission level and to meet emission regulation especially at high mileage. In order to get the frequent driving pattern of vehicle and the aging characteristic of emission components, a vehicle was tested by changing drivers and driving roads around Seoul. Real road driving patterns were analyzed and compared with those of the certification modes which are well known in automotive industry.

As information system is getting higher and amount of information assets is increasing, skills of threatening subjects are more advanced, so that it threatens precious information assets of ours. The purpose of this study is to present a strategic direction for the types of companies seeking access to information security. The framework classifies companies into eight types so company can receive help in making decisions for the development of information security strategy depending on the type of company it belongs to. Paired comparison method survey conducted by a group of information security experts to determine the priority and the relative importance of information security management elements. The factors used in the security response strategy are the combination of the information security international certification standard ISO 27001, domestic information protection management system certification K-ISMS, and personal information security management system certification PIMS. Paired comparison method was then used to determine strategy alternative priorities for each type. Paired comparisons were conducted to select the most applicable factors among the 12 strategic factors. Paired comparison method questionnaire was conducted through e-mail and direct questionnaire survey of 18 experts who were engaged in security related tasks such as security control, architect, security consulting. This study is based on the idea that it is important not to use a consistent approach for effective implementation of information security but to change security strategy alternatives according to the type of company. The results of this study are expected to help the decision makers to produce results that will serve as the basis for companies seeking access to information security first or companies seeking to establish new information security strategies.

본 논문은 주민등록번호 대체수단의 발급·이용 시 신원확인 및 인증절차에 대해 현황을 분석하고 문제점의 개선 방안을 제안한다. 본인확인서비스 이용 과정에서 이용자의 개인정보보호와 권리보장이 필요하지만 근래에 만연해 있는 본인확인서비스의 확대로 인해 무분별하게 본인확인을 요구하고 있으며, ISP들도 신원확인 및 인증절차의 문제점 개 없이 활용에만 그치고 있다. 결국 온라인 서비스 이용자들은 자신의 개인정보가 과도하게 제공되고 있으며, ISP들은 본인확인서비스 요구에 따른 과금이 발생하고 있고 결국 온라인 서비스에 그 비용이 부가되고 있다. 따라서 본 논문에서는 주민등록번호 대체수단 발급·이용 시 이용자의 신원확인 및 인증 절차의 현황을 분석하고 문제점 개선방안을 제안한다. 제안한 방안을 통해 온라인 서비스 이용자들의 개인정보보호와 ISP들의 비용 절감, 그리고 온라인 서비스의 활성화를 꾀할 수 있을 것이다.

Although interest in eco-friendly fashion products is increasing among scholars and industry leaders, the concept of eco-friendly products remains unclear, preventing consistent assessment of which fashion products are eco-friendly. This study conducted a content analysis of eco-friendly product information from 87 domestic and 102 foreign brands to reveal key standards for categorizing eco-friendly fashion products. Product characteristic information was coded according to the four material-based standards (i.e., organic material, regenerative material, alternative material, and sustainably produced/upcycled material). Consistency between coders was confirmed by Cohen's kappa. In results, eco-friendly fashion products are categorized by four material-based standards and two certification standards (i.e., certified, not certified). Among the four material-based categories, the greatest number of domestic and foreign companies produced eco-friendly products that were classified as the regenerative material group. In addition, companies acquired eco-friendly certifications related to the use of organic, regenerative, and alternative materials. The greatest number of eco-friendly material brands used for eco-friendly fashion products belonged to the regenerative material group. Based on the study results, a typology of eco-friendly products was suggested. This typology can benefit practitioners and academics by highlighting a need for classification system for the eco-friendly fashion products, as well as by providing insight into the categorization of eco-friendly fashion products.

세계적으로 그린빌딩, 스마트빌딩 등과 같은 마이크로 워터 그리드 단위의 초고층 빌딩이 증가되는 추세로 수자원과 에너지의 수요증대 등과 같은 문제를 해소하기 위해 그린빌딩 인증 제도가 시행되고 있다. 그러나 마이크로 워터 그리드 단위의 그린빌딩 인증제도 내에서 전력과 에너지 분야는 활발한 연구개발사업이 진행되고 있는 반면 수자원의 연계·연속 활용을 통해서 물의 재이용, 물 절약 등과 같은 지속가능한 수자원의 활용에 대한 연구는 다소 미흡한 상태에 있다. 따라서 본 논문에서는 그린빌딩 인증제도에서 다중수원의 연계연속 활용을 위해 수자원 부문에 대한 특성과 한계점을 분석하고, 마이크로 워터 그리드 단위의 그린빌딩이나 스마트빌딩 및 복합단지 내외에서 상수, 자연 및 대체수자원 등과 같은 각종 수자원이 연계연속 활용할 수 있는 평가방법과 성능평가기준을 제시하고자 한다.

최근 전자서명법 개정으로 인해 공인인증서(현. 공동인증서) 지위가 만료됨에 따라 전자서명 기반의 공인인증서도 주민등록번호 대체수단에서 지휘가 상실되었다. 이로 인해 공인인증기관들은 방송통신위원회로부터 주민등록번호 대체수단 기반의 본인확인기관 지정심사를 통해 본인확인서비스 제공 기관으로 최근 지정받은 바 있다. 하지만, 기존의 주민등록번호 대체수단인 아이핀, 휴대폰, 그리고 신용카드들과 달리 인증서 발급 신청자의 신원확인 절차가 기존 대체수단들과는 상이한 부분이 존재하고 있다. 특히, 발급 신청자의 신원을 등록대행기관이 수행하고 있다. 본 연구에서는 전자서명 기반의 본인확인서비스 제공 시 대체수단 발급 과정에서 신원확인, 허무인 확인, 신원보증인 확인 등에 대한 개선방안들을 제안한다. 제안한 방안은 전자서명 기반의 본인확인서비스에 적용함으로써 이용자 개인정보보호와 보편·타당하고 안전한 본인확인서비스 제공이 가능함을 알 수 있다.

As the expension of metropolis and increasing of housing site, GIL(Gas Insulated Line) comes to the fore as an alternative to overhead transmission line avoided by local resident. The certification and experimental test for the GIL is now in progress in under ground test lab, Go-chang. For the test, we propose a method of PQ(pre-qualification) test which is essential for development and field application in this paper. The test following this method take about 200 days or 300 days under the circumstances.
