In this paper, there are several analysis on G-SEED, Building Energy Efficiency Rating System, Energy Performance Index, Energy Saving Plan about how they are applied by classification and planning standard. The analysis result found out that G-SEED has low select percentage by having difficulties to managing and additional cost when the each class is selected. And also, Building Energy Efficiency Rating System in school is planed in comparably simple design and similar size and also mostly uses high efficient machines, which was in high lever comparing to the system in facilities in other uses. In the case of EPI, there are differences on acquiring grades by each region. Especially, Gyung-gi region has a low grade on architecture part comparing to other parts, which seems to acquire more grades by strengthen insulation performance. By the result from the three standards, many facilities has only formal plan to pass the required standard without considering specialities of each buildings, which has a tendency to have a pattern to have a minimum criteria. However, School has a symbolic building which has a obligation to be the base of the aim for growing green energy buildings and green education for students. Therefore, planning with understanding of specialities of the facility, having various and rational evaluation standards from the planning of the building is necessary.

On June 24, 2015, the Financial Services Commission (Financial Services Commission) completely abolished the security review process, and said that it would substitute self-security review obligations with self-security reviews. Security officials at financial institutions conduct security reviews based on CIA security grade when they conduct security reviews for secure electronic financial transactions. However, the recent security review for Internet and mobile electronic financial transactions has carried out a security review, either by checking separate processes or by referring to new technologies and data related to security. This paper proposes the CIAAP security gradesl with the addition of certification and privacy protection indicators to the CIA based security grades, especially through the security review of electronic financial transactions.

Purpose: This study investigated customers' perception of a hygiene grade certification system for restaurants and this study also determined way to promote the application of the hygiene grade certification. Methods: A total of 315 customer responses were used for the data analysis. Statistical analyses were conducted using the SPSS program (ver. 23.0) for frequency analysis, χ²-tests, t-tests, analysis of variance, and Importance-Performance Analysis (IPA). Results: The composition of the respondents was 43.8% males and 56.2% females. The 73.3% lived with their families while 26.7% lived alone. Among those surveyed, 84.5% dine out at least once a week and 66.8% dine out during weekends evening. In addition, the most preferred types of restaurants were Korean restaurants (37.5%), delivery restaurants (14.6%), and Western restaurants (8.9%). Information about restaurant was most frequently obtained through Internet searches (54.0%). The average expenditure of eating-out per person was 15,483 Korean won, and the overall satisfaction averaged 3.58 out of 5 points. According to the results of IPA, the restaurant selection attributes that were priorities for improvement were the foods' taste and restroom cleanliness. In addition, 30.5% of respondents recognized the hygiene grade certification system for restaurants. The intention of dining at restaurants with a hygiene grade certification in the future was on average 4.02 out of 5 points. A total of 56.8% of respondents were willing to pay more for a restaurant with a hygiene grade certification. The average percentage of additional price was 6.02%. Conclusion: In order to apply and quickly disseminate the hygiene grade certification system all over the Korea, the study results suggest that relevant policy should be provided by the Korean government for certified restaurants along with the relevant education and promotion of the system to customers.

A various building certification systems are being enforced in Korea. However, the enforcement of many building certification systems has brought on the concerned people's confusion and the operation of various building certification systems which have similar assesment items causes much time and economical losses. Therefore, in this paper, the features of the GBCS(Green Building Certification System), Housing Performance Indication System, Building Energy Rating System, and Green Home Standard and Performance Evaluation System are compared and the correlations among each building certification system are analysed. As a result, it is presented that a considerable number of assessment items were so similar and identical that integration of building certification systems is needed for effective operation of these systems.

In the case of electronic payment, the obligation to use the certificate-based authentication was abolished. As Fin-tech service providers gain autonomy, various authentication methods are provided. SMS, ARS, PIN, Text-passwords, Fingerprints are popular authentication methods in the mobile Fin-tech services. In this study evaluate the usability and security of authentication methods in a unified mobile environment. We evaluate the usability through SUS and interview. Also we evaluate the security level of authentication methods through NIST guideline. At the result of the usability evaluation, Fingerprint authentication method had been determined as the highest usability, also Fingerprint authentication method had been determined as the safest authentication method by obtaining Security Level 4.

컴퓨터 기술의 발전으로 정보화 시대를 맞이한 현대에 있어서 “보안 기능의 정형화 설계 방법 연구”는 정보 보호와 완벽한 보안 때문에 매우 중요하다. 이러한 추세에서 전 세계적으로 보안 시스템에 대한 등급을 나누고 있고, 국내에서도 한국정보보호센터에서 침입차단시스템에 대해 K1에서 K7까지의 등급을 매기고 있다. 이 등급을 살펴보면 정형 언어를 사용하여 시스템 명세를 수행하여야만 K5이상의 고 등급을 획득할 수 있다. 또한 최근에 들어서 소프트웨어 개발 방법에 객체지향 방법론이 많이 사용되고 있는 시점에서 이러한 방법론으로 개발되는 시스템에 대한 정형적인 설계방법이 필요하다. 본 논문은 실제 간단한 규모의 보안 시스템 설계에 직접 적용될 수 있는 수준의 정형기법을 제시하는 것을 목표로 한다. 여기서는 passive attack에 대해 사용자의 패스워드를 보호하기 위한 간단한 스킴이 S/KEY 인증 시스템에 객체지향 정형명세언어인 ZEST와 UML을적용해 본 결과를 기반으로 보안 시스템을 정형 명세한 경험을 기술한다.
