A licensing approach for new fuel design is propose. It includes the possible licensing options to be taken according to the level of significance of design changes. This approach can be applied on legal grounds of the AEA, Article 44.3 and Article 21, but implies that the related ERAEAs should be revised or other alternative regulatory guidelines should be prepared. However, it is not intended to invoke additional requirements but rather to streamline and formulate the current practice by using one of supplementary provisions of the AEA, Article 104.2 which is recently enacted for approval of the technical report on a special topic.

In this study, two design examples of drilled shafts on soft ground in Ho-Chi-Minh City, Vietnam are introduced. One is for a 27-story apartment and the other is for a Arch bridge over Saigon river. Unlikely the normal cases in Korea, all of the bored pile foundations are supposed to be placed on soil layers. Therefore, skin friction between pile and ground is the most crucial design parameter. Three methods using SPT N value of sandy soil -Korean Road Bridge Code(1996), Reese and Wright (1977), and O'Neill and Reese (1988)- were adopted to obtain an ultimate axial bearing capacity. In order to verify the calculated bearing capacity, 3 sets of static load test and a Osterberg Cell test were performed at an apartment site and a bridge site respectively. LRFD (Load Resistance Factored Design) method was compared with ASD (Allowable Stress Design) method. On application of ASD method, safety factor for skin friction was adopted as 2 or 3 while safety factor for end bearing was 3. The design bearing capacities from ASD method matched well with those from LRFD method when safety factor for skin friction was adopted as 2.

The two major widely used building design code documents of reinforced concrete structures are the ACI 318-05 and Eurocode for the Design of Concrete Structures EC2. Therefore, a thorough comparative analysis of the provisions of these codes is required to confirm their validity and identify discrepancies in either code. In this context, provisions of flexural computations would be particularly attractive for detailed comparison. The provisions of safety concepts, design assumptions, cross-sectional moment capacity, ductility, minimum and maximum reinforcement ratios, and load safety factors of both the ACI 318-05 and EC2 is conducted with parametric analysis. In order to conduct the comparison successfully, the parameters and procedures of EC2 were reformatted and defined in terms of those of ACI 318-05. This paper concluded that although the adopted rationale and methodology of computing the design strength is significantly different between the two codes, the overall EC2 flexural provisions are slightly more conservative with a little of practical difference than those of ACI 318-05. In addition, for the limit of maximum reinforcement ratio, EC2 assures higher sectional ductility than ACI 318-05. Overall, EC2 provisions provide a higher safety factor than those of ACI 318-05 for low values of Live/Dead load ratios. As the ratio increases the difference between the two codes decreases and becomes almost negligible for ratios higher than 4.

Domestic and international laws and regulations on design of residential environment are adopted, revised and supplemented to solve the problems such as access, safety and privacy in the residential space of the elderly and the disabled. This study is an comparative analysis of Korea and Japan, USA, UK laws and regulations on environment design by literature review. The purpose of this study is to present the basic materials required for development of the standard that would supports the undiscriminatory physical environment for the socially weak who are experiencing aging and disability, due to the restricted scope of entrance, bathroom and kitchen spaces with high frequency of safety accident. The results of this study are as follows. (1) Design guidelines on residential environment were compared under five residential factors for aging in place: safety, accessibility, amenity, usability and privacy. (2) The guidelines of each country applied to the entrance, bathroom and kitchen space were compared. (3) The results showed present guidelines should be completed with 'safety', 'accessibility', 'amenity', 'usability' and 'privacy' for Aging in place.

최근 국토교통부는 실시설계 단계에서 설계의 안전성 검토를 실시할 수 있도록 건설기술진흥법을 일부 개정하였다. 설계의 안전성 검토에서 위험성을 판단하기 위해서는 단위작업별 재해의 발생빈도수와 심각성을 파악해야 한다. 따라서 본 연구에서는 ${\bigcirc}{\bigcirc}$ 공사의 건설재해자료(471건)를 24개 단위작업으로 분류하고, 각 단위작업별 재해발생 빈도수 및 심각성을 분석하였다. 그 결과를 토대로 단위작업별 안전관리 수준을 3개 그룹(특별관리, 중점관리, 상시 관리)으로 제안하였다. 본 연구결과는 건설공사에서 설계의 안전성 검토를 하는데 있어 기초정보로 활용될 수 있을 것이다. 또한 이 정보를 활용하여 재해발생률을 저감시킬 수 있을 것으로 판단된다.

본 연구는 해상풍력발전기 기초 설계에 사용되는 IEC 61400-3, DNV-OS-J101, GL Wind, EUROCODE, AASHTO 및 국내 설계기준의 설계방법 및 안전율의 정도를 비교, 분석함으로써, 국내에서 해상풍력발전기 기초 설계시 필요한 제반사항을 제공하고자 한다. 해상풍력발전기 기초 설계에 관한 국내외 설계기준을 분석한 결과 설계법은 크게 설계접근법, 하중저항 설계법, 허용응력설계법을 적용하고 있으며, 각 설계법에 따른 안전율 정도를 분석한 결과 하중저항계수 설계법과 설계접근법은 거의 유사한 수준의 안전율을 확보하고 있는 반면, 허용응력설계법에서는 다소 보수적인 안전율을 적용하고 있어 해상풍력발전기 기초의 경제적 설계를 위한 국내 설계기준 개발이 필요할 것으로 판단된다.

In usual safety signs are final means to transmit hazard information so that the importance of them cannot be emphasized too much. Nevertheless, in Korea, few people are interested in functions of safety signs so that evaluation of safety signs are seldom committed. This research was conducted to evaluate and compare perceptional characteristics of safety signs, especially "Fall" signs, by Semantic Differential Method and Multi-dimensional Scaling Method, with undergraduate students as well as industrial workers. According to research results on several signs evaluated high through suggested procedure, action inducibility was different for students majoring in different sciences, but it had common elements in the sense of 'openness' or 'arrangements'. Besides, perceptional images on safety signs were mainly recognized with bases of 'arrangement' for student group and 'simplicity' for industrial workers, respectively, and their maps corresponded well with each other by partial rotating so that students and workers seemed to recognize safety signs with similar factors though their name might be different. However, since perceptional characteristics including image map, comprehensibility, and action inducibility were similar for student group whereas those were not for worker group, it was concluded that the test for action inducibility would be absolutely necessary for safety signs for workers' group.
