In this paper, the illuminating optics of asymmetric light distribution was studied, which allowed the light distribution to be uniform even for short-range irradiation on a wide illumination area. In the case of a light installed at a short distance, the light is not diffused enough because of the short irradiation distance. For this reason, it is difficult to satisfy uniformity of illumination. In addition, lighting design for asymmetric distribution is required because the lighting device is installed tilted, for visibility. Therefore, the design of lighting systems with asymmetric light distribution could achieve uniform illumination of the target surface even under short-distance irradiation. This was then applied to the license lamp, a lighting system featuring short light irradiation distance, to confirm that it satisfies the legal standards.

In this study, the budget investment state of the technology classification structure in a fire-fighting and safety research development program and the capability of a fire-fighting safety research program were analyzed between 2007 and 2013 with support from the ministry of public safety. The Ministry of public safety and security's fire safety research funding has shown a gradual increasing tendency. More 80% of the budget was invested in fire safety and disaster response technologies and the fire safety and special disaster prevention response technology of R&D. From the results of analyzing the capacity of fire-fighting safety and rescue safety, it was found to have a moderate level of 3.5 on a 7 point scale basis. To develop the Ministry of Public Safety and Security's fire safety research in the future, the flexibility and reasonableness of the budget/legal/institutional framework and support should be ensured to improve the operational capability of resources. In addition, a proliferation program is necessary for the commercialization and industrialization of research results.

In modern society the population of disabled goes on increasing rapidly not only in congenital deformities but also in acquired handicapped persons due to various factors such as car accidents and industrial disaster. And the number of disabled passengers in airports is growing every year with economic growth and globalization in Korea as well. That is the reason why the effort to the convenient facilities for the disabled in airports is needed more. The real situation in airports which are the public buildings is that the effort to install the facilities for the disabled is only perfunctory to meet the legal standard and cannot answer to the expectation of the facilities for e disabled. In this investigation I would like to give the airport operators the guide line to expand the facilities and the disabled an opportunity to use airports more freely and conveniently through the presentation on the problems and solutions with the current situation of the facilities for the disabled and the satisfaction of users in all airports in Korea.

As the further development of economic globalization and the continued opening up of international construction markets, many of the countries are faced with more and more severe domestic and international construction market competition. It has been a focus question of all the countries and regions that how to achieve maximal profit in the international construction market, but construction claims are growing into a stumbling block to the project participants to reach their expected goals. Thus, the management of construction claims is considered as the greatest challenge that is facing constructors in today's vacillating business environment. Recently, many of the methodologies have been developed for the construction claims to overcome these current problems, but compared to the developed countries there is still a big gap in some Asian countries, such as China and Korea. This paper attempted to investigate and compare the project claims system in these two countries to figure out the common points and differences.

In spite of economic slump, the Real Estate PF(project financing) market competes for receiving large project orders. While the project is successful, the Real Estate PF still guarantees a high benefit ratio. But the initial stage of the project involves many risks. There are many financial, constructional, legal, and other risks. After searching for possible risks, we must consider a management plan. This study executed a question investigating risk factors and management plans. Those who have studied for 3 or more years have concluded that the question objects are developer, construction company, and financial institution staff. The main management plans take actions for proper benefit rate security and loan repayment. This study has also been verified through the actual case. The study results will help solve the Real Estate PF project's risks.

Small and medium-sized companies lack countermeasures to secure the safety of a information system. In this circumstance, they have difficulties regarding the damage to their images and legal losses, when the information is leaked. This paper examines the information leakage of the system and hacking methods including APT attacks. Especially, APT attack, Advanced Persistent Threats, means that a hacker sneaks into a target and has a latency period of time and skims all the information related to the target, and acts in the backstage and neutralize the security services without leaving traces. Because he attacks the target covering up his traces not to reveal them, the victim remains unnoticed, which increases the damage. This study examines attack methods and the process of them and seeks a countermeasure.

Using ArcGIS Model Builder, with emphasis on the importance of ecology and user friendliness, a model for site selecting tool is developed. This tool is developed by establishing standardized method for data selection and analysis with evaluation criteria using GIS. For this task, our first action was to objectively define and establish 18 elements to evaluate the potentiality of the site based on extensive literature reviews. These 18 elements reflect environmental, social/cultural and legal aspects that may influence the decision process to select the desired site. Secondly, using ArcGIS Model Builder, 18 analytical elements were made into thematic mapping which represent systematically organized graphic input to the model with automatic double check system and overlay analysis capability. Thirdly, to validate the effectiveness of the developed model, site location analysis was performed using the actual site, Buk-ku, Pohang.

In Korea, local government officials are in charge of buildings, and as such are supposed to review submitted documents related to the architectural administration to ensure that they comply with the legal standards. However, these officials generally put a greater emphasis on the preparation of the set of documents required for the administrative work than the content the documents contain. For this reason, many experts point out that the shortage of officials specialized in buildings and construction, as well as the lack of expertise among the building officials in the local governments, may result in repeated safety accidents during building construction. The purpose of this study is to propose the operational direction of a Regional Building Safety (RBS) center to secure the performance and safety of buildings by utilizing private resources. In this study, we carried out a pilot project to verify the effects of an RBS center and to derive the specific number of experts required. As a result, the technical matters were resolved in approximately 15% of the total cases of the document processing procedure, and the level of technical specialization among the officers has also been improved through the provision of guidance. The research findings support the validity and effects of the introduction of the RBS center. Finally, this study proposes (1) the types of RBS Centers that should be established, (2) the roles and business scope of the RBS Center, (3) the specific number of experts required, (4) the qualifications of the experts, and (5) the business regulations of the RBS Center.

Due to increasing legal and market demands for safety in the automotive design process, the design of integrated seat is important more and mote because it should satisfy the conflict between stronger and lower weight for safety and environmental demands. In this study for crash simulations, the numerical simulations have been carried out using the explicit finite element program LS-Dyna according to the FMVSS 210 standard for safety test of seat. Since crash simulations are very time-consuming and a series of simulations that does not lead to a better result is very costly, the optimization method must be both efficient and reliable. As a result of that, statistical approaches such as design of experiments and response surface model have been successfully implemented to reduce time-consuming LS-Dyna simulations and optimize the safety and environmental demands together with nonlinear optimization algorithm. Design of experiments is used lot exploring the design space of maximum displacement and total weight and for building response surface models in order to minimize the maximum displacement and total weight of integrated seat.
