모바일 디바이스의 급속한 보급으로 사용자들은 새로운 모바일 소프트웨어 대한 요구가 증가하고 있으며 소프트웨어 공급자(개발자)는 빠르고 적합한 소프트웨어를 제공할 수 있어야 한다. 그러나 모바일 플랫폼 구조에서는 수정된 모바일 앱을 사용자에게 제공하기 위해서 복잡한 프로세스를 거처야 하며 신속하고 즉각적인 업데이트를 제공할 수 없다. 이에 반해 모바일 웹은 다양한 수정 요구사항에 대해 사용자에게 즉각적인 변경을 제공할 수 있기 때문에 모바일 웹의 사용이 증가하고 있다. 따라서 본 논문에서는 모바일 웹 개발 및 유지보수의 생산성을 향상시키기 위한 동적 설정기법을 제안한다.

According to the relation of the attribution of residents, we analyzed the spatial characteristics of newly-built Hanok in Bukchon focused on a spatial area-ratio, the number of rooms, L/D/K configuration. The results are as follows: 1) Have increased the number of residents, the family members are also increased. In this study, the major formed case is 3 residents and two-generation family. 2) In the most cases, R area-ratio is the highest, next to L/D/K integrated area-ratio. While the examples that the L/D/K integrated area-ratio is lower than R area-ratio, or is also higher than R area-ratio are appeared. These examples can present that it has a tendency to secure the necessary room depending on the attribution of residents. 3) L/D/K is classified into four types of connection. And the characteristics depending on the number of rooms are as follows. L+DK is the most common type, next to LDK>LD+K>L+D+K. And L+DK is widely distributed in each sized area. And particularly, it is appeared mostly in 3R.

This study aims at finding the trend changes of spatial configuration in housing units of Korean apartments in the 2000s. Among the housing units in the apartments built by large construction companies, we have selected ones with small and regular sizes, $59m^2$ and $84m^2$ respectively, and investigated the number of bays, the location of wet zone and the spatial flexibility in the housing units selected for analysis. In conclusion, the number of bays in the housing unit has gradually increased, after allowing for the structural change of the balcony in the legal. It is estimated that the trend has came from the intent to increase the numbers of the externally exposed surfaces of the balcony, ensure a good view, lighting, ventilation and spatial flexibility. The location of wet zone, water-needed space such as a bathroom or a kitchen, has changed in the direction to facilitate the expansion and modification of space. Variable range of space has gradually expanded by using the balcony and wet zone as much as possible. In order to configure more effectively spaces in housing environments, the future study should be implemented to develop tools for realizing sustainable housing environment at the levels of not only the housing unit. but also the entire building, housing site, and city.

The configuration of Distribution Automatic System(BAS) is dual servers and raid 5(redundant arrays of inexpensive disks) clustering dual HDD. The DAS has the distributed object-oriented architecture using middleware software(BASEstar), so the number of client nodes has no limitation. Because the DAS is scalable, it can be configured using various application programs and be upgraded easily. The DAS has competitive to export because there are system development and accumulation of technology that coincide in International Standard, using common 05 and DB. This paper describes the structure of DAS hardware and software separately and proposes to improve program to share real time DB efficiently at each node.

The braking hose in the automotive hydraulic braking system exhibits the complicated anisotropic large deformation while its movable end is moving along the cyclic path according to the steering and bump/rebound motions of vehicle. The complicated large deformation may cause not only the interference with other adjacent automotive parts but also the durability problem resulting in the fatal microcraking. In this regard, the design of high-durable braking hose with the interference-free layout becomes a hot issue in the automotive industry. However, since it has been traditionally relied on the cost-/time-consuming trial and error experiments, the cost- and time-effective optimum design method that can replace the experiment is highly desirable. Meanwhile, the hose deformed configuration and fatigue life are different for different hose cyclic paths, so that their characteristic investigation becomes an important preliminary research subject. As a preliminary step for developing the optimum design methodology, we in this study investigate the hose deformed configuration and the fatigue life for four representative hose cyclic paths.

A SIL(Safety Integrity Level) assignment method is used for preventing failure action. The goal of safety system for processing automation is to reduce the human fatal risk. Even if we have developed the processing automation according to developing technology, we are also realized on increasing the human fatal risk cause of unexpected accidents. This study is directed the solution of decision for safety level for safety system and the best architecture for safety system in process automation.

Nursery is a very important space for the development and growth of children. Domestic national nurseries mostly have uniform space composition, and there is no significant difference from the general architecture. Therefore, this study focused on presuming the cause of uniformity in domestic nursery space configuration through analysing the competition guidelines. For this purpose, we reviewed the procedure of the competitions and collected 57 competition guidelines for the last 10 years. The competition guideline was divided into design guidelines and evaluation items, and each of them were analysed focused on the contents of the items and the changes over time. The derived results suggested the problems which seem to affect the uniformity of the domestic nursery in three aspects: design guidelines, evaluation items, and the current procedure of nursery competitions.

More and more special-shaped structural systems have been widely used in various industrial and civil buildings in order to satisfy the new structural system and the increasing demand for architectural beauty. With the popularity of the special-shaped structure system, its seismic performance and damage form have also attracted extensive attention. In the current research, an experimental analysis of six groups of (2/3 scale) T-shaped column joints was conducted to investigate the seismic performance of T-shaped column joints. Effects of the beam cross section, transverse stirrup ratio and axial compression ratio on bearing capacity and energy dissipation capacity of column joints were obtained. The crack pattern of T-shaped column joints under low cyclic load was presented and showed a reversed "K" mode. According to the crack configurations, a tensile-shear failure model to determine the shear bearing capacity and crack propagation mechanisms is developed.

This study is intended to suggest an improvement scheme of activating container multiplex cultural space through an analysis of container architecture characteristics and a survey of user satisfaction, focusing on container multiplex cultural space located in Seoul city. Hence, the elements of multiplex cultural space and the characteristics of container architecture were deduced and analyzed through precedent study and literature review relating to multiplex cultural space and container architecture, and then an analysis framework was established with items to measure the user satisfaction. Based on this, a questionnaire was created, and users were surveyed through on-site visit. The results of analyzing the container multiplex cultural space users' satisfaction are as follows. First, in order to increase user satisfaction, it is necessary to highlight visual element. Second, there is necessity for distinct space configuration, such as connection, stack and extension by utilizing the fixed specifications, the characteristics of container. Third, there is necessity for extended space where people feel a sense of openness. Fourth, it should be improved so that air is well circulated by installing glass, operable window, etc. In further research, it is thought necessary to make a study of commercial space and facilities inside university besides multiplex cultural space.
