This study examined and analyzed uses, transformations, changes of plane and arrangement, and changes of space structure of housing components with traditional folk houses located at Kyideok village, Hanrim-eup, Jeju, and the results of the study can be summarized as follows. First, the exposure of arrangement of folk houses at Kyideok village, Jeju was evenly distributed to the east, the southeast, the northeast and the west in order and it was little different from the use of sunshine conditions by placing the main room on the south in traditional houses of land areas. Second, the space structure of inner room before transformation was divided into seven types. 3-room type was classified into "Sangbang-centered three-room type" and "nanggan-centered three-room type", 4-room type into "four-room type with inner access to warehouse", "four-room type with outer access to warehouse", "kitchen-divided four-room type", "four-room type with two kitchens", "four- room type with nanggan at the right back". Third, according to types of change in arrangement type, the first is new annex addition to existing inner room, the second is the removal of existing annexes including outer room, the third is the extension of inner room size without new construction of annex, the fourth is new construction of annex with new plane form after removal of existing annex, the fifth is no change in arrangement of inner room, outer room, stable, warehouse, etc. Fourth, transformation of space components led to changes of space structure as well as those of plane form. Changes of space structure were divided into reduction type of circulation to specific factors, negligence type without using increased space factor, and addition type having various circulations through the increase of convenience space.

This paper examines the traditional house building components through Wenzhou Longwan district traditional residential architectural components exhibition. We found that the exhibition of architectural components of residential buildings has its own characteristics, and the collection, cleaning and organization of the components require a lot of manpower and material resources. This exhibition is based on social hotspots, and the exhibition was curated with flexible use of exhibition halls and content arrangement, allowing the audience to enter into "immersive" nostalgic memories through the experience of being present. In the wave of urban construction and development, the preservation of traditional residential buildings and their components is to inherit the local architectural culture and show the local natural and humanistic spirit.

Some classical plots like scatterplot matrices and parallel coordinates are valuable tools for data visualization. These tools are extensively used in the modern data mining softwares to explore the inherent data structure, and hence to visually classify or cluster the database into appropriate groups. However, the interpretation of these plots are very sensitive to the arrangement of variables. In this work, we introduce two methods to arrange the variables for data visualization. First method is based on the work of Wegman (1999), and this is to arrange the variables using minimum distance among all the pairwise permutation of the variables. Second method is using the idea of principal components. We Investigate the effectiveness of these methods with parallel coordinates using real data sets, and show that each of the two proposed methods has its own strength from different aspects respectively.

Partnering concept has been mentioned as an innovative arrangement that helps to reduce many of the disadvantages of the traditional arrangement. Partnering in construction has been widely applied in Vietnam from late 1990s. The application of the new has arrangement spread thanks to anecdotal proofs. This concept is quite new to Vietnamese practitioners. It is necessary to conduct study as a lesson-learn of the industry to encourage the partnering implementation. This paper attempts to develop a model, using discriminant analysis, which classifies the partnering in construction projects into success levels. Dedication, teamwork, sufficiency, and balance are the four significant components in discriminant model. The proposed model is helpful to practitioners in developing, adjusting and improving their strategy for partnering implementation.

The characteristics of flow and heat transfer in the heat exchanger of heat pipes with fins have been studied numerically for cooling enhancement of electronic components of KTX (Korea Train eXpress). Numerical analysis and methodology have been conformed by comparing the experimental results for inlined array of heat pipes. The staggered arrangement of heat pipes has been proposed in order to achieve heat transfer enhancement. As results, the geometry change to the staggered array is conformed to increase the heat transfer of the system accompanied by an increase of pressure drop. The current results of friction factor and Colburn j factor are presented in terms of Reynolds number and staggered distance, and are expected to use for design and manufacture of such a system.

The process of Lay-out design and assembly for liquid rocket engine was presented and the Lay-out design for main components of liquid Rocket engine system was studied. Vertical direction is recommended in the case of turbopump's arrangement. If the length of pipe between gas-generator with turbopump's turbine is shorter, gas-generator is stable. The arrangements of main valves are recommended as near disposition to combustion chamber, because shut-down process time is shorter. Interference with launch vehicle and structural strength considering gimbal actuator's force and control performance is considered in the case of gimbal actuator's supporter design.

Development of a long-range artillery intercept system to counter the threat of enemy long-range artillery is in progress. This intercept system is a complex combination of several components. In addition, the ability to engage simultaneously is emphasized due to the characteristic of having to respond to numerous enemy bullets. In this study, the performance according to the arrangement of the detection asset and missile launchers, which are key components of the system, is analyzed. A simulation experiment was performed assuming the enemy attack at various azimuth and launch angles. As a result of the analysis, the radar seems to provide sufficient detection capability in any situation, but in the case of the launcher, the effect of the enemy's launch angle can be critical. It is recommended to place both radar and launchers behind the protection target.

Unsatisfactory urban walking environment stresses urban residents, and may cause mental illness and chronic diseases by reducing walking activities. Therefore, establishing a high-quality walking environment that can promote walking activities in urban residents has emerged as an important issue. The walking environment consists of various components, such as trees, stairs, streetlights, benches, signs, fences, and facilities, and it is essential to understand which components and their settings act as satisfiers or dissatisfiers for pedestrians, to create a better quality walking environment. Therefore, this study investigated pedestrian satisfaction and dissatisfaction as a function of various environmental components through a survey using walking environment images. The results revealed that most of the walking environment components except the braille block and treezone exhibited significant correlations with pedestrian satisfaction. Particularly, safety-related component (e.g., adjacent roads, parked cars, traffic cushions, and car separation), and landscape-related components (e.g., trees and green), as well as the material settings of landscape facilities (e.g., wooden fences, benches, stairs, and walkway surfaces) correlated with pedestrian satisfaction. The results of this study can contribute to the extraction of useful features to evaluate pedestrian satisfaction as a function of the walking environment. The research outcome is expected to assist in the effective arrangement of walking environment components and their settings, which will ultimately contribute to significantly satisfactory walking environment and encourage walking activities.

This paper describes qualities of a library classification system that are commonly discussed in the LIS tradition and literature, and explains such a system’s three main functions, namely knowledge mapping, information retrieval, and shelf arrangement. In this vein, the paper states the functional requirements of bibliographic classifications, which broadly are subject collocation and facilitation of browsing the collection. It explains with details the components of a library classification system and their functions. The major components are schedules, notations, and index. It also states their distinguished features, such as generalia class, form divisions, book numbers, and devices for number synthesis which are not required in a knowledge classification. It illustrates with examples from the WebDewey good examples of added features of an online library classification system. It emphasizes that institutional backup and a revision machinery are essential for a classification to survive and remain relevant in the print and e-environment.
