It is very necessary and important that color image language is given to each coloring to highten efficiency on applying color scheme. For that in this research, literature cited and survey are carried out to select languages on the Korean's color-image connected with color scheme at the same time, and I did my best to objectify the subjective color image through verifying related experts. As the result of research, I classified the color image into 14 categories; A. energy or dinamic, B. harmony, C. order, D. style and fashion, E. mystery, F. Practically, G. dignity, H, gorgeousness, I. the sense of sight, touch, taste, hearing, J, complexity, K. sexuality and growth, L. standard, M. static and lyricism, N, simplicity to promote user's usefulness. For the user's convenience on color plan, the work to propose odor scheme concided with the selected color-image languages is deferred till the follow-up research.

Sheathing work used for excavation in a crowded downtown is generally a temporary strut method using H-piles and sheathing wall includes lagging, CIP, SCW or slurry wall. A temporary strut serving the support for sheathing wall acts to resist the earth pressure, but it shall be removed when installing the underground structure members. A traditional temporary strut might cause the stress imbalance of the sheathing wall when it is demolished, resulting in time extension and the risk of collapse. A traditional temporary strut method thus needs to be improved for schedule and cost reduction, risk mitigation and for preparation for potential civic complaint. A permanent strut method doesn't require installing and demolishing the temporary structure that will lead to reducing the time and cost and the structural risk during the demolition process. And given the girder, the part of the underground structure, serves the role of strut, it can secure the wider interval compared to the traditional method, which enables to secure the wider space for the convenience of excavation as well as enhance the constructability and efficient site management. The thesis was intended to study the composite girder designed to use the strut as permanent structure so as to reduce the excavation and floor height.

This paper presents the application of a robot which aims at grinding automatically welding-bead remained in the removal job of working pieces for shipbuilding. In specific, the investigation on this application is composed of two parts; one topic is on the development of a robot platform vertically movable on a steel plate of hull, while the other topic is of the development of a grinding tool mechanism in order to remove welding-beads by using a diamond wheel installed on a servo cylinder (which can result in high working pressure on the grinding wheel). Besides, the development of a vision system for tracking welding-beads as well as recognizing welding surfaces is added for the convenience of this robot application to the removal of welding-beads remained in the working pieces for shipbuilding.

When test tubes for PCM with melting point lower than a room temperature are installed vertically as the T-history method proposes, there exists a temperature distribution in the longitudinal direction by natural convection, which lowers the precision of measured heat-of-fusion. The purpose of the present work is to improve the precision by arranging the test tubes horizontally, while maintaining the simplicity and convenience. Assuming that the amount of heat transfer is very small through the vapor space formed in the upper part of the tubes by volumetric change, the obtained value by the T-history method using the latent heat period bounded by two inflection points is in good agreement with that of the literature. Also, the scattering of measured values by the proposed method decreases markedly compared to that of vertical positioning.

D/In modern production industries, computer aided systems have been improving the efficiency and convenience of the various stages of work. However. as the complexity of computerized production systems increases, various techniques are still necessary. The problem we addressed occurs in computer systems that automatically make manufacturing process plans in the metal grating manufacturing industry. In the grating layout design, the key to saving the manufacturing cost is to find a design with the minimal number of cutting operations. The proposed genetic algorithm explores the feasible alternatives within the space until an optimal solution is obtained.

This study is to examine the satisfaction of protective clothing for riot policewomen. The protective clothing that riot policewomen currently wear are not suitable for them because they are structurally designed for men. A survey was conducted about satisfaction of protective clothing for 190 riot policewomen who work in Seoul and Gyeonggi province. This study focused on functionality and comfort of the protective clothing. It examined overall condition of protective clothing and policewomen's satisfaction in terms of safety, activity, fitness, comfort, convenience and design. The first three aspects were examine to measure its functionality and the last three to measure its comfort. Most results show under 3 out of 5 point in terms of functions and comfort level. In conclusion, it is strongly recommended that new design which fits better to women according to their body structures and sizes as well as new fabric materials that permeability better are needed.

Purpose: The purpose of this study was to compare musculoskeletal pain, menopausal symptoms and depression by women's menopausal stage. Method: With a survey design, a convenience sample of 203 women between age of 40 to 64 was recruited through a community. Data were collected via a structured study questionnaire from May to July, 2008. Measures included with symptom severity list for menopausal symptoms, Aches and Pains scale, and Beck's Depression Inventory. Results: Thirty-seven percent of women belong to early peri-menopausal stage, 31% to late peri-menopausal stage, and 32% to postmenopausal stage. By group comparison, late peri-menopausal and post menopausal women reported higher scores of depression than early peri-menopausal women. Postmenopausal women had greater scores in two pain subscales (bodily pain and pain that interferes with normal work) and two menopausal symptoms subscales (sleep pattern and sexual behaviors) than early peri-menopausal women. There were moderate levels of positive relationships among study variables at each menopausal stage. Conclusion: Postmenopausal women seem to have greater musculoskeletal pain and menopausal symptoms, and have depression more than did early peri-menopausal women. Tailored nursing strategies are required to reduce these kinds of common symptoms for women with menopausal transition to improve their physical and psychological wellbeing.

As China, the world's work shop was transformed into consumption market intermediary products and expensive consumer goods are more in highly demand recently. These will tend to diffuse especially to the west coastal cities of China. The economic growth of China needs to develop hub port facilities more and more in these days. We don't need to explain value of hub port in international trade. Furthermore If we are to retain access convenience of merchant vessel we really must maintain hub ports in Korea. This paper aims to vitalize Pyeongtaek port in times of the Pan Yellow Sea in readiness for an increase of trade between Korean, China, and Japan absorbing economic effects. The Rise of China leads to increase of trade of Korea that make necessary to develop a big and wide port to Pan Yellow Sea times. There is a lot of competition to be a hub port to become a center of international trade in the Pan Yellow Sea market. We need to improve the surrounding environment or facilities and industry clusters flexibly of Pyeongtaek port. It will guide to cost cutting and to raise business efficiency. Ultimately Pyeongtaek port should maintain and make advance its competitiveness especially in the Pan Yellow Sea times.

The study is insufficient on process planning of the elliptical deep drawing product. Thus, in this present study, the expert system for elliptical deep drawing products was constructed by using process sequence design. The expert system was developed to be based on the general concept of each entity. The system was developed in this work consists of sixth modules. The first one is a shape recognition module to recognize non-axisymmetric products and to generate Entity_list. The second one is three dimensional (3-D) modeling module to calculate the surface area for non-axisymmetric products. The third one is a blank design module to create suggested blanks of three shapes with the identical surface area. The fourth one is shape design module based on the production rules that play the most important role in an expert system for manufacturing. The production rules are generated and upgraded by inter- viewing field engineers, plastic theory and experiments. The fifth and sixth ones are a graphic module to visualize results of the expert system and a post module to rise user's convenience, respectively. According to constructed the expert system for process sequence design, it was possible to reduce the lead time.
