This study focuses on the differences in general self-concept, academic self-concept, significant others self-concept and emotional-physical self-concept in relation to appearance management behavior. It goes on to show that appearance management behaviors such as styles in clothing, makeup, skin care, hair care, cosmetic surgery and body shaping, weight control management are strongly influenced by self-concept. Therefore, this study was carried out with the aim of providing basic understanding and information on the appearance management behavior of middle school students. It was also done in an effort to find ways of improving the self-concept of students through education as a part of the domestic science curriculum. The results obtained in this study are as follows: On average, the middle school students who took part in this study showed low self-concept and appearance management behavior which indicates a negative image of themselves. This suggests that efforts need to be made so that students can see themselves in a positive way and improve their self-concept through appearance management behavior. Middle school students with a positive self-concept try to present themselves by keeping their skin clean and their hair attractive. They express their self-esteem and personality through fashion and by keeping and maintaining their clothing, shoes and bags. They also tend to show a positive attitude towards their studies and are more likely to understand and get along with others. The students who showed positive attitudes towards their bodies and emotions have a higher interest in clothing and try to express the image that they want for themselves. They are also less likely to change their bodies unnaturally through cosmetic surgery and body shaping. Appropriate appearance management behavior can help middle school students see themselves in a more positive way.

This study is about what process and methodology could make UI designer be able to achieve the interface which considers user's mental model through implementing corporate line-up model, when people design an interface between product of multi-function printer and user. The most important concern of UI designers who are dealing with an interface between product and user is how they can make product system image match user's mental model so that users can utilize products without any confusion and discomfort. If concept model which designers bring up and mental model which users expect and recognize could be of one accord, then users can feel ease of use toward products. The understanding and observation for user behavior and use pattern is prerequisite to develop user-centered interface between product and user. However, UI designers do design interface from their own perspective and assumption in many business areas, and users do not react as designers assumed and intended in many cases or examples. This study is to find inappropriate system images against users' mental model on basic function of multi-function printer, and the relationship of system image and user's mental model is diagramed to build up a hypothesis. The hypothesis from this study is validated through evaluation of domestic and international users. In addition, two suggestions to improve usability problems revealed from user test are proposed. The optimal solution is designed based on the result of user evaluation and consideration of many user environments, and then it is implemented to line-up product. In conclusion, this study considers how UI designers can create system image which is close to user's mental model.

The metal matrix composites(MMC) are currently receiving a great deal of attention. These composites possess exellent mechanical and physical properties such as modulus, strength, wear resistance and thermal stability, which make them very attractive for use in automotive piston. In this study, $Al/{Al_2}{O_3}$(15%) composites are fabricated by the squeeze casting method. Mechanical properties such as tensile strength and ductility are performed at room and elevated temperature($250^{\circ}C$ and $350^{\circ}C$), respectively. Through thermomechanical analyser, thermal expansion coefficient of $Al/{Al_2}{O_3}$ composites are conducted for ranging from room temperature to ($400^{\circ}C$.And bending fatigue tests are also performed by the rotary bending machine at room temperature.The tensile strength and elastic modulus have been improved up to 38% and 35% by the addition of the reinforcements, respectively. Thermal expansion coefficients of MMCs which is located normal and parralel to the applied pressure are showed slightly different less than 10%. Fatigue strengh of the composite was improved by about 20% compared with that of unreinforced Al alloy. The results of this study will be used to understand the basic fracture behavior of MMCs and eventually to expand the applocation of MMCs as a machine parts undertaken various loadings.

The behavior of building industry metal sheeting under shear forces has been extensively studied and equations have been developed to predict its shear stiffness. Building design engineers can make use of these equations to design a metal deck form bracing system. Bridge metal deck forms differ from building industry forms by both shape and connection detail. These two factors have implications for using these equations to predict the shear stiffness of deck form systems used in the bridge industry. The conventional eccentric connection of bridge metal deck forms reduces their shear stiffness dramatically. However, recent studies have shown that a simple modification to the connection detail can significantly increase the shear stiffness of bridge metal deck form panels. To the best of the author's knowledge currently there is not a design aid that can be used by bridge engineers to estimate the stiffness of bridge metal deck forms. Therefore, bridge engineers rely on previous test results to predict the stiffness of bridge metal deck forms in bracing applications. In an effort to provide a design aid for bridge design engineers to rely on bridge metal deck forms as a bracing source during construction, cantilever shear frame test results of bridge metal deck forms with and without edge stiffened panels have been compared with the SDI Diaphragm Design Manual and ECCS Diaphragm Stressed Skin Design Manual stiffness expressions used for building industry deck forms. The bridge metal deck form systems utilized in the tests consisted of sheets with thicknesses of 0.75 mm to 1.90 mm, heights of 50 mm to 75 mm and lengths of up to 2.7 m; which are representative of bridge metal deck forms frequently employed in steel bridge constructions. The results indicate that expressions provided in these manuals to predict the shear stiffness of building metal deck form panels can be used to estimate the shear stiffness of bridge metal deck form bracing systems with certain limitations. The SDI Diaphragm Design Manual expressions result in reasonable estimates for sheet thicknesses of 0.75 mm, 0.91 mm, and 1.21 mm and underestimate the shear stiffness of 1.52 and 1.90 mm thick bridge metal deck forms. Whereas, the ECCS Diaphragm Stressed Skin Design Manual expressions significantly underestimate the shear stiffness of bridge metal deck form systems for above mentioned deck thicknesses.

This paper analyzed the degradation behaviors of silica nano epoxy composite based on the isoconversional method. The size of the silica nano particle was about 12 nm and the particles were mixed by three different weight ratios to make the degradation test samples. The thermogravimetric analyses were performed under six different temperature increase rates to measure the weight changes. Four different methods, Friedman, Flynn-Wall-Ozawa, Kissinger and DAEM (Distributed Activation Energy Method), were employed to calculate the activation energies depending on the conversion ratios, and their calculation results were compared. The results represented that the activation energy was increased when the silica nano particles were mixed up to 10%, indicating the definite contribution of the particles to the degradation behavior enhancements. However, the enhancement was not proportional to the particle mixture ratio by demonstrating the similar activation energies between 10% and 18% samples. The calculation results by the different methods were also compared and discussed.

The car-dependent traffic system based on highly advanced industrialization and economic growth causes various urban problems including traffic jams, energy consumption, air pollution, noise, car accidents and other issues. Particularly in urban areas, air pollution from motor vehicles is worse than pollution from past industrialization. In this study, therefore, the authors grasped car exhaust reduction effects by using microsimulation and those traffic policies that could make cars flow smoothly, reducing the air pollution in urban areas through analysis on profitability. As a result, the weekday-based car using system has been found most effective as it does not need investment cost. However, this system may be socially unacceptable, as it requires the government to change driver behavior. Therefore, the government needs to first reach a consensus with the citizens regarding this system. This system will also be effective with other alternatives. As a follow-up study, the authors will research citizens' perceived impacts of car exhaust on air pollution through a study on preference and grasp the possibility of applying these study results to real traffic policies.

The purpose of this study was to examine the consumers' purchasing behaviors of budget-priced cosmetics. Questionnaires used for this study were composed of 44 questions including 9 questions about budget-priced cosmetic purchasing behavior, 15 questions about satisfaction, 15 questions about repeat purchasing intention, 1 question about the reason of satisfaction or dissatisfaction, and four questions about demographic variables. Questionnaires were administrated to 317 people who were Daegu & Kyungpook region residents and had shopping experience on budget-priced cosmetics during 2 weeks from March 2005. Respondents' age was limited from 20 to 40. Data were analyzed by using correlation, crosstabulation analysis, and frequency analysis utilizing SPSS/WIN. The results were as follows. Consumers went to budget-priced cosmetics' shops 'for low price', 'for trial' and 'for curiosity'. The best purchased products among the budget-priced cosmetics were basic cosmetics, and the second purchased products were make-up cosmetics. 41.4% of the whole respondents answered that they spent 5,000~10,000won per one time visit, and 65% of those answered they visited once or twice per a year and once per two or three months. In this study a level of satisfaction for the entire products, consumers neither unsatisfied nor fully satisfied. For the question of the intention to repurchase for the budget-priced cosmetics, the respondents answered that they will not positively purchase again. A level of satisfaction and the intention to repurchase had positive correlations. The reason which consumers satisfied with the products was chiefly related to price and that which consumers unsatisfied the products was related to products themselves.
