The purpose of this research were to identify the differences in clothing behaviors and psychological characteristics ill relation to age and residence and to identify the relative effects of Korean female adolescent's psychological characteristics on the clothing behaviors. The instruments measuring 9 psychological characteristics-adolescent egocentrism, social and general self-efficacy, public and private self-consciousness, boredom susceptibility, optimal stimulation level, body attitudes-were adapted from previous studies. Clothing behavior measurements were developed based on the pilot study results or adapted from previous studies. The data. collected from 2284 nationwide sample of Korean female adolescents(early, middle, late) was analyzed by frequency, two-way ANOVA, and LISREL confirmatory factor analysis. Clothing behavior were factor analyzed and 6 factors were identified: dressing for others. conformity to peers, clothing interest, self-expression, psychological dependence and clothing exhibition. Effects of age were dominant in 6 out of 9 psychological characteristics and five clothing behavior factors except conformity to peers. Dominant main effect of residence was found oかy in boredom susceptibility. From the results of LISREL, adolescent egocentrism, public self-consciousness and sensation seeking tendency were found to be the most influential psychological characteristics of female adolescents'clothing behaviors.

As of November 1st 2010, 59% of overall residences in Korea are apartments with 8,185,000 households and when including the multi-unit houses, 71.0% of the overall residences are multifamily houses. The apartments have become the most universal form of residence in Korea and its' relative weight will continuously increase in the future. Meanwhile, Korea has turned into aging society in 2000 and will turn into the super-aged society by 2026 to display the world's fastest speed for aging. Majority of the elderly will spend their declining years in apartments. To understand the residence consciousness and its' properties for unit housing of the elderly residing in apartments, the present study obtained the following results through surveying the 541 nationwide samples. First, the elderly most prefer the mid and high levels(6-9th floors, or 10-15th floors) of apartments. Second, the elderly couples most prefer areas of $85m^2$ while single elderly most prefer $60m^2$. Third, the elderly feel the most inconveniences in bathrooms and showers. Fourth, safety accidents in dwelling of the elderly have no significant correlation with age, gender or their possessed diseases. Fifth, the elderly displayed high satisfaction for their bedrooms. Sixth, there were less tendencies for elderly to feel lack of storage spaces or conduct remodeling. As a result of the analysis, all apartment houses of Korea must support the physical aging of residents and prevent safety accidents in houses to enable Korean aging in place.

This study investigated the differences in college students' attitudes towards, and knowledge of contraceptives. Gender, age group and place of residence were examined to identify variables related to contraceptive use. A total of 388 responses were obtained from college students. The results are as follows: Firstly, significant differences were found in degree of contraceptive knowledge between genders, age groups, and residence types. There was also a significant interaction effect between gender and age. Secondly, there were significant differences of attitudes towards contraception in gender and age and there was also significant interaction effect between residence type and age. Thirdly, college students' contraceptive use could be successfully predicted by gender and attitude towards contraception. Male students who had positive attitudes towards contraception were more likely to use contraceptives. This suggests attitudes towards contraception should be considered when developing contraceptive programs.

In the time of the rule of Japanese imperialism, Japanese style official residence played major role at the implantation of modern dwellings into Korea and its influences on Korean modern dwellings are distinguishable. This study focuses on the Japanese style official residence implanted into Korea before 1910. Before 1910 Japanese civilians in Korea builded just a traditional Japanese dwellings at the Japanese settlement in the ports opened. But Japanese engineers engaged in governmental organization of construction in the Old-Korean Empire builded a central corridor type Japanese dwellings as official residence. The central corridor type Japanese dwelling was an urban dwelling compromised between Japanese style and western style and distinguished by an outer-court type plan, Japanese entrance hall, central corridor and western style reception room. It is certified that the central corridor type Japanese dwelling was implanted into Korea before 1910 and this was the first time an urban dwelling to be implanted and spread through the whole Korea. The central corridor type Japanese dwelling implanted into Korea took in On-Dol and transformed to Korea-Japanese eclectic style. The central corridor type Japanese dwellings implanted into Korea in the time of the rule of Japanese imperialism makes function as a precedent of a modern urban dwelling to Korean and makes Korean dwellings transform from the rural inner court type into the urban outer court type.

전산유체해석 기법을 이용하여, 테일러 반응기 내 유동특성과 입자의 체류시간에 대하여 연구하였다. 테일러 반응기는 반응기의 작동조건에 따라 내부 유동특성이 달라지므로, 입구주입속도와 반응기 회전속도 변화에 따른 테일러 반응기 내부의 유동특성 변화를 살펴보았다. 또한 테일러 와류(TVF)영역에서 리튬이온전지의 양극물질인 NMC입자의 반응기 내 체류시간을 측정하였다. 입구에서의 복잡한 화학반응은 고려하지 않았고 테일러 유동의 영향만 고찰하였다. 해석결과 반응기의 회전속도가 높고 반응물의 주입속도가 낮을수록 입자의 체류시간이 길어지는 것을 확인하였다.

We analyzed the non-Newtonian and non-isothermal flow in the melt conveying zone in co-rotating and counter-rotating screw extruder system with the commercial code, STAR-CD, and compared the mixing performance with respect to screw speed and rotating direction. The viscosity of fluid was described by power-law model. The dynamics of mixing was studied numerically by tracking the motion of particles in a twin screw extruder system. The extent of mixing was characterized in terms of the residence time distribution and average strain. The results showed that high screw speed decreases the residence time but increases the shear rate. Therefore higher screw speed increases the strain and has better mixing performance. Counter-rotating screw extruder system and co-rotating screw extruder has the similar shear rate with the same screw speed in spite of different rotating direction. However, the counter-rotating screw has good mixing performance, which is resulted from longer residence time than that of co-rotating screw extruder.

Recently housing demands are going to be diversified, and many suggestions are driven for the housing consumer's right of choice and expectation for welfare services. These require the policy change from the clear division between houses and facilities toward more market-oriented concept capable of mixed-use development of houses with facilities. The research explores the possibilities to provide various types of mixed-use developments of houses and facilities in the level of architectural design and political implication. Major case studies focus on the elderly welfare housing with serviced residence with the comparison of similar cases in Japan. The policy implications are, first, expanding the production of elderly housing with more elderly care services, second, challenging time-sharing residence composed of serviced residence and small dwelling units, third, activating the production of small scale housing development with small public facilities. The simulation shows the merits and demerits of this concepts and the efficacy of the policy implications.

We analyzed the non-Newtonian and non-isothermal flow with Carreau-Yasuda viscosity model in co-rotating and counter-rotating twin screw extruder systems. The mixing performances with respect to the screw speed, the screw pitch, and the rotating direction have been investigated. The dynamics of mixing was studied numerically by tracking the motions of particles. The extent of mixing was characterized in terms of the deformation rate, the residence time distribution, and the average strain. The results showed that the high screw speed decreases the residence time but increases the deformation rate. Small screw pitch increases the residence time. It is concluded that the high screw speed increases the dispersive mixing performance, while the small screw pitch increases the distributive mixing performance. Co-rotating screw extruder has the better conveying performance and the distributive mixing performance than counter-rotating screw extruder with the same screw speed and pitch. Co-rotating screw extruder developed faster transport velocity and it is advantageous the flow characteristics to the mixing that transfers polymer melt from one barrel to the other barrel.
