This study aimed to analyze the preliminary data to increase the residents' satisfaction of mixed-generation house-sharing. For this purpose, we examined the recognition and demands of different generations and compared the differences. The participants were 50 elderly and 100 young people living in Seoul. The data were analyzed using SPSS statistics. The key findings are outlined below; 1. Most of the young people in our sample got to know about the house-sharing via various routes, but this option was not well known to the elderly. The interest in living in a house-sharing situation was higher among the young people than among the elderly. The reason why people were uninterested in house-sharing was their comfort in living alone. 2. Secure personal-space privacy and the choice of a housemate were regarded as the most important considerations in house-sharing by the young and the elderly, respectively. Young people anticipated a division of housework and the elderly were worried about communication with the younger generation. 3. Expected benefits tended to be higher in economic aspects for the young and in psychological aspects for the elderly. The elderly responded that they would be willing to share the kitchen and living room with the younger generation. Young people demanded necessary living facilities such as a laundry room and a community area with the elderly. The majority of the respondents from both generations said they would be able to solve problems through communication. In conclusion, public relations are needed to increase interest in house-sharing. The elderly and young should understand its purpose and treat each other as family members, not as house owners and tenants. There should be a manager who can coordinate the residents.

Mathematical justification is essential to assert with reason and to communicate. Students learn mathematical justification in 8th grade in Korea. Recently, However, many researchers point out that justification be taught from young age. Lots of studies say that students can deduct and justify mathematically from in the lower grades in elementary school. I conduct questionnaire to know awareness and steps of elementary school students and middle school students. In the case of 9th grades, the rate of students to deduct is highest compared with the other grades. The rease is why 9th grades are taught how to deductive justification. In spite of, however, the other grades are also high of rate to do simple deductive justification. I want to focus on the 6th and 5th grades. They are also high of rate to deduct. It means we don't need to just focus on inducing in elementary school. Most of student needs lots of various experience to mathematical justification.

In order to do morally right behavior that we cognitively know, prosocial moral motivation is necessary. Previous studies revealed emotion is important for prosocial moral motivation. This was supported by cognitive neuroscience studies using functional magnetic resonance imaging(fMRI) in which the activity of ventral striatum(VS) was observed when people made moral decision. VS was originally known as the core area of reward process but recently VS was found to respond also to social reward and even feeling of prosocial emotion itself. However it is not clear why VS was activated when people experience prosocial moral sentiments. The aims of this review article were to find situations in which people are prosocially and morally motivated and to understand more about the role of emotion as a moral motivator by examining evidence regarding the neural network, including VS, of prosocial moral motivation and moral decision-making.

To attain competitiveness in the severe competition of retailing, retailing firm like Aekyung department store composites multiplex entertainment shopping mall with other firms as key tenants like LG supermarket, Books Libro, and CGV. But in multiplex entertainment shopping mall customers who have experienced a service failure in key tenant's shops usually ask a compensation of service failure to the lessor like department store. Even though customers of multiplex entertainment shopping mall know that key tenants use different service strategy, personnel management system and operation system and so on, they do not rare of it. Why they do that? How can we explain this situation? This study explains customer's complaining behaviors in multiplex entertainment shopping mall using attribution theory and justice theory. The study presents a comprehensive model about the effects of the perceived attribution and fairness on customer satisfaction and suggests practical implications for retailing firms composing multiplex entertainment shopping mall.

World Wide Web(WWW) has a lot of useful charaters. Easiness of use, multi-media data supporting and interactive communication capability are typical reasons why people want to use WWW. But because WWW is based on Internet, it has some security problems which originate in plain format data transmission on physical transmission line. The unique solution fer this problems is data encryption. Since theoritically proved encryption algorithms ensure data confidentiality, a unauthorized user can not know what is transmitted on network. In this paper, we propose a cryptography system which uses public key system. In detail, our public key based web security mechanism is using PGP module. PGP is a e-mail security system implemented by Phil Zimmermann. The basic idea of our propose is data encryption and integrity checking for all data which is transmitted on Web. To implement these facilities, we. use netscape browser extension technology, plug-in. Through these technology, security mechanisms are added on netscape browser.

This study was done to identify experience of young adults street homeless aged 20-30s by knowing meaning and structure of empirical phenomena for procedure that how young adults became street homeless according to bio-psycho-social change. Five young adults street homeless were recruited who were on the air of SBS program, 'That why we want to know: young hope on the road-Young adults homeless are increased(Saturday July 26, 2008)', and from monthly magazine published by Homeless Center in Seoul. And phenomenological and heuristic Human Becoming Research Methodology of Parse was applied in this study. Although young adults street homeless made an opportunity for job, the working poor made him street homeless who suffer from social stigma and exclusion, but he struggled for self-support with social care. The quality of life for young adult street homeless depends on the social care under human rights with the bio-psycho-social aspects.

Sex does not mean simply the physical behaviors related to man and woman, rather the sexuality needed socializing process toward total personality. It is believed that religion or social norms on sex, limit talking about sex openly. But children have, their own sexual thinking and want to know why and how. This survey was conducted to find out the need in sex education of primary school students and their parents in Seoul area, comparing students'sexual knowledge, attitude, and behavior to their parents', in October 1989. Total 400 students and their parents who are attending two primary school in Seoul, were given the questionnaires, and 395 students' and 310 parents', respectively, were finally analyzed. The following results were obtained. 1. The mean of 11 questions In asking sexual knowledge of students was 6.18, and showed no difference between boys and girls. But the higher grade, the higher score. 2. The positive attitudes on marriage and sex roles were showed, but negative on physical changes with puberty, which was same to the parents' reaction. 3. Moro than three-forths of students wanted to take sex education class, and one-third of them believed that it should be conducted by school nurses. This was accorded with their parents. 4. The sexual knowledge degree and attitudes of parents went proportionately to their higher educational background. Protestants reacted more negatively to the given sexual terms. No significant difference was made among the age groups of them. As stated above. the degree of sexual knowledge and attitudes are movable accordingly to their children's sexual thinking and need. Therefore, it is strongly recommended that sex education In the primary schools should be conducted systematically involving parents, especially mothers. And it is suggested that school nurses undertake their responsibilities as the sex educators.

This paper aims at finding some lessons applicable to successful implementation of 'The 3D Printing R/D Project' through both examining the process of adopting overseas industrialized housing production technological knowhow by home builders during the 1970's~1980's period and thereafter until now the various efforts to adjust the technologies efficiently to the Korea's unique situation. Some meaningful lessons can be summarized as follows; I) Deep understanding of 3DP technological know-why along with its inheritance, II) Readjusting of R/D period and goals(cf. Global leader Winsun's 15 years experiment), III) Restructuring for more collaborative R/D B&E system among participating researchers IV) Fostering 3DP expert-engineers and technicians from the early stage, V) Clearing legal barriers in users' adopting 3DP methods necessary, VI) Development of appropriate building material besides concrete. Therefore, it is highly recommended that the above-mentioned 6 lessons positively accepted and applied to the Research Implementation Plan in due course, especially by KICT consortium and KAIA under the guidance of Ministry of Land, Infrastructure and Transport.

Bronchogenic cyst arises from anomalous budding of the primitive foregut during embryonic development and it represents a part of the spectrum of bronchopulmonary foregut malformations. Approximately two-thirds of the malformations are found within the mediastinum, and one-third are found in the lung parenchyma. The prevalence of bronchogenic cyst is unknown, presumably because most patients are asymptomatic. Incidentally detected bronchogenic cysts are usually removed at the time of diagnosis. We do not know how and why bronchogenic cysts grow. We recently experienced a case of rapidly growing mediastinal mass in a young adult, and this presented as a huge mass that had newly developed within one year. This mass was pathologically confirmed to be a bronchogenic cyst. We report on this case of a rapidly growing bronchogenic cyst, which is a rare characteristic of this type of cyst.

$Ly{\alpha}$ blobs are mysterious, giant (~100 kpc), glowing gas clouds in the distant universe. They occupy the dark matter halos that will evolve into the richest groups and clusters today. The blob's gas may be the proto-intracluster medium and their embedded galaxies are considered as the progenitors of massive cluster galaxies. Yet we do not know why $Ly{\alpha}$ blobs glow. There are evidences of kinematic measurements to exclude shocks and winds from AGN or starbursts as a power source, suggesting that photoionizing radiation or scattering of $Ly{\alpha}$ photons might be responsible. Polarization mapping can discriminate between these photo-ionization and scattering. Previous results of imaging polarimetry for $Ly{\alpha}$ nebulae are roughly consistent with scattering models. However the polarization morphologies in those of previous results are all different, motivating our polarimetric survey of $Ly{\alpha}$ nebulae for the statisticallymeaningful sample. As initial results of our survey, we present the total polarization map of the LABd05 which has the spatial offset between the peak of $Ly{\alpha}$ surface brightness and an obscured AGN. We detect the significant polarization in this target with the radially increasing polarization gradient, suggesting that scattering plays major role within this nebula. The polarization pattern is more aligned with the $Ly{\alpha}$ peak rather than the AGN (the potential energy source), indicating that the $Ly{\alpha}$ photons are originated from the region near the peak of $Ly{\alpha}$ intensity.
