This study is aimed to provide a guide for PC use space in apartment. To achieve this, a design about PC use space which was considered adequate location, area, form was suggested. As methods of the study, survey research method and case study. The survey was taken by five hundred-eighty-nine people who used PCs in apartment from May 2005 to July 2005 in Je-Ju province for an analysis of data. The results of the survey were showed PC use space situation and furnitures layout patterns. The case was classified by unit plans of size, and it showed design example of PC use space. In case of the 20s pyeong(about 3.30 square meters) type, PC use space was located in dead-space in the residence with minimum scale, because of 20s pyeong types are smaller than the other types. In case of the 30s pyeong type, PC use space which was divided with a partition panel was located in the livingroom expanding the room space to the balcony. In case of the 40s pyeong type, PC use space was located in the room of sons or daughters which was arranged with other furniture. The adequate area of PC use space is 1.4$^{\sim}$2.2 square meters, and it should take into account furniture size and human active sphere. And PC use space of form should consider traffic line, personal space and privacy. Besides it is required of ergonomic design in chair, table in its scale. And it is necessary development of systematic furniture for PC use space.
This study is to investigate Trademark Prior Use Defence of prior use party under Trademark Law of the People's Republic of China. Chinese Trademark Law was amended for the third time and this Law shall enter into force on 1 May 2014. This third amendment introduced Prior Use Defence Right of Trademark for the first time. Article 59(3) gives the right to the prior use party for the continuous use of such trademark under the condition that first, an identical or similar trademark has been used in connection with the same goods or similar goods by others before the registrant's application, second, such trademark should have a certain influence in certain market, and third, such aforesaid trademark should be used within the original scope continuously. Then the exclusive right holder of said registered trademark shall have no right to prohibit others from continuous use of such trademark. Korean companies should be aware that it is almost impossible to search prior use trademark before a dispute arises, since the prior use trademark has never been registered. The best way to control the prior use trademark is to superintend aforesaid trademark for the use within the original scope.
Purpose: Internet is one of the essential tools in South Korean adolescent life. Recently, researchers suggest that Internet use is positively associated with teens' mental health problems such as depression and suicide. Thus, this study explored a relationship between Internet use and suicide ideation among South Korean adolescents. Methods: Secondary data, the three-wave Korean Youth Panel Survey, were analyzed. First, in terms of the levels of Internet use and suicidal ideation, t-test was used for examining a gender difference, and Analysis of Variance were used for examining differences across three points in time(waves 2 - 4). Second, logistic analysis was performed to examine the significant association between Internet use and suicide ideation after controlling for the other factors' effects. In this analysis, Fixed Effect Regression Method(FERM) was incorporated as well. FERM was useful in adjusting for the effects of time-invariant factors even without measuring them. As a result, it was possible to obtain more accurate findings. Results: Adolescent depression was an important factor influencing the association between Internet use and suicide ideation. After controlling for the effect of depression, the relationship between Internet use and suicide ideation was no longer statistically significant. Conclusion: As a proxy to identify teens who are obsessed with suicide ideation, levels of Internet use do not seem useful. Instead, it is necessary to examine teens' access to websites related to suicide.

Use case diagram is used for defining inter-action between users and systems in object-oriented modeling. It is very important to defining users' requirements for efficient software development. In this paper, we propose a object-oriented modeling process using hierarchical use case analysis for designing class model. First, We define many use case diagrams by several hierarchical modeling level. And next, we can also design class model using the use case diagrams. Our proposed modeling process provides interaction between use case model and class model. That can make us to check the modeling process during the software development. Using the proposed object-oriented modeling we can develop software based on users' requirements. It is very useful for class modeling.

The purpose of this study is to grasp a concept for mixed-use tendency of educational facilities, its propellant circumstance in the nation and japan, to analyze a feature of a function, a flow planing of user and the complex form which appear from an instance of the mixed-use tendentious educational facilities and is to suggest a basic matter on the architectural planning for mixed-use tendency of the regional facilities and educational facilities. The results of the study can be summarized were as follow: 1) The step of mixed-use in nation is yet the early step and a extremely feeble to compared with the japan. 2) In a case of the mixed-use tendency facility, the nation is to appear for the necessity of a region but they know of a varied facility to be mixed-use tendency in japan. 3) Much to appear monolithic form in the side of complex form. 4) To appear multi-story in the side of facility-story. 5) It is much example of separating from main entrance, the flow of interior found of dividing into not to transit or transit by the function of facility. 6) To know for being tendency of common and division by the principal of user in facility instituting E V.
The purpose of this study is to examine the differences of use behavior and environmental perception of a park and to analyze the influence of environmental perception factors on park satisfaction among 7 parks in Suseong-gu, Daegu. The data from the 255 questionnaires of young adults (30-59) and old adults (more than 60) who use the park more than once a week were used for the analysis. In terms of park use behavior, young adults used the park for walking and jogging mainly on weekday evenings, while old adults used the park for walking and rest mainly during weekday daytimes. In addition, old adults used the park more times a week than young adults, and spent more time in the park. In the analysis of the environmental perception of the park, similar results were found in both age groups but overall, old adults were more satisfied with the park environment than the young adults. As a result of analyzing the influence of environmental perception factors, it was determined that park satisfaction in young adults has a significant influence on 'use amenity', 'use convenience', 'facility suitability', and 'landscape diversity' in this order. On the other hand, park satisfaction for old adults has an influence on 'use amenity', 'facility suitability', and 'use convenience' in this order. The findings of this study can be used as an effective basic data for future park planning considering age groups.
Purpose: The purpose of this study was to identify the relationship between intention to use advance directives and level of death anxiety in community-dwelling elders. Method: The participants were 200 older adults who were aged 60 or over and attended the community welfare centers. The level intention to use advance directive was measured by a questionnaire that was developed by the authors for the study. The measure by Kraus and Ellisond was administered to evaluate the level of death anxiety. Result: The average score for intention to use advance directives was $2.05{\pm}0.88$ and that of death anxiety was $6.2{\pm}2.28$. There were significant differences in the intention to use advance directives according to education levels and individual properties. Although there was no significant relationship between the intention to use advance directives and the level of death anxiety, they were negatively associated. Therefore, older adults who had lower death anxiety would tend to use advance directives. Conclusion: It would be necessary to screening the level of death anxiety to promote use of the advance directives. In addition, education programs for advance directives would be essential to consider about advance directives for their end-of-life especially for the community-dwelling elderly in Korea.

Objectives There has been a growing concern about the possible carcinogenic effects of the electromagnetic radiofrequency fields emitted from mobile phones. The purpose of this study was to investigate the association between mobile phone use and the development of gliomas in Korea. Methods Our study methods were based on the International Interphone study that aimed to evaluate possible adverse effects of mobile phone use. This study included 285 histologically-confirmed Korean patients 15 to 69 years of age, with gliomas diagnosed between 2002 and 2007 in 9 hospitals. The 285 individually matched controls were healthy individuals that had their medical check-up in the same hospitals. Unconditional logistic regression was used to calculate the adjusted odds ratios (aORs) and 95% confidence intervals (CIs) for use of mobile phones. Results For the entire group, no significant relationship was investigated between gliomas and regular use of mobile phones, types of mobile phones, lifetime years of use, monthly service fee, and the other exposure indices. Analyses restricted to self-respondents showed similar results. For ipsilateral users, whose the body side for usual mobile phone use match the location of glioma, the aORs (95% CIs) for lifetime years of use and cumulative hours of use were 1.25 (0.55 to 2.88) and 1.77 (0.32 to 1.84), respectively. However, the contralateral users showed slightly lower risk than ipsilateral users. Conclusions Our results do not support the hypothesis that the use of mobile phones increases the risk of glioma; however, we found a non-significant increase in risk among ipsilateral users. These findings suggest further evaluation for glioma risk among longterm mobile phone users.

The purpose of this study was to analyze the internet usage patterns among adolescents and to provide basic data for the development of internet addiction prevention program. The subjects of this study were 1169 students in middle and high school students in Seoul, Korea. Self-administered questionnaires were employed and data were analysed by SPSS 12.0. Major conclusions were as follows: 1. Most of the students were found to be the normal internet users. On the other hand, potential risk group was 8.2% and high risk group was 4.7%. Every students have had an experience of inter use. The 90.6% of the students' households had internet links. The percentage of students who were using internet more than 3 hours a day was 25.7%, and The most popular type of website was entertainment. 2. Male students showed greater percentages of potential risk and high risk group than female students. The students having parents in divorce, remarriage and separation were more likely to be in potential risk group than those having normal parents. The staying alone in home after school and small sleeping time were positively related to high level of internet addiction. 3. The characteristics of the students in potential risk and high risk group were longer duration of the internet use, internet use through the whole week, frequent internet use late at night, frequent use of pornographic site, main purpose of internet use for entertainment and shortage of rest during internet use. This study results had an limitation of generalizing to entire Korean adolescents because the sample of this study was middle and high school students living in Seoul. Future study was needed for the analysis of internet use behavior of the entire Korean adolescents, and for the identification of the accurate predictors for adolescents' internet addiction.
