The purpose of this study is to examine the preference for living with adult children of the baby-boomer generation and the elderly based on independent variables such as demographic characteristics, the values of their children and the consciousness for supporting their parents. The National Survey of Korean Families was done by the Ministry of Equality and Family in 2010. Respondents were 664 baby boomers and 628 elderly, and the results are as follows. First, the baby boomers rely heavily on their spouse, whereas the elderly rely heavily on their children. While both groups desire to live with their spouse in their later years, and the elderly rely the most on their children, they are reluctant to live together. This result shows that the elderly have high expectations for financial and emotional support from their children, but in reality, the elderly have lower expectations for living together and they prefer to live alone or with their spouse. Second, the boomers, who for the most part live in big cities, have comparatively high average monthly income and jobs and own a house, consider filial obligation as their own responsibility and yet tend to live independently. The boomers, who have a relatively high education level, consider living with aged parents as the children's obligation and consider their children as the most reliable people in their lives, and thus have high expectations to live together with their children. Third, the elderly, with a spouse, who consider having raised children to be their happiness, while considering providing financial support for the aging parents to be the children's responsibility, at the same time accept that the obligation of support lies on themselves, the government or the society, and thus have lower expectations of living with their children in later years. The elderly, now living with their family, with generous financial plans for their aging years and considering the children's success as their own success, have higher expectations of living together with their children.

Purpose: This study was executed to investigate the route of the sexual knowledge acquisition and the sexual problem behavior of primary school students in a region. Method: The subjects of this research who were primary school 5, 6 grade students of 990 people were chosen at random in big cities, small towns and rural areas in Jeonbuk province. Result: The route of the sexual knowledge acquisition was through taking lesson & teacher in the school(40.6%), the peer group or senior member(26.1%), internet(15.3%), parents(10.0%), and multimedia(8.0%). The domain of the sexual problem behavior showed sexual impulse 3.8%, sexual violence 3.7%, masturbation 2.7%, voyeur 1.8%, prostitution 0.8%, transvestism 0.5%, exhibitionism 0.1%. The sexual problem behavior experienced by 5.0% or more of the subjects showed the experience of another person's compulsory touching on their body, the embrace desire and the kiss desire with opposite sexual friend. And the biggest sexual problem behavior of the subjects was sexual violence and sexual impulse to opposite sexual friend. The experience rate of the 6 grade was higher than that of the 5 grade (p<.05) and the male students' experience rate of another person's compulsory touching on their body showed higher than that of the female students(p<.05). Conclusion: The author through these findings suggests that systematic programs and curriculum should be developed for sexual problem behavior prevention.

The purposes of this study were to provide information on the prevalence and change of Korean adolescent alcohol use and to identify related factors to adolescent alcohol use. This study collected data from a total of 4,373 adolescents nationally. Followings are the major findings of this study. First, 75.7 percent of respondents reported that they tried alcohol in their life time. More male respondents tried alcohol in their lifetime than female respondents, but there was no big difference. Findings on alcohol consumption by grade showed that as adolescents get older, they are more likely to try alcohol. Second, this study also found that whereas the drinking rates of male adolescents and higher graders were steady, the rates of female adolescents and lower graders were increased since 1997. Third, this study compared its findings with adolescent alcohol use in the United States. Little differences existed in measures of adolescent alcohol use in the two countries, but the differences in the rates of the past-month alcohol use and heavy drinking was greater in Korean adolescents than in American adolescents. Finally, this study found that peer related factors such as friend's alcohol use was the strongest factor related to respondents' alcohol use. Family-related factors and respondents' levels of psychosocial resources (cognitive control, coping skills, social support) were also significantly related to their alcohol use. This study suggest that future studies consider cultural aspects and regional differences in order to understand adolescent alcohol use in more depth.

This study was conducted to examine arthritis patients' knowledge level and its related factors. Data were collected from 100 people who suffered from arthritis in Seoul, Busan, Daegu, Daejun, Junjoo, and Pohang from June 1, 2000 to August 31, 2000. The results of this study are summarized as follows. 1. 61.0％ of the subjects was female. The incidence rate of arthritis was higher in the higher age group, lower educated group, and thinner group. In the case of male, the incidence rate was higher in the groups of single, residents in big cities, and technicians. In the case of female, it was higher in the groups of the married, residents in towns or villages, and housewives. 2. Among the sources of obtaining the knowledge related to arthritis, 38.0％ of the respondents obtained the knowledge from physicians and 24.1 ％ got it from TV or Radio. 14.6％ of them obtained it from family members, neighbors, and friends and 14.3％ got it from newspapers, magazines, and pamphlets. Only 5.8％ of them obtained the knowledge from pharmacists. The sources showed significant difference in the variables of age, occupation, marital status, religion, place of residence, and education level. 3. 47.2％ of them thought that education related to arthritis was needed without fail, while 12.5％ thought that it was not necessary. In the question related to concern about arthritis, ‘no concern’ was 31.2％, while ‘concern’ was 7.8％ and ‘a little concern’ was 45.1 ％. 4. The knowledge level of arthritis was 7.35 ± 1.51 points on the basis of 11 points. It showed significant difference in the variables of age, occupation, education level, and economic status. 5. The knowledge was influenced by the variables of economic status, necessity of publicity, treatment period, occupation, education level, and age. The arthritis patients did not have enough knowledge of arthritis because the education was not provided well for them. Therefore, related professionals and organizations must develop education program of arthritis in order to educate them.

When lighting has installed indoor, we control lighting using human-detecting sensors for people who pass at night and places that are lack of quantity of light. However, malfunction can be caused by positions of inappropriate sensors, and in the case of passages of big buildings, it is a problem that even after a person pass, light apparatuses are turned on for a long time. In this paper, we propose lighting control system based on location positioning for energy saving that control lighting in accordance with passers's position through indoor location positioning. This system use the fingerprinting technology that is one of the location positioning technologies and RSSI data that is collected by a smart device. Using those, it can turn on only lightings that are included in the positioned location and reduce unnecessary power consumption. As a result of experiment, on condition that four people were existing and illumination was 308 lux, we assured reduction effect of 49 Wh.

Nowadays, reduction of energy use in buildings is a big issue, especially in public buildings like schools. The building structure is very simple in that, the room size, schedule and user number is similar across different schools. There are many policies which are suitable for this kind of buildings. Investigation of energy consumption pattern in primary school, middle school and high school in different cities of Korea has been done in this paper using statistical data from national organization and the data from IBM and Gyeonggi Provincial Office of Education, aimed at providing the basic data for the development of energy efficiency improvement policies of educational facilities. The study was divided according to climate, energy source type and public or private school, as different cities have different climates and accordingly different amount of energy sources are used. It was observed that, the average energy consumption in primary school is $36.9kWh/m^2$, in middle school is $20.5kWh/m^2$ and in high school $27.4kWh/m^2$. As further analysis, monthly energy consumption pattern has been analyzed for one city.

This paper describes high speed and low power design techniques for an 8-bit 500MSamples/s CMOS 2-step ADC. Instead of the conventional closed-loop architecture, the newly proposed ADC adopts open-loop architecture and uses a reset-switch to reduce loading time in an environment of big parasitic-capacitances of mux-array. An analog-latch is also used to reduce power consumption. Simulation result shows that the ADC has the SNDR of 46.91㏈ with a input frequency of 103MHz at 500Msample/s and consumes 203㎽ with a 1.8V single power supply. The chip is designed with a 0.18mm 1-poly 6-metal CMOS technology and occupies active area of 760${\mu}{\textrm}{m}$*800${\mu}{\textrm}{m}$.

In this study, the domestic supply & demand of the raw materials of 35 rare metals was analyzed categorized as four types - ores, metals, compounds and scraps. Foreign trade volumes of the raw materials of rare metals have been steadily increased, furthermore, recently trade growth rate highly exceeds GDP. The raw materials of rare metals - silicon, nickel, molybdenum, manganese, etc. - for steel industry were the most big part of the raw materials of rare metals trade, while the raw materials of rare metals for electronics industry were imported relatively small volumes less than $100 million. However systematic supply & demand management on the raw materials of rare metals for electronics industry is needed since recently growth rate per year has been remarkably high over 20%. Import volumes were about three times bigger than export scale, and most of the raw materials of rare metals were traded as a metal form.

Since Hadoop which is the Big-data processing platform was announced, SQL-on-Hadoop is the spotlight as the technique to analyze data using SQL on Hadoop. Tajo created by Korean programmers has recently been promoted to Top-Level-Project status by the Apache in April and has been paid attention all around world. Despite a sensible change caused by Hadoop's appearance in DW market, researches of those performance is insufficient. Thus, this study has been conducted to help choose a DW solution based on SQL-on-Hadoop as progressing the test on comparison analysis of RDBMS and Tajo. It has shown that Tajo based on Hadoop is more superior than RDBMS if it is used with accurate strategy. In addition, open-source project Tajo is expected not only to achieve improvements in technique due to active participation of many developers but also to be in charge of an important role of DW in the filed of data analysis.
