The purpose of this study is to analyze the key factors affecting satisfaction of the visually impaired SNS users so that they may use SNS more effectively in the future. This study has used three factors such as the information factor, the relationship factor and the speed factor and the usability as independent variables. The social presence factor was used as a parameter and the SNS user satisfaction as a dependent variable. For the research, 195 visually impaired SNS users have participated in this survey. The major findings of this study are that the relationship factor has strong effects on the self-identification factor, the social presence factor and the SNS usage satisfaction among the factors affecting the visually impaired users to be satisfied with SNS. On the other hand, the information factor and usage factor have no effects on the self-identification factor and the social presence factor. However, they have effects on the SNS usage satisfaction. Additionally, the self-identification factor has no effect on the SNS usage satisfaction, but the social presence factor has effect. Based on the above study results, this paper proposed for the government to enhance the educational program on the use of SNS for the visually impaired and to increase its financial and political support on this subject. Additionally, technical supports on SNS service accessibility and usage by the government are vital for the visually impaired. Academically, this study provides a concrete groundwork for the research on the use of SNS by the visually impaired by providing a solid research direction for further study on this subject. Socially, this study helps the visually impaired use SNS more effectively by increasing the general public awareness of the importance of SNS usages by the visually impaired so that the information gap of the society may be diminished in the future.

The importance of the health care for the miners not only concerns the productivity of the enterprises but also as a fundamental human right, it has to be secured and protected by the society and the government. The Korean coal miners began to find their works at overseas since 1963 when the Korean government selected and dispatched its miners to West Germany. As years go by, the demand and the supply of the coal miners, the program of the coal miners health care became the important tasks to be solved and the further studies and research were necessary to support these tasks achievement. The writers made a statistical analysis on health status of the 1,559 Korean applicants applying for the coal miners in West Germany during the year of 1972 and 1973 by the using of the data of physical examination which were directed by the Korea Overseas Development Cooperation. The standard of physical examination which was applied for coal miners applying the jobs in West Germany was authorized by the Government Office of Labor in 1967. The results are as following; 1. The applicants were from the various provinces throughout Korea; Gang Weon 50.2%, Jeon-Nam 16.8%, Chung-Nam 13.7%, Gyeong-Nam 10.5%, City of Seoul 5.4%, and others 3.7%. 2. The ages of the applicants were from 20 to 44. The age group of 25-29(36.3%) and of 30-34(55.2%) together occupied the 91.5 per cent of the total applicants. 3. Among the 1,559 applicants 52.1 per cent passed the physical examinations. The tendency were shown that as the age increased, the passing rate decreased, and the married applicnts had lower passing rates compared to the unmarried applicants. 4. The height of the applicants averaged $168.4{\pm}4.74(cm)$ and the weight averaged $61.3{\pm}5.65(kg)$. 5. The average vision of the left eye of the applicants was $0.92{\pm}0.23$ and the right eye was $0.91{\pm}0.30$. 6. The mean value of the systolic blood pressure of the applicants was $145{\pm}13(mmHg)$ and the diastolic blood pressure was $85{\pm}8(mmHg)$. 7. Fifteen hundred and fifty-nine applicants were taken chest X-ray and 17.2 per cent were found abonrmal. For each 1,000 applicants, 46 Pulmonary calcification and fibrosis, 45 chronic bronchitis, 27 pleural thickening and adhesion, 20 pulmonary tuburculosis, 11 anomalies of the rib, 10 pulmonary infiltration and 21 others diseases were found. 8. Lumber X-ray examination showed that 23.9 per cent (372 applicants) were found abnormal. For each 1,000 applicants, 77 osteoarthritis, 56 lumbarization, 15 fracture of vertebrae, 15 spondyloarthritis, 14 deformity of vertebrae, 13 spina bifida, 12 sacralization, 12 spondylolysis, and 5 others diseases were found. 9. In total, 47.9 per cent of 1,559 applicants failed the physical examinations, and the main causes for the failure were shown to be 7.1% of anomalies of spine, 6.3% of osteoarthritis, 4.7% of pulmonary calcification and fibrosis, 4.6% of chronic brochitis, 3.6% of hypertension (only), 3.4% of fracture of vertebrae. 3.1% of underweight(under 57.0kg), 2.0% of spondyloarthritis, 2.0% oe pulmonary tuberculosis, 1.7% of pleurisy, 1.0% of spina bifida, 1.5% of syphilis, 1.5% of color blindess, and 1.0% of underheight(under 160.0cm).

The $\beta$-lactamase gene was cloned into E. coli DH5$\alpha$ from Bacillus sp. J105 with strong resistance against $\beta$-lactam antibiotics. The chromosomal DNA was partially digested with Sau3AI and ligated to BamHI digested pLAFR3. $\beta$-Lactamase positive clones were obtained by using in vitro packaging kit. The pKL11-${\Delta}4.6$ with $\beta$-lactamase activity was obtained by subcloning of the recombinant plasmid ($\beta$-lac +). The 6.5 kb fragment in the subcloned plasmid was sequenced. The DNA fragment that contains the $\beta$-lactamase gene encodes 309 amino acids. The 0.17 kb upstream region was similar to those of B. thuringinesis and B. cereus with 97% identity. The deduced amino acids sequence was also similar to those of $\beta$-lactamase from B. thuringinesis and B. cereus with 97% and 94% identity, respectively. The phylogenetic tree also showed the relationships of the $\beta$-lactamase gene of Bacillus sp. J105 to genetically related that of other Bacillus strains. Analysis of expression pattern of the pKL11-${\Delta}4.6$ in E. coli, revealed that the secretion efficiency of $\beta$-lactamase was $4{\sim}5%$ and the molecular weight was as same as that of original $\beta$-lactamase (31 kDa) from Bacillus sp. J105.

The aim of this study was to identify an effective control method of metabolic syndrome (MS) and oral diseases by investigating relationship between of MS and periodontal disease, tooth loss of the adult men and woman. We analyzed and concluded as follows, using a nationwide representative sample, in 8,225 middle senior citizens based on raw data of the 5th National Nutrition Survey in 2010, 2012. The data were analyzed by descriptive statistics, chi-squared test, and logistic regression using SAS ver. 9.2 program. The results are as follows, for correlation of metabolic component to periodontal disease, it was found that in men, the periodontal disease odds ratio of the group with abnormal fasting blood glucose increased 1.27 fold (95% confidence interval [CI], 1.04~1.54), and in woman, the odds ratios of the group with abnormal high density lipoprotein cholesterol increased 1.45 fold (95% CI, 1.22~1.72) and the odds ratio of the group with abnormal obesity increased 1.44 fold (95% CI, 1.17~1.77). For correlation of MS to periodontal disease, it was found that the odds ratio of periodontal disease in the woman at-risk group increased 1.55 fold (95% CI, 1.19~2.01) and that of the group with MS increased 2.25 fold (95% CI, 1.68~3.02). For correlation of woman's metabolic component to missing teeth, it was found that the odds ratio of group with abnormal blood pressure increased 1.41 fold (95% CI, 1.10~1.82). For correlation of woman's MS to missing teeth, it was found that the odds ratio of missing teeth in the group with MS increased 1.48 fold (95% CI, 1.07~2.04). It is considered that a public health project comprising preventive and systematic disease management is necessary for controlling MS and oral disease. The findings of the study are expected to lay the foundation for the development of oral health promotion programs.

In order to prepare the fundamental data for the improvement of noisy working environments and the effective hearing conservation program on workers exposed to industrial noise, the authors surveyed the working processes and evaluated the noise levels on 56 manufacturing industries in Pusan area from April to July in 1985. The results were summarized as follows : 1. The noise level was the highest in shipbuilding and repairing(95.6 dBA), and followed by steel rolling(94.0 dBA), manufacture of motor vehicles(93.1 dBA), manufacture of fishing nets(92.9 dBA), manufacture of testiles(92.5 dBA), iron and steel foundries(89.3 dBA), manufacture of metal products(89.1 dBA), preserving and processing of marine foods(87.0 dBA), manufacture of rubber products(85.3 dBA), manufacture of plywood(84.9 dBA) and manufacture of paints(84.5 dBA). 2. Among fifty surveyed working processes, the noise level of twenty-one processes (42%) exceeded the threshold limit value for 8 hours per day. 3. As the allowable exposure times by governmental threshold limit values to industrial noise level(dBA), cocking of shipbuilding and repairing and plating(CGL) of steel rolling were the shortest(30 minutes), and followed by assembling(rivet) of manufacture of motor vehicles(1 hour) weaving of manufacture of textiles and shot, machine, pipe laying of shipbuilding and repairing(2 hours). 4. By the result of octave band analysis on noisy working processes in excess of 90 dBA, the sound level was the highest at 2,000 Hz or 4,000 Hz. 5. It was recognized that the measurement of overall sound pressure level was also effective as octave band analysis in evaluating the industrial noise.

This study is aimed to analyze problems of police budgetary execution and to suggest better ways for establishing effective budget implementation as well as legitimacy of securing budget in the field of police work. For this purpose, this paper analyzed the annual reports on police budgetary execution, from 2009 to 2012, conducted by National Assembly Budget Office. In result, most parts of the police budgetary execution were not satisfied with the audit standard, and especially in terms of management of budgetary execution, it showed 40% in inappropriateness. In addition, excessive and underestimate appropriation in the police budgetary execution, which happened frequently in other offices, was recorded on the second place. 10% of the amount of budget was executed for ordinance violence. Given results analyzed from each division, Transportation Division occupied 40% of the amount of related problems and all of types in the field did not meet the audit standard, thus it is required to manage budgetary execution effectively. In terms of Public Safety Division, the problem was related to budgetary allocation prior to execution, such as overlap in other works, excessive and underestimate appropriation, and inappropriate business plans. Director General for Planning and Coordination did not meet the standard of law system maintenance, Given the light of the result of analyzing programs, traffic safety and securing communication was the most problematic and support for police administration, crime prevention and protecting the disadvantaged, educating professional police officers, and establishment of policing infrastructure were required to be reformed in sequence. In order to resolve these problems, it is demanded to check budgetary execution and the process in business plans on a regular basis. Additionally, in case of using budget in inappropriate parts, tough penality including reduction of budget in related to the local police should be implemented to increase the importance of budgetary execution. Moreover, because of the fact that a part of problem of budgetary execution was originally caused by the budgetary allocation, it is advised to allocate police budget using the budget proposal of National Finance Act and Ministry of Strategy and Finance.

The purpose of this study is to find out methods to control, regulate and prevent sexual violence and provide guidelines for sex education in middle school. This study was conducted to examine factors in relation to sexuality, attitudes toward women, experience of sexual contact, frequencies and kinds of pornography with which they had contact, and sex education. For the data collection, a survey was conducted from September 25 to October 1, 1997 by using prepared questionnaires. Questionnaires were given to 503 students from three different kinds of middle schools in Seoul, Boys, Girls, and Coeducation schools. The data analyses used a PC-SAS. Each item was examined by frequencies and percentage. To compare Boys with Girls, I applied a T-test. In addition, with the kinds of school type, I applied anANOVA, ${\chi}^2$. Moreover, For investigating and analyzing each category, I categorized knowledge and attitude of sexuality, with precautionary measures of sexual violence. After that I applied T-test, ANOVA, and a Pearson's correlation for each category. The instruments of this study consisted of 9 domains. (1) General characteristics of the respondents (2) 9 questions about the interaction between he/she and his/her parent. (3) 12 questions, concerning A Scale for Attitudes of Adolescents Toward women(AWSA). (4) 26 questions related to sexual knowledge. (5) 25 questions about sexual attitude (6) strategies for prevention of sexual violence-33 questions (7) 5 questions related to sexual behavior (8) the experience of contact with pronography. (9) the experience of sex-education. The major results were summarized as follows; 1. Like many researches, This study shows that the girls are more eqalitarian than boys. The girls mean ($40.90{\pm}3.67$) is significantly higher than boys ($34.72{\pm}3.77$). Most Koreans have believed that there are many differences between men's roles and women's ones, because of confucianism which had been implied in most thought and ideas since the Lee dynasty. Therefore, the result is not surprising at all. 2. Most students answered correctly the questions of sexual knowledge. The girl's score was higher ($Mean{\pm}SD$ : $48.88{\pm}2.39$) than the boys' ($Mean{\pm}SD$ : $46.95{\pm}3.90$)(p 0.001). Nevertheless, the hypothesis that sexual knowledge influences sexual attitude and its behavior was rejected. 3. When twenty-five questions were asked about sexual attitude, the girl students investigated were found to have a more propre sexual attitude than that of the boys. A significant difference was found between boys and girls(p=0.001). The result shows that a person who has more experience in viewing pornography and who smokes will have a more distorted view of sexuality. 4. There are many students who have experienced of sexual contact. They need to take a sex education program about contraception and prevention of sexually transmitted diseases. Systematic and concrete sex education is one way to lead them to proper sexual behavior. 5. Most respondents rejected stereotyped attitudes towards women. Boys, however, were more likely to accept stereotypes of Women. The girl's mean($Mean{\pm}SD$ : $40.90{\pm}3.67$) is higher than the boys($Mean{\pm}SD$ : $34.72{\pm}3.77$)(p=0.0001). 6. Many boys ignored the rules for prevention of sexual violence. A boy or a girl who has more experience of sexual contact over kiss and sex-typed neglected the rules, too(p=0.001). Today, there is increasing juvenile delinquency related to sexuality. This study provided the basic material for a preventive education system. I believe that a systematic and concrete sex education system can be helpful for adolescents and promote their responsibility as well as cultivate morality about sexuality. As a result, juvenile delinquency can be decreased. This study is basically aimed to provide information for a prevenative education system of sexual violence. Further research is recommended to evaluate programs in schools.

The primary purpose of this study was to identify factors affecting health promoting lifestyles of college students on the basis of Pender's Health Promotion Model. The subjects were 1,159 students of one university in Seoul. These data were collected by self reporting questionnaire from April 19 to May 3, 1993. This study examined health promoting lifestyles, cognitive-percep-tual factors: perceived health status, perceived importance of health, health locus of control, and health conception, and modifying factors: sex, grade, major, residence type, and attendance at a health care course. The instruments used in this study were Health Promoting Lifestyle Profile by Walker et al. (1987), Health Value Scale by Wallston et al. (1976), Health Locus of Control by Wallston et al. (1978), and Health Conception Scale by Laffrey(1986). The data were analyzed by Cronbach's $\alpha$, mean, standard deviation, percentage, t-test, ANOVA, Pearson's Correlation Coefficient, and Stepwise Multiple Regression with SPSS PC+ Program. The results were as follows : 1. The means of health promoting lifestyles revealed total 3.33, self actualization 3.74, health responsibility 2.72, exercise 2.80, nutrition 3.55, interpersonal surpport 3.76, and stress management 2.96. Interpersonal support showed the highest score and health responsibility showed the lowest score. 2. No significant differences between sex, grade, major, and residence type, and health promoting lifestyles Were founded(p>.05). Attendants at a health care course showed a significant higher score than nonattendants (p<.001). Male showed a significant higher score in exercise subscale, female showed significant higher scores in health responsibility, nutrition, interpersonal support, stress management subscales(p<.001), residence type showed a significant difference in nutrition subscale(p<.001). 3. No significant differences between perceived health status and sex, grade, major, residence type, and attendance at a health care course were founded(p>.05). Perceived importance of health showed no differences among sex, grade, major, and residence type(p>.05), showed only in attendance at a health care course (p<.001). Attendants at a health care course showed a significant higher score than nonattendants(p<.001). No significant differences between health conception and sex, grade, major, and residence type were founded (p>.05), only significant difference between health conception and attendance at a health care course was founded(p<.05). Nonattendants showed a significant higher score in clinical health conception, attendants showed a significant higher score in wellbeing health conception(p<.05). 4. A significant positive correlation between health promoting lifestyles and perceived health status was founded(r=.2415, p<.001). A significant positive correlation between health promoting lifestyles and perceived importance of health was founded (r=.1475, p<.001). The health promoting lifestyles revealed significant positive correlations in internal and powerful others locus of control (r=.3187, p<.001: r=.1475, p<.001), but revealed a significant negative correlation in chance locus of control(r=-.997, p<.001). A significant positive correlation between health promoting lifestyles and clinical health conception and wellbeing health conception were founded (r=.1241, p<.001 : r=.3047, p<.001). 5. Perceived health status was the highest factor predicting health promoting lifestyles of college students(R=.3415, $R^2=11.62$). Perceived health' status, perceived improtance of health, internal locus of control, wellbeing health conception, powerful others locus of control accounted for 28.19% in health promoting lifestyle patterns. In conclusion, college students who reported more helath promoting lifestyles evaluated their health positively, perceived importance of health highly, perceived their health as affected by theirselves, powerful others but not by chance or luck, and accepted health as high level wellness rather than merely the absence of illness. Those who attending at a health care course had healthier lifestyle patterns. And attendance at a health care course had significant. correlations in these cognitive-perceptual factors. Further studies are required to identify reasons of attending a health care course, and to compare health promoting lifestyles pre-post attending a course related to health care.

The purpose of this study was to describe the perceived burden of the terminally III patients's caregiver and to analyze relationship between the perceived burden and the various demographics, illness characteristics, family relationships, and economic factor of the family & patients. The sample of 132 caregivers who care for the terminally III patients Kyung-Gi province, Seoul, Korea. The period of this study was from August to September, 2002. The perceived burden of the family caregiver was measured by the burden scale(20 items, 4 point scale) developed by Montgomery et al. (1985). The Data was analyzed using SAS-program by t-test and ANOVA. The results were as follows; 1. The mean of the family caregiver's burden score was 3.02. The score showed that caregivers perceive severe the level of burden. The hight items of the family caregiver's burden were' I feel it is painful to watch patient's diseases'(3.77). 'I feel afraid for what the future holds for my patients'(3.66), 'I feel it reduced to amount of privacy time'(3.64). 2. The caregiver's burden was significantly related to patient's gender(F=3.17, p= 0.0020), patient's job(F=2.49, p=0.0476), caregiver's age(F=4.29, p=0.0030), and caregiver's job(F=2.49, p=0.0476). 3. The caregiver's burden according to illness characteristics showed no significant difference. 4. The caregiver's burden was significantly associated with patient's family relationship (F=4.05, p=0.0041), patient's care mean period in a day(F=47.18,
