The number of single households in Korea has been sharply increasing due to dissolution of the family community and changes in housing culture. Therefore, there is a need to develop a plan for diagnosis of changes in the housing market in response to a rapid increase of single household to suggest a proper direction of housing policy. This study was conducted to clarify the factors influencing housing occupancy type targeting a single adult household. To accomplish this, a cross-sectional analysis was conducted using the multi-nominal logit model and the Korea Welfare Panel's 9th survey materials. Occupants of ingle households in their 20s and 30s were found to be much poorer than those in their 40s, or older. Additionally, single household in their 20s and 30s, the characteristic of a household having an influence on the choice of housing occupancy type showed a result in a different direction even from the same household characteristic of those in their 40s, or older. Finally, the characteristics of occupants of single households in their 20s and 30s showed room for improvement through public support. Overall, the results of this study implied the need to inquire into the government's periodic support in more diverse ways.

The purpose of this study was to survey the anti-HBs positivity and titers of antibody in current students who received nationwide vaccination against Hepatitis B virus which targeted infants in 1995. The subjects were 262 students in Gyeongnam province from April 2014 to October 2014. The positive rate of anti-HBs was 55.3% (145 people) and the negative rate of anti-HBs was 44.7% (117 people). Positivity was shown to be higher in women than men. However, there was no statistically significant difference. Of the HBV-vaccinated subjects, 117 (44.7%) had anti-HBs titer <10, which is judged to be negative, 126 (47.8%) had anti-HBs titer 10-499.9 mIU/mL, which is judged to be positive, and 22 (7.3%) had anti-HBs titer more than 500 mIU/mL. The rate of anti-HBs with lower titer (10-99.9 mIU/mL) was 62% in the positive group. Classifying the antibody titer according to age, the rate of anti-HBs positivity in titer with less than 100 mIU/mL was indicated to be 78.3% in cases of 19-20 year old and 46.7% in 21-22 year old, 52.3% in 23-24 year old. A case of the lower titer with 10-99.9 mIU/mL, showed significant difference according to age. As a result of research, the antibody titers is decreased depending on the passage of time. Hence, the checking of anti-HBs titer is needed after Hepatitis B vaccination and many healthy adults will need periodic boosters of hepatitis B vaccine to maintain production of antibody to hepatitis B surface antigen.

In order to evaluate the factors related to therapeutic compliance of hypertensive patients in small and medium scale industry, the questionnaire survey and the blood pressure measurement were performed on 138 hypertensive patients who were reported to have C or $D_2$ result of hypertension at the workers' periodic health examination from March to November 2001. The contents of questionnaire included the informations of factors related to therapeutic compliance of hypertensive patients such as, age, sex, marital status, income, education levels, scale, occupation, work duration, smoking and drinking habits, exercise, family history, stress and A type personality, employer's concern, organizational culture, health status, awareness, knowledge and attitude toward the needs of hypertension treatment, and experience of health education. The results of the study were as follows: 1. The proportion of those who were compliant to the treatment of hypertension was 41.3% of subjects. Among small scale industry less than 50 employees, the rate of therapeutic compliance group was 27.5% and therapeutic noncompliance group was 72.5%. Among medium scale industry more than 50 employees, the rate of therapeutic compliance group was 60.3% and therapeutic noncompliance group was 39.7%. 2. Among therapeutic noncompliance group, 95.1% of patients were aware of the fact that workers have hypertension, and 77.8% of patients got 6-10 marks of hypertension related knowledge. For health education, 27.2% were experienced and 34.6% said no intention to participate. And for hypertension treatment, 9.9% said no need to get the treatment and 44.4% said have no idea whether get treatment or not. 3. The significant factors related to therapeutic compliance of hypertensive patients in small scale industry were work duration, A type personality(anger), health status, attitude toward the needs of hypertension treatment, and experience of health education. 4. The significant factors related to therapeutic compliance of hypertensive patients in medium scale industry were age, occupation, subjective symptom, attitude toward the needs of hypertension treatment, and experience of health education. In consideration of above findings, it was suggested that in order to improve the therapeutic compliance in small and medium scale industry hypertensives, it be necessary to change attitude, perception, knowledge and treatment of hypertension by various methods such as effective health education and individually consulting programs by occupational health professional.

The study was conducted to analyze employees' and employers' awareness of occupational health programs for the purpose of evaluating the effectiveness of the program employed in small-scale enterprises (SSE). The 400 SSE that have under 50 employees and have been supported by the Government were selected for mail survey, and 120 employers and 318 employees of 183 factories returned the questionnaires. The results are as follows; 1) 33.8% of employees were not aware of the fact that their factories have been supported by Government, and 69.1% of employees did not know who was the monitor of that program. Only 147% of employees and 35.5% of employers agreed that the supported program reflected their opinions well. 2) 45.1% of employees participated in health education classes more than once. But only 15.6% of them considered the classes as very helpful. 21.1% of employers were much aware of health education schedule, and 44.2% reported that it was helpful for the prevention of occupational diseases. 3) 68.8% of employers were aware of the possibility of occupational diseases that could occur in their factories. And 36.5% of employers reported that some criteria were used for job reallocation to their employees. But only 9.7% of employees were assigned new job based on the result of health status examination. 4) 65.6% of employees were aware of the periodic evaluation for work environment, and 43.3% knew the evaluation results. Among participated SSE, 5.9% have a planning department for improving work environment, and 46.2% actually carried out the program for improving work environment. The findings showed that the employers and employees of SSE had insufficient knowledge of the occupational health program that have been employed in their workplace. It is essential to lead more active participation of employers and employees in their occupational health programs so as that the programs are to improve their health status as well as work environment more effectively.

This study identified the dynamic process of sandbar and vegetation distribution of the sandbar on the Tan-cheon River. The study area is located in the lower reaches of the Tan-cheon River that has been managed as an Ecosystem Reserve Area since 2002. For the study, the geomorphological process was analyzed through mapping analysis using a satellite image followed by analysis of the vegetation distribution through an on-site survey. The major findings were as follows : First, In the fluvial geomorphic process, various kinds of sandbars were developed in 1990s, the morphologic characteristics changing continuously. Second, In the distribution of vegetation on the sandbar, the sandbar shore was covered with bare sand substrate or intermittent annual vegetation because of the periodic fluctuation of the water-level due to intensive disturbances. Third, In the relationship between the sandbar formation and vegetation, four types of sandbars were classified: channel-shore stable bar, channel-shore unstable bar, mid-channel stable bar and mid-channel unstable bar, according to the fluvial disturbance & vegetation process. The study verifies that the vegetation distribution is reciprocally related to the geomorphological process. Accordingly, it is meaningful in the selection of plant species and the planting area of the sand bar. However, it is limited to the planting guidelines on river restoration projects. More diverse on-site experimental studies should be conducted.

Objectives : Because elementary school children are sensitive and prevalent to dental caries, oral health care program for the elementary school children (ESOHCP) should be met the first priority for the national oral health care program. This study was performed to proposed the guidelines for executing the efficient ESOHCP through the evaluation of present oral health care and education status based on the attitudes and opinions of health teachers. Methods : Subjects were 181 health teachers those are a part of the total 273 elementary school health teachers in Busan. From April to June 2001, questionnaire survey on the teacher's attitude and opinion, present status of oral health care and education in their own school was done. Data was analyzed by $\chi^2$-test, t-test, ANOVA using SAS (ver 6.21) program. Results : Mean age of the teachers was 40 years (24~58 years) and mean scale of the subject school was 32 classes (5~58 classes). Above 90% of them agreed with the necessity and importance of ESOHCP, but actual level of concerning was lower. They gained the informations about oral health mainly from media (33%), PC net (26%), academic society (25%), and more used internet (p=0.012) in younger generation. Though most of them (96%) had a specified school dentist, only 58% had the experience of periodic oral health examinations in their own school. The major experienced ESOHCP was fluoride brushing and contest to choose the best healthy teeth. Oral health education given by the teachers was not professional but their own. About half (42%) of the teachers had never taken education during last one year. Major education materials were VTR tape (79%), teeth model (64%), CD (55%), booklet (50%), etc., and the teachers' preference was also VTR tape (43%) and CD (41%). When they need education materials, they frequently request to dentist's association (36%), academic society (35%), but rarely to dental clinics or dentists (6%). They prefer that two times (46%) of annual oral health education, with the contents of regular brushing (53%), but lower regular visit to clinics (13%). The interest to oral health care (p=0.016) increased with teacher's age. And, they agreed regular students education in case of higher interest(p=0.044). Intention about join in the model school program was decreased with scale of school (p=0.002). Conclusions : This result showed that the present status of ESOHCP is still insufficient. It considered that the health teachers' interest and role is most important for the maintenance and success of ESOHCP. The professional and efficient education program would be focused on the health teachers to induce drive on ESOHCP.

Risk of radiation worker and radiation workplace are being mainly assessed by exposure dose. But, the radiation used in radiation workplace and the work environment are different. Because the nondestructive work environment varies depending on the work subject, the existence and nonexistence of shielding board, and so on. So, we need to consider the various factors in effective radiation protection aspect. We conducted a survey of radiation workers with over two years' experience in NDT workplace and heared the thoughts of experts. As a result, radiation source, exposure dose, current status of workplace management, workers with personel dosimetry problem and status of periodic regulatory inspection were chosen as main factors of radiation risk index model. Also, we primarily set weighting factors in order of importance based on questionnaires. Finally, we determined weighting factor for details of main factors through the professional advice. Therefore, we will be able to develop the radiation risk index model for assessing the risk of nondestructive test workplace based on main factors that are selected through this study.

Periodic and systemic disaster management has become more important than ever owing to the recent continuous occurrence of disasters, such as fires, earthquakes, and flooding. This management goes beyond simple disaster preparedness, which was introduced minimally under the existing legal system. For effective disaster management, facilities should be managed through regular maintenance on a daily basis, and in the case of an emergency, intuitive and accurate communication is essential regarding the situation and purpose. BIM manages the entire building property data using the effective 3D visualization model, so it can be used for various management purposes from design to facility maintenance. In this study, through an expert survey on the use of services in a BIM-based integrated disaster information system, the available areas of BIM data were organized in terms of facility information management, 3D visualization, and disaster control. Later, through the use service and DB definition within the BIM-based disaster integration information system, the main facilities monitoring and response services based on BIM and BIM-based spatial management service are proposed. Based on this study, it is hoped that the BIM-based application service functions within the system will be implemented to enable an effective system response.

Due to the growing awareness and demand for corporate social responsibility, the corporate activities designed to make a social contribution are becoming increasingly diversified. Nonetheless, according to a periodic survey, the public has become dissatisfied with the social contribution activities of domestic corporations. The perceptions of the social contribution activities of domestic corporations and the public were found to be quite different. In this study, the Social Contribution Activities were classified into three factors, "Socio-Cultural Resource Activities", "Indirect Social Resource activities" and "Economic Resource Activities", and the effect of each factor on the inter-firm connected activities and achievements of local development were analyzed. Firstly, the "Socio-Cultural Resource Activities" and "Indirect Social Resource Activities" were shown to have a positive effect on the Inter-firm connected activities in the community. Secondly, it was found that the more active the Inter-firm connected activities were in the community, the bigger their positive effect was on the achievements of local development. Thirdly, the "Economic Resource Activities" were shown to have a positive effect on the achievement of local development. Fourthly, "Socio-Cultural Resource Activities" and "Indirect Social Resource Activities" were shown to have a positive effect on the Inter-firm connected activities and an indirect positive effect on the achievement of local development. Based on this research, we quantitatively determine the relationship between the corporate social contribution activities and performance.

As a part of the short-period variability survey (SPVS) at Bohyunsan Optical Astronomy Observatory, we obtained time-series BV CCD images in the region of the open cluster NGC 1039 (M34). The observations were performed for 22 nights from July 29, 2008 to September 26, 2010. We also made LOAO observations for 10 days from September 18, 2009 to October 30, 2010 to confirm the small variabilties of ${\delta}$ Scuti-type variable stars. In this paper we presented the observational properties of 28 variable stars found in the region. They are seven ${\delta}$ Scuti-type variable stars, two ${\gamma}$ Doradus-type variable stars, four-teen eclipsing binary stars and five semi-long periodic or slow irregular variables, respectively. Only three variables were listed in the GCVS and the rest are newly discovered ones. We have performed multiple-frequency analysis to determine pulsation frequencies of the ${\delta}$ Scuti-type and ${\gamma}$ Doradus-type variable stars, using the discrete Fourier transform and linear least-square fitting methods. We also have derived the periods and amplitudes of 12 eclipsing binaries from the phase fitting method, and presented the light curves of all variable stars.
