We conducted validation for asbestos quality control (QC) samples made by the developed method which was presented in our published paper. The main results of the validation study are as follows. The pooled coefficient variations of analytical results in three different concentrations (low, medium, and high concentration) for amosite and chrysotile were less than 20 %, which met the sample homogenicity criteria of NIOSH. Also we confirmed the homogenicity of asbestos samples by using the relocatable field slide. To evaluate the field applicability of the developed asbestos QC samples, the field validation was performed with four proficient asbestos analysts by using the statistical methods of AIHA asbestos PAT program. All analytical results from four asbestos analysts were located in the acceptable range.

This study was designed to develop the evaluation scale for health-grade of families. For this goal the related references and the programs of Healthy-Families-Center were analyzed. In the context with the goals and objects of programs in Healthy-Families-Center the index for the evaluation the health-grade of families was deducted. And the concrete items of health-grade of families in 3 parts(R: relation, M: management, E: environment) was discussed. In order to verify the validity and significance of the scale the survey for 200 samples was performed and the data from 191 samples was statistically analyzed. We suggested the application methods of this evaluation scale for health-grade of families. So the 8 types of families were came out: RME, RMe, RmE, rME, Rme, rMe, rmE, rme. Using this type of families the consulting and counselling for the enhancement of health-grade can be developed. We reached the conclusion that this evaluation scale has to be continuously developed and eleborated because the health-grade of families is one of the most important index for the effect of programs of Healthy Families Center.

This study modifies the present total maximum daily load (TMDL) system of Ministry of Environment and applies to the Anyangcheon watershed. Hydrologic Simulation Program-FORTRAN (HSPF) model is used to simulate both runoff and non-point source pollution, simultaneously, instead of QUAL2E. The drought flow (355th daily flow) is proposed for the target water quantity since it is easier to satisfy low flow (275th daily flow) for the target water quality than drought flow. The increase of discharge is more than the increase of pollutant load except for the period under low flow. The measured unit loads for non-point source are used to consider the regional runoff characteristics. The measured water quantity and quality data are used since the ministry of environment supports only water quality. This analysis results show some reasons for the improvement of the present TMDL system of Korea.

Architectural steel structures with visible tension and compression members are becoming more prevalent as a popular form of construction that reflects the nature of the resistance to the applied loads. These members require the use of structural steel pins at their ends to ensure either axial tension or axial compression in the members. Structural pins have been used as a means of connection for centuries and it would appear that their behaviour is relatively well understood. However, the rules for the design of pins vary quite considerably from code to code and this has caused some confusion amongst consulting structural engineers operating internationally. To provide some insight into this problem, a comprehensive testing program has been carried to examine the influence of parameters such as pin diameter, material properties of the pin, thickness of the loading plates, material properties of the loading plates and the distance of the pin to the edge of the loading plates. The modes of failure have been carefully examined. Based on this study, modifications to current design procedures are proposed that properly take into account the different possible modes of failure.

Purpose: This study is to identify the factors that affect middle-aged workers' health promoting behaviors. Methods: 214 middle-aged workers participated in surveys, and the data were collected from August to September 2012 and analyzed by using descriptive statistics, Pearson's correlation coefficient, and multiple regression analysis with PASW 18.0 program. Results: It was found that among the factors, the degree of job stress (t=7.69, p<.001) and depression (t=6.23, p<.001) were significantly high for type D individuals, while non type D showed meaningful degree of self-related health status (t=-3.66, p<.001) and health promoting behaviors (t=-4.71, p<.001). The notable variable that affected the health promoting behaviors of the middle-aged workers was depression for both type D (${\beta}$=-.357, p= .029) and non type D (${\beta}$=-.325, p<.001) individuals, and this variable accounted for 24.1% and 18.2% respectively. Conclusion: The study revealed that the middle-aged workers showed high degree of job stress and depression that influenced on their health promoting behaviors. Thus, they are recommended to receive health management programs that offer treatment through consulting considering their individual personalities.

Objectives: This study aimed to identify general characteristics of health status and health behavior of adolescents in accordance with their purposes with internet. Methods: Based on Adolescent Health Behavior Online Survey (KYRBS) in 2014, a total of 57,333 adolescents who had used internet were examined in this study. Results: Users for non-academic purposes were associated with male, low grades, low education level of parents, low income level, being apart from parents, being without any consulting partners, being with one parent families, low perceived health status, the experience suicidal ideation and negative health behavior such as alcohol and tobacco. In particular, these trends were appeared strongly by internet users for the purpose of the non-academic purposes. Male among high grades is shown to be mostly Academic internet users and they were more likely to have problems with some health behaviors such as exercise frequency and smoking. Conclusions: Target population should be internet users for only non-academic purposes to prevent internet addiction of adolescents. Internet addiction prevention program should be provided in terms of mental health and problematic behavior. Additionally, health behavior of internet over user for only academic purposes should be concerned.

Communal places for parents to take child-care are very important in activating cooperative child-care(CCC). Therefore, Jeju Special Self-Governing Province has been operating Cooperative-Childcare-Places(CCPs) since 2016. This study analyzed the operational status of the CCPs and presented the model type to provide data for the activation of CCC. Qualitative analyses were applied to the results of interviews with 10 staff members. The common task they considered difficult was recruitment, and there was a big difference in the operation of the regular program depending on the competence of the staff in charge. The lack of support systems, such as education and consulting, has made it difficult for the staff to do their work. Additionly, four models of CCPs were found, a resident self-governing type, a workplace type, an institutional type, and a rural complex type. In conclusion, CCP spaces should be planned and facilities created with a focus on the needs of child-care activities. Second, the role of staff in helping to organize the parents' self-governing committee is crucial. Third, it needs to establish a support system to strengthen the capacity of the staff members.

Objectives : This study aimed to investigate the current job-related characteristics coordinators in East-West Collaborative Medical Practices(EWCMP) and to develop activation plans for them. Method : The participants were 51 personnel who were supporting EWCMP in the 28 institutions. Data were collected with self-administered questionnaires and analyzed with descriptive statistics. Results : The major role of the participants was educating and consulting patients(74.5%) and followed by supporting collaborating physician(70.6%). They assumed to be helpful to make the patients easy to use EWCMP(98%) and to give patients full information what they asked(96%). However, participants responded lack of adequate educational programs and role ambiguity as chief complaints(91.7%). They showed relatively high level of job importance(78.7points on 100points) and job satisfaction(72.8points on 100points). Coordinators were expected to have bachelor and more than 8 years clinical career, and communication skill. Conclusions : Coordinators have played key roles in giving information for the patients and coordinating EWCMP. However their roles and job description was not clear, and educational programs was insufficient as required. Therefore, it is needed to clarify their roles and job description and establish professional educational programs for supporting coordinators.

Purpose: To investigate factors that affect behaviors of reducing exposure to endocrine disrupting chemicals (EDCs) in breastfeeding mothers. Methods: Subjects were 166 breastfeeding mothers who were recruited from January 25 to April 15, 2018. The questionnaire consisted of items associated with behaviors of reducing exposure to EDCs, attitude to behaviors of reducing exposure, subject norms of behavior of reducing exposure, and perceived behavior control. Data were analyzed by t-test, ANOVA, Pearson correlations, and stepwise multiple regression. Results: Factors influencing behaviors of reducing the exposure to EDCs were attitude toward behaviors of reducing exposure, perceived barrier, and period of lactation. The more positive the attitude toward behaviors of reducing exposure was, the lower the perceived barrier. The longer the feeding period, the higher the behaviors of reducing the exposure to EDCs. Conclusions: To enhance behaviors of reducing the exposure to EDCs, it is necessary to develop a positive educational program in breastfeeding department to improve attitude toward behaviors of reducing the exposure to EDCs, decrease perceived barrier, and increase the breastfeeding period.
