The aim of this study was to determine the effectiveness of diagnostic range for BMD measurement tools(DEXA, QUS, and RA) to health examination in transitional ages. In standard T-score -2.5 of DEXA, cutoff value by RA is -1.675(sensitivity: 70.0%, specificity: 63.7%) and cutoff value by QUS is -1.733(sensitivity: 70.4, specificity: 59.5%), also T-score -3.0 of DEXA, cutoff value by RA is -2.325(sensitivity: 70.0%, specificity: 42.9%) and cutoff value by QUS is -2.323(sensitivity: 70.4, specificity: 56.8%). There was, however, no significant difference in standard DEXA(lumbar spine and femur) between RA and QUS by repeat measurement(precision), and correlation were without effect. ROC analysis showed that all methods are qualified for BMD measurement tools to health examination in transitional ages; however, the different sensitivities and specificities of the methods, as well as age and gender, calibration parameters for diagnostic tests have to be considered.

The study is to observe a degree of relation between quality of life and a degree of walking exercise for adult residents of cities of Korea. From data of the 4th round 3rd-year Korea National Health and Examination Survey, 7,851 in which 3,892 were male residents and 3,959 females, were selected as subjects, excluding 723 who didn't answer at least more than one question for 5th degree of EQ-5D and physical activities. As a result, quality of life showed statistically significant relation among gender, education level, spouses, average monthly income, stress, a number of chronic diseases, health recognition and whether walking exercise undertaken. Especially one who carried out walking exercise showed higher quality of life than one who did not. This showed more significant difference of quality of life between whether the exercise was undertaken and whether it is intensified or intermediate. Therefore, in accordance with results of this study, it is necessary to develop an effective exercise program that is designed to let residents to exercise in a regular basis and to guarantee a sustainable support from government.

The purpose of this study was to investigate factors affecting self-directed learning of workers. For this purpose, 335 workers were surveyed in two cities in the northwestern part of Chungcheongnamdo. The research was carried out by difference test to identify the diffrence of self-directed learning according to general characteristics and by correlation analysis of main variables. Also in order to identify the effect of hope and growth mindset on self-directed learning, hierarchical regression analysis was conducted by diving the group into employee-level and higher employee-level. The main results are as follows. First, Self-directed learning differed by gender. Second, correlation analysis revealed that hope, growth mindset and self-directed learning were positively correlated. Third, regression analysis showed that the pathway thinking of hope and the intelligence of the growth mindset influenced self-directed learning of employee-level workers. And it showed that the pathway thinking of hope influenced self-directed learning of higher employee-level workers. Finally, we discussed policies to enhance workers' self-directed learning based on positions.

The ultimate purpose of psychotherapy is to identify covert causes of a psychological problem and then to modify and change the causes. The goal of this study is also to make contribution to SNS addiction intervention program development through exploring the covert causes of SNS addiction which recently became social issue. Previous research identified such overt causes of SNS addiction as maladaptive self-concept (e.g., low self-esteem), maladaptive personality (e.g., strong narcissism) and strong negative emotions (e.g., high level of anxiety). Based on previous research, the study explored early maladaptive schema (i.e., cognitive dimension) and emotion dysregulation (i.e., emotional dimension) as the covert causes of SNS addiction and conceptually developed psychological maladaptive mechanism of 'early maladaptive schema ${\rightarrow}$ emotion dysregulation ${\rightarrow}$ SNS addiction.' As a result of a survey with respondents in their 20's who are at high risk for SNS addiction, the mechanism was confirmed for females. However, a significant relationship of 'early maladaptive schema ${\rightarrow}$ SNS addiction' was found for males. The findings offer an implication that interventions of early maladaptive schema for males and females in their 20's and interventions of emotion dysregulation for females in their 20's can fundamentally help cure their SNS addiction.

Purpose of this study is to compare and analyze effect of exercise intensity in complex training for 8 weeks on leptin, growth hormone, IGF-1, and body composition in middle school with intellectual disability. Subjects of this study were 26 middle school students, 9 in high-intensity group, 9 in middle-intensity group, and 8 in low-intensity group. To compare the difference from different exercise intensity, pre-value before training has been set as covariate and different exercise intensity has been set as independent variable, with changes in leptin, growth hormone, IGF-1, and body composition. Analysis of covariance (ANOVA) has been performed for data analysis and effect size ${\eta}^2$(eta) has been deduced. Result acquired from analyzed data is as following. First, when equal exercise has been imposed on middle school students with intellectual disability, in regard of exercise intensity, it was shown that leptin most decreased in middle-intensity, growth hormone most increased in middle-intensity, and IGF-1 increased in low-intensity. Second, in regard of body composition, low-intensity was most effective in increase of total body weight without fat. Decrease of body fat was most prominent in middle-intensity and increase of bone density, in low-intensity. Also, in further studies, study that differentiates subjects in gender and individual exercise performance is deemed mandatory.

Objectives : Aseptic meningitis is a major cause of Korean childhood morbidity late spring and early summer. However, the nationwide incidences of the disease have not been reported. This study was conducted to evaluate the availability of National Health Insurance data (NHID) for the study of an epidemiological trend in the surveillance of aseptic meningitis in children. Methods : All the claims, under A87, A87.8, and A87.9 by ICD-10, among children below 15 years of age, to the National Health Insurance Corporation, between January and December 1998, were extracted. A survey of the medical record of 3,874 cases from 136 general hospitals was peformed. The availability of the NHID was evaluated by the three following methods: 1) The diagnostic accuracy (the positive Predictive value : proportion of the confirmed aseptic meningitis among the subjects registered as above disease-codes in NHID) was evaluated through a chart review, and according to age, gender, month and region of disease-occurrence. 2) The distribution of confirmed cases was compared with the distribution of total subjects from the NHID, for subjects in General hospitals, or the subjects surveyed. 3) The proportion of confirmed CSF test was confirmed, and the relating factor, which was the difference in CSF-test rate, analyzed. Results : Among 3,874 cases, CSF examinations were peformed on 1,845 (47.6%), and the CSF-test rates were different according to the medical utility (admission vs. OPD visit) and the severity of the symptoms and signs. The diagnostic accuracy for aseptic meningitis, and during the epidemic (May-Aug) and sporadic (Sept-Apr) periods, were 85.0 (1,568/1,845), 86.0 (1,239/l,440) and 81.2% (329/405), respectively. The distributions by age, sex, month or period (epidemic/sporadic) and region, in the confirmed cases, were similar to those in the NHID, in both the subjects at General hospitals and in those surveyed, to within ${\pm}7%$. Conclusions : In this paper, the NHID for the subjects registered with an aseptic meningitis disease-code might be available for an epidemiological study on the incidence-estimation of childhood aseptic meningitis, as the NHID could include both the probable and definite cases. On the basis of this result, further studies of time-series and secular trend analyses, using the NHID, will be peformed.

Objectives. Changes in lung function are frequently used as biological markers to assess the health effects of criteria air pollutants. We tried to formulate the prediction models of pulmonary functions based on height, weight, age and gender, especially for children aged 12 years who are commonly selected for the study of health effects of the air pollution. Methods. The target pulmonary function parameters were forced vital capacity(FVC) and forced expiratory volume in one second(FEV1). Two hundreds and fifity-eight male and 301 female 12-year old children were included in the analysis after excluding unsatisfactory tests to the criteria recommended by American Thoracic Sosiety and excluding more or less than 20% predicted value by previous prediction equations. The weight prediction equation using height as a independent variable was calculated, and then the difference of observed weight and predicted weight (i.e. residual) was used as the independent variable of pulmonary function prediction equations with height. Results. The prediction equations of FVC and FEV1 for male are FVC(ml) = $50.84{\times}height(cm)+7.06{\times}weight$ residual 4838.86, FEV1(ml) = $43.57{\times}height(cm)+3.16{\times}weight$ residual - 4156.66, respectively. The prediction equations of FVC and FEV1 for female are FVC(ml) = $42.57{\times}height(cm)+12.50{\times}weight$ residual - 3862.39, FEV1(ml) = $36.29{\times}height(cm)+7.74{\times}weight$ residual - 3200.94, respectively.
