BACKGROUND: Adolescence is the starting period for health behaviors that will affect their lives throughout adulthood. Unhealthy behaviors in Korean adolescents have increased compared to previous generations. To promote health behaviors in this group, a comprehensive measurement of Korean adolescents' health behaviors is necessary. Most previous studies have used revised instruments, which were developed in other cultures, but not tools developed to measure health behaviors based on the perspectives of Korean adolescents. Identifying the perception of health behavior among Korean adolescents is important for the future of health promotion. Therefore, this study was conducted to investigate Korean adolescents' perceptions of their health behaviors. METHODS: A qualitative study was conducted to attain a condensed and broad description of the health behaviors that adolescents perceived as health-promoting behaviors or risk behaviors. From October to December 2008, 61 Korean middle and high school students were interviewed on their perceptions of health behaviors. Data were analyzed using inductive qualitative content analysis. RESULTS: Korean adolescents reported health behaviors related to stress, mental health, sleep habits, dietary habits, weight control, physical activity, hygiene habits, safety, computer use, substance use, health screening and others. CONCLUSIONS: The results provide socio-cultural characteristics about the perception of health behaviors among Korean adolescents and should contribute to guiding assessment of health behaviors in Korean adolescents and provide a reference for developing valuable health-promoting interventions based on these characteristics.

The purpose of the study was to test the reliability and validity of the Korean version of Children's Health Locus of Control Scale(CHLC), an instrument designed to measure health locus of control in children aged 7 to 12. The scale was administered to 467 children in grades 4 to 6, enrolled in 2 elementary schools located in city. The mean age of the subject was 10.03(SD=1.33). The findings were as follows: 1. Cronbach alpha coefficient for internal consistency was .69 for the total, and .67, .65, and .56 on the respective subscales. 2. Construct validity was supported through factorial isolation of three theory consistent subscales: internal, chance, and powerful others. Two items did not fit well with the originally developed subscale. The total percent of variance explained by 3 factors was 34.5%. The result of the factor analysis according to Kaiser's criterion revealed that the scale was consisted of 5 factors. But, The items of the subscales were rather inconsistent with the dimensions of the locus of control concept. 3. There were significant differences according to parent's educational level and occupation, and birth order on the scores of the CHLC. There were no significant differences according to grade level and sex. 4. The score of the CHLC was significantly correlated with the self concept of the children(r=.14, p<.001). The result indicated that the Korean version of Children's Health Locus of Control Scale was valid and reliable in measuring health locus of control concept in children, even though further research is required to reconfirm and increase the reliability of the instrument. CHLC could be used for study explaining the health related behavior of the children and research project to health education program.

The measurement of systolic time intervals has become one of the established quantitative noninvasive tests of cardiac function, especially of left ventricular performance, and remain one of the simplest and most reliable to perform. In an attempt to obtain the normal data of the systolic time intervals, we conducted a study in 89 normal Koreans of 43 males and 46 females. The measurements are obtained from the simultaneous high speed recordings (100mm/sec) of electrocardiogram, phonocardiogram, and indirect carotid arterial pulse. The results were as follows. 1. The QS2I, LVETI, and PEPI was 521+/-18 msec, 409+/-13msec, and 112+/-12 msec in males and 529+/-14 msec, 408+/-15 msec, and 121+/-11 msec in females, respectively. 2. The PEP/LVET ratio was 0.29+/-0.04 in males and 0.31+/-0.05 in females. 3. The QS2I and PEPI were significantly more lengthened in femals than in males, but other systolic time interval indices did not significantly relate to the sex. 4. The A2D was significantly shortened with age, but other systolic time intervals did not change with age. 5. According to the regression equations of QS2, LVET, and PEP to the heart rate, QS2 and LVET related more inversely to the heart rate than PEP.

PURPOSE: To compare the incidence between author's first and current report on urinary tract stone in patient with spinal cord injury and to evaluate the effectiveness of recent developed in medical technology and care on in treating the patients. MATERIALS AND METHODS: We reviewed urinary tract stone in 257 patients with paraplegia or quadriplegia after spinal cord injury. These patients were diagnosed retrospectively by KUB and intravenous urography at the Korea Veterans Hospital during 10years from January, 1984 to December, 1993. We evaluated and compared the overall incidence, incidence of specific location of urinary tract, recurrent rate, incidence according to the level of spinal cord injury, and the duration of development in urinary tract stone. RESULTS: Total patients were 257 with 186(72.4%) paraplegia and 71(27.6%)quadriplegia. Overall incidence of the stone was 16.0% in this study and 38.1% in the first study. Incidence of the stone in individual organ ;5.5% in kidney, 1.2% in ureter, and 13.6% in urinary bladder. The recurrent rate was 29.3% in this study and 40.6% in the first study. Incidence of the stone according to the level of spinal cord injury was as follows;15.6% in cervix, 17.1% in upper thorax, 17.9% in lower thorax and 13.9% in lumbar. The stone developed during the first 4 years and between 12 to 16 years following spinal cord injury was 28.3% each. CONCLUSION: Overall incidence and recurrent rate of urinary tract stone was obviously decreased since the first study. Highest incidence of the stone occurred in urinary bladder and in patient with lower thoracic spinal cord injury, which is similar to first report. Peak incidence of the stone was in the first 4years, and another peak was in 12-16years after spinal cord injury. The decreased overall incidence of urinary tract stone maybe attributable to the development in medical technology and care, and active rehabilitation.
