OBJECTIVES: The purpose of this study was to make empirical evidence of community based detection, assessment and allocation system for early psychosis. METHODS: We analysed 222 youths who were referred to Seoul Early Management and Improvement Services (SEMIS) for early psychosis during six years from 2007 to 2012. RESULTS: 44% of referrals were from suicide hotline, 23% from web-based SEMIS assessment program, 20% from other service areas such as military services and 11% were self referred. Among 222 youths, 139 (62.6%) were completed Structured Interview for Prodromal Syndrome (SIPS). After SIPS, 23% had untreated or early psychosis, another 17% were found to be at high risk of psychosis and 18% of completed SIPS were found to have other mental illness such as depression, yielding an efficiency ratio of 58%. 70% of youths who were categorized as psychosis or high risk of psychosis or other mental illness were referred to psychiatric hospital or case management services. CONCLUSION: This study shows the effectiveness and limitations of community-based assessment and intervention system for early psychosis. Integrated community program is necessary to improve the efficiency of early intervention and for the better outcomes.

PURPOSE: The purpose of this study was to verify the effectiveness of the model based on the TPB, behavior-related theories, and exercise-related empirical studies in predicting exercise intention and behavior. METHODS: The subjects who participated in this study were 152 middle-aged women. The data were analyzed by use of SAS PC program and LISREL 8.12a program. RESULTS: 1) The overall fit of the hypothetical model to the data was acceptable(x2 24.01(p=0.0043), x2/df 2.67, RMSEA 0.11, standardized RMR 0.04, GFI 0.97, AGFI 0.84, NFI 0.95, NNFI 0.85). 2) Affect, subjective norm, perceived behavioral control and habit were significant determinants of the exercise intention. Attitude and facilitating conditions were not significant determinants. These six variables explained 43% of the total variance of the exercise intention. 3) Perceived behavioral control and habit were significant determinants of the exercise behavior. Intention and facilitating conditions were not significant determinants. These four variables explained 95% of the total variance of the exercise behavior. CONCLUSION: This study shows the model's applicabiltiy in explaining exercise behavior of middle-aged women, and suggests that we should focus on perceived behavioral control and habit rather than intention to improve exercise behavior of middle-aged women.

This study has been undertaken in order to 1) test the effect of health education on the performance of health promoting lifestyle, self efficacy, control and perceived health status in college students, 2) assess whether pretreatment level of self-efficacy, control, and perceived health status predict post-treatment health promoting lifestyle, 3) assess whether pre-to post-treatment changes in self-efficacy, control, and perceived health status predict post-treatment health promoting lifestyle, and 4) examine the correlation between changes in subscales of health promoting lifestyle. One-group pretest-posttest design was used. Fifty eight college students at T college in T city were studied. They attended a health education, which is composed of 13 sessions(one session per week, 130 minutes per one session). This study was conducted from August 26 to December 2. The instrument used for this study included a survey of general characteristics, self-efficacy, control, perceived health status and health promoting behavior. Analysis of data was done by use of mean, percentage, paired t-test, pearson correlation coefficient and stepwise regression. The results of this study are summarized as follows : 1) The average item score for the health promoting lifestyle was low at 2.301. In the sub-categories, the highest degree of performance was interpersonal support(2.87), following self actualization, nutrition, stress management, exercise, and the lowest degree was health responsibility(1.67). Female students had lowest degree in exercise subscale(1.48). A significant correlation between self-efficacy and control, self-efficacy and perceived health status, self-efficacy and health promoting lifestyle, control and health promoting lifestyle. Self-efficacy was the highest factor predicting health promoting lifestyle of college students(38.31%). 2) No significant difference among total health promoting lifestyle and subcategories of health promoting lifestyle. Self-efficacy was increased after health education than that of before education(T=2.33, P=.023). Control was decreased after education than that of before education(T=-2.03, P=.046). 3) Pretreatment self-efficacy, control, and health status did not predict post-treatment health promoting lifestyle. 4) Pre-to post-treatment changes in self-efficacy predicted post-treatment stress management subscore. 5) Pre-to post-treatment changes in control predicted post-treatment self actualization and exercise subscale. A significant correlation between changes in self-actualization and changes in exercise, changes in self-actualization and changes in nutrition, changes in health responsibility and changes in exercise, changes in exercise and changes in interpersonal support, changes in exercise and changes in stress management, changes in nutrition and changes in interpersonal support, and changes in interpersonal support and changes in stress management.

STATEMENT OF PROBLEM: Titanium-Nickel alloy might be used in various prosthetic restorations since it has a unique property such as super-elasticity and high fatigue resistance. However, little is known about the casting ability of this alloy. PURPOSE: This in vitro study compared the casting accuracy and the porosity made with different investments and various sprue designs to ascertain what casting condition would be better for the fabrication of Ti-Ni cast restorations. MATERIAL AND METHODS: A total of 70 Ti-Ni alloy crowns were made and divided into 7 groups of 10 copings on a metal master die. For measuring the effect of the sprue numbers, two groups with one and two 8-gauge sprues were compared. Moreover, the results of the conventional sprue and the double thickness sprues were compared. Three investments were used; carbon free phosphate bonded investment, titanium investment and gypsum bonded investment. The cast restorations were evaluated at 48 points on the entire circumferential margin with a stereomicroscope measuring in micrometers. Each crown was radiographically examined for casting defects and porosity. Data on casting accuracy were analyzed using two-way and Post hoc Scheffe's comparison to determine whether significant differences existed at the 95% confidence level. Student-Newman-Keuls test were performed to identify significant differences in the number of voids. RESULTS: The double sprueing group and double thickness group had significantly less marginal discrepancy than the single sprueing group (P<.05 and P<.01, respectively). The castings with phosphate bonded investment showed the least marginal discrepancy and the smoothest surface. The castings invested in the gypsum bonded investment had the greatest gaps in margin and the largest failure rate. The double sprueing group and phosphate bonded investment group had significantly smaller void numbers and smaller void size than the other groups. CONCLUSION: Within the limitations of this in vitro study, the casting accuracy of the groups using thicker, double sprue design and the phosphate bonded investment was significantly superior. Moreover, void number and size were less than other groups.

Human parvovirus B19 is a single-strand DNA virus which causes erythema infectlosum, arthralgia, aplastic crisis in patients with red cell defect, chronic anemia in immunocompromised patients, and fetal hydrops in pregnant women . A 16-year-old women was referred to our hospital with pancytopenia and splenomegaly. In peripheral blood, spherocytosis and reitculocytopenia were observed. Many giant pronormoblasts with prominent inclusion bodies and deeply blue cytoplasm were observed but late erythroblasts were not observed in bone marrow smear. Osmotic fragility of patient's red cells was significantly increased. Human parvovirus Bl9 DNA was detected by polymerase chain reaction. Only with supportive therapy, pancytopenia was spontaneously resolved.

PURPOSE: To examine the expression of Connective Tissue Growth Factor (CTGF) in osteosarcoma and to evaluate its role in osteosarcoma invasion and proliferation. MATERIALS AND METHODS: The mRNA expression of CTGF from 23 patient-derived osteosarcoma cell lines was examined, and the role of CTGF in cell invasion and proliferation was examined using siRNA transfection. RESULTS: The over-expression of CTGF mRNA was observed in 17 cell lines (74%). CTGF-specific siRNA transfection into SaOS-2 and MG63 cell lines resulted in efficient knockdown of CTGF expression on Western blot analysis. siRNA transfected cells showed decreased migration on Matrigel invasion assay and decreased cell proliferation on WST-1 assay. CONCLUSION: These results indicated that the CTGF expression may play an important role in osteosarcoma progression, and may be a therapeutic target of osteosarcoma.
