The purpose of this study is to assess individual decisive factors for distribution of medical specialists in Korea. A data set was constructed using several published data sources. including the Korean Medical Association's physician master file as a principal source for physician information. Linear logistic regression analysis was performed to assess the relationship between the location of private specialist clinic for practice with six variables related with individual characteristics: age. sex. location of postgraduate training hospital. location of medical school graduated, size of hospital for training, and specialty. Analysis showed that location of practice. classified into urban and rural areas, was significantly associated with the variables of sex. location of postgraduate training hospital. location of medical school. In addition, significant association was found between the location of practice which was categorized into "near-Seoul area" and others, and sex, location of postgraduate training hospital. and location of medical school. We could conclude that to improve area maldistribution of physicians locations of hospitals for training and medical schools have to have the highest priority in the policymaking.icymaking.

Recently, it has been possible to the alphoid gene, which has X and Y specificity, and determine the sex from human physical evidence using PCR methods. Samples from single sources, PCR method applied to the alphoid gene results in highly sensitive and accurate results even when only 60 pg of the genomic DNA was available for sex determination. Even for samples containing DNA from more than one gender source where the female DNA was present in the amount 10 times than that of the male, sex determination was possible. Therefore, this result suggests that alphoid gene, which has X and Y specificity, could be used effectively for sex determination in case of mixed DNA samples from biological evidence.

"The Act on Medication Treatment of Sexual Impulse of Sex Offenders" known as chemical castration has been effective since July 2011 in Korea. According to the law, monitoring of male sex hormone in urine is enforced to request National Forensic Service more than once a month after injection of medicine designed to reduce sex impulse. We established a rapid and sensitive method for the monitoring of testosterone (T) and epitestosterone (E) in human urine by liquid chromatography with tandem mass spectrometry (LC-MS/MS). Three mL of urine was pretreated by solid-phase extraction for purification and performed enzymatic hydrolysis. The pretreated samples were extracted twice with 2 ml of ethyl acetate and n-hexane (2 : 3). The separation was applied on Thermo Hypersil GOLD C18 column ($1.9{\mu}m$, $100{\times}2.1mm$). A gradient elution of methanol and water of 0.1% formic acid were used as mobile phase and the retention time was less than 10 min. LC-MS/MS system coupled with an electrospray ionization source was performed in multiple reaction monitoring mode. The transitions of the analytes executed as following: m/z $289{\rightarrow}97$, 109 for T and E, m/z $292{\rightarrow}109$ for $T-d_3$ and $E-d_3$ as internal standards. The validation results of the method were satisfactory. The limits of detection were 0.05 ng/ml and the limits of quantification were 0.1 ng/ml. This method was successfully applied to real human urine sample. The developed method will be useful for monitoring T/E ratio in urine of sex offenders.

The purpose of this study was to test the effect of the clothing purchasing situation on the preceived risk and information search behavior. Data were obtained from 369 students who were studying in Semyung University. The results of this study were as follows : 1. Students gave the clothing to their favorites as a gift 1 to 2 times in a year. And they thought self using purchasing was more important than gift giving purchasing. 2. In gift giving purchasing, perceived risks were higher than self using purchasing. But the economic risk was the exception. In that case, students showed more information search behavior except family search source. 3. According to the situation, main and interactive effect of sex and involvement level on perceived risk and information search behavior were significant. In self using purchasing, involvement level had the main effect to the type of information search behavior. But the family search source was the exception Also in gift giving purchasing, they showed the same results. In self using purchasing, main effects of sex and involvement level on perceived risk were significant. Also in gift giving purchasing, they showed the same results, but the socio-psychological risk was the exception.

Vitamin mineral supplement usage by self-prescription is popular behavior among adolescents. This study was conducted to investigate the behaviors of vitamin·mineral supplement usage and the relationship between demographic variables and supplement usage by healthy adolescents. Nine hundred seventy two boys and girls, aged 13-18 years, attending general middle or high schools were chosen from various cities and rural communities in Korea. As a result, vitamin·]mineral supplements were taken by 31.3% of subjects. Users tended to take vitamin·mineral supplements more frequently when they were healthy than when they suffered from disease. The taking period of supplements was different according to school type such as middle or high school(p<.05), sex(p<.001) and residence of subjects(p<.01). The main information source of supplements was newspaper/magazine/TV, and it was affected by sex(p<.05) and residence(p<.01). Vitamin·mineral supplements were generally recommended by their mothers instead of health professionals. The commonly cited taking reason of supplements was affected by sex(p<.01)and socioeconomic status of family(p<.05). The frequently responded effect obtained from supplement use was recovery from fatigue and it was different according to sex(p<.01). The major mentioned reason of not taking vitamin·mineral supplements by non-users was 'I eat a balanced diet'. The most frequently consumed supplements were vitamin C, followed by multi-vitamins supplements, and this pattern was different according to school type(p<.001), sex(p<.01) and residence(p<.05). These findings show that the behaviors of vitamin·mineral supplement usage by subjects are not resonable, and their supplement usage tends to be affected by demographic variables. Therefore, nutritional understanding and education that are intended to form the resonable behaviors toward vitamin·mineral supplement usage of adolescents should be provided with considering the relationship between demographic variables and supplement usage.

The purpose of this study was to examine the relation of stress and perceived social supports to problem behavior during childhood, with particular emphasis on the main and stress-buffering effects of perceived social supports. Such demographic data as parents' educational level, father's job, mother's employment, family income, and child's sex and age were also in chided in the study. Statistical techniques were ANOVA, t-test, and multiple regression. Major findings were that behavior problems of children increased with children's stress and decreased by perceived social supports. Perceived social supports moderated the relation between children's stress and problem behavior. Children's stress and perceived social supports differ by educational level of parents, father's job, and family income. Behavior problems of children were differed by family income, father's educational level and job. Children's stress and behavior problems differed by sex and age in some sub-domains, but perceived social supports did not differ by children's sex and age. Perceived social support from friends was the most influential factor affecting children's problem behavior. Therefore, friends may be considered the most important source of social support that is available for adjustment and for coping with stress during childhood.

Objective: This study was to explore the association between having a usual source of care and adherence to medicines in patient with chronic diseases. Methods: The 2012 Korea Health Panel was used as a data source. We analyzed 4,418 respondents that were diagnosed with chronic diseases and utilized health care services. Non-adherence to medication, a dependent variable, was defined as "not taking the medicines that were prescribed for treating chronic disease" or "not following the direction for medication". Whether having a usual source of care or not was used as a key independent variable, which was defined as having a regular site or a regular doctor for medical test, treatment, and consultation. Sex, age, education level, marital status, income, the type of health insurance, the number of chronic disease and CCI (Charlson Comorbidity Index) were included as covariates in the analysis. We conducted a multivariate logistic regression. Results: Totally, 30 percent of respondents reported to experience non-adherence to medication. Having a usual source of care was significantly associated with lower non-adherence to medication regardless its type, which is a regular doctor (OR=0.61, 95% CI=0.53-0.70) or a regular site (OR=0.67, 95% CI=0.58-0.78). Furthermore, having a usual source of care was associated with both of medication persistence (OR=0.66, 95% CI=0.54-0.81) and compliance (OR=0.65, 95% CI=0.56-0.76). Conclusion: Our results showed the possibility that usual source of care is able to conduct a positive role in improving adherence to medication with better management of chronic disease.
