Purpose: The aim of this study was to investigate the effects of occupational stress and coping styles on burnout of clinical nurses. Methods: The participants in this study were 397 nurses, working at the hospitals in Seoul, Gangwon, and Gyongbuk provinces. Data were collected using a structured questionnaire from November, 2009 to January, 2010. The SPSS WIN 13.0 version program was used for data analysis. Results: The most significant predictors of burnout were positive reappraisal and work load. Work load, resource inadequacy, role ambiguity, and indifference coping style positively correlated with burnout. Positive reappraisal and problem-focused coping styles negatively correlated with burnout. Conclusion: The study results indicate that it is important to reduce work load, resource inadequacy, and role ambiguity in nurses and to strengthen their positive reappraisal and problem-focused coping styles to prevent burnout. This could be achieved with job redesign, modification of shift work systems, and by offering burnout prevention program.

Purpose: This study sought to investigate the relationship between smoking, drinking and the mental health of adolescents. Method: The study subjects included 1,092 randomly sampled third-year middle and high school students from N-City and the L-Kun area in Chonbuk Province. The data were collected using an anonymous questionnaire developed by the Ministry of Health and Welfare(2005). The data were analyzed using the SPSSWIN 15.0 Program. Result: The smoking rate in the adolescents was 10.1%, and the drinking rate was 43.2%. The stress recognition rate in normal daily life was 45.5%, the frequency of depressive symptoms was 33.2% and 40.0% of the subjects reported that they wanted to die at some point within the past year. The rate of stress recognition, depressive symptom experience, suicidal planning and attempt in smokers and drinkers was higher than that in non-smokers and non-drinkers (p<.05). Especially, the frequency of suicidal thoughts was higher in the drinkers than in the non-drinkers (p<.05). Conclusion: The smoking and drinking status of the adolescents was correlated with their mental health a sit relates to stress, depression and suicide. Therefore, an effective program for the prohibition of cigarette smoking and alcohol consumption is needed in order to prevent smoking and alcohol consumption in adolescents and improve their mental health status.

In this study, samples from the site where there occurred unbalanced current when cable routing were analyzed, and the simulation program for electric power system analysis, PSCAD/EMTDC, was used to calculate the current unbalance on cable routing. Based on electromagnetic finite element analysis(FEA), electromagnetic parameters enabled the interlocking with COMSOL for the calculation of allowable current ampacity and magnetic filed distribution. This then led to modeling unbalanced current between common modes using the unbalanced current analysis program, thereby comparing and discussing the results from both. The analyzed model is a common mode 2 parallel circuit, which is a basic model for cable routing, and by arranging cables in various ways, the arrangement with the least current unbalance was suggested, which would, in the future, prevent earth faults and extend life for the whole cable.

Encryption technology is to hide information in a cyberspace built using a computer and to prevent third parties from changing it. If a malicious user accesses unauthorized device or application services on the Internet of objects, it may be exposed to various security threats such as data leakage, denial of service, and privacy violation. One way to deal with these security threats is to encrypt and deliver the data generated by a user. Encrypting data must be referred to a technique of changing data using a complicated algorithm so that no one else knows the content except for those with special knowledge. As computers process computations that can be done at a very high speed, current cryptographic techniques are vulnerable to future computer performance improvements. We designed and implemented a new encryption program that combines ancient and modern cryptography so that the user never knows about data management, and transmission. The significance of this paper is that it is the safest method to combine various kinds of encryption methods to secure the weaknesses of the used cryptographic algorithms.

The purpose of this single subject care study was to evaluate the effectiveness of a functional electrical stimulation(FES) treatment program designed to prevent glenohumeral pint stretching and subsequent subluxation and shoulder pain in hemiplegic patients. The subject was a 43-year-old male who had left side hemiparesis with shoulder pain and subluxation on affected side. He received conventional physical therapy and additional FES therapy where two flaccid shoulder muscles, supraspinatus and posterior deltoid. were induced to contract repetitively up to 20 minutes for 2 weeks. As a result. the patient showed improvements in hemiplegic arm function, reduction in subluxation(as indicated by Jig test) and range of motion(SLROM). But it was difficult to generalize. We concluded that the FES program was effective in reducing the severity of shoulder subluxation and pain. Further study must be evaluated its statistical significance.

Food compost, having a higher organic contents than soil, could be an alternative material to prevent the proliferation of heavy metals contamination in soil. In this study we used a convection-dispersion local equilibrium sorption model(CDE) and a two-site non-equilibrium sorption model to find the effects on the adsorption and transportation of Pb by mixing food compost with soil and we also tried to find the effect of velocity and concentration of the injected solution on the characteristics of Pb. We measured Pb concentrations in injection-liquid and in effluent, and then applied them to CXTFIT program. As a result of column experiments, some parameters(D, R, ${\beta}$, ${\omega}$) used in two-site non-equilibrium adsorption model were obtained. Characteristics of Pb adsorption and transport were analyzed using the parameters(D, R, ${\beta}$, ${\omega}$) obtained from the CXTFIT program, We could know that mixed soil with food compost showed a higher adsorption capacity from the retardation factor(R) calculated from the breakthrough curve(BTCs) of Pb. Rs of soil and mixed soil are 20.45, 37.45 respectively, indicating that the adsorption and the transportation characteristics could be accessed quantitatively by using of two-site non-equilibrium adsorption model.

Purpose: The purpose of this study was to identify the factors influencing intention of migration by Korean hospital nurses. Methods: Using cross sectional correlational design, data were collected from 512 nurses working in 7 hospitals ranging in size from 300 to 900 beds in D city and K province of Korea. Data were analyzed by descriptive statistics, chi-square, and multiple hierarchical regression using the SPSS program. Results: There were significant differences in intention of migration by age, educational background, marital status, work experience, and yearly incomes. Although there was high intention of migration of the subjects, the level of preparation for migration was relatively low. The variables that were independently associated with intention of migration were graduates of RN-BSN program, personal factors of subjects, and environmental factors. Those who had lower perception on nursing images and work condition had significantly higher intention of migration than those who had higher perception. Full model accounted for 37.3% of the variance in intention of migration. Conclusion: To prevent brain drain of competent nurses in Korea, appropriate strategies to enhance work condition should be developed and the effect of migration of nurses should be investigated in further studies.
