The purpose of this study was to find out the relationships between emotional labour and depressive symptoms among nurses in university hospitals. Subjects were 514 nurses working at three university hospitals in Daejeon City, and the survey was a structured self- administered questionnaire based from April 1 until May 31 2012. As a results, the level of depressive symptoms by the subjects emotional labour level was significantly higher in the group with higher total average points of the emotional labour than the lower group, As for the correlation between the level of depressive symptoms and emotional labour factors, the depressive symptoms points showed significant positive correlation with the total points of the emotional labour. As a result of hierarchical multiple regression, age, leisure time, coffee consumption, subjective health status, physical burden of work, sense of satisfaction at work, fit to the job and emotional labour were selected as significant variables and related variables effecting the level of depressive symptoms. These variables' descriptive power was 39.4%, especially, it can be seen that 11.0% descriptive power increased by putting the emotional labor variables. The results above imply that there is significant relation between emotional labor and depressive symptoms and various variables such as socio-demographic characteristics, health-related behavior factors and job-related factors. Also, it can be seen that the emotional labour and depressive symptoms showed significant positive correlation. Therefore, the development and implementation of a program to control emotional labor appropriately should be required for lowering the level of depressive symptoms.

We need various methods to develop MMORPG that is game genre which many users use among various game genre using Internet. Specially, to heighten efficiency of distributing work, Object-oriented language such as C++ is used and we need design techniques that can take advantage of enough object-oriented concept when making large-scale game. There is various pattern that can apply in software breakup design in GoF's design pattern for these design techniques. If you apply Observer pattern to Party System Design for forming community between game users, you can easily add new class and maintain system later. Party Play is one of the important system that is used to form game users' community in MMORPG games. The main point that must be considered in Party-Play-System is to divide evenly experience value and acquisition that is got by Party-Play among users according to each user's level. To implement Party Play System that consider maintenance of system, in this paper, we propose a method using GoF's Observer-Pattern, showing you that proposed method which has advantage to dynamic memory allocation and to virtual method call can be used usefully to change object to real time at program run and to add new class and to maintain system new.

Objective : This study was undertaken to analysis gamma knife radiosurgery(GKR) effect for trigeminal neuralgia after long term follow-up. Methods : There were 11 trigeminal neuralgia patients. The authors irradiated 67-85 Gy maximally to the nerve root entry zone(NREZ) using single 4mm collimator, just 1-6mm lateral side from the junction of the trigeminal nerve and pons. For the first 3 cases, we targeted the junction between the nerve and the pons. In theses cases, the pons was irradiated 56 or 60 gray in the surface. In the later 8 cases, the isocenter is positioned more distal side so that the brain stem surface would receive less than the 20% isodose. Results : The average follow-up duration was 25 months(13-50 months). Pain relief was noticed within a week to 5 months. In 3 patients, pain was relieved completely and in other 3 patients, mark improvement was achieved(80-90%). Remaining 4 patients showed significant improvement(30-50%). There was recurrence in only one case and she complained with similar intensity of pain at the last follow-up. There was no significant complication related to GKR. Conclusion : GKR is considered effective for trigeminal neuralgia based on the long term follow-up evaluation, but more clinical experience is needed to evaluate the efficacy of GKR for trigeminal neuralgia as a primary treatment modality.

We present our experience of combining, in a realistic setting, a static analyzer with a statistical analysis. This combination is in order to reduce the inevitable false alarms from a domain-unaware static analyzer. Our analyzer named Airac(Array Index Range Analyzer for C) collects all the true buffer-overrun points in ANSI C programs. The soundness is maintained, and the analysis' cost-accuracy improvement is achieved by techniques that static analysis community has long accumulated. For still inevitable false alarms (e.g. Airac raised 970 buffer-overrun alarms in commercial C programs of 5.3 million lines and 737 among the 970 alarms were false), which are always apt for particular C programs, we use a statistical post analysis. The statistical analysis, given the analysis results (alarms), sifts out probable false alarms and prioritizes true alarms. It estimates the probability of each alarm being true. The probabilities are used in two ways: 1) only the alarms that have true-alarm probabilities higher than a threshold are reported to the user; 2) the alarms are sorted by the probability before reporting, so that the user can check highly probable errors first. In our experiments with Linux kernel sources, if we set the risk of missing true error is about 3 times greater than false alarming, 74.83% of false alarms could be filtered; only 15.17% of false alarms were mixed up until the user observes 50% of the true alarms.

This study examined the fatigue and its association with job stress among male workers engaged in small-scale manufacturing industries. The study subjects were 553 male workers under 50 members of manufacturing industries. The study survey was a structured questionnaire of the Korean Occupational Stress Scale (KOSS) and Multidimensional Fatigue Scale (MFS) during April, 2015. The data were analyzed using the SPSS ver 21.0 program. The results showed that the high risk fatigue group was significantly higher in the high risk group of job stress than in the normal group of job stress. Fatigue was positively correlated with job stress. The odds ratio of the high risk fatigue group were increased significantly in the high risk group of job stress than in the normal group of job stress. The factors of influence with explanatory powers of 27.7% on fatigue included age, marital status, educational level, subject health status, sleeping time, drinking coffee, job tenure, shift work, visiting out-patient department, sense of satisfaction in job life, and job stress. Fatigue was associated with the sociodemographic characteristics, health behavior related characteristics, job-related characteristics, and job stress.

Objectives: This study examined the characteristics and related factors by comparing the lifestyles and health behaviors between Korean Seventh-day Adventists and the general population of Korea. Methods: A survey was conducted of 878 people more than 20-years-old Korean Seventh-day Adventists who live in the metropolitan area and 3,000 people more than 20-years-old who live in the metropolitan area in 4th (2nd year) National Health and Nutrition Survey. A comparison of health behaviors related to health screenings, smoking, drinking, physical activity, subjective stress, weight management, and oral health was analyzed using a chi-square test. Logistic regression analysis was used to identify the contributing factor to the health behavior. Results: Health screening rates among Korean Seventh-day Adventists were higher than the general population (p<0.001), but Korean Seventh-day Adventists showed lower rates of health screening in the 20-30 ages. Lifetime smoking experience rates and current smoking rates were significantly lower in the Korean Seventh-day Adventists than in the general population (p<0.001). The success rate of smoking cessation among ex-smokers of Korean Seventh-day Adventists were very high. In terms of the drinking rate, Korean Seventh-day Adventists were significantly lower than the general population (p<0.001). The drinking rate of men was higher than women (p<0.001). Moderate physical activity of men were higher than women in Korean Seventh-day Adventists (p<0.001). Conclusion: The lifestyles and health behaviors of Korean Seventh-day Adventists, such as tobacco smoking and alcoholic drinking, were eminently healthier than the general population. Nevertheless, further well-organized studies will be needed.

The purpose of this study was to define the relationship between job stress contents and smoking habits of manufacturing male workers. The 872 male workers were observed the general characteristics, smoking habits and job stress contents from the JCQ, during the period from February 1st to April 30st, 2012, using the self-administered questionnaires. As a results, the smoking rate of study subjects was 53.0%, and in terms of smoking status by general characteristics, the smoking group was higher in the group of age, job position and job career than their respective counterparts. In terms of smoking status by job stress contents, the smoking group was higher in the group of job demand and supervisor support than their respective counterparts. Based on the results of logistic regression adjusted age, job position and job career, the odds ratio of smoking was significantly increase in the high group of job demand than that of low group, but it was significantly decrease in the low group of supervisor support than that of high group. Above results suggested that the smoking related with the job demand and the supervisor support among the job stress contents.

The purpose of this study was to investigate whether medial gastrocnemius ultrasound imaging of the Delayed Onset Muscle Soreness (DOMS) has the possibilities as a measurement method. This study was conducted from April 21th 2011 to April 30th 2011. Thirty-five healthy subjects were included based on the absence of regular physical activity, and no history of recent trauma, musculoskeletal pathology, cardiovascular disease or drug intake. All subjects induced DOMS through climbing for 5 hours and we measured the visual analogue scale (VAS), creatine kinase (CK) and maximal voluntary isometric contraction (MVlC) of ankle plantar flexor prior to DOMS and at 24, 48 and 72 hours post DOMS and these measurements were compared with pennation angle of medial gastrocnemius measured by ultrasound imaging. Results of this study were as following. VAS, CK, and MVIC of ankle plantar flexor were found significant difference related measurement period (p<0.05) and pennation angle of medial gastrocnemius were found significant difference related measurement period (p<0.05). Furthermore, we confirmed that the flow of change between variables related measurment period was consistent. Through this study, we think that measuring the changes in pennation angle of medial gastrocnemius over time using ultrasound imaging will be able to be used as a new method measuring DOMS.
