Objective: To investigate adverse pregnancy outcomes in non-obese women with polycystic ovary syndrome (PCOS) compared with obese-PCOS and control groups. Methods: Women with PCOS who underwent assisted reproductive technology (ART) from August, 2003 to December, 2007, were considered. A total of 336 women with PCOS were included in the study group and 1,003 infertile women who had tubal factor as an indication for ART were collected as controls. They were divided into four groups: a non-obese PCOS group, obese-PCOS group, non-obese tubal factor group, and obese tubal factor group, with obesity defined by a body mass index over 25 kg/$m^2$, and reviewed focusing on the basal characteristics, ART outcomes, and adverse pregnancy outcomes. Results: There was no difference among the groups' the clinical pregnancy rate or live birth rate. Regarding adverse pregnancy outcomes, the miscarriage rate, multiple pregnancy rate, and prevalence of preterm delivery and pregnancy induced hypertension were not different among the four groups. The incidence of small for gestational age infant was higher in the PCOS groups than the tubal factor groups ($p$ <0.02). On the other hand, the morbidity of gestational diabetes mellitus (GDM) was not high in the non-obese PCOS group but was in the obese groups. And in the obese PCOS group, the newborns were heavier than in the other groups ($p$ <0.02). Conclusion: Non-obese PCOS presents many differences compared with obese PCOS, not only in the IVF-parameters but also in the morbidity of adverse pregnancy outcomes, especially in GDM and fetal macrosomia.

Twitter has been continuously growing since October, 2006. Especially, not only the users and the number of messages have been increasing but also a new concept in social networking called 'micro blogging' has diffused. Within Korea, service such as 'me2day' has already been introduced and the improvement of internet accessibility within mobile devices is expected to expand the 'micro blogs'. In this point, this research is executed to study the new medium, 'micro blog'. To do so, we collected and analyzed Twitter logs of Korean users. Especially, we were curious about the extreme heavy users using Twitter, despite of the linguistic and cultural barrier of the foreign service. Who they are, why and how they use the 'micro blog'. First, we reviewed the general aspect of followers and messages by collecting a certain number of random samples. Using the Lorenz curve we found out that there was the imbalance within the users and based on this phenomenon we deducted an extreme heavy user group. In order to perform further analysis, log analysis was performed on the extreme heavy users. As the result, the users used multiple mobile and desktop 'Twitter' clients. The usage pattern was similar to that of internet usage time but was used during their "micro" time. The users using 'Twitter' not only to spread messages about important information, special events and emotions, but also as a habitual 'chatting tool' to express ordinary personal chats similar to SMS and IM services. In this research, it is proved that 68% of the total messages were ordinary personal chats. Also, with 24% of the total messages were retweets, we were able to find out that virtually connected 'people' and 'relationships' acted as the dominant trigger of their articulation.

In this study, we investigated the relationship between friendship level within a hospital organization and job satisfaction, organizational commitment and job stress. Focusing on the hierarchy and occupation of a hospital, different from previous introductory studies. As a study tool, structured questionnaire were devised and used. The subjects were nurses, administrators and medical technicians who worked at 17 tertiary hospitals in Seoul and Kyongin area. To analyze the data, we conducted frequency analysis, t-test, one-way ANOVA, two-way ANOVA and multiple regression analysis.The main results of our study can be summarized as followings:Firstly, seen from the viewpoint of social demographic characteristics, on the whole friendship level with fellows is the highest, and then that with subordinates and that with bosses the lowest. Secondly, the friendship level with bosses, subordinates and fellows had a significant relationship with job satisfaction, organizational commitment and job stress, though there were some differences among them. In case of junior managers, the friendship level with fellows had a significant relationship with job satisfaction and organizational commitment; in case of middle managers, the friendship level with fellows had significant relationship with job satisfaction. We found that the friendship level with the bosses had a deeper relationship with job satisfaction, organizational commitment and job stress as we went down the hierarchy. Thirdly, analyzing the differences between occupation, administrators and medical technicians had relatively higher significant relationship with the friendship level with bosses than nurses in job satisfaction, organizational commitment and job stress. High friendship level with the bosses influenced job satisfaction significantly for the nurse; yet, in case of administrators and medical technicians, the friendship level with bosses influenced all of job satisfaction, organizational commitment and job stress. Based on our study, we recommend facilitating friendly relationship between the bosses and the subordinates in order to enhance job satisfaction, organizational commitment and job related stress reduction.

Purpose : The purpose of this study was to analyze the prehospital care report prepared by EMS squads of 119 center in Gyeonggi area and to identify the status of prehospital care activities, problems and improvement possibilities of the emergency care. Method : Five hundred copies of prehospital care report prepared by EMS squads in thirty-eight 119 centers under 18 fire stations in Gyeonggi area from March to April in 2008 were randomly chosen for the analysis. Data abstracted according to the purpose of the study were input and the analysis of prehospital care activities were performed using SPSS-WIN(ver. 16) statistics package. Results : 1. Total 500 cases of prehospital emergency care activities were reviewed. By sex, females were 219 (43.8%) and males were 281 (56.2%). The places of reporting were home (57.8%). According to the type of emergency, 281 cases (56.2%) were caused by disease and 291 (43.8%) were from other causes such as traffic accidents or incidental injuries. 2 The average time needed for the 119 EMS squad to arrive at the scene after being reported was 7.29 minutes. The time used at the scene for the emergency care was 7.3 minutes in average and the time to arrive at the hospital was 25.4 minutes in average. 3. In patient evaluation, in 68% of the cases more than two vital signs were measured at one time and emergency patients were 31%, and non-emergency patients were 69%. 4. In one EMS activity, average 2.15 cases of emergency care were provided to a patient. The cases where two kinds of emergency care were given were 14.4%, which is the most frequent cases. When reviewing the details of the emergency cares given to the patient including multiple cares, trivial cards (taking it easy and giving comfort) were the most frequent one as 40.6% and the medical direction of the doctor was given in only one case out of 500 cases. 5. In patient evaluation and emergency care, vital signs were provided to emergency patients at significantly higher rate comparing to the non-emergency patients. The number of emergency care performance was significantly higher in emergency cases. In emergency dispatch, the cases that EMT (1st class) was on board was 86.2%. When comparing the cases when the 1st class EMT was on board and otherwise, the cases with the presence of 1st class EMT showed more vital signs were detected but there was no significant difference in the number of emergency cares provided. Conclusion : It seemed that the on-scene emergency care did not satisfy the expectations. So it is necessary to enforce the cooperation between the elements, the qualifications of the 119 EMS squads and to improve the prehospital working environment in order to provide the better medical service at any time.

The purpose of this study was to analyze the effect of environmental perception in neighborhood parks on user's recognition of health improvement. This study used objective field survey data and subjective user survey data at 8 neighborhood parks in Changwon City. According to the results, the perceptions of distance and street environment from home to park were evaluated highly but the perception of water spaces and various attractions within the parks were rated lowly in most of parks. As a result of factor analysis, 23 environmental perception variables were classified into 6 factors such as scenery, comfort, accessibility, activity, convenience and amenity. For the result of regression analysis between environmental perceptions and user's recognition of health improvement based on 6 factors, the recognition of physical health improvement was significantly influenced from environmental perception factors in 4 parks among 8 parks. 'Accessibility' and 'activity' were analyzed as the meaningful factors in 3 parks. Also, recognition of mental health improvement was significantly influenced from environmental perception factors in 5 parks among 8 parks and especially 'accessibility' was showed as the significant factor in 4 parks. The findings from this study can contribute to improve the physical environments of the present parks and can be a basic data for new park development.

Purpose - There have been local government systems since June 1955. Many local governments have made use of festivals for regional public relations and the achievement of competitiveness. This study analyzes effective components of local festivals. There has been extensive research in relation to variables such as participation motivation, satisfaction level, recall intention, royalty, and recommend purpose. However, as a variable factor, attachment to the participation motivation of a festival has been overlooked along with support level to a festival. This study has added new variables named "attachment to local society" and "support level," which are dependent variables. We will study the relationship of these two variables. Research design, data, and methodology - This study has devised a cause-and-effect relationship model, which deduces that local residents' participation motivation for the festival will have positive influence on the festival support level and satisfaction level. We circulated questionnaires to local residents to get the data required to prove the hypothesis. To analysis the data, we used SPSS 21.0, and accomplished basic analysis through the analysis of frequency as well as descriptive statistical analysis. Further, we verified our measurement tools through reliability analysis, and examined the research hypothesis through multiple regression analysis. Results - With regard to the festival satisfaction level, the variables of local society attachment, festival attraction, escaping from the daily life, and family harmony have influence upon a positive effect (+) in this order. Among them, the variable of local society attachment has the greatest influence. However, in respect of support level for the festival, only the variables of local society attachment and escaping from the daily life have a valid influence on the positive effect (+), and local society attachment has relatively greater influence. In addition, not only does the festival satisfaction level affect the support level for the festival in terms of positive effect, the influence is also far-reaching, which verifies the mediating effect. Conclusions - The result shows that the local residents' satisfaction level with the Yudalsan Mountain Spring Flower Festival is comparatively high, which is due to the local society attachment. It also shows that it is difficult to create support without local residents' attachment with their area. Consequently, this study insists that the Yudalsan Mountain Spring Flower Festival should exceed its limitation as just a village-level party, in order to become a remarkable and outstanding festival, and suggests three operational implications: macro-environmental development, task environment development, and internal operational environmental development. From the macro-environmental perspective, the constant development of local culture and local business is proposed. In the task environment perspective, a new functional development for the festival is proposed. From the internal operational environmental perspective, improvements in festival operation methods are proposed. If these weak points are addressed and resolved through a more detailed approach, it will be very helpful for local government systems to operate the festival.

This study focuses on adolescent prosocial behavior as one of the necessary elements for youth to grow as a healthy member of the society. The purpose of this study is to examine the effects of peer group on adolescent prosocial behavior by comparing the peer influence model and the individual characteristics model. For the study, we conducted hierarchical multiple regression analyses using the data from the Korean Youth General Survey 2008, administered by the Ministry of Health and Welfare. Results show that friends' prosocial behavior had a positive impact, but friends' antisocial behavior had a negative impact on adolescent prosocial behavior. When individual characteristics including self-esteem and empathy were analyzed simultaneously, empathy, self-esteem, friends' prosocial behavior, and friends' antisocial behavior were found to be statistically significant. The strength of association between individual characteristics and adolescent prosocial behavior was greater than that of friends' behaviors. Also, significant moderating effects of individual characteristics on the relationships between adolescent prosocial behavior and friends' behaviors were found. For example, the positive effect of friends' prosocial behavior on adolescent prosocial behavior increased as adolescent's level of self-esteem increased. On the other hand, the negative effect of friends' antisocial behavior on adolescent prosocial behavior decreased as adolescent's level of empathy increased. Based on the findings, both the peer influence model and the individual characteristics model were considered valid in explaining prosocial behavior of Korean adolescents. Finally, implications of this study for positive youth development were discussed.

The purpose of this study was to examine the relationships among child abuse, depression, and smartphone addiction by gender. Data were gathered though questionnaires surveying 1,601 adolescents living in the Seoul and Kyeonggi areas. The results of t-tests and multiple regression analyses using structural equation modeling are as follow. First, approximately 40 percent of adolescents reported having experienced child abuse in the past year. Second, 24.5 percent of adolescents were found to be at risk of smartphone addiction. Third, child abuse was associated with depression and smartphone addiction among adolescents, and depression was found to have a mediating effect on the relationship between child abuse and smartphone addiction. Lastly, gender differences were also found: for male students, child abuse was directly related to smartphone addiction; for female adolescents, depression was found to mediate the relationship between child abuse and smartphone addiction. The results suggest different intervention strategies according to gender and a necessity of intervention to prevent child depression and smartphone addiction. The implications for social work practice were also discussed.
