Objectives : The aim of this study was to verify the intersexuality of Crassostrea gigas and Ruditapes philippinarum in southern coastal waters of Korea. Methods : Specimens of Crassostrea gigas (n=363) were collected from six areas of Tongyeong, Geoje and Yeosu. Ruditapes philippinarum (n=221) was collected from five areas of Yeosu. The sex ratio and intersexuality were determined after observing gonad preparations. Results : The rate of intersexuality in Crassostrea gigas was 16.25%, with females (24.79%; n=30/121) exhibiting a higher rate than males (11.98%; n=29/242). The rate of intersexuality in Ruditapes philippinarum was 24.43%, with females (37.76%; n=37/98) exhibiting a higher rate than males (13.82%; n=17/123). Conclusions : The results of this study suggest that intersexuality is induced by aquatic pollutants such as endocrine disrupting chemicals (EDCs).

National R&D programs play an important role in the development of a country in this age of the knowledge economy. Since many numbers of R&D programs compete for limited resources such as national R&D budget, the R&D program evaluation problem is a challenging decision-making problem faced by decision makers that deal with R&D management. In this sense, DEA(Data Envelopment Analysis) has been regarded as one of the most widely accepted methods to measure the relative efficiency of productivity of R&D programs. DEA is a methodology to measure and to evaluate the relative efficiency of a homogeneous set of decision-making units(DMUs) in a process which uses multiple inputs to produce multiple outputs. However, the sample of the R&D programs could consist of two or more naturally occurring subsets, thus exhibiting clear signs of heterogeneity such as different objectives. In such situations, the fairness of DEA is limited, for the nature of the relative efficiency of a DMU is likely to be influenced by its membership in a particular subset of the sample. In this study, we propose a methodology AI-DEA(attainment index DEA) allowing for reflecting decision maker's subjective judgement on difference among different subsets of R&D programs which have heterogeneous objectives. This methodology combines AHP and Delphi in order to decide the attainmnet index of each DMU for each outputs, and apply them to DEA model. We illustrate the proposed approach with a pilot evaluation of 13 programs involving 6 different subsets of Korean National R&D programs and compares the results of the original DEA model and AI-DEA model.

It is not common in rehabilitation situation to encounter patients exhibiting paralysis or other disabilities which have no apparent organic basis. Even without organic causes for their signs and symptoms these patients often require comprehensive treatment and management. Patients with conversion disorder often pose particular difficulties because of diagnostic confusion and the lack of therapeutic strategies for rehabilitation management. We feel that systematic functional rehabilitation is helpful in resolving symptom and recovering normal function in the patient suffering from conversion disorder since it provides motivation and reduces reinforcements which contribute to sustained disabled state. This report describes the patient with hysterical motor paralysis who is successfully treated with structured physical therapy. The objectives of this report are to provide therapeutic guidelines for physical therapy and to emphasize the role of physical therapist in the assessment and treatment of hysterical paralysis.

Multi-span steel-concrete composite (SCC) bridges are very sensitive to earthquake loading. Extensive damage may occur not only in the substructures (piers), which are expected to yield, but also in the other components (e.g., deck, abutments) involved in carrying the seismic loads. Current seismic codes allow the design of regular bridges by means of linear elastic analysis based on inelastic design spectra. In bridges with superstructure transverse motion restrained at the abutments, a dual load path behavior is observed. The sequential yielding of the piers can lead to a substantial change in the stiffness distribution. Thus, force distributions and displacement demand can significantly differ from linear elastic analysis predictions. The objectives of this study are assessing the influence of piers-deck stiffness ratio and of soil-structure interaction effects on the seismic behavior of continuous SCC bridges with dual load path, and evaluating the suitability of linear elastic analysis in predicting the actual seismic behavior of these bridges. Parametric analysis results are presented and discussed for a common bridge typology. The response dependence on the parameters is studied by nonlinear multi-record incremental dynamic analysis (IDA). Comparisons are made with linear time history analysis results. The results presented suggest that simplified linear elastic analysis based on inelastic design spectra could produce very inaccurate estimates of the structural behavior of SCC bridges with dual load path.

Objectives : The education of dental hygienists on emergency care has been implemented as a part of curriculum at school, the contents and practice are inadequately and unsystematically conducted. The purpose of the study was to examine the perception and use of emergency care in dental hygienists in various emergency situations and emergency medical equipment. Methods : The subject of this study was 64 dental hygienists dental hygienists in Chungchenongnam-Do. The data were collected through a self-administered questionnaire from November, 17 to 24, 2011. Results : Only 3.1% of dental hygienists answered "I know very well", exhibiting relatively low level of recognition. Moreover, 15.6% of respondents answered "I know quite well", 53.2% answered "I know somewhat well", and 28.1% answered "I do not know well". In terms of the operation of defibrillator, 9.4% of dental hygienists answered "yes" and 90.6% answered "no". Regarding performing CPR, 15.6% of respondents answered "I can perform" while 84.4% answered "I can not perform". Conclusions : Despite the education on emergency medicine, dental hygienists working in dental clinics are found to be not well aware of proper perception of emergency care and the utilization of emergency medical equipment. Therefore, appropriate refresh educational framework and development and application of programs are thought to be essential for dental hygienists to adequately and swiftly respond to emergency situations by full recognition of the importance of emergency care.

Objectives: To identify factors affecting the health of male professional soldiers. Methods: Cross-sectional questionnaire data was collected from a randomly stratified sample population of 763 officers and sergeants who were employed in 34 units in the Korean military. Data were statistically analyzed using Chi-square test and multiple logistic regression analysis. Results: Work environment and personal health behavior were influential factors, which were differentiated by recent disease history including cardiovascular disease and self-rated health status. Sergeants in special forces/units or engaged in front-line military activities, and soldiers who were current smokers and heavy drinkers were more likely to have been diagnosed with a disease in the preceding three months. Those who were older, obese, and heavy drinkers were more likely to have cardiovascular disease than those who were less obese and more physical active. Soldiers exhibiting signs of extreme stress were more likely to poorly self-rate their health status. Conclusion: Health behaviors and characteristics of work environment significantly influence the health status among Korean professional soldiers. Health promotion strategies are needed to change individual heath behaviors such as smoking, alcohol consumption, and work stress. A healthier working environment should also be promoted.

Objectives: Recent research indicates a potential association between workplace violence and an increased risk of cardiovascular disease (CVD) in the working-age population. However, the relevant evidence in the United States is sparse. Thus, this study was conducted to explore the possible relationship between workplace violence and CVD among United States workers. Methods: We utilized cross-sectional data from the 2015 National Health Interview Survey, which included a representative sample of 18 380 workers, to investigate the associations between workplace violence and the prevalence of CVD using logistic regression. Workplace violence was determined based on self-reported threats, bullying, or harassment at work over the past 12 months, supplemented with additional information regarding frequency. CVD included all forms of heart disease and stroke. Results: A total of 1334 workers reported experiences of workplace violence, and 1336 workers were diagnosed with CVD. After adjustment for covariates, participants who reported any instance of workplace violence had significantly higher odds of having CVD (odds ratio [OR], 1.76; 95% confidence interval [CI], 1.35 to 2.30) than those who reported no such violence. Furthermore, the highest odds of CVD (OR, 1.80; 95% CI, 1.23 to 2.63) were observed among those frequently exposed to workplace violence. Even occasional exposure to workplace violence was associated with 74% excess odds of CVD. Conclusions: Our study indicates an association between workplace violence and CVD in United States workers, exhibiting a dose-response pattern.

Objectives: This study aimed to analyze research literature, created over the past 10 years, on occupational stress among domestic dental hygienists and identify the major factors affecting occupational stress. Methods: Of the 192 articles found through literature searches, 26 were selected for the analysis after reviewing titles, abstracts, and full texts. General characteristics of each study, measurement tools employed, and data related to pertinent factors were systematically analyzed. Results: Seven instruments were utilized to measure job stress. Among the variables exhibiting positive correlation with occupational stress, turnover intention was the most prevalent, while variables showing negative correlation were predominantly associated with job satisfaction. Factors influencing occupational stress included emotional labor, workload, organizational social capital, and experiencing verbal abuse. Conclusions: With regard to the most influential factors, "emotional labor" and "turnover intention" had the greatest impacts on job stress and occupational stress, respectively. Based on the findings of this study, follow-up research needs to be conducted to suggest ways to prevent, manage, and reduce occupational stress among dental hygienists

Objectives : Periodontal disease is a serious oral disease that frequently occurs among adults. The objective of this study is to provide necessary data for the development of an oral health care program that can effectively manage periodontal disease and subsequently maintain and enhance oral health. Methods : Data was collected from patients of a dental clinic in Daejeon, Korea from 1 July to 25 August 2009. A thesis submitted to the Committee of Graduate School of Public Health & Biotechnology Chungnam National University in partial fulfillment of the requirements for the degree of Master of Public Health conferred in February, 2010. Results : 68% of the patients were aware of periodontal disease, with older patients exhibiting better awareness. 48.0% replied that their periodontal health is good in general, with older patients inclined to say that their periodontal health was poor. 70.5% cited bad brushing habit or skipping the act of tooth brushing as the cause of periodontal disease, while 63.5% reported brushing their teeth an average of 3 times a day. 56.5% said that they brush their teeth correctly, and 63.5% told that they brush their teeth up and down, and left to right and 70.0% replied that they would attend an educational program for the prevention of periodontal disease, with older patients shown to more likely attend such a program. Conclusion : a program that can motivate people to become aware of the importance of oral health care should be developed and implemented. Such a program should include the dissemination of correct and accurate oral health care information and measures for educating people about the importance of prevention.
