Objectives: This study aims to classify the latent profiles in the exposure to hazard factors of salaried employees and test the determinants. Methods: Latent profile analysis(LPA) was conducted using data from the fifth Korean Working Conditions Survey(KWCS). 30,050 of salaried employees were the subjects of this study. After classifying the employees, multinomial logistic regression was used to test the determinants. Results: Salaried employees were classified with three latent profiles based on the exposure to the hazard factors. Employees included in class 1(32.8%) tend to experience low level of physical hazard factors, moderate level of psychological hazard factors, and high level of office work hazard factors. Employees included in class 2(61.8%) tend to be exposed to the moderate to high level of physical hazard factors, moderate to low level of psychological hazard factors, and low level of office work hazard factors. Employees included in class 3(5.4%) tend to experience high level of psychological and physical hazard factors, and moderate level of office work hazard factors. After classification, the demographic, health-, and employment-related variables were tested. Conclusions: This study clarified the features of each class, and proved that employees in class 3 are quite hazardous in that they are exposed to physical and psychological hazard factors much more frequently than other employees. Thus, this study can be used in predicting the high-risk employees and taking preemptive measures for preventing industrial accidents.

Purpose - The purpose of this study is to identify the influence relationship between positive psychological capital, job satisfaction, and organizational commitment of tourism guides, and to provide implications through empirical research to increase the capabilities of tourism guides that are a factor in the performance of planned travel products Design/methodology/approach - This study conducted an empirical survey using the google online questionnaire. It was directly surveyed, distributed, and collected from workers who were or were performing tourism guide duties in Asia and Europe, and 203 questionnaires were used for analysis. The empirical survey was conducted in a self-written manner through a simple random sampling method, and the statistical package was conducted with frequency analysis, factor analysis, multiple regression analysis, and correlation analysis using the spss 21.0 program. Findings - First, among the positive psychological capital factors, two factors, hope and optimism, have a significant positive (+) effect on job satisfaction. Second, among the positive psychological capital factors, two factors, self-efficacy and optimism, have a significant positive (+) effect on organizational commitment. Third, job satisfaction has a significant positive (+) effect on organizational commitment Research implications or Originality - The implications of this study are that the research results have had a positive (+) effect on the variables of positive psychological capital, job satisfaction, and organizational commitment of tourism guides, and have laid the foundation for academic research on research topics.

Recently, Live-Virtual-Constructive (L-V-C) integrate training system has proposed as a solution for the problems such as limitation of training areas, increase of mission complexity, rise in oil prices. In order to integrate each training system into the one effectively, we should solve the issue about stress of pilots by the environmental differences between Live and Virtual simulation which could be occurred when each system is connected together. Although it was already examined in previous study that the psychological effects on pilots was occurred by the environmental differences between actual and simulated flights, the study did not include what the causal factors affecting psychological effects are. The aim of this study is to examine which environmental factors that cause pilots' psychological effects. This study analyzed the biochemical stress hormone, cortisol to measure the pilots' psychological effects and cortisol was measured using Enzyme-linked immunoassay (EIA). A total of 40 pilots participated in the experiment to compare the differences in pilots' cortisol response among live simulation, virtual simulation, and the virtual simulation applying three environmental factors (gravity force, noise, and equipment) respectively. As a result, there were significant differences in cortisol level when applied the gravity force and equipment factors to the virtual simulation, while there was no significant difference in the case of the noise factor. The results from this study can be used as a basis for the future research on how to make L-V system by providing minimum linkage errors and design the virtual simulator that can reduce the differences in the pilots' psychological effects.

Purpose: The etiology of temporomandibular disorders (TMDs) is complex and multifactorial including trauma, anatomical, pathophysiological, social and psychological factors. Psychological factors can induce or sustain TMDs in various ways. And psychological problems, such as anxiety and depression can be occurred due to TMDs. Therefore, evaluation of psychological factors in patients with TMDs is important. Although disc displacement (DD) is crucial in clinical situation, most of studies have focused on the relationship of psychosocial factors and myofascial pain. And also, Subtypes of DD can cause different degrees of discomfort, it is necessary to evaluate the psychological states of the patients according to the subtype. The Hospital Anxiety Depression Scale (HADS) is one of the self-report questionnaire to evaluate the psychological factors. HADS-Anxiety (HADS-A) and HADS-Depression (HADS-D) are assessed through 14 questions. The purpose of this study was to evaluate anxiety and depression assessed by HADS in patients diagnosed with subtypes of DD according to diagnostic criteria for TMDs. Methods: Four hundred thirty nine patients were diagnosed as one of the subtypes of DD. One hundred fourty nine subjects with no symptoms were set as control groups. All of them answered the HADS for Koreans. The cut-off score for anxiety and depression was set a score of 8. The chi-square test was performed to evaluate association between DD and anxiety/depression. Results: There was a significant difference in HADS-D between five groups (p<0.01). However, there was no significant difference in HADS-A. All the DD groups showed a significant difference in HADS-D compared with the control group except the DD without reduction without limited opening group. The DD without reduction with limited opening group showed the highest rates in HADS-D (40.4%). Conclusions: Based on the above results, it is necessary to consider the depression in treatment of the patients with DDs.

It is essential in evaluating the chronic pain patients that the physician obtain a multiple causative factors including organic, psychological, and socioenvironmental factors. Though these multiple factors are involved in the development of chronic pain syndrome, chronic pain syndrome is not only the sum of the interaction of all of these factors, but is also influenced by the sequelae of chronic pain, which again are organic, psychological, and socioenvironmental in nature. Therefore a systemic approach is probably the best way to asses the role of all of these factors. Furthermore, this approach can provide a framework for understanding chronic pain syndrome, for assessing chronic pain syndrome, for the rational management of chronic pain syndrome, and for the development and testing of hypotheses.
