  • In this paper, a composite material analysis program based on the finite element method(FEM) is used. The purpose of this study was to verify whether the composite material analysis program which developed as part of a project of development of softwares and educational contents for structural vibration and composite material analysis that can calculate how similar the macroscopic mechanical behavior of the composite materials actually. Because composite materials are generally anisotropic, analysis of composite laminate is used for the constitutive equations of orthotropic material. For convenience, the unit is ommited in all calculations. To verify the accuracy of the finite element method based program, the deflection and stress distribution of the simply supported composite material laminated plate subjected to a uniform load distribution is compared with exact solution. Size and properties of the composite material laminate used for analysis are fixed variables, and by changing the number of elements and the total thickness of the laminate is compared with the exact solution to the resulting value, respectively.

  • Objectives: This study aims to alleviate dental hygienists' job stress caused by emotional labor, lower their turnover rate, improve the working environment, and offer better quality of services by understanding correlations among emotional labor, job characteristics, job stress, and turnover intention. Methods: A survey was conducted in the subjects with dental hygienists who were working at general hospitals, dental university hospitals, and private dental clinics located in Seoul, Gyeonggi, and Chungnam by the convenience sampling method from June 1 through 30, 2017, and the collected data were analyzed using by SPSS Windows Ver. 22.0 (IBM CO, Armonk, NY, USA) and AMOS 21. As the statistical analysis methods, convergent validity test, structural equation model analysis and model goodness of fit were conducted using independent samples t-test, one-way ANOVA, path analysis, and confirmatory factor analysis. Results: It turned out that the more dental hygienists' deep acting of emotional labor and the more their workload of job characteristics, the higher their job stress got, and that the higher their job stress, the higher their turnover intention got. Conclusions: As a method of lowering dental hygienists' turnover intention, they may resolve emotional disharmony with their own problem-solving method, but it is necessary to develop and support organizational culture for the improvement of working environment. Dental hygienists' organizations should implement the measures to minimize their turnover rate and job stress level by allocating appropriate workload.

  • Objectives: The objectives of this study were to investigate female labor workers' occupational stress and musculoskeletal symptoms and to identify the effects of their occupational stress and musculoskeletal symptoms on their health-related quality of life. Methods: A survey was conducted through direct interviews using a musculoskeletal symptoms questionnaire, the Korean Occupational Stress Scale(KOSS), and the Short-Form 36-Item Health Survey(SF-36). Subjects were 112 female labor workers in three factories in D city who were selected by convenience sampling. Results: Factors significantly affecting health-related quality of life were found to be: occupational stress(${\beta}$=-.36); degree of pain, with medium pain(${\beta}$=-.31) and extremely severe pain(${\beta}$=-.24); duration of pain, with more than 1 week-less than 1 month(${\beta}$=-.25) and more than 6 months(${\beta}$=-.16); frequency of pain, with once per 2-3 months(${\beta}$=-.22); responses to pain such as medical leave, use of worker's compensation insurance, task change, etc.(${\beta}$=-.16), and Slightly difficult(${\beta}$=-.16) versus Not hard at all. These variables demonstrated that health-related quality of life is 48%(F=11.72, p<.001) in female workers. Conclusions: To improve female labor workers' health-related quality of life based on the above results, occupational health managers should reduce the workers' occupational stress, develop and apply health interventions regarding musculoskeletal symptoms, prevent the early onset of musculoskeletal symptoms, and protect and promote the workers' health.

  • The purpose of the study was to identify the factors influencing the nursing students' job-seeking stress. A cross-sectional descriptive survey, using a structured questionnaire, was used to collect data from Sep. to Oct. 2016. A sample of convenience was 246 nursing students and a questionnaire was used to measure their major satisfaction, CDMSE, self-esteem, ego-resiliency, and job-seeking stress. A significant negative correlation was found among job-seeking stress, major satisfaction, CDMSE, self-esteem, and ego-resiliency. Grade of which the participant was in, self-esteem, academic achievement, experience of clinical practice, and family economic status were significant predictive variables of which accounted for 46.1% of the variance in job-seeking stress. The results from this study can be used to develop programs for job-seeking stress management.

  • Objectives: The purpose is to prepare measures to effectively improve college life adaptation by identifying relevance between interpersonal relation disposition and college life adaptation, college life stress and college life adaptation for dental hygiene students. Methods: 375 dental hygiene students attending some local universities in Gyeonggi-do were sampled for convenience. The results of this study are as follows. Results: First, As a result of interpersonal relation disposition according to general characteristics, superiority-dominance tendencies were higher in first and third graders, in groups with grades above 4.0 and groups with lower subjective economic levels. And the stress of college life was high for second graders and students with lower grades than 2.0. Second, According to the correlation between factors, governance-dominance, independence-responsibility, sympathy-acceptance, sociable-friendliness, and ostentation-intoxication of interpersonal tendency factors had proportional relationship with college life adaptation, rebellion-distrust and college life stress had inverse relationship. Third, The results of multiple regression analyses to identify factors that affect college students' adaptation to college life were in the order of stress in college life, first grade, sociable-friendliness, second grade, rebellion-distrust. Conclusion: In order to improve college life adaptation, counseling and practical mediation programs should be developed and applied to effectively manage and control the negativity and positivity implied by interpersonal relationships and college life stress.

  • With the globalization of Korean education and the rise in the average level of education, the number of international students in Korea, especially those from China, is rapidly increasing every year. This study aimed to provide the basic information for healthy dietary education by evaluating the dietary and nutritional status of Chinese students living in Gwangju province of Korea. Data from 468 subjects who met the study participation criteria and who had given their written informed consent were used for analysis. Of the total subjects, 52.4 and 80.1% were non-drinkers and non-smokers, respectively (p<0.01). It was observed that women were more stressed than men when they did not have convenient access to a Chinese food market near their place of residence (p=0.032). The subjects with a high cultural adaptation consumed kimbap (p<0.001) and pizza (p=0.017) more frequently than the subjects with a low cultural adaptation. An analysis of the nutrient quotient revealed that male scores were higher than those of the females with regard to water intake (p=0.035) and exercise level (p=0.021). For Chinese students living in Korea to maintain proper dietary habits, it is necessary to educate them on how to purchase convenience foods and improve their lifestyle, including limiting drinking and smoking. It is also necessary to develop emotional support programs for stress management and cultural adaptation.
