본 연구는 B화력 직원들이 대형화재의 위기관리 복구과정에서 인지했던 심리적 소진과 집단주의가 조직몰입에 미치는 영향을 파악하기 위하여 소진, 집단주의, 조직이미지, 외부이미지, 직무만족과 조직몰입 간의 경로모형을 검증 및 구축하였다. 자료수집은 B화력 조직원 286명에게 구조화된 설문지로 자기기입법에 의한 설문조사를 실시하였고, SPSS와 AMOS 프로그램을 이용하여 분석하였다. 가설모형의 전반적인 적합도는 양호하였다(=5.52, p=.05, GFI=.992, CFI=.981, IFI=.982, AGFI=.913, RESEA=.083, SRNR=.032). 본 연구의 가설적 모형에 대한 분석결과, 대상자는 조직몰입에 대하여 소진, 집단주의 및 직무만족이 직접효과와 총효과를 갖는 것으로 나타났다. 또한 조직이미지와 외부이미지는 조직몰입에 대하여 간접효과와 총효과가 유의한 것으로 나타났으며, 모형의 설명력은 72.9%였다. 본 연구결과를 토대로 위기관리에 대처하여 조직몰입을 높이기 위해서는 조직구성원들의 소진 중재 프로그램개발이 필요하며, 집단주의, 조직이미지, 외부이미지 및 직무만족을 높이기 위한 방안 모색이 필요하다.

Purpose) The purpose of this study is to understand the college students' needs for the development of learning contents in English pronunciation education using virtual reality (VR). (Design/methodology/approach) The survey was conducted using a structured questionnaire for 281 college students in D University from January 3-10, 2020. The questionnaire consists of questions related to English learning status, awareness of VR based English pronunciation learning, educational contents and methods. (Findings) Among English learning contents, 80.2% of the students chose ‘travel’ for their preferred contents. The findings reveal that the students expected that VR-based English learning contents should be developed based on speaking and listening (72.2%), learners’ selective use (75.0%), consideration of the difficulty level according to the individual learner’s level (81.3%) and preference (77.9%). In addition, there was a significant difference in the subjective level of English competencies as the 'very good' group showed high knowledge of VR, future utilization, and intention to participate in VR English education program (P <0.05). (Research implications or Originality) Therefore, the findings of this research suggest that English pronunciation learning contents using VR can be useful in English education when developed as a customized program reflecting the individual learner’s level.

Objectives: This study conducted a literature review to systematically confirm the quantitative results of individual studies on oral health-related quality of life (OHRQoL) among elderly adults. Methods: Studies on quality of life related to oral health among Korean elderly adults were selected as targets, and literature published in Korean journals until January 10, 2019, was examined. A total of 179 papers were reviewed using RISS, KISS, eArticle, and DBpia, and 17 papers meeting the final conditions were selected for analysis. Factors were categorized with publication year, sample size, gender, and statistical analysis as main variables. Relevant factors and effect sizes were then encoded, and the values of correlation coefficients and correlation effect sizes were coded. Results: After classifying the factors affecting OHRQoL among elderly adults according to common characteristics, four studies related to food and diet, five studies related to xerostomia, and four studies related to dentures and denture satisfaction were found to be related. Conclusions: Overall, various factors affected OHRQoL among elderly adults. Therefore, oral health among elderly adults must be developed and managed considering the various factors related to OHRQoL.
A STUDY OF A NUCLEAR HYDROGEN PRODUCTION DEMONSTRATION PLANT
장종화 한국원자력학회 2007 Nuclear Engineering and Technology Vol.39 No.2
The current energy supply system is burdened by environmental and supply problems. The concept of a hydrogen economy has been actively discussed worldwide. KAERI has set up a plan to demonstrate massive production of hydrogen using a VHTR by the early 2020s. The technological gap to meet this goal was identified during the past few years. The hydrogen production process, a process heat exchanger, the efficiency of an I/S thermochemical cycle, the manufacturing of components, the analysis tools of VHTR, and a coated particle fuel are key areas that require urgent development. Candidate NHDD plant designs based on a 200 MWth VHTR core and I/S thermochemical process have been studied and some of analysis results are presented in this paper.

Objectives: The purpose of the study is to investigate the effect of chewing gum containing Prunus mume extract(PME) on the change of saliva ingredients. On the basis of the biological background of molecules and diagnostic indices in the use of saliva, the mastication effect of chewing gum containing PME was demonstrated in terms of secretory IgA concentration and total protein concentration in stimulated saliva. Methods: This study is an experimental research on the use of a research design before and after applying a randomized control group. Participants were distributed randomly to the experimental group and the control group, respectively. The experiment group was instructed to masticate the chewing gum containing PME for 10 minutes for one month after each meal within 30 minutes. Salivary secretion was collected by the participants between 8 and 10 a.m in the morning in the research office. For the measurement of secretory IgA and total protein concentrations in the saliva, indirect enzyme-linked immunosorbent assay(ELISA) was used. Results: The salivation stimulation rate was significantly increased after four weeks of masticating chewing gum containing PME after each meal(p<0.001). Mastication of chewing gum containing PME for four weeks decreased the concentration of secretory IgA much more significantly than that after mastication for one week(p=0.003). The concentration of total protein in the saliva was decreased after four weeks in the experimental and control groups. Conclusions: Mastication of chewing gum containing PME stimulated salivary secretion and led to oral disease prevention in patients with xerostomia. Furthermore, it seems to be urgent to seek measures that can be utilized in intervention for patients with xerostomia.
