본 연구의 목적은 항공사 객실승무원의 완벽주의 성향이 직무열의와 팀 몰입에 미치는 영향관계에서 LMX의 조절된 매개효과를 살펴보는 것이다. 가설검증을 위하여 각 변수별 선행연구를 고찰하고 설문지를 작성하였으며, 편의 표본 추출방법을 통해 국내외 항공사에 근무하는 객실승무원 중 현재 항공사에서 1년 이상 근무하고 있는 직원을 대상으로 연구를 진행하였다. 총 324부를 연구에 활용하였고 수집된 자료는 SPSS 25.0과 PROCESS Macro 3.5 통계프로그램을 사용하여 분석하였다. 조사대상사의 인구통계학적 특성을 확인하기 위하여 빈도분석을 시행하였으며, 각 측정항목의 일관성을 평가하고 측정도구의 신뢰성과 타당성을 검증하기 위한 확인적 요인부석과 신뢰도 분석을 실시하였다. 또한 가설검증을 위해 PROCESS Macro Model 4번 및 7번 모형을 통해 가설을 검증하였다. 가설검증의 결과 첫째, 항공사 객실승무원의 완벽주의 성향은 팀 몰입에 유의한 정(+)의 영향을 미치는 것으로 나타났다. 둘째, 완벽주의 성향과 팀 몰입 간의 영향관계에서 직무열의는 매개효과를 가지는 것으로 나타났다. 셋째, LMX는 완벽주의 성향과 직무열의간의 영향관계에서 조절효과를 가지는 것으로 나타났다. 넷째, 완벽주의 성향과 팀 몰입간의 관계에서 직무열의의 매개효과에 대해 LMX는 조절된 매개효과를 가지는 것으로 나타나 LMX 수준이 낮아질수록 직무열의를 거쳐 팀 몰입으로 가는 효과가 더욱 증가하는 부(-)적인 조절효과를 확인하였다. 이러한 실증분석을 결과를 통하여 객실승무원의 완벽주의 성향과 직무열의, LMX는 팀 몰입에 영향을 미치는 중요한 원인변수임을 확인하였으며 학문적 시사점과 실무적 시사점, 향후 연구의 방향을 제시하였다. The purpose of this study is to examine the controlled mediating effect of LMX in the relationship between the perfectionism tendency of airline cabin crew on job enthusiasm and team commitment. To verify the hypothesis, previous studies for each variable were reviewed and a questionnaire was prepared, and a study was conducted on cabin crew members working at domestic and foreign airlines for more than a year through a convenience sampling method. A total of 324 copies were used in the study, and the collected data were analyzed using SPSS 25.0 and PROCESS Macro 3.5 statistical programs. Frequency analysis was conducted to confirm the demographic characteristics of the surveyed companies, and confirmatory factor analysis and reliability analysis were conducted to evaluate the consistency of each measurement item and to verify the reliability and validity of the measurement tool. In addition, for hypothesis verification, the hypothesis was verified through PROCESS Macro Model 4 and 7. As a result of hypothesis verification, first, it was found that the perfectionism tendency of airline cabin crew had a significant positive (+) effect on team commitment. Second, it was found that job enthusiasm had a mediating effect in the relationship between perfectionism and team commitment. Third, LMX was found to have a moderating effect in the influence relationship between perfectionism and job enthusiasm. Fourth, LMX was found to have a moderated mediating effect on the mediating effect of job enthusiasm in the relationship between perfectionism and team commitment, confirming a negative (-) moderating effect that increases the effect of going to team commitment through job enthusiasm as the LMX level decreases. Through this empirical analysis, it was confirmed that cabin crew's perfectionism tendency, job enthusiasm, and LMX are important cause variables that affect team commitment, and academic implications, practical implications, and future research directions were presented.

Recent studies revealed that human obesity is associated with the relative abundance of the two dominant intestinal bacterial phylums, the Bacteroidetes and the Firmicutes. In this study we screened out the functional food components from various Basidiomycota to improve human intestinal microflora, especifically to promote growth of Bacteroides spp that belongs to Bacteroidetes and to inhibit growth of Eubacterium spp that belongs to Firmicutes. The 80% ethanol extract of Gyrophora Esculanta was effective in inhibiting Clostridium spp and Eubacterium spp and the water extract of Coriolus versicolor judae was effective in increasing the growth of Bifidobacterium spp and Bacteroides spp. The feeding of Gyrophora Esculanta and Coriolus versicolor judae extracts increased the body and kidney weight of rats. The concentration of total cholesterol, HDL-cholesterol and TG were not decreased in the rat fed Gyrophora Esculanta. But the concentration of LDL-cholesterol was decreased. In case of Coriolus versicolor judae, the concentration of total cholesterol, HDL-cholesterol and TG was decreased. These results showed the possibilities of Coriolus versicolor judae and Gyrophora Esculanta as a functional food components to control intestinal microbial flora.

The purpose of this thesis is to investigate how children with mental retardation can improve communicative skills in the context of boardgames. Four children aged between 7 and 12 (three boys and one girl) participated in this experiment. The frequency of communication with other subjects, modes of communication, i.e. nonverbal and verbal, and the intention of communication with other subject are used to evaluate communicative skill improvement. The results of this research are as follow: First, the intervention using boardgames increased the frequency of communicative expression of four subjects during 20 sessions. Note that these increased communication among four subjects, however, is not statistically non-significant. Second, regarding communicative expression's modes, the intervention using boardgames was too limited effects on the subjects so that the use of gesture/vocalization decreases and the use of speech increases, which implies the development of communicative competence in a positive way. On the other hand, since the boardgames required gesture as well as a lot of speech, it did not affect change of communicative expression's modes. Third, it is shown that the intervention using boardgames diversified the intentions of communicative expression of the subjects during the sessions. This indicates that the frequency of each intention increased. This result, however, statistically non-significant. In conclusion, this study shows that the intervention using boardgames for mentally retarded children had constructive effects on increasing the frequency and expanding intentions in communicative expression.
