This study was conducted in Seoul and Chungcheong-do to examine the intention of workers in the hair care service industry to be immersed in the organization and to change jobs. The data collection was distributed 350 copies of the questionnaire to those in the hair care industry, 320 copies were collected, and 281 copies were used for analysis except for insincere surveys. An empirical analysis was performed using SPSS 21.0 to analyze frequency, factor, reliability, and regression. As a result of the analysis, the conflict factors were divided into five factors: compensation conflict, internal characteristics in the workplace, job autonomy, relationship conflict, and work environment, and organizational immersion was divided into three factors as continuous, emotional, and normative immersion, and the intention to change jobs was divided into a single factor. Among the factors of conflict, the compensation conflict has had a significant impact on both continuous, emotional and normative immersion, which is common to organizational immersion. Among the factors of conflict, compensation conflicts, task autonomy, relationship conflicts and work conditions affected the intention of turnover, and continuous and emotional immersion affected the intention of turnover, but normative immersion was confirmed to have positive effects. In other words, raising the trust in the organization and the normative immersion, which is a sense of belonging, to reduce the turnover rate is judged to be reduced. Therefore, it is judged that in the hair and beauty service industry, compensation conflicts should be resolved not only through financial compensation but also through motivation or work benefits that can satisfy workers’ desire for conflict. If a representative or branch manager of the hair care service industry shares his or her thoughts with the members of the organization and has an open mind, it is believed that a happy working life will reduce conflict and intention to change jobs, and improve confidence in the organization and immersion in the job. However, the study was conducted only by employees in the hair care service industry based in Seoul and Chungcheong provinces, so it is not common to judge the causes of conflicts, organizational immersion and intention to change jobs while working across the country. It is hoped that future research will produce more meaningful follow-up results if the research is carried out by supplementing the contents presented later.

장두현 한국미용예술경영학회 2019 미용예술경영연구 Vol.13 No.1
본 연구는 서울지역에 소재한 4년제 미용학과를 재학 중인 대학생들을 연구대상으로 하여 학업적 자기 효능감이 대학생활 만족도에 어떠한 영향을 미치는지에 대하여 알아보고자 하였다. 수집된 자료는 SPSS 21.0을 사용하여 빈도분석, 요인분석, 신뢰도 검증, 상관관계 분석, 다중회귀분석, 일원변량분석(ANOVA)을 실시하였다. 연구의 결과는 다음과 같다. 첫째, 본 연구의 조사대상자는 여성이 많았으며 1학년이 제일 많았고 성적은 중, 그리고 헤어전공이 많았다. 이들은 대부분 적성이나 흥미로 미용을 선택하였고 미용학과를 대체로 만족하는 것으로 조사 되었다. 둘째, 학업적 자기효능감과 대학생활 만족도의 차원을 알아본 결과 학업적 자기효능감은 학업적 효능감, 학습 난이도 조절, 학업 자신감의 세 가지 요인으로 나타났으며 대학생활 만족도는 정의적, 심리적, 환경적, 학업적, 사회적 적응의 다섯 가지 요인이 도출되었고 학업적 자기효능감의 하위요인별 학업적 효능감, 학습 난이도 조절은 대학생활 만족도의 하위요인별 사회적, 학업적, 심리적, 정의적, 환경적 적응과, 학업적 자기효능감의 하위요인별 학업 자신감은 대학생활 만족도의 하위요인별 사회적, 심리적, 학업적 적응과 통계적으로 유의미한 정(+)의 상관관계가 있는 것으로 각각 나타났다(p<.01). 셋째, 일반적 특성에 따른 학업적 자기효능감의 차이를 알아본 결과 학년, 성적, 전공, 미용전공 선택 이유, 미용학과 만족도는 하위요인별에 따라 각각 유의미한 차이가 나타났다. 넷째, 일반적 특성에 따른 대학생활 만족도의 차이를 알아본 결과 학년, 성적, 전공, 미용전공 선택 이유, 미용학과 만족도는 하위요인별에 따라 각각 유의미한 차이가 나타났다. 다섯째, 학업적 자기효능감이 대학생활 만족도에 미치는 영향에 대해 알아본 결과 학업적 적응에 있어서는 학업적 효능감, 학습 난이도 조절, 학업 자신감이 중요한 요인임을 알 수 있었고, 사회적 적응과 심리적 적응에 있어서는 학업적 효능감, 학업 자신감이 중요한 요인이었으며, 정의적 적응은 학업적 효능감, 학습 난이도 조절이, 환경적 적응에서는 학업적 효능감이 중요한 요인임을 알 수 있었다. 향후 연구에서는 학업적 자기효능감과 대학생활의 만족에 따라 진로선택에 어떠한 영향을 미치는지와 또는 전국의 4년제 미용전공대학교와 재학생들뿐만 아니라 2년제 미용전공전문대학교와 전문대학 재학생들을 비교하는 후속 연구를 통해서 다양한 개선방안을 제시할 수 있는 기초자료로 활용되어 좀 더 객관적이고 명확한 연구결과가 도출되기를 기대한다.

Asthma is recognized today as an inflammatory disease of the lung characterized by acute non-specific airway hypersensitiveness in association with chronic pulmonary inflammation. Gamijihwang-tang(GJT), a fortified prescription of YMJHT, is applied for the treatments of chronic coughing and asthma, and post-delivery coughing and asthma in the gynecology. Also in the clinical practice, GJT is known to be very effective for controlling coughing and asthma as a cold sequela. In this study, we investigated the effects of GJT on the lipopolysaccharide (LPS)-induced nitric oxide (NO) and prostaglandin E2 (PGE2) production, and on the level of inducible nitric oxide synthase (iNOS) and Cyclooxygenase-2 expression in murine macrophage RAW 264.7 cells. We found that GJT inhibited LPS-induced NO and PGE2 production in a dose dependent manner. Furthermore, GJT inhibited the expression of LPS-induced iNOS and COX-2 protein and mRNA expression in RAW 264.7 macrophages. Treatment with GJT of RAW 264.7 cells transfected with a reporter construct indicated a reduced level of LPS-induced nuclear factor-κB (NF-κB) activity and effectively lowered NF-κB binding as measured by transient transfection assay. These results suggest that the main inhibitory mechanism of the GJT may be the reduction of iNOS and COX-2 gene expression through blocking of NF-κB activation.

무인항공기는 유인항공기에 비하여 선진국과의 기술 격차가 크지 않고 아직도 초기 시장형성 시기로써 잘만 준비한다면 우리나라가 세계시장 경쟁에서도 승산이 있다고 판단된다. 따라서 본 논문은 해외 시장분석 전문기관들이 본 향후 10년간의 세계 무인항공기 시장 동향과 전망을 기초로 무인항공기의 지역별, 시기별, 종별 시장전망을 논해 본다. Unlike the manned aircraft, the UAS technological gap between korea and developed countries is marginal and, furthermore, the UAS market is yet to be matured. Thereby, with a well preparation, the author believes korea"s UAS possesses competitive power in the worldwide markets. This paper discusses ten-year forecasts by region, period, and classes of UAVs based on the worldwide UAS market forecasting data published by international UAS market analysis agents.

Objectives : This study investigated the improvement effects of Gangjihwan (DF) and combination of Gangjihwan and Gamisochehwan (GSH) on nonalcoholic fatty liver disease in a high fat diet-induced obese mouse model. Methods : Eight-week-old C57BL/6N mice were divided into five groups: a normal lean group given a standard diet, an obese control group given a high fat diet, and atorvastatin, DF, and DF+GSH groups given a high fat diet with atorvastatin (10 mg/kg), DF (40 mg/kg), and DF+GSH (80 mg/kg), respectively. After 8 weeks of treatment, body weight gain, blood lipid markers, ALT concentrations, liver weight and histology were examined. Results : 1. Body weight gain was significantly decreased in DF, DF+GSH and atorvastatin groups compared with control. The extent of decreases was eminent in DF+GSH group. 2. Circulating concentrations of total cholesterol, HDL-cholesterol and LDL-cholesterol were decreased in DF, DF+GSH and atorvastatin groups compared with control. The decreases were significant in DF+GSH and atorvastatin groups. 3. Liver weights were decreased in DF, DF+GSH and atorvastatin groups compared with control. In particular, liver weight was significantly reduced only in DF+GSH group. 4. Hepatic lipid accumulation was significantly decreased in DF, DF+GSH and atorvastatin groups compared with control, and the magnitude of which was more effective in DF+GSH group than in DF-only group. 5. Circulating ALT concentrations were decreased in DF, DF+GSH and atorvastatin compared with control, but ALS levels were significantly reduced only in DF+GSH group. Conclusions : In conclusion, these results suggest that DF decreases body weight gain, improves blood lipid metabolism, and reduces liver weight and hepatic lipid accumulation, contributing to the improvement of nonalcoholic fatty liver disease. In addition, these effects were more effective in DF+GSH combination group than in DF-only group.
