The Effect of Core Job Characteristics on the PROTECTION of Medical Skincare Workers on the Organizational Effectiveness: With a Focus on the Mediating Effect of Self-Efficacy

Jieun Jang,Eunsook Kim J-INSTITUTE 2021 Protection Convergence Vol.6 No.3

Purpose: This study sought to examine the effect of core job characteristics, which is a concept related to the protection of medical skincare workers, on the organizational effectiveness with a focus on the mediating effect of self-efficacy. The aim is to help facilitate the development of the beauty service industry by promoting the achievement of organizational goals by securing professional manpower with job performance skills and by elevating the quality of the customer satisfaction services. Method: In this study, 405 copies of the online questionnaires for the medical skincare workers serving at skincare rooms and plastic surgery clinics by utilizing the IBM SPSS Statistics 25 program. To validate the effect of the core job characteristics of medical skincare workers on the organizational effectiveness by mediating self-efficacy, a 3 phased hierarchical multiple regression analysis was performed following the validation procedures of the mediating effect proposed by Baron & Kenny(1986) and the Sobel test was conducted to validate the mediating effect. Results: As a result of carrying out a 3 phased hierarchical multiple regression analysis in this study, in the first phase, among the sub-factors of the core job characteristics, which are the independent variables, job importance, feedback, job diversity, and autonomy, excluding job identity, were found to have sequentially impacted positively on the parameter of self-efficacy. In the second phase, among the sub-factors of the core job characteristics, which are the independent variables, autonomy, feedback, and job importance were found to have sequentially impacted positively on the dependent variable of organizational effectiveness. Lastly, the parameter self-efficacy and the independent variables of autonomy and feedback were found to have a positive effect on the organizational effectiveness. In the result of the Sobel test additionally conducted to validate the mediating effect, it was found that self-efficacy plays a mediating role in the relationship where job importance and feedback are impacting the organizational effectiveness. Conclusion: Based on the result of this study, it was validated that the job importance and feedback of the medical skincare workers increase the self-efficacy, and the increased self-efficacy in turn increases the organizational effectiveness. Hence, if self-efficacy is increased by providing feedback through education and a systematic inspection of their job with supervisors and colleagues for the perception of the importance of job for the members of organization, it will not only bring a positive effect on the performance of the organization, but also protect the employees, thereby promoting the achievement of organizational goals via efficient manpower management.

장지은(Jieun Jang),오민석(Min-Suk O),오정은(Jung-Eun Oh) 한국비교교육학회 2024 비교교육연구 Vol.34 No.4

[연구목적] 국가 간에 잦은 인구이동을 통하여 다문화 공생의 과제가 사회적으로 부각되는 가운데 본 연구에서는 한국에 유학하는 고급인재 유학생의 유학생활 만족도와 적응의 어려움 등을, 한국어 학습 경험에 따라 차이를 규명하여 한국어 학습지원과제를 도출하고자 하였다. [연구방법] 이러한 목적을 달성하기 위해 한국어 학습 집단과 비학습 집단에 의한 차이를 확인하였다. 이를 위하여 852명의 해외 고급인재 유학생을 대상으로 한 설문 조사 결과를 가지고 t 검정을 실시하였다. 그 결과는 다음과 같다. [연구결과] 한국어 학습 유무나 한국어 사용 유무는, 유학생활 만족도에 있어서 대학에서의 수업이나 학교 행정, 나아가 경제적 자원 조달 관련한 공적 영역의 유학생활 만족도에서는 집단 간 차이가 없다. 그러나 개인 생활의 차원이 되면, 건강과 안위, 그리고 일상생활 전반에서, 만족도에 있어서나 적응의 어려움에 있어서나 한국어 학습 및 사용 유무에 따른 집단 간 차이가 높게 나타났다. 즉 한국어 학습 집단, 그리고 한국어 사용 집단의 만족도가 높고 생활 적응에서의 어려움이 낮은 점이 분명하게 나타났다. [결론] 이러한 결과는 유학생이 주류사회의 언어를 학습하고 사용하는 것이 주류사회의 내부적 이해와 공감 그리고 적응력을 키우고 궁극적으로 정착을 통한 다문화 공생에 이바지할 수 있음을 보여주며 한국어 학습 지원 방향을 시사한다. [Purpose] Increasing population movements between countries have made the challenges of cultural diversity and multicultural coexistence a major social issue. This study examined the satisfaction of highly talented international students in Korea and some of the difficulties they face in the adaptation process. [Methods] This study explored the experiences of high-performing international students at a South Korean university, specifically examining differences in satisfaction between the students that learned some Korean and those that did not. A t-test analysis of survey responses from 852 students revealed some significant disparities between the two groups. [Results] While both groups reported similar levels of satisfaction with the academic and administrative aspects of university life, the members of the Korean-learning group exhibited significantly higher satisfaction and far fewer difficulties in their personal lives than the non-learning group. Specifically, Korean learners cited higher levels of satisfaction with regards to health, safety, and daily life in general, and less difficulty in adapting to life in Korea. [Conclusion] These findings highlight the importance of language proficiency in fostering successful adaptation and facilitating greater understanding, empathy, and adaptability among international students. Ultimately, the results of the study suggest that language acquisition can contribute to more harmonious and inclusive multiculturalism in the host society, and in Korea this carries implications for the importance of supporting Korean language learning among international students and other foreign residents.

노년기의 성공적 노화와 취로 활동 : 일본의 오가와노쇼 오야키무라 사례를 중심으로

장지은(Jang JiEun) 한국비교교육학회 2017 比較敎育硏究 Vol.27 No.3

본 논문은 고령자의 사회참여의 일 형식으로서 경제활동에 대한 대안적 인식의 필요성과 이에 따른 고령자 교육의 과제를 제기하기 위하여 추진되었다. 이를 위하여 일본의 ‘보람 취로’의 개념과 실천사례를 고찰하였다. 문헌연구를 통하여 일본의 국가 및 지자체의 고령자정책사업을 개관하는 가운데 그 특징을 살피어 보았다. 그리고 고령자들이 자주적인 회사설립을 통하여 추진한 사례, 오가와 노쇼 오야키무라의 실천을 현지방문과 인터뷰조사를 통하여 고찰하였다. 본 연구를 통하여 얻은 결과는 다음과 같다. 고령자의 경제활동은 성공적 노화의 관점에서 전개되어야 할 필요가 있고 이러한 경제활동은, 일본의 ‘보람취로’에서와 같이 다음과 같은 특징을 가진다. 첫째, 고령자상에 대한 변화된 인식이 필요하다. 고령자는 사회적 활용의 가치가 있는 경험자원을 가진 존재이다. 둘째, 고령자가 가진 경험자원을 사회적 가치로 창조하여 내는 교육과 기관경영이 필요하다. 셋째, 노년기에 부합한 일에 대한 유연한 인식이 필요하다. 즉 노년기의 심리적 고독경향, 사회적 단절 특성을 반영하고 이외에도 의미있는 존재가 되고 싶은 노년기의 요구를 반영한 일의 고안이 필요하다. 그러므로 향후 고령자 교육은 보람취로의 관점에서 일 교육에 대한 방침과 실천을 고안할 필요가 있다. The purpose of this study is to raise the necessity of an alternative awareness toward economic activities as the work form of social participation by the elderly and their corresponding educational tasks. For this aim, the concept of Japan’s ‘rewarding work participation’ and its practical cases have been examined. As a study method, the characteristics of Japan’s state and local government elderly policy projects have been examined through literature research. Next, the cases of the elderly having established an autonomous company and practiced Ogawanosho Oyakimura were researched based on on-site visits and interviews. As this study has suggested that the economic activities of the elderly have to be carried out from the perspective of successful aging and these activities have been conducted through ‘rewarding work participation’, the following features have been clarified. First, a converted image of the elderly is necessary. The elderly do have the experiences worthy of social utilization. Second, the educational and managerial policies which turn the elderly’s experiences into social values are necessary. Third, a flexible awareness toward the corresponding works of the elderly is needed. In other words, the works which have reflected mentally solitary tendency and social discontinuity features of the elderly and taken into account the demands of the elderly generation who desire to become an influential and meaningful existence are necessary. Thus, future elderly education need to come up with the policies and practices toward work education from the viewpoint of rewarding work participation.

Background: In this study, we aimed to investigate the interaction effects of individual socioeconomic status and regional deprivation on the onset of diabetes complications and diabetes-related hospitalization among type 2 diabetes patients. Methods: Korean National Health Insurance Service National Sample Cohort data from 2002 to 2013 were used. A total of 50,954 patients newly diagnosed with type 2 diabetes from 2004 to 2012 and aged 30 years or above were included. We classified patients into six groups according to individual income level and neighborhood deprivation: ‘high in advantaged,’ ‘high in disadvantaged,’ ‘middle in advantaged,’ ‘middle in disadvantaged,’ ‘low in advantaged,’ and ‘low in disadvantaged.’ We calculated hazard ratios (HR) of onset of diabetes complication and diabetes-related hospitalization using the Cox proportional hazard model, with the reference group as diabetes patients with high income in advantaged regions. Results: In terms of the interaction effects of individual income level and regional socioeconomic level, even with the same low individual income level, the group with a high regional socioeconomic level (low in advantaged) showed low HRs for the onset of diabetes complication (HR, 1.04; 95% confidence interval [CI], 1.00-1.08) compared to the ‘low in disadvantaged’ group (HR, 1.10; 95% CI, 1.05-1.16). In addition, the ‘high in advantaged’ group showed slightly higher HRs for the onset of diabetes complication (HR, 1.06; 95% CI, 1.00-1.11) compared to the ‘low in advantaged’ and it appeared to be associated with slight mitigation of the risk of diabetes complication. For the low-income level, the patients in disadvantaged regions showed the highest HRs for diabetes-related hospitalization (HR, 1.29; 95% CI, 1.19-1.41) compared to the other groups. Conclusion: Although we need to perform further investigations to reveal the mechanisms that led to our results, interaction effects individual socioeconomic status and regional deprivation might be associated with on onset of diabetes complications and diabetes-related hospitalization among type 2 diabetes patients.

Rheum palmatum has traditionally been used as a preventive agent and medication against fever and infection. The aim of this study was to isolate and characterize an antibacterial substance from R. palmatum that is effective against bacterial vaginosis. A methanol extract from R. palmatum showed antibacterial activity against Lactobacillus vaginalis KC TC 3515, Chryseobacterium gleum KCTC 2904, and Sphingomonas paucimobilis KCTC 2834, which cause bacterial vaginosis. After extraction and pH control of the methanol extract from R. palmatum, we found that acidic and alkaline extracts did not show antibacterial activity. A neutral extract (50 mg/mL) displayed an inhibitory zone of 18 mm on a nutrient agar plate with C. gleum KCTC 2904. Fractions No. 11 and 12 among 41 fractions obtained by silica gel column chromatography produced inhibitory zones of 10 mm on nutrient agar plates with C. gleum KCTC 2904. Rf0.15 and Rf0.17 spots produced by TLC of fraction No. 11 showed antibacterial activity against C. gleum KCTC 2904. Isolation and purification of the peak at a retention time (Rt) of 9.427 min was achieved by HPLC of Rf0.29spots. The peak at Rt 9.427 min showed antibacterial activity against C. gleum KCTC 2904.

Bio-jet fuel has been proposed as a powerful tool for reducing carbon dioxide in the aviation sector. Among the specifications of bio-jet fuel, flash point is a very important specification related to safety during storage, transport and use, but there is a lack of research on it. In this study, we investigated the molar fraction of hydrocarbons in bio-jet fuel produced by the HEFA process from palm oil to predict the flash point of bio-jet fuel based on Raoul’s law. The predicted flash point results were compared with the flash point measured by the tag-closed cup test method. As a result, the predicted flash point of bio-jet fuel was similar to the measured flash point, and a correlation of 0.90 was found. This confirms that the flash point of bio jet fuel can be predicted.
