Purpose: This study intends to provide decision-making information to improve efficiency by analyzing the management efficiency of smart greenhouse business entities and identifying factors that affect the efficiency based on input and output. Methods: The subjects of analysis were business entities for cultivating strawberries in smart greenhouses in Jeolla region (northern and southern Jeolla provinces), and the analysis focused on the management performance of the 2019-2020 crop period (year). Data Envelopment Analysis(DEA) was applied as an analysis method for efficiency analysis, Quantile Regression(QR) analysis was applied as a factor affecting the efficiency. Results: The reason for the efficiency gap between business entities was that there were many business entities that did not minimize the input cost at the current level of output, and the area where the variance among business entities was large was the fixed cost per 10a. In the results of the affecting factor analysis, it was found that the seed-seedlings cost, fertilizer cost, other material cost, and employment and labor cost had a negative (-) effect on the efficiency, and that the repair and maintenance cost had a positive (+) effect. Conclusion: Therefore, to achieve the efficiency of scale, it is necessary to reduce the input scale to an appropriate level. In the case of business entities with low efficiency by quartile, the seed-seedlings, fertilizer, and other material costs reduce expenditures, and repair maintenance costs can improve efficiency by increasing expenditures.

한국장학재단에서 학자금 대출제도가 시행되기 전에는 은행 등 금융회사를 통해 학자금 대출제도가 시행되고 있었지만, 한국장학재단 설립된 이후는 재단이 직접 학자금을 대출함으로써 정부의 역할은 강화되었다. 하지만, 학자금 대출의 상환실적이 저조하여 향후 학자금 대출의 상당한 부실과 정부의 재정적 부담이 우려되고 있다. 더구나 학자금 대출은 저소득층 지원을 위하여 대학을 졸업한 이후에도 상환이 이루어지기 때문에 채무자의 향후 취업률과 소득수준이 개선되지 않는 한 학자금 대출의 상환율이 개선될 가능성은 매우 희박하다. 본 논문에서는 빅데이터 기반 시스템에서 수집, 저장, 처리, 분석 단계를 거쳐 학자금 대출의 상환 금액을 최종 시각화 그래프를 표현하였다. 이는 학자금 대출에 대한 금액을 눈으로 확인하여 현재 학자금 대출제도에 대한 부담을 줄일 방안을 다양하게 생각해 낼 수 있는 근거자료가 될 수 있다.

Background: A study was conducted to check the occupational personality competency status of students enrolled in the three-year dental hygiene department and to understand the contents of vocational personality education to be prepared according to these results. Methods: For 240 students enrolled in the Department of Dental Hygiene in Area, Daegu, the College Student Occupational Personality Scale (OPSU) was administered. Results: The higher the major satisfaction (F=10.589, p<0.000) and the higher the major performance (F=3.704, p<0.01), the higher the vocational personality competency. The average occupational personality competency for job adaptation was 3.96±0.47 points (out of 5 points). As for the average for each sub-area, consideration was the highest at 4.51±0.42, and confidence was the lowest at 3.54±0.84. Among professional personality competencies, the average of each sub-area showed the highest positive correlation in the order of positivity (r=0.835, p<0.00), reliability (r=0.769, p<0.00), and community consciousness (r=0.767, p<0.00), and consideration (r=0.696, p<0.00) showed the lowest correlation. Conclusions: Personalized career and employment education should be provided in consideration of the individual occupational personality level of dental hygiene students considering the characteristics of the health and medical fields, and individual counseling should be provided in areas that are insufficient or supplemented. In addition, dental hygiene ethics education is necessary for the development of vocational personality competencies in the dental hygiene curriculum, and universities should spare no support for completing vocational personality education programs in preparation for the future society by using comparative programs.

Relatively little studies have investigated employee recovery from internal service failure, especially from the employees' perspective. When handling customer complaints, employees must not only deal with legitimate customer demands after a service failure, such as providing an apology, rectifying the problem, and offering compensation, but they must also manage illegitimate dysfunctional customers, who may yell, threaten, and even physically harm the employee. These negative experiences can have strong effects, and employees can exhibit higher levels of stress such as burnout and emotional labor, which have been linked to dissatisfaction, tension and anxiety, reduced performance and effectiveness, and a greater propensity to leave the firm, ultimately leading to negative financial consequences for the firm. These conditions result in internal service failure and create the need to recover employees-in other words, internal service recovery. However, little research has examined this issue so far. The purpose of the current study, therefore, is to investigate the relationship between internal service recovery and employee outcomes. A pre-test, post-test between-subjects experimental design was developed. Participants were 166 part-time students who were working full-time. The average age of the participants was 36.74 years, and 57.50% of them were female. The average length of employment was 13 years. Participants were randomly assigned to one of four groups of approximately equal size. Three of the groups were subjected to an experimental situation involving an internal service failure, while one group was not exposed to failure, thereby acting as a control group. This study contributes to the service marketing literature in several ways. First, the study extends service failure and/or recovery research by examining recovery in an employee context. Second, this study attempts to measure internal service recovery and to empirically demonstrate its relationship to employee outcomes. Third, this investigation emphasizes the managerial importance of internal service recovery. For example, understanding the nature of the relationships between internal service recovery and its consequences can improve the effectiveness and efficiency of managers' resource allocation decisions.

Purpose : Delegating authority to employees exerts a positive effect on the efficient operation and service of a company. In particular, investigating how the delegation of authority granted to social workers, who have a greater workload compared with those of other occupations, influences job satisfaction and commitment to the organization is meaningful. Therefore, this study aims to investigate the impact of the empowerment of social workers on job satisfaction and organizational commitment. Methods : Toward this end, surveys were distributed to social workers employed at social welfare facilities in Daegu metropolitan city. Prior to the study, the researcher visited the institutions in which the social workers were working, explained the content in person, and conducted the self-administered survey accompanied by two research assistants who received prior training. Out of the 233 collected responses, those with unreliable responses and missing data were excluded, which left a sample of 224 for analysis. Data were analyzed using SPSS 18.0. Results : First, social workers who were older, had higher positions, and with longer years of service exhibited higher levels of empowerment in terms of differences in empowerment according to general characteristics. Second, for job satisfaction and organizational commitment according to general characteristics, the longer the period of employment, the higher the level of job satisfaction. Third, empowerment exerted an effect on job satisfaction and organizational commitment, and a positive correlation was found. Conclusion : The empowerment of social workers exerted a positive effect on job satisfaction and organizational commitment. Therefore, to improve service quality and the efficient operation of social welfare organizations in this practice, improving the empowerment of social workers is necessary by providing appropriate treatments, improving working environments, and providing appropriate discretion and decision-making authorities that are considered necessary for work performance.

Importance: The creation of robust maternal-embryonic interactions and implantation models is important for comprehending the early stages of embryonic development and reproductive disorders. Traditional two-dimensional (2D) cell culture systems often fail to accurately mimic the highly complex in vivo conditions. The employment of three-dimensional (3D) organoids has emerged as a promising strategy to overcome these limitations in recent years. The advancements in the field of organoid technology have opened new avenues for studying the physiology and diseases affecting female reproductive tract. Observations: This review summarizes the current strategies and advancements in the field of 3D organoids to establish maternal-embryonic interaction and implantation models for use in research and personalized medicine in assisted reproductive technology. The concepts of endometrial organoids, menstrual blood flow organoids, placental trophoblast organoids, stem cell-derived blastoids, and in vitro-generated embryo models are discussed in detail. We show the incorportaion of organoid systems and microfluidic technology to enhance tissue performance and precise management of the cellular surroundings. Conclusions and Relevance: This review provides insights into the future direction of modeling maternal-embryonic interaction research and its combination with other powerful technologies to interfere with this dialogue either by promoting or hindering it for improving fertility or methods for contraception, respectively. The merging of organoid systems with microfluidics facilitates the creation of sophisticated and functional organoid models, enhancing insights into organ development, disease mechanisms, and personalized medical investigations.
