The purpose of this study is to enhance the understanding of consumer experience and behavior of Internet of Things (IoT) services and to provide practical implications through investigating the impact of benefits-cost factors and network externalities on consumers' adoption intention of IoT services. An online survey was conducted on general consumers in their 20s to 60s who were aware of the IoT services and 328 data were collected. Using SPSS 24.0, frequency analysis, correlation analysis, factor analysis, and hierarchical regression analysis were conducted. As a result, the level of consumers' IoT service experience in various contexts was examined, and entertainment, informativeness, loss of humanity, compatibility, and complementarity were found to have a significant effect on consumers' adoption intention of IoT services. This study suggests that strengthening network externality effects by increasing compatibility and complementarity is important in promoting consumers' adoption of IoT services. In future studies, it is necessary to adopt specific Internet of Things services to verify the validity of the models developed in this study.

This study aims to examine the intermediary roles of employee performance between high performance work system (HPWS) and its operational performance on the resource based view. Taking into account the unit of analysis, this study used a hierarchical linear modeling analysis in order to test rigorously the association between HPWS at the organisational level and employee performance at the individual level. For this empirical test, Human Capital Corporate Panel (HCCP) data including 316 firms and 7,872 respondents (including 923 team leaders) were used. To meet the unit of analysis and test the mediation effect, data at the individual and team level were aggregated into the organisational level. The empirical results show that HPWS have a positive impact on operational performance as well as employee performance such as job satisfaction, organisational commitment and organisational trust. Regarding the mediation effect, job satisfaction and organisational trust mediate between HPWS and operational performance. Theoretical implications are discussed in conclusion.

This study examined the effects of self-critical perfectionism on organizational citizenship behavior (OCB) and the moderating effects of gender in the relationship to understand deeply the dilemmatic situation resulting from OCB at the individual level. In other words, based on the conservation of resources theory, this study examined how self-critical perfectionism influences the OCB and how gender moderates the relationship between self-critical perfectionism and OCB. More specifically, this study predicts that self-perfectionism will be negatively related to OCB. Furthermore, this negative relationship between self-critical perfectionism and OCB will be strengthened in men compared to women. To test these hypotheses, the supervisor-subordinate survey was conducted, and 150 dyad data were analyzed. The analytical results of HLM (Hierarchical Linear Modeling) showed that self-critical perfectionism negatively influenced the OCB, and this negative effect was strengthened in men compared to women. This paper suggests implications and limitations for the literature on OCB.

The purpose of this study is to identify the relationships among childcare teachers' emotional intelligence, daycare center directors' emotional leadership, and teacher-infant interactions. Also, this study examines whether a daycare center director's emotional leadership would mediate the correlation between a childcare teacher's emotional intelligence and teacher-infant interactions. A questionnaire was given to 293 childcare teachers. Using SPSS version 21.0, the data were analyzed for Pearson's correlation, hierarchical regression analysis, the Sobel-test, and the meditation effect proposed by Baron and Kenny. The findings are as follows. First, there was a positive correlation between a childcare teacher's emotional intelligence, the director's emotional leadership, and teacher-infant interactions. Second, the influence on teacher-infant interactions from directors' emotional leadership was relatively greater than childcare teachers' emotional intelligence. Finally, the emotional leadership of daycare center directors partially mediated the relationship between childcare teachers' emotional intelligence and teacher-infant interactions. This study provides significant empirical data for improving childcare.

This descriptive survey study identified the factors influencing the abiliy of healthcare perceived by high school students. The survey was conducted from May 7, 2020, to Sep. 17, 2020 for 119 high school students in City D. SPSS WIN 22.0 program was used to for t-test and one-way ANOVA with Pearson's correlation coefficients and hierarchical regression analysis. The ability of healthcare perceived by high school students had a static correlation with the sub-domains of family function, that is, family cohesion(r=.65, p<.001) and family adaptability(r=.54, p<.001). For male students(β=.17, p=.012), those who reported a high level of perceived health status showed a high level of ability of healthcare(β=.25, p<.001). Significant influencing factors on high school students' health management ability were identified as gender (β=.17), their own health status perception (β=.23), and family cohesion (β=.45), and the explanatory power of the model was 50%. appear. Further research is hereby suggested for validation of the mediating role and effects of health care education programs to improve the family function perceived by high school students, encourage their practicing of health care management and help them to enter into healthy adulthood.

Only a few studies have investigated the influence of career calling on career adaptability and the mechanisms behind this relationship, so this investigated how the search for and presence of meaning, the two elements of meaning in life, affect this relationship. 247 Participants completed a survey on career calling, career adaptability, the search for meaning and the presence of meaning. Correlational analysis was conducted to examine the relationships between the research variables. A serial multiple mdediating effects test was conducted to test the proposed mediating effects. Finally, a bootstrapping procedure was used with SPSS Macro to test the significance of the indirect effects. The results were as follows: First, career calling was positively related with career adaptability. Second, the search for and presence of meaning both partially mediated the relationship between career calling and career adaptability. This result implies that the search for meaning alone can lead to positive outcomes, such as increasing career adaptability, a result not found in previous studies. Third, the relationship between career calling and career adaptability was sequentially mediated by the search for meaning and the presence of meaning. This paper ends with a discussion of implications of this study's results in clinical practice and this study's limitations.

The aim of this research was to develop a climate change vulnerability index at the district level (Si, Gun, Gu) with respect to the health care sector in Korea. The climate change vulnerability index was esimated based on the four major causes of climate-related illnesses : vector, flood, heat waves, and air pollution/allergies. The vulnerability assessment framework consists of six layers, all of which are based on the IPCC vulnerability concepts (exposure, sensitivity, and adaptive capacity) and the pathway of direct and indirect impacts of climate change modulators on health. We collected proxy variables based on the conceptual framework of climate change vulnerability. Data were standardized using the min-max normalization method. We applied the analytic hierarchy process (AHP) weight and aggregated the variables using the non-compensatory multi-criteria approach. To verify the index, sensitivity analysis was conducted by using another aggregation method (geometric transformation method, which was applied to the index of multiple deprivation in the UK) and weight, calculated by the Budget Allocation method. The results showed that it would be possible to identify the vulnerable areas by applying the developed climate change vulnerability assessment index. The climate change vulnerability index could then be used as a valuable tool in setting climate change adaptation policies in the health care sector.
