This paper presents a model for the Minimum Wage Commission's decision process and analyzes the strategic actions of the participants in the process. The Minimum Wage Commission has used two ways of setting the minimum wage. The commission has voted either on the labor's against the management' final proposals or has voted on the public interest commissioners' proposal. According to the model, the minimum wage is determined at a level that is very close to or at a level preferred by the median voter among the public interest commissioners. But the probability of adopting labor or management proposal is ex-ante the same. Empirical evidence from the minimum wage decision process is consistent with the predictions of the model. The probability of adopting the labor's proposal in the minimum wage commission voting is not statistically significantly different from 50%. The model also suggests that the preference of the median voter among public interest commissioners determines the minimum wage level. Since the government appoints public interest commissioners and thus, in fact, the median voters, the government can decide the minimum wage level. This proposition is also consistent with data. The annual growth rate of the minimum wage under the progressive governments is higher than under conservative governments.

From the past to the present, justice has attracted many people's attention. Most of the previous studies carried out in relation to justice are studies of the resulting variables, and there is a great advantage that they let us know about the importance of justice. However, the findings are focused only on the behavior of the members of the organization according to the status of justice already perceived. Therefore, studies on the antecedent of justice are also necessary to understand justice accurately. This study identifies the factors that can directly affect justice and the contextual factors that could moderate their relationship. In particular, using the '2017 Public Employee Perception Survey' released by the Korea Institute of Public Administration, we examined how innovative behavior of public employees affects the perception of distributive justice and how the relative professionalism, which is the situation variable, moderates the relationship between variables. A regression analysis of 321 public employees showed that innovative behavior affects the perception of distributive justice, and that the positive relationship of innovation behavior to the perception of distributive justice is weakened when the level of individual perceived relative professionalism is high.

National industrial complexes, airports, and seaports are major logistics nodes and the availability of their logistics services is a key factor for the successful operation of entire supply chains. For this reason, the central government has established a plan for their development and is investing in development projects. However, some difficulties exist in project prioritization and investment plan creation owing to the absence of a clear appraising method. For a smooth flow of national logistics and efficient investment on facilities, it is necessary to diagnose the logistics facilities' present conditions and practice sustainable management. In this study, a diagnostic method for logistics services, which consists of service factors and facility factors, is proposed. Adopting the method, facility factors can be prioritized to improve facilities' services; further, a standard procedure is proposed to support decision making for effective investments in logistics facilities. The method is applied to actual logistics facilities (three national industrial complexes, three seaports, and two airports) and the results indicate that it can be effectively applied to actual logistics facilities.

This paper attempts to explore the impact of technological regulation on technological innovation and performance of Small and Medium Enterprises(SMEs) by analysing a survey data of 286 Korean SMEs. The 3-step mediated regression analysis results reveal that the perceived regulatory burden is negatively associated with SMEs' R&D investment and innovation of product and process. Moreover, the level of regulatory burden may affect the objective and subjective performance of SMEs. The results suggest that regulatory policies for reducing regulatory burden need to be designed and implemented in order to enhance technological innovation and performance of SMEs.

In this study the possibility of hydrogen as a fuel in a small-sized two-stroke SI (Spark ignition) engine was investigated. For this purpose, experimental setup including an engine, a dynamometer, equipments for hydrogen and lubricant oil supply was prepared. And then preliminary experiments for the hydrogen-fueled engine combustion were conducted. In the case of hydrogen-fueled engines comparing to gasoline backfire occurs when the excess air ratio is lower than a specific value. This can cause engine power reduction and damage to the engine parts. The engine was controlled to operate at lean conditions to prevent backfire. Through the control of excess air ratio, the maximum engine brake power output of 3 kW was achieved in a 210 cc engine, while it was 6 kW in case of gasoline fuel.

This study explored the moderating effects of task difficulty for flow, learning motivation, and interesting in distant PBL classes of pre-service teachers. For this, the research model was constructed by analyzing previous studies. The research model verification was conducted by 105 students of taking courses in the curriculum. The distant PBL used a real-time video conference system. Cooperative activities were carried out in real time. After the end of the distant PBL activity, the level of learning motivation, interesting, flow, and task difficulty perception were measured. The collected data were analyzed using a test of the structural model invariance across the groups using a structural equation model. This analysis verifies the difference in path coefficients between measurement models. The control effect of task difficulty was verified through the difference in path coefficient. As a result, it was verified that interesting mediates the influence of learning motivation on flow. And the moderating effect of the perceived task difficulty appeared on the path from learning motivation to interesting.

Financial service chatbots are hindering user experience with conversational errors and machine-like responses. This study aims to examine the effect of self-disclosure and emotional expression of an anthropomorphic chatbot on user experience before conversation errors occur in financial services. In financial inquiries, scenarios were designed based on self-disclosure type (positive vs. negative) and emotional expression level(high confident vs. low confident), and online experiments were conducted. The result revealed that when anthropomorphic chatbot provided self-disclosure and emotional expression, the main effect has been shown on trust, annoyance, service recovery, and intention to continuous use. In addition, interaction effects were significant in trust and annoyance. In conclusion, this paper demonstrated that anthropomorphic chatbot's positive self-disclosure and confident emotional expression influenced trust and annoyance.

This study is aimed to verify the impact of health literacy on communication competence in nursing students. 104 nursing students participated in this descriptive research with an online self-reported questionnaire from May 3 to 21, 2021, at a university located in G city. The data were analyzed by two-sample t-test, ANOVA and hierarchical regression with SPSS program. The score of health literacy was 48.62/66 and the communication competence was 59.60/75. More than half perceived that the average reading level of Korean adults was higher than the actual. subjective health status(β=.309, p<.001), health literacy(β=.284, p=.002) and subjective academic grade(β=.235, p=.009) had significant influence on communication competence in the nursing students(F=10.546, p<.001). The explanatory power increased 7.3% more by adding health literacy(F=10.339, p=.002). To enhance communication competence of nursing students, more systematic curriculums to improve health literacy are needed.
