The purpose of this study is to analyze the causal relationship, in the perspective of Total Quality Management, among the education quality factors, which were suggested in the previous researches. Lee et al. [16] had tried to analyze the relationship among education factors, but they did not estimate the education factor using latent variable concept, which is very reasonable and efficient to represent the constructed concepts. So this study attempts to analyze the causal relationship among education quality factors, represented as latent variables used in structural equation modeling (SEM), and compared with each other. In this study, education quality factors were measured by several measures, constructed as several latent variables, and then processed with AMOS, the most efficient statistical package in the SEM area. In order to analyze the causal relationship among the education quality factors constructed as latent variables, this study designed the structural equation model with suggested factors and established several research hypotheses. This study discovered a prominent causality among the education quality factors, such as education leadership, student scholastic performance and satisfaction of education quality, which is similar to that of previous research. This outcome is really a unique Korean syndrome manifest within our educational career orientation.

This study investigated highschool students' brain waves on functional tasks such as a transition(F task) from equation to graph and the other transition(G task) vice versa. A total of 39 students participated in the study who attended a high school located in Gyunggi province. These students were divided into two groups, HMA and LMA by MASS test revised by Ko, & Yi (2012). The functional tasks for the stroop task to measure EEG were provided from a previous study, Seok(2015). The results indicated two groups on G tasks showed deeper and wider brain waves which demonstrated G tasks were more difficult than F tasks. However, HMA group had an effect of the non-psychological program which had given more chances on G tasks rather than F tasks within Students' Zone of Proximal Development. Also, HMA group's brain waves had more ranges in amplitude and width of waves. These results imply that the characteristics of students' brain waves with math anxiety are consistent to the previous studies.

As migraine pain represents a substantial personal and social burden worldwide, there has been a great deal of effort in developing a screening instrument for migraine. Lipton et al(2003) developed and validated the ID Migraine questionnaire, which is a self-administered screener for migraine in primary care, and it is brief and easy to use for a primary care provider. The aim of this study was to determine if the ID Migraine questionnaire could be applied successfully to assess the headache patients with temporomandibular disorders(TMD) and orofacial pain. This study found that nausea, photophobia and headache-related disability had the highest individual sensitivities and specificities, and the performance of the three-item screener was equivalent to that reported in a previous study. Although the sensitivity of the three-item screener in this study (0.58) was lower than in a previous study (0.81), the specificity (0.98) was higher and the positive predictive value was 93.9%. This suggest that the ID Migraine questionnaire is very efficient in this setting. In conclusion, the ID Migraine questionnaire, which is a three-item screener consisting of nausea, photophobia and headache-related disability, is effective as a self-administered report for detecting migraine headaches in patients with temporomandibular disorders(TMD) and orofacial pain.

Purpose: The aim of the present study was to investigate the effects of proprioceptive neuromuscular facilitation (PNF) and taping interventions on balance ability, joint position sense, and ankle joint strength. Methods: Thirty subjects who had experienced an ankle sprain within the previous 3 months participated in this study. The subjects were randomly assigned to a PNF group (n=15) or a taping group (n=15). Before and after the interventions, ankle dorsi-flexion and plantar-flexion strength, joint position error, and total center of pressure movements in one leg while in a standing position were measured. Results: Regardless of the group allocation, ankle dorsi-flexion and plantar-flexion strength significantly improved after the interventions (p<0.05). Compared to preintervention measurements, joint position errors were significantly reduced postintervention (p<0.05). The PNF intervention significantly decreased the total lateral movement of the center of pressure in the one leg standing condition (p<0.05). Conclusion: Both PNF and taping interventions improved joint position sense and ankle joint strength. In common with the findings of a previous study, the PNF intervention improved balance ability. Further study is required to investigate the effects of various PNF and taping interventions on ankle performance in subjects with chronic ankle sprains.

Performance evaluation continues to receive attention today as it has for the past few decades. The problem addressed in this paper concerns the relationship between supervisor's causal attributions and their subsequent responses behavior. Previous study in personnel and other disciplines has indicated the importance of causal attributions in the interpretation of poor performance. However, most study has focused on antecedents of attributions than supervisor's responses to the subordinate's poor performance. The objective of this study was to investigate the effects of supervisor's causal attributions and subordinate's responses to a subordinate's poor performance. Specifically, using in the public sector context, the study examined the effects to two dimensions of causal attributions: locus of causality and stability, as well as on the punitiveness of supervisors's responses. The result supported that when the subordinate is internal causes for the performance failure, supervisor's responses were more punitive. Consistent with previous studies, internal attributions were found to result in more punitive behavior than external attribution. In addition, attributions to effort and luck were found to result in more punitive behavior than attributions to ability and task difficulty. Thus, the first hypothesis and second hypothesis supported. These result suggest the importance of appropriately for performance evaluation.

Recently, the concern of aging society is 'Healthy life' for the elderly and pre-elderly. Especially, realizing the 'Healthy life', it is very important for the elderly to establish living environment for holding and maintaining mental depression. Mental depression is related to dysfunction of sensory organ included physical functions. Therefore, the dysfunction of elderly's sensory organ is required to the guideline of environmental planning. In this study, among five senses, I focused visual sense due to the large proportion of environmental perception. The purpose of this study is to analyze the degree of geriatric depression and preference of simulated images applying preferable color for the elderly. This study conducted literature review and questionnaire survey. Firstly, the previous studies related with the melancholy, sense of isolation, self-regard for the elderly analyzed. Secondly, the questionnaire tool measuring the degree of geriatric depression developed. Thirdly, the tool investigating the preference for the simulated images applied main, sub, and accent colors produced. Applied preferable colors were used from the results previous study. Lastly, based on the result, the basic data of color planning were suggested. It was judged that this study is an useful as the basic guideline of color planning for the elderly's residential spaces and the potential value of considering geriatric depression and the color planning in terms of the elderly's visual sense.

The competitiveness of container terminals hinges on minimizing the time vessels spend in port and on schedule services. Many previous researches on container terminals have tried to optimize the equipment allocation plan and to improve the activity of resources. Nevertheless, there have been few researches conducted on yard tractors, which move containers between the quay and the yard. The aim of this study is to propose the use of Real Time Location Systems (RTLS) based Dynamic Planning for yard tractors. Only RFID (Radio Frequency Identification) tags, which are attached to yard tractors, are able to support RTLS implementation. The system can provide real time job ordering in terms of load balancing using the information on location, in regards to the movement of yard tractors. This study will present the practical feasibility of RTLS, which can ultimately reduce the congestion of Hot Queues in container terminals. As a result, container terminals can be more productive and competitive. In order to accomplish the purpose of this study, we examined previous studies on the competitiveness of container terminals and summarized the potential of RTLS using RFID. In addition, we identified the role of yard tractors and proposed the two rules of Dynamic Planning for the yard tractors. We then fulfilled computational experiments on how yard tractors carrying containers by RTLS ordering Finally, the benefits and the implications of this study are discussed.

Purpose - study aims to investigate the relationships between global value chain (GVC)- and transportation-related determinants and economic performance. Also, moderating effects of COVID-19 on the relationships are theoretically and empirically discussed. A limitation of previous studies includes their over-reliance on the opportunities of GVC participation and larger transportation. This study represents the challenges associated with them. Also, it shows how GVC and logistics can be difficult in case of a market fluctuation such as COVID-19. Design/methodology - The sample for this study includes 828 observations from 138 countries. A semi-panel data set has been used. Six observations for each country are used to empirically test the hypotheses and a Two-way cluster model is conducted. Findings - It is confirmed that GVC forward participation contributes more than the backward participation to enhance performance. Transportation infrastructure is critical, but large scales of marine and air transportations are not positive in terms of economic performance. Stricter government response to COVID-19 negatively moderates economic performance by GVC backward participation and transportation infrastructure. Originality/value - The spread of COVID-19 is causing a severe collapse of GVC and transportation. This study empirically verifies the moderating effects of the government stringency on GVC and transportation. Previous studies usually discuss a positive impact of GVC and transportation size on economic performance. However, this study aims to show various challenges behind GVC participation and large scale transportation.

Purpose This study is based on previous studies related to the function and operating system of the project management system for efficient project management. The purpose of the study is, first, to find out how the project performance is affected by the utilization of the project management system and the involvement of the PMO. Second, the mediating effect of implementing integrated management between the project management system and project performance is to be demonstrated. Design/methodology/approach Based on previous studies related to project management, this study designed a research model by integrating functional factors derived from project management system design studies, integrated management factors, and factors derived from PMO function studies. Findings As a result of the empirical analysis, this study first confirmed that high utilization of the project management system and high involvement of the PMO are factors that affect project performance. In addition, it was confirmed that the establishment of the system and the introduction of PMO do not guarantee project performance. Second, it was confirmed that the execution of integrated management has a mediating effect between the system and the project performance, and that the high utilization of the system has a positive effect on the mediating effect.
