The major aim of this study was to find out the influence of brand previous knowledge, previous brand attitude, perceived quality on VMD cognition and attitude. Eight brands were selected as experimental stimuli brands for this study. A total of 320 questionnaires were obtained from college students living in Daegu. Using factor analysis, each of brand previous knowledge, previous brand attitude, perceived quality, VMD attitude were extracted one factor.VMD cognition were divided into 5 factors; Coordination, Attractiveness, Fashionability, Fitness, and Functionality. The results revealed that previous brand attitude and perceived quality affected VMD cognition and VMD attitude, while brand previous knowledge did not affect VMD cognition and VMD attitude. Therefore, when companies related to fashion investigate the effect of VMD, they should consider the previous brand attitude and perceived quality of their brands.

This study aims to identify causal variables by examining the mutual influences of community consciousness and life satisfaction. We used some data of KCYPS. A longitudinal study of 1952 adolescents selected as a sample was conducted using the Aautoregressive crossover delay model. The results of this study are as follows: First, it showed that life satisfaction is consistently affecting the later life satisfaction with the passage of time. Second, community consciousness showed that the previous community consciousness has a constant influence on the subsequent community consciousness as time passes. Third, the effect of previous life satisfaction on community consciousness was significant. Therefore, the cross-delay effect of life satisfaction on community awareness was stable with time. In other words, life satisfaction level was a causal variable that takes precedence over community consciousness, and the higher the life satisfaction of the previous time, the higher the level of community consciousness in the future. Fourth, the cross-delay effect of community consciousness on life satisfaction was not significant because community consciousness at previous time had no meaningful effect on life satisfaction at later time, so consciousness of community at previous time affects life satisfaction. This study provided some implications basing on this results.

Green Standard for Energy and Environmental Design (G-SEED) is evaluates the eco-friendliness of the building as an abjective means. Study in green building is made actively, and is being developed through constant revision. However, study results of green building have not been fully reflected in the standard. Therefore, this study analyzes the previous studies about G-SEED and checks the reflection of requirements. This study will be a reference of future revision of G-SEED. Score of items are divided into low and high score items. These items should be reflected appropriately in the standard through the score adjustment. Some requirements proposed in previous studies was reflected, while substantial requirements was not reflected. Proposed improvement requirements are classed as to establish specific standards, strengthen standards, propose a new evaluation method to existing items, and add new items.

For reference human intrusion scenarios constructed in previous study, a probabilistic safety assessment to derive the radionuclide concentration limits for the low- and intermediate- level radioactive waste disposal facility is conducted. Statistical approach by the Latin Hypercube Sampling method is introduced and new assumptions about the disposal facility system are examined and discussed. In our previous study of deterministic approach, the post construction scenarios appeared as most limiting scenario to derive the radionuclide concentration limits. Whereas, in this statistical approach, the post drilling and the post construction scenarios are mutually competing for the scenario selection according to which radionuclides are more important in safety assessment context. Introduction of new assumption shows that the post drilling scenario can play an important role as the limiting scenario instead of the post-construction scenario. When we compare the concentration limits between the previous and this study, concentrations of radionuclides such as Nb-94, Cs-137 and alpha-emitting radionuclides show elevated values than the case of the previous study. Remaining radionuclides such as Sr-90, Tc-99 I-129, Ni-59 and Ni-63 show lower values than the case of the previous study.

Green Standard for Energy and Environmental Design(G-SEED) has been implemented for the realization of sustainable development and resource-saving and eco-friendly buildings from 2002. Studies about the green buildings are made actively and is being developed through constant revision. However, study results of green building have not been fully reflected in the standard. Therefore, this study analyzes the previous studies about G-SEED for school facilities and check the degree of to reflect the problems and improvements suggested in previous studies. This study will be a reference of future revision Substantial problems and requirements are not reflected in revision standard. Proposed improvement requirements are classed as to improve the items(establish specific standards, supplementation), strengthen standards(designate the prerequisite items), propose a new evaluation method, add new items. delete exist items and adjust the score. Therefore, future revision of G-SEED for school facilities should reflect the results of previous studies.

Background: Free-flap reconstruction for recurrent head and neck cancer may be challenging depending on the previous treatments, those are, chemotherapy, radiotherapy, and surgery, including neck dissection or free tissue transfer. Specifically, the previous treatment could compromise the neck vessels, thereby making free-flap reconstruction more difficult. This study aimed to investigate the correlation between previous treatments and vascular compromise of the free flap. Methods: In this retrospective study, 124 free-flap reconstructions in 116 patients for recurrent head and neck cancer between 1993 and 2017 were investigated. The demographic characteristics, previous treatments, flap choices, infections, recipient vessels, and vascular crises were evaluated. Results: Of the 124 reconstruction cases, 10 had vascular crises. There were six revisions, totaling six flap failures. The success rate of free-flap reconstruction for recurrent cancer was 95.2%, which significantly differed from that for primary cancer (98.8%, p= 0.006). Moreover, in the recurrent cancer group, no correlation was found between previous treatments and vascular crises (p> 0.05). Increased rates of contralateral or uncommon anastomoses were found following neck dissection (p< 0.05). Conclusion: Previous neck dissection or radiotherapy could lead to scarring and tissue damage, which could in turn make microvascular reconstruction more challenging; however, the effect was not definite in this study. Approximately 60% of patients with previous neck dissection had compromised ipsilateral recipient vessels, which resulted in contralateral or uncommon anastomoses. In this study, free-flap reconstruction seems to be quite safe and preferable in patients with recurrent head and neck cancer based on the overall survival rate.

Purpose - This study analyzes the effects that the response to the technical barriers to trade (TBT), which are used by various countries as means to restrict imports, exerts on exports at a time when protectionism is emerging in the face of a global economic downturn. TBT has been widely used in developed countries for the safety and protection of their people. Recently, the use of TBT as a tool of protectionism has increased considerably in developing countries as well. Therefore, this study analyzes the South Korean SMEs' response and export performance. Design/methodology - To analyze SMEs' response to TBT and their export performance, this study conducted empirical analysis through statistical analysis. To this end, the research established a theory based on previous research and designed its hypothesis and research model. To verify the hypothesis and research model, factor analysis addressing validity and reliability was performed using SPSS 25 and AMOS 26, and the structural equation model was analyzed. Findings - This study found the causal relationship between the independent variable, the mediating variable, and the dependent variable adopted against the theoretical background to have little or no effect, in contrast with previous studies. In a break from previous studies, all hypotheses were rejected for innovation strategic competencies, one of the sub-factors of the independent variable, which is believed to be a result of the lack of practical research related to TBT. Originality/value - Previous studies performed analysis using trade statistics or macro data. A number of such studies analyzed the relationship between technical regulation and trade volume. This study differs from previous studies in some respects, because it analyzed the export performance of companies by establishing a hypothesis and implementing a research model with the factors analyzed in previous studies. In addition, a new attempt has been made by classifying the TBT response factors into technology competencies, human resource competencies, and innovation strategic competencies, and utilizing technology innovation and the export support system as mediating effects.

For an undirected graph G=(V, E), the Rural Postman Problem (RPP) is a problem that finds a minimum cost tour that must pass edges in E'($\subseteq$ E) at least once. RPP, such as Traveling Salesman Problem (TSP), is known as an NP. Complete problem. In the previous study of RPP, he structure of the chromosome is constructed by E' and the direction of the edge. Hence, the larger the size of IE' I is, the larger the size of the chromosome and the size of the solution space are. In this paper, we transform the RPP into a Hamiltonian graph and use a genetic algorithm to solve the transformed problem using restructured chromosomes. In the simulations, we analyze our method and the previous study. From the simulation results, it is found that the results of the proposed method is better than those of the previous method and the proposed method also obtains the near optimal solution in earlier generations than the previous study.
