Objective: The aim of this study is to suggest the standard of the direction sign on the pendant switch of overhead cranes which can reduce human errors in control. Background: A great number of crane accidents occur in industries. One of the major causes of the accidents is the mistake in the control of cranes by confusing the orientation of crane movements. Nevertheless, three different direction sign styles, 'East, West, South, North (EWSN)', 'Forward, Backward, Left, Right (FBLR)', and arrows for four directions are used without standardization. Method: An overhead crane simulator was installed for a laboratory experiment. It could move along six directions by the control of a pendant switch. 90 participants were evenly assigned to the three different conditions of direction sign styles. The participants were asked to control the pendant switch according to the continuously appearing 16 direction signs on a monitor ahead. The participants were allowed to refer an orientation sign board on the ceiling representing correct movement directions of the overhead crane simulator. Results: The direction sign style, 'EWSN', showed statistically significant better performance in task completion time and number of errors than the other sign styles. The direction sign style, 'EWSN', adopting the cardinal direction system, made the participants clear in direction controls after customizing to the crane movements. However, the direction sign styles, 'FBLR' and the arrows adopting the relative direction system made conflicts in direction controls due to the egocentric view of human. Conclusion: The direction sign style, 'EWSN', is the most appropriate for the standardization of the direction sign on the pendant switch of overhead cranes. Application: The results of this study can be applied to the standardization of direction sign in the legal notification on the safety certifications of crane manufacturing.

We evaluated the sanitation management practices in food delivery companies that supply food and food ingredients to school food-service establishments. We examined the practices 38 food delivery companies located in the Daegu and Gyeongbuk areas of Korea. Sanitation management practices were self-evaluated using a Likert 5-point scale. The total mean score for delivery company sanitation performance was 4.45. Scores for perceived sanitation management performance of the delivery companies were: food ingredient storage and management (4.47); delivery worker (4.47); and management of delivery van (4.38). The personal hygiene score was significantly higher than those of other sanitation inspection items evaluated (p<0.05). Delivery company managers believed that their sanitation management programs kept food hygienically and that the food was delivered to a high level of safety and at optimal quality. However, the managers thought that food quality standardization was needed to ensure transparency in delivery. Food delivery companies wish to obtain sanitation and supply certifications if they meet certain criteria.

The importance of the personal information has been increased, there have been a lot of efforts to establish a new policy, certification or law for administrating personal information more effectively and safely. Korean government has operated ISMS and PIMS certification system to assess whether an organization has established and managed appropriate information security system or not. However, it has been addressed the needs for revising and modifying of PIMS and ISMS. It is evaluated there are a few overlapped criteria to assess information management system in both ISMS and PIMS. ISMS-P certification, combining with ISMS and PIMS, is, finally, suggested, in the recent. GDPR is established having an aim of primarily to give control to individuals over their personal data and to simplify the regulatory environment for international business by unifying the regulation within the EU. This study compares GDPR and ISMS-P, focusing on "personal information". It can be expected to contribute as followings. This study can be a criterion for self-evaluation of possibility to violate of GDPR of a firm in preparation for ISMS-P. Second, this study also aims to increase the understanding of the role of ISMS-P and GDPR, among various certifications with the purpose of assessment of the information security management system, by reducing the costs required to obtain the unnecessary certification and alleviating the burden.

The purpose of the present study was to generate a list of business ethics components according to business area for small and medium-sized fashion companies. Based on the literature review, 21 components of business ethics components were identified within five business areas. Ten CEOs(Chief Executive Officers) each participated in an in-depth interview, sharing ethical and unethical cases from their own businesses. Constant comparative analysis was used to generate important business ethics components from those cases. In results, important business ethics components for each business area are: 1) using human-friendly materials, strengthening sustainable technologies, using vegan materials, concerning safe process, and reducing waste in the material production and sourcing area, 2) enhancing an efficiency in design, developing recycle/reuse designs, avoiding to copy designs, and using messages for public interest in the product design area, 3) concerning fair-trade, reducing harmful substance, saving energy, and using ethical supply channels in the distribution and logistics area, 4) acquiring certifications, promoting consumer protection, avoiding exaggerative/false advertisements, and promoting social contributions in the management and marketing area, and 5) promoting workers' rights, complying with the law, and investing on employee educations in the labor management area. All of the ethical and unethical cases of the ten companies have involved aspects of the 21 components, thereby enhancing understandings on how each issue is being seriously considered and/or handled in the small and medium-sized fashion companies. Study findings may provide a basis for development of a research model for quantitative studies and/or educational programs related to business ethics in the fashion industry.

With the increasing obligation to reduce greenhouse gas emissions to the building sector, the government has been gradually expanding its obligation to zero-energy buildings since 2020. Since the ZEB certification took effect in 2017, 48 preliminary and main certifications have been completed as of March 2019, and most of them are public buildings or even certified, but have earned Grade 5 of ZEB. This means that compared with the number of annual building permits registered in Korea, the figure is insignificant, and that it receives little if not mandatory. Therefore, this study investigated empirical cases of ZEB additional construction cost and conducted cost benefit analysis according to changes in ZEB additional construction cost based on a preliminary feasibility analysis project recently conducted by the KDI. In addition, considering the public buildings, the social costs were considered, and the cost-benefit analysis method was the same as the KDI's preliminary feasibility analysis method. The analysis shows that if the ratio of ZEB additional construction cost is more than 5 percent, it is analyzed that there is no economic feasibility, and considering that the ratio of additional construction cost in the cases of ZEB in Korea is 17 percent to 38 percent, it will not be easy to obtain ZEB certification in terms of cost. Finally, to narrow these differences in cost and economic aspects, the overseas low energy and ZEB incentive examples proposed measures such as the concept of subsidy payment in Illinois and the compensation of social costs to private ZEB.

The purpose of this study was to convergently investigate the perception of home-visiting music therapy services. For this, a survey was conducted on 74 persons divided into two groups, which are pre-service music therapists attending the graduate schools of music therapy and professional music therapists with certifications. As a result, first, the awareness of home-visiting music therapy service was lower than that of preexisting home-visiting services, but the necessity and expected effect were similar to them. Second, in the operational plans, there was shown a higher ratio of 40-minute services twice a week held by governmental or public organizations. Third, there were significant differences in subitems of trends and expected effects of the home-visiting music therapy service according to whether or not to hold a certification and to have experiences in providing the services. This study could be expected to provide basic data for the home-visiting music therapy being utilized as a field of music therapy. Based on the study, the establishment of practical service strategy could be suggested.
