The purpose of this study is to investigate industrial safety and health experts' opinions on the examination system of WMSDs(work related musculoskeletal disorders) risk factors. For doing this, a questionnaire study and two FGIs(focused group interview) were conducted. A questionnaire with open questions about the examination system was developed, and sent to 42 experts consented bye-mail. Of the experts, 24 experts responded, whose data were used in the analysis. The FGIs were performed for the persons in charge of industrial safety and health in industries and ergonomists. The questionnaire study revealed that most experts(91.3%) agreed with legalization of employers' duty for preventing WMSDs, necessity of the 11 tasks designated by Ministry of Labor, the examination system and ergonomics program, and pertinency for the examination system classification of periodic and occasional one. However, more than half experts disagreed with timeliness and appropriateness of the legal system. This was validated by the low approval rates for appropriateness of the 11 tasks, methods of the examination, charge person in the examination and ergonomics program. FGIs showed that it was desirable for the examination system to be legalized, and that the system was generally properly performed. It was suggested that the system be partially revised with reflecting problems disclosed during its enforcement rather than whole revision. It is expected that when revising relevant legal system, the results of this study would be used as valuable data.

Purpose : Accumulation of accurate data regarding the use and adequacy of subsidies is important to provide optimal development rehabilitation services. However, no reports have discussed the status regarding the use and adequacy of subsidies available for motor development rehabilitation as a part of development rehabilitation services in children and adolescents with cerebral palsy. In this study, we investigated the current use and subsidy adequacy of motor development rehabilitation as an essential part of development rehabilitation services in children and adolescents with cerebral palsy. Methods : The study included parents of children and adolescents with cerebral palsy, who underwent motor development rehabilitation of development rehabilitation services (n=148). The participants were administered a questionnaire to investigate the current use and subsidy adequacy of the motor development rehabilitation part of development rehabilitation services. Results : Most respondents indicated that 310,000-410,000 /month was an appropriate subsidy and agreed that the subsidy should be extended to adults with cerebral palsy. We observed a significant difference in the appropriate subsidy based on age groups (p=.029), as well as type of development rehabilitation service most needed (p=.005) and whether or not agree to extend the subsidy to adults according to gross motor function classification system level (p=.015). There were significant relations of appropriate subsidy (p<.001) and appropriateness of copay (p=.004) according to degree of transportation cost burden. Moreover, there were significant relations of appropriateness of current subsidy (p=.015) and appropriate subsidy (p<.001) according to degree of inconvenience of using transportation. Conclusion : This study highlights the need to increase subsidies for motor development rehabilitation of development rehabilitation services and that the subsidy should be determined based on the burden of transportation costs and the inconvenience of using transportation. Development rehabilitation service for adults with cerebral palsy should also be supported.

In the present study, a multicriteria decision-making (MCDM) problem of ranking of important radionuclide release scenarios in a low and intermediate radioactive waste repository is to treat on the basis of non-additive fuzzy measures and fuzzy integral theory. Ranking of important scenarios can lead to the provision of more effective safety measure in a design stage of the repository. The ranking is determined by a relative degree of appropriateness of scenario alternatives.(omitted)

This study aims to give practical help to the pattern making of baggy pants produced in large quantity from industrial fields. The functionality of crotch part is a key element to decide wear sensation and comfort of pants as having direct influence on movements of legs in pattern designing of baggy pants. The industrial patterns of baggy pants in various styles that are released currently in Korea were collected and a comparative analysis was conducted on them for the thesis. First, samples of men baggy pants were collected from three different brands and compared the completion sizes. Secondly, it studied the most appropriate patterns as quantifying the appropriateness of movements through fitting tests. Finally, the study verified the differences of visual images by surveys of professional groups. The conclusions obtained from this research are as follows. In terms of aesthetic attribute among the three brands, A baggy pants, which had a small size tolerance, were the most appropriate. Meanwhile concerning the appropriateness of movement, B baggy pants were shown to be the most appropriate. This reveals explicitly the problem of aesthetic attribute and functionality, which are always in conflict during the pattern design. It is necessary to develop patterns and establish a measurement system that may satisfy both of these factors.

This study examines whether employees' legitimacy perceptions of corporate social responsibility (CSR) affect their organizational citizenship behavior (OCB). It also investigates whether CEO's visionary leadership can moderate this causal relationship. CSR legitimacy is defined in the current study as employees' personal beliefs about the appropriateness of corporate CSR activities. In fact, employees evaluate the appropriateness of CSR activity based on its consistency with corporate philosophy (e.g. corporate mission, vision, and values) which functions as employees' referencial belief structure. If CSR activity is perceived as one of firm's effort to fulfill its mission, vision, and values, which means that espoused theory and theory-in-use of CSR activity are congruent, employees will consider firm's CSR activity as legitimate. If, however, employees think that CSR activity is not congruent with firm's mission, vision, and values, which means that espoused theory and theory-in-use of CSR activity are inconsistent, they will perceive that CSR activity of their firm is not legitimate. In the current study, we propose that employees who perceive that the CSR activity of their firm is legitimate are more likely to engage in OCB. In addition, we hypothesize that CEO's visionary leadership can strengthen the positive effect of employees' perception of CSR legitimacy on their OCB. We tested these hypotheses with the sample of 383 employees from 32 companies listed on DJSI (Dow Jones Sustainability Index) Korea 2009. We employed the HLM (hierarchical linear modeling) program to decompose the multi-level random effects. We found that CSR legitimacy perceptions of employees increase employees' OCB and that CEO's visionary leadership moderates this relationship. We discussed implications of these findings in more detail.

PURPOSES : This study aimed to evaluate the appropriateness of safety with the standard for threshold zone luminance as specified in the Recommendation for Lighting of Traffic Tunnel, which has been widely adopted worldwide. METHODS : A driving test of the subject in a full-scale road tunnel was conducted. The adaptation luminance and threshold zone luminance, which should be known for the driver to perceive an object within stopping sight distance, were obtained. These values were compared with the adaptation luminance and threshold zone luminance obtained by the existing reduced model test and tunnel lighting standard that has served as a guideline for the current threshold zone luminance standard. RESULTS : According to this study, threshold zone luminance should be increased to at least 1.8 times the value proposed in the existing studies and to twice the domestic tunnel lighting standard (KS C 3703: 2014). CONCLUSIONS : The threshold zone luminance proposed in this study differs largely from that obtained from indoor tests and from the current tunnel lighting standard used worldwide; this difference may be attributed to the fact that the indoor tests did not incorporate driving workload, non-uniformity of luminance distribution in terms of sight, and factors that reduce the visibility of the driver, such as the light reflected into the driver's eyes. Hence, it is necessary to further review the factors that reduce the visibility of drivers approaching tunnels in order to determine the rational tunnel threshold zone luminance.

Background: Piperacillin/tazobactam (TZP) is an antibiotic against a broad spectrum of gram-positive, gram-negative, and aerobic and anaerobic strains of bacteria. Due to changes in its pharmacokinetic and pharmacodynamic parameters by TZP-treated patients' renal functions and obesity, it is important to administrate and monitor TZP based on their renal functions and Body Mass Index (BMI) levels. The purpose of this study was to determine the appropriateness of administration doses of TZP based on renal functions of obese cancer patients in a tertiary hospital. Methods: This study was retrospectively conducted with obese cancer patients with $BMI{\geq}30kg/m^2$ in a tertiary hospital, Korea from September 2004 to August 2014. Data were collected through Electronic Medical Record (EMR) which contained laboratory data and TZP dosing of each patient. Results: Among 7,058 patients during the study period, 102 prescriptions were selected based on inclusion and exclusion criteria and classified by their renal functions. Although TZP should be used based on patients' renal functions to adjust its dose, its initial dose and dosing interval were consistently used without considering patients' renal functions on a regular basis. Especially, in the comparison with FDA dosing standard of TZP, approximately twice patients with $20mL/min{\leq}CrCl{\leq}40mL/min$ received domestically 4.5 g instead of 2.25 g as the TZP starting dose. Conclusion: The appropriate doses of TZP were administered to almost all of obese cancer patients; however, the recommended TZP dose was different between Korea and other countries by twice the amount. Further related studies are necessary to clearly determine the results, to optimize TZP treatment for obese patients with cancer in clinical practice, and to design and develop new TZP formulations for them in pharmaceutical industry.
