Objectives: Receive Operating Characteristic(ROC) curve with the area under the ROC curve(AUC) is one of the most popular indicator to evaluate the criterion validity of the measurement tool. This study was conducted to develop a standardized questionnaire to discriminate workers at high-risk of work-related musculoskeletal disorders using ROC analysis. Methods: The diagnostic results determined by rehabilitation medicine specialists in 370 persons(89 shipyard CAD workers, 113 telephone directory assistant operators, 79 women with occupation, and 89 housewives) were compared with participant's own replies to 'the questionnair on the worker's subjective physical symptoms'(Kwon, 1996). The AUC's from four models with different methods in item selection and weighting were compared with each other. These 4 models were applied to 225 persons, working in an assembly line of motor vehicle, for the purpose of AUC reliability test. Results: In a weighted model with 11 items, the AUC was 0.8155 in the primary study population, and 0.8026 in the secondary study population(p=0.3780). It was superior in the aspects of discriminability, reliability and convenience. A new questionnaire of musculoskeletal disorder could be constructed by this model. Conclusion: A more valid questionnaire with a small number of items and the quantitative weight scores useful for the relative comparisons are the main results of this study. While the absolute reference value applicable to the wide range of populations was not estimated, the basic intent of this study, developing a surveillance fool through quantitative validation of the measures, would serve for the systematic disease prevention activities.

This study empirically investigated the relationship among knowledge transfer, network(firm network and government network) and performance Korean MNCs' subsidiaries in terms of absorptive capacity and entry mode roles in China. For this, absorptive capacity was established as an independent variable, mediating variable, and moderating variable. And the entry mode was divided into single investment and joint venture and set to the moderating variable. Data for the analysis of actual proof was randomly selected from the companies which was established more than 3 years before KOTRA 'The overseas expansion Korean company directory (2014)'. Questionnaires to 138 Chinese subsidiaries of Korean MNCs were collected by FAX and E-mail. AMOS was utilized and collected data investigated the role of the absorption capacity and entry mode as the covariance structure analysis. The empirical analysis showed that absorption capacity has a direct influence on management performance as an independent variable with the network (firm network and government network). It only has a partial mediating role between enterprise networks and management performance, and no meaningful result was gained as its moderationg role bewteen the exogenous variable and management performance. And in terms of Korean companies' moderating role in entering China, they have a moderating role between government network, absorption capacity and management performance, but did not show a statistically significant result between knowledge transfer, enterprise network and management performance. Absorption capacity, as the variable affecting overseas subsidiary's management performance, should not be considered a mediating or moderating variable, but an independent variable. Since the joint venture is showing higher performance than single investment when going into the Chinese market, implication is provided for options in overseas expansion. But this research has the limitation in generalization because it is aiming at the subsidiaries of the Korean company investing in China. Therefore, it is more desirable in the future to conduct a study of the subsidiary of the Korean company entering several countries. It also has limitations in generalization, because the research was conducted using a limited number of variables, despite there are various factors affecting the management performance of Chinese subsidiaries.

The implementation of the "Basic Law on Korean Heritage" on May 17, 2024, brought about significant changes in the operation of Korean heritage-related ordinances in 17 local governments. This study specifically analyzes the production, collection, and information transfer of Korean heritage information between the Korean Heritage Service and local governments, focusing on the provisions of the law. Finally, in order to achieve the goal of revitalizing the management of Korean heritage information, the study suggests five directions for improvement of the local government ordinance from three perspectives. Firstly, in order to systematize the production of Korean heritage information, it is necessary to specify the entities that produce and manage information in Korean heritage, and to select important Korean heritage information from the information produced and manage it strategically. In today's complex Korean heritage management environment, it is impossible to manage all the Korean heritage information produced by various stakeholders. Secondly, in order to systematize the delivery of Korean heritage information, detailed procedures related to the information to be delivered to the Korean Heritage Service should be specified, and a clear plan for information delivery and management between local and basic local governments should be defined. In the Korean heritage information delivery system, local governments play various roles as direct information providers, managers, consumers, and transmitters. Therefore, it is necessary to specify the provisions of the ordinance so that local governments can systematically fulfill their various roles in the Korean heritage information delivery system. Thirdly, in order to activate the production of Korean heritage information, local governments should review the provisions of the Act to ensure that important Korean heritage information generated from directory provisions and non-mandatory provisions, in addition to the mandatory provisions of the Korean Heritage Act, is not omitted. In particular, Korean heritage information is not just administrative information, but also includes specialized information for the maintenance of the current state of Korean heritage. Therefore, if certain Korean heritage information is partially missing, there may be a gap in intergovernmental communication for Korean heritage management.
