Construction industry has a relatively higher industrial accident rate than other domestic industries. Thus, to reduce the accident rate, researches on the methodology of worker's safety education combined with new technologies like IT technology have increased. In the light of workers' safety information provision, this study develops a VR(Virtual Reality)-based construction site using the BIM(Building Information Modeling) data. The target structures and geographical features are included in the VR-based construction site where the construction machinery model and worker model are also created using a game engine. For highly effective provision of safety information, video clips with suitable captions corresponding to working processes were made with proper screen directing. They should be appropriately connected to correct worker's operations to improve the work commitment level, sense of reality and inducement of interest. From this scenario, the 3D VR-based construction site, which can be experienced through a VR equipment, was created and in the same platform, the safety information was provided by the video clip combined with the suitable captions. Although the real construction site involves various requirements depending on field situation and the expertness and experience of workers are not consistent, the developed safety information provision based on the VR construction site is expected to effectively reduce the incomplete factors leading to construction accidents by improving the worker's perception of workplace safety.

This study examined the factors related to family caregiver satisfaction with institutional care services for beneficiaries under the Public Long-Term Care Insurance(PLTCI) system. Determining what contributes to family caregiver satisfaction is a critical step toward implementing effective quality improvement strategies. A national cross-sectional descriptive survey was conducted from November to December 2008, using proportionate quota sampling based on the location and level of Long-Term Care of the beneficiaries. Total 1,745 family caregivers wrote informed consents and 733 (response rate 42%) completed questionnaires, which included caregiver characteristics, organizational resources, primary objective and subjective stressors, perceived quality of services, and family caregiver satisfaction. Family caregivers were satisfied overall with institutional care. In multiple regression analysis, there was a statistically significant difference in degree of family caregiver satisfaction according to caregiver characteristics(relationship to beneficiary), primary objective stressors (insurance type of beneficiary), perceived quality of services(respect to family caregivers' idea, ADL support, expertness of staff, careful concern of staff, fulfillment of client's requests, and safety of institution's environment). In public long-term care, satisfaction efforts are in an early stage of development. This study is meaningful as the first attempt to measure family caregiver satisfaction with institutional care for beneficiaries under the PLTCI system, and to identify factors affecting the satisfaction. Among the identified factors, the policy makers, the insurer, and the providers need to pay attention to perceived quality of services, in particular, to improve customer satisfaction. Our findings can provide quality care improvement initiatives in the public long-term care setting.

This study was conducted to explore important factors to consider when designing voice-based psychological counseling agents amid the increasing use of conversational agents in counseling and psychotherapy. 48 participants selected their preferred agent's voice among four types (young women and men, middle-aged women and men) and had a conversation with a psychological counseling agent. They also evaluated the reasons for voice selection, mood changes, perception of the agent's characteristics, and counseling outcomes. As a results, the agent's voice type selected according to the user's gender was not statistically significant. However, the qualitative analysis showed 'comfort' of the voice was an important factor. Next, the user's mood improved significantly after the conversation with the agent, which confirmed the intervention effect. Finally, it was found that expertness and attractiveness perceptions toward the agent contributed to the counseling outcomes. The implications of the study and suggestions for future research were discussed.

Live commerce, a rapidly growing sector, facilitates real-time interaction between streamers and consumers about specific products. This business model aids rational purchasing decisions by offering visual demonstrations of product usage. This study aims to identify potential uncertainties faced by consumers in live commerce and propose strategies to mitigate these uncertainties for streamers and platforms. A research hypothesis was formulated based on prior studies and tested through surveys conducted on consumers aged 20 and above with live commerce experience. The study revealed that a streamer's credibility (trustworthiness, expertness, and reputation) significantly impacts purchase intention by mitigating uncertainty. The platform's return policy also interacted with product uncertainty, influencing consumer purchase intention. These findings provide a roadmap for creating a tailored service strategy for live commerce platforms, focusing on reducing uncertainty in the product purchase process.

Purpose: Diagnostic and functional imaging softwares in Nuclear Medicine have been developed significantly. But, there are some limitations which like take a lot of time. In this article, we introduced that the basic concept of macro to help understanding macro and its application to Brain SPECT processing. We adopted macro software to SPM processing and PACS verify processing of Brain SPECT processing. Materials and Methods: In Brain SPECT, we choose SPM processing and two PACS works which have large portion of a work. SPM is the software package to analyze neuroimaging data. And purpose of SPM is quantitative analysis between groups. Results are made by complicated process such as realignment, normalization, smoothing and mapping. We made this process to be more simple by using macro program. After sending image to PACS, we directly input coordinates of mouse using simple macro program for processes of color mapping, adjustment of gray scale, copy, cut and match. So we compared time for making result by hand with making result by macro program. Finally, we got results by applying times to number of studies in 2007. Results: In 2007, the number of SPM studies were 115 and the number of PACS studies were 834 according to Diamox study. It was taken 10 to 15 minutes for SPM work by hand according to expertness and 5 minutes and a half was uniformly needed using Macro. After applying needed time to the number of studies, we calculated an average time per a year. When using SPM work by hand according to expertness, 1150 to 1725 minutes (19 to 29 hours) were needed and 632 seconds (11 hours) were needed for using Macro. When using PACS work by hand, 2 to 3 minutes were needed and for using Macro, 45 seconds were needed. After applying theses time to the number of studies, when working by hand, 1668 to 2502 minutes (28 to 42 hours) were needed and for using Macro, 625 minutes (10 hours) were needed. Following by these results, it was shown that 1043 to 1877 (17 to 31 hours were saved. Therefore, we could save 45 to 63% for SPM, 62 to 75% for PACS work and 55 to 70% for total brain SPECT processing in 2007. Conclusions: On the basis of the number of studies, there was significant time saved when we applied Macro to brain SPECT processing and also it was shown that even though work is taken a little time, there is a possibility to save lots of time according to the number of studies. It gives time on technologist's side which makes radiological technologist more concentrate for patients and reduce probability of mistake. Appling Macro to brain SPECT processing helps for both of radiological technologists and patients and contribute to improve quality of hospital service.
