Virtual manufacturing technology has been applied in actual production sites with the development of virtual reality technology. However, the current virtual manufacturing technology requires experts for application of the system. Furthermore, the sense of reality is diminished as the entire simulation is driven by virtual objects. In contrast, mixed reality can visualize virtual objects and an actual work place simultaneously, and thus the sense of reality of the virtual manufacturing simulation can be improved. This paper introduces a method that applies mixed reality in the manufacturing process, and proposes a method to adapt general safety sign post in the factory instead of a black square marker for visual fiducial recognition.

Most human emotions are conveyed through facial expressions, which represent the predominant source of emotional data. This research investigates the impact of crowds on human emotions by analysing facial expressions. It examines how crowd behaviour, face recognition technology, and deep learning algorithms contribute to understanding the emotional change according to different level of crowd. The study identifies common emotions expressed during congestion, differences between crowded and less crowded areas, changes in facial expressions over time. The findings can inform urban planning and crowd event management by providing insights for developing coping mechanisms for affected individuals. However, limitations and challenges in using reliable facial expression analysis are also discussed, including age and context-related differences.

The purpose of this study was to investigate the effects of safety culture on the safety consciousness and safety behaviors of manufacturing workers, and to suggest ways for manufacturing workers to understand the safety culture and improve safety consciousness and safety behavior. To achieve this research objective, out of 176 industrial complexes in Seoul and Gyeonggi Province registered with the Korea Industrial Complex Corporation, workers at 50 industrial complexes, including the Korea Export-Industrial Complex and Seoul's Onsuji, were subject to research. The implementation of this survey distributed 300 questionnaires through the mid-level managers of manufacturers and environment safety and health managers over a period of one month from August 1st to 31st, 2019, finally statisticalizing the data in 282 parts excluding 18 questionnaires deemed to have been unresponsive. First, the safety culture (safety climate, safety procedures) has a positive effect on the safety consciousness (recognition of importance, interest and participation inducement) of the manufacturing workers. Second, the safety culture (safety climate, safety procedures) has a positive effect on the safety behavior (safety planning, safety check) of manufacturing workers. Third, safety consciousness (recognition of importance, interest and inducement of participation) has a positive influence on the safety behavior (safety planning, safety check) of manufacturing workers. Fourth, the safety consciousness (recognition of importance, interest and inducement of participation) appears to have a partial mediating effect in relation to safety culture (safety climate, safety procedure) and safety behavior (safety planning, safety check) of manufacturing workers. The implication of this study is that although the industrial accidents have occurred in the manufacturing industry in recent years, the studies on the workers in the manufacturing industry are insufficient. However, this study is meaningful that it has suggested ways for manufacturing workers to understand the safety culture and improve the safety consciousness and safety behavior by analyzing the effects of safety culture on safety consciousness and safety behavior of manufacturing workers.

A human-friendly interactive system, based on the harmonious symbiotic coexistence of human and robots, is explored. Based on interactive technology paradigm, a robotic cane is proposed for blind or visually impaired travelers to navigate safely and quickly among obstacles and other hazards faced by blind pedestrians. Robotic aids, such as robotic canes, require cooperation between humans and robots. Various methods for implementing the appropriate cooperative recognition, planning, and acting, have been investigated. The issues discussed include the interaction of human and robot, design issues of an interactive robotic cane, and behavior arbitration methodologies for navigation planning.

This paper is to provide an integration approach between design and process planning for mechanical parts, using feature recognition. We develop a method to extract each individual feature of an object from 3D modeling data using face-edge graph based algorithm and then propose an approach to recognize the volumic form features using heuristic rules. we demonstrate the proposed approaches are effective for such basic shapes as pocket, slot, through hole, etc.

This study aims to make a comparison of the attitudes between residents, officials and experts towards the rural landscape management polices. It is also designed to suggest the improvements to the rural landscape management policies. This study showed that there were differences in awareness of the rural landscape management polices depending on stakeholder who are residents, officials and experts and experienced groups of rural landscape projects. The directions of improvement of rural landscape policies are as follows: First, it's necessary that the various rural landscape management polices is made of considering the differences on the interest group's recognition. Second, the related rural landscape improvement programs should be implemented based on those plan. Third, the various programs which are to lead voluntary residents participation and to strengthen participant's capabilities have to be arranged to manage the rural landscape effectively.

Objectives : This research was performed to investigate the characteristics and determination factors of health care policy satisfaction and welfare recognition for health insurance & health care financing. Methods : The utilized data were 4,174 cases who responded to a welfare recognition survey in the 8th wave of the Korea Welfare Panel Study (2013). The statistical methodology used in this study is the multiple regression model. Results : The significant affecting factors of health care policy satisfaction were age, education, household income, welfare attitudes, and health status. Medical utilization & private medical insurance were not related to health care policy satisfaction. The affecting factors of health insurance reinforcement were age, health status, welfare attitudes. The affecting factors of health care financing expansion were age, economic activity type, medical utilization, welfare attitudes. The affecting factors of welfare attitudes were age, economic activity type, household income, health insurance, and health status. Conclusions : Health care policy satisfaction, health insurance reinforcement, and health care financing expansion were all affected by age and welfare attitude; but this was not the case for private health insurance. This study recommended that the Korean government provide active planning for reinforcement of health insurance and publicity of the health care system in order to accord with the prospects of people.

This study is purposed to compare PR activities among the 5 large hospitals in Seoul and Kyonggido. The research methods are used in interview survey for employees and Questionnaires survey for patients or their relatives. The 427 patients or their relatives(response rate: 85.4%) were surveyed. The hospital which is below, is more active than any others in special PR activities. 1. Distribution of hospital information books: E, P, A 2. Distribution of calendar: P 3. Broadcast in hospital: E 4. Education of employees about PR : E, A 5. Education of employees about service: all hospitals are active. The PR sectors are organized under the Department of planning(S,J,E) or CEO(P,A). And the budget of PR activities is almost a similar level among all. The degree of recognition and utilization for PR activities is not different among hopitals by the sociodemographic variables of patients. And the average of correlation ratio between recognition of each hopital's PR activities and its utilization is 62.01%(range:51.29%-67.98%) average.
