This paper investigates the effects of entrepreneurs' cognitive biases on business opportunity evaluation, given their strong entrepreneurial spirit, which is characterized by innovation, proactivity, and risk-taking. When making decisions related to business activities, entrepreneurs typically make rational judgments based on their knowledge, experience, and the advice of external experts. However, in situations of extreme stress or when quick decisions are required, they often rely on heuristics based on their cognitive biases. In particular, we often see cases where entrepreneurs fail because they make decisions based on heuristics in the process of evaluating and selecting new business opportunities that are planned to guarantee the growth and sustainability of their companies. This study was conducted in response to the need for research to clarify the effects of entrepreneurs' cognitive biases on new business opportunity evaluation, given that the cognitive biases of entrepreneurs, which are formed by repeated successful experiences, can sometimes lead to business failure. Although there have been many studies on the effects of cognitive biases on entrepreneurship and opportunity evaluation among university students and general people who aspire to start a business, there have been few studies that have clarified the relationship between cognitive biases and social networks among entrepreneurs. In contrast to previous studies, this study conducted empirical surveys of entrepreneurs only, and also conducted research on the relationship with social networks. For the study, a survey was conducted using a parallel survey method using online mobile surveys and self-report questionnaires from 150 entrepreneurs of small and medium-sized enterprises. The results of the study showed that 'overconfidence' and 'illusion of control', among the independent variables of entrepreneurs' cognitive biases, had a statistically significant positive(+) effect on business opportunity evaluation. In addition, it was confirmed that the moderating variable, social network, moderates the effect of overconfidence on business opportunity evaluation. This study showed that entrepreneurs' cognitive biases play a role in the process of evaluating and selecting new business opportunities, and that social networks play a role in moderating the structural relationship between entrepreneurs' cognitive biases and business opportunity evaluation. This study is expected to be of great help not only to entrepreneurs, but also to entrepreneur education and policy making, by showing how entrepreneurs can use cognitive biases in a positive way and the influence of social networks.

The purpose of this study is to construct user satisfaction model using factor analysis and regression analysis through survey on various factors which decide users' satisfaction index of OK-SUNG Recreation Forest located in Gumi-city, Kyungbuk (newly opened on Dec, 26, 2007) and to suggest the right operation plans referring to the studies on existing recreation forests. The research results are as follows; The using behavior of recreation forests reported similar pattern to existing researches such as companion pattern, duration of status, ages and costs. The result of construction regression model after dividing of using behavior of recreation forests into two sections, which are physical sector and mental sector, showed that recreation environmental factor and inner recreation factor influenced more highly on satisfaction index. This result showed that the recreation factor, which is for obtaining mental satisfaction and friendship among companions, nature friendly factor and environmental factor more highly influence on the satisfaction index and the existing studies also support this result. Therefore, in order to offer higher standard recreation opportunities to the users, there needs consideration not only concerning experience facilities, walks and paths up a mountain, but also concerning the harmony between nature and facilities. In addition, in order to offer comfort and stableness in body and mind to users, it is necessary to educate and train the staff to offer better service and to maintain the facilities of recreation forest peaceful and calm.

The results of researching on duties of physical therapist, understanding of elderly diseases and policies related with elderly welfare came out from the survey before beginning of education to physical therapists who attended National Elderly Welfare Physical Therapist Workshop during Sep. 11th to 14th, 2007. They have already understood about long-term elderly care insurance from the policy, and responded that those policies will bring more advantage to elders. On contrary, negative response had reason of low service quality. About elderly care system, there were positive answer of appropriate alternatives to support them, but also other critics had opinion of inevitable choice for living conservation. About understanding of elderly diseases, there were more comprehension of diseases as age gets higher, but most did not understand dementia and paralysis. Past experience and process of medical treatment for their disease were such arthritis, paralysis, broken bone, and dislocation of joint. Prognosis of technical training was mostly answered positively, but linking with other related disease programs were not welcomed. Most respondents thought that professional training were needed. The results of understanding diseases during senescent had high percentage of understanding as age and education was high, and it had eye upon statistics of the survey (p < 0.05) Most of those questioned responded that it is appropriate to have six working days per week and eight hours of daily work, however, present wage is not reasonable. Most of those questioned had negative response of work independence, and had an-swered that there should be certificates needed in related fields. For difficulties during work period, they had hardship instituting direction of treatment by lack of program, level of wage, and physical difficulties. Physical therapists averagely wished to have fewer than thirty patients per therapist. After the research, physical therapists who work in those facilities of elderly care systems agreed on policies, though it should not lower service quality. In addition, they were pros to have elderly care system, yet they are still inevitable option to maintain living. For work environment, the period of work was appropriate, but had different opinions for work independence and regular number of patients. Therefore, there should be more organized treatment program that also should be linked to other practical programs at this beginning point of the policy enforcement and the time that many therapists hope to work in elderly care system.

The concepts of activity involvement(AI) and place attachment(PA) are useful for explaining the sustainable use of natural resources by humans. Although several studies have investigated the effects of AI and PA on environmental behaviors and found its implications, it has not examined the simultaneous effects of both AI and PA. Thus, the purpose of this study was to develop a typology of both AI and PA. This typology was used to explain the environmentally responsible behaviors of visitors. The study sample surveyed 587 users of the main trail in Namhansanseong Provincial Park The results were analyzed by frequency, reliability, factor analysis, cross-tabulation, T-test, correlation and ANOVA analysis. As a result, the typology identified four subgroups of hikers based on involvement in hiking and attachment to setting. Results also indicate that environmentally responsible behaviors do vary significantly across typology. In detail, general environmental behavior and specific environmental behavior were significantly different between the four groups. These finding suggests that PA seems to play a more powerful role than AI in relation to environmental behavior. While more involved and more attached hikers were more active in environmental behaviors, less involved and less attached hikers had a more passive attitude. In this respect, this study placed emphasis on the fact that the future resource management of tourism and outdoor recreation may be established based on its activity experience in certain place.

This study is to examine the section-based stream management with environmental characteristics and user monitoring. In Jeonjucheon, upstream section located near to Jeonju Hanok village has very good water quality and natural stream landscape. In case of mid/down streams, water quality is good and heavy concentration of facility leads to high use rates of these sections. The questionnaire consists of 5 parts: user characteristics, use behavior, citizen participation, importance rank, and Importance-Satisfaction(IS). 383 out of 454 responses with listwise deletion are used for demographic analysis and IS Analysis. In terms of citizen participation through 'ecological experience activity' and 'stream stewardship activity', 'occasional participation' shows the average of 78% in all three sections. For importance rank, the results arranged in order of priority show 'water quality' > 'green corridor' > 'trail' in up/down streams and 'water quality' > 'vegetation management' > 'trail' in midstream. Therefore, 'water quality' appears to be the most important variable among 13 variables. At last, the results of ISA indicate that all 10 variables need to be improved as satisfaction is lower than importance. In addition, 'plant management' variable falls into 'concentrate here' quadrant where importance is high and satisfaction is low.

Purpose: This study is to examine the intention of the elderly who live alone in the customized AI speaker for the elderly living alone to improve the quality of life service for the elderly living alone in the smart city environment. Based on the quality of life model of the elderly, this study is applied to the technology acceptance model to investigate the relationship between perceived usefulness and ease of use on the sustained use intention. Research design, data and methodology: Residents in Suwon, Gyeonggi-do, selected as candidate local governments for the Smart City Challenge Project of the Ministry of Land, Infrastructure and Transport in June 2019 to measure the perceived technology acceptance of potential users for the AI technology for the elderly living alone as part of the smart city technology. In order to evaluate the intention of using AI speaker, which is the target system of this study, a video of a chatbot using experience of elderly people living alone was produced. Results: First of all, in order for the elderly living alone to have an attitude to use AI-based speakers, there should be a perceived usefulness of the quality of life of the elderly. However, ease of use did not show any significant causal relationship to attitude toward use. In addition, the attitude toward use weakly influenced the intention to use. In other words, elderly people living alone were not likely to have a significant effect on their attitude toward use. However, feeling that AI speakers are easy to use will help to improve the quality of life, which in turn led to the attitude toward using AI speakers, which could lead to indirect effects. Finally, the perceived usefulness of quality of life was found to have a weak effect on direct use intentions. Conclusions: This study conducted a study on the technology acceptance of service environment to improve the quality of life for the specific user group who live alone in the smart seat environment. In this study, we examined the effects of AI speaker on the elderly living alone to improve the quality of life for the elderly living alone.
