Although Due to industrial development and urbanization, the number of schools closing due to a decrease in the school-age population is increasing due to the phenomenon of relocation from farming and fishing villages. Closing schools are used as social and cultural facilities, or they are used to generate income by providing education and experiences. Agro-healing is an activity that promotes psychological, social, and physical health by using rural resources. By reflecting the Agro-healing in the services operated by the closed school, the perception of the provision of the Agro-healing service was investigated as a way to provide a therapeutic service to visitors and to increase the utilization of the closed school. The questionnaire consisted of 10 questions, a total of 5 questions related to demographic information, a total of 5 questions related to the perception of agro-healing activities in closed school facilities. As a result, 347 people participated in the survey. The higher the awareness of agro-healing, the need for a agro-healing expert, the satisfaction with the use of rural closed school facilities, and the willingness to participate in agro-healing activities, the higher the awareness that the provision of agro-healing services was necessary by the state. Theses results are expected to be useful as basic to data to solve the diverse limitation in rural closed school and agro-healing activities.

This study aims to examine the perception of false information and deepfakes according to the experience of being exposed to false information and deepfake images for YouTube content users. The study used the data from 'YouTube Use and False Information Exposure Experience' conducted by the Korea Press Foundation in 2018. For the statistical analysis, correspondent analysis was employed. The main results followed as: First, it was found that men who have been exposed to false information are most seriously aware of the problems caused by false information on YouTube. Second, regarding the need for regulation on deepfake images, women who have experienced exposure to deepfake images tended to agree, and women had a stronger awareness of the need for regulation due to damage to deepfake images than men. While YouTube users generally agree that regulation is necessary, it is required to educate YouTube users about the types of disinformation and deepfakes. In particular, it is considered to be desirable to create an environment for the self-regulation of the producers and distributors.

This study attempted to develop repetitive impact sources similar to real-life floor impact noise and to find an assessment approach corresponding to this new impact source. The necessity for the development of the new impact source arises from the fact that issues related to floor impact noise in actual residential buildings mainly stem from children running. However, the standard impact sources which have been used for measuring and evaluating floor impact noise are of single-impulse type, which differs from the actual problematic impact sources. The study encompassed 18 evaluation items, and the results suggest that items applicable for assessing floor impact noise include psychological effects (annoying, becoming angry), disturbances to daily life (interference with sleep, disruption of relaxation), and physiological effects (elevated blood pressure). These items can be employed individually and, depending on the type of evaluation for floor impact noise, can be selectively utilized. By doing so, more comprehensive evaluations of auditory experiments in laboratories or assessments of residential noise in living environments related to floor impact noise could be conducted.

The aim of this study is to evaluate Korea's employment policy for people with disabilities by utilizing situational feasibility evaluation of Fisher's multi-dimensional policy evaluation methods (1995, 2003). A number of related studies conducted so far have been focused only on quantitative research methods. In other words, balanced and comprehensive evaluation studies were insufficient. Therefore, this study attempted a balanced policy evaluation through a qualitative or phenomenological approach that complements the limitations of the existing empirical methodology. In this study, the sub-topics for evaluation were divided into employment delivery system, employment program, and institutional employment environment for people with disabilities. Improvement measures and policy implications for each topic were presented. In order to improve employment services and jobs for people with disabiliyies, it was suggested that there is a need to strengthen linkages and cooperation between institutions, eliminate blind spots in employment services, improve quality, expand customized employment services, strengthen programs, improve policy and institutional environments, and strengthen individual psychological and emotional support.

This study aimed to provide knowledge helpful for understanding voice problems related to occupations in the clinical field through an investigation and comparison of subjective vocal symptoms of 12 professional actors and 12 speech-language pathologists Among the 11 symptoms, "Difficulty with high pitch when singing," "Hypertension in the neck when speaking," and "Feel voice fatigue" were the most frequent symptoms in both groups. Additionally, the professional voice users reported a higher frequency of "Difficulty with high pitch when singing" (p=.049), "Hoarse voice" (p=.021), "Difficulty (requiring effort) when speaking" (p=.032), "Pain in the neck when speaking" (p=.009), and "Feel vocal fatigue" (p=.018) than the elite vocal performer group. This may be due to the different voice-related environments and differences in voice demands during occupational activities between the two groups.

This study analyzes the economic feasibility on the transition of production structure to increase income for a local forest village in Laos PDR. The study area was the Nongboua village in Sangthong district where the primary product is rice from rice paddy. Possible strategies were considered to increase the villagers' revenue, and Noni (Morinda citrifolia) was production in the short-term. We assumed that the project period was for 20 years for the analysis, and a total of 1,100 Noni tree was planted in 1 ha by $3m{\times}3m$ spacing. This study classified basic scenario one, scenario two, scenario three by the survival rate and purchase pirce of Noni. Generally Noni grows well. However, the seedlings' average survival rate (= production volume) was set up conservatively in this study to consider potential risks such as no production experience of Noni and tree disease. The scenario one assumed that the survival rate of Noni seedlings was 50% for 0-1 years, 60% for 0-2 years, and 70% for 3-20 years; the scenario two, 10% less, i.e., 40%, 50%, and 60%; and the scenario three, 10% less, i.e., 40%, 50%, 60% and purchase price 10% less, i.e., $0.29 to $0.26, respectively. Our analysis showed that all 3 scenarios resulted in economically-feasible IRR (internal rate of return) of 24.81%, 19.02%, and 16.30% of with a discounting rate of 10%. The B/C (benefit/cost) ratio for a unit area (1ha) was also analyzed for the three scenarios with a discounting rate of 10%, resutling in the B/C ratio of 1.71, 1.47, and 1.31. The study results showed that the Nongboua village would have a good opportunity to improve its low-income structure through planting and managing alternative crops such as Noni. Also the results can be used as useful decision-making information at a preliminary analysis level for planning other government and public investment projects for the Nonboua village.

Korean farm villages are locked in vicious circle, as lots of their problems related to low income and hollow matters are geared and multiply. To get over those problems, various plans to develop Korean farm villages are being pushed ahead. In addition, since the early of 1990s, Korea has been projects to develop settlement zones and culture villages. It has been also preceeding with a comprehensive development project of farm villages and a new vitalizations project, etc. All of these projects aim to reorganize and expand life environments, industrial bases, and convenience and welfare facilities. The existing studies on a comprehensive project to develop farm villages have been focusing on evaluation indexes, problems, investment priorities, etc. But in fact, studies on a comprehensive development project of farm villages are not thoroughgoing enough in aspects of residents' attitude and their recognition on the influence on tourist development. Thus, this study aims to present strategic schemes to allow residents to actively participate in a stage of promoting a comprehensive development project of farm villages, a stage of making the plan, and a stage of the implementation. For this, this study analyzes a comprehensive development project of farm villages and attempts to figure out which influence the tourist development in farm villages has on residents' attitude and recognition resulting from changes in economic, social cultural, and environmental aspects. Especially, this study previously examines what influential factors there exists are and what influences the development of farm villages has on residents. Based on the results from the above analysis, schemes to enable residents to actively a comprehensive development project of farm villages are presented as follows. First, it is necessary to raise our recognition on tourism and tourism development of farm villages. If the main theme of a comprehensive development project of farm villages intends farm village development, it is required to educate residents and let them clearly raise their recognition on tourism, and the effect of the project is guaranteed. Second, it is highly required to make a plan so that we can feel economic effects of revenues through project promotion and positive effects including the expansion of infrastructures and welfare facilities, etc. Third, it is necessary to bring into relief the positive recognition and attitude of a comprehensive development project of farm villages. As for the negative recognition and attitude, it is very important to change negative residents' recognition to the positive direction and to allow them to participate in and to take an interest in the project, so that the project can be effectively promoted.

It is necessary to build a quality-enhancing forest leisure sports facility according to values that value life quality, national forest policy. Vita Parcours (fitness trails) is found to be the activities highly convenient, so their introduction and promotion in Korea should be highly considered. field survey was necessary to explore the possibility of installing Vita Parcours. Several sites were selected, such as Asean recreational forest, Unaksan recreational forest, Yumyeongsan recreational forest, Saneum recreational forest, Jungmisan recreational forest and National center for forest therapy. At these locations, we explored the current status of forest facilities and forest trails. A total number of 31 exercise facilities has been identified and surveyed, some of which are located on the trails (2), alongside the trail (9), alongside trail boundaries (2) or represent facilities suitable for both outdoor and indoor exercise within the forest (18), all of whom provide location for 44 different exercise routines (flexibility exercises (23), endurance (12) and strength exercises (9)). Field work also included identification of forests paths, the total number of whom was 34 paths - 30 identified as trails, 2 as hiking trails, 1 as a forest path for relaxation and healing and 1 as an exploratory path. Regarding the structure and shape of these trails, 32 was straight in shape and only 2 designed as a circular forest trails. Average length of these trails was 652.2m with the highest and the lowest point altitude difference of 60m, on average. Saneum recreational forest provide the most suitable site/environment for Vita Parcours and as a result of this, Saneum recreational forest is proposed as a location to support the endeavors in promotion of these valuable forest fitness trails. Among the forest paths at this site, a forest path which has a length of 1.84km and 73.0m the highest and the lowest point altitude difference was selected as the most suitable, and may be equipped with necessary stations for exercise or obstacles. In addition, if these trails are to be introduced and welcomed by its users, we must assure that they are properly maintained.
