Purpose: This study aimed to identify whether there is a difference between an online-based community psychiatric nursing practice program with the ARCS model and a conventional community psychiatric nursing practice program in promoting nursing students' learning motivation, knowledge of community psychiatric nursing, communication skills, and learning self-efficacy. Methods: This study used a quasi-experimental design with a non-equivalent control group. The participants were 44 nursing students at three nursing colleges in Gyeongsangbuk-do. The experimental group was provided the online-based community psychiatric nursing practice program with ARCS model, while the control group was provided the conventional community psychiatric nursing practice program from July 9, to September 3, 2022. Both groups received practice training 8 hours a day, 5 days two weeks. The collected data were analyzed using the exact χ², Mann-Whitney U-test, and Quade's two-way ANCOVA with the IBM SPSS Statistics 28.0 program. Results: The results of the comparison of an experimental group training with the online-based community psychiatric nursing practice program with ARCS model and a control group training with the conventional community psychiatric nursing practice program showed that, there was no statistically significant difference between the two groups in learning motivation knowledge of community psychiatric nursing, and learning self-efficacy. However, communication skills were statistically significantly higher in the experimental group (F=6.23, p=.017). Conclusion: The online-based community psychiatric nursing practice program with ARCS model can be used as a substitute learning to improve community psychiatric nursing capabilities in situations when clinical practice is suspended due to infectious diseases such as coronavirus disease 2019 or when is a shortage of community psychiatric nursing practice institutions.

The purpose of this study is to find out apartment residents' consciousness and needs of their community facility by age group as to provide basic data for future community facility planning. For this study, 12 national rental apartment complexes in the Seoul Metropolitan area were selected, and the residents of diverse age groups were surveyed including children, adolescents, adults, and elders regarding their attitude, satisfaction, and necessity of using the community space, and their requests for programs and locations of the community space. As for the analysis method, statistical software, SPSS for Windows 14.0, was used, and total of 891 questionnaires were analyzed for the survey. The findings of this study are as follows. 1) As to major activities in national rental apartment community facilities, older residents tended to show more interest in health, while younger residents tended to show more interest in leisure. 2) The residents' satisfaction about community facilities was the highest among children, and was the lowest among adults in general. Particularly, the facilities that were designed for specific age groups of users showed high satisfaction among users. Therefore, community facilities need to be planned in consideration of each age group of users. 3) Residents' requests for community facilities, in general, were found more among adults and elders than among children and adolescents. Elders made requests for the green environment, and adults made requests for facilities for family uses. 4) As to the results of surveying the requests about community facility programs, children, adolescents, and adults all made requests for programs regarding leisure activities. However, elders made requests for programs related to health or communication with neighbors. Therefore, the purposes and requests of using community facilities need to be identified precisely and then plan them accordingly and effectively.

This study examines the effect of sense of community on the relationship between learner satisfaction and influencing factors related to the online learning environment. Influencing factors related to the online learning environment are derived from previous literature and classified into two groups : social dimension (leader's enthusiasm, offline activities) and system dimension (usefulness, ease of use, enjoyability). Learner satisfaction is defined as the learners' perceived learning gains from taking an online class. Study participants included 250 university students from two different institutions. The participants were divided into 43 groups and asked to complete an online TOEIC preparation module using a commercial cooperative learning system over 4 weeks. Data were collected at three points for each participant, at the beginning, 3 weeks after, and at the end of the online module. Two system factors related to the online learning environment (ease of use, usefulness) directly influenced learner satisfaction, while social factors indirectly influenced learner satisfaction through the mediating role of sense of community.

In this exploratory analysis, we investigate the genesis and the evolution of local food-purchasing networks created and operated by consumers. In details, we describe how collecting and sharing information about food-products can become a central activity for some consumers' communities and how these communities are starting to play an active role in the food supply chain. We define this community-based food-purchasing model as collaborative food network (CFN), and we analytically describe its characteristics and differences with respect to the traditional and industrialized agrifood supply chain models. A collaborative food network community in Italy, known as GAS ("Gruppi di Acquisto Solidale" - "Solidarity Purchasing Groups"), is introduced as an example of our analytical model. We will use this empirical example to present the strengths and weaknesses of the CFN model.

We investigated the spring and summer community structure of meiobenthos in a tidal-falt near Iwon, Korea, in 2002 and 2003. In total, 12 meiofaunal groups were found in the study area among which nematodes were the most dominant. Benthic foraminiferans, harpacticoid copepods, polychaetes, and crustacean nauplli were also dominant groups at all sites. The total density of meiobenthos at each station was be 246-2,177 ind./$10cm^2$. As the depth of sediment increased, the density of meiobenthos at each station gradually decreased. Changes in the vertical distribution of meiobenthos in the study area occurred mainly near the sediment surface (0-1 cm). Generally, between spring and summer the density of nematodes increased, and the density of other dominant meiofaunal groups (benthic harpacticoids, crustacean nauplii, benthic foraminiferans) decreased near the sediment trap the control site of sediment traps compared to that at the control site. The results of cluster and multidimensional scaling plots indicate that the meiofaunal community changed following construction of a low artificial wood groin structure.

Purpose: The purpose of this study is to identify risk factors of accidental falls by age in the Korean elderly. Methods: The study subjects included 10,242 community-dwelling elders aged 65 or over. The data were analyzed by logistic regression analysis. Results: The risk factors of accidental falls in the younger old group (aged 65~74) include fear of falling (OR=16.28, 95% CI: 12.03~22.03), depression (OR=1.24, 95% CI: 1.06~1.44), and hearing impairment (OR=1.20, 95% CI: 1.01~1.43). The risk factors of accidental falls in the older old group (aged 75~84) include fear of falling (OR=11.54, 95% CI: 7.04~18.93), muscle strength (OR=1.36, 95% CI: 1.15~1.60), number of chronic disease (OR=1.65, 95% CI: 1.09~2.50), and presence of spouse (OR=1.27, 95% CI: 1.06~1.51). The risk factors of accidental falls in the oldest old group (aged 85 years old or older) include fear of falling (OR=8.05, 95% CI: 1.85~34.98) and exercise (OR=2.91, 95% CI: 1.36~6.24). Fear of falling is defined as a common factor in the all age groups. Conclusion: Different strategies should be developed for age groups to prevent elderly falls with understanding of contributing factors of falls in each group.

This study investigated the use of community information and communication technologies in light of its dual visions (i.e., serving as an affordable Internet service provider and a community building tool). Surveying the randomly selected users of a community network (n = 213), this study examined the influence of the community features on service use compared to that of Internet features. The present study found that the respondents were using the service mainly for general Internet features, such as email and web access. More than two-thirds of the respondents did not recognize community contents as available service. Community features of the service were found as significant predictors of use only among people who were aware of community contents but not among people who were not. Nonetheless, there was no difference in the amount of use between the two groups, indicating that the awareness of community contents itself did not increase use. Findings suggest that the service providers did not fully communicate the community aspect of the service with the users although the very aspect distinguishes the service from other Internet services.

내연산의 삼림식생을 대상으로 ZM식물사회학적 방법에 의해 군락단위 및 그 하위단위를 분류하고, 분류된 각 단위와 환경사이의 상관관계를 서열법으로 해석하여 내연산 산림식생관리를 위한 기초자료를 제공할 목적으로 본 연구를 수행하였다. 군락단위는 신갈나무군락, 굴참나무군락, 소나무군락, 서어나무군락, 느티나무군락이 구분되었고, 하위단위는 신갈나무군락에서 철쪽꽃군과 참회나무군, 굴참나무군락에서 우산나물군, 털조록싸리군 및 찰피나무군, 느티나무군락에서 까치박달군과 고욤나무군이 각각 세분되었다. 따라서 내연산 일대의 산림은 5개군락, 7개군으로 총 9개의 식생단위로 분류되었다. CCA 방법으로 식생과 환경사이의 상관관계 분석 결과 내연산 지역의 식생단위는 해발과 가장 높은 상관관계가 있는 것으로 나타났다. 신갈나무군락의 철쪽꽃군과 참회나무군은 해발고와 지형이 높은 곳과 노암율이 낮은 곳에 각각 분포하는 경향이었다. 한편 느티나무군락은 신갈나무군락과 역의 관계로 나타났다. 앞으로 산림식생관리시 특히 계곡림에 대해서는 교목층의 우점종들이 상관적으로 이질적인 모습을 하고 있더라도 하나의 관리단위로 고려되어야 할 것으로 판단되었다.
