In order to explore the stable anchoring conditions of coal side under the mining disturbance of soft section coal pillar in Wangcun Coal Mine of Chenghe Mining Area, the distribution model of the anchoring support pressure at the coal pillar side was established, using the strain-softening characteristics of the coal to study the distribution law of anchoring coal side support pressure. The analytical solution for the reinforcement anchorage stress in the coal pillar side was derived with the inelastic state mechanical model. The results show that the deformation angle of the roadway side and roof increases with the roof subsidence due to the mining influence at the adjacent working face, the plastic deformation zone extends to the depth of the coal side, and the increase of anchorage stress can effectively control the roof subsidence and further deterioration of plastic zone. The roadway height and the peak support pressure have a certain influence on the anchorage stress, the required anchorage stress of the coal side rises with the roadway height and the peak support pressure. The required anchorage stress of the coal pillar side decreases as the cohesion between the coal seam and the roof and floor and the anchor length increases. Then, applied the research result to Wangcun coal mine in Chenghe mining area, the design of anchor cable reinforcement support was proposed for the section of coal pillars side that has been anchored and deformed, which achieved great results and effectively controlled the convergence and deformation of the side, providing a safety guarantee for the roadway excavation and mining.

The main purpose of this study was to identify the effects of group social support and individual social support on the reduction of burden and improvement in family functioning of families with asthmatic children. The design of this study was a randomized pre-posttest quasi-experimental design to compare the two experimental groups. The theoretical framework for this study was derived from the study of burden in family caregivers by Suh and Oh (1993) based on the main effect model of social support theories. The data were collected from February 12, 1998 to May 29, 1998 at the pediatric out patient department of a university hospital located in Suwon city. The sample consisted of 39 family members who were identified as families with asthmatic children, Eighteen subjects were randomly assigned to the group social support group and 21 were assigned to the individual social support group. Group and individual social support members were seen for 60 to 90 minutes, four times over one to three weeks. The instruments used in this study were the Burden Scale developed by Suh & Oh(1993), the Visual Analogue Scale, and the Family Adaptability Cohesion Evaluation Scale(FACES-III) developed by Olson, Portner, and Lavee(1985). The collected data were analyzed using Mann-Whitney test, x$^2$-test, Wilcoxon sign rank test, t-test, ANOVA (Scheff), Pearson correlation coefficient. multiple regression, and social support process and content analysis. The results are as follow : 1. There was no significant difference before the experimental treatment among the subjects in the group social support group and individual social support group for general characteristics, burden, or family functioning. 2. Hypothesis 1 : “There will be a greater reduction on the burden score of the group social support group compared to the individual social support group” was not statistically significant(U＝174.5, p＝.683). The burden scores showed a significant decrease after participation in social support as compared to before participation for both groups. However there was a tendency for more reduction in the burden scores for the group social support than for individual social support. 3. Hypothesis 2 : “There will be a greater improvement in the family functioning scores for the group social support group compared to the individual social support group” was not statistically significant(U＝153.0. p＝.309). There was a tendency toward improvement in the family functioning scores of the group social support as compared to that of the individual social support. 4. According to the length of the treatment period, families with asthmatic children displayed affirmative responses, and the families set up a self-help group of mothers with asthmatic children in order to share their experiences, to get information and to solve their problems. In conclusion, it was found that group social support was the more effective nursing intervention for reducing burden and for improving family functioning of families with asthmatic children.

Background: Oral health is an important element of well aging. And oral health also affects overall health, mental health, and quality of life. In this study, we sought to identify oral health influencing factors and research trends for well-aging through text analysis of research on well-aging and oral health over the past 12 years. Methods: The research data was analyzed based on English literature published in PubMed from 2012 to 2023. Aging well and oral health were used as search terms, and 115 final papers were selected. Network text analysis included keyword frequency analysis, centrality analysis, and cohesion structure analysis using the Net-Miner 4.0 program. Results: Excluding general characteristics, the most frequent keywords in 115 articles, 520 keywords (Mesh terms) were psychology, dental prosthesis and Alzheimer's disease, Dental caries, cognition, cognitive dysfunction, and bacteria. Research keywords with high degree centrality were Dental caries (0.864), Quality of life (0.833), Tooth loss (0.818), Health status (0.727), and Life expectancy (0.712). As a result of community analysis, it consisted of 4 groups. Group 1 consisted of chewing and nutrition, Group 2 consisted oral diseases, systemic diseases and management, Group 3 consisted oral health and mental health, Group 4 consisted oral frailty symptoms and quality of life. Conclusion: In an aging society, oral dysfunction affects mental health and quality of life. Preventing oral diseases for well-aging can have a positive impact on mental health and quality of life. Therefore, efforts are needed to prevent oral frailty in a super-aging society by developing and educating systematic oral care programs for each life cycle.

A challenge in fostering virtual communities is the continuous supply of knowledge, namely members' willingness to contribute knowledge to their communities. Previous research argues that giving away knowledge eventually causes the possessors of that knowledge to lose their unique value to others, benefiting all except the contributor. Furthermore, communication within virtual communities involves a large number of participants with different social backgrounds and perspectives. The establishment of mutual understanding to comprehend conversations and foster knowledge contribution in virtual communities is inevitably more difficult than face-to-face communication in a small group. In spite of these arguments, evidence suggests that individuals in virtual communities do engage in social behaviors such as knowledge contribution. It is important to understand why individuals provide their valuable knowledge to other community members without a guarantee of returns. In virtual communities, knowledge is inherently rooted in individual members' experiences and expertise. This personal nature of knowledge requires social interactions between virtual community members for knowledge transfer. This study employs the social capital theory in order to account for interpersonal relationship factors and identity theory for individual and group factors that may affect knowledge contribution. First, social capital is the relationship capital which is embedded within the relationships among the participants in a network and available for use when it is needed. Social capital is a productive resource, facilitating individuals' actions for attainment. Nahapiet and Ghoshal (1997) identify three dimensions of social capital and explain theoretically how these dimensions affect the exchange of knowledge. Thus, social capital would be relevant to knowledge contribution in virtual communities. Second, existing research has addressed the importance of identity in facilitating knowledge contribution in a virtual context. Identity in virtual communities has been described as playing a vital role in the establishment of personal reputations and in the recognition of others. For instance, reputation systems that rate participants in terms of the quality of their contributions provide a readily available inventory of experts to knowledge seekers. Despite the growing interest in identities, however, there is little empirical research about how identities in the communities influence knowledge contribution. Therefore, the goal of this study is to better understand knowledge contribution by examining the roles of social capital and identity in virtual communities. Based on a theoretical framework of social capital and identity theory, we develop and test a theoretical model and evaluate our hypotheses. Specifically, we propose three variables such as cohesiveness, reciprocity, and commitment, referring to the social capital theory, as antecedents of knowledge contribution in virtual communities. We further posit that members with a strong identity (self-presentation and group identification) contribute more knowledge to virtual communities. We conducted a field study in order to validate our research model. We collected data from 192 members of virtual communities and used the PLS method to analyse the data. The tests of the measurement model confirm that our data set has appropriate discriminant and convergent validity. The results of testing the structural model show that cohesion, reciprocity, and self-presentation significantly influence knowledge contribution, while commitment and group identification do not significantly influence knowledge contribution. Our findings on cohesion and reciprocity are consistent with the previous literature. Contrary to our expectations, commitment did not significantly affect knowledge contribution in virtual communities. This result may be due to the fact that knowledge contribution was voluntary in the virtual communities in our sample. Another plausible explanation for this result may be the self-selection bias for the survey respondents, who are more likely to contribute their knowledge to virtual communities. The relationship between self-presentation and knowledge contribution was found to be significant in virtual communities, supporting the results of prior literature. Group identification did not significantly affect knowledge contribution in this study, inconsistent with the wealth of research that identifies group identification as an important factor for knowledge sharing. This conflicting result calls for future research that examines the role of group identification in knowledge contribution in virtual communities. This study makes a contribution to theory development in the area of knowledge management in general and virtual communities in particular. For practice, the results of this study identify the circumstances under which individual factors would be effective for motivating knowledge contribution to virtual communities.

The purpose of this study was examining the effects of family sandplay therapy with structural family therapy in improving the family strengths of children with emotional and behavioral disorders. First, we looked for a way to combine family sandplay therapy with structural family therapy and formulated an approach that could maximize the strengths of each theory and complement each other's weaknesses. And then we applied family sandplay therapy together with structural family therapy and analyzed its effects on family strengths. The subjects of this study were 10 families of children with emotional and behavioral disorders, and they were divided into an experimental group with 5 families and a control group with the other 5. To the experimental group received 16 sessions of family sandplay therapy with structural family therapy. In order to prove the effectiveness of family sandplay therapy with structural family therapy on family strengths, a family relationship( husband-wife relationship, parent-child relationship, and sibling relationship) scale and a family function(family cohesion, family adaptability) scale were used. The main findings of this study are as follows. First, the family relationships of the families with emotional-behavioral disorder children were improved after the application of family sandplay therapy with structural family therapy. Second, the application of family sandplay therapy with structural family therapy improved the family function of families with emotional-behavioral disorder children. Third, in the course of family sandplay therapy with structural family therapy, family sand tray was changed in a pro-healing direction, and family structure was also transformed from a dysfunctional structure to a functional one. As previously stated, family sandplay therapy with structural family therapy for families of children with emotional and behavioral disorders enhanced family strengths through improving family relationships and restoring family functions.

This study investigated the engineering characteristics of non-sintering binder-stabilized mixtures consisting of different ratios of a hardening agent(3%, 6%, 9%, 12%) for recycling industrial by-products through several series of laboratory tests. The hardening agents consisted of two kinds of non-sintering binders(NSB-1, NSB-2), which were developed by using inter-chemical reactions among blast furnace slag, phospho-gypsum, and an alkali activator. In addition, ordinary Portland cement(OPC) was used to compare the engineering characteristics of the stabilized mixture. An unconfined compressive test showed that the unconfined compressive strength increased with the curing time and mixing ratio. Experimental test results indicated that the 7-day strength of the NSB-1 mixture was similar to that of the OPC mixture. However, its 28-day strength was higher than that of the OPC mixture. The secant module of elasticity showed a range of $E_{50}=(42-109)q_u$ regardless of the agents. Based on the results of triaxial tests, the cohesion and friction angle increased with the mixing ratio.
