Raining method has been widely used for preparing sand specimen because of its ability to reconstitute the homogeneous specimen with desired relative density and its reliability established by the numerous experiments on diverse influential factors. In conventional raining methods, adjustment of relative density is achieved by controlling the shutter porosity and the whole system is required to be re-adjusted to achieve the target relative density when the granular characteristics are changed. It is also observed from conventional methods that certain degrees of spatial variation in density exist and the limited range of relative density is reproduced. In this paper, raining system with porous plate is proposed. It is shown that the wide range of relative density can be achieved by controlling failing height only. This enhanced system is able to obviate the subtle control of shutter porosity and minimize the effect of falling distance, which in turn ensures the homogeneity of the specimen, especially for low relative density.

This study investigated work experience of firefighters and risk factors for their depression during COVID-19 pandemic. We analyzed data of 53,557 firefighters who participated in the online mental health status survey. Data included experiences of COVID-19 infection, experience of COVID-19 response work, fear of social stigma, and anxiety and depression symptoms. Results showed that 45.76% of participants had experience of COVID-19 response work. Emergency job group had the highest percentage of COVID-19 related work and the greater intensity of the work and fear of social stigma than those of other job groups. Hierarchical multiple regression showed that co-workers' infection, COVID-19 related work intensity and fear of social stigma were significantly associated to the severity of depression. The findings in this study demonstrated COVID-19 related work experience can link to the development of depression in firefighters. Effort to reduce COVID-19 related work intensity and fear of social stigma could help prevent depression among firefighters.

Purpose: With the implementation of the Act on Life Sustaining Treatment, hospice-palliative care will be extended to non-cancer diseases including the acquired immunodeficiency syndrome (AIDS). However, there are concerns about negative perceptions and prejudice toward AIDS patients. The purpose of this study was to investigate factors related with willingness to volunteer (WV) for patients with end-stage AIDS among hospice volunteers. Methods: Participants were 326 hospice volunteers from 19 institutions. A self-administered questionnaire was employed to investigate the participants' WV for end-stage AIDS patients, and the questions were answered using an 11-point rating scale. Demographics, volunteer activity, satisfaction with hospice volunteering, knowledge of AIDS, and attitudes towards AIDS patients (i.e., fear AIDS patients, negative attitude towards AIDS patients, personal stigmatization and stigmatizing attitude) were also investigated. A multiple regression analysis was performed to examine factors associated with WV for patients with end-stage AIDS. Results: WV for patients with end-stage AIDS was 2.82 points lower than that for cancer patients (P<0.001). The multiple regression analysis showed that the higher the level of satisfaction with hospice volunteering (P=0.002) and the lower the level of "personal stigmatization" (P<0.001), participants showed greater WV for end-stage AIDS patients. Conclusion: The level of satisfaction with hospice volunteering and "personal stigmatization" were factors associated with participants' WV for patients with end-stage AIDS.

This study analyzed the experiences of victims of state violence, discovered differences between state violence and general trauma, and proposed ways to help heal trauma. Participants were composed of state violence victims and their families in total, including 11 from the Jeju 43 Incident, 11 from the Yeos u·Sunchoen 10.19 Incident and 6 form May 18th Democratic Uprising. As a result of using the grounded theory to analyze data, a total of 170 concepts, 57 subcategories, and 20 categories were derived. The central phenomenon was direct damage caused by state violence. This included 'post-traumatic stress', 'social stigma', 'isolation from community', 'socio-economical issues' and 'family dissolution'. As a result of the process analysis, the participants experienced six phases: 'trauma', 'isolation', 'resistance', 'resignation', 'recovery', and 'growth.' Each phase is sequential but at the time mutually affect each other. Based on the results, this study verified the difference between state violence and general trauma, and emphasized social and cultural factors, such as community support, were important factors in healing state violence trauma. Besides, the implications and limitations as well as suggestions for future research were mentioned.

The purpose of this study is to analyze the cognizance of North Korean refugee by applying Q methodology, as well as to provide preliminary data for improving North Korean refugee's image. The study process let P sample, the study participants, use Q-sorting methodology to sort Q sample, which is composed of statements. 18 participants sorted 32 statements and 3 types of North Korean refugee cognizance were produced as a result. Those types are 1(N=8), 2(N=6), and 3(N=4), which are type favorable, type whereas negative stereotypical, and type neutralist. Favorable types agreed to ensure North Korean refugee groups' rights as a general protection, whereas negative stereotypical types had strong discrimination and prejudice towards North Korean refugee groups due to lack of related knowledge. Furthermore, neutralist types showed an objection to negative stereotypes against North Korean refugee, but they did not entirely agree to North Korean refugee either. It is necessary to develop a detailed strategy to improve the social image of North Korean refugee.

This study conducted a meta-analysis to examine syntagmatically on the variables related with recovery among persons with mental illness in Korea. In order to do a meta-analysis, theses and dissertations published between 1999 and 2018 in Korea were reviewed systematically and a total of 24 including studies were selected. Using Comprehensive Meta Analysis (CMA) 3.0 software, this study calculated average effect size and moderator variables related with recovery among persons with mental illness. Results were as follows. First, this study identified a total of 16 variables related with recovery among persons with mental illness. Second, the results indicated that variables which showed large effect sizes included social support(r=.575), empowerment(r=.555), self-efficacy(r=.544), social skill(r=.500), relationship with social worker(r=.482), stigma(r=-.446), family support(r=.418). Third, variables with medium effect sizes included interpersonal relationship capacity (r=.391), agency service satisfaction(r=.366), insight(r=.373) and symptom(r=-.239). Fourth, variables with small effect sizes included work experience(r=.188). Fifth, moderator analyses were conducted utilizing characteristics of residence state (community or mental hospital). Moderator effects were identified in the social support and family support. Based on the findings, theoretical and clinical implications for the recovery among persons with mental illness in Korea were discussed.

This article attempted to find out the moderating effects of social support in the relationship between perceived stigma, depression of student with disabilities(SWD) and their adjustment of campus life. For the purpose of the reason the data were collected from 108 SWD from questionaries in Busan city and Kyungnam province. The results were as follows. It was revealed that the factors, grade and gender, had significant difference in the level of adjusting campus life of SWD. Perceived stigma and depression of SWD had positive impact on the adjustment of campus life. Social support of SWD also had positive impact on the adjustment of campus life. This study demonstrated that social support of SWD had moderating effect in the relationship between perceived stigma, depression of SWD and their adjustment of campus life. This study verified that for the purpose of improving the adjusting level in college life of SWD, it was as important to make social support to be delivered at SWD as decreasing the perceived stigma and depression of SWD. Finally, the authors suggested some direction to solve the problem related this study question and remarked the limitation of this study.

This study used laten class growth analysis to identify discrete developmental patterns of delinquent behaviors in adolescence. This present article also examined associations among these trajectories to determine how the development of delinquent behaviors relates to protective and risk factors, which include parental monitoring, attachment with parent, association with deviant peers, self-control, and negative stigma from others. Four-wave panel data from a Korea Youth Panel Study were used for the latent class growth model analysis. The sample consisted of 3,446 adolescents who were assessed at 4 measurement waves with approximately 1-year interval. Four trajectories of delinquent behaviors emerged: delinquency persistence, delinquency increaser, delinquency decreaser, normative group(almost no delinquent behaviors). Association with deviant peers had the most proximal strong influence on the probability of being in the delinquency increaser and delinquency persistence group compared, noed to the normative group. Parental monitoring, self-efficacy and negative stigma also differentiated the four delinquent behavior trajectories from one another after controllig for socio-demographic variables. The study suggested that there is a significant heterogeneity in the timing and change rate of delinquency progression. Adolescent delinquency prevention and intervention programs will need to consider this heterogeneity and enhance attention to protective and risk factors depending on the subpopulation.

This study aimed to understand the interrelationships between tree species in plant communities through Plant Social Network (PSN) analysis using a large amount of vegetation data surveyed in an island area belonging to a warm-temperate boreal forest. The Machilus thunbergii, Castanopsis sieboldii, and Ligustrum japonicum, which belong to the canopy layer, Pittosporum tobira and Ardisia japonica, which belong to the shrub layer and Trachelospermum asiaticum and Stauntonia hexaphylla, which belong to the vines, appearing in evergreen broad-leaved climax forest community, showed strong positive association(+) with each other. These tree species had a negative association or no friendly relationship with deciduous broad-leaved species due to the large difference in location environments. Divided into 4 group modularizations in the PSN sociogram, evergreen broad-leaved tree species in Group I and deciduous broad-leaved tree species in Group II showed high centrality and connectivity. It was analyzed that the arrangement of tree species (nodes) and the degree of connection (grouping) of the sociogram can indirectly estimate environmental factors and characteristics of plant communities like DCA. Tree species with high centrality and influence in the PSN included T. asiaticum, Eurya japonica, Lindera obtusiloba, and Styrax japonicus. These tree species are common with a wide range of ecological niches and appear to have the characteristics and survival strategies of opportunistic species that commonly appear in forest gaps and damaged areas. They will play a major role in inter-species interactions and structural and functional changes in plant communities. In the future, long-term research and in-depth discussions are needed to determine how these species actually influence plant community changes through interactions
