In this paper, reinforcement of soil shear strength by bamboo(substitute materials simulating a root system) are evaluated by soil strength parameters(apparent cohesion(c) and internal friction angle(tan${\Phi}$)), using simple shear tester which clearly depicts shear deformation and controls soil suction. The results show that the internal friction angle does not change under various soil suction conditions but the apparent cohesion, which reach a peak in suction of 45cm$H_2O$ near critical capillary head, is effected by soil suction. And the reinforcement of soil strength by bamboo are expressed by apparent cohesion more than internal friction angle. In addition the increment of apparent cohesion by bamboo reached a peak in suction 45cm$H_2O$ too.

Many researchers have evaluated the influence of vegetation cover on slope stability. However, due to the extensive variety of site conditions and vegetation types, different studies have often provided inconsistent results, especially when evaluating in different regions. Therefore, additional studies need to be conducted to identify the positive impacts of vegetation cover for slope stabilization. This study used the Transient Rainfall Infiltration and Grid-based Regional Slope-stability Model (TRIGRS) to predict the occurrence of landslides in a watershed in Jinbu-Myeon, Pyeongchang-gun, Korea. The influence of vegetation cover was assessed by spatially and temporally comparing the predicted landslides corresponding to multiple trials of cohesion values (which include the role of root cohesion) and real observed landslide scars to back-calculate the contribution of vegetation cover to slope stabilization. The lower bound of cohesion was defined based on the fact that there are no unstable cells in the raster stability map at initial conditions, and the modified success rate was used to evaluate the model performance. In the next step, the most reliable value representing the contribution of vegetation cover in the study area was applied for landslide assessment. The analyzed results showed that the role of vegetation cover could be replaced by increasing the soil cohesion by 3.8 kPa. Without considering the influence of vegetation cover, a large area of the studied watershed is unconditionally unstable in the initial condition. However, when tree root cohesion is taken into account, the model produces more realistic results with about 76.7% of observed unstable cells and 78.6% of observed stable cells being well predicted.

The purpose of this study was to identify the moderating effect of resilience and hope among satisfaction of university, family cohesion, and perceived entrapment. It was conducted to measure research variables from 610 university students. The moderating effect according to resilience and hope was analyzed through hierarchical regression analysis and presented in graphs of significant moderating effect. As a result of analysis, first, there were significant relationship, among satisfaction of university, family cohesion, and perceived entrapment. Second, satisfaction of university and family cohesion had a significant negative effect on the perceived entrapment. Third, resilience had moderating effect within the relationship of university satisfaction and perceived entrapment. Forth, hope had moderating effect within the relationship of family cohesion and perceived entrapment. Implications of these results were explored in relation to the importance of resilience and hope that could be taken to reduce perceived entrapment.

This research aimed to verify whether family competency reinforcement had a mediating role on the effect of family cohesion of the Down syndrome family upon the independent life of children with Down syndrome. For the research, 146 families belonged to Down Syndrome Parent Assembly were surveyed and the statistical program SPSS WIN 25.0 was utilized for the data analysis. To verify the mediating effect, Baron and Kenny's causal step strategy was performed. As a result of the study, the higher the family cohesion of the Down syndrome family was, the greater the level of independence of the child was, indicating that the family cohesion had a significant static effect on the independence life. In addition, it was confirmed that the family competency reinforcement played a mediating role between the family cohesion and the children's independent living. Therefore, the results of this research suggested that it might be used as a policy approach and supporting plan for the realization of support for independence of Down syndrome children.

The purpose of this study was to investigate the effect of weekend forest healing programs using urban forest on family cohesion and family relationship improvement and parental satisfaction with programs. 21 families (65 people)participated in the weekend forest healing program in Incheon Grand Park from April to August 2018. The program using family forest experience activity and forest healing therapy was newly constructed and implemented with 4 times 8 hours for 2 hours each week. The results of this study is that weekend forest healing programs for family gave a positive effect on family cohesion and family relationship, and parents' satisfaction showed high satisfaction in most items. Therefore, we concluded that forest healing activities are suitable for effective healing activities in modern society where functions such as family cohesion and emotional bond are recognized as important by improving family cohesion and family relationship. Further research should be extended to different types of families, and the development of diverse and interesting family-experience forest healing programs that reflect family needs should continue.

This study examined the effect of family cohesion and perception of age-friendly environment on sense of community and the mediating role of perception of age-integration in those relationships by regions. To that end, we used survey data collected from a nation-wide survey from adults who are aged 20 to 85 (N=1,200). ANOVA, structural equation models and bootstrapping mediation tests were conducted. The results showed that family cohesion and one sub-dimension of the age-friendly environment- social participation- increased sense of community in all three regions. Also, perception of age-integration partially mediated the relationship between family cohesion and sense of community in the Metropolitan areas and small cities as well as the relationship between social participation and sense of community in all three regions. Based on the results, authors discussed ways to increase family cohesion and social participation to enhance sense of community.

In this study, to propose simplified methods for estimating the cohesion and internal friction angle of volcanic rocks in Jeju Island using uniaxial compressive strength and/or Brazilian tensile strength, the estimated values of cohesion and internal friction angle from triaxial and uniaxial compression tests and Brazilian tests were compared in terms of estimation accuracy. This study proposed simplified methods for estimating the cohesion and internal friction angle using the uniaxial compressive strength and/or Brazilian tensile strength of volcanic rocks in Jeju Island. According to the findings, among the proposed simplified methods, the method using uniaxil compressive strength was most desirable to accurately estimate the cohesion and internal friction angle of volcanic intact rocks in Jeju Island.

The purpose of this study was to investigate the effect of additives on the powder characteristics of peonja dry elixir. Peonja dry elixirs were prepared with various amounts of dextrin using a spray-dryer, and their powder characteristics such as flow, cohesion and compressibility were evaluated as an angle of repose, cohesion index and compressibility index, respectively. Their powder characteristics were not significantly different from one another, indicating that the hydrophilic dextrin, a base of dry elixir hardly affected their powder characteristics. Peonja dry elixirs were prepared with 10% dextrin and various amounts of additives such as mannitol (hydrophilic excipient), sodium lauryl sulfate (surfactant), colloidal silica (hydrophobic excipient) and HPMC (polymer), respectively, and their angle of repose, cohesion index and compressibility index were measured. The powder characteristics of peonja dry elixirs prepared with mannitol were not significantly different from one another, indicating that the mannitol scarcely improved the powder characteristics of peonja dry elixirs. The angle of repose and cohesion index of peonja dry elixirs significantly decreased with increasing amount of sodium lauryl sulfate to 0.3% followed by no significant changes in them. The cohesion index of peonja dry elixir significantly decreased with increasing amount of colloidal silica. The angle of repose and cohesion index of peonja dry elixir significantly decreased with increasing amount of HPMC to 0.3% followed by an abrupt increase in them. However, the compressibility index of peonja dry elixir significantly increased with increasing amount of HPMC to 0.3% followed by an abrupt decrease in them. Our results suggested that a small amount of sodium lauryl sulfate, colloidal silica and HPMC improved markedly the powder characteristics of peonja dry elixirs due to forming stronger and less hygroscopic shell of peonja dry elixirs. Among the peonja dry elixirs studied, the peonja dry elixir prepared with 0.3% sodium lauryl sulfate and 0.3% HPMC had the lowest angle of repose of $27^{\circ}$ and cohesion index of 37.8%, and the highest compressibility index of 38.7%, respectively. Thus, sodium lauryl sulfate and HPMC appear to be promising additives for peonja dry elixir, if used in adequate amounts.
