We tried to blend PLLA and PDLA at overall compositions to form PLA stereocomplexes (SC). The presence of the SC crystalline phase in the PLLA matrix was verified by differential scanning calorimetry (DSC). As a result, a various PDLA composition of the PLA SC blends can influence PLA SC formation. And the largest amount of PLA SC crystallites was formed when PLLA/PDLA ratio is 50/50. In addition, we have tried to do PLA SC toughening with two impact modifiers in 92/8, 85/15 ratio of PLLA/PDLA to enhance the mechanical properties such as impact strength. Thermal and mechanical properties of PLA SC were investigated by DSC, HDT, Izod impact tester and UTM. PLA SC formation decreased when 10-20 wt% of Strong120 (impact modifier) was added. On the other hand, there is no effect on PLA SC formation when 10-20% of Elvaloy (impact modifier) was added. HDT values dramatically increased over $100^{\circ}C$ with the addition of PDLA. However, HDT decreased as Strong120 and Elvaloy content increased. Finally, we could find well balanced composition of toughened PLA SC with 10wt% of impact modifier in flexural modulus and impact strength.

Purpose: The purpose of this study was to identify the impact of academic stress on depression suffered by college nursing students and the moderating effects of academic resilience. Methods: For this survey, 257 students (1st and 2nd year) participated, and it was performed over two weeks in September 2014. In this study, statistical analysis was conducted using SPSS 18.0 for Windows and as a t-test, ANOVA, Pearson correlation, and multiple regression analysis. Results: The students' academic stress had a significant impact on their depression (${\beta}=.279$). The moderating effects of academic resilience did not have a significant impact, which is presumably as a result of there being more complex, nonlinear effects, rather than a simple, linear relationship between academic stress and resilience. Conclusion: It may be incorrect to assume that academic resilience is a moderating variable that lessens academic stress. It is implied that academic resilience can have a significant impact when internal and external support conditions are met, and that the effects can be reinforced when family support, a learning environment, and improved adaptability to life at school are also provided.

The purpose of this study is to examine the impact of social voluntary activity on the identity of women's college students. universities are functionally constituted by teaching, researching and social service. Data for analysis are collected 439 students at K women's college in other to examine research questions, t-test and regression test. The results of this analysis are as follows : First, There was any gap in self-esteem, morality and social welfare ideology between the college students who had ever experienced social voluntary activity and who had not. Second, The personal characteristics did not give an impact, but their satisfaction was under the influence of institutional support for supervision and altitude of themselves for social service, which were part of the institution characteristics. Third, The social service effectiveness was not affected by the personal characteristics, except influenced by the instituitional characteristits such as degree of compensation an influence on self-esteem. also social welfare and morality were not affected. Fourth, There was any gap in self-esteem, morality and social welfare ideology between the impact of service satisfaction on service effectiveness.

Objective: This study aimed to introduce Health Impact Assessment using the case of a HIA on 2008 Dream Start Project in Cheongju. Methods: We followed the typical procedure of HIA recommended by the Merseyside Guidelines on HIA. In scoping, the steering committee decided 5 key domains of child health to be assessed: prenatal care, vaccination, nutrition, access to health care, and child abuse and also the methods of collecting the evidence. The HIA appraisal team collected information from various sources including literature, community survey, and focus group interviews. The HIA appraisal team also synthesized the collected information in terms of the nature of health impacts and equity and made recommendations accordingly. Results: Positive impacts were expected in prenatal care, vaccination, and nutrition, while negative impacts were expected in access to health care. The impact of Dream Start on child abuse was uncertain. Several recommendations were made and submitted to the Dream Start team for their consideration. About 2 years later, we found many of them were implemented in 2009 Dream Start project. Conclusion: HIA was found to be applicable and effective to make decision makers in the welfare sector consider health in their work.

Objective: The purpose of this research was to establish the differences of ground reaction force variables and sensations according to the foot types and the structures of the inner arch support band during $2^{nd}$ vertical ballet jump. Method: 12 Female ballet majors in their twenties who have danced for more than 10 years and had no injuries were selected for this research. Independent variables consist of the foot type (pes rectus, pes planus) and the structure of the inner arch support band (no band, x-shaped, linear shaped). Dependent variables consist of ground reaction force variables and relative wearing sensation. Results: The impact decreased the most when x-shaped bands were used on pes rectus and rigid pes planus. When linear-shaped bands were used on flexible pes planus, the impact decreased. Conclusion: The bands also helped reduce the impact on pes rectus. Furthermore, it is clear that according to the foot type, the impact reducing band structures perform differently. The inner arch support bands were necessary for jump training for any foot type.

The main objective of this study was to investigate the impact of access to finance on the different dimensions of poverty. To achieve the objectives of the study, the participants/beneficiaries of the Mudra scheme were included and sample of target respondents was extracted through multistage random sampling technique. The sample for the study was taken from the Union Territory of Jammu and Kashmir of India. The study further utilized secondary data from the government official websites and lead banks. A paired t-test was applied to test the impact of access to finance across the various dimensions of poverty by constructing the Multidimensional Poverty Index(MPI), after checking the normality of the data. MPI incorporates dimensions such as education, health, and standard of living.The finding of the study revealed that dimensions of poverty responded positively to access to finance. The study shows that larger access to finance has helped in reducing the multidimensional poverty by having moderate, but positive impact on the standard of living, health, and education, thereby improving the lives of the poor. The present study identified that the level of impact of access to finance is moderate and further explains its importance for policy implications.

The purpose of this study was to determine the impact of demographics on body-cathexis and clothing expenditure of elderly men and women. Data were obtained from 50 men and 58 men and 58 women aged 55 years and older through an mail survey. Body-cathexis consisted of five areas of body parts: head/upper body, lower body, height, weight, and torso. Clothing expenditure was measured by the total dollar value of annual personal expenditures on personal apparel, including accessories, such as shoes, and clothing services. Demographics included income, age, education, sex, marital status, and social participation. Data were analyzed using multiple regression. The results showed that there were relationships between body-cathexis and four demographic variables(income, sex, education, and social participation). Elderly men were more satisfied with their bodies than were elderly women. The subjects with higher income, education, and social participation had a higher degree of body satisfaction. Also, there was a significant relationship between income and clothing expenditure.
