As the development of urbanization has cause some environmental problems and natural disasters such as natural earthquakes and floods have brought about impact, designers have turned their attention to the independent prevention ability of urban ecosystems in face of environmental pollution and natural disasters, as well as its ability to adapt to the future. This study introduces 'elasticity theory' to discuss the practical application of elasticity design in landscapes and to solve the problem of lack of elasticity in space, which can provide more scientific reference meaning to create economic, cultural, and social values for space. After selecting 'The High Line' as the object, this paper investigates the previous theories and practical cases, and infers ecology, sustainability, diversity, and adaptability. And then this paper applies five components and analyzes the specific application of these five components of the landscape spatial elasticity strategy, and summarizes the application characteristics and influencing factors of elasticity design in 'The High Line' landscape planning. It can be known from the research that elasticity strategy which is reflected in the design process is the systematic management of landscape space. Elasticity design itself can strengthen environment quality and satisfy the requirements of the environment to defense external shocks so as to adapt to environment changes. Therefore, the elasticity design can strengthen the sustainable development of the city and establish a periodic recycle system.

This study aims to explore the variables which determine performance of inter-firm R&D cooperation. As the dependent variable is categorical - whether the new product developed by the inter-firm cooperation were sold or not-and the independent variables were interval, discriminant analysis was used. The independent variables were composed of degree of inter-firm cooperation, experience of cooperation, market attractiveness, R&D intensity, resources and competences of enterprise and efficiency of government support. A total of 144 responses were obtained. The results indicate that the degree or inter-firm cooperation is the best predictor of the performance, followed by market attractiveness, R&D intensity and resources/competences of enterprises. Whereas, the experience of cooperation and efficiency of government support program were not statistically significant predictors. The hit ratio or the percentage of cases correctly classified was 66.2%. We derived several implications of these findings in an effort to guide subsequent inquiry.

The purpose of this study was to examine the awareness of dental hygiene students on sexual harrassment in an effort to provide some information on the prevention of sexual harrassment. The subjects in this study were 738 dental hygiene students at colleges located in four different large regions. As for the concept of sexual harrassment, the students got 4.33 out of a possible five in that regard, which was a high score. But they got a relatively lower score of 3.42 in awareness of the causes of sexual harrassment. They got the highest score of 4.42 in physical sexual harrassment among different types of sexual harrassment. Regarding the offender of sexual harrassment, they got 2.81 out of a possible five, which was lowest among their scores in the items of sexual harrassment awareness. There were statistically significant differences in sexual harrassment awareness according to gender, age, grade and religion. The above-mentioned findings of the study illustrated that the dental hygiene students were well aware of sexual harrassment in general, but that the way they coped with it was quite passive. The development of educational programs on how to prevent sexual harrassment and cope with it is required to spread better awareness of sexual harrassment among college students and to encourage them to properly cope with it.

This study aims to investigate the aspect of volunteering and donation of highschool students in Seongnam city and further the relationship between volunteering and democratic civic consciousness. To that end, 155 students from an ordinary highschool and a foreign language highschool participated in a survey. The result showed that female students' participation rates of volunteering and monetary donations were higher than male students' but there was no difference in the participation rates between the schools. The civic consciousness level was not affected by the gender, but was affected by the schools. The scores for the attitude of democracy were better than those for the value and the participation of democracy. In particular, the students from the foreign language highschool had higher scores for the participation of democracy relative to the students from the highschool. As for the relationship between volunteering and democratic civic consciousness, there was a significant difference in civic consciousness scores between students who had participated in volunteering and those who had not, only in the case of the students from the ordinary highschool. Additionally, it was revealed volunteering and donating were compensatory behavior. Although single factors in volunteering influencing the civic consciousness were not found, persistence was important.

The purpose of the study was to investigate the effect of stress, social support, and self-esteem on depression in female students. A self-reported questionnaire was completed by 249 females students from November to December 2015. The study instruments comprised stress, social support, self-esteem, and depression. The data were analyzed by descriptive statistics, t-test, ANOVA, Pearson's correlation coefficients, and hierarchial multiple linear regression using SPSS/WIN 18.0 program. Depression was closely related to school year(F=7.03, p<.001), health status(F=15.19, p<.001), major satisfaction(F=18.02, p<.001), and student activity(t=1.98, p=.049). The significant factors influencing depression were stress(${\beta}=.45$, p<.001), self-esteem(${\beta}=-.34$, p<.001), social support(${\beta}=-.14$, p=.004), major satisfaction(${\beta}=-.11$, p=.018). To decrease depression, it is necessary to develop a program coping with stress and increasing the self-esteem and social support. Thus, it will be able to enhance the mental health of female students.

The ultimate objective of periodontal therapy is not only stopping the progression of periodontal disease, but also promoting the regeneration of lost periodontal tissue. Guided Tissue Regeneration, which is based on the principle that the goal of periodontal regeneration can be achieved by preventing apical migration of gingival epithelium and blocking cells originating from connective tissue, has been developed and used as a clinical procedure, and although it has shown excellent results in connective tissue healing, there have not been many studies showing its effect on the regeneration of alveolar bone loss due to periodontal disease. The objectives of this study are to investigate the result of 12 months-long treatment following guided tissue regeneration using expanded polytetrafluoroehylene membrane, and to observe the presence of regenerated alveolar bone. Forty-one teeth from 28 patients with clinical diagnosis of periodontitis has been selected. In fifteen of those interproximal intrabony defects, only flap operation had been carried out, and designated as the control group. Twenty-six intrabony defects received e-PTFE membrane following flap operation, and designated as the experimental group. Eleven teeth whose membrane had been exposed were excluded from the experiment. Various measurements including probing depth, loss of attachment, probing bone level and gingival recession have been recorded at 6th month and 12th month, and the significance of the changes has been analyzed. The results are as follows: 1. Probing depth at 6th and 12th month has shown a significant decrease in both groups (p<0.01), but significantly higher decrease was found in the experimental group compared to the control at the month(p<0.05). 2. Loss of attachment at 6th and 12th month has shown a significant decrease in both groups, but significantly higher decrease was found in the experimental group compared to the control (p<0.05). 3. Probing bone level at 6th and 12th month has shown a insignificant decrease in the control group and significant decrease in the experimental group (p<0.01). Significantly higher decrease in probing bone level was found in the experimental group (p<0.05). 4. Gingival recession at 6th and 12th month has shown a statistically significant increase (p<0.05), and the control group showed higher increase compared to the experimental group although no statistical significance was found. As these results have shown, the use of e-PTFE membrane in intrabony pockets results in marked decrease in the loss of attachment and probing bone level. This seems to indicate that e-PTFE membrane may play a role in alveolar bone regeneration in intrabony defects.

Regeneration of periodontal tissue after a loss of attachment due to disease or trauma repesents an important issue in dentistry, and various bone graft materials have been used to regenerated lost periodontal tissue and restore proper fuctions. Among those, allografts have been extensively researched and widely used clinically, since they are known to possess an excellent osteoinduction capability and result in proper topography of alveolar bone. Regeneration of periodontal tissue in supraalveolar defects may be technically difficult. However, a large amount of regeneration has been observed by complete tissue coverage of involved teeth. In this study, supraalveolar defects in adult dogs were treated with periodontal surgery, decalcified freez-dried bone allograft, complete tissue coverage was attained, and effects on repair and regeneration of alveolar bone, cementum and periodontal ligament were studied. Exposure of premolar furcation of adult dogs was attained by removing marginal alveolar bone down to 5mm from CEJ, and root surfaces were planed with curettes. On the left side, defects were treated without any allograft(Control Group). On the right side, a DFDB was used(Experimental Group). In all groups, flaps were coronally positioned and sutured, completely submerging the treated defects. At two weeks, the crown were exposed 2-3mm. Healing progresses were histologically observed after eight weeks and the results were as follows : 1. Distance from CEJ to AJE was : $2.82{\pm}0.66mm$ in the control group, $1.71{\pm}0.51mm$ in experimental group, with significant differences between groups.(P<0.01) 2. Periodontal repair was : $2.18{\pm}0.66mm$ in the control group, $3.29{\pm}0.51mm$ in experimental group, with significant differences between groups.(P<0.01) 3. Connective tissue repair was : $1.43{\pm}0.52mm$ in the control group, $0.76{\pm}0.47mm$ in experimental group, with significant differences between groups.(P<0.01) Orientation of connective tissue fibers in relation to root surfaces was : mostly parallel in the control group, vertical or parallel or irregular in experimental group. 4. The amount of cementum formation was : $1.66{\pm}0.58mm$ in the control group, $2.86{\pm}0.66mm$ in experimental group, with significant differences between groups. 5. The amount of alveolar bone formation was : $0.76{\pm}0.72mm$ in the control group, $2.53{\pm}0.56mm$ in experimental group, with significant differences between groups.(P<0.01)
