Structural instability and damage are caused by frost heave during the winter when atmospheric temperature maintains below $0^{\circ}C$. Frost heave is the most representative engineering characteristics of frozen ground and there are various frost susceptibility criteria. Frost susceptibility criteria can be roughly divided into three categories. First, frost susceptibility is determined from particle size distribution, which is practically useful and many countries are adopting. In this paper, several particle size distributions (PSDs) are applied to the frost susceptibility criteria but PSD seems to be not enough to determine whether soils are frost susceptible. Second, it is judged from laboratory frost heave testing results. Laboratory frost heave tests were performed with newly developed thermal controlled triaxial cell and the reliability of frost susceptibility criteria is evaluated. New testing apparatus and method are suitable to meet the existing frost susceptibility criteria. Third, it is compositive frost susceptibility criteria envelope including the particle size distribution, soil classification, and frost heave test. The compositive frost susceptibility criteria envelope should be supplemented based on additional data on various soil types.

The purpose of the present study was to investigate empirically the relationship among self-image, depression, anxiety, and social sensitivity in adolescents. 1602 normal adolescents(697 males and 905 females) responded to self report scales-Offer Self-Image Questionnaire-Revised, 3 subscales of Symptom Checklist-90-Revised. The data were analyzed with ANOVA and LISREL to examine the effect of self-image on depression, anxiety, and social sensitivity, and to test the relationship among the above 4 variables. Adolescents with low self-image showed significantly higher scores in the scales of depression, anxiety, and social sensitivity than did adolescents with high self-image. The result of LISREL showed that the low self-image leads to the emotional state of depression and anxiety, and those of depression and anxiety lead to the increase of social sensitivity, suggesting that self-image has a direct effect on depression and anxiety, and has a direct effect on social sensitivity in adolescent. These results were discussed in terms of implications for the prevention and treatment of adolescent social phobia.

The purpose of this study is to identify the mediated effects of social support in relation to college students' emotional control ability and rejection sensibility, and to provide basic data to intervene in students with high resistance sensibility. To this end, a survey of 449 university students was conducted and the hypothesis of this study was verified using a structural equation model. The analysis results are as follows. First, the relationship between emotional control ability, rejection sensibility and social support perceived by university students through correlation analysis showed significant correlation between emotional control ability, social support and rejection sensitivity. Second, in the structural model of social support in relation to emotional control ability and rejection sensibility, it was confirmed that social support played a role between emotional control ability and rejection sensibility. Based on the results of this study, some suggestions for the application and follow - up studies were discussed.

The purpose of this study is to identify the multicultural competence of university students majoring in social welfare studies and to verify the influence of human rights attitude and spiritual intelligence that affect multicultural competence using structural equation model. Spiritual intelligence was set as an independent variable and multicultural competence was set as a dependent variable. Human rights attitude was established as a mediating variable. Study subjects were 259 university students majoring in social welfare studies at 5 universities in the Daegu, Gyoungbuk area. Spiritual intelligence and human rights attitude appeared to have a significant effect on multicultural competence, indicating that a higher level of spiritual intelligence and human rights attitude were correlated with a higher level of human rights attitude. Also in the pathway of spiritual intelligence on multicultural competence, human rights attitude had a significant mediating effect. When the university student majoring in social welfare studies had a high level of spiritual intelligence including transcendence and meaning and purpose of life, their perspective on human rights which is important in the practice of social welfare affected the multicultural competence required to assist immigrants of various identities. Based on the findings of the study, it is recommended for the university students majoring in social welfare to have the "three-multi-sensitivities" including sensitivity of multicultural competence, sensitivity of spiritual intelligence, and sensitivity of human right attitude.

The purpose of the present study was to investigate the influence of rejection sensitivity on aggression and to determine the mediating role of self-esteem level and its stability. Data based on self-report questionnaires from a sample of 312(N=312) undergraduate and graduate students were analyzed using the SPSS 22.0, and the Amos 18.0. Results from the structural equation modeling indicated that rejection sensitivity had a negative impact on self-esteem level and a positive impact on self-esteem instability. Self-esteem level had a negative impact on aggression. Self-esteem instability had a positive impact on aggression. The effect of rejection sensitivity on aggression was fully mediated by self-esteem level and instability. Current findings add to the extent literature on the influence of rejection sensitivity on self-esteem level, self-esteem instability, and aggression. Implications of the present study, limitations of current study as well as suggestions for future study were also included in the discussion.

Over 100 countries have conducted research on experimental testing methods to assess the frost susceptibility of soils. This study aims to prevent structural damage caused by frost heave. Notably, the United States and Japan, which encompass cold regions such as Alaska and Hokkaido, have actively pursued frost heave research. Through laboratory investigations and field applications, standard testing methods and criteria for evaluating frost susceptibility have been established. However, these methods are complex and their engineering explanations are vague. This study closely compares and analyzes the frost-susceptibility testing methods proposed by ASTM and JGS, considering temperature conditions, specimen size, freezing direction, and drainage conditions. By conducting this comparative analysis, this study aims to shed light on the similarities and differences between the two methods. Furthermore, based on the findings, this study proposes future research guidance for refining frost-susceptibility testing methods and criteria.

Recently, the number of cases of child abuse has been increasing and, consequently, the social interest in this issue is increasing. The purpose of this study is to examine the relationship between child abuse, rejection sensitivity and emotional regulation and to identify the mediating effects of rejection sensitivity in the relationship between child abuse and emotional regulation. For this purpose, a survey on child abuse, rejection sensitivity and emotional regulation was administered to 217 elementary school students in the fourth, fifth and sixth grades, who had been reported as victims of child abuse or managed as suspected child abuse victims in the Seoul, Gyeonggi, Gangwon, Chungcheong, and Gyeongsang regions. The data was analyzed using structural equation modelling and bootstrapping. The findings showed that child abuse was significantly negatively correlated with emotional regulation, but positively correlated with rejection sensitivity. Emotional regulation was significantly negatively correlated with rejection sensitivity. Second, the structural equation analysis also revealed that rejection sensitivity fully mediated the relationship between child abuse and emotional regulation. This means that child abuse has an indirect effect on emotional regulation through rejection sensitivity. Therefore, when counseling abused children with emotional regulation problems, it is important for the counselors to include interventions designed to lower their rejection sensitivity.

An improved model for predicting the reinforced concrete element behavior under dynamic strain rates was developed using the layer modeling technique. The developed strain rate sensitive model for axial/flexural analysis of reinforced concrete elements was uses to predict the test results, performed at different loading rates, and the predictions were reasonable. The developed analysis technique was used to study the loading rate sensitivity of reinforced concrete beams and columns with different geometry and material properties. Two design formulas for computing the loading rate dependent axial and flexural strengths of reinforced concrete sections were also suggested.

Recently, urban information system(UIS) has been developed and utilized by local governments in Korea and has become a key means of urban informatization of local governments. When UIS is conducted only for FM oriented internal utilization regardless of its cost-efficiency, however, its cost-benefit structure could be distorted seriously. The study utilizes benefit cost analysis technique and applied the technique to a model case of Chungju UIS selected by National GIS team. Chungju City developed its GIS for the management of roads and urban planning in 1993. At its beginning, the system was an efficient model with relatively strong cost-benefit structure and could produce positive net benefit 10 years' after its construction. When the city began to develop its facility management with the financial assistance from central government in 1998, however, its cost-benefit structure became distorted. As a result, it is delayed for the UIS to produce positive net benefit until the year of 2015. Using benefit cost ratio, discount rate and Mobile GIS, the study also conducts a sensitivity analysis.
