철근콘크리트 구조물은 타설 후 시간이 경과함에 따라 물리적인 요인과 화학적인 요인으로 인하여 열화가 진행된다. 열화된 구조물의 효율적인 구조해석을 수행하기 위하여 구조물의 거동과 밀접한 관련이 있는 중요열화변수를 정의하는 것은 필요하다. 본 연구에서는 경년열화된 철근콘크리트 전단벽의 중요변수를 분석하기 위하여 일계이차모멘트법을 이용하여 민감도해석을 수행하였다. 콘크리트의 경화현상을 고려하지 않을 경우 구조물의 열화성능이 과소평가될 수 있으므로 콘크리트의 경화에 따른 해석변수들의 민감도를 분석하였다. 열화된 전단벽에서 변수의 중요도는 토네이도 다이어그램으로 나타내었다.

The purpose of this research was to analyze the relationship between environment-friendly housing behaviors and the influential variables among consumers by focusing on housing life. This research carried out a questionnaire survey with housewives living in Seoul and the Metropolitan area using a questionnaire that was composed based on previous research. The housewives' environment-friendly housing attitudes and their resource-saving knowledge level, along with environmental education-related variables, house ownership, and the housewives' employment appeared to be significant variables in explaining the generic environment-friendly housing behaviors found in this research. Three regression equations, classified into purchasing, utilization, and disposal behaviors, were employed. The empirical results were relatively similar to those for the generic environment-friendly housing behaviors; however, each model provided somewhat different results in some specific aspects. All the environmental education-related variables appeared to be significant in explaining environment-friendly housing utilization behaviors, and were similar to the results obtained from the generic environment-friendly housing behaviors. However, the variables were limited in explaining environment-friendly housing-related disposal behaviors. The convenience, recycling ease, and family-structure variables appeared to be significant influences on environment-friendly housing-related disposal behaviors. Most empirical results of this research were consistent with those of previous studies. However, the explanatory independent variables varied, depending on the types of each domain of environment-friendly housing behaviors studied.

Purpose: This study aimed to develop a scale to measure variables related to alcohol drinking prevention behavior in early elementary school, based on the theory of planned behavior. Methods: A scale was developed to measure variables related to alcohol drinking prevention behavior. Initial items for direct evaluation were constructed through a literature review, and those for belief-based indirect measure were generated through interviews with 30 second- and third-grade elementary school students. The collected data from 286 third-grade elementary school students were then subjected to item analysis, exploratory and confirmative factor analysis, criterion-related validity testing, and internal consistency assessment. Results: The final scale consisted of 35 items. Intention, attitudes, subjective norms, and perceived behavioral control explained 82.7% of the variance; behavioral beliefs, normative beliefs, and control beliefs explained 65.6% of the variance; and evaluation of outcome, motivation to comply, and power of control beliefs explained 72.8% of the variance. The confirmatory factor analysis indicated that the theoretical models had a satisfactory goodness of fit. Criterion-related validity was confirmed between the direct evaluation variables and the indirect measure variables (attitudes r=.64, p<.001; subjective norms r=.39, p<.001; perceived behavioral control r=.62, p<.001). Cronbach's α was .89 for the direct evaluation variables and .93 for the indirect measure variables. Conclusion: The scale developed in this study is valid and reliable. It could be used to measure and explain variables related to alcohol drinking prevention behavior in early elementary school.

Using the second year data of the Korean Child and Youth Panel Survey (KCYPS) elementary 4 panel, this study attempted to elucidate variables related to elementary school 5th graders' life satisfaction and how the variables are clustered in each gender. Analyzing the data of 2378 5th graders (boys 1180, girls 1084) indicated that variables related to their life satisfaction were self-esteem, parenting style, peer attachment, grade satisfaction, and school adjustment. Both boys and girls were clustered into three clusters. The cluster 1 children indicated the highest degrees of self-esteem, peer attachment, grade satisfaction and school adjustment levels, and they perceived parenting style more positively than the children from the other clusters. The cluster 3 children showed the opposite trends to the cluster 1 children in each of the five variables and the cluster 2 showed middle levels in all of the variables. The characteristics of the three clusters were analyzed in terms of the differences of children's life satisfaction and explanatory variables of life satisfaction.

The purpose of this study is to synthesize research findings on the relationship between parenting efficacy and the variables related to it, as well as to produce results using meta-analysis. The following questions guide this study : Which variables are frequently conducted in research related to parenting efficacy? What is the effect size of each variable? The 65 studies whose results are analyzed in this paper were collected via a search for investigations focusing on 'parenting efficacy'. The studies were used for meta-analysis in which eleven variables were selected. The results of the analysis indicate that a large effect size is produced by the parenting stress in a negative direction. A higher than medium effect size occurs on the basis of parenting beliefs in a negative direction. A higher than medium effect size is also caused by the father's involvement in child care and social support. A medium effect size is produced on the basis of children's temperament, and a small effect size is the result of the mother's academic background, parenting knowledge, and parent's income. There is no relationship between parenting efficacy and children's gender.

Objective: This study aimed to examine parenting education participation of Korean mothers in the transition to parenthood and its related variables. Method: A study sample was composed of 870 mothers whose first child was younger than one-year old from the Panel Study on Korean Children in 2008(mean age=30.1, SD = 3.69). The descriptive statistics of parenting education participation were presented. In addition, negative binomial and logistic regression models were used in Stata13 in order to examine the variables related to parenting education participation of mothers in the transition to parenthood. Results: Approximately 82% of the mothers reported that they had participated in at least one parenting education program. Further, mother's educational level, monthly household income, mother's working experience, and community type generally predicted parenting education participation of mothers. However, the effects of these variables varied by the subjects and the providing institutions. Conclusion: This study provides the overall picture of parenting education participation of Korean mothers in the transition to parenthood and its related variables. The findings can be utilized to plan more effective parenting education programs for new parents.

The aim of this study is to find the relationship between interictal psychiatric symptoms and seizure-related variables such as structural changes, regional interictal perfusion changes, the number of interictal epileptic discharges and the presence of accompanying generalized tonic clonic seizure(GTC). The subjects were 75 patients (47 males : mean age $28.3{\pm}7.7$) with intractable epilepsy, Interictal psychiatric symptoms were rated by Symptom Checklist-90-R(SCL-90-R). Each of 4 seizure variables was measured by MRI, $^{99m}TC-HMPAO$ SPECT and the prolonged EEG monitoring. The mean SCL-90-R subscale T-scores and the ratio of the patients with definite psychiatric symptoms(T-score > 65 at any one subscale of SCL-90-R) were compared among the groups with different seizure variables. Demographic variables and clinical variables were not statistically different among the groups with different seizure variables. The patients with right mesial temporal sclerosis had higher mean SCL-90-R scores for obsessive compulsive symptom, interpersonal sensitivity, depression, hostility and psychotic symptoms than the patients with left mesial temporal sclerosis, and they also showed higher ratio of definite psychiatric symptoms. The presence of interictal epileptic discharges was related with higher T-scores of paranoid subscale. The areas of hypoperfusion, the presence of the GTC, and other clinical seizure variables showed no significant influences on the mean SCL-90-R subscale T-scores. from these results, the authors speculated that interictal subictal epileptic dischrages may be related with psychiatric symptoms of the intractable epileptic patients, especially with right mesial temporal sclerosis.
