Periapical lesions are developed as a result of inflammatory response to irritants from root canal system. Clinicians remove these irritants from root canal system and seal the root canal space to induce healing of the periapical lesions. Immunopathologic responses may play an important role in development and progression of periapical lesions and periapical lesions contain immunocompetent cells. The purposes of the present study were to analys and to compare the distribution of the immunocompetent cells in the human periapical lesions according to the stage of endodontic treatment using indirect immunoperoxdase technique. Obtained 94 human periapical lesions were devided into four groups: Group 1 : no endodontic treatment(28 samples) Group 2 : root canal enlarged and irrigated(28 samples) Group 3 : root canal filled(29 samples) Group 4: unknown(9 samples) Monoclonal antibodies to examine target cells were UCHL-1 for T lymphocytes(1 : 200, Dakopatt, Denmark), L26 for B lymphocytes(1 : 200, Dakopatt, Denmark), OPD4 for helper T lymphocytes(l : 200, Dakopatt, Denmark) and alpha-1-antichymotrypsin for macrophages(l : 2000, Dakopatt, Denmark). The following results were obtained : 1. All the periapical lesions studied were infiltrated by T lymphocytes, plasma cells, B lymphocytes, and macrophages. T lymphocytes were more infiltrated than B lymphocytes, and B lymphocytes and macrophages were less infiltrated than T lymphocytes and plasma cells(P<0.05 : Oneway ANOVA test). 2. In untreated group and canal irrigated and enlarged group of all the periapical lesions, helper T lymphocytes were predominently infiltrated(P>0.05 : Oneway ANOVA test). 3. In canal filled groups of all lesions except periapical cyst, plasma cells were predominently infiltrated. But, in canal filled group of periapical cyst, helper T lymphocytes were the predominent cells(P>0.05 : Oneway ANOVA test). The above results shows that the immunologic responses play important role in pathogenesis of periapical lesions and the immunologic response involved undergoes certain changes after endodontic therapy.

The aim of this paper is to find which types of pop-up store positively influence consumers and to analyze the factors that affect brand attitude and behavioral intention across different fashion pop-up store formats. The data was collected from 217 respondents in their 20s and 30s and then subjected to descriptive statistical analysis, oneway ANOVA and regression analysis using SPSS Statistics. The results of the oneway ANOVA test indicated that the 'Pop-up store of alliance with different kinds of industries' is the most effective type for increasing brand preference and brand recognition amongst consumers. Some further insights can be made from the regression analysis results. There are differences between pop-up store formats in terms of the cognitive factors influencing brand attitude and behavioral intention. Moreover, there are differences between pop-up store formats in terms of brand attitude factors influencing behavioral intention. Through the results of this study, fashion companies can determine the best type of pop-up store to open depending on their aims. In conclusion, this study provides valuable insights to fashion marketers, helping them to determine the appropriate factors to consider when planning fashion pop-up stores.

This study examined the expenditure on time-saving services and related variables. The time-saving services are food away from home, delivery food, dry cleaning, clothing care, helper and total service. The specific objectives of this study were: (1) to investigate the differences in the expenditure on time saving services according to social economic and demographic variables. (2) to investigate the differences in the expenditure on time-saving services according to role-overload, home goal orientation and work goal orientation. (3) to investigate the independent influence of variables related to the expenditure on time-saving services. For this objectives survey was conducted using interview. The data used in this study included 160 women living in Seoul from employed professional housewives, employed non-professional housewives and non-employed housewives. Statistical analyses were conducted using frequencies, percentiles, mean, oneway ANOVA, DUNCAN-test and multiple regression. The major findings were: (1) Wife's education, wife's age, income, tenure, level of living and employment status were significantly related to the expenditure on time-saving services by using the one-way ANOVA. (2) Income, education, level of living, number of children, and employment status explained the variance of the expenditures on time-saving services about 20%-39% by using a multiple regression method.

The objectives of this study are : (1) to measure the level of economic stress perception in Korean farm households. (2) to identify the effects of related variables such as socio-demographic variables and economic stability. The data from 505 farm households' wives was analyzed using statistical methods such as frequency, correlation, oneway ANOVA, lease significant difference test, and stepwise multiple regression. The major findings are as follows : The mean value of economic stress perception on the 505 wives was 33.5 points out of a possible 100. Among 3 subsectors, income stress perception had highest score. Socio- demographic variables such as family size, type of farm household, financial manager, debt, credit . grant assistant, wife's age, and educational level of the wife had a significant difference on the economic stress perception of wives in the ANOVA analysis. So did the objective and subjective evaluation of economic stability. As a result of multiple regression analysis, economic stability, debt presence, and wife age were verified explaining 23% of the variance of economic stress perception. Therefore, it can be said that farm wives had relatively high economic stress perception in the case of low economic stability, getting into debt and low age.

본 연구는 대구시의 교통카드자료를 이용하여, 환승정류장의 특성을 분석하였다. 대구시의 교통카드자료는 서울시와 달리 승차 정류장의 내용을 포함하고 있지 않고, 하차 단말기도 설치되어 있지 않기 때문에 환승정류장을 파악하기가 어렵다. 따라서 교통카드자료와 대구시 BMS자료와의 Matching으로 환승통행에 대한 데이터를 구축하여 본 연구를 진행하였다. 환승량 모형은 도심으로부터의 거리와 노선수는 양의 계수를 나타낸 반면, 대기시간은 음의 계수가 나타나는 것으로 분석되었다. 본 분석에서는 Oneway ANOVA 분석을 통하여, 최적의 군집수를 정하였다. 군집1은 군집중심이 2.99로써, 대구시 중심에 위치한 형태이며 군집2는 군집중심이 6.73으로 군집3은 군집중심이 12.78로써, 대구시와 경산시의 경계를 포함하고 있는 형태를 나타내며 있는 것으로 나타났다.

The purpose of this study was to investigate (1) children's field dependence by age and sex, (2) children's interpersonal problem solving ability by age, sex, and contextual factors, (3) children's interpersonal problem solving ability by field dependence. The subjects were 120 five-, seven-, and nine-year-olds. Children's field-dependence was measured with the Children's Embedded Figures Test (CEFT). Children's interpersonal problem solving ability was measured with the Preschool Interpersonal Problem Solving Test (PIPS Test). Statistical methods adopted for data analysis were frequencies, percentiles, means, standard deviation, t-test, oneway ANOVA. $Scheff{\acute{e}}$ test and Pearson's correlations. Major findings were that (1) The older children were more field-independent than the younger ones (2) The older children suggested more problem solving methods and higher-level problem solving strategies than the younger ones. (3) Children suggested higher-level problem solving strategies in contexts involving familiar as opposed to unfamiliar participants and contexts involving children as opposed to adults. (4) 9-year-olds' field-independence was positively associated with interpersonal problem solving ability.
