  • This study was carried out to Investigate the biochemical characteristics, antibiotic susceptibility, serogroups and pili producibility test of enterotoxigenic Escherichia coli(ETEC) isolated from piglets with diarrhea in Kangwon province from March to October 1996. 1. Sixty eight E coli strains were isolated from 72 piglets with diarrhea and the biochemical and cultural reaction were compared with the classification criteria of Edwards and Ewing. 2. The serogroups of 26 isolates were classified as 08 : K87 6(8.8%), O20 : K1O1 4(5.9%), O141 : K85 4(5.9%), 09 : K103 : P987 3(4.4%), O45 : K 2(2.9%) 0139 : K82 2(2.9%), O64 : $K^{-}$2(2.9%), O149 : K91 1(1.5%), O157 : K88ac 1(1.5%) and O115 : $K^{-}$1(1.5%), respectively. 3. In antibiotic susceptibility test, the isolates showed high susceptible to Ak, Eno, Na, Gm, Am and Km, whereas resistance to Tc, Sm and Cf. 4. Sixty one strains(89.7%) of 68 I coli Isolates were resistant to one or more drugs. The isolates resistant to 2 and 3 or more drugs were 60.3% and 19.1%, respectively. Amog the 16 multiple resistant patterns, Sm Tc(11.5% ), Cf Sm Tc(11.5% ), Cf Cp Sm Su Tc(9.8% ) and Cf Cp Sm Su Tc(8.2%) patterns were frequently observed. 5. MRHA of guinea pig erythrocytes was detected in 9 out of 26 OK serotype and 9 out of 42 unidentified serotypes. MRHA titers of serotypes showed from 16 to 32 in O141 : K85 and no titers in O139 : K82. 6. By the GM1 ganglioside ELISA, $\beta$-, $\alpha$-, and $\gamma$-hemolysin producing strains was detected as 36, 6, and 5 from heat labile enterotoxin(LT) of 47 ETEC, respectively. The distribution of LT toxin from 112 isolates was showed $\beta$- hemolysin, 2 isolates $\alpha$-hemolysin and 3 isolates $\gamma$-hemol-ysin from 26 OK serotypes.

  • This study was planned to provide basic information to help teachers guide lookism-prone students in their home and school life, and to guide them in the unit relating to clothing in school curriculums. To carry out this experiment questionnaires were administered to 481 students in their first and second year in middle and high schools in Gwangju city. The questionnaires are composed of 3 themes; 'general matters', 'attitudes about and recognition of appearance management' and 'school adaptation'. The collected data was analyzed with Component analysis(Varimax rotation) and Cronbach's ${\alpha}$, T-test, one-way ANOVA, Duncan-test, Pearson's correlation analysis and multiple regression analysis using the SPSS WIN 14.0(Kr). The results of this study were as follows; 1. The more they managed their behavior relating to appearance and cleanliness, the better they felt their friendships. 2. The less they concentrated management relating to appearance, the better they felt about their relationships with their teachers. 3. The less they concentrated management relating to appearance but the more they managed cleanliness the easier they adjusted to school rules. 4. The less they pursued a trendy appearance but the more they managed cleanliness, the better they studied.

  • The purpose of this study is to explore the fundamental nature and meanings of the experiences of university students with regard to their smartphone usage in order to prevent smartphone addiction and provide guidelines to develop effective interventions. Nine university students who were currently enrolled in an university located in a Korean province participated in this study. In-depth interviews were conducted from June of 2012 to July of 2012, and data were analyzed using Colaizzi's phenomenological qualitative method. As a results, five theme and 40 subthemes of experiences of problematic smartphone usage were identified. Those themes include 1) a desperate try to connect with others(exposing oneself without appropriate self-protection, seeking emotional comfort, hurt and mistrust); 2) excessive use of smartphone and loss of self-control(more smartphone usage over computer/over-immersion/excessive usage/habituation, loss of self-control); 3) psychological difficulties(excessive attachment and dependence, separation anxiety, clingingness, reduced patience) ; 4) threats to daily functioning (changes in priorities, regressed independent daily functioning, irregular daily patterns, health problems, interruptions from free messenger, academic difficulties); 5) potential for recovery(conflictual feelings and doubts over smartphone usage, importance of interpersonal(face-to-face) communications, willingness to cut down the use, hope for recovery). This study provided suggestions for the prevention effort against smartphone addiction.

  • This study was done to find out the effects that group art therapy would have on low rank cognitive functions and the self-esteem of the elderly with dementia. The study subjects were four elderly females with light dementia symptoms who scored lower than 19 points on the MMSE-K(Mini Mental State Examination-Korea) test. They were chosen from the ${\bigcirc}{\bigcirc}$ Senior Welfare Service Center located in Seoul. A total of 15 sessions of a group art therapy were given once a week for 60 minutes from January 15th to April 30th of 2008, the research tools employed were the MMSE-K and the Rosenberg Self-Esteem Scale on which a pre-test and a post-test were given. The results obtained are as follows. First, it was shown that group art therapy is effective to improve the cognitive functions of the elderly with dementia. According to the pre-tests and post -tests based on MMSE-K, the average score improved from 16.75 to 19.75, using Wilcoxon non-parameter statistics, verification resultant p-value which significant difference exhibited as .046, from the pre-tests and post-test, the average score improved in the subordinate areas of Orientation, Registration, Attention and Calculation, language function, understanding and judgment but there was no significant difference, memory recollection improved by a score of 0.70 according to the pre-test and post-test. using Wilcoxon non-parameter statistics, the verification resultant p-value which significant difference exhibited as .043. Second, it appeared with the fact that group art therapy effects the Self-Esteem of the elderly with dementia. From the verifications of a pre-test and post-test on Self-Esteem, the average score improved from 20.75 to 24.25, the effectiveness of the program was given proven by statistically considering the statistical resultant p-value of .048.
