The purpose of this study was to develop and standardize the Korean version of the Parent Mealtime Action Scale(K-PMAS). The parents of typically developing preschool and elementary school children (N=887) ranging in age from 1 to 11 years as well as parents of children with developmental disorders (N=116) completed the PMAS. A subset of the participants were retested for reliability and also completed the Children's Eating Behavior Inventory- Korean Version (K-CEBI), which was used for assessing validity. The confirmatory factor analysis revealed that the theoretically-based 8-factor structure of PMAS fit the data well. The PMAS scores suggested acceptable levels of internal consistency and test-retest reliability. Validity was also supported by significant correlations between the K-CEBI scores and the differences in K-PMAS scores between the parents of children with developmental disorders and those of typically developing children. The results of one-way ANOVA showed no significant differences in K-PMAS scores between the genders. However, there were significant differences across ages. The means and standard deviations of the PMAS scale scores are provided. Clinical and research implications as well as limitations are discussed.

Purpose: The purpose of this study was to develop an instrument to measure the parenting behavior of primary caregivers of children in early childhood. Methods: An instrument was developed according to Devellis's instrument development process. The participants in this study who completed the main survey were 370 mothers and grandmothers. The survey was conducted from June 1 to July 30, 2014, and collected data were analyzed using item analysis, half-split reliability and Cronbach's ${\alpha}$ coefficient, exploratory and confirmatory factor analysis, convergent validity. Results: The factor structure of the instrument showed the cumulative variance as 55.7% in the factor analysis. As a result of a confirmatory factor analysis, a four-factor structure was found to be appropriate, and the construct validity and convergent validity of the instrument were thereby confirmed. The finalized parenting behavior instrument consisted of 26 items and four independent factors: affectionate, laissez-faire, educational and impulsive. A five-point Likert scale was employed, and a higher score in a particular factor showed that most of the behaviors belonged to the factor. Conclusion: The instrument developed in this study was found to be reliable and valid, and can be used to develop parent-child relationship building.

This study developed the Place Attachment to Childhood Home Scale and evaluated its validity and reliability. Samples consisted of 418 college students of four universities. Data were collected by questionnaire based on retrospective questions about the childhood home. Factor analysis resulted in 5 dimensions of place attachment : affection, place identity, place rootedness, playfulness, and place dependence. Especially, playfulness was a unique finding. The result of confirmatory factor analysis supported the five-factor structure. There were also significant correlations among sub-factors. The reliability of the scale appeared high (Cronbach's ${\alpha}$ = .948). Criterion-related validity was confirmed by significant correlations of the present scale with Attachment Scale to Place (Hess, 1997) and the Inventory of Parent Attachment (Armsden & Greenberg, 1987).

This study was to develop Korean version of Parenting Stress Scale. Primary research was processed thru Abidin's PSI(Parenting Stress Index) scale. For the pilot primary study, distri-buted questionnaire to the mothers who have three to twelve age children and tried factor analysis with 382 data sheets. At the result, 29 items and 5 factors among the 47 items of child domain, 28 items and 5 factors among the items of parent domain were extracted. At the secondary pilot study survey, reanalyzed the 57 items extracted by primary pilot survey with the 392 data collected from three to six age children's parents. For the item discrimination analysis, calculated item-total correlation and deleted the items under r=.20. For the validity test, reviewed content validity and construct validity. For the verification of construct validity, tried factor analysis. At the result, in child domain area, the four factors, 'Reinforces Parent's, 'Accep-tability', 'Attention Distractiveness', 'Demandingness' and 24 items were extracted. Among the common variance of child domain, 'explained common variance' was 82.05%. In parent domain area, the five factors, 'Restriction of Role', 'Depression', 'Social Isolation', 'Parent Health', 'Spouse Relationship' and 24 items were extracted. Among the common variance of parent domain, 'explained common dominator' was 82.40%. For the verification of reliability, Cronbach's ${\alpha}$ coefficient was calculated and in child domain, .69, .70, .67, .66 were produced by each item, respectively and total reliability coefficient was ${\alpha}$=.81. Reliability coefficient of parent domain was .73, .70, .70, .55, .73 by each item, respectively and total reliability coefficient was ${\alpha}$=.83. This study was processed as a primary research to develop the Korean version of parent stress scale which is originally from U.S.A. version of PSI and apply it to proper Korean culture. Therefore, the necessity of continuous study was discussed with more localized items and factors.

Nebramycin is a complex of aminocyclitol compounds that is produced by aerobic culture in fermentation process. The major antibiotic factors produced by Streptoalloteichus hindustanus are nebramycin factor 2, 4, 5'and kanamycin A. A mutant was selected, producing nebramycin factor 5' activity 16.4 times higher than parent strain by microbiological assay using Pseudomonas aeruginosa CH-U34AF. The component ratio of nebramycin factor 5' was dramatically increased from 34% to 70% by the optimization of fermentation condition. It was found that the component ratio of nebramycin factor 5' in fermentation was especially affected by the oxygen transfer rate. Optimum oxygen transfer rate for maximal nebramycin factor 5' productivity and ratio during S. hindustanus fermentation was elucidated to $0.50 mMO_2$/min.

The purpose of this study was to develop the Family System Diagnosis Scale and to examine its reliability and validity. The subscales of the questionnaire included scores on seven constructs. In order to define constructs accurately, a careful review of Minuchin's writings, the writings of other family therapists, and relevant articles on family interaction was undertaken. A pool of 150 items was given to eight family counselors along with a description of Minuchin' s concepts. The counselors were asked to choose the category each statement fit and to rate the degree of fit using the 3-point scale. Using exploratory factor analysis, confirmatory factor analysis and Linear Structural Relationship(LISREL), six subdimensions of individuation and 55 items of FSDS were identified; enmeshmen disengagement(16 items), parent coalition generational coalition(6 items), flexibility rigidity(5 items), spouse conflict resolved unresolved(8 items), mother-child cohesion estrangement(10 items), father-child cohesion estrangement(10 items). 356 adolescents(ages 13∼18), 356 fathers, 356 mothers in Seoul, Busan, Dague, Incheun, Dajeun, Ulsan, and Kwangju were completed the Family System Diagnosis Scale(FSDS). The reliability of the scale was calculated by Cronbach's a Coefficient and the total a = .94 and the calculation for each factor was .87, .60, .77, .80 and .79 respectively.

The present study compared the self report and parental report on the behavior problems of adolescents as a way to explore similarities and differences in the ways that adolescents and their parents conceptualize behavior problems of adolescents. Specifically, K-CBCL and YSR data from 3271 adolescents between the ages of 12 and 17 were subjected to factor analyses. Five factors；Depression/Anxiety/Withdrawal, Aggressiveness, Somatic Symptom, Disruptiveness, Attention Getting were obtained from the YSR data with the first factor, Depression/Anxiety/Withdrawal explaining 14.23% of the total variance. K-CBCL data yielded somewhat different factor structure with Aggression/Delinquency as the first factor explaining 14.08% of the total variance, followed by Somatic Symptoms, Social Withdrawal, Disruptiveness, and Depression/Anxiety. Total K-CBCL and YSR score showed a moderate correlation(r=.51), and correlation between pairs of comparable K-CBCL and YSR factor scores were also moderate. Regression analyses of the variables contributing to the total problem score of the K-CBCL and YSR suggested that social competence and academic achievement are two important sources of influence on the evaluation of behavior problems both in self-report and parental report. However, externalizing problems such as aggressiveness/delinquency appeared to be more salient for parents, while adolescents themselves appeared to be more concerned with internalizing problems such as depression/anxiety. Implications of these subtle differences for assessment of adolescent behavior problems were discussed.

This research aims to identify relationships between stress level of parents in single parent families and life satisfaction in accordance with methods of getting rid of stress. Subject of the research were 260 parents in single parent families, centering on small towns in midsection sphere based on answers to questionnaire executed from March 1, 2013 to July 31, 2013. Collected data were analyzed by executing frequency analysis, factor analysis, t-test, one-way ANOVA, correlation analysis, regression analysis, etc. and an empirical verification was performed at 5% of significance level. From the result of the research, stress level appeared according to factors in a sequence of economic power, physical strength, social relation, family, mentality, etc. and significant influence to life satisfaction was found depending on factors such as stress removing methods and controlling effect. And minor factors were shown in a sequence of finance, emotion and acknowledgement. Suggestive points of the research are thought to be significance of stress removing method to the enhancement of life satisfaction, which will be a good material for the establishment of fundamental supporting plans and development of programs for single parent families.
