The purpose of this study was to develop a "Family Play Therapy Program" using puppets to decrease attachment problems for families with children having attachment problems and to examine its effectiveness. The participants were an experimental group of 16 individuals(8 children with attachment problems whose ages ranged from 4 to 5 and 8 mothers) and a control group of 16 individuals (8 children with attachment problems whose ages ranged from 4 to 5 and 8 mothers). The experimental group was treated through the Family Play Therapy Program, which involved the use of puppets and was held for twelve sessions twice a week. The changes in the participants were measured in order to examine the effects of the program. The researcher measured children's emotional and behavioral expression(TBP), the mothers' sense of self(Self-Differentiation Scale), personal relationships(ECR-R), and the perception of family functions(ICPS-FFS) both before and after the FPT program and compared their differences. The MIM Rating Scale and Marschak Behavior Rating Scale were administered to examine the interactions between mothers and children, and 1:1 interviews were also conducted. The data thus gathered were used for non-parametric analysis(Mann-Whitney U test and Wilcoxon rank sum test)using SPSS WIN 17.0. The results of this study were as follows: First, the program had a positive effect on children's emotional expression. After the problem were over, negative emotional and behavioral expression in the experimental group decreased. Second, the program had a positive effect on mothers' self-differentiation and personal relationships. Third, the program had a positive effect on changes in the interaction behaviors between the mother and child. Fourth, the program had a partially positive effect on the responses from their group developmental stages, especially on the subscale of both a program for the reinforcement of mothers' emotions and family play program utilizing puppets.

This paper empirically investigates the finance-growth linkage in Korea by utilizing firm-level data of manufacturing industries before and after the 1997 financial crisis. We find that, first, an increase in external finance is associated with a faster subsequent capital accumulation of firms. However, this capital accumulation channel became relatively attenuated after the crisis. Second, the total factor productivity growth effect of external finance has been considerably weak both before and after the crisis. Third, the information production and industry restructuring effects of external finance have also remained weak after the crisis. The limited role of external finance in post-crisis Korea partially reflects sluggish corporate investment and weakening dependence of good credit firms on external finance. The evidence suggests that, in order to effectively sustain economic growth, further reform efforts may be required to strengthen resource allocation and corporate restructuring roles of financial markets and institutions.

In the period from the year 1500 to 1980. at least 14 large earthquake with epicenters in the northeastern China and Yellow Sea were felt or destructive in the Korean Peninsula. The most sigmificant events among them were the 1668 July 25 Tancheng earthquake of mamnitude 8.5, and the 1975 Feb. 4 Haicheng earthquake of magnitude 7.3. The Haicheng earthquake of the year 1975 in am extraordinary one among those occurred in the northeastern China in the 20th century in the sense the Shake of the event affected all over the Korean Peninsula. The tremor was felt even at the southeastern tip of the Korea and northern part of Kyushu 700km far away from the epicenter. In order to see the variation and trend of the effect of the Haicheng earthquake on the Korean Peninsula, the two data sets of the northern and southern parts of the peninsula were merged into one combined data set. The spatial variation of intensity shows smooth decrease from the value 4 of the northwestern region near the source to the value 1 of the Cheju Island and Kjushu. However, there are four regions of locally high intensity value. They are the region along downstream of Abrok(Yalu) River with intensity 5, the region around Shinpo of intensity 4, the area comprising Seoul and Chuncheon Cities of intensity 4, and Pohang-Pusan area of intensity 3. We suppose that there might be three types of possible mechanisms. The first one is concerned with the lateral inhomogeneity of velocity in the crust caused by wide distribution of relatively fractured rock. The second one is related with reflections of surface waves caused by the crestal thinning effect at border regions of the Peninsular in contact with the Ulleung Basin and the Japan Basin. The third possibility is local site effect caused by thick Tertiary or Quaternary rocks and soil layers.

This study aims to examine the influence of tennis instructors' coaching behaviors on the satisfaction with lessons and preference for instructors. In order to achieve this study objective, by using the quota sampling out of nonprobability sampling for tennis club members who are now(2015) actively involved in tennis courts located in Daejeon Metropolitan City and Chungcheongnam-do, and also receiving tennis lesson for more than six months or used to take lessons before, the 325 effective samples were used for data analysis. Using the SPSS Ver. 21.0 Window Program, the collected data went through frequency analysis, exploratory factor analysis, reliability analysis, t-test, one-way ANOVA, correlation analysis and multiple regression analysis, and the results are like below. Regarding differences of coaching behaviors depending on sex, first, there were significant differences in the factors like explanatory instruction, positive feedback and negative feedback. In case of differences in accordance with age, every factor showed significant differences. In regard of differences depending on academic background, there were differences in the factor of negative feedback while the factor of positive feedback showed differences in accordance with the experience of lesson. In case of differences depending on the level of athletic performance, there were statistically significant differences in the factors like explanatory instruction, questioning instruction and negative feedback. Second, the positive feedback, one of the sub-factors of coaching behaviors had positive influence on satisfaction with lesson while the explanatory instruction, one of the sub-factors of coaching behaviors had positive influence on preference for instructors. Lastly, the satisfaction with lesson had positive influence on preference for instructors.

Ketene-forming eliminations from C4H3(S)CH2C(O)O-C6H3-2-X-4-NO2 (1) promoted by R2NH in MeCN have been studied kinetically. The reactions are second-order and exhibit Bronsted β =0.51-0.62 and |βlg|= 0.47-0.53. Hence, an E2 mechanism is evident. The Bronsted β increased from 0.33 to 0.53 and |βlg| remained nearly the same by the change of the base-solvent from Bz(i-Pr)NH/Bz(i-Pr)NH2+ in 70 mol% MeCN(aq) to Bz(i-Pr)NH-MeCN, indicating a change to a more symmetrical transition state with similar extents of Cβ -H and Cα -OAr bond cleavage. When the β-aryl group was changed from thienyl to phenyl in MeCN, the β value increased from 0.53 to 0.73 and |βlg| decreased from 0.53 to 0.43. This indicates that the transition state became skewed toward more Cβ -H bond breaking with less Cα-OAr bond cleavage. Noteworthy is the greater double bond stabilizing ability of the thienyl group in the ketene-forming transition state.

It is necessary to determine reliability indexes of existing railway bridges prior to setting up a proper target reliability index that can be used to introduce a reliability based limit state design method to design practice. Reliability is evaluated for a six PSC-I girder railway bridge, which is one of many representative types of double-track railway bridges. The reliability assessment is carried out for an edge girder subjected to bending moment. In the assessment, the flexural resistance and the fixed-load effect were obtained using existing statistical values from previous research on the introduction of limit state design to road bridge design. On the other hand, the live-load effect was determined using statistical values obtained from field measurement for the Joong-ang corridor, on which heavy freight trains are frequently passing. The reliability assessment is performed by AFOSM(Advanced First Order Second Moment method) for the limit state equation, and a sensitivity analysis for the reliability is performed for each factor of the load and resistance effects.

Concrete contains numerous microcracks at initially poured. The growth and propagation of nicrockacsk are believed tc finally incur the faiure of concrete. These processings are understood as a damage. Damage IS represented as a second-order tensor and crack is treated as a con tinuum phenomenon. In this paper, damage is characterized through the effective stress concept together with the hypothesis of elastic energy equivalence, and damage evolution law and constitutive equation of a damage model are derived by using the Helmholtz frte eriergy and the dissipation potential by means of the thermodynamic principles. The constitutive equation of the model includes the effects of elasticity, anisotropic damage and plasticity of concrete. There are two effective tangent stiffness tensors in this model : one is for elastic-darnage and the other for plastic damage. For the verification of the model, finite element analysis was performed for the analysis of concrete subjec:t to uniaxial and biaxial loading and the results obtained were compared with test results.
