This report is a series of the investigation of the secondary vegetation and succession at the forest fire area in Dangji-Dong of Kyungsang-pookdo province. The forest fires occurred on April 8, 1982. This investigation was carried out from June 18, 1982 to May 29, 1983 once in each season. Before to fires, the Pinus densiflora was dominant and the woody plants of understory were mainly composed of the Quercus serrata, Q. dentata, Lespedeza maritima and L. macimowiczii. Compared with the florstic composition between the unburned and burned areas after the fires, the floristic composition of unburned area comprises: 79 families, 194 genera, 223 species, 26 varieties and 6 formae (255 kinds of vascular plants). The index of similary shows 0.77 (S$\Phi$renson:1948) in this area. The analyses of the life-form compositions in the unburned and burned area show 32.9% and 29.3% in dormancy form (H), 42.4% and 37.7% in disseminule form($D_1$), 80.8% and 82.2% in radicoid form ($R_5$), and 57.7% and 61.8% in erect form(e) respectively. The biological type shows H-$D_1$-R5-e, which is common in both areas, and erect form is generally prevailing in these communities.

Superconducting current lead is one of the promising applications of the oxide high-Tc superconductors, because they have the advantage of decreasing heat conduction to low temperature region, comparing with a conventional cooper alloy lead. High critical current density is a key factor for the applications such as current lead. $(Bi,Pb)_{2}Sr_{2}Ca_{2}Cu_{3}O_{x}$ high Tc superconductor hase been investigated in terms of critical current density. Bi-2223 superconducting current lead made by CIP and solid state sintering process. Bi-2223 current lead that heat treated at $836\;^{\circ}C$ for 240 h in 1/13 $PO_2$ had over $500\;A/cm^2$ of critical current density at 77K. We knew that the superconducting properties of tube type current leads were better than rods type of them. And we investigated the relation of Bi-2223 formation and heat treatment condition by XRD and SEM analysis.

Purpose: The purpose of this study was to investigate the stress level, coping behaviors and health problems of elementary school children and to compare the level of these three variables according to size of city of residence and to identify the relationship among the three variables. Method: Data were collected by questionnaire from 465 5th and 6th grade elementary school children living in Daegu and North Kyungsang Province. Data were collected between December 1 and 20, 2003 and analyzed using the SPSS program with means, standard deviation, t-test, and Pearson's correlation coefficients. Results: The stress level was significantly higher in children who lived in the big city. The coping behavior score was not significantly different according to size of city, nor was there a difference in the health problems according to size of city. There was a positive correlation among stress level, coping behaviors and health problems. Conclusion: In general, the stress level was significantly different but coping behavior scores and health problem scores were not significantly different according to size of city. Also the elementary school children used more passive coping behavior than active coping behavior. Therefore, strategies to develop active coping behaviors for these children are needed.

The aim of the present study is to investigate the complex shopping behavior of clothing consumer groups classified by the level of economic shopping orientation. Using a self-administered questionnaire, 260 respondents rated their economic shopping orientation, hedonic shopping orientation, convenient shopping orientation, store selection criteria, clothing interest, gender, age, and other demographic characteristics. A total of 248 questionnaires were analyzed. The results are as follows. First, economic consumers showed more hedonic and convenient shopping orientation than uneconomic consumers. In addition, economic consumers valued various store selection criteria. These implied that economic consumers show more complex clothing shopping behavior than uneconomic consumers. Second, as the result of comparing complex shopping behavior of economic consumers and uneconomic consumers by their characteristics such as clothing interest, gender, and age, economic consumers were found to show more complex shopping behavior than uneconomic consumers regardless of the consumer characteristics. Among them, economic consumers with higher clothing interest or in adult age particularly showed more complex shopping behavior. Furthermore, economic consumers with different consumer characteristics showed quite different aspects in their complex shopping behavior. Third, uneconomic consumers showed relatively simple, impulsive, and price-apathetic shopping behavior.

This study investigated the National Competency Standards (NCS) of fashion planning to compare the fashion planning curriculum of domestic universities and colleges with NCS as well as suggest ways to activate the application of NCS to fashion planning education. Qualitative research was employed based on references from the old and new homepages of NCS as well as fashion planning related subjects of domestic universities and colleges. The results are as follow. First, fashion planning NCS was composed of 10 competency units. Competency units were composed of competency unit elements and performance criteria. The levels of the competency units and the competency unit elements were suggested based on 8 stages. There were significant differences in the content of competency units and the level of competency units between the old version and the revised version of fashion planning NCS. Second, considerable fashion planning related subjects seemed at a higher level than the function level of recent college graduates. There were also omitted subjects which were required for recent college graduates. Third, the requirements for the reorganization of curriculums and education systems as well as the cooperation among industry, colleges, universities, and development part of NCS were suggested for the activation of NCS based education and the validation of NCS.

Objectives : The aim of this meta-analysis was to draw overall conclusions on the correlation between the organizational effectiveness (OE) of healthcare employees and related factors by summarizing recent studies and to provide a baseline for future research. Methods : A literature search for original articles published from 2005 to 2014 including doctoral theses and KCI journal articles was done in KERIS' RISS, etc. in a systematic manner. From 77 studies which met the inclusion criteria 190 effect sizes (ESs) were calculated for the analysis. A meta-analysis was done with CMA 3 (Biostat company, USA). Results : The overall ES was moderate for all, positively and negatively related factors. For all related factors, job characteristics, group-leader relations, personal and organizational characteristics had a moderate ES. The ES for work experiences was small. Conclusions : Although the results of this study were meaningful it is necessary to perform follow-up analyses (1) based on a longer data period and more articles, (2) including moderating variables with higher explanatory power and (3) adopting a study model with more specific and simplified variables.

Euiseong sub-basin, one of three sub-basins in Kyungsang basin, consists of various sedimentary and igneous rocks of Cretaceous age. Kusandong tuff and Yucheon volcanic rocks from the sub-basin were collected for the anisotropy of magnetic susceptibility (AMS) study. Maximum directions of the AMS for Kusandong tuff and Yucheon volcanic rocks are used to detect possible source areas. Although the dispersion of the maximum directions of the AMS, mainly due to low susceptibility and/or low percent anisotropy of individual specimens, is rather large, it is possible to reveal several source areas for the volcanic rocks. Areas near the Keumseongsan and Hwasan, calderas in the study area, are identified as source areas for Yucheon volcanic rocks, while the western part of Sunamsan, another collapsed caldera in Euiseong sub-basin, is inferred to be the source area for Kusandong tuff. However, it is not possible to determine detailed source areas for groups of Yucheon volcanic rocks of different lithologies, because of poor degree of convergence of the maximum directions of the AMS results from the volcanic rocks. It is also concluded that several episodic volcanic activities centered at Keumseongsan and Hwasan calderas were responsible for the formation of Yucheon volcanic rocks in Euseong area.

In this paper, we developed an omni-directional surveillance and motion detection method. The fish-eye lens provides a wide field of view image. Using this image, the equi-distance model for the fish-eye lens is applied to get the perspective and panorama images. Generally, we must consider the trade-off between resolution and field of view of an image from a camera. To enhance the resolution of the result images, some kind of interpolation methods are applied. Also the moving edge method is used to detect moving objects for the object tracking.
