본 연구는 장애아동 주 양육자의 행복감에 관련성이 있다고 규명된 요인들 간의 직접·간접효과를 분석하여, 장애아동 주 양육자의 행복감을 향상시키는 정책적인 대안을 탐색하는데 있다. 연구수행을 위해 전라북도 3개 지역을 대상으로 장애자녀의 주양육자 430명을 대상으로 수집된 자료를 활용하여 장애자녀 주 양육자의 사회적지지, 양육스트레스, 가족건강성과 행복감의 영향력에 대해서 살펴보았다. 주요 분석결과는 다음과 같다. 첫째, 사회적지지는 장애자녀주 양육자의 행복감에 직접적인 영향을 미침과 동시에 가족건강성을 통한 간접적인 영향력을 가지고 있는 것으로 나타났다. 둘째, 장애자녀 주 양육자의 가족건강성이 사회적 지지와 행복감 사이에서 매개효과가 있는 것으로 나타났다. 연구결과를 바탕으로 하여 장애자녀 주양육자에 대한 사회적지지, 가족건강성, 행복감을 증진하기 위한 사회복지적 융복합적 제언을 제시하였다.

A 2-year-old female Pekingese dog was presented with primary complaints including exercise intolerance and neurological sign associated with hepatic encephalopathy. The major findings in clinical examination included an intermittent seizure, a slow heart rate with pulse deficit, leukocytosis and anemia in hemogram, elevated pre- and post-prandial serum bile acid and hepatic enzymes, hypoproteinemia, coagulopathy, ammonium urate crystaluria and bilirubinuria. Diagnostic tests revealed an intrahepatic portosystemic shunt complicated with a second degree atrioventricular block and QT prolongation. The case was successfully treated with a transvenous coil embolization. Clinical signs were gradually improved and cardiac bradyarrhythmia disappeared. This case is a rare case of intrahepatic portosystemic shunts complicated with a cardiac bradyarrhythmia in a small breed dog fixed by a transvenous coil embolization.

Aboveground net productions of four stands in the coastal salt marsh of Incheon were estimated with three different methods: first method was to measure peak live standing crop; second to measure both live and dead standing crops; thrid to measure live and dead standing crops and dead disappearance as well. Net productions estimated by the first method were lowest with a difference of 28~50% from those by the third method. Whereas estimates by the second method approximated considerably to those by the third method with a difference of 4~15%. The third method figured out the highest values and seemed to be most appropriate in estimating net production of herbaceous community. Form these results it is known that live standing crop, dead standing crop and dead disappearance respectively accounted for about 60, 30, 10% of net production estimated by the third method. Annual net productions estimated by the third method for Suaeda japonica-Salicornia herbacea, Artemisia scoparia-Limonium tetragonum, Calamagrostis epigeios, and Sonchus brachyotus-Setaria viridis stand were 650, 1, 080, 1, 409 and 1, 126 g.$m^{-2}.yr^{-1}$, respectively.

This research is an experiment to examine on the realization of Natural Color using R, G, B LEDs and this experiment was performed to cover two different stages. 1) When Natural Color using R, G, B LEDs was realized without correction in first stage, all color(R, G, B, C, M, Y) series had highly range of error from 0.0200 to 0.1500. 2) When R, G, B of LEDs was mixed at the ratio of 1:4.5907:0.0601 for realization of white in second stage, white was not realized to excitation purity. The second stage was Performed based on the three primary colors theory found out by Thomas Young in England and Hermann Ludwig Ferdinand von Helmholtz in Germany.

This study is intended to investigate the effect on the development of multiplicative thinking and multiplicative ability by teaching repeated addition, rate, comparison, area-array, and combination problems. Two research questions are established: first, is there any difference of multiplicative thinking between the experimental group(the modeling of problem situation learning group) and the control group(the traditional learning group)\ulcorner Second, is there any difference of multiplicative ability between the experimental group and the control group\ulcorner The treatment process for the experimental group is based on modeling problem situations for nine lesson periods. In order to answer the research questions the chi-square analysis was used for the first research question and the t-test was used for the second one. The findings are summarized as follows: there is no significant difference of multiplicative thinking be1ween the experimental and the control group but there is significant difference of multiplicative ability.

A theoretical analysis of an annular injection supersonic ejector equipped with a second-throat was developed under the assumption that the secondary flow is choked aerodynamically by interaction with primary flow in the mixing chamber. The predicted secondary flow pressure agrees reasonably well with the measurements. Using the analysis, the compression ratio, the secondary flow Mach number, and the location of the choking point were presented in terms of entrainment ratio.

The purpose of this paper IS to investigate the aspects of errors of English stress by Korean students. In this experimental study, 17 students participated and read 120 words which are divided into three types-the beginning, the middle, and the advanced-according to the level of words. As a result of acoustical judgement, there were a greater number of errors In the advanced level of words, and the more syllables the words have, the more errors occurred, tins means Korean students who learn English as a second language have trouble realizing the right stress in words with larger numbers of syllables and the more advanced level. Furthermore it is interesting that Korean students imposed the primary stress on the second syllable when producing words with stress in the first, third and forth syllables.

Salivary gland tumors usually appear in solitary mass in single salivary gland. The coexistence of tumors with different histological types occurring within a unilateral parotid gland is an extremely rare event. We experienced a case which two different types of malignant tumors developed at different time points in same gland; metachronous tumors. The second tumor was excised widely and reconstruction was performed by free tissue transfer. Sensory and motor nerve to the left cheek appeared to be intact, and circulation was adequate. This rare case was presented in this article.

The purpose of this study is to analyze the fashion images and the aesthetic characteristics of hand work imaged design. The 'hand work' has not only affected the contemporary life style but also the current fashion trend. The primary source of data has been a collection of recent books, news repots, and many articles from various kinds of mass media and fashion magazines since the year 2000. The results of this study can be summarized as follow. First, hand work imaged fashion design can be divided the background into three parts : post-materialism, aesthetics of slowness, personalize trend. Second, hand work imaged fashion design can be identified with the following images : folklore & craft image, second hand image, high touch image. Third, the aesthetic characteristics of hand work image reflects the concepts of sustainability and process communication.

The purpose of this study is to investigate the level of the proporation of household expenditure item and the subjective burden of household due to the private educational expenses. The data used in this study included 761 housewives who have a child of the second grade or fourth grade of primary-school in Seoul. The findings of this study are as follows: First these six variables-educational level of mother household income place of residence grade of child number of child and the expected educational level of child-have significant effects on the private educational expenses. Second the proporation of food expense housing expense clothing expense and miscellaneous expense significantly differ with respect to the private educational expenses. Generally the proporation of household expenditure item and subjective burden are influenced more by the private educational expenses for school work than by the private educational expenses for talent.
