This study is the research on the thermal emissivity depending on the bulk graphite's alignment degree. Bulk graphites were manufactured by uni-axial pressing and subsequent heat treatment of natural graphite flakes with organic binder. The samples were prepared to be $0^{\circ}$ (relative to the 002 c-face), $45^{\circ}$, and $90^{\circ}$ (relative to the 100 a-face) for measuring alignment degree. The alignment degree of the sample was measured by XRD. The thermal emissivity was measured by infrared thermal image camera at $100^{\circ}C$ and compared with the value obtained by Infrared spectroscopy. The alignment degree and thermal emissivity of $0^{\circ}$ sample were measured to be 0 and 0.70 respectively. And those of $90^{\circ}$ sample were 0.73 and 0.80 respectively. The emissivity value was correlated with obtained by IR spectroscopy. Therefore it was considered that the thermal emissivity of the bulk graphite is correlated with the alignment degree.

This descriptive correlational study was carried to identify the relationship among social support, compliance, and psychosocial adjustment of patients with rheumatoid arthritis. The study was done with 100 rheumatoid arthritic patients who were visited in Outpatient clinic of university hospital in Taegu, Korea from the 23rd of February to the 20th of March in 1998. The Data were collected through person to person interviews which were performed by five researchers. The instruments used for this study were Yu's social support scale(1996), Cho's compliance scale(1987), and Kim's psychosocial adjustment scale(1997). The data was analyzed by using a t-test, Pearson correlation coefficient, ANOVA, and Tukey test with the SAS Program. The results of this study were as follows ; 1. The mean score of social support was 2.76 for 4 full marks, compliance was 3.20 for 5 full marks, and psychosocial adjustment was 2.26 for 4 full marks. 2. Hypothesis 1 : "The higher the social support degree, the higher the compliance degree of the rheumatoid arthritis patient". It was supported(r=0.54, p<0.001). Hypothesis 2 : "The higher the compliance degree, the higher the psychosocial adjustment degree of the rheumatoid arthritis patient". It was supported(r=0.34, p<0.001). Hypothesis 3 : "The higher the social support degree, the higher the psychosocial adjustment degree of the rheumatoid arthritis patient". It was supported(r=0.24, p<0.05). 3. In general, the spouse group compared to other groups was demonstrated as the most dependable group for patients to trust and expect support. And the sons and daughters group was shown higher than other groups in terms of social support(F=4.19, p=0.01). There was no difference in terms of compliance in degree. In the degree of psychosocial adjustment the highly educated group(more than high school) is a little higher than the lowly educated group(F=3.08, p=0.03). In the costs of medical care, the group that could afford was significant higher than the group which could not afford results in terms of the psychosocial adjustment degree(F=3.99, p=0.01). The outcome of this study is that the social support that related rheumatoid arthritic patients had an effect on the following compliance, and the following compliance helps psychosocial adjustment of patients. It also shows that social support related psychosocial adjustment. Therefore, to increase the level of psychosocial adjustment of rheumatoid arthritic patients, it will be effective in supportive nursing intervention to improve social support and compliance.

Elementary schools students'degree of satisfaction on school food service and food preference were surveyed from 352 sixth-grade students in Kwangju and Chonnam area from June 22 to July 3 to enhance the quality of foodservice. The degree of satisfaction was high with cooked rice and soup in terms of temperature and serving state. There were significant differences in the degree of satisfaction depending upon the types of foodservice (p<0.001). There was significant differences in degree of satisfaction for side dishes depending upon the temperature (p<0.05), kinds (p<0.01) and amount (p<0.001). The degree of satisfaction with Kimchi was generally high in the serving state (p<0.05) and the amounts (p<0.01). The degree of satisfaction with desserts were high in the amount (p<0.001). The amount of leftover was high with soup, side dishes, kimchi, cooked rice, and desserts in order. The improvements made on children's behavior after the implementation of the school foodsevice were the adaptation to balanced diet and spending less money on sweets. The factors of influencing the school foodservice and the children's food intake were the education in school (teachers and dietitians) and the health status of their bodies (p<0.001). Children's favorite foods were sweet and sour pork, pork cutlets, oranges, watermelons, and strawberries in order. The least preferred foods were garlic seasoned with soy sauce, raw vegetables of broad bell-flowers, crown daisy greens, and steamed peppers. Children's favorite food types were fried food, desserts, one course meal, and bread. The least preferred types were pickled food, green and seasoned vegetables, cooked rice, and hard-boiled food in order. Generally, the children in the rural area favored most foods compared with those from urban area.

Let L be a linear functional on the vector space of polynomials in x. Let $\omega(x)$ be a polynomial in x of degree d, for some positive integer d. We consider two sets of polynomials, ${R_n (x)}_{n \geq 0}, {S_n(x)}_{n \geq 0}$, such that $R_n(x)$ is a polynomial in x of degree n and $S_n(x)$ is a polynomial in $\omega(x)$ of degree n. (So $S_n(x)$ is a polynomial in x of degree dn.)

Horizontal starch gel electrophoresis for 29 populations (n=543) of the wrinkled frog, Rana rugosa, from Korea and Japan was peformed to assess the degree of genic variation and genetic diversity, and to understand the biogeographic pattern of distribution and speciation. A sum of 22 presumptive loci was screened from 17 enzymes and general proteins. Four loci, Aco, Est-3, Me-2, and Pgm, demonstrated high levels of polymorphism. The degree of average genetic variation of R. rugosa was P=22.7% (9.1-40.9%), Ho=0.086 (0.048-0.165) and He=0.090 (0.042-0.168). In the south-eastern region of the Korean peninsula (Chongsong, Yongchon, Ulsan, Kyongju, Pohang, yongdok and Ulchin), a few unique alleles in the Mpi locus were detected and their biogeographic implications were considered. The degree of genetic differentiation among the Korean populations was moderate (S=0.900), whereas the degree of genetic diversity between Korean and Japanese populations was notably high (S=0.687, D=0.293). This result corresponds with the data obtained by the mitochondrial cytochrome b gene sequence (Lee et al., 1999) suggesting that the Korean and Japanese R. rugosa might have evolved a specific level of genetic differentiation since their geographic isolation.

Purpose: The purpose of this study is to investigate the understanding about speech therapy and the satisfaction of counseling about speech therapy according to the characteristics of mothers who have children with disabilities, and to devise the clinical instruction methods to provide the effective speech therapy by identifying the correlation between the two variables. Methods: This study conducted a survey for 78 mothers of children with disabilities who use speech therapy labs in university. 17 questions were composed to investigate the understanding degree about speech therapy and 24 questions were composed to investigate the satisfaction degree about speech therapy counseling. Results: First, the survey showed that mothers who have the higher education level have the higher understanding degree about language(p<0.01). Second, the survey showed that mothers who have the higher education level have the lower satisfaction degree about counseling process(p<0.5). In the view of job status, mothers who have a job have the higher satisfaction degree about counseling time(p<0.5). Third, the survey showed that in the view of mothers'understanding degree about speech therapy and satisfaction degree about counseling, mothers who have the higher understanding degree about language, speech therapy tools and speech therapy area have the higher satisfaction degree about counseling. Conclusions: This study showed the necessity to understand the subjects'needs exactly and communicate with mothers actively. In addition, the concrete and various methods should be devised in order to increase the understanding degree about speech therapy and increase the satisfaction degree of counseling about the clinical practice environment and language therapy process.
