This study has been analyzed to write an ideal training evaluation table after analyzing validity of content organization and assigning score of evaluating elements of clinical practice of Dept. of dental technology. 220 junior students who are studying dental technology in D university in Daegu were questioned to analyze the relationship of content organization and score of clinical practice evaluation table. The corrected material has been inspected by SAS V8 for Windows. The results are as following. 1. The validity of content organization of clinical practice evaluation table has a result which can be reliable over than 70% but the validity of score shows low reliance. c 2. The validity of content organization of detail elements of clinical practice evaluation shows that overuse of material and attentiveness(3.78) and responsibility (3.60) are high response but in score organization, the validity shows that safety measure(2.36) when controling machines, arrangement(2.98) after use and ability (2.98) of solving problems are very low. 3. In the elements without interpersonal relation, it shows that those are related to each other. its grading is p < 0.01 so it appears to be meaningful. 4. In result of analyzing the effect to 'studying amount' mark in clinical practice evaluation mark, it appears the element of attitude for job to affect it. And in result of analyzing the effect to 'training attitude' mark, it appears the element of 'controling machines' to affect it. For these results, to be a better evaluation tool, it should be modified by continuous research with arranging evaluation elements to be marked differently in between elements.

A simulation procedure which can represent time-dependent nuclear characteristics of TRIGA Mark-III reactor is developed. CITATION, a multi-group diffusion-depletion program, has been utilized as calculational tool. The group structure employed in this study consists of 7 groups: -3-fast and 4-thermal-which is conventionally utilized in TRIGA type reactor analysis. Three-dimensional nuclear characteristics are synthesized by combining results from two-dimensional plane calculation and two-dimensional cylinder calculation, since direct three-dimensional approach is not yet possible. An effort ia made to develope a method which can extract effective zone and group dependent bucklings by neutron diffusion theory rather than conventional zone and/or group independent Ducklings by neutron transport theory, since neutron leakage is quite high for small core such as research reactors. It is turned out that the method developed in this study gives satisfactory results. The calculation is performed under assumptions that all control rods are fully withdrawn, that no samples are inserted in the irradiation holes and that the core is located in the center of the reactor pool. Burnup-dependent variation of core excess reactivity, time dependent change of Xe-135 poisoning and reactivity worth of rotary specimen rack are calculated and compared with operation records. Neutron flux and power distribution as well as neutron spectrum in each irradiation .facility are presented.

This article presents clean core criticality calculations and control rod worth calculations for TRIGA (Training, Research, Isotope production-General Atomics) Mark II research reactor benchmark cores using Winfrith Improved Multi-group Scheme-D/4 (WIMS-D/4) and Program for Reactor In-core Analysis using Diffusion Equation (PRIDE) codes. Cores 133 and 134 were analyzed in 2-D (r, ${\theta}$) and 3-D (r, ${\theta}$, z), using WIMS-D/4 and PRIDE codes. Moreover, the influence of cross-section data was also studied using various libraries based on Evaluated Nuclear Data File (ENDF/B-VI.8 and VII.0), Joint Evaluated Fission and Fusion File (JEFF-3.1), Japanese Evaluated Nuclear Data Library (JENDL-3.2), and Joint Evaluated File (JEF-2.2) nuclear data. The simulation results showed that the multiplication factor calculated for all these data libraries is within 1% of the experimental results. The reactivity worth of the control rods of core 134 was also calculated with different homogenization approaches. A comparison was made with experimental and reported Monte Carlo results, and it was found that, using proper homogenization of absorber regions and surrounding fuel regions, the results obtained with PRIDE code are significantly improved.

Background and purpose: The purpose of this study is to review the recent achievements on ryodoraku and suggest new ryodoraku studies. Methods: The study papers related with ryodoraku, published in foreign countries and Korea up to the present, were collected first by internet search & journal. And then the collected papers were classified and summarized. Results and Conclusion: There are three study trends. One is finding some effect and analysis for some symptoms, another is finding a distinguishing mark and a diagnostic index, and the other is raising several points & providing solution & studying about relativity with another diagnosis. Some studies finding some effect and analysis for some symptoms are to be classified into four items(1. effect of drugs medication. 2. effect of ryodoraku therapy. 3. effect of other treatments. 4. effect of other treatments with ryodoraku therapy). Other studies finding a distinguishing mark and a diagnostic index are to be classified into two items(1. diagnostic index of symptoms. 2. distinguishing mark of disease). The other studies are to be classified into three items(1. ryodoraku introduction and raising several points at issue. 2. improvement machinery and tools. 3. studying about relativity with another diagnosis). Finally we need solving the ryodoraku problems(the condition of measurement and reproducibility, relation with Kyung-rak(經絡) and Ryodoraku, the reason of Ryodoraku points producing and etc.).

The EMFG (Extended Mark Flow Graph) is known as a graph model for representing the discrete event systems. In this paper, we introduce input/output matrixes representing the marking variance of input/output boxes when each transition fires in an EMFG, and compute an incidence matrix. We represent firing conditions of transitions to a firing condition matrix for computing a firable vector, and introduce the firing completion vector to decide completion of each transition’s firing. By using them, we improve an analysis algorithm of the EMFG’s operation to be represented all the process of EMFG’s operation mathematically. We apply the proposed algorithm to the system repeating the forward and reverse revolution, and then confirm that it is valid. The proposed algorithm is useful to analysis the variant discrete event systems.

This study was conducted to evaluate the nutritional status of the elderly women, who attended the Health Promotion Program of the Seogu Health Center in Daegu. The study subjects were 158 elderly women in an urban community. The general characteristics, dietary behavior (nutritional knowledge, nutritional attitudes and dietary habits), food and nutrient intake were surveyed by an individual interview. The average age of the study subjects was 70.9 $\pm$ 2.3 years of the subject group 79.1% ranged in age from 65 to 74 years and 20.9% were over 75 years. Their average score for nutritional knowledge, nutritional attitudes and dietary habits was 7.3 (total mark of 10), 7.2 (total mark of 10) and 9.1 (total mark of 22) respectively. Specifically, the level of the dietary habits of the study subjects was very low. In relation to food group intake of the study subjects according to age, their food intake was low. The total, plant. and animal food intake were 1078.9 g, 954.4 g (88.5%), and 244.4 g (11.5%), respectively. The mean daily energy intake and nutrient intake according to percentage of the Korean RDA were higher in the from 65 to 74 year group than in those people over 75 years. The average calories and the mean percentage of nutrient intake, except for vitamin C and phosphorus. were below 75% of the Korean RDA. It seems that the nutrient intake was very low. The mean nutrient adequacy ratio (MAR) was 0.59. Nutritional status of age over 75 years old was significantly lower than that of 6574 years old group (Mar ＝ 0.60 VS 0.54, p ＜ 0.05) The correlation coefficients between their dietary behavior (nutritional knowledge, nutritional attitudes, dietary habit) and their mean nutrient adequacy ratio (MAR) showed significant linear relations. In conclusion, if nutritional education is to affect the dietary behavior of elderly women, it should be included in a Program to Promote their nutrition and health status.

This study was designed to observe the degree of nutritional knowledge, eating habits and nutritional attitudes of elementary school teachers in Seoul. Two hundred seventy eight teachers were examined on questionnaire I October. 1994. The results of this study are summarized as follows. 1. 82.7% of the subjects were not experienced the nutrition education after graduated. They had information about nutrition through the newspaper and magazine and only 26.4% of the subjects reflected in their daily lives the nutrition information. 2. More than 65% of the subjects took a regular meal and above 90% of the subjects took korean food style as breakfast and dinner and 71.5% of the subjects ate mixed food such as barley or bean. 3. 693% of the subjects pointed out the problem of meal pattern such as overeating, too salty and hot, and irregular meal time. 4. The average score of their nutritional knowledge was 21.88(the highest mark was 30.00) and related to the sex, age, monthly total income, the length of career in school lunch program. 5. The average score of their eating habits was 8.65(the highest mark was 16.00) and related to the sex, the number of family, monthly total income, the length of career in school lunch program. 6. The average score of their attitude toward the nutrition was 26.83(the highest mark was 45.00) and related to the only age. 7. Nutritional knowledge had positive correlation with their eating habits and nutritional attitude. Eating habits had positive correlation with nutritional attitudes, too. In this study, the subjects was poor in nutritional knowledge, attitude and eating habits. It is necessary to develop the nutrition education program to make us recognize the importance of nutrition and health.
