The study is to derive a typical probable rainfall intensity formula(TPRIF) by analyzing pre-issued probable rainfall intensity formulas (PPRIF) over principal rainfall observation stations, and to obtain the regional characteristics based on the rainfall patterns by evaluating probable rainfall amount. The conclusions are as follows. A TPRIF which integrates PPRIF with a single pattern is presented. In deriving probable rainfall intensity, the application of TPRIF was more excellent than that of PPRIF. The value of R24/Rl which is the dimensionless ratio for rainfall characteristics tends to be inversely proportionate to the regional coefficient n. By comparing these values, the whole country could be divided into about 5 regions. In these five regions, the short-duration rainfall intensity is dominant in inland areas but the long-duration rainfall intensity is dominant in East Sea areas.

The objective of this study is to find out a reason why prescriptions have different effects on each patient who has same symptoms or same abdominal examinations and further more to classify the formulas more efficiently. In applying 's prescriptions, it is known that conventional ways such as treatment in accordance with symptoms or abdominal examinations have many advantages and problems reversely. To make up for the problems, additional references like strength of constitutional resistance and location of disease, degree of income and outgo are designed. And the notion in Oriental Medicine embracing aspects mentioned above corresponds to triple energizer. Triple energizer's exuberance-debilitation is able to draw an inference from some factors like density of skin interstices, elasticity of abdomen, appetite, digestive power. According to Exuberance-Debilitation of Triple Energizer, can be divided into five steps: weak(弱)-moderately weak(中弱)-neither weak nor strong(中)-moderately strong(中强)-strong(强). prescriptions would be dealt with those 5 steps, and it would be highly effective and consequently side effects could be reduced. On the basis of this classification method upon formula group, the prescriptions of can be applied more accurately by setting a direction through strength of constitutional resistance and location of disease and combining with existing references like symptoms, palpation and abdominal examinations.

Objectives : Examined the editing system and the characteristics of "Clinical Formula Science of Korean Medicine" to establish a basis for compilation system of the common formula science textbook for colleges of Korean medicine nationwide. Methods : Comprehended the "Clinical Formula Science of Korean Medicine" published by professor Hyeongok(1911-1987) in 1985 and analyzed its configuration system. Results : "Clinical Formula Science of Korean Medicine" has made it possible to understand the formula systematically by establishing and classifying 24 kinds of treatment method [the three treatment methods of cold-dampness, dryness-heat and interior deficiency and its subdivision, 19 kinds of treatment method (stomach, phlegm, eum, yang, spirit, essence, ki, blood, blood stasis, exterior, interior, half-exterior half-interior, water, wind, cold, heat, dampness) combined with reducing and vomiting] and main formula. These can be considered as professor Hyeongok's own method of classification, which is distinctive from the existing formula science system. Also, it suggests that a Korean medicine doctor should not use a biased formula science that is limited to some schools but apply the formula widely and synthetically because it is believed to pursue perfection in cure if the main formulas related to a physical disorder, pregnancy and childbirth, invigorating and purging five viscera, and Four-Constitution Medicine are added. Conclusions : "Clinical Formula Science of Korean Medicine" is seen as a formula science book which is to be consulted when compiling a common formula science textbook for colleges of Korean medicine by forming a Korean formula science system that is distinctive from that of China.

The study aims to figure phenomena and changes that underachievers in mathematics show in the process of learning a function. It is necessary to remind basic concepts once again in advance at a time of teaching underachievers in mathematics to check what they have difficulties in learning for further teaching later on. Five participating students said that teachers' detailed explanation was more helpful, and they found it difficult to learn tables, graphs and formulas at first, but as time progressed, they naturally accepted them. In this regard, it is necessary to use various expressions and means to teach underachievers in mathematics.

This study did a comparative analysis on the patterns of several male bodice slopers, followed by evaluating the appearance through a virtual garment simulation, which used a three-dimensional virtual garment system. Through this process, this study attempted to comparatively analyze the suitability of the garment or each sloper according to body parts. The analysis of the drawing formulas of bodices slopers had the following results. With a standard chest size, all six slopers had a 1:4 ratio for a front and back chest size; 1:5 or 1:6 for a front and back breast size 1:5 or 1:4 for a neck base circumference; and 1:20 or 1:12 for the chest size. When comparing the anthropometric figures and the actual measurements of each body part for the bodice slopers, the actual measurements secured extra amounts in the drawing process. The evaluation results for appearance of the six men's bodice slopers showed that the slopers used by companies (E and F) had top scores followed by the slopers made for (C and D), while the sloper for education (A) received the lowest scores. Regarding the results of the variance analysis verifying the significant difference between the slopers, twenty-five items had significant differences with the exception of four items on the front side and one item on the backside.

The shear strength of unsaturated soils, a research hotspot in geotechnical engineering, has great guiding significance for geotechnical engineering design. Although kinds of calculation models for the shear strength of unsaturated soil have been put forward by predecessors, there is still need for new models to extensively consider the nonlinear variation of shear strength, particularly for the nonlinear effect of the net normal stress on the shear strength of unsaturated soil. Here, the shear strength of unsaturated soils is explored to study the nonlinear effects of net normal stress with the introduction of a general nonlinear Mohr-Coulomb (M-C) strength criterion, and the relationship between the matric suction (or suction stress) and degree of saturation (DOS) constructed by the soil-water characteristics curve (SWCC) of van Genuchten is also applied for unsaturated soil. Then, two calculation models (i.e., an envelope shell model and an effective stress model) are established for the shear strength of unsaturated soils under the nonlinear strength theory. In these two models, the curve of the shear strength of unsaturated soils versus the net normal stress exhibits a tendency to gently. Moreover, the proposed formulas have flexibility and convenience with five parameters (for the effective stress model) or six parameters (for the envelope shell model), which are from the M-C strength parameters of the saturated soil and fitting parameters of SWCC of van Genuchten. Thereafter, by comparison with the classical theory of the shear strength of unsaturated soils from some actual cases, the rationality and accuracy of the present models were verified.

This study aims to examine pre- and in-service mathematics teachers' reasoning and how they justify their reasoning. For this purpose, we developed a set of mathematical tasks that are based on mathematical contents for middle grade students and conducted the survey to pre- and in-service teachers in Korea. Twenty-five pre-service teachers and 8 in-service teachers participated in the survey. The findings from the data analysis suggested as follows: a) the pre- and in-service mathematics teachers seemed to be very dependent of the manipulation of algebraic expressions so that they attempt to justify only by means of procedures such as known algorithms, rules, facts, etc., rather than trying to find out a mathematical structure in the first instance, b) the proof that teachers produced did not satisfy the generality when they attempted to justify using by other ways than the algebraic manipulation, c) the teachers appeared to rely on using formulas for finding patters and justifying their reasoning, d) a considerable number of the teachers seemed to stay at level 2 in terms of the proof production level, and e) more than 3/4 of the participating teachers appeared to have difficulty in mathematical reasoning and proof production particularly when faced completely new mathematical tasks.

Objectives : This paper examines the medical treatise and treatment methods of Zhang Jiebin on the depressive pattern, for clinical application today. Methods : The Zazhengmo/Yuzheng chapter of the Jingyue Quanshu, related texts and annotations of the Huangdineijing, and related contents among the medical texts of the JinYuan masters were analyzed. Developmental process of the medical theories were compared and examined. Results : Zhang focused on the mechanism in which emotion affects Qi leading to a disease state, and categorized Yu[鬱, depressed state] into three: anger depression, contemplative depression and comprehensive depression. The concept of the Five Depressive Patterns and its treatment from the Huangdineijing·Suwen which was considered as excess pattern was expanded to include deficiency pattern based on comparison with annotations of Wangbing, Hwashou, and Wang Andao. Treatment methods centered on purging was also expanded to include tonifying to restore the damaged Jing Qi. The depressive patterns anger depression, contemplative depression and comprehensive depression were subdivided according to excess and deficiency, for which formulas such as Shenxiangsan, Shoupijian, Guipitang were suggested. As the depressive pattern is caused by emotions and thus the Heart, the Yiqingbianqi method that directly deals with emotions was suggested. Zhang adopted Zhu Zhenheng's opinion which expands the category of Yu, and in the perspective of excess/deficiency, it is most similar to that of Li Dongyuan. Conclusions : Before Zhang, the depressive pattern was discussed in terms of it being excess pattern. However, Zhang's discussion on depressive pattern based on anger depression, contemplative depression and comprehensive depression focuses on emotional stagnation while suggesting the possibility of deficient stagnation, expanding previous understanding. In terms of treatment, tonifying methods for deficiency pattern was added, while consideration of emotion itself became necessary in treatment.

To improve the functionality of black garlic drinks, black garlic extract (5%) and five herb extracts (1%) were mixed in 70:30 (v/v) ratios as BHF1, and BHF2 was prepared using a 3X concentration of BHF1. After the black garlic and herb formulas (BHFs) were administered over the course of five weeks in rats by interval running training, the lipid profiles and the antioxidant enzyme activities were tested. The total phenolic content of the BHFs were significantly higher in BHF2 than they were in BHF1, and their antioxidant activities were dependent upon the total phenolic content. No significant difference was found in the total serum protein levels among the rats in the Ex-con group by interval running training and the rats in the BHFs-fed groups. However, the albumin level was significantly higher in the Ex-BHF2 to Ex-con group. AST and ALT activities significantly decreased in the BHFs-fed groups compared to the Ex-con group. In terms of changes in the serum lipid profiles, no significant difference was found between the specimens that underwent interval running training and those that did not undergo interval running training. Triglyceride levels, total cholesterol, LDL-C, and HTR levels in the serum were significantly decreased in the Ex-BHF2 to Ex-con group. No significant difference was found in the total lipid levels in the livers of the BHFs-fed groups and the Ex-con group. The triglyceride levels and total cholesterol levels in the Ex-BHF2 group were significantly lower compared to another group. Hepatic catalase activity was significantly increased in the Ex-BHF2 group, but SOD and GSH-px activities were significantly increased as the concentration of the BHF. The antioxidant enzyme activities by supplementation of BHFs increased; thus, three intakes of BHF each day could improve antioxidant status against different types of oxidative stress.
