This dissertation is a study of the costume of the Yi dynasty by means of an investigation of the Ka-rae-do-gam-Eui-gue Do(嘉禮都監儀軌圖: a collection of paintings of the royal wedding ceremonies and processions issued by the royal court) and the Jung-ri Eui-gue Do(整理儀軌圖: a collection of a series of paintings showing the whole process of the royal courtesies and ceremonies on the occasion of the king's visit to Hyun-yoong Won in Hwa-sung in 1975年). The Yi dynasty period is roughly divided into two parts. The first period extends from 1392, in which the reign of the dynasty started, to 1600, when Imjin Waeran(the Japanese Invasion of Korea) ended; the second period lasts from 1600 to the last day of the dynasty in 1910. Of the "Eui-gue Do"(儀軌圖: paintings of the royal ceremonies) which were made in the first period of the dynasty, there is no extant example, the reference to which is found only in records. However, the examples of the "Eui-gue Do" belonging to the second period remain abundant in number, together with the detailed accounts about them. The followings are the conclusions deduced from this study, which tries to illuminate the pictorial characteristics as well as the traits of costume manifested in the above-mentioned two groups of paintings. Most of the costume seen in the Ka-rae-do-gam Eui-gue and the Jung-ri Eui-gue were not clad in accordance with the wearer's individual desire or taste, but in strict conformity with the norm and sense of order in the society based on the Cosfucian political and ethical principles.

This study was conducted to compare the nutritional status, nutrient intakes, and chronic disease risks of Chinese elderly people. MNA (Mini Nutritional Assessment) developed for elderly people was used to determine their nutritional status. In this study, participants consisted of 148 urban residents aged 65 years and over residing in three cities in Shandong Province, China. Participants were 67 (45.3%) men and 81 (54.7%) women, and average age was 72.8 years. According to MNA score, 77.7% of participants were 'well nourished', 22.3% were 'at risk of malnutrition', and 2% were 'malnourished'. Nutritional status was divided into two groups by MNA score as 'well nourished' and 'malnourished', which was formed with the combination of 'at risk of malnutrition' and 'malnourished'. Compared with the well nourished group, the malnourished group was older, and physical status indicators such as weight, BMI (Body Mass Index), and calf circumference of the malnourished group were much smaller. The malnourished group had higher prevalence rates of heart disease and stomach disorders while the well nourished group had a higher rate of hypertension. There was no significant difference between the malnourished group and well nourished group in nutritional intake below Chinese DRIs (Dietary Reference Intakes) among elder males. A higher proportion of elder females showed insufficient intakes of energy, protein, vitamin A, vitamin E, and zinc in the malnourished group compared to the well nourished group. The INQ (Index of Nutrition Quality) of calcium, magnesium, zinc, iodine, and most vitamins was less than 1 in both the malnourished and well nourished groups.

The DTC of voltage source inverter-fed PMSMs is based on hysteresis controllers of torque and flux. It has several advantages, namely, elimination of the mandatory rotor position sensor, less computation time, and rapid torque response. In addition, the stator resistance is the only parameter, which should be known, and no reference frame transformation is required. The DTC theory has achieved great success in the control of induction motors. However, for the control of PMSM drives proposed a few years ago, there are many basic theoretical problems that must be clarified. This paper describes an investigation into the effect of the zero voltage space vectors in the DTC system and points out that if using it rationally, not only can the DTC of the PMSM drive be driven successfully, but torque and flux ripples are reduced and overall performance of the system is improved. The implementation of DTC in PMSM drives is described and the switching tables specific for an interior PMSM are derived. The conventional eight voltage-vector switching table, which is namely used in the DTC of induction motors does not seem to regulate the torque and stator flux in a PMSM well when the motor operates at low speed. Modelling and simulation studies have both revealed that a six voltage-vector switching table is more appropriate for PMSM drives at low speed. In addition, the sources of difficulties, namely, the error in the detection of the initial rotor position, the variation of stator resistance, and the offsets in measurements are analysed and discussed.

The purpose of this study is to analyze the interior color characteristics of elderly housing facilities in U. S. A. For this purpose, a field survey was conducted between July 23 and July 31, 2003, visiting 10 elderly housing facilities in Contra Costa County, California. A three step analysis of the facilities involved. First, floor, walls, ceilings, base boards and doors in common spaces were examined for the color scheme using the "Pantone for Fashion and Home Color Guide" for each room. Measured Pantone numbers were converted to RGB color using "Chooser 3.0 of Pantone, Inc." Finally, the conversions were recorded as Munsell numbers. The results are as follows: First, the colors chosen for American elderly housing are high value and low chromatic colors. In many facilities, analogue colors such as BG, B, BP and Y, YR R, RP are used. Second, the colors of ceiling and wall are mainly very bright and low chromatic colors. The colors of floor are undertaking an Important role by generating major atmosphere in the America elderly housing. Third, the colors used for elderly housing are found inter-related. For example, the main color in the lobby is also used from corridor to stair and used again from lounge to dinning room as a secondary color. Fourth, it is found that accent colors are used at the beginning and end of stair and corridor outskirts in consideration of physical condition of elderly people. Fifth, there is no difference in color selection between elderly housing with low and high rental value. Preferably, more versatile colors are being chosen for elderly housing with the low rental value.he low rental value.

In mathematics education, teaching-learning activity can be divided largely into the understanding the mathematical concepts, derivation of principles and laws, acquirement of the mathematical abilities. We utilize various media, teaching tools, audio-visual materials, manufacturing materials for understanding mathematical concepts. But sometimes we cannot define or explain correctly the concepts as well as the derivation of principles and laws by these materials. In order to solve the problem we can use the computer. In this paper, character and movement state of various quadratic function graph types can be used. Using the computers is more visible than other educational instruments like blackboards, O.H.Ps., etc. Then, students understand the mathematical concepts and the correct quadratic function graph correctly. Consquently more effective teaching-learning activity can be done. Usage of computers is the best method for improving the mathematical abilities because computers have functions of the immediate reaction, operation, reference and deduction. One of the important characters of mathematics is accuracy, so we use computers for improving mathematical abilities. This paper is about the program focused on the part of "the quadratic function graph", which exists in mathematical curriculum the middle school. When this program is used for students, it is expected the following educational effect. 1, Students will have positive thought by arousing interests of learning because this program is composed of pictures, animations with effectiveness of sound. 2. This program will cause students to form the mathematical concepts correctly. 3. By visualizing the process of drawing the quadratic function graph, students understand the quadratic function graph structually. 4. Through the feedback, the recognition ability of the trigonometric function can be improved. 5. It is possible to change the teacher-centered instruction into the student-centered instruction. For the purpose of increasing the efficiencies and qualities of mathmatics education, we have to seek the various learning-teaching methods. But considering that no computer can replace the teacher′s role, tearchers have to use the CIA program carefully.

In the Oriental Medicine field the great three reference books are Hwantienaekyung(黃帝內徑, HJNK), Sihnnongbonchokyung(神農本草經, BCK) and Shanghanlun(SHR). HJNK has been a theory book regarded as a bible of the Oriental Medicine, BCK, a herbal book with 365 species of red letters noticed from Bonchokyungjipjoo(本草經集註) and SHR, very important clinical book with concrete prescriptions for the therapy of patients. Though these books were written by Chinese people ca. 2000 years ago, yet they are no doubt very important and effective ones in these days. Unfortunately they are handed down to all transmitted books for a long times because original ones were destroyed by fire and another troubles. In this study we have tried to extract three common terminological words and common theories from the prescription law by theoretical principles(理法方藥, clinical therapeutic mechanism) acquired through the comparative analysis of these three books. They are qi(氣), cold or heat(寒熱) and yin & yang(陰陽), and their practical basic theories have been evidenced through exterior & interior of body(表裏) and deficiency or exessiveness(虛實) by the heat of Sun. Also we would have realized that Oriental Medicine should be analyzed through various scientific techniques and clinical experiences, and necessarily unified to yin & yang monism from qi theory of the Sun in all human's life cycle(生老病死).

The objectives of not-for-profit organizations including government supported research institutes are, by definition, to achieve socially desired nonfinancial goals. Current reporting focuses on providing information to meet the needs of users. This information may be provided in the annual research report, financial report, and other reports. An objective of current reporting is to provide users with information that will assist them in evaluating the performance(efficiency and effectiveness) of reporting entity. The evaluation of R&D project's performance requires information not only about the acquition and use of resources, but also about the outputs and outcomes of R&D activities, This study aims to recommend that R&D Service Efforts and Accomplish- mints(SEA) reporting is useful for performance evaluation in national R&D programmes. To achieve this aims, I attempt to develop the R&D SEA measures with reference to the Concepts Statement No. 2 of the Governmental Accounting Standards Board. R&D SEA measures consist of five categories : (1) input measures, (2) outcome measures, (3) output measures, (4) re1a1e efforts to accomplishments, (5) explanatory information.

A duplex PCR method was developed to detect a transformation vector pSPB130 used in the development of a genetically modified (GM) rose plant. To detect a GM rose plant, the anthocyanin synthase ($ANS$) was used as an endogenous reference gene of rose in PCR detection. The primer pair RHANS-KF/KR producing 107 bp amplicon was used to amplify the $ANS$ gene and no amplified product was observed in any of the 9 different plants used as a template. The primer pair GMRH-KF/KR was designed to amplify the junction sequence between 35S promoter and flavonoid 3',5'-hydroxylase ($F3^{\prime}5^{\prime}H$) gene in pSPB130. The detection limit of the duplex PCR method is approximately 0.5%. This result indicates that this duplex PCR method could be useful for monitoring unauthorized GM rose in Korea.

The aging process is multifactorial and results from the combined effects of inherited(genetic) and acquired factors including life style, food habits, physical activity, and diseases. That give rise to the various approaches in aging. We are trying to study biological changes with aging, In detail we are focused on gene and protein function accompanied by normal or abnormal aging process, especially our efforts are aimed at revealing the functional relationship of proteins in aging as a final product of gene. We expect that proteomic approach to the study of protein function involved in aging should give us variety of integrated data to understand biological changes of long lived lives, We have applied expression proteomics to rat liver bred in dietary restriction or in at libitum to elucidate the effects of food habit on aging. Expression proteomics shows us protein profile in a selected tissue or cells as a whole and gives us the information about protein expression level, posttranslational modification and degenerative modification of expressed proteins. Comparative analysis of young and old rat liver by two dimensional gels shows that gene expression of several proteins was down regulated in old rats and some protein expression level is increased with aging. Dietary restriction slows down these changes of gene expression and in some proteins there's no difference in protein expression level at same ages in comparison with rats bred in at libitum. About forty protein was identified by peptide mass fingerprint with MALDI-TOF and rest of the protein of interest is in the course of identification, Also we are trying to make mitochondrial and cytosolic proteom reference map. These suborganelle proteom map will gives us the information about low abundance proteins and cellular localization of proteins. Proteomics is a growing methodology to study biological system. High throughput qualitative and qualitative aspect of this approach will gives us large amount of integrated information and speed up our understanding about biological system

Many old books concerning agriculture in ancient Korea were published during Yi dynasty, giving information on the agriculture of old and recent times, Present work describes the introduction of tobacco to Korea by reviewing old domestic or foreign agricultural literatures dealing with names of tobacco. Historically, tobacco had been called as many names such as Namcho, Yeoncho, Au, Seocho, Oecho, Hocho, Dampa Ko, Namkyongcho and Dampacke, and known to be introduced to Korea during early part of Kwanghwekun rule (year of 1618) from Japan. However, tobacco introduction from Japan to Korea seemed not be true by 2 historical facts. One is that at old time Japan had imported Chinese and Korean culture, and many crops during Nara and Heyan dynasties. The other is that there is no evidence of Japanese introduction found in Japan nowadays. The most plausible theory on tobacco introduction is that soldiers under General Youjung of Myong dynasty had brought tobacco to Korea during ImJinWaeRan(1592-1598). The above statements can be verified by old stories about Korean local tobacco varieties, and by letters Kim Dae Hyun(1553-1602) and General Youjoung.
