  • The previous studies on the intake of trace elements performed in Korea were only concerned about major elements like Fe, Zn or Cu. There is little data about the intake of minor elements like Mn, Se, Mo or Cr. And most of the data were obtained by calculation using Food Composition Tables or by analysis using atomic absorption spectrophotometers (AAS). The purpose of this study, therefore, was to evaluate the dietary intake of seven trace elements, Fe, Zn, Cu, Mn, Se, Mo, and Cr of Korean adult wonmen and to compare the data between analyzed using ICP-MS (or ICP-AES) and calculated by the CAN-Pro (or Food Composition Table). A total of nineteen adult women participated voluntarily in this study and collected one-tenth of the foods that they consumed for three consecutive days. Analyzed intake of Fe of the subjects was $6.94{\pm}2.18$ (calculated, $18.87{\pm}4.50$) mg/day, that of Ze was $9.35{\pm}4.95$ (calculated, $8.35{\pm}2.87mg/day$), that of Cu was $1.18{\pm}0.26\;(1.11{\pm}0.32mg/day)$, that of Mn was $3.69{\pm}0.69\;(2.83{\pm}1.68mg/day)$, that of Se was $41.93{\pm}9.28$ (calculated, $27.58{\pm}6.97{\mu}g/day$), that of Mo was $134.0{\pm}49.1{\mu}g/day$, and that of Cr was $136.5{\pm}147.9{\mu}g/day$. The analyzed Fe intake of the subjects did not meet Estimated Average Requirement (EAR) nor Recommended Intakes (RI) for Korean women aged 20-29 years old. However, the analyzed intakes of the other six elements, Zn, Cu, Mn, Se, Mo, and Cr, seemed to meet each of the respective RIs. The analyzed Fe intake was significantly lower than the calculated one, in fact by 2.72 times, however, the analyzed intakes of the other elements, Mn and Se, were significantly higher and those of Zn and Cu were similar than each of the calculated ones. The difference of the data between analyzed and calculated intakes indicates that it is necessary to set up database on trace element contents of foods of the Food Composition Table and the CAN-Pro so as to have accuracy.

  • Objective : The recently reported Wuqian edition(吳遷本) Jinguiyaolue(金匱要略) is known to be written in small letters unlike other large lettered versions of the book. The Wuqian edition(吳遷本) takes after the name of Wuqian who copied an ancient version that was found at the time(Ming dyanasty, 1395). It is known to differ in organization and contents to other versions. In this study, I would like to examine how the small-lettered version of the Jinguiyaolue had been created, through a thorough examination of the Wuqian edition, and evaluate its value as a new version of the Jinguiyaolue. Method : First, the systems of both large-lettered and small-lettered versions of the "Jinguiyaolue" were briefly examined, followed by comparison from chapter 1 to 22, of organization, contents, and formulas between the oldest version of the large-lettered versions, the Deng-zhen edition, and the newly discovered Wuqian edition of which examples of each item are listed. The original source was identified for parts that were different. Result & Conclusion : 1. The Deng-zhen edition and Wuqian edition show vast differences in the organization, table of contents, name of chapter, location of each verse or line, existence of certain verses or lines, name of formula, quantity of medicinal ingredients, processing methods and other aspects. 2. The small-lettered edition was published based on the large-lettered edition of the Jinguiyaolue published by the Jiaozheng-yishuju(校正醫書局) after a general cross-examination process followed by selection, modification and supplementation of the large-lettered edition. Reference texts used in cross-examination were Qianjinyaofang(千金要方), Waitaimiyao(外臺秘要), Maijing(脈經), and Shanghanlun(傷寒論). 3. Considering Wuqian's own annotations and preface, it is clear that he wanted to create the best version of the "Jinguiyaolue". Wuqian himself seems to have had professional knowledge of bibliography and medicine.

  • The purpose of this study is to find out problems through looking into the actual condition of management and the extent of application in cooking practice in High School Home Economics Education, and as a practical subject, to present some basic materials to contribute to accomplishing the object of High School Home Economics Education through trying to find a direction to enhance educational value. The contents of this study are these : to study with a theoretical background character, object, and contents of Home Economics referring to related books and to investigate the actual condition of management, the extent of application to life of cooking practice unit, and standard of recognition of students and teachers about this subject and to find out rational and efficient method of management. 552 girl students and 72 home economics teachers in cities and counties in Kangwon-do were asked to answer the answer-sheet prepared. The result of this study is summerized as follows. 1. Most of the respondent regard the characters and objects of Home Economics as a matter of basic education, education for life, and education for the wholeman, but they neglect the aspect of education for a course of this subject. 2. Among the contents of Home Economics, students are much interested in the Unit of preparing table, especially in cooking. Most of the teachers teach the cooking unit with only explanation without practice because of the lack of material and human resources. 3. Students have desire to do cooking practice, but the extent of application of their real life appears to be low. 4. It appears to be necessary that boy students as well as girl students should learn Home Economics as an education for preparation for managing housework. 5. Home Economics teachers are mostly satisfied with their teaching profession. But teachers who have been teaching for 3 or 5 years appear not to be satisfied with it. 6. Although Home Economics teachers can teach Cooking practice Unit with confidence, they usually do it with theory rater than with practice, and they evaluate it after practicing, but most of them do not add the result to the student’s grade. 7. They use most of the cookers fixed on the standard list of High School Cooking Practice appliances, but they seldom use electric heating cookers.

  • The narration of "Donguibogam" is focused on humans whilst medical books before it focused on diseases. This is shown from the first subtitle of External Body(身形門) chapter, [The Origin of Hyung-Ki(形氣之始)]. The contents of [The Origin of Hyung-Ki] explains that the human body is composed of 'Hyung(形)' and 'Ki(氣)' This perspective is shown throughout "Donguibogam". First, in the aspect of construction, the viewpoint is shown from the JipRye(集例). It divides the body into inside and outside, which is a result of Hyung-Ki perspective. This continues in the table of contents. Naegyeongpyeon(內景) and Oehyeongpyeon(外形) describes the inside and outside of the body, in other words 'Hyung-Ki'. Japbyeongpyeon(雜病) describes complex illnesses with mixed insides and outsides. Tangaekpyeon(湯液) and Chimgupyeon(鍼灸) can be understood as division of treatment methods into inside and outside. When we look at the contents, the human body is created on the basis of the essence and vital energy of the world. Cheon-Ki becomes the 'Ki' that forms the functions of the body, while Ji-Ki becomes the 'Hyung' that constructs the bodily structure. It is considered that 'Hyung' is composed of SaDae(the body essence, vital energy, mentality and blood), and 'Ki' is composed of OSang(the five Jang organs and six Bu organs). 'Hyung' and 'Ki' show various appearances according to physiology and pathology. 'Hyung' is especially shown by obesity or thinness, 'Ki' by color. The obese may have Ki deficiency, coldness, dampness or phlegm. The thin could have blood deficiency, heat, fire or dryness. The color could show the pathology of the five Jang organs by the five colors, but it can simply be divided into black and white, where black means Eum deficiency, and white means Yang deficiency. It is said that the distinctive feature of traditional Korean medicine is that it is a constitutional medicine. In this perspective, further study on 'Hyung-Ki' is of value. If "Donguibogam" was the foundation of the Sasang Constitutional Medicine(四象醫學), study on 'Hyung-Ki' means searching for the origin of the Sasang Constitutional Medicine. Also, the study on Sasang Constitutional Medicine and Hyungsang medicine(形象醫學) will show the modern image of "Donguibogam". Hence, interchange study between "Donguibogam", Sasang Constitutional Medicine and Hyungsang medicine through the term 'Hyung-Ki' could hopefully lead to academic progression.

    • The long-term storability of home-made dry sausage and ham in terms of peroxide value and thiobarbituric acid value, the effects of nitrite and NaCl contents on the deterioration of the products and the public acceptance of dry ham were studied. The results of this study are as follows: 1. Because the storability of the dried meat products is mainly affected by the fat rancidity of the fat content, POV of 10 was assumed the critical point of storability. The sample dry sausage used in this experiment has lost its storability within a ripening period of 5 weeks. And dry ham was lost its peculiar relish within 50 days. 2. The variations of the NaCl contents of the dry products were reflected in the ripening process. The correlation coefficient between the variations of the NaCl contents and the decrease in the weight of the dry ham was 0.85. 3. The survey of public taste for dry ham was conducted on 35 college students, who think it a bit tasteful or tasteless account for 66% of the total and those who think it a simple relish account for 60%, thus indicating that the dry ham still remains far away from the dining table.

    • The total area of a reclaimed tidal soil distributed on the south-west coast is approximately 156,600 ha, and the soil contains high contents of sand and silt as well as highly saline. Most of the reclaimed tidal soils are used as a paddy due to bad permeability and high groundwater table, resulting in easy accumulation of salts on the soil surface by capillary rise. Therefore, resalinization may occur because of rise of groundwater table after desalinization. The researches related to the reclaimed tidal soil mainly focused on desalinazation while most of the researches completed were limited to yields of crop based on desalinazation. pH of old reclaimed tidal soil is neutral or less than 7 while that of newly developed reclaimed tidal soils is greater than 7, that cause N-fertilizer to be volatile as ammonia. Thus, the physical and chemical properties should be investigated to be used as an arable upland instead of a paddy soil due to change in government policy. We need to develop measures to make soils grow crops normally by identifying problems related to reclaimed tidal soils.

    • In this paper, we show that the instantaneous phase current of the bifiler-wound hybrid stepping motor is dependent of lead angle and that the information of motor position is obtained from the instantaneous phase current at ${\pi}/2$ by the theoretical formular and its computer simulation results. From the facts, we design the microcontroller-based motor position sensorless controller of optimal lead angle, which generates the excitation pulses for the closed-loop drives. The controller is consist of microcontroller which has the function of A/D converter, programmable input/output timer, and the transfer table which has the values of optimal lead angle depending on motor velocity, and ROM which has the transfer table of the values of lead angle depending on velocity of motor and the values of instantaneous phase current at ${\pi}/2$. From the design of microcontroller-based controller, we minimize the external interface circuit and obtain flexibility by changing the contents of ROM transfer tables and the control software. We confirm that the designed controller drives the bifilar-wound hybrid stepping motor is the mode of optimal lead angle by comparing the instananeous phase current experimental results and computer simulation results.

    • Phytoestrogen has been used as a suppliment of estrogen in order to treat osteoporosis. The representative phytoestrogens, isoflavones, are daidzein, genistein and formononetin which were present highly in our traditional soybean foods. The quantitative analysis of the isoflavone was done with a high performance liquid chromatography(HPLC) using a UV/VIS detector for the contents of the isoflavones in Astragali Radix, soybean sprouts, bean-curd(Tofu), soybean, soybean oil, pea, kidney pea, black bean(Yak-kong), soybean sauce(Ganjang). soybean paste(Doenjang), and fermented soybean(Maejoo). The content of free daidzein in soybean sprouts was $43.49{\pm}3.41\;mg/kg$$ which was much higher than that in soybean, $14.52{\pm}0.58\;mg/kg$, although total daidzein of fermented soybean was lower than that in soybean (Table 2. P<0.01). The amounts of free genistein in soybean sprouts, fermented soybean. and soybean paste were $27.63{\pm}1.66\;mg/kg,\;291.52{\pm}6.81\;mg/kg,\;and\;18.75{\pm}1.33\;mg/kg$, respectively. The level of free formononetin in soybean paste was the highest among the soybean products (P<0.01). The content of formononetin in Aatragali Radix, $9629.73{\pm}0.57\;{\mu}g/kg$, was about 160 times higher than that in soybean. Thus Korean traditional soybean products, black bean(Yak-Kong) and Astragali Radix can be a good choice of phytoestrogens.

    • The purpose of the study was to find out the rich sources of vitamin B-complexes in Korea. Thirty kinds of vitamin B-complex (thiamin, riboflavin, and niacin) rich foods were selected based on vitamin content in 100g edible portion, single serving size, 100kcal energy content, and 1999 national annual food supply data. The results were summarized as follows: \circled1 Most of the thiamin rich foods selected were fishes: half of the foods selected was fishes when based on the contents in single serving size. On the other hand, about half of the foods selected were vegetables when based on the thiamin contents in 100kcal energy content. A relatively large number of food groups were included such as fishes, vegetables, beans, grains, meats, etc. when based on the contents in 100g edible portion, and national food supply data. \circled2 Most of the riboflavin rich foods selected were fishes and shellfishes, and vegetables: half of the foods selected were fishes and shellfishes when based on the content in 100g edible portion; two-thirds of the foods selected were vegetables when based on the content in single serving size; half of the foods selected were vegetables when based on the content in 100kcal. \circled3 The most important niacin sources are fishes: Most than 60% of the foods selected were fishes when based o the 100g edible portion, single serving size, and 100kcal energy content. Laver is very important source of all 3 vitamin B-complexes in Korea when based on the content in 100g edible portion, 100kcal energy content, and national annual food supply but not in single serving size. On the other hand, rice is rice is sources of all 3 vitamin B-complexes when based on the national annual food supply, but not in single serving size. On the other hand, rice sources of all 3 vitamin B-complexes when based on the national annual food supply, but is not included in 30 rich foods selected based on the content in 100g edible portion, single serving size, and 100kcal energy content. Mushrooms are also very important food sources of thiamin, riboflavin, and niacin when based on the vitamin content in 100g edible portion, single serving size, and 100kcal energy content but not included in 10 rich food selected based on the national food supply data.
