Nylon 6 ultramicrofiber(UMF, monodenier 0.074d) and regular staple fiber(monodenier 2.05d) were dyed with acid and disperse dyes to investigate the effect of the difference of the fiber fineness. Also X-ray diffraction pattern, birefringence, DSC thermogram, moisture regain and water absorption of these fibers are measured. The dyeing rate of nylon UMF with acid dyes is increased compared with that of regular fiber, but not increased for disperse dyes. Also the saturation dye uptake of UMF with acid dyes is higher than that of regular fiber, while it is unchanged for disperse dyes. The moisture regain of UMF is similar to the regular fiber, whereas the water absorption of UMF is two times th그n that of the regular fiber. The crystallinity percentage of UMF is higher than that of regular fiber.

Following the previous report (Part I: For Sea-divers and Hwa-Jeon-Min) authers have conducted another nutrition survey for Buddhists (male and female) in a temple 'Soo Duk Sa' locating in ChungNam province. The following results were obtained: 1. Cereals, green vegetables and potatoes were staple foods for the Buddhists (male and female) and no any animal foods were eaten by them during the survey period. 2. Carbohydrate intake was very high and the calorie derived from it occupied approximately 80% of tatal calorie intaken. 3. All the nutrients except carotene, niacin and iron are low in their amounts of intake. Especially, protein and riboflavin intakes are low. 4. Buddhists are prohibited to eat animal foods. Therefore, nutrition education and guidance are needed for them to supplement the protein and some other problems.

Rice, the staple food in Korea, is deficient to some extent in protein, lipid and vitamins. This study was carried out in order to investigate the effects of dietary supplementation to the rice diet of cellulose, ginseng, and ${\alpha}$-tocopherol on lead toxicity in rats. Using male rats fed the rice diet with the distilled drinking water containing 750mg of lead as nitrate per liter, for 11 weeks, organ weights, hemoglobin levels, serum glutamic pyruvic transaminase activity and accumulation of lead in liver, blood and kidney were observed. Supplementation of cellulose, ginseng and ${\alpha}$-tocopherol to the lead groups showed the protective effect significantly in the weight of liver but no influence in hemoglobin levels. Ginseng especially decreased the serum glutamic pyruvic transaminase activity to normal level. The three supplemented diets reduced the lead accumulation in kidney and blood, but not in liver.

Tideland reclamation in Korea has significant meanings both in securing the staple food supply and in enlarging the limited land resources. Environmentally, that significantly contributes in protecting the sea and the tidelands connected to a reclaimed area from the direct exposure to the environmental destruction by filtering the large volume of contaminant discharged from the inland. Furthermore, within few years after closing a sea dike. formulation of new tideland begins in wide area in front. Therefore, tideland reclamation should not be the one that must be unconditionally objected. Instead, the methodology should be wisely redirected to minimize the environmental disorder. It will be one viable alternative to proceed the tideland reclamation at medium- to small-scales environment-friendly bringing minimal environmental change in the sea.

To devise better development plan, survey was conducted about current Farmer's irrigation Practice on upland in the Youngsan River Irrigation Project District IV. Major upland crops are garlic and onion in this region. Currently, upland irrigation is conducted using ground water. It is found that irrigation interval is $2{\sim}3$ day for dry-field rice and $3{\sim}7$ days for other crop, in general. Whole day is required to irrigate for many farmers due to lack of facilities and water source. Farmers have no intention to change staple crops even after completion of Irrigation Project of Youngsan River District IV.

Cooked rice is a staple food for Koreans which provides more than 60% of daily required energy. In 1960's, Koreans ate 600 g-800 g of cooked rice per meal and the energy obtained from cooked rice was almost more than 80% of the daily intake of energy. However, as the economy of Korea improved, the major industry has been shifted from agriculture to various manufacturing industries and the export of those products has been increased thus increasing the national income but decreasing the farming population and thus rice consumption have been decreased. It has been said that the decreased rice consumption is caused solely by decreased farming population but it can also be said that the decreased farming population is caused by decreased rice consumption. As the national income increases, the type of foods people consume have become diversified. Various processed foods such as convenience food or ready-to-eat food have been widespread, which are mostly made of wheat flour rather than rice.

The purpose of this study is to improve the environmental applicability of nonwovens by using special composition. Polypropylene spunbonded and needle punched nonwovens which have the lower cost than polyester nonwovens were used as the raw materials to manufacture the natural fiber used nonwoven geotextiles. These geotextiles were made by use of the thermal bonding methods and composed of jute(or flax)/polypropylene staple fiber blends were obtained in consideration of environmental application. Finally, the engineering properties of natural fiber used nonwoven geotextiles were investigated as eco-friendly materials.

The present paper reports the impact of thermal treatment on the characteristics of core-sheath type hybrid technical yarns. The core-sheath type hybrid yams are prepared using DREF-III technology. Polyester and glass multifilaments are used as core components whereas the cotton and polyester staple fibers are the sheath components wrapped around the core filament with different proportions to form a hybrid structure. The thermal treatment is carried out both in dry and in wet state under relaxed condition and the thermal shrinkage, sheath-slipping resistance and tensile and bending properties of hybrid yarns have been studied. Thermal treatment markedly increases the thermal shrinkage and sheath-slipping resistance of hybrid yarns with polyester multifilament in core, but insignificant effect for yarns with glass multifilament in core. Breaking elongation of hybrid yams with polyester multifilament in core increases with treatment temperature. The hybrid yarns with glass multifilament in core are least affected by thermal treatment.

The purpose of this study was to investigate food habits and food preference of 108 male and 123 female college students through questionnaires. The results were summarized as follows ; 1. Average height of male and female students were 171.8cm, 160.2cm and the average body weight of those were 64.4kg, 51.4kg, respectively. 2.

Purpose: The purpose of this study was to identify and describe phenomenological structures of the experiences of dietary life on elderly over 100 years old. Methods: The participants of this research included nine persons over the age of 100 years of age and ten family members who assisted in the dietary regime. Qualitative data were collected by individual in-depth interviews. Data were analyzed using Colaizzi's method of phenomenology. Results: The results of the research provide four categories and nine theme clusters. The categories included a rustic menu consisting of vegetables, grain-oriented traditional food, sensible dining table in harmony with nature, dietary life and emphasis on how to eat. The nine theme clusters were preference for fresh vegetable, preference of cooked potherb, boiled rice and cereal as main staple food, intake of soybeans, preference of native local foods, non-preference of unhealthy foods, select healthy and control food portion sizes for longevity, objection to light eating, and enjoying a meal. Conclusion: The findings of the study offer insight about the nutrition patterns among the people over 100 years of age.
