The sacrificial foods using at 88 villages in Andong area where the village sacrificial rituals are performed, were investigated in 1994. The finding are as follows; 1. Since the village sacrificial rituals keep ancientry, white Baeksulki without any ingredients is used as Ddock (a steamed rice cake) in 74 villages, and in 5 villages the Baeksulki was served just in Siru (a tool used to prepare Ddock). The type of meat serving in rituals has been changing from large animal to small animal and the type of light from bowl-light to candle. 2. Though the ritual observes Confucianism style, memorial address was offered in 34 villages and only in 8 villages, liquor was served 3 times and the address was offered. In 60 villages, liquor was served only once, and calling village god, bowing twice, and burning memorial address paper were performed in order. Burning paper has been meaningful in rituals. 3. Tang (a stew) was served in 21 villages, and in 18 villages even Gook (a soup) was not used. The numbers of village which do not use cooked rice and Ddock are 14, respectively. 4. Fruits are essential in rituals foods. In 63 villages, 3 kinds of fruits are served and this is contrasted with even number of fruits in Bul-Chun-Wi Rituals. 5. In 25 villages, fish and meat are not served. As meat, chicken in 19 village are served. Meat Sikhae (a fermented rice beverage) prepared with meats or fish are served in 5 villages. Slice of dried meat is served in 73 villages commonly. 6. In gender of god for village shrine, woman in 43 villages, couple in 17 villages, man in 9 villages, mountain god in 2 villages, villages tree, etc were enshrined. In 52 villages liquor is served in rituals (liquor is used in 58 villages including serving god), in 28 villages sweet liquor (Gamju) is served for god (sweet liquor is used in 46 villages), and liquor, water, or sweet liquor is just displayed on table but not served in 8 villages. Incensing is found to be not common in village ritual, only in two villages it is performed. The most appropriate rituals food is thought to be pig for mountain god. Home dishes can not be used in village ritual and spoon is not used and chopstick is prepared from wild plant. Meat and fish are used in the raw.

This research was carried out to investigate relationship between underground part environment control and growth or yield of sweet pepper in greenhouse as affected by covering materials. Daily amount of applied nutrient solution for research period in the greenhouse of plasticfilm house was more 1.6 times than that in glass house. But daily absorptance rate of nutrient solution and specific electrical conductance of rockwool between two greenhouses were not different in the range of 71.3-73.3% and $4.17{\sim}4.23dS{\cdot}m^{-1}$ respectively. Leaf area of sweet pepper, in leaf growth characteristics in two greenhouses, were $123.0cm^2$/leaf (in glass house) and $119.5cm^2$/leaf (in plasticfilm house), but the another (fresh and dry weight, dry matter) were not different. But weekly yield per square meter in glass house was more 1.3 times than that in plasticfilm house as $850g{\cdot}m^{-2}$ and $650g{\cdot}m^{-2}$, respectively. Effect of slab EC and absorptance rate of nutrient solution on leaf growth characteristics and yield between two greenhouses were not different. The results show when sweet pepper is cultured in greenhouse as affected by covering materials and above ground part environment, the plant growth and yield are little affected by underground part environment.

With pot-grown 4-year-old 'Fuyu' persimmon trees, this study evaluated the effect of different nitrogen (N) rates during summer on fruit characteristics, changes of leaf nutrients after harvest, reserve accumulation, and early growth the following year. A total of 0, 36 g N in June, and 72 g N in June and July was fertigated to each tree using urea solution. All the fruits were harvested on Nov. 3. Although not significant, fruits were larger for the 36 g and 72 g N than the 0 g N. Fruits for the 0 g N, having lower N concentration, were softer and had a better coloration and higher soluble solids, indicating that they matured earlier. SPAD value on Nov. 3 was 19.2 for the 0 g N and 54.9 for the 72 g N, and then the values linearly decreased in all the treatments by Nov. 14, exhibiting rapid leaf senescence. Specific leaf weight, being the lowest for the 0 g N, also gradually decreased during this period. Increasing N level significantly increased cross-sectional area of the trunk. Leaf N concentration on Nov. 3 was 0.87% for the 0 g N, whereas it was 1.18 and 1.52% for the 36 g and 72 g N, respectively. The N fertigation tended to increase leaf concentrations of soluble sugars, starch, and amino acids. Contents of N, P, K, soluble sugars, starch, and amino acids per unit leaf area gradually decreased in all the treatments during the 11 days after harvest, and the extent of the decrease was the lowest for the 0 g N. On the other hand, those of Ca, Mg, and protein did not consistently change during this period. The N fertigation resulted in higher concentrations of N in dormant shoots on Nov. 14, and although not great, it also increased soluble sugars, starch, amino acids, and protein. Clear differences were found in number of flower buds per one-year-old branch and total shoot length per tree the following year. The 72 g N trees had 5.6-fold more flower buds and 1.9-fold more shoot length, compared with those of 0 g N trees. However, it was noted that tree growth the following year was not significantly different between the 36 g and 72 g N the previous year. It was concluded that N rate during summer should be adjusted with considering the changes of fruit maturation, mobilization of leaf nutrients, and reserve accumulation.

This survey was performed to investigate the distribution of specialities which cultivated importantly in Jeollabukdo area in order to understand food culture of this area. Foods in speciality were divided into 4 groups, agricultural, aquatic, animal and the others products. Total number of 93 species of specialities, including 40 species of agricultural products, 29 species of aquatic products, 8 species of animal products and 16 species of the miscellaneous products, were identified from Jeollabukdo area. Especially, there were various fruits and vegetables among agricultural products and fishes among aquatic products in this region. Rice, pepper, pear, Mandarin fish, beef, pine mushroom, lentinus edodes and honey were determined as specialities in Jeollabukdo area. Various aquatic products were specialities in Gochang, Gunsan, Buan and Gimje region. Fruits, mushrooms, wild edible greens and animal products were specialities in Muju, Jangsu, Jeongeup and Jinan. Sweet fish, cat fish and freshwater crab were caught off in Sumjin river region only such as Namwon, Sunchang and Imsil, Recently, pumpkin(Cucurbita maxima) and paprika were determined as specialities in Jeollabukdo. In case of aquatic products, mushrooms and wild edible greens, their wild type products decreased, while cultivated type increased Commercialization by brand naming of agricultural and animal products were rapidly increasing. The kinds of specialities in Jeollabukdo area were changing by the influence of geographical, religious and social factors.

A study was carried out to investigate the threshold values of four taste qualities by using electrogustometer for Korean female college students. The mean values of taste threshold before the treatments were for $7.5{\mu}A$, sweet taste area, $19.6{\mu}A$, salty taste area, $23.5{\mu}A$, sour taste area, $18.4{\mu}A$, bitter taste area and $50.7{\mu}A$, middle area, respectively. The thresholds of taste for the each area of tongue of the after-treatments were more sensitive than those of the before-treatments except the after-treatment with sodium chloride in which the sensitivity was much reduced. There were no significant differences between the thresholds of left and right side of the tongue. (p＜0.05). Taste qualities of electrical stimuli were also evaluated by using electrogustometer. The major tastes (Approx. 90%) of the feelings for the electrical stimuli were metallic, sour, bitter and salty.

This study was aimed to introduce the measurement of $CO_2$ concentration and leaf area index in the phytotron for predicting the effect of CO.E, light and leaf area index on the instantaneous photosynthetic rate of sweet pepper with the existing ASKAM model. Measurements were made in 2 semi-closed phytotron compartments in which three different $CO_2$ concentrations were applied at random. Plants were grown on containers with circulating nutrient solution at 21$^{\circ}C$ and 80-95% relative humidity. The model estimates crop net $CO_2$ uptake for short time intervals during the day based on short-term data of daily radiation, temperature and $CO_2$ concentration. During the photosynthesis measurements, $CO_2$ concentrations in both compartments and in the basement were measured every minute. This was also done for the flow of pure $CO_2$ into the compartment, global radiation, photosynthetic active radiation inside the compartment, temperature and relative humidity. Crop growth models summarize our knowledge on crop behavior and have as such a wide range of applications in analysis, crop management and thus as a farm management tool.

This study was to research the characteristics of the body shape of Korean woman farmers by the major crops. Four hundred ninety-five Korean woman farmers from 9 different area such as Kumi, Damyang, Iksan, Injae, Chungju, Choongju, Haman, Whasung, and Whasoon volunteered for this study. Their major crops were the rice, the pepper, the water melon, the strawberry, the wild rocambole, the sweet persimmon, the grapes, the mushroom, and the chrysanthemums. Twelve body angles were measured from archived the somatotype photographs of the front, the side, and the back. Questionnaires of SF-36 and the farmer's symptom, and the farm-work related movements were surveyed. The results were as follows; 1. Farmers had lower health levels in physical role limit, pain, vitality, and physical function than other occupational workers. 2. Most farmers acted the high-risk ergonomics motions when they worked in the farm. 3. There were significantly different on the both shoulder angles, the hip tangential line slope, the hip breadth angel, in frontal ankle-knee angle, the bending back angle, the dropping breast slope, the abdominis media angle, under the abdominis media angle, the glutea angle, under the glutea angle, and the sideward knee angle(p<.05). 4. Farmers cultivating the low plants such as the water melon, the strawberry, and the wild rocambole showed more banded vertebralis and side knee angles. Farmers cultivating the red pepper showed the dropping the left shoulder and O shape legs. Farmers cultivating the fruit trees such as the sweet persimmon and the grapes showed the less banded side knee angles than other farmer groups. 5. On comparing the same age, farmers showed the older's body shape in earlier and much more than the old living in the city.

This study was performed to compare the anthropometric and the food and nutrient intake of the adolescents between urban areas and islands in south Kyungnam and to identify their nutritional problems. A questionnaire survey was distributed among 383 middle school students for the food and nutrient consumption and other nutritional attitudes including socioecomonic status. The height and weight of the students were measured as well. Socioeconomic status, such as income, educational level, and jobs of the urban students parents was better than that of the island students. There was no significant difference in height between the students of both areas, but the body weight of the urban male students was far heavier than that of the other group. It is very interesting to note that the energy intake of the urban male students was much lower than that of the island male students. The students of the two areas consumed more protein, Vit B$_1$, Vit B$_2$, niacin and Vit C than the recommended daily allowances(RDA) but the intake of Ca, Fe, Vit A was less. As to the sources of animal fat, the urban males consumed much more. Regarding the taste preference, the study shows that urban male students are more likely to choose sweet, salty and soft tastes than island male students. In the case of female students, although island students prefer a rather hot taste, urban students are more likely to prefer sweet and soft tastes. The favorite foods of urban students are meat products, fastfoods, chocolate, cheese and milkshakes, while foods like cooked rice with assorted vegetable are the favorite of the island students. In general, the preference degree for meat products and fruits rates higher than for vegetables. Conclusively the urban students had a tendency of being obese and the intake of all nutrients by the urban adolescents was much lower than that of the islanders. In this study, the cause can be found in significant differences in consuming animal fat, of taste preference and of choosing favorite food. Accordingly a nutritional intervention or educational program is required to adjust the imbalanced intake of some nutrients for the adolescents in this province.

The objective of this research was to assess the dietary habits, food frequency, and nutrition knowledge of young children who like sweets in the Busan area; the study was conducted using survey method with questionnaires. One hundred eighty three children, aged 8 to 9 years, were divided into two groups: the sweet preference group (SPG) and the control group, based on the subjects' scores for sweets-related dietary habits, sweets preference, and sweets frequency. For dietary habits, the score for eating more snacks than meals was significantly higher in the SPG group than the control group. The SPG group members were also more likely to skip breakfast, have irregular meals, and consume instant and fast food more frequently (p<0.001) than the control group. Nutrition knowledge scores for proper snack intake and proper dietary attitude were significantly lower in the SPG than in the control group (p < 0.05). With regard to food frequency, the SPG consumed more bread, cake, chicken, ham, sausage, hamburger, and ice cream, but less fish, tofu, beans, kimchi, bean sprouts, and milk than the control group. Strong positive correlations were noted between sweets preference, sweets frequency, and sweets-related dietary habits, whereas all of them were correlated negatively with nutritional knowledge. Sweets frequency was related negatively to meal regularity, having breakfast, eating the adequate amount of meals, and recommended food frequency.
