This study attempts to analyze the physicochemical characteristics of rice flour developed as rice powder for exclusive use, steamed rice cake recipes developed as basic recipefor rice cakes. The study also aims to compare the quality characteristics of steamed rice cakes in an effort to establish the possibilities of developing various rice cake recipes. The moisture content and amylose content increased as the rice powder particles for exclusive use became finer. With regards to water uptake, in the case of the Hungara type, the water uptake increased as rice powder particles increased in size. In the case of the Shingil and commercial types, the water uptake decreased as rice powder particles increased in size, and solubility and swelling force decreased as rice powder particles increased in size. In the case of chromaticity, Sulgidduk made with rice powder for exclusive use the brightness (L value) increased as powder particles became finer and the yellow indexes (b value) decreased, and this was especially pronounced in the Shingil type. The measurements of changes in the mechanical textures of Sulgidduk showed that rice types with larger particles led to lower hardness, cohesiveness, springiness, and chewiness.

Cowpea(Vigna unguiculata L. Walp) has a low fat and protein content and a relatively high starch content, so it is mainly used in various ways for song-pyeon sediment, rice-cake paste, and porridge. In Yeonggwang-gun, Jeollanam-do, cowpea for seed production is being cultivated for the localization of raw material for Rice cake with ramie leave. A cowpea variety 'Jang-Alchan' was improved from the cross between IT145373 and IT145391 at the JARES in 2019. 'Jang-alchan' has an erect plant with an intermediate plant habit, light purple-colored corolla, and heart-shaped leaflets. 'Jang-alchan' has an orange-yellow seed seed-surface of faint luster, and brown and straight pods when matured. The stem length of 'Jang-alchan' was 48cm, 9cm longer than that of the control cultivar 'Okdang' and the 100-seed weight was 14.1g. The weight ratio of the seed coat for the entire seed was 11.2%, which was 0.2%p lower than that of the control cultivar. Field resistance of 'Jang-alchan' to leaf and systemic diseases was similar to that of the control cultivar. Is field resistance of 'Jang-alchan' to lodging was slightly lower than that of the control cultivar. The average yield of 'Jang-alchan' was 1.85ton per hectare, which was 14% higher than that of the control cultivar 'Okdang', 'Jang-Alchan' does not require the installation of an espalier-net and is taller than the existing supplied 'Okdang', so it can be harvested by combine harvesting. In addition, it is expected to contribute to the localization of raw material grains for regional specialties as it can be cultivated over a large area.

일본(日本) 내량시대(奈良時代)를 대표(代表)하는 춘일대사(春日大社) 약궁제(若宮祭)는 한반도(韓半島)와 종교적, 문화적 문류(文流)가 빈번하던 시대에 형성된 등원가(藤原家)의 씨사(氏社)로서의 제사이며 역사적(歷史的)으로도 백제인(百濟人)과의 관계가 밀접하여 삼국시대(三國時代)의 식생활(食生活)을 연구하는데 좋은 자료가 되리라 보아 조사한 것이다. 1. 좌속신(坐俗神), 불교(佛敎), 유교식(儒敎式) 제사(祭祀) 및 경사스런 축하연에 쓰이는 종이, 실크, 떡으로 만든 조화(造花)장식은 최초에는 계절에 맞는 생화(生花)를 쓰다가 차츰 다양하게 변화했음이 보인다. 본(本) 약궁제(若宮祭)에서의 도라지꽃은 한반도에서 쓰여진 흔적이 없으나 일본(日本)에서는 제사(祭祀)로 쓰였다. 2. 소(小), 대어반(大御飯)은 시루떡의 시작이였고 백미(白米) 이전에는 현미(玄米)로 만들었다. 다시 쌀 외에 찹쌀, 팥 등 여러가지 곡물을 가미하게 됐다. 3. 채소의 종류는 근채류(根菜類)가 귀중한 채소로 꼽혔고 극히 단순한 조리법이였으리라 본다. 4. 당과자(唐菓子)는 쌀가루를 여러가지 형을 만들어 쪄서 튀겨서 먹는 것으로 보아 그 이후의 과자와 전병의 원조임을 알 수 있다. 5. 8의 어과자(御菓子)에서 둥근 메떡은 현재의 절편이나 가래떡의 시작이였으며 일본(日本)은 기호상 찰떡으로 변했다고 본다. 6. 제사에 최근에도 쓰여지는 곶감, 밤은 고대(古代)부터 이어온 식품으로 밤은 그 껍질채로 쓰여졌고 그 외의 그 지역에서 생산되는 갖가지 과일이 쓰여진 것으로 본다. 7. 염분(染分)과 사색(四色)은 적(赤), 황(黃), 청(靑), 백색(白色)을 말하며 그 색채가 원시적인 선명한 색깔로 본제(本祭)의 상징이며 대표적인 제물이다. 한반도에서는 과자, 사탕, 떡, 과일 등을 주로 이 4가지 색깔로 물들여 제사뿐만 아니라 경사스런 잔치에도 높이 고여서 축하의 뜻으로 차렸다. 8. 성물(盛物)에서는 검은콩, 흰콩, 팥, 비자로서 그 당시 중요한 곡물로서 나타났다. 9. 술은 청주(淸酒)를 쓴 것으로 보아 이미 그 시대의 고도(高度)의 제조법이 백제로부터 전해져서 현대까지 이어지고 있음을 보여준다. 끝으로 신찬(神饌)과는 직접적인 관계는 없으나 사진 1, 2, 3에서 보여주듯이 직접 본(本) 행사(行事)에 참여하면서 제단형태, 의상, 절차, 그 외의 음악과 무용, 장식 등이 현존하는 한국의 전통적 풍물과 그 분위기에 이르기까지 밀접한 관계가 있었음을 느낄 수 있었다는 점이 본 제사를 통하여 고대식(古代食)을 추정하는데 간접적인 뒷받침이 될 수 있다고 보았다.

A group of 132 pre-school children with a mean age of six years and one month was the subjects of this investigation. These children were members of three nursery schools locating in Kwang-ju city. Each child's mother replied to a questionaire which included 42 food items and 4 questions. The results showed that the food preference of each child was variable and the group as a whole expressed more positive than negative feelings. The average number of foods liked per child was 22.9(range: $7{\sim}42$) among 42 food items. Peach, Apple, Strawberry, Laver, Egg, Tomato, Sweet Potato, Tangerine Orange and Beef were ranked in descending order of 'like' ratings. The average number of foods refused was 4.9 (range: $0{\sim}25$). Onion, Liver, Red Pepper Leaf, Root of Bellflower, Taro, Wild Seasame Leaf, Egg Plant, Cabbage, Water Cress and Bracken were ranked in descending order of 'refuse' ratings. The odor of hurting feelings, the hot taste and the flabby texture were the reasons why the children refused these foods. The average number of foods unexperienced was 4.4 (range: $0{\sim}14$). Kidney, Dried Small Whitebail, Tangle (DA SHI MA), Liver, SA RI Mushroom, Acorn Mook, Dried Fragrant Mushroom, Pine Agaric, Root of Bellflower and Ped Pepper Leaf were ranked in descending order of 'unexperience' ratings. Children's 'like' rating toward total foods was 57.3% and the 'refuse' rating was 11.7%. Among eight food groups, fruits showed the highest favority (91.4%) and mushroom showed the least (25.9%). The difference between male and female in the preference of total foods did not showed significant level. But the difference were significant in those of individual food groups; other vegetables, green and yellow leafy vegetables, mushrooms(above, p.<01), fishes and shellfish and sea weeds (above, p<.05). Children who had experienced meals missed rated 59.1% and 34.1% of these children missed meals once a week. The main reason for maels missed was due to the heavey snacks before meal time. Children who had snacks twice a day rated 45.6%. Main foods used as their snacks were starch foods (Cake, Biscuit, Sweet Potato) and citrous foods (Fruits, Apple, Tangerine).
