This article examined the different types of Jeonuhwa as recorded in 16 royal palace studies from the Joseon dynasty (1392-1909). The ingredients used in Jeonuhwa during the Joseon dynasty were categorized as follows: 16.0% for gray mullet(秀魚) and fish(生鮮), 14.2% each for liver and cow stomach, 12.3% for sea cucumber(海蔘), 4.7% each for crab(蟹), clam(生蛤), and chunyup(千葉), 3.9% each for pork meat(豬肉), octopus, 2.8% each for oyster(石花), pheasant(生雉), and chicken(鷄), 2.0% each for croaker(民魚), and brain (骨), 0.9% each for duck(鴨子), pigeon(山鳩), dobi(都飛), snapper, white fish(白魚), mussel(紅蛤), haeran(蟹卵), quail(鶉鳥), egg(鷄卵), and sesame(實荏子). This observation may be associated with commercial industrial development that prevailed during the late Joseon dynasty. Further studies will be conducted on recipes and ingredients recorded in Euigwe in order to develop a standardized recipe for Jeonuhwa.

The purpose of this study was to investigate development and nutrient analysis of traditional food in the Sunchang area. A total 6 kinds of set tables was excavated from storytelling. Among set tables, taste and season food were the best in Sunchang gochujang hanjeongsik and Sunchang arirang season table. Shape color, smell, and commercialization possibility and differentiation were best in Sunchang arirang season table. Mole Ratio of sodium and potassium was 1:1 in Sunchang gochujang hanjeongsik and Sunchang arirang season table. The calcium contents in Sunchang gochujang hanjeongsik and Sunchang arirang season table were higher than other traditional foods. This result indicated that Sunchang gochujang hanjeongsik and Sunchang arirang season table are useful for traditional functional food. Also, it is highly suggested to make a database system about local food and standardization of traditional foods cookery.

This study was performed to investigate the effect of rearing period(45 and 70 days) on the changes of the yield, physical trait and the composition of fatty acids. The average weight of 100 duck meat at 45 days post hatch was 2.2kg. The yield of meats from prime cuts of 2.1kg, which are the most consumed today, was composed to whole legs($14.1\%$), wings($8.7\%$) and breast(12.5\%$). The ratio of whole legs and breast was similar, In the secondary cuts, the meats was consisted in drumstick($12.5\%$), thigh($7.3\%$), breast($11.7\%$), tender lion($0.8\%$), drum matte($4.9\%$) and wing($2.6\%$). Especially, the drumstick was twice higher than the wing. The content of oleic acid was 50.87 to $51.32\%$ and 49.84 to $50.03\%$ in the breasts and leg, respectively. In the breast, meat at 75 days the oleic acid was slightly increased DHA was not detected in the breast meat, However, it was $0.13\%$ in the leg. The $a^{*}$ value in meat color, ranged was 16.67 to 17.92 in the breast and 15.81 to 17.15 in the leg. Statistically, there was no significantly difference between the breast and leg. The cooking loss of the breast and leg was $26.37\%\;and\;30.32\%$, respectively. The shear force value was $2.20\;kg/0.5inch^2$ at 45 and $2.84\;kg/0.5inch^2$ at 75 days post hatchet respectively. Therefore, the raring period was effect on the shear force value, but not on the cooking loss and meat color.

The aim of this study was to determine the chemical traits of duck meats with different rearing periods(45 70 days). The content of protein was 21.3 and 19.61% in the breast and leg at 70 days post hatched, respectively. Group at 70 days showed high protein composition than those of 45 days group. The content of fat was slightly increased with the rearing periods. The composition of Ca, mineral compound, was not showed the difference between leg and breast meat. However, it was increased with the rearing periods. The composition of Fe was not significantly different in the breast meat. However, there was a significant increase in the leg (p<0.05). It was compared 14.6 ppm at 45 days group to 27.5 ppm at 70 days group. The content of methionine was significantly increased in the breasts due to the increasing rearing periods (p<0.05), but not in leg meat. There was no significant difference between parts, but glutamic acid content was significantly decreased along with the increasing rearing periods (p<0.05). The content of collagen at 70 days(0.77 g/100 g) was higher than those of 45 days(0.65 g/100 g). It was affected by the rearing periods In the wing-removed skit, it was 0.15 g increases at 70 rearing period group. The cholesterol content was significantly increased in the leg but not in the breast. With the rearing periods, it was significantly increased in the leg (p<0.05).

The vegetational and environmental history of Korea during the Holocene period has reconstructed by the use of folral, palaeoclimatogical, archaeological data and written records. From 10,000 to 6,700 yeat B.P. in mid-eastern Korea, deciduous broadieaved trees gradually increased trees, notably at c.8,000 years B.P. From 6,700 to 4,500 years B.P., the vegetation remained dominated by Quercus and pinus(Diploxylon). Vegetational informations suggest the postglacial hypsithermal from c.8,000 to 4,500 years b.p. After 4,500 until 1,400 years B.P., the admixture of cryophilous trees in midland and thermophilous trees in south seems to imply the latitudinal divisions of vegetation and climate. The presence of cultivated rice pollen as well as non-arboreal pollen and spores indicates an increased rate of deforestation. From 1,400 years B.P., there was a sharp decrease in the representation of temperate trees, but the presence of the cryophilous genera Abies and pinus (Haploxylon) is noticea-ble and might be related to the occurrence of Little Ice Age. Fossil pollen diagram from western Korea and eastern Korea since 6,250 and 10,000 yeats B.P., respectively have enabled to compare vegetational dis-tribution patterns and changes in the Holocene period. In western Korea, Alnus- dominated vegetation continued from 6,250 to 1,500 years B.P., but pinus took over Alnus from 1,500 years B.P. In eastern Korea, however, Quercus and pinus dominated from 10,000 to 2,000 years B.P., but pinus be-came predominant from 2,000 years B.P. On a time- spatial basis, different vegetational distribution pattern can be recognised between western and east-ern Korea. The use of seven historical records which is unique to Korea also enabled to reconstruct the distributional pattern and temporal change of vegetation from 1425 to 1928.

AMS radiocarbon dates indicated that Eurimji reservoir, located at Jecheon City, Chungbuk Province, has been formed during the late Holocene Epoch. The sedimentary sequence at bottom reveals histories in hydrology, climate conditions and past vegetation dynamics. Ages controlled sedimentological and palynological analyses on ER 3-1 Core contribute to reconstruct paleoclimate and past hydrological conditions. These analyses suggest that lower interval (307.5m~309.5m elevations) of the ER 3-1 Core was deposited in stable from 1,920 yrBP to 1,420 yrBP, but upper layer sediment above these elevations was composed of reworked sediments during the pre and post 2,000 yrBP. Pollen assemblage indicates that watershed vegetation of the Eurimji reservoir, during the period of 1,920 yrBP~1,420 yrBP, was closely comparable to modern vegetation dominated Pinus and Quercus mixed vegetation. Also, riparian including Alnus, Fraxinus and Salix were inhabited along the banks of stream, and aquatics such as Typha, Nymphaea and Persicaria flourished at shore of the reservoir. According to cultural chronicle, it infers that the Eurimji reservoir was formed from the Bronze Age to the Iron Age or the beginning of ancient society. An integrated data suggested that Quercus-Pinus-Abies mixed forest flourished under cool and dry climate conditions during 3,200 yrBP~200 yrBP.

This study was to investigate regularity of breakfast and food habits of commuting local college students. The regularly breakfast eating rate was found to be 32.9% in man and 26.5% in woman. The mean score of food habits was pretty low, 36.7 out of minimum possible score 12 and maximum 60. The mean score of nutrition attitude was 58.1 out of minimum possible score 18 and maximum 90. This survey showed that skipping breakfast or irregularity of breakfast led to overeating, high fat diet, lot of alcohol and imbalanced diet. It was known that breakfast was the most important among three meals. But having balanced breakfast daily was very difficult according to loss of appetite and busy schedule early in the morning. I suggested carbohydrate food, protein food, and vitamin & mineral food items desirable for nutritionally balanced, easily digestible, tasteful, quick and easily cooking breakfast menu. It was recommended to choose on item out of each of three food categories considering calory(1/3 of daily recommended calory intake for breakfast).
