This study was carried out in order to investigate the effect of temperature of treatment and storage on the longevity of 'Unicorn' tomatoes of light red maturity stage during commercial handling conditions encountered while exporting over long distances. Tomato stored at $5^{\circ}C$ and $11^{\circ}C$ temperature with 85% relative humidity by pre-treating handling temperature that was using from field to before shipment as a winter temperature $5^{\circ}C$, spring temperature $11^{\circ}C$ and summer temperature $25^{\circ}C$ for 3 days. On the final storage day, $25^{\circ}C/11^{\circ}C$ (treated/stored) tomatoes showed the highest respiration and ethylene production rate; whereas the lowest respiration and ethylene production rate was found for $5^{\circ}C/5^{\circ}C$ treated and stored tomatoes. Tomatoes treated and stored at $5^{\circ}C/5^{\circ}C$ showed higher marketability, without evidence of fungal rot, decay or spots for 23 days. The fresh weight loss under all treatment conditions increased gradually during $5^{\circ}C$ and $11^{\circ}C$ storage temperatures. The higher firmness and soluble solids were determined from $5^{\circ}C/5^{\circ}C$ and $5^{\circ}C/11^{\circ}C$ treated and stored tomatoes repectively, than from others tomatoes on the final day of storage. In addition, $5^{\circ}C/5^{\circ}C$ tomatoes showed higher vitamin C contents than tomatoes stored at other temperatures, on the final day of storage. As the ripening and storage period progressed, the titratable acidity increased, but declined (P < 0.05) thereafter, due to over ripe tomatoes under all treatment conditions. These results show that $5^{\circ}C/5^{\circ}C$ treated and stored light red maturity stages of 'Unicorn' tomatoes are optimum to export because they show the highest storability and marketability. Moreover, the marketability of light red maturity stage of 'Unicorn' tomato maintained for 2 weeks in $25^{\circ}C/11^{\circ}C$ treated and stored temperature that might be the export temperature from Korea to Japan in summer season. This research result could be useful in helping tomato growers and exporters to get optimum market value by satisfying the buyer and consumer with a fresher product.

It is important to determine the optimum harvesting time that impact decisively on the quality of vegetable waxy corns. In general, it takes 20~25 days from silking to harvest according to ecotype when waxy corn hybrids were sown in April. We identified the optimum harvesting time by the ecotypes and seeding dates for the establishment of corn double cropping system of waxy corn. It takes 23~25 days from silking to harvest regardless of ecotype, when waxy corns were sown at early in April or late in June. It takes 28~31 days when Chalok1, early maturing type, was sown between in July 10, and in July 30. It takes 29~31 days when Ilmichal, medium late maturing type, was sown between in July 10 and in July 20, but 39 days were required when sown at in July 30. The cumulative temperature for harvesting was about $1700^{\circ}C{\sim}2100^{\circ}C$. The minimum cumulative temperature from seeding to harvest was approximately $600^{\circ}C$. These results will be helpful to the farmers for determining the optimum harvest time of vegetable waxy corns.

A total of 30 pigs (average 60kg) were used to investigate the influence of breeds on meat quality. Pigs were alloted into one of three experimental groups [A (Landrace×Yorkshire×Duroc), B (England Berkshire), and C (Kagoshima Berkshire)]. Pigs were slaughtered at approximately 110kg of live weight for measurement of meat qualities. Crude protein was significantly higher in B than those of other pig breed groups. Shear force value was higher and pH was lower in A than those of other pig breeds. In color, C was significantly higher in a* of meat color and lower in b* of fat color and in brittleness, hardness, springiness, chewiness as compared with other pig breeds. Essential fatty acid were significantly higher in A and lower in B than those of other pig breeds. Aspartic, threonine, serine, glutamic and phenylalanine were higher in C, whereas glycine, alanine, cystine, valine, leucine, tyrosine, histidine, lysine and arginine were significantly higher in A. In sensory evaluation of fresh meat, color was significantly higher in C. However, moisture, crude fat, crude ash and drip loss, marbling score, overall acceptability of fresh meat and all items in sensory evaluation of cooked meat were not significant difference among the pig groups. In conclusions, loin from Kagoshima Berkshire had the lowest shear force and the highest a* value. In the current study few effects of pig breeds were observed. Further studies are needed on the relationship between physico-chemical properties and the pig breeds.

The preservation efficiency, quality and utilization of silage from 3 species of pumpkins (Mammoth pumpkin, Queensland blue pumpkin, Korean pumpkin) without and with 10, and 20% wheat bran additive were studied in this experiment. Silages were analysised and tested the chemical composition, pH and quality of silages between at 40-60 days and egg performance were carried out with mammoth pumpkin silage without additive. The results were summaried as follows. 1. The losses of all silage ware lower and similar as about 15% at 6 monthes following after silage-making but all raw pumpkins were spoilaged during the winter storaging. 2. The moisture content of silages were higher as about 97% in mammoth pumpkin silage, 94% in Queensland pumpkin silage and 91% in Korean pumpkin silage without additive and all nutrient content of silage without and with additive were depended on its content of raw silage material of pumpkins and wheat bran. The contents of moisture and N-free extract were slightly decrease but not significantly difference during the silaging and other contents were not so much changed. 3. Good quality of silage were made from all pumpkins with and without additive. Organic acid contents were 2.09-2.93% of lactic acid, 0.68-1.71% of acetic acid and 0% of butyric acid and it was pH 3.8-4.0 in silages. 4. Feed intakes, egg production and quality of egg were showed good result in 5.0 and 7.5% silage feeding group as D.M. base for egg performance. (P<0.01) 5. It was concluded that good quality of silage were made from pumpkins with and without wheat bran additive and it was suggested that poor quality feedstuff may be improved it feeding value by extended palatability with pumpkin additive silage.

This study was to investigate the consumption pattern and nutrition knowledge about vegetables of 184 housewives attending the school of adult and continuing education attached to DukSung Women's University. The results were summarized as follows; the average vegetable expenses were $10,000{\sim}20,000$ won per week. The frequency of purchasing vegetables was $2{\sim}3$ times a week. Respondents usually bought the vegetables at local markets and supermarkets. As for buying vegetables, all of respondents kept in mind all the time the organic vegetables were better. The price was the most important factor of their purchase in the low income households. In the family, the vegetable dishes were favored by housewives most and by sons least. Among the vegetable cooking methods, Kimchi was the most frequently used and salad was the least. Forty four percent of the respondents experienced purchasing ready made vegetable dishes in the market. The reason they bought ready made ones was the special taste of the dishes. The rest of respondents never bought cooked vegetable dishes because they thought the dishes unsanitary. Twenty seven percent of the respondents experienced purchasing. The reason for not purchasing Kimchi was the housewives' traditional prejudice of buying Kimchi in the market. Respondents have a considerable knowledge that 42 kinds of vegetables could be good for certain disease and 10 kinds of vegetables might be harmful for certain disease.

The present study was undertaken to examine if the carcass and pork quality of finishing pigs reared on a low plane of nutrition (LPN) could be improved compared with that of the pigs finished on a high plane of nutrition (HPN). Sixty-eight crossbred (LYD) barrows and 68 LYD gilts weighing approximately 50 kg were fed a diet containing 3.54 Mcal DE/kg with 1.00% lysine (HPN) or 3.02 Mcal DE/kg with 0.68% lysine (LPN) in eight pens up to approximately 120 kg and slaughtered. The belly, loin, ham, and Boston butt were cut out from a total of 20 carcasses, after which physicochemical and sensory quality attributes of the belly and the representative muscle of each of the loin, ham, and Boston butt were evaluated. The ADG, gain:feed ratio, and backfat thickness were less for LPN than for HPN (p<0.05). The cooking loss, hardness, and chewiness values for the Boston butt were less for LPN vs. HPN. In sensory evaluation for fresh meat (muscle), the subjective quality scores were greater for LPN vs. HPN in color, marbling, and acceptability for the loin, the muscle:fat balance score for the belly tending to be greater for LPN (p<0.10). In addition, LPN was superior to HPN in the flavor and juiciness in sensory evaluation for cooked ham. In conclusion, the present results suggest that the carcass and pork quality of finishing pigs could be improved with reduced growth performance by using LPN.

Oyster mushrooms are an economically important crop, accounting for 35% of the total mushroom production in Korea. In this study, we developed a new cultivar of Pleurotus ostreatus, known as 'Baekseon,' which is characterized by a white pileus with a white stipe. It was bred by mating monokaryons isolated from white mutant oyster mushrooms that were naturally generated from 'Gonji-7ho' and 'Wonhyeong-1ho' at the Mushroom Research Institute, GARES, Korea in 2018. The optimum temperature for mycelial growth on potato dextrose agar medium was approximately $28-31^{\circ}C$, and the optimum temperatures for primordia formation and growth of fruit bodies on sawdust media were $22^{\circ}C$ and $20^{\circ}C$, respectively. The time required for the bottle-cultured mushrooms to complete spawn running, primordia formation, and growth of fruit bodies was 30 days, 4 days, and 4 days, respectively. The fruit bodies were bundle-shaped, the pilei were round type and white, and the stipes were white. The stipes were slender and longer than those of the control ('Miso'). In the productivity test, the yield per bottle was 185 g/1100 mL, which was 45% greater than that of the control ('Miso'). In the farm test, the yield per bottle for Farm A (Pyeongtaek) and Farm B (Yeoju) was 184 g/1100 mL and 178 g/850 mL, respectively. With regard to the physical properties of fruit bodies, the springiness, cohesiveness, gumminess, and brittleness of stipe tissue were 80%, 57%, 720 g, and 57 kg, respectively. These values were lower than those of the control ('Miso'). To test the shelf life, the fruit bodies were wrapped with antifogging film and stored at $4^{\circ}C$ for 28 days and then at room temperature for 4 days; such conditions were sufficient for maintaining edibility.

This study was carried out to investigate the utilization value of legume crops collected in tropical and subtropical areas. We examined agronomic traits to assess domestic adaptability and evaluated useful components of foreign legumes. We used a total of 201 genetic resources of three legumes, consisting of 68 lentils, 72 chickpeas and 61 guars. The average number of days to flowering of the three legumes ranged from 56.7 to 60.8 days; the shortest in guar and longest in chickpea. The average number of days to growth of the three legumes ranged from the shortest 86.8 days in lentil, to the longest 163.9 days in guar. The maturation period of the three legumes lasted from the end of May until mid-September, based on sowing in March. However, the average yield of lentil was very low, ranging from 0.5 g to 30.6 g, with an average 16.4 g based on 10 plants per accession. The average 100 seed weight of the three legumes was 2.2 g for lentil, 22.9 g for chickpea, and 3.8 g for guar. The crude protein content ranged from 14.1% to 32.4% with an average of 20.4%, the highest for guar and the lowest for chickpea. The average crude oil content in the three legume crops was generally low, ranging from 0.8% in lentil, to 4.3% in chickpea. The average dietary fiber content in the three legume crops varied from 15.7% to 50.7%. Guar was the highest source of fiber, followed by chickpea (19.3%) and lentil (15.7%). From the agricultural traits analysis, chickpea and guar could grow domestically. However, lentil was difficult to flower and fruit normally during the warmer season after May. Therefore, lentil should be considered for late summer cropping during the cool season. The physicochemical properties of the three legumes seem to be useful as they are similar to, or better than, those of the control common bean.

The purpose of this study was to propose an alternative for the eating habits of modern people and coping with the diseases. The purpose of this study was to apply the principles of eating habits of people living in Roma Linda to modern dietary life and to help healthy life and prevent disease. The period of this study was from May 1, 2016 to February 28, 2018. Literature search was conducted using Pubmed and Korean academic web sites. Based on the recognition of wrong eating habits, we classify and classify diseases according to eating habits. A total of more than 100 papers were selected and 60 papers and a database were prepared. People living in Roma Linda have eight health principles. The Roma Linda practiced balanced nutritional intake, sufficient exercise, adequate water intake, sunlight, temperance (abstinence from alcohol etc.), fresh air, adequate rest, and trust in eating habits. People living in Roma Linda have a high intake of vegetables, fruits and nuts. People living in Roma Linda are educated about nutrition, and among them, there is a low prevalence of coronary heart disease and cancer, because they mostly do not smoke or drink alcohol. Unhealthy eating habits and dietary behavior are associated with many diseases. Many chronic, degenerative diseases are due to bad eating habits and stress. If you take good food habits of people living in the Roma Linda area and practice it steadily, it will have a great effect on disease prevention.

This study explored the architectural nature, the thought reflected in the place and the 'meaning-landscape' characteristic of a place, to where a retired scholar had lived. The object of the study is the Maechun-Byulup Toesu-jeong wonlim, which consists of a summer house and a garden forest. The results of the study are as following. Toesu-jeong wonlim is located at Daejeong-ri, Sannae-myeon, Namwon-si. It had been built by Maechun Park Chi-Gi in 1870 for his residence after retirement. It is a villa type pavilion and a garden forest which have Banseondaegi(伴仙臺記), Banseondae-10-yeong, Toesu-jeong(退修亭) Sangryangmun, a writing dedicated when putting up the ridge beam of a wooden house), Toesu-jeong Wonwun Byeongsoseo, hanging boards and tablets with poems written on them. In the Toesu-jeong wonlim, there are various 'meaning-landscapes' such as the Maechun-Byulup, Banseondae, Yabakdam and Simjinam together with engraved calligraphy related to the landscaping culture. It is also possible to find the remains of beautiful engraving on the stones and woods at Goksoo Yoogeo(曲水流渠) that suggest the banquets they had while discussing the elegant tastes and appreciating the landscape. The Toesu-jeong wonlim consists of the Toesu-jeong area(a pavilion), the Gwanseon-jae area(a shrine) area and the Gyejeong area(a garden with a brook) area. The pedantic 'meaning-landscape' elements, as the residence of retired scholar who spent his remaining life with elegant tastes, and the expertise of Maechun Park Chi-Gi, as a landscaping architect who built a villa and a garden forest in the motif of a Taoist hermit, can be extracted through the Banseondae-10yeong. The Banseondae-10yeong is the first Toesu-jeong poem and consisting of the Samseon-dae, Sejin-dae, Samcheong-dam, Yabak-dam, Samseo, Takgeum-dam, flat stones, caves, stone sculptures and harvest. The existing vegetation and plants in the Toesu-jeong wonlim are; natural pine forest in the rear garden, zelkova trees, wild cherry trees, apricot trees and pine trees bent to the waterfront direction. Except some ornament-species and shielding-species such as the poplars, most of current trees and vegetation keep the shape of the original Toesu-jeong wonlim landscape.
