Background: Recently, jujube (Zizyphus jujuba Mill.) has been attracting attention as a fruit, and its cultivation in rain shelter house is increasing to produce the high quality fresh jujube. This study was carried out to investigate the growth and fruit characteristics of jujube according to the types of rain shelter house. Methods and Results: The characteristics of 5-year-old Bokjo cultivar cultivated in 3 types of rain shelter house, multi span rain shelter house with roof vent (Type I), single span house with a column in the center and roof vent (Type II) and single span house with a column in the center and without roof vent (Type III), and open field were examined. The sprouting and blooming period were different among the types of rain shelter house. The diameter of main stem was higher in rain shelter houses than in the open field. There was no a significant difference in fruit number per leaf stem among the types of cultivation. The incidence of fruit cracking in open field cultivation which was 51.2% was much higher than that in Type I 21.6%, Type II 19.3%, and Type III 25.5%. The fruit size and weight in rain shelter houses, especially in Type III rain shelter house were higher than those in the open field and the soluble solids content of fruit in Type I and Type II was higher than in Type III rain shelter house and the open field. Conclusions: The results show that the growth and fruit quality of jujube were improved by cultivation in rain shelter house, and affected by the types of rain shelter house.

This study was carried out to investigate the effects of rain-shelter types on growth, and fruit quality of red pepper (Capsicum annuum, 'Kemmaru') cultured in paddy. Applied rain-shelter types were outfield (control), simple rain-shelter plastic house with 2 rows (2R), simple rain-shelter plastic house with 4 rows (4R), and perfect plastic house (House). The plant height was the highest in Houses treatment. There was no difference in leaf length and width among the rain-shelter treatments. The fresh and dry weight of red pepper was high in order of House > 4R > 2R > Control. The ASTA value is irregular tendency among the treatments. Hunter's color value 'a' and 'b' was not different from among the treatments. Phytophthora blight, powdery mildew, bacterial spot were not occurred in all of treatments, and Anthracnose was only occurred in control. Mite, Microcephalothrips abdominalis, and Bemisia tabaci were not occurred in all of treatments, and aphid, Helicoverpa assulta, and virus were occurred all of treatments as same degree. Our results will provide rain-shelter cultivation of red pepper can be increase dry yield and decrease disease and insects.

This study was conducted to find the effects of microclimates such as air and soil temperature, photosynthetic photon flux density (PPFD) on the berry development and physiological property between cultivation conditions (open field and rain shelter house) in 'Northland' blueberries (Vaccinium corymbosum). The rate of berry growth and development was stimulated in plants grown in rain shelter house, thus, berry reached to the ripe stage about one week earlier than those in open field. Berry weight and size at ripe stage seemed not affected by microclimates. However, total soluble solids content was higher in berries from open field whereas the titratable acidity was significantly higher in berries grown in rain shelter house. Berry firmness at ripe stage was little affected by growing condition. Total anthocyanin content of ripe berries was higher in berries harvested from rain shelter house. Total phenolics content and anti-oxidation activity of berries were higher in open field than those of rain shelter house during berry development but no differences were found at ripe berries.

This study was conducted to investigate the plant growth and seed yield between rain-shelter plastic house and out-door cultivation, and analysed the effect of harvesting time on seed quality. In rain-shelter plastic house cultivation, emergence date was 3 days and flowering date was 8 days earlier than out-door cultivation. Seed yield of rain-shelter plastic house cultivation was increased $25\%$ compared to out-door cultivation and it's more beneficial than out door cultivation. The crude fat content was higher and seed was whiter and better quality in rain-shelter plastic house cultivation than out-door cultivation. In out-door cultivation, the crude fat content was steadily increased until 40 days after full bloom, but the seed color was getting dark which was harvested at 30 days after full bloom and the color was turn to the dark brown when the seed was harvested at 40 days after full bloom. Harvesting of safflower seed's quality is best between 20 days and 30 days after full bloom.

This study was carried out to establish a production system of cut flowers and bulbs of oriental hybrid lilies in highland in summer. In study, effect of cultivation type and shading was examined. The cultivation types used in the bulb production experiments were greenhouses with no cover, greenhouses with net screen (net screen house), and greenhouses with EVA roof cover and net screen sides (rain shelter house). Net screen and rain shelter houses had either 0 or 30% shading. Cultivation type had significant effect and shading had a minor effect on bulb production. The greatest yield and quality of produced bulbs were obtained in the rain shelter house with 30% shading. From the results of this study, it is concluded that dispersed production of high quality cut lily flowers and bulbs could be achieved during the summer in highland.

This experiment was carried out to investigate the effect of rain shelter cultivation on the its quality of safflower. The development and growth of safflower, especially the number of secondary branches per plant was increased by rain shelter. Under the rain shelter started earlier, the seed yield was increased by 95% compared with that of non-shelter condition. The number of plants in a unit area the number of flower buds and seeds per plant and seed weight were increased in rain shelter condition. As those plants were cultivated under the rain shelter, lightness(L) of their seeds was increased but redness (a) and yellowness (b) were decreased.

This research is related to house entrance recognition of residents, who have long kept the entrance without a closing door in Eoeun village, Geumho, Keongbook. The purpose of the research was to interpret the recognition of a house entrance in Eoeun village with the theories of cultural ecology. Final results suggest the belief for all the inhabitant\`s welfare through anthropological adaptation to habitat. The fish in the Geumho River had sought the shelter from the heavy rain in summer. The Eoeun forest at the entrance of the village provided good shelter for the fish. The Eoeun residents thought that the safe shelter fur the river fish is also semantic for the people. They believed that if the fish could not find shelter, i.e., the Eoeun forest and left, the village could be not safe for their life. Therefore, even the entrance of house should be structurely opened for the fish shelter in a symbolic sense. The entrance without a closing door has implied that their life should depend upon their natural environments because they have believed that till now there have been no considerable accidents in the village.

The flowering season of jujube (Zizyphus jujuba var. inermis (Bunge) Rehder) is overlaps with the rainy season and the abnormal weather conditions in Korea, thereby affecting pollination, fertilization, and fruit setting. We studied the pollinating activities of Apis mellifera L. and Bombus terrestris L. in rain shelter houses and their effects on fruit setting, with the ultimate aim of stabilizing fruit setting in Z. jujuba. A. mellifera and B. terrestirs were used for pollination in jujube orchard in the rain shelter house for approximately 55 days from June 1, 2016, to July 25, 2016. The peak time of the rate of outgoing and incoming A. mellifera was recorded in the afternoon. However, the diurnal activity of B. terrestris was constant between 09:30 and 17:30 h. The rate of jujube fruit set on current shoots by A. mellifera and B. terrestirs was 10.2 and 8.9%, whereas that in plots with no pollinators was 5.5%. Therefore, using pollinator in the rain shelter house in jujube orchard is effective in promoting jujube fruit setting.
