There are variations among grapevine genotypes in the levels of tolerance to cold, and cold-hardiness of grapevine has been affected by the change of short-term environment during over-wintering. In this study, the responses of vines to cold in open field and rain-shelter system were investigated to obtain useful information in increasing the tolerance to cold in grape cultivation. Total carbohydrate content of bearing mother branches was higher in the rain-shelter system than in the open field, and lower in the branches of 'Muscat Bailey A' than in 'Campbell Early' and 'Kyoho'. Bud-burst and shoot growth were better in the rain-shelter system than in open field, whereas there is no significant difference among the treatments of net beside vines. There was also low incidence of gray mold in rain shelter system. Stilbene compounds such as t-piceid, resveratrol, piceatannol, c-piceid were accumulated in the cold-treated shoot from vine cuts harvested in rain shelter system. Genes of chalcone isomerase, manganese superoxide dismutase, proline rich protein 2, and temperature induced lipocalin were highly expressed in the cold-treated shoot from vine cuts harvested in rain shelter system. While there was not change of air temperature, but high reduction of wind speed in the rain shelter system compared to open field, and increase in the reduction of wind speed by net treatment. The damage of grapevines by cold in the extreme low temperature could be reduced by keeping them in the rain shelter system with net during winter season.

Asparagus varieties popular in the foreign countries were collected and tested on their productivities and qualities for five years under rain shelter and open field conditions. Among the tested varieties, cultivars of UC309 and Excel showed superior productivity to the others in spear weight but the initial growth was not different among the tested varieties. However, the growth index was higher than the other varieties. According to the result from eight-year experiment, the best variety in productivity and quality were UC309 and Excel both for rain shelter and open field cultivations. To avoid the damage caused by stem blight, rain shelter and soil surface mulching treatments were tested with var. Excel. The spear sprouting and first harvesting date were a few days earlier in rain shelter cultivation than in open field, but there were no differences among the mulching materials. The number of spears and the spear weight per plant were increased in rain shelter cultivation, especially with rice straw and black P.E. mulching treatments. Marketable yield also increased by 253% in black P.E film mulching in rain shelter cultivation compared to non-mulching in open field. The stem blight examined in the autumn, 1997 was not observed under rain shelter treatment, but severe damage was observed in the open field regardless of the mulching materials. In the experiments, high asparagus yield could be achieved by black P.E. film mulching in rain shelter cultivation without the occurrence of stem blight.

Growth and tuber development of ‘Black Magic’calla lily as affected by the rain shelter with 50％ shading and the tuber size were investigated. Tubers of five grades in size were cultivated in the rain shelter or in the open field (control). Days to emergence of shoots in the rain shelter was accelerated by 4.2 days as compared to the open field. Emergence ratio was higher as the tuber was larger, tubers grown in the rain shelter showed the significance in the growth characteristics as compared to the control. There were no significant differences in the number of flowers per tuber between the rain shelter and the open field. Flower quality was 12.2 cm longer than that in the open field. flowering characteristics was improved with the increasing tuber size. Low infection of soft rot disease of 3∼22％ was found in the rain shelter as compared to the that of 19∼83％ in the open field. Thus tubers produced under the rain shelter showed improved quality, Even if the small tubers with diameters of 0.5∼1.0 cm were cultivated in the rain shelter, the weight and diameters of tuber harvested after approximately 7 months were 50.2 g and 5.7 cm, respectively.

The purpose of this study was to analyze the village groves in Pohang city by classifying them into 5 categories: sage plantation, shelter-belt plantation, shore plantation, ornamental plantation and bower plantation. The results of this study can be summarized as follows; The village groves in Pohang city consist of 16 sage plantations ($128,682m^2$), 14 shelter-belt plantations ($807,755 m^2$), 17 shore plantations ($447,616m^2$), 10 ornamental plantations ($141,276m^2$) and 6 bower plantations ($79,075 m^2$). Namely, the ratio of shore plantations is highest (n=17) in terms of number, while that of shelter-belt plantations is highest (50.3%) in terms of area. On the other hand, Pinus Thunbergii account for the absolute majority (n=55,239, 74.1 %) of the trees, followed by pine trees (n=18,017, 24.2%). Both species are combined to account for 98.3% of the entire trees, which means that the plantations are simple in terms of tree species When the village groves were compared in terms of functional age, sage plantations are oldest or aged 143 years, followed by bower plantations (aged 137), ornamental plantations (aged 118), shore plantations (aged 92) and shelter-belt plantations (aged 88).

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.

Design of shelter system requires consideration of noise at operators’ positions, because noise can injure person’s health. That is why studies which analyze and predict noise at operator’s positions is essential. To analyze noise sources of shelter system, this study measured noise of each equipment and obtained new equations by comparing the measured noise data and the equation which is relation noise and distance. The new equations predict noise level at operators’ positions. Actran analysis is performed to obtain noise level at operators’ positions too. At last, the noise level at operators’ positions measured in real shelter system is compared with the noise level predicted the new equations and Actran analysis.

This work is focused on a parametric numerical study of the barrier's bar inclination shelter effect in crosswind scenario. The parametric study combines mesh morphing and design of experiments in automated manner. Radial Basis Functions (RBF) method is used for mesh morphing and Ansys Workbench is used as an automation platform. Wind barrier consists of five bars where each bar angle is parameterized. Design points are defined using the design of experiments (DOE) technique to accurately represent the entire design space. Three-dimensional RANS numerical simulation was utilized with commercial software Ansys Fluent 14.5. In addition to the numerical study, experimental measurement of the aerodynamic forces acting on a vehicle is performed in order to define the critical wind disturbance scenario. The wind barrier optimization method combines morphing, an advanced CFD solver, high performance computing, and process automaters. The goal is to present a parametric aerodynamic simulation methodology for the wind barrier shelter that integrates accuracy and an extended design space in an automated manner. In addition, goal driven optimization is conducted for the most influential parameters for the wind barrier shelter.
