본 연구에서는 노지재배 포도의 내한성을 증대시킬 수 있는 방법을 모색하고자 간이비가림시설 설치에 따른 식물체의 반응을 조사하였다. 간이비가림시설에서 월동한 식물체의 탄수화물 함량은 노지 처리구에 비해 높았으며, 'Muscat Bailey A'의 줄기보다 '거봉'과 '캠벨얼리' 품종에서 탄수화물의 함량이 높게 나타났다. 노지에 비해 간이비가림시설에서 발아율과 신초의 생장도 양호하였으나 방충망, 차광막을 처리한 구에서는 유의차가 나타나지 않았다. 포도 잿빛곰팡이병의 발생은 간이비가림시설에서 발생이 적었다. Stilbene 화합물 함량은 노지보다 간이비가림 처리구에서 함량이 약간 더 높게 나타났으며 가장 많이 함유된 stilbene은 배당체 형태인 t-piceid였으며, resveratrol, piceatannol, c-piceid에 비해 상당히 고함량을 나타내었다. Chalcone isomerase, manganese superoxide dismutase, proline rich protein 2, temperature induced lipocalin의 transcripts는 시간이 지날수록 유전자의 발현량이 더 많이 축적되었고, 대체적으로 간이비가림시설의 삽수에서 저온 스트레스에 더 강하게 발현되었다. 처리구별 온도차이는 없었으나 노지에 비해 간이비가림시설에서 풍속이 크게 감소하였으며, 간이비가림시설 내에서 차광막을 설치한 경우 풍속의 감소효과가 현저하게 나타났다. 겨울철의 간이비가림시설과 방충망을 설치함으로써 극저온에 의한 포도나무의 저온피해를 줄일 수 있을 것이다.

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.

Purpose: The purpose of this research was to identify the health behaviors, health status, and utilization patterns of health care institutions for homeless shelter residents as well as to compare these research outcomes between younger and older male homeless shelter residents. Methods: The subjects in this study were 357 homeless shelter residents that were recruited by simple random sampling. Data were collected from August to September 2009. Health behaviors, health status, and utilization patterns of health care institutions were measured using structured questionnaires. Data were analyzed using the Chi square test and Fisher's exact test using SPSS 14.0. Results: Both younger and older male subjects showed unhealthy behaviors, and their health status was lower than that of the Health & Nutrition Examination Survey conducted in 2009. Subjects preferred to utilize national or municipal hospitals as well as pharmacies as opposed to general hospitals, clinics, and public health centers. Conclusion: Differentiated comprehensive health care services and monitoring should be provided to homeless shelter residents based on the needs of each group in order to improve their health status as well as to prevent communicable diseases and complications of chronic diseases.

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.
