This study was conducted to examine the architectural characteristics of Hak-seong Lee Family's Geun-jae-gong Historic House located in Seok-cheon-ri, Ung-chon-myeon, Ulju-gun, Ulsan. The house is said to have been rebuilt in the early 20th century after it was built in the 18th century, and now there are nine buildings left, including the An-chae, Sa-rang-chae, Sa-dang, storehouses and etc. This house is a large-scale house that is difficult to find similar cases in near region. The division of areas on each building is clear, and it is evaluated that it retains the typical characteristics of the head family in the late Joseon Dynasty in terms of its overall size and layout. In addition, the current wooden structure, which is said to have been rebuilt in the early 20th century, shows the composition method and space utilization method of the 3-Dori type upper structure, which have become more diverse since the late Joseon Dynasty. This has not been dealt with in the previous survey, and should be considered in detail through this paper.

In this paper, based on the existing research, we define the parameters for the number of ignition devices to be applied to the pyrovalve, the operation and airtightness according to the temperature, the material of the nipple and the thickness of the fractured part, and ANSYS Ver. 19.2 was used to analyze the FEA model, and a comparative analysis was conducted through structure analysis according to the piston shape of the pyrovalve.

This thesis is a study to Haengnang(行廊, a series of buildings) of Sijeon(市廛, licensed markets), which was built along with palaces, Jongmyo(宗廟) and roads in order to establish Hanyang(漢陽) as the capital of Joseon (朝鮮). Sijeon, built on Jongno and Namdaemun-ro, the main roads in Hanyang, created two-row lands on both sides of the road, and formed Pimat-gil as an inner road between the Jeonbang and Doga. The formation of the city proceeded along with the maintenance of the water path, and the situation of the water path parallel to the flow of Sijeon was achieved. The Sijeon building was a spatial structure managed by independent rooms as a result of reflecting the unique operation method of Sijeon. The Sijeon of Hanyang had an impact on the formation of land, architecture, roads, and waterways, and acted as a major factor in determining the urban spatial structure of Hanyang City.

PURPOSES : The purpose of this study is to investigate the effects of urban road characteristics on temperature changes in urban areas using surface thermal temperature. METHODS : This study measured the surface thermal temperature of each road component from urban roads, analyzed the effect of the road component characteristics and vegetation on temperature, and estimated the regression models. RESULTS : As a result, the mean temperature was 27.3 ℃ on the roadway, 25.5 ℃ on the vegetated median, and 22.9 ℃ on the sidewalks. The roadside temperature was 26.14 ℃ with surrounding buildings and 23.82 ℃ near green spaces. The temperature with street trees was lower (24.45 ℃) than without (28.38 ℃) while it was 23.96 ℃ with vegetated median and 25.64 ℃ without. The temperatures were lower (24.70 ℃) on the permeable surface than on the impermeable surface (28.38 ℃). Model estimates show that the temperature decreases by 0.007 ℃ with an increase of 1 m² green (permeable space) space and the temperature with buildings tends to be 1.729 ℃ higher than that with green space. As green space increases by 1 m², the temperature tends to decrease by 0.017 ℃ on the roadway and by 0.012 ℃ on the sidewalk. Shade effect models show that street trees with shade affect temperature reduction by -3.884 ℃ on roadways and -3.314 ℃ on sidewalks. CONCLUSIONS : The results of this study demonstrate the differing effects of road characteristics on temperature. The roadway is more sensitive than the sidewalk to temperature changes and roadside vegetation, ambient green space, and pavement permeability contribute to temperature reduction.

본 연구에서는 아파트단지 내 불량한 식생공간을 보수하거나 다양한 식생으로의 재조성하여 녹색의 질을 높이기 위한 방안으로 아파트 단지 내 조경관리 현황을 조사하고 식재지반인 토양상태를 파악하여 합리적인 계획 수립을 위한 기초 자료화 하는 것을 목적으로 하였다. 아파트 준공시점을 기준으로 동일한 규격의 수목이 동시에 식재되는 것을 감안해 준공연도를 5년 단위로 구분하고 식재기간 경과에 따른 수목생장과 토양성분의 차이를 분석하였다. 전체 조사대상지 9개소에 모두 식재된 수종 중 침엽수 4종과 활엽수 4종의 생육상태를 조사하여 한 결과 침엽수 중 가이즈까향나무 소나무, 활엽수 중에서는 꽃사과나무가 5년 이상의 식재기간이 경과되었을 때 가장 생육이 좋았다가 10년 이상 되었을 때는 생장이 감소하였다. 측백나무와 단풍나무는 10년 이상 된 지역의 수목이 생육이 가장 좋아 비교적 생장을 위한 기간이 많이 요구되는 수종이었다. 수목은 식재되어 있으나 지표면이 나지가 되어있는 지점의 토양경도를 분석한 결과 준공 후 5년 이상이 되면 20㎜ 이상의 답압 된 상태가 되는 것으로 조사되었고 토양이화학성은 준공 초기부터 지속적으로 pH는 높고 유기물함량은 비옥한 토양의 1/3 정도로 추가 시비가 필요한 상태였다. 본 결과를 토대로 나지부분의 재식재시에는 식재지 주변 배수로 설계와 토심 50㎝ 정도를 객토하고 왕겨 등의 유기질재료를 혼합하는 정도의 토양 개량 계획을 추가하여 수목 하부에 지피식물을 식재하는 것만으로 토양의 답압과 토양건강성을 회복하는 방안이 될 것이라고 사료된다.

게임 공간에서 플레이어는 시공간적 한계가 없는 활동 영역과 다중적이고 변화하는 자아상을 체험한다. 게임 속 가상공간은 무수한 다시점과 움직이는 시선을 가진다는 점과 온 몸의 체험을 통해 대상을 관조한다는 점에서 동아시아의 전통회화와 공통점을 가진다. 플레이어는 게임 공간 밖의 물리적 자아와 게임 공간 안에서 현전하는 자아로 분열되며 그 둘은 서로 상호 작용과 반작용의 행위로 연결된다. 이 때 게임 플레이어의 표현은 수동적 지각의 경험이 아니라 게임의 내용을 완성하고 다양한 층위의 의미 해석을 가능하게 하는 적극적 활동이며 현전적 자아의 체험을 지금여기로 소환하는 행위이다. 또한 게임 플레이어의 행동은 반복이라는 일정한 패턴을 가진다. 어린아이의 놀이에서와 같이 플레이어는 상호작용적 반복 행위를 통해 자아를 표현하고 게임 세계를 창조해 나간다. 여기서 반복행위는 상실과 불안을 벗어나 건강한 상태를 유지하려는 회복의 욕구를 반영하고 자기애를 실현하는 실존적 자아를 형성하는 행위로 정의된다. 따라서 게임공간은 자아의 확장과 표현을 통해 건강한 자기애를 실현할 수 있는 적극적인 예술표현과 치료의 장이다.

There is growing interest in the various functions of urban green spaces that can improve urban resilience. Urban green spaces have an important role in wildlife habitat, climate and hydrological control, and recreation and outdoor activities. The connectivity of a green space network is known to control urban resilience by minimizing the disturbance caused by urbanization and climate change and strengthening the adaptation capacity. In this study, we analyzed the social-ecological network characteristics of green space in the city of Jeonju, South Korea. To analyze the ecological network, we defined wildlife habitat as the ecological node and used an index based on graph theory. We defined residential area as the social node, and we analyzed the accessibility of green space from the residential area to assess the social network. The results indicate that the green spaces in Jeonju are highly connected in the social and ecological perspectives on the fringe of the city. However, our founding also indicated that the social and ecological connectivity of the green space network in the downtown area should be improved. This study can be used as a basis for establishing an Urban Open Space Conservation Plan that considers the improvement of urban resilience in the future.

소비자들의 구매 욕구를 충족시키기 위하여 상업시설에서는 판매와 관련된 다양한 공간표현이 요구되고, 소비자의 시선을 끄는 상품의 배치나 공간구성은 곧 마케팅 전략으로 이어질 수 있다. 사람의 눈은 가장 많은 정보를 획득하는 감각기관으로 시각정보에 대한 분석은 <공간과 사용자>의 상호간의 시각적 관련성을 파악할 수 있는데, 그간 연구에서는 실험이미지를 통해 정지된 화상에 대한 분석이 대다수 이며, 상업공간의 이동영상을 바탕으로 공간에 대한 시선정보를 분석한 연구는 미비하다. 이에 본 연구에서는 상업시설의 이동경로를 촬영한 동영상을 실험에 사용함으로써 공간분석에 있어 사실감이 부여된 공간 사용자 시선정보를 통한 감성반응을 분석하였다. 이동동선의 직선구간을 분석구간으로 설정하고, 획득된 데이터를 바탕으로 5개의 주시강도 범위에 대한 구간특성을 살펴본 결과, 이동동선의 시작점인 A구간(직선구간-1)에서는 주시강도가 낮게 나타났으며, B구간(직선구간-2)에서 가장 높은 주시강도가 나타난 것을 알 수 있다. 이는 피험자들의 B구간부터 안정적인 공간 탐색을 한 것으로 볼 수 있으며, 실험영상에 대한 적응시간이 필요한 것을 알 수 있다. 주시집중구역에 대한 공간특성을 살펴보면, 6개 구간 중 4개 구간에서 우측매장의 진열방식에 대한 시선의 집중이 더 높게 나타난 것을 알 수 있다. 소비자의 시선이 높게 머무른 요소는 소품위주로 시선이 유도되었으며, 매장 내 쇼케이스 같은 진열형식에 시선정보가 높게 나타난 것을 알 수 있다. 이러한 분석방법을 통해 소비자의 시선이 선호하는 상품진열방법, 상품요소 배치 등 직접적인 디자인 자료로 활용 가치가 높게 제공 될 수 있을 것으로 사료된다.

Mugiyeondang(舞沂蓮塘) is the garden that the provincial noble family in Yeongnam(嶺南) has constructed since the late Joseon period. Mugiyeondang is well known as a typical case of traditional garden in Joseon period. But it is also an exceptional case because of its informal layout that infers gradual space transition. This study aims to establish the historical story of the garden beyond the superficial description about existing spatial status and literature materials. Mugiyeondang had been constructed by seven generations of the family during two hundred years, and there were significant events at every transition points. The figure and name of elements reflects each historical change of the family. Mugiyeondang is an important case to notice that a garden was not just a subsidiary space for mere leisure life of the gentry of Joseon period, But it was an important for some families as their representative and symbolic space.

Senior citizens are reported to be highly sensitive to environmental pollutants, including fine particulate matter. The purpose of this study is to investigate the distributions of fine particulate matter concentrations in town halls and senior citizens’ halls, where senior citizens typically spend a lot of time. The results of this investigation will serve as fundamental data for conducting indoor air quality studies and establishing a regional environmental health policy governing senior citizens’ facilities in Yeongwol county in the future. From January 4 to February 1, 2017, PM10 and PM2.5 concentrations in 170 seniors’ facilities located in Yeongwol county were measured. The average concentrations of PM10 and PM2.5 that were measured from each seniors’ facility chosen from Yeongwol county were 25.1 ± 18.9 μg/m3and 12.5 ± 9.3 μg/m3 respectively. Average concentrations and the average of maximum concentrations were lower than the living space standard of 100 μg/m3 for PM10 and the atmospheric environment standard of 50 μg/m3 for PM2.5, which were set by the Ministry of Environment for populations vulnerable to environmental pollution. As a result of analyzing the sources in seniors’ facilities in Yeongwol county during the winter months, it was found that indoor sources of air pollution such as cooking is main sources rather than outdoor sources of air pollution.

The purpose of this study is to investigate the space composition and landscape structure around the village forests in five villages located on the coast of Wando-gun. The research focuses on field investigation and literature review. The results of this study are as follows In the case of village forests constructed for the protection of villages and cultivated areas in the coastal area of Wando-gun, which is the study area, it is confirmed that there are mountains behind the forests. Through the analysis of landscape elements, it was concluded that two types of layouts exist. Regarding the space composition around the village forest on the coast, it was found that there is a type A arranged in the order of sea → coast → village forest → village → cultivated land → rear mountain, and a type B arranged in the order the sea → coast → village forest → cultivated land → village → cultivated land → rear mountain. In the analysis of landscape characteristics, the elevation angle from the coast to the top of the mountain behind the village forest was measured. Accordingly, elevation angles of approximately 16°–17° in the type A arrangement and 7°–9° in type B arrangement were determined. From these results, it can be confirmed that the space composition and placement of the village forest with disaster prevention function vary according to the distance and elevation (changes in elevation angle) from the coast to the rear mountain.

The buffer green space of Sihwa industrial complex is located on the boundary of residential areas and industrial areas, and this regions have been the ability to mitigate environmental impact of noise, vibration, atmospheric. In this area, the survey of vegetation and bird was conducted to understand the biology structures and function of buffer green space from biology habitats and natural recovery for ecology restoration. The survey was performed four times according to the season.

Thus, as providing safe habitats and movement passageway of wildlife, the connection of ecological green areas will be strengthened.

농장동물복지형 한우 사양관리를 통한 고품질의 쇠고기 생산을 목표로 세계적인 트랜드에 부합하는 축산선진국으로 나아가기 위하여 본 시험으로 우방내 사육공간의 넓이차이에 따른 한우의 사양성적, 행 동특성 및 혈액성상에 미치는 영향을 비교·분석해 보았다. 16개월령의 한우 54두(암소 미경산공태우 및 거세우 각각 27두)를 공시하여 성별에 따라 사육공간의 넓이차이를 주기 위해 4두(8m2), 3두 (10.67m2) 및 2두(16m2)로 처리하여 9개월간 각각 3반복으로 완전 임의배치 후 실시하였으며, 한우 사 양관리 프로그램에 따라 사료급여를 하였다. 데이터 수집방법으로 증체량, 사료요구율 및 혈액분석은 2 개월 간격으로 반복하여 측정하였으며, 행동패턴 수집은 복수개체 추적방법 및 선택적 행동관찰법으로 기상청에서 제공한 맑은 날을 선정하여 15일간 녹화 후 분석에 이용하였다. 본 시험의 결과로, 사양성 적(체중, 일당증체량 및 사료요구율)의 경우 미경산공태우와 거세우 각각 20개월령과 18개월령 이후부 터 2두와 3두 처리구에서 모두 유의적(p<0.05)으로 향상되었다. 행동특성으로는 미경산공태우의 2두 처 리구에서 행동시간으로 기립행동은 유의적(p<0.05)으로 낮고, 횡와 및 걷기행동은 유의적(p<0.05)으로 높았다. 행동빈도에서는 음수, 자기몸핥기, 긁기, 몸비비기, 투쟁행동에서 유의적(p<0.05)으로 적게 나 타났다. 거세우의 2두 및 3두 처리구에서는 미경산공태우와 유사한 경향을 나타냈으나 유의적(p<0.05) 으로 섭식시간은 증가하고, 다른소핥기 및 몸기대기의 빈도는 유의적(p<0.05)으로 적게 나타났다. 혈액 성상으로 미경산공태우와 거세우의 4두 처리구에서 적혈구가 유의적(p<0.05)으로 낮았고, 콜티졸은 유 의적(p<0.05)으로 높게 나타났다. 또한, 미경산공태우의 헤모글로빈과 거세우의 백혈구 수치에서는 모 두 2두 처리구에서 유의적(p<0.05)으로 각각 높고 낮은 것으로 분석되었다. 이상의 결과를 종합하면 사 양성적, 행동특성 및 혈액성상 등의 전체적인 내용을 토대로 우사의 여유 및 표준우사의 우방크기를 고 려할 때 한우의 사육공간에서 관행사육인 4두 처리구(두당 8m2) 보다 미경산공태우는 2두 처리구(두당 16m2), 거세우는 3두 처리구(두당 10.67m2)로 사육하는 것이 적절하다고 판단되며, 본 시험결과는 추후 복지형 한우의 사양관리를 위한 기초자료로 활용할 수 있을 것으로 판단된다.

The aim of this study was to investigate the effects of different rearing spaces on growth performances, behavioral traits, and blood parameters in Hanwoo (Korean Native Cattle) heifers and steers. The average daily gain and feed conversion ratio were measured to assess the growth performance. A total of 54 Hanwoo heifers and steers at 18 months old, were housed separately in groups of 2, 3 or 4 heads in a pen (32 m2) for nine months. In the case of the heifers, the growth performances were significantly (p<0.05) improved by increasing the 2 head group size with the exception of the 18 month old heifers. However, among the steers the growth performances were significantly enhanced (p<0.05) after 18 months of age, by increasing the 3 heads group size. In addition, the heifers in groups of 2 heads spent less time standing and more time lying down or walking, and also had a significantly (p<0.05) lower frequency of self-grooming, scratching, and fighting. These findings are similar to the results obtained for steers housed in 2 or 3 heads per group. The steers housed in 2, 3 heads groups spent more time feeding and consequently had a significantly (p<0.05) lower frequency of pair-wise grooming and Leaning. The heifers and steers housed in groups of 4 heads showed lowest red blood cell counts, but highest cortisol content with statistical significance at p<0.05. The heifers in groups of 2 heads had the highest hemoglobin concentrations (p<0.05). On the other hand, white blood cell count was found to be the lowest in groups of 2 steers with statistical significance at p<0.05. We conclude that a large rearing space improved growth performances, behavioral characteristics, and blood parameters in Hanwoo heifers and steers. In the future, this data could be used to improve the welfare of rearing Hanwoo cattle.

This research was conducted to compare and analyze the effect of the space allowance on the productivity, behavior, and blood properties of Hanwoo in order to achieve the status of advanced country for the animal husbandry in accordance with global trends, and with the target of animal welfare production through the practice of environmentally friendly animal husbandry. Fattening cows (352kg) of an average of 43 months in age and with growing steers (225kg) aged six months were tested with two replications upon categorizing the animals into control group (8m2/heads) and treatment group (4m2/heads). Feeding was executed according to the prescription in the Hanwoo feeding management. The growth performances (BW, ADG, and FCR) were significantly improved in cow fattening as space allowance was narrower. Similar results were obtained from the growing steers. The behavioral characteristics of lying and walking were significantly higher in the control group (p<0.05), while standing was found significantly higher (p<0.01) in the treatment group. The lying duration did not show significant difference in the fattening cows. Meanwhile, walking time was significantly longer (p<0.01) in the control group among fattening cows whereas standing duration was significantly higher (p<0.05) in the treatment group. As for properties of blood component, the cortisol value was significantly higher (p<0.05) in the treatment group for the fattened cows. The experiment results imply that the space of 8 m2 / head would be adequate in the production of fattening cows and growing steers based on growth performances, behavioral characteristics, and blood component, and considering the space allowance per head in the pen. The results could be utilized as basic data for environmentally friendly and welfare type Hanwoo production system in the future.

모드분해법은 해석의 효율성, 동적특성 추정 등에 매우 유용한 도구로 사용되어 왔다. 그러나 댐퍼와 같은 진동제어시스템이 설치된 비고전감쇠 구조물에 대해서 기존의 모드분리법에 의해서 분리가 잘 이루어지진 않는다. 본 연구에서는 비고전 감쇠를 가지는 구조물의 운동방정식을 상태방정식으로 변환한 후 상태공간에서 모드분해하는 기법을 제안하고 상태공간 모드분해 기법에 의해 분리 된 모드응답의 특성을 다루었다. 제안방법의 검증과 모드응답특성을 분석하기 위하여 비고전감쇠를 가지는 3자유도 구조물에 대한 수치시뮬레이션을 수행하였다. 수치해석 결과, 고전감쇠 구조물에 대한 상태공간 모드행렬의 대각블럭 행렬은 기존의 모드행렬과 같으며, 대각외 블록행렬은 모두 ‘0’의 값을 가지는 것으로 나타났다. 비고전 감쇠 구조물에 대한 상태공간 모드행렬은 대각외 블록의 행렬 도 값을 가지는 것으로 나타났으며, 그 값은 대각블럭 행렬에 비하여 매우 작은 것을 알 수 있었다. 또한 계측응답만을 이용하여 상태 공간에서 모드분리가 가능한 것으로 나타났으며, 동일한 고유진동수를 가지는 모드응답은 상호간 변위-속도관계를 가지도록 분해 가능함을 보였다.
