This study is the conditions of location according to formed the times in the clan village. The results of this study are as follows ; 1. in the 15th century, the characterestics of the village established residencial place where mountain stream flowed surrounded by the mountain and deep in the mountains with superior quality land. That's because Sa-dae-bu put equal importance on beautiful scenery and practical benefit for living. Stream House provided economical foundation for Sa-dae-bu to be able to keep confucial manners by putting limit their economic status to small medium sized land owner. Topographical condition such as valley or hollow separated from the exterior maintained unification of consanguineous village in self sufficient farming society and held on to independent territory against external to be able to stay away from turbulent days so that they formed residential area of Sa-dae-bu clan. And the valley where flowed clean water was considered as the connection of continuous place where distinctiveness of form in each curve and and factor of calm and dynamic scenery of the clean stream. Scholars in the middle of Chosun Dynasty located in the utopia as place for confucious retirement to study, a place for refinement by combination with the nature or as a way of spacial practice based on Confucious view of nature. 2. in the 16th-l7th century, Most of existing consanguineous villages adopt deep in the mountains for refuge. at that place, upward rank was established by settlement of the ancestor who entered in the village first, the principal was placed in the center of the village and since descendants became numerous, it was serialized as the space of descendants. So, it was arranged in the order of social rank. Most of the villages showed development step by step started from precaution by apperance of the mountain to the lower part. It's because the topography of valley around the village worked as the natural hedge against external force and genealogy of the clan, regularity of social status, order of entrance into the village were reflected into residencial destribution. Also, order of the rank coincided with the one of aspects on geomancy. Genealogical rank within the village represented spacial rank. Houses of descendants and branch families were placed lower than the principal which showed worship to the principal. 3. In 18th century after, as the village was settled nearby cultivated land considering economical loss caused by long distance between residencial area and cultivated land, direction of sect followed by development of village expanded from the front part of the village to the rear part. The principal that was poped out to the front presented frontage over exterior. Therefore, residencial area of branch families expanded to the rear starting from the principal. This represented a slice of social structure at that time. after 18th century, spirit was percieved superior over material, After then, development of cultivation and expantion of land created difference of economic strength within one village. In order to maintain and show off the status of Yang-ban, economic power of indigenous land owner became fundamental, so, sense to worship and to keep the principal became weak eventually. Taking advantage of that situation, residencial area of branch family expanded to the rear part of the principal which showed dual disposition conflicted with each other. However, these clan rules were destroyed and new rules were created after 18th century because of the situation and consciousness at that time.

What is the meaning of home to older people? How much is home significant for older people? How do they express self-identity through decorating their own homes? These are the new subjects that scholars in the West are involved in lately in terms of micro-perspective (George, 1998; Kellett, Gilroy & Jason, 2005; Gilroy & Kellett, 2006). It is evident that home has more significant meaning to older people than other age groups, since the older are more likely to spend greater time within the home through lower income, lessening mobility or loss of companions (Gilroy, 2005). Also the older tend to cling to their homes and attach to possessions than the younger. Older people's possessions are the things that memories of their lives were absorbed. Therefore, possession display can role as a mean of showing their past lives and memories. Gilroy and her colleagues (2005, 2006) found that there was a certain pattern of possession display in English older people's households, and that older people would like to express self-identity through decorating their own homes with their precious possessions. Then, isn't it interesting to find out if there is any pattern of possession display or decoration items in Korean older people's households as well? Thus, the aim of this study is to describe pattern of possession display as a mean of expressing self-identity in Korean older people's households. Interview with older people was used to find out the way and reason of display possessions. Observation method including taking photos and hand-drawings was also added in order to demonstrate detail condition of display items in the house. Possessions display and furniture arrangement in the living room and bedroom were investigated to find out a certain pattern of display and meaning. Research objects were healthy older people aged over 60, who are living independently from their adult children, and who can manage housekeeping by themselves. 32 households were investigated in the area of Seoul, Kyunggi, Chungchungnam, and Kangwon provinces. The findings demonstrate that most precious possession for Korean older people is photo of themselves; especially one taken in their younger age. The reason of it is because the photo reminds them of their heydays when they were vital. Photo of the most beloved one is displayed more frequently in the bedroom than in the living room indicating consistence with English case. As symmetrical display pattern was dominant in case of English older people's households, no dominant display pattern is found in Korean case. Korean older people also cling to their homes and possessions and want to keep their dwelling space as large as what they use now. It is notable that even after they become older and frail, they want sufficient space to display possessions as a mean of self-identity expression. Attachment to possessions and decoration can give older people significant meaning of identity, and it is the reason why architects or interior designers have to meet older people's needs. It needs consideration that residents are allowed to bring their old furniture and precious possessions when they move in elderly housing unit in order to minimize environmental shock, as well as feeling at home. This subject could suggest a clue to designers or architects who have to meet residents' needs in space design of elderly housing or facilities in the future. Psychological well-being of older people can be met by making them feel at home wherever they live. They need space where they can express their own identity and personality even in case when they have to live in a limited small space like elderly housing unit or nursing home.

Despite the public health importance of injury and poisoning in terms of its high mortality and incidence, epidemiologic information to be utilized are scarce in Korea. This study was carried out in 1990 on a representative sample population (about 55,000 persons) along with the 6th National Tuberculosis Prevalence Survey in order to estimate the magnitude of injury and poisoning occurrence and to identify its epidemiologic characteristics which can be aided for establishing preventive strategy. Pre-tested and structured Questionnaire was used by trained interviewer to collect data including general information of the person, various information on the injury and poisoning during the past one year such as time and place of its occurrence, its nature and external causes, type of medical institute attended, duration of treatment and outcome of the accident occured. In analysis of the data collected incidence rates per 1000 persons by sex, age group and its nature as well as external causes, and relative frequencies were calculated. The result obtained are as followings; 1. The incidence rate per 1000 was 30 for both sexes, 39 for male and 22 for female, male being 1.8 times more frequent than female. Age adjusted incidences were not much different from the crude rates. Age group specific rate curve showed bimodal shape in both sexes, small peaks in preschool children and higher peaks in older ages. The incidence rate per 1000 people by area was highest in Jeon-bug province (57/1000) and the lowest in Daegu city(11/1000). 2. The place where the injuries occured were road in 46%, within the boundary of house in 25%, and working place in 12% The injuries and poisoning had occured more frequently during the months from March to August of the year than other months. 3. The relatively frequent injuries by its nature were contusion with intact skin surface (19%), fracture of upper limb (13%), open wound of head, neck and trunk (12%) and fracture of lower limb (11%) among males; contusion with intact skin surface (28%), sprains and strains of joints and adjacent muscle (14%), fracture of upper limb (10%) and fracture of lower limb (9%) among females. Higher incidence rate among males than females were fracture of skull (4.5 times), open wound and fractures of limbs ($2{\sim}3$ times). Age specific rate of injuries and poisoning by its nature showed increasing pattern by age in fractures of upper and lower limbs and sprains & strains of joints whereas the age group of 30's showed highest incidence in open wounds of upper limb. Fractures of radius and ulna in upper limb, fractures of tibia & fibula and ankle in lower limb were most frequent among fractures of upper and lower limbs. The frequent injuries among sprains and strains of joints and adjacent muscles were that of ankle, foot and back, and among open wound were that of head and fingers. 4. Relative frequency of injuries and poisoning by external causes showed following order : other accidents (25%), accidental falls (23%), motor vehicle accident (22%) and other road vehicle accident (14%) among males and accidental falls (37%), motor vehicle accident (24%) and other accident (18%) among females. The external causes revealing higher incidences among males than females, were other road vehicle accident (4.8 times), vehicle accident not elsewhere classifiable (4.4 times), accidental poisoning (4.4 times), accidents due to natural and environmental factors (2.8 times), and sucide & self-inflicted injuries (2.8 times). Age specific incidence by external causes for frequent injuries showed that incidence of other accident steadily increased from 10's till age 50's; motor vehicle traffic accident increased from age 20's and dropped after age 60's; on the other hand accidental fall increased strikingly by age. The most frequent external causes among motor vehicle traffic accidents was motor vehicle traffic accident involving collision with pedstrain (69%), pedal cycle accident (30%) and other road vehicle accident (71%) among other road vehicle accidents; falls on same level from slipping, tripping or standing (44%) and other falls from one level to another among accidental falls; accidents caused by machinary (32%) for male and striking against or struck accidentally by objects or person for female among other accidents. 5. Seventy nine percent of the injuries and poisonings were treated in general hospital or hospital/clinic. The duration of treatment ranged from a few days to 123 weeks; the majority(52%) took under 2 weeks, 36% for $3{\sim}8$ weeks and 4% over 21 weeks. 6. The accident resulted in full recovery of normal healthy state in 62%, residual functional defects in 21% and on process of treatment in 16%.

Authors are trying to unveil the ultrastructural organization of olfactory bulb, which has been summerized under light microscopic level or communicated only in some detail in different view point until now. For the critical point of view, since the phylogenetical approach will give the ultimate value in the correlative study between structural and functional bases (Brodal, 1969), the present study was carried out light and electron microscopic analyses of the structures of the neurons and synaptic organizations in olfactory bulbs from different animals in phylogenetical scale. We selected each one species from five animal classes: the house rabbit(Oryctolagus cuniculus var. domesticus [Gmelin]) from Mammalia, the domestic fowl (Gallus gallus domesticus Brisson) from Aves, the viper (Agkistrodon hylys [G.P. Pallas]) from Reptilia, a frog (Bombiana orientalis Boulenger) from Amphibia and the crussian carp (Carassius carassius [Linne]) from Pisces. For light microscopic study, samples were fixed in 10% formalin and paraffin sections were stained with hematoxylin-eosin. For the electron microscopic study, the tissues were fixed by perfusion through the heart or immersion with 1% paraform-aldehyde-glutaraldehyde mixture (phosphate buffer, pH 7.4), and final tissue block trimmed under dissecting microscope were osmicated (1% OsO4), they were embedded in Araldite or Epon 812, and ultrathin sections were made by LKB-V ultratome following the inspection of semi-thin sections stained with toluidine blue-borax solution. Ultra-thin sections contrasted with uranyl acetate and lead citrate were observed with JEM 100CX electron microscope. We have summerized our morphological analyses as follows: 1. The olfactory bulb of rabbit, viper and frog shows the eight layers of fila olfactoria, glomerular, external granular, external plexiform, mitral cell, internal plexiform, internal granular, medullary but domestic fowl shows the five layers of glomerular, fibrillar, mitral, granular and medullary and the three layers of fibrilla, glomerular and medullary in crussian carp. The sharpness of demarcation between the layers shows deferential tendency according to phylogenetical order. 2. Mitral cells of vertebrate have large triangular or oval shape with spherical nuclei which contain not so much chromatin. The cytoplasm contains numerous cell organelles, of which Nissl's bodies or granular endoplasmic reticula arranged as parallel strands. Development of granular endoplasmic reticula were declined as the phylogentical grade is going lower. 3. Tufted cells of all animal are mostly spindle or polygonal contour and contain oval nuclei which located in periphery of cytoplasm. The nuclei of rabbit, fowl, viper and frog has relatively space chromatin, but a nucleus of crussian carp contain irregularly aggregated chromatin in karyoplasm. Their cytoplasmic volume and cell organelle contents are in between those of mitral cell and granular cell. They contain moderate amount of mitochondria, granular endoplasmic reticula, a few Golgi complex, polysomes, lysosome, etc. 4. Granule of cells of all the vertebrate amimals studied exhibit similar features; cells and their dense nuclei show spherical or oval contour, and they have the thin rim of cytoplasm which contain only a few cell organelles. 5. In rabbit, the soma of mitral cells were in contact with boutons with two types of synaptic vesicles, that is, round and flat vesicles, especially flat vesicles in boutons were showing reciprocal synapses. However, in domestic fowls, vipers, frogs and crussian carps, there were found boutons showing only spherical synaptic vesicles. 6. The boutons containing round synaptic vesicles were made contact with the some of tufted cell of olfactory bulb in the rabbits, fowls, vipers and frogs, but no synaptic boutons were observed in soma of tufted cells in crussian carps. In the frogs, there were observed dendrites were contact with the soma of tufted cells. 7. In the neuropils of plexiform, granular and glomerular layers olfactory bulbs in the vertebrate, the synapses were axo-large dendrites, axo-median and small dendrites, dendrodendritic, and axo-axonal contacts. However, in the neuropil of crussian carps, synapses were observed only in glomerular layer.

수분조건(${\theta}$m 0.2, 0.3, 0.4, 0.5) 변화에 따른 토양내 우분퇴비의 질소와 탄소의 전환특성을 조사하기 위해 7월말에서 11월 초 사이 15주간 실내에서 Incubation 실험을 실시하였다. 실험기간동안에 토양 pH는 질산화 과정중 발생되는 수소의 영향으로 낮은 폭으로 지속적인 감소를 보였으며, 유기물과 수분처리량이 증가할수록 암모니아 질소의 발생률의 증대와 환원물질의 생성으로 토양 pH가 높아졌다. 전 질소의 감소율은 수분량이 증가할수록 증가하는 경향을 보였으나, 전 탄소는 이와 반대의 경향을 보였다. 따라서 낮은 수분조건(${\theta}$m 0.2)에서 C/N율은 시험기간동안 지속적으로 감소되어 지력이 증진됨을 볼 수 있었으나, ${\theta}$m 0.4 이상의 높은 수분조건에서는 지속적인 C/N율 증가가 발생되어 지력 감소와 토양 pH 감소 원인으로 작용하였다. 우분처리에 따른 $NO_3\;^--N$ 발생량은 ${\theta}$m 0.3 이하의 수분조건에서는 비교적 양호한 통기조건 때문에 지속적으로 증가되었으나, ${\theta}$m 0.4 이상의 조건에서는 초기에 큰 폭의 감소가 발생되었으며, 특히 ${\theta}$m 0.5에서는 2∼3주 이후 $NO_3\;^--N$가 발생되지 않았다. 그러나 $NH_4\;^+-N$의 발생량은 위와 반대경향을 보여, 수분함량이 증가함에 따라 발생량이 증대되는 경향을 보였다. 전 질소에 대한 무기태 질소의 비율로 나타낸 질소의 무기화율은 낮은 수분조건에서는 꾸준히 증가하였으나, 높은 수분조건에서는 초기 큰 폭의 감소가 발생된 후 서서히 증가되는 경향을 보였다. 이상의 결과를 종합할 때, 토양내 유기물 시용시 지력 유지 측면에서 토양내 수분조건은 대단히 중요하며, 높은 수분조건에서는 질소 손실량 증대에 의한 지력 감소가 발생될 것으로 예측되었다.${\theta}$ m 0.2 정도의 적정 수분조건에서는 양호한 통기성과 수분유지로 인한 질소 손실을 줄일 수 있었다.

시설보안은 항상 보안영역에서 가장 중요한 부분을 차지하고 있다. 일반적으로 통합적 보안계획은 세 가지 요소로 구성된다. 여기에는 시설보안, 인사보안, 정보보안이 포함된다. 이 세 가지 요소는 상호간에 긴밀하게 연계되어 있고 보호하고자 하는 대상 시설과 기업의 유형에 따라 매우 다양하게 운영된다. 통합보안프로그램에서 시설보안요스는 대체적으로 정책과 절차, 사람, 방벽, 장비와 기록물로 구성된다. 인간은 선사시대부터 자신과 부족의 생명을 보존하기 위하여 쉼 없는 투쟁을 계속하였다. 그러나 선사시대의 인간들은 어떻게 견고한 집을 짓고 거주지를 어떻게 요새화하는지를 배우지 못하였기 때문에 자신들의 보호를 자연에 의존하였고 추운 날씨에는 동굴들을 보호나 피난처로 활용하였다. 인류사를 통하여 인간은 자신과 자신이 속한 부족의 생명과 자산을 보호하기 위하여 다양한 보호대책을 수립하여 왔다. 이러한 보안대책의 기본에는 시설보안대책이 자리하고 있다. 중세시대의 유럽의 대군주들은 성곽 둘레를 파내어 해자를 건설하거나 도개교를 만들어서 성 주위를 강화하고 거주자들에게 이러한 보호를 제공하고 경작된 농산물을 제공받았다. 20세기 들어 미국의 에드윈 홈즈는 미국의 보안산업발전에 혁신적인 전자경보서비스를 제공하기 시작하였다. 이것이 오늘날 전자보안시스템의 효시이며, 발전을 거듭하여 오늘날 해당 시설물에 다양한 전자보안시스템을 조합한 형태의 보안시스템이 보안시장의 대부분을 차지하고 있다. 이와 같이 인류는 태초부터 생명을 보호하기 위한 방법으로 다양한 보호대책을 수립하여 발전을 계속하고 있다. 오늘날 현대인은 생명과 자산의 보호와 다양한 사회병리현상에 대응하기 위하여 전국 방방곡곡 대부분의 시설물에 CCTV가 설치되어 현대인의 일상을 보호 감시하고 있다. 이러한 대부분의 시설보안시스템은 우리의 안전을 보장하기 위하여 설치되고 있으나 이에 대한 모든 비용 또한 우리가 지불하여야 한다. 따라서 효과적인 시설보안시스템의 구축은 매우 중요한 당면 과제이다. 이 연구에서는 현대사회의 필요성에 의해서 급속하게 증가하고 있는 시설보안시스템의 효과적인 구축방안에 대하여 보안디자인의 원리에 시스템 통합을 활용하여 효과적인 시설보안시스템 구축방안에 대하여 제시하였다.

쌍산재는 1800년대 중반에 조성된 민가 정원이다. 북으로 지리산 줄기를 등지고 남으로는 섬진강을 내려다보는, 전형적인 한국의 배산임수 형국을 이루는 터에 입지하고 있다. 조성된 이후 6대를 거쳐 오면서도 정원에 큰 변화 없이 조선 후기 민가 정원의 면모를 잘 간직하고 있는 정원이다. 본 연구는 현장 조사와 인터뷰, 작정자의 유고집과 편액, 주련의 내용 분석을 통해 역사 정원으로서 쌍산재의 변화하는 경관에 대해 고찰하였다. 완만한 구릉지에 위치한 쌍산재는 크게 내원과 외원으로 분류되며, 내원은 진입 공간, 주거 공간, 전이 공간, 후원 영역으로 구분된다. 후원은 서당채와 그 정원, 경암당 등으로 구성되며 외원인 사도저수지 영역으로 이어 진다. 쌍산재의 특징적인 식생 경관은 13,000m²의 죽녹차밭과 잔디밭을 가로지르는 길 양쪽에 열식된 모란과 작약, 그리고 동백이나 사철나무의 휜 가지가 보여주는 액경, 마지막으로 탱자나무와 대나무로 이뤄진 생울타리를 꼽을 수 있다. 쌍산재는 지형과 원식생(原植生)을 고려한 공간 구성과 배치가 돋보인다. 주요 건축물은 후손들이 선대의 아호를 따 이름 지었는데, 벼슬길에 오르지 않고, 은일하며 후학을 양성하고자 했던 선대 조영자들의 철학관이 묻어난다. 오주석 선생이 세운 입석과 하얀 경계석은 쌍산재만의 독특한 정원 시설이다. 현 소유자가 가족들과 방문객의 편의를 위해 조성한 석상, 돌의자, 수영장 등 또한 특징적인 경관을 연출한다. 쌍산재는 거주자에게는 살림집이자 친우들과의 교류의 장, 수신(修身)과 은일(隱逸)의 장이었으며, 아이들에게는 배움의 장이었다면 현재는 여러 사람들이 힐링할 수 있는 민가 정원으로서 성격을 갖는다. 200여 년의 시간이 흐르는 동안 쌍산재의 내외원의 경관은 일부 변화를 겪었다. 이렇듯 변화하는 속성을 가진 역사 정원의 특성은 살아 있는 유산으로서 정원 고유의 속성으로 인식할 필요가 있다. 본 연구는 쌍산재를 조경학 관점에서 다룬 최초의 연구로서, 현존하는 조선조 민가 정원이 매우 적다는 점에서 앞으로 보다 심층적인 연구가 필요할 것으로 본다. 아울러 현재 점차 관심이 높아지고 있는 정원 관광 상품으로서 역사 정원의 가치와 효용을 가늠해 볼 여지도 있을 것으로 판단된다.

기후변화로 인한 이상기온 현상으로 전 세계적으로 자연재해와 피해가 점차 증가하고 있다. 이는 저온성작물로 알려진 감자 생산에 악영향을 미칠 것으로 예상된다. 향후 식량안보작물로서의 감자의 역할은 증대될 것으로 예상되지만, 감자에 대한 기후변화의 영향과 대응책은 충분히 확립되어 있지 않다. 따라서 본 연구를 통해 폭염처리에 따른 감자의 피해 양상을 분석하고, 품종별 반응을 평가하여 이상고온 환경에 대응하는 감자의 안정 재배기술을 확립하고자 수행하였다. 폭염처리(35~37℃)는 한여름(7월) 비닐하우스를 밀폐하여 처리하였으며, 대조구와 비교하여 감자의 수량 및 품질 특성을 비교하였다. 폭염처리를 했을 때 총 수량과 상서수량 및 주당 괴경수는 감소하는 것으로 나타났다. 폭염처리 시 자영 품종은 대조구에 비해 상서수량(>80g)이 84% 감소하여 고온 피해가 컸으며, 조풍 품종은 36%로 감소폭이 적었다. 괴경 생리장해(이차생장, 열개, 기형)는 폭염구에서 전반적으로 증가하는 경향이었다. 열개 발생률이 가장 적은 품종은 '조풍'이었다. 폭염처리 하에서 괴경은 길어졌는데, 이는 감자의 상품성이 낮아지는 것을 의미한다. 괴경의 경도와 건물률은 폭염 처리를 받았을 때 유의하게 낮아 지는 경향을 보였다. 따라서 폭염 조건에서 감자 재배 시 수량 감소와 품질 피해를 입으며, 폭염 적응성이 높은 품종은 '조풍'이었다. 이상의 연구 결과는 감자 재배 농가 및 내서성 품종 육종 등에 기초 자료로 사용될 수 있을 거라 판단된다.
