The determination of surface middleography is believed to be extremely important in the areas of contact mechanics, adhesion and friction. In order to describe middleography of various rubbed and hardened surface, the wear test was carried out under different experimental conditions in dry friction. And fractal descriptors was applied to rubbed and hardened surface of laser modified steel with image processing system. These descriptors to analyze surface structure are fractal dimension. Surface fractal dimension can be determined by sum of intensity difference of surface pixel. middleography of rubbed and hardened surface can be effectively obtained by fractal dimensions.

It would be the best way to use the concept of context for the analysis and arrangement of the order and layout on the out-door space in korean traditional upper-class houses. The concepts of context are understand that spritual contexts are the dimension of life. The results are as follows. 1. The investigation in spritual content. The upperclass houses in Cho-sun dynasty are divided to the clod space and the opened space according to the character. Besides, Ma-Bang is limmited by status, sex, age also permitted as sectional space and processional space. 2. The type of Ma-Bang depending on the approach-sequence. : Space type of approaching form to the main gate has the up-down rectangular, and makes an meaning a upward tendencing Ma-dang. : Haengrang Ma-Bang type from the main gate has a left-right rectangular Ma-Bang which has a narrow front view and a wide side view. : Putting all accounts together, typical Ma-Bang 3. The house has composed with devided space and layout dependently in home site by O-Haeng. The houses have enclosed places with a fence and: a buildings; therefore, the area of space characterised by an enclosure. An Ma-Bang is exposed to the ascent and deeply concentrated and is located highly in visual effect. The plan and elevation have been made use of a quadrangle which means that the earth is in the Samjae. 4. The elevation in the Sarang Ma-Bang has been made use of a verification of a quadrangle and a triangle, a colonnade, a piloities, a high foundation stone, and shape of projection which means Yang. 5. The orientation of an ancestral shrine have been located in east-north which is symbolized a life, brightness, and signed prophetic of something good. The locations of an ancestral shrine have been decided on the place of Sarang-Chae and Ma-Bang. The traditional house-form from the period of Samkuk to Chosun Dynasty have been expressed & willingly purposed with their own spritual contexts, so they didn't touched the danger on the mistaken contextual creation.

Rural of Koreas has rapidly changed through the process of industrialization and urbanization. During past 30 years, development differences between urban and rural, metroplitan area and area derived from a highly economic growth, bring about dual specialization that deepens overpopulation and sparsity. Therefore, with a new concern about rural, necessity of rural development policy that developes a settlement and life area for settlement for ensuing stablized settlement and living activity of rural people, has been drived step by step. For rural welfare establishment that is settled and good hereafter, this study aims at attempting a theoretical approach about the way of development for rural settlement as a new rural development strategy through examination of today's rural reality, under assumption that rural people must be able to obtain stable jobs and to be pleasant without leaving rural area, and rural settlement to be able to enjoy urban advantages must be realized. Therefore, items that must be obtained basically rural area to be a human settlement space are equipment connected with a dwelling house, production, consumption, job relaxation, infrastructure connected with transportation or communication network and environment. By the way, the best function of a human settlement space makes a basic pleasant settlement area to be in the middle of that. Then rationalization of land use must be realized as being a best condition for human life around space of a dewelling house. Besides, spacial accessibility about all equipment of inhabitants must be easy. That is, economic distance, social distance and cultural distance as well as spacial distance must be included. Also, those spacial functions must be realized on a basis of suitable enironment for a human settlement life. At the same tiem, the upper area must be connected with the lower area as the system of spacial settlement in settlement space. But truely, as rural people can't satisfy with services of the surrounding rural areas, they desire better city or metroplitan. The these problems bring about inequality between urban and rural. Therefore, here are urgent reasons that must be done rearing of rural central town and rural integrated development of unit area. So, these dys, to correct maldistribution of land use and inequality of settlement space that Korean society faces on, new strategies of rural integrated development for lift area for settlement than gives the meaning. That rural areas become like a place for human settlement life will be able to be chosen in the view of humanism. The say of thinking of rural residents(Jukans-myun, Anseong-gun, Kyeonggi-do) was surveyed in order to develop new rural settlement planning. From the data collected in this survey, rural life-style, view on traditional rural life, agriculture, farming, agri-policy, social attitude, and degree of satifaction of rural life, etc, were analyzed. Firstly, most of rural residents interviewed in this survey have the opinion of not leaving their home village if living conditions improved to a reasonable level in the near future. In decision-making process of village affairs, they want to participate actively and equally. Secondly, in spite of their acceptance of agriculture as a vital sector destined to national security, most of them think that framing should be little of promise. Thirdly, they have the negative attitude to urban-oriented social valued and also to the agricultural policy, while seeking consolation through human and traditional viewing of rural life style. Therefore, in the development of new rural settlement model, idea-making should be directed to the betterment of communal value of village life, stability of rural economy, rationalization of rural life style and enhancement of rural-type happiness.

목적 : 2002년 말 중국에서 SARS가 발생한 이후 국내에서도 2003년 10월까지 총 3명의 추정환자, 17명의 의심환자가 보고되었다. 향후 추가적인 SARS의 유행이 우려되는 상황에서, 그간의 SARS 환자 진료에 있어서의 실질적인 준비사항, 진료 현황 등에 대한 조사를 통해 문제점을 파악하여, 향후 더 나은 대비가 될 수 있도록 개선점을 제시하고자 하였다. 재료 및 방법 : SARS로 의심되는 환자를 진료 경험이 있는 병원의료진을 대상으로 2003년 10월에 설문조사를 실시하였다. 설문에는 SARS 환자 진료 시의 실질적인 조치, 진료 현황, 병실, 응급실 및 외래에서의 격리 시설과 준비사항, 보건당국의 관리와 지원에 관한 사항을 포함하였다. 결과 : 대상이 되는 22개 병원 중 17개(17/22, 77.2%) 병원이 설문에 응하였다. SARS 환자를 위한 격리실은 응급실, 외래, 일반병실 및 중환자실에서 각각 9개(9/17, 52.9%), 5개(5/17, 29.4%), 15개(15/16, 93.7%), 4개(4/16, 25%) 병원에서 음압처리가 되어있지 않은 일인실 혹은 다인실이 사용되었고, 1개(1/16, 6.3%) 병원에서만 일반병실에서 음압격리실이 운영되었다. 입원환자의 진찰 시 개인보호구의 착용은 거의 모든 의료기관에서 이루어졌다. 보건당국에서 SARS지정병원의 시설 등을 사전에 확인한 곳은 1곳(1/12, 8.3%)이였고, 14개 병원(14/15, 93.3%)에서는 보건당국에 의뢰한 검사결과를 통하 받지 못하였다. 결론 : 의료기관에서 SARS 환자용 격리실뿐만 아니라 기존의 격리실 설비 등이 미흡하였으며, 특히 중환자실 및 외래의 준비가 더욱 부족하였다. 보건당국의 의료기관에 대한 종합적인 지원이 부족하였고, 병원과의 원활한 연계가 잘 이루어지지 않았다. SARS 만이 아닌 격리를 필요로 하는 질환의 적절한 진료를 위해 향후 병원 시설의 정비와 정부차원에서의 보다 구체적이고 실질적인 대책마련이 필요하다. Background : There was an worldwide outbreak of the Severe Acute Respiratory Syndrome (SARS) originated from China in late 2002. During that period three cases of suspected SARS and 17 cases of probable SARS were reported in Korea. With the concerns about the reemergence of SARS-coV transmission, it is important to be prepared for any possibility. So, this study is aimed to analysis the past measures in managing SARS and propose the amendatory plans to improve the preparedness. Materials & Methods : Questionnaires were collected among clinicians with any experience in managing the probable or suspected SARS cases in Oct. 2003. 17 out of 22 hospitals responded to the questionnaire. The contents in the questionnaire were practical activities, personal equipments, response plans, isolation facilities in emergency centers, outpatient clinics, general wards and intensive care units, and relationship with the public health department. Results : The dedicated isolation rooms in emergency centers, outpatient clinics, general wards, and intensive care units were prepared in 9 (9/17, 52.9%), 5 (5/17, 29.4%), 15 (15/16, 93.7%), and 4 (4/16, 25.0%) hospitals, respectively. Except for one hospital that newly made negative pressure room for SARS, single or multi-bed rooms without airborne infection control were used in all the other hospitals. The personal precaution principles were kept quite well in general wards. Before the designation of SARS hospital by the public health department prior evalution to see if the hospital was suitable for managing SARS was conducted in only 1 (1/12, 8.3%) hospital. The results of laboratory diagnosis were reported back in 1 (1/15, 6.6%) hospital. Conclusions : The isolation facilities which can control airborne infection were almost deficient not only for SARS but also for other respiratory transmissible diseases. For the infection control of transmissible diseases including SARS, more investment is needed on medical facilities and comprehensive support from the public health department required.

This study was done to observe the distributions of Oxytocinergic and Vasopressinergic neurons in the hypothalamus of the cow. For the immunohistochemical staining, sections were reacted with the following sequence of solutions: monoclonal anti-vasopressin and anti-oxytocin, biotinylated anti-mouse IgG, avidin-biotin peroxidase complex, and Ni-DAB. The results observed under light microscope were summarized as follows. Our immunohistochemical investigations reveal both vasopressinergic and oxytocinergic neurons in the supraoptic nucleus(SON), paraventricular nucleus(PVN), accessory supraoptic nucleus (ASN), periventricular nucleus(PN), suprachiasmatic nucleus(SCN), and arcuate nucleus(AN), but these two types of neurons were mainly distributed in the PVN and SON and the ratio of the number of vasopressinergic neurons to that of oxytocinergic neurons was 1:1.30 in the PVN, and 1:1.00 in the SON. These two types of neurons were round, oval and spindle-shaped and cell size was 30-55um.

<P>OBJECTIVES/HYPOTHESIS: It is known that arginase may be a regulator of diverse pathways, including production of nitric oxide (NO). Increased expression of arginase has been reported in several inflammatory lung diseases, including allergic asthma, suggesting that this may be a common feature underlying the pathophysiology of airway hyperreactivity. Thus, arginase I and II may play a role in the pathogenesis of allergic rhinitis. The distribution pattern and level of expression of arginase I and II were therefore determined in normal and allergic nasal mucosa. STUDY DESIGN: Controlled, prospective study. METHODS: The distribution pattern and level of expression of arginase I and II in normal and allergic nasal mucosa were evaluated using RT-PCR, immunohistochemistry, and Western blotting. RESULTS: The level of expression of arginase I and II mRNA was increased in allergic nasal mucosa in comparison with normal nasal mucosa. In normal nasal mucosa, arginase I and II were expressed in the surface epithelium, submucosal glands, vascular endothelium, and fibroblasts. In allergic nasal mucosa, both enzymes were also localized to similar sites, in addition to inflammatory cells, and the level of expression were greatly increased compared with normal nasal mucosa. These findings were verified by Western blotting. CONCLUSIONS: These results indicate that arginase I and II may play a role in the pathophysiology of allergic rhinitis, and suggest the possible role of the L-arginine metabolic pathway through modulation of L-arginine availability as a substrate for nitric oxide synthase (NOS) and arginase in the pathogenesis of allergic rhinitis.</P>

Case Reports : A Case of Spitzoid Melanoma

( Heung Yeol Kim ),( Jong Hyun Yoon ),( Eun Byul Cho ),( Eun Ju Park ),( Kwang Ho Kim ),( Kwang Joong Kim ) 대한피부과학회 2015 Annals of Dermatology Vol.27 No.3

Spitzoid melanoma is a subtype of melanoma that, clinically and histologically, resembles a Spitz nevus. Clinically, spitzoid melanomas usually evolve from amelanotic nodular lesions, growing to 1 cm or more in diameter. They often remain clinically undiagnosed because of their wide variety of clinical appearances and a lack of pigmentation. Distinguishing a Spitz nevus from a spitzoid melanoma can be extremely difficult. Features that favor the diagnosis of a spitzoid melanoma are asymmetrical shape, diameter greater than 1 cm, a lesion with a deep invasive component, and a high degree of cytologic atypia. There have been only rare reports in the literature of the presence of giant cells in malignant melanoma, and the presence of these cells may result in its misdiagnosis as a histiocytic tumor. We present a case of spitzoid melanoma on the right ankle of a 22-year-old-woman. (Ann Dermatol 27(2) 206∼209, 2015)

Pilot Symbol Assisted Modulation(PSAM) is a conventional method for estimating a channel in OFDM. And Extended Symbol Aided Estimation(ESAE), which uses not only the pilot symbols like PSAM but also the previously estimated fading values, is used for only single-carrier system. ESAE has a better performance in MSE than PSAM. But ESAE needs much more computational complexity than those of PSAM. Also, ESAE has a serious problem in MSE performance in case that the value of channel estimation error are accumulated. For the sake of these problems in conventional methods, we propose a channel estimation method for OFDM, which has a good performance and computational complexity.
