본 연구는 비오톱 지도와 항공 라이다 자료만을 이용해 GIS 분석기법을 적용하여 개개의 비오톱에 대한 기후분석 및 평가정보를 제공함을 목적으로 하고 있다. 1차 분석단계에서 비오톱 지도로부터 면적, 경사, 경사길이, 표면특성, 바람통로 기능, 바람통로 폭, 바람통로 장애물 요소를 각각 구하여 냉기/신선기 생성 및 바람통로 기능을 평가하였으며 2차 분석단계에서는 이들 요소를 종합하여 기후평가를 수행하여 비오톱 단위 별로 기후평가 자료를 생성하였다. 항공라이다 자료는 비오톱을 이용한 바람통로 분석에 유효하였다. 평가인자와 평가 등급 간의 상관성을 그래프 및 상관계수를 통해 확인한 결과 냉기/신선기 생성 등급과 Surface_GRD 평균값과의 상관계수가 (-)0.967로 높게 나타났으며 바람통로 기능에서는 등급별 Function_GRD 평균값과의 상관계수가 (-)0.884, Obstacle_GRD 평균값과의 상관계수는 (-)0.834로 나타났다. 기후평가 등급과 WindCorridor_GRD 상관계수는 0.928, 기후평가 등급과 ColdAir_GRD 상관계수는 0.855로 나타나 비오톱의 WindCorridor_GRD가 ColdAir_GRD에 비해 상관성이 높게 나타났으며 항공사진 정사영상을 이용한 육안 검수에서도 기후평가 및 등급화 결과가 잘 반영된 것으로 나타났다. 결과적으로, 비오톱 지도와 항공라이다 자료를 이용해 기후 분석 및 평가 방법을 적용한 결과 광명-시흥시 보금자리 주택개발 예정지의 기후평가등급에 따른 면적분포 비율은 1등급 18.5%, 2등급 18.2%, 3등급 30.7%, 4등급 25.2%, 5등급 7.4% 순으로 나타났으며 본 연구방법을 통해 기후평가 정보를 각각의 비오톱 단위별로 통계적 정보와 함께 제시할 수 있었다. The main purpose of this paper is to deliver a climate analysis and evaluation method based on GIS by using airborne LiDAR data and Biotop type map and to provide spatial information of climate analysis and evaluation based on Biotop type Map. At first stage, the area, slope, slope length, surface, wind corridor function and width, and obstacle factors were analyzed to obtain cold/fresh air production and wind corridor evaluation. In addition, climate evaluation was derived from those two results in the second stage. Airborne LiDAR data are useful in wind corridor analysis during the study. Correlation analysis results show that ColdAir_GRD grade was highly correlated with Surface_GRD (-0.967461139) and WindCorridor_ GRD was highly correlated with Function_GRD (-0.883883476) and Obstacle_GRD (-0.834057656). Climate Evaluation GRID was highly correlated with WindCorridor_GRD (0.927554516) than ColdAir_GRD (0.855051646). Visual validations of climate analysis and evaluation results were performed by using aerial ortho-photo image, which shows that the climate evaluation results were well related with in-situ condition. At the end, we applied climate analysis and evaluation by using Biotop map and airborne LiDAR data in Gwangmyung-Shiheung City, candidate for the Bogeumjari Housing District. The results show that the aerial percentile of the 1st Grade is 18.5%, 2nd Grade is 18.2%, 3rd Grade is 30.7%, 4th Grade is 25.2%, and 5th Grade is 7.4%. This study process provided both the spatial analysis and evaluation of climate information and statistics on behalf of each Biotop type.

Cytologlc evaluation of cerebrospinal fluid(CSF) is an effective mean for diagnosing many disorders involving the central nervous systems(CNS). One of the most important reasons for cytologic examination of CSF is to detect metastatic or primary neoplasms of the CNS. We did a retrospective study of 1,438 CSF specimens obtained between 1992 and 1996. A total of 1,205 adult and 233 pediatric CSF specimens from 947 patients were accessed at the Department of Pathology of Seoul National University Hospital and Children's Hospital, respectively. Among 1,438 CSF cytology specimens, 169 cases(11.8%, 77 patients) including 135 adult cases(59 patients) and 34 pediatric cases(18 patients) were positive for malignant cells. Diagnoses included 50 metastatic carcinomas(adult, 60; pediatric, 0); 46 malignant lymphomas(adult, 44; pediatric, 2); 21 leukemias(adult, 20; pediatric, 1); 4 retinoblastomas(adult, 0; pediatric 4); 2 rhabdomyosarcomas(adult, 0; pediatric, 2); 1 multiple myeloma(adult, 1; pediatric, 0), and 35 primary CNS neoplasms(adult, 10; pediatric, 25). The most commonly identified metastatic carcinomas in adults were adenocarcinoma. Their primary sites were the lung, gastrointestinal tract, and breast in order of frequency. The most common primary CNS neoplasm in children was medulloblastoma.

Statement of problem: The adhesion between titanium and ceramic is less optimal than conventional metal-ceramic bonding, due to reaction layer form on cast titanium surface during porcelain firing. Purpose: This study characterized the effect of titanium-ceramic adhesion after gold and TiN coating on cast and wrought titanium substrates. Material and method: Six groups of ASTM grade II commercially pure titanium and cast titanium specimens$(13mm{\times}13mm{\times}1mm)$ were prepared(n=8). The conventional Au-Pd-In alloy served as the control. All specimens were sandblasted with $110{\mu}m\;Al_2O_3$ particles and ultrasonically cleaned for 5min in deionized water and dried in air before porcelain firing. An ultra-low-fusing dental porcelain (Vita Titankeramik) was fused on titanium surfaces. Porcelain was debonded by a biaxial flexure test at a cross head speed of 0.25mm/min. The excellent titanium-ceramic adherence was exhibited by the presence of a dentin porcelain layer on the specimen surface after the biaxial flexure test. Area fraction of adherent porcelain (AFAP) was determined by SEM/EDS. Numerical results were statistically analyzed by one-way ANOVA and Student-Newman-Keuls test at ${\alpha}=0.05$. Results: The AFAP value of cast titanium was greatest in the group 2 with TiN coating, followed by group 1 with Au coating and the group 3 with $Al_2O_3$ sandblasting. Significant statistical difference was found between the group 1, 2 and the group 3 (p<.05). The AFAP value of wrought titanium was greatest in the group 5 with TiN coating, followed by the group 4 with Au coating and the group 6 with $Al_2O_3$ sandblasting. Conclusion: No significant difference was observed among the three groups (p>.05). The AFAP values of the cast titanium and the wrought titanium were similar. However the group treated with $Al_2O_3$ sandblasting showed significantly lower value (p<.05).

Small cell carcinoma of the lung is characterized by cells with finely stippled chromatin and scanty cytoplasm as well as a particularly aggressive clinical course and favorable response to the chemotherapy. Recently percutaneous fine needle aspiration (FNA) biopsy has become both widely established and highly respected for the diagnosis of lung cancer. However metastatic small cell carcinoma of lymph node should be cytologically differentiated from the small round cell tumor of particular sites, especially malignant lymphoma, because small ceil carcinoma of classic oat cell type nay simulate small cell non-Hodgkin's lymphoma. We report five cases of metastatic small cell carcinoma of in-termediate cell type diagnosed by FNA of the enlarged lymph nodes of the neck and axilla. The cytologic smears contained diffuse small neoplastic cells larger than lymphocytes with dense, pyknotic nuclei and extremely scanty cytoplasm. Apparently viable large tumor cells have vesicular nuclei with granular, sometimes very coarse chromatin. The characteristic cytologic features of small cell carcinoma as compared to malignant lymphoma were as follows.: 1) small cells with dense pyknotic nuclei are evenly distributed in the background of apparently viable larger tumor cells, admixed with mature lymphocytes and phagocytic macrophages. 2) small loose aggregates of cells with nuclear melding are indicative of small cell carcinoma rather than non-Hodgkin's lymphoma. 3) the cytoplasmic and nuclear fragments of tumor necrosis are more dominant in the smears of small cell carcinoma. 4) nuclear membrane and nucleoli are generally indistinct in small cell carcinoma due to condensation of chromatin.

Kimura's disease is a chronic Inflammatory disorder of unknown etiology, presenting usually as a painless subcutaneous swelling in the head and neck region or in the lymph nodes. We experienced a case of Kimura's lymphadenitis with characteristic Warthin-Finkeldey type polykaryocytes by fine needle aspiration cytology. The patient was a 10-year old male with two enlarged lymph nodes in the postauricular area. Fine needle aspiration cytology from the lymph nodes disclosed hypercellular smears with some scattered eosinophils and polykaryocytes in a polymorphous lymphoid background. There were also fragmented vessel wails and activated endothelial cell clusters in the slightly necrotic background. The Warthin-Finkeldey type polykaryocytes had three to thirty nuclei and prominent nucleoli with cytoplasmic borders. Their nuclei were arranged in grapevine or ring shaped clusters. As these polykaryocytes could also be found in lymph nodes and extranodal tissues of both reactive and neoplastic lymphoid disorders, polykaryocytes themselves are clinically nonspecific. However, the morphologic features of the Warthin-Finkeldey type giant cells are quite different from the foreign body type or Langhans' type giant cells. When the characteristic cytologic features of Kimura's disease such as significant number of eosinophils in a background of lymphoid cells asd proliferation of vessels and endothelial cells are also observed in the smear, it is possible to suggest this diagnosis in the appropriate clinical setting.

Urinary cytology has become an essential element in the diagnosis and management of transitional ceil carcinoma(TCC) of the urinary tract. It has the advantage of being noninvasive, inexpensive, and easily accessible. Besides that it can even detect malignancy when unsuspected at cystoscopy. We report a retrospective review of urine cytology un the diagnosis of 83 TCC cases that underwent 295 cytologic evaluation. All patients had biopsy-proven TCC of the bladder, ureter and renal pelvis, The overall incidence of the positive cytology cases was 66.2%. To define the cytologic features of tumor cells, we tried to use three cytologic gradings such as "grade 1", "grade 2", and "grade 3" according to the cytologic degree of anaplastic neoplastic cells. These cytologic gades of TCC were relatively well correlated with the histologic grade and tumor invasiveness. This result suggests that the recognition of characteristic cellular features of TCC can suspect the histologic grade and tumor stage. The false negative TCC cases were 78.9%. They showed severe inflammatory or bloody background and a few neoplastic cells. Therefore, a cautious approach for accurate interpretation, personal experience, and proper fixation and processing could expand the role of urinary cytology.

This study was performed to evaluate the tensile bond strength and modulus of elasticity of three permanent soft denture liners (Molloplast $B^{(R)}$, Ufi Gel $C^{(R)},\;Tokuyama^{(R)}$) before and after thermocycling. And their water sorption were also evaluated. Each soft denture liner was bonded to PMMA denture base resin blocks and the tensile bond strength and modulus of elasticity were measured by using universal testing machine. For the water sorption, weight measured after immersion of sea denture liners in $37{\pm}1^{\circ}C$ water bath for 4 weeks. The results were as follows : 1. Molloplast $B^{(R)}$ had the highest tensile bond strength, while Tokuyama had the lowest tensile bond strength. There was no significant difference between $Tokuyama^{(R)}$ and Molloplast $B^{(R)}$ in the both nonthermocycling and thermocycling. There was significant difference in tensile strength of $Tokuyama^{(R)}$ before and after thermocycling(p<0.05). 2. For the modulus of elasticity, there was no significant difference between Ufi Gel $C^{(R)}\;and\;Tokuyama^{(R)}$ in the both nonthermocycling and thermocycling. There was significant difference in modulus of elasticity of $Tokuyama^{(R)}$ before and after thermocycling(p<0.05). 3 The failure modes of Molloplast $B^{(R)}$ and Ufi Gel $C^{(R)}$ were mainley adhesive type and that of $Tokuyama^{(R)}$ was mainly mixed type in case of nonthermocycling and cohesive type after thermocycling. 4. The water sorption of each soft liners was within ${\pm}2%$ in times (p<0.05) but. there was no significant difference among the soft liners in times.

본 실험은 김치의 유통기한을 연장하고자 배추김치에 열처리 및 천연보존료를 첨가하여 그 효과를 조사하였다. 400g의 배추김치를 각각 원형 polyethylene 플라스틱 용기에 담고 90℃에서 120분 처리하였을 때, 2.0 log₁?CFU/g만큼 총균수가 감소하였으나 열처리 10분 만에 용기의 변형이 일어났고, 김치의 관능변화가 감지되어 부적절한 조건으로 판정되었다. 필름 파우치에 김치를 옮겨 열처리하였을 때는 80℃에서 30분 이하로 열처리하였을 때 0.3 log₁?CFU/g의 저해효과를 보여 효과는 크지 않았지만 김치의 관능변화를 일으키지 않는 적정조건이었다. 반면에, 배추 조직의 느린 열전달과 열처리 시 관능 변화 특성을 고려하여 김치 부재료 양념을 절임배추와 혼합 전 별도 열처리를 실시한 결과, 80℃ 이하에서 30분 열처리하였을 때 총 균수를 0.5 log₁?CFU/g, 그리고 유산균을 1.0 log₁?CFU/g만큼 저해하여 배추김치 살균보다도 더 효과적인 방법으로 판명되었다. 또한, 나이신과 유카추추물을 첨가한 김치를 한 달간 저장하며 미생물의 저해 효과를 확인한 결과 5℃에 보관할 때에 두 처리구 모두 저장기간 동안 유산균의 생육을 저해하는 효과를 보였다. 나이신과 유카추출물의 경우 모두 낮은 온도에서(5℃) 높은 초기 미생물의 저해 효과를 보였다. 이 연구 결과는 저온 살균법의 물리적 방법과 나이신 또는 유카추출물과 같은 천연보존료를 사용하는 화학적방법이 각각 김치의 초기 미생물을 감소시키고 유통기간 동안 미생물의 생육속도를 저해하는데 효과적임을 보여준다. For extension of storage period of cabbage-kimchi, effects of heat treatment as well as nisin or yucca extract were examined on the growth of microbes. Firstly, when kimchi was heated at various temperatures in polyethylene plastic bottle or membrane pouch, the optimum inhibitory condition giving no sensory change was at 80℃ for 30 min in a plastic membrane pouch and this treatment made a reduction of 0.3 log₁?CFU/g in total microbes. The result showed that use of plastic bottle was inefficient due to low heat transfer rate. Interestingly, pasteurization of seasoning pastes at 80℃ for 30 min separately from cabbage resulted in better inhibitory effect reducing 0.5 log₁?CFU/g of total bacteria and 1.0 log₁?CFU/g of lactic acid bacteria, and this operation was regarded as a promising inhibitory method. Secondly, when nisin and yucca extract were separately added in kimchi, microbial growth was inhibited during storage period and their inhibition effects were enhanced at lower temperature.
