This study was carried out to predict the amount of energy consumed by a ventilator installed in the terminal end of a common duct system. It is in which that the partial load control is generally performed. The air volume rate for the central ventilation system of the kitchen and bathroom of each household in an apartment is exhausted through a common duct system regardless of the position of each household within the complex. This air volume rate should be the same regardless of the location of each household. Since the common duct system is installed vertically, and is installed ventilator in terminal for the effective ventilation. Also, the pressure difference of each household increases with the vertical height. Thereby, the air volume rate exhausted on each household becomes different. KARSE has established a standard for constant static pressure ventilators with a constant flow rate damper in the branch duct of the common duct system. A control strategy for partial load control that can save energy must be considered in ventilation systems with common ducts. This paper compares the energy consumption of two control methods and suggests an energy saving control system.

An isolated granulocytic sarcoma (chloroma) of the left ovary occured in the absence of leukemia in a 12-year-old woman. This lesion is defined as a localized tumor mass composed of immature cells of the granulocytic series. Granulocytic sarcomas can occur at extramedullary sites including ovary but, isolated myelosarcoma in the absence of usual manifestations of AML may be rare and has some difficulties in diagnosis. Contrary to findings in other series, granulocytic sarcoma arising in this nonleukemic patient did not progress to acute leukemia during two years she has been followed.

Performance improvement of local exhaust system used in toilet and cooking place are main concern in a field of ventilation. In Korea, There are many high riser residential apartments in recent years. These buildings were not viewed as being major contributors to exhaust pollutants producted in indoor. It was because many engineers thought that exhaust in high riser building depends on stack effect. This study investigates on the performance improvement of terminal device, roof fan, of vertical spiral duct used in high riser residential apartments. This paper focuses mainly on the effect of accessories, number or shape of blades, composed of roof fan with function of exhaust air volume of toilet and cooking place. Roof fan with 10 blades is observed at optimum exhaust performance in this study.

Eosinophilic gastroenteritis is a rare disease of unknown etiology. It is characterized by massive tissue infiltration of eosinophils in the layer of any area of gastrointestinal tract, increased peripheral blood eosinophil count and various gastrointestinal symptoms. There are mucosal, muscular, and subserosal types, of which the subserosal type may result in the development of eosinophilic ascites. The cancer antigen (CA) 125 tumor associated antigen can be produced by normal cells of different tissues derived from the celomic epithelium. Serum CA-125 serum level can be increased in a diversity of physiological nonmalignant and malignant conditions. We experienced a 23-year-old female patient with eosinophilic gastroenteritis, who was presented with abdominal distention. The patient`s serum and ascitic fluid revealed increased CA-125 level. Serum CA-125 level was normalized following the administration of corticosteroids. We report this case with a review of relevant literature. (Korean J Asthma Allergy Clin Immunol 2006;26:167-171)

Recently, the Korea-US FTA was signed. In order to gain competitive power in all divisions of the domestic industry, Technical standards should be internationalized. The purpose of this study is to present a plan for the advancement of technology in the field of Building Mechanical facility. First, We review the configuration of the IMC established in the United States. Configuration method of the IMC was confirmed by ventilation system,
지형/지물 이미지 데이타베이스를 위한 형태 특징 추출 방법

항공 및 위성 사진과 같은 지형/지물 이미지는 대부분 비슷한 색상과 질감을 갖는다. 따라서 지형/지물 이미지 데이타베이스에서 질의 이미지를 정확하게 검색하기 위해서는 이미지의 형태 특징을 추출하는 것이 매우 중요하다. 본 논문에서는 지형/지물 이미지 검색을 위한 형태 특징 추출 방법을 제안한다. 이 방법은 이미지내 홀(hole)이 있거나 이미지가 연결되지 않은 영역들로 구성되어 있을 경우에도 형태 특징들을 효과적으로 추출할 수 있다. 그리고 세그멘테이션(segmentation)과 같은 특징 추출의 전처리 과정(pre-processing)에서 발생할 수 있는 오류에 강인하다. 본 논문에서 제안하는 방법이 기존의 방법들보다 우수함을 다양한 이미지 검색 실험을 통해 보인다. Topographical images such as aerial and satellite images are usually similar with respect to colors and textures but not in shapes. Thus shape features of the images and the methods of extracting them become critical for effective image retrieval from topographical image databases. In this paper, we propose a shape feature extraction method for topographical image retrieval. The method extracts a set of attributes which can model the presence of holes and disconnected regions in images and is tolerant to pre-processing, more specifically segmentation, errors. Various experiments suggest that retrieval using attributes extracted using the proposed method performs better than using existing shape feature extraction methods.
