文勝義,金日坤 新羅大學校 1983 論文集 Vol.14 No.-

The main purpose of this study is to clarify the difference of surface air climatology between the east and west coasts of the Korean Peninsula using the surface climatic elements. It was clarified that some climatic elements (precipitation, temperatures, rainy day, vapor pressure, relative humidity, surface air pressure) except diurnal range of temperature and wind speed show considerable difference between the east and west coasts of the Korean Peninsula. It was examined synoptically the reason which concern the regional difference. The effect of monsoon, adding the effect of Jangma front in summer produce the difference of surface air climatology between the east and west coasts of the Koreane Peninsula. Seasonal change of the surface climate along the east and west coasts of the Korean Peninsula was also dealt in this study.

옥수수 그릿츠의 등온 흡습 성질

金成坤 단국대학교 1988 論文集 Vol.22 No.-

Sorption properties of corn grits, differing in particle sizes, stored for 384 hours at 20℃ and relative humidities of 33~86% were analyzed. Corn grits of initial moisture contents of 8.0~8.6% showed adsorption and desorption above RH 57% and below RH 44%, respe ctively. From the estimation of the sorption rate at arbitray humidity an emperical equation was obtained: log(dw/dt) = a logt + logb, where w is moisture content(%), t is time(hour), a is slope and c is intercept. Sorption rate constants increased in the order of grits 2 (12~16mesh), grits 1 (16~25mesh), grits 3 (40% on 36mesh) and grits 4 (90% thru 60mesh).

Whole soybean milk is a functional soymilk produced by mixing of soymilk and Bejee (soymilk residue) slurry. Application of enzymatic technology for disintegrating the coarse and fibrous materials in soymilk residue, and development of biomill reactor for reducing reaciton time make possible to produce new soymilk in domestic industry. Whole soybean milk is environmental affiliated product without discharging any waste such as Bejee ets. Whole soybeen milk has good taste and flavour without coarse mouthfeel induced by including Bejee particle, as well as contains more dietary fiber, protein, oligosaccharide, and other functional compounds than general soymilks. Important values of whole soybean are utilizing all nutritional properites from whole soybean without dicarding any of the insoluble solid. In this study, producing technologies and nutritional properties of whold soybean milk were investigated.

球狀黑鉛鑄鐵의 Pearlite 硬化能에 미치는 合金元素의 影響

柳成坤 啓明大學校 産業技術硏究所 1990 産業技術硏究所 論文報告集 Vol.12 No.-

The concept of pearlitic hardenability is described as the effect of alloying and cooling rate on inhibiting the formation of ferrite in ductile cast irons. Ferrite forms during solid state transformation around the graphite spheroid. As carbon diffuses through the ferrite ring, the graphite spheroid must enlarge and the ferrite ring must deform plastically to accomodate this growth. A model has been proposed to clarify this mechanism. The alloying effects of molybdenum, nickel, and copper were studied in a series of heats cast into a range of casting section sizes. Regression analysis was used to illustrate the effects of alloying and cooling rate on the microstructure of ductile cast irons.

Shape modeling is an important part of computer vision. Shape models help the tasks of object representation and recognition. In this paper, curve evolution and level set algorithms are used for extracting a shape within an image. This method is based on the ideas developed by Osher and Sethian to model propagating solid/liquid interfaces moving with curvature-dependent speeds. We propose the new generalized formulation and stopping function of evolution for more accurate extraction of shape. Our method canbe applied to model arbitrarily complex shapes and has the ability to dynamically sense the topological changes of the shape during the shape recovery process.

유전성 구상적혈구증환자에서 Parvovirus B19 감염에 의한 일과성 골수무형성증 1예

Hereditary spherocytosis is a kind of hemolytic anemia caused by defect of RBC membrane and show symptoms such as anemia, jaundice and splenomegaly. The disease become serious problem when the symptom of it become severe after infection and parvovirus B 19 are known to cause transient aplastic crisis in this disease. Human parvovirus B19 is a small, non-enveloped, single-stranded DNA virus. The virus is spread by respiratory droplets, and infects within erythroid progenitor cells, which results in the arrest of erythropoiesis. Erythema infectiosum is the primary clinical presentation linked to parvovirus B19 infection in childhood. The clinical features of this infection in healthy individuals are asymptomatic infection, acute arthritis and transient anemia. But, individuals with a history of hematologic abnormalities, including increased RBC destruction (eg, sickle cell disease, hereditary spherocytosis) or decreased RBC production (eg, iron deficiency anemia), can present with transient aplastic crisis. Patients with congenital or acquired immune deficiencies are at risk of developing chronic infection and lead to pure red cell aplasia. We report the case of transient aplastic crisis due to parvovirus BI9 infection in hereditary spherocytosis.

사용자 스케치와 예제 영상 질의에 의한 웹 기반 영상 검색 시스템

황병곤,이상열 대구대학교 정보통신연구소 2003 情報通信硏究 Vol.1 No.2

대부분의 멀티미디어 검색시스템은 아직까지 내용기반에 의한 검색기술이 실용적 사용이 어려우므로 텍스트기반 검색을 하고 있다. 본 논문에서는 Web상에서 미디어 정보를 검색하는 것으로, HTML문서상에 있는 텍스트 중 이미지의 표제나 이미지 링크상의 텍스트를 추출하여 색인 정보로 사용하였다. 이 텍스트 추출방법은 기존의 N-Gram색인 방법에 질의자의 선택 가중치를 부여하므로 검색 효율을 높일 수 있다. As most Multimedia retrieval system is using text based retrieval not be practical to content based retrieval can not be practical to it. In this paper, we retrieve multimedia contents in the web. After extracting the texts to express the name and link of images. We used them as indexing information in item. We add the weight of the user to the existing N-gram indexing method. Therefore, we can incase a retrieval efficiency.
