朴燦憲,都成國 東亞大學校附設基礎科學硏究所 1985 基礎科學硏究論文集 Vol.2 No.1

In order to improve the crease recovery and dyeing property of the cotton fabric, it was treated with Ν-methylolacrylamide (NMA). Several treating conditions, which include the concentration of NMA, curing temperature, curing time and concentration of catalyst(NH₄Cl), were varied. The acrylamidomethylated cellulose(AMC) fabrics treated with conditions above were dyed with acid dye(C.I. Acid Yellow99) containing nucleophilic group in alkaline bath. The crease recovery, handle value, color-difference and amount of dye of of dayd AMC were investigated. 1. The crease recoverry, handle value, amount of dye on the fabric and color difference are increased with increasing the concentration of NMA. 2. With the increase of curing temperature, the color-difference is increased, the maximum value of crease recovery is found at 140℃, and the handale value is decreased. 3. In accordance with the lapse of curing time, the crease recovery and the color-difference, however slightly over 6 minites, are increased, and the handle value is decreased. 4. The crease recovery, handle value, and color-differdnce are not varied remarkably by increasing the concentration of catalyst in aqueous NMA solution.

Hepatocellular carcinoma frequently metastasizes through direct extension, lymphatic, and hematogenous routes. The most common sites of metastasis are the lungs and the lymph nodes, glands, bones, spleen, kidneys, colon, and pleura are the sites of metastasis in decreasing order of frequency. But metastasis to the ovary is very rare. It is thought that metastasize to the ovary occurs through infiltration or dissemination. However, we observed ovarian metastasis of primary hepatic tumor in a 34-year old female who suffered from lower abdominal pain. At first, it was diagnosed as a primary ovarian tumor. But histologically, it presented sinusoidal pattern surrounded by the tumor cells and contained rounded by the tumor cells and contained round hyaline globules in minority of the cytoplasm. Then, the histologic features of percutaneous, sono-guided liver biopsy speecimen of the liver mass are similar to those of resected ovarian tissues. Therefore, we concluded that ovarian tumor was originated from hepatocellular carcinoma. In summary, this report examines a case of hepatocellular carcinoma with ovarian metastasis in a female and reviews the literature.

This study aims at improving work reliability. It proposes a way to overcome the limitations of current scheduling methods by providing a new framework, CPAM(Construction Process Analysis Model) based on the lean principles. It suggests methods which improve work reliability and production effectiveness with variability control methods. Also it suggests methods which reduce inventories of materials and equipment and WIP(Work In Process) using two techniques; Lookahead Schedule and Weekly Work Plan. The contribution of this research also includes that it assumes planning as a process of reducing uncertainty and maximizing throughput, counter-posing plan reliability to resource redundancy as alternative strategies for managing in conditions of uncertain work flow.

The entire duration of the research work was from December-2000 to July-2002. Site measurement were conducted during various season, in a dry season(December), in rainfall, in seed-sowing time and also collecting data from the rural public organizations related to water management was done and examined during the mid of research work. Generally, the Dong Jin River watershed contains small three Creeks, KoBu, DongJin(including JeongEup and ChilBo, WonPyong). It was further divided into 32 sub-watersheds which comprises of further 5, 18, 9 watersheds in the creeks respectively. Inflow loading to the river was calculated from measurement of general water quality and quantity and these field surveys were made thrice times in agricultural drainage channels, where fertilizers and pesticides leaching from the surface have an direct effect for the deterioration of the several creek and river. Estimation of contaminant loading has been done by using unit loading based on the notification No. 1999 - 143 of the Ministry of Environment. Most of estimated loading data reported during the research work were slightly higher when compared with the notification of the Ministry but they do not have any significant effect. It was assumed that sub-watersheds have considerable field survey loading data, which were affected due to non-point source pollution load as compared to point source. For investigation of surface rainfall ranging from .50㎜ during non-farming or .10 rainfall on the period of farming, BOD loadings in the field during farming showed slightly higher levels in comparison with discharge loadings, T-N also showed the similar trend as discussed earlier.

본 논문에서은, 운전자의 편의성과 안전성을 도모하기 위해 영상-음성 통합인식을 이용한 자동차 내부기기 제어를 목적으로 한다. 동영상 파일인 AVI로 영상인식과 음성인식에 사용할 DB를 구성하였다. 영상인식 부분에서 Lip Reading Merhod를 이용하여 입술의 움직임에 대한 특징벡터를 추출하였고, 음성인식 부분에선 MFCC로서 음성에 대한 특징벡터를 추출하엿다. 추출된 각각의 특징벡터들을 HTK에 적용하여 영상-음성 통합 인식기를 구현하였다. 본 논문에서 구현된 시스템에 의하여 인식을 수행한 결과. 기존의 음성 인식기에서 잡음환경으로 인해 유발되었던 오인식 결과들이 영상 인식기와의 상호 보완된 처리로 인하여 크게 개선될 수 있었다. In this paper, we use image and speech integrated recognition system for the convenience and safety of drivers in order to control equipments of inside of car. We make DB, constructed on AVI files, for the image and speech recognition. We get features from the movement of lip using Lip Reading Method in image recognition and one from the MFCC(Mel Frequency Cepstral Coefficients) in the part of speech recognition. We integrate using, these features which will be applied to HTK recognition engine we construct the image and speech recognition system. We show that wrong recognition results, induced by noise environment in speech recognition system can be corrected by image recognition system.

Since the degumming of silk fabrics with alkaline solutions has been suspected of causing some degradation of silk fibroin and different degumming conditions have influenced the degumming ratio, raw silk fabrics were treated with aqueous solutions of Na₂CO₃, marseilles soap, Na₂CO₃-marseilles soap(2:1, w/w), and Na₂CO₃-marseilles soap (1:2, w/w) under different conditions such as the variation of time, concentration and temperature to investigate the extent of damage to the silk fabrics and to infer the removed quantity of sericin by reaction of degummed silk fabric with ninhydrin solution, which indicated the quantitative change of amino group content in polypeptide chains. The degumming ratio varied with different degumming conditions but the maximum value was approximately 24% in all conditions except soap solution degummed fabrics(max. ca. 17%). Especially, in the case of 15% solutions of Na₂CO₃ and Na₂CO₃-Marseilles soap(2:1, w/w) at 100℃, it reached about 20% even in 30 minutes. The increase in amino group content in silk fabrics showing their degumming ratios of more than about 20% was considered as the damage to the silk fabrics due to the some degradation of silk fibroin.

Evans syndrome is defined as a simultaneous or sequential occurrence of autoimmune hemolytic anemia and autoimmune thrombocytopenia. Autoimmune hemolytic anemia (AIHA) is usually induced by IgG warm autoantibody or cold-active IgM antibodies reacting specifically with antigens associated with a patient's RBC. AIHA is a fairly uncommon disorder, with estimates of the incidence at 1 to 3 cases per 100,000 per year. Mixed-type AIHA is a relatively uncommon form of AIHA, with studies noting the incidence of 7-8% among cases of AIHA. We experienced a patient, 46-year-old woman who was diagnosed having a very rare clinical presentation of mixed warm and cold antibody mediated Evans syndrome. She was treated with corticosteroid therapy only and has been maintaining a complete response for 15 weeks. 저자들은 혼합형의 자가면역성 용혈성 빈혈과 자가면역성 혈소판 감소증이 동시에 발생한 혼합형 Evans 증후군으로 진단하고 스테로이드 요법 후 혈액학적으로 회복된 상태로 15주가 지난 현재 steroid 5 mg/일 까지 감량한 상태에서 추적 관찰 치료중인 46세 여자 환자를 경험하였기에 문헌 고찰과 함께 보고하는 바이다.
