Purpose: Perforated gastric cancer (PGC) is rare and occurs in $1\∼4\%$ of all gastric cancers. Possible dissemination of tumor cells at the time of perforation of the gastric carcinoma has been a matter of concern. The intraoperative determination of what kind of operation should be done and how extensive the lymphnode dissection should be still remains controversial. The purpose of this study is to evaluate the factors influencing the survival and to determine the optimal treatment for PGC. Materials and Methods: A total of 42 patients were operated on for a perforated gastric carcinoma at Soonchunhyang University Chunan Hospital from 1983 to 2000. the age and the sexes of the patients, the location of perforation, the diameter of perforation, the histologic type of the tumor, the depth of wall invasion, the absence or presence of lymph node metastasis / distant metastasis, the stage of disease, the type of operation, and the outcomes were examined. Statistically significant differences were analyzed by using Fisher's exact test. Results: The stage distributions according to the UICC classification were 1 case of stage I, 6 cases of stage II, 17 cases of stage III, and 11 cases of stage IV. An emergency gastrectomy was done in 26 patients ($61.9\%$), with a 5-yr survival rate of $44\%$. The survival of patients was significantly influenced by the depth of wall invasion, the lymphnode metastasis, distant metastasis, the stage of disease, and the type of operation. Conclusions: an emergency gastrectomy is the treatment of choice for most patients with resectable PGC. Choosing more a optimistic surgical approach for potentially curative cases of PGC should be one way to increase the patient's survival rate.

이문수,송경헌,Song, Kyoung-Hun,Lee, Mun-Soo 배재대학교 자연과학연구소 1995 自然科學論文集 Vol.8 No.1

건열일축연신법에 의한 합성섬유의 연신은 높은 유리전이온도 때문에 대략 $150^{\circ}C$이상의 온도에서 행하여 지고 있다. 그러나, 팽윤습열연신법은 유기용매를 팽윤제로 사용하여 미세구조를 변화시키기 때문에 낮은 온도에서 연신 할 수 있는 특징을 갖고 있다. 본 연구에서는 비교적 낮은 온도인 $70^{\circ}C$에서 팽윤습열 일축연신에 의한 100% 아크릴섬유의 고강도화에 대하여 연구하였다. 연신능력은 연신일에 의하여 계상하였으며, 이 연신일은 연신응력과 변형 그리고 초기영율에 의하여 좌우됨을 알 수 있었다. 연신은 아크릴 섬유의 고강도를 위해 필요한 요인임을 확인할 수 있었다. 또한, 아크릴 섬유의 고강도화를 위한 분자배향도 및 결정화도 증가에 따른 연신조건의 효과와 물성 변화에 대하여 비교. 검토하였다. The stretching of synthetic fibers by hot dry process is very difficult, because these fibers have high glass transition temperature at above $150^{\circ}C$. But, we used a swell-wet stretching precess; the fibers are stretched in a swelling agent such as organic solvents at lower temperature. In this study, 100% acryl fibers were uniaxially stretched with free width at $70^{\circ}C$ by swell-wet process in organic solvents. The stretchability was estimated by stretching work. This work is concerned with stretching stress and strain, and initial modulus. We found that it is a good parameter for the estimatation of high strength to the acrylic fiber. The effects of stretching conditions on the molecular orientation for high strength and mechanical properties of PAN fibers were measured.

연구목적 : D형 인격은 국내에서는 아직 생소하며, 심혈관 질환을 비롯한 다양한 질환과의 관련성, 그리고 그 질환에 대한 예측인자로서의 가능성 등에 대해 아직까지 연구된 바가 거의 없다. 그러나, 기존 외국의 연구 결과들은 D형 인격이 심혈관 질환의 발병이나 경과에 중요한 예측인자가 될 수 있음을 보여 주었으며, 현재에도 관련 연구결과가 지속적으로 보고되고 있어 국내에서도 관련 연구가 요구되는 상황이다. 이에 본 저자들은 예비연구를 통해 D형 인격의 검사 도구인 DS14를 번안하고 이에 대한 신뢰도와 타당도를 검증함으로써, D형 인격 평가 척도의 표준화된 기준을 제시하고자 본 연구를 진행하였다. 방법 : 1차 조사에서는 총 17문항으로 구성된 DS14의 예비 척도를 국문으로 번역하여, 서울 및 경기도 안산지역에서 무작위 표집한 심혈관 질환이 없는 정상인 372명에게 작성하도록 하였다. 예비척도에서 척도화가 가능한 문항을 추출하여 14문항의 DS14를 완성하고, 그 신뢰도를 알아보았다. 또한 2차조사에서는 1차조사의 대상 중 40세 이상을 대조군으로 심혈관 질환 환자들과 DS14에 의한 D형 인격의 분포를 비교하였다. 결과 : 1차 조사에서 예비 척도의 분석결과 '사회적 억제' 하위척도의 10문항 중 7개의 문항이 결정되어 14문항의 DS14척도가 완성되었다. 부정적 정서와 사회적 억제 각 하위척도의 내적일치도를 나타내는 신뢰도계수는 각각 0.817, 0.797이었다. 2차조사에서는 관상동맥질환 군에서 일반인구군에 비해 D형 인격의 빈도가 유의하게 높음을 확인할 수 있었다. 결론 : 한국어판 DS14척도는 신뢰도와 타당도를 고려할 때 부정적 정서와 사회적 억제의 양상을 보이는 D형 인격의 평가에 유용한 척도로 생각된다. 또한 본 연구에서는 한국어판 DS14척도를 사용하여, 관상동맥질환의 예측인자로서 D형 인격의 가능성을 확인하였다. Objectives : The distressed personality (type-D) pattern, consisting of negative affectivity and social inhibition, has been shown by Denollet et al. For measuring the Type D characteristics, Denollet has devised the 14 item Type D scale (DS14). In the present study, this instrument was translated into Korean. The reliability and validity of the Korean DS14 was pilot tested. Methods : Preliminary version of the total 17-item DS14 scale was translated into Korean. 372 controls that did not have any coronary heart diseases (CHD) were randomly sampled in Seoul and Gyeonggi province. Preliminary Korean version was applied to controls and 14 items were finally selected to maximize reliability of the scale. We compared the distribution of type-D personality among the normal controls, hypertensive patients, and the CHD patients. Results : 7 of 10 items in social inhibition were selected and final 14-item version was made. The internal consistency of negative affectivity (0.817) and social inhibition (0.797) were high. In addition, the prevalence of type-D personality in the CHD patients group was significantly higher than normal controls. Conclusion : These findings suggest that Korean version of DS14 is a valid tool for measuring the type D characteristics. Type-D characteristics can be suggested to predict adverse prognosis in patients with CHD.

Many computer vision algorithms are computationally expensive and require a lot of computing resources. Recently, owing to machine learning technology and high-performance embedded systems, vision processing applications, such as object detection, face recognition, and visual inspection, are widely used. However, on-devices need to use their resources to handle powerful vision works with low power consumption in heterogeneous environments. Consequently, global manufacturers are trying to lock many developers into their ecosystem, providing integrated low-power chips and dedicated vision libraries. Khronos Group-an international standard organization-has released the OpenVX standard for high-performance/low-power vision processing in heterogeneous on-device systems. This paper describes vision libraries for the embedded systems and presents the OpenVX standard along with related trends for on-device vision system.

이문수,송경헌,김경아,송봉근,이래연,Lee, Mun-Soo,Song, Kyong-Hun,Kim, Gyoung-A,Song, Bong-Keun,Lee, Rae-Yohn 배재대학교 자연과학연구소 1998 自然科學論文集 Vol.10 No.1

오존을 이용한 마직물의 표백효과를 연구하기 위하여 오존 발생 장치에 의해서 생성된 오존을 물에 용존시킨 오존처리액으로 마직물을 처리하였다. 마직물의 오존처리를 위하여 오존 발생기와 오존 용존조를 사용하였고, 표백 효과를 측정하기 위하여 오존으로 처리된 마직물을 Hunter의 백도, 인장강도, SEM사진을 측정하였다. 발생 오존의 농도는 전압이 높을수록, 원료 산소가스의 유량이 적을수록 증가하였다. 처리포의 표백효과는 오존의 순수 농도가 증가함에 따라 증가하였다. 처리포의 백색도는 처리온도가 $0-15^{\circ}C$, 처리시간이 20분일 때가 최적의 상태를 나타내었다. 처리포의 인장강도는 처리시간이 길수록, 온도를 높여줌에 따라 저하하였다. In order to study on the bleaching efficiency of flex fabrics, ozone which has been produced by an ozone generator, has been contacted with flex fabrics in water at various conditions. The equipments used for the ozone reatment of flex fabrics were the ozone generator and a liquor/ozone contactor. For the study of the bleaching efficiency on flex fabrics, the Hunter's whiteness, tensile strength, microscopic properties of the ozone treated flex fabrics were measured. The concentration of generated ozone was increased, as the voltage increase, flow ratio decrease and oxygen amount increase. The bleaching efficiency of ozone treated fabrics was increased with increasing the net concentration of ozone. The whiteness ozone of treated fabrics was found to be best when treated temperature was $0-15^{\circ}C$ and treated time was 20 min. The tensile strength of treated fabrics decreased as the treating time increased, and as the temperature raised.
