Regulation of Ca^++ channels across cell menbranes can be dramatically altered by ischemic states, and such agents relates to cytotoxic effect. The genration of free radicals in ischemic tssue is detrimental to survive of that tissue. If intracellular calcium increasement and free radical production can be blocked or scavenged, tissue damage should be minimized. In the concept of above theory, the author studied the effect of nifedipine. α-tocopherol known as a calcium channel blocker and hydrohobic scavenger on the random pattern skin flap survical of white rats . Sprague-Dawley rats(N-60) were divided into four groups of control(no medication) , nifedipine(10㎎/ ㎏ /day, I.M.), α-tocopherol(20㎎/㎏/day, I.M.). nifedipine plus α-tocopherol. All of medications were given for 11days from 4days before flap elevation and contnued for 7days after flap elevation. When flap survival rates were measured. Flap tissue was obsered by gross, light microscooc and electron microscopic levels. The results were obtained as follows. 1. Groups treated with nifedipine. α-tocopherol. nifedipine +α-tocopherol showed significant increase of the area of flap survival compared with that of the control group.(P<0.001 in nifedipine group and α-tocopherol, and P<0.01 in nifedipine plus α-tocopherol group.) 2. The flap survival was best improved in the α-tocopherol group. (P>0.05). 3. Skin including dermis after 3 days of Nifedipine plus α-tocopherol group disclosed marked proliferation and dilatations of vessels in the deeper part. 4. Electron micrograph of endothelial cells after 3 and 5 days of Nifedipine and α-tocopherol groups disclosed intact basement membrane, swelling of endoplasmic reticulum and mitochondria. Following the above results. It is suggested that calcium channel blocker and α-tocopherol seem to play a important role which incerase survival of the skin flap.

Objectives : The aim of the study was to assess the hitologic appearance according to endometrial thickness in postmenopausa endometrial fluid accumulation women. Methods : A group of 20 postmenopausal women with an endometrial fluid accumulation confirmed by ultrasonography and underwent Dilatation & Curettage. The patients were divided into two groups according to the endometrial thickness(ET). Sixteen women had thin endometrium (<4mm) and four women had the thick endometrium (≥4mm). Results : When ET was ≥ 4mm, proliferative endometrium was found in 2 patients (50%), atrophic endometrium was in I patient (25%) and endometritis was in I patient (25%). When ET was < 4mm, atrophic endometrium was found in 14 patients (87%), A majority of patients with ET of less than 4mm in ultrasound had atrophic endometrium. The incidence of intrauterine pathology increased with the increasing thickness of endometrium as abserved by ultrasound. Conclusion : The presence of endometrial fluid accumulation in postmenopausal patients without any symptoms seems to be a benign condition. Normal endometrium of less than 4mm observed by ultrasound in postmenopausal women without vaginal bleeding dose not necessarily need further surgical investigation.

Brand Identity 설정을 위한 Visual Design의 역할

윤홍열 남서울대학교 2002 남서울대학교 논문집 Vol.8 No.-

The meaning of 'brand' is highly valued these days, since it contains the quality and reliability of products. The brand includes more than the set of various features such as the names, logos, specific designs and colors. It is now considered as a 'contract of trust' between the company and its shareholders including customers, investors, employees and the public. The success or failure of a brand depends on how customers view the products and on how these views are capitalized into their purchase, use and repurchase. The sole goal of branding is thus to differentiate one's products and service from others' and let the customers to recognize their unique and outstanding quality. In the modern society, customers move away from technical consumption. The trend of consumption can be characterized by a marked individuality and personality. They now buy products for their and entertainment. The intention of manufacturers is to decrease the influencing power of price and achieve competitive advantage by creating 'brandized products' rather than simple 'commodities'. In the current environment where customers' taste varies and the mass media plays an enormous role in marketing, it is essential that a company establish a systematic design strategy for its brands to secure competitive advantage against competitors. Strategic marketing positioning that uses powerful designs of a power brand is called for in order to achieve a higher market share and competitive advantage.

호르몬 불응성 전립선암 환자에서 mitoxantrone과 prednisone의 병합화학요법 후 통증완화 및 삶의 질 측정

이홍우,이지열,김세웅,이충범,강성학,조용현,황태곤,박용현,윤문수 대한화학요법학회 2000 대한화학요법학회지 Vol.18 No.3

목적 : 호르몬 불응성 전립선암 환자의 생명을 연장시키는 치료법은 현재로는 없으며, 현 시점에서의 치료목표는 증상의 경감 및 소실에 따른 삶의 질 향상에 두고 있다. 호르몬 불응성 전립선암의 고식적인 치료에 일차적인 치료법으로 간주되는 mitoxantrone과 prednisone의 화학요법이 호르몬 불응성 전립선암 환자의 통증완화 및 삶의 질에 어떠한 영향을 미치는지 알아보았다. 방법 : 1998년 7월부터 1999년 12월까지 증상이 있는 18명의 호르몬 불응성 전립선암 환자를 대상으로 하였으며, 일차적인 치료의 목표는 환자 본인이 기록하는 McGill-Melzack 6단계 통증척도에서 진통제의 증량 없이 2점이 감소(또는 첫 점수가 1점일 경우 통증의 완전소실)하는 것으로 하였다. 이러한 기준은 최소 3주 간격으로 시행한 자가 기록조사에서 연속적으로 2번 이상 유지될 때 유효한 것으로 간주하였다. 건강과 관련된 삶의 질 측정은 전신적 치료의 임상적 응용을 위한 실제적인 측정방법으로 개발되어 환자가 직접 작성하는 전립선암 특이성 삶의 질 측정기구(Prostate Cancer-Specific Quality-of-Life Instrument : PROSQOLI)의 비례연속형의 자가측정 척도(linear analogue self-assessment scale : LASA)를 이용하였으며, ECOG performance status를 사용하여 전신상태의 변화도 측정하였다. 결과 : 통증의 경감으로 나타나는 고식적인 치료의 반응은 66.7%(12/18)에서 나타났으며, 반응의 지속기간은 2개월에서 10개월까지로 평균 4.2±3.6개월이었다. PROSQOLI로 측정한 삶의 질은 통증에 대한 고식적인 치료반응을 보인 12명(66.7%) 모두가 삶의 질이 개선되었으며 특히 통증, 변비, 소변보기, 전반적인 복지상태에서의 유의한(p<0.05) 증가를 보였다. 치료 후 혈장 PSA 수치는 고식적인 반응의 유무에 관계없이 별 다른 변화를 보이지 않았으며, 골주사 또는 전산화 단층촬영으로 측정한 방사선학적 병변은 고식적인 반응을 보인 2명을 제외하고 치료 전과 비교하여 차이를 보이지 않았다. 병합 화학요법과 관련된 특별한 부작용은 관찰되지 않았다. 결론 : 통증을 동반한 호르몬 불응성 전립선암에서 mitoxantrone과 prednisone의 병합화학요법은 66.7%의 환자에서 통증의 감소 및 삶의 질이 향상되었다. 현재는 혈장 PSA 수치, 병소의 크기나 개수등이 치료의 지침이나 치료결과의 판정을 위한 객관적인 기준으로 사용되는 경향이 있지만, 앞으로는 환자를 중심으로 통증을 포함한 삶의 질 측정이 고식적 치료 후 치료결과 판정에 있어 객관적이고 적절한 방법이 될 것이다. Background : There is no evidence that therapeutic modalities prolong the survival of patients with hormone-refractory prostate cancer nowadays. The main goal of treatment is therefore improvement in quality-of-life including palliation of symptoms. We performed this study to investigate the benefit of mitoxantrone and prednisone chemotherapy in patients with symptomatic hormone-refractory prostate cancer using relevant end points of palliation regarding to pain and quality-of-life. Methods : From July 1998 to December 1999, we assessed the 18 patients with symptomatic hormone-refractory prostate cancer receiving mitoxantrone and low dose prednisone. The treatment end point was a palliative response defined as a 2-point decrease in pain assessed by a 6-point pain scale complemented by patients (or complete loss of pain if initially 1+) without an increase in analgesic medication and maintained for two consecutive evaluations at least 3 weeks apart. Health-related quality-of-life was evaluated with a series of linear analogue self-assessment(LASA) scale of the Prostate Cancer-Specific Quality-of-Life Instrument (PROSQOLI) and performance status was also measured. Results : Palliative responses were observed in 12(66.7%) of 18 patients. The duration of palliative responses were 4.2±3.6 months(range: 2 to 10 months). Treatment was well tolerated without specific side effects. There were no differences in prostate-specific antigen (PSA) level following treatment and no significant changes of radiologic findings evaluated by bone scan and/or CT were noted except 2 cases after chemotherapy. All the responding patients had an improvement in quality-of-life scales and performance status, however serum PSA levels were not changed. Conclusions : Chemotherapy with mitoxantrone and prednisone provides palliation and an improvement in quality-of-life for more than half (66.7%) of the patients with symptomatic hormone-refractory prostate cancer.

대형 건물에서의 화재시 연기 거동 및 거주자 피난에 관한 수치해석 연구

최상열,유홍선 중앙대학교 미래신기술연구소 2003 미래신기술연구소 논문집 Vol.12 No.1

본 수치해석 연구는 대형 건물에서의 화재 발생시 화재공간 내부의 온도장 및 연기거동을 해석하고, 거주자들의 피난을 모사하기 위해 FDS 코드와 SIMULEX 프로그램을 각각 사용하여 수행하였다. 서울의 대형 OO 빌딩의 지상 19 층과 지하 2 층을 해석 대상으로 하였으며, 초기 화재의 발생은 Fast 화재 성장모드로 가정하였고, 거주자의 다양성을 적용하여 피난을 해석하였다. 화재 발생 후, 지상 19 층의 경우 4 분여가 경과하면 국부적으로 천장 온도가 300 도 이상으로 상승하는 부분이 발생하게 되고, 사람의 키 높이 정도에서 가시거리가 5m 이하로 나타나게 되어 피난에 장애를 초래하는 것으로 나타났다. 지하 2 층의 경우는 아트리움의 영향에 의해 연기가 전체 공간으로 퍼져나가지 않았으며, 1.8m 정도의 높이까지 연층이 하강하는데 걸리는 시간은 약 5분 정도가 소요되었다. Smoke movement, temperature field, and evacuation of occupants in the nineteenth floor and the second floor underground of a large building on fire are studied. FDS code and SIMULEX program are used for the analysis of smoke movement, temperature field and evacuation of occupants, respectively. Fire growth mode is assumed as 'Fast' in the initial fires, and people characteristics are considered to account for the various evacuation feature. In case of fire on the nineteenth floor, after 4 minutes have passed, the region where the ceiling temperature is above 300℃ locally appears and visibility distance at the height of an adult becomes below 5m. This visibility distance causes the difficulty in people's evacuation. In case of a fire on the second floor underground, smoke did not spread over the whole area due to the geometry of atrium and it takes 5 minutes for the smoke layer move down to 1.8m vertical distance.

기독문서 선교와 일러스트레이션의 기호적 영향에 대하여

윤홍열 남서울대학교 1996 남서울대학교 논문집 Vol.2 No.-

Nowadays nobody is free from the influence of the new media, directly or Indirectly. Overflowing information provided by this new media confuses the recipient's critical standards. This phenonmenon is the case in the Christian missionary work. Accordingly there is an urgent need for the visual media which satisfies the function and role of missionary work for each target group. That is, for the efficient implementation of missionary work in the long run, the visual media to which more people can respond must be developed. As one form of the visual expression, illustration can provide communicational function, artistic effect, and even creative expression. The purpose of this paper, therefore, is to reconsider the impact of illustration in the field of missionary work.
