Jehovah's Witness comprise a unique obstetric population. Their refusal of blood stems from an interpretation of a literal translation of the Bible, and it is this belief that puts them at an increased risk of morbidity and mortality if hemorrhage occurs. We report two cases of a Jehovah's Witness who bled massively due to obstetric hemorrhage, refused blood transfusion and had profound anemia. The patients were treated with recombinant human erythropoietin, parenteral iron and oxygen. And they were treated on an intensive care unit with intermittent positive pressure ventilation. We reviewed with literature considering the therapy for acutely anemic patients who refuse transfusion to decrease the duration of the most severe anemia.

In this paper, we present conference key authentication mechanism by employing an algebraic method on IMT-2000 environment To accomplish this, Symmetric Balanced Incomplete block design is applied for generating the communication key and then this key is distributed to participants Through this technique for creating a conference key and mutual authentications performed based on identification information, the communication protocol is designed The protocol presented minimizes the transmission complexity for generating a conference key On a special case the time complexity is O(v√v), where v is the number of participant. The security of the mechanism, which is a significant problem in the construction of Secure system, can be, proved as computationally difficult to calculate as factoring and discrete logarithms.

고식적 검사로 간외 전이를 진단하지 못한 원발성 간암 환자에서 간이식 전에 시행한 전신 FDG-PET의 역할

이원우,류진숙,양유정,김재승,여정석,문대혁,이승규 대한핵의학회 2002 핵의학 분자영상 Vol.36 No.6

목적: 원발성 간암의 치료를 위해 간이식이 시행되고 있으나, 8-54%의 환자에서는 이식 후 원격 전이로 인한 재발이 보고 되고 있다. 이 연구는 간이식 예정인 원발성 간암 환자들에서 고식적인 검사로 진단하지 못한 간의 전이 진단에 있어서 FDG-PET의 유용성을 평가하고자 시행되었다. 대상 및 방법: 2001년 8월 이후 본원에서 간이식을 계획하고 전신 FDG-PET을 시행한 환자 중, FDG-PET 검사 이전에 복부 초음파와 CT, 흉부 x선 검사와 CT, 골스캔 등의 고식적인 검사를 시행하여 전이의 증거가 없거나(n=22), 애매한 이상 소견이 있었던(n=4) 원발성 간암 환자 26명(남:여=23:3), 평균 나이 55.7세)을 조사하였다. FDG-PET에서 양성을 보인 결과는 조직 검사나 임상적인 추적 검사로 전이 여부를 확인하였다. 결과: 고식적 검사에서 애매한 이상 소견이 있었던 환자 4명 중 3명의 6개 병변이 FDG-PET에서 국소 대사 항진을 보였고, 전이로 확인되어 간이식을 시행하지 않았다. 이 중 5 병변들은 의심되지 않았던 부위에서 새로 발견된 것이었다. 다른 1명은 PET에서 음성 소견으로 간이식을 시행하였다. 고식적인 검사에서 전이를 의심할 만한 소견이 없었던 22명 중에서는 5명의 환자에서 7개의 간의 국소 대사항진 병변들이 FDG-PET에서 발견되었는데, 이들 줄 1명은 2 개의 전이 병변이 확인되어 간이식을 시행하지 않았다. 다른 4명의 환자들에서 보인 5개의 국소 대사항진 병변들은 양성병변으로 확인되었고 이 중 3명은 간이식을 시행하였다. 요약하면, FDG-PET으로 4명의 환자에서 고식적인 검사로 찾지 못하던 전이 병변을 찾아 불필요한 간이식을 피할 수 있었다. 모두 17명에서 간이식이 시행되었다. 간의 조직 검사 소견과 비교하였을 때 생존 원발성 간암을 진단하는 FDG-PET의 민감도는 55.6% (5/9)이었고, 특이도는 87.5% (7/8)이었다. 결론: FDG-PET 전신 스캔은 간이식 예정인 원발성 간암 환자들에서 이전에 시행한 고식적인 검사들로 진단하지 못한 전이 병소들을 추가로 진단하여 불필요한 간이식 수술을 줄이는데 기여할 수 있었다. Purpose: Liver transplantation (LT), one of the therapeutic options of primary liver cancer has been suffering from recurrence caused by metastasis in 8-54% of patients. This study was performed to investigate whether FDG-PET is useful for detecting hidden metastasis in LT candidates. Materials and Methods: Twenty-six patients (male:female=23:3, mean age 55.7 year) underwent FDG-PET. Their previous conventional diagnostic studies (CDS) like a abdomen US and CT, chest x-ray and CT, and bone scan were negative (n=22) or equivocal (n=4) for metastasis. Positive FDG-PET findings were confirmed by biopsy or clinical follow-up. Results: Among 4 patients with equivocal metastatic lesions on CDS, 3 had 6 hypermetabolic lesions on FDG-PET, which were confirmed as metastasis and subsequently LTs were cancelled. Of these, 5 lesions were initially negative on CDS. Remained 1 patient underwent LT with a negative FDG-PET result. Among 22 patients without metastasis on CDS, 5 had 7 hypermetabolic lesions on FDG-PET. One of these patients proved to have 2 metastatic lesions, and LT was cancelled. The other 4patients had 5 hypermetabolic lesions on FDG-PET, which were confirmed as benign lesions, and 3 patients of them underwent LT. In summary, FDG-PET was useful in avoiding 4 unwarranted LT by detecting unsuspected metastatic lesions on CDS. A total of 17 patients underwent LT. In comparison with pathology, the sensitivity and specificity of FDG-PET for detecting viable primary liver cancer were 55.6% (5/9) and 87.5% (7/8), respectively. Conclusion: FDG-PET can detect additional hidden metastasis and contribute to reducing unwarranted LT in the patients with primary liver cancer. (Korean J Nucl Med 2002;36;368-80)

Electronic check schemes are more efficient than electronic coin schemes with respect to computational costs and the amount of information exchanged, In spite of these, difficulties in making a refund reusable and in representing the face value of a check have discouraged its development. In this paper, a online electronic check system is presented, which solves the above problems. This system uses the partially blind signature to provide user anonymity and to represent the face value of a check. This partially blind signature is EC-KCDSA using ECC. Then this regards mobile terminals for using M-Commerce. The partially blind signature enables us to make the format of refunds and initially withdrawn checks identical and mobile. Thus, it allows refunds to be reused to buy goods without any limitations.

The autoimmune nature of idiopathic thrombocytopenic purpura(ITP) and Graves' disease has been well established. In both disease, circulating immunoglobulins are believed to be involved in the pathogenesis and transplacental transfer of both disease is the ultimate proof of the importance of the humoral mechanism involved. Because of the tendency of autoimmune disease to cluster in the same individual or members of the same family, simultaneous incidence of ITP and Graves' disease is to be expected. However, in clinical practice, it has been described only rare. Therefore, we report here the case of a patient suffering sequentially from ITP and Geaves' disease with the literature.

국제해운항만로지스틱스에 있어서 항만경쟁력의 평가에 관한 연구 : 계층퍼지분석법의 적용 An Application of Hierarchical Fuzzy Process

김진구,여기태,이종인 한국로지스틱스학회 2002 로지스틱스연구 Vol.10 No.2

본 연구의 목적은 국제해운항만로지스틱스에 있어서 근간이 되는 경쟁항만의 현황을 조사하고, 실제 경쟁을 주도하는 구성요소를 파악하며, 항만경쟁력 평가모델을 개발하고, 평가모델에 각 항만의 구성요소별 data를 투입하여 실제 경쟁능력을 파악하는 것이다. 연구의 방법론은 속성간 중복도를 고려하여 연산 할 수 있는 계층퍼지분석법(HFP : Hierarachical Fuzzy Process)을 도입하였다. 그리고, 연구의 범위는 급변하는 국제해운항만로지스틱스에 있어서 가장 관심의 대상이 되고 있는 동북아시아국가 및 동남아시아국가의 컨테이너항문 중 2000년 컨테이너 처리실적 상위 20위 내에 위치한 항만을 대상으로 하였다. 연구의 결과 싱가포르 항만이 연구대상지역에서는 가장 경쟁력이 뛰어난 것으로 나타났다. 향후 연구과제로, 본 연구의 항만경쟁력 평가기법으로 채택된 HFP방법에 있어서 엄밀히 고려하지 못한 다수의사결정그룹(Multiple Decision-Making Group : MDMG)의 해결을 위한 보완적 연구가 더 필요하다. The purpose of this study is to grasp the real competitiveness of ports in international shipping and port logistics, by 1) examining the status of competitive ports, 2) grasping the components that lead the actual competition, 3) developing evaluation models of port competitiveness, and 4) putting component data of each port into these same evalation models. The research method which was used in this study accounted for overlapping between attributes, and introduced the HEP(Hierarchical Fuzzy Process) method that can perform an operation. The scope of this study covers the top 20 Northeast and Southeast Asian ports with respect to container handling in 2000. This has direct competition in attracting cargo from East Asia. The results of this study showed that the competitive power of Singapore Port was the highest among the ports of East Asia. Derived from the empirical study, the attempt to grasp the real port competitiveness in dynamic port activities is the merit of this study, especially in the rapidly changing environments of international shipping and port logistics. In order to reinforce this study, it needs further compensative research because the HFP method adopted as an evaluation model of port competitiveness in this study was not strictly considered enough to solve the problems such as MDMG(Multiple Decision-Making Group).

This study was designed to order descriptive data for nursing intervention for relief of fatigue and pain, and to distinguish by the characteristic difference and the symptoms such as fatigue and pain on Ankylosing Spondylitis(AS), Fibromyalgia(FM), and Systemic Lupus Erythematosus(SLE) patients. The sample consisted of 92 Patients(AS 29: FM 30; SLE 33) who visited H-University Rheumatism Hospital in Seoul The data were collected by a structured questionnaire from May 1. 1999 to April 30, 2000. The results were as follows: Patients of 95% experienced fatigue in the last week and a fatigue score of three disease groups were above average. The fatigue score of FM patients was highest in the other disease, but which was not a statistically significant difference(F= 1.417. p=.248). The mean score of AS and FM patients in pain was higher than the SLE patients, and there was the statistical significance among the three groups on pain (F=8.239. p=.001). There wasn't a statistical difference among three groups on coping wtih pain(F= 1.451, p=.240). There wasn't any correlation between fatigue and pain in each disease (AS. r=.008. p=.966; FM: r=.328, p=.077: SLE: r=.237,p=.185). Therefore, morning stillness and pain management during sleeping is needed through good body alignment in the AS patients. Adequate rest for fatigue and multiple coping strategies for pain maybe basic nursing intervention in FM and SLE. According to their fatigue rhythm. a regular exercise program is needed for rheumatic disease because they complained of fatigue above average and their fatigue was repeated bettor and worse only during the one week.
