Renal angiomyolipoma is an uncommon benign tumor of the kidney that consists of smooth muscle, blood vessels and mature adipose tissues. The most common benign renal tumor associated with spontaneous non-traumatic perirenal hemorrhage is angiomyolipoma, because of high vascularity. The ultrasonographic and computed tomographic images are sufficiently characteristic to permit accurate preoperative diagnosis. We report 2 cases of renal angiomyolipoma with spontaneous perirenal hemorrhage which were managed with nephrectomy.

임난영,서길희 대한류마티스 건강전문학회 2001 근관절건강학회지 Vol.8 No.1

The aims of this study were to understand and to predict the determinent factors affecting the exercise behaviors and physical fitness by testing the Pender's revised health promotion model, and to help the patients with rheumatoid arthritis and osteoarthritis perform the continous exercise program, and to help them maximize the physical effect such as muscle strength, endurance, and fuctional status and mental effects including self efficacy and quality of life, and improve the physical and mental well being, and to provide a basis for the nursing intervention strategies. Of the selected variables in this study, the endogenous variables included the physical fitness, exercise score, exercise participation, perceived benefits of action, perceived barriers of action to exercise, activity-related affect(depression) and perceived self-efficacy, interpersonal influences(family support), situational factors(duration of arthritis, fatigue) and the exogenous variables included personal sociocultural factor(education level), personal biologic factor(body mass index), personal psychologic factor(perceived health status) and prior related behavior factors(previous participation in exercise, life-style). We analyzed the clinical records of 208 patients with rheumatoid arthritis and degenerative arthritis who visited the outpatient clinics at H university hospital in Seoul. Data were composed of self reported qustionnaire and mood of fitness score which were obtained by padalling the ergometer of bicycle for 9 minutes. SPSS Win 8.0 and Window LISREL 8.12a were used for statistical analysis. Of 75 hypothetical paths that influence on physical fitness, exercise participation, exercise score, perceived benefits of action, perceived barriers of action to exercise, activity-related affact(depression) and perceived self-efficacy, interpersonal influences (family support), situational factors(duration of arthritis, fatigue), 40 were supported. The physical fitness was directly influenced by life-style, perceived health status, education level, family support, fatigue, which explained 12% of physical fatness. The exercise participation were directly influenced by life-style, education level, past exercise behavior, perceived benefits of action, perceived barriers of action, depression and duration of arthritis, which explained 47% of exercise participation. Exercise score were directly affected by perceived self efficacy, BMI, life-style, past exercise behavior, perceived benefits of action, family support, perceived health status, perceived barriers of action, and fatigue, which explained 70%. Perceived benefits of action was directly influenced by BMI, life-style, which explained 39% perceived barriers of action were directly influeced by Past exercise behavior, perceived health status, which explained 7%. Perceived self efficacy were directly influeced by level of education, perceived health status, life-style, which explained 57%. Depression were directly influeced by past exercise behavior, BMI, life-style, which explained 27%. Family support were directly influeced by life-style, perceived health status, which explained 29%. Fatigue were directly influeced by BMI, life-style, perceived health status, which explained 41%. Duration of arthritis were directly influeced by life-style, past exercise behavior, BMI, which explained 6%. In conclusion, important variables for physical fitness were life-style, and variable affecting exercise participation were life-style Perceived self-efficacy of exercise was a significant predictor of exercise score. BMI, Life-style, perceived benefits of action, family support, past exercise behavior showed direct effects on perceived self-efficacy. Therefore, disease related factor should be minimized for physical performance and well being in nursing intervention for patients with rheumatoid arthritis, and plans to promote and continue exercise should be seeked to reduce disability. In addition, Exercise program should be planned and performed by the exact evaluation of exercise according to the ability of the patients and the contents to improve the importance of exercise and self efficacy in self control program, dedicated educational program should be involved. This study suggest that the methods to reduce the disease related factors, the importance of daily life-style, recognition of benefit of exercise, and educational program to promote self efficacy should be considered in the exercise behavior promotion and nursing intervention for continous performance. The significance of this study is also thought to provide patients with chronic arthritis the specific data for maximal physical and mental well being through exercise, chronic therapeutic procedure, daily adaptation and confrontation in nursing intervention

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.

본 연구는 정보교육 프로그램이 갑상샘암 수술 환자의 심리 및 신체적 불편감 감소에 미치는 효과를 검정하기 위해 실시된 비동등성 대조군 전,후 시차 설계의 유사 실험연구이다. 자료수집 기간은 2006년 6월 17일 부터 9월 19일 까지 3개월간 이었으며, 연구 대상자는 일개 종합병원에 갑상샘암 수술을 받기위해 입원한 환자 가운데 6월 17일 부터 8월 3일 까지 입원환자 29명을 대조군으로 하였고, 8월 5일 부터 9월 19일 까지 입원환자 30명을 실험군으로 하였다. 연구도구는 심리적 불편감을 측정하기 위해 Derogatis 등(14)이 개발한 ‘자기보고식 다차원 증상목록(Multidimensional Symptom Inven- tory)검사를 사용하였고, 신체적 불편감 측정은 McCorkle & Young(16)이 개발한 도구를 사용하였다. 본 연구의 결과는 다음과 같다; 1) 정보교육 프로그램을 받은 실험군은 정보교육 프로그램을 받지 않은 대조군에 비해 심리적 불편감 정도의 차이는 통계적으로 유의한 차이를 보이지 않았다(p= .135). 다만 ‘근심 걱정’요인에서 유의한 불편감 감소효과를 보였다(p= 0.49) . 2) 정보교육 프로그램을 받은 실험군과 정보교육 프로그램을 받지 않은 대조군은 두군 모두 신체적 불편감 정도가 사후 유의한 수준으로 증가함을 보였다(p= 0.90). 결론적으로 본 연구를 위해 만들어진 정보교육 프로그램은 갑상샘암 수술 환자의 신체적 불편감 감소에는 효과적이지 못하였으나 심리적 불편감의 근심걱정 요인을 감소시키는데는 효과가 있음을 알게 되었다. Objectives: This study was designed as a non-equivalent control group pre and post-test quasi-experimental study to examine the effects of education program using information on the psychological and physical discomfort of patients undergoing operation for cancerous thyroid glands. Methods: The study covered for three months from June 17, 2006 to September 19, 2006. The subjects of this study were selected from those patients who were admitted in one of the general hospitals in order to receive the operation for cancerous thyroid glands. They include 29 control group patients who were hospitalized during the period of Jun 17th to August 3rd 2006, and 31 experimental group patients who were hospitalized during the period of August 5th to September 19th, 2006, respectively. The instruments utilized for conducting this study includes the Multidimensional Self-Report Symptom Inventory test originally developed by Derogatis & et al. (1983) for measuring psychological discomfort. And for measuring physical discomfort, the tools developed by McCorkle & Young (1978) was utilized. Results: 1) Hypothesis 1 “The level of psychological discomfort of the experimental group who completed the information education program would be decreased comparing with that of the control group who didn't complete the program” was partly supported (Worry & Anxiety factor: p= .049). 2) Hypothesis 2 “The level of physical discomfort of the experimental group who completed the information education program would be reduced comparing with that of the control group who didn't complete the program” was not supported (p= -.90). Conclusion: The information program provided for this study was proved to be not effective for decrease physical discomfort of the patients undergoing operations for cancerous thyroid glands but proved to be effective for decrease the anxiety factor of psychological discomfort.

The steelmaking dust treatment process has been established through reducing volatilization method in rotary kiln. The more content of zinc in reduced pellets and basicity of pellet is in the range of 1.5~3.0, the more working time needed in rotary kiln, because of decreasing wall accretion. A portion of well forming kiln coating in the furnace is a fourth of the total length from the outlet. Constitutes on the furnace wall accretion composed of the mixtures such as Fe, FeO, Fe₂O₃, Fe₃O₄, ZnO and CaO-SiO₂system, and formation of kiln coating is decreased by adding coke ratio.

전영길,강현희 안성산업대학교 2002 論文集 Vol.33 No.-

A industrial development and the high level of industrial technology since the Industrial Revolution in 18th century result in the improvement of qualities of human's lives, while they bring about the shortage of natural resources and the destruction of environment. Today as qualities of human's lives are improved, a lot of consumers are concerned about the environment of the earth and these thoughts are expanded rapidly. Therefore this study is planed to search the desirable direction which Green Marketing should achieve, through the direct and practical cases of Green Marketing, which becomes the factors of threat and chance to enterprises, in the view of approaching of the environmental problems which let mankind realize the serious crisis. The meaning Green Marketing has as the survival strategy of enterprise is prior to all management strategy. The thing required in the situation like this is that the solution and means which can cope with the environmental pressure effectively should be developed and generalized. And then it should be able to realize the pursuit of the enterprise's profit with the result of environmental improvement. However, the basic solution of this environmental problem isn't solved only in endeavoring of enterprise. As the cooperating of each related subject and the social responsibility are required, Green Marketing is more and more important. As Green Marketing combines with consumers and government as well as enterprise unlike the existing marketing, if it has the strong will of environmental harmony, it can be the driving force enabled the environmental management of enterprise effectively. To enable the induction and development of Green Marketing, the construction of environmental management system and the environmental mind are stretched like a blood vessel to the system of enterprise and are managed synthetically. When this system is realized, the beginning of the environmental difference can be acquired.

정신분열병과 NMDA 수용체와 연관된 D9S158 유전적 표지자와의 연관성을 알아보기 위해 75명의 정신분열병 환자군과 87명의 정상대조군을 대상으로 중합효소연쇄반응을 이용하여 연합연구를 시행하여 다음과 같은 결론을 얻었다. D9S158 유전좌위에는 모두 8개의 대립유전자가 있었고, 각 대립유전자는 cytosine-adenine염기가 반복되는 217염기쌍에서 233염기쌍의 형태였다. 먼저 정신분열병 환자와 정상대조군의 대립유전자의 빈도를 비교해 본 결과 통계적으로 유의한 차이를 보이지 않았다(p〉.05). 환자군을 좀 더 동질적으로 만들기 위해 정신분열병의 가족력 유무, 음성 및 양성증상, 연성신경학적 징후, DSM-IV 임상아형에 따라 환자군을 나누어 대립유전자의 빈도를 비교해 본 결과, 특정 임상양상과 관련이 있는 대립유전자를 발견하지 못하였다. 결론적으로 본 연구에서는 D9S158 유전좌위와 정신분열병의 연관성을 입증하지 못하였으나 NMDA 수용체 유전자주위의 다른 표지자나 좀 더 유전적으로 동질한 환자군을 대상으로 한 추후연구가 필요할 것으로 생각된다. An association study with Korean schizophrenic patients(N=75) and normal controls(N=87) was performed to find the relationship between D9S158 polymorphism and schizophrenia using polymerase chain reaction. Eight different alleles of a dinucleotide polymorphism on D9S158 locus were observed in both group. When we compared the frequencies of alleles between schizophrenics and normal controls, there was no significant difference between two groups. To increase homogeneity of schizophrenic group, we divided schizophrenic group by clinical phenotypes such as family history, negative and positive symptoms(PANSS), soft neurologic signs(NES-K) and DSM-IV diagnostic subtypes. Then we compared the frequencies of alleles among subgroups of clinical phenotypes, and there were no significant differences between subgroups(p〉.05). Although our findings fail to provide an evidence of association between schizophrenia and D9S158 locus, further investigation of other loci that are linked to NMDA receptor gene may be needed in genetically homogeneous subgroups of schizophrenia.

A demand for the machining of aesthetic fuctional sculptured surfaces increased nowerdays owing to the adavnces in CAD/CAM technology. A comparative evaluation of machining performance is analyzed in this study between a conventional machining methodoly unsing ball endmill and a new strategy using flat endmill under the criterion of machining efficiency, and its quantitative results are used to scheme the further recommendable cutter paths for the machining of curved surfaces. A commercial CC-Cartesian method using at ?? 5.2 system is applied as a representative conventional machining methodology, and an another method named Steepest Directed Tree (a SDT mehod) is applied as a new methodology using flat endmill which is machining the curved surfaces along the steepest paths on them. The curved surface models are tested to prototype the practical workpieces, and it is investigated the evaluation criteria quantitatively, such as surface roughness, total length of cutter paths, fillet radius of uncut volume at intersection regions of material, cutting state, and the total machining time.
