Abstract - In this thesis, we propose a QoS supporting method on wireless ad hoc-based active network for improving reliability. On the loss of route path, the existing DSR routing protocol has several problems with wireless network communication because of decease of data reception rate and increase of network load. The proposed method improves reliability of data transfer by using functions of active network. That is, by using functions of active nodes and active packets, the proposed method supports QoS with reservation transfer method that saves data packets on transfer at intermediate nodes with lost path and then re-transmit the packets after route reconfiguration.

Acute myocarditis complicating coronary vasospasm after smallpox vaccination is very rare complication that can be generally developed within less than 30 days after vaccination. Clinically and biochemically, this disorder is often mimic and highly suggestive of acute myocardial infarction. We report 21 years old man that had a history of a smallpox vaccination 3 weeks ago and prodromal symptoms(fever, malaise etc) a few days ago. hIe visited to our hospital because of abrupt onset of severe substernal chest pain, dyspnea and diaphoresis. At admission, electrocardiography was ST elevation in lead Ⅰ, aVL, V4, V5, and V6. The CK-MB level was 68 U/L, LDH level was 760 U/L, Troponin-Ⅰ was 24.64 ng/㎖, and Troponin-T was positive. 2D-echocardiograpy was normal left ventricular function, Clinically we presumed this disorder as acute myocardial infarction and we promptly performed the coronary angiography and revealed focal spasm in distal left coronary artery territory without critical stenosis in both coronary arteries. We diagnosed this disorder as coronary vasospam complicating acute myocarditis that is different with acute myocardial infarction, and we prescribed nitroglycerin and nifedipine. After discharge, he is now well without any symptoms and has been following up monthly at our outward department for 6 months.

Objective : To investgate patterns of serial serum interleukin-6(IL-6) concentrations after initial successful cardiopulmonary resuscitation, and to access differences in serum IL-6 concentrations in patients with Cerebral Performance Category(CPC, 1-2) and CPC(3-5) at the 5th day after cardiacpulmonary resuscitation(CPR). Methods : We studied prospectively 12 patients with spontaneous circulation after cardiopulmonary resuscitation. Venous blood samples were taken 2, 4, 12, 24, 48 and 72 hours after restoration of spontaneous circulation to measure serum IL-6 levels by the enzyme-linked immunosorbent assay. Results : Serum IL-6 concentrations in the severe neurolgically disabled group(CPC, 3-5) were significantly increased at 2, 24 and 48 hours after restoration of spontaneous circulation compared with the less neurolgically disabled group. Also, serum IL-6 concentrations in the severe neurolgic disabled group showed dual peak at 4 and 24 hours. Conclusion : Our study demonstrates significant increase of serum IL-6 in patients with CPC(3-5) after successful cardiopulmonary resuscitation and the significant correlation between early increase of serum IL-6 and poor neurologic outcome. It suggests that early increase of serum IL-6 can be used as a prognostic marker after successful cardiopulmonary resuscitation.

감염성심내막염에 의한 신경계 합병증은 색전성 뇌경색, 색전성 뇌출혈, 두개내 패혈성 동맥류, 뇌농양, 뇌막염등 다양한데 항생제 요법의 발달과 판막치환술에도 불구하고 그 빈도는 감소되지 않고 있다. 이 중 두개내 패혈성 동맥류의 파열에 의한 뇌출혈은 사망률이 80%로 치명적일 수 있어 조기 발견 및 적절한 치료가 필요하다. 저자들은 두통, 열감, 근육통 등의 증상으로 내원하여 감염성 심내막염으로 진단받고, 항생제 치료로 임상증세의 호전중에 심한 두통과 전신적 발작이 있은 후 갑자기 발생한 두개내 뇌출혈을 심장초음파 및 뇌 컴퓨터 단층촬영을 통하여 진단, 경험하였기에 문헌고찰과 함께 보고하는 바이다. The complications of infective endocarditis may involve any organ system ie, cardia, neurologic, vascular, dermatologic, and kidney. Extracardiac complications are usually caused by either embolization of vegetations or deposition of immune complexes. Neurologic complications remain a significant problem in bacterial endocarditis and have been reported to occur in up to 20% to 40% of cases of infective endocarditis. The various types of central nervous system disease seen in patients with infective endocarditis are cerebral embolism (with infarction or with intracerebral hemorrhage), intracranial mycotic aneurysm, seizures, brain abscess, meningitis, mental change, psychiatric disorder. Mycotic aneurysms are uncommon but not rare and are an important cause of local or systemic sepsis and acute hemorrhage following aneurysmal rupture. Cerebral mycotic aneurysms have been noted in 2∼10% of cases of bacterial endocarditis and account for 2.5∼6.2% of all intracerebral aneurysms. We have experienced a case of neurologic complication due to infective endocarditis in a 23 year-old female patient, who admitted to our hospital because of fever, chill, headache, myalgia. This case was diagnosed by echocardiography, brain computed tomography. The patient died of sudden intracerebral hemorrhage in the 53th hospital day despite intensive medical treatment. We report one case of intracerebral hemorrhage complicated with infective endocarditis.

According to the test results, it can be concluded that the reinforcement of CF were considerably effective in improving tensile strength, flexural strength and toughness of cement matrices compared to conventional cement mortar.

중국거주 조선족 여성의 영적 안녕정도가 정신건강에 미치는 영향

정성덕,이종범,김진성,서완석,배대석,박순재,주열,염형욱,김승원,김구묘,안영록,황대홍,표미자,조창열,정태길 영남대학교 의과대학 2004 Yeungnam University Journal of Medicine Vol.21 No.2

자아초월 정신의학이 체계화되면서 영성(spirituality)은 인성의 한 부분이라는 이론이 대두되었는데 이 영성은 정신건강에 큰 영향을 미친다고 했다. 인간의 성향 중 영적 안녕 정도를 파악하여 그 정도가 정신건강 중 허위성 경향, 정신병적 경향 및 불안과 우울 경향 등에 어떠한 영향을 미치는지를 조사하고저 본 연구를 실시하였다. 대상은 중국의 연변 조선족 자치구에 거주하는 여성 400명을 대상으로 하여 한국판 영적 안녕척도를 사용하여 영적 안녕정도를 파악하였다. 영적 안녕척도의 총점과 이 척도의 2개 하위 척도인 종교적 안녕과 실존적 안녕 척도 양자로 평가한 성적이 불안-우울통합척도와 정신분열증 척도 및 허위성 척도로 평가한 성적에 미치는 영향을 검증하기 위하여 상관관계분석 및 회기분석을 실시하였다. 그 결과는 다음과 같다. 1) 영적 안녕척도로 평가한 조선족 여성의 총점은 68.29로 한국의 기독교 여성이 평가한 100.65보다 훨씬 낮은 점수였다. 2) 불안·우울통합척도로 평가한 총점은 44.88로 연변노인이 평가한 점수와 일개지역의 한국농촌주민이 평가한 점수와 비슷한 결과였다. 3) 허위성 척도로 평가한 성적은 평균 74.57로 70점 이상이 86%(344명)이었으나 영적 안녕 성적과 허위성 성적 간에는 유의한 상관이 없었다. 4) 영적 안녕총점은 정신분열증 척도로 평가한 정신병적 경향에 유의한 영향을 미치지 않았으나 종교적 안녕하위척도의 성적은 정신병적 경향을 높여준데 비하여 실존적 안녕하위척도의 성적은 정신병적 경향을 낮게 해주었다. 5) 영적 안녕척도의 총점 및 두 하위척도인종교적 안녕과 실존적 안녕은 불안과 우울에유의한 상관을 보였는데 영적 안녕총점이 높을수록 불안·우울 총점이 다소 낮아지는 경향을 보였다. 6) 종교적 안녕 하위척도와 불안과 우울과의 관계는 종교적 안녕점수가 높을수록 불안과 우울을 각각 다소 유의하게 높여주었으며 이에 비하여 실존적 안녕하위척도와 불안과 우울과의 관계는 실존적 안녕정도가 높을수록 불안 및 우울점수는 유의하게 낮아졌다. 이와 같은 성적을 미루어볼 때 연변에 거주하는 조선족 여성이 평가한 영적 안녕정도는 정신병적 경향과 불안 및 우울에 유의한 상관을 보였으면 이 척도의 하위 척도인 종교적 안녕정도는 정신건강에 부정적인 영향을 미치는 반면 실존적 안녕정도는 정신건강에 긍정적 영향을 미친 결과로 평가되었다. 이러한 결과는 공산주의 사회에서 실존적 안녕은 긍정적인 가치관으로 평가되는 반면 종교적 안녕은 정신건강에 부정적으로 작용한 것을 입증해 주었다고 하겠다. Background: Spirituality has been an important part of Transpersonal Psychology and is believed to have a large effect on the mental health because it has been systematized. The aim of this study was to determine the level of spiritual disposition on human beings along with its effects on one's mental health. Materials and Methods: The study targeted 400 women residing in Youn-Gil city of JiLin Prov., which is a district of the Cho-Sun tribe in China. Their spiritual well-being was studied using the Spiritual Well-being Scale-Korean Version. The spiritual well-being scale consists of 2 sub-scales of religious well-being and existential well-being. The study was evaluated using a lie scale, psychotic trend, and a combined anxiety-depression scale. The results were considered to be factors of one's mental health. The correlation between the spiritual well-being and each tendency was analyzed by regression analysis. Results: The total score of the Cho-Sun tribal women according to the spiritual well-being scale was 68.29 which was much less than the 100.65 of Korean Christian women. There was no significant correlation between the spiritual well-being and the Lie trend. However, it was found that 86%(344) of Cho-Sun tribal women scored above 70 in the Lie trend with a mean score of 74.57 which is higher than normal populations. Regarding the correlation between the spiritual well-being and psychotic trend, the psychotic trend became significantly higher when the religious well-being was at a high level. On the other hand, the psychotic trend became significantly lower when the existential well-being was at a high level. Regarding the correlation between the spiritual well-being and anxiety, the anxiety was significantly higher when the religious well-being was at a high level. However, the anxiety level was significantly low when the existential well-being was at a high level. Regarding the correlation between the spiritual well-being and depression, the depression level was somewhat significantly high when the religious well-being was at a high level. However, the depression level was significantly low when the existential well-being was at a high level. Conclusion: This study evaluated the effects of spiritual well-being on a person's mental health among Cho-Sun tribal women in Youn-Gil city of JiLIn Prov., P.R. of China. The results found that the religious well-being, which is a sub-scale of spiritual well-being, had negative effects while the existential well-being had positive effects on the mental health. These results proved that a person's religious disposition had negative effects on their mental health in a communitarian society.

This research aims to prove that relaxation practice that includes abdominal breathing and progressive relaxation is an effective method in lowering the blood pressure by comparing·approving the effect on state anxiety and the blood pressure, which was proceed to divide middle-aged women into relaxation practiced group, aerobic trained group and controlled group randomly and to compare each group and the period of measurement with the data of state anxiety and blood pressure were measured before the test, during the test and after the test under rest from the program was performed for 4 weeks. The research was carried out from Aug. 05 to Sep. 06, 2002 with the measurement that includes the test of 2 times of high pressure under rest for one week to the subject of 21 persons of woman hypertensives from forties to sixties who reside in Busan and then, with the instruction of abdominal breathing and progressive relaxation 2 times a week to the relaxation practiced group, the instruction of aerobic exercise 3 times a week for 4 weeks to aerobic trained group and non-instruction to controlled group. 2 weeks after the test, state anxiety and blood pressure were measured and post investigation was made after then. For the process of data using SPSS Program 10.0, repeated measure ANOVA was used at significant level p=.05 in the comparison of each group and the change of relevant variable, one-way ANOVA was used in the analysis of the period of the test among each group and multiple comparison by Tukey test was made in the post approval. From this process of date, the following conclusion was drawn. First, state anxiety of relaxation practiced group was decreased significantly in comparison to that of aerobic trained group and controlled group. Second, the systolic blood pressure of relaxation practiced group was decreased significantly in comparison to that of aerobic trained group and controlled group. Third, the diastolic blood pressure of relaxation practiced group was decreased steadily in comparison to that of aerobic trained group and controlled group, but statistical significant decrease was not found Consequently, its been proved that the relaxation practice which consists of abdominal breathing and progressive relaxation didn't affect on the diastolic blood pressure but did affect on the control of state anxiety and the systolic blood pressure.

The purpose of this study was to investigate current situations on middle school physical education(PE) teacher's health instruction in Kangwon-do. The results attained from 165 middle school physical education teacher's in Kangwon-do are listed below: 1.Although physical education recognize the absolute necessity of health instruction in middles schools in Kangwon-do, it can't be acknowledged that sufficient instruction is being performed due to numerous other reasons. 2.Mostly, physical education teachers are in change of health instruction, but sometime it is refered to nurse-teachers, 3.For appropriate health instruction, first of all, related teaching materials and training opportunities should be more available. Based on above conclusion, following suggestions are made: 1.Information about health instruction must be sought with a great weight when teachers have any training opportunity. 2.School classroom must equip necessary teaching materials for health instruction. 3.There have to be more opportunity for intensive training to teachers. 4.Health instruction includes subtle subjects like problems relates sex education. Physical education teachers be in change of course but it can asked to nurse teachers if it for a better quality of health instruction.(It should be more rational to request nurse-teachers if a young male physical education teacher is in a girl's school) Also, issues related to independence on health instruction subject must be carefully examined.
