Hypoparathyroidism is usually the result of an inadvertent surgical removal of all the parathyroid glands, In some instances, not all the tissues are removed, but the remainder undergoes vascular supply compromise secondary to the fibrotic changes in the neck after surgery, Previously, the surgery for hyperthyroidism was the most frequent cause of acquired hypoparathyroidism. Idiopathic hypoparathyroidism is a relatively rare disease that is characterized by hypocalcemia and hyperphosphatemia due to a parathyroid hormone deficiency of an unknown cause, It usually develops at a young age, and shows various clinical symptoms and signs accompanied with hypocalcemia. In addition, it is rarely associated with polyglandular autoimmune syndrome during the follow-up. Hypocalcemia and idiopathic hypoparathyroidism associated with labor and lactation are rarely reported condition previously. We here describe a case of a woman in whom the symptomatic severe hypocalcemia appeared after her delivery. We reviewed all the previously reported cases and suggest a possible physiological explanation for the association between pregnancy, lactation, and the appearance of symptomatic hypocalcemia.

Recently, the information exchange through a communication network has been increased rapidly. When the sensitive information being sent or stored, the cryptographic technique can be employed in order to prevent it from being exposed or modified by the illegal third party. To implement public key encryption systems based on the integer factorization and the discrete logaritm problem, an efficient exponential arithmetic is mandatory due to large numbers involved. In this paper, the general analysis about the high­speed implementation of primality testing and exponentiations are investigated as well as implementing RSA public­key system. The public­key cryptosystem can be applied to any applications which need both the privacy and the authentication. Finally, suing the software package named MIRACL which provides the basic number theoretic routines for cryptographic software developers. we have implemented the RSA encryption and decryption with Blum­Goldwasser probabilistic algorithm under various key and message size.

Background : Coronary disease is highly prevalent in patient with end stage renal disease (ESRD) and account for much of their observed morbidity and mortality. Troponin-I consistently maintains a high sensitivity and specificity and is most sensitive marker for ischemic heart disease (IHD). Method : We examed 49 hernodialyzed patients (22 male, 27 female) without evidence of acute coronary syndrome (ACS) for 6 months. Biochemical markers were measured in serial predialysis blood samples. For analysis, we used two cardio-specific assays for troponin-T (cTnT) as well as for troponin-I (cTnI) and compared the results with CK-MB (reference value ≤ 4.0 ng/mL) concentration. Results : Myocardial ischemia was observed in 47% (23/49) of patients. cTnT level above 0.1 ng/mL. and cTnI level above 0.5 ng/mL, were observed in 22% (11/49) and 20% (10/49) of patients respectively. cTnI revealed significantly higher positive rate in patients with myocardial ischemia than the patients without myocardial ischemia (43 % vs 30%) (p<0.05). cTnT and CK-MB revealed no difference in positive rate between the patients with and without myocardial ischemia (cTnT : 30% vs 15% and CK-MB : 30% vs 19%). The sensitivity and specificity of cTnI to myocardial ischemia were higher than those of cTnT and CK-MB (sensitivity 43% vs 30% and 30%. specificity 100% vs 85% and 81%). Conclusion: Both cTnT and cTnI are useful in ruling out myocardial injury in chronic renal failure patients. But. cTnI is a more sensitivity and excellent specificity of ischemic heart disease than cTnT and CK-MB in hemodialyzed patients. In patients with ischemic heart disease, the presences of DM and advanced age were higher than those in patients without ischemic heart disease (p<0.05). Among the baseline characteristics old age, elevated LDH and diabeties were significant more frequent in the patients with elevation of cardiac troponin-I (p>0.5 ng/mL) than those with cardiac troponin-I (p<0.5 ng/mL), p=0.038, p=0.049, and p=0.045, respectively. Our results suggest that these cTnI is the potential diagnostic marker for the prediction of IHD in ESRD patients.

A retrospective study of operative results were carried out in a series of 164 patients who were performed microdiscectomy and 57 patients performed automated percutaneous lumbar discectomy (APLD) for herniated lumbar discs between January 1, 1990 and June 30, 1996 at the Department of Neurosurgery, Soonchunhyang University Hospital. The operative results were analysed, and the correlation between preoperative clinicoradiological factors and postoperative clinical results were statistically assessed. The major results were as follows : 1. Of 164 microdiscectomy cases, 102 were males and 62 were females, mean age was 42.4 years and incidence was the highest in the 5th decade, and of 57 APLD cases, 43 were male and 14 female, mean age was 32.2 years and incidence was the highest in the 3rd decade. 2. The preoperative symptoms and signs were lumbago(98.2%), radiating pain(96.3%), positive straight leg raising test(77.4%), motor weakness(27.4%), claudication(13.4%) & voiding difficulty(2.4%) in microdiscectomy cases, and lumbago(98.2%), radiating pain(98.2%), positive straight leg raising test(70.2%) & motor weakness(17.5%) in APLD cases. 3. Number of operated levels were performed 226 in microdiscectomy and 74 in APLD. The most commonly operated levels of two groups were L4-5 level. 4. Operative results 1) The overall success rates by Prolo's scale were 87.1% in microdiscectomy and 80.7% in APLD, respectively. 2) In younger age group (below 30 years) and in non-compensatory group, success rates were significantly higher in microdiscectomy. 3) As to protrusion and degeneration on MRI, clinical results of moderate protrusion and degeneration of discs in microdiscectomy were statistically significant, and those of mild protrusion and degeneration of discs in APLD were also statistically significant. 4) The most common cause of failure was inappropriate removal of disc material in microdiscectomy and sequestered discs in APLD. According to the above results, there were no differance in overall success rates between microdiscectomy and APLD. But clinical results seem to be influenced by the age, existence of compensation, and by the degree of protrusion and degeneration of discs as prognostic factors. If the selection of operative procedure between microdiscectomy and APLD for herniated lumbar disc is carefully done with clinical and radiologic findings of patients, good outcome might be achieved.

항공기용 단순싸이클식 공기냉동기의 작동성능 모사

김범신,부준홍 한국항공대학교 1997 論文集 Vol.35 No.-

최소한 제한된 용도의 범위에서 공기압축식 냉동싸이클(ACM)의 성능을 전형적인 증기압축식 냉동싸이클의 성능과 비교될 만큼 향상시킬수 있는 가능성이 검토되었다. 몇가지 종류의 ACM중 단순식 싸이클을 연구대상으로 선택한 이유는 장치구성이 간단하고 경량이며 제조비용이 상대적으로 저렴하기 때문이다. 선정된 시스템의 성능을 모사하기 위해 수치적인 절차가 수립되었으며 각 주요 구성요소의 성능과 관련된 변수들을 고려하기 위해 수치 프로그램에 적절한 방정식들이 이용되었다. ACM의 성능계수와 냉각효과를 향상시키는 중요한 인자는 엔진에서 추가되는 블리드 공기의 온도와 압력이다. 충분히 낮은 온도와 높은 압력으로 bleed air가 ACM에 공급된다면 그 성능은 증기압축식 시스템의 성능과 비교될 수 있다. 더우기 시스템의 성능은 터빈의 팽창과정전 열교환기의 거동에 거의 비례한다. 따라서 별도의 압력용기를 이용하여 터빈으로 유입되기전 냉매공기를 냉각시킬 수 있다면 시스템의 냉각효과는 향상되리라 기대된다. An air-cycle machine(ACM) was investigated for the possibility of improving its performance to a comparable level, at least in a limited range of usage, with the conventional vapor-compression type refregeration system. A simple-cycle system was studied among several types of ACM for its brevity in structure, light weight and low manufacturing cost. A numerical procedure was established to simulate the performance of the selected system. Appropriate equations were incorporated into a computer program to account for associated performance variables in each major component: heat exchanger, fan, and turbine. The major factors for improving the coefficient of performance and the cooling effect of the ACM were identified as the temperature and the pressure of the inlet bleed air from the engine. Provided that some means are adopted to lower the temperature and to increase the pressure of the bleed air, the simple-cycle ACM may exhibit a comparable performance with the vapor compression system. In addition, the system performance showed almost proportional behavior to that of the heat exchanger prior to the turbine expansion. Use of a separate pressure tank which allows the compressed air to cool down before expantion is suggested to enhance the cooling effect.

Robert Frost의 노동의 시학

김신범 한국현대영미어문학회 2000 The Journal of KACELLS Vol.5 No.-

The purpose of this study is to examine Robert Frost's poetics of labor, derived from extreme human situations. While not a particularly innovative approach, viewing art in its relation with life is nevertheless a crucial method of Robert Frost scholarship. Frost was concerned with the universal and enduring emotions, that highlight contemporary life in the 20th century. In other words, like many other contemporary poets, Frost did not think that man can live fantastically or romantically amid the harsh realities of the world. Therefore, his poetry is focused on the methods for accepting and overcoming these tragic problems. In Frost's own words, the purpose for writing poetry is "a momentary stay against confusion." Therefore, the main theme of his poetry was the wisdom of coping with the human existential situation-chaos or confusion. Frost has shown that man is not doomed to frustration and failure. The fact that he exploits terrifying aspects of human life for his poetic materials seems to suggest that he accepted the vision of doom in life. New England was an archetype for his poetic world. In other words, New Englanders served as models for his poetry writing. Frost himself once said about metaphor, "Poetry begins in trivial metaphors, pretty metaphors, "grace" metaphors, and goes on to the profoundest thinking that we have. Poetry provides the one permissible way of saying one thing and meaning another." In sum, Frost's composition of poetry is focused his metaphors. Therefore, Frost in his poetry begins with a realistic description of a scene or matter and develops into an interpretation of its meaning. Throughout his creative career, Frost exhibited painstaking and consistent efforts to overcome these tragic human existential conditions. In the face of chaos and the uncertainty of life, endurance and acceptance are sometimes essential; however, for the sake of survival, man should fight against the tragic conditions with effort, wisdom, courage, and a profound meditation on life. Accordingly this study examines the metaphor of labor among some disorderly and chaotic aspects of life. Frost believed that laboring and writing is the same in the light of the purpose. And the crux of his poetics is made up the thought. In conclusion, as Frost states in "The Lesson for Today," "I had a lover's quarrel in the world." He proposed courage and wisdom in enduring the calamities of life, and love born of genuine human relationships. In this respect, he is a great poet who strove to achieve man's self-recognition through the various conflicts and chaotic facets of life and to show unity through acceptance and conquest. This lover's quarrel is Frost's poetic subject, and throughout his poetry there are evidences of this view of man's existence in the natural world.
