곽호영,한정현 제주대학교 1992 논문집 Vol.35 No.-

This paper deals with instruction scheduling, one area of compiler optimization. This assures the correctness of program execution during occuring the interlock and reduces the execution time in pipelined processor. DAG(Directed Acyclic Graph) is used to represent the problem and is proven to be pretty convinient to represent the various Kinds of serialization constraints. Gibbon's scheduling algorithm with O(n²) is introdued to schedule the instruction from DAG. Three heuristics and some assumptions are explained to prevent the problem to be O(n⁴). Furthermore, the impact on another phase in compiler is discused. Actually this scheduling algorithm assumes to perform the instruction scheduling after register allocation. More work relating to this area will be the relationship beween two phases-register allocation and code schduling.

The incidence of double primary cancer is about 10% in all kinds of cancers. Double primary cancer is usually accompanied by gastrointestinal cancer. Esophageal cancer is supposed to be frequently accompanied by squamous cell carcinoma of the head and neck or the upper respiratory tract, because of such common carcinogens as smoking and alcohol ingestion. Esophageal cancer and hypopharyngeal cancer are usually diagnosed by esophagogastric endoscopy with biopsy. We performed endoscopic ultrasound-guided Trucut biopsy(EUS-TCB) to diagnose a mediastinal mass in a 49 year-old patient, who visited our hospital because of voice change. During procedure, we accidently found enlarged celiac lymph node, and obtained tissue from the mediastinal lymph node and the celiac lymph node. We confirmed double primary cancer of squamous cell carcinoma in the esophagus and the hypopharynx via esophagogastric endoscopy.

The authors present two cases of solitary thalamic abscess which were intially diagnosed as malignant thalamic glioma. After treatment with steroids and osmotic agents, the patients' clinical conditions improved after two to three days. However, sudden deterioration of consciousness level developed and the CT scan showed acute hydrocephalus with increment of thalamic low-density lesions. We performed extraventricular drainage and obtained CSF containing numerous inflammatory cells. This suggested the possibility that the lesion was a pyogenic abscess. which progressed to ventriculitis, rather than a malignant glioma. Stereotactic aspiration of the lesion confirmed thalamic abscess. These findings and review of previous reports of thalamic abscess suggested that early diagnosis and stereotactic drainage of the thalamic abscess is of primary importance.

레이저를 이용한 얇은 원통형 튜브에서의 유도초음파 발생

레이저를 이용하여 두께가 얇은 원통형 튜브에 유도초음파를 발생하고, 공기-결합 트랜스듀서를 이용하여 비접촉식으로 수신하였다. 원통형 튜브는 발전설비의 열교환기 및 증기발생기 튜브에 사용되는 인코넬(Inconnel)튜브이다. 레이저의 조사 경로에 선 배열 슬릿을 삽입하여 유도 초음파의 파장을 조절하였다. 파장이 일정할 때 발생되는 모드를 이론적인 분산선도로부터 예측하고, 예측된 위상속도로부터 공기-결합 트랜스듀서의 경사각을 결정하였다. 원통형 튜브에는 축대칭 모드가 지배적으로 발생하는 것으로 나타났다. 이러한 결과는 웨이블렛 변환에 의한 시간-주파수 선도와 이론적인 분산선도를 비교한 결과 증명되었다.

Problems of wastes that pigs produce are increasing rapidly in the hog raising industry nowadays. consequently, the generation volume of excreta also is increasing but most of that is not disposed appropriately and exposed in eco-system therefore the disposal of stock excreta is becoming more and more serious. considering the physical and chemical characteristics of livestock excreta, the pollution loading rate - BOD, COD etc. - is very high. as alternative plan, that is, as one method kind of composisting, the utilization of the soil reformation agent will become one solution in managing the upper problems. also, the flyash of 3.7 million tons are producing every year and about 32.2% of that, 1.18 million ton is recycled as concrete, cement, cementassistance, road etc. consequently, the discharged flyash is not abandoned and a plan of recycling is needed acutely. gypsum of 4.16 million tons in 1998 presently was produced and about 57.2% of that, 2.38 million tons was recycled as cement, construction materials. the present stock is 25 million tons. therefore, in this study, because organic materials can be obtained in pig excreta and calciums can be obtained in gypsum, the small amount of elements can be acquired in flyash for the soil reformation agents, mixing the three materials - pig excreta, gypsum, flyash - adequately, investigated technique of making the soil reformation agents and described below in comparrision with the changes of temperature, PH TOC, T-N, TOC/T-N ratio etc.

고속 컴볼류션을 이용한 영상 복원에 관한 연구

This paper is intended as an introduction to the principles and computer simulation of parallel beam image reconstruction which may be classified as radon transform and circular convolution. The radon transform is a mapping from two dimensional image domain to a parameter domain. Therefore, high speed and data compression has been obtained. The radon transform leads to the projection or central slice theorem through a one dimensional or two dimensional fourier transform. The inverse radon transform can be implemented by filtering the projections in the fourier domain and back-projection. Circular convolutions are usually evaluated via FFT(fast fourier transform). The fast convolution advantages of this technique are that it is more efficient than the well-known fourier transform.

동양사상을 통한 태권도정신 정립을 위한 연구

Taekwondo which is a traditional martial art native to Korea, is well-Known throughout the world at present. And our nation to is now wielding the power as a suzerain state of Taekwondo. Consequently, in Korea, the suzerain state of Taewondo among the world, the study for the thesis of the theoretical background has been doing continually and steadily but the most fundamental fields of cultural society, especially the study in the side of philosophy among them has been very insufficient in fact. Taewondo is a martial arts to defeat the enemy by hardering the hand and the foot methodically, and Taewondo spirits, which is a spirits every person to learn Taewondo should have most fundamentally, is a mental ability to control the upright human acts, thinking or emotions through training andalsois the behavior ideas, expressed as mental power or will, to be the basis of moral deeds. In Taewondo, the mind is considered to be the driving force to plan the solution of problems caused by violent degradation and material-oriented tendency and the education of Taewondo is to stressed as the basis of desirable idea and behavior needed in the scene of games. Therefore, in order for the philosophical thesis of the spirits of Taewondo, we should generalize all these ideas to establish proper for the emotions of our nation, and in addition, should do both comprehensive and microscopic study and mental philosophy for Taewondo systematically and continually.

Aplastic anemia is one of the hematologic disease which is characterized by cytopenia in peripheral blood, hypocelluarity in bone marrow and marrow failure. Most common cause of aplastic anemia is unknown. Acquired causes of it are viral infection, drugs, and chemical agents. The symptoms of aplastic anemia are fatigue, headache, dizziness, exertional dyspnea, and pallor, and they are due to abrupt decrease in hemoglobin level. The incidence of acquired aplastic anemia is higher in Eastern population than Western. In geeral, men and women are affected with equal frequency, but the age distribution is biphasic, with the major peak in the teens and tweenties and a second rise in the elderly. We report a case of a 28-year-old man who experience aplastic anemia after ingestion of Cordyceps with the review of literatures.

Lutembacher's syndrome is rare combination of mitral stenosis (MS) and atrial septal defect (ASD). The hemodynamic interplay between the MS and ASD leads to wide variation of clinical presentation. Here we describe a 43-year-old female with Lutembacher's syndrome and tricuspid regurgitation with pulmonary hypertension, who underwent direct closure of ASD and tricuspid valvuloplasty successfully. We also reviewed other literatures in an effort to increase awareness of this condition.
