Wallenberg's syndrome is well known of dorsolateral medullary syndrome. A 56-year-old women was admitted because vertigo, vomitting, vertiginous ataxia, ipsilateral loss Rt. face and Lt. lower limb sense. The result of all performed laboratory tests were normal, but Sr-MRI scan was right lateral medullary infarction. And Br-MRA was focal stenosis of Lt. ICA. We present here one case of Wallenberg's syndrome, who was admitted at Kyungwon University Hospital From 25th Apr. to 21th May. 1998.

Congenital Cystic Adenomatoid Malformation [C.C.A.M], one of lung bud anomalies, is an unusual lesion, only about 200 cases baring been reported by 1980, and characterized by marked proliferation of terminal respiratory structures. Recently we experienced two infants with C.C.A,M., whose clinical courses were quite different. On case 1, the patient was 25-day-old female, and suffered from progressive respiratory distress for 10 days duration. A right middle lobectomy was performed, with a satisfactory postoperative course. On case II, the patient was 7omonth-old male, and admitted for evaluation of known pulmonary anomaly, which was detected for the first time during hospitalization for treatment of pneumonia at 1 month of his age. He underwent a lingular segmentectomy, but died of respiratory insufficiency on postop 10th day. We believe that awareness of the presence of C.C.A.M. is important in making the differential diagnosis of progressive respiratory disease or of recurrent pulmonary infection in infants.

In this paper, we surveyed the literature on QCC(quality control circle) and try to establish principles of activation of QCC activities in Korea. Although QCC activities in Korea, which originated from Japan, have so far made tremendous contributions to our domestic industry, many problems have also been found during the course of a, pp.ication to our industry. In this paper, we have paid much attention to the solution of the problems found during the initial stages and the a, pp.eciation of the achievements of QCC activities until now. We also suggest principles residing in the activities and propose the right direction of our QCC movement. We have made use of many known facts in our analysis and present some of them as evidences of our arguments.

Internationally, Korean people and society are known to be workaholic, however, recently some changes have come with the inauguration of the 5 working-days system as well as the rising of economic power and high level of education. Many people come to enjoy leisure time with various activities. Especially, arts become the subject of concern as a kind of leisure life, and also gallery become a important space. However, the renovation of the gallery space is required Inevitably because many galleries have been located in too formal or fixed building space, and the management of it has not been executed thoroughly. This study aims at the suggestion of the specialized and differentiated renovation plan for gallery as cultural space offering the right notion and information about the arts as well as rest to citizens, also as exhibit space showing the object efficiently.

Cytologic features of the fine needle aspiration of metastatic epithelioid sarcoma are presented. The patient was a 48 year-old male who had been sufferring from recurrent and metastatic tumors of the right upper extremity for 6 years. The aspirate from the axillary mass cytologically consisted of isolated large polygonal cells with abundant, cyanophilic, slightly granular cytoplasm. Eccentrically located large round nuclei showed finely dispersed chromatin, small nucleoli, occasional convolution and folding of nuclear membrane, and frequent binucleation. Although both histologic and cytologic similarity of epithelioid sarcoma to squamous cell carcinoma is well known, findings of cyanophilic granular cytoplasm, convoluted nuclei, and binucleation appeared to be the differential points.

This study is on Yoshimasu Todo's thought of medicines. Conclusions are as below. Medicines are poisons. Therefore, they don't have the ability to restore the vital energy. Medicine-processing(法製) can only be done for doubling the toxicity, since the poison itself is the very effect of a medicine. One poison has an ability to treat only one main symptom. If the poison strikes the main symptom right, it doesn't harm the human body. Since warm-heat-cool-cold(溫熱凉寒) of a medicine can't be known by human ability, it can't be used as the standard of judgment when selecting a medicine.

The purpose of this paper is an attempt to analyze the dynamic relationship between KSE and KOSDAQ, two competing markets in Korean stock market, in the viewpoint of competition. Lotka-Volterra model, one of well-known competitive diffusion model, is adopted to represent the competitive situations of Korean stock market and it is estimated using daily empirical index data of KSE and KOSDAQ during 1997~2001. The results show that there existed a predator-prey relationship between two markets in which KSE acted as a predator right after the emergence of KOSDAQ. This interaction was altered to a symbiotic relationship and finally to the pure competition relationship. We also perform an equilibrium analysis of the estimated Lotka-Volterra equations and, as a result, it is found that there is a market index equilibrium point that would be stable in the latest relationship.

Prior knowledge of arterial supply to the head and neck is of substantial importance for well-planned surgeries involving the concerned region. We are reporting an unusual and rare variation in the branching pattern of external carotid artery in a 60-year-old female cadaver. A common trunk known as thyrolinguofacial trunk, originating from the anterior surface of the external carotid artery (right and left) giving of superior thyroid artery and a linguofacial trunk during a routine neck dissection. The linguofacial trunk then divided into a lingual and a facial artery. Vascular abnormalities are usually detected either on the dissection table or by the radiologists during imaging or accidently during surgeries leading to serious consequences.

Orofacial pain can be caused by intracranial disorders or can be musculoskeletal, vascular, internal derangemental, and neurologic in origin. The neurologic pain is derived from structural and functional disorders of nerve, and the trigeminal neuralgia is the typical manifestation. Trigeminal neuralgia is known from centuries ago, and is one of the most common pains in human. We present our experience with three patients who have trigeminal neuralgia. The first case is a 50-year-old female who had no specific evidence radiographically. Second is a 50-year-old male with microvascular compression on right trigeminal nerve. The third case is a 60-year-old female who had a neoplasm in cerebellopontine angle with associated mass effect.

P. V$\acute{a}$mos called a ring R 2-good if every element is the sum of two units. The ring of all $n{\times}n$ matrices over an elementary divisor ring is 2-good. A (right) self-injective von Neumann regular ring is 2-good provided it has no 2-torsion. Some of the earlier results known to us about 2-good rings (although nobody so called at those times) were due to Ehrlich, Henriksen, Fisher, Snider, Rapharl and Badawi. We continue in this paper the study of 2-good rings by several authors. We give some examples of 2-good rings and their related properties. In particular, it is shown that if R is an exchange ring with Artinian primitive factors and 2 is a unit in R, then R is 2-good. We also investigate various kinds of extensions of 2-good rings, including the polynomial extension, Nagata extension and Dorroh extension.
