Tuberous sclerosis is a rare disease, which occurrs sporadically or hereditarily and is recognized by its neurological and dermatological manifestations. The classical triad is composed of seizure, mental retardation and adenoma sebaseum on face. A 33-year-old woman was hospitalized with end stage renal disease due to renal angiomyolipoma and maintenance hemodialysis was initiated. Biopsy of facial skin revealed adenoma sebaseum. Abdominal CT showed angiomyolipoma in both kidneys and multiple cystic lesions in both adnexae and retroperitoneal space. And the patient suffered from bilateral pneumothorax which resulted from the invasion of tuberous sclerosis to the lung the lung expanded completely. Emergency closed thoracotomy tube drainage was performed. She has been managing with maintenance hemodialysis until now.

본 논문에서는 six-port 위상 상관기와 신호 검파부 그리고 I 및 Q 채널 신호를 복조하는 간단한 구조를 갖는 six-port 직접 변환 QPSK 수신기를 설계하고 제작하였다. Six-port 위상 상관기의 출력 단자간 출력 위상 신호를 해석하고, 출력 단자 신호 간 $90^{\circ}C$ 위상 관계로부터 QPSK신호를 복조하는 간단한 회로의 직접 변환 수신기 구조를 갖는다. Six-port 위상 상관기는 $90^{\circ}C$ 하이브리드 branch line 및 전력 분배기를 가지며, $11.7{\sim}12.0\;GHz$ 주파수 대역에서 설계된 six-port 위상 상관기의 출력 신호는 $^{\circ}$ 이내의 양호한 위상 오차 특성을 갖는다. 또한 직접 변환 수신기 구성 소자간 양호한 정합도 및 진폭 특성에 의해 약 $5^{\circ}$ 이내의 위상 오차를 갖는 I, Q 데이터를 복원하였다. A simple six-port direct conversion QPSK receiver which is made up of a six-port phase correlator, a signal power detector, and I/Q channel signal de-modulator is designed and implemented in this paper. The output phase signals of six-port phase correlator are also analysed. On the basis of $90^{\circ}C$ phase relation among the six-port phase correlator output signals, the QPSK de-modulation circuit is designed by a simple circuit. The six-port phase correlator is made up of $90^{\circ}$ hybrid branch line and power detector. The six-port phase correlator, which is designed in frequency range of 11.7 to 12.0 GHz, gets the phase error characteristics less than $5^{\circ}$. By considering matching network and amplitude balance in the designed fiequency range, the designed six-port direct conversion QPSK receiver demodulates the I and Q signals with performance less than $5^{\circ}$ phase error.

濟州 觀光資源의 國際市場性

International tourism is the largest single item in the world's foreign trade and for some countries it is already the almost important export industry and earner of foreign exchange,' So, in this article, I sum up the economic and social importance which attaches to the present day tourist phenomenon. Looking at the benefits which arise from tourism, I am even more positive : "The economic gap between rich and poor countries has widened over the past ten years. But to create new industries and to transform rural life in asian, african and Latin american countries is a gigantic task. The relevance of tourism to this situation is that income from international travel can bring the foreign exchange essential for major investment. There is widespread awareness of the potential benefits, but little has been done in practice to provide the means for expansion of tourism plant in most of the developing areas of the world." This Island wishing to establish an international tourist industry must be able to answer number of questions : what is the tourist industry worth at present? Can its expansion be expected to continue ? are there any signs of a setback in the growth of the industry? Should steps hs taken to protect and develop its tourism appeal and to attract new tourists to the country? Is it possible to retain a balance between confilcting industrial and urbanisation needs and the protection of potential tourist attractions? It is the aim of this article to show these questions could be answeredie order to maxlmise the benefits of international tourism on economic and social developments. By the year 2,000, in most countries, a large and increasing population generates such an enormous demand for non-recreational as well as for recreational uses of land and water that recreation may never get its full share. This can be considered partly as a matter of inherent may never get its full share. This can be considered partly as a matter of inherent limitations of space and partly as a problem of establishing priorities. Overcrowing at beaches and local parks may seem inevitable. But this should put a premium on the efficient use of the land that is available for recreation as well as for industry and housing, and in most countries there has been a conspicuous failure to plan for the most efficient use of scarce land resources. So, Jeju Island in the year 2,000 will be able to become the best place in the world for person's travelling for leisure, health.

언어학에 있어서 플라톤 문제

양우진 제주대학교 1990 논문집 Vol.31 No.1

Languages are the best mirror of the human mind. Knowing the language is a property of a person; on task of the brain science is to determine what it is about a person's brain by virtue of which this property holds. Chomsky suggested that for a person to know the language is for the person's mind/brain to be in a certain state. The language faculty is a distinct system of common to the species. This faculty passes from the state S_o to some relatively stable steady stats S_s, UG is the theory of S_o and CG is the therory of S_s: particular grammars are theories of various I-language. All the devices of language are meager enough so that very few languages are made available to the language-learner, given data that, in fact, suffice for language acquisition. These conditions of the variant of Plato's problem set the important task that the rearch program must address. Two perspectives can be distinguished in the study of grammar, one which emphasized rule system and the other, systms of principles. There has been a gradual shift of focus from the study of rule systems, which has increasingly been regarded as impoverishe, to the study of systems of principles, which appear to occupy a much more central position in determing the character and variety of human language. In long run, I believe Chomsky's greatest contribution will be that he has taken a major step toward restoring the traditional conception of the dignity and uniqueness of man.

Grammar has three fundamental components, organized as in the following : ◁그림 삽입▷ (원문을 참조하세요) In this article, I discuss the properties of Move-α:wh-movement and Np-movement. wh-movement moves a constituent to an A'-position. leaving a co-indexed trace. I have discussed the properties of the target of movement, of the landing site and of the trace. Typically wh-movement is involved in the formation of questions. where a wh-phrase is moved to 〔Spec, CP〕, movement cannot cross more than bounding node. The bounding nodes are subject to parametric variation. In English IP and NP are bounding nodes:in CP and NP are bounding nodes. NP-movement is illustrated in passive and raising structures. It affects NPs which cannot be case-marked in their base-position. NP-movement leaves a co-indexed trace which is a non-pronominal anaphor, hence subject to Principle A of the binding theory. The moved antecedent NP and the trace form a chain. Verbs which induce NP-movement are those which lack an external theta role and fail to assign ACCUSATIVE case. These verbs are referred to as unaccusative verbs. The structure preserving principle imposes severe restrictions on the effect of Move-α. The theta criterion and the extended projection principle are argued to apply at both D-structure and at S-structure, while case theory and the binding apply at S-structure.

요추간판의 전산화단층촬영술 II. 요추간판탈출등 소견

In Iumbar region the epidural fat pad is relatively abundant so that CT can provide sufficient informations in diagnosis of lumbar HNP. Many authors have reported on the CT findings of HNP such as focal nodular protrusion of the posterior disc margin, obliteration of epidural fat pad, impingement of dural sac and nerve root, swelling of nerve root, soft tissue density in the spinal canal and calcification of disc. However three was no previous report describing indidence and reliability of these findings. It is the purpose of the present study to survey the frequency, reliability, and limitation of these CT findings. The clinical material was consisted of 30 operatively proven cases of HNP of the lumbar spine. Each lumbar CT scan was reviewed retrospectively and the findings were analysed by two radiologists independently. there were 20 males and 10 females and the mean age was 36.7 years. Involvement of L4-5 level was 2.3 times more frequent than that of L5-Sl level. Of 30 cases, 22 were unilateral posterolateral types and 8 cases central or unilateral far lateral types. CT findings observed were nodular protrusion of the posterior margin of the disc, obliteration of epidural fat pad, impingement of dural sac or nerve root, soft tissue density in the spinal canal and cal- cification in the posterior portion of the protruded disc, in order of decreasing frequency. The conclusions are as follows : 1. Nodular protrusion of the posterior disc margin accompanied by obliteration of epidural fat pad was observed in every case. The former finding was designated as direct sign and the latter indirect. 2. Obliteration of the epidural fat appears to be significant in lateral recesses especially when it occurs unilaterally. This was not true, however, in the centraly located fat pad. 3. Impingement of the dural sac and nerve root were observed in 90% and 67%, respectively, and were very helpful in establishing HNP diagnosis when the direct and indirect signs were equivocal. Metrizamide CT scan facilitated the evaluation of the dural sac and nerve root. 4. Soft tissue density in the spinal canal and calcification in the posterior portion of the protruded disc were demonstrated in only 2% and 1% of the cases, respectively.
