<P><B>Abstract</B></P> <P>In May 2015 a shallow-water acoustic variability experiment (SAVEX15) was conducted in the northeastern East China Sea. Surprisingly, an underwater sound channel that is typical for deep water was discovered in this shallow water waveguide (∼100 m deep) with the channel axis at around 40 m. For a broad-band source (0.5–2.0 kHz) deployed close to the channel axis, channel impulse responses observed by a vertical array exhibited a complex arrival structure with a large delay spread (e.g., 160 milliseconds). Most arrivals are found to be surface and bottom reflected, while a pair of high-intensity refracted arrivals are embedded in the early reflected arrivals. Broadband simulations based on a normal mode propagation model show good agreement with data.</P> <P><B>Highlights</B></P> <P> <UL> <LI> An underwater sound channel (USC) typical for deep water is found in the shallow northeastern East China Sea. </LI> <LI> Detailed observations on the environments and underwater acoustic data are presented. </LI> <LI> A complex structure of sound arrivals observed under the USC is separated into refracted and surface/bottom reflected ones with a broad-band simulation. </LI> </UL> </P>

미국수화언어와 한국수화언어에서의 WH-의문문

장세은 대한언어학회 1999 언어학 Vol.7 No.3

Jhang, Sea-Bun. 1999. WH-questions in American Sign Language and Korean Sign Language. Linguistics 7-3, 297-319. The purpose of this paper is to compare some aspects of wh-questions in American Sign Language and Korean Sign Language, and to show that the data from KSL share some arguments provided by the two current disputing analyses of the rightward and leftward wh-movement. In both ASL and KSL, a nonmanual wh-marking functions as a grammatical marker, and wh-words are in situ, or they optionally appear in sentence-final position. In addition, the two languages have the distribution of nonmanual syntactic wh-marking in common. When manual wh-material is available in sentence-final position, the spread of wh-marking over the rest of the sentence is optional; otherwise, spread is obligatory. Two pieces of evidence from KSL in favor of rightward analysis are (i) extraction of wh-words from within an embedded clause and (ii) left-dislocation of wh-words in sentences containing spatial verbs. In contrast, there are three pieces of evidence from KSL in favor of leftward wfi-mmovement: (i) variants of extraction of wh-words from within an embedded clause, (ii) sentence-initial wh-object, (iii) focus function of right-peripheral Wh-material in wh-doubles sentences.

Jhang, Sea-Bun & Yang, Sang-Baek. 1998. CP Specifier Analysis of It-Clefts in English. Linguistics, 6-2, 23-43. The purpose of this paper is to provide some evidence for a CP specifier of cleft constructions in English and to give a uniformed analysis of it-clefts. We demonstrate some problems of previous analyses: dual analyses by Pinkham & Hankamer (1975) and Chomsky (1977), successive cyclic wh-movement, preposing clefted constituents, negation scope, and binding theory B & C. We show that the CP specifier analysis can give an explanatory adequacy over the previous analyses, providing some evidence that cleft behaves like wh-question. We hope that this paper will be contributed to motivating the further study of the cleft structure in the Minimalist Program for current linguistic theory.

CASE REPORT : Familial Mediterranean Fever With Complete Symptomatic Remission During Pregnancy

( Kwang Taek Kim ),( Hyun Joo Jang ),( Jae Eun Lee ),( Mi Kang Kim ),( Jun Jae Yoo ),( Gye Yeon Lee ),( Sea Hyub Kae ),( Jin Lee ) 대한장연구학회 2015 Intestinal Research Vol.13 No.3

Familial Mediterranean fever (FMF) is an inherited autosomal recessive disorder, ethnically restricted and commonly found among populations surrounding the Mediterranean Sea. FMF is the most prevalent autoinflammatory disease; is characterized by recurrent, self-limited episodes of fever with serositis; and is caused by Mediterranean fever gene (MEFV) mutations on chromosome 16. We describe a case of adult-onset FMF with complete symptomatic remission during pregnancy, without the use of colchicine. A 25-year-old woman had presented with periodic fever, abdominal pain, and vomiting since she was 21. Her abdominal computed tomography scan showed intestinal nonrotation. She underwent exploratory laparotomy and appendectomy for her symptoms 1 year prior. She had a symptom-free pregnancy period, but abdominal pain and fever recurred after delivery. Mutation analysis of the MEFV gene revealed two point mutations (p.Leu110Pro and p.Glu148Gln). We report an adult female patient with FMF in Korea with complete symptomatic remission during pregnancy. (Intest Res 2015;13:287-290)

To examine the taxonomic relationships among 6 cultivars by 14 flower morphological characters, principal component analysis and cluster analysis were carried out. In this study, we analyzed the flower morphological characteristics of three new hadry kiwi (Actinidia arguta) cultivars and three new hybrid kiwi (A. arguta×A. deliciosa) cultivars to investigate the species classification and the potential for using honey plants. As result of principal component (PC) analysis using 14 variables from 6 cultivars, eigen value of the first principal component was 8.9054 and the first two PCs was accountable for 74.00% of the total variance. The first PC was correlated with those characteristics that were mainly related to the color of width of inflorescence, color of petal a, length of pedicel and no. of stamen. From the cluster analysis using UPGMA method, we can assumed that six cultivars could be clustered into two groups. Group Ⅰ comprises three A. aruguta, Sea-Han, and Dea-Sung, Chil-Bo, and the other one, Group Ⅱ consists of three hybrid kiwi, Dea-Myng, Hwang-Oak, and Ja-Wang.

貿易賣買契約에 關한 硏究 : With a special emphasis on the liabilities and responsibilities between the sdller and the buyer of a CIF contract C.I.F. 契約을 中心으로

吳世昌 啓明大學校 産業經營硏究所 1978 經營經濟 Vol.9 No.1

The purpose of this study is to examine and analyze the relationship between the seller and the buyer from the view from the view point of responsibilities. The reasearch method used in this study was a bibliographical search of the material available in the library of Keimyung University and the library of Busan National University. An analytical approach was also used to the cases occouring in the practice of international trade. The boby of this study is devided into five sections. The first section deals with the international rules for foreign sales contract which is effected on foreign trade. The second section deals with the nature of a C.I.F. contract. The third section includes discussions of problems which could be raised by the concerned parties in documents and goods. The forth section covers the following boundaries of responsibilities of the seller and the buyer of a C.I.F. contract. 1. C.I.F. contract as a sale of goods. 2. the seller as shipper and exporter 3. the effective bills of lading and marine insurance policy 4. the tender of valid and effective document. 5. the time of the passing of the property and the risk 6. the time of payment 7. province of C.I.F. contracts In conclusion followings are; 1. The statement that a C.I.F. sale of documents is a useful phrase to remember, particulary when questions as to damages for breach of contract arise. But the contract is more correctly described as "a contract for the sale of goods to be performed by the delivery of documents." 2. The duty of seller under a C.I.F. contract has to ship at the place of shipment, within the time named in the contract or within a reasonable time, goods of the contract description, and notify the buyer, without delay, that the goods have been loaded on board the vessel, to comply with the formalities, to obtain any export licence or other governmental authorization necessary for the export of the goods at his own risk and expense, to contract on usual terms at his own expense for carriage of the goods, and also upon the terms current in the trade, ordinary contract of insurance of the goods on that voyage. 3. Unless otherwise expressly stated in a C.I.F. contract, the seller under a C.I.F. contract must supply a clean negotiable bill of lading issued on shipment and in a transferable form, and a policy of marine insurance wnich shall be provided in the currency of the contract, if procurable. 4. The documents must be valid and effectire at the time of the tender. The tender of documents which were originally valid but before tender have become invalid is not a good tender. Therefore, the seller must, as soon as possible after he has sent forward the cargo, send forward the documents to the vendee or consignee. 5. As a general rule in a contract for the sale of goods, the property and the risk pass at the same time, but this is not the usual case in a C.I.F. contract. Under a C.I.F. contract the risk generally passes on shipment, but the property in the goods may not, and generally does not, pass on shipment. It very often will not pass until tender and payment. 6. The seller having tendered the proper documents, it becomes the buyer's duty to accept and pay in accordance with the terms of the contract. 7. As a general rule, therefore, the designation of a contract as a C.I.F. contract creates a strong inference in favour of its so being construed, and, unless that inference is overcome by express provisions showing that the parties intended otherwise, its meaning is not vitiated.

초기배자로부터 분할란의 성(性) 감별과 분할배의 발생 성공은 성의 식별과 더불어 유전적으로 우수한 개체의 생산이 가능함을 의미한다. 따라서 본 연구에서는 새앙쥐(mouse) 및 소의 초기배자 상태의 수정란을 이용한 염색체 분석 기술을 개발하고, 각 수정란의 성의 판별과 이들의 유전적 특성을 구명하고자 하였다. 초기 배자를 이용한 염색체 분리의 최적 조건을 결정하기 위하여 colcemid의 농도, colcemid의 처리시간 및 공시된 배자의 발생단계별 분석을 새앙쥐의 배자로서 수행하였다. 분석 결과 염색체 분리에 있어 colcemid의 처리 시간이 유의적인 차이를 보인 반면 다른 요인들 간에는 별다른 차이가 없는 것으로 나타났다. 소의 체외수정란을 이용한 염색체 분석에서는 공시된 수정란의 93%이상에서 증기상의 유도가 가능하였고, 이들 중 65%에서 성의 식별이 가능하였다. 또한 수정란의 분석된 성비는 1:1로서 자연적 성비와 일치하였다. 염색체 분석에 의한 배자의 조기성 감별은 처리 과정상의 기술적 요인들에 의해 매우 큰 영향을 받는데 특히 hypotonic의 처리방법 및 fixation의 방법을 적절히 처리하므로서 효율적이고 높은 성공률을 기대할 수 있다. Chromosome analysis from biopsied or splitted embryos which were fertilized in uitro or in vivo implicates a possibility of production of the genetical superior animals and sex controlled individuals. Therefore, this study was carried out to develop the technical method for chromosome preparation from early bovine and mouse embryos and to identify their sex and genetic characteristics. To determine optimum condition of chromosome preparation, the several factors which include the concentration of colcemid, the duration of culture and embryonic stage were analyzed from mouse embryos. According to analysis, the duration of culture had significantly influence on chromosome preparation. The other factors were not significantly difference among the treatments. In the results of chromosome preparation from intact bovine embryos, the rate of embryos with one or more metaphase plates was 93%, and of embryos with sex analyzable metaphase chromosomes are 65%. Sex ratio of male and female was approximatly 1:1 same as natural sex ratio. The inducing rate of analyzable metaphase was mainly due to technical aspects, expecially hypotonic treatment and fixation.

생명과학기술 시대, 양명학과 생명윤리

김세정 가톨릭대학교 인간학연구소 2004 인간연구 Vol.- No.6

본 논문에서는 생명과학기술의 발전에 따른 생명윤리 문제와 관련한 유교에 대한 평가와 그 문제점들을 진단하고, 나아가 왕양명의 생명관을 고찰함과 아울러 양명학의 생명관을 바탕으로 한 생명윤리의 정립 가능성을 모색해 보았다. 생명과학기술 시대, 임신중절과 장기이식 및 인간복제문제와 관련하여 유교는 남아선호사상과 가족이기주의로 인해 반생명적·반윤리적이라고 평가된다. 그러나 우리는 왕양명의 만물일체의 생명관에 대한 새로운 이해를 통해 생명과학기술 시대에 있어 유교 생명윤리를 새롭게 모색해 볼 수 있다. 예컨대 양명의 天地萬物 一謄說에서는 태아의 생명을 포함한 모든 인간생명의 존엄성뿐만 아니라 인간생명을 건강하게 보살피고 양육해야 하는 인간의 실존적·실천적 당위성의 근거를 찾아 낼 수 있다. 비록 태아가 여아라 하더라도 내가 보살피고 양육해야 할 천지만물의 한 부분으로서 살고자 하는 의지(生意)를 내재하고 있기 때문에 태아를 살해하는 임신중절은 결코 허용되지 않는다. 그리고 타인과 나는 한몸이기에 타자의 아픔은 곧 나의 아픔으로서 장기이식을 필요로 하는 타자의 아픔을 외면할 수 없으며, 더욱이 인간의 생명 본질인 인심(仁心)은 가족의 울타리를 넘어 전 인류 나아가 자연만물에게까지 확대되기 때문에 타인에 대한 장기이식을 부정하고 가족에만 국한할 수는 없다 마지막으로 인류가 하나의 상위 생명체이고 인간유전자는 인류 공통의 유산이라고 할 때, 자신의 생물학적 자식에만 너무 집착한 나머지 입양과 같은 방법들을 외면하고 현재 직면하고 있는 생물학적 위험과 윤리적 문제들을 무릅쓰면서까지 인간복제에 의존하거나 집착해서는 안 된다. This article studies confucianism in relation with bio-ethical issues that have arisen from the development of bio-science technology. It reveals the problems of confucianism and approaches the confucian view of life from the perspective of Yang-ming Studies. It seeks for the possibility of establishing confucian bioethics on the basis of Yang-ming Studies's view of life. In the age of bio-science technology, confucianism is viewed as against life and ethics for the following reasons. The male-oriented concept of confucianism causes the abortion of a female fetus. The sense of filial duty in confucianism also causes the reluctant attitudes toward transplantation of internal organs, and a rare case of transplantation is limited only within the circle of a family. Human cloning is acceptable according to the confucian view of continuous life and its family-centered view. However, we can have confucian bioethics appropriate for the age of bio-science technology with a new understanding of the confucian view of life. For example, in the concept of Yang-ming that all creatures are one and the same, we find the ontological and practical obligation for life, such as taking care of and bringing up human life, as well as its own sanctity itself. A female fetus is a part of nature that clearly expresses the will for life; therefore, abortion cannot be acceptable in all respects. Since the other and I are one and the same, the other's sufferings are mine. So we cannot avoid the other's need for transplantation. Furthermore, the humaneness of humans is extended to the whole humankind and any form of life, and we should not limit transplantation within the circle of the family. If humans are a superior form of life, and the human gene is the inheritance of the whole mankind, we cannot stick to our biological offsprings and avoid an alternative way such as adoption. We should not rely heavily on human cloning in spite of the biological dangers and ethical problems that we are facing at present.
