<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>

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.

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.

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)

The corrosion fatigue test was performed under rotated bending in salt solution having a concentration from 0.01 wt percent to 3.5 wt percent to investigate the corrosion fatigue crack propagation characteristics for dual phase steel. Corrosion pits were occurred in martensite, and microcracks occurred at corrosion pits were selectively propagated towared martensite because slip bands were not found in ferrite which were encapsulated by martensite. The number of corrosion pits, the diameter of corrosion pits and the length of corrosion cracks for M.E.F. and raw material(R.M)were increased with the concentration of salt solution and the number of cycles. The initiation of crack was almost same regardless of the concentration of salt solution; approximately N??/N??=20% in case of M.E.F. and N??/N??=14% in case of raw material (R.M.) The difference of corrosion fatigue crack propagation was increased with an increase in concentration of salt solution. The corrosion resistance effect of dual phase steel was smaller than that of raw material (R.M.) in corrosion fatigue crack propagation rate.

Secondary school teachers' leasure activities which exert great effects on middle- and high-school students' thought and behavior become an important factor for their profession and sentiment. This study examined secondary school teachers' leasure activities in relation to gender, years of teaching experience, and marriage via survey methodology. The results of the study can be summarized as follows: 1. Female teachers tended to have less time in weekdays than did male teachers. 2. Married teachers tended to prefer outdoor activities on weekend. 3. Both female and male teachers were found to spend last summer vacation doing general leisure activities such as reading, meditating, collecting, and exploring. 4. More female teachers than male teachers tended to consider that principals, vice principals, and head teachers did not have much interest in leisure. 5. Among the obstacles to teachers' leasure activities were lack of time, place, and facilities.

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.
