Kang, Seok-Han. 2006. Effects of Language, Age and English Listening Level on Voicing Perception of English Final Stops. Korean Journal of Linguistics, 31-2, 187-205. To understand the preceptual change pattern during L2 learning, this study examined the identification correctness of word-final stops and cue robustness for the unit intervals in light of background language, age, and English listening level. The 4 groups of Native Speakers of English, Korean College Students of High Listening Achievement, Korean College Students of Low Listening Achievement, and Korean Elementary Students took part in the experiments. Tokens of /dæp, dæb, dæt, dæd, dæk, dæg/ were extracted and modified into experimental signals composed of two digits (voiced-1, voiceless-0) by following the temporal intervals. In the first experiment of identification correctness of final stops, Native Speakers of English showed almost 100% correctness rate in both environments, while those of Korean showed 70% to 95% correctness rate depending on environments. In this test, neither age nor the listening level influenced significantly the voicing correctness to Korean subjects. In the second experiment of the cue robustness, the group of Korean Elementary students, unlike Korean College students, showed the similar perceptual pattern with that of native English speakers in the released environment. This result strongly suggested that the phonological system of the native language as well as the psycho-linguistic pattern of the universal language deeply influenced L2 perceptual system.

정지궤도 위성과 지구국간 광통신을 대기상태와 앙각의 함수로써 해석할 수 있는 한모델(Han's model)을 제시하였다. 한모델에서는 대기상태를 맑은날, 구름낀 날, 안개, 헤이즈, 비, 눈의 여섯가지 전형적인 상태로 구분한다. 비트오류을 $10^{-7}$을 만족하는 데이터 전송속도를 한모델을 이용하여 상향링크와 하향링크에 대해 해석하였다. 상향링크시의 포인팅손실이 하향링크시의 대기에 의한 공간 가간섭 저하보다 크기 때문에 데이터 전송속도는 하향링크 보다 오히려 상향링크시에 제한됨을 알 수 있었다. Han's model, which is able to analyze optical communication between earth station and geo-satellite as a function of atmospheric conditions and elevation angles. is presented. In Han's model, atmospheric conditions are roughly classified into six basic types; clear sky, cloud, haze, fog, rain and snow. Data rate satisfying for the BER below $10^{-7}$ is analyzed by Han's model in case of up-link and down-link, respectively. Data rate is more limited by up-link than by down-link because the pointing loss caused by atmosphere on the up-link is greater than the spatial coherence degradation caused by atmosphere on the down-link.

A Comparative Study on Accentual Patterns between Middle Korean and the Current Jeju Korean

Seok-Han Kang 한국언어학회 2015 언어 Vol.40 No.1

Kang, Seok-Han. 2015. A Comparative Study on Accentual Patterns between Middle Korean and the current Jeju Korean. Korean Journal of Linguistics, 40-1, 1-18. The study reports that bi- and tri- syllabic nouns in the Jeju dialect of Korean keeps phonetic features of Middle Korean tone types, whereas no relation was found in the mono-syllabic nouns. The experimental result on 104 nouns which classified by following Middle Korean tone types implies the importance of syllable structure in the tonal change. In this study, the accentual patterns of Jeju Korean follows those of Kyungnam dialect of Korean;low tones change into high accentual patterns, high tones into low patterns, and falling tones into high patterns. But the change occurs in the phonetic level, not in the phonology, in which the H accent could be realized as higher F0 and longer duration. This means that the phonological tone patterns change into the phonetic accent in multi-syllable words. In this study, we can find some possible relationship between Jeju Korean and Middle Korean. It implies that Middle Korean was not a real tonal language. (Konkuk University)

The purpose of this study is to suggest optimum size of residents' bedrooms in nursing homes. Bedroom is an essential part of nursing homes because nursing home residents spend most of their times in bedrooms and occupy the largest part of facility area. Therefore it is necessary to set an adequate standard related to resident room area in nursing facilities, which have a great effect on planning longterm care facilities for the elderly. The body dimensions of elderly people and care givers have been collected from the previous study. Based on the body dimensions data, the behaviors of elderly as well as care givers have been analysed. The minimum areas-exclusive of toilets, closets, vestibules and so on - have been proposed from the results of the behavior analysis.

한강 하류의 남조류 및 환경요인의 연간 (2000 ${\sim}$ 2003) 변화에 대하여

서미연,김백호,배경석,한명수,Suh, Mi-Yeon,Kim, Baik-Ho,Bae, Kyung-Seok,Han, Myung-Soo 한국하천호수학회 2005 생태와 환경 Vol.38 No.2

한강 중하류의 남조류 및 환경요인의 연간변화 (2000 ${\sim}$ 2003)를 파악하기 위하여, 2000년 4월부터 2003년 10월까지 4년간 성수대교에서 성산대교까지 총 5개 지점을 선정하여, 수계의 기초환경요인 및 식물플랑크톤 현존량 변화를 조사하였다. 조사기간 동안, 남조류의 현존량은 점차적으로 감소하여 장기간 강우가 가장 많았던 2003년에는 거의 관찰되지 않았으며, 총 식물플랑크톤 현존량에 대한 남조류의 기여도는 약 10%범위내였다. 이러한 현상은 매년 강우집중기 동안 팔당댐으로부터 많은 방류수가 유입됨으로서 수온감소는 물론 광량감소, 영양염류 희석 등에 의한 남조류의 성장이 제한된 것으로판단되며, 동일시기에 다른 조류 (녹조, 규조 등)의 높은 성장으로 엽록소 a와 식물플랑크톤 현존량이 뚜렷하게 증가하였다. 따라서 한강 하류의 고온기 동안 남조류 성장은 잦은 강우와 방류에 의해 제한을 받지만 규조나 녹조와 같은 다른 조류들의 높은 성장으로 대치되는 천이현상을 보였으며, 기후영향을 크게 받는 전형적인 하천생태계의 특성을 나타냈다. For 4 years (2000 ${\sim}$ 2003), annual fluctuations of standing crops of cyanobacteria and physicochemical factors were examined at five sites from Bridge of Seungsoo to Bridge of Seungsan in the lower part of Han River. The cyanobacterial abundance (ND to 4,167 cells $mL^{-1}$) was strongly decreased during the heavy rains in every year. During the similar periods in 2003, cyanobacteria hardly observed, and comprised below of 10 percentage of total phytoplankton. In the period of little cyanobacteria, some green algae and diatom dominated the phytoplankton community, while the concentration of chlorophyll a has not largely change. These results indicate that heavy frequent precipitation strongly limited the growth of cyanobacteria, and lead an algal succession by the appearance of new algal groups.

최근 국가기간 철도망의 도심지 통과시 민원 및 환경, 기존 노선과의 접속 등의 이유로 구조물 근접, 하저, 퇴적층~경암의 복합지반 등 점점 더 가혹한 현장조건에서도 터널공법의 적용이 요구되어 지고 있으며, 이들 조건에서도 안전하게 시공이 가능한 쉴드(Shield) TBM에 대한 적용이 증가하고 있다. 본 고에서는 대곡~소사 복선전철 민간투자시설사업 구간 중 한강 하저를 횡단하는 철도 쉴드(Shield) TBM 터널 설계시 주요 고려사항에 대해 기술하고자 한다. 특히, 하저구간 통과시의 고수압 조건과 한강 하류지역의 지질학적 특성으로 인한 풍화대 심도가 불규칙한 복합지반, 다수의 단층파쇄대, 퇴적층 등의 불량한 지반조건을 통과하기 위한 쉴드 TBM의 검토사항과 터널안정성 확보를 위한 주요 설계 방안을 중점적으로 다루고자 한다. Recently, despite of the harsh conditions such as adjacent structures, underwater tunnel, and complex grounds, tunnel construction has been performed inevitably in underground metropolitan area because of civil complaint, environment and connection with existing railway. Thus, it has been increasingly demanded to be constructed by Shield TBM excavation method that can be a safe way under these adverse conditions. In this paper, we would like to introduce the major considerations about the shield tunnel design for passing through under the Han-River among the BTL Project of double-track electrification in the Deagok~Sosa section. Especially, Focus on key design strategies are discussed in Shield TBM and securing the tunnel stability for passing through under the river, such as high water pressure, complexity ground, many fault fractured zone, sedimentary layer

崔松雲堂의 文學世界와 現實認識 : 「諺文詞藻」를 중심으로

韓碩洙 한중인문학회 2004 한중인문학연구 Vol.13 No.-

최송설당은 한말 국권 상실기에 교육사업과 문필에 큰 족적을 남긴 선각적인 여성이다. 그가 남긴 문학 작품은 한시가 167수이고 '언문사조(諺文詞藻)'라고 한 가사 작품이 49편이다. 이 글은 그의 가사작품 49편에 대하여 논의한 논문이다. 전반적인 그의 문학 작품은 대부분 1914년 이전에 지어진 것으로 가사문학사에서 보면 쇠퇴기의 작품이요, 내방가사에 속한다. 49편의 가사를 내용별로 보면 조상을 위하는 것, 고향을 생각한 것 , 경물을 노래한 것, 늙음을 한탄한 것, 신세한탄 등으로 나눌 수가 있다. 그의 가사작품은 표현기법의 면에서 섬세하고 감성적이며 언어구사가 적절하다. 작품의 세계는 세계에 대한 관조와 정관, 홍경래난에 연좌되었던 조상을 위하는 마음, 인생을 돌아보고 한탄하는 마음 등을 특유한 여성적 감각으로 담담하게 표현하였다. 최송설당의 가사 작품에서 두드러진 사상은 지절과 신의였고 충의가 강조되었다. 그것은 국권을 상실한 조국을 향한 것이기도 하였다. Choi Songseoldang was born of a ruined yangban(Korean aristocratic class) and learned Chinese classics from her father. In old age, she became rich and stable in social status. She wrote 49 kasas and 167 Chinese poems. Her kasas are various in subject matter and contents. Her expression is very delicate, full of allusions form the classics and her language is appropriate. Her works show woman's sentiment, intuition and contemplation. In some works, she tells also the family consciousness, respect for ancestors, lament for old age and frailty of human life. From her kasas, her view of life and world can be analogized, in many works she emphasizes fidelity, loyalty and filial piety. Her fidelity is for Erm-bee(consort) personally; broadly for the mother land. Choi was a talented writer. Through the technique of expressing her personal emotion plainly, she shows her view of life and world. When she lived, her country lost the sovereign rights and she included also her nationalism and love for the motherland in her works.

韓美關係의 變化와 特續性에 관한 硏究 : 한국의 국가이익을 중심으로 Focus on Korea's National Interest

한석지 제주대학교 사범대학 2001 백록논총 Vol.3 No.1

The relationship between Korea and the United States, in the Post-Cold War era, can be either changed, or conflicted, and continued, while reflecting the different aspects from those secret treaties that were made between various other nations under the Cold War era right after the Post World War Ⅱ. As the situation commonly referred to as the "Post-Cold War Era" is considerably watering down the fundamental reason why the United States have maintained her alliance relationship with Korea, showing the possibility of substantial changes in their relationship for the future. The relationship between two countries reflect more mature look not only because of the international environment called "Post-Cold War" but also because of the United States changes her thinking towards Korea due to Korea's economic growth and her progress towards democratization. Let alone such mature look reflecting their relationship between two countries, new various complicated matters are occurring relating the national interests of these two countries. The fundamental conflicts that occurs even under friendly alliance relationship between two countries, are underlying different perspectives between those interests each country might have in, also hold unforeseen conflicts between them. These two countries are challenged to be tested for their diplomatic capacity to address vital current matters between Korea and the United States including the foreign affairs and trades, each share of defence expense, restructuring the national security and cooperation that have been constantly issued. The international society is now taking a further step into the cold and severe utilitarian diplomacy era rather than empty ideological argument. The Korean Government, therefore, shall develop more independent and realistic diplomatic policy in the preparation for the real reunification era. Of course, the scientific analysis on the international trends prior to Cold War Era and their diplomatic policy shall be done first.
