This paper deals with consideration for transient stability of power system The analysis of transient stability is very important because it detects the possibility of large scale outage by system collapse caused system configuration change and load unbalance. Two units YGN 3&4 will be connected to the YGN 1 & 2 switchyard through two 345KV circuits until 1996 because of the nuclear power plant construction according to power demand increment. Therefore it is necessary to study stability analysis, fault capacity calculation and power flow problem in assumption of two units YGN 3&4 operation interconnected with the power system Finally, considerations of the effect of interconnection and the establishment of preservation methods for reliability of stable opration of the power system are included in this paper.

자연스러운 합성음을 위한 한국어 여성음의 지속시간 변화 법칙

권철홍 大田大學校 産業技術硏究所 1997 산업기술연구소 論文集 Vol.8 No.2

Accurate prosodic control of pitch, segmental duration and intensity is very important for the naturalness of synthesized speech. In this paper we make a rule of duration variation for a natural synthetic female voice. Factors relevant to duration variation are the position and the number of syllables in a word, the effects of neighboring phonemes and speaking rate. The rule of duration variation extracted from enormous sentences uttered by three female speakers is presented and some simulation results are shown. According to our informal listening tests, the naturalness of synthesized speech is greatly improved.

PS-RELP 방식을 이용한 TTS 합성음 품질의 성능 향상

권철홍 대전대학교 산업기술연구소 1998 산업기술연구소 論文集 Vol.9 No.2

본 논문은 TTS 음성합성의 평가 척도인 사람 목소리와 이해도라는 척도 중에서 사람 목소리에 관한 주제를 다루고자 한다. 이를 위하여 음성 DB의 합성 단위로 주위 음소 환경을 고려한 CVC type을 기본으로 하고, CV,VC type으로 보강한 단위를 선정하여 음성 DB를 구축하였다. CVC type DB의 수는 산술적으로 10,962개이나 사용 빈도수를 조사하여 그 중에서 사용 빈도수가 많은 2,923개만 CVC DB로 구축하였다. CV,VC type에 해당하는 DB는 1469개이므로 전체 DB 총수는 4392개이다. 그리고 합성 알고리즘은 TD-PSOLA 방식의 단점인 피치 조절의 한계를 극복할 수 있는 음성 파형 생성 알고리즘에 대하여 연구하여 PS-RELP 방식을 제안하였다. 이 방식은 스펙트럼 성분이 제거된 residual 신호를 overlap-add 하므로 음성 신호의 스펙트럼을 그대로 보존할 수 있다는 이점이 생겨서 TD-PSOLA 방식 보다 피치 조절의 자유도가 확대된다. For a Korean TTS system, we construct speech database which is composed of CVC type and CV,VC types. CVC type database is constructed by considering surrounding phoneme environments, and its number is 2,923. The number of CV,VC type database is 1,469, and therefore total number of the database is 4,392. For a TTS synthesis algorithm, we propose a PS-RELP(Pitch Synchronous Residual Excited Linear Prediction) method. It remedies the shortcomings of TD-PSOLA method that places a restriction on pitch control. It overlap-adds residual signals which contain no spectral components, and therefore it conserves the spectral components of a speech signal

干拓地에서 潮位와 地下水位와의 關係에 對하여

權武男,李根厚,金哲會 慶尙大學校 1975 論文集 Vol.14 No.-

The relation between tide level and ground water level in reclaimed land is one of important imformations to make the successful agriculture in reclaimed land and water resources development. To clarify this relationship, an investigation was made at the newly reclaimed land located in Gyeong-nam province. Obtained results were as follows: 1. The fluctuation of tide level affected significantly (r=0.468*∼0.670**) the ground water level variation in reclaimed land. 2. The nearer to shore line, the greater the effect of tidal fluctuation on ground water level. It was found that no significant effect of tidal fluctuation on ground water level existed beyond the range of 2km from shore line. 3. The average ground water level during the rising interval of tidal curve was higher than the average ground water level during the falling interval of tidal curve. 4. The magnitude of ground water level variation curve was one half of the magnitude of tidal curve.

예비교사의 교육실습에 대한 셀프내러티브 탐구

권선미,조철기 부산대학교 과학교육연구소 2013 교사교육연구 Vol.52 No.1

본 연구는 내러티브 탐구를 적용하여 예비교사가 교육실습기간 동안 겪게 되는 경험은 어떤 것이며, 이러한 경험은 어떤 의미를 가지는가를 알아보았다. 내러티브는 경험을 잘 나타낼 수 있는 도구로써 이를 수집ㆍ분석하기 위해 교육실습생인 연구자의 실습일지와 학생들의 학습일지를 활용했다. 이들 일지에 쓰여진 내러티브는 현장텍스트로서 교육실습생과 학생의 경험이 나타나게 되며, 이러한 내러티브의 의미를 분석한 것이 연구텍스트인데 이를 토대로 연구결과를 도출하면 다음과 같다. 첫째, 교육실습에서 가장 중요한 부분은 수업실습인데, 연구자는 스스로 작성한 실습일지와 학생들이 작성한 학습일지, 그리고 지도교사와의 협의를 통해 수업 전-중-후에 대한 고민과 반성적 사고할 수 있었다. 둘째, 연구자는 내러티브 탐구를 통해 예비교사로서의 한계를 경험하기도 하였지만, 그것은 점점 자신의 교직관을 재정립하게 되는 기제로 작용하였다. 셋째, 연구자는 실무실습이 수업실습에 비해 상대적으로 덜 중요하게 다루어지는 경향을 경험하였다. 그러나 이것은 교육실습을 통해서만 얻어질 수 있는 현장경험이므로 보다 실질적이면서도 비중 있게 이루어질 필요가 있음을 느꼈다. 마지막으로 연구자는 교육실습 초기에는 이론과 실제가 분리되고 있는 듯한 느낌을 받았지만, 내러티브 탐구를 통해 이는 실제로 분절적인 것이 아니라 경험을 통해서 이론을 확인하고 재수정하는 과정임을 깨닫게 되었다. 이러한 측면에서 볼 때, 교육실습에 대한 내러티브 탐구는 교육실습생자신의 경험을 이야기하고 또 이야기하는 과정 속에서 실천적 지식을 체득화하는 계기가 된다는 점에서 의의가 있다고 할 수 있다. The purposes of this study is to apply narrative inquiry to examine the experiences and its meanings that the student (geography) teacher goes through during student teaching. Narrative can be used to express individual experience excellently. So this study collected the student teacher’s teaching journal and students’ learning journals and analyzed their narrative as educational experiences. Narrative written in these journals is a field text showing the student teacher’s experience and students experiences. Research text is to analyze narrative written in the field text to examine meaning of the student teacher’s experience. The results obtained from research text can be summarized as follows: Firstly, a researcher as student teacher could do reflective thinking of teaching through narrative inquiry of the student teacher’s teaching journal, students learning journals and adviser’s comments. Secondly, though the researcher experienced limitations as the student teacher though narrative inquiry, it became gradually positive materials for him or her to be a good teacher. Thirdly, the researcher experienced that an administrative work was apt to be treated less importantly than the student teaching. But the researcher felt that this had to be treated more practically because this could be an experience only through the student teaching. Finally, though the researcher felt that the educational theory and practice was separated in the beginning of the student teaching, he or she thought gradually that it was to identify and to revise the theory through experience. Therefore, narrative inquiry of student teaching means that it is for the student teacher to obtain practical knowledge through the process of telling and retelling of his experience.

都市下層社會硏究에 있어서 貧困의 文化論的 視角

權哲賢 東亞大學校 大學院 1987 大學院論文集 Vol.12 No.-

This study is designed to serve the following two purposes. As its title indicates, the first objective is to analyze and review a particular analytical perspectives, what is called the theory of 'Culture of Poverty' which Oscar Lewis, its foremost advocator, developed in the study of lower class in urban community. The second is to describe the various methodologiclal perspectives on the study of lower class in urban community not from the microscopic, individualistic viewpoint but also the macroscopic, socialstructureal one. In this connection, this paper concentrated all efforts to classify the kinds of appraches and perspectives, and to clarify the main stream of each approaches, and then, analyzed the basic propositions of logical sturcturing and the essential epistemological framework of the theory of 'Culture of Poverty' based on subculture concept for the preparation of a new ground to refine Oscar Lewis' perspectives. The general outline of this study is as follows: After tracing briefly the gists of the genealogy of problem discussed, this paper descried the background of problem conciousness and the reason why the theory of'Culture of Poverty' is the most necessary part for recent developement in the study of lower class in urban community especially in connection with the situation of developing countries, as an introduction in chapter Ⅰ. In chapter Ⅱ, this paper extended a more detailed discussion on the concept and key characteristics of 'Culture of Poverty' In this thesis, what is conserved witness was the strong points of this concept in the study of lower class in urban community. In chapter Ⅲ and Ⅳ, this paper reviewed in depth the disputes surrounding the theory of 'Culture of Poverty', namely the problems of validity of cultural perspective and the problems in practical application of the concept of culture. The utility criteria of the theory of 'Culture of Poverty' was the subject matter of chapter Ⅳ. Finally, in chapter Ⅴ, we dealt with the conclusion of this study as follows: In spite of many criticisms are directed the theory of 'Culture of Poverty', in so far as this concept can be used the categorization of slum, the utility of the perspectives on 'Culture of Poverty' in the study of lower class in urban community is more increased at all points.

권태봉,이정선,우영국,이명헌,정철원,주진순 한국식품영양학회 1999 韓國食品營養學會誌 Vol.12 No.1

위암발증의 원인을 밝히기 위하여 설문조사를 통하여 강원도 화천군에 거주하는 주민들의 일반사항, 생활습관 및 영양섭취실태와, ELISA법으로 Helicobacter pylori 감염률을 조사하였다. 조사 대상자는 40∼69세까지의 지역주민 169명으로 남자 79명, 여자 90명이었으며 그 결과는 다음과 같다. 조사 대상자의 학력은 65.7%가 초등학교 이하였으며, 월수입은 60%가 50만원 이하였다. 대상자의 62.7%가 농업에 종사하였고 자녀수는 64.3%가 3∼5명이었으며 대상자의 34.5%가 흡연을 하고 있었고 68.4%가 음주를 한다고 대답하였다. 대상자의 전체 평균신장은 156.7㎝로 여자는 150.1㎝, 남자는 164.4㎝ 이었다. 평균체중은 61.1㎏으로 여자의 체중은 57㎏, 남자는 65.7㎏이었으며 BMI는 전체 평균 25.5%로 여자는 24.8%, 남자는 20.1%이었다. Helicobacter pylori의 감염률은 전체 조사대상자의 66.3%이었으며, 여자의 67.7%, 남자의 64.6%가 감염되었고 연령별로는 40대의 70%, 50대의 62.2%, 60대의 69.4%가 각각 감염된 것으로 나타났다. 일상 생활 요인에 따른 Helicobacter pylori의 감염률은 흡연의 정도가 심하고 학력이 낮으며 월수입이 낮을수록 높은 경향을 보였다. Helicobacter pylori의 감염여부에 따라 감염자와 비감염자의 영양섭취량을 조사해 본 결과 비감염자는 감염자와 비교해서 에너지, 총단백질, 동물성 단백질, 칼슘, 비타민 C 섭취량이 높은 경향을 보였으며 철분과 niacin의 섭취량은 낮은 경향을 보였다. To examine the relationship between the casual infection of gastric cancer and lifestyle and nutritional status, we surveyed 169 persons, 90 females and 79 males, aged 40∼69 years from June 7 to June 14, 1997, in Whachon area, Kang-Won Do, Korea. For this purpose, we investigated Helicobacter pylori infection and identified the effect of sex, age, smoking, alcohol consumption, economic status, occupation, life-style and food intake on Helicobacter pylori infection. Helicobacter pylori status was evaluated using an enzyme-linked immunosorbant assay(ELISA) for anti-Helicobacter pylori immunoglobulin G(IgG). Helicobacter pylori infection was present in 66.3% of total subjects, namely, 67.7% of female and 64.6% of male and its prevalence increased with smoking, low education level and low monthly income. Energy, total protein, calcium and vitamin C intakes in the negative Helicobacter pylori infection group were higher than those in positive Helicobacter pylori infection group. However iron and niacin intakes were lower in the Helicobacter pylori negative group than in the positive group.
