      • 英語 子音의 變異音에 關한 硏究

        金在明 忠州大學校 1982 한국교통대학교 논문집 Vol.15 No.2

        Language, as we know and use it, is the Spoken tongue, the normal means of face-to-face Communication. The study of a language begins, then, with a study of its spoken form. its sound and sound system. Accordingly the writer tried to analyze the spoken form of English consonants and to find out its variants for practical Pronunciation. Before we attempt to analyze the speech sounds, we will need to recognize and understand the process or method by which we can isolate the different sounds of a language. This method is based on a recognition of the phone mes of a language. A Phone me may be defined as a sound that is significantly different from the other sounds of the language. This then must be our first concern. Once we can recognize and identify these significantly-different sounds, our task of analyzing the speech sound is to seperate these phonemes into varieties of allophones of each Phoneme, because a phoneme is not an actual sound but a theoretical sound (the sound concept or the sound class). Allophones are known as different varitties of the same Phoneme. They are the actual pronunciation we use and they do not contrast significantly from each other. According to this processing criterion which the writer himself established, the writer discussed the English consonants as follows: 1. classification of English consonants 2. discriptions of consonantal phonemes with information as to their articulation and usage 3. information as to Stop sounds in the matter of their allophones or phonetic variants 4. information as to Fricatives in the matter of their allophones or phonetic variants 5. information as to Affricates in the matter of their allophones or phonetic variants 6. information as to Nasals in the matter of their allophones of phonetic variants 7. information as to Laterals in the matter of their allophones or Phonetic variants 8. information as to Glides in the matter of their allopones or phonetic variants will be useful to be able to recognize each of them when you hear it. The writer hope that with a knowledge of this kind, you are capable of understanding the actual sound stucture of the English consonants as they are spoken and heard.

        독일어 동사체계에서 불규칙동사가 유지되는 이유

        김재명 한국독어독문학회 1996 獨逸文學 Vol.61 No.1

        In der vorliegenden Arbeit wird untersucht, warum sich starke Verben gegenu¨ber schwachen gut behaupten ko¨nnen, obgleich in der Sprachvera¨nderung nicht wenige starke Verben in die Gruppe der Schwachen u¨bergetreten sind, diese U¨bertretung immer noch nicht abgeschlossen ist und neue Verben immer schwach flektiert werden. Das Tempus wird bei den starken Verben durch die Inflexion und die Endungen ausgedru¨ckt. Die schwachen Verben dagegen unterscheiden Pra¨t. und P.P. durch ein Dentalsuffix und die Endungen. Hier stehen sich also ein modifikatorischer und ein Suffixmarker gegenu¨ber. Nach Mayerthaler (1981) werden normalerweise solche Paradigmen bevorzugt, die nach dem Prinzip $quot;eine Funktion - eine Form $quot; entsprechend aufgebaut sind oder Paradigmen, bei denen konstruktioneller Ikonismus vorliegt: Was semantisch $quot;mehr$quot; ist, wird durch ein $quot;Mehr$quot; an formalen Mitteln symbolisert. In diesem Sinne sind bei der Symbolisierung die starken Verben sta¨rker markiert als die schwachen. Bei allen innermorphologischen Vera¨nderungen, in denen sta¨rkere und schwa¨chere markierte Formen miteinander konkurrieren, dominiert die weniger markierte Form. Das hat zur Folge, daß viele starke Verben entweder schon schwach konjugiert werden oder wenig bzw., gar nicht gebraucht werden und dadurch absterben. Da die schwachen Verben aufgrund ihrer ho¨heren absoluten Typenfrequenz gegenu¨ber den starkers Verben die dominierende Struktureigenschaft stellen, ko¨nnten wir nach Wurzel (1984) fu¨r das deutsche Verbalsystem vorheragen, daß immer mehr starke Verben sich die Bildungstypologie der schwachen Verben aneignen. Dennoch treffen wir in der Alltagskommunikation auf das Pha¨nomen, daß die starkers Verben relativ ha¨ufig auftreten. Als Grund dafu¨r nennt Werner (1977, 1987), daß man statt ha¨ufiger verwendeter komplexer Strukturen einen ferti gen und kurzen Ausdruck mo¨chte. Das ist beim kommunikativen Verfahren o¨konomischer. Die Belastung in der Kompetenz, die Lern- und Geda¨chtnisarbeit lohnt sich, weil darn die Sucharbeit nach einem geeigneten Komplex entfa¨llt und sich Artikulations-, U¨bertragungs- und Entschlu¨sselungsarbeit spart. Fu¨r seltener beno¨tigte semantische Komplexe jeweils einen fertigen Ausdruck zu haben, belastet aber das Geda¨htnis sehr und stellt einen hohen Lernaufwand dar. Das ist der Grund, warum Suppletivformen nur bei den wenigen, ho¨chstfrequenten Wortformen o¨konornisch sind Diese Suppletivformen zeigen viele unregelma¨ßigen Verben und in gewissem Sinne auch all die starken Verben. Die absolute Zahl der starken Verben ist verschwindend gering im Vergleich zu den schwachen Verben, aber ihre relative Ha¨ufigkeit im flieBenden Text ist u¨berraschend. Das ist der Grund, warum die starken Verben nicht ganz absterben und sich noch gut gegenu¨ber den schwachen behaupten ko¨nnen.

      • 학술적 기업가의 R&D 성과이전 위험의 효과적 관리

        김재명 한국산학경영학회 2003 산학경영연구 Vol.16 No.-

        R&D 성과이전은 좁은 의미의 기술이전 형태이다. 본 연구는 기술개발 아이디어 탐색으로부터 시장진입에 이르는 R&D 성과이전을 효과적으로 수행하는데 유용한 관리시스템의 구성을 연구하였다. 이를 위해 본 연구는 기술이전의 특성과 성공요소를 분석하고 실험실 연구결과를 사업화 하는 학술적 기업가의 실험실 창업프로젝트의 수명주기를 7단계로 구분하고 사례연구를 통해 위험유형을 각 단계별로 탐색하였다. 이를 바탕으로 학술적 기업가의 R&D 성과를 성공적으로 이전하기 위한 전략으로 마케팅 지향적 사고, R&D 참여 당사자간 역할 명시, 학술적 기업가의 역동적 리더십발휘 시스템 구축, R&D 성과이전 관리시스템 구축, 그리고 프로젝트 위험관리기법의 사용 등을 제시하였다. The transfer of R&D performance is the technology transfer in a narrow sense. This study aimed at forming the effective managerial systems of the transfer of the academic entrepreneur's R&D performance. For this purpose, this study analysed the characteristics and success factors of R&D performance transfer based on the theory of project life cycle. This research classified the life cycle of academic entrepreneurs' R&D projects into six stages. And the risks associated with the transfer process was categorized using the case study about the establishing processes the mineral-related small firms. Especially, the risk of the technology transfer was investigated by the R&D project implementation stages. Based on this results, this paper suggested the strategic system such as the marketing-oriented thinking, the clear-cut statement of the role among the stake-holders of the R&D and commercialization processes, the dynamic system of the academic entrepreneurs' leadership, the formation of the transfer management system, and the usage of project risk management techniques.

        임시 저장공간으로써 플래시 SSD의 정렬과 해시 성능 분석

        김재명,이상원,문봉기 한국정보과학회 2008 데이타베이스 연구 Vol.24 No.3

        The densities of flash memory chips have been doubled for the last ten years, and it is estimated this trend will persist for the next five years. According to the trend, flash SSDs with price competitiveness can be used for database server in the near future. A flash SSD can process random read operation almost thousand times faster than a hard-disk, but its random write operation is slower due to its characteristic cannot overwrite data on the same place. In this reason, the database system using flash SSDs for ordinary tablespaces can be slower than that using hard disk drive in some conditions. In this paper, we compare a flash SSD with a hard-disk as a temporary tablespace medium and analyze IO patterns when we perform major database operations such as an external-sort, sort-merge join, and hash join. We also redefine an optimal IO unit for an external-sort with a flash SSD including execution time in various IO units and buffer sizes. 지난 10년간 플래시메모리의 집적도는 매년2배씩 증가하였고 이 성장은 앞으로 5년간 지속될 것으로 예측되며 곧 하드디스크를 대체할 경쟁력을 가질 것으로 보인다 플래시 SSD는 하드디스크와 달리 기계적인 지연이 없어 랜덤읽기 연산을 빠르게 처리하는 반면 한번 데이터를 쓰면 덮어쓰지 못하여 랜덤쓰기 성능이 크게 떨어져 데이터베이 스시스템의 일반 테이블공간에 적용할 경우 성능이 저히될수 있다. 이 논문에서는플래시 SSD를 상용데이터베이스 서버의 임시테이블 공간에 적용하여 성능이 크게 향상됨을 실험을 통해 확인하고,IO패턴을 분석하여 플래시 SSD에 적합함을 보인다 더불어 플래시 SSD를 활용하는 경우 최적의 IO단위가 바뀌어야하고,버퍼 공간 또 한크게 절약할 수 있음을 보인다
