Vocal polyp is one of the representative chronic diseases of vocal folds, and it can be cured by voice therapy and/or laryngeal microsurgery. However, the existing therapeutic methods about vocal polyp are in great demand. The purpose of this study was to evaluate the effect of vocal improvement between laryngeal microsurgery and SKMVTT<SUP>®</SUP>(Seong-Tae Kim's Multiple Voice Therapy Technique), which was designed by the author. We identified 37 patients, who were diagnosed with unilateral vocal polyp, aged from 21 to 62 years(mean age: 46 years). 21 patients were treated by the SKMVTT<SUP>®</SUP> and the other 16 patients were only treated by the laryngeal microsurgery. All patients who were treated by the SKMVTT<SUP>®</SUP>, received 12 sessions of treatment, and were evaluated before therapy and after finishing the 12th session. The patients who were treated by laryngeal microsurgery, were evaluated prior to and at least 8 weeks after surgery. The results showed that the SKMVTT<SUP>®</SUP> produced better results compared to the laryngeal microsurgery alone. The SKMVTT<SUP>®</SUP> produced better results, especially, at the initial stage of voice therapy compared with those of laryngeal microsurgery. In this study, we can suggest that SKMVTT<SUP>®</SUP> may be useful in improving the voice qualities of vocal polyp patients. However, more data should be collected and evaluated to be widely used in other clinics.

The Purpose of this study is, in the analysis of dancings referred in the editorial comment's written by Columnists, to analysis and observe such comments written from 1980 to 1989 concerning the aspect of the overall activity of dancing art, and the analysis covers comments announced through leading newspapers and professional publications. As a result, the analysis of overall activity of dancing art revealed that, in 1980s, it was Controlled by social confusion but it was abundant Renaissance period of dancing culture in quality and quantity. Especially in the Year of 1982, it was twenty Years since Modern Dance was introduced. On the other hand, the performances of foreign dancers invited enhanced the interest and Knowledge of native dancers concerning foreign dancings. In the Year of 1983, traditional Korean dancing was active, and it was continued with creative dancing till middle period of the Year. The activity of columnists was more active in the latter half of 1980s than the former half of 1980s During the period of '86 Asian Game and' 88 Olympic Game, Personal and Group daning, Men's dancing Group were made. As one of the Characteristics of dancing activity performed during this period, we can realize, through and investigation concerning the frequency of the use of terminology, on what columnists put their empahsis, In the Year of 1980 and 1988 ; they put emphasis on Physical factor and In the Year of 1983 and 1988 ; the factor of time and in the Year of 1984 and 1987 ; the factor of space and in the Year of 1981 and 1985 ; Secondary factor and in the year of 1984 and 1986 ; the factor of beauty. As a result of observing these factors horizontally, Expression of physical Factor was emphasized by 37,80 Percents. the next was the factor of beauty by 27,24 percents Secondary factory by 19,36 Percents, the factor of time by 10,08 percents, the factor of space by 5,52 percents. Thus, it was revealed that the dancing of this country emphasis an aesthetical defection and the external factor(Secondary factor) For the improvement of the quality of stage art, it is indispensable for artist to have scientific Philosophy and traditional spirit of Korean art and their right attitude. the amalgamation of folk dancers and ballet dances and the development of accompaniment which is indispensable for dancing art are urgent problems. Dancing will be highly evaluated as an art of stage when all columnists critisize fine art, dancing and other individual art which aesthetical views so that they can break conventional criticism based on impressionism and they can develop scientific criticism.

We have fabricated various solar cells, such as p-n junction p-AlGaAs/p-GaAs/n-GaAs heteroface and p-GaAs/i-(InGaAs/GaAs)/n-GaAs multi quantum well structure solar cells, which art grown by low-pressure metalorganic chemical vapor deposition(MOCVD). The electrical and structural properities of epitaxial layers have been characterized by Van der Pauw Hall measurement and DCXD(double crystal X-ray diffractometry) measurement. Current - voltage (I-V) characteristics have been investigated by curve trace and light source was tungsten-halogen lamp (34.992 mW/cm^(2)). The conversion efficiency of AlGaAs/GaAs p-p-n heteroface solar cell (V_(∝) : 0.62 V, I : 3.2㎃, efficiency : 10.1%) is greater than the simple p-n junction solar cell (V_(∝) : 0.59 V, I : 2.9 mA, efficiency : 9.1%). In the multi quantum well structure solar cell(p-GaAs/i-(InGaAs/GaAs)/n-GaAs), short circuit current (5.5mA) increased a little.

정보통신의 비약적인 발전에 힘입어 멀티미디어 데이터는 언제 어디서든 전송 받거나 공유할 수 있게 되었다. 아날로그 형태에서 디지털의 아날로그를 형태로 빠르게 대체되고 있으며, 디지털로 신호를 표현하는 방법은 기존 사용하여 표현하는 방법에 비해 많은 장점을 가지고 있다. 하지만 디지털로 된 데이터는 언제 어디서든 대단위 복제가 가능하다. 즉, 저작권 침해, 불법 복제 및 배포, 손쉽게 위조할 수 있다는 점이 그것이다. 디지털 영상 정보의 보호를 위해 디지털 영상의 불법적인 내용 조작을 막고, 영상의 소유권을 보장할 수 있는 방법으로 디지털 워터마크(Digital Watermark)가 있다. 디지털 워터마크는 공개키 알고리즘이나 방화벽 등으로 해독된 영상에 대하여 부가적인 보호를 제공한다. 디지털 영상에 대한 저작권 정보, 배포자 정보 그리고 사용자 정보를 영상에 삽입함으로써 훗날 법적인 문제가 발생하였을 때 해결책을 제시할 수 있다. 본 논문에서는 디지털 영상 데이터의 정보 보호를 위해 주파수 영역에서의 웨이브릿변환(Wavelet Transform)을 이용한 이미지 적응 디지털 워터마킹(Image-Adaptive Digital Watermarking) 방법을 제안한다. 이미지 적응 웨이브릿(Image-Adaptive Wavelet)은 영상을 주파수적으로 분해하면서 각 대역들의 공간 영역에서의 정보를 함께 지니고 JND's(Just noticeable difference)을 포함한다. 이미지 적응 웨이브릿의 이러한 특성을 이용하여 다해상도 분해하고, 손실 압축(Loss Compression)이나 필터링(Filtering), 잡음(Noise)등에 크게 영향받는 저주파 성분과 인간의 시각적으로 큰 의미를 갖는 고주파 성분의 특성을 이용하여 워터마크를 삽입한다. Multispectral image is wavelet trans formed and classified into one of three classes considering reference characteristics of the subband with the lowest resolution. Then, for a reference channel which has the highest correlation with other channels, the variable VQ is performed in the classified in the classified intra-channel to remove spatial redundancy. For other channels the CIP is performed to remove spectral redundancy. Recently, aegis of authentication and creator's copyright has become a matter of great concern by the diffusion of multimedia technique and the growth of the internet and the easily duplicated property of digital data. Consequently, many active researches have been made to protect copyright and to assure integrity by inserting watermark into the digital data. In this paper, watermark is repeated through the entire image and adapted to the content of the image.

韓國人의 正義知覺에 關한 硏究

安成浩 大田大學校 1988 論文集 Vol.7 No.1

According to my previous study, egoistic self-interest perceptions appear to expain a relatively small portion of the variance in policy responses. The major portion of the variance in policy responses in expained by the judgments of procedural justice as a dominant determinat in citizens' policy responses. This study is to theoritically develop and empirically test Koreans' justice perceptions. It is understood that the justice judgments subsume some kinds of justice norms as criteria of fairness. Justice norms are social prescriptions of prohibitions that a community uses to create fair relations among its members. Generally, two categories of justice norms have been distinguished : distributive justice norms, i.e., the fairness criteria of the outcomes received; and procedural justice norms, i.e., the fairness criterion of the procedure by which the outcomes are distributed. In this study, four distributive justice norms and a procedural justice norm are considered. The five justice norms argued are : (1) Equality : All community members deserve equal amounts of divisible resources. Alternatively, community members should be required to bear equal burdens when necessary. (2) Need : All needs of community members deserve equal satisfaction. Alternatively, community members should sacrifice equal amounts of satisfaction. (3) Merit : Community members deserve rewards in proportion to what they contribute to the community. (4) Ascription : Community members deserve rewards according to relevant ascriptive traits, such as age, sex, class, region, family connection, or school connection. (5) Procedure :The procedural justice does not seek patterned fair results. Procedural justice can be thought of as pertaining to the perceived fairness of rules which govern policy process. Six rules can be suggested that might be applied when judging the fairness of a procedure : consistency across time and person, suppression of biases, accuracy of information, correctability of a decision, representativeness in a decisionmaking body, and the maintenance of ethical and moral standards. In order to test a set of hypotheses derived from the theoritical model of policy responses developed, survey data were collected through standardized interviews with 313 sample subjects residing in Taejon dity and Taeduk kun during the summer of 1987. Each subject answered 22 questions on a 5-point Likert scale with the aid of an interviewer. The findings of the statistcal analysis of survey data can be summarized as follows. 1. The first issue tested was about the categorization of citizens of value orientations toward distributive justice norms. The results of an oblique rotated factor analysis indicated that the value orientations of citizens toward distributive justice norms tended to be categorized into three areas : equality-related justice norms comprising equality and need, merit norm, and ascription norm. 2. The second issue examined was to ascertain the components of procedural justice judgments of public policies in general. The results showed that consistency across time and person, representativeness, correctability of the decison, ethicality, and accuracy of information are all important in assessing the fairness of the goverment dicisionmaking procedure. In particular, consistency and representativeness among these rules were prominent components citizens used in assessing the fairness of the government process. 3. The last issue was concerned with individual differences in the preferences of distributive justice norms. The results proved that age, sex, and education differences differentiated the preferences of distributive norms. The larger portion of the old tends to prefer ascriptive justice norm whereas the larger portion of the young tends to prefer equality-oriented justice norms. The relative large portion of women appears to follow equality-oriented justice norms, whereas the relative large portion of men appears to follow the norms of merit and ascription. Finally, egalitarian values were found to be linked to education.

恨의 맺힘구조와 力動的 想像力 : <招魂>과 <배따라기>를 중심으로 centered the work of「Chohon」and「Baettaragi」

안성수 제주대학교 1988 논문집 Vol.27 No.1

Summary The purpose of this study was to investigate the chain generative structure of wail and "Han" (a kind of particular korean emotion) in relation to the process of figuration in literary works. For this aim. the writer proposed establishment of concept about lamentation, wail and"Han" since in dealing with the problem concerning "Han" 1amentation and wail as preceding stage of "Han" are generated. The writer defined lamentation as crying which accepts sorrowful situation given asresigned situation, while wail was defmed as an extreme crying which denies that situationand rather has will power and action of overcoming the situation. Therefore, lamentation itself has difficulty m switching over to the smouldering structureof "Han".On the contrary to lamentation, wail that denies the given situation and has wil1of overcollling and transcendence is sublimated to the structure of "Han". The structure of 「Chohon」 and 「Baettaragi」 exammed m this paper uses the amplifying devices of special emotion for the purpose of remforcing tone of wail. This amplifying devices help the smouldering structure to transfer to the solution structure by using thepower of wail roused. The device of rhythln m「Chohon」 and the double frame m「Baettaragi」 function as the amplifier for it· 「Chohon」 is staying on the stage forsearching ways to so1ve the smouldering of "Han". whereas 「Baettaragi」 vents its "Han" through the pattern of wandering throughout character's life. However, these two works can be classified into the type of the slnouldering structureof "Han". As mentioned above, "Han" is fundalnentally a kind of tragic ernㅇ tion originatedfroln the interaction between subject and object and it has three generative structure: byself, by others and by interaction between self and others. 「Chohon」 and 「Baettaragi」,thus, can be called the story of "Han" in the sense that the subject influences the objectand the for ther who will receive that influence again from the latter bears "Han" inhis(her) inner world. Another pomt the writer proposed is on the dynamic principle that transforrns thesrnouldering structure of "Han" into solution structure of it. There are severa1 methodsand process to so1ve "Han": dialectical, sequentia1 prmciples and so on. Because "Han"has an organic and cornplex generative structure, the researcher must consider variety manalyzing the structure of "Han", in「Chohon」 and 「Baettaragi」 the writer explained dynarnics in relation to the dialectical imagination that sublited extreme emotion into "Han".

We studied a extraction and degradation of alginate from seaweed-stems using microorganism DS-02. DS-02 has a maximum growth rate at 30 ℃ and the enzyme has a maximum activity of alginate extraction at 35 ℃. The yield of alginate extraction using DS-02 is about 16.0% for 3.0 hour and molecular weight of the alginate decreased to about 1/8 of initial value after 24 hour extraction. Alginate extraction method by DS-02, compared with general alkali-extraction method, has an advantage of decreasing the molecular weight of alginate during extraction.

인플레이션 목표설정제도에 대한 게임이론적 평가

安聖恩 慶一大學校 1999 論文集 Vol.16 No.1

새로운 통화정책전략으로서의 인플레이션 목표설정제도에 대하여 최근 몇 년 동안 통화정책입안자들이나 화폐경제학자들이 많은 관심을 가졌다. 1990년에 New Zealand의 중앙은행이 인플레이션 목표설정제도를 도입한 이후로, Canada, 영국, Sweden 등의 중앙은행들이 잇따라 도입하였다. 통화정책에 대한 새로운 제도도입으로 이들 나라에 만연하였던 인플레이션이 많이 진정되었다. 이론적인 면이나, 현실적인 성과로 볼 때, 인플레이션 목표설정제도는 1990년도에 성공한 통화정책제도로 보인다. Svensson을 비롯한 많은 학자들이 인플레이션 목표설정제도에 대한 이론적인 분석을 시도하였다. 본 연구는 그 동안의 이론적인 연구결과를 게임이론적인 시각에서 재조명해 봄으로써, 인플레이션 목표설정제도의 성과를 높이기 위한 연구의 방향을 제시한다.
