종합적 유해생물 관리(Integrated pest management)라는 용어가 최초로 제기된 것은 30년 전의 일이었다. 물론 그 기원은 방제에 있어서 생태학적 지식이 기초가 되어야 함을 주장하기 시작한 19세기 후반이었다. 그 후 종합적 유해생물관리의 개념은 해충 뿐 만 아니라 식물병이나 잡초 등 유해 생물 전반에 걸쳐 다양한 발전을 거듭하여 왔으며 그 철학은 식물보호학의 기본으로 확고한 자리를 잡게 되었다. IPM의 개념은 현재 널리 인식되어 있으나 그 개념의 내용이 다면적이기 때문에 연구자나 기술자들 간에도 상당한 혼란이나 오해가 있어 왔다. 본 논문은 이와 같은 이론상의 혼란을 정리하고 IPM의 이념과 기술개발 간에 존재하는 괴리를 해소하려 노력 하였다. 이러한 측면에서 개념 발달의 역사적 배경과 개념의 기본이 되고 있는 EIL의 개념을 설명하여 기본개념의 이해를 돕고 관리 수단의 합리적이고 효율적인 적용에 필수적인 해충 개체군 생태학과 관련 표본조사법과 밀도변동동태를 논하여 이론발전을 위한 중요한 연구 방향을 논하였다. 한편 IPM의 이론이나 실험적 연구가 아무리 발전하여도 IPM은 과학이기 이전에 기술이기 때문에 그것을 사용하는 현장의 조건에 맞는 것이어야 하며 그러기 위해서는 사용자인 농민에게 신속히 전달되어야 하며 현재와 같은 다양화된 농업생산 체제에서는 농민각자의 자발적 참여가 중요하다고 생각되며 우리나라 병해충 발생예찰 체제와의 관계에 대하여 단견을 피력하였다.

This paper investigates morphological theory as an intellectual framework for research and design. The first part of the paper will review morphological studies in the fields of urban geography, urban planning and architecture, particularly in England from the 1940s to the 1980s. While urban geographers and planners were concerned primarily with town plans, building forms and land use, architectural theoreticians were more interested in the topological relationship between urban and architectural space. The underlying premises and principles of these two approaches will be reviewed. The second part of the paper will focus on typology in Europe and North America. The reinterpretation of typology by Italian architects helped to bridge the gap between individual elements of architecture and the overall form of the city. However, typological theory became less accessible in post-war England and the United States. After 1980, the debate on typology became muted by the onset of vague notions such as functionalism, bio-technical determinism, and contextualism. This paper will propose a redefinition of morphology as a heuristic device, in contrast with the dichotomic view of urban morphology and architectural typology. Morphology will be shown to combine the geometrical and topological; the intentional and accidental; the real and abstract; and a priori and a posteriori. The last part of the paper discusses the lack of comparative theories and methods surrounding the physical form of architecture and the city by Korea commentators. Empirically rooted facility planning, non-comparative historical studies, and iconographic criticism emerged as a central preoccupation of architectural culture between the 1960s and 1980s, a time when international debate on architecture and urbanism was most intense. This paper will give consideration to the built environment as a dynamic physical entity and space as an epiphenomenon of daily urban life, such that collaboration between urban designers, architects, and landscape architects is seen as both beneficial and necessary.

Studies on western art in Korea has been caught in a dilemma that they could deal with only those things which had been arranged according to their ‘historical generalization’ in their contexts because of the bounds of time and space. It is not trivial that such conditions affect art studies in Korea. Access to the original texts and to their contexts of production is so restricted that the studies on them are prone to be superficial. And it is not independent on the politics of Korean art scene. Such factors are on the background of Korean art’s excessive ‘assimilation or accordance’ with western art. The domestic studies on western art history and art theory have failed to notice the differences in context and Korean art has simply mediated or reproduced the restricted information by those studies. Also the studies on western art in Korea have been made use of as a justifying method of one’s own academic domains. In such situations we should lead the studies on western art history and western art theory to a more reflective direction and confirm that the studies should not have any privileges of the realities. And we should try to reform a scholarship which participates in our life and existence. The field of domestic studies on western art history and western art theory should free itself from the invention of objectivity or the neutrality of mechanical reading and turn its eyes to the realities of life where events happens. Constantly suggesting which way Korean art and world art should go has to be the field’s new coordinates.

EPC seeks to minimize variability by transferring the output variable to a related process input(controllable) variable. In the case of product control, a very reasonable objective is to try to minimize the variance of the output deviations from the target or set point. We consider an alternative EPC model with first-order autoregressive disturbance.

본 논문에서는 납삽입 적층 고무베어링의 비선형 모델링에 대해 신경망 이론을 적용한 수학적 모델링 기법을 제안하였다. 신경망 모델의 수치검증을 위해 납삽입 적층 고무베어링이 설치된 프레임 축소모델의 진동대 실험 자료가 사용되었는데, 제안된 신경망의 학습 및 예측을 위한 하중 자료로써 백색잡음과 세 종류의 지진파를 선택하였다. 지진파의 경우 PGA의 세기를 달리하여 신경망 모델의 계산정도를 고찰하였다. 그 결과, 납삽입 적층 고무베어링의 전단변위가 신경망의 학습 영역을 벗어나지 않는 경우 실험결과의 복잡한 이력곡선을 잘 추종하였고 신경망 이론에 의한 비선형 모델링 기법이 유용하게 활용될 수 있다는 가능성을 확인할 수 있었다.

본 연구는 우리나라 국립공원의 대표적 자연해설시설인 탐방안내소 중 계획에 의해 조성ㆍ운영중인 내장산국립공원 내장사지구 탐방안내소와 북한산국립공원 정릉지구 탐방안내소를 대상으로 기능평가를 통한 이용활성화 방안제시를 목적으로 하였다. 국내외의 문헌연구를 통해 탐방안내소의 개념 및 기능, 유형 등을 파악하고 McManus의 커뮤니케이션 이론을 중심으로 탐방객에 의한 이용 후 평가를 실시하였다. 총 5단계에 걸친 평가 결과 탐방안내소 이용자들은 탐방안내소를 이해하기 위한 충분한 관람시간을 갖지 못하였으며 편의시설과 안내시스템의 부족으로 올바른 이용이 이루어지지 않았다. 전시내용에 대한 관람성향과 전시 내용의 이해도 부문 역시 전시물과 탐방객과의 원활한 커뮤니케이션이 이루어지고 있지 않음을 알 수 있었다. 이런 문제점들의 개선방안으로는 첫째, 탐방안내소 홍보 및 안내사인 보완 둘째, 다양한 계층을 고려한 전시관별 특성화와 차별화 된 전시연출 셋째, 각 전시내용들이 각 탐방객들의 사회적 경험과 연관되도록 하며 넷째, 전시주제에 맞는 전시매체의 적극적 활용이 필요함을 제안하였다.

Even though performance-based language tests are often multivariate by design, previous validation studies have analyzed the dependability of ratings of such tests within univariate analytic frameworks. In an attempt to address this limitation, the present study investigated the dependability of judgements made based on ratings of a German speaking test using a multivariate generalizabilitiy theory (MGT) analysis. Data obtained from 88 students were analyzed in G- and D-studies of a two-facet crossed design. A D-study with two raters and two tasks supported the high dependability of the ratings and the placement decisions made at the pre-determined cut scores. An optimization analysis of the measurement procedure suggested that the desired level of dependability of ratings has already been achieved by the use of two raters and two tasks. The MGT analysis also generated other useful information about the convergent/ discriminant validity of the five subscales. Specifically, the universe score variance-covariance matrix obtained from the D-study showed that the underlying subscales were interrelated but distinct. Furthermore, the analysis of effective weights of the scales revealed that the Grammar subscale played the dominant role in the composite universe score variance.

Kim, Hyesouk. 2004. Theories and Developments of Sociolinguistics. The Sociolinguistic Journal of Korea, 12(1). The purpose of this article is to understand a current status of sociolinguistics by reviewing previous studies and attempting to see the future of the discipline as linguistics. As Milroy and Milroy (1990:485) have defined, sociolinguistics is "the study of language as it is used by real speakers in social and situational contexts of use." It has four characteristics. (1)Those who study sociolinguistics are linguists but they have great interests in adding social variables to pure linguistics. Sociolinguists believe that criteria of correct language usage be based upon not only pure grammatical standards but also societal norms in terms of its relevance and general acceptance. (2)The goal of sociolinguistics is to identify a co-variance between language and society and to establish a theory of language performance. (3)Sociolinguistics regards synchronical and diachronical traits as an identical frame. (4)Sociolingustics pays attention to language usage in societal contexts and extends language competence, which is the main subject of pure linguistics, to communicative competence. D. Hymes predicts that the core areas of linguistics is actually sociolinguistics and, thus, the prefix 'socio' will not be necessary. Although we still have that prefix, it is true that sociolingusitics has already had its own identity and is growing rapidly as an independent discipline. In conclusion, this paper argues that sociolinguistics will receive more attention from linguists and play a key role in linguistics by explaining variation in language more systematically, and by interpreting and eliminating language conflict in everyday life.

Final disposal of radioactive waste generated from Nuclear Power Plant (NPP) requires the detailed information about the characteristics and the quantities of radionuclides in waste package. Most of these radionuclides are difficult to measure and expensive to assay. Thus it is suggested to the indirect method by which the concentration of the Difficult-to-Measure (DTM) nuclide is estimated using the correlations of concentration - it is called the scaling factor - between Easy-to-Measure (Key) nuclides and DTM nuclides with the measured concentration of the Key nuclide. In general, the scaling factor is determined by the log mean average (LMA) method and the regression method. However, these methods are inadequate to apply to fission product nuclides and some activation product nuclides such as 14 and 90 . In this study, the artificial neural network (ANN) method is suggested to improve the conventional SF determination methods - the LMA method and the regression method. The root mean squared errors (RMSE) of the ANN models are compared with those of the conventional SF determination models for 14 and 90 in two parts divided by a training part and a validation part. The SF determination models are arranged in the order of RMSEs as the following order: ANN model

Pulsed wire evaporation (PWE) method is known as the promising production-technique for nanopowders. In this study, we developed and modified the previous single wire explosion equipment to the simultaneous two-wire explosion one for the fabrication of alloy or mixture of nano metallic powder. First of all, both the theoretical and empirical background of pulsed wire explosion of single wire were summarized, and compared with our experimental results for Cu and Al single wlre explosion. After then, the simultaneous wire evaporation equipment was designed, constructed, and tested. The current and voltage behavior were well matched between the calculated ones from the circuit equations, and the experimental results from simultaneous explosion of Cu and Al wire.

This paper focuses on the similarities and differences between Robert Browning's dramatic monologue and W. B. Yeats's mask theory. Even though two poets were not contemporaries, it is very interesting that they show some similarities in poetic skills and subjects. Unlike Romantics revealing a poet's subjective feeling directly in their poems, Robert Browning created the dramatic monologue to develop the field of the objective expression. In his “dramatic monologue,” a character instead of the poet utters the speech that makes up the whole of the poem, in a specific situation at a critical moment. This person addresses and interacts with other people and we know of his presence, as well as what they say and do, only from the clues in the discourse of the single speaker. In his “My Last Duchess” the Duke is negotiating with an emissary for a second marriage, and the reader can know the speaker's cruel character and intentions. In his “Andrea Del Sarto,” though Andrea was one of the greatest painters in the Renaissance period, he was a failure as an artist because of his artistic passion and indomitable spirit. Excusing his artistic frustration, he once more tries to believe his wife's lies. When Yeats entered art school in Dublin in 1884, he was an enthusiastic reader of English poetry, especially Browning. Yeats was an admiring reader of Browning's poetry, and Browning was one of the nineteenth-century forefather poets of Yeats. He explored, as Browning did, the themes of creative men divided within themselves and struggling to unify their inspirations toward love and intellect, aesthetic contemplation and heroic action. In this process, Yeats developed the concept of masks from the other self in contrast to the natural self perceiving a man as the conflicting existence between subjectivity and objectivity. In his doctrine of mask, Yeats provided a formal aesthetic for the poet's need to speak dramatically through the masks of other personalities; Browning had long practised dramatic poetry in principle in which he donned the masks of personalities totally unlike his own. Browning tended to hide his interests behind the masks of his characters, whereas Yeats more openly voiced a variety of mystical and antithetical thoughts. Yeats happened to find an occasional, almost incidental similarity of language and a shared attitude toward the sources of poetic inspiration with Browning's. By 1929, when he was sixty-four years old, rewriting and revising his poetry with an eye to a collected edition, he announced that he would be turned from Browning. Yeats was an appreciative reader of the older poet, but the great achievement of Yeats's poetry transformed and transcended the influence of Browning.

구조물은 지진, 풍랑 등과 같은 외부의 충격에 대해서 노출되어 있기 때문에 대규모의 피해가능성이 항상 존재한다. 이러한 외부에 대한 충격흡수 장치는 여러 가지가 있다. 이러한 기구 중에서 널리 사용되고 있는 것이 기계적 에너지를 소산시키는 유압 감쇠기이다 본 논문에서는 유압 감쇠기의 단점을 보완하고 보다 효율이 높은 감쇠기를 나노기술을 응용하여 새로운 감쇠기에 대한 기초적 이론연구를 하였다. 새로운 감쇠기는 내부에 점성 유체 대신에 무기재료의 입자를 유체와 혼합하여 사용하였고 오리피스를 생략함으로 해서 보다 간단한 구조로 설계하였다. 나노 단위 기공에서의 유동 현상을 설명하기 위해서는 기존의 유체역학에 대한 지배방정식 및 가설들이 더 이상 적용이 되지 않는 단점이 있다. 본 연구에서는 지금까지 명확하게 규명되지 않았던 감쇠기의 열 발생, 나노 유동, 그리고 에너지 소산에 대한 이론적 해석을 수행하였다. 그리고 다공 입자 구조에 따른 에너지 소산에 대한 영향을 모델링하여 조사하였다. 감쇠 효과를 검토하기 위해 기존의 유압 감쇠기와 에너지 소산효율을 비교하였다. 또한 감쇠 효율을 수치적인 해석결과와 실험 결과를 서로 비교하여 검토하였다.

This study suggests a practical analytic method, by which one can analyze tonal music. The essay begins by testifying the validity of Rameauian harmonic theory and of traditional harmonic analysis by Roman numerals. The analytical limit which the traditional methodology of the harmonic analysis poses is supplemented and combined with the theoretical strengths that Schenkerian theory provides. In contrast to the conventional harmonic analysis by Roman numerals, which focuses exclusively on local levels of the chord to chord, what I call the macro-analysis, in which the individual labels of each chord are jointed through brackets under the chord symbols, incorporates a deep understanding of the harmonic functions of each chord and of the musical contexts and the harmonic syntax that the chords create. The examination of the tonal harmony from a Schenkerian point of view serves as a basis for the application of the eclectic methodology, the dialectical result of the Rameauian and Schenkerian theories, to tonal music. Excerpts from Schubert's Lied, Nact and Tra¨ume and Chopin's Nocturne in A^(b) major, Op. 32, no. 2 are analyzed both by the macro-analytic technique and by the Schenkerian analytic method. The paper reveals that the two analytic methods lead to quite similar analytic results.
