Coastal states are adopting maritime boundary delimitation as their primary maritime policy because maritime jurisdiction directly relates to vast economic interest. This becomes specially important and sensitive when complex maritime boundary issues are involved between neighboring coastal states. China has not actively carried out nor declared maritime boundary delimitation until recently with any country except Agreement between China and Viet Nam on the demarcation of the territorial water, the exclusive economic zones and the continental shelf of China and Vet Nam in the Gulf of Tonkin on 25 December 2000 (hereinafter, the Gulf of Tonkin Agreement). The principles that governs maritime boundary delimitation are to consider primarily an agreement between States concerned, however, if no agreement can be reached, all relevant circumstances are considered to achieve an equity between concerned States. Relevant circumstances are length of coastline, form of coastline, existence and position of island or islands, speciality of geology/topography, and factor of economy and deffnce. Factors which sinologists are considering in regard to continental shelf delimitation of the Yellow Sea are as follows; i) geographical factor, ii) geological factor, iii) topographical factor, iv) environment and ecological (factor, v) historic interest, and vi) social and economic interest. The 'Gulf of Tonkin Agreement' is completed by basically applying the principle of delimitation according to median line which seems that China has adopted the maritime boundary delimitation principle of 'half and half' which was the intention of chinese government. At the same time, China recognized Viet Nam's dominion and sovereign right over the partial exclusive economic zone and the continental shelf of Dao Bach Long Vi in Gulf of Tonkin. This case can be considered as an example of mutual concession or compromise in delimiting maritime boundary for states of concerned.

Structure behaviors resulting from an earthquake are experimentally simulated mainly through a shaking table test. As for large-scale structures, however, size effects over a miniature may make it difficult to assess actual behaviors properly. To address this problem, research on the hybrid simulation is being conducted actively. This method is to implement numerical analysis on framework members that affect the general behavior of the structure dominantly through an actual scale experiment and on the rest parts by applying the substructuring technique. However, existing studies on hybrid simulation focus mainly on Slow experimental methods, which are disadvantageous in that it is unable to assess behaviors close to the actual level if material properties change depending on the speed or the influence of inertial force is significant. The present study aims to establish a Real-time hybrid simulation system capable of excitation based on the actual time history and to verify its performance and applicability. The hybrid simulation system built up in this study utilizes the ATS Compensator system, CR integrator, etc. in order to make the target displacement the same with the measured displacement on the basis of MATLAB/Simulink. The target structure was a 2-span bridge and an RC pier to support it was produced as an experimental model in order for the shaking table test and Slow and Real-time hybrid simulations. Behaviors that result from the earthquake of El Centro were examined, and the results were analyzed comparatively. In comparison with the results of the shaking table test, the Real-time hybrid simulation produced more similar maximum displacement and vibration behaviors than the Slow hybrid simulation. Hence, it is thought that the Real-time hybrid simulation proposed in this study can be utilized usefully in seismic capacity assessment of structural systems such as RC pier that are highly non-linear and time-dependent.

Main theme of this paper is the evaluation of the historical significance of Luciano Baldessari's exhibition works mainly during the Fifties. In order to understand the formal and logical basis of those project, his relationship with the historical Avant-gardes and the consequences expressed in his pavilion projects for the Breda Industrial Company are analyzed. The first part focuses on the influence of Italian Futurism, German Expressionism and Italian Rationalism on the formation and experience of Baldessari during the interwar years. The encounter with these movements determine the interest but also the principles along which Baldessari represents his idea of object, space and place. Specially his professional activities during Fascism would determine his attitude toward political power and the necessity of autonomy in artistic sphere. In the second part, different themes that Baldessari affronted in each project of Breda Pavilions is analyzed. Another important issue regard the historiography of the contemporary architecture. Often, many important works that lies in the threshold of the disciplines such as painting and sculpture and media art were excluded in the history of architecture just because they do not deal with the architectural object. Recently, many elements such as theatrical project and temporary objects are considered as part of urban reality and architecture with acknowledgment of their capacity to create event and situations. Along this thought, not just the reconfiguration on the territory of architecture in present but also the criterion to evaluate the past history of architecture is changing drastically. This study on the pavilions of Baldessari intends to contribute indirectly on the current issue of dominion of architecture, but also to evaluate objectively recent architecture. Consequently, architectural protagonists such as Baldessari and their ephemeral projects would be evaluated compressively in their multiplicity of significance.

Effects of available food on growth of commercially cultured Pacific oysters, Crassostrea gigas in Goseong Bay on the south coast were studied using a numerical model. levels of total protein, carbohydrate and lipid in particulate organic matter in the water column as well as chlorophyll a concentration were determined for estimating total available food for oyster growth. Environmental parameters including water temperature, salinity and total suspended solid were also monitored for the model. Oyster growth was also monitored by means of measuring shell length and tissue wet weight increase on a monthly basis. Simulation results from the numerical model indicated that chlorophyll a is not a good representative of available food for the oysters in Goseong Bay. In contrast, available food in the water column measured by filtration of the organic particles and analyzed in terms of total lipids, carbohydrates and protein was well matched with simulated oyster growth in the Bay which is similar to observed growth. The model also suggested that oysters have relatively low retention efficiency of $50\%$ or less. This result indicates that oysters in the bay utilize only a part of food particle available in the water column, as reported in other studies.

Research has suggested that conventional lightweight concrete can offer durability advantages due to reduced cracking tendency. Although a number of publications exist providing the results of laboratory-based studies on the durability performance of lightweight concrete (with lightweight coarse aggregate) and internally cured concrete (using prewetted lightweight fine aggregate), far fewer field studies of durability performance of conventional lightweight concrete bridge decks in service have been performed. This study was commissioned to provide insight to a highway agency on whether enhanced durability performance, and therefore reduced maintenance and longer lifecycles, could be anticipated from existing lightweight concrete bridge decks that were not intentionally internally cured. To facilitate performance comparison, each lightweight bridge deck selected for inclusion in this study was paired with a companion normalweight bridge deck on a bridge of similar structural type, deck thickness, and geometric configuration, with similar age, traffic, and environmental exposure. The field-observed cracking of the decks was recorded and evaluated, and crack densities for transverse, longitudinal, and pattern cracking of the normalweight and lightweight deck in each pair were compared. Although some trends linking crack prevalence to geographic location, traffic, and age were observed, a distinct difference between the cracking present in the paired lightweight and normalweight bridge decks included in this study was not readily evident. Statistical analysis using analysis of covariance (ANCOVA) to adjust for age and traffic influence did not indicate that the type of concrete deck (lightweight or normalweight) is a statistically significant factor in the observed cracking. Therefore, for these service environments, lightweight decks did not consistently demonstrate reduced cracking.

Coleridge's fame as a poet rests on the achievement of the mystery poems, "The Anceint Mariner," "Kubla Khan," and "Christabel." Coleridge's achievement in "Christabel" goes far beyond what previous critics have imagined. Coleridge is one of a handful of great writers who are included as representatives of androgyny. Throughout his life, Coleridge was accustomed to point out feminine qualities within himself. "Christabel" exemplifies the kind of writing contemporary feminist theories call l'écriture féminine. L'écriture féminine is not necessarily the creation of women but may rather be the works of those who refuse to identify with the father and the laws of paternal discourse. "Christabel" becomes Coleridge's most daring symbolic story. "Christabel" appears in its full significance as a vehicle for some profound insights into the dynamics of relationships between men and women, fathers and daughters. Through her deformity, Geraldine is actually the casualty of her father's hatred of women, and is the embodiment of all its anti-virtual aspects. The poem shows no bitterness against women, only compassion and remorse. Coleridge is sympathetically presenting Christabel's suffering as a woman at the hands of an overmastering man. Also, "Christabel" demonstrates woman power as well. In fact, the one person whose tales have any real effect within this narrative is the ambiguous Geraldine. Geraldine excels at story-telling, at making words act for her. Perhaps, despite the appearance of the surface, in which men hold all the cards, it is in fact women, or the feminine, so necessary to procreation and creativity, who hold sway here. This apparent dominion of the feminine derives at least partly from Coleridge's use of the conventions of that feminine genre, the Gothic romance. L'écriture féminine is a concept defined by its divergence from a dominant cultural norm. One may speculate that the fragmentary state of "Christabel" and "Kubla Khan" is in fact congruent with this mode of writing. If these poems imply a theoretical écriture féminine, they are by definition "incomplete," for completeness is a standard of patriarchal language and culture. More perplexing even than the other "mystery poems," "Christabel" is the true fragment of the three.

급변하는 21세기 지식 정보 사회는 다양한 학문 분야의 영역을 넘나드는 융합 교육을 강조하고 있다. 특히 기존의 과학 기술 중심의 융합 교육에 예술을 추가하여 과학적 창의성과 예술적 감수성이 조화된 인재 양성을 기대하였다. 그러나 대부분 과학 기술 교과 중심으로 STEAM 교육이 활발하게 이루어지고 예술 교과는 단지 보조 수단으로 인식되거나 활용되고 있는 실정이다. 이는 예술 교육이 지닌 교육의 특성과 가치를 교육적으로 활용하지 못할 뿐더러, 피상적인 통합 교육으로 갈 수 있다는 점이 문제이다. 이에 본 연구에서는 예술을 체험하고 창작하는 과정에서 과학, 기술, 수학 등 여러 영역의 지식을 유용하게 활용할 수 있도록 하여, 백남준이 그 당시의 과학기술을 창의적으로 활용하여 예술 영역을 확장한 사례와 같이 교육 프로그램을 설계하였다. 이러한 학습 과정에서 EPL이 학습의 지적 도구이자 매개체로 필수적으로 활용될 수 있도록 프로그램을 개발하였다. 초등학생 5학년을 대상으로 교육 프로그램을 적용한 결과 창의적 성향에 긍정적인 영향을 주는 것으로 나타났다.

Focusing on khotan located in the southern Silk Route which was one of the most important kingdoms in the Tarim Basin this study attempts to examine the changes of costume in Khotan by compar-ing the costumes in the painted panel showing the story of silk princess with the excavated costumes from ancient tombs. Furthermore this study attempts to inves-tigate the impacts of cultural exchange be-tween China and its western neighboring country Eastern and Western Turkestan on costume. Excavated costumes from the Shanpula ancient tomb in the region of Khotan and from ancient Niya in the esat-ern border of Khotan and discoveries from Rawak and Dandan-oilik near by Yotkan the ancient capital of Khotan are exam-ined. Basic Khotan's costume was the two piece style of tops and trousers. Over the basic costume wearing a top wear with half sleeves was popular. Skirt was worn by women. Even though there were many kinds tops were classified into the two types kaftan and tunic. Thouth Khotan maintained a association with China for a long time the style of Khotan costume had imbued to China. Top wear with half sleeves was worn frequently in Khotan. Also in China top wear with half sleeves was worn as over-wear which was called ban-xiu ban-bi bei-zi Costume style of China is covering the body profoundly and wrapping front edge toward the right. The types of chi-nese top wear with half sleeves for exam-ple round-neck·confronting front edge crossing-neck·confronting front edge tu-nic type discord with the traditional chi-nese costume style There were many cas-es that half sleeved top wear was worn as over wear in T'ang dynasty. The phenom-enon was due to the prevalence of 'ho' (foreign) and half sleeved top wear was introduced by the countries to the west of China Khotan. A round neck garment was a general type for the men of cuntries to the westof China. Also Chinese wore round neck garment since South and North Dynasty The type of Chinese round neck garment was not tunic but kaftan. From costume relics and ancient paintings the type of Khotan's round neck garment was tunic which was recorded on the Chinese histori-cal documents as " guan-tou-shan" that is tunic the type of persian costume, Even thgough the painted panel showing the sto-ry of silk princess was made in the it me when Turks was a dominion on Central Asia Khotan's costume style was not changed toward Turk's costume style and remained tunic style.

이 논문은 동아시아적 사유를 통해 경계의 의미에 대하여 접근함으로써 경계 담론의 외연을 확장하고자 한다. 사람에게는 우선 '나'라는 '자기 경계'가 있다. 그 몸 경계 속에 정신활동의 경계가 있어서 타자를 대상으로 여기거나 대상을 그려낸다. 동아시아 문화권에서 원초적으로 경계는 국경, 강계(疆界)를 가리키는데, 그것은 물론 불교의 공(空)의 세계를 나타내기도 한다. 경계는 동아시아 사유에서 '인간의 의식이 향하는 곳'이라는 의미가 중요하게 자리 잡고 있고, 그것은 정치, 사회, 문화, 예술 방면에 걸친 것이어서 그리 단편적이지도 않다. 사람에게 생명이 있는 한, 참으로 다가가지 않으면 안 되는 '경계'도 있고, 정신적으로는 욕망, 의지, 관념이 빚어내는 경계도 있다. '경계' 의미에는 사람의 사물 인식 체계에 관계되는 것도 있다. 눈, 코, 입, 귀, 신체 등 오감의 인식 과정에 의한 경계도 있다. 그런 경우라면 다분히 불교적인 맥락에 기초한 사물 인식 차원에 관한 접근인데, 그 같은 인식 시스템에서 발생하는 '경계'는 궁극적이거나 바람직하지 않아서 탈피하지 않으면 안 되는 것도 포함되어 있다. 이 같은 점에 유의하여 경계의 의미, 인간의 의식이 불가피하게 만드는 경계, 부정적인 인식의 경계 등을 성찰하면서 우리가 진정으로 만들어야 하거나 탈피하지 않으면 안 되는 경계 문제를 이 논문은 접근한다.
