The effect of powdery mildew infection on the $^{14}CO_2$ assimilation and metabolism of $^{14}C-$assimilates was studied with spring barley cultivars, susceptible Peruvian and adult-plant resistant Asse at the four-leaf stage. No consistent differences between Peruvian and Asse were revealed in $^{14}CO_2$ assimilation and metabolism of $^{14}C-$assimilates in healthy whole plants. In the two cultivars, $^{14}CO_2$ assimilation and translocation of assimilates decreased as the number of infected leaves increased. Despite the same infection intensity, $^{14}CO_2$ assimilation was less inhibited in Asse than Peruvian. Infection reduced the fixation of $^{14}CO_2$ in noninfected fourth leaves of Peruvian more severely than that of Asse. Infection of the lower 3 leaves also inhibited the incorporation of 14 C into carbohydrates such as fructose and glucose in noninfected fourth leaves and their translocation into leaf sheathes, the inhibitions being greater in Peruvian than Asse. In the infected third leaves, there was a reduction of 14 C-activity in carbohydrates, more $^{14}C-$labeled fructose and glucose being retained in Peruvian. The stimulation of $^{14}C-$organic acid synthesis in all plant organs was more pronounced in Peruvian than Asse. Powdery mildew markedly increased the incorporation of $^{14}C$ into amino acids in infected third and noninfected fourth leaves, but reduced their translocation to the leaf sheathes. A greater rise of $^{14}C-$ activity in some amino acids in the two leaves was found in Peruvian than Asse.

Investigated data on Lake Okjeong were used for the simulation of water quality. According to the simulation results, the effective scheme of water quality management on reservoir has been proposed. It has been recognized that the water quality of Lake Okjeong is under eutrophic and mesotrophic condition even though there are seasonal variation. The water quality of lake is mainly affected by the inflow of pollutant load from watershed. Therefore, to estimate and quantify the accurate amounts of pollutants flowing into reservoir is absolutely necessary for the effective management of water quality on Lake Okjeong. When the pollutant load measured during 7 different rainy periods in 1999 was compared with total pollutant load in 1999. TN and TP measured during 7 different rainy periods showed almost 50% of total pollutant load. In case of SS, it was 72.8%. On the other hand, the rainfall amount measured during the 7 different rainy periods was about 17.5% of total rainfall amount in 1999. Release rate of TP shows 11.92 mg/L at fish farm site and 0.2∼1.9 mg/L at monitoring station of water quality on Lake Okjeong, and which is considered to be less than that of other foreign reservoirs under the circumstances of anoxic condition. For the effective management of water quality on Lake Okjeong. WASP5 water quality simulation model has been applied and verified, and the verified model was used to propose the effective scheme of water quality management. In this case, 6 different scenarios were applied, by changing the amount of inflow of pollutant load in each subbasin. The most effective scheme has turned out that pollutant load generated from Imsil and Gwanchon subbasin should be reduced, and the best way to improve the water a quality is to reduce the pollutant load at every subbasin. According to the simulation result, wastewater treatment facility should be located at every subbasin.

The most important issue in providing multimedia traffic on a mobile computing environments is to guarantee the mobile host(client) with consistent QoS(Quality of Service). However, the QoS negotiated between the client and network in one cell may not be honored due to client mobility, causing hand-offs between cells. In this paper, a call admission control mechanism is proposed to provide consistent QoS guarantees for multimedia traffics in a mobile computing environment. Each cell can reserve fractional bandwidths for hand-off calls to its adjacent cells. It is important to determine the right amount of reserved bandwidth for hand-off calls because the blocking probability of new calls may increase if the amount of reserved bandwidth is more than necessary. An adaptive bandwidth reservation based on an MPP(Mobility Pattern Profile) and a 2-tier cell structure has been proposed to determine the amount of bandwidth to be reserved in the cell and to control dynamically its amount based on its network condition. We also propose a call admission control based on this bandwidth reservation and "next-cell prediction" scheme using an MPP. In order to evaluate the performance of our call admission control mechanism, we measure the metrics such as the blocking probability of our call admission control mechanism, we measure the metrics such as the blocking probability of new calls, dropping probability of hand-off calls, and bandwidth utilization. The simulation results show that the performance of our mechanism is superior to that of the existing mechanisms such as NR-CAT1, FR-CAT1, and AR-CAT1.

Needs for Smart Grid development are increasing all over the world as a solution to its problem according to depletion of energy resources, climatic and environmental rapidly change and growing demand for electrical power. Especially decentralized power is attracting world's attention. In this mood a new era for a unit scale of decentralized power environment is on its way in building. However there is a problem to have to be solved in the uniformity of power quality because the amount of power generated from renewable energy resources such as wind power and solar light is very sensitive to climate fluctuation. And thus this paper tries to suggest an energy management method on basis of real time monitoring for meteorological data. In the current situation of lacking in USN-based killer application in Smart Grid field, this paper proposes the USN-based DER management system which collects the meteorological data and control power system througout utilizing wireless sensor network technique this business. This communication technique is regarded to be efficient in aspects of installation cost and tits maintenance cost. The proposed EMS model embodies the method for predicting the power generation by monitoring and analyzing the climatic data and controling the efficient power distribution between the renewable energy and the existing power. The ultimate goal of this paper is to provide the technological basis for achieving zero-energy house.

Studies on the circulation and water masses in the continental shelf break region of the East China Sea are Summerized as follows : 1. The main stream of the Kuroshio flowing north-east near $29^{\circ}N\;Lat\;127^{\circ}E$ tong of the East China Sea in summer is narrow in width. Moving toward east, it becomes twice as wide in Tokora Strait, Japan. 2. In the main stream area of the Kuroshio, the surface Waters in the Upper layer (0-250m) are influenced by the coastal waters of China, and the counter current submerges under the surface water. Therefore, the mixing waters are found in its intermediate layer. 3. Water mass between Amami Island and the continental shelf of the East China Sea consists of main stream water, counter current water, gyration water and mixed water with coastal waters. 4. The maximum velocity of current in this waters was 139cm/sec. The volume transport was estimated approximately as $24.2\;\times\;10^6m^3/sec$. It was less than $33\;\times\;10^6m^3/sec$ in the region between Okinawa and continental shelf of the East China Sea. 5. Surface waters east of $29^{\circ}N\;Lat\;128^{\circ}E$ Long flows toward Amami Island, Okinawa Island, and Hachi Ju San Island, while those west of the region flow toward the Korea-strait, Cheju Island, coastal waters of Kyusyu, and the Pacific Ocean through Tokora Strait. The velocity of the current was estimated approximately as $0.3\~0.5$ miles per hour. 6. The bottom waters in the continental shelf break region flow toward the Korea Strait, Cheju Island and the coastal water of Kyusyu, while that of the continental shelf flows toward the Yellow Sea, 7, The characteristics of the Kuroshio water is changed remarkably by the mixing with the coastal water of China.

지적재산권의 속지주의 원칙에 따라 전통적으로 지적재산권의 침해에 있어서 결과의 발생이 없는 행위지를 침해지로 인정하지 않았다. 어문과 예술작품을 보호하기 위해 1886년 체결된 베른협약(Berne Convention for the Protection of Literary and Artistic Works) 제5조 제1항은 저작자가 베른협약에 따라 보호되는 저작물에 관하여 본국 이외의 동맹국에서 각 법률이 현재 또는 장래에 자국민에게 부여하는 권리 및 이 협약이 특별히 부여하는 권리를 향유한다고 규정하여 내국민대우원칙을 천명하고 있다. 또한 베른협약 제5조 제2항은 저작권의 보호와 향유는 저작물의 본국에서 보호가 존재하는 여부와 관계가 없이, 보호의 범위와 저작자의 권리를 보호하기 위하여 주어지는 구제의 방법은 오로지 보호가 주장되는 국가의 법률의 지배를 받는다라고 규정하여 저작권 침해가 발행한 국가의 법률의 적용을 명시하고 있다. 인터넷과 무선통신 기술의 발달은 저작물을 디지탈 형식으로 실시간에 전세계에 배포하는 것을 가능하게 하였다. 특히 저작물의 인터넷상에서의 배포는 다국적 저작권 침해행위를 야기하여, 저작권자가 다수의 국가에서 저작권 침해소송을 제기하여 판결을 집행하는 것이 필요하게 되었다. 헤이그국제사법회의(Hague Conference on Private International Law)에서 1992년부터 논의되어 온 민사 및 상사사건의 국제재판관할과 외국판결에 관한 협약(Convention on Jurisdiction and Foreign Judgment in Civil and Commercial Matters)에서 채택된1999년의 예비초안(preliminary draft) 및 2001년 외교회의에서 수정된 잠정초안(Interim text) (이하 헤이그 협약 )은 저작권자가 저작권침해행위가 발생한 각 국가에서 저작권 침해행위를 금지하는 소송을 제기할 필요없이, 동 협약의 한 가맹국가의 법원의 저작권침해금지판결을 다른 가맹국가에서도 집행할 수 있는 가능성을 제시해 주는데 의미가 있다. 헤이그 협약 제10조는 불법행위(torts)에 관한 일반적인 재판관할에 관한 규정을 두고 있으며, 저작권침해에 관한 분쟁은 동 조항의 적용을 받는다. 제10조에 의해 당사자는 가해행위지 국가의 법원 또는 결과발생지 국가의 법원에서 소송을 제기할 수 있다. 결과발생지의 경우 제10조 1항 (b)는 피고가 자신의 행위가 본국의 법규에 비추어 동일한 성격의 손해를 초래할 수 있다라고 합리적으로 예견할 수 없었던 경우에 본 조항의 적용을 배제하고 있다. 인터넷을 통한 저작권침해의 경우, 피고가 자신의 국가의 법규하에서 합법적으로 저작물을 웹사이트에 게시하였으나, 그 행위가 다운로딩이 행해진 국가에서 불법인 경우, 피고는 저작권침해를 예견할 수 없었으므로 이에 문제가 제기된다. iCrave TV사건에서, 피고인 캐나다회사가 미국 및 캐나다에서 방송되는 텔레비젼 방송 프로그램을 자신의 웹사이트에 게시하여 이용자들로 하여금 컴퓨터를 통하여 방송을 재시청 할 수 있도록 하였는데 이는 캐나다에서 합법인 반면에 미국에서는 저작권 침해에 해당한다. 피고는 방송 프로그램을 인터넷상에서 재방송하는 것은 캐나다법상 합법이므로 저작권침해를 예견할 수 없었다고 주장하면서, 해당 사이트에 오직 캐나다 거주자만의 접속을 허용하고 미국 거주자의 접속을 제한하는 일련의 Click-Wrap 계약과 스크린 장치를 제공하였다고 주장하였다. 본 사건 피고의 주장을 받아들인다고 가정할 때, 제10조 1항(b)에 의해 원고는 결과발생지인 미국법원의 재판관할을 강제할 수 없을 것이다. 지적재산권을 둘러싼 분쟁에 관한 재판관할과 국제법상의 판결의 승인 및 집행의 통일성을 기하기 위하여 2001년 1월 세계지적재산권기구(World Intellectual Property Organization)가 제안한 WIPO 협약초안(Draft Convention on Jurisdiction and Recognition of Judgments in Intellectual Property Matters)은 헤이그 협약이 재판관할과 판결의 승인 및 집행에 대한 일반적인 접근을 하고 있는 점에 반하여 지적재산권자의 보호라는 측면을 고려하여 지적재산권침해소송에 국제재판관할권을 규정하고 있다. WIPO 협약초안 제6조는 저작권자가 저작권 침해를 막기 위한 합리적인 조치를 취한 국가에서 저작권 침해소송을 피할 수 있다고 규정하고 있다. 따라서 본 조항에 의할 경우, iCrave TV사건의 피고는 미국에서의 저작권 침해소송을 회피할 수 있을 것이다. 이상과 같이 헤이그 협약이 외국판결의 승인 및 집행을 가능하게 하고 있음에도 불구하고, 외국법원의 판결이 다수의 가맹국가에서 집행되지 못하는 가장 큰 장애는 대다수의 국가들이 외국법원의 판결이 공서양속(Public Policy)에 반하는 경우 판결을 승인하지 않는 예외규정을 두고 있기 때문이다. 미국의 경우, Uniform Recognition Act와 Restatement(Third) of Foreign Relations에 따른 공서양속의 예외규정(Public Policy exception)은 외국법원의 판결의 승인을 부인하는 근거가 된다. Yahoo! 사건에서 Yahoo! Inc.의 옥션 사이트를 통해 독일 나치 소장물의 판매가 이루어졌는데, 프랑스 형법상 이는 범죄행위에 해당하므로, 프랑스 법원은Yahoo! Inc.에게 프랑스 이용자가 당해 옥션 사이트에 접속할 수 없도록 모든 가능한 조치를 취할 것을 명하였다. 이에 미국 법원은 프랑스 법원의 판결은 Yahoo! Inc.의 미국헌법 제1 수정(First Amendment)의 언론의 자유(freedom of speech)에 반하므로 판결의 집행을 거부하였는데 이는 공서양속의 예외규정을 보여주는 예이다. 헤이그 협약 제28조와 WIPO 협약초안 제25조 또한 공서양속의 예외규정을 두고 있다. 본 논문은 인터넷과 통신기술의 발달로 야기되는 다국적 저작권 침해사건에서 한 국가의 법원의 저작권 침해금지판결이 다수의 국가에서 승인 및 집행될 수 있는 능성을 헤이그 협약과 WIPO 협약초안 및 미국판결을 중심으로 살펴보았다. 국제적으로 통일된 저작권법이 존재하지 않고 외국 판결의 승인을 부인하는 예외조항과 외국판결의 집행에 관한 각국의 이해관계와 준거법의 해석이 다른 현시점에서 지적재산권의 속지주의를 뛰어넘어 외국법원의 판결을 국제적으로 집행하는 것은 다소 어려움이 있어 보이나 국제적인 집행가능성의 열쇠를 제시하는 헤이그 협약과 장래의 국제조약에 그 기대를 걸어볼 수 있겠다.

Investigated ware the decomposition of mulch paper, weed occurrence, and rice growth and yield in transplanting rice culture with paper mulching in 1996 and 1997. The mulch paper were developed from domestic old corrugated container. In the experiment of 1996 where 25 percent of nitrogen fertilizer was applied as tillering fertilizer at 15 days after transplanting, it took about 28 to 40 days for the mulch paper to reach 50 percent decomposition according to types of mulch paper and fertilizer amount. The decomposition was faster in 18kg N/10a fertilization plot than in 12kg N/10a fertilization plot, and slower in the mulch paper treated with polyamidepolyamine epichlorohydrin resin(PPE) for the reinforcement of wet strength than in the mulch paper without PPE. In the experiment of 1997 where nitrogen fertilizer was not applied at tillering stage and instead 70 percent of nitrogen fertilizer was supplied as basal fertilizer, it took more than 42 days for the mulch paper(PPF treated) to reach 50 percent decomposition. Paper mulching was found to be very effective in controlling the paddy weeds at early stage of rice growth, but the efficacy, of weed control decreased especially in the mulch paper without PPE at later stage of rite growth due to the occurrence of Ludwigia prostrata in 1996. Few weeds occurred even in non-mulched plot without herbicide in 1997, rending difficulties in evaluating the efficacy of mulch paper in weed control, However, it could be deduced from the durability of mulch paper that paper mulching would have had sufficient efficacy of weed control. Rice yield was only 185kg/10a in the plot without mulching and weed control, but 657kg/10a and 771kg/10a in the paper(PPE treated) mulching plot with 12kgN/10a and 18kgN/10a, respectively, in 1996. The paper mulching plot showed rice yield similar to the weed control plot with herbicide in 1997. It would be concluded that paper mulching could ensure effective weed control and as high yield as the conventional rice cultivation with herbicidal weed control if the corresponding amount of basal nitrogen fertilizer is increased instead of omitting the nitrogen fertilizer at tillering stage.

Located on the right side of the third floor of the State Hermitage Museum in St. Petersburg, the "Art of Central Asia" exhibition boasts the world's finest collection of artworks and artifacts from the Silk Road. Every item in the collection has been classified by region, and many of them were collected in the early twentieth century through archaeological surveys led by Russia's Pyotr Kozlov, Mikhail Berezovsky, and Sergey Oldenburg. Some of these artifacts have been presented around the world through special exhibitions held in Germany, France, the United Kingdom, the Netherlands, Korea, Japan, and elsewhere. The fruits of Russia's Silk Road expeditions were also on full display in the 2008 exhibition The Caves of One Thousand Buddhas - Russian Expeditions on the Silk Route on the Occasion of 190 Years of the Asiatic Museum, held at the Hermitage Museum. Published in 2018 by the Shanghai Chinese Classics Publishing House in collaboration with the Hermitage Museum, Kuche Art Relics Collected in Russia introduces the Hermitage's collection of artifacts from the Kuche (or Kucha) region. While the book focuses exclusively on artifacts excavated from the Kuche area, it also includes valuable on-site photos and sketches from the Russian expeditions, thus helping to enhance readers' overall understanding of the characteristics of Kuche art within the Buddhist art of Central Asia. The book was compiled by Dr. Kira Samosyuk, senior curator of the Oriental Department of the Hermitage Museum, who also wrote the main article and the artifact descriptions. Dr. Samosyuk is an internationally renowned scholar of Central Asian Buddhist art, with a particular expertise in the art of Khara-Khoto and Xi-yu. In her article "The Art of the Kuche Buddhist Temples," Dr. Samosyuk provides an overview of Russia's Silk Road expeditions, before introducing the historical development of Kuche in the Buddhist era and the aspects of Buddhism transmitted to Kuche. She describes the murals and clay sculptures in the Buddhist grottoes, giving important details on their themes and issues with estimating their dates, and also explains how the temples operated as places of worship. In conclusion, Dr. Samosyuk argues that the Kuche region, while continuously engaging with various peoples in China and the nomadic world, developed its own independent Buddhist culture incorporating elements of Gandara, Hellenistic, Persian, and Chinese art and culture. Finally, she states that the culture of the Kuche region had a profound influence not only on the Tarim Basin, but also on the Buddhist grottoes of Dunhuang and the central region of China. A considerable portion of Dr. Samosyuk's article addresses efforts to estimate the date of the grottoes in the Kuche region. After citing various scholars' views on the dates of the murals, she argues that the Kizil grottoes likely began prior to the fifth century, which is at least 100 years earlier than most current estimates. This conclusion is reached by comparing the iconography of the armor depicted in the murals with related materials excavated from the surrounding area (such as items of Sogdian art). However, efforts to date the Buddhist grottoes of Kuche must take many factors into consideration, such as the geological characteristics of the caves, the themes and styles of the Buddhist paintings, the types of pigments used, and the clothing, hairstyles, and ornamentation of the depicted figures. Moreover, such interdisciplinary data must be studied within the context of Kuche's relations with nearby cultures. Scientific methods such as radiocarbon dating could also be applied for supplementary materials. The preface of Kuche Art Relics Collected in Russia reveals that the catalog is the first volume covering the Hermitage Museum's collection of Kuche art, and that the next volume in the series will cover a large collection of mural fragments that were taken from Berlin during World War II. For many years, the whereabouts of these mural fragments were unknown to both the public and academia, but after restoration, the fragments were recently re-introduced to the public as part of the museum's permanent exhibition. We look forward to the next publication that focuses on these mural fragments, and also to future catalogs introducing the artifacts of Turpan and Khotan. Currently, fragments of the murals from the Kuche grottoes are scattered among various countries, including Russia, Germany, and Korea. With the publication of this catalog, it seems like an opportune time to publish a comprehensive catalog on the murals of the Kuche region, which represent a compelling mixture of East-West culture that reflects the overall characteristics of the region. A catalog that includes both the remaining murals of the Kizil grottoes and the fragments from different parts of the world could greatly enhance our understanding of the murals' original state. Such a book would hopefully include a more detailed and interdisciplinary discussion of the artifacts and murals, including scientific analyses of the pigments and other materials from the perspective of conservation science. With the ongoing rapid development in western China, the grotto murals are facing a serious crisis related to climate change and overcrowding in the oasis city of Xinjiang. To overcome this challenge, the cultural communities of China and other countries that possess advanced technology for conservation and restoration must begin working together to protect and restore the murals of the Silk Road grottoes. Moreover, centers for conservation science should be established to foster human resources and collect information. Compiling the data of Russian expeditions related to the grottoes of Kuche (among the results of Western archaeological surveys of the Silk Road in the early twentieth century), Kuche Art Relics Collected in Russia represents an important contribution to research on Kuche's Buddhist art and the Silk Road, which will only be enhanced by a future volume introducing the mural fragments from Germany. As the new authoritative source for academic research on the artworks and artifacts of the Kuche region, the book also lays the groundwork for new directions for future studies on the Silk Road. Finally, the book is also quite significant for employing a new editing system that improves its academic clarity and convenience. In conclusion, Dr. Kira Samosyuk, who planned the publication, deserves tremendous praise for taking the research of Silk Road art to new heights.
