The objective of our research was an international comparison focusing on studies conducted on parks and green spaces undertaken in Japan and Korea. We also aim to clarify the similarities and differences between the two countries and consider the key features of the researches on the field of landscape architecture. We compared the recent trends of Japanese institute with Korean observed in the theme of research papers adopt title of them. The research period spanned approximately twenty years, from 1980 to 2003. We employed the Table of Contents information search system to research academic journal articles and to select the journals that included articles with the key words [park(s)] or [green space(s)] in their title. We chronologically arranged the journals for each country, based on the total number of journals and classification categories. We then conducted a comparative examination among the two countries. We also contributed information on the circumstances behind the formulation or amendment of some policies and laws and we checked the results against the research trend. Among the selected journals, the number of papers was the highest by the Institute of Landscape Architecture. But the reason for increase of the number of papers on green spaces in Japanese journals was not published by the Institute of Landscape Architecture but by the City Planning Institute and the Architecture Institute. In Japan, the papers on parks categorized under historical study were the highest among all categories. On the other hand, in Korean journals, papers on parks categorized under historical study were few. A similar trend was recognized in papers on green spaces. Every society is concerned with the study of function and effect. However, some exact differences have been observed by category classification. In Japan, the percentage of function and effect papers on parks was less than those on green spaces. In Korea, both percentages for these groups were high. The category of system and policy accounted for $17\%$ of the papers on green spaces in Korea. This result was higher than the number of papers on green spaces and parks in Japan and parks in Korea. Recently, the number of papers focusing on large-scale green space system has decreased in Japan. The trend in the study of parks and green spaces on a regional scale or at an individual level will be closely monitored. Systems and modeling studies have been focusing in Korea. The understanding between the administration and the citizens was peculiar to each country.

In this paper, we examine the forecasting KOSPI 200 realized volatility by volatility measurements. The empirical investigation for KOSPI 200 daily returns is done during the period from 3 January 2003 to 29 June 2007. Since Korea Exchange(KRX) will launch VKOSPI futures contract in 2010, forecasting VKOSPI can be an important issue. So we analyze which volatility measurements forecast VKOSPI better. To test this hypothesis, we use 5-minute interval returns to measure realized volatilities. Also, we propose a new methodology that reflects the synchronized bidding and simultaneously takes it account the difference between overnight volatility and intra-daily volatility. The t-test and F-test show that our new realized volatility is not only different from the realized volatility by a conventional method at less than 0.01% significance level, also more stable in summary statistics. We use the correlation analysis, regression analysis, cross validation test to investigate the forecast performance. The empirical result shows that the realized volatility we propose is better than other volatilities, including historical volatility, implied volatility, and convention realized volatility, for forecasting VKOSPI. Also, the regression analysis on the predictive abilities for realized volatility, which is measured by our new methodology and conventional one, shows that VKOSPI is an efficient estimator compared to historical volatility and CRR implied volatility.

The purpose of this study is to enhance the cultural heritage value of the Juk-Bang-Ryeum (Bamboo Weir) and prove the originality through the review of historical literature. The main industry of Korean was agriculture and fishery from ancient. In the ancient, fishery instruments are not enough due to the lack of fishing technology. The Juk-Bang-Ryeum was considered as important national resources and asset. It give us many implications about the wisdom of our ancestors because of it's scientific principle of the structure. It is surely a cultural heritage to preserve in the future because it is considered as important community asset as well as more natural and environment oriented fishing method. In the literature, the origin of 'Juk-Bang-Ryeum' can be found as 'Eo-Ryang' or 'Bang-Ryeum'. The records on this terminology go back to the Corea Dynasty, but their documentary records are rare, and most of them are records of the Chosun Dynasty. In this study, we surveyed mainly the literature records about the southern coast region in the period of Chosun Dynasty. This study contributes for preserving the cultural assets of our ancestors who pursued eco-friendly fishery method, and it is also of great significance to produce objective data based on records for the registration of the World Record Heritage.

The collection and transfer of records is a very basic stage in the whole process of records and archives management. However they are regarded as an non-professional art of work in records management that are performed easily by everyone. Therefore they have been treated not properly in the scholarly discussion of archival sciences in Korea. The collection and transfer of records play an active role in the making of effective administrative system, in accumulating and sharing the knowledge and informations of political, economical, social and cultural values. On the basis of proper collection and transfer of records our democracy can operate regularly and our daily experiences can be preserved as historical resources. For the optimal-functioned collection and transfer of public records the archivists for this task must have a comprehensive understanding of whole process of records management and possess suitable professional skills. Moreover there are many sorts of preliminary works needed for this task, as follows: an accurate defining of administrative organizations and their tasks, thorough understanding of records management institutions on their own competence and ability, and the establishment of technical standards for their tasks. Additionally the archivists are able not only to consider the present informational and evidential values of the records, but also the historical values. It can be said that the collection and transfer of records is a "synthesis of records management skills" exerted by an archivist. According to the newly established law of public records management, the collection and transfer of public records must be registered at first electronically. Through this procedure the whole contents of produced and transmitted records, which are to be transferred, can be reported in detail. By means of this report the archival institutions and the archivists can trace back the each items of records(archives) and the result of their arrangement to identify a certain object. There are also new storage strategies employed to increase the whole sum of stored informations, i. e. records and archives, in spite of reducing the storage costs. It will be achieved by differentiations of the preservation methods for each sorts of records by the criteria of storage-period, -place, and -method. Many supplementary methods are also prepared to help the collection of important records(archives) in a complete structure and form. To let this new concept and system of collection and transfer of records operate properly, a number of professional archivists should be posted in the needed places throughout the whole administrative body. Their training must be also updated for the newly defined task of collection and transfer of records.

The study was done to analyze the records of planting time of Gwangneung needle firs referring to the historical literatures, the Annals of Joseon Dynasty(朝鮮王朝實錄), Seungjeongwonilgi(承政院日記: Journal of the Royal Secretariat). Bibyeonsadeungnok(備邊司謄錄: Records of the Bibyeonsa Defense Council, a government agency during the Joseon Dynasty), Ilseongnok(日省錄: Journal on Dynasty affairs of the kings in the 36th year of Youngjo to 1910) to lay the historical ground for needle firs in Gwangneung. The following results were derived from previous research, Report on Gwangneung Forest Ecosystem, and overlaid fir tree rings. The research findings are as follow. First, since the system of making the grave is the most conservative system, the planting during the Gwangneung construction would have been preceded by precedent. Second, the problem of cutting the tree in the late Joseon Dynasty became serious. It is published the Law of Muo In the 22nd year of Jeongjo, and then planted trees regularly in spring and autumn. Third, the Law of Muo was preserved for 31 years during the reign of King Gojong, and the type of specific tree, the number of trees, from the 22nd year until the 25th year of King Gojong, four years of fir trees were planted in Gwangneung, and Gwangneung was the only place where korean pine trees were planted. Fourth, it was possible to identify the age of the tree through fallen fir tree rings, and the period of planting fir trees growing in the existing mausoleum is judged to be the equivalent year of King Gojong's reign from the 10th year of King Cheoljong's reign.

The purpose of this study is to trace the formation process of "parallel provenance" concept in the context of Australia's aboriginal community archives development and draw its implications for contemporary rebuilding of domestic "past affairs-related committee archives". Focused on historical development of aboriginal community archives in Australia, this writing divides its development into three periods: colonial archives, post-colonial archives, and contemporary archives and investigates each period's distinct features in managing and building of aboriginal community archives. First of all, for colonial archives, it pays attention to Australia's archival tradition, which focused on current record-keeping and then development of multiple provenance resulted from this tradition. Second, for post-colonial archives, it examines the appearance of aboriginal people as the subject of documentation category and name indexing on them. Finally, for contemporary archives, it analyzes current activities of Australia's academic world of archival science for overcoming "the otherness" of aboriginal people through conceptualization of "parallel provenance". Conclusively, through current meaning of parallel provenance, this study draws implications for democratic contemporary rebuilding of domestic past affairs-related committee archives, in which historical victims become the subject of archives.

The purpose of this study is to analyze historical records of what the trees had been planted like by establishment and management of the Royal Tombs of the Joseon Dynasty so that it could be utilized for historical records to manage the trees in the Royal Tombs. The research method was to analyze the related keywords for 40 trees out of 42 trees in the Royal Tombs of the Joseon Dynasty reffering to "The Annals of the Joseon Dynasty(朝鮮王朝實錄)," and "Neungji(陵誌)". There are two types of planting called Jeongsik(定植) Bosik(補植) in the Royal Tombs. Jeongsik(定植) is a planting method by Salleungdogam(山陵都監), the office in charge of construction of the royal tomb when they were building the royal tomb. Every tree additionally planted after building up the royal tomb was called Bosik(補植). The types of tree planting the composition and management of the royal tombs of Joseon are as follows. First, the first planting for landscaping was carried out during the process of building the province. Second, after the formation of Shanung, all the plants were planted by Wangmyung as additional plants. Third, due to the deforestation in the late Joseon period, additional plants were planted in the fertile plains. Fourth, trees were damaged due to natural disasters, and trees were planted together with the construction of the botanical gardens. Fifth, in the 22nd year of King Jeongjo, all the royal families' graves were regularly planted. This study aims to investigate the history of forest landscape management for the restoration of the royal tombs of Joseon.

This paper deals with three issues related to influx and change of the Confucian Shrine Ritual Music. First, the musical instrument of the Akhakgwebeom-wooden frame-form used in the current Confucian Shrine Ritual Music is not a form that came in when the Daesung-Aak of the Song Dynasty was introduced in 1116, but it is a Yuan Dynasty form brought from the Ming Dynasty, in the 19th year of King Kongmin. In the Song Dynasty of the Goryeo Yejong era, when Daesung-Aak came in, there was not yet 'Baeso', a musical instrument of the Akhakgwebeom form, which first appeared in the Yuan Dynasty. A new musical instrument named 'Baeso' appears with the 'So' in the later period of King Gongmin, and it is very likely that this 'Baeso' is the musical instrument of the present Akhakgwebeom form. Second, although the form of the 'So' in the Joseon Dynasty recorded in the Akhakgwebeom was followed by the Chinese one, but the pitch and arrangement are the one of the pitch of '12 Yul and 4 Cheongseong' and the arrangement of the pitch from left to right. Third, in the 1930s, the whole form was the same as that of the Akhakgwebeom, but there existed two types, which several pipes stick together or pipes fall apart. But since then, as seen in the musical instrument located at Kyungpook National University Museum and in instruments currently used in Confucian Shrine Ritual Music, only musical instruments exist which pipes fall apart. It is unclear for what reason and to what extent the 'So' were so transformed, but it would be appropriate to re-establish the form of the 'So' in the musical and historical point of view.

Identifying the available water resources amount is an essential process in establishing a sustainable water resources management plan. Dam facility is a major infrastructure storing and supplying water during the dry season, and the water supply yield of the dam varies depending on dam inflow conditions or operation rule. In South Korea, water supply yield of dam is calculated by reservoir simulation based on observed historical dam inflow data. However, the water supply capacity of a dam can be underestimated or overestimated depending on the existence of historical drought events during the simulation period. In this study, probabilistic inflow data was generated and used to estimate the appropriate range of the water supply yield of hydropower dams. That is, a method for estimating the probabilistic dam inflow that fluctuates according to climatic and socio-economic conditions and the range of water supply yield for hydropower dams was presented, and applied to hydropower dams located in the Han river in South Korea. It is expected that the understanding water supply yield of the hydropower dams will become more important to respond to climate change in the future, and this study will contribute to national water resources management planning by providing potential range of water supply yield of hydropower dams.

While the Forward Freight Agreement (FFA) has emerged as an effective hedging tool since early 1990, the basis risk and cash flow distortions have been addressed as obstacles to the active use of FFAs. This research analyses the basis risk of FFAs and provides a feasible suggestion to reduce it. Basis risk is divided into timing basis, route basis, size basis, and low liquidity basis. The timing basis is defined as the difference between the physical hire, fixed on the specific contract date and the FFA settlement price, calculated by averaging spot rates for a certain period. Timing basis is considered the worst in eroding the effectiveness of FFAs. This paper suggests a change of hire payment criterion from contract date to 15-day moving average, as a means of mitigating the basis risk, and analyzed the effectiveness through historical simulation. The result revealed that the change is effective in mitigating the timing basis. This study delivers a meaningful implication to shipping practice in that the change of hire payment criterion mitigates the basis risk and eventually activates the use of FFAs in the future.
