  • Because we can usually get many information through analyzing trajectories of moving objects on spatial networks, efficient trajectory index structures are required to achieve good retrieval performance on their trajectories. However, there has been little research on trajectory index structures for spatial networks such as FNR-tree and MON-tree. Also, because FNR-tree and MON-tree store the segment unit of moving objects, they can't support the trajectory of whole moving objects. In this paper, we propose an efficient trajectory index structures based on signatures on a spatial network, named SigMO-Tree. For this, we divide moving object data into spatial and temporal attributes, and design an index structure which supports not only range query but trajectory query by preserving the whole trajectory of moving objects. In addition, we divide user queries into trajectory query based on spatio-temporal area and similar-tralectory query, and propose query processing algorithms to support them. The algorithm uses a signature file in order to retrieve candidate trajectories efficiently Finally, we show from our performance analysis that our trajectory index structure outperforms the existing index structures like FNR-Tree and MON-Tree.

  • In recent years, countries such as USA, United Kingdom and Australia have begun to implement national policies in order to systematically manage and share research data produced through publicly funded research. However, Korea as of yet does not have a coordinated research data policy. The lack of infrastructure that supports the sharing and preserving research data results in the poor management and loss of valuable data produced from significant national R&D investments. The need for research data collection, management and sharing goes beyond the outcome assessment of national research: it facilitates the diffusion of research impact and economic development. There is a growing recognition that data sharing is an essential element of research ethics. This research investigates the relevant research data policies and methods of governance at the national level using a case study analysis. United Kingdom was selected as a case study target as it shows a wide variety of policy examples and instruments. In particular, this research focuses on the UK's national legal framework for research data sharing, analyzes the RCUK (Research Councils UK)'s data policies, activities at the seven research councils under RCUK as well as several supporting institutions. Based on the analyses, this research offers a national roadmap for better managing and sharing of research data in Korea.

  • Mengzi's biological analogies of man's moral tendency need to be analyzed in order to understand his ethical perspective because he uses lots of analogies to advocate his own moral naturalism. The biological analogies he uses are composed of human body, plant's seeds and sprouts. First, Mengzi thinks that human beings have inborn moral nature as if our bodies are given and plants can be grown from their seeds. His ethical approach to define morality in terms of natural properties such as the Four Sprouts(四端) causes a philosophical debate with Gaozi who thinks that morality cannot be described by natural property. Second, we have a moral preference as if we have a physical desire. This kind of moral sentimentalism emphasizing the preference is continued to Jeong Yakyong's ethical theory that nature is a preference(性嗜好說). Third, if we examine our preference and desire, then we can find that the moral preference is more valuable than the physical desire. Fourth, the biological analogies accepts monism that mind and body are composed of material force(氣). For this reason, the innate moral tendency is manifested on body such as a facial expression, a visceral reaction, and affect. Finally, Mengzi's theory of Four Sprouts causes two different interpretation. One is Zhuxi's interpretation that Duan端 is the visible end(緖) of a thread out of pack, the other is Jeong Yakyong's interpretation that Duan端 is a starting point(始) to cultivate virtues. While Zhuxi considers the Four Sprouts as a clue to find virtues in one's mind, Jeong Yakyong believes that we can cultivate our virtues by preserving the Four Sprouts.

  • In order to improve a trip pattern in Mt. Halla climbing only to a summit, two trip programs with nature interpretation have been developed using the geomorphic characteristics of Mt. Halla which are distinct from those of mountains in the Korean peninsula. It also aims to help conservation of natural environment of Mt. Halla and to enhance the visitor satisfaction in Mt. Halla. The subalpine trip program is carried out on a 1.5 km-long trail between Wissaeoreum Hut and Janggumokoreum. Program participants are able to learn expertise about, and understand vulnerability of, a subalpine ecosystem, Consequently, the program can obtain an educational attainment getting them to recognize the necessity of preserving the subalpine zone of Mt. Halla as an important natural resource. The mountain river trip program is performed on a 1.5 km-long reach of Byeongmun River between Gwaneumsa trailhead and a gorge upstream of Gurin Cave. The program is capable of exhibiting effectively the river characteristics of Jeju Island using the geomorphic and hydrologic properties of Byeongmun River which differ from those of rivers in the Korean peninsula. Since the subalpine grassland and ephemeral stream of Mt. Halla are the visiting places which are rarely experienced in the Korean peninsula, the program participants can understand the regionality of Jeju Island as well as Mt. Halla through trip activities.

  • This paper examines the origin of the current Nigerian Yoruba artistic and cultural tradition through ancient artifacts and creation myths centered on $Il{\acute{e}}-If{\acute{e}}$ (or $If{\acute{e}}$) located in the southwestern part of Nigeria and recognition of cultural relativity. In the oral tradition, kingdoms of Ijebu, Oyo, and Benin all have their origins in the ancient city of $Il{\acute{e}}-If{\acute{e}}$, the cradle of Yoruba culture. Their founders were sons of Oduduwa, the god of Yoruba. In this way, kingdoms built around $Il{\acute{e}}-Ife$ were closely connected with culture, religion, and society. In order to understand the Yoruba culture, research on $Il{\acute{e}}-Ife$, the source of their artistic and cultural traditions, is very important. The Yoruba are deeply rooted in $Il{\acute{e}}-Ife$. They have been steadily preserving their artistry since the beginning. They have been using it in their lives to this day for centuries. Their evidences are mythology and Ifa divination system. They are cultural heritages that represent the art of Yoruba and the spiritual culture. Ifa devination system is one of Yoruba traditions associated with Yoruba gods 'Eshu' and 'Ifa'. It has been conducted among the Yoruba until now. If the culture and civilization of Africa, including these Yoruba traditional customs, are deemed illogical and superstitious, it would mislead their efforts to preserve the origin in its original form. If so, one should understand the relativity of other cultures and civilizations and the need for diversity and flexibility of value standards to judge their cultures and civilizations.

  • This essay introduces the basic method and program required to meet some necessary conditions of building university archives. By the phrase 'method and program', I intend the effective means of regularly but circumstantially controling the ways to the archival purposes proper which can be defined as the keeping of evidences and the broadening of information pool in terms of the evidential and informational natures or values of records. My starting point is about the matters of overcoming a standard method of induction which has long prescribed much passive procedures in the archival work. Considering the differences in the records and archives management-practices between West and Korea, I tentatively try to add some active elements to the archival work among which the collection for the expanding evidences and informations may firstly emphasized. While this collecting activity normally depends on the existing 'collections' and 'manuscripts', I cannot exclude the possibility of collections the materials, being likely to be registered in any poor or insufficient record groups. In the similar context, this kind of activity may and must be expanded beyond the university boundaries so at to arrange the cornerstones of archive-based local studies in the various disciplines. Here I premise another role of university archives, the role as 'science archives'. These archives within university archives seem likely to function in likewise the special collections within Western university libraries. What I mean here, however, is the archival groups purposedly gathered or acquisited according to more detail and narrower plan in order to meet the various demands from the different disciplines for the primary sources. The archival procedures from this revised method and program may, I hope, satisfy some of the preconditions of building university archives before the archives will actually function as a sub-institution of an university preserving legal, administrative and financial evidences, thus keeping identity and continuity of the university on the one hand, and as a local information center of supplying the archival contents on effectual demand from the field of local studies on the other. Finally, I conclude with a suggestion concerning the cooperation of all the parties of archival works. Proposing the 'Regional Research Center Program' in the field of technology and engineering as a model for the cooperation, I suggest that universities, private/public organizations, and central and local governments may work together for surveying the scattered ancient and modern documents as well as for building archives under the matching fund.

  • After inspecting ground surface or excavating cultural heritage site, the government can take measures for the preservation of buried cultural heritage based on the related law. It means that the provisions complement the limitation of current cultural heritage management system by extending the scope of cultural heritage to be preserved. But we neither have set any matters about implementing the measures for preservation of the buried cultural heritage, nor manage the heritage and its surroundings after implementing the measures. Due to these insufficiency of the law, there arise several problems in the field. For example, the measures for preservation are not complete, or preserved cultural heritage is damaged due to inappropriate management. We have to resolve the problems in order to accomplish the original purpose of taking measures for preservation of the heritage. First, it is necessary to make sure of the legal status of preserved buried cultural heritage, to establish the standards to decide whether to preserve it or not. We need to have regulations by law or internal rule on the daily management, who should manage it, what and how the manager should manage. It is also important for local residents to take an active part in preserving and utilizing the cultural heritage as the owner. Through building up the foundation mentioned above, the meaning and value of preserved buried cultural heritage can be expanded widely.

  • This study examines Korea's revitalization policy on the ancient capital cities, which has been set out for preserving and improving living quality of the local communities. Since it was established, the policy has faced with constant challenges such as the lack of funding for preservation and revitalization of local communities. This study aims at providing a set of recommendation on the problems on the policy. In order for the study, it takes objective and empirical analysis on the problems of the policy by executing survey on the satisfaction level of the stakeholders and policy-makers on the present policy. The survey has displayed that the government needs to 1. subsidize more budget, 2. set out a policy to reduce the inconvenience of local communities 3. establish a supportive program to help the present promotion policy. In addition, the survey analysis has proved that the elements of revitalization policy affect to the increase of satisfaction. It concludes with a set of recommendation, 1. to secure sufficient budget to implement the policy; 2. to reduce a restriction of individual rights; 3. to promote the supporting program of local community; 4. to establish governance system with officers, experts, residents, and research institutes.

  • Industrial heritage resources produced by industrial activities have historical and conservative values and value as cultural properties as they serve as a medium connecting the past, present, and future. In other words, Industrial heritage resources should be used, managed, and preserved simultaneously as important records and evidence for the future. Metadata is well known as a necessary and important factor for the use, management, and preservation of information resources. In particular, in order to describe various industrial heritage resources that have historical, cultural, and conservative values, metadata elements from various perspectives are needed to relate to the story, type etc. of data. Therefore, this study attempted to design metadata elements that can comprehensively describe different types of industrial heritage resources. And we designed metadata that suited for the purpose of using, managing, and preserving industrial heritage resources, through mapping and combination between industrial heritage-related metadata. As a result, metadata was grouped into five types(administrative, descriptive, preservation, technical, use) and prepared into a total of 25 higher & 86 lower elements.

  • This study was conducted to prepare basic data by analyzing the biological values and environmental factors of algific talus slope in order to respond to climate change due to the greenhouse effect, and to establish plans for forest biodiversity preserving and managing. Meteorological information was measured and the flora of vascular plants were investigated for six algific talus slope by seasonally from 2020 to 2021. As a result of the investigation, the temperature of all 6 algific talus slope was lower than that of the area where the algific talus slope was located in summer, and flora was 101 families, 350 genera, 621 species, 18 subspecies, 57 variants, 7 varieties, 703 taxa. In sum, it is judged that the algific talus slope has sufficient reasons and value to be preserved because it has excellent micrometeorological value from the cold wind blowing in summer and phytogeographical value in which various plants live in a small area. However, in spite of such an important area, the management of algific talus slope is insufficient, and the algific talus slope is damaged or the ecosystem of the algific talus slope is disturbed. Therefore, it is necessary to establish a systematic conservation and management plan by designating algific talus slope as a forest genetic resource reserve and OECM.
