"Jonkyongkak" which King, Sungjong of Yi dynasty established within Sungkyunkwan in 1475 is regarded as the first university library in Korea. On the basis of modern librarianship, however, it is desirable to recognize the fact that Keijo Imperial University Library is really the first university library in Korea. In this thesis, an attempt to study the Korean university libraries under the period of Japanese control is provided. Keijo Imperial University Library is the key institution in this study. This study will focus to review the following facts: 1) the historical background of Keijo. Imperial University Library; 2) the organization and staffing pattern, and budget of this library; 3) the acquisition policy and basic collection development plan of this library; 4) the library and other services of this library including readers services; 5) the relationship with other private college libraries; and 6) the impact of this library on the present Seoul National University Library. The followings are the outlined conclusions: 1. Japanese Government had established Keijo Imperial University Library in order to perform the colonial education policy of Korean peninsula. Furthermore, it was one of the import supporting agencies for the research activities which were necessary for Japan to govern the Southeast Asia including Korean Peninsula 2. The organization and staffing size and pattern of this library are much below to those of modern university libraries. They are somewhat below to the level which is necessary to perform the minimum basic library functions. 3. The priorities of book collection of this library are 1) humanities and social sciences especially, materials on Law are much emphasized; 2) pure sciences and 3) technologies and agriculture. Therefore, the quantity of the materials on the field of technology and agriculture is very small. 4. The acquisition policies of this library are deeply influenced by the Japanese Government's colonial policy of Korean peninsula and her aggressive policy of Chinese Continent. 5. The major contribution of this library to the present Seoul National University Library is the transfer of 550,000 volumes of books and library building, but this building is now removed according to the transfer of Seoul National University Campus. 6. The staffing pattern of this library was, however, much ahead of that times. Especially, the facts that professional librarians were eligible to be appointed as the director of this library, and they had the faculty membership including faculty rank should be highly appreciated.

In this paper, we propose the development of an eBook Service System based on VOD Broadcasting Contents(eBSS-VOD) which protects the illegal copy through the effective DRM strategy. Here, eBSS-VOD is composed of three sub-systems - eBook server management system, ePub Builder, and eBook App - according to the functional points of view. The eBook server management system operates to manage the eBooks, the encription keys, the VOD contents, the membership and the history of users' viewing log. The ePub Builder assists to produce eBooks by DRM strategy. The eBook App provides users with the utility services of VOD viewing and eBook purchase processing. The proposed eBSS-VOD, differently from the current eBook systems, helps to increase the users' interests in reading books and to motivate the users' purchasing needs and it also makes new distribution channel for eBooks based on VOD broadcasting contents through smart applications. We provides the differentiated eBook builder which are based on ePub3.0 and DRM strategy. Through empirical survey results on users' interests and purchase intention for eBooks, we show that the proposed eBSS-VOD has the comparative effects compared to the current systems.

This study aims to identify unique small group norms and their influence on the process of constructing a scientific model. We developed instructional materials for the construction of a model of blood flow in the heart and conducted research on eighth-grade students from one middle school. We randomly selected 10 small groups, and videotaped and recorded their dialogues and behaviors. The data was categorized according to the types of interaction and then analyzed to investigate the characteristics of group norms and models in one or two representative groups for each type. The results show that the types of interaction, the quality of the group models, and the group norms were different in each group. Even though one teacher guided students through the same task in the inquiry context, each group revealed different patterns of discourse and behavior, which were based on norms of cognitive responsibility, the need for justification, participation, and membership. With the exception of one group, there was little cognitive responsibility and justification for students' opinions. Ultimately, these norms influenced the model construction of small groups. A group that forms norms to encourage the active participation and justify members' opinions with cognitive responsibility was encouraged to do inferential thinking and construct a group model close to the target model. This study has instructional implications for the establishment of a classroom environment that facilitates learning through small group activities.

The development of hot social networking services, including the Internet, has transformed rental car services into IT-based car-sharing services. The car-sharing service is a service that allows people to rent cars online without having to face-to-face. It has become the preffered service among young people who are accustomed to drinking and eating alone. Users can use their smartphones to book their types of cars and hours of rent, and then go to a nearby designated parking lot to use their reserved cars. You can open a designated car door with a smart phone and drive. It is a very convenient service to pay for the distance you drive. However, the car-sharing service already in use in business has the following problems: underage who do not have a driver's license may drive a car borrowed by an acquaintance, the status of a license registered at the time of join membership with a car-sharing company may change to a suspension or cancellation of a license while renting and driving, or even a drunk person may rent a car and drive. In this paper, the method to solve these problems has been studied and proposed. The proposed method is to reduce the cost of investment by a car-sharing service provider and to minimize user inconvenience. And, it was compared and analyzed with the existing method. For the method to be used efficiently, the active operation of the car-sharing company and the government's policies will have to be supported.

Joseph Mallord William Turner (1775-1851) has been widely regarded as the most original and brilliant English landscape painter in the 19th century. Admitted to the Royal Academy Schools in 1789, Turner was a precocious artist and gained the full membership of the prestigious Royal Academy in 1802 at the age of 27. Already in the 1800s he was recognised as a pioneer in taking a new and revolutionary approach to the art of landscape painting. Among his early works made in this period, The Shipwreck, painted in 1805, epitomizes the sense of sublime Romanticism in terms of its dramatic subject-matter and the masterly display of technical innovations. Of course, the subject of shipwreck has a long standing history. Ever since human beings first began seafaring, they have been fascinated as much as haunted by shipwrecks. For maritime societies, such as England, shipwreck has been the source of endless nightmares, representing a constant threat not only to individual sailors but also to the nation as a whole. Unsurprisingly, therefore, shipwreck is one of the most popular motifs in art and literature, particularly during the 18th and 19th centuries. Yet accounts, images and metaphors of shipwreck have taken diverse forms and served different purposes, varying significantly across time and between authors. As such, Turner's painting registers a panoply of diverse but interconnected contemporary discourses. First of all, since shipwreck was an everyday occurrence in this period, it is more than likely that Turner's painting depicted the actual sinking in 1805 of the East India Company's ship 'The Earl of Abergavenny' off the coast of Weymouth. 263 souls were lost and the news of the wreck made headlines in major English newspapers at the time. Turner's painting may well have been his visual response to this tragedy, eyewitness accounts of which were given in great quantity in every contemporary newspaper. But the painting is not a documentary visual record of the incident as Turner was not present at the site and newspaper reports were not detailed enough for him to pictorially reconstruct the entire scene. Rather, Turner's painting is indebted to the iconographical tradition of depicting tempest and shipwreck, bearing a strong visual resemblance to some 17th-century Dutch marine paintings with which he was familiar through gallery visits and engravings. Lastly, Turner's Shipwreck is to be located in the contexts of burgeoning contemporary travel literature, especially shipwreck narratives. The late 18th and early 19th century saw a drastic increase in the publication of shipwreck narratives and Turner's painting was inspired by the re-publication in 1804 of William Falconer's enormously successful epic poem of the same title. Thus, in the final analysis, Turner's painting is a splendid signifier leading the beholder to the heart of Romantic abyss conjoing nightmarish everyday experience, high art, and popular literature.

The cascade face detector learned by Adaboost algorithm, which was proposed by Viola and Jones, is state of the art face detector due to its great speed and accuracy. In spite of its great performance, it still suffers from false alarms, and more computation is required to reduce them. In this paper, we want to reduce false alarms with less computation using facial color. Using facial color information, proposed face detection model scans sub-window efficiently and adapts a fast face/non-face classifier at the first stage of cascade face detector. This makes face detection faster and reduces false alarms. For facial color filtering, we define a facial color membership function, and facial color filtering image is obtained using that. An integral image is calculated from facial color filtering image. Using this integral image, its density of subwindow could be obtained very fast. The proposed scanning method skips over sub-windows that do not contain possible faces based on this density. And the face/non-face classifier at the first stage of cascade detector rejects a non-face quickly. By experiment, we show that the proposed face detection model reduces false alarms and is faster than the original cascade face detector.

Wooded areas that are a part of school campuses are one type of urban forest. Most schools located in an urban environment make an excellent setting for a forest in terms of location and area. These kinds of wooded spaces also make the city greener and healthier. As a place where students spend a great deal of time, schools can also be a venue for environmental education. The creation of wooded areas in schools currently has focused on the end result only; by ignoring student needs and participation, these areas have not had a significant influence on student environmental education. Previous studies based on questionnaire survey are significant in that they have quantified subjective qualitative data via Likert Scale. There has been, however, a problem in quantifying the more ambiguous subjective data. Therefore, this paper has attempted to investigate those factors that have an influence on student satisfaction with the wooded areas of their school campus using Fuzzy Theory with elementary school students in Gyeongsangbuk-do. A change was observed in terms of the ranking of arithmetic mean values of 'school peculiarity' and 'emotion evolution' and center of gravity, which has adopted Fuzzy Theory, proving that Fuzzy Theory could rationally objectify qualitative data such as human thoughts. In terms of the influential factors on the satisfaction with school forests(regression coefficient), 'school uniqueness(0.159)' was the highest, followed by 'many trees(0.142),' 'importance of nature(0.136)' and 'emotion evolution(0.130).' This paper may therefore be useful as basic data for objective questionnaire surveys and the development of school forests.

The purpose of the water distribution system is gradually changing to increase the flexibility for responding to various abnormal situations. In addition, it is essential to improve resilience through preparing emergency plans against water supply failure. The most efficient way is emergency interconnections which supply water from interconnected adjacent blocks. To operate successful interconnections, it is essential to evaluate the supply performance in spatial and temporal aspects. The spatial and temporal aspects are dominated by its interconnected pipes and interconnected reservoirs respectively. In this study, an emergency interconnection scenario where problem occurred in reservoir 1 at 0:00hr in A city, Korea. An Advanced-Pressure Driven Analysis model was used to simulate the volume and inflow volume of the interconnected reservoirs. Based on the hydraulic analysis results, a multi-dimensional evaluation of the supply performance was conducted by applying possible water supply range indicator (PWSRI) and possible water supply temporal indicator (PWSTI) which are based on fuzzy membership functions. As a result, it was possible to evaluate the supply performance on the sides of consumers in spatio-temporal aspects and to review whether established plans mitigate the damage as intended. It is expected to be used for decision making on structural and non-structural emergency plan to improve the performance of an emergency interconnection.

The research status of endangered amphibians in Korea was mainly studied the life-cycle and distribution status of species from the 1980s to the early 2000s. Although a relatively diverse range of studies have been conducted on mackerels, studies on habitat prediction, analysis, change and management are insufficient. WEB, which provides biota information using location information in Korea, is a site operated by the National Bio Resource Center under the Ministry of Environment, but there is no information on endangered species and general species information has also been found to be very scantily. For this research, we secured a database of location information of Narrow-mouth frog, an endangered species, by combining literature and field research, and established a system by applying new technologies and open-based platform technologies that can be easily accessed by non-technical personnel of IT among IT technologies. The system was divided into administrator functions and user functions to prevent indiscriminate sharing of information through authentication procedures through user membership of users. The established system was authorized to show the distance between the current location and the location of the Narrow-mouth frog. Considering the ecological characteristics of the Narrow-mouth frog, which is an endangered species, a radius of 500m was marked to determine the habitat range. The system is expected to be applied to the legal system to change existing protected areas, etc. and to select new ones. It is estimated that practical reduction measures can be derived by utilizing the development plan for reviewing the natural environment. In addition, the deployed system has the advantage of being able to apply to a wide variety of endangered species by modifying the information entered.

Purpose - A business ecosystem refers to mutually dependent systems interconnected by a loose foundation of various ecosystem members such as customers, suppliers, partners, and other stakeholders. The ecosystem-based strategy attempts to achieve competitive advantage for firms by enriching a business ecosystem or building a sustainable business ecosystem through the collaboration and co-evolution of its members. A sustainable business ecosystem is a source of competitiveness for firms anda manageable resource for gaining a competitive advantage. Customers represent the core membership of the business ecosystem and play a pivotal role in building a sustainable business ecosystem. This study examines the effects of customer participation on economic and social value in the business ecosystem and suggests a course of action for building a sustainable business ecosystem. Research design, data, and methodology - Two business cases of South Korea are selected from two different business types: business-to-business (B2B) and business-to-customer (B2C) firms. Business ecosystems for B2B and B2C firms reflect contrasting characteristics. Data was collected from in-depth interviews with four representatives of four firms. Results - The study suggested seven propositions for the relationships between customer participation and a sustainable business ecosystem through multiple case studies based on in-depth interviews. The results reveal the following four strategic actions for building sustainable business ecosystems based on the suggested propositions: alignment, systemization, socialization, and co-evolution. Alignment refers to achieving a harmonic balance or virtuous circle among the firm's mission, investment, and value creation. Systemization refers to building and implementing management and infrastructure systems rooted in the corporate culture. Socialization of customers in the business ecosystem reinforces the harmony or virtuous cycle. Finally, co-evolution is associated with the relationship between firms and customers as buyer firms in a restricted business ecosystem. Conclusions - This study considers multiple cases for the execution of a sustainable business ecosystem in collaboration with customers and suggests seven propositions and four strategic actions. The results are based on qualitative data from interviews with business associates from two firms in an open business ecosystem and two firms in a restricted business ecosystem, both in South Korea. Our research results regarding two contrasting business ecosystems shed light on business issues and policy making in Asian business environments, which are in the transition stages from a traditional conglomerate-driven to an inclusive growth-driven economy. The business ecosystem itself should be considered a manageable resource for firms' competitive positions in the market. A customer is a member of the business ecosystem and should thus be viewed not only as a purchasing entity and an object of relationship management but also as a co-creator of value. Therefore, firms should collaborate with customers to build sustainable business ecosystems. For this, firms must create social value, which cannot be created by customers alone, within the business ecosystem. Then, customers participate in a business ecosystem and build it to be favorable to them. Implications for academics and practitioners were suggested.
