  • Information system(IS) development projects are mostly unique in terms of the characteristics of projects such as project requirements, customers, project members, and development environment. Therefore, it is very hara by nature, to manage the development process systematically. In addition the long-term enlarged scale projects with more complexity and specificity required have brought in much more risk factors than before. The paper recognized risk factors in IS development projects and measured the importance of those risk factors using the AHP(Analytical Hierarchy Process) method. The results can be used in the risk management of IS development projects.

  • As interest in beauty has increased, various studies have been conducted, and related companies have considered the anthropometric data handled between humans and interfaces as an important factor. However, owing to the nature of 3D human body scanners used to extract anthropometric data, it is difficult to accurately analyze a user's body shape until a service is provided because the user only scans and extracts data. To solve this problem, the body shape of several users was analyzed, and the collected anthropometric data were obtained using a 3D human body scanner. After processing the extracted data and the anthropometric data, a custom deep learning model was designed, the designed model was learned, and the user's body shape information was predicted to provide a service suitable for the body shape. Through this approach, it is expected that the user's body shape information can be predicted using a 3D human body scanner, based upon which a beauty service can be provide.

  • This study focused on the accessory of clothes of minority groups in Yunnan province to further the research about specific accessories' development in the future. Among the minorities in Yunnan, this study centralized characteristics of ornaments, hats and belts among five minority groups such as the Bai, Zhuang, Hani, Dai, and the Zang as representatives to study in detail because these five ethnicities have a relatively long history and plentiful information. The results are as follows: First, exaggeration means large gorgeous patterns that attract attention. Generally, there are many natural resources that can be used in places where these minority groups live such as gems, gold, silver shells and animals' horns, bone, teeth and the like. Headdress includes combs, loops, hairpins and other similar articles. Second, nature is a very fundamental part that people rely on for existence and development. The production and living that people need in life all depend on nature. The design of accessories is made from animal forms and patterns of clothes are presented through embroidery and wax printing. Designers always tried to add natural elements to their works. Third, symbolism consists of two aspects: One is the people's imagination, which related to actual materials, and the other is the product of imagination that provides better conditions to inspire people when they design. In China, most minority groups believe in Buddhism. The symbols in the clothing show their devout faith. Even the method of wear has many special implications like the use of accessories and length of clothing. The pattern of dragons and use of golden, red and other colors all have a proper symbolic significance in modern designs.

  • Selenium is considered to be one of the most controversial trace elements. On the one hand, it is toxic at high doses and there is a great body of information related to environmental issues of Se contamination. On the other hand, Se deficiency is a global problem related to an increased susceptibility to various diseases of animals and humans and decreased productive and reproductive performance of farm animals. Optimisation of Se nutrition of poultry and farm animals will result in increased efficiency of egg, meat and milk production and even more important, will improve quality. From the data presented in the review it is clear that the main lesson which we have to learn from nature is how to use organic selenium in animal and human diets. Selenium-enriched yeast (Sel-Plex) is the result of such a lesson and it is just a matter of time before animal nutrition moves completely from using ineffective sodium selenite to organic selenium. Other lessons from nature will follow. Recent advances in genomics and proteomics, in association with descriptions of new selenoproteins, will be a driving force in reconsidering old approaches related to Se nutrition. Probably 90% of all Se research has been conducted with sodium selenite and we now understand that the natural form of selenium is different. The main advances in Se status assessment and Se requirements were established based on the activity of glutathione peroxidase (GSH-Px), an enzyme which for many years was considered to be the main selenoprotein. Recently it was discovered that it is only one of at least 25 various selenoproteins. Se research and practical applications are developing quickly and they are very exciting and promising.

  • Ubiquitous computing is a study area explained in a myriad of contexts and technological terms. So when you try to define it with simple words, it gets even more confusing. Payment. however, refers in nature to an act of money transfer from one entity to another, and it is obvious that a payment method will be valued as long as the transaction can be completed with safety no matter what technology was used. In the end, the key to U-payment is convenience and security in the transfer of financial information. The purpose of this paper is to find a desirable U-payment scheme by looking at the characteristics of seamlessness under the ubiquitous environments, Strong Personal Device, and peer-based if information transactions. We also propose U-SDT Protocol integrating critical technologies such as Radio Frequency Identification (RFID), Bluetooth, Personal Payment Device, Account Managing Application and Transaction ID as a way to make transactions between users seamless and secure better privacy protection.

  • The importance of urban and regional natural park increases because of the needs for preserving the natural resources and providing with natural recreation space in nature. This planning of natural park management should be established based on the research of the various natural resources in the park. But for the lack of effective data synthesizing methods and concepts, only some restricted factors for zoning plan are considered even though GIS computer system for large complex simulation is used. Therefore, in this study three ecological zoning models such as Basic Factor Model (BFM), Visual Landscape Model (VLM) and Comprehensive Ecological Model (CEM) are proposed and applied to Byounsan Peninsula Nature Park(BPNP) for comparison with the current natural park zoning. The BFM has three components -elevation, slope and vegetation. The VLM has applied with six components -elevation, slope, vegetation, road type, and the visual distance. Finally the CEM's modelling factors have included all of BFM, VLM components are added with the land use type, nature and historic resource factors. The zoning concept of BPNP was based on "Minimization" focused on the specific factors. But introduced modelling concept is "Optimization" based on the total ecological environment. So the result of the modelling has larger area for preservation and development zoning compared with the current zoning whose characteristics are ambiguous which allows the environmental destruction. The future study issues will be the determination of the weighting factor, component reconsideration based on the ground truth data and the agriculture residential area zoning.

  • Active networks allow active node’s functionality to be extended dynamically through the use of active extensions. This flexible architecture facilitates the deployment of new network protocols and services. However, the active nature of a network also raises serious safety and security concerns. These concerns must be addressed before active networks can be deployed. In this paper we look at how we can control active extension’s access to different active nodes. Specifically, the authentication between active nodes is very important in this case. We use unique identity each node has for transferring access policies between active nodes. In this paper, we suggest a new method of transferring access policies performing authentications using identities between active nodes.

  • 교원의 핵심 역량 중 지식 역량이나 수행 역량 등은 교직과정 이수 결과의 확인이나 지필 시험 또는 실기 시연 등을 통해 확인 또는 평가할 수 있다. 그러나 태도 역량이나 전문성 개발역량의 일부 요소들은 별도의 도구나 평가로 심사해야 된다. 전문성 개발 역량 가운데 자기반성 노력, 지속적 학습 노력, 교육 공동체 간 의사소통 및 협력 등의 요소들은 기존의 평가 방식으로 파악하기 어렵다. 따라서 교원의 핵심 역량을 평가하기 위해서는 교직 적성 및 인성 검사와 같은 별도의 도구가 필요하다. 본 논문은 교원자격을 강화하기 위한 교직 적성 및 인성 검사를 효율적으로 실시하기 위한 온라인 웹 검정 시스템을 설계하고자 한다.

  • The Internet has become an increasingly important source for finding the right employees, so more and more companies post their job openings on the Web. The large amount and dynamic nature of career recruiting information causes information overload problems for job seekers. To assist Internet users in searching for the right job, a range of research and commercial systems were developed over the past 10 years. Surprisingly, the majority of existing job search systems support just one, rarely two ways of information access. In contrast, our work focused on exploring a value of comprehensive access to job information in a single system (i.e., a system which supports multiple ways). We designed Proactive, a recommendation system providing comprehensive and personalized information access. To assist the varied needs of users, Proactive has four information retrieval methods - a navigable list of jobs, keyword-based search, implicit preference-based recommendations, and explicit preference-based recommendations. This paper introduces the Proactive and reports the results of a study focusing on the experimental evaluation of these methods. The goal of the study was to assess whether all of the methods are necessary for users to find relevant jobs and to what extent different methods can meet different users' information requirements.
