  • This study presents a new computational model to analyze the grain deformation in a polycrystalline aggregate in a discrete manner and based directly in the underlying physical micro-mechanisms. As a result, specific characteristics have to be considered for the numerical analysis. The grains and grain boundary elements are introduced to model individual grains and grain boundary facets, respectively, to consider the size effects in the micro forming. The constitutive description of the grain elements accounts for the rigid-plastic and the grain boundary elements for elastic relationships. The capability of the proposed approach is demonstrated through application of grain element and grain boundary element in the micro forming.

  • This study presents a new computational model to analyze the grain deformation in a polycrystalline aggregate in a discrete manner and based directly in the underlying physical micro-mechanisms. When scaling down a metal forming process, the dimensions of the workpiece decrease but the microstructure of the workpiece remains the similar. Since the dimensions of the workpiece are very small, the microstructure especially the grain size will play an important role in micro forming, which is called size effects. As a result, specific characteristics have to be considered for the numerical analysis. The grains and grain boundary elements are introduced to model individual grains and grain boundary facets, respectively, to consider the size effects in the micro forming. The constitutive description of the grain elements accounts for the rigid-plastic and the grain boundary elements for visco-elastic relationships. The capability of the proposed approach is demonstrated through application of grain element and grain boundary element in the micro forming.

  • This study was intended to examine the change in the perception of the professionals for the environment-friendly apartments. After result of implementing the question survey against the professionals two times, the degree of importance in the environment-friendly design elements didn't show any significant change. However, it showed the degree of maturity on the concept of environment-friendly development is widely spreaded in terms of social, economic and environmental aspects. Based on the description of such results, the conclusion can be deduced as follow; 1) Presumably it would require 5 years for the diffusion of the concept of environment-friendly apartments and 10 years for the construction of developing its materialization and settlement respectively, 2) The proper density would be designed in $150{\sim}200%$ in view of the environmental and economic aspects. 3) It is necessary to change the existing system into the District Unit oriented planning & design method in order to apply the environmental design elements in smooth manner.

  • Under the background of the rapid development of digital educational games, we have to evidently research the elements of the achievement system of children's DEG (Digital Educational Game), and analyze the relations between the elements and make a profound study on the achievement system and its components on the impact of player's attitude. Compared with the existing research, the research contents and methods are innovative and reliable. The results show that players have a positive attitude towards the DEG achievement system, DEG achievement system has important value and role for educational games. Which is made of five elements: symbol, reward, logic, social interaction, and knowledge. The five elements interact with each other and have a positive impact on players' attitudes. DEG achievement system with five elements will bring players a positive experience. These findings provide a detailed study of the components of the achievement system. With all of these, we can explain the role and relationship of the components, and provide new ideas and empirical evidence for the design and development of children's educational game achievement system. The above findings provide a detailed description of the components of the DEG achievement system, explain the role and value of each component, and the relationships and patterns among the components, it provides a new perspective and empirical evidence for the design and development of the children's system DEG results.

  • Graphical user interface(GUI) has a very important role to interact with software users. However, designing and coding of GUI are tedious and pain taking processes. In many studies, the researchers are trying to convert GUI elements or widgets to code or describe formally their structures by help of domain knowledge of stochastic methods. In this paper, we propose the GUI elements detection approach based on object detection strategy using deep neural networks(DNN). Object detection with DNN is the approach that integrates localization and classification techniques. From the experimental result, if we selected the appropriate object detection model, the results can be used for automatic code generation from the sketch or capture images. The successful GUI elements detection can describe the objects as hierarchical structures of elements and transform their information to appropriate code by object description translator that will be studied at future.

  • The purpose of this study was to develop a standardized job description for dietitians using the DACUM technique. To examine the validity of job description through DACUM, dietitians were surveyed relative to importance, performance, and difficulty. The survey was conducted April 1-30, 2014. A total of 217 questionnaires were used in the analysis. The final developed job description for dietitians included six duties, 38 tasks, and 210 task elements. DACUM's findings include six duties: nutrition management, food service operation management, hygiene safety management, community food and nutrition program management, organization management, and professionalism strengthening. There were 5.1 points regarding importance, 4.1 points regarding performance, 4.9 points regarding difficulty, and statistically significant differences (p<0.001). Dietitians responded that 'nutrition management' and 'hygiene safety management' were the most important. 'Hygiene and safety management' showed the highest performance, and 'community food and nutrition program management' and 'professionalism strengthening'' showed the highest difficulty. Thus, it is considered that the job analysis results can be used to evaluate and improve the subjects' training program. Dietitians' jobs are subject to various environmental changes, such as demographic changes, health care system changes, and the development of the food industry, and thus, should be reviewed and analyzed periodically.

  • 정보산업의 발달로 다양한 기록매체가 출현함에 따라 시청각기록물의 생산량과 이용률이 급증하였으나, 시청각기록물에 대한 인식은 부수적인 가치를 지닌 별도의 기록물로 취급되고 있다. 이와 같이 시청각기록물을 소장하고 있는 기관들은 그 형태의 종류와 보관방법 등의 부분에서 상당히 취약한 면모를 보이고 있으며, 관리하는 방식도 모두 다르기 때문에 이용자들이 시청각기록물의 검색 및 활용에 불편을 겪고 있다. 따라서 본 연구는 국내 주요 기관에서 사용되고 있는 시청각기록물 기술요소의 비교 분석을 통해 시청각기록물의 통합관리 가능성을 조사하였다. 이를 통해 시청각기록물의 기관별 메타데이터 요소와 기관 간 통합관리 가능성을 파악하며, 각 기관에서의 효율적인 시청각기록물의 관리 검색 서비스 제공과 이용에 대한 효과를 제안하고, 시청각기록물의 통합 메타데이터 기술요소 개선안을 제시하였다.

  • In this paper we describe SLA metrics and software architecture for newly upcoming IP TV service. Firstly we show the general description for IP TV. This consists of brief description of IP TV, the general figure of configuration and elements of IP TV network and communication protocol stack of IP TV data transmission for deriving communication quality parameter. And we propose SLA metrics depending on quality measurement point. According to the measurement point the measurable SLA metrics are different. The total view of the IP TV SLA measurement and management architecture is shown. When the quality measurement point is the routers that consist of internet node, the IP media NMS is the quality collection system. And when the quality measurement point is the IP TV STB(Set-Top Box), the IP media collector and Quality Collection Server are the quality collection system. And we show the software block diagram of IP TV SLA processing system and the other related network management systems.

  • 인터넷을 통하여 텍스트나 음성, 화상자료 등 다양한 정보를 이용할 수 있지만 이러한 전자정보원에 접할 수 있는 체계적인 서지통정이 아직 확립되어 있지 않다. 이 논문은 전자정보원의 체계적인 서지통정을 위한 규범이 되고 있는 국제표준서지기술법 ISBD(ER)을 중심으로 ISBD(CF)에서 ISBD(ER)로 변경된 배경과 함께 최근의 목록작성에 대한흐름을 개관하고, ISBD(ER)가운데 특징적인 서지요소와 기술규칙을 분석한 후 이를 바탕으로 AACR2R, OCLC 매뉴얼. CCM Module 31. 그리고 USMARC와 함께 검토함으로써 원격 전자정보원의 서지기술에 있어서 관련규칙들의 문제점과 특성을 비교 분석하였다.
