Enterprise Content Integration (ECI)is an IT strategy that improves enterprise' competitive advantages by integrating enterprise wide information and content into a unified view, which in turn supports efficient and effective decision making. Content Syndication Systems (CSS) is a solution that implements the ECI strategy. In semi-conductor industries, it is usual that enterprise content is scattered over tens of legacy systems. Therefore, engineers in semi-conductor companies spend a few hours to locate required engineering information on a daily basis as part of their jobs. In this paper, we develop an enterprise CSS system that integrates enterprise wide contents into a unified view that is suitable for semi-conductor industries. For this research, we first define enterprise CSS, then identify their systems requirements. Then we propose an architecture supporting the identified requirements, and present the implemented prototype. One of the most important requirements is the individualized subscription rule setting for engineering information. For this purpose, we developed methods to represent the information properties and subscription rules.

A role of Distribution Automation System(DAS) is required to be changed from observing and control to complex and various new system including functions which monitoring, control, prediction, operation and management of EMS type according to be gradually Smart Grid of distribution operation system for development of further power system industrial. IEC(International Electrotechnical Commission) published communication standards which interface and data model of distribution operation system to IEC 61968 and of host system like EMS(Energy Management System) to IEC 61970. So far, each standards are emphasizing themselves, but if they are applied by designed integration of the standards, it could be more efficiency system. So, in this paper, integration application of IEC standards and structure of further distribution operation system to use them are proposed by gradually increasing importance of communication protocols, functions and roles in further distribution management system considering Smart Grid.

Legacy utilities can not adapt to changing business conditions without having complete control of operational systems and a flexible infrastructure that supports change. What is needed is a framework that enables data to be coalesced and transformed in to usable knowledge. This framework should be robust enough to that as new situations arise, information can be shared in ways not previously anticipated. Utility Integration Bus (UIB) provides an integration framework which solves many of these issues while controlling complexity. This paper provides UIB's overview and course.

When manufacturing mold dies, an operation sheet is required for each part of the mold dies. The consistent estimation of standard operation time in the operation sheet is difficult, because the estimation is mainly based on subjective judgement. In order to resolve it, concept of feature is introduced in this study. For CAD/CAPP integration, feature technology is being implemented to represent geometrical and technological information of part drawings. A feature database has already been designed, and then used to generate data for process and operation planning modules. Related to this former research, standard operation time is calculated using the feature information and tables used in a real factory.

The rapid increase in genetic dataset volume has demanded extensive adoption of biological knowledge to reduce the computational complexity, and the biological pathway is one well-known source of such knowledge. In this regard, we have introduced a novel statistical method that enables the pathway-based association study of large-scale genetic dataset-namely, PHARAOH. However, researcher-level application of the PHARAOH method has been limited by a lack of generally used file formats and the absence of various quality control options that are essential to practical analysis. In order to overcome these limitations, we introduce our integration of the PHARAOH method into our recently developed all-in-one workbench. The proposed new PHARAOH program not only supports various de facto standard genetic data formats but also provides many quality control measures and filters based on those measures. We expect that our updated PHARAOH provides advanced accessibility of the pathway-level analysis of large-scale genetic datasets to researchers.

과거 건설사업관리업무를 수행하는 건설사 업무담당자들은 방대한 보고자료를 발주기관으로 전송할 경우 주로 웹하드를 이용하였다. 그러나, 최근 개인정보 유출 등 각종 인터넷 보안사고가 빈번히 발생함에 따라 발주기관별로 기관 내부망과 외부망으로 분리하여 네트워크 보안을 강화하는 추세에 있다. 이에 따라, 건설사에서 발주기관으로 대용량 파일을 전송하지 못함으로서 발주청의 건설사업관리 업무처리에 어려움이 발생하였다. 이러한 문제를 해결하기 위하여 본 연구는 망분리 환경하에서 특정 사용자만을 위한 자료 공유체계를 마련하였다.

Two main technologies of III-V/Si laser diode for optical communication, direct epitaxial growth, and wafer bonding were studied. Until now, the wafer bonding has been vigorously studied and seems promising for the ideal III-V/Si laser. However, the wafer bonding process is still complicated and has a limit of mass production. The development of a concise and innovative integration method for silicon photonics is urgent. In the future, the demand for high-speed data processing and energy saving, as well as ultra-high density integration, will increase. Therefore, the study for the hetero-junction, which is that the III-V compound semiconductor is directly grown on Si semiconductor can overcome the current limitations and may be the goal for the ideal III-V/Si laser diode.

Based on the capture-emission energy (CEE) maps of CMOS devices, a physics-informed machine learning model for the bias temperature instability (BTI)-induced threshold voltage shifts and low frequency noise is presented. In order to incorporate physics theories into the machine learning model, the integration of artificial neural network (IANN) is employed for the computation of the threshold voltage shifts and low frequency noise. The model combines the computational efficiency of IANN with the optimal estimation of Gaussian mixture model (GMM) with soft clustering. It enables full lifetime prediction of BTI under various stress and recovery conditions and provides accurate prediction of the dynamic behavior of the original measured data.

Under the context of the recent curriculum reform in Mongolia emphasizing technology integration in schools, the main purpose of this study was to examine external and internal factors that influence teachers' use of technology. This study aimed to investigate structural relationships between school support, technology use, and TPACK (Technological Pedagogical and Content Knowledge) among Mongolian secondary school teachers. This study was conducted with 208 secondary school teachers in Ulaanbaatar, Mongolia. Data were collected through an instrument that measures three factors: teachers' use of technology, TPACK, and school support. The results indicate that TPACK has a partial mediation effect on the relationship between school support and the use of technology. The contribution of this study lies that it examines the complex relationships between internal and external factors affecting teachers' technology integration, especially among Mongolian teachers who are less researched in the existing literature.

This study explored the effects of the parasocial relationship formed by CCTV (China Central Television) TV news and non-traditional news on users' perceived media credibility and their online and offline political participation. This study conducted a survey with the Chinese CCTV users between April 19 and April 30, 2021, and finally, 701 respondents' data were analyzed using structural equation modeling. The study results showed that both TV news and non-traditional news had positive effects on parasocial relationships and the parasocial relationship positively influenced media credibility, which subsequently facilitated political participation. However, there was no direct effect between media usage and media credibility. This implies the important mediating role of parasocial interactions, which enables CCTV news to gain media credibility and subsequently influence political participation. This study suggests that CCTV needs to improve the parasocial interactions between their audience and media figures by utilizing the interactive mechanism of non-traditional media.
