  • The wafer level stacking with Cu-to-Cu bonding becomes an important technology for high density DRAM stacking, high performance logic stacking, or heterogeneous chip stacking. Cu CMP becomes one of key processes to be developed for optimized Cu bonding process. For the ultra low-k dielectrics used in the advanced logic applications, Ti barrier has been preferred due to its good compatibility with porous ultra low-K dielectrics. But since Ti is electrochemically reactive to Cu CMP slurries, it leads to a new challenge to Cu CMP. In this study Ti barrier/Cu interconnection structure has been investigated for the wafer level 3D integration. Cu CMP wafers have been fabricated by a damascene process and two types of slurry were compared. The slurry selectivity to $SiO_2$ and Ti and removal rate were measured. The effect of metal line width and metal density were evaluated.

  • This paper investigates the influence of the economic integration exemplified by the Eurasian Economic Union on the entrepreneurial ecosystem in the Kazakhstan corporate sector. Using data collected from 204 small-, medium-, and large-sized Kazakh companies, the researchers analyzed the collected data with percentile. Findings of this study show that small- and medium-sized enterprises, especially in the tertiary sector of the Kazakh economy, are not that much affected by regional integration, whereas large firms have been significantly impacted. The originality of the paper is threefold. First, the research explores the entrepreneurial ecosystems in its focus on geographic location or digital technologies that came across mainly from the ICT space. This is becoming pervasive across mechanical systems, communications, infrastructure, and the built-up environment. Second, the originality of the paper lies in focusing on the entrepreneurial ecosystems' influence on the business processes by clearly understanding the regional, national, and international trends in different markets. Third, the paper is first of its kind to contribute an updated perspective on the entrepreneurial ecosystem's influence on economic integration to the policymakers of Kazakhstan. Policymakers will gain expertise on how to manage network effects while planning investment projects, as well as transactions, modes, and fixed nodes, acquisition, and greenfield investments.

  • Multicultural education is not about learning about a specific ethnic group, but rather developing the ability to cross the border of one's own culture and have conversations with people of other cultures. I think the purpose is to promote empathy and consideration. This study emphasizes the importance of developing multi-dimensional educational programs for all members of society for multicultural social integration, and it is necessary to lead personal, social and civic action movements to create a fair society through media-based multicultural literacy education. said that In order to achieve harmony and integration in a multicultural society, it is the most important to acknowledge cultural diversity and to discard cultural prejudices and inequalities for symbiosis between the mainstream culture and the minority culture. In particular, the United States and Germany, which have successfully led multicultural social integration, are comprehensive in all areas, including interculturalism based on peaceful coexistence and respect, labor market issues, vocational education issues, housing and health issues, and communication issues through media literacy. He led a multicultural national integration system with approaches and methods. Therefore, our multicultural education policy should also pursue a new paradigm that presupposes a change in the public's awareness of a multicultural society.

  • Objectives: This study was performed to investigate the association between hopelessness, social support and community integration, and depression. Methods: We analyzed data from a questionnaire administered to subjects aged 65 years or older living alone for a 2015 community mental health project in Gyeongnam S city. We used a correlation analysis and a hierarchical regression analysis to identify factors that affect depression. Results: When controlling for socio-demographic factors, hopelessness and community integration had significant effects on depression. That is, the higher the hopelessness (B=0.768, p<.001) and the lower the community integration (B=-0.163, p=.012), the higher the depression in elderly living alone. Conclusions: There is a need for approaches at both the individual and social levels that consider and improve measures to prevent and reduce depression. Moreover, it is especially necessary to enhance community integration.

And we also provided various analysis pipelines, NGS analysis (Reference assembly, RNA-seq), GWAS, Microbial community analysis. In addition, the our system was carried out based on the design and build the quality assurance in management omics information system and constructed the infrastructure for utilization of omics analyze system. We carried out major improvement quality of omics information system. First is Improvement quality of registration category for omics based information. Second is data processing and development platform for web UI about related omics data. Third is development of proprietary management information for omics registration database.

  • One of the most important issues in post-genome era is identifying functions of genes and understanding the interaction among them. Such interactions from complex biochemical pathways, which are very useful to understand the organism system. We present an integrated biochemical pathway database system with a set of software tools for reconstruction, visualization, and simulation of the pathways from the database. The novel features of the presented system include: (a) automatic integration of the heterogeneous biochemical pathway databases, (b) gene ontology for high quality of database in the integration and query (c) various biochemical simulations on the pathway database, (d) dynamic pathway reconstruction for the gene list or sequence data, (e) graphical tools which enable users to view the reconstructed pathways in a dynamic form, (f) importing/exporting SBML documents, a data exchange standard for systems biology.

  • The purpose of this paper is to evaluate environmental friendliness for facilities of national park to improve naturalness of national park. We have evaluated environmental friendliness of the facilities in Chirisan national park in terms of resource conservation and environmental integration, which are consisted of 9 and 8 evaluation indicators, respectively. Environmental friendliness of the small facilities was not good due to not using locally obtained materials and natural material, and that of large and complex facilities was bad in the field of excessive damage during construction, inadequate maintenance, use of natural material, locally obtained material, environmental integration with surroundings. In evaluating environmental attributes, new facilities is better than the older ones. The small facilities appeared to be worse than those of the complex, and the large facilities are the worst in terms of environmental friendliness. In general, environmental friendliness turned out to be lower in the light of the facilities in the clustered area than those of the facilities of the other area. In the future, It is required that criteria for evaluating environmental friendliness of natural park facilities is established.

  • Robotics has been increasing its role among factors affecting teachers' technological, pedagogical, and content knowledge(TPACK) in education. This paper reviews these factors and analyses each to identify those most influential: teachers' individual (gender, teaching experiences), professional development(PD) for technology integration, psycho-philosophical characteristics (attitude toward technology integration, constructive belief), and school characteristics.Those having the most significant influence on teachers' TPACK of robotics were PD for technology integration from individual characteristics, attitudes toward technology integration, educational belief from psycho-philosophical characteristics, and schools' atmosphere and support from school characteristics.Thisreview confirmed that PD for technology integration and school atmosphere are the two most influential factors among all factors considered. Practical implications on precautions for effective integration of robotics in education were identified.
