  • Finite element analysis is one of the most used tools for studying femoral neck fracture. Nerveless, consensus concerning either the choice of material characteristics, damage law and /or geometric models (linear on nonlinear) remains unreached. In this work, we propose a numerical quasi-brittle damage model to describe the behavior of the proximal femur associated with two methods to evaluate the Young modulus. Eight proximal femur finite elements models were constructed from CT scan data (4 donors: 3 women; 1 man). The numerical computations showed a good agreement between the numerical curves (load - displacement) and the experimental ones. A very encouraging result is obtained when a comparison is made between the computed fracture loads and the experimental ones ($R^2=0.825$, Relative error =6.49%). All specific numerical computation provided very fair qualitative matches with the fracture patterns for the sideway fall simulation. Finally, the comparative study based on 32 simulations adopting linear and nonlinear meshing led to the conclusion that the quantitatively results are improved when a nonlinear mesh is used.

  • The importance of selection methods of secondary school teachers have gathered attention due to their enormous influence on the pre-service education programs. However, scholars and practitioners are skeptical about the effectiveness of the measures, especially under the condition of teacher oversupply found in South Korea and China. Based on this problem statement, this study seeks to compare the secondary teacher employment methods of the two countries to better understand the situations as well as to draw implications for improvement. We reach the following conclusions through comparative analyses. First, the reforms of the teacher employment system in both countries have been triggered by the quantitative supply concerns not by the qualitative concerns. Second, both countries require teaching license as a precondition of employment, while their quality assurance measures for the license reveal critical limitations. Third, both countries have attempted to improve selection methods; nevertheless, oversupply of prospective teachers makes objectivity and fairness more important than the appropriateness. Based on the conclusions, policy implications focusing on the quality-oriented approach are suggested in order to employ effective secondary teachers who can contribute to the quality improvement of school education.

  • Introduction: Return-to-work (RTW) can be a problematic occupational issue with detrimental impact on the quality of life of previously-employed breast cancer survivors. This study explored barriers and facilitators encountered during the RTW process in the area of cancer survivorship. Materials and Methods: Six focus groups were conducted using a semi-structured interview guide on 40 informants (employed multiethnic survivors). Survivors were stratified into three groups for successfully RTW, and another three groups of survivors who were unable to return to work. Each of the three groups was ethnically homogeneous. Thematic analysis using a constant comparative approach was aided by in vivo software. Results: Participants shared numerous barriers and facilitators which directly or interactively affect RTW. Key barriers were physical-psychological after-effects of treatment, fear of potential environment hazards, high physical job demand, intrusive negative thoughts and overprotective family. Key facilitators were social support, employer support, and regard for financial independence. Across ethnic groups, the main facilitators were financial-independence (for Chinese), and socialisation opportunity (for Malay). A key barrier was after-effects of treatment, expressed across all ethnic groups. Conclusions: Numerous barriers were identified in the non-RTW survivors. Health professionals and especially occupational therapists should be consulted to assist the increasing survivors by providing occupational rehabilitation to enhance RTW amongst employed survivors. Future research to identify prognostic factors can guide clinical efforts to restore cancer survivors to their desired level/type of occupational functioning for productivity and wellbeing.

  • The aging process is multifactorial and results from the combined effects of inherited(genetic) and acquired factors including life style, food habits, physical activity, and diseases. That give rise to the various approaches in aging. We are trying to study biological changes with aging, In detail we are focused on gene and protein function accompanied by normal or abnormal aging process, especially our efforts are aimed at revealing the functional relationship of proteins in aging as a final product of gene. We expect that proteomic approach to the study of protein function involved in aging should give us variety of integrated data to understand biological changes of long lived lives, We have applied expression proteomics to rat liver bred in dietary restriction or in at libitum to elucidate the effects of food habit on aging. Expression proteomics shows us protein profile in a selected tissue or cells as a whole and gives us the information about protein expression level, posttranslational modification and degenerative modification of expressed proteins. Comparative analysis of young and old rat liver by two dimensional gels shows that gene expression of several proteins was down regulated in old rats and some protein expression level is increased with aging. Dietary restriction slows down these changes of gene expression and in some proteins there's no difference in protein expression level at same ages in comparison with rats bred in at libitum. About forty protein was identified by peptide mass fingerprint with MALDI-TOF and rest of the protein of interest is in the course of identification, Also we are trying to make mitochondrial and cytosolic proteom reference map. These suborganelle proteom map will gives us the information about low abundance proteins and cellular localization of proteins. Proteomics is a growing methodology to study biological system. High throughput qualitative and qualitative aspect of this approach will gives us large amount of integrated information and speed up our understanding about biological system

  • Since the Korean economic development path has been unique compared to other counties, it is necessary to build an incubation ecosystem matching with unique economic environment in Korea. In order to revive the dynamism of the economy, establishment of the incubator ecosystem should be a policy priority so that ventures with innovative ideas and challenging minds can grow into a global stage. The purpose of this study is to derive the policy implications for establishing ecosystem and infrastructure by comparing to other OECD countries such as US, Israel, Finland, and Japan that can offer meaningful policy implications to Korea. For this purpose, the most appropriate model for explaining the incubation ecosystem in Korea was designed. PCII Model (People, Capital, Incubating, Infra) has 4 elements. It provides a framework for incubation of entrepreneurship, funding for start-up, incubation course, establishment of business foundation infrastructure. The comparative analysis was conducted with 12 sub-items under 4 elements and qualitative and quantitative evaluations were performed for each category. As a result of the comparative analysis, Korea's incubation policy seems to be still in the initial stage in terms of establishment of ecosystem compared to other countries. Therefore, a systematic approach based on the ecosystem model is needed other than the short-term incubation policy.

  • Australian Curriculum Assessment and Reporting Authority(ACARA) was founded by Australian federal government in 2009. Leading under ACARA, national education curriculum development was propelled. Also from 2014 they gradually extended enforcement of new curriculum by a Reminder about new syllabus implementation (2013.01.29.). The research result of Australia's curriculum, and textbook shows that students repeat, and advance the same contents under spiral curriculum as they move to higher grade. They actively use digital technology, and also puts emphasis on practical context such as Money & financial mathematics. On the level of difficulty, or quantity aspect, Korea handles relatively advanced contents of 'number and operation' or 'Letters and Algebraic Expressions' domain than Australia. However on statistics domain, Australia not only puts more focus on practical stats than Korea, but also concerns as much on both various and qualitative terms Australia doesn't deal with formal concept of 'function'. However, they learn the wide concept of function by handling various graphs. This shows Australia has a point of similarity, and also difference to Korea on various angles.
