본 연구에서는 지하시설물도 구축에 기존의 수치지도 및 편집지적도의 대안으로 가독성 및 일반인의 접근성을 높인 항공사진을 사용하여 하수 지하시설물도를 시범구축 하였다. 구축된 하수 지하 시설물도는 기존의 편집지적도기반 지하시설물도와 연계하여 그 활용 가능성 및 정합성 연구를 수행하였다. 지적도와 항공사진을 융합하여 지하시설물도를 구축 활용하면 지하시설물에 대한 다양한 공간정보 분석과 체계적이고 종합적인 통합정보 활용이 가능하다. 또한, 고도정보화 사회에서 항공사진을 이용한 지하시설물도 작성은 관리기관별로 존재한 도면 및 기존 도면의 사용에 따른 문제점에 대한 대안으로 통합관리를 위한 기본도로서의 구실을 할 수 있을 것으로 판단된다. 또한, 항공사진을 이용한 하수 지하시설물도 구축 정보는 앞으로 도시정보시스템 구축에 연계하여 체계적인 도시계획의 수립 및 관리의 효율 성도 도모할 수 있을 것으로 생각한다.

Cell type specification is a delicate biological event in which every step is under tight regulation. From a molecular point of view, cell fate commitment begins with chromatin alteration, which kickstarts lineage-determining factors to initiate a series of genes required for cell specification. Several important neuronal differentiation factors have been identified from ectopic over-expression studies. However, there is scarce information on which DNA regions are modified during induced pluripotent stem cell (iPSC) to neuronal progenitor cell (NPC) differentiation, the cis regulatory factors that attach to these accessible regions, or the genes that are initially expressed. In this study, we identified the DNA accessible regions of iPSCs and NPCs via the Assay for Transposase-Accessible Chromatin sequencing (ATAC-seq). We identified which chromatin regions were modified after neuronal differentiation and found that the enhancer regions had more active histone modification changes than the promoters. Through motif enrichment analysis, we found that NEUROD1 controls iPSC differentiation to NPC by binding to the accessible regions of enhancers in cooperation with other factors such as the Hox proteins. Finally, by using Hi-C data, we categorized the genes that directly interacted with the enhancers under the control of NEUROD1 during iPSC to NPC differentiation.

One of the biggest challenges that the software industry is facing today is to create highly efficient applications without affecting the quality of healthcare system software. The demand for the provision of software with high quality protection has seen a rapid increase in the software business market. Moreover, it is worthless to offer extremely user-friendly software applications with no ideal security. Therefore a need to find optimal solutions and bridge the difference between accessibility and protection by offering accessible software services for defense has become an imminent prerequisite. Several research endeavours on usable security assessments have been performed to fill the gap between functionality and security. In this context, several Multi-Criteria Decision Making (MCDM) approaches have been implemented on different usability and security attributes so as to assess the usable-security of software systems. However, only a few specific studies are based on using the integrated approach of fuzzy Analytic Network Process (FANP) and Technique for Order of Preference by Similarity to Ideal Solution (TOPSIS) technique for assessing the significant usable-security of hospital management software. Therefore, in this research study, the authors have employed an integrated methodology of fuzzy logic, ANP and TOPSIS to estimate the usable - security of Hospital Management System Software. For the intended objective, the study has taken into account 5 usable-security factors at first tier and 16 sub-factors at second tier with 6 hospital management system softwares as alternative solutions. To measure the weights of parameters and their relation with each other, Fuzzy ANP is implemented. Thereafter, Fuzzy TOPSIS methodology was employed and the rating of alternatives was calculated on the foundation of the proximity to the positive ideal solution.

Purpose: This study examines the effects of integrating Evidence Based Practice (EBP) into a critical care clinical practicum on nursing students' access and use of information resources and EBP competency. Methods: A one-group pretest-posttest design was used. Fifty senior nursing school students from a university participated. A critical care clinical practicum combined with EBP consisted of six full days of clinical practicum in intensive care units with EBP education. Group and individual training in EBP skills, lectures, small group discussion and conferences were provided. Data were analyzed using paired t tests for 50 participants. Results: The scores of evidence based practice competency increased significantly (p<.001) showing significant improvement in searching and classifying the evidence. Nursing students' access and use of research evidence improved (p=.004). Conclusion: This study showed that the integration of EBP into a clinical practicum was effective in improving accessibility and usefulness in research evidence such as guidelines and research articles, and increasing EBP competency in undergraduate students.

Platform Screen Door, PSD, is a device that seeks to prevent accidents with regards to falling off the platform and getting trapped between the trains, achieve improvements on the cleanliness of the air, address the accessibility issue of the disabled and the elderly and provide fresher environment on the platform in general. This is achieved by preventing health hazards and accidents from occurring through installation of fixed and moving doors between rail, tram and subway platforms and the railway. Domestic firms have achieved domestic production to a large degree in various Control Units including the Overall Control Unit and RF devices through investments in technology. Despite this, full domestic production of the core of the PSD system, Door Control Unit, DCU, is not yet achieved, having to install PSDs in a relatively short period of time. Currently, controllers with DC motors are developed for installation or one is faced with having to import foreign produced controllers. In this research, the control unit prototype using the BLDC motor was domestically produced. The performance of the control unit was rigorously tested through installation on Eun-Ha Rail on Wol-Mi Island.

There is a need for research to identify the integrated, rather than fragmented, factors that determine users' acceptance of Internet shopping. Using the newly revised technology acceptance model (TAM) as a theoretical framework, this study investigates the effect of a set of information systems quality (information quality and system quality) and trust on intention to use Internet showing through perceived ease of use and perceived usefulness. Using structural equation modeling, the results strongly support the utilization of TAM in predicting users' intention to use Internet shopping, and demonstrates the effects of critical external variables on behavior intention through perceived ease of use and perceived usefulness. Systems quality such as response time, accessibility, and usability has significant effects on perceived ease of use of Internet shopping. Futhermore, trust has also a significant effect on perceived usefulness, perceived ease of use, intention to use Internet shopping, and actual usage of Internet shopping. Based on these results, this study suggests managerial implications of new Internet shopping strategies, focusing on the integration of information systems quality and trust in order to achieve sustainable competitive advantage in Internet shopping.

It has been proved that information and communication technology (ICT) solutions for personalized health (PHealth) and ambient assisted living (AAL) can support people in their daily life activities. Several solutions have been demonstrated to empower different levels of services through seamless data acquisition and specific users' interaction modalities. Usually services usability and accessibility are handled in the design process and are validated with small users' groups. Moreover, while service design and systems development have been extensively described in literature, service deployment methodologies are not properly addressed and documented. Proper reference guidelines are also missing. The most common methodologies like unified process (UP) or ICONX can cover only the design and the development of PHealth services without a clear description on the following phases such as deployment, service provision and maintenance. These phases present several risks to be taken into account right from the beginning of the implementation of PHealth or AAL services. This paper focuses on the description of a structured methodology to deploy PHealth services and how this process can be supported by integrated software routines and adapting the UP framework in particular the "Transition phase."
