  • In the first part of this talk, I will introduce an effort to use gold nanoparticles and UO22+ (uranyl) specific DNAzyme for development of highly sensitive and selective colorimetric uranyl sensors. In addition, I will discuss how DNA aptamers can be delivered by nanoparticles to cancer cell nucleus and released by ultrafast femtosecond pulsed laser for targeted cancer therapy. Finally, I will show how proteins such as streptavidin and myoglobin, or nanoparticles can be precisely aligned on DNA with nanometer resolution via backbone-modified phosphorothioate DNA and bifunctional linkers. These interesting functional and structural properties of DNA can provide new opportunities to develop dynamic DNA structures for potential use as intracellular sensors and drug delivery agents.

  • "Artificial Intelligence+" is a key strategic direction that has garnered the attention of several global medical device manufacturers and internet companies. Large hospitals are actively involved in different types of medical AI research and cooperation projects. Medical AI is expected to create numerous opportunities and advancements in areas such as medical imaging, computer aided diagnostics and clinical decision support, new drug development, personal healthcare, pathology analysis, and genetic disease prediction. On the contrary, some studies on the limitations and problems in current conditions such as lack of clinical validation, difficulty in performance comparison, lack of interoperability, adversarial attacks, and computational manipulations are being published. Overall, the medical AI field is in a paradigm shift. Regarding international standardization, the work on the top 10 standardization issues is witnessing rapid progress and the competition for standard development has become fierce.

  • Recently, the roles of the construction engineers become more important in all phases of construction project life cycle. Construction engineers' capabilities is one of the key factors to accomplish construction project objectives. After acquiring basic Knowledge and skills in colleges, the construction engineers have opportunities to develop their abilities through continuous education provided by companies, associations, colleges, and so on. The current eduction system is not sufficient enough to assist engineers to develop their potentials. The construction professionals training system that help career development, career management, education and training is need to raise excellent engineers in a long term perspective. In order to investigate the necessity and the element in the career development support, I perfromed the perception about the career deveolopment by doning question investigation.

  • The purpose of this paper is to present some main economic factors which influence Gaza Seaport. Without direct access to the international market, the Palestinian economy will continue its dependence on Israeli economy mainly in employment, transport facilitation, and international trade. The greatest potential for Palestinian economic growth lies in trade. The port is important for creating new job opportunities, and for enhancing exporting capabilities, which are the most essential elements for development of the Palestinian economy. Israeli policies and procedures incur Palestinian exporters additional transportation costs when delivering their products to Israeli Ports or when transit these products to neighboring countries through Israeli controlled area. The public profit for the port is greater than the private profit. Therefore, constructing the port will have a great effect on the Palestinian economy. There are many challenges facing the port, some of them are the political stability, the economies of scale, and Israeli security measures and procedures.

  • As North Korea signed 'the Korea Peninsula Non-Nuclearization Joint Declaration' at the end of last year as well as full-scope safeguards agreement with the IAEA in Jan.30 1992, her nuclear activity was incorporated into the international monitoring system and opportunities were arranged to .obstruct her nuclear weapon development and nuclear material diversion, which have been international issues up to recent years. However, achieving goals of the Joint Declaration and safeguards agreement should presuppose North Korea's sincerity toward the abandonment of nuclear weapon development. In this study, first of all, her nuclear policy, current situation of nuclear development and the capability of nuclear development are analyzed. Also, based on the analysis. attempts have been made to find methods of effective performance of the South-North Korea mutual nuclear inspection and the suggested methods are as follows; 1) Analysis of the limits of IAEA inspection and suggestion of its supplementary strategies 2) Securing and training professional inspectors for the South-North mutual inspection 3) Establishment of the verification technology to detect nuclear material diversion.

  • As the weapon systems of the 21st century are becoming more and more performance /technoloriven, it is only becoming more expensive to obtain the weapon systems. Therefore, it is absolutely vital for every nation to find a way to reduce cost objectives. As CAIV is a strategy that entails setting aggressive, yet realistic cost objectives when defining operational requirements and acquiring defense systems and managing achievement of these objectives, we believe that it is essential for us to find out what it is and how we can adopt it so that we can provide ourselves with highly capable systems that are affordable. Therefore, In this paper we will give a brief overview of CAIV that is one of the main acquisition strategies adopted by DoD of U.S. including some case studies of CAIV. Furthermore, the paper will analyze stated cost objectives in our country and suggest realistic opportunities for cost reduction.

  • Proof serves a critical role in mathematical practices as well as in fostering student's mathematical understanding. However, the research literature accumulates results that there are not many opportunities available for students to engage with proving-related activities and that students' understanding about proof is not promising. This unpromising state of instruction of proof calls for a novel approach to address the aforementioned issues. This study investigated an instruction of proof to explore a pedagogy to teach how to prove. The teacher utilized the way of problem posing to make proving a routine part of everyday lesson and changed the classroom culture to support student proving. The study identified the teacher's support for student proving, the key pedagogical changes that embraced proving as part of everyday lesson, and what changes the teacher made to cultivate the classroom culture to be better suited for establishing a supportive community for student proving. The results indicate that problem posing has a potential to embrace proof into everyday lesson.
