Anonymity online has been an ever so fundamental topic among journalists, experts, cybersecurity professionals, corporate whistleblowers. Highest degree of anonymity online can be obtained by mimicking a normal everyday user of the internet. Without raising any flags of suspicion and perfectly merging with the masses of public users. Online Security is a very diverse topic, with new exploits, malwares, ransomwares, zero-day attacks, breaches occurring every day, staying updated with the latest security measures against them is quite expensive and resource intensive. Network security through anonymity focuses on being unidentifiable by disguising or blending into the public to become invisible to the targeted attacks. By following strict digital discipline, we can avoid all the malicious attacks as a whole. In this paper we have demonstrated a proof of concept and feasibility of securing yourself on a network by being anonymous.

Steel frame factories were surveyed in this study in order to explore the possibility of shortening the construction time and save on construction cost through overlapping at the stages of design or construction. In the survey, construction professionals were interviewed in order to collect quantitative data. Hypotheses were then formulated, and the data was thereby analyzed using the simulation technique in order to analyze the effects of the concurrent engineering method on shorter construction time and cost saving. In addition, actual cases were analyzed to determine the overlapping rates of major processes in terms of shorter construction time and cost saving and to analyze the relationship between time and cost due to overlapping.

Analytical hierarchy process (AHP) is a potential decision making method in management that can be used in project management as well. Lack of productivity is perhaps the number one problem confronting in the construction industry. There are numerous factors which affect the productivity of a construction project, so it is necessary to find out the critical factors giving birth to productivity. In this paper, construction productivity is taken as example for the demonstration of the AHP application to find out the critical productivity factor in which the Level 1 is taken as selection of critical productivity factor, Level 2 as construction parties and Level 3 as productivity factors group. The outcome of this study is beneficial to the entire constructional professionals for applying the AHP.

Nowadays the Design-Build Delivery Method in public sector has been remarkably grown up in applying owing to its merits such as shortening construction duration. The Fast-Track is the wide-using method for accelerating schedule at Design-Build projects. But the public agency is in trouble to execute Fast-Track because of the lack of guideline for its process. As a result, in some cases applying Fast-Track methods, cost and construction duration are increased more than cases of non-Fast-Track projects. In this study, through the questionnaire surveys to professionals having actual implementation experiences as a construction manager, owner or general contractor, key success vehicles of Fast-Track are induced.

Web-based collaboration platforms present construction project teams with an opportunity to improve the efficiency of document exchange, better control project communications and enhance team collaboration. However, many construction professionals are still not convinced that these platforms, in their current form, are fit-for-purpose and yield sufficient efficiencies for the construction procurement process. In an attempt to improve the current ICT diffusion process, this paper evaluates the implementation of a web-based collaboration tool on the Lane Cove Tunnel (LCT) project in Sydney, Australia. Moreover, the paper provides strategies for achieving more effective implementation of web-based collaboration platforms in the construction sector.

Prefabrication is a construction technique that is increasingly being applied to different building components due to its many benefits, including higher quality and lower waste. Despite these advantages, there are challenges in execution of these components on projects, due to transportation logistics, skilled labor requirements, and project management techniques. This paper investigates the current landscape of prefabricated pipe spools and potential solutions for minimizing these challenges. The scope of this research includes a proposed workflow, to standardize implementation of these components. Semi-structured interviews were conducted with industry professionals to assess current industry practices and the validity of the proposed workflow. Findings of this paper indicate that greater integration between design, fabrication and transportation is required to minimize inefficiencies when implementing prefabricated pipe spools on projects.

Diabetes is a chronic disease which may lead to other life threatening health complications like heart disease, stroke and peripheral vascular disease that diminished quality of life. In order to assists diabetic patients, we develop a smartphone application to monitor the regular medicine intake and exercise routines through repetitive user friendly and motivational reminders. Health-practitioners including doctors and nurses can frequently view and analyze the daily routine of patients through a web-interface. This paper presents architecture to improve the quality of life with android smart phone as user terminal, and integration of webbased application through web services for health care professionals. We also explain how each of the application interacts with each other and internal integration.

이 연구의 목적은 융합인재교육(STEAM)이 가지는 가치, 필요성, 정당성을 탐색하고, 국내외 사례와 전문가들의 인식을 조사하여 우리나라 실정에 맞는 융합인재교육의 정책 및 실행 방향을 제시하고자 한다. 이 연구의 대상자는 2011학년도 전국의 초.중.고등학교에서 융합인재교육 연구학교의 실무를 담당한 교사 11명과 STEM/STEAM 교육과 관련된 국내 전문가 19명, 국외 전문가 12명이며, 이들이 소속된 기관의 프로그램 운영 사례를 논의의 대상으로 하였다. 우리나라의 융합인재교육 정책에서 고려되어야 할 점을 경험과 이해, 정책적 지원, 추진 방향의 측면에서 분석된 결과는 첫째, 경험과 이해의 측면에서 학교 현장에서 편리하게 적용하고 활동할 수 있는 프로그램 개발과 적용 방안이 제시되어야 하고, 이 교육 활동의 목표가 무엇이며 평가 체제와 환류에 대한 표준이 작성되어야 한다. 전문가들은 주제중심 학습이 가장 선호되는 학습이며, 창의적 사고력 개발과 실생활 적용능력을 위한 교육이 이루어져야 된다고 인식하고 있다. 둘째, 정책적 지원의 측면에서는 우수한 STEAM 교사 양성을 위한 다양한 프로그램과 정책적 유인책이 부족하다. 다양한 시각과 첨단 기술을 가미한 과학기술, 공학 및 예술과 인문사회를 아우를 수 있는 교재를 개발하여 보급하여야 한다. 이를 위해 교사들이 활동한 내용을 서로 나누고 자료를 쉽게 얻을 수 있는 STEAM 네트워크가 필요하다. 이 네트워크에는 기업체, 대학, 연구소 등의 관련 기관이 함께 참여할 수 있도록 정책적인 유도가 필요하다. 셋째, 추진방향의 측면에서는 현행 교육과정에서 STEAM 교육이 자연스럽게 이루어 질 수 있는 정책 방안 제시가 필요하다. 국내외 전문가들은 창의적 사고력을 기르는 교육과 함께 융합적 문제해결력을 기르는 교육 방향으로 나가는 것을 추천하고 있다. STEAM 교육과 관련된 정부의 부처 간의 협조에 의해서 이를 실천해 나갈 것을 요구하고 있다.

National qualification system for SW engineering is intended to be mechanisms to assure the competence of SW professionals. Qualification system for SW engineering can be categorized as national qualification, nationally certified private qualification, and private qualifications. In this paper, we present a summary report of needs analysis for new national qualification systems, based on the survey from human resource department managers of IT companies in IT service, package SW and embedded SW industry. The survey results show that SW qualification system is appropriate for evaluation and career management, but does not provide up-to-date information concerning the technology assessment and change. Based on the result form needs analysis, we suggest the SW specialist and embedded SW specialist as new licenses in national qualification system. In addition, we also propose SW quality management engineer, systems management engineer, IT Protect management engineer, network management engineer and SW architect engineer, as new nationally certified private qualifications.

The contents of a new book currently in preparation are described. The dearth of books in the field of nuclear materials has left both students in nuclear materials classes and professionals in the same field without a resource for the broad fundamentals of this important sub-discipline of nuclear engineering. The new book is devoted entirely to materials problems in the core of light-water reactors, from the pressure vessel into the fuel. Key topics deal with the $UO_2$ fuel, Zircaloy cladding, stainless steel, and of course, water. The restriction to LWR materials does not mean a short monograph; the enormous quantity of experimental and theoretical work over the past 50 years on these materials presents a challenge of culling the most important features and explaining them in the simplest quantitative fashion. Moreover, LWRs will probably be the sole instrument of the return of nuclear energy in electric power production for the next decade or so. By that time, a new book will be needed.
