The paper presents the incidence rates of malignant tumors of the central nervous system assessed by the component analysis. The data on primary registered cases of malignant tumors of the central nervous system in the country were used as the material of the study for the period from 2004 to 2011. A general trend of increase in the number of patients with malignant tumors of the central nervous system in Kazakhstan was determined and the potential of their increase was evaluated, which can be due to changes in the morbidity risk and age specifics, as well as the increase in population.

Today, Korean Disaster Control System has better change the existed it for substantial prevention and the emergency control system. And it requires the new National Wide Disaster Control System through building up the cooperation system with related posts which are scattered over the National Administration and one-way management for disaster affairs by them. Therefore 119 that might have a lot of technical knowhow should be a center of disaster affairs which will be able to take all rescue, relief(first aid), fire fighting, and preventive affairs. Then it could be a service organization of citizen. Consequently, it will strengthen National Disaster Control ability and it could be a National Wide Disaster Organization which is ready for prevention, preparation, confrontation of all kinds of disasters with absolute reliance by the citizen.

This study was to suggest the necessity of depth research in order to enhance the effectiveness of technical consulting system. And the purpose of this study was to decrease the construction accidents to some extent, being on the increase day by day as it takes issue properly and suggest a reform measure. As for research method, it executed the collection of public opinions widely and questionnaire with the bibliography, expert of construction safety, the related institutions, academic world, safety association, and director of construction site. Also, it was to suggest the reform measure by the stage, classifying the problems on the system and operation by 4 stages like a stage of delivery of subscription and supervision, a stage of contract with guidance of technology, a stage of executing the guidance work of technology, and a stage of performance of advice.

This paper reviews the one of problems that may occure for the tram operating in Korea, it's a free-riding problem, I analyzed the feasibility of combining the introduction of world-class technology solution "IT". It is under review the introduction of tram in Su-won city, Chang-won city, Wi-Rye new town. Free-riding is one of the biggest issues of any agency that operates the public transportation system. It has been acting as the main factors threatening the financial integrity of the operating agency, and the ratio of free-riding is further increased. In this paper, I want to build a foundation for the development of the system by analyzing the economic feasibility for the introduction of free-riding prevention system.

In construction industry, workers' accident rates are relatively high compared to those of other industries. These high accidents rates are mostly due to the characteristics of construction process. In order to effectively reduce the accident rates, it is required to develop not only immediate measures but also long-term programs of instruction, training, and education. In addition, well-analyzed information on past history is required for the prevention of accidents. By examining about 800 cases of construction accidents that happened between Jan. 1992 and Dec. 2000, this paper developed an information system that provides appropriated safety information to the construction workers. This system is expected to contribute to the workers' safety in construction industry.

장시간 컴퓨터나 스마트폰을 사용하는 사람들에게서 손목터널증후군(Carpal Tunnel Syndrome)의 발생 가능성이 높아지며, 이를 방지하기 위해서는 꾸준한 손목 스트레칭과 위험성의 모니터링을 통한 사용자 피드백이 중요하다. 본 연구에서는 사용자 스스로가 손목 터널 증후군의 위험성을 인지하고, 손목 스트레칭 할 수 있도록 손목 터널 증후군 예방 시스템(Carpal Tunnel Syndrome Prevention System, CTSPS)을 구현하였다. 전체 시스템은 하드웨어와 소프트웨어로 구성되며, 소프트웨어는 사용자가 설정한 사용 시간과 잠금 시간을 바탕으로 알림 및 잠금을 수행한다. 이때 사용자는 아두이노와 가속도 센서를 이용하여 손목 스트레칭 할 수 있으며, 사용 패턴을 분석하여 사용자에게 맞는 생활 가이드를 제공할 수 있다. 구현된 시스템을 평가하기 위해 피실험자 5명을 대상으로 3일간 스마트폰 사용 시간 및 터치 횟수를 측정하였고, 설문조사를 수행한 결과 스마트폰의 사용 빈도가 줄었으며, 통증 완화 등 긍정적인 효과를 확인할 수 있었다.

When a fire is detected by a sensor of a fire detector, the fire is notified to the manager through the siren. However, if the manager is not indoors, prompt action may not be taken in the event of a fire. In this study, we would like to propose a platform system for fire prevention applying IoT to prevent problems that arise when building manager is absent. This paper presents the structure and operation principle of fire prevention platform system design using IoT, describes the overall system design through fire detector H/W design, micom S/W design and Android application development, and is expected to develop a system that can respond a little faster in case of fire.

As cyber attacks become more intelligent, there is difficulty in detecting advanced attacks in various fields such as industry, defense, and medical care. IPS (Intrusion Prevention System), etc., but the need for centralized integrated management of each security system is increasing. In this paper, we collect big data for intrusion detection and build an intrusion detection platform using deep learning and CNN (Convolutional Neural Networks). In this paper, we design an intelligent big data platform that collects data by observing and analyzing user visit logs and linking with big data. We want to collect big data for intrusion detection and build an intrusion detection platform based on CNN model. In this study, we evaluated the performance of the Intrusion Detection System (IDS) using the KDD99 dataset developed by DARPA in 1998, and the actual attack categories were tested with KDD99's DoS, U2R, and R2L using four probing methods.

In Korea Water Resources Corporation (K-Water) has seen four problems rising in four aspects of property management of approximately 1,300 buildings scattered through put to country. To solve these, ground data for repair and replacement works to be conducted for prevention will be prepared and building maintenance system (hereinafter referred to as PBMS) intended to record related repair and replacement work histories and calculate LCC of the related these items will be developed. PBMS, a web-based system, will be developed for users' convenience and data monitoring in real time. To sum up, PBMS are expected to maximize efficiency in four aspects including the establishment of repair and replacement work plans for prevention, history management, DB for predicting future work to be occurred and enable the determination of priorities by being developing into facility condition assessment systems through the results of analysis of repair and replacement histories and LCC.

This paper proposes an inter-floor noise prevention system using an open-source controller. In the proposed system, Arduino which is a widely used open source controller analyzes sound signals and vibration signals with fast fourier transform. When the magnitude of the band-passed signal excesses the noise reference considering transmission loss of a panel or a wall, the system displays warning messages on an LCD module and a mobile device for users to be aware of the noise condition. In the experiment, the system has succeeded extracting and processing the band-passed signals between 130 Hz ~ 1040 Hz. When the magnitude of the extracted signal that is subtracted from the transmission loss exceeds 45 dB, the system has displayed the warning message on an LCD module and a mobile devicefor noise reduction.
