Online cybercrime has various causes. The criminal guilty language, Criminal lingo is active in the shaded area with the bilateral aspect of the word on cyber. It has been continuously producing massive risk factors in cyberspace. Criminals are shared and disseminated online. It has been linked with fake news and aids to suicide that has recently become an issue. Thus the criminal lingo has become a real danger factor on cyber interface. Recently, Criminal lingo is shared and distributed as cyber hazard information. It is transformed that damaging to the youth and ordinary people through the internet and social networks. In order to take action, it is necessary to construct an expert system based on AI to implement a smart management architecture with block-chain technology. In this paper, we study technically a new smart management architecture which uses artificial intelligence based decision algorithm and block-chain tracking technology to prevent the spread of criminal lingo factors in the evolving cyber world. In addition, through the off-line regular patrol program of police units, we proposed the conversion of online regular patrol program for "cyber harem area".

Mobile patrol robots are mainly used in aerospace and military engineering because they can work at dangerous environment replacing a man. This paper presents a study on the remote monitoring and control system of a mobile patrol robot platform using TCP/IP. The mobile robot consists of intel PXA270 and linux-based system. It can get environment information such as images, temperature, humidity and slope by using two cameras and various sensors. And it transmits information data to a monitoring system through the ad-hoc network which is one of wireless network solutions. At this time, a mobile robot is a server and a monitoring system is a client. Users can monitor environment information which is received from a mobile robot by an application based on PC. We have used TCP/IP protocol, socket programming, interface technique of process and devices and control algorithm to embody the mobile robot and its monitoring system. Experimental results shows that the system can be utilized as a remote patrol monitoring tool.

본 논문에서는, 국방 로봇에 있어 핵심적으로 기술 개발이 요구되는 감시 정찰 분야의 무기 체계 확보를 위한 새로운 구동 메커니즘을 적용한 휴대용 정찰 로봇 개발 방법을 제시하였다. 본 논문은 차륜형 바퀴의 장점과 날개형 바퀴의 장점을 모두 수용하여, 바퀴의 형상이 가변되는 가변형 정찰 로봇이라는 새로운 메커니즘의 제시이다. 특히, 본 논문에서 중점적으로 다루고 있는 순응형 가변구동 정찰로봇은 바퀴의 형상이 노면의 상태에 따라 평지에서는 회전체가 안쪽으로 모여 차륜형의 원형을 이루어 기존의 구동 메커니즘에 비하여 용하고 빠른 이동 능력을 얻을 수 있으며, 험지에서는 별도 구동자의 작용 없이 단순한 구조적 특성으로 회전체가 펼쳐지게 되어 날개 형태로 변형됨으로써 험지 극복능력이 뛰어난 특징이 있다.

While Korea had achieved radical growth of construction industry, it also had accumulated problems in material, human and economical loss due to its low quality of safety level. Therefore, not only enterprises but also the nation is putting in a great deal of efforts for construction safety. However, its effect is not satisfiable. This research aims for change of construction cite by introduction of professional Safety Patrol Management System(SPMS) and consideration of its necessity. To consideration of its necessity, we compared and anaylzed average numbers of indicated dangers and safety accident incidences in each construction cites and we researched changes in worker's safety sense. It will establish the suitable design standards and suggest the basic database for estimating disaster and accident ratio.

The disaster and safety accidents in any construction site occur inevitably. Since the on-site disaster and accident occurrence became one of major concerning factors in construction site, architects & building executers have been flooded with safety management advices. The purpose of this paper is to survey and analyze the effect of the application of Safety Patrol Management System(SPMS) upon the reduction of disaster & accident occurrences in construction site. In order to estimate and reduce the disaster and accident ratio in construction site, various surveyed data has been analysed. It will establish the suitable design standards and suggest the basic database for estimating disaster and accident ratio.

This paper presents a formalized methodology for conducting cost-effectiveness analysis on the ROK Navy's maritime patrol aircraft. The methodology involves a Delphi method application for determining the group of appraisal variables as well as their weight values in the area of aircraft effectiveness analysis, Life-cycle costing was employed to produce cost in terms of present worth values of all costs that occur over the common 20-year life cycle. A wide range of experts was selected so that their opinions could be effectively collected and synthesized to form the framework of the effectiveness model. Such a model development strategy provides easy acceptance of the analysis result and assure fairness of the analysis.

The purpose of this research aimed at performing the easy design. and also the easy on-the-job application or the maintenance interval determination methodology by presenting the determining model or the optimizing maintenance interval in TBM for the preventive maintenance or facility TBM(time-based maintenance) as the preventive maintenance requires the adequate determination or the maintenance interval. The maintenance interval or TBM shall be applied differently for the each interval such as He patrol inspection, maintenance, overhaul inspection. exchange. And it is based on the composition level of equipment. The already informed theories or interval determination methodology for the patrol inspection. repair. and overhaul inspection are difficult for adopting because or the several restriction problems in applying the maintenance schemes as the theory So, the model for determining the optimizing exchange interval or part, maintenance interval of auxiliary machine, unit equipment etc. was presented to apply in the maintenance easily and appropriately.

함정 전투체계의 대공전 기능은 전투함의 생존성을 결정짓는 핵심기능이다. 본 논문에서는 차기고속정 전투체계의 대공전 설계에 있어서 효과적인 개발 방법론으로 모델 기반의 시뮬레이션 기법을 적용하고 있다. 적용된 방법론에서는 대공전 기능이 유한상태기계시스템으로 모델링되고 있으며 모델링 결과로 부터 직접 시뮬레이션을 수행하는 모델기반의 시뮬레이션을 통해 모델의 정확성과 운용의 효과성을 평가하여 설계 시스템을 프로토타입핑하였다. 이러한 결과를 토대로 실제 시스템의 특성을 반영하기 위해 HILS 시뮬레이션을 수행하였으며 최종적으로 구현된 시스템을 완성하였다. 모델기반의 시뮬레이션 기법은 단계적이 반복적인 설계과정을 거치게 됨으로써 개발과정에서 발생할 수 있는 위험요소를 최소화 시킬 수 있기 때문에 고비용 및 고신뢰성이 요구되는 국방분야에서 효과적인 개발방법론으로 적용할 수 있다.
