The information of the IT convergence has extended through the whole business ares with supplying intelligence terminal such as smart phone and the technology of sensors and wireless networks. And also, the existed industry became to high technology and extended various parts. The industry of the elevator became the center of the life offering the diversification of the user environment access and high building control. In this paper, we suggest the elevator control system integrated wire and wireless based on Information technology. We suggest the service model of user friendly connected by internet. For this, we make the relation model of the elevator system and IT environments and then design the service model for wire service and wireless service using smart phone. It can make to supply efficient information with wire and wireless environments and also make improvement in accessability for the disabled peoples.

In this study, we contemplated types, essence, characteristics of text data which is material for visual expression of text visualization part of data visualization research and also analysed the multidirectional means of expressive approach for it. Studies of text visualization are spread dramastically under the influence of computer development, open data, wide use of visualization tools, etc. For these reasons, text visualization works have been creating as art works or output of research through various inter-discipline convergent research with engineering, art, humanities, sociology, etc. Nevertheless the theoretical studies on text data itself and its visualization, and also systematic analysis of its approach are rarely made. Data is target of understanding and interpretation, and it has infinite information and possibility with process and approach for it. Considering the attainable status of data in future human society, text visualization which is convergent academic field of study starting with understanding and interpretation of data needs further methodological research and theoretical accumulate.

본 논문은 혼합현실(Mixed reality) 에 대한 새로운 접근법을 제시한다. 혼합현실은 실제환경 (Real environment)과 가상환경 (Virtual environment) 이 융합된 가상현실로서 기존의 혼합현실 연구자들은 두 환경을 가능한 정확하게 정합(Registration)시키고자 노력하였다. 이러한 노력은 때때로 복잡한 계산과정이나 부가적인 장치를 요하기도 한다. 부가적인 장치의 사용은 사용성문제를 유발할 뿐만 아니라 추가적인 비용도 요구한다. 우리가 제시하는 접근법은 이러한 노력들과는 반대로 많은 부분을 사용자의 인지력과 상상력에 의지한다. 즉, 사용자의 인지력으로 두 환경 간의 오차를 보정하며 심지어는 사용자에 의해 두 환경 간의 결합이 머릿속에서 이루어진다. 우리는 이러한 접근 방법을 Loosely Coupled Mixed Reality(LMR)라고 부른다. 본 논문에서는 혼합현실에 대한 새로운 접근법인 LMR에 대해 설명하고 LMR이 갖는 여러 가지 쟁점을 짚어보았다. 또한 LMR의 효과를 검증하기 위해 만든 골프 게임을 설명 하도록 하겠다.

Information system development projects are increasingly enlarging in size and are becoming more complex in the development environment. The traditional approaches for the development of information system, however, haven't shown the expected performances in the management for them and many researchers have been trying to find a new approach for overcoming this challenges. And one of the new approaches is the PMO and it is introduced to solve the problems of project management and the related organizational, technical, and administrative problems. This study attempted to find the efficient information system establishment plan. In particular, this study wants to research the practicality of PMO and the detailed utilization plans. As a result, this study proposes the structure of project implementation, the requirements, the direction of the basic system design, the scope of system development, and the budgeting for the systems. It is expected to contribute the successful implementation of the project.

최근 IT기술의 발전으로 인해 클라우드 컴퓨팅 기술이 도래됨과 동시에 다양한 분야에서 클라우드 컴퓨팅 기술을 융합하기 위한 연구가 진행되고 있다. 그 일환으로 데이터센터에도 클라우드 컴퓨팅 기술을 접목시켜 사용되고 있는 추세이다. 클라우드 데이터센터는 다양한 사용자들이 각기 다른 디바이스를 기반으로 데이터센터에 접근하여 저장된 데이터를 사용하여 업무를 수행하게 되며, 다양한 환경에서 사용자들이 동시다발적으로 저장된 데이터에 접근하게 된다. 클라우드 데이터센터는 시 공간에 관계없이 접근 가능하기 때문에 사용자의 상황이 자주 변경되며, 이에 따라 무분별한 데이터의 접근으로 인해 다양한 보안 위협이 발생할 수 있다. 본 논문에서는 이러한 보안 위협을 예방하기 위해 사용자의 상황을 인지하고, 그 상황에 따라 접근 여부를 결정하는 상황 인식 기반의 접근제어 모델을 제안한다.

This is a descriptive study on what factors influence the quality of life of early and late middle-aged men. This research is the secondary analysis which was conducted with the data of 170 people and the primary data from 2017 by using SPSS/WIN program. The results show that the main factor is depression in early middle-aged men and social support for late middle-aged men, whose overall ability to explain was 77.8% and 64.7%, respectively. Therefore, this research suggests that multidisciplinary and converged approaches-developing nursing intervention programs based on the factors shown in this paper, creating social environment, strengthening social supportive system and making policies-be required for the enhancement of middle-aged men's quality of life.

This study introduces integrated approach on detection of a leakage in a sea wall based on remote sensing, electric resistivity survey, electromagnetic survey, and borehole survey for the Seosan A-Region sea wall. The satellite temperature distribution from Landsat ETM+ data identifies water leakage distribution and period by analyzing temperature mixing patterns between sea water and fresh water. Electric resistivity survey provides both horizontal and vertical anomaly distributions over the sea wall showing below average electric resistivity. Electromagnetic survey(electrical conductivity survey) reveals the potential possible leakage areas with minimal background impact by comparing electrical conductivity values between high and low tides. Borehole image processing system confirmed the locations of anomalies identified from the other survey methods and distributions of vertical fracture zones. The integrated approach identified 41.7% of the sea wall being the most probable area vulnerable to water leakage and effectively approximated both horizontal and vertical distribution of water leakage. The integrated analysis of remote sensing, electric resistivity survey, electromagnetic survey and borehole survey is considered to be an optimal method in identifying water leakage distribution, period, and extent of fractures knowledged from the boreholes.

The purpose of this study is to investigate the relationship between the degree of clinical practice satisfaction and professional self concept of health administration students. A total of 250 structured questionnaires were analyzed using the SPSS Ver.24.0 program for students from 10 universities nationwide. As a result of the study, the students of health administration major showed the satisfaction level of clinical practice and the level of professional self concept more than average. Clinical practice satisfaction and professional self concept were positively correlated with each other. The variables that have the most significant effect on clinical practice satisfaction were professional practice in the detail of professional self concept. Therefore, in order to improve the satisfaction of clinical practice and professional self concept of students in health administration, it is necessary to thoroughly check the training site before practical training, to consult with preliminary practical guidance professor, to develop clinical practice program and to find a system of mutual cooperation system with clinical training institution need.

Network Access Control System that is one of the efforts to protect the information of internal applies to effectively control of insider and automatic network management and security. However, it has some problems : spoofing the authorized PC or mobile devices, connect to the internal network using a system that authorized users are away. In addition, information leakage due to malicious code in the same system. So in this paper, Network 2-Factor Access Control System based on RFID security control system is proposed for safety communication environment that performing a two-factor authentication using authorized user and devices to connect to the internal network.
