원자재 가격의 계속된 오름세는 그렇지 않아도 힘겨운 설비건설업계를 더욱 옥죄고 있다. 이번 호에서는 4/4분기 주요 자재 전망과 현장 손익관리 요소에 관하여 소견을 내어 보았다. 현장 손익의 핵심 요소는 인건비, 자재비 관리라고 할 수 있는데, 인건비는 단가가 거의 고정이므로 투입 인원 관리 외에 별도로 고려할 내용이 없지만, 자재는 공사기간 내내 변동성이 크므로 특별한 전략이 필요하다고 생각한다. 먼저 자재 동향부터 살펴 보자.

In the field of network sense for the Ubiquitous environment, the technology of RFID is a significant part. Due to the real time processing of information and the property of network, RFID has been used in service field such as distribution, administrative control of physical distribution, remote measuring device, and security. instead of currently used bar-code. The management system of port facilities using the current RFID technology has the effects of reducing working hours and improvement in data processing, but it is not proper for human resource allocation since it is dominantly worked for physical resources. In this paper, we designed and implemented personnel control system using RFID of 2.4GHz in port facilities which presents a monitoring system for safety operation and increase of efficiency using RFID in order to overcome the limitations and problems of current port operation management techniques.

Quantitative analysis of the number of construction workers and construction period can present a new standard for appropriate personnel. This study presents a Queueing model that predicts the execution time of work procedures, the most important factor among work efficiency indicators. During the working cycle of apartment frame construction the same process tends to be repeated the volume of contruction. Based on these characteristics, this study used a Queueing Model and analyzed reference layer cycle of the delayed frame construction. After adjusting the number of people and the construction period, the performance of the model was analyzed and suggested. This study aims to support the decision making of personnel distribution according to the volume of construction by performing a performance analysis of the Queueing Model.

With the development of digital technology, the marine environment is expected to change rapidly. In the case of autonomous vessels, technology is being developed in many countries, and the international community has begun to discuss ways to operate it. Changes in ships cause changes in the marine traffic environment and urge changes to aids to navigation. This study aims to analyze the cyber security management awareness of VTS personnel to improve the cyber security system for aids to navigation. To this end, the current status of cyber security management was reviewed with a focus on VTS, and a survey was conducted on VTS personnel. The survey analysis used the IPA methodology, and as a result of the analysis, a clear difference was observed in the perception of cybersecurity between those with experience in security and those without experience. In addition, technical measures related to cyber-attack detection and blocking should be implemented with the highest priority. The results of this study can be used as basic data for improving the cyber security management system for aids to navigation.

The purpose of this study is to suggest a improved tact planning and scheduling by reliable Toning of work area in high-rise building construction. To do this, the characteristics of main work including electric & mechanical work were considered through the interview with field work forces. The content of the study is focused mainly on reliable work flow and rhythmical repetition of uniform resource quantity to manage effective tact planning & scheduling. And also the study recommends more implement of tact planning and scheduling to manage human resources successfully in repetitive building construction.

국내 전체 조종사 배출 인원은 연 평균 1,200여명을 훌쩍 넘긴 가운데, 이 중 항공기사용업체를 통해 배출된 조종사 인원은 최근 5년 사이 2~3.5배 이상의 증가추세를 보이며 약 650여명 이상을 배출함으로써 전체 인원의 반 이상을 차지하고 있다. 그러나 현행 법령은 비행훈련과정을 운영하는 대학을 포함하여 항공기사용사업의 업무영역을 고려한 등록 요건 및 안전 고려가 부족하며, 비행훈련은 미래의 조종사를 양성하는 중요한 영역임에도 불구하고 훈련프로그램에 관한 요건이 규정되지 않아 비행안전은 물론, 양질의 조종사 인력양성을 위한 제도적 장치가 부족한 상황이다. 본 연구는 최근 발생한 항공기 사고/준사고 및 안전장애 유형을 토대로 항공기사용사업체에 대해 분석하고, 시행중인 비행훈련에 대한 법과 제도, 안전관련 개선방안에 대해 살펴보고자 한다.

This study aimed at making a way of securing the access by using PCA. We got our result through using Box-Plot and PCA with the access data of the area of security level A~E at K(IPS)center. In order to perform PCA, We confirmed the extracted value of commonality has no problem in performing PCA because VIF is below 2.902. Based on this result, We classified people into Green-list, Blue-list, Red-list, and Black-list in a standard of security level with 1.453, as the eigen value of 1 main element, 1.283, as eigen value of 2 main elementm, 1.142, as the eigen value of 3 main element.
