국내의 건축물의 화재안전성 평가는 화재안전성을 고려한 공간구성, 연기의 유동, 거주자의 피난계획 및 피난성능평가, 건축물 내부에 설치된 방화설비계통의 화재안전성능평가 등을 연구하여 왔다. 그런데 이들 연구의 대부분은 건축물의 공간적 특성분석과 주거여건 등을 고려한 기초자료의 파악 및 분석 등을 국내의 여건과는 상이한 국외의 자료를 근거로 하거나 2차원적인 해석 및 평가에 그치고 있는 경향이 있다. (중략)

Recently, a vessel's maneuvering performance is considered to be an important subject to secure safety at short sea shipping. Especially the high turning performance, which is required to avoid the marine pollution by the ships that was grounded, becomes more severe. In this paper, we discuss the effect of increasing rudder force on turning performance of short sea shipping ship by free running test in towing tank. First of all, we make the 47K PC model ship and high-lift rudder using Coanda effect. And we make the free running test system for the turning test in towing tank. And also we perform the turing test of 47K PC model in several changes of Coanda jet momentum and evaluate the turing performance such as advance and tactical diameter. Finally, we confirm that the increasing of rudder force is very effective to improvement of turning performance of short sea shipping ship.

현재 미국과 유럽, 일본 등에서는 실내 벽 및 천장 마감재에 관하여 성능 기준 설계에 의한 새로운 평가방법이 활발하게 연구되고 있다. 예를 들면 시험에 소요되는 시간과 경비를 절감하고자 Bench-scale test 결과를 이용하여 화재위험성을 예측하는 내장재의 Performance-based fire safety design에 관한 연구가 진행되고 있다. 한편, 성능기준 화재안전 설계를 적용하기 위하여 현재 사용하는 대부분의 존 모델 프로그램은 공간화재시 가연성 마감재의 발화 및 화염확산 및 위험성을 충분히 고려하지 못하고 있다.

Efforts to reduce on-site safety incidents have expanded, leading to active research in this domain. However, a systematic analysis to improve the utility of technology is lacking. In this study, we conducted a survey on the various institutional and technical improvement measures to promote the application of smart construction safety technology over three years after the implementation of the "Smart Safety Equipment Support Project." The results showed that financial constraint was the primary obstacle in the adoption of this innovation. Fostering a flexible environment in the utilization of management fees and financial support of projects was determined to aid in the extensive application of the technology. Ensuring cost efficiency and user-friendliness were principally necessary for technical enhancements in the smart construction safety technology. Technologies, such as VR/AR safety education, real-time location tracking, wearable devices, and innovation on streamlining safety-related work efficiency, had been anticipated to contribute to on-site safety. Operating a smart safety control center was expected to be beneficial in the systematic securing of data and reduction of safety blind spots. Effective methods had been suggested to overcome the barriers that hindered the development and application of smart construction safety technology. This study facilitates in the technological improvements in this field.

The ship's maneuverability is the important factor to avoid ship's collisions. The ship's maneuverability is usually measured in a deep water, and the turning ability is decreased and the course stability is improved in a shallow water. The variation of the turning ability could cause the risk of collision. In this paper, we proposes application technique of Variable Safe-Guard Ring to consider the shallow water effect and to be simple to estimate the grade of collision risk simultaneously. Through the mathematical simulation, the availability of new method was varified. Therefore this method is expected enough to support a maneuver for collision avoidance.
