  • 기존의 경로계획 방법은 최단거리의 경로를 생성하는 것에 목적을 둔다. 그러나 이렇게 선택된 최적의 경로가 안전한 주행을 보장해주지는 못하는데, 이는 종종 좁은 통로나 이동 장애물이 많은 영역으로 경로를 생성하기 때문이다. 그러므로 로봇은 정보 격자지도를 이용하여 안전하게 이동할 수 있는 경로를 생성하는 것이 필요하다. 이 정보 격자지도는 기존의 지도가 가지고 있는 영역의 정보 외에 유도지역과 위험지역을 포함한다. 안전한 경로는 인력과 척력을 이용하여 위험지역을 우회하고 유도지역으로 접근되어 생성된다. 실험 및 시뮬레이션은 제안된 방법이 안전한 영역으로 경로를 생성시켜, 안전하게 주행하는 데 유용하다는 것을 보여준다.

  • Purpose : To provide basic data for establishing the policy of safe handling of cytotoxic drugs and for building training materials and clinical guidelines for nurses handling cytotoxic drugs. Methods: 255 nurses in Seoul and 257 nurses in D metropolitan area participated in the study. Questionnaires were based on the safe handling guideline for cytotoxic drugs issued by OSHA and ONA. Results: Nurses in Seoul scored higher in the cognition for safe handling guidelines of cytotoxic drugs in preparation, administration. as well as total score compared with nurses in D metropolitan area. The practical score also showed higher in nurses in Seoul in administration, disposal and total score. But both groups showed low level of practical score. The answers why they could not follow the guideline for cytotoxic drugs were "don't have", "busy", and "don't know", etc Conclusion: Handling of the cytotoxic drug is very common and important. The study findings suggest that hospitals especially in D metropolitan area should educate the nurses and supply equipments for safe handling of cytotoxic drugs. Thus, repetitive and continual education of all nurses including experts is needed. In addition, it is necessary to supply enough protective equipment for preventing exposure to the cytotoxic drugs.

  • Ship owners now demand a new design approach for the rudder that considers detailed design information such as maneuverability and environmental loads etc. on a quantified basis. In this paper, we developed the concept of a safe operation capability chart for the design of a rudder area. The chart can be used as the basis of design considering the maneuverability and environmental loads. To confirm the applicability of the safe operation capability chart for use as the basis of design, four different rudders are assumed in this work. First, it is determined whether or not it is appropriate to design a rudder by applying a conventional design approach based on IMO maneuvering tests. The proposed concept is reviewed for use as the basis of the design by investigating the effect of rudder area on capability charts that are plotted according to the rudder under various environmental conditions.

  • There is an increasing interest in and efforts for safe residential environment from crimes nationwide. Many cities are making efforts to create safe residential environment by enacting ordinances and guidances on safe design for preventing crimes and implementing demonstration projects. In line with the trends of the times toward 'improvement of living conditions' through urban regeneration, the importance of the Crime Prevention Through Environmental Design(CPTED) has recently emerged in the field of residential housing regeneration. Indeed, the CPTED is included as essential factor in the recent deteriorated residential area regeneration related projects. In this respect, the purpose of this study is to provide the basic data on the methodology of CPTED to be applied to the regeneration of deteriorated residential area in the future. To this end, this study selected three representative CPTED projects in Busan - 'Deokpo-dong Hope and Stepping Stone Village,' 'Chilsan-dong CPTED Happiness Village' and 'Sujeong-dong Crime Prevention and Safe Village' as objects of this study and then investigated and analyzed project contents, application of CPTED strategy, subjects who are implementing projects, and the time when they implement projects as the framework of my analysis. The findings from this study are as follows: First, the projects that were largely based on hardware should be improved by including software in the future. Second, the current Step 2 should expand into Step 3 Maintenance in applying CPTED strategy. Third, it is necessary to encourage exchange and cooperation between unit projects and subjects who are operating related projects.

  • As more than 90% of global trade is carried by sea there is little doubt that the safety of the ports at which the world's trading fleet call is of critical concern. The concept of 'safe port' continues to be an area of critical concern for charterers and ship-owners. In light of increased global security and health risks the recognised principles are under security. This paper examines the nature of safe port, and analyses the precedent trend of safe port and its Implication

  • Background Little is known concerning hair diameter variation within the safe donor area for hair transplantation surgery. Thicker or thinner hair may be needed, depending on the recipient area, hairline design, and the purpose of surgery. Methods Twenty-seven patients (7 men and 20 women; mean age, 28 years; range, 20-47 years) were included in this study. The midoccipital point was used as the reference point on the horizontal plane at the upper border of the helical rim. The target area width was 15 cm (7.5 cm to the right and left of the reference point) and the height was 8 cm (2 cm above and 6 cm below the reference point). The study area was divided horizontally into 3 5-cm sections (A, B, C) and vertically into 4 2-cm sections (1-4), creating a total of 12 zones. Ten anagen hairs were randomly obtained from each zone and their diameters were measured. Results Hair diameter in the 4 vertical sections varied significantly, gradually decreasing from sections 1 (superior) to 4 (inferior) in all 3 horizontal sections (A, B, and C). Conclusions Our results suggest that sections 1 and 2 of the occipital safe donor area would be useful for obtaining thicker hair, such as in procedures to treat male- and female-pattern hair loss, whereas hair from zones 3 and 4 could be useful for transplantation surgery requiring thinner hair, such as eyebrows, eyelashes, and female hairline correction. Our results may be clinically valuable for planning hair transplant surgery and choosing the optimal donor region.

  • The purpose of this study was to find out more effective schemes on safe water supply in rural area. Then, this study was carried out to investigate drinking water qualities of 20 simple piped water supply systems and 20 water pumps in Chun Sung County, Kang Won Province from 12th December to 24th December, 1983 and was compared this results with the previous results that had been carried out at the same sample sites from 1st July to 30th August, 1981. 1. This results of water quality in winter are better than the previous results in summer because this results are identified as safe 20%, unsafe 35% in simple piped water supply systems, safe 50%, unsafe 20% in water pumps and the previous results are identified as safe 1.8%, unsafe 78.6% in simple piped water supply systems, safe 5.5%, unsafe 73.6% in water pumps. 2. Water qualities of water pumps are better than that of simple piped water supply systems because the former is identified as safe 50%, unsafe 20% and the latter is identified as safe 20%, unsafe 35%. 3. Drinking waters that are in need of chlorination in winter as well as summer are 45% of simple piped water supply systems and 30% of water pumps.

  • 선박의 충돌회피 방법을 제시하는 관점에 있어, 두 선박의 조우각도에 따른 속력이 충분히 고려되어야 할 것이다. 하지만 선박의 충돌회피를 위해 새롭게 연구된 근접상황 선박충돌회피지원 모델의 Safe-Guard Ring 설정은 본선과 상대선박의 속력비가 약 1.7 이하로 제한되어 있으므로 제한된 범위 이외의 경우에서 충돌 위험이 존재 할 수 있다. 따라서 본 연구에서는 두 선박이 조우하는 각도 및 속력을 고려한 Safe-Guard Ring 설정을 연구함으로써 안전한 충돌회피 조종을 위한 선박충돌회피모델을 제시하고자 한다.
