본 연구의 목적은 국토교통부로부터 위탁받아 한국시설안전공단에서 운영하고 있는 건설사고조사위원회 사무국에서 '15년부터 축적한 총 90건의 건설현장사고를 대상으로 공종별 위험요소 및 재발방지대책을 key word 행태로 발굴하여 유사한 원인으로 재발되는 건설현장사고를 방지하는 자료로 활용하고자 수행하였다. 본 연구에 활용한 건설사고 모집단은 건설사고 전체를 대표하기는 어려우나 일정 규모 이상의 건설사고에 대한 분석 자료로 통계적 가치가 있는 것으로 사료되며, 향후 보다 신뢰성있는 분석을 통한 피드백을 위해서는 효과적으로 건설사고정보를 수집할 수 있는 제도개선이 필요한 것으로 판단된다. 금번 분석된 내용은 현장에서 건설안전 확보를 위한 기초자료로 활용이 가능할 것으로 생각되며, 향후 건설안전정책 방향설정의 자료로도 활용될 수 있을 것으로 기대한다.

Objective: To explore the clinical effects of nimotuzumab combined with chemotherapy in the treatment of late gastric cancer. Methods: A total of 34 reoccurrence or metastatic patients with late stage gastric cancer who were confirmed by histopathology and/or cytology were selected and randomly divided into observational and control groups, of 17 cases each. Patients in the control group were treated with the standard DCF plan, while patients in observational group additionally received nimotuzumab. The short-term and long-term efficacy and adverse reactions in the 2 groups were followed. Results: The objective response rate (ORR) and disease control rate (DCR) were 64.7% (11/17) and 82.4% (14/17) in observational group and 25.0%(4/16) and 37.5%(6/16) in the control group(ORR and DCR between 2 groups, ${\chi}^2=5.2412$, P=0.0221 and ${\chi}^2=6.9453$, P=0.0084). The median progression-free survival (PFS) time and median overall survival (OS) time were 6.50 months and 12.50 months in observational group and 4.50 months and 8.25 months in the control group (P=0.0212; P=0.0255). The main toxic and side effects in the 2 groups were reduced leukocytes and hemoglobin, gastrointestinal reactions and hair loss and these were relieved after symptomatic treatment and nutrition support therapy. There were no differences in the occurrence of toxic and side effects between the 2 groups. Conclusions: Nimotuzumab combined with DCF plan is effective in treating late stage gastric cancer. A larger scale study is now warranted for confirmation of the findings.

It is very difficult to control the expansion of reed at a wetland ecological park due to their aggressive reproduction capability. Therefore, proper topography and wetland hydrology should be provided before the construction of a wetland ecological park. Appropriate measures should be taken at the initial stages to prevent reed expansion. Field experiments were conducted at the newly constructed wetland ecological park for 15 months to develop methods to control the reproduction and expansion of Phragmites communis. A complete shading method had the best effect on the prevention of reed reoccurrence among other methods. Complete removal of the rhizomes controlled the reed growth to a greater extent than cutting the aboveground shoots. Water-level manipulation was also better than a half-shading method for the prevention of reed reproduction. These results indicated that soil properties and edge effects can influence the reed growth. Cutting only the aboveground shoots facilitates the growth of reed. These results suggest that reed control should be implemented repeatedly and an alteration in the wetland topography and hydrology may be more effective in the long term. Combination of treatments such as water-level management with shading should be considered to control the growth of reed. Adoptive management for created or restored ecosystem might be considered for accomplishment of its original purpose.
