Distribution and abundance of species are influenced by their environmental condition. Among various environmental factors, a vegetation is one of the most influential factors, because it is used as habitats as well as food resources. Arthropods including insects play a important role in forest ecosystems as grazers, scavenger, predators, etc. Deciduous and coniferous forests have different plant community composition, resulting in different environmental condition. In this study, we collected arthropod communities at two different deciduous and coniferous forest stands in the Mountain Gariwang. At each stand, three different sampling methods were used: soil core for soil macroinvertebrate, pitfall trap for wandering insects, and sweeping net for insects in the shrups. Therefore, sampling was conducted at vertical habitats in the forest. The results showed that there were no difference in the number of orders from soil at both coniferous and deciduous stands. However, the abundance was higher at coniferous stand than at deciduous stand. Collembola was the dominant taxa in soil. Meanwhile, there were no statistically significant differences of community composition between coniferous stand and deciduous stands. Multivariate analyses was conducted to characterize differences of communities at different stands as well as vertical distribution in forest.

Along with development of medical science, stroke is showing an increasing trend of occurrence due to improvement in living standards and increase in aged population. In particular, about 56% of all stroke patients are suffering from hemiplegia, which bring difficulty in everyday activities. There are various means of rehabilitation for such hemiplegic stroke patients, but such methods cannot be carried out alone but must be accompanied by therapists. Patients must visit treatment facilities to receive treatment. Accordingly, under the consideration that treatment and rehabilitation of stroke can be assisted using functional game as an auxiliary means to continued counseling and treatment by physician without limitation on location, time, and cost, the purpose of this study is to propose a rehabilitation rhythm game based on motions using appropriate platforms such as PC and smart phones.

We have accomplished a various reaction experiment for a purifying agent selection which is related with efficient site demobilization about soil contaminated with the total petroleum hydrocarbon(TPH) in link of contaminated soil purification enterprise of power train center in Y railway car places of business for an oxidizer comparison experiment, we have differed consistency and implantation quantity of the hydrogen peroxide (H2O2). The result showed the highest 98.8% removal ratio, when H2O2 is 35% consistency. In the same way, the result which implants at 1:1 ratio (hydrogen peroxide (H2O2) : the catalyst (FeSO4 ․7H2O)) showed a similar result, when only the hydrogen peroxide was implanted.

이 연구는 사유림 기능평가에 적합한 산림기능 유형 및 기능 우선순위를 분석하기 위해 수행되었다. 전문가그룹과 시군산림공무원을 대상으로 설문조사를 실시하여 제안한 산림기능유형의 적정성과 산림기 능의 우선순위를 평가하였다. 현행 산림기능유형에 대한 기능명칭 변경, 통합의 필요성에 대해서 전반적 으로 동의하는 것으로 나타났으며, 최종적으로 4개의 산림기능(자원순환, 수자원함양, 생활환경보전, 산 림보전) 구분체계를 제시하였다. 또한 산림기능 우선순위는 집단간, 권역별 우선순위에 차이가 존재하므 로 전국 사유림 기능평가시 국공유림처럼 획일적으로 기능 우선순위를 부여하는 것보다는 권역단위로 기능 우선순위를 상이하게 적용할 필요성이 있는 것으로 판단된다.

We've collected litter-dwelling predatory arthropods (spiders and carabid beetles) by using pitfall traps at four different fire intensity treatment areas (control, ground fire, canopy fire, and canopy fire with plantation) at four different regional areas in 2005. We analyzed the arthropod community structures with PC-Ord for the difference of arthropod community among the various fire intensity treatments and control. Our objective was to verify if there was any difference between fired areas and non fired area (control) and between canopy fire with plantation and canopy fire without plantation. From our arthropod community structures, we found there was distinct community composition difference between fired areas and non-fired area as well as between control and canopy fire treatment with plantation or non-plantation. However, we are not sure yet that there was any distinct difference between control and ground fire treatments. Our results from the multivariate analysis, Non-parametric Multidimensional Scaling ordination, could be relatively conclude that the main difference of arthropod community between fired areas and non-fired areal and canopy fire with plantation or non-plantation was caused from the difference of arthropod habitat pattern such as litter depth, litter volumem, CWD cover or volume, and et. al. When we compared to control and other treatments, we could also conclude that the canopy fire treatment with non-plantation was relatively closed to control than the canopy fire treatment with plantation.

선박에 싣기 위하여 컨테이너 장치장에서 반출하는 컨테이너 상단에 다른 컨테이너들이 장치되어 있다면 위의 컨테이너들을 임시 로 옮기는 작업이 필요한데 이런 작업을 재취급이라 하며, 이로 인하여 장치장의 생산성은 떨어지게 된다. 장치장에서 반출 작업을 수행할 때 재취급 작업을 하지 않도록 하기 위하여, 적하 계획이 수립된 후 선박이 도착하기 전까지의 유휴 시간을 이용하여 컨테이너들을 미리 정리하는 작업을 재정돈 작업이라고 한다. 보통의 경우 베이내의 이동만으로 재정돈 작업 계획을 수립하는데, 컨테이너가 장치된 상태에 따라 너무 많은 시간을 사용한 후 결국 해를 구하지 못하는 경우가 발생한다. 본 논문에서는 이웃한 베이의 상단을 임시 저장 공간으로 활용하여 재정돈 작업 계획을 수립할 수 있는 방안을 제안한다. 이 방안이 복잡한 장치상태에서도 허용된 시간 내에 작업 계획을 수립할 수 있다는 것을 보이기 위하 여, 수치실험을 통해 제안한 방안의 성능을 평가하였다. 다양한 베이를 대상으로 실험한 결과 복잡한 베이에 대하여 허용된 시간 내에 유효하 고 효율적인 계획을 수립할 수 있음을 확인하였다.

Korea is worldwide top manufacturer of offshore plant industry, while shown weakness in high-valued offshore plant service industry (OPSI). The governmental support policies and studies for fostering programs are centered on shipbuilding and engineering sector. On the other hand, offshore logistics service sector among the programs is neither included as governmental fostering support sectors nor ever-studied. Domestic shipping and logistics companies have many experience of handling various project, heavy-lift cargo and even super blocks on shipbuilding industry. However they are faced with lack of appropriate heavy carrier and others. So for their successful entering into offshore plant logistics market, systematic preparation, studies and supporting policies are highly recommended.
