Maruca vitrata is a main insect pest against crops of Vigna species (V. angularis and V. radiata) and Sesbania sesban in Fabaceae, but the life cycle of the insect is unclear in Korea. In order to know over-wintering possibility, its stage of the insect, over-wintering entry season, and the first adult emergence season of the next year, we investigated over-wintering rates of the insect in outdoor conditions in Suwon ($37^{\circ}16^{\prime}N$ $126^{\circ}59^{\prime}E$ 35ASL). In all colonies which the rearing for larvae, pupae and eggs started after mid-September, adults did not emerge within the year, and all insects died before next June. In several trials for over-wintering of larvae and pupae in soil, all insects died, too. Larvae stored during specified periods at low temperatures (10 and $13^{\circ}C$) did not emerge. From the results, it was postulated that M. vitrata does not have an adaptability to temperature below zero, and cannot over-winter in Suwon area.

Investigation of carabid beetles as on ecological indicator species for wetland characterization and monitoring was conducted in three types of wetlands such as emergent wetland, forested wetland, and estuary, During the investigation period, twenty-eight species belonging to twenty-two genera and three families(Carabidae, Harpalidae, Brachinidae) were identified. The diversity of carabid beetles at riverine wetland such as Woopo (H'=1.18) and Hwapo-neup (H'=1.08) were higher than in the forested wetland (H'=1.03) and estuarine (H'=0.91). Species compositions in each wetland were significantly different(${\chi}^2=1716.8$, P<0.01). Riverine wetlands differed significantly from the forested wetland. Indicator species for the wetland chose with indicator species analysis were reacted sensitively on the parameter such as soil composition, moisture of soil, and environmental change. Thus, it was consequently suggested that these indicator species may be applied for wetland characterization and monitoring of the wetland ecosystem.

The developmental process of Paracolopha morrisoni's galls on Zelkova serrata until the emergence of alatae from the galls was studied at Chonju, Korea. The galls were formed from late April to early May, 1997 and the galls began to open in early June. The length and width of galls and leaves were measured during the period from gall formation to opening. The length and width of galls have been increased until mid May continuously. The galls stopped growing at 12th of May. Fundatrices (the first generation in the gall) began to larviposit from May 15th and the second generation developed in late May. The alatae of the second generation arrived at the final stadium, that was escaped from the gall, in early June. Thus, there were only 2 generations in the gall. The close correlationship between gall growth and leaf growth suggests that leaf growth force may have a great influence on gall development.

Pine wilt disease caused by pine wood nematode, Bursaphelenchus xylophilus (Steiner et Buhrer) Nickle, has become the most serious threat to pine trees in Korea since 1988. Pine wood nematode is transferred to healthy trees by Monochamus alternatus (Coleoptera: Cerambycidae) during its maturation feeding and female oviposition. A typical control method against insect vectors in Korea is fumigation of the dead trees by using metam-sodium SL (25%). However, this method is not environment friendly because of the forest contamination by chemical application and destroying landscape by plastic cover. Portable Bark Remover (PBR) was invented to reduce these environmental problems. The vectors oviposit under the bark of the newly dead trees only. Debarking infested trees prevents the vectors from laying eggs and eventually, they can not complete their life cycle. The PBR is a modified debarking device that is attached on the top of the electrical chain saw, which allows ease and rapid debarking of the infested trees. The new method by PBR is expected to be more economic and effective than other conventional methods such as "crushing", "burning" and "fumigation".

As foreign immigrants are rapidly increasing, how they without previous knowledge and experience adjust themselves to local circumstances where they come to live becomes a major social issue. In order to analyze their adjustment process, this paper suggests a model which consists of relationships with local environment and people on the one hand, and of geographical knowledge and imagination on the other. The analysis of questionnaire survey based on the conceptual model suggests some findings. As there are considerable differences in the extent of their local adjustment and felt difficulties among immigration types, nationalities, and dwelling regions, foreign immigrants‘ policies should be devised proper for their type and characters.

Monochoria vaginalis var. plantaginea (Pontederiaceae) is one of the most problematic weed in the rice field in Korea. Tanysphyrus (Tanysphyroides) major was selected as a potential biological control agent for M. vaginalis. Continuous rearing of T. (T.) major was carried out from 2006 to 2007, and its morphological characteristics and ecological characteristics were investigated. This species has a single generation per year, over-wintering as an adult stage. The emergence of adults starts in later June and last until September. These observations indicate that T. (T.) major takes $22{\pm}0.7$ days to develop from egg to adulthood. Host specificity test showed that finally selected this species was suitable candidates for the biological control of M. vaginalis var. plantaginea since it showed negative host specificity against major 60 test crops.

식생전이에 따른 기간분리는 해외 및 국내 논문에서 식생영향을 받지 않는 곡선식과의 차이를 검토하고, 측정성과별 분류를 통해 곡선식을 개발하는 방법이 제시하고 있으나 적용기간 설정에 대한 구체적인 방법이 없다. 또한 상하류 비교를 통해 기간분리의 적정성을 검토할 수 있다고 명시되어 있으나 비교 관측소가 없는 경우 검토에 어려움이 있다. 본 연구는 2017년 수위-유량관계곡선식의 적용시간 결정에서 현장 식생모니터링 자료와 함께 연간 수온변화를 참고 자료로 활용하였다. 연간 수온자료를 산정하기 위해 측정된 수온과 해당 기온에 대한 상관관계식을 개발하였다. 또한 산포가 발생하는 측정성과는 생성된 연간 수온자료를 참고하여 전이여부를 판단하였다. 2018년은 2017년의 계절별 수온변화 자료 및 수집된 주요 수중식생의 생활사를 참고하여 연간 측정계획에 활용하였으며, 수위-유량관계곡선식 개발 시 동일한 방법을 사용하였다. 2017년은 가뭄으로 인해 수중식생에 의한 전이가 활발했던 기간으로 측정성과에 대해 식생영향 최고 기간과 최대 기간의 동일수위에 대해서 유량을 비교한 결과 $0.003m^3/s{\sim}1.099m^3/s$의 범위를 보였다. 유출량 비교의 경우 기간분리를 적용하지 않았을 경우 약 40.1% 과대 산정되었다. 2018년은 잦은 강우로 인해 수중식생의 이탈 및 전이 영향수위의 발생빈도가 비교적 적어 동 수위 유량을 비교한 결과 $0.19m^3/s{\sim}0.49m^3/s$의 범위를 보였다. 연 유출량을 비교한 결과, 기간분리를 고려하지 않은 경우가 약 39.6%로 과소 산정되었다. 따라서 본 연구사례를 통해 식생에 의한 기간분리가 발생하는 지점에 대해서 비교적 합리적인 측정주기 계획을 위한 확립 근거와 기간분리 적용기간에 대한 합리적인 자료로 활용 될 수 있을 것이다.

This study aims to understand the community sense and need for community programs for large scale cooperative rental housing residents, and to set the direction of the construction plan. To this end, a survey was conducted on visitors and contractors of the model house in Westaybyeolnae. As a result of the analysis, the most visitors to the model house were in their 20s and 30s, while the number of contractors in their 30s was the most. Most of the model house visitors currently do not participate in community activities, but the contractors wanted to interact with neighbors about once a week. The contractors had high demands for sports facilities and child-rearing facilities, and the most demanded for living cooperatives and child care services. However, the range of neighbors required by age, the degree of meeting, common facilities and programs required were different.
