강우유출수의 오염기원별 기여도를 파악하고자 홍제천 유역의 구기 배수분구를 대상으로 강우시 유량 및 오염물질 발생경향 및 오염기원별 오염도 분석 등에 대하여 살펴보았다. 강우시 발생초기의 오염물질의 농도는 강우에 의한 초기세척현상(First Flush)에 의해 상당히 높게 나타났으며, 강우초기의 높은 오염물질의 농도는 강우에 의해 희석되어 일시적으로 낮아졌다가 높은 강우강도에 의하여 급격히 상승하였으며, 이후 오염물질의 농도는 유량의 감소에 따라 점차적으로 감소하는 것으로 나타났다. 물질수지식을 이용한 근사적인 오염부하의 오염원별 기여도 분석에서 관거 퇴적물에 의한 오염도가 COD $27.7\%$, SS $47.5\%$로 나타났으며 지역에 따라서는 건기 하수보다도 더 높은 기여도를 보이고 있어 월류수 오염부하의 제어측면에서 정기적인 관거내 퇴적물의 준설과 세정을 통하여 상당량의 오염부하를 저감시킬 수 있는 것으로 나타났다.

Law-protected trees are our precious asset as natural resources with history and tradition and natural heritage which should be protected and maintained well to bequeath next generation. Law-protected trees have not only thremmatologic and genetic meaning but also environmental and emotional meaning for their value to be high. This study investigated location, vitality, wrapping condition of root area and status of maintenance of the trees to figure out their growth environment and status of maintenance in a small-middle city through survey on those of law-protected trees in Je-cheon. There showed 300 more year old trees in Je-cheon mostly and the number of trees located in flat fields was the highest. For location type, village, hill and road types were presented in the order and for degree of development, land for building was found most frequently. The average electric resistance of the formative layer was measured to be $8.4k{\Omega}$ and four trees showed bark separation. Most law-protected trees underwent tree surgery, and complete bareness of root area was observed in a tree. The root area of two trees was covered with concrete. pH of soil was recorded to be 5.0~8.4 with its average of 7.1 and electric conductivity(EC) was less than 0.5 dS/m. For status of maintenance rearing facilities were placed for 16 trees out of totally 48 ones and stone fence was done for three ones. Tree surgery was conducted for 33 trees to prevent and to treat decomposed parts of holes. Direction boards were installed for 23 trees. Based on these results, measures to manage systematically law-protected trees in Jecheon could be suggested as follows. First, a sufficient space for growth of low part of trees should be secured. Second, a voluntary management should be induced by advertising them to residents in a community. Third, rearing facilities and direction boards of law-protected trees should be placed and related education should be conducted. Fourth, through operation of the department for law-protected trees consisting of related professions and cooperation among related departments the trees should be maintained continuously.

The Ogcheon and Joseon Supergroups are distributed in the Bonghwajae area, Jecheon-si, Chungcheongbuk-do, Korea which is located in the northeastern fore-end of the Ogcheon Metamorphic Zone. This paper researched the geological structures based on the geometric and kinematic characteristics and the forming sequence of the major multi-deformed rock and microstructures. Most of regional foliations are not the S0 bedding but the S0-1 composite foliations defined by the preferred orientation of stretching minerals, some are recognized as the S0-1-2 composite foliations by the preferred orientation of insoluble opaque minerals and cleavage lamella. The geological structures were formed at least by three phases of deformations i.e. NNE-SSW trending D1, E-W trending D2, N-S trending D3 compressions. The S0-1 composite foliation, which shows a similar zone-distribution trend of the constitution strata of the Ogcheon and Joseon Supergroups, trended WNW before D2 deformation, but it was reoriented into N-S which was parallel to the trend of S2 foliation by D2 deformation, and it was rearranged into NW, NE, N-S trends as it is now by D3 deformation. The structural characteristics of each deformation phase and the deformation history are very similar to those in the eastern domain of Busan area into which the Ogcheon and Joseon Supergroups in this area are extended as NNW trend. It is expected to be very valuable data in interpreting the tectonic evolution of the northeastern fore-end of the Ogcheon Metamorphic Zone.

The function of the Duhak nongak(農樂) in Jecheon consist of Ceremony, Labor, and Entertainment. Before the commemorative rites for village god village people beat a small gong. This is a evidence of the drive away evil spirits in New Year's Eve of the lunar year. Before harden house site village peoples beat musical instrument noisily. In order to press hard the god of the earth they play musical instrument. Musical instrument not a simple musical instrument, but a purify and wish tool. When weeding a rice paddy Durae organized in Sangpung village. Durae are less effective than communal sharing of labor in weeding effect. Nonetheless, Nongak carried out core function in Durae. In order to participate Nonngak concours, peoples made a Pangut. From independence to 1970s people combine traditional nongak and Pangut. Since then village people played Pangut. From 1990s Pangut was played by Duhak Nonngak Preservation Association. Through the participation Nonngak concours, Duhak nongak was regrouped. Finally this nongak prepared Taeguk-jin, Snail-jin, Cross-jin, Sabang-jin, Sanggyeonrae Bans anggyeonrae-jin, Palbang-jin, Rope making and individual play. Duhak Nonngak promptly met the needs of the times. So, they could play Pangut. The feature of the Duhak Nonngak is that active cognition, highly skilled musician a patron and scouting a competent leader.
