ABSTRACTThe chlorine has been used as one of the drinking water supply system, it be used universally the most economic chemical treatment and effect chemical threatment.But, in chlorine treatment, the residual chlorine in drinking water reacts with organic materials (humic substances), and to produce THMs(trihalomethanes) which is known as carcinogenic substance.In the experiment, sample of drinking water was mixed that chlorine used in the original disinfectants were summaried as be more effect then the above single treatment (chlorine) dissolved oxygen, KMnO4 consume degree, and ferric, phenol, general bacteria, trihalomethanes.

왜 19세기 후반기 독일경제인가?:국가경쟁력과 경제사 연구
박영구 釜山外國語大學校國際通商硏究所 1998 國際經營論集 Vol.13 No.-
19세기 후반기 유럽경제는 세계경제사의 전환을 가져온 장기적 불황, 세계시장의 확대, 국제경쟁의 격화 시대를 겪었다. 1차산업혁명에 먼저 성공한 영국 주도의 세계경제 구조는 19세기 중엽까지 고정적인 구조로 유지되었지만 19세기 후반기 들어 서면서 이러한 일극중심의 세계경제구조는 변화를 맞고 있었다. 유럽에서는 프랑스, 이탈리아, 러시아 등과 함께 독일이 1차 산업화에 성공하였고 미국의 산업이 급속히 성장함으로써 서서히 다극적인 구조로의 전환이 시작되고 있었다. 경제정책에서도 1879-90년에 걸쳐 독일, 프랑스, 미국이 보호관세의 성격을 일제히 보임으로써 자유무역에 입각한 정통경제이론의 혼란도 나타났다. 여기에 19세기 마지막 한 분기인 1873년부터 1895-6년까지의 '소위 대불황(Great Depression)'은 물가의 대폭적인 하락을 가져와 1896년 유럽각국과 미국의 都賣物價指數는 1873년=100에 비해 58.5-60.0 수준으로 떨어졌다. 이런 속에서 유럽각국의 경제이론과 경제정책은 시험대에 오르고 있었다.

대형유통업체의 농산물 산지계약거래에 관한 연구-천안지역의 대형유통업체를 중심으로-
박영구,김호 한국농업정책학회 2002 농업경영정책연구 Vol.29 No.4
The objective of this study is to analyze difference of buying pattern among modern chained supermarkets for agricultural products and to derive development strategy for farmer, farmer`s organization and Agricultural cooperatives. And then provide agricultural producing districts with suggestive point. The service market of agricultural products has been completely opened with exception of some grain and beefs since 1996. Therefore overseas modern chained supermarkets have actively extended their business in Korea. Provide for this situation, domestic leading enterprises have also restructured their business operation. Since Korean economic crisis in 1997, the consumption pattern has been changed more rational than before. This urban consumption shift makes modern chained supermarkets gradually increase amount of sale. And then agricultural products play an important role as commodities for their sales promotion. In order to induce many guest, These enterprises have been directly buying from the district which agricultural products are grown. This direct marketing can reduce the number of marketing channel and increase farmers` income.

朴榮九 숭실사학회 2016 숭실사학 Vol.0 No.36
본고에서는 최근 조사가 활발하게 이루어지고 있는 북한강유역과 남한강유역에 입지한 청동기시대 유적에서 조사된 주거지의 구조와 토기양상에 주목하여 강원영서지역 취락의 전개양상을 검토해 보았다. 강원영서지역 청동기시대 주거지의 변화는 대형 장방형으로부터 세장방형을 거쳐 방형화 되는 평면형태의 변화와 함께 위석식에서 토광식으로 노가 변화한다. 북한강유역의 경우 주거의 구조상 여러 요소가 복합된 위석식 노와 토광식 노가 주거 내에 공존하고, 점토다짐구역 마련 이전의 작업공 배치, 천전리유형의 주거와 소형 방형 주거 등 남한강유역에 비해 복잡한 양상을 보인다. 그러나 두 유역권 모두 토기의 문양구성상 복합문양에서 단일문양으로의 변화와 무문화 경향은 공통적인 양상으로 파악된다. 전기에는 역삼동문화유형 분포권의 공간적 확대로 인하여 북한강유역에서는 기존 미사리유형 취락을 재편한다. 반면에 남한강유역은 미사리유형과 동북한계 문화요소가 혼합된 조동리유형이 전기 늦은 시기까지 지속되는 차별적 양상을 보이는 것으로 판단된다. 강원영서지역 청동기시대 취락의 분포정형은 산간지대에 교통로와 연결되는 하천변을 따라 중심취락을 중심으로 양쪽에 일반취락이 열상분포를 이루는 형태인 양방형 연계망이 형성되었던 것으로 판단된다. This paper includes research on the development of settlements in the Yeongseo region of Gangwon-do based on the remains of dwellings and potteries discovered at the Bronze Age sites near the Bukhangang and Namhangang Rivers, which have been comprehensively surveyed in recent years. The Bronze Age dwelling sites in the area around Yeongseo in Gangwon-do underwent changes in terms of the floor shape and hearths. The large-sized rectangular floor was changed into square throughout the thin-rectangular, with the upstanding stone hearth replaced by plain pit hearth. With regard to the settlements along Bukhangang River, both types of hearths appear to have been installed in residences based on the living structure. In addition, the features of the settlements around Bukhangang River -- such as the arrangement of workspace before building the compacted clay ground, Cheonjeon-ri-type dwelling site, and small-sized square dwelling site -- show that it is more complex than the sites around Namhangang River. However, the two settlements have a common feature in that the pottery patterns underwent the same changes. The mixed patterns were eventually replaced with a single pattern, and there was a marked tendency toward plain pottery. In the early period, the existing Misa-ri type settlements around the Bukhangang River were reorganized in accordance with the enlargement of the area of distribution of the Yeoksam-dong type culture. Meanwhile, around the Namhangang River, a new local culture (Jodong-ri type) was created when cultural elements of the Misa-ri culture were combined with elements from Northeast Korea, which lasted into the late early period. The distribution pattern of Bronze Age settlements in the Yeongseo region of Gangwon-do developed into a two-way connection network. The network was composed of major settlement and general settlements on both left and right sides of the major settlement distributed in the mountainous areas along the riversides, which were connected to traffic routes.

A Case Study of Desulphurization by Limestone Adsorbent in an Industrial CFBC Boiler
박영구,조영민,김승호 한국대기환경학회 2005 한국대기환경학회지 Vol.21 No.E2
Domestic anthracite contains a large amount of fine particles, which causes to fire the back side of theboiler and to form the clinker deteriorating the combustion efficiency. At this time, the fine limestonemode of limestone (0.1 mm) has been used no more than 25% in local power stations of Korea. Thepresent test carried out with an in-situ boiler, however, showed that higher content (up to 50%) of finelimestone particles did not entail any mal-function. In addition, the desulphurization was found to be asgood as the old mode of limestone adsorbents.
