The influence of pollutant loads on the water quality in Jeongeupcheon of Dongjin river was evaluated from Jan. 2002 to Dec. 2003 for two years. The range of pH in water was $6.87{\sim}7.53$. The EC level in upstream ranged from 83 to $95\;{\mu}s/cm$ with the highest value in autumn. The BOD level in upstream rang ed from 0.61 to 1.27 mg/L, which would be I grade according to water quality criteria by Ministry of Environment, but that in downstream was III grade. The average T-N level in midstream ranged from 6.10 to 10.84 mg/L which was the highest values throughout the stretch of the river. The average T-P levels ranged from. 0.41 to 0.98 mg/L Jeongeupcheon was suitable for the agricultural usage based upon one year analysis of river water quality. The effluent loads of BOD was high in midstream (J4) with 553 kg/day. The major sources of T-N loads were livestock, population, land use, and industry in order. The effluent loads of T-N was high in J4 by population and industry while that of T-N was high in J5 and J6 by livestock and land use. The delivered loads of T-N was high in downstream The delivered loads of T-P was low as compared with those of BOD and T-N. The delivery ratio of T-N ranged from 6 to 38%.

In this study, we addressed a novel nanosized curdlan-silica complex, which is curdlan bound to silica, for the development of a sustain-releasing micro element fertilizer formulation. The complex was obtained as follow steps; First, Curdlan polymer, sodium silicate ($Na_2SiO_3$) and isopropyl alcohol were dissolved in DDW. Next the resultant solution was irradiated by $^{60}Co$ gamma-irradiator (150 TBq of capacity; ACEL, Canada). Then $MgSO_4$ was treated with the resultant solution. The obtained colloidal solution was dried by freeze dryer. Finally, we obtained a novel nanosized curdlan-silica formulation containing $MgSO_4$ from the colloidal solution. The morphology of the complex was characterized by using scanning electron microscopy (SEM) and transmission electron microscopy (TEM). The nanosized curdlan-silica complex has a particle size ranging from 20 to 80 nm and high stability. Our results suggested that the nano-complex can be applicable to use in various sustain-releasing formulation for pesticide delivery system (PDS).

This study aims to suggest basic data for developing forest product in Jeongeup City by surveying and analyzing consumer awareness and purchasing behavior. A survey was conducted focusing on local tourist attractions in Jeongeup City, and the analysis was conducted on 234 people. Among the local specialty processed products that the survey participants had experience in purchasing, food was mainly tea, concentrate solution, liquor, snacks and fruit syrup/enzyme. The therapy was shown in order of soap, aroma oil, and lotion. It was found that the purchase cost was more than 10,000 won and less than 30,000 won. Major purchase uses were for direct use and gifts, and 56.8% of the customers were satisfied with the satisfaction of the products, which were found to be purchased because of their good quality, good gift, and good health functions. In the question of 11 kinds of forest products, the subjects were aware of bokbunja, balloon flower, wild flower, deodeok, bracken, durum, and mal, among which bokbunja and wild flower were recognized as the representative forest products of Jeongeup. A cluster of food and therapy product selection attributes was analyzed to find target consumers. As the group that is interested in forest products and values the safety and quality of products is highly recognized, the value of forest products should be increased in consideration of the quality and safety of forest products when developing products in the future.

Granitoids in the Younggwang-Kimje area can be divided into two types of granite. One is foliated granite (Cheongup and Kochang foliated granites) developed along the NE-SW direction kwangju fault system and the other is undeformed granite (Kimje and Younggwang granites) developed in the western part of the area. $SiO_2$ content of study area, Younggwang granite is 62.8-74.0%, Kochang foliated granite is 64.5-74.4%, Cheongup foliated granite is 64.5-70.2%, Kimje granite is 63.4-72.0%. The result indicated that these granitoids belong to the intermediate and acidic rock. In Harker's diagram, as $SiO_2$ increases, $Al_2O_3$, $Fe_2O_3$, MgO, CaO, $TiO_2$> $P_2O_{5}$s and MnO decrease, but $K_2O$ increases. In AFM diagram, Younggwang granite, Kochang foliated granite, Cheongup foliated granite and Kimje granite belong to calk-alkaline rock series. And in triangular diagrams of normative Qz-Or-Pl and An-Ab-Or, they are located in granodiorite and granite region. On the co-variation diagrams of trace elements with silica, Ba, Co, Li, Nb, An, Rb elements show increasing patterns. The diagrams of ACF and $Na_2O$ vs. $K_2O$ ratios indicate that granitoids of the study area belong to I-type.

This study was conducted to monitor the irrigation water qualities along Dong-Jin river watershed. The water quality was surveyed at 6 sites from April to september during $1994{\sim}1998$. And the results were as follows : In July and August, water quality was better than that of any other months due to dilution with rainwater. Whereas, it became worse in April but it involved lower contents than limitted contents affected to the crop damage. Content of inorganic components was higher at Jeong-up and Won-pyeong stream. The reason for it that Jeong-up stream was deteriorated with sewage water from Jeong-up city, and Won-pyeong stream has narrow width. Water quality in upstream of Dong-Jin river, was evaluated best conditions in all sampling sites. For investigated period, water quality got worse from 1994 to 1995 but it was getting better to 1998 after 1995, especially at Jeong-up stream. The total equivalent of cation and anion was the highest at April through all months and at Jeong-up stream in sampling sites. Equivalent ratio of cation to $anions({\Sigma}C/{\Sigma}A)$ was higher at May than any other months and lower at Won-pyeong streams than any other sites. The value of most inorganic components was highly correlated with those of other components. But the value of $NO_3\;^--N$ was not correlated with that of most components, and $PO_4\;^{3-}-P$ was not correlated with COD, $NH_4\;^+-N$, $NO_3\;^--N$, $SO_4\;^{2-}$.

이번 고병원성조류인플루엔자(이하 HPAI로 기술)는 2008년 4월 1일 우리 전라북도 김제시 용지면 산란계 밀집 사육지역에서 시작하여 5월 12일 경북 경산시 토종닭 농장을 끝으로 11개 시 도 19개 시 군 구에서 총 33건이 발생되어 2,6410억원의 경제적 피해가 발생하였다. 우리 전라북도는 최초 발생농가를 포함 4개 시 군(익산, 정읍, 김제, 순창)에서 17건(닭13, 오리 4)이 발생하여 전국에서 HPAI발생이 가장 많았던 도로 남는 불명예를 안게 되었다. 이에 막대한 경제적 피해가 다시 발생하지 않도록 HPAI의 현장 방역에 대해 나름대로 경험한 것과 느꼈던 것들을 사례별로 기술하고자 한다.

금년 겨울은 유난히 눈이 많고 추운 것으로 기록되고 있다. 서해안과 전북 지방의 기록적인 폭설과 연일 지속되는 강추위로 정읍, 고창 지역의 양계 농장에 많은 피해가 발생했다. 이처럼 추위와 눈이 많은 겨울철에는 대부분의 농장에서 겪게 되는 것이 호흡기 질병이다. 호흡기 질병이야 일년 열두달 닭을 사육하면 농장에서 끊이지 않는 고질적인 질병이지만 겨울철에는 보온 문제로 인해 환기의 제한을 받다 보니 그 피해가 더욱 심해지고 있다. 따라서 겨울철 계사내 가스 증가와 이로 인한 호흡기성 질병의 증가는 생산성을 저해하는 중요한 요인이 되고 있다. 본고에서는 겨울철에 다발하는 호흡기 질병에 대해 간략히 소개하고자 한다.

근년의 "따뜻한 겨울" 추세와는 달리 2001년 1월 중순은 일주일 이상 혹독한 한파가 지속되었다. 최저기온이 영하 $25^{\circ}C$ 이하를 기록한 지점만도 철원(-29.2$^{\circ}C$), 홍천(-26.7$^{\circ}C$), 동두천(-26.2$^{\circ}C$), 제천(-26.$0^{\circ}C$), 대관령(-25.6$^{\circ}C$) 등 다섯이며, 순천, 진주, 정읍 등 남부지방 여러 곳에서도 영하 15$^{\circ}C$ 이하의 최저기온이 관측되었다.(중략)관측되었다.(중략)
