To compare the contents of well-known effective constituents, paeoniflorin, albiflorin and benzoic acid, of Korean paeony roots cultivated at different regions, this study was to provide the basic information for the quality evaluation of paeony roots. HPLC analysis showed that the paeoniflorin contents of white paeony roots of 3 years grown at Eui-seong gun, Kyungpook was the highest of 2.06% and red paeony roots of 3 years grown at Im-sil gun, Junpook was the lowest of 1.33%. The highest level of albiflorin contents was 2.04% of red paeony root grown at Ul-jin gun, Kyungpook, while the lowest levels were 0.05% of Eui-seong gun, Kyungpook and 0.06% of Im-shil gun, Junpook. The highest level of benzoic acid contents was 0.12% of red paony roots grown at Choung-do gun, Kyungpook and that grown at Ul-jin gun, Kyungpook was the lowest. Based on the average of three available constituents, the paeony roots cultivated at Kyungpook province was the highest contents of 2.03%, while 1.47% at Junpook province. These results suggest that Kyungpook province is the best region for the cultivation of white and red paeony roots, the combining of three available constituents would be more accurate than use of paeoniflorin only.

Korea's water supply efficiency is low, due to weak industrial structure, such as small scale, regional disparities in the management and services, unreasonable problem in a use and management of interregional water resources. This study investigated changes in the productivity of Jeollabuk-do local water supply service by using analysis of efficiency by data envelopment analysis and Malmquist Index Analysis. As a result, 6 office is showed that the value of scale efficiency is 1 and productivity index per gun in mainly seemed below average. Therefore these offices should strive to increase their productivity. This study is differentiated from earlier studies in the aspect of measuring change of productivity by not only DEA but also Malmquist productivity analysis. Therefore it will contribute to increase productivity of water supply in Jeollabuk-do.

This study was conducted to estimate the water quality of agricultural groundwater well located in Buan-gun, Jinan-gun, Sunchang-gun, and Jangsu-gun of Jeollabuk-do. The groundwater samples were collected at 328 sites (Buan-gun: 158, Jansu-gun: 45, Sunchang-gun: 32, Jinan-gun: 93, respectively). We measured 4 kinds of general contaminants (pH, $NO_3-N$, $Cl^-$, and COD) and 10 kinds of specific contaminants (Cd, As, $CN^-$, Hg, phenol, Pb, $Cr^{+6}$, organophosphorus, trichloroethylene, and tetrachloroethylene). Generally, the level of general contaminants and specific contaminants in the agricultural groundwater was suitable for water quality standard in all sites for agricultural irrigation water. Exceptionally, chloride concentrations were exceeded water quality standard of agricultural groundwater at some sites in western coast area of Jeollabuk-do. Although water quality standards in agricultural groundwater have been suitable, the water contaminants of agricultural groundwater in western coast area were gradually increased than eastern mountain area.

This experiment was conducted to study about nutrient absorption of flag leaf and chaff of rice plant different transplanting date with elevations. Heading stage was delayed by destructive cold temperature or late transplanting. Plant analyses revealed that above poor plants also had higher total nitrogen content, but ower silicate in the flag leaf and sterile chaff. Total nitrogen and silica contents to accumulated in flag leaf between yield was significant high correlation. The chaff of late transplanting and sterility was high total nitrogen. Relationship between silicate absorption and total nitrogen of chaff was significant high correlation. Ripening temperature after heading stage was influenced total nitrogen of chaff. Phosphate, potassium, calssium and silicate contents of chaff increased hight ripening temperature but total nitrogen decreased. Therefore, inorganic element contents of chaff was closely connected with grain sterility.

This study was conducted to determine the proper time of corn marketing by cultivating time movement and cultural practice system establish. The rate of development of corn from planting to anther is a function of temperature rather than of photosynthesis. The major yield components of sweet corn for yield increase are more ear heavier grain weight, greater of kernels and heavier 100 grain weight. Early sowing has show yield decrease because yield capacity decreased with the shorting of vegetative growth and it was relatively susceptible to maize black streaked dwarf virus.

Outbreaks of highly pathogenic avian influenza(HPAI) subtype H5N8 have occurred in Korea, January 2014 and it continued more than a year until 2015. And more than 5 million heads of poultry hads been damaged in 196 farms until May 2014. So, we studied the spatial, temporal and spatio-temporal patterns of the HPAI epidemics for understanding the propagation and diffusion characteristics of the 2014 HPAI. The results are expressed using GIS. Throughout the study period three epidemic waves occurred over the time. And outbreaks made three clusters in space. First spatial cluster is adjacent areas of province of Chungcheongbuk-do, Chungcheongnam-do and Gyeonggi -do. Second is Jeonlabuk-do Gomso Bay area. And the last is Naju and Yeongam in Jeollanam-do. Also, most of spatio-temporal clusters were formed in spatially high clustered areas. Especially, in Gomso Bay area space density and spatio-temporal density were concurrent. It means that the effective prevention activity for HPAI was carried out. But there are some exceptional areas such as Chungcheongbuk-do, Chungcheongnam-do, Gyeonggi-do adjacent area. In these areas the outbreak density was high in space but the spatio-temporal cluster was not formed. It means that the HPAI virus was continuing inflow over a long period.

Recently, small libraries have greatly increased by the support and interest of the central, or local government. Since 2004, 47 small libraries were established in Jeon-buk province. These libraries are equipping a new facility and collection with their support. Nevertheless, they still have many problems in operating process. This is causing degradation of the quality level of information service for local residents, further, this becomes the obstacle which solves a information divide and improves the cultural welfare. The purpose of this study is to analyze the status of small libraries in Jeon-buk province, and then, to propose solutions to problems.

국내 11개 지역(경기도 옹진군 덕적도, 경기도 의정부시 소요산, 강원도 춘천시, 충청남도 태안군 안홍, 경상북도 울릉군 울릉도, 전라북도 부안군 변산, 전라남도 신안군 홍도, 흑산도 비금도, 진도, 제주도)에서 채집된 달팽이 (A. despecta sieboleiana)를 대상으로 외부형태 분석과 동위효소를 검출하여 각 지역 집단간의 형태적, 유전적 유연관계와 변이 정도를 연구한 결과는 다음과 같다. 외부형태에 의한 집단간 유연관계는 안홍과 덕적도집단(average taxonomic distance, D=0.358)이 형태적으로 가장 유사한 집단으로 나타났다. Polyacrylamide gel을 사용하여 11가지의 동위효소를 검출한 결과 AKP, ACP, AO, EST, GPD, HBDH, LDH, SDH, XDH의 동위효소에서 유전적 다형현상이 나타났다. 전 집단의 평균 다형형의 빈도는 59.19%이며 이형접합자 빈도는 0.263이고 각 집단의 유전적 차이치는 춘천과 울릉도 집단이 0.066(genetic distance)으로 가장 높은 유사성을 보였다. 지리적 분포에 따른 외부형태 변이와 유전적 변이와의 관계는 유의성이 없었다.
