  • The volcanic ash soils from the Jeju province have low available phosphate because of the high phosphate fixing power of the soils. Phosphorus fertilizerwas dressed after cultivating green manure crops and before cultivating potatoes in order to investigate potato yields, the available phosphate contents, and phosphorus balance in the soils. Green manure crops cultivated in this study were hairy vetch alone and hairy vetch and rye. During potato cultivation, four treatments were conducted in the experiments; NF (non fertilizer), P fertilizer ($N-P-K=0-25-0kg\;10a^{-1}$), NK fertilizer ($N-P-K=18-0-19kg\;10a^{-1}$), and NPK fertilizer ($N-P-K=18-25-19kg\;10a^{-1}$). There were no differences in the yields of potato stem and tuber from the cultivation plots of different green manure crops. However, in the plots with single-sown hairy vetch and mixed-sown hairy vetch and rye, the yields of potato stem and tuber were higher in the P fertilizer plot than in NF plot. The yield of tuber among the treatments with mixed-sown hairy vetch and rye was the highest in the NPK fertilizer plot. The available phosphate content in soils initially increased with time in all plots, but began to decrease gradually after Oct. 18. The available phosphate contents were high in the plots for phosphate fertilization, and the difference in available phosphate content between non-phosphorus fertilizer plots and phosphorus fertilizer plots increased with time. In the single-sown hairy vetch and mixed-sown hairy vetch and rye plot, the phosphorus balances in NF plot and NK fertilizer plot were very low, while those in the P fertilizer plot and NPK fertilizer plot were high. In conclusion, available phosphate contents in soil and the potato yields were increased by phosphorus fertilization when potatoes planted after cultivating hairy vetch and rye together, compared to hairy vetch alone.

  • Lymphocystis is a viral disease of fish primarily in marine and brackishwaters. Here we report the cloning, expression, and the serological applications of the lymphocystis disease virus (LCDV) major capsid protein (MCP). The MCP gene was amplified by PCR from the genomic DNA of LCDV isolated from Schlegel's black rockfish, Sebastes schlegeli, and expressed in E. coli. Mouse antisera raised against the purified recombinant MCP (rMCP) reacted with the viral MCP in an immunofluorescence assay, indicating that this rMCP would be useful for serological studies of field samples.

  • Purpose - This study estimated the value of tourists' willingness to pay (WTP) to develop and promote regional tourism and minimize external effects using the contingent valuation method (CVM). Design/methodology/approach - To reduce exaggeration bias, a major issue of CVM, a pilot survey was conducted to categorize bid value. Additionally, the payment method was divided into a tourism fund and tourism taxes, and the respondents' answers were reaffirmed in two stages. Findings - As a result of the analysis, the tourists' WTP was estimated to be 5,132 KRW (3.60 USD) for the tourism fund and 1,036 KRW (0.73 USD) for tourism taxes. Research implications or Originality - The results of this study provide implications for securing financial resources and establishing policies in Gangwon province, which promotes special self-governing.

  • Jeju Special Self-Governing Province has implemented a self-governing environmental impact assessment system (Jeju-EIAS) in recognition of its autonomy. In this study, the institutional features of Jeju-EIAS were examined by analyzing the development projects whose consultation under Jeju-EIAS were completed from 1994 to 2019. The consultation procedure of Jeju-EIAS, such as the actual operation of Review Committee for Environmental Impact Assessment (EIA), the consent of the provincial council, and the regular follow-up activities for the implementation of EIA consultations, has been implemented differently from those of other metropolitan cities and provinces. Under Jeju-EIAS, types of development projects subject to consultation on EIA also take into account local conditions, and include the construction of aquarium basin and building. In addition, provisions concerning the scale of development projects is strengthened above the Korean Environmental Impact Assessment Act (EIA Act).

  • For 63 soil series distributed in Jeju Island, natural uncultivated soils in each soil series were collected, and their physicochemical properties and their concentrations of 19 heavy metals including 8 heavy metals which are regulated by Korean Soil Environment Conservation Law, were analyzed. Moreover, the correlations between physicochemical properties and heavy metal concentrations, and between heavy metal concentrations were analyzed. The heavy metals distributed in the higher concentrations and the lower concentrations with arithmetric mean value, were Mn(730 mg/kg) and Ba(493 mg/kg), and Hg(0.146 mg/kg) and Tl(0.096 mg/kg), respectively. The correlations between pH($H_2O$) and heavy metals(Hg, Ni, Co, Se), between pH(NaF) and heavy metals(Hg, Ba, Se, Tl), and between organic matter content and heavy metals(Hg, Tl) were significant at the 0.01 level. From the correlations between heavy metal concentrations, there were 22 where there were significant at the 0.01 level and they showed positive correlation. Among those, the heavy metals showing the correlation higher than r=0.5, were Sb-V(0.878), Mo-Sn(0.867), Co-V(0.654), Co-Sb(0.648), Be-Sn(0.546), and Sn-Tl(0.528).

  • 제주지역 양식 넙치의 주요 세균성 질병의 일종인 연쇄구균증 원인균 Streptococcus iniae 및 Streptococcus parauberis에 대한 생물학적 특성을 시험하였다.온도별 성장 시험결과 S. parauberis 균주는 10℃ 배양조건에서 성장이 이루어졌으나 S. iniae 균주의 경우는 10℃에서는 성장이 확인되지 않았으며, 용혈성 시험결과에서는 S. iniae 균주의 경우에만 β용혈성을 나타내었다.생화학적특성 시험결과 acetoin production test (VP test), hippurate hydrolysis test (HIP test)에서는 S. parauberis 균주의 경우에만 양성반응을 보여 두 균주사이에 뚜렷한 차이를 보였다.또한 α-D-glucose, D-mannose, D-psicose, D-trehalose, pyruvatic acid methyl ester, glycerol은 두 균주 모두 기질로 이용하였으나 L-lactic acid는 S. iniae 균주만이 이용하였고, β-methyl-D-glucoside의 경우는 S. parauberis 균주만이 기질로 이용하는 것으로 나타났다.병원성 시험결과, S. iniae는 급성감염 형태를 보인 반면에 S. parauberis는 만성 감염형태를 보임으로써 차이를 나타내었다.

  • 계약심사제도는 지방재정 효율화를 위한 사전예산절감 모델로 계약심사제도가 도입 운영되고 있다. 그러나 계약심사제도는 발주처에게는 예산절감이라는 측면으로, 업체에게는 예산삭감이라는 측면으로 인식되어 계약심사제도에 대한 상반된 이해구도가 형성되고 있다. 본 연구에서는 제주특별자치도에서 운영 중인 계약심사제도가 사전예산절감 모델로서 올바르게 정착하기 위한 발전방안을 제안하고자 추진되었다. 이를 위해 계약심사자료를 기초로 계약심사제도의 운영현황 분석과 지자체와 업체의 계약심사제도에 대한 인식도를 분석하였다.
