  • Geothermal springs in India, formed as a result of volcanic or tectonic activities, are characterized by high temperature and relatively abundant reduced compounds. These thermal springs are inhabited by characteristic thermophilic organisms including cyanobacteria. Cyanobacteria are among the few organisms that can occupy high temperature aquatic environments including hot springs. In alkaline and neutral hot springs and streams flowing from them cyanobacteria can form thick colourful mats that exhibit banding patterns. The present investigation involves study of mat forming cyanobacterial flora from hot springs located in Bakreswar, West Bengal, India. The important species found are Synechococcus bigranulatus, S. lividus, Gloeocapsa gelatinosa, G. muralis, Phormidium laminosum, P. frigidum, Oscillatoria princes, O. fragilis, Lyngbya lutea, Pseudanabaena sp., Calothrix thermalis, and Fischerella thermalis. Their distribution pattern in relation to physico-chemical parameters of spring water has also been studied. Three cyanobacterial strains of the above mentioned list were grown in culture and their pigment content and nitrogen fixing capacity were also studied. Nitrogen fixing capacities of Calothrix thermalis, Nostoc sp. (isolated in culture) and Fischerella thermalis are 5.14, 0.29, and 2.60 n mole $C_2H_4/{\mu}g$ of Chl-${\alpha}$/hr respectively. Carotenoid : Chlorophyll-${\alpha}$ ratio of four mat samples collected from Kharkunda, Suryakunda, Dudhkunda and bathing pool are 2.45, 1.60, 1.48, and 1.34, respectively. Higher value of Carotenoid : Chlorophyll-${\alpha}$ ratio coincided with higher temperature.

  • In this paper, a computer simulationtechnique for the forging process having a spring-attached die was presented . The penalty rigid-thermoviscoplastic finite element method was empolyed together with an interatively force-balancing method, in which the convergence was achieved when the forming load and the spring reaction force are in equilibrium within the user-specified allowable accuracy. The force balance was controled by adjusting the velocity of the spring-attched die. th minimize the number of internations, a velocity estimating schemewas proposed. Two application examples found in the related company were given. In the first application example, the predicted metal folw lines were compared with the acturally forged ones. in the second example, a hot forging process with a spring-attached die was simulated and the analyzed results were discussed in order to investigated the effects of spring-attached dies on the metal flow lines and the forming loads.

  • 내열성 $\beta$-glycosidase 효소를 생성하는 균주를 분리하기 위해서 일본의 Atagawa 온천지역에서 시료를 채취하였다. 조효소액이 $70^{\circ}C$에서 4시간 동안 $\beta$-glycosidase활성을 유지하는 KNOUC 202를 선발하여 분리, 동정하였다. 선발된 KNOUC 202는 호기성으로 그람음성 간균이며, 포자를 형성하지 않으며, 운동성이 없으며, carotenoid를 생성하고, catalase, oxidase 양성으로 나타났으며, 최적 성장온도는 $70~72^{\circ}C$이고, 최적 pH는 7.0~7.2이었으며, NaCl 3% 농도에서 성장하였다. 세포내 지방산의 주성분은 iso-15:0과 iso-17:0이었다. KNOUC 202의 16S rRNA sequence는 Thermus thermophilus ATCC 27635(HB8)와 유사도가 99.9% 이었다. 따라서 형태학적, 이화학적, 생화학적 특성, 지방산조성 및 16S rRNA sequence 분석결과에 근거하여 KNOUC 202를 Thermus thermophilus로 동정하였다.

  • 문경지역 온천은 칼슘-중탄산 온천으로 원수의 온도는 약 $28.5^{\circ}C$이다 원수는 EC(1,857 $\mu\textrm{s}$/cm), $HCO_3$ (1,250 mg/l), $SO_4$(147.60 mg/l), Mg(43.05 mg/l) . 그리고 Ca(279.43 mg/l)로 상당히 높은 값을 나타낸다. 원수에는 소량의 침전물이 형성되지만 보일러로 가열할 경우 많은 양의 침전물이 형성된다. 원수에서 침전되는 광물은 대부분 방해석이지만 보일러실에는 아라고나이트와 방해석이 동시에 정출된다. 온천수 내의 화학종은 $CO_3$는 대부분 $HCO_3^{-}$ 이지만 상당 부분이 $H_2$$CO_3$로, $SO_4$$SO_4^{2-}$ , Mg는 $Mg^{2+}$ Ca는$ Ca^{2+}$ 로 존재한다. 전체적으로 볼 때 대부분의 성분에서 $CO_3$를 포함한 화학종이 존재하는 것을 볼 수 있다. 포화지수를 근거로 침전 가능한 광물은 다이아스포어, 보에마이트, 깁사이트, 아라고나이트, 방해석, 능철석 등이지만 X-선회절 분석결과 침전물은 아라고나이트, 방해석, 철수산화물로 구성되어 있다.

  • 1. Objective : The purpose of this study is to investigate the effects of TAM (Taraxacum mongolicum) on Th2 cytokine production in MC/9 mast cells. 2. Methods : The effects of TAM was analyzed by ELISA and Real-time PCR in MC/9 mast cells. Levels of IL-5, IL-13 were measured using enzyme-linked immunosorbent assays(ELISA). mRNA levels of IL-4, IL-5, IL-6, IL-13 were analyzed with Real-time PCR. 3. Results : 1) TAM inhibited the IL-4 production significantly in comparison to PI-control group at concentration of $50{\mu}g/ml$, $100{\mu}g/ml$, $200{\mu}g/ml$. 2) TAM inhibited the IL-13 production significantly in comparison to PI-control group at concentration of $50{\mu}g/ml$, $100{\mu}g/ml$, $200{\mu}g/ml$. 3) TAM inhibited the IL-4 mRNA expression significantly in comparison to PI-control group at concentration of $100{\mu}g/ml$. 4) TAM inhibited the IL-5 mRNA expression significantly in comparison to PI-control group at concentration of $50{\mu}g/ml$, $100{\mu}g/ml$. 5) TAM inhibited the IL-6 mRNA expression significantly in comparison to PI-control group at concentration of $100{\mu}g/ml$. 6) TAM inhibited the IL-13 mRNA expression significantly in comparison to PI-control group at concentration of $100{\mu}g/ml$. 4. Conclusions : These results indicate that TAM (Taraxacum mongolicum) has the effect of decreasing the Th2 cytokine production in the MC/9 mast cell.

  • Twenty-two water samples(fifteen groundwater and seven geothermal water samples) were collected to elucidate chemical characteristics of the ground and geothermal waters in the Haeundae hot spring area and its vicinity. Major and honor elements were analyzed for ground and geothermal water samples. The concentrations of $K^+$, Na+$, $Ca^{2+}$, $SO_4^{2-}$, $Cl^-$, ^F^-$ and $SiO_2$ were higher in the geothermal water samples than the groundwater samples except $HCO_3^- and Mg^{2+}$ ions. Based on the contents of Fe, Zn, Cu, Al, Mn and Pb, some of the ground and geothermal water samples are contaminated by anthropogenic sources. The ground waters shown on the Piper diagram belong to $Ca-HCO_3$ type, while the geothermal waters Na-Cl type. The graphs of $Cl^-$ versus $Na^+$, $Ca^{2+}, Mg^{2+}, K^+, SO_4^{2-} and HCO_3^-$ indicate that the groundwater is related partly with mineral-water reaction and partly with anthropogenic contamination, while the geothermal water is related with saline water. On the phase stability diagram, groundwater and thermal water mostly fall in the field of stability of kaolinite. This indicates that the ground and geothermal waters proceed with forming kaolinite. Factor and correlation analyses were carried out to simplify the physicochemical data into grouping some factors and to find interaction between them. Based on the Na-K, Na-K-Ca and Na-K-Ca-Mg geothermometers and silica geothermometers, the geothermal reservoir is estimated to have equilibrium temperature between 125${$\mid$circ}C$ and 160${$\mid$circ}C$.

  • 1985년에 온천관광지 조성계획이 추진되었으나 2017년 현재까지도 지역간 환경갈등이 지속되고 있는 '문장대 온천 관광지 조성사업' EIA의 사례연구를 통하여 환경소송의 한계와 ADR로서 EIA 제도의 적용가능성에 대하여 고찰하였다. 환경영향의 과학적 사전예측으로 사회갈등 환경갈등을 예방하기 위한 민주적 절차인 EIA 제도를 통하여 지역주민 의견수렴 및 'EIA 협의의견'을 환경 거버넌스 차원에서 의사결정 과정에 반영하면 환경소송의 폐해를 미연에 방지하게 되어 ADR로 기능할 수 있다. 우리나라에서도 EIA 주민참여 범위를 'Aarhus 협약' 수준으로 확대된 공중의견 수렴제도를 점진적으로 도입하여 실질적인 ADR 기능을 강화시킬 수 있다. 막대한 영향을 미치는 개발계획 및 개발사업에 관련된 의사결정 과정에 공청회 등의 거버넌스를 통하여 사회적 형평성 및 환경적 지속가능성을 핵심으로 하는 EIA 제도는 궁극적으로는 우리나라의 지역차원에서 SDG를 구현시킬 수 있는 적합한 ESSD 수단이 될 수 있다.

  • 온천배수에 의한 주변 식물상의 변화를 구명하기 위하여 고창 석정온천, 전주 죽림온천, 익산 왕궁온천을 대상으로 1997년부터 1998년까지 10회에 걸쳐서 조사하였다. 계절별 온배수에 의한 주변 식물종의 출현은 외부기온이 비교적 낮은 계절에 대조구보다 실험구에서 더 많은 종이 나타났다. 피도가 높은 종은 계절에 따라 바뀌지만 대조구와 실험구에서 차이가 없었다. 온배수에 의한 식물 엽면적의 계절별 변화는 대체로 2월, 4월, 10월에는 대조구값이 오염지역 식물보다 낮았다. 이것은 온배수에 의한 온도상승이 요인으로 판단되었다. 계절별 식물의 생체량과 건중량은 외부기온이 비교적 낮은 때에는 대조구 값이 실험구 값보다 저조하였다. 온천 배수지역의 식물체내에 함유된 무기염류의 분석결과 석정온천 지역의 Cu, Zn, Ni, Pb는 대조구보다 오염지역에서 4월부터 9월까지 증가하였고 10월에는 감소하였다. 왕궁온천 지역의 식물체 내에는 Zn, Pb함량이 대조구보다 오염지역의 값이 높았다. 그래서 온배수에 의한 식물의 영향은 기온이 낮은 계절에 나타나고, 기온이 높은 계절에 식물은 회복되는 것으로 밝혀졌다.

  • An extracellular agarase was purified from Bacillus sp. BI-3, a thermophilic agar-degrading bacterium isolated from a hot spring in Indonesia. The purified agarase revealed a single band on sodium dodecyl sulfate-polyacrylamide gel electrophoresis, with an apparent molecular mass of 58 kDa. The optimum pH and temperature of the agarase were 6.4 and $70^{\circ}C$, respectively. The activity of the agarase was stable at high temperatures, and more than 50% activity was retained at $80^{\circ}C$ for 15 min. Furthermore, the enzyme was stable in the pH range of 5.8-8.0, and more than 60% of the residual activity was retained. Significant activation of the agarase was observed in the presence of $K^+$, $Na^+$, $Ca^{2+}$, $Mg^{2+}$, and $Sr^{2+}$; on the other hand, $Ba^{2+}$, $Zn^{2+}$, $Cu^{2+}$, $Mn^{2+}$, $Co^{2+}$, $Fe^{2+}$, and EDTA inhibited or inactivated the enzyme activity. The components of the hydrolytic product analyzed by thin-layer chromatography showed that the agarase mainly produced neoagarobiose. This study is the first to present evidence of agarolytic activity in aerobic thermophilic bacteria.
