박미선,전세규,Park, Mi-Seon,Chun, Seh-Kyu 한국어병학회 1989 한국어병학회지 Vol.2 No.2

1986년(年) 1월(月)부터 1988년(年) 12월(月)까지 3개년(個年)에 걸쳐 남해안(南海岸) 굴 수하식(垂下式) 양식장(養殖腸)인 충무 화도, 서해안(棲海岸) 투석식(投石式) 양식장(養殖腸)인 오천, 그리고 자연(自然) 서식장(棲息腸)인 동해안(東海岸) 신창의 참굴을 대상으로 Marteilioides chungmuensis의 생태학적(生態學的) 및 형태학적(形態學的) 조사(調査)를 실시(實施)한 결과(結果)를 요약(要約)하면 다음과 같다. 1. 1986년 화도 양식장(養殖腸)에서 채집(採集), 조사(調査)된 총(總) 360개체(個體)의 참굴 중(中) M. chungmuensis가 발견(發見)된 개체(個體)는 19개체(個體)로 5.3%의 출현율(出現率)을 나타내었으며, 오천 양식장(養殖腸)에서 360개체중(個體中) 15개체(個體)로 4.2%, 그리고 1987년(年) 화도 양식장(養殖腸)에서는 총(總) 360개체(個體) 중(中) 24개체(個體)가 발견(發見)되어 6.7%, 오천 양식장(養殖腸)에서는 360(個體) 중(中) 10개체(個體)로 2.8%의 출현율(出現率)을 나타내었다. 그러나 1986년(年)과 1987년(年) 동해안(東海岸)의 신창에서 채집(採集)된 총(總) 720개체(個體)의 참굴 중(中) M. chungmuensis가 발견(發見)된 참굴은 없었다. 2. 1988년(年) 3월(月)에서 12월(月)까지 M. chungmuensis가 전혀 발견(發見)되지 않은 동해안(東海岸) 신창산(産) 참굴을 남해안(南海岸)의 화도로 이식(移植)하여와 감염율(感染率)을 조사(調査)한 결과(結果), 이식(移植)된 신창산(産) 참굴에 있어서는 5월(月)부터 M. chungmuensis에 감염(感染)된 개체(個體)가 나타나기 시작하였으며, 총(總) 300개체(個體)의 조사(調査) 굴 중(中) 25개체(個體)가 M. chungmuensis에 감염(感染)된 것으로 나타났다. 3. M. chungmuensis의 출현(出現) 시기(時期)는 화도의 경우 6월(月)부터 11월(月), 오천의 경우 6~10월(月)사이로 참굴의 산란(産卵)이 시작되는 시기(時期)부터 완전히 종료(終了)된 후 2개월까지의 시기(時期)였으며, 산란(産卵)이 진행됨에 따라 M. chungmuensis의 출현율(出現率)은 점점 감소(減少)하는 경향(傾向)이었다. 4. M. chungmuensis에 감염(感染)된 성숙란(成熟卵)은 산란(産卵)이 진행됨에 따라 일부는 정상적(正常的)인 난(卵)과 함께 아가미를 통하여 배출되고, 나머지 생식소(生殖巢)에 남아있는 M. chungmuensis에 감염(感染)된 난(卵)은 생식소내(生殖巢內)에서 붕괴, 사멸되는 것으로 나타났으며, 이 기생충(寄生蟲)에 감염(感染)된 참굴에서는 생식소(生殖巢)의 여포(濾胞)주위에 강한 혈구성(血球性) 침윤(浸潤)이 나타나는 것을 관찰할 수 있었다. 5. 이 기생충(寄生蟲)의 난소내(卵巢內) 성숙과정(成熟過程)의 관찰결과(觀察結果) M. chungmuensis는 성숙(成熟)한 난모세포(卵母細胞)의 세포질내(細胞質內)에 근세포(根細胞), 즉 1 차(次) 세포(細胞)로 자리잡게 되며, 이 기생충(寄生蟲)은 포자형성(胞子形成) 기간(期間)동안 외생발아(外生發芽)에 의해 2 개 또는 3 개의 2 차(次) 세포(細胞)를 형성하며, 내생발아(內生發芽)에 의해 1 개의 3 차(次) 세포(細胞)를 형성하고, 2 차(次) 세포(細胞)는 성장하여 포자모세포(胞子母細胞)로 되는 phylum Ascetospora, class Paramyxea에 속하는 종(種)들 중 가장 단순한 성숙과정(成熟過程)을 거치는 것으로 나타났다. An ovarian parasite, Marteilioides chungmuensis of the Pacific oyster, Crassostrea gigas has been observed on several occasions in the Pacific sector of production of this oyster species(Matsuzato et al., 1977 ; Chun, 1979). This study was carried out on the specimens collected at Hwado, Och'$\check{o}$n, and Sinchang respectively located the southern, western, and eastern coasts of Korean Peninsula from 1986 through 1988 to investigate M. chungmuensis to the Pacific oyster. Uitrastructural studies were also carried out on infected oysters, to allow detailed examination of the structure and consepuently the systematic position of this parasite. Infection rates of M. chungmuensis at Hwado and Och'$\check{o}$n oyster farms were 5.3% and 4.2% each in 1986, 6.7% and 2.8% each in 1987, but they were not found at Sinchang oyster habitat. M,. chungmuensis-infected oysters were found from June to November at Hwado and from June to October at Och'$\check{o}$n. Twenty five of three hundred oysters transplanted from Sinchang to Hwado were found infected with M. chungmuensis. Some abnormal eggs infected with M. chungmuensis are liberated through the gill together with normal mature eggs on the spawning and the rest remain necrotized after spawning season. The earliest known stages consist of a stem cell or primary cell, including a secondary cell in which ovoid haplosporosomes are found. During sporulation, 2 or 3 secondary are produced by exogenous budding from the first secondary cell and, each secondary cell evolves into a sporont upon the tertiary cell differentiation (enodogenous budding) ; then, haplosporosomes are formed in the young sporont. Internal cleavages involve the differentiation of one tricellular spore per sporont. The outermost spore cell contains membrane-bounded osmiophilic bodies : the middle and the inner, most spore cells contain high density cytoplasmic ribosomes. The mechanism of spore formation from the stem cell of M. chungmuensis is the simplest of the class Paramyxea known up to now.

Synechocystis sp. PCC 6803으로부터 광활성 종속영양 생장결핍 돌연변이체의 분리 및 특성

A mutant strain PRM1 defective in light-activated heterotrophic growth was isolated from Synechocystis sp. PCC 6803. PRM1 could be grown at growth rate equivalent to Synechocystis 6803 under mixotrophic growth conditions. However, PRM1 could not be grown under light-activated heterotrophic conditions, in which a daily pulse of light for 5 min was given. These results suggest that PRM1 is not defective in heterotrophic metabolism, but in the transduction pathway of light signal essential to the growth. Plasmid patterns, absorption spectra of whole cells, and the exterior and interior structures of PRM1 were similar to those of Synechocystis 6803, except that PRM1 could not produce amorphous slime holding cells together. Bacillus megaterium ATCC 14945의 penicillin G acylase 유전자의 염기배열을 결정하였다. 이 유전자에는 2,406 염기쌍으로 이루어진 하나의 open reading frame이 존재하는데, 개시코돈의 5' 위쪽에서 Shine-Dalgarno 배열과 promoter로 여겨지는 부분을 발견하였으며, 종결코돈의 3' Synechocystis sp. PCC 6803으로부터 광활성종속영양으로 생장할 수 없는 돌연변이체 PRM1을 분리하였다. PRM1을 혼합영양으로 배양하였을 경우에는 생장속도가 Synechocystis 6803과 거의 같았다. 그러나 PRM1을 하루에 5 분만 빛을 조사하면서 광활성종속영양으로 배양하였을 경우에는 전혀 생장하지 못하였다. 이러한 결과는 PRM1이 종속영양으로 생장하는데 필요한 대사능력에 이상이 있는 것이 아니라 생장에 필요한 광신호 전이 체계에 이상이 있음을 시사한다. PRM1의 plasmid 양상, 균체의 absorption spectra, 세포 내부와 외부의 형태 등은 Synechocystis 6803과 유사하였으나 여러 세포들을 함께 얽어매는 부정형 점액성 물질을 형성하지 않는 점이 달랐다.

일방적 ㆍ 비현실적 재건축 규제 재정비해야

박미선,Park, Mi-Seon 한국주택협회 2006 주택과 사람들 Vol.199 No.-

참여정부는 강남의 재건축 시장을 전국의 집값을 올리는 주범으로 몰아 개발이익환수, 임대아파트 건립 중 각종 규제책을 쏟아냈다. 결국 집값 안정을 위한 명목으로 수많은 정책을 내놓았지만, 정작 집값은 잡히지 않고 도시 관리 등 부동산 시장의 총체적인 문제점이 생겨나고 있다. 또 일방적인 재건축 규제책으로 각종 부작용마저 생겨 법률안이 제대로 시행되는 데는 많은 어려움이 있을 것으로 보인다. 2006년 한 해 재건축 · 재개발 시장 동향과 정부의 정책적 대응은 어떠했는지 알아본다.

Infectioa rates of oyster ovariaa parasite, Marteiliodes chungmuemsis and prodactivity of the oyster shellstock infected with the parasite were investigated at the main seed collection areas in the soathern coast of Korea where the extreme bad seed collection of oyster occurred in 1992 and 1993 to evaluate the cause of the bad seed collection. Additionally, the bacterial flora of the sea water sud oyster larva were examined to identify the shellfish larva pathogenic bacteria like Vibrio sp. and Pseudomonas sp. In August 1992 to September 1993, infection rate of oyster ovarian parasite, M. chungmuensis at Tongyong, Kyongsangnam province, and Yosu, Chollanam proviace where the bad seed collection occurred, were 11.8∼100% and 14.3∼100%, respectively. Bat the parasite was not detected in the shellstock collected at Daechon, Chungchongnam province. While a virus-like particle was identified in the cytoplasm of the egg infected by the parasite. The parasite infected egg was not able to fertilize completely. Uninfected egg in the gonad contaminated by the parasite could be able to fertilize but showed an abnormal development till D-shaped larva and then, died of necrosis after D-shaped larva. And some larva developed from low lipid content egg could not develop to the spat and died after the early umbo stage. The predominant bacteria in the oyster larva collected at bad seed collection areas were Pseudomonas sp. and Pseudomonas like bacteria and the occupancy rates were 53.3∼87.1%.

In this study, CuO was introduced on MWCNTs dispersed with Au nanoparticles to improve the glucose sensing capability of electrochemical biosensors. Nano-cluster shaped CuO was synthesized due to the presence of Au nanoparticle, which affects glucose sensing performance. The biosensor featuring CuO/Au@MWCNTs nanocomposite as an electrode material when 0.1 mole of CuO was synthesized showed the highest sensitivity of 504.1 μA mM(-1) cm(-2), which is 4 times better than that of MWCNTs based biosensors. In addition, it shows a wider linear range from 0 to 10 mM and lower limit of detection (LOD) of 0.008 mM. These results demonstrate that CuO/Au@MWCNTs nanocomposite sensors are superior to other CuO based biosensors which are attributed that the nano-cluster shaped CuO is favorable for the electrochemical reaction with glucose molecules.

그래핀 옥사이드가 탄소나노튜브기반 바이오센서 전극의 포도당 산화효소 담지능 및 민감도에 미치는 영향

To improve both the GOD immobilization capability and sensitivity of MWCNTs-based biosensor electrode, the electrode was prepared by adding different quantities of GO. The addition of GO increased hydrophilicity and the surface free energy of electrodes for glucose sensing as well as the dispersion of MWCNTs. In addition, the GOD immobilization capability was enhanced and the sensitivity was improved up to 121 μA mM-1 even though having a high Km value (0.105) when adding 0.05 g GO to 0.05 g MWCNTs. These experimental results were attributed to the fact that the improvement in dispersion stability for MWCNTs, hydrophilicity, and surface free energy of electrode surface due to the addition of GO affected GOD immobilization capability.

For the purpose of reproduction of traditional gold thread, the artifact investigation was organized for 70 cases (109 pieces) of relics from Korea, China and Japan. In most cases, the main backside material of gold thread from Korea was the bast fibers from paper mulberry. In this study, the optimum sheet-making of Hanji for gold thread reproduction was tried by controlling several process factors of Hanji such as the cooking and beating time of paper mulberry fibers, the number of sheet-making ply, and converting method (Dochim). Tensile index, folding endurance and compressive strength of Hanji showed differences according to the correlation between cooking and beating time, and application of converting method (Dochim), while bending stiffness fell with decrease of thickness. These results can be applied to consider manufacturing factors to make Hanji for the production of gold thread.

To determine whether the seaweed Saccharina japonica can effectively utilize dissolved nutrients from Sebastes schlegeli fish cultures, a laboratory experiment was conducted in a static system for 7 days at ESFRI, NFRDI in Korea. The experiment included an S. schlegeli monoculture system and an S. schlegeli-S. japonica IMTA system. Saccharina schlegeli density (415±24 g; mean±SE) remained the same in all treatments, whereas seaweed density varied across treatments of 0, 0.5, 1, 2, and 3 kg (control and T1-T4, respectively). During the experiment, nutrient (NH4+ and PO4(3-)) concentrations were measured at 24-h intervals. NH4+ concentration of the control group increased from 0.117±0.021 mg/L at the start of experiment to 5.836±0.904 mg/L at the end of experiment. NH4+ concentrations of each treatment were 3.004±0.040, 2.086±0.133, 1.642±0.121 and 0.775±0.007 mg/L in T1, T2, T3, and T4, respectively, at the end of experiment. The concentration of PO4(3-) exhibited a similar trend to NH4+ concentration. NH4+ and PO4(3-) concentrations significantly decreased with increased S. japonica thallus density each day (P<0.05). The nutrient removal efficiency (NRE) and nutrient uptake rate (NUR) showed different relationships with changes in thallus density; NRE increased but NUR decreased as thallus density increased. Based on measured concentrations of NH4+ and S. japanica weight, regression analysis defined the relationship between as an exponential function, Y=3.8165e(-0.505X) (R2=0.9552). Our results demonstrated that S. japanica can function as an efficient component in IMTA with environmental and potentially economic benefits for fish hatcheries.
