The Genus Martensia Hering (Delesseriaceae, Rhodophyta) with M. albida sp. nov. and M. flammifolia sp. nov. on Jeju Island, Korea

이용필,Lee, Yong-Pil The Korean Society of Phycology 2006 ALGAE Vol.21 No.1

The genus Martensia (Delesseriaceae, Rhodophyta) is characterized by thalli composed of one to several blades that consist of proximal membranous sections and distal latticework. Nerves or veins are absent in the membranous sections. The life cycle of Martensia is accomplished by isomorphic alternation of generations. The gametophytes of Martensia are dioecious, and the male and female gametangial plants are morphologically similar. The type species of Martensia is M. elegans Hering. In this study, nine species were confirmed to occur in the subtidal regions of Jeju Island, Korea: M. albida sp. nov., M. australis Harvey, M. bibarii Y. Lee, M. elegans Hering, M. flammifolia sp. nov, M. fragilis Harvey, M. jejuensis Y. Lee, M. palmata Y. Lee, and M. projecta Y. Lee. Three of these, M. australis, M. fragilis, and M. elegans, are new records in the flora of Korea. The results of molecular analyses of the internal transcribed spacer (ITS) 1 region in the nrDNA showed that M. elegans is identical to M. australis, and M. fragilis coincides with M. bibarii. It may be a less effective tool for the species discrimination in Martensia.

In recent years, gonorrhea has been pandemic and remains one of the most common STDs in the world, especially in developing countries. For the detection of a more effective therapeutic regimen and assessing the prevalence of Penicillinase Producing Neisseria gonorrhoeae(PPNG), we have been trying to study the patients who have visited the Venereal Disease Clinic of Choong-Ku Public Health Center in Seoul since 1980 by menas of the chromogenic cephalosporin method. In 1998, 93 strians of N. genorrhoeae were isolated, among which 60(64.5%) were PPNG. The prevalence of PPNG in Seoul, which had been decreased to 39% in 1996 after a peak of 74.3% in 1993, is increased to 64.5% in 1998.

이정우,박형서,박용규,노상필,이유선,정승현,김보영,이재환,최시완,정진옥,성인환 충남대학교 의과대학 의학연구소 2003 충남의대잡지 Vol.30 No.1

목적 : 관상동맥의 경련에 의한 이형성 협심증환자에 있어서 운동부하 심전도 검사의 결과는 매우 다양하다. 이에 저자들은 충남대학교병원 순환기내과에서 관상동맥조영술상 이형성 협심증으로 확진된 환자를 대상으로 운동부하 심전도 검사를 시행하여 이에 대한 결과를 연구하였다. 방법 : 1995년 1월부터 2002년 3월까지 흉통을 주소로 충남대학교병원 순환기 내과에 입원하여 관상동맥조영술을 시행하여 관상동맥의 내경이 50% 미만의 협착이 있고, 에르고노빈(ergonovine) 유발검사도 이형성 협심증으로 진단을 받은 233명중 운동부하 심전도 검사를 시행 받은 183명의 환자를 연구 대상으로 하였다. 운동부하 심전도 검사 결과의 판독시 발생할 수 있는 오류를 줄이기 위해서 운동부하 심전도 검사를 시행하기전 심전도상 ST분절의 상승(5예)이나 하강(8예)이 있는 경우 EH한 T파의 역위(19예)가 있는 32명의 환자를 제외한 총 151명의 환자를 대상으로 하였다. 운동부하는 Marquette사의 case 15 답차를 이용하였고, Bruce protocol에 따라 증상이 나타날 때까지 최대로 실시하였으며 각 stage 및 운동후의 혈압을 측정하고 12 유도 심전도를 기록하였다. 결과 : 1) 임상적 특성 - 내원시 임상 상은 안정형 협심증이 39예(25.8%), 불안정형 협심증이 103예(68.2%), 심근경색증이 9예(6.0%)이었다. 운동부하 심전도 검사 결과 양성 군과 음성군간에 있어서 당뇨병, 고혈압, 비만도, 총 혈청콜레스테롤치, 현재의 흡연 여부, 병력상 운동시 흉통의 유무, 내원시 임상적 진단, 협착의 정도, 연축의 수 등을 조사하였는 바 어떠한 인자들도 유의한 차이를 발견할 수 없었다. 2) 운동부하 심전도 검사 - 운동부하 심전도 검사를 시행 받은 151명의 환자중 음성인 경우는 134예(88.8%)이었고, 양성인 경우는 17예(11.2%)이었다. 양성 소견을 보인 환자들중 ST 분절의 상승이 4예(2.6%), ST 분절의 하강이 13예(8.6%)이었다. 3) 관상동맥조영술 - 관상동맥조영술상에서 혈관 경력 위치는 우관상동맥이 70예(46.1%), 좌전하동맥이 44예(28.9%), 좌회선동맥이 17예(11.2%)의 순으로 나타났다. 운동부하 심전도 검사상 ST 분절의 상승이 있었던 예중 Ⅱ, Ⅲ, aVF에서 ST 분절의 상승이 있었던 1예는 관상 동맥조영술상 우관상동맥에서 경련이 발생하였고, V2-V4에서 ST 분절의 상승이 있었던 2예중 관상동맥조영술상에도 좌전하행동맥에서 경련이 나타난 예는 1예이었으며 다른 1예는 좌회선동맥에서 경련이 나타났고, V5-V6에서 ST 분절의 상승이 있었던 1예는 관상동맥조영술상에도 좌회선동맥에서 경련이 나타났다. 운동부하 심전도 검사상 V5 또는 V6에서 ST 분절의 하강이 있엇던 13예중 6예(46.1%)는 관상동맥조영술상 우관상동맥에서 경련이 발생하였고, 3예(23.1%)는 좌전하행동맥에서, 1예(7.7%)는 좌회선동맥에서, 나머지 3예(23.1%)는 2개의 혈관이나 기타 분지에서 경련이 발생하였다. 결론 : 1) 이형성 협심증 환자는 운동부하 심전도 검사에서 11.2%의 양성소견을 보였다. 이중 ST 분절의 상승은 2.6%이었고, ST 분절의 하강은 8.6%이었다. 2) 이형성 환자중 운동부하 심전도 검사를 실시하여 음성을 보이는 경우 다혈관 관상동맥질환이기 보다는 이형성 협심증일 가능성이 더 높다고 예측할 수 있을 것으로 생각된다. 3) 이형성 협심증 환자중 운동부하 심전도 검사를 실시하여 ST 분절의 상승을 보이는 경우 다혈관 관상동맥질환이기 보다는 이형성 협심증일 가능성이 더 높다고 예측할 수 있을 것으로 생각된다. 4) 운동부하 심전도 검사 결과에 대한 당뇨병, 고혈압, 비만도, 총 혈청콜레스테롤치, 현재의 흡연여부, 병력상 운동시 흉통의 유무, 내원시 임상적 진단, 협착의 정도 등 어떠한 인자들도 3그룹(ST 분절의 상승, ST 분절의 하강, 음성)간에 유의한 차이를 발견할 수 없었다. 5) ST 분절의 상승 부위와 관상동맥조영술상 관상동맥의 연축이 일어나는 혈관과의 상관관계는 매우 높았다. No reports in the literature describe the results of exercise testings in a large number of patients with pure variant angina(coronary stenosis <50%) in Korea. In this report, We present the results of treadmil exercise testing in 151 patients with variant angina. 151 patients with angiographically proven coronary artery spasm underwent a treadmil exercise test. The clinical characteristics of variant angina patients classified according to ST-segment response to exercise were analyzed. Of 151 patients underwent a treadmil exercise test, negative result was seen in 134 patients(88.8%) and positive result was in 17 patients(11.2%). Of 17 patients saw positive result, exercise-induced ST segment elevation was present in 4 patients(2.6%) and ST segment depression was seen in 13 patients(8.6%). There was not a significant relationship between the ST segment response to exercise and the clinical variables(diabetes, hypertension, obesity, total cholesterol, current smoking, effort angina, clinical diagnosis, and degree of stenosis) assessed. Of 4 patients with ST segment elevation in treadmil exercise test, 1 patient with ST segment elevation in Ⅰ,Ⅲ,aVF had spasm in right coronary artery(100%) on coronary angiography, of 2 patients in V2-V4 had spasm in left anterior descending coronary artery in 1 patient(50%) and 1 patient in V5-V6 had spasm in left circumflex artery(100%). Positive treadmil exercise test was present in 11.2% of variant angina patient. If we have negative treadmil exercise result in patients with clinical manifestation of unstable angina at admission, we may have a suspicion of variant angina rather than multi-vessel disease. If we have exercise-induced ST segment elevation in patients with clinical manifestation of unstable angina at admission, we have a suspicion of variant angina rather than multi-vessel disease. Our result suggests that the correlation between the site of the ST segment elevation and the artery involved is quite good.

이우선,최권우,고필주,서용진 조선대학교 에너지.자원신기술연구소 2003 에너지·자원신기술연구소 논문지 Vol.25 No.1

As the integrated circuit device shrinks to the smaller dimension, the chemical mechanical polishing (CMP) process was required for the global planarization of inter-metal dielectric (IMD) layer with free-defect. However, as the IMD layer gets thinner, micro-scratches are becoming as major defects. Micro-scratches are generated by agglomerated slurry, solidified and attached slurry in pipe line of slurry supply system. It is well known that the presence of hard and larger size particles in the CMP slurries increases the defect density and surface roughness of the polished wafers. In this paper, we have studied aging effect the of CMP slurry as a function of particle size. We prepared and compared the self-developed silica slurry by adding of abrasives before and after annealing. As our preliminary experiment results, we could be obtained the relatively stable slurry characteristics comparable to original silica slurry in the slurry aging effect.

이명희,최해술,서용필,김철환 成均館大學校 科學技術硏究所 1995 論文集 Vol.46 No.2

This paper presents a new distance relay modeling techniques which avoids unnecessary computational procedure. A general-purpose simulation language, called MODELS, has been added to the software ATP(Alternative Transients Program) providing a new option to perform numerical and logical manipulations of variables of an electrical system. This language has been designed to replace the previous option TACS(Transient Analysis of Control Systems) which permits to simulate a control system in conjunction with a large power network. One purpose of this study is to build a structure for modeling of digital distance relays within EMTP MODELS. Contrary to the traditional methods, the new method using MODELS reduce the number of simulation steps in modeling the distance relay.

이재구,이용필,안기창,김일근,채홍민 충북대학교 첨단원예기술개발연구센터 2000 연구보고서 Vol.5 No.-

일반 생활환경 또는 원예시설 내의 공기오염물질중 하나인 잔류 농약 및 병원성 미생물을 제거하기 위한 방법으로 자연광 또는 인공광 조건에서 몇 가지의 감광제/광촉매에 의한 광분해 촉진효과와 미생물 살균효과 시험을 수행하였다. 감광제로는 quinone계 물질 PS-1, aromatic ketone계 PS-2, aromatic amine계 PS-3, organic acid salt의 PS-4, inorganic compound의 PC-1, inorganic metal compound의 PC-2와 PC3를 선발하여 사용하였다. 그리고 시험 농약으로 시설내 병해충 방제농약인 살충제 carbofuran, 살균제인 diethofencarb, metalaxyl, benomyl, thiram, propineb, iprovalicarb를 선정하였고, 유해 미생물로는 5종의 곰팡이와 3종의 세균성 식물 병원균들을 선정하였다. 농약의 광분해 촉진효과로는 대체적으로 PS-1, PS-2, PS-3, 그리고 PC-2에서 감광제/광촉매를 처리하지 않은 처리구에 비해 높은 분해율을 보였다. 미생물 현탁액에서는 광촉매에 의한 곰팡이의 살균효과는 없었으나 병원성 세균의 성장은 광촉매에 의한 저해가 뚜렷하였다. 위의 결과에서 볼 때 광조건하에서 감광제/광촉매의 사용은 농작물이나 또는 토양표면에 잔류하는 농약의 광분해나 병원성 미생물을 제거하여 보다 안전한 농산물을 생산함은 물론 토양을 위시한 주변환경중의 농약잔류물을 경감시킴으로서 환경보호 및 재배시설내의 작업자와 일반대중의 건강 증진에 커다란 도움이 되리라 기대된다. For the artificial removal of pesticide residues and pathogenic microorganisms in the greenhouse or in the living environment, the accelerated photodegradation and the biocidal effects by some photosensitizers(PS)/photocatalysts(PC) were tested under the sunlight or artificial light. The test pesticides included thiram, diethofencarb, propineb, benomyl, metalaxyl, and iprovalicarb as fungicides, carbofuran as an insecticide, and some bacteria and fungi as the pathogenic microorganisms. PS-1, PS-2, and PC-1 led to the accelerated photodegradation of all the tested pesticides compared to the control without PS/PC under the sunlight. The photocatalysts had no effect on the growth of the fungi in aqueous suspension. Whereas, the PC-2 and PC-3 added to the bacterial suspensions obviously inhibited the microbial growth under the artificial light. These results suggest that the photosensitizers/photocatalysts in the presence of light can decrease some pollutants in the facility environment and hence they can be used to reduce the exposure of the workers in the environment to the harmful pollutants. Key words: Photosensitizer, photocatalyst, photodegradation, pesticide, biocide, bacteria, fungi

大邱市內에 있어서의 山羊 및 緬羊의 結核症에 對한 調査

孫濟英,金容珌,李學喆 慶北大學校 1962 論文集 Vol.5 No.-

Tuberculosis is rare in sheep and goats. In sheep most of the infection that have been typed in the United States were found to be of the avian-type, but in orther countries most have proved to be of the bovine-type. The data on tuberculosis in goats are very meager, so this fact gives an impression on us that goats are relatively resistant to infection. Infections, however, with human-type, bovine-type and aviane-type have been rarely reported. The obtained specimens (lung, liver, spleen) from a died goat at Taegu Agriculture and Forestry High school in March 1960 were examined bacteriologically and pathologically to diagnose the cause of its death. Moreover, the 10 sheep and 13 goats which had been together in the same pen with the died goat and the 11 sheep and 202 goats which had been fed in the surrounding area of Taegu city were tested on the tuberculin reaction with the intradermal method. The tuberculin was mamalian type (O.T.). The results thus obtained would be outlined as follows: 1. The death of the goat at above school was caused with a generalized tuberculosis infected through respiratory route by the bovine-type of tubercle bacilli. 2. The result of tuberculin test have proved that among 10 sheep and 13 goats which were fed together with the died goat, the positive reaction was found in 2 sheep (20%) and 2 goats (about 15.4%) and the doubtful reaction was found in 1 sheep (10%) and 2 goats (about 15.4%), but among 11 sheep and 202 goats which were fed in the surrounding area of Taegu city, the positive and doubtful reaction were found in 2 goats (about 1%) and 3 goats (about 1.5%) respectively, and all of the sheep reacted in the negative.

Background: The purpose of this study was to determine that the assessment of serum neuron specific enolase(NSE) could provide a reliable early predictor of neurologic outcome after cardiac arrest. Methods: Prospective, observational study was performed from April 1996 to March 1998 at a university teaching hospital ED. Serum NSE concentrations were analysed twice at 24 and 48 hours after return of spontaneous circulation(ROSC). Neurologic outcome was categorized using cerebral performance category(CPC). Results: Twenty-nine patients(16 were men) were enrolled during the study period. The mean age was 50.8 years. Nine(31%) of them showed good outcome defined as CPC 1-3, and 20(69%) patients showed bad outcome defined as CPC 4-5. In the good outcome group, the serum NSE was revealed 33.8±9.3 ng/ml at 24 hours, 34.0±4.73 ng/ml at 48 hours. While in the bad outcome group, it was 99.5±11.7 ng/ml and 114.6±15.8 ng/ml. The NSE at 48hr after ROSC was more prescise than that of 24hr. When the cutoff value of 50 ng/ml at 48hr, the sensitivity was 82%, and specificity was 93%. Conclusion: This study suggest that the serum NSE may represent a valuable, noninvasive, and useful clinical tool for prediction of neurologic outcome after cardiac arrest.
