광합성세균 미생물막반응기에 의한 유기성폐수의 처리특성

오광근,이철우,전영중,이재홍 한국미생물생명공학회 ( 구 한국산업미생물학회 ) 1996 한국미생물·생명공학회지 Vol.24 No.6

홍색비유황 광합성세균인 Rhodopseudomonas capsulata를 선택하여 porous ceramic bead를 충진시킨 충진형 반응기(Packed-bed reactor, PBR)와 분말활성탄을 현탁시킨 유동산 반응기(Fluidized-bed reactor, FBR)에서 미생물막을 형성하여 폐수처리를 비교한 결과 PBR이 FBR보다 BOD 부하량 변화에 더 안정적인 처리성을 보였다. 체류시간 (hydraulic retention time, HRT)에 따른 처리성은 유입폐수 농도를 각각 BOD 10,000, 20,000 mg/ℓ로 하였을 때, HRT 1일 이상에서 90% 이상의 처리효율을 가지며, 유출수의 BOD 농도는 각각 350, 800 mg/ℓ이었다. PBR에서 유입수의 BOD 농도변화에 다른 유출수의 농도를 측정하여 단위부피당 기질부하량 상수 (maximum specific BOD loading rate, P) 및 부착미생물 포화기질 제한농도 상수(half saturation constant, K_6)를 구한 결과, 각각 22.2 gBOD/ℓ·day, 1,750 mgBOD/ℓ이었고, 처리효율 90% 이상을 나타내는 BOD 용적부하(volumetric BOD loading rate)는 20 gBOD/ℓ·day 이상으로 표준활성오니법의 0.6 gBOD/ℓ·day에 비하여 30배가 넘는 값을 나타내었다. An efficient packed-bed type biofilm reactor charged with immobilized phototrophs was developed to treat organic wastewater at an extremely high volumetric loading rate. The packed bed reactor (PBR) charged with porous ceramic beads was superior to a fluidized-bed reactor suspended with activated carbon powders in terms of many aspects such as BOD removal efficiency, operational stability, and overall economics. For wastewater with BOD concentration as high as 20,000 mg/l, the BOD removal efficiency was maintained above 90% when the hydraulic retention time (HRT) was longer than 1 day. The allowable volumetric BOD loading rate of this reactor (20gBOD/l·day) is more than ten-folds higher than that of an ordinary activated sludge method. The behaviour of the reactor was represented well by a Monod type kinetic equation with a maximum specific BOD loading rate(P) of 22.2gBOD/l·day and a half saturation constant(K_s) of 1,750 mgBOD/l.

Objective: We describe various clinical presentations of female urethral meatal stricture, which may mimic other pelvic floor disorders and result in diagnostic delay. Diagnosis, management, and outcome results are reported Materials and Methods: We reviewed retrospectively 26 consecutive cases of female urethral meatal stricture. Patient characteristics, history, clinical presentation, symptom score, maximal flow rate, residual urine, diagnosis, management and short-term follow up are reported. Results: Mean patient age plus or minus standard deviation was 54 years. Most 21 (81%) cases were referred as diagnostic dilemmas with symptoms present for 1 month to 30 years. Mean interval between onset of symptoms to diagnosis was 5.8 years. The most common symptoms were residual urine sensation (77% of cases), frequency (54%), pelvic pain (46%), dysuria (46%), weak stream urine (27%), urgency (15%) and 17 patients (65%) have combined symptoms. 16 patients (62%) had been treated with oral and/or vaginal medication and/or psychotherapy. The female urethral meatal stricture was visible on physical examination in 21 patients (81%) and cystoscopy in 5 patients (19%). Of these visible urethral meatal stricture, 11 patients (45%) contained recurrent urinary tract infection, 9 patients (35%) contained urethral mucosal prolapse, 7 patients (27%) contained urethral diverticulum, and 3 patients (12%) contained stress urinary incontinence. 18 patients (69%) who has been treated with oral and/or vaginal medication or psychotherapy was not successfully improved. Treatment consist of urethral meatal excision and/or everted urethral mucosal excision and/or urethral diverticulum excision and/or anti-incontinence surgery when indicated. Subsequently 24 patients (92%) had improved symptom score, but 2 patient was not changed. In 9 patients new symptom developed. Conclusions: Female urethral meatal stricture have several urinary symptoms and may mimic other pelvic floor disorders. This condition should be considered in women with frequency, residual urine sensation, pelvic pain, dysuria and etc. Medical treatment is not sufficient but surgical treatment is usually simple, safe and effective in alleviation associated symptoms.

In this paper, the simulator or WLAN system modem based on IEEE 802.11a is implemented. The performance of WLAN modem in the realistic indoor multipath channel models is analyzed, according to frequency offset compensation and channel estimation methods. The previous works for WLAN(Wireless Local Area Network) system based on OFDM(Orthogonal Frequency Division Multiplexing) is mainly individual study for independent frequency offset or symbol synchronization. For the performance evaluation of the WLAN system, indoor Rayleigh multipath channels are adopted, and the BER(Bit Error Rate) of WLAN system based on 1/2 code-rate QAM is calculated. From the simulation results, 2dB difference of Eb/No exists for on BER of 10-3 between the channel compensation case and ideal channel compensation, and zero frequency offset case.

This paper examines the propriety of adopting the faculty systems within the college of humanities and social sciences at Sunchon National University. It also proposes the strategies for the development of the college. Several empiracal evidences were gathered and examined from the other universities which had been running the faculty systems. The prospects of the 21st century´s Kwangyang Bay and the ideas for the college development were reflected in this paper. The results of this paper are summarized as follows ; ㆍBecause of the changes in the educational environment, there are so many kinds of threat which impair current status of Sunchon National University. ㆍAmong other factors which affect the development of college, the most important factors is the constituents´ attitude of mind toward college development. ㆍThere is no need of faculty systems to integrate the departments within the college. Because each department has its´ own characteristic, and it is difficult to find the similarities between departments in terms of curriculum. ㆍThe specialization strategies to support a specific department is not desirable. Because of short history relatively, there isn´t any department which has its´own competitive power. Instead of those strategies, each department should be treated equally until it begins to have its´ own competitive power. ㆍTo enhance a balanced development in the area of humanities, the college should have the departments such as Korean language and literature, English language and literature. ㆍIn order to ensure the high-quality education, the coollege should have several supporting systems that every student will finish with a good command of English and adaptability to field work.

MRC 결합의 레이크 수신기에서 채널 추정 알고리즘의 성능분석

오동진,나철훈 국립7개대학공동논문집간행위원회 2005 공업기술연구 Vol.5 No.-

In this paper, we analyze channel estimation algorithms in a RAKE receiver with MRC. There are 3 popular channel estimation algorithms, which are WMSA(Weighted Multi-Slot Averaging) algorithm, EGE(Equal Gain Estimation) algorithm. and SSE(Symbol-to-Symbol Estimation) algorithm. We analyze asynchronous IMT-2000(3GPP) which employ 3 different channel estimation algorithms by using MATLAB. We used jakes fading channel model for the analysis. From simulation results, we could observe that the performance of WMSA algorithm is better than others in low Doppler effect(3km/h). However, in the case of high Doppler effect(120km/h), the EGE algorithm is more efficient. In this case the simple estimator with EGE algorithm seems to be more useful.

한국인 당뇨병 및 비당뇨병 환자에서의 뇌혈관 질환 유무에 따른 PAI-1 촉진자 유전자형과 인슐린저항성에 관한 연구

오승준,김영설,박철영,김덕윤,김성운,양인명,김진우,최영길,팽정령,정경천 대한비만학회 2000 The Korean journal of obesity Vol.9 No.2

연구배경 : 혈전현상을 특징으로 하는 질환에서는 Plasminogen activator inhibitor-1 (PAI-1) 이 높은 활성도를 보이는데, PAI-1 치는 당뇨병, 심근경색증, 비만 등에서 높다고 밝혀진 바 있다. 또한 당뇨병 환자들의 합병증의 주요한 병인은 죽상경화증으로 혈전현상이 특징인 질환에서 증가하는 PAI-1이 당뇨병 환자에서 높다. 목적 : 정상인에서의 PAI-1 유전자 촉진자의 유전자형의 분포 및 혈액농도를 관찰하고, 당뇨병 및 뇌혈관 질환 환자군에서의 PAI-1 유전자 촉진자 유전자형의 분포 및 혈액농도를 측정하여 정상인과 차이점을 알아본다. 당뇨병 환자군에서의 혈장 PAI-1 치와 인슐린 저항성, 전구 인슐린 등과의 상관관계를 살펴보고, 인슐린저항성과 대혈관질환의 지표로 사용될 수 있는지 알아보았다. 방법 : 대상으로는 정상인 76명, 제2형 당뇨병 환자 56명, 뇌혈관질환이 동반된 제2형 당뇨병 환자 48명, 뇌혈관질환 환자 51명을 선택하여, 환자의 혈액에서 인슐린, 공복시 혈당, 전구인슐린, 중성지방, 총콜레스테롤 및 기타 생화학 검사 및 이학적 검사를 시행하였다. 환자의 DNA를 채취하여 전사개시 -675bp를 포함하는 대립형질 특이 시발체를 사용하여 중합효소 연쇄 반응을 실시하여, 그 유전자형을 판독하였다. 결과 : 정상 대조군 76명 (46.4±11.1세), 2형 당뇨병 환자 56명 (58.3±12.6세), 뇌경색증 환자 51명 (63.1±13.2세) 대상으로 하였다. PAI-1 촉진자 유전자형의 (4G/4G, 4G/5G, 5G/5G)빈도는 정상 대조군이 각각 23.7%, 75.0%, 1.3%, 뇌경색 환자군이 19.6%, 66.7%, 13.7%, 뇌경색이 동반된 당뇨병 환자군이 33.3%, 58.3%, 8.3% 였다. (X2=12.6, p=0.05). 이러한 사실은 서구인에 비해 4G/4G, 5G/5G 동형 유전자형이 낮은 결과였다. 각 군별 혈장 PAI-1 농도는 정상 대조군 13.4, 1.8 ~ 65.2 ng/mL (중앙값 , 범위 ) 2형 당뇨병 환자군 14.4, 2.9 ~ 47.8 ng/mL, 뇌경색 환자군 21.9, 6.2 ~ 154.7 ng/mL , 뇌경색이 동반된 2형 당뇨병 환자군 28.8, 3.2 ~ 139.3 ng/mL 로 차이를 보였다 (p=0.000). 전체 대상에서 PAI-1 촉진자 부위의 유전자형에 따른 PAI-1 활성도와 항원 농도는 차이를 보이지 않았다. 그러나 PAI-1 활성도는 혈중 중성지방, 전구인슐린, 체질량지수와 독립적인 상관관계를 보였다 (p=0.000, p=0.000 and p=0.005). 결론 : 결론적으로 PAI-1 촉진자 부위의 유전자형은 뇌경색증의 지표는 아니며, PAI-1 활성도를 결정짓는 인자는 유전적 요인보다는 혈중 중성지방, 전구 인슐린, 체질량지수와 같은 대사적 요인으로 생각된다. Plasminogen activator inhibitor-1 (PAI-1) is known be related to insulin resistance and several components of the large vascular disease. Notably, the high frequencies of diseases such as coronary heart disease or stroke are related to type 2 diabetes complications. We studied to find out whether the PAI-1 promother genotype could be a marker for cerebral infarction in type 2 patients. Subject patients were; 56 type 2 diabetics (age 58.3±12.6), 51 patients with cerebral infarction (age 63.1±13.2), 48 type 2 diabetics with cerebral infarction (age 64.8±9.3) , and 76 healthy control (age 46.4±11.1). The 4G/5G genotype of PAI-1 promoter was evaluated by polymerase chain reaction and endonuclease digestion. PAI-1 promoter genotype frequency (4G/4G, 4G/5G, 5G/5G) was 23.7%, 75.0% and 1.3% in healthy control, 17.9%, 67.9% and 14.3% in type 2 diabetes patients, 19.6%, 66.7% and 13.7% in cerebral infarction patients, 33.3%, 58.3% and 8.3% in type 2 diabetics with cerebral infarction (X^2=12.6, p=0.05). This finding is lower in frequency of 5G/5G homozygote than that reported in Caucasians. The plasma PAI-1 concentrations according to the disease were 13.4, 1.8 ~ 65.2 ng/mL (median, range) for healthy control, 14.4, 2.9 ~ 47.8 ng/mL for type 2 diabetes, 21.9 6.2 ~ 154.7 ng/mL for cerebral infarction , and 28.8, 3.2 ~ 139.3 ng/mL, for cerebral infarction with type 2 diabetes (p=0.000). In the all subjects, PAI-1 concentration and activity of PAI-1 promoter genotype did not show any significant difference. However, the PAI-1 activity was independently associated with serum triglyceride level, plasma proinsulin and BMI (p=0.000, p=0.000 and p=0.005 respectively). We concluded that PAI-1 genotype is not a marker for the cerebral infarction ; however, the genotype is related to PAI-1 concentration , and therefore it seems to be that metabolic factors such as triglyceride level or plasma proinsulin or BMI are more in relations with determining the PAI-1 concentration than the genotype.

Theory Building in Knowledge Utilization : A Review

오철호 한국정보사회진흥원 2004 정보화정책 Vol.11 No.2

Despite voluminous studies on knowledge utilization, the extant research provides little support for claims that particular variables affect the use of knowledge in decisive ways. This research effort has been made more complicated recently by the changing contexts of knowledge utilization. In particular, the knowledge utilization field gives remarkably little attention to the systematic accumulation of knowledge from research studies. The purpose of this study is to critically examine studies from the 1990s and to see how they cope with key issues in the field. This study specifically focuses on the question: What conceptual and empirical work has been done in the area of knowledge utilization over the past ten years? An in-depth analysis of research studies shows that the studies done in the 1990s made little conceptual and empirical advancement. In general, these studies seem to walk one step away from infancy in terms of theory building efforts and the empirical orientation of research analysis. They, however, need to improve the rigor in theory building in terms of integrating partial theories or conceptual constructs. This study also suggests a set of ways for improving the efforts of theory building.

The purpose of this study was to examine the effects of the command teaching mehtod and problem solving teaching method by Mosston in achieving the serve, pass and volley skills of volleyball. The subjects of this study were 100 middle school boys and girls students divided into 4 classes. Two classes were taught volleyball skills by using the command teaching method and the others were taught by using the problem solving teaching method. All groups took experimental treatment 3 hours a week for 6 weeks. The subjects were pre-tested before they got experimental treatment. After 6 weeks of teaching the test of serve pass and volley skills applied AAHPERD(1969) were taken to the subjects. The experimentation of this study was based on based on 2(teaching method) X 2(sex) X 2(enforcement). The data analysis was practised by index of trinity dispersion. On the basis of the results compared and analyzed by the pre and post-test, the conclusions were drawn as follows. 1. In achieving the serve skills. there were significant differences between boy-groups and girl-groups but less differences between problem solving teaching method and command teaching method 2. In achieving the pass skills. problem solving teaching method was more effective, especially in boy-groups than command teaching method. 3. But. in achieving the volley skills. it showed no siginificant differences between boys and girls groups, problem solving and command teaching method

태권도 수련이 초등학생들의 정서, 사회성 및 생활태도에 미치는 영향

The effect of TKD practice upon the sentiment and social manner of elementary school children was researched and the formation period of it was analyzed. To prove that the effect of TKD pratice has educationally much effective of forming the whole man it was made an object of this study that they are made up of 836 children and their 90 parents of elementary school. 4.5.6th grade among apprentices in drill halls of cheju-do was investigated and analyzed. So the following results were conculded. 1. The children and their parents think that in the change of sentiment through TKD practice. TKD practice of one year or more has more effective of improving the general standard of sentimemts of patience.brighness. self - confidence. reduction of a feeling of uneasiness, spiritual strength , control ability of feelings. concentration, etc. than that of three months below or to twelve months. 2. On the change of sociality by TKD practice all the students and their parents think that TKD practice of one year or more has more effective of improving the general standard of sociality of cooperation. sense of responsibility equality. independeuce. faithfulness, friendship, etc than that of three months below or four to twelve months. 3. On the change of manner of living by TKD practice their parents think that TKD practice of one year or more has more effective of elevating manner of living than that of three months below or four to twelve months. 4. Most of their parents agreed that they made their children practice TKD to have great confidence in themselves. By forming the above we can conclude following. For the high development of the change of sentiment, sociality, manner of living through TKD practice it is needed for children to train for more than one year. As most of the elementary school children have grown in the stream of overprotection, not feeling difficulty. they need the course of study for self - denial. including patience, staying power. Their parents make their children practice TKD to elevate spirit and have great confidence in themselves. So the apprentices from elementary school must realize that they can change their mind and behavior as better persons, developing their mind and body together only after they don't give up practicing TKD halfway but should practice TKD for more than one year with patience. And the readers of TKD should develop scientific and logical TKD practice programs, having the sense of mission that they charge themselves with part of education for the whole man in the course of school education.
