A capacitance-type sensor using porous silicon layer was developed to measure aqueous alcohol concentration. Since alcohol, so called ethanol, is very permeable into the silicon wafer, it is often used to help chemical reaction when the silicon wafer is processed under some aqueous solution. In this work, the sensing property was measured for the alcohol concentration from zero to near 100 percent with two types of samples with porous silicon layer formed in 25 and 35% HF solution, respectively. Good reliability as well asw fast response time and good linearity were shown over 10㎑, and the measured capacitance was observed to be inverse to alcohol concentration due to the decrease of the whole dielectric constant in porous silicon layer.

Based on the above statements, we can conclude the sanitary though and physical activities in terms of physical education as follow ; 1. Many sacrificial rites were performed for a good health, happiness and the treatment of diseases on the basis of polytheism in those days. Three Kingdoms accepted the Buddhism as their national religion, by which they wished for longevity and good health. They also realized the viewpoint of their future, their life and death by sutra-chanting and praying. 2. Such sports as achery, Tuho(a game of throwing arrow into the jar), ball-kicking, Ssirum(Korean style wrestling), shooting on horseback, animal hunting, Chucheon(a rope swing) Jeopo(the Four-Stick Game;yuch), Baduk(Korean checkers), Aksak(dice play), Jukma(stilts), kiteflying were performed in order to defend the country, extend the territory and rule the citizens as a means of military exercise. 3. Therefore, it is concluded that in those days military arts and physical activities were based on the cultivation of the harmonious human being not only intellectually, emotionally but also socially, politically, religiously and militarily, which became the basis of the modern physical education.

질산용액에서 Nitroaniline 류에 의한 Al-brass의 부식억제에 관한 연구

주석복,김면섭,이성하 漢陽大學校 環境科學硏究所 1992 環境科學論文集 Vol.13 No.-

0.1M 질산용액에서 nitroaniline류에 의한 Al-brass의 부식억제에 대하여 무게감량 실험, 분극실험, SEM사진 분석 등을 행하였다. Al-brass의 부식속도는 부식계의 온도와 억제제의 농도 그리고 부식억제제의 형태 등에 의존한다. 무게갈량실험과 분극실험을 통해 알아낸 부식억제 효율은 2-nitroaniline>3-nitroaniline>4-nitroaniline의 순이었다. 분극실험의 결과로부터 억제제의 농도가 증가할수록 부식전위는 noble한 방향으로 이동하며 양극 Rafel slope는 일정한 반면 음극 Tafel slope는 증가하여 전류밀도를 감소시키는 것으로 보아 억제제인 nitroaniline는 Al-brass의 음극반응을 억제하는 것을 알 수 있었다. SEM사진 분석에서는 Al-brass의 표면상태를 확인함으로써 각 억제제가 부식반응을 상당히 억제하고 있음을 알 수 있었다. 또한, Flory-Huggins adsorption isotherm의 도입으로 구한 열역학적 특성치로부터 억제제의 흡착형태 등을 알 수 있었다. The inhibition effect of nitroanilines of corrosion of Al-brass in 0.1M nitric acid has been studied by weight loss measurement, polarization method and scanning electron microphotographs. Corrosion rate of Al-brass was depended on concentration of inhibitor and and temperature. The order of inhibitor efficiency according to the position of the substitued group was 2-nitroaniline>3-nitroaniline>4-nitroaniline. The results obtained from weight loss measurements were agreed to those obtaind from polarization studies. Thermodynamic parameters obtained form Flory-Huggins adsorption isotherm showed strong interaction between inhibitor molecules and Al-brass surface.

글룩의 오페라 개혁 이전의 프랑스, 독일, 영국 오페라의 사적고찰(17∼18세기)

Opera which wart generated at Firenze, Italy, at the clone of 16c was spread across the whole of Europe in all directions, and it went on extending throngh France, Germany, and England. By the way, among these three countries that imported Italian opera, the most aucesaful country was France. France which imported opera at the middle of 17c made good use of their Ballot, so they bad come to make Italian opera that is the national opera. This opera has the originality and individuality at the beginning of 18c in accordance with a sort of French temper. R. Cambert, J. B. Lully. A. Campra. J. P. Rameau and etc can be said to be the representative composers of French opera of 17∼18c. R. Cambert was the founder of French opera, and he had been holding the right to a monopoly of French opera performances until J.B, Lnlly's appearance. J. B. Lully con be considered as the man who made opera take ell a French style. He came from Firenze, Italy, and was naturalized in France. He left many works and achievements under Louis's XIV love and care cooperating with the literary man Molie´re and the poet P. Quinault. A. Campra was famous as an early opera composer of France after J. B Lully, and an another conspicuous man was J. P. Rameau. He was the composer who succeeded French opera after J. B Lully rind left the largest achievements as a composer. He left immortal traces as opera composer and musical theorist, also. At the time of Bouffon's Quarrel, he was the man who continued to support the value of French music and opera by safeguarding French opera and was one of the moat famous compasers at the time of the late Baroque music. On the one hand, there was Singspiel which had been called a musical in Germany, but it could not be regarded as an opera. Though Germany imported opera earlier from Italy than France and England, because they didn't use the opera style originally, the development. of German opera had fellen behind. Italian opera had been extended across the whole of Germany from about 1618, Germany played a role as a branch office of Italian opera, so German opera composers could'nt succeed in life unless they composed opera to Italian styles. But, only the Diatrict of Hamburg had gotten out of the influences of Italian opera, and the national music sect of Germany was generated under free sovereign power of that district from 1678, so we came to call this the Hamburg music sect. But about 60 years later even Hamburg was with drawn because of the power of Itaiian opera from about 1738, so German opera had. gradually disappeared. After that, they had to wait far Mozart's appearance in order to get their own real German opera. H. Schiitz who is known ns the founder of German opera can be regarded as the representative opera composer of Germany and we can suppose that R. Keiser, J. Matteson and etc fire the representatives of Hamburg music sect. At the clave of loc in English opera, though there was a light musical combined with dance and play, because this had use to be performed at oxy the Royal-Court by a part of the aristocracy, it was not thought of opera. At the beginning of 17c this Came to appeal on open stage from about 1635, and had been called "Masque". A myth or an allegorical character was its contents. Because opera was developed γacidly In 1655 after the restoration of Imperial regime of Charles II, opera had been imported from France. It can be said that the representative composers of English opera are P. Humphrey, M. Lock. J. Blow, and H. Purcell. Among them, H. Purcell was the cost conspicuous composer who left immense achievements on English music and the history of opera. There is "Dido and Apneas" as his masterpiece that is opera on a small scale style. This skillfully expressed. a transparent color sense of rich Ballet music and dramatic power of expression. He is the first and last man who was thought to composer of a full-length English opera, at came time in spite of his short life of 36 years, he left many achievements in musical history.

The characteristics of H₂ production from livestock wastewater were investigated through an anaerobic acid forming process using Clostridium beijerinckii and the photosynthetic process using Rhodobacter sphaeroides. The submerged separation membrane was installed in the acid forming reactor. The photosynthetic process is composed of two reactors(photosynthetic reactor 1 and photosynthetic reactor 2) which is connected continually. The removal rate of COD and the production of volatile fatty acid(VFA) in the acid forming process were approximately 50% and 1000㎎/ L, respectively. The 70% of COD in the effluent of acid forming process was removed through the photosynthetic process. The production of H₂ in the photosynthetic reactor 1 and 2 was 50 and 25mLH₂/gVFA_(COD), respectively. The values of Y in acid forming reactor, photosynthetic reactor 1 and 2 was 0.2263, 0.0601 and 0.0393, respectively. The acetic acid and butyric acid produced in acid forming process were converted to H₂ by photosynthetic bacteria.

It is important to control resolution for maintenance of good image quality in fluoroscopic unit. This study is to analyze current situation on control of image quality in fluoroscopic unit. Between the sixth and the twenty eighth March 2003, 77 fluoroscopic units in 40 hospitals in Seoul and Kyung-gi area were tested with fluoroscopic phantom(CDRH phantom, Nuclear associates, USA) and image quality test tool including hight contrast resolution patterns and low contrast objects. We exposed radiation in condition of colon study, and then counted the number of patterns on monitor, printed spot film, and printed abdominal film. In the test on monitor, suitable unit within standard number in hight contrast and low contrast test were 68(88%), 49(64%), respectively, and in the test on printed spot film 73(95%), 67(87%), respectively. The cases within standard number in hight contrast and low contrast test on all the two monitor and printed spot film were 44(57%), 65(84%), respectively. Thradiation was exposed from 100 to 120Kvp in fluoroscopy, and spot radiography 80 to 110Kvp mainly. In conclusion, it is necessary that image quality control is done continuously by standard of image quality control suitable for current situation.

In speaker identification systems, it was proved in previous other experimental theses that the performance of GMM is better than that of any other speaker modeling techniques. The EM algorithm is used to build a GMM-based speaker identification system. This paper introduces the modified EM algorithm to enhance the identification rate. The experiments examine algorithmic issues (initialization, variance limiting and model order selection). As a result of the experiments, the modified EM algorithm achieves 95.044% identification accuracy comparing with basic EM algorithm (94.605% identification accuracy) and is shown to outperform the basic EM algorithm.
