To estimate the penile blood flow changes during artificial with erection intracorporeal papaverine injection, we injected 99 m Technitium-Human Serum Albumin via antecubital vein simultaneously and calculate the radioisotope activity of the penis using computerized Gamma Camera. We classified the results into 3 groups according to the transit time, erection persistent time and venous index in 67 impotence patients. We defined the arteriogenic impotence with the delayed transit time (more than 600 seconds) in 13 patients and venogenic with the shortened erection persistant time (less than 200 seconds) and decreased venous index (less than 0.8) in 11 patients. The rest of them (43 patients) were regarded as equivocal impotence, probably nonvasculogenic or psychogenic.

본 논문에서는, 음성 인식률 향상을 위하여 청각 특성을 기반으로 한 GFCC(gammatone filter frequency cepstrum coefficients) 파라미터를 음성 특징 파라미터로 제안한다. 그리고 전화망을 통해 얻은 고립단어를 대상으로 인식실험을 수행하였다. 성능비교를 위하여 MFCC(mel frequency cepstrum coefficients)와 LPCC(linear predictive cepstrum coefficient)를 사용하여 인식 실험을 하였다. 또한, 각 파라미터에 대하여 전화망의 채널 왜곡 보상기법으로 CMS(cepstral mean subtraction)를 도입한 방법과 적용시키지 않은 방법으로 인식실험을 하였다. 실험 결과로서, GFCC를 사용하여 인식을 수행한 방법이 다른 파라미터를 사용한 방법에 비해 향상된 결과를 얻었다. In this paper, we propose GFCC(gammatone filter frequency cepstrum coefficient) parameter which was based on the auditory characteristic for accomplishing better speech recognition rate. And it is performed the experiment of speech recognition for isolated word acquired from telephone network. For the purpose of comparing GFCC parameter with other parameter, the experiment of speech recognition are carried out using MFCC and LPCC parameter. Also, for each parameter, we are implemented CMS(cepstral mean subtraction)which was applied or not in order to compensate channel distortion in telephone network. Accordingly, we found that the recognition rate using GFCC parameter is better than other parameter in the experimental result.

The clinical efficacies of Korean Red Ginseng for improving sexual function has been reported only by selfreporting questionnaires.AVS-Penogram is a method evaluating natural penile blood flow changes by Gamma-camera after intravenous injection of Techmetium 99m-RBC and also stimulating by erotic video tape. To more objectively evaluate the efficacies of Korean Red Ginseng for erectile function, we applied AVS-Penogram as a objective diagnostic tool. AVS-Penogram studies were done in 28 patients with erectile dysfunction after administration of Red Ginseng(19) or placebo(9) group.The pattern of AVS-Penogram before medication were normal type in 4, impossible in 2, unstable in 20, delayed in 1, and mixed in 1. The unstable type were the most prevalent observed in 71.4% of all patients.The patterns of AVS-penogram were 2. 2. 13. 1 in Red Ginseng group, while in placebo group normal 2, unstable 7. After 4 weeks in Red Ginseng group, there were 3 cases of improved penogram findings, while only 1 in placebo group. There were no statistical significancies in the type of penogram changes on both group.But the maximum radioactivity were improved in 11<br/> patients(57.9%) in Red Ginseng group, while 2(22.2%) in placebo group. There were statistical significancies in comparing the maximal radioactivity of penogram on both group. These AVS-Penogram findings shows, encouraging results of by increased penile blood flow Korean Red Ginseng our medication. Further study is more needed to re-confirm these results by more concentrated active formulations of sapanonin & other active ginsenosides. These promising results will lead to develop a new remedy for erectile dysfunction by Korean Red Ginseng.

There are nine word class in Korean school grammar. That is noun, pronoun, numeral, adverb, determiner, postpositional particle, verb, adjective, interjection. In Korean school grammar, the criteria which is used in determining word class include considerations on forms, functions and meanings. By the way, a word is used more than two word class, that is currency of the word class. However, currency of the word class helps word class education. My argument begins with review about the school curriculum and the studies precedent. secondary, I discuss the currency of the word class. Lastly, I design a lesson on word class education by the heuristics. In this lesson, I intend and hope to advance the grammatical competence of students.

This paper has performed the speech security system which is operated by software program using DTW based text prompt speaker verification algorithm in accordance with 12th gammatone filter frequency cepstrum coefficients for feature parameter. This realized system has operated sequentially as below: Users utter the proposed words, the uttered word is transformed as the feature parameters, the pattern is compared with the already stored reference pattern and could decide the user's availability whether use it or not. This research executed 10 words from 15 speakers as test data for the security system, experimentally. The result showed FA 10.2% and FR 8.84% respectively, which are average errors in the simulated experimental circumstances.

This study was conducted to determine whether patients could engage in sexual activity following total cystectomy with ileal conduit. Sixteen male bladder cancer patients treated by total cystectomy with or without preoperative irradiation. Patients ranged in age from 48 to 70 years (mean 59.6 years). The interval from therapy ranged from 7 to 82 months (mean 33.8 months).Prior to therapy 11 /16 patients (68.8 %) reported they were engaging some form of sexual activity at least once per month. All were able to achieve an erection and were orgasmic. Following total cystectomy, 6 patients (37.5%) continued to engage in sexual activity at least once per month and were experiencing orgasm. 3 patients (18.8%) reported they were able to achieve an erection. The spontaneous resumptiom of sexual activity by almost one third of the patients in this study refutes the assumption that sexual activity would be impossible following total cystectomy.

본 논문은 주파수대역검출센서(FBDS)를 이용하여 전력 케이블에서 부분방전(PD)가 발생했을 때 이것을 검출하고 진단하는 시스템 개발에 관한 논문이다. 주파수대역검출센서는 각 주파수대역에서 발생하는 부분방전을 음향학적으로 변환하여 검출한다. 부분방전은 그 음향학적 신호 형태로 잡음과 유사하다. 따라서 본 논문에서 상대적 레벨교차율(RLCR)과 주파수에너지 스펙트럼을 이용하여 정상과 비정상을 구별하여 부분방전을 검출하였다. This system is a diagnosis system that checks whether it causes a partial discharge of a power cable or not. PD(Partial Discharge) is detected by FBDS(Frequency Band Detection Sensor). That is, it means a acoustic sensor capable of detecting each frequency band. The wave shape of PD sound is similar to noise and is systematically generated by partial discharge. Therefore, in this paper, we could discriminate between normal and abnormal case using relative level crossing rate(RLCR) and spectrogram of frequency energy rate.
