The protective relaying setting job which has been performed manually, takes a long time and is vulnerable to errors. The goal of this paper is to develop the user-friendly interface for integrated protection system environment and to control protection-related jobs and the database management system efficiently and conveniently.

We intended to know that the result of color duplex ultrasonography corresponded to that nocturnal penile tumescence rigidity in the diagnosis of erctile dysfunction. We performed both color duplex ultrasonography and nocturnal penile tumescence rigidity in 15 erectile dysfunction men. Colr duplex ultrasonography was done with a 7 MHz. color Doppler unit after intracorporeal pharmacological injection and measured maximal arterail diameter, peak systolic velocity, end-diastolic velocity and the results were compared with rigidity and tumescence in nocturnal penile tumescence rigidity using RigiScan. The positive predictive value, negative predictive value, sensitivity, specificity, overall accuracy of color duplex ultrasonography was reasonable when the result of color duplex ultrasonography was compared with the that of nocturnal penile tumescence rigidity. According to this results, color duplex ultrasonography could not only predict but also correspond to nocturnal penile tumescence. Therefore, we suggest that color duplex ultrasonography can relpace nocturnal penile tumescence rigidity if psychogenic and neurogenic erectile dysfunction are distinguished by history and neurologic examination.

Micropenis is defined as a normally formed penis with a size greater than 2 standard deviations below the mean. Twenty three patients with micropenis were managed at Soonchunhyang University Hospital from January 1988 to December 1995 We interviewed and examined them with micropenis to investigate the cause of micropenis, concomitant diseases, the efficacy of treatment and their sexual activity in postpubertal men. The patients were divided into 2 groups: 16 prepubertal and 7 postpubertal men. 9 patients had cryptorchidism, 3 of them were bilateral and 5 patients had hypospadias. Etiology was determined by hormonal assay including HCG stimulation test ; 8 as hypogonadotrophic hypogonadism, 4 as primary testicular dysfunction and 5 as idiopathic. However etiology was undetermined in 6 patients. All patients had endocrine therapy using HCG or depot testosterone. All except 4 cases responded satisfactorily. All postpubertal patients(group 2) were below the 10th percentile. Puberty was delayed in 3 patients in the older group. All patients were heterosexual and they have had erections and orgasms. Five patients have had ejaculations, 3 of them were sexually active and they have experienced vaginal penetration, Nevertheless, their sexual partners have had complaints and the patients themselves have felt ashamed and dissatisfied. Fortunately, they were mentally healthy. None of these patients were married or had a child.

Although ureteroscopy(URS) has been used widely to remove ureteral calculi, there is an argument against the belief that anesthesia or admission is needed for URS. We evaluated the experience of URS without anesthesia in female patients. From September 1997 to July 1998, URS was performed in 31 female patients without anesthesia. EHL(Electrohydraulic Lithotripsy) was used in 21 patients with impacted or large stone over 5mm. All patients were given oral antibiotics for 3 days and follow-up KUB was taken to confirm successful removal of the stone one week after the procedure. Successful treatment was defined as complete removal of the stone or residual fragments less than 2mm. Overall success rate was 96.7%(30 cases among 31 cases). All but one patient tolerated with analgesia through the entire procedures. There were only minimal complications such as mild flank pain and hematuria. So, we recommend that non-anesthetic ureteroscopic removal of stone as the first choice for treatment of lower ureteral stones in female based on the minimal morbidity, high success rate and low cost.
Titanium의 切削에서 Saw-toothed Chip의 切削 Energy에 관한 硏究
吳錫炯,徐南燮 全北大學校 1987 論文集 Vol.29 No.-
In metal cutting, various types of chips are produced. W. Rosenhain classified them into flow-type, shear-type, pluck-off-type and tear-type. In the experiment, Nakayama found the chips whose shapes were saw-toothed-like and which were produced periodically. Since then this type of chip has been called saw-toothed chip. When this chips occur, the cut surface is smooth and the required cutting force is small. Nakayama and Ueda insist that saw-toothed chip is formed by the brittle fracture, the vibration, and etc. They studied about the effect of cutting depth, true rake angle on the slip and pitch. But there has not been report on the cutting energy with saw-toothed chip. This report shows how the depth of cut, true rake angle, and cutting speed effect on the cutting energy in machining titanium. The results are as foolows: 1. The specific cutting force decreases with the increase of the pitch. 2. The normal stress and the shear stress on the shear plane decrease with the increase of cutting depth. They are almost independent on the variation of true rake angle. 3. The unit friction energy on the tool face and the unit shear energy on the shear plane decrease with the increase of true rake angle and cutting depth. 4. The saw-toothed chip is formed in the case that the depth of cut is deeper than 0.03mm, and the smaller the true rake angle is, the larger the range, where saw-toothed chip is formed, is.

Actinomycosis is chronic, granulomatous, suppurative and fibrosing disease caused by Actinomyces. Actinomyces are anaerobic, G(+), non-acid-fast, branched, filamentous bacteria. The most commonly found microorganism is Actinomyces israelii. Common site for isolation of actinomyces are dental plaque, dental caries, calculus, and tonsillar crypt. A breach in the integrity of the mucosa by direct trauma or following a fracture, tooth extraction, root canal therapy or some intraoral surgical procedure is thought to be the most likely portal of entry. This is a case report of 23 years old male with cervicofacial actinomycosis developed after extraction and treated with surgical excision and antibiotics.
