Transurethral resection of the prostate(TURP) is most commonly used in relief of symptoms of the patients with benign prostatic hyperplasia. But the indications for prostatectomy are still controversial and especially those are more difficult in the cases with small prostate. To determine the efficacy of TURP in the patients with benign prostatic hyperplasia, 138 patients who underwent TURP, were reviewed retrospectively. Group Ⅰ, 66 patients who's volume of prostate were under 30gm, group Ⅱ, 72 patients who's volume of prostate were over 30gm by preoperative ultrasonographic measurement. And then the author made differential analysis for preoperative and postoperative symptom score and maximal urine flow. The following results were obtained; 1) The preoperative symptom score was 10.3 for group Ⅱ, 7.3 for group I, so group Ⅱ showed higher score, in postoperative score group Ⅱ showed 2.5 which was 76% decreased and group I showed 5.6 which was 23.4% decreased, group Ⅱ showed higher decreased rate. 2) Preoperative symptom score of group Ⅱ was higher than that of group I. But postoperative score was no siginificant difference. In decreased ratio, group Ⅱ showed better improvement. 3) Preoperative and postoperative change in maximal urine flow in group I was increased by 44.2%, while in group Ⅱ the flow change showed a 173% increased. In conclusion, without referring to the preoperative measurement of prostatic size. TURP brought improvement of symptoms and maximal urine flow, but when the prostatic size was under 30gm, the improvement degree was minimal and significant increase in maximal urine flow was not shown. According to the results of several objective studies and patient's desire. transurethral rsection could be permitted in patients with BPH of under 30gm. But in the future, studies on the difference in progress the response to management should be done.

The largest character of the modern society, so called the era of the information. is 'c& C'(Computer and communication). As the up-to-date science and new knowledges develope,so far there is increasement of the real necessity of the computer to use huge medical informationmore rapidly and effectively. As the electronic industry is developed, it is possible to do a business with the personalcomputer(PC), which was possible only by a large-computer at past. After the recognition of the rational inevitability of the business computerization, and ifsomeone looks for the sujects to computerize. they must choose the supervision of the clinicaldata about the in-patient first of all. The patient supervising system should retain the databases which serve the reference functionto user's requirements. Under these purposes, it is very important to classify the cases dependingon the names of the diagnoses and operations, and easy and rapid recollect of the appropriatedata. And of course this system also be able to contribute to the research and education aswell as the preservation of the patient data. So. we report the results of 2-year practice in urologic patient supervising program, whichwe enlighted for presenting the guidelines for Program making of the in-patinent data- supervi-sion and the standard for the mandatory clause and database files so that in order to gaugethe ability of the computerization of the patient supervision with PC from now on.

Superfical bladder tumor can be easily treated by transurethral resection, but the recurrent rate is up to 40~70% and if recurred it is more invasive. Lasers can not only destroy tumor tissuebut but also seal up vessels and lymphatics with vaporization and coagulation by virtue of the hyperthermic effect that can occur when intense energy of laser is absorbed and transformed into heat. So it is more effective and safe on treatment of superficial bladder tumor than eletric coagulation. The authors used the Nd-YAG laser for the treatment of 70 patients with superficial bladder tumor and followed more than 12 months at Ewha Womans University hospital from Oct. 1985 to July 1987. The following results were obtained ; 1) Patients' age ranged from 33 to 82 years(mean 57.1) 63 of 70 patients were male and 7 of those were female, Follow up interval ranged from 12 to 52 months(mean 29). 2) Average energy of application was 4,509 joules. Average energy application for single lesion less than 2 cm was 2,977 and that for multiple lesion or more than 2 cm was 16,231 joules, respectively. No spectively. No specific complications were observed. 3) Of 70 patients, 15 patients were recurred and the recurrent rate was 21.4%. The range or currence interval was 3 to 37 months(average 12.1). 4) Of the recurred patients, 73.3% of all cases was recurred within one year. Two cases were progressive to invasive type. 5) Grade was more important factor than stage recurred rate and time. Recurrence rate by grade was 20% in grade Ⅱ and 50% in grade Ⅲ. And recurrence interval by grade were 13.5 month in grade Ⅱ and 4.7 month in grade Ⅲ respectively. We concluded that Neodymium-YAG laser was excellent and safe on treatment of superficial bladder tumor.

Ureteral obstruction is a common and important urologic disorder and may cause a hydronephrosis and result in the deterioration of renal function. We made a clinical analysis on the cause and management of the 69 cases of the ureteral obstruction of the patients in the Department of Urology. Ewha Womans University Hospital during the period from January 1981 to December 1990. The following results were obtained; 1) There were 36 cases(52.2%) of male and 33 cases(47.8%) of female and the major range of age distribution was between 30 decade to 50 decade, 45 cases(65.2%). 2) The level of obstruction was the upper ureter in 37 cases(51.4%), the mid in 2 cases(4.2%) and the lower in 32 cases(44.4%). The affected site was the right in 29 cases(40.3%), the left in 43 cases(59.7%) and the bilateral in 3 cases. 3) In etiology, 59 cases were caused by intrinsic factors, among which chronic inflammation of the ureter was the most common in 36 cases, and the extrinsic causative factors were found in 13 cases. 4) The degree of hydronephrosis was severe in 33 cases(45.8%), moderate in 22 cases(30.6%). mild in 6 cases(8.3%). and non-visualization of kidney in 11 cases (15.3%). 5) As the management of ureteral strictures. nephrectomy was done in 14 cases (19.4%). pyeloplasty in 11 cases(15.3%). ureteroneocystostomy in 5 cases (6.9%), segmental resection and end to end anastomosis in 8 cases(11.1%), ureteral dilation and stenting in 19 cases (26.4%) and percutaneous nephrostomy in 6 cases (8.3%). 6) The improvement of hydroncphrosis was observed in-85.7% on excretory urography, 6 months after treament.

The developments of clean and renewable energy sources are needed in order to reduce dependency of fossil fuel and global warming. Wood pellet is one of clean renewable energy sources and has been considered as one of the substitutes for fossil fuels. Wood combustion is a complex process. It involves many physical and chemical processes. Burning phases of wood pellet can be classified into three modes, 1) gasification mode, 2) flame burning mode and 3) charcoal burning mode. The test equipment used moving grate combustor. Primary air is supplied from the bottom of the grate and the flame is formed above moving grate. case 1) moving grate is organized as horizontal stairs. As increases the number of grate combustion occurs in a lot of unnecessary space. Case 2) the grate was adjusted angle In order to minimize the space below. case1), there was a flame until 8 stairs. The temperature inside the chamber was 1100℃. In case of case2 was a flame until 4 stairs and The temperature inside the chamber was 1200℃. Although the combustion chamber temperature slight increase, the flame length was shorter.

Current Concepts in Bacterial Sexually Transmitted Diseases

Sexually transmitted diseases (STDs) are the most common infectious diseases worldwide, with over 350 million new cases occurring each year, and have far-reaching health, social, and economic consequences. Failure to diagnose and treat STDs at an early stage may result in serious complications and sequelae. STDs are passed from person to person primarily by sexual contact and are classified into varied groups. Some cause mild, acute symptoms and some are life-threatening. They are caused by many different infectious organisms and are treated in different ways. Syphilis and gonorrhea are ancient afflictions. Now, however, Chlamydia is prevalent and has become the most common bacterial STD. Antimicrobial resistance of several sexually transmitted pathogens is increasing, rendering some regimens ineffective, adding to therapeutic problems. A standardized treatment protocol for STDs is recommended to ensure that all patients receive adequate treatment. Appropriate treatment of STDs is an important public health measure.
