In this work, we aim to develop and fabricate a water-saving mechanical system that can be installed to various types of facets in a modular way and operates in a fully mechanical manner without any power supply so as to ultimately save the energy usage. This product is divided into a driving gear part involved in valve opening and closing and a escapement part that secures water usage time. This system is expected to be installed in public places at no high cost and time to save water usage and also to improve users’ awareness for saving water. 본 개발은 모듈식으로 설치할 수 있고 별도의 전원 없이 완전 기계식으로 작동하는 절수 시스템을 제작하여 에너지 절약을 실천할 수 있도록 하는 것을 목표로 한다. 본 제품은 크게 밸브 개폐에 관여하는 구동 기어부와 물 사용 시간을 확보하는 탈진기 부로 나뉘고 공공장소에 큰 비용 및 시간 필요 없이 설치되어 사용자의 인식 개선 및 물 절약을 실천할 수 있을 것으로 기대된다.

Infection with human papillomavirus(HPV) is considered to be the principal causal agent in the development of the uterine cervical cancer. To detect HPV types prevalent in carcinoma of the uterine cervix, a type-specific, sensitive polymerase chain reaction(PCR)-based assay for HPV types 16, 18, and 33 was applied to 40 cervical carcinomas(39 squamous cell carcinomas and 1 adenocarcinoma), 6 cases of cervical intraepithelial neoplasia(CIN), and 18 samples of cervicitis and histologically normal cervix. PCR was done using 2 sets of Ll primer of HPV-16 and 18, 1 set of E2/E1 primer of HPV-33, and 3 sets of E6 primer of HPV-16, 18, 33. The amplified product was analyzed directly on the basis of the size of the ethidium bromide-stained band visible after agarose gel electrophoresis, which was confirmed by Southern blot hybridization. The results were as follows : 1. As expected, the combined incidence of the common high-risk genital HPVs(types 16, 18 and 33) was high in carcinomas (82.5%) and CIN 111(66.7%), low in CIN 1(33.3%), and nonexistent in the normal controls. 2. By using L1 primers and E1/E2 primers in 46 CINs and cervical carcinomas, HPV DNA was detected in 36(78.3%), which were 65.2%(30/46) for HPV 16, 8.7%(4/46) for HPV 33, 6.5%(3/46) for HPV-18, and only 1 case of mixed infection of HPV-16 and HPV-18 was detected. All normal cervices and cervicitis tissues were negative for HPV 16, 18 and 33. By using E6 primers, 35 (76.1%) cases were positive for HPV DNA, which were 67.4%(31/46) for HPV-16, 4.3%(2/46) each for HPV-18 and HPV-33. HPV 16 is the most common type present in squamous cell carcinoma. 3. There was no difference in detection rates of HPV DNA according to patients age in cervical carcinoma (p=0.188). 4. There were good correlation between the results obtained by PCR using Ll or E1/2 primer and those by E6 primer. The concordance rates were 93.8%(60/64) for HPV-16, 98.4% for HPV-18, and 96.9% for HPV-33. 5. There was no difference in detection rates of HPV DNA according to clinical stage in cervical carcinoma(p=0.2). 6. The detection rate of HPV DNA in case of serum SCC level under lOng/ml was 100%(17/17), which was higher than those in cases of serum SCC levels of 10ng/ml or more. "The detection rate was significantly decreased as serum SCC became high in level(p=0.012). 7. There was no difference in detection rates of HPV DNA according to tumor size in cervical carcinoma (p=0.743). 8. The reccurrence rate of patients with HPV-16 containing tumors was 28.6%((8/28), which was 3.4 times more than that of patients without HPV-16, but it was not statistically significant(p=0.162). The survival rate of patients with HPV-16 containing tumors was 82.1%, which was not different from from that of patients without HPV-16 containing tumrs(p=0.405). In conclusion, papillomavirus, especially HPV-16, played some role in the development of cervical cancer. There was no association between the HPV infection and the clinical characteristics including prognosis. However, in contrast to other studies, HPV type 18 and 33 were not the common type of HPV. Perhaps more cases should be analyzed.

This study is a clinico-statistical analysis of 19 cases of ectopic pregnancy which developed after laparoscopic tubal sterilization during the period from January 1983 to December 1985 in Chungnam National University Hospital. The results were as follows : 1. Among the 140 cases of ectopic pregnancy during the period, 19 cases(13.6%) were disclosed to occur after laparoscopic tubal sterilization. 2. The most frequent age group was in 26 to 30 years and the mean age was 31.2 years. 3. The average gravidity and number of living children were 4.1 and 2.6, respectively. 4. All patients were easily diagnosed preoperatively by culdocentesis, pregnancy test, diagnostic laparoscopy and sonography. 5. About 74% of the total patients presented themselves within 3 years after tubal sterilization, with shortest interval being 4 months, the longest 12 years, and mean 2 year 5 months. 6. The methods of sterilization was mostly electrocauterization (73.9%) and the rest was silastic band application (26.3%). 7. The average duration from last menstrual period of patients to the diagnosis of ectopic pregnancy was 6.2 weeks. 8. The majority of the patients presented with lower abdominal pain, nausea & vomiting, and bearing down sensation. 9. The most implantation site of ectopic pregnancy was fallopian tube(94.8%). 63.2% of the ectopic gestation was located in the distal of fimbrial segment and 31.6% in the proximal segment. 10. The average amount of intraperitoneal blood loss was 1190ml. 11. 89.6% of total cases was treated by unilateral salpingectomy or unilateral salpingooophorectomy.

Objectives: This study was undertaken to determine if Plantaginis Semen(PS) has a protective effect against $CCI_4$ induced hepatoxicity in Rats. Methods: The experimental groups were divided into Normal group (untreated Group), Control group $(group\;treated\;with\;CCI_4)$, Sample 1 (group treated with 0.1 ml Plantaginis Semen herbal acupuncture in both sides of $G\bar{a}nsh\bar{u}\;(BL_{18})$ after $CCI_4$ treating) and Sample 2 (group treated with feeding of 1 cc Plantaginis Semen extraction after $CCI_4$ treating). Rats were administered orally $CCI_4\;(0.1\;ml/kg)$ for 4 days. In experiments for PS effect, rats of Sample 1 group received 0.lml herbal acupuncture of PS extraction in both sides of corresponding $G\bar{a}nsh\bar{u}\;(BL_{18})$ of human body for 3 days after treated $CCI_4$. Rats of Sample 2 group feeded PS extraction (1cc) for 3 days after treated $CCI_4$. Variation of weight and biochemical assays (AST, ALT, LDH, ALP, total cholesterol, triglyceride, total protein, albumin) were performed. Results: In Control group, $CCI_4$ increased serum AST, ALT, LDH, ALP, total protein, albumin and decreased weight, total cholesterol, triglyceride. Sample 1 and Sample 2 significantly decreased serum AST, ALT, LDH, ALP, total protein, albumin as compared with Control group. Conclusion: These results indicate that PS could be used in prevention and treatment of hepatoxicity. However, precise mechanisms of PS protection remain to be determined.

Methods: The experimental groups were divided into Normal group (untreated Group), Control group (group treated with CCl4), Sample 1 (group treated with 0.1 ml Plantaginis Semen herbal acupuncture in both sides of Ganshu (BL18) after CCl4 treating) and Sample 2 (group treated with feeding of 1 ㏄Plantaginis Semen extraction after CCl4 treating). Rats were administered orally CCl4 (0.1 ㎖/㎏) for 4 days. In experiments for PS effect, rats of Sample 1 group received 0.1ml herbal acupuncture of PS extraction in both sides of corresponding Ganshu (BL18) of human body for 3 days after treated CCl4. Rats of Sample 2 group feeded PS extraction (1㏄) for 3 days after treated CCl4. Variation of weight and biochemical assays (AST, ALT, LDH, ALP, total cholesterol, triglyceride, total protein, albumin) were performed. Results: In Control group, CCl4 increased serum AST, ALT, LDH, ALP, total protein, albumin and decreased weight, total cholesterol, triglyceride. Sample 1 and Sample 2 significantly decreased serum AST, ALT, LDH, ALP, total protein, albumin as compared with Control group. Conclusion: These results indicate that PS could be used in prevention and treatment of hepatoxicity. However, precise mechanisms of PS protection remain to be determined.
