홍기언,김의한,김민관,양승하,강상균 순천향의학연구소 1995 Journal of Soonchunhyang Medical Science Vol.1 No.1
The uterine cervicitis by chlamydia trachomatis(CT) shows no specific clinical symptoms except mucopurulent leukorrhea, but it causes severe complications such as endometritis, salpingitis, abortion and infertility. Fortunately, the treatment of cervicitis by CT is simple and effective, so that this infection is once diagnosed and then confirmed, the treatment is not difficult. To study the positive rate of CT infection, we collected 65 patients inflicted with mucopurulent leukorrhea in Chonan city. Specimen was collected by swab and for the detection of CT, ELISA was carried out. The positive cases are observed in 15 out of 65 patients (positive rate is 23.1%). This positive rate was rather lower than other reports, however, this results were higher we expected With this result, the clinicians keep in mind the fact that the causes of uterine cervicitis by CT occupy the large proportions as gonorrhea.

A novel 1.31/1.55μm silica based wavelength filter using multi-mode interference (MMI) coupler was developed. To design a compact device size, the wavelength filter is optimized to received signal which is from a fiber and has 1.55μm-wavelength. Because 1.31μm-wavelength transmitted signal can be amplified before transmission, it can be valuable to have output intensity of more than 60% for transmitted signal. The wavelength filter is designed using MMI coupler to achieve a compact, tolerant, and polarization independent optical device. The filter is fabricated by commercially available technology for Ge-doped SiO_(2) waveguide on Si substrate. For small dimensional optical device, 1.2% index difference between core and clad is used. Consequently, excess loss is 0.18dB, extinction ratio is 18.7dB, and PDL is 0.26dB at 1.55m, excess loss is 5.22dB, extinction ratio is 3.18dB, and PDL is 0.32dB at 1.31m for the wavelength filter.

The currenty offered experiment courses are completely reconsidered and reconfigured. The whole subjects are divided into 10 seperate courses, each of which should represent either basic or advanced stages of differing fields of the electronic engineering. It has been aimed that the courses form an elaborate hierachy so that they are minimally redundant but linked to one another in their fringes. Also, it has been pursued that the new courses should not fall obsolete in at last next five years exploring the maximum possibilities of the currently available equipments.

In sculpture and building construction, stone has been generally used as basic material. However, the Information of its characteristics are poor to use stone in these fields. So this study focused on various characteristics of domestic and overseas natural stone. This study provides the basic data for the choice of stone to be used in sculpture and building construction and will be a foundation of further study of new method in manufacture and construction.

The purpose of this study was to investigate the effect of regular physical activity on the physique, body fat and physical fitness. The test sample was selected which were attending "kid fitness scout" at SAKA. 1.Physique score Males score were higher than female score in body height, body weight, chest girth and abdomen girth according to aging. and also there are significant difference between male and females, seven age groups in body height, six age groups in body weight, six and seven age group in chest girth. 2.Body fat by physical measurement Body surface area, body volume, body density, body fat, fat free weight were growth and development constantly but percent fat was decreased. However, there are significant difference between males and females, six age group in body surface area (P<0.05), body volume(P<0.001), percent body fat(P<0.001), body fat(P<0.001), fat free weight(P<0.001) were significant difference between the groups. 3.Physical fitness Sit and reach test, foot and toe balance, standing long jump, v-form sit and shuttle run score were growth and development by aging. Particularly, Female's score was higher than mate's score in sit and reach test but males's score was higher than females in standing long jump, v-form sit. and also female's five, six age group were higher score than males foot and toe balance, shuttle run score, but males's score was more higher than females in seven ages group, There are significant difference between male and female. Six age group(P <0.01), seven age group (P<0.001) In slut and reach test, five age group(P<0.05) In foot and toe balance, five·six·seven ages group(P<0.001) In standing long jump, and six ·seven ages group(P<0.01) in shuttle run.

A 40-years-old woman was admitted to this hospital with flank pain and high grade fever for 2 weeks. As a matter of her past history, extracorporeal shock wave lithotripsy (ESWL) was performed for treatment of renal stones 5 years ago. Her abdominal CT findings were hydronephrosis with pyonephrosis and renal stones. Antibiotics administered for 5 days had no effects on her symptom improvement. A right ureteral stricture was noticed by ultrasonography follow up. We inserted double J stent and continued antibiotics therapy for 10 days, and then her fever was disappeared and flank pain was improved. ESWL is one of the most important treatment of renal and ureteral stone. However, its complications should not be negligible including bleeding, pain, ureteral obstruction, infection and so on. Complications of ESWL can be divided into acute and chronic courses. When we treat pyelonephritis patient with past history of ESWL, possibility of ureteral stricture must also be considered. In this study we report a case of pyelonephritis caused by ureteral stricture, possibly as a chronic complication of ESWL performed 5 years earlier

The structures are generally deteriorated with time, and then the strengths of them shall be lowered. Considering decrepitude, the strengths of a steel reinforced concrete (S.R.C.) and reinforced concrete (R.C.) columns are affected by variations in the strengths of concrete and steel, the cross-sectional dimensions of concrete and steel section, the placement of steel section and reinforcing bars and the strength model itself: Their factors are stochastic variables; elapsed time after construction, crack and neutralization or carbonation of concrete, corrosion of reinforcing bars, etc. On each case of S.R.C & R.C. columns, these several variables, the strengths which have been acquired by using Time Dependent Reliability analysis method, will be analyzed and compared with the strength by reinforced concrete criteria and LRFD(Load & Resistance Factor Design) criteria. The stochastic strengths of members suggested in this study will be useful for the life-cycle management.

However, Endoscopic retrograde cholangiopancreatography (ERCP) is still helpful procedure for the diagonosis of the pancreatobiliary disease and treatment through endoscopic sphinterectomy (EST) is relatively safe, these have possiblity of complications such as hemorrhage, infection, panceatitis, and perforation. ERCP related perforation was rarely reported in 0.3 to 1.1% of previous study, but most serious complication. A report of Pneumomediastinum, Tension Pneumothorax complicating perforation after ERCP and EST is very uncommon. In our hospital, we experienced case of pneumomediastinum, subcutaneous emphysema, and tension pneumothorax after ERCP and EST, and the patient (a 58 years old female with suspicious common bile duct stone) was treated successfully with conservative treatment.

The expression of pro-apoptotic molecules, p53 and Bax, in the spinal cord of rats with experimental autoimmune encephalomyelitis (EAE) was examined. Apoptosis was confirmed by the terminal deoxynucleotidyl transferasemediated dUTP nick end-labeling (TUNEL) method. TUSEL (+) apoptotic cells were mainly either ED1 (+) macrophages or T-cells in the parenchyma of E N . Western blot analysis showed that both p53 and Bax expression significantly ( p < 0.01) increased in the spinal cords of EAE rats at the peak stage, and thereafter declined. An immunohistochemical study showed that inflammatory cells (notably T cells) in the parenchyma express p53 and Bax, while brain cells, includng neurons and glia, were devoid of these nuclear staining of these molecules. The nuclear expression of p53 largely matches apoptotic cells in the parenchyma of EAE. These finchngs suggest that pro-apoptotic molecules, p53 and Bax, may play an important role in eliminating T cells in the parenchyma in EAE.
