In this study, prestressed hybrid wide flange (PHWF) composite girders were proposed, and full-scale flexural tests were conducted to evaluate their structural performances. This new proposed girder system was developed and designed to effectively resist external loads considering the actual construction sequences. Two specimens with and without shear connectors were fabricated and tested to examine the effect of the shear connectors for achieving the fully-composite behaviors between a cast-in-place (CIP) concrete and the prefabricated prestressed steel–concrete composite girder. The test results showed that sufficient flexural strengths and deformation capacities can be obtained in both types of PHWF composite girders with and without shear connectors. To reflect the actual construction stages of the proposed PHWF composite girder, nonlinear flexural analyses were proposed considering the prestress effect and segmental effect before and after composite with the CIP concrete, respectively. The observed and analysis results of strain behaviors of the PHWF girder specimens were also compared and discussed in detail.

In recent years, gonorrhea has been pandemic and remains one of the most common STDs in the world, especially in developing countries. For the detection of a more effective therapeutic regimen and assessing the prevalence of Penicillinase Producing Neisseria gonorrhoeae(PPNG), we have been trying to study the patients who have visited the Venereal Disease Clinic of Choong-Ku Public Health Center in Seoul since 1980 by menas of the chromogenic cephalosporin method. In 1998, 93 strians of N. genorrhoeae were isolated, among which 60(64.5%) were PPNG. The prevalence of PPNG in Seoul, which had been decreased to 39% in 1996 after a peak of 74.3% in 1993, is increased to 64.5% in 1998.

A large number of dancers of foreign countries today undertake the choreography on the theme of the Bible based on their artistic inspirations and actively create dance plays in the form of art in missionary works and church services. According to this trend, results of research works show the characteristics of the Bible in itself with a lot of subject matters and dramatic elements. The Bible has provided so many stories and worked as resources of infinite inspiration in the dance as well as other fields of art like this. Many works based on the Bible nowadays were created in a field of church services and missionary dances, or in a pure field of artistic embodiments. The Bible extended a creative range of the dance, having a religious effect on general audience in a form of art, and, at the same time, and furnishing basic data for activating the creativity of the dance for church services or missionary works. At this point of time that a range of Christian arts is being extended in various fields of society, particularly, it is necessary that missionary and dancing groups dynamically show activity in works for establishing the Christian dancing in our culture for showing the grace and love of God through the medium of the dance using human body.

Effects of acetic acid, malic acid and citric acid on copper dissolution from new and used copper saucepans at different concentrations (0, 0.02, 0.04, 0,1, 0.2, 0.4, 1,0, 2,0, 4.0%), different boiling times (0, 10, 20, 30, 40, 50, 60mins.), and different temperatures (5, 20, 40, 60, 80, 100%)were investigated. As acetic acid concentration increases, copper content increases. Copper dissolution concentration from copper saucepans at boiling in malic acid increases more than in acetic acid or citric acid, At above 60℃, as the temperature increases, the concentration of copper dissolved from copper saucepans also increases. As boiling time increases, the concentration of copper dissolved from copper saucepans also increases. In addition, through repeated use, the concentration of copper increases as well. And copper concentration dissolves in large amounts from used saucepans rather than new saucepans. The dissolution of copper with distilled water by repeated use does not dissolve at all. 1% acetic acid dissolves in large quantities.

Background: Pulmonary paragonimiasis is caused by consumption of raw or improperlycooked crustacea infected with the laval stage (metacercaria) of Paragonimus westermani. The most characteristic symptoms were rust-colored sputum and cough. Paragonimiasis causes pleural thickening or effusion in 48% of the patients. Pleuro-pulmonary paragonimiasis can be easily overlooked by physicians who do not suspect this disease in the differential diagnosis. Method: We compared the outcomes of 11 patients with paragonimus empyema managed either through thoracotomy or pig-tail catheter drain. These patients were confirmed by food history, clinical and radiological findings, and laboratory data. Results: The male and female ratio was 1.75 : 1, and mean age was 40.0 ± 13.5 years. AII patients had pulmonary symptoms such as cough or chest pain. Serum-ELISA for paragonimiasis were all positive (mean titer was 0.57). AII patients had pleural effusion in radiological findings( 2 patients had bilateral pleural effusion). All patients received praziquantel (75 ㎎/㎏/day for 3days). Two patients were treated with thoracotomy and nine patients were treated with pig-tail drain. Hospital stay were 14.5 days in thoracotomy group and 5.6 days in pig-tail group respectively, Conclusion: Compared to the conventional thoracotomy grouP, the patients with paragonimus empyema who received pig-tail catheters had a significantly-decreased period of drain in situ, were clinically improved earlier, and were discharged earlier.

선제형,박진석,한민석,김수항,김우진,박인형,이숭,유종선,박찬국 朝鮮大學校 附設 醫學硏究所 2006 The Medical Journal of Chosun University Vol.31 No.3

Gastritis cystica profunda (GCP) is a rare disease characterized by gastric foveolae elongation along with hyperplasia and cystic dilatation of the gastric glands extending into the tissue beneath the submucosa. GCP mainly develops at the gastroenterostomy stoma but can arise in a stomach that has not undergone surgery. The proposed pathogenesis is related to chronic inflammation, ischemia and the presence of a foreign body. GCP may present as a submucosal tumor, Polyp or a giant gastric mucosal fold. Endoscopic ultrasonography (EUS) is an effective diagnostic method for differentiating GCP from protruding and elevated gastric lesions. We report a case of GCP along with the endoscopic and EUS findings that were indistinguishable from a malignant submucosal tumor.

Background: Hospital employees are exposed to various hazards, and turn out neglecting to health problems caused by these hazardous factors, so it is necessary to measuring hospital working environment. Methods: This study was performed to evaluate the possible effects on health following exposure to low levels of ethylene oxide in central supply sterilizing room workers. Questionnaires, measuring the volume of ethylene oxide exposure, hematologic and urinary examination were performed and the obtained results were as follows : Results: 1. Four(l7.4%) workers answered as "very serious" and 9(39.1%) answered as "serious" to the survey about the understanding the effect on the individual health when they use ethylene oxide, 9(39.1%) replied as "Yes" and 14(60.0%) replied as "No" about the question if they get the regular education, 19(82.6%) agreed to the necessity of measureing the working environment. It was found that 6(26.1%) wear the protector and 17(73.9%) do not wear the protector during their work. 2. The exposure concentration of ethylene oxide in the central supply sterilizing room was measured as follow : Average 0.076 ppm for the individual exposure, average 0.106 ppm for the main operating room, and average 0.088 ppm for the side operating room. 3. As the result of the hematologic examination, the average rate of each part except for the number of leucocytes was included in the normal category. There was a significant statistical difference in the number of leucocytes between the exposed group and the control group(p<(0.05). 4. The exposed group was divided 2 groups according to their working period as over 12 year group and under 12 year group. Although the average rate of each part was analyzed as normal, the number of leucocytes showed a significant statistical difference between the two groups(p<0.05). 5. There was no significant statistical difference between the exposed group and the control group in the urine protein test. Conclusions: Tlt is considered that they need the measuring equipment and the constant measuring management of the working environment. Furthermore, regular safety education for the preventive plans for the health troubles and keeping the rule of earing the protector during their work are recommended.
