제7차 수학과 교육과정에 대한 교사들의 인식과 적용상의 문제점
문선미,박종서 진주교육대학교 과학교육연구소 2000 科學敎育硏究 Vol.26 No.-
This study is designed to find out the understanding of school teachers in relation to the 7th mathematics curriculum revised in accordance with the changes and needs of the day and the problems coming from its application in classes with the help of a questionnaire research, and to come up with the solutions. We worked with first-grade and second-grade teachers in such districts as Chinju, Hadong, Kimhae and Yangsan with the aid of questionnaires, using 285 copies as a means of analysis materials. According to the research, the subjects trunk of the purports or contents of the 7th mathematics curriculum as proper in principle, feeling that it is too ideal a curriculum that doesn't take the given actual condition intro consideration. The subjects hold that the fact that what was originally intended from the 7th mathematics curriculum at the outset fail to be realized in the fields of education is ascribable to such factors as lack of loaming materials, an excessive number of students, too much leaning per period, and lack of their understanding of the curriculum and teaching methods and so forth. We would like to make the following suggestions with a view to working out the problems coming from the application of the 7th mathematics curriculum. First, the number of students per class should be reduced to less than 30. Because it is hard to form mathematic concepts through specific operational activities, playful learning, and intention-exchanging activities due to the present number of students, and it is extremely difficult to carry out level-based classes. Second, standardized learning materials should be provided. Though a large number of learning materials are needed in view of the math text, the actual condition of the schools leaves much to be desired on account of lack of teaming materials, which inhibits classes from going smoothly. Therefore, at least such basic materials as numerical models, cards, and building blocks should be distributed. Third, it is necessary to make policy-related efforts to develop a variety of training programs for the teachers and to expand training opportunities. I would like to suggest that teacher-training programs should be worked out in relation to top-notch thinking or various kinds of theories on math and the reorganization of the curriculum with a view to involve more teachers. With this in mind, such institutions as EBS and Teachers' Training Center, etc. should hopefully work out and implement high-quality teachers' training programs. Fourth, it is necessary for teachers to change their minds. The subjects find it hard to teach their students because there are too many to teach and lean by period and the contents of learning have been upgraded. This is attributable to the teachers' views on the textbook: They regard it as absolute. So it is absolutely necessary for the teachers to apply the curriculum to each class situation based on changes in their minds and to look upon the textbook as one of materials to attain the purpose of education and to be possessed of insight as experts well- versed in the curriculum in a more broad perspective. With this in mind, the teachers should make continuous efforts and at the same time the higher educational institutions also make policy-related efforts to encourage more teachers to make a real study and to make sincere efforts.

Background/Aims It is generally believed that cholecystokinin (CCK) stimulates colonic motility, although there are controversial reports. It has also been suggested that postprandial peptide YY (PYY) release is CCK-dependent. Using a totally isolated, vascularly perfused rat colon, we investigated: (1) the roles of CCK and PYY on colonic motility, (2) to determine if CCK modulates PYY release from the colon to influence the motility and (3) to clarify whether the action of CCK and PYY on colonic motility is mediated via the influence of cholinergic input. Methods An isolated whole rat colon was used. Luminal pressure was monitored via microtip catheter pressure transducers from proximal and distal colon. After a control period, CCK-8 or PYY was administerd intraarterially with or without an anti-PYY serum, loxiglumide or atropine at 12, 60 and 240 pM. Each dose was given for a period of 15-minute and the contractile response was expressed as % changes over basal. PYY concentration in the portal effluent was determined by radioimmunoassay. Results Exogenous CCK-8 increased colonic motility which paralleled the increase in PYY release in the portal effluent. Exogenous PYY also significantly increased colonic motility although it was less potent than CCK. The stimulating effect of CCK-8 was significantly inhibited by an anti-PYY serum, and was completely abolished by loxiglumide, and almost completely abolished by atropine. Conclusions CCK increases colonic motility via CCK1 receptor and it is mediated partly by PYY. Cholinergic input is required for the increased motility by either PYY or CCK.

Common bile duct dilatation after cholecystectomy
Seon Mee Park,Woo Seok Kim,Il-Hun Bae,Ji Hoon Kim,Dong Hee Ryu,Lee-Chan Jang,Jae-Woon Choi 대한외과학회 2012 Annals of Surgical Treatment and Research(ASRT) Vol.83 No.2
Purpose: Bile duct dilatation after cholecystectomy continues to be a matter of controversy. We aimed determine the magnitude of common bile duct (CBD) dilatation after cholecystectomy followed up to 1 year. Methods: Sixty-four cases (age, 47.3 ± 11.7 years; men, 28; women, 36) enrolled in this study. They received laparoscopic cholecystectomy in Chungbuk National University Hospital for symptomatic cholelithiasis or gallbladder polyps with normal bile duct, less than 7 mm. The CBD diameter was measured by one radiologist using ultrasonography at the maximum point after full length evaluation of extrahepatic bile duct. Forty-five and thirty-one cases were followed at 6 months and 1 year, respectively. Results: The CBD was dilated slightly from 4.1 mm at baseline to 5.1 mm at 6 months and 6.1 mm at 12 months after cholecystectomy. The number of cases of CBD dilatation of more than 7 mm at 6 months and at 12 months after cholecystectomy were 11 (24.4%) and 9 (29.0%), respectively. Seven cases at 6 months and 5 cases at 12 months showed bile duct dilation of more than 3 mm compared to baseline. There were no cases having bile duct dilation of more than 10 mm. Conclusion: Postcholecystectomy dilatation of the bile duct occured slightly in most cases. But some cases showed more than 3 mm dilatation over baseline. Asymptomatic bile duct dilatation of up to 10 mm can be considered as normal range in patients after cholecystectomy.

Seon Mee Park 대한소화기내시경학회 2016 Clinical Endoscopy Vol.49 No.4
The management strategy for endoscopic retrograde cholangiopancreatography-related duodenal perforation can be determined based on the site and extent of injury, the patient’s condition, and time to diagnosis. Most cases of perivaterian or bile duct perforation can be managed with a biliary stent or nasobiliary drainage. Duodenal wall perforations had been treated with immediate surgical repair. However, with the development of endoscopic devices and techniques, endoscopic closure has been reported to be a safe and effective treatment that uses through-the-scope clips, ligation band, fibrin glue, endoclips and endoloops, an over-the-scope clipping device, suturing devices, covering luminal stents, and open-pore film drainage. Endoscopic therapy could be instituted in selected patients in whom perforation was identified early or during the procedure. Early diagnosis, proper conservative management, and effective endoscopic closure are required for favorable outcomes of non-surgical management. If endoscopic treatment fails, or in the cases of clinical deterioration, prompt surgical management should be considered.

Genotypic Variation of Helicobacter pylori Isolated from Gastric Antrum and Body in Korean Patients
Park, Seon-Mee,Kwon, Soon-Kil,Son, Bo-Ra,Shin, Kyeong-Seob,Woo, Chan-Won,Kim, Eung-Gook,Kim, Seok-Yong The Korea Society for Microbiology 2000 大韓微生物學會誌 Vol.35 No.1
Although most persons infected with Helicobacter pylori harbor a single strain of the organism, multiple strain colonization in the same patient is also occasionally reported in developed countries. The aims of this study were to determine the prevalence of multiple strain colonization in Korean patients and to detect the cagA, iceA1, and babA status of H. pylori isolated from the antrum and body of the stomach. H. pylori was obtained from 35 patients from the antrum and body of the stomach. The genomic diversity of H. pylori was determined by random amplified polymorphic DNA analysis. The status of cagA, iceA1, and babA genes of H. pylori was assessed by polymerase chain reaction with appropriate primers. Clearly different diversity patterns were identified among the isolates from 35 individual patients. Eighteen (51.4%) patients had a single strain of H. pylori. Eight (22.9%) and nine (25.7%) patients had subtypically (one or two bands difference) and typically (clearly different pattern) different strains of H. pylori in the antrum and body, respectively. Among the 70 isolates of H. pylori from 35 patients, the positive rates of 349-bp and 208-bp cagA gene fragments and the iceA1 gene were 68/70 (97.1%), 68/70 (97.1%), and 58/70 (82.9%), respectively. However, the babA gene was found in 22/66 cases (31.4%). In five out of 18 patients with a single strain, the genetic status of cagA, iceA1, and babA varied between the isolates from the antrum and the body. In 8/17 patients with sub typically or typically different strains, the gene status differed between antrum and body isolates. The prevalence of co-colonization with typically or subtypically different strains is high in Korea, and sub-clones with different pathogenic gene status exist within strains of identical RAPD patterns.
