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.

Review : The Crucial Role of Cholangiocytes in Cholangiopathies

( Seon Mee Park ) The Editorial Office of Gut and Liver 2012 Gut and Liver Vol.6 No.3

Cholangiopathies are diseases involving the intrahepatic bili-ary tree. They appear to involve, chronic inflammation of the bile ducts, which can lead to the development of bile duct cholestasis, proliferation/ductopenia, biliary fibrosis, and malignant transformation. Sustained stimulatory insults to biliary epithelial cells can induce a ductular reaction, which has a key role in the initiation and progression of cholangi-opathies. The epithelial-mesenchymal interaction between reactive cholangiocytes and mesenchymal cells with the in-flammatory infiltrates plays a major role in this pathogenesis. Cytokines, chemokines, growth factors and morphogens me-diate these interactions in an autocrine or paracrine manner. The main hepatic myofibroblasts (MFs) in cholangiopathies originate from portal fibroblasts. Hepatic stellate cells and fibrocytes also transform into MFs. Whether cholangiocytes or hepatocytes are a source of MFs via the epithelial-mes-enchymal transition (EMT) remains a matter of controversy. Although there have been numerous indirect findings sup-porting the theory of a cholangiocyte EMT in human tissues, recent studies using lineage tracing methods have demon-strated strong evidence against the EMT. Understanding the pathogenic mechanisms involved in cholangiopathies can allow for better-targeted anti-fibrotic therapies in animal models. Before anti-fibrotic therapies can translate into clini-cal trials, improved monitoring of the fibrotic progression of cholangiopathies and an accurate assessment regarding the effectiveness of the proposed treatments must be achieved.

Mechanism of Action of Cholecystokinin on Colonic Motility in Isolated, Vascularly Perfused Rat Colon

( Seon Mee Park ),( Joung Ho Han ),( Hee Bok Chae ),( Sei Jin Youn ),( Byeong Seong Ko ),( Jee In Jeong ),( Kae Yol Lee ) 대한소화기기능성질환·운동학회(구 대한소화관운동학회) 2011 Journal of Neurogastroenterology and Motility (JNM Vol.17 No.1

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.

N/A Objectives : Clinical presentation of Helicobacter pylori (H. pylori) infection has marked variation mainly due to the strain diversity and host susceptibility. Although H. pylori is identified as a major risk factor for gastric and duodenal ulcers, the ulcerogenic or pathogenic strain has not been documented yet. The objective of this study was to investigate antigenic types of the ulcerogenic strain of H. pylori. Methods : The sera of atients were tested by Western blot using Helicoblot 2.0 for six major anti-H. pylori antibodies, together with CLO test and histological examination of gastric biopsy tissues. Thirty-five, nine and 20 patients had duodenal ulcer, gastric ulcer and chronic active gastritis, respectively. The antigenic types of H. pylori were analyzed in 54 patients with positive H. pylori infection. In this study, H. pylori was divided into four serotypes according to the presence and absence of CagA and VagA : type I; CagA(+) and VacA(+), type Ia; CagA(+) and VacA(-), type Ib; CagA(-) and VacA(+), and type II; CagA(-) and VacA(-). Results : There was no difference in the number of bands for six antigens : 3.2 ± 1.4, 3.0±1.2 and 3.1±1.4 in 35 duodenal ulcer, 7 gastric ulcer and 12 chronic gastritis, respectively. The band with 119 kDa was 90.7%, which was the most common band with the order of 35, 30, 26.5, 89 and 19.5 kDa. Type I, Ia and Ib were positive in 22.2, 42.6 and 27.8%, respectively, which were significantly higher than type II (p <0.05). There was no difference in the positive rates of four urease subtypes between the four serotypes. Conclusions : H. pylori had the marked diversity in antigenic patterns. The strain producing CagA and/or VagA was suggested to be a pathogenic strain.

<P><B>Abstract</B></P><P><I>Objective</I>: Caregivers may experience positive or negative feelings about their role. The study investigated the determinants of the burden and positivity of family caregivers of Korean terminal cancer patients.</P><P><I>Methods</I>: A multicenter cross‐sectional survey was conducted with 139 family caregivers. Determinants of caregiver's burden and positivity were assessed by the Caregiver Reaction Assessment Scale and by three questions based on a previous study, respectively. Two separate hierarchical multiple regression models were used.</P><P><I>Results</I>: Each domain of the caregiver's burden and positivity was explained by different factors, with the total explained variance ranging between 14.4–33.6% and 2.6–18.3%, respectively. Caregivers who were unmarried, less educated, and/or had low incomes were more likely to be negatively affected, while those who shared caregiving responsibilities were less prone to negative consequences. Caregivers who were male, religious practitioners, and who perceived a higher burden of schedule disruptions were more likely to have a positive perception of their role, while those who perceived a lack of family support were less likely.</P><P><I>Conclusions</I>: Our results highlight the importance of sharing the caregiving burden with the other family members. Organizing a family meeting can provide an opportunity for other family members to acknowledge the feelings and reactions of the primary caregivers, and can prompt the sharing of caregiving responsibilities.

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.
