The purpose of this study is to provide the basic information and efficiency for biology education through analysis and comparison of knowledge part and inquiry part of Life Unit on the seven kinds of the high school 'General Science' textbooks written in accordance with new curriculum. Especially this study is focused on analysis of the inquiry activity of the textbooks. The results obtained are summarized as follows: 1. The numbers of pages about the 'Life' unit are 62 including the appendix among the whole average 476.29 Textbook B and C fill pages the 'Life' unit 63, textbook F 62, textbook D 60. While textbook E contains the 'Life' unit more than any other book as the 80 pages, textbook A and G have the least pages 55. 2. On the basis of the result of analysis to relative rate between the quantity of units and the frequency of research activities, the optimum relative rate is found in the unit 'Nutrition and Health'. 3. Regarding subjects of the similar contents as one subject, the subjects of research activities are 72 kinds and frequency of experiments about them is 127. 'An inherited character of man', 'Controls of sex hormone secretion' and 'Formation of reproductive cells' are common subjects in the 7 different kinds of textbooks. We can know that they are necessary subjects which should be treated in school. 4. The results obtained from analyzing the frequency of research activities and units indicate that, ⓐ The relative rate of the frequency of experiments is 1 in the unit "Nutrition and Health" and the rate is the optimum frequency. ⓑ The relative rate of materials analysis in 1.41 in the unit 'Reproduction' and 0.94 in the unit 'Stimulus and Reaction'. While the former rate is excessively high, the latter rate is the optimum frequency. ⓒ The relative rate of inquiry is 1.11 in the unit 'Heredity' and the rate is also the optimum frequency. ⓓ The relative rate of discussion is 1 in the unit 'Nutrition and Health' and the rate is the optimum frequency. 5. As research activities are emphasized, the development of the subjects and the materials which really can be used in school is need. 6. The quantity of textbook contents have to be decrease for the students can do the research activities. The textbooks should have these materials such as pictures, photographs, something good to read, and puzzles··, etc, that can help students to understand principles, laws and conceptions and also to give students interests and simulations. The textbooks also should be made colorful to improve the visual effects. 7. The textbooks should have many kinds of research activities and various contents in order to give interests and motivation to students. They also have to be considered the conditions of regions, seasons, schools and scientific matters. 8. The study that the class time allotment set on the basis of the quantity of textbook should be performed. 9. General science textbook consists of different units such as 'Physics', 'Chemistry', 'Geoscience' and 'Environment'. As these units are generalized, compared and analyzed on the 7 different kinds of textbook, improving materials should be made for the desirable high school general science education.

Background/Aims DA-9701 is a novel prokinetic agent. In the present study, we investigated the effect of DA-9701 on the motility of the gastric antrum in the normal and clonidine-induced hypomotility in an in vivo animal model. Methods A strain gauge force transducer was sutured on the gastric antrum to measure the contractile activity in rats. A total of 28 rats were subclassified into the 4 groups: (1) the placebo group, (2) the DA-9701 group, (3) the placebo group in the clonidine-pretreated rats, and (4) the DA-9701 group in the clonidine-pretreated rats. After the basal recording, either placebo (3% [w/v] hydroxypropylmethyl cellulose) or DA-9701 was administered. Contractile signals were measured after the administration and after a meal. In the clonidinepretreated rats, either placebo or DA-9701 was administered. Contractile signals were measured after the administration and after a meal. Results Oral administration of DA-9701 did not significantly alter the motility index of the gastric antrum in the preprandial and postprandial periods, compared with the placebo group. The administration of clonidine decreased the motility index of the gastric antrum in the preprandial and postprandial periods, compared with the administration of placebo. This reduction of the antral motility by the administration of clonidine was not observed in the clonidine-pretreated DA-9701 group. The percentage of the motility index in the postprandial period was significantly greater in the clonidine-pretreated DA-9701 group, compared with the clonidine-pretreated placebo group. Conclusions DA-9701 improves the hypomotility of the gastric antrum induced by clonidine, suggesting its gastroprokinetic effect in the pathologic condition.

Je Jung Lee,Jong Hyun Kim,Bung-Nyun Kim 대한소아청소년정신의학회 2021 소아청소년정신의학 Vol.32 No.2

Objectives: The purpose of this study was to evaluate the effects of a school bullying prevention camp for adolescent perpetrators of school violence. Methods: A total of 95 adolescents (boys=73, girls=22) were included in this study. The changes after the program were evaluated using several self-rating scales for the assessment of the degree of depression, loneliness, impulsivity, self-esteem, and interpersonal reactivity compared with the baseline scales. Results: The school bullying prevention camp significantly reduced the degree of depression severity (z=-5.874, p<0.001) and impulsivity scale (z=-3.861, p<0.001), while increasing self-esteem (z=-2.091, p=0.037). The degree of depression severity (z=-4.635, p<0.001), loneliness (z=-2.168, p=0.030), and impulsivity (z=-2.987, p=0.003) significantly reduced, whereas self-esteem significantly increased (z=-2.221, p=0.026) for male students who had no history of child abuse. However, there were no significant changes after the program for the degree of depression, loneliness, impulsivity, self-esteem, and interpersonal reactivity among female students with a history of child abuse. Conclusion: The results of our study suggest that the development of diverse standardized guidance programs is necessary for teenagers with different characteristics and backgrounds. Such programs are expected to be more effective in preventing school violence.

해외교육 치과의사의 국내유입에 따른 치과 의료의 질 보장 및 치과의사의 적정수급

The purpose of this study is to analyze the data on the medical personnel education system and license scheme and provide the basic material for an enhanced qualification system. In China, dental education reform has been underway with a view to providing an inclusive basic medical service package to the whole country by 2020. It is also estimated that the number of Korean dental medicine students in China would be fewer. And most of them desire to get a job in China after acquiring the Chinese license, suggesting little prospect of a massive inflow into Korea in the near future. In Japan, students are required to complete a clinical training program for over 1 year after receiving licenses to become an independent practitioner. But they can apply for the Korean preliminary examination without this post-graduation process. For this reason, the quality issue in license effectiveness review has been seriously discussed. It is deemed desirable to limit the Korean accreditation to Japanese graduates from the dental schools certified by the Japanese dental accreditation body.

The Korean Institute of Dental Education and Evaluation (KIDEE) was established in 2007 to provide the quality assurance in dental education. The KIDEE has been recognized by The Ministry of Education from Jan. 2015 for 5 years. KIDEE had accredited basic dental education programs of all 11 Korean dental schools. The dental accreditation system was introduced to encourage the improvement for dental schools, to ensure the quality of dental practice and most of all, to establish an internationally compatible system of evaluation and accreditation. The accreditation system in Korea is supported by voluntary service of many dental professionals and contribute to improve the quality of dental education program in all institutions. The accreditation by KIDEE let the students and the dentists be taught with assured education program and the all Koreans be cared by the qualified dentists. A quality education system thus provides a sufficient number of qualified dental health professionals to meet the workforce needs of the nation. Ultimately, this should result in quality oral health care for the public. Finally, by specifying the competencies of graduates, the standards will define the scope of dental practice. This may serve to define the profession of dentistry and differentiate it from other health professions, or to differentiate among the specialties in dentistry in the case of advanced dental education programs.

Large Liver Cell Dysplasia in Hepatitis B Virus X Transgenic Mouse Liver and Human Chronic Hepatitis B Virus-Infected Liver

Koo, Ja Seung,Seong, Je Kyung,Park, Chanil,Yu, Dae-Yul,Oh, Bong-Kyeong,Oh, Seung Hyun,Park, Young Nyun S. Karger AG 2005 Intervirology Vol.48 No.1

<P><I>Objectives:</I> Large liver cell dysplasia (LCD) is frequently associated with hepatitis B virus (HBV), but it remains uncertain whether it is reactive, senescent or preneoplastic. <I>Methods:</I> The HBX transgenic mice and normal control mice were sacrificed at 1, 3, 5, 7, 9, 11, 13 and 15 months after birth. Twenty-three cases of human B viral chronic hepatitis/cirrhosis with prominent LCD were selected. The immunohistochemical stain of proliferating cell nuclear antigen (PCNA), transferase-mediated dUTP-biotin nick end labeling (TUNEL) assay and senescence-associated β-galactosidase (SA-β-Gal) were evaluated. <I>Results:</I> In HBX transgenic mice, LCD was developed since 3 months and formed small nodules of hepatocellular adenoma, which progressed to hepatocellular carcinoma. The hepatocytes with LCD in HBX transgenic mice showed significantly higher PCNA-labeling index (LI) and lower TUNEL-LI than normal hepatocytes of control mice (p < 0.05). In the majority of human B viral chronic hepatitis/cirrhosis, the hepatocytes with LCD revealed higher PCNA-LI and lower TUNEL-LI than those without, when compared in each case using the same tissue block. SA-β-Gal staining showed no difference between hepatocytes with and without LCD. <I>Conclusion:</I> It is suggested that LCD, related to HBV, might not be just an innocent bystander, but closely related to hepatocarcinogenesis.</P><P>Copyright © 2005 S.
