The purpose of this study was to determine the incidence and therapeutic outcomes of canine oral tumors in Korea. Medical records of dogs presented with oral tumor at the Veterinary Medical Teaching Hospital of Seoul National University from 2002 to 2007 were reviewed. The predominant breeds were Yorkshire terrier (n=14), miniature poodle (n=7), Shih Tzu (n=6), and maltese (n=4), in order. The mean age at onset was $10.0{\pm}3.8$ years. The most common tumor types included fibrous epulis (n=13), malignant melanoma (n=12), acanthomatous epulis (n=4), and squamous cell carcinoma (n=3). Surgical removal was performed in 29 cases; simple excision in 18 cases, partial mandibulectomy in 8 cases, and partial maxillectomy in 3 dogs. Outcomes of surgery were various according to the tumor types. Prognosis of dogs with fibrous epulis and acanthomatous epulis was good and that of dogs with malignant melanoma was poor.

It has been criticized that there are discrepancy between 'general statements' of the curriculum and subject-matter curricula. The possible reasons for this are as follows: The developers of the general statements were educational curriculum specialists. These specialists were not good enough to develop general statements and guidelines of subject matter curricula reflecting the characteristics of science contents, to examine developed science curriculum, and to give feedback to science curriculum developers. Under the present curriculum developing system where curriculum is developed in ten months or less by the research team commissioned unpredictably and imminently, it might be difficult to develop valid and precise science curriculum reflecting the purport of the general statements and teachers' needs. The inadequacy of these curriculum development processes resulted in (1) inconsistent statement about the school year to be applied to differentiated curriculum, (2) abstract and ambiguous stating about the characteristics, teaching-learning and assessment guidelines of enrichment activities, and (3) failure to reduce science contents to a reasonable level. Therefore curriculum development centers should be designated in advance to do basic research at ordinary times, and organized into a cooperative system among them. Two years or more of developing time and wider participation of scientists are recommended to develop more valid and precise science curriculum. In addition, commentaries on science curriculum should be published before textbook writing begins.

This study examined the qualities of an effective teacher needed to accomplish educational reform successfully and prepare for a rapidly changing knowledge-based society. To achieve the purpose of the study, the following specific questions were looked into; (1) knowledge, skills, attitude of an effective teacher. (2) a proposal for staff development programs to improve the effectiveness of teachers. (3) a proposal to support teachers' efforts to improve their effectiveness. (4) the factors inhibiting the improvement of teachers' effectiveness. In this study, 'in-depth interview' was used for data collection because the study deals with the "subjective consciousness" of teachers, and qualitative research methods are useful to such a case. The research was done on teachers from secondary schools in Pusan City. According to the teachers interviewed, an effective teacher needed in the new age has such knowledge, skills, and attitude as; (1) knowledge in their major, general culture and common sense, psychology of educational counselling, social science, and knowledge and information related to curriculum. (2) effective instruction skills, skills to guide student behavior, skills related to administrative clerical work, using the computers, extra curriculum activities, educational evaluation, using teaching materials, developing educational programs, and good communication skills. (3) attitude relevant to willingness to understand and converse with students at their cognitive level, positive expectations and concern toward students, democratic problem solving, continuous self-study and development, thoroughgoing mission and professionalism, will for educational reform and innovation, neat appearance and refined language, and successful interpersonal relationships. The teachers also said that the current staff development system, as a program to provide necessary qualities for teachers, has improved in the last 3 years through diverse curriculum and systematic programs. However, due to the problematic promotion system, the staff development program has turned into just a 'point collecting' game from the role of in-service training program; teachers take training courses as the means just collecting points for promotion purpose. Factors inhibiting the improvement of teachers are (1) overload of formal paperwork over emphasizing outcome, (2) mannerism of teachers not perceiving their lack of professionalism, (3) the general attitude in the teaching profession resisting change and reform, (4) supervisory activities lacking rigid regulation, (5) research just as the means of point-collection only for promotion, and (6) staff development programs lacking efficiency. These factors, interacting each other, inhibited the improvement of teachers.

An evaluation system of teaching is one of authentic assessment tools for improving the quality of higher education. The purpose of this study is to cultivate the class evaluation system in the college of engineering based on the empirical analysis of the results of the class evaluation. Especially, this study investigates the validity evidence using the confirmatory factor analysis of the class evaluation. The data used in this study were acquired from 49,127 student's evaluation responses of 471 courses offered in colleges of natural science and engineering at a university in Korea. The reliabilities are quite good for every construct by producing an index value from 0.92 to 0.98. The results provides a guideline for an appropriate measurement model to report the information, to clarify quality and appropriateness of instrument items, to make recommendations for which items should be left or merged in the revised instrument. A special suggestion for improving student's evaluation of each course is to prepare a well-designed instruction for students explaining why and how to evaluate the course in order to produce reliable and valid results.

Huh-joon's medical thoughts shown on his medical book of the Doog-Eui-Bo-Kham can be summerized as follows. 1. The general trend of medical science in Koryo dynasty is that much more interests were concentrated upon the books about curative means rather than upon the books about theoretical knowledge of medical science. With the development of Hyang Yak(鄕樂) (the term referring either various kinds of domestic medical stuffs such as herbs or the curative methods using those stuffs) and the writing of books on Hyang Yak, independent medical science of the nation's own was established in late Koryo dynasty. And the national medical science was continuously further developed until early Choson dynasty. Briskly-expanded mutual exchanges with China in early Choson dynasty provided Choson opportunities to import Chinese medical science and to examine it. Under this circumstances, he wrote the Dong-Eui-Bo-Kham. 2. As we look over the preface and Chip-Rae-Muo(集例文), we can find the characterstic of Doog-Eui-Bo-Kham is that the philosophical theory of Taoism was quoted in explaining the principles of his medical science and that the main idea of Naekyuog is the basis in explaining the way of curing diseases. 3. 83 kinds of medical books were quoted in the Doog-Eui-Bo-Kham. Besides, as many as 200 kinds of books including Tao-tzu's teaching books(道書), history books(史書), almanac(曆書), and Confucius' teaching books(儒家書籍) were quoted in total. Naekyuog and Eue-Hak-Ip-Mun, Dan-Kye-Sim-Bup were the most frequently quoted books among them. 4. Huh-Joon's medical thoughts about health care were like these. 1) The reason why Huh-Joon regarded the idea of health care as of great importance was that he laid much more emphasises on the preventive medicines rather than on the remedial medicines. The direct reason was that he was greatly influenced by profound knowledge of Taoist's study of discipline and who participated in the editing the books from the beginning. 2) Huh-Joon's outlook on human body started from the theory of "Unity of Heaven and Man"(天人合一論), which implied man was a kind of miniature universe. In addition to that, he largely theory of essence(精), vital force(氣), and spirit(神) which were regarded very important as the three most valuable properties in Taoism. However, he took his medical ground on practical and pragmatic idea that he did not discuss fundamental essence(元精), fundamental vital force(元氣), and fundamental spirit(元神) which were given by Heaven from the received only the theory of essence, vital force, and spirit which were acquired after birth and worked mainly on realistic activity of life. 3) Huh-loon accepted Do-In-Bup(導引法) sharply as a method to prevent and cure diseases. 5. Huh-loon's medical thoughts on remedial aspects are as 1) Naekyung was considered so important in Dong-Eui-Bo-Kham that not only each paragraph was begun with the Quotations from Nackyung but also the edited order of the content of the book the same with that of Naekyung. And differently from the former korean medical books he accepted at large and recorded the theories of the four noted physicians of the Geum-Won era(金元四大家) by Dong-Eui-Bo-Kham. 2) For the first time, Huh-Joon introduced the theory of Un-Ki (運氣論) in the Dong-Eui-Bo-Kahm. However, he accepted it as a pathological function of human body but he did not apply physical constitution, physiological function, pathological function, and remedial methods. 3) Huh-loon liked to use Hyang Yak that he recorded korean name of Hyang Yak(鄕名), places of the production(産地), the time of collecting(採取時月), and the way of drying herbs(陰陽乾正法) in the remedial method of a single medicine prescription for diseases at the end of each paragraph. By doing so, he developed, arranged, and revived Hyang Yak. 4) He believed that since the natural features of China were different from those of Korea the reasons of being attacked with its remedial methods couldn't be the same with different from Chinese medical books which primarily focused on paralysis and the injury of the cold has his own structure in his book that he founded independent science of this nation. He consulted enormous documents He discovered and wrote the theory and therefore concrete methods for diseases so that the book hadthe principles of outbreak of diseases(理), methods of cure(法), prescription(方), and a single medicine prescription(藥) and set system of medical science in a good order. By doing so, he and pragmatic development of medical science.

It is well known that human brain has the advantage of handling disperse and parallel distributed data efficiently. On the basic of this fact, artificial neural networks theory was developed and has been applied to various fields of science successfully. In this study, error back propagation algorithm which is one of the teaching technique of artificial neural networks is applied to predict ultimate bearing capacity of pile foundations. For the verification of applicability of this system, a total of 28 data of model pile test results are used. The 9, 14 and 21 test data respectively out of the total 28 data are used for training the networks, and the others are used for the comparison between the predicted and the measured. The results show that the developed system can provide a good matching with model pile test results by training with data more than 14. These limited results show the possibility of utilizing the neural networks for pile capacity prediction problems.

As the competition among college graduates in the job market keeps getting intense, the educators' role of preparing students to get well adapted to the job environments should be more emphasized. However, in reality, many firms admit that many entry-level employees out of college need to be reeducated in a variety of areas. To resolve this problem, the current paper aims to propose some suggestions for a better school curriculum that reflects the needs and demands of the industry. The present proposal is based on my empirical knowledge from the department of computer science of the college where I am teaching and can be applied to other colleges. The suggestions for restructuring of a curriculum are expected to help students actively deal with the trend of developing technology. This restructured curriculum should help colleges produce workers with a good balance of academy and industry who can be assigned to work without being reeducated in the field.

The purpose of this study was to examine professors' and students' perceptions of curriculum that fosters character in medical school. 'Character' can be defined as a desirable personality and the ability to be a good person. A total of 264 subjects (professors=131, students=133) participated in the study. Survey questions were divided into the three parts (education needs, factors of character, and curriculum management strategy). Data were analyzed by using t-test and one-way analysis of variance. Both professors and students recognized the need for character education. Professors were more aware of the need for education than students (t=4.35, p<0.01), and clinical professors were more aware of the need for education than basic medical science professors (t=3.48, p<0.01). Premedical students were more aware of the need for character-centered education than medical students in the later stages of their education (t=3.41, p<0.01). Professors and students commonly referred to 'consideration and communication' as the most important factor in building character. Professors considered 'self-regulation' more important than the students recognized, while students perceived 'wisdom' as more important than the professors did. There was a difference in preference for curriculum development (creating new subjects vs. revising existing subjects) between the two groups. However, both groups agreed on the teaching and evaluation methods. In conclusion, both groups acknowledged the need for character education. However, there were differences in perception on the major factors of character and preference for curriculum development. The results of this study may assist in designing character education in medical education.

An 8-year-old, male Shih-tzu dog with clinical signs of hemorrhage from penile orifice and pain on lifting hindlimb was brought to the Veterinary Medicine Teaching Hospital, Chungnam National University. The patient was shown polyuria/polydipsia (PU/PD), more than 10 times per day, and gasterointestinal signs such as intermittent vomiting and melena. On laboratory examination, BUN, creatinine and amylase level were all highly increased. Radiographic and ultrasonographic findings included that both kidneys were abnormal, and both prostates were hyperplastic bilaterally and cysts were presented in parenchyma. Additionally, hyperechoic pancreas and intact urinary bladder were observed from ultrasonographic examination. The dog was diagnosed as pancreatitis, acute renal failure and benign prostatic hyperplasia (BPH). After the appropriate treatment for pancreatitis and acute renal failure, He dog was treated with administration of azasteroid for BPH. On day 71 after azasteroid treatment, good response to the treatment was defined by ultrasonography and clinical signs cured completely.

Background and purpose : Drug abuse is one of the most serious problems among the Korean adolescents today and has been associated with delinquent behavior in adolescents. The number of adolescents who abuse drugs is increasing yearly. Solutions to the problem, however, have not been well developed. The purpose of this study was to determine the effectiveness of a drug use prevention program which was developed by researchers. The program was a modified DARE(Drug Abuse Resistance Education) program for Korean adolescents. Methods: This study used an experimental, one-group pretest-posttest design with a convenience sample of 122 middle school students who were at one middle school located in Seoul. Data were collected using a self-administered questionnaire where ‘knowledge and attitude about drug use’, ‘social skill’, and ‘self-esteem’ were measured. The program had 12 sessions to improve knowledge and attitudes towards drugs, decision making skills, social resistance skills, management of stress and self-esteem of students. Teaching strategies for each session were varied lectures, group discussion. role-playing, question-and-answer sessions and audiovisual materials. Paired t-test was used to analyze the differences between the pre- and post-test scores on knowledge of and attitudes towards drug use, social skills, and self-esteem. Results : There were significant differences in knowledge and attitudes about drug use between pretest and post-test (p＜.05), but no significant differences in social skill and self-esteem(p＞.05). Conclusion: Our results showed that the drug use prevention program was not effective in promoting social-skill and self-esteem of Korean adolescents. These findings might be due to the respondents being in the period of early adolescence (puberty) and not being good at group discussion. So, further study is needed to develop a drug use prevention program appropriate to students 9 and 10 years old, and to encourge small group discussion.
