This study was focused on improvement of milk production in Mongolia dairy industry by artificial insemination (AI) technology, of which was supported from ODA project of KOICA in Republic of Korea. The study was started from January 2009 to present and 3rd years in this year. So, all data, especially synchronization and pregnancy of dairy cows (Holstein) will be summarized in final result in this year. For synchronization, total 81 dairy cows selected from 4 private farms that were 38, 30, 8 and 5 in Undarmal milk, Onjin (Enkhbayer), Jargalant, and BRM School, respectively. All the dairy cows were injected intramuscular (IM) of 5 ml PGF2α in the vulva and detected estrus 2 to 3 days after PGF2α injection. Total 78 out of 81 dairy cows (96.3%) were detected estrus by only 1 time injection of PGF2α. The dairy cows that were induced estrus, inseminated with 0.5 ml dairy frozen semen by conventional AI techniques. The pregnancy diagnosis of the AI dairy cows was detected by uterus palpation after 60 days of insemination. Total 75 from 78 inseminated dairy cows (90.1%) were diagnosis pregnant. The estrus induction and pregnant rate were very effective using PGF2α injection and conventional AI techniques in Mongolia dairy cow. The results indicated that AI after estrus induction in Mongolia dairy cows could be applied to dairy breeding technology to improve the breeding efficiency and milk production.

연골육종은 비교적 서서히 자라며 늦게 전이하는 악성 연골 종양으로 알려져 있다. 골 연골종에서 발생한 속발성 연골육종은 발생빈도는 드물며 타부위로의 전이가 적고 악성도가 낮은 경우가 많아 적합한 수술적 치료로서 좋은 예후를 보이는 것으로 보고되고 있다. 본 동국대학교 정형외과학 교실에서는 우측 대퇴골 원위부 골간단부에 생긴 고립성 골 연골종에서 이차적으로 발생한 연골육종을 치험한 바 문헌고찰과 함께 보고하는 바이다. A case of Secondary Chondrosarcoma Arising from Solitary Osteochondroma of the Distal Femur Department of Orthopaedic Surgery, College of Medicine, DongGuk University Phil Hyun Chung M.D., Jung Su Hwang M.D., Suk Kang M.D., Yang Mln Kim M.D., Hyung Ho Oh M.D., Dong Ju Chae M.D., Jong Pil Kim M.D. Chondrpsarcoma is a malignant cartilage-forming tumor that grows slowly and metastasis of this tumor occurs in late stage. Secondary chondrosarcomas arising from a solitary osteocartilaginous exostosis are rare and those have a better prognosis than other chondrosarcomas, and they rarely metastasize. We present our experience with a case of secondary chondrpsarcoma arising in solitary osteochondroma of distal metaphysis of right femur with clinical details.

Objective : The purpose of this study was to assess the effect of acupuncture treatment for chronic headache patients using power spectrum analysis of the heart rate variability(HRV). Methods : 15 clinical experiment participants were gathered and through a questionnaire patients who experienced headache for more than 4 hours a day and more than 15 days per month were qualified as Chronic Headache patients. Treatment was applied 2 times a weeks for 8 weeks. The acupoints, GV20, HN23, ST8, HN46, TE17, GB20, LI20, LI11, LI14, ST36, and LR3 were stimulated for 20 minutes. The effects of acupuncture treatment were analyzed using power spectrum analysis of the HRV, HRV was recorded before and after acupuncture treatment. Results : HRV before and after treatment was compared after 8 weeks of acupuncture treatment. Increase in mean values of SDNN and RMSSD were observed but the increases were not statistically significants. Increase in mean values of TP, LF and HF were observed but, the increase was significant(p<0.05) only in TP. Conclusions : The results suggest that acupuncture treatment on chronic headache patients can increase the activity of autonomic nervous system. Further use of HRV for quantitative analysis of acupuncture treatment on autonomic nervous system related symptoms is suggested.

본 연구는 저소득층 중학생을 대상으로 비만도에 따른 스트레스, 자아존중감, 학교생활적응의 차이를 조사하였다. 조사 대상자는 지역주민센터 자료를 근거로 저소득층 확정을 받은 기초생활수급자, 차상위 계층 가정의 학생들을 대상으로 2015년 7월 3일부터 2015년 7월 17일까지 2주간에 걸쳐서 조사하였으며, 조사대상 인원은 총 440명이었다. 비만도 평가는 대한 비만학회의 규정에 따라 BMI<18.5은 저체중, 18.5≤BMI≤22.9은 정상, 23.0≤BMI≤24.9은 과체중, BMI≥25.0은 비만으로 분류하였다. 스트레스 조사는 가정환경, 친구, 학업, 교사/학교 등 4가지 하위 영역별로 구분하여, 총 27문항으로 구성된 도구를 활용하였으며, 청소년의 자아존중감에 대해 10문항으로 구성하였으며, 자아존중감 조사지의 신뢰도 값은 Cronbach α=.967이었다. 청소년의 학교생활적응은 5개 영역으로 구성되어 있고, 5개 영역은 교사관계적응, 교우관계적응, 학교수업적응, 학교생활적응, 학교환경적응 등 이며, 각 영역은 4문항으로 총 20문항으로 구성하였다. 본 연구의 결과, 비만군에서 스트레스 정도가 높게 나타났고, 정상체중군은 스트레스 정도가 가장 낮게 나타났으며, 비만군에서 학교생활 적응이 가장 낮게 나타났으며, 정상체중군은 학교생활 적응이 가장 높게 나타났다. 비만군에서 자아존중감이 가장 낮고, 정상체중군은 자아존중감이 가장 높게 나타났다. 비만도는 스트레스와 양의 상관관계를 나타내었으며(p<0.01), 비만도와 학교생활적응은 음의 상관관계를 나타내었으며(p<0.001), 스트레스는 자아존중감과 음의 상관관계를 나타낸다(p<0.01). 스트레스와 학교생활적응은 음의 상관관계를 나타내었고(p<0.01), 학교생활적응은 자아존중감과 양의 상관관계를 나타내었다(p<0.01). 본 연구의 결과를 종합해보면, 저소득층 학생은 비만군의 분포가 가장 높고, 비만군일수록 스트레스 정도가 높으며, 학교생활 적응이 낮고, 자아존중감이 낮게 나타났다. This study aims to investigate the differences in stress, school life adaptation and nutrient intakes according to obesity of middle school students from low income class. The subjects of the survey were selected among students from low income class, confirmed as national basic livelihood security recipients, and classified as lower income group, based on community service center data. As for measurement tools, BMI was calculated, which was used for the measurement of their obesity. For stress, the four-point Likert scale on daily stress was used, which was developed for Korean adolescents by Han (2011). For school life adaptation, the five-point Likert scale by Choi (2010) was used as a measurement tool. For self-esteem, the four-point Likert scale by Lee (2013) was used as a measurement tool. The results of this study were as follows: Most of the students from the low income class belonged to the obese group. Among the middle school students from the low income class of the Daegu area, the obese group had lower scores in all five domains of school life adaptation (teacher relationship, peer relationship, school class, school life, school environment), while the normal weight group had higher school life adaptation. Among the middle school students from the low income class of the Daegu area, the obese group had lower self-esteem, while the normal weight group had higher self-esteem.

Obesity is growing problem in Korea. We had a case of bariatric surgery during gastric cancer operation. Patient was 29 year old Korean lady with early gastric cancer located in the lesser curvature side of the middle 1/3 of the stomach. Her body weight was 89 kg, height 163 cm, and thus body mass index was 33.5 kg/m2. Preoperative blood pressure was 130/90 mmHg, hemoglobin 12.9 g/dL, total lymphocyte count 3,280/mL, serum albumin 4.3 g/dL, CEA 1.1 ng/mL, CA 19-9 9.1 ng/mL, and alpha fetoprotein 2 ng/mL. Another associated disease was right thyroid follicular neoplasm. The chest X-ray was normal. After IM injection of 2,500 units of heparin 30 minutes before the induction of general anesthesia, she received curative subtotal gastrectomy and Roux en Y gastrojejunostomy when a malabsorption loop of 120 cm jejunum was incorporated between the Treitz ligament and the end to side jejuno-jejunostmy site at May 29th 2006. Her postoperative course was uneventful except a minor wound seroma and the elevations of serum amylase(up to 4 folds) and lipase(up to 2 folds). She lost her body weight 9 kg in 5th, 21 kg in 7th, and 27 kg in 10th postoperative months to became 61.5 kg. On follow up exams in July 2008, she gained 4 kg to overcome her weakness and fatigue. From the above result, the incorporation of a malabsorption loop during reconstruction phase of gastric cancer operation was a good option for obese gastric cancer patients especially in cases of early gastric cancer.

정용기,박수정,이현규 대한금속재료학회 2003 대한금속·재료학회지 Vol.41 No.10

Nickel aluminides are a family of materials which offer the potential of improved high temperature performance over conventional nickel based superalloys. The synthesized material has been characterized by x-ray diffraction, scanning electron microscopy, energy dispersive spectroscopy and selected area image analysis. The mechanical properties of the Ni₃Al/NiAl alloy have been determined as a function of temperature through compressive and four point flexural tests. The lamellar aluminide provides synergistic properties of each of the monolithic aluminides resulting in appreciable room temperature tensile ductility, reasonable room and elevated temperature fracture toughness and higher compressive yield strength than those of obtained in monolithic NiAl.

정민수,신현성 한국학교수학회 2001 韓國學校數學會論文集 Vol.4 No.2

The selected questions for this study was their conversation in problem solving way of working together. To achieve its purpose researcher I chose more detail questions for this study as follows. ① What is the difference of strategy according to its level? ② What is the mathematical ability difference in problem solving process concerning its level? This is the result of the study ① Difference in the strategy of each class of students. High class-high class students found rules with trial and error strategy, simplified them and restated them in uncertain framed problems, and write a formula with recalling their theorem and definition and solved them . High class-middle class students' knowledge and understanding of the problem, yet middle class students tended to rely on high class students' problem solving ability, using trial and error strategy. However, middle class-middle class students had difficulties in finding rules to solve the problem and relied upon guessing the answers through illogical way instead of using the strategy of writing a formula. ② Mathematical ability difference in problem solving process of each class. There was not much difference between high class-high class and high class-middle class, but with middle class-middle class was very distinctive. High class-high class students were quick in understanding and they chose the right strategy to solve the problem. High class-middle class students tried to solve the problem based upon the high class students' ideas and were better than middle class-middle class students in calculating ability to solve the problem. High class-high class students took the process of reflection to make the answer, but high class-middle class students relied on high class students' guessing to reconsider other ways of problem-solving. Middle class-middle class students made variables, without knowing how to use them, and solved the problem illogically. Also the accuracy was relatively low and they had difficulties in understanding the definition.

Objective : Because the cause and etiology of chronic headache are not yet fully explained, the treatment of this symptom is not simple. In order to study the effectiveness East-West pain treatment on chronic headache, we evaluated its effect of pain alleviation and quality of life improvement on chronic headache patients who were treated with nerve block and acupuncture, and only acupuncture for eight weeks. Methods : 92 clinical experiment participants were gathered and through a questionnaire patients who experienced headache for more than 4 hours a day and more than 15 days per month were qualified as chronic headache patients. The qualified patients were classified into two groups, nerve block and acupuncture group(EW group, n=49) and acupuncture group(E group, n=43). Treatment was applied 2 times a weeks for 8 weeks. The acupoints, GV20, HN23, ST8, HN46, TE17, GB20, LI20, LI11, LI14, ST36, and LR3 were stimulated for 20 minutes. The effects of two groups were analyzed using VAS scores and BPI(Brief Pain Inventory). Results : The VAS and BPI after four weeks of treatment showed significant improvement among two but differences between the three groups was statistically insignificant. The VAS and BPI of the EW group after eight weeks of treatment showed statistically significant improvement compared to the other two groups. Conclusion : The pain treatment for chronic headache might be contributed to improvement of quality of life as well as alleviation of pain of chronic headache patients. It was suggested that the West pain treatment in combination with East pain treatment might be an useful modality to improve the pain and quality of life in chronic headache patients.

The incidence of hematologic disorders in patients with Down's syndrome is significantly increased, about 14∼30 - fold higher than in general population and includes neonatal transient abnormal myelopoieis and acute leukemias. The age of onset of leukemia in Down's syndrome is peaking first in the newborn period and then under 4 years of age. Down's syndrome with acute leukemia above the age of 20 is very rare and it's treatment oucome is unclear. The treatment of Down's syndrome with leukemia has been controversial because of toxicity and associated congenital cardiac and other abnormalities. But if treated adequately, children with Down's syndrome show a favorable response to anti-leukemia therapy. A 24-year-old man with Down's syndrome was first seen for the evaluation of anemia and thrombocytopenia. The peripheral blood morphology and bone marrow study revealed acute myelogenous leukemia, cytogenetic study of bone marrow showed trisomy 21. Beacuse of his sicioeconomic condition and medical abnormalities including deafness, visual loss, he was treated with low dose subcutaneous cytosine arabinoside(Ara-C) for 11 days. Complete remission was obtained after 37 days. The complete remission lasted for 5 months. He subsequently relapsed, and died 6 months later.
