A 4-month-old intact male Sapsaree dog was referred due to a history of postprandial regurgitation following consumption of solid food. Thoracic radiography revealed focal leftward displacement of the thoracic trachea at T1 to T4 vertebrae levels. Barium contrast radiography revealed focal dilation of the cranial thoracic esophagus at the heart base level. Persistent right aortic arch (PRAA) with an aberrant left subclavian artery branching from the patent ductus arteriosus was diagnosed by computed tomography angiography (CTA). Although barium contrast radiography can presumptive diagnose PRAA, CTA should be considered for identifying additional vascular anomalies, specific types, and surgical planning.

An 11-year-old, castrated male dog presented with a 3-month history of cough and depression. Auscultation revealed systolic murmur and thoracic radiographs showing enlargement of both the atrium and left ventricle. Echocardiography showed thickened mitral valve and moderate-to-severe left atrial enlargement. Additionally, M-mode echocardiography showed symmetric left ventricular wall thickening and systolic anterior motion of the mitral valve, while Doppler imaging revealed high velocity turbulent flow through the left ventricular outflow tract. Based on echocardiography, this case was diagnosed with hypertrophic obstructive cardiomyopathy. After 5 months, the dog was clinically static in radiography and echocardiography.

We present a rare case of massive intracerebral hemorrhage resulting from a small, superficially-located supratentorial cavernous malformation, or cavernoma. These lesions rarely lead to massive, life-threatening intracerebral hemorrhages. A 17-year-old female presented with a 3-week history of declining mental status. Brain computed tomography and magnetic resonance imaging revealed a sizable intracranial hemorrhage, within the right occipital region, associated with a small nodule at the hematoma's posterior margin. An emergency operation removed the entire hematoma and nodule. Histological examination of the nodule was compatible with a diagnosis of cavernous malformation. The patient's post-operative course was uneventful.

A 6-year-old male domestic shorthair cat was referred to Gyeongsang National University Animal Medical Center for labored breathing. According to the patient's history, the client had fed him commercial dog foods. The patient's hematological, radiographic, and echocardiographic examinations were evaluated for diagnosis. Echocardiography results showed marked dilations of ventricles and atriums and mitral regurgitation. A systolic dysfunction was detected. Plasma taurine concentration was lower than the reference range. Based on these results, the patient was diagnosed with feline dilated cardiomyopathy associated with taurine deficiency. Treatment included feline commercial foods, taurine, digoxin, furosemide, and clopidogrel. Digoxin was changed to pimobendan when normal blood pressure was achieved. Clinical signs improved gradually and no abnormalities were detected on echocardiograms at 10 weeks following onset of treatment.

In arctic zone of West Siberia, native people's bodies were sometimes mummified inside the medieval graves. In 2013 to 2017, we conducted the excavations of medieval graves at Zeleny Yar cemetery in Yamalo-Nenets Autonomous Okrug. Among the burials, current report deals with the mummy grave #79. During the investigation, bronze plate and strips, woven or fur clothing, leather strap, beads, bronze bracelets, and iron knife etc. were collected. Anatomical and radiological research showed that the mummy was found intact with hair, skin, and skeletons, but the preservation status of soft tissue differed greatly depending on the area. The brain and eyes were well preserved, but the chest and abdominal organs almost disappeared. The arms were preserved to some extent, but only the bones remained in the legs. The West Siberian mummy could be a great resource for anthropologists to reveal the biological aspects of arctic indigenous people.

Background: Assessment of the radiation doses to which workers are exposed can differ depending on the placement of dosimeters on the body. In addition, it is affected by whether the placement is under or over a shielding apron. This study aimed to evaluate the actual positioning of personal dosimeters on the body, with or without shielding aprons, among radiation workers in Korea. Materials and Methods: We analyzed the survey data, which included demographic characteristics, such as sex, age, occupation, work history, and placement of the personal dosimeter being worn, from a cohort study of Korean radiation workers. We assessed the use of personal dosimeters among workers, stratified by sex, age, working period, starting year of work, and occupation. Results and Discussion: Overall, high compliance (89.1% to 99.0%) with the wearing of dosimeters on the chest was observed regardless of workers' characteristics, such as age, sex, occupation, and work history. However, the placement of dosimeters, either under or over the shielding aprons, was inconsistent. Overall, 40.1% of workers wore dosimeters under their aprons, while the others wore dosimeters over their aprons. This inconsistency indicates that radiation doses are possibly measured differently under the same exposure conditions solely owing to variations in the placement of worn dosimeters. Conclusion: Although a lack of uniformity in dosimeter placement when wearing a shielding apron may not cause serious harm in radiation dose management for workers, the development of detailed guidelines for dosimeter placement may improve the accuracy of dose assessment.

최근 세계적으로 유라시아 대륙의 경제적 중요성이 부각되면서 동서를 연결하던 고대 교통로에 대한 연구의 필요성이 증대하고 있다. 국내 학계에서 유라시아 동서 문명 교섭에 대한 연구는 아직은 그다지 활발할 편이 아니지만 역사학, 고고학, 미술사, 민속학, 복식사 등 다양한 분야에서 꾸준히 연구를 진행시켜 왔다. 북방 초원길을 통한 교섭사는 한민족과 한국문화의 기원에 대한 관심에서 비롯되었는데, 몽골과 카자흐스탄지역의 유적에 대한 직접적인 조사가 꾸준히 이루어지면서 흉노, 쿠르간 문화 등으로 연구영역이 확장되고 있다. 사막과 오아시스의 길을 통한 교섭은 미술사 분야에서 연구를 주도해왔다. 이란, 우즈베키스탄, 아제르바이잔 등에 대한 현지조사가 다양한 경로를 통해 진행되면서 신라의 황금문화, 유리의 전래, 불교문화의 동전 등 다양한 주제에 대한 연구가 심화되고 있다. 바닷길에 대한 연구는 다른 분야에 비해 부진한 편이다. 동남아시아에 소재하는 불교와 힌두교 사원에 대한 관심은 적지 않았으나 이 유적들을 연결하는 바닷길의 복원과 그 의미에 대한 연구로 확산되어야 한다. 베트남의 돈 손 문화와 싸 후인 문화 유적을 국내 연구자들이 직접 조사하게 됨으로써 앞으로 이 분야 연구가 활성화될 것으로 기대된다. 앞으로는 한국사, 한국 문화와 직접 관련이 없는 주제에 대해서도 관심을 가져야 한다. 인류 공동의 문명을 연구하고 보존하는 것도 우리의 책임이기 때문이다.

Our previous research on coprolite specimens from the mummies of Joseon Dynasty (1392-1910 CE) has revealed various species of parasite eggs. Herein, we added 2 new helminthic cases of human remains from Joseon-period graves in the Republic of Korea (Korea). The organic materials precipitated on the hip bones of 2 half-mummied cases (Goryeong and Gwangmyeong cases) were collected, rehydrated, and examined by a microscope. In the sample from Goryeong-gun (gun=County), ova of Trichuris trichiura, Clonorchis sinensis, and Metagonimus spp. were detected, and eggs of T. trichiura and A. lumbricoides were found from the sample of Gwangmyeong-si (si=City). By adding this outcome to the existing data pool, we confirm our previous estimates of Joseon-period parasite infection rates. The overall rates of A. lumbricoides, T. trichiura, and C. sinensis decreased dramatically from Joseon to the modern period. In Goryeong mummy specimen, we also found Metagonimus spp. eggs that has rarely been detected in archaeological samples so far.

Purpose: Health management programs should provide comprehensive health services for students and staffs at schools. Health management programs are critical for helping students become adults with physically, mentally, and socially good health conditions. The aim of this study was to identify the past and present history of health management programs and health laws to help schools develop future health plans. Methods: This study was conducted by analyzing reference data collected using data from Ministry of Education and Science Technology, Korean Educational Development Institute, Korea Centers for Disease Control and Prevention, and National Statistical Office as well as legal documents from the Legislative Office related to school health from 2001 to 2010. Results: Health management programs in schools included three sections: disease prevention and control, physical examinations, and prevention of communicable diseases. Disease prevention and controls consisted of obesity control, drug abuse prevention and control,and management of students' mental health. Various strategies and services were developed to improve health status of students for 10 years from 2001 to 2010. School health laws and systems have been established for disease prevention, physical examinations and communicable disease control as well, to improve students' health as well. Conclusion: The history of health management programs has a number of implications to help design future plans for school health programs and services for students and staffs.
