We performed thoracoscopic resection for diagnosis in 41 year-old-female presenting with multiple pulmonary nodules in both lung fields, which was detected incidentally on routine chest x-ray and followed by additional exmaminations including chest CT scan and percutaneous needle aspiration biopsy under the presumptive diagnosis of metastatic cancer. During thoracoscopy, the result of the frozen section analysis of multiple masses revealed strong evidence of leiomyoma. In her past medical history, she had undergone myomectomy, and hysterectomy, 7 year ago and 10 year ago, respectively. Based on permanent, special staining of specimen, estrogen receptor assay and review of past specimen of uterine myoma the final diagnosis was benign metastasizing leiomyomata from uterine myoma, the report was very uncommon in Korean and English literatures. The patient has been followed up for 2 year without special therapy, such as hormonal therapy.

A number of research papers have reported more frequent occurrence of rheumatic/autoimmune disease among patients with hypogonadism or a chromosomal anomaly with potential X-chromosome defects. A 30-year-old female patient came to the hospital with a main cause of bilateral buttock pain, which began two years ago and worsened seven days ago. Ankylosing spondylitis with invasion of both sacral-iliac joints was observed. On magnetic resonance imaging, although the uterus was observed normally, an ovary was not observed. In a chromosome test, balanced reciprocal X-1 translocation of 46,X,t(X;1)(p10;q10) was diagnosed. Here, we report on the first case involving ankylosing spondylitis accompanied by balanced reciprocal X-1 translocation.

A four-year old bitch which showed occasional hemomorragic exudate from the vulva for two weeks after the previous estrus 7 months ago was ovariohysterectomied. About 200m1 of sanguineous fluid was flowed out from the uterus and some scattered blood clots were found in both uterine horns. Hematometra of the bitch which was presumed to occur during the proestrus two weeks ago was thought to progress into early pyometra at the time of diagnosis. To diagnose hematometra, vaginal examination using vaginal speculum or vaginoscope and hematological examination were performed. Radiography and ultrasonography were also proved to be of use to diagnose hematometra. Treatment for hematometra was considered to be the same as for the case of pyometra.

A species of moss (Musci) is observed on the Matanuska Glacier of Alaska in the middle of summer. The life cycle of the moss is perfectly observed. This is very rare and special because the environment is completely glacial and barren of plants. Matanuska is a gigantic glacier formed about 18,000 years ago in the Palmer region near Anchorage. It has a dimension of 27 miles in length and 4 miles in width. The glacier is located in the region between Anchorage and Mount McKinley. This huge glacier carved the Matanuska valley thousands of years ago. The mighty glacier also forms the Matanuska River. The summer weather is very changeable throughout the day: warm, cold, sunshiny, windy, cloudy, rainy, snowy, foggy, etc. The Arctic clouds move very quickly and create variable climates. So there are four seasons even in one day during the summer period of this region.

Medical student examination questions of 60 years ago are very rare to find irrespective of medical specialty. Recently, medical student examination questions for thoracic and cardiovascular surgery were found, which were presented between 1957 and 1959 at Seoul National University Medical College. All examination questions were hand-written in six pages by a professor as examiner. Among the six pages, four examination papers were dated and/or the target grade was identified, while the remaining two did not offer any information. These materials are thought to have a valuable historical meaning for the Korean medical community as well as the Department of Thoracic and Cardiovascular Surgery at Seoul National University Hospital.

The Seosan Group in the Taean peninsular can be divided into Seosan formation and Daesan formation according to its metamorphism and stratigraphy. The Seosan formation is composed of iron bearing quartzite and schist which are strongly metamorphosed and migmatized about 2572 m.y.ago. The Daesan formation is composed mainly of quartzite and crystalline limestone. They were intruded by granite gneiss 2370m.y ago and metamorphosed two or three times before Jurassic Period. The Group is overlain by Taean formation which shows low grade metamorphism. Total three times metamorphic events can be recognized in these areas. First and second metamorphisms are predominent in amphibolite facies, the last metamolphism is mostly greenschist facies.

Extraction of old pacemaker leads remains a complex procedure owing to fibrotic encapsulation and lead adhesions. We report a case of extraction of 15-year-old pacemaker leads by weight and pulley method. A 81-year-old man presented with exposed pacemaker leads out of body with purulent discharge from a pacemaker insertion site. He inserted DDD (dual chamber pacing, dual chamber sensing dual function) pacemaker implantation 15 years ago for SSS. Previously pacemaker battery was removed 3 years ago due to recurrent infection of pacemaker scar site. We extracted the pacemaker leads by weight and pulley method successfully without any complications.

$C^*$-algebras which are closed sub-algebras of Banach algebras have been studied many years ago. In this note we extend the main definition of $C^*$-algebras to metrizable topological algebras.

Background and Objectives : Peritonsillar abscess is one of the most common illnesses m the ENT field, though its prevalence has been drastically reduced with the development of antibiotics and appropriate early treatment. We analyzed recent clinical characteristics of peritonsillar abscess and compared them with ones of 7 and 14 years ago respectively. Materials and Methods : Sixty-six cases of peritonsillar abscess from 2006 through 2008 were investigated retrospectively and compared with results of 7 and 14 years ago on various clinical factors. Results : Peritonsillar abscess was prevalent in men in their 20s and 30s. Mean period from symptom onset to visit to hospital tended to decrease(5.2 days) but admission days has increased(7.4 days). Body temperature on admission was lower than that of previous studies($36.4^{\circ}C$). Bacteria were isolated in 26 cases(74.2%) out of 35 cases in which culture had been performed. The most common cultured organism was a-hemolytic streptococcus and $\beta$-hemolytic streptococcus that had been most frequently cultured 14 years ago wasn't detected in this study. Conclusion : We found some changes of clinical features in peritonsillar abscess when compared with previous researches. Although there were some differences in cultured organism, antibiotics used commonly-cephalosporin, aminoglycoside, quinolone - were still effective for their eradication.

체선ㆍ 체화시간의 경제적 가치추정은 항만의 투자나 운영효율화를 위한 의사결정에 필요한 가장 기초적이고 풍요한 자료이다. 이에 대한 연구는 ‘70∼80’년대에 걸쳐 Goss와 Mann의 연구와 세계은행을 중심으로 선박과 화물이 가지고 있는 장기기회비용관점 (long-term opportunity cost)에서 추정된 바 있으며 국내에서도 10년 전에 이와 동일한 방법으로 추정된 바 있다. 이 논문의 목적은 10년 전 연구를 최근의 자료를 이용하여 재조사하는 것이다. 국적선 외항선사의 약 47.5%에 해당하는 선박 205척으로부터 입수한 선박관련 소요경비, 무역통계, 해양수산통계 통을 이용하여 체선ㆍ체화비용을 추정하였다. 추정결과 저자의 10년 전 연구와 비교하여 액체화물선과 산물선의 체선비용이 증가하였으며 특히 액체화물선의 비용은 두 배 가까이 증가하였다. 이는 고가의 LNG선이 투입됨으로써 선박의 시간당 기회비용을 증가시킨 때문이다. 10년 전과 비교하여 체선ㆍ체화의 시간비용이 크게 상승하지 않은 것은 사회적 할인율이 하락한 때문인 것으로 밝혀졌다. 사회적 할인율의 차이에 따른 감도분석이 실시되었다.
