The woodcut of flowers and birds is a field that has not been almost covered in studies of old prints. This seems related to the lack of modernistic studies on the paintings of flowers and birds (hwajohwa). During the Chosun Period, this painting genre was popular among high officials and commoners as well as in painters' circles. While having received influence from China and its neighboring countries, it is used to create unique painting styles with the change of the times. This suggests that the painting genre has played an important role in the Korean painting history-and so should not be easily ignored. Since there was much influence from Japan during the Japanese colonial period, however, those flowers-and-birds paintings were recognized to belong to a Japanese painting genre even after the restoration of Korea's independence in 1945. That would be why little attention is being paid to the painting genre today. As a result, such recognition has led to the lack of studies regarding the flowers-and-birds paintings, and in turn it has influenced a lack of understanding concerning the importance of those woodcuts, in addition to the reality that there are few remaining woodcuts of flowers and birds. Accordingly, this study is focused on the flowers-and-birds woodcut that has not been almost dealt with in the previous studies on old prints. Its purposes are to promote the understanding about the woodcut confirm its position as an old printing area and provide a new basis for the study of flowers-and-birds paintings. The woodcut of flowers and birds is a form of woodprint which is same as a pure colored style of flowers-and-birds paintings in its expression and includes all pieces of work created using wood-engraving techniques. In this study, the woodcut of flowers and birds is considered as including both of the simple flowers-and-birds paintings printed from woodblock and the ones colored in specific styles on the woodblock prints. This study focuses on the Chosun Period compared to other periods in the number of available pieces of flowers-and-birds woodcut. To examine their characteristics, it categorizes those woodblock prints into flowers-and-birds woodcut for space decoration, book, flowers-and-birds woodcut, writing paper with flowers and birds, envelopes with flowers and birds, and character paintings with flowers and birds according to the purposes for which they were used and into beast woodcut and floral woodcut according to what is the subject matter used with. Mostly, the flowers-and-birds woodcut for space decoration-in other words, produced for the purpose of decorating everyday living spaces-engraves the outlines forming its frame and the patterns of trees, flowers, birds, waves, and rocks infine lines emphasizing their characteristics, texture, and shapes and has a style colored with a brush on the engraving. The book flowers-and-birds woodcut is divided into two main types: One reveals its subject through its used subject matters, and the other focuses on documentary and decorative characteristics. When categorized as wiring paper or an envelope, most pieces of woodcut contain flowers and birds as their main subject matters. In particular, they were created as part of the way to express one's own unique personality, so there were many dilettantes who enjoyed working on them. Since most bear a engraver's signature, it is not difficult to infer when and where they were created and to find out information about their users. Shown in character paintings, flowers and birds are printed from their woodblock patterns engraved in black-colored letters. Their bold contrast of black and white makes a strong visual impression, and the rare overlaps between subject matters gives a weak sense of spatiality, but a strong sense of planarity. In the categorization based on the used subject matters, most of the floral woodcut works discovered have been made for a decorative purpose rather than with an incantatory intention, while a significant number of beast woodcut works with flowers and grass as their main subject matters seem to have come from an incantatory intention, even though they bear a decorative purpose in part. In general, the woodcut of flowers and birds is not a simple woodblock engraving print with a single color, but a piece of work colored and finished with a brush on the print. This way of creation would probably be attempted to avoid having to draw a rough sketch whenever it was produced in large quantities. This serves as a main factor that makes the woodcut distinct from the pure-colored paintings of flowers and birds. The patterns printed from the engraving give the iconographic contour accuracy and definition so that undesired expressions can be minimized. And the woodblock-printed book is planned precisely, but not created temporarily or impromptu, so the overall iconographic composition can maintain balance and stability. Therefore, the finished work could be equipped with refinement and delicacy, although there might be limits in liberal expressions. These are some of critical features shown in the woodcut of flowers and birds, which are why the woodcut works are balanced and stable in their iconographic composition. So far, this study has focused on the flowers-and-birds woodcut, which has been seldom discussed in the existing studies, reviewing its meanings and historical background as well as types and characteristics. Most of difficulties in conducting the study came from the lack of studies on the woodcut and the shortage of its remaining works. If this study leaves something to be desired, the reason is that those difficulties acted as obstacles to a comprehensive and detailed discussion.

A persistent left superior vena cava (PLSVC) is the most common thoracic venous anomaly. It is a persistent remnant of a vessel that is present as a counterpart of normal right-sided superior vena cava(SVC) in early embryological development but normally disappears later. Its diagnosis can be confirmed by many noninvasive and invasive tests, or it is incidentally diagnosed at insertion into the left subclavian or jugular vein or thoracic surgery. If it is not associated with other congenital cardiac anomalies, it is usually asymptomatic and hemodynamically insignificant. We describe the chest radiograph and CT findings of bilateral SVC with drainage to left superior intercostal vein, hemiazygos, azygos vein and right SVC, and no connection of coronary sinus.

Purpose: The purpose of this study was to assess the height change of graft bones in a long-term follow-up after maxillary sinus floor augmentation procedures and compare the difference between xenografts and synthetic material. Materials and Methods: The subjects comprised 28 patients (62 implants) who underwent sinus floor augmentation using the lateral window technique and staged implantation. Panoramic radiographs of the 28 patients were collected immediately after implantation and at follow-up. Results: Changes in the grafted bone height showed a statistically significant decreasing tendency with time in both groups. However, there was no significant difference between the groups. Conclusions: Both xenogeneic bones and synthetic bone substitute materials were resorbed with time but maintained their shape and properties after 10 years. Therefore, both materials are suitable for sinus augmentation and biphasic calcium phosphate, a synthetic bone substitute, has shown predictable stability in sinus augmentation during long-term follow-ups.

<P><I>Background</I>. Microarrays enable high-throughput screening (HTS) of disease-related molecules, including important signaling proteins/peptides and small molecules that are in low abundance. In this study, we developed a multiplex blood bank screening platform, referred to as the Hi3-1 assay, for simultaneous detection of human immunodeficiency virus 1/2 (HIV 1/2) and hepatitis C virus (HCV). <I>Methods</I>. The Hi3-1 assay was tested using four panels (Panel 1, <I>n</I> = 4,581 patient samples; Panel 2, <I>n</I> = 15 seroconversion samples; Panel 3, <I>n</I> = 4 performance samples; and Panel 4, <I>n</I> = 251 purchased positive control samples), and the results were collected by the Department of Laboratory Medicine, Korea University Medical College, Republic of Korea. The present study compares the sensitivity of the multiplex detection platform for both HIV and HCV using a sol-gel based microarray, which was based on a reference test (Architect HIV Ag/Ab Combo and Architect anti-HCV assays), in Korean patients. <I>Results</I>. The sensitivity of the multiplex detection platform for both HIV and HCV was 100%, and the specificity was 99.96% for HIV and 99.76% for HCV, which is equivalent to that of the reference test. <I>Conclusion</I>. We have successfully applied a novel screening technology to multiplex HIV and HCV diagnoses in a blood bank screening test.</P>

연구배경 : 객혈은 원인은 매우 다양한 비록이적인 증상으로, 원인을 알 수 없거나 반복적으로 계속되는 경우 원인 병소를 찾기 위해 가장 널리 이용되는 진단법이 굴곡성 기관지경검사이다. 특히 기관지경은 객혈의 원인중 꼭 감별해야 할 질환의 하나인 폐암의 조직학적 진단을 위해서도 필수적인 검사라고 생각된다. 방법 : 객혈로 기관지경을 시행받은 479명의 환자들을 대상으로 임상적인 조사를 하였다. 결과 : 1) 결핵의 원인질환으로는 활동성 폐결핵이 가장 많았고 다음으로 만성기관지염, 폐암, 그리고 기관지확장중의 순이었다. 2) 객혈 환자의 기관지경검사상 진단은 기관지염, 활동성 폐결핵, 그리고 폐암의 순이었다. 3) 기관지경상 출혈부위를 찾은 경우는 전체의 47.2%이었고, 이중 좌엽 및 우엽이 비슷한 발생빈도를 보였으며 특히 양측 상엽에서 많이 관찰되었다. 4) 혈담을 유발시키는 주요 원인질환은 만성기관지염, 활동성 폐결핵 그리고 폐암 등이었고 1일 200mL이상 대량객혈의 주요 원인질환은 활동성 폐결핵, 기관지확장증 및 폐국균종 등이었다. 5) 원발성 폐암 환자군과 비폐암 환자군 간의 임상적 특성을 구분하여 본 결과 연령이 증가할수록(특히 50세 이후), 흡연력이 있는 경우, 그리고 혈담이 한달 이상 지속되는 경우 폐암으로 진달될 가능성이 높다고 판단되었다. 결론 : 이상의 결과로 객혈 환자에 대한 굴곡성 기관지경검사는 객혈의 원인 진단에 있어 필수 불가결한 검사법임을 알 수 있었다. Background : Hemoptysis being a nonspecific symptom often presents a diagnostic dilemma, requiring the aid of even flexible bronchofiberscopy, a novel approach, for disgnosis, especially in the cases where hemoptysis attack is repetitive or where diagnosis is tentative at best. Bronchoscopy is essential for pathologic diagnosis of lung cancer, which must be differentiated from other causes of hemoptysis. Methods : The authors evaluated a total of 479 patients who underwent bronchoscopy for the purpose of diagnosis of hemopysis. Results : 1) Active pulmonary tuberculosis was the most common cause of hemoptysis, followed by chronic bronchitis, lung cancer, and bronchiectasis. 2) The most common diagnosis by bronchoscopy was bronchitis, followed by active tuberculosis, and lung cancer. 3) It was possible in 47.2 percent of cases to identify bleeding points on bronchoscopy. The bleeding sites were most frequent in both upper lobes without predilection for each lung. 4) The most common cause of blood-tinged sputum was chronic bronchitis, active tuberculosis, or lung cancer, whereas massive hemoptysis i.e., more than 200mL of blood a day, was the result of active tuberculosis, bronchiectasis, or aspergilloma.5) Advanced age (especially more than 50 years), history of smoking or more than one month of blood-tinged sputum were significantly more common in the patients with than without lung cancer. Conclusion : Flexible bronchofiberscopy is essential for the diagnosis of underlying causes of hemoptysis. The high incidence of active tuberculosis and tuberculosis-related diseases in our patients seems to reflect this hospital being a tertiary care center to which often the problem cases are referred.
