Musculoskeletal ultrasound (MSUS) has newly evolved by the mechanical improvement of the machine over past several years, becoming a part of imaging techniques for the evaluation of variable diseases in the musculoskeletal system. MSUS has proven diagnostic superiority in pathologies including rotator cuff disease of the shoulder, lateral epicondylitis of the elbow, diseases of the peripheral nerve, detection of intra-articular loose bodies and soft tissue foreign bodies, and in evaluating small superficial soft tissue tumors such as ganglion, epidermoid cyst, and glomus tumor. Besides, MSUS is very useful for obtaining tissue or fluid via percutaneous fine needle aspiration and/or biopsy for the histopathologic diagnosis. Combining MSUS with MR would play a great role in the field of the diagnostic imaging of the musculoskeletal system. The MSUS examiner should have the knowledge of cross-sectional anatomy, and of the mechanical and physical properties of ultrasound in order to interpret the ultrasound findings accurately and properly, and to avoid diagnostic errors due to variable artifacts subsequently. The goal of this article is to introduce the capabilities of MSUS in certain kinds of clinical situation and to familiarize the reader with MSUS. For the purpose, author intends to describe this article according not to the disease-, or organ-based, but to the clinical problem-based format.

The objective of this paper is to examine the legal framework governing the import and export of grain in China, a pivotal factor in shaping policies aimed at stabilizing South Korea's foreign trade and grain imports. Through this analysis, it is observed that China's foreign trade system, governed by the Foreign Trade Act, exhibits a notable absence of clear delineation regarding the scope and responsibility for the delegation of authority to foreign trade management agencies. In contrast, Korea's Foreign Trade Law, along with its enforcement decree and management regulations, explicitly outlines the scope and responsibilities pertaining to the delegation of authority to foreign trade management. However, in the case of China's revised Foreign Trade Law, there exists a lack of precision in specifying the delegation of authority to foreign trade management. This creates a potential for discretionary intervention by local governments or other administrative bodies. While China's legal system concerning grain imports and exports aligns with WTO regulations in its institutional framework, attention is warranted due to the vagueness in laws or regulations, as well as the presence of irrational and non-transparent procedures during system operation. As conclusion remarks, while China's legal structure related to grain imports and exports conforms to WTO guidelines overall, the identified issues such as legal ambiguity and non-transparent procedures underscore the need for caution. To safeguard against potential challenges in future trade interactions with China, proactive measures are crucial to address these concerns.

Purpose : The aim of this study was to evaluate the latest tendency of esophageal foreign body's extraction and to obtain a consensus from recent trends of indications and techniques of flexible endoscopy of esophageal FB in children. Methods : We retrospectively reviewed medical records of 127 cases with foreign bodies in esophagus at Dept. of Pediatrics and Otorhinolaryngology, Gyeongsang National University Hospital (GNUH) from Jun, 1987 to July, 2001. They were divided into two groups by the kinds of endoscopy : flexible endoscope(66 cases) or rigid endoscope(61 cases). Rigid endoscopy was performed under general anesthesia at Dept. of Otorhinolaryngology but flexible endoscopy was performed without general anesthesia or sedative drugs(midazolam or diazepam). Results : An annual number of cases of two groups were similar from 1991 to 1998. But from 1999, flexible endoscopy was performed actively. Asymptomatic cases were frequently observed in flexible endoscopy(28 cases/66 cases) but swallowing difficulties were frequently observed in the rigid endoscopy group(25 cases/61 cases). Other symptoms were vomiting, irritability, chest discomfort and abdominal pain. The total number of cases with underlying disease(esophageal stenosis, cerebral palsy) was 8. The total number of cases with complications (erosion, ulcer, bleeding, perforation) was 11. The above cases were not correlated between the two groups. In 55 cases(83.3%) of the flexible endoscopic group and 53 cases(86.8%) of the rigid endoscopic group, foreign bodies in the esophagus were removed within 24 hours. Conclusion : We could not find any benefit in rigid endoscopic technique. Flexible endoscopic FB removal can be performed safely and effectively in children by an experienced endoscopist.

An important change started in knitwear fashion in the 1980s. Advanced designers in Japan began to provide a new interpretation on knitwear, and seamless knitwear based on computerized machinery appeared. Knitwear fashion showed differences starting the 1980s due to this change. In this regard, the study aimed to analyze knitwear fashion after the 1980s where the contemporary knitwear experienced changes to define characteristics of modern knitwear fashion and examine its inherent formative nature. Designs for 30 years from 1980s up to date have been analyzed by 10 years in order to identify the characteristics of knitwear fashion over time. In particular, formative characteristics of modern knitwear fashion have been analyzed in more depth with a focus on the period from 2001 through 2010 by narrowing the whole period. Insufficient domestic literatures and visual materials led the study to mostly use foreign books and internet sites. Insights of 7 professionals who have engaged themselves in knitwear industry over 10 years have been incorporated into this study, which will enhance the reliability of the formative analysis. As a result, the data have been organized into three tools of analysis, including exposed bodies, transformed bodies and natural bodies from the perspectives of expression and silhouette of body, and the features of flexibility, industrial artistry, innovation and sensuality have been highlighted in terms of formativeness. In this regard, it has been confirmed that the formative nature found in the knitwear fashion exists in the scope of the formative nature in the embryonic period of the knitwear fashion. It means that the formative nature of knitwear fashion contains perpetuity that transcends an age.

Violence in our society, combined with improving transport system, resulted in increased numbers of patients with cardiac wounds reaching the hospital alive. Most patients with penetrating cardiac injury, rather than blunt injury, present with a syndrome of either hemorrhagic shock or cardiac tamponade. And they should be operated upon as soon as possible. Often the atrioventricular valves and other important cardiac structures are also damaged by the penetrating instruments or missile. Both intracardiac communications and atrioventricular fistulas may result in significant left-to-right shunts accompanied by congestive heart failure, necessitating surgical correction. Usually, retained cardiac foreign bodies, which are almost always bullets or fragments of missiles, may lie within a cardiac chamber or in the myocardium. Emboli of bullets or other missiles from distant sites to the right side of the heart are numerous enough to require attention. Recently we experienced a case with intracardiac foreign body due to penetrating cardiac injury. A 19 year-old man was admitted to our hospital due to penetrating anterior chest wound by iron segment. The roentgenogram of the chest revealed a radio-opaque metallic shadow in left lower chest around the cardiac apex, mild blunting of left costophrenic space, but no cardiomegaly. During operation the foreign body was noted to be present in the cardiac chamber by the portable C-arm fluoroscopy. But during the manipulation it moved into left inferior pulmonary vein from left ventricle by way of left atrium. So we could manage to remove it from left inferior pulmonary vein by direct approach to the vein. It was iron segment, sized 0.lcm x0.6cmx0.5cm, with sharp margins. The patient had an uneventful postoperative recovery except for chylopericardium and was discharged.

Aspergillus causes a variety of clinical syndromes in the lung including tracheobronchial aspergillosis, invasive aspergillosis, chronic necrotizing pulmonary aspergillosis, allergic bronchopulmonary aspergillosis, and aspergilloma. Aspergilloma usually results from ingrowths of colonized Aspergillus in damaged bronchial tree, pulmonary cyst or cavities of patients with underlying lung diseases. There are a few reports on endobronchial aspergilloma without underlying pulmonary lesion. We have experienced a case of endobronchial aspergilloma associated with foreign body developed in an immunocompetent patient without underlying lung diseases. A 59-year-old man is being hospitalized with recurring hemoptysis for 5 months. X-ray and computed tomography scans of chest showed a nodular opacity in superior segment of left lower lobe. Fiberoptic bronchoscopy revealed an irregular, mass-like, brownish material which totally obstructed the sub-segmental bronchus and a foreign body in superior segmental bronchus of the lower left lobe. Histopathologic examinations of biopsy specimen revealed fungal hyphae, characteristic of Aspergillus species.

Foreign body aspiration (FBA) is a common accident in young children. Undiagnosed and retained foreign bodies may result in severe early and late complications such as asphyxia, pneumonia, atelectasis and bronchiectasis. Moreover, because it can mimic bronchiolitis, croup or asthma, an accurate history and a high index of suspicion are of paramount importance for early diagnosis. With our experience on bronchial FBA initially misdiagnosed as acute bronchiolitis, we emphasize that a minute radiological finding should not be neglected and a repeat chest radiograph may be helpful when the initial study shows normal findings. Multidetector computed tomography is a very useful noninvasive diagnostic modality for FBA.

In spite of importance of safety issues in community sport, little concerns have been paid to the sport safety policy. Governing bodies and individuals involved with the facility management have a responsibility to manage the risks at acceptable levels. For sports injury prevention interventions, the safety policy of sport facilities should be made to provide a structured framework which can be implemented at community sport. Hence, the current study is to identify the safety issues and to generate the policies that assist to conduct the systematic safety management at sports facilities. For this, the current study analyzed two cases from Japan and Germany. The study reviewed multiple pieces of literature including journal publications, political reports, and media coverage. Through review, the study analyzed the organizational structure, legal systems, and political stance of the safety management of sport facilities in Japan and Germany. The results proposed the following issues. First, law needs to be enacted to establish the control tower where has a responsibility to develop the safety manual and system. Second, local organizations need to be established to educate individuals working in sport facilities and inspect the facilities. Further political issues were discussed for safety management in Korea sport facilities.

With the exception of gun shot wound, the incidence of penetrating injury of face and neck areas nonorganic foreign bodies is relative low. But the diagnostic evaluation and therapeutic management of penetrating facial wounds need careful decision, when the anatomic proximity of the major vessels and nerve is considered. Penetrating facial trauma with concomitant vascular injury present challenging problems, the immediate complication of this vascular injury are severe bleeding, hematoma formation, shock, obstruction of airway. The vascular injury is conformed by angiography. In this report, a industrial tool(long tack) fired by explosive air is penetrated into face and to neck. In angiograms penetrating injury of the vertebral artery is detected. We performed the embolization of the vertebral artery with coils and manual removal of the foreign body without any complication was followed.

Services, despite the difficulty of its exact definition, can be defined as deeds, efforts, or performances by economical bodies, attributing to four unique characteristics - intangibility, inseparability, heterogeneity, and perishability. This study aims to research the global competition and problems of the local professional services, especially educational services and health services, and to suggest some devices for increasing the exportation of both educational services and health services. Educational services and health services were reserved in the multilateral negotiation to open the WTO parties' markets because of its national public benefits. But it is indispensable to open our local market by the bilateral FTA negotiation. Legal restrictions, therefore, related to both education and health should be erased according to the basic rule of the market competition, and it is advisable to control the national public benefit of these services by enacting the different legal systems. For recovering from minus balance of payment in the educational services or health services, furthermore, it is necessary to drive rather some offensive exporting policies than the defensive policy against supply from the foreign countries. In conclusion, the korean Foreign Trade Act and other relative acts should be revised, and both educational services and health services should be contained within the definition of "the international trade" for the governmental benefits of supporting the services exportation.
