Together with the development of ubiquitous computing technology and robot technology, intelligent type robots are being utilized in many areas and the range is expected to become wider and wider. Among many service robots, the educational robots are being diversely studied in the field with the concept of r-Learning. Presently, teaching assistant robots require a lot of HRI studies prior to their practical use in the very near future and are not sufficient yet. Especially, the reactions of students based of the styles of robots (e.g. serious robot, playful robot) are very important in producing robot contents but there has been no case study on them. Therefore, in this study, the appearance of the IROBI was changed to become a teaching assistant robot and was used to test and compare elementary school students' interest, achievement and concentration depending on the styles of robot (playful, serious). The results showed that the interest was high in the group that had studied with the playful robot. The achievement however, did not show significant relations with the style of robot and that the concentration was high in the group that had studied with the serious robot.

Leflunomide is a new disease modifying anti rheumatic drug (DMARD) for the treatment of active rheumatoid arthritis. Its mechanism of action differs from other DMARDs in that it inhibits the de novo pyrimidine synthesis by inhibiting dihydroorotate dehydrogenase and therefore prevents the proliferation of activated lymphocytes. As it has been prescribed worldwide, there is a great deal of much concerns regarding its potential adverse effects. Because leflunomide has an active metabolite with a long elimination half-life of approximately 2 weeks, serious adverse reactions may occur even after the leflunomide treatment has been stopped. The profile of serious reactions includes liver dysfunction, hematological disorders, severe skin reactions and respiratory dysfunction. Respiratory dysfunctions with leflunomide therapy are very rare and its incidence is lower than that of methotrexate therapy. However, there are reports in Japan showing that 5 patients died of interstitial pneumonitis and another 11 patients developed serious lung complications associated with leflunomide. This suggests the possibility of fatal respiratory toxicity of leflunomide. There are no reports of interstitial pneumonitis associated with leflunomide in Korea. We report a case of a 62-year old woman who developed interstitial pneumonitis, which might have been induced by leflunomide during the treatment of rheumatoid arthritis.

Purpose: Mass can compress around tissue and cause deviation of normal anatomical structures. Often, mass grows toward neurovascular pedicle and encircles depending on the nature of mature mass. Neglecting neurovascular involvement of the mass is a serious problem not to be overlooked. Authors have performed microscopic approach regarding mass involving the neurovascular pedicle in the hand. Materials and Methods: From January 2007 through February 2012, retrospective analysis for nine cases of mass involving neurovascular pedicles was done. Patients were evaluated preoperatively by ultrasonography or MRI and checked intraoperative finding. Masses were evaluated by site, preoperative evaluation, involved neurovascular pedicle, histopathologic diagnosis, complication, and recurrence. Results: The site of mass involving neurovascular pedicles was 4 cases on the wrist, 2 cases on the palm, 2 cases on the finger, 1 case on the hand dorsum. Involved neurovascular pedicles were 3 radial arteries and nerves, 3 proper digital arteries and nerves, 1 radial artery, 1 superficial branch of radial nerve, 1 common digital artery and nerve. The histopathologic diagnosis of mass were 3 ganglions, 2 giant cell tumors, 2 epidermal cysts, 1 fibroma, and 1 benign spindle tumor. There were 2 cases of recurrence and secondary excisions were performed. Conclusion: Neurovascular pedicle injury can lead to serious complication like sensory and motor disorders, distal part ischemia, and so on. In case of mass suspected neurovascular invasion, accurate preoperative evaluation such as ultrasonography or MRI is necessary. To prevent any neurovascular related complication during mass excision, delicate surgical technique using a microscope becomes essential.

Purpose: This paper is aim to report that menopausal disorder can be effectively diagnosed and treated by referring to the life event stress of patient. Methods: Researchers got a grip on the life event stress of patient by using medical examinations by interview and compared the conditions of patient before and after treatment by using Kupperman's Index. The prescription of the Gamidangguisu-san hap samhap-tang( Jiaweidangguixu-san he sanhetang) and the Gamisoyo-san (Jiaweixiaoyao-san) and the acupuncture therapy and the moxibustion therapy were used for the treatment. Results: The serious musculoskeletal systemic pains, which includes back pain, lumbago, and myalgia, and other menopausal troubles were improved remarkably. Conclusion: The menopausal disorder could be caused by not only the change of hormone but also complex factors of environmental matters which includes social cultural surroundings, mentality etc. Therefore the life event stress could be one of critical factors of menopausal disorder. The diagnosis and treatment considering the life event stress could be effective method to relieve patient's menopausal disorder.

To operate a large structure or a high-rise building, elevator is essential. Nevertheless, elevator breakdowns or accidents have been consistently reported. When the accidents are not serious, the records are not reported and cumulated in the Korea Elevator Safety Agency. Additionally, in case of replacement or repair of the parts of elevator, conflicts about the person responsible for the expense of the replacement or repair are frequently occurred. However the record of accidents is not decreasing and the conflict about the fund of elevator repair is serious. So, it is needed to reduce the elevator accidents or malfunction, the operation stop of the elevator, the conflict between building owners and users. Therefore, in this study, the elevator maintenance procedures during defect liability period, the notification procedure in case of breakdown or accident elevator, the direction of elevator maintenance contracts, the direction of the elevator inspection were suggested.

Foreign bodies in the esophagus are common in the field of otolaryngology. They are usually due to ingestion of a coin or two, especially in the cases of children. Almost always, a coin in the esophagus can be easily removed under esophagoscope. However, untoward complications have not infrequently ensued. The authors have recently experienced an interesting case of foreign body in the mediastinum. It was found to be a 50-Hwan coin that had remained between the tracheal bifurcation and the esophagus for 13 years without causing any serious complication. At age of 17 years, he visited ENT department of our hospital, where the coin was removed safely by trans- thoracic approach under general anesthesia. So we report this case along with literature review.

Vertebroplasty and kyphoplasty are well-known, useful techniques for the treatment of painful vertebral compression fractures. Although the risk associated with these procedures is low, serious complications can occur. Of these complications, infection is even rarer, however, when it does occur, it is difficult to manage and can become life-threatening. We describe here a case of infectious spondylitis with epidural inflammation that occurred after performing kyphoplasty in a patient who had a thoracic vertebra compression fracture. We reviewed other case and literatures. Extreme asepsis of the operating theater, screening and treatment for systemic infection prior to the procedure, as well as the use of appropriate antibiotic prophylaxis are strongly recommended when conducting kyphoplasty to prevent infection.

The Internation Maritime Organization (IMO) has required that ships other than cellular-ships which carry cargo units and other entities should be provided with a cargo securing manual. A number of serious accidents has resulted from improper stowage and insufficient securing of heavy cargo. The cargo claims caused by the accidents stated above not only reduce the number of shippers but also reduce their benefits. The following four basic safe items should be considered carefully in the carriage by sea in case of two tiers loading of heavy cargoes packed with wooden case if it is a general cargo ship. a) Safe stowing place b) Safe lashing c) Protecting crushing goods d) Adequate dunnage. All operators of cargoes must be reminded that only the proper stowge and securing of heavy cargos can prevent from the occurrence of such accidents in the future. This paper intends to analyze the unigue damage mechanism for two tiers loading of heavy cargoes on the general cargo ships encountered in the rough sea, and suggest the countermeusere to prevent the identical accidents in the future.

Treatment guidelines for postnatal cytomegalovirus (pCMV) infection in preterm have not been established yet. Neutropenia, thrombocytopenia, hepatitis, colitis, and sepsis-like disease are among the clinical manifestations, which range from moderate to serious. We present a case of autopsy diagnosed as pCMV infection in a premature infant delivered at gestational age of 24 weeks and 5 days. On the 7th and 14th days of birth, urinary CMV polymerase chain reaction samples were negative, ruling out congenital CMV infection. However, autopsy examination revealed that the patient had disseminated pCMV infection. CMV inclusion bodies were found in the majority of tissues, including the lung, liver, pancreas, breast, kidney, and adrenal gland, but not the placenta. The thymus exhibited significant cortical atrophy and T-cell immunodeficiency, possibly induced by dexamethasone treatment for bronchopulmonary dysplasia or by pCMV infection itself. If dexamethasone treatment is extended or high doses are considered, it may be beneficial to test the CMV infection status to prevent aggravation of infection. This case demonstrates that, despite the low prevalence, pCMV infection should be considered a differential diagnosis in preterm if other conditions or etiology cannot justify clinical deterioration.

This report presents a clinical case of trauma due to assault with a knife, and describes the importance of using the correct imaging modality in cases of facial penetrating trauma involving the superficial and deep anatomical planes. Penetrating wounds in the maxillofacial region are rare and poorly reported, but can result in serious complications that are difficult to resolve and may compromise the patient's quality of life, especially when large blood vessels or other vital structures are involved. Thus, it is essential to determine the extent of the affected blood vessels and the proximity of the retained object to the anatomical structures. In this case, digital subtraction angiography was the imaging modality chosen. The use of appropriate imaging examinations allows a proper map of the surgical field, reducing the chances of vascular damage during the surgical procedure.
