Crohn`s disease is a chronic inflammatory bowel disease that can involve the whole gastrointestinal tract. The orofacial manifestation of Crohn`s disease, which is rare, can develop irrespective of intestinal involvement. These orofacial lesions are often misdiagnosed as simple oral ulcers. Corticosteroids are the mainstay of therapy for orofacial Crohn`s disease. However, infliximab, the chimeric monoclonal antibody to tumor necrosis factor-α, is now considered as a primary treatment because of the disease`s relatively high rate of steroid resistance. We present a case of deep oral ulcer and periorbital swelling in a 65-year-old woman. She was diagnosed with intestinal Crohn`s disease 7 years ago, which was in remission after treatment with an immunosuppressive agent (azathioprine). The patient was given the diagnosed with orofacial Crohn`s disease and successfully treated with infliximab. (Korean J Gastroenterol 2012;59:437-440)

Background : In recent years, gonorrhea has been panedemic and remains one of the most commom STDs in the world, especially in developing countries. Objective & Methods: For the detection of a more effective therapeutic regimen and assessing the prevalence of PPNG, we have been trying to study the patients who have visited the VD Clinic of Choong-Ku Public Health Center in Seoul since 1980 by means of the chromogenic cephalosporin method. Results: In 1996, 139 strains of N. gonorrhoeae were isolated, among which 53(39.0%) were PPNG. Conclusion: Our results suggests that after a peak of 74.3% in 1993, the prevalence of PPNG in Seoul is gradually declining.

This paper reviews the literature on the problem of information overload. The literature reveals that although the problem of information overload has existed for many years, in recent years the problem has become more widely recognised and experienced. Information overload has been defined as the receipt of more information than is needed or desired to function effectively and further the goals of an individual or organization. More formally, receipt of undesirable or non-relevant messages that result in an economic loss for the recipient represents information overload. Information overload costs businesses and individuals valuable time, effort and additional resources. Information overload has been exacerbated by the rapid advances made in information and communication technology A Theme stressed in the literature is the paradoxical situation that, although there is an abundance of information available, it is often difficult to obtain useful, relevant information when it is needed. Some solutions put forward to reduce information overload are; time management, information literacy, personal information management, information quality filters, e-mail etiquette policies, knowledge organization, maintaining currency, vocabulary control, information design, the role of information specialist, and software solutions such as intelligent agents, filtering, and customization of search results.

Successful alveolar ridge augmentation by distraction osteogenesis method has been reported previously. There are several types of devices for alveolar ridge augmentation. In this paper, a new intraoral distraction device was used on the severe atrophic mandible in order to distract an alveolar ridge vertically in 5 patients. Mean amount of distracted alveolar ridge was 7.4㎜ (5∼9.5㎜). Dental implants were placed in the distracted alveolar bone and good osseointegration was obtained in all patients. Mean follow up period is 2years 6months (7months∼4years 9months). No complications, such as infection or resorption was observed in all patients. Alveolar ridge augmentation by gradual distraction seems to be a safe, simple and reliable procedure.

The new efficient square electro-magnetic chuck, which is using for the clamping devices of grinding machine, is developed in this study to improve the convenience of grinding work and to give the workpiece high parallelism and flatness without scratch or deformation. The recommended structure of magnetic cells are updated to find the most superior magnetic characteristics by using the finite element analysis and sample prototyping, The analyzed results are retrofitted to solve the drawbacks of previous models step by step by considering the characteristics such as magnetic fields, strength, distribution, and thermal deformations of magnetic chuck. Finally the most recommended models is designed to satisfy the KS specifications with commercial magnetic chuck, and the prototype chuck with this dimensions and structures is manufactured, it is also analyzed the overall characteristics of magnetic chuck and is performed the experimental investigations whether the KS specifications are satisfied.

Circuit board assemblies experience various mechanical loadings during assembly and in actual use. The repeated cyclic bending can cause electrical failures due to circuit board cracks, solder interconnects cracks, and the component cracks. This paper presents a cylic bending tester developed especially for evaluating the reliability of board level flip chips under the repeated cyclic bending. The tester employs the concept of 4-point bending test and complies to JEDEC standard No. 22B113 that is intended to evaluate and compare the performance of surface mount electronic components in an accelerated test environment. The performance of the tester will be estimated through the cross check of the test results in the future work.
