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.

까치복의 呈味成分에 관한 資料를 얻고자 核酸關聯物質, 유리아미노산, TMAO, TMA, betaine 및 총 creatinine을 分析하였다. 核酸關聯物質 중 IMP가 1.9μmole/g으로서 가장 많았고, 全核酸關聯物質에 대해 39.6%를 차지하였다. 유리아미노산 중 함량이 많은 것은 taurine, lysine, alanine 및 glycine 이고, 이들 네 가지 아미노산이 전유리아미노산의 68.2%를 차지하였다. 총 creatinine�량은 194.5mg/100g으로서 엑스分窒素에 대해 63.4%를 차지하였으며, TMAO 및 betaine 함량은 微量이었다. Omission test 結果 까치복의 呈味成分은 5'-mononucleotides 및 유리아미노산이 주된 구실을 한다는 것을 알았다. Yellowfin puffer, Fugu xanthopterus(Temminck et Schlegel), is one of the most palatable fishes in Korea. However, relatively little is known about the characteristics of its taste. In this study, the taste compounds including nucleotides and their related compounds, free amino acids, trimethylamine oxide, trimethylamine, betaine and total creatinine were analyzed, and their roles in tasting activity were investigated. The amounts of IMP was 1.9 μmole/g, and the ratio of IMP to the total nucleotides and their related compounds was 39.6%. The great portion of free amino acids in the extractives of yellowfin puffer muscle was occupied by taurine, lysine, alanine and glycine in order, and their content was 79.1% of the total free amino acids. Among the organic bases, total creatinine was abundant, and its nitrogen content was 63.4% of total extractive nitrogen. According to the results of the omission test, the main constituents of the characteristic taste of yellowfin puffer could be assumed as free amino acids and 5'-mononucleotides.

In general, 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. In this paper, we report on the failure characteristics of board level flip chips under the repeated cyclic bending. We first describe a new 4-point bending tester, which is developed according to JEDEC standard No.. 22B113. The performance of the tester is then estimated through actual experiments . Test results reveal that the cracks first occur on the outer balls around 20,000 cycles and gradually propagate to the inner balls where cracks are found around 70,000 cycles.

조직의 정보과잉문제에 대한 해결방안

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.

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.

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.

A 40-years-old woman was admitted to this hospital with flank pain and high grade fever for 2 weeks. As a matter of her past history, extracorporeal shock wave lithotripsy (ESWL) was performed for treatment of renal stones 5 years ago. Her abdominal CT findings were hydronephrosis with pyonephrosis and renal stones. Antibiotics administered for 5 days had no effects on her symptom improvement. A right ureteral stricture was noticed by ultrasonography follow up. We inserted double J stent and continued antibiotics therapy for 10 days, and then her fever was disappeared and flank pain was improved. ESWL is one of the most important treatment of renal and ureteral stone. However, its complications should not be negligible including bleeding, pain, ureteral obstruction, infection and so on. Complications of ESWL can be divided into acute and chronic courses. When we treat pyelonephritis patient with past history of ESWL, possibility of ureteral stricture must also be considered. In this study we report a case of pyelonephritis caused by ureteral stricture, possibly as a chronic complication of ESWL performed 5 years earlier
