최근 유비쿼터스 기술이 가까운 미래에 새로운 기술로서 언급되고 있다. 특히 RFID 기술은 거의 모든 산업에 큰 영향을 가져올 기술로서 각광받고 있다. 따라서 현재 바코드를 뛰어 넘는 많은 정보 저장 및 추적가능의 획기적 기술 특징들을 이용하여 복잡하고 다양한 현 의약품관리 시스템의 문제점을 살피고 RFID기술 적용을 통한 개선 방향을 제시하였다. 본 연구에서는 현재와 미래 유비쿼터스의 개념과 여러 기술들을 설명하고 RFID기술의 한계와 장점을 자세히 설명하였으며, 의약품 관련 산업의 시각 차이에 의한 기술 구현의 어려움과 방안을 제시하였다. Recently, Ubiquitous Technology is referred to as new technology for the near future. RFID Technology, One of the Ubiquitous Technologies, will have a huge effect on almost all industry in technology. This technology is also having a big effect on physical distribution circulation class such as current wal-mart. In addition, many technologists expect that the technology will be widely used in the field of complicated pharmacy inventory management because it has much more capacity for data storage and massage transfer ability than bar code does. Therefore, the object of this research is to see the study trend that this technology will give us the solution to overcome the difficulty of pharmacy inventory management. And I wish to present a direction that can improve company’s inventory management system in pharmaceuticals management conforming with various kind and management law, regulation and efficiently taking advantage of RFID Technology.

Hemophagocytic lymphohistiocytosis (HLH) is a rare disorder characterized by fever, pancytopenia, hyperferritinemia, and phagocytosis of hematopoietic cells in bone marrow, liver, or lymph nodes. HLH can occur during the course of systemic lupus erythematosus (SLE), but can also be a presenting manifestation. Because development of pancytopenia occurs in less than 10 percent of SLE cases, investigation for HLH is necessary when otherwise unexplained pancytopenia persists despite adequate treatment. We experienced three cases of secondary HLH associated with SLE. Among the three patients, two patients developed HLH during the clinical course of SLE. The other patient who presented with pancytopenia was first diagnosed with HLH, and later with SLE. In her case, HLH turned out to be a presenting manifestation of SLE. We report on three successfully treated cases, and discuss the prevalence, characteristics, treatments, and prognosis of secondary HLH associated with SLE. (J Rheum Dis 2015;22:180-185)

In the present work, the fluid flow characteristics of a mixed-flow pump have beenwere investigated numerically using threedimensional Reynolds-averaged Navier-Stokes equations. The shear stress transport turbulence model and hexahedral grid system were used to analyze the flow in the mixed-flow pump. The efficiency of the mixed-flow pump was evaluated using the variation of two geometric variables related to the inlet angle of the diffuser vane. The design optimization of the mixed-flow pump was performed to maximize the its efficiency at the prescribed specific speed using a surrogate model. Latin hypercube sampling was used to determine the training points for the design of the experiment, and the surrogate model was constructed using the objective function values at the training points. The results show that the efficiency of the mixed-flow pump at the prescribed specific speed is improved considerably by the design optimization.

This study compared the quality characteristics between meat ball products in domestic market. Five types of meat ball products(T1, T2, T3, T4 and T5) were purchased in domestic market. In terms of the chemical composition, meat ball products ranged 53.92~63.45% in moisture contents. In terms of quality characteristics, T2 showed a significantly higher pH value and cooking loss than the others (p<0.05). In terms of deformation rate, T2 showed a significantly higher contraction of height than the others (p<0.05). In the panel test, T1 showed a significantly higher score in saltiness, flavor, color, appearance and total acceptability (p<0.05). Overall, meat ball products showed considerable differences in chemical composition, cooking loss, Hunter color values, and texture profile due to differences in raw materials, recipes, and weights.

Background: Secondary hemophagocytic lymphohistiocytosis (HLH) can occur during the course of systemic lupus erythematosus (SLE), but also can also be a presenting manifestation. Case1: The 13-year old girl who was diagnosed with SLE a year ago presented with fever. Since she had redness and tenderness on her left fifth fingertip, we assumed that cellulitis was the cause of fever and treated her with antibiotics. Her fever persisted, so we increased her steroid to treat SLE fiare which might have been overlooked. However, pancytopenia, hyperferritinemia and hypertriglyceridemia developed, we biopsied her bone marrow. She was diagnosed with secondary HLH and received steroid pulse therapy. Case2: The 27-year old woman presented with fever and bleeding tendency. Her laboratory results revealed pancytopenia, hyperferritinemia and hypertriglyceridemia. We biopsied her bone marrow and she was diagnosed with HLH. She had pericardial effusion, proteinuria and low serum complement level and was positive for anti-nuclear antibody and anti-double strand DNA antibody. As a result, she was diagnosed with SLE at the same time. We treated her with steroid, etoposide and cyclosporine. Case3: The 30-year old woman who was diagnosed with SLE fifteen years ago presented with fever. We suspected SLE fiare and increased her steroid. Despite treatment, she constantly had fever and her laboratory results showed pancytopenia, hyperferritinemia and hypertriglyceridemia, we gave her steroid pulse therapy and biopsied her bone marrow. She was diagnosed with secondary HLH. All three patients became afebrile and recovered from their pancytopenia after treatment. Conclusion: Since pancytopenia develops in less than 10 percent of SLE cases, the investigation for HLH is necessary when otherwise unexplained pancytopenia persists despite adequate treatment. Hereby we report three successfully treated cases, and discuss the prevalence, characteristics, treatments and prognosis for secondary HLH associated with SLE.
