저자들은 인슐린 비의존형 당뇨병 환자에서 통증성 구강내 미란 및 전신성 수포성 미란을 동반한 심상성 천포창 1예를 경험하였기에 문헌고찰과 함께 보고하는 바이다. Various skin conditions such as diabetic dermopathy, necrobiosis lipoidica diabeticorum, bullosis diabeticorum, granuloma annulare occur frequently in diabetes, although common lesions may be associated by chance. Pemphigus vulgaris(PV) is a blistering skin disease seen predominantly in elderly patients. This disorder is characterized by the loss of cohesion between epidermal cells with the resultant formation of intraepidermal blisters. These blisters rupture easily, leaving denuded areases that may crust and enlarge peripherally. In half or more of patients, lesions begin in the mouth: approximately 90% of patients have oromucosal involvement at some time during the course of their disease. But the relationship of this disorder with diabetes is not clear. We experienced a case of pemphigus vulgaris associated with NIDDM in 67 years old woman who was admitted due to painful oral ulcer and control of blood glucose, so we present this case with a review of literatures.
Life Cycle CO<sub>2</sub> Emission Assessment for Non-Steam Curing Precast Concrete
Kim, Taeh Young,Tae, Sung Ho,Yang, Keun Hyeok Trans Tech Publications, Ltd. 2014 Advanced materials research Vol.1025 No.-
<P>Researches on development of technology to reduce CO2 emission while satisfying physical properties during production of precast concrete, which is mainly applied to building structures, are necessary. Accordingly, a high early strength type mixture for which removal of precast concrete form can be done by curing at room temperature instead of steam curing in the production process of precast concrete was developed. The developed high early strength type mixture was mixed with concrete to conduct coagulation, slump, and compressive strength property tests. In addition, CO2 emission and reduction performance of non-steam curing precast concrete were assessed.</P>
A Study on Environmental Load Assessment of Early Strength Activator Blast Furnace Slag
Bok, Young Jin,Tae, Sung Ho,Kim, Taeh Young,Park, Jeong Hun Trans Tech Publications, Ltd. 2014 Advanced materials research Vol.905 No.-
<P>Development of environment-friendly building materials has recently been increasing with the use of industrial waste and by-products, but concrete containing blast furnace slag (BFS) is excellent in terms of environmental load and shows relatively insufficient early strength. Development of by-products to supplement this insufficiency is deemed necessary. Therefore in this study, an early strength activator blast furnace slag (A-BFS) was developed and environment performance of the developed A-BFS was assessed to assess environmental load (CO2). As a result, early strength was developed in mortar specimen mixed with A-BFS. When environmental load (CO2) was assessed on the mortar specimen, life cycle CO2 emission from production of 1kg of A-BFS was found to be 0.057kg-CO2/kg.</P>

Background: Ventilator-associated pneumonia (VAP) requires prompt and appropriate treatment. Since methicillin- resistant Staphylococcus aureus (MRSA) is a frequent pathogen in VAP, rapid identification of it, is pivotal. Our aim was to evaluate the utility of quantitative polymerase chain reaction (qPCR) as a useful method for etiologic diagnoses of MRSA pneumonia. Methods: We performed qPCR for mecA, S. aureus-specific femA-SA, and S. epidermidis-specific femA-SE genes from bronchoalveolar lavage or bronchial washing samples obtained from clinically-suspected VAP. Molecular identification of MRSA was based on the presence of the mecA and femA-SA gene, with the absence of the femA-SE gene. To compensate for the experimental and clinical conditions, we spiked an internal control in the course of DNA extraction. We estimated number of colony-forming units per mL (CFU/mL) of MRSA samples through a standard curve of a serially-diluted reference MRSA strain. We compared the threshold cycle (Ct) value with the microbiologic results of MRSA. Results: We obtained the mecA gene standard curve, which showed the detection limit of the mecA gene to be 100 fg, which corresponds to a copy number of 30. We chose cut-off Ct values of 27.94 (equivalent to 1×104 CFU/mL) and 21.78 (equivalent to 1×105 CFU/mL). The sensitivity and specificity of our assay were 88.9% and 88.9% respectively, when compared with quantitative cultures. Conclusion: Our results were valuable for diagnosing and identifying pathogens involved in VAP. We believe our modified qPCR is an appropriate tool for the rapid diagnosis of clinical pathogens regarding patients in the intensive care unit.

The objective of this study was to develop a method to simultaneously quantify vitamins A and E in infant formula. To determine the vitamin A and E content, vitamin A and four different vitamin E isomers (α-, β-, γ-, and δ-tocopherol) were separated by high performance liquid chromatography with a photodiode array detector using a Develosil RPAQUEOUS RP-C30 column (4.6×250 mm, 5 μm). The vitamin A and E contents in the certified reference material determined using this method were within the certified range of standard values. The limits of detection (LODs) and limits of quantitation (LOQs) for vitamin A were 0.02 and 0.06 μg/L, respectively. LODs and LOQs for the vitamin E isomers ranged from 0.20 to 0.55 and from 0.67 to 1.81 μg/L, respectively. Linear analyses indicated that the square of the correlation coefficient for the vitamin A and E isomers was 0.9997-0.9999. The recovery of vitamins ranged from 96.69 to 97.79%. The results demonstrate that this novel method could be used to reliably analyze vitamin A and E content in infant formula.
