  • Five hundred sixteen isolates of Botrytis elliptica were isolated from infected leaves of Lilium longiflorum from Kangwon alpine areas in Korea during tile seasons from 1998 to 2000 and resistance of these isolates against some fungicides were examined. The isolation frequency of phenotypes resistant to benomyl, procymidone, and diethofencarb were 90.1, 32.4, and 40.9%, respectively. The isolates were divided into six phenotypic groups; RSS, RRS, SSR, SRR, RSR and RRR, representing sensitive (S) or resistant (R) to benzimidazole, dicarboximide, and N-phenylcarbamate fungicides in order. The percentage of six phenotypes were 40.7, 8.5, 7.2, 2.7, 19.8, and 21.1%, respectively. The RSS phenotype was the most frequently isolated, and tile SRR consisted of the extremely minor populations. In comparison studies on tile overwintering ability of each phenotype in relation to the others, the most frequently isolated RSS and SSR had the higher fitness ability than the less frequently isolated RSR, SRR, and RRR. Recently, population increase of tile RSR and RRR phenotypes may have resulted from the increased applications of the mixture of carbendazim and diethofencarb to control benzimidazole-resistant B. elliptica since 1998. The results of this study indicate that careful application of the fungicides is necessary to achieve effective control of leaf blight on lily in Korea.

  • 스마트그리드는 기존의 전력시스템에 ICT 기술을 융합하여 에너지 공급자와 소비자, 서비스 제공자가 실시간으로 상호작용할 수 있는 형태의 차세대 전력망을 의미하는 것으로, 최근 대두되고 있는 에너지 위기를 타개하기 위한 중요한 솔루션 중 하나로 인식되고 있다. 그 중에서도 특히 AMI 시스템은 다양한 부가서비스 제공을 가능케 하는 스마트그리드의 핵심요소로 주목받고 있다. AMI 시스템은 그 적용범위가 광범위하고 대부분의 시스템 구성 기기가 물리적 접근이 비교적 용이한 위치에 설치되어 물리적 공격 및 사이버 공격에 대해 비교적 취약한 특성을 띤다. 이러한 보안 위협에 대응하기 위해 DLMS/COSEM 및 국내 지능형전력량계-제2부 표준에서는 지능형전력량계가 갖추어야 하는 다양한 보안기능에 대해 정의하고 있다. 하지만 각 보안기능에 대한 세부 내용을 상기 표준에서 모두 정의하고 있는 것은 아니어서 이에 대한 검토 및 논의가 필요하다. 본 고에서는 DLMS/COSEM 표준과 지능형전력량계-제2부 표준에서 정의하고 있는 보안 기능에 대해 살펴보고, 상기 표준에서 정의하고 있지 않은 보안 기능 중 지능형전력량계 유지보수를 위한 안전한 현장접근 방안에 대해 제안한다.

  • Diabetes mellitus type 2 is a metabolic disorder that is characterized by hyperglycemia (high blood sugar level) in the context of insulin resistance and relative lack of insulin. Recently, much scientific evidence has shown that the risk of diabetes mellitus type 2 could be reduced by dairy intake. A significantly strong relationship has been noted between this disease and dairy intake. In particular, from the different types of fat in dairy foods that were reported to have a beneficial impact, low-fat dairy foods have been found to have the best effect with respect to reducing the risk of diabetes mellitus type 2. Therefore, the role of specific components of dairy foods, such as calcium, vitamin D, dairy fat, and trans-palmitoleic acid, which could be responsible for this effect and for the positive effect of dairy foods in obesity and metabolic syndrome, needs to be identified. There is a strong and relatively consistent body of accumulating evidence indicating that dairy foods may significantly reduce the risk of diabetes mellitus type 2, likely in a dose-response manner. Dairy recommendations should be an essential part of public health guidance, and identifying strategies to increase dairy food consumption to optimal levels is of utmost importance. Hence, this review summarizes various positive effects of dairy foods with respect to reducing the risk of diabetes mellitus type 2, based on available evidence, and discusses the need for further research on preventing or decreasing the risk of diabetes mellitus type 2.

  • This study was designed to evaluate the antidiabetic effect of mulberry fruits using insulin-dependent and/or non-insulin-dependent diabetes mellitus animal models. The administration of mulberry fruit did not affect either body wight or blood glucose level in the normal ICR mice and streptozotocin induced-type I diabetic mice group. In second experiment, prolonged mulberry fruits treatment did not significantly attenuate the blood glucose level in type I diabetes induced by streptozotocin. In third experiment, the antidiabetic effect of mulberry fruits have been investigated using type II diabetes animal model that was induced by administration of streptozotocin to 2-day-old rats. Significant decrease in blood glucose level was observed in prolonged mulberry fruits treated group. In these treated group, the weight of liver significantly decreased than that of control group. In fourth experiment using KK mice showing genetical type II diabetes mellitus, glucose tolerance has been significantly recovered in mulberry fruits treated group but not in control group. In conclusion, prolonged administration of mulberry fruits significantly reduced the blood glucose level in type II diabetic animals. However, the blood glucose level was not significantly reduced by prolonged mulberry treatment. These data suggest that mulberry fruits can be developed as functional food that has effect on the insulin-independent diabetus mellitus(type II daibetus mellitus).

  • Diabetes Mellitus (DM) is a syndrome accompanied with the abnormal secretion or function of insulin, a hormone that plays a vital role in controlling the blood glucose level (BGL). Type land 2 DM are most common form and the prevalence of the latter is recently increasing, The aim of this article was to assess whet her Type 2 DM could act as a predisposing risk factor on the pulpo-periapical pathogenesis. Previous literature on the pathologic changes of blood vessels in DM was thoroughly reviewed. Furthermore, a histopathologic analysis of artificially-induced periapical specimens obtained from Type 2 diabetic and DM-resistant rats was compared. Histopathologic results demonstrate that the size of periapical bone destruction w as larger and the degree of pulpal inflammation was more severe in diabetic rats, indicating that Type 2 D M itself can be a predisposing risk factor that makes the host more susceptible to pulpal infection. The possible reasons may be that in diabetic state the lumen of pulpal blood vessels are thickened by atheromatous deposits, and microcirculation is hindered, The function of polymorphonuclear leukocyte is also impair ed and the migration of immune cells is blocked, leading to increased chance of pulpal infection. Also, lack of collateral circulation of pulpal blood vessels makes the pulp more susceptible to infection. These decrease the regeneration capacity of pulpal cells or tissues, delaying the healing process, Therefore, when restorative treatment is needed in Type 2 DM patients, dentists should minimize irritation to the pulpal tissue un der control of BGL.
