食用油脂는 健康維持에 必須的인 營養素이다. 그러나 食用油脂는 脂肪을 構成하는 脂肪酸의 種類와 攝取하는 量에 따라 健康을 保衛하는 必須的인 食品의 成分이 되기도 하고 有害한 影響을 끼칠 수도 있어서 脂質代謝와 關連된 疾病 뿐만아니라 老化를 促進하고, 乳房癌, 大腸癌等의 癌發生과도 關連된 것으로 밝혀져 있다. 本 硏究는 우리生活環境에서 食用으로 接할 수 있는 10種의 油脂에 對한 免疫生物學的인 活性에서 究明한 結果 對照群인 참기름食餌群에 比해 올리브유食用群은 全般的으로 體液性 및 細胞性免疫을 有意性있게 增加시켰으나, 大食細胞의 活性과 末梢循環白血球數는 有意性없는 減少를 보였고, 動物性 油脂인 牛脂食餌群과 植物性 油脂인 옥수수기름食餌群, 들기름食餌群, 米糠油食餌群, 大豆油食餌群, 菜種油食餌群 및 고추씨기름食餌群에서는 全般的으로 體液性 및 細胞性免疫, 大食細胞의 活性 및 末梢循環白血球數를 有意性있게 減少시켰다. This study was performed to investigate the effects of edible oils and fats on the immunobiological responses in ICR male mice. Ten groups of experimental diets, such as sesame oil diet, beef tallow diet, lard oil diet, olive oil diet, corn oil diet, perilla oil diet, rice polishing oil diet, soybeen oil diet, rape seed oil diet, and red pepper seed oil diet were fed adlibitum to the ICR male mice for 27 days. The results of this study were summarized as followings. 1. Both humoral and cellular immune responses, phagocyte activity, and number of leukocytes in sesame oil group were increased. However, the increasing rate of body weight and the weight retios of spleen and thymus to body were generally decreased. 2. Hemagglutination titer(HA) and rosette forming cell(RFC) of the beef tallow group and the lard group were significantly lower than the sesame oil group(P<0.01), but the lard group significantly increased Arthus reaction and delayed type hypersensitivity(DTH)(P<0.01). 3. Arthus reaction, DTH, and RFC of the olive oil group were significantly higher than the sesame oil group(P<0.01). 4. DTH of the corn oil group was significantly higher than the sesame oil group(P<0.01) whereas phagochyte activity was significantly lower(P<0.01). But no statistically significant differences were found between the two groups in the humoral immune response. 5. HA, PFC, DTH, RFC, phagocyte activity, and number of leukocytes of the perilla oil group and the rice polishing oil group were significantly lower than the sesame oil group(P<0.01). 6. Both humoral and cellular immune responses, phagocyte activity, and number of leukocytes of the soybeen oil group, the rape seed oil group, and the red pepper oil group were significantly lower than the sesame oil group(P<0.01).

Backgrounds and Objectives: Vascular dementia is a group of dementing disoders arising from various stroke syndrome. Among these. subcortical ischemic vascular dementia (SIVD) is regarded as a relatively distinct clinical entity. However, MRI patterns of SIVD are not homogenous. In some patients, lacunes are dominant, and in others, subcortical white matter changes are. This study was designed to compare risk factor profiles between SIVD with and without multiple lacunes. Methods: We divided 47 subjects (22 males, mean age. 68 years) recruited from VADAPET (Multicenter Trial For Evaluation Of The Changes In the PET Images Of Subcortical Vascular Dementia Patient) study into two groups one with more than 5 lacunes in deep gray matter (lacune group) and the other with 5 or less(non-lacune group) Clinical characteristics and laboratory findings of two groups were compared. Results: Nineteen of 47 patients (40%) belonged to the lacune group. The lacune and non-lacune groups d d not differ in the following variables: age, hypertension, diabetes mellitus, hyperlipidemia heart disease, history of stroke or TIA, history of trauma or major surgery, family history of hypertension stroke, or dementia, age at diagnosis of dementia, body mass index, white blood cell count, ESR, CRP, fibrinogen, hemoglobin A1C, total cholesterol. LDL cholesterol creatinine, proteinuria, glucosuria, and microhematuria. However, male sex, smoking alcohol. hemoglobin, and HDL cholesterol were possibly associated more with lacune group SIVD than with non-lacune group (p<0 1) Multivariate analyses revealed that smoking, hemoglobin, and HDL cholesterol were independent predictors of SIVD with multiple lacunes Conclusion: Our study suggests that SIVD with multiple lacunes may be significantly different in smoking habits hemoglobin, and HDL cholesterol from SIVD without multiple lacunes.

In this paper, an optical connection method for the application of subscriber loop and for the realization of FTTH(fiber to the home)is developed. Loss values of possible factors affecting connection loss are evaluated. Practical experimental values are measured for the case of factors. For connection of optical fiber, V-groove is fabricated with different widths and four types by photo-lithography method. Connection loss and refraction loss are measured by alignment to optical fiber on fabricated V-groove. It's compared with measurements by using index matching oil. With the result that measured average connection loss of 0.12dB. and average refraction loss of -45dB expected to application of subscriber optical cable loop. By designed and fabricated with different widths, this connection method can aligned and fixed optical fibers at the same time and compensated to loss values of possible factors.

The dynamic model of the suspension system is developed by using both sky-hook control and output feedback control techniques, based on the performance sensitivity index. Many vehicles use sky-hook control theory operated with only one sensor, due to relatively low cost and easy implementation. On the other hand, output feedback control implemented with state variables has difficulties in measuring such as tire deflection, etc.

The purpose of this study was to evaluate the effects of diet condition and caffeine ingestion prior to long distance treadmill running on the GLUT-4 protein expression in Sprague-Dawley rats' soleus muscle. Total is rats were used For subjects and assigned to six groups: Fasting control(FaC group), feeding control(FeC), asting+exercise(FaE), feeding +exercise(FeE), Fasting +caffeine+exercise(FaCE), and Feeding+caffeine+exercise(FeCE). Each animal belongs to fasting group was forced to be in fasting state at least for 14 hours, The food was provided to each rat in feeding group 12minutes prior to treadmill running and the caffeine was ingested through the stainless steel tube 60minutes prior to exercise. All rats in exercise groups were forced to perform treadmill running for B9 minutes at the speed of 18m/min, and 0%grade, immediately after exercise, all animal was anesthetized by Chlorofolm (DC Chemical, Co, Ltd) and about 10ml of blood was drawn from each animal's heart and than soleus muscle was exposed and separated from the rat's leg. we found that the GLUT-4 in feeding groups increased much significantly compared to fasting groups(p<.05). The exercise in fasting state appeared to suppress the expression of GLUT-4 protein different from the exercise in feeding state. Cafreine ingestion prior to treadmill running of 60 minutes induced the significant increase or GLUT-4 protein expression both in fasting or feeding states.

본 연구는 라디에타소나무 제재목의 균 변색을 제거하기 위한 표백처리의 사용 가능성을 조사하기 위하여 수행하였다. 염소계 표백제인 아염소산나트륨과 차아염소산나트륨은 표백조건(약제농도, 처리온도, 처리시간)의 조절에 따라 만족할만한 변색제거 효과를 얻을 수 있었다. 비염소계 표백제인 과산화수소는 표백조건의 조절만으로는 변색제거가 불가능하였으나 규산나트륨과 수산화나트륨을 활성제로 첨가하는 경우에는 염소계 표백제보다 탁월한 변색제거 효과를 나타내었다. 그러나 활성제 첨가에 따라 재색의 녹색화 문제가 발생하였는데, 앞으로 이러한 문제점을 해결하기 위한 연구가 진행되어야 할 것이다. 또한, 앞으로 본 연구를 통해 개발된 변색제거방법의 현장 적용을 후속 연구도 필요하다고 본다. The feasibility of using bleaching treatments for removing fungal stain was evaluated on heavily stained raiadta pine sapwood. Sodium chlorite and sodium hypochlorite appeared to destain fungal discoloration by providing proper treatment conditions (chemical concentration, treatment temperature, and treatment time), while hydrogen peroxide did not remove fungal stain under the bleaching regimes evaluated. The addition of sodium silicate and sodium hydroxide in the hydrogen peroxide solution as a buffer could remove fungal discoloration completely:; however, the color of wood surface turned faint green after bleaching, thereby reducing the lightness of bleached samples. The results suggest that hydrogen peroxide bleaching could be a feasible method for removing fungal discoloration of stained radiata pine sapwood, although further research is needed to solve the problem of color change after bleaching Also, further tests under field conditions are recommended.
