Purpose: The consequences of precipitously rising allergic skin inflammation rates worldwide have accelerated the risk of atopic dermatitis (AD). Natural product-based agents with good efficacy and low risk of side effects offer promising prevention and treatment strategies for inflammation-related diseases. We have already reported that Platycodon grandiflorum root-derived saponins (Changkil saponins, CKS) have many pharmacological effects, including anti-inflammatory and anti-allergic effects, but its influence on AD remains unclear. Therefore, we evaluated the inhibitory effect of CKS, mainly platycodin D, on AD-like skin symptoms in mice and the possible mechanisms in cells. Methods: Mice were sensitized and challenged with 2,4-dinitrochlorobenzene (DNCB). Four weeks after challenge, mice were treated with oral administration of CKS for 4 weeks. In addition, cells were used to evaluate the effect of CKS, mainly platycodin D, on the TARC expression regulated mechanism. Results: CKS attenuated DNCB-induced dermatitis severity, serum levels of IgE and TARC, and mRNA expression of TARC, TNF-α, IFN-γ, IL-4, IL-5, and IL-13 in mice. Histopathological examination showed reduced thickness of the epidermis/dermis and dermal infiltration of inflammatory cells and mast cells in the ears. Moreover, CKS and platycodin D inhibited TNF-α/IFN-γ-induced TARC expression through the suppression of NF-κB and STAT1 and induction of Nrf2/ARE-mediated hemeoxygenase-1 (HO-1) expression in cells. Conclusion: We suggest that CKS and platycodin D inhibited the development of AD-like skin symptoms by regulating cytokine mediators and may be an effective alternative therapy for AD-like skin symptoms.ⓒ2014 Elsevler Gmbh.

Background : To compare of the clinical and radiologic results between microscopic decompression(MD) and MD with Device for Intervertebral Assisted Motion(DIAM) in lumbar canal stenosis. Materials and Methods : The retrospective evaluation was performed after surgery of stenosis. MD with DIAM was performed in 17 cases(Group A) and MD in 20 cases(Group B). In radiologic evaluation, checked the preoperative and postoperative disc height, intervertebral foraminal dimension, lumbar lordotic angle and instability by Panjabi. In clinical evaluation, preoperative and postoperative pain was checked by VAS. Disability was checked by RMQ(Roland Morris Questionnaire) and sf-36(PF). Results : In radiologic results, disc height changed from 11mm to 13mm in Group A(11mm to 11.8mm in Group B)(p=0.669). Intervertebral foraminal dimension was changed from 20.6mm to 22.3mm in Group A(19.5mm to 20.5mm in Group B)(p=0.536). Lumbar lordotic angle was changed from 15.40 to 14.20 in Group A(14.80 to 19.50 in Group B)(p=0.033). Instability score was improved from 0.9 to 0.2 in Group A(1 to 0.2 in Group B)(p=0.642). VAS score improved in group A from 10 to 2(9 to 2 in Group B)(p=0.612). On sf-36(PF), the values changed from 34/100 to 58/100 in Group A(30/100 to 58/100 in Group B)(p=0.535). Conclusion : Using dynamic interspinous stabilizer(DIAM) appears to be a useful and effective methods in surgery of lumbar canal stenosis with better radiologic results than MD only, but lumbar lordotic angle was decreased, slightly

紅蔘褐變의 適合한 促進方法을 究明하기 위하여 人蔘에 糖, amino酸 및 無機窒素化合物을 處理한 結果 糖類中에서는 maltose와 glucose가 가장 强한 褐變促進作用을 나타내었다. amino酸은 basic amino acid인 lysine, histidine, arginine이 가장 크게 促進했으며 糖과 amino酸 混合處理에서는 glucose와 glutamic acid 退合處理區가 가장 크게 促進되었다. Glucose 濃度別 處理時의 褐變促進效果는 glucose濃度가 增加함에 따라 褐變이 促進되었으며 無機窒素化合物中에서는 urea>(NH₄)₂)HCO₃>COONH₄등의 順으로 褐變이 促進되었다. In order to find out pertinent methods for the acceleration of browing during ginseng processing, various treatments were made or fresh ginseng (Panax Ginseng C.A. Meyer) with sugars, amino acids and inorganic nitrogenous compounds and the extent of browning was measured. Among sugars tested, maltose resulted in the greatest acceleration of browning followed in decreasing order by glucose and lactose, whereas pentoses, fructose, sucrose and raffinose had negligible effect. A marked browning occurred in ginseng treated with basic amino acids, while the extent of browning was not greatly increased when ginseng was treated with aliphatic amino acids, hydroxy amino acids, or acidic amino acids used in the experiment. Among treatments with sugar-amino acid mixture, a mixture of glucose with glutamic acid gave the greatest acceleration. The brown color intensity gradually increased with an increase in glucose concentration for up to 0.5M. inorganic nitrogenous compounds enhanced the browning in general, and the effect varied greatly with the different compounds.

Dual-Slope型 A/D 變換方式의 速度改善

金道鉉,申宰浩 명지대학교 1983 明大論文集 Vol.14 No.-

Dual-Slope型 A/D轉換方式은 線型性 및 分解度외의 여러면에서 많은 長點을 갖고 있지만, 變換速度가 늦다는 큰 短點을 갖고 있다. 本 論文에서는 技術的인 면에서 轉換速度의 增加 또는 標本速度의 增加를 實現할 수 있는 점을 提示하고 分析한다. Though the dual-slope type A/D conversion method has many advantages: such as good differential-linearity, excellent linearity, easy to autozero, wide dynamic range & resolution independent of many component variations and independent of clock rate, this method has the serious disadvantage which is slow conversion speed. On the view of technology, this paper shows and analyzes the point which is the increment of conversion speed or sampling rate.

We discuss that the proliferation of new types of retailers such as Internet shopping mails, home shopping systems, which use telecommunication media as means of providing information of products, makes delivery service generally available. Then, we show that the delivery service can be used strategically for profit maximization by intentionally homogenizing consumers and, furthermore, social welfare generally increases by this delivery service unless the cost of delivery service is higher than that of ail consumer groups.

시나리오 역할 게임을 통한 신속 시스템 설계/검증 방법 : 패키지 응용 시스템을 대상으로 for Package Based System Implementation

예도경,이용재,강두호,최열현 한국경영과학회 1998 한국경영과학회 학술대회논문집 Vol.- No.1

Recently, many enterprises wish to preoccupy competitive positions in the market by motivating themselves towards CALS(Commerce At Light Speed), and try hard to achieve system implementation with the use of new concept-based backbone systems such as ERP(Enterprise Resource Planning) or ERP(Enterprise Resource Planning). However, unfortunately there is an inevitable discrepancy during implementation period between package vendors and customers due to lack of clear methodology and misunderstanding about system. In some cases, consensus on partially verified system design invokes customers’ continuous change demands and often it tends to result in unnecessary project delays. PDM application system implementation project of the company L has been studied here to solve these sorts of problems. The major yields of this work are achievement of a willing approval from customers and rapid system design under a time-limited and conceptually defined project scope, and finally, through fully verified system design, we were able to reach successful system implementation.

Charged particles create their tracks in most dielectric solids. These tracks can be viewed under optical microscope after proper chemical etching. Tracks of uranium fission fragments in obsidians also can be viewed after etching by HF solution and used for age dating. In this paper, dating formular and experimental procedures for fission track dating are introduced. And spontaneous and induced fission tracks by thermal neutrons are counted under optical microscope (magnification of 400x). Measured fission track ages of obsidian samples, OM No. 147 and HM No. 40 are 8.86 × 10 exp(5)y and 7.67 × 10 exp(5)y, respectively.

本 試驗은 1985年 3월 부터 1986年 3月에 걸쳐 栽植樣式이 生育과 收量에 미치는 影響을 究明하기 위하여 濟州大學校 亞熱帶農業硏究所 plastic film house에서 遂行되었다. 그 結果를 要約하면 다음과 같다. 바나나의 草長, 葉數, 葉幅, 葉長, 果掌數, 果房重은 栽植樣式에 따라 影響을 받지 않았으나 假莖長, 假莖直徑, 抽穗期, 成熟期는 有意性이 인정되어 正方形, 三角形, 長方形, 栽植樣式 順으로 假莖長과 假莖直徑이 增加하였고 抽穗期와 成熟期도 短縮되었다. 果掌當 果指數와 果掌重은 栽植樣式에 따라 1段에서 差異가 있었고 長方形, 三角形 栽植樣式에서 2段에서는 현저하게 감소하였으나 3段 이후부터는 緩慢하게 감소되는 傾向을 나타내었다. 果掌當 果指長과 果指直徑은 1段에 比해 2段에서 增加하였는데 長方形, 正方形, 栽植樣式에서 1段∼2段 差가 컸으며 果指直徑의 變化는 栽植樣式 및 果掌間에 따라서 差異가 크게 나타났다. 正方形, 三角形 栽植樣式에서 1段에 比해 2段 果指重이 增加하였으나 3段 이후부터는 감소되는 경향을 나타내고 栽植樣式 및 果掌間에 따라 差異가 컸다. This experiment was carried out to elucidate the influence of spatial arrangement at planting on the growth and yield in bananas (Musa cavendish Lambert 'Dwarf Cavendish') from March, 1985 to March, 1986 in the plastic film house at Research Institute for Subtropical Agriculture, Cheju National University, Cheju, Korea. The results obtained are summarized as follows. Plant height, no. of leaves, leaf width, leaf length, no. of hands, and bunch weight, were little affected by planting pattern. However, pseudostem length and diameter were greater and date of emergence and maturity were earlier in the order of regular, triangular, rectangular planting. The number of fingers/hand and hand weight were significantly affected by planting pattern in 1st hands and decreased remarkably in 2nd hand of the rectangular and triangular planting, but tended to be decreased slowly from 3rd hand. Finger length and diameter/hand were greater in 2nd hand than in 1st hand and more significant in the difference of 1-2 hands in rectangular and regular planting than that of triangular planting, finger diameter/hand were afected remarkably by planting pattern or hands. Finger weight/hand were increased in 2nd hand against 1st at regular and triangular planting, but tended to be decreased from 3rd hand and affected by planting pattern or hands.
