노정관,윤석규 진주산업대학교 1999 산업과학기술연구소보 Vol.- No.6

아까시나무재의 色相과 强度的 性能등의 材質을 고려한 새로운 用途로서 2종류의 온돌용마루판 제조와 그 성능늘 검토하였다. 1.合成樹脂 複合 아까시나무 溫突用 마루板 0.5㎜ 아까시나무 單板과 ABS(아크릴로니트릴-부타디엔-스틸렌)樹脂를 이용하여 10x10㎝의 아까시나무 溫突用 마루板을 射出成形하여 製造하였다. 본 제품의 熱傳達速度는 市販의 溫突用 마루板 에비해 비교적 양호하였으며, 熱變形溫度는 160℃로 온돌 위에 시공하여 이용하여도 열에 의한 문제는 없을 것으로 생각된다. 또한, 휨강도도 아까시나무 素材와 거의 유사하였으며, 市販의 온돌용 마루판에 비해서는 우수하였다. 合成樹脂와 아까시나무 單板間의 耐水接着性能은 1시간 끓임과 60℃, 20時間乾燥 후에도 剝籬되지 않았다. 2.폐비닐 複合 아까시나무 溫突用 마루板 폐비닐, 탈크 및 목분을 組合하여 製造한 시트상의 基材에 0.5㎜ 아까시나무 單板을 積層接着하여 製造하였다.두께가 3.2㎜로 기존의 제품에 비해 얇기 때문에 熱傳達 性能이 우수하고, 再生樹脂板體와 아까시나무 單板間의 耐水 接着性能 및 耐熱性도 비교적 良好하였다. This research was endeavored to manufacture two kinds of Ondol floor made of Black Locust with consideration of color and strength, and the bonding properties were evaluated. 1.Composite Ondol floor with locust veneer and synthetic resin The Ondol floor (10 by 10㎝) was manufactured by injection moulding with locust veneer (thickness 0.5㎜) and ABS (acrylonitry-butadiene-styrene) resin. The heat transfer rate and bending strength of manufactured Ondol floor were comparatively higher than those of current commercial products, and the bending strength was even similar with locust lumber, In aspect of the water resistance(wet bonding property) between synthetic resin and locust veneer, the delamination was not occurred after 20 hours drying at 60℃ with 1 hour boiling. 2.Composite Ondol floor with locust veneer and recycled vinyl The Ondol floor was manufactured by laminating locust veneer (thickness 0.5㎜) with base plate on sheet containing recycled vinyl, talc and sawdust. Compared with current commercial products, the heat transfer property was superior due to slim thickness (3.2㎜). In addition, the heat resistance and water resistance between recycled resin plate and locust veneer were also suitable.

본 연구는 이익관리에 대한 증거와 그 증거가 회계연구자들에 대한 함의를 검토하고 이익관리에 대한 가능한 미래연구 분야를 개관한다. 전반적으로, 대부분의 선행연구들은 이익관리가 존재하는지의 여부와 이익관리가 행해지는 이유에 대해서만 초점을 맞추고 있다. 선행연구의 결과는 이익관리가 주식시장의 인지에 영향을 미치기 위하여, 경영자의 보상을 증가시키기 위하여, 차입계약의 위반가능성을 감소시키기 위하여, 그리고 규제적 개입을 회피하기 위한 목적 등을 포함한 다양한 동기에서 수행되고 있다는 것을 시사해 준다. 본 연구의 검토결과가 갖는 한가지 함의는 이익관리의 존재여부에 대한 보다 강력한 검정으로부터 얻어질 가능성은 적은 반면, 회계상의 재량이 이익관리에 얼마나 빈번하게 사용되는지 그리고 이러한 행위가 이익에 얼마나 많은 영향을 미치는지에 대한 연구에서 미래의 공헌점이 얻어질 것으로 생각된다. 또한, 경제에서 이익관리가 주가와 자원배분에 미치는 영향에 대한 상반된 결과를 더욱 일치시키는 것이 필요할 것으로 생각된다.

호알칼리성 Bacillus sp.F204와 Bacillus sp.K17의 원형질체 융합

성낙계,노종수,박석규,정영철 순천대학교 기초과학연구소 1990 基礎科學硏究誌 Vol.1 No.-

To develop cellulase and xylanase-producing strain by protoplast fusion, alkalophilic Bacillus sp. F204 and K17 were treated with NTG(N-methyl-N'-nitro-N-nitrosoguanidine) and isolated antibiotics resistant strains of S20 (Km', Cm') and G70(Str'). The frequency of protoplast formation was about 95% when cells of mid-log phase were treated with 200㎍/㎖ lysozyme at 37℃ for 30-45 minutes. Under addition of 0.4-0.5M sodium succinate, 0.5% casamino acid, 1.5% polyvinylpyrrolidone, 25mM MgCl_2 and 50mM CaCl_2 to the regeneration medium, the regeneration frequency of Bacillus sp. F204 and K17 was 24.9% and 26.2%, respectively. the fusion frequency was 6.6×10^-6 in the presence of 30% polyethylene glycol 6000 containing 50mM Ca^++ at 45℃ for 5 minutes. Cellulase complex and xylanase activities of fusant were compared with parental strains.

본 논문에서는 GMDH(Group Method of Data Handling) 알고리즘을 이용하여 퍼지 모델의 구조와 파라미터를 설정하는 알고리즘을 제안하였다. 퍼지 함의 규칙의 전건부 구조와 파라미터를 동정하기 위해 GMDH 알고리즘과 퍼지 추론을 사용하였고 최적의 후건부 파라미터를 동정하기 위해 최소 자승법을 사용하였다. 제안된 모델링 방법의 성능을 평가하기 위해서 가스로 시계열 데이터와 하수처리 데이터를 사용하였다. 제안된 방법을 사용하면 다른 모델에 비해 우수한 성능을 가진 지능 모델을 얻을수 있다. The Proposed fuzzy modeling implements system structure and parameter identification using the GMDH(Group Method of Data Handling) Algorithm. In this method, We use the GMDH algorithm and fuzzy inference to identify the premise structure and parameter of fuzzy implication rules and least square method to identify optimum consequence parameter. Time seris data for gas furnace and wastewatertreatment data are used for purpose of evaluating the performance of the proposed fuzzy.

The diagnostic requirements were suggested and explained regarding the systems of differentiation of symptoms and signs in the third year study of standardization and unification of the terms and conditions used for diagnosis in oriental medicine. The systems were as follows : - analyzing and differentiating of epidemic febrile disease - analyzing and differentiating in accordance with the Sasang constitution medicine based on four-type recognition - differentiation of disease according to pathological changes of Chong and Ren channels - standards for diagnosis of women's disease - standards for diagnosis of children's disease - standards for diagnosis of motor and sensor disturbance (-muscle. born, joint, etc.) - standards for diagnosis of neuropsychiatric disease - standards for diagnosis of five sense organ disease - standards for diagnosis of external disease The indivisual diagnosis pattern was arranged by the diagnostic requirements in the following order : another name, notion of diagnosis pattern, index of differentiation of symptoms and signs, the main point of diagnosis, analysis of diagnosis pattern, discrimination of diagnosis pattern, prognosis, a way of curing a disease, prescription, herbs in common use, disease appearing the diagnosis pattern, documents. The standards for diagnosis of each disease was arranged by the diagnostic requirements in the following order : another name, notion of disease, the main point of diagnosis, analyzing and differentiating of disease, analysis of disease, discrimination of disease, prognosis, a way of curing and prescription of disease, disease in western medicine appearing the disease in oriental medicine, documents.

Polynomial Fuzzy Radial Basis Function Neural Network Classifiers Realized with the Aid of Boundary Area Decision

Seok-Beom Roh,Sung-Kwun Oh 대한전기학회 2014 Journal of Electrical Engineering & Technology Vol.9 No.6

In the area of clustering, there are numerous approaches to construct clusters in the input space. For regression problem, when forming clusters being a part of the overall model, the relationships between the input space and the output space are essential and have to be taken into consideration. Conditional Fuzzy C-Means (c-FCM) clustering offers an opportunity to analyze the structure in the input space with the mechanism of supervision implied by the distribution of data present in the output space. However, like other clustering methods, c-FCM focuses on the distribution of the data. In this paper, we introduce a new method, which by making use of the ambiguity index focuses on the boundaries of the clusters whose determination is essential to the quality of the ensuing classification procedures. The introduced design is illustrated with the aid of numeric examples that provide a detailed insight into the performance of the fuzzy classifiers and quantify several essentials design aspects.
