적응알고리듬의 VLSI 구현에 있어서 파이프라이닝이나 시스토릭과 같은 구조적 설계기법을 이용하여 알고리듬을 변환하는 것은 효과적이다. 알고리듬 변환은 z-변환 영역에서 연산의 규칙성과 반복성을 찾아 이루어 진다. 본 논문에서는 이차원 필터와 계수갱신 시스템을 시스토릭 구조로 설계하여 LMS의 확장 형태인 TDLMS을 STDLMS로 변환한다. 변화된 STDLMS를 이용 이차원 ALE를 Altera사의 Max-PlusII 상에서 구현하여 시뮬레이션을 통해 성능을 평가한다. 시뮬레이션 결과 salt-pepper 잡음과 가우시안 잡음에 오염된 화상을 ALE가 개선할 수 있음을 보였다. In VLSI realization of adaptive algorithm. it is necessary and efficient that the algorithm is transformed to structural one suitably using architectural design techniques such as pipelining or systolic array. These transform method use regular and recursive of operation of the algorithm on z-transform domain. In this paper, the TDLMS which is a extended version of LMS is transformed to STDLMS which has systolic array architecture in two dimensional filter and coefficients update system. The transformed STDLMS is applied for realization of two dimensional ALE. And the ALE performances are evaluated by Max-PlusII of Altera Co.. The simulation results show that the ALE enhances image data which were corrupted by salt-pepper noise and Gaussian noise.

노완섭 서울保健大學 1983 論文集 Vol.3 No.1

한국산 고려인삼 및 인삼제품의 안전성을 검토하기 위하여 곰팡이를 순수분리하고 이들 곰팡이에 대한 aflatoxin생성여부를 확인한 결과는 다음과 같다. 1) 인삼 및 인산제품 6종으로 부터 곰팡이를 순수분리하고 이들 곰팡이에 대한 aflatoxin 생성여부를 확인하였다. 2) 분리된 곰팡이의 수는 수삼에서 10개, 건삼에서 7개, 당삼 및 인삼분말에서 각각 2개, 홍삼 및 인삼차에서는 1개씩 분리되었다. 3) 분리된 곰팡이 중에서 aflatoxin 생성가능성이 인정되는 것은 수삼에서 2개, 건삼에서 1개 뿐이었다. 4) 검출된 aflatoxin의 종류는 B_(1), 및 B_(2) 였으며 생성량은 배양액 Kg당 1~2ng 정도이고, 인삼제품에서는 aflatoxin 생성이 전혀 없었다. 5) Aflatoxin 생성 가능성이 인정되는 곰팡이는 Aspergillus flavus, Aspergillus parasiticus 및 Penicillium puberulum으로 동정하였다. In order to survey the distribution of molds in Korean Ginseng and its products, molds were isolated from their samples to obtain 23 strains. Among them, 3 strains were found to produce aflatoxins and identified as Aspergillus flavus, Aspergillus parasiticus and Penicillium puberulum. The type of aflatoxin produced was identified as B_(1), B_(2) and G_(1).

The purpose of this study is to clarify the effect of the monomer ratio on properties of the polymer-modified mortars using methyl methacrylate-ethyl acrylate latexes, and to obtain basic data necessary to develop appropriate latexes for cement modifiers. This paper deals with the effect of the monomer ratio on the typical properties of polymer-modified mortars with methyl methacrylate-ethyl acrylate latexes. The polymer-modified mortars using MMA/EA latexes are prepared with various polymer-cement ratio, and tested for strengths, water absorption, and chloride-ion penetration depth. The test results indicate that the monomer ratio is very important factors to characterize the strength properties of polymer-modified mortars, but the water absorption and chloride-ion penetration depth are influenced by polymer-cement ratio rather than monomer ratios.

The purpose of this research is make out construction specifications for International Construction. Using off-shore products incur cost increase and longer delivery term of construction. and inconvenient on International Construction. Expand the range of additional local products conforming to performance. Life Cycle Cost. maintainability. operability. user's acceptability, etc.. And this study is suggest the standard formats and the techniques for construction specification.

The setting shrinkage behavior in polyester mortars with two-phase shrinkage reducing agent(SRA) was observed at the ambient temperature. Polyester mortars were prepared with various styrene contents and two-phase shrinkage reducing agent(SRA) contents. The length change and exotherm temperature of polyester mortars were continuously monitored by a noncontact-type automatic length change measuring apparatus and a thermocouple embedded respectively. Low-shrinkage or non-shrinkage of polyester mortars should be accomplished by adjusting styrene content and SRA content.

The primary objective of this study was tested the baking properties of Korean wheat. In test results, the wheat which was harvested from all over the Korea, not suitable for making bread and cake products. However, some of possibilities to make bread were found by using vital gluten as well as additives. Out of Korean wheat classes, the Tapdong wheat showed good properties for bread making, and it is recommended to develope it as bread making wheat by segregating from other classes in seeding and harvesting.

우리 나라 상장기업의 법인세평준화성향에 대한 실증 연구

정문현,김완섭 釜山大學校 商科大學 1998 釜山商大論集 Vol.69 No.-

The purpose of this paper is to examine whether firms use the indirect tax reduction and exemption (reserve and special depreciation) to smooth corporate income tax. The corporate income tax is not determined strictly by gross profits itself but taxable profits which are able to be legally adjusted by deductible items. Therefore, the firms would like to minimize their own corporate income tax within tax reduction and exemption control law. It is not the final goal for firms to minimize the tax burden because a remarkable decrease of corporate income tax brings audit of tax auditorily. To reduce the risk of tax audit is more important for firms in the long-term. In order to avoid the tax audit, the firms' decision making about corporate income tax would not minimize tax but smooth tax. In some cases, tax smoothing leads to lighter of tax burden in the long-term than tax burden minimization in the short-term. Tax smoothing means to stabilize tax burden for a firm at a certain level. Established hypothesis in order to practice this study is as follows : The firms smooth the corporate income tax using indirect tax reduction and exemption. Wilcoxon matched-pairs signed ranks test is used to test hypothesis. The results of this study indicate that firms use the reserve and special depreciation to smooth corporate income tax. This study examined that tax smoothing tendency is measured by the reserve and special depreciation amounts without identifying corporate managers' intention to set reserve and special depreciation. But the implications of these results suggest that new recognition is offered to information users for corporate income tax reported accounting entity and the problems of tax authorities' operations.

당류, Cysteine, pH 및 저장온도가 Acerola 과즙음료 중의 비타민 C의 안정도에 미치는 영향

박종범,노완섭 동국대학교 산업기술연구원 1999 산업기술논문집 Vol.14 No.-

당류, Cysteine, pH 및 저장온도가 acerola 과즙음료 중의 비타민 C의 안정도에 미치는 영향을 조사하였다. Acerola 과즙음료 중의 비타민 C의 안정도는 40℃ 저장 8주후, 당류의 종류와 cysteine 첨가 여부 및 pH에 영향을 받았다. 비타민 C의 안정도는 과당, 설탕, 포도당, sorbitol 순으로 효과가 있었으며, pH 3.0에서 최대효과를 pH 4.0에서 최저효과를 나타내었으며, cysteine을 첨가한 경우가 효과적이었으며, 저장온도가 증가함에 따라 비타민 C의 파괴속도는 증가하였다. The acerola juice was stored at 40℃ for 8 weeks to study the influence of sweeteners, cysteine and pH on the stability of vitamin C. The potency of vitamin C in this study decreased rapidly during an initial period for about first 2 weeks. Among the four different sweetened juices, retention of vitamin C was in high order as follows fructose, sucrose, glucose and sorbitol. Retention of vitamin C was shown to change with pH and was the least stable at pH 4.0. In addition to the optimum pH for the stability was found to be pH 3.0.
