약포의 첨가당과 건조방법이 육포의 품질과 저장성에 미치는 영향을 알아보기 위하여 저장상, 기계적 특성과 관능검사를 실시하였다 육포의 저장 기간 중에 수분활성 도는 경시적으로 감소경향을 나타내었고 저장 5주에는 꿀과 조청을 첨가한 천연건조시료(N-H, N-R)가 모두 0.71로 가장 낮은 값을 보였다. 모든 시료의 pH는 저장에 따라 감소하였으며 꿀을 첨가하여 열풍 건조한 육포(H-H)가 5.22로 가장 낮았다. 색도의 L, a, b값은 저장기간 중에 모두 감소 경향을 보였다. 저장기간 중 모든 시료에 있어서 TBA값이 증가하는 것으로 나타났고, 설탕시립첨가육포(N-S, H-S, S-S)는 건조방법과 관계없이 가장 낮은 값을 보였으며 꿀첨가육포(N-H, H-H, S-H)가 가장 높았다. 모든 시료의 총미생물수와 젖산균수는 저장 기간이 경과함에 따라 증가하였으며, 저장 5주시 설탕시럽첨가 열풍건조한 육포(H-S)가 가장 낮았다. 모든 시료의 기계적 조직특성은 저장기간이 경과함에 따라 증가하였다. 탄력성과 응집성은 대체로 꿀첨가시료가 가장 높았고 씹힘성과 점착성·견고성은 설탕시럽첨가 천연건조 시료가 가장 높게 나타났다. 천연건조시료는 포장방법에 관계없이 거의 모든 항목에 걸쳐 저장기간이 경과함에 따라 관능점수가 감소하였고, 열풍건조시료들의 관능점수는 포장방법에 관계없이 천연건조시료들에 비해 현저히 높은 점수를 나타내었다.

The rotary feed axes of a 5-axis machine tool can increase the freedom of the tool posture, while reducing feed speed and rigidity. In addition, as a ball-end mill is inevitably used during machining by rotational feed, the step-over length is reduced compared to the flat-end mill, thereby reducing the material removal rate. Therefore, this study attempts to improve the material removal rate, feed speed, and machining stability using the corner radius flat-end mill and a fixed controlled machining method for the rotary feed axes during roughing. In addition, the tapered ball-end mill and simultaneously controlled machining method for the rotary feed axes were used for finishing to improve the propeller's 5-axis machining efficiency by enhancing the surface quality. In order to create the tool path effectively and easily, we propose a specific approach for using the propeller's geometric properties and evaluate the effectiveness of the proposed method by comparing it with the method of the dedicated module.

대중교통 정보 시스템의 고도화와 정보 신뢰도 유지를 위해서는 대중 교통수단 노선과 운행 정보에 대한 정확도 향상은 매우 중요한 사안이다. 이러한 위치기반체계에 대한 정확도를 측정하기 위해 GPS를 활용한 매우 다양한 방법들이 존재하고 있지만 버스 노선 등과 같이 이동 차량에 탑재된 GPS를 통해 결정된 선형 객체의 동적인 위치 정확도를 평가하는 연구는 아직 미비하다. 이에 본 연구의 목적은 단일 버퍼링 기법을 이용하여 GPS에 의해 실시간 측정된 버스 노선의 정확도 평가 방안을 제시하는 것이다. 이를 위해 경기도 안양시 일대의 정류소와 버스 노선을 대상으로 단독 측위, DGPS, GPS/INS 에 따른 정적 및 동적 측위 결과를 상호 비교하고 정확도와 오차의 영향을 분석하였다. 연구 결과로서 정류소 위치에 대한 단독측위의 경우 실시간 DGPS 관측과 GPS/INS DGPS 관측과 비교하여 2개의 관측성과 모두 5m 이내 정확도 범위 내에 결과를 얻을 수 있었다. 특히, 노선의 경우 공공측량 작업 규정 세부기준의 축척별 위치 정확도에 근거하여 단독측위 14.5m의 오차는 1:20,000, 18.1m의 오차는 1:25,000 축척의 오차범위 정확도를 가지며, DGPS의 16.9m와 18.5m의 오차는 1:25,000 축척의 오차범위, GPS/INS의 18.4m와 18.5m의 오차는 1;25,000 축척의 오차 범위로 정확도를 평가할 수 있었다. 본 연구에서 제시한 방법은 버스 기반 정보 구축을 위한 GPS 현장 조사 시 동적 위치 측정 방법론의 타당성 검토와 높은 정밀도의 노선 위치 정보 구축에 활용 가능할 것이다.

본 논문에서는 Habermann의 deadlock 회피책에 대한 기존의 방안을 향상시킬 수 있는 방법을 고안하였다. 먼저 correction, efficiency, concurrency 측면에서 기존의 개선 방법들을 비교 분석한 다음, 대표적인 Kameda의 개선방안을 심도있게 논의한다. Dinic의 알고리듬을 채택한 Kamedia의 방법에서는 실행시간 O($mn^1.5$)이 요구되지만 Karzanov의 wave method를 응용하여 본고에서 제안한 faster algorithm에서는 실행시간 O($mn^1.5$)이 됨을 보인다.

The diagnosis of canine diabetes mellitus is generally made by measuring serum fructosamine levels. The Rosental's end points Tas and El Din's kinetic, and Johnson and colleagues'kinetic techiniques were compared for the measuring serum fructosamine levels. In the Rosental's end point methods within-run and between-run coefficient of variability (CV) were 2.4-3.5% and 6.8-8.5%, respectively, and in the Tas and El Din's kinetic method, within-run and between-run CV were 1.3-3.0% and 3.4-3.9%, respectively. In the Johnson and colleagues'kinetic methods within-run and between-run CV were 0-1.8% and 3.1-6.8%1 ruts- pectively. Hyperlipidemia induced by oral administration of 3 ml of corn oil per kilogram body weight did not affect serum fructosamine concentration significantly in the Johnson and colleagues' kinetic method Johnson and colleagues'kinetic method is most reliable and consistant on the basis of comparison study.

The purpose of this study is to provide basic data to assist students and industrial designers in fashion by examining the trend of designing women's wear with the SCAMPER method. In the research, the seven types of SCAMPER methods for fashion design were classified based on the previous studies. From 2010 S/S to 2020 S/S, data from 5,149 photographs were collected through overlapping checks and classified by SCAMPER method type. Data analysis was performed using SPSS 25.0 for frequency analysis. As a result, in the SCAMPER "combine" method, more than two items were combined, or structural details were combined with items. In the most applied "adapt" method was involved imitating similar images, or natural forms, or other objects. The "modify" method was applied by changing the shape of some details in basic fashion items. The "magnify" method was applied by enlarging, elongating, or elevating some details of fashion items. The "minify" method was applied by minimizing, shortening, or lowering some details of basic fashion. The method of "put to other use" was expressed throughout the clothing by using non-fabric or trimmings such as metal, beads, and strings. The "rearrange" method was applied by repositioning the top and bottom, front and back, or outside and inside in fashion items and in details. The "reverse" method was applied by reversing the style of fashion, mix-and-match fabric, or switching the gender of the fashion items.

The consumption of sugar in our diet increased so great that much U. S. dollars are spended to import sugar source from foreign contries. To replace a part of it we adopted mother plant and seeds of the well-known Stevia (Stevia rebaudiana Bertoni M.) originated from south America, from the Agricultural Experimental Station of Hokkaido, Japan, in 1974. In order to determine the growth condition of Stevia in our climate and soil condition, the results of survey and determination were as follows: 1. Germination rate of Stevia was averaged 33.6% at 35 th day after seedling and the maximum germination period was between 5 and 20 days after seedling. 2. The seedling rate of Stevia was about 8%. 3. Establishment of roots of Stevia propagated by cutting method was above 90% but only S-1 strain showed lower rate., 75%. 4. S-2 strain showed the best growth rate that was about 160cm by plant height and it was decreased by the following order : S-4, S-3, S-1, S-6 and S-5 strains. 5. S-4 strain resulted in 45 branches that was the highest number among strains tested and S-2 strain was the next. 6. The content of sweetening compound of Stevia, stevioside, was 5.3% in S-1, S-2, S-5 and S-4 strains but S-3 and $S^*$-6 strains were relatively low content, 4.9%. From the above results we obtained Stevia could be propagated by cutting method and the growth conditions including plant height, number of branches and content of stevioside were relatively better in S-2 and S-4 strains that were differentiated by the shape of leaf.

Two methods of constructing T-S fuzzy model which is equivalent to a given nonlinear system are presented. The first method is to obtain an equivalent T-S fuzzy model by using the sum of linearly independent scalar functions with constant real matrix coefficients. The sum of products of linearly independent scalar functions is used in the second method. The former method is to formulate the procedures of T-S fuzzy modeling dealt in many examples of previous publications; the latter is a new method. By comparing the number of linearly independent functions used in the two methods, we can easily find out which method makes fewer rules than the other. The nonlinear dynamics of an inverted Pendulum on a cart is used as an equivalent T-5 fuzzy modeling example.

In this paper, we propose the drowsiness detection method for car driver. This paper determines whether or not the driver's eyes are closed using the depth and infrared videos. The proposed method has the advantage to detect drowsiness without being affected by illumination. The proposed method detects a face in the depth picture by using the fact that the nose is closest to the camera. The driver's eyes are detected by using the extraction of harr-like feature within the detected face region. This method considers to be drowsiness if eyes are closed for a certain period of time. Simulation results show the drowsiness detection performance for the proposed method.
