  • In this paper, the bearing strengths and fracture behaviors of the pin-jointed carbon fiber/epoxy composites were investigated through pin loading test with acoustic emission technique. The composites were fabricated by a filament winding process, and three types of laminated patterns were considered. Type 1 was fabricated with stitch, Type 2 was fabricated without stitich and Type 3 was fabricated with prepregs. According to the results, bearing strength of Type 1 was 3.3% lower than that of Type 2 and that of Type 3 was highest. Type 1 and Type 2 revealed a net-tension failure mode, respectively, whereas Type 3 pattern exhibited a bearing failure mode. Also, acoustic emission energy of the Type 3 was higher than that of the Type 1 and Type 2. Therefore, the Type 3 was found to be structurally safer than the Type 1 and Type 2.

  • Cultivation using rain shelter is very popular in summer because rain shelter has a simple structure using less materials than any other regular greenhouse. Although it has a main advantage of easy construction in terms of labour, time and cost, it has some disadvantage of poor ventilation and rain fall inflow. Therefore, the rain shelters being able to overcome the problems, to some extent, are necessary to propagate for practical purpose. Three characteristic types of rain shelter were analyzed using measured and simulated environment data. Type 1 was a conventional type with an arched roof, and Type 2 and Type 3 were improved ones which were designed to have three arched roofs and three sawtooth like roofs with the openings for ventilation, respectively. The distribution of inside temperature measured was relatively uniform in Type 2 and 3 by the natural ventilation through the openings of the roof compared to Type 1 which had no openings. The relative light transmittance measured in Type 2 and 3 showed lower than that in Type 1, which suppressed the rise of inside temperature, For more accurate comparison, the differences between inside and outside temperatures to various wind speeds were calculated by the model. The difference in Type 1 was the greatest at lower wind speed below 1 ㎧, that is, the highest in inside temperature, but decreased rapidly as wind speed increased above 1 ㎧. Measured temperatures generally showed the same trends as calculated ones by the model. As a whole, the improved rain shelters(Type 2 and 3) showed better performance than the conventional one in ventilation as well as inside temperature.

  • This experiment was conducted to investigate the influence of temperature variation by the different ventilation methods on the growth and quality of oriental melon in greenhouse of tunnel type 1. The dropping effect in temperature by ventilation types was best at type 3 and those of type 2, type 1 were in order. 2. The temperature distribution in type 3 was uniformed as air- inflow and air- outflow by wind ventilation were easier than others. Whereas the temperature of type 1 having lateral ventilation hole and type 2 having the zenith ventilation tube and lateral ventilation hole was ascended, because small ventilation area of ventilation tube and hole could not make the gravity and wind ventilation successfully. 3. When compared with air amount of three types ventilated by the temperature difference of outside and inside of tunnel type house, that of type 3 was more than those of type 1 and type 2. 4. Type 3 was better than type 2 and type 1 in lear numbers, leaf area, fruit weight, flesh thickness, malformed fruit rate, and marketable fruit rate. 5. Marketable fruit rate of all treatment at each harvesting stages was rised, as goes to the latter periods.

  • The disc plate and frame type modules for reverse osmosis were developed using three different types of baffles: linear (Type 1), curved (Type 2) and parallel shapes (Type 3). Separation performance tests were carried out for the modules using NaCl and sucrose solutions under the various concentrations and operating pressures. The permeation flux and solute rejection ratio for Type 3 module were the highest within operating pressure (35bar) and flow rate (6 l/min). The flux improvement ratio of Type 2 or 3 to Type 1 for NaCl solution decreased as operating pressure increased: flux improvement ratios of Type 3 for 1wt% of NaCl solution were about 100 and 10% at 10 and 35bar, respectively. However, the flux improvement ratio for sucrose solutions varied with the operating pressure and concentration. The permeation flux for Type 3 depended on the flow rate linearly, which is higher than that of turbulent flow region in the smooth channel.

  • 한국산 체꽃속(Scabiosa L.)의 외부형태형질을 바탕으로 구분한 5가지 변이 유형[솔체꽃(S. comosa) Type 1-2, 체꽃(S. tschiliensis f. pinnata) Type 3-4, 구름체꽃(S. tschiliensis f. alpina) Type 5]에 대해 잎 표피와 화분의 미세구조를 관찰하였다. 잎 표피세포의 크기는 향축면은 평균 12.4 × 6.7 ㎛로, Type 1이 가장 작고 Type 3가 가장 컸으며, 배축면은 평균 9.4 × 4.6 ㎛로 모든 유형이 비슷하게 나타났다. 모용은 단세포성 선상 모용이 일부 유형에서, 다세포성 비선상 모용이 모든 유형에서 관찰되었다. 선상 모용은 향축면에서 Type 1과 5에만 있었으며, 두 유형 중 Type 5의 모용이 길이 72.2 ㎛로 더 길고, 단위면적 (0.01 mm2) 당 개수도 5개로 더 많았다. 배축면에서는 Type 1, 3 및 5에 있고, 단위면적 당 개수가 Type 1과 5는 3~6개로 비슷하였으나, Type 3은 1개 이하로 매우 드물게 나타났다. 기공복합체는 부등형으로 양면에 분포하며, 향축면의 공변세포 크기는 평균 4.4 × 2.7 ㎛로 너비는 유사하나 길이는 Type 1과 5가 3.1 ㎛, 3.9 ㎛로 나머지에 비해 작았다. 단위면적 당 기공의 수는 향축면과 배축면이 평균 40.2개, 149.2개이고, 양면 모두 Type 1이 66.3개와 177.2개로 가장 많았다. 화분은 모두 단립으로 삼구형이고, 극축 길이(P)와 적도면 지름(E)의 비율은 0.83~1.12로 모양은 아단구형~약장구형이다. 표면무늬는 과립상 표면에 자상 돌기가 있고, Type 3과 4에서만 유공상이 확인되었다. 이상의 결과에서, 솔체꽃 유형인 Type 1과 2가 잎 표면의 선상 모용 유무 및 기공의 수에 뚜렷한 차이를 보여 Type 1은 솔체꽃과는 다른 새로운 변종 또는 품종일 가능성이 있다고 생각된다. 또한 체꽃 유형인 Type 3과 4의 경우, Type 3의 잎 배축면에 털이 드물게 있으나, 두 유형의 화분 표면무늬가 동일하고, 다른 형질들도 모두 중복되어 연속적인 변이로 보이며, 구름체꽃 유형인 Type 5는 나머지 유형과 뚜렷이 구분되었다.

  • This paper presents a method to estimate subpixel accuracy motion vectors using a mathermatical model withoug interpolation. the proposed method decides the coefficients of mathematical model, which represents the motion vector which is achieved by full search. And then the proposed method estimates subpixel accuracy motion vector from achieved mathematical model. Step by step mathematical models such as type 1, type 2, type 3, modified bype 2, modified type 3, and Partial Interpolation type 3 are presented. In type 1, quadratic polynomial, which has 9 unknown coefficients and models the 3by 3 pixel plane, is used to get the subpixel accuracy motion vectors by inverse matrix solution. In type 2 and 3, each quadratic polynomial which is simplified from type 1 has 5 and 6 unknown coefficients and is used by least square solution. Modified type 2 and modified type 3 are enhanced models by weighting only 5 pixels out of 9. P.I. type 3 is more accurate method by partial interpolation around subpixel which isachieved by type 3. LThese simulation results show that the more delicate model has the better performance and modified models which are simplified have excellent performance with reduced computational complexity.

  • This study was designed to testify the possibility and devise the method to manipulate the 3D body scan data to produce rounded-belt pattern adaptable to hip-type variation of women in their 20's. The results of this research were as follows : Firstly, based on drop-value distribution of hip and waist girth, 151 subjects were classified into three hip-types; Type 1 (15.23%) was 'cylinder type', showing lowest drop-value, Type 2 (69.54%) was 'average type' and Type3 (15.23%) was 'hourglass type' showing highest drop-value. Secondly, using CAD program, design lines for round shape belt were set on the surface of 3D scan data of representative subject of each type. And divided 3D surfaces were flattened onto the plane by the internal tools of CAD program. The measure, 'lifting value of round belt pattern', implying the level of curve ratio of pattern was higher in back than front. This result might be linked to the fact that the hip part is more protruded than the abdomen part. And the measures also showed highest values in Type 3(hourglass type) and lowest in Type 1(cylinder type), meaning that the pattern of Type 3 showed more rounded shape than that of Type 1. This finding implied that round belt for body type having high drop-value should be shaped more curved. Thirdly, difference ratios of outline length and area between 3D curves(body surface) and 2D plane(pattern) were 4.5% and 1.3%, respectively. This result demonstrated and solidified the feasibility of designing digital garment pattern from 3D body scan data.
