Recently, there is a big issue of downsizing on brake system according to fuel efficiency and regenerative braking cooperation control. Especially, small cars have improved in a variety ways such as electric vehicle and smart car compared to previous small cars. So, small brake system is strongly required in the car industry. A new small brake system for light compact vehicles was proposed in this paper. For this system, the solid type disc and caliper were newly developed. And the important design factors were considered to reduce brake size. First, we calculated the temperature rise of disc through heat capacity formula and CAE analysis. Second, we analyzed the housing and carrier stiffness of caliper to select the reasonable condition. Finally, the superiorities of the developed brake system were verified by heat capacity, consumption liquid level, braking feeling, judder, wear test and regenerative braking cooperation control analysis. A developed brake system is expected to be useful for brake system of light compact platform.

Microfluidic lab-on-a-chip (LOC) systems have enabled a new generation ofassay technologies in chemical and biomedical sciences. Caliper's microfluidic LOC systems contain a network of microscopic channels through which fluids and chemical are moved in order to perform experiments. The main advantages of these continuous-flow devices are integration and automation of multiple steps in complex analytical procedures to improve the reproducibility of the results, and eliminated the manual labor, time and pipetting errors involved in analyses. The present talk is devoted to give a brief introduction of microfluidic basics and to present in applying continuous-flow microchips to drug screening with model enzyme assays.

이 연구의 목적은 원추형 내측 연결 임플랜트 시스템에서 하중조건에 따른 지대주의 침하 및 적합도를 평가하는 것이다. 본 연구에서는 내부 원추형 연결방식의 Alloden implant system (Nei Corp. Korea)의 고정체와 2종류(conventional, FDI)의 지대주를 사용하였다. 임상에서 Alloden 임플랜트는 지대주와 고정체 연결시 처음에 손으로 지긋이 눌러 고정시킨 후 mallet을 이용하여 약 3회정도 타격을 가하여 고정한다. 이때 타격시의 정확한 힘을 측정하여 각 실험군에 적용시켰다. 적용 횟수는 손가락으로 누르는 힘을 1회, mallet으로 타격하는 힘을 3회, 저작력으로 가정한 20kg의 힘을 지대주의 침하가 생기지 않을때까지 각각의 표본에 적용하였다. 그 후 각 단계에 대한 지대주의 침하량을 Vernier caliper를 이용하여 측정하였다. 임플랜트는 불포화 폴리에스터(Epovia, Cray Valley Inc. Korea)에 매몰하여 중합시켰고 모든 표본을 절삭한 후 연마하여 주사전자현미경을 통하여 분석, 평가하였다.

Caliper intergrated Electric Parking Brake (EPB) is an automatic parking brake system, attached to rear caliper. Because EPB uses luxury vehicles recently, the drivers of vehicles are sensitive to the EPB noise. EPB is operated by the motor and gear, so noise is generated by motor and gear. In order to reduce noise, One of EPB manufacturers uses helical gear and changes the shape of EPB housing. But these methods are not optimized for reduction of interior noise. There are many noise transfer paths into vehicle interior and it is difficult to identify the noise sources. Therefore, in this study, we performed contribution analysis and modal testing in the vehicle system. It is possible to distinguish between air-borne noise and structure-borne noise in the vehicle interior noise by comparing interior noise peak with resonance mode map.

머리뼈 밑면의 높이는 영양상태와 건강조건에 크게 영향을 받는다. 귀밑점-으뜸점(Porion-basion)의 길이로 알려진 머리뼈 밑면의 높이는 캘리퍼(coordinate caliper)나 머리깊이(subtraction)를 계산하는 방법 등으로 쉽게 측정된다. 이 연구에서는 조선후기(17-18세기)와 6.25전쟁을 수행한 한국인의 영양상태와 건강상태를 알고자 하였다. 이를 위해 6.25전사자와 조선후기(17-18세기) 인골을 자료로 머리뼈 밑면높이의 변화정도를 살펴보고 변화에 영향을 끼친 요인이 무엇인지를 밝히고자 한다. 17-18세기 조선시대 회곽묘에서 출토된 인골모음과 6.25전사자 유해모음을 자료로 하였으며 비교는 미국에서 시기를 달리한 테리 인골모음과 법의학 인골모음을 사용하였다. 한국 인골모음의 경우 백인들과 비슷하거나 약간 낮으나 흑인보다는 건강상태가 좋은 것으로 관찰되는데 이는 민간계층가정에서 어린아이 성장에 필요한 영양을 효과적으로 공급하는 민간 재래적 방법 때문인 것으로 가늠된다. 그러나 조선 후기시대후기 인골의 영양상태는 일제하에서 성장한 6.25전사자와 별로 차이가 없다.

For the measurement of the fat contents and nutritional status of urban High School girls, an intensive examination was conducted on a total of 2,085 students from 13 to 19 years of age groups. Total body fat cotents were measured by Skin-fold thickness with a Skin-fold Caliper manufactured by Cambridge Scientific Industrial Inc. at four sites of the body and it was calculated by Kim's regression equation. And Heights, Weights, and Chest circumferences were measured with Martin's Anthropometer. As the results of this study, the following conclusions were obtained: 1. The averages of heights, weights and chest girths were 153.1 cm, 46.2 kg and 76.6 cm. respectively. 2. The mean Skin-fold thicknesses of each site measured with a Lange skin-fold Caliper were: Sub-scapular: $13.44\;mm{\pm}4.41\;mm$. Abdominal : $10.55\;mm{\pm}4.02\;mm$. Lumbar: $10.56\;mm{\pm}4.06\;mm$. Upper arm: $15.35\;mm{\pm}4.37\;mm$. Total Average: $12.46\;mm{\pm}4.48\;mm$. 3.

PURPOSE. The objective was to evaluate canine positions, intercanine tip width (ICTW) and width of distal surface of canine (WDC), related to facial landmarks including interalar width (IAW), intercommissural width (ICoW), and distance between left and right projection lines drawn from inner canthus of eyes to alae of the nose (DPICa) in a group of Thai. MATERIALS AND METHODS. One hundred Thai subjects aged 18-35 years were selected. IAW and ICoW were measured on subject's face using digital vernier caliper. Irreversible hydrocolloid impression of the upper arch was taken, and a cast was poured with dental stone. Silicone impression material was used to take imprint of the incisal edge of upper six anterior teeth. DPICa was obtained from the subject's face using custom-made measuring equipment and marked on the silicone incisal imprint. The marks were then transferred from the imprint to the stone cast and measured with digital caliper. The ICTW and WDC were also measured on the stone cast. Pearson's correlation was used to determine the correlation. RESULTS. The results revealed that the correlation between ICTW-ICoW was 0.429 and ICTW-DPICa was 0.573. The correlation between WDC-ICoW was 0.426 and WDC-DPICa was 0.547. However, IAW did not show any correlation with ICTW or WDC (P>.05). CONCLUSION. The correlation between canine position and facial landmarks was found. ICTW and WDC had relationship with ICoW and DPICa. DPICa showed stronger correlation with the position of maxillary canine than that of ICoW.
