Objectives : The mechanical properties of Korean electric cupping systems are studied via experimental measurements. The study aimed at establishing the fundamentals of industrialization and systemization of oriental medicine device industry, as well as improving the quality of life for many Koreans. Methods : We reviewed the studies on traditional cupping as well as modern one to fine necessary factors for electric cupping systems. To characterize the mechanical properties of Korean electric cupping systems, we measured the pressure characteristics of commercially available electric cupping system by using an automatic pressure acquisition system and a standard cup. The pumping capability was checked at 40 seconds, and the stability of the suction cup was checked at 600 seconds. We also acquired the noise level of each system in clinical setting. To check the portability of each system, we also measured its physical dimensions. We scrutinized system manuals provided by the system manufacturers. Results : It took less than 5 second to reach the pressure if the connection between the air hose and the vacuum valve of the cupping system was secure. Pressure diminished to no more than 10% for 600s for all systems. Noise levels were 55~70 dB. Increase in pressure was too fast to control for a designated vacuum level except for one product. Conclusions : The Pumping ability of the systems is impressive and reliable. Pressure retention ability of each cup is quite reliable and reproducible. Therefore, their mechanical performances were worthy of recommendation. Some of them had noise level higher than 60 dB and they were bothersome. It was also suggested that the control for low to middle pressure needed to be accomplished by the cupping system.

The mechanical and impact properties of the stitched Spectra composite was studied. The Spectra fiber reinforced vinylester composites were stitched with plain stitch to improve mechanical and impact resistant properties. The Spectra liber was used as a stitching thread and the composites were stitched twice in alternating sequence with plain stitch. The stitched composite showed different behavior with stitch densities in tensile and flexural properties. The effect of stitching has been changed with the mechanical properties measured under different restrained condition. The stitching has improved the preserving properties of the woven laminate composite structure by restricting the damage propagation.

RTCVD법으로 증착된 다결정 Si$_{1-x}$Ge$_{x}$박막에서 Ge조성 증가에 따른 결정립크기변화가 표면거칠기 및 cluster크기에 미치는 영향에 대해 알아본결과, Ge조성 증가에 따라 결정립크기가 증가했으며 증가된 결정립에 의해 Cluster 크기와 표면거칠기값(RMS)들이 증가함을 알 수 있었다. 또한 증착된 다결정 Si$_{1-x}$Ge$_{x}$박막을 RF power와 온도변화에 따라 Ar/H$_{2}$플라즈마를 이용한 수소화처리를 행하여, 수소화 효과와 표면거칠기값 그리고 비저항값 변화에 대해 조사하였다. 수소화처리 후 cluster크기와 표면거칠기값은 기판온도와 RF power 증가에따라 감소함을 알 수 있었으며 특히 기판온도 30$0^{\circ}C$에서는 비저항값이 상당히 증가하였다.

Purpose: This study investigates the effect of CRM activities of Korean equipment construction companies on the quality satisfaction perceived by consumers as an analysis method using Kano model. Methods: It use the Kano model to classify the quality characteristics of the CRM activities of equipment construction companies, focusing on consumer perception, and analyze the effect on the level of quality satisfaction perceived by consumers. Results: The results showed that most of quality attributes of CRM activities in the equipment companies were categorized as 'one-dimensional' quality. Conclusion: The CRM activities in equipment construction compaies is verified to be essential component of successful strategy to improve customer's satisfaction.

Proper operation of the battery powered systems depends on the accuracy of the battery SOC(State of Charge) estimation, therefore it is critical for those systems that SOC is accurately determined. The SOC of the battery is related to the battery aging and the SOC estimation methods without considering the aging of the battery are not accurate. In this paper, a new method that accurately estimate the SOC of the battery is proposed considering the aging of the battery. A mathematical model for the Battery SOC-OCV(Open Circuit Voltage) relationship is presented using Boltzmann equation and aging indicator is defined, and then the SOC is estimated combining the mathematical model and aging indicator. The proposed method takes the aging of the battery into consideration, which leads to an accurate estimation of the SOC. The simulations and experiments show the effectiveness of the proposed method for improving the accuracy of the SOC estimation. 배터리를 사용하고 있는 시스템에서 배터리의 잔존 용량에 대한 정보는 매우 중요하며, 따라서 정확한 SOC(State of Charge)의 추정이 필요하다. 배터리는 노화됨에 따라 전체 사용 가능 용량이 줄어들고 성능이 떨어지는데 이러한 노화의 영향을 고려하지 않는 배터리의 SOC 추정 방법은 추정의 정확도가 떨어지는 단점이 있다. 따라서 본 논문에서는 배터리의 노화 상태를 고려하여 배터리의 SOC를 추정하는 새로운 방법을 제안한다. 제안한 방법에서는 배터리의 전압-SOC 특성 곡선을 Boltzmann 방정식을 사용하여 모델링하고 노화 지표를 정의하며, 노화 지표를 Boltzmann 방정식 모델과 결합하여 SOC를 추정한다. 따라서 제안한 방법은 배터리의 노화 상태를 SOC 추정에 반영하여 노화된 배터리에 대한 정확한 SOC 추정이 가능하다. 또한 새 배터리와 1년 사용한 배터리에 대한 실험과 시뮬레이션을 통하여 제안한 방법의 유효성을 확인한다.

Password with a combination of 4-digit numbers has been widely adopted for various authentication systems (such as credit card authentication, digital door lock systems and so on). However, this system could not be safe because the 4-digit password can easily be stolen by predicting it from the fingermarks on the keypad or display screen. Furthermore, due to the prolonged COVID-19 pandemic, contactless method has been preferred over contact method in authentication. This paper suggests a new password input method based on eyeblink pattern analysis in video sequence. In the proposed method, when someone stands in front of a camera, the sequence of eyeblink motions is captured (according to counting signal from 0 to 9 or 9 to 0), analyzed and encoded, producing the desired 4-digit decimal numbers. One does not need to touch something like keypad or perform an exaggerated action, which can become a very important clue for intruders to predict the password.
