Objectives : This study was to observe clinical application of auto-microneedle therapy system (AMTS) in patients with peripheral facial paralysis. Methods : 27 peripheral facial paralysis patients were observed after taking AMTS at Facial Palsy Center, Kyung Hee University Oriental Medicine Hospital from March 1, 2011 to January 9, 2012. We assessed the symptoms of facial paralysis with Yanagihara unweighted grading system, Sunnybrook facial grading system(SBGS) and facial disability index(FDI), and observed adverse events and total safety of the treatment. Results : The scores of facial palsy scales increased after AMTS in Yanagihara grading system and Sunnybrook facial grading system. AMTS-related adverse events were mild pain(5.9%) and fatigue(3.5%), which needed no extra treatment. The total safety evaluation was between 'safe' and 'nearly safe' level. There were no other serious adverse events. In addition, patients were satisfied with subjective improvement including facial tingling and numbness. Conclusions : AMTS can be applied as an adjunctive treatment for patients with peripheral facial paralysis due to its safety and clinical usefulness. It is easier to stimulate wide skin area in a short time. Further clinical research is required to investigate the effectiveness of ATMS in a more rigorous RCTs.

Purpose: A robust, efficient auto-grading computer vision system for meat carcasses is in high demand by researchers all over the world. In this paper, we discuss our study, in which we developed a system to speed up line processing and provide reliable results for pork grading, comparing the results of our algorithms with visual human subjectivity measurements. Methods: We differentiated fat and lean using an entropic correlation algorithm. We also developed a self-designed robust segmentation algorithm that successfully segmented several porkcut samples; this algorithm can help to eliminate the current issues associated with autothresholding. Results: In this study, we carefully considered the key step of autoextracting lean tissue. We introduced a self-proposed scheme and implemented it in over 200 pork-cut samples. The accuracy and computation time were acceptable, showing excellent potential for use in online commercial systems. Conclusions: This paper summarizes the main results reported in recent application studies, which include modifying and smoothing the lean area of pork-cut sections of commercial fresh pork by human experts for an auto-grading process. The developed algorithms were implemented in a prototype mobile processing unit, which can be implemented at the pork processing site.

캐드(CAD) 시스템은 우리가 사용하는 대부분의 산업 제품을 제작하는데 필수적으로 사용되고 있는 중요한 기술로 알려져 있다. 캐드 기술은 컴퓨터 그래픽스 기술의 발달과 더불어 상업용 3차원 캐드 시스템으로 영역을 확장해 나가고 있다. 특히, 신발제조와 같은 특수한 영역의 캐드 시스템들도 3차원 캐드로 발전해 나가고 있다. 그러나 캐드 소프트웨어의 개발의 어려움으로 인해 소수의 메이저급 캐드 소프트웨어 회사를 제외하고는 대부분이 3차원 개념을 제공하는 AutoCAD에 종속적인 소프트웨어를 개발하고 있다. 뿐만 아니라 실제의 작업 현장에서 일하는 많은 신발 캐드 디자이너들은 직접 신발 디자인을 종이에 그리는 교육을 받아 3차원 캐 보다는 2차원 캐드에 더 익숙하고, 작업 효율도 훨씬 뛰어남을 보이고 있다. 이에 본 연구에서는 현장 실무자들의 작업 방식과 3차원 캐드 소프트웨어가 주는 장점을 결합한 3차원 신발 캐드 시스템을 설계 할 것이다. 본 시스템은 다른 신발 캐드 시스템들과 달리 OpenGL을 기반으로 하여 어느 플랫폼에서 잘 작동하도록 설계할 것이다. 또한 3차원 신발 설계 시스템에서 가장 중요한 부분인 3차원 캐드데이터와 2차원 캐드 데이터의 호환 방법을 제시하고, 다양한 크기의 신발 제작에 필수적인 여러 할출(grading) 기법을 제시할 것이다.

Purpose: Postharvest handling of onions (harvesting, cleaning, grading, cooling, storing, and transport) should be performed continually to reduce costs and improve quality. The purpose of this study is to a) determine the design parameters and operating conditions of anion auto-dumping that constitutes a key component of the postharvest bulk handling machinery system, and b) to perform a performance test with the auto-dump prototype system. Methods: Kinematic analyses and computer simulations of the auto-dump mechanism were applied to analyze the operating conditions and design parameters. Results: The optimum working condition for the auto-dump was determined from kinetic analyses. In addition, the interaction between the velocity of the hydraulic cylinder and the angular velocity of the auto-dump were analyzed in order to control the bulk handling machinery system. The acting forces and optimum operating conditions of the hydraulic cylinder were determined by analyzing the forces related to the mass of inertia of the auto-dump assembly during rotation. The method of controlling the feeding rate of onions in terms of the uniformity of the stacking pattern and the control of the entire system was better than the two-stage method of controlling the rotational speed of the auto-dump. Based on the performance test with the prototype for the auto-dump, the stacking pattern and rigidity of the system were analyzed. Conclusions: These results would be of great importance in the postharvest bulk handling machinery system for onions.

The objective of this study was to investigate slaughtering performance, carcass grade, and quantitative traits of cuts according to seasonal influence by each month in pigs slaughtered in livestock processing complex (LPC) slaughterhouse in Korea, 2017. A total of 267,990 LYD ($Landrace{\times}Yorkshire{\times}Duroc$) pig data were used in this study. Results of slaughter heads, sex distribution, carcass weight, backfat thickness, grading class, total weight, and fat and lean meat percentages of each cut predicted by AutoFom III were obtained each month. The number of slaughtered pigs was the highest in early and late fall but the lowest in midsummer. Only in midsummer that the number of females was higher than that of castrates. During 2017, carcass weight was the lowest in late summer. Backfat thickness was in the range of 21-22 mm. In mid and late spring, pigs showed high 1+ grade ratio (37.05% and 36.15%, respectively). For traits of 11 cuts predicted by AutoFom III, porkbelly showed lower total weight, lean weight, and fat weight in midsummer to early fall but higher lean meat percentage compared to other seasons. Weights of deboned neck, loin, and lean meat were the highest in midfall compared to other seasons (p<0.05). In conclusion, characteristics of slaughtering, grading, and economic traits of pigs seemed to be highly seasonal. They were influenced by seasons. Results of this study could be used as basic data to develop seasonal specified management ways to improve pork production.

An intelligent excavator can be divided into Machine Guidance (MG), semi-automatic, and unmanned by technology. The MG technology excavator is equipped with a tilt sensor on each link of the excavator and a GPS is installed on the excavator body to inform the user of the position of the excavator bucket end. Machine control (MC) technology that assists the user's work can be divided into semi-automatic and fully automatic technology. The semi-automatic MC equipment has already been commercialized by Komatsu and Caterpillar. The MC excavator is equipped with an electro-hydraulic system, sensors and controllers to control the excavator bucket end according to the user's needs. In this study, the semi-automated excavator modified based on manual excavator, is equipped with an electro-hydraulic system, a controller system, multi-sensors and a control algorithm is developed to assist in excavation work such as leveling and grading. By applying the developed technology, it was possible to confirm productivity improvement compared to manual digging and leveling work. In the future, further research to improve the accuracy of the hydraulic precision control and collaborative work with heterogeneous construction equipment such as dump truck and automated collaboration tasks technology could be developed.

본 연구는 홍삼 등급 판정을 위한 내부 상태 및 조직의 치밀도 분석 방법에 관한 것이다. 홍삼 내부 측정을 위해 1990년대 이후부터는 자기공명영상법(MRI), X-ray 판별 등의 비파괴 검사 방법에 대한 연구가 다양하게 이루어졌지만, 등급 판정에 가장 중요한 내공(內空), 내백(內白)을 파악하는데 어려움이 있어 정확한 내부 판정이 불가능하였다. 그리하여 본 연구에서는 적외선 조명 환경의 폐쇄형 영상 취득 장치를 제작하고 내공, 내백의 유무와 직경을 파악할 수 있는 내부 측정 시스템을 개발하였다. 제작한 장치는 홍삼 내부 투과율이 높은 950nm 파장대역의 적외선 조명, 적외선 대역 촬영이 가능한 카메라, 카메라에 홍삼의 초점을 자동제어 할 수 있는 Y축 제어 액추에이터 그리고 홍삼을 $1^{\circ}$의 간격으로 $360^{\circ}$ 회전하며 영상을 취득할 수 있는 회전 액추에이터로 구성이 되어있다. 제안하는 알고리즘은 Y축 액추에이터에서 Auto-Focus 알고리즘을 수행하여 홍삼의 크기와 두께 변화에 따라 객체의 선명한 초점을 자동으로 맞춰준다. 그다음 홍삼을 $1^{\circ}$ 간격으로 $360^{\circ}$ 회전하며 총 360장의 홍삼 영상을 취득하면 라돈 변환(Radon transform)을 통해 사이노그램(Sinogram)으로 재구성하고, 역 라돈 변환(Inverse Radon transform)을 통해 단층영상복원(Back-projection) 알고리즘이 수행되어 홍삼 내부 영상을 획득하였다. 알고리즘 수행 결과 홍삼 두께나 모양에 관계없이 내부 단면영상 획득이 가능하였고 영상을 통해 내공, 내백의 유무와 직경을 파악할 수 있었다. 추후 10,000개 이상의 다양한 모양과 크기를 가지는 홍삼에 대하여 내부 영상을 취득하여 등급 판별 기준을 적용한다면 신뢰성 있는 홍삼 등급 자동화 측정 방법으로 사용가능 할 것이다.
