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.

A leather quality inspection by naked eyes has known as unreliable because of its biological characteristics like accumulated fatigue caused from an optical illusion and biological phenomenon. Therefore it is necessary to automate the leather quality inspection by computer vision technique. In this paper, we present automatic leather qua1ity classification system get information from leather surface. Leather is usually graded by its information such as texture density, types and distribution of defects. The presented algorithm explain how we analyze leather information like texture density and defects from the gray-level images obtained by digital camera. The density data is computed by its ratio of distribution area, width, and height of Fourier spectrum magnitude. And the defect information of leather surface can be obtained by histogram distribution of pixels which is Windowed from preprocessed images. The information for entire leather could be a standard for grading leather quality. The proposed leather inspection system using machine vision can also be applied to another field to substitute human eye inspection.

Objective : The amount of hemorrhage observed on a brain computed tomography scan, or a patient's Fisher grade (FG), is a powerful risk factor for development of shunt dependent hydrocephlaus (SDHC). However, the influence of treatment modality (clipping versus coiling) on the rate of SDHC development has not been thoroughly investigated. Therefore, we compared the risk of SDHC in both treatment groups according to the amount of subarachnoid hemorrhage (SAH). Methods : We retrospectively reviewed 839 patients with aneurysmal SAH for a 5-year-period. Incidence of chronic SDHC was analyzed using each treatment modality according to the FG system. In addition, other well known risk factors for SDHC were also evaluated. Results : According to our data, Hunt-Hess grade, FG, acute hydrocephalus, and intraventricular hemorrhage were significant risk factors for development of chronic SDHC. Coiling group showed lower incidence of SDHC in FG 2 patients, and clipping groups revealed a significantly lower rate in FG 4 patients. Conclusion : Based on our data, treatment modality might have an influence on the incidence of SDHC. In FG 4 patients, the clipping group showed lower incidence of SDHC, and the coiling group showed lower incidence in FG 2 patients. We suggest that these findings could be a considerable factor when deciding on a treatment modality for aneurysmal SAH patients, particularly when the ruptured aneurysm can be occluded by either clipping or coiling.

Objective : This study performed to evaluate that duration of acne scars effects on Qualitative Global Acne Scarring Grading System(QGASC) grade changing and treatment duration. Also this study performed to evaluate the relationship between dysmenorrhea and acne scars, and the effects of each treatment on treatment duration and Korean Acne Grading System(KAGS) and QGASC grade.Methods : 95 patients with acne scars were understood by medical records and case photos, and we evaluated pre and post acne scar grade based on KAGS and QGASC. We analyzed data by SPSS 22 for windows program, and figured out the relation between duration of acne and QGASC grade and treatment duration by Spearman correlation analysis, and performed Mann-Whitney U-test to figure out the relation between dysmenorrhea and QGASC grade. We performed Wilcoxon test to evaluate that treatment of acne scars effects on KAGS grade and QGASC grade, and performed Kruskal-Wallis test to figure out the difference of each treatment which effects on KAGS grade and QGASC grade, and performed Post-hoc analysis to figure out the group comparison.Results & Conclusions : QGASC grade depending on duration of acne was statistically significance. Subcision and Microneedle Therapy System(MTS) and pharmacopuncture were significantly improved acne scars. Other treatments were significantly more effective than subcision and pharmacopuncture combined treatment. Treatment duration of Subcision and MTS combined treatment was significantly most shortest than other treatment.
