위에 발생하는 악성종양 중 원발성 위림프종은 상당히 드문편으로 동시에 간세포암이 병발한 경우는 매우 드물다. 본 증례는 원발성 위림프종과 간세포암의 병발로 진단된 46세 남자에 대한 보고로서 각각의 종양에 대하여 조직검사 및 면역조직화학 검사를 시행하여 진단하였다. 림프종에 대하여는 R-CHOP 항암화학요법(rituximab, cyclophosphamide, doxorubicin, vincristine, prednisolone)을 시행하여 완전관해를 하였고, 항암화학요법 중간에 간동맥 화학 색전술 및 간좌엽 절제술을 시행하여 간세포암에 대한 근치적 치료를 시행하였고, 현재 추적관찰 중이다. Primary gastric lymphoma is relatively rare in the context of gastric malignancies. Synchronous primary gastric lymphoma and hepatocellular carcinoma (HCC) are even rarer. We report a case of synchronous primary gastric lymphoma and HCC in a 46-year-old man that appeared to be associated with hepatitis B virus infection. Pathologic examination and immunohistochemical analysis of gastric and liver specimens showed diffuse large B-cell lymphoma and HCC, respectively. The patient was initially treated for primary gastric lymphoma with R-CHOP (rituximab, cyclophosphamide, doxorubicin, vincristine and prednisolone) chemotherapy. During the chemotherapy interval, he was treated for HCC by transarterial chemoembolization (TACE) and laparoscopy-assisted left hemihepatectomy. (Korean J Med 2011;81:403-407)

The tool wear and failure in automatic production system directly influences the quality and productivity of a product, thus it is essential to monitor the tool state in real time. For such purpose, an ART2-based remote monitoring system has been developed to predict the appropriate tool change time in accordance with the tool wear, and this study aims to experimently find the relationship between the tool wear and the monitoring signals in cutting processes. Also, the roughness of workpiece according to the wool wear is examined. Here, the tool wear is indirectly monitored by signals from a vibration senor attached to a machining center. and the wear dimension is measured by a microscope at the start, midways and the end of a cutting process. A series of experiments are carried out with various feedrates and spindle speeds, and the results show that the sensor signal properly represents the degree of wear of a tool being used, and the roughnesses measured has direct relation with the tool wear dimension. Thus, it is concluded that the monitoring signals from the vibration sensor can be used as a useful measure for the tool wear monitoring.

Objectives The purpose of this study was to compare the effects of MSAT (Motion style acupuncture treatment) using Sandbag regarding low back pain with HIVD of L-SPINE. Methods Forty patients received inpatient treatment from March 16 to May 16, 2015 in the Daejon-Jaseng oriental medicine hospital were divided into 2 groups by blocked randomization: Group A (n=20) is routine treatment on HIVD of L-SPINE with MSAT using Sandbag and Group B (n=20) is routine treatment on HIVD of L-SPINE (acupuncture, Shinbaro pharmacopuncture, herb medication, chuna treatment and physiotherapy). The MSAT (Motion style acupuncture treatment) using Sandbag was administered each day and both groups were received routine treatment each day. Evaluations were made before treatment, after 3 days and 7 days, and before discharge using the NRS (numeric rating scale) and ODI (oswestry disability index). The statistically significance was evaluated by SPSS 22.0 for windows. Results The NRS (numeric rating scale) and ODI (oswestry disability index) of both A and B groups after 3, 7 days and before discharge of treatment significantly decreased (p <0.05). Regarding group comparison, the NRS (numeric rating scale) and ODI (oswestry disability index) of A group was significantly lower than the B group at 3, 7 days, before discharge (p<0.05). Regarding improvement of the NRS (numeric rating scale) and ODI (oswestry disability index), A group was significantly lower than the B group at 3 day (NRS), 7 day (ODI) (p<0.05). There was significant difference between two groups at 7 days (NRS) and before discharge (p<0.05). Conclusions Compared to routine treatment, the MSAT (Mostion style acuputure treatment) using Sandbag significantly improved the NRS (numeric rating scale) and ODI (oswestry disability index) after 3, 7 days, and before discharge. Because early intervention determines the grade of Low back pain with HIVD of L-SPINE, the MSAT (Motion style acupuncture treatment) using Sandbag will be clinically helpful to patients at the early stage.
