연구목적: 정신분열병 환자의 사회적응 정도를 측정하는데 사용되는 사회적응 척도의 한국어판을 개발하기 위함이다. 방 법: 사회적응 척도를 번역한 후 정신분열병 환자 67명과 정상인 78명을 대상으로 신뢰도와 타당도를 검증하였다. 결 과: 자료분석 결과 검사-재검사 신뢰도는 0.85, 검사자간 신뢰도는 0.89, 내적 일치도는 0.87로 높은 수치였다. 변별 타당도를 검증하기 위하여 정신분열병 환자군과 정상 대조군을 비교한 결과 정신분열병 환자군에서 사회적응 정도가 유의하게 낮았다. 구성 타당도를 알아보기 위하여 10개 영역간의 상관관계를 측정한 결과 성적적응 영역을 제외한 모든 영역들에서 유의한 상관관계를 보였다. 본 척도의 전반적 평가 영역 결과와 GAF 결과간의 상관성을 통해 간접적으로 검증한 공존 타당도 역시 유의하였다. 결 론: 한국판 사회적응 척도는 우수한 신뢰도와 타당도가 입증되었고 나아가 정신분열병 환자의 사회적응 정도를 평가하는데 유용하게 사용되어질 수 있을 것이다. Objectives: The purpose of this study was to develop the Korean version of the Social Adjustment Scale Ⅱ-Revised Version(KSAS Ⅱ-RV) in the schizophrenics. Methods: KSAS Ⅱ-RV was administered to 67 schizophrenic patients and 78 matched normal controls for examining the reliability and validity. Results: Data analysis showed statistically significant reliabilities and validities of KSAS Ⅱ-RV. The test-retest reliability, inter-rater reliability, and internal consistency for total scores of KSAS Ⅱ-RV were 0.85, 0.89. and 0.87, respectively. Evidence for discriminant validity of KSAS Ⅱ-RV comes from the results that the mean scores of schizophrenic patients were significantly high than those of normal controls. Construct validity was assessed by calculating the 10 inter-subareas correlations of the KSAS Ⅱ-RV, and all except the sexual adjustment area were statistically significant. Significant correlations between the global area scores of KSAS Ⅱ-RV and those of Global Assessment of Functioning Scale lend support for the concurrent validity of this instrument indirectly. Conclusions: KSAS Ⅱ-RV was found to be a valid and reliable instrument which can be used to evaluate the degree of social adjustment in the schizophrenic patients.

J. J. KIM, M. H. LEE, Y. J. KIM, W. S. CHAE, Y. S. HAN, O. KWON. Comparison of the maximum EMG levels recorded in maximum effort isometric contractions at five different knee flexion angles. Korean Journal of Sport Biomechanics, Vol. 15, No. 1, pp. 197-206, 2005. The purpose of this study was to quantify the maximum EMG levels and determine if there are differences in these EMG levels with respect to different knee flexion angles. Eight university students with no known musculoskeletal disorders were recruited as the participants. The maximum voluntary isometric knee extensions and flexions were taken from each participant sat on the isokinetic exercise machine (Cybex 340) at five different knee flexion angles (10?30?50?70? 90?. After surface electrodes were attached to rectus femoris, vastus medialis, vastus laterlis, biceps femoris, and semitendinosus, maximum EMG levels at five different knee flexion angles were measured. The results showed that there was no significant difference in maximum EMG levels among five different knee flexion angles. Although there was no significant difference in EMG levels and were some variations among different knee flexion angles, the EMG signals of quadriceps in extension and biceps femoris in flexion were the greatest at 30? It seems that different joint angles or relative locations of body segments might affect the magnitude of EMG levels. Because the maximum EMG levels could change with a different knee flexion angle, an attempt should be made to more accurately measure these values. If then, %MVIC measure provides more reliable data and is most appropriate for EMG normalization.

Multiple bilobar liver matastases (MBLM) are the main cause of low resectability in the colon cancer liver metastases. The authors experienced one case of initially non-resectable colon cancer liver metastases. He was curatively and safely treated with a two-stage hepatectomy using the new method of future remnant liver volume growing. A 54-year-old man was referred to our department with the sigmoid colon cancer combined with MBLM, which were checked in two small metastatic lesions in the left lobe and five large sized lesions in the right lobe in the computed tomogram (CT). A laparoscopic assisted anterior resection was primarily performed. We performed the 1^(st) stage hepatectomy 3 weeks after the colon resection. Intra-operative Ultrasonogram (US) found 9 small superficial metastatic lesions in the left lobe. All that lesions were completely removed by non-anatomical wedge resection. An occlusion ballon catheter was placed in the right portal vein through a small branch of the inferior mesenteric vein at that time. The future remnant liver volume was sufficiently increased 3 weeks after the 1^(st) hepatectomy. A right hepatectomy was safely performed 22 days after the 1^(st) hepatectomy. The patient received a regional chemotherapy (interleukin2 based immuno-chemotherapy through hepatic artery) for 4 months, then received 9 cycles of systemic chemotherapy (biweekly Oxaliplation, leucovorin, plus 5-fluorouracil) without any recurrence evidence.

Rack-Level DC Power Solution for Volume Servers

Won-Ok Kwon,Hae-Moon Seo,최평 한국전자통신연구원 2010 ETRI Journal Vol.32 No.6

Rack-level DC power supply is the optimal technology for providing DC power to a volume server without any power infrastructure changes in an existing AC data center. In this paper, we propose a smartly controllable and monitorable DC rack power system. The proposed system improves power efficiency by changing the power distribution architecture of a conventional method in the rack. We developed an optimal power control method in multipower modules to provide high efficiency at low loads. In addition, the proposed system provides real-time web monitoring of the rack power and environment around a rack. In our experiments, the proposed system improved the power efficiency by over 10% compared to an AC power system providing N+1 redundant power and power monitoring.

Won Ok Kwon,Hae Moon Seo,Pyung Choi 한국전자통신연구원 2011 ETRI Journal Vol.33 No.4

This letter presents a highly efficient rack-level DC power architecture combined with a node-level DC uninterruptible power supply (UPS). The proposed system can provide almost the equivalent power efficiency of a high-voltage DC data center without any change in the existing power infrastructure. The node-level DC UPS combined with a power distribution board provides high power efficiency as well as lower UPS installation costs. Implemented on a rack, the entire power system can be monitored through a network.

<P><B>Abstract</B></P> <P>People are interested in eating good foods as a way of increasing their quality of life. Research conducted on the quantitative detection and characterization of the taste components of foods has received significant attention in recent years. However, taste sensors with higher sensitivities are needed because the expectations of the public are constantly increasing. In this study, a cascoded gated lateral bipolar junction transistor (C-GLBJT) was developed and used in taste sensor applications for detecting five taste substances. The results showed that the sensitivity of the C-GLBJT taste sensor was 0–2.55μA/decade, and it can detect very low concentrations (down to 1fM) of five taste solutions. The developed integrated C-GLBJT sensor could be able to provide more precise information about foods to consumers and patients who are interested in their well-being. Also, it may be of great help to advertisers and businessmen by providing them with reproducible quantitative information about their products.</P> <P><B>Highlights</B></P> <P> <UL> <LI> The cascaded gated lateral bipolar junction transistor (C-CLBJT) that has the high transconductance was developed and used in the taste sensor. </LI> <LI> The proposed taste sensor can detect five kinds of taste solutions which are very low concentration up to 1fM. </LI> <LI> Also, the proposed taste sensor has the sensitivities of 0–2.55μA/decade according to the types of lipid sensing membranes. </LI> <LI> The measuring capability of the proposed sensor is very large, and it can detect concentrations that are lower than the 1μM limit of human’s limit. </LI> <LI> Therefore, it can satisfy human expectations and may be of great help to enterprises through the quantification of the five kinds of tastes. </LI> </UL> </P> <P><B>Graphical abstract</B></P> <P>[DISPLAY OMISSION]</P>

Emphysematous pyelonephritis (EPN) is a life-threatening infection characterizedby the formation of gas. Complications of EPN include septic shock, acuterenal failure, and disseminated intravascular coagulation. Spontaneous subcapsularhematoma (SCH) has also been reported as a rare complication of EPN, althoughthere have been no reports to date of this occurring prior to the presentation of EPN. We report a case of EPN that initially presented as spontaneous SCH. The patientwas admitted for left flank pain, and initial computed tomography revealed SCHwithout any air shadows. Laboratory findings and clinical symptoms suggested thepresence of urinary tract infection and the patient was started on antibiotics. Feverdeveloped 24 hours after admission. On follow-up computed tomography 7 dayslater, EPN was newly observed, and a percutaneous drain was inserted. Blood, urine,and drainage fluid cultures all revealed growth of extended-spectrum β-lactamasenegativeEscherichia coli.
