H-S Lee, Y-S Lee, J-C Byun. The effects of EMG activity and blood fatigue makers on balance taping treatment by exercise type. Korean Journal of Sport Biomechanics, Vol. 14, No. 3, pp. 271-284, 2004. The purpose of this study was to analyse the EMG activity of selected muscles with balance taping treatment and blood fatigue makers which accumulated during exercise of progressive maximal intensity. Ten male college students who did not experience any cardiovascular and musculo-skeletal disease were participated in this study. Balance taping were applied to rectus femoris, vastus medialis, vastus lateralis, biceps femoris, semitendinous, semimembranous, and around knee joint. Isokinetic knee joint flexion/extension force, EMG activity, lactate and ammonia as blood fatigue makers during progressive maximal intensity exercise were measured for with/without applying balance taping. The results indicated that although flexion force of total work at 60˚/sec with taping was increased applied taping did not affect to the aerobic exercise ability parameters. Lactate level as blood fatigue makers during progressive maximal intensity exercise after taping was decreased but the ammonia level did not change with same treatment. In isokinetic knee joint test at the angular velocity of 60˚/sec, 180˚/sec, and 240˚//sec the taping treatment did not affect to any selected muscle EMG activities except maximal EMG of vastus lateralis at 240˚/sec.

연구배경: 동일한 환자를 대상으로 조혈모세포이식 전 일반 병실에서의 관해유도 항암제치료 및 강화요법으로 인한 호중구감소 기간의 감염양상과 고용량 항암제치료 후 무균실에서의 조혈모세포이식 시 호중구감소 기간의 감염양상을 중심정맥관 관련 패혈증을 중심으로 비교 연구함으로써 효율적인 감염관리지침을 마련하고자 하였다. 대상 및 방법: 1999년 1월부터 2001년 7월까지 2년 7개월간 동아대학교병원 일반병실에서 악성혈액질환으로 항암제 치료를 받다가 조혈모세포이식을 시행받았던 22명을 대상으로 중심정맥관 관련 패혈증의 형태를 비교분석하였다. 결과: 대상 환자들의 일반병실과 무균실에서의 입원기간은 각각 32±13일, 33±19일, 호중구 감소기간은 15±12일, 17±18일, 호중구 감소기간의 발열 횟수는 14회, 14회로서 입원병실의 종류에 따른 차이는 없었다. 환자들의 중심정맥관 사용일수는 일반병실에서 29일(7~545일), 무균실에서 100.5일(25~606일)이었으며, 총 사용일수는 각각 1,515일, 3,250일로서 무균실에서의 중심정맥관 사용일수가 의미 있게 길었다(P=0.001). 중심정맥관 사용 일수에 대한 감염률은 각각 5.28/1,000일, 3.08/1,000일로서 일반병실에서 그 빈도가 높았으나 통계적 유의성은 보이지 않았다(P=0.141). 결론: 중심정맥관 삽입 후 일반병실에서 항암제 치료를 받던 환자가 조혈모세포이식을 위하여 무균실에 입원하는 경우, 중심정맥관을 교체하는 것이 감염관리를 위하여 바람직할 것으로 생각된다. Background: We compared the incidence of central venous catheter (CVC) related septicemia during neutropenic period in the same patient, which developed following chemotherapy for remission induction and consolidation, or hematopoietic stem cell transplantation (HSCT). Methods: We retrospectively reviewed the medical records and laboratory data of 22 patients with hematologic malignancies who received anticancer chemotherapy followed by HSCT at Dong-A University Hospital between January, 1999 and July, 2001. We investigated the duration of hospitalization, duration of neutropenic period, duration of catheterization, microbiologically documented organisms and incidence of CVC related septicemia. Results: The data in general ward (before HSCT) and laminar air flow room (after HSCT) were as follows: duration of hospitalization was 32±13 days and 33±19 days, duration of neutropenic period was 15±12 days and 17±18 days, median duration of catheterization was 29 days (7~545 days) and 100.5 days (25~606 days) (P=0.001), and incidence of CVC related septicemia was 5.28/1000 days and 3.08/1000 days, respectively. In the CVC related septicemia, the most common etiologic organism was coagulase negative staphylococcus. Conclusion: We suggest that the exchange of CVC before admission to laminar air flow room could decrease the incidence of CVC related septicemia in HSCT recipients.

본 연구에서는 새만금과 같은 간척지를 활용하여 대규모 첨단온실단지를 조성하는 경우 간척지의 환경적 특수성 중 높은 풍속에 따른 유리 단열재의 에너지 효율을 평가하였다. 현장에서 주로 사용되는 온실 단열재 중 4가지에 대한 평가 결과, 최대 37.4%의 에너지 차이를 보여, 온실 피복재의 선정이 중요함을 제시하였다. 이를 바탕으로 일반적인 내륙에서의 온실을 설계하는 것과 달리, 간척지에서는 내재해성 온실규격을 따라 시설을 설계하여야 하며, 에너지 소비량은 높아진 풍속과 재질을 고려하여 산정되어야 한다. 본 연구의 결과는 에너지 효율성을 온실 피복재의 종류와 풍속에 따라서 제시하고 있으며, 이는 대규모 첨단온실 조성 시 에너지 소비량을 예측하고, 이를 바탕으로 신재생에너지원을 포함하는 에너지 설계에 활용될 수 있다. The external weather conditions including temperature and wind speed in the Saemangeum reclaimed land is different from that of the inland, affecting the internal environment of the greenhouse. Therefore, it is important to select an appropriate covering material considering the insulation effect according to the type and characteristics of the covering material considering the weather condition in the Saemangeum reclaimed land. A hexahedral insulation chamber was designed to evaluate the insulation efficiency of each glass-clad material in the outside weather condition in reclaimed land. In order to evaluate the insulation effect of each covering material, a radiator was installed and real-time power consumption was monitored. 16-mm PC (polycarbonate), 16-mm PMMA (polymethyl methacrylate), 4-mm greenhouse glass, and 16-mm double-layered glass were used as the covering materials of the chamber. In order to understand the effect of the external wind directions, the windward and downwind insulation properties were evaluated. As a result of comparing the thermal insulation effect of each greenhouse cover material to single-layer glass, the thermal insulation effect of double-layer glass was 16.9% higher, while PMMA and PC were 62.5% and 131.2% higher respectively. On average the wind speed on the windward side was 53.1% higher than that on the lee-wind side, and the temperature difference between the inside and outside of the chamber at the wind ward side was found to be 52.0% larger than that on the lee ward side. During the experiment period, the overall heating operation time for PC was 39.2% lower compared to other insulation materials. Showing highest energy efficiency, and compared to PC, single-layer glass power consumption was 37.4% higher.

To identify aberrantly hypermethylated DNA in lung cancer cells we established a genome-wide analysis for hypermethylation sites, namely Methyl DNA Isolation and Amplification (MeDIA) coupled-CpG microarray analysis. In the comprehensive methyaltion profiling analysis between human lung cancer, A549 cells and normal NHBE cells, we observed that several clusters of genes show a significant level of aberrancy in CpG island methylation pattern in cancer cells compared to normal cells. We further identified PCDHGA12 gene as a new marker of non-invasive diagnostics for lung cancer based on followings. 1) Transcription of PCDHGA12 gene is reactivated after treatment of A549 cells with demethylating agent. 2) Bisulfide clonal-sequencing reveals that CpG island of PCDHGA12 shows a distinctive differential methylation between two cell lines. 3) Pyrosequencing-based quantitative methylation assay for such region in tumor and non-tumorous tissues from lung cancer patients shows aberrant hypermethylation in 37 (92%) of the 40 tumor tissues. In clinical validation by pyrosequencingin induced-sputum of lung cancer patients (n=87) and healthy controls (n=51), we observed aberrant hypermethylation incident at significantly elevated level in samples derived from lung cancer patients. According to the optimal threshold calculated by ROC curve analysis, sensitivity and specificity of PCDHGA12 was 86.2% and 82.4%, respectively. PCDHGA12 methylation status could be a potential methylation biomarker alone or combined with others for the screen and the detection of relapse of lung cancer.

This paper proposed an extracting algorithm of human facial components for the recognition of facial expressions. First face image is acquired using the Haar-like feature mask from an input image. The face image is divided into two images. One is the upper image including eye and eyebrow. The other is the lower image including mouth and jaw. The extraction of facial components, such as eye and mouth, begins getting eye image and mouth image. Then eigenfaces are produced by the PCA training process with learning images. An eigeneye and an eigenmouth are produced from eigenfaces. Result eye image is obtained by template matching the upper image with the eigeneye, and the mouth image is obtained by template matching the lower image with the eigenmouth. The simulation results show that the proposed method has superior extraction ratio than previous method.

Objectives : The individual's ability to recognize and describe emotion in self and others is an important concept of many psychiatric disorders. The purpose of this study was to investigate emotional awareness deficits in patients with alcohol dependence. Methods : 55 male inpatients with alcohol dependence and 28 male normal controls were evaluated by the Korean version of the Levels of Emotional Awareness Scale (LEAS-K), the Korean version of the 20-item Toronto Alexithymia Scale (TAS-20K), the Openness Experience Inventory (OEI) and the Beck Depression Inventory (BDI). The LEAS-K. is an objective measure to assess the ability to be aware of one's own or another's emotions and the TAS-20 is the most widely used subjective measure of alexithymia. Scores of these scales were compared between two groups using ANCOVA controlling age and BDI scores. Results : The LEAS-K scores were significantly lower in alcohol-dependent patients than normal controls. The TAS-20K total scores, factor 1 (Difficulty to IdentiIying Feeling, DIF) and factor 3 (Extemally Oriented Thinking, EOT) were Signifi-cantly higher in alcohol-dependent patients than normal controls. In contrast to the LEAS-K, the TAS-20K scores correlated significantly with the BDI scores. Conclusion : Emotional awareness is impaired in alcohol-dependent patients and it may not be related with depressive mood. Additional studies are needed to explore the significance of alexithymia, especially impaired emotional awareness, and its relationship to depressive mood in patients with alcohol dependence.
