Purpose: The purpose of the study was to forecast manpower by building the nursing manpower-staffing model(surgical-medical nursing unite). Method: The system dynamics approach was adapted to build a simulation model for calculating medical-surgical nursing manpower-staffing. The model was built up on Venism 5.0b DSS. Result: The results in the basic circumstance are in following. The level of nursing service quality, patientsatisfaction, and nurse job satisfaction maintains higher at medical-surgical nursing unit of the tertiary hospitals with the ratio of bed to nurse 2.5:1-3.0:1 than at any other situations. The level of nursing service quality, patient satisfaction, and nurse job satisfaction maintains higher at madical nursing unit of the secontary hospotals with the ratio of bed to nurse 3.0:1 and at surgical nursing unit of the secondary hospitals with the ratio of bed to nurse 3.0:1-3.5:1 than at any other situations in the fundamental from. The results in the simulation circumstance are in following, As author raises the operating rate of bed into 95-100%, and cut skilled nursing staff down, the level of nursing-service quality, patient satisfaction, and nurse job satisfaction drops slightly. Conclusion: In terms of economic efficiency on tertiary hospotals, the ratio of bed to nurse for the best reasonable medical-surgical nursing manpower-staffing is 3.0:1. In terms of economic efficiency on secondary hospitals, the ratio of bed to nurse for the best reasonable medical nursing manpower-staffing is 3.0:1 and surgical nursing manpower-staffing is 3.5:1

<P><B>Abstract</B></P><P>Cinnamaldehyde from the bark of <I>Cinnamomum cassia</I> has been reported to have antitumor activity mediated by the inhibition of farnesyl transferase. We assessed in vivo the chemo-preventive effect of cinnamaldehydes on H-<I>ras</I>12V-induced hepatocellular carcinoma formation. A mouse model of hepatocellular carcinoma was established by using the transgene of mutated H-<I>ras</I>12V under the regulation of albumin enhancer/promoter. When treated with cinnamaldehyde for 10 weeks, hepatic tumor development was delayed with 2′-benzoyloxycinnamaldehyde (BCA) compared with control hepatocellular carcinoma formation. The effect of 2′-hydroxycinnamaldehyde (HCA) was comparable. The number of lesions and the size of each lesion were significantly reduced by BCA. Cell proliferation in the lesion was detected by incorporation of 5-bromo-2′-deoxyuridine (BrdU). BCA increased the number of splenocytes, concanavalin A-stimulated splenocyte proliferation and the infiltration of lymphocytes into liver. Data suggest that the delayed hepatic tumor development observed with BCA could be mediated by a long-term immunostimulating effect on T cells.</P>
Peak-to-average power control for multiple-antenna HIPERLAN/2 and IEEE802.11a systems

A combination of multi-input multi-output (MIMO) signal processing with orthogonal frequency division multiplexing (OFDM) is regarded as a promising solution for enhancing the performance of next generation wireless local area network (WLAN) systems. This paper evaluates the peak-to-average power ratio (PAR) performance in a MIMO OFDM-based WLAN system using a space-time block code (STBC). The investigated PAR control schemes, which are originally based on the selective mapping (SLM) and partial transmit sequence (PTS) approaches, select the transmitted sequence with the lowest average PAR over all transmit antennas and retrieve the side information (SI) very accurately at the expense of a slight degradation of the PAR performance. The low probability of false SI can improve the overall detection performance of the MIMO-WLAN system encountered with erroneous SI compared to the ordinary SLM and PTS approaches, respectively.

<P>The complete genome sequence of porcine enterovirus B (PEV-B) from a Korean isolate was analyzed. The genome size was 7,393 bp. Previously, full genome sequences of PEV-B had been reported from the United Kingdom, Hungary, and China. The Korean PEV-B isolate presented polyprotein gene nucleotide sequence similarities of 77.9, 73.7, 78.9, and 80.3%, respectively, to PEV-B UKG/410/73, LP54, PEV15, and Chinese strains (Ch-ah-f1).</P>

Three solvent systems, chlorobenzene (ink 1), chlorobenzene/o-dichlorobenzene (ink 2) and chlorobenzene/tetrahydronaphthalene (ink 3), were compared as printable inks for the fabrication of polymer light-emitting diodes (PLEDs) using poly[2-methoxy-5-(2-ethylhexyl-oxyl)-1,4-phenylenevinylene (MEH-PPV) as an emissive material and an inkjet printer (Fujifilm Dimatix DMP-2831). Ink 1 clogged the printer's nozzle and gave non-uniform film. Inks 2 and 3 were used to fabricate PLEDs with ITO/PEDOT:PSS/MEH-PPV/LiF/Al configurations. The best performance (turn-on voltage, 3.5 V; luminance efficiency, 0.17 cd/A; luminance, 1,800 cd/m) was obtained when ink 3 was used to form the emissive layer (thickness, 49 nm), attributable to the better morphology and suitable thickness of the MEH-PPV layer.

문영빛(Moon Young Bit):김도기(Kim Do Ki),문영진(Moon Young Jin),권순형(Kwon Soon Hyoung) 학습자중심교과교육학회 2016 학습자중심교과교육연구 Vol.16 No.12
본 연구는 경기교육종단연구 2차년도(2013년) 자료를 활용하여 서술형 평가정책에 대한 교사의 인식이 수업방식을 매개로 학생의 학업성취도에 미치는 영향을 분석하였다. 서술형 평가정책에 대한 교사의 인식 및 수업방식은 교사용 자료를 활용했으며, 학생의 학업성취도는 초등학생의 국어, 영어, 수학 성취도(모두 T점수)를 활용하였다. 3,012개의 학생 자료와 332개의 교사 자료를 활용하여 구조방정식 모형으로 분석을 진행하였다. 본 연구는 주로 2015년 8월부터 11월까지 이루어졌으며, 2016년 9월부터 11월까지 수정·보완하였다. 본 연구의 결과는 다음과 같다. 첫째, 서술형 평가정책에 대한 교사의 인식은 교사의 수업방식에 영향을 준다. 둘째, 교사의 수업 방식 중 교수자 중심 수업은 학생의 학업성취에 유의한 영향을 주고 있었으나, 학습자 중심 수업은 그렇지 않았다. 셋째, 위와 같은 결과에 따라 교사의 수업방식의 매개효과는 교수자 중심 수업에서 확인할 수 있었다. 이와 같은 연구 결과를 바탕으로 제시할 수 있는 정책적 제언은 다음과 같다. 첫째, 정책에 대한 교사들의 인식이 바르게 이루어졌는지를 확인할 필요가 있다. 둘째, 교사의 수업방식이 서술형 평가와 잘 연계되어 있는지 확인할 필요가 있다. 이를 위해서 교육청에서는 교사들의 정책 인식을 제고시킬 수 있도록 정책 안내, 정책 참여, 안정적 정책 운영 등과 같은 다양한 방안들을 마련하여 시도해야 할 것이다. This study analyzed how the teacher s perception about descriptive assessment policy made effects on the academic achievement of students mediated by teaching methods using the second year s teachers and students data of Gyeonggi Education Panel Study. The elementary teachers data was used for the teachers perception and teaching methods and the Korean, English and Math T-scores in the elementary students data were used for the achievement of students. For the analysis, the study model was set up using the structural equation model, and 3,012 students data and 332 class teachers data excepted missing data were analyzed. This study mainly be fulfilled on August to November in 2015, and revised and complemented on September to November in 2016. The results of this study are as follows. First, the teacher s perception effects on teaching methods. Second, in elementary teacher-centered teaching significantly effects on the student s achievement, but learner-centered teaching is no statistically significant. Third, it could be confirmed that how the teacher s perception about descriptive assessment policy made indirect effects on the academic achievement of students mediated by teacher-centered teaching methods. The political suggestions from the results of this study are as follows. First, it could do with confirming the teacher s perception about descriptive assessment policy is correct. Second, it could do with confirming the link between teaching methods and descriptive assessment is well. For these, the education office in-local should prepare various ways as policy guidance, participation and stable policy implementation to enhance the spontaneous behavior of teachers.
