Objective : To set up the concept and the category of the medical humanities in Korean medicine education through researching and analysing the curriculum of 12 colleges and school of Korean medicine (KM) in Korea. Methods : We collected self-evaluation reports from 12 KM institutions, and analyzed subjects regarding medical humanities and social medicine. The subjects' relevance with medical humanities was verified using the learning objectives of KOMEEI(Korea Oriental Medicine Education and Evaluation Institute). The number of relevant subjects, the credits and educational hours, and the time of opening, etc. were analysed. Results : 12 KM institutions provide 44 subjects as medical humanities and social medicine related subjects. Among them, 17 subjects were corresponded to the actual learning objective of medical humanities. These subjects account for an average of 7% in total curriculum. Most of the subjects are required courses for premedical students and the fourth year students of medical school. Conclusions : This paper suggests the public discussion on the learning objective and the categories of the medical humanities education in KM institutions. Further studies on developing the educational contents and evaluation tools are also needed to produce good doctors with ability and personality.

This paper defined the concept of unsold land and diagnosed the cause of unsold land of LH business site. The results are showing as follows. First, unsold land is defined as land could not be sold until the completion of the project, and plan to sell the unsold land can be changed partially. Second, the status of unsold land in the 226 project sites were analyzed. $146km^2$ area corresponding to 74.8% of the total capital area($195km^2$) are unsold. By purpose, co-residential($38km^2$), industry($21km^2$), exclusive residential($16.4km^2$), commercial business($12.5km^2$), education($10.2km^2$) was larger in order. Third, value enhancement target project sites were selected and its symptoms and the cause of unsold land were analyzed. For the project site over average unsold rate, 6 sites located in province and 2 sites located in capital region were selected through collecting the practitioners and expert opinion. These 8 sites are characterized that sale of land for medium and large co-residential, urban support facilities, block-shaped house and attached house was inactive. Also, these sites commonly experienced economic fluctuations, changes in market demand, supply and demand mismatch, inflexible planning standards.

In this paper, we propose a wireless video transmission scheme, providing medium and long range communication in the 2.4GHz band with beamforming. With this scheme, it is shown that the transmission rate of 32Mbps and received signal power of -77dBm is achieved with 4 antennas of 5dBi and 16dBm transmit power at each antenna connection for the distance of 3.6km. The scheme also provides transmission distance of 20km for 10~12Mbps with the 4 omni-directional antennas of 5dBi.

We present $^{12}CO$ J = 2-1 line observations of G54.1+0.3, a composite supernova remnant with a mid-infrared (MIR) loop surrounding the central pulsar wind nebula (PWN). We map an area of $12^{\prime}{\times}9^{\prime}$ around the PWN and its associated MIR loop. We confirm two velocity components that have been proposed to be possibly interacting with the PWN/MIR-loop; the +53 km $s^{-1}$ cloud, which appears in contact with the eastern boundary of the PWN and the +23 km $s^{-1}$ cloud, which has CO emission coincident with the MIR loop. However, we have not found a direct evidence for the interaction in either of these clouds. Instead, we detected an 5'-long arc-like cloud at +15-+23 km $s^{-1}$ with a systematic velocity gradient of ~3 km $s^{-1}$ $arcmin^{-1}$ and broad-line emitting CO gas with widths (FWHM) of ${\leq}7km\;s^{-1}$ in the western interior of the supernova remnant. We discuss their association with the supernova remnant.

In order to develop a overhead catenary system for the maximum speed of 400 km/h on Honam high-speed line, increasing tension of contact wire, changing dropper distributions, reducing a hard point and etc. should be considered. And it is also essential to develop core components taking account of the increased tension. Therefore we developed a new steady arm for the max. speed of 400 km/h in this study. FEM (Finite Elements Method) analysis was performed to ensure the strength of the arm. An oval shape was applied to the arm, so that 25 % of strength was increased and 9 % of weight was decreased. And a type test according to the code KRSA-3012 was performed to ensure the performance. Fatigue test in KRRI (Korea Railroad Research Institute)'s test-bed was also performed to evaluate its performance. Some section of the Honam High-speed line was constructed with the developed steady arm.

The velocity structure beneath the CHNB broadband station is determined by receiver function analysis using by from teleseismic P waveforms. The detailed broadband receiver functions are obtained by stacking method for source-equalized vertical, radial and tangential components of teleseismic P waveforms. A time domain inversion uses the stacked radial receiver function to determine vertical P wave velocity structure beneath the station. The crustal velocity structures beneath the stations are estimated using the receiver function inversion method in the case at the crustal model parameterized by many thin, flat-tying, homogeneous layers. The result of crust at model inversion shows the crustal velocity structure beneath the CHNB station varies smoothly with increasing depth, and there are six discontinuity around 2.5km, 6.25km, 12.5km, 22.5km and 27.5km depth, with Moho discontinuity at about 32.5km depth.

한전의 가공 송전선로는 2010년 기준으로 약 12,990km(765 kV 송전선로 354 km, 345 kV 송전선로 약 3,868 km, 154 kV 송전선로 8,173 km, 66 kV 송전선로 : 약 595 km)가 설치되어 운전되고 있다. 이러한 송전선로는 평지, 구릉, 산악지 등에 설치됨으로써 자연환경에 크게 영향을 받는다. 특히 전 세계적으로 낙뢰에 의한 송전선로의 트립 고장이 전체 고장의 약 60%를 점유하는 것으로 보고되고 있으며, 낙뢰에 의한 고장을 최소화하기 위한 내뢰 설계를 시행하고 있다. 한전에서도 전압별 계통의 신뢰도와 경제성을 고려하여 765 kV 송전선로의 목표 사고율은 0.35[건/100 km 년], 345 kV 송전선로의 경우는 1.0[건/100 km.년], 154 kV 송전선로의 경우는 2.0[건/100 km 년] 이하의 목표 사고율을 설정하여 설계 운영하고 있다. 그러나 2000년 이후 낙뢰발생 빈도가 증가하고 있으며, 낙뢰에 의한 고장 점유율도 약 75%로서 고품질 전력공급을 위한 내뢰 대책 수립의 검토가 요구되고 있다.

Attenuation losses and repeater spans of single-mode optical fibers installed in the long hual optical transmission line were measured and analyzed. The average loss including splicing points was appeared to be 0.55 0.05dB/km and 0.59 0.01dB/km at 1300nm and 1550nm, respectively, and showed lager value at 1550nm window, The cause of loss increase at 1550nm range from the OTDR measurement was due to the inappropriate treatment of extra length of fiber at the splicing points. And average repeater span of domestic long haul line was 24 7km and 90% of total sampled repeater spans was within 31 km.
