The series of forest Fires in Kangwon Province in April, 2000, were one of the mast serious ones in the Kang-won Province in recent years. The fire damaged areas are extensive and this paper investigates the utility of the satellite image data, particularly the RADARSAT SAR data. One of the main objectives of this study included evaluation of potential usefulness of the C-band RADARSAT data in the detection of forest fires in mountainous areas. Among several fire damaged sites, the area near Samchuk (city) was selected as the main study area and mufti-temporal RADARSAT(raw) data were acquired and the processed results were comparatively investigated with the IRS-1c data acquired shortly after the fire. To identify the burnt area from the undamaged background in the optical imagery, supervised classification and NDVI processing were carried out and tested with the IRS-1C data. For this experiment, several sets of raw RADARSAT standard and Fine mode (S4, F3, ascending orbit) data were processed and the final image was formed. In addition to the final image, sigma nought (σ°) was catnputed and compared for the burnt area against the undamaged areas. Because of the steep slopes in the study area and subsequent deviation from the flat surface scattering models, the fire scars in the sigma nought (σ°) image were not apparent. However, fire scars are slightly detected in the difference and ratio images obtained from the signal intensity data acquired at different dates (bath before and after fire). Texture analysis of the image data including the burnt areas were carried out using the Multiplicative Markov Random-Field (MMRF) algorithm. The detection of the fire damaged area from both standard mode and fine mode RADARSAT was not as straightforward as in optical data. However, Previous studies with ERS-1 S_AR and RADARSAT data in Indonesia and in the North American Plains indicate that C-band SAR data provide us with an effective tool for studying the forest fire damages. However, the application of C-band SAR data to the analysis of the forest fire areas requires careful processing of the data with realistic scattering models.

최준서(Choi, Joon-Seo),배재성(Bae, Jay-Song),강영희(Kang, Young-Hee) 한국체육과학회 2015 한국체육과학회지 Vol.24 No.6

The purpose of this study is to analyse the strategy of KBS World Cup Broadcasting in 2014 pertaining to its commentator and sportscaster in leading its broadcasting to the best program with the highest audience ratings. It is also assessed as to how KBS World Cup commentator and sportscaster was selected and why they could have a magnetism to successfully attract the TV viewers In the run up to the 2014 World Cup, KBS have employed a new commentator with expertise and experience as former South Korean football international and choose a relatively young sportscaster who could fit in well with the commentator. This strategy carried forward by KBS struck a chord with the TV viewers: Young-Pyo Lee, the KBS commentator was praised for his expertise and ability to predict the outcomes of important World Cup matches, a style that was in stark contrast with more frivolous and entertaining broadcasting of MBC. Also KBS could put SBS with the established commentator into the shade by virtue of Lee’s exceptional capabilities in analysing World Cup games. It is safe to say that the success of KBS World Cup broadcasting greatly relied on the ability of its commentator as a football analyst. It is a reassurance that the expertise of commentator is the most important factors in dictating ratings of the World Cup broadcasting.

바이오매스에서 유래된 2,5-dihydroxymethylfuran(DHMF)을 KMnO4 산화반응으로 furan-2,5- dicarboxylic acid(FDCA)를 합성하였다. 합성한 FDCA와 다이올류를 에스테르화 반응과 축중합 반응을 진행시 켜 폴리에스터를 중합하였다. 폴리에스터는 NMR을 통해 조성을 분석하였고 DSC와 TGA를 통해 열적특성을 분 석하였다. 합성된 폴리에스터의 고유점도는 0.78∼1.2 dL/g으로 상용화된 poly(ethylene terephthalate)(PET) 와 비슷하였다. 다이올의 길이가 증가할수록 Young`s modulus와 strength는 낮아지고 elongation-to-break는 높아지는 경향을 확인하였다. 합성한 poly(ethylene furandicarboxylate)(PEF)의 Young`s modulus는 3551 MPa, strength는 103 MPa로 상용화된 PET와 비슷하였다. Furan-2,5-dicarboxylic acid (FDCA) was synthesized by KMnO4 oxidation of 2,5-dihydroxymethylfuran( DHMF) derived from biomass. Polyesters were synthesized by esterification and polycondensation of FDCA with various diols(ethane-1,2-diol, propane-1,3-diol, butane-1,4-diol, hexane- 1,6-diol, decane-1,10-diol). The composition of polyesters was characterized by using 1H NMR. Thermal properties of the polyesters were characterized by DSC and TGA. Intrinsic viscosities(IV) of the polyesters were measured to be 0.78∼1.2 dL/g comparable with IV of commercial poly(ethylene terephthalate)(PET). As the chain lengths of diols increased, Young`s modulus and strength decreased and elongation-to-break generally increased. Young`s modulus and strength of the polyesters were measured to be 3551 MPa and 103 MPa, respectively, comparable with commercial PET.

Steroid cell tumor is a rare ovarian sex cord-stromal tumor which accounts for 0.1% of all ovarian tumors. Until now, only 4 cases have been reported in domestic literatures. Steroid cell tumor often secrets testosterone and presents virilization in adult women or precocious puberty in children. Treatment is often performed by surgical removal, adjuvant chemotherapy and radiation, but completely accepted treatment was not existed. We experienced a case of steroid cell tumor, which was manifested by typical virilization in a 43-year old patient, who was previously performed hysterectomy and unilateral oophorectomy. So, we present with a brief review of the literatures.

77K와 상온에서 CO(NH₂)₂분말 시료의 ??N Pulsed NQR실험을 하여 위와 아래 공명 진동수, 핵 사중극 결합상수, 비대칭 인자, 스핀-스핀 완화시간, 결정 격자 진동에서의 평균 비틀림 진동수, 진동자의 관성 모먼트 등을 구하였다. 공명 진동수의 온도 의존성은 전형적인 Bayer이론의 격자 진동에 의한 주파수 변화를 보였다. Bayer-Kushida이론의 고온근사식을 실험값에 적용하여 OK에서 공명 진동수 ν??와 ν??를 구했으며, 77K와 상온에서의 스핀-스핀 완화시간 T₂를 관측했다. 상온에서 T₂의 감소는 결정 내의 reorientation motion과 관련이 있을 것으로 보인다. Upper and lower resonance frequencies, nuclear quadrupole coupling constants, asymmetry parameters, spin-spin relaxation time, average torsional frequency in the crystal lattice motion and moment of inertia in the oscillator are found for CO(NH₂)₂powder sample by using ??N Pulsed NQR(Nuclear Quadrupole Resonance) technique at 77K and room temperature. Temperature dependence of resonance frequencies showed frequency variation in agreement with the typical Bayer's theory in lattice motion. Resonance frequencies ν?? and ν?? at OK were obtained by fitting the high temperature approximation of Bayer-Kushida theory to the experimental data and spin-spin relaxation time (T₂) was observed at 77K and room temperature. Decrease of T₂at room temperature was explained by the effect of reorientational motion in the crystal lattice.

슬관절은 지속적인 압력을 받거나 충격때문에 동작범위의 한계에 이를 때 손상받기 쉽다. 반월판 파열 환자는 일상생활에 지장을 주는 동통, 정복되지 않는 잠김, locking이나 giving way가 자주 일어나는 경우, 지속적인 신전제한이 있을 때 수술의 적응증이 된다. 반월판 파열 환자의 재활에 있어서 관건은 대퇴사두근의 근력과 ROM의 회복이다. 팔체질침 시술후 반월판 부분절제술을 시행한 환자가 동통의 강도와 동통 재발의 감소, ROM의 개선, 전반적 상태면에서 체침이나 MPS 시술 때보다 더 나은 경과를 얻었다. Knee joints are apt to be injured when they are over the limit of ROM by continuous pressure or impact. The patient of meniscus tear has to be operated in case that he has the symptom of knee pain obstructive to daily life, unreducable locking, frequent locking or giving way, continuous extention limit. In the rehabilitation of the patient of meniscus tear, the key is the progress of musculi quadratus femori's power and ROM. After 8 constitutional acupucture therapies, partial menisectomy patient has the better process about decrease of pain intensity and relapsing pain frequence, development of ROM, general condition more than general acupucture or MPS medical treatment.

An automatic, programmable facial expression construction method has been proposed in terms of virtual reality implementation application. Several patterns of expressions were stduied to reconstruct those patterns to generalize with another object image experimentally. The results show that any kind of object actions, especially, facial expression, in a range of a certain background could be reconstructed by the pattern manipulation automatically. Smile expression was experimented in this paper, however, cry, angry or any other expression would be derived by using proposed procedure.

n-부틸알코올-플라즈마중합박막을 폴리에스테르 표면위에 생성시켜 표면의 특성을 개질 하였다. 폴리에스테르의 표면은 생성된 박막 내의 친수성기에 의해 친수성으로 개질되었으며 친수성의 정도는 박막내의 산소함량과 밀접한 관계가 있었다. 한편 박막은 발수 및 방오의 효과를 갖는 보호성 차단막으로서의 특성도 나타내었다. We have modified surface property of polyster by deposition of the n-butyl alcohol plasma polymerized thin film. The surface property of polyester was modified to hydrophilic and the hydrophylicity depended closely on the oxygen content of the thin films. The thin film has also protactive barrier property, water repellency, and stain proof property.

Generally, a street-inlet in road facility is aimed to exclude rainfall and filth from sewer system. In order to solve some problems in current street inlet facilities, some revised inlet systems have been suggested. Those revised facilities can also solve an environmental problem like a bad smell emitting from the worn facility and solve civil petitions due to its safety and poor quality of passing rainfall. In this study, the existing rainfall exclusion facility was investigated including foreign countries and a developed street inlet model was represented through estimating of their structures, characteristics and costs. It also be analyzed that the existing problems can be solved by a trial construction and the developed model was compared with existing models by focusing on constructability and maintenance capacity.
