양정영,이재만 문화관광연구학회 2003 문화관광연구 Vol.5 No.2

Traditional folk village has a great significance because it possesses cultural and touristic resources. However for its utilization as touristic resources existence of considerable obstacles must be recognized. What is most important for traditional cultural experience of the region is service to the visitors and attraction luring their re-visitation but currently general attitude is viewing the place merely as an object for sightseeing and such mentality should be transformed. At this juncture what is urgently demanded is transformation of residents’ mentality toward tourists. It is necessary to instill impression on noble style of traditional culture to visitors, providing allurement for revisiting and opportunity for tourists to experience traditional houses personally as touristic product. What is truly required for publicizing Andong is developing traditional touristic products by grafting concept of traditional cultural tourism to the place so that tourists can experience the heritage of traditional folk village and open their eyes to the charm of our unique culture.

The genus Nola (Nolidae, Nolinae) was established by Leach (1815), with the Noctua palliola Denis & Schiffermüller, 1775 (a junior subjective synonym of Phalaena cucullatella Linnaeus, 1758) from Vienna, Austria. Nola comprises over 200 species: Africa and western Palearctic approximately described 100 speices (Hacker et al., 2012); Oriental and Eastern Palearctic regions have over 100 species (László et al., 2010; Sasaki et al., 2011; Kononenko and Pinratana, 2013). Two species of the genus Nola Leach; Nola euryzonata (Hampson, 1900) and Nola lucidalis (Walker, 1865), reported for the first time in Laos. Illustrations of adults and genitalia of all the examined species are provided.

도심지에서 전파경로손실과 지연분산 분석

김재홍,양두영 濟州大學校工科大學産業技術硏究所 1997 尖端技術硏究所論文集 Vol.8 No.1

In this paper, the basic structure to design the cell of PCS on cross-road of urban is analyzed and the propagation model about ultra high-frequency in out-of-sight region is proposed. It is based on image-theory and ray-tracing theory included GTD theory. In order to get the propagation model on a cross-road of urban and analyse the propagation path, the diffraction-coefficient was found by the variable factor of road from transmitting point to receiving point. Finally, to apply at actural environment, we compared the field strength of geometric-optics wave with edge-diffraction wave according to change of the cross-angle and width of cross-road. Also, a time-delay-spread by the change of road factor is proposed and analyzed.

Nowadays there are going to be performed various researches about the operation and management of container terminals. By these researches, problems that arise in operation of container terminals are examined and solved. However the analysis of a port loading equipments actually wastes many time and much money. In these cases, the simulator is the most efficient means among related researches. Therefore this paper studied on a simulator for intelligent port handing equipments. The simulator divided loading courses into five steps and each step made in a module. The virtual port has many 3D objects and objects move each other independently. In this environment, the more 3D objects have, the more the simulator slows by dropping FPS. This problem is solved by the maintenance technique of many objects. Because It took many objects of a container box and guaranteed better FPS.

The advent of the era of ubiquitous computing is attempting to change toward u-Campus. u-Campus requires various ubiquitous computing and network technologies. In this paper, we propose a new facility management service that uses RFID system instead id bar code system. This system can provide the information of facilities by means of radio recognition in real-time, and can support the function of security by carrying in or carrying out management. Using the proposed service in this paper, we expect to able to reduce the manpower, the time, the cost as compared with the existing system.

Ⅲ-Ⅴ족 반도체의 연구 : GaAs의 합성, 단결성 및 특성 Crystal Growth and Characterization of GaAs

이형재,김영기,신영진,박해용,정양준,최춘태,김병호,김진성 全北大學校 基礎科學硏究所 1982 基礎科學 Vol.5 No.1

Temperature of 618 and 1250℃ at As and Ga sities respectively in the horizontal Bridgman furnace and growht speed of 0.7cm/h were found to be optimal for the production of single crystalline GaAs. Self-seeded and unintentionally doped GaAs crystals showd n-type characteristics with Hall mobillity of ∼0.75㎡/V-sec and carrier density of ∼10^19 m^-3 when the mesurements were made right after the growth. About three month later it was found that the same samples were converted to p-type GaAs. The analysis on the p-type sample showed that impurity scattering is dominant at around room temperature and thus the measured Hall mobility was 0.0065㎡/V-sec at 300K. 7.4±0.6 eV was obtained for acoustic deformation potential in the heavy hole band by fitting the theoretical conductivity and Hall coefficient to the corresponding experimental data. The value is very much higher than the theoretically estimated value, 3.6eV. The carrier density variation with temperature obtained from the present analysis gave 0.38 and 0.17 eV respectively for the activation energies of donor and acceptor.

골부초와 자갈대에 의한 고랭지 감자재배지 토양보전 효과

박철수,정영상,주진호,이원정,양재의 한국환경농학회 2005 한국환경농학회지 Vol.24 No.1

강원도 고령지 지역의 밭은 경사지에 발달한 곳이 많아서 강우에 의한 유거수와 토양의 유실이 많이 일어나게 된다. 일부 지역에서는 석비레를 이용하여 농업을 하고 있어 강우침식을 쉽게 받을 수 있다. 이러한 농경지 밭에 쉽게 적용하여 토양유실을 저감시킬 수 있도록 하기 위해 농경지 인근에서 쉽게 구할 수 있는 잡초와 토양침식 후 표면에 남은 자갈을 이용하여 골에 일정 간격으로 두어 그 효과를 살펴보았다. 토양 유실량은 식양토이면서 13%의 경사를 가진 포장에서는 사경과 등고선 경작만으로도 토양 유실량을 현저히 줄일 수 있는 것으로 나타났고, 경사가 23%,인 석비레 사양토 포장에서는 토양 유실이 심하게 발생하는 것으로 나타났다. 부초와 자갈을 최소로 이용하는 골최소부초와 골자갈대를 시험구에 처리함으로써 처리하지 않은 구에 비해 횡계와 용산 포장에서 45% 이상의 토양 유실 저감 효과와 유거수 발생 또한 저감시킬 수 있는 것으로 나타났으나, 사양토인 석비레 성토 지역의 경우는 토양 유실량이 보전처리구에서 61 Mg/ha 이상이 발생하여 골최소부초와 골자갈대를 3 m 간격으로 처리 하여서는 그 효과를 허용 토양 유실량인 11 Mg/ha 이하로 낮출 수 없는 것으로 평가되어 단일한 방법으로는 토양보전에 부족할 것으로 평가되었다. To develop proper soil management practices for reducing soil erosion, experiments were carried out by using lysimeters in Pyeongchang highland, Korea. Lysimeters installed at Hoenggye had 13% slope, 15 m slope length and 3 m width. Lysimeters with 23% slope, 15 m slope length and 5 m width were also installed at Yongsan. Soil textures in Hoenggye and Yongsan lysimeter plots were silty clay loam and sandy loam, respectively. In the lysimeters potato was cultivated, and slant furrow culture and contour culture were applied. Up-down furrow and continuous fallow lysimeter was included in the experiments as a control plot. For the slant furrow and contour culture methods, minimum furrow mulching and gravel barrier were placed at each end of the furrows in the lysimeters from April to October in 2000 and 2001 to prevent soil and nutrient losses. In Heonggye, in two years experiments, average soil loss of 17 Mg/ha was found in the up-down and continuous fallow lysimeter and 2.6 Mg/ha from furrow minimum straw and slant furrow treatment, and 1.8 Mg/ha from slant furrow and gravel bag treatment. In the contour culture, the soil losses were further reduced. In Yongsan, soil loss in the slant furrow culture without any protection treatment was 167 Mg/ha, and the soil loss was reduce to 61 and 86 Mg/ha with minimum straw and gravel bag treatments, respectively. The soil loss could be reduced more than 45% by furrow minimum straw and gravel barrier. The furrow minimum straw or gravel bag barrier successfully reduced soil loss in clay loam soil in Heonggye, but still the treatments were not enough to reduce soil loss in saprolite piled sandy loam soil in Yongsan.
