1) Lishu village is located in a riverside of an upper Tu-men river. Since an upper tream of Tu-men river is narrow and easy to pilot a boat, early in the past, it facilitated the form of the village near to the North Korea. 2) As for elevation, it consisted of only doors, but as time goes by, windows were made. So windows and doors were appearing much in the elevation. In 1970s', elevations are constructed in various ways; in 1980, attributed to brick housing, the elevations become much more diverse; from 1990, symmetrical elevation was revealed which consists of one door and two windows in each side of a door after 2000, the structure of the housing restored of 1930s' style which contained one window in Jungji and 1970s' style consisting of 3 windows, moreover, many free-style elevations appeared to be commercial use.

충주지역에서 표고가 다른 9개 지점(계명산 5지점, 남산 4지점)에서 측정한 기온 관측자료를 분석하여 기온이 표고가 높아짐에 따라 일정한 비율로 변화하는 단열조건에 의한 기온체감율을 계산하고, 표고별 후지 품종의 만개기를 추정하였다. 충주 계명산 남서사면에서 측정한 시간별 기온자료를 표고와의 관계로부터 표고가 100 m 상승함에 따라 기온은 0.89$^{\circ}C$의 일정한 비율로 체감하였다. 남산 북서사면에서 측정한 시간별 기온자료와 표고와의 상관으로부터는 0.74$^{\circ}C$/100 m의 비율로 기온이 체감함을 알 수 있었다. 충주지역에서 일평균 기온 5$^{\circ}C$ 이상인 날의 발육속도(DVR)를 계산하여 추정한 만개기와 실제로 조사된 만개기는 서로 일치하는 경향이었으며 표고별로 추정된 충주지역의 사과 만개기는 해발고도 100 m 상승함에 따라 4~5일 늦어졌는데 고도에 따라 4월 25~5월 10일의 범위이었다.

The purpose of this study is to analyze the elevations of standard rural house designs after the 1990's. Various types of analysis were carried out on a total of 18 different sizes and 50 types of designs with p'yong sizes ranging from 12 to 44. The objects of analysis are the various elevations & the roof types that were supplied in the standard rural house design according to each year 1995 (8 sizes 20 types), 1997 (8 sizes 8 types), 1998 (l size 8 types), 2000 (2 sizes 4 types), 2001 (2 sizes 4 types), and 2004 (3 sizes 6 types). Results from the analysis demonstrate that (1) The gable roof has been used as the roofing type for standard rural house design since 1990. However the roof types of the standard rural house design includes only a few different types of gable roofs and roof materials(most roof types use asphalt shingle). (2) While most front elevations have been altered from asymmetrical to symmetrical most rear elevations have evolved from symmetrical to asymmetrical proportions since the 1990's (3) While siding materials and red-brick were most commonly used the main outer-wall materials prior to 2000, environmentally-friendly materials have been used as outer-wall materials since 2000. (4) In terms of the analysis of outer-wall objects before 2000 the walls were even, yet after 2000 these outer-walls evolved to become concave-convex walls. In other words, the evolution of the outer-wall has included a variety of wall types.

The aim of this study was to compare the activity of the upper trapezius (UT) and serratus anterior (SA) and ratio of UT to SA during shoulder elevations. Ten subjects with UT pain (UTP) and 13 subjects without UTP participated in this study. Subjects with a UTP of over five in a pain intensity visual analogue scale (0-10 ㎝) for more than 2 months and latent myofascial trigger points (MTrPs) in the UT muscle were included in the UTP group. Electromyography (EMG) data of UT and SA at 1st and 10th elevations were analyzed. Two-way repeated analyses of variance were used to compare the EMG activity of UT and SA and the ratio of UT to SA during shoulder elevations between groups with and without UTP. There was a significant increase in UT/SA ratio in the group with UTP compared to the group without UTP (p=.01). The activity of UT and SA measured at the 10th elevation was significantly greater than that in the first elevation (p<.05). The activity of SA was significantly greater in the group without UTP than the group with UTP (p=.03). However, there was no significant difference between groups with and without UTP in terms of UT activity (p=.28). These results indicate that UTP may have relevance to the increased muscle activity ratio of UT to SA during shoulder elevations.

Eight drawings of Sukcheon-je-a-do are the architectural drawings of the government offices. These were drawn in the representation of Sabang-jeondo-myobeob. Sabang-jeondo-myobeob is one of Korean traditional drawing type, that is constructed with turned-over elevations drawn on the site plan. The analytic observation viewed in the iconographical diagrams of eight drawings led me following conclusions. First, the most typical expression of Sabang-jeondo-myobeob can be summarized as the combination of three elevations toward the inside and one elevation toward the outside. The former is expression of territoriality, and the latter is expression of the facade. Second, in Sabang-jeondo-myobeob both elevations of crosswise direction and of lengthwise direction are described at the viewpoint of eye level. And they center around the courtyards with intent to describe the relation between buildings and the outdoor space. Third, the facade of pavilions, disposed on the crosswise direction in Sabang-jeondo-myobeob, are described with the both viewpoint of down-view and up-view. It is the expression peculiar to Korean traditional drawings, that describes the depth and richness on the facade of traditional wooden architecture. Fourth, some pavilions and landscapes are described in Pyonghaeng-saseon-dobeob, that is familiar drawing type in the Korean traditional paintings. From this expression we can deduce that the traditional architectural drawings such as Sukcheon-je-a-do were constructed by the traditional landscape painters.

The combined method utilizing airborne LiDAR and GIS data is suggested to extract 3-dimensional hybrid city model including roads and buildings. Combining the two types of data is more efficient to estimate the elevations of various types of roads and buildings than using either LiDAR or GIS data only. This method is particularly useful to model the overlapped roads around the so called spaghetti junction. The preliminary model is constructed from the LiDAR data, which can give wrong information around the overlapped parts. And then, the erratic vertex points are detected by imposing maximum vertical grade allowable on the elevated roads. For the purpose of efficiency, the erratic vertex points are corrected through linear interpolation method. To avoid the erratic treatment of the LiDAR data on the facades of buildings 2 meter inner-buffer zone is proposed to efficiently estimate the height of a building. It is validated by the mean value (=5.1%) of differences between estimated elevations on 2 m inner buffer zone and randomly observed building elevations.

The ability to efficiently and robustly recover accurate 3D terrain models from sets of stereoscopic images is important to many civilian and military applications. A stereo matching has been an important tool for reconstructing three dimensional terrain. However, there exist many factors causing stereo matching error, such as occlusion, no feature or repetitive pattern in the correlation window, intensity variation, etc. Among them, occlusion can be only resolved by true multi-image stereo. In this paper, we present multi-image stereo method using DEM fusion as one of efficient and reliable true multi-image methods. Elevations generated by all pairs of images are combined by the fusion process which accepts an accurate elevation and rejects an outlier. We propose three fusion schemes: THD(Thresholding), BPS(Best Pair Selection) and MS(Median Selection). THD averages elevations after rejecting outliers by thresholding, while BPS selects the most reliable elevation. To determine the reliability of a elevation or detect the outlier, we employ the measure of self-consistency. The last scheme, MS, selects the median value of elevations. We test the effectiveness of the proposed methods with a quantitative analysis using simulated images. Experimental results indicate that all three fusion schemes showed much better improvement over the conventional binocular stereo in natural terrain of 29 Palms and urban site of Avenches.
