As part of an effort to leap smart cadastre system by doing rearrangement of various mismatches in the land register, the cadastre renovation project is being recently conducted. In response to this demand, this paper proposes an image-based rapid parcel boundary demarcation plan using the high resolution aerial image with a GSD (Ground Sample Distance) of 5cm that matches to real ground boundary situation in residential area. To review the feasibility and accuracy of this proposed methodology, we compared the accuracy of parcel boundary point and parcel area extracted from the digital stereo plotting on the basis of results of cadastral boundary surveying and land register over the selected two test areas. The comparative accuracy result of all boundary points by digital stereo plotting is satisfied with accuracy requirement according to the criteria of the enforcement regulation of cadastral surveying, whereas it exceeded allowable error of ${\pm}0.07m$, more strictly specified in the Special Act on Cadastral Renovation. And about 20% of the total 70 parcels extracted by digital plotting are out of area tolerance in Jecheon study area, and 10% of the total 19 parcels in Suwon study area. The parcels exceeding accuracy limit are mostly due to the occlusion caused by building roof or eaves, and the obstacles such as trees existing on the boundary. Furthermore, an object identification is impossible in image because of vague boundary reference in case of nonexistence of man-made structures or natural features. Therefore, the utilization of boundary identification stickers is recommended as a solution for these types of land parcel.

The use of royal artificial flowers was finally found through schematics and records in Wonhaeng Eulmyojeongri Uigwe, which organized the procession to Hwaseong in 1795. The results of classifying the uses of artificial flowers in the brthday banquet at Bongsudang Hall in 1795 and considering the shape, user, and usage are as follows. According to literature records, artificial flowers were made with high-quality materials such as gold, silver, and silk thread in the early period, but were mainly made of paper in the later period. Artificial flowers were used for decorating official hats, Bongsudang Hall, and banquet tables. The Sagwonhwa was used for decoration of the official hats of members of the royal family, and the one on the top was called Eosam-Sagwonhwa. At the birthday banquet inBongsudang Hall, King Jeongjo and Hyegyeonggung used the Eosam-Sagwonhwa and put it on the right side of the official hats. Officials put peach blossom with two petals on the left side of the official hats for decoration. The artificial flowers for decoration of the official hats of musicians and dancers were more expensive and flashier than the officials' ones. Depending on the dance, several artificial flowers were inserted into the official hats. When measuring the size of artificial flowers, the scale used was when making a ceremonial article. For artificial flowers for decoration of the banquet hall, red and white peach blossoms were placed in two jars with dragons painted on them and them placed on two red-painted tables, respectively. The table and jar with flowers were tied together with a red cotton string and fixed so as not to fall over. The artificial flowers for decoration of the banquet table of King Jeongjo, Hyegyeonggung, and the king's sisters were a large lotus, medium-sized lotus, peony, rose, and specially made peach flowers. The artificial flowers for decoration of the banquet table of guests and officials were small lotuses and peach blossoms. The artificial flowers used in the birthday banquet at Bongsudang Hall the most were peach blossoms, and peaches had the meaning of longevity and exorcism. It is expected that the above research results will be helpful in understanding the characteristics and usage of artificial flowers in the period of King Jeongjo and use in reproducing royal feasts and producing traditional cultural contents.

국토정보의 3차원 모형 생성에 관한 관심이 대두되면서 효율적인 3차원 자로 구축에 대한 연구가 진행되고 있다. 특히 도심 지역의 건물 고도 모형 생성에 관하여 항공사진, 위성영상 및 LIDAR에 관한 기법 개발이 활발해 지고 있다. 항공사진 및 위성영상만을 이용하여 건물고도 모형을 생성할 경우, 기복변위로 인해 입체 영상의 영상정합 시 오정합이 발생하므로 건물 고도 모형 생성에는 많은 어려움이 있다 이에 단일 자료만을 이용하지 않고 관련 자료원을 함께 사용함으로써 보다 효과적이고 정확한 자료 생성을 위하여 항공사진과 수치지형도를 활용하는 연구가 수행되고 있다. 본 연구에서는 수치지형도(1/1,000)와 항공사진(1/5,000)을 이용하여 효과적인 건물 고도 모형 생성 관한 연구를 수행하였으며, 관심점 검출 기법과 영상 정합 시 탐색 범위의 기하학적 제약 수단인 수직선 제적 이론을 병합한 새로운 기법을 개발하였다. 본 연구 성과를 검증하기 위하여 연구 성과와 수치도화 장비를 이용한 건물 고도 모형과의 정확도를 비교 평가하였다.

Purpose: The purpose of this study was to investigate the relationships between problem behavior, school stressor and family strength in high-school girls. Methods: Data were collected from 200 high school girls in 2008. Data were analyzed with SPSS/WIN 18.0. Results: There was a positive correlation between problem behavior and school stressor. There was a negative correlation between problem behavior and family strength. The predictors of problem behavior were school stressor, family strength, and monthly family income and these factors explained 43.0% of problem behavior. Conclusion: The findings of this study suggest the necessity of developing nursing intervention programs for enhancing high-school girls' skills in interpersonal relationship and communication to decrease school stressor and increase family strength.

다사다난했던 한 해가 지나고 새로운 세기의 새 아침이 밝았습니다. 이제 우리는 지난날의 시련을 발판으로 새천년 새해를 알차게 설계하면서 내일을 차분히 준비해야 합니다. 지난해 위리 정보 통신 업계는 참으로 많은 일들을 겪었습니다. 일부 벤처 기업가들의 삐뚤어진 행각이 결국은 전체 벤처 업계의 심각한 자금난을 야기하는 도화선이 되었으며, 실제 가치보다 부풀려진 미래 가치 때문에 느닷없는 거품론에 휩싸이면서 경제 전반에 좋지 않은 영향을 미친것이 사실입니다. 하지만 지금과 같이 제2의 IMF를 우려하는 경제 침체기에 있어서 그 해법을 제시할 수 있는 유일한 수단이 바로 우리가 그 동안 수많은 땀방울을 흘리면서 일구어 놓은 선진화된 정보 통신 산업일 것입니다. 더구나 정보 통신 산업은 시너지효과를 창출할 절대절명의 대안으로 우리에게 새로운 성공신화를 안겨 줄 수 있는 희망입니다. 새해에는 정보통신 업계가 더욱 힘차게 도약할 수 있는 한 해가 되길 기원합니다. 이제 한강의 기적이 아닌 테헤란밸리의 기적을 꿈꾸면서, 새해에는 정보 통신 업계가 더욱 힘차게 도약할 수 있는 한 해가 되길 기원합니다.

'Special Records' means the records created by the government power authorities like security, investigation, intelligence agencies. Even after the enactment of the Public Records Act, these kinds of records were out of the control of the National Archives of Korea. The reason was certainly complex including the loss of control power caused by the National Archives' low status, limitation of the legislation and lack of positive measures for the transfer of classified records. But core records of the government power authorities should be transferred to the National Archives for the righteous records culture in the democracy. This paper investigates the problems concerned with the transfer of classified records of the special records center, looking for a practical alternative.

A total of 48 dust samples were collected from large shopping mall parking lots in Daegu metropolitan city in March 2011. Samples were sieved through a 100 ${\mu}m$ mesh and the concentration of 14 elements have been determined using by ICP after acid extraction. Results showed that Ca, Fe, K, Mg, Mn, Na and V were affected by natural sources while Cd, Cr, Cu, Ni, Pb and Zn were affected by anthropogenic sources. The measured values were remarkably higher in components from natural sources than in components from anthropogenic sources. Anthropogenic trace element concentrations of ground roof dust were higher than those of ground and underground indoor dust. A large percentage of trace elements came from natural sources rather than anthropogenic sources. The percentage composition of chemicals of ground roof dust were higher than those of ground and underground indoor dust. This study showed that investigated parking lots were rarely contaminated with hazardous heavy metals. The heavy metal pollution of ground roof were higher than those of ground and underground indoors. The correlation analysis among trace elements suggest that components in ground roof were more highly correlated than those in ground and underground indoor. Also anthropogenic trace element levels were well correlated with parking lot age and parking density.
