사용자가 가능한 센서 가까이에서 이동하는 문제를 최단거리유지문제라 하며, 무선 연결의 안정성을 높이기 위해서 두 개의 센서로부터 가까이에 위치하여 사용자가 움직이는 이동경로를 차선최단거리유지이동경로라고 한다. 이 논문에서는 주어진 센서들의 집합 U와 시작점 s, 끝점 t가 주어질 때, s에서 t까지 이르는 경로로서, 가장 가까운 두 개의 센서까지의 거리가 최소인 차선최단거리유지이동경로를 찾는 $O((c^2n+e)log(c^2n))$-시간 알고리즘을 제시한다. 여기서 c는 집합 U의 하나의 사이트가 갖는 최대 보로노이 선분의 개수이다.

최근 웹과 가상환경에서는 사실감과 몰입감을 증대시키고 사용자와 상호작용 할 수 있는 아바타의 연구가 활발히 이루어지고 있으나, 아바타 동작의 제어를 위한 기존의 연구들은 하위 동작과 관련된 복잡한 데이터를 포함하고 있어서 사용자가 작성하기에는 난해한 점이 많았고, 다양한 작업 도메인에 적용할 때에는 해당 도메인에 맞게 언어를 재 작성해야 하는 문제점이 있었다. 따라서 본 연구에서는 사용자가 작성하기 쉬운 형태로 정의된 작업수준의 행위 표현 언어와 작성된 행위의 세부 동작들을 위한 동작 표현 언어를 각각 정의하고, 행위 표현 언어를 동작 표현 언어로 변환시키기 위해 Interpreter를 구현하였으며, 아바타의 모션라이브러리를 구축하여 Cyberclass 아바타 시스템을 구현하였다 또한 제안된 행위 표현 언어를 기존 연구와 비교하여, 행위 표현 언어가 아바타의 행위에 대해 좀 더 간단하게 작성 되는 것을 알 수 있었다.

The purpose of this study was to clarify the relationship between life style and housing satisfaction of high school students. This is the investigation of which 1015 high school students live in Chonbuk province. In this statistical analysis, SPSS program was utilized to calculate percentage, mean and standard deviation. Also. these materials were verified by t-test, one-way ANOVA, Pearson's correlation coefficient. The main results of this study were as follows. There was a significant difference between life style and housing satisfaction, according to demographic variables and housing characteristic variables. The entire life style has been appeared high type of a along with PC. Most of students has been appeared high in health and security of housing. Also, correlation of life style and housing satisfaction showed significantly. On the basic of these results, it can be suggested : It is necessary to have the righteous understanding about life style and housing satisfaction, of high school students for advisable guidance of housing education. It needed to continue diversified researches considering spread of life style 'with PC' and enough awareness of health and security in housing satisfaction.

Three neonatal pigs from the same litter in a domestic farm were born with skin lesions. Grossly, multiple well-circumscribed, round papules distributed over the skin of the three piglets. Two piglets were submitted for a diagnosis of skin disease. Microscopically, epidermal hyperplasia with ballooning degeneration of stratum spinosum keratinocytes was observed. Some keratinocytes contained eosinophilic intracytoplasmic inclusions and a central nuclear vacuole and chromatin margination. Swinepox (SWP) virus was detected by polymerase chain reaction and nucleotide sequencing, and Staphylococcus hyicus was isolated in skin lesions. Based on the gross findings and laboratory results, these piglets were diagnosed with congenital SWP with a secondary staphylococcal infection.

After the Qing Dynasty overthrow of the Ming dynasty, this is far-reaching influenced on the Ming Dynasty's Sovereign state of the Joseon dynasty. Not only did regulations prohibit the entry into various books published by the Qing Dynasty, In addition, the "Northern Expedition" of Song Siyeo put forward the mainstream political proposal of the Northern Expedition and Qing Dynasty.Even in this context, Representatives of scholars such as Hong Daeyong, Bak Jega, Kim Jeonghui on the Joseon dynasty peninsula at the time, put forward the idea of "Learning from Central Plains" through several visits to Shuntian Prefecture (now Beijing), And gradually formed the well-known Silhak (Practical Learning) ideological of "Bukhak, (Northern Learning)" in the Joseon dynasty history. the Joseon dynasty Silhak ideological scholar of Kim Jeonghui also was under the influence of the Weng Fanggang and Ruan yuan other famous Qing Dynasty Textual scholar, Fruitful achievements in Chinese Classical Studies Epigraphy, Calligraphy.He founded the "Chusa-che" style of calligraphy Chusa, the "Chusa-che" styled is although born out of the clerical script, but more composition and See also asymmetrical in harmony, Strong and vigorous brush strokes, Every word vibrant, Make it a master of gold stone calligraphy in the Joseon Dynasty.This study based on some records of Kim Jeonghui's visited to Shuntian Prefecture(now Beijing), this article examines the academic activities of seeking truth to facts in Korea and the Qing Dynasty at the time, and the impact on these activities on calligraphy and painting in the Joseon Dynasty.

Four Wangs' landscape style (四王山水畵風), which had appeared in Beijing in the early 18th century, widely spread to Korea and Japan in the 19th century and became a significant basis for developing new painting styles in both countries. It was first introduced to Korea by Shin Wi (申緯) and Kim Jeong-hee (金正喜) who associated with literary men of the Qing Dynasty. Being influenced by them directly or indirectly, Shin Myeong-yeon (申命淵), Yi Han-cheol (李漢喆), Yu Suk (劉淑), Changv Seung-eop (張承業), An Choog-sik (安中植), and Jo Seok-jin (趙錫晋) attempted to adapt Four Wangs' landscape style and it later became a main Stream painting style of the Korean painting circles. Based on Four Wangs' landscape style, their landscape paintings had something in common in that they captured natural features from a short distance using the Down-Up prospective and placed guardian mountains across mountain streams by making a tall tree in the right or left bottom of the canvas as the starting point. However, recently unveiled court painter An Geon-yeong (1841~1876)'s the Landscape Screen is remarkable in that it is based on Four Wangs' style, which was in fashion in the late 19th century, but shows different aspects from other Four Wangs' style paintings in terms of feature capturing, brush stroke and colors. While most of An Geon-yeong's existing paintings are small ones, this folding screen is a big piece consisting of six-fold landscape paintings. In particular, it shows new aspects by creating a serene and calm atmosphere through the description of various landscape scenes with thin brush strokes using glossy ink, by showing a macroscopic view in some paintings through feature capture using a birds-eye view method, and by giving life to the canvas through smoke and clouds. This painting style is considered to be linked with those of Wang Xue-hao (王學浩, 1754~1832), Tang Yifen (湯貽汾, 1778~1853) and Dai Xi (戴熙, 1801~1860), based on Four Wangs' style in the early 19th century's Jiangnan Circle (江南 畵壇), who tried to express the energy and vitality of real landscapes by going around China's well-known mountains and complementing painting styles with drawing from nature. Therefore, An Geon-yeong's six-fold Landscape Screen is very significant as a rare case proving the introduction and reception of Jiangnan Circle's Four Wangs' landscape style which was different in many aspects from Beijing Circle in the 19th century.

Purpose: The purpose of this study was to evaluate the methodological quality of nursing studies using structural equation modeling in Korea. Methods: Databases of KISS, DBPIA, and National Assembly Library up to March 2014 were searched using the MeSH terms 'nursing', 'structure', 'model'. A total of 152 studies were screened. After removal of duplicates and non-relevant titles, 61 papers were read in full. Results: Of the sixty-one articles retrieved, 14 studies were published between 1992 and 2000, 27, between 2001 and 2010, and 20, between 2011 and March 2014. The methodological quality of the review examined varied considerably. Conclusion: The findings of this study suggest that more rigorous research is necessary to address theoretical identification, two indicator rule, distribution of sample, treatment of missing values, mediator effect, discriminant validity, convergent validity, post hoc model modification, equivalent models issues, and alternative models issues should be undergone. Further research with robust consistent methodological study designs from model identification to model respecification is needed to improve the validity of the research.

Photoreactions of pseudosaccharin pyridinemethyl ethers have been investigated. Pseudosaccharin 2-pyridinemethyl ether, pseudosaccharin 4-pyridinemethyl ether and pseudosaccharin 3-pyridinemethyl ether all undergo a facile photoreaction via reaction pathways involving homolysis of the bond between pseudosaccharyl oxygen and pyridinemethyl carbon, and excited nucleophilic substitution of pyridinemethoxy group by solvent, methanol which are not quenched by oxygen present in the reaction. Product yield demonstrates that the homolysis pathway predominates over the nucleophilic substitution.
