Purpose: The purpose of this study aims to provide a fundamental basis for more efficient human resource management of hospitals through career development and through lowering the rate of turnover of nurses. Method: The target group was 370 nurses who are currently employed at four general hospitals. Three hundred and twenty-nine documents were collected, and the statistical results were generated by the SAS program. Result: The average mean score of organizational commitment, career commitment and turnover intention were: 3.13 points for affective commitment, 3.09 points for continuance commitment and 2.92 points for normative commitment, out of a five point scale. The average mean score of career commitment and turnover intention was 2.89 and 3.28 points. The most influential variable in turnover intention was affective commitment out of organizational commitment. Conclusions: This study verified that organizational commitment and career commitment are key variables that could decrease turnover intentions.

Since the digital chart consists of a large number of points, the effective method for the coastline data compression(CDC), storing the data compactly and reproducting the coastline feature accurately, is important. In the CDC, the key technique is to determine the optimal positions as node points in given coastlines. In this paper, a new CDC method, selecting node points with conspicuous coast positions in the view point on navigation and adopting spline interpolation to the nodes partly, is proposed. Using the northern part of KEOJE-DO coastline in Korean chart No.204, CDC experiments are carrie out with various compression ratio. The results fro the influence of coastline shape according to various CDC methods are discussed and presented.

본 연구는 치위생(학)과 학생들의 직업기초역량이 진로의사결정에 미치는 융합적 영향요인을 파악하고자 부산과 울산지역의 대학교 치위생(학)과에 재학중이며, 임상실습 경험이 있는 학생 196명을 조사하였다. 수집된 자료는 SPSS 24.0 프로그램을 통해 빈도분석, 상관분석, 선형회귀분석을 사용하여 산출하였다. 연구대상자의 직업기초역량 인식수준은 3.38점, 진로의사결정은 3.30점으로 나타났으며, 직업기초역량의 하부요인 중 직업윤리 인식 수준이 3.46점으로 가장 높게 나타났다. 직업기초역량이 진로의사결정에 미치는 영향요인으로 대인관계능력(p<0.01), 조직이해능력(p<0.01), 자원관리능력(p<0.01), 자기개발능력(p<0.05), 문제해결능력(p<0.05), 수리능력(p<0.05)에서 유의한 수준으로 나타났다. 따라서 치위생(학)과 학생들의 직업기초역량 강화는 진로의사결정을 하는데 중요한 기여요소이므로 치위생 교육이 전공역량과 더불어 직업기초역량을 골고루 갖출 수 있도록 학생개인, 학과, 대학차원의 융합적 노력과 교육과정 개발이 이루어져야 할 것이다.

Inter-granular Bright Points (igBPs) are small-scale objects in the Solar photosphere which can be seen within dark inter-granular lanes. We present a new algorithm to automatically detect and extract igBPs. Laplacian and Morphological Dilation (LMD) technique is employed by the algorithm. It involves three basic processing steps: (1) obtaining candidate "seed" regions by Laplacian; (2) determining the boundary and size of igBPs by morphological dilation; (3) discarding brighter granules by a probability criterion. For validating our algorithm, we used the observed samples of the Dutch Open Telescope (DOT), collected on April 12, 2007. They contain 180 high-resolution images, and each has a $85{\times}68\;arcsec^2$ field of view (FOV). Two important results are obtained: first, the identified rate of igBPs reaches 95% and is higher than previous results; second, the diameter distribution is $220{\pm}25km$, which is fully consistent with previously published data. We conclude that the presented algorithm can detect and extract igBPs automatically and effectively.

본 논문은 조명 밝기 변화에 강건한 증강현실 시스템을 구현하기 위한 알고리즘을 제안한다. 본 논문에서 제안하는 방법은 미리 객체를 검출한 프레임으로부터 최적의 표본 밝기를 구해 모델링 한 후, 이를 이용하여 히스토그램 명세화를 수행한다. 또한 카메라 변위에 따라 유실된 객체의 특징 정보는 선형 칼만 필터로 추적하였다. 제안된 방법을 사용하였을 때 기존의 방법보다 약 3배 이상 객체 검출률이 향상되었으며, 객체 검출에 실패한 프레임 또한 선형 칼만 필터를 통해 위치 정보를 매우 정확하게 예측할 수 있었다. 본 알고리즘의 효율성을 증명하기 위해 실제 증강 현실을 이용한 게임 시스템에 적용한 결과 기존의 다른 방법보다 성능이 향상됨을 확인 할 수 있었다. 본 알고리즘은 게임 환경이나, 조명 변화가 심한 환경에서도 강건한 증강 현실 시스템의 구현에 적용될 것이라 판단된다.

A three dimensional FE mesh generation scheme based on mapping approach is proposed in this study. A volume in Euclcdian space is represented by composite hyperpatches which are piecewise cubic functions with parameters u,v,w. A key idea in the proposed approach is that sampled grid data points only on the boundary surfaces are needed for the shape representation. Inner points which are necessary of form a hyperpatch are internally generated by Coons patches. This approach is most appropriate for the shapes which are compositions of hexahedron-like shapes and also severely curved.

The insect midgut epithelium is generally lined with a unique chitin and protein structure, the peritrophic membrane (PM), which facilitates food digestion and protects the gut epithelium. We used gel electrophoresis and mass spectrometry to identify the extracted proteins from the silkworm PM to obtain an in-depth understanding of the biological function of the silkworm PM components. A total of 305 proteins, with molecular weights ranging from 8.02 kDa to 788.52 kDa and the isoelectric points ranging from 3.39 to 12.91, were successfully identified. We also found several major classes of PM proteins, i.e. PM chitin-binding protein, invertebrate intestinal mucin, and chitin deacetylase. The protein profile provides a basis for further study of the physiological events in the PM of Bombyx mori.

Quantitative trait loci, a genetic concept for explaining the inheritance of non-Mendelian traits in 1940s, have been realized as particular fragments of chromosome even unique genes in most crops in 21st century. However, only very a small portion of QTL has been screened out by geneticists comparing to a great number of genes underneath the quantitative traits. These identified QTL even have been seldom used into breeding program because crop breeders may not find the QTL in their breeding populations in their field station. Several key points will be proposed to meet the challenges of QTL analysis today: a fine mapping population and the related reference genetic map, QTL evaluation in multiple environments, recognizing real QTL with small genetic effect, map integration.

We suggest a DES key expansion algorithm which is strong enough to overcome Differential Cryptanalysis(DC) and Linear Cryptanalysis(LC). Checking the weak points of DES, we found that the opened S box provide all information on the various kinds of attack. Using the key expansion we redesigned the S box which is not open to anybody who has no key. DC and LC can not be applied to the suggested algorithm without the redesigned S box information. With the computer experiments we show that the efficiency of this algorithm is almost the same as that of DES with respect to the crypto speed.
