Objectives : This study was performed to investigate the relationship between decision making style and learning style according to Sasang constitution. Methods : The subjects were 213 nursing students of K college in Jeonbuk, and the period of data gathering was limited from 1 Sep. 2009 to 7 Sep. 2009. The instrument tools included QSCC II, decision making style, and learning style. The collected data were analyzed by SPSS-PC programme. Results : 1. Decision making style: Soeumin group had significantly high score in rational score compared with Soyangin(F=7.174 p=.001), and in dependent score compared with Taeumin and Soyangin (F=3.414, p=.035). 2. Learning style: Soyangin group had significantly high score in cooperation score compared with Taeumin(F=5.688 p=.004), and Taeumin group had significantly high score in emulous score compared with Soeumin and Soyangin (F=.148, p=.002). Conclusions : In conclusion, it was found that decision making style and learning style are significantly different according to Sasang constitution. Therefore, these results suggest that nursing educational program needs to be developed considering Sasang constitution.

Purpose: Recently, propensity score matching method is used in a large number of research paper, nonetheless, there is no research using fitness test of before and after propensity score matching. Therefore, comparing fitness of before and after propensity score matching by logistic regression analysis using data from 'online survey of adolescent health' is the main significance of this research. Method: Data that has similar propensity in two groups is extracted by using propensity score matching then implement logistic regression analysis on before and after matching separately. Results: To test fitness of logistic regression analysis model, we use Model summary, -2Log Likelihood and Hosmer-Lomeshow methods. As a result, it is confirmed that the data after matching is more suitable for logistic regression analysis than data before matching. Conclusion: Therefore, better result which has appropriate fitness will be shown by using propensity score matching shows better result which has better fitness.

Background and purpose : Health is characterized by variability and a loss variability is associated with aging and disease. Normal healthy respiratory patterns are characterized by breath to breath variability. Cold-Heat score are quantified indices in Korean Medicine. The aim of this study is to analyze relations between 9 respiratory indices (including breath to breath variability) and cold-heat score by questionnaire. Method : Respiratory data were measured during 15 minutes and transferred to text file. We calculated 9 respiratory parameters in use of MATLAB7.1. After then we did correlation analysis of 9 respiratory indices and cold-heat score Results and conclusion : EIratio is showed significant correlation with Cold score and weighted Heat score.

Purpose：The purpose of this study was to find the effect of intensive therapy on gross motor function measure(GMFM) score in cerebral palsy. Methods：Twenty eight cerebral palsy children were recruited in this study. Gross motor Function Measure(GMFM) score and Gross motor Function Classification System(GMFCS) were used to evaluate as functional change and functional level. Intensive therapy period for cerebral palsy children was 3, 4, and 5 weeks. Statistical analysis was used paired T test and one way ANOVA to know change between pre and post therapy was used. Results：GMFM Score of pre- and post- intensive therapy showed the statistically significant difference. Intensive therapy period indicated the statistically significant difference in GMFM score. GMFCS level did not reveal statistically significant difference in GMFM score. Conclusion：Intensive therapy was effective on gross motor function measure(GMFM) score in cerebral palsy.

Anomaly detection in human movements can improve safety in indoor workplaces. In this paper, we design a framework for detecting anomalous trajectories of humans in indoor spaces based on a variational autoencoder (VAE) with Bi-LSTM layers. First, the VAE is trained to capture the latent representation of normal trajectories. Then the abnormality of a new trajectory is checked using the trained VAE. In this step, the anomaly score of the trajectory is determined using the trajectory reconstruction error through the VAE. If the anomaly score exceeds a threshold, the trajectory is detected as an anomaly. To select the anomaly threshold, a new metric called D-score is proposed, which measures the difference between recall and precision. The anomaly threshold is selected according to the minimum value of the D-score on the validation set. The MIT Badge dataset, which is a real trajectory dataset of workers in indoor space, is used to evaluate the proposed framework. The experiment results show that our framework effectively identifies abnormal trajectories with 81.22% in terms of the F1-score.

The set S of distinct scores (outdegrees) of the vertices of a k-partite tournament T($X_l,\;X_2, ..., X_k$) is called its score set. In this paper, we prove that every set of n non-negative integers, except {0} and {0, 1}, is a score set of some 3-partite tournament. We also prove that every set of n non-negative integers is a score set of some k-partite tournament for every $n{\ge}k{\ge}2$.

We first introduce the quasi-score estimating function and applied the quasi-score estimating function to nonlinear time series models. We proposed the M quasi-score estimating functions bounded functions for the quasi-score estimating functions. Also, we investigated the asymptotic properties of quasi-likelihood estimators and M quasi-likelihood estimators. Simulation results show that the M quasi-likelihood estimators work better than the least squares estimators under the heavy-tailed distributions

XML은 HTML의 단순성과 SGML의 복잡성을 동시에 극복하기 위한 노력으로 시작되어 HTML이나 SGML과는 다른 새로운 세계를 만들어 내고 있으며, 인터넷 문서 표현과 관련된 여러 분야에서 활발하게 연구되고 있다. 이 논문에서는 차세대 인터넷 문서 표현 언어로 주목받고 있는 XML을 이용하여 합창곡의 악보를 표현하는 기법을 제시한다. 이 논문에서는 합창곡 악보를 표현하기 위해 정의된 새로운 마크업 언어인 ScoreML(Score Markup Language)을 소개하고, ScoreML로 작성된 XML 문서를 웹에서 볼 수 있도록 ScoreML 브라우저의 설계 및 구현에 대해 기술한다. ScoreML을 사용하여 작성된 XML 문서는 악보 표현뿐만 아니라 음악 데이터의 저장과 검색에도 사용될 수 있다.

최근 유방 영상 검사는 의료영상저장전송시스템(Picture Archiving and Communication System, PACS)의 도입과 특수의료장비에 관한 정도관리 실시로 인해 Computed Radiography(CR)과 Digital Radiography(DR)에 관한 관심도와 이용도가 증가하고 있는 추세이다. 본 연구는 유방영상검사에 이용되고 있는 각 시스템별 검출기의 영상 화질을 정도관리 시 사용되는 ACR 팬텀을 이용하여 비교 분석하였다. 평가 방법은 심리적인 방법으로 ACR 팬텀을 이용한 영상의 수치 값을 SPSS 통계프로그램을 이용하여 유의성과 신뢰도를 분석한 결과는 다음과 같다. 1. Fiber에서는 Screen-Film인 경우 3.9점, CR($50\;{\mu}m$)인 경우 4.2점, CR($100\;{\mu}m$)인 경우 3.2점, DR인 경우 4.2점을 얻어 CR($50\;{\mu}m$), DR, Screen-Film, CR($100\;{\mu}m$)순으로 높은 점수를 받았다(P<0.05). 2. Calcification은 Screen-Film인 경우 2.7점, CR($50\;{\mu}m$)인 경우 2.5점, CR($100\;{\mu}m$)인 경우 2.0점, DR인 경우 2.9점을 얻어 DR, Screen-Film, CR($50\;{\mu}m$), CR($100\;{\mu}m$) 순으로 높은 점수를 받았다(0.025(P<0.05). 3. Mass는 Screen-Film인 경우 3.8점, CR($50\;{\mu}m$)인 경우 3.8점, CR($100\;{\mu}m$)인 경우 3.6점, DR인 경우 4.5점을 얻어 DR, CR($50\;{\mu}m$), Screen-Film, CR($100\;{\mu}m$) 순으로 높은 점수를 받았다(P<0.1). 4. 합계점수 평가는 Screen-Film인 경우 10.4점, CR($50\;{\mu}m$)인 경우 10.6점, CR($100\;{\mu}m$)인 경우 8.7점, DR인 경우 11.3점을 얻어 DR, CR($50\;{\mu}m$), Screen-Film, CR($100\;{\mu}m$) 순으로 높은 점수를 받았다. 이상의 결과는 DR, Screen-Film시스템이 CR($100\;{\mu}m$)에 비해 화질이 우수하다는 것을 알 수 있다. 하지만 DR은 소자에 의한 불안정성, Screen-Film은 artifact에 의한 화질 저하 등 단점을 가지고 있으며, 화질 저하가 문제였던 CR시스템 중 Dual-Side방식의 CR($50\;{\mu}m$)을 사용한 경우에는 Screen-Film 시스템과 차이가 없는 것으로 나타났다. 향후 방사선 영상검사가 디지털화 되는 추세이므로 유방영상검사도 각 시스템의 발전과 보완이 필요할 것으로 사료된다.
