다변량 발병시간자료는 각 개개 환자에게 있어 합병증이 발생되거나 혹은 유사 환자군(집락) 내의 발병시간이 상관되어진 생의학자료에서 흔히 볼 수 있다. HMULCOX는 그런 자료를 분석하기 위한 한글 통계 패키지 가운데 하나이다. 이 프로그램은 관련된 발병시간들이 독립이 아닐때에도 COX 비례 위험 모형의 주변확률분포를 계산해 준다. 주어진 조건으로는 주변확률모형의 기본위험율은 일정한 상수, 흑은 변수라도 관계없다. 또한 치료실패율의 치료변수들(공변량)의 효과에 대해 다양한 통계적 추론이 가능하다. 기본적으로 주변확률분포접근법으로 설계되었지만 HMULCOX는 여러 가지 추론 방법을 선택하는 데 일반적으로 충분하다. 이 프로그램으로 2개의 예를 들어 실행하겠다.

기존의 보안시스템은 설비가 비싸고 녹화를 끊임없이 계속함에 따라 저장 용량이 커야하는 문제점이 있고 영상을 단순히 저장하는 외에 다른 부가적 기능이 없다. 본 연구에서는 고성능, 고가의 장비가 아닌 단순한 PC 카메라 와 일반컴퓨터를 이용한 화상 보안 시스템을 제안 한다. 이 시스템은 단순한 녹화 외에 다양한 부가기능을 포함하고 있으며 프로그램이 설치된 컴퓨터를 떠난 외부에서도 감지한 침입을 통보 받을 수 있다. Main Application의 역할은 감시, 재생, 통계, 필터로 분류된다. 카메라에서 실시간으로 보내오는 영상을 메인 프로그램에서 보여주고 일시 정지, 필터 바로 가기 등을 통하여 필터와 연계된다. 이미 저장된 영상은 재생기능을 통하여 재생하며 이제까지 저장된 영상들은 모두 데이터베이스에 통계 화 되어 저장된다. 또한 실시간으로 보여 지는 영상들을 일정한 간격으로 웹 서버로 보내진다.

In this paper, we made a program to compare between population parameters and sample statistics, via Excel macro. This program gathers each students’ files to one file, from which a sample is drawn. This program will help students to be interested in class through extracting a part of sample from a group and comparing the difference between parameters and statistics in a few seconds. In Excel, overlapping value could happen when random numbers are generated but we avoid this case by making the sub-program, without replacement with VBA.

다변량 데이터 분석에 주로 사용되는 차원축소 기법 중 하나인 PCA 알고리즘을 직접 구현해보고 기존의 통계분석 프로그램과 그 결과를 비교분석 해보았다. UCI에서 제공하는 유방암 데이터를 이용하여 실험 해본 결과 두 프로그램 모두 같은 주성분을 얻고, Eigenvalue와 variance도 같은 값을 얻었다. 따라서 상용화된 통계패키지를 사용하지 않고도 PCA 알고리즘을 적용하여 차원축소 문제를 해결하고 데이터를 분석 할 수 있다.

The purpose of this study was to investigate the effect of group music therapy for at-risk Korean soldiers on the levels of adjustment and stress. The study was conducted at a division of the Korean Army with 7 participants who were classified as "at-risk soldiers" based on the results of a psychiatric evaluation, MMPI-II and a personal interview with a counselor. The participants received 12 hours of group music therapy for three weeks and their scores on stress and adjustment inventories were compared before and after the treatment. The pre and post scores were analyzed with the Wilcoxon test for repeated measures. The results revealed that the overall stress level was significantly decreased while there was no significant improvement in the adjustment levels at p < .05. The research findings and personal remarks from the participants suggest that group music therapy may provide effective support for at-risk Korean soldiers in coping with stress and adjustment to military life.

The purpose of this study was to examine the effect of VR news focused on recall, understanding, enjoyment, visual fatigue and reuse intention through experimental study. Using Window SPSS 21.0 and AMOS 21.0 program, the data was analyzed by exploratory/confirmatory factor analysis, reliability analysis, correlation analysis and path analysis. The Results are as follows. First, presence and immersion among VR news characteristics influenced positively on users' recall of VR news. Second, presence, interactivity and immersion among VR news characteristics influenced positively on users' understanding of VR news. Third, presence, interactivity and immersion among VR news characteristics influenced positively on users' enjoyment of VR news. Fourth, presence among VR news characteristics influenced negatively on users' visual fatigue of VR news. Fifth, presence and immersion among VR news characteristics influenced positively on users' reuse intention of VR news. This study will provide on an important implication understanding VR news characteristics and VR news users.

In epidemiology or etiology, we are often interested in identifying areas of elevated risk, so called, hot spot or cluster. Many existing clustering methods only tend to a result if there exists any clustering pattern in study area. Recently, however, lots of newly introduced clustering methods can identify the location, size, and shape of clusters and test if the clusters are statistically significant as well. In this paper, one of most commonly used clustering methods, scan statistic, and its implementation SaTScan software, which is freely available, will be introduced. To exemplify the usage of SaTScan software, we used cancer data from the SEER program of National Cancer Institute of U.S.A.We aimed to help researchers and practitioners, who are interested in spatial cluster detection, using female lung cancer mortality data of the SEER program.

This study was to investigate the effect of career decision-making self-efficacy and social support of university students majoring dance on career preparation behavior. For the study, 300 students from universities in capital area were selected to measure their career decision-making self-efficacy, social support and career preparation behavior. Correlation analysis and multiple regression analysis have been conducted to analyze research question using SPSS Ver. 24.0. The conclusion from results and discussion are as follows. First, there were positive relationships between career decision-making self-efficacy and social support and career preparation behavior. Second, career decision-making self-efficacy influenced career preparation behavior. Third, appraisal support a sub-factors of social support effected on career preparation behavior but emotional support, material support and informational support did not effect on career preparation behavior. Forth, career decision-making self-efficacy effected more than social support on career preparation behavior. Shortly, this study explored that career decision-making self-efficacy influenced career preparation behavior.

The purpose of this study was to analyze the effects of festival experiential factors on festival satisfaction and behavioral intention by questionnaires to 550 experience program participants in the Muju Firefly Festival. And the hypothesis verified by 493 valid questionnaires with AMOS 18.0. The result of analysis showed that educational experience, escapist experience and entertainment experience except esthetic experience had positive effects on the festival satisfaction. Based on standardized coefficients showed that entertainment experience had the greatest impact on the festival visitor's satisfaction. And it showed that the satisfied visitors with the festival experience programs are the more likely re-visit and recommendation of visitors to subsequent festivals.
