본 논문에서는 키넥트 센서 기반으로 하는 동작 인식 애플리케이션을 설계하고 구현 한다. 이 애플리케이션은 본인이 응원하는 특정 연예인의 영상을 보고, 응원하는 동작을 하면 점수를 취득하게 되고, 누적되는 점수에 따라 그 연예인에 대한 기여도를 알 수 있도록 구현한다. 프레임별 조인트 움직임의 차이를 구하여 사용자의 움직임에 따른 점수를 부여하는 기능을 구현한다. 또한 전체 랭킹 시스템을 통해 동일한 연예인을 응원하는 사용자들이 공동의 소속감을 가지고, 더 나아가 자신들이 응원하는 연예인의 순위를 올리기 위한 경쟁을 유도하는 기능을 구현한다. 점수가 누적되면 단계별로 추가적인 애니메이션을 제공하여 흥미있게 볼 수 있는 기능도 구현한다.

This Study examines the relationship between Cumulative Risk and Behavioral Problem of children's in divorced family. The cumulative risk was Summed for each children to creative an cumulative scores. Scores on the index ranged from 0 to 12. Cumulative Risk was associated with Behavioral Problem. Moreover the analyses revealed positive, linear associated between Cumulative Risk and Behavioral Problem. Cumulative Risk predicted Problem Behavioral of Divorced Family's Children. Finding indicate that the amount of risk in Divorced Family's childrens lives was useful for determining the extent to which cumulative risk exposure plays an etiological role in Behavioral Problem. On the basis of these results, this article provided some suggestions for promoting of children welfare.

Peer assessment refers to having students, rather than the instructor, make assessments of one another's work. Peer assessment is often used as a tool to train writing skills or a tool to apply or extend learning in higher education. Park(2016) recently proposed a system which utilizes peer assessment as a part of preparatory activity for college courses. Before weekly class, students studied given material on their own, wrote a one page essay on a given question based on their reading, and assessed the essays of other students. In this study, the system was implemented in undergraduate courses at S University over 2 semesters and the results were analyzed. The reliability of weekly scores given by students was not very high, but the correlation was high between the cumulative scores given by students across weeks and the scores of the end of the term paper assessed by the instructor. Based on these findings, the possibility of utilizing the results of the peer assessments as part of the final grades was discussed.

Over the last couple of years, established Cumulus Pricing Scheme(CPS) has become an important research issue for efficiently charging differentiated internet services. This paper proposes the adjusted CPS technique that expressed information of over or under-use of resources in bandwidth. And, 1 propose CPS with respect to the six main pricing and charging conditions. Also, accumulation technique may indicate an information between specified charging and eventually requires to adapt the initial contract. So called red and green Cumulus Points(CP) are used to judge the behavior of customer. At this point, the actual resource consumption is described by function v(t) at time t.

Stereo matching techniques are categorized in two major schemes, local and global matching techniques. In global matching schemes, several investigations are introduced, where cost accumulation is performed in multiple matching lines. In this paper, we introduce a new multi-line stereo matching techniques which expands a conventional single-line matching scheme to multiple one. Matching cost is based on simple normalized cross correlation. We expand the scan-line optimization technique to a multi-line scan-line optimization technique. The proposed technique first generates a reliability image, which is iteratively updated based on the previous reliability measure. After some number of iterations, the reliability image is completed by a hole-filling algorithm. The hole-filling algorithm introduces a disparity score table which records the disparity score of the current pixel. The disparity of an empty pixel is determined by comparing the scores of the neighboring pixels. The proposed technique is tested using the Middlebury and CMU stereo images. The error analysis shows that the proposed matching technique yields better performance than using conventional global matching algorithm.

The purpose of this study was to identify the factors influencing file-up family stress in the caregivers of patients with dementia. Data was collected by questionnaires from 102 families with a member having a dementia, at neurology departments of hospitals, temporary shelter for dementia patient, and nursing homes for the elderly. The data was analyzed using descriptive statistics, pearson correlation coefficients, and multiple regression. In results, the score of file-up stress showed a significantly negative correlation with the score of level of family hardiness(r=-.200, p=.026), social support(r=-.361, p=.004), relative and friend support(r=-.416, p=.001), and F-COPES(r=-.345, p=.048). The multiple regression analysis revealed that the most powerful predictor of file-up family stress was family cost for patients with dementia. The results contribute to the understanding of Korean family caregivers' perceptions of caregiveing. Further researches should be conducted with the consideration of Korean traditional custom that family should take care of the elderly family members.

This paper considers a procedure for the economic design of a cumulative score(CUSCORE) control chart and more sensitive than X-type control chart for small shift to control the mean of a process with a exponentially distributed quality characteristic. An expected loss - cost model as a function of design variables(sample size, sampling interval, scoring limit and decision limit) is derived. Direct search techniques are used to optimize the model subject to ARL in control. Numerical examples and sensitivity analysis of the model are presented. For selected values of situation parameters a comparison study with CUSUM charts is given. CUSCORE control charts compare favourably with CUSUM charts in cost for speedy production process. The proposed control chart can be directly applied for controlling the lifetime characteristics.

기존의 웹 기반 학습 평가 시스템은 학습자의 선택 기회가 없는 상태에서 일방적으로 제시된 문제지로 평가하게 되거나, 문제 은행에서 임의로 추출한 문제도 단순히 무작위로나 난이도만을 고려하여 문제지를 구성하였고, 그 결과에 대한 성취도의 분석도 한 문제지에 대한 정오표 또는 점수로 단순하게 제시하기 때문에 학습자의 지속적인 학습 관리가 이루어지지 못하고 있다. 본 논문에서는 문제유형, 과목 및 단원 난이도, 문항 형태, 문항당 배점, 문항당 배당 시간등의 다양한 정보를 가진 유형별 문제 은행을 구축하였다. 학습자는 마치 문제집을 풀고 싶은 유형의 문제를 선택하듯이 문제 은행에서 문제를 자율적으로 구성하여 평가할 수 있는 유형별 문제지나 대학수학능력시험의 기준에 맞추어 자동 구성되는 종합 문제지로 다양하게 평가할 수 있다. 또한, 한문제지에 대한 결과뿐만 아니라 유형별, 월별 성취도 분석을 통하여 평가한 총점에 대한 획득한 점수의 누적 통계를 그래프로 일목요연하게 보여주어 한 학습자에 대한 지속적인 성취도 분석이 가능하도록 구축하였다.

This paper proposes a method of designing one-sided cumulative scored control charts to control the process mean with a normally distributed quality characteristic. The average run length(ARL) is obtained from the average sample number of sequential probability ratio test(SPRT) on trinomial distribution. Using the analogy between cumulative scored control chart and SPRT for trinomial observations, a procedure is presented to determine three control chart parameters; lower and u, pp.r scoring boundaries and action limit. The parameters are determined by minimizing the ARL when the process is out of control with prespecified ARL when the process is in control.

This study determined appropriate threshold level (cumulative period and percentage) of precipitation for drought management in dam basin. The 5 dam basins were selected, the daily dam storage level and daily precipitation data were collected. MAP (Mean Areal Precipitation was calculated by using Thiessen polygon method, and MAP were converted to accumulated values for 6 cumulative periods (30-, 60-, 90-, 180-, 270-, and 360-day). The correlation coefficient and ratio of variation coefficient between storage level and MAP for 6 cumulative periods were used to determine the appropriate cumulative period. Correlation of cumulative precipitation below 90-day was low, and that of 270-day was high. Correlation was high when the past precipitation during the flood period was included within the cumulative period. The ratio of variation coefficient was higher for the shorter cumulative period and lower for the longer in all dam, and that of 270-day precipitation was closed to 1.0 in every month. ROC (Receiver Operating Characteristics) analysis with TLWSA (Threshold Line of Water Supply Adjustment) was used to determine the percentage of precipitation shortages. It is showed that the percentage of 270-day cumulative precipitation on Boryung dam and other 4-dam were less than 90% and 80% as threshold level respectively, when the storage was below the attention level. The relationship between storage and percentage of dam outflow and precipitation were analyzed to evaluate the impact of artificial dam operations on drought analysis, and the magnitude of dam outflow caused uncertainty in the analysis between precipitation and storage data. It is concluded that threshold level should be considered for dam drought analysis using based on precipitation.
