In this paper, we propose a visual fatigue prediction metric which considers individual fusional characteristics for stereoscopic video. It predicts the visual fatigue level by examining the disparity and motion characteristics of 3D videos. In addition, we classified the viewers into 2 groups according to fusional limit and the slope of fusional response which are acquired from random dot stereogram test. Then, Pearson's and Spearman's correlation coefficient was measured between the proposed metrics and the subjective results, acquiring 80% and 79%.

Author resolution is to disambiguate same-name author occurrences into real individuals. For this, pair-wise author similarities are computed for author name entities, and then clustering is performed. So far, many studies have employed hierarchical clustering techniques for author disambiguation. However, various hierarchical clustering methods have not been sufficiently investigated. This study covers an empirical evaluation and analysis of hierarchical clustering applied to Korean author resolution, using multiple distance functions such as Dice coefficient, Cosine similarity, Euclidean distance, Jaccard coefficient, Pearson correlation coefficient.

최근 기후변화로 인해 중국, 한국, 일본, 몽골 등을 포함한 동아시아 지역은 태풍, 가뭄, 홍수와 같은 자연재해의 발생 빈도가 증가하고 있는 추세이다. 중국의 경우 2017년 극심한 가뭄으로 1,850만 (ha)의 농작물 피해가 발생하였으며, 몽골 또한 2017년 4월 이후 극심한 가뭄으로 사막화가 급속도로 진행되고 있다. 위성 기반의 강우 자료는 공간과 시간 해상도가 높아짐에 따라 지상관측소 강수량 자료의 대체 수단으로 이용되고 있다. 본 연구에서는 Climate Hazards Groups InfraRed Precipitation with Station (CHIRPS), Precipitation Estimation From Remotely Sensed Information Using Artificial Neural Networks-Climate Data Record (PERSIANN-CDR), Global Precipitation Climatology Centre (GPCC) 강우 위성 자료를 활용하여 기상학적 가뭄지수인 표준강수지수 (Standardized Precipitation Index, SPI)를 산정하였다. 시간 해상도는 월별 영상을 기준으로 2008년부터 2017년까지 지난 10년간의 데이터를 이용하였으며, 각각 격자가 다른 위성영상을 기존 기상관측소와 비교하였다. 피어슨 상관계수 (Pearson Correlation Coefficient, R)를 활용하여 강우 위성 영상과 지상관측소의 상관관계를 분석하고, 평균절대오차 (Mean Absolute Error, MAE), 평균제곱근오차 (Root Mean Square Error, RMSE)를 통해 통계적으로 정확도를 분석하였다. 인공위성 강수량 자료는 미계측 지역이 많은 곳이나 측정이 불가능한 지역에 효율성 측면에서 중요한 이점을 제공할 것으로 판단된다.

This study was conducted to examine cognitive function and the ability for occupational participation in patients with mild and moderate dementia and to identify correlations between these two variables. The study investigated 95 dementia patients who visited a day care center in Daegu between September and November, 2017. Their detailed cognitive functions were examined using the Mini-Mental State Examination-Korean (MMSE-K) and the Korean Version of the Loewenstein Occupational Therapy Cognitive Assessment Geriatric population: LOTCA-G. Their occupational participation was measured using the Model of Human Occupation Screening Tool (MOHOST). The subjects' cognitive functions and abilities for occupational participation were analyzed using the descriptive statistics produced by the SPSS 20.0 program. In addition, Pearson correlation coefficient was used to analyze the correlations between the cognitive functions of the subjects and their abilities for occupational participation. The results of the study showed positive correlations between cognitive function and the ability for occupational participation of patients with mild and moderate dementia. Based on the results of this study, the evaluation of the patients with dementia and ability for occupational participation related to the cognitive function in establishing the therapeutic goal should be considered.

Objective : The purpose of this study is to consider the change of hand function according to the quality of sleep and to find out a correlation among the quality of sleep and hand function, and sleep disturbing factors. Method : 23 patients who were hospitalized more than 6 months from Nov. 2017 to Jan. 2018 were tested for the quality of sleep used by sleep quality scale, for the grip strength used by a dynamometer, and for the coordination used by BBT and 9-Hole Peg test. The collected data were analyzed to implement the paired t-test and Pearson correlation coefficient. Result : In the high grade group of sleep score, the quality of sleep & BBT, and the grip strength & BBT have correlated each other; and in the medium group, only the latter has shown a correlation. In both groups, the quality of sleep and the sleep pattern have showed significant high correlation. Conclusion : When the elderly in geriatric hospitals show qualitative differences, BBT and the combination of treatment for the improvement of grip strength can improve the quality of sleep. And the sleep pattern intervention is considered to be effective to improve the quality of sleep.

This study analyzed the effect of meteorological factors on the concentration of PM10 (particulate matter 10) in the atmosphere and the variation of rainwater quality using multivariate statistical analysis. The concentration of PM10 in the atmosphere was continuously measured during eleven precipitation events with a custom-built PM sensor node. A total of 183 rainwater samples were analyzed for pH, EC (electrical conductivity), and water-soluble cations (Na+, Mg2+, K+, Ca2+, NH4+) and anions (Cl-, NO3-, SO42-). The data has been analyzed using two multivariate statistical techniques (principal component analysis, PCA, and Pearson correlation analysis) to identify relationships among PM10 concentrations in the atmosphere, meteorological factors, and rainwater quality factors. When the rainfall intensity was relatively strong (> 5 mm/h, rainfall type 1), the PM10 concentration in the atmosphere showed a negative correlation (r = -0.55, p < 0.05) with cumulative rainfall. The PM10 concentration increased the concentration of water-soluble ions (r = 0.25) and EC (r = 0.4), and decreased the pH (r = -0.7) of rainwater samples. However, for rainfall type 2 (< 5 mm/h), there was no negative correlation between the PM10 concentration in the atmosphere and cumulative rainfall and no statistically significant correlation between the PM10 concentration in the atmosphere and rainwater quality.

This study examined the relationships among levels of knowledge, attitude and preventive behavior regarding tuberculosis in service workers. The survey period was 1 - 7 October, 2015 with service workers who work in large scale stores in Jeonnam. The collected data were analyzed using an independent t-test, ANOVA, and Pearson's correlation coefficients using the SPSS WIN 12.0 program. The mean score for knowledge about tuberculosis was $14.05{\pm}6.39$, the mean score of attitude toward tuberculosis was $29.87{\pm}4.89$ and the mean score of preventive behavior for tuberculosis was $31.44{\pm}4.86$. Preventive behavior was found to have significant relationships with gender, marital status, smoking, job satisfaction, and subjective health status. A slightly positive correlation was observed between the knowledge of tuberculosis and the attitudes toward tuberculosis. A positive correlation was noted between the attitude toward tuberculosis and preventive behavior for tuberculosis, while there was a negative correlation between the preventive behavior and age. Therefore, is necessary to consider the related factors for the development and implementation of systematic education programs that can encourage and promote preventive behavior for tuberculosis among service workers.

This study aims to identify the mediating effect of school satisfaction in the effect of self-esteem on resilience, and to examine the relationship between brain function quotient and resilience. In this descriptive study, questionnaires and brainwaves were collected from 145 female high school students in Seoul from November 22 to December 23, 2012. Data were analyzed by Pearson's correlation coefficient and three-step mediated regression analysis using SPSS 21.0. Among brain function quotients, stress resistance quotient were highly correlated with resilience, and both attention and brain quotient were significantly correlated with resilience. Moreover, school satisfaction showed the mediating effect in the effect of self-esteem on resilience. The findings suggest that brain function quotient, in specific, stress resistance quotient, should be considered in studies regarding resilience. Furthermore, predictor variables of resilience such as self-esteem and school satisfaction should be considered for preventive and therapeutic intervention to reduce various maladaptive problems in adolescents.
