연속형 분포로부터 얻은 독립적인 p값들을 통합하는 Fisher의 고전적인 방법은 널리 사용되고 있지만 이산형 확률분포로부터 얻은 p값들을 통합하기에는 적절하지 않다. 대신에 유사 Fisher의 통합방법이 이산형 확률분포의 p값들을 통합하는 대안으로 사용된다. 본 논문에서는 첫째, 여러 표본들의 위치검정(Fisher-Pitman 검정과 Kruskal-Wallis 검정) 데이터와 관련된 이산형 확률분포로 부터 퍼뮤테이션 방법에 의해 p값들을 구하고, 둘째로 이 p값들을 유사 Fisher의 통합방법을 이용하여 통합한다. 그리고 Fisher의 고전적인 방법과 유사 Fisher의 통합방법의 결과를 비교한다.

Recently, the concept of web site stickiness receives attention as a measure of strategy to influence user's visit and behavior on web sites. Web site stickiness means site visit frequency and stay duration. This study investigates the moderating effect of espoused national cultural values on Internet community stickiness with the assumption that dimensional values of national culture can be internalized as individual’s espoused values. Espoused values (i.e., espoused national cultural values) are defined as the degree to which an individual embraces the values of his or her national culture. Our findings can be summarized as follows. First, femininity and power distance moderate the influence of user participation on Internet community stickiness. Second, uncertainty avoidance and power distance moderates the effect of social influence on Internet community stickiness. However, femininity and collectivism do not moderate the effect of social influence on Internet community stickiness. Third, uncertainty avoidance, femininity, and collectivism moderate the influence of network effect on Internet community stickiness. Fourth, masculinity does not moderate the influence of usefulness on Internet community stickiness.

This study was conducted to investigate how the community values taught at home by parents affect the soundness of family life. The 914 participants in the sample were parents residing in Seoul. Major findings are described in the following: 1) The general level education of community-oriented values at home, which was measured by the level of parents' practice of community-oriented behavior, was very insufficient. 2) The soundness of family life was measured in six sub-areas. The six areas showed varying degrees of soundness, but the overall level of soundness was satisfactory. The conjugal relationship had the highest degree of soundness, whereas the general everyday atmosphere at home marked the lowest level. 3) The only significant independent variable that affected the practice of community values was the participants's subjective perception of their social class standing. 4) The level of practice of community values and social class variables were found to influence the soundness of family life. The level of practice of community values was an especially strong predictor in all areas of family soundness. In conclusion, the education of community values at home, measured by the parental practice of community-oriented behavior, positively influences the soundness of the family.

Environmental fate of ionizable organic pollutants such as perfluoroalkyl acids (PFAAs) are of increasing interest but has not been well understood because of uncertain values for parameters related with atmospheric interphase partitioning behavior. In the present study, not only the values for air-water partition coefficient (K_AW) and dissociation constant (pKa) of PFAAs were induced by adjusting to in situ measurements of air-water distribution coefficient between vapor phase and rainwater but also gas-particle partition coefficients were also estimated using three-phase partitioning model of ionizable organic pollutants, in situ measurements of PFAAs in aerosol and air vapor phase, and obtained parameter values. The pKa values of PFAAs we obtained were close to the minimum values suggested in literature except for perfluorooctane sulfonic acids, and COSMOtherm-modeled K_AW values were assessed to more appropriate among suggested values. When applying parameter values we obtained, it was predicted that air particle-associated fate and transport of PFAAs could be negligible and PFAAs could distribute ubiquitously along the transection from urban to rural region by pH-dependent phase transfer in air. Our study is expected to have some implications in prediction of the environmental redistribution of other ionizable organic compounds.

This research intends to observe the effects of social capital regarding fashion social enterprises on the community sense of participating consumers, and verify the relationship of the effects that such social capital and community sense have on sustainability formation variable(shared values, suitability of values, behavioral flow, cognitive belief and long-term relationship orientation) of social enterprises. For such analysis, a sample of 400 consumers with experience of purchasing products of fashion social enterprises more than once was utilized, and path analysis was conducted utilizing AMOS 20.0. As a result of this research, first, information sharing, social participation among the characteristic factors of social enterprises' social capital had a meaningful impact on shared values, and self-pursuit and significance meaningfully affected the suitability of values. Second, mutual influence, sense of belonging, satisfaction of needs and emotional bond among the characteristic factors of community sense between social enterprises and consumers meaningfully affected shared values, whereas mutual influence, sense of belonging and emotional bond substantially influenced suitability of values. Third, shared values and suitability of values affected the relationship between behavioral flow and cognitive trust, and behavioral flow and cognitive trust both had meaningful impact on long-term relationship orientation.

This study investigates the effects of clothing consumption values and subjective age on fashion adoption. To explain the fashion adoption of elderly women, 5 dimensional consumption values were adopted as explanatory factors, and subjective age is included as a moderating factor. This study tested the relationship of variables with survey data from a convenient sample of elderly women. A total of 235 complete responses were obtained from women between 50 and 71 years of age. The results are as follows. First, factor analysis on clothing consumption values resulted in 5 dimensional structures of consumption values for the sample (epistemic, symbolic, harmonic, popular, and practical values). A factor analysis on subjective age resulted in 2 dimensions (physical and mental age). Second, epistemic, popular, harmonic (-) and symbolic values (except practical value) significantly affected fashion adoption. Third, the epistemic value was the strongest factor regardless of physical and mental age but the effects of epistemic, popular, harmonic, symbolic, and practical values changed depending on the level of the moderating factor.

This study conducted to monitor decomposition process of the charomatophore pollution solution of an animal slurry by using a CCD camera. After the solution was put into test tube, the images(R, G, B, H, L, S) values of the solution were measured by the imgae processing system, and those of it\`s optical density were measured for three hours to be decomposed by microscopic organism. The values of measured for three hours to be decomposed by microscopic organism. The values of measured images(R, G, B, H, L, S) were analysed and compared with those of the optical density. Some of the results are as follows. 1. High correlation coefficients, which analyzed by using data on linear equations, were 0.9557 and 0.9672. They were decreased regularly in this R-value experiment of RGB level. The microscopic organism in this experiment was effective for decomposition of the red charomatophore pollution solution. 2. The values of all correlation coefficients from relationship between RGB-value and optical density were more than 0.95 except H-values. RGB-values, which were average values of summed R, G, B values, had correlation coefficients of 0.9863, 0.9937. These results showed so good relationship that decomposition process of charomatophore pollution solution could be monitored by a image processing system.

In this study, we discuss ways to environmental values education from sentences on environmental education textbooks. Values education is very important territory in environmental education. But school environmental education has some different idea about how to teach that. One way is to teach directly. The other way is to teach in a roundabout way. These days many researches said that roundabout way is better. The purpose of this study is to find out good ways to values education in environmental education. So we analyzed sentences on four environmental education textbooks of middle school. The analysis is limited body of textbooks. And we found immediate appropriateness expression for values education. The study results are as follows. There are 420 immediate expression in textbooks. That is 11% of whole expressions. And 6 big Units of textbooks have not difference about that expression. Most last sentences of class are immediate expressions. So authors of textbook will have mind about good values education method. One method is to use many interrogative sentences. Interrogative sentences help that student have values of themselves.

In the present study, iodine-131 S values (r_T ← thyroid) were calculated for 30 target organs and tissues using the most recently developed Korean reference computational phantoms. The calculated S values were then compared with those of the International Commission on Radiological Protection (ICRP) reference computational phantoms to investigate the dosimetric impact of the Korean S values against those of the ICRP reference phantoms. The results showed significant differences in the S values due to the different anatomical/morphological characteristics between the Korean and ICRP reference phantoms. Most target organs/tissues showed that the S values of the Korean reference phantoms are lower than those of the ICRP reference phantoms, by up to about 4 times (male spleen and female thymus). Exceptionally, three target organs/tissues (gonads, thyroid, and extrathoracic region) showed that the S values of the Korean reference phantoms are greater, by 1.5-3.7 times. We expect that the S values calculated in the present study will be beneficially used to estimate organ/tissue doses of Korean patients under radioiodine therapy.

Adopting Internet of Things (IoT)-based technologies in smart homes helps users analyze home appliances electricity consumption for better overall cost monitoring. The IoT application like smart home system (SHS) could suffer from large missing values gaps due to several factors such as security attacks, sensor faults, or connection errors. In this paper, a novel framework has been proposed to predict large gaps of missing values from the SHS home appliances electricity consumption time-series datasets. The framework follows a series of steps to detect, predict and reconstruct the input time-series datasets of missing values. A hybrid convolutional neural network-long short term memory (CNN-LSTM) neural network used to forecast large missing values gaps. A comparative experiment has been conducted to evaluate the performance of hybrid CNN-LSTM with its single variant CNN and LSTM in forecasting missing values. The experimental results indicate a performance superiority of the CNN-LSTM model over the single CNN and LSTM neural networks.
