This research was designed to illuminate that work domains and family domains are not separated but interacting spheres and to suggest efficient coping strategies than alleviate work/family role conflicts. The subjects of this study were 395 employed professional wives living in Seoul. Korea. Survey methods were questionnaires. Data analysis strategies were percentile, frequency, one-way-anova and multiple classification analysis. The results were as follows; 1)Employed wives experienced time-based conflicts and strain-based role conflicts. This finding supports the scarcity approach that multiple roles inevitably create strain. 2) Individual, family and work-related variables were predictors of work/family role conflicts. This findings indicate that work domains and family domains cannot be regraded as separated spheres. 3) Employed wives tried to meet all the given roles demands not by reducing role responsibilities, but by increasing the efficiency of role performance. This finding reflects the characteristics of employed wives who try to perform successfully all the responsibilities. 4)The negative correlation of coping strategies and work/family role conflicts suggests that strategies can function effectively in alleviating the work/family role conflicts.

A technique of finding both probability density and distribution function for interkilling times is considered and demonstrated. An important result is that any arbitrary interfiring time random variables fit to this study, The interfiring renewal density function given a certain interfiring probability density function can be applied to obtain the corresponding interkilling renewal density function which helps us to estimate the expected number of killing events in a time period. The numerical inversion of Laplace transformation makes these possible and the results appear to be excellent. In case of ammunition supply is limited, an alternative way of getting the probability density function of time to the killing is investigated. The convolution technique may give us a means of settling for this new problem.

This paper focuses on finding out visualization process by means of VTA(Visual Task Analysis) of expert teachers' simple task. Findings indicate teachers have coding schema of performing visual task as such; (a) the analyzing by reading and some activities in the task text, (b) conceptualizing or understanding in his/her own way, (c) the explaining of the action or product, (d) the searching by thinking or finding, (e) the decision of visualizing of the task. Expert teachers tried to visualize in the form of abstract graph, and to omit the object which was not directly related to the topic at the pilot study. VAT based on ground theory and protocol analysis was developed and performed. This case study suggests that an additional study for searching a guide and method might be beneficial for conducting a visual task analysis.

Instagram is one of the fastest-growing online photo social web services where users share their life images and videos with other users. Image tagging is an essential step for developing Automatic Image Annotation (AIA) methods that are based on the learning by example paradigm. Hashtags can be used on just about any social media platform, but they're most popular on Twitter and Instagram. Using hashtags is essentially a way to group together conversations or content around a certain topic, making it easy for people to find content that interests them. Practically on average, 20% of the Instagram hashtags are related to the actual visual content of the image they accompany, i.e., they are descriptive hashtags, while there are many irrelevant hashtags, i.e., stophashtags, that are used across totally different images just for gathering clicks and for search ability enhancement. Hence in this work, Sorting instagram hashtags all the way through mass tagging using HITS (Hyperlink-Induced Topic Search) algorithm is presented. The hashtags can sorted to several groups according to Jensen-Shannon divergence between any two hashtags. This approach provides an effective and consistent way for finding pairs of Instagram images and hashtags, which lead to representative and noise-free training sets for content-based image retrieval. The HITS algorithm is first used to rank the annotators in terms of their effectiveness in the crowd tagging task and then to identify the right hashtags per image.

This study was conducted to understand the factors influencing happiness of college students while focusing on meaning in life and to supply an interventional way for promotion of happiness of college students. The subjects were 205 students in C city and the data were collected from 20-30 October 2016. Data were analyzed based on themeans using an independent t-test, ANOVA, $Scheff{\acute{e}}^{\prime}s$ method, Pearson's correlation coefficients and stepwise multiple regression. Significant differences were found in the happiness grades by sex (p=0.045), age (p=0.019), degree (p=0.038), satisfaction in major (p<0.001), and perceived health condition (p<0.001). Happiness was positively related to self-confidence (p<0.001), self-control (p<0.001), positive emotion (p<0.001), meaning in life (p<0.001), finding meaning in life (p<0.001), and search for meaning in life (p<0.001). Uponmultiple regression analysis, finding meaning in life, perceived health condition, and satisfaction withmajor accounted for 41.0% of the happiness, with finding meaning in life beingthe most influential factor.

This study examined the relationship between marital cohesion adaptability and marital communication and especially tested the linear versus curvilinear hypothese with Circumplex Model. The subjects were 142 couples living in Pusan./ The data were analyzed using frequency one-way ANOVA and Pearson's correlation coefficient The major finding of this study were as follows: The relationship between the dimensions of cohesion adaptability and communica-tion was linear than curvilinear. High cohesion and high adaptability spouses were more effective communication than low cohesion and low adaptability.

The orientation space representation is constructed by treating the orientation parameters, which Gabor filters can be turned, as a continuous variable. The problem of multiple orientation line segmentation is dealt with by thresholding 3D images of the orientation space and then detecting the connected components therein. In this way, X-junctions and T-junctions are able to be separated effectively. Experimental results are presented using synthesized image.

There is a deep and useful connection between thermodynamics (the behavior of systems with many degrees of freedom in thermal equilibrium at a finite temperature) and combinational or continuous optimization (finding the minimum of a given multiparameter function). At the heart of the method of simulated annealing is an analogy with the way that liquids freeze and crystallize, or metals cool and anneal. This paper provides a detailed description of simulated annealing. Although computationaly intensive, when it is carefully implemented, simulated annealing is found to give superior results to more traditional methods of nonlinear optimization.

One of the most popular graphical techniques for goodness of fit problems is the quantile-quantile plot(Q-Q plot) Easton and McCulloch(1990) suggested a way of generalizing Q-Q plots to multivariate cases bases on finding a matching between the points of the data set whose shape is being examined and a reference sample. in this paper we investigated the asymptotic behavior of the generalized Q-Q plot for bivariate cases. As a result we concluded that the standard univariate Q-Q plot and the generalized Q-Q plot have the same limit if two variables are independent.

When top down method is used, it could be a construction method trouble in column joint, between the former concrete and the latter. It could bring a void and weak concrete in column. The purpose of this study is finding a way to prevent concrete void and concrete suitable for top down, through V-metering for top down column and concrete experiment.
