In this paper, we introduce XOnto-Apriori algorithm which is an extension of the Onto-Apriori algorithm. The extended algorithm is designed to improve the conventional algorithm's problem of comparing only identifiers of transaction items by reasoning transaction properties of the items which belong in the same category. We show how the mining algorithm works with a smartphone application recommender system based on our extended algorithm to clearly describe the procedures providing personalized recommendations. Further, our simulation results validate our analysis on the algorithm overhead, precision, and recall.

This study examined the effect of long-term care utilization on the health care utilization of Medicaid elderly. The subjects were 5,834 long-term care insurance with the level 1 Medicaid elders, who received either service or non-service. This study examined the impact of long-term care service on the probability of health care utilization and the costs of health care utilization. The total medical cost and inpatient day between 2009-2007 were significant factors affecting long-term care utilization (${\beta}=.29$, p< .001, ${\beta}=.33$, p< .001 ) and this variable explained 22.6% of the total medical cost and 22.4% of the inpatient day. The results showed that non-service in long-term care was associated with an increase in health care utilization. The current long-term care insurance system should place higher priority and more resource allocation on long-term care utilization to increase the efficiency of the insurance system.

This study is to form develops an effective teaching method centered on the Korean "symbol adverb + predicate" type, helping Chinese students to learn Korean to communicate more accurately when expressing detailed complex feelings and various emotions.Manyforeignlanguage learners try to memorize individual words when they acquire the new vocabulary, this may lead to a problematic in that they cannot use Korean vocabulary accurately and naturally because they do not value the combination of vocabulary words. Since symbolic adverbs are not used in isolation and being frequently used with certain vocabulary words, it is more effective to teach them in the form of instruct learners using "symbol adverb + predicate" forms rather than individual vocabulary words. Accordingly, this research considers a particular vocabulary following symbolic adverbs or vocabulary groups with common semantic qualities that could be frequently introduced. Seven Korean language textbooks used by university in domestic Korea and China are compared and analyzed to reveal the aspects of differences in the use of descriptive words after symbolic adverbs. Finally, based on the textbook analysis results, the government propose a plan to improve the Korean "symbol adverb + predicate" type for Chinese learners. However, this study was limit to being unable to present specific educational measures for Chinese learners in the form of "symbol adverb + predicate". This is expected to complement the limitations of this study in subsequent studies, and lead to more specific discussions.

This is a quasi-experimental study involving one group design with pretest and posttest for evaluation of an effectiveness of an emergent care management simulation education among senior nursing students according to their learning styles. Participants were 58 senior nursing students. Learning style and educational effectiveness (critical thinking disposition, problem solving process, cooperation, satisfaction with learning, and self-confidence) were measured. Learning styles of senior nursing students were converger 46.6%, assimilator 34.5%, accommodator 15.5%, and diverger 3.4%. Critical thinking disposition, problem solving process, cooperation, and self-confidence were significantly enhanced by an emergent care management simulation education. Otherwise, educational effectiveness according to learning styles were not significantly different. Based on the results, devising stratagem to maximize an educational effectiveness will be needed trough re-evaluation of relationship between learning styles and effectiveness of a simulation education.

This is a descriptive correlation study to identify job stress, fatigue, and depression among ship-building supply workers. The subjects were 175 ship-building supply workers at one small & medium-sized ship-building supply company in K city. The data were collected from February 1st throughout 28th, 2013. The collected data were analyzed using the SAS program through mean, standard deviation, and Pearson's correlation coefficients. There was a positive correlation between job need and job insecurity of the job stress underlying factors and fatigue respectively (r=0.15, p<.05; r=0.17, p<.05). There was a negative correlation between organizational system factor and fatigue (r=-0.19, p<.05). Also there was a positive correlation between workplace culture factor and depression (r=0.15, p<.05). In conclusion, it could be needed for organizational managers to develop strategies for improving the workers' psychosocial workplace environment.

Since 1990s, more and more enterprises outsource the logistics to reduce the cost and improve core competence, which bring the prosperity of 3PL, industry in China. However, some data shows that the service quality of 3PL is not good enough, there is only a few companies that can provide systematic service, and the satisfaction of the customer is very low. Besides, many enterprises choose 3PL service provider mainly based on the price. Although there are many papers on the logistics service quality, they mainly research on single part, Studies on the relation between the service quality and the partnerships of outsourcing are scarce. Therefore, this study tries to research the service quality, partnership and the relationship between them in China's 3PL industry systematically. On the foundation of the service quality and partnership theories by former researchers, taking present situation of China's 3PL industry into consideration, this paper constructs service quality and the partnership evaluation system and develops LSQ-PP model to examine the relation between the service quality and partnership. and then use the Structural Equation Model (SEM) to analysis the full sample of collected questionnaires. Finally, the thesis summarizes the conclusion and offers suggestions for practice and future research.

Integration analysis of multi-sensor satellite images is becoming increasingly important. The first step in integration analysis is image registration between multi-sensor. SIFT (Scale Invariant Feature Transform) is a representative image registration method. However, optical image and SAR (Synthetic Aperture Radar) images are different from sensor attitude and radiation characteristics during acquisition, making it difficult to apply the conventional method, such as SIFT, because the radiometric characteristics between images are nonlinear. To overcome this limitation, we proposed a modified method that combines the SAR-SIFT method and shape descriptor vector DLSS(Dense Local Self-Similarity). We conducted an experiment using two pairs of Cosmo-SkyMed and KOMPSAT-2 images collected over Daejeon, Korea, an area with a high density of buildings. The proposed method extracted the correct matching points when compared to conventional methods, such as SIFT and SAR-SIFT. The method also gave quantitatively reasonable results for RMSE of 1.66m and 2.45m over the two pairs of images.

This paper explains the hardware structure of SURF(Speeded Up Robust Feature) based feature point extractor and its FPGA verification result. SURF algorithm produces novel scale- and rotation-invariant feature point and descriptor which can be used for object recognition, creation of panorama image, 3D Image restoration. But the feature point extraction processing takes approximately 7,200msec for VGA-resolution in embedded environment using ARM11(667Mhz) processor and 128Mbytes DDR memory, hence its real-time operation is not guaranteed. We analyzed integral image memory access pattern which is a key component of SURF algorithm to reduce memory access and memory usage to operate in c real-time. We assure feature extraction that using a Vertex-5 FPGA gives 60frame/sec of VGA image at 100Mhz.

The present paper considers lice described in some premodern Korean proses, focused on the implications of lice and the literary strategies adopted by the writers in dealing with this unique subject matter. The works reviewed in this process are "A Story of the Louse and the Dog" by Lee Gyu-bo (Goryeo Dynasty), "The Old Man's Vindication of Lice" by Gwak Yeol (Early Joseon), "A Small Realization" by Yu Sin-hwan (Late Joseon) and "Miscellany" by Heo Jeon (Late Joseon). In these premodern essays, an allegory of lice was used to disclose various kinds of prejudices that people generally had: against things small (in "A Story of the Louse and the Dog"), against the old (in "The Old Man's Vindication of Lice"), against the dichotomous idea of right and wrong (in "A Small Realization") and against various aspects of life (in "Miscellany").
