Purpose: To evaluate the influence of experiences of witnessing tobacco advertising and preferences of tobacco companies' social responsibility (CSR) on current and future smoking intentions in adolescents. Methods: Data were collected from 700 adolescents living in Korea representing 7 metropolitan cities and 8 provinces in the method of proportional random sampling. The Gallup's data collection system was adopted using 1:1 face to face interviews. The witness of tobacco advertising was determined by 'yes', or 'no' responses to three survey items and to four survey items for preferences of tobacco CSR. For statistical analysis, ${\chi}^2$ test, Fisher's exact test and logistic regression were used. Results: 98.4% of the adolescents had experiences of witnessing tobacco advertising. POP (OR=103.44, 95% CI: 8.22~1301.45) and magazine advertisement (OR=6.07, 95% CI: 1.34~22.58) had a significant effect on their current smoking. Also, POP (${\beta}$=.24, p<.001) and movie advertisement (${\beta}$=.42, p<.001) had a significant effect on their future smoking intentions. As for the preferences of tobacco CSR, cultural-art support activities (${\beta}$=.15, p=.025) and environmental purifying campaigns (${\beta}$=-.15, p=.034) had a significant effect on their future smoking intentions. Conclusion: Witness of tobacco advertising and positive responses to tobacco CSR are associated with current and future smoking intentions in adolescents.

In this paper, we study the effects of long-range dependence (LRD) in VBR video traffic on queueing system. This paper consists of Part I and II. In Part I, we present a (LRD) video traffic model based on the shifting-level (SL) process. We observe that the ACF of an empirical video trace is accurately captured by the shifting-level process with compound correlation (SLCC): an exponential function in short range and a hyperbolic function in long range. We present an accurate parameter matching algorithm for video traffic. In the Part II, we offer the queueing analysis of SL/D/1/K called ‘quantization reduction method’. Comparing the queueing performances of the DAR(1) model and the SLCC with that of a real video trace, we identify the effects of SRD and LRD in VBR video traffic on queueing performance. Simulation results show that Markoivian models can estimate network performances fairly accurately under a moderate traffic load and buffer condition, whereas LRD may have a significant effect on queueing behavior under a heavy traffic load and large buffer condition.

Inundation of substation and ground power equipment breaks out every summer season in low-lying downtown and low-lying shore by localized heavy rain, typhoon and tidal wave. In case inundation excluding the exchanging cost of equipment, it occurs a great economic and social loss owing to recovery time and events of electric shock occur by inundation electrical equipment(Pad-mounted Transformer and Switch). In case of installing the power equipment at flood danger territory, we are necessary to the product development, the product is that water does not come in the inside the power equipment. Product of pressure maintaining are established on the basic frame and sensor operates at the flooding occurrence and is maintained a shutting tightly structure and it is a method. The product which is produced the reliability of the product it confirmed a flooding yes or no from the condition which puts in the water tank and it verified. We estimate that loss cost which is caused by with flooding and the power failure will be diminished if it is addition to advances the reliability evaluation and a security of the flood protection product.

In recent years, Shield TBM construction has been continuously increasing in domestic tunnels. The main excavation tool in the shield TBM construction is a disc cutter which naturally wears during the excavation process and significantly degrades the excavation efficiency. Therefore, it is important to know the appropriate time of the disc cutter replacement. In this study, it is proposed a predictive model that can determine yes/no of disc cutter replacement using machine learning algorithm. To do this, the shield TBM machine data which is highly correlated to the disc cutter wears and the disc cutter replacement from the shield TBM field which is already constructed are used as the input data in the model. Also, the algorithms used in the study were the support vector machine, k-nearest neighbor algorithm, and decision tree algorithm are all classification methods used in machine learning. In order to construct an optimal predictive model and to evaluate the performance of the model, the classification performance evaluation index was compared and analyzed.

This study was conducted to provide the basic information for nursing intervention in infant teach. ing and feeding situation. The subjects were 30 pairs of mother and her infant(9 month) who were normally delivered at 3 university hospital in Seoul area. The data collection was conducted by observation using videotaperecord from September 27, 1989 to Feburary 26, 1990 in their home. The measulsement tools used by this researcher were Nursing child Assessment Teaching scale (NCATS) and Nursing child Assessment Feeding Scale(NCAFS) which was developed by Barnard. The higher sum of "yes" score means the higher mother-infant interaction level. Mother-Infant interaction behaviors in both sitution were based on 6 subcategories; sensitivity to cue, response to distress, social-emotional growth fostering, cognitive growth 'fostering, clarity of + cues, and responsiveness to parent. The data collected through above method were analyzed by mean and t-test and the results were as follows. 1. The sum of maternal behavior score was 40.2 out of 50.0 in teaching situation and 37.9 out of 50.0 in feeding situation. Out of the 4 subcategories on maternal behavior in both situation, the highest subcategory was shown by response to infant's distress and the lowest subcategory by cegnitive growth fostering. 2. The sum of infant behavior score was 14.7 out of 23 in teaching situation and 17.9 out of 26 in feeding situation. Out of the 2 categories on infant behavior in both situation, the highest sub categroy was shown by the clarity of infant's cue in both situation. 3. There was a statistical significance between father's educational level and mother-infant interaction in teaching situation; college group was higher than high school group, particulary in category of sensitivity to infant's cue and congnitive growth fostering. 4. There was a statistical significance in teaching situation between mother's educational level and mother-infant interaction;college group was higher than high school group, particulary sensitivity to infant cue, social-emotional growth fostering and cognitive fostering. 5. There was no statistical difference in between parent educational level and mother.infant interaction in feeding situation.situation.

GuessWhat?! is a game in which two machine players, composed of questioner and answerer, ask and answer yes-no-N/A questions about the object hidden for the answerer in the image, and the questioner chooses the correct object. GuessWhat?! has received much attention in the field of deep learning and artificial intelligence as a testbed for cutting-edge research on the interplay of computer vision and dialogue systems. In this study, we discuss the objective function and characteristics of the GuessWhat?! game. In addition, we propose a simple solver for GuessWhat?! using a simple rule-based algorithm. Although a human needs four or five questions on average to solve this problem, the proposed method outperforms state-of-the-art deep learning methods using only two questions, and exceeds human performance using five questions.

Purpose: This study aimed conducted to investigate biomedical ethics awareness and attitudes toward dignified death and advance directives among nursing students. Methods: Data were collected through structured questionnaires from 222 nursing students with clinical practice experience, from November 7 to 23, 2015. Data were analyzed by independent t-tests, one-way ANOVA, Kruskal-Wallis test, and Pearson's correlation coefficients using SPSS WIN 22.0. Results: The scores for biomedical ethics awareness and attitudes toward dignified death were 2.89 and 3.15, respectively. Regarding attitudes toward advance directives (ADs), most students agreed with writing ADs. The main reason given for writing ADs is "I want to receive my treatment of choice." As for the range and explanation method for ADs, 45.7% of participants responded, "do not know well." Regarding willingness toward life sustaining treatment, "only pain control, no life sustaining treatment" was indicated by 83.4% and, "all information about symptoms and prognosis" by 91.9% of participants. For willingness to write ADs, 70.0% of participants responded "yes." Conclusion: Curriculum for nursing ethics should be included in clinical training courses to improve related courses and provide an opportunity to deal with practical problems, such as biomedical ethics, death with dignity, and ADs.
