The purposes of this study were to provide information on the prevalence and change of Korean adolescent alcohol use and to identify related factors to adolescent alcohol use. This study collected data from a total of 4,373 adolescents nationally. Followings are the major findings of this study. First, 75.7 percent of respondents reported that they tried alcohol in their life time. More male respondents tried alcohol in their lifetime than female respondents, but there was no big difference. Findings on alcohol consumption by grade showed that as adolescents get older, they are more likely to try alcohol. Second, this study also found that whereas the drinking rates of male adolescents and higher graders were steady, the rates of female adolescents and lower graders were increased since 1997. Third, this study compared its findings with adolescent alcohol use in the United States. Little differences existed in measures of adolescent alcohol use in the two countries, but the differences in the rates of the past-month alcohol use and heavy drinking was greater in Korean adolescents than in American adolescents. Finally, this study found that peer related factors such as friend's alcohol use was the strongest factor related to respondents' alcohol use. Family-related factors and respondents' levels of psychosocial resources (cognitive control, coping skills, social support) were also significantly related to their alcohol use. This study suggest that future studies consider cultural aspects and regional differences in order to understand adolescent alcohol use in more depth.

In this article we describe our preliminary work to create VR interactive storytelling particularly for building empathic relationships between the reader (or the player) and story characters. As a practical guideline for developing empathy-based VR interactive story, we propose four key factors: first, narrativity considering narrative theories and concepts including the notion of focalization by Gerald Genette; second, interactivity for balancing between narrative and player control in interactive storytelling domain; third, consideration of virtual reality in human computer interaction domain; fourth, empathy in narrative from the viewpoint of psychology and cognitive science. We also introduce an example interactive storytelling scenario based on Little Red Riding Hood story. Finally we conclude with our VR implementation using Unreal game engine and HTC Vive.

The critical thinking has become gradually important in nursing education for the era of convergence. The literature review was undertaken to identify the study trends of critical thinking in nursing education in Korea. 75studies from 1996 to 2014 were reviewed. The studies related to critical thinking were highly increased from 2006. The study design was identified descriptive studies to path model. The predictors to critical thinking were an academic system, age, interpersonal relationship, academic achievement, the duration of clinical practice, satisfaction on nursing, self-esteem, self-efficacy, learning methods and so on. The consequence variables were clinical practice stress, cognitive stress, the ability of problem-solving, clinical competency, emotion control, communication competence. It is necessary to develop education programs and curriculum based on evidence from the researches for increasing critical thinking.

Objectives : This study investigated the differences of working memory among the subtypes of ADHD. Methods : Eighty-one children and adolescents with ADHD and thirty normal controls were recruited. Children with any cognitive disorders and low intelligence were excluded. In order to evaluate the verbal and visuospatial working memory, Digit span and Finger windows tasks were measured, respectively. Performances on these measures between children with ADHD and controls were compared. Further, performances among the groups of ADHD predominantly inattentive(ADHD-IA)(n=40), predominantly hyperactive-impulsive(ADHD-HI)(n= 10), and combined type(ADHD-C)(n=31), were compared. Results : Scores of Finger windows forward task were lower in the ADHD group as compared to the control group, whereas, the Digit span forward showed no difference. Both scores of Digit span backward and Finger windows backward task were lower in the ADHD group than the controls. Children with ADHD-IA performed poorer than children with ADHD-C on the Finger windows backward task. Conclusion : The results of this study showed that children with ADHD have deficits in spatial short-term memory and verbal and visuospatial working memory when compared to normal children. The deficits were evident in children with ADHD-IA subtype and in particular, performance on the visuospatial working memory task in this group was poorer than the ADHD-C group.

The main purpose of this study is to get insight into the essential cognitive basis of local food purchase behavior based on Ajzen's (1991) theory of planned behavior. By asking open-ended questions using an online survey, participants' (n=163) salient behavioral, normative, and control beliefs in regard to local food purchase were assessed and analyzed. The most salient advantage was supporting local economy, followed by freshness, knowledge of where the food came from and how it was handled, environmental benefits, and health benefits. Assessing to consumers' normative beliefs found that local businesses, local farmers, family, local people, and friends were the most frequently mentioned individuals or groups who would approve consumers' local food purchasing. In contrast, the most salient barrier was inconvenient store location and time, followed by higher prices, limited availability and variety, and limited knowledge about where to buy local food.

Purpose: Although innovative interventions using technologies have been introduced in long-term care settings, available evidence is still anecdotal. The purpose of this study is to investigate and synthesize the outcomes of interventions using technologies delivered to nursing home residents. Methods: Published clinical trials were identified through PubMed, CINHAL, Cochrane and PsycINFO databases and manually hand-searching. Eligible studies were articles published between 1997-2016 in English or Korean with a randomized controlled trial or quasi-experimental design in which interventions using technologies were delivered to nursing home residents. Results: A total of 20 studies were selected for this review. Types of interventions using technologies were classified into the electronic documentation technology (n=1), the clinical decision support system (n=1), the safety technology (n=1), the health and wellness technology (n=10), and the social connectedness technology (n=7). Overall resident outcomes indicated that interventions using technologies improved behavioral symptoms and psycho-social outcomes, but mixed results were shown in the aspects of physical function, cognitive function, social relationship and quality of service. Conclusion: This review demonstrates that incorporating technologies into nursing home care have positive effects on residents' psycho-social outcomes and behavioral symptoms. To disseminate the effectiveness of interventions using technologies, further research is needed to determine what mechanisms underlying such relationships exist.

Objectives: To evaluate the risk of fractures related with zolpidem in elderly insomnia patients. Methods: Health claims data on the entire South Korean elderly population from January 2005 to June 2006 were extracted from the Health Insurance Review and Assessment Service database. We applied a case-crossover design. Cases were defined as insomnia patients who had a fracture diagnosis. We set the hazard period of 1 day length prior to the fracture date and four control periods of the same length at 5, 10, 15, and 20 weeks prior to the fracture date. Time independent confounding factors such as age, gender, lifestyle, cognitive function level, mobility, socioeconomic status, residential environment, and comorbidity could be controlled using the case-crossover design. Time dependent confounding factors, especially co-medication of patients during the study period, were adjusted by conditional logistic regression analysis. The odds ratios and their 95% confidence intervals (CIs) were estimated for the risk of fracture related to zolpidem. Results: One thousand five hundred and eight cases of fracture were detected in insomnia patients during the study period. In our data, the use of zolpidem increased the risk of fracture significantly (adjusted odds ratio [aOR], 1.72; 95% CI, 1.37 to 2.16). However, the association between benzodiazepine hypnotics and the risk of fracture was not statistically significant (aOR, 1.00; 95% CI, 0.83 to 1.21). Likewise, the results were not statistically significant in stratified analysis with each benzodiazepine generic subgroup. Conclusions: Zolpidem could increase the risk of fracture in elderly insomnia patients. Therefore zolpidem should be prescribed carefully and the elderly should be provided with sufficient patient education.

Male rats aged 15 months, which had been over-trained with 12 arm radial maze up to the criterion of 1 or 2 errors an average per trial, were divided into two groups and 7 months after the over-training and were studied the effect of red ginseng trial saponin fraction (PT) on the spatial memory function. The rats which could be improved the performance of 9.75$\pm$1.26 (within 185$\pm$8.2 1 sec) were classified into "normal group" (n=4) and the ones, which showed R-maze performance of 7.0$\pm$2.87 within 300 sec, "deteriorated memory group" (n=5). PT was dissolved in distilled water and injected into the deteriorated memory group intraperitoneally at 30 min before R-maze for 3 consecutive days. The injected amount of PT on the 1st day was 10mg/rat, 1mg/rat both on the 2nd the 3rd day. As results, the performance was restored to 9.4$\pm$2.0 after stopping ginseng administration, although the lower performance values (1.4$\pm$0.89, 2.8$\pm$0.83, 3.8$\pm$0.84, respectively) were exerted during the three days of PT administration than before PT administration (7.0$\pm$2.87) since 1 day after administratitan of PT. The restored performance values were continuously maintained up to the level of the "normal group". However, any lower performance values were not observed when PT was administered via intraperitoneal route to the normal group in about of 2 mg/rat except 10mg1ra1. The number of errors when the foods in arms were put at only 6 places was clearly reduced during the 9 days of consecutive administration of PT as compared with untreated control. These results indicated that PT administration may enhance their cognitive function after a long lapse of time not only in the memory deteriorated rats but also in normal ones. The reason exerted lower performance values during PT administration in this paper was discussed as compared with the results of T-maze behavior of another 3-month-aged rats. of another 3-month-aged rats.

This is a primitive experimental study to find effects of 10 times classwide peer tutoring on academic achievement, self-leadership and interpersonal ability of nursing students. According to the results of Mann-Whitney U and Kruskal-Wallis test using SPSS/WIN 19.0, the motive of admission was the factor affecting the most mean ranks related to general characteristics. There were significant differences between academic achievements, cognitive strategy, and promoting relationships(p<.001; p=.020; p=.040), and there was a positive correlation between self-leadership and interpersonal ability(r=.296, p=.041) in Wilcoxon Signed Ranked test. As results of this study, the classwide peer tutoring could be applied in nursing classes for enhancing students' competence, but the researcher suggests further researches with wider range of subjects and setting control group.

In order to diagnose and prevent Alzheimer's Disease (AD), it is becoming increasingly important to develop a CAD(Computer-aided Diagnosis) system for AD diagnosis, which provides effective treatment for patients by analyzing 3D MRI images. It is essential to apply powerful deep learning algorithms in order to automatically classify stages of Alzheimer's Disease and to develop a Alzheimer's Disease support diagnosis system that has the function of detecting hippocampus and CSF(Cerebrospinal fluid) which are important biomarkers in diagnosis of Alzheimer's Disease. In this paper, for AD diagnosis, we classify a given MRI data into three categories of AD, mild cognitive impairment, and normal control according by applying 3D brain MRI image to the Faster R-CNN model and detect hippocampus and CSF in MRI image. To do this, we use the 2D MRI slice images extracted from the 3D MRI data of the Faster R-CNN, and perform the widely used majority voting algorithm on the resulting bounding box labels for classification. To verify the proposed method, we used the public ADNI data set, which is the standard brain MRI database. Experimental results show that the proposed method achieves impressive classification performance compared with other state-of-the-art methods.
