The education effect of environmental impact cognitive instruction on high school students was investigated. Environmental values of students could be classified into egocentric, social-altruistic and biospheric values like those of Schultz’s three kinds of categories. The value distribution of students consists 44.7% of egocentric and biospheric value groups and 12.5% of social-altruistic value group, respectively. The environmental function such as knowledge and skill did not show remarkable differences between value groups. The environmental value only affected the attitude function. The biospheric value group had the higher attitude function than other value groups. The environmental impact cognitive instruction enhanced the environmental functions irrespective of the value group or instruction type. However, significant variables were different according to environmental functions. Environmental functions such as knowledge and skill were influenced by the instruction itself. The attitude function was dependent on instruction itself, value type and instruction type. The optimum application of the environmental impact cognitive instruction can be efficiently achieved through class division into egocentric value group and biospheric value group. Alternatively, the proper combination of instruction methods focused biospheric and egocentric impacts in a class can be recommended.

Purpose: As population of elderly people continues to grow, successful aging has risen to the top of the nursing science agenda. The successful aging includes maintenance of the cognitive and physical functions, as well as emotional well-beings. This study was carried out to evaluate effects of the environmental enrichments on cognition of institutionalized elderly. Method: The population was selected among the elderly aging over 65 residing at two of institutions. A quasi experimental design was used with non-equivalent control group. Study subjects were thirteen for each group. For the experimental group, physical, social and symbolic environmental enrichment program was provided for six weeks. The data were analyzed by repeated measure ANOVA and repeated measure ANCOVA using SPSS Win 11.0. Result: Compared to control group, the experimental group showed a significant difference on DSF(F=3.29, p=.046), and TMTA(F=4.76, p=.013) of cognitive function, and depression (F=5.56, p=.007) of emotional distress after 1 and 12 weeks of environmental enrichment program. Conclusion: Findings indicate that physical, social, and symbolic environmental enrichment was effective to partially prevent from cognitive decline, and to decrease emotional distress of elderly. As a nursing intervention, environmental enrichment program for elderly should be expanded for nursing practice to promote healthy aging and to offer support to the growing population of elderly. Further research should be conducted to evaluate the effect on the community elderly.

With the increasing number of the wireless and mobile networks, the way that people use the Internet has changed substantively. Wireless multimedia services, such as wireless video streaming, mobile video game, and mobile voice over IP, will become the main applications of the future wireless Internet. To accommodate the growing volume of wireless data traffic and multimedia services, cognitive radio (CR) and Information-Centric Network (ICN) have been proposed to maximize the utilization of wireless spectrum and improve the network performance. Although CR and ICN have high potential significance for the future wireless Internet, few studies have been conducted on collaborative operations of CR and ICN. Due to the lack of infrastructure support in multi-hop ad hoc CR networks, the problem is more challenging for video streaming services. In this paper, we propose a Cross-layer Video Streaming Mechanism (CLISM) for Cognitive Radio Ad Hoc Information Centric Networks (CRAH-ICNs). The CLISM included two distributed schemes which are designed for the forwarding nodes and receiving nodes in CRAH-ICNs. With the cross-layer approach, the CLISM is able to self-adapt the variation of the link conditions without the central network controller. Experimental results demonstrate that the proposed CLISM efficiently adjust video transmission policy under various network conditions.

Purpose: The purpose of this study was to test a hypothetical model of chemotherapy-related cognitive impairment (CRCI) and depression in people with gastrointestinal cancer. Methods: A purposive sample of 198 patients undergoing chemotherapy was recruited from November 2014 to July 2015. The instruments were Everyday Cognition (ECog), Hospital Anxiety Depression Scale (HADS), Functional Assessment of Chronic Illness Therapy-Fatigue (FACIT-F), and M. D. Anderson Symptom Inventory-Gastrointestinal Cancer Module. Data were analyzed using descriptive statistics, correlation, and path analysis. Results: CRCI was directly affected by cancer symptoms (${\beta}=.19$, p=.004) and fatigue (${\beta}=.56$, p<.001)($R^2=47.2%$). Depression was directly affected by fatigue (${\beta}=.48$, p<.001) and CRCI (${\beta}=.27$, p<.001). However, The impact of cancer symptoms on depression was confirmed through the mediating effect of CRCI. Conclusion: Results indicate that in patients with gastrointestinal cancer undergoing chemotherapy along with the direct physiologic effects (fatigue, symptoms) of cancer treatment may have altered cognitive function leading to depression.

Cognitive radio (CR) is considered an attractive technology to deal with the spectrum scarcity problem. Multi-radio access technology (multi-RAT) can improve network capacity because data are transmitted by multiple RANs (radio access networks) concurrently. Thus, multi-RAT embedded in a cognitive radio network (CRN) is a promising paradigm for developing spectrum efficiency and network capacity in future wireless networks. In this study, we consider a new CRN model in which the primary user networks consist of heterogeneous primary users (PUs). Specifically, we focus on the energy-efficient resource allocation (EERA) problem for CR users with a special location coverage overlapping region in which heterogeneous PUs operate simultaneously via multi-RAT. We propose a two-tier crossover genetic algorithm-based search scheme to obtain an optimal solution in terms of the power and bandwidth. In addition, we introduce a radio environment map to manage the resource allocation and network synchronization. The simulation results show the proposed algorithm is stable and has faster convergence. Our proposal can significantly increase the energy efficiency.

Purpose: The purpose of this study was to investigate the effect of the moderate drinking program based on social cognitive theory on changes in the drinking habits of college students with drinking problems. Methods: This study included a total of 68 college students with drinking problems. These participants participated in 10 sessions of a moderate drinking program in which social cognitive theory was applied. Changes in the cognition and behaviors of the participants were then investigated. Results: The moderate drinking program based on social cognitive theory for college students with drinking problems was effective in increasing the subjects' drinking-related knowledge (U=191.50, p<.001), enhancing their drinking refusal self-efficacy(t=8.02, p<.001), and changing their drinking-related attitudes (U=108.50, p<.001), drinking outcome expectancy (t=8.68, p<.001), amount of drinking in a single session ($x^2=25.72$, p<.001), number of drinking sessions per month ($x^2=10.05$, p=.006), and problem drinking behaviors (t=5.77, p<.001). Conclusion: These results can be used to inform a regular on-campus intervention programs for moderate drinking, and to implement education about moderate drinking, thereby increasing the success rate of drinking reduction.

Objectives: Tic disorder is a neurodevelopmental disorder characterized by multiple involuntary movements of muscles or vocalization. Although tic symptoms subside as the patient ages, some patients suffer from significant functional impairments related to severe tic symptoms. This manuscript aimed to review the latest scientific evidences for the effect of cognitive-behavioral interventions on tic disorder. Methods: The relevant studies were identified by searching medical research databases. We focused our search on studies published between 2000 and 2020 in order to reflect the latest scientific evidence. A total of 821 articles were identified in the initial database search and 27 articles were finally included for the review after the exclusion of duplicated and irrelevant articles. Results: Behavioral therapies including habit reversal training, Comprehensive Behavioral Intervention for Tics, and exposure and response prevention were the most widely studied interventions for tic disorder and are recommended as first-line treatments for tic disorders with high confidence. Cognitive psychophysiologic approaches were also reported to be effective. Conclusion: Further studies are needed to support the future treatment of tics with low-cost and more widely available treatments, in order to ensure better treatment outcomes.
