  • The purpose of this study was to analyze the within-group verbal interaction according to leader's personality in Thinking Science activities. For this study, 2 homogeneous small groups by cognitive level selected from one class of sixth grader. Each group was comprised of four students. Leaders of two groups selected from the results of NEO personality assessment and teacher's observation. One who got high scores in extraversion and agreeableness is named a sociable leader, the other who got low scores in extraversion and agreeableness is named a taciturn leader. Verbal interactions during small group activities were audio/video taped and students' interactions were classified into on-task and off-task. On-task included cognitive aspect and affective aspect. Interactions of cognitive aspect were divided into low and high level, also interactions of affective aspect were divided into positive and negative interaction. The results of this study showed that the verbal interactions in the sociable leader group were more activated than those in the taciturn leader group. Also, interaction level of the sociable leader group in cognitive aspect was higher than those of the taciturn leader group. In affective aspect, interaction pattern of the sociable leader group was similar to those of the taciturn leader group. The characteristics of leader's interaction are as follow. The rates of cognitive aspect in the sociable and the taciturn leaders' interactions were much higher than those of affective aspect. This tendency was especially remarkable in the taciturn leader's interactions. However, interaction level of the sociable leader in cognitive aspect was higher than those of the taciturn leader. In affective aspect, positive interaction rate of the sociable leader and the taciturn leader were higher than negative interaction rate.

  • Background : The purpose of this study is to provide the basic data according to cognitive function, that will help activities of daily living of the elderly through the comparative study of activities daily living and functional training. Methods : The subjects of this study 122 patients 65 years old or more ADL and cognitive function assessment was evaluated. They were registered in the Elderly in nursing homes and welfare centers, located in Gyeonggi. All study participants had a sufficient explanation for the purposes of research and evaluation methods and procedures for the elderly. The survey period 17 October to 11 November 2011 was conducted through face-to-face survey was conducted. Results : Cognitive function according to the K-MMSE score of 24 points or more, 23 to 18 points, 17 points or less were classified. Ability to perform activities of daily living (personal hygiene, bathing, toilet use, stair climbing, dressing, stool control, urinary control, gait, chair/bed, etc.) according to the degree of cognitive function by evaluating the ability to perform daily living compared results in all variables were statistically significant (p<.5). Conclusion : As a result, the higher cognitive functions can be seen that the higher the ability to perform activities of daily living.

  • Purpose: This study reviewed articles related to breast cancer, cognitive function and chemotherapy available in 4 databases. Methods: The researcher reviewed 32 pieces of literature that were published between January 2001 and November 2011. Results: Within the last decade, several studies have investigated whether adjuvant treatment of breast cancer affects cognitive function. A number of prospective studies have reported inconsistent results regarding whether chemotherapy affects cognitive function. Approximately half of the studies reported subtle cognitive decline in a wide range of domains among some breast cancer patients following chemotherapy, and others did not. Conclusion: Breast cancer patients receiving adjuvant chemotherapy showed the most deterioration and the most persistent decline in cognitive function. Since cognitive impairment is subtle, if evident at all, discrepant findings are due to hormonal, physiological, psychological or temporal confounding variables and differences in study design. Especially, that chemotherapy may impair memory, executive function, attention and visuospatial function in women with breast cancer.

  • The tourism industry is influenced by a large number of factors that affect the development scenarios of the tourism in different ways. At the same time, tourism is an important component of the national economy of any state, forms its image, investment attractiveness, is a source of income and a stimulus for business development. The aim of the article is to conduct an empirical study to identify the importance of cognitive determinants in the development of tourism. The study used general and special methods: systems analysis, synthesis, grouping, systematization, cognitive modeling, cognitive map, pulse method, predictive extrapolation. Target factors, indicators, and control factors influencing the development of tourism in Ukraine are determined and a cognitive model is built, which graphically reflects the nature of the influence of these factors. Four main scenarios of the Ukrainian tourism industry are established on the basis of creating a matrix of adjacency of an oriented graph and forecast modeling based on a scenario approach. The practical significance of the obtained results lies in the possibility of their use to forecast the prospects of tourism development in Ukraine, the definition of state policy to support the industry that will promote international and domestic tourism.

  • In this study the effects of science teaming with the level of inquiry requirement in elementary school science experiment instruction were investigated on cognitive domain. We assigned seventy-three students of the fifth grade into two groups according to the levels of inquiry requirement. After each instruction was implemented, the characteristics of the students' tearning science on cognitive domain were compared and analyzed with the levels of them. The higher level (HL) inquiry-required instruction was more effective in increasing and maintaining the memory on the science teaming than the lower level (LL). Especially, in the aspects of the experimental methods and taking cares which the students engage and perform actively rather than do passively, the memory scores of HL group were higher than those of LL. In addition, the memory scores and the degree of maintenance were higher among students who perceived the instruction as easy and interesting. In conclusion, the HL of instruction could stimulate the students to challenge the problems, thereby make them construct meaning actively and improve the amount and degree of maintenance of memory on science teaming.
