Background: The purpose of this study is to determine how the cognitive state of the elderly influences the activities of daily living(ADL) in order to increase their achievement capacity and their ability to exercise this capacity in daily life. The MMSE-K(Mini-Mental State Examination-Korean) was used to evaluate the daily activities and cognitive state of a group of subjects more than 65 years of age. The goal was to understand (1) How their achievement level in their daily activities changes according to the increase and decrease of their cognition points by analyzing and comparing their achievement points in the mental state examination, and (2) What variables influence that daily achievement level. Methods: The survey was conducted by a group of students from AnSan College who were trained for this method of data collection. The group surveyed 224 senior citizens older than 65 to determine their ADL performance. The subjects were selected from Silver Care Centers in the Gyounggi Province area including centers in Suwon, Anyang, Kwachun, and Sanbon City. The subjects were given enough information to fully understand the purpose of the study and the method by which it would be conducted. The survey method was a direct interview: which involved an interviewer reading the questionnaire to the subject and recording the answer. Result: The following results were calculated using SPSS WIN ver. 13.0: In the lower score of the MMSE-K regarding ADL performance (K-MBI) for activities such as individual hygiene, bathing activity, food activity, toilet management, going up stairs, getting dressed ad undressed, controlling stools and urination, walking, and chair/bed movement, most of the subjects responded that they could not perform these activities by themselves (p<.01). In the higher scores for the same activities, most response that they could perform the tasks by themselves (p<.01). In the results of the multiple regression analysis, there influence of the variables for ADL performance (K-MBI) and MMSE-K score was higher for females than males. Conclusion: This study evaluated the cognitive state of the elderly using the MMSE-K, which is the most convenient method, and examined how the cognitive state influences the achievement capacity of the daily lives with other variables. In conclusion, the higher the score on the MMSE-K, the more independent the elders are in the activities of daily living, especially among women more than men.

According to the cognitive conflict process model, student anxiety factor is known to have both positive and negative effects on student response behaviors in a conflict situation for conceptual change learning. However, there is little research that reveals what type of anxiety, either constructive or destructive, is related when conducting step-by-step experiments to resolve cognitive conflicts. This study attempted to learn the characteristic of explanatory hypothesis according to anxiety type after conducting five step-by-step experiments related to action and reaction concept. Results found that students who belonged to the types of 'conviction in logical misconception', 'insisting on additional variables', and 'reasonable modification' suggested explanatory hypothesis close to physical nature. On the other hand, those who showed the other five types of anxiety ('compatible predictions', 'dependence on others', 'fusion of past experience', 'lack of confidence', and 'conflict with past experience') suggested temporary supported hypothesis or simple explanatory hypothesis according to student intuition and simple observation. These results indicate that students in the above-mentioned five categories need more external interactions with instructors based on the type of anxiety related to student behavior. In addition, the results present student characteristics which instructors should be more attentive to when using step-by-step experiments to resolve cognitive conflicts.

The purpose of this study was to identify the effect on improvement of the Activity of Daily Living (ADL) and decrease the cognitive function and agitation behaviors by reminiscence with audio-visual stimulation for senile dementia. The quasi-experimental design was used in this study. Subjects were 26 with mild senile dementia who were cared for at a Day Care Center for Dementia in Seoul. The data were collected from March to July, 1999. Subjects were divided into three groups : Control Igroup with 10 subjects, reminiscence group(Control II group with 8 subjects), and reminiscence with audio-visual stimulation group(experimental group with 8 subjects). The Control I group got routine care as usual. Control II group participated in reminiscence sessions for one hour a day, five times a week , for a period of 4 weeks. The experimental group participated in reminiscence with audio-visual stimulation sessions for one hour a day, five times a week, for a period of 4 weeks. Instruments of this study were color photography with sound that was developed through an open questionnaire about events, objects, humans in action and animals that 100 Korean elderly over 60 would like to memorize. This was referred from the Sensory Stimuli Package by Namazi and Haynes(1994). The effects of treatment was evaluated through MMSE-K by Kwon & Park(1989). Also the Brief Cognitive Rating Scale(BCRS) by Reisberg et al(1983) for the cognitive function, through Agitation Inventory by Cohen- Mansfield and Colleague(1989) for behavioral response and through the Rapid Disability Rating Scale-2(RDRS-2) by Linn & Linn(1982) for the activity of daily living respectively. Data analysis was done using SPSS for $\chi$2- test, ANOVA, repeated measures ANOVA. The results were as follows : 1. Reminiscence with audio-visual stimulation did not improve cognitive function for senile dementia, but significantly improved verbal expression, the subscale of cognitive function. 2. Reminiscence with audio-visual stimulation reduced agitation behavior of experimental group significantly, but there was no significant difference between groups. 3. Reminiscence with audio-visual stimulation did not significantly effect the activity of daily living after treatment. In conclusion, it was shown that the reminiscence with audio-visual stimulation was an effective therapy to improve verbal expression and to reduce agitation behaviors of senile dementia. Further research with more indepth approach is needed, considering characteristic and level individualized for each senile dementia.

Purpose: The purpose of the study was to develop a feasible form of a Korean version of advance directives (K-AD). Methods: Sixteen adults participated in this study: 10 aged 20~50 years and nine aged 65 years or older. Using a draft version of the K-AD, cognitive interview was conducted on the participants to establish a culturally acceptable form of advance directives whose directions can be understood and responded accordingly by the general population. Results: Cognitive interviews revealed areas of concerns for the draft version of K-AD: lack of instructions or clarity for technical and medical terms, context complexity and inadequate response categories. The draft version was revised by rewording, offering examples and rearranging the context. Editorial style was added with appropriate uses of bold fonts, bullet-points and underlines to facilitate interviewees' cognitive responses. Conclusion: Study results feasibility of the revised version of the K-AD. Further study should be performed with a larger number of participants to develop a K-AD with an acceptable level of reliability and validity.

Cognitive impairment and Alzheimer's disease are serious social problems associated with the rising elderly population in Korea. 1,2,3,4,6-Penta-O-galloyl-β-ᴅ-glucopyranose (PGG) is a gallotannin isolated from medicinal plants such as Rhus chinensis. This study was performed to evaluate the effect of PGG on biomarkers related to cognitive function in human neuroblastoma SK-N-SH cells. Inhibition of acetylcholinesterase (AChE) activity is considered to be one of the main therapeutic strategies. PGG inhibited AChE activity in the test tube as well as in SK-N-SH cells. In addition, PGG induced protein and mRNA expression of brain-derived neurotrophic factor (BDNF), which is a mammalian neurotrophin that plays major roles in the development, maintenance, repair, and survival of neuronal populations. As one of the underlying molecular mechanisms that induce BDNF expression, PGG induced the activation of Ca²⁺/calmodulin (CaM)-dependent protein kinase II (CaMKII)-cAMP response element binding protein (CREB) pathway. In conclusion, PGG may be an useful material for improving cognitive function.

The purpose of this study was to develop elementary science programs that used multi-level instruction and to analyze verbal interaction patterns in science classes that applied these programs. For this study, the 27 children from the fifth grade at B elementary school, located in Gyeonggi-do, were selected and separated into heterogeneous groups of four students. Verbal interactions occuring in two groups during each class were recorded using video. Elementary science programs using multi-level instruction were developed to target a fifth grade second semester 'Lesson 1. Human Body'. This program provided a mission form for each group and evaluation form for each child. A mission form depending on the children's level has different colors and levels of difficulty for questions. The evaluation form is composed of questions suitable for a child's level in reaching the goal with key concepts. The verbal interaction was mostly categorized into the cognitive domain and the affective domain for analysis. The cognitive domain was subdivided into question, response, making solution, receiving opinion, and the affective domain was divided into behavioral participation and students' attitude. Results of study showed that the frequency of the cognitive domain was higher than the frequency of the affective domain. In the cognitive domain, the median-level was of highest frequency in the children. In the affective domain, high-level was of highest frequency in the children. In terms of both the cognitive and affective domains of children, low-level exhibited the lowest frequency. Verbal interaction frequency was no difference between high-level and median level in cognitive and affective aspects, so median-level children were actively participating in activities similarly with high-level children. There were more types of interactions question, response, making solution, students' attitude in the median-low level children's verbal interaction than high-median level children's verbal interaction.

Recently the port logistics service has been recognized as a important function of the international logistics, therefore, a lot of papers have been issued concerning the measurement of the service quality of that. But in spite of variety of papers, we can not find out the papers concerning the model of the synthetic customer satisfaction. And also the most of papers concerning the customer satisfaction of service quality have been focused not by cognitive evaluation of the customer, but by affective response. In this thesis, the authors are postulating the model and hypothesis to achieve the research by using the Gr$\"{o}$nroos's model. In order to research the relationship between the port logistics service quality and the customers satisfaction, we are selecting the shipping companies located in Busan and Kwangyang as purchaser and the loading and unloading companies as supplier, and the questionnaires was performed to them. In the result of the empirical study, the technical quality of the port logistics service are affecting directly on the customer satisfaction, but the functional quality are affecting not directly on the customer satisfaction. And also the customer response(affective response) has been proved that it has been exercised as a intermediate role between the port logistics service quality and the customer satisfaction. Therefore it is proved that the affective response of the customer has been exercised a crucial role in the course of supplying the port logistics service.

This study was designed to investigate children's response types, which are always consistent when they meet with different evidence materials. The participants in this study were 119 students of 6th grade in elementary school, who were acquainted with evidence materials presented and able to state logically. Evidence materials were constructed on the main subjects of a cause of the dinosaur extermination and a purpose of the astronomical observatory establishment. The criteria, 'whether or not believe evidence materials presented', 'whether or not believe evidence materials newly presented', 'where or not decrease their belief in the preinstructional evidence materials', and 'whether or not change their belief' were used to classify the type of their responses. So the students' responses to the evidence materials were classified into low types: rejection, reinterpretation, belief decrease, and valuation by evidences. Only about a third of them was also consistent with response types, but the others showed individually different responses to new evidence materials. The types of belief decrease and valuation by evidences were relatively below, while those of the rejection and reinterpretation were likely to represent them again, and these results did not reflect a meaningful difference between male and female. These results show that children's response type are not always coherent, and that they respond variously according to the evidence materials except for an individual cognitive view and a background in estimating evidence materials, and most of them are contents dependent in evaluating evidences. Therefore we are expected to apply it to studies on a thought process of the student as data on the basis of them and develop more various evidence materials responded by basis on evidence.

The purpose of this study is to verify the influence of the cognitive process related to the organizational citizenship behavior. The research method consisted of the cross-design of the prospect dimension and goal orientation dimension, and information security factors consisted of distributive justice, response efficacy, self efficacy, and organizational citizenship behavior. As a result of the study, the dimension of prospect had a significant effect on response efficacy and self efficacy, and it was found that the influence of the gain condition was greater than that of the loss condition. The goal orientation dimension had a significant effect on response efficacy and self efficacy, and it was found that the influence of the growth condition was greater than that of the validation condition. The research model that explained the relationship between information security factors appeared as a partial mediating model between distributive justice, response efficacy, and organizational citizenship behavior. The implications of this study suggest that it is necessary to establish an information security strategy in combination with individual decision-making factors and organizational culture factors.

Marine organisms are frequently used to be harmful and have lower side effects than synthetic drugs. The cognitive improving efficacy of gamma aminobutyric acid-enriched fermented Saccharina japonica (FSJ) on the memory deficient rats, which were induced by trimethyltin chloride (TMT), was investigated by assessing the Morris water maze test and by performing choline acetyltransferase (ChAT), cAMP response element binding protein (CREB), and brain derived neurotrophic factor (BDNF) immunohistochemistry. The neurite outgrowth of Neuro2a cells was assessed in order to examine the underlying mechanisms of the memory enhancing effects of FSJ. Treatment with FSJ tended to shorten the latency to find the platform in the acquisition test of the Morris water maze at the second and fourth day compared to the control group. In the probe trial, the FSJ treated group increased time spent in the target quadrant, compared to that of the control group. Consistent with the behavioral data, these treatments recovered the loss of ChAT, CREB, and BDNF immunepositive neurons in the hippocampus produced by TMT. Treatment with FSJ markedly stimulated neurite outgrowth of the Neuro2a cells as compared to that of the controls. These findings demonstrate that FSJ may be useful for improving the cognitive function via regulation of neurotrophic marker enzyme activity.
