  • The result of analyzing the cognitive reaction due to the color environment has been applied to various filed especially in medical field. Moreover, the study about the identification of patient's condition and examination the brain activity by collecting the bio-signal based on the color environment is being actively conducted. Even though, there were a variety of experiments by convention the color environment using a light or LED color, it still has a problem that affects the psychological information. Therefore, our proposed system using a HMD (Head Mounting display) to provide a completed color environment condition. This system uses the BMS(Biomedical System) to collect the biometric information which responds to the specific color condition and the human body response information can be measured by the development the Memory and Attention test on Mobile phone. The collection of Biometric information includes electro cardiogram(ECG), respiration, oxygen saturation (Sp02), Bio-impedance, blood pressure will store in the database. In addition, we can verify the result of the human body reaction in the color environment by Memory and Attention application. By utilizing the reaction of the human body information that is collected thought the proposed system, we can analyze the correlation between the physiological information and the color environment. And we also expect that this system can apply to the medical diagnosis and treatment. For future work, we will expand the system for prediction and treatment of Alzheimer disease by analyzing the visualization data through the proposed system. We will also do evaluation on the effectiveness of the system for using in the rehabilitation program.

  • This study was performed to investigate the memory enhancing effect of Poria cocos Wolf (Hoelen cum radix) against scopolamine-induced amnesia in Sprague-Dawley (SD) rats. To induce amnesia, scopolamine (0.75 mg/kg) was intraperitonically injected into SD rats 30 min before starting behavior tests. We have conducted Morris water-maze and Y-maze tests to monitor learning and memory functions. Poria cocos effectively reversed scopolamine-induced memory impairment in SD rats which was represented by an improvement of mean escape latency in water-maze test and spontaneous alterations in Y-maze test. To elucidate possible molecule mechanism, we have measured mRNA as well as protein expression of acetylcholine esterase (AchE), choline acetyltransferase (ChAT), muscarinic acetylcholine receptor (mAchR), and brain-derived neurotrophic factor (BDNF) using RT-PCR and Western blot analysis, respectively. Poria cocos increased mRNA levels of ChAT and mAchR in rat hippocampus compared with those in the scopolamine-injected amnesic group. In addition, protein expression of ChAT and BDNF was also elevated by Poria cocos intake. Furthermore, as an upstrem regulator, the activation of cAMP response element-binding protein (CREB) was assessed by immunohistochemistry. In this immunohistochemical analysis, the phosphorylation of CREB (p-CREB) was reduced by scopolamine injection, which was restored back to control levels by administration of Poria cocos. These results suggest that Poria cocos may improve memory and cognitive deficit in amnesia and have therapeutic potentials through up-regulation of ChAT, mAchR, and BDNF, which seemed to be mediated by activation of CREB.

  • In the process of product design, shaping is the process of making a substantive existence, and ultimately it generates the outcome. The process of shaping is generally led by designer's initiative work, and in this process, various formative elements are used to generate the outcome. In this research, the basic purposes are to figure out the differences of elements which generated by the differences of consumer's and designer's view in the process of shaping of the product, and the characteristics of the affective responses caused by those differences. Also, it will examine how the consumers can directly participate in the process of the shaping of the consumer-participated product, and the feasible guidelines of design in which consumers' needs can be reflected more efficiently to the process of shaping. As a result, consumers and designers have certain degree of difference of view-point about the formative element of the shape. The difference was due to subjective common ideas of design in case of designers, and in case of consumers, it was due to their immature visual understanding. There is another experiment of affective response about the shape of the product. First, I established the sensible image vocabulary based on the shape of the product. And based on the vocabulary, I carried out the same experiments to the consumers and designers.

  • The purpose of this study is to identify various issues contributing to the current issues of students not wanting to major in science and engineering. and further explore various strategies to encourage their higher education in the science and engineering area. The study administered survey on students' perception towards the science related profession including respondents' gender, grade, their attitude towards woman scientists, perception on the woman scientists, scientists as profession, their level of knowledge on the scientists, and if there is any they respect. The results indicated that overall perceptions on the scientists as career for high school students was positive, but there was more negative acceptance for the juniors since they are more concerned with their majors at the university: higher for students who are in the natural science area than the ones in the social science school since they are more directly related than others. The perception on the woman scientists and girls in the science and engineering majors was positive. However, there were some differences in the response level among the items. Among these, considering the job availability and conditions, the perception was more negative than the others. Also the result indicated that both boys and girls disagree that the science-related profession may be gender-inappropriate for girls due to physical and cognitive characteristics. Results also indicated the level of awareness among scientists, they had higher awareness for male scientists than that of the female, and also international ones than the national ones. And many girls did not have positive image of a successful woman scientists.

  • With the advent of the AI, the need to use AI in the field of education is widely recognized. The purpose of this study is to shed light on how prospective mathematics teachers perceive the need for AI and the role of teachers in future mathematics education. As a result, with regard to teaching, prospective teachers recognized that the use of AI in school mathematics is a demand of a new era, that various types of lesson can be implemented, and that accurate knowledge and information can be delivered. On the other hand, they recognized that AI has limitations in having cognitive and emotional interactions with students. As for mathematics learning, the prospective teachers recognized that AI can provide individualized learning, be used for supplementary learning outside of school, and stimulate students' interest in learning. However, they also said that learning through AI could undermine students' ability to think on their own. With regard to assessment, the prospective teachers recognized that AI is objective, fair and can reduce teachers' workload, but they also said that AI has limitations in evaluating students' abilities in constructed-response items and in process-focused assessment. The roles of teachers that the prospective teachers think were to conduct a lesson, emotional interaction, unstructured assessment, and counseling, and those of AI were individualized learning, rote learning, structured assessment, and administrative works.

  • The purpose of this study is to examine the effects of attribute agenda-setting and priming through content analysis and a survey about Particulate Matter($PM_{10}$ & $PM_{2.5}$) using both promotional news and general news. The study results were as follows. First, promotional news and general news were found to showcase similar cognitive attributes. Second, the results did not show a significant relationship between highlighted attributes in media coverage and the public's salient attributes, but media attributes had been generally reflected in the public's perception because the public was highly aware of the importance of all media attributes. Third, the recognition of the public's attribute importance affected the direction of public opinion, which resulted in the acceptance of priming effects. Meanwhile, the recognition of the public's attribute importance towards economic damage, international cooperation, individual response, and the recognition of promotional news had affected risk perception. Furthermore, the recognition of promotional news and involvement appeared to have an interaction effect on risk perception.

  • This study suggests methods of assessing scientific creativity and developing items, which can be achieved when both earth science knowledge and general creativity are applied at the same time. According to the results of this study, the cognitive ability gaps between creativity and scientific creativity were clearly defined by the terms' operational definition. Four factors in the Subcategory Of Scientific Creativity-fluency, flexibility, elaboration, and originality-were selected, and the possibility of developing items out of these factors was discovered. The operational definitions of the four factors were given and the criteria for assessment and scoring were set. The validity, reliability, discrimination, and difficulty, which were the conditions required for the assessment instruments, were verified through three field trials of inputting the assessment instruments for scientific creativity. The assessment instruments were composed of 8 items with 2items for each factor. The average item fitness index obtained was 0.99, Cronbach , the item inter-consistency was 0.79,the inter-rater reliability of each item was 0.78, the inter-rater reliability of each factor was 0.75, the item discrimination power was 0.19, and the item difficulty was 0.00. Because the results were within the permitted limit of the conditions required for assessment instruments, the assessment instruments developed for scientific creativity in this study can be said to be very favorable.

  • Recent research indicates that the new mothers want to learn about childrearing, and have burden in care of infants. Also it indicates that the new mothers say the lack of confidence and knowledge about infant care. This study was a prospective longitudinal reseach developing parent role education program and evaluating the effectiveness of this program for mother-infant interaction, childrearing environment and infant development. Longitudinal quasi-experimental design was used. The subjects were the healthy infants weighing over 2,500gm at birth, whose gestational age was more than 37weeks, and their mothers. The sample consisted of 19 mother-infant dyads for intervention group and 18 dyads for control group. Data were collected from March 15th to December 14th in 1999. For the intervention group received programmed education that was consisted of discharge education, telephone counselling, and home visiting for maternal education. The data were analyzed using chi-square test and t-test to test the equivalence of two groups, and the effectiveness of intervention program. This study was focused on the results of six months time point. The results were as follows: 1. There was significant difference in the mean score of mother-infant interaction(NCAST) between two groups. Intervention group showed higher scores in the subscales of sensitivity to cues, cognitive growth fostering, and caregiver total. 2. There was no significant difference in the mean score of child rearing environment (HOME) between two groups of six-month-infants. But when each subscale of HOME was examined, intervention group showed higher scores in the dimensions of opportunities for variety in daily stimulation, maternal involvement with child, and emotional, verbal response. 3. Six-month-infants of the intervention group showed significantly higher GQ in the Griffiths mental development scale. In conclusion, the maternal education program was effective in promoting the mother-infant interaction, organizing the childrearing environment, and fostering the infant development. These results were very meaningful that we found parent role education necessary for normal infants' mothers, and nurses can make a great contribution in promoting health of infants and mothers.

  • This study consisted of methodological research verifying the validity and reliability of the Korean version of the interpersonal emotion management (IEM) strategies scale after translating and modifying the scale developed by Little et al. The study verified the content validity, construct validity, concurrent validity and reliability based on 189 nurses working at four hospitals in the Seoul and Gyeonggi region. In this study, the Korean version of the IEM strategies scale was comprised of four factors, with a total of 15 questions that included three regarding situation modification, three regarding attention deployment, four regarding cognitive change, and five on modifying emotional response. Furthermore, verification of concurrent validity revealed that the Korean version of the IEM strategies scale was a valid tool as the correlation of the emotional intelligence scale appeared as r=0.60 (p<0.001). The reliability verification showed four factors at Cronbach's ${\alpha}=0.84-90$, confirming that the Korean version of the tool in this study was very reliable.It is important to note that this study provided basic data for the development of educational programs that can effectively control the negative emotions of clinical nurses at the organization level.

  • This study was perfromed to develop the assessment guideline and endpoints for clinical trial with anticancer herbal medicine. The botanical products used to humans for long time may be applied to phase 3 clinical trial after submitting the evidences for safety and efficacy of them or completion of basic requirement of phase 1 and phase 2 for safety confirmation and dose determination. Syndrome improvement was chiefly evaluated by Zubrod and karnofsky(%) methods. We suggest the general clinical trial assessment with botanical products, by following assessment points, that is, tumor size for 50 points, survival fate for 10 points, major syndromes for 40 points. It is recommendable that the each symptom of Qi deficiency syndrome, blood deficiency syndrome and Qi stagnation syndrome was allocated by assessment points, Similarly, the each symptom was given the assessment points according to the severity of symptom, for example, slight for 3 points, moderate for 2 points and severe for 1 point in hepatocelluar carcinoma and lung cancer. Then, the efficacy of botanical products was evaluated by the difference between pre-treatment and post-treatment. Asking the neoplastic patients of questionnaire on physical, emotional, cognitive, social and role subjects availability, three more syndromes (Fatigue, Pain and Nausea/Vomit), quality of life(QOL) will be evaluated by GLM statistics. In addition, in case of lung cancer, 13 questions will be asked by the EORTC QLQ-C13 forms. As the assessment of endpoints for efficacy to reduce side effects induced by chemotherapy and radiotherapy, the data of image scanning and hemato-urinalysis can be usefully applied on immune response, weight loss, indigestion, hemopoietic damage and injury of liver and kidney, while the changes of syndromes of side effect can be evaluated by differentiation methods of Qi and blood and five viscera. However, it is still necessary to determine the ratio between scientific analytical method and Oriental differentiation method as well as confirm the Oriental assessment endpoints by clinical trial. In addition, we suggest the continuous development of assessment endpoints on other carcinomas except of hepatocelluar carcinoma and lung cancer in future.
