Sleep deprivation is an extremely common event in today's society. It has caused learning cognitive skill deterioration and poor concentration, increased disease such as heart disease, diabetes and obesity, sexual function decrease, infertility increase, depression and autonomic nervous system disorder. Sleep deprivation-induced stress caused NADPH oxidase and oxidative stress. And this oxidative stress induces apoptosis. Lilii bulbus and Nelumbins semen are known to mental and physical relaxation effects. In this study, we induced sleep deprivation(SD) in Sprague-Dawley rats in water for 5 days and thereafter administered orally L. bulbus and N. semen for 5 days. Brain tissues were observed by histochemical, immunohistochemical and tunel staining. The immunoreactives of Tumor necrosis factor ${\alpha}$, Neuronal nitric oxide synthases, Phospho-SAPK/JNK and gp91-phox of the L. bulbus administered group and N. semen administered group were weaker than those of sleep deprivation group. In the L. bulbus administered group and N. semen administered group, apoptosis was decreased than that of sleep deprivation group. Proapoptotic p53, Bax, Cleaved caspase 3 immunoreactives of the administered group were weaker than those of sleep deprivation group, whereas anti-apoptotic Bcl-2 immunoreactity was stronger in the L. bulbus administered group and N. semen administered group. Antioxidant mechanism such as DJ-1, superoxide dismutase 1, Nuclear factor-like 2 immunoreactives of the L. bulbus and N. semen administered group were stronger than those of sleep deprivation group. These results demonstrate that L. bulbus, N. semen had the neuroprotective effects on the sleep deprivation-induced oxidative stress in the hippocampus.

이 연구는 경력개발의 핵심주제로 개인강점이론을 소개하면서 강점의 구성요인, 강점의 개성화, 그리고 취업력을 논한다. 개인강점은 취업력에 관건자원이며 단기적 취업과 장기적 경력개발의 핵심적 능력이다. 취업력은 한 개인의 능력상의 강점과 개성에 대한 체계적으로 조직된 정보로서 개인의 직업적 문제해결을 위한 능력의 결정체이며, 이를 적극적으로 인식할 때, 지식기반사회의 전략적 자원이 된다. 이 연구는 취업력을 한 개인이 검증된 자기의 강점으로 일 기회를 찾거나 창조하여 스스로를 고용시키는 능력으로 정의한다. 경력개발과 취업은 취업력 개념을 통해서 가능할 것인데, 사서를 포함한 대학의 모든 학생들에게 적용될 수 있다. 취업력 제고의 과정이 대부분 개인에 내재적 자료와 외부 상황적 자료를 정보화, 지식화하는 것이므로 문헌정보학, 특히 개인정보경영(PIM)과 개인지식경영(PKM)의 측면의, 기여와 지원이 기대되고 있다.

교육은 목적(목표) 달성을 위해서 의도적이고, 계획적으로 학생을 변화시키는 과정이다. 따라서 초 중등학교의 현장에서는 교육목표를 매우 중요하게 다루고 있다. 이에 블룸은 1956년에 교육목표를 쉽게 설정할 수 있도록 인지적 영역, 정의적 영역, 심리 운동적 영역으로 구분하여 유목화한 교육목표분류학을 창안하였다. 1990년대 이후에는 21세기 교수-학습 이론을 반영하고, 블룸의 교육목표분류학이 갖는 문제점을 보완하고자 앤더슨과 크래스 홀, 마자노 등이 새로운 교육목표분류학을 제시하였다. 블룸, 앤더슨과 크래스홀 및 마자노 등이 제시한 교육목표분류학은 정보와 정보 처리의 과정을 다루고 있다는 점에서 정보활용과정 모형과 밀접하게 관련되어 있다. 이에 본 연구에서는 교육목표분류학과 대표적인 정보활용과정모형인 Big6 Skills을 상호 비교, 분석하여 정보활용과정모형을 재구조화하였다.

Objectives: This study was focused on the influence of chronic aircraft noise exposure on children's continuous performance, intelligence and reading skill. Methods: We enrolled 586 children in 4-6th grade of 7 primary schools near air base in Korea. Continuous performance was measured using the computerized ADS program. We analyzed 477-512 children on the visual continuous performance test, auditory continuous performance test, intelligence test, and reading and the vocabulary test. Intelligence was measured using vocabulary, digit span, block design, and digit symbol tests of K-WISC-III. Results: The commission error and variability deviation of auditory continuous performance test and reading test were significantly higher among children in schools with the helicopter noise and the fighting plane noise compared to children in the low noised schools. Conclusion: There was a possibility that chronic aircraft noise exposure was associated with impairment of the school performance. The result of our study also shows chronic aircraft noise was associated with reading ability.

Purpose: This study was conducted to examine the effects of simulation-based education regarding care in a cardio-pulmonary emergency care as related to knowledge, clinical performance ability, and problem solving process in new nurses. Methods: An equivalent control group pre-post test experimental design was used. Fifty new nurses were recruited, 26 nurses for the experimental group and 24 nurses for the control group. The simulation-based cardio-pulmonary emergency care education included lecture, skill training, team-based practice, and debriefing, and it was implemented with the experimental group for a week in May, 2009. Data were analyzed using frequency, ratio, chi-square, Fisher's exact probability and t-test with the SPSS program. Results: The experimental group who had the simulation-based education showed significantly higher know-ledge (t=5.76, p<.001) and clinical performance ability (t=5.86, p<.001) for cardio-pulmonary emergency care compared with the control group who had traditional education but problem solving process was not included (t=1.11, p=.138). Conclusion: The results indicate that a simulation-based education is an effective teaching method to improve knowledge and clinical performance ability in new nurses learning cardio-pulmonary emergency care. Further study is needed to identify the effect of a simulation-based team discussion on cognitive outcome of clinical nurses such as problem solving skills.

Relapse is one of the most serious problem in alcoholism treatment area. But there is no proper post-treatment management program for preventing relapse in Korea. The purposes of this study are the analysis of several alcoholism treatment programs and recommendation about consideration for developing our alcoholism treatment program to prevent relapse in our country. Five different alcoholism treatment programs were collected for this study, two programs were collected by participant observation and three were collected by instruction manuals, references, and briefing materials. The followings are the criteria for this analysis of the five treatment programs. 1. the specific characteristics of the treatment program 2. the criterion of the patients, the duration and period (or the treatment, the special activities, and goals of the treatment. 3. the common characteristics of the five treatments. The common characteristics of those treatment programs are; 1 preparation for post-treatment from the beginning of the treatment (hospitalization) 2. assessment of relapse related factors 3. assessment of the relapse-warning signs 4. development and plan of individualized intervention strategy 5. practice of the plan The common characteristics of those treatment programs are 1. groups are classified the recovery training groups and the self-help groups 2 all kind of treatment programs carried out as groups rather than individuals. 3. usefulness which apply to various settings and various types 4. multidisciplinary and interdisciplinary approach As results, those programs were developed as post-detoxication management program, follow up program, and continued care program and their theoretical framework was from social learning theory. Those programs used the principles of cognitive-behavioral therapy for the classes, groups, and social skill training. These finding can be used for developing culturally appropriate alcoholism treatment programs focused on relapse prevention.

Purpose: The purpose of this study is to develop a realistic illustration using watercolors on a complete airway obstruction maneuver that is at an appropriate level for elementary school students from the first grade through the third. The illustration is a series of cuts divided into specific frames designed to illustrate the method to be followed in an action or a practical skill that would otherwise be too difficult to explain in written form. Methods: The fundamental theory of the Jeong In-Sung's instruction learning program based on the WEB to construct an appropriate site of instruction learning was used after modification. In this study analysis, design, and production stages were realized. Results: 1. In Stage 1, impressions of the illustration, in sketch form, were received. In Stage 2, results of impressions from a modified illustration were received. After an appropriate level of understanding and accuracy in the practical steps for emergency maneuvers were achieved the illustrations entering Stage 3 and color was added to the sketches. 2. In Stage 3, the illustration was completed by adding color to the contents for the practical steps in the complete airway obstruction maneuver. 3. For composition evaluation, a result of 100% appropriateness was obtained for both items of harmony between illustration and subject being studied and sufficiency in quantity of illustrations. Also high results for appropriateness in items such as clarity, creating interest, illustration size, and tone preference as related to content were achieved and thus completed the production stages. Conclusion: The Complete Airway Obstruction Maneuver Illustration developed specifically for the characteristics and cognitive level of elementary school students grade 1 through grade 3 was appropriate for teaching and learning. There is a need for future research on developed illustrations aimed at elementary school students grade 1 through 3 on the complete airway obstruction maneuver. There is also a need for continued effort in developing certified evaluating tools that can judge the suitability of illustrations and developing illustrations related to emergency maneuvers for various subjects and appropriate for learner level.

Objectives: The purpose of this study is to evaluate the program theory of a lifestyle intervention program for the prevention and treatment of metabolic syndrome. Methods: The program evaluated is a tailored intervention for multiple health behavior associated with metabolic syndrome which is informed by theoretical constructs from the Intervention Mapping and Transtheoretical model. The program components include one-to-one health counseling, a self-management handbook, and a health diary. To evaluate program impact theory we examined the logic of program goals and objectives, intervention methods and strategies, and the theoretical constructs of program materials through document review and matrix building. Results: This evaluation has found that the intervention program applied social cognitive theory constructs to design intervention methods and strategies in addition to the Transtheoretical model: self-monitoring for goal setting and monitoring skill, outcome expectation for the benefits of health behavior change, and interaction with environment for observational learning through modeling. While the intervention addresses multiple determinants and behaviors, it is limited to an individual level and lacks social and environmental approaches. Following the Transtheoretical framework, the contents of the intervention materials were developed utilizing consciousness raising as a main strategy for earlier stages of change, and counterconditioning and stimulus control for later stages of change. Conclusion: Program theory evaluation can be a process of enhancing program validity. It would also be necessary for providing basis for efficient program implementation. When comparisons of program theory between similar programs are possible, program theory and validity will be strengthened when comparisons of program theories between similar programs are possible.

The purpose of this study is to analyze the 6th graders' understanding of the concepts of variable on various aspects of school algebra. For this purpose, the test of concepts of variable targeting a sixth-grade class was conducted and then two students were selected for in-depth interview. The level of mathematics achievement of the two students was not significantly different but there were differences between them in terms of understanding about the concepts of variable. The results obtained in this study are as follows: First, the students had little basic understanding of the variables and they had many cognitive difficulties with respect to the variables. Second, the students were familiar with only the symbol '${\Box}$' not the other letters nor symbols. Third, students comprehended the variable as generalizers imperfectly. Fourth, the students' skill of operations between letters was below expectations and there was the student who omitted the mathematical sign in letter expressions including the mathematical sign such as x+3. Fifth, the students lacked the ability to reason the patterns inductively and symbolize them using variables. Sixth, in connection with the variables in functional relationships, the students were more familiar with the potential and discrete variation than practical and continuous variation. On the basis of the results, this study gives several implications related to the early algebra education, especially the teaching methods of variables.
