The purpose of this study was to explore socio-economic factors as determinants of food behavior and self-evaluation on meeting dietary guidelines. The data were derived from the KNHANES collected in 2007. A multidimensional framework of the determinants of food behavior was used, including age, gender, region, occupation, education, income and nutritional knowledge. The determinants of food behavior and self-evaluation were estimated by ordered logistic regression models. Food behavior was measured by dietary diversity scores including six food groups, which were cereals, vegetables, meats, fruits, milk, and oils. Self-evaluation on meeting dietary guidelines was based on responses from questionnaires for implementing Korean dietary guidelines. In general, the respondents who fulfilled all criteria were few. There were some differences between dietary diversity scores and self-evaluation on meeting dietary guidelines. Age, gender, and educational level showed effect on food behavior and self-evaluation. For dietary diversity scores, the individuals who were younger male, graduated from college were more likely to consume more various foods. The individuals who were older female, graduated from high school were more likely to meet dietary guidelines. Occupation was associated only with self-evaluation. Age and gender were associated with food behavior as well as self-evaluation. Income and marital status were associated only with dietary diversity scores. Reading food label and occupation were associated only with self-evaluation. The food behavior of married individuals was less in line with the dietary diversity scores than singles. In conclusion the differences between objective measure and subjective measure on individuals' diet showed more efforts like segmented nutritional education would be needed to increase the quality of dietary life.

The purpose of this study is to analyze the differences between the cognitive load of mathematics textbooks based on storytelling and traditional mathematics textbooks that are presented to students. In order to verify this, we have selected two 4th grade classes in elementary school that were identified as a homogeneous group through prior testing, and thus were separated into experimental group and comparative group. Then, without the teacher's lessons, the experimental group learned from mathematics textbooks based on storytelling and the comparative group learned from traditional mathematics textbooks. Afterwards, the two groups' cognitive load was measured through a questionnaire, and the following results were obtained: In the 'mental effort' and 'self evaluation' categories, the students that learned from the mathematics textbook based on storytelling showed higher scores than the students that learned from the traditional mathematics textbook. also there was statistically significant difference in some items. However, no statistically significant difference was found in the remaining categories 'task difficulty', 'self evaluation', and 'material design'.

본고는 대만고등교육 평가체제를 대상으로 심아 이를 심층적으로 이해하는데 목적을 두었다. 대만은 2005년 고등교육평가중심기금회(Higher Education Evaluation & Accreditation Council of Taiwan)라는 전담독립기구를 신설하여 평가를 수행하고 있다. 평가의 종류는 대학경영 전체를 평가하는 대학종합평가(校務評鑑), 학문분야평가(系所評鑑), 그리고 특정항목의 산출결과를 통계화하여 대학간 우열을 비교하는 업적평가(績效評鑑)의 세 가지 방식으로 수행하고 있다. 인증제는 학문분야평가에만 적용하고 있다. 평가방법은 먼저 자체평가보고서를 제출한 후 방문평가를 거쳐 평가보고서를 작성하고 결과를 공포하는 일반적인 순서로 접근하고 있다. 평가결과는 통과, 대기관찰, 미통과의 3개로 구분되는데 2008년 6월의 발표에 의하면 미통과 비율이 총 15.7%에 달하였다. 미통과된 대학은 입학정원에 있어 불이익을 받으며 다음해에 추수평가를 받도록 하고 있다. 한편 평가결과에 대한 도태제 적용, 업적평가의 순위 발표에 대한 논란이 제기되고 있으며, 평가위원의 자질 향상, 평가지표의 불합리 등에 대한 문제도 제기되고 있다. 대만의 이러한 특성과 문제는 우리 고등교육평가에도 유의한 시사점을 제공하고 있다.

Information security management systems (ISMSs) are used to manage information about their customers and themselves by governments or business organizations following advances in e-commerce, open networks, mobile networks, and Internet banking. This paper explains the existing ISMSs and presents a comparative analysis. The discussion deals with different types of ISMSs. We addressed issues within the existing ISMSs via analysis. Based on these analyses, then we proposes the development of an information security management evaluation system (ISMES). The method can be applied by a self-evaluation of the organization and an evaluation of the organization by the evaluation committee. The contribution of this study enables an organization to refer to and improve its information security levels. The case study can also provide a business organization with an easy method to build ISMS and the reduce cost of information security evaluation.

The purpose of the study is to report differences in the effects of learner characteristics on the self-regulated learning (SRL) abilities between Chinese and Korean distance learners by using a structured SRL scale. A standardized 54-item self-regulated learning scale (SRAS) was used. The reliability was tested both in China and Korea which showed the scale had good reliability. The comparative study were conducted by administering the SRAS on 1999 Chinese distance learners from the Open Distance Education Center of Beijing Normal University and 1941 Korean distance learners from H Cyber University. Data on four dimensions of SRL - planning, control, regulating, and evaluation - were analyzed using 't-test' and 'ANOVA' with regards to the learner characteristics such as gender, age, prior education level, semesters, location and major. Results indicated that the average participant had an above medium level of SRL ability in all of the four dimensions. There were significant differences in the self-regulated learning ability between Chinese and Korean distance learners. Chinese distance learners scored higher in SRAS than Korean distance learners. The effects of learner characteristics on the SRL ability showed different patterns in the two countries. As for gender, male learners scored better in SRL than female learners in China, whereas it was just the opposite in Korea. No age differences were found in China, but Korean data exhibited a consistent age effect in all dimensions. In Korea, the age group older than 46 scored the highest, followed by the group between 35 to 45 years old, the group between 26 to 35 years old and the group younger than 25. As for location, Korean distance students from metropolitan were better than those from other regions, whereas it was on the contrary in China, albeit the location effect was not statistically significant. Prior education level had a clear and consistent effect on the SRL ability in both countries: the distance learners from junior colleges had better planning, regulating and evaluating abilities than those who came from senior high schools. These results have been discussed in various contexts of distance/online education as well as in relation to different culture between China and Korea. The results will also have implications for designing distance and online learning generally.

This study analyzed the appropriate placement method by floor for evacuating all occupants during the nighttime through evacuation simulation. The analysis results are as follows. First, when non-self evacuating patients were placed on the first floor, 266 patients and 6 workers were found to be evacuated after 460 seconds. This result shows that it is meaningful to place non-self evacuating patients on the lower floor with a time that is faster than 540 seconds, which is an evaluation criterion set using life Safety standards for human. This result is a time faster than the evaluation criteria of 540 seconds, which is set using the life safety standards, and it can be confirmed that it is meaningful to place non-self evacuating patients on the lower floor. Next, as a result of placing non-self evacuating patients from the first floor to the fourth floor, it was found that evacuation of all occupants required 460 seconds for the first floor, 834 seconds for the second floor, 1,508 seconds for the third floor, and 1,915 seconds for the fourth floor. These results indicate that the placement of non-self evacuating patients on the rest of the floors, except for the first floor, can lead to dangerous results in excess of 540 seconds, which is a flashover time. As a result, it is necessary to place non-self evacuating patients on a lower floor for safe evacuation. The study has limitations except for comparative analysis of changes in evacuation time due to changes in the number of workers at eldery care hospitals and situations in which fire-fighting facilities such as sprinkler facilities operated. It is necessary to study the evacuation time linked to the operation of the fire-fighting facilities and the evacuation time according to the change in the number of workers in the future.
