The purpose of this study was to investigate the degree to which the middle school mathematics curriculum matched the item difficulty levels of representative mathematics items. The items used in this study were developed for the National Assessment of Educational Achievement. Ranks for difficulty values of the 60 multiple-choice item were calculated via both Classical Test Theory and Item Response Theory and correlated with the rank order of the mathematics content and cognitive domains sequence. There are six content domains; number and operation, algebra, measurement, figure, pattern and function, and probability and statistics. The cognitive domains include computation, understanding, reasoning and problem-solving. Results suggest a congruence between cognitive domain's sequence and item difficulty levels of items based on that sequence. This finding indicates that the linear or hierarchical assumptions concerning the sequence appears to be reasonable. The characteristics of items that were exceptions to this trend were addressed.

This study investigated the Oriental medicine knowledge and educational requirement of medical staff working in Oriental-Western collaborative medicine hospitals(except for Oriental and Western medicine doctors) based on the recognition that not only mutual understanding and cooperation between Oriental and Western medicine doctors but also the knowledge of Oriental medicine of medical support staff such as nurses, medical technologists, pharmacists and administrative staff are very important to promote Oriental-Western collaborative medical treatment. The study results are summarized as follows : First, it was found that the ratio of nurses who took Oriental medicine education was much higher than those of other groups. They took Oriental medicine education in the types of school curriculum (27.0%) and special lectures in workplace(20.4%). Second, many of the people who took Oriental medicine education were found to be not satisfied with the education in general - 32.7% of them answered the education content was "so so" and 48.4% of them answered "unsatisfactory." Third, the general necessity of Oriental medicine education was found to be an average of 3.60 out of 5, and the number was higher "after employment"(average=3.85) than "before employment"(average=3.04). Fourth, the study found that Oriental-Western collaborative medicine hospital staff are well aware of the necessity of the knowledge of Oriental medicine in the cases of communications between different occupational types, consultations with patients or their guardians, treatment and nursing and the establishment of the practice of specialized Oriental medicine institutes. Fifth, the levels of Oriental medicine knowledge showed a difference in average value according to the role range(p<0.000), and it was found that there is an interaction effect between occupation type and role range(p<0.015).

There are a lot of causes of under-achievement in elementary mathematics, one of which may be lack of previous learning elements. We focus on the understanding of place value. The purpose of this study is to analyze underachievers' levels of understanding of place value concepts and to find the types of place value tasks that they have had special difficulty. For this purpose, an individual test called as "the Six Tasks of Place Value(SToPV)"was applied to ten third grade mathematics underachievers in elementary school. The test is a type of place value concept tests and requires one-on-one interview with some preparation materials. The participants' reactions were analysed according to the framework by Berman(2011). The result of analysis shows that third grade mathematics underachievers tend to have a great difficulty understanding the place value concepts. Also the types of difficult tasks were various from individual to individual. Based on the test results and discussion, we suggested some implications for diagnosing place value concepts of mathematics underachievers.

Background: The healthcare needs of cancer patients are complex and persons involved in their caregiving process are faced with many issues that need to be addressed. The entire family and particularly the person taking on responsibility for patient care develop expectations from healthcare professionals, especially nurses. Objective: The study was conducted to evaluate the impact of a home education program provided to caregivers of cancer patients on the level of their perceived social support and problems in caregiving. Interventions/Methods: The caregivers of thirty seven cancer patients of 2,400 registered people in a family center were given an educational program in this descriptive and cross-sectional study twice a week for a month during the period of March 2011 - April 2011. Results: Of all caregivers, 56.8% were between the ages 36-40, 94.5% were female, 91.9% had received no education on caregiving, 81.0% stated that they mostly felt physically and mentally inadequate in their caregiving. Perceived Social Support from the family indicated a significant difference at $8.05{\pm}4.38$ before and $11.7{\pm}4.97$ after the education. A comparison of the mean scores of caregivers on emotional issues before and after the education revealed the following: spiritual distress scores were $2.54{\pm}0.69$ before and $2.44{\pm}0.43$ after the education; hopelessness scores, $2.24{\pm}0.59$ before and $2.23{\pm}0.38$ after the education; ineffective individual coping was $3.89{\pm}1.42$ before and $2.45{\pm}0.59$ after the education; competing needs in decision-making were $3.54{\pm}0.69$ before and $2.10{\pm}1.24$ after the education; depressive feeling were $3.01{\pm}1.53$ before and $2.02{\pm}0.99$ after the education (p<0.05). Conclusions: Positive effects of home education on levels of perceived social support and caregiving problems of caregivers of cancer patients were observed. Home educational programs for caregivers of cancer patients are important for both better understanding of the requirements of their patients and themselves.

The prevalence of obesity and its related factors in adolescent girls in Seoul area were investigated from April, 18 to June, 29 1985 bymeans of anthropometry, dietary intakes and general environmental factors. Nine hundred and sixty junior high school girls were selected and invterviewed for 24-hour food intakes. Weight, height, a 우 skinfold thickness(triceps, abdominal) were measured and information on the general backgroun of the subjects were obtained by questinnaire. Subjects were divided into six groups according to their relative weights. It was observed that majority of the parents were under fifty years old and had high school education . In general, father was older and higher in educational levels than mother. Two thirds of subjects lived in their own houses and had three to four siblings. AVerage weight and height of subjects were 46.0kg and 154.4cm, which were higher than Korean natianl average. Average relative weight was 29.75 and average Kaup index was 1.925. Skinfold thickness was 13.4mm fo rtricepts and 16.4mm for abdominal . Prevalence of obesity was 12.9% and 4.8% by criteria of relative weight and skinfold thickness. Average intakes of most of nutrients except iron were acceptable but about one third of the subjects had less than 2/3 of RDa for calcium, iron, vitamin A, and riboflavin. As a whole, prevalence of obesity in this study was higher than those observed in the past surveys. Relationship of dietary intakes and general environmental factors that seemed to influence the obesity were integrated as such. As parents educational levels were higher, it tended to be higher in living standard and have fewer family members and siblings. These may influence more nutrient intakes so that fatness of the subjects seemed to be greater. In the meantime, parents fatness was closely related to those of children indicating an involvement of genetic factors. And also, food habits of individuals such as frequency of snack and bedtime snack were related to fatness significantly.

In this study, on the basis of the seventh national mathematics curriculum, the achievement standards were developed to specify the objectives and contents of teaching-learning and the assessment standards were also developed to differentiate students' levels of achievement at school mathematics. The achievement standards were developed on the following guidelines; 1) to present the minimum standards based on the national curriculum, 2) to develop the standards based on the order of curriculum, 3) to suggest the minimum but ultimate achievement target, 4) to comprise not only of the intellectual but also of psychological spheres such as knowledge, function, attitude, aptitude, etc., and 5) to suggest the standards comprehensively and concretely. The standards were developed on the basis of the middle areas of contents of the curriculum in order not to be too comprehensive, nor to be too detailed. Learning activities, on the other hand, were provided for the assistance of instructions with emphasis on creativity rather than on the routine instruction. The assessment standards were established based on the following principles; 1) to establish the assessment methods, contents, and situations which are to be used for assessment, 2) to establish the criteria of classifying the assessed into the upper, intermediate and lower levels, 3) to develop the assessment standards in a proportionate balance to achievement standards, 4) to establish the intermediate level as a standard, and 5) to establish the minimum level in the contents, concepts, values and attitudes of basic learning. This study also suggested the exemplary test items including short-answer and open-ended questions while putting emphasis on students' real performance to increase their ability in solving problems rather than in calculating. In addition to the test items, it introduced the grading system developed to grade the items with concrete guidelines and to report students' achievement on doing mathematics.

An educational system using computers was first conceptualized by Dr. Donald Bitzer in the University of Illinois in the late 1950s. Since the PLATO system was developed in 1961, multilateral research were made for the last 30 years. Especially, the development of Internet and Information Technology has contributed to the advancement of the distance education system. This system has greatly changed the existing educational paradigm, As the result, new education system is being realized, This study suggests a distance education system based on ‘push’ technique, which is a means of active information transmission, In this system, the ‘push’ technique is combined with the existing distance education system. Through the combination, learning contents can be provided for learners without connecting the DB on the Internet. In addition, the process of getting new information is real-timed operation. Also, the treatment of item; and the algorithm of level-based item evaluation are devised in consideration of various levels of learners, so that evaluation of items appropriate to the levels of learners can be accomplished.

This study was performed to assess socioeconomic status and physical health status of middle-aged men ($40's{\sim}60's$) in Ganghwa country. We interviewed 1,267 middle-aged men (602 male, 665 female) by trained interviewers using structured questionnaires including demographic information, general health status, and anthro-pometric measurements. And all the data were analyzed by chi-square test, Student's t-test and one-way ANOVA using SPSS 12.0 version at p<0.05. These results were that males were higher than females in educational levels (p = 0.000) and most of them decreased according to age in educational levels (p =0.000) and family income (p =0.000), and prevalence of chronic diseases (p =0.000): stomach-duodenum disease, fracture, arthritis, or hypertension. They took to the health information on TV and radio and their health managing methods were exercise and walking and resting and diet regulation. Body Mass Index (BMI) was decreased in oder males (p =0.024) but increased in older females (p=0.001). In females, obesity prevalence of 40's, 50's and 60's was 31.3%. 49.7% and 48.0%, respectively. Waist circumference was the highest in 50's males (p=0.015), but hip circumference was the highest in 50's females (p =0.015). Waist-hip ratio (WHR) increased in older males (p = 0.028) and females (p= 0.000). In spite of the subjects were engaged in agriculture and fishery and had desirable lifestyles obesity rate especially abdominal obesity, was the serious problem. Socioeconomic status, especially education and income were related to SRH (p=0.006, p=0.000), chronic disease (p=0.000) and BMI (p=0.028, p=0.000). Therefore, it is necessary that the public health policy and nutrition education programs to alter lifestyles and to improve health preservation and health promotion in the farming and fishing communities.

Objectives: In this study, both subjective and objective levels of oral health were used to identify the relationship between oral health inequalities. Methods: Korean National Health and Nutritional Examination Survey data from 2013 to 2015 were combined to create an analysis plan. Oral health questions categorized as subjective oral health conditions and oral health-related diseases used dental tissue disease status as data measured by the Community Periodical Index(CPI) and decayed, missing, filled teeth(DMFT) experience. Other data on oral health behaviors such as toothache experience, the frequency of toothbrush use, chewing problems, oral examination status, and unmet dental care needs were classified and analyzed according to the socioeconomic level. Data were analyzed using frequency and cross analyses, and the statistical significance level was set at 0.05. Results: It was found that higher the economic and educational level, better was the subjective oral health, lower the CPI, lower the experience of toothache, higher the frequency of toothbrush use, lower the number of people having chewing problems, and higher the frequency of oral checkups. Conclusions: Oral health inequality exists among social classes. It is suggested that continuous research and efforts be carried out to promote oral health while considering socioeconomic and educational levels. Further, active government efforts will be needed to address polarization by social class.
