As is the case with South Korea, if the authority for decision making on curricula is concentrated on the state level, the perspective of the understanding on the curricula could be said to be essential. And, such an understanding on the curricula can be important not only to the theorist of curricula but also the teachers in educational institutions. Also, there have been a number of studies to examine the awareness of the teachers on education reform. However, the studies on the resistance factor was mainly focused on the relationships with traits of individuals, covering factors such as their habits, maturity, character, and age, etc. But, it was difficult to find consistency in the results of these studies. Therefore, in this study, the researcher selected the teachers as the key factor of the execution of the curricula and examined the awareness of the teachers on education resistance and the negative views thereupon in the relationship between the knowledge, attitude, skills, and education execution, with a view to find another meaning. The subjects of this study were selected among the teachers in middle or high schools located in Gangnam, Songpa, and Joonggu districts of Seoul. The survey was conducted online with 15 institutions over three weeks from April 13 to 30, 2018. The data gathered were analyzed using SPSS 20.0 and AMOS 20.0, in order to validate the hypotheses through frequency analysis, confidence analysis, factor analysis, structural equation model, and sobel-test. The result of the analyses showed that the factors that affected execution of curricula were the skill system, knowledge system, and attitude of the teachers, in that order, with a positively significant influence. And, significant differences were identified between the factors depending on high or low resistance among teachers.

Physical strength of the rock is the most important factor of resistance to erosion and has been measured through various way. Bedrock microforms, like potholes and grooves, are the forms sculpted by the erosional processes of flow and the location and morphology are strongly affected by the differential erosion. It also assumed that the physical strength of the rock controls the erosion rate and mode of erosion. The schmidt hammer has been used to measure the rock strength in the field for the geomorphological research. To find the relationship between the rock strength and microforms, Schmidt hammer's R(rebound) were measured in the Baeksuktan, middle reach of Gilancheon, Cheongsong, Gyungsangbuk do. The overall values of rebound of the local sandstone showed over 65 in most cases, so it can be regarded as 'very strong'. It is found that the rebound values of the rock surface decreased towards current water level. It also, however, found that there was no systematic differences in rebound values among the topographically high and lows in the bedrock surface. There was no statistically significant difference in rebound values of the area with well developed microforms and others. The values of R from the exposed faces and inside of the microforms are similar. In the case of conglomerate, the part with the gravel showed higher values that the parts with sands. The rebound values are decreased near of(<1cm) the geological discontinuities(including joint and faults), so this line of weakness could be the point of initiation of active erosion to form microforms. However there is large variations in rebound values within this part. It also should be mentioned that topological relation between the strike of the geologic discontinuities and flow direction looks control the mode of erosional processes.

The principal objective of this study was to assess the situation of foodservice facilities, utilities, and physical environment in the Chonbuk area. Self-administered questionnaires were collected from 252 nutrition teachers and school dietitians. Statistical data analysis was completed using the SPSS v. 11.5 program. The results were summarized as follows: Approximately 99.2% of the subjects were women 76.6% were married, over 87% were between the ages of 30 and 40(p<0.01) and 56.8% had more than 11 years of experience(p<0.001). Among the 252 school foodservice systems evaluated, 51.6% of the schools were located in urban areas and 48.0% were in rural areas(p<0.01). Approximately 68.0% of the schools prepared meals in the conventional way, and 32.3% prepared them in the commissary way(p<0.001). The number of employees at each institution was separated into the following categories: 1 to 3(37.7%), 4 to 6(27.8%), and 7 to 9(25.4%, p<0.01). Approximately 54.0% of schools had been running a school meal service for longer than 11 years(p<0.001). However, 67.5% of those facilities had not been remodeled since the initial implementation of foodservices. Approximately 94.0% of the school foodservice facilities were located on the first floor. 72.2% among them were constructed of reinforced concrete and 16.7% were prefabricated(p<0.001). As the result of our evaluation of related physical evidence and the atmosphere of the space, the average importance grade was $4.41{\pm}0.46$, and the average performance grade was $2.78{\pm}0.67$. Most nutrition teachers and school dietitians in elementary, middle, & high schools responded that the related physical evidence and the atmosphere of the space in school foodservice facilities were important, but the satisfaction level among the nutrition teachers and school dietitians was quite low. Therefore, it's important and necessary to analyze the opinions of the stakeholders in the foodservice industry prior to the remodeling of school foodservice facilities and utilities.

This study was carried out to survey the eating behaviors and the food preferences of the tourism transportation business managers in Daegu areas by age. The survey was performed from 17 to August 25, 2003 by questionnaires and the subjects were 365 males. As a general factor, the subjects of survey were male drivers in their thirties to sixties. Their education level was middle school(44.9%) and high school(45.8%) diploma. This study showed that the managers eat three meals per day with high percentage(75.9%) and a large number of managers(24.1%) eat two meals only. 77.8% of the subjects responded that their diet life were irregular due to the property of their job. Frequency of eating-out turned out to be much higher in managers aged 60 over(p<0.001). They considered taste of the food firstly, and the prices of the food secondly, but the nutritional value of the food was considered with a low percentage(22.7%). We found that their BMI were overweight from 23.5 to 26.01, their calorie and some nutrient intakes were below their RDA. The most insufficiently consumed nutrient(less than 75% of RDA) was vitamin B₂ followed by calcium. The food preferences of subjects showed that the managers preferred boiled rice to any other rice as a staple foods. Their favorite menu of one-course Korean style meal turned out to be the bibimbob(boiled rice mixed with assorted vegetable and meat). As for subsidiary foods, out of all various meat soups, beef soups and beef-rib soups were most preferred. The most preferred stew were soybean paste stew and kimchi stew, and the most preferred cooked vegetables were cooked spinach, seasoned cucumber. Baechu kimchi(white cabbage kimchi) were the most preferred kind of kimchi. For desserts there was a very high preference for the watermelons, apples, and pears. For beverages the most preferred were ginseng tea, fruit juices and dietary fiber drinks. From the results listed above, the nutritional education needed to be done to the tourism transportation business managers to set the proper menu considering the characteristics of the preference each age group of managers.

This study observed on habitual methods of toilet training for infants and toddlers in Korea thru 300 mothers at four medical institutions Ewha Woman′s University Hospital, Ewha Maternal and Child Health Center, Severance Hospital and Seoul National University Hospital) with a design to analyze beginning time, duration of period, methods employed, motives, equipments used, special terminology used for the subject training. The main purpose of this study was to generalize the proper methods of toilet training, and also to contribute a better psychological education for the mother and child. The results obtained from this study were as follows; 1. Majority of (67.3%) observed were in the age category between 30 and 40 years, and dominant numbers (64.7%) were housewives with high level of education and from middle class family background. 2. In the most cases (85%), toilet training was carried out by mothers(including wives who had a job) while more than half of mothers (53.7%) maintained their important motive for the training was "due to having high regard for cleanliness" 3. As for the time of beginning toilet training: finding indicated that starting period was decided (70%) at inconsiderate desertion of each mother. whereas, only minority group (30%) represents the cases where mother started the training when they consider tile child was physically and psychologically randy. Also greater number (77.7%) started bladder training prior to that of bowel. 4. It is noticeable that in course of training a large number of mothers (48.3%) applied strict training method when the child proper talenting, and the more rigid and strict in tile training. the more malformation of personality of the infant and toddler were seen after the training period (P<0.01). 5. Over the half of the total cases denoted (bowel 54.3%, bladder 67.7%) starting period before one year and in most cases (bowel 79.3%, bladder 729)the training was accomplished within 12 month, and therefore it was noted that earlier start(before 1 year) shortened the training period (with 12 month) . There was no significant difference between male and female infants in both starting period and duration of period in bladder training, however, in bowel training there was a tendency that female started earlier(7-12 months needed, 51.4%) than tile male (13-18 months needed, largest number 41.4%), and also in cases of female the period for needed for training were shorter than the cases of male. 6. Many a number (bowel 50.3%, bladder 97.7%) employed the method of continuous talenting at regular interval in accordance with that of child′s habit formed before training. Equipment used were various kinds, however, pieces of paper for male (45.5%) and piss pot or bedpost (42.3%) for female were common, on the other hand, "Eung-ga" for defecation (52.3%) and "Shii" for the urination (95.3%) were most standard expression that used during the training period.

This study analyzed the proof of the inverse square law, which is said to be the core of Newton's , in relation to the geometric limit. Newton, conscious of the debate over infinitely small, solved the dynamics problem with the traditional Euclid geometry. Newton reduced mechanics to a problem of geometry by expressing force, time, and the degree of inertia orbital deviation as a geometric line segment. Newton was able to take Euclid's geometry to a new level encompassing dynamics, especially by introducing geometric limits such as parabolic approximation, polygon approximation, and the limit of the ratio of the line segments. Based on this analysis, we proposed to use Newton's geometric limit as a tool to show the usefulness of mathematics, and to use it as a means to break the conventional notion that the area of the curve can only be obtained using the definite integral. In addition, to help the desirable use of geometric limits in school mathematics, we suggested the following efforts are required. It is necessary to emphasize the expansion of equivalence in the micro-world, use some questions that lead to use as heuristics, and help to recognize that the approach of ratio is useful for grasping the equivalence of line segments in the micro-world.

Multicultural families have literally started to settle in Korea since the late 1980s, yet it was not until the middle of 2000 that multicultural education was actually arisen with its full-scale discussions. Domestic studies on multicultural education have now remarkably been conducted in various aspects and points of views, but with no certain level of collective and comprehensive analysis yet. To seek Korean way of finding out appropriate solutions to its multicultural society, a contemporary major trend in the world, it is necessary to keep developing the theory and practice in Korean multicultural education with constructive criticism over the development. In this thesis, the research trends and characteristics of Korea multicultural education are analyzed according to the three categories: the times of the study, the subjects of the study, and the themes of the study. The analysis of the study themes, in particular, is done based on the four core areas presented by Bennett: equity pedagogy, curriculum reform, multicultural competence, and societal equity. Furthermore, the analysis includes the five additional Korean sub-categories, which are also acquired in the process of our analysis of the thesis: multiculturalism, global multicultural education, counselling research, measurement development, and citizenship education, added to Bennett's three sub-ones of each area. Overall, based on the analysis data, this study investigates further improvements and subsequent research themes in the following researches on Korean multicultural education.

Diabetes Mellitus (DM) is well known for increasing morbidity and mortality, especially related to their complications. The purpose of this study was to investigate the factors affecting the prevalence rate of DM and provide a fundamental material to develop an intervention strategy to reduce the prevalence rate of DM. The study subjects were adults aged over 19 on the basis of the primitive data of "The Fifth Korean National Health and Nutrition Examination Survey, 2012". Therefore, the data of 5995 participants were analyzed. For data process, the complex sample analysis module of SPSS 18.0 program was employed to add weighting before analysis. According to the analysis, the prevalence rate of DM of the study subjects was 10.5%. Regarding the odds ratio of DM prevalence, the subjects who graduated from middle school had the odds ratio 2.51 times higher than those who graduated from college and more; those in subjective bad health condition 4.77 times higher than those in subjective good health condition; those in obesity 1.44 times higher; those with high blood pressure 2.57 times higher; those with hyperlipidemia 2.63 times higher; those who fail to control their weight 1.31 times higher; those going on a diet 2.75 times higher. This study revealed that a level of education, perceived health status, obesity, high blood pressure, hyperlipidemia, weight control, and dietary therapy were the predictable variables of the prevalence rate of DM, and thereby suggested the nursing direction and research direction to reduce the prevalence rate of DM.

The purpose of present study was to observe the path and influencing effects between socioeconomic class (SEC), health practices and self-rated health(SRH) by the age bracket. The subjects were 4,987 adults over 25 years old who participated in the 2008 Korean National Examination Health and Nutrition Survey and could be classified into SEC in terms of the three characteristics: education, income and occupation. Path analysis was conducted with the effects of health behaviors execution on the differences in SRH, and the complex samples analysis executed by chi-square test, t-test, ANOVA. As the result, lower SRH level paralleled with the lower SEC, and more health behaviors had differed by SEC in the younger and middle aged group. The lower SEC, the lower SRH: non-smoking and weight control for younger women and exercise for aged men had indirect effects as parameters. In conclusion, when planning a health promotion program, to select the correct target populations with consideration of the age bracket, gender and SEC and to establish tailored contents fit for each of the population would be important.

On 21 September 2010, one of Chuseok holidays in Korea, localized heavy rainfalls occurred over the midwestern region of the Korean peninsula. In this study MTSAT-2 infrared and water vapor channel imagery are examined to find out some features which are obvious in each stage of the life cycle of convective cell for this heavy rain event. Also the kinematic and thermodynamic features probably associated with them are investigated. The first clouds related with the Chuseok heavy rain are detected as low-level multicell cloud (brightness temperature: $-15{\sim}0^{\circ}C$) in the middle of the Yellow sea at 1630~1900 UTC on 20 Sept., which are probably associated with the convergence at 1000 hPa. Convective cells are initiated in the vicinity of Shantung peninsula at 1933 UTC 20, which have developed around the edge of the dark region in water vapor images. At two times of 0033 and 0433 UTC 21 the merging of two convective cells happens near midwestern coast of the peninsula and then they have developed rapidly. From 0430 to 1000 UTC 21, key features of convective cell include repeated formation of secondary cell, slow horizontal cloud motion, persistence of lower brightness temperature ($-75{\sim}-65^{\circ}C$), and relatively small cloud size (${\leq}-50^{\circ}C$) of about $30,000km^2$. Radar analysis showed that this heavy rain is featured by a narrow line-shaped rainband with locally heavy rainrate (${\geq}50$ mm/hr), which is located in the south-western edge of the convective cell. However there are no distinct features in the associated synoptic-scale dynamic forcing. After 1000 UTC 21 the convective cell grows up quickly in cloud size and then is dissipated. These satellite features may be employed for very short range forecast and nowcasting of mesoscale heavy rain system.
