The objectives of this study were to classify the types of vegetation in Pinus densiflora for. erecta stands. The study sites were located at Sokwang-Ri, Mt. Chungok(1,276m), Uljin, Mt. Kumma(1,017m) and Mt. Eungbong(1,267m). Two hundred thirty releves were classified and explained by phytosociological analysis(the method of ZM schools), and the results were summarized as follows. Pinus densiflora for. erecta stands were classified into Vaccinium koreanum community, Rhododendron micranthum community, Quercus dentata community, Acer pseudosieboldianum community, and Typical community. Quercus dentata community was divided into Festuca ovina group, Robinia pseudoacacia group, and Typical group, and Acer pseudosieboldianum community was divided into Hydrangea serrata for. acuminata group, Disporum smilacinum group, Magnolia sieboldii group, Carpinus laxiflora group, and Typical group, and Typical community was divided into Melampyrum roseum group and Typical group. And some groups were divided into 7 subgroups. Therefore, Pinus densiflora for. erecta stands had total of 16 vegetation units, out of those units, Vaccinium koreanum community distributed all over the studied areas. While Rhododendron micranthum community distributed mainly at Sokwang-Ri and Mt. Chungok. Therefore it was considered to be useful indicator in determining the range of afforestation and natural distribution of Pius densiflora for. erecta stands. The classified vegetation units were investigated by using of coincidence method. The results indicated that Quercus dentata community distributed mainly below 100 meters at the sea level, while other communities distributed above 350 meters at the sea level. According to the correlations between vegetation units and topography, Vaccinium koreanum and Rhododendron micranthum communities distributed mainly above middle slope areas, Quercus dentata community distributed mainly from lower slope to upper slope areas, Acer pseudosieboldianum community distributed mainly between valley and lower slope areas, and Typical community distributed mainly above upper slope areas. According to the correlations between vegetation units and 5 study areas, Quercus dentata community was distributed in the region of Uljin, and other communities were evenly distributed over other studied areas. According to the correlations between the units and aspects, all communities occurred all aspects, but most of the communities tended to be more distributed at south slopes than at north slopes, which meant that the relic stands of Pinus densiflora for. erecta were remained largely as patch phase status at south slopes.

This study was carried out to purpose drawing up the efficient method of rural residents' health management, analyzing factors having influences on the behavioral intention and the behavior of hepatitis B vaccination of rural residents, using the theory of planned behavior(TPB). Surveying the first questionnaire about TPB to 439 people of rural adults over 40-year old who participated to hepatitis B examination program was made from March 14 to April 23 in 2001 at two primary health care posts in a city in Gyeongsangbuk-do and the second survey for hepatitis B vaccination was made to the last subjects of 332 people(75.6%) that had been proved as subjects of inoculation against the hepatitis B as the result of examination after two months of notification. In the behavioral intention rate of hepatitis B vaccination of the subjects within a month, 100%(the top) was 45.2%, 80-90%(the middle) was 21.1% and under 70%(the low) was 33.7%. In simple analysis, vaccination intention was related with significantly health security type and economic status(p<0.05). And vaccination intention was related with significantly all variables of attitude toward behavior and subjective norm, and economic power of utilizing medical facilities and perceived power variable of perceived behavioral control(p<0.01). The vaccination rate of the subjects within a month was 31.3%. In simple analysis, the vaccination rate was higher significantly in the lower the age was, the higher the educational level was(p<0.01), the larger the family was, and subjects having transport(p<0.05). And the vaccination rate was higher in the higher the economic power was and the higher the perceived ability was. As the results of making generalized logit analysis for behavioral intention, the more positive the subjective norm was, the higher was the score of the perceived behavioral control, the intention was higher significantly in the top class on a basis of the low class of behavioral intention. In multiple logistic regression analysis for vaccination(behavior) using intention and perceived behavioral control as dependent variables, it showed that perceived behavioral control variable only influenced significantly. The higher was the score of perceived behavioral control, it showed that they got the more vaccination(p<0.01). And even in the result having analyzed, adding the significant general characteristics variables in the simple analysis to the independent variable, the higher was the score of perceived behavioral control, it showed that they got vaccination more.

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.
