The purpose of this research is to survey elementary pre-service teachers' in understand the legal Units, focusing on seven basic unit such a 'm', 'm2', 'L', 'kg', 'K', 'cd', 's'. This study specifically investigates whether the students understand the legal units. The subjects were 1096 students from the University of Education in Jinju, Gyeongnam. Data was collected through a questionnaire which was designed by this research and checked by authority, and the frequency and percentage of responses to each question were obtained and analysed. The survey was the legal units on interesting, using the experience of confusing and understanding of elementary pre-service teachers. The Korea Government is regulating using traditional measures such as 'pyeong' or 'don' in commercial transactions change to adopt the metric system for as a subsidiary the first of July, 2007. The interesting of the legal units dose not exceed a positive answer to the question 52.1%. Their were answered that the experience of the confused of 60.1% in the life. How to do efforts for the settle down of the legal units that answered broadcasting>in class>a campaign>study and training by an academic year in oder. Findings show regardless of academic year, gender and from the department of liberal arts or the science department all the students knew very well that 'm' '$m^2$', 'L', 'kg' are included in the legal units, compared to the others low percentage of 'K', 'cd' and 's' the legal units. In case of time(s), women has correct answered 2.7 times than man. In case of academic year, except for the third-year students was not to exceed 50%. In case of from the department of liberal arts or the science department contrary to one's expectations increase of 50% or more correct answer while half the students scored in science. The elementary pre-service teachers are seems to thinking separate the legal units with their in university life. Also elementary pre-service teachers are the lack of interest on society. Their should be for settle down of the legal units through learning to class in university, newspapers, strengthen publicity activities of broadcast media's further more by maintenance efforts of the government.
The purpose of this study was to examine the Influence of the experience of Childcare Teacher about oral health education on oral health behaviors. For this, Questionnairs to be self-filled up about experience of oral health education were carried out to 267 childcare teachers who are working in nurseries in Geongnam province. The date was analysed using the SPSS 12.0 program. The obtained result were as follows. Among the respondents who are not under stress of oral health. 8.1% respondents had the oral health education and 7.7% others didn't have it. For toothbrushing methods, it was found that 25.3% used manual toothbrushing with experience in dental education(up and down toothbrushing monement) and 35.4% used semi automatic toothbrushing(rotational movement). 37.1% respondents had experiences in oral health education, 69.7% respondents were instructed in the oral health at public health center, and 61.6% respondents were instructed in the oral health a theory(toothbrushing guidance). Among the respondents who answered that oral health education should be necessary, 83.4% of those have already had oral health education where as 73.8% respondents have not had the education. 67.7% of the respondents who want to participate in the oral health education is corresponding to those with experience in dental education, 66.1% respondents with no education feel the necessity of the oral health education.
The objective of the paper is to analyze the extent to which elementary school students acquired, perceived, and practiced oral health knowledge provided by an elementary school-based oral health clinic (SBOHC). It is respectively investigated by gender and year of school. The paper will be relevant for developing specified oral health programs in elementary SBOHCs. By choosing three elementary schools that operate SBOHC in the school district of Daejeon Metropolitan City from April 11 to April 30, 2013, a self-administered questionnaire was given out to be answered directly by 350 students in the 4th, 5th, and 6th grades and their responses were collected. Of the collected responses, 326 responses were explored by using the SPSS 12.0. Those students' scores of oral health knowledge are found to be statistically meaningful for school year, not for gender. In them are included correct tooth brushing time, dental caries symptoms, gum disease symptoms, and correct tooth brushing method. Change in tooth brushing method after oral health education showed the statistically meaningful difference for gender and school year. In conclusion, every SBOHC should develop a variety of specified educational programs that depend on gender and grade in each elementary school.

This study investigated the quality characteristics of factory-style ssamjang (FSS) and commercial handmade-style ssamjang (HSS) products. Moisture, crude protein, and crude fat contents were significantly higher in the HSS groups (49.37~62.12%, 9.39~13.46%, and 4.40~8.35%) than the FSS groups (41.94~45.83%, 7.50~9.09%, and 1.81~3.36%). Salt content was higher in the HSS groups (6.33~11.18%) than the FSS groups (6.10~7.57%). Moreover, the average salt content (7.51%) of the HSS groups and the FSS groups was lower than that of commercial ssamjang (8.73%). Hunter's color value was also significantly higher in the FSS groups. However, free sugar, organic acid, and free amino acids contents varied greatly between the FSS groups and the HSS groups, which was likely due to the different manufacturing method, ripening degree of doenjang and the main material used for ssamjang.

In-stream large wood (LW) has a critical impact on the geomorphic characteristics relevant to ecosystem management and disaster prevention, yet relatively little is known about variations in its dynamics and subsequent export on the watershed-scale perspective in Korea. Here we review variations in the dynamics and subsequent export of LW as a function of stream size, which is appropriate for Korean mountain streams. In upstream channels with narrow bankfull widths and low stream discharges, a massive amount of LW, resulting from forest dynamics and hillslope processes, may persist for several decades on valley floor. These pieces, however, are eventually transported during infrequent debris flows from small tributaries, as well as peak hydrology in main-stem channels. During the transport, these pieces suffer fragmentation caused by frictions with boulders, and stream bank and bed. Although infrequent, these events can be dominant processes in the export of significant amounts of LW from upstream channel networks. In downstream channels with wide bankfull widths and high stream discharges, LW is dominantly recruited by forest dynamics and bank erosion only at locations where the channel is adjacent to mature riparian forests. With the LW pieces that are supplied from the upstream, these pieces are continuously transported downstream during rainfall events. This leads to further fragmentation of the LW pieces, which increases their transportability. With decreasing stream-bed slope, these floated LW pieces, however, can be stored and form logjams at various depositional sites, which were developed by interaction between channel forms and floodplains. These pieces may decay for decades and be subsequently transported as particulate or dissolved organic materials, resulting in the limitation of LW fluvial export from the systems. However, in Korea, such depositional sites were developed in the extremely limited streams with a large dimension and no flood history for decades, and thus it does not be expected that the reduction of LW export amount, which can be caused by the long-term storage. Our review presents a generalized view of LW processing and is relevant to ecosystem management and disaster prevention for Korean mountain streams.
This study has an objective not only to be helpful to the understanding about students' career and employment preparation by investigating the present conditions which are related with vocational consciousness and job values of dental hygiene department graduating students. Study subjects were 350 female graduating students in 3-year-course College, dental hygiene department at five areas of Seoul, Gyeonggi, Gangwon and Gyeongnam. Data were analyzed using IBM SPSS Statistics ver. 19.0. Regarding job values, job prospect of dental hygienist is a little developmental (55.2%) and institution hoping to work is dental clinic (43.2%), reasons for employment in major area are good wage and working environment (24.0%). And regarding opinion about job, dental hygienist job is a measure for living income (69.7%). Regarding job selection conditions, 35.0% subjects replied good human relationship. In the questionnaires regarding professional job in vocational consciousness category, results showed high percentages in that 'the occupation is a job in charge of oral health improvement'; regarding academic area, 'scaling should be done better than dentist'; regarding human relationship, 'harmony between colleagues is closely related with job efficiency'; regarding work ethics, 'development of dental hospital (clinic) and dental hygienist is correlated.' In vocational consciousness of study subjects, higher major satisfaction showed significant differences in professional job consciousness and work ethics consciousness (p<0.05) and the correlation results in vocational consciousness areas showed all statistically significant correlations (p<0.01). In case that the characteristic in one type is higher among 4 types, all other types showed high characteristics and also showed high general vocational consciousness.

This paper, in which whose subjects were 43 cerebrovascular accident patients analysed the effects of flood habits and attitudes on the nutrient intake. In respect to energy intake, the subjects took 106% of RDA. The protein intake was on the average of 119.1 g, which was 187% of RDA. The fat intake by the subjects on the whole was 60.5 g. The fiber intake of the subjects was 9.6 g. Those who like sweets took in significantly less energy and carbohydrate and more fat than those who didn't like sweets. Those who liked salty flood took in 7890 mg of sodium while those who didn't like salty food took in 5579 mg of sodium. The former took in significantly more sodium than the latter (p < 0.05). The examination of the amount of nutrient intake in terms of meal pattern, showed that those who had two meals a day were significantly higher in the level of weight and BMI was significantly higher (p<0.05) and the level of energy, protein, calcium, iron, vitamin A, vitamin C and cholesterol was significantly higher. Those who thought they had heavy meals took significantly more energy, protein, calcium iron, vitamin A vitamin B$_1$and vitamin C than those who thought they had light meals. Rapid eaters took more nutrients than slow eaters. The multiple regression analysis has shown that the effect of the independent variables on the energy intake are in the order of eating speed, eating volume and eating frequency. They can explain 24.6% of the energy intake. As a result, the faster is eating speed, the heavier is eating volume, and the lower is eating frequency, the higher is the energy intake (p <0.01).
Chungkook-jang Koji was fermented with rice straw at $40^{\circ}C\;and\;50^{\circ}C$ for 72 hours. The changes of proximate composition, pH, titrable acidity, nitrogen compounds, protease activity and free-amino acids during the fermentation were investigated. Moisture, lipid and protein contents remained essentially unchanged during the fermentation. The pH was gradually increased from 6.4 to 7.46 and 7.82 at $40^{\circ}C\;and\;50^{\circ}C$, respectively, after 72 hour fermentation. Amino type and water soluble nitrogen increased as fermentation progressed. however, the former slightly decreased after 60 hour fermentation. Chungkook-jang fermented at $40^{\circ}C$ showed somewhat higher protease activity than $50^{\circ}C$. However, protease activity at both fermentation temperatures showed the same trend; that is, it increased until 48 hour fermentation and thereafter decrease. Free amino acid content of Chung-kook-jang after 72 hour fermentation at $40^{\circ}C$ was 6 times greater than that of the steamed soybean, while it was 2.5 times greater at $50^{\circ}C$. Based on these results. it seems that the optimum fermentation conditions for Chungkook-jang were $40^{\circ}C$ and 72 hours.

In order to get the fundamental information that could be useful to judge the potentiality of occurrence of rapid shallow landslide in the objective slope, factors selected on Jinhae regions in Korea, where many landslides were caused by heavy rainfall of daily 465 mm and hourly 52mm in August 1979, was carried out through the multiple statistics of quantification method (II) by the electronic computer. The net system with $2{\times}2cm$ unit mesh was overlayed with the contour map of scale 1:5000. 74 meshes of landslides and 119 meshes of non-landslide were sampled out to survey the state of vegetative cover and geomorphological conditions, those were divided into 6 items arid 27 categories. As a result, main factors that would lead to landslide were shown in order of vegetation, slope type, slope position, slope, aspect and numbers of stream. Particularly, coniferous forest of 10 years old, concave slope and foot of mountain were main factors making slope instability. On the contrary, coniferous forest of 20-30 years old, deciduous forest, convex slope and summit contributed to the stable against Landslide. The boundary value between two groups of existence and none of landslides was -0.123, and its prediction was 72%. It was well predicted to divide into two groups of them.
The purpose of this study was to investigate the relationship of job satisfaction and self-esteem of dental hygienists and nurse's aides. Data were obtained from 327 dental hygienists and nurse's aides who were working at dental clinics, hospitals located in Seoul city. The results, derived from using the SPSS 10.0, were as follows: (1) The level of job satisfaction was 3.02 point, the level of self-esteem was 3.41 point. (2) Service organization and types of occupation have influenced meaningfully on job satisfaction. Hospitals(3.14) are higher than dental clinics(3.0), dental hygienists(3.14) are higher than nurse's aides(2.92). (3) Service organization and types of occupation have influenced meaningfully on self-esteem. Hospitals(3.55) are higher than dental clinics(3.39), dental hygienists(3.52) are higher than nurse's aides(3.31). (4) The correlation between job satisfaction and self-esteem of dentistry employee showed statistically significant correlation.
