The present study was carried out to analyse the frequency(%) for five kinds of inquiry context elements for six kinds of the high school science textbooks in the 7th curriculum. All the elements was classified into three process achievement level such as the basic, supplementary and further level introduced firstly in the 7th curriculum. Five elements of the inquiry context categories appeared as pure scientific context(61.8%), everyday context(22.2%), natural environmental context(7.7%), techno-industrial context(5.9%), and social context(2.4%) in the basic, supplementary and further level. Social context wasn't appeared in the supplementary level. In five elements of inquiry context, total elements appeared 7,139(85.5%) kfrequencies in the basic level and 691(8.1%) frequencies in the further level. However total elements appeared 529(6.4%) frequencies in the supplementary level. The kinds and frequencies of the elements for the inquiry context suggested in the basic level were more than those in the supplementary and in the further level. The social context was not appeared in the supplementary level. However five inquiry context elements were all appeared in the basic and further level.

The purpose of this study was to examine the effects of the level-differentiated laboratory activities suggested by the 7th national curricula compared to the in-depth level activities only and supplementary level activities only. Two hundred 7th grade students attending a coed middle school were selected for this study and divided into three groups; level-differentiated, in-depth, and supplementary group. In each group, the students were subdivided into the in-depth level and the supplementary level by the formative test after completing the basic learning course. The in-depth and the supplementary laboratory activities were developed and engaged to the respective students in the level-differentiated group for one semester, while only the in-depth activities were engaged to the in-depth group and only the supplementary activities were engaged to the supplementary group. To examine the effects of treatments, the science knowledge test and the inquiry process skill test were administered before and after treatments and the students' opinions about the level-differentiated instruction were surveyed. The results showed that there were significant differences in the science knowledge achievements between the groups while no significant difference was found in the inquiry process skills. Post hoc analysis showed these differences were found between the level-differentiated group and the supplementary group. After the activities, most students in the level-differentiated group responded positively on doing level-differentiated activities except a few students in the supplementary level, These results justify the effectiveness of the level-differentiated laboratory activities compared to the supplementary only laboratory activities in middle school science classes.

Objectives : The purpose of this study was to examine the satisfaction level of dental hygienists with supplementary education. The subjects in this study were 305 dental hygienists, on whom a survey was conducted from September 26 to December 10, 2009. Methods : The instrument used in this study was questionnaires that consisted of three sections: educational environments, the content and method of education, and educational administration. Results : The findings of the study were as follows: 1. In terms of satisfaction level with supplementary education, they gave a mean of 3.13, which was on the average. The dental hygienists who worked in public dental clinics, who had a 10 years or more of career and who worked in the provinces expressed more satisfaction. 2. In terms of satisfaction level with educational environments, they gave a mean of 3.22. They were most gratified with lecturers(3.34), and they expressed the least satisfaction with educational opportunities(3.14). 3. In terms of satisfaction level with the content and method of education, they gave a mean of 3.15. They were most contented with the professionalism of education, and they expressed the least satisfaction with the ratio of theory and practice(2.92). 4. In terms of satisfaction level with educational administration, they gave a mean of 3.02. They were most satisfied with the application procedure(3.22), and they expressed the least satisfaction with educational cost and publicity(2.91). Conclusions : Educational institutions that provide supplementary education should reinforce small-group supplementary education for each district, provide systematic practice-centered educational programs and offer streamlined administration service to boost the satisfaction level of dental hygienists.

As the research about supplementary education of radiological technologist who works in medical clinics, this study was conducted to draw the improvements by analyzing the satisfaction level and problems of the supplementary education. During November 01, 2016 to April 30, 2017, after we distributed a total of 150 questionnaires for the survey to radiological technologists working at medical clinics located in Changwon-si, Gyoungsangnam province, 106 questionnaires suitable for research were analysis by using SPSS 18.0 statistical analysis software. As the sociodemographic characteristics, the age, gender, working period, level of education, and working department were used. And As the welfare factors, working environment, financial support, educational opportunity, medical support, working culture, etc. were used. As the satisfaction factors, 21 items such as system, subject, help, appropriateness of lecturer selection, professionalism were used. And as the problem factors, 18 items such as place, transportation, diversity, administrative treatment, education promotion, proceed method were used. Consequentially, the satisfaction level(3.02 point) of the supplementary education were confirmed as normal level. And the problems(3.18 point) of the supplementary education was analyzed a little higher. The supplementary education is the mandatory education that any health and medical service personnel must complete every three years for license re-issuance. There were many opinions that the supplementary education for radiologists working in various medical institutions did not meet the education level of radiologists working in the medical clinics. In order to improve the satisfaction of the supplementary education of medical clinic's radiological technologist, it should be improved the quality of education through a practical education program that reflects various opinions and improvements on conservative education.

The main objectives of the present study were to understand the knowledge and practice of breastfeeding mothers about the feeding and supplementary food and to analyze the factors related to it. The data for the present study collected from July 9 to July 31, 1984 for 302 mothers in Seoul. 1. The Knowledge of Breastfeeding Mothers about the Fee4ing and Supplementary Food (1) In the knowledge of mothers on the appropriate feeding pattern before 6 month, 69.3% of total women believed that breast-fed babies are healthier. There was a singificant difference in the type of feeding in order to education level, socio-economic state, and. mass-media exposure. (2) In the knowledge of mothers on an appropriate duration of lactation, the mean duration of breastfeeding is 8. 1 month. The duration of breastfeeding gradually decreases in order of education level, socio-economic state, mass-media exposure, and employment status. (3) In the knowledge of mothers on an appropriate time of introduction of supplementary food, the mean time of introduction of supplementary food is 4. 7 month. It is gradually decrease in order of education level, socioeconomic state, mass-media exposure, and employment state. 2. The Practice of Breastfeeding Mothers about the Feeding and Supplementary Food (1) The practice of mothers on infant-feeding before 6 month and that education level, socio-economic state and mass media exposure are the higher, the rate of breast feeding is the less. (2) The mean duration of breastfeeding is 9 month. It is 1 month longer the knowledge of mothers on an appropriate feeding pattern before 6 month. (3) The time of introduction of supplementary food is average 4.75 month. It is similar to the knowledge of mothers on an appropriate time about introduction of supplementary food. The result of this study indicate that the knowledge and practice of breast feeding is maintained comparatively high in low educated group, whereas it is noticeably decreasing among the high educated group. High educated group believed that the short duration of breastfeeding better than long, and they practiced breastfeeding so short period. And high educated group also thought early introduction of supplementary food is good for the babies health. Consequently, in this study, for the most part, elite group is found to have rather wrong opinions and practice about infant nutrition. Therefore the accurate information of infant nutrition is must be encouraged to mothers.

The purpose of this study is to investigate the characteristics of problem solving strategies that gifted students use in science inquiry problem. The subjects of the study are the notes and presentation materials that the 15 team of elementary and junior high school students have solved the problem. They are a team consisting of 27 elementary gifted and 29 middle gifted children who voluntarily selected topics related to dimple among the various inquiry themes. The analysis data are the observations of the subjects' inquiry process, the notes recorded in the inquiry process, and the results of the presentations. In this process, the knowledge related to dimple is classified into the declarative knowledge level and the process knowledge level, and the strategies used by the gifted students are divided into general strategy and supplementary strategy. The results of this study are as follows. First, as a result of categorizing gifted students into knowledge level, six types of AA, AB, BA, BB, BC, and CB were found among the 9 types of knowledge level. Therefore, gifted students did not have a high declarative knowledge level (AC type) or very low level of procedural knowledge level (CA type). Second, the general strategy that gifted students used to solve the dimple problem was using deductive reasoning, inductive reasoning, finding the rule, solving the problem in reverse, building similar problems, and guessing & reviewing strategies. The supplementary strategies used to solve the dimple problem was finding clues, recording important information, using tables and graphs, making tools, using pictures, and thinking experiment strategies. Third, the higher the knowledge level of gifted students, the more common type of strategies they use. In the case of supplementary strategy, it was not related to each type according to knowledge level. Knowledge-based learning related to problem situations can be helpful in understanding, interpreting, and representing problems. In a new problem situation, more problem solving strategies can be used to solve problems in various ways.

The purpose of this experimental research is to investigate the local heat transfer characteristics in the upward free water jet impinged on a downward flat plate of uniform heat flux. The inner shape of rectangular nozzle used was sine curve type and its contraction ratio of inlet to outlet area was five. Experimental parameters considered were Reynolds number, nozzle exit-flat plate distance, and level of supplementary water. Local Nusselt number was influenced by Reynolds number, Prandtl number, supplementary water level, and distance between the nozzle exit and flat plate. Within the impingement region, the Nusselt number has a maximum value on the nozzle center axis and decreases monotonically outward from center. Outside of the impingement region, on the other hand, the Nusselt number has a secondary peak near the position where the distance from nozzle center reaches four times the nozzle width. However if nozzle exit velocity exceeds 6.2 m/s, the secondary peak appears also in the impingement region. The empirical equation for the stagnation heat transfer is a function of Prandtl, Reynolds, and axial distance from the nozzle exit. The optimum level of supplementary water to augment the heat transfer rate at stagnation point was found to be twice the nozzle width.

The purpose of this study was to analyze the current implementation states of the differentiated curriculum at the middle school and to propose ways to improve it. For that purpose this study conducted a survey and had the interviews with the middle school mathematics teachers. The items of survey and interviews consisted of the two main parts: current states and needs about the special supplementary courses and enriched supplementary courses. The results showed that there were discrepancies between the current states and the needs of the differentiated curriculum. This means the efforts to improve the current states are needed. The strategies for improving the implementation of the differentiated curriculum are as follows: 1. The use of various standards including the subject-achievement level and students' or parents' opinions is needed in selecting the students of special supplementary course. 2. More relevant special supplementary materials need to be developed and utilized. 3. The ability grouping is recommended for the differentiated instruction. 4. The deliberation of developing the enriched and supplementary texts is requested. 5. The study for differentiated evaluation of students is demanded.
