Increasingly nursing science is embracing the concepts and methodology derived from psycho-neuroimmunology. It has been previously shown that stress increases and immune function declines in students undergoing examinations. To date, however, no many studies have been reported on stress levels, immune function and interventions in Korean students undergoing their first clinical nursing rotation. It was proposed that nursing students during their first clinical rotation experience increase in stress because of the novelty of the situation and their lack of clinical knowledge. It was also hypothesized that biofeedback and progressive relaxation, methods of self-regulation of involuntary autonomic nervous system responses, would reduce the stress response. The purpose of this study is to test the effectiveness of progressive muscle laxation using biofeedback The effectiveness of the experimental methods was tested by measuring the degree of symptoms of stress (SOS) and the values of ephinephrine, pulse rate, blood pressure and natural killer cells. The subjects of this study were thirty nursing students divided into two groups: experimental group was progressive muscle relaxation group using biofeedback and control group. This study was conducted for 8 weeks of clinical practice. Biofeedback training was done by software developed by J&J company (1-410 form for progressive muscle training). Progressive muscle relaxation training according to Jacobson's Theory was done by messaged word from biofeedback. The data was analyzed using Chronbach' ${\alpha}$ and t-test of the SPSS program and the significance level of statistics was 5%. The results of the study were : 1) The progressive muscle relaxation training using biofeedback was effective for the reduction of symptoms of stress(t=-4.248, p<.001) under clinical practice stress conditions. 2) The progressive muscle relaxation training using biofeedback was not effective for the values of epinephrine(t=-1.294, p=.206). 3) The progressive muscle relaxation training using biofeedback was effective for the reduction of systolic blood pressure (t=-2.757, p=.01). 4) The progressive muscle relaxation training using biofeedback was effective for the reduction of diastolic blood pressure (p=-2.032, 0=.05). 5) The progressive muscle relaxation training using biofeedback was not effective for the reduction of pulse rate(t=-15, p=.988). 6) The progressive muscle relaxation training using biofeedback was effective for the maintenance of natural killer cells (t=2.381, p=02). The first clinical rotation for student nurses is a stressful experience as seen by the rise in the SOS in the control group. Biofeedback using progressive muscle relaxation were effective in preventing the rise of symptoms of stress and the blood pressure means when comparing the pre to post clinical experience, The mean natural killer cell count was depressed in the control group but not significantly different in the experimental groups, It is proposed here that stress via the hypothalamic - pituitary - adrenal axis suppressed the NK cell count whereas the relaxation methods prevented the rise in stress and the resulting immune depression. We recommend relaxation techniques using biofeedback as a health promotion technique to reduce psychological stress. In summary. the progressive muscle relaxation training using biofeedback was effective for the reduction of symptoms of stress under clinical practice stress conditions.

Objectives: This study aimed to develop a school-centered healthy eating environment for children in elementary care classrooms and prevent incorrect eating habits and obesity through the development and application of standardized healthy eating habit-forming educational materials. Methods: Ten schools in eight districts of Gyeonggi-do and 400 students from 19 care classes were selected. Based on the developed educational materials, the program was applied to students once in two weeks. 'Notices for Parents' forms were also sent to the students' home to educate their parents. Pre and post-surveys were conducted to evaluate the effectiveness of the education. The pre-education, education, and aftercare were conducted from September 28 to September 31, 2016, from October 3 to November 30, 2016, and from December 5 to December 9, 2016, respectively. Results: The healthy eating program for elementary care classes was designed to develop a school-centered healthy eating environment and provide standardized educational material for healthy eating habits. Twelve educational topics were developed: , , , , , , , , , , , and . Moreover, the materials were produced in four forms: for students, for after school caring teachers, for external specialists, and for parents. The effectiveness evaluation was conducted to confirm the application of the program. The average eating habits score was 3.3 ± 0.6, with no significant difference between before and after application. The score of overall satisfaction of the education was 3.9 ± 0.9. The most satisfying content was 'Did you get to know how to eat evenly?'. Significant increases were observed in two contents for parents regarding their children's knowledge changes after the education: 'Five nutrients needed for growing children' and 'Knowing sugar foods and sugar-containing foods'. On the other hand, their educational satisfaction was 3.6 ± 0.6, which was lower than the children's satisfaction. This might be because their education was conducted only through the 'Notices for Parents' form. Conclusions: In the long term, the healthy eating habit-formation education for lower elementary school children is expected to be beneficial. To prevent obesity and establish healthy eating habits of children, it is important to develop healthy eating education programs centered on elementary school aftercare classes, including the development of educational materials and an application system through connection with the home and community.

During last five years several workshops and seminars among social work educators, in and out country, has taken place. In those gatherings there has been, criticism on American model on which curriculum of social work in Korea has mainly based, and many proposals which most developing countries should consider and adopt for developing their own curriculums. The proposals could be summarized as follows; 1. Specification of developmental functions of social work should be made so that the curriculum could involve. It also must come from own societal needs and own national development task. 2. Social work should participate and make contribution to plan and solve the main social problems in own countries. 3. Clarification of educational objective in undergraduate level should be made and one of them must be related to the first professional degree. 4. There should be the courses which provide the content of macro level participation. How much of the proposals are reflected in the current curriculum of Korea? What are the problems Korean social work education has been faced in connection with reflecting the proposals? What kinds of task we should or could perform in order to adopt the proposals? These are the questions which deserved to be studied. The followings are the answers to the questions; 1. The new courses such as social welfare policy and planning, Social Development, Population Dynamics and Family Planning, Social problems, Special Issues in Social Welfare, etc, are placed in the curriculum. 2. Though the new courses are added the courses of case work, group work, and community organization are strongly remained it means that integrative method is not quite adopted and that conflicts are taking place between new and old fashion. 3. Fieldwork placement policy has been changes from concurrent to block and from social work method oriented to social problem oriented. 4. There are lack of integration among the all courses, of consistency between pre and post courses and connection among the related courses. 5. Establishment of image of social worker with B, A. degree should be urgently taken place. It can't be done by social work field alone but by cooperation with all the forces related to the social work practice. 6. B. A. graduate should have a common base of knowledge and competence. It could be come from the clear and specified objectives of undergraduate level education. And agreement among the member schools on the objectives can call on the fundamental similarities in each curriculums. Different programs from one school to another can be tolerated as long as there are fundamental similarities among the schools. Basic concepts and framework of social work should be kept clearly. It is a slow and long process to make social work recognized as a profession in the developing countries. Korea can't be and exception. Failure of having social work be indegenous can't be the reason to refuse an change the basic concepts of social work. One of he most important task which social work education in Korea must achieve in the near future is to establish the minimum requirement courses in the curriculum. Social work field, on the other hand, must find the positions for the social works in the various settings and institute. Clear role and image of social worker can be obtained by doing that.

In this case study, we investigated teaching strategies of science teacher's teaching in science museum. Two secondary science teachers who completed a teacher training course on teaching in science museums participated in this study. We conducted interviews about their perceptions on teaching in science museum and their teaching plans before teaching. Then, we observed and recorded their teaching practices in the science museum throughout one semester, and collected all of the teaching materials. The interviews were also conducted after every lessons and at the end of the semester. For the analysis of teaching strategies, we used a framework that was revised from the framework for museum practice (FMP). The analysis of results revealed that the teachers understood the significance of planning the activities in a series of pre-visit, during-visit, and post-visit, so that they structured their teaching as continuous activities, not as an one-time event. However, they showed differences in the extent of connecting the activities with the national science curriculum according to their teaching objectives. In addition, there were differences in strategies such as promoting social interaction, evoking students' curiosity and interest, providing students with choices and control, and inducing engagement and challenge depending on each teacher's perceptions and experiences on teaching in science museum. These results suggest that science teacher education for the professional development of teaching in science museum should systematically provide knowledge and experiences on teaching strategies based on appropriate perceptions on teaching in science museum.

This study was done to compare the breast-feeding primiparas' perceptions of their babies with bottle-feeding primiparas' at 2-3 days after delivery. The subjects of this study included 42 breast-feeding mothers and 56 bottle-feeding mothers. Data were collected by using the Neonatal Perception Inventory(NPI) devised by Broussard (1963) and added by Lee, Ja Hyung(1986) from December, 1996 to June, 1997. The results of this study are as follows, 1. Primiparas' perceptions of their babies according to their general characteristics. 1) There was no significant difference in mothers' perceptions according to mothers' age and whether they have a job or not. 2) There was a difference in mothers' perceptions according to their educational level (P<0.1). 2. The comparisons of breast-feeding mothers' perceptions of their babies with bottle-feeding mothers'. 1) There was no significant difference in the two groups' perceptions of other babies 2) There was no significant difference in the two groups' perceptions of their own babies. (1) Breast-feeding mothes' general perceptions of their own babies were better than bottle-feeding mothers', but there was no significant difference between the two groups. (2) Breast-feeding mothers' perceptions about the basic needs of their own babies were better than bottle-feeding mothers', and there was a significant difference between the two groups (P<0.05). (3) Breast-feeding mothers'perceptions about the sense and motor abilities of their own babies were better than bottle-feeding mothers', but there was no significant difference between the two groups. (4) Breast-feeding mothers' perceptions about the necessary care of their own babies were lower than bottle-feeding mothers', but there was no significant difference between the two groups. 3) There was no significant difference between the two groups' positive-negative perceptions of their babies (1) 69% of breast-feeding mothers and 69.9% of bottle-feeding mothers had positive perceptions about general conditions, but there was no significant difference between the two groups (2) 57.1% of breast-feeding mothers and 46.4% of bottle-feeding mothers had positive perceptions about the needs of babies, but there was no significant difference between the two groups. (3) 50% of breast -feeding mothers and 48.2% of bottle-feeding mothers had positive perceptions about the sense and motor abilities of babies, but there was no significant difference between the two groups. (4) 57.1% of breast-feeding mothers and 60.7% of bottle-feeding mothers had positive perceptions about the necessary care for babies, but there was no significant difference between the two groups. 3. 54.8% of breast-feeding mothers tried to feed their own babies on the 1st day after delivery. 83.3% of breast-feeding mothers chose the feeding method for themselves. Only 9.5% of breast-feeding mothers took recomendations for breast-feeding from nurses. 78.6% of breast-feeding mothers had no chance to learn about breast-feeding. 69% of breast-feeding mothers complained about the difficulties of breast-feeding. The most serious problems were : 'insufficient milk supply', 'lack of knowledge about feeding technique' and 'problems with nipples'.

The purpose of this study was to investigate how preservice secondary teacher teaching practice affected future teachers' features, which they should have as teachers. Based on the differences of pre- and post- test of the survey of their teacher competence, the participants of this study were grouped 40 student teachers as the teaching profession, and 58 liberal arts student teachers of learning teaching of 98 students. This study attempted to seek what preservice teachers expected and sought as future teachers throughout the teaching practice in secondary schools. We considered 5 areas of view of teaching profession knowledge and instruction skill, guidance, personality, and general attitude in the teaching profession as an effective teacher competence. The results showed that pre service teachers asserted that the teaching practice provided opportunities to improve their teacher competence as future teachers. However there was significant effective change in the group of student teachers as the teaching profession. This study also suggested that it is necessary to consider the liberal arts student teachers of learning teaching program reflecting the results of this study.

In school mathematics, the definition and concept of a differentiation has been dealt with as a formula. Because of this reason, the learners' fundamental knowledge of the concept is insufficient, and furthermore the learners are familiar with solving routine, typical problems than doing non-routine, unfamiliar problems. Preceding studies have been more focused on dealing with the issues of learner's fallacy, textbook construction, teaching methodology rather than conducting the more concrete and efficient research through experiment-based lessons. Considering that most studies have been conducted in such a way so far, this study was to create a lesson plan including teaching resources to guide the understanding of differential coefficients and derivatives. Particularly, on the basis of the theory of Historical Genetic Process Principle, this study was to accomplish the its goal while utilizing a technological device such as GeoGebra. The experiment-based lessons were done and analyzed with 68 first graders in S high school located in G city, using Posttest Only Control Group Design. The methods of the examination consisted of 'learning comprehension' and 'learning satisfaction' using 'SPSS 21.0 Ver' to analyze students' post examination. Ultimately, this study was to suggest teaching methods to increase the understanding of the definition of differentials.

In this paper, a new high resolution reflectometry scheme, time-frequency domain reflectometry (TFDR), is proposed to detect and locate fault in wiring. Traditional reflectometry methods have been achieved in either the time domain or frequency domain only. However, time-frequency domain reflectometry utilizes time and frequency information of a transient signal to detect and locate the fault. The time-frequency domain reflectometry approach described in this paper is characterized by time-frequency reference signal design and post-processing of the reference and reflected signals to detect and locate the fault. Design of the reference signal in time-frequency domain reflectometry is based on the determination of the frequency bandwidth of the physical properties of cable under test. The detection and estimation of the fault on the time-frequency domain reflectometry relies on the time-frequency domain reflectometry is compared with commercial time domain reflectomtery (TDR) instrument. In these experiments provided in this paper, TFDR locates the fault with smaller error than TDR. Knowledge of time and frequency localized information for the reference and reflected signal gained via time-frequency analysis, allows one to detect the fault and estimate the location accurately.

One of the goals of the new 2015 revised curriculum is to cultivate the creativity of students who will live in the era of the Fourth Industrial Revolution to create new things through diverse ideas and challenges based on basic learning skills. Accordingly, in order to solve the given problems rationally, the convergence problem solving ability that can process and utilize various areas of knowledge and information is becoming important. Therefore, in this study, we designed the integrative education using a 3D printer based on Tinkercad modeling and applied it to the class to investigate the effect on the improvement of computing thinking ability of elementary school students. To verify the contents of the study, two classes of 25 sixth-grade elementary school students were divided into an experimental group and a controlled group. For the experimental group, 12 classes of convergence education programs using a 3D printer were applied for about three months, and the same amount of general curriculum was conducted for the control group. After that, the t-tests were carried out using the pre-post test to measure the effectiveness of the computational thinking ability. After the application of the program, the experimental group showed statistically significant improvement in computational thinking ability, but the controlled group showed no statistically significant difference. The results show that convergence education using the Tinkercad modeling-based 3D printer has a positive effect on the improvement of computing thinking ability of elementary school students.
