This study is a descriptive study which was done to examine the circumstances surrounding burn accidents in children in order to develop a burn prevention program. The subjects for the study were the mothers of 107 children admitted to two burn specialty hospitals in seoul and the mothers of 172 healthy children attending day care or kindergarten. The tool used in the study was developed by the researchers, pretested and refined. Cronbach's alpha was 0.72. Data collection was done between November 1995 and April 1996. Statistically analysis was done using SAS Version 6.04 and the data was analyzed using test, chi square, regression and logistic analysis. A suumary of the results shows the following : Eighty percent of the children in both groups lived in nuclear families but comparatively more of the children with burn accidents lived in apartments. More of the parents in the group of healthy children had university education and held white collar or professional jobs, while the parents of the children with burn accidents were slightly younger than the parents of the healthy children. but not significantly younger. A significantly greater number of families of children with burn accidents had more than one child and the characteristics of the children with burn accidents that they were more frequently boys, either first or last born and very active. Most of the burn accidents occurred in fall or winter. sometime between noon and midnight and the majority occurred in the home and were caused by hot liquid. In 86% of the cases emergency care was not given at home but the child was brought to the hospital emergency unit. Most of the burns were second degree or greater. involved the arms or legs. required admission, and 41.5% occurred when the parents were preparing or eating meals. In a test of knowledge of preventive measures, the mothers of children who had suffered burn accidents scored slightly higher than the mothers who had no experience with burn accidents, but this was not statistically significant. As to what to do in the case of a fire, the mothers of the healthy children had more knowledge about who to notify. but 70% of the mothers in both groups did not know how to escape from the house if it was of fire. 80 to 96% did not know what do to in case of a fire, such as rolling if clothes were on fire. 80% did not know what emergency care to give for a burn, and 74 to 87% did not know when it is appropriate to try to put out a fire. It can be concluded from this study that. since the results show that the most frequent situation which resulted in burn accidents was when the parents were not aware of the danger of burns or were not paying attention to the child. and when there were no protective devices to prevent burns. and that accidents most frequently occurred at home. the most effective way of preventing accidents is to develop in the parents a "safety mind", Since burn accidents in children are usually more severe than in adults. the physical. emotional. psychological and social damage is greater. In order to develop and awareness of this in the general public. the use of mass media. books and pamphlets and other educational media that provide education on prevention of burn accidents need to be utilized.

The purpose of this study was to examine the degree of occupational therapists' burn-out, professional self-concept, and self-efficacy and also their socio-demographic characteristics and to verify the effects of professional self-concept and self-efficacy on their burn-out. The subjects of this survey were 138 occupational therapists who perform occupational therapy. From October 13th till November 2nd, 2011, a structuralized questionnaire was used to collect data. The results of this study were follows: First, the occupational therapists' mean score of burn-out was 2.12(range: 0-6), and the mean score of professional self-concept and self-efficacy were 2.64(range: 1-4) and 3.56(range: 1-5). Second, according to the general characteristics of the occupational therapists, burn-out showed significant difference by treatment hours per day, duty to work on Saturdays, aptitude and religion. Third, professional self-concept had positive correlation with self-efficacy. And professional self-concept and self-efficacy showed negative correlation with burn-out. Fourth, chief variables affecting occupational therapists' burn-out were professional self-concept and religion. Therefore it is necessary to reduce occupational therapists' burn-out and improve the services of their occupational therapy qualitatively by developing programs to enhance their professional self-concept.

The primary innovation in the new footwear is a heel lift of $20^{\circ}$ which is proposed to improve posture and balance as well as increase shock absorption. The purpose of this research was to compare the movement, forces and muscle activity between the new shoes and standard athletic footwear during standing and walking. Nine healthy subjects participated in this study. Data were collected at two times: 1) when the subjects first wore the new walking shoes and 2) after the subjects wore the shoes for 6 hours a day for two weeks. 1. During standing. the movement of the center of pressure is increased approximately 60% when wearing the new walking shoes compared to a control shoe. 2. During walking. the ankle is approximately $14^{\circ}$ more dorsiflexed during landing due to the 200heel lift in the new walking shoes. The knee compensates slightly by flexing approximately $2^{\circ}$ more. 3. As a result of the changes in the walking movement, the ground reaction forces are applied more quickly, although the peak magnitudes do rut change. 4. The resultant joint moments at the ankle and knee joints decrease from 21-60% with the largest reductions occurring during landing. In conclusion, the new footwear change the movement, showing a more upright stance. Also, the new footwear reduce joint loading at the joint during the landing and weight acceptance phase of walking. However, the influence of the new footwear is immediate and does rut change after wearing the shoes for two weeks.

Police agency is indicated that the number of children's traffic accident is tending downwards, however about one child is dead every day due to traffic accident. Major parts of the accidents happen during walking; among the rest, jaywalking is the biggest reason. Many accidents take plate on the road to school or near the home so government legislate children safeguard zone at 1995. According to the legislation, drivers have to reduce speed and there are safety facilities for children at children safeguard zone. This study finds the problems of children safeguard zone and suggest more effective and quantitative method for children safeguard zone. Firstly this study grasps the characters of children's pattern movement and children's traffic accident at children safeguard zone and then divides specific danger factors of children's traffic accident at children safeguard zone. Secondly, each factor is given danger level depending on danger degree and suggests effective method for assignment standard of children safeguard zone using all of these things.

In this study, the pore-filled ion-exchange membranes were prepared by using the asymmetric PVDF membrane as a nascent membrane. First, the solution of PVBCI having the chlorornethylate aryl ring of 80 percents and DABCO was made with the mixed solvent of THF and DU (8:2). These mixed solution was then, filled in the pores of PVDF membrane, and left for a day to complete the gelation. Finally the pore-filled anion-exchange membrane is obtained fallowed by the amination of the remaining chloromethyl groups with trimethylamine (TMA, 40 wt% in water) forming the positive ammonium ion sites. This 2 step procedure enabled us to produce the pore-filled membranes without change of size, and to control the properties of final membrane with various degree of cross-linking. The results of SEM and AFM showed the polyelectrolyte existed in the pores of nascent membrane as a certain configuration. From the investigation of the solvent affecting much to the permeability and rejection, it was found that the membranes using mixed solvent of THE and DMF (8:2) showed better performances than the membranes produced by THF only. The result of an investigation for the water permeability of the final membrane at low pressure (100 Kpa) showed a typical ultrafiltration membrane's permeability (8 ∼ 10 kg/$m^2$hr) and good values of rejection (55∼60 percent).

The purpose of this study was to examine the effect of myofascical release (MR) on the degree of pain and nerve conduction velocity (NCV) in middle-aged women. Participants were 28 middle-aged women and MR carried out three times (1, 3, 5 day) at intervals of two times. We did survey about changes of pain before the MR and how they changed after the MR. Also measured pressure pain threshold (PPT) and visual analogue scale (VAS) by using the algometer at trapezius muscle. In median nerve, we did motor nerve conduction velocity (MNCV) test and sensory nerve conduction velocity (SNCV) test for measuring incubation period, amplitude and nerve conduction. The most painful time was 18~21 and the most painful part was shoulder. The pain scale, PPT and VAS after the MR had significantly decreased than before the MR. The latency was significantly decreased and the amplitude was significantly increased in the MNCV and the latency was significantly decreased in the SNCV after the MR. Also it was effective in ameliorating pain scale and latency of NCV. Consequently, the MR can be effective in prevent pain scale caused by fatigue in middle-aged women as replacement therapy.

The data on the striped rice, borer populations, collected in the four years from 1973 to 1976, was reanalyzed to study the characteristics in the aggregation pattern of the insect larvae in the paddy fields. The distribution pattern of the larvae was well fitted to the negative binomial model in both the first and the second generation. With reference to the Green's coefficient of dispersion estimated, the aggregation of the larvae was categorized into three phases: initial high aggregation, changing, and dispersed stable phase. Except the changing phase, each phase in each generation could be defined by a common k. The phase-change was initiated by the larval dispersal between hills of the rice plants: the larvae of the third stage and those of the fifth stage, for the first and second generation, respectively. The characteristics of the aggregation pattern were stable in the second generation. In the first genaration, the pattern was more or less variable, indicating that the life system of the insect in the first generation was more susceptible to the variations of the external physical factors than that in the second generation.

In order to obtain basic data on the level of social interest in halitosis and treatment for it, which is a factor of shrinking social life and realistically giving unpleasant feeling to others, we investigated the level of understanding of and interest in helitosis and dietary habits on 552 general adults, and obtained the following results: Findings of our investigation showed that for the time of the intensest halitosis during one day, immediately after getting up in the morning accounted for the highest rate(67.6%). Types of halitosis feeling were a bad smell(67.6%), specific food smell(24.5%) in order. Also, they brush their tooth to prevent halitosis: 42.7% for men, 63.2% for women, 8.9% for male non-smoker, 5.5% for female non-smoker. And findings of investing the degree of desiring halitosis treatment showed that in the case of having bad breath, the proportion of desiring treatment was 9.1% for 'very do' and 28.3% for 'sometimes do'.

The purpose of this study was to investigate the perception and eating behaviors of middle school students in Kwangju area about food and nutrition section of Home Economics course. The subjects were 480 middle school students. The major results were as follows： On the perception f food and nutrition section, the 1st graders learned ‘how to settle the problems related to food and nutrition and food choices’. The 2nd graders learned ‘the knowledge and principle of food and nutrition for improving dietary life’. The 3rd graders learned ‘actual dietary life functions like arranging menu and preparing meals’. Consequently, there was a significant difference in each grade and all boy and girl students have the highest response to the item ‘they learn how to settle the nutrition problem and foods choices’. On the interests in food and nutrition section, lower graders and girl students have higher interest than hgiher graders and boy students. The area which was considered as most interesting in food and nutrition sections was ‘cooking’ in all students. The perception of the concern on dietary life after learning food and nutrition section was higher in the 1st graders. On the perception of the area where was a great change in their own dietary life after learning food and nutrition section, the 1st graders responded there was a great change in ‘balanced dietary life’, the 2nd graders in ‘eating habit and nutrition of adolescence’and the 3rd graders in ‘cooking’. Especially, girl students showed more changes. On the perception of degree which food and nutrition section gives a help to actual life, students over 50% responded that it was helpful to their actual life. This showed that the lower the grades, the more help it gave to those students. On the perception of mother’s job, the students with working mother considered that they learned ‘actual dietary life functions like functions like arranging menu and preparing meals’from the food and nutrition section. In addition, they had high interests in the area of ‘cooking’. It was recognized that as the family size was greater, the food and nutrition section gave more helps to actual life. On eating behaviors of breakfast, the higher the grade, the more frequent they don’t have breakfast, boy students have more frequencies of having breakfast than girl students and the primary reason of not having breakfast is poor appetite. On whether going without a meal affects study or not, most of the 1st, 2nd and 3rd graders whether they are boys and girls or not responded it affected their study. On eating behaviors of lunch, most of boy and girl students in the 1st, 2nd 3rd grade have lunch box. On eating behaviors of supper, eating time is usually between 7：00 and 8：00 p.m and eating hour is mostly 10 or 15 minutes. On eating behaviors between meals, frequency of eating between meals is mostly once or twice a day and girl students have more frequencies of eating between meals, and the cause was hunger commonly in boy and girl students and ‘killing time’in girl students. The focus in getting the foods is ‘taste’and favorite food is fruit regardless of the grade.
