In this study, we developed education materials using history of science related to the experiment of 'Boyle's air pump' and the Boyle and Hobbs' debate of vacuum to find out the perceptions of NOS by pre-service chemistry teachers. For the study, 29 pre-service chemistry teachers at a college of education in Chungcheongbuk-do were selected. As RFN items that were related to the contextual situation developed in this study, items in the categories of 'Aims and Values', 'Scientific practices', 'Scientific Methods among Educational Applications' and 'Social-Institutional Aspects among Educational Applications' were selected. Through the items of RFN, the perceptions of pre-service teachers in non-contextual situations were investigated. Then we presented the pre-service teachers with the situation related to Boyle's experiment on air pump and Boyle and Hobbes' debate over vacuum. In addition, their perception of NOS was examined in contextual situations related to RFN items. Responses to the items, experimental results related to Boyle's Law, group discussion, and interview data were collected as data. As a result of the study, it was found that pre-service teachers had informed perceptions in most of the items, but cases with naive views or mixed views were found in context experimental situations. This study can contribute to the NOS education for pre-service chemistry teachers by development of context situation education materials related to NOS and by finding out their perceptions in the non-contextual and contextual situation.

Background: For children and adolescents with cancer, going back to school is a key milestone in returning to "normal life." Purpose: To identify the support vital for a successful transition, we evaluated the parents' needs and the challenges they face when their children return to school. Methods: This multi-institutional study was conducted by the Korean Society of Pediatric Hematology and Oncology. The written survey comprised 24 questions and was completed by 210 parents without an interviewer. Results: Most parents (165 of 206) reported that their children experienced difficulties with physical status (n=60), peer relationships (n=30), academic performance (n=27), emotional/behavioral issues (n=11), and relationships with teachers (n=4) on reentering school. Parents wanted to be kept informed about and remain involved in their children's school lives and reported good parent-teacher communication (88 of 209, 42.1%). Parents reported that 83.1% and 44.9% of teachers and peers, respectively, displayed an adequate understanding of their children's condition. Most parents (197 of 208) answered that a special program is necessary to facilitate return to school after cancer therapy that offers emotional support (n=85), facilitates social adaptation (n=61), and provides tutoring to accelerate catch up (n=56), and continued health care by hospital outreach and school personnel (n=50). Conclusion: In addition to scholastic aptitude-oriented programs, emotional and psychosocial support is necessary for a successful return to school. Pediatric oncologists should actively improve oncology practices to better integrate individualized school plans and educate peers and teachers to improve health literacy to aid them in understanding the needs of children with cancer.

Objectives：This study was to investigate the impact of parental psychiatric disorder on offspring's depression, anxiety, self concept, perception of familial relationship compared with offspring of normal control. In offsprings of parents with psychiatric disorder, this study explored whether their psychopathology, self concept, and perception of familial relationship were influenced by parent’s sex, onset time of parent’s psychiatric disorder and parent’s psychiatric diagnosis. Methods：52 offsprings aged 10-18 years of 39 psychiatric outpatient were surveyed from June, 1997 to April, 1998 and completed several questionnaaire, including Korean from of the Family Environment Scale, Korean form of the State-Trait Anxiety Inventory for Children, Korean form of Kovac’s Children’s Depression Inventory, and Korean form of Piers-Harris Children’s Self-Concept Scale. Their score was compared with offsprings’ of normals. In offsprings of parents with psychiatric disorder, they were compared according to parent’s sex, onset time of parent's psychiatric disorder and parent’s psychiatric diagnosis. Results：The results were as follows：1) Offsprings of parents with psychiatric disorder reported higher level of state anxiety and lower level of the FES expressive subscale than offsprings of normals(p<0.05). But they reported higher level of PHCSCS intellectual & school status subscale and popularity subscale than normals(p<0.05). 2) There were no differences in anxiety, depression, self concept, and perception of familial relationship between patient’s sex. 3) Offsprings less than 3 years old when parent’s psychiatric disorder had developed showed higher level of trait anxiety and lower level of FES control subscale than offsprings more than 3 years old (p<0.05). 4) There were no diferences in anxiety, depression, self concept, and perception of familial relationship between patient’ diagnostic groups(schizophrenia spectrum disorder-mood disoderneurosis). Conclusion：The finding indicated that self reported scale of anxiety and depression showed no significant difference between offsprings of psychiatric patients and offsprings of normals. In offsprings of parents with psychiatric disorder, parent’s sex and psychiatiric diagnosis had no influence on offspring’s psychopathology. But the offspring’s age(before 3 years old) when the parent’s psychiatriric disorder developed had influence on higher level of offspring’s trait anxiety. For further high risk group study, direct interview and evaluation of parent-child agreement or teacher-child agreement will be needed in longitudinal study.

Purpose: This study aims to examine perceived safety management in teachers working for young children with disabilities, to grasp the state and problems of safety management and first-aid education at daycare center for young children with disabilities, and to provide basic materials to develop programs for safety management and first-aid education. Results: 1. For the perception items of accident possibility in daycare centers, career with more than 10 years had higher response in 'very high' and 'moderately high' than 'moderately or very low' and statistically significant difference was found(p < .05). 2. For the perception items of accident prevention in daycare centers, no teaches with at least college education thought that 'it was not possible to prevent' and most of them thought that 'it was totally possible to prevent' and statistically significant difference was found(p < .05). 3. For the performance level of safety management and first-aid items, forty and over(4.73) showed higher than age of 20-29(4.32) and 30-39 of age(4.26) and statistically significant difference was found(p < .05). 4. For the knowledge level of safety management and first aid items, the highest religion was found as Christian(16.96), followed by Catholic(15.33), Buddhism(14.91), and no religion(15.81) and statistically significant difference was found(p < .05). 5. For the items of confidence in safety management and first aid, performance level, and knowledge level, teachers who competed safety management and first-aid education( 4,48) had higher performance score than those who did not (4.17) and statistically significant difference was found(p < .05). 6. For the items of confidence in safety management and first aid, performance level, and knowledge level, teachers who competed first-aid education(2.77) had higher confidence than those who did not(2.35) and statistically significant difference was found(p < .05). Conclusion: The results suggest that safety management and first-aid education in teachers working for daycare center for young children with disabilities was closely correlated with knowledge and performance levels. Thus, it is necessary to provide continuous safety management and first-aid education for teachers working for day care center for young children with disabilities through regular in-service training. Also further research should be conducted with all subjects and various regions who contact with young children with disabilities.

The triglyceride compositions of peach kernel and apricot kernel oil have been investigated by a combination of high performance liquid chromatography (HPLC) and gas liquid chromatography(GLC). The triglycerides of peach kernel and apricot kernel oil were first separated by thin layer chromatography(TLC), and fractionated on the basis of their partition number(PN) by HPLC on a C-18 ${\mu}-Bondapak$ column with methanol-chloroform solvent mixture. Each of these fractionated groups was purely collected and analyzed by GLC according to acyl carbon number(CN) of triglyceride. Also the fatty acid compositions of these triglycerides were determined by GLC. From the consecutive analyses of these three chromatography techniques, the possible triglyceride compositions of peach kernel and apricot kernel oil were combinated into fifteen and thirteen kinds of triglycerides, respectively. The major triglycerides of peach ternel oil were those of $(3{\times}C_{18:1}\;30.9%)$, $(2{\times}C_{18:1},\;C_{18:2},\;21.2%)$, $(C_{18:1},\;2{\times}C_{18:2}\;10.6%)$, $(3{\times}C_{18:2}\;3.8%)$, $(C_{18:0},\;2{\times}C_{18:1},\;1.8%)$, $(C_{16:0},\;C_{18:1},\;C_{18:2},\;1.5%)$, $(C_{18:0},\;C_{18:1},\;C_{18:2},\;1.1%)$ and those of apricot kernel oil were $(3{\times}C_{18:1},\;39.5%)$, $(2{\times}C_{18:1},\;C_{18:2},\;24.5%)$, $(C_{18:0},\;2{\times}C_{18:2},\;14.2%)$, $(3{\times}C_{18:2},\;2.0%)$.

Many landslides occurred at the western part of Gyeongnam province by the typhoon No. 875. Their conditions and causes were investigated and were summarized as follows : The total number of landslide occurred was 2,490 and its area was 156.53ha. In about 94% of landslides and about 97% of landslides area occurred in 3 counties, Sancheong, Hamyang and Geochang. The landslides smaller than 0.01ha was 49% of the total indicating that about half of them were the small landslides. Considering homogenous topography amount of precipitation and forest type landslides appeared to be mainly has a high affected by the geological factor because the landslides mainly occurred in the deep weathered soil of igneous rock. The landslides occured on concave slopes of 31 to $35^{\circ}$ in steepness with low crown density. In the area of the deep weathered soil, landslide likely occur repeatedly. Therefore, regular erosion control works are recommended in the area of pos for disaster prevention and counter-measures.

The aim here is to analyse the system of description of GIS in all of the high school textbooks passed with the official approval, to find the degree to which teachers understand about GIS, and to consider the present condition of GIS instruction. Most of the authors of textbooks generally underestimate importance of GIS, and there is difference among their awareness. In the system of description of GIS, there are only a few kinds of textbooks in which explanation of GIS is made coherently from the purpose of instruction aim through the chapter summary and to overall test in both of the Korean Geography and the World Geography. This trend is due to the degree of distribution of the GIS specialists in writing a textbook while the other texts books shows just a brief introduction of GIS concept. Although there is the limit for teachers to study how to teach GIS due to its very technological aspect as well as few previous training and teacher's guide. Thus it is evident that about a half of teachers who responded taught high school students without a knowledge on GIS, and a few of them even never referred to that concept. These facts may negatively affect the status of a geography in the society of information. For the solution of these issues, it is considered how to repair the description system and its contents. Besides, the variation among textbooks is reduced at the further revision of the 7th curriculum. And the printed matters of GIS are sufficiently provided for the teachers to use as their teaching aids. It is desirable that the GIS instruction models should be further developed for college education, and the programs for the on-the-job teachers training should be arranged. Besides, the previous training for the on-the-job teachers should be achieved more practically with enough time before the revision of curriculum.

Objectives This study aims to build the baseline data for promoting school health care program by identifying satisfaction level and improvement point through the satisfaction survey after Korean medicine doctor's student health and wellness program in 2016. Methods An association of Korean medicine doctor in Seongnam city conducted Korean medicine doctor's student health and wellness program for 12 middle schools, 6 high schools and 1 special-need school in Seongnam city in 2016. The participating Korean medicine doctor visited each school for 8 times and conducted health consultations, health education classes and Korean medicine treatment for the school students and the school employees. Teachers and administrators from the participating schools answered the self-reported satisfaction questionnaires and the results were analyzed by SPSS 22.0. Results 35 people responded the program satisfaction questionnaires, the overall satisfaction average was $9.40{\pm}0.88$ (out of 10). In the course of the program, satisfaction average regarding the student's health check-ups was $9.05{\pm}0.88$, satisfaction average regarding the informatory brochures for the parents was $9.08{\pm}1.09$, satisfaction average regarding the participation enrollment process was $9.06{\pm}1.16$, and the satisfaction average regarding the questionnaire statistics and the result reports was $8.86{\pm}1.93$. The satisfaction average of the program was as follows: health consultation ($9.20{\pm}1.08$), treatment ($9.31{\pm}0.90$), and health education classes ($8.78{\pm}1.68$). Some of the good things about program were 'Telling students about their physical condition' (57.1%), 'Curing the sick student quickly' (48.6%), 'Providing students with useful information about the health' (48.6%), 'Teaching students how to manage their health and how to manage symptoms' (42.9%). Average satisfaction about sustainability and needs of the program was $9.15{\pm}0.91$, and the participant teachers wanted to learn more about how to manage internet addiction (22.9%), stress (45.7%), atopy (28.6%), neck pain (42.9%), allergic rhinitis (37.1%), and low back pain (34.3%) from the future wellness programs. Conclusions Student health care is one of the most important issue in national health policies. We have designed a bridge model that a local community, school, and doctors can work together to develop. After the implementation of the program, the results of the satisfaction survey showed a very high satisfaction level. This study can be the basis for further improvement of the bridge program as well as the expansion of the program in other settings.

Clothing is considered as a means of self-projection in the childhood and children show clear preference on their own favorite clothing on which their latent identity is reflected. Changing sex-role identity, in particular, in the modern complex society specially affects the clothing behavior of children. The purpose of this study is to investigate the clothing behavior of children in conjunction with sen-role identity and home environment variables. This study will provide fundamental information on the clothing behavior in the childhood and be of help in selecting appropriate clothing in accordance with the variation of sex-role identity. Necessary information for this study was obtained through a questionaire. 'Bem sex-role identity inventory' was used to investigate the effect of sex-role identity and the clothing behavior was studied in conjunction with the factors of conformity, dependence, aesthetics and interest. The subjects of investigation are composed of three hundred male and female elementary school students in the 5th and 6th grades. For the statistical analysis of the collected data, percentage(%), mean value(M), standard deviation(SD) and Pearson's correlation coefficient were calculated and t-test, $x^2$-test, and Duncan's multiple range test were performed. The results form this study are as follows : 1. Sex-role identity shows a little difference according to gender, order of a birth and standard of living. This small difference is shown to be statistically insignificant. 2. In clothing behavior in connection with the sex-role identity, statistically significant trend was not found in typical sex-role identity group. However, clothing behavior in modernistic sex-role identity group exhibits statistically significant results in the factors of dependence, aesthetics and interest at the level of P<.001. 3. As concerns the clothing behavior in connection with gender, boy students show statistically more significant tendency in aesthetics and interest than girls do. However, boy students show statistically more significant tendency in aesthetics than girls do in connection with the standard of living. Although the clothing behavior associated with the level of parents education, mother's age and existence of mother's job shows a little difference in mean values, statistically significant trend was not detected. 4. Clothing behavior of the children shows a meaningful correlation between the factors. 5. Through 3-dimensional variables analysis, it is found that there is no mutual interaction between gender, sex-role identity and standard of living on the clothing behavior. The results from MCA supplementary analysis reveal that there is difference according to the gender, sex-role identity and standard of living.

Fish fauna and community structure were surveyed in the Nakdong River, Gumi City, Kyeongpook province from April 2001 to July 2002. During the surveyed Period, 39 species, 32 genera belonging to 10 families were collected. Cyprinid fish occupied 64.1% (25 species) and cobitid fish had 7.7% (3 species). Fourteen species(35.9%) of observed species were known as endemic species. The exotic fish was Micropterus salmoides (2.5%) . The dominant species were Zacco platypus (relative abundance: 36.7%) and Opsariichthys uncirorstris amurensis (22.7%). Carassius aurafus and Microphysogobio rapidus were numerous (4.0${\sim}$4.3%). The rare species comprising less than 0.15% were Acheilognathus koreensis, Aphyocypris chinensis, Iksookimia longicorpus, Coreoleuciscus splendidus, Rhinogobius giurinus, Sarcocheilichthys variagatus wakiyae, Silurus asotus astus, and Channa argus. It was found that the population density of carnivorous Opsariichthys uncirostris amurensis increased drastically in the mid-reach of the Nakdong river since it had been introduced from the other native rivers in the middle 1990s. Gobiobotia nakdongensis inhabit riffle (water velocity : 0.43${\sim}$0.67 m $s^{-1}$) of which the river bed is mainly sand. This species is considered to be in need of conservation. As the result of analyzing fish community in the surveyed area, the species diversity, evenness and dominant indices were 1.008, 0.663 and 0.196 respectively. The findings showed that the tributary, which the waterside plants were abundant and had various habitats, had a higher species diversity (1.112) than the main river (0.787). Sand mining had been disturbing the river ecosystem of the study stations 3, 11, 13 & 14, and these stations showed a quite low species diversity (0.421 ${\sim}$0.574).
