  • 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.

  • This study evaluated the effect of the nutrition education about infant feeding on the change of mother's knowledge, attitude and practice of weaning. The subjects consisted of treatment group (n=54) and control group (n=34). The treatment group participated in 6 times nutrition education and 5 times surveys. Nutrition education for weaning of the treatment group improved nutrition knowledge, attitude and practice in infant feeding. Before education, mean scores of control group and treatment group were 7.3 and 7.5 respectively but there was no significant difference. Both group got low score in a statement about weaning period, but they got good score in a statement about weaning method. After education, treatment group got better score(9.1) than control group(8.3) significantly (p<0.05). Treatment group was more desirable than control group specially in a use of Sun-sik, sugar, salt and weaning food mixed with formula after education (p<0.05). Practice of spoon feeding was more frequent in treatment group after education, however, control group used sugar and commercial weaning food more frequently than treatment group(p<0.05). Intake frequency of cow's milk and cookies of infants at age 9-12 month in control group was higher than treatment groups(p<0.01). Thus the nutrition education to mother seems to be effective in achieving desirable dietary behavior of infants.

  • The aims of this study were to investigate the perception of confectionery bakers working in Gyeongnam province for food allergy and to find ways to improve and manage food allergy in confectionery and bakery. The questionnaire was composed of general questions and other questions related to food allergy in confectionery and bakery, and the questionnaires were distributed to the bakers working in Gyeongnam. Sixty nine of 102 confectioneries and bakeries responded to this study, and 60 (87.0%) out of 69 people were aware or had heard about food allergy. However, 54 (78.3%) out of 69 lacked prior education about the management of food allergy. Fifty one (73.9) of 69 people responded that they strongly considered food allergy in the manufacture of the products, but they were not educated about the management of food allergens and symptoms of food allergy. Confectionery bakers were aware about food allergies, but did not label food allergen on the products and have a specific management for food allergens at the work site. Therefore, it is necessary to educate the confectionery bakers about food allergy and to develop and distribute a manage program of food allergens in the field. The result from the present study could be used as basic data for the investigation of awareness for food allergy of confectionery bakers working in Korea.

  • This study aimed to evaluate the effectiveness of a foodservice and cooking program for children attending community child centers in Korea. The foodservice and cooking program included a reference menu, nutrition and hygiene class for foodservice managers, as well as cooking classes for children during the winter or summer vacation in 2015. In order to evaluate the program, a survey was conducted before and after the program. A total of 1,120 children who participated in the program completed questionnaires regarding eating behaviors, food intake, and their opinions and levels of satisfaction with the program. The scores of children's eating behaviors increased significantly from 59.71 to 63.62 out of 85 points (p<0.001). A significant increase was detected in children's food intake. Vegetable intake, which received the lowest scores, increased significantly from 3.63 to 3.81 out of 5 points (p<0.001). The score for opinions and satisfaction concerning the program was 28.34 out of 35 points. These results suggest that the foodservice and cooking program could be helpful in promoting healthy food habits in children attending community child centers.

  • This study was conducted to investigate the effect on the habitation of Monochamus alternatus, a vector insect of Pine wood nematode by the tended sound stumps for the developing forestry control methods of Pine wilt disease controls. Field cage plots (1 m ${\times}$ 1 m ${\times}$ 1 m) were established 12 units (Experiment1:4 units, Experiment2:8 Units) and were treated 4 kinds(February in 2010, February, April, June in 2011). The adults of M. alternatus were put into 4~5couples each the cage June in 2011. Presence or absence of the larva entrance holes and larva were detailed November in 2011. The larva were appeared in the sound stumps of sapling and young trees tended at February, April, June, the current emergence year of M. alternatus, but were not appeared in the sound stumps of sapling and young trees tended February in 2010, one year before the emergence of M. alternatus. The larva habitated in stumps of sapling were likely to be smaller in size in compare to the larva in stumps of young trees. In case of young tree, the larva were found at the cleft part of bark, but were not found at ridge part of bark. All observed larva appeared at part of bark and between the bark and the woody parts, but were not found at the woody parts. To develop the control guiding principal of sound stump after forest tending practice, further experiment need is in existence oviposition and larvae of vectors by height of stemps.

  • The user cost is an important analysis item which should be considered together with life-cycle of facility, administrator cost and discount rate in LCCA for efficient asset management of SOC facilities. Especially, a significant delay cost occurs often for users in the road field due to a work zone for cleaning and maintenance, and in such case, the administrator should consider the administrator cost as well as the user cost for more rational decision making. However, the user cost has not been considered in most decision making steps until recently and relevant studies also have not been carried out actively. In this study, the methodology to estimate the user cost and delay cost required in the decision making step using the traffic flow model and the direct benefit estimation model in the traffic facility investment evaluation guideline is suggested. And, the traffic flow model was estimated on 4 national highway sections where maintenance was actually carried out in 2014 using VISSIM and, the user cost and the delay cost were estimated based on the suggested methodology. The analysis result showed that the average user cost of $17,569,000KRW/km{\times}day$ occurred on Section A with approximately 30,000 AADT before a work zone occurred, and in case the first lane was blocked for maintenance, the delay cost of $10,193,000KRW/km{\times}day$ (158%) on average occurred additionally. The delay cost of $1,507,000KRW/km{\times}day$ (115%) and $1,985,000KRW/km{\times}day$ (119%) occurred on Sections B and D with approximately 20,000 AADT respectively and the delay cost of $262,000KRW/km{\times}day$ (105%) occurred on Section C with approximately 10,000 AADT. This result of this study was estimated based on the simulation of traffic flow model so that there is a limitation in its actual application. A study ot develop a highly appropriate model using actual observation data and improve the possibility to apply it through the verification using the simulation will be necessary in future.

  • The purpose of this study was to examine portion sizes and nutritional quality of foods served to children at Community Child Centers (CCCs), July 2014, in Korea. A survey was administered to foodservice employees working at CCCs. Thirty-nine participants completed the self-administered questionnaire regarding CCCs foodservice practices. In the weight test, fifteen volunteers of demonstrated typical portion sizes for $5^{th}$ grade elementary school students. Nutrition knowledge scores were significantly different between foodservice employees with experience taking a foodservice class for one year (6.04 out of 10.0 points) and those without experience (4.58 points). Foodservice employees with experience taking a foodservice class scored significantly higher in performing meal serving practices, e.g., wearing a sanitary cap and apron when serving food, than those without experience. The amount of foods served for children did not meet standard serving sizes; portion sizes of rice, soup, main dish, side dish and kimchi served by foodservice employees were 87.3%, 63.2%, 56.5%, 37.1% and 81.3% of standard serving sizes, respectively. When energy and nutrient intakes from portion sizes were calculated, energy, vitamin A, thiamin, riboflavin and calcium intakes did not meet standards for nutrition control of school meals. However, protein, vitamin C and iron intakes met more than 100.0% of standards. These findings suggest that foodservice employees with experience taking a foodservice class apply their knowledge to foodservice practices. Although portion sizes can influence energy and nutrient intakes in children, the actual portion sizes served by CCCs foodservice employees were inadequate and did not meet standards for serving size and nutrition. Thus, all CCCs foodservice employees need to receive foodservice education and be provided guidelines regarding portion sizes for children.

  • This study described the status of snack intake and personality of middle school students, determined the differences in snack intake and personality according to gender and grade levels, and examined the effect of snack intake on personality. Data were collected from a self-reported survey from students of a middle school in Gwangju city and 717 questionnaires used for the analyses. The data were analyzed for frequency, percentage, mean, standard deviation, Cronbach's α, t-test, ANOVA, Duncan test, and multiple regression analysis using SPSS/PC 18.0 program. The results obtained were as follows. First, as for the snack intake frequency, '1~2 times per a day' had the largest number of responses(42.3%), followed by 'sometimes'(37.6%), '2~3 times per a day'(12.6%), 'never'(7.5%). As for the reason of snack intake, 'habitually'(27.3%) had the largest number of responses, followed by 'insufficient amount of meal'(21.0%), 'skipping meals'(13.6%), and 'stress relief'(8.2%). Mean score of agreeableness was the highest(3.64) among the personality components followed by Openness/intellect(3.42), Extraversion(3.36), Conscientiousness(3.15), and Emotional Stability(3.09) on the 5-point scale. Second, there were statistically significant differences in Emotional Stability depending on the gender. There were statistically significant differences in Extraversion, Agreeableness, and Openness/intellect by the grade level. Third, fruit intake frequency had statistically significant influence on Extraversion(β=.134). Intake frequency of bread(β=-.099), fruit(β=.142), ice cream(β=.092), and rice cake(β=.090) had statistically significant influence on Agreeableness. Intake frequency of bread(β=.105), drink(β=-.113), fruit(β=.113), and flour-based food(β=-.126) had statistically significant influence on Emotional Stability. Intake frequency of fruit(β=.106) and milk(β=.110) had statistically significant influence on Openness/intellect. Intake frequency of fruit had statistically positive influence on all the personality components. Intake frequency of rice cake had statistically positive influence on two personality components. Intake frequency of drinks had statistically negative influence on Emotional Stability. The outcomes indicate that snack intake affects the personality of adolescents.

  • Purpose: We assessed the nutritional status and the alterations of oral diets during anti-cancer chemotherapy in pediatric oncology patients. Methods: Twenty children with malignancy were evaluated from day 0 until day 21 of post-chemotherapy. Nutritional status was assessed by body weight and biochemical parameters. The amount and calories of oral diets were assessed and food preference before and during chemotherapy were analysed by questionnelle. Results: 1) The underlying diseases of 20 patients were 11 acute lymphoblastic lekemia, 2 non-Hodgkin's lymphoma, 2 Langerhans cell histiocytosis, 2 Wilm's tumor, 2 brain tumor, 1 rhabdomyosarcoma. 2) There were weight loss during chemotherapy in 8 patients (40.0%), weigt gain in 5 patients (25.0%), and no significant changes in 7 patients (35.0%). 3) Biochemical parameters showed no significant interval changes during chemotherapy except elevation of serum ALT level. 4) The daily caloric intakes of oral diets during chemotherapy were 310~600 Kcal which was much lower than average of daily recommended calory for Korean children. 5) The most favorate food was altered by chemotherapy, from meats to carbonated beverages and unfavorate food was not altered as vegetables. Conclusion: The periodic assessment of nutritional status and dietary supplements according to preferred foods of patients will be required for the optimal nutrition care in cancer patients.

  • Since the introduction of Israeli carp into Korea for farming in 1973, there are no breeding studies on developing Korea Israeli carp (domestic) so far. This study performed gene-based cross-breeding studies to restore genetic diversity of lowered Israeli carp through continuous inbreeding, and for rapid growth and better scales. This study produced four cross-breeding groups (F1) using Koean Israeli carp and Chinese Songpu mirror carp for the improvement of growth and scale of Israeli carp in Korea. And mating scheme for breeding groups was set in consideration of the morphological analysis and genetic distance of broodstock. In addition, this study used microsatellite markers and genotype data to analyze genetic diversity and parentage analysis. As a result, the average NA and HE values of Korean select broodstock are 8.3 and 0.743, and F1 is 13.0 and 0.764. This study shows that the genetic diversity of F1 has been recovered over Korean Israeli carp through breeding between Korean Israeli carp and Chinese Songpu mirror carp. Common Israeli carp in Korea reached 1.7 kg in 17 months, and improved Israeli carp reached to 2.2 kg. The KC (Korea×China, KC) group was 2.52 and broodstock group was 3.15. F1 showed lower scale score (0.63) than broodstock. The improved carp (F1; CK, KC) had 20% better scales than the parent group (F0), which improved 27% in weight and 25% in scales compared to common Israeli carp. The Israeli carp developed by the genetics-based breeding grew quicker and had improved genetic diversity and fewer scales, which will be of great value for Korean Israeli aquaculture industry due to good marketability.
