The purpose of this research was to evaluate the correlation between obesity, threshold of salty taste, optimal saltiness and blood pressure in middle school students in a fishing village. The subjects were 115 boys and 103 girls in middle school in a fishing village. The BMI index and systolic and diastolic blood pressures of subjects were measured, and the subjects were divided into a normal and obese group according to their BMI. The threshold of salty taste and salt preference for a semisolid dish (steamed egg dish), liquid dish (bean sprout soup), and a solid dish (raw radish salad), were estimated by sensory evaluation. Calorie intake was measured using the weighing plate method. The boys in the obese group showed significantly higher systolic and diastolic blood pressures than those in the normal, but girls did not. Furthermore, calorie intakes of the boys in the obese group were significantly higher than those in the normal group, but this was not shown in girls. On the threshold of salty taste, both boys and girls in the obese group needed higher concentration of salt than those in the normal group. The threshold of salty taste were significantly positively correlated with systolic pressure and diastolic pressure in boys. Regarding the salt preference in the steamed egg dish, bean-sprout soup, and raw radish salad, both boys and girls in the obese group preferred higher concentrations. The higher concentration they preferred, the higher the systolic and diastolic pressures were in boys, but only systolic blood pressure was higher in girls. From these results, it is evident that a nutritional education program is needed in school to help restricting middle school students salt consumption and decreasing obesity to prevent hypertension.

본 연구는 운전자 연령대와 뇌손상 여부에 따라 다양한 반응시간 과제에서의 반응시간과 반응정확성에서 어떠한 차별성이 있는지 살펴볼 목적으로 수행되었다. 이를 위해 30-50대의 중년운전자, 65세 고령운전자, 그리고 65세 이상의 뇌졸중 고령운전자들을 대상으로 단순반응, 2-선택반응, 자극 이심률을 달리한 4-선택반응, 탐색반응 및 동적자극 탐지 과제에 대한 수행을 비교하였다. 본 연구의 결과를 정리하면 다음과 같다. 첫째, 전반적으로 중년, 고령 및 뇌졸중 고령운전자 순으로 느린 반응시간을 보였으나 자극 이심률이 작은 조건(5o)에 비해 큰 조건(10o)에서 뇌졸중 고령운전자의 반응시간이 다른 집단에 비해 더 두드러지게 지연되었다. 둘째, 전체 반응시간에서 단순 반응시간을 감산한 반응시간 을 분석한 결과, 2-선택반응 과제와 동적자극 탐지과제에서의 집단간 반응시간 차이는 유의하지 않았는데, 이것은 이러한 과제들에서의 반응시간 차이가 단순 반응시간에 의해 주로 결정된다는 것을 시사한다. 셋째, 일시적 기억을 요구하는 탐색과제에서는 두 고령운전자 집단이 중년운전자 집단에 비해 유의하게 느리고 부정확한 수행을 보였다. 넷째, 집단간 반응정확성에서의 차이는 선택 대안이 많은 과제와 기억을 요구하는 과제에서 두드러졌다. 이러한 결과는 기억 요구를 수반하는 탐색과제는 중년과 고령운전자 사이의 수행을, 반면 자극이심률 조건은 뇌졸중 여부에 따른 고령운전자 집단에서의 수행 차이를 민감하게 반영할 수 있음을 시사한다.

This experiment was carried out to study the effect of rice black-streaked dwarf virus(RBSDV) infection rate on forage productivity of corn varieties in Cheonan of chungcheongnamdo from 2006 to 2008. Forage corn varieties of 10 were cultivated with first cropping(seeding in the last ten days of April) and second cropping(seeding in the last ten days of May) system in field and tested the infection rates of RBSDV and productivity of forage. The Infection rate of RBSDV was significant difference between corn varieties in middle district of Korea. Resistant corn varieties for RBSDV were ‘Kwanganok’, ‘P3156’, ‘Kwangpeyongok’ and ‘P3394’ but susceptible varieties were ‘Suwon19’, ‘DK697’, ‘GW6959’ and NC+7117. Dry matter(DM) yield of forage corn according with infection rates of RBSDV in field was significant difference between varieties(p<0.05). DM yield of susceptible varieties, ‘Suwon 19’, ‘DK697’ and ‘GW6959’ was lower about 20% than that of resistant varieties, ‘Kwangpeyongok’ and ‘P3156’. For increasing the productivity of forage corn, recommend of resistant varieties for RBSDV and control of seeding time are very important in middle district of Korea.

In this study, we investigated the correlation between the number of cyanobacterial species and the water quality factors after installation of Nakdong river weirs. Factor analyses of water quality factors were also performed. The results of correlations showed that there was no significant water quality with the cyanobacterial concentration but the correlation coefficient of nutrients increased from the upstream to the downstream. There was a significant correlation between W·T and pH as important water quality factors for the growth of cyanobacteria. In the downstream region of Nakdong river, algae were more frequently detected than in the upstream region, and the blooms of algae species seem to be influenced by the higher pH and the influx of the phosphorus from the upstream tributaries. Nutrient concentration was higher in the downstream region than in the upstream region due to the effects of tributaries Geumho river and Nam river in Nakdong river. As a result of the factor analyses, nitrogen species were the principal factors in the upper region, and phorsphorus species were the principal factors in the downstream region.

PURPOSES : The purpose of this study is to investigate the fundamental behaviors such as stresses and deflections of the middle slab in a double-deck tunnel for the development of a middle slab design guide. METHODS : The middle slab has been divided into the following three different sections as according to its structural differences: the normal section, expansion joint section, and emergency passageway section. The normal section of middle slab represents the slab supported by brackets installed continuously along the longitudinal direction of tunnel lining. The expansion joint section refers to a discontinuity of middle slab due to the existence of a transverse expansion joint. The emergency passageway section has an empty rectangular space in the middle slab that acts as an exit in an emergency. The finite element analysis models of these three sections of middle slab have been developed to analyze their respective behaviors. RESULTS: The stresses and deflections of middle slab at the three different sections decrease as the slab thickness increases. The emergency passageway section yields the largest stresses and deflections, with the normal section yielding the smallest. CONCLUSIONS: The stress concentrations at the corners of the passageway rectangular space can be reduced by creating hunch areas at the corners. The stresses and deflections in the emergency passageway section can be significantly decreased by attaching beams under the middle slab in the passageway area.

This study aimed to compare energy nutrient intake, health related factors, physical characteristics, blood biochemical indices, prevalence of metabolic syndrome and odds ratio (OR) of metabolic syndrome based on dietary fat energy ratio. Subjects were 1,205 men aged 40~64 years. The average fat intake was 52.8 g. Subjects were divided into three groups (deficient, normal, excess) based on dietary fat energy ratio. The dietary fat energy rations of the three groups were 36.9%, 42.9% and 20.2%, respectively. Energy and protein intake were increased significantly with dietary fat energy ratio (p<0.001), whereas carbohydrate intake decreased (p<0.001). In health related factors, amount of smoking alone showed increase based on dietary fat energy ratio (p<0.001). In comparing physical characteristics, blood pressure and blood biochemical indices, excepting diastolic blood pressure, increased significantly based on dietary fat energy ratio (p<0.01~p<0.001). The rate that exceeded criteria in risk factors for metabolic syndrome was higher in the serum triglyceride (41.2%) and was lower in the waist circumference (22.2%). Prevalence of metabolic syndrome was 37.9%, and showed significant correlation to dietary fat energy ratio (p<0.05). The OR of metabolic syndrome was higher in deficient and excess group than in normal group, but it had no relationship between fat energy ratio and metabolic syndrome. The results of this study provide basic data to establish fat intake guidelines for prevention of metabolic syndrome in middle-aged men.

The purpose of this study was to investigate perception of the Food Allergy Labeling System (FALS) of school foodservice in female middle school students. The subjects were 148 female middle school students in the Incheon metropolitan area. In this cross-sectional study, data were collected using self-administered questionnaires. Only 20.9% of subjects had experience of food allergy education. There was no significant difference in food allergy knowledge by grade. The scores of perception of food allergy labeling by school foodservice were significantly higher in lower grade students (p<0.001). In all grades, highest scores were observed for ‘food allergy labeling is necessary’, whereas the lowest scores were for ‘I check the food allergy labeling’. The percentages of subjects who wanted to participate in food allergy education were significantly different (p<0.01); 73.8% in 1st grade, 50.0% in 2nd grade, and 35.7% in 3rd grade. For desired education contents to enhance perception of FALS, 57.5% of subjects answered ‘emergency management’ and 23.0% said ‘information of food allergy causing food’. Therefore, it is necessary to increase food allergy education and educate female middle school students according to grade in order to enhance perception of FALS.

Since a free-learning semester has been introduced to middle school curriculum, interest in career experience programs has increased. To respond to this new demand, we developed a continuous agriculture-related career experience program linked with STEAM (Science, Technology, Engineering, Arts, and Mathematics) education, and we examined the program’s effects on the job awareness of middle school students. The program was conducted from April 8, 2015 to June 24, 2015, and consisted of 12 classes. The direct experience subprogram was based on 13 different horticultural activities that reflect producing (nine programs), cooking (two programs), and sales (two programs) of horticultural produces. For the indirect experience subprogram, we preliminarily selected 10 representative agricultural jobs, and based on the keywords analyzed from 7 direct experience programs, we chose to introduce seven jobs to the students by videos and the three others by written material. We then investigated the effect of introductory videos on job interest, understanding, and preference by the students. We found that the student’s interest, understanding, and preference regarding each job were significantly improved when direct experience and video watching were combined. Career awareness was improved for gardener (47.0%), nursery grower (42.0%), rural extension official (31.1%), eco-friendly farm material developer (30.9%), agricultural research official (23.4%), plant doctor (19.8%), and agricultural wholesale distribution experts (9.3%). Conclusively, it is expected that career experience programs have the greatest effect on students when both interest in the job and participation on direct experiences are encouraged.

Animal-Assisted Intervention programs and interventions with students are becoming promising field in school and therapeutic settings. Following this trend, Animal-Assisted Intervention (AAI) program was designed to help students adopt more easily to school life and to encourage them to keep healthy relationships with others. Accordingly, the purpose of this study was to identify the effects of animal-assisted intervention (AAI) on the middle school students' sociability and depression. The participants in this study, 8 middle school students residing in Seoul who were interested in animals and agreed to the research attended this program. This study was conducted two times a week for 6 weeks (a total of 12 times) with one main researcher and three research assistants. The major research tool was the test of sociability and depression and the statistical test being used for this study was Wilcoxon's signed ranks. The results were as follows. First, the study showed the significant effects of animal-assisted intervention on sociability for middle school students. There were significant differences in many aspects such as reliability, autonomy, sociability and compliance. Second, significant reductions in anxiety and depression were found after the introduction of animal-assisted intervention for students. Students who participated this program experienced a reduction in depression and stress to some degree. Also, they began to form much more positive friendships and followed school rules as well. Based on the above results, it can be seen that animal-assisted intervention program significantly has the positive effects on the social adaptability and depression of the middle school students. Therefore, this animal-assisted intervention should be considered as a positive program for emotional and psychological support for middle school students.

The purpose of this study was to determine the health behaviors and nutritional status related to dyslipidemia in Korean middle-aged adults (between 50 and 64 years old) from the Korean National Health and Nutrition Examinations Survey data (2007~2010). A total of 4,721 subjects were analyzed in this study. The subjects were divided into three groups (normal, borderline, and dyslipidemia) according to serum lipid levels. Parameters included in this study were drinking and smoking, anthropometric parameters, blood and nutritional parameters. The latter parameter included food/nutrients intake. All data was adjusted by sex, region, education level, and age. General linear model and logistic regression model were used for statistical analysis. The dyslipidemia group was comprised of more men than women. By contrast, the borderline group was comprised of more women than men (p<0.001). No significant differences were observed for other general characteristics. There were more smokers and drinkers(drinking per time) in the dyslipidemia group (p<0.05). Anthropometric data showed significant difference, ie, height (p<0.05), weight, body mass index, waist circumference, percent body fat, and blood pressure were higher in the dyslipidemia group (p<0.001). Only blood urea nitrogen showed no significant difference among groups. The HbA1c (p<0.01), fasting blood glucose, GOT, GPT, creatinine levels were higher in the dyslipidemia group (p<0.001). So it is required for the management of obesity in dyslipidemia group. The dyslipidemia group ate less sea food (p<0.05). The nutrients intake of energy and protein, thiamin, riboflavin, niacin, calcium, phosphorus were lower in the dyslipidemia group (p<0.05). Therefore, to lower dyslipidemia prevalence rates, it is necessary to increase the intake of foods containing ω-3 fatty acids. We also suggest a meal management program and nutritional education to recognize the risk of dyslipidemia, especially for people such as the individual in the borderline and dyslipidemia study groups. Key words: dyslipidemia, Korean middle-aged adults, nutritional status, health behaviors

This study examined the reading passages of the National Assessment of Educational Achievement (NAEA) and middle school English textbooks in terms of their readability and lexical difficulty. The readability was measured by using Flesch-Kincaid Grade Level Index, while their lexical difficulty was measured in terms of STTR (standardized type-token ratio), frequency of tokens per type, and vocabulary frequency levels by using VocabProfile and Oxford WordSmith Tools 7.0. The results showed that there was a gap between the readability of the English textbooks and that of the NAEA conducted from 2012 to 2014, while the readability between the English textbooks and that of the 2015 NAEA reached a comparable level. However, the textbooks from one publisher showed substantively lower readability than those from the other publishers and the NAEA. Secondly, regarding vocabulary frequency levels, the words in 1K and 2K accounted for more than 90% of the textbooks and the NAEA, while the NAEA had a higher STTR and lower frequency of tokens per type than the textbooks. It suggests that the NAEA employed more various words with less repetition than the textbooks. Pedagogical implications are discussed.

The objective of this study was to compare the differences between males and females in the mediating effects of academic failure tolerance on the impact of self-efficacy on game addiction among adolescents. The results are summarized as follows. First, in both men and women, self-regulation, one of sub-variables of self-efficacy, had negative effects on game addiction. Second, in men, both emotion and behavior had negative effects on game addiction, while, in women, only behaviour did so. Third, among sub-variables of self-efficacy, in males, self-regulation and task difficulty had positive effects on academic failure tolerance, while, in women, self-regulation, confidence, and task difficulty did so. Fourth, testing the mediating role of academic failure tolerance in the effect of self-efficacy on game addiction showed that there was a partial mediating effect among males, while there was a perfect mediating effect among females. All this implies that there is a need to develop programs that help students maintain positive emotions and behaviors even after they have experienced academic failure, considering the importance of academic failure tolerance for students.

본 연구의 목적은 공동생성적 대화가 인식론적 측면에서 학습자의 과학 모델에 관한 이해와, 실행 과정의 측면에서 모델 구성에 미치는 영향을 살펴보는 것이다. 서울 소재 여자중학교 1학년 49명의 학생들에게 총 5차시 모델 구성 수업을 실시한 후 공동생성적 대화에 참여한 2개 조(8명)의 학생들과 참여하지 않은 2개 조(9명)의 학생들의 모델에 관한 이해와 모델 구성을 비교하였다. 모델에 관한 이해는 Upmeier zu Belzen and Krüger (2010)의 분석틀을 사용하였고, 모델 구성 과정은 Baek et al. (2011)의 분석틀을 수정 및 보완하여 분석하였다. 그 결과 전반적으로 공동생성적 대화에 참여한 학생들은 그렇지 않은 학생보다 과학적 모델에 관한 이해와 모델 구성 수준이 높게 나타났다. 공동생성적 대화에 참여한 조의 학생들은 모델을 새로운 현상을 설명할 수 있는 가설로 인식하였지만, 참여하지 않은 조의 학생들 은 모델을 현상을 이해하는 수단으로 인식하였다. 본 연구는 학생들의 모델 구성 과정을 측정하는 분석틀을 마련하여 학교 현장에 유용하게 사용할 수 있게 하였다. 또한 새로운 학습 방법으로써 공동생성적 대화를 모델 구성 수업에 적용했다는 점에서 의의가 있다.
