This study was carried out to examine the effects of school safety education on the safety behavior among elementary school students. Sixty-two 4th grade students were sampled from an elementary school in Pohang city and divided into one experimental group and one control group. The safety education has been provided to the experimental group for 4 weeks The data were collected before, just after, and 8 weeks after the education. In the pre-test, the general characteristics and safety behavior between two groups were measured. The experimental group was given school safety education twice a week for 4weeks. They also filled out the self behavior check list. In the post-test and follow up-test safety behavior was collected. The data analysis was done using $X^2$-test. t-test. Repeated measures ANOVA, analysis of simple main effect and time contrast methods, they were processed with an SPSS Win 9.0/pc. The results of this study are summarized as follows: 1) There were no differences between experimental group and control group on the general characteristics and safety behavior in the pre-test. 2) The hypothesis: 'The experimental group which was given school safety education will show higher scores on safety behavior than the control group which was not given this was supported(F=6.43 p=0.01). 3) The subhypothesis 1 : 'The scores on the indoor safety behavior of the experimental group which was given school safety education will show higher than those of the control group which were given this was supported(F=3.59 p=0.03). 4) The subhypothesis 2 : 'The scores on the outdoor safety behavior of the experimental group which was given, school safety education will show higher than those of the control group which was not given this was supported(F=5.70 p =0.00). In consequence, the experimental group which was given school safety education scored higher on safety behavior than the control group. Therefore, school safety education should continue to encourage safety behavior among elementary school students.

Purpose:This thesis was performed to evaluate the effect of the experience safety education on the safety behavior and standard of habit to the middle school students of one islands. Methods:The participants of this study included 43, located in the adjoining region in S county. While one of the class, composed of 19 students was designated as an experimental group, and the other class, composed of 24 students, was compared as a control group. Used program in this study was safety education program, 'Safe School, Safe Life' which was developed by Korea Occupational Safety & Health Agency. This program has emphasis on the virtual case rather than lecture style education. Results:The findings in this research were as follows. Indoor safety behavior was significant difference between the two groups. On the other hand, the effect on outdoor safety behavior was not difference. In playground case, active strength was needed without continuous attention. The effect of the experience safety behavior education was not shown in the area of traffic rules, pedestrian safety, and vehicle safety. But home safety behavior was effective. Education program on the manners of standard life habit gives positive results. But in the area of rules, this program was not effective, since students had tendency to emphasize the rigid scale rather than manners. Conclusion:These findings in the study give us the necessity of experience safety education program to prepare various situations of everyday life and to reinforce safety behavior and improve standard life habit.

본 연구에서는 일반아동과 자폐아동 모발의 무기질, 유해중금속 함량, 혈액의 자유라디칼 및 세로토닌 함량을 측정함으로써 일반아동에 대한 자폐아동의 특성을 연구하고자 하였다. 실험그룹은 3~9세 사이의 50명의 아동을 일반아동(22명) 및 어린이 정신과 의사에 의해 판정된 자폐아동(28명)의 두 그룹으로 나누었다. 일반아동과 자폐아동 간의 나이, 신장, 체중 및 식이섭취량은 두 군간 유의적인 차이가 없었으나, 모발 중 다량미네랄 함량을 측정한 결과 Ca, Mg, P 및 S는 일반아동이 자폐아동보다 다소 높게 나타났으며, Na 및 K는 자폐아동에서 일반아동에 비해 유의적으로 높았다. 또한, 모발 중 미량미네랄 함량을 측정한 결과에서는 Cu, Zn, Fe, Cr 및 Se는 일반아동이 자폐아동보다 높게 나타났으며, 특히, Cu, Zn, Fe의 경우 두 그룹 간에 유의적인 차이를 나타내었다. Mn, B, Co 및 Mo는 두 그룹 간에 차이가 없었다. Al의 경우에는 자폐아동에서 더 높은 것을 관찰할 수 있었으나 유의적인 수준은 아니었다. 일반아동 및 자폐아동의 모발 중 유해중금속 함량을 측정한 결과 As, Hg 및 Be의 경우에는 두 그룹 간에 유의적인 차이를 나타내지 않았으나 Cd와 Pb는 일반아동에 비해 자폐아동에서 유의하게 높은 것을 관찰할 수 있었다. 혈액 내 자유라디칼 함량은 자폐아동이 일반아동에 비해 유의적으로 높게 나타났으며, 세로토닌 함량은 일반아동과 자폐아동 간의 유의적인 차이가 없었다. 이상의 결과 본 연구에서는 식이섭취량을 단 하루만을 조사하였으나 향후에는 조사기간을 더 늘리고 식품섭취유형과 패턴 및 식행동 장애 분석 등 좀 더 다양하고 깊이 있는 연구가 진행되어야 할 것이다. 또한 자폐아동은 일반아동에 비해 모발의 일부 미네랄 함량은 감소, 중금속 함량의 증가 및 자유라디칼 생성이 증가함으로써 자폐아동의 행동 및 발달장애에 영향을 미치는 것으로 사료된다. 향후 연구에서는 자폐아동에게 부족한 영양소의 보충 및 중금속 해독 영양소를 섭취함으로써 자폐아동의 행동 및 발달장애의 개선 기능에 대한 연구가 시행되어야 할 것이다. The purpose of this study was to test characteristics between normal and autistic children via comparison of nutrient intakes, hair mineral, blood free radical, and serotonin contents. A total of 50 children aged 3-9 were divided into two main groups of normal control children (n=22) and autistic children (n=28) tested by child psychiatrist. The nutrient intakes by 24-hour recall method were no significantly different between the two groups. The concentrations of toxic mineral, such as cadmium (Cd) and lead (Pb) in hair of autistic children were significantly higher, while concentration of antioxidant mineral (Cu, Zn, Fe) was lower than that of normal children. The autistic children had significantly higher concentrations of blood free radical than that of normal children. No significant difference was observed in serotonin concentration between the two groups. Our results suggest a possible role of increased toxic mineral and free radical, both of which may be relevant to the pathophysiology of autism in children with developmental delay.

The purpose of the present study was to evaluate the characteristics of nutrient intakes of adults aged 20-64 years in Daegu and Gyeongbuk areas in comparison with Seoul and the whole nation. Data from the 1st (1998) to 3rd (2005) Korean National Health and Nutrition Examination Survey (KNHANES) were used. Total numbers of subjects were 296-369 from Daegu and 307-447 from Gyeongbuk while 1076-1244 from Seoul and 5436-6852 from the whole nation. Average energy intakes (men; 2,386, 2,581, 2,305 Kcal, women; 1,937, 1,981, 1,804 Kcal in 1998, 2001, 2005, respectively) of the subjects from Daegu were higher than those from Gyeongbuk (men; 2309, 2267, 2487 Kcal, women; 1,851, 1,845, 1,901 Kcal) and those from Seoul in 1998 and 2001 but not different from those in 2005. Energy from carbohydrate was consistently higher in the subjects from Daegu and Gyeongbuk than in those from Seoul from 1998 to 2005, when the subjects whose carbohydrate energy was over 70% comprised 34 to 58% of the total in the two regions. In 2005, the average intakes of calcium of women and men from Daegu were 512 and 573 ㎎, iron, 12.8 and 16.6 ㎎, sodium, 4,650 and 5,951 ㎎, potassium, 2,585 and 3,152 ㎎, vitamin A, 823 and 1,038 ㎍RE, thiamin, 1.10 and 1.43 ㎎, riboflavin, 1.08 and 1.33 ㎎, and niacin. 15.4 and 19.3 ㎎, and vitamin C, 94 and 105 ㎎ and these intakes were not very different from those from Gyeongbuk except higher sodium intake of the Gyeongbuk subjects. Nutrients of which the intakes were over 50% lower than EAR were calcium and riboflavin and those about 30% lower than EAR were iron in women, vitamins A and C in men and women from Daegu and Gyeongbuk. From the present results, it is concluded that high dependence on carbohydrate as energy source and low calcium intake in adults of Daegu and Gyeongbuk are serious and that low intakes of riboflavin, iron and vitamins A and C need to be improved. But changes in the intakes of total energy and other micronutrients from 1998 to 2005 were not reliable enough to judge the regional nutrition due to large variations during this period. The present study also provides the adults’ nutrient intakes separated by sex and age groups in the three regions which could be readily used for setting up the nutrition policy for the adults in the regions.

스마트그리드의 안전성과 보안 이슈

최근의 전력난, 일본 후쿠시마 원전사태 등은 전력생산이 상대적으로 적은 나라에게는 큰 부담이 아닐 수 없다. 이러한 배경에서 스마트그리드라는 지능형 전력망의 개념이 도입되었고, 우리나라도 녹색성장에 힘입어 적극 추진하고 있다. 그러나, 스마트그리드에도 소규모 분산 전원공격, 양방향 통신 프로토콜 공격, 배전망 관리센서 공격, 보안에 취약한 스마트미터에 대한 공격 등의 사이버공격이 이루어지고 있어 전력 공급은 물론 전체 시스템에 타격을 줄 수 있다. 본 논문에서는 이러한 보안 체계에 대한 요구 사항을 정리하고, 안전성이 보장하기 위하여 필요한 이슈를 제기하고자 한다.
