참여형 과학문화 확산의 일환으로 지속되어 온 생활과학교실은 효과적인 학교 밖 체험·탐구 활동으로서 과학의 대중화에 앞장서왔다. 그러나 최근의 코로나19 상황으로 생활과학교실 역시 비대면으로 전환하거나 대면-비대면 교육을 조합할 수밖에 없는 환경이 되었으며, 이러한 교육의 변화가 여전히 학생들의 과학에 대한 관심과 흥미를 제고하는데 효과적인지 검토가 필요한 시점이다. 이에 본 연구에서는 비대면 생활과학교실 프로그램에 참여한 초등학생들의 평소 관심 분야, 과학기술에 대한 인식, 과학에 대한 관심과 흥미, 과학적 역량이 어떻게 변화되는지 확인하고 학생과 학부모들의 인식 차이를 비교함으로써 비대면 생활과학교실의 교육 효과성을 제고하고 향후 운영 방안에 대해 모색하였다. 연구 결과 비대면 생활과학교실 프로그램 참여 이후 학생들은 과학기술 발전이나 미래기술, 환경오염, SNS에 대한 관심 등이 높아지고 게임에 대한 관심이 줄어드는 경향을 보였다. 또한 과학기술 활동에 대한 관심, 과학에 대한 흥미, 과학적 역량도 증가하여 비대면 생활과학교실의 교육 효과를 확인할 수 있었다. 이를 바탕으로 생활과학교실의 학습 주제와 내용 수준을 다양화하고 소외된 학습자들에게 비대면 과학 학습의 기회를 확대하며, 최신 미디어를 활용한 과학콘텐츠 개발과 공유가 필요함을 제언하였다.

This study was performed to investigate the interrelationship between fasting serum insulin, eating behaviour, daily energy intake and the fatness in obese and non-obese women. The possibility of fasting serum insulin as potential predictive factor for eating behaviour and daily energy intake was also investigated. The results are as follows: 1) In obese women ; Subjects with higher fasting serum insulin were associated with higher speed of eating and shorter meal duration time. No association could be found between daily energy intake or the degree of obesity and fasting serum insulin. There was a significant positive correlation between obesity, daily energy intake and speed of eating. Obesity, daily energy intake were negatively related to meal duration time. Subjects with a rapid speed of eating were apt to overeat during eating behaviour experiment. Our findings suggested that a rapid speed of eating is a contributing factor to the development of obesity in obese women. 2) In non-obese women ; While subjects with higher insulin level were apt to overeat, we could not find any relation between overeating and daily energy intake. There was no correlation between eating speed and daily energy intake, but a significant positive correlation was found between meal duration time and daily energy intake. The degree of fatness was increased with the lower daily energy expenditure per body weight, or the higher waist hip girth ratio, fasting serum insulin and daily energy intake.

The physical dependence potency of DA-5018, a non-narcotic analgesic agent, was tested in mice dosed with 0.5 and 4 mg/kg/day for 2 months and daily increasing doses of 1, 2, 4, 6, 8 and 10 mg/kg over 10 days. Physical dependence was assessed taking natural withdrawal induced morphine-type abstinence (jumping, falling, biting or backward locomotion, rearing etc.) as well as barbiturates-type abstinence (body weight reduction, convulsion, ataxia etc.) into consideration. The results were compared with those after the same daily increasing doses of morphine. DA-5018 did not show evidence of physical dependence liability or abuse potential as measured by morphine-type or barbiturate-type abstinence signs following daily increasing or 2-month repeated administration. On the other hand, daily increasing doses of morphine produced physical dependence and the dependent state disappeared about 6 hours after the start of withdrawal signs. In the single dose suppression test, a single dose of morphine completely suppressed natural withdrawal signs that appeared in morphine-dependent animals. Therefore, these results indicate that DA-5018 does not have abuse potential and physical dependence liability.

This study investigates the relationship of smoking on daily intake of nutrients and snacks in the Chungnam and Daejeon high school students. Up to date scientific nutrition education and counseling programs in the regular school system is needed for a professional nutrition education teacher. The primary objective of this study was to provide useful information to nutrition education teachers. A survey was conducted with 400 high school students in the Chungnam and Daejeon areas. 381 out of 400 questionnaires were analyzed with SPSS 12.0K. The subjects were composed of 49.8% male, 50.1% female and 40.9% regular high school students, 59.1% business high school students and smokers 43.1%, non-smokers 56.9%. 43.4% of smokers had been smoking since middle school. On analysis of daily nutrient intakes, 16 out of 19 nutrients except animal calcium, Vitamin A and Vitamin C were much more consumed by the smoking group than the non-smoking group non-significantly. Especially vegetable fat and Vitamin E were higher in the smoking group than the non-smoking group (p<0.05). The intake ratio of carbohydrates: protein: fat was similar in the two groups (smoking group 55:15:29, nonsmoking group 56:15:28). Intakes of Vitamin B1 and potassium in comparison with the Korean dietary reference intakes(KDRI) were under 50% in both groups. However, sodium was taken over 200% compared to KDRI in both groups. Intakes of Vitamin C in the smoking group were as low as 76.5% in comparison to KDRI. Smokers need to increase the intakes of Vitamin C considering that smokers need to intake Vitamin C two times than non-smokers. Nutrient intakes from snacks in the smoking group were higher than the non-smoking group. Nutrients that originated from snacks which took over 20% among daily nutrient intakes were 12 nutrients(energy, fat, carbohydrate, calcium, P, Fe, K, Vitamin $B_1$, Vitamin $B_2$, Vitamin C, Vitamin E, dietary fiber) in the smoking group compared to 7 nutrients(energy, vegetable protein, fat, carbohydrate, calcium, Vitamin $B_2$, Vitamin C) in the non-smoking group. The smoking group was significantly paying more money for snacks each month than the non-smoking group was(p<0.01). Periods of consumption were irregular in the smoking group(p<0.05) and the smoking group was used to taking snacks in the morning compared to the non-smoking group. The smoking group preferred sweets and high calorie food over other snacks in comparison of the non-smoking group. The nonsmoking group had better eating habits than the smoking group.

The purpose of this study was to assess the daily steps, physical activities and activity coefficient of the elementary school children in the rural area. Body weight, height and daily steps were measured and one-day activity diaries were collected by interviewing children. The average age of the subjects was $9.96{\pm}1.02$ years. Average height, weight, obesity index, body fat and muscle of subjects were $136.2{\pm}8.9cm,\;35.2{\pm}8.5kg,\;99.6{\pm}18.8%,\;22.9{\pm}8.5%\;and\;35.8{\pm}6.0%$, respectively. The average daily steps of the subjects was 17,584 and daily steps (19,314) of 3rd grade students was significantly higher than that (15,712) of 5th grade children. But there was no significant difference in daily steps and activity coefficients between boys and girls. Daily steps (23,347) of exercise group showed the significantly higher than that (16,144) of non-exercise group. Gender and grade of subjects did not have significant influence on activity coefficients, but there was a significant difference in activity coefficient on weekdays between the exercise group ($1.82{\pm}0.30$) and non-exercise group ($1.50{\pm}0.21$). Analysis of variance revealed stronger associations between daily steps and body fat (%) than between daily steps and BMI. Daily steps showed significant negative correlation with body fat (%) measured using two methods r=-0.321 and r=-0.365, respectively. Activity coefficient was significantly correlated (r=0.436) with daily steps, thus increasing daily steps cm prevent and treat childhood obesity by increasing the energy expenditure. The higher activity coefficients (weekday 1.56, weekend 1.53) of the subjects was caused by the fact that rural students spent more time outside and enjoyed stronger activities than urban students. The results of this study can be used to estimate energy requirements for Korean children based on exercise levels and living areas.

Load Duration Curve(LDC) is a useful tool for analyzing water quality characteristics under various stream flow conditions. This study investigated the methods to identify impaired waterbodies in the assessment of water quality goal attainment by using LDC for the management of Total Maximum Daily Loads (TMDLs). Three methods were proposed. Non-typical regime exclusion method is a method to exclude water quality observations in the non-typical extreme flow conditions in order to minimize the influence of non-ordinary water quality. Flow regime weighted average method is a method to calculate weighted mean water quality instead of arithmetic mean in order to consider water characteristics properly on stream flow regime in addition to the effect of Non-typical regime exclusion method. Load exceeded interval comparison method is a method to compare the intervals between the attained and non-attained load duration periods on the LDC. The assessment of water quality goal attainment can be performed more reasonably and precisely considering water quality variations on stream flow conditions by applying these proposed methods.

Purpose: This study was conducted to study the acceptance of disability and influential factors between hemiplegic elderly and non-elderly after stroke. Methods: Data were collected with questionnaires from 104 elderly and 134 non-elderly with hemiplegia. Data were analyzed by $x^2$-test, t-test, ANOVA, ANCOVA, Pearson correlation coefficient, and multiple regression. Results: Significant predictors of acceptance of disability were family support, activities of daily living, and age, and these factors accounted for 24.2% of variance in acceptance of disability in the hemiplegic elderly. On the other hand, the significant predictors were family support and employment, and these factors accounted for 32.3% of variance in acceptance of disability in the non-elderly. Family support was the most influential variable in both the elderly and the non-elderly. Conclusion: An acceptance of disability program for the hemiplegic elderly should be designed differently from that for the non-elderly.

Purpose: This survey was to investigate the differences in smartphone addiction symptoms by the level of addiction among college students in S. Korea. Methods: Two hundred and thirteen university students survey data was collected from December 5th to 9th of 2011 using Smartphone Addiction Scale. 25.3% (n=54) of total respondents were categorized as highly addicted and 28.17% (n=60) were as non-addicted group. Results: There were significant differences in total addiction symptom scores, daily life disorders, loss of self control, pathological concentration, and compulsive symptoms between two groups. There were significantly differences in total addiction symptoms, daily life disorders, loss of self control, pathological concentration, and compulsive symptoms between two groups. Highly addicted group were significantly higher in total addiction symptom scores (3.26 times), daily life disorders (4.96 times), loss of self control (3.07 times), pathological concentration (3.07 times), and compulsive symptoms (2.86 times) compared to non-addicted one. Highly addicted group had significantly higher daily usages of smartphone and were more satisfied with smartphone than non-addicted group. The purpose to use was related to academic works rather than games or entertainment. However satisfaction on academic achievement was very low. Conclusion: The smartphone addicted symptoms related to academic works were significantly high in highly addicted college students so that it disturbed their daily life and psycho-social health in general. It is clear that the highly addicted college students need urgent distinctive interventions such as creative academic guides.

Although surgery is the mainstay of local treatment for skin cancer, definitive radiation therapy (RT) has been also applied for patients who are unable to tolerate surgery. Definitive RT regimens usually consist of daily treatment for 4-7 weeks. Such protracted daily RT regimens, however, would not be feasible for non-compliant patients or patients who are unable to make multiple daily trips for weeks. Without treatment, however, skin cancers can continuously progress and cause distressing symptoms. A cyclical hypofractionated RT (QUAD Shot: 14 Gy in 4 fractions, twice-daily treatments with 6 hours interval on 2 consecutive days) can be a practical RT regimen for those patients. In this report, we present the successful treatment course of repeated QUAD Shots in a 79-year-old patient with neglected skin cancer that was disfiguring his face yet declined definitive surgery and protracted RT. We also evaluated and compared biologically equivalent doses between QUAD Shots and conventionally fractionated protracted RT regimens.
