국내에서 생산되는 시판올리고당들(IMO, FO 또는 GO)이 쇠고기 단백질에 냉동 및 저장시 변성 방지효과에 대한 실험결과를 sucrose 및 sorbitol과 비교해보았다. 신선한 쇠고기육에서 액토마이오신을 추출하여 시판 올리고당들 및 sucrose를 각각 농도별(0~12%)로 혼합 후 냉동-해동을 반복하여 약 8%가 적정 사용농도임을 확인하였다. 냉동저장 중 액토마이오신의 변성 방지효과를 알아본 결과, 대부분의 시판 올리고당들은 무첨가군보다는 높은 변성 방지효과를 보였으며, 올리고당들 중에서는 GO와 FO가 단백질 변성 방지효과가 큰것으로 나타났다. 기존에 밝혀진 냉동변성 방지효과가 높은 당들과의 비교에서는 sucrose+sorbitol보다 높은 변성 방지효과를 보였으며 sucrose보다 다소 낮거나 유사한 효과를 보였다. A study was conducted to investigate cryoprotectant effect of commercially produced oligosaccharides (IMO: isomalto-oligosaccharides, FO: fructo-oligosaccharides and GO: galacto-oligosaccharides) on beef protein and to compare their effectiveness to sucrose or a mixture of sucrose and sorbitol on freezing. The optimal addition level of cryoprotectants was determined by measuring Ca^(2+)-ATPase activity of sample treated with different concentration (0 to 12%) after freeze-thaw cycle. Since the stabilization effect was not dramatically increased above 8% sugar concentrations, the 8% was determined as an usage level. During frozen storage (at -18℃ for 12 week), commercially produced oligosaccharides showed lower cryoprotection ability than sucrose but higher than sucrose+sorbitol as measured by protein solubilities and Ca^(2+)-ATPase activities.

본 연구는 중·노년여성들을 대상으로 24주간 한국무용을 이용한 춤체조프로그램을 적용하여 이들의 체력 및 신체구성, 골밀도와 활동량 등에 미치는 영향을 알아보는데 그 목적을 두었다. 본 연구에서 중·노년여성 34명을 무작위로 배정하여 실험집단 15명을 대상으로 한국무용을 이용한 춤체조프로그램을 24주간 실시하였으며, 비교를 위해 14명을 통제집단으로 배정하였다. 중·노년여성의 1일 에너지소비량의 약 10% 정도에 해당되었다. 이상의 결과는 한국무용을 이용한 춤체조가 근육을 리드미컬하게 사용하고 운동강도가 높지 않아 중·노년여성들이 우리의 전통 가락을 즐기면서 체력과 건강상태를 향상시키는 데 훌륭한 수단이 된다고 사료된다. The purpose of this study was to investigate effects of 24-week calisthenics using Korean traditional dance on functional fitness and bone mineral density in aged women. Twenty-nine women (42-64yrs) were randomly divided into two groups(TG; 15, CG; 14). The program was carried out 2 times a week for 80 minutes during 24 weeks. The result showed that the 24 weeks` calisthenics using Korean traditional dance has positive effects on body weight, %body fat, muscle endurance and flexibility. BMD showed tendency of reducing in control group, but was indicated to be increased slightly in the training group. The energy consumption for 80 minutes of exercise was 185.46±42.50 ㎉, it meant that would be applicable to about 10% of recommended dietary allowance in aged women. In conclusion, 24 week Korean traditional dancing affected positively to the improvement of functional fitness, bone density of old aged women. Exercise intensity and energy consumption level was also appropriate.

To mitigate the impacts of climate change on agricultural ecosystems, development of agricultural management for enhanced soil carbon sequestration is required. In this study, the effects of fertilizer types (chemical fertilizer and manure compost), cropping systems, and crop residue management on SOC(Soil Organic Carbon) sequestration were investigated. Summer corn and winter barley were cultivated on experimental plots under natural rainfall conditions for two years with chemical fertilizer and manure compost. Soil samples were collected conducted and analyzed for SOC for soil. To estimate long-term variation patterns of SOC, DNDC was run with the experimental data and the weather input parameters from 1981 to 2010. DNDC simulation demonstrated SOC reduction by chemical fertilizer treatment unless plant residues are returned; whereas compost treatments increased SOC under the same conditions and SOC increment was proportional to compost application rate. In addition, SOC further increased under corn-barley cropping system over single corn cropping due to more compost application. Regardless of nutrient input type, residue return increased SOC; however, the magnitude of SOC increase by residue return was lower than by compost application.

Purpose: This study was done to explore the correlation among mobile phone overuse, mental health and school adaptation, and to identify factors related mobile phone overuse. Methods: A questionnaire was filled out by 943 elementary school students from 3rd to 6th grade in the cities of Busan and Ulsan. Frequency, percentage, mean and standard deviation, t-test, ANOVA, Pearson`s correlation coefficients and stepwise multiple regression with SPSS/WIN 12.0 program were used to analyze the collected data. Results: Mobile phone overuse in the elementary school students was positively correlated with mental health, and negatively correlated with school adaptation. Stepwise multiple regression analysis showed the factors as school grade, gender, depression, anxiety, learning adaptation, adaptation to friends and adaptation rules significantly accounted for 23% of the variance for mobile phone overuse. The most significant factor influencing overuse of mobile phone was school grade. Conclusion: These results suggest that early screening and intervention programs for students with low mental health and low school adjustment would be helpful in preventing future mobile phone overuse.

Purpose: The purpose of this study is to find out the correlation between internet addiction and school adjustment of 3rd and 4th graders in elementary schools. Methods: The subjects were 689 graders from five schools in five districts, located in G, Korea and the data were collected from April 18 to May 15, 2005. A scale consisting of 25 questions were developed as an instrument for testing internet addiction and a further 25 questions were developed for examining school Adjustment. The data was analyzed by testing frequency, percentage, means, standard deviation, t-test, ANOVA, Scheffé test and Pearson's Correlation using SPSS/PC 10.0. Results: The results were as follows: The degree of internet addiction tendency were 6.0% of addiction, 24.2% of borderline and 69.8% of non-addiction. There were significant differences in school adjustment in terms of the degree of internet addiction(F=39.88, p< .05) and significant negative correlation between the degree of internet addiction and the school adjustment; the more they used to the internet, the lower school adjustment they have(r=- .376, p< .05). Conclusion: Those graders who started using the internet at an earlier age, were found to have increased levels of internet addiction. therefore, it is necessary to develop a program for the prevention of internet addiction and a school adjustment education program is recommended for that.

본 연구에서는 3;0 - 6;11세, 정상아동 총 112명을 대상으로 생성이름대기 능력의 발달을 알아보았다. 이를 위해 의미(동물, 가게 물건) 및 음소(/ㄱ/, /ㅂ/) 범주에 따른 산출 낱말을 양적인 측면에서, 또한 군집(clustering)과 전환(switching)이라는 기준을 통한 질적인 측면에서 살펴보았다. 연구 결과 첫째, 연령이 증가함에 따라 의미 및 음소범주의 총 낱말산출 개수가 유의미하게 증가하였다. 둘째, 범주 별 낱말산출 시 연령이 증가함에 따라 동일한 하위 범주 내의 낱말을 연속적으로 산출하는 ‘군집’과 하위 범주 간 이동을 통해 낱말을 산출하는 ‘전환’의 개수도 아울러 증가하였다. 셋째, 의미범주의 생성이름대기에서 남아는 ‘동물’항목에서, 여아는 ‘가게 물건’항목에서 더 많은 낱말을 산출했다. 넷째, 음소범주의 생성이름대기의 경우, 아동들의 읽기능력과 낱말산출 개수 간에 밀접한 상관이 있었으며 읽기 능력의 개인 편차가 큰 어린 연령 대에서 이 상관은 더 높게 나타났다. 본 연구는, 생성이름대기 검사가 연령별 발달을 보여주는 지표로 사용될 수 있음을 보여주고 있으며 또한 이 시기 아동들의 경우 읽기 발달 수준이 음소범주 생성이름대기 능력에 영향을 미치는 것으로 나타나 이 항목의 경우 읽기 능력의 차이가 평준화되는 학령기에 시행하는 것이 필요함을 보여주었다. The purpose of this study was to examine the development of generative naming ability for 112 normal Korean children aged 3, 4, 5 and 6 years. In this study, we investigated how naming ability is developed through clustering and switching; these are the criteria for quantitative and qualitative analysis of words produced by children of this age group, since they show an explosive development of their vocabulary. The following results were obtained: 1. With increasing age, the total number of words produced was significantly increased according to generative naming ability, as was measured with a semantic fluency test and a phonemic fluency test. 2. With increasing age, semantic and phonemic fluency tests contained within the generative naming test showed significant increases for the frequency of clustering and switching. 3. In the semantic fluency test, boys performed better than girls in the ‘animals’category, whereas girls came up with significantly more words in the ‘items in stores’category. 4. In the phonemic fluency test, a significant correlation was shown by these age groups for reading ability and word production. This correlation was very significant for younger children whose reading ability was individually different. 5. As the frequency of phonemes was high, as provided in the generative naming according to the phonemic fluency test, so the number of words produced was also high. These results showed that generative naming ability is increased significantly in preschool age children, i. e., 3, 4, 5 and 6-year-old children. This increase is due to the use of clustering and switching. Generative naming according to a phonemic fluency test showed a significant correlation in reading ability and the extent of word production. Thus, the phonemic fluency test of the generative naming test is needed for children at the age when reading abilities are equalized.
