This study was performed to examine the shelf life and qualities of wet noodle with Morus alba L. root and Curcuma aromatica extracts (MCE) during storage at 4oC. Lightness and redness of wet noodle were decreased with increasing amounts of MCE added in noodle while yellowness was increased. The viable cell and molds count of wet noodle with MCE was reduced about 1~2 ? cycle as compared with control during storage time. Also the TBARS (thiobarbituric acid reactive substance) value of wet noodle with MCE was lower than that of control. Hence the wet noodle with MCE has shown remarkable antioxidation effect. In sensory evaluation, the wet noodle containing the ratio of 2.5:0.02 of M. alba : C. aromatica was preferred than the control. From these results, the addition of 2.5% of M. alba and 0.02% of C. aromatica extracts in wet noodle had a good effect on improvement of preservation and development of quality.

This study was analyzed to search the effect and satisfaction of life environment science camp by grade difference. The targets were elementary school 4~6-year students and middle school 1~2-year students participated in the ‘Life environment science camp’ during 20 July~11 Aug. 2009. Science interests rate of participant students at the camp were 50.7% of elementary school 4~6-year students, 44.3% of middle school 1-year students, 39.5% of 2-year students, and increasing interests in science after the camp were 68% of elementary school 4~6-year students, 63.3% of middle school 1-yearstudents, 54.4% of 2-year students.The effect of the science camp on their school science class were 71.7% of elementary school 4~6-year students, 60.5% of middle school 2-year students, 53.2% of 1-year students. In addition, Intention of rejoining the science camp were 56.4% of elementary school 4~6-year students, 50.6% of middle school 1-year students, 35.8% of 2-year student. However, intention to get a science related job were 43.1% of middle school 1-year students, 40%of elementary school 4~6-year students, 29.6% of middle school 2-year students.

목적: 일반폐기능 검사만으로는 COPD 환자가 실생활에서 겪는 장애정도와 운동 내성의 한계를 예측하는 데는 한계가 있어, 일반폐기능 검사와 운동부하심폐기능 검사를 이용하여 COPD 환자를 중증도별로 하여 각각 분류하고 그 결과를 비교하여, 운동부하폐기능 검사의 유용성을 알아보고자 하였다. 방법: COPD 환자 105명을 대상으로 안정 시 폐기능 검사와 운동부하심폐기능 검사를 시행하였고, 결과는 표준 의학중증도 분류에 의해 categorical statistical comparison으로 분석하였다. 결과: 두 검사에서 COPD 환자 105명 중 오직 44명(42%)의 환자가 일치된 결과를 보였다. 나머지 환자들 중 21명(20%)은 일반폐기능 검사보다 운동부하심폐기능 검사에서 경한 판정을 받았고, 40명(38%)은 운동부하심폐기능 검사에서 더 심한 판정을 받았다. 운동부하심폐기능 검사에서 더 심한 판정을 받은 환자들은 운동부하 검사 심혈관계 지표들이 보다 감소되어 있었다. 결론: COPD 환자의 운동능력은 일반폐기능 검사만으로는 예측하는 데는 한계가 있으며, 전신질환으로서의 COPD 질환을 이해하고 예측하는데 있어 운동부하폐기능 검사도 일부 도움을 주리라 생각되나, 앞으로 좀 더 많은 연구가 필요하리라 사료된다. Background/Aims: Chronic obstructive pulmonary disease (COPD) is characterized by an incompletely reversible airflow limitation. Pulmonary function test (PFT) has been considered the gold standard test for diagnosis and severity evaluation in COPD. However, PFT by spirometry does not provide information about exercise performance in COPD patients. Therefore, the present study was performed to compare pulmonary function determined by spirometry with exercise function determined by cardiopulmonary exercise test (CPET) for grading of COPD. Methods: A total of 105 patients with airway obstruction were examined. The patients` mean age was 65 years, and the mean smoking history was 27 pack-years. The patients underwent spirometry and CPET. The results were analyzed by categorical statistical comparison, based on the Global Initiative for Chronic Obstructive Lung Disease (GOLD) and American Thoracic Society guidelines. Results: The two methods agreed on the classification of only 44 patients (42%). Of the remaining patients, 21 (20%) were found to be less severe according to CPET than according to PFT, whereas 40 (38%) were more severe. Those who were more severe according to CPET had significantly low maximal minute ventilation, low anaerobic threshold, low oxygen pulse, and high breathing reserve. Conclusions: The present study revealed the large disagreement between the results of resting and exercise pulmonary function tests, and therefore suggests the need for a novel approach or guideline. Additional cardiological evaluation may be needed in patients classified as more severe according to CPET, who are assumed to have a greater degree of impairment of cardiovascular function.
