Melon fruits are a year-old plant in the family Cucurbitae and are the most cultivated fruit in tropical countries. Melon flesh is an important source of anti-cancer, antioxidant effects, attracting attention as a functional food. We investigated the morphological properties, β-carotene content, and cucumisin activity of seeds of 58 melon genetic resources. Melon resources have shown various morphological properties. Melons grouped by morphological properties were the five groups. β-carotene content varied between 82.34 ㎎/㎏, 86.75 ㎎/㎏, 25.56 ㎎/㎏, 86.25 ㎎/㎏, and 54.65 ㎎/ ㎏. Between β-carotene, cucumisin activity and other quantitative fruit morphological properties, the color of the pulp and the firmness of the pulp had a significant amount of correlation between the β-carotene content. However, cucumisin activity and β-carotene content had significant negative correlation, and the color of the fruit and shape of the fruit had significant negative correlation with β-carotene content and activity of cucumisin. Our study vindicated that high diversity in melon morphological characters of genetic sources that provide beneficial baseline data for the future and in the activity of β-carotene and cucumisin, and these results could predict indicators of β-carotene content by the length of leaf, the width of fruit, the length of joint, and the length of seed, and collectively the morphological properties of melons could help predict indicators of β-carotene content and help develop functional sarcoma and farmhouse cultivation.

본 연구는 빠르게 변화하는 사회와 새로운 환경에 대한 다양한 적응적 요구로 증가하고 있는 아동의 스트레스와 이로 인해 발생하는 우울·불안 등의 정서적 적응, 그리고 정서적 적응의 개인차를 설명해주는 요인으로서 자아탄력성에 관심을 갖고 시작되었다. 이에 본 연구에서는 초등학교 아동의 자아탄력성의 구성요소를 확인하고 자아탄력성이 정서적 적응에 미치는 영향을 검증하고자 하였다. 이를 위해 전국의 초등학교 4학년 학생 중 연구대상으로 선정된 동일학 학생을 대상으로 매년 1회 조사를 실시하는 한국청소년패널조사(Korea Youth Panel Survey) 2차년도(2005년 초등학교 5학년 학생을 대상으로 실시) 패널데이터 자료를 활용하여 구조방정식 모형으로 분석하였다. 연구 결과 첫째, 자아탄력성은 대인관계, 자아지각력, 정서조절의 세 가지 요소로 구성되었으며 둘째, 아동의 자아탄력성은 정서적 적응에 부정적인 영향을 미치는 것으로 나타나 자아탄력성이 높은 아동일수록 정서적 적응으로서 우울·불안이 낮은 것으로 나타났다. The present study started with interest in increasing elementary school children's stress due to rapidly changing society and adaptable needs to new environment, emotional adaptation including depression and anxiety resulted from it and ego resilience as factor that explain a difference between individuals of emotional adaptation. Accordingly this study tried to identify constituent factors of ego resilience and verify the effect of ego resilience on elementary school children's emotional adaptation. In order to verify hypotheses according to research questions, we used the 2nd year panel data of Korea Youth Panel Survey conducted by National Youth Policy Institute for elementary school fifth graders throughout the nation in 2005. And structural equation modeling was used for analysis. Study results are summarized as follows. First, ego resilience consisted of interpersonal relationship, self perception and emotional control. Second, ego resilience and emotional adaptation had meaningful relations. Ego resilience showed negative relation with emotional adaptation. Therefore, and the higher ego resilience was, the lower emotional adaptation was.
