Along with the development of LCA methodology the construction of relevant databases are absolutely necessary for the efficient study of LCA. However, it is recognized that further development of LCA in Korea is currently limited by the lack of available life cycle inventory database on material, energy, process, transportation, and waste treatments. In an effort to solve this problem, the life cycle inventory databases for injection molding processes of polyethylene and polystyrene are established.

<P><B>Objective</B></P><P>Human papillomavirus (HPV) 16 is the most carcinogenic HPV genotype. We investigated if HPV16 L1 capsid protein and E2/E6 ratio, evaluated by cervical cytology, may be used as biomarkers of ≥cervical intraepithelial neoplasia (CIN) 2 lesions.</P><P><B>Methods</B></P><P>Cervical specimens were obtained from 226 patients with HPV16 single infection.

We observed that area under the receiver operating characteristic curve (AUC) for E2/E6 ratio (0.844; 95% confidence interval [CI]=0.793–0.895) was higher than that for L1 immunochemistry (0.636; 95% CI=0.562–0.711).

발달적 측면에서 체육수업 활동이 유아들의 협응력 향상에 미치는 영향
서연태,김종탁 한국유아체육학회 2000 한국유아체육학회지 Vol.1 No.1
본 연구는 체육 수업 활동이 유아들의 협응력에 어떠한 영향을 미치고 있는가를 규명하기 위하여 KTK 과제를 통해 협응력의 중요성을 인식하고, 체육 수업의 활성화를 꽤하는데 있다. 이러한 연구 문제를 해결하기 위하여 4-6세의 유아들을 대상으로 체육 수업에 참여한 유아 90명과 참여하지 않은 유아 90명. 총 180명을 선정하여 자료를 분석한 결과, 다음과 같은 결론을 얻었다. 첫째, 체육 수업에 참여한 유아들이 비참여 유아들에 비해 협응력 요소 전 과제에서 높은 값을 나타냈고, 통계적으로 유의한 차이를 보였다(p<.001). 둘째, 연령별 및 체육 수업 참여 여부에 의한 유아들의 협응력 차이는 평형성, 민첩성, 교치성 등 모든 과제에서 체육 수업에 참여한 유아들이 높은 값을 보였고(p<.05, p<.001), 연령간에 있어서는 평형성 과제 요소인 4.5cm, 6.0cm '되로 걷기'와 '좌우 뛰기' 과제에서 연력과 관계가 있는 것으로 나타났다. 셋째, 체육 수업을 통한 각 과제별 상관관계를 분석한 결과 체육 수업 활동에 참여한 유아들이 비참여 유아들 보다 각 과제별로 높은 상관관계를 보였다. The purpose of this study was to investigate effect of the physical activities in Kindergarten on the coordination of children. For measuring it, KTK was used that has been developed by Kiphard and spread in Germany. 180 children aged 4 to 6 were used as subjects that were assigned to control group and experimental group in each age. The results were as follows: 1) According to the participating in the regular physical activities or not, the children in the experimental group showed higher marks and significant difference in all task (p<.001). 2) According to the difference of the coordination by ages in both groups, the children in the experimental group showed higher marks in all the tasks (p<.05, p<.001), but according only to the ages there was correlation only in the 4.5cm, 6.0cm balancing-backwards-tests of the balance task and in the jumping sideways. 3) According to the correlation of each task, the children in the experimental group showed significant correlation in each task.
