본 연구의 목적은 현재 교사 대 유아 비율이 높은 우리나라의 유아교육기관에서 교육활동의 효율성을 위해 몇몇의 유아들을 단순히 소집단으로 나누어 여러 가지 교육활동을 하고 있어 진정한 의미의 협동학습이 이루어지지 않고 있는 실정을 고려하여 Learning together 협동학습 모형에 기초한 수학활동이 유아의 측정능력에 미치는 영향을 살펴보고자 하였다. 본 연구는 2013년 4월부터 2013년 7월 초까지 진행하였으며, 연구 대상은 충남에 소재한 B유치원의 만5세 유아 50명(실험집단 25명, 통제집단 25명)을 대상으로 하였다. 본 연구 결과를 요약하면 다음과 같다. 첫째, Learning together 협동학습 모형에 기초한 수학활동은 유아의 측정기술 중 비표준 단위를 이용한 측정하기 능력에 긍정적인 영향을 미치는 것으로 나타났다. 즉 ‘비표준 단위를 이용하여 길이, 넓이, 부피, 무게 측정하기’에서 측정능력이 향상된 것이다. 둘째, Learning together 협동학습 모형에 기초한 수학활동은 유아의 측정기술 중 직접 비교하기와 비표준 단위 선택 능력에 영향을 미치지 않은 것으로 나타났다. 즉 직접 비교하기와 비표준 단위 선택하기에서 길이, 넓이, 부피, 무게 4개 영역 모두 효과가 나타나지 않았다. This study aims to examine the effects of mathematical activity based on cooperative learning model of Learning Together on the measuring ability of the young children s Study subjects were established in the following procedure. Out of 50 5 year-old young children s enrolled at B kindergarten located at Chungnam, 25 young children s were allocated into the experimental group and 25 young children s into the control group. Examination tool used for this study was ‘Measuring Ability Test Tool’ of Hee Young Jeon (2001). Preliminary test was carried out with 25 young children s in experimental group and 25 young children s in control group. To examine the measuring ability of control group who received planned education activities and that of experimental group who received mathematical activities based on the cooperative learning model of Learning Together, I carried out t-test and χ2 test for comparison of preliminary test and post-test between groups, and utilized SAS 9.2 program for this. Conclusion of this study is as follows. First, mathematical ability based on cooperative learning model of Learning Together was found to have positive effects on the ability of young children to measure using non-standard unit among measuring skill of young children s Second, mathematical ability based on cooperative learning model of Learning Together was found not to influence the ability to directly compare and to select the non-standard unit among measuring skill of young children s In light of this, mathematical ability based on cooperative learning model of Learning Together was found to have positive effects on ‘ability to measure using non-standard unit’ among measuring ability of young children s Since this ability requires thoughts more difficult than the ability to directly compare and to select non-standard unit, mathematical activity based on cooperative learning model of Learning Together can be regarded to have positive effects on measuring ability of young children s.

In European countries or Japan they made an attempt for the standardization of assays in AST, AL T, ALP, CK, ill and GGT 10 years ago. For the actualization of the trial, they managed to succeeded in development of certified reference material and enzyme reference material. And they are now forecasting the unification of test results produced differently urder the respective situatons. Then, throogh the highly developed communication system, someone can access any test results whenever or whereever only if they want to. It means that we can expect much greater improvements in medical services through the information exchanges. In this study the authors tried to ascertain the interchangeability comparing the obtained results of the CK tests between two general hospitals. Fortunately, the data got in the internal QC programs came to fall within the normal tolerances. The reference intervals for the CK test were different according to the chosen reagents and the results from the pooled sear were also shown differently each other. However. from the two hospitals. we could get glucose K factors, upon which the measurements were obtained and compared. Using K factors we measured the CKs, then we mulply the CK values by correction coefficients. We could found that the two results were showing good coincidence in the comparison. The main purpose of the standardization of enzyme assays is the creation of a new unified value can be expressed differently otherwise. Using the standardizad values we can exploit the data everywhere, reduce the medical costs from repeated or duplicated tests, save the foreign exchanges preventing the diversification of import connections.

The nationally-governed examinations for certification of allied health professions in Korea have been continued for thirty three years. During that time, there were a lot of managerial improvements in carrying out the examinations, for example, the looking-over the papers converted from manual method to computerized one. Nevertheless, the overall aspects of item management in the national examinations are still remained as obsolete style. In some developed countries they have already tried or adopted computerized system in making questions, executing item analysis, developing item banking, and in overall management of examinations, looking over papers for their national licensure examinations, and have established good reputations. Since the National Health Personnel Licensing Examination Board was established in 1998, now we can expect there would be a lots of improvements in the managerial systems and organizational structures associated with the national licensing examinations suggesting followings. 1. The contents and scope of the licensing examinations based on job analysis should be announced publicaly. 2. Items should be developed based on the scopes and contents of job characteristics. 3. All the developed items for the licensing examinations should be tested quantitatively prior to banking items. 4. All the parameters of the stored items should be fully estimated through item response theory. 5. All the efforts should be given in order to execute the examinations in individual residential areas on behalf of every examinee. 6. To the licensing examination system the Computerized Adaptive Testing system should be introduced in order to enhance the efficiencies. 7. Security enhancement on the stored items should be reminded in order to prevent leaking out the banking items. 8. Much more improvements should be made for the proper job evaluations. 9. Every efforts should be given to prevent cheatings encountable during the examinations. 10. Make the best of professional volunteers from the various fields in the execution of licensing examinations. 11. Consider a new system in that examinations can be executed twice or more In a year. 12. The current methods of presiding over the examinations should be replaced by a more reasonable one. 13. The results of the examinations should be announced as soon as possible In order not to prolong the examinees`` unemployment periods. 14. The National Health Personnel Licensing Examination Board should try to rationalize the management keeping step with the information-oriented society.

Since the Korean Association of Quality Assurance for Clinical Laboratory was established in 1976, the numbers of the participating hospitals nowadays were increased from 40 to 450 or more hospitals all over the country. In the early day the both internal and external quality control programs were started at the same time, however, the external QC programs prevailed over the internal ones putting the cart before the horse. The accuracy and the precision of the data are not satisfying in spite of the 20 years experiences of quality control programs. All the daily data should be reported after the validity is assured by the self-evaluation not by third party evaluation. It is regret that the CVs of enzymatic tests in external QC are exceeding 100/0 and there is no sign of diminishing CVs. One of the major reasons is that the types of anaytical instrurments and reagents are diverisified. Moreover, most of them are subject to the standards of the respective country of manufacturer. Accordingly, we can make a suggestion that the reagents and instruments should be instruments or supplied meeting the established requirements for Korean standardization.
