The purpose of this study was to analyze the relations among the three factors: 1) characteristics of family, 2) nutrient intake status and 3) academic achievements. The subjects in this study were 7,698 boys and girls attending primary, middle and high schools in South Korea. The questionnaire was made and distributed to the student to answer the questions about family background and food intake status. Food intake frequency method was used to examine nutrient intake status. Academic achievement results of last semester were taken from students school records. Followings are the results of the study:1. Most of the mean nutrient intakes were above the Korean recommended dietary allowances. However, calcium, iron, and vitamin A intakes were below the Korean recommended dietary allowances. Therefore, it is recommended to increase the intake of these nutrients in these students to meet the RDA.2. Total amounts of food intake were decreasing in higher grades and food intake of boys was higher than that of girls. 3. Educational period of parents and economic status of family had grades influences on student's academic achievement and nutritional status. The students with parents of higher education and higher economic status had better academic achievement and balanced nutritional status. 4. When students were divided into three groups with respect to the percentage of recommended nutrient intake, the group with nutrient intake of 75-125% of RDA achieved better academic achievement than other groups. In conclusion, educational length and economic status of parents and optimal intake of nutrients (75-125% of RDA)by students significantly affected academic achievements of the students.

The Ministry of Education have had us practice the performance test as a substitute proposal, however, all the more for the idealistic purport, our education front does not have such a sufficient condition as to practice the performance test for many classes and miscellaneous duties and over-populated class, and that practice has been enforced so abruptly without any drastic preparation and has caused much confusion from the beginning of that enforcement. Thus, these problematic concerns are remained as the tasks of the teachers to be solved by themselves in the front of education, and herein I came to do this research. The followings are the conclusions that I got as the results of the research (1) Performance test style should be applied in consideration of the students' achievement level and the gap of the teachers' recognition; descriptive test, portfolio assignment and formative test styles were proper for the students lacking basic study ability. (2) Descriptive test should have its beginning with the question items to which students can write the problem solving procedure logically rather than those to evaluate the creation ability and thinking ability: and putting down specifically the assessment standard could prevent students' confusion and scheme the impartiality of the assessment. (3) Portfolio assignment evaluation should be given with as interesting and suitable amounts as possible so that the students can do by themselves. (4) Utilizing the performance test table enabled easy management of documentary evidence. And it is needless to say that the success of the performance test should have preceding conditions like the teachers' understanding and their positive participation. Therefore, I'd like to give suggestions herein like the followings; (1) The performance test should not always be made into grades, and there is a need to develop the test gradually in the condition that the education surroundings permit by checking time, frequency, ratio and contents of the test while practicing the multiple choice writing test. (2) As long as the performance test has the aims of improving the studying and learning activities, any performance test only for the sake of making numerals with the thought that assessment is the disposal of the grades should be avoided, and the change of the lecturing styles and development of various assessing types and studying materials should be endeavored to confirm with the aims.

Background: Quantitative evaluation of renal cortical echogenicity (RCE) has been tried and developed in human and veterinary medicine. Objectives: The objective of this study was to propose a method for evaluating RCE quantitatively and intuitively, and to determine associations between ultrasonographic renal structural distinction and estimated glomerular filtration rate (eGFR) in canine chronic kidney disease (CKD). Methods: Data were collected on 63 dogs, including 27 with normal kidney function and 36 CKD patients. Symmetric dimethylarginine and creatinine concentrations were measured for calculating eGFR. RCE was evaluated as 3 grades on ultrasonography images according to the distinction between the renal cortex and outer medulla. The RCE grade of each kidney was measured. Results: There was a significant difference in eGFR between the group normal and CKD (p < 0.001). As mean of RCE grades (the mean values of each right and left kidney's RCE grade) increases, the proportion of group CKD among the patients in each grade increases (p < 0.001). Also, severity of RCE (classified as "high" if any right or left kidney evaluated as RCE grade 3, "low" otherwise) and eGFR is good indicator for predicting group CKD (p < 0.001). Conclusions: The degree of distinction between the renal cortex and the outer medulla is closely related to renal function including eGFR and the RCE grade defined in this study can be used as a method of objectively evaluating RCE.

본 연구는 초등학교 고학년(4, 5, 6) 학생들을 대상으로 성별에 따른 KSD 반응의 차이와 사회성측정에 의한 5가지 지위의 유형별로 KSD 반응이 다르게 나타날 것이라는 가설에 근거하여 진행된 연구였으며, 동시에 KSD 반응이 사회성측정의 지위 유형을 어느 정도 판별하는지를 확인하는 연구였다. A시에 소재한 4학년 5학급, 5학년 5학급, 6학년 10학급으로 총 20개의 학급에 대하여 안이환(2007)이 개발한 사회성측정과 Burns와 Kaufman(1970)의 KSD를 실시하였다. 피검자의 수는 총 366명이었으며 엄밀한 형태의 층화군집표본 추출법은 아니었다. 3개의 가설을 검증하기 위하여 차례대로 독립표본 t 검증, 일원변량분석, 판별분석법이 사용되었다. 그 결과, 성별에 따른 KSD 반응의 3요인 가운데 인물상의 행위, 인물상의 특징에서 통계적으로 유의미한 차이가 있는 것으로 나타났지만 역동성 요인에서는 유의미한 차이가 나타나지 않았다. 또한, 일원변량분석의 결과 여학생의 KSD 반응 가운데 인물상의 특징 및 역동성 요인에서는 통계적으로 유의미한 차이가 나타났지만 인물상의 행위 요인에서는 유의미한 차이가 나타나지 않았다. 따라서 KSD 반응 가운데 인물상의 특징이 남녀에 대한 구분 및 사회성측정의 지위 유형과 깊이 관련되어 있음을 알 수 있었다. 본 연구의 결과로 볼 때, 田中志帆(전중지범)(2009)이 제안한 KSD 채점체계 영역에 대한 검토의 필요성 이 제기되었다. 마지막으로, KSD 반응이 사회성측정을 잘 판별하지 못하는 것으로 나타났지만 사회성측정을 보완하는 도구로서의 투사적 그림검사에 대한 새로운 접근법이 필요하였다.
