Theoretical bases for the necessity of land’s economic estimation have been disclosed. Peculiarities of developing the ways of agricultural land estimation in Ukraine have been researched as well as the methods of land estimation in Ukraine which will allow the precise estimation of national wealth, taking into account its ecological state, have been suggested. Розкрито теоретичні основи необхідності економічної оцінки земель. Досліджено особливості розвитку способів оцінки земельних угідь сільськогосподарського призначення і запропоновано спосіб оцінки земель України, який дозволить точно визначити вартість національного багатства країни з урахуванням їх екологічного стану.

Simultaneous measurement of plasma, RBC, and plasma lithium concentrations took place with 17 inpatients chronically treated with lithium, at various times after the last lithium dose. RBC lithium levels were significantly higher than CSF lithium levels. Specimens drawn 10 or more hours after the last dose showed higher RBC and CSF lithium and lower plasma lithium than specimens drawn 4 or less hours after the last lithium dose. None of the lithium measurements differentiated manic-depressives from schizophrenics or schizoaffectives. Plasma, RBC, and CSF lithium all intercorrelated highly and equally.

Measurement involves actual measuring or estimating to generate a quantitative understanding of a phenomenon. Estimation in particular refers to the process of obtaining measurements without a measuring tool. This paper aims to investigate didactical implications for estimation by analyzing the estimation activities of textbooks. To this end, we focused on estimation activities in elementary school mathematics textbooks from the seventh to the 2015 revised national curriculum, analyzing them based on activity quantity, estimation type, and estimation strategy. As regards length, the estimation activities were presented appropriately in terms of quantity, type, and strategy. However, other attributes were insufficient in quantity while some activities showed biases and limitations with few estimation strategies to use in a variety of contexts. Based on these results, we propose the inclusion of achievement standards for time, area, and volume and argue that the textbook should address various types of and strategies for estimation activities.

Stable dodecaphenylporphyrin–lithium complexes are formed at room temperature and the lithium ions of these complexes are replaced easily by other metal ions or organic cations; these lithium complexes can be used as the reagents in the syntheses of various complexes.

Evidence is presented indicating that 2,5-dimethoxythiophen is metallated in the β-position by butyl-lithium to give 2,5-dimethoxy-3-thienyl-lithium, which subsequently undergoes ring-opening. By the use of 2 equiv. of butyl-lithium followed by dimethyl sulphate, it was possible to isolate 1-methylthio-octa-1,3-diyne as the main product.

본 연구의 목적은 현 2009개정 교육과정 초등학교 2학년 수학 교과에 미비하게 다루어져있는 어림 측정 영역을 강화하여 학생들의 길이 어림에 대한 이해와 어림 능력의 변화를 살펴보는 것이다. 이에 본 연구에서는 어림 측정 내용을 세 가지 어림 전략을 투입하여 어림을 강화한 수업으로 재구성하여 학생들에게 수업한 후 학생들의 길이 어림에 대한 이해가 길이 어림 능력에 미치는 영향에 대하여 살펴보았다. 연구 결과, 학생들은 어림의 의미를 정확히 이해하고 상황에 따라 적절한 어림 전략을 활용하여 오차를 줄여나가는 모습을 보였다. 또한 어림 전략을 활용하여 문제 해결 과정을 논리적으로 설명하는 능력도 향상되었다. The purpose of this study is the reorganization of the curriculum on the measurement, a part of the second grade math curriculum, for the improvement of the estimation capability in the elementary school students. Research questions were as follows: (1) how are the estimation capabilities of the students who have taken lessons on the diversified estimation strategies? and (2) how are the mathematical writing capabilities of the students who have taken lessons on the diversified estimation strategies? The study using reconstructed lessons was conducted on 18 second grade students in an elementary school located in Seoul. Results show that the students' estimation capabilities and have improved. They started to use 'about' when writing estimation results, different from writing the accurate measurements. Measurement errors were gradually reduced, ending up with a student who could accurately estimate exactly 1m. In addition, their estimation capabilities in using appropriate estimation strategy and writing skills describing the estimation strategy have improved.
