본 연구는 전산유체역학 모델을 이용하여 기상청에서 운용하는 종관기상관측소(automated synoptic observing system, ASOS) 10개 지점을 대상으로 ASOS 주변 지형과 건물이 기온과 바람(풍속, 풍향) 관측 환경에 미치는 영향을 분석하였다. ASOS에서 최근 10년간 8월의 관측 자료를 기반으로 전산유체역학(computational fluid dynamics, CFD) 모델의 초기·경계 자료를 구축하였다. 실제 토지 피복을 고려한 경우와 모든 피복을 초지로 가정한 경우에 대해, 관측 고도에서 초기 기온 대비 기온 변화율을 비교함으로써 기온 관측 환경을 분석하였다. 기온 관측 환경은 관측 지점 주위의 토지 피복에 의한 영향을 많이 받았다. ASOS 주변에 지표면 온도가 높은 건물과 도로가 밀집한 경우에 기온 변화율이 크게 나타났다. 반면, 모든 토지 피복을 초지로 가정한 경우에는 초기 기온 대비 기온 변화율이 작았다. 실제 토지 피복을 고려하여 관측 고도의 유입류 대비 풍속 변화율과 풍향 변화를 비교함으로써 풍속과 풍향 관측 환경을 분석하였다. 풍속과 풍향은 ASOS 주변에 관측 고도보다 높거나 비슷한 높이의 지형과 건물 영향을 크게 받았으며, 원거리에 위치한 장애물에 의한 영향도 나타났다. 본 연구 결과는 종관기상관측소의 이전과 신설 단계에서 관측 환경 평가에 활용될 것이다.

This study analyzed the quality of mathematics classes with observations using the instrument, MQI(Mathematical Quality of Instruction). Class recordings and interviews were conducted on 2 pre-service teachers and 4 in-service teachers. This study recorded and analyzed 3 or 4 classes for each mathematics teacher by using revised MQI. There were a total of 8 raters: 2 or 3 raters analyzed each class. MQI has four dimensions: Richness of the Mathematics, Working with Students and Mathematic, Errors and Imprecision, Student Participation in Meaning-Making and Reasoning. In the dimension of 'Richness of Mathematics', all teachers had good scores of 'explanations of teacher' but had lower scores of 'linking and connections', 'multiple procedures or solution methods' and 'developing mathematical generalizations.' In the dimension of 'Working with Students and Mathematics', two in-service teachers who have worked and having more experience had higher scores than others. In the dimension of 'Errors and Imprecision', all teachers had high scores. In the dimension of 'Student Participation in Meaning-Making and Reasoning', two pre-service teachers had contrast and also two in-service teachers who hadn't worked not long had contrast. Implications were deducted from finding to improving quality of mathematics classes.

In this study, 45 pre-service mathematics teachers were surveyed about how the perception of knowledge through teaching practicum have changed and how the knowledge learned in college and teaching practicum helped to format teachers' knowledge and analyzed survey's result. Pre-service mathematics teachers felt the knowledge for understanding students were needed the most and considered the experiences from teaching practicum were more useful than the knowledge learned from college classes. However, they had low appreciations on connecting knowledge on learned contents with real-life or other subjects and on necessity of knowledge of using various learning tools or mathematical materials in class. Also, they have answered the knowledges from college classes and teaching practicum were useless in those areas. Especially, they pointed out that guidance teachers during teaching practicum were insufficient in instructing. Therefore, we suggest the following two to improve the teaching ability of pre-service mathematics teachers through teaching practicum. First, college and secondary school cooperating programs such as class-observation and student-mentor system connected with local society should be developed. Second, the special re-training program for guidance teachers of teaching practicum is needed.

In Korean historical documents, there are a great number of the records for various astronomical events. In particular, historical documents of the Joseon dynasty also have the records containing observational data by an astronomical instrument. However, a quantitative analysis for the accuracy of observational values have never been studied, although there are some studies on the truth of the records themselves. Hence, we investigated observation errors during the period of the Joseon dynasty from the records of Joseon-Wang-Jo-Sil-Lok (the Annals of the Joseon Dynasty) and Seung-Jeong-Won-Il-Gi (Daily Records of the Royal Secretariat). We used the records of the Mars, supernova 1604, and Halley's Comet, and found that observational values before the Hideyoshi invasions in 1592 are relatively more accurate than those after then. However, because the number of cases used in this study is small, we think that more studies are needed to confirm our results. Nonetheless, we reckon our work will be of service to understand astronomical records of the Joseon dynasty.

Purpose - This paper studies whether CISG can be a suitable governing law for pure service contracts. When CISG was first drafted, there was little disagreement on the fact that contracts for the sale of goods and those for the provision of services were two different types of contract. Based on this understanding, CISG explicitly provides that the Convention will apply to contracts where the preponderant part of the contractual obligation is on the sale of goods, not services. However, as more sales transactions have come to include more elements of services, mainly due to the advancement of the IoT industry, the distinction between goods and services became more blurred. Based on the observation of recent changes, some scholars even argue that such a change supports the applicability and suitability of CISG to even pure service contracts. The purpose of this paper is to critically analyze and evaluate their argument. Design/methodology - This paper focuses on two separate but related issues: CISG's 'applicability' and 'suitability' to service contracts. For the first issue, this paper will examine the rules of interpretation of international treaties under the Vienna Convention on the Law of Treaties of 1969, and will apply its rules to find the proper answer. For the second issue, this paper will perform logical and empirical analyses on the reasoning employed by scholars claiming the suitability of CISG to service contracts. Findings - This paper concludes that CISG does not, and should not, apply to pure service contracts. The argument that CISG applies to pure service contracts directly contravenes Article 3(2) of the Convention, which expressly states that it does not apply to a contract wherein the preponderant part of its obligation is about services rather than sales. Similarly, CISG is not a suitable governing law for pure service contracts because it aims provide rules specifically tailored to the needs of transactions of sales of goods, not services. Servitization of sales of goods transaction does not change this conclusion. Originality/value - This paper presents different views from those offered by some eminent scholars on the issue of applicability and suitability of CISG to service contracts. By doing so, it is hoped that the confusion caused in discussions so far are clarified. Hopefully, this paper can also provide practical guidance to practitioners engaged in the fields of international sales, services, and IoT industries.
