This study aims to investigate the statistical literacy of pre-service mathematics teachers and to discuss the impact of statistical literacy in lesson plan. For the purpose of this study, we analyzed 13 pre-service mathematics teachers' statistical literacy tests and lesson plans. The results of this analysis are as follows: First, pre-service mathematics teachers did not have a high level of statistical literacy, and it was also observed that there was a big level difference between them. Second, pre-service mathematics teachers' lesson plans showed significant difference in the level of the target grade, the characteristics of the target student, and the contents. Based on this study, we seek to find implications for how it is appropriate to educate teachers in charge of statistical education.

This paper examines the current state of operation of the historical museum in Gumi, Oki Island, which opened on June 1, 2016, along with archives of Shimane Prefecture related to Dokdo. The Gumi Jukdo Historical Museum has a map of Dokdo, which explains mining rights, which include the mining of phosphorus. In addition, Japan insists that it can confirm that the lighthouse, which was allegedly installed by the Korean side in 1954, is not illuminating. From 1905 to 1965, the fishermen of the Gumi district licensed the fishermen of Dokdo Island, except for the post-war period, during which Dokdo was allowed to fish on Dokdo Island. Since 1953, Shimane Prefecture has issued licenses to the OkinoSima Fisheries Cooperative Federation for the Dokdo Co-Fishery and the private Yahata Isaburo(八幡伊三郎). It records the date, the weather, the catch, and the conversion of the fishery in Dokdo (over the period 1936-1938). The Japanese government, through the colonial occupation of Korea at that time, looted everything using all possible means and methods, if there was any benefit to Japan. In this paper, the charts of Japan"s individual capture of Dokdo evidently indicate that Dokdo belongs to Korea.

2017년 8월 전주는 30도를 웃도는 무더운 날씨가 계속되었다. 전주에서 태양 빛띠(solar spectrum)을 측정하여 플랑크 흑체복사 법칙 그리고 대기 밖에서 측정된 태양의 빛띠와 비교하였다. 전주에서 측정된 태양의 빛띠로부터 태양의 온도는 약 5800 K라는 것을 확인할 수 있었으며, 전주를 덮고 있는 대기 중에는 수분뿐만 아니라 많은 미세먼지로 인하여 태양 빛이 많이 흡수 및 산란된다는 것을 알 수 있었다. 또한 하루 중 오전 11시부터 오후 2시 사이에 태양 빛의 세기가 가장 강하며, 500 nm보다 긴 파장의 빛이 오후에 더 많이 지표에 도달한다는 것을 밝혔다. 이 결과는 오후의 온도가 오전보다 높은 것이 태양에 의하여 가열된 지표의 영향뿐만 아니라 오후에 더 많이 들어오는 긴파장 빛도 영향을 미친다는 것을 의미하는 것이다. It was a very hot summer in August 2017 over 30oC. Solar spectra were measured and compared with Planck’s law for Blackbody radiation and a solar spectrum taken at top of the atmosphere. Measured solar spectra confirmed that the Sun temperature is approximately 5800 K and that the Sun light is absorbed and scattered by moisture and also particulate matter in air. The strongest intensity of Sun was observed from 11 AM to 2PM. More Sun lights with wavelengths above 500 nm come to the Earth surface around 2PM then 9AM. This results in increase of temperature on the Earth surface during afternoon, although higher temperature at afternoon than in the morning is mainly influenced by heating of Sun during the morning.

The purpose of this study was to investigate the effect of body composition and physical fitness after 8weeks combined exercise of aerobic exercise and anaerobic exercise training program. subjects were consisted of 30 middle-aged women (control group 15, exercise group 15). The combined exercise program was composed of stretching, aerobic exercise, anaerobic exercise, performed 60~70min, 3times per week for 8weeks. The results of this study were as follows: the weight, %fat, WHR of the exercise group before test were, higher than those of the same group after exercise. Also, the muscular strength, muscular endurance, flexibility, agility, power, cardiovascular endurance of the exercise group before test were higher than those of the same group after exercise. It was concluded that the 8weeks of combined training of aerobic exercise and anaerobic exercise would have positive effect on body composition, physical fitness.
