The concepts of sample and sampling are central to the statistical thinking and foundations of the statistical literacy, so we need to be emphasized their importance in the statistics education. However, many researches which dealt with samples only analyze textbooks or students' responses. In this study, the concept of sample is addressed by a historical consideration which is one aspect of the didactical analysis. Moreover, developing concept of sample is analyzed from the preceding studies about the statistical literacy, considering the sample representativeness and the sampling variability. The results say that the historical process of developing the concept of sample can be divided into three step: understanding the sample representativeness; appearing the sample variance; recognizing the sampling variability. Above all, it is important to aware and control the sampling variability, but many related researches might not consider sample variability. Therefore, it implies that the awareness and control of sampling variability are needed to reflect to the teaching-learing of sample for developing the students' statistical literacy.

The purpose of this study is to analyze common inquiry tasks of middle school history textbooks and find out it's implications on teacher librarians' educational information services. There are 84 common inquiry tasks according to examinations of inquiry tasks related to world history in 18 kinds of middle school history textbooks. Results of the analysis show that almost all of common inquiry tasks of world history make middle school students who should resolve them research the pictures and reading materials included in the textbooks individually and verbalize under the information literacy process. Compared with information literacy process of the "Library and Information Skills" for middle schools, the First step of task definition and figuring out information needs and the Third step of representation of information are being implemented. For this reason, teacher librarian could reduce history studies teachers' burden of running the class and promote students' inquiry activities by teaching skills of information analysis and interpretation, synthesis and organization and evaluation of their information literacy process and results.

The total number of railroad stations managed in Korea is 322 (including general and wide-area railways), and a considerable number of stations are aging. In terms of the size of the existing railway station and the number of entrances, it has not been possible to secure adequate service capacity, and the demand for station improvement is increasing due to changes in surrounding conditions such as urban development. In the past, railroad stations were focused on the simple function of a connection passage in terms of maintenance or management, but in recent years, railroad stations are also changing to an atmosphere that they should be reborn as a user-centered comfortable, convenient, and safe service provision space. In this study, a case study related to the improvement of the old railway station was conducted to derive an improvement plan that meets the improvement standard of the old station, and the service level evaluation standard was developed. By introducing the concept of service level (LOS) in the development model, station congestion, station movement convenience, and station safety were selected as evaluation indicators. In addition, this development model applied an analytical stratification technique to divide various evaluation elements of each indicator into major and detailed elements and derive the relative importance of the elements by class. Priority for improvement was derived using the ratio of the number of E and F on the LOS for each facility. Based on this study, it is expected to be helpful in using it as an evaluation criterion for improving objective and equitable railway station.

This study focuses on the analyzing historical and cultural resources formed during the Goryeo, Chosun, and Anti-Japanese Movement periods after the Silla period with the aim of finding ways to utilize its cultural contents. The viewpoint of analysis was made from the perspective of exchange, naturalization, and faith, and the following conclusions were obtained from the analysis. First of all, from the exchange perspective, the activities of Choi Chi-won, Seogyu, and Song Young-gu contributed to the formation of regional historical and cultural contents, such as leaving a lot of ruins or geographic stories in the area and a heritage of good human exchange. From the point of view of naturalization, Du Kyung-ryeong, Cheon Man-ri, and Jeong Yul-seong contributed to the history and culture of the story and the formation of heritage by doing such as contributing activities to the war, anti-Japanese movement for the nation, and the formation of the nation. The most representative from a religious point of view is the Guan Yu faith, which has become a faith believed by the authorities and civilian as a brave longevity and a symbol of the victory of war. The related symbols, paintings, etc. also are objects of worship and have become valuable local Chinese cultural resources as artistic values. Therefore, from a cultural point of view, there is a need to further develop and utilize these China-related historical and cultural resources as good cultural contents by elaborating their stories and local festivals, book culture branding, international music festivals, and exploring various cultures such as Chinese tour courses.

The purposes of the study were two-folded: to identify visitors' motivations for the history-based dark tourism and to test empirically the relationships among visitors' motivations, authenticity, emotion, satisfaction and attitude change. The online survey was conducted, from August 3rd to 20th of 2020, on visitors over 15 years old with previous experience with dark tourism within last three years. 347 individuals responded to the online survey. The study results were as follows: first, among four dark tourism visiting motivation including, motivation to research, historicalness, deviation, and self-examination, first two variables motivation to research and historicalness showed positive effect on authenticity and emotion. Second, the study found that visitors' satisfaction influenced positively towards attitude change. Finally, authenticity and emotion positively influenced attitude change. This study empirically suggests a change in attitude toward history due to the dark tour. Since historicality has been shown to have a significant influence on the attitude of history through authenticity and emotion, it is necessary to strengthen story-based experience programs at historical sites.

일본은 한국과 역사적 문화적으로 많은 공통적 유사성을 띠고 있다. 그리고 한국과 일본은 경제발전의 여건이 유사하면서 사회보장제도의 차이가 있다. 따라서 세계 경제대국인 일본의 사회보장제도의 연구가 필요하다. 그 이유는 우리의 실정에 부합하는 일본 사회보장제도의 도입과 보완 그리고 일본 사회보장제도의 확충과 발전을 도모함에 있어 필요하다는 것이다. 따라서 본 연구는 일본의 사회보장제도를 역사적 관점에서 이론적 연구방법론에 입각하여 일본의 사회보장제도의 구조를 분석하며 그 성립과 발전의 과정을 경제적 사회적인 발전의 배경하에 개관하고 그 현황을 분석하고 검토하는데 그 목적이 있다. 나아가 오늘날 일본이 당면한 사회보장제도의 문제를 명확하게 인식하고 그 발전을 전망해 보는데 있다.

본 연구는 서양의 과학적 합리적 이성주의에 대한 단절된 동양문화의 상징적 사유체계에 내재된 상상적 환경을 복원하는 것을 목적으로 하였다. 상상적 환경을 복원하기 위해 한국 중국 일본의 고대도시인 서울, 북경(北京), 교토(京都) 등을 사례대상지로 선정하였다. 이들 사례도시의 역사 문화경관을 분석하여 상상적 환경요소를 도출하고자 해석학과 현상학적 접근방법을 활용하였다. 동북아시아 삼국(한 중 일)의 역사문화경관 비교와 재해석을 통해 그 속에서 내재된 상상적 환경을 도출한 결과, 각 도시에 내재된 장소의 정신과 자연환경요소가 인문환경요소로 반영되어 구조화되었으며, 개별요소들이 결합하여 조직화되었고, 점진적으로 장소(場所)의 혼(魂)은 더욱 성화(聖化)되었다. 본 연구는 인간생활의 실존적(實存的) 장(場)인 도시공간을 상상적 환경이라는 새로운 개념으로 비교분석한 최초의 시도로서 의의를 가진다. 그러나 동북아시아 삼국의 역사문화경관에 내재된 상상적 환경의 보편성을 확인한 것은 의미가 있으나, 각 도시별 세부적인 요소에 이르기까지 특수성을 밝히는 데는 한계가 있었다.
