We investigate the process of western mathematics into Chosun and its influences. Its initial and middle stages are examined by Choi Suk Jung(崔錫鼎, $1645\sim1715$)'s Gu Su Ryak(九數略), Hong Jung Ha(洪正夏, $1684\sim?$)'s Gu Il Jib(九一集) and Hwang Yun Suk(黃胤錫, $1719\sim1791$)'s I Su Shin Pyun(理藪新編), Hong Dae Yong(洪大容, $1731\sim1781$)'s Ju Hae Su Yong(籌解需用), respectively. Western mathematics was transmitted for the study of the Shi xian li(時憲曆) when it was introduced in Chosun. We also analyze Su Ri Jung On Bo Hae(數理精蘊補解, 1730?) whose author studied $Sh\grave{u}\;l\breve{i}\;j\bar{i}ng\;y\grave{u}n$ most thoroughly, in particular for astronomy, and finally Lee Sang Hyuk(李尙爀, $1810\sim?$), Nam Byung Gil(南秉吉, $1820\sim1869$) who studied together structurally western mathematics.

The purposes of this study are clarifying the characteristics of women's hair style in the late Joseon Dynasty by inquiring into that hair style and, by extension, having a new understanding of the aesthetic consciousness of women in those times. The typical hair style of married Joseon women was Ungeonmeori and Jjokmeori, with Ungeonmeori being much more popular. Regardless of socioeconomic status, women used a big Gache as long as conditions permitted. Meanwhile, some women who led the trend or followed the national policy did Jjokmeori and wore Jokdoori. The Joseon Dynasty had a strict clothing system. However, giseangs were free from this restriction and they were free at attire. Therefore, they led the fashion trend. Both noble and common women followed the trend, imitating giseangs' attire. Women's hair style was used as a tool to express one's personality in the late Joseon Dynasty when the hierarchy was already weakened. In fact, it seems that women in those times cared more about hair style trend than clothing trend. This means that those women already had such a high quality of aesthetic consciousness that they showed their hair which is the closest to the face to advantage.

This study analyzed the perception of prospective elementary school teachers in relation to using the history of Korean mathematics. The results of this study showed that the pre-service teachers realized using the history of Korean mathematics more importantly than the history of mathematics. They thought that the contents of the history of Korean mathematics should be increased in mathematics education and pre-service teacher education. The participation experience in teacher education about the history of Korean mathematics had a positive effect on the perception of pre-service teachers. Finally, this paper asserted that teacher education is the key to the teacher perception on and using of the history of Korean mathematics.

The Goon-rearrangement in 1914 caused a significant change in the Goon office buildings' construction in the Japanese colonial period. The aim of this study was to discover the administrative procedure for the construction of them around the Goon-rearrangement and also in the 1910s generally, the Japanese government-general's policy for the construction and the buildings' condition. This study analyzes the official documents for the Goon-rearrangement between the Japanese government-general of Korea and the To, the digital images of the buildings kept in the National Archive of Korea and the newspapers published in 1910s. This paper examines what the effect the construction had under the stance of the Japanese government-general of Korea, which was very passive regarding the construction of new buildings.

In quay processes in shipyards, it is difficult to manage workers and to maintain secure working environments because at least 1,000 people can occupy the quay at the same time. In this study, a system was designed to monitor the environment and processes of quay operation. In order to lower initial investments and the costs of maintenance and operation, the entire system consists of six connected components. Considering the communication environment of the shipyard site, Wi-Fi and the LoRa communication protocol were selected for the system. The feasibility of the communication protocols was verified by data transmission tests in the field. The designed system can provide real-time information about employees working in the quay area, the safety status of moored ships on the quay, and step-by-step alarms in dangerous situations based on the detected information. The system is expected to prevent or greatly reduce safety hazards.

This study analyzed the recognition types of the economic burden for cancer treatment and the characteristics of each recognition type by employing Q methodology. For this study, we determined the final 45 Q statements by conducting literature surveys, internet searches and in-depth interviews. The P samples are 35 people of cancer patients, their family members, and experts. The Q statements were classified according to the forced normal distribution method and the collected data was analyzed using the PC QUANL program. For the analysis results, we extracted four recognition types on the economic burden of cancer treatment, and we named them 'uncertain anxiety', 'acceptance by family burden', 'object to challenge with active response' and 'insurance preparation', depending on their characteristics. The results of this study can be used as a basis for preparing the clinical intervention plan and the policies for cancer patients and the families involved in the fields of medicine, nursing and social welfare.

Hong Jung Ha(洪正夏, 1684~?) is the greatest mathematician in Chosun dynasty and wrote a mathematics book Gu Il Jib(九一集) which excels in the area of theory of equations including Gou Gu Shu. The purpose of this paper is to find his influence on the history of Chosun mathematics. He belongs to ChungIn(中人) class and works only in HoJo(戶曹) and hence his contact to other mathematicians is limited. Investigating his colleagues and kinship relations including the affinity and consanguinity, we conclude that he gave a great influence to those people and find that three great ChungIn mathematicans Gyung Sun Jing(慶善徵, 1684~?), Hong Jung Ha and Lee Sang Hyuk(李尙爀, 1810~?) are all related through marriage.

Comparative analysis of the nursing students' empathy ability, positive psychological capital, and interpersonal competence of Korea and Korean-Chinese in China was conducted. Data were collected from160 survey questionnaires from Nov.1 to Dec 30, 2019, from Korea and China. The data use frequency and percentage, mean, independent t-test, and Pearson's correlation coefficient were analyzed. The results showed that Korean nursing students' empathy, positive psychological capital, and interpersonal competence scores were higher than Korean-Chinese nursing students in China. The empathy ability of Korean nursing students had no significant correlation with positive psychological capital and interpersonal competence. The empathy ability of the nursing students of Korean-Chinese had a significant positive correlation with the positive psychological capital and interpersonal competence. The higher the empathy ability, the higher the positive psychological capital and higher the interpersonal competence. Several intervention programs will be needed to increase the empathy ability, positive psychological capital, and interpersonal relationship of Korean-Chinese nursing students.

최초 19세기말 빙해역으로 둘러싸인 북유럽의 핀랜드 등지에서 쇄빙선을 건조하는 경험으로부터 출발하여 이제는 북극해 연안의 해저자원 개발과 더불어 극한지에 관한 종합적인 학문의 형태로 변모하고 있다. 이미 선진제국에서는 양극지방의 환경자료와 함께 상당한 양의 극한지 실험결 과를 축척하고 있다. 앞으로 개발의 손길을 기다리는 세계 도처의 빙해지역에서 막대한 양의 해저석유자원이 얻어질 것이라고 확신한다. 우선 시베리아 천연자원의 개발사업 같은 국내의 극지관련 기술수요를 창출하는 것이 급선무이지만 그와 함께 극지 자원 개발에 필요한 구조물의 제작이나 설치, 운용 등 외국으로부터의 기술수요에도 능동적으로 대처할 수 있는 준비가 필 요하다. 이를 위해서는 먼저 우리 나라의 제반 경제여건에 맞는 기술부분에 계획적이고도 집중 적으로 투자하는 것만이 효율적인 해결책일 것이다. 이와 함께 선진국의 앞선 극지관련 기술을 습득하기 위한 인적교류를 확대하고 국내에서도 극지공학에 관련된 기술인력을 계속 확보하는 노력이 절실히 요구된다. 극지개발은 이론적 접근과 함께 실험에 의한 신뢰성 있는 자료를 축 적해야 한다. 국내의 조선해양산업의 경험과 기술수준으로 판단 할 때 극지관련 공학기술을 가장 빨리 정립할 수 있는 분야는 극지용 해양구조물과 빙해항행선박의 설계 및 건조기술이라 볼 수 있다.

Iksan(翼算) written by Lee Sang Hyuk(李相赫, 1810∼\ulcorner) is unique among mathematical books published in Chosun Dynasty since it is the only book which accomplishes the conceptualization of theory of equations if not that of mathematics itself. We investigate its process by his other publications and mathematical interaction with Nam Byung Gil(南秉吉, 1820∼1869).
