In the 1920s, the period of cultural governance ruled by Japan, the diverse media were founded and various events were conducted to boost circulation. Under the Japanese colonial period in 1920s, a number of media - newspapers and magazines - were published and often they carried out entertaining events in order to obtain more subscribers. A hobby magazine, Samchunri, for instace, set up a media event to selecting Korea's eight beautiful scenary (Bandopalgyong) for the first edition in 1929. The paper aims to analyse and understand the perception of landscape in 1929 through the media event carried out by Samchunri. In particular, the selection was made by well-known writers within Japanese colonial period 1910 - 1945). The selection process and views from the writers on landscape were analysed; firstly, the selection of Bandopalgyong was carried out by questionnaires to writers in 1929 where Korea is under Japanese colonial rules. The conditions of the selection were unknown; however, the purpose was enlightening the people specially the youngs and introduction of beautiful places in Korea. As a result, views and opinions on Bandopalgyong by the writers were progressed. Secondly, within the Bandopalgyong, the natural landscape areas include Gumgansan(金剛山), Daedonggang(大洞江), Buyeo(扶餘), Gyongju(慶州), Myongsasipri (明沙十里), Haundae(海雲臺), Baekdusan(白頭山), and Choksukru(矗石樓). Those chosen places were not cohesive nor did not have any consistant reasons to be chosen in terms of size and location; however, some writers claimed that there were other places to match the chosen ones and therefore, the selection process was highly dependent on access (i.e. transport). Thirdly, the travelogue on Baekdusan and Nackwhaam(洛花岩) illustrated interesting views on landscape in particular. Baekdusan landscape were described in overlaping with long history and national soul. In the Nackwhaam travelogue, it described 'Buyeo (夫餘) was an ancient capital of Backjae Dynasty and empty place' as well as denying Chosun Dynasty. It was assumed that the two places weren't visited but rewritten with existing literatures. Fourthly, edited by Kim Dong Whan, a travelogue style book, 'Bandosanha' was published in 1941. It did repeat the selection of Bandopalgyong, but this time, it was classified the eight beautiful landscape into two categories; historic/cultural places and natural landscape. This paper was able to analyse and understand the perception of landscape in 1929 through the travelogue of Samchunri. It is an empirical study on the process and perception on Korea landscape under Japanese colonical period by views of the selected writers.

Regional unconformities have been used as boundaries of major stratigraphic units in Korea. The term "synthem" has already been propsed for formal unconformity-bounded stratigraphic units of maximum magnitude (ISSC, 1974). The unconformity-based classification of the strata in the cratonic area in Korea comprises in ascending order the Kyerim, $Sangw{\check{o}}n$, $Jos{\check{o}}n$, $Py{\check{o}}ngan$, Daedong, and $Ky{\check{o}}ngsang$ Synthems, and the Cenozoic Erathem. The unconformites separating them from each other are either orogenic or epeirogenic (and vertical tectonic). The sub-$Sangw{\check{o}}n$ unconformity is a non-conformity above the basement complex in Korea. The unconformities between the $Sangw{\check{o}}n$, $Jos{\check{o}}n$, and $Py{\check{o}}ngan$ Synthems are disconformities denoting late Precambrian and Paleozoic crustal quiescence in Korea. The unconformities between the $Py{\check{o}}ngan$, Daedong, and $Ky{\check{o}}ngsang$ Synthems are angular unconformities representing Mesozoic orogenies. The bounding unconformities of the $Ky{\check{o}}ngsang$ Synthem involve non-conformable parts overlying the Jurassic and late Cretaceous granitic rocks.

The vocabulary of modern grand hotels' interior designs reflects western design patterns, showing its nostalgia for modern architecture. And it also contains the trace of past designs implanted by others then, expressing the hardships of Korean history. Like this, the past architectural style distorted under the Japanese imperialistic rule has continued to exist until now without any significant changes, because there has been little effort to figure out the history of modern interior designs. And also there has been the lack of data and aesthetic descriptions about the modern interior designs that contain the historical nature of society. Therefore, this study will review the interior design of modern buildings, which trace back to the fawning of the Korean Interior Design. And it aims to understand the hotel interior's expressive characteristics and historical meanings by paying a particular attention to its lost parts. And it also alms to have a significant meaning in taking the first step toward a clue of the history of Korean modern interiors by systematically putting in order the ever-disappearing materials of modern hotel interiors.

In this study, Sn-3.5Ag-15.0Fe composite solder was manufactured and applied to TLP bonding to change the entire joint into a Sn-Fe IMC(intermetallic compound), thereby applying it as a high-temperature solder. The FeSn₂ IMC formed during the bonding process has a high melting point of 513℃, so it can be stably applied to power modules for power semiconductors where the temperature rises up to 280℃ during use. As a result of applying ENIG surface treatment to both the chip and substrate, a multi-layer IMC structure of Ni₃Sn₄/FeSn₂/Ni₃Sn₄ was formed at the joint. During the shear test, the fracture path showed that cracks developed at the Ni₃Sn₄/FeSn₂ interface and then propagated into FeSn₂. After 2hours of the TLP joining process, a shear strength of over 30 MPa was obtained, and in particular, there was no decrease in strength at all even in a shear test at 200℃. The results of this study can be expected to lead to materials and processes that can be applied to power modules for electric vehicles, which are being actively researched recently.

This paper aims to investigate the value and resilience of Nogeoldae which was written at the end of Koryo dynasty and has been used as the most important foreign language education materials throughout the 500 years of Chosun dynasty. To this end, 106 volumes of dialogues, 12 of meeting, 17 of lodging, 21 of Daedo bound, 34 of Daedo lives and 11 of return in Nogeoldae are analyzed by an average length of the sentences, an average length of words, type-token ratio, number of words before main verbs and number of words before nouns to identify the progressive degree of the complexity. The result of the analysis shows that Nogeoldae presents a desired progressive complexity found in modern foreign language textbooks.

본 논문의 연구목적은, 우리나라 감자재배지역의 분포 특징과 그 중심지를 밝혀 보는데 있다. 이와 같은 목적을 위하여 감자가 외국에서 우리나라에 전파해온 경로와 한국 내에서 의 전파경로를 알아보고, 7개 지역의 감자재배지역의 특징, 우리나라 감자재배의 생산량, 재배면적, 재배농가, 각 시기별 감자 재배지의 중심지와 남한의 감자재배 중심지를 구하였다. 이와 같은 연구내용은 주어진 자연환경에 인간이 어떻게 적응해가면서 살아가는지를 공부하는 지리학의 전통적인 개념인 자연과 인간과의 관계를 이해하는데 도움을 줄 수 있을 뿐만 아니라, 초 중등학교 및 대학에서 공부하는 한국지리 교육과정의 학습자료로서 유용하게 쓰일 수 있을 것으로 기대한다. 연구방법은 문헌연구과 1970년부터 1995년까지의 전국의 시.군별 감자재배지역의 입지계수를 구하여 연구하였다. 그 결과를 요약하면 다음과 같다. 1. 감자가 한국에 처음으로 재배된 것은 1824년(조선조 순조24년) 인데, 전파과정을 살펴보면, 안데스산지의 페루(1500년대) $\longrightarrow$ 에스파냐(1532년) $\longrightarrow$ 중국(1650년) $\longrightarrow$ 한국(1824년)순으로 전파되어온 북방전래설과 영국의 감자가 1832년 충청도의 서산으로, 일본 감자가 1920년에 수원으로 전파되었다는 남방전래설이 있다 2. 감자는 한국 전 지역에서 재배되는 중요 농작물이다 그러나 우리나라의 지형이 남북으로 깊게 뻗은 반도국이므로 위도와 지형 차이에 따라 기온과 고도가 다르게 나타나는데, 이러한 자연적인 요인의 영향이 가장 큰 요인이 되어 고랭지 여름재배지역.중산간 봄재배지역.중부평야 봄재배지역 남부평야 봄재배지역 남부해안 2기작 재배지역.남부 겨울재배지역.제주 가을 월동재배지역 등 7개 지역으로 구분되어 재배된다. 3. 우리나라(남한)의 감자 재배지의 중심지는 강원도 고랭지 여름재배지역과 제주도 가을 월동재배지역, 소백산맥과 진안고원이 만나는 부근 산지지역의 남원군.구례군 거창군.고령군과 남해안의 밀양군.양산군이다. 강원도 지역과 제주도 두지역이 전테 재배면적의 52%를 점유하여 감자 재배지의 핵심지를 이룬다. 4. 한국 감자 재배지역 중심지의 지리적 특징은, 높은 산지지역의 산록완사면에 밭작물로 재배된다는 점과 교통이 불편한 지역으로서 도시화와 산업화 지역의 그늘 지역이 대부분이다. 강원도의 감자 재배지는 감자재배에 적합한 자연환경과 화전농업의 전통, 감자 재배기술의 전파, 중앙정부와 지방정부가 지원하는 각종 연구소 분포와 영농지도, 씨감자 생산과 협동조합의 판로 개척, 도로 개설과 포장 등의 인문지리적 요인이 영농조건을 개선하고 감자 판매를 위한 시장접근을 용이하게 하여, 남한 최대의 감자 재배지역을 형성하였다. 제주도는 산지지형과 따뜻한 기온으로 2기작이 가능하고, 감자가공 공장설립과 교통발달에 따른 육지 시장과의 접근이 용이해졌기 때문에 남한에서 2번째로 큰 감자재배지역이 되었다.(요약 및 결론에서 발췌)

In 1631 A.D. Jeong Duwon, an ambassador of the Joseon dynasty was sent to the Ming dynasty. There he met $Jo\tilde{a}o$ Rodrigues, a Jesuit missionary, in Dengzhou of Shandong peninsula. The missionary gave the ambassador a number of results of latest European innovations. A detailed description on this event was written in 'Jeong's official report regarding a message from an European country'(西洋國奇別狀啓), which is an important literature work to understand the event. Since the document was written in classical Chinese, we make a comprehensive translation to Korean with detailed notes. According to the report, the items that Rodrigues presented include four books written in Chinese that describe European discoveries about the world, a report on the tribute of new cannons manufactured by Portuguese in Macao, a telescope, a flintlock, a Foliot-type mechanical clock, a world atlas drawn by Matteo Ricci, an astronomical planisphere, and a sun-dial. We discuss the meaning of each item in the Korean history of science and technology. In particular, Jeong's introduction is an important event in the history of Korean astronomy, because the telescope he brought was the first one to be introduced in Korean history. Even though king Injo and his associates of the Joseon dynasty were well aware of the value as military armaments of new technologies such as telescopes, cannons, and flintlocks, they were not able to quickly adopt such technologies to defend against the military threat of Jurchen. We revisit the reason in view of the general history of science and technology of east-Asian countries in the 17th century.
