This study analyzed the attitudes, expectations and Awareness for online Korean language education for teachers and learners who participated in the online King Sejong Institute curriculum. As a result of the survey, teachers preferred offline education to online education and had lower attitudes and expectations for online Korean education than learners. Unlike teachers, learners showed no difference in satisfaction between online and offline education, and their attitudes and expectations toward online education were also high. It was found that well-prepared online classes can be satisfactory to learners through the learners’ high attitudes and expectations for online Korean education. In addition, it was confirmed that online education, like offline education, satisfies learners by operating an appropriate curriculum and providing high-quality materials, and can sufficiently contribute to the improvement of learners’ language ability. It was found that teachers, unlike learners, had difficulties in conducting online education and did not have much confidence in the effectiveness of education. In particular, they complained of a lot of anxiety and difficulty about the unfamiliar teaching method, which is interpreted as reflecting the attitude of teachers who are familiar with real-time education. From this point of view, it can be seen that it is most important to provide teachers with the ability to utilize online teaching tools and implement various online teaching and learning in order to conduct online Korean language education. If appropriate teacher education for online education, provision of educational materials, and system support are provided, it is expected that teachers’ attitudes and awareness of online education will also increase.

동해 울릉분지 남서주변부는 탄화수소의 부존 가능성이 높은 대륙붕 환경으로 1990년대 말에 상업적 생산이 가능한 가스전이 발견된 바 있다. 가스전과 인접한 연구지역에서도 추가적인 가스개발을 위해 침식수로 내부의 조립질 퇴적체를 대상으로 시추가 수행되었지만 경제성이 부족한 것으로 판명되었다. 본 연구에서는 새로 취득된 탄성파 및 기존 시추 자료를 이용하여 울릉분지 남서주변부에 분포하는 침식수로 하부에 탄화수소 트랩 가능성이 있는 지질구조를 탐지하였다. 취득된 심부 탄성파 자료 및 시추자료 해석에 의하면 연구지역에 분포하는 퇴적층은 구조진화와 연계하여 열개동시성 퇴적층군(MS1), 후열개 퇴적층군(MS2), 횡압력 동시성 퇴적층군(MS3), 후횡압력 퇴적층군(MS4)으로 구분된다. 중기 마이오세 이전에 분지형성과 동시에 퇴적된 MS1은 주로 중-저진폭, 저주파수의 캐오틱 음향특성을 나타낸다. 중기 마이오세 동안 분지가 확장되며 다량의 퇴적물이 유입된 MS2는 중-저진폭의 음향특성과 함께 연속성이 양호하며 전진퇴적 양상을 나타낸다. MS3은 고진폭 및 중-고주파수의 연속성이 양호한 반사면을 나타내는데 이는 조립질 퇴적층으로 해석된다. 조립질 퇴적물이 우세한 MS3는 침식수로에 의해 광역적으로 삭박되었으며 침식수로 내부에는 MS4의 세립질 퇴적물이 충전되어 층서트랩을 형성한다. 따라서 연구지역의 트랩 구조는 MS3의 조립질 퇴적층이 저류층을 형성하며 MS4의 세립질 퇴적물로 충전된 침식수로가 덮개암으로 작용하는 층서 트랩으로 트랩 구조 내부에서는 탄화수소 부존을 지시하는 flat-spot 탄성파 이상대가 발달한다. A commercial gas field was found in the southwestern continental shelf of the Ulleung Basin, East Sea in the late 1990s. To develop additional gas field, an exploration well was drilled through the coarse infill of submarine canyon near the gas field, but it was uneconomic to develop hydrocarbons. Using newly acquired deep seismic reflection and previous well data, we have identified additional geological structure which has hydrocarbon potentials below submarine canyons in the southwestern margin of the basin. Based on the interpretation of the deep seismic reflection and well data, the sequences of the study area can be classified into the syn-rift megasequence(MS1), post-rift megasequence(MS2), syn-compressional megasequence(MS3), and post-compressional megasequence(MS4) in relation to the tectonic events. MS1, deposited simultaneously with the basin formation before the middle Miocene, is characterized by chaotic seismic facies with low- to moderate-amplitude and low frequency reflections. MS2 comprises laterally continuous, low- to moderate-amplitude reflections, showing progradational stacking patterns due to high rates of sediment supply during basin expansion in the middle Miocene. MS3 is mainly composed of continuous reflections with high amplitude and moderate- to high-frequency which are interpreted as coarse-grained sediments. The coarse-grained sediments of MS3 sequence is widely truncated by several submarine canyons which filled with fine-grained sediment of MS4 to form a stratigraphic trap of hydrocarbon. Therefore, the reservoir and seal of the hydrocarbon trap in the study area are coarse-grained sediment of MS3 and submarine canyon filled with fine-grained sediment of MS4, respectively. A flat-spot seismic anomaly, which may indicate the presence of hydrocarbon, is observed within the stratigraphic trap.

North Korea keeps developing nuclear weapon as well as various types of missile launchers, such as Transporter Erector Launcher(TEL), submarine launcher, and solid-fueled missile launcher to evade detection during launch preparation. As a defensive response to North Korea’s nuclear and missile threats, South Korea is continue researching and developing its own Kill-Chain, Korean Air and Missile Defense(KAMD), and Korean Massive Punishment and Retaliation(KMPR). However, South Korea’s Kill-chain system has a limitation on North Korea’s mobile missile launchers if real-time target information is not provided. Therefore, this study propose TEL pattern analysis which models TEL movement to improve this limitation. This study will contribute on strike location tracking and efficient military operation by proposing model which provides estimation on TEL movement pattern and subsequential strike location tracking.

This paper reviews the research on land reform in late Goryeo, and looks for new ways to advance the research. The existing research has important significance in the research history in that it provides a key explanation for understanding the character and development of the Korean medieval society. Nevertheless, not only is the evaluation of reforms diverging from the perceptions of the contemporaries, but also the results of the research are not in line with the actual development of the history of Joseon. The most important argument in the reform of the land system was that the private-land[私田] had to be abolished. The reforms were a process of completely transforming the land system, from which based on the private-land to which based on the sogyeongjeon[所耕田] and jeongaek[佃客] who cultivated the land. The economic and social relations of Goryeo continue until the beginning of the Joseon Dynasty despite the institutional change, and the gap between them defines the unique development of economic history of early Joseon.

제5의 전장인 사이버 공간은 전자기 스펙트럼을 이용하여 사이버 공간과 물리 공간 사이에서 다영역 기동에 활용될 수 있다. 이것은 사이버전과 전자전의 특징을 융합하는 사이버전자전의 주요 개념이 된다. 본 연구에서는 OSI 참조 모델을 활용하고, 2계층 데이터링크 계층의 위협 요소를 살펴봄으로써, 사이버 전자전 개념을 분석한다. The cyberspace, which is the fifth battle field, should be utilized for multi-domain maneuvering between the cyberspace and the physical space using an electromagnetic spectrum. This becomes a major concept of cyber electronic warfare that combines the characteristics of cyber warfare and electronic warfare. In this study, the concept of cyber electronic warfare is analyzed by using the OSI reference model and examining the threats of the two-layer data link layer.

The purpose of this study is development of online shelf-life monitoring system for low-temperature pasteurized milk. To monitor loss of milk shelf-life, we determined the bacterial growth as quality factor and temperature history as the variable. A number of storage experiments for pasteurized milk have been carried out with temperature range 5-40℃. Baranyi and Roberts model was used to predict bacterial growth in Pasteurized milk. The model determination factors were found to be 0.93 under constant temperature and 0.89 under varying temperature conditions.
