In this paper, we propose a novel tracking method using target separation and detection that are based on discriminative correlation filter (DCF), which is studied a lot recently. ‘Retainability’ is one of the most important factor of tracking. There are some factors making retainability of tracking worse. Especially, fast movement and occlusion of a target frequently occur in image data, and when it happens, it would make target lost. As a result, the tracking cannot be retained. For maintaining a robust tracking, in this paper, separation of a target is used so that normal tracking is maintained even though some part of a target is occluded. The detection algorithm is executed and find new location of the target when the target gets out of tracking range due to occlusion of whole part of a target or fast movement speed of a target. The algorithm proposed in this paper showed better performance than other conventional algorithms when fast movement and occlusion of a target occur..

乾隆49년(1784)~50년(1785)의 敎案과 天主敎共同體

李俊甲(Lee, Jun-gab) 동양사학회 2011 東洋史學硏究 Vol.117 No.-

In this study I have analyzed the persecution on the missions occurred in Guangdong, Hunan, Hubei, Shanxi, Shandong, Jiangxi, Gansu, Sichuan, Henan, Hebei, Fujian during the years 1784-1785 by Qing dynasty and the aspects of Catholic community. As the persecution on the mission was taken place in late Qianlong period, so the two characteristics of the bureaucracy at that time, corruption and incompetence were reflected in the process of handling it. Persecution on the mission was not efficiently executed because of the corruption and incompetence of the local bureaucrats. While they were occupied with robbing missionaries of silver, copper cross on the spot of arresting the missionaries, a Chinese Catholic and interpreter could made a quick getaway. Some of the bureaucrats gave their superior bureaucrat or Emperor Qianlong in order to conceal their corruption and incompetence. Because of the bureaucrat’s corruption and incompetence, the Qing government revealed many holes in the policy of persecution on the missions in late Qianlong Period, various Catholic community could continue to exist. According to the basis of local criteria, there were two types of Catholic communities. One was the wide area Catholic community composed of Catholics who lived in two or more counties, the other was the narrow area Catholic community composed of Catholics who lived in a county. According to the basis of function criteria, there were two types of Catholic communities. One was the typical Catholic community in which members put stress on Bible study, the other was the variant community in which members put stress on interrelationship without Bible study.

탄소중립 이행과 정의로운 전환을 위한 법적 과제

The Framework Act on Carbon Neutrality and Green Growth to Respond to the Climate Crisis (Carbon Neutrality Framework Act), enacted on September 24, 2021, reflects the carbon-neutral policies and legislative trends of major countries, including the recommendations of the IPCC. The Act declared the goal of achieving carbon neutrality by 2050. Policies and plans related to climate change response and adaptation, energy policy, and greenhouse gas reduction laid out in the Carbon Neutrality Framework Act were already covered by the Framework Act on Low Carbon, Green Growth, but the concept of the “Just Transition” was interwoven into the Carbon Neutrality Framework Act for the first time. The abolition of coal-fired power generation or the reduction of nuclear power plants―examplary cases of energy conversion― when gradually implemented over a long period of time, would pose no excessive strain during transition. In order to achieve carbon neutrality by 2050, however, there is no choice but to reorganize the industrial system at a considerable rate. To implement carbon neutrality within the next 10 to 30 years, countermeasures must be prepared to reduce the resulting impact on industries, jobs, and the local economy. Just Transition is a solution to the need for a rapid clean energy transition. In other words, it means to socially share the burden on the region and industry in the process of implementing the carbon neutrality goal, and to reorganize the industrial system while minimizing direct and indirect damage to related stakeholders. Carbon neutrality and just transition intertwined in the policy is also shown in the US "Green New Deal Resolution", Korea"s "Energy Transition Roadmap", and "The 3rd Green Growth Plan" as they incorporate regional and industrial supplementary measures to lighten the weight the clean energy transition brings. In Carbon Neutrality is a goal that we must achieve to prepare for the climate crisis. Policies related to carbon neutrality, however, will have a negative impact on large-scale carbon emission industries, on energy-intensive industries, and on industries that consume loads of fossil fuels. The Carbon Neutrality Framework Act suggests policies for a just transition, such as the establishment of a social safety net, designation of a special district for just transition, support for business conversion, minimization of risk of asset loss, support for guaranteeing public participation, development of cooperatives, and establishment of a just support center. These provisions are merely declarative and abstract in nature that they lack specific steps to implement policies for a just transition. Energy transition and just transition are to expand the use of renewable energy that does not cause a climate crisis, to enjoy basic energy services for all members of society, to share the burden generated in the transition process socially, and to minimize damage to the vulnerable. In order to successfully achieve a just transition, it is necessary to make an effort to solve the problems of the local economy that is dependent on fossil fuels and coal-fired and nuclear power generation so that a soft landing to a carbon-neutral society can be attained. In addition, it is necessary to prepare for employment conversion through education and training while rendering accurate and specific definition of green industries and green jobs.

이기지(李器之)(1690~1722)의 『일암연기(一菴燕記)』에 묘사된 ‘작은 서양(西洋)’

이준갑 ( Lee Jun-gab ) 인하대학교 한국학연구소 2016 한국학연구 Vol.0 No.43

본고는 이기지가 저술한 『일암연기』에 나타난 서양의 모습을 전반적으로 검토하려는 목적에서 집필하였다. 『일암연기』는 현재까지 알려진 연행록 가운데 서양인과 천주당 관련 기록을 가장 자세하고 풍부하게 담고 있고 이들에 대한 객관적 시각도 갖추고 있다. 천주당이라는 극히 제한된 공간과 연행 기간 동안이라는 짧은 시간 속에서 그가 만나 서양인이 극소수이고 그가 경험한 서양 문물도 극히 제한적이었다는 사실을 고려하면 『일암연기』에서 묘사한 서양은 ‘작은 西洋’이었다. ‘작은 서양’을 구성하는 천주당 공간은 別世界라고 표현되었을 정도로 이기지에게 색다르게 다가왔다. 그 공간은 입구에서부터 맞은편 제단까지 거리가 길고 좌우 폭이 좁은 긴 직사각형 모양의 서양식 공간이었다. 좁고 긴 공간은 스테인드글라스를 통해 들어오는 서양식 빛 때문에 실내가 밝았다. 서양식 공간과 서양식 빛 속에서 이기지는 사해동포로서 마음이 통하는 서양인들을 만나고, 생동감과 입체감이 넘치는 종교화를 감상했다. 제작 기술이 사람의 솜씨를 초월한 듯이 신기하고 정교한 서양 기물을 만지고 작동시켜 보았으며 갖가지의 다른 서양 것들을 체험해 보았다. 이기지는 서양 화법이나 기물 제작 기술의 정교함에 감탄을 거듭했고 그 정교함을 탄생시킨 서양 학문의 정묘함을 인정하게 되었다. 『일암연기』에서 서양인은 華夷論으로 멸시하는 대상으로 묘사되지는 않았다. 오히려 사해동포라는 관점에서 서로 대등하며 더불어 살아가는 존재로서 인식되었다. 『일암연기』에는 일방적인 배척과 수용이 아닌 중립적이고 객관적인 입장에서 서양을 바라보는 시선이 담겨 있다. 18세기 전반 ‘작은 西洋’을 체험했던 조선 지식인이 가졌던 대외 인식의 유연성을 『일암연기』에서 엿볼 수 있다. 이런 그의 태도는 18세기 이후 이익을 비롯한 일군의 학자들이 西器中國原流說을 수용하여 ‘문화중심의 화이론’을 견지했던 것과는 무척 대비된다. The purpose of this study is to examine the character of the western world depicted in Ilamyeongi written by Leegiji. There are a lot of contents intimately related with westerner and Catholic church at Beijing in Ilamyeongi. So we can say that Ilamyeongi is the most important document to study the way of Joseon literati’s understanding western world. In this study, I defined the western world depicted in Ilamyeongi as ‘the small western world’, because Leegiji's travel to Beijing was so short that he could not get enough information on western civilization and institutions. In spite of the restricted circumstance, Leegiji visited Catholic church and met missionaries in Beijing as much as possible. He saw and operated many instruments from western world in Catholic church. After that, he found that western instruments and scientific technique were very accurate. So he understood western world with objective attitude which was very different from most other Joseon litrerati's sino-barbarian theory.

軍事施設 所在 古代 關防遺蹟의 관리 · 활용 방안 -임진강 · 한탄강 유역을 중심으로-

이준성(Lee, Jun-sung) 고조선단군학회 2021 고조선단군학 Vol.45 No.-

본고에서는 임진강 · 한탄강을 중심으로 군부대 및 군사시설 내에 위치하고 있는 고대 관방유적의 사례를 살펴보고, 관리 및 활용 방안을 제시하였다. 임진강 · 한탄강 유역은 삼국의 영역 확장 과정에서 오랜 기간 격전이 벌어진 경계 지대로서 다른 지역들에 비해 고대 관방유적이 많이 배치되어 있는 곳이다. 동시에 한국전쟁 이후 지금도 남과 북이 대치하고 있는 곳이기도 하다. 이러한 지역적 특성으로 인해 그동안 이 지역의 고대 관방유적에 관한 연구와 보존, 정비와 관련하여, 많은 수의 해당 유적이 군사시설이나 민간인 출입통제선(민통선) 지역에 분포하여 있다는 점이 제약사항으로 거론되어왔다. 이에 관한 해결책을 모색하는 과정에서 지난 2016년 제정된 「군 문화재보호 훈령」을 주목하였고, 그에 기반하여 관리 · 활용방안을 살폈다. 특히 「훈령」에 명시되어 있는 ‘군사재’의 개념을 활용하여 제도적인 측면에서 해결책을 찾을 수 있는 가능성을 상정해 보았다. 뿐만 아니라 ‘한 문화재 한 지킴이’, ‘문화재 돌봄사업’ 등 기존에 이미 마련되어 있는 정책을 활용하거나, 문화재청과 국방부가 진행하고 있는 ‘군 문화재 관리 역량 강화 교육’을 강화하는 것 역시 필요한 조치로 판단하였다. One of the constraints on the study and preservation of ancient fortress remains is that a large number of remains exist within military facilities. This is due to the fact that geopolitical conditions such as transportation routes and waterways of the Imjin River and Hantan River have not changed much since ancient times, and that the area that was a key military point in the past is still a key point. 「The Ordinance on the Protection of Military Heritage」, enacted in 2016, helps establish measures to manage and utilize these remains. This is because the concept of ‘military assets’ included in the Ordinance can be used to find solutions in an institutional aspect. In addition, it is also necessary to consider actively applying the existing cultural heritage utilization policies that the Cultural Heritage Administration has already implemented to the fortress remains that exist in military facilities.

Geant4 코드를 이용한 선형가속기 6 MV 광자선의 선량분포에 관한 연구

이준성(Jun-Seong Lee),김양수(Yang-Soo Kim),이선영(Sun-Young Lee) 대한방사선과학회(구 대한방사선기술학회) 2022 방사선기술과학 Vol.45 No.5

This study is to present a Geant4 code for the simulation of the absorbed dose distribution given by a medical linac for 6 MV photon beam. The dose distribution was verified by comparison with calculated beam data and beam data measured in water phantom. They were performed for percentage depth dose(PDD) and beam profile of cross-plane for two field sizes of 10 × 10 and 15 × 15 cm² Deviations of a percentage and distance were obtained. In energy spectrum, the mean energy was 1.69 MeV. Results were in agreement with PDD and beam profile of the phantom with a tolerance limit. The differences in the central beam axis data δ1 for PDD had been less than 2% and in the build up region, these differences increased up to 4.40% for 10 cm square field. The maximum differences of δ₂ for beam profile were calculated with a result of 4.35% and 5.32% for 10 cm, 15 cm square fields, respectively. It can be observed that the difference was below 4% in δ₃ and δ₄. For two field sizes of δ50-90 and RW50, the results agreed to within 2 mm. The results of the t-test showed that no statistically significant differences were found between the data for PDD of δ1, p>0.05. A significant difference on PDD was observed for field sizes of 10 × 10 cm², p=0.041. No significant differences were found in the beam profile of δ₃, δ₄, RW50, and δ50-90. Significant differences on beam profile of δ₂ were observed for field sizes of 10 × 10 cm², p=0.025 and for 15 × 15 cm², p=0.037. This work described the development and reproducibility of Geant4 code for verification of dose distribution.
