Interest and investment in drones that apply the concept of the 4th industrial revolution and ICT convergence advanced technology are continuing. The purpose of drone operation has been widely spread from the initial military use to the use of various industries such as construction, forestry, facilities, and agricultural support. In these industries, the training of pilots who can actually operate drones is increasing centering on the qualification system. However, the detailed standards including the training place, training place, educational environment, and education method for nurturing pilots are ambiguous, so the education through the oral instruction of the training instructor is continuing at the drone training site. In order to solve this problem, this study conducted a study on a dual control platform in which a training instructor could directly intervene in the pilot's flying drone to execute a map in order to improve the quality of synesthesia, which is essential in the field.

The baby boomers born between 1955 and 1974, recently called the new age, form a huge population group and show characteristics different from the previous traditional older generations. With the retirement of those who make up 33% of the nation's population in earnest, the emergence of a new generation of the elderly population and policy changes are required. The new middle age generation, also called the opal generation, want to spend their old age productively and autonomously, which has increased due to the increase in life expectancy, and have some economic ability, such as enjoying overseas travel in old age. As preparation for old age is insufficient, policy attention is required for the younger generation as a new generation. In this paper, focusing on the baby boom generation, the definition of the opal generation, their consumption lifestyle, attitudes, social activities, leisure activities, and lifestyle such as health efforts are investigated, and job creation, social re-education, and local It is intended to present practical measures for preparing for old age, such as the establishment of medical facilities and social consideration for a leisurely cultural life.

Sense-Making Theory gives persuasive power to information seeking behavior while acknowledging the diversity of subjects. It is being used as a theory and methodology to explain the phenomenon of information seeking in various temporal and spatial contexts related to the communication of individuals' inner realms, face-to-face, organization, and mass communication. However, it is not to be a theory to explain the information seeking behavior of a group in that it explains the individual epistemological interpretation of the subjects. Also, the purpose of the theory was to establish a receiver-centered communication theory that constructs sense-making by itself, away from the receiver who unilaterally accepts the sender's information from the perspective of communication theory. However, Dervin accepted the existence of object information without explaining the relationship between the recipient's external information and the receiver. Owing to the establishing his concept of information following the Popper(1972)'s world concept, its object of observation is not World III(objective content of thought), but the process of sense making in which World II(psychological world) receives information generated in World III. In this context, Dervin's theory is not to explain the communication behavior at a group level.

As many different over-the-top (OTT) services become ubiquitous, demands for high-quality content are increasing. However, high dynamic range (HDR) contents, which can provide more realistic scenes, are still insufficient. In this regard, we propose a new HDR video reconstruction technique using multi-exposure low dynamic range (LDR) videos. First, we align a reference and its neighboring frames to compensate for motions between them. In the alignment stage, we perform content-based alignment to improve accuracy, and we also present a high-resolution (HR) module to enhance details. Then, we merge the aligned features to generate a final HDR frame. Experimental results demonstrate that our method outperforms existing methods.

북한강 유역은 대한민국을 대표하는 한강의 제1지류로 상류에 북한산이 위치하여 풍부한 자연환경과 생태계를 보유하고 있다. 해당 유역은 수력 및 다목적댐이 위치하여 수력발전과 수도권 물공급에 있어 중요한 역할을 하고 있다. 더욱이, 상수원보호구역으로 지정되어 있어 수질오염 예방을 위한 수질 관리가 필요하다. 기존 연구의 경우 북한강 유역 내 1개 다목적댐(소양강댐) 지점에 대한 수량 및 수질 매개변수 검·보정을 수행한 사례가 있으나 다목적댐 및 수력댐을 모두 고려한 사례는 없어 관련 연구가 요구되는 실정이다. 본 연구에서는 SWAT 모형을 활용한 북한강 유역 내 수량·수질을 분석 및 평가하고자 한다. 대상유역은 북한강 유역이며 저류를 하지 않는 평화의 댐을 제외한 5개 댐(화천댐, 춘천댐, 소양강댐, 의암댐, 청평댐)에 대해 모형에서 고려하였다. 자료평가기간은 1983년부터 2021년이며 기상 및 지형자료, 저수지 자료, 점오염원 자료를 입력자료로 활용하였다. Penman/Monteith 방법, SCS 방법, Muskingum 방법, 저수지 운영 방법(일 단위 관측 방류량 입력 및 목표 저수량 유지)을 활용하여 모형 모의를 수행하였다. 매개변수 검·보정은 수량(댐 유입량 및 방류량, 저류량) 및 수질(유사량, 총질소, 총인) 자료를 활용하여 수량 9개 지점과 수질 6개 지점, 댐 저수지 5개 지점을 중심으로 수행하였다. 수량 및 수질에 대한 도시적 및 통계적 평가를 통해 관측 및 모의 간의 정확도를 평가하였다. 평가결과, 수량은 임남댐의 영향을 받는 일부 댐을 제외한 대부분의 댐 유역에서 관측 및 모의 유량 간의 적합도가 우수하게 나타났다. 수질은 수량의 영향을 직접적으로 받아 일부 지점을 제외한 대부분 지점에서 관측 및 모의값 간의 적합도가 높게 나타났다. 검·보정 적절성 판단을 위한 정량적 평가결과, 수량의 경우 결정계수(R²) 0.64~0.94, 용적오차(PBIAS) 0.09%~15.77%로 적정한 것으로 나타났다. 수질의 경우 용적오차 0.00%~29.14% 사이로 적정범위 안에 포함된 것으로 나타났다. 본 연구결과는 기후변화와 연계하여 미래 기간의 수량 및 수질 분석 연구에 기여할 것으로 기대된다.
