This study was conducted to understand media and cultivate personality by using media as data for personality education. To achieve this purpose, the Personality Education Promotion Act and the Korea Educational Development Institute's personality virtues were selected as educational elements, and a personality education program using media was developed in combination with the middle school curriculum. For this study, first, in order to extract personality virtues, 13 personality virtues were finally selected as educational elements by comparing and synthesizing the personality virtues of the Personality Education Promotion Act and the Korea Education Development Institute. The final personality virtues selected are self-esteem, courage, sincerity, self-regulation, wisdom, consideration, communication, courtesy, social responsibility, cooperation, citizenship, justice, and respect for human rights. Second, in order to select media and set the direction of development of personality education programs, the process of collecting media data was confirmed, and the direction and goal of the program were set by analyzing the middle school curriculum. Third, in order to propose a method of applying a personality education program using media, the personality grafting unit was selected by referring to the commentary on all subjects of the 2015 revised curriculum.

Recently, research and development on satellite payloads are being developed such as the optical sensor, SAR etc. Satellite image for earth observation is being utilized both domestically and abroad. Advanced satellite payload technology has led to the collection and analysis of satellite images relying on the optical sensor. Currently, related organizations such as RDA(the Rural Development Administration) are collectively collaborating to plan a national project to develop a medium-sized satellite based on Korea's domestic technology independently. This paper investigated the cases of the past research on application of satellite images for agriculture and analyzed the technical specifications for satellite payload in each area of such application. Based on the results of the past surveys and consultation studies among local experts in satellite image application, we analyzed the current trends, plans and applications of domestic and overseas R&D in satellite payloads for earth observation in agriculture, and proposed the appropriate technical specifications for developing a future medium-sized satellite for agriculture. The proposed specifications were then incorporated into a simulated satellite to examine its performance to observe the Korean farming areas. The authors anticipate that the findings of this paper will form a useful technical basis for providing the appropriate specifications for developing future medium-sized satellite payloads to be used in agriculture and forestry, and enabling the end users to efficiently utilize the satellite.

This paper presents to develop a path planning algorithm combining gradient descent-based path planning (GBPP) and particle swarm optimization (PSO) for considering prohibited flight areas, terrain information, and characteristics of fixed-wing unmmaned aerial vehicle (UAV) in 3D space. Path can be generated fast using GBPP, but it is often happened that an unsafe path can be generated by converging to a local minimum depending on the initial path. Bio-inspired swarm intelligence algorithms, such as Genetic algorithm (GA) and PSO, can avoid the local minima problem by sampling several paths. However, if the number of optimal variable increases due to an increase in the number of UAVs and waypoints, it requires heavy computation time and efforts due to increasing the number of particles accordingly. To solve the disadvantages of the two algorithms, hierarchical path planning algorithm associated with hierarchical particle swarm optimization (HPSO) is developed by defining the initial path, which is the input of GBPP, as two variables including particles variables. Feasibility of the proposed algorithm is verified by software-in-the-loop simulation (SILS) of flight control computer (FCC) for UAVs.

The aim of this study was to enhance the safety and care of mental health for seafarer working in passenger ship workspaces. Brightness, color values, and color distribution were investigated with issues and improvement ways identified through seafarers' interviews. Firstly, previous studies, references, current policy, regulations, and accident case studies were reviewed. Color compositions of wheelhouse and engine room of M Ship were then surveyed in the field. Color values of each space were analyzed using a colorimeter. Colormeter analysis of brightness and color measurements in the wheelhouse and engine areas indicated that ceilings, walls, and floors were generally dark, with the engine area being very dark. Regarding color, green and blue were distributed in the ceiling of the wheelhouse and engine area, while red and blue were in the walls and floors of the wheelhouse and engine area. According to interviews with seafarers currently working at engine rooms, they responded about their experience of near miss incidents due to a decrepit indoor environment, a dark working environment, slippery and bright flooring, and stairs that were not suitable for domestic users. Thus, when installing lighting in the future, the brightness of the space should be improved by distinguishing between night and day. A lighting plan considering the location of lighting, level of shadow formation and contrast, reflectance of the facility, glare, color of light, floor color plan, and material selection is needed. A facility design suitable for domestic users is also needed.

주차금지, 일방통행. 본 논문에서의 횡단보도와 같은 교통표지는 개별적 행위로서 행정행위가 아니라 불특정 다수의 행위를 추상적으로 규율하는 특성을 지닌다. 현행 도로교통법상 횡단보도의 설치여부는 지방경찰청장의 재량 사항으로 규정되어 있어 경찰이 횡단보도를 새로 설치하거나 기존의 횡단보도를 폐지하는 경우 관할 경찰청은 물론 관계 행정청에 이를 설치 혹은 폐지해달라는 민원이 매우 많아 일선 경찰공무원 등이 많은 애로를 느끼고 있으며 급기야는 본고에서 검토할 사례의 경우와 같이 행정소송을 통해 뜻을 관철하고자 하는 경우까지 생겼다. 횡단보도의 설치와 관련한 대법원 판결(대법원 2000.10.27.선고, 98두8964판결)이 이제 처음 나왔지만 시민의 권리의식의 향상에 따른 소송의 증가경향으로 미루어 앞으로 이와 유사한 문제제기는 더욱 늘어날 것으로 전망된다. 이에 본고에서는 횡단보도의 설치와 관련한 행정소송에 대한 최근 대법원판결에 대한 심층분석을 통하여 그 의미와 문제점을 지적함으로써 앞으로 이와 유사한 사례에 대한 판단에 있어 방향성을 제시하였다. 즉 횡단보도 설치행위의 적법성과 관련한 소송에서 가능한 본안심리를 통해 국민의 권익구제의 기회 내지 가능성을 열어주는 것이 바람직하다는 점과 현재 원고적격의 범위가 확대되어 가고 있는 추세에 비추어 앞으로 횡단보도의 설치와 관련한 원고적격의 범위 역시 확대되는 것이 바람직하다는 방향에서 법규정에 대한 새로운 해석을 시도하였고 이를 통해 횡단보도의 설치 및 폐지에 따른 경찰 등 관계 행정청의 관심과 신중을 촉구하였다. 또한 횡단보도 설치행위의 처분성과 관련하여 횡단보도의 설치행위와 같은 일반적인 명령을 항고소송의 대상으로 할 필요성이 존재한다면 이른바 독일에서의 일반처분이라는 개념을 무리하게 받아들여 이를 행정행위의 한 유형으로 한다거나 우리 판례와 같이 "직접적이고 구체적인 법적 효과"를 미치는 명령이라는 명확치 않은 기준에 의하여 처분성을 인정하기보다는 일반적인 명령과 개별적인 행정행위를 구분하고 명령에 대하여도 취소소송의 대상으로 삼도록 하는 보다 명확하고 일관성 있는 논의전개를 제안하였다.
