In this study, a direction for deregulation that can increase the use of drones in the field of spatial information is presented. Regulations and administrative procedures for drone operation showed similar procedures in Japan, the United States, and Korea, such as reporting flight equipment, driver's license, and prohibition of flying within a specific flight zone. In the United States, policies to encourage the use of commercial drones have been implemented, and Japan has slightly tightened regulations on drone operation to protect the Olympics and important national facilities. As a result of the study, in the area where drone operation is restricted for geospatial data construction, Korea was setting the largest area, and GIS analysis showed that Korea's drone flight restricted area was more than 19.4% of the country's land area. In order to increase the utilization of drones in the construction and utilization of spatial information in the future, it is necessary to reset the drone flight restriction zone and reduce the area of the drone flight restriction zone. In addition, it was found that Korea is the only country that has formal and specific regulations on geospatial information security management. In order to increase the construction of geospatial information using drones, it is necessary to ease GSD (Ground Sample Distance)regulations.

As a series of research plan, this study is to provide basic data necessary for the development of fishing industry which will contribute in establishing sound fishing culture in Jeju island through systematic management of fishing, protection of fishery resources and establishment of safety measures for fishermen in accordance with 'Fishing Management and Support Act'. To attain the proposed objective, this study conducted literature review and surveys on restriction standards of harmful substances generated from fishing equipment and baits, examined the current status of fishing management in popular fishing sites of other cities, and then reviewed and analyzed the fishing management and fishing-restriction zones in Jeju island. The survey on the opinions on the restriction criteria of fishing methods, tools and period, including the acceptable standards for harmful substances showed that general fishermen preferred 'alleviating the measure (44.8%)' to 'aggravating the measure (23.0%)'. Meanwhile, maritime police showed dominant opinion toward 'aggravating the restriction (52.2%)' over 'alleviating the measure (4.3%)'. Furthermore, fishing-related enterprise is favored 'aggravating the restriction (32.6%)' over 'alleviating the measure (27.9%)'. In the survey on the tolerance of fishing baits including criterion for content of certain substance in different types of bait, it showed 57.5% of general fishermen preferred alleviating restriction criteria while 20.7% of them favored tougher restriction. Whereas, 33.3% of maritime police group insisted such fishing baits should be more restricted while 16.7% answered it should be alleviated. 35.9% of fishing-related enterprise was in favor of alleviation while 14.3% preferred aggravation. Upon investigation on the status of fishing management in other cities and towns, it turned out that most of them had safety and convenience facilities, installed warning and guide signs in fishing sites, and set no fishing zones. The review of fishing management and restricted area showed that 10 sites required access restriction and 2 of 10 sites were considered to be partially restricted for weather and season. 82 fishing sites were regarded as unnecessary to be restricted and installation of safety facility and guide signs is necessary for the safety of fishermen.

With its technical development, digital printing is being universally introduced to the mass production of clothing factories. At the same time, many fashion platforms have been made for customers' participation using digital printing, and a tool is provided in platforms for customers to make designs. However, there is no sufficient solution in the production stage for automatically converting a customer's design into a file before printing other than designating a square area for the pattern designed by the customer. That is, if 30 different designs come in from customers for one shirt, designers have to do the work of reproducing the design on the clothing pattern in the same location and in the same angle, and this work requires a great deal of manpower. Therefore, it is necessary to develop a technology which can let the customer make the design and, at the same time, reflect it in the clothing pattern. This is defined in relation to the existing clothing pattern with digital printing. This study yields a clothing pattern for digital printing which reflects a customer's design in real time by matching the diagram area where a customer designs on a given clothing model and the area where a standard pattern reflects the customer's actual design information. Designers can substitute the complex mapping operation of programmers with a simple area-matching operation. As there is no limit to clothing designs, the variousfashion design creations of designers and the diverse customizing demands of customers can be satisfied at low cost with high efficiency. This is not restricted to T-shirts or eco-bags but can be applied to all woven wear, including men's, women's, and children's clothing, except knitwear.

Self-assembled monolayers(SAM) of microspheres such as silica and polystyrene(PS) beads have found widespread application in photonic crystals, sensors, and lithographic masks or templates. From a practical viewpoint, setting up a high-throughput process to form a SAM over large areas in a controllable manner is a key challenging issue. Various methods have been suggested including drop casting, spin coating, Langmuir Blodgett, and convective self-assembly(CSA) techniques. Among these, the CSA method has recently attracted attention due to its potential scalability to an automated high-throughput process. By controlling various parameters, this process can be precisely tuned to achieve well-ordered arrays of microspheres. In this study, using a restricted meniscus CSA method, we systematically investigate the effect of the processing parameters on the formation of large area self-assembled monolayers of PS beads. A way to provide hydrophilicity, a prerequisite for a CSA, to the surface of a hydrophobic photoresist layer, is presented in order to apply the SAM of the PS beads as a mask for photonic nanojet lithography.

Automatic Video Surveillance System (AVSS) has become important to computer vision researchers as crime has increased in the twenty-first century. As a new branch of AVSS, baggage detection has a wide area of security applications. Some of them are, detecting baggage in baggage restricted super shop, detecting unclaimed baggage in public space etc. However, in this paper, a detection & classification framework of baggage is proposed. Initially, background subtraction is performed instead of sliding window approach to speed up the system and HSI model is used to deal with different illumination conditions. Then, a model is introduced to overcome shadow effect. Then, occlusion of objects is detected using proposed mirroring algorithm to track individual objects. Extraction of rotational signal descriptor (SP-RSD-HOG) with support plane from Region of Interest (ROI) add rotation invariance nature in HOG. Finally, dynamic human body parameter setting approach enables the system to detect & classify single or multiple pieces of carried baggage even if some portions of human are absent. In baggage detection, a strong classifier is generated by boosting similarity measure based multi layer Support Vector Machine (SVM)s into HOG based SVM. This boosting technique has been used to deal with various texture patterns of baggage. Experimental results have discovered the system satisfactorily accurate and faster comparative to other alternatives.

다중 시기 KOMPSAT-3/3A 고해상도 위성영상을 이용하여 후쿠시마 제1 원자력 발전소 주변 지역에 대한 식생지수를 산출하고 식생 변화의 양상을 분석하였다. 식생지수 산출 시에는 KOMPSAT-3/3A 위성영상의 지표반사도를 사용하였다. 4개 연도의 위성영상을 사용하였으며 이 영상이 중첩되는 지역을 연구의 대상이 되는 관심영역으로 정하였다. 자료 분석 방법으로 주로 식생이 분포하는 지역을 지나가는 측선을 설정하여 연도별 변화 양상을 살펴보았다. 또한, 2차원 공간상의 식생지수의 변화를 정량적으로 나타내기 위하여 관심영역 내에서 랜덤 포인트를 추출하여 상자그림으로 나타내었다. 연구의 주요 결과는 원전 인근 지역에서 2014년 식생지수는 관심영역 내에서 낮은 값으로 나타났지만 이후 2021년까지 지속해서 식생이 발달하고 있는 것으로 나타났다. 이러한 결과는 측선이나 상자그림으로 나타낸 변화 모니터링 결과에서도 확인할 수 있었다. 현장 자료를 수집하기 어려운 후쿠시마 원전 지역과 같이 접근이 제한되는 재난 지역에서는 위성영상을 이용하여 높은 정확도를 갖는 토지 피복 분류 산출물을 얻기가 어렵기 때문에 고해상도 위성영상 정보부터 얻는 식생지수와 같이 기본적인 산출물을 이용하여 분석하는 방식이 적절하다. 한편 국제적으로 공동 활용이 가능한 위성정보 자원의 활용 체계 구축과 함께 우리나라에 영향을 줄 수 있는 주변국의 환경 변화를 주기적으로 모니터링하기 위하여 고해상도 위성영상을 이용한 활용 모델과 시스템을 구축할 필요가 있다.

연안관리 계획은 연안을 이용방향에 따라 4개의 구역으로 분류하도록 하고 있는데, 각 구역별 연안이용행위의 금지 및 지원사항을 정하도록 하고 있다. 연안구역을 설정할 경우 해당지역이 국토이용계획 및 도시계획에 따라 지역 및 지구로 이미 지정되어 있어 추가적인 구역 설정시 이 같은 점이 중요한 검토기준이 되기도 하지만 경우에 따라서는 상충되는 결과를 초래할 수도 있다. 따라서, 연안관리에 있어서의 범위와 이용구역의 설정에 대한 검토 요소를 분석하고, 기존의 지역 지구지정 현황과의 상충문제 해결을 위한 방안을 도출하기 위한 노력이 필요하다. 보다 정확하고 효율적인 연안관리를 위해 해양에서의 해양공간계획과 토지에서 활용되는 도시계획제도와 지적제도를 활용하여 연안지역을 등록 관리할 필요성이 있다. 이를 위해 국토이용계획, 해양공간계획 등을 종합한 계획을 수립할 수 있는 별도의 협의체 기관 검토, 다른 개별법이 정하고 있는 각종 구역 지역의 지정 상충 검토, 연안해역의 범위 설정(3해리 내), 연안등록 방안 및 등록 대상 등을 모색하였다.
