인터넷의 급속한 발달과 이미지 콘텐츠 개발 기술의 발달로 현재 누구나 쉽게 이미지 콘텐츠의 공유 및 배급이 용이해졌다. 그러나 이로 인해 누드나 포르노와 같은 불건전한 유해 이미지들의 접근 역시 쉬워지고 있다. 특히, 스마트 폰이나 스마트 TV 등 멀티미디어 기능이 가능한 휴대장치 및 단말기의 비약적인 발전으로 인하여, 언제 어디서나 우리들은 유해 이미지의 노출되어 있다. 따라서 유해 이미지 시청이 적당하지 않은 연령층까지 무방비 상태에 놓여 있기 때문에 이를 막을 수 있는 시급한 대책이 요구되고 있다. 본 논문에서는 이중 피부 화소 검출에 이용하여 인체 영역 검출해내고 이것을 이용하여 유해 이미지 분류를 위한 방법을 제안하고자 한다. 일반적으로 피부 화소 검출 기법은 오차율을 가지고 있기 때문에 정확한 검출이 힘들다. 따라서 우리는 검출에 대한 강도를 조절하여 이중으로 피부 화소를 검출하여 좀더 정확한 피부 영역을 획득한다. 또한 기존의 방법들은 대체로 일차적인 피부 영역 검출에 초점을 둔 반면, 유해 판별의 주된 기준이 되는 가슴이나 성기, 엉덩이 등을 좀 더 중점적으로 찾으려 하지 않았다. 따라서 본 논문에서는 검출된 피부 영역에서 유해 부위를 좀 더 집중적으로 찾아 유해 판별 성능을 높이는 방법을 제안하고 실험으로 증명을 하고자 한다.

This study investigated how people perceived the importance of health message design principles including gist presentation, usefulness of content, format, and intuitive design and how well a webzine article published by Korean Ministry of Food and Drug Safety was designed in terms of the four design principles. This study also explored what individual characteristics influenced the perceptions of health message design principles. A total of 294 adults participated in the survey, and their responses were analyzed with the Importance-Performance Analysis method. Participants perceived that usefulness of content was most important in the text design; gist presentation was most important in the visual design; and format was well designed in both text and visual messages. This study showed that it is crucial to improve the quality of visual health messages particularly in terms of gist presentation and intuitive design. We also found that individuals' interest in health played a significant role in the perceptions of health messages. These results were discussed in regards to principles and strategies for the effective design of health messages.

Weapon, command, and communication system have been continually developed in the Korean military since last several decades. However, it is always asked to make a more effort on improving the ability of combat capability through people in order to achieve and maximize military power. In terms of improving the battlefield leadership, this research focused on ROTC(Reserve Officers'Training Corps), because the training junior officers lays a great foundation on basic strength of the military. This study theoretically and empirically examined the ROTC's quality and effectiveness of leadership. The proposed research model and hypotheses are mainly composed of four factors: personality, esprit de corps, and professionalism as independent variables; leadership effectiveness as a dependent variable. The empirical result revealed that esprit de corps, professionalism, and personality have a meaningful influence on leadership effectiveness. It is suggested that an ongoing training and education program of leadership for ROTC should be applied for achieving a better leadership effectiveness on the battlefield.

The private security has achieved a rapid growth by playing an important role in supporting the public security. However, there are some negative results of this rapid growth. Violence committed by the private security is the biggest problem among them. This study discuss the necessity of eradicating violence committed by the private security, present some violence cases, and find solutions to the problem resulting from the cases. If violence committed by the private security is not eradicated, advancement in the private security service industry can not be expected. This study suggests the three possible solutions: reinforcing regulations restricting violence committed by the private security; strenthening the responsibility of the private security company (employer) for supervision and management on the private security guard (employee); establishing the philosophical identity of security service.

본 팀은 웹캠으로 촬영한 영상에서 원하는 물체를 선택하여 텍스처를 선택한 이미지의 스타일로 변환하는 프로젝트를 수행했다. 영상을 세그멘테이션하고 원하는 물체만을 원하는 텍스처로 변환하여 최종 아웃풋을 얻는다. 제안하는 네트워크는 물체를 다양한 스타일로 바꾸는 것이 가능한데, 이 중에서 이미지에 명화의 화풍을 입히는 것을 중점으로 하여 데모를 구현했다. 빠른 속도로 네트워크를 실행하기 위해 기존 연구들에 비디오 처리의 관점을 접목했다. 여러 프레임을 묶어 옵티컬 플로우를 생성하고, 첫 번째 프레임을 인스턴스 세그멘테이션한 후 마스크를 추출했다. 이후 마스크 영역만 뽑아낸 이미지를 새로운 입력으로 하여 스타일 트랜스퍼를 거치고, 이 첫번째 프레임과 나머지 프레임들의 옵티컬 플로우로 나머지 프레임들의 세그멘테이션과 스타일 트랜스퍼를 예측하여 다시 비디오 프레임으로 만들어 주었다. 본 알고리즘은 옵티컬 플로우 설정으로 네트워크의 계산량을 줄이며 속도를 개선했다. 빠른 데이터 처리로 사용자가 원하는 물체의 텍스쳐가 바뀔 수 있게 되었고, 이는 현실 세계가 실제로 바뀐 듯한 느낌을 들게 한다. 또한, 컴퓨터 비전에서 활발하게 연구되었던 분야를 AR로 끌어와 두 분야의 융합 가능성을 열었다. 현재 코로나의 영향으로 집에서 취미생활을 즐기는 인구가 많아졌다. 본 연구를 통해 많은 사람에게 집에서 쉽게 명화의 감성을 즐기고 느낄 수 있는 양질의 콘텐츠를 제공해주려 한다. 또한, 박물관과 미술관 등의 기관에서도 이 기술이 활용될 수 있다. 명화를 느낄 수 있는 다양한 콘텐츠를 이용하여 박물관이나 미술관의 홍보 효과도 기대할 수 있다.

The subway is one of the representative urban public transportation systems. Since its being opened in 1974, the Seoul Subway has been continually extended, and new lines are being added in the metropolitan and outskirt areas, even at present. As a result, the numbers of transfer stations and transfer sections have been significantly increased, making the usage of the subway system more and more complicated. In the transfer stations with big floating population and overlapped flows of traffic in the subway, passengers want their movements to be more precise and faster, without taking the wrong trains by mistake. Therefore, the visual information system for the subway inside the stations is extremely important. At the same time, the visual information system is required to be easy to understand and use, even if the passengers do not have previous experience of using the subway. In this research we studied the problems existing in the visual information system which is currently working in the subway system, and suggest the direction of the improvement of the subway service based on our studies. This research was mainly performed at Sindorim Station, one of the busiest stations in Seoul Subway with huge floating population and complex transfer sections. The purpose of this research is the investigation of behavioral and recognitive characteristics of passengers in the transfer sections through preceding research and qualitative analysis, to draw the direction for future improvement of the current system and suggest the improved experience of using the subway system.

Demographic changes such as an aging and low fertility, as well as changes in industrial structure and residential environment, revealed the limitations of urban development policies. Accordingly, the government is making efforts to ensure a prosperous life for the people by including the plan to expand the living SOC in the national urban regeneration policy. The main priority tasks of the Living SOC include the establishment of welfare infrastructure for children and the vulnerable. This means that interest in welfare is increasing recently. In this study, we analyzed the supply status of welfare facilities for the senior, child and the disabled in 17 cities and provinces nationwide using LQ (Location Quotient). After analyzing the causes of the imbalance in the supply of welfare facilities by region, the improvement plan was suggested. Each welfare facility was highly localized by region, especially the accessibility gap between cities and provinces is very large. Welfare finances were similar in most cities and provinces, with the exception of some cities and provinces. In the case of cities with very high living standards, sufficient facilities were not provided. Improvement methods are as follows; Combination of welfare facilities that can maximize space efficiency, Securing appropriate welfare finance in consideration of living standards by city and province, Differentiation of supply method considering demand and user types for welfare facilities.

In this research, to identify the degree of preference and participation in leisure sports, over 19-year-old adults living in the capital region were collected as subjects, and among them, 250 persons were chosen by sampling. Using SPSSWIN 16.0, I analyzed the collected data by Reliability Analysis, Paired Sample T-Test, and IP A method. The conclusion is the following. First, the first quadrant showed skins-cuba, water-ski, wind surfing, and clay-pigeon shooting, and as a result of this, it is necessary to improve the degree of participation in this field. Secondly, the second quadrant showed golf, snow board, ski, fishing, and climbing, and these field need to specific attention to maintain continuous attention, for they have a great deal of attendance. Thirdly, in the third quadrant, there are water sleigh, cart, balloon, sky-diving, orienteering, hang gliding, model plane, and survival game. As the degree of preference and participation in these sports is low, it is recommended that more effort should be made for these sports. Finally, in the forth quadrant, there are tracking, mountain bike, inline skates, rafting, and cycling. As it's the participation is high, while that of preference is low, it is important to maintain the policy of the participation in leisure sports. In conclusion, for the sports which is preferred that is difficult to join right now, most of all, it is necessary that we should pay attention to and invest the social infrastructure in which main items cannot be joined now.
