In this study noise source in a ward at four general hospitals in Seoul area has been investigated and analysed. The degree of reaction against noise by 171 randomly has also been examined. The results of the study have shown that the source of noise is the speakers of wired broadcasting or from visiting guests in two hospitals located in residential area. The patients at the two other hospitals located at commercial site have been suffered more from traffic noise. However, because of their separated living at hospital from their ordinary houselife, sixty one percent of the inpatients have wished a music sound of around 60 dB (A). After having considered the results of the investigation and wishes of the inpatients, following suggestions have been made: 1. Reduce the number of guests or their length of stay. 2. Wired broadcasting system should be substitued by wireless one, or if it's unavoidable, it should be used in office rooms only. 3. Since the stops and starts of vehicles induce much noise, Seoul City Government be requested to prepare an appropriate administrative measure for the vehicles around hospital area and it should prevent the establishment of new hospitals along high way site. 4. By using earphone, inpatients can choose a wireless channel according to each individual's taste. This through the masking effect, would cover up the noise source. 5. Rooms along the streets should be utilized as offices, otherwise double windows should be set up for inpatient's wards.

Social distancing caused a sharp industrial stagnation in the performance industry. Due to the continuous industrial downturn, as well as the livelihoods of many related workers, the outlook for the performance industry has reached a point where it is impossible to foresee the future. As a result of seeking various ways to recover from the continuing industrial stagnation, online concerts drew attention as the most effective alternative. Its development potential was highly evaluated as it could provide a performance culture to consumers while complying with social distancing. This study has value in terms of academic contribution as it slightly suggests a direction for the sustainable development of online performances presented as a breakthrough amid the social and industrial stagnation caused by the pandemic. therefore, this thesis describes the changes in the performance industry due to social distancing, and collects and analyzes examples of online performances by type to illuminate the value of online performances as an industry in the pandemic era and develops them. The possibility was reconsidered and the direction to be taken in the future was suggested. In each type of case, the cases focused on social value did not satisfy the economic value of profit creatiom, and even in the opposite case, if the profit creation was satisfied, the analysis result showed that the social value was not satisfied, and the planning intention of each performance was not satisfied. Accordingly, cases such as satisfying both profit creation and social value were also confirmed. Therefore, the direction for online performances was presented through the improvement of technologies and systems and the commercialization of existing platforms.

As the importance of Culture Technology (music, publication, mobile, film, video, cartoon, animation, character, game, broadcasting etc) is increased, the field of character industry recently has been recognized as an independent brand value beyond the existing view point of simple designing; it also has been given much attention as a main axis leading the cultural industry of the 21 st century. The character of a local government plays roles such as a symbolic part of a region, parts of tourism and public relations, and a profit-making function, which results into generation of regional image and activation of regional economy. However, the present application strategy of the character is only limited to an early stage of regional advertisements. In this context, this study is aimed to investigate and analyze the character development of local governments, especially 31 cities and goons of Gyeonggi Province, comparing with those of local governments of Japan. In the long run, this will provide some suggestions for strategy of character applications. Then, this research is expected to be used as basic reference materials for character development of other local governments and government agencies.

현재까지의 국가 정보화 정책은 초고속 국가망, 전자정부 시스템, 유비쿼터스 기술개발 및 산업현장 적용 등 정보화 기반 구축 및 서비스 촉진 중심으로 추진되어 왔다. 유 무선 통합, 전화 인터넷 게임 음악 등 단말의 융 복합, 통신과 방송의 경계 붕괴 등 새로운 기술 환경으로 빠르게 변화 하고 있으며, 전자정부, 인프라산업 등 국가 정보화와 관련된 정책간 시너지를 극대화 하기위한 정책 방향이 필요하다. 이러한 기술 발전과 초고속 멀티미디어 서비스 제공을 가능하게 기반을 제공한 것이 2000년 이후 급속적인 광케이블망 보급 확대와 2006년 하반기부터 FTTH에 대한 투자를 활발히 진행되어 왔기 때문이다. FTTH를 기반으로 하는 다양하고 고품질의 서비스 개발 확대와 지속적인 인프라 투자 증가에 따라 향후 모든 가입자 댁내까지 효율적인 FTTH 구축을 추진하기 위해 그동안 발생되어진 문제점들과 이를 해결하기 위한 대안을 제시 하고자 한다. 특히 FTTH 구축에 따른 국사내 시스템 상면배치 문제를 비롯하여 현재까지 RN(스플리터)의 지하 맨홀 내 광접속함 설치에서 전주 광단자함으로 배치이동에 대한 장점 등 가입자 수요 요구에 탄력적으로 대처하기 위한 경제적이고 지하 맨홀 내 광접속함 설치에서 전주 광단자함으로 배치이동에 대한 장점 등 가입자 수요 요구에 탄력적으로 대처하기 위한 경제적이고 효율적인 구축방법에 대해 분석하였다. 또한, 광단자함의 2차RN 스플리터를 설치하여 가입자를 개통하는 방법에 대한 문제점과 가입자 개통시 적용하는 현장조립커넥터에 대한 사용상의 불편함, 손실증가 문제, 가입자 개통구간 고장발생시의 대처방안 문제점 등에 대해 살펴보았으며, 다양한 가입자 주거 환경에 따른 댁내 망구성에 현재 까지 발생된 문제점과 이를 해결하기 위한 방법을 제시하고자 한다.

Asia has shown a tendency that a certain country's culture leads the fashion in turn every 10 years. The trend of Hong Kong movies in 1980's was called 'Hong Kong Wave', the trend of Japanese animation and games in 1990's was called 'Japanese Wave', and then the 'Korean Wave' began in the late 1990's. This term '~Wave(流)' is a Japanese-style term meaning '~way', '~style', '~group', and so on. In the same manner, recent popularity of Taiwanese TV dramas and a particular star that is in fashion in Japan are called 'Taiwanese Wave', and Chinese movies, broadcast, tourism, and etc. are called 'Chinese Wave'. Thus, the term 'Korean Wave' is a part of expression '~wave' used in Japan and it started to be used in the mean time, and was officially used in <韓流-Song from Korea>, a promotion record of Korean pop music, produced by Ministry of Culture and Tourism in Korea. In this paper I propose to correct the error of the term 'Korean Wave', and furthermore, to define a term expressing Korean culture and study for its usage.

광기록의 역사는 1980년대초 Sony와 Philips가 공동 개발한 CD (compact disc: 640MB)의 출현으로부터 시작하여 1996년의 DVD (digital versatile disc: 4.7GB)를 거쳐 최근의 BD (Blu-ray disc: >20GB)에까지 이르고 있다. Read-only memory, recordable, rewritable 등 다양한 저장 및 재생방식이 존재하는데, 이는 레이저 조사에 의한 기록매체의 특성변화의 가역성 (reversibility)에 의존하므로 저장 및 재생방식에 따라 저장매체 또한 다르게 된다. 기록용량의 증가는 레이저의 파장이 짧아지고 동시에 사용된 렌즈의 개구수 (NA: Numerical aperture)가 증가함에 따른 빔 spot size의 감소에 기인한다. 회절한계를 극복하여 빔의 spot size를 줄이고자 하는 연구는 현재도 전세계적으로 활발히 이루어지고 있고 이러한 노력의 일환으로 어느 정도의 추가적인 저장용량 증가는 가능할 수 있으나, 2차원 방식으로는 대용량 광정보기록 (수백 GB ${\sim}$ TB급)의 실현은 불가능하다는 것이 일반적인 예상이다. 한편 장기적으로 기존의 2차원 정보기록방식을 대체하고 저장용량을 획기적으로 증가시킬 수 있는 bit-type 3차원 광정보기록의 개념이 1990년을 전.후로 처음으로 제시되었다. 이는 2차원 bit 정보가 수십 내지 수백 개의 다층 (multi-layer) 형태로 기록되는 방식인데, 그동안 산업체의 관심이 상대적으로 높지 않았던 이유는 영화, 음악 등 엔터테인먼트 시장성 확대를 위해 Blu-ray disc나 HD-DVD에 대한 연구개발에 치중해왔기 때문이다. 하지만 최근 급변하는 정보시스템 서비스 환경 속에서 정보유통량이 기하급수적으로 증가하고 있고 개인이 취급하는 정보량도 2010년경에는 수백 GB 단위가 될 것으로 예상되고 있으며 디지털 방송, 네트워크를 기반으로 한 서비스 수요 뿐 만 아니라 전자도서관이나 VOD (Video on Demand) 서비스 사업에 필수적인 수 TB급의 대용량 저장장치에 대한 수요 또한 크게 증가할 것으로 전망된다. 이에 따라 점차 그 물리적 한계에 다다르고 있는 기존의2차원 정보저장방식을 대체하고 저장용량을 획기적으로 증가시킬 수 있는3차원 정보기록(> $10^{13}$ $bits/cm^3$)에 대한 필요성이 대두된다.
