데이터방송 표준 관련해서 지난 2005년 8월에 미국 지상파 데이터방송 표준인 ATSC ACAP이 정식으로 통과되면서 우리나라의 지상파 데이터방송 표준도 2005년 9월에 ACAP 표준을 따르도록 새롭게 제정되었다. 따라서, 정통부와 방송사 그리고 관련 가전사들간에 지상파 데이터방송 본방송 일정에 관한 협의가 본격적으로 이뤄지는 계기가 마련되었다. 그러나, 지상파 데이터방송은 근본적으로 지상파 DTV 채널의 대역폭이 제한되어 있어서 다양한 데이터방송용 애플리케이션을 빠르게 전송하는 것이 사실상 불가능한 실정이다. 이에 본 논문은 오브젝트 캐로설 구성 시 ACAP 표준의 ACAP-X 프로파일에서 규정된 BIOPProfileBody 뿐만 아니라 HTTPProfileBody도 ACAP-J 프로파일에서 추가로 지원하도록 하여 실제 애플리케이션을 구성하고 있는 일부 혹은 전체 파일 오브젝트를 지상파 온에어 채널로 전송하는 대신 리턴채널을 이용하여 빠르게 전송하는 방법을 연구 ${\cdot}$ 개발하였다.

Since the specifications of public services in broadcasting-telecommunication convergence environment are not standardized, the public services should be developed and presented by each IPTV service provider, and therefore it is worried that public organizations and IPTV service providers may invest in the public services redundantly, which are managed inefficiently. To resolve those problem, in this paper, the service and network interfaces among multiple public organizations and multiple IPTV service providers and the interactive VOD-type public service providing system of one source multi-use based on ACAP-J are proposed. The proposed system can be utilized in the standard platform of the evolved new public services. And the used technologies can be utilized as a guide for the development of new services.

방송통신 융합 환경에서 공공서비스를 제공하기 위한 표준화나 규격정립이 안되어 있어 현 시점에서 대국민 서비스를 제공하기 위해서는 IPTV 사업자별로 별도의 IPTV 서비스 개발 및 제공이 필요하며, 이에 따른 중복투자 및 운영의 비효율성이 우려된다. IPTV기반 방통융합공공서비스를 제공함에 있어 공공기관과 IPTV사업자들의 중복투자를 막고 효율적인 서비스 제공을 위해 복수의 공공기관과 복수의 IPTV사업자간 효율적인 서비스연동 및 통신망 연동을 위한 체계 정립이 필요하다. 또한 One Source Multi-use 구현을 위한 ACAP-J기반의 서비스 표준플랫폼 정립을 통한 상호 연계 방안 확립이 요구된다. 이에 본 논문에서는 ACAP-J기반의 One Source Multi-use를 위한 양방향VOD형 공공서비스 제공 방안과 관련 규격을 제안한다.

Traditionally, like many people in mountain region of the Himalaya, the Lwang communities depend on mix of subsistence agriculture, animal husbandry, and seasonal migrant labor for their livelihoods. These traditional systems are characterized by low productivity, diverse use of available natural resources (largely for home consumption), limited markets, and some aversion for innovation. The potential to generate wealth through commerce has largely been untapped by these mountain residents and thus is undervalued in local and national economies. Introduction of organic tea farming is a part of Lwang community's several initiatives to break the vicious poverty cycle Annapurna Conservation Area Project (ACAP) played facilitating roles in all their efforts since beginning. In five years, the tea plantation emerged as a new means for secured a livelihood. This study aims to analyze the current practices in tea farming both in terms of farm management and soil nutrient status(technical) and the prosperity of the tea farmers (social). The technical aspect covers the soil and tea leaf analysis of various nutrients contents in the soil and tea leaf. Originally, the technical aspect of the study was not planned but later during the consultation with the advisor it was taken into consideration which added value to the research study. The sample were collected from different locations and analyzed on the field itself. The other part of the study i.e. the social aspect was done through questionnaire survey and focus group discussion. the tea farming provided them not only a new opportunity but also earned an identity in the region. This initiative was undertaken as a piloting measure. Now that the tea is in production with processing unit established locally, more serious consideration has to be given for better yield and economic prosperity. This research finding will help the community to analyze their efforts and make correction measures in tea garden management and application of fertilizer. It is also expected to fill up the gaps of knowledge and information required to reduce economic stresses and enhance capacity of farmers to make the tea farming a sustainable and beneficial business. The findings are expected to Sustainability of organic tea farming has direct impacts on biodiversity conservation compared to the other traditional farming practices that are more resource intensive. The study will also contribute to identify key action points required for reducing poverty while conserving environment and enhancing livelihoods
