    The International Maritime Organization referred to the reduction of carbon emissions of all ships with the strengthening of emission restriction on greenhouse gases and air pollutants(NOx, SOx, PM), set up a strong goal that reduce carbon emissions by 10% in 2015, and will continue to do that, on into the future. Today, to reduce those emissions, โ€˜green shipโ€™, such as hybrid or electric propulsion vessels powered by large batteries are being built. And therefore, it is necessary to manage batteries more strictly, because they have getting wider usages enough to be used as a power source for hybrid ship and electric propulsion ship. Hybrid ship has power supply units connected to the packets to produce more than 500kWh large power source, and therefore, A number of the communication modules and wires need to implement the wire inspection and monitor system that allows monitoring server to transmit detecting voltage, current and temperature data, which is required for the management of the batteries. This paper proposes a remote monitoring system of lithium batteries for green ship using BLE wireless communication modules and power line modem.1. ์„œ ๋ก  1.1 ์—ฐ๊ตฌ ๋ฐฐ๊ฒฝ ๋ฐ ํ•„์š”์„ฑ 1 1.2 ์‹œ์žฅํ˜„ํ™ฉ 3 1.3 ์—ฐ๊ตฌ ๋ชฉ์  6 2. ๊ด€๋ จ ์ด๋ก  2.1 ์—๋„ˆ์ง€ ์ €์žฅ์žฅ์น˜์˜ ์ข…๋ฅ˜ ๋ฐ ํŠน์„ฑ 7 2.2 BMS ์ด๋ก  13 2.2.1 C-rate 13 2.2.2 DOD 14 2.2.3 SOC 15 2.2.4 SOH 17 2.3 Bluetooth Low Energy 21 2.3.1 Bluetooth ํ†ต์‹  ๊ฐœ์š” 21 2.3.2 ๋ธ”๋ฃจํˆฌ์Šค ํŒจํ‚ท ๊ตฌ์กฐ 25 2.3.3 BLE Advertising mode 26 2.4 PLC 28 3. ๋ฐฐํ„ฐ๋ฆฌ ์›๊ฒฉ๊ด€๋ฆฌ์‹œ์Šคํ…œ ๊ตฌ์„ฑ 3.1 ํ•˜๋“œ์›จ์–ด 30 3.1.1 BMS ๊ตฌ์„ฑ 31 3.1.2 ํ•˜๋“œ์›จ์–ด ์„ค๊ณ„ 33 3.2 ์†Œํ”„ํŠธ์›จ์–ด ๊ตฌ์„ฑ 39 3.2.1 BMS ๋ชจ๋‹ˆํ„ฐ๋ง ์†Œํ”„ํŠธ์›จ์–ด 39 3.2.2 BMS ๋‚ด๋ถ€ ์†Œํ”„ํŠธ์›จ์–ด ์ˆœ์„œ๋„ 41 3.2.3 ๋ฐฐํ„ฐ๋ฆฌ์˜ ์ด๋ก ์  ์ˆ˜๋ช… ๊ณ„์‚ฐ 44 3.2.4 ์˜จ๋„ ํšŒ๋กœ ๋ณด์ •๊ฐ’ 45 3.3 ์‹คํ—˜ ๋ฐ ๊ฒฐ๊ณผ ๊ณ ์ฐฐ 47 3.3.2 ๋ฐฐํ„ฐ๋ฆฌ ์ด๋ก  ๋ฐ ์‹คํ—˜ ์ˆ˜๋ช… ์˜ˆ์ธก 51 3.3.3 ๋ฐฐํ„ฐ๋ฆฌ OCV ๋ฐ SOH ์ธก์ •์— ์˜ํ•œ ์ž”์กด์šฉ๋Ÿ‰ ๊ณ„์‚ฐ 53 3.3.4 ์ „๋ ฅ์„  ๋ฐ BLE ํ†ต์‹  ์‹คํ—˜ 56 4. ๊ฒฐ๋ก  60 ๊ฐ์‚ฌ์˜ ๊ธ€ 62 ์ฐธ๊ณ ๋ฌธํ—Œ 6

Nevertheless, Korean society has witnessed a sharp rise in social conflict in recent years and Koreans find it difficult to make a social consensus about how society can manage such conflicts. This paper looks into the social basis of such conflicts in Korea in order to understand the nature of social conflict and to find desirable and feasible paths to social integration. The social basis of conflicts is divided in the paper into three main components: social norms, social needs and economic interest. Such a social basis influences stakeholders to take positions on public issues, and the competing positions of different stakeholders often lead to social conflicts. The paper examines the social basis of conflicts within this framework. This paper first examines social norms and structural and demographic changes including the dual labor market. The paper secondly discusses labor market reform and the universal provision of welfare that has been proposed to tackle social conflict. The paper argues that those policy proposals need to be revised in order to achieve fair and equitable compromises. Thirdly, the paper argues that Korean society should strive for a political community that allows differences to co-exist, a community in which individuals can collaborate together with trust

The aim of this paper is to suggest Korea`s policy toward fragile states which pose great challenges for global poverty reduction. This paper, first, constructs profiles of the fragile states by paying attention to three essential dimensions of state fragility: politics, public administration and security. Using multiple data sets, this paper identifies 18 fragile states which appear at least once in the top ten lists of each fragility dimension. Although the profiles of fragility are different among these fragile states, Afghanistan, Somalia, Sudan and Democratic Republic of Congo are identified as the highly fragile states, being listed in all three dimensions of fragility. Secondly, this paper examines Korea`s international cooperation with the fragile states. Although Korea has provided development assistance to most fragile states, it lacks a clear policy framework and country-specific policies. This paper suggests that Korea should develop a three-pronged cooperation policy for the fragile states: preparing country-specific assistant strategies with emphasis on state-building assistance, taking a whole-of-government approach and taking advantage of Korea`s development experience.์ด ๋…ผ๋ฌธ์€ 2010ํ•™๋…„๋„ ์„œ์šธ๋Œ€ํ•™๊ต ํ•œ๊ตญํ–‰์ •์—ฐ๊ตฌ์†Œ์˜ ๊ธฐํš๋…ผ๋ฌธ์œผ๋กœ ์ง€์›์„ ๋ฐ›์•˜์Œ
