In order to overcome these problems, various accident response systems have been developed overseas and applied to ships and large cruise vessels. Recently, problems with the accident response system for the ship accidents have been pointed out. In Korea, the Emergency Response Service(ERS) operates to support urgent countermeasures to minimize damage in case of marine accidents. Usually it is necessary to deal with accidents within the first few minutes. However, if there is a problem responding to an actual accident, critical response time is lost. Because calling on an expert and analysing a blueprint are too time consuming, another approach is required. Therefore we have designed and implemented the Position Identification Module for locating lost crew members on ships that can overcome many of the disadvantages of the existing accident response system. The system which can identify the position of crew members in the ship is designed to be implemented as a module unit. It works to identify the location of crew members in the ship through two separate modules. The first one is called the โ€œPosition identification Module by Zoneโ€ that divides the ship into boundaries by considering the structure of the ship and the identification of boundary zones. The second one is called the โ€œPosition Identification Module In Zoneโ€ that is capable of identifying the position inside the module itself. In the design of the Position Identification Module By Zone, it works by defining the boundary area using a 900ใŽ’ RF-ID Reader and Tag. The module was designed so that it can process the per-zone data through installing the RF-ID Reader in the boundary zone. In the design of Position Identification Module In Zone, it can find the magnitude of energy, SVM(Signal Vector Magnitude), and measure the moving distance. This is done according to the size of the energy measured on a three-axis acceleration(Roll, Pitch, Yaw) sensor in MEMS sensor to find the position of any moving crew members in the main boundary zone. Additionally, it is also possible to recognize the direction of movement using a Gyroscope inertial sensor. In the case of SVM using the MEMS sensor, the data is processed to compensate for the moving distance of the energy magnitude according to the moving average method which continuously averages the magnitudes of energy and the moving averages. The processed data is then wirelessly shared using a fixed UHF communication modem. Implementing this in the module, the Position Identification Module In Zone is miniaturized and the Position Identification Data in Zone is shared by making it the crew membersโ€™ portable in an accident situation.1. ์„œ ๋ก  1 2. ์œ„์น˜์‹๋ณ„ ๊ด€๋ จ ๊ธฐ์ˆ  2.1 ์œ„์น˜์‹๋ณ„์˜ ํ•„์š”์„ฑ 3 2.2 RFID 4 2.3 ๊ด€์„ฑ ์„ผ์„œ 7 2.4 I2C, SPI ํ†ต์‹  9 2.5 Serial ํ†ต์‹  11 2.6 TCP/IP ํ†ต์‹  14 3. ์œ„์น˜์‹๋ณ„ ๋ชจ๋“ˆ ์„ค๊ณ„ 3.1 ๊ตฌ์—ญ๋ณ„ ์œ„์น˜์‹๋ณ„ ๋ชจ๋“ˆ ์„ค๊ณ„ 17 3.2 ๊ตฌ์—ญ ๋‚ด ์œ„์น˜์‹๋ณ„ ๋ชจ๋“ˆ ์„ค๊ณ„ 20 3.3 ์œ„์น˜์‹๋ณ„ ๋ฐ์ดํ„ฐ ํ†ต์‹  ๋ชจ๋“ˆ ์„ค๊ณ„ 23 4. ์œ„์น˜์‹๋ณ„ ๋ชจ๋“ˆ ๊ตฌํ˜„ 4.1 ๊ตฌ์—ญ๋ณ„ ์œ„์น˜์‹๋ณ„ ๋ชจ๋“ˆ ๊ตฌํ˜„ 26 4.2 ๊ตฌ์—ญ ๋‚ด ์œ„์น˜์‹๋ณ„ ๋ชจ๋“ˆ ๊ตฌํ˜„ 31 4.3 ์œ„์น˜์‹๋ณ„ ๋ฐ์ดํ„ฐ ํ†ต์‹  ๋ชจ๋“ˆ ๊ตฌํ˜„ 34 5. ์‹œํ—˜ ๋ฐ ์„ฑ๋Šฅ ํ‰๊ฐ€ 5.1 ์‹œํ—˜ ๋ฐฉ๋ฒ• 39 5.2 ์‹œํ—˜ ๊ฒฐ๊ณผ 39 5.3 UI๋ฅผ ์‚ฌ์šฉํ•œ ์„ ๋‚ด ์Šน์กฐ์› ์œ„์น˜์‹๋ณ„ ๋ฐ์ดํ„ฐ ์ฒ˜๋ฆฌ 44 6. ๊ฒฐ๋ก  47 ์ฐธ๊ณ ๋ฌธํ—Œ 49 ๋ถ€๋ก 51Maste

Main conclusions from a selective review of this research literature are as follows. First, the North Korean economy has shown a gradual recovery since the late 1990s. While the assessment of growth performance varies considerably among researchers, there is consensus on the fact that North Korea has yet to move beyond the low-income status. Second, as markets and the private sector developed, a dual structure in which the state sector and the private sector, plans and markets coexist, was formed. Third, reconstruction and reform of the state-run sector may also have contributed to the economic recovery to some extent. Fourth, North Koreas external economic relations, especially North Koreas trade with China have greatly expanded and have been of great help to both the private and the state-owned sector. The negative impact of international sanctions on North Korean economy is expected to become more serious as time goes by. Efforts to obtain richer and more accurate data are of primary importance for future research. When it comes to major policy tasks such as reform and opening of North Korean economy and inter-Korean economic cooperation, comparative research with former socialist countries or low-income developing countries could give useful implications
