본고의 목적은 전 세계 무슬림의 약 90%에 해당하는 순니 무슬림의 3대 신학파(무타질라, 아샤리, 그리고 살라피)에 관해 분석하고 선교적 제안을 하는 것이다. 무슬림들은 무함마드의 사후에 내부적인 갈등과 정복전쟁으로 인해 외부에서 유입되는 헬라사상에 대면하여 이슬람을 종교적이고 논리적으로 방어할 필요성을 느끼게 되었다. 무타질라 학파는 신학적 탐구의 방법으로 철저히 이성을 사용하여 외래의 학문과 사상에 대응하면서 이슬람 교리를 옹호하였다. 아샤리 학파는 무타질라 학파보다 이슬람 전통에 더 비중을 두면서 꾸란을 창조물이 아닌 신의 본질로 이해하고, 인간의 자유의지보다 신의 섭리를 강조하며, 인과관계(causality)에 의한 종말론을 거부한다. 살라피 학파는 꾸란과 하디스의 내용을 문자적으로 받아들이고 이슬람 초기 시대의 살라프(선조) 들이 남긴 관행을 그대로 추종한다. 무슬림들에게 그리스도의 사랑을 증거하기 원한다면 이슬람의 다양성을 이해해야 하고 이슬람 신학의 중심에 위치하는 꾸란에 대한 성숙한 접근이 필요하다.

In order for the probe to perform ocean exploration and survey research, it is necessary to adjust the position of the ship as desired by dynamic positioning system. The dynamic positioning system of T/S NARA is applied to K-POS dynamic positioning system of Kongsberg, which makes maintaining the ship's position, changing position and heading control possible. T/S NARA is not capable of dynamic positioning if one or more propulsive forces are lost with DP Level One. However, it is predicted that dynamic positioning can be achieved even at the time of missing one thrust in a good sea condition. Therefore, we want to analyze the effect of each propulsion on the performance of dynamic position system. When one of the bow thruster and azimuth thrusters lost their propulsion, maintaining the ship's position, changing position and heading control performance were compared and analyzed. If the situation occurred disable from using the bow thruster, they can not maintain ship's position. Azimuth thruster was influential for the ship's position control and bow thruster was influential in heading control. The excellent dynamic positioning performance can be achieved, considering the propulsion power that will have a impact on each situation in the future.

This study aimed to analyze the profitability and economic feasibility of hairtail trolling line gear that was developed for the last 3 years (2015-2017). The new fishing gear technology development was accomplished to solve the current problem of fishermen shortage in hairtail targeting fisheries in Jeju region. Results indicated that the profitability of developed hairtail trolling line fishery was estimated to be 36.1 % which would be higher than that of other hairtail targeting fisheries in Jeju region. In addition, as an economic feasibility, the net present value and the internal rate of return of a 20-year cash inflow and outflow were evaluated to be 400.2 million won and 66.9 %, respectively. However, sensitivity analyses of main variables showed that the profitability and economic feasibility would be vulnerable to catch amount and market condition changes.
