본 연구는 김정은의 권략강화와 독자노선의 제도화과정을 분석하기 위해 김정 은의 유훈통치와 세습정치과정, 헌법적 지위변동 추이와 ‘수령’의 지위 확보과정, 독자노선의 확립과정 등을 학술논문과 로동신문 등 관련문헌을 통하여 분석하였 다. 김정은의 권력은 개헌을 통해 헌법적 지위와 권한이 계속 상승되었는데 2019년 8월 새 헌법에서는 김일성(주석), 김정일(국방위원장)의 지위, 권한보다 우위를 점하였다. 북한에서 ‘수령’은 최고 존엄을 가리키는 대표적 상징이며 최고 수위를 나타내는 용어인데 2021년 1월 8차 당 대회에서 김정은을 수령으로 추대 하였으며 2022년 말부터 본격적으로 수령으로 지칭하고 있다. 또한 ‘사상의 영 재’라고 불리었던 김정은이 ‘사상의 천재’(김정일)를 넘어 ‘사상의 창시자’(김일성) 반열에 오르게 되었다. 2016년 제7차 당 대회에서 ‘당 위원장’이라는 새로운 직 함으로 추대된 김정은은 2022년 7월 ‘새 시대 당 건설 사상이론을 제시하였고 ‘새 시대 당건설 5대 노선’이라는 명칭으로 당의 정식노선으로 채택되었다. 김정 은의 선대영향력과 유훈통치의 탈피시도는 여전히 많은 도전을 받고 있다. 군의 반발과 갑작스러운 사회통제 메커니즘의 공백을 불러올 수도 있다. 북한은 우리 와 한민족이며 우리가 포용하고 통일을 이루어야 할 대상이다. 따라서 한국정부 는 김정은 정권의 독자노선 추구와 북한체제의 변화 가능성을 예측하고 분석하 여 남북관계를 발전시키고 나아가 통일에 접근할 수 있는 방안을 모색해야 한다.

This study has been conducted on the subjects of eight undergradu˗ ate students with abdominal obesity and eight undergraduate stu˗ dents with normal weight to find out correlation between substantial fatigue and Ratings of perceived exertion through analysis of their blood components when they took exercises to strengthen their abdominal muscular power. Comparatively analyzing HDL-C, LDL-C and lactic acid before and after they took sit-up at level of RPE 19-20, no statistically significant differences in HDL, LDL, lactic acid meas˗ ures were observed between groups, but a significant difference in RPE was noted between groups(p<0.05) Our findings suggest that control group showed no significant differ˗ ence in increase of fatigue material whereas the obese group showed a lower frequency of sit-up, though both groups took the same abdominal exercise. Additionally, the lower frequency of sit-up in obese group results from relatively higher Ratings of perceived exer˗ tion rather than increase of substantial fatigue material. This study invites future research that examines the effect of a comprehensive obesity exercise program combined with dietetic

Even if the amount of exhaust gas is the same, it is possible to reduce the exhaust gas exit heat at the outlet of the boiler facility by lowering the outlet temperature of the economizer, so that it is possible to increase the heat quantity recovered from the boiler facility. There are many cases where the existing facility adopts 220~250℃ as the design value of the exhaust gas temperature at the exit of the economizer. However, in recent years, there has been a case of cooling and recovering heat to 200℃ or less from the viewpoint of active heat recovery. The amount of combustion exhaust gas is reduced by reducing the amount of combustion air supplied to the incinerator, and the amount of heat exhausted from the boiler facility is reduced, thereby improving the boiler efficiency. The holding energy of the combustion exhaust gas is the product of the exhaust gas amount and the specific heat and the temperature. In order to recover more heat from the combustion exhaust gas, not only the heat loss in the boiler facility is reduced, but also the heat radiated from the boiler facility is reduced. It is effective to reduce the exhaust gas temperature at the outlet of the heat recovery equipment and reduce the amount of exhaust gas in order to reduce the amount of exhaust heat of the exhaust gas. Even if the exhaust gas temperature at the outlet of the economizer is the same, the amount of exhaust gas discharged at the boiler facility outlet is reduced by reducing the amount of exhaust gas, and an increase in the recovered heat quantity at the boiler is expected.

The intensification of the competition among container terminals has led to important affect such as, decision making or aggressive intervention of customers for terminal operation. Therefore, in case of developed ports, the large transition of port operation is composed of the press of terminal customer than decision making of terminal manager. Overall port tariffs for using terminal is made out by the conference of terminal customers than the supreme headquarters of terminal operation, and the related investment of terminal has been made according to requisition or proposal of customers. Therefore, among decision making problems that shippers, shipping companies, and freight forwarder among decision making problems that shippers, shipping companies, and freight forwarder face, the choice of the container terminal is one of the most important problems. So, the decision making of the users seems to have a significant impact on the competitive power of container terminals. The main objective of this study is to design port marketing strategy for strengthening the competitive power of container terminals. The results of this study were found as follows: Firstly, port authority should establish user-oriented operation policy of terminal as the means of activating the opinion window, using terminal monitoring system(TMS). Secondly, terminal planning and development of government should be made to minimize the lead time, to induce the civil capital and to utilize the economies of scale. Thirdly, port authority needs to endeavor to analyze the information of competing foreign terminals as well to promote the concentrated marketing for the terminal on the users, to train the expert and to develop the new port charge system. Fourthly, to improve the competitive power of the container terminal, Port Authority should optimize the subsystems related to port marketing, far more these systems should be joined organically to work effectively. Finally, port authority system should be introduced, Namely, port should have the enterprise inclination as well s the public inclination.
