한승훈,김홍렬,Han, Seung-Hun,Kim, Hong-Ryel 해양환경안전학회 2014 해양환경안전학회지 Vol.20 No.6
본 연구에서는 목포해양대학교의 실습선 새누리호를 대상으로 선박의 중앙집중 공조시스템에 공랭식 에어컨을 직접 설치하여 성능을 개선시킨 공기조화시스템으로 운전하였을 경우의 냉방 성능을 비교하고, 선실의 온열환경에 대한 실측조사를 통해서 향후 선박용 공기조화 설계 및 계획에 경험적 기초참고자료로 활용하고자 하는 것이다. 연구결과 동일한 외기조건에서 기존의 중앙집중방식 공조시스템과 개선된 공조시스템으로 운전하였을 경우, 모든 선실의 온도는 $24{\sim}28^{\circ}C$, 습도는 55~75 %로 쾌적한 조건임을 알 수 있었고, 발전기 부하를 측정결과 공기조화시스템의 성능개선에 따라 평균 부하 48 KW, 전부하시 부하율 약 8 %정도 감소하여 1일 연료소모량 FOC는 하루 평균 222[L/day]의 기름이 절약됨을 알 수 있었다. 또한 학생 선실(Cadet No. 21)은 기관실의 전열로 인해서 온도가 높게 나타났는데, 이것은 공기조화 설계 시 취출구 개수 및 전열부하를 고려하지 못한 결과로 판단된다. In this study, Mokpo national maritime university Training ship Centralizes Air Conditioning System was upgraded by installing onboard an Air-cooled Air conditioner. This resulted in the improvement of the performance and operation. This study compared refrigeration performance to former equipment and improving one. And through the actual measurement study about the cabin thermal environment, it will be used as basic data for marine air conditioning design and plan in the future. At same climate condition, when the Centralized Air Conditioning System and an improved air conditioning system operated, cabin temperature was at $24{\sim}28^{\circ}C$, humidity was 55~75 % as comfortable condition, Generator load measurement showed a saving of 48KW in the average load and 8 % in the full load factor. This also resulted in a saving of daily fuel oil consumption(FOC) at around 222 [${\ell}/day$] average. On the other hand, one cadet cabin(Cadet No.21) indicated a higher temperature due to heat transmission of engine room. It found us not to consider installing additional diffuser to reduce the heat transmission.

가상시험장은 양질의 시험 서비스를 보다 적은 비용으로 신속하게 제공하면서 실제 시험시에 발생할 수 있는 새로운 시험공간의 확보, 안전문제, 오염방지, 민원등에 효과적으로 대처할 수 있는 기술로 판단된다. 가상시험장의 효용가치는 가상시험 결과와 실제시험 결과의 근접성에 의해 결정되므로 모델링과 시뮬레이션 기술 개발과 더불어 Ground Truth Data의 축적이 선행되어야 성공적인 가상시험장 구축을 기대할 수 있다.

Semi-submersible drilling rigs are offshore plants that perform functions such as ocean exploration for oil and gas acquisition, drilling and production, and storage and unloading of crude oil and gas. Semi-submersible drilling rigs use watertight dampers as emergency buoyancy holders. Since the watertight damper is an emergency shutoff device, it is mainly driven by a pneumatic driving system that can operate without a power supply. The pneumatic driving system has highly non-linear characteristics due to compressibility of air and external disturbance such as static and Coulomb friction. In this paper, a new control algorithm is proposed for a watertight damper driving system based on the sliding mode control with a disturbance observer. To evaluate control performance and robust stability of the designed controller, the control results were compared with the results obtained using the state feedback controller. As a result, it was confirmed that the pneumatic driving system for driving the watertight damper using the sliding mode controller with a disturbance observer can obtain excellent control performance against the parameter changes and the disturbance input.

The risk of facilities in catenary is increasing because the railway section extension and high-speed train service. And visual check of workforce is not enough time to maintain the extensive railway facilities. Accordingly, The technical development trend of maintenance of railway facilities can be seen by automation and application of IT technology, especially the mechanization work and the information technology are spreading in the maintenance work of the train line solved by manpower. In this paper, we describe the method by obtaining the cantilever image using acquisition device and pole inspection system in high speed vehicle, to check the variation of the cantilever component using image processing.

The prophecy of jinin 眞人`s appearance was a wide-spread myth in the late Joseon Korea. Jinin was a messianic figure who was appointed to fulfil a prophecy to collapse the Yi dynasty in the near future. The participants in rebellion against government and the members of popular religious movements had taken jinin as their symbolic leader. This paper discusses the meaning and character of the myth by focussing on its awareness of place and space. It was related to the political feng shui 風 水concept ‘the energy of regal power(wang gi 王氣).’ The capital city was regarded as the place in where the energy was indwelling. The apocalyptic thought in premodern Korea asserted that the energy would be exhausted, and the founder of the new dynasty would take possession of the other place where had abundant energy. The books of prophecy(dochambigi 圖讖 秘記) popularized the myth, and it formed a eschatological mentality after 17-18th centuries. The latter half of the paper analyses several types of cases of rebellions and religious movements which the prophecy was magnified. The paper concludes that there were two cognitive maps in the culture of late Joseon period. While the official mapping of the state sacralized the capital city and royal authority, the revolutionary mapping of the rebels denied the dominant topography and suggested various spatial strategies.

본 연구는 우리의 서예교육이 지난 한 세기 동안 근대적 교육제도 속에서 주로 ‘조형미’를 중심으로 연구되고 교육되어왔다는 반성에서부터 출발한다. 서예는 ’실용’,‘ 예술’ ,‘인격수양’의 을 포괄하는 독특한 특정을 지닌다. 그럼에도 불구 하고 근대적 미술개념인 ’조형성에 초점이 맞추어져 교육이 이루어지다보니‘ 서예에 내재해 있는 ’인격미’ 가 간과되어 온 것이 사실이다. 또한 현재 우리 사회와 교육현장에서 인성교육이 미흡한 실정을 감안해 볼 때‘ 이러한 문제의식을 기초로 수양론을 대표하는 서여기인론(書如其人論)’을 고찰하고, 이를 통해 서예가 지니는 인성교육적 가치를 재조명하는 일은 의미가 있을 것이다. ‘서여기인’ 은 서예작품의 창작과 감상에 있어 창작주체의 인품을 함께 논하는 인식구조를 기반으로 한다. 즉 ‘조형미’와 함께 ‘인격미’를 강조한다. 또한 이러한 서예의 가치 인식을 기반으로 하여 서예학습 자체에 내재해 있는 정의적 요소를 살펴본다면, 중화미(中和美)의 체득을 통한 감정의 절제, 몰입을 통한 자기정화의 효과, 서제(書題)의 교훈을 통한 자아성찰 건전한 여가문화의 활용 등을 생각해 볼 수 있을 것이다. This study of our calligraphy education will begin with the reflection of our experiences with 'formative beauty' which is the center of our modern educational system for the past century. The structure of calligraphy is essentially established upon 'practical use', 'Art', and 'Personality Cultivation'. Despite having applied 'formativeness', a concept of modern art, into our education system, 'Personality Beauty', which is an inherent part of calligraphy has been allowed to be overlooked. In addition, by considering the insufficient consideration given upon the education of character in our society and educational system. and examining Seo-Yeo-Gi-In theory, which is a cultivation theory representing the basis of our awareness of these issues, it will be meaningful to refocus the values of education of character. which is through calligraphy. 'Seo-Yeo-Gi-In', this mean is consideried creator's personality when someone appreciate his or her work. Through 'Formative beauty', 'Character Beauty' will be emphasized, Also, by examining for affective elements in the learning of calligraphy itself. based upon calligraphy's values, we will be able to find the applications of emotional discipline through 'Harmony of beauty', self-purification through being immersed, self-reflection through calligraphy's titles. and healthy recreational cultures.
