In this study, deep learning model was set up to predict the wave heights inside a harbour. Various machine learning techniques were applied to the model in consideration of the transformation characteristics of offshore waves while propagating into the harbour. Pohang New Port was selected for model application, which had a serious problem of unloading due to swell and has lots of available wave data. Wave height, wave period, and wave direction at offshore sites and wave heights inside the harbour were used for the model input and output, respectively, and then the model was trained using deep learning method. By considering the correlation between the time series wave data of offshore and inside the harbour, the data set was separated into prevailing wave directions as a pre-processing method. As a result, It was confirmed that accuracy and stability of the model prediction are considerably increased.

비점원오염은 하천 및 지하수 수질오염에 많은 기여를 하고 있는 것으로 나타나고 있는 반면에 우리나라에서는 비점원오염에 관한 연구는 상대적으로 미약한 것으로 지적되고 있다. 본 기사에서는 비점원오염에 대한 이해를 증진하고 현장실험연구를 활성화하는 데 기여하기 위하여 미국 등의 선진국에서 실행하고 있는 현장실험방법을 경지단위의 연구, 유역단위의 연구, 그리고 지하수 수질에 관한 연구로 구분하여 고찰하였다. 비점원오염에 관한 현장연구방법, 연구시 중요사항, 고려하여야 할 사항 등에 관한 자료는 'Gale, J.A., D.

In this paper, Power Management System(PMS) simulator for Liquid Nature Gas Carrier(LNGC) is developed. Major components of power system for LNGC, such as generator, diesel engine and governor, transformer, circuit breaker, and 3 phase loads models are built based on MATLAB/SIMULINK. With these designed major parts, PMS simulator modeling is carried out. Based on MATLAB/Graphical User Interface, PMS simulator control for LNGC, and Human Machine Interface for monitoring is designed. PMS simulator for LNGC carries out simulation according to sequence of characteristics analysis. By comparing results of predicted simulation for each sequence to that of characteristics analysis, the reliability of PMS simulator for LNGC will be verified.

자동차를 멈출 수 있게 하는 제동장치, 원하는 방향으로 운전할 수 있도록 하는 조항장치, 노면으로부터 전해지는 충격을 최소화해주는 완충장치는 엔진과 함께 자동차에서 가장 중심이 되는 부품이며, 탑승객의 생명을 지켜주고 안락한 승차감을 제공하는 장치들이다. 이런 중요한 부품들을 제조 생산하는 국내 대표기업에는 (주)만도가 있다. (주)만도가 주저 없이 '국내 대표기업'이라는 명성을 얻게 된 이유는 지난해 약 6조 원의 매출액을 기록하는 등 한국 자동차부품업계의 선두 자리를 놓지 않고 있기 때문이다. 국내 자동차 부품업계 굴지의 기업, (주)만도의 R&D센터에서 안전관리를 다망하고 있는 안광식 과장이 오늘의 주인공이다. 안전이 곧 개인의 행복이며 기업의 경쟁력이라는 철학으로 근무하는 그를 만나 기업을 안심일터로 이끄는 비법을 들어봤다.

We suggested the policy of labor management in pump manufacturing industry through survey in order to improve competitive ability. In pump manufacturing industry, since it is difficult to find sufficient worker having technical skill and knowledge concerning pump manufacturing technology, therefore the industry must cultivate the employee systematically. We reached the result, production engineer and R&D engineer play an important role to improve competitive ability in pump manufacturing industry. Though they need technical education, the effect of education was not satisfactory. To solve this problem, suitable technical education course must be devised. Marketing reinforcement is a important factor in pump manufacturing industry. To achieve marketing reinforcement, each company must develop their present technology further and raise marketing ability to expand internal and external business. It is also consulted to use IT technology.

Antenna Tracking System has been required core technology with special tracking algorithm, and it can be achieved by program tracking, step tracking, optracking, and monopulse tracking as well. Depend on tracking requirement we might be able to apply eligible tracking method in accordance with Geostationary and Inclined Orbit Satellite. Further, we should deeply consider two important factors in order to act up to customer expectation in quality and system performance including competitive price therefore we need maximized endeavor to upgrade not only tracking system performance, but reduction of product through engineering skill and R&D investment.
