In the past 20 years, passenger and cargo transportation performance at the international passenger ports in Korea have increased by 8.6% on the compound annual growth rate, respectively. The Korean government had expected to continue expanding the market of car ferries and the government included plans for the development of additional routes and lanes with neighboring countries such as China, J apan, and Russia as a part of the Plan of the Korean Ministry of Oceans and Fisheries in 2019. However, compared to the development of routes, the management and operation of passenger terminals are inefficient. The purpose of this paper was to introduce the overall improvement of the passenger terminal operating system that reflects the recent changes in the supply and demand of international passenger vessels and the needs of the government and private sector passengers. To this end, a basic survey was conducted on the status of operations and facilities at the Busan International P assenger Terminal and a questionnaire survey was administered on the subject of use. The results of the survey were analyzed using the IPA model. As a result of the analysis, three items in the operation sector, three items in the facility sector, and four items in the system sector of the Busan International Passenger Terminal were identified as in need of improvement. Based on the results, the need for investment to improve the international passenger terminal operating system is suggested.

Purpose: This study was done to examine the awareness and management practice of operating room nurses, to prevent nosocomial infection, to identify problems and to propose solutions. Method: The research tools used were the hospital infection control guideline and a modified version of the measurment tools used in the study of Cho (1998). The questionnaire consisted of questions on hand washing, personal hygiene and clothes control, cleaning and environment control, sterilizing supplies and disposal of contaminated materials. The collected data were analysed with the SPSS program. Results: The mean score for domain-specific awareness of nosocomial infection control was 4.81 out of a possible 5 points. The highest score was for sterilizing supplies and disposal of contaminated materials. The mean score for domain-specific practices of nosocomial infection control was 4.40, out of a possible 5 points. Sterilizing supplies and disposal of contaminated materials had the highest scores. The mean score for awareness in all domains was higher than mean score for practice. Among the general characteristics of the nurses, high awareness was found only in the provision of infection control guidelines and it had shown statistically significant difference. Examination of relation of general characteristics to practice showed that for age, career, the provision of infection control guidelines, and experience in infection control education there were statistically significant differences in the scores. For the relation between awareness of nosocomial infection control and practice, positive correlation was found in all domains, thus high awareness leads to high practice. Conclusion: Considering the result of this research, plans are needed that promote virtual practice of hospital infection control.

There are a lot of different types of noise from construction site and it depends on construction stage, equipment type and number of operating equipments. The problem is that the almost noise from construction site is high level and some kinds of noise levels are over 100 dB. In addition, if construction site is located in downtown, there are a few options to reduce noise level. Therefore several site mitigation plans were developed to reduce different types of construction noises such as breaker work, gang form and asphalt saw. They were applied in site and evaluated noise reduction performance. The test result of site insertion loss was between 4~8 dB depends on the equipment and type of work.

One of main concerns of operators of the Earth observation satellite is taking images as many as possible under the constraints of satellite resources during fixed period. In order to achieve this goal, satellite operators are strongly required to generate the optimized image collection plans, and it is a very time consuming process to achieve an optimized image collection plan when it is done by manual. This paper suggests automation of image collection planning based on the dynamic programming algorithm to reduce the time required for image collection planning. The validity of the proposed method is tested using operating satellite system and the result is given in this paper.

The sequential sampling inspection method is an extension of the double-sampling and multiple-sampling methods and its theory is based on the sequential probability ratio test(SPRT). In this paper, the characteristics of SPRT for testing the propotion of defectives are approximated by using the estimated excess over the boundaries. The use of the estimated excess shows good performances in estimating the operating characteristic function and the average sample number of SPRT compared to the method by neglecting the excess. It also makes it possible to determine the boundary values which satisfy the desired error probabilities.
