  • Measures on poor process should be identified by reviewing analysis of planned progress and actual progress for successful performance of Process Control. However, the existing Process Control only performances follow-up measures on poor process but it cannot prevent poor process which is not occurred. To solve these problems, this study suggests the three types of methods of process prediction(Regression Analysis) by using a progress rate which consists of planned progress rate and Actual progress rate.

  • With the rapid development of China's industrialization and urbanization, air pollution has become a growing concern. The emergence of air pollution not only affects people's health, but also restricts the development of China's social economy. This paper puts forward specific measures for air pollution control by examining the causes of air pollution and by comparing air pollution status and management policies between Korea and China. Methods of control involve improving the urban environmental management mechanism, spreading awareness of urban environmental management and air pollution management laws and regulations system, strengthening clean energy utilization and urban environmental greening, increasing investment and management funds and more. Through these measures, urban environmental management in China can be accelerated and level of environmental management improved.

  • The 62nd session of the MARINE Environment Protection Committee was held in London from 11 to 15 July 2011. Mandatory measures to reduce emissions of greenhouse gases (GHGs) from international shipping were adopted at the Committee. The amendment to MARPOL Annex VI includes a new chapter 4 to make mandatory the Energy Efficiency Design Index (EEDI) for new ships and the Ship Energy Efficiency Management Plan (SEEMP) for all ships. This first mandatory measures on energy efficiency will enter into force on 1 January 2013. This amendment to MARPOL Annex VI will significantly influences the vast majority of the international maritime community. This paper mainly discusses the main results of MEPC 62nd session including the recent Emission Control Area.

  • Various methods of analysis have been proposed to understand the gene-disease relation and gene-gene interaction effect for a disease through comparison of genotype in case-control study. In this study, we proposed the method to detect a genetic association and gene-gene interaction through the use of a network graph and centrality measures that are used in social network analysis. The applicability of the proposed method was studied through an analysis of real genetic data.

  • In the first part of this paper, an analysis of the cab noise of a selected agricultural tractor was presented. In this study, using the results of the previous analysis, two passive noise control measures of the sound insulation and absorption were conducted to reduce the noise level inside the cab. These measures of noise control reduced the total noise level by 6.2㏈(A) at the operator position inside the cab. In order to further reduce the cab noise, particularly, of lower frequencies than 630Hz, stiffness and damping of the floor panel should be enforced. It was also suggested that a proper suspension for the cab mounting is necessary to reduce the level of structure-born noises.

  • In this paper, we consider a standby redundant structure with a function of switchover processing which may not be not perfect. The switchover processing is governed by a control module whose failure may cause the failure of the whole system. The parameters measuring such an effect of failure of the control module is included in our reliability model. We compute several reliability measures such as reliability function, failure rate, MTBF, mean residual life function, and the steady state availability. We also compare a single unit structure and the redundant structure with regard to those reliability measures. An example is given to illustrate our results.

  • A Safety Case is an railway organization's formal arrangement, through the provision of policies, resources and processes, to ensure the safety of its work activity within safety management system. An effective system helps the organization to identify and manage risks effectively. It allows an organization to demonstrate its capability in achieving its safety objectives and in meeting regulatory requirements. The purpose of this research is to give how to the risk assessments are described within Railway Safety Cases can be prepared and maintained to meet the criteria specified by the upcoming railway regulations. Through this research, we propose the elements of safety management system that include arrangements for the ongoing identification of hazards, assessment of risks and the implementation of necessary control measures.

  • The rapid increase in genetic dataset volume has demanded extensive adoption of biological knowledge to reduce the computational complexity, and the biological pathway is one well-known source of such knowledge. In this regard, we have introduced a novel statistical method that enables the pathway-based association study of large-scale genetic dataset-namely, PHARAOH. However, researcher-level application of the PHARAOH method has been limited by a lack of generally used file formats and the absence of various quality control options that are essential to practical analysis. In order to overcome these limitations, we introduce our integration of the PHARAOH method into our recently developed all-in-one workbench. The proposed new PHARAOH program not only supports various de facto standard genetic data formats but also provides many quality control measures and filters based on those measures. We expect that our updated PHARAOH provides advanced accessibility of the pathway-level analysis of large-scale genetic datasets to researchers.

  • African swine fever (ASF) is one of the most complex infectious swine diseases and the greatest concern to the pig industry owing to its high mortality and no effective vaccines available to prevent the disease. Since the first outbreak of ASF in pig farms, ASF has been identified in 14 pig farms in four cities/counties in South Korea. The outbreak was resolved in a short period because of the immediate control measures and cooperative efforts. This paper reviews the ASF outbreak and the experience of successfully stopping ASF in pig farms in South Korea through active responses to prevent the spread of ASF. In addition, suitable changes to build a sustainable pig production system and collaborative efforts to overcome the dangerous animal disease, such as ASF, are discussed.

  • Objective: This study aimed to assess the effectiveness of a balance training program in improving balance and functional independence to reduce fall risks among community-dwelling elders. Design: A multi-center randomized controlled trial Methods: A total of 66participants were randomly assigned to a balance training group or a control group. The balance training program, conducted three times a week for 32 weeks, included warm-up exercises, main balance training exercises, and cooldown stretch exercises. Outcome measures included the Berg Balance Scale (BBS), Timed Up and Go Test (TUGT), and Modified Barthel Index (MBI). Results: The balance training group demonstrated significant improvements in all outcome measures, indicating enhanced balance, improved functional mobility, and increased independence in activities of daily living. In contrast, the control group showed only slight improvements in BBS, TUGT and MBI scores. Conclusions: These findings provide evidence supporting the effectiveness of balance training programs in reducing fall risk and promoting health and wellbeing among community-dwelling elders. Future research should aim to refine the design of these programs and assess the sustainability of the observed improvements.
