In this paper, current industrial trend of simulator development which is widely spreaded and performed in globally is introduced. Usage of satellite simulator is becoming an essential choice since the complexity of satellite and mission is being continuously increased. Satellite simulation brings reduction of satellite development cost and of period which is consumed by test on satellite development for various phases. Further more, it can be used to reduce the development period of satellite since developed resource and knowledge is possible to be delivered to next program effectively.

The presence of the Fourth Industrial Revolution is omniscient, led by full force emergence of technologies that make biological, physical, and digital worlds borderless. All industries which jump on the bandwagon, can observe convergence and merging of bushiness happening within, between and across industries. As the shipping and port logistics industry is said to be in eye of this storm, the purpose of this study is to investigate the shipping and port logistics industry's awareness regarding 4th IR, as well to identify necessary countermeasures in responding to progression of this trend. Analytic Hierarchy Process (AHP) methodology was then used to compare the importance of four phases of countermeasures, reviewed by experts in the field. Results showed that countermeasures should be first orchestrated to the 'Merging and Integration of Inter-industry', then followed by 'P reemptive Introduction of Advanced Technology', 'Expansion of Intra-industry Businesses', and eventually 'Automation, Unmanned Technology'. Last but not least, four phases of countermeasures which should be introduced and executed one phase after another, are outlined for the shipping and port logistics industry to boost its competitiveness in addressing this progressive trend.

Purpose: The purpose of this study is to analyze the trend of quality research by analyzing the entire JKSQM(Journal of the Korean Society for Quality Management). Methods: This study is to analyze the frequency of words used in the abstract of the all JKSQM by applying the text mining processing. We use wordcrowd among text mining techniques. Results: 22 words of high frequency were presented in the abstract of the paper published in the JKSQM for 42 years. The frequency of words was shown on a 10 year basis, and the four important words were plotted on a change graph for each Vol. Frequent words of each Vol. are added in the appendix. Conclusion: The main research results are as follows. First, there has been no significant change in research trends over the last 40 years. Second, the early SQC words have been widely used, and since 1990, many words such as service-oriented words have been used, indicating a change in the times. Third, the use of the words of the 4th industrial revolution since 2010 is weak. In the above analysis, the trend of quality research in Korea is within the quality category and can be considered conservative. Now, it is expected that everything will be changed in the period of the 4th Industrial Revolution, and it is time to study the direction of quality in Korea.

The problems with unsorted municipal waste are always associated with disposal issues as it requires a large area for landfilling or high energy used for incineration. In recent years, an autoclaving technique has been considered a promising approach which could minimize the volume of organic waste from being directly disposed or incinerated. In this work, an attempt was done to study the saccharification potential of organic residues under elevated temperature Thermal treatment involving hot water bath was applied to treat the organic residue ranging from 60℃ to 100℃ for 30 and 60 minutes. The result obtained showed an increasing trend for the concentration of glucose and carbohydrate. However, the result for lignocellulose content which contains various component includes extractive, holocellulose, hemicellulose, cellulose and lignin show variation. Based on the thermal treatment carried out, the result indicated that the trend of glucose and carbohydrate content. The highest percentage of glucose that can be obtained 978.602 ㎍/ml which could be obtained at 90℃ at 60 minutes. The carbohydrate also shows an increasing trend with 0.234 mg/ml as the highest peak achieved at 80℃ for 30 minutes treatment. However, it was found that the lignocellulose content varies with temperature and time. The statistical analysis was carried out using two-ways ANOVA shows an interaction effect between the independent variables (temperature and contact time) and the saccharification effects on the food wastes. The result shows a variation in the significant effect of independent variables on the changes in the composition of food waste.

Modern Society is tuning to the wide organized social structure with highly varieties. To the cultural aspects in these days of the late-indusoial society, due to the post-modernism. This kind of trend was found in overall fields of studies. Therefore, the post-modernism is to be a kind of a modern spirit ruling over the late 20th century. Post-modernism is a vague expression, that was begun to appear in various artistic intellectual, ideologic trends with a repulsion of modern design after the World War II. The present age as a modern society slews a distinguished mark of undifferentiation disorganization and relaxation, disassembling of social structure. With the study on the background of occurrence, character and philosophy for the post-modernism, the theoretical background of post-modernism could be seen. According to the influence of post-modernism, the minimalism, retro-design, kitsch-design, deconstructionism-design deconstructionism-design, new materia1-design and cyber-design shown on each trend of modern industrial design were studied.

The purpose of this study is to develop a series of trend analysis models for industrial water consumption and to propose a blueprint for the integration of the developed models with GIS. For the consumption data acquisition, a real-time sensing technique was adopted. Data were transformed from the field equipments to the management server in every 5 minutes. The data acquired were substituted to a polynomial formula selected. As a result, a series of models were developed for the consumption of each day. A series of validation processes were applied to the developed models and the models were finalized. Then the finalized models were transformed to the average models representing a day's average consumption or an average daily consumption of each month. Demand pattern analyses were fulfilled through the visualization of the finally derived models. It has founded out that the demand patterns show great consistency and, therefore, it is concluded that high probability of demand forecasting for a day or for a season is available. Also proposed is the integration with GIS as an IT tool by which the developed forecasting models are utilized.

Since the human act to pursue beauty is the most natural desire and instinct, the demand for a new beauty trend in line with the 4th industrial revolution era, in which aesthetic interest in human appearance management along with the importance of appearance is increasing day by day is very necessary at this time. In order to derive the source from art, which is closely related to beauty studies, the shape and texture of women's hair design appearing in 'Chinoiserie' style Western paintings that were popular in Europe and France in the 18th century. As a result of the study, the hair design of women appearing in four Western paintings showed characteristics of each individual shape, texture, and color. Through this study, the foundation stone for the development of a new mode hairstyle for modern people living in a rapidly changing era while quarreling with the village, and the foundation stone for the development of various beauty contents.
