Frank Lloyd Wright(1867-1959) was regarded as the pioneer of the modern architecture in the beginning and transition period of 20th century. His works have the pure shape form which have the deep relationship with the organic architecture. Wright told himself that the Froebel System had an influence on his works a lot. This study have researched about the three dimensional application of the Froebel System in his works with assembling and disassembling. Also the two dimensional application in the diagonal and circular plans are the one of the subjects here. The following conclusions are reached. First, The similar of the Wright's works and the Froebel System was the application of the similar principles rather than the copy of the method, which are the accent of the center, the composition of the part and whole, the understanding of the composition principle through the unit system and the unfolding of the crystal by rotation. Even thought the Wright's works have the triangle, square, hexagonal shape, the way of the expansion from the centered space was same. Also the space formed by the division of the center space, unfolds making the part and whole by overlap and continuation. The 2nd Froebel make space decided by the Net and Crystal Lattices which have the crystal characteristics by the rotation. The new geometric architecture, pinwheel, was created by this method. The application of the Froebel in the Wright's works have the several sets which are the 3th, 4th, 5th, 6th Froebels, 2nd, 7th Froebels and the 3th, 5th, 9th Froebels. The geometrical analysis of the square shape and the diagonal shape of the Wright's works was possible. The unfolding of the centered space can be found in the Guggenheim Museum using the analysis of the circular geometric of the 9th Froebel. The above study proves that the Froebel was not a mere tool for the basic shape training but also the main body of Wright's works which consists of the organic idea and philosophy of the space.

Ballast water filled into and discharged from the ballast tank of a ship has a negative impact on local marine environment due to various aquatic organisms contained therein. The IMO developed and adopted "The International Convention for the Control and Management of Ships Ballast Water and Sediments, 2004" with the purpose of protecting the marine environment from transfer of harmful aquatic organisms in ballast water carried by ships. The IMO BWM Convention was approved in September 2016 and ships must be equipped with ballast water management system after September 2017. Ships' ballast water treatment methods are divided into using active substances as electrolytic type, ozone type, chemical dosing type and using physical treatment type as filter type, ultraviolet type. It is also used with a combination of two methods. Electrolysis is superior in terms of cost and efficiency. In this study, basic principles, components, and land base test contents of electrolysis ballast water treatment system, a direct electrolyzed ballast water treatment system, were examined. Land base test was conducted with 300m3/h capacity device at the KIOST Geoje plant where the government test facility was installed. This test validated that the system meets IMO standards.

Currently, black-box-based machine learning algorithms are used to analyze big data in manufacturing. This algorithm has the advantage of having high analytical consistency, but has the disadvantage that it is difficult to interpret the analysis results. However, in the manufacturing industry, it is important to verify the basis of the results and the validity of deriving the analysis algorithms through analysis based on the manufacturing process principle. To overcome the limitation of explanatory power as a result of this machine learning algorithm, we propose a manufacturing big data analysis method using genetic programming. This algorithm is one of well-known evolutionary algorithms, which repeats evolutionary operators such as selection, crossover, mutation that mimic biological evolution to find the optimal solution. Then, the solution is expressed as a relationship between variables using mathematical symbols, and the solution with the highest explanatory power is finally selected. Through this, input and output variable relations are derived to formulate the results, so it is possible to interpret the intuitive manufacturing mechanism, and it is also possible to derive manufacturing principles that cannot be interpreted based on the relationship between variables represented by formulas. The proposed technique showed equal or superior performance as a result of comparing and analyzing performance with a typical machine learning algorithm. In the future, the possibility of using various manufacturing fields was verified through the technique.

This study analyzed the service philosophy of Eastern mainstream thought in order to establish a service philosophy. Following a prior study the "study of the service philosophy of major korean ideology", we explored the service philosophy of the Eastern mainstream ideology of China and India and it's coherence. The existing basic structure and operational model of service philosophy were presented in depth and the service philosophy of Oriental mainstream thought was derived. The philosophy of service can be presented as an idea of the structure of the service and as an idea of the operation of the service. It suggested compatibility of the service philosophy of Asian mainstream ideas, and analyzed them mainly in China and India. Indian ideas revolved around the ancient philosophy of Veda, Upanishads philosophy, and representative Buddhist philosophy. It also showed that a major trend of mainstream ideas in China and India was found to be compatible with the service philosophy. Follow-up studies are needed to further refine the structure of service philosophy and develop the principles of operation into larger ideas in the future, and a study of conformity of service philosophy in representative Western ideas, focusing on Greek, Roman, and German philosophy, is also required. Ultimately, it is necessary to establish a service philosophy as an ideological base that drives future economic and social development.

This study analyzed Korean representative ideology to establish a service philosophy. As a follow - up study of the service philosophy consistency study of the Korean original idea, we searched for the coherence as the philosophy of the service age in the Korean representative ideology. The basic structure and operation model of service philosophy are presented, and the service philosophy of major korean ideology is derived. The philosophy of service can be presented by the structure of service and the operation of service. The essential characteristics of the service are relationship, interactivity, horizontality, and harmony, and the service structure that reflects this is the coexistence of products and services. Based on the discussion on the structure and operation of the service philosophy, the service philosophy synthesis of Korean representative ideology is presented. From the Silla era to the Koryo dynasty, the essence of Korean Buddhism thought is in line with the service philosophy, and it was found that Toegye and Yulgok to Dasan's thoughts are also consistent with service philosophy. In the future, we need further studies to refine the structure and operational principles of the service philosophy and to develop it into a big idea. In addition, it is necessary to follow up the service philosophy of Oriental representative ideology centering on Chinese and Indian philosophy. Ultimately, it is necessary to establish a service philosophy as the main philosophical thought and to establish a service philosophy as a desirable future economic and social philosophy.

The world has been rapidly restructured in an agenda of national security from center of military strength to that of economic strength since the post cold-war era China military leadership-division carried out RMA through learning of a lesson from Gulf war in 1990 -1991 and Iraq war in 2003, thus the leadership-division made an attempt to convert the military system to a technical intensive system. The principle based on RMA of China military is (National defense strategy) drafted by the central military committee 1985 and (Four modernization general principles) 1978. China has introduced Russian high-technological arms and equipment in order to build up the military arms greatly thanks to an economical development, and they take pragmatism line as chinese socialism with their strategy to make secure a position as military powers such as they successfully launched a manned spacecraft and are building an air-craft carrie and soon. USA has a theory of dichotomy whether a country is a cooperator for USA, or not. and also enemy or friend since 9.11terror, thus USA is different from their direction of police. This is because USA stands a position as the superpower of the supremacy hegemony of the world. We must be carefully aware that USA considers as important area for Middle east, West south Asia, Central Asia and Northwest Asia to meet the demands of 2lcentury. Accordingly, the focus of USA's military strategy will be probably concentrated at the above mentioned four areas. On the other hand, USA enjoys such a superpower position due to collapse of USSR which was the past main enemy since the post cold war era. We could give an conclusive example as fact that USA has recurred to unilateralism But USA carry on the military operations to the terror groups at global around by converting thje military strike strategy to pre-emptive strike strategy since9.11 terror, 2001. USA seeks for transformation to the mobile military forces with light-quantity oriented in order to carry on such the military operations and makes progress GPR, And the USA forces in Korea makes progress a military renovation as part of such a military strategy. On the other hand, USA promotes the measures of choose for the countries standing at the crossroads of strategy and carries forward a main scheme of provision for four priority aims that the leaders of a hostile country and mis-country shall be prohibited from use and obtainment of weapons of mass destruction. Accordingly, this treatise found out a significant meaning to have an effect on the national security in the korean peninsula.

The purpose of this study was to establish and apply 'term learning strategy' for learners whose basic skill, interest, and motivation for learning is lower, and to increase the learned capabilities of subjects' 'industry introduction', required for industrial technical high school students. Another purpose was to identify when the learning strategy established was applied, its affect on how well learners understood terms in a particular unit of material, and, after instruction presented in accordance with 'term learning strategy,' evaluate the ease with which subjects understood the teacher's explanation of the unit of subject, how well they understand the main concepts of the unit of subject, and to what extent the presentation interested and motivated the subjects. The researcher established 'term learning strategy' based on the principles of Garg's "Nine Steps for Events of Instruction." The study included 35 first grade participants purposely selected from 33 classes at 1155 students in K industrial technical highschool. Data was collected via tests and surveys. Results indicated that 'term learning strategy' facilitated thorough understanding of terms and concepts related to the unit of subject, as well as a better understanding of the teacher's explanation and increased interest and motivation in learning. In addition, the "term learning strategy" increased interaction among learners in the instruction setting. Finally, implications of this study and implementation recommendations for this instructional strategy were presented.

Presence of microplastics in soil and groundwater has recently been reported and environmental concerns are raised as to the plastic pollution. In the subsurface environment, clay minerals and metal oxide minerals are commonly found as finely dispersed states. Because the minerals have high sorption capacities for diverse pollutants, interactions with mineral surface play an important role in the transport of microplastics in groundwater. Accordingly, environmental mineralogy investigating the interactions between microplastics and mineral surfaces is the essential research area to understand the fate and transport of microplastics in the subsurface environment. The microplastic-mineral surface research requires molecular- to nano-scale analyses to be able to probe the relatively weak interactions between them. The current report introduces a nano-scale analysis tool called quartz crystal microbalance (QCM) that can measure the sorbed/desorbed mass of nanoplastics on mineral surfaces at the level of a few nanograms (~10-9 g). This report briefly reviews the main principles in the QCM measurement and discusses applications of QCM to the environmental mineralogy research.
