Reverse osmosis(R/O), ultrafiltration(UF) and microfiltration (MF) processes are widely used for water treatment. In the seminar, characteristics of typical membrane modules including tubular, hollow fiber, plate and frame and spiral wound types will be discussed in detail. The design methods based on hydrodynamics for hollow fiber and spiral wound modules will be introduced analytically. Concentration polarization (CP) and membrane fouling mechnism as well as the techniques for CP reduction will be handled. The CP control techniques contain chemically modified membrane surface, pretreatment of feed water, operation of low trans-membrane pressure, chemical or physical cleaning methods and artificial production of various fluid turbulences near the membrane surface, etc. In especially, the recent commercial membrane modules for CP control including module rotation, vibration and Taylor or Dean vortex system will be introduced and discussed in detail.

Purpose : The purpose of this study was conducted to find treatment of forward head posture and shoulder instability with proprioceptive neuromuscular facilitation concept. Methods : This is literature study with books, seminar note and international course. Results : Forward head posture and shoulder instability has related each other. Forward head posture will make muscle instability, weakness and stiffness on neck and shoulder girdle. It will make pain also. Important muscle are suboccipital muscles, omohyoid muscle, sternoclaidomastoid muscle, scaleni, pectoralis minor, levator scapular and digastric. Conclusion : Treatment of the forward head posture and shoulder instability is provided. It is that treatment of stiff muscle with eccentric muscle work, muscle elongation, muscle strengthening at the structure level and at the functional level for daily activities.

This study employs a case study method to examine the current implementation of student teaching program in a particular teacher education institution and its affiliated school. The purpose of this study is to improve the quality of home economics student teaching program by promoting collaboration of teacher education institution and host schools. Following five research problems are addressed : (1)Examining the problems of student teaching from the literature review ; (2)Identifying the problems of student teaching recognized by home economics student teachers ; (3)Identifying the problems of student teaching and plans for improvements suggested in the seminar held for home economics teacher ; (4)Analyzing and comparing the differences of opinion between home economics student teaching program ; and (5)Suggesting alternative implementation plans for improving student teaching program by promoting collaboration of teacher education institution and host schools.

Objective : The purpose of this study was conducted to find treatment approach, functional test process with proprioceptive neuromuscular facilitation(PNF). Method : This is a literature study with books, seminar note and book for PNF international course. Result : Suggest of the functional test with functional level and structural level treatment approaching with hypotheses and problem list from the functional test and provide how, what, where for the treatment with the level. Conclusion : Treatment plan and approach has changed from disease to structure function, performance, participation the life, relationship with environment factors of human being. For the treatment approach need the functional test and functional goal.

At the University of Queensland (UQ), research into the performance of high-speed (in excess of 7000km/hr) air-breathing engines in the form of supersonic combustion ramjets (or scramjets) has been made for almost 20 years. This has been possible because the T3 and T4 shock tunnels, located at the ANU and UQ, respectively can simulate these conditions. However, like all facilities, there are differences between the flow generated in these facilities and that, which occurs in flight. The correlation between the two has not been determined for these facilities, or indeed for any shock tunnel performing supersonic combustion experiments. The aim of the HyShot flight program is to obtain this correlation by undertaking a sounding rocket program based at Woomera in South Australia. The seminar will discuss new approach taken by the UQ researches in developing this cost effective flight program, as well as the triumphs and disappointments which have been encountered so far in completing this somewhat ambitious program.

In the case of korea, it was enforced the performance based design in 2011 for fire safety to the construction that is hard to safety secure by code based design. However as a result of domestic performance design case analysis, as it conducts that the standard is insufficient, most of cases show that they use the method of adding facilities by strengthening legal standards. Therefore on this study, it conducts the analysis of Performance based design seminar data that it was done by SFPE and each countries Performance based design guidelines. Also based on this, it will use the basic data for developing the domestic performance based design guideline.

A study on techniques to evaluate auditorium assignment visible efficiency using three-dimensional simulation. The most important thing to be considered is to ensure the visibility to the podium upon assigning auditorium of venues, classrooms or seminar rooms. However, since there are so many variables to be considered such as the form of the stage, the area and height of the stage, size of screen, and the distance and angle of the auditorium from the podium, the methods to assign auditorium are staying at the level of basic for a long time. Thus, in this study, we proposed simulation methodology to quantitatively evaluate the three-dimensional visible efficiency based on Visual Graph Analysis (VGA) theory. After analytical methodology manufactures application, it sets examples of visibility depending on location of screen, visibility depending on degree of height difference and visibility about three-dimensional Mass Zoning like a stage and verifies the efficacy. In addition, based on results, visibility expectation curve is drawn and the method to calculate the stepped height depending on necessary visibility is proposed.

This surveillance research drafted a conservation plan of regional green spaces, on a metropolitan area level, geared toward the Minuma Tanbo area of 1260 ha, located in Saitama City, in the suburbs of Tokyo. It was an effective method, applied to an area where Japan's current issues on regional green space were epitomized, as it formed symposiums consisting of various personnel, and the opinions of the citizen had been reflected.

실험동물을 이용한 생식독성시험 결과를 기초로 하여 화학물질의 인체내 최기형성 발현 잠재력을 추정하는 질적인 독성평가는 비교적 용이하다. 그러나 인체에 실제로 적용할 수 있는 생식 독성 평가를 위해서는 양적인 독성평가가 요구되는데 여러가지 기본원칙의 불일치성과 검색기술등의 부조으로 아직 학문적인 평가가 어려운 실정이다. 따라서 본 seminar에서는 양적인 독성 평가의 어려운 문제점에 대한 세계적 연구추세를 소개하는 일례로서, 독일 베를린 자유대 독성학 연구소에서 다년간 수행된, 약제의 동물실험결과를 토대로 최기형 효과에 대한 평가시 고려해야 할 제반요소와 원칙에 대해 다음과 같이 소개하고자 한다.

The purpose of this study is to discuss the current status and limitations of convergence education in universities and to explore new possibilities of engineering convergence education by analyzing characteristics and cases of self - design semesters as convergence education. As a result of this study, it was found that the education for fostering convergence ability is insufficient for the viewpoint of education. The types of convergence education could be classified into three categories. However, the concept and paradigm of convergence education has not been established precisely because it is made in a 'top-down' manner by the government. In addition, there was a limit of the lack of a foundation to operate the convergence education. However, A university's self-design semester, it shows the possibility of cultivating the overall convergence ability by giving autonomy and subjectivity to learners and through the acquisition of contextual knowledge and the ability of collaboration.
