The green roof industry have been developed with Europe, North America, Japan. At the same time, being recognized the important of green roofs in domestic industry and we just start to develop the relative technology as analyzing the future direction of advanced technology. Recently, local self-government including Seoul support the system for green roof which provide 50% of working expenses form of Matching Fund by Seed Money. As years go by, the number of build up the green roof has gradually increased to be proved. At this result caused by management of system in government, unstructured construction system, low development of support technology. In this study as analyzing the present of technical development, supporting by law and system for the advanced waterproofing and root penetration resistance technology, we suggest the development direction of it to be compared with application advanced technology and we could strengthen the international competitiveness to be industrialized the green roof considering system, technology, human infrastructure.

Purpose: The purpose of this study is a finite element analysis of supporting bone according to custom abutment angle. Methods: Implant fixture was selected with a diameter of 4 mm and the length of 13 mm. The fixture and abutment was designed by a combination of the abutment screw clamping force to produce a custom abutment model of $0^{\circ}$, $15^{\circ}$, $25^{\circ}$ and $35^{\circ}$. The loading condition of 176 N was applied to the lingual surface of the crown, near to the incisor edge, and horizontal load. An oblique load of $90^{\circ}$ was applied long axis of the implant fixture analyze the stress of supporting bone. Results: The result of mechanical analysis was observed that the supporting bone stress analysis of the horizontal load, the von Mises stress values (MPa) are given in the order of TH00 (432.6) > TH25 (418.0) > TH15 (417.4) > TH35 (415.8), the oblique load, the von Mises stress values are given in the order of TO00 (459.3) > TO15 (399.6) > TO25 (374.8) > TO35 (343.4) Conclusion: The $35^{\circ}$ abutment over the current clinical tolerance limits will be available for clinical application.

지지구조물 위의 부시스템으로 이루어진 계의 고유 진동수와 모드형을 근사적으로 구하는 식을 유도하였다. 이 계는 이산계로 모형화되었고, 부시스템의 질량은 지지구조물의 질량에 비하여 매우 작다고 가정하였다. 기본진동수는 지지구조물에 대응하고, 고차 진동수는 각각의 부시스템에 대응한다는 것이 밝혀졌다. 또한 지지구조물이 조화력에 의해 가진될 때 지지구조물과 부시스템의 진동 진폭 사이의 관계를 유도하였다.

In recent years, the solar cell market has steadily grown with the demand for new energies. And wire sawing is one of the most critical processes in manufacturing solar cell wafer which is supposed to affect the breakage of wafers most during the process and afterwards. Generally, the defects of the wafers are generated from the structural vibrations of the machine. In the sawing process, the vibrations cause unnecessary normal stress on the cut surface of wafers, and eventually create the surface damage or leave the residual stress. In this study, the dynamic properties of a wire saw have been analyzed through the frequency response test and the computer simulation. And the effects of the design alterations have been investigated to stabilize the machine structure and further to reduce the vibrations. The result shows that relatively simple design alterations of supporting structure without any change of major parts of the machine can suppress the vibrations of the machine effectively.

Objectives This paper is focused on the development of supporting device for the direct moxibustion. This device makes one help to do moxibustion on one's head and back for oneself. Without this device, one can't avoid the other's help to do moxibustion on one's head and back. Methods The design protocols of the supporting device for the direct moxibustion are determined. And 3 dimensional simulation using Ultimaker's 3D printer was carried out. The parts of the supporting device for direct moxibustion are followings: 1. preparing of the main parts which are divided into an acupuncture touching sting and moxa holder. 2. preparing a grip part. Results 3 different lengths of the acupuncture touching sting such as 3mm, 4mm, and 5mm were experimented for the perfect burning of moxa. Among them, the acupuncture touching sting with 4mm length was best for the perfect burning and for the organic functional tests. Conclusion The supporting device for direct moxibustion will be helpful to minimize of the burning of skin, the pain, and the smoke.

Purpose : The purpose of this study is balanced exercise program according to the supporting surface any affect women's ability to balance high heels. Methods : This study subjects were normal 20 females in their twenties. They were divided into stable supporting surface(n=10), unstable supporting surface(n=10), and they exercised three times a week for 5 weeks. In order to compare the difference of balance, the subjects were measured before and after training. Balance was examined using the balance master 7.0 version systems. Results : 1. There was significant difference values between pre-exercise and post-exercise of unstable surface group on the FORM-EO and FORM EC of MCTSIB and all of Unilateral Stance variables. 2. There was significant difference values between pre-exercise and post-exercise of stable surface group on the mean EPE, mean MXE, and mean DCL of LOS. 3. There was significant difference values between pre-exercise and post-exercise of unstable surface group of the rhythmic weight shift. 4. There was significant difference value in the slow directional control of rhythmic weight shift between groups after exercise. Conclusion : Training on stable supporting surface group and unstable supporting surface group improve balance.

Purpose: The dental implant should be enough to endure chewing load and it's required to have efficient design and use of implant to disperse the stress into bones properly. This study was to evaluate the stress distribution on a supporting bone by lengths and diameters of the implant fixture. Methods: The modeling and analysis of stress distribution was used for the simple molar porcelain crown model by Solidworks as FEM program. It was designed on applying with tightening torque of 20 Ncm of a abutment screw between a cement retained crown abutment and a fixture. The fixtures of experimental model used 10, 13mm by length and 4, 5mm by diameter. A external vertical loading on the two buccal cusps of crown and performed finite element analysis by 100 N. Results: The maximum von Mises stress(VMS) of all supporting bone models by fixture length and diameter were concentrated on the upper side of supporting compact bone. The maximum stress of each model under vertical load were 164.9 MPa of M410 model, and 141.2 MPa of M413 model, 54.3 MPa of M510 model, 53.6 MPa of M513 model. Conclusion: The stress reduction was increase of fixture's diameter than it's length. So it's effective to use the wider fixture as possible to the conditions of supporting bone.

본 논문의 목적은 정부에서 지원하는 자동화, 스마트 공장 구축 지원사업이 기업의 경영성과에 미치는 효과를 분석하는 것이다. 이를 위해서 t-test 및 ANOVA 등의 방법을 이용하였다 지원기업과 비지원 기업간 비교시 발생하는 실험집단과 통제집단간의 선택편의 문제를 해결하기 위해 PSM 방법을 활용하였다. 분석결과, 자동화 지원사업의 효과는 미미한 것으로 나타났으나 스마트 지원사업의 경우 일정 시차가 지난 후 매출액과 연구개발비가 증가하는 것을 확인할 수 있었다. 정부지원 효과가 나타나는데 어느 정도 시차가 발생하는 것으로 확인되었고 자동화 지원사업의 경우는 직접적인 영향을 주기 보다는 연구개발 비율 등과 같은 매개변수의 증대를 통해 장기적 매출 증대로 이어지는 것을 확인할 수 있었다. 본 연구는 정부 지원사업의 신규예산 확보와 개선방안을 모색하는데 유용한 기초자료로 활용될 것이다.
