The number of buildings certified by GBCS(Green Building Certification System) has increased, especially in school facilities recently. It seems to be resulted from growing interest in 'Low Carbon and Green Growth'. But new version of the GBCS is urgently needed because the initial GBCS has been used too long time without any fundamental update. The purpose of this study is to contribute to the improved GBCC(Green Building Certification Criteria). For this, the enforcement background and developing process of GBCS were reviewed and a spot survey was conducted to find out the poor maintenance of adopted technologies and the problems in applying the GBCC for the certified school facilities operated for longer than 1 year. The new version of GBCS including GBCC based on the result of this study is hopefully turned up to be enforced soon, resulting in marking conspicuous distinctions between certified school and ordinary school.

본 연구는 중국 혹은 중국인 대상 제주의 우호적 이미지 확립을 위해 한반도 사드(THAAD)배치 전후, 중국 주요 언론매체와 인터넷 게시판에 대한 제주 이미지 분석을 실시하였으며, 온라인 공간에 게시된 텍스트를 대상으로 사회관계망분석(Social Network Analysis)을 통해 이를 구체화하였다. 결과적으로 본 연구의 주요목적은 객관적 수치에 근거한 연구방법을 활 용하여 중국 내 제주지역 인지도 제고 방안을 모색하고, 제주의 지역경제를 활성화하는데 도움이 되고자 함에 있다. This study is designed to identify the image frame of Jeju developed by China, and based on this, to establish friendly image on Jeju for China or Chinese people. To confirm this, the study analyzed the image of Jeju in major Chinese media and internet message boards before and after the THAAD deployment. In addition, the texts posted on the relevant online space were specified through Social Network Analysis. As a result, the main purpose of this study is to seek improvement plan for Jeju s awareness in China by using research methods based on objective figures and to activate local economy of Jeju. The results of the study are as follows. First, the image of Jeju appearing online of China is different in macroscopic unit of China and microscopic unit of Chinese people. While Chinese government views Jeju from the perspective of China s government policy, Chinese people tend to view Jeju as the object of tour/travel. Second, the THAAD deployment has a great effect on the mutual relationship between Jeju and China not to mention the relationship between Korea and China. The THAAD deployment has a considerably negative effect on the image of local unit beyond the relation between Korea and China. Third, it was confirmed that developing new image of Jeju and focusing on the new image are necessary. Chinese people show attention on individual travel/tour, which didn t exist before. There is growing interest in individual travel programs such as exploring Jeju s traditional culture and restaurants and shooting honeymoon photos.

Korea and Japan is called a relationship of `close but distant.` The reason relies on experiencing together many interwined conflicts or cooperation. Thus this study`s objectives include investigating Korea-Japan collaboration history, assessing inhibiting factors in the tourism cooperation, and suggesting several suggestions. As current issues emerging between two nations, diplomatic conflicts, lack of tourism infrastructure in Korea, tourism image of the two countries, some problems in cultural exchange are described. Suggested solutions include cutting down on emotional measures on diplomatic issues; cooperation between civilians, municipalities, and central governments; strengthening competitiveness of Korean cultural tourism; and enhancement of tourism image. This study explored historical exchange, inhibitors and solutions emerging in the middle of tourism cooperation. Without deliberating the kaleidoscope of worldwide situations intermingled among countries this is likely to be a delusive and erroneous approach to estimate mutual tourism flow. Thus in a situation of development of numerous economic model techniques, future study is needed to identify influential external factors over history to predict future tourism demand, not depending only on past tourism-related numbers. This will more precisely estimate tourist flow and reasons for increasing or decreasing tourist demand between the two countries which share a favorable and unfavorable history because of territorial issues or different religions or ideologies.

Among the augmented reality services, the most frequently used services are marker based augmented reality services. However, there is a problem that the augmented reality service can not be provided in an environment in which the marker image can not be recognized. In this paper, we propose a method to provide more stable service by estimating the user’s posture even if the marker image can not be correctly recognized due to occlusion, obstacle or marker damage in the marker based augmented reality. In the proposed method, when a failure occurs in the provision of a marker based augmented reality, the attitude of the user is estimated using the 3-dimensional coordinates measured through communication between the three beacons and the user, and it allows the user to receive the augmented reality service continuously. We describe the scenario of augmented reality technique using proposed marker recognition and beacon communication, and present the results of experiments based on the degree of occlusion and damage. 증강현실 서비스 중 가장 많이 사용 되는 서비스는 마커기반 증강현실 서비스이다. 그러나 마커 이미지가 가림 또는 훼손 때문에 마커 이미지를 인식될 수 없는 환경에서는 증강현실 서비스를 제공해줄 수 없다는 문제점이 있다. 본 논문에서는 마커기반 증강현실에서 마커 이미지를 인식할 수 없는 상황에서도 사용자의 자세를 추정함으로써 보다 안정적으로 서비스를 제공하는 방법을 제안한다. 제안하는 방법은 마커기반 증강현실 제공시 장애가 발생할 경우, 3개의 비콘과 사용자간의 통신을 통해 측정된 3차원 좌표 값을 이용하여 사용자의 자세를 추정하고 증강현실 서비스를 제공함으로써 사용자가 지속적으로 증강현실 서비스를 제공 받을 수 있도록 한다. 제안된 마커 인식과 비콘 통신을 활용한 마커기반 증강현실 기법의 시나리오에 대해 설명하고 제안된 방법을 가림 및 훼손 정도에 따라 실험한 결과를 제시한다.

본 논문에서는 고정익항공기와 회전익 항공기의 장점을 결합시킨 신개념 복합형 무인항공기인 QTW(Quad Tilt Wing)의 종축 동특성을 연구한 결과를 기술하였다. 설계된 QTW 무인항공기는 Tandem Wing 형상을 가지며 각 주익의 끝단에는 프로펠러를 구동하는 모터를 장착하였다. 비행역학적 분석을 위해 모멘텀 이론을 이용해 추력을 계산하였으며, 틸트 각도에 따른 프로펠러의 Slip stream에 의한 양력과 항력을 고려한 비선형 모델링을 구축하였다. 또한 트림분석을 통해 설계된 비행체가 적절한 비행속도 대비 틸팅각을 가짐을 보여주었으며, 각 트림 점에서의 성분별 힘을 분석하였다. 각 비행 모드의 선형모델 고유치 분석하여 동적 특성을 분석하였으며 고정익모드로 전환됨에 따라 안정한 부분으로 극점이 이동함을 확인하였다. A Quad Tilt Wing UAV is a new concept hybrid UAV having the advantages of both fixed-wing and rotary-wing aircraft. This paper presents longitudinal flight dynamic characteristics of a Quad Tilt Wing UAV. The designed Quad Tilt Wing UAV is a configuration of a tandem wing type aircraft with an actuating motor and propeller mounted at each wing. Momentum theory is used to calculate the thrust, and nonlinear modeling is performed considering lift and drag generated by slip stream effect of propellers. Also, Force and moment variation at each tilting angle is considered. Static trim on longitudinal axis is analyzed via numerical simulation. Componentwise force contribution was analyzed at each trim mode. Dynamic characteristics were evaluated through eigenvalue analysis for a linear model at each flight mode. It is verified that longitudinal dynamic characteristics are changing from unstable to stable state by continuous transition of dominant poles.

Background: The Quality of Life Questionnaire for Adult Korean Asthmatics (QLQAKA) is a valid and reproducible tool for evaluating and monitoring Korean adult asthmatics. However, the questionnaire is still burden to some patients, so we developed a simplified global self-assessment scoring. Objective: The goal of this study is to compare the patient``s global self-assessment scoring method with the QLQAKA and evaluate how it reflects quality of life (QOL) of asthmatics. Method: One hundred ninety-nine adult asthmatics were enrolled and asked to answer the QLQAKA composed of 17 items in 4 domains (activity, symptom, emotion and exposure to environmental stimuli) and one more global self-assessment question with a 5-point scale was added. According to the Global Initiative for Asthma (GINA) 2006 guidelines, patients were divided into 3 groups: controlled, partly controlled and uncontrolled groups. Then, we analyzed the relationships between the QLQAKA scores, global self-assessment scores and various clinical parameters. Result: The mean QLQAKA score and global self-assessment score were statistically significantly different between the 3 groups. Pulmonary function tests were also statistically significantly different between the 5 QLQAKA score subgroups as well as 5 self-assessment score subgroups. Moreover, global self-assessment scores were well correlated with QLQAKA scores. Conclusion: In a busy outpatient clinic, we may estimate the QOL of asthma patients using a simplified patient``s global self-assessment scoring method.
