Many countries are trying to reduce a greenhouse gas to step up their fight against climate change. There are many studies related to building only for reducing a greenhouse gas in construction area but studies related to reducing a comprehensive environmental load including various pollutants that affects the global environment are lacking. This study aims to analyse the characteristics of environmental load by work type for tunnel projects. Analysis showed that seven work types, including lining concrete, shotcrete, tunnel portal and open-cut tunnel work, etc., are representative works generated environmental load. These seven works represent 89.22 percent of total environmental load. In addition, comparison results of environmental load per tunnel's length by work type showed that a major factor of environmental load is caused by a tunnel portal and open-cut tunnel work with relatively short length (excavation length). And lining concrete and shotcrete work are larger than any other environmental load with tunnel's total length. It is expected that the result of this study will be used to make a estimation model for environmental load using approximate quantity survey of representative work types in the early stage of tunnel design. And it will be play a considerable role in establishing of environment management plan for sustainable infrastructure construction.

This study aimed to examine the effect of microcurrent stimulation on expression of Bone Morphogenetic Protein(BMP) 4 after tibia fracture in rabbits. The twenty four adult 6 month old New Zealand white rabbits weighting 2.5~3.5 ㎏ were used. Twenty four rabbits with tibia fracture were randomly divided into control and experimental groups. Each group was divided into four subgroups, based on the duration of the experiment (3, 7, 14, 28 days). The experimental groups received microcurrent stimulation of 20~25 ${\mu}A$ intensity with surface Ag-AgCl electrode (diameter 1cm, Biopac, U.S.A.) for 24 hours a day. Cathode of the microcurrent stimulator located on the tibia directly, anode of it did on the gastrocnemius muscle. After evaluation, the test results are as follows: Comparisons of immunohistochemical observation of BMP-4 in 7 days after tibial fracture show that there was shown to be a moderate positive reaction (++) on concentric circles of Harversian system and the interstitial lamella in the control group, while there was a very strong positive reaction () on concentric circles of Harversian system and interstitial lamellain the experimental group. These results suggest that applying non-invasive constant microcurrent stimulation on fractured bone is helpful to bone healing.

용언은 그 어간이 여러 문법소와 결합하면서 자동적 음운 변동을 제외한 형태 변동이 있는가, 없는가에 의해 규칙 용언/불규칙 용언으로 구분할 수 있다. 이러한 불규칙 용언은 심성 어휘집에 어떤 형태로 저장되어 있으며, 규칙 용언과는 어떠한 관계가 있는지, 나아가 실어증 환자의 경우에는 정상인에 비해 어떤 행동장애를 보이며, 장애가 있다면 어느 경로의 손상으로 인한 장애인지를 알아보는 것이 본 연구의 목적이다. 이를 위해 이해성 실어증 환자 한 명과 음어적 실행증 현상을 동반한 경미한 정도의 실어증 환자를 피험자로 하였다. 실험 과제는 단어 채워 넣기 과제(word completion task)를 사용하였다. 즉 주어진 기본형 용언을 검사 문장의 문맥에 맞게 활용하여 채워 넣는 것이다. 실험 결과에 의하면 환자들은 규칙용언의 활용(예. 먹다/먹는)과 불규칙 용언 중 형태를 유지한 채로 활용하는 경우(예. 줍다/줍고)에는 거의 오류가 없었으나, 불규칙 용언이 형태 변화를 겪어야 할 경우(예. 줍다/주워)에는 대부분 오류를 보였다. 또 이때는 기본형(basic form)을 그대로 유지하는 오류 방향성을 관찰할 수 있었다. 이는 그간 문법으로 구분되어 오던 규칙 용언/불규칙 용언의 정보 처리보다는 형태 유지/형태 변화 정보 처리의 영향이 크다는 것을 알 수 있다. 특히 이해성 실어증 환자는 전체적인 오류율이 매우 높았는데, 규칙 용언의 경우에도 오류를 보였다. 이때, 용언의 어간에 해당하는 부분에는 오류가 없고, 뒤에 따르는 내용과의 관계를 파악해야 하는 문법 기능소, 즉 연결 어미에서 오류를 보여 정보의 유지, 통합에 문제가 있다는 기존의 연구와도 일치하는 결과를 나타냈다.환자는 시제 선어말 어미를 선택하는데도 어려움을 보임이 확인되었다. 실험 3 역시 실험 1과 실험2에서와 동일하게 처리의 어려움을 보였다. 이러한 실험 결과들은 국어의 존칭과 시제 선어말 어미가 통사부에서 구(XP)와 결합하여 새로운 구를 형성하는 통사적 접사로 해석할 수 있으며 Grodzinsky의 가설을 지지하는 결과를 보여 줌으로서 국어에서도 AgrP, TP, CP 사이의 통사적 위계가 있음을 뒷받침하는 증거가 된다.전처리한 Group 3에서는 IL-2와 IL-4의 수준이 유의성있게 억제되어 발현되었다 (p < 0.05). 이러한 결과를 통하여 T. denticola에서 추출된 면역억제 단백질이 Th1과 Th2의 cytokine 분비 기능을 억제하는 것으로 확인 되었으며 이 기전이 감염 근관에서 발견되는 T. denticola의 치수 및 치근단 질환에 대한 병인기전과 관련이 있는 것으로 사료된다.을 보였다. 본 실험 결과, $Depulpin^{\circledR}은{\;}Tempcanal^{\circledR}와{\;}Vitapex^{\circledR}$에 비해 높은 세포 독성을 보여주공 있으나, 좀 더 많은 임상적 검증이 필요할 것으로 사료된다.중요한 역할을 하는 것으로 추론할 수 있다.근관벽을 처리하는 것이 필요하다고 사료된다.크기에 의존하며, 또한 이러한 영향은 $(Ti_{1-x}AI_{x})N$ 피막에 존재하는 AI의 함량이 높고, 초기에 증착된 막의 업자 크기가 작을 수록 클 것으로 여겨진다. 그리고 환경의 의미의 차이에 따라 경관의 미학적 평가가 달라진 것으로 나타났다.corner$적 의도에 의한 경관구성의 일면을 확인

웹이 등장하면서 지금까지 인터넷 상에서 텍스트와 이미지를 이용하여 정보를 표현하고 전달하는 방법이 가장 많이 사용되어왔다. 그러나 웹 관련 기술의 비약적인 발달과 네트워크 속도의 증가 및 인터넷의 급속한 보급으로 단순한 텍스트와 이미지 중심의 HTML 문서를 이용한 정보의 전달이 아닌 멀티미디어 데이터를 이용한 정보의 표현과 전달이 점차 증대되고 있다. 이에 따라 멀티미디어 데이터를 전송하기 위한 스트리밍 프로토콜도 등장하였다. 최근에는 컴퓨터의 성능 증가 및 네트워크 속도의 증가(초고속 통신 서비스의 보급)에 의해 멀티미디어 데이터의 전송이 가능하게 됨으로써 기존의 공중파나 CATV 방송국의 형태 지니고 인터넷 상에서 실시간 생방송 서비스와 VOD(Video On Demand) 서비스를 제공하는 인터넷 방송국이 급속하게 생겨나고 있다.

This paper has attempted to propose a more progressive direction for U-environmental sculptures in a ubiquitous urban space in terms of usability, service, function and formative characteristics that enhance user satisfaction with these sculptures. For this, Media Pole, a U-environmental sculpture on Gangnam U-Street, has been examined. The results of this study are as follows: First, a study of user satisfaction was planned after establishing levels of satisfaction in terms of service, function and formative characteristics. In terms of satisfaction by the section of Media Pole, the public transportation map was the most influential in service while street culture and beauty of shape were critical in function and formative characteristics, respectively. In the relationship between satisfaction by section and overall satisfaction, furthermore, functional satisfaction had the biggest influence. Therefore, the development of human-centered functional factors which have pleasant and touching stories to facilitate communication with citizens are important in order to develop various Media Pole contents to enhance user satisfaction with the U-environmental sculpture and allow it evolve into a Gangnam landmark Since we are in the initial stage of a U-city, there are many problems that need to be addressed such as a lack of natural beauty, poor material quality of environmental sculptures, absence of storytelling, poor technology, lack of content, poor profitability and lack of means of social communication. In the end, the development of a comfortable, people-friendly space and U-environmental sculptures are needed in consideration of economic, social and cultural aspects instead of focusing on advanced technology only.

The study shows solutions of long-term unexecuted urban park and activation plans to facilitate the business promotion of Private Park Developers. This study conducted a feasibility analysis to determine if the business of a special case is applicable. The result of this study is as follows about three long-term unexecuted urban parks in Gwangju Metropolitan City's City Park. First, the three long-term unexecuted urban parks in Gwangju Metropolitan City's City Park are the forest type Neighborhood Parks. Businesses of a special case's park developing cost(average 0.4%) have a relatively low percentage. It is most affected by Land Compensation(average 33.8%) and building construction expenses(average 59.1%). Second, long-term unexecuted urban parks' Land Compensation and building construction expenses seed capital are excessive. The Bongsan Park balance floor space index is 179 percent; a reasonable profit floor space index is 220 percent. The Mareuk Park balance floor space index is 351 percent; a reasonable profit floor space index is 420 percent. The Jungoe Park balance floor space index is 327 percent; a reasonable profit floor space index is 400 percent. Third, to facilitate the business of special cases in deliberating, Bongsan Park should change its second class general residential area. Jungoe Park must change the quasi-residential area and semi-residential area. Mareuk Park must change the general commercial area. In this way, the feasibility of promoting private park projects will be improved.

This study aims to assess the training effect of QFD(Quality Functional Deployment) program for 3 years over startups, adopted from the conventional QFD widely used in the large companies to break up to a sluggish sales and growth, for employees working in startup whether the participants in startup and venture company taking this lessons into their real tasks or not. In particular, the focus of this study falls on figuring out whether individual characteristics of the participants play a role in moderating effect over transfer intension factors and its link path structure. The research results drive out two significant findings. First, in terms of relationship between the influence of transfer intension by self-efficacy and the validity of training content with the learner's readiness, the moderating effect of demographic features of the participants is effective partially by the sex and fully by their working position, but not statistically significant by age, education, and the prior startup career. This research deliver the following significant implication that the active participation of CEO level, decision-maker guarantee the higher performance of the training program like QFD program, more stresses falling on practical implementation in real business rather than just ending up with career training. This study gives significant policy implication to quasi-government organization running all public startup training projects.

In this study, we examined the accuracy of the assessment items for selecting start-ups used in the project to support start-ups and verified their validity in determining whether they are appropriate assessment items based on selection criteria. The results of 973 start-ups that applied for the project fostering startup leading universities were collected and logistic regression was performed using SPSS 18.0. The study results are summarized as follows. First, the differences in characteristics of start-ups were identified in terms of selection. Second, the impact of selection by assessment items was gender in 2015, capability of the founder, business establishment in 2016, performance and potential in the global market, and business startup in 2017. Third, the overall selection accuracy analysis for the last three years confirmed that the accuracy of the selection is lower each year and that the accuracy of the selection is lower than the accuracy of the non-selection. This means that the current assessment items for selecting start-ups are inaccurate for selection, and that changes in the items due to changes in the start-up environment each year have led to lower accuracy of selection. It is meaningful that this study raised the importance of assessment items and the need for improvement of assessment items for the screening functions of good start-ups to enhance efficiency of the policies for startup support.

Issues of declining growth and vigor in forests are major concerns in many areas around the world, especially in response to predictions in the 1980s of widespread forest declines. This paper summarizes the current state of knowledge for forests in North America, Europe, and East Asia. Forest declines near point-sources of pollution(such as metal smelters) have been well recognized for a century, but evidence of widespread impacts away from point-sources remains relatively uncommon. In North America, significant forest decline has resulted from high concentrations of ozone near Los Angeles, California, and around Mexico City. Some high-elevation forests of red spruce in the eastern U.S. have declined in the past 20 years ; evidence indicates a role of low-pH fog in reducing they cold-tolerance of spruce. In Europe. most attention has focused on Norway spruce stands that developed yellow foliage, needle loss, and in some cases mortality. This syndrome appears to be related generally to an inadequate supply of magnesium, perhaps coupled with a very high supply of nitrogen. Despite localized areas that show declining trees, overall stand growth and standing biomass in Europe increased from. 1970 to 1990. Much less information is available for East Asia. Many industrialized regions in China have a pH of rain <4.5, and some connections between pollution and forest decline have been suggested. Pollution impacts on forests near cities in Korea include needle chlorosis, reduced needle retention, and declining species diversity. Overall, temperate forests show no widespread declines, and no evidence of substantial effects of pollutants on forest growth or vigor. Small areas showing declining forests may indeed demonstrate pollution impacts, and may provide cause for concerns about future impacts on larger areas.

The modern urban planning of Qingdao began in the early 20th century by the German colonization. At that time, the Germans adopted the modern urban planning philosophy and standards for building high-level cities in Qingdao's planning. Therefore, in the turmoil that followed the period of Japanese occupation and the Republic of China, although urban planners constantly changed, they always planned according to the initial plans of the city. Therefore, this paper conducted a time division on the urban planning of the Qingdao colonial period through an analysis of various literary materials by combining the historical backgrounds of different periods. This can be the basis for an analysis of current urban planning in Qingdao. This paper is divided into seven chapters. Chapter 1 is the introduction for description purposes and scope. In Chapter 2, the Urban Planning of Qingdao in the Chinese Colonial Period is confirmed and explained. Chapter 3 concludes the characteristics of the planning.
