도로부문의 온실가스배출량 산정시 활용되는 tier3방법론은 주행거리데이터를 기반으로 한다. 하지만 기존 대부분의 자료들은 단독으로 지역단위의 주행거리를 대변할 수 없고 지역별, 차종별, 연료별, 도로유형별 특성을 반영한 통합활동자료(주행거리데이터)가 미흡하여 온실가스배출량 산정의 신뢰도가 부족하다. 따라서 본 연구는 첫째, 지자체단위(배출지점)의 정확한 온실가스배출량을 산정할 수 있는 주행거리기반의 활동자료(통합데이터베이스) 구축과 이를 활용한 온실가스배출량 산정방법론을 제시하는 것을 목적으로 한다. 이를 위해 교통안전공단의 주행거리자료, 국토해양부의 차량등록통계, 도로교통량, 한국교통연구원의 국가교통데이터베이스, 지방자치단체 평균속도 등을 활용하였으며, 이는 교통관련 데이터의 통행패턴(유 출입교통량, 내부교통량)을 반영하여 지자체단위(배출지점)의 산정방법을 제시하였다는 점에서 의의가 있다. 둘째, 본 연구에서 제시한 방법론 검증을 위해 적용대상지를 서울시로 하였으며, 본 연구에서 제시한 모형의 검증을 위하여 기존에 발표된 세 가지 온실가스배출량 산정결과와 비교하여 적정수준임을 제시하였다.

The Jinshanling section of the Great Wall of China is a series of fortifications in northern China that was constructed for strategic military defenses. This section was first built in the beginning of the Ming Dynasty in AD 1368 and then underwent major construction, reconstruction and renovation during the late Ming Dynasty, approximately in AD 1569. The Jinshanling section is 10.5 km long, a very short section compared with the entire 21,200 km wall. The wall section is located in Luanping County, Hebei province, China. This research paper focuses on the construction methods and materials of the wall and the towers in the area. The research methodology includes site visits, knowledge acquisition of experts and 3D graphic modeling. This study reveals that the materials selected for the structure include rubbles and rammed earth, bricks, stones, timber, and mortar. The erection sequence of the wall and the towers was a bottom-up fashion using various ancient construction techniques, such as the fire-setting rock blasting techniques and the surveying techniques from the Sea Island Mathematical Manual.

This article reviews the multiscale nature of stress corrosion cracking (SCC) observed by high-resolution characterizations in austenite stainless steels and Ni-base superalloys in light water reactors (including boiling water reactors, pressurized water reactors, and supercritical water reactors) with related opinions. A new statistical summary and comparison of observed degradation phenomena at different length scales is included. The intrinsic causes of this multiscale nature of SCC are discussed based on existing evidence and related opinions, ranging from materials theory to practical processing technologies. Questions of interest are then discussed to improve bottom-up understanding of the intrinsic causes. Last, a multiscale modeling and simulation methodology is proposed as a promising interdisciplinary solution to understand the intrinsic causes of the multiscale nature of SCC in light water reactors, based on a review of related supporting application evidence.

The purposes of this exploratory study were to interrelate the scholastic discipline of the ‘development communication’ into ‘community development’ and ‘adult education’ in terms of interests, views and theoretical backgrounds of these fields of social sciences; and to draw some implications for developing scholastic interactions among these fields to pursue common social changes of human society. Development communications provide opportunities to set goals, to decide contents, and to utilize communication media in developmental efforts. Contemporary trends of development communication, community development and adult education are concerned with indigenous, two-way, bottom-up and people-centered communication from exogenous, one-way, top-down and institution-centered communication of the past. Multidisciplinary approaches to communication concepts and methodology may increase the potentials of community development and adult education in terms of efficiency and effectiveness. Some of the development communication approaches such as traditional and folk media approach. new media or ICT(information & communication technology) approach, participatory communication for development approach, communication support development approach and mass media approach may be applicable for community development and adult education. Better understanding on development communication approaches will be needed for the adult educators as well as community development practitioners.

Purpose This study was conducted to identify the multidimensional role of institutional mechanisms in the linear relationship of satisfaction, trust and repurchase intention, which are used as an important concept in the research of e-commerce. To this end, a research model was proposed by combining concepts which are the concept of perceived effectiveness of institutional mechanisms for overall e-commerce environment(e.g., PEEIM) and the concep of perceived effectiveness of institutional structures(e.g., PEIS) of a specific marketplace based on the social cognitive theory. Design/methodology/approach This study was conducted by dividing the data into two groups to identify institutional mechanisms and trust-building relationships according to the institutional contexts inherent in e-commerce. The institutional contexts were set up for the top two online companies and the bottom two online companies according to the results of the open market brand assessment from 2018 to 2019 in South Korea. Findings The result of this study found that PEIS had a direct impact on trust in both high and low groups respectively whereas PEEIM presented different paradoxical results in high and low groups. In the relationship between the satisfaction and the trust in the vendor of the high group, PEEIM showed negative moderating effects but in the relationship between the trust and the repurchase intention of the low group PEEIM showed positive moderating effects.

Social innovation refers to activities that solve social problems by developing new ideas in cooperation with actors close to the field for the purpose of preserving the sustainability of society. In the field of social innovation, voices calling for a bottom-up method that starts with citizen participation are growing, and the need to improve public officials' awareness of social innovation and strengthen professionalism is being raised. In the era of Covid 19 and the 4th industrial revolution, digital literacy is being emphasized to us. In the field of social innovation, the need to strengthen social activities using digital media is growing. In this paper, an example of online social innovation project education based on the design thinking methodology was presented for public officials in Busan to improve their awareness of social innovation and secure expertise, and the effect of job competency reinforcement was statistically verified. As a result of statistical analysis, the average difference between the 'online communication' factor and the 'online empathy' factor was the largest, and it can be interpreted that digital literacy for social innovation has been strengthened.

This manuscript illustrates the dynamic response of nanoscale carbon nanotubes (CNTs) embedded in an elastic media under moving load using doublet mechanics theory, which not considered before. CNTs are modelled by Timoshenko beam theory (TBT) and a bottom to up modelling nano-mechanics is simulated by doublet mechanics theory to capture the size effect of CNTs. To explore the influence of the CNTs configurations on the dynamic behaviour, both armchair and zigzag configurations are considered. The governing equations of motion and the associated boundary conditions are obtained using the Hamiltonian principle. The Navier solution methodology is applied to obtain the solutions for both orientations. Free vibration and forced response under moving loads are considered. The accuracy of the developed procedure is verified by comparing the obtained results with available previous algorithms and good agreement is observed. Parametric studies are conducted to demonstrate effects of doublet length scale, CNTs configurations, moving load velocities as well as the elastic media parameters on the dynamic behaviours of CNTs. The developed procedure is supportive in the design and manufacturing of MEMS/NEMS made from CNTs.
