In the current world, with the massive scale of SOC construction, it is difficult to diagnose and check all of a bridge's abnormal states with even the experts' eyes for maintenance. It is because we should spend huge costs and time on maintenance. Still, there are not many alternative ways to inspect bridges remotely regarding accuracy or reality. Therefore, we remark on the advantages and disadvantages of previous methods through practices in SOC maintenance. To inspect the abnormal state of the Bridge, we suggest inspecting bridges with an Augmented Reality (AR) mechanism to reduce cost, human resource consumption, and the risk of work. Through the proposed approach, we expect that it provides ways to solve massive construction problems with software-based technologies.

The objective of this study is to disclose the effect of socio-demographic characteristics such as, age and ethnicity which is comprised of Malay, Chinese, Indian and Others on four financial capability domains namely planning ahead, managing money, choosing products and staying informed. A closed ended self-administered questionnaire was disseminated to a total of 2000 respondents among four types of groups which consist of FELDA or rural area residents, private sector employees, government sector employees and youth in institutions of higher learning in Malaysia. Those four groups were selected to cover a wide range of Malaysian population. 500 respondents were involved in this study for each types of groups through purposive sampling technique. Analysis of Variance (ANOVA) and analysis via Statistical Package for Social Science (SPSS) was utilized in this study. The results revealed that age has significant effect on planning ahead, managing money, choosing products and staying informed. Whereas, ethnicities were found to have no effect on financial capability except planning ahead domain. It is suggested that more devotion should be placed on research and professional training in building respondents' financial capability. Furthermore, government and non-government organizations should develop a comprehensive approach to intensify their financial capability and upgrade their standards of living especially of financially vulnerable households.

현대적 관점의 디자인은 기업의 경제적 이윤창출을 목적으로 생산능률의 향상을 위한 디자인이나 판매 촉진을 위한 스타일링에 초점을 맞췄던 과거의 개념에서 변화하였다. '인간중심 디자인'으로 디자인이 시장과 자본의 원리뿐만 아니라 전통이나 문화에 적합한 인간 중심의 디자인, 문화중시의 디자인으로 나아가 사회적, 윤리적 책임과 가치가 함께 하는 디자인으로 향상되어 발전되어지고 있다. 이러한 현재의 디자인은 개인과 사회에서 만들어지고 습득된 문화에 기반을 두고 잠재되거나 표출된 사회적 가치를 중시하는 디자인의 결과물이며 이를 제공하는 디자이너의 책무로 여겨지기도 한다. 디자인의 사회적 영향에 대한 고려와 함께 검토되어야 하는 '디자인의 사회적 가치'실현을 위해 첫째, 소외되었으나 간과되어서는 안되는 이들을 위한 인간중심의 디자인과 둘째, 지역과 상황에 적합하며 지역사회 발전에 공헌하는 문화중심의 디자인과 셋째, 익숙한 아이디어들 선선한 패러다임으로 대체한 사용성 중심의 디자인에 대해 예시하였다. 이는 디자인이 갖는 가능과 의미를 목적적인 관점에서 제시하여 사회적 문제와 인간을 위한 방법을 디자인의 '문제의 발견'과 '문제해결 능력'에서 찾아 차후 사회적 가치의 실현과 확산에 대한 연구로 진행될 것이다.

한국 전력 계통의 가장 큰 문제점은 수도권의 부하 집중으로서, 서울과 경기도를 비롯한 수도권의 부하량은 전체 전력 소비량의 약 40%를 차지하는 반면 이들 지역의 발전량은 전체 전력 발전량의 약 16%에 불과하다. 이러한 수도권의 전력 수급에서의 불균형은 수도권이 아닌 다른 지역에서의 전력 전송을 필요로 한다. 이러한 장거리 전력 전송은 유효 전력에서의 손실 증대, 국지적인 무효 전력 불균형으로 인한 송전 용량 제한, 고장 용량의 증대 등을 일으키게 된다. 이를 해결하기 위해 고려할 수 있는 가장 간단한 방법은 수도권 내의 발전소 신설 또는 대용량 송전 선로의 추가 설치이다. 그러나 수도권은 과도한 인적 물적 자원의 밀집으로 인하여 대규모 발전소 및 송변전 설비의 건설을 위한 토지 조달 등에 어려움이 있고 또한 인구 밀집 지역에서는 공해와 같은 환경적 문제와 혐오 시설 기피 등의 사회적 문제로 인하여 현실적으로 발전소 또는 송 변전 설비의 건설은 불가능한 실정이다. 따라서 대규모 설비의 건설에 의한 문제 해결 보다는 기존 설비의 활용도를 증대시키는 방향으로의 접근법이 요구된다. 본 연구에서는 기존 송전 선로의 활용도 증대를 고려한 HVDC의 적용 방안을 개발하고자 하며, 이를 위한 시뮬레이션 모델의 개발 및 해석을 다루고 있다.

Objectives: Lung cancer is a major public health problem and one of the most costly illnesses. The study aimed to estimate the economic burden of lung cancer in Iran in 2014. Methods: A cross-sectional study was conducted to estimate the direct and indirect costs for patients with lung cancer using a prevalence-based approach. A human capital approach was employed to estimate the indirect costs. Data were obtained from several sources such as through patient interview using structured questionnaire, medical records, the GLOBOCAN databases, the Iranian Statistical Center, the Iranian Ministry of Cooperation, Labor and Social Welfare, and the Institute for Health Metrics and Evaluation (IHME). Results: The economic burden of lung cancer in Iran in the year 2014 was 3,225,998,555,090 IR. The main components of the cost were associated with mortality (81.9 %) and hospitalization (7.6 %). The costs of direct medical care, non-medical aspects, patient time, and mortality accounted for 10.8%, 2.7%, 4.5%, and 81.5% of the total cost, respectively. Conclusion: Findings from this study indicated that the economic burden of lung cancer is substantial both to Iran's health system and to society as a whole. Early diagnosis, strengthening cancer prevention, implementing new cancer therapy and medical technology, and effective smoking-cessation interventions could offset some of the costs associated with lung cancer in Iran.

How to compare the environmental damage caused by vehicles with different foe]s and drive trains\ulcorner This paper describes a methodology to assess the environmental impact of vehicles, using different approaches, and evaluating their benefits and limitations. Rating systems are analysed as tools to compare the environmental impact of vehicles, allowing decision makers to dedicate their financial and non-financial policies and support measures in function of the ecological damage. The paper is based on the "Clean Vehicles" research project, commissioned by the Brussels Capital Region via the BIM-IBGE (Brussels Institute for the Conservation of the Environment) (Van Mierlo et at., 2001). The VriJe Universiteit Brussel (ETEC) and the universite Libre do Bruxelles (CEESE) have jointly carried out the workprogramme. The most important results of this project are illustrated in this paper. First an overview of environmental, economical and technical characteristics of the different alternative fuels and drive trains is given. Afterward the basic principles to identify the environmental impact of cars are described. An outline of the considered emissions and their environmental impact leads to the definition of the calculation method, named Ecoscore. A rather simple and pragmatic approach would be stating that all alternative fuelled vehicles (LPG, CNG, EV, HEV, etc.) can be considered as ′clean′. Another basic approach is considering as ′clean′ all vehicles satisfying a stringent omission regulation like EURO IV or EEV. Such approaches however don′t tell anything about the real environmental damage of the vehicles. In the paper we describe "how should the environmental impact of vehicles be defined\ulcorner", including parameters affecting the emissions of vehicles and their influence on human beings and on the environment and "how could it be defined \ulcorner", taking into account the availability of accurate and reliable data. We take into account different damages (acid rain, photochemical air pollution, global warming. noise, etc.) and their impacts on several receptors like human beings (e.g., cancer, respiratory diseases, etc), ecosystems, or buildings. The presented methodology is based on a kind of Life Cycle Assessment (LCA) in which the contribution of all emissions to a certain damage are considered (e.g. using Exposure-Response damage function). The emissions will include oil extraction, transportation refinery, electricity production, distribution, (Well-to-Wheel approach), as well as the emission due to the production, use and dismantling of the vehicle (Cradle-to-Grave approach). The different damages will be normalized to be able to make a comparison. Hence a reference value (determined by the reference vehicle chosen) will be defined as a target value (the normalized value will thus measure a kind of Distance to Target). The contribution of the different normalized damages to a single value "Ecoscore" will be based on a panel weighting method. Some examples of the calculation of the Ecoscore for different alternative fuels and drive trains will be calculated as an illustration of the methodology.

Purpose - The purpose of this study was to analyze the effects of education & training and organizational culture on job satisfaction and organizational commitment and then examine the difference that would appear depending on the job title in the case of Korean employees in the manufacturing industry. Research design, data, and methodology - Our sample consisted of 1,013 administrative employees in the manufacturing industry with data extracted from the 4th Human Capital Corporate Panel (2011) survey. Descriptive statistics and multiple regression analysis were conducted. Results - Results showed that education & training had positive effect only on job satisfaction while organizational culture had positive effect on both job satisfaction and organizational commitment. Components under education & training (duration of the formal learning, efficacy of formal learning and efficacy of informal learning) and organizational culture (equity, communication, talent recognition, innovation) that were found to be affecting job satisfaction and organizational commitment revealed to be different depending on the hierarchical position of the employee. Conclusions - Different approach and policy for each group of job title could be considered in order to increase job satisfaction and enhance organizational commitment of the employees.

Tax is the main revenue of Government, so fighting tax evasion and sustainable growth have been the primary macroeconomic goals being pursued by every developing country, Vietnam included. The existence and development of the shadow economic sector are synonymous with the national budget losing out. In Vietnam, foreign direct investment projects do not promote economic growth and is also a sector that gives way to tax evasion.The purpose of this study is to investigate the impact of foreign direct investment, the quality of the informal institution on the size of the shadow economy in Vietnam, during the period 1991-2015. By applying the Autoregressive Distributed Lag approach and Toda and Yamamoto test, we found evidence to conclude that the quality of the informal institution harms the size of the shadow economy. The results of the causality test show that there is a unidirectional causality running from the shadow economy and the quality of the informal institution to foreign direct investment attraction in Vietnam. Political solutions need to be implemented carefully to counter the harmful effects of the shadow economy. Policymakers should adopt several economic policies to improve the 'human capital' and drive the shadow economy into the formal economy.

Variation in demand, natural resource availability, and technological advancement within a country are the main reasons for necessitating export and import activities between nations. Accordingly, this paper aims to analyze the effect of economic openness on Multifactor Productivity (MFP) in selected Asian countries (Vietnam, Thailand, The Philippines, Indonesia, Cambodia, China, Japan, Malaysia, South Korea, and Singapore) based on data for the period 1990-2018. The analysis conducted in the study employed the panel ARDL approach based on the estimation by Pooled Mean Group (PMG), Mean Group (MG), and Dynamic Fixed Effect (DFE). The Hausman test conducted indicates that the PMG estimation is better than that of MG and DFE since it has a higher variability value than the significance value. The results revealed that economic openness is able to elicit significant and positive effects on short-term and long-term MFP growth. In addition, the study established that other variable, such as the number of schooling years, are also able to produce a positive and significant effect on MFP growth in the long term. Since economic openness can impact MFP growth, every country should thus increase its export activities through more capital and worker inputs that will stimulate greater production.
