In this increasingly globalised and rapidly-changing world, the various challenges that can arise are also increasingly globalised and complex. These may range from economic, environmental, societal or even demographic challenges. Solutions should therefore be applicable world-wide, but they need to be properly adapted to the specifications and needs at the regional and country level. This implies that past models of centralised innovation can be progressively substituted by new approaches based on openness and strategic collaboration between the various players involved. There are various models of openness and collaboration in research, development and innovation creating scientific networks at different levels. This paper is designed in a way to present the concept of smart specialisation and clusters and how they are linked and contribute to the support of Smart Specialisation Strategy in the Asian countries. The following paragraphs describe how smart specialisation is applied and the importance of clusters in developing a S3 strategy. In addition, the status of cluster policies in Asia as well as the steps towards S3 are also presented. The status of cluster policies and their steps towards S3 policies in Asia are described. The approach of China to adopt S3 in their R&I policy is also presented. The scope of this paper, is to demonstrate the policy framework of cluster and S3 policies in the region of Asia and how they are applied. China has been further analysed as a case, since they are more active in applying such policies.

Recycling is receiving increasing social attention today as our nation begins to grapple with the significant problems caused by huge amount of municipal solid waste. The topic of recycling is not simple but extremely complicated. This study attempts to provide basic data and policy options for expanding and improving separated collection and recycling in public residential areas, through three case study of apartment housing areas in Taegu Metropolitan City. The main results of this study are summarized as follows. For the significant period of time, all three case areas had in common the extreme difficulty in establishing and operating the system of connecting public participation, collection and storage, transportation, and actual recycling of materials because of a variety of problems involved in this process. Both amounts of and prices for collected materials fluctuated considerably over time mainly due to monthly changes in recyclable home materials and the dynamic nature of recycling markets. Public questionnaire survey revealed the very high level of participation in separated collection, not only because almost all respondents well understood the necessity and importance of recycling, but because they also knew how to do separated collection. But overall activities were rated low and most respondents suggested the enlargement of public participation, the improvement of collection and storage facilities, and collection transportation networks. In particular, most respondents had little experience of using recycled Products and used mainly reproduced soap and bathroom tissue. Furthermore, they were considerably unsatisfied with low variety and quality of recycled products, their high prices and low availability in the market. Finally potential policy options and activities for improving separated collection and recycling are suggested.

This study introduces a novel approach to the differentiation of two phenomena, Asian Dust and haze, which are extremely difficult to distinguish based solely on comparisons of PM10 concentration, through use of the Optical Particle Counter (OPC), which simultaneously generates PM10, PM2.5 and PM1.0 concentration. In the case of Asian Dust, PM10 concentration rose to the exclusion of PM2.5 and PM1.0 concentration. The relative ratios of PM2.5 and PM1.0 concentration versus PM10 concentration were below 40%, which is consistent with the conclusion that Asian Dust, as a prime example of the coarse-particle phenomenon, only impacts PM10 concentration, not PM2.5 and PM1.0 concentration. In contrast, PM10, PM2.5 and PM1.0 concentration simultaneously increased with haze. The relative ratios of PM2.5 and PM1.0 concentration versus PM10 concentration were generally above 70%. In this case, PM1.0 concentration varies because a haze event consists of secondary aerosol in the fine-mode, and the relative ratios of PM10 and PM2.5 concentration remain intact as these values already subsume PM1.0 concentration. The sequential shift of the peaks in PM10, PM2.5 and PM1.0 concentrations also serve to individually track the transport of coarse-mode versus fine-mode aerosols. The distinction in the relative ratios of PM2.5 and PM1.0 concentration versus PM10 concentration in an Asian Dust versus a haze event, when collected on a national or global scale using OPC monitoring networks, provides realistic information on outbreaks and transport of Asian Dust and haze.

Objectives: Members of Korean Healthy Cities Partnership(KHCP) has increased rapidly since 2006 and adopted Active Living Environments(ALE) as common theme in 2015. Academic definition and categorization, needs assessment and operational planning for making active living environments were required from KHCP. Methods: Literatures review, survey to members of KHCP, specialist discussion and consultation with members of KHCP have been done from October of 2015 to February of 2016. Results: ALE included humane(social networks), physical and political resources. Three categories and 13 items for ALE were identified. Present actions among member cities were variable and especially immature in physical environments. Indicators for ALE were not secured stably. Requirements for policy and physical environmental approach and adolescent programme were high. Priority areas for education and technical assistance were master planning, guideline and case, program and policy development, partnership development, and networking among cities. Representative projects among member cities were somewhat different from ideal models. Conclusions: Policy and environmental approaches needs to be reinforeced systemically for members of KHCP including securing stable indicators. More education and technical assistance also needed sustainably.

수중 음파 센서 네트워크는 수종환경에서 재해방지, 환경 감시 시스템 등의 용도로 이용될 수 있다. 그러나 수중환경에서는 지상과는 다른 긴 전파 지연과 낮은 전송 속도, 제한된 대역폭파 같은 특성을 고려하여야 한다. 본 논문은 수중 음파 센서 네트워크에서 우선순위에 따라 슬롯이 각 노드에 맞게 할당되는 비경쟁방식의 슬롯 예약 구간을 통해 충돌 및 에너지 손실을 최소화하는 Priority Reservation MAC(PR-MAC) 프로토콜을 제안한다. 또한 성능을 평가하기 위해 수학적 분석 모델을 제시하고 그 결과로 충돌 확률, 충돌에 의한 에너지 소모량, 처리율, 채널 효율을 기존 프로토콜과 비교 평가하여 제안된 프로토콜의 우수성을 보인다.

본 연구는 지리정보시스템(GIS)을 이용한 분석 결과를 기존의 방식이 아닌 그린인프라적 관점에서 해석하여 결과를 도출하고, 이를 바탕으로 개발제한구역을 그린인프라 네트워크에 어떻게 활용하여 연결시키는 것이 바람직한지 알아봄으로써 개발제한구역의 활용가치를 밝혀보는데 목적이 있다. 본 연구의 결과로 개발제한구역에 대한 그린인프라 네트워크 구성의 적정성 측면에서, 공간구조와 주변지역과의 광역적 연결성 등을 바탕으로 한 결론은 다음과 같다. 첫째, 대전권 개발제한구역에서 가장 이슈가 되는 공간은 유성구에 존재하며, 이는 2000년대 초부터 시작된 주택개발을 위해 개발구역을 해제하면서 발생한 문제이다. 따라서 정확한 환경평가를 통해 개발제한구역을 추가로 해제할 것인지 아니면 녹지를 복원하여 그린인프라 네트워크 구성에 대한 새로운 방향을 제시할 것인지 정책적 판단이 필요하다. 둘째, 남북으로 연결되고 있는 대도시들의 축이 전체 충청권의 녹지축뿐만 아니라 대전권 개발제한구역과 주변지자체의 개발에도 영향을 미칠 것으로 판단되므로 이러한 경향을 반영한 개발제한구역 조정안을 마련할 필요성 있다. 셋째, 개발제한구역의 강력한 집행으로 인해 주변 도시들의 인접부에 개발 압력이 증가하는 추세이고, 이중 북쪽으로는 세종시 남쪽으로는 논산 쪽이 주요 개발 타겟이 될 것으로 판단되므로 이에 대한 대책을 수립할 필요가 있다. 넷째, 개발제한구역을 해제하거나 보전하는 양면적 접근보다 기존의 평가기준에 그린인프라적 가치를 추가하여 종합적인 광역계획과 연동된 방향설정이 필요할 것이다.

Wildfires have become increasingly common and intense in South Korea because of climate change, but few have recognized the catastrophic level of the problem. Given the significant impact of wildfires, emergency management stakeholders must have effective risk communication structures for rapidly responding to such phenomena and overcoming geographical difficulties. Despite the country spending billions of dollars to build a big databased early warning system, risk communication flow during the 2017 Gangneung wildfire was ineffective, thereby causing substantial economic, social, and environmental losses. To examine the patterns of information exchange in South Korea's risk communication networks and their structural characteristics during the wildfire, we conducted semantic and network analyses of real-time data collected from social media. The results showed that the inefficient flow of risk information prevented emergency responders from adequately assessing the emergency and protecting the population. This study provides new insights into effective risk communication responses to catastrophic events and methods of research on webometric approaches to emergency management.

부산시 환경소음수준의 연속적 측정이 가능한 소음자동측정 망의 합리적 설치 운영은 부산시의 정온한 환경구축 정책 수립을 위한 중요한 관건이 될 수 있다. 도시 내의 환경소음 수준은 지역 환경수준에 영향을 미치는 제반 요인들의 복합적 작용에 의하여 결정된다. 따라서 정확한 환경소음수준의 측정이 선결되어야만 올바른 환경소음 개선대책의 수립과 추진이 가능하다. 현재 국내에서는 환경소음 실태파악 및 소음저감정책 기초 자료의 확보를 위해 최근에 소음자동측정 망을 구축 중에 있다. 또한 소음측정 망이 설치 운영되는 지역의 경우 측정망 자료의 공개를 통하여 해당 지역의 환경소음 수준을 표시하고 있으나, 측정결과가 시민들이 느끼는 체감 소음을 제대로 반영하지 못하는 것으로 인식되고 있다. 가장 주된 논거는 측정 자료의 신뢰성 부족과 측정망의 불합리한 설치장소로 요약할 수 있다. 본 연구는 현재 부산시 지역에 설치되어 있는 8개 소음자동측정 망의 설치 운영실태 분석에 주안점을 두고 있다.

The purpose of this study is to propose a transit accessibility analysis method based on temporal variability of travel time. In this study, transit accessibility was defined in three levels (in transit route, spot and region unit) to present findings from different spatial scopes. Recently, Jeju special self-governing province reorganized bus system of the island. To compare transit accessibility before and after transit policy implementation, the reorganized bus system of Jeju special self-governing province was selected as a case study. This study used General Transit Feed Specification (GTFS) data format as storage public transit information, and calculated travel time using ArcGIS GTFS networks analysis tools. In the analysis of individual transit route level, we found the 3 types of accessibility changes which is increments, no significant changes and reductions and these results come from transit route change (number of transfer, distance change) rather than changes of vehicle interval. We found increases of inflow and outflow speed in most target spots and overall transit accessibility has been substantially improved in Jeju island. This study implies that accounting for temporal variability of travel time in accessibility analysis can result in more useful and sophisticated accessibility information in decision-making processes.
