In thin film silicon solar cells, p-i-n structure is adopted instead of p/n junction structure as in wafer-based Si solar cells. PECVD is the most widely used thin film deposition process for a-Si:H or ${\mu}c$-Si:H solar cells. Single-chamber PECVD system for a-Si:H solar cell manufacturing has the advantage of lower initial investment and maintenance cost for the equipment. However, in single-chamber PECVD system, doped and intrinsic layers are deposited in one plasma chamber, which inevitably impedes sharp dopant profiles at the interfaces due to the contamination from previous deposition process. The cross-contamination between layers is a serious drawback of single-chamber PECVD system. In this study, a new plasma process to solve the cross-contamination problem in a single-chamber PECVD system was suggested. In order to remove the deposited B inside of the plasma chamber during p-layer deposition, a high RF power was applied right after p-layer deposition with SiH4 gas off, which is then followed by i-layer, n-layer, and Ag top-electrode deposition without vacuum break. In addition to the p-i interface control, various interface control techniques such as FTO-glass pre-annealing in O2 environment to further reduce sheet resistance of FTO-glass, thin layer of TiO2 deposition to prevent H2 plasma reduction of FTO layer, and hydrogen plasma treatment prior to n-layer deposition, etc. were developed. The best initial solar cell efficiency using single-chamber PECVD system of 10.5% for test cell area of 0.2 $cm^2$ could be achieved by adopting various interface control methods.

Road Sink Phenomenon (RSP) is one of the major issues in South Korea. National and local governments are trying to develop effective preventive measures against the RSP. Developing the policy-oriented RSP management is most important to minimize possible losses induced by RSP. In this study, we employed the Futures Wheel (FW) method to derive influence factors for RSP management. FW method is widely used for predicting future social-environmental condition. In addition, RAND Corporation's method is used to derive potential strategic agenda based on derived influence factors by FW method. These derived strategic agenda can contribute to develop the policies related with RSP management.

Around the world, public access to information plays a crucial role in improving lives and facilitating development. People, technology, and information, which also represent common themes of i-Schools, are deemed relevant in adapting to these global challenges. The main purpose of this research is to identify the orientation of curriculums in LIS Schools in South Korea toward technology, information, and people for graduate schools of library and information science. This research also correlates the directions of the schools with the UN 2030 Agenda. Using the Wilson model, this study examines the orientation of courses offered. The result of classification and content analysis revealed that courses offered are leaning towards technology and information content. Courses reviewed in the light of developing knowledge and skills of information professionals to facilitate the fulfillment of global goals can make libraries more responsive to the changing times.

The wave of the 4th Industrial Revolution was announced by Schwab Klaus at the 2016 World Economic Forum in Davos, and prospects and measures with the future society in mind have been put in place. With the launch of the Moon Jae-in administration in May 2017, Korea has shifted all of its interest to Big Data, which is one of the most important features of the 4th Industrial Revolution. In this regard, this study focuses on the role of the public sector, explores related issues, and identifies an agenda for determining the demand for ways to foster Big Data ecosystem, from an objective perspective. Furthermore, this study seeks to establish priorities for key Big Data issues from various areas based on importance and urgency using a Delphi analysis. It also specifies the agenda by which Korea should exert national and social efforts based on these priorities in order to demonstrate the role of the public sector in reinforcing the Big Data ecosystem.

The impacts that AI and robotics systems can and will have on our everyday lives are already making themselves manifest. However, there is a lack of research on the ethical impacts and means for amelioration regarding AI and robotics within tourism and hospitality. Given the importance of designing technologies that cross national boundaries, and given that the tourism and hospitality industry is fundamentally predicated on multicultural interactions, this is an area of research and application that requires particular attention. Specifically, tourism and hospitality have a range of context-unique stakeholders that need to be accounted for in the salient design of AI systems is to be achieved. This paper adopts a stakeholder approach to develop the conceptual framework to centralize human values in designing and deploying AI and robotics systems in tourism and hospitality. The conceptual framework includes several layers - 'Human-human-AI' interaction level, direct and indirect stakeholders, and the macroenvironment. The ethical issues on each layer are outlined as well as some possible solutions to them. Additionally, the paper develops a research agenda on the topic.

Many studies have been conducted to assess the health effects of climate change in Korea. However, there has been a lack of consideration regarding how the results of these studies can be applied to relevant policies. The current study aims to examine research trends at the agenda-setting stage and to review future ways in which health-related adaptation to climate change can be addressed within national public health policy. A systematic review of previous studies of the health effects of climate change in Korea was conducted. Many studies have evaluated the effect of ambient temperature on health. A large number of studies have examined the effects on deaths and cardio-cerebrovascular diseases, but a limitation of these studies is that it is difficult to apply their findings to climate change adaptation policy in the health sector. Many infectious disease studies were also identified, but these mainly focused on malaria. Regarding climate change-related factors other than ambient temperature, studies of the health effects of these factors (with the exception of air pollution) are limited. In Korea, it can be concluded that studies conducted as part of the agenda-setting stage are insufficient, both because studies on the health effects of climate change have not ventured beyond defining the problem and because health adaptation to climate change has not been set as an important agenda item. In the future, the sharing and development of relevant databases is necessary. In addition, the priority of agenda items should be determined as part of a government initiative.

치위생학이 독립적인 학문으로서 전문성을 가지기 위해서는 연구의 세부영역이 확립되어야 한다. 따라서 본 연구는 국내 치위생학 관련 기관 중 대한치과위생사협회 및 그 산하단체를 대상으로 델파이 조사를 이용하여 연구의제를 수집하여 연구요구를 파악하고자 하였다. 델파이 조사는 대한치과위생사협회 및 산하단체 총 8개 기관의 기관장에게 유선으로 연구 목적을 설명하고 전자우편으로 델파이 설문지를 배포 및 수거하였다. 연구의제는 한국 치위생학 학문 분류와 미국 NDHRA의 분류를 이용하여 분류하였고, IBM SPSS를 이용하여 기관별 분류된 연구의제 수에 차이가 있는지 교차분석을 통해 확인하였다. 그 결과 총 316개의 연구의제가 수집되었다. 한국 치위생학 학문분류로 연구의제를 분류한 결과 '임상치위생(36.7%)'에 관련된 연구의제를 가장 많이 제안하였고, 기관별 유의한 차이가 있었다(p<0.001). 또 제시된 연구의제를 미국 NDHRA 분류로 분류한 결과 기관별 제시한 연구의제 수가 유의한 차이가 없었고(p=0.054), '건강증진 및 질병예방(27.8%)'에 관한 연구의제가 가장 많았다. '기초치위생'에 관련된 연구요구는 대한치위생(학)과교수협의회에서 높았고, '임상치위생'에 관련된 연구요구는 한국치위생학회, 대한치과위생학회, 한국치위생감염관리학회, 대한치과위생사협회 임상회에서 높았으며, '사회치위생'에 관련된 연구요구는 대한치과위생사협회, 한국치위생과학회, 대한치과위생사협회 보건회에서 높았다. 이상의 결과 각 기관에서는 창설 목적과 유사한 연구의제를 제시하였다. 그러나 유사학문과 비교해보았을 때, 국내 치위생학관련 전문기관들은 비교적 기관별로 뚜렷한 특성을 나타내지 못하고 있는 것으로 보인다. 즉, 치위생학 연구의 세부영역이 확립되기 위해서는 각 기관에서 치위생학 학문분류에 따른 특성을 뚜렷이 하고, 그에 맞는 연구의제를 제시해야 할 것이다. 또한 연구자들이 연구결과를 투고 시 본인의 연구영역을 미리 분류하게 하여 세부영역을 확립하게 해야 할 것이다.
