  • 2011년에 촉발되어 전 세계 20여 건에 이르는 Apple과 Samsung의 특허분쟁은 경쟁적 기술전략의 첨예한 양상을 보여준 대표적 사례이다. 두 기업 간 특허소송은 스마트폰 시장에서의 치열한 경쟁구조를 잘 보여준다. 반면, 두 기업은 ICT 및 하이테크 시장 선두기업으로서의 서로 긴밀한 협력적 관계에 있다. 그러나 기존 연구들은 경쟁 또는 협력의 한 부분만을 고려한 나머지 실제 기술경영의 현상을 제대로 진단하지 못했을 뿐 아니라 어떠한 패턴을 보이면서 진화하는지 규명하지 못하였다. 이에 본 연구는 경쟁-협력 동시적 공존의 코피티션(Coopetition) 산업생태계를, Apple과 Samsung의 스마트폰 분쟁사례를 중심으로 분석하고 그 함의와 방향성을 도출하고자 한다. 경쟁관점에서는 두 기업 간 소송자료 및 일지를 활용하여 분쟁의 흐름을, 협력관점에서는 소송에서 쟁점이 된 특허들의 인용정보를 활용하여 핵심기술을 구성하는 지식의 경향과 이전방향을 네트워크 분석방법론을 통해 분석한다.

  • Global climate change and urbanization have various demerits, such as water pollution, flood damage, and deterioration of water circulation. Thus, attention is drawn to Nature-based Solution (NbS) that solve environmental problems in ways that imitate nature. Among the NbS, urban wetlands are facilities that perform functions, such as removing pollutants from a city, improving water circulation, and providing ecological habitats, by strengthening original natural wetland pillars. Frequent monitoring and maintenance are essential for urban wetlands to maintain their performance; therefore, there is a need to apply the Internet of Things (IoT) technology to wetland monitoring. Therefore, in this study, we attempted to develop a real-time wetland monitoring device and interface. Temperature, water temperature, humidity, soil humidity, PM1, PM2.5, and PM10 were measured, and the measurements were taken at 10-minute intervals for three days in both indoor and wetland. Sensors suitable for conditions that needed to be measured and an Arduino MEGA 2560 were connected to enable sensing, and communication modules were connected to transmit data to real-time databases. The transmitted data were displayed on a developed web page. The data measured to verify the monitoring device were compared with data from the Korea meteorological administration and the Korea environment corporation, and the output and upward or downward trend were similar. Moreover, findings from a related patent search indicated that there are a minimal number of instances where information and communication technology (ICT) has been applied in wetland contexts. Hence, it is essential to consider further research, development, and implementation of ICT to address this gap. The results of this study could be the basis for time-series data analysis research using automation, machine learning, or deep learning in urban wetland maintenance.

  • This study aimed to provide data for establishment of resource management system of Iriomote Island in Okinawa Japan. Nature resource management system of Iriomote Island can be categorized into eight stages which are equivalent to regional development stages. 1) Networking among local people, tourists, researchers, tour operators and government authorities enhanced collection of resource data. 2) On the early stage, resource data were available only to researchers and government authorities. From the third stage of this system, however, local people were also involved in resource investigation, so they became to well recognize the values of their local resources. 3) On the sixth stage, data on unfamiliar local resources and attractions became to be known to people by real-time data collection and data provision services. The tourist number gradually increased and their visitation patterns were dispersed into different sites and seasons. In addition, some tourists also participated in resource investigation and they were likely to visit the place again. 4) To achieve successful ecotourism development, it is necessary to establish a management system with a feed-back process to identify, evaluate, use and protect the resources.

  • The term sustainable development is being used widely since WCED suggested it in 1987. This paper aims at catching up its sociological implications. For doing this, the paper examined some major existing researches on sustainable development. It was found that sustainable development has been defined as an economic development with the preservation of nature as an environment of human life. In this sense, the existing concept of sustainable development is an economic perspective. Sustainable development as an economic perspective is faced with some limitations and/or problems. They are summarized as follows. The human-made environment is excluded from the concept of sustainable development. Its ideology is anthroponcentric in that the sustainability of nature is a necessary condition for economic development. The objective reference which can measure whether the current state of nature is sustainable or not is not proposed. Consequently, sustainable development results in merely a survivability of economy, a new form of economic utility and/or a successful economy. In terms of sociological perspective, economy and nature can not be sustainable without other social factors being sustainable, because all social factors including economy and nature exist in a causal mechanism. This means that sustainable development should be approached from a multi-dimensional perspective. The multi-dimensional approach can be a framework of sustainable development in terms of whole society, then can be termed sustainable society which implies not a sustainable development, but a societal development. The factors which should be included in the sustainable society are, at least, nature, economy, population as an aggregate, mode of living existence of people as a cultural actor, technology, and social structure.

  • In response to epoch-making development in science and technology, the innovative curricular materials have been begun to develop since the late 1950s and early 1960s. However, the new inquiry-centered materials have failed to be successfully used in teaching/learning practices of science. Among the various reasons for the failure, the very nature of the inquiry approach has been identified as the most critical problem. Nevertheless, fostering inquiry faculties on the part of the students has been emphasized as one of the most important objectives of science instruction. Therefore this study was conducted for the purpose of developing a practical inquiry-oriented instructional method. In order to obtain this goal the nature of scientific inquiry was analyzed and the status quo of science education in which inquiry-oriented instructional strategies were applied was examined. The results of the study are described in this paper.

  • With the widespread use of smartphones and the development of information technology, an online service called SNS(social network service) has emerged, and as an increasing number of people began to use SNS, extensive research has been conducted on SNS. SNS is an important factor for adolescents who are developing social skills that help them to adapt to the society, and for adults who are stepping into the society. The present study investigates the effects of information search, self-disclosure, interaction, and playfulness, all of which are motivational factors for SNS use, on flow in SNS, and empirically analyzes the degree of these variables influence according to flow in SNS and individual's personal nature(extrovert, introvert). The analysis results showed that information search, self-disclosure, interaction, and playfulness were positively correlated with flow in SNS, and flow in SNS was positively correlated with social skills. The degree of influence varied depending on the individual's personal nature(extrovert, introvert). These findings may provide important insights for researchers studying SNS, SNS managers, and company officials using SNS.

  • Hospice movement in Taiwan emerged early in 1983. There was a nurse visiting terminal cancer patients by herself in Taipei city. It was ceased after one year. This stage of hospice movement might be called as "compassionate era". In early 1990, the first in-patient hospice ward was set up in north Taiwan. She demonstrated high touch in the high technology medical atmosphere. There was a great echo in Taiwan society to this action. In the following years, quite a few new hospice settings were founded. Medical professionals were aroused again to talk and think about life and death, dignity of dying and holistic care. This stage of hospice movement might be called as "ethical stage". Around 2000, obstructions were discovered in our development. We do need system and rules. Standard of setting and care, Curriculum of education and training, Accreditation system and specialist system and Nature Death Act are some of the systems we approached. This stage of hospice movement might be called as "Act stage". Among the "Act stage", the Nature Death Act is actually the mile stone in our history. What listed below are the translated one for the reference:
