Recently, TCO films with low carrier concentration, high mobility and high work function are proposed beneficial as front electrode in HIT solar cell due to free-carrier absorption in NIR wavelength region and low Schottky barrier height in the front TCO/a-Si:H(p) interface. We report high transmittance and work function zirconium-doped indium tin oxide (ITO:Zr) films with various plasma (Ar/O2 and Ar) conditions. The role of (Ar/O2) plasma was to enhance the work function of the ITO:Zr films whereas the pure Ar plasma based ITO:Zr showed good electrical properties. The RF magnetron sputtered ITO:Zr films with low resistivity and high transmittance were employed as front electrode in HIT solar cells, yield the best performance of 18.15% with an open-circuit voltage of 710 eV and current density of 34.63 mA/cm2. The high work function ITO:Zr films can be used to modify the front barrier height of HIT solar cell.

유선과 무선 등 다양한 융복합 기술을 이용하고 있는 컨테이너 항만에서는 작업을 위해 항만운영정보시스템(TOS)과 하역장비(CC, TC, YT) 간의 무선통신을 통해 작업정보를 교환한다. 그러나 컨테이너항만의 야드에 컨테이너화물이 높게 장치되어 있는 경우, 무선통신이 단절되어 음영지역(작업자가 정보를 받을 수 없는 지역)이 발생하여 작업 지연 및 작업 지시 오류가 발생한다. 이 때 작업자인 야드 트랙터(YT)의 운전자가 통신 상태를 인식할 수 있어야 한다. 그래야만 통신 음영지역에서의 작업 지연 및 작업지시 오류를 방지할 수 있고, 통신 단절로 작업이 지연될 때에도 작업자가 스스로 처리할 수 있다. 즉, 야드 트랙터에 장착된 웹-패드의 기능 개발, 그리고 통신 단절 시 빠르게 통신을 회복하는 기능 등을 개발하여 업무 처리속도를 향상시키는 등의 하역작업의 효율성을 높일 방안이 필요하다. 본 연구에서는 통신 모듈의 흐름을 변경하고, 야드 트랙터의 웹-패드에 단락(끊김) 또는 통신지연에 대한 네트워크 상태를 알려주는 UI 개발 등을 통해 작업자가 작업지연 및 작업지시 오류에 능동적으로 대처하여 하역작업의 효율성을 높이는 무선통신 환경을 구축하였다.

Recently, office workers are increasingly aware of the right to disconnect because of the pressure from strong connections with Internet messengers. In this study, we examined the reason why the perception of the right to disconnect increases and how to deal with it. This research model is that smart working and psychological attachment from work affect right to disconnect, and that open communication and gender moderate the intensity of these effects. To verify this research model, survey questionnaires were distributed to workers in smart working environments, and 400 data were collected and analyzed using Smart-PLS. As results of data analysis, it was verified that smart working and psychological attachment from work had a significant influence on right to disconnect, that open communication group had a lesser effect of psychological attachment from work on right to disconnect than closed communication group, and that women had a lesser effect of psychological attachment from work on right to disconnect than men. Organizations need to maintain a desirable level of right to disconnect in order to improve the quality of working life. But, if it is impossible, They need to change the way of communication more openly so as to absorb the burden of strong connection by Internet. And they need to perform task assignment or stress relief policy reflecting gender characteristics.

Scientific communication is an information exchange activity between scientists. Scientific communication is carried out in a variety of informal and formal ways. Basically, informal communication takes place by word of mouth, whereas formal communication occurs via the written word. Science is a highly interdependent activity in which each scientist builds upon the work of colleagues past and present. Consequently, science depends heavily on scientific communication. In this study, three mathematical models, namly Brillouin measure, logistic equation, and Markov chain are examined. These models provide one with a means of describing and predicting the behavior of scientific communication process. These mathematical models can be applied to construct quality filtering algorithms for subject literature which identify synthesized elements (authors, papers, and journals). Each suggests a different type of application. Quality filtering for authors can be useful to funding agencies in terms of identifying individuals doing the best work in a given area or subarea. Quality filtering with respect to papers can be useful in constructing information retrieval and dissemination systems for the community of scientists interested m the field. The quality filtering of journals can be a basis for the establishment of small quality libraries based on local interests in a variety of situations, ranging from the collection of an individual scientist or physician to research centers to developing countries. The objective of this study is to establish the theoretical framework for informetrics which is defined as the quantitative analysis of scientific communication, by investigating mathematical models of scientific communication.

We report high work function Aluminum doped zinc oxide (AZO) films as insertion layer as a function of O2 flow rate between transparent conducting oxides (TCO) and hydrogenated amorphous silicon oxide (a-SiOx:H) layer to improve open circuit voltage (Voc) and fill factor (FF) for high efficiency thin film solar cell. However, amorphous silicon (a-Si:H) solar cells exhibit poor fill factors due to a Schottky barrier like impedance at the interface between a-SiOx:H windows and TCO. The impedance is caused by an increasing mismatch between the work function of TCO and that of p-type a-SiOx:H. In this study, we report on the silicon thin film solar cell by using as insertion layer of O2 reactive AZO films between TCO and p-type a-SiOx:H. Significant efficiency enhancement was demonstrated by using high work-function layers (4.95 eV at O2=2 sccm) for engineering the work function at the key interfaces to raise FF as well as Voc. Therefore, we can be obtained the conversion efficiency of 7 % at 13mA/cm2 of the current density (Jsc) and 63.35 % of FF.

많은 기업들은 정보통신기술(ICT)을 이용하여 생산성을 향상시키고 있다. 이러한 정보통신기술의 사용은 자원기반 관점에서 주장하는 불확실한 환경에 대응한 기업의 경쟁우위를 창출하기 위한 하나의 과정으로 이해된다. 그러나 새로운 정보통신기술의 도입이 항상 업무 효율과 생산성 향상을 만들어내 것은 아니라, 오히려 새로운 정보통신기술의 도입이 기업 성과를 저해하는 요인으로 작용하는 경우도 있다. 테크노스트레스는 새로운 기술환경에 사용자가 적응하지 못할 때 사용자가 받게 되는 부작용을 의미한다. 즉, 새로운 정보통신기술의 이용에서 나타나는 부적 영향이 테크노스트레스라 할 수 있다. 이에 본 연구는 기업의 조직 구성원의 테크노스트레스가 반생산성에 미치는 영향을 규명하였다. 본 연구는 기존의 연구와는 달리, 대구지역 기업의 종사자들을 대상으로 연구를 수행하였으며, 혁신저항과 반생산적 과업행동을 종속변수로 활용하였다. 실증분석의 결과는 테크노스트레스가 반생산적 과업행동과 혁신저항을 증가시키고 있음을 나타내었다. 따라서 테크노스트레스가 생산성에 부정적으로 작용될 수 있기 때문에, 장기적이며 지속적인 경쟁력을 확보하기 위하여 새로운 정보통신기술의 도입을 준비하는 단계에서부터 조직 구성원들에 대한 체계적인 관리가 요구된다고 할 수 있겠다.

Building Ukraine as an independent, sovereign state requires the education of a citizen-patriot, able to live and work in a democracy, ensure the unity of Ukraine, feel constant responsibility for themselves, their people, country, seek to make a real contribution to the reform process. Modern modernization of the education system requires the search for new information and communication technologies that can ensure the formation of a citizen with an active civic position, which involves not only students mastering the rights and responsibilities of citizens, convincing them of the feasibility of democratic transformation of society, patriotic qualities and feelings, but also the identification of motivated civic actions. The pandemic and hostilities have led to significant changes in the field of education around the world, they have caused educational problems in Ukraine. At the beginning of the quarantine in the spring of 2020, all educational institutions in the emergency mode switched to distance learning. Intensive use of information and communication technologies in the life of modern society has led to a rethinking of the content of education and training of future professionals: the main role is played not so much by the information itself as the ability to work with it, critically comprehend and produce new knowledge; the main thing is not the amount of information, but its quality; information is needed for further practical application and transformation into knowledge, and the ability to work with information becomes one of the important competencies of the modern specialist in the new transformation of society: from information to the knowledge society. In this context, one of the main forms of training is distance learning, which is able to respond to the challenges of society. The main methodological positions that are taken into account in the construction of the structure and dynamics of the formation of civic responsibility of the individual during the use of information and communication technologies are highlighted. The structure of civil responsibility as a holistic system of information and communication technologies is outlined, which includes three subsystems that characterize the natural, social and systemic qualities of citizenship, interconnected hierarchically and synergistically.The constituent elements of the structural part of the model of civic culture of the individual are analyzed.
