본 논문에서는 근거리무선 통신용 RF 모들을 구성하는 핵심 부품인 5.5GHz 대역의 발진기를 설계 제작하였다. NEC사의 잡음 특성이 우수한 HJ FET인 NE3210S01를 사용하여 위상잡음 특성을 개선하였고, 구현된 회로는 HP사의 회로 시뮬레이터인 ADS2002를 사용하여 설계 및 제작하였으며 발진기의 특성을 측정한 결과, 중심 주파수 5.5 GHz에서 출력전력이 10 ㏈m 그리고 2차 고조파 억압이 -31 ㏈c이며 중심 주파수 100 KHz offset에서 -98.83 ㏈c의 위상잡음 특성을 얻었다. 제작된 발진기는 근거리 무선 통신용 국부 발진기로 이용될 수 있다.

Purpose: This study aims to explore the experience of cross-cultural communication adaptation between local and expatriate employees at PT. XX Organizational culture in the company is the most important factor to helpemployees in the company to work efficiently and effectively in order to achieve company goals. Research design, data and methodology: The analysis methods used in this research are data reduction, data presentation, and drawing a conclusion. From this collaboration, the cultural adaptations arouse due to the challenges for workers who have to work together with different cultural backgrounds. The method used is qualitative with a case study approach. Data collection methods used is employee interviews at PT. XX with triangulation conducted on 2 expatriates and 2 local employees. Results: Studies show that successful management is highly dependent on employees adapting to local culture and work situations. This process rarely runs smoothly because the persons in intercultural interaction do not use the same language and the lack of adaptation.. Conclusions: . In order to maintain its existence, the company strives to expand its wings in the global market and establish partnerships to expand cooperation. PT. XX from South Korea cooperated with Krakatau Steel, a state-owned Indonesian company

이 글은 케이블 지역채널에 대한 해설 논평 금지의 문제점을 검토하고 그 대안을 제시했다. 특히 방송법상의 저널리즘 원리에 입각해, 특정 사안에 대한 지역채널의 해설과 논평을 금지한 방송통신위원회 규칙이 방송 저널리즘의 책무와 상충한다고 논했다. 지역채널의 해설 논평 기능을 금지한 현행 규제는 오히려 지역여론이 지역의 기득권 혹은 기존 질서에 순응하는 방향으로 흐르게 하는 부작용을 야기한다. 지자체 정책홍보 프로그램의 의무편성과 맞물려, 지역채널을 지자체 정부의 홍보도구로 전락시킬 위험도 안고 있다. 이에 따라 법제 개정을 통해 지역채널의 해설 논평 기능을 허용하되, 케이블 SO에게 지역 저널리즘 기관으로서의 책무와 조건을 부과하고 이를 충족하도록 촉진 지원하는 보완책을 병행하는 게 바람직하다고 제안했다.

지역신문이 처한 복합적 위기 상황에 대해 지역신문발전지원특별법에 의한 공적 지원이 시행되었다. 이 법안의 제정 목적은 지역신문의 발전기반을 조성하는 것에 그치지 않고 궁극적으로 여론 다양성을 보장하여 민주주의를 실현함에 있다. 이 연구에서는 공공재로서의 성격을 가지는 지역신문에 투입된 공적 지원이 제도적 평가와 함께 지역민, 즉 수용자의 여론 다양성 보장에 영향을 미치고 있는지, 또 이러한 공적 지원으로 인해 지역신문의 공익적 가치가 증대되고 있는지 고찰하고자 한다. 이를 위해 이 연구에서는 지역신문의 정기구독자 중 시민단체의 모니터 활동 참여자를 대상으로 심층인터뷰를 진행했다. 지난 3년 동안의 기금 지원에 대한 효과는 기사를 통한 지면의 개선이 가장 컸고 신문사 사원들과 독자들에게서도 인식의 변화가 있었다는 것이다. 기사의 다양성도 증가되었으나 취재비지원에 대해서는 긍정적 평가와 부정적 평가가 공존했고, 대체로 장기적 효과에 대해서는 회의적이었다. 결국 지역의 신문 수용자는 지역신문이 질적인 개선과 함께 여론 다양성 보장을 위해 기금 지원은 필요하나 수용자적 입장에서의 여론 다양성을 보장하는가에 대한 평가를 고려하고 기금 지원의 효율성을 높일 수 있는 방안이 마련돼야 한다는 입장이라 할 수 있다. 지역신문법에 대한 수용자 관점의 평가를 알아보는 것은 매우 중요한 의미를 지니는데, 한국사회에서 언론의 역할, 특히 지역 언론의 역할과 기능에 대한 책임을 지역 수용자가 요구할 수 있다는 것은 민주주의를 성장시킬 수 있는 동력이 되기 때문이다.

It is expected that per-user customized services are widely used in next generation Personal Communication Network. To provide personalized services for each call, per-user service profiles are frequently referenced and signaling traffic is considerably large. Since the service calls are requested from the places where user stays, we can expect that the traffic is localized. In this paper, we propose a new service profile replication scheme, named Follow-Me Replication with local Anchor (FMRA). By replicating user's service profile in a user-specific location area, local anchor of each region, the signaling traffic for call and mobility can be distributed to local network. We compared the performance of the FMRA with two typical schemes: Intelligent Network-based !Central scheme and IMT-2000 based full replication scheme, as we refer it to Follow-Me Replication Unconditional (FMRU). Performance results indicate that FMRA lies between Central and FMRU schemes according to call to mobility ratio, and we identified the efficient ranges of CMR for FMRA depending on the various network parameters.

In order to improve the edge segmentation effect of the level set image segmentation and avoid the influence of the initial contour on the level set method, a saliency level set image segmentation model based on local Renyi entropy is proposed. Firstly, the saliency map of the original image is extracted by using saliency detection algorithm. And the outline of the saliency map can be used to initialize the level set. Secondly, the local energy and edge energy of the image are obtained by using local Renyi entropy and Canny operator respectively. At the same time, new adaptive weight coefficient and boundary indication function are constructed. Finally, the local binary fitting energy model (LBF) as an external energy term is introduced. In this paper, the contrast experiments are implemented in different image database. The robustness of the proposed model for segmentation of images with intensity inhomogeneity and complicated edges is verified.

As a result of this study, the income generation effect generatded by regional universities for the region is KRW 130.6 billion (direct and indirect income effect KRW 90.9 billion, induced income effect KRW 39.6 billion). In addition, it is estimated that the effect of regional universities on inducing employment in the region is 2,145 per year. Unless quality jobs are secured, the outflow of population to the metropolitan area will accelerate, and the disappearance of local areas will emerge as a social problem in the near future. Considering the effect of local universities on the local economy revealed through the results of this study, that is, the income and job creation effects, the government will be able to prevent local extinction by providing bold financial support to local universities. If it is difficult to afford it with government finances alone, it can be solved by opening the door to universities for admission through donations, which many advanced countries are introducing..

This study is on the development of an engine monitoring system which can be applied not only for mid-size vessels but also small vessels less than 20 gross tonnage. Monitoring system consists of a set LMU(Local Monitoring Unit) that collect data from local machinery, a host computer that controls LMU and a stable communication system which adopts CSMA/CD protocol. The LMU is composed of 80C196KC microprocessor, which consists of CPU, digital input/output, analog input/output and communication module. Communication system between the host computer(compatible IBM PC) and LMUs is the multidrop configuration using RS-485 method and confirmed high performance communication by the aid of polling method as well as carrier sense multiple access with collision detection(CSMA/CD) protocol.

Local device-to-device (D2D) communication between two smart mobile devices is becoming increasingly popular. The first key step in starting a D2D communication is to discover and identify the remote target device to establish a link. However, existing device discovery mechanisms either require users to explicitly identify the ID of the target device or rely on inaccurate beamforming technology. This paper presents two novel device identification algorithms using a variety of embedded sensors. The algorithms only require that users to point two devices towards each other. This paper describes the algorithms, analyzes their accuracy using analytical models, and verifies the results using simulations.

Water consumption has grown at more than 2.5 times, comparing the past century. About 2.8 billion people live in river basins with some form of water deficit, because more than 75 % of the river flows are withdrawn for agriculture and other needs. Challenges faced by more and more countries in their struggle for economic and social development are increasingly related to water. This paper proposes a test of an effective local river field environment management solution. And describing a part of a pilot project for the ministry of water resources of Uzbekistan. Current work focused on direct action items of the existing project and describe an IoT routing based solution for local river field environment management solutions. Suggested technological decisions provided by needs and on-site testing results. The paper describes the backbone of IoT routing based river water resources management system.
