본 연구는 개인차원에서 과업갈등과 직무태도 간의 관계에서 커뮤니케이션 만족의 매개효과를 밝히고자 하였다. 최근 급변하는 경쟁 환경과 다양해지는 인력다양성 상황에서 커뮤니케이션의 중요성은 날로 증대되고 있다. 조직 내에서 발생되는 커뮤니케이션에 대한 관심과 중요성 인식으로 인해 관련 연구가 활발히 진행되고 있다. 하지만 커뮤니케이션의 유형을 구분하여 커뮤니케이션의 긍정적인 메커니즘을 차별적으로 분석한 연구는 부족한 실정이다. 따라서 본 연구에서는 조직 내 커뮤니케이션의 대표적인 유형인 상사와의 커뮤니케이션과 동료와의 커뮤니케이션으로 구분하여 변수들 간의 관계를 살펴보고자 하였다. 다양화된 인적구성은 조직에 긍정적인 영향을 미치기도 하지만 대표적으로 갈등을 유발하는 요인으로 작용한다. 과업갈등의 경우 구성원들 간에 업무수행 과정에서 필연적으로 수반된다. 과업갈등의 경우 선행연구들에서 지속적으로 부정적인 영향력을 미치고 있으므로 조직관리적 측면에서 이를 제거하거나 감소시키기 위한 방안을 모색해야 한다. 과업을 수행하거나 과업 수행 중에 발생하는 갈등의 상황에서 구성원들은 자연스럽게 커뮤니케이션 과정을 거치게 된다. 이런 과정 속에서 만족감을 인식한다면 과업갈등의 부정적 영향력을 감소시킬 수 있을 것이다. 이를 규명하기 위해서 국내기업에 종사하는 280명의 조직구성원들을 대상으로 구조방정식모형(SEM)을 통해 가설을 검증하였다. 분석을 위해 SPSS 21.0 & AMOS 21.0 통계 패키지를 활용하였으며, 2개 이상의 매개효과를 효율적으로 검증하기 위해 팬텀변수를 활용한 다중매개효과 분석을 사용하였다. 분석결과 과업갈등은 직무태도에 부정적인 영향을 미쳤으며 상사소통의 매개효과가 검증되었다. 분석결과를 바탕으로 연구의 시사점과 향후 연구방향을 모색하였다.

The purpose of this paper is to know the effects on number and operation abilities of the 1st grade children of elementary school by applying teaching and learning activity throught communication. For this purpose, we have studied according to the following procedure. 1. We divised teaching and learning model through communication and applied in the actual teaching and learning activity. 2. We investigated the effects of number and operations abilities of the 1st grade children by applying teaching and learning activity through communication. To accomplish this purpose, we applied learning activity through communication to the 1st grade of 40 elementary school children for about six months(September 1, 1999 ～ February 20, 2000). In process of applying this model, we collected all sorts of cases in the children's learning activity and investigated children's response on learning activity through communication, interview with children and researcher's observation. We applied the model through communication in class and compared with the traditional learning. 1. In learning through communication, children could solve the problem in themselves with a sense of responsibility. 2. It was impossible to find out the degree of children's comprehension in the explanatory learning. But in the learning through communication, it was a great help to individualize and plan the learning because children express their ideas clearly. It has conclusion as follows. The learning activity through communication has effected on forming number and operations abilities of the 1st grade of elementary school children importantly. 1. Children have improved in the abilities through communication to express their own ideas. 2. Children have studied with a sense of responsibility not in the teacher-oriented learning but in the self-directed learning 3. Children could find out the mathematical concepts in themselves - correcting false concepts, reguiding concepts by errors, finding invisible errors, solving problems variously and knowing the easy method. 4. The activity through communication in mathematics was a base of children's individual learning and important data of next learning plan. 5. The mathematical concepts formed through communication had a high transfer of learning. 6. Children have taken pleasure of discovery and had affirmative attitude about mathematics learning. We can make sure that number and operations abilities of the 1st grade children are formed by applying teaching and learning activity through communication. However, help and control of teacher have to be with it.

Important network application services have been rapidly increased along with the growth of the Internet. So, it is desirable for such applications to serve transparently, continuously and safely even if the network is temporally disconnected or certain hosts running those services are crashed down. To satisfy such requirementes, many group communication systems have been developed; but, those systems restrict its range within a single LAN or directly interconnected LAN environments since the communication through the Internet is too slow and too unreliable to support group communication. As of now, it is expected the Internet is going to e sufficiently fast and reliable in the near communication system, named FACE(Java Advanced Communication Environment), supporting Extended Virtual which is a basic communication layer, RPGS(Reliable Process Group Service) which manages application process groups, and JACE API for developing Java application services and clients programs. In addition, an experimental replicated object space is developed as an application of the JACE system.

Substation automation is one of the key issues for the enhancement of the power industrial foundation. IEC 60850 is an international standard specifying communication network and systems in substation. It supports interchangeability and interoperability of equipments from different vendors. ACSI(Abstract communication service interface) specifies basic communication structure for substation and IEDs. It supports communication as well as various services without proper protocols. For actual communication, MMS(Manufacturing Message Specification : ISO 9506) is used to map ACSI services. Solutions for the development of communication driver based don IEC 61850 are proposed in this paper.

Visible light communication (VLC) is considered a strong future candidate for indoor wireless communication. However, its performance seems to be relatively unsatisfactory when compared to wireless local area network (WLAN) communication using millimeter waves. To improve the performance of VLC, numerous technologies have been proposed so far, in both electrical and optical domains. Among the proposals, optical beamforming (OB) is an optical-domain technology that can concentrate light in a specific direction or on a target spot. It can significantly improve VLC performance and can be widely used, because it does not depend on electrical modulation schemes. Therefore, this review discusses the concept, principle, and types of OB, the structure of a VLC system using OB, performance results of OB, and the combination of OB with electrical signal modulation in VLC. OB is expected to be one of the key techniques in future VLC implementations, similar to radio-frequency beamforming in millimeter-wave communication.

The semiconductor equipments generate necessary data through communication networks for the effective manufacturing processes and automation of semiconductor equipments. For transferring data between semiconductor equipments and sending data to monitor equipments, several standards for communication protocols have been proposed. Communication networks in semiconductor manufacturing systems will transmit a lot of data traffic, which can be vulnerable in data delay and network failure. Therefore, it is required that data traffic need to be distributed. To accomplish this objective, we recommend the use of a redundant and valuable communication path which is constructed by a wireless sensor network. In this paper, the directed diffusion method for wireless sensor networking is suggested for networking semiconductor equipments. It is shown that how the directed diffusion is employed to connect semiconductor equipments. Also, we show how to implement the SECS of semiconductor equipments communication protocols based on the directed diffusion.

The purpose of this study was to examine the effect that relation-building factors between beauty service stores and customers have on relationship quality and long-term orientation. Specifically, the influence of relation formation factors (relationship benefits and communication) on relationship quality (satisfaction and trust) and long-term orientation was empirically examined. This research was conducted through a questionnaire survey, and 402 adults were targeted from Jan. 6 to Jan. 16 in 2014. The results were as follows. First, the relationship benefits of beauty service stores were classified into four dimensions of psychological, social, economic, and informational benefits. It was found that only the dimension of psychological benefits had a significant influence on long-term orientation among the relationship benefits dimensions. Second, it was found that the psychological benefits of beauty service stores had positive effect on relationship quality (satisfaction and trust). It was shown that informational benefits had a significant influence on satisfaction only. Third, it appeared that communication had a positive effect on long-term orientation. Fourth, it was found that communication had a significant influence on relationship quality(satisfaction and trust). Finally, it was shown that relationship quality (satisfaction and trust) had positive effect on long-term orientation. The implications of the research and direction for future study were discussed.
