The purpose of this study was to describe elementary school students' health communication needs based on school-based health fairs by students' demographic characteristics and school health education experiences. A self-administered survey was conducted to a total of 851 fifth-grade students in 8 elementary schools in Seoul. For survey participant sampling, Seoul area was divided into four districts: north, south, east, and west, and two elementary schools were selected from each district by the stratified convenient sampling process. Three class 5th-grade students in each selected school finished the survey. Questionnaires and survey instruction letters were delivered to vice-principals in the designated schools and the vice-principals managed the survey process. The survey Questionnaire included demographic characteristics (sex, parent's marital status, parents' educational status, famil financial status, the person whom was with after school, and daily computer hour), health education experiences (health education at school, and school health education satisfaction), and health communication types. The health communication types were reorganized into eight types based on comprehensive literature review on health fairs (or child and adolescence. The health communication types were 'health exam and advice fair,''health promotion advertising and campaign,' 'health-related exhibition and experience fair,' 'profession visit-in-school education,' 'health-related VCR or movie festival,' 'health-related institute visits,' 'internet health counseling,' and 'telephone health counseling.' Regarding demographic characteristics, sex, family financial status, and academic performance were significant factors related to health communication need scores (p <.05). Girl, high level of family financial status, and excellent academic performance score were related to high score of health communication need. In terms of school health education experience, taking regular class for health education and satisfaction with school health education were linked to higher health communication need scores. This result discusses that experience and satisfaction with school health education largely contribute to building participants' health communication concepts and needs.

Nowadays we does not hesitate to definite answer that the arbitration is the most developed dispute settlement out of court in the international commercial transaction. Online arbitration is desirable for the reasons of speed and cost effectiveness to settle the dispute about the international commercial transaction. Online arbitration is fast because it uses the communication technologies that allow information to be sent fast and efficiently. But in online arbitration too much speed and efficiency may lead to a violation of due process rights and consequently the online arbitration awards run a risk to be set aside or refused its enforcement under the international commercial arbitration mechanism. Speed and efficiency may conflict with the procedural guarantee characterizing each adversary dispute resolution process. As arbitration is exclusive of recourse to courts, a state must guarantee that arbitral proceeding should be satisfied with the claim rights requirement. The main question regarding the sources of regulation is particularly for the due process whether or not this is provided by the availability of grounds to set arbitral award aside. In other words, does it respect due process in the arbitration proceeding including information communication and technology under the online arbitration. In this paper it is discussed about how the main issue in arbitration should be implemented in online arbitration proceedings to cope with the due process requirements in national and international.

In this paper, an implementation of concurrent backoff delay process on a single chip with IEEE 802.15.4 hardware and 8051 processor core that can be used for analyzing the interference on IEEE 802.15.4 channels due to WiFi traffics is studied. The backoff delay process of IEEE 802.15.4 CSMA-CA algorithm is explained. The characteristics of random number generator, timer, and CCA register included in the single chip are described with their control procedure in order to implement the process. A concurrent backoff delay process to evaluate multiple IEEE 802.15.4 channels is proposed, and a method to service the associated tasks at sequentially ordered backoff delay events occurring on the channels is explained. For the implementation of the concurrent backoff delay process on a single chip IEEE 802.15.4 hardware, the elements for the single channel backoff delay process and their control procedure are used to be extended to multiple channels with little modification. The medium access delay on each channel, which is available after execution of the concurrent backoff delay process, is displayed on the LCD of an IEEE 802.15.4 channel analyzer. The experimental results show that we can easily identify the interference on IEEE 802.15.4 channels caused by WiFi traffics in comparison with the way displaying measured channel powers.

We studied a bilateral switching device for spin transfer torque (STT-MRAM) based on 3D device simulation. Metal/P/N+or Metal/N/P+ junction device with $30{\times}30nm2$ area which is composed of one side schottky junction at Metal/P/N+ and Metal/N/P+ provides sufficient bidirectional current flow to write data by a drain induced barrier lowering (DIBL). In this work, Junction device confirmed that write current is more than 30 uA at 2 V, It is also has high on-off ratio over 105 under read operation. Junction device has good process feasibility because metal material of junction device could have been replaced by bottom layer of MTJ. Therefore, additional process to fabricate two outer terminals is not need. so, it provides simple fabrication procedures. it is expected that Metal/P/N+ or Metal/N/P+ structure with one side schottky junction will be a promising switch device for beyond 30 nm STT-MRAM.

AlN is used a wide variety of applications such as electroacoustic devices, blue diode and metal-insulator-semiconductor structures. AlN thin films were deposited on Si substrates by rf sputter technique with low temperature process. The orientation and morphology of AlN thin films at various power in the range from 150 to 300 w was studied. X-ray diffraction (XRD), full width at half-maximum (FWHM) and field emission scanning electron microscopy were employed to characterize the deposited films. The c-axis orientation along (002) Plane at experimental results was enhanced with the increasing of the rf power from 150 to 300 w and the surface morphology of the films showed a homogeneous and nano-sized microstructure.

Traditional channel models for vehicle-to-vehicle (V2V) communication usually assume fixed velocity in static scattering environment. In the realistic scenarios, however, time-variant velocity for V2V results in non-stationary statistical properties of wireless channels. Dynamic scatterers with random velocities and directions have been always utilized to depict the non-stationary statistical properties of the channel. In this paper, a non-stationary geometry-based cooperative scattering channel model is proposed for multiple-input multiple-output (MIMO) V2V communication systems, where a birth-death process is used to capture the appearance and disappearance dynamic properties of moving scatterers that reflect the time-variant time correlation and Doppler spectrum characteristics. Moreover, our model has more straight and concise to study the impact of the vehicular traffic density on channel characteristics and thus avoid complicated procedure in deriving the analytical expressions of the channel parameters and functions. The numerical results validate our analysis and demonstrate that setting important parameters of our model can appropriately build up more purposeful measurement campaigns in the future.

The later part of the Lee-Dynasty was a period that marked an important turning point in the history of the modern communication system in our country. This paper proposes to research the historic process of initiation and development of the modern communication system in that period through the communication administrative organ and the installation of the wire communication lines such as wastward lines, southward lines and northward lines extended from Han Seung (Seoul) as well as the submarine cables from Korea to Japan. The modernization of the communication system in our country had been achieved in the struggle of national uprising spirits of Korean people against the invasive avarices of the neighbouring nations such as Japan and China. The initiation of the modern communication system played a leading role in civilizing our country. Thus the fair spirits of our forerunners who had schemed to develop the independent communication system should be valued enormously.
