The present conditions of Sanyangri village at Samcheok are stagnated and spiritless because there is only old men without young men. The purpose of this study is to make the basic plans of this rural and mountainous village to learn by personal experience. Therefore this study has been focused on its programs, land uses, roads and facilities how to activate it. The plan orientation of it is to make and become active by tourists to visit this village to experience the rural and mountainous living culture. So the general plan is divided into two zone which are the rural experience zone and the mountainous experience zone. Also the plan is to be considered to increase its amenities through the connection of surrounding villages and their resources. And it is necessary for the conversion as a tour place of sojourn and experience by supplying with various shows through connections with surrounding tour resources worthy of providing the various excitement through the visiting.

This paper presents the analyzed result of the series arc fault current by using the discrete wavelet transform. The series arcing is caused by a loose connection in series with the load circuit. The series arc current is limited to a moderate value by the resistance of the device connected to the circuit, such as an appliance or a lighting system. The amount of energy in the sparks from the series arcing is less than in the case of parallel arcing but only a few amps are enough to be a fire hazard. Therefore, it is hard to detect the distinctive difference between a normal current and a intermittent arc current. This paper, presents the variation of the ratio of peak values and RMS values of the series arc fault current, and proposes the novel series arc fault detecting method by using the discrete wavelet transform. Loads such as a CFL lamp, a vacuum cleaner, a personal computer, and a television, which has the very similar normal current with the arc current, were selected to confirm the novel method.

The key points of the CTP board is as follows: Film, brightness, plate exposure is eliminated, the reduction of personal expenses, and the reduction of time consumption. But above all, the accurate reappearance of the highlighting and shadow portion as well as self modification of the dust edge portion stands out as the most impressive improvements. In this paper, using a digital test from 4.0 and a Thermal CTP color printing control, the two parts of the Thermal CTP utilized a 1%-99% dot reappearance. Also, using an opposite line target, the results of the CTP plates and printing were compared. Finally, research was made on the printing quality on the slur development of the plate and the result when there was a lack of weave connection.

90년대 이후 계속해서 이동통신 기술은 발전에 발전을 거듭해왔다 1세대 아날로그 이동통신에서 2세대 디지털 이동통신 그리고 2.5세대라고 하는 PCS(Personal Communication Service)에 이어 3세대 이동통신의 혁명이라는 IMT2000 서비스가 눈앞으로 다가왔다. 1,2 세대 이동통신이 음성통학 위주의 서비스를 제공하였다면, 2.5세대에서는 소비자의 욕구가 음성통화를 벗어나 데이터서비스를 요구함에 따라 점차적으로 데이터 서비스에 대한 비중이 증가하게 되었다. 3세대 이동통신에서는 보다 빠르고, 보다 많은 데이터를 전송하기 위한 방안이 고려되었다. 본 논문에서는 2.5세대 이동통신에서 제공되는 데이터 서비스를 이용하여 GPS 모듈과 연동하여 물류단말기에 응용할 수 있는 소프트웨어 모듈을 구현하였다.

In this paper, we present a system which enables a real-time measurement of the number and also the body length of the fry (baby fish) using a line image sensor. Here, we consider a situation that fry are transported from a pond to another, pond through a pipe. At one position of the pipe a transparent rectanglar channel is mounted. The images of the fry, which run through this rectanglar channel, are detected by a line image sensor. The image signals are digitized to binary ones and the contour of the fry are detected. After that, a real-time image analysis is executed with a digital signal processor. Labeling program analyses the connection of every pixel. The results are transfered to a personal computer and displayed on the online monitor graphically.

This study was intended to identify customer's response to CRM of fashion business.488 questionnaires were distributed to male and female respondents aged 16 to 55, and then analyzed by descriptive statistics, oneway-ANOVA, chi-square test, and factor analysis. As a result of customer information management, respondents evaluated taste, interest and demographic informations as most valuable. But they did not value personal and credit information. For CRM concept, 4 factors were determined: continuous care and suggestion, particular service to important customer, customer management program development, and customer convenience consideration. For CRM activity, 3 factors were determined: customization, information offering, and programmed service strategies. Respondents were having positive attitude toward CRM concept and activity of fashion business. Among customer loyalty programs, they affected by immediate and direct programs most. The preference of customer contact methods was differentiated by sex and age groups. Males and teenagers preferred e-mail, and females preferred catalog and telephone connection.

In this paper, a smart constrained application protocol (CoAP)-based gateway with a border router is proposed for home safety services to remotely monitor the trespass, fire, and indoor air quality. The smart CoAP gateway controls a home safety sensor node with a pyroelectric infrared motion sensor, a fire sensor, a humidity and temperature sensor, and a non-dispersive infrared CO2 sensor and gathers sensing data from them. In addition, it can convert physical sensing data into understandable information and perform packet conversion as a border router for seamless connection between a low-power wireless personal area network (6LoWPAN) and the Internet (IPv6). Implementation and laboratory test results verify the feasibility of the smart CoAP gateway which especially can provide about 97.20% data throughput.

The IEEE 802.15.4 standard not only provides a maximum of seven guaranteed time slots (GTSs) for allocation within a superframe to support time-critical traffic, but also achieves ultralow complexity, cost, and power in low-rate and short-distance wireless personal area networks (WPANs). Real-time wireless body area sensor networks (WBASNs), as a special purpose WPAN, can perfectly use the IEEE 802. 15. 4 standard for its wireless connection. In this paper, we propose an adaptive GTS allocation scheme for real-time WBASN data transmissions with different priorities in consideration of low latency, fairness, and bandwidth utilization. The proposed GTS allocation scheme combines a weight-based priority assignment algorithm with an innovative starvation avoidance scheme. Simulation results show that the proposed method significantly outperforms the existing GTS implementation for the traditional IEEE 802.15.4 in terms of average delay, contention free period bandwidth utilization, and fairness.

In this study, we designed a model of NC controller with IBM-PC as a host CPU and intelligent servo controller for 2 axes that can be expaned to 4 axes. OS software was developed with C language at the base of mode selection technic for 9 NC operating modes. Servo controller design was based on the application of interpolator IC(3701) and position controller IC(3702) that permits low cost and high performance. For connection of two systems, parallel I/O communication was implemented. Finally, auto interpolation program test was executed for linear and circular paths resulting 1 LSB accuracy.
