A configuration for radio-over-fiber transmission, with remote LO delivery from the central office, and a simple, cost-effective, base station solution is proposed. It is shown that using practically available components, and even with a fiber dispersion of 17 ㎰/nm/km, it is possible to transmit, without repeaters, bit rates of up to 622 Mbit/s for about 20 km at a bit-error rate of 10$\^$-9/, with 0㏈m laser power and a modest optical gain of 6㏈. By increasing the optical gain to 25 ㏈, the link length can be increased to ∼80 km.

Purpose: To investigate effect of Sweet Bee Venom on postpartum's De Quervain's Disease. Methods: We investigated 3 patients diagnosed as De Quervain's Disease. Sweet Bee Venom Herbal-acupuncture was used for treatment of De Quervain's Disease, once every two days, 5 times. Pain, satisfaction at treatment and function of wrist were measured with VNS, Baumgaertner's nine point scale and dynamometer. Results: Pain reduction, functional improvement, increased grip power were found out in cases treated with Sweet Bee Venom Herbal-acupuncture. In every cases, they represent high subjective satisfaction with treatment. Conclusion: Clinical results show that Sweet Bee Venom Herbal-acupuncture has a good analgesic effect in De Quervain's Disease.

Applying digital network technology for advanced nuclear plant requires deterministic communication for tight safety requirements, timely and reliable data delivery for operation-critical and mission-critical characteristics of nuclear plant. Communication protocols, such as IEEE 802/4 Token Bus, IEEE 802/5 Token Ring, FDDI, and ARCnet, which have deterministic communication capability are partially applied to several nuclear power plants. Although digital communication technologies have many advantages, it is necessary to consider the noise immunity from electromagnetic interference (EMI), electrical interference, impulse noise, and heat noise before selecting specific digital network technology for nuclear plant. In this paper, we consider the token frame loss and data frame loss rate due to the link error event, frame size, and link data rate in different protocols, and evaluate the possibility of failure to meet the hard real-time requirement in nuclear plant.

AC AT feeding method consists return circuits of electric train inserting in parallel between trolly line and feeding line and connecting neutral line to rail and FPW. Due to increasing train number, electric load at feeding system are increasing and collecting voltage of train are going down. To increase electric load and collecting voltage between trolly line and rail, the usefulness of new autotransformer are considered which variation of short impedance and change of line voltage is simulated with modified winding ratio of autotransformer from 1:1 to variable tab.

Wireless Sensor Network (WSN) is made up of a number of sensor nodes and base stations. Traffic flow in WSN appears self-similar due to its data delivery process, and this impacts queue length greatly and makes queuing delay worse. Active queue management can be designed to improve QoS performance for WSN. In this paper, we propose self-similar traffic rate estimating algorithm named Power-Law Moving Averaging (PLMA) to regulate packet marking probability. This algorithm improves the availability of the rate estimation algorithm under the self-similar traffic condition. Then, we propose an adaptive Proportional Integral algorithm (SSPI) based on the estimation of the Self-Similar traffic rate by PLMA. Simulation results show that SSPI can achieve lower queue length jitter and smaller setting time than PI.

상징은 하나의 이미지로서 어떤 각각의 요소들을 나타내며, 많은 사람들에게 은유적으로 전달하는 힘이 있다. 애니메이션에 있어서의 상징은 관객으로 하여금 갖게 하는 여러 이미지를 표상화 시켜줌으로서 다양한 해석을 주고 심리적으로 좀 더 깊은 의미를 전달하여 상징적 가치를 더해준다. 실질적으로 애니메이션에 있어서 상징에 관한 구체적인 연구방법은 많이 되어 있지 알다. 체코 애니메이터인 이지 바르타 작품에서 나타나는 상징 이미지 중 체코에 문화적 특성에 따라 나타나는 어둠의 상징에 대하여 기호학적 측면으로 접근을 하였다.

In this paper we propose an effective genetic algorithm for solving the integrated inventory and routing problem of supply chain composed of multi-warehouses and multi-retailers. Unlike extant studies dealing with integrated inventory and routing problem of supply chain, our model incorporates more realistic aspect such as positive inventory at the multi-warehouses under the assumption of inventory policy of power of two-replenishment-cycle. The objective is to determine replenishment intervals for the retailers and warehouses as well as the vehicles routes so that the total cost of delivery and inventory cost is minimized. A notable feature of our algorithm is that the procedure for evaluating the fitness of objective function has the computational complexity closing to linear function. Computational results show effectiveness of our algorithm.

Purpose: The purpose of this literature review was to describe the roles of advanced practice nurses related to advance directives. Methods: A comprehensive literature review was conducted utilizing Pubmed, Ovid, and CINAHL. The key words for search were 'advance directives', 'living wills', 'durable power of attorney', 'advanced practice nursing', 'advanced practice nurse', 'nurse practitioner', and 'nurse specialist'. Research articles published between January 1990 and September 2010 and written in English were included. Review papers and expert's opinion were excluded. Results: Five articles were yielded and analyzed. Among them, two focused on the advanced practice nurses' role during the process of advance directives. The other three presented the outcomes depending on the type of nurses' involvement in each health care delivery system. Conclusion: Recently, Korea established advance directives and expanded to diverse sites. Advanced practice nurses' role in the advance directive decision-making process should be examined and developed in research and practice.

In precision machinery industry, it's required with small size and low noise design to using in constant liquid delivery equipment. To accomplish it's purpose, we designed the check valve with rubber sheet of circle shapes as a possible assembly in pump body. The test equipment for piezoelectric pump was able to test pressure-flow property and output property of piezoelectric pump by variation(magnitude of voltage and frequency) of input power.
