Background: Superior hypogastric plexus block has been advocated as a useful technique for the treatment of cancer related pelvic pain. The aim of this study was to evaluate the effect of neurolytic trans-intervertebrodiscal superior hypogastric plexus block for pelvic cancer pain. Methods: Twenty-eight patients with gynecologic, colorectal or genitourinary cancer who suffered intractable pain were studied. We performed superior hypogastric plexus block by trans-intervertebrodiscal approach at L5/S1 level under the C-arm fluoroscopic guide unilaterally or bilaterally. Ten ml of 100% dehydrated alcohol was injected through each needle. We evaluated the change of visual analog pain score (VAS; 0~100 mm) and daily dose of oral morphine sulphate at the time of pre-block and 7 days after the block. Results: Fourteen patients (50%) had satisfactory pain relief (VAS<30) while five patients (18%) had moderate pain control (VAS 30~60). The remaining nine patients (32%) had mild or little pain relief (VAS>60) and their daily oral morphine doses were above 160 mg. Additional pain control method may be needed for those patients who received high dose of opioid before neurolytic block. Conclusions: We conclude trans-intervertebrodiscal neurolytic superior hypogastric plexus block was effective in relieving pelvic cancer pain. Neurolytic block, earlier stage, may provide better effects for more comfortable life at the end stage for cancer patients.

This paper presents an Interprocessor Communication Network(IPC net) in ATM switching system. In order to supply stable and independent path for processor communication, additional network i.e., Ethernet, is suggested. An Ethernet switch centered on Ethernet binds each processor into a work range. IPC net proposed in this paper assures end-to-end inter-processor connection, uniform 100Mbps Ethernet bandwidth and enhanced user cell throughput of ATM switch with minimum Ethernet supporting block integrated into ATM system

Determining storage locations of containers is an important issue for efficient operation of container terminals. This study assumes a storage yard with a horizontal layout in which blocks are laid out in parallel to the quay and trucks enter at the side of a block to deliver (receive) a container to (from) the yard crane. Various storage rules for determining storage locations of containers are introduced. Simulation studies are conducted for evaluating various rules. The following guidelines are derived from the result of our simulation study: when designing a block, consider a block configuration in which the longest gantry and the longest trolley travel times of rail-mounted gantry cranes (RMGCs) are similar; do not restrict the types of containers that can be stored in a storage area; if different roles are to be assigned to different storage areas, one possible way is to divide a bay into two areas so that some rows in the bay are allocated to inbound containers while the other rows in the same bay are allocated to outbound containers; reserve the space in bay unit for a high productivity of RMGCs but reserve the space in stack unit when the storage space is not enough; when the storage space is not sufficient, allocate storage location in a way of starting from the end and ending at the middle of a block; for reducing the travel distance of internal trucks, provide a higher priority to a block nearer to the berthing position of the corresponding vessel.

The purpose of this paper is to examine the dissolution process of Dongnae-bu Dongheon Block(東萊府 東軒 一廓) under the Rule of Japanese. The results of this study are summarized as follows. First, the space orgnization of Dongnae-bu Dongheon Block(東萊府 東軒 一廓) proved to be clear on the basis of Dongnae-bu Eupji(東萊府 邑誌), the ficture of Dongnae-bu(東萊府) and the Original Land Registration Map(地籍原圖) at the end of Joseon Dynasty. Second, the old government offices, as well as Chungsin-dang(忠信堂), were converted into the local government office for the sake of Japanese colonialism. Third, the old government office and its land were transferred to the banking system(金融組合) and the educational foundation(學校組合) in the interests of Japanese colonist. Finally, the transfer land of civilian industry association forced Mangmi-ru(望美樓) and Dokjin-daeamun(獨鎭大衙門) to remove to another site and the private lots-subdivision assisted space taking to pieces.

We have identified sodium benzanilide (Na-BA), sodium diphenyl amine (Na-DPA) and sodium deoxibenzoin (Na-DB) as very efficient initiators for the living anionic polymerization of HIC. It has a slow propagation rate with the additive function of chain end protection, offering in the process a perfect control over MW and MWD. The well-defined amphiphilic coil-rod, coil-rod-coil, and rod-coil-rod block-copolymers of PHIC and P2VP with controlled architecture have been synthesized for the first time with ${\sim}100\;%$ yields. The resulting block copolymers showed lamellar film, donuts, solid and hollow micelles, by simply varying the solvents and the block compositions.

In this paper, we develop the system which inspects the metal mask using area scan camera and belu type xy-table and introduce its inspection algorithm. Thes whole area of the metal mask is divides into several inspection block and the sixe of a inspection block is decided by FOV(Field of View). To compare with the camera image of each block, the reference image is made by gerber file. The ratation angle of the metal mask is calculated through the linear equation that is substituted two end points of horizontal boundary of a specific hole in a camera image for. To calculate the position error caused by belt type xy-table, hough-transform using the distances among the holes in two images os used. The center of the reference image is moved as much as the calculated position error to be coincide with the camera image ...

In Factory Automation(FA) used by Programmable Logic Controller(PLC), Ladder Diagram(LD) is the most widely utilized and plays an important role in industrial control system. But recently, the study about Sequential Function Chart(SFC) is performed actively. When we program by SFC, generally, we design one routine from start to end. This method is difficult to design block control system, and we often make mistakes. In this paper, we propose the method that we design block control system and we analysis the difference of the method used this paper from conventional method.

A linkage mechanism is a device to convert an input motion into a desired output motion. Traditional linkage mechanism designs are based on trial and error approaches so that size or shape changes of an original mechanism often result in improper results. In order to resolve these problems, an improved automatic mechanism synthesis method that determines the linkage type and dimensions by using an optimization method during the synthesis process has been proposed. For the synthesis, a planar linkage is modeled as a set of rigid blocks connected by zero-length translational springs with variable stiffness. In this study, the sizes of rigid blocks were also treated as design variables for more general linkage synthesis. The values of spring stiffness and the size of rigid block yielding a desired output motion at the end-effecter are found by using an optimization method.

In the TV manufacturing industry, a demand for chic design of TVs is increasing. As a reult of this trend in TV design, more curved surfaces in a TV cabinet are introduced, which enforces the use of fixers to combine a front cabinet with a TV main body. In this paper, we introduce a robot system for attaching various types of fixers to a TV cabinet. The developed system consists of three main blocks. The first one is the dispensing block, in which transferred cabinet is centered and UV adhesives are dispensed on the cabinet. The second one is the fixer attaching block, in which a cabinet is centered again and fixers are attached to pre-determined places on a cabinet by a robot with several end effectors. The last one is the UV hardening block, in which very strong ultraviolet rays are applied to the cabinet for attaching fixers tightly to the cabinet. The developed system is successfully adopted in a TV manufacturing process.
