Angioaccess has become increasingly important to vascular surgeons as more patients with end stage renal disease[ESRD] are being supported by hemodialysis. Because of the rapid increase in the number of patients undergoing hemodialysis in recent years, it has become necessary to develope alternative vascular access procedures. During the period from December 1986 to December 1992, 290 cases of arteriovenous fistula and associated operations for hemodialysis were performed at Department of Thoracic & Cardiovascular Surgery, Seoul Paik Hospital, Inje University. They Consisited of 175 male and 115 female, ranging in age from 8 and 79 years. The procedure of first choice, the Brescia`s original radial artery-cephalic vein arteriovenous fistula was performed upon 219 patients. In many patients, the radial artery-cephalic vein fistula cannot be performed because of inadequate vein or failure of previous radial artery-cephalic vein fistula. The waiting time until initiation of venous puncture for the first hemodialysis session was 3 days. The second choice of angioaccess, using the brachiocephalic arteriovenous fistula and brachiobasilic arteriovenous fistula at antecubital fossa, ulnobasilic arteriovenous fistula, femorosaphenous arteriovenous fistula, and radiobasilic arteriovenous fistula with saphenous in situ routes, was obtained in 17, 7, 4, 2 and 1 patients. Interposition grafts, the third choice of angioaccess, were performed upon 2 patients. Twenty seven patients underwent revisions or thrombectomies. The purpose of this report is to review the technique of this procedure and discuss the longterm results.

The imidazopyridine, zolpidem, a non-benzodiazepine hypnotic drug, is widely-prescribed for insomnia. It is regarded as a good alternative to benzodiazepine because of the reduced possibility for abuse and development of dependence. However, more recently, due to the reduced possibility for abuse and development of dependence, it is regarded as a good alternative to benzodiazepine. adverse effects of zolpidem have been recognized. The objective of this report is to provide information on the potential for occurrence of benzodiazepine-like withdrawal seizure in patients who chronically take zolpidem continually. We present and discuss a case of seizure after sudden interruption of the protracted use of an abusively high dose of zolpidem. Zolpidem may not be the ideal drug for longterm pharmacotherapeutic management of insomnia. Clinicians should administer zolpidem at a low-dose for a short period of time for prevention of drug abuse and dependence and the potential for occurrence of benzodiazepine- like withdrawal seizure.

The susceptibility of radiata pine sapwood to fungal attack and the ability of selected fungicides to control colonization of sapstain and mold fungi on green radiata pine sapwood were evaluated. Radiata pine sapwood was highly susceptible to fungal staining, suggesting that prompt application of fungicides after sawing is essential for preventing fungal colonization. The ability of commercial fungicides to prevent fungal discoloration on radiata pine sapwood was assessed using an accelerated 6-week test on small samples in the laboratory, and in field tests using bulk-piled boards exposed outdoors for 6 weeks during summer rainy season. In laboratory tests, Hylite extra provided excellent protection against fungal discoloration even at the lowest concentrations. Hylite clear, Britewood S, and NP-1 Plus provided good short-term protection(2 to 4 weeks), but higher chemical loadings were, required for long-term protection(6 weeks). Woodguard produced little or no protection over the test periods. In field tests, Kathon 893 provided markedly superior protection at the concentration of 0.5 percent or higher. NP-1 Plus provided relatively good protection at all concentrations evaluated. Hylite extra was effective only for short-term protection(2 to 4 weeks) at all concentrations tested, but higher solution strengths were needed for longterm protection.

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.

Sludge is generated in the process of water and wastewater treatment, and it has been causing various problems environmentally and economically. The firing technology in pottery industry was applied to the sludge treatment, and the final product was called artificial soil. For the production of artificial soil, lime and chabazite was used as additive, and the mixed material was thermally treated in the firing kiln at $300^{\circ}$ temperature for about 15 minutes. The physico-chemical characteristics of the artificial soil was analyzed and it showed that the artificial soil could be used as a soil conditioner for farmland. The concentrations of the toxic heavy metals in the artificial soil were lower than those in the soil quality standard for farmland. It was high in permeability, total nitrogen and total phosphorous concentrations and surface area of the artificial soil compared to the common field soil. Preliminary cost analysis showed that the sludge treatment cost for artificial soil was less than the disposal cost in the current landfill disposal method. This study illustrated that the artificial soil production process can be a feasible alternative for sludge treatment, and produced artificial soil may he applied to farmland without causing significant adverse effect. Further study is recommended for practical application of the system and verification of the longterm effect of the artificial soil on farmland.

Management of laryngotracheal stenosis remains one of the most challenging problems facing the otolaryngologist. The key to success is to obtain adequate rigid circular support with normal mucosal lining. Four Patients with laryngotracheal stenosis were surgically treated in our institution in 2000. All the patients were male adults. The cause of stenosis were longterm or repeated endotracheal intubation and tracheostomy in our patients. All patients were successfully decannulated following segmental resection of the stenotic portion including the anterior arch of the cricoid cartilage and end-to-end anastomosis after suprahyoid laryngeal release. The time between treatment and decannulation was just one day in three patients. These results suggest the Possibility of early decannulation even if the cricoid cartilage was partially resected. It is better to prevent laryngotracheal stenosis rather than to treat it once it has occurred.

Purpose: This study was conducted to examine whether the level of classification for long-term care service under longterm care insurance reflects resource utilization level for residents in nursing homes. Methods: From 2 long-term care facilities, the researchers selected 95 participants and identified description and time of care services provided by nurses, certified caregivers, physical therapists and social workers during a 24-hr-period. Results: Resource utilization level was: 281.04 for level 1, 301.05 for level 2 and 270.87 for level 3. Resource utilization was not correlated with level. Differences in resource utilization within the same level were similar with the coefficient of variance, 22.7-27.1%. Physical function was the most influential factor on long-term care scores (r=.88, p<.001). The level for long-term care service did not reflect differences in resource utilization level of residents on long-term care insurance. Conclusion: The results of this study indicate that present grading for long-term care service needs to be reconsidered. Further study is needed to adjust the long-term care classification system to reflect the level of resource utilization for care recipients on the long-term care insurance.

Purpose - This study examines what are the asset market fluctuations in Europe and how each economic variable affects major variables, and explore the dynamics of housing and stock market through Greece. The variables under consideration are balance on current account (BCA), index of stock (STOCK), gross domestic product (GDP), housing price indices (HOUSING), M3, real rate of interest (IR_REAL) and household credits (LOAN). We investigate the functional and causal relationships between housing and stock market. Research design, data, and methodology - Vector error correction model (VECM) is used to figure out the dynamic relationships among variables. This study also contains the augmented Dickey-Fuller unit root, cointegration, Granger causality test, and impulse response function and variance decomposition analysis by EViews 11.0. Results - The statistical tests show that all variables under consideration have one unit root and there is a longterm equilibrium relationship among variables for Greece. GDP, IR_REAL, M3, STOCK and LOAN can be considered as causal factors to affect real estate market, while GDP, LOAN, M3, BCA and HOUSING can bring direct effects to stock market in Greece. Conclusions - It can be judged that the policy that affects the lending policy of financial institutions may be more effective than the indirect variable such as monetary interest rate.

We propose a simple and compact thyristor-based neuron circuit. The thyristor exhibits bi-stable characteristics that can mimic the action potential of the biological neuron, when it is switched between its OFF-state and ON-state with the help of assist circuit. In addition, a method of inter-neuron connection with synaptic devices is proposed, using double current mirror circuit. The circuit utilizes both short-term and long-term plasticity of the synaptic devices by flowing current through them and transferring it to the post-synaptic neuron. The double current mirror circuit is capable of shielding the pre-synaptic neuron from the post synaptic-neuron while transferring the signal through it, maintaining the synaptic conductance unaffected by the change in the input voltage of the post-synaptic neuron.
