This study is a case study focusing on the residents' participation and satisfaction in the promotion of rural development projects under the Block Grants System in Buyeo. Along with changes in the way to support rural development projects, it requires the autonomy, responsibility, creative planning etc. in the municipal governments and the active participation of local residents for the effective development in rural areas. The purpose of this study is to suggest some policy implications by analyzing the relationship between the level of participation of local residents and residents' satisfaction in rural development projects. This study explained the background and characteristics of rural development projects under the Block Grants System, and also reviewed the theoretical literature on the residents' participation and satisfaction, including the survey of the local residents. For this study, we selected some variables, and then divided into the participating groups such as the resident representatives, the development committee and the local residents. Finally, using statistical method we analyzed the level of participation and satisfaction of the local residents in rural areas.

Objective : The objective of this study was to determine which forms of iliac cancellous bone grafts better restore alveolar clefts. Study design : Forty consecutive patients who required a unilateral alveolar cleft graft were studied. Group I (20 patients) had reconstruction with iliac cancellous particulate bone grafts and group II (20 patients) had reconstruction with iliac cancellous block bone grafts. The two groups were evaluated radiographically and clinically. Results : The group with the block bone grafts showed less postoperative problems and better incorporation of the bone graft than the group with the particulate grafts. Conclusion : Surgical reconstruction of alveolar process defects in patients with alveolar cleft using iliac cancellous block bone is a more reliable method than particulate bone grafts both for closing the oronasal fistula and for building interalveolar septal height.

This paper deals with the procedures of effective mid-term Operation Planning establishment for painting shop in shipbuilding. and develop prototype system. In general, the block painting process consists of two stages such as blasting operation for surface preparation and painting operation for paint application for blocks. Weather condition is a potent Influence on those operations. The procedures consists of four steps, Load analysis, Generate alternative simulation plan. Implementation of Allocation automation module and Compare result of each simulation plan. Explain of each step. as follows, 1.step, Load analysis measure amount of assigned workload and manhour. 2.step, simulation scheme include alterable control variable such as overtime, weather. Auto allocating module carry out feasibility of simulation plan. 3.step, Allocation automation module are composed of three algorithms, as followings: - the block allocation algorithm that determines the number of blocks to be processed each day, - the team allocation algorithm that allocates blocks to worker groups. - the block arrangement algorithm that arrange blocks in blasting and painting cells. Since the block arrangement algorithm is conducted simultaneously with the team allocation algorithm, the total structure of the operating algorithms is considered to have two phases: first, daily load balancing with capacity limit and second, team allocation considering arrangement each day 4 step, Comparing result of each simulation plan. and select best simulation plan.

Background: Epidural steroid injections benefit certain patients with radicular pain, and often have only a limited duration. We compared the efficacy of hyaluronidase and triamcinolone and triamcinolone alone in patients with lumbar herniated disc disease treated with transforaminal epidural block. Methods: Forty patients who had undergone a transforaminal epidural injection were retrospectively reviewed. The T group received triamcinolone and local anesthetics; whereas, the HT group received hyaluronidase, triamcinolone and local anesthetics. We evaluated the improvement as being good, moderate, mild or no improvement, and in those where the improvement was good or moderate, also evaluated the duration of pain relief. Data were collected from the medical records of patients or via phone calls, which were analyzed using Student t- and chi-squared tests. A value of P < 0.05 was considered significant. Results: There were no significant differences in the degree of pain improvement or duration of pain relief between the two groups. Conclusions: A hyaluronidase and triamcinolone injection during transforaminal epidural block has on benefit with respect to the degree of pain improvement or its duration compared to a triamcinolone only injection.

Background: A motor blockade of lower limbs interferes with early ambulation and limits the usefulness of patient-controlled epidural analgesia (PCEA). The concentration of local anesthetic solution is a major determinant for motor block with PCEA. We compared the effects of epidural infusion of 0.075% ropivacaine with 0.15% epidural ropivacaine on postoperative analgesia, motor block of lower limbs, and other side effects. Methods: A total of 70 patients undergoing laparoscopic gynecologic surgery received epidural infusions (group R1, 0.15% ropivacaine with fentanyl; group R2, 0.075% ropivacaine with fentanyl). Pain score, motor block, and side effects (hypotension, nausea, vomiting, pruritus, urinary retention, dizziness, and numbness) were measured. Results: There were no significant differences in the demographic profiles between the groups. Pain scores of the group R1 and the group R2 were not significantly different. Motor block was more frequent in the group R1 (0.15% ropivacaine with fentanyl) than in the group R2 (0.075% ropivacaine with fentanyl). Conclusion: Lower concentration of ropivacaine (0.075%), when compared with higher concentration of ropivacaine (0.15%), seemed to provide similar analgesia with less motor blockade of the lower limbs for the purpose of PCEA.

Purpose: This study was to examine the effects of noise block on anxiety and vital sign of gynecologic laparoscopic surgery. Methods: The data were collected from March to May 2011. Participants were sixty patients with gynecologic laparoscopic surgery, divided into 30 of experimental group and 30 of control group at C University hospital located in I city. The day before surgery, demographic data, trait-state anxiety and vital signs were measured at ward. After noise block, the data were measured using VAS anxiety and vital signs before anesthesia and in recovery room. And then state anxiety and vital signs were measured in ward after surgery. The data were analyzed by $x^2$-test, t-test, repeated measured ANOVA and Bonferroni comparison method using SPSS/WIN 19.0. Results: After conducting noise block program, the experimental group showed significant decrease in state anxiety and heart rate compared to those of the control group. But there were not significant differences in VAS anxiety, systolic pressure and diastolic pressure between two groups. Conclusion: This program can be regarded as an effective nursing intervention for the management of anxiety with gynecologic laparoscopic surgery.

The impact of cardiovascular changes occurred by endotracheal intubation is risky for patients with ischemic heart disease, or intracranial pathologic conditions typically impairing cerebral autoregulatory mechanisms. Therefore, multiple approaches have been utilized to limit the impact of intubation and reduce damage of central nervous and cardiovascular systems. These approaches include modifications in intubation technique to diminish circulatory stimuli and pharmacologic modifications of either the sensory afferent path or the circulatory response itself. We tried the stellate ganglion block, a kind of sympathetic block, for the same purpose and evaluated the results. The results of study are as follows, 1) Blood pressure and heart rate increased significantly after intubation as compared with preintubation in both control group and SGB group. 2) The difference of the two groups is not found. We conclude the above method does not control cardiovascular consequences of endotracheal intubation.

Background: The purpose of this prospective randomized single-blind clinical trial was to evaluate the effect of tilting the head on the anesthetic efficacy of inferior alveolar nerve block (IANB) in patients with symptomatic irreversible pulpitis. Methods: Ninety-two patients were divided into two groups: the first group received IANB and the head was tilted in the direction of the block for 15 min, whereas the second group received IANB and the head was tilted to the opposite side. Access cavity preparation was initiated after 15 min. Success was defined as no pain or faint/weak/mild pain during endodontic access preparation and instrumentation. The anesthetic success rates were analyzed by Pearson chi-square test at 5% significance levels. Results: The same side position and opposite side position yielded 41% and 30% anesthetic success rates, respectively; there was no significant difference between the two sides. Conclusions: Relative head position has no effect on the anesthetic success rate of IANB.

This paper, wireless internet such as Wi-Fi has a vulnerability to security. Blockchain also means a 'Ledger' in which transaction information that occurs on a public or private network is encrypted and shared among the network participants. Blockchain maintains information integrity by making it impossible for a particular node to tamper with information arbitrarily, a feature that would result in changes in the overall blockchain hash value if any one transaction information that constitutes a block was changed. The complete sharing of information through a peer-to-peer network will also cripple hacking attempts from outside, targeting specialized nodes, and prepare for the "single point of failure" risk of the entire system being shut down. Due to the value of these Blockchain, various types of Blockchain are emerging, and related technology development efforts are also actively underway. Various business models such as public block chains such as Bitcoin, as well as private block chains that allow only certain authorized nodes to participate, or consortium block chains operated by a select few licensed groups, are being utilized. In terms of technological evolution, Blockchain also shows the potential to grow beyond cryptocurrency into an online platform that allows all kinds of transactions with the advent of 'Smart Contract'. By using Blockchain technology, the company makes suggestions to overcome the vulnerability of wireless Internet.
