Purpose : In order to study the effectiveness of East-West pain treatment on central poststroke pain(CPSP), we evaluated its effect on alleviation of pain and rehabilitation of CPSP Patients who were treated with electroacupuncture and west pain treatment for four weeks. Methods : Twenty four patients diagnosed by their pain characteristics of central pain from stroke were treated with sympathetic nerve block, gabapentin, amitriptyline, and electroacupuncture for four weeks. Pain intensity through the visual analogue scale(VAS), and improvements of mobility and rehabilitation through the modified Barthel index(MBI) and Rankin scale(RS), respectively, before and after pain treatment were also assessed. Results : VAS pain scores were significantly improved from 7.7±1.7 to 4.4±2.0 with pain treatment(p<0.05). In accordance with improvement of pain scores, RS and MBI scores were also improved from 2.88±0.95 to 2.13± 1.01 and from 83.0± 16.9 to 94.7±9.5(p<0.05), respectively, with pain treatment(p<0.05). Conclusions : It was suggested that the active pain treatment was contributed to the rehabilitation of CPSP patients, resulting in improvement of quality of life of CPSP patients. Futhermore, East pain treatment in combination with West pain treatment may be useful modality to alleviate CPSP.

In the real world, situations that some jobs need be processed only on certain limited machines frequently occur due to the capacity restrictions of machines such as tools, fixtures, or material handing equipment in this paper, we consider n-job, non-preemptive and m parallel machines scheduling problem having two machines group The objective function is to minimize the sum of earliness and tardiness with different release times and due dates The problems is formulated as a mixed integer programming problem The problem is proved to be NP-complete Thus, a heuristic is developed to solve this problem To illustrate its suitability and efficiency, a proposed heuristic is compared with a genetic algorithm and tabu search for a large number of randomly generated test problems in ship engine assembly shop Through the experimental results, it is showed that the proposed algorithm yields good solutions efficiently

Periosteum in general is described as a specialized fibrous membrane of mesenchymal origin consisting of two basis layers : outer fibrous layer consists of irregularly arranged dense connective-tissue with fibroblasts, and inner osteogenic or cambial layer is composed of more loosely arranged fibers, greater vascularity and flatted spindle-shaped pre-osteoblasts. This periosteum may serve in controlling bone growth, especially mandibular growth has been emphasized. But, the periosteum enwrapping the facial skeleton have been studied for many years leaving a controversy in opinion regarding the function of these structures. We evaluated the bone formation activity of te periosteum in allogeneic bone grafts which bones are made of freeze-dried preparation preoperatively. We made the calvarial bone defects, 5×7mm sized, amd grafted with allogeneic bone in rats, which a half of specimens has dissected the overlying periosteum and a rest intacted. After bone grafting, we evaluated the capacity ofbone formation of periosteum, 1, 2, 4, 6, 8 weeks postoperatively. There are subtle differences of bone formation during early healing period after demineralized allogeneic bone grafting between control groups with periosteum and experimental groups without periosteum.

In this paper, we consider an n-job, non-preemptive and identical parallel machine scheduling problem of minimizing the sum of earliness and tardiness with different release times and due dates. In the real world, this problem is more realistic than the problems that release times equal to zero or due dates are common. The problem is proved to be NP-complete. Thus, a heuristic is developed to solve this problem. To illustrate its suitability, a proposed heuristic is compared with a genetic algorithm for a large number of randomly generated test problems. computational results show the effectiveness and efficiency of proposed heuristic. In summary, the proposed heuristic provides good solutions than genetic algorithm when the problem size is large.

Dysfunction of the inferior alveolar nerve indicated by various degree of numbness of the lower lip and chin is one of the few drawbacks of mandibular osteotomy, especially Bilateral Sagittal Split Ramus Osteotomy(BSSRO) and genioplasty. Although it has been recorded throughout the history of this techniques, it is true etiology poorly understood. In this study, 22 consecutive patients under class III malocclusiion impression and undergoing orthognathic surgery(BSSRO only 11 case, BSSRO with genioplasty 11 case) were studied using 4 neurosensory test(static light touch, directional discrimination, two-point discrimination, pin pressure nociception) with post OP 1 week, 2 weeks,4 weeks, 8 weeks, 12 weeks, 24 weeks, On control group, 10 members without trauma and nerve damage history, nerve test was accomplished. We concluded majority of patients return of sensation during post operative 24 weeks. Althought immediate nerve deficit are 92.2%, 97.2% 88.9% these are recovered to 25%, 35.72%, 10.71% at 24 weeks. Nerve recovery rate increased prominently between post 4 weeks and 8 weeks. There is no statistically difference about neurosensory deficit among the chin area. Neurosensory deficit more severe when the BSSRO with genioplasty group than the only BSSRO group. Immediate neurosensory deficit is larger left side than right side but after 6 months, there is no significantly difference between left side and right side. Static light touch and pin pressure nociception are more sensitive method of neurosensory deficit than two point discrimination.

A Study was performed to evaluate the house rats as reservoir host of certain helminths which can provoke zoonotic infections in man. A total of 184 house rats captured from 14 different areas of southern Korea was examined for the detection of nematodes and cestodes. The results obtained were as follows: 1. The captured house rats consisted of 161 Rattus norvegicus (87.5%), 22 R.rattus rufescens (11.9%) and 1 unidentified species. 2. With one or more species of nematodes and cestodes, 64.1% of captured rats carried helminthic infections. Among them, R. norvegicus showed higher infection rate (58.7%) than 22. raffus rufescens (4.9%) 3. The infection rate of nematodes was 50.5% and that of cestodes was 23.4% in those captured rats. 4. The following 6 species were identified among 184 captured rats throughout the study: 1) Nematoda: Capittaria hepatica 10.9% Heterakis spumosa 36.4% Syphacia obvwlata 9.8% 2) Cestoda: Hymenolepis diminuta 7.6% Hymenolepis nana 8.7% Cysticercus fasciolaris 9.2% From the above results, it is considered that the house rats especially R. norvegicus seemed to play an important role as a reservoir host in those helminthic infectons of zoonotic nature in Korea.
