본 연구는 구미 전자산업클러스터의 진화과정을 분석하고 지역산업변화에 정부의 역할을 이해하는데 그 목적이 있다. 1990년대 초반까지 구미 산업단지는 수도권에 본사를 둔 대기업 분공장의 집적지로 구미지역에서의 산업연계가 미약했다. 그러나 최근 20년 동안 구미는 지역 내 기업 간 연계와 중소기업의 혁신활동이 상당히 이루어져 전자산업중심의 클러스터로 발전하고 있다. 정부의 산업정책은 구미전자산업클러스터의 진화과정을 이해하는데 매우 중요하다. 초기의 국가산업정책은 전략산업의 선정과 개발을 통해 구미 국가산업단지의 성장과 전자산업 중심의 전문화에 영향을 미쳤으며, 최근의 혁신클러스터 정책은 기업, 대학, 연구소간의 연계를 강화하고 지역 내 혁신네트워크 형성을 지원하였다. 경상북도와 구미시는 지역 대학 및 기업과 직접 협력관계를 맺고 지역의 연구개발 역량 향상과 중소기업 지원을 위한 정책을 중심으로 지역 발전에 기여하였다. 중앙정부와 대기업의 역할에 더해 지방정부와 중소기업의 역할 증대가 구미산업클러스터 진화의 기반이 되고 있다.

Purpose: The purpose of this study is to understand what kinds of chemical substances have been used annually and to investigate incidents that occurred due to chemical hazard release and to analyze statistically clinically chemical injury patients who visited one regional emergency medical center in Gumi city with documented references review. Methods: Annual chemical waste emission quantity (Kg/Year) (Cwep) was reproduced using national web site data governed by the Ministry of Environment and 5 years (from 1 .Jan. 2010 to 31. Dec. 2014) of medical records of chemical injury patients who visited our emergency department were reviewed retrospectively. By applying exclusion criteria, 446 patients of 460 patients were selected. Results: Dichloromethane, Toluene, Trichloroethylene, and Xylene were always included within Top 5 of Cweq. Six cases of chemical incidents were reported and in 3 of 6 cases involving Hydrogen fluoride were included during the study period. Male gender and twenties were the most prevalent group. Injury evoking chemicals were Hydrogen fluoride, unknown, complex chemicals (over 2 substances) in sequence. The most frequent site of wounds and injuries was the respiratory tract. Gas among status, intoxication among diagnosis, and discharge among disposition was most numerous in each group. Conclusion: There have been no uniform clinical protocols for chemical wounds and injuries due to various kinds of chemicophysical properties and ignorance of antidotes. Therefore conduct of a multicenter cohort study and experiments for ruling out chemicals according to chemicophysical priority as well as development of antidotes and clinical protocols for chemical injury patients is needed.

Purpose: The purpose of this study is to verify the influence of a massive hydrofluoric acid spill on community health through patients who claimed to have been exposed. Methods: We analyzed 2459 patients who visited our emergency department with the claim of exposure to hydrofluoric acid, and retrospective analyses were performed. We analyzed changes in numbers of visitors per day from the day of the accidental hydrofluoric acid spill, symptoms presented by the 1924 patients, and general characteristics. Comparisons of symptoms and hematologic characteristics were made between the initially set evacuation zone(1.3 km radius parameters from the spill) and the outer zone. Results: A total of 2,459 patients who claimed exposure visited our ED from 27 September 2012 to 23 October 2012, and there was a significant increase in the number of visiting patients from day 8 of the hydrofluoric acid spill. The most common complaints were a sore throat, 729(37.9%) and no specific symptom with health concern, 547 (28.4%). Statistically significant findings were pulmonary symptoms (p=0.001), nasal symptoms (p=0.001), diarrhea (p=0.023), and skin symptoms (p=0.007). In hematologic study, a statistically significant difference was observed in white blood cell count (p=0.018), creatine phosphokinase (p<0.001), erythrocyte sediment rate (p=0.013), and phosphorus (p<0.001). Conclusion: A significant increase in the number of patients was observed one week after the accidental spill of hydrofluoric acid. The most frequent symptoms were sore throat, headache, cough, and sputum. Statistically significant increase in creatine phosphokinase level and decrease in phosphorus level were noted in patients within the evacuation zone.

본 논문은 1960년대 말과 70년대 초기의 구미공단 조성과정을 다중스케일적 관점에서 분석하는 것을 목적으로 한다. 흔히 한국의 발전주의 시기 산업화 과정을 "발전주의 국가론"의 관점에서 분석하면서 국가 스케일의 정치-사회-경제적 과정에 주목하거나, 혹은 국가관료의 계획합리성에 입각하여 설명하는 경향이 있는데, 본 논문에서는 전략관계적 국가론과 다중스케일적 인식론을 바탕으로 이러한 관점을 비판하면서, 국가 안에서, 혹은 국가를 통해서, 작동하는 다양한 사회세력들이 다양한 공간적 스케일에서 복합적으로 서로 경합하고 타협하면서 산업화와 관련된 국가의 행위들이 결정되었다고 주장한다. 본 논문은 이러한 견해를 구미공단이 조성되던 과정에 대한 사례연구를 통해 실증적으로 밝힌다. 구미공단 조성과정은 전자산업을 육성하려는 국가관료들의 계획합리성에 의해서만 설명될 수 있는 것도 아니고, 박정희 대통령의 고향이라는 정치적 이유만으로 설명될 수 있는 것도 아니다. 국가의 정치지도자와 관료들의 역할뿐만 아니라, 구미지역에 장소의존적 이해를 가진 로컬 행위자들과 한국과 일본을 오가면서 활동하던 재일교포 사업가, 지역과 국가 스케일에 모두 연결된 지역구 국회의원 등 다중스케일적 행위자의 역할이 구미공단의 조성에 매우 중요한 영향을 주었음을 이 논문은 밝힌다.

Purpose : Myofascial decompression is frequently mentioned as a method applied to cupping. The purpose of this study is to evaluate and compare active range of motion (AROM), muscle strength, and functional movement by applying myofascial decompression to the hamstrings. Methods : This study evaluated AROM, muscle strength, and functional movement by applying active movement myofascial decompression and static myofascial decompression to the dominant leg, respectively, in a crossover design conducted with normal adults (n=21) in their average 20s enrolled at G University in G city, Gyeongsangbuk-do. Active movement myofascial decompression was implemented for five minutes at a rate of 100 bpm to make the beats in flexion and extension respectively. Static myofascial decompression was only performed for five minutes while at rest. All of these interventions were performed at a cupping depth of two mm. After a one-week washout period, static was applied again to compare the same dependent variables. Results : Regarding AROM and muscle strength, both groups showed significant differences in the before and after results (p<.05). However, in the Functional Reach Aspect and Single Leg Hop test, the active movement myofascial decompression group showed better results. There was no statistical difference between the Active movement myofascial decompression group and Static myofascial decompression group in any dependent variable (p<.05). Conclusion : As a result of this experiment, both active movement myofascial decompression and static myofascial decompression had a positive effect on dependent variable. Therefore this study is meaningful in that it is easier and simpler to see the effect on flexibility, muscle strength, and functional movement just by implementing movement myofascial decompression.

In order to improve ozone generation, we experimentally investigated the silent discharge plasma and ozone generation characteristics of a multi-discharge type ozonizer. Ozone in a multi-discharge type ozonizer is generated by superposition of a silent discharge plasma, which is simultaneously generated in separated discharge spaces. A multi-discharge type ozonizer is composed of three different kinds of superposed silent discharge type ozonizers, depending on the method of applying power to each electrode. We observed that the discharge period of the current pulse for a multi-discharge type ozonizer can be longer than that of silent discharge type ozonizer with two electrodes and one gap.Hence, ozone generation is improved up to 17185 ppm and 783 g/kwh for the superposed silent discharge type ozonizer for which an AC high voltages with a 180 phase difference were applied to the internal electrode and the external electrode, respectively, with the central electrode being ground

Purpose: This study was conducted to identify the characteristics associated with sulfuric acid injury in the emergency department. Methods: Data were collected retrospectively from January 2007 to December 2015 on all sulfuric acid injuries presenting to the emergency department in Gu-mi Soonchunhyung University Hospital. Patients injured by sulfuric acid were recorded over a nine year study period and collected data included demographics, injury mechanism, injured body part, hospital care and final diagnosis. Results: A total of 26 cases were identified. Most patients were male (88.5%) and the face was the most commonly injured body part. The most common mechanism of injury was splashing injury. A total of 16 (61.5%) patients were identified as having lesions worse than second degree burns. Conclusion: Sulfuric acid can cause severe and fatal skin burn. When working with sulfuric acid, acid proof protect clothing, goggles and glove should be worn. Furthermore, safety education and workplace environment improvement are necessary to reduce sulfuric acid injury.

In this study, a novel algorithm of the improvement residual non-uniformity (RNU) in thermal imaging system is proposed using correlated double sample signal processing. The proposed method attempts to eliminate offset variation of ROIC in IR detector causing the variation of FPA (focal plane array) temperature and suppling power. Experimental results show that the proposed method confirmed a better performance than the existing RNU system.
