Purpose : This study was conducted to analyze the job stress factors affecting the job satisfaction and job involvement of physical therapists and to provide basic information for the prevention of job stress among physical therapists. Method : One hundred and eighty-four physical therapists working in hospitals participated in the study by completing the Korean Occupational Stress Scale and surveys about job satisfaction and job involvement. The results were collected and analyzed. Result : The job stress factors the significantly influenced job satisfaction are the following, in order of importance: the organizational climate (p<.05), inter-personal conflict (p<.01), insufficient job control (p<.001), lack of reward (p<.001), and the occupational system (p<.001). The following factors significantly influenced job involvement, again in order of importance: job demand (p<.001), the organizational climate (p<.05), lack of reward (p<.05), the occupational system (p<.01), and insufficient job control (p<.001). Conclusion : The purpose of this study was to analyze the job stress factors affecting the job satisfaction and job involvement of physical therapists and to provide basic information to prevent job stress among physical therapists. The results indicate the need for more studies that analyze the job stress factors of physical therapists and additional studies that specifically analyze the tasks of physical therapists. Studies on how to reduce job stress among physical therapists must also be conducted in the future.

박승규 ( Seungkyu Park ),김종윤 ( Jongyun Kim ),조완구 ( Wangoo Cho ) 대한화장품학회 2004 대한화장품학회지 Vol.30 No.3

주형합성법을 이용하여 메조기공(mesoporous pore)을 지닌 나노실리카 물질들과 나노카본볼의 대량생산법이 개발되었다. 암모니아, 트리메틸아민, 아세트알데히드 그리고 메틸메르캅탄과 같은 악취 물질들이 마크로기공 코어-메조기공 쉘(macro-porous core/mesoporous shell) 구조체인 나노카본볼에 흡착되는 현상이 상업용 탈취제인 활성탄과 비교 조사되었다. 나노카본볼에서의 악취의 흡착 및 분해는 활성탄에 비해 우수하게 관측되었고 촉매가 나노카본볼 내부에 첨착되면 더욱 악취 분해 특성이 증가되었다. 나노카본볼의 우수한 흡착 및 분해 특성을 이해하기 위해 물리화학적 특성인 균일한 기공, 넓은 표면적, 큰 기공 부피에 관한 기공 특성과 악취의 분해 현상이 연구되었다. 이러한 나노카본볼은 탈취제 분야에서 많은 응용성이 있을 것으로 전망된다. Nano silica ball and nano carbon ball are developed commercially by template synthesis method. Adsorption of unpleasant smelling substances such as ammonia, trimethylamine, acetaldehyde and methyl mercaptane onto nano carbon ball with hollow macroporous core/mesoporous shell structures, nano carbon ball, was investigated and compared with that onto odor adsorbent materials, activated carbon, commercially available. The adsorption and decomposition of malodor at nano carbon ball exhibited superior than those onto activated carbon. The physicochemical properties such as mesopore size distributions, large nitrogen BET specific surface area and large pore volume and decomposition of malodor were studied to interpret the predominant adsorption performance. The nano carbon ball is expected to be useful in many applications such as deodorizers, adsorbent of pollutants.

Especially total factor productivities in food and beverage, textiles, paper, paper products and print ing are strongly affected by those of other industries. Total factor productivities of fabricated metal products, radio, television and communication equipment, motor vehicle and trailers, recycling have strong influence to those of other industries.

‘지리를 가르친다’는 것의 인문학적 의미

박승규(Seungkyu, Park) 대한지리학회 2019 대한지리학회지 Vol.54 No.1

이 연구는 지리를 가르친다는 것에 대한 인문학적 의미를 탐색한다. 지리를 가르친다는 것이 학교의 일상적 행위이기 때문이 아니다. 지리를 가르친다는 것에 대한 존재론적 고민 때문이다. 지리를 가르친다는 것은 지리학의 본질에 다가가는 것이다. 지리학의 본질은 땅에 새겨져 있는 흔적을 토대로 인간과 공간의 관계에 대해 살펴보는 것이다. 인간을 대상으로 하는 지리교육이기에 인간의 삶에 대한 관심은 지속하여왔다. 인간의 삶에 대한 이해 역시도 지리를 가르치는 과정에서 중요한 요소였다. 그런 점에서 지리를 가르친다는 것은 인문학적 의미를 담고 있다. 쓸모있고 실용적인 지리적 지식에 대한 교육을 넘어, 진학이나 취직과는 무관한 쓸모없는 무형의 가치를 지닌 지리적 지혜를 가르치는 것, 그것이 지리를 가르친다는 것에 대한 인문학적 의미인 것이다. 나아가, 지리를 가르친다는 것에 대한 존재론적 논의는 지리교육의 존재론적 논의로 연장되고 확장될 수 있다는 점에서 의미가 있다. This study explores the humanities meaning of teaching geography. Teaching geography is not because it is a routine activity of the school. It is because of ontological worries about teaching geography. Teaching geography is about reaching the essence of geography. The essence of geography is to look at the relationship between man and space on the basis of the traces carved on the ground. As it is a geography education for human beings, interest in human life has been continued. Understanding human life was also an important factor in teaching geography. In that respect, teaching geography has the humanities meaning. Beyond education on useful and practical geographical knowledge, teaching geographical wisdom with useless intangible values that are not related to further study or employment, it is the humanities meaning of teaching geography. Furthermore, the ontological discussion of teaching geography is meaningful in that it can be extended and extended to ontological discussion of geography education.

감성지리학의 지리교육적 의미 탐색 - 심미적 감성을 중심으로 -

박승규 ( Park Seungkyu ) 한국지리환경교육학회 2016 한국지리환경교육학회지 Vol.24 No.4

이 논문은 지리교육에서 심미적 감성의 의미에 대해 탐색한다. 심미적 감성은 이성과 감성의 상호보완적인 모습을 통해 인간 삶의 근원적 해석에 다가간다. 심미적 감성이 지리학과 지리교육에 기여할 수 있는 이유이다. 공간을 전유하고 있는 인간에 대한 이해는 분석적이고 과학적인 지리학으로는 접근하기 어려웠다. 심미적 감성은 이전에 경험하지 못했던 지리학의 미지의 영역을 열어준다. 지리교육에서 심미적 감성은 학교에서 가르쳐지는 지리학이 구체성의 과학임을 보여준다. 지리교육은 일상적인 삶을 명제적인 지식으로 바꿔 학생들에게 가르침으로써 삶의 생생함을 잃는다. 지리교육은 생기를 잃은 교육에서 벗어나, 현실적인 삶의 과정에서 느낄 수 있고, 인식할 수 있는 교육의 과정을 제공해야 한다. 심미적 감성은 듀이가 제시하는 흥미론의 이상을 지리교육을 통해 실현한다. 자아와 대상의 일체화를 지향하는 듀이의 흥미론은 인간과 공간의 관계를 통해 인간 존재를 인식하고자 하는 지리교육의 본래적 목적에 다가갈 수 있기 때문이다. The purpose of this study is to explore the meaning of aesthetic emotion in geography education. The aesthetic emotion is a unified entity which is not separated between reason and emotion. The aesthetic emotion tends to approach fundamental interpretation of life through mutual complement of reason and emotion. That is the reason that aesthetic emotion can contribute to geography and geography education trying to understand about “I” and “We” by considering the relationship between human and space. Perceiving aura from space as emotional awareness and understanding human being who possess the space exclusively from the perception is an area which is not interpretable by analytical and scientific approach. The aesthetic emotion can open the area of terra incognita of geography. The aesthetic emotion in geography education shows that geography teaching in school is an embodied science. Current geography education loses realistic vividness in terms of teaching students about our common life as transformed into propositional knowledge. Coming away from the geography education, it makes possible to create a course of geography education which feel and perceive the course of a vivid and realistic life. Also, it can accomplish the ideal of Dewey`s interest theory through geography education. Because, Dewey`s interest theory pursuing the coalition of ego and target can approach the goal of geography education which understand human`s existence by relationship between human and space.

고속 RISC 프로세서를 위한 가상 캐쉬 구조

박승규(Seungkyu Park),김동욱(Dongwook Kim),이준원(Joonwon Lee) 한국정보과학회 1996 정보과학회논문지 : 시스템 및 이론 Vol.23 No.9

본 논문에서는 캐쉬 액세스 시간이 direct-mapped 캐쉬와 같이 빠르면서, 캐쉬 성공율은 set-associative 캐쉬 처럼 높은, 고속 RISC 프로세서를 위한 새로운 가상 캐쉬 구조를 제안 한다. 이 구조에서는 전체 캐쉬 메모리를 n개의 뱅크로 나누고, 각 프로세스 생성시에 n개의 뱅크들 중에서 한개를 할당한다. 그러면, 각 프로세스는 자신에게 할당된 뱅크상에서 주로 수행되며, 그 뱅크상에서는 마치 direct-mapped 캐쉬처럼 동작 된다. 캐쉬 대치시에는 가장 늦게 스케쥴될 프로세스의 캐쉬라인을 희생 캐쉬로 선정하기 때문에 효과적인 대치가 이루어 진다. 트레이스 구동 모의실험 결과는 새로운 캐쉬 구조가 set-associative 캐쉬처럼 많은 충돌실패가 제거될뿐 아니라 캐쉬 액세스 시간이 direct-mapped 캐쉬 처럼 빠르다는 것을 보여 주고 있다. In this paper, we propose a new virtual cache architecture for fast RISC processors whose average access time is comparable to that of the direct-mapped cache while the hit ratio is the same as the set-associative cache. The entire cache memory is divided into n banks, and each process is assigned to a bank when it is created. Then, each process runs on the assigned bank, and the cache behaves like a direct-mapped cache. A victim for cache replacement is selected from those that belong to a process which is least likely to be scheduled in the near future. Results from trace-driven simulations confirm that the new scheme removes almost as many conflict misses as does the set-associative cache, while cache access time is similar to a direct-mapped cache.

박승규(Park, Seungkyu),이범현(Lee, Bum-hyun) 한국지역개발학회 2019 韓國地域開發學會誌 Vol.31 No.3

The purpose of this study is to empirically investigate the effects of population changes on regional economy due to changes in population, human capital with technology, and non-working(ageing) population by using regional statistical data of the National Statistical Office and the Bank of Korea from 2003 to 2016. As a result, the increased number of labor due to the increase of population decreased the production, consumption and capital steady-state of the metropolitan city and province, but the rate of convergence was rather increased. That is, growth of region was not achieved only by the growth of population. In addition, the increase of effective labor drove relatively decreasing tendency of capital and human capital along with consumption divergence in metropolitan city but province not. The growth of capital and golden rule of consumption due to increase of effective labor drove convergence in province. Finally, the increase of the non-working population, aging population, decreased capital, production and consumption of both metropolitan city and province, however, which resulted in an increase in technical progress. Therefore, with applying growth model to different regions, this study showed empirical results of the changes of population factors on change of regional economic factors.

COVID-19 역설과 지역경제 영향 간 실증분석

박승규(Park, Seungkyu) 한국지역개발학회 2021 韓國地域開發學會誌 Vol.33 No.1

This study empirically analyzed the impact of change of COVID-19 on the change of the PM10 from March 2019 to March 2020 by establishing a dynamic panel system model with considering the relations among the changes of industrial output, employment, and business economy in the capital(SMA) and non-capital(nSMA) regions. As a result, PM10 was decreased by the spread of COVID-19 of the SMA and nSMA due to the decrease of production in accommodation and food, culture and leisure industries. In particular, the production gap was affected by changes in voluntary and involuntary turnovers, and the industrial production gap increased relatively due to the gap in involuntary turnovers. In addition, as the business economy deteriorated, the gap in production change also increased. Thus, the spread of COVID-19 was not simply linked to a reduction of PM10, but decreased due to the changes through relating with the change of employment, production, and business economy. In addition, as a result of deriving the impact of COVID-19 by applying the trend from Nov. 1st to 31st, it increased the gap between voluntary and involuntary turnovers, which resulted in the increased gap of employment of manufacturing industries in the SMA and nSMA. On the other hand, the change of voluntary turnover in the manufacturing industry of the SMA increased, while the change in involuntary turnovers increased in the nSMA. In addition, productions of the manufacturing, and accommodation and food industries decreased due to the spread of COVID-19 in the SMA and nSMA, and the business economy in the service industry decreased compared to the manufacturing industry. Therefore, this study showed how PM10 of SMA and nSMA decreased due to the spread of COVID-19 by considering employment, production, and business economy.

요소생산성 차이에 의한 지역 부존자원의 비교 우위분석

박승규(Seungkyu Park),김의준(Euijune Kim) 한국경제통상학회 2011 경제연구 Vol.29 No.4

기존 연구에서는 비교우위의 부존자원을 상대적으로 수입하게 된다는 레온티에프역설이 지역에는 적용되지 않고 국가간에만 적용이 되는 특성을 제시하였다. 따라서, 본 연구는 지역에 레온티에프역설이 적용되는지의 유무를 파악하기 위하여, 2007년 지역산업연관표를 활용하여 기존 헥셔오린정리에서 가정한 동일한 생산기술과 지역 생산성을 완화한 헥셔오린바넥모형을 지역에 적용하였다. 생산성을 고려한 분석결과 16개 시·도 중 대부분의 시·도에서 레온티에프역설과는 달리 지역에서 상대적으로 풍부한 부존자원과 생산성을 활용하여 교역을 하는 것으로 분석되었다. 반면 생산성을 적용하지 않고 중간재를 적용한 경우에는 헥셔오린의 이론과 같이 레온티에프 역설이 지역에도 적용되는 것으로 나타났다. 따라서, 생산성은 규모의 성장으로 인한 발전 외에 지역의 비교우위 상품을 수출하는 원인으로써 부가적인 역할을 하는 것으로 분석되었다. Previous studies presented typical characteristics which Leonief paradox just applied to nations not regions. Therefore, this study applies Hechsher-Ohlin-Vanek model to 16 provinces in Korea with breaking down impractical assumptions along with regional different technology in order to confirm Leontief paradox may be applicable to regions. With applying different technology, most provinces tend to trade with their comparative abundant factor endowment unlike Leontief paradox. However, when intermediary goods is considered without concerning technology, provinces have trade patterns like what Leontief paradox presented. Therefore, this study proves that technology plays an extra role to export comparative abundant factor endowment beside promoting regional economy of scale.
