본 연구는 월동하는 끝동매미충의 충태별 분포를 두폭측정법을 활용하여 분석하였다. 끝동매미충 1령, 2령, 3령, 4령 및 5령 약충에 대한 두폭크기는 각각 0.381, 0.502, 0.673, 0.879 및 1.128mm였으며, 변이계수는 5.3, 4.0, 3.0, 4.5 및 5.3%였다. 성장률은 2령, 3령, 4령 약충에서는 1.31${\sim}$1.34로 큰 차이가 없었지만 5령에서 1.28로 약간 감소하였다. 두폭측정값의 회귀식을 구한 결과, LogY = 1.4627+0.1192X($r^2=0.9993$)으로 고도의 유의성이 인정되었고, Dyar 공식에 의한 적합도는 98% 이상으로 매우 적합하였으며, Dyar 계수(K)는 1.316이었다. 월동하는 끝동매미충의 밀도 및 충태 변화를 조사한 결과, 2006년 1월 하순에 0.25 $m^2$ 당 195마리가 채집되어 밀도가 가장 높았고, 월동 충태 조사에서는 90% 이상이 4령 약충이었다. 3월 중순부터 5령 약충의 발생량이 증가하였고, 월동 후 첫 성충발생은 4월 상순이었다. This study was conducted to investigate specific stages and distribution of overwintering nymphs of green rice leafhopper, Nephotettix cincticeps by measuring head capsule width. The nymphal head capsule width of the 1st instar to the 5th instar was 0.381, 0.502, 0.673, 0.979 and 1.128 mm, respectively. lts coefficient variation was 5.3, 4.0, 3.0, 4.5 and 5.3%, respectively. Growth ratio of each instar was not significantly different among 2nd to 4th instars as 1.31 to 1.34, but for the 5th instar it decreased as 1.28. The logarithm of the nymphal head capsule width was regressed as a function of the stage number of insects, resulting in LogY = 1.4627 + 0.1192X ($r^2= 0.9993$). Also fitness to the Dyar's law for the nymphal head capsule width of each instar was 98% or over and the Dyar's constant (K) was 1.316. The occurrence of N. cincticeps was maximum at the end of January with 195 individuals/0.25 $m^2$. The most abundant instar in the overwintering N. cincticeps population was 4th instar accounting for over 90%. Population of the 5th instar began to increase from mid-March, and adults began to occur in early April.

Whisker Growing Assisted 화학침착 공정으로 제조된 SiC_f/SiC 복합체의 파괴거동과 기계강도 평가

강석민,김원주,윤순길,박지연,Kang, Seok-Min,Kim, Weon-Ju,Yoon, Soon-Gil,Park, Ji-Yeon 한국세라믹학회 2009 한국세라믹학회지 Vol.46 No.5

$SiC_f$/SiC composites with whiskers and pyrolytic carbon (PyC) coated whiskers in the matrix were fabricated for enhancement of the fracture behaviors by the whisker growing assisted chemical vapor infiltration (WA-CVI) process, respectively. $SiC_f$/SiC composites were also prepared by the conventional CVI process as reference material. The mechanical properties and fracture behaviors were analyzed by comparison of the two types of composites prepared by WA-CVI and conventional CVI. The densities of $SiC_f$/SiC composites were in the range of $2.6{\sim}2.65g/cm^3$. The flexural strengths of composite with whiskers and with those coated by PyC were 650 MPa and 600 MPa, respectively. The tensile strength of composites with whiskers was ${\sim}285$ MPa.

품바전통의 문화적 재현과 상상적 아이덴티티

강석민(Kang, Seok-Min) 실천민속학회 2017 실천민속학연구 Vol.29 No.-

현재의 문화상황은 자본주의의 확장으로 인한 획일적인 공간의 확장 과정 속에서 지역적인 것들이 포섭되는 흐름에 놓여있다고 할 수 있는데, 그럼에도 지역의 발전 정도나 인종, 생태 등에 따라 각기 다양성과 역사성이 존재하기에 굴곡은 생길 수밖에 없다. 더욱이 현재의 민속은 문화산업의 흐름 속에서 거기에 집단의 전통 · 역사 · 형태 · 사상 · 관념을 충족시키는 방향으로 전개되고 있는 것일 수 있다. 품바전통은 이러한 흐름을 맞이하여 여러 방식의 매듭을 지어온 역사를 가지고 있다. 한국의 근대적인 자장 속에서 품바전통은 걸립 때 불렸던 타령이 전통으로 확립되기도 했고, 저항 국면에서 민중의 저항성을 담보한 것으로 이념적으로 활용되기도 했으며, 축제라는 형태로 문화시장에서 상품화되기도 했다. 또한 과거 전문연희집단과 유사한 형태라고 할 수 있는 장터의 품바 공연단이 활발하게 활동하고 있는 등 실로 매우 다양한 계열을 가지고 있다. 이렇듯 품바전통은 유산적 가치가 비교적 인정되지 못해 주변을 배회하면서, 오히려 더 다양한 매듭을 지어온 문화적 자원이었고, 그렇기에 전통/민속문화의 현대화 혹은 자원화 문제에 질문을 던질 수 있는 유용한 대상이 된다. 이 글이 대상으로 삼고 있는 음성품바축제는 지역 단위의 축제가 곳곳에서 의도적으로 창출되던 2000년에 시작하여 현재 17회에 이르고 있다. 음성품바축제는 지역의 예술단체인 음성문화예술협회와 음성군청, 음성 꽃동네라는 세 주체의 주도에 의해 창출된 것으로, 지역에 전해오던 ‘거지성자 최귀동’의 일대기를 축제의 근간으로 삼아 이른바 ‘정신문화축제’임을 꾸준히 표방하고 있다. 이 글은 이러한 점에 주목하여 음성품바축제를 로컬한 전통과 글로벌 문화가 만나면서 나름의 자리를 잡은, 즉 글로벌 문화의 국지성을 담보한 것으로 보고, 그것이 창출하는 상상적 경관들을 검토한다. 이 작업은 궁극적으로 문화자원의 유동적 흐름이라는 문화 경제적인 차원에서 현재의 민속을 검토하는 일이 될 것인데, 특히 이러한 과정은 품바전통이 가지고 있는 상징적인 이윤과 가치가 축적되고 확장된다는 의미에서 품바전통의 문화적 재생산 과정이라고 볼 수 있다. 또한 그 과정으로부터 품바전통은 다른 문화와의 차이이자 아이덴티티를 나름대로 구축하고 갖게 된다. It is a current cultural phenomenon that local cultures are embraced in the process of duplicating identical spaces due to the expansion of capitalism. This leads to a wide range of cultural and historical differences in various environments that have diverse races, ecology and different levels of development. Furthermore, cultural industry is likely to adopt the local groups’ cultural tradition and history, characteristics, and ideas and concepts in order to meet their cultural needs. Based on such circumstances, Pumba tradition has developed a variety of historical aspects. For example, Pumba tradition created a momentum that established Taryeong in the modern Korean society. Secondly, this tradition was ideologically used to express the people’s resistance when they were persecuted. Lastly, it was commercialized in the form of a festival in so-called culture markets, and there are many different Pumba theater companies that still give performances at local markets. These types of performance teams existed in the past and were called professional theater troupes. Such a tradition has developed with more diverse characteristics although it is not generally included in mainstream culture. These cultural resources would be valuable in terms of the cultural modernization of traditional and/or folk culture and the utilization of it. This research is primarily based on the Eumseong Pumba Festival, which has been held annually 17 times since 2000 when local festivals started to spring up. The festival was designed by three organizations: Eumseong Culture and Arts Association, Eumseong County Office, and Eumseong Kkot-dongnhe. They claim to support the cultural spirit of the festival by telling the story of a beggar whose name was Choi Guidong, an acclaimed saint by his local people. Eumseong Pumba festival features not only local tradition but also global culture, showing the locality of global culture. This study examined imaginative scenes shown at the festival with these characteristics. Through the Pumba festival, these scenes could be eventually be as part of current folklore in terms of the flow of flexible cultural resources. This could lead to symbolic profits and value being accumulated and becoming part of modern culture. This could also be considered a process of cultural reproduction of the Pumba tradition, and such a tradition can be distinguished from other cultures along with its own identity.

기술협력 네트워크에서의 사회적자본, 지식활용, 제품혁신성과의 관계에 대한 실증연구

Due to the awareness for the importance of social capital, many researches have investigated that social capital contributes to the successful implementation of product innovation. Although most researchers tried to model the effect of social capital on product innovation as a linear relation, we consider it too simplistic and fuzzy because knowledge utilization which ultimately leads to product innovation should exist in the relationship between social capital and product innovation. Using 107 survey data, this study found there is a partial mediating effect of knowledge utilization on the link between structure aspect of social capital and product innovation (i.e., new product development and improvement in existing products). Next, this study reported knowledge utilization does act as a perfect mediating variable on the link between awareness aspect of social capital and improvement of existing products, but act as a partial mediating variable on the link between awareness aspect of social capital and new product development. Finally, this study found that knowledge utilization does not act as a mediating variable on the link between relation aspect of social capita and product innovation.

The safety and efficacy of cardiac rehabilitation or exercise training in patients with heart failure (HF) have been investigated during the decades. Because exercise intolerance and easy fatigue are important symptoms in these patients, the potential role of cardiac rehabilitation program including regular exercise has been emerged. In the current guideline for patients with HF due to reduced systolic function, regular exercise program is Class I or IIa recommendation. Recently, a randomized prospective trial (Heart Failure-A Controlled Trial Investigating Outcome of Exercise Training, HF-ACTION) demonstrated that aerobic exercise modestly reduces the risk for clinical events in HF patients. However, cardiac rehabilitation program should be individualized and more research for heart failure with preserved ejection fraction (HFPEF) needed because approximately on half of patients with HF have preserved ejection fraction. There, this article provides the effects of regular exercise on clinical outcomes of HF patients and a brief practical guide for prescribing exercise in these patients.

한반도 도서의 거미상에 관한 연구

강석민(Seok-min Kang),김주필(Joo-pil Kim) 한국거미연구소 2011 한국거미 Vol.27 No.2

본 연구는 기존에 발표된 한반도 도서의 거미상 자료와 직접 채집한 거미상을 바탕으로 우리나라 18개 도서 지역에 분포하고 있는 거미상을 정리하여 거미분포도를 작성하고 MacArthur & Wilson 법칙을 적용하여 분석해 보았다. 조사된 섬의 거미상은 총 41과 166속 383종으로 나타났으며 모든 섬에서 우점하게 관찰된 과로는 왕거미과(Araneidae, 14.62%), 꼬마거미과(Theridiidae, 13.32%), 깡충거미과(Salticidae, 12.53%), 게거미과(Thomisidae, 6.53%), 갈거미과(Tetragnathidae, 5.48%)등으로 나타났고 모든 섬에서는 산왕거미(Araneus ventricosus), 말꼬마거미(Achaearanea tepidariorum)가 관찰되었다. 가장 많은 종이 관찰된 섬은 울릉도로 총 199종이 관찰되었고 가장 적은 종이 관찰된 섬은 욕지도로 30종이 관찰되었다. 울릉도에서는 다른 섬에서는 관찰되지 않은 거미 45종이 관찰되었고, 비금도ㆍ도초도, 욕지도는 다른 섬에서 관찰되지 않은 종은 없었다. 그리고 모든의 섬에서 한국 고유종들이 관찰되었으며, 남해안, 동해안에 위치한 섬들에서는 한국 뿐만 아니라 일본에서도 발견되는 종들이 관찰되었고 서해안에 위치한 섬들에서는 중국에서 발견되는 종들이 관찰되었다. 이는 우리나라의 지정학적 위치 특성에 따른 것으로 보인다. 본 연구는 다음 두 가지 결과를 통해 한반도 도서의 거미상 연구에 대한 의의를 가질 수 있다. 첫째, 한국 도서지역의 거미 분포도를 작성하였다. 둘째, 본 연구를 통해 나타난 결과를 기초로 생물지리학, 동물지리학 등의 응용분야에 대한 연구 가능성을 제시하였다. This research collected the information on the spider fauna living in 18 island regions of Korea from existing literature regarding the spider fauna in the islands of Korean. A distribution map was created and the spider distribution was analyzed applying MacArthur & Wilson theory. There arc 41 families, 166 genera, 383 species of spider fauna in these islands. In all islands, the dominant families arc Araneidae, Salticidae, Theridiidae, Tetragnathidae and Thomisidae. Every island has Araneus ventricosus and Achaearanea tepidariorum. Ulleungdo has the most diverse spider species with 199 species, while Yokjido has the least number of spider species with 30 species. Ulleungdo has 45 spider species, which cannot be found in other islands. Spider species found in BigeumdoㆍDochodo and Yokjido could be found in some other islands. In all islands, Korean endemic species were observed. In the islands located in south coast and east coast, spider species living in Korea and Japan were found. In the islands located in west coast, spider species living in Korea and China were found. It is believed that these are caused by the geopolitical location characteristic of Korea. This research has significance on spider fauna researches in the islands of Korean Peninsula with following two results. First, a spider distribution map of islands in Korean Peninsula was created for the first time. Second, application possibility of this research to other researches in the field of biogeography and zoogeography is suggested based on the result obtained.

This research collected the information on the spider fauna living in 18 island regions of Korea from existing literature regarding the spider fauna in the islands of Korean. A distribution map was created and the spider distribution was analysis applying MacArthur & Wilson theory. There are 41 families, 166 genera, 383 species of spider fauna in these islands.

In the islands located in west coast, spider species living in Korea and China were found. It is believed that these are caused by the geopolitical location characteristic of Korea. The interrelation among the number of spider species, size of islands, distances from main land and latitudes were analyzed. The result was that the habitats variety dependent on island size have impact on the number of spider species. Distance from main land and latitude do not have impact on the number of spider species. This research has significance on spider fauna researches in the islands of Korean Peninsula with following five results. First, a spider distribution map of islands in Korean Peninsula was created for the first time. Second, floristic locations and botanical names are updated to the most recent information. Third, application possibility of this research to other researches in the field of biogeography and zoogeography is suggested based on the result obtained. Fourth, spider distribution dependent on evolution was studied. It was found that spiders with developed visual instrument adapt to environment better and they have high occupation ratio. It suggests that more concrete research is required on the relation between evolution and capability of environment adaptation. Fifth, it was found by applying MacArthur & Wilson theory to Korean islands that the habitats variety indicated by island sizes give impact on the number of spider species. It was found that the distances from main land and latitudes do not have impact on the number of spider species.

민속연구의 긴장과 전환-담론장의 구조와 특이점의 분포-

강석민(Kang, Seok-min) 안동대학교 민속학연구소 2021 공동체문화와 민속 연구 Vol.1 No.-

이 글은 최근 제안된 공동체문화 연구 의제와 관련하여, 연구방법론의 종합적 도출을 위해 민속연구 담론의 지형을 검토한 것이다. 민속연구 담론의 기본 구조는 체제의 변환 즉 지구 자본주의 체제가 구성되는 역사적 과정 속에서 형성되었으며, 민속학의 제국적 식민적 형성을 ‘민속의 종획’이라는 관점에서 포착해볼 수 있다. 이에 그 궤적을 세 가지 특이점의 형성과 분포로 정리하여 현재 민속연구 담론의 장적 구조를 분석하고자 하였다. 첫째는 정체성과 지속, 동일성의 계열이고, 둘째는 원형과 변질, 두 ‘-이즘’의 창출이며, 셋째는 변환과 생성, 혼종성의 인식으로 그 특이점의 분포를 정리하면서, 담론장에서 발현되고 있는 민속연구의 특이성을 ‘전환’으로 살펴보고자 하였다. 현재의 시점에서 민속연구는 재현과 혼종성, 문화정치와 관련된 이론적 틀과 관련하여 확장된 논의의 진척 필요성이 제기되고 있으며, 공동체문화라는 연구 의제는 그러한 패러다임 전환과 관련된다고 하겠다. This study examined the topography of folk research discourse for the proposal of community culture research and the comprehensive derivation of research methodologies. The basic structure of the folk research discourse landscape is associated with the transformation of the system. In other words, folk research was formed in the historical process of forming a global capitalist system, which can be captured from the perspective of ‘enclosure of folklore’. This history is organized into the formation and distribution of three singularities, and the structure of the loadings of current folk research discourse is analyzed. The first is 〈the persistence and equality, affiliation of identity〉 and the second is 〈the circularity and degeneration, creation of two ‘-ism’s〉, and the third is 〈the generation and hybridity, recognition of transformation〉 to summarize the distribution of singularities. In addition, the peculiarity of folk research that is being expressed in the discourse is considered as a ‘transition’. At the present time, folk research has raised the need for progress in expanded discussions in relation to the theoretical framework related to representation, hybridity, and cultural politics. The research agenda of community culture is related to such paradigm transition.

This study is to examine the effect of technology cooperation as new paradigm for small and medium sized firms on product innovation. The degree and variety of technology cooperation are used to measure technology cooperation, and product innovation is used as a dependent variable in this study. Unlike the related studies, this study used small and medium sized firms located in Daegu and Kyungbook regions as a research sample, controlled for the degree of high -tech product, and included the roles of the knowledge management activities in the study. With 107 firms, the research results are reported as belows. First, technology cooperation of small and medium sized firms positively affects product innovation. Second, the positive effect of technology cooperation is reported in firms having the high-tech product, but in firms not having the high-tech product, the impact of technological cooperation is not significant. This study is worthy to provide the empirical evidence on the importance of technology cooperation to firms located in Daegu and Kyungbook regions. In particular, technology cooperation is important to small and medium sized firms that make high-tech product in the view of overcoming limited resources.
