성창수,김지석 한국체육교육학회 2019 한국체육교육학회지 Vol.23 No.4

본 연구의 목적은 중학생의 통학 방법이 인체조성 및 건강체력 요소의 변화에 미치는 효과를 분석하는 데 있다. 총 293명(남학생 155명, 여학생 138명)의 중학교 1학년 남·여 학생이 연구에 참여하였으며, 설문조사에 의해 파악된 학생들의 통학 방법에 따라 도보 통학 그룹(Wlk), 자전거 통학 그룹(Bik), 대중교통 이용 통학 그룹(Vhc)으로 구분되었다. BMI, 근육량, 체지방량, 복부지방 등 인체조성은 생체전기저항법에 의해 측정되었으며, 각각의 체력 요인은 악력(근력), 윗몸일으키기(근지구력), 사이드스텝(민첩성), 서전트 점프(순발력), 좌전굴(유연성), 외발서기(평형성) 등으로 측정하였다. 상완이두 및 대퇴사두 근파워는 MicroFet2를 이용하여 측정되었다. 측정 결과, 남학생의 골격근량, 팔근육량, 다리근육량, 기초대사랑, 악력, 유연성 등에서 자전거 통학그룹이 대중교통 이용 그룹보다 유의하게 높게 나타났으며, 여학생에서는 도보 통학 그룹의 복부비만율과 내장지방량이 대중교통 이용 그룹보다 유의하게 낮았다. 체육수업 시간, 방과 후 체육활동 시간, 식이, 평균 수면시간 등 전체적인 생활 패턴은 모든 그룹에서 통계적인 차이가 나타나지 않았다. 즉, 본 연구에서는 성장과 생활형태가 유사한 중학교 1학년 학생들에게서 자전거, 도보와 같은 활동성 통학이 대중교통 등을 이용하는 비활동성 통학에 비해 남학생에게서는 근육량의 증가를, 여학생에게서는 체지방 관련 요인을 감소시키는 효과가 있는 것으로 나타났다. Purpose: The purpose of this study was to analyze the effect of commuting methods on the body composition and physical fitness in middle school students. Methods: 293 first-year middle school students (male: 155, female: 138) were recruited and subjects were classified according to their commuting methods, such as walking(Wlk), bicycling(Bik) and vehicle-movement(Vhc). Body composition including BMI, muscle mass, fat mass, and abdominal fat, etc. was measured by 4-point bioelectrical impedence analaysis. Sit-up, sidestep, sargeant jump, grip strength, sitting torso flexion test, one-leg balance test were performed for measuring physical fitness. The strength of skeletal muscle was measured with MicroFet2 dynamometry. Results: Total skeletal muscle mass, arm muscle mass, leg muscle mass, basal metabolic rate, grip strength, and sitting torso flexion were significantly higher in Bik group compared to the Vhc in male students. Waist-hip ratio and visceral fat mass were significantly lower in Wlk group compared to the Vhc in female students. Overall life patterns, such as weekly hours of physical education class, exercise hours after school, diet, and average sleeping hours, etc. were not significantly different in between groups. Conclusion: The current study has shown that the active commuting itself can enhance the levels of physical fitness and body composition in the teenagers.

성창수,정기한 한국자료분석학회 2008 Journal of the Korean Data Analysis Society Vol.10 No.5

The purpose of this paper is to investigate the main determinants of Strategic Orientation and it's effect on business performance focused on domestic firms. Based on various previous literature review, market orientation, entrepreneurial orientation and relationship orientation are chosen as the determinants of strategic orientation. Hypotheses were tested through field study conducted for 232 empirical survey results from CEOs and managers. The hypothesis that all strategic orientations will affect positively on business performance also accepted. These results show that firms possessing high levels of market orientation, entrepreneurial orientation and relationship orientation exhibit superior business performance. The authors discussed the present findings and limitations as well as directions for future research were also discussed. 본 연구의 목적은 국내 기업을 대상으로 기업성과에 중요한 영향을 미치는 대표적 전략지향성의 3가지 구성 개념인 시장지향성, 기업가지향성, 관계지향성의 개념을 설명하고 이러한 전략지향성이 기업성과에 미치는 영향관계를 실증연구를 통해 분석하였다. 유효표본 232부가 실증분석에 활용되었으며 관리자급 이상의 CEO가 분석대상이었다. 연구모형의 분석은 SPSS 15.0을 이용하여 변수들에 대한 신뢰성과 타당성을 분석하였으며, 상관관계분석, 다중회귀분석을 통해 가설을 검증하였다. 실증분석결과 시장지향성, 기업가지향성, 관계지향성이 기업성과에 모두 유의한 영향을 미치는 것으로 나타났다. 기업의 의사결정과 전략실행에 있어 고객과 시장에 대한 이해와 대응, 경영자의 기업가적인 마인드와 이해관계자와의 관계지향성이 높을수록 기업의 성과가 높아지는 것을 알 수 있다. 따라서 기업은 변화하는 시장 환경과 고객의 요구에 대응하는 전략적인 노력이 필요할 것이다.

UN자료이용과 UN기탁도서관 운영에 관한 연구

성창수 한국도서관·정보학회 2001 한국도서관정보학회지 Vol.32 No.2

UN기탁도서관제도는 아직 우리에게 많이 생소하다. 국제연합(UN)은 다양한 문화, 민족, 정치, 경제적 환경을 가진 국가연합체로서 창설 초기부터 활동과 정책들을 문서화하고 있으며, 각 기구의 활동에서 생산된 각종 법률과 수천 종의 정기간행물과 단행본 등은 다양한 정보를 수록하고 있어서 문헌정보학 자료로서 중요한 의미를 가지고 있다. 이러한 자료는 UN회원국은 물론 전세계의 이용자층을 확보하고 있다. 또한 UN은 기탁 도서관제도를 통해서 이들의 요구에 부응하고 있으며 전세계 지정기탁도서관에 자료를 배포하고 있다. 우리 나라는 1990년대부터 다량의 UN자료가 국내 기탁도서관으로 입수되고 이다. 그러나 국내의 학계나 관련 단테는 UN자료에 대한 관심과 인지도가 부족한 것이 현실이다. 이 시점에서 본 연구는 이용자에게 UN자료에 대한 인지도를 높이고 이용을 촉진할 수 있는 방안을 제시하고자 한다. United Nations Depository Library Systems is not yet well known to the Public. United Nations as an international organization founded on the basis of various cultures, ethnic groups and political & economical backgrounds, have complied all its policies and activities into various type of materials in written form from the beginning. These materials including laws, periodicals and monographs produced from UN\`s various activities have a great vale as library materials containing useful information. UN has distributed them throughout the designated libraries called UN Depository Libraries for the world users. So UN materials are available to users not only from the member countries but from the world. I the Republic of Korea several depository libraries have received a large quantity of UN materials since the 1990\`s. However, these materials have not been utilized well. Under thee circumstances, this study tries to present the ways to promote user\`s understanding of UN material and encourage them to use the valuable information more effectivity.

16S rDNA 클론들의 RFLP 비교분석에서 얻어진 Pentachlorophenol의 혐기성 분해에 따른 미생물군집의 변화

성창수,권오섭,박영식 한국미생물학회 1997 미생물학회지 Vol.33 No.2

We have employed comparative RFL,P(Restriction Fragment Ixngth Pol~iniorphism) analysis and molecular phylogenetic techniques to investigate the diversity of uncultured microorganisms associated with the anaerobic PCP degradation in PCP-adapted enrichment cultures inoculated by samples from anaerobic cewage sludgc(Jangrim, Pusan) and leachate of landfill site(Kimhae). 16s rDNA cloncs were obtairted by PCR amplification of mixed population DNAs extracted directly from the nonactive and active stage ol each PCP-adapted culture. After three rounds of comparative RFLP analyses. two RFLP types. designated as Ala and Hld, were found prevalent and common in both active stage samples. Thc analysis of phylogenctic diversity bawd on the 5'-terminal 180 nt of sequences from whole clones of the Ala and Bld RFLP types showed close similarity among themselves. In case of Bld clones, 7XQ of them shared identical sequences. Thcse resuliq suggest that the clones of both RFLP types wcre originated from highly affiliated microorganisms which are e~iriched as a result of metabolic activity to PCP. The full-length 16s rRNA sequence of each representative clone from both RFLP types was determined. and an Ala clone w i n found to he related to Clo.strrdiurn ulfutzac~(Genk~ank No. Z69203) and a Bld clone to Thermobacteroides proteolyticus(Genbank No. X09335), with sequence similarities of 89%' and 97%. respectively. Pentachlorophenol(PCP)가 첨가된 혐기성 무기배지에 혐기성 소화조슬럿지와 쓰레기 매립장의 침출수를 각각 접종한 후, 활성을 보이기 전과 후의 각 시료 내에 존재하는 총유전물질로부터 16S rRNA 유전자를 PCR 증폭하여 이들에 대한 restriction fragment length polymorphism(RFLP) 비교분석과 계통수분석을 실시하였다. 3차에 걸친 RFLP 분석 결과 Ala와 Bld로 명명된 두 가지의 FRLP 유형이 두 가지의 활성시료 모두에서 높은 빈도로 발견되었다. 이들 유형에 속하는 모든 클론들의 5'쪽에 해당되는 180개씩의 염기서열분석을 실시하여 계통수 분석을 실시한 결과, 각각의 유형에 속하는 클론들간에는 높은 상동성을 가지는 것으로 확인되었다. 특히 Bld 유형에서는 78%에 해당되는 클론들이 동일한 염기서열을 가지는 것으로 확인되었다. 이들 Ala와 Bld 유형에 속하는 클론들은 PCP에 대한 분해활성의 결과로서 증식된 유사종의 미생물 군집에서 비롯된 것으로 추정된다. 이 두 가지 유형에 속하는 클론들 중 하나씩의 16S rDNA 전체으 염기서열을 분석한 결과 Ala의 클론은 Clostridium ultunae (Genbank No. Z69293)의 염기서열과 89%의 상동성을 보였으며, Bld의 클론은 Thermobacteroides proteolyticus (Genbank No. X69335)의 것과 97%의 상동성을 가지는 것으로 나타났다.

성창수,박주연 한국주거환경학회 2017 주거환경(한국주거환경학회논문집) Vol.15 No.4

In urban regeneration, it emphasizes the role of the city as a solution to urban problems such as traffic congestion and crime in order to create a safe and efficient urban residential environment. This includes efficient and safe urban management and public safety. In particular, it is important to raise awareness of crime prevention and safety by applying a surveillance system such as CCTV to reduce citizens' anxiety about crimes exposed to vulnerable subjects and rectangular areas and to improve safe residential environment. Therefore, this study investigates safe residential environment according to installation of local monitoring system analyzing the case study using big data in urban regeneration project. According to the results of the study, the priority area of the regional surveillance system is high vulnerable to crime, It also shows that the installation area of the local surveillance system due to the big data analysis is closely related to the installation requirements of unsafe and unstable residents, and is also consistent with the blind spot that is not easily recognized and disclosed. These results show that voluntary participation and cooperation of local residents are important for urban regeneration and safe residential environment. Based on this, local governments can apply accurate information in safe urban regeneration projects to cope with each citizen's requests and complaints appropriately.

일반 논문 : 시니어창업 의사결정에 미치는 영향요인에 관한 연구

성창수 ( Chang Soo Sung ),김진수 ( Jin Soo Kim ) 한국중소기업학회 2011 中小企業硏究 Vol.33 No.3

최근 우리나라는 ``고용없는 성장의 시대``에서 급속한 고령화와 조기퇴직의 사회현상은 청년실업과 더불어 사회경제적으로 큰 영향을 초래할 전망이다. 이와 더불어 약 712만 명의 베이비붐 세대가 주 퇴직연령대에 진입하면서 생산인력 부족현상의 초래 및 경제적 위협에 따라 정년을 맞은 시니어 세대의 구직난이 본격화되고 창업에 대한 참여 및 관심은 점차 높아지고 있다. 이러한 환경변화에 따라 시니어창업의 중요성을 재인식하고 급변하는 창업환경에서 창업을 준비하는 시니어 창업가의 특성을 규명하는 연구의 필요성이 높아지고 있다. 이에 본 연구에서는 급변하는 창업환경에서 시니어 창업가의 개인적 특성요인인 기업가정신과 창업역량 및 환경요인이 창업의도와 초기 창업가 행동에 미치는 영향요인을 규명하여 각 연구 개념간의 연관성을 밝히고자 한다. 이를 바탕으로 시니어창업의 의사결정에 영향을 미치는 개념들의 세부 메커니즘과 구체적인 적용방향을 제시함으로써 새로운 위기에 직면한 시니어의 성공창업을 위한 기초 자료를 제안하는 것을 목적으로 한다. 실증분석결과는 다음과 같다. 첫째, 기업가정신이 창업태도에 미치는 영향관계를 검증한 결과, 위험감수성은 창업태도에 영향을 미쳤으나 자율성과 진취성은 창업태도에 영향을 미치지 못하였다. 둘째, 창업역량은 창업태도, 주관적 규범, 인지된 행동통제에 유의한 영향을 미쳤다. 셋째, 창업태도와 인지된 행동통제는 창업의도에 각각 유의한 영향을 미쳤으나 주관적 규범은 창업의도에 직접적인 영향을 미치지 못했다. 넷째, 창업의도가 초기 창업가 행동에 미치는 영향관계를 검증한 결과 기회발견과 기회개발에 유의한 영향관계가 나타났다. 마지막으로 본 연구 결과에 대한 다양한 시사점과 연구의 한계점 및 향후 연구를 위한 제언을 제시하였다. The current socioeconomic condition in South Korea is characterized by early retirement and a shift toward an elderly society. The fact that the age group of 50 or older is about 46.7% of total workforce poses a threat for future economic growth crisis. (The fact that the age group of 50 or older composes 46.7% of the total workforce could be a detrimental factor for future economic growth.) Even now in South Korea`s contemporary society, the retired workforce suffers economically as well as socially. To solve these socioeconomic problems, Small Business Administration is running many different projects and public policies to support senior entrepreneurship. Recently, developed countries such as the U.S., England, Australia and New Zealand have recognized the importance of senior entrepreneurship and are performing various research to systemize concepts for senior entrepreneurship. TTo solve these socioeconomic problems, the Small Business Administration is running many different projects and public policies to support senior entrepreneurship. Recently, developed countries such as the United States, England, Australia and New Zealand have recognized the importance of senior entrepreneurship and are performing various research to systemize concepts for senior entrepreneurship. The purpose of this research was to explain the concept of senior entrepreneurship and the importance of it by systemizing the relationship between beginner entrepreneur and entrepreneurial intention. As the ultimate objective of this research is to develop a systematic strategy to enhance the current entrepreneurial decision making process for senior entrepreneurs, the focus of this research has been set to the details about factors and mechanisms that influences start ups by senior entrepreneurs. Importantly, to identify general process of senior entrepreneurship, Ajzen`s (1991) Theory of Planned Behavior model was used. After reviewing the relevant literature, we developed a model and set our research hypotheses as follows H1: Risk taking will have a positive effect on entrepreneurial attitude. H2: Autonomy will have a positive effect on entrepreneurial attitude. H3: Proactiveness will have a positive effect on entrepreneurial attitude. H4: Entrepreneurial skill will have a positive effect on entrepreneurial attitude. H5: Entrepreneurial skill will have a positive effect on subjective norms. H6: Entrepreneurial skill will have a positive effect on perceived behavioral control. H7: Entrepreneurial attitude will have a positive effect on entrepreneurial intention. H8: Subjective norms will have a positive effect on entrepreneurial intention. H9: Perceived behavioral control will have a positive effect on entrepreneurial intention. H10: Perceived barriers will have a negative effect on entrepreneurial intention. H11: Perceived support will have a positive effect on entrepreneurial intention. H12: Entrepreneurial intention will have a positive effect on the discovery of business chances. H13: Entrepreneurial intention will have a positive effect on the exploitation of business chances. To get the sample data, survey was conducted between October 25, 2010 and November 13, 2010 of seniors who graduated from a senior entrepreneurship academy operated by the Korea Small Business Administration. We received 371 responses and excluded 141 responses due to incomplete answers. Finally we accepted 230 samples. We employed two statistical packages, SPSS 15.0 for descriptive and reliability analysis and AMOS 7.0 for confirmatory factor analysis and structural model analysis with latent variables. We found that questionnaires containing incomplete answers had two types. The first type, which were about thirty six percent of the incomplete questionnaires, were missing more than fifty percent of the values per construct. To use incomplete questionnaires in statistical tests, we adopted a regression input for the missing values which were less than fifty percent of the items per construct. Second, we eliminated questionnaires containing a series of the same response value or of the same response values pattern. Although we tried to translate English questions into Korean questions to make it easy to check values, seniors who are about fifty years old or older may have difficulties to respond to these questions because of their age. The minimum value of Cronbach`s α in the twelve research constructs is 0.721 and the maximum is 0.906. Fit indexes of confirmatory factor analysis model are χ2(df)=491.116(368), p=0.000, RMSEA=0.038, GFI=0.888, AGFI=0.848, TLI=0.956 and CFI=0.965. In this test, composite reliabilities are 0.640 through 0.892 and AVEs (Average Variance Extracted) are 0.472 through 0.814. Research constructs in confirmatory factor analysis have discriminant validity because all of the 95 percent confidence intervals of correlation coefficient among the twelve latent variables do not include one. Fit indexes of our research model represent a satisfactory level in structural equation analysis (χ2(df)=643.475(406), p=0.000, RMSEA=0.051, GFI=0.854, AGFI=0.821, TLI=0.923, CFI=0.933). In the research model, significant paths/standardized coefficient/hypotheses are as follow; 「entrepreneurial skill → entrepreneurial attitude, 0.080」(H4), 「entrepreneurial skill → subjective norms, 0.703」(H5), 「entrepreneurial skill → perceived behavioral control, 0.894」(H6), 「entrepreneurial attitude → entrepreneurial intention, 0.296」(H7), 「perceived behavioral control → entrepreneurial intention, 0.395」(H9), 「entrepreneurial intention → discovery, 0.603」(H12), 「entrepreneurial intention → exploitation, 0.217」 (H13). We should revise our research model because, in testing the research model, there were two paths containing M.I. of more than ten. So, we tested the revised model with added two paths in the research model. The two paths were 「subjective norms → entrepreneurial attitude」 and 「subjective norms → perceived behavior control」. Fit indexes of the revised model were better than those of the research model (χ2(df)=619.654(404), p=0.000, RMSEA=0.048, GFI=0.857, AGFI=0.825, TLI=0.930, CFI=0.939) and the χ2 difference test between the revised model and the research model was significant. So we accepted the revised model as the final model. In the final model, we found full mediation effects of entrepreneurial attitude and perceived behavioral control, respectively in the relationship of subjective norms and entrepreneurial intention. The overall results supported H1(0.469), but not H2(-0.216, -0.172). The result shows that risk-taking, rather than autonomy, is the factor that influences entrepreneurial decision making for seniors(Dess and Lumpkin, 2005). Results also supported H4(0.458), H5(0.485), H6(H510). Similar to the Linan`s(2008) proven fact, entrepreneurial capabilities have been shown to have the largest impact along with entrepreneurial behavior, subjective norms, and perceived behavioral control. H7(0.383) and H9(0.386) were supported by the results, but H8 was rejected. The overall result is similar with previous research performed by Linan(2008) and Linan and Chen(2009). On the other hand, H10 and H11 were rejected due to the lack of government support for senior entrepreneurship and the lack of a suitable socioeconomical environment. Lastly, H12(0.597) and H13(0.214) was supported by the results. The results of this research were organized by Ajzen`s(1991) TPB model. According to the results, there were positive relationships between entrepreneurial behavior, entrepreneurial intention, and entrepreneurial capabilities. These results show that the Senior Entrepreneurship Education Center should focus on educating seniors based on enhancing entrepreneurship capabilities. In addition, since risk taking was the only factor that affected entrepreneurial behavior, it is important to educate seniors to manage possible risks. Another result showed that subjective norms had a relatively large impact on entrepreneurial behavior and on perceived behavioral control. Therefore, entrepreneurship education institutions should focus on building a curriculum based on communication. Lastly, Korean senior entrepreneurs were found to focus on opportunity findings rather than environmental restrictions. This shows that it is realistic for the government to support senior entrepreneurship rather than putting the focus on economic relief. Limitations and future research proposals have been categorized in seven different parts. Following is the list of those categories: lack of previous research about senior entrepreneurship, need for longitudinal study, limitation on error estimation, limitation on samples, need for various approach methods on senior entrepreneurship, need to develop a comparison model between senior and young adult entrepreneurs, and a need to categorize senior entrepreneurs based on the years they were in business.
