In this paper, the existence of the organizational culture difference and the organizational effectiveness are studied. Many previous studies verified the relationship between the organizational culture categories and the organizational effectiveness. The Korean consumer electronics companies` measurement based on Rousseau`s organization culture style is surveyed, and is analyzed in order to obtain the differences of the employee`s attitudes. Rousseau`s culture style is composed of three components : constructive style, passive/defensive style, and aggressive/defensive style. The characteristics of each organizational features are examined using the statistical package. As a result, the organizational culture differences are found out. The elements of the constructive style represent positive values on attitude variables which are selected as the organizational effective variables. The elements of the passive/defensive style represent negative values of the attitude variables. Thus, they have an inverse relationship with this culture style. From the survey, the organizational effectiveness and the constructive style has a positive relationship. For the improvement of the organizational effectiveness, the organizational culture has to develop the constructive style.

韓國 保守主義의 딜레마

강정인(Kang Jung-In),이지윤(Lee Ji Yun) 신아시아연구소(구 신아세아질서연구회) 2003 신아세아 Vol.10 No.3

Since the December 2002 presidential election in Korea and continuing to date the conservative forces have held a series of demonstrations, called for a head-on struggle against the rival progressive forces, and harnessed the cyberspace to propagate their ideas. They all constitute unprecedented events that are aimed at articulating their own identity. On the other hand, the two recent discourses - "reformational conservatism"(with a focus on the reaffirmation of anticommunism) and "liberalist conservatism" - appear to reinforce its theoretical and practical retrogression and its existing immorality rather than acknowledging its past mistakes and renewing itself with forming the modus vivendi with the progressive forces. In brief, they all are symptoms of a long-held truism which scholars on conservatism in Korean politics have pointed out: "In Korean politics there are conservative forces, but no conservative ideology." This essay intends to offer the future direction of Korean conservatism by delving into the root causes of its ideological poverty. The genealogical sources of Korean conservatism's ideological poverty are multi-fold but can be grouped into the following three. First of all, since the Korean liberation in 1945 and the subsequent division of the Korean peninsula the political sphere (i.e., both the ruling and opposition parties) has been monopolized by the conservative forces. Even after the so-called "democratization" of Korean politics the conservative political structure has lingered on, thereby laying no grounds for competition and balancing between the conservative and progressive forces from which conservative philosophy would have emerged. Second, Korea's modernization process, which was essentially nonvoluntary and exogenous, has generated a set of fundamental contradictions between political conservatism and philosophical conservatism. Third, due largely to the dependence on foreign sources in the process of its formation and development, even the traditional thoughts and ideas have played little role in the formation of conservative philosophy. Taken together, it seems that there are two alternative paths from which philosophical conservatism in Korea could emerge. One path is to reinforce its existing connections with "sound" liberal democracy and the free-market economy. The other is to utilize the untapped sources of traditional thoughts.

안호상의 민족주의에 대한 비판적 성찰

강정인(Jung-In Kang),하상복(Sangbok HA) 인제대학교 인간환경미래연구원 2013 인간 · 환경 · 미래 Vol.- No.10

이 연구는 안호상의 민족주의를 자유주의적 가치와 다원주의적 가치의 관점에서 비판적으로 성찰하고자 한다. ‘한백성주의’로 명명되는 안호상의 민족주의는 혈연과 종교성에 기반을 둔 문화민족주의의 극단적 형태로 이해할 수 있으며, 민족과 국가의 이름으로 구성원들의 희생을 정당화하는 차원에서 반 자유주의적이며, 통합과 단일성의 가치 위에서 차이와 다양성을 부정한다는 면에서 반 다원주의적이다. 그와 같은 논리는 ‘다양성’과 ‘공존’의 원리 위에서 시도되는 한국 민주주의 다원적 기획과 양립하기 어려워 보인다. The purpose of this paper is to reflect critically An Ho Sang"s nationalism in the perspective of liberalism and pluralism. An"s nationalism, called "Hanbaekseong juui" can be defined as the extreme example of cultural nationalism based on the blood ties and the religious principle. This nationalism is anti-liberal by legitimating the individual sacrifice in the name of nation and state, and anti-plural by refusing the difference and diversity in the name of integration and oneness. This ideological orientation seems incompatible with the pluralist democratic project, that should be based on the political ideas of "diversity" and "coexistence".

비용효율적인 고고도 과학기구 개발 및 비행시험

강정표(Jungpyo Kang),심규진(Gyujin Shim),김휘호(Hweeho Kim),이용선(Yongseon Lee),이관중(Kwanjung Yee) 한국항공우주학회 2018 韓國航空宇宙學會誌 Vol.46 No.4

고고도 과학기구는 다양한 과학연구목표를 수행하기 위해 미국, 프랑스, 일본과 같은 항공우주선진국에서 수십 년간 사용되어 왔다. 고고도 과학기구는 초기 개발 및 운용비용이 막대하게 소요되므로 국가연구기관 중심으로 연구개발이 진행되어 왔지만 최근에는 저비용 고성능 오픈소스 소프트/하드웨어 생태계의 출현으로 과학기구 개발 진입장벽이 낮아졌다. 본 연구에서는 상용 기성품을 활용하여 저비용, 사용 용이성, 호환성, 제품 개발신속성을 고려한 소형 영압력기구(Zero Pressure Balloon) 시제품을 제작하였다. 또한, 8회에 걸친 비행시험을 통하여 비행운용기술을 축적하였으며 기구시스템의 작동신뢰성을 검증하여 향후 대형 영압력기구 운용을 위한 기반을 구축하였다. The high altitude scientific balloon has been used for decades in advanced aerospace countries such as United States, France, and Japan to carry out various research objectives. Since the initial cost for development and operation is enormous, it has been conducted by national research institutes. Recently, the advent of open source software/hardware ecosystems with low-cost yet high-performance have lowered barriers to enter into scientific balloon research and development. In this study, a zero pressure balloon prototype was designed considering the cost, usability, compatibility, and development period by using commercial off the shelf (COTS) items. In addition, the flight operation experience was accumulated through eight times of the flight tests, and operational reliability of the balloon system was verified. Finally, the foundation for the operation of the large zero pressure balloon was established.

강정애(Kang JungAi),최세경(Choi SeKyung),윤동열(Yoon DongYeol) 한국인사관리학회 2016 조직과 인사관리연구 Vol.40 No.1

본 연구의 목적은 2014년 실시된 한국장학재단의 차세대리더육성멘토링에 참여한 대학생들의 역량개선을 확인하는 것이다. 본 연구를 위하여 멘토링 효과에 대해 정성적 분석과 정량적 분석을 모두 실시하였다. 정량적 분석에서 독립변수는 멘티 개인의 참여율, 매개변수는 멘티 개인의 만족도, 종속변수는 개인행동역량, 사회교류역량, 지적활용역량 등의 역량개선도를 사용하였다. 역량개선도는 멘티가 자신의 역량수준에 대해 멘토링 시작과 종료 시 두 번에 걸쳐 자기보고식으로 평가하도록 하여 그 차이로 측정하였다. 또한, 멘티참여율과 멘토링 만족도의 관계를 조절하는 조절변수로 그룹참여율을 추가하여 분석하였다. 2014년 차세대리더육성멘토링을 수료한 1,876명으로부터 데이터를 수집하여 분석한 결과, 멘티참여율은 멘토링 만족도에 정(+)의 영향을 미치고, 멘토링 만족도는 세 개의 역량군 개선에 정(+)의 영향을 미치며, 멘티참여율과 역량 개선은 멘토링 만족도에 의해 매개되는 것을 확인하였다. 또한, 멘티참여율이 멘토링 만족도에 미치는 영향은 그룹참여율이 높을수록 강화되었다. This study examined the effects of Korea Student Aid Foundation(KOSAF)’s next-generation leaders mentoring(KORMENT) on university students’ competencies development. Data were obtained from a self-reporting essay of selected informants for a qualitative research, and from a questionnaire survey of participants in year 2014 for a quantitative study. Students’ competencies were measured before and after the mentoring program, the gap between two measurements refers to the degree of competencies development. The results of the study were as follows; First, a mentee’s individual participation rates have positive effect on mentoring satisfaction. Second, a mentee’s individual participation rates were more strongly related to mentoring satisfaction when the mentee group’s participation rates were high. Third, mentoring satisfaction has positive effect on a mentee’s competencies development. Finally, the relationship between a mentee’s participation rates and competencies development was mediated by mentoring satisfaction.
