BSCT 320${\times}$240 IRFPA detector module is implemented, which is a key component in uncooled thermal imaging systems. The detector module consists of two parts, infrared sensitive pixel array and read-out integrated circuit(ROIC). The BSCT 320${\times}$240 pixels are made by laser scribe process and 10-${\mu}m$ micro-bump to satisfy 50-${\mu}m$ pitch and 95-% fill-factor. The ROIC has been designed to electrically address the pixels sequentailly and to improve signal-to-noise ratio with single transistor amplifier, HPF, tunable LPF and clamp circuit. The fabricated hybrid chip of detector and ROIC has been mounted on the TEC built-in ceramic package for more stable operation and tested for lots of electrical and optical properties. The IRFA sample has shown successful properties and met with good results of fill-factor, detectivity and responsivity. 적외선 열 영상 system에서 가장 핵심이 되는 BSCT 320X240 IRFPA를 구현하였다. 검출기 module은 두 개의 부분, 즉 적외선 감지 pixel의 array와 감지된 신호를 읽어내는 ROIC로 구성된다. 50-${\mu}m$의 pitch와 95-%의 fill-factor를 만족하도록, laser scriber공정과 10-${\mu}m$ 크기의 ball을 갖는 micro bump공정을 적용하였다. ROIC는 선택된 신호를 읽어서 순차적으로 출력하게 설계되었으며, 단일 transistor amplifier, HPF, tunable LPF 그리고 clamp circuit를 삽입하여 SNR이 개선되도록 설계하였다. Detector와 ROIC의 결합으로 제작된 hybrid chip은 좀더 안정한 동작을 하도록 TEC가 내장된 ceramic package에 탑재하였다. 제작된 IRFPA sample은 원하는 특성을 만족하였으며, 특히 fill-factor, 탐지도, 반응도면에서 설계의 목표에 잘 근사함을 알 수 있었다.

Workplace bullying has received increased prominence in the last few years. Evidence clearly suggests that being the target of bullying is stressful, left unmanaged it can severely affect both targets and organizations. However, a significant area the remains to be explicitly explored is the potential detrimental impact of workplace bullying on knowledge sharing and organizational retaliatory behavior(ORB), which are critical to organization functioning. Therefore, one purpose of our study is to examine what is the influence of workplace bullying on employees` knowledge sharing and retaliatory behaviors. Knowledge sharing is important for any organizations today to make them into a competitive advantage because it provides a link between the individual and the organization by moving knowledge that resides with the individual to the organization level (Hendriks, 1999). As recent organizational learning theories have become a central focus in this field, successful knowledge transfers are increasingly seen as requiring an ongoing process of learning interactions (Szulanski, 2000). Retaliatory behavior refers to something antisocial and akin to unethical behaviors (Barclay et al., 2005). Since organizational retaliatory behavior places a stronger emphasis on the situational context in which the behavior occurs as the main catalyst, it may play an important role in illuminating the detrimental effect of bullying in the perspective of organizational administration. Next, consequences of workplace bullying, largely organizational costs, have been studied mostly with respect to its main effects. Accordingly, our second purpose in this research is to detect its interactive effects with such moderator variables: employability and employment status, instead of only simple associations between bullying and its conventional outcomes. Despite the fact that research on workplace bullying has focused almost exclusively on victims`perceptions, little is known about the role of target characteristics (Hoel, Rayner, & cooper,1999). As a person`s ability and readiness to identify and realize career opportunities, perceived employability and employment status―the type of employment, i.e. a temporary or a permanent employee―are critical to predict realistic responses to bullying given that both have an important influence on a worker`s attitude or awareness toward an event (e.g. Clarke, 2008; Virtanen etal, 2003). By studying their joint moderating effect on the stressor-strain relationships, research knowledge about workplace bullying as well as both moderators could be advanced. Valid and reliable self-report evaluation measures were administered to a sample of 311 workers in big three discount stores in South Korea. Discount store jobs present an exemplary case to study our research questions because there has been M&A and contingent employmentare largest in that industry, which are vulnerable to bullying. According to the results, exposure to bullying behaviors was negatively related to knowledge sharing and positively related to ORB, providing support for the respective hypotheses. Furthermore, employability moderated the relationship only for knowledge sharing, whereas employment status had moderating role only for ORB. That is, the negative relationship between bullying experience and knowledge sharing was stronger for those respondents rating their employability to be high. For contingent workers who are generally the last hired and first fired, the positive relationship between their bullying experience and ORB was weaker than permanent ones. The value of this study lies in increasing understanding of workplace bullying phenomena, as well as suggesting a potential prescription to maintain a bullying-free workplace.

This paper developed measurement indices for intellectual capital of public R&D organizations and investigated causal relationships among the components. We developed 10 measurement factors and 37 indicators and confirmed the reliability of these measurements. We offered an alternative to the existing model for searching causal relationships. From our survey research, using the structural equation model, we found a new relationship. In contrast to the existing model, we found a cycling relationship among three variables: human capital causes structural capital, structural capital causes relational capital, and relational capital causes human capital.

본 연구는 윤리적 행동-커리어 성공의 연계성과 조직정치 지각간의 관계와 이들의 커리어 몰입과 훈련에 참여하려는 동기에 대한 영향을 검토하고자 하였다. 개념들간의 관계는 기존 문헌들에 근거하여 가설화되었으며, 수도권에 위치한 15개 대기업에 근무하는 477명의 사무직 종사자들로부터 설문을 통해 검증되었다. 구조방정식모델(structural equation modelling: SEM)은 윤리적 행동-커리어 성공의 연계성이 조직정치 지각에 대한 강력한 예측변수가 될 뿐만 아니라 이들 두 변수들은 구성원들의 차후 커리어 몰입과 훈련에 참여하려는 동기에 대해서도 직접 또는 간접적인 효과가 있음을 입증했다. 즉, 윤리적 행동-커리어 성공의 연계성은 커리어 몰입에 대한 직접적인 영향력이 없었지만 지각된 조직정치를 통해 커리어 몰입과 훈련에 참여하려는 동기에 각각 부(-)의 영향을 미쳤다. 조직정치의 지각은 커리어 몰입 및 훈련에 참여하려는 동기에 대한 직접효과 외에도 훈련 참여 동기에 대해서는 커리어 몰입을 통한 간접효과를 나타냈다. 이러한 결과를 바탕으로 실무적 시사점과 향후 연구에 대한 논의가 이루어졌다. This study investigates whether ethical behavior-career success association is a significant correlate of organizational politics perception and how the two perceptional variables affect career commitment and motivation to participate in training. Relationships among the constructs are predicted based on relevant literature, and are tested using survey result form 477 employees working in fifteen of the leading corporations in South Korea. Structural equation modeling (SEM) shows that the association between ethical behavior and career success is a significant predictor in perception of organizational politics. As a mediator, each perception also affects employees' career commitment and their motivation to participate in training. The implications for theory and practice are discussed.

파견 관리자의 정치적 스킬과 문화지능의 효과:중국진출 한국기업들에서의 입증

강대석(Dae-seok Kang),제단화(Danhua Qi),김재철(Jae-Cheol Kim) 한국인사조직학회 2017 인사조직연구 Vol.25 No.1

관리자 파견에 관한 이슈는 시장 글로벌화에 따라 분명 중요한 사안임에도 불구하고 그동안 HR 연구의 흐름에서 주류가 되지는 못했다. 파견 관리자들의 성공요인들을 검토한 기존 연구들은 주로 글로벌 리더로서 관계적 역량만을 강조해 왔다. 직접적으로 정치적스킬의 중요성을 다루었던 소수의 연구들이 있었어도 실증연구는 거의 이루어지지 않았다. 이와 관련하여 본 연구는 파견 관리자 리더십 역량의 관점에서 이들의 정치적 스킬과 문화지능이 현지 직원들의 태도 및 행동에 미치는 영향을 검토하고자 했다. 구체적으로, 부서 내 과업/관계갈등, 그리고 침묵 및 제언에 대한 현지 직원들이 지각하는 파견 관리자정치적 스킬의 영향력을 분석했으며, 아울러 문화지능과의 상호작용 효과에 대해서도 살펴보았다. 기존 연구들을 바탕으로 개념들 간의 이론적인 관계가 가설화되었으며, 중국에 진출한 36개 한국기업에 근무하는 466명의 중국인 직원들로부터 획득한 설문데이터를 통해 가설이 검증되었다. 위계적 조절회귀분석을 이용한 분석 결과, 예상대로 파견 관리자의 정치적 스킬은 현지 직원들의 과업/관계갈등, 그리고 침묵에 대해 부(-)적인 영향을 미쳤으며, 제언에 대해서는 정(+)적인 영향을 나타냈다. 문화지능은 제언을 제외한 나머지 변수들에서 모두 정치적 스킬과 유의한 상호작용 효과를 나타냈다. 즉정치적 스킬과 과업/관계갈등 그리고 침묵의 부(-)적인 관계는 문화지능이 높은 경우에 더욱 강화되었다. 이 같은 결과들은 글로벌 리더십 연구의 발전과 사회지능에 관한 이론적 확장에 기여할 뿐만 아니라 실무적으로도 국내외를 막론해 관리자의 발탁과 교육콘텐츠개발에 일조할 것으로 기대된다. 관리자들이 정치적 스킬과 더불어 문화지능까지 가지게되면 기대 이상의 가산성으로 말미암아 보다 완벽에 가까운 효과적인 리더십 역량을 갖추는 것이 될 것이다. The issue of expatriate adjustment rarely received a mention in the mainstream HRM literature despite the fact that expatriate assignments are important for multinational corporations (MNCs). Much of the existing literature related to expatriate success has focused mainly on managers’ relational competence(e.g., Harvey & Novicevic, 2004). Nevertheless, there is little empirical research that dealt with the importance of their political skill in the perspective of communication choice and the emergence of conflicts among work group members. The purpose of this study is to explore the relationship between expatriate managers’ political skill and employees’ perceptions of task and relationship conflict, as well as communication behaviors such as voice and silence. We propose that political skill influences the dependent variables, along with the moderating role of managers’ cultural intelligence in the relationships. Valid and reliable self-report evaluation measures were administered to a sample of 466 host country employees working for 36 Korean companies in China. The findings using hierarchical moderated regression showed that leader political skill has a negative impact on task/relationship conflicts and silence, but a positive impact on voice. Findings also indicated that cultural intelligence shows incremental validities when political skill predicts task/relationship conflicts and silence. Based on these results, we present significant insights about leadership and social intelligence, and implications about manager selection and education contents development.
