The purpose of this study is to analyze the diffusion period and productivity of smartwork in an organization. Firms are increasingly interested in smartwork for non contact work and working from home because of the corona 19. The smartwork is a new technology that changes face-to-face work in an organization. It helps the work of individuals and organizations regardless of time and place. The theoretical background describes the complexity, system thinking, diffusion theory, smart work, organizational resistance, and productivity. This study analyzes the diffusion period and productivity of smart work through business simulation techniques. A simulation study progresses four stages. There are problem definition, hypothesis establishment and causal loop diagram, model construction and verification, and policy evaluation. The simulation models contain an individual's resistance variables organizational investment and leadership variables related to the operation of smartwork. The organizational investment variables include organizational culture, legal system, implement systems and technology investment. The individual resistance variables include cognitive, attitude, structure and technological resistance. The leadership includes leadership interest variables and performance linkage variables. The simulation executed the changes of a people number adopting smart work and the organizational productivity monthly. As a result of the simulation, many organization members have accepted the smart work innovation after 20 months. The organizational productivity through smart work showed very high value after 16 months. In scenario analysis, the individuals' awareness and attitude resistance showed very important variables to productivity and a personal change of smart work adoption. Meanwhile, The organizational investment showed that the high driving-force increased not productivity and the low driving-force showed decreased low productivity. Also, leadership variables showed a powerful driver for changing smart work productivity. The implication of the study has suggested extending complexity, diffusion theory and organization resistance theory based on simulation methods.

본 연구에서는 구직기간과 근속기간에 미치는 비인지적 요인의 영향을 살펴보았다. 한국노동연구원의 노동패널 18차 삶의 인식에 대한 부가조사자료에는 개인의 비인지적 특성을 묻는 질문 문항이 들어있다. 노동패널자료를 사용하여 big5 성격특성과 통제소재 변인에 대한 내적일치도를 살펴보고, 분석방법으로는 구직기간과 근속기간 등 절단(censored)이 있는 표본을 포함하고 있는 자료의 분석에 적합한 비례위험해저드모형을 사용하였다. 추정결과 성격특성과 통재소재 등 비인지적 요인이 개인의 노동시장 성과에 영향을 미치는 것을 확인하였다. 구직기간 분석에서 성격요인 중 성실성이 성인구직자의 구직기간을 길게 하여 실업탈출률을 낮추는 것으로 나타났다. 이는 실업과 같은 불확실한 상황에서는 성실성으로 표현되는 신중함이 구직에 필요한 정보해석을 잘못하거나 왜곡할 수 있고, 결단성의 결여로 실업탈출에 제약이 되는 것으로 보인다. 근속기간 분석에서는 내적통재 소재자의 경우 근속기간이 길어 직장이탈가능성이 낮았다. 내적통재소재자는 내가 열심히 하면 조직에서 성공과 승진이 가능하다고 믿는 경향이 강하기 때문에 조직에 의해 더 선호될 수 있으며, 내적통제 경향이 강할수록 스스로의 행동에 대한 동기부여와 자제심이 크기 때문에 한 직장에 오래 머물 수 있는 요인이 되는 것으로 보인다.

Objectives : The purpose of this study was to investigate the deficits in executive function in children with ADHD and anxiety disorder, and further, to characterize executive function deficits among the two groups. Methods : Subjects consisted of 60 children between the ages of 5 and 14 (16 Normal, 24 ADHD, 20 Anxiety Disorder). Neuropsychological tests (KEDI-WISC, CCTT, STROOP, WCST, ROCF) for assessing cognitive and executive function were individually administered to all subjects. Results : There were no significant differences in FSIQ or PIQ among the three groups. However, the ADHD group tended to score lower on the VIQ and subtest of similarity, vocabulary, and digit span tests. The three groups did not significantly differ with respect to CCTT test results. On the STROOP test, the ADHD group showed poor performance on the word, color, and color-word subtests. The three groups did not exhibit significant differences in WCST test results ; however, the anxiety group performed poorly belonging to below 25 percentile rank on perseverative response. On the ROCF test, the ADHD group performed poorly with respect to their organization score and in particular, regarding copy and immediate recall. The anxiety group also performed poorly with regard to organization ; however, this was limited only to immediate recall. Conclusion : Children with ADHD displayed poor inhibition and organizational abilities compared to children with anxiety and normal controls. Further, children with anxiety disorder exhibited low cognitive flexibility and voluntary problem-solving abilities compared to ADHD children and normal controls. Based on these results, we suggest that the characteristics of executive dysfunction in ADHD and anxiety disorder in children are different.

Objective: The purpose of this paper is to introduce a task complexity model combining task design aspects and complexity dimensions and to explain an approach to identifying and organizing task complexity factors based on the model. Background: Task complexity is a critical concept in describing and predicting human performance in complex systems such as nuclear power plants(NPPs). In order to understand the nature of task complexity, task complexity factors need to be identified and organized in a systematic manner. Although several methods have been suggested for identifying and organizing task complexity factors, it is rare to find an analytical approach based on a theoretically sound model. Method: This study regarded a task as a system to be designed. Three levels of design ion, which are functional, behavioral, and structural level of a task, characterize the design aspects of a task. The behavioral aspect is further classified into five cognitive processing activity types(information collection, information analysis, decision and action selection, action implementation, and action feedback). The complexity dimensions describe a task complexity from different perspectives that are size, variety, and order/organization. Combining the design aspects and complexity dimensions of a task, we developed a model from which meaningful task complexity factors can be identified and organized in an analytic way. Results: A model consisting of two facets, each of which is respectively concerned with design aspects and complexity dimensions, were proposed. Additionally, twenty-one task complexity factors were identified and organized based on the model. Conclusion: The model and approach introduced in this paper can be effectively used for examining human performance and human-system interface design issues in NPPs. Application: The model and approach introduced in this paper could be used for several human factors problems, including task allocation and design of information aiding, in NPPs and extended to other types of complex systems such as air traffic control systems as well.

Most leadership styles are generally designed to enhance the cognitive and behavioral skills of leaders with the implicit assumption that this would ultimately translate into high performance. As we are moving towards Industry 4.0, organizations must employ leadership styles that will help the organization succeed. Thus, the objective of this paper is to confirm the determinant factors for Fourth Industrial Revolution (4IR) leadership attributes in Malaysian manufacturing companies. Stratified sampling was used to select the sample. Data was collected using the online survey method, where the response rate was 43 percent. The respondents consisted of respondents aged from 31-40 years old, with 69 respondents. In terms of race, the highest number of respondents are the Malays. Questionnaires were distributed to middle and top-level managers from manufacturing companies which were listed in the Federation of Malaysian Manufacturers (FMM). Confirmatory Factor Analysis (CFA) was used to confirm the reliability and validity of the construct. Based on the analysis, 66 items could be used to measure the 4IR leadership attributes. The validation of 4IR leadership can also provide predictive implications on improving leaders' performance, given the different attributes confirmed by the findings.

The study has its purpose on providing basic resource to enforce the capability of the middle managers by examining the level of performance and the level of awareness about the capabilities of the managers and by understanding the significance of the difference and the reasons for the differences. The source of the study was 195 survey questionnaires that were carried out to the managers of the 9 general hospitals and the method of the analysis was the frequency analysis, analysis of the credibility, matching to sample T-test, independent sample T-test, dispersion analysis, correlation analysis, and multiple linear regression analysis using accumulated variables. The followings are the main result of the study. First, the difference between the level of awareness about the capabilities and the level of performance of the mediator managers in general hospitals had high capability in change management. The following orders were: competence in achievement and behavior, competence in management, competence in recognition, competence in influence, competence in individual effectiveness, and competence in personal relationship service. Second, as the result of the relation analysis in order to understand the correlation between awareness and performance of the mediator managers, everything had significant positive correlation. In the study about the level of importance, the cognitive capability and the management capability had the highest correlation with the correlation number of 0.88. In the study about the level of performance, the cognitive capability, individual capability, and the management capability had the highest correlation with the correlation variable number of 0.79. Third, as the result of studying the reason for the difference between the level of the awareness capability and the level of the performance, lack of the support recognition compensation in the organization level, inappropriate work environment, limit in the regulation were found as the highest reason in the order. As the result of the study, it was concluded that the creation of the efficient capability estimation model and the securement of the system that estimate the capability of the managers should be carried out in order to enforce the capability of the mediator managers in general hospitals.

본 연구는 기업 환경의 불확실성이 증가되고 있는 시점에서 변혁적 리더십과 셀프리더십이 팀 성과에 어떠한 영향을 미치는지를 분석함으로써 팀제의 효용성과 리더십의 중요성에 대한 시사점을 제시하는데 그 목적이 있다. 조직구성원 간에는 교환관계 질을 형성한다는 LMX이론과 사회교환이론 및 경영환경에 적합한 리더십을 발휘해야 한다는 상황이론을 본 연구의 이론적 배경으로 하고 있다. 국내 공기업 9개사를 대상으로 총 166개 팀 880명의 유효 데이터를 활용하여 SPSS 20.0을 이용 회귀분석으로 연구가설을 증명하였다. 연구결과 팀장의 변혁적 리더십은 팀 성과에 긍정적 영향을 미치며, 셀프리더십의 행위전략과 인지전략은 팀장의 변혁적 리더십과 팀 성과 간의 관계를 유의하게 조절하는 것으로 나타남으로써 당초 설정된 연구가설을 모두 채택하게 되었다. 특이한 점은 셀프리더십이 낮은 집단에서 그 효과는 더욱 강하게 나타났다. 본 연구결과가 함의한 바는 팀제 조직에서 팀의 관리자가 셀프리더십이 상대적으로 낮은 집단의 구성원들에게 관심을 갖고 실천할 수 있는 목표를 부여하여 구성원 스스로가 동기부여 될 수 있도록 배려한다면 그렇지 않은 경우와 비교해서 팀 성과는 뚜렷이 향상된다는 것이다.

최근 기업에서는 지속적 경쟁우위를 확보하기 위해 조직 구성원들 간의 네트워크와 신뢰에 의해서 형성되는 사회적 자본을 중시하고 있다. 사회적 자본은 조직 내 다차원적인 요인들과의 상호작용을 통해 구성원들의 적응과 몰입을 유도하고, 의사소통 및 참여의 통로로서 협력적 행동을 유발하여 조직성과를 높이는데 기여한다. 본 연구는 조직 내 형성되어 있는 사회적 자본과 조직지원인식이 이직의도에 미치는 영향을 분석하였으며 나아가 사회적 자본과 이직의도와의 관계에서 조직지원인식의 조절효과를 살펴보았다. 이를 위해 부산 경남 소재 중소 제조업체를 중심으로 설문을 실시하고 위계적 회귀분석을 사용하여 실증 분석하였다. 실증 분석결과, 첫째, 사회적 자본의 구조적 차원과 관계적 차원이 이직의도에 부(-)의 영향을 미치는 것으로 나타났다. 특히 관계적 차원이 이직의도에 큰 영향을 미치는 것으로 나타나 조직 내 구성원들 간의 상호작용을 통한 신뢰형성이 중요함을 알 수 있다. 둘째, 조직지원인식이 이직의도에 부(-)의 영향을 미치는 것으로 나타났다. 이는 구성원 개개인들에게 조직차원의 관심과 전폭적 지원이 필요함을 알 수 있다. 셋째, 조직지원인식이 사회적 자본과 이직의도 사이의 관계를 조절하는 것으로 나타났다. 조직지원인식이 높을수록 사회적 자본의 관계적 차원만이 이직의도에 미치는 부(-)의 영향이 더욱 낮게 나타나는 것으로 확인되었다. 이러한 분석결과를 근거로 본 연구의 이론적 실무적 시사점과 향후연구 과제에 대하여 논의하였다.
