스마트워크 후 조직 문화 변화 연구: 서비스 대기업 ‘H사’ 사례

장민제 ( Minje Jang ),남은우 ( Eunwoo Nam ),이정우 ( Jungwoo Lee ) 한국지식경영학회 2021 지식경영연구 Vol.22 No.1

최근 코로나 19의 세계적 대유행 이후로 비즈니스 업무환경이 스마트워크로 급격하게 변하고 있다. 스마트워크는 기본적으로 언제 어디서나 일을 할 수 있는 시스템을 근간으로 하고 있다. 스마트워크가 성공하기 위해서는 이러한 시스템의 구축과 운영 문제가 중요할 뿐만 아니라, 스마트워크 도입이 미치는 조직문화에의 영향을 연하는 것도 중요하다. 본 연구에서는 한국의 레저 서비스 대기업인 H사에서 경영상 강조하고 있는 조직 문화의 일곱 가지 차원 - 전략적 혁신성, 조직 유연성, 공정한 인사관리, 합리적 의사결정, 조직 활력, 신뢰 협력, 리더십 - 에 있어서 스마트워크 전후로 어떤 변화가 있는지 설문과 인터뷰를 통하여 조사하였다. 조사결과 전략적 혁신성, 조직 유연성, 조직 활력, 신뢰 협력의 네가지 차원에서는 직원들의 평가가 통계적으로 낮아진 것으로 나타났고, 공정한 인사관리, 합리적 의사결정, 리더십의 측면에서는 큰 변화가 없는 것으로 나타났다. 도입초기 단기적 현상일수도 있어 앞으로의 변화도 관찰할 필요가 있지만, 기업 관점에서 궁극적으로 유연한 업무 환경의 변화를 추구하는데 있어서 직원들로 하여금 전략적 혁신성, 조직 유연성, 조직 활력, 신뢰 협력과 같이 경영상 중요한 조직 문화의 측면에서 적극적으로 준비하고 대응하는 것이 필요함을 시사한다. 조직 활력이 상대적으로 낮아지고, 조직구성원간 신뢰 소통과 협력은 감소하는 것은 굉장히 부정적 변화로서 적극적 관리가 필요하다. 이어진 인터뷰에서는 스마트워크 도입의 성공적 정착을 위해서는 리더십의 역할이 중요하게 나타나고 있어, 향후 일하는 방식의 변화에 따라 경영진 리더십의 역할이 더욱 강조될 것이라는 것을 시사하였다. While there is a rapid transition to smart work due to COVID-19, not many studies have measured the changes in organizational culture after firm-wide institutionalization of smart work. Through a questionnaire and a series of stakeholder interviews, this study examined how and to what extent employees’ perception of organizational culture changed after the introduction of smart work in a large leisure service company H in South Korea. The working culture of the organization is measured as the changes in the organizational members’ perception on seven dimensions: strategic innovativeness, organizational flexibility, fair human resource management, rational decision making processes, organizational vitality, trustful collaboration, proactive leadership. The results demonstrated that, after the introduction of smart work, the organizational members’ perception on strategic innovativeness, organizational flexibility, organizational vitality, trustful collaboration have declined significantly while the changes in fair human resource management, rational decision making processes, and proactive leadership are insignificant. Though found to be insignificant, follow up interviews revealed that participants think that the role of management leadership is very critical for the smart work systems to be institutionalized successfully. While the smart work may have different effects depending upon industry or organizational characteristics, this study present a case for changes in organizational culture after institutionalizing smart work. Implications are discussed with further research issues at the end.

Background: Patients with corticosteroid (CS)-dependent asthma have higher mortality than those with CS-independent asthma. However, the common causes of mortality and cause-specific mortality risk in this population have not been well elucidated. Methods: We performed a population-based 1:1 matched cohort of patients with CS-dependent asthma (CSuse> 6 months during baseline period) (n=8,334) and CS-independent asthma (CS-use<6 months during baseline period) (n=8,223) using the Korean National Health Insurance Services (NHIS) data.We determined hazards ratios (HRs) and 95% confidence intervals (CIs) for each cause of mortality. We also performed a cause-specific and subdistribution proportional hazards regression model to account for competing risks caused by mortality from other causes. Results: The overall mortality was 5,191/100,000 person-years during a median of 9.5 years (interquartile range, 5.5-9.9 years) of follow-up. All-cause mortality was higher in the CS-dependent cohort than in the CS-independent cohort (6,760/100,000 versus 3,833/100,000 person-years, p<0.001). The common causes of mortality in patients with CS-dependent asthma were respiratory diseases (46.3%), cardiovascular diseases (17.7%), malignant neoplasms (14.2%), injury, poisoning, and external causes (4.8%), and endocrine diseases (3.5%). Compared with patients in the CS-dependent cohort, those in the CS-dependent cohort were more likely to die due to the following causes; respiratory diseases (HR=3.12, 95% CI = 2.85-3.42), cardiovascular diseases (HR=1.28, 95% CI=1.15-1.43), malignant neoplasms (HR=1.14, 95% CI=1.01-1.28), injury, poisoning, and external causes (HR=1.40, 95% CI=1.13-1.74), and endocrine diseases (HR=1.71, 95% CI=1.30-2.23). When considering competing risks caused by mortality due to other diseases, mortality risks were especially significant for chronic respiratory diseases (subdistribution HR=2.96, 95% CI=2.70-3.24) and endocrine diseases (subdistribution HR=1.49, 95% CI=1.14-1.95). Conclusions: The common causes of mortality in CS-dependent asthma were respiratory diseases, cardiovascular diseases, malignancy, injury, poisoning, and external causes, and endocrine diseases. Compared with CS-independent asthma patients, CS-dependent asthma patients had higher disease-specific mortality risk for respiratory diseases and endocrine diseases.

Comorbid bronchiectasis increases the mortality of corticosteroid-dependent asthma

( Hyun Lee ),( Jiin Ryu ),( Eunwoo Nam ),( Min Ju Jo ),( Sung Jun Chung ),( Yoomi Yeo ),( Dong Won Park ),( Tai Sun Park ),( Ji-yong Moon ),( Tae-hyung Kim ),( Jang Won Sohn ),( Sang-heon Kim ),( Ho J 대한결핵 및 호흡기학회 2019 대한결핵 및 호흡기학회 추계학술대회 초록집 Vol.127 No.-

Background: Bronchiectasis is a common comorbid condition in patients with severe asthma, of whom up to two-thirds are corticosteroid (CS)-dependent. However, there are uncertainty whether comorbid bronchiectasis is associated with long-term mortality in patients with CS-dependent asthma. Methods: Using data from the Korean National Health Insurance Services (NHIS), a population-based 1:1 matched cohort of patients with CS-dependent asthma (CS use > 6 months during baseline period) (n = 8,334) and CS-independent asthma (CS use < 6 months during baseline period) (n = 8,223) was performed. Each group was further subclassified according to the presence or absence of bronchiectasis. Hazard ratios (HRs) with 95% confidence intervals (CIs) for all-cause mortality among CS-dependent asthma patients with bronchiectasis, CS-dependent asthma patients without bronchiectasis, and CS-independent asthma patients with bronchiectasis relative to CS-independent asthma patients without bronchiectasis were evaluated. Results: In both CS-dependent and CS-independent cohort, those with bronchiectasis were more likely to be older (p = 0.020), receive medical aid as a type of insurance (p < 0.001), and have higher Charlson comorbidities index (p < 0.001). Compared with patients without bronchiectasis, those with bronchiectasis were more likely to have metabolic diseases (p < 0.001), pulmonary infectious diseases (p < 0.001), and cardiovascular diseases (p = 0.041). There was no significant increased HR for mortality in CS-dependent asthma patients with bronchiectasis relative to CS-dependent asthma patients without bronchiectasis (HR = 1.18, 95% CI = 0.92-1.50). However, CS-dependent asthma patients with bronchiectasis and those without bronchiectasis were 2.18 (95% CI = 2.041-2.33) and 2.32 (95% CI = 1.92-2.81) times higher mortality compared with CS-independent asthma patients without bronchiectasis, respectively. Conclusion: Comorbid bronchiectasis is associated with increased mortality risk in patients with CS-dependent asthma.

Understanding Comprehensive Transcriptional Response of Salmonella enterica spp. in Contact with Cabbage and Napa Cabbage

( Hojun Lee ),( Seul I Kim ),( Sojung Park ),( Eunwoo Nam ),( Hyunjin Yoon ) 한국미생물생명공학회(구 한국산업미생물학회) 2018 Journal of microbiology and biotechnology Vol.28 No.11

Salmonellosis is commonly associated with meat and poultry products, but an increasing number of Salmonella outbreaks have been attributed to contaminated vegetables and fruits. Enteric pathogens including Salmonella enterica spp. can colonize diverse produce and persist for a long time. Considering that fresh vegetables and fruits are usually consumed raw without heat treatments, Salmonella contamination may subsequently lead to serious human infections. In order to understand the underlying mechanism of Salmonella adaptation to produce, we investigated the transcriptomics of Salmonella in contact with green vegetables, namely cabbage and napa cabbage. Interestingly, Salmonella pathogenicity island (SPI)-1 genes, which are required for Salmonella invasion into host cells, were up-regulated upon contact with vegetables, suggesting that SPI-1 may be implicated in Salmonella colonization of plant tissues as well as animal tissues. Furthermore, Salmonella transcriptomic profiling revealed several genetic loci that showed significant changes in their expression in response to vegetables and were associated with bacterial adaptation to unfavorable niches, including STM14_0818 and STM14_0817 (speF/potE), STM14_0880 (nadA), STM14_1894 to STM14_1892 (fdnGHI), STM14_2006 (ogt), STM14_2269, and STM14_2513 to STM14_2523 (cbi operon). Here, we show that nadA was required for bacterial growth under nutrient-restricted conditions, while the other genes were required for bacterial invasion into host cells. The transcriptomes of Salmonella in contact with cabbage and napa cabbage provided insights into the comprehensive bacterial transcriptional response to produce and also suggested diverse virulence determinants relevant to Salmonella survival and adaptation.
