This paper deals with the productivity increment through construction of lean production system for automobile factory in China. This lean production system has been progressed according to 5 steps. Step 1 is the work preparation. Step 2 is the process design. Step 3 is the establishment of method to count production quantity. Step 4 is the establishment of measuring method for input and output. Finally, step 5 is the construction of flexible production system able to adapt for environment change. This lean production system is expected to obtain the productivity increment by 50% for plastic plant and reduction by 50% in inventory quantity.

The purpose of this study was to develop and validate a scale for the multidimensional assessment of work-family spillover in working couples with children. The subjects of this study were working wives and husbands with children in Daegu. Two surveys were administered, eliciting 243 respondents and 227 respondents, respectively. Then a series of tests were run to analyze the data, including item-to-total correlation, Cramer's V coefficients, item discrimination, Cronbach's ${\alpha}$, and exploratory and confirmatory factor analysis. The results yielded that, first, a preliminary 102 items were developed on the basis of the literature review, and this was narrowed down to 72 items selected with the help of experts. Through preliminary, primary and secondary survey analysis, the scale for the multidimensional assessment of work-family spillover was developed and validated, with a 36 items scale, 18 items for work to family spillover and 18 items for family to work spillover. Furthermore, the scale constructed three spillover processes - time interference, energy depletion, and psychological distraction - and consisted of four different domains of family life into which spillover occurs - namely marital relationship, parent-child relationship, leisure, and housework. The internal reliability was evaluated to show a confidence range of .85 ~.92 for each factor.

Six sigma is focused on quality improvement through variation reduction, while lean is on process flow improvement and lead time reduction by waste elimination. However, lean cannot bring a process under statistical control and six sigma alone cannot dramatically improve process speed. Lean six sigma was developed to achieve faster rate of improvement in customer satisfaction, cost, quality, process speed, and invested capital. In this paper we present the importance of using value stream mapping and suggest a guideline on how to integrate lean and six sigma by is proposed.

금융기관의 지식경영 초기 단계 이후부터는 지속적인 지식 창출과 효율적인 지식 검색이 지식경영의 핵심 요인으로 보고, 지식 창출의 한 방안으로 e-러닝을 제시하고, 효율적인 지식 검색 체제를 구축하기 위해서 리포지토리에 저장된 학습객체, 지식객체, 자료실 정보객체를 유사성에 따라 분류하고 상호 연관관계를 맺음으로써 키워드 검색은 물론 분류 검색과 연관 검색을 가능하게 하는 토픽맵 개념에 기반을 둔 지식맵을 활용한 통합 리포지토리 모형을 제안해 보았다. 모형 구현을 위해서 사용된 연구 방법에는 지식 관리 현황을 파악하기 위해서 세 보험회사들을 대상으로 사례 연구를 실시하였고, 기존의 토픽맵 기반의 실험적인 정보시스템들도 분석, 참조하였다. 디렉토리 형식의 전통적인 지식맵은 관련된 지식을 연계시키기가 어려워 지식관리시스템의 효율적인 브라우징이나 검색에 걸림돌로 작용하고 있는데 본 연구에서 제안된 모형은 이러한 문제점들을 개선할 하나의 안으로 이용될 수 있을 것이다.

The purpose of this study was to investigate the relationship between household income, consumption wants for education, private education expenses, and old-age economic preparation behaviors in mothers with school-aged children. The participants in this study comprised 393 mothers living with children aged 8.19 in Daegu. All participants had wage-earning husbands. A questionnaire was used to collect the data. Factor analysis was conducted using SPSS and structural regression analysis was performed using AMOS. The main results of this study were as follows: The participants' old-age economic preparation behaviors were influenced by their household income, the proportion of private education expenditures they paid, and the perceived burden the participants had of these private education expenditures. The consumption wants for education in mothers with school-aged children had no significant impact on the proportion of private education expenditures paid by the participants. Household income, proportion of private education expenditures, and perceived burden of the private education expenditures had a direct effect on the old-age economic preparation behaviors of the participants. When the perceived burden of the private education expenditures was mediated, the consumption wants for education in mothers with school-aged children had an indirect effect on their old-age economic preparation behaviors.

글로벌 경쟁의 심화, 빠른 기술의 발달, 그리고 짧아진 제품 수명주기는 제조기업들이 고객과 경쟁환경의 변화에 빠르게 적응하는 것을 요구하고 있다. 린생산과 민첩 생산이 지난 20년간 제조 기업의 효율성과 효과성을 높이는데 중요한 전략으로 사용되어 왔다. 본 연구에서는 민첩성의 선행요인이 무엇인지를 선행연구를 통해서 살펴보고 이들 요인들이 민첩성에 미치는 영향과 민첩성이 경영성과에 미치는 영향을 구조방정식 모형을 통해 실증 분석하였다. 실증분석의 결과 조직내 협력, 조직간 협력, 상호간 신뢰는 민첩성에 유의한 영향을 미치지만 정보 공유는 유의성이 없는 것을 알 수 있었다. 그리고 민첩성은 운영성과와 전략적 성과에 유의한 영향을 미친다는 것을 알 수 있었다. 공급사슬 프로세스의 성과와 경쟁력 향상을 위해서는 민첩성이 무엇보다 중요하다는 사실을 확인하였다는 점에 본 연구가 공헌한 바가 있다.

Food delivery service combined with IT technology and HMR (Home Meal Replacement) are rapidly growing due to the COVID-19. Recently, the demand for salads along with HMR has increased among office workers in their 20s and 30s who are interested in health and beauty. Freshcode is a food startup with 6 years of experience that started selling salad products through O2O service. Freshcode applied for a patent for a service that collects orders from nearby areas and delivers them on the same day to a designated delivery address 'FCOSPOT' to save shipping costs. In March 2021, in recognition of the growth potential of the regular delivery service, Freshcode received an investment of 6 billion won in Series A. This study may have practical implications to early-stage startups and scale-up stage startups through a longitudinal case study on the growth of a single company. As for the research method, the lean startup methodology and lean canvas were used in the early stage of startup. In particular, the process of the build-measure and learn feedback-loop, which is the core of lean startup methodology, was applied to each major decision-making step. In the scale-up stage after 5 years, the business model canvas was used to schematize the growth as a food online O2O platform to verify continuous innovation. This case study has three main findings. First, the idea of 'FCOSPOT' was successfully implemented through the Lean Startup methodology. Second, Freshcode demonstrated the scalability of the differentiated business model of shared base delivery O2O. Third, a key factor of success was the digital integrated communication operation strategy that maximizes the experience for the created customers.
