Generally the SCM system is implemented on the basis of ERP system. So it is necessary to find out the relationships between these two Information systems to make sure that the SCM system is implied successfully in the company. The goal of this paper is to find out how the Enterprise Resource Planning system's maturity affects on the implementation intension of Supply Chain Management system in manufacturing companies in korea. To achieve this goal, the empirical research about influence of ERP system on SCM system was carried out. The result of this research can be usefully referred in decision making process for the successful implementation of the SCM system in manufacturing company.

  • 본고(本稿)는 세수증대(稅收增大)가 충분치 않은 경우 재정적자(財政赤字)를 충당하기 위한 국채발행(國債發行)은 본원통화(本源通貨)의 증대가 뒤따르지 않을 경우에도 물가를 즉시 상승시킬 수 있음을 정부(政府)의 동태적(動態的) 예산제약(豫算制約)이 나타내는 단순한 산수(算數)를 이용해서 보여주고 있다. 본고(本稿)가 가정하는 상황(합리적(合理的) 기대(期待), 정확(正確)한 정보(情報) 등)에서는 정부의 예산제약(豫算制約)을 동태적(動態的)으로 계속 연결해서 얻을 수 있는 실제의 동태적(動態的) 예산제약식(豫算制約式)을 검증할 수 있는 형태의 식으로 대체할 수 있다. 이 새로운 예산제약식(豫算制約式)에 의하면 미래잉여금(未來剩餘金)의 기대액(期待額)이 변하지 않는 상태에서의 국채발행(國債發行)은 즉각적으로 현재의 물가상승(物價上昇)을 유발(誘發)하고, 미래잉여금(未來剩餘金)의 기대액(期待額)의 감소(減少)(미래재정적자를 포함) 또한 같은 결과를 초래한다. 전후(戰後) 미국(美國)과 주요공업국가(主要工業國家)의 시계열자료(時系列資料)를 벡터자기회귀분석방법(自己回歸分析方法)에 의해서 분석한 결과 이들 잘 발달된 자본시장(資本市場)을 가진 나라에서는 본고(本稿)의 이론(理論)과 부합(符合)되게 물가(物價)와 국채(國債) 그리고 잉여금(剩餘金)이 변동해 왔음을 알 수 있다. 한국(韓國)의 자본시장여건(資本市場興件)이 현재는 이들 국가와 다르지만 곧 근접해 갈 것이 기대되므로, 앞으로 재정적자(財政赤字)를 국채발행(國債發行)에 의해서 조달해야 할 경우 물가(物價)에 대한 파급효과(波及效果)를 감안해서 세수(稅收)의 확대(擴大)가 뒤따르는 경우에 한하도록 하여야 할 것이다.

  • The hydrodynamic behaviors of the clarifier with an interior baffle in a wastewater treatment plant was investigated by using a radiotracer $^{99m}Tc$(30 40 mCi) to verify the results of CFD(computational fluid dynamics) modelling in the previous study. The clarifier model was manufactured with consideration to the hydraulic similarity(1/21) of a real plant($L{\times}W{\times}H:2.6{\times}0.4{\times}0.2m$). By installation of an interior baffle to the clarifier, the strong density current at the bottom of the clarifier decreased substantially and increased the area of sludge settling zone, which were visualized successfully from the radiotracer experiment. Also the portion of short circuit stream changed from 48 % to 32 % and the mean residence time of sludge decreased from 940 sec to 810 sec, which corresponds to the results of CFD modelling. As a result, it is anticipated that radiotracer technology can be used as an important tool for designing new wastewater treatment plants and verifying their performances after structural modifications.

  • The purpose of this study is to provide academic basic data by identifying the effects of active seniors' online video physical activity on physical self-perception and successful aging. In order to achieve the purpose of this study, 10 active seniors in D city were selected, and after receiving consent to participate in online video physical activity, it was divided into pre and post, and from March 14 to April 22, 2022, Kakao Talk group chat was opened to watch online physical activity videos during the 12th session, download 2 videos a week, and exercise from Monday to Friday. To solve the research problem, frequency analysis and paired t-test were conducted using the SPSS Ver20.0 statistical program. As a result, first, as a result of analyzing the pre- and post-tests of physical self-perception through physical activity of active seniors, all of face satisfaction, body satisfaction, change in physical strength, and change in disease increased on average. Second, as a result of pre- and post-analysis of active seniors' successful aging through physical activity, acceptance of others, orientation toward self-fulfillment, self-acceptance, and satisfaction with children increased, but autonomous life and active participation in life decreased. Through these results, in the COVID-19 period, when activities were restricted due to social distancing, active seniors' online video physical activity has a positive effect on physical self-perception and successful aging, and various programs that can be active on their own should be developed in the future.

  • This study examined the effect of leadership competence on job embeddedness among child co-residence workers to mitigate the negative impact of human resource management on their low job tenure and treatment. The study initially tested the mediating effects of social capital and organizational culture between the two variables, thereby suggesting ways to enhance job attendance among workers in children's shared family homes. The results of the study are as follows. Leadership competencies among child co-residence workers were found to have a positive effect not only on job embeddedness but also on social capital and organizational culture. Social capital and organizational culture were identified as mediators in the relationship between leadership competencies and job commitment The primary significance of this study lies in its identification of the relationship between leadership competence and job attendance - a factor previously overlooked. This finding offers a pathway to increase job attendance. Furthermore, the study expands the scope of relevant variables to include leadership competence, social capital, and organizational culture. Finally, it sheds light on the mediating effects of social capital and organizational culture on the relationship between leadership competence and job embeddedness.
