SCM은 원자재를 공급받아 이를 완제품으로 만들고, 최종소비자에게 판매하는 일련의 사업단위를 관리하는 기법이다 즉, 주문창출, 주문접수, 주문이행 그리고 상품, 서비스 및 정보의 유통, 협력을 포함한 총괄적인 개념의 용어이다. 또한 원자재의 공급자에서부터 최종소비자까지 연결하는 생산의 흐름을 최적으로 운영하고 조율하는 것이 SCM의 목적이다. Supply Chain상에는 여러 개의 다른 조직체와 활동에 필요한 많은 기능(설계, 생산, 조달, 운송 등)이 존재하며, 전체 Supply Chain의 효율성을 증가시키기 위하여 실물, 정보, 자금을 최적으로 관리하는 것이 SCM의 역할이다. 본 논문에서는 이러한 SCM의 근간이 되고 있는 EDI의 조달시스템에 초점을 맞추어 가상 시나리오를 세우고, 업무를 분석하여, 데이터베이스를 설계하고, 마지막으로 웹상에서의 페이지들을 개발하고 이들을 연결하여서 최종적인 시스템을 구현하였다.

This study aims to identify the factors influencing the perofrmance of agricultural projects for small farmers in Malawi. This cross-sectional study was conducted to discover the factors behind the slow performance of agricultural projects in alleviating poverty. The research was conducted in the Karonga and Phalombe Districts in the northern and southern parts of Malawi, respectively. The data were collected through a structured questionnaire survey administered to 82 agriculture extension workers, and a multiple regression analysis was conducted. The results indicated that farmers' socioeconomic factors, including high illiteracy and poverty rates, poor participation regarding project implementation, and high dependency syndrome, significantly affected the performance of agricultural projects. Within the projects them selves, this study discovered that there was no consistent flow of funds. This greatly affected the schedule of project activities, thereby compromising performance. The study recommends that the government and all relevant stakeholders work jointly to alleviate poverty. It is especially important to ensure that smallholder farmers are equipped with self-help capabilities. In addition, it is critical to examine the issues of funding disbursement.

This paper finds that Korean zero-leverage firms are not homogeneous. By conducting both univariate and multivariate logit regression analysis, this paper finds that Korean zero-leverage firms have zero leverage as either a consequence of financial constraints or because of a strategic decision to mitigate under-investment incentives and preserve financial flexibility. There are two distinct groups of unlevered firms with different levels of constraints as measured by their dividend policy, namely dividend payers and non-payers. Importantly, this paper finds new evidence that these two groups have different motives for selecting a zero leverage policy. Firms in the first group (non-payers) have zero leverage, mainly due to financial constraints. They rely heavily on their internal funds and consequently invest in fewer growth opportunities than their levered counterparts. Firms in the second group (payers) deliberately avoid debts and preserve financial flexibility to mitigate investment distortions, as predicted by the under-investment and financial flexibility hypotheses.

Recently construction companies' capital condition has been aggravated due to low profit, fierce competition and market contraction. For this reason, the companies rely on public construction projects that protect construction fee by regulations. Despite these regulations, problems regarding progress payment are constantly happening. Also, insufficient analysis on interaction between contractors makes policy making difficult. Thus, in this study, interaction between contractors are quantitatively determined according to delay of application and payment based on current public construction regulations on construction stage. A system dynamics model is used, which analyzes the problems based on an interaction between contractors, and solutions for progress payment application and payment delay are suggested according to the research results.

This study investigates the correlation between financial constraints and investment activities in Korean logistics firms. A sample of 340 companies engaged in the transportation sector, as per the 2021 KSIC, was selected for analysis. Financial data obtained from the DART were used to compile a panel dataset spanning from 1996 to 2021, totaling 6,155 observations. The research model was validated, and tests for heteroscedasticity and autocorrelation in the error terms were conducted considering the panel data structure. The relationship between investment activities in the previous period and current investment activities was analyzed using panel Generalized Method of Moments(GMM). The validation results of the research indicate that Korean logistics firms tend to increase investment activities as their level of financial constraints improves. Specifically, a positive relationship between the level of financial constraints and investment activities was consistently observed across all models. These findings suggest that investment decision-making varies based on the financial constraints faced by companies, aligning with previous research indicating that investment activities of constrained firms are subdued. Moreover, while the results from the model examining whether investment activities in the previous period affect current investment activities indicated an influence of investment activities from the previous period on current investment activities, the investment activities from two periods ago did not show a significant relationship with current investment activities. Among the control variables, firm size and cash flow variables exhibited positive relationships, while debt size and asset diversification variables showed negative relationships. Thus, larger firm size and smoother cash flows were associated with more proactive investment activities, while high debt levels and extensive asset diversification appeared to constrain investment activities in logistics companies. These results interpret that under financial constraints, internal funding sources such as cash flows exhibit positive relationships, whereas external capital sources such as debt demonstrate negative relationships, consistent with empirical findings from previous research.

In this study, the rate of return on investment used as a proxy variable for the entity's value and financial structure (liability ratio) is related to positive balance. This is consistent with the Static Tradeoff Theory (STT) that the entity's value and financial structure are related to a positive balance because the capital expense of a debt (tax-saving effects) that is less than its equity cost before it is in financial difficulty. Also, operating profitability (EBITDA/Sales), investment safety, total asset growth, net working capital and depreciation expenses are related to negative (-) with financial structure (liability ratio). This is the result of an analysis consistent with the Pecking Order Theory (POT). Fuel costs, borrowing, total asset turnover, financial costs, and tangible asset ratios have a significant positive relationship with the debt ratio. This is consistent with the agency theory and confirms that excessive chartering expenses, such as the bankrupt H company, are the main factors that pressure the financial structure of Korean ocean carriers.

In this paper, we analyse empirically the effects of financial characteristics on the relationship between R&D investment and market value of firms listed on Korea Exchange. The main results of this study can be summarized as follows. Firm size increase the market valuation of R&D investment because it provides economies of scale, easier access to capital market, and R&D cost spreading. Market share also positively effects the relationship between R&D investment and firm value. Alternatively, free cash flow has a negative effect on the relationship between R&D investment and firm value because firms with high free cash flow could be tempted to use the free cash flow to undertake negative NPV projects. The dependence on external finance is a handicap negatively assessed by the market when firms undertake R&D projects due to the higher information asymmetry associated with this kind of project. Labor intensity has a negative effect on the relationship between R&D investment and firm value because the abnormal profits arising from R&D investment are diluted among employees. Capital intensity also has a negative effect on the relationship between R&D investment and firm value due to the greater financial constraints faced by capital intensive firms. In conclusion, several financial characteristics(firm size and market share) positively effect the relationship between R&D investment and firm value, while others(free cash flow, dependence on external finance, labor intensity, and capital intensity) exert a negative effect. Therefore, we conclude that the effectiveness of R&D investment depends on these financial characteristics.
