대량생산체제를 위주로 했던 산업혁명 초기에는 원가계산방식이 비교적 수월하였다. 생산에 투입된 비용을 그대로 생산량으로 나누기만 하면 되었고 이 수치를 그대로 원가라고 간주하여도 기업이 존속하는데는 아무 영향이 없었다. 물론 이 때에도 간접비라는 것은 존재하였으나 그 비중이 미미했기에 이를 무시하여도 되었던 것이다. 그러나 그 때와 달리 지금은 기업환경은 다품종 소량생산, 고객 주문 생산 등의 다양한 형태로 변화되어 왔으며 유연생산시스템, 적시생산시스템 등과 같은 새로운 경영기법 및 생산관리 기법이 발달함에 따라 그간 무시되어 왔던 간접비가 오히려 직접비보다도 많아지는 현상이 생기게 되었다. 그래서 증가하는 간접비를 효과적으로 제품이나 서비스에 배부하여야 하는 필요성에서 연구가 시작되었고 그 결과로서 나온 원가계산방법이 활동기준원가계산시스템이다. 우리 나라에는 90년대 초반에 도입되어 여러기업이 시스템을 구축한 상태이며 이에 대한 사례를 연구한 논문도 발표되었다. 활동기준원가 계산시스템이 기존의 원가계산시스템보다 더 정교하다는 것은 많은 이미 많은 연구들에서 입증이 되었지만 그래도 실제 시스템의 구축에 있어서는 아직도 많은 연구과제가 남아있다. 본 연구는 시스템의 구축과정에서 핵심과정으로써 반드시 거쳐야 하는 활동분석단계에 관심을 두고 활동분석과정을 가능한 적은 비용으로 빠르게 수행하기 위한 방법을 모색하였다. 그 방법으로 선택한 것이 기존의 기업보유자료를 이용하여 활동분석을 수행하는 것으로 비록 활동분석데이터의 신뢰성에는 조금 부족한 면이 있을 수 있으나 기업보유자료가 활동분석과 개연성이 있음을 제시하고자 하였다. 한다.드가 전송한 패킷은 이전 셀 지역에 있는 에이전트가 새로운 셀 지역에 있는 이동 노드로 패킷을 재전송하여 전달하는 smooth 핸드오프 기능을 제공한다. 이전 셀 지역에 속한 외부 에이전트가 바인딩을 갱신하기 전에 송신 노드로부터 이동노드로 전달된 패킷이 있을 경우는 패킷을 저장하여 이후에 이동 노드의 위치 정보에 관한 바인딩 정보가 갱신되면 이러한 바인딩 정보에 따라 패킷을 재전송하는 버퍼기능도 제공한다. route optimization mobile IP는 기본적인 mobile IP에서의 복잡한 라우팅 문제를 해결하고, 핸드오프에서의 패킷 손실률을 최소화 한다.본 논문에서는 컴퓨터 시뮬레이션을 통해 smooth 핸드오프를 이용한 mobile IP의 성능을 분석한다. 일반적으로 데이터 트래픽 특성, 노드의 이동성, 바인딩 갱신시간, 버퍼관리 방법 등은 핸드오프 동안 mobile IP의 성능에 많은 영향을 미친다. 따라서 시뮬레이션 모델을 이용하여 다양한 트래픽 환경에서 위에 언급된 성능 파라미터들의 영향을 분석한다. 마지막으로 시뮬레이션 결과를 이용하여 mobile IP의 성능을 개선시키기 위한 방법을 제시한다. 제시하고자 한다.과로 여겨지며, 또한 혈청중의 ALT, ALP 및 LDH활성을 유의성있게 감소시키므로서 감잎 phenolic compounds가 에탄올에 의한 간세포 손상에 대한 해독 및 보호작용이 있는 것으로 사료된다.반적으로 홍삼 제조시 내공의 발생은 제조공정에서 나타나는 경우가 많으며, 내백의 경우는 홍삼으로 가공되면서 발생하는 경우가 있고, 인삼이 성장될 때 부분적인 영양상태의 불충분이나 기후 등에 따른

The importance of trade cooperation with foreign countries is becoming higher in order to utilize the competitiveness of its own country's industries. In Korea, the government has made various efforts to respond to the expansion of foreign trade cooperation. As time goes by, it is needed to redefine and reestablish the functions of industrial polices in order to improve the effectiveness and efficiency of foreign trade cooperation. We focus on the industrial and trade policies related to FTA. Mainly we do research the impact (before and after FTA) of industry, trade policies, and firms' management activities on the export-oriented firms. For this end we conduct a survey on the firms' evaluation of the trade related policies and analyze with the panel data regression model. According to the results, in order to enhance the utilization of FTA, the connection with export support program, the training of expert HRs, and the prohibition of double regulation are the main influential policies.

This study analyzed statistically the determinants that affect the royalties of knowledge technology transfer, which accounts for a considerable portion of university technology transfer. As knowledge technology transfer certainly includes a move from tacit knowledge from one side to the other side per se, the scope of knowledge technology transfer is unclear and numerical information of technology transfer, such as research fund scale, which is used widely in previous studies, cannot be used in the analysis. Therefore, this study focused on the researcher characteristics and included its explanatory variables in the present study. In addition, it included the technical characteristics of the knowledge transferred and the characteristics of the contracting company. The knowledge maturity calculated from the appointment year and contract date positively affects the technology royalties, but work experience and patent activity of the researcher are not statistically significant. Statistically significant differences in the technology royalty according to the type of technology transfer and the company location were observed, but there was no meaningful change in the technology royalty depending on the technical field and company business scale.

We analyze the effects and related factors of Smart Factory adoption. 110 and 325 samples were collected by median-size-industry matching method, respectively, of adopting and non-adopting companies. We use financial statement data (ROA, etc.) from the year before adoption to the fourth year after adoption. Abnormal operating performance and annual abnormal changes are obtained according to event study method, and analyzed by Wilcoxon signed-rank test and t-test. ROA and sales growth rate demonstrate short-term effects after adoption, but not long-term effects. As a result of regression analysis to examine if the three factors of labor intensity, R&D intensity, and prior financial performance have moderating effect, the moderating effect of R&D intensity and prior financial performance is confirmed. In addition, we perform regression analysis to confirm performance effects of early and late adoptions and whether prior financial performance and organization size have moderating effect. It is confirmed that the later the time of adoption, the greater the effect of adoption in the long term and the moderating effect of prior financial performance and organization size is confirmed.

In a business context, ESG is defined as the use of environmental, social, and governance factors to assess a firm's progress in terms of sustainability. Social media has enabled the public to actively share firms' good and/or bad deeds, increasing public interest in ESG management. Therefore, this study aimed to investigate the association of firm performances with the respective sentiments towards each of environmental, social, and governance activities, as well as comprehensive ESG sentiments, which encompass all environmental, social, and governance sentiments. This study used panel regression models to examine the relationship between social media ESG sentiment and the Return on Assets (ROA) and Return on Equity (ROE) of 143 companies listed on the KOSPI 200. We collected data from 2018 to 2021, including sentiment data from a variety of social media channels, such as online communities, Instagram, blogs, Twitter, and other news. The results indicated that firm performance is significantly related to respective ESG and comprehensive ESG sentiments. This study has several implications. By using data from various social media channels, it presents an unbiased view of public ESG sentiment, rather than relying on ESG ratings, which may be influenced by rating agencies. Furthermore, the findings can be used to help firms determine the direction of their ESG management. Therefore, this study provides theoretical and practical insights for researchers and firms interested in ESG management.

The technological innovation of high-tech enterprises plays a positive driving role in operational performance. Investigating the factors influencing the operational performance of high-tech enterprises and the effects of technological innovation on operational performance is a targeted approach to promoting the growth of economic benefits and enhancing the foundation of enterprise efficiency. Additionally, it holds positive significance for the increase in market share of high-tech enterprises. This paper, considering the characteristics of high-tech enterprises, selects three influencing factors: research and development (R&D) investment intensity, the number of authorized patents, and the increment of intangible assets. Theoretical analysis is conducted on the impact mechanism and effects of these factors on operational performance. Based on this, empirical analysis is performed using relevant data of Chinese high-tech enterprises from 2011 to 2019. The study indicates that R&D investment intensity has a significant positive promoting effect on operational performance, the number of authorized patents also positively influences operational performance significantly, while the asset-liability ratio of high-tech enterprises has a notable inhibitory effect on operational performance. Finally, relevant recommendations are proposed.
