  • Normally, the single wall(SW) corrugated board has more advantages than double wall (DW) corrugated board in terms of the cost of the materials and logistics. For instance, the SW corrugated board has 3 layer papers whereas the DW corrugated board has 5 layer papers. The thickness of the SW is about 5mm, but that of the DW is 8mm. Accordingly, the SW corrugated board is quite more used in the developed countries than the DW corrugated board. But in Korea, the DW corrugated board is quite more used. The reason why more DW corrugated board are used than the SW corrugated in Korea is that in order that the SW corrugated board has the same box compression strength as DW corrugated board, the cost of the SW corrugated board is higher than that of the DW corrugated board because the virgin kraft liners are all imported from overseas. In this study, the physical properties such as flat crush strength and column crush strength of typical SW corrugated board and single wall dual-layer medium corrugated board and their costs were analyzed. The analysis resulted in that single wall dual-layer medium corrugated board has the same thickness as the SW corrugated board but the more flat crush strength and column crush strength and the less cost than the SW corrugated board.

  • The study aims to investigate factors that determine dividend payout policy using 336 non-financial firm year observations covering the period 2005 to 2016 in Malaysia. We found a significant positive relationship between corporate board size, board members average age, board tenure and dividend payout policy. We also found a strong negative effect and statistically insignificant relationship of board diversity, board independence, CEO duality and dividend payout policy. Additional, financial leverage has a negative effect on dividend payout policy. It is also noticed that firms with diverse boards are more likely to pay dividends and tend to pay larger dividends than those with non-diverse boards. Our results suggest that board diversity has a significant impact on dividend payout policy. Impact of board diversity on dividend payout policy is particularly conspicuous for firms with potentially greater agency problems. Our findings are consistent with the argument that corporate board traits enhancement positively affect the dividend payout policy which is beneficial for shareholders. This study offers useful insights into the current global debate on board traits and its implications for firms. The dividend payout policy signals good news to investors. Corporate board traits and firm's financial decision are the factors that disrupt the dividend decision.

  • There is a growing awareness about the role of the board of directors in decision making, which is crucial to vitalize board activities in Korean firms. Given the academic and social needs, the current study is designed to identify the relationship between board independence and the board involvement of directors, highlighting the important aspects of information provision from diverse channels and information sharing among external directors. In this study, I include not only traditional variables to address the structural independence of the board but also the information provision and information sharing variables to explain how external directors, on average, are involved in board decisions. The research results from 136 Korean business samples show positive relationships between board independence and board involvement, but the influence of information provision and sharing proves to be significant in increasing the level of the board involvement of external directors. These findings suggest that active communication and information sharing among external directors, as well as an independent structural design for the board of directors, are important factors to improve the level of board involvement. Based on these results, the current paper provides theoretical and practical implications for corporate governance and knowledge management. Future research directions and limitations are also discussed.

  • The top-to-bottom compression strength of corrugated board box is the most important mode of loading during it's no, and it depends largely on the edgewise compression strength of the corrugated board in the cross-machine direction and to a considerable extent on the flexural stiffness in both principal directions (CD; cross-machine direction, MD; machine direction) of the corrugated board. Corrugated board is a sandwich structure with an orthotropic property. The purpose of this study was to elucidate the principal design parameters for board combination of corrugated board from the viewpoint of bending strength through the finite element analysis [FEA] fur the various corrugated board. In general, the flexural stiffness [FS] in the MD was 2-3 times larger than that in the CD, and the effect of liner for the FS of corrugated board was much bigger than that of corrugating medium. The flexural stiffness index [FSI] was high when the stiffness of liner was in the order of inner, outer, and middle liner in double-wall corrugated board [DW], and the effect of the stiffness arrangement or itself reinforcement of corrugating medium on the FSI was not high. In single-wall corrugated board [SW] with DW. the variation of FSI with itself stiffness reinforcement of liner was much bigger than that with stiffness arrangement of liner. The highest FSI was at the ratio of about 2:1:2 for basis weight distribution of outer, middle, and inner liner if the stiffness of liner and total basis weight of corrugated board were equal in DW Secondarily. basis weight was in the order of inner, outer, and middle liner. However, the variation of FSI with basis weight distribution between liner and corrugating medium was much bigger than that with itself basis weight distribution ratio of liner and corrugating medium respectively in both DW and SW. md the FSI was high as more total basis weight was divided into liner. These phenomena fur board combination of corrugated board based on the FEA were well verified by experimental investigation.

  • In this paper, I purpose one of the development methods for portable Automatic field Test Equipment(ATE) with VME form factor. Almost portable ATE have not used to standards form factor and they are connected by mechanical non-rigid general connectors and wire harnesses among the components. Furthermore, it is hard to reuse developed board. So, it decreases to reusability of developed board and it is hard to maintenance of ATE. Even those things have weakness for vibration and drop test especially in portable ATE. The XK9A1 ATE using VME form factor has environmental reliability through vibration, drop, temperature test. It consists of 5 developed board called the control board, the wire & wireless communication board, the power supply board, the load board and the mother board. It is connected by two wire harnesses between mother board and extern circular connectors. The control board send the data and address to other board though each 16-bit data and 20-bit address line. You can develop the function board what you want to using those data & address line when it comes to needing other function board.

  • Purpose - We examine empirically the relationship between the board of directors and the corporate performance using board characteristics related variables. Design/methodology/approach - We empirically test the hypotheses using fixed effects models (FEM), using data of 3,703 listed non-financial companies in China from 2010 to 2019. Findings - First, the ownership of board of directors is positively related to ROA. Second, the size of the board of directors is positively related to ROA. Third, there is no evidence that interaction between characteristic variables related to the board of directors affect the corporate performance. Research implications or Originality - These results show that as the board of directors has larger ownership, the degree of identity of interest between stock holders and the board becomes bigger to reduce agency cost, then it lets the board make decisions to improve the corporate performance. In addition, as the board of directors becomes bigger, the board has strong independence to play the role of monitoring and advising, then it leads to improvement of corporate performance.

  • This study is to review "on board notation" on a bill of lading under letter of credit transactions. A bill of lading is a type of document that is used to acknowledge the receipt of a shipment of goods. However, UCP 600Article 20 (a)(ii) requires the bill of lading to indicate that the goods have been shipped on board a named vessel at the port of loading stated in the credit by pre-printed wording, or an on board notation indicating the date on which the goods have been shipped on board. The shipped on board statement should relate to loading on board the named vessel at the port of loading stated in the credit. But it doesn't seem that the on board notation clause in the UCP 600 reflect current shipping practice fully because of the various kinds of on board notation and the confusion surrounding their use. There is a need to understand accurately the meanings and requirements of "on board notation" under UCP 600 and the related regulations. So, This paper will be studied the requirements and indication method of "on board notation" on the bill of lading and presented the practical implications under the bill of lading transactions. This study was based on documentary research including preceding research.
