This study serves as basic research for the development of a new wood-based building finishing material that improved the weakness of inorganic materials such as gypsum board and magnesium board widely used as interior finishing materials and brought out the strength of the wood. The results of evaluating the physical and mechanical properties and the environmental effect related to hazardous substance discharge having manufactured a wood-magnesium laminated composite are as follows. The thermal conductivity and thermal resistance of WML board was improved by about 28~109 percent over magnesium board due to the low thermal conductivity of wood. The adhesive strength of WML board showed a similar result to that of plywood as it exceeds 0.7N/㎟, the adhesive standard of wood veneer which is presented by KS F 3101. Bending strength and screw holding strength were more improved by manufacturing WML board than magnesium board. The WML board manufactured in this study satisfied the criteria for emissions of hazardous substances prescribed in the Indoor Air Quality Control Act, and confirmed the possibility of development as a new wood-based composite material that can replace existing inorganic materials.

This study investigates the relationships of energy firm-level characteristics, namely; firm size, firm leverage, and firm performance with board diligence among companies listed in Saudi Stock Exchange (Tadawul) for the periods ranging from 2012 to 2019. The final sample of this study consists of 32 firm-year observations. A quantitative approach was adopted to test 3 specific hypotheses developed for the board diligence model. Using the Pooled OLS regression, this study finds that firm size and firm performance are negatively associated with board diligence. The results of this study indicate an insignificant association of firm leverage with board diligence. Besides, firm performance is related negatively to board diligence. This indicates that the board of companies with poor performance increases the number of its meetings because of the increased pressure on the board to improve its oversight operations and address the severe performance challenges. The increased number of board meetings observe the daily management of the company, increase the chances for discussions concerning the performance challenges, and come up with solutions faster. The directors are also likely to encounter heightened pressure to appear more engaged during a company's financial distress since lenders require a meeting of the board or with the board.

This study was conducted to determine whether there is a significant relationship between board structure and board committee qualities and corporate cash holdings in Pakistan. For this objective, 168 listed enterprises on the PSX for the period 2016 to 2020 were chosen as a sample from a population of 436 non-financial firms. Multiple regression analysis was used in the study to discover a relationship between board structure and board committee features and cash holdings. The study's findings revealed that board size, executive directors, and board independence have no significant impact on the firm's cash holding because they play no important part in the firm's cash holding. Auditors, audit committee size, audit committee meetings, and the compensation committee, on the other hand, have no major impact on the firm's cash holdings because they are not relevant indicators to compare with cash holdings. While board meeting frequency and leadership structure both have a negative influence on cash holding, board meeting frequency increases firm costs, whereas leadership structure causes agency problems. Results were supported by the pecking order theory, cash flow theory, and agency theory.

Carbon board, an electromagnetic shielding new material, is expected to be applied to the art wall by combining draft designs. When environment-friendly architecture materials are used as an interior wall, they are suitable as finishing materials. According to the increasing tendency of the application of carbon board, various styles could be made by decorating the whole or a part of a wall with tiles with module structure or by patterning the wall with panel-type woodcut or pictures or sculpture. And more graphic design based on diverse variation, and reconstruction and combination between other motif is being on the rise as a new expression. In this paper, make it possible to applying in MDF board and carbon board pattern design using the woodcut technique. The structural and physical properties were compared by usability of abrasion, toughness, stability. Samples are analyzed dependent on the hardness and relative density, change of detail pattern design and trimming technique. These results have shown that the possibility of applying of carbon board can be a high rank interior materials, capable of creating value of the living system, connects with MDF board, also can express humanism in a beautiful manner.

This paper aims to understand the points which the Board of Directors of the National Federation of Fisheries Cooperatives System has proposed, and to find some improvement. This Fisheries Cooperatives previously had a single board system operating two small board rooms which became independent within the two sectors of credit and .provision in addition to the existing board of directors. This is a very unique board of directors system which is not found in cooperatives in our country nor in the business world. This change of the board of directors of the Fisheries Cooperatives is ascribed to the reorganization of the system into a completely independent division system, which operates business separately based on each sector as opposed to the previous multiple cooperatives system. However, a plural board of directors system does contribute to the improvement of managerial efficiency by strengthening the self-control of each independent business section, but deepens conflicts between its internal organizations, and brings about a reverse function which might deteriorate both the controlling power of a systematic organization and the coordinating power between sectors. This paper made an analysis of acceptors' attitudes toward the board of directors of the fisheries cooperatives system by regulating all the staff directly related to the operation of the board of directors of the fisheries cooperatives system as a group of acceptors and by selecting one hundred and fifty persons among the staff as a sample. The inquiry into acceptors' attitudes was made using questionaries, and the data for this investigation was processed and analyzed using a statistical method. The contents of this paper are composed of I. an introduction, II. the findings of the questionary investigation, III. the overall opinion for the improvement of the board of directors system, and IV. a summary and conclusion.

Little empirical study has been conducted concerning board function effectiveness and organizational performance in nonprofit nongovernmental human service organizations in Korea. Using the evaluations of 107 board members and 17 executive directors in Korean Community Chest and 16 regional community chests, this study attempted to examine the level of board function effectiveness and its relationship with organizational performance in these community chests. This study used board function scale developed by Holland and Jackson (1998) to measure board function effectiveness in the following 6 dimensions: contextual dimension: educational dimension: interpersonal dimension: analytical dimension: political dimension: and strategic dimension. This study showed that using 4 points scale, mean of overall board function effectiveness evaluated by board members is 2.62 and mean of overall board function effectiveness evaluated by executive directors is 2.73. That is, it showed that means of overall board function effectiveness are located in the middle point between negative evaluation and positive evaluation. On the other hand, using parametric correlation analysis method, it was found that in these community chests the association between board function effectiveness and organizational performance measured by fund-raising growth rate in $1999{\sim}2000\;and\;1998{\sim}2000$ is very weak and statistically nonsignificant. This study also revealed that using nonparametric correlation analysis method, the association between consensus level in evaluation by board members and executive directors about board function effectiveness, and organizational performance is still very weak and statistically nonsignificant. Finally, this study discussed the direction of future research in board function effectiveness and its relationship with organizational performance and the areas of board management that requires substantial efforts for promoting effectiveness of nonprofit human service organizations in Korea.
