  • The global rise of greenhouse gas(GHG) emissions and its potentially devastating consequences require a comprehensive regulatory framework for reducing emissions, including those from the transport sector. alternative fuels and technologies have been promoted as a means for reducing the carbon intensity of the transport sector. Renewable fuel policies were historically motivated by energy security concerns, and to promoted agricultural industries. In the last decade, biofuels have also been discussed as low or net-zero carbon soures of energy for transportation. Hence, the development of biofuels has been supported by a range of policy instruments, including volumetric targets or blending mandates, tax incentives or penalties, preferential government purchasing, government funded research, development in world-wide. As one of the most powerfuel instruments, renewable fuel mandates require fuel producers to produce a pre-defined amount(or share) of biofuels and blend them with petroleum fuel. In this study, we reviewed Renewable Fuel Standard(RFS, USA), Renewable Transport Fules Obligation (RTFO, UK) as a renewable fuel mandate policy to reduce GHG. This includes not only mandate system for blending of biofuels in transport fuels, but also sustainability to use biofuels in this system.

  • The purpose of this study is to develop the measuring instruments for evaluation criteria for Malcolm Baldrige National Quality Award(MBNQA), suitable for ICT Industries, and to analyze the cause-effect relationship between those criteria through aforementioned instruments. MBNQA is formed with seven categories: Leadership, Strategic planning, Focus on patients, other customers and markets, Measurement, analysis and knowledge management, Human resource focus, Process management and Results. As excluding the Human Resource Focus category, this study empirically examined the cause-effect relationship among six categories. In order to empirically examine the research model, this study calculated Cronbach's alpha and reliability index, thus examined the reliability and executed Exploratory Factor Analysis. Furthermore, Average Variance Extracted(AVE) is used to verify the discriminant validity. Lastly, the hypothesis testing was made complete through significance test on the paths between variables. The result of this study shows that both leadership and social responsibility have direct cause-effect relationship with Measurement, analysis and knowledge management, Human resource focus, Process management and also that this relationship has direct impact on Human resource focus, Measurement, analysis and knowledge management as well, consequently exerting influence on the result through Process management, Finance and Market data.

  • The Dutch construction industry has introduced a compulsory preemployment medical examination (PE-ME). Best-evidence contents related to specific job demands are, however, lacking and need to be gathered. After the identification of job demands and health problems in the construction industry (systematic literature search and expert meeting), specific job demands and related requirements were defined and instruments proposed. Finally, a work ability assessment was linked to the instruments' outcomes, resulting in the modular character of the developed PE-ME. Twenty-two specific job demands for all Dutch construction jobs were identified, including kneeling/squatting, working under time pressure, and exposure to hazardous substances. The next step was proposing self-report questions, screening questionnaires, clinical tests, and/or performance-based tests, leading to a work ability judgment. "Lifting/carrying" is described as an example. The new modular PE-ME enables a job-specific assessment of work ability to be made for more than 100 jobs in the Dutch construction industry.

  • Faith-based investment instruments, such as sharia-based stocks, have developed rapidly in recent years. When investing in these instruments, investors tend to emphasize materialistic returns as measured with monetary returns and metaphysical returns, such as blessings from God (Allah) because of their observance of Islamic teachings. In this respect, it is important to investigate the role of individuals' religiosity in investment decision making in Sharia-based financial products. An equally crucial research question is whether individuals' religiosity levels affect expected material returns as measured by the tolerable negative returns of sharia-based stocks. This study relies on a survey method that involves university students in Java island who actively invest through the Investment Gallery of their faculties/ universities as the sample. Data is then analysed with the multinomial regression analysis technique. The results show that individuals who are more observant of their religious teachings are more likely to fully invest their funds in Sharia-based stocks and exhibit greater tolerance towards the negative returns of Sharia-based stocks. The findings indicate that Muslim investors who are more observant of Islamic teachings emphasize metaphysical returns from their investment decisions.

  • This study was carried out to estimate the stand volume for Japanese larch(Larix leptolepis) by Strand sampling method. The data collected for this study were based on the 380 sample plots from the field survey, which were distributed in the major part of Korea(Kyeongi, Kangweon, Chungbuk, Chungnam, Chunbuk and Kyeongbuki), and the plotless sampling instrument such as dendrometer, spiegel relascope and tele-relascope were used. The procedure for this study is summarized briefly as follows : 1. There were not only significant differences between volume estimation by Strand sampling method and that by plot survey method, and the relationship was y=bx, where b approached nearly 1. Therefore, the stand volume of Japanese larch could by estimated by Strand sampling method. 2. The value measured by three different plotless sampling instruments did not showed any significant differences between instruments and observers, density and instruments, and ground slope and instruments. 3. With the stand volume, basal area height showed the highest correlation and stand form height, average height, basal area per ha correlated with the volume in thier orders. 4. The best fitted equation of stand volume estimation with basal area height by relascope was as follow. log V=-0.0375+0.8910 log GH-1.5946 1/GH Stand volume table also was obtained using the above estimeated equation. 5. The relationship between estimated value and actual value was Y=bx, where b was nearly 1. The correlation coefficient was very high and the percentage of estimated error was 4.5%.

  • In this study, several standard fatty acids were analyzed by three analysis instruments. And also, for the two kinds of soybean oils, fatty acids compositions were determined by three instruments. The results were obtained as follows: 1. In the case of Gas Chromatography (GC), standard fatty acids (Myristic, Stearic, Linoleic, Linolenic, Arachidonic acid) were determined with high reproducibility, but oleic acid/elaidic acid were not seperated. By Capillary Gas Chromatography (CGC), most of standard fatty acids were determined with very high reproducibility than saturated fatty acids, and palmitic acid/oleic acid were not seperated. 2. In the analytical ability of cis-trans fatty acids isomer (oleic acid/elaidic acid), CGC was shown better analytical ability of geometrical isomer than HPLC. Oleic acid/elaidic acid were not seperated by packed column (15% DEGS). The rquire time for standard fatty acids analysis was as follows; GC, 7.21 min., CGC, 9.84 min., HPLC, 24.48 min. 3. The major compositions of fatty acids of each soybean oil (CSOY; refined, DSOY; unrefined) by GC and CGC were linoleic acid, oleic acid, palmitic acid, linolenic acid and stearic acid. But in the case of HPLC, palmitic acid/oleic acid were not seperated. Analytical ability of three instruments on fatty acids composition in each soybean oil was same trend as in the standard fatty acids mixture.
