Purpose: This study aims to analyze the determinants of Green Total Factor Productivity (Green TFP) growth in the agricultural sector in Indonesia from 1980-2018. Research design, data, and methodology: The growth of Green TFP in the agricultural sector is calculated using the Growth Accounting Method. Moreover, this study uses multiple linear regression to analyze the determinants of the growth of Green TFP in the agricultural sector in Indonesia. Results: The survey results show that the average growth of Green TFP in the agricultural sector in Indonesia is still negative, which indicates that the efficiency of production factor or mastery of technology is still low. Inflation and patent applications are variables that significantly affect the growth of Green TFP in the agricultural sector, where the inflation variable has a negative effect. In contrast, the variable growth of patent applications has a positive impact. Conclusions: The government needs to continue to improve efficiency by organizing various programs related to increasing mastery of technology in the agricultural sector. The government also needs to advance research and development by promoting patents to become research incentives and impact the improvement of new technologies, especially those related to the environment. Moreover, economic stability needs to be maintained through inflation control.

As customer needs for eco-friendly transportation services increase, strategies of major global shipping companies are being established to meet them. Even if logistics costs increase, more and more shippers are choosing shipping companies that fulfill their social responsibilities through decarbonization, and against this backdrop, global shipping companies want to strengthen corporate social responsiveness and reduce shipping environmental costs. In the post-corona era after COVID-19, it is necessary to review the latest Green Shipping management strategies of shipping companies emerging as a new normal for the shipping and logistics industries. This study aims to explore trends in the latest Green Shipping management strategies of global shipping companies pursuing environmental load suppression in the shipping and logistics fields. Among the previous studies, some studies analyzed the green shipping policies of major shipping countries, but they did not deal with the latest policies over time, and few previous study has conducted a fact-finding analysis on the latest Green Shipping management strategies of major shipping companies at the corporate level. This study attempted to analyze securities reports by major domestic and international shipping companies and to present the latest Green Shipping management strategies by shipping companies.

The purpose of study was to develop new dental plaque disclosants which could replace erythrosine. Three food coloring agents(Red No.40, Blue No.1, and Mixed Green), erythrosine and fluorescein were tested for their color difference, antibacterial property, and biocompatibility. Color difference of Red No.40 was greater than that of erythrosine as concentration of solution increased. Color differences of Blue No.1 and Mixed Green were smaller than that of red dyes. Erythrosine showed obvious antibacterial property, but food coloring agents showed almost no antibacterial property. The taste and sensation of erythrosine was the worst, and the taste of Red No.40 and the sensation of Mixed Green were the most tolerable. Erythrosine stained dental plaque and oral soft tissue most deeply and long, and Blue No.1 was the next in the depth and longevity of stain.

We achieved a highly efficient green OLED with an efficiency of 30cd/A by using a new electron transport material and optimizing the device structure. The luminous efficiency was 16.8lm/W at $3000cd/m^2$ and the lifetime was over 60,000hr at an initial luminance of $1000cd/m^2$. Furthermore, we obtained a threecomponent RGB white OLED by using the highly efficient green material. This RGB white OLED shows more excellent color reproducibility for full color displays with color filters, compared to a twocomponent white OLED.

The corrosion on steam generator tubes of the secondary side of pressurized water reactor inhibits heat transfer. One of the most efficient techniques improving the heat transfer performance of a nuclear electric generation is a corrosion control. The environmental parameters mostly affecting corrosion are materials and chemical additives. It seems that no further corrosion occurs in steels with Polyacrylic acid polymer dispersant treatment. Polyacrylic acid forms a protective coating with uniform thickness on metal surface. Polyacrylic treatment appears to be the most convenient way to enhance the thermal performance by the thermal conductivity improvement in steam generators.

A Krawtchouk polynomial is introduced as the classical Mac-Williams identity, which can be expressed in weight-enumerator-free form of a linear code and its dual code over a Hamming scheme. In this paper we find a new explicit expression for the $p$-number and the $q$-number, which are more generalized notions of the Krawtchouk polynomial in the P-polynomial schemes by using an extended version of a discrete Green's function. As corollaries, we obtain a new expression of the Krawtchouk polynomial over the Hamming scheme and the Eberlein polynomial over the Johnson scheme. Furthermore, we find another version of the MacWilliams identity over a Hamming scheme.

A new Cu-Hf-Al-Be monolithic bulk amorphous alloy was developed utilizing minimal use of toxic and expensive Be. The developed alloy exhibits a large glass forming ability (GFA) (${\Phi}8$ mm). The possible mechanisms underlying the enhancement of the glass forming ability by this alloy are discussed based on the dimensionless parameter ${\gamma}$. In addition, alloy design strategy for the improvement of GFA is proposed in the viewpoint of heat of mixing (${\Delta}H_{mix}$)difference and atomic packing state.

We developed new green emitting materials based on the spiro moieties. The introduction of a spiro linkage into the structure of DJGH series lead to a reduction in crystallization tendency and an increase in glass transition temperature. they showed much better emitting efficiency and color purity than commercial host material $Alq_3$.

Green Standard for Energy and Environmental Design(G-SEED) has been implemented for the realization of sustainable development and resource-saving and eco-friendly buildings from 2002. Studies about the green buildings are made actively and is being developed through constant revision. However, study results of green building have not been fully reflected in the standard. Therefore, this study analyzes the previous studies about G-SEED for school facilities and check the degree of to reflect the problems and improvements suggested in previous studies. This study will be a reference of future revision Substantial problems and requirements are not reflected in revision standard. Proposed improvement requirements are classed as to improve the items(establish specific standards, supplementation), strengthen standards(designate the prerequisite items), propose a new evaluation method, add new items. delete exist items and adjust the score. Therefore, future revision of G-SEED for school facilities should reflect the results of previous studies.

The Purpose of this study was to investigate the exterior materials of super high-rise housing more than 30 stories which were built in New York City between 1924 and 2004. The result of examining 153 buildings was as follows; Exterior materials of super high-rise housing which were used bricks, of the salt-glazed bricks, terra-cotta and ceramic tiles, jumbo bricks and bricks were preferred among them. The colour of bricks was yellow, yellow ochre, clear brown, brown, dark brown, orange, vermilion and red. Exterior materials of super high-rise hotel and hotel apartment were bricks and ceramic tiles in the early days but stones, curtain wall and glass(green glass, green-tinted glass, brown-tinted glass, black glass) after 1980s. The main colour of buildings extended gray, green, blue-tinted brown-tinted and black.
