With the advent of smart age, the concern on smart work has gradually increased in solving our social problems including low birth, aging, low productivity and green growth with low carbon as well as encouraging the balance between work and life. In addition, the competitiveness among companies and countries to preoccupy the advanced smart work technologies which lead the economic growth in the future have increased more than ever before. So have global standard competitiveness done under the situation of using international standardization as practical strategy for dominating market. It is essential to make standardization strategy and do systematic implementation for core technology which leads global market in order to fit such an environment and introduce smart work as soon as possible. Therefore, this paper suggests standardization items which lead global standard and implementation direction on standardization through analysing the current situation introducing smart work and technology/standardization trend.

The indiscriminate growth in global population poses a threat to the world in handling and disposal of Municipal solid waste. Rapid urban growth increases the production, consumption and generation of Municipal solid waste which leads to a drastic change in the environment. The methane produced from the Municipal Solid waste accounts for up to 11% global anthropogenic emissions, which is a major cause for global warming. This study reports the methane emission estimation using IPCC default, TNO, LandGEM, EPER and close flux chamber from open dump yards at Perungudi and Kodungaiyur in Chennai, India. The result reveals that the methane emission using close flux chamber was in the range of 8.8 Gg/yr-11.3 Gg/yr and 6.1Gg/yr to 9.1 Gg/yr at Kodungaiyur and Perungudi dump yard respectively. The per capita waste generation was estimated based on waste generation and population. The waste generation potential was projected using linear regression model for the period 2017-2050. The trend of CH₄ emission in the actual field measurement were increased every year, similarly the emission trend also increased in IPCC default method (mass balance approach), EPER Germany (zero order decay model) where as TNO and Land GEM (first order decay model) were decreased. The present study reveals that Kodungaiyur dump yard is more vulnerable to methane emission compared to Perungudi dump yard and has more potential in waste to energy conversion mechanisms than compare to Perungudi dump yard.

In this study, international standardization trend of smart mining technology was analyzed focusing on the guidelines developed by GMG (Global Mining Guidelines Group). GMG is a non-profit organization that unites the global mining community. It was established to promote mining safety, innovation and sustainability. Currently, GMG's working group consists of artificial intelligence, asset management, autonomous mining, cybersecurity, data access and usage/interoperability, the electric mine, mineral processing, underground mining, and sustainability. Guideline development projects related to smart mining technology are being conducted in artificial intelligence, autonomous mining, cybersecurity, data access and usage/interoperability, and underground mining. As of April 2022, eight types of smart mining-related guidelines have been published through pre-launch, launch, guideline definition, contents generation, technical editing/layout/final review, and voting process. It is judged that the GMG guidelines can be an important reference for the development of domestic smart mining technology standards.

This paper aims to determine factors causing the stagnation of Korean firms' fixed investment after the global financial crisis, using panel data for the period of 1999-2016. Fixed investment remained sensitive to cash flow and Tobin's q although their effects decreased after the global financial crisis. A decreasing trend of cash flow and an increase in Tobin's q since the early 2000's imply that the worsening cash flow was a major factor behind the sluggish investment after the crisis. Meanwhile, debt-equity ratio remained significant for non-chaebol affiliated firms, reflecting disparity in access to external financing. Volatility of stock returns also became insignificant after the crisis, casting doubt on the argument that uncertainty was a major factor contributing to the decline of fixed investment. Analysis of financial investment confirmed the significant effect of cash flow, larger than that on financial investment than on fixed investment. In particular, debt repayment and other financial investment, except share repurchase, were sensitive to cash flow. However, the substitution of fixed investment by financial investment is a consequence, rather than a cause of declining fixed investment.

The US dollar has kept as a position of key currency in the global economy in the changing international monetary system where the euro was introduced to some states of the EU in 1999. It is an evidence of inertia of the US dollar as a key currency. Our previous study (Ogawa and Muto, 2017b) conducted empirical analysis to investigate effects of several events on inertia of the US dollar. One of our findings was that the introduction of the euro increased utility of euro while utility of US dollar was kept unchanged. This paper examines the effects of the global financial crisis and the euro zone crisis as well as the introduction of the euro on the utility of the Japanese yen. The introduction of the euro significantly decreased the utility of the Japanese yen. It indicates that the introduction of the euro increased the utility of the euro while reducing the utility of the Japanese yen rather than the utility of the US dollar. The utility of the Japanese yen has significantly decreased while the global financial crisis and the euro zone crisis occurred. The Japanese yen has a declining trend in terms of its utility over time in the changing international monetary system.

CTD data taken in the Ulleung Basin between 1996 and 2001 are analyzed to understand the hydrography around Dokdo. Major features occurring in the Ulleung Basin such as the path variability of the East Korean Warm Current (EKWC), the location and size of the Ulleung Warm Eddy (UWE) and the position of the Offshore Branch along the Japanese coast all influence the hydrography around Dokdo. The Dokdo area frequently lies in the eastern part of the meandering EKWC and the UWE that results in a filting of isolines sloping upwards to Dokdo in the Ulleung Interplain Gap (UIG) between Ulleungdo and Dokdo. Subsurface water near Dokdo then becomes colder and less saline than water near Ulleungdo. Two cases that are opposite to this general trend are also identified when the Dokdo area is directly affected by the EKWC and by a small scale eddy ffd by the Offshore Branch. High salinity cores and warm waters are then found near Dokdo with isolines sloping upwards to Ulleungdo. Freshening of the East Sea Intermediate Water was observed in the UIG when neither the EKWC nor the UWE was developed in the Ulleung Basin during June-November 2000.

This research examined a task to foster into the export industry, through analyzing the competitiveness of the ornamental fish industry and identifying the position of Korea's ornamental industry in the world. Ornamental fish in Korea holds the world's leading aquaculture technology, but products are limited to a few species, lacking competitive products. In the case of aquarium supplies, the Korean technology level is receiving relatively positive marks in the global market, but ornamental fish products are lagging behind the global trend. In other words, Korea's ornamental fish industry has the overall technical foundation, but lacks differentiation in the global market. Meanwhile, Korea's market share of world trade market in fishery products is minimal. Growth was also analyzed not high compared to other countries. Various trade competitiveness index results rated very low in competitiveness, but it is hard to compare Korea with other countries which have already built a strong foundation in the ornamental fish industry. Therefore, for the mid to long term Korea should adapt a "Choice and concentration" strategy and focus on the production of ornamental fish and aquarium supplies, which will enable Korea to become differentiated in the global market and capture the world exports.

"The world is flat" as the popular author Thomas L. Friedman declares in his best belling book about the progress of business globalization in the $21^{st}$ century [3]. Construction projects and related businesses have been global since the 1800's, but it has never seen such rapid transformation in both scope and depth as in the past decade. Construction projects today often bring together international design talents, construction management firms, local and international labor forces, and global suppliers. On a visit to Dubai in the United Arab Emirates on the Persian Gulf, a person will experience the complexity of globalization of modern construction projects- with Arab owners, European engineering and design companies, American construction management teams, Korean general contractors, Jordanian subcontractors, and labor forces from Thailand, Indonesia, Turkey, and Sri Lanka. A count of material suppliers reveals over 60 countries involved, covering all continents. Indeed construction projects are getting more and more complex and competitive, as is the project execution. The trend toward globalization poses both challenges and opportunities to construction and engineering companies competing on a global scale. While global competition may be a threat to many companies, there are, however, many opportunities for synergistic collaborations that can create win-win scenarios for construction business, research, and education. This paper presents some of the opportunities between the U.S. and Asia in business integration, research collaboration on technologies, and educational development, which may mutually benefit countries on either side of the Pacific.

This study attempts to analyze the critical issues of globalization and present an alternative framework that places ICT in the function of development in comparative perspective. To adjudicate the controversies concerning the effect of developmental factors, it examines the determinants of global trend that leads to the comprehensive mechanism of ICT and cultural residues. The advent of the global community in cyber space requires a new balancing point by the mode of communication and culture among all societies and operation with decentralized authority. This interdependence, by providing diverse network structures and participating in cyberspace, includes the power shift from the dynamics of international relations with voluntary collaboration and brings some important implications for a global empathetic society.

The aim of this research is to examine the tendency of national tastes reflected in global SPA brands based on the theories of Gans' taste culture and Bourdieu's cultural capital. In this study, the leading global SPA brands such as H&M, ZARA, GAP and UNIQLO can be considered as a representative taste culture as well as an icon of popular culture in the $21^{st}$ century global fashion and also the aesthetic taste of each brand differentiated from their national aesthetic values based on socio-cultural backgrounds. H&M represents fashionableness, practicality and environmental friendliness based on naturalism, democratic humanism, and functional practicality of Sweden. ZARA emerges as the most trend oriented brand as well as customer centered on the basis of cultural diversity, passion and glamorous artistic sensibility of Spain. GAP shows American iconic style, which is the functional sports casual wear, originated from American leisure culture and mass production. Lastly, UNIQLO represents high-tech functionalism and practical simplicity based on Japanese delicate workmanship and simple, concise lifestyle while relatively does not much follow the fashion forward trends. Consequently, the national taste has been proved as a solid foundation to identify each global brand. This should be the key component also applied to Korean global brands for developing their concepts and strategies more successfully based on our own national aesthetic taste.
