KOREA OUTBOUND TOURISM TO SEVEN COUNTRIES: VAR MODEL AND GRANGER CAUSALITY TEST

This paper investigates the causal relationship among Korean outbound tourism demand for seven countries such as United States, China, Hong Kong, Japan, Philippines, Singapore, and Thailand. Since there are no long-run relationships among Korean outbound tourism demand for those international destinations the vector autoregressive (VAR) model is used for testing such causality. From the causality results, we found United States is leading country for Korean outbound tourism demand. When Korean tourism demands for United States increase, those for the other countries get a raise. Also, tourism demand for Thailand is influenced by tourism demands for three countries such as Hong Kong, Singapore and United States. Our results imply that government and managerial implications are recognized based on the empirical findings

(E)-2,2′-[3-(2-Nitro­phen­yl)prop-2-ene-1,1-di­yl]bis­(3-hy­droxy­cyclo­hex-2-en-1-one)

In the title compound, C21H21NO6, each of the cyclo­hexenone rings adopts a half-chair conformation. Each of the pairs of hy­droxy and carbonyl O atoms are oriented to allow for the formation of intra­molecular O—H⋯O hydrogen bonds, which are typical of xanthene derivatives

Interrelationships Among Korean Outbound Tourism Demand:Granger Causality Analysis

This study investigated Korean outbound tourism demand and its determinants using the Granger causality (GC) analysis. In contrast to previous studies, which dealt only with internal factors, such as exchange rate and income, this study examined the effects of interactions among countries and, therefore, more complete and relevant results were found. Korean outbound tourism to the USA is causally related to Korean outbound tourism to the other six countries in this present study. These results can be applicable for the purpose of tourism marketing and strategies for industries and governments to allocate tourism resources more efficiently.This paper is forthcoming in Tourism Economics

Quantile Elasticity of International Tourism Demand for South Korea using Quantile Autoregressive Distributed Lag Model

This paper investigates international inbound tourism demand for South Korea and its determinants using quantile autoregressive model. In contrast to previous studies which dealt with only conditional mean, we examine effects of covariates at various conditional quantile levels; and therefore, more complete and interesting results are found. For inbound tourism demand, U.S. and Japanese tourism  demand are considered. For U.S. tourism demand, costs of living in Korea and competing destinations have moderate significant negative effects only at very high and low quantiles, while income does not have any significant effect to tourism demand. On the other hand, for Japanese tourism demand, income has significantly positive effects at lower quantiles, and living costs in Korea and competing destinations have significant negative effects at higher quantiles. These results address the heterogeneity in the tourism demand analysis.This paper has been accepted for publication to Tourism Economics

Does the strengthening of IPRs widen the growth gap?

This article builds a model of cumulative growth in order to analyze the relationship between intellectual property rights (IPRs) and economic growth in 38 countries from 1980 to 2005. The analysis focuses on the impacts of IPRs on the growth gap between countries using a catch-up model and USPTO database. The empirical results show that the strengthening of IPRs has a positive impact on innovation in developed and developing countries in Asia, while we fail to find evidence in Latin America. Secondly, similar to assertions made by De Long and Summers (1991) and Dowrick and Nguyen (1989), investment in fixed capital plays a critical role in growth gap dynamics. What needs to be emphasized here is the cumulative causal relationship between investment and growth: investment in fixed capital improves productivity and encourages economic growth thereby triggering even more investment. This paper confirms that the strengthening of IPRs and investment in fixed capital contribute to the widening of the economic development gap for the 1980–2005 period

(E)-2,2′-[3-(2-Nitro­phen­yl)prop-2-ene-1,1-di­yl]bis­(3-hy­droxy-5,5-dimethyl­cyclo­hex-2-en-1-one)

In the title compound, C25H29NO6, each of the cyclo­hexenone rings adopts a half-chair conformation. Each of the pairs of hy­droxy and carbonyl O atoms are oriented to allow for the formation of intra­molecular O—H⋯O hydrogen bonds, which are typical of xanthene derivatives. The nitro group is rotationally disordered over two orientations in a 0.544 (6):0.456 (6) ratio. In the crystal, weak inter­molecualr C—H⋯O hydrogen bonds link mol­ecules into layers parallel to the ab plane

Coal Pulverizer Prognostics Data Challenge in PHMAP 2017 and Suggestions for Future Studies

Pulverizers in a power plant are used to grind coal into the form of a fine powder for combustion in a power plant. To secure reliable operation, redundant pulverizers should be installed in power plants and monitored. Pulverizers can be operated and maintained in a cost-effective manner by correctly estimating the current health condition and remaining useful life of the pulverizer’s gearbox system. To this end, the Data Challenge Committee of the PHM Asian Pacific 2017 (PHMAP 2017) conference organized an open competition on the topic of coal pulverizer health estimation based on a real working power station. This paper presents the original problem and given facts, as well as the list of winners of the Data Challenge Competition. We anticipate that this paper can be used as a reference in the development of a prognostic method that can accurately predict the health conditions of coal pulverizers
