  • Soil moisture, through its dominance in the exchange of energy and moisture between the land and atmosphere, plays a crucial role in influencing atmospheric circulation. To identify the crucial role, it is a common agreement that knowledge of land surface processes and development of remote sensing techniques are of great important scientific issues. This research uses TRMM satellite C band (10.65 GHz) data to retrieve soil moisture on the Tibetan Plateau in Mainland China. Two retrieval schemes that are implemented include the t-(J) model and the R model. The latter one is developed based on a land surface process and radiobrightness (R) model for bare soil and vegetated terrain. Compared with the in situ ground measurements, the soil moisture retrieved from the R model and the t-(J) model with vegetation information obviously appear more accurate than that derived from bare soil model. Retrieved soil moisture contents from the two inversion models, R model and t-(J) model, have a similar trend, but the former appears to be superior in terms of correlation coefficient and bias compared with in situ data. In the future, we will apply the R model with the TRMM 10.65 GHz brightness temperature to monitor long-term soil moisture variation over Tibet Plateau.

  • The Jiangyin Bridge is a suspension bridge with a main span of 1385 m over the Yangtze River in Jiangsu Province, China. Being the first bridge with a main span exceeding 1 km in Chinese mainland, it had been instrumented with a structural health monitoring (SHM) system when completed in 1999. After operation for several years, it was found with malfunction in sensors and data acquisition units, and insufficient sensors to provide necessary information for structural health evaluation. This study reports the SHM system upgrade project on the Jiangyin Bridge. Although implementations of SHM system have been reported worldwide, few studies are available on the upgrade of SHM system so far. Recognizing this, the upgrade of original SHM system for the bridge is first discussed in detail. Especially, lessons learned from the original SHM system are applied to the design of upgraded SHM system right away. Then, performance assessment of the bridge, including: (i) characterization of temperature profiles and effects; (ii) recognition of wind characteristics and effects; and (iii) identification of modal properties, is carried out by making use of the long-term monitoring data obtained from the upgraded SHM system. Emphasis is placed on the verification of design assumptions and prediction of bridge behavior or extreme responses. The results may provide the baseline for structural health evaluation.

  • The paper addresses the importance of redesigning strategies for resilient and sustainable regional economic development - by applying strategic approaches to free economic zones for the digital economy. The purpose of the paper is to provide a broad comparative perspective on developed versus developing country efforts to use free economic zone programs to enhance various economic and social objectives. First, the paper introduces the chronicle experiences of free economic zone programs in South Korea and mainland China - developed versus developing economies. The main results of the analysis indicate that (1) achieving the goals and objectives of free economic zones is challenging over time; (2) trying to upgrade the technical component, develop knowledge-based and eco-friendly new industries, or value-added to the economy through free economic zone policies is even challenging; and (3) incentives and other program-specific variables are highly context-specific and not structurally correlated with free economic zone performance. In addition, the paper shows that the initial conception of the role of free economic zones has undergone significant change as individual countries have tried to enhance the contributions and avoid damages from incorporating free economic zones into their development strategy respectively, over time.

  • Mainland China area has been a long-term, major trade rival and partner of Taiwan, accounting for more than 40% of Taiwan's total annual trade exports, and so Sino-US trade friction is expected to have a significant impact on Taiwan's economy in the future. This study focuses on major bad news of Sino-US trade frictions and how it generates short-term shocks for Taiwan's equity market and fear sentiment. It further explores the mutual interpretation relationship between price changes such as VIX, Taiwan's stock market index, and the VIX ETF to identify which factors have information leadership as leading indicators. The study period covers 750 trading days from 2017/1/3 to 2020/1/31. This study finds that, when a policy news is announced, the stock market index falls significantly, the change in the trading price (net value) of the VIX ETF rises significantly, and the overprice rate significantly drops, but VIX does not, showing that fear sentiment exists in the Taiwan's market. The net value of the VIX ETF shows an information advantage as a leading indicator. This study suggests that, when the world's two largest economies clash over trade, the impact on Taiwan's equity market is inevitable, and that short-term fear effects will arise.

  • There are a great number of man-made and natural slopes in many parts of the world including Hong Kong and Mainland China. For example, there are over 40,000 slopes in Hong Kong registered by the Hong Kong Government. Landslides due to slope failures can often cause catastrophes that involve the loss of both lives and important facilities. GPS has been demonstrated to have great potentials for use in monitoring slope stability and landslides. However, the high hardware cost of GPS has limited the wide spread use of GPS for such applications. The multi-antenna GPS technology initiated by the research group and our collaborators has significantly reduced the cost of GPS and provided a solution to a number of associated problems such as data management and power supply. This paper discusses practical applications of multi-antenna GPS technology in slope monitoring, including system design, setting up, data transmission and management, and data quality analysis and control. Some slope monitoring examples are given to illustrate the points discussed.

  • The Korean field mouse, Apodemus peninsulae mitochondrial genome has previously been reported for mice obtained from mainland Korea and China. In this investigation the complete mitochondrial genome sequence for a mouse obtained from Baengnyeong Island (BI) in South Korea was determined using high-throughput whole-genome sequencing for the first time. The circular genome was determined to be 16,268 bp in length. It was found to be composed of a typical complement gene that encodes 13 protein subunits of enzymes involved in oxidative phosphorylation, two ribosomal RNAs, 22 transfer RNAs, and one control region. Phylogenetic analysis involved 13 amino acid sequences and demonstrated that the A. peninsulae genome from BI was more closely grouped with two Korean samples (HQ660074 and JN546584) than the Chinese (KP671850) sample. This study verified the evolutionary status of A. peninsulae inhabiting the BI at the molecular level, and could be a significant supplement to the genetic background.

  • This paper treats with transitional development of medico-hygienical situation in district Yanbian along with the evolution in specific field of medicine. This work is particularly important in shaping TKM identity as TCM embraces Chao medicine asserting it as one included in TCM. This research deals with themes of migration of Chao minorities to this territory and their medico-hygienical situation. Lifted bans on immigration in late Qing dynasty with uncertainty of Korea(Chosun) triggered the immigration to this district. The flow was heavily strengthened under the influence of Westerners and Japanese imperialism into china which consequently provoked the ruin of Qing dynasty, the civil war between republicans and communist and the socio-political changes in Korea. As population growths, the establishment of hospitals and immigration of healthcare professionals were also increased. Though this district is located in Chinese mainland the influence of Japanese was also relevant which lead to medical practice reflecting both sides. Mutual combination and influence of western(contemporary) medicine, TCM and TKM practices made the particularity of Chao medicine.

  • This study aims to investigate the rhythmic patterns in the English speech produced by Chinese learners of English who learn English as a foreign language (EFL learners). Utilizing interval-based rhythm metrics, namely, VarcoC, VarcoV, nPVI-C, nPVI-V, and %V, the study compared the rhythmic differences in English speech between ten native speakers from the United States and forty Chinese EFL learners from mainland China. A sentence elicitation task consisting of thirty picture prompts and corresponding thirty stimuli sentences with at least five vocalic and four consonantal intervals was conducted. Statistical results reveal that both Chinese advanced learners and beginners had significantly lower degree of stress-timed in their English speech, indicating that the acquisition of the L2 speech rhythm was influenced by the learners' L1 rhythmic pattern. In addition, the results also show that the Chinese advanced learners had significantly higher degree of stress-timed in their English speech than beginners and showed no significant difference with native speakers in VarcoC and nPVI-C. These results indicate that the direction of L2 speech rhythm development was from more syllable-timed to more stress-timed.

  • Purpose: This paper aims to investigate how self-regulatory focus (SRF) influences the relationship between perceived brand localness (PBL) and purchase intentions (PI). This research adopted both domestic and foreign-owned brands to examine the moderating effect of self-regulatory orientations and product types respectively to exclude the interference of brand origin. Research design, data, and methodology: This study surveyed Chinese consumers and collected data using social media applications. ANOVA analysis and PROCESS modeling were adopted to complete the empirical analysis. Results: This research demonstrates that brand origin does not inhibit the positive impact of PBL on purchase intentions regardless of whether it originates from mainland China or not. Study 1 proved that the effect of PBL on PI is more convincing among consumers with promotion focus orientations. In study 2, higher purchase intentions were found for hedonic perceived local brands among promotion-focused consumers while significant preferences were found for utilitarian perceived local brands among prevention-focused consumers. Conclusions: This research complements the literature about the potential psychological factors influencing PBL and contributes to marketers in developing effective marketing strategies and appropriate positioning decisions. Overall, this study has important theoretical and managerial contributions to international marketing, particularly in the context of the current recession.
