Energy efficiency of resource-constrained wireless sensor networks is critical in applications such as real-time monitoring/surveillance. To improve the energy efficiency and reduce the energy consumption, the time series data can be compressed before transmission. However, most of the compression algorithms for time series data were developed only for single variate scenarios, while in practice there are often multiple sensor nodes in one application and the collected data is actually multivariate time series. In this paper, we propose to compress the time series data by the Lasso (least absolute shrinkage and selection operator) approximation. We show that, our approach can be naturally extended for compressing the multivariate time series data. Our extension is novel since it constructs an optimal projection of the original multivariates where the best energy efficiency can be realized. The two algorithms are named by ULasso (Univariate Lasso) and MLasso (Multivariate Lasso), for which we also provide practical guidance for parameter selection. Finally, empirically evaluation is implemented with several publicly available real-world data sets from different application domains. We quantify the algorithm performance by measuring the approximation error, compression ratio, and computation complexity. The results show that ULasso and MLasso are superior to or at least equivalent to compression performance of LTC and PLAMlis. Particularly, MLasso can significantly reduce the smooth multivariate time series data, without breaking the major trends and important changes of the sensor network system.

Cohesive Devices and Writing Quality : Singapore Learner Corpus Research

Yin Ling Cheung,Hari Jang 한국코퍼스언어학회 2019 Corpus Linguistics Research Vol.5 No.-

Little published research studies examined the relationship between cohesion and writing quality of L2 children’s narrative texts using scientific tools such as Automatic Analysis of Text Cohesion (TAACO) and Coh-Metrix. To fill the research gap, this study investigates the development of cohesive devices and writing quality of 59 ESL grade four students over one semester using TAACO and Coh-Metrix. The corpus for the current study contained 177 narrative texts. Results show that L2 grade four children’s use of cohesive devices and the quality of writing has improved over one semester. Low proficiency group of students tends to use more cohesive devices than high proficiency group. Multi-dimensional assessment of writing quality shows that referential cohesive devices would be positive predictors of complexity by length and subordination. The study has contributed new knowledge in the field of second language writing in terms of research, theory, and pedagogy.

Polyploidy breeding of cassava has been used to improve cassava traits over the past years. We previously reported in vitro induction of tetraploids in the cassava variety “Xinxuan 048” using colchicine. Significant differences in morphology and anatomy were found between the diploid and tetraploid plants. However, very little is known about the transcriptome difference between them. In this study, morphological and physiological characteristics including leaf thickness, plant height, internode length, chlorophyll content, and photosynthetic capacity were measured. Further, we investigated and validated the difference in gene expression patterns between cassava “Xinxuan 048” tetraploid genotype and its diploid plants using RNA sequencing (RNAseq) and quantitative reverse transcription-polymerase chain reaction (qRT-PCR). Significant differences in morphology and physiology were observed during tetraploidization. A comparison revealed that tetraploidy induced very limited changes in the leaf transcriptomes of cassava “Xinxuan 048” diploid and autotetraploid plants. However, the differentially expressed genes (DEGs) between 2× and 4× plants, especially those upregulated in 4× plants, were strongly associated with hormonal and stress responses. Large changes in morphology and physiology between the diploid cassava “Xinxuan 048” and its autotetraploid were not associated with large changes in their leaf transcriptomes. Moreover, the differently expressed genes related to the regulation of gibberellin and brassinosteroids potentially explained why the plant height and internode length of 4× plants became shorter. Collectively, our results suggest that 4× cassava is potentially valuable for breeding strains with improved stress resistance.

Economic Convregence in the European Union

Yin, Ling,Zestos, George K.,Michelis, Leo 세종대학교 국제경제연구소 2003 Journal of Economic Integration Vol.18 No.1

Starting with the Treaty of Rome (1957), the European Union adopted common policies to promote "harmonious economic development and balanced expansion. " The paper investigates how wuccessful such policies were, by examin-ing whether there was economic convergence of the real per capita GDP in the EU. Two measures of convergence are employed. The first is σ, which is based on the cross standard deviation of the real per capitea GDPs of the EU countries; the second is β convergence based on the neoclassical growth model. Both σandβwere estimated using EU data for the period 1960-1995, The empirical findings support the hypithesis of economic convergence within the EU except ofr the 1980-85 sub-period where weak divergence was indicated.

Is “Globalization” the Main Cause of Wage Inequality?

Xiu ling Yin 한국유통과학회 2017 한국유통과학회 학술대회 논문집 Vol.2017 No.-

Trump, the new president of the United States, won the election victory for the reason of meeting the needs of the poor against globalization, which shows that anti-globalization is very popular in the United States. Is Globalization the main cause of rising wage inequality ?There are many theoretical and empirical literature on the relationship between globalization and wage inequality. This paper discusses the development of the theory in the past ten years, mainly discussing the trade model based on matching. Different scholars assume different scenarios, modify the models and get different conclusions. Matching can take a variety of forms. Workers can be matched with firms, with sectors, with managers, or with capital equipment, and the consequences of trade for wages depend on these particulars.

Does the Success of a School-based HPV Vaccine Programme Depend on Teachers' Knowledge and Religion? - a Survey in a Multicultural Society

Woo, Yin Ling,Razali, Sharina Mohd,Chong, Kuoh Ren,Omar, Siti Zawiah Asian Pacific Journal of Cancer Prevention 2012 Asian Pacific journal of cancer prevention Vol.13 No.9

Organized introduction of prophylactic human papillomavirus (HPV) vaccination can reduce the burden of cervical cancer in developing countries. One of the most effective ways is through a national school-based program. Information on teachers is therefore important since this group may have a disproportionate influence in the success of any implementation. Objective: To assess teachers' knowledge and perception of HPV, cervical cancer and HPV vaccine prior to commencing a school-based HPV vaccination program in a multiethnic, predominantly Muslim country. Factors associated with acceptability of the vaccine were identified. Method: A bilingual questionnaire was applied to 1,500 secondary school teachers from 20 urban schools in Malaysia. Data collected were analyzed using SPSS version 17. Results: 1,166 questionnaires were returned. From this group, 46.1% had never heard of HPV while 50.9% had never had a pap smear. However, 73.8% have heard of the HPV vaccine with 75% agreeing to have it. 96% considered themselves religious with 79.8% agreeing to have the vaccine. Conclusions: A national school-based HPV immunization program can be implemented effectively in a multiethnic, cultural and religious country despite limited knowledge of HPV-related pathology among teachers. In addition, the perception that religion has a negative influence on such a program is unwarranted.

The Comparison of Trade Patterns between China and Korea : Competition and Interdependency

Xiu Ling Yin 한국유통과학회 2013 KODISA ICBE (International Conference on Business Vol.2013 No.-

In the past 20 years, both China and Korea has developed greatly in international trade. In some aspects, China has surpassed Korea, now the two countries are the most important trade partners with each other. At the same time, there arise som intense competitions in some fields. Through comparison, we know that China moves up the value chain in terms of gross trade production, but the change in value added trade is much more mixed. Korea is moving up the value chain much better than China. The big changes are a massive loss of competitiveness in primary goods and significant increases in competitiveness in transport equipment and machinery nec(not else classified). Measured by the switch from foreign to domestic sources for intermediates, The latter two sectors are typically considered high-tech so the substitution of Korean intermediates for imported intermediates suggests a move up the value chain in these sectors.

When Failed Motherhood Threatens Womanhood

Elaine Yin-Ling Tsui,Jo Oi-Yue Cheng 숙명여자대학교 아시아여성연구원 2018 Asian Women Vol.34 No.2

Historically, motherhood has long been the defining aspect of womanhood. Chinese traditional culture emphasized that continuation of the bloodline is the filial responsibility of sons and daughters-in-law. Thus, infertility is often socially stigmatized as the loss of ability of a woman as a whole. Assisted reproductive technology through the use of donated gametes provides an alternative option for women to reconfigure womanhood through the process of childbearing. In 2014, in-depth semi-structured interviews were conducted with eight women who have experienced donor-assisted conception (DAC) and successfully given birth to a child. Through interpretative phenomenological analysis, a unique framework of how DAC acculturates and protects compromised womanhood among Chinese females emerged. Findings presented in this paper shed light on how infertility affects womanhood, and the extent to which DAC affects women’s social and self-identities.
