Reversible Data Hiding Scheme for VQ Indices Based on Absolute Difference Trees

( Chin-chen Chang ),( Thai-son Nguyen ),( Chia-chen Lin ) 한국인터넷정보학회 2014 KSII Transactions on Internet and Information Syst Vol.8 No.7

Reversible data hiding is a technique for recovering original images without any distortion after secret data are extracted from the image. The technique continues to attract attention from many researchers. In this paper, we introduce a new reversible data hiding scheme based on the adjacent index differences of vector quantization (VQ) indices. The proposed scheme exploits the differences between two adjacent indices to embed secret data. Experimental results show that our scheme can achieve a lower compression rate than an earlier scheme by Yang and Lin. Our scheme`s average compression rate, 0.44 bpp, outperforms that of Yang and Lin`s scheme, which averages 0.53 bpp. Moreover, the embedding capacity of our scheme can rise to 1.45 bpi, which also is superior to that of Chang et al.`s scheme [35] (1.00 bpi)Yang and Lin`s scheme [27] (0.91 bpi) as well as Chang et al.`s scheme [26] (0.74 bpi).

Online Experts Screening the Worst Slicing Machine to Control Wafer Yield via the Analytic Hierarchy Process

Lin, Chin-Tsai,Chang, Che-Wei,Wu, Cheng-Ru,Chen, Huang-Chu The Korean Society for Quality Management 2006 The Asian Journal on Quality Vol.7 No.2

This study describes a novel algorithm for optimizing the quality yield of silicon wafer slicing. 12 inch wafer slicing is the most difficult in terms of semiconductor manufacturing yield. As silicon wafer slicing directly impacts production costs, semiconductor manufacturers are especially concerned with increasing and maintaining the yield, as well as identifying why yields decline. The criteria for establishing the proposed algorithm are derived from a literature review and interviews with a group of experts in semiconductor manufacturing. The modified Delphi method is then adopted to analyze those results. The proposed algorithm also incorporates the analytic hierarchy process (AHP) to determine the weights of evaluation. Additionally, the proposed algorithm can select the evaluation outcomes to identify the worst machine of precision. Finally, results of the exponential weighted moving average (EWMA) control chart demonstrate the feasibility of the proposed AHP-based algorithm in effectively selecting the evaluation outcomes and evaluating the precision of the worst performing machines. So, through collect data (the quality and quantity) to judge the result by AHP, it is the key to help the engineer can find out the manufacturing process yield quickly effectively.

( Chin Min Lin ),( Chi Ta Wu ) 전북대학교 인문학연구소 2012 건지인문학 Vol.8 No.-

The purpose of this research is to construct an inventory to explore Taiwanese students` multiple intelligences. Four hundred and nineteen subjects participated in this study. The validity of the inventory was examined by exploratory factor analysis and the internal consistency was examined by reliability test. A set of criteria were used to extract the preliminary 64-item inventory to derive the final 42-item inventory. These criteria included four parts: Eigen values were greater than 1, factor loadings were greater than .3; item-total correlations were greater than .5, and Cronbach`s α values were greater than .6. This proposed inventory can be used to assess students` multiple intelligences more efficiently and effectively teachers then can plan and arrange their instructions accordingly.

Sequence-dependent folding landscapes of adenine riboswitch aptamers

Lin, Jong-Chin,Hyeon, Changbong,Thirumalai, D. The Royal Society of Chemistry 2014 Physical chemistry chemical physics Vol.16 No.14

<P>Expression of a large fraction of genes in bacteria is controlled by riboswitches, which are found in the untranslated region of mRNA. Structurally riboswitches have a conserved aptamer domain to which a metabolite binds, resulting in a conformational change in the downstream expression platform. Prediction of the functions of riboswitches requires a quantitative description of the folding landscape so that the barriers and time scales for the conformational change in the switching region in the aptamer can be estimated. Using a combination of all atom molecular dynamics (MD) and coarse-grained model simulations we studied the response of adenine (A) binding <I>add</I> and <I>pbuE</I> A-riboswitches to mechanical force. The two riboswitches contain a structurally similar three-way junction formed by three paired helices, P1, P2, and P3, but carry out different functions. Using pulling simulations, with structures generated in MD simulations, we show that after P1 rips the dominant unfolding pathway in the <I>add</I> A-riboswitch is the rupture of P2 followed by unraveling of P3. In the <I>pbuE</I> A-riboswitch, after P1 unfolds P3 ruptures ahead of P2. The order of unfolding of the helices, which is in accord with single molecule pulling experiments, is determined by the relative stabilities of the individual helices. Our results show that the stability of isolated helices determines the order of assembly and response to force in these non-coding regions. We use the simulated free energy profile for the <I>pbuE</I> A-riboswitch to estimate the time scale for allosteric switching, which shows that this riboswitch is under kinetic control lending additional support to the conclusion based on single molecule pulling experiments. A consequence of the stability hypothesis is that a single point mutation (U28C) in the P2 helix of the <I>add</I> A-riboswitch, which increases the stability of P2, would make the folding landscapes of the two riboswitches similar. This prediction can be tested in single molecule pulling experiments.</P> <P>Graphic Abstract</P><P>Multi-scale simulations show that a point mutation eliminates the differences in the folding landscapes of <I>pbuE</I> and <I>add</I> A-riboswitches. <IMG SRC='http://pubs.rsc.org/services/images/RSCpubs.ePlatform.Service.FreeContent.ImageService.svc/ImageService/image/GA?id=c3cp53932f'> </P>

Unveiling creative teaching in English instruction

( Chin Min Lin ),( Chi Ta Wu ),( Min Tseng ),( Pei Lu Ma ),( Pei Fang Chang ) 전북대학교 인문학연구소 2013 건지인문학 Vol.10 No.-

This research aims to develop a scale to explore student`s atti-tude toward creative English teaching in Taiwan. Three hundred and nineteen subjects participated in this study. Exploratory factor analy-sis was employed to test the internal consistency of scale and reli-ability test was conducted to measure the internal consistency of the items. The preliminary 32-item scale was scrutinized by a specific set of criteria to develop the final version of the scale. Four items were removed from the scale because they did not meet the requirements. The final scale consisting of twenty-eight items were examined by the same procedure and five factors were extracted from this scale. All of the items in the final scale met the following criteria: Eigen values were larger than 1, factor loadings were larger than.3; item-total cor-relations were larger than.5, and Cronbach`s a value was larger than .6, Teachers and researchers can employ this scale to uncover stu-dents` attitude toward creative English teaching, and modify their teaching methods accordingly.

Lin, Mei-Hsiang,Huang, Sheu-Jen,Shih, Whei-Mei Jean,Wang, Pao-Yu,Lin, Li-Hui,Hsu, Hsiu-Chin Asian Pacific Journal of Cancer Prevention 2013 Asian Pacific journal of cancer prevention Vol.14 No.11

Background and Purpose: Indigenous people who leave their hometowns and move to the city to earn a living became urban aboriginals. During the process of adapting to urban living situations, they may use various coping strategies such as smoking to overcome their stress. Therefore, it is crucial to provide health education including smoking prevention, increasing knowledge regarding of tobacco hazard, self-efficacy of anti-smoking, and adjusting smoking behavior so as to empower their anti-smoking motivation to prevent lung cancer. The purpose of this study was to explore the effectiveness of an anti-smoking program on urban aboriginals in Taiwan. Methods: A quasi-experimental study design with purposeful sampling was employed. A total of 125 aboriginal subjects were recruited from two local churches at Shu Lin area in northern Taiwan. Subjects were divided into an experimental group (n =64 ) and a control group (n = 61). Both took pre-tests in order to set baseline values, and only the experimental group participated for 3-weeks in the anti-smoking program classes. Both groups took post-tests immediately after the intervention in order to evaluate the immediate effects of the teaching program, and a follow-up test was conducted four weeks after the intervention. Data were analyzed using descriptive statistics, one-way ANCOVA, and repeat measure ANCOVA. Results: After controlling for confounding variables, the results showed that there were statistically significant differences in the self-efficacy of anti-smoking and smoking behavior between experimental and control groups in the immediately post-test and the follow-up test (p < 0.05). However, there was no significant differences in the recognition of hazards of smoking at eiter time point. Conclusions and Implications for Practice: The findings of this study revealed that the anti-smoking program effectively improved self-efficacy of anti-smoking, and decreased the smoking behavior in urban aboriginals. They provide useful information as a reference regarding of aboriginal health promotion to health providers. It is imperative that anti-smoking be reinforced for those regular smokers to prevent induction of lung cancer.

Developing a Data Model of Product Manufacturing Flow for an IC Packaging WIP System

Lin, Long-Chin,Chen, Wen-Chin,Sun, Chin-Huang,Tsai, Chih-Hung The Korean Society for Quality Management 2005 The Asian Journal on Quality Vol.6 No.3

The IC packaging industry heavily relies on shop floor information, necessitating the development of a model to flexibly define shop floor information and timely handle manufacturing data. This study presents a novel data model of product manufacturing flow to define shop floor information to effectively respond to accelerated developments in IC package industry. The proposed data model consists of four modules: operation template setup, general process setup, enhanced bill of manufacture (EBOMfr) setup, and work-order process setup. The data model can flexibly define the required shop floor information and decision rules for shop floor product manufacturing flow, allowing one to easily adopt changes of the product and on the shop floor. However, to handle floor dynamics of the IC packaging industry, this work also proposes a WIP (i.e. work-in-process) system for monitoring and controlling the product manufacturing flow on the shop floor. The WIP system integrates the data model with a WIP execution module. Furthermore, an illustrative example, the MIRL WIP System, developed by Mechanical Industrial Research Laboratories of Industrial Technology Research Institute, demonstrates the effectiveness of the proposed model.
