This research aims to develop the multiple channel electrochemical DNA chip using microfabrication technology. At first, we fabricated a high integration type DNA chip array by lithography technology. Several probe DNAs consisting of thiol group at their 5-end were immobilized on the sold electrodes. Then target DNAs were hybridized and reacted. Cyclic voltammetry showed a difference between target DNA and control DNA in the anodic peak current values. Therefore, it is able to detect a plural genes electrochemically after immobilization of a plural probe DNA and hybridization of non-labeling target DNA on the electrodes simultaneously. It suggested that this DNA chip could recognize the sequence specific genes.

One serious problem among the troubles to identify objects in an optical microscopic image is contour background due to non-uniform light source and various transparency of samples. To solve this problem, this paper proposed an elimination method of the contour background and compensation technique as follows. First, Otsu's optimal thresholding method extracts pixels representing background. Second, bilinear interpolation finds non-deterministic background pixels among the sampled pixels. Third, the 2D cubic fitting method composes surface function from pivoted background pixels. Fourth, reconstruction procedure makes a contour image from the surface function. Finally, elimination procedure subtracts the approximated background from the original image. To prove the effectiveness of the proposed algorithm, this algorithm is applied to the yeast Zygosaccharomyces rouxii and ammonia-oxidizing bacteria Acinetobacter sp. Labeling by this proposed method can remove some noise and is more exact than labeling by only Otsu's method. Futhermore, we show that it is more effective for the reduction of noise.

After analyzing the actual acquisition status of carbon labeling by year and by product for the past four years, as well as its certification in the construction-related sectors of greenhouse gas emission, this study attempted to present the problems and coping strategies upon issuing the carbon labeling certification in the landscape architecture. During the period of this analysis, the carbon labelings were acquired by 134 enterprises, 267 workplaces, and 735 products, while the percentage of acquisition was highest in the regular non-durable goods(49%), followed by energy-consuming durable goods(26%), regular production goods (19%), regular durable goods(3%), and service(3%). Furthermore, the acquisition certifications in construction sectors, were highest in the various pipes/panel(8 cases), followed by concrete(6 cases), gypsum board(4 cases), and landscape architecture materials(2 cases). The landscape architecture only had two cases in the acquisition certification for the first time in 2012, which accounted for 0.27% of the entire certification products, due to the uncertainty in the process, the lack of professionalism, and the lack of comprehension. However, the study conducted on the coping strategies for carbon labeling in the landscape architecture revealed the following: (1) regular reporting system management through the division of labor in the head office and factories, (2) the building of objective DB through the adoption of data management programs such as SAP, (3) continuous promotion and vitalization of the incentive system, (4) the adoption of mandatory or preferential application system in landscaping projects, management, and bidding, (5) enhancement of elasticity in deliberation of certification by recruiting experts in the landscape architecture sectors, and (6) provision of incentives for the cooperative firms acquiring the certification and support for their participation.

This paper examines the categorical labeling of lexical pitch accent contrasts in North Kyungsang and South Cholla Korean listeners. It focuses specifically on investigating whether the pitch accent perception of adults and children has a dialect-specific effect. To evaluate the development of perceptual identification, slopes, intercepts, and positions at categorical boundaries were computed using a logistic regression function. The results showed that differences in slopes and intercepts were significant between North Kyungsang child and adult listeners, but the same was not the case for the positions at boundaries. As far as South Cholla child and adult listeners were concerned, there was a significant difference in slopes, but not intercepts and positions at boundaries. In the present study, the comparison of intercepts and slopes at the boundaries indicated developmental differences between North Kyungsang adult and child listeners. This improvement in categorical proportion seems to be a result of developmental changes in categorical perception. For South Cholla adult and child listeners, however, perception of the non-native contrast becomes less categorical.

Overnutrition is one of the major causes of non-alcoholic fatty liver disease (NAFLD). NAFLD is characterized by an accumulation of lipids (triglycerides) in hepatocytes and is often accompanied by high plasma levels of free fatty acids (FFA). In this study, we compared the energy metabolism in acute steatotic and non-steatotic primary mouse hepatocytes. Acute steatosis was induced by pre-incubation with high concentrations of oleate and palmitate. Labeling experiments were conducted using [$U-^{13}C_5$,$U-^{15}N_2$] glutamine. Metabolite concentrations and mass isotopomer distributions of intracellular metabolites were measured and applied for metabolic flux estimation using transient $^{13}C$ metabolic flux analysis. FFAs were efficiently taken up and almost completely incorporated into triglycerides (TAGs). In spite of high FFA uptake rates and the high synthesis rate of TAGs, central energy metabolism was not significantly changed in acute steatotic cells. Fatty acid ${\beta}$-oxidation does not significantly contribute to the detoxification of FFAs under the applied conditions.

Purpose - This study aims to explore the influence of combining "non-halal" labels with visual and textual warning labels on cigarette packages to induce the intention to quit smoking and boost the stop-smoking campaign. Research design, data, and methodology - This study examines"non-halal" labeling on cigarette packages using an experimental method. A total of 120 smokers, aged 18-23, were chosen from among Universitas Indonesia students. Data obtained were analyzed using ANOVA and T-Test. Results - The use of a "non-halal" label as a warning on cigarette packages is more effective to influence Muslim smokers to quit smoking. The results also suggest that "non-halal" labels more effectively increase intentions to quit smoking when use din combination with textual-visual labels. Conclusions - The study found that the addition of "non-halal" labels in textual or textual-visual warning labels on cigarette packages would significantly increase the intention of Moslems smokers to quit smoking. These results support previous research findings, that if cigarettes are labeled as "non-halal" (haram) products for Moslem teenagers, it will induce them to quit smoking.

This paper deals with an input device without the touch. The existing touch screens have some problems such as the week durability by frequent contact and the high cost by complex hardware configuration. In this paper, a non-touch input device is proposed to overcome these problems. The proposed method uses a skin color generated by the HCbCr color model and a hand region obtained by the labeling technique. In Addition, the skeleton model is employed to improve the recognition performance of the hand motion. Finally, the experiment results show the applicability of the proposed method.

Recently, a deep learning-based non-profiling side-channel analysis was proposed. The deep learning-based non-profiling analysis is a technique that trains a neural network model for all guessed keys and then finds the correct secret key through the difference in the training metrics. As the performance of non-profiling analysis varies greatly depending on the neural network training model design, a correct model design criterion is required. This paper describes the two types of loss functions and eight labeling methods used in the training model design. It predicts the analysis performance of each labeling method in terms of non-profiling analysis and power consumption model. Considering the characteristics of non-profiling analysis and the HW (Hamming Weight) power consumption model is assumed, we predict that the learning model applying the HW label without One-hot encoding and the Correlation Optimization (CO) loss will have the best analysis performance. And we performed actual analysis on three data sets that are Subbytes operation part of AES-128 1 round. We verified our prediction by non-profiling analyzing two data sets with a total 16 of MLP-based model, which we describe.
