This study is about to reveal the connections and the importance of China's country image, product image, and purchase intention. Following are the results of the empirical analysis summary. First, in country's national image, except political image, economic image and cultural image have a positive (+) impact on the product image is true. Secondly, a country's product image have a positive (+) impact on purchase intention. Therefore, consumer tend to improve purchase intention when China's product image increase. In summary, consumers' purchase intention can obtain the best positive result, when a country's national image is set as the core factor, which combines and improves concurrently with one's product image.

A direct authentication from gray-scale image, instead of the conventional multi-step preprocessing, is proposed using Gabor filter-based features from the gray-scale fingerprint around core point. The core point is located as a reference point for the translation invariant matching. And its principal symmetry axis is detected for the rotation invariant matching from its neighboring region centered at the core point. And then fingerprint is divided into non-overlapping blocks with respect to the core point and features are directly extracted form the blocked gray level fingerprint using Gabor filter. The proposed fingerprint authentication is based on the Euclidean distance between the corresponding Gabor features of the input and the template fingerprints. Experiments are conducted on 300${\times}$300 fingerprints obtained from a CMOS sensor with 500 dpi resolution, and the proposed method could lower the False Reject Rate(FRR) to 18.2% under False Acceptance Rate(FAR) of 0%.

Due to the proliferation of software parallelization on multi-core CPUs, the number of concurrently executing processes is rapidly increasing. Unlike processes running in a server environment, those executing in a multi-core desktop or a multi-core mobile platform have various correlations. Therefore, it is crucial to consider correlations among concurrently running processes. In this paper, we exploit the property that for a given created location in the binary image of the parent process, the average running time of child processes residing in the run-queue differs. We claim that this property can be exploited to improve the overall system performance by running processes that have a relatively short running time before those with a longer running time. Experimental results verified that the running time was actually improved by 11%.

This study was conducted to estimate deterioration reason of jointed concrete pavement. Image analysis tests were performed according to ASTM C 457 using concrete core specimens. Durability factors were estimated according to spacing factor, which is related with air content and air-void information. Test results show that spacing factors of most specimens were estimated above 250$\mu$m so that investigated concrete pavement has the problem of freeze and thawing resistance.

This study was carried out to investigate sheet properties of Indian mallow hanji, made by different pulping methods such as alkali and sulfomethylated pulpings, and different stock compositions, various mixing ratios of bast fiber and woody core fibers. Effect of morphological properties of pulp stocks on the sheet formation and their optical properties were also evaluated using an image analyzer and confocal laser scanning microscope(CLSM). In addition, the effect of fiber distribution index(FDI), which was calculated based on the image in a z-direction of a sheet from CLSM, on the sheet properties of Indian mallow hanji was discussed. The proposed FDI had a good correlation with various properties of paper, such as apparent density, opacity, tear index, breaking length and zero-span tensile strength. Especially, sulfomethylated pulp sheets＇FDI was higher than alkali pulp sheets.

An automatic visual classification system is introduced which provides for measuring the length and diameter of coilform cores and dividing them into 5 different classes in terms of how far their length be from the desired length. This task is fully automated by controlling two STEP motors and by using image processing techniques. The classification procedure is broken into three logical parts. Fist, cores in the form of randomly stacked bundle are lined up one by one so as to be well captured by a cameras. The second part involves capturing core image. Then, it enters the measuring process. Finally, this machine would retain all tire information relating to the length. According to the final result, cores are sent to the corresponding bin. This considerably simplifies the selecting task and facilitates a greatly improved reliability in precision. The average classifying capability about 2 pieces per second.

This paper explores the optimal processing element (PE) configuration for ultrasonic image processing at different resolutions ($256{\times}256$, $768{\times}1,024$, and $1,024{\times}1,280$). To determine the optimal PE configuration, this paper evaluates the impacts of a data-per-processing element (DPE) ratio that is defined as the amount of image data directly mapped to each PE on system performance and both energy and area efficiencies using architectural and workload simulations. This paper illustrates the correlation between DPE ratio and PE architecture for a target implementation in 130nm technology. To identify the most efficient PE structure, seven different PE configurations were simulated for ultrasonic image processing. Experimental results indicate that the highest energy efficiencies were achieved at PEs=1,024, 4,096, and 16,384 for ultrasonic images at $256{\times}256$, $768{\times}1,024$, $1,024{\times}1,280$ resolutions, respectively. Furthermore, the maximum area efficiencies were yielded at PEs=256 ($256{\times}256$ image) and 4,096 ($768{\times}1,024$ and $1,024{\times}1,280$ images), respectively.

Purpose: This study examines the influence and the relevance of personal background factors, social activity factors, and satisfaction factors for university education of college students in terms of changes in core competencies required by companies, so as to provide basic data for developing a curriculum necessary for improving core competencies. Methods: A self-administered questionnaire survey was administered to 172 college students from the Department of Dental Laboratory Technology at K University in Gangwon Province, who understood the purpose of this study and agreed to participate, from September 10, 2022 to September 30, 2022. Results: 1. The core competency scores of university students in the dental technology department for teamwork was 3.91±0.65, creativity was 3.66±0.70, challenging spirit was 3.64±0.74, professionalism was 3.54±0.74, global was 3.29±0.69. 2. To enhance the core competencies of college students in the dental technology department, it is necessary to improve the satisfaction with the curriculum through the expansion of educational infrastructure, and help in the career decision and preparation process. Conclusion: It is necessary to seek research that identifies the core competencies of dental technicians and university students based on the image of human resources desired by companies in a more diverse way and programs necessary to promote them.

Since construction work is an indispensable part of daily lives, complaints of noise are unavoidable. Noise control in construction sites is normally known as a regulation by a government and self-motivated noise controls rarely occur. In this paper, a marketing strategy is proposed to provide a potential value of noise control for real estate developer. First, people's perception to construction noise was examined in means of collecting and analyzing media reports between 2005 to 2011. Then decibel test was done in order to test noise generated by different devices in a construction site in various distances. According to the theory of core competency, a conceptual model was raised to illustrate profit and loss situation of the real estate developers in the case they invest more in noise control. The construction noise is discussed that it will ruin people's perception to the company's brand image and reputation. Also, the investment in the creation of silent site is discussed that it will not only bring benefit to the brand image work but also have value of profit in the market.
