  • Japanese apricot (Prunus mume Sieb. et Zucc.) is the national symbol and was once the most important temperate fruit crop in Taiwan. Fruiting cultivars were originally introduced from southern China but commercial production was not significant until the 1970s. Currently 6,400 ha of Japanese apricot orchards distribute on shallow mountain hills in the central and the southern part of the island. Taiwanese commercial fruiting cultivars are plausibly chance seedlings or sports from the early introduction and are very low chilling required for budbreak. Ornamental cultivars have been mainly introduced from Japan but cultivations have been limited in high altitude area due to their high chilling requirement. In 2009, Taiwan Agricultural Research Institute's breeding program released the first low chill ornamental cultivar 'Tainung No.2' with a great ornamental potential in subtropical regions. Cultivation and production of Japanese apricot fruit in Taiwan continue to dwindle due to the declining Japanese market share. Ongoing industry transformation to increase domestic consumption and consumer's interest will sustain the future of Japanese apricot in Taiwan.

  • In an effort to increase the data capacity of one-dimensional symbology, 2D barcodes have been proposed a decade ago. In this paper, we present an effective 2D barcode detection algorithm from gray-level images, especially for the handheld 2D barcode recognition system. To locate the symbol inside the image, a criteria based on the block contrast is adopted, and a gray-scale projection with sub-pixel operation is utilized to segment the symbol precisely from the region of interest(ROI). Finally, the segmented ROI is normalized using the inverse perspective transformation for the following decoding processes. We also introduce the post-processing steps for decoding the QR-code. The proposed method ensures high performances under various lighting/printing conditions and strong perspective deformations. Experiments shows that our method is very robust and efficient in detecting the code area for the various types of 2D barcodes in real time.

  • In this paper, we propose a real-time two-dimensional bar code detection system even at long range using a vision technique. We first perform short-range detection, and then long-range detection if the short-range detection is not successful. First, edge map generation, image binarization, and connect component labeling (CCL) are performed in order to select a region of interest (ROI). After interpolating the selected ROI using bilinear interpolation, a location symbol pattern is detected as the same as for short-range detection. Finally, the symbol pattern is arranged by applying inverse perspective transformation to localize bar codes. Experimental results demonstrate that the proposed system successfully detects bar codes at two or three times longer distance than existing ones even at indoor environment.

  • In this paper, we propose a new function embedding method that can measure mathematical projections of probability amplitude, probability, average expectation and matrix elements of stationary-state unit matrix at all control operation points of quantum gates. The function embedding method in this paper is to embed orthogonal normalization condition of probability amplitude for each control operating point into a binary scalar operator by using Dirac symbol and Kronecker delta symbol. Such a function embedding method is a very effective means of controlling the arithmetic power function of a unitary gate in a unitary transformation which expresses a quantum gate function as a tensor product of a single quantum. We present the results of evolutionary operation and projective measurement when we apply the proposed function embedding method to the ternary 2-qutrit cNOT gate and compare it with the existing methods.

  • The performance of maximum likelihood(ML) detection for the given channel is analyzed in spatially multiplexed MIMO system. In order to obtain the vector symbol error rate, we define error vectors which represent the geometrical relation between lattice points. The properties of error vectors are analyzed to show that all lattice points in infinite lattice almost surely have four nearest neighbors after random channel transformation. Using this information and minimum distance obtained by the modified sphere decoding algorithm, we formulate the analytical performance of vector symbol error over the given channel. To verify the result, we simulate ML performance over various random channel which are classified into three categories: unitary channel, dense channel, and sparse channel. From the simulation results, it is verified that the derived analytical result gives a good approximation about the performance of ML detector over the all random MIMO channels.

  • In the global context, particularly in Christian nations, Christmas is considered a culturally and ethically significant time. In this study, we examine Charles Dickens' novel, "A Christmas Carol," and the celebration of Christmas in Korea. We explore the values of Christmas in Korea derived from the significance and importance of this novel. These values include repentance, empathy, compassion, and the importance of humanity. Korean Christmas is regarded as a time for practicing these values, bearing a message akin to the transformation of characters like Scrooge. Furthermore, "A Christmas Carol" conveys a message of improvement and change over time, emphasizing change and growth in Korean Christmas. People reflect on their past, correct their mistakes, nurture hope for the future, and experience personal growth and transformation. Additionally, the novel raises awareness of social injustice and inequality, offering alternatives. In Korean society, Christmas encourages the willingness to care for and help others, facilitating discussions and understanding of societal issues. For these reasons, "A Christmas Carol" is considered a culturally and ethically significant time in Korean Christmas, and the two are intertwined in various aspects. This study explores the interaction between cultural change and ethical teachings by 'A Christmas Carol' and investigates the impact of this work on Christmas culture and social change. It serves as the basis for emphasizing moral principles and humanity during the Christmas season, and this research provides suggestions for future research directions, aiming to deepen the understanding of Dickens' work and the importance of "A Christmas Carol." Through these efforts, it is expected that valuable insights into the connection between Christmas culture and moral messages will be gained. In this study, we will delve into the enduring appeal and cultural significance of "A Christmas Carol," discussing how this novel has evolved into a beloved holiday tradition and a true symbol of Christmas. We will also examine the adaptation of this novel into various media and its influence on holiday season celebrations. Insights into the impact of this novel on Korean society and its continued significance in modern times will be provided, suggesting a direction for a healthier and more desirable path for Korean society.

  • The Fourth Industrial Revolution is bringing about great changes in many industrial fields, and among them, active research is being conducted on convergence technology using artificial intelligence. Among them, the demand is increasing day by day in the field of object recognition using artificial intelligence and digital transformation using recognition results. In this paper, we proposed an optimal learning model construction method to accurately recognize letters, symbols, and lines in images and save the recognition results as files in a standardized format so that they can be used in simulations. In order to recognize letters, symbols, and lines in images, the characteristics of each recognition target were analyzed and the optimal recognition technique was selected. Next, a method to build an optimal learning model was proposed to improve the recognition rate for each recognition target. The recognition results were confirmed by setting different order and weights for character, symbol, and line recognition, and a plan for recognition post-processing was also prepared. The final recognition results were saved in a standardized format that can be used for various processing such as simulation. The excellent performance of building the optimal learning model proposed in this paper was confirmed through experiments.

  • This article started with 'encounter'. Both authors met around the middle of February and discussed the subject for the inhospital conference presentation scheduled at the break of June. Having conversation like "Movies similar to fairytales heard from childhood are standing out conspicuously among commercial films which are attracting audiences and receiving fervent response these days. This phenomenon is marvelous and mysterious." together, and sharing this and that, the conversation turned naturally to 'Bram Stoker's Dracula', 'Series of Twilight', and 'Warm Bodies', both authors found out the fact that we saw these movies in common with propound impression. Feeling our hearts beating high, bit of fear and hesitation followed simultaneously at the moment when both of us encountered the idea to choose subject of conference presentation related to this and expressed one in words. While preparing for the conference, presenting to others, and having discussion with the audience, our hearts have been filled with Presentation was finished after active discussion beyond fixed hour and it also brought audience (among those present) to show strong emotional response both positively and negatively. At first, we just had a thought to put aside the content of presentation, but we felt lack of something else, lingering in our minds. We finally decided to accomplish our work into an article leading to submission, based on the advice and recommendation from one of the audience. This article is a small 'creative writing' born by sharing both authors' passion and enthusiasm. In the first part of this article, we have introduced the dream of 31-year-old woman's which led to the 'creative writing' and spotlighted her personal life, before and after the dream. In the second part, we have examined the consequence (way of realization) and meaning of creative impulse shown from or experienced from personal unconsciousness (dream, fantasy) together. Creative impulse shown from the individual appeared to bring creative transformation of individual personality through the process of 'introversion'. Otherwise it also appeared to be delivered as a masterpiece through 'creative writing' or from the process of 'extroversion'. Sometimes both consequences happened at once. We tried to examine and interpret the dream of 31-year-old woman's, which was introduced in the first part of this article, that is to say, the dream of 'Stephenie Meyer's, the author of the 'love between vampire boy and ordinary human girl' themed novel 'Twilight Series', in a psychoanalytic perspective. In the third part, highlighting individual dreams and three different movies 'Bram Stoker's Dracula', 'Twilight Series', and 'Warm Bodies', we found the transformation of symbol 'Man of Darkness, vampire' seen in each individual dreams and in some specific popular arts, such as novels and movies, receiving fervent response from people. We also found love between this symbol and humane woman, bearing fruit together with very impressive change shown in the attitude of 'Man of Darkness' (vampire)'s conscious ego and mutual relationship pattern. We contemplated this phenomenon, the reason why these events happen, and what kind of association presents among these events, individual, and this era and discussed the effects on individuals and this era, at present. 'Creative impulse', originated in the deep structure of human mind is realized as a 'transformation of individual personality' or masterpiece through artistic creation. If it has a chance to make a match with this era, shared by a lot of contemporary people, it also appears to bring positive effect as healing and salvation to each individual or to each era. From this article, we mainly highlighted positive and healing aspects of individual 'creative impulse'. We hope to deal with the negative consequences and their reason coming from 'creative impulse', if the occasion arises, in the future with a new article.

  • This study researched the symbolic meaning of the costume colors in the independent film . The purpose of the study is to shed light on the relation between a film and the clothing color by exploring the symbolic meaning of costume colors as based on place images and as reflected in characters' internal psychological states and situations. The conclusions of this study are as follows. First, the colors primarily presented were neutral shades of black and white or dark, almost-black tones, representing the negative narrative structure and depicting the image of a human being. Second, a series of bright blue shades were presented to reflect the positive narrative structure of a human being returning successfully to reality. Third, the application of color, involving both the psychological aspect as well as the symbolism of color, was effectively delivered to the audience. Fourth, the emphasis on color in the smallest details of costumes was analyzed, and it was found that symbolic color effectively communicated the whole image of transformation as the story progressed, clearly delivered delicate emotional messages, and contained symbolism relating to particular places and situations.

  • The knots have been used practically and functionally in close relation to people's daily life, and it shows the beauty of its ornamental purpose. This study was to discover a new formativeness, such as the natural and symbolic beauty of knots, based on the interpretation of knots' basic image, recreating Korean beauty and characteristics within a modern sense. A bowknot is one of the beautiful Korean traditional knots and it is considered as a symbol of transformation. In this study, the formativeness of bowknots was shown and used, resulting in developing textile patterns that symbolize peace, love, joy, and hope. It was believed that the symbolism of bowknots could be suitable for a pattern of kindergarten uniforms which the children would experience for the first time. Considering the functional characteristics without discomfort while the children participate in various activities and movements, we made two pairs of boys' uniforms and two for girls.
