Alfalfa (Medicago sativa L.) is one of the most important forage legumes in the world. It has been demanded to establish the efficient transformation system in commercial varieties of alfalfa for forage molecular breeding and production of varieties possessing new characteristics. To approach this, genetic transformation techniques have been developed and modified. This work was performed to establish conditions for effective transformation of commercial alfalfa cultivars, Xinjiang Daye, ABT405, Vernal, Wintergreen and Alfagraze. GUS gene was used as a transgene and cotyledon and hypocotyl as a source of explants. Transformation efficiencies differed from 0 to 7.9% among alfalfa cultivars. Highest transformation efficiencies were observed in the cultivar Xinjiang Daye. The integration and expression of the transgenes in the transformed alfalfa plants was confirmed by polymerase chain reaction (PCR) and histochemical GUS assay. These data demonstrate highly efficient Agrobacterium transformation of diverse alfalfa cultivars Xinjiang Daye, which enables routine production of transgenic alfalfa plants.

This paper proposes a novel algorithm to recognize the curve of a structured road. The proposed algorithm uses an LCF (Lane Curve Function) obtained by the transformation of a parabolic function defined on world coordinate into image coordinate. Unlike other existing methods, the algorithm needs no transformation between world coordinate and image coordinate owing to the LCF. In order to search for an LCF describing the lane best, the differential comparison between the slope of an assumed LCF and the phase angle of edge pixels in the LROI (Lane Region Of Interest) constructed by the LCF is implemented. As finding the true LCF, the lane curve is determined. The proposed method is proved to be efficient through various kinds of images, providing the reliable curve direction and the valid curvature compared to the real road.

The main purpose of the present study was to investigate coordinate transformation based on two different systems: one was the World Geodetic System 1984(WGS84) adopted as a reference system for GPS satellite surveying;and another was the current Korean geodetic system based on Bessel ellipsoid. For this purpose, three methods were used to determine 7 parameters as follows: Bursa-Wolf model, Molodensky-Badekas model, and Veis model. The coordinate transformation was carried out using simillity transformation applied the obtained 7 parameters and the precision of transformed coordinate was evaluated. From this results, we found that Bursa-wolf model is more suitable than others for the determination of transformation parameters in Korea.

Shape memory alloys (SMA) have been emphasized, studied and understood in the controlled world of the laboratory. Any attempt to implement one of these alloys in engineered products requires a jump from the controlled world of the laboratory to the actual environment of the application. The first step is to move from single grain specimens to multigrain samples. One works with a material for which any stock is different from that previously available. This paper reviews the milestones in the familiarization process the authors had to overcome during their cooperation within a project funded by the European Union. The main items cover transformation temperatures, thermal treatment and properties understanding.

This paper presents a method of analog signal processing for a coordinate transformation. Through the proposed method, two-dimensional position information obtanided from any type of null-detector can be transformed into the information with repect to world coordinate system. In order to implement the method, a null- detection device which consists of four optical proximity sensor is developed. Through the experiments for performance evaluation, the effectiveness of the proposed method has been demonstrated.

In this thesis, we work on the curve recognition with real time processing and the Robot tracking method on recognized curve. Image information of segment curve is supplied to computer to run to a Robot so that it is a feedback system. Image coordinate frame to world coordinate transformation represents in this paper and curve matching algorithm subscribes by two method, first transformation matching algorithm, second image coordinate matching algorithm. Also Robot running time to computer image processing time relationships finally includes.

Asia is becoming a stronghold for innovation careers along with its resurgence in economic, political, and cultural arenas. This transformation happened on the backdrop of growing enrolments in higher education, increasing investments in scientific research & innovation, and innovation supportive policy measures by several Asian countries. Research and Development (R&D) and product customization centres of multinational corporations (MNCs) sited in emerging nations are also instrumental in this transformation.

The purpose of this article is to investigate communal action in the Ox Seeking Pictures of Daesoon Thought as an expression of future prospects. The Ox Seeking Pictures in Daesoon Thought seeks out renewal of thought, renewal of life, and true living. Here, the Ox Seeking Pictures symbolize a world in which good fortune comes true according to faith in Gucheon Sangje. The correlation between searching for the ox and the supporting teachings of the Reordering Works of Heaven and Earth in Daesoon shows the transformation of Daesoon prospects for achieving the renewal of thought. The correlation between Deep Contemplation Leading to Awakening and Finding and Following Heavenly Teachings shows the transformation of Daesoon reason into a practice implemented in daily life. The correlation between a human being's awareness and the heavenly paradise of the Later World shows transformation into true living based on everyday practice and the practical transformation of one's livelihood. In this investigation, we can say that the Ox Seeking Pictures of Daesoon symbolizes the realization of human dignity and respect for lives. No life should be destroyed or violated by another. Heaven, Earth, and Humanity can be changed and born anew. The visions of the realization of the heavenly paradise of the Later World show that this paradise in the world results from Daesoon principles. This provides a unique insight when compared to the bodhisattva ideal conveyed through the Ox Seeking Pictures of Mahayana Buddhism. Daesoon's Ox Seeking Pictures consist of a three-way interlocking of renewal of thought, implementation in life, and the practical transformation of one's livelihood. The communal spirituality based in Daesoon Truth connects and mediates among people and appears in three aspects. Firstly, it is thought to be a vision of the renewal of thought through the 'Virtuous Concordance of Yin and Yang.' Secondly, it is thought to be the vision of a new life based upon the spirit of Mutual Beneficence. Thirdly, it is thought to be a vision of true living through the realization of human dignity. Because of the appearance of the Ox Seeking Pictures of Daesoon Thought, this narrative picture shows the oxherd as searching for an ox which is the symbol of Daesoon Truth and Dao. Even though he catches the ox, he is still holds the rope to tie the ox to himself. He makes an effort to keep the ox steady. Finally, the oxherd's enlightenment becomes the source of responsibility to help unenlightened people in their struggles. In conclusion, it is necessary to interpret these paintings as the start of the Later World.

Cymbidium is horticulturally important and has been one of the most commercially successful orchid plants as well as cut flowers around the world including Korea. Up to now, a huge number of elite Cymbidium cultivars have been released on the commercial market via cross-hybridization, mutation and polyploidization breeding techniques. To investigate on breeding system in Cymbidium, we inquired the brief history and techniques of breeding and the current status on Cymbidium breeding in Korea. Also, the general propagation process of elite Cymbidium lines via tissue culture should be presented. However, the slow process of conventional breeding and the lack of useful genes in Cymbidium species delays the introduction of new cultivars to the commercial market. To solve these limitations, efficient regeneration and genetic transformation systems should be established in the improvement of Cymbidium breeding program. During the last several decades, some progress has been made in tissue culture and genetic transformation in Cymbidium species. We review the recent status of tissue culture and genetic transformation systems in Cymbidium plants.
