This is an analysis of international mobile displays industry. There has been severe competition in market and technology. In technology, There has been competition between Japan, USA and Korea. On the other hand, there has been competition in the products market between Korea, Japan and Taiwan. Recently Korea has catched-up Japan in mid-size display industry. The response of Japanese firms are as follows: technological collaboration with Taiwanese firms in mid-size and concentration in small and large size displays. New competition, however, has started, since new technologies such as TFT-LCD and OELD have been used in products.

The conventional closed-die forgings had been applied to the forging of spur gears. But the forgings require high forging-pressure. In this paper, new precision forging technology have been developed. The developed technology is two steps forging process. Good shaped products are forged successfully with lower forging-pressure than those of conventional forging. The accuracy of the forged spur gear obtained by new precision forging technology is set nearly equal to that of cut spur gear of fourth and fifth class in Korean industrial standard.

Next Highly sophisticated communication generation of the Advanced Electronics and Imaging processing society will require a vast information volume and super high speed signal transport and information instruction. This means that super high technology should be created for satisfying the demand. It's also required the high reliability of the communication system itself, It will be supported the new advanced packaging technology of the 3 Dimensional structured system and system integration technology. Here is introduced the new 3 Dimensional technology for IC nnd LSI packaging and Opt-electronics Packaging of ASET activity in Japan.

Transgenic animal technology has provided new opportunities in many aspects of biotechnology and medicine during two decades. Several gene delivery systems including pronuclear injection, retroviral vectors, sperm vectors, and somatic cell cloning have been tried to generate new functional animals. In the future somatic cell cloning technology will be a major method in the transgenic animal production. Many factors enhancing overall transgenic efficiency should be overcome to facilitate the industrial applications of transgenic technology. Transgenic animal technology has settled down in some areas of the medicine, especially the mass production of pharmaceutical proteins and xenotransplantation. Thus, animal biotechnology will contribute to welfare of human being.

A chemical investigation of the stem bark of Melia azedarach var. Japonica (Meliaceae) has led to a new limonoid, 12-hydroxyamoorastatone (1), whose structure has been elucidated by spectroscopic measurements including 2D-NMR. The 2D-NOESY experiment on its di-p-bromobenzoate derivative (1a) has established the relative configuration of 1.

Through the Bucherer-Berg method, new 5-alkylthiomethyl or 5-alkylsulfonylmethylhydantoins were prepared. The reaction of ethyl chloroacetate with these compounds gave 3-acetate and the subsequent hydrolysis with dilute sodium hydroxide resulted in 3-hydantoinacetic acid derivatives. These products are expected to exhibit anti-inflammatory and analgestic activities.

Considering the present and expected demand for human resources by the maritime community, its quantity and quality depend on the number of the ships and the technology applied to them. Scientific and economic developments in this community bring the intensive use of modem technology for many of ships operation. Generally it effects to reduce the quantity of manpower, while it increases the requirement of qualifications of human resources to utilize such advanced technology. Considering above, the maritime education, training and research activities should be revised and updated according to the demand of the community. Because of a difference between the transition of the demand for the human resources and development of the maritime education, training and research activities, there are two most common questions as “What to teach” and “How to teach”. The first question has been asked for many years. The contents of maritime education and training are always related to the existing maritime knowledge and technology and should be updated with consideration of changes of the demand namely “Globalisation of maritime community”. It brings globalisation of the maritime education, training and research activities. The second question is still keeping us busy to look for the best way. Presently traditional methods are used together with new system, while the use of sophisticated simulation, communication and information systems etc. and it is changing our understanding on teaching. This paper introduces the new role of Maritime Institutions from the viewpoints of the maritime education. training and research activities. The role of guide for seafarers and maritime companies is always essential and the concepts such as “Refreshment Training”, “On the Job Training”, “Lifelong” or “Continuous Training” bring new understanding to the training period, trainee's age and position. As a result, the maritime institutions should be ready for their new role, which is, in brief, guiding the maritime society, recommending and providing new learning environments, organising research and developments, performing the education, training and assessment, improving existing methods and developing new methods of the education, training and assessment.

Currently, in the field of spinal surgery around the world, various new technologies have been rapidly developed and applied to patients. The author believes that it is necessary to discuss whether these new technologies are being fully reviewed for efficacy and safety before being applied to patients. To consider this issue, the author analyzed the basic research data and clinical application process of the intradiscal electrothermal therapy, which was developed as a new technology for discogenic pain disease in the 2000s and has been widely used worldwide. As a result, it was found that this procedure has been performed on patients in a state where there is insufficient base research on efficacy and safety. The author judges that this case reveals an essential problem related to the clinical operation of new medical technologies in the field of spine surgery. Therefore, the author believes that in order to minimize the side effects that new medical technology in the field of spinal surgery may have on patients, more full-fledged basic research and higher clinical acceptance standards should be established.

This study examines online art platforms as a new type of informational technology and seeks to verify the impact of the user's perceived value and acceptance of new technologies on the behavioral intention about art platforms. For this, it was conducted to survey 489 users of the online art platform. Several emotional value, functional value, social value, and value for money were selected as perceived value variables, and performance expectancy, effort expectancy, and facilitating conditions were set as variables of new technology adaptation. As evident in the correlation with perceived values, emotional value and social value have a significant impact on all parameters of new technology adaptation, while functional values and value for money only affect facilitating conditions and behavioral intention, respectively. Furthermore, the impact of acceptance of new technologies confirms that performance expectancy and facilitating conditions affect behavioral intention. This study demonstrates the perceived value of online art platform users and the acceptance of new technologies. Therefore, it is expected that platform providers will be able to use it as primary data to understand and reflect user requirements.
