This paper provides an overview on development of long-span bridges monitoring in Japan, with emphasis on monitoring strategies, types of monitoring system, and effective utilization of monitoring data. Because of severe environment condition such as high seismic activity and strong wind, bridge monitoring systems in Japan historically put more emphasis on structural evaluation against extreme events. Monitoring data were used to verify design assumptions, update specifications, and facilitate the efficacy of vibration control system. These were among the first objectives of instrumentation of long-span bridges in a framework of monitoring system in Japan. Later, monitoring systems were also utilized to evaluate structural performance under various environment and loading conditions, and to detect the possible structural deterioration over the age of structures. Monitoring systems are also employed as the basis of investigation and decision making for structural repair and/or retrofit when required. More recent interest has been to further extend application of monitoring to facilitate operation and maintenance, through rationalization of risk and asset management by utilizing monitoring data. The paper describes strategies and several examples of monitoring system and lessons learned from structural monitoring of long-span bridges in Japan.

As a dental technician, the aim of the present study on maxillofacial prosthesis was to research its relation with dental technology and further development aspects by looking into its history, kinds, production materials and process. Dental technicians are to expect a great potential to work as maxillofacial prosthetist if having an interest in education of maxillofacial prosthesis field, and developing and operating the education process by expanding the range of dental technology. This article is to present overall history of maxillofacial prosthesis and some background information on the materials which have been used from the past. The maxillofacial field plays essential functions of mastication and speech, as well as performs appearance, which evokes good or bad feelings as an instant and instinctive response. The use of maxillofacial prostheses is not merely the replacement of a missing part of the face, resulted from injuries, but a rehabilitation process to help individuals come back to society. Rehabilitation includes both patient's physical and psychological recovery, such as self-esteem and selfconfidence. There has been a rapid development in application potentials of maxillofacial prosthesis technology which include implant, which can penetrate skin, and new materials. In order to produce maxillofacial prosthesis, general procedures of maxillofacial laboratory work should be understood first. Maxillofacial prosthesis and the dental prosthesis have many similarities in its academic perspective and originality. Maxillofacial prosthesis should be added into the curriculum for dental technology to achieve co-enhancement of the two fields.

As people have paid much attention to their health along with increased interest in high quality of living, they have managed their health in organized manners. Space is a physical field which directly and indirectly interacts with human life, there is a little research on its therapeutic aspect and it is only negatively applied for development of products and alternative medicine. This study aims to identify research trends and flows targeting previous research on therapeutic approaches in domestic space design and present basic materials on space design approaches in a therapeutic view, which will be helpful in ultimate development of space design in theories and practices. As a result, it was discovered that there were only a few papers which were searched with direct key words on curative environment, which indicates that specific studies as therapeutic approaches are insufficient. When the studies were analysed according to annual publications, research on residential welfare and medical space was active, and research on design methodology, design techniques, and design plans was active, but research on psychology, behaviors, laws and institutions was relatively insufficient, which indicates studies on physical and psychological aspects of space design are necessary. In conclusion, it is suggested that further studies on therapeutic environment for direct and specific persons should be defined and classified although there have been relevant studies in various fields.

Recently, with the rapid development in the oceanic systems such as the oceanic structures and vessel, there occurs much interest in the impingement erosion-corrosion. In this paper, Cu-metal was tested by using of erosion apparatus with water-jet type and was investigated under the behaviour of impingement erosion-corrosion according to various environmental conditions, and the properties of Cu-metal were evaluated through the measurement by weight loss, weight loss rate, protective efficiency. The results were compared with those obtained using Cu-metal applied to cathodic protection and Cu-alloys added to Zn or Al-metal. As a basis of those results, the best protective efficiencies could be taken as using cathodic protection method and Cu-alloy with Al & Zn material addings, and will be suggested as the fundamental data of the anti-impingement erosion-corrosion on Cu-metal of impeller material for oceanic centrifugal pump.

There has recently been Increased interest in the emotional intelligence (EQ) of elementary school students, which is recognized as a more important value than IQ (intelligence quotient) for predict of their success in school or later life. However, there are few sensory education programs, available to improve the EQ of elementary school student's in Korea. This study was conducted to develop an educational program that reflects the characteristics and contents of traditional rice culture and verify the effects of those programs on the EQ of children. The program was developed based on the ADDIE (Analysis, Design, Development, Implementation and Evaluation) model and participants were elementary school students in $3^{rd}$ and $4^{th}$ grade (n = 120) in Cheonan, Korea. Descriptive statistics and paired t-tests were used. EQ scores pertaining to the basic sense group, culture group, and food group were significantly improved after the sensory educational program(P < 0.05), but no change was observed in the control group. These findings indicate that sensory education contributed to improving elementary school children's Emotional Intelligence (EI) and their actual understanding about Korean traditional rice culture.

Mammalian neural stem cells (NSCs) are of particular interest because of their role in brain development and function. Recent findings suggest the intimate involvement of programmed cell death (PCD) in the turnover of NSCs. However, the underlying mechanisms of PCD are largely unknown. Although apoptosis is the best-defined form of PCD, accumulating evidence has revealed a wide spectrum of PCD encompassing apoptosis, autophagic cell death (ACD) and necrosis. This mini-review aims to illustrate a unique regulation of PCD in NSCs. The results of our recent studies on autophagic death of adult hippocampal neural stem (HCN) cells are also discussed. HCN cell death following insulin withdrawal clearly provides a reliable model that can be used to analyze the molecular mechanisms of ACD in the larger context of PCD. More research efforts are needed to increase our understanding of the molecular basis of NSC turnover under degenerating conditions, such as aging, stress and neurological diseases. Efforts aimed at protecting and harnessing endogenous NSCs will offer novel opportunities for the development of new therapeutic strategies for neuropathologies.
