Purpose: This study investigated perception and plan of dental technologists regarding the old age and retirement for them to enjoy stable old age. Methods: Dental technologists working in Seoul, Incheon, and Gyeonggido were asked to fill out a self-administered questionnaire, and a total of 200 copies were used for analysis. The collected data were statistically analyzed by using SPSS 22.0(Statistical Package for Social Sciences. Chicago, IL, USA) (a=0.05). In order to compare perception toward old age preparation among the subjects, a Chi-square test was performed, and, to investigate the level of preparedness for old age according to general characteristics, t-test was performed. Results: In the analysis of the old age preparedness by age, there was a significant difference in financial preparation, Asset identification, use of retiring allowance, information gathering, senior town home, and stability (p<0.05). To the questions regarding perception toward retirement, the majority of the subjects (60.5%) answered they had thought about retirement, and many (23.9%) of them attributed the reason to job stress (23.9%). Regarding old age preparedness according to workplace, there was a significant difference in use of retirement allowance and education for old age preparedness between general dental laboratories and general hospitals (p<0.05). Conclusion: It is believed that, for preparation of dental technologists for stable old age, in addition to their personal effort, it is important to provide social support and practical measures to ensure welfare and retirement.

The product lifecycle of a marine vessel can be classified into the design-production, operation-maintenance, and disposal phases. During the operation and maintenance phase, status data should be gathered from the major machinery and instruments installed on the marine vessel in order to perform efficient maintenance work. Although a PLM (product lifecycle management) system can manage the product information during the design and assembly stage, a PLM based on asset management technology is more appropriate for product information management during the operation stage. Product embedded information devices (PEIDs) are suggested for gathering real-time maintenance information during the operation and maintenance lifecycle. A PEID allows PLM to provide the capability of offering active information exchange between the lifecycle management system and equipment. This study designed a PEID to effectively obtain information and interact with a PLM system. It consists of sensors, wireless communication, and a micro-processor, which allow it to accumulate status data on the PLM system. The embedded information device and PLM enable the seamless information flow, tracking, and updating of MRO (maintenance repair and overhaul) information for a product throughout the middle of the product lifecycle.

In modern city, art museum is regarded as significant institutions because it includes educational roles beyond the means of facilities for historical exhibitions. Based on these flow, various research of museum's space with view from the operational point to the spatial analysis point has been approached. Moreover, it is required to address human behavior in art museum space on the ground that lots of audience move simultaneously. In the field of interior architecture, it is also necessary to analyze how design elements affect the human behavior directly and use the method of controling a circulation. In this research, based on the role and importance of the basic components of the interior space, re-interprets the exhibition space based on the relevant theory, to comprehensively examine the influence the shape of the space is on the substantially walking behavior. Therefore, first is to determine whether the spatial type corresponding to the position of the connectors in the exhibition space. Second is to conduct the investigation observation for gathering the actual viewing exhibition circulation. Finally, it analyzed whether the observed actual circulation and planned circulation matched. As the result, the position of the connectors is that causes the difference of the spatial configuration, which affects the viewing circulation was found. The significance of the research is to present the form to plans of the interior space as a method of reducing congestion perception of viewing circulation.

This study conducted an analysis of the current use of and satisfaction with 40 village-unit core facilities that were created through a village-building project in Busan targeting users and non-users of the facilities. The study then examined ideas to promote the availability of the facilities. The results showed that for the users, they had been using the facilities for gathering and information-sharing, and the facilities were improving the interactions among the locals. In terms of non-users, the study confirmed that any relevant fields should develop diverse programs, start promotions in various ways and establish networks among neighbors to increase the non-users' use of the facilities In addition, the study found that the village-unit core facilities are working to encourage interactions among residents and that the locals' voluntary participation in operation of the facilities are needed. The study also suggested that networks across the local communities and diverse programs should be formed and developed.

This paper deals with the development of the safety lancet and the electric lancing device. The safety lancet, in which a needle and a protective cap become one body, is designed. It is to prevent the secondary contamination by needlestick injury because the needle is always in the protective cap except for a moment of blood-gathering. The electric lancing device powered by batteries is devised to be operated by the moving rod of solenoid hitting the lancet. and to be used after selecting the repeat or the single hitting mode. The impact force by a hitting rod, the expected life of battery and etc. are measured for product development. This lancing device can be also used for the bloodletting device of the oriental medicine.

The purpose of this study is to review the literatures on the evolutionary perspective on education and to draw the educational implications for science education. This study addresses on several topics as follows: our common misunderstandings about the evolutionary perspective on education; children's inherent knowledge and abilities, their learning about the evolutionarily novel knowledge and abilities in school, their difficulties in academic learning, and the instructional strategies to cope with the difficulties; and the implications for science education from the evolutionary perspective. The evolutionary perspective on education has provided new insights how culturally important information is transmitted across generations in the past hunting-gathering societies and the modern societies, and how children's inherent motivational and behavioral dispositions affect their academic learning. In addition, the new perspective on education can be used to generate empirical hypotheses about children's science learning, and with the further research, could lead to useful implications and ultimately improve educational outcomes.

It has been reported that E. senticosus is effective for strengthening the liver, reduction of blood sugar levels, antistress and rainforcement of stamina. However, most of the extraction from this medicinal plant is imported from foreign countries. Therefore, farmers have tried to grow it in this country even though it is difficult to propagate by seeding method. This study was carried out to improve seeding propagation using seeds in National Honam Agricultural Experinment Station from '92 to '93. The seeds of E. senticosus were immature embryo at the time of gathering seeds in autumn, and needed wet stratification treatment for after-ripening. Embryo elongated slowly for a few days after stratification treatment, and cotyledon started to develop from 40 days after treatment. There were significantly positive correlation between after-ripening period and the ratio of embryo length. Dehiscence was the highest in the ratio of embryo length of 60∼70％, and percentage of dehiscent seed after treatment for 150 days was 76.5％.
