In many organisms, trehalose has been Down as an energy source and a protectant against various environmental stresses such as desiccation, freezing, heat and osmotic pressure. Previously, we have isolated and characterized the genes encoding trehalose-6-phosphate synthase (ZrTPS1) and trehalose-6-phosphate phosphatase (ZrTPS2) from one of the most osmotolerant yeasts, Zygosaccharomyces rouxii. We have also generated transgenic plants by co-introduction of ZrTPS2 and ZrTPS2 into potato plant (ZrTPS2-2A-ZrTPS1 plant) in an attempt to metabolically engineer trehalose in the transgenic plant using the foot-and-mouth disease virus(FMDV) 2A system and to generate drought resistant crop plants. In this research, we assayed previously generated the ZrTPS2-2A-ZrTPS1 plant biofunctionally by drought treatment, and measured the amount of trehalose in the ZrTPS2-2A-ZrTPS1 transgenic plants. The ZrTPS2-2A-ZrTPS1 transgenic plant showed strong drought resistance in spite of little or no accumulation of transgenic in he transgenic plant compared with control plant.

Until a recent date, Toyota Production System (called TPS) was introduced by many domestic companies to remove waste and reduce manufacturing cost. However, cases of substantial and effective improvement after the introduction are not much. Even though many companies have actively conducted TPS during that time, the outcome is not satisfactory. In this paper, we show the problems and core contents to consider in applying of TPS as follows. First, the innovative organizational culture formed by active participation of employees and leadership of the CEO is very important for a successful introduction of TPS above all. Second, it is necessary to prepare various training programs optimized for the field in order to continuously improve the competency of employees in each class, and to train skilled personnel through that programs. Third, it is necessary to improve the maturity level of TPS application through the construction of correct evaluation system on accomplishment of the production system. In addition, the problems that occur should be solved through the continuous improvement activities. These results will help to TPS introduction of the domestic small-medium companies. Therefore, this study will contribute to strengthen and improve the global competitiveness in the related industries.

The Toyota production system (TPS) developed by Toyota corporation is a management principle and production model to improve values added through elimination of waste. Since the oil shock in 1970s, the TPS has drawn the worldwide attentions as a main factor of competitiveness of Japanese manufacturing system and has been studied and implemented in many countries regardless of size and types of industry. For the correspondence to various customer's requirement, it is required to establish on time delivery procedure and to shorten lead time. Therefore it intended to establish TPS which is adopted to 7 losses reduction and JIT(Just in Time). In this paper, the automatic production line for color TV manufacturing by TPS was developed and proved to push up two times of productivity, to reduce the 25 workers at a time, and to widen the flexibility of manufacturing from 14" to 25" TV.

In unlimited competitive period changed every time, domestic manufacturing industry feels a crisis between China and Japan, who are leaping to manufacturing strong countries with worldwide manufacturing factories. In this situation, many companies make an effort to learn and introduce Toyota production method drawing innovation of production method and reduction of many costs for high quality, but most of cases were failed. The reason for the failure should be that correct understanding and application of TPS corporate culture were insufficient and job attitude was not considered when applying Toyota production system. Therefore, the purposes of this thesis are to arrange major contents based on relative documents of precedent researchers, conduct a survey for employees of middle and small scaled manufacturers who introduced Toyota production system, analyze changes of enterprises' job attitude by introduction of TPS corporate culture and the effects on company's management results through the various analyses for grasping relationship among TPS corporate culture, job attitude and management results, introduce Toyota production system more effectively and suggest measures to maximize company's long-term management results.

In this paper, we propose the TPS (TPM-enhanced Privacy Protection System) which is an automated privacy protection system enhanced with a TPM (Trusted Platform Module). The TPS detects documents including personal information by periodic scanning the disk of clients at regular intervals and encrypts them. Hence, system manages the encrypted documents in the server. In particular, the security of TPS was greatly enhanced by limiting the access of documents including the personal information with regard to the client in an abnormal state through the TPM-based platform verification mechanism of the client system. In addition, we proposed and implemented a VTF (Virtual Trusted File) interface to provide users with the almost identical user interface as general document access even though documents containing personal information are encrypted and stored on the remote server. Consequently, the TPS automates the compliance of the personal information protection acts without additional users' interventions.

Introduction: With the development of dose calculation algorithms for electron beams, 3D RTP systerns are available for electron beam dose distribution commercially. However, no studies evaluated the accuracy of dose calculation with ADAC Pinnacle system for electron beams. So, the accuracy of the ADAC system is investigated by comparing electron dose distributions from ADAC system against the BEAMnrc/DOSXYZnrc. Methods: A total of 33 breast cancer patients treated with 6, 9, and 12MeV electrons in our institution was selected for this study. The first part of this study is to compare the dose distributions of measurement, TPS and the BEAMnrc/DOSXYZnrc code in flat water phantom at gantry zero position and for a 10 ${\times}$ 10 $\textrm{cm}^2$ field. The second part is to evaluate the monitor unit obtained from measurement and TPS. Adding actual breast patient's irregular blocks to the first part, monitor units to deliver 100 cGy to the dose maximum (dmax) were calculated from measurement and 3D RTP system. In addition, the dose distributions using blocks were compared between TPS and the BEAMnrc/DOSXYZnrc code. Finally, the effects of tissue inhomogeneities were studied by comparing dose distributions from Pinnacle and Monte Carlo method on CT data sets. Results: The dose distributions calculated using water phantom by the TPS and the BEAMnrc/ DOSXYZnrc code agreed well with measured data within 2% of the maximum dose. The maximum differences of monitor unit between measured and Pinnacle TPS in flat water phantom at gantry zero position were 4% for 6 MeV and 2% for 9 and 12 MeV electrons. In real-patient cases, comparison of depth doses and lateral dose profiles calculated by the Pinnacle TPS, with BEAMnrc/DOSXYZnrc code has generally shown good agreement with relative difference less than +/-3%. Discussion: For comparisons of real-patient cases, the maximum differences between the TPS and BEAMnrc/DOSXYZnrc on CT data were 10%. These discrepancies were due in part to the inaccurate dose calculation of the TPS, so that it needs to be improved properly. Conclusions: On the basis of the results presented in this study, we can conclude that the ADAC Pinnacle system for electron beams is capable of giving results absolutely comparable to those of a Monte Carlo calculation.
