An ozone condensation system is evaluated from the viewpoint of an ozone supplier fro oxide thin film growth. Ozone is condensed by the adsorption method and its concentration is analyzed using the thermal decomposition method, The concentration of ozone exceeds 90mol% and ozone is supplied for a sufficiently long time to grow oxide thin films. Investigation of the ozone decomposition rate demonstrates that ozone can be transferred into the film growth chamber without marked decomposition. The ozone concentration is also evaluated using a quardrupole mass analyzer and the accuracy of this method is compared with the results of the thermal decomposition method.

The importance of intellectual property is increasing in the knowledge and information era. An organization that embraces technology and strategy is faced with promising opportunities and managerial difficulties. Forecasting the performance of technology and the underlying costs to achieve such performance is even more difficult than before. Those organizations that employ technology as part of their strategic arsenal know that they are running serious risks, which clearly increases the uncertainty of organizational performance. Therefore forecasting the performance of technology is a difficult task since technology has been characterized by intangible and tacit factors and traded in a supplier's market. The decision makers usually face a complex system of interrelated components, such as resources, desired outcomes or objectives. This study intends to evaluate the contribution of technology in intangible assets by the Analytic Hierarchy Process.

Considering the growth of blockchain technology, the research aims to transform the efficiency of recommending optimal coffee suppliers within the complex supply chain network. This transformation relies on the extraction of vital transactional data and insights from stakeholders, facilitated by the dynamic interaction between the application interface (e.g., Rest API) and the blockchain network. These extracted data are then subjected to advanced data processing techniques and harnessed through machine learning methodologies to establish a robust recommendation system. This innovative approach seeks to empower users with informed decision-making abilities, thereby enhancing operational efficiency in identifying the most suitable coffee supplier for each customer. Furthermore, the research employs data visualization techniques to illustrate intricate clustering patterns generated by the K-Means algorithm, providing a visual dimension to the study's evaluation.

The purpose of this research was to develop a smart wear equipped with wearable technologies for women in the age of 50's and 60's and confirm its acceptability. For this, we constructed a casual jacket that has the integration of heating and lighting function, and evaluated the user's satisfaction. The size of the heating device attached at the back of the jacket was 300 mm in width and 120 mm in length and the size of the one attached at the front abdomen was 180 mm in width and 120 mm in length. The power supplier was the unification of the battery and controller which have been waterproofed. The lighting device connected with LED was 26mm in width, 20 mm in length and 1.5 mm in thickness. It has been designed in a waterproofed rectangular shape and was attachable to the jacket. The satisfaction survey of a smart jacket has been conducted with three standards, which were convenience, appearance and practicality. Free physical movement among the standard of convenience had very high scores with the average of 4.7 on a five point-scale. The acceptability of the jacket was 4.6, which proved that it didn't have unique feelings compared to ordinary ones. The evaluation score of the appearance of the jacket was 4.5. Especially inside finishing of the jacket received the highest scores from all ages. According to the evaluation of practicality, there has been no change in the appearance of the jacket and the function of heating device after laundry.

The key success factors for Franchise Enterprise as a virtual company which is established based on franchise system are the competitiveness of sub-systems in franchise system such as franchisor, franchisee, vendor(supplier), and customer, and to sustain the symbiotic relationship among sub-systems. In this regard, evaluating franchise system is considered to be implemented in different contexts and methods comparing with extant evaluation system in franchise business which is more focused on the relationship between franchisor and franchisee. The flagship role of establishing franchise system is to be franchisor system, however, the symbiotic relationship among other sub-system including franchisee, vendor, and customer leads to successful Franchise Enterprise. The purpose of this study is to research existing evaluation systems for franchise business and to explore the model of evaluating franchise system, what is called, "Symbiosis Index".

In the domestic data exchanging market, unreasonable pricing of purchase data is consistently mentioned as a major obstacle in data trading. This is a problem caused by the inability to properly evaluate the value of data products due to lack of product information and experience in using them. In order to activate trading, the data exchanges need to provide information that allows consumers to comprehensively judge the value of data products in addition to prices. The cost-based, income-based, and market-based methods, which are mainly applied to data valuation, are insufficient as data valuation methods to stimulate trading and distribution because only price information, a result of valuation from a supplier's point of view, can be shared with consumers. This study aims to develop a measurable valuation method that allows data trading stakeholders (exchanges, suppliers, and consumers) to judge and share the value of data products from a common perspective. To this end, we identified the value drivers of data products, which are considered important in overseas data exchanges and related research, and derived an evaluation method that can quantitatively measure each value driver. In addition, evaluation criteria in the form of a rating table were developed using data products for transactions, and a value evaluation index was developed through stratification analysis (AHP) to enable relative value comparison. As a result of applying the evaluation criteria to actual data products, it was found that the evaluation values were differentiated according to the characteristics of individual data products, so it could be used as a relative value comparison tool.

The uncertainty of measurement in quantitative analysis of ammonia by continuous-flow analysis method was evaluated following internationally accepted guidelines. The sources of uncertainty associated with the analysis of ammonia were the weighing of sample, the preparation of extracting solution, the addition of extracting solution into the sample, the reproducibility of analysis and the determination of water content in tobacco, etc. In calculating uncertainties, Type A of uncertainty was evaluated by the statistical analysis of a series of observation, and Type B by the information based on supplier's catalogue and/or certificated of calibration. It was shown that the main source of uncertainty was caused by the volume measurement of 1 mL and 2 mL, the purity of ammonia reference material in the preparation of standard solution, the reproducibility of analysis and the determination of water content of tobacco. The uncertainty in the addition of extraction solution, the sample weighing, the volume measurement of 50 mL and 100 mL, and the calibration curve of standard solution contributed relatively little to the overall uncertainty. The expanded uncertainty of ammonia determination in burley tobacco at $95\%$ level of confidence was $0.00997\%$.

The source transfer receiver model ('Source $\times$ Transfer = Response' model) which is widely used by NVH development process of vehicle/transport/machinery to analyze effectively and manage efficiently the structural dynamic behavior is also applicable to construction structure. If the evaluation assessment of the vibration level does not meet the target level, there are two methods, one is source treatment or replacement and the other is the reduction treatment on the transfer structure. In case of source treatment, it is done by source supplier and so, the latter is more practical method to reduce the vibration level. In this study, in order to get the accurate Transfer FE model(floor structure FE model), Experimental modal analysis of part of floor structure and FEM modal analysis of full floor structure are performed, then updating of FE model is performed after correlation analysis between these two results and finally, the modal model and FRF are compared between FE and Experimental results.

Recently, an advanced raw material supplying system in diecasting industry that molten metal produced by the raw material supplier can be directly delivered to the diecasting shops was proposed. It was known to have advantages of reducing melting process cost and improving working environment. However, for its successful mass production, the development of high insulation ladle is inevitable. In this study, the optimal mixing ratio of $SiO_2-Al_2O_3$ was investigated and the high insulation ladle with computer simulation result was built in a prototype and evaluated. The prototype which has refractory wall of $SiO_233%-Al_2O_3$ 35%-CaO 33% showed high insulation sufficient for carrying the Al molten metal for 138 minutes. Gas quantity result and SEM-EDS analysis on the melt poured in the ladle also showed extremely low level of 0.028 cc / 100 g and no penetration of Al molten metal into the refractory wall, satisfying the requirements for mass production.
