The embedded software has been become more important than the hardware in mobile systems in ubiquitous society. The improvement models such as CMMI(Capability Maturity Model Integration) and SPICE(Software Process Improvement and Capability dEtermination) are used to improve the quality of software in general systems. Software process improvement is also necessary for mobile embedded software development to improve its quality. It is not easy to apply the general software improvement model to the mobile embedded software development due to the high cost effectiveness and heavy process. On the other hand, XP has the characteristics on focused communications with customers and iteration development. It is specially suitable for mobile embedded software development as depending on customer's frequent requirement changes and hardware attributes. In this paper, we propose a framework for development small process improvement based XP(eXtreme Programming)'s practice in order to accomplish CMMI level 2 or 3 in mobile embedded software development at the small organizations. We design and implement the Mobile Embedded Software Process Improvement System(MESPIS) to support process improvement. We also suggest the evaluation method for the mobile embedded software development process improvement framework with CMMI coverage check by comparing other process improvement model. In the future, we need to apply this proposed framework to real project for practical effectiveness and the real cases quantitative. It also include the enhance the functionality of MESPIS.

Through a simple translation and analysis of the "Su$\acute{s}$uta-saṃhit$\bar{a}$(The fascinating tales) S$\bar{u}$trasth$\bar{a}$na(The Introduction)", I have summarized the results of the research into the $\bar{A}$yurveda Herbal theory. 1. The title of chapter 40 is "dravya-rasa-guṇa-vip$\bar{a}$ka-vij$\tilde{n}$anīya(Medcation Taste Nature Effects Digestion)", and it states theoretical knowledge on materia medica. It says that 'matter' is the most important thing, and that it decides the curing effect. Although it does acknowledge the reason behind the doctors that emphasized things like 'taste', it mainly has a critical tone. The difference in philosophies and medical theory can be seen when we compare this to the "Caraka-saṃhit$\bar{a}$", 'theory on taste'. 2. The title of chapter 41 is "dravya-vi$\acute{s}$eṣa-vij$\tilde{n}$anīya(A Discussion on the Characteristics of Materia Medica)", and the contents of the chapter have a similar tone to the thoughts of the S$\bar{a}$mkhya(數論派). All 'matter' was created by the combination of the five elements of earth, water, fire, wind, and ether, and the predominant element makes it have an earth, water, fire, wind, or ether nature. Earth has an unmoving and down going nature, and makes the body strong. Water has an irrigating nature, and moistens the tissue and induces secretion and excretion. Fire has an upward-going nature, and improves sight and complexion. Wind relaxes and dries the body, and makes the mind and body agile. Ether gives flexibility, porosity, and candidness. The title of chapter 42 is "rasa-vi$\acute{s}$eṣa-vij$\tilde{n}\bar{a}$nīya(A Discussion on the Types of Rasa(taste))". "Rasa" is an important concept in $\bar{A}$yurveda. Sometimes it is translated as 'one of the seven types of bodily tissue' and seen as chyle, and sometimes it is seen as the tastes that can be felt with the tongue such as spicy, sweet, sour, bitter, salty, and astringent(澁). Volume 1, chapter 42 of the "Caraka-saṃhit$\bar{a}$" is dedicated to the "types of taste", and in chapter 26, it theorizes the concept of 'taste'.

Modern radar system requires high spectral purity and low phase noise characteristics for very low RCS target detection and high resolution SAR (Synthetic Aperture Radar) image. This paper presents a new X-band high stable frequency synthesizer for high performance radar system, which combines DAS (Direct Analog Synthesizer) and DDS (Direct Digital Synthesizer) techniques, in order to cope with very low phase noise and high frequency agility requirements. This synthesizer offers more than 10% operating bandwidth in X-band frequency and fast agile time lower than 1 usec. Also, the phase noise at 10kHz offset is lower than -136dBc/Hz, which shows an improvement of more than 10dB compared to the current state of art frequency synthesizer. This architecture can be applied to L-band and C-band application as well. This frequency synthesizer is able to used in modern AESA (Active Electronically Scanned Array) radar system and high resolution SAR application.

IT system in supply chain management(hereafter, SCM) has been regarded as one of competitive advantage to win over competing supply chain. SCM participants rush to adopt IT system to be agile for changing environment. Companies expect the improvement of the process integration over the supply chain, which enhance the overall SCM performance. IT system has been considered to influence on effective communication over the wall of firm boundaries. But, the profitability or the effectiveness of IT investment are controversial. This study try to reemphasize the importance of IT system considering the differences of processes, and the influences on the collaboration of supply chain participants. We want to know the perception level of functional managers for the importances, usages, and contributions of IT system in manufacturing sector. Also, we compare the different perception for collaborative SCM among supplier, buyer, and employees of buyer, and try to understand the context in which the IT investment acceptance occurs. We collected 297 responses(199 from line process and 98 from project process respectively). Results show that the importances, usages, and contributions of IT system are higher in the line process than in the project process.

In recent competitive business environment each enterprise has to be agile and flexible. For these purposes run-time monitoring ofservices provided by an enterprise and early decision making through this becomes core competition of the enterprise. In addition, in order to process various innumerable events which are generated on enterprise systems techniques which make filtering of meaningful data are needed. However, the existing study related with this is nothing but discovering of service faults by monitoring depending upon API of BPEL engine or middleware, or is nothing but processing of simple events based on low-level events. Accordingly, there would be limitations to provide useful business information. In this paper, through situation detection an extended complex event model is presented, which is possible to provide more valuable and useful business information. Concretely, first of all an event processing architecture in an enterprise system is proposed, and event meta-model which is suitable to the proposed architecture is going to be defined. Based on the defined meta-model, It is presented that syntax and semantics of constructs in our event processing language including various and progressive event operators, complex event pattern, key, etc. In addition, an event context mechanism is proposed to analyze more delicate events. Finally, through application studies application possibility of this study would be shown and merits of this event model would be present through comparison with other event model.

Cloud computing is a computing term that evolved in the late 2000s, based on utility and consumption of computer resources. Google say that "Cloud computing involves deploying groups of remote servers and software networks that allow different kinds of data sources be uploaded for real time processing to generate computing results without the need to store processed data on the cloud. Cloud computing relies on sharing of resources to achieve coherence and economies of scale, similar to a utility (like the electricity grid) over a network. At the foundation of cloud computing is the broader concept of converged infrastructure and shared services. Cloud computing, or in simpler shorthand just "the cloud", also focuses on maximizing the effectiveness of the shared resources." The cloud service is a smart and/or intelligent service to save private files in any device, anytime, anywhere. Dropbox, OAuth, PAClous are required that the accumulated user's data are archives with cloud service. Currently we suggest an implementation technique to process many tasks to the cloud server with a thread pooling. Thread pooling is one of efficient implementating technique for client and service environment. In this paper, to present the implementation technique we suggest three diagrams in the consideration of software engineering.

Most of researchers and business futurists agree that traditional organizational designs are inadequate for coping with today's turbulent and increasingly networked world. Executives in small firms find that their organizations must tap into an extended network of partners to achieve the scale and power needed to succeed in industries dominated by large, global firms. As they attempt to build lean yet agile businesses, these executives are finding that they no longer rely on gut instinct alone. Neither can they simply copy organizational model that worked in the past. They must understand how organizational design choices influence operational efficiency and flexibility and, even more important, how to best align the organization with the environment and the strategy chosen to quickly and effectively sense and respond to opportunities and threats This research examines the capabilities required to build businesses that can survive and prosper in today's fast-faced and uncertain environment. The insights presented in this research have emerged from over 30 years of work with hundreds of executives and entrepreneurs as they struggled to build businesses that could cope with the demands of a rapidly changing, networked global economy. The insights from this research suggest that IT is an important enabler for developing the best capabilities required for success.

Recently, satellites equipped with high-performance electronics have required higher power consumption because of the advancement of satellite missions. For this reason, the size of the solar panel is gradually increasing to meet the required power budget. Increasing the size and weight of the solar panel is one of the factors that induce the elastic vibration of the flexible solar panel during the highly agile maneuvering of the satellite or the mode of vibration coupling to the satellite or the mode of vibration coupling to the micro-jitter from the on-board appendages. Previously, an additional damper system was applied to reduce the elastic vibration of the solar panel, but the increase in size and mass of system was inevitable. In this study, to overcome the abovementioned limitations, we proposed a high -damping yoke structure consisting of a superplastic SMA(Shape Memory Alloy) laminating a thin FR4 layer with viscoelastic tape on both sides. Therefore, this advantage contributes to system simplicity by reducing vibrations with small volume and mass without additional system. The effectiveness of the proposed superelastic SMA multilayer solar panel yoke was validated through free vibration testing and temperature testing using a solar panel dummy.

As the local manufacturing industry has entered a phase of stagnation, service and product design based on user experience has been highlighted as an alternative for the innovation. However, SMEs(Small and Medium-sized Enterprises) are still struggling to overcome the current crisis. One of the reasons is that SMEs do not have enough contact points with the validated UX firms and experts. Thus, SMEs has a high barrier to invest in new opportunity area, user experience. In this study, we aim to figure out UX experts' competence to perform the UX method to solve the UX problems based on the KSA framework(Knowledge, Skill, Attitude). Based on the literature review and expert workshop, we grouped the UX method according to the similarity of the competence required to conduct the method. With cluster analysis, 5 different groups of UX method were defined based on the competence, Panoramic Analysis, Meticulous Observation and Analysis, Intuitive Interpretation, Agile Visualization, and Logical Inspection. The results would be applied to compose a portfolio of UX experts and to implement a mechanism that could recommend the professional experts to the company.
