This study examines the differences in the various characteristics of the firms along their growth stage based on the survey data of 2,515 Korean ventures. Venture characteristics include KSFs(Key Success Factors), environment attributes of their product markets, CEO roles, the use of OPR(Other Peoples Resource). Growth stage of the ventures are classified by their dominant management problems: foundation, the market launch of the first proprietary product or service, The Outset of second generation product or service, and the Initial Public Offering (IPO) and stabilization. The results of this study show substantial differences in many aspects among firms at different growth stages. Although common KSFs exist, KSFs are changing as the venture evolves. Differences in KSFs and environmental attributes along growth stage require CEO to do different role in business process. Different kinds and amounts of external resources are needed according to their growth stage. However, almost all of external resources are offered to ventures in later stage. Entrepreneurs need to change their role, as their firms grow, from visioning and strategic role to marketing and production emphasized role. Based on the results, this study suggests a number of new government policies and future research ideas. Other implications and limitations of this study are also noted.

Many concepts of external magnetic field applications in crystal growth processes have been developed to control melt convection, impurity content and growing interface shape. Especially, travelling magnetic fields (TMF) are of certain advantages. However, strong shielding effects appear when the TMF coils are placed outside the growth vessel. To achieve a solution of industrial relevance within the framework of the $KRISTMAG^{(R)}$ project inner heater-magnet modules(HMM) for simultaneous generation of temperature and magnetic field have been developed. At the same time, as the temperature is controlled as usual, e.g. by DC, the characteristics of the magnetic field can be adjusted via frequency, phase shift of the alternating current (AC) and by changing the amplitude via the AC/DC ratio. Global modelling and dummy measurements were used to optimize and validate the HMM configuration and process parameters. GaAs and Ge single crystals with improved parameters were grown in HMM-equipped industrial liquid encapsulated Czochralski (LEC) puller and commercial vertical gradient freeze (VGF) furnace, respectively. The vapour pressure controlled Czochralski (VCz) variant without boric oxide encapsulation was used to study the movement of floating particles by the TMF-driven vortices.

Photovoltaic (PV) systems are influenced by disproportionate impacts on energy production caused by frequent mismatch cases. The occurrence of multiple maximum power points (MPPs) adds complexity to the tracking process in various PV systems. However, current maximum-power point tracking (MPPT) techniques exhibit limited performance. This paper introduces an enhanced simulated annealing (ESA)-based GMPPT technique against multiple MPP issues in P-V curve with different PV system structures. The proposed technique not only distinguishes global and local MPPs but also performs rapid convergence speed and high tracking accuracy of irradiance changing and restart capability detection. Moreover, the proposed global maximum power tracking algorithm can be applied in the central converter of DMPPT and hybrid PV system to meet various application scenarios. Its effectiveness is verified by simulation and test results.

Indium tin oxide (ITO) is widely used to make a transparent conducting film for various display devices and opto-electric devices. In this study, ITO films on glass substrate were fabricated by inductively coupled plasma (ICP) assisted dc magnetron sputtering. A two-turn rf coil was inserted in the process chamber between the substrate and magnetron for the generation of ICP. The substrates were not heated intentionally. Subsequent post-annealing treatment for as-deposited ITO films was not performed. Low-temperature deposition technique is required for ITO films to be used with heat sensitive plastic substrates, such as the polycarbonate and acrylic substrates used in LCD devices. The surface roughness of the ITO films is also an important feature in the application of OLEDs along with the use of a low temperature deposition technique. In order to obtain optimum ITO thin film properties at low temperature, the depositions were carried out at different condition in changing of Ar and $O_2$ gas mixtures, ICP power. The electrical, optical and structural properties of the deposited films were characterized by four-point probe, UV/VIS spectrophotometer, atomic force microscopy(AFM) and x-ray diffraction (XRD). The electrical resistivity of the films was -l0$^{-4}$ $\Omega$cm and the optical transmittance in the visible range was ＞85%. The surface roughness ( $R_{rms}$) was -20$\AA$.>.

According to change a generation, in modern society the view which looks at the nature the people and the space is changing. As recognition which the environment is the most important factor in our society, there are researches that environment has to preserve and there are methods that the environment is related with the human, therefore, in the space ecology design views that similar to modern society are being shift. Museum of natural environment is public and popular space that it is designed and composed by a method of ecology space design. Hence, on this study, the museum of natural environment is defined public space by ways of characteristics of ecology design and a design characteristic which the museum of natural environment basically has to arrange are examined. Gallery of natural environment is most related with subsidiarity of mutuality, unity of the totality and stablity and will need other factors such as diversity & balance and suitability. Characteristic of museum of natural environment will be understood method for extension of a sustainable and mutual public space based on the this study, and it will become a process that we will have to advance for not only the present day but also the future.

Following the developing tendency of the food service industry, people are showing a high interest in cooking and the number of applicant trying to learn how to cook is increasing gradually. In this research, we have concluded that developing a menu, we are to standardize its cost accounting correctly so as to reduce problems which can occur during the process to commercialize food. We have to research on the quality of food changing so fast and to develop proper food to suit both the oriental and occidental taste. Since fresh ingredients such as olive oil which has much unsaturated fatty acid, tomato, and fish etc. is usually used in making Italian food, especially the moderns love it very much. The reason is that eating fatty food such as meat and fish with tomato, we can digest it well in our stomach. Tomato play an important role to neutralize the effects of acid food. It has Vitamin B1 dissolving fat, rutin strengthening capillary vessels and controlling high blood pressure, amino acid developing mental activity, iron essential to blood formation, and calcium etc. These ingredients play important roles to control geriatric diseases. The new style of the propensity to consume in the class of new generation and new family, the trend towards the nuclear family, and the rapid expansion of aging have influences on westernizing diet and on spreading new sense of values such as rapidness, convenience, cleanliness, and simplicity for diet. Following the change of the times, the food service industry will be developed more and more.

This dissertation is considered a historic generation that Chinese film $6^{th}$ director remembers through their life. Also it is figured out historic anguish and hurt how it was remembered and appeared in film. They have made actual films through their efforts which are different from the conventional generation. In addition, between memory and oblivion the time's signification in the history is showed how what way can be represented. It was presented the time's anguish through memory's metaphor in Chinese film $6^{th}$ works. Also, it was shown the existence's reality from dream was losing as memory was hiding between desire and despair. Additionally, the self of daily was expressed to unconcernedly accept reality, and its against the unchangeable world's eye and memory. The $6^{th}'s$ films' desire was expressed passive appearance to accept reality with losing dream in these three things; cannot be reality in the process to figure out own natural character, and appearance to keep traditional character, finally gradually changing reality. When $6^{th}$ directors analysis the history as memory, social repression follows family's repression, family's repression brings personal repression, and then repression changes to desire, finally the life as a reaction could be maintained. In conclusion, personal desire was covered for fantasy, and the overcoming figure was represented. Moreover, Chinese face that $6^{th}$ directors have memorized was presented through these sentiments.

Although the construction industry is changing from a 2D-based to a 3D BIM-based management process, 2D drawings are still used as standards for permits and construction. For this reason, 2D deliverables extracted from 3D BIM are one of the essential achievements of BIM projects. However, due to technical and institutional problems that exist in practice, the process of extracting 2D deliverables from BIM requires additional work beyond generating 3D BIM models. In addition, the consistency of data between 3D BIM models and 2D deliverables is low, which is a major factor hindering work productivity in practice. To solve this problem, it is necessary to build BIM data that meets information requirements (IRs) for extracting 2D deliverables to minimize the amount of work of users and maximize the utilization of BIM data. However, despite this, the additional work that occurs in the BIM process for drawing creation is still a burden on BIM users. To solve this problem, the purpose of this study is to increase the productivity of the BIM process by automating the process of extracting 2D deliverables from BIM and securing data consistency between the BIM model and 2D deliverables. For this, an expert interview was conducted, and the requirements for automation of the process of extracting 2D deliverables from BIM were analyzed. Based on the requirements, the types of drawings and drawing expression elements that require automation of drawing generation in the design development stage were derived. Finally, the method for developing automation technology targeting elements that require automation was classified and analyzed, and the process for automatically extracting BIM-based 2D deliverables through templates and rule-based automation modules were derived. At this time, the automation module was developed as an add-on to Revit software, a representative BIM authoring tool, and 120 rule-based automation rulesets, and the combinations of these rulesets were used to automatically generate 2D deliverables from BIM. Through this, it was possible to automatically create about 80% of drawing expression elements, and it was possible to simplify the user's work process compared to the existing work. Through the automation process proposed in this study, it is expected that the productivity of extracting 2D deliverables from BIM will increase, thereby increasing the practical value of BIM utilization.

Because of the temperature gradient occurring during the growth of the ingot with directional solidification method, defects are generated and the residual stress is produced in the ingot. Changing the growth and cooling rate during the crystal growth process will be helpful for us to understand the defects and residual stress generation. The defects and residual stress can affect the properties of wafer. Generally, it was found that the size of grains and twin boundaries are smaller at the top area than at the bottom of the ingot regardless of growth and cooling condition. In addition to that, in the top area of silicon ingot, higher density of dislocation is observed to be present than in the bottom area of the silicon ingot. This observation implies that higher stress is imposed to the top area due to the faster cooling of silicon ingot after solidification process. In the ingot with slower growth rate, dislocation density was reduced and the TTV (Total Thickness Variation), saw mark, warp, and bow of wafer became lower. Therefore, optimum growth condition will help us to obtain high quality silicon ingot with low defect density and low residual stress.
