Recently, The culture of accommodations have been developed and diversified as there have increasing people who want to enjoy in their extra-time. However, User's satisfaction have decreasing due to the accommodations have been focused on quantity and uniformed developing. Therefore, The accommodations are needed an accurate planning that it is regarded about the characteristic of an architecture and user's emotion without the purpose of benefit or the object of developing. So, It must be overwhelmed with the things of pleasure which the people have experience. Nowadays, The concerning of traditional accommodations as Hanok have increasing that it is engaged in the concerning of eco-friendly architecture, However, there is not much studies about this object. Consequently, the purpose of this study is presentation of basic materials for the traditional accommodations as Hanok throughout investigate that.

This paper proposes an adaptive routing protocol called ARCA for converged ad-hoc and cellular network (CACN). Due to the limitation of both bandwidth and transmission range in a cell, a mobile host (MH) may not be able to make a call during busy time. CACN offers a flexible traffic diversion mechanism that allows a MH to use the bandwidth in another cell to ease the congestion problem and increase the throughput in a cellular network. Based on the presentation of CACN's physical characteristics, the paper details the design issues and operation of the adaptive routing protocol for CACN (ARCA). Detailed numerical analysis is presented in terms of both route request rejection rate and routing overhead, which, along with the simulation results, have indicated the effectiveness and efficiency of the ARCA protocol.

The method of pinpointing the place of the abnormalities of a power transmission system analyzes the voltage and the current information from the both ends of a power [1-2]. Now, there are only current and a voltage measuring instrument every about 20km, and the present condition is specifying the breaking down point by viewing of a worker in it. In this research, a power line circuit is assumed to be a line type system, and M-sequence is impressed to the end, it receives at other ends, the crosscorrelation function of input and output is taken, an impulse response is calculated, and the method in comparison with the time of normal is proposed. By this technique ...

KIC6118779 is an over-contact binary system having a short orbital period of about 0.36 days. The photometric data for this system are acquired by the observations of Kepler mission in the long cadence mode having a time resolution of about 30 minutes. It means that the Kepler light curves of the system may be strongly affected by phase smearing effect and the analysis of them without consideration of the phase smearing effect may result in wrong stellar properties. Additionally, this system also shows dynamical variation of light curve resulting from spot activity. For all those reasons, it is difficult to investigate KIC6118779, and the investigation should be carried out carefully. In this presentation, we introduce the phase smearing effect and carry out the light curve modeling with the 2015 version of the Wilson-Devinney binary code considering the phase smearing effect. Our results show that the system is a deep over contact binary system and has extremely low mass ratio of about 0.12. Moreover our spot modeling implies the cyclic migration of a big cool spot on the massive component.

In this thesis presents line balancing problems of two-sided and mixed model assembly line widely used in practical fields using genetic algorithm for reducing throughput time, cost of tools and fixtures and improving flexibility of assembly lines. Two-sided and mixed model assembly line is a special type of production line where variety of product similar in product characteristics are assembled in both sides. This thesis proposes the genetic algorithm adequate to each step in tow-sided and mixed model assembly line with suitable presentation, individual, evaluation function, selection and genetic parameter. To confirm proposed genetic algorithm, we apply to increase the number of tasks in case study. And for evaluation the performance of proposed genetic algorithm, we compare to existing algorithm of one-sided and mixed model assembly line. The results show that the algorithm is outstanding in the problems with a larger number of stations or larger number of tasks.

To compare the quality of ultrastructural preservation of Scanning Electron Microscopic specimens dried with different methods; pure air-drying, air-drying with using Tetramethylsilane(TMS), four kind of air-drying using Hexamethyldisilazane(HMDS) and critical point drying(CPD), we conducted scanning electron microscopic observation on liver, skeletal muscle and intestinal tissues from laboratory rat treated with each method. In pure air drying group, severe distortion of tissue surface was observed, and in HMDS treated group, only liver tissue showed slight distortion. But in TMS treated group, each tissue showed a good presentation comparable to CPD group. The results suggest that the method of air-drying using TMS may be the former is less expensive and simple be and also time-saving.

Immune system is composed of multiple cells with distinct functions, and immune responses are orchestrated by complex and dynamic cell-cell interactions. Therefore, each cell behavior and function should be understood under right spatio-temporal context. Studying such complexity and dynamics has been challenging with conventional biological tools. Recent development of new technologies such as state of art imaging instruments and microfabrication techniques compatible with biological systems have provided many exciting opportunities to dissect complex and dynamic immune cell interactions; new microscopy techniques enable us to observe stunning dynamics of immune system in real time. Microfabrication permits us to manipulate microenvironments governing molecular/cellular dynamics of immune cells to study detailed mechanisms of phenomena observed by microscopy. Also, microfabrication can be used to engineer microenvironments optimal for specific imaging techniques. In this presentation, I am going to present an example of how these two techniques can be combined to tackle challenging problems in immunology. Obviously, this strategy can readily be applied to many different fields of biology other than immunology.

Purpose: This study was to explore gender differences on presenting patients with acute myocardial infarction in the emergency department. Methods: The survey was done with 143 emergency medical charts presented to the emergency department and diagnosed with acute myocardial infarction between January 2005 and December 2006. The collected data were analyzed with frequency, chi-square, and t-test. Results: Significant gender differences were apparent in age, route to the emergency department, elapsed time from onset of symptoms to arrival, and initial heart rate. Women were significantly more likely to report hypertension, diabetes, and congestive heart failure than men, but men were significantly more likely to report smoking. Chest pain was the most common initial symptom in both men and women. Women were significantly more likely to report dyspnea and nausea/vomiting than men. Conclusion: Although similarities exist in the associated symptoms of acute myocardial infarction, women might experience different symptoms, compared to men. These findings have implication that patients and health care providers should consider gender difference in presenting symptoms.

In the history of fashion, few designers have interpreted the background of the time more accurately and energetically than did Elsa Schiaparelli. She understood the new role of women and believed clothes should suit one's life style. Schiaparelli begun with sportswear, later included suits and dresses. She produced them of great elegance and extreme chic. Simplicity of line was the key to her distinctive and elegant silhouette. Even her simplest designs had elegance. Her concept of clothes was architectual : the more the plane of the body were respected, the more the garment acquired vitality. Schiaparelli combined her knowledge, timing, and sense of daring in the presentation of her designs, colors, fabrics, and embroideries. For V, the garment was not only the medium for the couturier's craft but also the place for artistic expression. Her self-conscious equation of designer's objectives with that of artist is at the heart of her work. Schiaparelli's work is an expression of desire, not merely of design.
