Purpose: The purpose of this study was to compare the needs of case management between Medical aid beneficiaries with simple and multiple chronic diseases (SCD vs MCD). Methods: The study employed secondary analysis method using a cross-sectional data from 2009 case management service enrollees. Data on 35,862 beneficiaries who have chronic disease(s) were used in the description of chronic disease characteristics, and data on 20,392 beneficiaries, excluding those who have depression and/or disabilities, were used to compare the group differences. Results: Mean age was $68.8{\pm}11.63years$, and 73.3% were females. MCD group showed an older age, had more women than SCD group. Self-care ability and appropriateness of health care utilization were significantly different between the groups, but there was no difference in health-related quality of life. In subscales, there were significant differences in general health status, depression, symptom management, healthy lifestyle, hygiene and vaccination, and appropriateness of health utilization. Conclusion: Different characteristics between patients with simple and multiple chronic diseases indicate that different case management approaches are required for these groups. The study results could be used as a basis for the development of case management model tailored to the characteristics and needs of medical-aid beneficiaries.

Silicon nano-structures have great potential in bionic sensor applications. Atomic force microscopy (AFM) anodic oxidation have many advantages for the nanostructure fabrication, such as simple process in atmosphere at room temperature, compatibility with conventional Si process. In this work, we fabricated simple FET structures with channel width W~ 10nm (nanowire) and $1{\mu}m$ (nano-ribbon) on ~10, 20 and 100nm-thinned silicon-on-insulator (SOI) wafers in order to investigate the surface effect on the transport characteristics of nano-channel. For further quantitative analysis, we carried out the 2D numerical simulations to investigate the effect of channel surface states on the carrier distribution behavior inside the channel. The simulated 2D cross-sectional structures of fabricated devices had channel heights of H ~ 10, 20, and 100nm, widths of L ~ $1{\mu}m$ and 10nm respectively, where we simultaneously varied the channel surface charge density from $1{\times}10^{-9}$ to $1{\times}10^{-7}C/cm2$. It has been shown that the side-wall charge of nanowire channel mainly affect the I-V characteristics and this was confirmed by the 2D numerical simulations.

Spatial structures have the different dynamic characteristics from general rahmen structures. Therefore, it is necessary to accurately analyze dynamic characteristics and seismic response of spatial structure for seismic design of spatial structure. An arch structure is used as an example structure because it has primary characteristics of spatial structures. Multiple support excitation may be subjected to supports of a spatial structure because ground condition of spatial structures is different. In this study, the response analysis of the arch structure under multiple support excitation and simple support excitation is studied. By means of the pseudo excitation method, the seismic response is analyzed for long span spatial structure. It shows that the structural response is divided into two parts, ground displacement and structural dynamic response due to ground motion excitation. It is known that the seismic response of spatial structure under multiple support excitation and simple support excitation are the different in some case. Therefore, it has to be necessary to analyze the seismic response of spatial structure under multiple support excitation because the spatial structure supports may be different.

The boiling heat transfer characteristics of two-phase closed thermosyphons with internal grooves are studied experimentally and a simple mathematical model is developed to predict the performance of such thermosyphons. The study focuses on the boiling heat transfer characteristics of a two-phase closed thermosyphons with copper tubes having 50, 60, 70, 80, 90 internal grooves. A two-phase closed thermosyphon with plain copper tube having the same inner and outer diameter as those of grooved tube is also tested for comparison. Methanol is used as working fluid. The effects of the number of grooves, the operating temperature, the heat flux are investigated experimentally. From these experimental results, a simple mathematical model is developed. In the present model, boiling of liquid pool in the evaporator is considered for the heat transfer mechanism of the thermosyphon. And also the effects of the number of grooves, the operating temperature, the heat flux are brought into consideration. A good agreement between the boiling heat transfer coefficient of the thermosyphon estimated from experimental results and the predictions from the present mathematical model is obtained. The experimental results show that the number of grooves and the amount of the working fluid are very important factors for the operation of thermosyphons. The two-phase closed thermosyphon with copper tubes having 60 internal grooves shows the best boiling heat transfer performance.

Different from general operating policies applied for various waiting line situations, two complementary dyadic operating policies are applied alternatingly to a single server maintenance service center model. That is, either of the two dyadic Min (N, T) or Max (N, T) policy is applied to operate such center first and the other operating policy should be applied later, and then the same sequence of both operating policies is followed repeatedly. This operating policy is denoted by the Minimax (N, T) policy. Purpose: Because of the newly introduced operating policy, important system characteristics of the considered service center model such as the expected busy and idle periods, the expected number of customers in the service center and so on should be derived to provide necessary information for determination of the optimal operating policy. Methods: Based on concepts of the newly introduced Minimax (N, T) policy, all necessary system characteristics should be redefined and then derived by constructing appropriate relations between complementary two dyadic operating policies. Results: Desired system characteristics are obtained successfully using simple procedures developed by utilizing peculiar structure of the Minimax (N, T) policy. Conclusion: Applying Minimax (N, T) operating policy is equivalent to applying the simple N and T operating policies alternatingly.

The theoretical bases on characteristics of heat release rate in compartment of building for scenario of smoke management are introduced and the numerical applications to simple compartment model are carried out. The growth stage which is important for smoke management design is modelled as t-squared fire curve including fire growth coefficient with related to growth rate. The conditions for the happening of flashover is presented such as $600^{\circ}C$ of temperature or $20kW/m^2$ of radiation heat flux. After the flashover happen, the fire in compartment changes to fully developed fire having the characteristics of ventilation-controlled fire. As the result of numerical analysis to simple compartment model, the time to reach 900K under ceiling for condition of medium growth is twice for condition of fast growth.

Futurists put forward creative fashion by combining art and functionality. This led to a new aesthetic approach in how we view modernized industrial cities. Ernesto Thayaht, a futurist, introduced the "Tuta", which was simple and practical clothes. Tuta expressed the imagination and aesthetic values of Futurism. The characteristics of the Tuta were categorized into the following: Form, Colors, Materials, and Details. The results of examining its characteristics as follows: Tuta had a linear and simple planar pattern, which could be made with one cloth. The same modernized urban colors were used for the top and the bottom. Practical Materials, such as cotton and linen were used because they were easy to wash. Tuta excluded unnecessary ornaments, and only included functional details that would allow for comfortable movement. These design characteristics of Tuta revealed functionality, popularity, modernity, and innovativeness of formativeness. Tuta presented a new model of fashion in the early 20th century and completed the modernization of clothes. Tuta reflected the democratic and equal spirit of the era by innovating and overcoming the structure and form of conventional clothing.
