Physicians, in order to study the causes of cancer, detect cancer earlier, prevent or determine the effectiveness of treatment, and specify the reasons for the treatment ineffectiveness, need to access accurate, comprehensive, and timely cancer data. The cancer care environment has become more complex because of the need for coordination and communication among health care professionals with different skills in a variety of roles and the existence of large amounts of data with various formats. The goals of health care systems in such a complex environment are correct health data management, providing appropriate information needs of users to enhance the integrity and quality of health care, timely access to accurate information and reducing medical errors. These roles in new systems with use of agents efficiently perform well. Because of the potential capability of agent systems to solve complex and dynamic health problems, health care system, in order to gain full advantage of E- health, steps must be taken to make use of this technology. Multi-agent systems have effective roles in health service quality improvement especially in telemedicine, emergency situations and management of chronic diseases such as cancer. In the design and implementation of agent based systems, planning items such as information confidentiality and privacy, architecture, communication standards, ethical and legal aspects, identification opportunities and barriers should be considered. It should be noted that usage of agent systems only with a technical view is associated with many problems such as lack of user acceptance. The aim of this commentary is to survey applications, opportunities and barriers of this new artificial intelligence tool for cancer care information as an approach to improve cancer care management.

With speeding up the process of being international municipality, the gravity of lacking parking lots in Shanghai urban area, which directly blocks the traffic in the city, has been revealed. This thesis analyses present automobiles parking capability and forecasts the future's needs for the city. To solve the problem, the concept could be to expand parking areas in city center recently to relax the tention and to do thoughtful planning in the near future on the foundation of fully consideration the trend. The municipal government has to set up policy properly, amplify regulations, strenthern the administration and open up a path to raise founds. Berween road system administration which is dynamic and parking lot system administration which is static, there are a knot on macroscopic meaning and an interference as well. The coordination of these two systems would be reflested on the effects of whole municipal traffic adminisration. Basically, public parking lots are city's foundal facilities, just like roads, bridges, etc. The main problems now in Shanghai are large parking space demands, insufficient facilities, cheap parking expenses comparing with the cost of parking lots construcion and poor administration. According to the forecast on social economy development, there will be 580 thousand automobiles in Shanghai by the year 2000, and the amount of private cars will increase greatly. The frequency of automobiles going out will be 1.45 million per day. Public parking lots being able to afford 105 thousand units are needed. To satisfy the demands, the recent aim of planning should be speed up the parking lots construction, the planning objective in next period should be developing reasonably and exceed the demands properly. In order to realize the planning objective, the government has to formulate correct policy and amplify administration regulations. The government has to adopt both administration and economy means, including charging parking people reasonably, collect necessary taxes, bringing the parking lots planning into general municipality planning, opening up an effective path to raise founds, such as set up founds for parking lots construction, issue bonds and stocks, get loans at home and abroad, etc.

This study attempts to find out the characteristics of digital currency and currency transformation through the analytical descriptions of the literature. In the early days of the emergence of new currency, market-oriented autonomous monetary adjustment was made along with various attempts by the private sector, and then government-centered central currency management and coordination were made for the national monopoly of profits and power. Digital currency can be seen as the emergence of a new form of money that will bring about paradigm changes. CBDC can be divided into direct and indirect types. CBDC is expected to require a strategic approach by the government or firm as it will bring about changes in the ecosystem of related industries. Libra is a stablecoin designed to minimize price fluctuations, and if it succeeds in commercializing it, it is expected to bring about revolutionary changes in the financial industry around the world.

Purpose : The purposes of this study were to find correlations among Fugl-Meyer Assessment Scale, walking velocity, walking asymmetry and balance ability. Methods : The study sample consisted of 50 stroke patients referred to the Department of Rehabilitation Medicine in the Sanggye Paik, Ilsan Paik, Seoul Paik, and Dobong Hospital. All subjects were ambulatory with or without an assistive device. All participants were assessed on Fugl-Meyer Assessment scale and walking velocity, walking asymmetry. The data were analyzed using independent t-test, ANOVA, and multiple regression. Results : The results revealed that upper extremity coordination, balance and pain items of Fugl-Meyer Assessment scale were significantly correlated with walking velocity and upper extremity and upper extremity motor and balance items of Fugl-Meyer Assessment scale were significantly correlated with walking asymmetry. Fugl-Meyer Assessment scale was not significantly correlated with Static Balance Index, Dynamic Balance Index and Weight Distribution Asymmetry Index. Their power of explanation regarding comfortable walking velocity and comfortable walking asymmetry were 60.3%, 42.5% respectively. Conclusion : These results showed that Fugl-Meyer Assessment scale is significantly correlated with walking velocity, asymmetry and not significantly correlated with balance ability. Therefore Fugl-Meyer Assessment scale is an appropriate assessment tool to predict walking ability of patients with stroke. Futher study about walking velocity and asymmetry by change of Fugl-Meyer Assessment scale is needed using a longitudinal study design.

This paper presents simulation and small-scale experimental tests of a fault current controller. Smart fault controller as proposed and proven conceptually in our previous work is promising technology for the smart power grid where distributed and even stochastic generation sources are prevalent and grid operations are more dynamic. Existing protection schemes simply limiting the fault current to the pre-determined set values may not show best performance and even lead to coordination failures, potentially leading to catastrophic failure. Thus, this paper designs fault current controller with a full bridge thyristor rectifier, embedding a superconducting coil for which the controller is electrically invisible during normal operation because the loss due to the coil is near-zero. When a fault occurs and the resulting current through the superconducting coil exceeds a certain value set intelligently based on the current operating condition of the grid, the magnitude of the fault current is controlled to this desired value by adjusting the firing angles of thyristors such that the overall system integrity is successfully maintained. Detailed time-domain simulations are performed and lab-scale testing circuits are built to demonstrate the desired functionality and efficacy of the proposed fault current controller.

This paper deals with a powerful countermeasure for power quality problems caused by the operation of electrical arc furnace in bulk power systems. The rapid active load fluctuations of electrical arc furnace could produce several problems such as voltage flicker and active power oscillations. The typical methods using only the reactive power compensation have their own limitation in solving the power quality problems caused by active load variations. The coordination of both active and reactive power compensation is required to solve the power quality problems. This paper focuses on the impacts and the dynamic phenomena caused by the active load fluctuation. This paper proposes the optimal algorithm for the active power compensation based on the function of 1(n ratio and the concepts for the active power compensation. The results from a case study show that the proposed methods can be a practical tool for the power quality problems in power systems.

In a tactical-edge environment, where multiple weapon resources are coordinated together via services, it is essential to make an efficient binding between an abstract service and a resource that are needed to execute composite services for accomplishing a given mission. However, the tactical network that is used in military operation has low bandwidth and a high rate of packet loss. Therefore, communication overhead between services must be minimized to execute composite services in a stable manner in the tactical network. In addition, a tactical-edge environment changes dynamically, and it affects the connectivity and bandwidth of the tactical network. To deal with these characteristics of the tactical network we propose two service-resource reallocation methods which minimize the communication overhead between service gateways and effectively manage neutralization of gateways during distributed service coordination. We compared the effectiveness of these two - methods in terms of total communication overhead between service gateways and resource-allocation similarity between the initial resource allocation and the reallocation result.

Purpose: The purposes of this study were to develop the Korean version of the trunk impairment scale (K-TIS) and to examine reliability and responsiveness of the K-TIS in patients with stroke. Methods Subjects of the study were 51 stroke patients (mean age: 57.78 years) recruited from two stroke clinics. For the interrater and test-retest reliability, two raters measured the K-TIS two times using video clips with an interval of 2 weeks. For the responsiveness, intensive physical therapy training was provided to all participants 2 times a day for one month or three months depending on the onset of the stroke and the admission rules of the two clinics. Inter-rater reliability and test-retest reliability of the K-TIS three subscales (static sitting balance, dynamic sitting balance, and coordination) scores and total scores were examined using intra-correlation coefficient ($ICC_{3,1}$) and Pearson's correlation coefficient (r). To examine responsiveness, the minimally important difference (MID) was calculated with effect size. Results: Inter-rater reliability of the K-TIS subscales and total scores were all high (ICC3,1=0.920-0.983 and r=0.924-0.984). For the test-retest reliability, $ICC_{3,1}$=0.805-0.901 and r=0.806-0.903, and the MID for acute and post-acute as well as chronic stroke patients remained in the mean change range. Conclusion: It is suggested that the K-TIS might be used for clinical and research purposes as a standardized tool for stroke patients. In addition, it can also be useful in establishment of treatment goal(s) and planning treatment program(s) for patients with stroke.

In this study, we tried to scrutinize the status and problems of domestic cosmetics industry. On the basis of theoretical study, we examined the strategic marketing skill and tactics of foreign products to devise a strategy for domestic cosmetics with the help of marketing mix of foreign competitors: so to say 4 Ps. The core of the empirical research is hereby the effect of consumers' behavior. The conclusion of the research can be summarized as following: the most important problem of domestic cosmetics industry is the poor brand power. It has been confirmed that the consumer needs are various and dynamic. Analysis of 4 Ps of marketing factors of foreign goods shows this very clearly. Consumers tend to rely upon the brand name of the product rather than the quality, when they don't have enough information or knowledge on the product. This conclusion teaches us to make an effective strategy of marketing. It is brand power and brand cultivating. This study may give domestic marketers a motive to predict the future and succeed in existence and prosperity.

This study examined the synthesis of the crystal structure of bis(2,2'-bipyridine)nitrato zinc (II) nitrate, $[Zn(bipy)_2(NO_3)]^+NO_3^-$ using a microwave treatment at 300 W and 60 Hz for the application to dye-sensitized solar cells. The simulated complex structure of the complex was optimized with the density functional theory calculations for the UV-vis spectrum of the ground state using Gaussian 03 at the B3LYP/LANL2DZ level. The structure of the acquired complex was expected a penta-coordination with four nitrogen atoms of bipyridine and the oxygen bond of the $NO_3^-$ ion. The reflectance UV-vis absorption spectra exhibited two absorptions (L-L transfers) that were assigned to the transfers from the ligand ($\sigma$, $\pi$) of $NO_3$ to the ligand ($\sigma^*$, $\pi^*$) of pyridine at around 200 - 350 nm, and from the non-bonding orbital (n) of O in $NO_3$ to the p-orbital of pyridine at around 450 - 550 nm, respectively. The photoelectric efficiency was approximately 0.397% in the dye-sensitized solar cells with the nanometer-sized $TiO_2$ at an open-circuit voltage (Voc) of 0.39 V, a short-circuit current density (Jsc) of $1.79\;mA/cm^2$, and an incident light intensity of $100\;mW/cm^2$.
