In this paper, concerning the various advertising and policy advertising of the election with respect to whether to deliver a message to a large number of people, we design and implement an automative system what enables sending the text messages directly from the server to the client and also fast feedback is enabled by utilizing a number of operational programs to connect to the server. Therefore, we design and implement the automative communication system which enables delivering message to each user mobile terminal from a plurality of relay mobile terminals by utilizing the mobile instant messenger, not to deliver a message from the server to the mobile instant messenger user directly. In result of comparative analysis on the number of times of data transmission, this automative communication system utilizing mobile instant messenger shows the result that it enables transmitting five times per minute as it can copy and paste in the automation system regardless of the size of the data loading, otherwise in case of transmitting manually it show the result that the number of times of data transmission is reduced if the size of the data is larger.

The goal of medicine is to contribute to promoting national health by preventing diseases and providing treatment. The scope of modern medicine isn't merely confined to disease testing, treatment and prevention in accordance to that, and making experiments by using the human body is widespread. The advance in modern medicine has made a great contribution to valuing human dignity and actualizing a manly life, but there is a problem that has still nagged modern medicine: treatment and healing for terminal patients including cancer patients. In advanced countries, pain care and hospice medicine are already universal. Offering a helping hand for terminal patients to lead a less painful and more manly life from diverse angles instead of merely focusing on treatment is called the very hospice medicine. That is a comprehensive package of medical services to take care of death-facing terminal patients and their families with affection. That is providing physical, mental and social support for the patients to pass away in peace after living a dignified and decent life, and that is comforting their bereaved families. The National Hospice Organization of the United States provides terminal patients and their families with sustained hospital care and home care in a move to lend assistance to them. In our country, however, tertiary medical institutions simply provide medical care for terminal patients to extend their lives, and there are few institutional efforts to help them. Hospice medicine is offered mostly in our country by non- professionals including doctors, nurses, social workers, pastors or physical therapists. Terminal patients' needs cannot be satisfied in the same manner as those of other patients, and it's needed to take a different approach to their treatment as well. Nevertheless, the focus of medical care is still placed on treatment only, which should be taken seriously. Ministry for Health, Welfare & Family Affairs and Health Insurance Review & Assessment Service held a public hearing on May 21, 2008, on the cost of hospice care, quality control and demonstration project to gather extensive opinions from the academic community, experts and consumer groups to draw up plans about manpower supply, facilities and demonstration project, but the institutions are not going to work on hospice education, securement of facilities and relevant legislation. In 2002, Ministry for Health, Welfare & Family Affairs made an official announcement to introduce a hospice nurse system to nurture nurse specialists in this area. That ministry legislated for the qualifications of advanced nurse practitioner and a hospice nurse system(Article 24 and 2 in Enforcement Regulations for the Medical Law), but few specific plans are under way to carry out the regulations. It's well known that the medical law defines a nurse as a professional health care worker, and there is a move to draw a line between the responsibilities of doctors and those of nurses in association with medical errors. Specifically, the roles of professional hospice are increasingly expected to be accentuated in conjunction with treatment for terminal patients, and it seems that delving into possible problems with the job performance of nurses and coming up with workable countermeasures are what scholars of conscience should do in an effort to contribute to the development of medicine and the realization of a dignified and manly life.

This paper proposes new series and parallel Sin+Cos PSS(power system stabilizer) for the purpose to improve the existing PSS1A's performance. The purpose of PSS is used to enhance damping of power system oscillations through injection of auxiliary signal for an excitation control terminal. The Proposed series and Parallel Sin+Cos PSS is connected adding the Sin+Cos terms additionally with serial and with parallel connection in a conventional PSS1A. The proposed controller is aim to considering of a damping of oscillation when it changes parameter fluctuations or operational load variations in a power system. The object of electric power system is KEPCO system and the voltage of power transmission line is a 154kV and a 345kV. The PSCAD/EMTDC package is used to authorize the effect of the proposed controller. Simulations were shown by and compared with the waveforms for frequency, voltage and electric power.

The large AC generator fault may lead to large impacts or perturbations in power system. The generator protection control systems in Korea have been imported and operated through a turn-key from overseas entirely. Therefore a study of the generator protection field has in urgent need for a stable operation of the imported goods. In present, the algorithm using the current ratio differential relaying based DFT for stator winding protection or a fault detection had been applied that of internal fault protection of a generator. the DFT used for the analysis of transient state signal conventionally had defects losing a time information in the course of transforming a target signal to frequency domain. In this paper, the discrete wavelet transform (DWT) was applied a fault detection of the generator being superior to a transient state signal analysis and being easy to real time realization. The fault signals after executing a terminal fault modeling collect using a MATLAB package, and calculate the wavelet coefficients through the process of a muiti-level decomposition (MLD). The proposed algorithm for a fault detection using the Daubechies WT (wavelet transform) was executed with a C language and the commend line function for the real time realization after analyzing MATLAB's graphical interface. The advanced technique had improved faster a speed of fault discrimination than a conventional DFR based on DFT.

The CCAAT/enhancer-binding protein-alpha (CEBPA) is a transcriptional factor that plays a crucial role in the control of proliferation and differentiation of myeloid precursors. This gene was recognized as the target of genetic alterations and were associated with clinical complexity among AML. We here analyze the frequency and types of CEBPA mutations and polymorphisms in a de novo AML patients from South India and tried to find out associations of these variations with different clinical parameters and the prognostic significance in AML. Study was carried out in 248 de novo AML patients, cytogenetic analysis was performed from the bone marrow samples and was karyotyped. PCR-SSCP analysis and sequencing was performed for the detection of CEBPA gene variations. All the statistical analysis was performed using SPSS 17 (statistical package for social sciences) software. Pearson Chi-square test, Mann-Whitney U test, Kaplan-Meier survival analysis and log rank tests were performed. CEBPA mutations were detected in 18% and CEBPA polymorphisms were detected in 18.9% of AML cases studied. Most of the mutations occured at the C terminal region. Polymorphisms were detected in both N and C terminal region. with most common being, c.584_589dup ACCCGC and c.690G>T. A significant association was not observed for the mutation and polymorphism with respect to clinical and laboratory parameters. Survival advantage was observed for the mutated cases compared to non mutated cases, especially for the normal karyotype groups. Polymorphisms has no effect on the survival pattern of AML patients. CEBPA mutation and polymorphisms were observed with similar frequency and was identified in all the FAB subtypes as well as in cytogenetic risk groups in our study population, but CEBPA mutations alone confer a prognostic value for NK AML patients.
