High blood pressure is main today's adult disease and existing blood pressure gauge is not possible for real-time blood pressure measurement and remote monitoring. But real-time blood pressure monitoring u-healthcare system makes effect health management. In my paper, for monitoring real-time blood pressure, an architecture of real-time blood pressure monitoring system which consisted of wrist type-blood pressure measurement, smart-phone and u-healthcare server is presented. And the analog circuit architecture which is major core function for pulse wave detection and digital hardware architecture for wrist type-blood pressure measurement is presented. Also for software development to operate this hardware system, UML analysis method and flowcharts and screen design for this software design are showed. Therefore such design method in my paper is expected to be useful for real-time blood pressure monitoring u-healthcare system implementation.

Purpose: The purpose of this study was to compare the proapoptotic effects of matrix metal-loproteinase inhibitor (MMPI) and doxorubicin on wild-type p53 osteosarcoma cell line, socalled U2OS cell line. Materials and Methods: U2OS cells were treated with MMP inhibitor III (MMPI III) and doxorubicin, either respectively or simultaneously. In cells treated with doxorubicin, Fas-neutralizing antibody so called ZB4 was additionally treated to examine whether the doxorubicin played a role through the Fas/FasL pathway. Cells were analysed regarding to apoptosis and cell death by flow cytometry. Results: U2OS cells incubated with doxorubicin showed significant amount of cell death in dose-dependent manner. However, those incubated with MMPI III mostly remained viable state. In addition, there is no relationship between two drugs. Cells treated with doxorubicin and ZB4 at the same time did not show down regulation of apoptosis through inhibition of Fas/FasL pathway. Conclusion: It is important to re-examine MMP inhibitor's effect on other osteosarcoma cell line with wild-type p14 as well as wild-type p53 to evaluate its proapoptotic effect.

To investigae the effect of anchorage type of carbon fiber sheet (CFS) on flexural behavior of RC beams, the loading test of RC beams reinforced with CFS was conducted in variable of anchorage Type such as bolting anchorage and U type anchorage using CFS. This study can be summarized as follows ; It is confirmed experimentally that the bolting anchorage and U type anchorage with CFS is very effective to delay the bond failure and prevent the peeling of CFS. Also, the anchorage type applied with this study is very effective to improve the ductility compared with the improving of maximum flexural strength of RC beams. It is believed that the anchorage type used this study must secure the ductile capacity of above 3 for the flexural strengthening of RC beams. In the future, it is required to obtain the data about anchorage type of CFS for utilization of field work as well as investigate the ductile capacity of conventional study of anchorage type

Purpose: The purpose of this study was to identify the influence of interpersonal attitude (I+, I-, U+, U-) on communication competence in care workers for frail elderly. Methods: This study was a cross-sectional survey. The data were collected from 153 care workers for frail elderly using a structured questionnaire. The data were analyzed using multiple regression with the SPSS/WIN 20.0 program. Results: The interpersonal attitude style of subjects was I+U+, and the score of communication competence was 3.53. There were significant differences in interpersonal attitude (I+, I-), and communication competence depending on age, education level, experience of personality type test (yes). Factors influencing on communication competence in care workers were interpersonal attitude (I+, I-, U+) and experience of personality type test with $R^2$ value of 48.5% (F=23.47 p<.001). The most influencing factor was I+ (${\beta}$=.36), followed by I- (${\beta}$=-.22), U+ (${\beta}$=.20), and experience of personality type test (yes) (${\beta}$=.16). Conclusion: It is needed to maintain the interpersonal attitude style (I+U+) of care workers. Continuing education program is needed for increasing communication competence especially for those fifties and over, and experienced care workers. Giving an opportunity for personality test is helpful to increase communication competence in care workers.

Botulinum toxin-A, a neurotoxin derived from Clostridia Botulinum, has been injected into the laryngeal muscle(s) for the treatment of the spasmodic dysphonia at the Voice Clinic, Yonsei Institute of Logopedics and phoniatrics since December 1995. We analyzed 355 patients with spasmodic dysphonia, using Botox register review. In the 355 patients, female is 86.8%. male is 13.2%. 305 patients (85.9%) had adductor type of spasmodic dysphonia and 35 patients (9.9%) were vocal tremor type and 15 patients were abduction and mixed type. Botulinum toxin type-A (Botox) injection using EMG was most frequently conducted as 587 cases, comparing with flexible nasopharyngoscopy gudied injection (68cases) and tele- laryn-goscopy guided injection (31cases). In the respect of frequency of Botox injection, 137 patients(38.6%) were injected one time but 1 patient was injected 17times. The mean dose of Botox is 6.2U. Clinically, initial dose of Botulinum toxin-A was high dose (7-8U) but current dose is small dose (3U). And the mean duration of Botox injection is 6.4 month. In conclusion, to optimize effect of the treatment for spasmodic dysphonia, Botulinum toxin-A injection is combined with voice therapy.

The flagella antigenic variation of nine Bacillus thuringiensis serovar kurstaki temperature-sensitive mutants grown at the permissive temperature (3$0^{\circ}C$) was detected by a serological agglutination between H-antigen and antiserum. The flagella antigens were injected to rabbits to prepared their antisera, and then their homologous and heterologous titers of the antisera were measured. The homologous titers were ranged from 1:6,400 to 1:12,800, but the heterologous titers were very low. The H-antigen of the wild type strain was not agglutinated to 4 heterologous antisera, ts-U23 not to 7, ts-U3l not 5, ts-U32 not to 4, ts-U33 not to 7, ts-U7l not to 4, ts-U73 not to 6, ts-U74 not to 6, ts-U91 not to 4 and ts-U603 not to 4 antisera.

In this paper, we study the method of upper and lower solutions and develop the generalized quasilinearization technique for the existence and approximation of solutions to some three-point nonlocal boundary value problems associated with higher order fractional differential equations of the type $$^c{\mathcal{D}}^q_{0+}u(t)+f(t,u(t))=0,\;t{\in}(0,1)$$ $$u^{\prime}(0)={\gamma}u^{\prime}({\eta}),\;u^{\prime\prime}(0)=0,\;u^{\prime\prime\prime}(0)=0,{\ldots},u^{(n-1)}(0)=0,\;u(1)={\delta}u({\eta})$$, where, n-1 < q < n, $n({\geq}3){\in}\mathbb{N}$, 0 < ${\eta},{\gamma},{\delta}$ < 1 and $^c\mathcal{D}^q_{0+}$ is the Caputo fractional derivative of order q. The nonlinear function f is assumed to be continuous.

We study the asymptotic behavior of nonnegative singular solutions of semilinear parabolic equations of the type $$u_t={\Delta}u-(u^q)_y-u^p$$ defined in the whole space $x=(x,y){\in}R^{N-1}{\times}R$ for t>0, with initial data a Dirac mass, ${\delta}(x)$. The exponents q, p satisfy $$1 where $q^*=max\{q,(N+1)/N\}$.

In this paper we will consider the weighted composition operator $W=uC_{\varphi}$ between two different $L^p(X,\;\Sigma,\;\mu)$ spaces, generated by measurable and non-singular transformations $\varphi$ from X into itself and measurable functions u on X. We characterize the functions u and transformations $\varphi$ that induce weighted composition operators between $L^p-spaces$ by using some properties of conditional expectation operator, pair $(u,\;\varphi)$ and the measure space $(X,\;\Sigma,\;\mu)$. Also, Fredholmness of these type operators will be investigated.

In a bounded domain, we consider $$u_{tt}-{\Delta}u+{\normalsize\displaystyle\smashmargin{2}{\int\nolimits_0}^t}\;g(t-{\tau}){\Delta}ud{\tau}+u_t={\mid}u{\mid}^pu$$, where p > 0 and g is a nonnegative and decaying function. We establish a general decay result which is not necessarily of exponential or polynomial type.
