  • Let (${\Omega}$, $\mathcal{S}$, ${\mu}$) be a probabilistic measure space, ${\varepsilon}{\in}\mathbb{R}$, ${\delta}{\geq}0$, p > 0 be given numbers and let $P{\subset}\mathbb{R}$ be an open interval. We consider a class of functions $f:P{\rightarrow}\mathbb{R}$, satisfying the inequality $$f(EX){\leq}E(f{\circ}X)+{\varepsilon}E({\mid}X-EX{\mid}^p)+{\delta}$$ for each $\mathcal{S}$-measurable simple function $X:{\Omega}{\rightarrow}P$. We show that if additionally the set of values of ${\mu}$ is equal to [0, 1] then $f:P{\rightarrow}\mathbb{R}$ satisfies the above condition if and only if $$f(tx+(1-t)y){\leq}tf(x)+(1-t)f(y)+{\varepsilon}[(1-t)^pt+t^p(1-t)]{\mid}x-y{\mid}^p+{\delta}$$ for $x,y{\in}P$, $t{\in}[0,1]$. We also prove some basic properties of such functions, e.g. the existence of subdifferentials, Hermite-Hadamard inequality.

  • Purpose: The purpose of this study was to examine the effect of Nei-Guan acupressure on nausea, vomiting, and anorexia in gynecological cancer patients receiving chemotherapy. Methods: Subjects consisted of 40 patients with cancer who were hospitalized and had chemotherapy at a general hospital located in Gyeonggi province, Korea. Control subjects (n=20) received only chemotherapy and intervention subjects (n=20) received Nei-Guan acupressure during their chemotherapy. The data were collected from February to October in 2008. Nausea and vomiting were measured with the Rhode's Index of Nausea, Vomiting, and Retching, and anorexia was measured using a Visual Analog Scale. Data were analyzed by X$^2$-test, t-test, repeated measures ANOVA. Results: Severity of nausea and vomiting in the intervention group was significantly less than in the control group. Repeated measure ANOVA revealed significant group effect (F=28.09, p=.000), time effect (F=321.48, p=.000), and interaction effect (F=7.90, p=.000). Severity of anorexia in the intervention group was significantly less than in the control group. Repeated measure ANOVA revealed significant group effect (F=28.68, p=.000), time effect (F=52.32, p=.000), and interaction effect (F=6.35, p=.000). Conclusions: Acupressure can be applied as a supportive nursing intervention to relieve nausea, vomiting, and anorexia in patients receiving chemotherapy.

  • The purpose of this study is to determine the effect of aromatherapy, showing how the composition handling of aromatherapy and abdominal massage treatment reaches body ingredient transformation. The subjects for this research were total 18 middle-aged females in Seoul; aroma massage group of 7 females, aroma inhalation and water bathe group of 5 females, abdominal massage group of 6 females by jojoba oil without any medical effect. This clinic trial was held from July 1, 2008 to Aug.14, 2008. I held this clinic trial under the same condition after and before this clinic. A standard tape and OLYMPIA 3.5 of S hospital were used at the body measuring for subjects after and before clinic trials. I got Average and standard deviation by data analysis by SPSS Win. Ver.14.0. I did paired t-test for the comparison of before and after, and repeated measure ANOVA for between two groups or among three groups'. The verification was held Duncan Test. The results of this study were as follows: 1. Body mass quotient (F=2.86, p= .063) and Body region (F=1.34, p= .279) among three groups showed no meaningful difference, but weight meaningful difference and aroma massage group showed the greatest difference of body measure change quantity. 2. In change quantity of abdomen girth, Waist circumference and WHR, abdomen girth (F=4.56, p= .012) and Waist circumference (F=4.37, p= .031) showed a meaningful statistical difference. The result of subsequent inspection showed that there was a meaningful difference among three groups and aroma massage group was best. 3. In Cell quantity, Body region quantity and Muscle volume, Body region quantity (F=2.76, p= .182) and Muscle volume (F=3.12, p= .054) showed no difference, but Cell quantity (F=3.79, p= .040) showed a meaningful difference. In the comparison of three groups there was no difference, but aromatherapy group showed more change quantity than any other group. According to the result of this study, the composition handling of aromatherapy and body massage was effective in the decrease of Abdominal fatness and Waist circumference, Weight and the increase of Cell quantity. so I suggest that woman use this therapy in the program of obesity management for her health improvement.

  • Let G be a non-discrete locally compact abelian group, and 𝜇 be a transformable and translation bounded Radon measure on G. In this paper, we construct a Segal algebra S𝜇(G) in L1(G) such that the generalized Poisson summation formula for 𝜇 holds for all f ∈ S𝜇(G), for all x ∈ G. For the definitions of transformable and translation bounded Radon measures and the generalized Poisson summation formula, we refer to L. Argabright and J. Gil de Lamadrid's monograph in 1974.

  • For 0 < $p$ < ${\infty}$, ${\alpha}$ > -1 and 0 < $r$ < 1, we show that if $f$ is in the space of Dirichlet type $\mathfrak{D}^p_{p-1}$, then ${\int}_{1}^{0}M_{p}^{p}(r,f^{\prime})(1-r)^{p-1}rdr$ < ${\infty}$ and ${\int}_{1}^{0}M_{(2+{\alpha})p}^{(2+{\alpha})p}(r,f^{\prime})(1-r)^{(2+{\alpha})p+{\alpha}}rdr$ < ${\infty}$ where $M_p(r,f)=\[\frac{1}{2{\pi}}{\int}_{0}^{2{\pi}}{\mid}f(re^{it}){\mid}^pdt\]^{1/p}$. For 1 < $p$ < $q$ < ${\infty}$ and ${\alpha}+1$ < $p$, we show that if there exists some positive constant $c$ such that ${\parallel}f{\parallel}_{L^{q(d{\mu})}}{\leq}c{\parallel}f{\parallel}_{\mathfrak{D}^p_{\alpha}}$ for all $f{\in}\mathfrak{D}^p_{\alpha}$, then ${\parallel}f{\parallel}_{L^{q(d{\mu})}}{\leq}c{\parallel}f{\parallel}_{\mathcal{B}_p(q)}$ where $\mathcal{B}_p(q)$ is the weighted Besov space. We also find the condition of measure ${\mu}$ such that ${\sup}_{a{\in}D}{\int}_D(k_a(z)(1-{\mid}a{\mid}^2)^{(p-a-1)})^{q/p}d{\mu}(z)$ < ${\infty}$.

  • The fundamental frequency (f0), representing an acoustic measure of vocal fold vibration, serves as an indicator of the speaker's emotional state and language-specific pattern in daily conversations. This study aimed to examine the f0 distribution in an English corpus of spontaneous speech, establishing normative data for American speakers. The corpus involved 40 participants engaging in free discussions on daily activities and personal viewpoints. Using Praat, f0 values were collected filtering outliers after removing nonspeech sounds and interviewer voices. Statistical analyses were performed with R. Results indicated a median f0 value of 145 Hz for all the speakers. The f0 values for all speakers exhibited a right-skewed, pointy distribution within a frequency range of 216 Hz from 75 Hz to 339 Hz. The female f0 range was wider than that of males, with a median of 113 Hz for males and 181 Hz for females. This spontaneous speech corpus provides valuable insights for linguists into f0 variation among individuals or groups in a language. Further research is encouraged to develop analytical and statistical measures for establishing reliable f0 standards for the general population.

  • Let B and S be the unit ball and the unit sphere in $\mathbb{C}^n$, respectively. Let ${\sigma}$ be the normalized Lebesgue measure on S. Define the Privalov spaces $N^P(B)\;(1\;<\;p\;<\;{\infty})$ by $$N^P(B)\;=\;\{\;f\;{\in}\;H(B) : \sup_{0 where H(B) is the space of all holomorphic functions in B. Let ${\varphi}$ be a holomorphic self-map of B. Let ${\mu}$ denote the pull-back measure ${\sigma}o({\varphi}^{\ast})^{-1}$. In this paper, we prove that the composition operator $C_{\varphi}$ is metrically bounded on $N^P$(B) if and only if ${\mu}(S(\zeta,\delta)){\le}C{\delta}^n$ for some constant C and $C_{\varphi}$ is metrically compact on $N^P(B)$ if and only if ${\mu}(S(\zeta,\delta))=o({\delta}^n)$ as ${\delta}\;{\downarrow}\;0$ uniformly in ${\zeta}\;\in\;S. Our results are an analogous results for Mac Cluer's Carleson-measure criterion for the boundedness or compactness of $C_{\varphi}$ on the Hardy spaces $H^P(B)$.

  • The purpose of this study were to measure brand personalities of deluxe hotels in Seoul, and to identify the difference of brand personality between local and international hotels. The questionnaires developed for this study were distributed to 460 employees in kitchen and F&B departments of 11 deluxe hotels in Seoul. A total of 398 questionnaires were used for anaylsis(86.5%) and the statistical analyses were completed using SPSS Win(12.0) for descriptive analysis, reliability analysis and t-test, and AMOS(5.0) for confirmatory factor analysis. The results of this study showed that deluxe hotels have brand personalities relatively strong at 'affection', 'sophistication', 'competence' dimensions, and there was a significant difference by hotel nationality. The brand personality scores of international brand hotels perceived by employees were high at the 'excitement'(p<0.001), 'sophistication'(p<0.001), and 'competence'(p<0.01) dimensions, whereas local hotels were considered more obedient(p<0.01). Overall, it could be a key factor for successful brand management that establish a distinctive brand personality, and a localized brand personality measure will lead to more desirable decision making.

  • Introduction: In this study, TLD 600 and TLD 700 pairs were used to measure the neutron dose of Elekta Precise medical linac. To this end, the optimum moderate thickness for the conversion of fast to thermal neutrons were evaluated. Materials and methods: 241Am-Be and 252Cf sources were simulated to calculate the optimum thicknesses of the moderator for the conversion of maximum fast neutrons (FN) into thermal neutrons (TN). Pair TLDs were used to measure F&TN doses for three different field sizes at four depths of the medical linac. Results: The maximum thickness of the moderator was optimized at 6 cm. The measurement results demonstrated that the TN dose increased with the expansion of field size and depth. The FN dose, which was converted TN, exhibits behaviors comparable to the TN due to its nature. Conclusion: This study presents the optimum thickness for the moderator to convert FN into TN and measure F&TN using TLDs.

  • We present a methodology that automatically selects indexing algorithms for each heading in Medical Subject Headings (MeSH), National Library of Medicine's vocabulary for indexing MEDLINE. While manually comparing indexing methods is manageable with a limited number of MeSH headings, a large number of them make automation of this selection desirable. Results show that this process can be automated, based on previously indexed MEDLINE citations. We find that AdaBoostM1 is better suited to index a group of MeSH hedings named Check Tags, and helps improve the micro F-measure from 0.5385 to 0.7157, and the macro F-measure from 0.4123 to 0.5387 (both p < 0.01).
