We construct bounded linear integral operators that giving solutions to the ${\bar{\partial}}$-equation in $L^p$-spaces and with compact supports on a q-convex intersection ($q{\geq}1$) with ${\mathcal{C}}^3$ boundary in $K{\ddot{a}}hler$ manifolds, and we apply it to obtain a Hartogs-like extension theorems for ${\bar{\partial}}$-closed forms for some bidegree.

In this paper, weighted Bloch spaces $\mathcal{B}_q$ are considered on the open unit ball in $\mathbb{C}^n$. In this paper, we will show that every Bloch function in $B_q$ induces a bounded linear functional on $L^1_a(\mathcal{B})$.

With the use of many rivers increased nearly to the capacity, the need for information concerning daily quantities of water and the total annual or seasonal runoff has became increased. A systematic record of the flow of a river is commonly made in terms of the mean daily discharge Since. a single observation of stage is converted into discharge by means of rating curve, it is essential that the stage discharge relations shall be accurately established. All rating curves have the looping effect due chiefly to channel storage and variation in surface slope. Loop rating curves are most characteristic on streams with somewhat flatter gradients and more constricted channels. The great majority of gauge readings are taken by unskilled observers once a day without any indication of whether the stage is rising or falling. Therefore, normal rating curves shall show one discharge for one gauge height, regardless of falling or rising stage. The above reasons call for the correction of the discharge measurements taken on either side of flood waves to the theoretical steady-state condition. The correction of the discharge measurement is to consider channel storage and variation in surface slope. (1) Channel storage As the surface elevation of a river rises, water is temporarily stored in the river channel. There fore, the actual discharge at the control section can be attained by substracting the rate of change of storage from the measured discharge. (2) Variation in surface slope From the Manning equation, the steady state discharge Q in a channel of given roughness and cross-section, is given as {{{{Q PROPTO SQRT { 1} }}}} When the slope is not equal, the actual discharge will be {{{{ { Q}_{r CDOT f } PROPTO SQRT { 1 +- TRIANGLE I} CDOT TRIANGLE I }}}} may be expressed in the form of {{{{ TRIANGLE I= { dh/dt} over {c } }}}} and the celerity is approximately equal to 1.3 times the mean watrr velocity. Therefore, The steady-state discharge can be estimated from the following equation. {{{{Q= { { Q}_{r CDOT f } } over { SQRT { (1 +- { A CDOT dh/dt} over {1.3 { Q}_{r CDOT f }I } )} } }}}} If a sufficient number of observations are available, an alternative procedure can be applied. A rating curve may be drawn as a median line through the uncorrected values. The values of {{{{ { 1} over {cI } }}}} can be yielded from the measured quantities of Qr$.$f and dh/dt by use of Eq. (7) and (8). From the 1/cI v. stage relationship, new vlues of 1/cI are obtained and inserted in Eq. (7) and (8) to yield the steady-state discharge Q. The new values of Q are then plotted against stage as the corrected steadystate curve.

The microwave dielectric properties and microstructure of the (1-x)$Mg_4Ta_2O_{9-x}TiO_2$(X=0, 0.3, 0.4) ceramic were, investigated. The specimens were prepared by the conventional mixed oxide method with sintering temperature of $1350^{\circ}C$∼$1425^{\circ}C$. According to the XRD patterns, the (1-x)$Mg_4Ta_2O_{9-x}TiO_2$(X=0, 0.3, 0.4) ceramics have the $Mg_4Ta_2O_{9}$ phase(hexagonal). The dielectric constant($\varepsilon$$_{\gamma}$) and density increased with sintering temperature and mole fraction of x. To improve the quality factor and the temperature coefficient of resonant frequency, TiO$_2$($\varepsilon_{r}$=100, $Q{\times}f_{r}$=40,000GHz, $\tau$$_{f}$=＋450 ppm/$^{\circ}C$) was added in $Mg_4Ta_2O_{9}$ ceramics. In the case of the $0.7Mg_4Ta_2O_{9}$-$0.3TiO_2$ and the $0.6Mg_4Ta_2O_{9}$-$0.4TiO_2$ceramics sintered at $1400^{\circ}C$ for 5hr., the microwave dielectric properties were $\varepsilon$$_{\gamma}$=11.72, $Q{\times}f_{r}$=126,419GHz, $\tau_{f}$=-31.82 ppm/$^{\circ}C$ and $\varepsilon_{r}$=12.19, $Q{\times}f_{r}$=109,411GHZ, $\tau$$_{f}$= -17.21 ppm/$^{\circ}C$, respectively.

Under the cancellation property and the Lipschitz condition on kernels, we prove that the Marcinkiewicz integrals defined on a homogeneous group H are bounded from $H^1$(H) to $L^1$(H), from $L_{c}$ $^{\infty}$(H) to BMO (H), and from $L^{p}$ (H) to $L^{p}$ (H) for 1 < p < $\infty$ assuming the $L^{q}$ -boundedness for some q > 1.for some q > 1.

The relationship between BAC(Blood Alcohol Concentrations) and BrACs(Breath Alcohol Concentrations) and also partition ratio of healthy Korean adult males (96 males) are researched in this paper and its dependency is described according to TBW (total body water), BMI (body mass index), BFM (body fat mass), and PBF (percentage of body fat). Among the above four variables, TBW affects significantly to the partition ratio compared to the other variables. The partition ratio of Korean healthy males showed 1,913 (95 % Confidence Interval (C.I.) from 1,889 to 1,937) for the whole time intervals. However, when Q was averaged after 60 minutes later, its values was 2,011 (95 % C.I. from 1,982 to 2,040). Bland-Altman plots showed the compatibility of measurement methods of multi-gas analyzer, and the biases according to the partition ratios (Q=2,100 and Q=1,913) gave -0.0052 % (95 % CI from -0.0059 to -0.0045%) and -0.0004 % (95 % CI from -0.0011 to +0.0003%), respectively.

In this paper we extend the two q-additions with powers in the umbrae, define a q-multinomial-coefficient, which implies a vector version of the q-binomial theorem, and an arbitrary complex power of a JHC power series is shown to be equivalent to a special case of the first q-Lauricella function. We then present several q-analogues of hypergeometric integral formulas from the two books by Exton and the paper by Choi and Rathie. We also find multiple q-analogues of hypergeometric integral formulas from the recent paper by Kim. Finally, we prove several multiple q-hypergeometric integral formulas emanating from a paper by Koschmieder, which are special cases of more general formulas by Exton.

단일상을 갖는 $Bi_2S_2CaCu_2O_{8+x}$ (2212)의 x-ray 분말 pattern을 a=5.408, c=30.83 $\AA$의 격자상수 및 역격자 벡터 $q^*=0.211b^*-c^*$을 갖는 pseudo tetragonal subcell을 이용하여 모두 index하였다. 임계온도 110K를 갖는 $Bi_2S_2CaCu_2O_{10+x}$ 상은 incommensurate supercell에 속하는 매우 많은 x-ray분말선들을 가지고 있다. Indixing guide로 전자회절사진(electron diffraction photographs)을 이용 x-ray분말 pattern에 대한 지수결정방법을 얻었다.$Bi_2S_2CaCu_2O_{10+x}$(2223)의 단위세표(unit cell)는 기하학적으로 격자상수 a=5.411, b=5.420, c=37.29(2) A을 갖는 orthorhombic subcell이다. Supercell반사 지수들은 subcell의 파 벡터 $\pm q^*=0.211b^*-0.78c^*$을 갖는 k,1지수로부터 영향을 받은 것이다. b 방향으로의 inconnensurate성분 $\delta$는 두 상에 대해 다 같으나, 2212에서 2223 상으로의 변환에 따라 c 방향으로의 초격자성분(superlattic component)은 connensurate($\varepsilon$=1)로부터 incommensurate($\varepsilon$=0.78)로 변한다.

1. Objectives and Methods The original insect of $Q\'{\i}C\'{a}o$ is described as the larvae of Holotrichia diomphalia Bates (Scarabaeidae) in oriental medicine literatures. Traditionally $Q\'{\i}C\'{a}o$ inhabit on rotting wood, compost, and organic debris of soil or thatched roofs. They have the very important distinguishing mark that wriggle along on their back through rotting wood, compost etc. and they never do inflict the living crops. but, Holotrichia diomphalia Bates as the $Q\'{\i}C\'{a}o$ is not right because of many questions, such as Holotrichia are the harmful insects eat into farm products, and those don't match well with korean farmers' moods if their cultivated lands are turned over for collecting $Q\'{\i}C\'{a}o$ larvae, and especially they don't go on using their back. 2. Results and Conclusions Accordingly, in the conclusion of this subject it is reported that the original insect of $Q\'{\i}C\'{a}o$ is the larvae of Korean Cetoniidae(Coleoptera; Scarabaeoidea) insects including Genus Protaetia Burmeister(Protaetia orientalis submarmorea Burmeister, P.brevitarsis seulensis Kolbe, etc.) and the larvae of Korean Cetoniinae insects. Also, those were the original larvae of $Q\'{\i}C\'{a}o$ that were applied to not only 'DongEuiBoGam' but also 'Dongyi Suse Bowon prescriptions'. Those feed on rotting wood, compost, and organic debris of soil or thatched roofs.
