Purpose: Among many symptoms that the climacteric patients complain of, the major symptom is heat and cold sensation of body in various pattern. So, we are intended to study patterns of climacteric patients by using D.I.T.I. Methods: We studied 55 patients visiting OO Oriental Hospital from 1st January 2008 to 31th December 2008. The patients were distributed one of patterns by inspecting D.I.T.I. And we investigated the temperature of the region of body in 5 groups. Results: There are five groups in D.I.T.I. Those are heat sensation of face pattern, heat sensation of chest pattern, cold sensation of hand & foot pattern, heat sensation of hand pattern and cold sensation of lower abdomen pattern. 22 subjects are in heat sensation of face group. 12 subjects are in heat sensation of chest group. 12 subjects are in heat sensation of hand group. 6 subjects are in cold sensation of lower abdomen group. 3 subjects are in cold sensation of hand & foot group. Conclusion: 5 patterns of D.I.T.I is showed in climacteric patients. To help oriental medical diagnosis, further studies are needed.

Let D be an integral domain, P be a nonzero prime ideal of D, $\{P_{\alpha}{\mid}{\alpha}{\in}{\mathcal{A}}\}$ be a nonempty set of prime ideals of D, and $\{I_{\beta}{\mid}{\beta}{\in}{\mathcal{B}}\}$ be a nonempty family of ideals of D with ${\cap}_{{\beta}{\in}{\mathcal{B}}}I_{\beta}{\neq}(0)$. Consider the following conditions: (i) If $P{\subseteq}{\cup}_{{\alpha}{\in}{\mathcal{A}}}P_{\alpha}$, then $P=P_{\alpha}$ for some ${\alpha}{\in}{\mathcal{A}}$; (ii) If ${\cap}_{{\beta}{\in}{\mathcal{B}}}I_{\beta}{\subseteq}P$, then $I_{\beta}{\subseteq}P$ for some ${\beta}{\in}{\mathcal{B}}$. In this paper, we prove that D satisfies $(i){\Leftrightarrow}D$ is a generalized weakly factorial domain of ${\dim}(D)=1{\Rightarrow}D$ satisfies $(ii){\Leftrightarrow}D$ is a weakly Krull domain of dim(D) = 1. We also study the t-operation analogs of (i) and (ii).

This paper proves a new regularity criterion for solutions to the Cauchy problem of the 3D Boussinesq equations via one directional derivative of the horizontal component of the velocity field (i.e., (∂_iu₁; ∂_ju₂; 0) where i, j ∈ {1, 2, 3}) in the framework of the anisotropic Lebesgue spaces. More precisely, for 0 < T < ∞, if $$\large{\normalsize\displaystyle\smashmargin{2}{\int\nolimits_o}^T}({\HUGE\left\|{\small{\parallel}{\partial}_iu_1(t){\parallel}_{L^{\alpha}_{x_i}}}\right\|}{\small^{\gamma}_{L^{\beta}_{x_{\hat{i}}x_{\bar{i}}}}+}{\HUGE\left\|{\small{\parallel}{\partial}_iu_2(t){\parallel}_{L^{\alpha}_{x_j}}}\right\|}{\small^{\gamma}_{L^{\beta}_{x_{\hat{i}}x_{\bar{i}}}}})dt<{{\infty}},$$ where ${\frac{2}{{\gamma}}}+{\frac{1}{{\alpha}}}+{\frac{2}{{\beta}}}=m{\in}[1,{\frac{3}{2}})$ and ${\frac{3}{m}}{\leq}{\alpha}{\leq}{\beta}<{\frac{1}{m-1}}$, then the corresponding solution (u, θ) to the 3D Boussinesq equations is regular on [0, T]. Here, (i, ${\hat{i}}$, ${\tilde{i}}$) and (j, ${\hat{j}}$, ${\tilde{j}}$) belong to the permutation group on the set 𝕊₃ := {1, 2, 3}. This result reveals that the horizontal component of the velocity field plays a dominant role in regularity theory of the Boussinesq equations.

We consider a system of particles with locations { $X_{i}$ $^{n}$ (t):t$\geq$0,i＝1,…,n} in $R^{d}$ , time-varying weights { $A_{i}$ $^{n}$ (t) : t $\geq$0,i ＝ 1,…,n} and weighted empirical measure processes $V^{n}$ (t)＝1/n$\Sigma$$_{i=1}$$^{n}$ $A_{i}$ $^{n}$ (t)$\delta$ $X_{i}$ $^{n}$ (t), where $\delta$$_{x}$ is the Dirac measure. It is known that there exists the limit of { $V_{n}$ } in the week* topology on M( $R^{d}$ ) under suitable conditions. If { $X_{i}$ $^{n}$ , $A_{i}$ $^{n}$ , $V^{n}$ } satisfies some diffusion equations, applying Ito formula, we prove a central limit type theorem for the empirical process { $V^{n}$ }, i.e., we consider the convergence of the processes η$_{t}$ $^{n}$ ≡ n( $V^{n}$ -V). Besides, we study a characterization of its limit.t.

Objective : In the pain control, Bee Venom Acupuncture therapy is highly effective but cause allergic side-effects frequently. This study was performed to compare Bee Venom(BV) with BV Partner(BVP) in decreasing side-effects of BV. Methods : BV partner(BVP) which dilutes the Morus bombycis Koiduzumi Herbal Acupuncture was developed to decrease the side effects of the Bee Venom. We used D.I.T.I. to verify the effectiveness of BVP in decreasing side-effect of BV. We injected BV to Group I (n=18) at 4 points of body [Fengmen(風門 : B12), Feishu(肺兪 : B13), Fufen(附分 : B41), Pohu(魄戶 : B42)], and BVP to group II (N=18) at the same points. We observed the chages of temperature at beginning, 5 minutes, 1 hour, 1 day, 2days and 7days after injection. Results : The following results were obtained; 1. The difference of temperature had been continued until 2days in BV group, but 1day in BVP group. 2. The difference of temperature was significantly greater than time at 1hour in BV and at 5 minutes in BVP. 3. Other side-effects(the local pain, redness, angioedema and pruritus) were less appeared in BVP than BV group, too.

Fluorescence change of coumarin labeled phosphate binding protein (PBP-MDCC) was monitored to measure the amount of released inorganic phosphate ($P_{i}$) during nucleoside triphosphate (NTP) hydrolysis reaction. After purification of PBP-MDCC, fluorescence emission spectra showed that fluorescence responded linearly to $P_{i}$ up to about 0.7 molar ratio of $P_{i}$ to protein. The correlation of fluorescence signal and $P_{i}$ standard was measured to obtain [$P_{i}$] - fluorescence intensity standard curve on the stopped-flow instrument. When T7 bacteriophage helicase, double-stranded DNA unwinding enzyme using dTTP hydrolysis as an energy source, reacted with dTTP, the change of fluorescence was able to be converted to the amount of released $P_{i}$ by the $P_{i}$ standard curve. $P_{i}$ release results showed that single-stranded Ml3 DNA stimulated dTTP hydrolysis reaction several folds by T7 helicase. Instead of end point assay in NTP hydrolysis reaction, real time $P_{i}$-release assay by PBP-MDCC was proven to be very easy and convenient to measure released $P_{i}$.

In this paper, we consider anti-periodic solutions of the following BAM neural networks with multiple delays on time scales: $$\{{x^\Delta_i(t)=-a_i(t)e_i(x_i(t))+{\sum\limits^m_{j=1}}c_{ji}(t)f_j(y_j(t-{\tau}_{ji}))+I_i(t),\atop y^\Delta_j(t)=-b_j(t)h_j(y_j(t))+{\sum\limits^n_{i=1}}d_{ij}(t)g_i(x_i(t-{\delta}_{ij}))+J_j(t),}\$$ where i = 1, 2, ..., n,j = 1, 2, ..., m. Using some analysis skills and Lyapunov method, some sufficient conditions on the existence and exponential stability of the anti-periodic solution to the above system are established.

This study reports two cases of patients with cold hypersensitivity on hands and feet who were typed as the Soyangin. Although the two patients were experiencing the same symptom of cold hypersensitivity on hands and feet, we diagnosed one as a Soyangin Kyel-Hyung syndrome(結胸證) and the other as a Mang-eum syndrome(亡陰證). So we prescribed them Medications for Soyangin. And we used D.I.T.I.(Digital Infrared Thermal Imaging) to prove the improvement for cold hypersensitivity on hands and feet. The temperature change of D.I.T.I. after treatment showed that the main symptom After treatment, their symptoms were improved and the patients' D.I.T.I results also showed their improvement.

Cold hypersensitivity means a condition feeling cold at a temperature when one should not feel so. Cold hypersensitivity has been diagnosed based on the patient's subjective complaints. But these days, cold hypersensitivity can be diagnosed by the help of D.I.T.I.(Digital Infrared Thermal Imaging) This study is designed to verify the validity of diagnosis of cold hypersensitivity by D.I.T.I. Thermographic findings of 100 outpatients who visited the Kangnam Korean Hospital, KyungHee University, Seoul, Korea, from June 2000 to November 2000 were analyzed. The experimental group consisted of 50 patients who complained cold hypersensitivity, and for the control group, 50 patients who did not complain cold hypersensitivity. For the diagnosis of cold hypersensitivity of the hands, thermographic measurements were performed on two pairs of areas(palm-upper arm and back of hand-upper arm). And for that of the feet, other two pairs of areas(anterior thigh-top of the feet and posterior thigh-heel). When the criterion for thermal deviation between the palm and the upper arm was appointed as higher than $0.3^{\circ}C$, the sensitivity was 94.0% and the specificity, 90.0%. And when the criterion for that between the anterior thigh and the top of feet was appointed higher than $2.0^{\circ}C$, the sensitivity was 94.0% and the specificity, 76.0%. Through this study, the diagnostic standard for cold hypersensitivity of hands and feet could be presented.

Objective : The purpose of this study is to report the patient with peripheral neuropathy, who improved by Oriental medical treatment. Methods : The patient was managed by acupuncture, moxibustion, physical treatment and herbal medicine. We checked digital infrared thermographic imaging(D.I.T.I.), electromyography(E.M.G.), nerve conduction velocity(N.C.V.), deep tendon reflex(D.T.R.), sensory recover area and range of motion(R.O.M.) of knee & ankle. Results : After 6 week treatment, clinical sign(the movement and sense of leg) of improvement was appeared. Also E.M.G., N.C.V., D.T.R. and D.I.T.I. was recovered to nearly normal range. Conclusion : The results suggest that combination of acupunture, moxibustion and herbal medicine is good method for treatment of peripheral neuropathy. But further studies may be required to concretely prove the effectiveness of this methods for treating peripheral neuropathy.
