Objectives : This research was performed to investigate the effect of acupuncture using invasive low level laser therapy (LLLT) at Yolgyol (LU7) + Yogu (LR5) on weight gain, food intake, food efficiency, lipid metabolism, atherogenic index, HTR (HDL-cholesterol to total cholesterol ratio) and morphological change of hepatic tissue in hyperlipdemia rats. Methods : Experimental groups were divided into high fat diet group (Control group), high fat diet and acupuncture therapy group at LU7 + LR5 (AT group), high fat diet and acupuncture group using 10 mW LLLT at LU7 +LR5 (LA10 group), high fat diet and acupuncture group using 20 mW LLLT at LU7+LR5(LA20 group), high fat diet and acupuncture group using 60 mW LLLT at LU7 + LR5 (LA60 group), once per 3 days during 9 weeks. Results : Body weight was decreased significantly in AT and LA20 groups compared with Control group. Food intake was increased significantly in LA60 group compared with Control group. Food efficiency was decreased significantly in LA10, LA20 and LA60 groups compared with control group. In the lipid metabolism, total cholesterol was decreased significantly in AT, LA10, LA20 and LA60 groups, triglyceride was decreased significantly in LA10, LA20 and LA60 groups, TG/HDL-cholesterol ratio was decreased significantly in LA 60 group compared with control group. In the morphological change, hepatic tissue were not showed balloning degeneration and irregular arrangement of hepatic cell in LA10 and LA20 groups with control group. Conclusions : Acupuncture using LLLT at LU7+LR5 can manage hyperlipemia by controlling body weight, food intake, food efficiency ratio and lipid metabolism.

This paper introduces new ordering algorithms using the graph of data structure and forward/backward substitution of LU decomposition using recursive function. The performance of the algorithm is compared with Tinney's algorithm using 14 bus systems. Test results show that the new fill-in element of Jacobian matrix using the proposed ordering algorithm is same as that of Tinner scheme 3 and the forward/backward substitution can reduce the computation time

The new ion exchange resin was synthesized from chloromethylated styrene-1,4-divinylbenzene(DVB) with 1-aza-15-crown-5 macrocyclic ligand by substitution reaction. The effect of pH, time, dielectric constant of solvent and cross-linked of the matrix on the adsorption for $UO_2^{2+}$, $Ca^{2}$ and $Lu^{3+}$ was investigated. The metal ion was not adsorbed on the resins below pH 3 but above pH 4 fast adsorption behavior was showed. The optimum equilibrium time for adsorption of metallic ions was two hours. The adsorption selectivity determined in ethanol matrix was in increasing order $UO_2^{2+}>Ca^{2}>Lu^{3+}$. The adsorption power was in the order of 1%, 2%, 10% and 20% -crosslinked resin, but adsorption properties of resins decreased in proportion to the order of dielectric constant of solvents used. In addition, these metal ions could be separated in the column packed with 1% crosslinked resin by pH2.5 $HNO_3$ as an eluent.

Bombesin receptors are overexpressed in many kinds of human tumors. In particular, the gastrin releasing peptide receptor (GRPR) which is also called bombesin receptor subtype 2, has been identified in prostate cancer. In the present study, we developed a bombesin antagonist-based $^{177}Lu$-labeled peptide, $^{177}Lu$-DOTA-$Ala(SO_3H)$-Aminooctanoyl-Gln-Trp-Ala-Val-N methyl Gly-His-Statine-Leu-$NH_2$ (DOTA-sBBNA). DOTA-sBBNA was prepared using a solid phase synthesis method. It was labeled with $^{177}Lu$ by a high radiolabeling yield (>98%), and its Log P value was -2.05. The radiolabeled peptide was highly stable in serum incubation at $37^{\circ}C$ for 48 hr. A competitive displacement of $^{125}I-[Tyr^4]$-Bombesin on the PC-3 human prostate carcinoma cells revealed that the $IC_{50}$ value of the peptide was 6.76 nM indicating a highly nanomolar binding affinity for GRPR. These results suggest that $^{177}Lu$-DOTA-sBBNA can be a potential candidate for targeting prostate cancer, and further studies to evaluate its biological characteristics are needed.

A study has been made for the investigation of the robustness and convergence of various implicit operators of the LU-SGS scheme using linear stability analysis. It is shown that the behavior of the implicit operator is not determined by its own characteristics, but is determined relatively depending on the dissipative property of the explicit operator. It is also shown that, as the dissipation level of the implicit operator increases, the robustness of the scheme increases, but the convergence rate can be deteriorated due to the excessive dissipation. The numerical results demonstrate that the dissipation level of the impliict operator needs to be higher than that of the explicit operator for computing stiff problems.

Nutrient balance is important to develop environmentally friendly agriculture. Phosphorus surplus in nutrient balance was more serious than that of nitrogen. Nitrogen and phosphorus exceeded twice the requirement at 30 cities/counties and 32 among 165, respectively. Given livestock waste and optimal nutrient balance, the proper number of animal feeding was 1.68LU/ha. Considering livestock waste only, the optimal number of livestock feeding was 3,918,000LU (heads) and, including fertilizer that would be 2,288,000LU. It is recommended to introduce the regional control system to regulate nutrient input and output, and the trading system of livestock feeding rights to control that.

This study was performed to investigate the serum creative kinase(CK) activity and CK isoenzyme in Jindo dog. Serum CK activity and CK-isoenzyme were analyzed in 53 Jindo dogs of both sexes. The mean value and normal range of serum CK activity were 24.1 lu/$\ell$ and 7-91 lu/$\ell$, respectively, in 29 female dogs, 24.8 lu/$\ell$ and 8-89 lu/$\ell$ in 24 male dogs. The CK activity of the Puppy showed a tendency to be higher than that of the adult. There was no significance between Puppy and adult. Three isoenzymes (CK-MM, CK- BB, and CK-MB) were recognized in serum. The mean percentages of female and male were as follows: 48.31fp and 48.1% for CK-MM, 35.49) and 33.61fp for CK-BB, and 8.2% and 10.1% for CK-MB in the puppy and 46.21% and 46.1 % for CK-MM, 36.3% and 37.6% for CK-BB and 10.5% and 9.5% for CK-MB in the adult.

In this report, cerium doped lutetium aluminate ($Lu_3Al_5O_{12}$:Ce) phosphor has been synthesized by the solid state method under reduction atmosphere with mixture gas. The prepared phosphor shows a main luminescent peak at 555nm. Consequently, this phosphor is possible to be applicable to white LED lamp by InGaN chips.

Single crystalline, $LuFe_2O_4$, was grown by the floating zone method. The crystal structure was a two-dimensional layered-type rhombohedral($R\={3}mh$) structure, with an $a_0=3.440(2)\;{\AA}\;and\;a\;c_0=25.263(2)\;{\AA}$. The magnetic $N\'{e}el$ temperature($T_N$) was determined to be 250 K. The $M\"{o}ssbauer$ spectrum at 12 K was fitted with four sextet sets which was resulted from the crystal structure. The spectrm at room temperature consisted of three singlets and a doublet with the electric quadrupole splitting. The isomer shift($\delta$) value of the singlet was $0.20{\pm}0.01mm/s$ relative to the Fe metal indicating the $Fe^{3+}$ valence state, and the value of the doublet was $0.70{\pm}0.01mm/s$ indicating $Fe^{2+}$. The $M\"{o}ssbauer$ absorption area ratio between $Fe^{3+}$ and $Fe^{2+}$ at room temperature was 1:1. The doublet phase of spectra gradually disappears by up to 360 K. At 360 K, the spectrum shows the singlet phase. We suggested that the spontaneous polarization effect of $LuFe_2O_4$ was caused by the change of iron behavior.
