A $CH_3Cl$ extract from the flower of Lonicera japonica (Lauraceae) significantly protected primary cultures of rat cortical cells injured by the excitotoxic amino acid, L-glutamate. Loganin (1), secoxyloganin (2), caffeic acid (3) rutin (4), hyperoside (5), quercetin-3-O-glucoside (6), lonicerin (7), kaempferol-3-O-rutinoside (8), luteolin-7-O-b-D-glucopyranoside (9), quercetin (10) and luteolin (11) were isolated by bioactivity-guided fractionation from the $CH_3Cl$ fraction and further separated using chromatographic techniques. Caffeic acid, lonicerin, kaempferol-3-O-rutinoside, quercetin and luteolin had significant neuroprotective activities against glutamate-induced neurotoxicity in primary cultures of rat cortical cells at concentrations ranging from $0.1{\mu}M$ to $10.0\;{\mu}M$.

The green-emitting CeMgAl11O19:Tb (CMAT) phosphor has been prepared at 1200 °C by the simple solid-state reaction using AlF3 as a self-flux. This preparation temperature is much lower than those (1500-1700 °C) for conventional solid-state reaction and spray pyrolysis method. In particular, the complete process to produce high-quality phosphor particles was carried out through the single-step heat treatment of the mixture of corresponding oxide-type metal sources. An addition of AlF3 as a self-flux significantly decreased the crystallization temperature of CMAT with plate-like shape. The particle morphology could be controlled from plate-like to spherical by using H3BO3 as an additional flux. Thus, an optimal morphology and luminescence characteristics of CMAT were achieved when both AlF3 and H3BO3 fluxes were simultaneously used. Compared with conventional solid-state process, which is accompanied by the calcination step(s), and other alternative liquid solution techniques such as sol-gel method and spray pyrolysis, no use of active precursors and liquid media that are harmful to the environment is a distinctive advantage for the industrial purpose.

The purpose of this study is to analyze the success factors of the Sam Bo Hwa Seong Co., Ltd. this research is case study. In order to accomplish the objective, 1 had personal interview with the present Kim and reviewed business policy and company regulation. The main success factors of the Sam Bo Hwa Seong corporation are as following: first, a large experience of the top management, second, the artisan spirit and a mission sense of the CEO, third, a strong thrust of the present Kim, fourth, the partnership between labor and management, fifth, an exhaustive credit and a perfect quality control, sixth, research and development investment for the technical improvement. The result of this research will be a useful information to the management in small-medium firms and to the reserve management who wants establishment of the corporation.

It was first time that low frequency R.F. derived plasma enhanced MOCVD with frimethylborate precursor was used to fabricate a new ternary compound $BO_{x}$ $N_{y}$ . The formation of BON molecule was resulted from nitrogen nitrifying B-O, and forming the angular molecule structure proved by XPS and FT-IR results. The relationship between hardness and film thickness was studied. An thickness-independent hardness was fond about 10 GPa. The empirical calculation of band-gap and UV test result showed that our deposited $BO_{x}$ $N_{y}$ thin film was semiconductor material with 3.4eV of wide band gap. The electrical conductivity, $4.8$\times$10^{-2}$ /($\Omega$.cm)$^{-1}$ also confirmed that $BO_{x}$ $N_{y}$ has a semiconductor property. The roughness detected from the as-grown films showed that there was no serious bombarding effect due to anion in the plasma occurring in the RF frequency derived plasma.

To determine availability as a feed source of deer of by-products that produced at reforestation areas and comprised shrubs and wild grasses, mixed forest by-product silage(FBS), arrowroot silage(ARS), bristletooth oak tree silage(BOS), white oak tree silage(WOS) were prepared to compare dry matter intake, digestibility and nitrogen balance in digestion balance trials with spotted deer. Dry matter intake was highest in WOS and lowest in ARS but there was no significant difference(P＞0.05). Digestible dry matter intake was higher in FBS and ARS that had higher dry matter digestibility than in WOS and BOS that had lower dry matter digestibility(P＞0.05). Dry matter digestibility was highest fur ARS and lowest for BOS(P＜0.05). Digestibility of crude protein was similar to that of dry matter. That of crude fiber was higher for FBS and ARS than for BOS and WOS(P＞0.05). Daily gain of body weight was slightly greater for WOS than fer other treatments(P＞0.05). Nitrogen intake was highest for ARS and lowest for BOS(P＜0.05), and fecal nitrogen was opposite to nitrogen intake(P＜0.05). Nitrogen excretion with urine was highest for ARS that had higher nitrogen intake and lowest for BOS and there was a significant difference(P＜0.05). Retained nitrogen was highest for FBS and lowest for. BOS (P＞0.05). Although there was no significant difference(P＞0.05): the ration of nitrogen intake to retained nitrogen was highest in FBS for 43.9% and lowest in BOS for 24.7%. Consequently because by-products that produced at reforestation areas had high intake and internal availability, it was evaluated to valuable feed source for deer.
