Interoperability is the key issue in NCW. However, old-fashioned weapon systems have low level interoperability. The representative example is BTCS. Therefore, we apply KVMF R1 to BTCS in order to improve interoperability and testify the effectiveness of how to apply without any changes in existing software. In this paper, we have proposed a message and software architecture design method for applying KVMF to developed weapon system. Finally, it is confirmed that the proposed method is superior to apply KVMF to existing weapon system in a point of verifying how to highly efficiently apply KVMF on existing weapon system.

The purpose of this research is to develop a service R&D concept definition and finding service R&D demand in Korea. It is necessary to develop an effective service R&D model to improve the competitiveness of the service industry. A survey model for finding service R&D demands has been developed through extensive discussions with experts. A demand survey for 91 experts in service industry and academia has been conducted to find relative weights of each service R&D category. Several other aspects on service R&D has beed investigated to analyze the relative importance of service R&D subjects. And a benchmarking on previous service R&D research investment has been performed. Past and present service R&D topics are compared as a whole and by each individual domain. A service R&D framework and important funding areas has been suggested. The results of this research can be used for research fund allocation decisions for strengthening service industry competitiveness.

This paper investigates the performance of technology innovation activities performed by firms in 16 major regions in Korea using 2002-2010 survey data by STEPI. The theoretical and empirical analysis is carried out via the 2 models which are the simple R&D - total revenue model and Cobb-Douglas model based on the simple model adding labor variable. The main results shows that for simple model, the R&D elasticity for total revenue is 0.42 for all areas and Ul-San shows the highest elasticity level, 0.66 and Bu-San the lowest level, 0.2. In case of Cobb Douglas model the R&D elasticities are not statistically significant for many regions. To overcome the low statistical significance, we grouped the 15 regions for 3 wider regions using ANOVA based on the R&D intensity for the homogeneity of R&D activities. By grouping, each region has more observations to analyze and the results from the empirical analysis shows higher statistical significance level and data explanation capability. In this case, Group 3 which shows larger firm size and slightly higher export share shows the highest level of R&D elasticity, 0.088 and Group 1 which has the smallest firm size and the lowest revenue growth rate shows the lowest level, 0.31. For the labor elasticity, Group 1 shows the higest level, 1.16 and Group2 the lowest level, 1.096. These results show that the regions which have many middle and small firms reveal low R&D-revenue elasticity and high labor-revenue elasticity.

Purpose: This study evaluated gender differences and extents of accumulation on chronic dose of CJ-1l555 using rats. Method: 0, 10, 50 and 200 mg/kg/day of CJ-11555 (0.5% CMC) were orally administered to rats for 28 days and observed toxicokinetic parameters. Plasma concentrations were analyzed by LC-MS/MS Result: Exposure to CJ-11555 increased with the increase in dose level for both sexes. Mean concentrations at 10 and 50 mg/kg/day were generally similar an Days 1 and 28, but were generally highter on Day 28 than on Day 1 at 200 mg/kg/day. (omitted)

A 14.1" XGA (1024${\times}$768) LCD panel with Integrated Black Data Insertion (IBDI) has been world first developed successfully based on the integrated amorphous Silicon TFT gate driver which we previously introduced. The notable features compared with the conventional integrated a-Si TFT gate driver circuit are that the circuit consists of Dual buffer, Carry buffer structure, and Q-node cross charging for stable signal scanning characteristic and prevention of coupling between signal lines.

Let (R,m) be a commutative Noetherian local ring. In this paper we show that a finitely generated R-module M of dimension d is Cohen-Macaulay if and only if there exists a proper ideal I of R such that depth($M/I^nM$) = d for $n{\gg}0$. Also we show that, if dim(R) = d and $I_1{\subset}\;{\cdots}\;{\subset}I_n$ is a chain of ideals of R such that $R/I_k$ is maximal Cohen-Macaulay for all k, then $n{\leq}{\ell}_R(R/(a_1,{\ldots},a_d)R)$ for every system of parameters $a1,{\ldots},a_d$ of R. Also, in the case where dim(R) = 2, we prove that the ideal transform $D_m(R/p)$ is minimax balanced big Cohen-Macaulay, for every $p{\in}Assh_R$(R), and we give some equivalent conditions for this ideal transform being maximal Cohen-Macaulay.

The detailed $^1$H and $^{13}$ C NMR assignments of a novel sucrose isovaleryl ester isolated from the seed of Euphorbia Lathyris L., were achieved by one-and two-dimensional techniques. The new sucrose ester was characterized as an $\alpha$-D-glucopyranoside, 3,4,6-tris-O-(3-methyl-1-oxobutyl)-$\beta$-D-fructofuranosyl, 2,6-bis(3-methylbutanoate); sucrose 4,7,8,11,12-pentaisovalerate by MS and NMR experiments.

Caffeine is widely used in cosmetics and hair care products. Although its efficacy in stimulating hair growth has been confirmed in recent studies, its mechanism of action remains unelucidated. The present study aimed to determine the effects of caffeine on hair growth, with a focus on intracellular hair follicle activity. Experiments included in vitro and ex vivo tests, and a clinical study. Caffeine enhanced the cellular activity and potassium channel opening. It also promoted human hair follicle elongation. Immunohistochemical staining showed that the Ki-67 signal was significantly higher in cells treated with caffeine. These efficacies of caffeine were comprehensively demonstrated in clinical results, wherein caffeine-containing shampoo improved hair density after 24 weeks of testing. Collectively, the results of this study demonstrated that caffeine promoted hair growth and inhibited the progression of hair loss by enhancing intracellular activity of hair follicles.
