모바일 소프트웨어의 생산성을 높이고 신뢰성 있는 소프트웨어를 개발하기 위한 모바일 소프트웨어 테스트의 중요성이 부각되고 있다. 모바일 소프트웨어의 테스팅 기술이 효율적으로 적용되기 위해서는 모바일 플랫폼 기반의 테스트를 자동화 할 수 있는 기술이 필요하다. 즉, 모바일 플랫폼에서 제공하는API를 테스트 하기 위한 테스트케이스를 생성할 수 있는 기법이 필요하다. 테스트케이스를 생성하게 되면 소프트웨어의 생산성과 신뢰성을 향상 시킬 수 있을 뿐만 아니라, 테스트 기간 및 비용을 줄일 수 있다는 이점이 있다. 본 논문에서는 기존의 테스트 자동화에 관련된 연구와 테스트 자동화 도구에 대한 연구를 통해 테스트케이스 생성 범위를 설정하고, J2ME 플랫폼에 사용될 수 있는 테스트케이스 생성 기법인 키워드 방식 기법(Keyword Driven Method)을 제시하였으며, 제안한 생성 기법을 적용하여 J2ME 플랫폼 기반의 테스트에 활용 가능한 테스트케이스 생성 기법이 되도록 하였다.

The aim of the current study was to evaluate the transport system in EMT-6 cell for the uptake of the methylmercury(MeHg). Several inhibitors ere used to test used to test which potential transport system might be involoved in MeHg uptake. Probenecid was used to test the organic transport system, valinomycin for testing the effect of the membrane potential, cytochalasin B for testing the facilitated diffusive D-glucose transport system and colchicine for testing the microtubule system. Ouabain for evaluating active transport system, 4',4-diisothiocyano-2',2-stilbenedisulfonic acid(DIDS) the Cl- ion transport system and verapamil for the $Ca^{2+}$ transprot system. Significantly, MeHg decreased the synthesis of nitric oxcide(NO) and intracellular ATP in ENT-6 cells. In the condition of ouabain containing with MeHg decreased the production of NO and intracelluar ATP. In the treatment of inhibitors, ouabain showed protective effect against cytotoxicity of MeHg but ather inhibitors not showed protective effects. The protective effects of ouabain against the cytotoxicity of MeHg deoended on the concentration of added ouabain to the culture medium for MET-6 cells. These result showed that the uptake of MeHg might be involved in the active transport system. Active transports system seems to share similarities with the transport systems for the uptake of MeHg when using MeHg and MeHg-glutathione complex.x.

Sero-epidemiological study was carried out to observe the prevalence of brucellosis in 500 slaughtered as well as in 500 healthy animals in Peshawar district of N.W.F.P. All serum samples were subjected to four serological tests i.e. Standard Plate Test (SPT), Standard Tube Test (STT), Rivanol Test (RV) and 2, Mercapto-Ethanol Test (2, ME). The incidence of disease in 500 healthy animals tested by standard plate test, standard tube test, rivanol test and 2, Mercapto-ethanol test, was 2.8%, 1.8%, 1.6% and 1.2% respectively. While the incidence of brucellosis in 500 slaughter animals from Peshawar abattoir was 3.0%, 2.2%, 2.00% and 1.2% by standard plate test, standard tube test, rivanol test and 2, Mercapto-ethanol test The disease prevalence was higher in slaughtered animals as compared to healthy animals. The disease was more common in goats than sheep, also more prevalence in aged female than younger stocks. The efficacy of SPT was found more effective as compared to STT, RV, and 2, ME tests both in slaughtered as well as apparently healthy animals at Peshawar district. Standard Plate test detected 2.9%, Standard Tube test 2.0%, Rivanol test 1.8% and 2, Mercapto-ethanol test detected 1.2% positive cases in slaughtered as well as in healthy animals. So the Standard Plate Test was found to be more reliable, sensitive, and easy to performed.

Against the mutagen MNNG and NOPD with SOS chromotest, the antigenotoxic activity of MeOH-soluble extract was much more effective than that of the water-soluble one. When the extract was added to the certain concentration, the antigenotoxic acivity was enhanced. Against the mutagen NOPD with Ames test, the antimutagenic activity of MeOH-soluble extract was better than that of the water-soluble one. The 60.4% of the inhibition ratio for the revertant colony-forming unit was shown at 5 mg of MeOH-soluble extract per plate. Antimutagenecity test with SOS chromotest and Ames test were performed using water-soluble and MeOH-soluble extracts from of Gleditsia sinensis. The antioxidant activity of MeOH-soluble extract with the NBT method was higher than that of the water-soluble one.

Objective: An experiment was conducted to determine digestible energy (DE) and metabolizable energy (ME) of different byproduct feed ingredients fed to growing pigs, and to generate prediction equations for the DE and ME in feed ingredients. Methods: Twelve barrows with an initial mean body weight of 31.8 kg were individually housed in metabolism crates that were equipped with a feeder and a nipple drinker. A $12{\times}10$ incomplete Latin square design was employed with 12 dietary treatments, 10 periods, and 12 animals. A basal diet was prepared to mainly contain the corn and soybean meal (SBM). Eleven additional diets were formulated to contain 30% of each test ingredient. All diets contained the same proportion of corn:SBM ratio at 4.14:1. The difference procedure was used to calculate the DE and ME in experimental ingredients. The in vitro dry matter disappearance for each test ingredient was determined. Results: The DE and ME values in the SBM sources were greater (p<0.05) than those in other ingredients except high-protein distillers dried grains. However, DE and ME values in tapioca distillers dried grains (TDDG) were the lowest (p<0.05). The most suitable regression equations for the DE and ME concentrations (kcal/kg on the dry matter [DM] basis) in the test ingredients were: $DE=5,528-(156{\times}ash)-(32.4{\times}neutral\;detergent\;fiber\;[NDF])$ with root mean square error = 232, $R^2=0.958$, and p<0.001; $ME=5,243-(153 ash)-(30.7{\times}NDF)$ with root mean square error = 277, $R^2=0.936$, and p<0.001. All independent variables are in % on the DM basis. Conclusion: The energy concentrations were greater in the SBM sources and were the least in the TDDG. The ash and NDF concentrations can be used to estimate the energy concentrations in the byproducts from oil-extraction and distillation processes.

The antimutagenic activity of polysaccharides extracted from soybeans fermented with Agrocybe cylindracea (AC) or Phellinus igniarius (PI) against 2-amino-3,8-dimethylimidaxo[4,5-f]quinoxaline (MeIQx) was examined using a Salmonella/Ames test and host-mediated assay in mice. The polysaccharides from the soybeans fermented with A. Cylindracea and P. igniarius inhibited the mutagenic acitivity of the cooked food mutagen, MeIQx, by 31.2% and 35.3%, respectively. The polysaccharides also inhibited MeIQx genotoxicity in a dose-dependent manner in micel. These results suggest that the polysaccharides from soybeans fermented with A. cylindracea or P. igniarius exhibit antimutagenic properties against MeIQx in vitro and in vivo.

The RF system for PEFP 20MeV proton linear accelerator is described. The RF system for 3MeV RFQ was already installed and operated to drive the RFQ. The klystron was tested up to 600kW itself and operated up to 350kW routinely. The HPRF dummy load was stabilized with the change of the coolant. Preparation of 20MeV DTL HPRF test has been completed. LCP and PLC system for klystron power supply was already prepared. Voltage fluctuation was measured during klystron test. Voltage control feedback loop seems to be re-adjusted.
