This study begins at Korean learning skill improvement and ends in 'how does the motivated learns achieve their goals by solving problems'. Strategy means the general plans for how to solve the problems. Strategic knowledge that is needed in the process of problems solving means the knowledge for learners to plan and manage the problem. Strategy is a kind of knowledge over each process, so it's a guidance that have learners choose the proper informations and functions, and decide when and how learners apply them. Strategy is the method that learners choose the sub-goals to achieve the final solution and it's important with respect to becoming an actual help to find the solution. Strategies that have been developed so far come from learning one. So we need to utilize Korean language strategy in teaching and learning. In this study, I research in the change of Korean educational view, conceptional matter for function and strategy, Korean language using strategy and procedure. Knowledge, strategy, automation, a role of higher rank perception for using strategy, the kinds of strategy in Korean language teaching and learning and the applied procedure in class. In conclusion, the teachers need the proper strategies for the students to solve the problem and achieve the goals and we need to develop the strategies constantly and achieve the goals. And we need to develop the strategies to use them so much.

On the purpose of epidemiological survey relate to food poisoning, a total of 114 samples of different salads collected from fast food Restaurants in Gyeonggi-do were for the presence of pathogenic microorganisms. Microbial assessment of salads revealed that TPC(l.1×10~8.4×10^5 CFU/g) and coliforms(O~5.4×10₄ CFU/g) exceeded the standards by Solberg et al.(TPC:10^5 CFU/g, coliforms:10² CFU/g).<br/> Two pathogenic bacteria were isolated from salad samples, and identified by biochemical methods, including API identification systems.<br/> Isolates from PALCAM agar and MYP agar media were in 98.6, 99.8% agreements with Listeria monocytogenes, Bacillus cereus at the species level, respectively. All 7 strains of Bacillus cereus isolates produced enterotoxin as revealed with CRET-RPLA,

This study was performed to survey distribution of microorganisms and food-borne pathogenic bacterium in order to estimate microbiological safety in seonsik and saengsik. Total aerobic bacteria was detected over 10^5 CFU/g in raw materials(4.3%) and products(35.7%) of saengsik. Coliforms were detected over 10² CFU/g in seonsik products(27.3%) and in raw materials(4.3%) and products(35.7%) of saengsik. Cl. perfringens was detected in saengsik products(4.8%). B. cereus was detected in raw materials(12.5%) and products(18.2%) of seonsik and raw materials(13.0%) and products(23.8%) of saengsik. Concentration and detection rate of microorganisms in products were higher than raw materials.<br/> These results show some food hygiene problems but do not cause food poisoning because concentration of Clostridium perfringens and B. cereus were lower than 10^5 CFU/g.

This study was carried out to investigate the presence of L. pneumophila in indoor air and water collected from 692 air conditioning cooling towers at different public facilities. For these 4 years (2001~2004) of investigation, water samples were collected in high air conditioner operating month (from July to September) at department stores, hotels, offices, hospitals, discount stores, and public agencies. It was found that L. pneumophila was present in water samples from 47 air conditioning cooling towers. The detection rate of L. pneumophila was 7.6% in 2001, 10.7% in 2002, and 9.5% in 2003, respectively. When we compared the 4 air conditioner operating months, the highest rate of L. pneumophila detection was obtained in the water samples of July. The detection rate of L. pneumophila differed among different facilities. The highest detection rate of 17.9% was found in samples from department stores. L. pneumophila was detected similarly in water samples from hospitals (8.3%) and offices (8.2%). pH, temperature, and turbidity in the 47 L. pneumophila positive water samples ranged from pH 7 to 9, from 25℃ to 38℃, and from 1.0 to 3.5, respectively.
