  • The purpose of this study was to look into trends in research concerned with children's counting in Korea. A total of 59 studies on counting including journal articles, master's & doctoral theses were analyzed in terms of the period of time, content, and research methods. The results showed that 1) ${\frac{1}{3}}$ of the total studies on counting were published in 2001~2005, 2) the most frequent content was the developmental trend of young children's counting ability and then the relation between counting ability and various mathematical competence, 3) most of the studies targeted normal early childhood children from 3~5 years old and used the quantitative method. These results showed that the domestic research on counting have limits in the research topics, subjects, and methodology. The researcher presents three suggestions for further research. Frist, topics that are not enough revealed in the previous studies, for examples, counting backwards, counting by collections such as tens, fives, twos, and counting errors in young children need to be further studied. Second, counting behavior and ability of young children under 3 years olds need to be investigated. Third, there is a need to increase the studies using qualitative methods.

  • This study was carried out to investigate the effects of washing time and the addition of sodium chloride(2%) on the quality characteristics of surimi made with chicken breast. The control(C) prepared from Alaska pollack was washed 2 times without sodium chloride. For the test treatments, ground chicken breast was washed 2 times only(T1), washed 2 times followed by the addition of sodium chloride(T2), washed 3 times(T3), washed 4 times with added sodium chloride(T4), washed 6 times(T5), and washed 6 times with added sodium chloride(T6) to produce chicken breast surimi. The $L^*,\;a^*$, W, shear force, and juiciness values were significantly higher, but the hardness, cohesiveness, gumminess, chewiness, aroma, flavor, and overall acceptability of Tl were significantly lower than those of the control(p<0.05). The $L^*$ value decreased as the washing time increased, and the $a^*$ and W values were significantly higher, however the hardness, breaking force, gel strength, shear force, and overall sensory scores of the samples washed 2 times were lower than those washed 4 and 6 times (p<0.05). The $L^*,\;b^*$, and shear force values were significantly lower but the $a^*$, W, hardness, cohesiveness, gumminess, chewiness, folding test results and overall sensory scores were significantly higher due to the addition of sodium chloride (p<0.05). The correlation coefficients(r>0.6) for the overall sensory scores and other items were positive for the folding test, cohesiveness, gumminess, chewiness, and flavor, but negative for shear force(p<0.05). Overall, T4 had the highest qualities and economic value among all treatments.

  • The effects of steeping and washing were investigated in the physicochemical properties of acorn flour. The contents of crude protein, ash and total phenol of acm flour were gradually decreased with the steeping days and washing times. However, the contents of crude fat and dietary fiber were little different. The more steeping days and/or washing times became large, the more the color of acorn flour became light. Swelling power was enhanced by increasing of steeping days and washing times but solubility was some decreased Water binding capacity was decreased and intrinsic viscosity was increased with the increased steeping days and washing times. Washing times were more influential than steeping days to those changes.

  • This study investigated tree vigor of damaged forest by Thecodiplosis japonensis Uchida et Inouye. In damaged forest by pine gall midge, the investigation result of damaged rate section (severe, moderate, light) indicated that severe stand showed higher value of electric resistance ($k{\Omega}$) than that of light stand, the investigation result of tree density section(crowed, middle, little) indicated that crowed stand showed higher value of electric resistance than that of little stand (the value of electric resistance at which low reading show high vigor tree and high reading low vigor tree). The crown width and DBH (diameter of breast height) of external factors showed lower value of electric resistance than that of small size. The results of comparative between Crown area and value of electric resistance in each stand were $13.4m^2$ in severe stand, $10.9m^2$ in moderate stand and $7.9m^2$ in light stand. Therefore, the tree which have big crown showed low value of electric resistance (below $15k{\Omega}$)that has high possible of survial.

  • The objectives of this study were to evaluate the effects of some seed pretreatments on seed germination, emergence, growth and yield of Bupleurum falcatum L. Seed treatments included stratification in open-field during winter, washing with running water, low temperature storage, soaking into $H_2SO_4$ solution, and scarification. Germination increased 15% by stratification and 9% by washing treatment compared to non-treatment, control. It was suggested that washing treatment leached inhibiting substance, while stratification treatment leached inhibiting substance and promoted growth of immatured embryo. In the field mulched with rice straw, stratification and washing treatments were effective to shorten days to emergence by 31 and 21 days and to increase emergence rate by 7 and 5 %, respectively, compared with control. By these two treatments, root growth was improved, the number of harvested plants was increased considerably and dry root yield per ha were increased by 29 and 22 %, respectively, compared with control.

  • This study was carried out to investigate the effects of washing times on quality characteristics of chicken breast surimi. The surimi was prepare after 2 (C), 4 (T1) and 6 (T2) times washed with a ratio 6 : 1 distilled water-chicken breast meat. The moisture and crude protein content of T1 and T2 were higher than that of C. The myofibrillay protein and yield of C was higher (p<0.05) than those of T1 and T2. The pH of C was higher (p<0.05) compare to other treatments. The WHC was no significant differences between the all treatments. The shear force of all treatments were tended to higher as washing times increased. The breaking force and deformation value of T2 were lower than other treatments. The $L^{*}$ values in C and $b^{\ast}$ values in T1 were significantly (p<0.05) lower among the treatments group. The hardness and gumminess of T1 was higher (p<0.05) compared to T2. The springiness of treatments increased as washing times increased. The sensory score of surimi made from chicken breast meat was not affected by the washing times.

  • Rice flour milled from spray-washed rice was stored at $5^{\circ}C$, $20^{\circ}C$, and $35^{\circ}C$ for 4 months and changes in flour properties during the storage were investigated. Moisture content of rice flour tended to decrease during the storage, and the reduction in the moisture content was higher at higher storage temperature. Compared to dry-milled rice flour, lightness of the rice flour milled from spray-washed rice was slightly higher and tended to increase slightly during the storage. Rapid Visco-Aanlyzer (RVA) peak viscosity of rice flour milled from spray-washed rice was higher throughout the storage period, compared to dry-milled rice flour. The RVA peak viscosity was lower in the order of rice flour stored at $5^{\circ}C$, $20^{\circ}C$, and $35^{\circ}C$. Little changes in setback viscosity were observed in rice flour stored at $5^{\circ}C$ and $20^{\circ}C$, while an increase in the setback viscosity was found in rice flour stored at $35^{\circ}C$. Total bacteria count was consistently lower in the rice flour milled from spray-washed rice, suggesting that spray-washing prior to milling could lower microbial growth of rice flour during storage.
