The purpose of this study was to examine the effects of the literary approach using a game strategy on young children`s phonological awareness and writing abilities. The subjects were selected from two classes of ``H`` and ``M`` Kindergarten in G city. The research tools used were the Phonological Awareness Ability Test, which was corrected by Jo, Kim, and Jeong(2006) and used to measure young children`s phonological awareness abilities, and Lindberg(1987)`s Kindergarten Writing Assessment which was adapted and used by Noh(1994) in order to assess writing abilities. The literary approach activity using a game strategy used in this study resulted in an improvement in young children`s phonological awareness abilities and writing abilities. These results suggest that these activities are valuable tools and can be applied successfully in the childhood education field as teaching aids.

Rice (Oryza sativa L.) is important crop as a staple carbohydrate sources and was regarded as domesticated in Asia region. The seed dormancy is one of the domesticated traits, and this character allows that plants survive in various environment. The degree of dormancy have been targeted for controling in breeding program while weak dormancy cause pre-harvest sprouting contrary to the nonuniform seed germination by strong dormancy. In this study, we surveyed the variation of germiability in diverse rice genetic resources including japonica and indica ecotype. Overall, the degree of seed dormancy of rice germplasm was distinguished into four groups and admixed types; first group(G-1) included accessions revealing high germiability, the accessions of second group(G-2) acquired the high germiability by after-ripening process, third group(G-3)’s accessions showed high germiability after dormancy breaking process and the accessions of last group(G-4) maintained the low germiability in spite of the dormancy breaking process. Among the 51 japonica accessions G-1, G-2, G-3 and G-4 included 15, 15, 11 and 10 accessions, respectively, and among 40 indica accessions, G-1, G-2, G-3 and G-4 groups included 15, 15, 9 and 1 accessions, respectively. Based on these primary test, we plan to detail examine the seed germiability and survey the genetic factors affecting the degree of germiability in representative accessions of each group

Disinfection of Penicillium-infected Wheat Seed by Gaseous Chlorine Dioxide
Jeon, Young-ah,Lee, Ho-sun,Lee, Young-yi,Lee, Sokyoung,Sung, Jung-sook The Korean Society of Plant Pathology 2015 식물병연구 Vol.21 No.2
Seeds of wheat (Triticum aestivum L. cv. Olgeurumil) were infected with Penicillium sp. at mean infection rate of 83%. Penicillium sp. was detected in endosperm with bran but not in embryo. Gaseous chlorine dioxide ($ClO_2$) effectively inhibited growth of Penicillium sp. at concentration of 5 to $20{\mu}g/ml$. As treatment duration was extended from 1 to 3 h, growth of Penicillium sp. was completely suppressed even at $10{\mu}g/ml$. There was no significant reduction in the incidence of Penicillium sp. at 30% relative humidity (RH). However, the incidence of Penicillium sp. was 27.7% at 50% RH, further those were 3.5% and 0.2% at 70% and 80% RH, respectively. Seed germination was not affected by $ClO_2$ treatment at all the RH conditions. Water-soaked seeds (30% seed moisture content) showed a drastic reduction in the incidence of Penicillium sp. when treated at more than $10{\mu}g/ml$ of $ClO_2$. The incidences of Penicillium sp. were 3.3, 1.8 and 1.2% at 10, 15 and $20{\mu}g/ml$, respectively. The incidence of Penicillium sp. in dry seeds with 9.7% seed moisture content did not reduce when treated with 5 and $10{\mu}g/ml$ at 50% RH although it tended to decrease as $ClO_2$ concentration increased to $20{\mu}g/ml$. Seed germination was not affected by $ClO_2$ treatment at the tested concentrations. These results indicated that gaseous $ClO_2$ was effective disinfectant to wheat seeds infected with Penicillium sp. and that the effectiveness of $ClO_2$ strongly increased when moisture content around or inside of the seed was increased.
Emergency Detection System using PDA based on Self-response Algorithm
Ah-young Jeon,Jun-mo Park,전계록,Soo-young Ye,김재형 한국전기전자재료학회 2007 Transactions on Electrical and Electronic Material Vol.8 No.6
The aged are faced with increasing risk for falls. The aged have more fragile bones than others. When falls occur, it is important to detect this emergency state because such events often lead to more serious illness or even death. A implementation of PDA system, for detection of emergency situation, was developed using 3-axis accelerometer in this paper as follows. The signals were acquired from the 3-axis accelerometer, and then transmitted to the PDA through a Bluetooth module. This system can classify human activity, and also detect an emergency state like falls. When the fall occurs, the system generates the alarm on the PDA. If a subject does not respond to the alarm, the system determines whether the current situation is an emergency state or not, and then sends some information to the emergency center in the case of an urgent situation. Three different studies were conducted on 12 experimental subjects, with results indicating a good accuracy. The first study was performed to detect the posture change of human daily activity. The second study was performed to detect the correct direction of fall. The third study was conducted to check the classification of the daily physical activity. Each test lasted at least 1 min. in the third study. The output of the acceleration signal was compared and evaluated by changing various postures after attaching a 3-axis accelerometer module on the chest. The newly developed system has some important features such as portability, convenience and low cost. One of the main advantages of this system is that it is available at home healthcare environment. Another important feature lies in its low cost of manufacture. The implemented system can detect the fall accurately, so it will be widely used in emergency situations.
