  • Citrus farming become one of highly potent area for the farmer s income in the Asia region. Because of its favorable taste and distinctive aroma, attractive color, and nutritional values, market demand has increased steadily along with the income increases in the region. However, realization of the potent have been constrained due to poor orchard management, frequent occurrences of pest and diseases, and a high cost in production besides of the market failures. Cutting down of production cost should be an operational goal to obtain mope profit where marketing structure has yet been underdeveloped. The objective of this study was to provide a comparative information to those program efforts of searching comparative advantage in production. For the three countries, reduction of labor cost by reduction of chemical application frequency was recommended while pursuing further mechanization in those operation such as in pruning, harvesting and pest control. Adoption of the IPM (integrated pest management) will be useful to reduce the number of spraying chemicals with changed knowledge and attitude of the farmers.

  • Comparative study on a low cost sustaining driver with single and dual path energy recovery circuits for plasma display panels (PDPs) is shown in this paper. The cost of PDPs has been still high and about half of the cost has been occupied by driving circuit. A simple sustaining driver is proposed to reduce the cost and size of driving circuit. The proposed driver has small number of devices and reactive components and there are two methods for charging and discharging PDPs such as single and dual path energy recovery circuits. A comparative research on two-types of energy recovery path is practiced to evaluate performance. As a result, the dual energy recovery path circuit has low power consumption, low surge current and high performance. To verify those results, experiment will be shown with 42-inch HD panel.

  • This study investigates the conditions under which the compensation effect occurs in advertising, focusing on the influence of warmth messages on consumer perceptions and responses. By comparing single-ad and comparative ad exposure contexts, the research reveals how warmth messages affect perceived brand competence and the intention to like ads. High warmth messages, when viewed in a comparative ad setting, lead to lower perceived brand competence compared to a single-ad setting, emphasizing the need for strategic message placement in competitive environments. The study further explores how consumers' construal levels-whether considering near-future or distant-future purchase decisions-moderate these effects. The negative impact of high warmth messages on perceived competence is amplified in a comparative context at low construal levels, while high construal levels mitigate this negative impact. These results provide both theoretical and practical insights, highlighting the importance of ad context and construal level in advertising strategies.

  • Currently, selecting comparative standard land parcels for evaluating individual public land price is done by cadastral officers manually. Due to the amount of land parcels to be evaluated in a short period of time and the subjective methodology adopted, the results are not satisfactory and affect the final individual public land price evaluation. This study aims to develop, implement, and test a new automatic and objective methodology for selecting comparative standard land parcels using spatial multi criteria decision making rules. We conclude that spatial multiattribute decision making rules perform very well in this kind of problem and especially an AHP based method is highly appropriate for this purpose.

  • This research involved the conducting of an experiment in order to determine the relative effectiveness of constructivist science education when integrated with art experience and constructivist science education for young children. Forty-one children of five years of age in two daycare center classes were assigned to experimental and comparative groups. The experimental and comparative group participated in 15 units. The experimental group participated in science education integrated with art experience, while the comparative group participated in science education. The analysis of covariance revealed significant differences between the mean scores of the two groups on the posttests for science process skills and attitudes. This indicates that the children in the experimental group performed significantly better on the tests than the children in the comparative group. The results of this study suggest that incorporating constructivist science education activities with art experience are good activities for developing young children's science process skills and attitudes.

  • Most neuroblastoma cells have chromosomal aberrations such as gains, losses, amplifications and deletions of DNA. Conventional approaches like fluorescence in situ hybridization (FISH) or metaphase comparative genomic hybridization (CGH) can detect chromosomal aberrations, but their resolution is low. In this study we used array-based comparative genomic hybridization to identify the chromosomal aberrations in human neuroblastoma SH-SY5Y cells. The DNA microarray consisting of 4000 bacterial artificial chromosome (BAC) clones was able to detect chromosomal regions with aberrations. The SH-SY5Y cells showed chromosomal gains in 1q12~ q44 (Chr1:142188905-246084832), 7 (over the whole chro-mosome), 2p25.3~p16.3 (Chr2:18179-47899074), and 17q 21.32~q25.3 (Chr17:42153031-78607159), while chromosomal losses detected were the distal deletion of 1p36.33 (Chr1:552910-563807), 14q21.1~q21.3 (Chr14:37666271-47282550), and 22q13.1~q13.2 (Chr22:36885764-4190 7123). Except for the gain in 17q21 and the loss in 1p36, the other regions of gain or loss in SH-SY5Y cells were newly identified.
