The ginseng growth-promoting bacterium Pseudomonas fluorescens KGPP 207 synthesized indole-3- acetic acid (IAA) from L-tryptophan, indole-3-pyruvic acid (IPyA), and indole-3-acetaldehyde (IAAld), but not from indole-3-acetamide (lAM) and other intermediates of various IAA biosynthetic pathways in the experiment with indole compound supplemented cell suspensions. TLC, HPLC, and GC-MS analyses revealed the presence of IPyA, indole-3-ethanol, indole-3-lactic acid and its methyl ester, IAA and its methyl, and ethyl esters in the culture supernatant of the bacterium. IAAld was detected in the supernatant using sodium bisulfite and TLC. The results indicate that unlike gall-forming bacteria which can synthesize IAA by lAM, the indole-3-pyruvic acid pathway is the route for IAA biosynthesis in this beneficial strain of P. fluorescens.

Not all parents are skilled in scaffolding their young children's numeracy learning. The present study investigated the effectiveness of a parent training program in promoting Filipino young children's number sense via card game playing at home. Participants were 161 young children and their parents; families were of a relatively low socioeconomic status. During the 10-week intervention period, parents in the experimental group received training on how to use number game cards to help their children acquire various numeracy concepts; parents in the control group received no special instructions. Children in the experimental group showed greater improvements in their performance on six number sense tasks (namely numeral identification, object counting, rote counting, missing number, numerical magnitude comparison, and addition) over the intervention period than did children in the control group. Findings of the present study suggest that providing simple training to parents on strategies for fostering their young children's number sense at home is important for giving children a good early start in basic number knowledge.

Seismic retrofitting technologies have been paid attention to structural engineers for rehabilitations of existing building structures vulnerable to seismic loading conditions. This paper introduces the traditional strengtheing method applying externally-bonded steel frames to column and beam elements, and compares with the improved scheme using the frames with additional energy dissipation systems. Throughout experimental studies, it was observed that the method can be effective for promoting the seismic performance of seismic force-resisting systems by guaranteeing strong column-weak beam mechanism. Compared to the traditional manner, it was found that the new scheme can be more efficient for confirming capacity design concept, while energy dissipation systems can provide additional damping effects corresponding to lateral deformation which occurs at seismic force-resisting systems exposed to seismic excitations.

A study on relation of angiogenesis and blood stagnation in cancer was done, and the results were as follows. 1. Angiogenesis is a sequence of vascular proliferation and accomplished by regulation of anti-angiogenesis factor and indicating factor. These factors are secreted in the course of blood coagulation, inflammation, and regeneration. 2. Angiogenesis in cancer is a important action in growth of tumor and metastasis because it supply oxygen and nutrition. 3. The complicated processes, for example, platelet coagulation, action of coagulator factor & dissolution factor and interaction of variety factors are related to blood stasis and promoting blood circulation to remove blood stasis in oriental medicine. 4. Promoting blood circulation to remove blood stasis is expected to suppress angiogenesis, and we expect advanced study will be accomplished in future.

During cancer progression, bone marrow derived myeloid cells, including immature myeloid cells and macrophages, progressively accumulate at the primary tumour site where they contribute to the establishment of a tumour promoting microenvironment. A marked infiltration of macrophages into the stromal compartment and the generation of a desmoplastic stromal reaction is a particular characteristic of pancreatic ductal adenocarcinoma (PDA) and is thought to play a key role in disease progression and its response to therapy. Tumour associated macrophages (TAMs) foster PDA tumour progression by promoting angiogenesis, metastasis, and by suppressing an anti-tumourigenic immune response. Recent work also suggests that TAMs contribute to resistance to chemotherapy and to the emergence of cancer stem-like cells. Here we will review the current understanding of the biology and the pro-tumourigenic functions of TAMs in cancer and specifically in PDA, and highlight potential therapeutic strategies to target TAMs and to improve current therapies for pancreatic cancer.

Learner-centered approach has been a recent research focus in the second language acquisition, but few studies have dealt with how to develop learner autonomy, particularly in a computer-assisted language learning environment. The paper first illustrates the importance of promoting learner autonomy in the EFL context and elaborates the three main factors contributing to its development. Then it focuses on how the CALL research project promotes autonomous learning through a small-scale study in Gyeongju University. Both quantitative and qualitative methods have been employed to examine whether in the CALL project learners exercise control over their own learning and evaluate the outcome. The results indicate that due to a flexible syllabus, highly motivating research topics and the network-assisted environment, learners do take responsibility for most aspects of learning and thus the CALL project proves to be a promising approach for autonomous learning.
