We estimate the economic benefit of weather modification (precipitation enhancement and fog dissipation) by assuming its operation for the considered regions. Based on the statistical data, the economic benefit of the virtually operational precipitation enhancement experiments for the Andong and Imha basins, where the natural precipitation is relatively lack in South Korea, is calculated 348 for the water resources, 22,458 for forest fire prevention, and 28,458 million won/year for the drought relief. The benefit of the fog dissipation operation for the Incheon International Airport is estimated 7,365 million won/year for the flight delay due to fog. The calculated ratio of benefit to cost for precipitation enhancement operation for the basins is 14.07, which is comparable to that conducted in other countries.

A case of a 46-year-old Korean male with post-stroke insomnia that induced by intracranial hemorrhage was presented. He was treated with Transcutaneous electric acupoint stimulation (TEAS) at BL62 and KI6 once per a day for 17 days. We recorded the patient's sleep time and time of asleep, and used PSQI-K to assess severity of patient's insomnia symptom. After using TEAS, there was improvement in patient's insomnia severity and the time of sleep. From the result of this case, electrical stimulation at acupoint can may be effective in treating post-stroke insomnia.

Background: Focal adhesion kinase (FAK) and Src are non-receptor tyrosine kinases. FAK and Src play a critical role in inducing malignant transformation in tumor cells. Objectives: We performed immunohistochemical staining for total and phosphorylated forms of FAK and Src, to evaluate the role of FAK and Src in the development of premalignant and malignant skin lesions. Methods: A total of 59 facial skin samples (30 actinic keratoses, 10 Bowen``s diseases, 13 squamous cell carcinomas and six perilesional skins) were immunohistochemically stained for Ki-67, total (t) and phosphorylated (p) form of FAK and Src. Methods: A total of 59 facial skin samples (30 actinic keratoses, 10 Bowen``s diseases, 13 squamous cell carcinomas and six perilesional skins) were immunohistochemically stained for Ki-67, total (t) and phosphorylated (p) form of FAK and Src. Results: Cells positive for t-Src, p-Src-y530, t-FAK and pFAK-s722 were detected in premalignant intra-epithelial lesions (PELs) and squamous cell carcinomas (SCCs), but not in the perilesional skin. There was a tendency towards high correlation between Ki-67 and t-FAK or pFAK-s722, suggestive of the active role of FAK in cell proliferation. Conclusion: Our findings of higher t-Src and p-Src-y530 positive cells in PELs, as compared to SCCs (with higher Ki-67 level), are suggestive of the other role of Src in tumor formation and progression, which requires further investigation.

In an effort to cope with the competitive environment, firms implement advanced manufacturing practices (AMP) such as TQM or JIT. However, previous studies report mixed results about the effectiveness of these practices. The purpose of this study was to examine whether the complementarities between management accounting systems (MAS) and other factors affect the performance of the firm when JIT as AMP is introduced into firms. To achieve research purpose, this study analyzed data from Korean automobile part manufacturers. Results of this study show that there are positive correlations between AMP and MAS that provide information on performance goals and measures. This study has also provided considerable evidence that MAS has an influence on performance goals. These results are consistent with those of previous studies. In addition, this study has shown that complementarities in the usage levels of AMP, the features of the MAS, and the facilitators of learning have positive effects on performance. Implications of the research results can be summarized: (1) When firms adopt AMP, they must be aware that the currently established MAS alone cannot obtain information on non-financial achievements. (2) Providing only management accounting information may have limits in improving the performance of firms, other factors that can promote organizational learning within firms should also be utilized. (3) In designing and implementing MAS, complementarities between the new MAS and AMP must be maintained.

<P>Adenosine 5′-monophosphate-activated protein kinase (AMPK) is an intracellular sensor that can regulate glucose levels within the cell. For this reason, it is well-known to be a target for drugs against diabetes and obesity. AMPK was activated significantly by the hexane extract of barley sprouts. This AMPK activation emerges across the growth stages of the sprout, becoming most significant (3 times above the initial stages) 10 days after sprouting. After this time, the activation decreased between 13 and 20 days post-sprouting. Analysis of the hexane extracts by gas chromatography–mass spectrometry showed that the amounts of policosanols (PCs, which are linear, primary aliphatic alcohols with 20–30 carbons) in the plant dramatically increased between 5 days (109.7 mg/100 g) and 10 days (343.7 mg/100 g) post-sprouting and then levels fell back down, reaching 76.4 mg/100 g at 20 days post-sprouting. This trend is consistent with PCs being the active ingredient in the barley plants. We validate this by showing that hexacosanol is an activator of AMPK. The richest cultivar for PCs was found to be the Daejin cultivar. Cultivars had a significant effect on the total PC content (113.2–183.5 mg/100 g) within the plant up to 5 days post-sprouting. However this dependence upon the cultivar was not so apparent at peak stages of PC production (10 days post-sprouting). The most abundant PC in barley sprout, hexacosanol, contributed 62–80% of the total PC content at every stage. These results are valuable to determine the optimal times of harvest to obtain the highest yield of PCs.</P><P><B>Graphic Abstract</B> <IMG SRC='http://pubs.acs.org/appl/literatum/publisher/achs/journals/content/jafcau/2013/jafcau.2013.61.issue-5/jf3041879/production/images/medium/jf-2012-041879_0004.gif'></P>
