The previous control point surveying. being standardized by trigonometric point which hasn't: been unified in the whole country and producing put into operation through complex calculation process, has many- problems about accurate results and economic side. Because most of trigonometric points that standardize a present surveying are in situation in top of the mountain, there are man)- difficulties in solving sight problems. Since trigonometric points are far away from one another, Differences are created because of limitation of point distance. observatory network construction and distribution of error In the information age. the study about acquiring three dimension surveying information that uses GPS has been processed as fast as acquiring topography information is getting important gradually. For utilizing GPS in surveying work. deciding transformation 7-Parameters that changes data about location information which is received by GPS receiver is important. In this study-. It is decided transformation 7-Parameters that can be used in ka-pyoung area by using GPS sun-el-ing production that had put into operation.

Purpose: For recurrent esophageal cancer after primary definitive radiotherapy, no general treatment guidelines are available. We evaluated the toxicities and clinical outcomes of re-irradiation (re-RT) for recurrent esophageal cancer. Materials and Methods: We analyzed 10 patients with recurrent esophageal cancer treated with re-RT after primary definitive radiotherapy. The median time interval between primary radiotherapy and re-RT was 15.6 months (range, 4.8 to 36.4 months). The total dose of primary radiotherapy was a median of 50.4 Gy (range, 50.4 to 63.0 Gy). The total dose of re-RT was a median of 46.5 Gy (range, 44.0 to 50.4 Gy). Results: The median follow-up period was 4.9 months (range, 2.6 to 11.4 months). The tumor response at 3 months after the end of re-RT was complete response (n = 2), partial response (n = 1), stable disease (n = 2), and progressive disease (n = 5). Grade 5 tracheoesophageal fistula developed in three patients. The time interval between primary radiotherapy and re-RT was less than 12 months in two of these three patients. Late toxicities included grade 1 dysphagia (n = 1). Conclusion: Re-RT of recurrent esophageal cancer after primary radiotherapy can cause severe toxicity.

<B>Graphic Abstract</B> <P>Spot the mass of peptides: A label-free protein kinase assay that uses secondary-ion mass spectrometric imaging has been demonstrated with peptide-conjugated gold nanoparticles (AuNPs). With detection of the mass change of peptide substrates in a kinase reaction, AuNP-enhanced peptide signals enabled the assaying of both the protein kinase and its inhibition by chemical imaging of peptide substrates on a surface (see picture). <img src='wiley_img/14337851-2007-46-36-ANIE200701418-content.gif' alt='wiley_img/14337851-2007-46-36-ANIE200701418-content'> </P>

<P>Abstract</P><P><B><I>Background/Aim:</I></B> Little is known about the patterns of treatment failure following definitive chemoradiotherapy (CCRT), especially in esophageal squamous cell carcinoma (SCC). We evaluated definitive CCRT failure patterns and determined the predictive factors for treatment response in esophageal SCC. <B><I>Methods:</I></B> We evaluated 136 consecutive patients with esophageal SCC treated with definitive CCRT. We evaluated the factors associated with complete remission (CR) after CCRT and analyzed the pattern of treatment failure of recurred patients and incomplete remission patients. The failures were categorized as either within (locoregional failure) or outside the radiation field (out-field failure). <B><I>Results:</I></B> Fifty-seven patients achieved CR after CCRT. Consolidation chemotherapy was significantly associated with CR. Only 4 (7.0%) patients had CR after CCRT in patients with M1a node (Celiac or subclavian lymph nodes involvement by 6th AJCC). During follow-up, 74 patients (54.4%) experienced locoregional failure, 26 (19.1%) out-field failure, and 35 (25.7%) no failure. Esophageal obstruction prior to CCRT, residual tumor according to the first follow-up endoscopy, and poor follow-up computed tomography responses were significantly associated with locoregional failure. <B><I>Conclusion:</I></B> Approximately 70% of treatment failures were local failures. Future therapeutic strategies need to focus on improving local control to increase treatment outcomes of CCRT.</P><P>© 2014 S. Karger AG, Basel</P>
Hydrogen peroxide detoxification is a key mechanism for growth of ammonia-oxidizing archaea

<P>Ammonia-oxidizing archaea (AOA), that is, members of the Thaumarchaeota phylum, occur ubiquitously in the environment and are of major significance for global nitrogen cycling. However, controls on cell growth and organic carbon assimilation by AOA are poorly understood. We isolated an ammonia-oxidizing archaeon (designated strain DDS1) from seawater and used this organism to study the physiology of ammonia oxidation. These findings were confirmed using four additional Thaumarchaeota strains from both marine and terrestrial habitats. Ammonia oxidation by strain DDS1 was enhanced in coculture with other bacteria, as well as in artificial seawater media supplemented with alpha-keto acids (e.g., pyruvate, oxaloacetate). alpha-Keto acid-enhanced activity of AOA has previously been interpreted as evidence of mixotrophy. However, assays for heterotrophic growth indicated that incorporation of pyruvate into archaeal membrane lipids was negligible. Lipid carbon atoms were, instead, derived from dissolved inorganic carbon, indicating strict autotrophic growth. alpha-Keto acids spontaneously detoxify H2O2 via a nonenzymatic decarboxylation reaction, suggesting a role of alpha-keto acids as H2O2 scavengers. Indeed, agents that also scavenge H2O2, such as dimethylthiourea and catalase, replaced the alpha-keto acid requirement, enhancing growth of strain DDS1. In fact, in the absence of alpha-keto acids, strain DDS1 and other AOA isolates were shown to endogenously produce H2O2 (up to similar to 4.5 mu M), which was inhibitory to growth. Genomic analyses indicated catalase genes are largely absent in the AOA. Our results indicate that AOA broadly feature strict autotrophic nutrition and implicate H2O2 as an important factor determining the activity, evolution, and community ecology of AOA ecotypes.</P>
