Ulsan was selected as an industrial and industrial city, a leading city of Korean economic development in the 1960s, and it was rapidly changed social environment with the influx of many labor population. This change has had a great impact on the traditional customs of the region, and the traditional intangible culture has disappeared or disappeared, which requires urgent protection of intangible cultures compared to other regions. This study suggests the current situation to restore the agricultural music made up of the three-time customs recorded in the 1930s in Ulsan Dali area. The research method is literature research and field research. First, the literature analyzes the farming music in connection with the farming work performed in the Ulsan Dali area in 1936, and secondly, The field survey was based on the current situation of restoring farm music at the Nam-gu Cultural Center in Ulsan. The results of the research were observed in the Ulsan area, which has disappeared rapidly. In addition, it revealed the status of being handed down from 'Kim Dal-oh', a traditional farmer who worked at Ulsan Cultural Center, to 'Kim Se-ju', who is trying to restore the farm music.

Liquid chromatography/atmospheric pressure chemical ionization-mass spectrometry (LC-APCI-MS) has been used for the determination of sulfonamides in meat. Five typical sulfonamides were selected as target compounds, and beef meat was selected as a matrix sample. As internal standards, sulfapyridine and isotope labeled sulfamethazine (${13}^C_6$-SMZ) were used. Compared to the results of recent reports, our result have shown improved precision to a RSD of 1.8% for the determination of sulfamethazine spiked with 75 ng/g level in meat.

Antifungal metabolites were isolated from a culture of Pseudomonas aurantiaca IB5-10. Chemical structures of the metabolites were elucidated as phenazine-1-carboxylic acid (PCA; 1), 2-hydroxyphenazine (2-OH-PHZ; 2), and cyclo-(L-Pro-L-Val; 3), respectively, based on spectroscopic methods. Among them, 3 was isolated for the first time from this strain. The antifungal activities of 1-3 were evaluated against a variety of plant pathogens. To the best of our knowledge, the antifungal activities of 3 against plant fungal pathogens have been evaluated for the first time in this work. PCA (1) showed the most potent antifungal activities against Phytophthora capsici, Rhizoctonia solani AG-1(IA), and Pythium ultimum with MICs (${\mu}g/ml$) of less than 1.0, 1.3, and 2.0, respectively. On the other hand, 2-OH-PHZ (2) showed potent antifungal activity against R. solani AG-1(IA) with the MIC (${\mu}g/ml$) of 2.0, whereas it showed moderate antifungal activity against P. ultimum with the MIC (${\mu}g/ml$) of 50.0. In addition, 3 showed antifungal activity against only R. solani AG-1(IA).

The standard uncertainties of two different approaches using the same data set are compared and evaluated using an example of gravimetric standard gas preparation. It is shown that the correlation between input quantities should be taken into account for the proper evaluation of uncertainty resulting from random effects.
