A chemical examination of the phenolic compounds in the leaves of Sapium japonicum (Euphorbiaceae) has led to the isolation of eleven phenolic compounds. containing five hydrolysable tannins and six flavonoids. On the basis of chemical and spectroscopic evidences, the structures of these compounds were confirmed to be galic acid(1), 5-O-caffeoyl quinic acid(2), 1-O-galloyl-3, 6-(R)-HHDP-β-n-glucose(coriiagin)(3), 1-O-galloyl-2.4-(R)-DHHDP-βn-glucose (furosin)(4), 1-O-galloyl-2.4-(R)-DHHDP-3.6-(R)-HHDP-β-m-glucose(geraniin)(5), astragalin(6), trifolin(7), afzelin(8), quercetin(9), isoquercitrin(10) and rutin(11). Among them geraniin was the main component.

It has been hypothesized that jobs that have both high psychological demands and low decision latitude("job strain") can lead to musculoskeletal disorder. The objective of this study was to test whether job strain was correlated with the presence of work-related musculoskeletal disorder, especially myofascial pain syndrome(MPS). Information on demographic factors, confounders such as household load and taking care of children or not, and scores for decision latitude, job demand, and social support was obtained by self-administered questionnaire, which had been developed in Korean language, by adopting NIOSH instrument and Extended Karasek Model(16 items). All subjects were also examined by rehabilitation medicine specialists for musculoskeletal disorders. Subjects(n=370) could be categorized into 4 groups, these were, housewives(n=89), shipyard CAD workers(n=89), general female workers(n=79; nurses, insurance counselors, public officials, clerks, etc), and telephone directory assistance operators(n=113). Results from univariate analyses indicated that all demographic factors, all confounders, scores for decision latitude and social support were not associated with the risk of musculoskeletal disorder. However, score for job demand was higher in musculoskeletal disorder cases than others. In subgroup analysis, this association was convinced again, in telephone directory assistance operators. Job strain model showed that the group of telephone directory assistance operators was high-stain group, and OR of musculo skeletal disorder was 2.446(95% C. I. : 1.174, 5.096), when comparing this with the low strain group. In conclusion, job strain is a risk factor for work-related musculoskeletal disorder.

Pesticides were extracted from samples with 70% acetone and methylene chloride in order, and then cleaned up via open-column chromatography apparatus packed with florisil, and finally analyzed simultaneously the organochlorine and pyrethroid pesticides using GC(ECD). An ultra-2 fused silica capillary column was used to separate and identify the products. The resolution between the last isomeric peak of cypermethrin(59.987min) and the first isomeric peak of flucythrinate(60.043min) was not satisfactory. The last isomeric peak of fenvalerate(62.344min) and the first isomeric peak of fluvalinate(62.397min) were overlapped. Recoveries of soybean sample for the most pesticides were 73.3% to 102.4%. Detection limits were between 0.004 and 0.063 ㎍/㎎ when this method was used.

Pesticides were extracted from samples with 70% acetone and methylene chloride in order, and then cleaned up via open-column chromatography apparatus packed with fiorisil, and finally analyzed simultaneously the organophosphorus pesticides using GC/NPD, Ultra-2 and Ultra-1 fused silica capillary columns were used to separate and identify the products. Recovery of most analytes from soybean sample, taken from pesticide residues well, was greater than(80%) for all except(6) analytes. This method can simultaneously determine multiple pesticides with a high degree of accuracy and precision.

N/A Androgen insensitivity syndrome (AIS) is a X-linked disorder of sexual differentiation resulting from defective androgen receptor (AR) function. Androgens are secreted by the testes of 46,XY individuals, but there is loss of target organ response to the hormone. The abnormalities of AR are due to defects in the AR gene, and many mutations causing AIS have been reported since the cloning of AR gene. In this study, we analyzed the AR genes in twelve Korean patients with androgen insensitivity syndrome: 9 patients with complete AIS and 3 patients with partial AIS. DNAs were isolated from patients with AIS, and the coding region of AR gene was amplified by a polymerase chain reaction using 7 pairs of primers (exon B-H). Sequence analysis of the AR gene was performed using direct sequencing and single strand conformational polymorphism (SSCP). The AR gene mutations were identified in 7 out of 12 patients: 6 of 9 patients with complete AIS, and one of 3 patients with partial AIS. Mutations found were as follows: the point mutation (ATT→ACT) at position 680 of exon D, point mutation (TGG→TGC) at position 751 of exon E, point mutation (CAA→TAA) at position 792 of exon F, point mutations (CGC→TGC, GTG→ATG) at position 855 and 866 of exon G, and the deletion of 13 nucleotides (CGTATCATTGCAT) at position 840 of exon G, respectively. To the best of our knowledge, the point mutations found in exon D, exon E, and exon F, and the deletion in exon G have not been observed before. SSCP revealed bands with abnormal mobility in 10 out of 12 patients tested. Mutations were found 5 out of these 10 patients. The other two patients showed no abnormal band on SSCP, but showed mutations by direct sequencing. In conclusion, we have demonstrated the AR gene mutations, including three novel mutations, in Korean patients with AIS, and these abnormalities might be related to the pathogenesis of androgen insensitivity syndrome.

This study was conducted to investigate the timely characteristics of phytoncide in forest trail of Ulsan Metropolitan. Air samples were collected from July to October 2011. The phytoncide were detected and quantified using a Gas Chromatograph Mass Spectrometer(GC/MSD). This study are summarized as follows ; The highest levels of phytoncide concentration of August is higher than other months in Munsu Mt. and Samho Mt.(town mountains). The higher phytoncide emission rates found in the morning and in the evening. The concentration of phytoncide was understanded to be greatly influenced by environment change of day time.

Smart HACCP is a system that can check the monitoring of critical control point (CCP) in real time to implement improvement measures immediately after departure from limit criteria and prevent falsification of data by digitizing handwritten records. In this study, we developed the analysis model for the effectiveness of smart HACCP to compare and analyze with existing HACCP. By introducing of smart HACCP system, the evaluation index value of HACCP effectiveness for HACCP-certificated companies on a small scale increased by 9.25 points, corresponding to 11.52% of increase rate. General HACCP-certificated companies showed 4.52 point and 5.00% of increase rate by introducing of smart HACCP system. Thus, it was confirmed that the introduction of smart HACCP system contributes to the improvement of food safety management and especially it would be more effective for HACCP-certificated companies on a small scale than general HACCP-certificated companies.
