In the present study, a single residual analytical method was developed for pyraclofos. Pyraclofos was analyzed in brown rice, soyabean, green pepper, and mandarin. For pyraclofos, samples were extracted with acetonitrile, concentrated and partitioned with dichloromethane and analyzed with GC/FPD. The limit of quantitation (LOQ) for fosthiazate was 0.1 ng (S/N>10) and method limit of quantitation (MLOQ) was 0.02 mg/kg. Recovery ranged through 78.1%-117.7% at fortification level of 0.02 (MLOQ), 0.2 (10×MLOQ), and 1.0 (50×MLOQ). The coefficient of variation (CV) for both the pesticides was less than 10% regardless of sample types. These results were further confirmed with GC/MS, respectively.

In the present study, a single residual analytical method was developed for fosthiazate. Fosthiazate was analyzed in brown rice, soybean, green pepper, and mandarin. For fosthiazate, samples were extracted with acetonitrile, concentrated and partitioned with dichloromethane and analyzed with GC/FPD. The limit of quantitation (LOQ) for fosthiazate was 0.1 ng (S/N>10) and method limit of quantitation (MLOQ) was 0.02 mg/kg. Recovery ranged through 80.7-111.3% at fortification level of 0.02 (MLOQ), 0.2 (10×MLOQ), and 1.0 (50×MLOQ). The coefficient of variation (CV) for both the pesticides was less than 10% regardless of sample types. These results were further confirmed with GC/MS, respectively.

This study was investigated to determine the residual amounts of boscalid in sedum (Sedum sarmentosum Bunge) using gas-liquid chromatography with electron capture detector (GLC/ECD) and to assess the standard for safe use of boscalid+trifumizole 30 (20+10)% WP. Boscalid is used to control the Botrytis cinerea causing gray mold on sedum. Recovery tests of boscalid in sedum were done by spiking 10 and 50-times of limit of detection (LOD). Recoveries obtained from two concentrations were 95.02% and 88.74%, respectively. The residual amount of boscalid from the sedum harvested 3, 7 and 14 days after 2 and 3-times treatment ranged from 11.68 to 46.20 mg/kg. Because the maxium residue limit (MRL) of boscalid in the sedum is 30.0 mg kg-1, it is proposed for boscalid of boscalid+trifumizole 30 (20+10)% WP to apply 2 times, 7 days before harvest in Korea.

Purpose: The purpose of this study was to identify college student's perception and practice of 'National Cancer Prevention Actions' and the factors that influence the perception and practice. Method: The participants were 310 undergraduates selected by convenience sampling at colleges in Seoul. Instrument was 2014 Survey of Perception and Practice of National Cancer Prevention Actions by National Cancer Center(2014), and has been modified for the purpose of the study. The data were analyzed by t-test, ANOVA and Scheffe test with SPSS 23.0 Windows software. Results: The most recognized action for cancer prevention in college students was "Do not smoke, also avoid smoking smoke"(96.8%) while the most unrecognized was "Get a type B hepatitis vaccination"(58.7%). The most practiced action for cancer prevention in college students was "Sexually as to safe sex"(94.8%) while the most unpracticed was "Exercise five times a week or more, for at least 30 minutes a day"(33.9%). Among general characteristics, participants' age (t=-2.015, p<.05), major (F=3.109, p<.001), and residential type (F=4.959, p<.01) were statistically significant in the recognition of Cancer Prevention Actions and major(F=3.341 p<.05) and residential type(F=3.827, p<.05) were also significant in the practice of Cancer Prevention Actions. Among health characteristics, health concern(F=3.154, p<.05) and education in cancer(t=-3.112, p<.01) showed statistically significant differences in the recognition of Cancer Prevention Actions while health concern(F=7.896 p<.001) and subjective health status(F=9.913, p<.001) showed differences in the practice of Cancer Prevention Actions. Conclusion: These findings showed the gap between the perception and practice of cancer prevention actions. Considering the importance of individual characteristics, it is essential to develop a differentiated cancer prevention education program for college students. Also, nursing intervention program should be developed to raise the alertness of cancer in order to enhance cancer preventive practice.
