Residual materials such as veterinary drugs, environmental contaminants, and pesticides are affecting food safety. High resolution techniques and quality controls are needed to analyze these materials from part per million to part per trillion quantities in food. In order to achieve quality results, standardized methods and techniques are required. Our laboratories were prepared to obtain a certificate of accreditation for ISO/IEC 17025 in the analytical criteria of animal drugs, dioxins, pesticides, and heavy metals. ISO together with IEC has built a strategic partnership with the World Trade Organization with the common goal of promoting a free and fair global trading system. ISO collaborates with the United Nations Organization and its specialized agencies and commissions, particularly those involved in the harmonization of regulations and public policies including the World Health Organization and CODEX Alimentarius for food safety measurement, management and traceability. Our goal was to have high quality analysts, proper analytical methods, good laboratory facilities, and safety systems within guidelines of ISO/IEC 17025. All staff members took requirement exams. We applied proficiency tests in the analysis of veterinary drugs (nitrofuran metabolites, sulfonamide and tetracyclines), dioxins, organophosphorus pesticides, and heavy metals (Cd, Pb, As) to the Food Analysis Performance Assessment Scheme (FAPAS) at Central Science Laboratory, Department for Environment Food and Rural Affairs (DEFRA), England. The results were very satisfactory. All documents were prepared, including system management, laboratory management, standard operational procedures for testing, reporting, and more. The criteria encompassed the requirements of ISO/IEC 17025:1999. Finally, the Korea Laboratory Accreditation Scheme (KOLAS) accredited our testing laboratories in accordance with the provisions of Article 23 of the National Standards Act. The accreditation will give us the benefit of becoming a regional reference laboratory in Asia.

Safety assessment of 16 sweeteners for the Korean population using dietary intake monitoring and poundage method

Kim, MeeKyung,Lee, Gunyoung,Lim, Ho Soo,Yun, Sang Soon,Hwang, Myungsil,Hong, Jin-Hwan,Kwon, Hoonjeong Informa UK (TaylorFrancis) 2017 Food additives & contaminants. Part A. Chemistry, Vol.34 No.9

<P>A sweetener is a food additive that imparts a sweet taste to food products. Sweeteners have been increasingly used in Korea since the approval of sodium saccharin and d-sorbitol in 1962. Unlike food contaminants, humans are exposed to food additives only through the consumption of processed food products. For exposure assessments of sweeteners, the dietary intakes of food products containing acesulfame-K, aspartame, saccharin-Na, and sucralose were determined, and the resulting calculated estimated daily intake (EDI) values were compared directly with each additive's ADI. The poundage method was used to calculate the daily intake per capita for 12 additional sweeteners, such as lactitol, for which appropriate analytical methods for food products do not exist. The risk, as evaluated by comparing the EDI with the ADI, was determined to be 2.9% for acesulfame-K, 0.8% for aspartame, 3.6% for saccharin-Na, 4.3% for steviol glycosides, and 2.1% for sucralose. No hazardous effect was predicted for the other 11 sweeteners, including lactitol.</P>

Unequal Geographic Distribution of Life Expectancy in Seoul

Kim, Sangmi,Yi, Seonju,Kim, Meekyung,Kim, Bokyung,Lee, Hwayoung,Jeon, Taekryeon,Cho, Youngtae SAGE Publications 2015 Asia-Pacific journal of public health Vol.27 No.2

<P>This study examined life expectancies in 25 <I>gu</I>s, administrative districts of Seoul, the capital of Korea, by gender in 1995, 2002, and 2008 to explore trends in mortality inequality among areas. The authors constructed single-decrement life tables and employed between-group variance, the Theil index, and mean log deviation to measure absolute and relative disparities in life expectancy among areas during the periods 1995-2002 and 2002-2008. It was found that life expectancy gaps between <I>gu</I>s have widened in absolute and relative terms in both genders over the decade, and that this pattern was particularly dramatic in females after 2002. This increasing gap could be attributable to the more negative health impact on females since the late 1990s stemming from the economic crisis, eventually reflected in their places of residence. Thus, a social buffer system to narrow the health gap between geographic areas and social classes must be established.</P>

Determination of phthalates in raw bovine milk by gas chromatography/time-of-flight mass spectrometry (GC/TOF-MS) and dietary intakes

Kim, Meekyung,Yun, Seon Jong,Chung, Gab-Soo Informa UK (TaylorFrancis) 2009 Food additives & contaminants. Part A. Chemistry, Vol.26 No.1

<P>Low levels of phthalates, including di(2-ethylhexyl) phthalate (DEHP), in raw bovine milk were determined using gas chromatography/time-of-flight mass spectrometry (GC/TOF-MS). A fast and convenient process of sample treatment combined with TOF-MS analysis (medium resolution >5000), yielded good recoveries (85-125%) and low limits of detection (<0.002 mg kg(-1)). The most commonly used phthalate, DEHP, was found in 15 out of 30 samples monitored in this study. DEHP concentrations in raw milk ranged from not detected to 0.154 mg kg(-1), and the mean concentration was 0.057 mg kg(-1). The dietary intake of DEHP was about 0.004 mg kg(-1) body weight day(-1) if a child (24 months, 13 kg body weight) drinks 1 L day(-1) of milk that contains the mean concentration of DEHP found in raw milk. The estimated dietary intake corresponded to 8% of the European Union tolerable daily intake (TDI) of 0.05 mg kg(-1) body weight day(-1). Dimethyl phthalate (DMP) and di-n-butyl phthalate (DBP) were found from two and 20 samples, respectively, at low levels. Diethyl phthalate (DEP), butylbenzyl phthalate (BBP), and di-n-octyl phthalate (DnOP) were not found in any of the samples.</P>

Decreasing concentrations of PCDD/Fs in pork based on Korean monitoring in years 2002 and 2005

Kim, Meekyung,Choi, Si Weon,Kim, Dong-Gyu Informa UK (TaylorFrancis) 2008 Food additives & contaminants. Part A. Chemistry, Vol.25 No.10

<P>The congener-specific profiles of PCDD/Fs in domestic and imported pork monitored in South Korea in years 2002 and 2005 were compared. Total concentrations of PCDD/Fs decreased from 2002 to 2005, but displayed a similar pattern of congeners. In neither 2002 nor 2005 were either 2,3,7,8-TCDD or 2,3,7,8-TCDF detected. The mean concentrations of PCDD/Fs in domestic and imported pork were 8.29 pg g(-1) fat from 106 samples in 2002 and 4.03 pg g(-1) fat from 90 samples in 2005. However, the contribution of PCDDs increased about four times with respect to toxic equivalent (TEQ) level and about 1.5 times in terms of concentration in the monitoring results from 2005 compared with 2002, and the PCDF contribution decreased substantially. This suggests that the main source of dioxins in pork probably changed to a larger portion coming from animal feeds than environmental sources of exposure. The estimated human intakes of PCDD/Fs originating from pork in the South Korean diet were calculated as 0.029 and 0.019 pg TEQkg(-1) body weight day(-1) for the upper bound exposure in 2002 and 2005, respectively. The values represent low intakes when compared with the both Korean tolerable daily intake (TDI) (4 pg TEQkg(-1) body weight day(-1)) and World Health Organization TDI (1-4 pg TEQkg(-1) body weight day(-1)).</P>

서미경(Meekyung Seo),송지수(Ji-Soo Song),신터전(Teo Jeon Shin),현홍근(Hong-Keun Hyun),김정욱(Jung-Wook Kim),장기택(Ki-Taeg Jang),이상훈(Sang-Hoon Lee),김영재(Young-Jae Kim) Asia association of Disability and Oral health 2018 International Journal of Disability and Oral Healt Vol.14 No.1

Williams syndrome (WS) is a rare congenital disorder which is caused by microdeletion of approximately 1.6 MBP from the long arm of chromosome 7 at 7q11.23. It is characterized by cardiovascular anomalies, elfin face and mental retardation. The most typical oral signs in patient with WS are hypodontia, reduced mesio-distal dimensions both in the primary and permanent teeth, macroglossia, excessive interdental spacing, enamel hypoplasia and enamel hypomineralization. The majority of children with WS have mild to moderate mental retardation, generalized anxiety disorder, hyperactivity disorder and sensitivity to sounds. The purpose of this presentation is to describe dental treatment for a child with WS. A 9-year-old boy diagnosed with WS had caries on his first permanent molars. Because of the poor cooperation, these teeth were filled temporarily with glass ionomer, and treatment under general anesthesia was planned. Under general anesthesia, caries treatment of first permanent molar and extraction of primary molar was successfully performed and there was no postoperative complications related to general anesthesia. Open bite, hypodontia, excessive dental space, enamel hypoplasia, enamel hypomineralization were observed which were characteristic in WS.

수확기간별 배추의 가공처리에 따른 total glucosinolates함량변화

김미경(Meekyung Kim),홍은영(Eunyoung Hong),김건희(Gun-Hee Kim) 한국원예학회 2010 원예과학기술지 Vol.28 No.4

6-7월, 8-9월, 10-11월, 12-4월(2007년) 및 5월(2008년)에 수확한 신선배추, 절임공정 및 김치 제조과정을 거친 배추를 겉잎과 속잎 부위로 나누어 anion-exchange column을 통과시키고 아세톤 침전법을 사용하여 제조한crude myrosinase로 반응시켜 total glucosinolates 함량을 분석하였다. 신선배추의 경우 6-7월 신선배추의 total glucosinolates 함량이 가장 높은 함량을 나타내었으며, 모든 수확기간에서 속잎보다 겉잎이 대체로 높은 것으로 나타났다. 가공처리 한 배추의 total glucosinolates 함량을 분석 한 결과, 절임배추의 경우 8-9월 절임배추에서 가장 높게 나타났으며, 5월 절임배추의 경우 다른 수확기간에 비해 낮은 함량인 것으로 분석되었다. 부위 별 절임배추의 total glucosinolates 함량은 6-7월 절임배추와 8-9월 절임배추의 경우 겉잎의 함량이 속잎의 함량보다 높은 것으로 분석된 반면, 10-11월, 12-4월 및 5월 절임배추에서는 속잎의 함량이 높은 것으로 확인 되었다. 배추김치의 경우 6-7월, 8-9월 김치의 total glucosinolates 함량은 비교적 높은 함량을 나타내었으며, 5월 김치의 경우 다른수확시기에 비해 낮은 함량인 것으로 측정되었다. 배추김치의 부위별 total glucosinolates함량은 5월 배추김치의 경우속잎의 함량이 겉잎의 함량보다 높게 분석된 반면, 6-7월, 8-9월, 10-11월 배추김치의 경우 겉잎의 함량이 속잎의 함량보다 높은 것으로 분석되었다. 모든 수확기간에서 신선배추의 total glucosinolates 함량보다 가공 처리한 절임배추, 배추김치의 total glucosinolates 함량이 감소하는 경향을 볼수 있었다. 이러한 분석 결과는 배추의 total glucosinolates 함량이 수확기간, 부위 및 가공처리에 따라 영향을 받는 것으로 사료되며, total glucosinolates 함량에 영향을 줄 수 있는 배추의 부위, 품종, 재배방법 및 재배환경(pH, 온도, 기후, 토양 등)은 고려 되어야 한다고 판단된다. This study was carried out to investigate the level of total glucosinolates in different parts (outer and inner part) of fresh, salted Chinese cabbage (Brassica campestris L. ssp. Pekinensis) and Kimchi at different harvesting periods (June-July, August-September, October-November, December-April, and May). For determination of total glucosinolates, Chinese cabbage was used for analytical sample preparation, provided with an anion exchanges column and measured by UV-visible Spectrophotometer. The fresh Chinese cabbage (FCC) that was harvested in June-July contained the highest level of total glucosinolates and was higher in outer part than inner part in all harvesting periods. The salted Chinese cabbage (SCC) that was harvested in May contained the lowest level of total glucosinolates. Total glucosinolates level of SCC in outer part was higher in June-July and August-September. The manufactured Kimchi (K) using harvested Chinese cabbage in June-July and August-September contained the highest level of total glucosinolates while that harvested in May contained the lowest level. The level of total glucosinolates in different parts was higher in inner part than outer part in all harvesting periods except for May. In all harvesting times, the level of total glucosinolates of FCC was higher than processed Chinese cabbage (SCC and K). Based on these results, levels of total glucosinolates are influenced by harvesting periods, parts and processing conditions of Chinese cabbage.
