This study describes an analytical method based on LC-MS/MS for the quantitation of 5 fluoroquinolones (Enrofloxacin, Ciprofloxacin, Marbofloxacin, Norfloxacin and Danofloxacin) in meat, and was applied to 230 meat samples for validation. Quantitation was performed based on a matrix-matched calibration to compensate for the matrix effect on the electrospray ionization. Good linear calibrations (R²≥0.998) were obtained for all fluoroquinolones at 6 concentrations of 1~50 ㎍/kg. Satisfied recoveries of all fluoroquinolones were demonstrated in spiked meat at three levels from 10 to 50 ㎍/kg. The recoveries ranged between 75.8~99.2% in beef, 80.1~99.6% in pork and 72.2~99.8% in chicken, respectively. The limits of quantitation (LOQs) for fluoroquinolones ranged from 0.7 to 3.2 ㎍/kg. We also monitored fluoroquinolones residue in the sample (beef 107, pork 71, chicken 52) using LC-MS/MS. Residues of fluoroquinolones which exceeded maximum residue limits (MRL) were not exceed in any of the 230 samples.

국제포경위원회의 상업포경금지 조치에 따라 1986년부터 대한민국에서 포경이 금지되었다. 혼획으로 사망하는 고래의 유통은 계속 이루어져 국제기구 등에서 불법포획 의혹을 제기하기도 했다. 이에 고래 유통 질서를 확립하기 위해 2011년 "고래자원의 보존과 관리에 관한 고시"가 공포되었다. 이후 정부는 고시의 내용을 수 차례 개정하며 유통 질서를 바로 잡고자 했으나, 불법포획 고래의 유통을 막기에는 여전히 부족한 부분이 있다. 본 연구에서는 이력추적 시스템 구축을 통한 고래 유통 질서 확립을 위해 위 고시의 개정을 포함한 관련 제도 개선 사항 등에 대해 연구하였다. 먼저, 불법포획 고래의 시장 진입을 제도적으로 차단하고, 혼획으로 사망한 고래만 유통이 되도록 제도의 개정이 이루어져야 한다. 그리고 불법 유통에 대한 강력한 증거 자료로 사용되는 DNA 데이터베이스를 완벽하게 구성하기 위해 시료 채집 방법과 수사용 시료의 분석 절차 등에 대한 개선이 필요하다. 끝으로 효과적인 유통 이력추적 시스템을 확립해야 한다. 기존의 시스템을 활용하기에는 법률 적용, 시민단체 반대 등 현실적인 어려움이 많기 때문에 블록체인 기술을 활용한 새로운 시스템을 개발하는 것이 보다 타당한 방법으로 여겨진다.

This study aimed to develop a new commercialization model for theindustrialization of head family food as a gentry families' complex food culture product. We tried to develop a head family food and propose a city sightseeing style's head family product by interviews with 'Hakindang' as the center, the head house of the Suwon Baek clan, and Injaegong group in Jeonjoo. Hakindang (in Jeonju) was confirmed as an improved model Korean-style house in the enlightenment period and the twentieth style modern head family as emerging capitalist. Hakindangsupported independence war funds in the Japanese colonial era and was widely known as gate of filial piety in Jeonju. Representative seasonal foods of Hakindang include pan-fried sweet rice cake with flower petals in the spring, hot spicy meat stew and polypus variabilis in summer, hanchae in autumn, and napa cabbage kimchi with salted flatfish seafood in the winter. When parents-in-law had a birthday, there were party noodles, sliced abalone stuffed with pine nuts, brass chafing dish, fish eggs, slices of blilde meat, and matnaji. Daily, there were mainly salted seafood, slices of raw fish, grilled short rib patties, braised fish, baked fish, syruped chestnut, grilled deodeok root, bean sprouts, radish preserved with salt, dongchimi, soy sauce-marinated horseshoe crab, butterbur, perilla seed stew, salted clams, raw bamboo shoot, agar, fried kelp, etc. The most basic virtue of the head family is filial duty, and they developed mosim dining as a representative food of Hakingdang's head family. The mosim menu is composed of 65% carbohydrates, 20% protein, and 15% fat because it is table for parents-in-law like more than 75 years old. The sensory evaluation showed a chewy texture that is easily swallowed.

The Nara Dynasty of Japan lasted from 710 to 784 A.D, which corresponds to the period of the Unified Shilla Kingdom of Korea. The Nara Dynasty enacted the 'Daiho Law and Ordinance' by referring to those of Tang Dynasty of China. Under these legal systems, the Ministries were defined, and foods were used for paying taxes or as currency. The characteristics of the dietary culture in Nara Dynasty were as follows. 1) They obtained food from rice and other grain farming, hunting and fishery. Rice was their main staple and was also used for preparing porridge and brewing wine. 2) Under the influence of Buddhism, meat was prohibited, and milks or dairy products were supplemented for improving malnutritional status. 3) They also used seasonings, spices and sweeteners to enhance the taste and produced medicines by extracting plants, animals and minerals. 4) While chopsticks were made of bamboo, willow, silver, shell, tree or bronze, such utensils as pan earthenware steamer, or charcoal pots were used for preparing meals. 5) Highly qualified utensils, made of porcelains painted with lacguetr, metal, glass, horn and stone, were produced as handcraft art wad developed. 6) Chinese style cousines and cooking methods were popular and various types of preserving techniques like drying or salting were used. Processed cookies were also developed. 7) Although flour was used mainly among noble class people, ordinary people also used it. The royal families ate milk products a lot and even fried foods. 8) One can say that Buddism exerted an influence on Vegetarianism from this era.

This study was conducted to find out the proper ways of implementation of Hazard Analysis Critical Control Point (HACCP) concepts applicable to the current Korean food inspection system. The following recommendations are based on an in-depth review of the Canadian Food Safety Enhancement Program (FSEP), which is one of the leading HACCP programs adapted to the food industry. Since 1997, the HACCP system has been voluntarily applied to meat processing plants in Korea in accordance with the Food Protection Law. But the guidelines are obscure and inadequate to expand to the diversity of food plants, and are therefore only applied to a limited number of plants of small scale enterprise. For these reasons, it is necessary to prepare an enhanced food safety control program focused not only on the HACCP plants but also on the non-HACCP plants. The national program should be the fundamental framework of a food safety control policy enforced by all the relevant authorities. The Prerequiste Program of Canadian Food Inspection Agency and Sanitation Standard Operating Procedures (SSOP) of FSIS are good example programs for the non-HACCP plants. These programs, which are a major part of the HACCP system, could easily be adapted to the Korean food industry. To improve the current HACCP implementation guideline, it is necessary to develop a detailed implementation manual, generic HACCP model, training program, and an audit program.

한국의 개고기 식용은 오랜 역사와 전통을 가지고 있으나 정부는 외국인들이 비난한다고 하여 축산물가공처리법에서 개를 제외시켜서 개고기는 정부의 감시를 받지 않고 유통되고 있다. 국민들의 개고기 식용 합법화요구에 행정부는 동물보호단체의 항의를 이유로 합법화할 수 없다고 하고 있지만 국민의 80％ 정도는 개고기 식용을 찬성하며, 합법화해야 한다고 주장하고, 입법부는 국회의원 20명이 개고기 식용 합법화 법안을 제출하였고, 사법부도 개고기를 식육이라고 판결하였다. 서구인들이 한국의 개고기 식용을 비난하는 내면에는 순수한 동물보호도 있지만 유색인종에 대한 인종차별, 한국에 대한 쇠고기 수출량 증가, 버린 개를 애완견 사료로 사용하기 위한 관심 돌리기, 동물보호 단체의 기금 모금 등의 목적이 있다. 그리고, 정부는 국내 동물보호 관련단체를 앞세워서 개고기 식용 반대 여론을 호도하고, 농림부는 동물보호법을 관할하여 개고기 식용을 반대하는 관련 단체의 편을 들고 있으나 이들 단체는 농민들이 아니다. 나아가 정부는 개고기 식용 문제를 해결할 의지를 보이지 않고, 해결책을 제시하지 못하여 사태를 악화시키고 있다. 그래서 개고기 식용은 위생의 사각지대에 놓여 있고, 개도축 폐기물은 환경을 오염시키고 있다. 이런 문제를 해결하려면 개고기 식용을 합법화시켜서 개고기를 위생적으로 유통시키고, 환경오염을 방지하고, 세수를 증대시키고, 국가의 자존심을 확립해야 한다. 나아가, 농림부는 동물보호법을 환경부 관할로 넘겨서 멸종위기의 동물만 다루고, 정부는 개고기 식용에 대한 정확하고 객관적인 조사와 통계를 바탕으로 신뢰성 있는 정책을 펴야 한다. 그리고 한국의 개고기 음식문화를 세계에 널리 알릴 전담 부서와, 연구소를 설립하고, 민간 기구도 지원하여 발족시켜야 한다. 개고기는 한국을 대표하는 음식으로 가장 세계적인 음식이 될 수 있기 때문이다.

Recently the Korean government has tried to cut down the $PM_{10}$ concentration by the Special Law for Air Quality Improvement. But the concentrations of $PM_{10}$ have exceeded the air quality standard at most monitoring stations. Primary $PM_{10}$ emitted from various sources and emission data have large uncertainty. The biomass burning is one of the major sources of $PM_{10}$ emission. The biomass burning is composed of wood stove usage, meat cooking and agricultural combustion etc.. Activity data and emission factors for the biomass burning are limited, and it is hard to calculate the air pollution emissions from these sources. In this study, we tried to estimate the air pollution emission from residential wood stove usage. The number of total wood stoves is estimated by the survey of wood stove manufacturer. And air pollution emission factors for the wood stove are investigated using the flue gas measurement by U.S. EPA particulate test method (Method 5G). As the results, the $PM_{10}$ and CO emission factors of wood stove are estimated as 7.7 g/kg-wood and 78.8 g/kg-wood respectively. The annual $PM_{10}$ and CO emissions from wood stove are calculated as 1,200~3,600 ton/year and 12,600~36,400 ton/year in Korea. It is confirmed that wood stove is the one of major sources of biomass burning, and the survey for activity data and the measurement for emission factors are needed for reducing the uncertainty of these emission data.

Ensuring the economic security of agro-industrial complexes of Ukrainian regions has become a top-priority task of state regional policy, as their stable functioning is an essential element of economic security of the whole country. It is overcoming threats to the development of the agro-industrial complex that ensures its further effective functioning and has a significant impact on the economic security of our state. Methods: logical method; methods of system analysis; synthesis; economic and statistical method; method of expert assessment; SWOT analysis; economic and mathematical modelling and planning. Results. Characteristic features of economic security have been given. The essence and significance of the agro-industrial complex in improving the economic security of the state have been determined. It has been noted that in recent years, the agro-industrial complex, which acts as a driver of the domestic economy and has a direct impact on the development of the country, has been growing (in 2019 the cereal and legume harvest exceeded 75 million tons, 20,269 thousand tons of potatoes were dug, more than 15 million tons of sunflower, 9,688 thousand tons of vegetables and 2,119 thousand tons of fruits and berries were harvested, meat and egg production increased by 137.5 thousand tons (or 5.8%) and 545.5 million pieces (or 3.4%), respectively, the number of employed population in agriculture increased by 139.8 thousand people (or 4.9%), the labour productivity in crop production increased by UAH 294.4 thousand (or 44.6%), in livestock production - by UAH 311.3 thousand (or 61.8%)). Based on the system of production and economic indicators, the analysis of the state of the agro-industrial complex has been carried out. Taking into account the results of the obtained data and using SWOT-analysis, the major threats to the development of the agro-industrial complex have been identified. Ways of overcoming threats enhancing the economic security of Ukraine have been proposed.
