  • The objects of this study are to find out (1) real situation of the food supply in prison under Imperial Government of Japan more cleary (historical meaning) and (2) which might help in understanding wrong present food consumption patterns in Korea which causes environmental as well as health problems. It is generally known that the length of the Japanese occupation for Korea is 36 years. However, it is concluded in this study that it was longer (70 years ; from 1875 to 1945 from when Japanese Army attacked and occupied Yungjongdo and Kanghwado island to e time when they were defeated on World War II.) Korea was annexed by Japan in 1910 then the Imperial Government of Japan dismissed the Korea Army, controlled the Office of Justice and the management of prison by force. Since then about 50% of all land was fell into Japanese Government ownership and 80% of Korean farmers became as tenant. After this change, Korea farmers were forced to pay extremely high rent (up to 80% of its harvest). Forced immigration, low price procurement of grain by Japanese government up to more than 30%of their production, was practiced. Accordingly, the food situation of Korean farmers became miserable, which may caused more violations of Imperial Japanese Law. Malnutrition, epidemic diseases, mortality rate of infants soared and average life expectancy shortened to 20-30 years old. This was the period of World Economic Crises and Food Crises in Japan. It was said then that if one Japanese comes to Korea then 200 Koreans will starved to death. Meanwhile, Proconsul Bureau of Chosun requested to the Department of Medicine, the Imperial University of Kyungsung to survey food supply situation of Koreans in prison throughout Korea. Objectives of the survey then was not only to find out scientifically whether it is agreeable in maintaining prisoner's health and also find out the possibility to save food during food crisis. Survey was started from 1923 and ended in 1945, and it focussed on prisoners in the Seodaemoon Prison. This report is the outcome of the first survey. They concluded that the food supplied was nutritionally (had) no problem, in compare with those of workers in the factory, students in the dormitory in Japan and with those of prisoners in Taiwan, France and Germany. Amount of grain supplied were different according to their work lord and was divided into 9 different levels. Total grain was consisted of 50% millet, 30% soybean and 20% indica rice(variety). However, there were no difference in the amount of supply of side dishes between work groups. For the highest working group, 3280g of boiled grain per day was supplied to make stomach full but as a side dishes, salty fermented bean paste, fermented fish and salty soups, etc. was supplied. Deficiency of animal protein were observed, however, high intake of soybean may possibly caused animal protein deficiency problem. On the contrary, the intake of water soluble vitamins were insufficient but the level of calcium and iron intake seems to be sufficient, however, imbalance of intake of nutrition may caused low absorbtion rate which might caused malnutrition. High intake of dietary fiber and low intake of cholesterol may possibly prohibited them from so called modem disease but may caused the defect in disease resistancy againist epidemics and other traditional disease. Over intake of salt(20-30g per day) was observed. Surveyors who attended in this survey, mentioned that the amount of food intake may nutritionally be sufficient enough but the quality of food(and possibly, the taste of food) were like that of animal feed. For the officials who received this report might consider that considering the war situation and food crisis, the supply situation of food in the prison may considered to be good enough(because they are not starving). But as a Korean who studied this report, one feel extremely pity about those situation because (situation of) those period were very harsh under the Imperial Law and keeping the Law by Koreans were almost impossible, therefore, about one third adult violated the Law and were put into jail. And they were treated like animals.

  • Rice paper is an element of Vietnamese cuisine that can be used to wrap vegetables and meat. Rice and starch are the main ingredients of rice paper and their mixing ratio is important for quality control. In a commercial factory, assessment of food safety and quantitative supply is a challenging issue. A rapid and non-destructive monitoring system is therefore necessary in commercial production systems to ensure the food safety of rice and starch flour for the rice paper wrap. In this study, fluorescence hyperspectral imaging technology was applied to classify grain flours. Using the 3D hyper cube of fluorescence hyperspectral imaging (fHSI, 420 - 730 nm), spectral and spatial data and chemometric methods were applied to detect and classify flours. Eight flours (rice: 4, starch: 4) were prepared and hyperspectral images were acquired in a 5 (L) × 5 (W) × 1.5 (H) cm container. Linear discriminant analysis (LDA), partial least square discriminant analysis (PLSDA), support vector machine (SVM), classification and regression tree (CART), and random forest (RF) with a few preprocessing methods (multivariate scatter correction [MSC], 1st and 2nd derivative and moving average) were applied to classify grain flours and the accuracy was compared using a confusion matrix (accuracy and kappa coefficient). LDA with moving average showed the highest accuracy at A = 0.9362 (K = 0.9270). 1D convolutional neural network (CNN) demonstrated a classification result of A = 0.94 and showed improved classification results between mimyeon flour (MF)1 and MF2 of 0.72 and 0.87, respectively. In this study, the potential of non-destructive detection and classification of grain flours using fHSI technology and machine learning methods was demonstrated.

  • A survey on the nutritional state was conducted from June 11 to Nov. 30, 1971, on 673 women workers $(16{\sim}25\;yrs)$ Jorking in a factory of food industry. Total body fat content was measured by skin-fold thickness (S. F. T.) with caliper at three region of the body. And it was calculated by regression equation, with the following conclusions were abtained. 1. The mean with standard deviation body height and weight of the Korean women workers were $155.0{\pm}4.21\;cm$ and $50.1{\pm}5.31\;kg$; respectively. 2. Their mean skin-fold thickness with their standard deviation triceps region of upper arm, 14.3{\pm}3.42$; Subscapular region, $18.0{\pm}5.57mm$; Abdominal region, $19.3{\pm}4.87mm$ and total aveager, 17.2{\pm}3.91mm$. 3. The body fat contents according to body fat weight regression equation were;fat weight. 10.7 kg; fat-free weight, 39.4kg; fat weight/ fat-free weight, 27.5%; fat-free mass/ total body mass 77.6%, and fat weight/ total body mass,21.6%. 4. Since the sknin-fold thickness between the triceps and upper abdominal region and between the former and Subscapular region were correlated with the coefficients of 0.838 and 0.615 respectively. and the following regression equations were established. a) S. F. T. of Subscapular region $(mm)=0.929{\times}$S. F. T. of triceps region (mm)+4.707. b) S. F. T. of Abdominal $region(mm)=1.24{\times}$S. F. T. of triceps region(mm)+1.50. Nutritional survey on the women workers in a fact ory of food industry, performed as above by the S. F. T. method, elucidated the fact that their nutritional state is as good as the control healthy female, and that their energy uptake may well be said to be satisfactory.

  • The city is developing into a smart city. Smart villages and smart farms are developing in rural areas. Architectural technology needs synergy with smart cities, smart villages, and smart factories (intelligent factories) to help architectural experts understand smart farms and build facilities and equipment. Smart farms require design and construction technology with architectural structure and function. The purpose of this study was to investigate the current status and cases of smart farms in Korea and to investigate cases abroad. The conclusion is as follows. ① Smart farms are developing rapidly. The Korean government is expanding smart farms by utilizing ICT technology and infrastructure. ② 'Smart Farm Innovation Valley', which has been promoted since 2018, is a cutting-edge convergence cluster industrial complex that integrates production, education, and research functions such as start-ups and technological innovation. ③ In domestic cases, smart farms are operated in subway stations, buildings, supermarkets, and restaurants. ④ In the Japanese case, a dome-type smart farm was being operated. It utilized factory wastewater, waste heat, renewable energy, and used new materials. Otemachi Ranch raised livestock and provided a lounge on the 13th floor of the building. ⑤ In the cases of Korea and Japan, the smart farm technology is very similar. As stated earlier, since the food culture and agricultural technology of both countries are similar, we hope to promote the development of smart farms that can reduce concerns about future food by communicating and sharing mutual technologies.

  • 최근 곤충산업은 애완곤충, 천적 등 산업에서 사료, 식용, 약용곤충으로 그 활용범위가 확대되면서 곤충 원료의 품질관리에 대한 요구가 커지고 곤충 제품의 안전성 확보에 관심이 높아지고 있다. 전세계 곤충산업 시장은 많은 소규모 농가형 기업과 소수의 대기업으로 구성되어 있으며 전통적인 수작업 사육에서 고도로 자동화되고 기술적으로 진보된 플랜트형 사육 등 다양한 기술 수준의 사육형태가 존재한다. 산업규모가 확대되는 과정에서 사육환경의 설계는 온습도, 공기질 조절과 병원체 및 기타 오염 물질의 전파를 방지하는 것은 중요한 성공 요인이 되며 사육에서 부화, 사육, 가공에 이르기까지 생산의 안전성을 유지하기 위해서 통일된 운영시스템 아래 통제된 환경이 필요하다. 따라서 곤충의 생육과 사육환경의 빅데이터화 된 데이터베이스를 기반으로 외부 환경 변화에도 안정적인 사육환경 유지가 가능하고 곤충성장에 맞추어 사육환경을 제어하며 노동력 감소와 생산성 향상을 이루기 위한 ICT 기반 곤충 스마트팩토리팜의 설계 및 운용알고리즘을 개발하는 것은 곤충산업 발전의 필수 선결조건이 되고 있다. 특히 유럽 상업용 곤충사육시설은 상당한 투자자의 관심을 받아 곤충 회사가 대규모 생산시설로 건설하고 있는데 이는 EU가 2017년 7월 물고기양식 사료원료로 곤충 단백질의 사용을 승인한 후 가능해졌으며 이를 기반으로 곤충산업의 식용, 의료 등 다른 분야도 첨단기술을 접목하는 현상이 가속화되었다. 외국 곤충산업은 주로 전세계 식품 생산량의 30%에 이르는 소비 전 폐기물이라고 불리는 식품회사의 생산과잉 원료 등을 업사이클링을 통해 재활용생태계를 형성하는데 반해 우리나라는 가정 및 가게에서 발생하는 음식물폐기물 또는 농산물 가공부산물을 주로 이용한다는 점에서 사료 수집과 영양성분 유지, 위생 등 지속가능한 산업생태계를 이루는 데 어려움을 겪고 있다. 또한, 각 곤충 종은 고유하고 특정 사육기술을 요구하고 있다는 점을 감안할 때 곤충사육자는 각기 다른 종별 접근 방식을 채택해야 하는데 대부분의 곤충기업은 여전히 소규모로 운영되며 특히 농가형 기업의 경우 지식과 경험이 도제식으로 전승되는 경우가 많아 표준화되고 규격화된 사육기술이 유지되기 어려운 반면, 일부 곤충 기업은 대규모 사육시설에 스마트 통합 제어시스템을 도입하여 먹이주기, 물주기, 취급, 수확, 청소 시스템, 가공, 품질관리, 포장 및 보관과 같은 곤충 생산과 관련된 요소가 최적화된 사육 환경과 사육프로세스로 표준화되어가는 모습을 보이고 있으며 심지어 일부 유럽기업은 AI기술로 구동되는 완전 자율 모듈식 곤충시스템으로 사육 유지관리를 하고 있는 사례도 등장하기 시작하였다. 향후 전세계 곤충산업은 공급업체로부터 알이나 작은 유충을 구입하고 곤충을 성숙시키기까지 애벌레의 비육 즉 생산원료에 중점을 두는 시스템과 알을 낳고 수확하고 유충의 초기 전처리에 이르기까지 전체 생산 과정을 다루는 시스템, 곤충 유충 생산의 모든 단계와 제분, 지방 제거 및 단백질 또는 지방 분획 등 추가 가공 단계를 다루는 대규모 생산시스템 등으로 점점 세분화할 것으로 본다. 우리나라에서도 인공지능 및 ICT 첨단기술을 활용한 곤충스마트팩토리팜 연구 및 개발 등이 가속화되고 있어 곤충이 기존 사료, 식품 뿐만 아니라 천연 플라스틱 또는 천연성형소재 등 2차산업의 탄소제로 소재로 활용할 수 있도록 특정 종 육종과정 단축이나 기능성 강화를 위한 사육제어가 가능하도록 곧 곤충 스마트팩토리팜 한국형 맞춤사육시스템이 등장할 수 있을 것으로 보이며, 특히 곤충 제품의 지속 가능성을 높이기 위해 사료 및 자원 사용에 대한 통합 소프트웨어 접근 방식을 개발하는 것에 중점을 두고 진행되고 있다.

  • This study was made to analyze the condition and the needs of nutrition education considering the different stage of nutrition education recognized by the dietitian in industrial area. 165 female dietitian were surveyed by questionnaire and they were divided into 4 groups according to the different recognition stages of nutrition education: Pre-contemplation(PC) 4.8%, Contemplation(CO) 46.7%, Preparation(PR) 22.4%, Action & Maintenance phase(AM) 26.1%. For statistical analysis, SAS(Ver.8.1. for Window) was used to find out the distribution related with nutrition education and to calculate the scores of mean and standard deviation. General characteristics of the subjects are about 20 years old(71.5%), single(69.7%), careers over 5 years(40%) and university graduates(73.9%). The number of meals(p<0.05) and the employment status(p<0.05) were significantly different according to the recognized stage of nutrition education. The practice of nutrition education was different depending on the dietitian in the industry. Many of the factory dietitian were in pre-contemplation stage(87.5%), however, those in the office and service area were more in Action & Maintenance stage(27.9%). In the industrial area, just 26.1% of dietitian operated the nutrition education and most did not due to the work overload and insufficient support of staff(73.3%). The frequency for the most effective nutrition education was once a month(61.2%). The contents for desirable nutrition education were in the order of 'eating habits'(36.1%), 'relation with the daily life'(23.5%), 'food hygiene' (21.7%), 'nutrition knowledge'(9.7%), and 'disease prevention'(9%). In operating nutrition education, dietitian had concerns about 'insufficient support of staff', 'shortage of teaching materials' and 'lack of time'. And, the dietitian who were with lower recognition stage of nutrition education(P<0.05) concerned more about the insufficient educational contents. In conclusion, dietitian in the industry highly recognized the need of nutrition education, but it was so difficult to practice. For more programs and various materials should be developed, and the staff's perception, the view of dietitian and the meal service should be changed, too. For the health improvement of industrial workers, it would be necessary to proclaim the importance of nutrition education nationwide.
