최근 국내에서는 식품에 대한 관심도가 높아짐에 따라 먹거리에 건강·환경·미래지향적 가치가 부여되고 있으며 식품 산업에서도 신규 식품 개발이 증가하는 추세이다. 식단을 구성할 때 기준이 되는 식품교환표는 개정과정에서 많은 인력과 시간이 소요되기 때문에 식품 섭취 변화를 신속하게 반영하기 어렵다. 본 논문에서는 식품교환표의 활용도를 높이기 위한 식품교환표 갱신 기법을 제안한다. 제안 기법은 의사결정트리 모델을 학습하여 새롭게 추가된 식품의 정보를 바탕으로 식품군을 분류하여 식품교환표를 갱신한다. 이는 영양 관리가 필요한 당뇨병 환자 등에게 실용적이며 기호성·다양성이 높은 식단을 구성하는 데 도움을 준다.

This was a clinical trial study to aid the recovery of elderly female alcoholic liver disease patients by providing a balanced nutritional supplement comprising soymilk. All patients gave their consent before enrolling. The average demographics of the subjects were age 81.57 years, height 150.43 cm, weight 52.67 kg, and body mass index 24.15 kg/m². An increase in the daily consumption of fruits and fruit juice was observed after the patients had started taking the balanced meal as compared to before. Intakes of vitamin A, vitamin C, vitamin E, and cholesterol decreased after consuming soymilk, whereas vitamin B₁₂, niacin, folic acid, and dietary fiber significantly increased (P<0.05). Blood cholesterol and BUN levels showed a decreasing tendency. Our results indicate that consuming soymilk in a balanced diet for female patients afflicted with alcoholic liver disease helps improve their nutritional status by increasing the nutrients lacking in the body.

In this study, silkworms fed Cudrania tricuspidata leaves were powdered, and hydrolytic enzymes, including viscozyme, papain, and flavourzyme, were added to verify the functionality of the different mixtures. In the general component analysis, the C. tricuspidata silkworm (CS) group exhibited higher crude protein and ash content than did the other groups, and the enzyme-treated groups exhibited higher carbohydrate content than the CS group. The DPPH and ABTS radical scavenging activities were significantly higher in the CS treated with viscozyme (CSV) and the CS treated with viscozyme/flavourzyme (CSVF) than in the other groups, with the CSV group showing the highest reducing power. ACE inhibitory activity was significantly higher in the CS treated with visocozyme/papain (CSVP) than in the CS group. In conclusion, rather than using powdered silkworms fed C. tricuspidata leaves, it would be more effective to use hydrolysates from C. tricuspidata silkworms as raw materials for functional foods.

This study was carried out to investigate the various roles and effects of Morinda citrifolia L.(noni) on the human body and to utilize the findings obtained for future disease related research on food and nutrition. Morinda citrifolia L. has been used in folk medicine by Polynesians for over 2,000 years and is reported to have a broad range of therapeutic effects. Noni is an alkaloid system such as proxeronine, scopoletin, octanoic acid, terpenoids, alkaloids, anthraquinones, nordamnacanthal, morindone, rubiadin, b-sitosterol, flavone glycosides, linoleic acid, acubin, L-asperuloside, caproic acid, caprylic acid, ursolic acid, rutin. Noni's side effects have been reported to affect anti-inflammatory, analgesics, LDL antioxidant, anti-tumor, antifungal, antibiotic, antiviral, antiparasitic and immunosuppressive effects. In particular, noni's efficacy is considered to be important for the prevention of diseases by inhibiting active oxygen, which is a direct cause of oxidative stress, through various metabolites through 'xeronine system'. Noni's functions and effects that have been examined in this study include anti-inflammation, pain relief, antioxidant, anticancer, hepatocyte protection among others. Therefore, noni's extracts are considered highly useful for diverse scientific and nutritional health functional foods.

안면 인식은 Face ID를 비롯하여 미아 찾기, 범죄자 추적 등의 분야에 도입되고 있다. 안면 인식은 최근 딥러닝을 통해 인식률이 향상되었으나, 측면에서의 인식률은 정면에 비해 특징 추출이 어려우므로 비교적 낮다. 이런 문제는 해당 인물의 정면이 없고 측면만 존재할 경우 안면 인식을 통한 신원확인이 어려워 단점으로 작용될 수 있다. 본 논문에서는 측면 이미지를 바탕으로 정면을 생성함으로써 안면 인식을 적용할 수 있는 상황을 확장하는 인공지능 기반의 안면 정면화 모델을 구현한다. 모델의 안면 특징 추출을 위해 VGG-Face를 사용하며 특징 추출에서 생길 수 있는 정보 손실을 막기 위해 U-Net 구조를 사용한다.

스카이라인 질의는 객체의 속성을 기준으로 사용자의 선호에 적합한 대상을 탐색하는 기법이다. 기존 스카이라인 질의는 일괄처리 방식으로 탐색 결과를 반환하지만 대화형 앱이나 모바일 환경과 같이 잦은 위치이동 발생 시 일괄처리 방식으로 스카이라인 질의 결과를 신속하게 받기 어렵다. 최근접 이웃(Nearest Neighbor) 알고리즘은 사용자와 상호 작용이 필요한 대화형 앱에서 실시간으로 선호 객체를 탐색하여 사용자에게 전달함으로써 객체의 반환 속도를 향상시켰다. 그러나 최근접 이웃 알고리즘은 객체 탐색 과정에서 반복적인 비교 연산을 수행하여 불필요한 탐색 시간이 소요된다. 본 논문은 대화형 앱에서 신속한 스카이라인 결과를 산출하고자 연산 대상 객체의 범위를 축소함으로써 최근접 이웃 스카이라인 질의 알고리즘의 성능을 향상시킨 전처리 기법을 제안한다. 데이터 객체는 최대 40,000 개의 실험에서 제안 기법은 최근접 이웃 알고리즘보다 50% 빠른 성능을 나타내어 본 연구의 가용성이 증명되었다.

In this study, the nutritional properties of sterilized and non-heat-pressed raw perilla oil (SRPO) were studied and its potential as a functional food was evaluated. The copper, cobalt, and calcium levels were high in sterilized and SRPO. The total polyphenol content and ABTS radical scavenging activity were the highest in SRPO, whereas nitrite scavenging activity was the highest in 45℃ cold pressed perilla oil (CPPO). The above results confirmed that sterilized and non-heat-pressed perilla oil had high mineral and total polyphenol contents, as well as ABTS radical scavenging activity and nitrite scavenging ability. The peroxide value of SRPO decreased as the storage period increased, and the acid value of low-temperature pressed perilla oil over 65℃ (LPPO) significantly increased. This work also provided an opportunity to develop a new method for manufacturing perilla oil, and it is hoped that these experiments will form a basis for the commercialization of perilla oil.
