The "Namul" is a Korean common vegetable food composed of edible young leaves and soft stalks of wild plants or cultivating vegetables and treated with traditional condiments. It has been widely used as not only a regular diet but seasonal foods or special ceremonial foods. In this thesis, the kinds of edible plants for namul were philologically approached by books published in Korea from Koryo to Chosun dynasty. The first historical record about cultivated vegetable as food in Korea was a garlic and a gourd in $\ulcorner$Samkuksaki$\lrcorner$. According to numerous records, edible wild plants might have played an important part as food resources, since they have variable edible portions as famine relief foods. Four kinds of namul were first introduced in Koryo age, but in Chosun dynasty over eighty kinds were recorded. The root of ballonflower and white radish were most commonly used for raw namul and bamboo shoot and squash for boils ones. Most kinds of namul were introduced in $\ulcorner$Zeungtosanrimkwungiae$\lrcorner$ and $\ulcorner$Limwonsiprwukji$\lrcorner$ influenced by pragmatism in later half period of Chosun. The chronic state of famine in later half period of Chosun caused to introduce various edible wild vegetables, and had greatly influenced on the Korean people to acquire vegetarian food habits and to favor salty taste. It seems to need a further study on recent nutritional problems including dietary fiber.ary fiber.

The objectives of this study were to compare the quality changes of cheese slices individually packed in four kinds of edible pouches in order to select the most suitable variety for individual packaging. The edible Z2 pouch (zein with oleic acid) was selected as maintaining the best cheese qualities based on the physical and microbiological changes undergone by the samples over 4-week storage at $5^{\circ}C$. The cheese sample individually packed in Z2 inner edible pouch and repacked in a plastic (OPP/LLDPE) outer pouch was not significantly different in physical and microbiological changes from that individually packed in a plastic (OPP/LLDPE) inner pouch and repacked in a plastic (OPP/LLDPE) outer pouch. Therefore, it may be concluded on the basis of the physical and microbiological evidence that the Z2 edible pouch can be used as an inner package for cheese slices when it is inside a plastic outer pouch.

Moisture sorption characteristics of edible composite films were determined and compared against moisture barrier properties. Edible composite films were Z1 (zein film with polyethylene glycol(PEG) and glycerol), Z2 (zein film with oleic acid), ZA1 (zein-coated high amylose corn starch film with PEG and glycerol), and ZA2 (zein-coated high amylose corn starch film with oleic acid). Z2 film showed the lowest equilibrium moisture content (EMC), monolayer value ($W_m$), water vapor permeability (WVP), and water solubility (WS). Surface structure of Z2 was relatively denser and finer than that of other edible films. GAB $W_m$ and C values decreased, while K values increased with increasing temperature. Correlation coefficients of WS:EMC and WVP:EMC at Aw 0.75 were higher than those of WS: $W_m$ and WVP: $W_m$, respectively. EMC values at Aw 0.75 appeared useful for evaluating or predicting moisture barrier properties of edible films.

Medicinal uses of edible and other plants for prevention and cure of obesity and overweight associated metabolic and mental health problems have since long been known to scholars and practitioners of Ayurvedic and other traditionally known system of medicine. Modernized versions of numerous edible plant derived formulations mentioned in ancient Ayurvedic texts are at present some of the most popular, or best selling, herbal remedies in India and numerous other countries suffering from double burden of diseases caused by malnutrition and obesity. Preclinical and clinical information now available on edible plants and their bioactive constituents justify traditionally known medicinal uses of products derived from them for prevention and cure of obesity associated type-2 diabetes, psychopathologies and other health problems. Such information now available on a few edible Ayurvedic plants and their formulations and suggesting that their stress response regulating effects are involved in their broad spectrums of bioactivity profiles are summarized in this communication. Implications of recent physiological and pharmacological observations made with numerous phytochemicals isolated from edible plants for better understanding of traditionally known medicinal uses of herbal remedies are also pointed out.

The mineral dissolution sensor system using GMR-SV and glass/Mg(200 nm) was prepared and characterized. The magnetic field sensitivity of GMR-SV to microscopic magnetic variation was about 0.8%/Oe. The change that occurs when Mg-film dissolves in water, the solubility of water, which is one of the basic properties of mineral water, was sensed by measuring the subtle variation of an electric current. In the case of edible water with Mg mineral added, bubbles were generated on the surface of the Mg film in the first 45 minutes, and the number of drops that were dissolved more rapidly than with the tap and DI waters later reduced to zero. For the edible water samples that each had different mineral Mg concentrations, the Mg solubility speed significantly differed. After injecting Mg film into the edible water, the magnetoresistance of the output GMR-SV signal decreased from a maximum of $45.4\;{\Omega}$ to a minimum of $43.6\;{\Omega}$. The measurement time was within 1 min, giving the rate of change ${\Delta}R/{\Delta}t=0.18\;{\Omega}/s$. This measurement system can be applied to develop a mineral Mg solubility GMR-SV sensor that can be used to sense the change from edible water to reduced alkali.

Objectives : The aim of the research is to study the edible parts and cooking methods for the Korean medicinal plants using documents of Japanese occupation era. Through this study, we expect that it will be used as a basis data on further Korean traditional edible herb. Methods : The research analyze the usage of 74 species of medicinal plants that are listed in the 『Wild Food Plants of Chosen(Korea)』 along with analyzing 8 extra documents about famine relief plants and cooking method written during Japanese occupation. Results : The result shows that the sprouts and buds are the most popular for the edible purposes but they are never used for medical reason. Roots and fruits take the highest percentage when it comes to medical purposes. Types of medicinal plants that were used a lot of cooking methods were side dishes such as 'Namul, Saengchae, Jangajji'. Conclusions : Using medicinal plants for edible and medical purposes were traditionally familiar with Korean culture but the changes provoked by industrialization forbid the knowledge to pass through. However, recently, the trend of having a healthy life interests people to backtrack this traditional way of using medicinal plants with new purposes. To inherit traditional knowledge and for the future development of Korean traditional ingredients, further research should be conducted.

The reasons for selecting insects as future food are high growth and feed conversion rates, reproduce quickly, low environmental footprint, valuable source of nutrients, and source of a various undeveloped functional materials. Since 2014, Tenebrio molitor larva, Protaetia brevitarsis larva, Allomyrina dichotoma larva, and Gryllus bimaculatus were registered as new food in Korea because it has been scientifically proven that they are not harmful to eat and nutritious. Therefore they can be legally produced and sold as food. Accordingly, there are 7 species of edible insects including grasshopper, silkworm pupa, and Baekgangjam in Korea. To improve aversion to edible insects, using their powder, chop, and gravy hidden their morphology, we developed more than 100 different kinds of recipes for general food menu, held several times tasting events to be familiar with edible insect food, and published cookbooks. Moreover, we developed more than 50 kinds of recipes for patients. To eat the insect food more and more people, we have been analyzed various function of insects. If health food based on the results of functional analysis is developed, edible insect's value will be raised. If various insect foods are developed and consumed by people, edible insect market will grow up more than 100 billion won in 2020.

In August 2021, we surveyed diseases of wild vegetables grown in Taebaek, Gangwon Province, Korea. During the disease survey, we observed severe damping-off symptoms in young edible aster (Aster scaber) plants in a vinyl greenhouse investigated. The incidence of the disease in the plants ranged from 5% to 20%. Diseased plants of edible aster were collected from the vinyl greenhouse, and fungi were isolated from petiole lesions of the diseased plants. Rhizoctonia sp. was consistently isolated from the petiole lesions. We examined morphological characteristics and anastomosis groups of nine Rhizoctonia sp. isolates obtained from the petiole lesions. The examination results revealed that all the isolates corresponded to Rhizoctonia solani AG-4 based on the morphological characteristics and anastomosis test. Three isolates of R. solani AG-4 were tested for their pathogenicity on edible aster plants by artificial inoculation. Inoculation tests showed that the tested isolates caused damping-off symptoms on the inoculated plants. The induced symptoms were similar to those observed in the vinyl greenhouse investigated. Damping-off of edible aster caused by R. solani AG-4 is first reported in this study.

To investigate the antimicrobial activity on bacteria causing a respiration disease and antioxidant effects of water extracts from 12 kinds of wild edible vegetables, we extracted the water extracts for 72 h in $7^{\circ}C$ using distilled water as solvent. The water extracts except Ixeris dentate and Allium monanthum had high concentrations of phenol compounds and flavonoids. Liguraia fischeri specially had the highest level on total phenol compounds and flavonoids with 205 ${\mu}g/mL$ and 98. 86 ${\mu}g/mL$, respectively. The each 0.05% extracts of Sedum sarmentosum and Liguraia fischeri had high effect on the DPPH radical scavenging activity among wild edible vegetables and the most extracts promoted antioxidant activity with increasing concentration of extract. The catalase activity of Erysimum aurantiacum and Aralia elata showed more than 150 units per g of fresh tissue. The effect of antimicrobial activity on water extracts showed characteristic activity. Only Staphylococcus aureus KCTC 1928 and Corynebacterium diptheriae KCTC 3075 were inhibited cell growth on the other hands, the remainder of bacteria was not inhibited cell growth. Nevertheless, the extracts of wild edible vegetables had specific concentration as MIC for antimicrobial activity respectively. In case of the extract of Aster scaber, Erysimum aurantiacum, and Allium monanthum had over 30% antimicrobial activity on the bacteria causing a respiration disease. In results, the wild edible vegetables include high concentrations of total phenol compounds and flavonoids that give a good antioxidant activity and antimicrobial activity. Therefore the wild edible vegetables are functional food for anti-aging and physiological activation.
