The physicochemical and antioxidant properties of cookies prepared using powders of barley sprout (BS), lemon balm (LB), and green tea (GT) were studied. The same dough density was maintained in all the sample groups. The experimental group to which the natural ingredients containing antioxidants were added did not show any significant change in the appearance of cookies compared to the control. LB and GT cookies showed significantly lower hardness compared to the control (p<0.05). Control showed the lowest antioxidant effect when assessed with 2,2-diphenyl-1-picrylhydrazyl. (DPPH) and this gradually increased in the order of BS, LB, and GT. The antioxidant activity of GT was 7 times higher as compared to the control (p<0.05). The antioxidant activity assessed using 2,2'-azino-bis (3-ethylbenzothiazoline-6-sulfonic acid) (ABTS) also showed results similar to that seen with DPPH. GT showed a significantly higher total phenol content, about 2-3 times higher compared to the control (p<0.05). GT had significantly higher total flavonoid content than that of the control (p<0.05). Thus, the addition of natural antioxidant ingredients such as sprout barley, lemon balm and specifically green tea, in the preparation of cookies, resulted in excellent antioxidant activity with similar physicochemical quality characteristics. The study suggests that it is possible to develop cookies that are competitive in terms of nutritional and physiologically active functions.

In this work, the calcium alginate microcapsules containing lemon oil were prepared by emulsification-internal gelation and their potential use as aromatherapy was examined by the controlled release system. The lemon oil encapsulated in the alginate was successfully observed by Fourier transform (FT-IR) spectroscopy and differential scanning calorimeter (DSC) measurements. Analysis of the diameters and shapes of microcapsules was conducted by scanning electron microscopy (SEM). The mean diameters ranging from 4 to 7 um and encapsulation yield ranging from 50 to $85\%$ were obtained. The controlled release of the lemon oil at $37^{circ}$ was demonstrated by the infrared moisture determination (IMDB). It was found that the amount of released lemon oil decreased with increasing concentrations of alginate and $CaCl_2$ due to the higher the cross-linking density of the capsules prepared. The oil release from the capsule was measured as a function of physical force. We confirmed that the external factor could control the collapse of capsule wall and the release rate.

Different types of coagulant and characteristics of its concentration added in the process of making milk curd were compared in this study. The pH of whey decreased when the amount of coagulant increased. The turbidity of whey was decreased when 5% of acetic acid and lemon juice were put into as coagulants. The texture of milk curd made with cow's milk and skim milk was measured the highest when acetic acid and lemon juice were added at 3, 5% of their concentration. The fracturability of milk curd made only with cow's milk decreased as the concentration of each coagulant increased. The cohesiveness was decreased as concentration of coagulant increased. The springiness was slightly changed depending on its coagulant but didn't show much of difference. The gummminess of milk curd made with cow's milk was increased when 3, 5% of coagulant was added. The result of sensory evaluation of milk curd showed that preference of milk curd wasn't depending on types of milk nor its coagulant. Also, flavor preference showed better when lemon juice was added. Preference in texture of milk curd was the highest made with cow's milk and skim milk. Preference in taste was high when 10% of lemon juice was added to skim milk and preference in its appearance showed higher when the alum was added as a coagulant to both cow's milk and skim milk than other coagulants.

Recently, consumers have gained an interest in natural and minimally processed foods, inciting the food industry to consider using of natural products as preservatives. Strawberries are a widely consumed fruit but are also highly perishable. Therefore, in this study, the physicochemical properties of strawberries (Fragaria×ananassa) were evaluated after a 12-h treatment with lemon essential oil (Citrus×limon) or cinnamon essential oil (Cinnamomum cassia) vapor during storage at 22℃ for 4 days in an accelerated shelf-life study and 4℃ for 18 days in a validation study. Weight loss was blunted in fruit treated with oil vapor during the first days of storage (p<0.05). Lemon essential oil delayed fruit darkening (p<0.05) but reduced the firmness of strawberries (p<0.05). Strawberries treated with cinnamon essential oil had a higher concentration of reducing sugars (p<0.05), and a decrease of 16.7% visible decay, although the difference was insignificant. Oil vapor treatment did not alter the pH, organic acid content, or soluble solid content during storage compared to the control. Since lemon and cinnamon essential oils have well-documented antimicrobial properties, they may be suitable for the natural preservation of fruit. This study provides new information on using essential oil vapor treatment to preserve fruits, and potentially decrease fruit loss and waste.

To investigate the characteristics of plant growth and flower quality of gerbera 'Sunny Lemon' by amount of nutrient solution, young seedling plants, 'Sunny Lemon' were transplanted to rock-wool and medium of peat moss and perlite mixed with 1 to 2 and they were acclimatized in greenhouse during about 1 month. Nutrient solution supplied to the plants is sonneveld solution of 1/2 concentration and treatments launched June 24, 2010 when average plant height was $20{\pm}1cm$. Nutrient contents as a standard for starting point of irrigation by time domain reflectometry (TDR) were determined with 60-65%, 70-75%, and 80-85%. Results of growth during vegetative growth, plant height, leaf width and leaf number increased by 10% in rockwool, but they were not significantly different. As for plant growth depending on nutrient content, 80-85% treatment showed the highest values. Leaf number increased by 60%, and leaf width and plant height had a about 40% increase than initial growth. Effectiveness for flower quality, yield and days to flowering were superior when nutrient content of media was higher than in the others. Especially, average days to flowering in 80-85% content was advanced by 7-10 days compared to the day in 60-65% treatment. The total amount of nutrient supply per plant was higher in mixed medium than in rockwool, but change patterns of EC and pH were enhanced in rockwool. Based on our results, we recommended that growth, cut flower, and yield of gerbera 'Sunny Lemon' were more effective when nutrient content of mixed medium was maintained at 80-85%.

Pectin was enzymatically extracted from industrial lemon pomace by using an endo-polygalacturonase from Aspergillus niger as a processing aid and compared to pectin extraction by hot hydrochloric acid. The yield of pectin was 17.6 and 20.2% with enzymatic and acidic treatments, respectively. The molecular weight distribution did not vary greatly between the samples extracted with enzyme or acid. Large differences in charge density were observed, however, when the samples were analyzed by anionic-exchange chromatography. Pectin extracted by the enzymatic treatment indicated higher charge density than that obtained by hydrochloric acid. The higher charge density could due to the presence of endogenous lemon pectinesterase, which was activated at low pH 4.5 in situ conditions during the process of enzymatic extraction, leading to low methoxylated pectin with a higher charge density.

The distributions of (or constraints for) amplitude and phase around C-points, including Lemon, Mon-Star and Star, are studied. A Cartesian coordinate system with origin at the C-point is established. Four curves, where the azimuthal angles of polarization ellipses are 0°, 45°, 90°, and 135° respectively, are used to determine the distributions. Discussions of these constraints illustrate why Mon-Star is rarer than Lemon or Star in experiments. The transformation relationships between these three polarization singularities (PSs) are also discussed. We construct suitable functions for amplitude and phase according to their constraints, and simulate several PSs of particular shapes. With the development of modulation techniques for amplitude and phase, it is clear that this work is helpful for generating arbitrarily shaped C-points in experiments.

When a dispute or conflict occurs, standard methods for resolving them include resolution by trial or resolutions outside of courts. An alternative dispute resolution method called ADR that aims at remedying disputes instead of filing lawsuits is used commonly throughout the world, including the US and China. ADR, which is a remedy method outside of courts, includes negotiation, arbitration, or mediation between the concerned parties, and the arbitration system has several advantages. The Lemon Law is a consumer protection law of the United States that was enacted in 1975. This law prescribes that when specified quality standards are not met repeatedly due to defects in vehicles or electronic products, the manufacturer must provide exchanges or refunds to consumers. Korea also enacted a newly revised automobile management act, the Korea "Lemon Law," on January 1, 2019, which allows consumers to receive exchanges or refunds from the manufacturer if the same malfunction repeatedly occurs after purchasing a new automobile. There have recently been many cases of large fires occurring while driving import vehicles, causing huge public rage; therefore, interest is being focused on the revised automobile management act. Part 5-2 of the automobile management act was newly added to implement automobile exchange or refund arbitration systems. It is desirable to utilize the arbitration system to smoothly resolve automobile-related disputes that have recently increased significantly, and it is thus being used frequently for practical purposes.

This study examined the growth of herb plants in response to irrigation on a green rooftop area in order to select herb plants that can be used for rooftop greening. Apple Mint (Mentha suaveolens), Lemon balm (Melissa officinalis), Spearmint (Mentha spicata), Pineapple sage (Salvia elegans), Choco Mint (Mentha ${\times}$ piperita 'Choco Mint'), Ox-eye Daisy (Chrysanthemum leucanthemum), Roman Chamomile (Anthemis nobilis) and Thyme (Thymus vulgaris) showed increased growth when irrigated. Conversely, Lavender (Lavendula angustifolia ), Peppermint (Mentha ${\times}$ piperita ), Vicks Plant (Plectranthus tomentosa), Feverfew (Tanacetum parthenium), Rosemary (Rosmarinus officinalis), Tansy (Tanacetum vulgare), Lemon Verbena (Aloysia triphylla), Heliotrope (Heliotropium arborescens), Soapwort (Saponaria officinalis) and Lady's mantle (Alchemilla vulgaris) demonstrated satisfactory growth regardless of irrigation. Peppermint, Tansy, Lemon Verbena, Soapwort, and Lady's mantle seem to be suitable for green rooftop because of their overwintering ability and drought hardiness. Pineapple sage, Apple Mint and Thyme would seem to be inappropriate for rooftop greening because they showed negative growth response to drought and failed overwintering. Although Spearmint, Lemon balm, Choco Mint, Ox-eye Daisy and Roman Chamomile had reduced growth during dry conditions, they were able to overwinter satisfactorily and can be used as rooftop plants with irrigation.
