It has already been a few years since the word Fintech in Korea started to attract attention. These days, they believed that Fintech was just a boom, but these days it is recognized as a catalyst for financial transformation. Large venture companies are also launching demonstration experiments by creating new organizations that can respond to Fintech. It feels like a big tide is coming to the cautious and conservative financial industry. Finance is made up of digital information. Fintech is an evolutionary process in which finance, expressed by digital information, is transformed into information technology (IT) and human economic activities are reorganized. It is FinTech. You won't be able to understand the real effects of Fintech by sticking to individual applications like remittance payments or household account book services. Fintech is an innovation that changes the structure of economic activity itself. In fact, it is from now on that a big impact will come. In other words, now is the time when we are thinking of a dream that we have not yet dreamed of. In this paper, I will examine how fintech originated, spread to Korea, and how it intends to change Korea's finance in the future. Financial institutions have used the fruits of information technology advances in the direction of pursuing stability and stability, without major changes in the way they work. However, the movement of Fintech that started in Silicon Valley in the United States shows that the fruit can be used in other directions. The fruit of technological progress is expected to expand year by year in the future. It is a request of the times to use it to improve user convenience and to pursue innovation that is beneficial to society. We expect the flow of Fintech to accelerate innovation in the Korean financial industry.

This study investigated whether or not the major bioactive compounds of Noni (Morinda citrifolia) are involved in anti-inflammatory activity through the JAK/STAT upper signaling pathway in RAW 264.7 cells. The experimental results show that the M. citrifolia ethyl acetate fraction (Mc-EtOAc) obtained by sequential fractionation with organic solvents from the plant's dried fruits exhibits the highest antioxidant activity. In addition, the cytoprotective effects of Mc-EtOAc against H₂O₂-induced oxidative stress in the RAW 264.7 cells suppressed cytotoxicity in a dose-dependent manner. The group pretreated with Mc-EtOAc at a concentration of 240 ㎍/ml showed higher cell viability of 84.5%, compared to 71.6% in the LPS-treated group, and LPS-induced NO production decreased to half the amount in the positive control group. Mc-EtOAc treatment also led to a significant dose-dependent reduction in iNOS expression. Although COX-2 expression was increased by 300% following LPS induction, it was significantly decreased in a dose-dependent manner by pretreatment with Mc-EtOAc at concentrations of 120 and 240 ㎍/ml. An inhibition of the mRNA expression of pro-inflammatory cytokines IL-1β and TNF-α was observed. The investigation also revealed that the phosphorylation levels of pJAK1 and pSTAT3 in LPS-induced RAW 264.7 cells were significantly reduced by Mc-EtOAc treatment.

In the present study, we assessed the effecs of fruit and vegetable bark resources rich in beneficial substances on the learning ability and memory improvement. It functions to inhibit the activity of acetylcholinesterase in brain tissue and improve cognitive functions in a simulation model of cognitive impairment induced by scopolamine. Hence, it can promote memory and learning ability. The formulation of the fruit and vegetable bark uses the extract of fruit and vegetable peels, which has long been used without causing toxicity in a wide range of food applications. Therefore, it can be used safely without a risk of side effects, even in the case of a long-term administration for the preventive purpose. Furthermore, the present study is a very beneficial study in the environment-friendly aspect in association with recycling of resources as it is based on the novel efficacies of fruit and vegetable barks which have been conventionally disposed as a refuse of fruits due to their poor sensory qualities despite the content of beneficial substances.

The purpose of this study was to compare the mineral and vitamin intake according to the stage of change in fruit and vegetable intake. The subjects consisted of 256 students, 122 males and 134 females, who are fourth, fifth and sixth grade in an elementary school located in Yeongi-Gun, Chungnam province. The dietary intake wasexamined by 24 hr dietary recall for 1 day and by food record for 2 days from April 19 to May 01, 2007. Stage of change of intake of fruits and vegetables of the students was categorized into three groups: precontemplation, contemplation and preparation, and action. The subjects at the stage of action took kimchi and vegetables more frequently, and also took more vitamin C as well. But the subjects at other two stages did not show any difference in the intake of any food group and nutrients. Percentage of the male subjects who took less than EAR did not show any significant difference by stage of change in all the nutrients. However, there was gradual decrease in the percentage of female taking less than EAR of vitamin C and vitamin B2. The result concludes that vitamin C intake significantly increase gradually as the stages of behavioral change of fruit and vegetable intake proceed although almost all vitamins and minerals tended to increase.

Botanical antimicrobial agent-grapefruit seed extract mixture (BAAG) have an unknown compounds which exhibit the antibiotic activities aganist microorganisms including bacteria and fungi. We have examined the effects of BAAG on the physiological function of Botrytis cinerea which was isolated from necrotic lesions of decayed fruits and vegetables such as cucumbers, grapes, tomatoes, and red peppers during storage. In the results of enzymatic activities related to the energetic metabolism there was no inhibitory effect of BAAG on the activities of several enzymes in vitro including glucose 6-phosphate dehydrogenase and malate dehydrogenase, while there was inhibitory effect of BAAG on the activities of hexokinase and succinate dehydrogenase. O-nitrophenyl-$\beta$-D-galactopyranoside(ONPG), the artificial substrate of $\beta$-galactosidase was hydrolyzed in the presence of BAAG, indicating that the membrane was pertubated by the BAAG. From the results we suggested that the antibiotic activity of BAAG is due to the change of membrane permeability of the cell. BAAG was fractionated and purified by silica gel and sephadex column chromatography. Among active fractions two peaks were identified as naringin and limonin when they were analyzed by by NMR and Fast atomic bombardment.

According to economical status, under-nutrition and over-nutrition coexist in preschool children in Korea. Subjects consumed more than RDA in most nutrients, and children in of the upper income class tended to have more nutrients than those of the low income class. Especially in case of energy, protein, fat, vitamin $B_2$, and P there were significant differences among the different classes. The mean calorie compositions of carbohydrates, protein and fat were $57{\sim}59:\;16{\sim}17:\;26{\sim}27$ and fat calorie percentage was higher than quantity recommended for Korean adults. Energy, protein, Fe, vitamin A, $B_1$ and C intakes were taken mostly from plant food sources. In the upper income class group, intakes of protein and vitamin $B_2$ from animal food sources were higher than in any other income classes. Intakes of iron, vitamin A, $B_1$ and C were largely provided by plant food group. Especially 44-45% of vitamin A were taken from vegetable and fruits group, which indicated that about 50% of vitamin A intake was the form of ${\beta}-carotene$. Also compared with other groups, in the upper income class group, the intakes of energy, protein, Ca, p, vitamin $B_1$ and vitamin $B_2$ from cereal and potatoes were significantly lower, and those of Ca and P from milks and meats, fishes & eggs were significantly higher(p<0.05). The mean fat intake in all subjects was $38{\sim}43g/day$. Regardless of income class, oleic acid($6.6{\sim}8.4g$) and linoleic acid($6.7{\sim}8.1g$) were the most abundant fatty acids contained in the diet. The upper class group consumed significantly more total saturated fatty acids and total monounsaturated fatty acids(p<0.05). In polyunsaturated fatty acids, there were no differences between 3 different income classes, but intakes of total ${\omega}6$ fatty acids in the upper class tended to be higher and those of total o3 fatty acids in low class tended to be higher. Therefore, ${\omega}6/{\omega}3$ tended to be higher in the upper class group. Regardless of income classes, P/M/S and ${\omega}6/{\omega}3$ ratios in all subjects were $0.9{\sim}l.3/1.0{\sim}1.1/1.0$ and $5.2{\sim}7.4/1.0$, respectively and were in a desirable range. Cholesterol intake of subject was 184-218 mg/day, which was comparable to the value of Korean adult intake.

Tn establish the criteria for appropriate seedling production method in the summer, the effect of container size and seedling age on the growth and yield were evaluated with tomato. The seedling quality was higher when seedlings were grown polyethylene in 9cm pots than in 72 cell plugs. Seedling quality increased with increase in seedling age in polyethylene pots, whereas seedling age did not affect seedling quality in plug trays. Fruits matured earlier on plants started from pot-grown transplants for a long duration than with plug tray-grown transplants for a shorter duration. Not only total yield in 4 months, but the early yield in the first 2 months, was higher with pot-nursed transplants than with plug tray-nursed transplants. With pot-grown transplants, The early yield in initial 2 months was the lowest in 25 day-old transplants, whereas there was no significant differences between 35- and 45-day-old transplants. Seedling age did not affect the cumulative yield for 3 months after the first harvest. With plug tray-grown transplants, the cumulative yield tar initial 3 months was the highest in plants grown for 35 days in the nursery, followed by 25 day and 45 day. However, there were no significant differences among seedling ages in the total yield.

Dietary fiber(DF) intake of teenagers was estimated and the major food sources of fiber were analyzed using three-day food records and data from 365 middle school students in urban, rural and fishing areas. Mean dwily DF intake of males was 9.2$\pm$3.9g in urban, 10.4$\pm$5.4g in rural, and 7.9$\pm$4.0g in fishing areas and the intake of female was 10.6$\pm$5.1g in urban, 10.6$\pm$5.2g in rural, and 7.7$\pm$3.3g in fishing areas. When related to energy intake, female consumed more DF(5.7$\pm$2.5g/1000㎉, 7.0$\pm$3.5g/1000㎉, 4.6$\pm$2.2g/1000㎉, in urban, and rural, fishing areas respectively) than males(4.2$\pm$1.3g/1000㎉, 4.6$\pm$1.5g/1000㎉, 4.4$\pm$2.0g/1000㎉ in urban, rural, fishing respectively). Mean crude fiber(CF) intake of males was 4.1$\pm$1.7g, 4.5$\pm$2.4g, 3.7$\pm$2.4g, and female's intake was 4.7$\pm$1.9g, 4.8$\pm$2.2g, 3.7$\pm$1.9g in urban, rural, and fishing areas respectively. The mean DF : CF ratio for the subjects was 2.2-2.6, indicating that the DF intake is 2-3 times that of CF intakes. The intakes of the two measures of fiber were highly correlated(r=0.7781) . The major food sources for DF were cereals, vegetables and fruits and the percentage contributions of the food groups to the DF intake were 27-37$\%$, 22-30$\%$, and 11.5-19.7$\%$ respectively. The present study indicates that the DF intake of teenagers is considerably lower than the recommended level and they need to consume more DF than that indicated by the present levels. The importance of nutrition education on health and dietary pattern should also be emphasized among teenagers.

For the elucidation of some information on processing properties of tomato, physicochemical characteristics of fruits were analysed for two group of cultivation pattern, non-proped cultivation (5 varieties) and groped cultivation (4 varieties). Weight, length, width, thickness and specific gravity were greater in the groped cultivation group than in the non-groped. Among the groped varieties, Master 2 showed the greatest values and 76Mo11-3-1-2-2 the smallest. Among the non-groped, weight, length, width and specific gravity were greatest in Jinhong and thickness was greatest in Good Hope and smallest in $79078{\times}ARC$. Hardness showed significant difference only among the non-groped resulting in the lowest value in $79078{\times}ARC$. Fruit sphericity was greater in the non-groped among which Good Hope was the greatest. In fruit color the non-groped showed greater trend in dominant wavelength, especially in Good Hope. No significant difference between group was found in lightness and % chroma. Sugar content showed higher trend in the non-groped and highest in Master 2. Acidity was significantly higher in the non-groped and highest in Good Hope. There was no difference in pH. Vitamin C was difference between group but higher trend in $79078{\times}ARC$. Viscosity was no difference between group but higher trend in $79078{\times}CL1561F6$ of the non-groped and 76Mo11-3-1-2-2-of the groped.

An ecological survey of food and nutrition was conducted in April and May, among 278 children, 6 to 12 years old, of the Youido elementary school, which offers no school lunch program, and is situated in Youido delta of Han River side of Seoul, known as the location of one of the socioeconomically high groups; Eighteen percent and 18.3% of subjects were proven to be overweight and obese, respectively. With regard to frequency of skipping breakfast, 28.4% of the subjects skipped breakfast often and 2.5% of subjects skipped breakfast every morning. Obese children showed good appetite and the time consumed for eating was shorter than those of normal or overweight children. Most serious anxiety among the mothers for those children was food habit of `eating rapidly' and `overeating'. Another striking observation was that 14.4% of the subjects ate only one side-dish with boiled rice, and such a pattern was more often found in the normal or slim group. Most of the subjects had their snacks after being back in home from school. Thirty-one percent of the children had snacks when they felt hungry, 69% had snacks for various reasons such as `habitually', `for unwinding', and `mother gives me snacks'. Thirty-eight percent of the boys and 19% of the girls had physical exercise everyday and overweight and obese children got exercise more frequently. But the time consumed for exercise was much more shorter than that of normal subjects. Most of the children liked fruits, meats, and biscuit, in contrast, lowest preferency was for vegetables, fermented fish products, and boiled rice mixed with other grains. Obese children experienced more kinds of food than normal or slim group. The study found that habits of overeating due to good appetite and eating rapidly were recognized as one of dominant reasons causing obesity among children. On the other hand, serious dietary problem of children of normal or slim group was eating less variety of food. Active nutrition education for both children and mothers will be recommended with joint participation of teachers.
