  • We investigated the quality characteristics of sweet potatoes [Shinyulmi (SM), Yeonhwangmi (HM) and Yunmi (YM) variety] baked and subsequently freeze thawed. Baking was performed with a far infrared radiation oven at $250^{\circ}C$ for 40 minutes. Baked sweet potatoes were frozen at $-18^{\circ}C$ for 30 days, and thawed by a microwave oven for 3 minutes. The crude fat and protein content of HM were higher than the SM and YM varieties. Total sugar, reducing sugar, and free sugar content were increased after baking. Lightness, redness, and yellowness, as well as content of ${\beta}$-carotene, decreased after baking and freeze-thawing. Hardness, gumminess, and cohesiveness decreased during thawing after freezing, except for the YM variety. In a sensory evaluation, appearance, flavor, sweetness and overall acceptance were higher from baking and freeze-thawing the SM variety, instead of the HM and YM variety. From the results, the SM variety is preferred for the production of baked sweet potatoes.

  • This study was conducted to comparatively evaluate antioxidant capacity (AC) of seven cultivars of kiwifruit (Actinidia spp.) and their protective effects on neuronal PC-12 cells. The contents of total phenolics (TP) and total flavonoids (TF) of kiwifruits were also examined. Five cultivars of kiwifruit, Actinidia chinensis (cv. Haehyang and cv. Haegeum), A. eriantha (cv. Bidan), A. arguta ${\times}$ A. deliciosa (cv. Mansoo), and A. arguta (cv. Chiak), were bred in Korea, while two cultivars, A. deliciosa (cv. Hayward) and A. linguiensis (accession number 041AE), originated from New Zealand and China, respectively. Skin extracts of kiwifruit showed higher TP, TF, and AC than flesh extracts. The highest levels of TP and AC were found in cv. Bidan flesh extract among cultivars studied, but the TF content of cv. Bidan flesh extract was the lowest. The kiwifruit bred in Korea had higher AC than their counterparts. AC of kiwifruit had a highly positive linear correlation with TP and TF. The flesh extracts from cv. Hayward, cv. Haehyang, and cv. Haegeum significantly (p < 0.05) prevented PC-12 cells from oxidative stress induced using $H_2O_2$ compared to a control with $H_2O_2$ only. Overall, our results suggest that kiwifruit bred in Korea may offer a good source of antioxidants and serve as functional materials.

  • Citrus is an economically important fruit tree with the largest amount of fruit production in the world. It provides important nutrition such as vitamin C and other health-promoting compounds including its unique flavonoids for human health. However, it is classified into the most difficult crops to develop new cultivars through conventional breeding approaches due to its long juvenility and some unique reproductive biological features such as gamete sterility, nucellar embryony, and high level of heterozygosity. Due to global warming and changes in consumer trends, establishing a systematic and efficient breeding programs is highly required for sustainable production of high quality fruits and diversification of cultivars. Recently, reference genome sequences of sweet orange and clementine mandarin have been released. Based on the reference whole-genome sequences, comparative genomics, reference-guided resequencing, and genotyping-by-sequencing for various citrus cultivars and crosses could be performed for the advance of functional genomics and development of traits-related molecular markers. In addition, a full understanding of gene function and gene co-expression networks can be provided through combined analysis of various transcriptome data. Analytic information on whole-genome and transcriptome will provide massive data on polymorphic molecular markers such as SNP, INDEL, and SSR, suggesting that it is possible to construct integrated maps and high-density genetic maps as well as physical maps. In the near future, integrated maps will be useful for map-based precise cloning of genes that are specific to citrus with major agronomic traits to facilitate rapid and efficient marker-assisted selection.

  • This study aims to prove the changes, development and social background of Korean male cosmetics over the period of 2000-2010. There were total 574 articles written about male make-up and cosmetics in Chosun Daily, Joongang Daily and Donga Daily, which are the top three Korean local daily newspapers in terms of sales revenue for that period. These articles were analyzed together with social background research from various books and daily newspapers. The analysis of articles was divided into different categories; such as foundation cosmetics, color cosmetics, hair, and the social background. It was found that the articles related to foundation cosmetics were written the most, the articles related to male appearance management were second, articles on other items including how to manage the skin being the least. As for the social background of Korean male cosmetics, first of all, a change in social recognition can be pointed out. The traditional understanding of gender roles has changed, men's appearance management has started to be regarded as a competitive talent, and at the same time, the esthetic viewpoint for men also has changed. One example is the newly made popular term, "flower-handsome man", which shows the new trend of favoring males with nice skin. Second, the expansion of mass culture can be pointed out. As consumers can get information and fashion trends easier and faster, the fashion spreads fast, and this has led to the generalization and popularization of the sense of beauty. Third, the development of scientific technology and medical science can be pointed out. Thanks to the progress in those areas. the extension of youthfulness has become possible and the cosmetics industry was also affected greatly, as shown in the market spread of functional products for anti-ageing and wrinkle control as the interest in anti-ageing has grown. There are benefits from the development of scientific technology, but the problem of environmental pollution has appeared due to machinery and industrialization and thus the issue of well-being has been raised. Rising interest in naturalism, pro-environmentalism and organic cosmetics has influenced the cosmetics industry. In addition, the quantity of ultraviolet rays exposed to our skin has increased due to the air pollution caused by the destruction of environment, leading to increased usage of sun block lotion. Lastly, the influence of consumer society and the expansion of consumerism culture can be pointed out. In the modern society, consumption acts not only as the use of products and services but it also has an important role of mediating individuals with others and the society. The market for male cosmetics has been expanding and the number of men putting on make-up has been increasing rapidly. Therefore, this study is meaningful in that the analysis of the mode of change and the social background are an essential process in order to provide a direction for the future market for male cosmetics.

  • The growth characteristics and the Germanium (Ge) uptake of rice plant (Hopyungbyeo) in soil with Ge were investigated under different soil textures to obtain the basic information for agricultural utilization of Ge. This study was carried out in the Wagner pot ($15,000^{-1}a$). Ge concentration in soils such as clay loam, silt loam, loam and sandy loam for rice plant cultivation was treated at $8mg\;kg^{-1}$. The growth status of rice plant was almost similar in all soil texture, and rice yield was higher in the order of silt loam > clay loam > loam > sandy loam. In rice bran, the Ge uptakes in silt loam, clay loam, loam and sandy loam were 980, 868, 754 and $803{\mu}g\;pot^{-1}$, respectively. The Ge uptakes of brown rice and polish rice were greater in the order of silt loam > sandy loam > clay loam > loam. In silt loam, the Ge uptake rates in leaf, stem, root, rice bran and brown rice were 19.7, 2.3, 0.03, 3.1 and 0.44%, respectively. Therefore, under the given experimental condition the optimum soil texture for production of functional rice with Ge is a silt loam.

  • Improvement of heat sink technology related to the continuous implementation performance and extension of device-life in circumstance of easy heating and more compact space has been becoming more important issue as multi-functional integration and miniaturization trend of electronic gadgets and products has been generalized. In this study, it purposed to minimize of decline of the heat diffusivity by gluing polymer through compounding of inorganic particles which have thermal conductive properties. We used NH-9300 as base resin and used inorganic fillers such as silicon carbide(SiC), aluminum nitride(AlN), and boron nitride(BN) to improve heat diffusivity. After making film which was made from 100 part of acrylic resin mixed hardener(1.0 part more or less) with inorganic particles. The film was matured at $80^{\circ}C$ for 24h. Diffusivity were tested according to sorts of particles and density of particles as well as size and structure of particle to improve the effect of heat sink in view of morphology assessing diffusivity by LFA(Netzsch/LFA 447 Nano Flash) and adhesion strength by UTM(Universal Testing Machine). The correlation between diffusivity of pure inorganic particles and composite as well as the relation between density and morphology of inorganic particles has been studied. The study related morphology showed that globular type had superior diffusivity at low density of 25% but on the contarary globular type was inferior to non-globular type at high density of 80%.

  • The goal of this study was to develop a high value Korean red wine possessing antihypertension activity. The effects of some medicinal plants and grapes on the alcohol fermentation process and the angiotensin I-converting enzyme (ACE) inhibitory activity of Vitis hybrid red wine were investigated. Various Vitis hybrid red wines were vinified by the fermentation of a mixture of Vitis hybrid must and some medicinal plants and grapes at $25^{\circ}C$ for 10 days. Of these red wines, the Vitis hybrid-Vitis coignetiae red wine exhibited a high ethanol content of 12.0% and had a good level of acceptability. It also showed a high antihypertensive ACE inhibitory activity of 68.5%. After post-fermentation of 60 days, the ACE inhibitory activities of the Vitis hybrid-Vitis coignetiae red wine exhibited the highest ACE inhibitory activity of 80.7% ($IC_{50}$: 28 mg/mL) and also had the best acceptability. The $C_{18}$ solid phase extracts of the Vitis hybrid-Vitis coignetiae red wine, after 60 days post-fermentation, showed clear antihypertensive effects on spontaneously hypertensive rats. Our results reveal that the Vitis hybrid-Vitis coignetiae red wine has the potential to become a new functional red wine due to its good acceptability and high antihypertensive activity.

  • Among the various contemporary issues that confront the nation or society, surely one of the most difficult to resolve are environmental disputes between government authorities, developers, local residents and advocacy groups. While such disputes can in some cases be the result of a selfish and illegal NIMBY("Not In My Back Yard") syndrome, they can also be an expression of rational and appropriate demands from local residents to preserve the ecology and quality of life for their communities, particularly with respect to the planning of "locally unwanted land uses(LULUs). Accordingly, rethinking NIMBYism entails several implications for planning of LULUs. Until the 20th century many planners considered only "functional rationality" in their decision making, in a confrontational "us versus them"process of "decide-announce-defend(DAD)". I believe, however, that a fair, voluntary, and negotiated process of alternative dispute resolution(ADR) based on consensus building is the means to resolving these disputes. A voluntary process is more desirable and feasible than a coercive one, making ADR well worth pursuing. From this perspective, I explore several factors which affect the resolution of environmental disputes. I suggest three main factors as follows: i) extension of citizen participation, ii) enhancement of equity, and iii) building of trust. Alternatives are presented based on these factors.

  • In order to improve the storage stability of steamed bread, fermented pine needle extract syrup potentially with several functional properties was added in manufacturing the products at levels of 8.3, 11 and 18% based on Brix degree of the dough. The manufactured bread was stored at ambient conditions and measured for quality attributes. Dough added with the fermented pine needle extract syrup maintained its pH and water activity at levels of $5.45{\sim}5.90\;and\;0.94{\sim}0.96$, which are normally suitable for yeast fermentation and for appropriate dough hardness. Addition of the extract syrup increased the bread volume by more than 20%. The bread with higher content of the pine needle extract syrup showed slower increase of bread hardness during storage, suggesting retardation of bread retrogradation. The addition of the pine needle extract syrup in bread dough also inhibited growth of the aerobic bacteria and molds on the bread surface (by $0.8{\sim}24$ in log (CFU/g) at 4 day storage). Use of higher than 11% concentration presented initially a strong fine needle flavor to the bread, which disappeared soon after 2 days. Generally addition of the pine needle extract syrup did not give negative effects on the bread quality including sensory quality. Therefore, the addition of the needle extract syrup could contribute to improving the storage stability and extending the shelf life of the bread.
