The external factors of global flavor market include the world economy, population growth, urbanization, consumer spending, raw material availability, pricing, and regulatory issues. And the internal factors as product pricing and technology development may lie the flavor house's competitiveness and cost considerations. In developing countries, rising preference for packaged food and beverages and increasing personal expenditures will drive demand for flavor market. Increasing consumer demand for natural products, driven in part by health concerns and a desire for transparency in labeling will impact the demand. The increasing demand for salt and sugar reduction will boost demand for flavors to maintain the overall taste. The use of quality and innovative flavors in the beverages and the multifunctional flavors has a positive influence on the global market. The global flavor industry has the presence of several drivers and positive trends, with its future expected to be promising.

Objective: Pituitary adenylate cyclase-activating polypeptide (PACAP), a novel hypothalamic neuropeptide, has been suggested to play a role in ovarian folliculogenesis. The present study evaluated the effect of PACAP on the growth of preantral follicles. Methods: Preantral follicles were mechanically isolated from ovaries of 21-day-old rats and cultured in groups for 3 days in serum-free medium in the absence or presence of PACAP-38 ($10^{-6}M$). Results: Treatment with PACAP-38 resulted in an increase in follicle diameter by 75% whereas treatment with follicle stimulating hormone (FSH) increased follicle diameter by 65%. PACAP-38 treatment enhanced the granulosa cell proliferation as measured by thymidine incorporation analysis. Furthermore, the production of progesterone by cultured granulosa cells and GFSHR-17 cell line was stimulated by PACAP-38. Interestingly, PACAP enhanced FSH action on stimulation of SF-1 and aromatase gene expression. Conclusion: The present results demonstrate that PACAP stimulated preantral follicle growth by potentiating proliferation and by stimulating steroidogenesis.

Introduction : Chronic hemodialysis patients have been psychological problems because of being compelled to follow a dialysis schedule for a long period of time. Specifically, depression and anxiety are so frequently observed that psychological management is required for most hemodialysis patients. Fragrance has been known to have beneficial psychological and physiological effects on human. This study was designed to investigate the psychological effect of aromatherapy on chronic hemodialysis patients. Methods : 40 subjects of this study selected from Je Young-Sung Internal Medicine Clinic in Busan. The experimental group were random assigned to 20 subjects who had visited on Monday, & Wendesday & Friday and received aromatherapy every day for 2 weeks. the control group were random assigned to 20 subjects who had visited on Tuesday & Thursday & Saturday and did not receive any intervention. Experiment had been conducted from July. 7th July 21, 2003 and anxiety by Spilberger's state anxiety scale and depression by Zung's Scale were measured in the course of aromatherapy for both experimental group and control group. A control period consisting of natural hospital smells was established before each test session, and then aromatic test conditions were systematically evaluated for odorless conditions as well as aromatic conditions containing 100% lavender necklace for 2 weeks. Data were analyzed by, frequency, percentage, mean, S.D. $x^2$- test, t-test. Results:1) Anxiety scores were not significantly decreased in the experimental group($54.57{\pm}13.20$) after treatment compared to the control group($49.45{\pm}12.41$)(t=1.225, p=.228). 2) Depression scores were significantly decreased in the experimental group($43.95{\pm}5.63$) after treatment compared to the control group($49.65{\pm}9.84$)(t=-2.367, p=.023). Conclusions : These findings indicate that the aromatherapy may decreased depression. It is suggested that the aromatherapy could be an effective nursing intervention to reduce to depression by chronic hemodialysis patients.

This study investigated the brewing properties of rice beer made with yeast isolated from traditional whole wheat nuruk. The experimental method was followed by alcohol fermentation and quality analysis for six months after separating the yeast from nuruk. The yeasts isolated from traditional nuruk showed normal fermentation characteristics, like those of commercial yeast, in terms of alcohol production capability, sugar content, and pH reducing power. Especially, the yeast (KCCM 301) isolated from whole wheat nuruk showed higher contents of glycogen and trehalose than that of commercial yeast, and so KCCM 301 yeast has excellent yeast vitality. Meanwhile, the yeast (KCCM 90301) isolated from traditional Nuruk produced significantly higher alcohol and ester contents than that of commercial yeast. This has a positive effect for supplementing the taste and aroma of rice beer. In conclusion, the yeasts isolated from whole wheat nuruk showed the general alcohol fermentation pattern and aroma content of rice beer. These yeasts seem to be effective in strengthening the flavor of rice beer.

The effects of aroma mixed oil with Chamomile, Lavender and Sandalwood on atopic dermatitis in NC/Nga mice were examined. The NC/Nga mice were divided into BMAC group, FK 506 Oinment (Tacrolimus Hydrate) group, and CLS group to get curative power of CLS. The amount of total IgE and IgG1 was measured and the severity of atopic dermatitis was assessed by the scoring procedure in NC/Nga mice. Topically applied CLS significantly suppressed the level of serum IgE and IgG1 in NC/Nga mice and FK506, used as reference drugs for atopic dermatitis, also exhibited suppressive effects against level of IgE and IgG1. The level of IgE was lower in the CLS group than in the FK506 group while the serum IgG1 level in the FK506 group was lower than in the CLS group. The treatment with FK506 and CLS reduced the skin inflammation index, especially the severity degree of atopic dermatitis in the skin lesioned NC/Nga mice by naked eyes was improved by treatment of FK506 and CLS. The results suggest that treatment of CLS in NC/Nga mice with atopic dermatitis have an beneficial therapeutic effects on reducing the level of IgE and IgG1 and accelerating repair of skin lesion.

This study was tested on Ratafia Champagne Trouillard 1947 of old fortified wine and analyzed differences from existing wines. Old fortified wine in Champagne, France and blanding is Pinot Noir, Chardonnay and Pinot Meunier. Alcohol level is 18% and test date is Feb. 15-21, 2019(six days of decanting period/15 p.m. on the last tasting day). Tester is composed of one FICB grand commander one KOV Finland commander. The wine opening was tested for two blades after wire removal and the decanting time was applied to the calculation formula of 2019(this year)-1947(vintage year)/12=6 days set in this study. Aroma smelled like cherries, fruits, soy sauce and licorice and bouquet was identified in five stages. The first stage was presented with the smell of pot, the second stage was light coffee, the third stage smell of fruit and flowers, the fourth stage smell of wild honey and the fifth stage smell of refined brandy. Then, the test was analyzed in seven stages. This study has the following implications: First, the new concept of old wine was applied to fortified wine. Specific computational formulas for the decanting period were derived. The decanting presented five steps of aromas and bouquet. Wine testing has been expanded from the previous five to seven levels. A new taste of Champagne old fortified wine was analyzed.
