This study will analyze the economic impact on villages adjacent to recreational areas in natural forests with the goal of creating a forest development plan. The area of study has been limited to the National Natural Recreation Forest and the twelve adjacent villages around the area. The collected data used a SPSS. 12.0 frequency and cross, t-test and ANOVA analysis was performed. To questions regarding increase in income and employment due to recreational areas in natural forests, there were some in all three areas that responded that it did not contribute to increases in income or employment. In all areas, there were respondents who think that these recreational areas do not help increase awareness of their nearby towns. Facilities, in order from most used to least used were tourist sites, lodgings and then food and meals. The level of satisfaction of customers in all areas was low with reasons being low quality of goods, not knowing the village(s) well, a lack of specialty items, and poor roads. In conclusion, this study presents a development plan based on the derived research results.

Obese postmenopausal women increase their risk of developing breast cancer (BC), in particular if they display an android-type pattern of adiposity, which is also associated to increased risks of diabetes mellitus, hypertension and cardiovascular disease. In order to explore the associations among anthropometry (body mass index, body composition, somatotype), some specific items of medical history (diabetes, hypertension, dislypidemias, hyperuricemia) and the risk of BC in Uruguayan women, a case-control study was carried out between 2004-2009 at our Oncology Unit. 912 women of ages between 23-69 years (367 new BC cases and 545 non hospitalized, age-matched controls with a normal mammography) were interviewed. Twenty body measurements were taken in order to calculate body composition and somatotype. Patients were queried on socio-demographics, reproductive history, family history of cancer, a brief food frequency questionnaire and on personal history of diabetes, dislypidemias, hyperuricemia, hypertension and gallbladder stones. Uni- and multivariate analyses were done, generating odds ratios (ORs) as an expression of relative risks. A personal history of diabetes was positively associated to BC risk (OR=1.64, 95% CI 1.00-2.69), being higher among postmenopausal women (OR=1.92, 95% CI 1.04-3.52). The risks of BC for diabetes in postmenopausal women with overweight combined with dislypidemia (OR=9.33, 95% CI 2.10-41.5) and high fat/muscle ratio (OR=7.81, 95% CI 2.01-30.3) were significantly high. As a conclusion, a personal history of diabetes and overweight was strongly associated to BC. The studied sample had a subset of high-risk of BC featured by postmenopausal overweight and diabetic women, who also had a personal history of hypertension and/or dyslipidemia. The present results could contribute to define new high risk groups and individuals for primary as well as for secondary prevention, since this pattern linked to the metabolic syndrome is usually not considered for BC prevention.

Polyunsaturated fatty acids (PUFA), especially eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) have significantly beneficial effects on health in relation to cardiovascular, immune, and inflammatory conditions and they are involved in determining the biophysical properties of membranes as well as being precursors for signaling molecules. PUFA biosynthesis is catalyzed by sequential desaturation and fatty acyl elongation reactions. This aerobic biosynthetic pathway was thought to be taxonomically conserved, but an alternative anaerobic pathway for the biosynthesis of PUFA is now known to contain analogous polyketide synthases (PKS). Certain fish oil can be a rich source of PUFA although processed marine oil is generally undesirable as food ingredients because of the associated objectionable flavors that are difficult and cost-prohibitive to remove. Oil-seed plants contain only the 18-carbon polyunsaturated fatty acid alpha-linolenic acid, which is not converted in the human body to EPA and DHA. It is now possible to engineer common oilseeds which can produce EPA and DHA and this has been the focus of a number of academic and industrial research groups. Recent advances and future prospects in the production of EPA and DHA in oilseed crops are discussed here.

CYP1A1 is known to be inducible by xenobiotic compouds such as polyciclic aromatic hydrocarbons(PAHs) and 2,3,7,8-tetrachloro-dibenzo-p-dioxin(TCDD). These chemicals have been identified worldwide and can have a significant impact on the human health and well being of human and wildlife. Given these issues, the detection and quantification of these chemicals in biological, environmental and food samples is important. First, we investigated the effect of on CYP1A1 promoter activity, 7-ethoxyresorufin-O-deethylase(EROD) activity and CYP1A1 mRNA expression induced by benzo(k)fluoranthene(B(k)F) in MCF-7 cells. We found that B(k)F significantly up-regulates the level of CYP1A1 prompter activity, EROD and CYP1A1 mRNA. When cells were treated with genistein, it was not changed that EROD and CYP1A1 mRNA, compared to that of control. However, genistein inhibited the B(k)F-induced CYP1A1 promoter activity and mRNA level at high concentration. Furthermore, in this study, effects of HDAC(histone deacetvlase) inhibitors on human prostate cancer cells proliferation were examined. HC-toxin, SAHA and TSA inhibited cell proliferation in PC3 cells. A novel HDAC inhibitor, IN2001 also suppressed the growth of PC3 cells. And IN2001 and SAHA increased S phase and G2/M phase at 12 hrs treatment but cells were arrested G0/G1 phase at 45 hrs treatment. The HC-toxin treatment for 24 hrs and 48 hrs increased G0/G1 at low concentration ($0.1\mu\textrm{m}$) but increased G2/M at more than concentration of $1\mu\textrm{m}$. TSA increased G2/M phase. These findings height the possbility of developing HDAC inhibitors as potential anticancer therapeutic agents for the treatment of prostate cancer.

Recently, the health-promoting effects of functional foods have been shown to prevent nutrition-related diseases, improve physical and mental well-being, satisfy hunger, and provide necessary nutrients for the human body. Koumiss is a common type of fermented mare's milk that has been shown to have beneficial therapeutic effects on cardiovascular disease, tuberculosis, and diarrhea as it can nourish vessels, relieve ill mood, and improve digestion. Hence, in this study, we aimed to prepare health-promoting koumiss using different concentrations of flaxseed (Linum usitatissimmum L.), which has the potential to control heart disease, hypertension, inflammation, and lung function. The pH was decreased to around 4.42-4.43, whereas the total anthocyanin (TA) content was increased to around 0.78~0.82% after fermentation of the koumiss premix. There were no significant differences in pH and TA among the three groups, including the control group. In sensory profile analysis, the taste, flavor, color, texture, and overall acceptability decreased in proportion to the added amount of flaxseed. These findings provided the first data describing the effects of flaxseed on koumiss fermentation, establishing a basis for commercial-scale production of koumiss containing fermented flax seed and for improving the health-promoting activity of koumiss.

The principal objective of this study was to evaluate the chemopreventive and therapeutic effects of a combination of all-trans-retinoic acid (RA) and knockdown of delta-like 1 homologue (Drosophila) (DLK1) on neuroblastoma, the most common malignant disease in children. As unfavorable neuroblastoma is poorly differentiated, neuroblastoma cell was induced differentiation by RA or DLK1 knockdown. Neuroblastoma cells showed elongated neurite growth, a hallmark of neuronal differentiation at various doses of RA, as well as by DLK1 knockdown. In order to determine whether or not a combination of RA and DLK1 knockdown exerts a greater chemotherapeutic effect on neuroblastoma, cells were incubated at 10 nM RA after being transfected with SiRNA-DLK1. Neuronal differentiation was increased more by a combination of RA and DLK1 knockdown than by single treatment. Additionally, in order to assess the signal pathway of neuroblastoma differentiation induced by RA and DLK1 knockdown, treatment with the specific MEK/ERK inhibitors, U0126 and PD 98059, was applied to differentiated neuroblastoma cells. Differentiation induced by RA and DLK1 knockdown increased ERK phosphorylation. The MEK/ERK inhibitor U0126 completely inhibited neuronal differentiation induced by both RA and DLK1 knockdown, whereas PD98059 partially blocked neuronal differentiation. After the withdrawal of inhibitors, cellular differentiation was fully recovered. This study is, to the best of our knowledge, the first to demonstrate that the specific inhibitors of the MEK/ERK pathway, U0126 and PD98059, exert differential effects on the ERK phosphorylation induced by RA or DLK1 knockdown. Based on the observations of this study, it can be concluded that a combination of RA and DLK1 knockdown increases neuronal differentiation for the control of the malignant growth of human neuroblastomas, and also that both MEK1 and MEK2 are required for the differentiation induced by RA and DLK1 knockdown.

The purpose of this study was to investigate the elementary school teacher's status and recognition of nutrition education (NE) in Incheon. A cross-sectional study was carried out using a self-administered questionnaire and subjects were 147 elementary school teachers. The results are as follows. Only 9.5% of the teachers had training in NE and 71.4% of the teachers with training increased concern about NE after training. As for experience of NE, 61.6% of the teachers experienced NE and more than half of them gave NE less than twice per month. There was a significant difference in reason for not giving NE between subgroups by teaching career; 57.7% of the teachers with career more than 10 years did not give NE due to too much other work. As for existence of nutrition educator in school, 48.9% of the teachers recognized its existence and 91.3% of them answered that dietitians have done NE. For correction of unbalanced diet, good table manner, and nutrition and growth, 97.9% of the teachers answered that NE is necessary in elementary school. As for proper time to start NE, 57.5% of the teachers answered kindergarten and 39,7% answered lower grade of elementary school. As for effective type for NE, 47.3% of the teachers answered NE as a part of other subject and 28.1 % answered NE as a separate subject. Also 69.8% of the teachers answered dietitian as suitable person for NE. As for newly establishing a NE subject, 37.9% of the teachers disagreed and as for most effective method for NE, 73.3% answered NE linked with school lunch program. Most of teachers recognized elementary school students' eating habit problem severe and change of their eating habit such as various food choice, no plate waste and good table manner after school lunch program. Therefore, it should be nationally supported that a standardized NE program is developed and coordinated among teachers, school lunch dietitian as NE specialist, family and community for elementary students' health and well-being.

Curcuma longa L. (turmeric) is an important medicinal plant that has been historically used in herbal medicine and in the health food throughout Asia etc. Recently, the demands on rhizome of turmeric are increasing greatly by well-being boom, but there is not enough to meet the demands. To fulfill increasing demands, cultivation system strategies using the organic fertilizers are required to produce a greater amount of rhizome with good quality and yield. A field experiment was conducted to determine the effect of composts, NPK fertilizer(control, F), NPK + swine manure(SM) and NPK + fermentation manure from the wasted oriental medicine materials(OMWM), on rhizome yield and the content of bioactive components for quality. Our results showed that two compost applications can increase both rhizomes(24.1-25.9%) and curcumin(21.7-41.0%) yields, respectively, compared to F control. The content of amino acids increased significantly by SM and OMWM treatments. SM and OMWM application also increased the total phenol yields 7.8 and 8.7 g/10a compared with control 6.3 g/10a, the flavonoid yields 6.3 and 7.3 g/10a compared with control 5.3 g/10a, and also antioxidant activity 21.7 and 41%, respectively, as compared to the control. Especially, OMWM was more effective in total rhizomes yields and bioactivities and in the biosynthesis of curcumin and bioactive components than SM treatments, but the biological pathway was not clear, still. This experiment suggests that curcumin or bioactive components affected by adding SM and OMWM could increase the yields and quality of turmeric.

An assortment of daily supplies have been documented in and accounting book that Hwa-sun Song, a wholesale dealer in Hongcheon, Gangwon-do, sent to Young-hui Sin, a customer. This study analyzed a total of 163 documentations in the accounting book between 1910 to 1916, which includes types of daly supplies, trading volume, and prices, maintained accounting between. Consequently, we are able to indentify companies that produced the applicable goods, names of products, units by which goods were counted, and the lowest and highest prices prevailing, along with kinds of goods patronized in everyday life in Hongcheon in the early 20th century. Paper had the maximum trading volume. The second, most traded were cigarettes, a symbol of the new culture. These were traded under various brand names, such as Kkotpyo, Guksyu, Sanhopyo, Syonghak, and Joil. Foodstuffs, were the third most traded items, including fish, fruits, sugar, Waeddeok, Chilwaeddeok, Color candies and Okchyun candies. Our results indicate that the snack food business had developed since the 19th century. Lighting equipment, oil, candles, matches as well as traditional oil lamps and flints cornered the fourth largest stock being traded. Medications were fifth, with prescriptions written for Insohwan, Hoechyungsan and Siungo, including quinine, a medicine for malaria. Other trades included kitchen appliances such as soup bowls, porcelain bowls, kettles, and drinking cups, and a variety of daily supplies such as mirrors, mats, umbrellas, Geumjiwaemil, hair oil imported from Japan, and soap.
