Traditional market is a place filled with traditional culture and sentiments of the local population, so this is not just a commodity trading places that has been at the centre of our life, including culture and the local economy and the people of the community. However, many consumers still ongoing by the facilities that aging is deprived to the department stores and hyper-marts. Also, low awareness of the displayer, including the internal facilities, is very reality is bad development compared to the appearance, in particular product names, price tags and one mark of origin, such as signs, despite Upon entering the market first leaps to the eye are not improved the situation as it is necessary for the improvement of typography for traditional market. Therefore, examine the fonts used in the traditional markets, proceed to further analysis in the future by building a dedicated font made of only the traditional market it has a distinctive identity and unity of the market typography to present the guidelines of the market font.

Fine dust is one of the top ten causes of deaths globally. More than 95% of the world's population are endangered by it. However, as the fine dust problem is difficult to address immediately, people should be informed of its risk and prepared to deal with it. This study explores the methods used to define, efficiently provide, and manage the complementary relationships between various types of media providing risk information utilizing the competitive characteristics of media in niche theory. A survey consisting of 348 Korean university students was conducted over 12 days, to analyze three factors: consumer perception of fine dust, media usage, and media use gratification. The response value for media gratification was substituted in the equation to derive the niche breadth, niche overlap, and competitive superiority. It was found that 1) for providing fine dust forecast and fine dust response guidance information, a smartphone application was the most effective; 2) smartphone applications were limited in providing additional information such as the severity and origin of fine dust, and hence, it is necessary to establish the functionality of the Internet and TV to complement smartphone applications. Thus, a system considering the above should be developed.

A deteriorating North Korean economy, coupled with a devastating natural disaster such as flooding and drought in recent years, brought about a severe food shortage and malnutrition problem which caused a migration of its population including young children to neighboring countries. We conducted a nutritional survey on a total of 436 children, aged 4-19 years old, who migrated to the China side of the border from July to September, 1999. The study subjects were interviewed by Korean-Chinese interviewers who were trained for anthropometric measurements and dietary surveys. Heights, weights, and chest circumference of the subjects were 70-90% of the South Korean reference values for the corresponding age and sex. Dietary intakes of the subjects were found to be extremely poor-the average number of food, mostly of plant origin, consumed in a day was 2.8, and the proportion of the subject who reported to take all three meals in a day while residing in North Korea was as low as 36.2%. Ninety five percent of the subjects had at least one clinical symptom related to malnutrition, 68.6% had 2-4 symptoms, and 15.1% had 5 or more symptoms. The results of this study provided an objective data for the first time on the severity of the food crisis and malnutrition problem that afflicted North Korean older children and adolescents as well as children aged 7 or under as previously reported elsewhere. the wasted and stunted children and youths prevailing in North Korea could exert a negative influence on the country's health and economy. More researches are needed in the future to investigate on the impact of malnutrition in North Korean children on the country's social, economic, and cultural state as well as on the health and nutrition situation.

The number of diabetics in Korea is about 3 to 5 percent of the population, and the incidence is increasing yearly due to changes of life style and food intake. Diet is a key element in the management of diabetes, yet the appropriate diet for diabetes remains controversial. We have recently shown that a diet rich in protein of animal origin(casein) seems beneficial to controling plasma glucose and lipids in streptozotocin-induced diabetic rats. It therefore seemed desirable to find out whether the beneficial effect of high casein diet in experimental diabetes could also be reproduced with a vegetable source of protein(soy). The purpose of this study is to compare these results with the results of our previous study. In the present study, non-diabetic and streptozotocin-induced diabetic rats were studied in order to examine the effects of altering the level(20% vs 60%) of dietary soy protein on blood glucose, lipids, and hormones. Results of the present study showed that a high soy protein diet decreased triglyceride concentration in diabetic rats. However, diabetic rats fed a high soy protein diet were not hypocholesterolemic compared to rats fed a control diet. Moreover, diabetic rats fed a high soy protein diet had significantly increased plasma glucose concentration compared to rats fed a control diet. This study was not able to discern a specific effect of dietary protein level on insulin, glucagon, or insulin/glucagon ratio. Except for the hypotriglyceridemic effect, the results were not similar to the findings of our previous study which showed a beneficial effect on streptozotocin-induced diabetic rats fed a high casein diet.

Fifteen populations comprising three taxa and a putative hybrid of Fallopia sect. Reynoutria in Korea were examined for their leaf flavonoid constituents. Nineteen flavonoid compounds were isolated and identified; they were glycosylated derivatives of the flavonols quercetin and kaempferol, and of the flavones apigenin and luteolin. Among them, quercetin 3-O-galactoside and quercetin 3-O-glucoside were major flavonoid constituents, and present in all taxa. The flavonoid data appear to be very useful for taxon delimitation, and all taxa examined are readily distinguished by their flavonoid profiles. In addition, the flavonoid data suggest that the Nonsan population may be of hybrid origin involving F. japonica var. japonica, F. forbesii, and F. sachalinensis. In F. japonica var. japonica, there is no apparent correlation between their levels of polyploidy and flavonoid chemistry, but geographical variation of the flavonoid profiles among some populations was detected.

Background: Chronic lymphoid leukemia (CLL) is not an uncommon hematological malignancy which primarily affects elderly individuals. It is more common in developed world than in developing countries. The rational of this study was to determine the clinico-hematological profile in Pakistan. Materials and Methods: In this prospective cross sectional study, sixty patients with CLL were enrolled from January 2011 to June 2013. Data were analyzed with SPSS version 21. Results: The mean age was $59.0{\pm}9.2years$ (range 40-82) and the male to female ratio was 2.1:1. Peak age group was 60-70 years (38.3%) and 18.3% were under 50 years old. Major complaints were weakness (51.7%), fever (18.3%) and abdominal discomfort (13.3%). Main clinical findings were splenomegaly (46.6%), lymphadenopathy (36.6%) and pallor (26.7%). Some 16.7% were diagnosed incidentally. The mean hemoglobin was $10.8{\pm}2.4g/dl$, with a total leukocyte count of $91.5{\pm}87.8{\times}10^9/l$ and platelets $197.8{\pm}103.2{\times}10^9/l$. Anemia and thrombocytopenia were seen in 26.7% and 21.7% of cases, respectively. High LDH and hyperuricemia were detected in 15% each and elevated serum creatinine was seen in 11.6%. According to Rai staging 11.6% were in stage 0, 13.3% stage 1, 26.7% each for stage II and stage III while 21.7% patients were in stage IV. Conclusions: CLL in our patients in Pakistan, unlike in the West, is seen in a relatively young population with male predominance. Primarily disease is of B-cell origin and about 2/3 of the patients present at advanced stage.

Background: The prevalence of non-squamous cell malignant tumors of the oral cavity has not been evaluated in Iran extensively. The aim of this study was to evaluate epidemiological aspects of the oral malignancies with non-squamous cell origin during a 43-year period in the Faculty of Dentistry, Mashhad University of Medical Sciences, Iran. Materials and Methods: In this retrospective study, the records of all patients referred to dental school of Mashhad university of medical sciences in northeast of Iran, during the period 1971-2013 were evaluated. All confirmed samples of oral non squamous cell malignant tumors were included in this study. Demographic information including age, gender and location of the lesions were extracted from patient's records. Data were analyzed using SPSS statistical soft ware, Chi-square and Fisher's exact tests. Results: Among 11,126 patients, 188 (1.68%) non squamous cell malignant tumors were found, with mean age of 39.9 years ranging from 2 to 92 years. The most common tumors were mucoepidermoid carcinoma (33 cases) and lymphoma (32 cases). Non squamous cell malignant tumors occurred almost equally in men (94 cases) and women (93 cases). Most (134 cases) of them were located peripherally with high frequency in salivary glands (89 cases) and 52 cases were centrally with high frequency in the mandible (38 cases). Conclusions: More findings in this survey were similar to those reported from other studies with differences in some cases; it may be due to variation in the sample size, geographic and racial differences in tumors.

Dioxins are chemical substances that are not properly decomposed degradation under natural photochemical, biological and chemical conditions in the environment, and bio-accumulate through the food chain, so pose a risk of causing adverse effects to human health and the environment. Ninety seven percent of human exposure to dioxins comes through meat, fish, dairy consumption and so on. Pork is the largest proportion meat aspect of daily intake in the Korean food. Pigs are three times more than Cattle in terms of breeding population and production amount in the world, and the amount is increasing every year. Therefore, it is necessary to monitor the exposure level of dioxins in pig's body. Also, it is required to evaluate the presence of these chemical substances in the pig's feed grain such as corn, soybeans, and tallow. The purpose of this study was to evaluate PCDD/Fs in pig's feed to search the origin of PCDD/Fs. Feed samples obtained were wheat from East Europe, corn from South America and America, soybean meal from Korea, America, South America and India and tallow from Korea. The preparation of samples was based on the EPA method 1613. Instrumental analysis was based on the use of high resolution gas chromatography coupled to high resolution mass spectrometry (HRGC/HRMS). The concentrations of 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD) and 1,2,3,7,8-pentachlorodibenzo-p-dioxin (PCDD), which are the most toxic potent dioxins, were not observed in any of the samples. However OCDD was detected in most of the samples. The TEQs in the feed samples were ranged from 0 pg TEQ/g to 0.09841 pg TEQ/g. Especially, the high level of TEQs was observed in the samples of wheat from East Europe and soybean meal from Korea.

Objectives: To determine the relationships between physical activity (PA), the neighborhood environment support for PA, and social support for PA among Mexican-American women living in South Texas. The Enlace study was a randomized controlled trial that tested the effectiveness of a promotora-led PA intervention among low-income Mexican origin women (n=614) living in colonias. Methods: The dependent measures included accelerometer-measured average moderate to vigorous physical activity (MVPA) and sedentary breaks and the Community Health Activities Model Program for Seniors PA 41-item questionnaire. The independent measures included the Physical Activity and Neighborhood Environment Scale (PANES) and the 13-item Physical Activity Social Support (PASS) scale. Results: Enlace participants were on average 40.4 (standard deviation, 10.3) years old, born in Mexico (86.1%), and uninsured (83.1%). Adjusted linear regression results indicated that each 1-point increment in the PANES overall score was associated with 0.050 (p<0.001) unit increase in sedentary break and a -0.043 (p=0.001) unit decrease in sedentary break duration. Both PANES (${\beta}=0.296$; p=0.002) and PASS scores (${\beta}=0.076$; p<0.001) were associated with weekly average self-reported MVPA. Interaction effects were observed between PASS scores and accelerometer-measured frequency of sedentary breaks and sedentary time duration. Conclusions: The findings of this study indicate that the relationships between PA and built environment and social support are measure-dependent and suggest that reducing sedentary time in this population may require a closer assessment of social support for PA.

Density functional theory (DFT) and time-dependent density functional theory (TDDFT) calculations, employing the B3LYP method and the LANL2DZ, 6-31G$^*$(LANL2DZ for Tc), 6-31G$^*$(cc-pVDZ-pp for Tc) and DGDZVP basis sets, have been performed to investigate the electronic structures and absorption spectra of the technetium-99m-labeled methylenediphosphonate ($^{99m}Tc$-MDP) complex of the simplest diphosphonate ligand. The bonding situations and natural bond orbital compositions were studied by the Mulliken population analysis (MPA) and natural bond orbital (NBO) analysis. The results indicate that the ${\sigma}$ and ${\pi}$ contributions to the Tc-O bonds are strongly polarized towards the oxygen atoms and the ionic contribution to the Tc-O bonding is larger than the covalent contribution. The electronic transitions investigated by TDDFT calculations and molecular orbital analyses show that the origin of all absorption bands is ascribed to the ligand-to-metal charge transfer (LMCT) character. The solvent effect on the electronic structures and absorption spectra has also been studied by performing DFT and TDDFT calculations at the B3LYP/6-31G$^*$(cc-pVDZ-pp for Tc) level with the integral equation formalism polarized continuum model (IEFPCM) in different media. It is found that the absorption spectra display blue shift in different extents with the increase of solvent polarity.
