The physicochemical properties and antioxidant activities of commonly consumed espresso and regular coffees, at coffee shops in downtown Seoul, were investigated. Moreover, the characteristics between chain type coffee shop and owner shops were compared using t-tests. The serving temperature and volume of espresso were lower than those for regular coffees. Whereas, the pH and total acidity of espresso were higher than those for regular coffees. Coffees from chain shops, in particular, had a significantly higher pH and lower total acidity than those from owner shops. The L, a and b values of the regular coffees were higher than those of the espresso coffees. With the exception of the a value of regular coffees, all the color values of the coffees from owner shops were higher than those from the chain shops. The intensity of the brownness, soluble solid contents and total phenolic contents of the espresso coffees were about 7-8, 8-9 and 4 times higher, respectively, than those of regular coffees. In addition, the free radical scavenging capacities and antioxidant activities of the espresso coffees, using a chemiluminescence assay, were higher than those of regular coffees. Espresso coffees from chain shops, especially, had higher activities of free radical scavenging than those from owner shops. In conclusion, the characterics of coffees from chain shops were significantly different from those from owner coffee shops.

The purpose of this study is to investigate the fundamental properties of concrete mixed with crushed oyster shells(OS) as coarse or fine aggregates. For this purpose, five reference mixes with W/C ratios of 0.4∼0.6 at intervals of 0.05 were considered. The replacement proportion of OS was varied with ratios of 0, 10, 30, 50 and 100% by volume of fine or coarse aggregate in the reference mixes. OS was washed and crushed for using as aggregates. New chemical reaction between crushed OS aggregate and and cement paste was tested through XRD and SEM analysis. The compressive and flexural strength properties were considered. Strength tests were carried out at the ages of 1, 3, 7, 14, and 28 days. The variation of workanility, air content and density, drying shrinkage of the specimens with different proportions of OS were also studied. Finally, the hollow concrete block using OS as a substitute material for fine aggregate was made for testing the application of OS. Experimental results showed that any new chemical reaction did not occur due to mixing crushed OS in ordinary concrete. The workability and strengths decreased with increase in proportion of OS. The same trend was observed in density and unit weight, but air content increased due to the inherent shape and texture of OS, which showed a possibility to produce light weight concrete with low strength by using OS as coarse aggregates for concrete. Tests on hollow concrete block showed that the compressive strength and absorption ratio were satisfied with quality requirements when the fine aggregate was substituted with OS up to 50% in volume.

The purpose of this study was to investigate the instrumental and sensory characteristics of coffee-sulgi(rice cake) with different ratios of the ingredients; coffee(30㎖, 40㎖ and 50㎖ of espresso and instant coffee) and sugar(50g and 75g). A commercial scheme for coffee-sulgi was also investigated. The optimal mixing ratios of coffee-sulgi with added espresso were rice flour 500g, salt 5g, espresso 40㎖ and sugar 75g. Those of coffee-sulgi with added instant coffee were the same. As the sensory intensities of coffee aroma, coffee taste, sweetness, moistness, elasticity, color acceptance for coffee-sulgi and overall acceptance for quality were enhanced, the overall preference for coffee-sulgi was increased. In addition, overall preference was positively correlated with adhesiveness and a-value of instrumental characteristics, but negatively correlated with cohesiveness and L-value. In coffee-sulgi with added espresso, intensities of coffee aroma, browniness, coffee taste, color acceptance for coffee-sulgi, overall acceptance for quality and overall preference were higher than those of coffee-sulgi with added instant coffee. In this point, gourmet coffee-sulgi with added espresso and universal coffee-sulgi with added instant coffee could be differentiated in the coffee-sulgi markets. In conclusion, this study of coffee-sulgi and the differential scheme for the market will be useful to expand rice processing, enhance the intake of rice cakes and provide a reference for commercialization of rice cakes.

In order to investigate the availability of insect resources for agrobiotechnological or medical purposes, we examined antioxidant (DPPH and FRAP assay) and cell viability by oxidant stress and NO inhibition assay by treatment of the extracts of Statilia maculata Thunberg, Tenodera angustipennis Saussure and Tenodera aridifolia Stoll. We found that Tenodera angustipennis Saussure and Tenodera aridifolia Stoll extract (DW, etanol, methanol) had high levels of anti-oxidant activity, whereas Tenodera aridifolia Stoll extract showed increased cell viability by hydrogen peroxide and inhibition of NO production. These findings suggest that Statilia maculata Thunberg, Tenodera angustipennis Saussure and Tenodera aridifolia Stoll, extract have potentials to be developed for agrobiotechnology or medicinal use, indicating that mechanistic study including inhibition against molecular inflammation will show a possibility for the development of useful insect resources.

In recent years, gonorrhea has been pandemic and remains one of the most common STDs in the world, especially in developing countries. For the detection of a more effective therapeutic regimen and assessing the prevalence of Penicillinase Producing Neisseria gonorrhoeae(PPNG), we have been trying to study the patients who have visited the Venereal Disease Clinic of Choong-Ku Public Health Center in Seoul since 1980 by menas of the chromogenic cephalosporin method. In 1998, 93 strians of N. genorrhoeae were isolated, among which 60(64.5%) were PPNG. The prevalence of PPNG in Seoul, which had been decreased to 39% in 1996 after a peak of 74.3% in 1993, is increased to 64.5% in 1998.

Background: We aimed to explore the recent 11 years (2002-2012) incidence trends of chronic hepatitis B (CHB), chronic hepatitis C (CHC), liver cirrhosis (LC) and primary liver cancer (PLC, subcategories: hepatocellular carcinoma, intrahepatic bile duct and unspecifi ed liver tumors) and mortality trend of PLC in Korea.Methods: We analyzed trends of incidence rates (the number of patients divided by total population covered by health insurance service) per 100,000 by age and sex for the recent 11 years in CHB, CHC, LC and PLC from the data of National Health Insurance Service (NHIS). We also analyzed trend of mortality rates caused by PLC per 100,000 by sex for the recent 11 years from the data of Korean Statistical Information Service (KOSIS). Results: From 2002 through 2012, CHB incidence rates per 100,000 decreased among indivisuals aged 20-29 years but increased among indivisuals aged 30+ years: CHC incidence rates per 100,000 decreased among 20-39 year-old men but increased in the other groups: LC incidence rates per 100,000 decreased among men aged 20-69 years and women aged 20-59 years but increased among men aged 70+ years and women aged 60+ years: PLC incidence rates per 100,000 decreased among men aged 20-49 years and women aged 20-59 years but increased among men aged 50+ years and women aged 60+ years (all trends showed signifi cant changes). The overall mortalityof PLC decreased in both sexes (the maximum change of a year was in 2011) but did not show signifi cant changes. Conclusions: The incidence rates of CHB, CHC, LC and PLC among the younger decreased and the mortality rates of PLC didn`t decreased signifi cantly. This will help to predict the future prospect of liver diseases in Korea.
