The results of gas chromatography–mass spectrometry (GC–MS) demonstrate that the volatiles captured by diamond grown by chemical vapour deposition (CVD) technology contain hydrocarbons and their derivatives (72.2 rel. %). We have identified aliphatic (paraffins and olefins), cyclic (naphthenes and arenes) and oxygenated (alcohols, aldehydes, ketones and carboxylic acids) hydrocarbons, as well as nitrogenated and sulfonated compounds. Water, negligible amounts of CO2 and Ar were also detected among the volatile components.

The objective of this study was to analyze proximate composition, dietary fiber, mineral content, fatty acid composition in Cheonggak (Codium fragile) in order to encourage the consumption of Cheonggak. The proximate composition of Cheonggak was found to be 5.51% moisture, 24.09% crude ash, 15.79% crude protein, 2.47% crude lipid and 45.31% dietary fiber. The major mineral content of Cheonggak was Na 8,950 mg/100 g, Mg 1,252 mg/100 g, Ca 807 mg/100 g, K 457 mg/100 g, and trace mineral content was Fe 26 mg/100 g, Mn 8 mg/100 g, Zn 0.4 mg/100 g. Palmitic acid 36.86% and α-linolenic acid 20.14% were the most contained fatty acids in Cheonggak. The ratio of saturated fatty acids to unsaturated fatty acids was 85.49% while ω-6 fatty acids to ω-3 fatty acids were 59.10%. Based on the proximate composition, dietary fiber, mineral content, and fatty acid composition, Cheonggak was judged to be a major source of dietary fiber and Mg and Ca, and it was deemed to be helpful in promoting health, including the prevention of hyperlipidemia. Cheonggak contained valuable nutrients similar to seaweed, which is produced and consumed the most in Korea. Thus, it is necessary to include Cheonggak in the food items.

In this paper, we investigate to determine quality characteristics, fatty acid composition and cytotoxic effect of extracts and fractions from whole Lycopus lucidus Turcz. roots. Additionally, we evaluated cytotoxic activity against the growth of human fibrosarcoma cells (HT-1080) and human gastric adenocarcinoma (AGS), human colon cancer cell (HT-29) lines using a 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay. Acetone+methylene chloride (A+M) and methanol (MeOH) extracts from L. lucidus Turcz. were obtained through solvent extraction. Then we further fractionated both extracts with n-hexane, 85% aq. MeOH, n-butanol (n-BuOH) and water. In fatty acid composition, L. lucidus Turcz. contained 33.2% of 18:1n-9 and 1.81% of 18:3n-3, respectively. The incorporation of treatment with A+M and MeOH extracts and n-hexane, 85% aq. MeOH, n-butanol (n-BuOH) and water fractions dose-dependently increased cytotoxicity against the growth of HT-1080 and AGS, HT-29 cancer cells (p<0.05). The A+M extract had a higher inhibitory effect on the growth of all cancer cells in comparison to MeOH extract. Among the fractions, the 85% aq. MeOH and n-hexane fractions showed a higher inhibitory effect after proliferating the three cancer cells. These results suggest that the 85% aq. MeOH and n-hexane fractions have a potential to inhibit the growth of human cancer cell lines.

PURPOSES : It is necessary to clarify the rheological properties of cement paste as a basic research in the development of mechanistic concrete mix design. The rheological properties of cement paste with different binder types, mix propositions, and with/without high range water reducers have been analyzed. METHODS: In this study, ordinary Portland cement, fly-ash, blast furnace slag, silica fume, and limestone powder were used as binders. The range of water-binder ratio was 0.3-0.5, and a total of 30 different mixes have been tested. The slump flow test, V-funnel test, and Dynamic Shear Rheometer (DSR) test were performed to analyze the rheological properties of cement paste. RESULTS : As a result of the slump flow test, it was found that the composition ratio of the binder contents greatly affected the paste flow when the high range water reducers were added. The results of V-funnel test showed that when the water-binder ratio was decreased without high range water reducers, the binder composition ratio had a large effect on the passing time of the V-funnel tester, but with high range water reducers the impact of the binder composition ratio was decreased. The slump flow and V-funnel have a certain relationship with the rheological factors (yield stress and plastic viscosity), but the correlation was not significant. Finally, we proposed the M-value considering the density and specific surface area of the binder. The correlation between rheological factors and M-value were better demonstrated than experimental values, but there is still a limit to predict the rheological factor in general mix design. CONCLUSIONS: In this study, the rheological properties of cement paste were analyzed. The binder type, composition ratio of binder, and with/without high range water reducers have combined to provide the complex effects on the rheological properties of cement paste. The correlation between the proposed M-value and rheological factor was found to be better than experimental results, but needs to be improved in the future.

Along with toothbrushes, toothpaste has been used for a long time to improve the personal oral hygiene. Toothpaste was firstly introduced to Korea through as a form of powder by the Japanese company Lion Corporation in 1889 and in 1954, the LakHee Chemistry company released Korea’ s first ever tube type cream toothpaste called lucky toothpaste, and afterwards we got to where we are today in terms of toothpaste. As a variety of products are released and customer choices become more diverse, there needs to be a development of toothpaste that can fulfill customers’ needs and requests. Therefore, this study analyzes toothpastes and related patents submitted to the Patent Office from 1962 to June 2015, thereby examining the changes in toothpaste development trends up to the present day. This study was searched using the keyword ‘toothpaste’ in the patent, utility model search engine at Kipris(www.kipris.or.kr), a patent search site, and categorized a total of 2,465 patents, which excluded those rejected by the Patent Office and those unrelated to toothpaste, using titles, full texts of publications and announcements. Research results showed that in the past, from 1960 to 1989, patents related to toothpaste containers took up the highest ratio of 35%. However, after 1990, patents pertaining to toothpaste composites and functionality made up the highest percentage of 54%, and from 2010 to 2015, it occupied 72% of the whole; therefore, we analyzed in detail the patents related to composites and functionality. Taking a look at the objectives and effects of patents having to do with composites and functionality, we found out that from 1964 to June 2015, patents related to Base, a basic component of toothpaste, and those having to do with periodontal disease took up the highest percentages of 25% each, and from 2010~2015 in particular, patents concerning periodontal diseases were submitted 3% more than those about Base. Composites aiming to prevent and treat periodontal diseases can be divided into four different categories, based on components; among those, there were a total of 171 (57%) patents related to living organism and herbal medicine extracts, 107 (36%) patents using compounds, 16 (5%) patents using bamboo salt as well as salt, and 5 (2%) patents using mineral components such as gold, silver. Looking at these investigation results, it can be thought that with the increasing development of toothpaste related to periodontal diseases, there’ s a great amount of interest about toothpaste of effective periodontal disease prevention and treatment purposes. Along with this, we thought that research about how effective periodontal disease toothpastes actually are is also necessary.
