Salvia plebeia R. Br. (Labiatae), distributed in many countries such as Korea, China, India, Iran, and Australia, is used as a folk remedy for a variety of inflammatory diseases including hepatitis, cough, diarrhea, gonorrhea, menorrhagia, tumors, and hemorrhoids. This study focused on determining the involvement of anti-inflammatory heme oxygenase-1 (HO-1) in the inhibitory activity of an extract of Salvia plebeia R. Br. leaves (SPL) on nitric oxide (NO) production and inducible nitric oxide synthase (iNOS) expression in lipopolysaccharide (LPS)-stimulated RAW264.7 macrophages. SPL extract at the highest concentration (500 ${\mu}g/mL$) significantly inhibited NO production by approximately 85% and suppressed iNOS protein expression by approximately 90% compared to LPS-stimulated cells. The SPL extract induced the expression of HO-1 in a dose-dependent manner, and blocking HO-1 activity abolished the inhibitory effects of the SPL extract on NO production. These results suggest that an SPL extract has potent anti-inflammatory activity through HO-1 induction in RAW264.7 macrophages.

Nepal is a landlocked mountainous country in South Asia, located between China to the north and India to the south, east, and west. As such, wastewater management has become one of the most significant problems in urban area of Nepal. In Nepal, the centralized wastewater treatment systems were dysfunctional due to high cost of operation, discontinuous power supply, lack of proper maintenance and proper technical workforce to address the issues. As such, constructed wetlands (CW) were applied to treat various secondary wastewater as alternative to wastewater treatment facilities. Generally, efficiency and sustainability of CW technology depends on proper operation and maintenance and active community involvement. This study summarizes information about 26 CW in Nepal. Specifically, factors including data banking, removal efficiency, quality of discharged water, compliance to water quality standard of Nepal and operation and maintenance were investigated. Considering removal efficiency per pollutant, Ka-1 achieved the greatest reduction for most pollutant followed by B-1, L-3, Ka-5 and K-1. Nepal has practiced CW technology for more than 2 decades but currently, development of technology was interrupted by the inefficient performance of existing facilities. Public awareness about the technology, natural disaster, unavailability of specified substrate materials, lack of fund for further research and experiments has hindered the expansion of technology. In spite of these concerns, CW was still proven as an alternative solution to the present wastewater problems in urban areas of Nepal.

This study is written to bring the proposal forward for the direction of south korean naval force. The political situation and the circumstance of the world, especially in the area of Pacific Ocean, are changing very rapidly. North Korea has been always the conventional existing intimidator for South Korea since the 6·25-War. Additionally, the strengthening movements of the national defense, which is easily noticed from China and Russia, is also an other part of intimidating countries against South Korea. Those three mentioned countries are continually developing the asymmetrical warfare systems, for example a strategic nuclear weapon. Since the Obama Administration, the Asia-Pacific Rebalancing-Strategy has been changed as an East Asian foreign policy. Nowadays, Trump Administration renamed the 'United States Pacific-Command' to 'United States Indo-Pacific Command'. The purpose of this is not only letting India to participate in american alliance, but also reducing an economic burden, which is often mentioned in USA. West Germany was located in the very similar geopolitical position during the Cold War just like South Korea these days. And that's why the strategy of West German Navy is worthy of notice for south korean naval force to decide its suitable strategy. Most of all, the two most important things to refer to this study are the plan to expand naval air force and the realistic political stand for us to take it. In conclusion, I laid an emphasis on maintenance of 'green-water-navy'. instead of selecting the strategy as a 'blue-water-navy'. The reason I would like to say, is that south korean navy is not available to hold the unnecessary war potential, just like Aircraft-Carrier. However, this is not meaning to let the expansion of naval force carelessly. We must search the best solution in order to maintain the firm peace within the situation. To fulfill this concept, it is mostly very important to maintain the stream of laying down a keel of destroyers, submarines and air-defense-missile, as well as the hight-tech software system, taking a survey of 4th industrial revolution. Research and development for the best solution of future aircraft by south korean navy is likewise necessary. Besides, we must also set the international diplomatic flexibly. As well as maintaining the relationship with US Forces, it is also very important to improve the relationship with other potential allied nation.

In order to obtain the basal data far quality and sanitary stability of sesame oil extracted from imported sesame flours oil of whole sesame and flour sesame were investigated the proximate composition, chemical properties, fatty acid composition, sesamol, sesamolin, sesamin contents and oxidation induction period by AOM test. Moisture contents of sesame flours were less remarkably than whole sesame. There were no differences in proteins. Acid value and saponiflcation value were higher sesame flour oil than whole sesame oil. iodine value of sesame flour oil were lower than whole sesame oils. In fatty acid composition of sesame oil, contents of linolenic acid and linoleic acid were 222.44 ∼144.14 and 2713.00 ∼ 1776.46 mg/mL, respectively. And the contents of linoleic acid and γ-linoleic acid were lower sesame flour oil than whole sesame oil. The sesamol contents of sesame oil were higher whole sesame oil than sesame flour oil, sesamol content of India whole sesame oil was highest of them. The sesaminl sesamolin contents of Korean whole sesame oil were the Highest Oxidation induction periods of sesame oil by AOM were 6.76 and 13.35 In on north Korea and Chinese sesame flour oil, respectively. Therefore, it appears that oxidative stability was lower in north Korea and China sesame flour oil than in whole sesame oil group.

The depletion of conventional oil reserves and the increasing energy need in developing countries such as China and India result in exceeding oil demand over supply. As a solution of the problem, the efficient utilization of heavy oil has been receiving more and more interest. In order to utilize heavy oil, upgrading processes are required. Among the upgrading processes, thermal decomposition is thought to be relatively simple and economical. In this study, to understand basic characteristics of thermal decomposition of heavy oil, we conducted pyrolysis experiments of deasphalted oil (DAO) produced by a solvent deasphalting process. DAO is a mixture of many components and consists mainly of materials of carbon number 20~40. For the comparison with results of DAO pyrolysis, additional pyrolysis experiments with single materials of carbon number 30 ($C_{30}H_{62}$, $C_{30}H_{58}O_4S$, $C_{30}H_{63}O_3P$) were conducted. Pyrolysis experiments were carried out non-isothermally with variation of heating rate (10, 50, $100^{\circ}C$/min) in a thermogravimetric analyzer. Average pyrolysis activation energy determined by using Arrhenius method, Ingraham and Marrier method, and Coats and Redfern method was 72~99 kJ/mol. In the activation energy calculated by Ozawa-Flynn-Wall method, DAO had wider variation than other single materials.

In order to control and manage oil-tanker scrapped materials and wastes properly, the actual conditions and global trends of the treatment and the management of ship scrapped wastes were surveyed and some amendments to marine pollution prevention law of Korea were proposed. Global annual volume of scrapped ships was estimated to be about 22 million DWT and most of them were scrapped in 4 major ship scrap countries such as Bangladesh, China. India and Pakistan and in minor ship scrap countries such as Turkey, the Philippines, Indonesia and Vietnam. The industry of ship scrap has been mainly developed in developing countries or undeveloped countries rather than in advanced countries. Most of scrapped ships were found to be small or medium size below 1,000 GRT In Jellanam-Do and Jeju-Do of Korea. Most of ship scrap enterprise and all enterprises of collection, transfer, treatment and disposal for ship scrapped materials and wastes were shown to be small sized in Korea. The regulations and/or rules which shall prohibit or limit trans-boundary movement of overage oil-tankers for scrap from Korea to developing or undeveloped countries, and vice versa should be Included in marine pollution prevention law of Korea. the criteria of manpower and facilities for enterprise of ship scrap, and for enterprises of collection, transfer, treatment and disposal of ship scrapped materials and wastes should be stipulated in marine pollution prevention law of Korea. It is desirable to introduce the system or concept of recycle or reuse of ship scrapped materials and wastes on producer's responsibility into marine pollution prevention law of Korea.

Skin properties are influenced by a variety of internal or external factors. This study was conducted to investigate and compare the skin characteristics in Asian women. We evaluated values of skin physical parameters, and then assessed the correlations among the parameters, and regional differences in 1,500 Asian subjects in seven countries (Malaysia, Indonesia, Vietnam, Thailand, India, China, and South Korea). The values of transepidermal water loss (TEWL), pH, skin hydration, sebum content, skin sensitivity, elasticity, crow's feet wrinkles, and skin brightness were measured. New Delhi's women were observed to have a lower level of hydration in stratum corneum, sebum content, stinging scores, and darker skin color than others. Furthermore, their skin surface pH on all sites is the highest among seven countries. Vietnamese had the lowest pH values in skin surface. Korean and Chinese had generally higher elasticity and fewer wrinkles. Both the skin hydration and TEWL had positive correlations with the stinging test, and there was a negative correlation between wrinkles and stinging test. These results represent that there was no clear trend related to the area or region. Skin physical parameters should be studied along with understanding of regional differences and various factors (skin care habits, lifestyle and personal sensitivity).

BACKGROUND: Inorganic component is made up largely of salt, because the criteria are difficult to split into domestic and imported ingredients, organic examined the fatty acid composition is to see a possible use as a marker using gas chromatography-mass spectrometry (GC-MS). The 14 domestic samples and 8 imported samples were collected from China, India and other countries were investigated on item of 37 fatty acids. METHODS AND RESULTS: The major components were six species, myristic acid ($C_{14:0}$), palmitic acid ($C_{16:0}$), palmitoleic acid ($C_{16:1}$), stearic acid ($C_{18:0}$), oleic acid ($C_{18:2,n9}$), linoleic acid ($C_{18:2,n6}$) among detected twenty fatty acids including 9 unknowns. The content of palmitic acid were highest as 25.2 to 50.8% of total fatty acids contents. Domestic has seen the most amount of salt in the Taepyeong salts $250.8{\mu}g$/100g, imports $135.2{\mu}g$/100g salt in Chinese Weifang salts showed the lowest content. CONCLUSION(s): The total fatty acid content has seen the most amount of salt in 352.3 ug/100g Christmas island salts showed the lowest content of $164.0{\mu}g$/100g, as a result it is difficult to distinguish the domestic salts and imported by the composition of fatty acid.
