  • Annual changes of nutrient intakes of Koreans and Japanese were compared on the basis of the data from the National Nutrition Survey which has been carried out annually in Korea (1969-1988) and in Japan (1950-1988) for the guide of the future food and nutrition policy. Intakes of all nutrients except carbohydrate and protein by Koreans were lower than those of Japanese in 1988. The intake of lipid by Koreans was less than one half of the intake by Japanese. The intake of protein has been increased to 79.2g in Korea and 91.6g in Japan, of which 49% and 52.6% were provided by the animal sources in Korea and Japan, respectively, in 1988. In terms of consumption of the energy nutrients, the percentage of carbohydrate has been decreased, while those of protein and lipid have been increased in both countries. In 1988, the ratios of energy intakes by carbohydrate, protein and lipid were 67 : 19 : 14 in Korea and 59 : 15 : 26 in Japan. Considering the desired ratio, 65 : 15 : 20, the intake of carbohydrate seems to be still high and that of lipid still low for Koreans. The food supply has been increased in both countries and the supply of animal food, oil and fat were greater in Japan than in Korea.

  • Electronic Commerce (EC) is a relatively new and has been attracting a considerable amount of attention. Even though it is still in an introductory stage, growth rates are impressively high and its economic importance will continue to grow. Electronic Commerce is born to be global because its connectivity using the Internet is universal. As Electronic Commerce accelerates the globalization, it will also increase both the interdependence of national economies in different countries and the need for international cooperation and coordination. Electronic Commerce is really a global challenge that requires global solutions. For this reason, Electronic Commerce becomes an important agenda in major international cooperative organizations including APEC, OECD, and G7 (G8). However, current international discussions on Global Electronic Commerce are initiated mostly by the United States and European Union (EU). The objective of this paper is to raise awareness creation activities in which the international cooperation is needed for promoting the global electronic marketplace in Asia. For this purpose, this paper reviews the approaches of U.S. and European countries (or European Union), and suggests an development framework on the basis of the reviews. The framework is used to analyze current issues around Electronic Commerce, and identify some fields which require coherent work among researchers in different countries.

  • Since 2015, countries in the Sahel region have implemented large-scale seasonal malaria chemoprevention (SMC). However, the mass use of sulfadoxine-pyrimethamine (SP) plus amodiaquine impacts the genetic diversity of malaria parasites and their sensitivity to antimalarials. This study aimed to describe and compare the genetic diversity and SP resistance of Plasmodium falciparum strains in Mali and Niger. We collected 400 blood samples in Mali and Niger from children aged 3-59 months suspected of malaria. Of them, 201 tested positive (Niger, 111, 55.2%; Mali, 90, 44.8%). Polymorphism of merozoite surface protein 1 (msp1) genetic marker showed 201 allotypes. The frequency of the RO33 allotype was significantly higher in Niger (63.6%) than in Mali (39.3%). There was no significant difference in the frequency of the K1 and MAD20 allotypes between the 2 countries. The multiplicity of infection was 2 allotypes per patient in Mali and one allotype per patient in Niger. The prevalence of strains with the triple mutants Pfdhfr51I/Pfdhfr59R/Pfdhps436A/F/H and Pfdhfr51I/Pfdhfr59R/Pfdhps437G was 18.1% and 30.2%, respectively, and 7.7% carried the quadruple mutant Pfdhfr51I/Pfdhfr59R/Pfdhps436A/F/H/Pfdhps437G. Despite the significant genetic diversity of parasite populations, the level of SP resistance was comparable between Mali and Niger. The frequency of mutations conferring resistance to SP still allows its effective use in intermittent preventive treatment in pregnant women and in SMC.

  • The present study was conducted to assess the dietary exposure to mercury and the associated risks for Koreans resulting from their food intake. The probabilistic approach in the Monte Carlo simulation was used to estimate dietary exposures. Based on several reports regarding heavy metals published by KFDA in the 2000s, 178 types of representative foods were selected and data were collected on the occurrence of mercury. The contents of mercury in foods ranged: agricultural products 0.1 (fruits)-45.4 ${\mu}g/kg$ (mushrooms), 3.7 ${\mu}g/kg$ (meat), and 9.3 (Echinodermata, chordata)-194.9 ${\mu}g/kg$ (fish). Others categories investigated were alcoholic beverages (0.7 ${\mu}g/kg$) and processed food (4.4 ${\mu}g/kg$). The mean and 95th percentile for exposure to dietary mercury were 4.29 and 12.48 ${\mu}g/day$, corresponding to 13.6% and 39.7% of PTWI (Provisional Tolerable Weekly Intake), respectively. Therefore, overall level of mercury exposure for Koreans through food intake is below levels recommended by JECFA, indicating the least possibility of risk, and is less than or similar to levels reported in other countries.

  • Available data on the recent global financial crisis (GFC) show that it lasted between the second quarter (Q2) of 2007 and the fourth quarter (Q4) of 2009. Australia is one of the first economies to fully recover from this crisis. This study explorles the role played by the Australian construction industry in stimulating economic growth during the recession. In order to investigate the macro-variability trend during the financial crisis, data were collected and analysed relating to the quarterly GDP of Australia and selected countries between Q1 2000 and Q4 2009. Specifically, changes in the construction industry's GDP were compared with aggregate GDP changes in Australian economy and similar indices in the 'Group of 7' (G7) countries and Organisation for Economic Co-operation and Development (OECD) countries. Moreover, specific attention was focused on Germany, France, Japan, United States of America (USA) and United Kingdom (UK). Graphical and Pearson's correlation methods were used to analyse the relationships between changes in construction GDP and Australia's overall economic growth during the recession. In addition, an attempt was made to develop a regression model for predicting economic growth during the recent recession using changes in gross fixed capital formation (GFCF), changes in construction GDP and the impact of these changes on national economy. Analysis shows a slight contraction in construction activities during the crisis; however construction triggered significant growth in the economy during the crisis period and afterwards. This appears to be the major difference between Australia and other major economies that have experienced a longer recession.

  • This study was carried out to find a new corn cultivar with multiple tillers that is suitable for forage. Materials were developed at the Corn Breeding Laboratory of Chungnam National University. A total of 3,650 accessions were collected domestically and from other countries, including China. Among them, 16 CNU inbreds, tillering and non-tillering, were compared to each other in terms of stem heigh, number of tillers, fresh weight, and dry weight per plant. Of these surveyed traits, the stem heigh at tasseling stage was 140~190 cm and number of tillers per plant ranged from two to four. Fresh weight and dry weight of these lines were higher in the tillered than in the non-tillered sample.

  • The air pollutant emission from the railroad diesel locomotive is still a significant environmental concern in many countries including Korea and Unites States. The emission characteristics of the railroad diesel locomotive were extensively studied in this study. Particulate matter (PM) and nitrogen oxides ($NO_x$) emitted from a large locomotive engine (2-cycle, 16-cylinder, and 3,000-horsepower) under various engine-rating conditions was analyzed with a scanning mobility particle sizer and a gas stack sampler by using a dilution tunnel. We could gain the emission values of 2.1 g/horsepower-hour for PM and 42.7 g/horsepower-hour for $NO_x$. We proposed the emission reduction goal of the railroad diesel locomotive for Korea in comparison with the regulation of United States.

  • Eight morel mushroom species were collected from Korea and other countries. The culture characteristics, genetic relationships, and beta-glucan content of the strains were analyzed. The mycelia of Morchella species exhibited optimal growth when cultured in dark at 25 ℃ in media with pH 7. The mycelia had a distinctive mycelial scent and characteristically changed color, being white initially, and then turning dark yellow to dark brown as it grew. The mycelia were classified into five types based on morphology. The isolates were identified as Morchella conica, two M. sextelata, M. importuna, M. esculenta, and three M. crassipes, based on ITS-rDNA sequences. PCR polymorphisms were variably produced within Morchella spp. using Universal Fungal Fingerprinting Primers (UFPF) and classified into four groups at the intra and inter species level. The strains, KMCC04971 and KMCC04407, showed the same banding pattern as M. conica and M. sextelata, respectively; however, these results were different from those of ITS analysis. Glucan content analysis by strain showed that the KMCC 04973 strain of M. importuna had the highest alpha- and beta-glucan content, at 16.4 g and 33.1 g per 100 g, respectively.

  • Coriander(Coriandrum sativum L.), which has a unique flavor and antioxidant and anti-cancer effects, is a natural functional spice most preferred by Chinese, and its nutritive superiority is recognized and its consumption is increasing even in Western countries. This study attempts to increase use and consumption of Gochujang in the Chinese market by adding coriander to Gochujang. For this purpose, coriander powder and extract were added to Gochujang. Conclusions drawn from this study are as follows. CP7(7 g of coriander powder, 93 g of hot pepper paste) showed the highest score in color(4.04), coriander smell(3.72), coriander taste(3.92), and softness(4.36) while CJ4(10 g of coriander juice, 90 g of hot pepper paste) showed the highest score in gloss(3.42), coriander smell(3.04), and coriander taste(4.29), This reveals that, with increase in the addition of coriander extract, coriander smell and taste grow stronger and Gochujang smell and taste grow weaker.

  • The building section is providing immediate causes for global climate change problems since it takes about 50% of carbon emission, 20~50% of waste discharge, 33% of energy consumption, 40% of resource use, and 17% of water consumption. So, many countries over the world have developed and implemented green building certification systems to assess sustainable performances of buildings since the early 1990s. In korea, the green building certification system to induce the diffusion of sustainable buildings was first introduced in 2002 and developed as an improved version of the G-SEED(Green Standard for Energy and Environmental Design) system in 2013 after major revisions of related legislations. This research conducts a survey targeting residents on an apartment building that was certified as green building and examines the importance of assessment criteria on apartment buildings to certify green buildings using the Analytic Hierarchy Process(AHP) method. And it proposes a new direction on certification assessment standards from the resident's prospective. As a result, assessment criteria such as indoor environment, ecological environment, energy & environment pollution, and maintenance management among 7 main ones turned out important on assessing the G-SEED system for apartment buildings, while criteria such as material & resource, water circulation management, and land use & transportation did relatively unimportant.
