Purpose - After the transition, the development of defense industry in Eastern Europe has been regressed. Recently, they have internationally recognized that new products have been exported and contributed to the Innovation-Based Manufacturing of national economy such as unmanned reconnaissance aircraft, water purification technology, and mobile chemical laboratory, etc. The military forces in Eastern Europe are re-armed by the localization of self-produced munitions in their own defense industry, and then emphasize fostering their own defense industry. Thus, if they make a collaboration with other nations as a industrial cluster, it will gain a competitive edge on the defense industry. Research design, data, and methodology - The study was designed with the data of each national defense department. The research of the subject was reviewed before and after the transition. Thousands of workers have worked in defense industries before the transition, however, the defense industry and experts left after the transition. The Hungarian defense spending on GDP also dropped sharply from 1.72% in 2000 to 0.85% in 2013. But, due to the crisis in Ukraine and the crisis of Syrian refugees, the Viségrad Group (V4) member countries have also increased their interest in a defense and industries as well as the confidence in the EU and NATO. Results - On the whole, the joint of military training and purchase of defense materials were found in order to form the EU cooperative combat troops in CEE. There are the implementation of a joint manual plan for strengthening V4 security policy and the joint military exercises for V4 every year, and the others are electronic warfare and innovation of V4 national forces. Through such a performance analysis methodology, we found that the defense industry is developed through the national cluster cooperation among CEEs and spreading global distribution. Conclusions - Eastern Europe and Balkan countries have been looking forward to cooperating with the non-EU countries such as Korea and other defense industries. There are a lot of potential development into a new civilian cooperation defense industry for global-distribution. Thus, Korea should develop electronic commercial applications, not just as a weapon exporting region.

The main objective of the present study is to elucidate a correlation between ship resistances from computational fluid dynamics (CFD) and brake horse powers (BHP) from towing tank in container carriers. The tests were conducted for a range of combinations of trim conditions and speeds. To achieve this goal, 295 cases of numerical simulation have been performed using Star-CCM+ which had been statistically verified to predict ship resistances (Lee & Lee, 2014). Based on the normal distribution of resistance errors in all cases of the 4 container carriers, the confidence interval of numerical error was estimated as [-2.33%,+2.42%] with 95% confidence. The correlation coefficients between the ship resistances of CFD and the brake horse powers of the experiments were higher than 0.93. As a result, the numerical calculation of ship resistances is able to be utilized in order to provide a quick guidance in selection of the optimum loading condition.

Vietnam is conducting an export-led growth model and labour-intensive industries contributing majorly to the total export value. In the context of Industry 4.0, the labour-based industries are significantly affected; hence, enhancing productivity is the key measure to maintain these industries. The garment industry contributes significantly to the total export value of Vietnam. Based on meta-frontier framework, the approach of data envelopment analysis is used to measure technical efficiency of Vietnamese garment firms and the global Malmquist TFP index is utilised to identify productivity change and its components including efficiency, technology and technical gaps between different groups of firms. The data of Vietnamese garment firms from 2013 to 2018 collected from the Vietnam General Statistic Office is used in this study. The results show that: (i) The total factor productivity of Vietnamese garment firms growth, technical progress is the main contributor; (ii) The private garment sector is the leading group; (iii) There is a large technological gap among Vietnamese garment sectors. The private and FDI garment firms have experienced a growth in all components of total factor productivity change. Meanwhile, technological progress change is the main reason to constrain the productivity growth of state-owned garment firms.

To determine the sodium content of meals provided by foodservice institution, 540 different menus were collected by their serving portion and categorized into nine food groups and three different foodservice types (office, industry, school). Each were evaluated by each sodium evaluation method. All nine categories of food type showed higher content of sodium than listed in the 'nutrition assessment program (Can-Pro 4.0)', when assessed with a salimeter. From the 9 food types, 6 types, excluding 'Korean pancakes', 'Kimchi/pickled food' and 'a la carte', showed significantly higher sodium content on the salimeter than shown in the 'nutrition assessment program (Can-Pro 4.0)' (p<0.001). Also in assessing sodium content per serving, 'soup and stews' and 'a la carte' menus had significantly higher sodium content than other food types (p<0.001). The results compared by foodservice types showed dishes served in 'Industries' had significantly higher daily sodium content than those served in 'offices' and 'schools'.

Objectives: The aim of this study was to investigate the distribution patterns and exposure concentrations of biological hazards in waste handling industries. Methods: We selected 3 recyclable waste sorting plants(RWS), 2 food recycling plants(FR), 1 landfill area(LA) and 1 waste incineration plant(WI). Total airborne bacteria and fungi were measured with single stage impactor and gelatin filters. Endotoxin and glucan were measured with polycarbonate filters in total and respirable dust. Results: The geometric mean of airborne bacterial concentration was the highest in FR($3,273CFU/m^3$), followed by LA, RWS, and WI as 1,334, 934, and $860CFU/m^3$. The fungal concentrations were 6,031, 5,052, 3,307, and $713CFU/m^3$ in RWS, WI, FR, and LA, respectively. By process, WI pit showed the highest concentrations of bacteria, fungi, and endotoxin, followed by inside of bulldozer in LA. The indoor to outdoor ratios of bacteria, fungi, endotoxin and glucan were 2.3, 4.0, 2.3, and 5.0 in RWS, 29.5, 4.9, 7.6, and 5.0 in FR, 5.3, 8.7, 26.8, and 9.5 in WI, respectively. Conclusions: We found that biological hazards, specifically bacteria in FR, fungi in RWS and endotoxin in WI pit and bulldozer at LA, should be controlled to prevent worker's respiratory diseases.

This study is assessed the urinary hippuric acid (HA) concentration in toluene-exposed workers. Toluene is widely used in the coating, printing, painting and petroleum industries. We analyzed the hippuric acid level of toluene-exposed workers (males: 198, females: 63) from 2008 to 2010 and examined the relationship between hippuric acid and the characteristics of their work. The measurements of the urinary hippuric acid were confirmed by high-performance liquid chromatography. Among the subjects, males had on average more work experience than females (males: 9.17 years, females: 4.45 years), but females showed a higher hippuric acid concentration levels than males (males: 0.26 g/L, females: 0.75 g/L). The mean of the HA concentration according to the age group was 0.19 g/L in 30's, 0.30 g/L in 40's, 0.54 g/L in 50's, 1.36 g/L in 60's. Those in their 60's had the highest concentration. The mean of HA concentration according to the type of work was 0.70 g/L for the coating, 0.52 g/L for the painting, and 0.16 g/L for the printing industries, revealing that the workers in the coating industry had the highest concentration. By the highest order, the mean of HA concentration by working period was as follows; less than 5 years, ${\leq}5\;years{\sim}<10\;years$. The factors that influence the HA concentration are not only how long one is exposed to toluene but also the type of work, worker's age, and their gender.
