This study attempts to investigate the effects of different types of debts on economic growth in Bangladesh using time series data spanning from 2000 to 2015. In this study, the RDL model has been applied to determine the long run relationship among the selected variables. The result of the ARDL model shows that there exists a long term relationship between economic growth and the debt variables. It was evident from the findings that there exists bidirectional causality between public sector external debt and economic growth. Causality between private external debt and economic growth has been found to be insignificant. However, causality between domestic debt and economic growth showed a unidirectional causality from domestic debt to economic growth and not vice versa. Causality tests suggest that impact of domestic debt on economic growth is more effective compared to external debts.

The purpose of this study is to identify the differences between married women's dissatisfaction towards imported and domestic clothing and to test the role of socioeconomic variables on dissatisfaction. Two-piece formal suit was selected as the item, and country of origin of imported suit was not controlled. Sample selection criteria included married women living in Seoul, Korea, between ages 30-59. The data were analysed using factor analysis, paired t-test, and one-way ANOVA. The results indicate, in the Korean clothing market, both international and Korean marketers should be prudent with their price policies and should implement differentiated marketing strategy based on their target market's demogrophic profile. Higher dissatisfaction towards domestic clothing in terms of most factors, under the rapidly globalizing market environment suggests the Korean marketers will be forced to face full-scale harsh competition from international marketers.

In this study, it is quantitatively analyzed for thermal Characteristics of isolation-heat paint which has been supplied to a domestic market through experiments and simulations. In the case of experiment using the container box, it shows 8% decrease on cooling energy consumption in a summer season, but shows increase on heating energy consumption. As a result, the analysis has found increase of energy consumption. As a result of holding simulations with meteorological data of domestic major cities, it shows an increase of energy consumption in domestic condition, and it is hard to expect an energy saving from the isolation-heat paint unless greater air-conditioning load.

Domestic city gas is supplying in an about 10 million household on present 34 city gas companies because is begun to supply regularly after two 1980 years middle. But, result that focus on city gas supply spread and stable supply for supply area and neglects about safety problem, hundreds casualties such as Ahyun explosion accident and Deagu city gas explosion accident were reached in situation that occurred large size calamity occurs it is dizzliness. In the case of advanced nation, can see that accomplish system and progress that in technology after experience major accident. Therefore, grasp problem investigating safety actual conditions for city gas institution and study about solvable plan is required this. Also, must guide reform and level elevation of a domestic company safety technology through induction and development of safety technology that is suitable in supply, domestic real condition etc. Must help in power positivity that is full text executing high-quality safety education about step High firing mechanism safety technology than present safety education.

In this study it compares a Japanese standards which is most similar contents with domestic standards related with the light weight aggregate concrete and derives the fundamental data from the results so that it will be able to refer at maintenance of standards or specifications in future. The case of domestic is the actual more insufficient condition which is described in the standards and the specifications than Japanese standards. For the production of he domestic light weight concrete the development of general standards and construction guides and control of water content ratio of the light weight aggregates become accomplished rightly in quality of construction site.

This study was a result of laboratory test to confirm the porperties of concrete containing the domestic artificial lightweight aggregate. The domestic artificial lightweight aggregate is made with bottom ash which waste material in the thermal power plant. In the experimental result air contents of fresh concrete was measured lower than other artificial lightweight aggregate. This air contents is important for retaining the resistance of freezing and thawing. Therefore air contents of concrete will be considered for retaining the resistance of freezing and thawing when manufacture the concrete containing the domestic artificial aggregate.

When the number of skyscrapers are increased in the domestic, it has increased the need of the outer wall cleaning robot. However, it does not exist the construction specification of the outer wall cleaning robot in the domestic. it is difficult to apply in the domestic that the outer wall cleaning robot. For this reason, it raised the need of the construction specification. And it is urgent that the construction specification of the outer wall cleaning robot is needed to develop in the domestic. Therefore, this study aims to propose the construction specification framework of the outer wall cleaning robot. In the future, this study will be based on the development of the construction specification on the outer wall cleaning robot.

The ICAO AMO global recognition system will be instituted in 2024, with the aim of reducing the certification and surveillance burden on aviation authorities and approved maintenance organizations (AMOs). If the domestic AMO certification and surveillance system is internationally recognized through this system, it may facilitate the rapid development of the domestic MRO industry in South Korea. To ensure international recognition of the domestic AMO system, the AMO surveillance and regulation system must be improved. This study reviewed ICAO policies, standards, guidelines, and leading aviation authorities' regulations and systems with regard to maintenance organization certification and surveillance, and a comparative analysis with the domestic system was conducted. From this, gaps in aviation safety inspection personnel training, qualification, and surveillance were identified, and measures for improving inspection personnel training and organization certification and surveillance system maintenance were elucidated to preemptively respond to the ICAO AMO global recognition system.
