Polyimide films have excellent thermal stability, reliable mechanical properties and low dielectric constant. Therefore, this material is widely used in many industrial fields such as microelectronics, flexible circuits, semiconductor products and aerospace materials. In space applications, earth-orbiting hardware operates in environments that generally include neutral particles, charged particles such as trapped protons and electrons, solar protons, and cosmic rays. Under these conditions, polyimide films were changed in the optical, electrical and mechanical properties. Therefore, in this study, we evaluated the effects of electron beam irradiation on polyimide. The O-H functional groups were created on the polyimide film surface in the results of FT-IR spectra. And it was found that the dielectric constants were changed as a function of electron beam dose.

Recently, cloud computing market is growing geometrically in both private and public area, and many global companies in various domains have developed and provided cloud computing services. In such situation, Korean government made multiple plans for domestic cloud computing industry. However, most research institutes have focused on market size and status information, which makes actual effectiveness of cloud computing service hard to recognize. In this study, we define cloud computing Industry by rearranging Input-Output table published by the Bank of Korea to use Input-Output Analysis. The Input-Output Analysis was devised in 1963 by Leontief and it is used in many fields of study until now. It produces various coefficients that are able to identify production-inducing effect, value-added effect, labor-inducing effect, front and rear chain effect. The analysis results show that production-inducing effect, front and rear chain effect of cloud computing industry is low compared to other industries. However, cloud computing Industry possesses relatively high value-added effect and labor-inducing effect. It is because industry magnitude of cloud computing is smaller than other industries such as manufacturing, chemical industries. The economic effects of the cloud computing industry are not remarkable, but this result is significant to emerging markets and industries and presents the fresh way of analyzing cloud computing research field.

Vietnam's Oil and gas industry make a significant contribution to the Gross Domestic Product of Vietnam. The ongoing COVID-19 pandemic has hit every industry hard, but perhaps the one industry which has taken the biggest hit is the global oil and gas industry. The purpose of this article is to examine how the COVID-19 pandemic affects the share price of the Vietnam Oil and Gas industry. The event study method applied to Oil and Gas industry index data around three event days includes: (i) The date Vietnam recognized the first patient to be COVID-19 positive was January 23, 2020; (ii) The second outbreak of COVID-19 infection in the community began on March 6, 2020; (iii) The date (30/3/2020) when Vietnam announced the COVID-19 epidemic in the whole territory. This study found that the share price of the Vietnam Oil and Gas industry responded positively after the event (iii) which is manifested by the cumulative abnormal return of CAR (0; 3] = 3.8% and statistically significant at 5 %. In the study, event (ii) has the most negative and strong impact on Oil and Gas stock prices. Events (i) favor negative effects, events (iii) favor positive effects, but abnormal return change sign quickly from positive to negative after the event date and statistically significant shows the change on investors' psychology.

Water is an essential element required for the survival of 6 billion human beings around the world, and it has limited mobility. The importance of water industry has grown considerably, as its forecasted market size is expected to increase from $336 billion in 2007 to $865 billion in 2025, respectively. In 2003, the domestic water market was estimated to be worth 11 trillion won. However, according to the estimates of this research, the result above was overestimated by 2 trillion won. The economic ripple effects of newly defined water industry based on the input-output data from 2000 to 2008 were trivial, as the price effects of water industry was considerably minor at only 0.12%. To successfully implement policies to enhance the water industry, the market price mechanism must operate and function properly. Nevertheless, the impact of water's market prices on the economy upon application is projected to be trivial.

The purpose of this study was to investigate the quality of two different commercial Bangpungtongseong-san (BTS) extract granules (BTS-2 and BTS-3) by comparing with BTS decoction (BTS-1). The contents of characterizing components and biological activities of two different commercial BTS extract granules were compared with those of the BTS decoction. The contents of characterizing components were analyzed with HPLC. The antioxidative effects were determined by measuring 2,2-diphenyl-1-picrylhygrazyl (DPPH) radical scavenging and superoxide dismutase (SOD)-like activity. Also, we compared the effects on lipid accumulation and reactive oxygen species (ROS) production during differentiation of 3T3-L1 preadipocytes. The contents of five components except liquiritin and sennoside A were higher in BTS-1. The DPPH radical scavenging and SOD-like activity were higher in BTS-1. BTS-1 significantly inhibited lipid accumulation during differentiation of 3T3-L1 preadipocytes and showed stronger effects than BTS-2, BTS-3. In addition BTS-1 showed stronger inhibition effects on ROS production during differentiation of 3T3-L1 preadipocytes than BTS-2, BTS-3. These results indicate that BTS decoction has strong biological activities than commercial BTS extract granules. It is also consistent with the contents of characterizing components.

In Korea, female workforce has reached more than 40% of total working population, but the effects of work on spontaneous abortion are yet to be examined. This study as conducted to investigate the occupational effects on spontaneous abortion. Medical insurance claim data were used to examine the effects of the employment status and industry of employment on spontaneous abortion. The study population was composed of females, aged $15{\sim}44$, who were the beneficiary of medical insurance in the month of June, 1993. The working females covered by medical insurance for industrial workers, had the highest age-adjusted Spontaneous Abortion rate (SAB rate=claim frequency of spontaneous abortion/claim frequency of complication of pregnancy, childbirth and the puerperium), 6.65% whereas female dependants of medical insurance for industrial workers had the lowest age-adjusted SAB rate, 4.54%. Among industrial workers, the workers in manufacturing industry had the highest age-adjusted Spontaneous Abortion ratio(SAB ratio=claim frequency of spontaneous abortion/claim frequency of completly normal delivery), 43.2/100 whereas those in financing and service industry had age-adjusted SAB ratio, 16.2/100 and 20.5/100, respectively. The results of the study suggest the adverse effect of manufacturing Industry on reproduction. Work environments such as chemical exposures, overwork, awkard posture, and job stress should be further studied for their effects on reproductive functions of female.
