PVA 처리에 따른 해도형 나일론 극세사 부직포 인조피혁의 특성 분석
남택욱,이필규,이재민,이유림,이승구,Nam, Taek Uk,Lee, Pil Gyu,Lee, Jaemin,Lee, Yu Rim,Lee, Seung Goo 한국섬유공학회 2021 한국섬유공학회지 Vol.58 No.3
In this study, a leatherette was manufactured using sea-island type nonwoven nylon microfiber. To increase the flexibility of the leatherette, the nonwoven fabric was preimpregnated in a polyvinyl alcohol (PVA) solution. The PVA-impregnated nonwoven seaisland type nylon microfiber was treated with a polyurethane (PU) solution and then the elution process was performed to remove PVA and co-PET using a NaOH solution. The morphologies of the nonwoven fabrics before and after elution of PVA and co-PET were observed by scanning electron microscopy (SEM). The pliability of the nonwoven fabric was evaluated using flexibility and stiffness tests before and after each treatment. The leatherette with the PVA-treated nonwoven fabric showed more pores and gaps in its morphologies and higher flexibility in the stiffness test. Finally, mechanical properties were analyzed based on tensile properties and dynamic modulus.

This paper empirically explores the effects of various government policy instruments on innovation firms` productivity using Korean 2008 and 2010 Community Innovation Survey data conducted by the STEPI. The empirical results summarized as follows. First, government policy variables are found to be endogeneous, which implies that simple OLS estimation of the productivity model should produce biased results and thus lead to inappropriate policy suggestions. Second, empirical results shows that most government technology promotion policies are positively associated with firm productivity directly, implying that the policies cause to correct market failure, rather than lead to government failure. This indirectly means that the government policies promote technology development activities, rather than crowd out them. Third, using the non-InnoBiz firm sample, only one policy variable is found to be statistically significant, but for the Inno-Biz firm sample, all estimated coefficients except two government policy variables are found to be significant. This implies that productivity effects of government policy can be mainly due to those from Inno-Biz firms.

Through the interviews with the persons who are in charge of the administration of the sports centers, the following results were analyed about their present administration conditions such as facilities, profits, wages, utilities, the present condit management, and cost. 1) The profits of sports centers are strongly influenced by locations. Especially, the ones with more convenient, nearby residential areas, and shoppin places in the same building attract more people. 2) Most of the sports centers in Taejon have been experiencing some loss in management for last three years. For instance, M Sports Center has experienced 16.6% decrease in profit in the similar way with others, such as 37.2% decrease at S Sports Center, and 12.8% decrease in C Sports Center. This is not usual if one considers the fact the consumer prices index has been increasing about 5.6% each year. The major reason for this situation is that a lot of sports centers, including ones within new department stores have opened, which increased the competition among the sports centers, resulting lowering prices in order to attract more members. 3) The wages take fairly large portion of over all income in sports center. For example, in case of M Sports Center, wages are 49.1% of total income. Others are not much different, S Sports Center 50.7%, C Sports Center 38.4%. Thus, most sports centers are employing more and more of part time trainers rather than full times. 4) In utility fees(gas, electricity, water supply, etc), the public gyms are offered 45% lower prices than other sports centers; Utility fees in M Sports Center is 37.7% of total incoms, S Sports Center 43.2%, and Sports Center 33.2%. If government subsidies are offered for sports centers, it will greatly ease the pain that most sports centers are having in management. 5) The physical promotion fees that each commercial sports centers have paid each year up to 1999, which are supposed to their total income, have been supporting only the public sports centers that are built by the government. This has worsened the commercial sports centers that already have enough problems in maintaining the facilities. Therefore, government should offer subsidies not only to the public sports centers, but also to the commercial sports centers as well for the benefit of the general public who want to use the facilities. 6) For some of the programs of the sports centers, it is found that the administrations are trying to just maintain the programs rather that trying to provide better ones for the members due to the short of budget. 7) As far as the qualifications of trainers are concerned, 51.7% of them are part time employees, who are not experts. For a closer look M Sports Center has 13 part time employees and of 25 trainers, and among them 18 trainers have finished undergraduate curriculum, and the rest of them have graduated from high school. For S Sports Center, 10 out of 21 trainers are working as part time trainers, and among them, 10 of them finished undergraduate curriculum, and the rest of them have finished high school. C Sports Center is not much different. Half of their trainers are part time workers and 5 out of 12 trainers have finished undergraduate curriculum, and the rest of them have graduated from high school. 8) For administration, only M Sports Center's supervisor is a physical education expert. The other two supervisors who are not experts in physical education have expressed their concerns and limits in managing the trainers and research and development. * A thesis submitted to the committee of Graduate School, Kong Ju National University in partial fulfillment of the requirements for the degree of Master of Arts Conferred in February 2001.
