Human factors engineering design guidelines for main control rooms(MCR) in nuclear power plants(NPP) have been applied to optimize human-machine interface(HMI) between operators and their equipment on the basis of physical, physiological and cognitive aspects. However, the HMI design for MCR is not found to be sufficient to maximize operators' performance since the operators in the MCR experience excessive stress due to the environmental factors such as inappropriate interiors and illumination. Therefore, well-designed environment of the MCR may be equally important to improve human performance in the MCR. The objectives of the study are two-fold: (1) to propose an interior design of SHIN-KORI 1 2 for pleasant and comfortable working environments, and (2) to design indirect lighting system to enhance visibility and productivity. The human factors engineering checklists were developed to examine whether or not the proposed human-environment design for SHIN-KORI 1 2 satisfies the regulations and guidelines presented by NUREG-0700 Revision 1. The implications of the human-environment design are discussed in detail.

The purpose of this study is to investigate the symbolic meaning in body image and fashion style portrayed in Korea and American movies in aspects of sex, race, nature, and technology. The researcher analyzed movies in Korea and USA, and the results were as follows. In aspects of sex, movies portrayed new masculinity and femininity escaped from previous gender stereotypes, and the clothing styles characterized sex identity and sex roles. In aspects of race, more various races appeared in America movies than Korea＇s, and the appearance and stereotypes related with race were blurred by the globalization and the change of film market environments. In aspects of nature, Korea movie portrayed the human being as lyrical appearance in nature, and America movie expressed the human as a strong men conquering the nature in adventure movie or super human image combined with nature thing which endowed nature＇s superior characteristics to human body in fantasy and science fiction movies. In aspects of technology, the human bodies were described as cyborg, alien, or super human, which symbolized the do-identification in digital world, de-boundarization between human and machines, and the human＇s uncertainty.

A rapid and sensitive method has been developed to detect a-fetoprotein (AFP) in human serum by a two-site sandwich enzyme-linked immunosorbent assay (ELISA) with monoclonal antibodies (MAbs) for human AFP within 1 h. To obtain the most sensitive and reliable MAbs. 12 kinds of MAbs (HPJ1 to HPJ12) as a capture antibody and 4 kinds of horseradish peroxidase (HRP) conjugated MAbs as a tracer antibody were investigated. Among these, only HPJ 10-HRP conjugated HPJ 1 (HPJ 10-HPJ $1^*$) and HPJ 11-HRP conjugated HPJ 10 (HPJ 11-HPJ $10^*$) were chosen as candidates based on the linearity of the standard curve and the sensitivity of the assay. To further characterize these two pairs. MAbs against human AFP were purified from hybridoma cells. conjugated with HRP. and then characterized to optimize the two-site sandwich ELISA The HPJ 10-HPJ $1^*$ pair showed a sensitivity of 1 ng/ml and a better reproducibility than the HPJ 11-HPJ $10^*$ pair when the human sera were incubated at $37^{\circ}C$ for 30 min. The results obtained for 480 randomly selected human sera showed 0~20 ng/ml of AFP values for the normal human sera. To test the utility of our kit, AFP concentrations were determined for 951 human sera (including 85 normal sera, 480 random blood sera, 213 HBsAg-positives. 50 anti-HCV antibody positives. and 47 malignant diseases) and compared with other commercially available AFP detecting kits. These results show that the present two-site sandwich ELISA method is a rapid, sensitive, and reliable procedure for detecting AFP in human serum.

This study is a theoretical account of HRs requirements in educational institutions in light of the growing influence of digital technology on human rights. It intends to reveal prominent human and civilizational values encapsulated in modern human rights regulations. It dwells on educational and societal requirements for educational inclusion in the school and university curricula in light of changes that have taken place in HRs in the digital age. Relying on the descriptive documentary research design, the study concluded that HRs are inherently moral duties and fixed values. They include the importance of tolerance, freedom, peace, justice, science, work, and equality. Because education is arguably based on human and civilized values, educational foundations require intake of awareness, systematic integration and responsibility from all academic and community institutions, including family and media institutions. The article closes on a note of how technology has impacted human rights in the digital age. It provides implications and recommendations to pedagogies accordingly.

The exopolysaccharide (EPS) produced by Bacillus amyloliquefaciens GSBa-1 was isolated and purified by ethanol precipitation, and DEAE-cellulose and Sepharose CL-6B chromatographies. The molecular mass of the purified EPS was determined to be 54 kDa. Monosaccharide analysis showed that the EPS was composed of predominantly glucose, and it was further confirmed by NMR spectroscopy to be ${\alpha}-glucan$ that consisted of a trisaccharide repeating unit with possible presence of two ${\alpha}-(1{\rightarrow}3)$ and one ${\alpha}-(1{\rightarrow}6)$ glucosidic linkages. Microstructural analysis showed that the EPS appeared as ellipsoid or globose with a smooth surface. The EPS had a degradation temperature at $240^{\circ}C$. Furthermore, the EPS had strong DPPH and hydroxyl radical scavenging activities, and moderate superoxidant anion scavenging and metal ion-chelating activities. This is the first characterization of a glucan produced by B. amyloliquefaciens with strong antioxidant activity. The results of this study suggest the potential of the EPS from B. amyloliquefaciens GSBa-1 to serve as a natural antioxidant for application in functional products.
