NCS (National Competency Standards) has emerged as an issue of great importance amongst Korean universities and corporations. Although previously used mostly for vocational education purposes at colleges, NCS is currently receiving an increasing amount of attention from 4-year universities as well. In the ever-evolving information economy, the basic workplace skills defined by NCS, which include soft skills such as communication skills, problem-solving skills, and interpersonal skills, have now become more important than specific technical skills. This study analyzes the correlation between the basic workplace skills of NCS with participation in Formula SAE activities, a common component of Capstone design courses across North America and Europe. Data are derived from site visits to Formula SAE competitions, competition-related documents drafted by student participants, and questionnaires administered to student participants at the Formula SAE Lincoln completion and at the Korea KSAE competition. From the study findings, we claim that the basic workplace skills of NCS are closely correlated to participation in Formula SAE activities. Through a survey designed to measure the degree to which Formula SAE activities can enhance an individual's NCS Basic Workplace Skills, we find that these activities overall improved NCS basic workplace skills averaging 4.0 points above in the Likert 5-point scale. For reference the mathematical skills, communication skills, and problem-solving skills displayed statistically significantly correlation with NCS but the remaining 7 skills did not show a statistically strong correlation with NCS comparatively.

The ability of probiotics containing Lactobacillus acidophilus to adhere to the intestinal epithelium may play an important role in colonization of the gastrointestinal tract and preventing enteric pathogen such as enterohemorrhagic E. coli(EHEC O157:H7. In the study, we investigated the adhesion to human intestinal epithelial cells(HT-29) of strains of L. acidophilus(3 from human, 2 from pig, and 1 from calf). All of the tested strains of L. acidophilus were highly observed adhesion ability(from 10$\^$6/ to 10$\^$7/ cfu/mL), compared to L. rhamnosus GG as control. Also, adhered strains of L. acidophilus were significantly preserved in serial wash-out steps. However, no correlation could be observed between cell surface hydrophobicity and adhesion abilities of the tested strains of L. acidophilus. Inhibition of adhesion of EHEC O157:H7 was also examined, a 2 log cycle reduction was observed by all of the tested strains of L. acidophilus. These results suggest that the strains of L. acidophilus with high adhesion ability are resistant to wash-out and adhesion ability inhibition by selected strains of L. acidophilus helps to prevent adhesion of EHEC O157:H7 to intestinal epithelial cells.

In the companion paper (Model Development), an analytical model estimating the available rotation capacity of fully restrained beam-column connections in special steel moment-resisting frames was proposed. In this paper, two limit states were considered as the connection rotation capacity criteria: (i) strength degradation failure when the strength falls below the nominal plastic strength due to the local buckling of the beam's cross-section and (ii) low-cycle fatigue fracture caused by plastic strain accumulation at the buckled flange after only a few cycles of high-amplitude deformation. A series of analyses are conducted using the proposed model with two limit states under monotonic and cyclic loadings. Beam section geometric parameters, such as flange and web slenderness ratios, varied over the practical ranges of H-shapedbeams to observe their effect on the rotation capacity and low-cycle fatigue life of pre-qualified WUF-W connections.

This study was conducted to verify the effect of integrated therapy program on the self-esteem, self-expression, and sexual self-determination of sexually abused women with intellectual disabilities. The subjects of this study were 8 victims who were referred to the Sexual Violence Relief Center for women with intellectual disabilities in K-area. The effectiveness of the program was evaluated to statistical significance though the pre- and post-test using the SPSS Win 25.0 program. The integrated therapy program significantly improved the self-esteem of victims(t=-4.183, p<0.001). Self-expression was significantly improved(t=-5.103, p<0.001). It was also observed that the change in behavior was positively reinforced in the sexual self-determination(t=-26.346, p<0.001). The results of this study suggest that integrated therapy program should be actively used for psychological and emotional healing of sexual assault victims with intellectual disabilities.

First-order cybernetics during the 1940s and 1950s aimed for control of an observed system, while second-order cybernetics during the mid-1970s aspired to address the mechanism of an observing system. The former pursues an objective, subjectless, approach to a system, whereas the latter prefers a subjective, personal approach to a system. Second-order observation must be noted since a human observer is a living system that has its unique cognition. Maturana and Varela place the autopoiesis of this biological system at the core of second-order cybernetics. They contend that an autpoietic system maintains, transforms and produces itself. Technoscientific recreation of biological autopoiesis opens up to a new step in cybernetics: what I describe as third-order cybernetics. The formation of technoscientific autopoiesis overlaps with the Fourth Industrial Revolution or what Erik Brynjolfsson and Andrew McAfee call the Second Machine Age. It leads to a radical shift from human centrism to posthumanity whereby humanity is mechanized, and machinery is biologized. In two versions of the novel Demon Seed, American novelist Dean Koontz explores the significance of technoscientific autopoiesis. The 1973 version dramatizes two kinds of observers: the technophobic human observer and the technology-friendly machine observer Proteus. As the story concludes, the former dominates the latter with the result that an anthropocentric position still works. The 1997 version, however, reveals the victory of the techno-friendly narrator Proteus over the anthropocentric narrator. Losing his narrational position, the technophobic human narrator of the story disappears. In the 1997 version, Proteus becomes the subject of desire in luring divorcee Susan. He longs to flaunt his male egomaniac. His achievement of male identity is a sign of technological autopoiesis characteristic of third-order cybernetics. To display self-producing capabilities integral to the autonomy of machinery, Koontz's novel demonstrates that Proteus manipulates Susan's egg to produce a human-machine mixture. Koontz's demon child, problematically enough, implicates the future of eugenics in an era of technological autopoiesis. Proteus creates a crossbreed of humanity and machinery to engineer a perfect body and mind. He fixes incurable or intractable diseases through genetic modifications. Proteus transfers a vast amount of digital information to his offspring's brain, which enables the demon child to achieve state-of-the-art intelligence. His technological editing of human genes and consciousness leads to digital standardization through unanimous spread of the best qualities of humanity. He gathers distinguished human genes and mental status much like collecting luxury brands. Accordingly, Proteus's child-making project ultimately moves towards technologically-controlled eugenics. Pointedly, it disturbs the classical ideal of liberal humanism celebrating a human being as the master of his or her nature.

The purpose of this study was to examine mathematical performance predictions with gifted behavior ratings by teachers and parents. The participants of this study were 787 elementary 5th and 6th grade gifted students who took the mathematical performance test. This study asked gifted teachers and parents to rate gifted behaviors of these gifted students with using SRBCSS-R (Renzulli et al., 2002, 2009). The results indicated that gifted teachers rated gifted behaviors of the 5th grade gifted students higher than the 6th grade gifted students, except in 'mathematical characteristics.' Gifted teachers rated 'learning' gifted behaviors of male gifted students higher than those of female gifted students. In the meanwhile, parents of the 5th grade gifted students rated gifted behaviors higher than parents of the 6th grade gifted students in 'learning' and 'motivation.' In comparing the gifted behavior ratings by gifted teachers and parents, there were significant differences in 'learning' and 'motivation' ratings. That is, gifted teachers rated significantly higher 'learning' and 'motivation' of gifted students than parents. When this study explored the prediction of gifted behavior ratings by gifted teachers and parents on mathematical performances of gifted students, 'learning' and 'mathematical characteristics' ratings by gifted teachers predicted the mathematical performances of gifted students.

This case study investigated the effects of sensory integration therapy on social behaviors and feeding of children with intellectual disabilities who lack sensory processing abilities. The study was conducted done from September to December, 2016, and an ABA(two sessions, nine sessions, two sessions/total 13 sessions) design was used among Single Subject Research Design. Nine sessions of sensory integration program were conducted for 50 minutes each, and Wilbarger's Protocol was employed 2-3 times per day. To understand children's basic development levels, observation evaluation of each area and social maturity scale were conducted in the early stage. To Understand the children's sensory processes ability, a Sensory Profile(SP) was developed, while the activities of daily living and task performance ability scale were evaluated using the Functional Independence Measure for children(WeeFIM) and Canadian Occupational Performance Measure(COPM), respectively. Search behavior and feeding, which are social behaviors of children, were evaluated through observation. The results showed that the sensory integration program improves social behaviors of children and enables them to eat. The children's feeding was stable from the 5th session after the intervention, and the search behaviors started to change from 3 weeks after the intervention and became stable after 7 weeks. These results indicate that the sensory integration program is effective in mediating difficulties that children with intellectual disabilities who lack sensory processing ability experience in daily living.

Mesna has been used with ifosfamide to prevent urotoxicity in the treatment of testicular cancers. This drug also protected the toxicities of adriamycin without compromising cytostatic activity. With an idea of radioprotective role of sulfhydryl group of radioprotectors and of mesna decreasing the toxic effect of adriamycin which produces free radicals, mesna and radiation were administered to mice to study the protective effect of this drug and to identify the difference in regenerative capacity of the germ cells in the testis between radiation-treated and both mesna-and radiation-treated groups. The shape and numbers of spermatogenic cells in the seminiferous tubules were examined every week after irradiation. In both groups, initial reduction and later recovery in germ cell numbers and shape was observed. The lowest germ cell number was found around three weeks after irradiation. Mean germ cell number of the mesna-treated group was significantly higher than radiation-treated group at all observed periods (p<0.05). More competent regeneration was present in mesna-treated group. These results suggest that mesna protect the testis from radiation injury. Further study will be necessary to identify whether mesna protects other tissues from radiation and it does not hamper tumor control.

An experiment was conducted to investigate the effects of feeding Bupleurum falcatum L.(BFL) on performance, blood component and hormonal secretion in broiler breeder hens. A total of 800 broiler breeder hens were allotted to four treatments(BFL ; 0, 0.5, 1.0, 2.0%) with four replications for eight weeks. Weight gain was not significantly different between the groups in growing period($20{\sim}24$ weeks), but egg production and egg mass of broiler breeder hens fed BFL were significantly(p<0.05) higher than those of the control groups in laying period($24{\sim}28$ weeks). Dietary BFL did not affect serum triglyceride concentration, whereas serum cholesterol concentration was significantly increased(p<0.05) in 2.0% BFL-fed groups. No statistical differences were found in serum glucose, Ca, P, Mg, total protein, albumin, GGT, AST, ALT and BUN concentrations. However, albumin/globulin ratio was statistically higher in BFL-fed groups compared to the control groups(p<0.05). Serum estrogen concentrations were significantly increased by feeding a diet containing 0.5% BFL, but progesterone were not influenced. Serum IGF-I of BFL groups was greater than that of control groups at 28 weeks(p<0.05). In conclusion, the results suggest that the dietary addition of BFL into broiler breeder diets improved egg production, serum estrogen and IGF-I concentration, and decreased serum cholesterol concentration and albumin/globulin ratio.
