  • The ${\beta}$-turn has been implicated as an important conformation for biological recognition of peptides or proteins. Benzodiazepine classes have been known as one of the non peptide ${\beta}$-turn mimic scaffolds. We have developed an efficient approach for the synthesis and derivatization of a scaffold of hydroxytetrahydrodizepinone class in order to screen compound library in various protein targets for new lead generations as well as for structure activity relationships of the scaffold.

  • The purpose of this study was to offer objective information about standard of selecting and training fashion models by verifying anthropometric characteristics and comparing with general women. Total forty eight fashion models (M=20.08yr ; SD=1.7) were recruited by convenience sampling. Thirty eight items of participants were measured by manual of International Society for the Advancement of Kinanthropometric (ISAK). Mean and standard deviation of 38 items and also factor of somatotype (endomorph, mesomorph, ectomorph) were calculated. In the result, somatotype of fashion model was endomorphic ectomorphy, less muscle and taller height. Conclusionally, this study indicated that there is less mesomorphy rating related to muscle quantity, bone mass in somatoplot. However, it is necessary to provide the program enhancing the physical activity with model department.

  • Visfatin (Nampt/PBEF) plays a pivotal role in the salvage pathway for $NAD^+$ biosynthesis. Its potent inhibitor, FK866, causes cellular $NAD^+$ levels to decline, thereby inducing apoptosis in tumor cells. In an effort to improve the solubility and binding interactions of FK866, we designed and synthesized IS001, in which a ribose group is attached to the FK866 pyridyl ring. Here, we report the crystal structure of rat visfatin in complex with IS001. Like FK866, IS001 is positioned at the dimer interface, and all of the residues that interact with IS001 are involved in hydrophobic or ${\pi}-{\pi}$-stacking interactions. However, we were unable to detect any strong interactions between the added ribose ring of IS001 and visfatin, which implies that a bulkier modifying group is necessary for a tight interaction. This study provides additional structure-based information needed to optimize the design of visfatin inhibitors.

  • This paper examines the relationship and ideas of Hannah Arendt and Philip Roth including how they met, their correspondence and intellectual parallels, particularly in their shared criticism of Jewish ideals and culture in Europe and North America. It analyzes similarities in their careers and texts, especially between Eichmann in Jerusalem and Operation Shylock, as well as The Ghost Writer, while measuring their reception as social commentators and writers. Kafka was an important figure for both writers, Arendt's earliest writing engaged with the significance of Kafka in understanding and criticizing twentieth century political and cultural values in Europe. For Roth, Kafka offered a similar critique of moral principles he found corroded in North American Jewish life. Arendt connected with other writers, notably Isak Dinesen, W. H. Auden, Randall Jarrell and William Styron who further linked the two: he knew both Arendt and Roth and cited, incorrectly, a work by Arendt as the source for the key incident in his 1979 novel Sophie's Choice. He claimed it was Eichmann in Jerusalem; it was Arendt's The Origins of Totalitarianism. Arendt's reaction to Roth's fiction, however, remains a mystery: she died in 1975, before Roth began to seriously and consistently engage with Holocaust issues in works like The Ghost Writer (1979) and Operation Shylock (1993). Yet even in death they are joined. Their graves are only steps apart at the Bard College Cemetery in Annandale-on-Hudson, New York.

  • The purpose of this study is to investigate whether there are differences in physique characteristics between the excellent domestic player groups in each sport player's, to prevent epidemiologic damage of musculoskeletal system and to provide fundamental data to improve performances for players. This study has performed for total 60 student players from Y University in Yongin, Gyeonggi-do, consists of 20 Kendo players, 20 Judo players and 20 Taekwondo players. We measured the length and circumference of arm, leg, body using Martin anthropometer to collect the data for 3 groups. There was significant difference in lower left arm length between player groups(p<.01), and Kendo players' right side femoral were longer than other 2 groups for leg length measurement(p<.01). Judo players' circumference for right/left stretched arm/bent upper arm were thicker than other 2 groups(p<.01). Taekwondo players' chest circumference were smaller than other 2 groups(p<.01), and Taekwondo players' right/left femoral circumference were thinner than other 2 groups(p<.05). From this study, it was found that there are physique characteristics differences between the Kendo, Judo and Taekwondo player groups. This indicates that repeated exercise for each sport player causes physique change, and it may cause epidemiologic damage of musculoskeletal system. It is recommended to perform balancing exercise prior to main exercise.
