This study is to investigate the researches with handball game by research domain and methodological aspects during its 10years (1990-2000). As results of analyzing methodological structure, characteristics of subjects by research domain and the number of articles statistical techinics by years. 1. the researches of handball games need longitudinal study with academic arena in accordance with the globalization trends. 2. The number of case and representative is to provide academic suport therefore it is nesessary to provide effect size for handball games for identify susficious questions sample sizes for students and professors in the field of measurement & evaluation 3. It is proud to acculately need to test methodological research domains in order for performing handball related researches journal to be acknowledged by scholars in other parts of the world. the focus must be on equality rather than on quantity.

<P>Organic-inorganic hybrid bipolar field-effect transistors (HBFETs) comprising a layer of p-type organic poly(3-hexylthiophene) (P3HT) separated from a parallel layer of n-type inorganic zinc oxide (ZnO) were demonstrated by solution processing. In order to achieve balanced hole and electron mobilities, we initially optimized the hole-transporting P3HT channel by the addition of the polar non-solvent acetonitrile (AN) to P3HT solutions in chloroform, which induced a selfassembled nano-fibril morphology and an enhancement of hole mobilities. For the electron channel, a wet-chemically-prepared ZnO layer was optimized by thermal annealing. Unipolar P3HT FET with 5% AN exhibited the highest hole mobility of 7.20 x 10(-2) cm(2)V(-1)s(-1) while the highest electron mobility (3.64 x 10(-2) cm(2)V(-1)s(-1)) was observed in unipolar ZnO FETs annealed at 200A degrees C. The organic-inorganic HBFETs consisting of the P3HT layer with 5% AN and ZnO annealed at 200A degrees C exhibited well-balanced hole and electron mobilities of 1.94 x 10(-2) cm(2)V(-1)s(-1) and 1.98 x 10(-2) cm(2)V(-1)s(-1), respectively.</P>

Structural assessment of the tetramerization domain and DNA-binding domain of CP2c
Jo, Ku-Sung,Ryu, Ki-Sung,Yu, Hee-Wan,Lee, Seu-Na,Kim, Ji-Hun,Kim, Eun-Hee,Wang, Chae-Yeon,Kim, Chan-Gil,Kim, Chul Geun,Won, Hyung-Sik Korean Magnetic Resonance Society 2018 Journal of the Korean Magnetic Resonance Society Vol.22 No.4
Although the transcription factor CP2c has been recently validated as a promising target for development of novel anticancer therapy, its structure has not been solved yet. In the present study, the purified recombinant protein corresponding to the tetramerization domain of CP2c appeared to be well folded, whereas the Elf-1 domain showed a largely unfolded conformation. Particularly, the Elf-1 domain, which contains the putative DNA-binding region, showed a conformational equilibrium between relatively less-ordered and well-ordered conformers. Interestingly, addition of zinc shifted the equilibrium to the relatively more structured conformer, whereas zinc binding decreased the overall stability of the protein, leading to a promoted precipitation. Likewise, a dodecapeptide that has been suggested to bind to the Elf-1 domain also appeared to shift the conformational equilibrium and to destabilize the protein. These results constitute the first structural characterization of the CP2c domains and newly suggest that zinc ion might be involved in the conformational regulation of the protein.
