Inhibitor of DNA binding protein or inhibitor of differentiation(Id) is largely considered as positive and/or negative regulators of proliferation, differentiation, angiogeneisis, and apoptosis. The four Id genes(Id1, Id2, Id3, and Id4) were known in mammals. However, little is known about the expression and function of these genes in reproductive physiology. Among them, this study was conducted to analyze the expression pattern of Id3 mRNA on folliculogenesis in rat ovary. After PMSG administration, the ovaries were obtained at 3, 6, 12, 24, 36, and 48hrs, fixed, dehydrated, and paraffin embedded. For in situ hybridization, anti-sense and sense Id3 cRNA probes were prepared and applied to the ovarian section. The ovarian sections were coated with NTB-2 emulsion. After that, the slides were developed and counterstained with hematoxylin and eosin staining. The hybridization signal was estimated on a scale of 1+ to 4+. In oocyte, the intensity of Id3 mRNA in primordial and primary follicles was scored at ${\geq}2+$, but the intensity was less than 1+ in secondary, dominant, and preovulatory follicles. In granulosa cells, the Id3 mRNA was strongly expressed(3+ or 4+) in dominant and preovulatory follicles. Taken together, Id3 mRNA was expressed specifically at follicle stages and follicular tissue and might be closely related with follicle development.

The stability condition and wideband characteristics of 3D ID-FDTD algorithm which has low dispersion error with isotropic dispersion are presented in this paper. 3D ID-FDTD method was proposed to improve the defect of the Yee FDTD such as the anisotropy and large dispersion error. The published paper calculated the stability condition of 3D ID-FDTD algorithm by using numerical method, however, it is thought that the examples were not sufficient to verify the stability condition. Thus, in this paper, various simulations are included in order to hold reliability under the conditions that the plane wave propagation is assumed with a single frequency and a wideband frequency. Also, the 3D ID-FDTD algorithm is compared to those that have the similar FDTD algorithm with ID-FDTD such as Forgy's method and non-standard FDTD method in a wideband. Finally, the radar cross section(RCS) for the large sphere with high dielectric constant is calculated.

A method of DID generating step is suggested for applying the XML technology to the information data extracted from the Legacy databases. The IDREF-ID attribute reference modeling is used for representing the complex relationship between tables and excluding the prearranged step of ID insertion. ID Insertion procedure is performed in parallel with investigating the relationship between the tables and the frequent search direction between the table data. As a result, ID insertion procedure can be performed simultaneously with understanding of the IDREF-ID relationship between tables, and DID are also generated.

Plant residues serve as substrates for the proliferation and overwintering of plant pathogenic fungi in soil. Effects of the biocontrol fungus Trichoderma harzianum on the colonization of wheat straw by the plant pathogenic fungus Fusarium solani were investigated under different soil moisture regimes (-50 vs. -500 kPa) in non-sterile soil. T. harzianum ThzID1-M3 and/or F. solani were added along with wheat straw to non-sterile soils. ThzID1-M3, other Trichoderma species, and F. solani were monitored for a 21-day period using quantitative PCR. ThzID1-M3 reduced the colonization of F. solani on wheat straw (p < 0.05) under both moisture regimes, and F. solani reduced the colonization by ThzID1-M3 and other Trichoderma species (p < 0.05), thus suggesting competitive inhibition between ThzID1-M3 and F. solani. Colonization by ThzID1-M3 and generic Trichoderma was improved in the wet soil (p < 0.05), but colonization by F. solani did not differ between the two moisture conditions. Thus, the inhibitory effect of ThzID1-M3 was greater in the wet soil (p < 0.05). The growth competition between ThzID1-M3 and F. solani to colonize plant debris suggests that the biocontrol fungus T. harzianum may reduce the potential of the plant pathogen, F. solani, to survive and proliferate on crops.

Purpose: The aim of this study was to identify perception, use status and factors influencing use of medical alert identification (ID) in diabetic patients who are on insulin. Methods: A survey was conducted from December 2013 to April 2014 with 198 people who were asked to participate in the survey. Results: The medical alert ID perception score was 3.54 on a 5-point scale. Most of respondents (82.8%) knew about the medical alert ID, but only 23.2% of respondents wore a medical alert ID and only 43.5% of respondents always wore a medical alert ID. Perception and frequency of possession were positively correlated (r=.41, p<.001). The most influential factor for the possession of a medical alert ID was the perception of the medical alert ID (${\beta}=.41$, p<.001). The perception of the medical alert ID explained 17% of variance in possession of a medical alert ID. Conclusion: Most of diabetic patients who take insulin received education about hypoglycemia and knew about the medical alert ID, but only few of them wore a medical alert ID. Findings from this study indicate that perception is an important variable related to possession of a medical alert ID in this population.

in 1984 Shamir proposed the concept of ID(identity)-based cryptosystem and digital signature scheme wich does not require any public file for storing the user' s public keys. In this paper, the concept of the ID-based cryptosystem based on discrete logarithm problem using the conven-tional public-key cryptosystems is described, and the implementation method of the ID-based cryptosystem is also presented. The new digital signaturw schme based on the ID-based crypto-system is proposed and possible atacks are considered and analyzed for the security of digital signature scheme. The proposed ID-based schemes are particularrly useful for smart card and personal identification card application.

The effect of internal donor(ID) in the heterogeneous Ziegler-Natta catalyst on the ethylene-1-butene copolymerization and the molecular structure of the resulting copolymer was investigated. $SiO_2$-supported $TiCl_4$ catalysts having ID/Ti molar ratio of 0.5 were prepared with ethyaluminium dichloride, magnesium alkyl, 2-ethyl-1-hexanol and $TiCl_4$. Three different IDs were employed such as ethylbenzoate(EB), diisobuylphthalate(DIBP) and dioctylphthalate(DOP). ID-added catalyst showed a larger fraction of Ti(+3) compared to that of no ID-added catalyst. The EB-added catalyst showed the highest activity in copolymerization. Xylene soluble value decreased by more than 50 % with ID-added catalysts compared to that of no ID-added catalyst. Crystaf analysis showed the chemical compositional distribution of PE copolymer was improved in the case of DIBP-added catalyst significantly. It could be explained that the presence of ID could make more even active sites and block the non-stereospecific active sites.

With the increase of number of internet services due to development of internet, it becomes a critical issue to appropriately manage the personal information about user's identity, that is ID information that service providers collect in terms of user's convenience improvement and privacy protection. But the existing ID information management models are service provider-centric or they insufficiently provide ID information management functions, so that they have not been satisfying user's requirement. In this paper, by establishing user-centric concept in we information management, we propose the new user-centric ID information management model in which user can make use of the internet service more conveniently and eventually enhance user's privacy.
