It is well known that an integral domain D is a UFD if and only if every nonzero prime ideal of D contains a nonzero principal prime. This is the so-called Kaplansky's theorem. In this paper, we give this type of characterizations of a graded PvMD (resp., G-GCD domain, GCD domain, $B{\acute{e}}zout$ domain, valuation domain, Krull domain, ${\pi}$-domain).

Let R be a ring in which Nil(R) is a divided prime ideal of R. Then, for a suitable property X of integral domains, we can define a ${\phi}$-X-ring if R/Nil(R) is an X-domain. This device was introduced by Badawi [8] to study rings with zero divisors with a homomorphic image a particular type of domain. We use it to introduce and study a number of concepts such as ${\phi}$-Schreier rings, ${\phi}$-quasi-Schreier rings, ${\phi}$-almost-rings, ${\phi}$-almost-quasi-Schreier rings, ${\phi}$-GCD rings, ${\phi}$-generalized GCD rings and ${\phi}$-almost GCD rings as rings R with Nil(R) a divided prime ideal of R such that R/Nil(R) is a Schreier domain, quasi-Schreier domain, almost domain, almost-quasi-Schreier domain, GCD domain, generalized GCD domain and almost GCD domain, respectively. We study some generalizations of these concepts, in light of generalizations of these concepts in the domain case, as well. Here a domain D is pre-Schreier if for all $x,y,z{\in}D{\backslash}0$, x | yz in D implies that x = rs where r | y and s | z. An integrally closed pre-Schreier domain was initially called a Schreier domain by Cohn in [15] where it was shown that a GCD domain is a Schreier domain.

On June 27, 2002 Canadian Internet Registration Authority (CIRA) launched dot-ca domain name dispute resolution service through BCICAC and Resolution Canada, Inc. The Domain name Dispute Resolution Policy (CDRP) of CIRA is basically modelled after Uniform Domain Name Dispute Resolution Policy(UDRP), while the substance of CDRP is slightly modified to meet the need of Canadian domain name regime and its legal system. Firstly, this article examined CIRA's domain name dispute resolution policy in general. It is obvious that the domain name dispute resolution proceeding is non-binding arbitration to which arbitration law does not apply. However it still belongs to the arbitration and far from the usual mediation process. Domain name arbitrators render decision rather than assist disputing parties themselves reach to agreement. In this respect the domain name arbitration is similar to arbitration or litigation rather than mediation. Secondly it explored how the panels applied the substantive standards in domain name arbitration. There is some criticism that panelists interprets the test of "confusingly similar" in conflicting manner. As a result critics assert that courts' judicial review is necessary to reduce the conflicting interpretation on the test of substantive standards stipulated in paragraph 3 of CDRP. Finally, it analysed the court's position on domain name arbitral award. Canadian courts do not seem to establish a explicit standard for judicial review over it yet. However, in Black v. Molson case Ontario Superior Court applied the UDRP rules in examining the WIPO panel's decision, while US courts often apply domestic patent law and ACPA(Anticyber -squatting Consumer's Protection Act) to review domain name arbitration decision rather than UDRP rules. In conclusion this article suggests that courts should restrict their judicial review on domain name administrative panel's decision at best. This will lead to facilitating the use of ADR in domain name dispute resolution and reducing the burden of courts' dockets.

Ferroelectric properties are governed by domain structures and domain wall motions, so it is of significance to understand domain evolution processes under mechanical stress. In the present study, in situ piezoresponse force microscopy (PFM) observation under compressive stress was carried out for a near-morphotropic PZT. Both $180^{\circ}$ and $non-180^{\circ}$ domain structures were observed from PFM images, and their habit planes were identified using electron backscatter diffraction in conjunction with PFM data. By externally applied mechanical stress, needle-like $non-180^{\circ}$ domain patterns were broadened via domain wall motions. This was interpreted via phenomenological approach such that the total energy minimization can be achieved by domain wall motion rather than domain nucleation mainly due to the local gradient energy. Meanwhile, no motion was observed from curvy $180^{\circ}$ domain walls under the mechanical stress, validating that $180^{\circ}$ domain walls are not directly influenced by mechanical stress.

A tumor suppressor, merlin is a member of ERM family proteins. It consists of N-terminal FERM domain, ${\alpha}-helical$ region, and C-terminal domain. Alternative splicing of merlin's mRNA generates two isotypes of merlin. Isotype I, which has exon17 at the C-terminus instead of exon16 in isotype II, is known to have tumor suppressor activity. Like other ERM proteins, the C-terminal domain of merlin isotype I interacts to its FERM domain. That of isotype II, however, was reported not to bind FERM domain despite the large common part of C-terminal domain, which possibly binds FERM domain. Here, we show the binding of FERM domain to both C-terminal domains of merlin's two isotypes by isothermal titration calorimetry. These results support that merlin isotype II also can form a closed conformation or a multimer by intramolecular or intermolecular interactions using their FERM domain and C-terminal domain.

이 연구의 목적은 초·중·고등학교의 교육현장에서 창의성의 영역성이 어떻게 나타나는가를 실증적으로 검증하는 것이다. 연구대상을 전체학생 집단, 고창의성 집단, 저창의성 집단의 3개 집단으로 구분하여 각 집단에서의 영역성을 비교 규명하는 것이다. ‘능력-분화가설’에 기초하여, 4개 영역간의 상관관계, 영역-일반성의 변인과 영역-특수성의 영역간의 상관관계, 그리고 영역-특수성에 대한 영역-일반성의 상대적 예측력을 분석하였다. 연구결과, 연구가설과는 오히려 반대의 결과가 나타났다. 즉, 저창의성 집단에서는 영역-특수성을 지지하였으나, 전체학생과 고창의성 집단에서 영역-일반성과 영역-특수성의 어느 한쪽을 일방적으로 지지하기 어려운 결과가 나타났다. 오히려 영역-일방성과 영역-특수성이 상호 보완 또는 통합되는 영역-상보설이 지지되었다.

The role of domain-specific causal mechanism information and domain-general conditional probability in young children's causal reasoning on physics and psychology was investigated with the participation of 121 3-year-olds and 121 4-year-olds recruited from seven child care centers in Seoul, Kyonggi Province, and Busan. Children watched moving pictures on physical and psychological phenomena, and were asked to choose an appropriate cause and justify their choice. Results showed that young children's causal reasoning differed depending on domain-specific mechanism. In addition, their causal reasoning on physics and psychology differed by the developmental level of causal mechanism. The interaction of domain-specific mechanism and domain-general conditional probability influenced children's causal reasoning : evident conditional probability between domain-appropriate cause and effect helped children make more inferences based on domain-specific causal mechanism.

Living cells are sustained not by individual activities but rather by coordinated summative efforts of different biological functional modules. While recent research works have focused largely on finding individual functional modules, this paper attempts to explore the connections or relationships between different cellular functions through cross-function domain interaction maps. Exploring such a domain interaction map can help understand the underlying inter-function communication mechanisms. To construct a cross-function domain interaction map from existing genome-wide protein-protein interaction datasets, we propose a two-step procedure. First, we infer conserved domain-domain interactions from genome-wide protein-protein interactions of yeast, worm and fly. We then build a cross-function domain interaction map that shows the connections of different functions through various conserved domain interactions. The domain interaction maps reveal that conserved domain-domain interactions can be found in most detected cross-functional relationships and a f9w domains play pivotal roles in these relationships. Another important discovery in the paper is that conserved domains correspond to highly connected protein hubs that connect different functional modules together.

Let D be an integral domain, and let U be a group of units of D. Let $D^*=D-\{0\}$ and ${\Gamma}=D^*/U$ be the commutative cancellative semigroup under aU+bU=abU. We prove that $Cl(D)=Cl({\Gamma})$ and that D is a PvMD (resp., GCD-domain, Mori domain, Krull domain, factorial domain) if and only if ${\Gamma}$ is a PvMS(resp., GCD-semigroup, Mori semigroup, Krull semigroup, factorial semigroup). Let U=U(D) be the group of units of D. We also show that if D is integrally closed, then $D[{\Gamma}]$, the semigroup ring of ${\Gamma}$ over D, is an integrally closed domain with $Cl(D[{\Gamma}])=Cl(D){\oplus}Cl(D)$; hence D is a PvMD (resp., GCD-domain, Krull domain, factorial domain) if and only if $D[{\Gamma}]$ is.
