연구대상판결은, (1) 상속재산분할은 그 성질상 협의의 성립과 동시에 종료하고 그 후에는 그 협의에서 그 채무를 부담한 상속인과 그 채권을 취득한 상속인 간의 채권채무관계가 남을 뿐이라는 점, (2) 협의분할의 법정해제를 인정할 경우 소급효를 갖는 상속재산의 재분할이 불가피하게 되어 법적 안정성이 크게 저해된다는 점을 근거로 하여, 협의분할의 법정해제를 부정하였다. 그러나 (1) 상속재산협의분할은 실질적으로 공동상속인 상호 간의 지분교환 양도 포기에 상당한 처분의 성질을 가진다는 점, (2) 공동상속인 전원에 의한 협의분할의 합의해제에 있어서도 소급효를 갖는 상속재산의 재분할이 불가피함에도 불구하고 합의해제의 유효성을 인정하는 데 아무런 이론(異論)이 없다는 점에서, 협의분할이 실질적으로 공동상속인 간의 부담부증여와 같은 성질을 가지는 경우에는 협의분할에 대한 법정해제도 인정하는 것이 온당하다. 다만, 상속재산분할협의는 공동상속인 전원이 참여해야만 성립되는 계약이므로, 협의분할시 상속인 일방이 부담한 채무의 불이행을 이유로 하는 협의분할의 법정해제도 그 일방을 제외한 다른 공동상속인 전원의 의사표시에 의해서만 가능하다고 보아야 한다.

Let X be a Banach space and Z a closed subspace of a Banach space Y. Denote by Ｌ(X, Y) the space of all bounded linear operators from X to Y and by Ｋ(X, Y) its subspace of compact linear operators. Using Hahn-Banach extension operators corresponding to ideal projections, we prove that if either $X^{**}$ or $Y^{*}$ has the Radon-Nikodym property and Ｋ(X, Y) is an M-ideal (resp. an HB-subspace) in Ｌ(X, Y), then Ｋ(X, Z) is also an M-ideal (resp. HB-subspace) in Ｌ(X, Z). If Ｌ(X, Y) has property SU instead of being an M-ideal in Ｌ(X, Y) in the above, then Ｋ(X, Z) also has property SU in Ｌ(X, Z). If X is a Banach space such that $X^{*}$ has the metric compact approximation property with adjoint operators, then M-ideal (resp. HB-subspace) property of Ｋ(X, Y) in Ｌ(X, Y) is inherited to Ｋ(X, Z) in Ｌ(X, Z).

In this paper we show that Helton class preserves the nilpotent and finite ascent properties. Also, we show some relations on non-transitivity and decomposability between operators and their Helton classes. Finally, we give some applications in the Helton class of weighted shifts.

A module is said to be ${\pi}$-extending provided that every projection invariant submodule is essential in a direct summand of the module. In this article, we focus on the class of modules having the ${\pi}$-extending property by looking at the singularity of quotient submodules. By doing so, we provide counterexamples, using hypersurfaces in projective spaces over complex numbers, to show that being generalized ${\pi}$-extending is not inherited by direct summands. Moreover, it is shown that the direct sums of generalized ${\pi}$-extending modules are generalized ${\pi}$-extending.

SR DEVS 모델링에 의한 객체 상속은 일부 자산에 대한 숨겨진 상속이 가능하다. 부모 객체로부터 넘겨받은 자산에 대해 자식 객체는 넘겨받은 자산의 일부 혹은 전부를 각각의 지정된 함수에 의해 수행할 수도 수행하지 않을 수도 있다. 자산 수행에 대한 숨겨진 상속은 자식 객체가 해당 자산에 대해 자원은 보유하고 있더라도 그것에 대한 수행은 하지 않는 것이다. 상속된 자산은 자식 객체의 자산 수행 전체에 나타나지 않을 수도 있으며, 특정한 시스템 상태에 따라 자산 수행을 할 수 있다. 여기서 자산 수행 전체라 함은 자식 객체가 생성되어 소멸될 때까지의 시간적 요소도 포함된다. 본 논문에서는 부모 객체로부터 상속받은 자산에 대해 숨겨진 상속 결정에 대한 확률 방안을 기술한다. 결정확률 함수에 의해 상속 자산이 숨겨진 상속이 될지 정상 상속이 될지 결정되는 것이다.

In this paper, we construct new classes from the idea of [6, Theorem 2.1] and show that the property of operators belonging to the classes is inherited by certain dilations. And we also prove that the existence of common noncyclic vectors for certain families is equivalent to the existence of infinite dimensional common semi-invariant subspace of operators.

In general, the Least Square Error method is used for signal classification to measure distance in the $l^2$ metric or the $L^2$ metric space. A defect of the Least Square Error method is that it does not classify properly some waveforms, which is due to the property of the Least Square Error method: the global analysis. This paper proposes a new linear operator, the Integra-Normalizer, that removes the problem. The Integra-Normalizer possesses excellent property that measures the degree of relative similarity between signals by expanding the functional space with removing the restriction on the functional space inherited by the Least Square Error method. The Integra-Normalizer shows superiority to the Least Square Error method in measuring the relative similarity among one dimensional waveforms.

In this paper we study the Banach space $L^1$(G) of real valued measurable functions which are integrable with respect to a vector measure G in the sense of D. R. Lewis. First, we investigate conditions for a scalarly integrable function f which guarantee $f{\in}L^1$(G). Next, we give a sufficient condition for a sequence to converge in $L^1$(G). Moreover, for two vector measures F and G with values in the same Banach space, when F can be written as the integral of a function $f{\in}L^1$(G), we show that certain properties of G are inherited to F; for instance, relative compactness or convexity of the range of vector measure. Finally, we give some examples of $L^1$(G) related to the approximation property.

Cultural properties are valuable objects, which have exposed insevere environment and inherited for a long time but we don’t have correct information concerning materials, structure and skill of manufacture. Because the cultural properties have been destroyed by the deterioration elements as like wind, this must be carefully treated for investigation of exhibition and storage. Even if the observation is scientific research, we must not take actual sample from the object for obtaining information concerning the nature materials and skill of manufacture. so it is elementary principle to use non-destructive investigation method as analytical methods for cultural property. This contribution discusses the present condition and problem of X-ray fluorescence acting as a representative non-destructive investigation method and the difference of statistics to be connected with determination and finally explains the intend facts for analysis of data.

In this article, we define a module M to be G^z-extending if and only if for each z-closed submodule X of M there exists a direct summand D of M such that X ∩ D is essential in both X and D. We investigate structural properties of G^z-extending modules and locate the implications between the other extending properties. We deal with decomposition theory as well as ring and module extensions for G^z-extending modules. We obtain that if a ring is right G^z-extending, then so is its essential overring. Also it is shown that the G^z-extending property is inherited by its rational hull. Furthermore it is provided some applications including matrix rings over a right G^z-extending ring.
