Class components in a repository require exact information representation by reason of insufficiency of various visual information through search and extraction. In this paper, we have described syntax-analysis method and viewer facilities about class components. In the components analysis, we extracted class information which consists of class_names, methods, attributes, class inheritance relationship, and graphic information. viewer represents extracted class information and creates a new class. Also, it provides facilities of reuse, insertion, and deletion. Not only Viewer represents class hierarchy diagram, and shows detail information about each class, but also it creates new classes. In this paper, we implemented a Viewer using the components, inheritance, diagram information and process. And we enhanced understanding of programs through viewer, and supported prototype for class creation.

This paper presents a hierarchical structuring method for the multidimensional type inheritance indices (MD-TIXs) that support the processing of XML queries in XML databases. MD-TIX uses a multidimensional index structure for efficiently supporting ancestor-descendant explorations that involve both nested element and type inheritance hierarchies. However, In the case of a long Xpath, the building and maintenance of MD-TIX are very difficult because of index entry construction problem. So, we propose a type inheritance index hierarchy method for solving this difficulty. We first construct base indices that support direct relationship explorations between adjacent two types on a given Xpath, and then, based on these base indices, we construct hierarchically the derived indices that support indirect relationship explorations between any two types of Xpath until constructing one target index for supporting the full Xpath. And we also present an algorithm that efficiently constructs a partial index hierarchy for supporting given a set of sub-pathes explorations.

This paper proposes an algorithm for class hierarchies which can optimize member data and member function. This algorithm considers single/multiple inheritance, static/dynamic binding, overloading/overriding, pure virtual/virtual function, and constructor on the hierarchy of C++ class. We need to eliminate unused function that possesses many component element, because the program uses a limited of function in class hierarchies. Previous works on slicing mainly focused on selecting output data and including the related program statement. It was consists of structured programming language and also centralized on error detection, maintenance, and flexible testing. In this paper, we extend to the object-oriented language, makes a linked-table for objects to raise the efficiency of information management, and proposes necessary algorithm for optimizing system Through this process, we can obtain the simplification of program code and the progress of system performance by eliminating unused member data and member function.

This paper examines the effect of redistributive inheritance tax on income distribution and social welfare. The model used here is the Overlapping-Generations Model consisting of individuals with different bequest motives where the lifetime income distribution in each cohort is determined endogeneously by the dynamic bequest process. It is shown that the introduction of redistributive inheritance tax can improve the vertical equity in the sense that the increase in tax rate reduces the coefficient of variations of intra-cohort income distribution in steady-state. However, it is also shown that, the effect on social welfare, when measured by Benthamite SWF, is uncertain in general. The numerical simulations show that, in spite of its equity-enhancing effect, the tax increase can actually lower the steady-state social welfare within the plausible range of parametric values, through the long-run output effect as well as the deadweight welfare loss incurred by tax distortion. Hence, the problem of equity-efficiency trade-off can arise in this case. However, if both the market interest rate and the elasticity of marginal utility in individual's preference function are sufficiently high, it is shown to be possible that the steady-state social welfare is enhanced by the introduction of inheritance tax.

In a recent study conducted in South Korea, a nation grappling with the implications of an increasingly super-aged society, researchers empirically analyzed the factors influencing seniors' satisfaction with financial institutions' wealth management (WM) services. We surveyed 250 seniors who utilized financial institutions' wealth management services. Independent variables such as product(diversity, profitability, stability), employee(expertise, problem-solving ability, customer orientation), physical evidence, process, inheritance service, and trust service were carefully examined. Employing hierarchical regression analysis, we tested hypotheses within an established research model. The findings revealed that variables like product stability and profitability, employee problem-solving ability, customer orientation, process, inheritance service, and trust service significantly positively affected satisfaction with WM services. In contrast, no substantial association was detected between satisfaction and factors like product diversity, employee expertise, or physical evidence. Among the influential factors, the order of impact was determined to be employee customer orientation, problem-solving ability, trust service, product stability, inheritance service, product profitability, and process. This research provided essential insights into the nuanced preferences and needs of seniors concerning wealth management services. The detailed examination of the subject might also shed light on similar challenges faced in the other aging societies. As the global population continues to age, the implications of this study could reach far beyond the borders of South Korea. By understanding these key determinants of satisfaction, financial institutions worldwide can tailor their wealth management services to better meet the unique demands of the senior population.

In the paper, we describe the query extension techniques for spatiotemporal query functionalities on object-relational DBMS. The spatial objects in real world change the shapes over time. Spatiotemporal databases support to manage a temporal dimension as well as a spatial dimension for history of the objects. The proposed techniques can make conventional object-relational databases to support spatiotemporal databases system by the implementation and inheritance of abstract data types. We define and implement spatial and temporal classes as superclass. And, spatiotemporal classes inherits and extends the classes. The proposed extensions make it easy that conventional database systems not only are transformed into the spatiotemporal database systems, but also do not need to be changed to support spatiotemporal applications.

As a large portal sites are beginning to replace the function of the mass media, new risks began to raise. It remained without being deleted that data written to the internet was a serious privacy problem occurs. The sensitive information was inferred based on the personal data recorded in the past and also another personal information leakage itself. Witch-hunt through the personally identifiable rob has emerged as a serious social problem and damage to the parties not be able to live a normal life. In this paper, we propose the study on the need for a 'right to be forgotten' to delete the personal information relating to on-line through international case studies and activation measures. At the same time, we proposed improvement measures, such as encryption management, ownership inheritance, and blind treatment.

We develop a method to simulate diverse actions for a virtual world consisting of numerous interrelated objects. We focus on how to efficiently model those countless actions rather realistic representation of each action. To this end, those actions are structured into hierarchies according to their characteristic parameters so actions can be efficiently added based on inheritance. The first key issue in this model is how to extract commonality among actions and identify their idiosyncrasy. The second issue is how to reify or substantiate inheritance of the actions. We apply the developed model to the walk actions of quadruped, and their simulated results are shown in articulated figures.
