MicroC/OS-II에서는 우선순위 역전 현상에 대한 해결 기법으로 뮤텍스를 사용한 기본적인 우선순위 상속(Basic Priority Inheritance)을 사용한다. 뮤텍스를 구현하려면 리얼타임 커널이 우선순위가 같은 여러 태스크를 지원해야 한다. 하지만 MicroC/OS-II는 우선순위가 같은 여러 태스크를 지원하지 않는다. 이를 해결하기 위해 MicroC/OS-II는 우선순위 예약을 사용할 수밖에 없었으며 이로 인해 불필요한 메모리공간 및 우선순위 자원을 낭비하게 된다. 본 논문에서는 MicroC/OS-II에서의 불필요한 메모리 낭비와 우선순위 낭비를 줄여, 적은 용량의 메모리를 가지는 임베디드 장비에 효율적으로 운영되도록 제안 하고자 한다.

Background: The author investigated the structural theory of the mind, the origin of psychopathology, the resolving stage of the psychopathology, and nature of the true mind in the human mind. Methods: The author reviewed the "Awakening of Faith in the Mah$\bar{a}$y$\bar{a}$na" by Mamyung and "The Commentary on the Treatise of Awakening Mah$\bar{a}$y$\bar{a}$na Faith" and "Expository Notes on the Treatise of Awakening Mah$\bar{a}$y$\bar{a}$na Faith" by Wonhyo. Results: The author of the Treatise insisted on believing the true mind in the human being. Also in the treatise, $\bar{A}$layavijn$\bar{a}$na explained the harmonized mind of the true mind and the ignorant mind. The ignorant mind as the source of fundamental ignorance, which results in peripheral ignorance arising from the ego in relation with the external world Also, he explains the origin of ignorance and encourages to abandon the deep attachment to ignorance. The developing and resolving stages of ignorance are similar to the developing and resolving stage of psychopathology. Conclusion: The author insists on the psychiatric application of the mind theory in the "Awakening of Faith in the Mah$\bar{a}$y$\bar{a}$na", "The Commentary on the Treatise of Awakening Mah$\bar{a}$y$\bar{a}$na Faith", and "Expository Notes on the Treatise of Awakening Mah$\bar{a}$y$\bar{a}$na Faith" Also, the author encourages deep faith of the true human mind.

Service-oriented computing systems have been issued by their properties of reducing software development time and effort by reusing functional service units. The reusability of services can effectively promote through loose coupling between services. But strong associations of object-oriented systems such as inheritance and aggregation create a rather tight coupling between objects. The component-based systems without inheritance and aggregation create a loose coupling between components. Thus components provide service realization at runtime using the functionality provided by their interfaces. Therefore legacy component-based systems need to have service-oriented computing concept in order to support functional service units efficiently. Also, conventional methods for service-oriented computing system have not suggested the clear classification of service layers, the clear service identification guideline introducing service layers and a service mapping method between serviceces of each layer. Therefore we suggest the service classification and the identification guideline of business view and implementation view introducing layers and propose a mapping between two views. That is, we research service layers, service identification, diversified service sizes and a service mapping method between services of each layer. This can be applied to legacy component-based system to extend to the service-oriented computing system.

Recently the entertainment and sports/advertisement industry have developed rapidly, and the name or identities of celebrities such as entertainers or athletics for the advertisement so that following troubles are occurred continually. Some celebrities actually started a suit for there right of publicity was violated, and won the case. Meanwhile, the right of publicity has become a growing issue in the society. In the States, the right of publicity which controls using one's identity for commercial use, and it is recognized as a right of property separated from the right of privacy. But in Germany, the right of publicity is protected as a human right. On the other hand, in Korea, there is an argument that the mental human right and the right of publicity which has property-characteristic are not separated clearly, and also the attitude of precedent toward the right of publicity is not unified. Especially in Korea, where it is taking the written laws principally, it is not easy to recognize the right of publicity which is a monopoly and exclusion without basis such as any actual laws such as regulation of agreement or any conventional laws. Therefore, as the right protection of celebrities is becoming the social state and there is an agreement with the constituents of the society, now Korea shall progress legislation about the right of publicity, and prepare a legal basis which regulates the remedies for the realization condition, alienation, inheritance, objectives, duration and violation of the right of publicity.

Object-Oriented (OO) methodology to use the concept like encapsulation, inheritance, polymorphism, and message passing demands metrics that are different from structured methodology. There are many studies for OO software metrics such as program complexity or design metrics. But the metrics for the analysis class need to decrease the complexity in the analysis phase so that greatly reduce the effort and the cost of system development. In this paper, we propose new metrics to measure the complexity of analysis classes which draw out in the analysis phase based on Unified Process. By the collaboration complexity, is denoted by CC, we mean the maximum number of the collaborations can be achieved with each of the collaborator and detennine the potential complexity. And the interface complexity, is denoted by IC, shows the difficulty related to understand the interface of collaborators each other. We prove mathematically that the suggested metrics satisfy OO characteristics such as class size and inheritance. And we verify it theoretically for Weyuker' s nine properties. Moreover, we show the computation results for analysis classes of the system which automatically respond to questions of the it's user using the text mining technique. As we compared CC and IC to CBO and WMC, the complexity can be represented by CC and IC more than CBO and WMC. We expect to develop the cost-effective OO software by reviewing the complexity of analysis classes in the first stage of SDLC (Software Development Life Cycle).

The emplacement ages, whole-rock geochemistry and Sr-Nd isotopic compositions of granitoid rocks from Cheongju area, South Korea, were investigated for delineating their petrogenetic link to the Jurassic Daebo granitoid rocks. Zircon crystals were collected from the diorite, biotite granite and acidic dyke samples in a single outcrop. Cross-cutting relationships show that the emplacement of diorite was postdated by the intrusion of biotite granite. Both rocks have been subsequently intruded by acidic dyke. The U-Pb isotopic compositions of zircon from the diorite, biotite granite, and acidic dyke were measured using a SHRIMP-II ion microprobe, yielding the crystallization ages of $174{\pm}2Ma$, $170{\pm}2Ma$, and $170{\pm}5Ma$, respectively, with 95% confidence limits ($t{\sigma}$). The emplacement ages are consistent with those determined from the above relative ages. The major and trace element patterns of the rocks are consistent with those of the Jurassic Daebo granitoid rocks, possibly suggesting a subduction-related I-type granite. The geochemical signature is, however, betrayed by the Sr and Nd isotopic compositions of these rocks. The isotopic signatures suggest that the rocks were produced either by the partial melting of lower-crust or by the mantle-derived magma contaminated by the basement rocks during its ascent and/or emplacement. In addition, the inherited ages of zircons of the rocks (ca. 2.1, 1.8, 0.8 and 0.4 Ga) suggest a possible assimilation with crustal rocks from the Gyeonggi massif and Ogcheon metamorphic belt.

Commonly to design a database system. a conceptual database has to be designed and then it is transformed into a logical database schema prior to building a target database system. This paper proposes a method which transforms a Temporal Entity-Relationship Model(TERM) into a Temporal Object-Oriented Model(TOOM) to build an efficient database schema. I formalize the time concept in view of object versioning and specify the constraints required during transformation procedure. The proposed transformation method contributes to getting the logical temporal data from the conceptual temporal events Without any loss of semantics, Compared to other approaches of supporting various properties, this approach is more general and efficient because it is the semantically seamless transformation method by using the orthogonality of types of objects, semantics of relationships and constraints over roles.

The purpose of this study was to investigate older people's planning for estate distribution by examining the factors associated with their will-holding status. This study used data from the 1994 Assets and Health Dynamics among the Oldest Old (AHEAD) Survey, Wave One. The objectives of this study were (a) to establish profiles of older people who have a written will and to compare their financial portfolios across will-holding status; (b) to identify factors that influence the decision to make a will, and (c) to draw implications for family economists, financial educators, planners, and policy makers. The results suggested that a household's financial resources (i.e., liquid and illiquid assets, housing equity, and household income) positively influence the probability of having a will. Older people who resided in a community property state and who were in poor health were less likely to be will-holders than their counterparts, holding financial resources and other variables constant. Demographic characteristics such as age, education, and race, and behavioral characteristic also were significant determinants of the likelihood of having a will. Volunteer participation and charitable contribution, which are proxies for altruism, increased the likelihood of having a will. The probability of having a will also was higher among those who had life insurance and had gwen inter-vivos gifts of more than $\$5,000$ to their children or grandchildren in the past 10 years. On the other hand, the likelihood of having a will declined with increasing number of biological children. From the findings, implications for financial planners and educators were suggested along with directions for future research.
