Many enterprises make use of 'mecenat action' for positive image ensuring to company and harmony within organization members. Also, at the same time the research has continued estimating of efficiency about that area. but that estimations get accomplished inclusive and abstractive, and then estimation of significant effect isn't sufficient. In this study we consider that many enterprises practice culture and art education program, and related that analyze the estimation of effect in 'mecenat action'. Stand on this analysis we attempts to extract factor, having representation character with making standard for estimation of education effect. That is a implication that relation education programs are prepared many enterprises, In future study, we will need to make standard and select methods about effect estimation, add measurable index that reliability can increase.

It is very important to understand system behaviors in collective pattern for each knowledge domain. However, there are structural limitations to represent collective behaviors because of the size of system components and the complexity of their interactions, causing the state explosion problem. Further composition with other systems is mostly impractical because of exponential growth of their size and complexity. This paper presents a practical method to model the collective behaviors, based on a new concept of domain engineering: behavior ontology. Firstly, the ontology defines each collective behavior of a system from active ontology. Secondly, the behaviors are formed in a quantifiably abstract lattice, called common regular expression. Thirdly, a lattice can be composed with other lattices based on quantifiably common elements. The method can be one of the most innovative approaches in representing system behaviors in collective pattern, as well as in minimization of system states to reduce system complexity. For implementation, a prototype tool, called PRISM, has been developed on ADOxx Meta-Modelling Platform.

This study aims to extend fundamental categories from Clause 11, "facet analysis" in International Standards for thesaurus(ISO 25964-1) by analyzing fundamental categories of Clause 11 and concept and their scope in a thesaurus of Clause 5. For to do this, the fundamental categories were established by adjusting partially and adding mental entities explicitly referencing the highest concepts(YAMATO which is the upper ontology of Mizoguchi, and ISO 2788) and existing fundamental categories(PMEST, FRBR group 3 entities, 13 categories in CRG). Also, established fundamental categories were reorganized and structured based on concreteness/abstraction of PMEST in Ranganathan and independence/dependence of YAMATO in Mizoguchi. And the upper categories were divided into independent and dependent entities. Under these entities 28 criteria are included in the independent ones and 2 criteria in the dependent ones. In the further study, the result of this study can be expected to reuse and refer as controlled vocabulary in the field like classification, taxonomies and thesauri where expected to utilize fundamental categories and as the high-level concept when constructing an ontology for information retrieval.

Many countries design and implement informatics curriculum based on core competencies to respond to the demands of development and reform in rapidly changing times. In this paper, we developed the core competencies framework of elementary information education by comparing and analyzing the core competencies and suggested the direction of the composition of elementary informatics subjects. We found that social-emotional skills, communication, creativity, responsibility, culture and ethics, problem-solving, collaboration and abstract competencies overlapped among the capabilities presented by each country and institution, and computational thinking and information technology utilization skills in Korea. Therefore, we proposed to reflect the core competencies of the framework in the elementary informatics curriculum. Moreover, we also suggested enhancing problem-solving skills, strengthening social responsibility and cultivating convergent skills to organize the curriculum. We hope that this thesis will expand the necessity of organizing an elementary information curriculum that reflects core competencies in the 2022 revised curriculum.

In this parer, we propose a hardware abstraction architecture(HAA) for low cost flash memories that can be applicable to wireless sensor nodes. The proposed HAA consists of three layers. The three layers are 1) HHL(Hardware Interlace Layer), HAL(Hardware Adaption Layer), and HPL(Hardware Presentation Layer), where HIL provides a platform independent interlace to applications of upper layers, HAL performs hardware resource management, program status control, and generation of logical instructions as main core of the HAA, and HPL initializes hardware and communicates data between MCU and flash memory. We implemented our HAA on AT45DB flash memory, and the HAA used 4,384 bytes program memory and 195 bytes data memory respectively. Since the proposed HAA is composed of well defined three layers and shows a low utilization of memory, it can provides a high efficiency in terms of flexibility, scalability, and re-usability, and thus the HAA is well suited for wireless sensor nodes.

최근 사회의 다변화, 고령화 및 소비자의 다양한 욕구 증대 등으로 인하여 세분화된 소비계층을 겨냥한 다양한 신제품들이 출시, 판매되고 있는 반면, 일반 백색시유를 제외하고는 제품의 라이프사이클이 크게 줄어드는 경향을 보이고 있다. 건강기능식품 시대의 도래와 함께 첨단 기능성 소재들이 속속 등장하고 있으며, 유가공업계도 이들 소재를 응용한 연구개발과 공정개선을 통한 신제품 출시에 박차를 가하고 있다. 그러나 음용유 시장에서 절대적인 비중을 차지하고 있는 시유부문은 저출산율과 수입개방 등의 악재로 인하여 점차적인 감소 추세에 접어들고 있다. 따라서 국내 유가공업체는 원유소비 증대와 유제품 경쟁력을 확보하기 위해 유제품의 다양화, 고급화를 위한 기술개발 및 유제품의 적극적인 홍보 등의 전략이 필수적이다. 이를 위해서는 종래 단순가공에 의한 유제품 생산에서 탈피하여 새로운 공정 개발, 신물질 탐색 등으로 생산비 절감, 수율 증대, 다양한 형태의 유제품 개발, 그리고 기능성 소재의 탐색 등 건강 지향적 기능성 식품 개발에 노력을 해야 할 것이며 국공립 및 사립대학교 및 정부 출연기관과 일반 유업체의 공동과제 실시 확대로 기능성 식품에 대한인식제고가 필요할 것이다. 또한, TV 매체를 통한 홍보, 우유의 교과서 반영, 자조금 활성화 등으로 어릴 때부터 우유 먹는 습관을 형성하여 시유 소비기반 확대를 도모해야 할 것임과 아울러 교육당국과 협력하여 학생과 영양교사를 대상으로 한 우유에 대한 체계적인 교육프로그램 실시 및 중 ·고등학교 급식화대 추진 등 관련 기관과의 협력체계 구축을 통한 낙농진흥활동을 전개하여야 한다.유아의 창의성수준을 더 높게 평가하였다. 그러나 아버지와 교사간 평가의 상관은 유의하지 않았는데 이는 아버지의 평가수준이 매우 객관적인 것은 아님을 시사한다. 셋째, 창의적인 유아와 일반 유아 아버지 양육태도에서는 유의한 차이를 보였는데 특히 애정-적대요인과 자율-통제요인에서 창의적인 유아와 일반 유아간의 차이가 있는 것으로 나타났다. 넷째, 유아의 창의성과 아버지 양육태도간의 상관관계분석결과 애정적 양육태도와 유창성, 독창성간의 상관이 유의하였다. 집단별 분석시 창의적인 유아를 둔 아버지의 양육태도와 유아의 창의성간에는 상관이 없는 것으로 나타났고, 일반 유아의 아버지 양육태도와 유아의 창의성간의 상관에서는 아버지 양육태도의 성취-비성취 요인에서와 창의성제목의 추상성요인에서 상관이 있는 것으로 나타났다. 따라서 창의성이 높은 아동의 아버지의 양육태도는 일반 유아의 아버지와 보다 더 애정적이며 자율성이 높지만 창의성이 높은 아동의 집단내에서 창의성에 특별한 영향을 더 미치는 아버지의 양육방식은 발견되지 않았다. 반면 일반 유아의 경우 아버지의 성취지향성이 낮을 때 자녀의 창의성을 향상시킬 수 있는 것으로 나타났다. 이상에서 자녀의 창의성을 향상시키는 중요한 양육차원은 애정성이나 비성취지향성으로 나타나고 있어 정서적인 측면의 지원인 것으로 밝혀졌다.징에서 나타나는 AD-SR맥락의 반성적 탐구가 자주 나타났다. 반성적 탐구 척도 두 그룹을 비교 했을 때 CON 상호작용의 특징이 낮게 나타나는 N그룹이 양적으로 그리고 내용적으로 더 의미 있는 반성적 탐구를 했다용을 지원하는 홈페이지를 만들어 자료 제공 사이트에 대한 메타

This study analyzed the relationships between expenditures on transportation and those on communications, using consumer expenditure data from the U.S. for the 19 years 1984-2002. We first identified 12 categories of goods for transportation and communications, and then applied the linear approximate Almost Ideal Demand System(LA/AIDS) method for estimating consumer demand functions based on aggregating the categories to five (public transportation, personal vehicle capital, personal vehicle operation, electronic communications media, and print communications media) due to the small sample size. Expenditure and price elasticities were also calculated at mean values of expenditure shares. The results indicate that transportation and communications categories have both substitutive(e.g. public transportation and electronic communications media) and complementary(e.g. private vehicle capital and electronic communications media) relationships. Additionally, expenditures in the transportation categories are generally more income-elastic than those in communications.

Recent development and penetrating expansion in ICT(Information and Communication Technology) has brought considerable improvements in transportation services. However, there is a controversial debate whether transportation and communications behave as substitutes or as complements to one another. On this subject, recent studies considered those two industries as services, but transportation and communications are broadly put for intermediary goods into other industries. Hence, it is essential to examine this issue from understanding their relationships to each other with respect to manufacturing and services. In this study, input-output tables of benchmark years from 1980 to 2005 have been analysed to explore the relationships between transportation and communications using Spearman's correlation analysis. The results show that both industries had complementary roles over the period, but, to some extent, changed into substitution roles in some categories.

Recently mobile broadcast standards that have IP layer between transport layer and service layer such as DVB-IPDC, OMA-BCAST have been commercialized. Specially, IP abstract layer of OMA-BCAST makes it possible to interface diverse transport layers. Service guide, that is important for user interface, of these mobile broadcast standards has complex structure and heterogeneous schema. ESG schema is not interoperable, therefore terminals should have various implementations of service layer to support more than one service layer at a time. In this paper, not only for enabling interoperability of DVB-IPDC and OMA-BCAST but for supporting basic scenarios of mobile broadcast, simple ESG schema was developed. This new schema can be used as an independent ESG schema, especially for the integrated mobile broadcast middleware environment.

Real-time embedded systems should accommodate many kinds of hardware platforms and resource management policies that vary depending on their operating environments and purposes. It is not an easy job to adapt a multitasking kernel to new system services and hardware platforms, as the kernel must strictly satisfy constraints on its size and performance. This paper describes the design and implementation of an object-oriented multitasking framework that can be reused for implementing microprocessor-based real-time embedded multitasking kernels, In this kernel framework, those parts that can vary depending on hardware platforms and system resource management policies are separated into the hot spots and encapsulated by abstract classes. Our framework thus can be effectively used to implement microprocessor-based real-time embedded kernels that demand high portability and adaptability.
