최근 각종 사물인터넷 제품이 시장에 출시되면서 관련 업체들은 시장을 선점을 위해 표준화 플랫폼 분야에서 경쟁을 벌이고 있다. 국내 이동통신 3사는 가정용 사물인터넷 서비스를 출시하면서 경쟁을 벌이고 있다. 대표적 출시된 서비스는 스마트홈 관련 분야이다. 그러나 이동통신 기반 사물인터넷 서비스는 초기 단계에 머물고 있으며, 지속적으로 다양한 서비스가 출시될 것으로 예상된다. 이러한 시점에 이미 출시된 서비스를 중심으로 사물인터넷 서비스에 대한 선호도 분석을 기획하게 되었다. AHP(analytic hierarchy process) 분석기법을 적용하기 위해 1단계 요인으로는 안전, 보안, 건강, 지능 그리고 가전으로 설계하였다. 또한 2단계 요인으로는 개념모델에서 제시된 18개 세부 서비스로 조직하였다. 따라서 분석결과를 바탕으로 연구의 한계와 이론적 실무적 시사점을 제시하고자 한다.

This study attempts to clarify the relationship between mother;s child-rearing practices and children's critical thinking abilities. More specifically this study wants to answer the questions: (a) Is there any relationship between mother's child-rearing practices and children's critical thinking abilities? (b) What dimensions of child-rearing practices are more important for children's critical thinking abilities? (c) Does the developmental process of children's critical thinking abilities show any difference according to the mother's child-rearing practices? This study is based on the conceptual model of child-rearing practices from the cognitive disciplinary viewpoint proposed by Lee et al.(1973). They polarized the child-rearing practices into the“mediated”types. These types were specified along seven dimensions of child-rearing. In general terms, the two types refer to the degree to which mother resorts to the description of concrete and immediate phenomena and immediate expression of momentary impulses, and positively reinforces such behaviors of her children. Two kinds of data were collected from 60 primary school boys and girls, and their mothers. A child-rearing practices questionnaire with 28 items was sent to the mothers. And the children were administered a critical thinking abilities test containing measures of 4 dimensions from the Ahn's Critical Thinking Measurement Technique. The major findings are those (a) the children of mothers who reported to have used more“mediated”types of child-rearing show relatively higher level of critical thinking abilities than their counterparts; (b) of the seven dimensions of child-rearing practices, the most significant are“mode of description”,“rationality-orientation”and“reward and punishment”; and (c) the“mediated”type of child-rearing practices tends to facilitate critical thinking abilities development. In conclusion, it is believed that a further refinement of this study will contribute to the development of child-rearing training program for mothers.

The Korea Atomic Energy Research Institute has developed an advanced fast reactor concept, KALIMER-600, which satisfies the Generation IV reactor design goals of sustainability, economics, safety, and proliferation resistance. The concept enables an efficient utilization of uranium resources and a reduction of the radioactive waste. The core design has been developed with a strong emphasis on proliferation resistance by adopting a single enrichment fuel without blanket assemblies. In addition, a passive residual heat removal system, shortened intermediate heat-transport system piping and seismic isolation have been realized in the reactor system design as enhancements to its safety and economics. The inherent safety characteristics of the KALIMER-600 design have been confirmed by a safety analysis of its bounding events. Research on important thermal-hydraulic phenomena and sensing technologies were performed to support the design study. The integrity of the reactor head against creep fatigue was confirmed using a CFD method, and a model for density-wave instability in a helical-coiled steam generator was developed. Gas entrainment on an agitating pool surface was investigated and an experimental correlation on a critical entrainment condition was obtained. An experimental study on sodium-water reactions was also performed to validate the developed SELPSTA code, which predicts the data accurately. An acoustic leak detection method utilizing a neural network and signal processing units were developed and applied successfully for the detection of a signal up to a noise level of -20 dB. Waveguide sensor visualization technology is being developed to inspect the reactor internals and fuel subassemblies. These research and developmental efforts contribute significantly to enhance the safety, economics, and efficiency of the KALIMER-600 design concept.

인공지능, 시맨틱 웹의 분야에서 지식을 표현하고 의미적으로 연결하기 위해 온톨로지가 연구되어 왔다. 그러나 온톨로지는 정의하는 사람의 의도와 지식 수준에 따라 다양하게 표현되고 정의될 수 있다. 이는 동일한 개념을 서로 다르게 표현하는 이질성 문제를 야기한다. 이 논문에서는 이러한 문제를 해결하기 위하여 XMDR에 기반한 온톨로지 생성 시스템인 XOB(XMDR-based Ontology Builder)를 소개한다. XOB는 XMDR에서 정의한 클래스 및 클래스 간의 관계성 등을 재사용하여 온톨로지를 생성함으로써 생성된 온톨로지 간 의미 이질성 문제를 해결 또는 최소화 할 수 있다. 이 논문에서는 제안 시스템인 XOB의 개념 모델 및 전체적인 구조를 소개한다. 또한 XMDR에 등록된 개념들을 이용하여 온톨로지 생성 시 요구되는 프로세스, 알고리즘 및 온톨로지 생성 규칙 등을 정의한다. 제안 시스템은 기존 방법에 비해 높은 표준화를 제공하며 이는 일관성 있는 개념의 활용, 용이한 의미 교환 등의 장점을 제공한다. 따라서 XOB는 고품질의 온톨로지 생성을 가능하게 하며 온톨로지 통합 및 시스템 개발을 위한 비용을 감소시킨다.

In this paper, simulation tests were conducted with similar materials to study the distribution of residual voids in longwall goaf. Short-time step loading was used to simulate the obvious deformation period in the later stage of arch breeding. Long-time constant loading was used to simulate the rheological stage of the arch forming. The results show that the irregular caving zone is the key area of old goaf for the subsidence control. The evolution process of the stress arch and fracture arch in stope can be divided into two stages: arch breeding stage and arch forming stage. In the arch breeding stage, broken rocks are initially caved and accumulated in the goaf, followed by the step deformation. Arch forming stage is the rheological deformation period of broken rocks. In addition, under the certain loads, the broken rock mass undergoes single sliding deformation and composite crushing deformation. The void of broken rock mass decreases gradually in short-time step loading stage. Under the water lubrication, a secondary sliding deformation occurs, leading to the acceleration of the broken rock mass deformation. Based on above research, the concept of equivalent height of residual voids was proposed, and whose calculation equations were developed. Finally, the conceptual model was verified by the field measurement data.

There have been numerous studies in Korea and other countries of which the major hypotheses are identifying and dearibing the conditions under which the value of children has been formed. The present study proposes to view the formation of the value of children as a correlate of family's consumption-saving and work4eisure behavior pattern. The objectives of the proposed study are to identify the socio-economic and demographic factors determining the family's consumption-saving and work-leisure behavior pattern and to analyse the relationship between the value of children and this behavior pattern. The conceptual framwork of the analysis is that an individual family's socio-economic and demographic factors influence and shape the consumption-saving and work-leisure behaviors and these behaviors in turn influence and reflect the correlates and proximate determinants of the family'sfertility. In this paper, regression model is used to analyse the hypothesized relationship among the various variables. The regression methods used are first and second stage multiple regressions. In addition, MONOVA has been used to show the interactions. Data used are collected from the government publicactions. The major findings from this study are as follows: As the living Standard improves, n individual family's consumption of necessities and its working hours decline, while savings and leisure activities increase. The phenomena result in the fertility reduction as can be seen in the more developed conntries. Child-bearing and rearing activities are found to be the important component to determine the condumption-saving and work-leisure activies. The married women's labor participation, and the investment in education and health are also found to be the factors reducing fertility rate.

This article examines the accessibility and usability of library websites to students with visual and physical disabilities in public universities in Kenya. The study used survey research design and adopted a mixed methods approach. Data were gathered using survey questionnaire, focus group discussions, structured interviews, and observation. The study population consisted of six public universities that had a longstanding tradition of enrolling students with disabilities. Census was used to obtain a study sample comprising of students with visual disabilities (86), students with physical disabilities (91), University Librarians (6), Personnel from Disability Mainstreaming departments (6), Systems Librarians (6) and Library Personnel who provided information services to students with disabilities (133). The Social Model of Disability and IFLA Access to Libraries for Persons with Disabilities checklist were used as conceptual and theoretical framework in the study. Study results revealed that all the libraries had library websites. However, the websites did not have disability services page or information specific to individuals with disabilities. Also a section of students with disabilities lacked awareness of the existence of library websites and e-resources available through them. Additionally, the website design posed various access challenges. The study concluded that people with disabilities were excluded from access and use of library websites in public universities. The authors recommended that library websites must contain disability services page containing information specific to persons with disabilities. Moreover, libraries should evaluate their websites to ensure compliance with W3C requirements for web content accessibility. Additionally, libraries should develop disability policy to provide guidance on provision of information services to persons with disabilities.
