The study was aimed at verifying the effectiveness of Book-Coding reading education as a reader activity of older elementary school children at a time when high-dimensional thinking abilities were formed. To this end, 30 fifth-grade children of N Elementary School in N-si, Gyeonggi-do, comprised of 15 students from a reading education program using Book-Coding, and 15 students from a reading comprehension program, and applied the reading education program over a total of 12 sessions. The main results of the study are summarized as follows. First, when the effects of the convergence reading education program using Book-Coding on the logical thinking ability of the students in the upper grades in the elementary school were analyzed, all the six sub-factors of logical thinking ability, that is, conservation logic, proportional logic, variable controlling logic, probabilistic logic, correlational inference logic, and combinational logic, were proved to have statistically more meaningful difference than the group writing a book report. Second, the analysis result of the influence of the convergence reading education program using Book-Coding on the creativity of the students in the upper grades of the elementary school showed that all the 13 elements of curiosity, persistence, effectiveness, independence, adventurousness, openness, knowledge, imagination, originality, sensitivity, fluency, flexibility, and accuracy were statistically meaningfully different compared to the book report group. Third, when it was analyzed how the convergence reading education program using Book-Coding affected the creative personality of the elementary school students, all the six factors of curiosity, task commitment, independence, awareness of risk, and openness of thinking, and aesthetics were found out to have a statistically more meaningful difference than the group that wrote a book report.

본 논문은 베이즈주의가 확률론을 이용해서 제거적 귀납을 정교하게 발전시키고 있다고 주장한다. 이를 위해 본 논문은 두 가지 작업을 진행한다. 하나는 제거적 귀납이 무엇인가 하는것이고 다른 하나는 제거적 귀납이 베이즈주의에 기여하는 바가 무엇인가 하는 것이다. 먼저 본 논문은 제거적 귀납이 참인 가설을 포함하는 가능한 가설들의 총체로부터 경쟁가설들을 연역적 또는 귀납적으로 제거하고 남는 가설을 선택하는 추론형식임을 밝히고, 이 때 베이즈주의는 제거적 귀납을 정교하게 발전시킨 모습이기 때문에 제거적 귀납으로부터 기술적으로 도움 받을 측면은 없다고 주장한다. 그 대신 본 논문은 베이즈주의가 과학방법론으로 발전되는 데에서 직면하는 여러 가지 문제점을 해결하는 방법에 대해 제거적 귀납으로부터 조언을 얻을 수 있다고 주장한다. 이와 같은 논의를 통해 본 논문은 베이즈주의와 제거적 귀납주의의 결합은 유용한 과학방법론을 만들 수 있을 것으로 전망한다.

공리적 설계는 미국 매사추세츠 공과대학의 서남표 교수에 의해 창출되고 보급되어 온 설계이론이다. 그러나 좀 더 정확히 말한다면 설계이론 이라기보다는 일반적인 공학적 과정에 적용할 수 있는 원리를 포함하는 설계프레임워크라 할 수 있다. 기계공학에서의 역학과 같이 설계를 하기 위해서는 과학적인 기본원리에 따라 설계해야 한다는 것이다. 그러므로 공리적 설계는 설계과정에서 설계자에게 과학적 원리를 제공하여 설계자가 이성적이고 논리적으로 설계를 진행할 수 있도록 하여, 시행착오를 줄이며, 좀 더 창조적이고 최상의 설계를 선택할 수 있도록 도움을 주는 것이다.(중략)

The purpose of this study was to discover differences between mathematically gifted students (MGS) and non-gifted students (NGS) when making probability judgments. For this purpose, the following research questions were selected: 1. How do MGS differ from NGS when making probability judgments(answer correctness, answer confidence)? 2. When tackling probability problems, what effect do differences in probability judgment factors have? To solve these research questions, this study employed a survey and interview type investigation. A probability test program was developed to investigate the first research question, and the second research question was addressed by interviews regarding the Program. Analysis of collected data revealed the following results. First, both MGS and NGS justified their answers using six probability judgment factors: mathematical knowledge, use of logical reasoning, experience, phenomenon of chance, intuition, and problem understanding ability. Second, MGS produced more correct answers than NGS, and MGS also had higher confidence that answers were right. Third, in case of MGS, mathematical knowledge and logical reasoning usage were the main factors of probability judgment, but the main factors for NGS were use of logical reasoning, phenomenon of chance and intuition. From findings the following conclusions were obtained. First, MGS employ different factors from NGS when making probability judgments. This suggests that MGS may be more intellectual than NGS, because MGS could easily adopt probability subject matter, something not learnt until later in school, into their mathematical schemata. Second, probability learning could be taught earlier than the current elementary curriculum requires. Lastly, NGS need reassurance from educators that they can understand and accumulate mathematical reasoning.

This study is a numerical representative modelling analysis for applying the process that unravels networks between cells in genetics to WWW of informatics. Using the probabilistic graphical model, the insight from the data describing biological networks is used for making a probabilistic function. Rather than a complex network of cells, we reconstruct a simple lower-stage model and show a genetic representation level from the genetic based network logic. We made probabilistic graphical models from genetic data and extends them to genetic representation data in the method of network modelling in informatics.

기술거래 시장의 활성화에 대한 연구개발서비스 분야 종사자들의 관심이 높아지고 있으며, 특히 공공 및 민간 분야의 휴면 기술(특허)에 대한 이전 거래를 통해 불필요한 특허유지 비용을 줄이고 부가적인 기술료 창출 효과를 거둘 수 있다. 본 연구에서는 현재까지 기술이전(거래), 현물출자, 기술금융(융자, 담보대출) 등 다양한 목적으로 실무에서 활용되어 온 기술가치평가 모형의 한계점을 고민해 보고, 이에 대한 개선방안으로서 몬테카를로 최소자승법 기반의 확률론적 가치평가 모형을 제시한다. 기존의 가치평가 모형은 평가산출을 위한 입력변수의 확정적 값들에 기반하여 가치액이 산출되었으나, 대표적 기법인 현금흐름 할인법이나 로열티공제법의 경우 미래의 수익예상기간, 예상매출액 등에서는 불확실성(uncertainty)가 내재되어 있다. 따라서 특정 분포(distribution)에 대한 확률론적 가능성을 가정하고 이에 대한 수학적 최적화 논리로부터 몬테카를로 최소자승 관게에 의한 변수결정 및 가치평가액 산정을 할 수 있는 평가모듈을 개발한다. 향후 연구에서는 기 평가된 사례결과를 딥러닝(deep learning) 방식으로 학습하여, 발생가능성 높은 각 변수값의 범위들을 산출하고 이로부터 기술가치 범위를 추론하는 시스템을 개발하는 것도 가능할 것으로 기대된다.

뜻이 느낌만으로 충분한가를 살펴본다. 느낌이 보거나 들을 수 없다는 특성을 감안하여 보거나 들을 수 있는 또 다른 언어로 표현된 것에 의하여 고찰하는 것이 더 정확하다고 보아서 변역에 의하여 고찰하는 방법을 택한다. 한 표현p에 대한 느낌을 인지자i의 주관적인 작용에 따라 다르다는 것은 분명하나 그 다름을 식별하는 어려움이 있어서 변역에 의한다. 성급히 보편적인 뜻이 없다고는 못하나 실제로는 합의된 뜻이 사용된다. 합의는 절대적이지 않아서 절대적인 분식성과 개연성의 이분법을 받아들이지 않는다. 또 이러한 관점에서 양상논리의 삼분법보다는 다치논리가 더 엄밀하다고 본다. 그래서 함의된 뜻에서의 합의는 이분법이나 삼분법에 의한 합의가 아닌 확률적인 정도에 의존한다.

In this paper, we proposed the mechanism for the buffer allocation and a cell scheduling method with logical separation a single buffer in the ATm switch, and analyzed the cell loss probability and the delay of each trafic (CBR/VBR/ABR) based on the weighted value and the dynamic cell service scheduling algorithm. The proposed switch buffering system classifies composite trafics incoming to the switch, according to the characteristic of traffic, then stores them in the logically separated buffers, and adopts the round-robin service with weighted value in order to transmit cells in buffers though one output port. We analyzed 4 cell service scheduling algorithms with dynamic round-robinfor each logically separated service line of a single buffer, in which buffers have the respective weighted values and 3 classes on mixed traffic which characteristized by traffic descriptor. In simulation, using SIMCRIPT II.5., we model the VBR and the ABR traffics as ON/OFF processes, and the CBR traffic as a Poisson processes. As the results of analysis according to the proposed buffer management mechanism and cell service algorithm, we have found that the required QoS of each VC can be quaranteed depends on a scale of weighted values allocated to buffers that changed the weighted values, and cell scheduling algorithm.
