본 연구의 목적은 폴라니의 개인적 지식을 중심으로 과학지식의 객관성을 고찰하고, 이의 과학교육적 함의를 논의하는 것이다. 따라서 이론적 연구이며, 주로 문헌자료에 의존하였다. 현대 인식론은 지식의 객관성과 상대성에 대한 견해가 혼재해 있으며, 특히 과학교육의 문제를 해결하기 위해서는 지식의 객관성에 대한 재해석이 필요하다. 이에 과학지식의 객관성에 대한 과학철학자들의 견해를 살펴보고, 객관성을 주관성과 관련시켜 지식의 성격을 이해한 칸트, 왕양명, 키에르케고르의 사상을 교육과 관련지어 간단히 고찰하였다. 나아가 폴라니의 인식론을 중심으로 과학지식에의 개인적 관여 및 공동체적 성격을 살펴보았다. 그리고 개인적 지식에서 시사하는 과학교육적 함의를 논의하면서, 과학교육에 인간의 목소리가 회복되며, 지적 열정이 살아있도록, 과학자의 삶을 재연하는 과학교사의 필요성을 논의하였다.

문화콘텐츠 생산과 소비 환경의 변화에 따라 문화의 전파와 수용, 그리고 매개의 측면에서 1인 미디어가 가지는 디지털 문화매개자의 의미를 확인하고자, 본 연구는 국내에서 인기 있는 유튜브 채널 <영국남자(Korean Englishman)>를 디지털 문화매개자의 특성 요인('문화매개 형식', '문화매개 전달방식', '문화매개 언어특징', 문화매개 평가기준')을 기준으로 분석하였다. 최근 2년 동안의 누적 조회수 기준으로 해당 채널의 상위 50개 동영상의 소개글, 내용, 콘텐츠 이용자들의 댓글을 분석한 결과, 자유로운 주제와 적절한 표현방식(문화매개 형식), 다양한 효과를 적용한 멀티미디어 형태의 전달(문화매개 전달방식), 일상적 언어와 인터넷 용어 및 다국어 이용(문화매개 언어특징), 진정성 있는 콘텐츠 및 콘텐츠 이용자와의 상호작용을 통한 인기 및 선호 증대(문화매개 평가기준)를 통해서 디지털 문화매개자로서의 1인 미디어 역할을 확인할 수 있었다.

디지털 미디어 환경이 도래하면서 정보의 유통방식이 변화되었고, 이에 따라 인터넷을 통해 유통되는 개인정보를 보호하기 위해 '잊혀질 권리'를 법제화할 필요성이 점점 커지고 있다. 하지만 개인정보 보호를 지나치게 강조할 경우 인터넷산업의 발전이 저해되고, 언론자유나 알권리를 비롯한 헌법적 권리를 침해할 우려가 있다. 따라서 잊혀질 권리의 적용 범위를 보다 명확하게 규정할 필요가 있다. 첫째, 개인정보에 대한 권리는 개인정보자기결정권과 사회적 인격상에 관한 자기결정권으로 구분된다. 전자의 경우에는 잊혀질 권리가 적용되지만 후자의 경우에는 개인정보의 보호가치와 활용가치를 비교해서 판단해야 한다. 둘째, 디지털 미디어 환경에서는 과거의 언론보도가 인터넷을 통해 반복적으로 유통되면서 새로운 피해를 낳고 있다. 하지만 과거의 언론보도는 일정한 시간이 지나면 일종의 역사적 기록물이 되기 때문에 잊혀질 권리를 그대로 적용할 수는 없다. 따라서 디지털 미디어 환경에 적합한 새로운 방안을 모색해야 한다.

This paper describes a research work of developing a computer-aided design and manufacturing of irregular shaped sheet metal product for blanking or piercing and bending operations. An approach to the system is based on the knowledge-based rules. Knowledge for the system is formulated from plasticity theories experimental results and the empirical knowledge of field experts, This system has been written in AutoLISp on the AutoCAD and in customer tool kit on the SmartCAM with a personal computer and is composed of nine modules which are input and shape treatment, flat pattern-layout, pro-processor module. Based on the knowledge-based rules, the system is designed by considering several factors, such as material and thickness of product complexities of blank geometry and punch profile sheet metal to give flat pattern and automatically account for the adjustment of bending allowances to match tooling requirements by checking dimensions and generating NC data automatically according to drawings of die-layout module. Results carried out in each module will provide efficiencies to the designer and the manufacturer of blanking or piercing and bending die in this field.

In this paper, we consider a resource allocation scheme for millimeter wave-based wireless personal area networks using directional antennas. This scheme involves scheduling the reservation period of medium access control for IEEE 802.15.3c. Objective functions are considered to minimize the average delay and maximize throughput; and two scheduling algorithms-namely, MInMax concurrent transmission and MAxMin concurrent transmission-are proposed to provide a suboptimal solution to each objective function. These are based on an exclusive region and two decision rules that determine the length of reservation times and the transmission order of groups. Each group consists of flows that are concurrently transmittable via spatial reuse. The algorithms appropriately apply two decision rules according to their objectives. A real video trace is used for the numerical results, which show that the proposed algorithms satisfy their objectives. They outperform other schemes on a range of measures, showing the effect of using a directional antenna. The proposed scheme efficiently supports variable bit rate traffic during the reservation period, reducing resource waste.

This paper describes a research work of developing computer-aided design of a product with bending and piercing for progressive working. An approach to the system for progressive working is based on the knowledge-based rules. Knowledge for the system is formulated from plasticity theories, experimental results and the empirical knowledge of field experts. The system has been written in Auto-LISP on the Auto-CAD with a personal computer and is composed of four main modules, which are input and shape treatment, flat pattern layout, strip layout, and die layout modules. The system is designed by considering several factors, such as bending sequences by fuzzy set theory, complexities of blank geometry, punch profiles, and the availability of a press equipment. Strip layout drawing generated in the strip layout module is presented in 3-D graphic forms, including bending sequences and piercing processes with punch profiles divided into for external area. The die layout module carries out die design for each process obtained from the results of the strip layout. Results obtained using the modules enable the manufacturer for progressive working of electric products to be more efficient in this field.

Objectives : In studying East Asia's medical classics, what must first be done before evaluating the validities of clinical grounds is the discernment of the techniques that are based on universal principles from the statements that arise from individual experience. The purpose of this paper is to discover a method of discerning the statements of individual experiences and the descriptions of universal principles. Ingredients and Methods : The paper investigates how each individual clinical experience was introduced in ancient medical classics such as Huangdineijing, Nanjing, Shanghanlun, Jinkuiyaolue, and Maijing, in the books that belong to Yian such as Canggongliechuan, Linzhengzhinanyian, Gujinyianan, and Xumingyileian, and in Korean ancient medical texts such as Eonhae-gugeubbang and Gugeubganibang-eonhae. Results : Books of precriptions and scriptures of medicine were found to include individual experiences. Furthermore, this paper's effort has revealed that the evaluation of the quality of a testimony in an ancient book must be preceded by discerning whether the said testimony is a mere personal testimony or a testimony based on the universal law of causality. Conclusions : Before conducting a clinical research of a precription contained in an East Asian medical classic, the text should first be evaluated to determine whether the prescription in question derives from clinical tests or not.

SmartThings is one of the most popular open platforms for home automation IoT solutions that allows users to create their own applications called SmartApps for personal use or for public distribution. The nature of openness demands high standards on the quality of SmartApps, but there have been few studies that have evaluated this thoroughly yet. As part of software quality practice, code reviews are responsible for detecting violations of coding standards and ensuring that best practices are followed. The purpose of this research is to propose systematically designed quality metrics under the well-known Goal/Question/Metric methodology and to evaluate the quality of SmartApps through automatic code reviews using a static analysis. We first organize our static analysis rules by following the GQM methodology, and then we apply the rules to real-world SmartApps to analyze and evaluate them. A study of 105 officially published and 74 community-created real-world SmartApps found a high ratio of violations in both types of SmartApps, and of all violations, security violations were most common. Our static analysis tool can effectively inspect reliability, maintainability, and security violations. The results of the automatic code review indicate the common violations among SmartApps.
