홍지호·여영서는 "'부당한 연역 논증'은 형용모순인가?"라는 논문에서 연역 논증과 귀납 논증을 구분하는 기준으로 실현 기준이 아닌 의도 기준을 지지한다. 이 논문은 그들의 주장을 비판하는 것이 목표이다. 나는 그들의 주장이 논증 재구성과 논증 분류[평가]를 헷갈리고 있으며, 의도 기준의 난점을 해명하면서 실현 기준을 들여오고 있다고 주장한다. 그들을 비롯한 대부분의 논리학자들은 논증을 연역, 귀납, 그리고 나쁜 논증으로 나눈다. 나는 연역과 귀납으로 나누어야 한다고 주장한다. 마지막으로 논리 교육에서는 연역과 귀납의 구분을 굳이 가르칠 필요가 없다고 주장한다.

연역 논증과 귀납 논증을 구분하는 실현 기준에 따르면, 전제와 결론 사이에 실현된 뒷받침 관계가 필연성일 경우에만 연역 논증이다. 이 경우 '부당한 연역 논증'은 형용모순을 저지르는 표현이 된다. 이와 달리 전제와 결론 사이에 의도된 뒷받침 관계를 구분 기준으로 삼는 것은 의도 기준인데, 이에 따르면 '부당한 연역 논증'은 형용모순이 아니다. 우리는 의도 기준을 옹호하는데, 실현 기준은 생략 논증을 연역 논증이나 귀납 논증 중 한 쪽으로 분류하기 위해서는 의도를 참조해야 한다는 난점, 또 나쁜 논증과 논증이 아닌 명제들의 집합을 구분하지 못한다는 난점을 지니기 때문이다. 의도 기준 역시 논증 제시 의도를 파악하기 어려운 경우가 있지만, 그것은 자비의 원리에 호소하면 해결할 수 있다. 나아가 결론에 대한 신념이나 논증 제시자의 성향을 나타내는 표현을 논증 제시 의도와 구분함으로써 우리는 의도 기준이 연역 논증과 귀납 논증을 구분하는 기준으로 제 역할을 할 수 있다고 결론짓는다.

The informative or important entities in utterances are focused and the focused items are usually accompanied by changes in phonetic manifestation. Phonetic realizations triggered by focus include changes of tonal contours as well as segmental strengthening. Focus in Korean is characterized by new phrase initiation, dephrasing, and initial tone contour with an enlarged pitch range in addition to segmentally lengthened initial segment. Focusing on the prosodic cues which play an important role in delivering the speakers' intention, this study aims to find out what intonational characteristics of Korean focus are realized by English learners of Korean. The English learners are divided into two groups according to their fluency in Korean, and the differences in focus realization between each group are discussed. Furthermore, the phonological and phonetic realizations of focus by English learners of Korean are compared to those by Korean native speakers. The results of this study yields two suggestions for Korean intonation education of L2 learners. First, the comparison between the two speaker groups can give better understanding in how and why the Korean intonation of English speakers is different from that of Koreans. Second, each phonological and phonetic characteristic of focus realization can weigh differently and its realization provides a criterion for evaluation of L2 Korean proficiency.

The optimal Load-Frequency Control law is presented with the performance criterion which includes the changing rate of governor speed. The authors propose two controllers. One is a dynamic controller using the method of state augmentation and the other is a constant gain controller with use of the trace function lemma by Kleinman. For a more practical realization, a reduced-order Luenberger observer is applied in order to identify unmeasurable states and power demand. The control schemees presented here are tested through the model developed by Elgerd, and the usefulness is demonstrated.

A simple realization of an alignment-free wireless power transmission (WPT) system is presented in this letter. The WPT system consists of a transmitter with three reconfigurable modes corresponding to various controllable magnetic field directions in the azimuthal plane and an algorithm for the optimum mode selection carried by sensing the reflected voltage of the system. Twelve light emitting diodes (LEDs) are used to confirm the on- and off-state of LEDs powered wirelessly by the transmitter at every $15^{\circ}$ of the azimuthal plane. A criterion voltage from the reflected power of the system is found by using the correlation between the reflected voltage and the on- and off-state of the LEDs. Simply by continuous; monitoring of the voltage from the system, the system maintains power to the LEDs. The system is realized by MATLAB/Simulink and a National Instrument data acquisition device (DAQ) board. Measurements using the system show on-state LEDs in the azimuthal plane except at the angles of $60^{\circ}$, $75^{\circ}$, $180^{\circ}$, and $300^{\circ}$.

An improved half-bridge LLC converter with a magamp auxiliary post-regulator is proposed in this paper. The function of the magamp is bypassed when the converter works within the low input-voltage range. Meanwhile, it operates as an auxiliary post-regulator when the input voltage is high. By changing the blocking time of the magamp, the dc gain of the converter can be extended. Hence, the input voltage range of the converter is extended. The realization of proposed topology does not require a complicated circuit. The controller of the magamp can be easily implemented using only passive components, transistors and an OP amp. The generalized operational principle is analyzed and the design criterion for the magamp is presented. Finally, a 25V output, 400W experimental prototype was built and tested for a 160-300V input-voltage range to verify the feasibility of the proposed method.

In this study, the analytic realization of chatter mechanism using radial basis neural network(RBNN) was introduced and compared with the conventional stability analysis. In this regard, the FFT and time series spectrum analysis was used as a criterion for the existence of chatter in end-milling force. The desired coded outputs of chatter was trained and finally converged to desired outputs. The output of the RBNN match well with the conventional desired stability lobe. Using this trained data, the stability boundary of the radial basis neural network was acquired using the contour plotting. As a result, the proposed stability lobe boundary using RBNN consists well with the conventional analytical boundary that is calculated in characteristic equation of transfer function in chatter dynamics. In this RBNN analysis, two input and three output parameters were used in this paper.

온라인 쇼핑몰은 인터넷을 통해 손쉽게 접근이 가능하기 때문에, 최초 구매의사가 발생한 시점으로부터 이에 대한 실제 구매가 실현되기까지의 기간이 오프라인 쇼핑몰에 비해 비교적 짧게 나타난다. 즉 오프라인 쇼핑몰의 경우 구매희망 물품을 바로 구매하기 보다는 몇 개의 물품들을 모아서 구매하는 행태가 일반적이다. 하지만, 인터넷 쇼핑몰의 경우 단 하나의 물품만을 포함하고 있는 주문이 전체 주문의 절반 이상을 차지한다. 따라서 온라인 쇼핑몰 데이터의 장바구니 분석에 전통적 데이터마이닝 기법을 그대로 적용할 경우, Null Transaction의 수가 지나치게 많음으로 인해 합리적 수준의 지지도(Support)를 만족시키는 규칙을 찾는 것이 매우 어렵게 된다. 이러한 이유로 온라인 데이터를 사용한 많은 연구는 동시성 기준을 여러 방법으로 확장하여 사용하였는데, 이들 동시성 기준은 명확한 근거나 합의 없이 연구자의 상황에 따라 임의로 선택된 측면이 있다. 따라서 본 연구에서는 온라인 마켓 분석에 적용되는 구매의 동시성 기준을 정확도 측면에서 평가함으로써, 구매의 동시성 기준 선정을 위한 근거를 제시하고자 한다. 또한 동시성 기준의 정확도가 고객의 평균 구매간격에 따라 상이하게 나타나는 것을 파악하여, 향후 고객의 특성에 따른 차별화된 추천 시스템 구축을 위한 기본 방향을 제시하고자 한다. 이를 위해 국내 대형 인터넷 쇼핑몰의 최근 2년간 실제 거래 내역을 대상으로 실험을 수행하였으며, 실험 결과 단골 고객의 구매 추천을 위한 분석의 경우 추천 범위와 분석 데이터의 동시성 기준을 맞추어 연관규칙을 도출하는 것이 바람직하며, 비단골 고객의 경우 대부분의 추천 범위에 대해서 분석 데이터의 동시성 기준을 비교적 길게 설정하여 연관규칙을 도출하는 것이 바람직한 것으로 나타났다.

The purpose of this paper is to examine the process of Islamic change in Indonesia since the 1970s, which is commonly called 'Islamic resurgence' or 'Islamization.' A brief analysis of the reasons for Islamic resurgence is followed by discussions on its long-term effects on the life of Indonesian Muslims. Shift in the ways Islamic matters have been treated in public, gradual realization of what Islamic groups have demanded in non-religious areas, stipulation of local regulation based on shariah and spread of radicalism are to be investigated one by one. With these examinations, it will be argued that the most significant change throughout the last four decades has been the surge of Islam as a reference point to interpret everyday life of Muslims. The dichotomy of 'Islamic' and 'non-Islamic' is instated as a key in Islamic discourse and the Quran and Hadith, as a criterion to judge whether certain views and behavior are Islamic or not. These have strengthened the position of scripturalism in Indonesian Islam. Islamic resurgence has also resulted in the acceleration of the diversification of Indonesian Muslims. Muslims with radical, fundamental, reformist, traditional and liberal views coexist, competing for stronger social and religious influences. As radical and fundamental groups have been more active in dealing with socio-political affairs recently, whether their active involvement will result in wider influences over the ordinary Muslims is the key to understand the future dynamics of Indonesian Islam.
