행위자의 주관과 객관의 이중성은 어떻게 양립가능한가?

김선희(Sun-Hie Kim) 한국철학회 2017 철학 Vol.0 No.133

주관적이면서 객관적이기도 한 인간의 이중적 본성이 양립한다는 것을 어떻게 설명할 수 있는가? 김재권은 행위론에서 바로 이 문제를 제기한다. 인간 행위에 대한 기존의 대표적인 이론들, 인과론과 비인과론은 행위를 바라보는 주관적 관점과 객관적 관점을 이원적으로 분리하거나 어느 한쪽으로의 환원을 시도한다. 필자는 주관과 객관의 양립가능성 문제에 접근하는 기존의 모델들을 비판적으로 검토한 후 새로운 대안을 제안할 것이다. 여기서 이 문제를 해명하기 위한 시도의 하나로 김재권의 투사 및 시뮬레이션 모델을 검토하고 그것이 갖는 설명력과 한계를 논의한다. 나아가 필자가 고안한 시뮬레이션 집단사고실험 모델은 그러한 한계를 해결할 수 있다는 것을 보임으로써, 주관과 객관의 이중성을 해명하는 하나의 모델이 될 수 있다는 것을 논의할 것이다. How can we explain that the dual nature of human beings, both subjective and objective, is compatible? Kim Jaegwon poses this problem from his action theory. Existing representative theories of action, causal theory and non-causal theory, attempt to divide the subjective viewpoint and the objective stance of agents into two, or try to reduce to one side. I will critically review existing models approaching the issue of compatibility between subjectivity and objectivity and suggest new alternatives. Here, I examine Kim’s projection thesis and simulation model and discuss its explanatory power and limitations. Furthermore, I will argue that the model of group simulation thought experiments I designed can be a model for explaining our dual nature of subjectivity and objectivity by showing that it can solve such limitations.

Polycrystalline germanium (Ge) thin films were grown by metal organic chemical vapor deposition (MOCVD) using tetra-allyl germanium [$Ge(allyl)_4$], and germane ($GeH_4$) as precursors. Ge thin films were grown on a $TiN(50nm)/SiO_2/Si$ substrate by varying the growth conditions of the reactive gas ($H_2$), temperature ($300-700^{\circ}C$) and pressure (1-760Torr). $H_2$ gas helps to remove carbon from Ge film for a $Ge(allyl)_4$ precursor but not for a $GeH_4$ precursor. $Ge(allyl)_4$ exhibits island growth (VW mode) characteristics under conditions of 760Torr at $400-700^{\circ}C$, whereas $GeH_4$ shows a layer growth pattern (FM mode) under conditions of 5Torr at $400-700^{\circ}C$. The activation energies of the two precursors under optimized deposition conditions were 13.4 KJ/mol and 31.0 KJ/mol, respectively.

1994년 노스리지 지진 이전 우수한 연성능력을 보유한 내진상세로 생각되던 WUF-B 접합부의 기둥-보플랜지 용접위치에서 발생 한 취성파괴는 WUF-B 접합부에 대한 새로운 고찰을 요구하였다. FEMA(Federal Emergency Management Agency)의 후원으로 SAC Steel Project에서는 WUF-B 접합부의 스캘럽(Weld access holes) 형상, 용접과정, 용접재료 등을 개정한 내진상세를 FEMA-350에 제안하 였다. AISC Seismic Provisions(2005)에서는 WUF-B 접합부를 OMF(Ordinary Moment Frames)로만 사용하도록 규정하고 있다. 본 연 구에서는 SM490 및 SN490 조립형강을 이용하여 FEMA-350에 제시된 WUF-B 상세 규정을 따라 강종(SM, SN), 보플랜지두께, 보의 춤을 변수로 기둥-보 접합부 실대 실험체 2개를 제작하여 실험을 수행하였으며, 내진성능 평가를 위한 가력 방법 및 내진성능을 평가하였다. JB-1, JB-2 실험체는 AISC Seismic Provisions(2005)에서 제시하고 있는 OMF와 SMF 내진성능을 만족하는 결과를 나타났으며, 보플랜지 두께와 보의 춤에 따른 WUF-B 접합부의 내진성능이 재정의 될 필요가 있는 것으로 사료된다. The brittle failure where is occurred the welding position of column-beam flange of WUF-B connection that consider about a seismic detail possess a superior ductility capacity before Northridge earthquake 1994, require newly study about WUF-B connection. SAC Steel Project suggests a seismic detail to FEMA-350 by supporting of FEMA. It revise shape of weld access holes of WUF-B connection, welding processand welding material etc, In spite of these revision, AISC Seismic Provisions (2005) prescribe WUF-B connection using an only OMF. Recently in Korea, as the earthquake of about seismic intensity 5 occur, the necessity of revision for connection seismic detail comes to the front in Korea and FEMA-350 connection seismic details are going to include in KBC-2008 as it is. In this study, two column-beam connection specimens were marked by using SM490, SN490 built-up H-section, and based on WUF-B detail prescription of FEMA350. The parameters of the specimens are types of steel (SM, SN), and evaluate the capacities of structure and seismic by experiment. Finally we confirm a superior ductility capacity aboutspecimens JB-1 and JB-2, using SM490 and SN490,and these specimens had sufficient OMF and SMF seismic capacity, as indicated in AISC Seismic Provisions (2005).

Digital decimation filters are used in various digital signal processing systems using ADCs, including digital communication systems and sensor network systems. When the sampling rate of digital data is reduced, aliasing occurs. So, an anti-aliasing filter is necessary to suppress aliasing before down-sampling the data. Since the anti-aliasing filter has to have a sharp transition band between the passband and the stopband, the order of the filter is very high. However, as the order of the filter increases, the complexity and area of the filter increase, and more power is consumed. Therefore, in this paper, we propose two types of decimation filters, focusing on reducing the area of the hardware. In both cases, the complexity of the circuit is reduced by applying the required down-sampling rate in two times instead of at once. In addition, CIC decimation filters without a multiplier are used as the decimation filter of the first stage. The second stage is implemented using a CIC filter and a down sampler with an anti-aliasing filter, respectively. It is designed with Verilog-HDL and its function and implementation are validated using ModelSim and Quartus, respectively.

This study was conducted to evaluate nutritional status with the analysis of the factors which might influence on the prevalent condition of nutrients-intake. 373 persons who are above 60 years old in Chung-Gu, Seoul were surveyed from March 15 to March 30 in 1985. Results were as follows ; 1. General Characteristics 1) Male respondents among the entire respondents comprised 54.3% and female respondents comprised 45.7%. As for age, male and female respondents comprised 55.0% and 37.2% respectively. 2) As for the educational level of the respondents, illiteracy was 49.9% which was the highest. and those who graduated elementary school was 28.1% which was the second highest. And as for the comparison of the education of the male and female respondents, the educational level of male respondents was much higher than that of female respondents. 3) As for the final occupation of the respondents, those who were engaged in commerce comprised 30.8% which was the highest rate, and who were engaged in agriculture comprised 20.1% which was the second highest rate. And those who were engaged in labor comprised 12.3%. 2. The State of Nutrients-intake The energy of the male respondents was 61.4% of RDA and the protein was nothing but 66.8% of RDA. Except vitamin A, vitamin $B_1$ and niacin, calcium, iron, vitamin $B_2$, vitamin C were lower than RDA (the range: $67.5%{\sim}97.3%$). The energy of the female respondents was 70.0% of RDA and the protein was 58.8% which were lower than RDA. Except vitamin A and vitamin $B_1$, calcium, iron, vitamin $B_2$ vitamin C, niacin were lower than RDA (the range: $68.2%{\sim}98.9%$). 3. The various factors related to nutrients-intake 1) The composition of family and the food environment those who were living with their spouses comprised 44.8% which was the highest rate, and those who were living with their son's family comprised 33.5% which was the second highest rate and those who were living with their doughter's family comprised only 4.6%. Those who were living alone comprised 16.4%. The correlation with nutrient intake didn't show a clear relation. 2) Socio-economic state Those who said that they lacked in living expense comprised 32.7% and those who said that they lacked in pocket-money comprised 23.9%, The female respondents outnumbered the male respondents in lacking living expense or pocket-money. In the correlation with socio-economic, there was no striking relation with education level. However, it was shown that little relation in energy, fat in male and also fat and iron in female. The living expense and the satisfaction in pocket-money had also little relation with energy fat and vitamin C in male. 3) Nutrition knowledge and food habit (a) The state of nutrition knowledge and food habit In nutrition knowledge, those who scored less than 60 points were 32.9%, and those who scored more than 90 points were 21.0%. In food habit, those who scored less than 60 points were 26.5% and those who scored more than 80 points were 45%. (b) The corelation with nutrition knowledge and food habit In case of female respondents, nutrition knowledge had a little relation with the intake of cabohydrate, iron, and vitamin C. And we couldn't see a distinct phenomenon in food habit.

In order to supply emotion service depending on user's emotional change in a mobile environment, various researches have been carried. This paper discusses a protocol for wireless charging and an embedded platform of the mobile emotional sensing device which supports that. Wireless charging process relieves user's vexatious task to charge the emotional sensing device. To support wireless charging, there are one basestation and several mobile devices. Basestation coordinates and controls the devices over wireless communication, as well as supplies energy. For 1:N communication we defines the network whose superframe is classified into four categories: a network join superframe, a charging request superframe, a charging superframe and an inactive superframe. Physical layer provides how to supply energy to the devices and communicate physically. Mobile device is equipped with energy charged circuits, which correspond with the defined energy supplying method, as well as bidirectional communication circuits. Mobile device monitors and analyzes its own battery status, and is able to send a request packet to basestation. Therefore, it can be charged before its battery is exhausted without user's perception.

김선희,김경희,Kim, Sun-Hee,Kim, Kyeong-Hee 한국수학사학회 2010 Journal for history of mathematics Vol.23 No.4

Chinese Taipei won the first place at the mathematics achievement of TIMSS 2007. Especially, there was a significant difference in the percentage of correct answers between Chinese Taipei and Korea, and Chinese Taipei' percentage of correct answers was higher than Korea. This study compared the education system, mathematics instruction environment, and instructional activities of two countries. And for algebra, curriculum and textbooks were compared between two countries based on TIMSS 2007 framework. It was found that Chinese Taipei emphasized homework and test, and MCFL of that was low. Their textbook was formal, and induced the hasty abstraction, Also, some themes were introduced earlier than Korea and repeated across different grades. TIMSS 2007 결과에서 국저l 성취 순위 1위를 차지한 대만에 비해 우리나라는 대수 영역에서 통계적으로 유의하게 낮은 정답률을 보였다. 이에 본 연구에서는 대만의 목표, 수학 수업 환경, 수학 수업 활동을 우리나라와 비교하고, 대수 영역의 교육과정을 구체적으로 살펴보았다. 특히, 우리나라의 정답률이 대만의 정답률에 비해 낮은 대수 영역의 '패턴'과 '대수식'의 주제의 개념 도입 순서, 교과서 내용 전개에 대하여 TIMSS의 평가목표별로 분석하였다. 일반적으로 대만의 수학교육은 학생 특성으로 연해 교사들이 수업에 제약을 많이 받고 있었고 우리나라보다 숙제와 시험을 강조하는 경향이 있었다. 대만의 교과서는 정의, 성질 위주로 제시되는 다소 형식적인 모습이었으며 다소 성급한 유도하고 있었다. 그리고 수의 연산 법칙 문자, 방정식, 부등식, 곱셈공식, 이차 방정식, 피타고라스의 정리 등의 내용이 우리나라보다 이른 시기에 도입되고 여러 학년에 걸쳐 중복하여 다루어지는 경향을 보였다.

This paper presents a method for automatically detecting Korean prosodic boundaries using both acoustic and grammatical information for the performance improvement of speech information processing systems. While most of previous works are solely based on grammatical information, our method utilizes not only grammatical information constructed by a Maximum-Entropy-based grammar model using 10 grammatical features, but also acoustical information constructed by a GMM-based acoustic model using 14 acoustic features. Given that Korean prosodic structure has two intonationally defined prosodic units, intonation phrase (IP) and accentual phrase (AP), experimental results show that the detection rate of AP boundaries is 82.6%, which is higher than the labeler agreement rate in hand transcribing, and that the detection rate of IP boundaries is 88.7%, which is slightly lower than the labeler agreement rate.

한국어 원거리 음성의 지속시간 연구

김선희,Kim, Sun-Hee 대한음성학회 2005 말소리 Vol.54 No.-

This paper presents durational characteristics of Korean distant-talking speech using speech data, which consist of 500 distant-talking utterances and 500 normal utterances of 10 speakers (5 males and 5 females). Each file was segmented and labeled manually and the duration of each segment and each word was extracted. Using a statistical method, the durational change of distant-talking speech in comparison with normal speech was analyzed. The results show that the duration of words with distant-talking speech is increased in comparison with normal style, and that the average unvoiced consonantal duration is reduced while the average vocalic duration is increased. Female speakers show a stronger tendency towards lengthening the duration in distant-talking speech. Finally, this study also shows that the speakers of distant-talking speech could be classified according to their different duration rate.
