중도문화의 지역성

박중국(Park, Jung-kuk) 중앙문화재연구원 2012 중앙고고연구 Vol.0 No.11

중부지역의 원삼국문화는 소위 ‘中島類型文化’로 대표된다. 박순발에 의해 제창된 중 도유형문화란 경질무문토기ㆍ타날문토기ㆍ회흑색무문양토기의 공반, ‘呂(凸)’자형 주거지, 즙석식 적석묘 등의 요소를 특징으로 하며, 이는 한성백제의 기층문화이자 濊系집단의 고고학적 문화로 이해된다. 이러한 견해는 이후 연구의 근간이 되었다는 점과 더불어 현재까지도 폭넓게 수용되고 있다는 점에서 매우 획기적인 것으로 평가되고 있다. 최근 조사의 폭증으로 인해 중부지역의 고고학적 양상이 매우 다양하게 확인되면서 기존 중도유형문화의 틀로는 이를 포괄할 수 없다는 인식이 증가함에 따라 중도유형문화의 개념에 대한 비판이 제기되게 되었다. 따라서 본고는 중도유형문화를 재검토하여 그 개념을 재정립하고, 기존에 간과해왔던 중부지역의 지역성에 대한 분석을 시도하였다. 그 결과 ‘중도유형문화’라는 용어는 ‘중도 문화’로 대체하고 그 의미를 대폭 수정하여 ‘경질무문토기ㆍ타날문토기가 공반되는 ‘呂’ 자형 주거지의 공통분포권’으로 정리하였다. 그 시간적인 범위는 원삼국기부터 백제 한 성기까지이며, 공간적 범위는 중부지역에서 서해안 일대와 안성천유역을 제외한 지역에 해당된다. 중도문화를 구성하는 토기-주거지-분묘는 서로 대등한 요소가 아니라 다른 공간적 위계를 가진 요소이기 때문에 이를 기준으로 하여 大-中-小지역으로 이어지는 위계적 지역 구분을 시도해 보았다. 大지역권은 주거지의 爐시설을 기준으로 구분할 수 있다. 쪽구들 주거지가 주로 분포 하는 서울ㆍ경기지역과 노지 주거지가 주로 분포하는 영서지역과 영동지역으로 대별되는데, 이는 각각 韓濊의 생활양식이 투영된 것으로 판단된다. 中지역권은 수계와 지형에 따라 구분이 가능하며, 서울ㆍ경기지역은 북부와 남부, 영서지역은 북한강유역과 남한강유역으로 구분할 수 있으며, 영동지역은 해당되지 않는다. 경기북부지역은 원삼국기에서 백제 한성기로 이행하면서 취락규모가 축소되는 경향이 확인되며, 경기남부지역은 반대로 취락규모가 확대되는 경향이 관찰된다. 북한강유역에 는 낙랑계유물의 빈도가 높게 확인되는 반면, 남한강유역에는 낙랑계유물이 거의 확인되지 않고 있다. 이러한 지역차의 배경으로는 경기지역의 경우 백제와의 정치적 역학관계가, 영서지역의 경우는 낙랑과의 교역망과 관련된 것으로 이해된다. 小지역권은 현재 적석분구묘를 기준으로 추출할 수 있으며, 이는 원삼국기의 강력한 소국의 존재를 시사하는 것으로 이해된다. 그 중 서울의 송파구 일대는 伯濟國, 연천지역은 臣 濆 沽國에 해당되는 것으로 추론하였다. The notion of Jung-do cultural assemblage, which claims that the cultural characteristics of the Proto-three kingdoms period in central Korea as the association of specific types of potteries, dwellings and burials, has been widely accepted for a long time. However, as last 20 years of excavation much revealed new archaeological data, the argument shows clear limitation and loosing its power of explanation. This thesis aims to have a critical review on the Jung-do cultural assemblage first, and then redefine Jung-do archeological culture through detailed analysis of potteries, dwellings and burial types. The analysis shows that the ‘呂’-shaped dwellings, associated with hard plain pottery and beating patterned pottery, that widely distributed in central Korea, now are defined as new features of redefined Jung-do archeological culture. However, it was also noticed that there are regional variations, like heating system types of the dwellings – east and west part of central Korea. This seems to reflect different lifestyle, likely ethnic difference. Even more, the burial types showed clear differences among regions – it might be a signal of the growth of regional polities, and/or the result of their ‘peer polity interaction’.

Even though Accreditation Board of Engineering Education in Korea (ABEEK) started its accreditation procedures, the faculty still have difficulties in preparing the accreditation because there is little practical examples of the preparing procedure. This paper explains the practical procedure to determine the educational objectives and the outcomes, which is the first part of the accreditation preparing procedure. The educational objectives of the program should be expressed by the specific and assessable sentences and their contents should comply with the demands of the educational community, the objectives of the educational institute, and the characteristics of the program. The program outcomes consist of 12 outcomes from ABEEK and additional outcomes that reflect the characteristics of the program. Since the educational objectives and the outcomes should have the full connection among the objectives of the institute and the course objectives, the relationships among them should be checked using the relationship analysis matrix.

This research utilized the Analytic Hierachy Process(AHP) methodology for evaluating usability of word-processor. Subjective evaluation of interface usability, especially for word-processor, has been done with respect to such measures as completion time, human error, and functionality. And questionnaires, interviews, and verbal protocols are among the most common methods for data collection. However, since there are many functions or capabilities in any word-processor, and worse yet, complicated hierarchical relationships among them, it is not easy to evaluate the functionality of word-processors as a whole. Highlighting this, the present research used the AHP methodology to build a structure of software capabilities. Twenty-three university students participated in the experiment. They were asked to rate the importance of 43 selected major functions of three widely-used word-processors. The results from the AHP methodology showed that respect to functionality the "Edit" function is the most highly evaluated, followed by "File" and "Table" functions. In each of those major functions, the structure of sub-functions were also set up. The results can be applied to study the user'priority among various capabilities of user interface.

Rayleigh signal fading phenomena due to multipath propagation in wireless communication can be simulated using the SOS(sum-of-sinusoids) fading channel model. Fading channel model is very simple simulator based on the SOS and has been widely used. However, It has some short-comings. Its time correlation properties based on the simulated waveform do not correspond to the statistical ones. In this paper, the difference between statistical and time properties of fading channel model is examined and new simulator is proposed.

N-Benzoyl-4(5)-nitroimidazole의 가수분해반응에 대한 속도론적 연구

박국애,정윤주,이종팔 東亞大學校 2000 東亞論叢 Vol.37 No.-

The rate constants for the hydrolysis of N-benzoyl-4(5)-nitroimidazole were determined in water at the 25℃ under pseudo first order conditions by uv/vis spectrophotometer. The pH independent reaction and the hydroxide ion catalyzed reaction were observed from pH 6 to 1 and above pH 6, respectively. The D2O solvent isotope effect couldn't observe in the pH independent reaction, that is, k0 H₂O/k0 D₂O 1.0. Activation parameters in the water catalyzed reaction were calculated to △H‡ =12.3 Kcal and △S‡ = -32.6 e.u. respectively. Thus, the water catalyzed reaction is more important to nucleophilic attack to the carbonyl carbon than the protonation of the leaving group In the transition state. Above pH 6 the hydrolytic reaction showers hydroxide ion catalyzed reaction.
