The intent of this study is to investigate the characteristics of block formation and lot subdivision an the commercial strip for rental office buildings and to suggest the size and form of block and lots for urban commercial areas. Teheran-Ro' is selected as a case site to analyze the characteristics of the commercial strip. The general characteristics of the commercial street for office building can be summarized as follows; I) Conceptually, it is a collective form of commercial facilities in a line along the street. ii) Various types of the commercial building are possibly categorized , according to its site location, such as in the commercial core, in the neighborhood center, or in the site facing major artery. iii) The arrangement of blocks differs in scale and form due to the condition of a facing road. iv) The buliding design and the site plan of rental office buildings is made in a way of fitting the condition of a lot proper, and the acquisition of vehicular access and parking space mainly affects the decision making in the design. The analysis by the comparison of different blocks and lots reveals the following results , concerning the issues of their size and form; i) Classification of road's function is determined by the width of it. ii) The formation of block seems to be decided in a similar way regardless of road conditions. And the size of a commercial blocks is determined without considering the possibility of combination of lots in a block and the arrangement of a building in a lot. iii) Various forms of the building in different size lost appears and consequently cause disharmony in terms of urban grain, mainly because the standard for a lot size considering the position of a building in the lot has not been provided. iv) The space between buildings which is left unused results in inefficient land -use, when the building arrangement in a lot is not properly considered in the design of lot's size and form. v) The regular arrangement of blocks irrespective of their subdivision and efficiency causes the difficulty in easing the traffic and introducing the car access. All of these planning problems result in the inefficiency in land-use, in architectural design, and in building function. Based on the analysis , some of the planning guidelines for the block in a commercial strip for office buildings and its subdivision into lots are proposed here. First, for a block design; i) Blocks is to be arranged in a way of emphasizing the linear shape of the commercial strip, and strengthening the characteristics of the street and the function of collected facilities. ii) The different size blocks and hierarchically interconnected roads are to be arranged mainly considering their function. iii) the form of a block is to be planned principally according to the condition and the function of surrounding roads, leaving room for the flexibility in application . iv) the size of a block is to be designed in consideration of the lots in it fundamentally. Also, the combination of lots and the building form and scale in a joint lot are to be fully taken into consideration. Secondly. for a lot subdivision adn its use; i) The appropriate size and form of a lot is to be planned according to the width of the road, to design an efficient rental building for business in it. ii) The lot subdivision is to be made considering the location and function of each lot and the possibility of lot combination. iii) Encouraging the vertical(to street derection) combination of lots, the form of lots is to be decided . iv) For the efficient office building layout within a lot, narrow and deep lot shape is highly recommended.

유아교육과정의 포스트모더니즘 관점에서 본 멀티미디어의 활용 탐색

양옥승,강현미,나은숙 덕성여자대학교 2006 德成女大論文集 Vol.35 No.-

The utilization of multi-media to deliver education content has been rapidly increasing recently in early childhood education institutions. However, in many cases multi-media is used as classroom tools without thorough review of their educational function and possible problems. According to Grundy(1991), the use of any medium in a curriculum should not be accepted without critical review. In addition, the medium should also be assessed as an area of overall curriculum development. Accordingly, this research studies the utilization of multi-media from a postmodern perspective of the early childhood curriculum. It emphasizes the following points: First, multi-media should deliver content that pursues diversity and multiplicity considering the socio-cultural context of the learners. Second, multi-media should be used for not only individual activities but also collaborative work to promote interaction. Third, multi-media should be capable of encouraging the active participation of the learners. In conclusion, this research suggests that the use of multi-media in early childhood education institutions is significant not only as an additional teaching tool but also as the means to enable new approaches to early childhood education curriculum.

Profile^(Ⓡ), ProTaper™ 및 K^(3TM) Ni-Ti파일의 과기구 조작이 치근단공 변위에 미치는 영향

양현,양인석,황윤찬,황인남,윤숙자,김원재,오원만 대한치과보존학회 2007 Restorative Dentistry & Endodontics Vol.32 No.2

본 연구는 ProFile, ProTaper 및 K^(3)를 이용하여 과잉 기구 조작에 의해 근관 성형 시 근관의 만곡형태와 Ni-Ti 파일의 종류에 따라 치근단공이 어떻게 변위 되는지를 비교 분석하고자 시행되었다. 본 실험에서는 레진모형근관으로 J자와 S자의 근관 형태가 재현된 ENDO-TRAINING BLOC을 사용하였다. 근관 성형 기구로는 ProFile^(®), ProTaper™, K^(3TM)를 사용하였다. 총 60개의 레진모형근관을 사용하였으며, 사용된 레진모형근관 및 Ni-Ti 파일의 종류에 따라 10개씩 6개의 군으로 나누어 근관성형을 시행하였다. 근관 성형 전·후 이미지를 Image-analyzing microscope 100X를 이용하여 얻고 Photoshop 7.0 프로그램을 이용하여 중첩하였다. 이미지 분석 프로그램을 이용하여 근관 성형 전·후 치근단공의 중심으로부터의 직경 변화량과 면적을 측정한 결과 만곡된 근관의 성형시 치근단공이 주로 만곡의 외측으로 변위됨을 나타내며 ProFile이 ProTaper나 K^(3) 보다 통계적으로 유의성이 있게 작은 변화량을 나타내어 근관성형시 바람직한 기구임을 시사한다. This study was done to evaluate transportation of the apical foramen after 0.5 mm overinstrumentation by ProFile, ProTaper and K^(3) in simulated resin root canal. Sixty simulated resin root canal with a curvature of J and S-shape were divided into two groups. Each group consisted of three subgroups with 10 blocks according to the instruments used: ProFile^(®), ProTaper™, and K^(3TM). Simulated resin root canal was prepared by ProFile, ProTaper and K^(3) with 300 rpm by the crown-down preparation technique. Pre- and post-instrumentation apical foramen images were overlapped and recorded with Image-analyzing microscope 100X (Camcope, Sometech Inc, Korea). The amounts of difference in width and dimension on overlapped images were measured after reference points were determined by Image Analysis program (Image-Pro^(®) Express, Media Cybernetic, USA). Data were analyzed using Kruskal-Wallis and Mann-Whitney U-test. The results suggest that ProFile showed significantly less canal transportation and maintained original apical foramen shape better than K^(3) and ProTaper.

소아의 구강으로부터 분리한 비수용성 글루캔 형성 억제세균의 Streptococcus mutans 치태 형성에 대한 억제 정도와 분리 세균속의 타액내 농도가 전체 세균의 농도에 미치는 영향을 본 결과 다음과 같은 결과를 얻었다. 구강으로부터 분리한 비수용성 글루캔 형성 억제세균의 효과를 비커 와이어 검사로 본 결과,교정용 와이어상에 형성된 치태의 무게가 Streptococcus mutans 단독배양시 152mg에서 Enterococcus durans,Lactobacillus acidophilus,Streptococcus oralis와의 혼합배양시 각각 4mg,78mg,72mg으로 감소되였다.Streptococcus mutans의 생균수는 단독배양시 ml당3.6×10×10 개에서 Enterococcus durans,Lactobacillus acidophilus,Streptococcus oralis와의 혼합배양시 각각 ml당 1.4×10 ,5.6×10 ,3.8×10 으로 감소하였다.소아로부터 얻은 타액을 BHI agar에 접종하였을 때의 생균수는 4.8×10 에서 1.3×10 이었으나,이러한 전체 세균의 농도는 타액내 Enterococcus, Lactobacillus, Streptococcus mutans를 억제하는 Streptococcus의 농도와 관련이 없었다. 이상의 결과를 종합하면 소아의 구강으로부터 분리한 비수용성 글루캔 형성 억제 세균의 Streptococcus mutans 치태 형성에 대한 억제는 Streptococcus mutans의 증식을 억제하여 일어났으며, Enterococcus,Lactobacillus,Streptococcus mutans를 억제하는 Streptococcus의 구강내 농도는 구강 즉 타액내 전체 세균의 농도에 영향을 미치지 않았다. The inhibitation degree of the isolated on plaque formation of Streptococcus mutans,and the effect of these bacterial genus on the concentration of total bacteria in saliva were assessed with the following. The effectiveness of the isolated on the inhibitation of plaque formation was assessed culturing Streptococcus mutans in the beaker with orthodotic wires.The mean weight of plaque produced on a wire was 152mg in the culture of Streptococcus mutans only,whereas being reduced to 4mg,78mg,or 72mg in the combined culture of Streptococcus mutans and Enterococcus durans,Lactobacillus acidophilus,or Streptococcus oralis.The colony forming units(CFU) of Streptococcus mutans were 3.6×10 per ml in the culture of Streptococcus mutans,only,wheras 1.4×10 , 5.6×10 ,or 3.8×10 per ml in the culture of Streptococcus mutans and Streptococcus mutans and Enterococcus durans,Lactobacillus acidophilus,or Streptococcus oralis.When saliva from children was 4.8×10 to 1.3×10 per ml of saliva.The concentration of Enterococcus durans,Lactobacillus or Streptococcus inhibiting Streptococcus mutans in saliva was not proportioned to that oh total bacteria replicated on brain heart infusion agar. These results indicate that the isolated bacteria inhibited the replication of Streptococcus mutans,resulting into inhibiting the formation of plaque,but the concentration of Enterococcus,Lactobacillus,or Streptococcus inhibiting Streptococcus mutans,in saliva might not affect the total bacterial concentration of saliva.

The transaction tables of the existing association algorithms have two column attributes: It is composed of transaction identifier (Transaction_id) and an item identifier (item). In this kind of structure, as the volume of data becomes larger, the performances for the SQL query statements came applicable decreases. Therefore, we propose advanced association rules algorithm of n-items which can transact multiple items (Transaction_id, Item 1, Item 2, ... , Item n). In this structure, performance hours can be contracted more than the single item structures, because count can be computed by query of the input transaction tables. Our experimental results indicate that performance of the n item structure is up 2 items better than the single item. As a result, the proposed algorithm can be applied to internet shopping, searching engine and etc.

선우양일,박현숙,탁연수,최윤정,김광 동아대학교 환경문제연구소 1997 硏究報告 Vol.20 No.1

Chitin was converted to chitosan by deacetylation, and then carboxymethyl chitosan(CM-chitosan)was obtained by carboxymethlation of chitosan. The antibacterial activity was estimated using the miminum inhibitory concentration (MICwt%) assay. MICwt% of Bacillus subtilis, Escherichia coli, Pseudomonas aeruginosa, candida albican and Staphylococcus aureus were 0.5, 0.5, 0.25, 0.25, 0.75 respectively. CM-chitosan was tested for antifungal antivity which is measured the inhibition of hyphal extension of the fungi. MIC_(50)wt% of CM-chitosan was shown half growth of the experimental over control group. MIC_(50)wt% of Penicillium citrinum, Myrothecium verrucaria and Verticillium albo-atrum were 0.5, and Gliocladium virens was 0.75, respectively. These results showed that CM-chitosan had the high inhibitory effect on the growth of the bacteria and fungi.
