This study is to investigate the influence of the manufacturing company and fineness of cement on bleeding of concrete. According to the results, as fineness of comment increases, slump and air content of fresh concrete decrease, and setting time is shortened. The amount of bleeding abates with an increase of fineness, and it is confirmed that bleeding does not occur especially in the case of B8000. it is confirmed that bleeding does not occur. Bleeding speed is higher in the case of OPC A than in the case OPC B, and grows low with an increase of fineness. It also becomes highest at about 60 minutes, and shows slow tendency in W/C of 45% in comparison with W/C of 50%. And It is confirmed that relativity between fineness of cement and the final amount of bleeding is very favorable. As the properties of hardened concrete, compressive strength do not make much difference between OPC A and B is little, and increases with an increase of fineness.

To study the prevalence of common dermatoses 37,638 and 30,286 new outpatients who visited dermatology clinic with Hanyang University Hospital from January 1981 to December 1985 and from January 1986 to December 1990, respectively. Among the 37,638 outpatients in the first 5 years, the total number of male patients were 18,107(48.1%) and female patients were 19,531 (51.9%). Among the 30286 outpatients in the last 5 years, the total number of male patients were 14,705 (48.6%) and female patients were 15,581 (51.4%). In the both periods, the most frequent age groups was 21-30 (27.3%,25.2% respectively). The 15 common dermatoses, bacterial infection, seborreic dermatitis, drug eruption, verruca, syphilis, psoriasis, herpes zoster, and hypopigmentary disorder, in order of frequency. In thelast 5years, dermatophytosis, contact dermatitis, urticaria, acne, other eczema, atopic dermatitis, seborrheic dermatitis, bacterial infection, drug eruption, verruca, gerpes zoster, psoriasis, hypopigmentary disorder, scabies and syphilis were the 15 common dermatoses, as frequency. In both periods, the dermatosis which showed annually increasing tendency was dermatophytosis and those of decreasing tendency was bacterial infection. In the both periods, dermatophytosis, urticaria, bacterial infection, seborrheic dermatitis, verruca, and hypopigmentary disorder occurred most frequently during the summer season, and the incidence of other ecxema, scabies, atopic dermatitis, and herpes zoster increased during the winter season.

In order to provide a reliable M-Commerce, a payment solution with security functions should be required. User's mobile terminals used in M-Commerce services are diversifying to cellular phone, PDA, Smart phone etc. Among them, integration of PDA's interface and mobile connection overcomes the weak point of existing cellular phone depending on information via the internet. In this paper, the Secure Card based protocol for a credit card transaction on PDA using ECC is presented. Secure Card module on this protocol encrypts user's information such as private information, delivery information and credit card information and stores it on PDA in order to free from inputting information whenever it is used. This scheme also offers security services on M-Commerce including authentication, confidentiality, integration, non-repudiation and so on.

Anoxic and Oxic process with contact media is used to remove an organic matter, nitrogen and phosphorus in sewage which derives from domestic wastewater. Experiments have been done with various conditions that concentration of oxygen can be 3㎎/ℓ, 4~5㎎/ℓ and 5~6㎎/ℓ by controlling an retention time can be 10hr, 12hr and 14hr, return rate can be 0%, 100% and 200%. As the concentration of oxygen is 2~3㎎/ℓ, The rate of removal of BOD. COD, SS, T-N and T-P is 87%, 76%, 82%, 34% and 24%. As the concentration of oxygen is 5~6㎎/ℓ, The rate of removal of BOD, COD, SS, T-N and T-P is 92%, 84%, 88%, 45% and 33%. In the rate of removal of an organism, nitrogen and phosphorus thus It well be known that the rate of removal an organic matter, nitrogen and phosphorus will be increased as the concentration of oxygen becomes higher. As th retention time is increased, the rate of removal of BOD, COD, SS, T-N and T-P is gradually higher in the rate of removal of an organic matter, nitrogen and phosphorus. Because contact time and contact area will be increased, which generates active substrate transfer and metabolic react according to increment of retention time. As the return rate is increased, The rate of removal of BOD, COD and SS is likely to be increased, In the case of T-N, It is also increased by 28% at 0% of the return rate and by 60% at 200% of the return rate. In the case of T-P, however, It is deceased , as the return rate is increased by 42% at 0% of the return rate and by 30% at 200% of the return. As the return rate is increased the retention time is decreased, which causes less activity of bacteria which affects that the rate of removal of Phosphorus is decreased.

We have analyzed the genetic relationship among the silkworm (Bombyx mori) strains using RAPD-PCR. A total of 45 polymorphic RAPD markers amplified from 9 different primers were used to analyze the genetic relationship among the seven silkworm strains. The genetic similarity coefficients among the seven silkworm strains were estimated using the RAPD markers by UPGMA method. The genetic similarity coefficient between 127 and CS120 was 0.261. This value was lower than any other genetic similarity coefficient among the strains tested. And 127-specific RAPD band patterns were observed in 3 primers from 9 polymorphic primers used. This study makes possible phylogenetic identification among the Bombyx mori strains in the molecular level using RAPD-PCR techniques.

Conventional method of generating meteorological surfaces over geographic areas often neglects the elevation effect which is considered to be a single most important control over local climate. Deviation of the estimates may exrled practical limits at some areas with complex toprlgraphy. A digital map featuring coordinates and elevation data of 72 weather stations in Korea were joined with hourly weather(trmperature, relative humidity, precipitation and wind speed) observations at the stations by using a geographic information system software. An inverse distanre weighted interpolation was done on the point features to generate prim-itive meteorological and elevation surface grids consisting of 430×600 cells, respectively. Elevation difference at each cell between the United States Geological Survey's 1 km digital elevation model and this virtual ele-vation surface was calculated. Known relationships between meteorological elements and the elevation differ-ence were used to derive "correction grids" representing the potential effects of elevation difference at each grid cell. The correction grids were added or multiplied to the primitive meteorological surfaces to obtain ele-vation-corrected estimates for corresponding elements. This srheme was applied to hourly data of 27 March 1998 to generate the elevation-corrected mrteorological surfaces. Observed data of 350 automated weather sta-tions were used to partially validate the accuracy of the results. This simple scheme sHelved a feasibility of a near-real time generation of hourly meteorological surfaces for temperature and rainfall with an affordable error range.

제7차 교육과정기의 초등 과학교과 현장학습 실태조사

김은진,임채성 한국초등과학교육학회 2003 초등과학교육 Vol.22 No.2

The purpose of this study was to investigate about current status of science field study in elementary schools. A total of 72 elementary teachers in Busan and Gyungnam districts were involved and the data from questionnaire was gathered. The questionnaire was comprised two parts: items on general level include the epistemological aspect and actual condition and items on concrete level according to chapters of elementary school science curriculum. The major findings are as follows: 1. May teachers cognize the requirement of science field study in 7th Korean elementary school science curriculum is larger than 6th one. But they respond the actual number of science field study in 7th curriculum is nearly equal to 6th. 2. In analysis to grades, the actual number of field study decrease as grade is high. 3. In the science content aspects, the requirement of field study is the largest on biology domain and earth science domain. 4. Many teachers have pointed out "the difficulty of administration for field study" and "inappropriated surrounding their school" as the problems of science field study in elementary school.
