At the time of research, middle school students gave rise to lots of social problems. It might be remedied by the proper education and leisure in a way. It was the physical activity that they liked most to any other. But the lack of physical education and facility could not be adequate to their needs. So this research was carried out to employ the urban park in the physical education and leisure space. And the followings were the things which were connected with the solution. It was not what all kinds of park should be physical park but the park which had completed facilities or not could be used as it, because there was a physical park in the current urban park act. A self-governing body had to realize the lack of physical education space and facility so as to establish an ordinance. And the problems which could be occurred during school hours could be solved by grouping schools which lay adjacent to a park. So walking and shuttle bus could help it.

미래 융합산업 표준 전략: 전기 자동차 충전 표준과 스마트그리드 통신 표준 충돌 사례

Based on the stakeholder theory, this paper analyzes a clash of standards in Korea's Electric Vehicle(EV) market, particularly between an EV charging standard and a smart grid communication standard in 2012~2013. For charging, EV is connected with the electric power grid and simultaneously exchanges data regarding the charging status. When EV is connected with the power grid, a clash between two standards may arise. It actually happened when BMW entered into the Korean EV market with the DC Combo charging system. In that course, the frequency interference occurred between the EV data communication technology adopted by BMW and the AMI(Advanced Metering Infrastructure) for the smart grid system in Korea. Standardization of Korea's EV charging systems was required to solve this problem. However, it had been delayed due to the confrontation between various stakeholders involved in the process of standardization. It lasted until the DC combo was accepted as one of the Korea EV charging standards(KSAE SAE 1772-2040, 2014.1) by KSAE(The Korea Society of Automotive Engineers) in January 2014. This is an interesting case in the age of convergence. As it deals with the standard competition not among EV standards, but a clash between the EV industry and the smart grid, i.e. electric power industry, it addresses the necessity to consider standardization processes between different industries. This study draws on the stakeholder theory to analyse the dynamics of the standard clash between EV charging systems and the smart grid system, which is a unique example of standard clash between different industries. We expect such clashes to increase in the age of convergence.

Intussusception in adult is a rare disease and laparotomy is usually considered because of the probability of malignancy. Especially with obstruction symptom or sign, it might be needed emergency operation. This case was a simultaneous development of small bowel intussusception and acute hepatitis A. The patient had abdominal pain and vomiting. Intitial laboratory examination with elevated aminotransferase revealed that the diagnosis was acute hepatitis. As managing acute hepatitis, the abdominal pain was not improved and the patient had tenderness on periumbilical area on physical examination. A jejunal intussusception with a lead point was proved on the abdominal computed tomography scan. Fortunately, symptom of intussusception was relieved while nulli per os (NPO) and intravenous hydration. After recovery of acute hepatitis, laparotomy was done. The lead point was 2.5×3.0 cm sized hamartoma. This was the case that the symptom of intussusception was confused with that of acute hepatitis.

본 논문은 장거리 표적영상을 획득하기 위한 빗각촬영기법(LOROP)을 적용한 항공용 EO/IR 센서에 대한 기본 개념과 실험실 촬영결과를 제시한다. 이 센서는 대구경광학계, 고감도 검출기, 영상처리, 영상형성을 위한 서보메카니즘 등으로 구성된다. 표적영상은 광학계를 통하여 검출기에 집속되며, 검출기 출력신호는 카메라를 구동하는 서보메카니즘과 영상처리 기법을 통해 고분해능 영상을 형성하게 된다. 서보 메카니즘은 항공기 탑재 환경에 대응하여 진동을 차단하고 자세변화를 보상하여 안정된 영상이 촬영되도록 할 뿐만아니라 항공기의 이동에 따른 영상 품질저하를 방지하여 효율적인 영상 촬영기법이 가능하게 한다. 설계, 제작된 센서는 항공기 탑재 및 장거리 표적 환경을 반영한 실험실에서 영상을 촬영한 결과 우수한 영상이 획득되었다. The purpose of this paper is to introduce an airborne EO/IR sensor for the long range oblique photography(LOROP) which photographs target area at long distance with sidelooking pattern. This camera consists of several technologies, such as large aperature optics, senstive detectors, image processors and image forming servo mechnism. The target image is focused on a detector through optics and then the detected signal is processed to generate photography with help of image forming servo mechanism. While the airplane is moving and to take wide area photograph, electro-mechanical step and stare mechanism is necessary.

Leucine-C¹⁴에 依한 Puromycin이 白鼠顎下腺의 蛋白合成에 미치는 影響에 關한 自記放射法的硏究

許濬 최신의학사 1971 最新醫學 Vol.14 No.11

Male Balb C/Strain were used in all experiment. They ranged in weight from 18 to 23 gm. Puromycin dihydrochloride was injected intraperitoneally in aqueous solution, in a concentration of 2mg. /ml. , which had been neutralized with naoh. Two doses of 80mg/kg body weight each were given on day 1 intervals. Following the last injection, 3 pairs each were sacrificed on days 4, 6, 10 and 15. Thirty minutes prior to sacrifice 49c/gm body weight of leucine-C" (Specific Activity 278mc/mM) were injected. For the light microscopic studies, tissue were fixed 2% paraformaldehyde and sections were stained with toluidine blue o. The purpose of the present study was to determine, by means of quantitative autoradiography, the effect of puromycin on the protein synthesis of submandibular gland cells. 1. Following administration of puromycin to mice for 10 days, many of the acinar cells are lack the normal basophilia, increase of the vacuoles and the nuclear pyknosis. 2. We have observed that the protein synthesis as expressed by the incorporation of leucine-C" into submandibular gland cells is suppressed during first 4 days after the puromycin injections, but was significantly suppressed by 10 days. The grain number in puromycin-treated animals increased to a level similar to that of the controls by 15 days. 3. It is concluded that the synthesis of overall cytoplasmic proteins is temporarily impaired after puro-?mycin injections in submandibular gland cells of mice.

The malolactic fermentation (MLF), which is widely used in winemaking, is the conversion of malic acid to lactic acid conducted by the malolactic enzyme (Mle) of lactic acid bacteria. In order to select the strains with MLF among 54 lactic acid bacteria isolated from the traditionally fermented foods, we designed a primer set that specifically targets the conserved regions of the mle gene and then selected four strains that harbor the mle gene of Lactobacillus plantarum. All strains were identified as L. plantarum by analyzing the 16S rRNA sequences, biochemical properties, and the PCR products of the recA gene. From comparison of the mle gene sequences consisting of 1,644 bp, the nucleotide and amino acid sequence of strain JBE60 correspond to 96.7% and 99.5% with those of other three strains, respectively. The strain JBE60 showed the highest resistant against 10% (v/v) ethanol among the strains. The strains lowered the concentration of malic acid to average 43%. Considering the ethanol resistance and conversion of malic acid, the strain JBE60 is considered as a potential starter for the malolactic fermentation.

In this paper, we analyze a planar electromagnetic absorber by using the mode matching technique(MMT). The proposed electromagnetic absorber has a periodic structure composed of a perfect conductor and ferrite, and the transmitted and reflected powers in response to the incident wave with parallel polarization are calculated according to the thickness of the plate. The proposed absorber shows a high absorption compared to the cases of periodic slits with vacuum or the ferrite plate itself. The solution to the reflected and transmitted powers by MMT is also verified with the results from a commercial simulator.
