단일약국과 다약국 프로그램에서 수행한 지역약국 필수실무실습에 대한 평가
이민철,조민휘,정영준,이지영,윤현옥 한국임상약학회 2014 한국임상약학회지 Vol.24 No.4
Background: The first pharmacy student practice undergoing 6 year pharmacy school curriculum have begun in thehospital pharmacy, community pharmacy, pharmaceutical company and administrative office since 2013. Although mostof practice sites have prepared the program of pharmacy student practice education for several years under guideline ofKorean Association of Pharmacy Education, generally community pharmacies which start the pharmacy student practiceeducation have difficulty in performing the desirable student practice program due to absent experience for it. Sowe reported the comparison of student practice programs between mono pharmacy and multiple pharmacies conductedby Gyeongsang National University College of Pharmacy to provide the future design information of the ideal pharmacystudent practice in community pharmacy. Method: Students who practiced both multiple (multi) and mono pharmacy(mono) programs for each 5 weeks were participated the survey to evaluate the student practice programs. Results: The results of the survey on the student practice program reported that students were much more satisfied with themultiple pharmacies program than mono pharmacy program in both practical contents (4.12± 0.72 : 3.27±1.28; multi : mono)and satisfaction (4.54±0.54 : 3.54±1.3; multi : mono) and they all gave the highest points (5.00±0.00) to multiple pharmaciesprogram for recommendation because the multiple pharmacies program was significantly helpful for their experienceto plan the future career. Conclusion: Mono and multiple pharmacy practice programs would be a great helpfulfor student’s future career. However, the disadvantages of each program should be amended gradually for the unifiedand specialized program to be established the ideal community pharmacy student practice in Korea. The results will beaffected the pharmacy practice program for students in community pharmacy and the other colleges of pharmacy todesign the ideal community pharmacy practice program.
신연료 DME의 복합화력발전소 적용을 위한 연소성능시험
이민철(Min Chul Lee),서석빈(Seok Bin Seo),정재화(Jae Hwa Jung),안달홍(Dal Hong Ahn) 대한기계학회 2006 대한기계학회 춘추학술대회 Vol.2006 No.6
Recently, DME(Dimethyl Ether, CH3OCH3) has highly attracted attention as an alternative fuel because of its easy transportation and clean characteristics. This study was conducted to verify the combustion performance and to find troubles when DME is fuelled to a gas turbine. Combustion tests were conducted by comparing DME with methane, which is a main component of natural gas, in aspects of combustion instability, NOx and CO emission and the outlet temperature of combustion chamber. The results of performance tests show that DME is a very clean but hard to control. CO emission level of DME is lower than that of methane and NOx emission level of DME is as low as that of methane. When firing DME, the pressure fluctuation in combustion chamber caused by combustion instability is lower than that of firing methane. From the result of outlet temperature, we can get DME is easy to flash back, and this property should be considered when operating a gas turbine and designing a burner.
Preparation of carbon aerogel derived from resorcinol-formaldehyde for electrode materials
이민철,홍창국 한국공업화학회 2014 한국공업화학회 연구논문 초록집 Vol.2014 No.1
Carbon aerogels were prepared by polycondensation of resorcinol with formaldehyde using sodium carbonate as a catalyst in ambient conditions, and they were used as an electrode of electrical double-layer capacitor. As a general trend, the ability of the electrodes to electrosorb ions depended on the microporosity, whereas the large pores (mesopores) had a strong influence on the kinetics of the electrosorption process. In this paper, the effect of resorcinol to catalyst ratio (R/C ratio) on pore size distribution, BET surface area, and electrochemical property of carbon aerogels was investigated by changing R/C ratio from 500 to 1500. In order to minimize volume shrinkage, solvent exchange was performed with acetone at 50°C for 5 day. Carbon aerogel prepared at R/C ratio of 800 showed the highest BET surface area with average pore diameter of 7.9 nm. The morphology of carbon aerogel was investigated using SEM. The surface area and pore size were measured by BET.
Intercalation of graphene oxide in functionalized bio-based composite materials from soybean oils
이민철,홍창국 한국공업화학회 2014 한국공업화학회 연구논문 초록집 Vol.2014 No.1
The Bio based resin is renewable and inexpensive natural materials to replace the petroleum based polymers. Graphene has attracted significant attention recent years. Because Ideal structured graphene has better properties than conventional filler materials for polymer composites. Chemical oxidation is effective method for mass production of graphene. Graphene oxide(GO) is an useful intermediate in chemical oxidation method. GO contains several functional groups such as hydroxyl, carboxyl, and epoxy groups. Therefore, GO can be well dispersed in water due to its hydrophilic properties. Acrylated epoxided soybean oil was introduced hydrophilic functionality through malenization reaction. Maleization reaction was confirmed by FT-IR. It is important reaction for intercalation of GO in resin. The interlayer of GO was measured through X-ray diffraction (XRD). Graphene-filled polymer composites was confirmed by TEM. Mechanical property of Graphene-filled polymer composites was enhanced by increasing the interlayer of GO in resin.
