Synthesis and Characterization of Cathode Materials for the Lithium Secondary Batteries by Spray Drying Method

오시형,정운태,조원일,조병원 한국전기화학회 2005 한국전기화학회지 Vol.8 No.1

It has been known that the synthesis of the cathode materials for the lithium rechargeable batteries by the sol-gel process has many advantages over the conventional solid-state method. It has been, however, a continuing issue that new additional steps should be introduced to commercialize this process. In this work, spray drying was introduced to the existing sol-gel process as a continuous mass production method of the pre-heat treatment precursor materials. The precursors of LiCoO2 and Li Ni0.8Co0.2O2 were continuously produced through spray drying from the solution containing stoichiometric amount of lithium, cobalt, and nickel sources as well as a chelating agent. The process variables, such as pH of the starting solution, spray drying conditions, and calcination conditions were optimized. The XRD pattern for the synthesized material indicated a good crystallinity with a layered structure.

2010 school year school consulting begins to make a help for school community which want to resolve the problems in school administering and educational problems. Consultants study about the questionnaire of school culture, school curriculum plan, school evaluation report by the school itself, school evaluation report by regional school district of education government, questionnaire in school evaluation report, school home-page, school infomation opened by on-line and so on. And then consulting was done by professors, school master, officer of education government, researcher. As we find some results through this case study, school consulting may help to find the solution of educational problems that school masters and teachers confront at schools. This case study show us that many school get a solution for raising the school teachers participation to make a school curriculum plan, making a special school project according to regional and educational environments, raising the ability of behind students in learning. 2010학년도 학교 컨설팅은 학교 구성원들이 스스로 학교 경영 및 교육 개선 과제를 해결해 나갈 수 있도록 지원하고자 하는 의도에서 출발했다. 학교 컨설팅은 컨설팅 대상학교에서 의뢰한 과제와 컨설턴트가 학교 자료를 분석해 도출한 문제를 가지고 의견조율을 통해 결정한 후. 컨설팅 의뢰 학교가 보내준 학교조직문화진단지, 학교 교육계획서, 학교 자체 평가보고서, 학교 평가 자료, 학교 평가 수행시 조사된 만족도 조사 설문 결과, 기타 학교 관련 자료 등과 학교 홈페이지, 학교 알리미를 통해 공시된 정보를 컨설턴트들이 살핀 후에 수행되었다. 이 연구에서 알 수 있듯이 학교 컨설팅을 통해 학교 교육 과정 운영 계획을 수립함에 있어 교사들의 참여 제고 방안, 지역 여건에 적합한 학교 특색 교육 운영 계획 수립, 기초 학력 미달 학생의 학력을 향상 방안 등을 찾을 수 있었다. 앞으로 학교 컨설팅이 더욱 확대되어 지속적으로 이루어진다면 학교 현장의 교육경쟁력 강화에 많은 도움이 될 것으로 생각한다.

This is a 10 year follow -up study of protest prone college students first reported in 1972 by the same author. All of the original seven subjects finished: college, and at present, four are employed in business firms, two are in the United States for Ph.D. w hile one runs a restaurant. In summarizing the lives of these seven students、 since the time of the first study, five stages of life and their meanings can be identified as follow s:(1) Army draft during college-An analysis of these five life stages indicated that the students felt“comfortable and relieved”in the strenuous military enviroment since it was viewed as an expiation of guilt caused by poor academic grade and betrayal of protest comrades, and as well as a form of moratorium . (2) Return-to-college after military service-Back in college, they felt like an “outsider” and thus, excluded themselves from extracurricular and pro-test movement activities. Instead, a great amount of their free time was spent at the United States Cultural Center. (3) Employment-All but two got jobs despite their wish to continue studying. The subjects adjustment at work was excellent since the job was viewed as an altern ate form of“patriotism ”. (4) Life in the United States-The students’long wished for dream of going to the U.S. became a reality as they were sent overseas by their respective companies. Yet, their experience in the U.S. was that of frustration mainly due to feelings of inferiority for being Korean. (5) Returning to Korea-Upon returning to Korea they felt depressed and critical of Koreaness, but gradually got over the “Homecoming Syndrome” and became well adjusted in the Korean culture. A long with these findings, five major psychosocial dynamics emerged as follows: (1) Relationship with parents-The so called “Era of Fatherlessness:’ was not observed in the sample. The core value of the father appeared to have been well inherited by the students although their formal value system differed from their father’s. The emotional stability is largely owed to the intimate Irationship with one’s mother who has been all giving and accepting. (2) Transform ation and adjustm ent-Despite the subjects life history, none of them experienced “identity diffusion syndrome” as expected. This seem ed largely due to the well developed compar- tmentalization as a major defense and strong emotional support from family members. (3) Problem of subjecthood-The problem faced by the students was not in establishing identity but in subjecthod which can be divided into two com-ponents-sefhood and social committments. The latter seemed intact in the from of patriotism , however, selfhood as a form of“historical disocation” appeared doubtful. (4) Independence versus groupism -The subjects appeared extremely dependent on groups (i.e., home town group, alumni association, peer group, etc.) while maintaing a sociably responsible position at the same time, thus being labeled as a“social adult and psychological child”. In relating to a group, the studen ts‘ interpersonal style w as characterized by “Eung-Suk”, literally meaning childish clinging. (5) Style of psychosocial m oratorium -unlike the new style evident in postindustrial society, the moratorium style was out of the one; Among the aforem entioned findings, the maintenance of“double conscioussness” in order to achieve some semblance of equilibrium between inertia and flux was most characteristic. For example, independent yet dependent on grouds, logical and scientific yet romantic and sentimental, westernized yet conservative, and idealistic yet realistic. Many Korean youths are perhaps like the sujects of this study and yet the difference lies in the fact that the subjects are aware and critical of their double consciousness where as the youths in general are not.

On the basis of the data from 574 litters of Landrace × Large white × Duroc breeds farrowde at sanji Swine Farm were statistically analysed by least squares method to compare the reproductive performance of mating types, parity and calving season. D × LYD has the best performance in the litter size at birth and the litter at weaning and number of pigs weaned were higher than other mating types(P<0.05). Compare to the reproductive performance by parity, the litter size at birth, letter size at weaning and number of pigs weaned of parity was lower than other parities(P<0.05). Compare to the reproductive performance by calving season the letter size at birth, letter size at weaning and number of pigs weaned were lowest in summer season(P<0.05).

직장체육 프로그램 모형개발에 관한 연구

The purpose the study was to introduce a model program for employee health promotion program in Korea. Employee fitness and health program has been developed by large corporation where the health status is crucial for employer's profit. Unhealthy employee requires extra medical coverage and expenses for an employer so that reducing such a medical costs and helping employees to maintain his or her fitness is the most important task for the human resource department. Korean companies also showed a significant interests in employees' wellness and overall welfare program recently. It is because that the level of employee fitness and health significantly related to productivity and job satisfaction as well as job performance among large corporations. As considering the specific circumstances of Korean economy and structural characteristics, a model program should be proposed with cuations. The fundamental goal of a worksite health and fitness program should be targeted the population of sedentary workers who might have high level of health risk factors such as coronary artery disease, hypertention, and diabetes. Not only a medical screening, a company, but also, should be able to provide a comprehensive health promotion program including nutrition, stress management, and fitness classes. Employers must set up a strategic plan to deploy employee health promotion program which consist a short term and a long term strategies in terms of implementing and evaluating the program. A carefully planned program must be evaluated in 3~5 years later to measure the effect of the program. Therefore, a long-term budget and plan should be considered for an employee health and fitness program. As compared to U.S., an average return from a program would be at least three fold whatever the company pays for their employee in keeping health by an onsite health program.

Effects of Morin on the Pharmacokinetics of Docetaxel in Rats with 7,12-Dimethylbenz[a]anthracene (DMBA)-induced Mammary Tumors

양시형,Joo H. Lee,Dae Y. Lee,Myung G. Lee,Koon C. Lyuk,So H. Kim 대한약학회 2011 Archives of Pharmacal Research Vol.34 No.10

Docetaxel is a P-glycoprotein (P-gp) substrate and metabolized via cytochrome P450 (CYP) 3A subfamily in rats. Morin is an inhibitor of both CYPs and P-gp. Hence, the effects of morin on the intravenous and oral pharmacokinetics of docetaxel were investigated using 7,12-dimethylbenz[a]anthracene (DMBA)-induced mammary tumor rats (DMBA rats) as an animal model of human breast cancer. Docetaxel was administered intravenously (4 mg/kg) and orally (20 mg/kg) without and with morin (15 mg/kg) in DMBA rats. After the intravenous administration of docetaxel in control and DMBA rats with and without morin, the values of non-renal clearance and area under the plasma concentration-time (AUC) for docetaxel were comparable. Morin did not increase AUC or the absolute oral bioavailability (F) for docetaxel after the oral administration of docetaxel in control and DMBA rats with and without morin. The inhibition of hepatic and intestinal metabolism of docetaxel by morin and/or DMBA and the effect of intestinal P-gp inhibition by morin on the pharmacokinetics of docetaxel did not seem to be considerable in DMBA-induced mammary tumor rats.
