Chin Mo Kim,Sam Jin Kim,Chul Sung Kim IEEE 2010 IEEE transactions on magnetics Vol.46 No.2

<P>FeCr<SUB>2-x</SUB>Al<SUB>x</SUB>S<SUB>4</SUB> ( x=0.1, 0.3, and 0.5) samples were prepared by solid state reaction method. The crystallographic structure and magnetic properties of the fabricated compounds were investigated by X-ray diffraction (XRD), superconducting quantum interference device (SQUID) magnetometer, and Mo¿ssbauer spectroscopy. The crystal structure is determined to be a cubic spinel with the space group of Fd-3m and the lattice constants <I>a</I> <SUB>0</SUB>= 9.998, 10.004, and 10.010 A¿ , respectively. The temperature dependence of magnetization, measured from 5 to 300 K, suggests that FeCr<SUB>2-x</SUB>Al<SUB>x</SUB>S<SUB>4</SUB> (x=0.1, 0.3, and 0.5) samples show ferrimagnetic behavior. The decrease of Ne¿el temperature compared with FeCr<SUB>2</SUB>S<SUB>4</SUB> could be interpreted by weakening of the exchange interaction by substitution of nonmagnetic Al ions. Mo¿ssbauer spectra of FeCr<SUB>2-x</SUB>Al<SUB>x</SUB>S<SUB>4</SUB> ( x= 0.1, 0.3, and 0.5) were obtained at various temperatures ranging from 4.2 to 300 K. Isomer shift values of the samples at various temperatures for FeCr<SUB>2-x</SUB>Al<SUB>x</SUB>S<SUB>4</SUB> (x=0.1 , 0.3, and 0.5) were 0.50 ¿ ¿ ¿ 0.73 mm/s, relative to the Fe metal, which are consistent with the Fe<SUP>2+</SUP> valence state.</P>

The purposes of this study were to analyze the farmer education programs in Korea, and to get implications for further program development. The framework for the analysis was developed through extensive literature review and an inductive method. As a result, eight types of organizations for farmer education, seventeen content domains of programs, five instructional methods, three categories of program participant size, and three categories of program period were derived. The subjects of analysis were 2,483 programs of 173 farmer education organizations. The major findings were as follows: 1) Farmer education programs of Korea were led by government agencies such as national organizations and extension agencies. 2) The content domains of cultivating/raising techniques, improvement of life quality and farmer health care, and information acquisition were relatively highly dealt with. 3) Main contents which were dealt with by each type of farmer education organization were differentiated. 4) In terms of instructional method, a lecture had the highest portion in most contents domains. 5) The portion of the middle size and large size of participants was relatively higher than others. And there are no programs which used one by one teaching method. 6) The portion of programs for 1 day or 3days was relatively higher, and the portion of programs for 2 days was lower.

Acinetobacter species is a non-fermentative aerobic gram-negative coccobacillus that is an important pathogen found in nosocomial infections. Recently, multi-drug resistant Acinetobacter baumannii (MDR-AB) infections have been increasing and pose a serious problem. Most such infections present as bacteremia, pneumonia, or a wound infection; however, CNS infections are very rare. We herein present a case of ventriculitis caused by MDR-AB in a 37-year old man after a neurosurgical intervention. The patient was successfully treated with intrathecal colistimethate.

The standards for diagnosis of each disease was arranged by the diagnostic requirements in the following order : another name, notion of disease, the main point of diagnosis, analyzing and differentiating of disease, analysis of disease, discrimination of disease, prognosis, a way of curing and prescription of disease, disease in western medicine appearing the disease in oriental medicine, documents.

농촌지도공무원의 역량수준 진단

김진모,주대진,길대환 한국농업교육학회 2008 농업교육과 인적자원개발 Vol.40 No.1

이 연구의 목적은 농촌지도공무원들의 역량을 진단하는데 있었다. 이를 위해 김진모(2006)가 제시한 농촌지도공무원의 역량모델을 바탕으로 개별 역량의 정의문을 질문문항으로 개발하였고,이를 전체 농촌지도공무원이 역량에 대한 숙련도 수준을 참고하여 각 문항별로 자신의 수준을 자기평가하도록 하였다. 이 연구의 주요 결과는 다음과 같다. 첫째,우리나라 농촌지도공무원의 역량수준은 개발목표 대비 그리 높은 수준은 아니었다. 따라서 현재의 역량수준을 획기적으로 제고할 수 있는 노력이 조직 및 개인 차원에서 시급히 이루어져야 한다. 오늘 날 농촌지도사업의 성패는 농촌지도공무원의 역량에 따라 좌우된다고 해도 과언이 아니기 때문이다. 둘째,연령과 근무기간이 많아질수록 역량지수는 상대적으로 낮았다. 이는 신규지도사의 선발 이후 전문성을 체계적으로 개발할 수 있는 조직적 차원의 지원이 필요함을 보여준다. 조직적 차원의 지원으로는 계층별로 맞춤화된 다양한 역량강화 방안 등을 고려할 수 있을 것이다. 셋째,역량진단을 통해 우선적으로 강화시켜야 할 역량들은 기초직무 역량군에 속하는 여러 역량들과 전문직무 역량군의 기술/주제 전문성 등이었다. 이러한 역량들을 효과적으로 개발하기 위해서는 정규교육만으로는 한계가 많기 때문에 다양한 형태의 육성방안을 모색해야 한다. 이상의 연구결과가 실제적으로 활용되기 위해서는,우선 농촌지도 공무원의 역량 중심 계충 교육과정을 개발하여 실시해야 한다. 또한,농촌지도공무원의 경력개발 체계를 수립하여 실시하고,이들의 부족한 역량을 강화시켜 줄 수 있는 다양한 방법들을 개발하여 실천하려는 노력이 수반되어야 한다. The purpose of this study was to evaluate the competency levels of rural extension workers in Korea. A survey questionnaire was developed using a Competency Model by Dr. Kim(2006), and a self-test was conducted for all of the extension workers in Korea. Based on the findings of this study, the major conclusions were as follows. First, the competency levels of rural extension workers in Korea were not so high for their development goal. The organizational and personal efforts were urgently made for dramatically raising the present competency level. Second, the higher the age and the working period were, the lower their competency index were. It shows that the organizational support is needed for systematically developing the expertise of rural extension workers after being employed as new rural extension workers. Third, the main competencies that should be first strengthened through competency assessment were several competencies in foundational competency cluster and a subject-matter expertise in technical competency cluster. Various forms of strategies for developing these competencies should be sought because the only formal training is not enough to effectively develop these competencies. To practically utilize the result of this study, the following measures should be taken. First, a competency-based curriculum by position level for rural extension workers was developed and implemented, In addition, career development systems for rural extension workers were set up and carried out, and the efforts to develop and apply the various approaches for their insufficient competencies should be made.

낙동강 유역의 지속가능한 이용을 위한 EMERGY 분석

김진이,손지호,김영진,이석모 한국환경과학회 2000 한국환경과학회지 Vol.9 No.1

An EMERGY analysis of the main energy flows driving the economy of humans and life support systems consists of environmental energies, fuels, and imports, all expressed as solar emjoules. Total EMERGY use(720.0 E20 sej/yr) of the Nakdong River Basin is 96 per cent from imported sources, fuels and goods and services. EMERGY flows from the environment such as rain and geological uplift flux accounted for only 4 percent of total EMERGY use. Consequently, the ratio of outside investment to attracting natural resources was large, like other industrialized areas. EMERGY use per person in the Nakdong River Basin indicates a moderate EMERGY standard of living, even though the indigenous resources are very poor. Population of 6.66 million people in 1996 is already in excess of carrying capacity of the basin. Carrying capacity for steady state based on its renewable sources is only 0.226 million people. EMERGY yield ratio and environment loading ratio were 1.07 and 28.52, respectively. EMERGY sustainability index, a ratio of EMERGY yield ratio to environment loading ratio, is therefore less than one, which is indicative of highly developed consumer oriented economies. This study suggests that the economic structure of the Nakdong River Basin should be transformed from the present industrial structure to the social-economic structure based on an ecological-recycling concept for the sustainable use of the Nakdong River.
