일정 열속으로 하부면이 가열되는 수평 유체층에서 열적 불안정성 해석

이종대,최창균,신치범 한국화학공학회 1988 Korean Chemical Engineering Research(HWAHAK KONGHA Vol.26 No.3

초기에 정지되어 있는 수평 유체층의 하부면을 일정한 열속으로 가열할 때 자연대류의 유발시점을, 전파이론을 근거로, 해석하였다. Deep-pool계에 대하여 기본온도분포를 적분방법에 의하여 모사하고 새로운 안정성 방정식을 유도하였다. Prandtl수가 매우 큰 경우, 임계조건들을 구하여 아래와 같은 상관식을 얻었다. τ_c = 4.57 Ra^½ 이는 기존실험치들과 Ra>10⁴인 범위에서 잘 일치함을 보여 주었다. 또한 발생되는 자연대류는 4τ_c에 감지될 정도로 증폭되는 것으로 나타났다. When an initially quiescent, horizontal fluid layer is heated uniformly from below, the critical time of the onset of natural convection is analysed by employing the propagation theory. For deep-pool systems the basic temperature profile is approximated by using the integral method and a new stability equation is generated. The critical conditions are found to have following relation: τ_c = 4.57 Ra^(-½) for Pr →∞ This relation agrees well with experimental data in the range of Ra >10⁴. Also, it is seen that the initiated convection is amplified to observable magnitude at the time 4 τ_c.

In this study, Silicon and petroleum pitch were coated on the surface of Si/C fiber manufactured using electrospinning to improve the electrochemical performances. SiO2/PAN fiber was prepared by electrospinning with TEOS and PAN at various ratios dissolved in DMF. The characteristics of carbonization, reduction, and pitch coating processes were investigated for the optimal process of the pitch coated Si/C fiber anode composite. Anode composite prepared with TEOS/PAN = 4/6 (CR-46) after carbonization and reduction process has a capacity of 657 mAh/g. To improve capacity and stability, Si powder and PFO pitch were coated at the surface of CR-46. When the pitch composition was fixed at 10 wt%, it was found that the capacity increased as the weight ratio of silicon increased, but the stability decreased. The pitch coated Si/C fiber composite with 10 wt% silicon has high capacity of 982.4 mAh/g and capacity retention of 86.1%. In the test to evaluate rate performance, the rate capability was 80.2% (5C/0.1C).

Phobic postural vertigo is characterized by nonrotational vertigo with postural and gait instability, and mainly occurs in people who have an obsessive-compulsive personality. The condition often begins after a stress, a physical illness, or vestibular insults. The most important therapy consists of psycho-educative explanation and self- controlled desensitization.

In the mid of 1930 endemic mottled enamel were reported to occur in the two different hotspring areas, one at Chu-Ul hotspring in Hamgyung-Pukdo, and the other at Mt. Diamond's hotspring in Kangwondo. Recently another report has been made by Dr. Paik that there is a prevailing incidence of dental fluorosis in school children at Yoosong hotspring town, Chungcheong-Namdo. The authors conducted an epidemiological study at the area in order to find out the endemicity of disease, the prevalence of dental caries in relation to the etiological implications with fluorine-bearing drinking water. The survey period for dental enamel and dental caries was from l~15 April, 1963 and a total of 942 children of Yoosong primary school (503 males and 439 females) received the examination. Fluorcsis indices were calculated with the severity of affection using the Dean's classification. Chemical analysis was made of water samples taken from 44 drinking wells of the survey villages, which are the only water supply resources for the villagers. The amount of fluorine content was measured with the zirconium-alizarin method plus photoelectric color comparison known as the Megregian-Maier method. The followings are the result of the study: 1. The dental fluorosis rates of school children at Yoosong Myon were 46.8% for both sexes, 45.7% for male and 48.5% for female. The age range of high incidence was 11 years of age, which showed 51.8%. 2. The prevalence of fluorosis varied with village and high incidence was noted in villages of Pogmyong-Ri, Oun-Ri, Kapdong-Ri, Chookdong-Ri and Changdae-Ri as shown 51.0~65.0%, while the villages of Noun-Ri, Koongdong-Ri, Pokyong-Ri and Chizok-Ri showed as low as 31.6~35.6%. 3. The fluorine content of the well waters ranged from nil to as high as 4.6ppm. The well waters of Pongmyong-Ri, where showed the highest incidence of fluorosis in children, contained the highest amount of fluorine. On the contrary, the wells of Kooam-Ri, having the lowest prevalence contained as low as 0.2 ppm of fluorine. 4. The relation of dental fluorosis to dental caries is characterized with the fact, the higher fluorosis rate, the lesser prevalence of caries. This was seen in both the deciduous and permanent teeth. 5. The average df rate of school children was 55.4%, the DMF rate was 16.6% and thus the total dental caries rate (df plus DMF) averaged 37.5%.

In Dae Jeon Eul-Ji General Hospital, activated since 1581, 54 patients with Korean Hemorrhagic Fever Who were all positive for Korea antigen were observed from January, 1981 to December, 1984. Epidemiology, clinical features, laboratory findings, complications and clinical course in Korean Hemorrhagic Fever were analyzed. The results were as follows: 1. The most prevalent area was OK-Chun Kun. 2. The peak incidence of age was fifth decade and male to female ratio was 2:1. 3. The peak incidence was November to December. 4. The most frequent symptomes were epigastric pain, nausea and vomiting and followed by hemsturia. 5. Conservative treatment was done and hemodialysis was performed in 19 patients without death.

정부출연 연구기관의 성과관리시스템 구축 및 운영 사례연구

이종대,정양헌 한국회계정책학회 2012 회계와 정책연구 Vol.17 No.2

This study examines a case in that performance management system (PMS) development of a national research institute can be analyzed. We set a case study framework with that several observable points (Goal-Plan-Action) can be identified. A national research institute (Institute A), a well-known long time high performer, has implemented three distinct PMS during past seven years. PMS before 2005 (PMS 1) was an evaluation oriented system (Goal) with many qualitative performance measures, was mainly used to rank employees according to their scores (Plan), and was a lack of sufficient communication tools to set KPI goals and to get feedback performance information (Action). PMS 2 based on the BSC concepts was implemented to effectively manage strategies execution (Goal) by aligning KPIs (Plan) and facilitating participations in setting KPI goals, monitoring, and getting feedback information (Action). PMS 3 was built to lessen the avoidable competition and tension among employees (Goal), to provide selective KPIs so that employees made more suitable KPI sets for them, and to make managers have rights and responsibilities to manage their own optimal results. Institute A has successfully managed performance with the integration of PMS 2 of effective strategies executions into PMS 3 of user-oriented performance systems. 본 사례연구의 목적은 정부출연 연구기관 중 다년간 기관평가 결과가 우수한 A연구원을 선정하여 성과관리시스템(Performance Management System)을 도입하여 운영해가면서 이를 지속적으로 고도화하는 과정을 분석하는 데 있다. 본 사례연구는 목표(Goal), 계획(Plan), 운영(Action)의 관찰관점을 설정하고 성과관리시스템이 이들 관찰관점을 중심으로 어떻게 변화해 왔는지를 분석하였다. A 연구원의 성과관리시스템을 분석한 결과 (1)정성평가가 주를 이루고 있는 2005년 이전(성과관리시스템 1:PMS 1)과 (2)성과중심평가가 정착된 2005년에서 2008년(성과관리시스템 2 :PMS 2), 그리고 (3)자율적 성과기반평가 체계를 도입하는 2009년 이후(성과관리시스템 3:PMS 3)의 3단계로 나누어 살펴보았다. PMS 1 시스템은 정부시책에 부응하는 출연연구원으로 성과구현에 관해서는 피동적이었고(Goal) 성과평가시스템은 정성적 태도중심으로 평가를 하고 평가항목 설정에 관한 협의나 토의는 없거나 미미한 것으로 판단되며(Plan) 성과평가는 서열을 정하기 위해 정성적 태도평가가 중심이어서 성과정보의 환류는 기대하기 어려웠다(Action). PMS 2 시스템은 기관의 전략을 달성하기 위한 개인 및 팀의 업무 정렬(Goal)이 목표이었고, 연구부서 성과 지표의 단순화와 협업 강조와 지원부서의 가치창출을 위한 목표 설정(Plan) 그리고 모니터링 및 피드백 활동 강화(Action)이었다. 성과시스템 재구축을 통하여 논문이 양적 및 질적으로 발전하였으며 특허, 기술거래의 양적인 성장세가 두드러지고 적극적인 연구성과를 홍보하여 연구원의 존재감이 향상된 것으로 파악되고 있다. PMS 3 시스템은 PMS 2의 지나치게 경직된 정량지표가 강조(Plan)되고, 모니터링에 있어 중요한 소통 및 피드백이 부족(Action)하고 무엇보다도 부서장의 리더십 발휘기능이 부족(Goal)한 단점을 개선하기 위하여 독립평가와 선택적평가 도입(Plan), 부서장 권한강화와 피드백 강화(Action)가 도입되었다. PMS 3의 성과는 PMS 2의 전략목표 달성을 위한 전략 실행 도구의 역할을 유지하면서 지속적인 개선과 아울러 구성원 만족도를 개선하고 있다.
