정재명 ( Jae Myung Jung ) 한국지방행정연구원 2016 地方行政硏究 Vol.30 No.1

본 연구에서는 69개 일선구청의 대민 행정서비스 생산에 대한 단년도의 효율성을 초효율성 모형을 활용해 측정했으며, Malmquist 생산성 지수를 이용해 다년간의 생산성 변화율을 측정하고 그에 대한 시사점을 제시하고자 하였다. 연구결과 기술효율성 전체 평균은 1.2072로 나타났으며, 이중 부산중구청과 서울중구청이 가장 효율성이 높은 구청으로 나타났다. 규모수익체증을 나타내는 구청은 28개로 전체의 40.6%를 차지했고, 규모수익체감의 영역에 속하는 구청은 41개였다. 생산성 지수는 연평균 0.69% 증가한 것으로 나타났으며, 세부내용에서는 기술효율성 변화율과 순기술효율성 변화율, 그리고 규모효율성 변화율, 기술변화율 모두에서 당해기간 동안 거의 변화가 없었다. 각 구청 생산성지수의 시기별 변화율 추이를 보면, 생산성이 증가한 구청은 18개 구청인 반면, 23개 구청에서 생산성의 하락이 있었다. This research aims to measure the efficiency of 69 district offices in 7 Metropolitan governments of 2013 year and further evaluate their productivity growth during the period of 2008-2013, using the Super Efficiency Measure(SEM) and Malmquist Productivity Index(MPI). The results show that the average efficiency score of the 69 district offices is 1.2072; and the most efficient district offices among them are the Busan and Seoul Jung-gu District Offices. The number of the district offices to be included to Increasing Return to Scale(IRS) is 28(40.6%) of the 69 district offices; whereas the number of Decreasing Return to Scale(DRS) is 41 district offices. Second, according to this research, the annual productivity of the 69 district offices increased 0.69%. The efficiency of the annual technological change, SE, and PTE was stable without any change. Furthermore, 18 district offices increased in MPI; whereas 23 decreased.

Background and Purposes: Over the past three decades, numerous studies performed in Korea have reported that job stress is a determinant risk factor for chronic diseases and work disability. Every society has its own culture and occupational climate particular to their organizations, and hence experiences different occupational stress. An occupational stress measurement tool therefore needs to be developed to estimate it objectively. The purpose of this study is to develop and standardize the Korean Occupational Stress Scale (KOSS) which is considered to be unique and specific occupational stressors in Korean employees. Subjects and Methods: Data were obtained from the National Study for Development and Standardization of Occupational Stress (NSDSOS Project: 2002-2004). A total of 12,631 employees from a nationwide sample proportional to the Korean Standard Industrial Classification and the Korean Standard Occupational Classification were administered. The KOSS was developed for 2 years (2002-2004). In the first year, we collected 255 items from the most popular job stress measurement tools such as JCQ, ERI, NIOSH and OSI, and 44 items derived from the a qualitative study (depth interview). Forty-three items of KOSS, in the second year, were retained for use in the final version of the KOSS by using Delphi and factor analysis. Items were scored using conventional 1-2-3-4 Likert scores for the response categories. Results: We developed eight subscales by using factor analysis and validation process: physical environment (3 items), job demand (8 items), insufficient job control (5 items), interpersonal conflict (4 items), job insecurity (6 items), organizational system (7 items), lack of reward (6 items), and occupational climate (4 items). Together they explained 50.0% of total variance. Internal consistency alpha scores were ranged from 0.51 to 0.82. Twenty-four items of the short form of the KOSS (KOSS-SF) were also developed to estimate job stress in the work setting. Because the levels of the subscales of occupational stress were gender dependent, gender-specific standard norms for both the 43-item full version and the 24-item short form using a quartile for the subscales of KOSS were presented. Conclusion: The results of this study suggest that KOSS might be an appropriate measurement scale to estimate occupational stress of Korean employees. Further and more detailed study needs to be conducted to improve the validity of this scale.

As increasing the power demands, we can take the advantage in reduction of power loss, voltage drop, loss of transformers and distribution line, while we use reasonably the energy which is limited by the insufficient supply of energy resources and the high power rates. So industrial field is increasing the facilities of capacitor bank for active power and the reduction of the power loss. This paper improve the working domain by searching the optimal value of Xc in load circuit, as detecting different between voltage phase and current phase which is supplied to load by using PT and CT. Also, this paper can aid learners understand easy Power factor measurement and improving method by using phase relation between voltage and current, compose method of capacitor bank, and processor on the educational field.

Dense Kondo계인 CeTe와 정상금속인 LaTe의 크기 양질인 단결정을 개선된 Bridgeman방법으로 성장시켰다. 이 단결정을 이용하여 0.05∼8eV의 광범위한 에너지 영역에서 반사율을 측정하여, Kramers-Kronig변환을 통해 광학전도도를 얻었다. 광학전도도의 스펙트럼을 분석한 결과, CeTe와 LaTe의 경우 모두 p-d 전이에 의한 두 개의 피크가 3.6eV와 5.1eV에서 발견되었다. 이 두 피크의 형성 mechanism은 5d-band의 입방결정장에 의한 것임을 알았다. 그리고 CeTe의 경우는 LaTe에 없었던 4f-5d전이에 의한 피크가 0.4eV에서 발견되었다. 이는 XPS 스펙트럼으로부터 얻은 bare 4f-전자의 binding 에너지(약 1.5eV)에 비해 매우 작은 값이다. 이 편차는 local field를 고려한 Lorentz모델을 적용함으로서 잘 설명되었다. 또한, localization의 정도로 약 0.4의 값을 얻었다. 끝으로, 띠내전이의 해석으로부터 LaTe의 경우보다 CeTe의 경우가 전도전자의 유효질량이 무겁다는 사실을 얻었다. 이것으로부터 CeTe의 여기상태인 Γ_8와 전도전자 간의 Kondo 교환상호작용의 에너지가 매우 크다는 것을 알았다. We had grown the high quality single crystals of dense Kondo system CeTe and normal metal LaTe by using the advanced Bridgeman method. The reflectivities of the single crystals were measured in wide energy range from 0.05 to 8eV, and their optical conductivities were obtained using Kramers-Kronig transformation. By the result of their optical conductivity spectra, two peaks due to p-d transition were discovered at about 3.6 and 5.1eV, respectively. The double peaks were explained by cubic crystalline electric field. And in case of CeTe, extraordinary peak due to f-d transition, which LaTe had not, was appeared around 0.4eV. This value was well explained by the Lorentz model considering the local field. The degree of screening due to conduction electrons was evaluated to be about 0.4. The effective mass of conduction electron of CeTe was large compared with that of LaTe. From this, we could obtain the fact that in CeTe, Kondo exchange energy between conduction electron and excited Γ_8 state was very large

Scopolamine and hyoscyamine which belong to tropane alkaloids are the pharmaceutically valuable anticholinergic drugs. In order to increase the productivities, the effects of elicitation were investigated during hairy root cultures of Scopolia parviflora. Biotic elicitors originated from 3 fungi and 1 yeast were prepared as homogenate and supernatant and added to 3-week-old cultures. Both of homogenate and supernatant of Candida albicans elicitors increased the scopolamine production. The production of hyoscyamine was enhanced by homogenate of Fusarium solani and supematant of C. albicans. Most of the other fungal elicitors were also improved on the tropane alkaloid production compared to non-treatment. Among the elicitors tested, C. albicans was proved the optimal biotic elicitor on tropane alkaloids production. These results will be served mass production of tropane alkaloids by large-scale production.

A numerical study was performed to investigate characteristics of one-dimensional consolidation of soft clay. Results of consolidation tests with the remolded normally consolidation clay of having a very high initial void ratio were analyzed by using the numerical technique of finite difference method based on the finite strain consolidation theory, to evaluate consolidational characteristics of soft clay under surcharges on the top of clay. On the other hand, a numerical parametric study on soft clay consolidated due to its self-weight was also carried out to find its effect on one-dimensional consolidation. Terzaghi's conventional consolidation theory, finite strain consolidation theories with linear and non-linear interpolation of effective stress-void ratio -permeability realtion were used to analyze the test results and their results were compared to each other to figure out the difference between them.Therefore, the validity of theories was assessed.

Postpartum hemorrhage remains one of the leading causes of maternal deaths. The major causes of postpartum hemorrhage include uterine atony, retained placental fragment, placenta accreta, and lower genital tract lacerations. Conservative treatment is based on administration of uterotonic drugs, vaginal packing, and surgical repair of genital tract lacerations. When bleeding fails to respond to conservative treatment, surgical ligation of uterine vessels or hemostatic hysterectomy is performed. We present a case of postpartum bleeding treated by selective uterine arterial embolization with a brief review of previous literatures of postpartum hemorrhage & uterine arterial embolization.
