박정근,문규,위재경,Park, Jung-Keun,Moon, Gyu,Wee, Jae-Kyung 대한전자공학회 2004 電子工學會論文誌-SD (Semiconductor and devices) Vol.41 No.4

고속 저전력 디지털 시스템을 위해 클록 스큐를 최소화하고 동적 파워 소모를 줄이는 새로운 클록 분배 방법을 제안하였다. 제안된 방법은 접힌 라인구조(FCL)과 위상 섞임 회로(phase blending circuit)을 이용하여 Zero-skew 특성을 갖는다. FCL에 적합한 라인 구조를 분석하기 위해, 마이크로 스트립과 코플라너 라인을 FCL형 클록 라인으로 분배되었다. 시뮬레이션 결과는 l0㎜ 떨어져 있는 두 리시버 사이의 최대 클록 스큐가 1㎓에서 10psec보다 적고 20㎜ 떨어져 있는 두 리시버 사이의 최대 클록 스큐는 1㎓에서 60 psec보다 작음을 보였다. 또한, 공정, 전압, 온도 변화에 무관하게 클록 신호들의 스큐가 변하지 않음을 알 수 있었다. A novol clock distribution scheme is proposed for high-speed and low-power digital system to minimize clock skew and reduce dynamic power consumption. This scheme has ideal zero-skew characteristic by using folded clock lines (FCL) and phase blending circuit. For analyzing suitable line structures to FCLs, microstrip line and coplanar line are placed with folded clock lines. Simulation results show that the maximum clock-skew between two receivers located 10mm apart is less than lops at 1㎓ and the maximum clock-skew between two receivers located 20mm apart is less than 60ps at 1㎓. Also the results show that the minimum skews of clock signals regardless of process, voltage, and temperature variation are invariant.

The data used in this study was set as key values for data collected at the university in 2020 at S University, as data that could be combined as key values for school numbers. Multiple regression analysis of academic performance as a dependent variable was carried out in the success factors of the students who are dependent variables. The key abilities affecting academic performance were analyzed to have positive effects in the order of empathy leadership, major ability, conflict resolution ability, multicultural understanding and acceptance ability, community ethical ability, interpersonal ability, and creative problem solving ability. The results showed negative effects on the following: empathy leadership ability, interpersonal relationship ability, moral judgment ability, collaboration ability, total human personality ability, and creative thinking ability. Through decision-making tree analysis which is a data mining technology, the data of the academic interrupter, the rest scholar, and F unit were analyzed, and the discrimination and pattern of the academic performance predictor were analyzed. As a result of the decision-making tree analysis, the first factor is one semester, so students must be intensively controlled for one semester. The results of this study have been suggested as follows: As the dependent variable of the result, the following should be continued: Support of the model, upgrading of the model, enrollment rate, enrollment rate, F unit/holiday/extraception, etc., by setting the concept of success of the student(grades, employment, ability, etc.). Each university has no correct answer to the factors that affect the success of its students, so each university must share a variety of analytical results and obtain benchmarks. This study was analyzed only in 2020, so it is necessary to compare panel analysis with transition analysis for one semester and two semesters every 18, 19 and 20 years. Detailed comparative analysis by groups such as each department, admission type is required to develop strategic establishment/programs of universities and departments.

Musculoskeletal disorder (MSD) problems have been increasingly reported in hospital sector but the problems were not addressed with respect to holistic aspects of the target population in Korea. Often, it is required to understand how MSD symptoms are associated with factors such as personal, work environmental and psychosocial stressors. To examine features of association between sets of MSD symptoms and the factors, a questionnaire survey was conducted in a university hospital. A 140-item questionnaire was developed and used for collecting information including factors (e.g., job/occupation, task/activity, job stress) and MSD symptoms. A total of 1,091 workers (male 23.7% and female 76.3%) were finally determined for data analyses. Prevalence rate for the whole body was 72% and, among body parts, the highest was 48.7% for the shoulder, followed by 34.6%(the low back), 32.7%(the leg/foot), 27.9%(the neck), 26.7%(the wrist) and 12%(the elbow). The symptoms were significantly different by job/occupational variable in each of all body parts except the neck. The symptoms were very significantly different by task/activity variables in each of all body parts while those symptoms were significantly different by psychosocial variables, depending on body part and gender. In the logistic regression analyses performed for MSD symptoms by body part and each of 3 factors, odds ratio values varied, ranging from 0.7 to 3.3. The controls for reducing the symptoms were discussed on the basis of the findings. The results show that the MSD symptoms can remarkably vary by the factors and, in particular, can be highly differential for the task/activity factor. This study suggests that MSD symptom features be examined by using various factors and then a higher differential factor be primarily utilized for controling MSD symptoms in general industry including hospital settings.

N/A One of the new situation of national agricultural system is the importance of diversity and complexity in the funding and execution of agricultural research. In order to be responsive to rapid changes of economic conditions agricultural research institutes should strengthen efficient and flexible research systems. All research organization increasingly requires an institution capacity for monitoring and evaluation system. Determination of the relative contribution of the development of social science research capacity to work on institutional innovation is clearly central to improve research personnel allocation.

이 연구는 1981년 이후 우리나라 원예생산의 산출, 투입 및 생산성 변화추이와 성장률을 계측하여 부문별 및 기술별 연구자원 배분의 효율성을 분석하였다. 이 분석결과는 앞으로 원예부문 연구자들의 연구 방향설정과 원예 관련 연구정책 수립에 활용될 수 있을 것이다. 1981-2002년 기간의 원예분야 생산의 성장은 연평균 4.44%의 비교적 높은 성장을 보였다. 그러나 성장은 생산성보다 투입물의 증가에 의하여 이루어졌다. 1990년대 중반 이후 이와 같은 경향은 더욱 뚜렷하게 나타나 1990-2002년 기간의 투입물의 성장에 대한 기여는 79.60%임에 반하여 생산성의 성장에 대한 기여는 20.40%에 불과하였다. 원예분야의 성장에서 채소와 과수부문은 투입의 증가보다 생산성 증가에 의하여 이루어졌다. 그러나 화훼는 높은 산출의 성장에도 불구하고 생산성의 기여는 거의 나타나지 않고 투입물의 증가에 의하여 이루어졌다. 원예분야의 연구자원 배분은 부문별 연구자원 배분과 경제적 연구 성과가 비교적 높은 일치성(0.910)을 보이나 기술별 연구자원 배분의 일치성(0.826)은 상대적으로 품목에 비하여 낮게 나타났다. 부문별 연구자원 배분보다 기술별 연구자원 배분의 효율성이 상대적으로 낮아 원예분야의 기술별 연구자원 배분과 연구관리의 효율성을 높여야 할 것이다. 특히 육종기술의 경제적 성과가 재배기술보다 낮아 앞으로 육종기술에 대한 연구자원 배분의 합리성을 도모하여야 할 것이다. This study estimated the growth rates of output, input and total factor productivity in horticulture and analyzed efficiency and priority setting for horticulture research resource allocation by the congruency index and scoring method. Over the whole period of 1981 to 2002, the average annual compound rate of output had been 4.44 percent while total input and total factor productivity had grown at an average rate of 1.69 and 2.71 percent, respectively. The consistency index of budget distribution of the RDA research on horticulture by product was estimated as 0.910. This means that the allocation is efficiently made in the research resources of horticulture. However, in terms of the index by technique it was 0.826 and lower than that by the product. The improvement of the research resource allocation by technique would be required in horticulture.
