In general, there are many degrees of freedom(DOFs) in industrial robot. So they have many poses of several special end-effector's positions and orientations. For that reason, industrial robots are used in a wide scope of industrial applica-tions such as welding, spray painting, deburring, and so on. In this research, an off-line continuous path planning method based on linear interpolation with parabolic blend is developed. The method safely maintains the constant orientation for base frame and end-effector's path within allowable error and minimizes the number of segments in path. This algorithm may apply to welding and painting in which the orientation is particularly significant. The simulation study of cartesian curve is carried out to show the performance of this algorithm.

Korean, which is classified as a non-structural language, has a simple grammar structure but it has a lot of structural ambiguities in its grammar itself. As the role of extra-grammatical information is much more important than that of grammar rules in the syntactic analysis of Korean, an analysis mechanism is required to check dynamically the grammatical relationship between each of constituents. In this paper, we define the conditional unification the method that selectively performs unifications which are satisfied with some conditions in the unification-based analysis. In order to support this kind of analysis method, we extend the PATRⅡ by adding the various condition check devices. We adopt the tree unification to solve the problem of the DAG unification when we implement the conditional unification. In order to show that our presented method is suitable for Korean analysis, we explain that it can solve difficult problems easily, such as ellipsis and inversion. In addition, we show that it is possible to process the coordinate clause that the predicate of the first clause is omitted in the presented method.

This study was conducted to analyze the morphological characteristics and genetic relationships among 24 species of Gerbera. Most of flower colors were pink. The numerical order of flower color was pink, orange, red, double-colored, and milk-white. Majority of flower types were single or semidouble flowers. A few species were double flowers. Flower diameters were from 7cm to 12cm, showed significant differences compared to other characteristics. Flower stalks were ranged from 55cm to 65cm. Only one species was the shortest as 55cm. The others were similar size as about 65cm. Main annual production yields were between 190 and 400 blossoms. Fifty seven reproducible polymorphic bands from eighty primers were used for analyses of genetic similarity. The genetic similarity of 24 collected Gerberas was largely classified into five groups. The average similarity coefficient was 0.72 ranged from 0.50 to 0.90. The highest similarity coefficient was shown between 'Sardana' with red/white flower color and double flower type, and 'Tamara' with orange flower color and double flower type as 0.90.

This study was designed to distinguish by the characteristic difference and the degree of symptoms such as fatigue, pain, coping to pain, and efficacy on pain, and to offer descriptive data for nursing intervention for improving coping ability to pain along each characteristics of disease in chronic arthritis and systemic lupus erythematosus. The subjects were 135 outpatients in the hospital for rheumatic disease in H-University, Seoul. The data were collected by structural questionnaire, from April 29 to June 29, 1999. The results were that the fatigue score was high in the OA patients while the RA patients and SLE patients experienced middle range of fatigue score, but which was not statistically different. Although the RA patients felt higher pain than other diseases, they have well coped with their pain than the others. In efficacy on pain the SLE patients had higher score than others but all of the disease showed lower score. No statistically significant difference among the three croup was recorded in efficacy on pain. Therefore, pain management in the RA patients was primary nursing intervention because they felt severe pain and have well coped with pain while they had lower pain efficacy score than the others. It is also important that fatigue management and coping strategies on pain for the OA patients and SLE patients are specially supportive in the nursing intervention.

OPTIMAL LAUNCHING-INTENTION-AWARE CONTROL STRATEGY FOR AUTOMATED CLUTCH ENGAGEMENT

Yi-yong Yang,Zao-bei Zhu,Xiang-yu Wang,Zheng Chen,Zi-lin Ma 한국자동차공학회 2017 International journal of automotive technology Vol.18 No.3

Clutch engagement control is critical during launching process in a vehicle equipped with an automated manual transmission (AMT), which is a problem including muti-objective optimization and nonlinear control. In this paper, a optimal launching-intention-aware control strategy is proposed for clutch engagement. Firstly, a launching-intention-aware machine (LIAM) based on artificial neural network (ANN) is designed to identify the driver’s launching intentions. Then the optimal laws of clutch engagement for different launching conditions are obtained based on the dynamic programming (DP), which regard friction loss, vehicle shock, angular acceleration of engine and engine torque as the optimizing indexes. Next, a slidingmode controller (SMC) is designed for the clutch engagement. Finally, the performances of the optimal laws and the SMC are validated by the joint simulation of Simulink-AMESim, and the results show that the requirements of vehicle launching are met. The proposed clutch engagement control strategy would provide a better theoretical support for the practical-extended application of AMT.

The Committee on Pediatric Obesity of the Korean Society of Pediatric Gastroenterology, Hepatology and Nutrition newly developed the first Korean Guideline on the Diagnosis and Treatment of Obesity in Children and Adolescents to deliver an evidence-based systematic approach to childhood obesity in South Korea. The following areas were systematically reviewed, especially on the basis of all available references published in South Korea and worldwide, and new guidelines were established in each area with the strength of recommendations based on the levels of evidence: (1) definition and diagnosis of overweight and obesity in children and adolescents; (2) principles of treatment of pediatric obesity; (3) behavioral interventions for children and adolescents with obesity, including diet, exercise, lifestyle, and mental health; (4) pharmacotherapy; and (5) bariatric surgery.

Aims: Genome-wide association studies (GWAS) have identified several risk variants for prostate cancer (pCa) mainly in Europeans, which need to be further verified in other racial groups. We selected six previously identified variants as candidates and to define the association with PCa in Northern Han Chinese. Methods: 749 subjects from Beijing and Tianjin in Northern China were included. Six variants (rs10505474, rs7837328, rs4242384, rs7813, rs486907 and rs1058205) were genotyped by high resolution melting (HRM) assays. The individual and cumulative contribution for of the risk of PCa and clinical covariates were analyzed. Results: Among the six candidate variants, onlyrs10505474, and rs7837328, both locating at 8q24 region, were associated with PCa in our population.rs10505474 (A) was associated with PCa ($OR_{recessive}=1.56$, p=0.006); and rs7837328 (A) was associated with PCa ($OR_{dominant}=1.38$, p=0.042/$OR_{recessive}=1.99$, p=0.003). Moreover, we observed a cumulative effects between them ($p_{trend}=2.58{\times}10^{-5}$). The joint population attributable risk showed the two variants might account for 71.85% of PCa risk. In addition, we found the homozygotes of rs10505474 (A) and rs7837328 (A) were associated with PCa clinical covariants (age at onset, tumor stage, respectively) ($p_{age}=0.046$, $P_{tumorstage}=0.048$). Conclusion: rs10505474 (A) and rs7387328 (A) at 8q24 are associated with PCa and cumulatively confer risk, suggesting the two variations could determine susceptibility to PCa in the Northern Chinese Han population.
