A Study on an Independent Steering & Driving Control Algorithm for 6WS/6WD Vehicles

Joo-Young Choi,Dong-Hyung Kim,Chang-Jun Kim,Young-Ryul Kim,Sang-Ho Kim5,Chang-Soo Han 제어로봇시스템학회 2010 제어로봇시스템학회 국제학술대회 논문집 Vol.2010 No.10

Skid-steered vehicles are favored for military use in off-road operations because of their high maneuverability and mobility on extreme terrains and obstacles. There is a trend towards transforming steered tracked vehicles to skid-steered wheel vehicles for high speed at the expense of reduced mobility. Skid-steered vehicles turn by generating different longitudinal forces at the tires due to the application of different torques to the wheels on the opposite side of the vehicle. Conventional vehicles, however, cannot generate an opposite driving force at each side wheel. Using an independent steering and driving system, six-wheel vehicles can show better performance than conventional vehicles. Hybrid steering is a combination of skid steering in the load velocity and the steered wheel system at high speed. This steering enhances maneuverability under low speed and stability at high speed. This paper describes a 6WS/6WD vehicle for hybrid steering in three parts: the Vehicle Model, the Control Algorithm for Hybrid Steering, and a Simulation. First, the vehicle model is an application of the TruckSim software for 6WS and 6WD. Second, the hybrid steering control algorithm describes the optimum tire force distribution method for energy savings. The last is simulation and verification.

We should maintain firmly our stance in order to cope with any prejudice or any belief in terms of the process of dance socialization. At a time, in the field of sports sociology, it has majorly been projected in the sphere of learning of social science for a needed methodology for the subject sol- ution and not been established a characteristic knowledge and methodological sys- tem by accepting with almost non-criticism, therefore, the process of dance socialization should be emphasized on this, and making firmness a position of one of the part as a individual sphere of learning among the sports sociology, and then it, in its own way, should be needed to develops with deepest concerns to which we study a various variable factors with proper methodology on what shall we do a objective of study and of interesting relations on the process of dance socializtion of dancer together with a broaden understanding over the pre-existing sports sociology in order to build a creative and systematic knowledge system. The people who are living in mordern society can't overlook the society, there-fore we should enhance many things such as social nature, cooperation, esthetic sense, imaginative power and emotion by means of direct participation(a work of performance and a class) and indirect participation(viewing of artistic work, the affiliation of an aid association) which can be achieved through dance. It is very essential for goverment to devise and develop nationwide dancing program. When· it comes to our proposal for the future researcher, we should come up with well-planned research blueprint.

Objective: Occupational medicine specialists in the Busan, Ulsan and Kyung-Nam areas established an area-based occupational disease surveillance system and used this system to collected case information for the purpose of preventing occupational diseases Methods: l l hospital participated in this system. The authors selected five main diseases, which were hand-arm vibration syndrome (HAVS), work-related musculoskeletal disorder (WRMSD), occupational asthma, occupational skin disease and occupational and occupational lung cancer and established their case definitions. All cases were reported on the web, and real time analysis was conducted. Results: Between April 2001 and April 2003, 192 cases of HAVS, 118 cases of WRMSD, 33 cases of occupational asthma, 17 cases of occupational skin disease and 17 cases of occupational lung cancer (for a total of 377 cases of these five main diseases) were reported. most of the HAVS cases came from shipbuilding, and 172 of them (92.7%) were associated with grinding. Of the four main types of WRMSD, carpal tunnel syndrome (CTS) was the most prevalent with 46 cases and shipbuilding was also the main industry involved (83.9%). The ergonomic risk factors involved mainly associated with the hand. In 19 (57.6%) and 4 (12.1%) cases of occupational asthma, the agents involved. The causative agents of occupational lung cancer included Cr, welding fume, PAH, Ni, etc. 10(58.8%) of the cases were diagnosed as squamous cell carcinoma and 5(29.4%) as adenoma. Conclusion: This result showed that an area-based occupational disease surveillance system might provide an effective method of evaluating the prevalence of such diseases, however the Busan, Ulsan and Kyung-Nam provinces are too large to be treated as individual areas. Therefore, the authors suggest that each province should establish its own surveillance system.

A new silkworm variety 'Chilseongjam' was bred for special purpose as educational learning and festivals. Their breeding history and major characteristics are as follows. The Chilseongjam variety was selected and succeeded from the F1 of Galwon ${\times}$ C721 in 2009 autumn. They are showing 94% (spring & autumn) of high practical hatching ratio. The larval period of Chilseongjam (spring: 23 d, autumn: 24 d 3 h) was shorter than that of Daebakjam (spring: 24 d, autumn: 25 d 23 h). In the pupation percentage, Chilseongjam (spring: 96.6%, autumn: 86.1%) is similar to Daebakjam Daebakjam (spring: 96.3%) in spring, but autumn is lower than Daebakjam (autumn: 94.9%). Single cocoon weight (spring: 1.57 g, autumn: 1.29 g) and Cocoon yield (spring: 14.2 kg, autumn: 11.1 kg) were lower than those of Daebakjam (spring: 2.76 g, 25.4 kg, autumn: 2.19g, 20.2 kg), respectively. The new silkworm variety, Chilseongjam showed higher pupation rate than control variety. This variety can be used as a educational learning and festivals.

In insect defense system, antimicrobial peptides (AMPs) are one of important biological molecules to survive in a variety of environments. Insect can synthesize AMPs to protect against invading pathogens in humoral immune response. Taking more advantage of biological antimicrobial molecules, we report antibacterial activity of two cecropin type peptides, cecropin and moricin, isolated from the silkworm against four salmonella species. In this work, we purified antimicrobial candidate peptides (AMCP) from the extracts of immune challenged silkworm larval hemolymph by two-step chromatographic purification procedure, cation exchange and gel permeation chromatography. The molecular weights of purified peptides were estimated to be about 4 ~ 5 kDa by Tricin SDS-PAGE analysis, and identified as silkworm cecropin and moricin by NCBI BLAST homology search with their N-terminal amino acid sequences. As antibacterial activity assay, the purified peptides showed stronger antibacterial activity against Salmonella pathogens with an MIC value of $1{\sim}4{\mu}g/mL$. Therefore two cecropin type peptides purified from the silkworm will be valuable potential materials for development of new natural antibiotics.
