A Study on the Feasibility of Win-Win Growth in Wholesale Market

Jong-Moon WON 한국유통과학회 2020 The Journal of Industrial Distribution & Business( Vol.11 No.4

Purpose: At a time when the distribution industry is dominated by capital and technology, win-win growth among businesses groups (BGs) in wholesale market is becoming a social issue. Therefore, through analysis of market growth, market concentration (MC) and market power (MP), we want to identify the structure of the wholesale market and the competitiveness of the BGs in terms of market share (MS), sales-profit ratio (SPR), and labor productivity (LP) to explore the possibility of win-win growth. Market situation: Wholesale and Retail sales ratio (W/S) continues to increase, which also means inefficiency in distribution channels or opportunities in wholesale markets. Wholesale sales have grown 8.3 percent annually over the past 15 years, while the number of companies and workers has declined since 2017, which is why some restructuring is believed to begin in the wholesale industry. In terms of MC and MP, the growth potential of SBG can be found in FCB, ARM, FBT and CME BTs. Methodology and data: Through ANOVA and Regression Analysis, the 2015 Economic Census Data of KOSTAT was analyzed. Results: The results of ANOVA show that statistically significant SBG has a larger MS than LBG. The SPR was not different among BGs. LP is higher for LBG than for other BGs. Regression results show that the employment weight (EW) and the company size (SC) have positive effects on the MS, but the company weight (CW) and employment size (SE) have negative effects. In the case of SPR, the CW is positive and the EW is negative. In addition, LP appears to be more positive as SC in the BGs is larger. Conclusions: Although there is sufficient potential for SBG in the wholesale market, there is a problem that needs to increase LP. Therefore, the SBG needs to restructure in terms of number of companies and SC to improve the efficiency of employment. In terms of MC and MP, the SBG looks for possibilities in FCB, ARM, FBT and CME BTs. In addition, SBG that seeks higher returns with human services rather than simple sales is found to be competitive in the HHG, MES and CME BTs.

This paper presents the kinematic correction method for wheeled-mobile robots with 2 d.o.f. and a design of the velocity trajectory for wheeled-mobile robots'line-travelling. We derive the relative wheel-weight and the absolute wheel-weight to correct the radius of both wheels. And we use the curvature angle to correct displacement of wheel base. We show that wheeled-mobile robots can't move along a straight-line perfectly and the velocity trajectory must have the chage of velocity at least one. To prove efficiency of the method in this paper, we experiment on the wheeled-mobile robots with 2 d.o.f. and discuss the results.

본 논문은 2 자유도 구륜 이동로보트의 기구학 모델과 기준모델 적응제어기 설계를 다루었다. 구륜 속도와 본체 속도를 계산하기 위하여 정기구학(forward kinematics)과 역기구학(inverse kinematics)를 유도하였으며, 제어변수의 수와 제어입력의 수가 동일하게 되도록 제어변수를 극좌표로 변환하였다. 구륜 이동로보트의 경로추적을 위한 제어기를 제안하였으며, 제어기 매개변수는 기준모델 적응제어(reference-model adaptive control, MRAC)에 기초한 적응법칙(adaptation law)에 의해 매 단계마다 갱신된다. 설계된 적응제어기를 분석하고, 제어 시스템의 안정성과 수렴성을 증명한다. 제어시스템의 유효성을 입증하기위해 모의실험을 수행하고, 그 결과를 제시한다. This paper presents the kinematic model and the design of a model-reference adaptive controller for wheeled-mobile robots(WMRs) with 2 d.0.f. We derive the forward kinematics and the inverse kinematics to calculate the wheel-velocity and body-velocity. The controlled variables are represented in the polar coordinate so that the number of the controlled variable can be reduced to the same number as the control input. A controller is proposed for path tracking, and then controller parameters are modified by adaptation law based on reference-model adaptive control(MRAC) each step. The adaptive controller is analyzed, and its stability and convergence are proved. Simulation is conducted to prove efficiency of the control system and the results are showed.

Gastritis cystica profunda (GCP) is a disease characterized by hyperplastic and significant extension of cystic dilatation of the gastric mucous glands, which results in a cystic lesion in gastric submucosa. It often occurs on the part of gastroenterostomy, but can be found in the stomach without any previous surgery. GCP has variable gross finding including solitary polyps, diffuse ones, submucosal tumors, and rare giant gastric mucosal fold. It is difficult to tell GCP from a cancerous lesion by gross finding that the disease demands a necessary tissue biopsy, though GCP is commonly showed as a benign in the progress. We report a case of GCP in polypoid types diagnosed by endoscopic polypectomy.

Computerization of clinical microbiology, including parasitology and stool examination, using two microcomputers (LC475. Macintosh), resulted in more efficient specimen handling, frequent reporting and reduction of workload by avoiding repeated clerical work. And it will serve as a useful tool to improve quality control and to control hospital infection. We experienced some important, practical things about file structure, procedure and input-layouts for clinical microbiology, which will be needed to construct laboratory information system (LIS).

Object : This study was performed to increase the sensitivity and specificity for screening the examinee of second hearing test. Methods : Study subjects were 219 workers who exposed more than average 80dB. They were taken the hearing test two times, before noose exposure and at 1 hour to 4 hours after worksite noise exposure. To investigate the ambient noise workers who were taken the hearing test in the test room which ambient noise was less than 45dB were classified Group I and the others were classified Group II . To calculate the sensitivity and specificity we made it gold standard whether worker had noise induced hearing loss. Results : Difference of hearing loss between before and after noise exposure for left and right ear was 11.4 dB and 11.7 dB respectively at 500 Hz, 8.7 dB and 9.6 dB at 1,000 Hz, 6.3 dB and 6.9 dB at 2,000 Hz and 6.9 dB and 7.4 dB at 4,000 Hz In Group I. That for left ear and right ear was 5.8 dB and 4.9 dB at 500 Hz respectively, 5.4 dB and 6.4 dB at 1,000 Hz, 6.3 dB and 5.3 dB at 2,000 Hz, and 5.5 dB and 5.8 dB at 4,000 Hz in Group II. The sensitivity was 100 in both Groups and the specificity was increased to 58.3 and 71.8 in Group I and Group II respectively until 10 dB was deducted from hearing level at 1,000 Hz and 4,000 Hz. Conclusion : When the screening hearing test was performed at worksite, we might deduct 10 dB from measured hearing level to increase the specificity without reduction of sensitivity.

This paper presents the kinematic correction method for wheeled-mobile robots with 2 d.o.f. and a design of the velocity trajectory for wheeled-mobile wheel-weight to correct the radios of both wheels. And we use the curvature angle to correct displacement of wheel base. We show that wheeled-mobile robots can't move along the straight-line perfectly and prove that it is attributed to the acceleration constraint of motor controllers and the velocity trajectory have to get a change of velocity in order that wheeled-mobile robots may converge to the straight line. And we experiment on the wheeled-mobile robots with 2 d.o.f. and discuss results.

21세기 동북아 물류거점화 전략방안

원종문 동서대학교부설연구소 1997 연구소 논문집 Vol.2 No.-

우리나라는 21세기 대외 경쟁력을 강화하기 위하여 물류선진화라는 필연적인 목표를 달성하여야 한다. 물류의 최적화, 연게화 그리고 공동화를 통한 물류산업의 선진화는 경쟁력제고에 있어서 제조업체의 기술개발보다 더욱 중요한 요인이 될 수 있고 또한 Logistics에서 Holistic logistics로의 전환 즉 최적화에서 연계화로의 전환의 필요성을 인식하는 것은 물류선진화를 출발점이 될 수 있다. 상대적으로 낙후한 물류산업, 비용절감의 마지막 보루인 물류비 절감의 문제, 유통산업의 지각 변동에 따른 물류산업의 역할 증대, 다품종ㆍ소량시대에 적합한 물류전문업체의 필요성, 세계화를 통한 무역량과 물동량의 증가는 물류산업의 비중을 더욱 확대해 가고 있고, 그리고 동북아 물류 HUB로서 동아시아의 중심국가의 역할을 추구하고자 하는 정부의 노력은 더욱 물류선진화의 필요성을 증대시키고 있다. 그러므로 물류선진화를 위하여 현재 우리나라가 당면하고 있는 물류산업의 실태와 문제점을 분석하여 보고 문제점 해결을 위한 정부의 노력들이 더욱 효과를 발휘하기 위해서 각종 물류관련 정책들과 사업게획들이 유기적인 연계를 가지고 추진되어야 하며, 계속적인 검토와 조정 또한 필요하다. 현재 동남아 물류중심국가인 싱가폴과 유럽의 물류거점 국가인 네덜란드를 연구하는 것이 우리에게 물류정책의 방향설정과 사업계획을 수립하는데 도움이 될것이며, 21세기 물류선진국가로 도약하기 위한 우리 나라는 국가적 투자 및 규제완화 정책뿐만 아니라 해외기업 유치와 물류 HUB로서의 역할을 효율적으로 수행하기 위한 민간기업차원의 국제경영전략도 필요하다.
