        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 servic

        물류산업은 경제 발전에 중요한 역할을 담당하며, 산업경쟁력과 국가경쟁력을 결정하는 중요한 요소로 작용하고 있다. 본 논문에서는 산업연관분석을 이용하여 물류산업의 국민경제적 파급효과를 분석하고자 한다. 먼저 수요유도형 모형을 이용하여 물류산업의 타 산업 생산유발효과, 부가가치 유발효과, 취업유발효과를 살펴본다. 다음으로 상대적으로 복잡성 때문에 잘 사용되지 않았던 공급유도형 모형 및 레온티에프 가격모형을 적용하여 물류산업의 공급지장효과 및 물가파급 효과를 살펴본다. 이러한 분석은 모두 물류산업을 내생부문이 아닌 외생부문으로 다룸으로써 물류산업을 중심으로 이루어지게 된다. 주요 분석결과를 요약하면 다음과 같다. 물류산업의 1원 생산은 타 산업의 생산을 0.5104원만큼 유발하며, 타산업의 부가가가치를 0.1722원만큼 유발한다. 또한 물류산업의 10억원 생산은 타산업에서 2.2554명의 취업을 유발한다. 한편 물류산업에서 1원의 공급이 이루어지지 못할 때, 타 산업에서는 0.9387원의 생산차질이 발생하여 공급지장효과가 제법 큰 편이다. 마지막으로 물류산업의 가격이 10& 상승했을 때, 국민경제 전체적으로 미치는 물가파급효과는 0.0276%로 분석되었다. The logistics industry in Korea plays a major role in the national economy development and to make decision nation and industrial competitiveness, This study attempts to examine the economic impacts of the logistics industry using an inter-industry analysis, Specially, the study investigates production-inducting effect, value added inducing effect, and employment-inducing effect of the logistics industry based on demand-driven model. Moreover, the study deals with supply shortage effect and sectoral price effect by using supply-driven model and leontief price model, respectively, which have been rarely used because of their complications involved in computaiton. These analyses pay particular and close attention to the distribution industry by taking it as exogenous rather than endogenous. Some interesting findings emerge from the study. First, the production of 1.0 won in the logistics industry induces the production of 0.5104 won and the value-added of 0.1722 won in other industries. Second, the production of 1.0 billion won in the logistics industry causes the employment of 2.554 persons in other industries. Third, the supply shortage of 1.0 won in the logistics industry disables other industries to produce 0.9387 won. Finally, an increase of 10% in price level of the logistics industry raises the overall price level by 0.0276%.

        데이터 마이닝을 활용한 한국 프로야구 구단의 승패예측과 승률 향상을 위한 전략 도출 연구

        김원종 ( Kim Won-jong ),최연식 ( Choi Yeon-sik ),유동희 ( Yoo Dong-hee ) 한국스포츠산업경영학회 2018 한국스포츠산업경영학회지 Vol.23 No.3

        본 연구에서는 데이터 마이닝 기법을 활용하여 한국 프로야구의 승패예측모형을 구축하는 실험을 진행하였다. 이를 위해, 2017년에 실시된 한국 프로야구 10개 구단의 전체 경기 중 무승부 경기를 제외한 1,418경기에 대한 자료를 사용하였다. 승패예측모형에는 의사결정나무, 베이즈넷, 인공신경망 알고리즘과 앙상블 기법인 배깅과 부스팅이 사용되었으며, 그 결과 배깅 기법에 인공신경망을 적용한 예측모형에서 가장 높은 예측률인 85.18%를 기록하였다. 다음으로 의사결정나무 기반 예측모형을 활용하여 한국 프로야구 전체 구단에 관한 8개의 승패규칙을 도출하였다. 여기에서 승패규칙은 승패예측에 영향을 미치는 주요 요인들인 팀출루율, 팀타율, 피안타, 안타, 타석, 타수로 표현되며, 도출된 규칙을 바탕으로 구단의 승률 향상에 도움을 주는 전략을 제안하였다. 또한 플레이오프 진출 구단과 미진출 구단에 관한 승리규칙을 각각 4개씩 도출하였고 이를 바탕으로 두 집단에 맞춤화된 승률 향상 전략을 제시하였으며, 실제 구단에서 선수를 영입한 방향과의 비교를 통해 제시된 전략의 활용 가능성을 확인하였다. This study conducted an experiment to develop win-loss prediction models for the Korean professional baseball league using data mining techniques. To this end, we used data on 1,418 games from all games played by the ten Korean professional baseball teams in 2017, except draw games. We developed win-loss prediction models using not only a decision tree, Bayse net, and artificial neural network algorithms, but also ensemble methods, such as bagging and boosting. As a result, first, we found that the artificial neural network-based prediction model using the bagging method reported the best accuracy (85.18%). Second, we derived eight win-loss rules for entire teams from the decision tree-based prediction model. These rules consist of six influential factors: team on base average, team batting average, hit by opponent, hit, plate appearances, and at bat. Using the derived rules, we proposed helpful strategies for improving the winning rate. Third, we derived four winning rules for both playoff teams and non-playoff teams; using the rules we proposed customized strategies for improving the winning rate of the two different groups. Finally, we confirmed the feasibility of the proposed strategies by comparing non-playoff teams’ actual player recruitment strategies.

        김순열 ( Soon Yeol Kim ),윤종원 ( Jong Won Yoon ) 동국대학교 한의학연구소 1996 東國韓醫學硏究所論文集 Vol.5 No.-

        The purpose of this study was to generalize the conception of chronic pelvic pain(CPP)through the literature of oriental medicine and occidental medicine. The results are obtained as follows. First, chronic pelvic pain(pain of more than 6 months' duration) may include pain of gynecologic, gastroenterologic, urologic neurologic, and musculoskejetal origin. In this study, the etiologic of chronic pelvic pain may remain obscure and the relationship between certain types of pathologic, such as endometriosis or adhesions, and the pain response may be inconsistent and often inexplicable. Second, the causes of CPP through the literature of oriental medicine were reviewed as pains due to a wind-pathogen, a cold, disorder of Qi, disorder of blood stasis, a improper diet, disorder of fluid, and deficiency type etc... And the charateristic pains were concerned with a aching pain, a heavy pain, a distending pain, a pain due to mass in the abdoman, a pain likes pulling etc... The degree an4 classification of charateristic pains in current of time were dependent on subjective factors. Third, in oriental medicine, it wasn`t to be suggested concretely recognition of etiological factor in pain, But they recognised that facters were influenced by pain. For example, diretic peripheral demages were concerned with a blood stasis, a phlegm, a damp phlegm, heart, and the pains that were occurrenced by sevn emotions were concerned with a stagnancy of Qi or a stagnancy of liver-Qi.

        Occurrence of three troublesome lepidopterous pests, Ostrinia furnacalis, Helicoverpa armigera and Pseudaletia separata in corn cultivation of the reclaimed land were recorded using sex pheromone traps from 2012 to 2014. In case of O. furnacalis adult, two generations were observed in a year and its occurrence pattern was very regular. The 1st generation showed the highest occurrence in late May-early June and the 2nd generation was in late July-early August. On the other hand, H. armigera occurred at least three times a year but its occurrence was somewhat irregular. H. armigera adult showed the highest occurrence in mid May, late June, early August, respectively in 2012 but their occurrence patterns of the 2nd and 3rd generations were varied in 2013 and 2014. In case of P. separata, a few number of adult were captured during the survey period, indicating few number of P. separata migrated from China. Based on the control effect of O. furnacalis by Etofenprox and Carbofuranin 2012, June 26 treatment showed the highest control rate with 96.8% for Etofenprox, 85.8% for Carbofuran, respectively. Late treatment at June 19 and June 26 significantly decreased the control rate of O. furnacalis and June 26 treatment showed the lowest control rate of 1.9% for Etofenprox. 18.1% for Carbofuran, respectively.

        본 연구에서는 강원도 원주시와 횡성군애에 식재 활용 되고 있는 조경 식물의 이용 상황을 조사 분석하여 현재 어떠한 식물이 어떻게 이용되고 있는가를 파악함으로서 그 이용방법에 대한 개선 방안을 모색하고 아울러 원주시와 횡성군의 아름다운 경관 형성을 위한 관리 방법 등을 제시하였다. This study was executed to find out how to improve the planting and use of landscaping plants in Weonju and Hoengseong. 1. The number of street trees were 22.068 and the species number were 10 species in Weonju in 2004. The major species of street trees were Ginkgo biloba(58%), Prunus sargentii(15%), Zelkova serrata(9%), Prunus armeniaca var, ansu(8%), and Acer palmatum(6%). The ratio of native species versus exotic were 50:50. In Hoengseong, the number of street trees was 13,500 and the specise number were 15 species. The major species of street trees were Prunus sargentii(42%), Ginkgo biloba(23%), Acer triflorum(12%) Prunus armeniaca var, ansu(6%), and Prunus mume(4%). The ratio of native species versus exotic were 67:33. The species of which planting frequency within two areas was very high were Ginkgo biloba and Prunus sargentii. 2. It is necessary to select tree species suitable for the characteristics of the locality and to raise distinctive street trees that contribute to the tourist industry. For the purpose, the appropriate street trees in two areas are Cornus controversa, Quercus aliena, Zelkova serrata. Prunus padus, Sorbus alnifolia, Sorbus comixta, Albizzia julibrissin, Acer triflorum. Styrax japonica, Chionanthus retususm Celtis sinensism, Prunus yedoensis, Malus sieboldii, Crataegus Pinnatifida, Prunus armeniaca var. ansu and Pyrus pyrifolia etc.. 3. Appropriate pruning adds to the aesthetic and prolongs the useful life, it also requires less managing of insects and diseases to maintain good healthy of street tees. Street trees were not properly pruned due to electric lines and shortage of pruning information. The pruning was controlled by Korea Electric Power Co, which has no pruning information. Pruning must be maintained by a professional landscape company to maintain good shape such as with Bonsai. The shrubs planting zone between street trees and other trees, and preservation plates were established for healthy of street trees. They have to be repaired and maintained well to keep better environmental conditions. The proper fertilization, the control of pests and diseases, the installation of drainpipe and the use of soil brought from another place were needed to improve the planting, use and maintenance of landscape plants. 4. The species number of school trees and flowers of 102 schools in Weonju and Hoengseong were 17species, 16species respectively. The major species of school trees in Weonju were Juniperus chinensis(24%), Ginkgo biloba(17%), Pinus densiflora(14%), Zelkova serrata(14%), and Pinus koraiensis(9&), and those of school trees in Hoengseong were Pinus koraiensis(44%), Abies holophylla(25%), Juniperus chinensis(8%), and Ginkgo binloba(8%).
