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.

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.

정동원 ( Dong Won Jeong ),한종호 ( Jong Ho Han ) 한국물류학회 2012 물류학회지 Vol.22 No.2

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%.

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.

We usually say that there are two cornerstones in science. One of the cornerstones is reproducibility and the other is predictability. Reproducibility and predictability ate expressions that causal relations (or Cause - effect relations) exist in nature. The symmetry principle is derived directly from the causal relation (or the equivalence principle). Symmetry and entropy are related to each other. From the symmetry evoluation principle it follows immediately that evoluation with increasing degree of symmetry implies irreversibility, or time-reversal asymmetry, of the laws of evoluation The role of time in the description of the physical universe by two points of view - one aiming at its elemination and the other based on the brief that is fundamental and irreducible. We discuss the physices of time corresponding to reversible phenomena (with time symmetry) and irreversible process (with broken time symmetry) as described by entropy. The entropy, amount of disorder of the system, plays the key role to make the transformation from equilibrium to nonequilibrium. We have reviewed the physics text books of high school and found that there is no attempt to explain the relation between entropy and disorder. Here we suggest that it is desirable to give high school students a physical sense for the relation between entropy and the direction of evoluation of nature.

Direct Black 38, a kind of benzidine-based azo dye, is widely used as a dye for fabric, leather, cotton, cellulosic material, paper, wool, silk, and so on. Benzidine-based azo dyes are proven as a mutagen and linked to bladder cancer. In 1978, National Institute for Occupational safety and Health recommended that three widely used benzidine-based dyes(Direct Black 38, Direct Blue 6, and Direct Brown 95) should be treated as carcinogens. In this experiment, metabolism of the benzidine-based dye, Direct Black 38 was examined by using an isolated liver perfusion system. To measure the metbolites of Direct Black 38, 8.0μM, 30.5μM and 63,3μM of Direct Black 38 was added into the recirculating perfusate of the isolated perfused rat liver. Samples were collected at 0, 10, 20, 30, 60, 90, 120 minute. They were treated with sep-pak and methanol, and the metabolites were detected and quantified with high performance liquid chromatography(HPLC). Residual non-reactive dye in the perfusate and liver was reduced to benezidine and then analyzed by HPLC. Detected metabolites of Direct Black 38 were benzidine, N-acetybenzidine, and N,N'-diacetylbenzidine. The average concentration of benzidine was 0.1μM and this concentration was maintained throughout the experimental period. The average concentration of Nacetylbenzidine was 0.22μM and took the same pattern of benzidine. When 30.5μM of Direct Black 38 was added to the perfusate, only N,N'-diacetylbenzidine increased slightly with time. From the above results we suggest that only small amount of Dirst Black 38 might be metabolized to benzidine regardless of the s, amount of the Direct Black 38. There are some possible explanations. The liver was damaged during the perparation. And the function of the perfused liver decreased rapidly because adsorbing of dye. The benzidine, acetybezidine and diacetylbenzidine metabolized to other metabolites were not detected in this experiment.

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).

This study was carried out in order to estimate the domestic sewage quantities-qualities from combined sewer in Iksan and Hameol. To investigate the domestic sewage quantities-qualities from combined sewer, sample were collected 2 times during this study period at ten points. Flow rate analysis demonstrates a major morning and evening peak between 08:00∼10:00 and 19:00∼22:00, respectively. The concentrations of BOD were in the range of 23∼340㎎/ℓ and 28∼318㎎/ℓ, respectively. The highest concentrations of BOD occurred in the point 1. The concentrations of suspended solids were in the range of 18∼330㎎/ℓ and 13∼85㎎/ℓ, respectively. The pollution loading runoff after a rainy season decreased compared to that made before the rainy season. Comparisions with data for second survey show lower than first survey, from domestic sources, of many dilute water often regarded as having a mainly groundwater origin.

Marathon 競技의 Lap-time 調節에 關한 硏究

元鐘世 건국대학교 1979 學術誌 Vol.23 No.2

As the activities of all sports are geared toward dignified, and gentlemanly victory, marathon race is a sport which requires record establishment on a lonely and long time running in a long distance race. Korean marathon race in the past maintained the record which relied upon the non-scientific method of training and innate physical strength from 1927 to 1965 without lap-time. After 1966, lap-time which will charge the restoration of Korean marathon was to be introduced. The lap-time which is now being used have applied the method of dividing by eight. Five thousand meter lap-time has some strong point, but the variation of time will be expected by the weather condition, height of the course, and a sense of superiority or inferiority of the player. This study was to stress 10,000 meter lap-time in order to strengthen the system of 5,000 kilometer lap-time. Player himself will introduce the average record to marathon race by the record of 10,000 meter on the basis of three times a day so as to control the lap-time freely in case of race. It is necessary to practice a lot in controlling the lap-time by the player unrestrictedly himself and there is no particular method except the practice to feel the sensitivity of speed. It is also necessary for the player to face the contest, rank, record, strateg yof the game, but the most important thing is to distribute the effective lap-time. Lastly, so as to distrubute the effective method of lap-time, it is expected to introduce the method of 10,000 meter lap-time in the improvement of Korean marathon race without a moment's delay.

Saemankeum Construction Plan, constructing a 33km tide embankment, is a project that builds 28,300ha land and 11,800ha artificial lake. Since there is a high potential that eutrophication could appear at Saemankeum Lake, its construction has attracted a lot of attentions from academic circles as well as the government. Thus, this study is to estimate the primary productivity in Saemankeum area. To investigate the primary productivity, sample were collected 7 times from May to November in 1998 at seven points. The results were as follows ; The concentrations of Chlorophyll-a in this study area were in the range of 5.3∼46.2㎎/㎥. Mean primary productivity in Saemankeum area was estimated to be 161.6∼990.2㎎C/㎡/d which is wuite similar value to the recent results from the Korea. The highest production rate was found at October in 1998. Therefore, trophic level of the study area was ranged as mesotrophic level by Linkens' Method.
