Ginseng in Korea has not only the big production value but also till a good reputation from overseas in the name of 'Korea Ginseng'. Having spread rapidly nationwide from 2000 year, its production keeps on increasing but its consumption becomes lazy and its price is also falling down because of comsumer's concern about mainly overusing pesticide for ginseng. In order to cope with this problem, the government introduced the GAP certification system to ginseng in 2006 to reflect consumer's needs for food safety. This system will be a good opportunity to promote ginseng consumption dramatically. In this aspect it is very important to know how well this system is established and how ginseng farmers build marketing strategies to draw new wind in the market. This study was carried out to look over the GAP certified ginseng system and show its marketing strategies using 4P's(product, place, promotion and price). The main results are as follows. GAP ginseng system currently has some weaknesses such as lack of systematic certification management and after-service, nonrealistic certification fee and poor linkage from production to consumption. In the marketing mix strategies, product strategy suggests that the most desirable appearance be transplanted ginseng filled with branch roots and 4 to 5 year-ginseng, and it is necessary to choose multi-brand strategy divided for present into for self-sufficiency and family brand strategy by use if its brand enlarges to processed products in the future. In the place strategy, 3 stages like 'producer group' - 'GAP certified facility' - 'sales shop' are based as the physical marketing channel according to traceability, and connected with giant retail market and environment friendly stand, and if its sales volume enlarges, it should be considered the GAP ginseng specialized marketplace which is a type of chain store. In the promotion strategy, the promotion of government level is necessary at first and producer alliances require the promotion targeting at the group of women under 40 with differentiation from price, quality, and safety. In the price strategy, the early stage-high price strategy which sets 20~25% higher for self-sufficiency and 30~35% for present is desirable.

Competitive bidding in construction is concerned with contractors making strategic decisions in respect of determination of bid price if contractors opt to bid. This study presents a strategy model for deciding optimum tender price with reflecting appropriate profit in competitive bidding using Bayesian regression analysis (BRA). The purpose of the developed model is to help contractors to secure suitable profitability by predicting the actual profit based on key variables. They may affect construction cost at bidding phase, ultimately which help contractors to secure high quality output. The model was tested empirically by application to a bidding dataset collected from a large South Korea contractor. BRA allows contractors to estimate more accurate actual profit by reflecting not only objective information but also subjective experiences and judgments. Consequently, the model can contribute to improvement of decision-making process for setting an optimum tender price.

The purpose of this study is to analyze consumption of homemade organically processed food (HOPF), and to derive directions for consumption promotion of HOPF. A survey was conducted for quantitative analysis regarding consumption. This study used an Ordinal Logistic Regression Model to derive more significant results in analyzing factors of consumption. The findings was that younger consumers with high income are more likely to purchase HOPF. And those consumers with high price and quality contentment are more likely to purchase HOPF. And contentment with certification institutions and improvement of health have a significant positive relationship with consumption. Consumers were found to pay 51 percent more for HOPF than for non-HOPF products. This level show that the current level of price premium for HOPF is 51 percent higher than their desired level. In order to reduce the price premium for HOPF, effective policy programs should be developed. A targeted market strategy to sell HOPF to younger consumers with high income is needed to boost consumption. A strict certification management system should be established to enhance consumer reliability in HOPF.

In a duopoly situation, one firm can gain competitive advantage by attracting the price-sensitive customers from its competitor leading to higher profits through higher sale revenue for the competing company. A simulation study in which there are two electric car manufacturers with agent based modelling was conducted in order to verify this contention. The first step consisted of defining the baseline. Simulations of 1000 times and agent-based modelling were conducted with the assumption that company 1 reduced its price to the maximum of 20% thereby contributing to the switch-over of a maximum of 40% of the price sensitive customers of company 2. The results of 1000 simulations and agent-based modelling highlighted that price reduction by company 1 resulted in a significant increase in the number of customers, presumably due to switch-over from company 2 and there was a corresponding increase in revenues from both of the sales avenues. Thus, Company 1 achieved competitive advantage by marketing its cars to the customers of Company 2 using price reduction strategy to attract them. This study has ramifications for companies that aim to sway the price sensitive customers from a competitor.

The paper analyzed on the level of consumer member's awareness to green marketing strategies (4P's; product, price, place and promotion strategies) of Hansalim specialty shops for environmentally friendly agri-products. For the study, Hansalim-Cheonanasan members had been surveyed. Consumers purchase environmentally friendly agri-products because quality and freshness of those is good. The difference in amount of the average monthly purchase between loyal customers and disloyal customers is about 130,000 won. And customer's awareness is that the first is promotion strategy, the second product strategy, the third place strategy, the last price strategy. The average monthly purchase is related with product strategy in correlations between the 4P's each other. If Hansalim maintains a product strategy, promotes extensively and keeps their product standard, more consumers will purchase Hansalim products because the most important one of effect of green marketing strategies on consumer behavior is products. Hansalim needs to go into action to increase recognition. Some of consumers have misconcepts or don't know about the 4P's well. If Hansalim promotes positively considering interrelationship about 4P's strategies or other strategies, the consumers awareness will be changed more effectively. This study shows that balanced 4P's is better than only one superior strategy because of the correlation amomg green marketing strategies.

We proposed a neural network based “left shoulder”detector. The auto-associative neural network was trained with the “left shoulder”patterns obtained from the Korea Composite Stock Price Index, and then tested out-of-sample with a reasonably good result. A hypothetical investment strategy based on the detector achieved a return of 132% in comparison with 39% return from a buy and hold strategy

암호화폐시장이 지속해서 성장함에 따라 하나의 새로운 금융시장으로 발전하였다. 이러한 암호화폐시장에 관한 투자전략 연구의 필요성 또한 대두되고 있다. 본 연구에서는 단기매매전략과 딥러닝을 결합한 암호화폐 투자 방법론에 대해 실증분석을 진행하였다. 투자 대상의 암호화폐를 이더리움으로 설정하고, 과거 데이터를 기반으로 최적의 파라미터를 찾아 이를 활용하여 실험 모델의 투자 성과를 분석하였다. 실험 모델은 변동성돌파전략, LSTM(Long Short Term Memory)모델, 이동평균 교차 전략, 그리고 단일 모델들을 결합한 결합 모델이다. 변동성돌파전략은 일 단위로 변동성이 크게 상승할 때 매수하고 당일 종가에 매도하는 단기매매전략이며, LSTM모델은 시계열 데이터에 적합한 딥러닝 모델인 LSTM을 활용하여 얻은 예측 종가를 이용한 매매방법이다. 이동평균 교차 전략은 단기 이동평균선이 교차할 때 매매를 결정하는 방법이다. 결합 모델은 변동성돌파전략의 매수 조건과 변동성돌파전략의 목표 매수가보다 LSTM의 예측 종가가 큰 경우 매수하는 조건이 동시에 만족하면 매수하는 규칙이다. 결합 모델은 변동성돌파전략과 LSTM모델의 파생 변수를 활용해 매수 조건에 AND와 OR를 사용하여 만든 매매 규칙이다. 실험 결과, 단일 모델보다 결합 모델에서 투자 성과가 우수함을 확인하였다. 특히, 데일리 트레이딩과 매수 후 보유의 누적수익률은 -50%이하인 것에 비해 결합 모델은 +11.35%의 높은 누적수익률을 달성하여 하락이 지속되던 투자 기간에도 기술적으로 방어하며 수익을 낼 수 있음을 확인하였다. 본 연구는 기존의 딥러닝기반 암호화폐 가격 예측에서 나아가 변동성이 큰 암호화폐시장에서 딥러닝과 단기매매전략을 결합하여 투자 성과를 개선하였다는 점에서 학술적 의의가 있으며, 실제 투자 시 적용 가능성을 보여주었다는 점에서 실무적 의의가 있다.
