The purpose of this study was to investigate the effect of the multi-level marketing(MLM) on consumer by examing the degree of damage and the consumers's satisfaction with MLM as well as the overall realities of MLM including the degree of the recognition and the distribution route of the commodities. We analyzed 256 cases which had experienced with MLM among 430 questionnaires collected. The resulted are as follows. 1) Consumers showed a lack of knowledge about MLM regardless of experiencing it. And they were recognized positively with the quality and the availability of the commodities. Expendables such as kitchen utensils and cosmetics were the most favored articles. 2) Transactions with no written contract were the most frequent damage to the consumers, followed by no price-tag and the marketer's refusal of exchange or refund. 3) When we compared the degree of consumer's satisfaction with MLM to the ordinary distribution in terms of the price, quality of goods and the service offered, the consumers were satisfied with the quality of the commodities, though their whole impressin of MLM was not so much favorable.

This study was conducted to investigate the effect of microbial liquid manure(MLM) on the growth and yield characteristics of Altari radish (Raphanus sativus L.). MLM 1,000mg$.$L$^{-1}$ MLM 2,000mg$.$L$^{-1}$ and MLM 1,000mg L$^{-1}$ + microbial fermentation compost(MFC) 600kg/10a were treated. MLM was sprayed on leaves at 10, 20, and 40 days after planting. Leaf length and width of radish in all microbial fertilizer treatments were more vigorous than that of control significantly. Number of leaves was great in order of 1,000 mg$.$L$^{-1}$ MLM+600kg/10a MFC 〉2,000mg$.$L$^{-1}$ MLM〉1.000mg$.$L$^{-1}$ MLM. SPAD reading value was increased with treatments of 2,000mg$.$L$^{-1}$ MLM and 1,000mg$.$L$^{-1}$ MLM+600kg/10a MFC. Root length and weight of all the microbial fertilizer treatments tended to increase compared with control, and 1,000mg$.$L$^{-1}$ MLM+600kg/10a MFC treatment was the most effective.

A automatic flight control system(AFCS) of UAS needs to control its flight path along target path exactly as adjusts flight coefficient itself depending on static or dynamic changes of airplane's features such as type, size or weight. In this paper, we propose system which tunes control gain autonomously depending on change of airplane's feature in flight as adding MLM(Machine Learning Module) on AFCS. MLM is designed with Linear Regression algorithm and Reinforcement Learning and it includes EvM(Evaluation Module) which evaluates learned control gain from MLM and verified system. This system is tested on beaver FDC simulator and we present its analysed result.

Building the competitive advantage of Korean multi level marketing(MLM) companies is an important task when American multi-level marketing companies has successfully made inroads into Korean market. In this study, we search for the efficient marketing strategies for the MLM companies through a survey of distributors and consumers. The results indicate that the MLM companies must first deal with their image problem and improve their product quality and physical distribution system.

After 1990's, many multi-level marketing companies lave been introduced in Korea. These MLM companies operate their stores as same way as general retailing stores. The major characteristics of these MLM companys' store is that their main customers are distributors who sell the purchased merchandise to another customers. Many studies about merchandise display in general retailing stores were reported. But, there was less research about merchandise display in these special type stores such as MLM companys' stores. This paper investigates the effects of merchandise display on distributor's merchandise selection in channel flow of multi-level marketing company. For this purpose, we formulated four hypotheses about display variance in quantity, height, location, and related merchandise to analyze the effect of merchandise display methods in MLM companys' stores. The experiment had been proceeded in three stores in a MLM company for 6 weeks and the sales data were collected by POS. The methods to analyze the data were used ANOVA and T-test. Findings of this study are as follows; First, there was no effect to store sale by the interaction effect between merchandise display method and scale of store. Second, scale of store affected considerably the volume of sales of each store according to main effect analysis. Third, display variance in quantity, height, and location did not affect store sale. In the related merchandise display, however, sale in all store was increased. Fourth, in additional analysis considering merchandise display only, display variance in both height and location affected their sale in large scale store. Based on the above results, we may predict merchandise display can affect sale in MLM companys' store as well as general retailing stores. Therefore if MLM company has large scale store, it should consider merchandise display methods in its stores.

Although former scholarly studies mostly focus on exploring leadership effectiveness under the traditional hierarchical leader-subordinate relationship, the research of leadership performance for non-hierarchical organizational structures, particularly the mediating factors of higher-order goals, trust-in-leader, and self-efficacy have been ignored. This study, therefore, makes an attempt to ascertain the impacts of transformational leadership on the performance of subordinates through the mediating effects of higher-order goals, trust-in-leader, and self-efficacy and the differences of these effects in the context of multi-level marketing (MLM). Like the small-sample studies adopted by Barling, Weber, and Kelloway [1996], Barling, Slater, and Kelloway [2000] and Bass, Avolio, Jung, and Berson [2003], this study adopts a sample of 123 MLM distributors of an MLM company in Hong Kong, with a high response rate of 80.4%. The results indicate that the mediating effect of self-efficacy between transformational leadership and performance is significant under non-hierarchical organizational structures such as MLM in China.

데이터 증강기법은 추가적인 데이터 구축 혹은 수집 행위 없이 원본 데이터셋의 양과 다양성을 증가시키는 방법이다. 데이터 증강기법은 규칙 기반부터 모델 기반 방법으로 발전하였으며, 최근에는 Masked Language Modeling (MLM)을 응용한 모델 기반 데이터 증강 연구가 활발히 진행되고 있다. 그러나 기존의 MLM 기반 데이터 증강 방법은 임의 대체 방식을 사용하여 문장 내 의미 변화 가능성이 큰 주요 토큰을 고려하지 않았으며 증강에 따른 레이블 교정방법이 제시되지 않았다는 한계점이 존재한다. 이러한 문제를 완화하기 위하여, 본 논문은 레이블을 고려할 수 있는 Re-labeling module이 추가된 MLM 기반 한국어 데이터 증강 방법론을 제안한다. 제안하는 방법론을 KLUE-STS 및 KLUE-NLI 평가셋을 활용하여 검증한 결과, 기존 MLM 방법론 대비 약 89% 적은 데이터 양으로도 baseline 성능을 1.22% 향상시킬 수 있었다. 또한 Gate Function 적용 여부 실험으로 제안 방법 Re-labeling module의 구조적 타당성을 검증하였다.

Recently, studies using deep learning to analyze a large amount of text are being actively conducted. In particular, a pre-trained language model that applies the learning results of a large amount of text to the analysis of a specific domain text is attracting attention. Among various pre-trained language models, BERT(Bidirectional Encoder Representations from Transformers)-based model is the most widely used. Recently, research to improve the performance of analysis is being conducted through further pre-training using BERT's MLM(Masked Language Model). However, the traditional MLM has difficulties in clearly understands the meaning of sentences containing new words such as newly coined words. Therefore, in this study, we newly propose NTM(Newly coined words Target Masking), which performs masking only on new words. As a result of analyzing about 700,000 movie reviews of portal 'N' by applying the proposed methodology, it was confirmed that the proposed NTM showed superior performance in terms of accuracy of sensitivity analysis compared to the existing random masking.

GUI program for analyzing directional spectrum waves is introduced in this paper Basically, MLM (Maximum Likelihood Method) was used for this program which was additionally consisted of performing spectral and time domain analysis for two dimensional irregular waves. Moreover, the directionality of directional spectrum waves generated by single summation and double summation method was investigated based on MLM. The directionality from each summation method has good agreement compared with that of target wave spreading function in the case of single wide directional spectrum waves. In addition to this, the resolution of directionality in double summation method was investigated as introducing coherence function between each wave component
