This study analyzed the effect of the farm's sense of community on participation satisfaction by participating in the contract cultivation of onions. To this end, we investigated the participation satisfaction with the sense of community's emotional connection, fulfillment of need, membership, and influence. According to the analysis of the sense of community of onion farmers, the definition of need, membership, and influenced participation satisfaction and were statistically significant. It was also shown to affect sense of community in the order of membership, Influence, fulfillment of need, and emotional connection. Therefore, it is necessary to form a continuous relationship with the leader and Nonghyup, to lead to improved farm income, induce pride as a member of participating farmers, and form a positive perception among onion farmers.

Nearby young moving groups (NYMGs hereafter) are gravitationally unbound loose young stellar associations located within 100 pc of the Sun. Since NYMGs are crucial laboratories for studying low-mass stars and planets, intensive searches for NYMG members have been performed. For identification of NYMG members, various strategies and methods have been applied. As a result, the reliability of the members in terms of membership is not uniform, which means that a careful membership re-assessment is required. In this study, I developed a NYMG membership probability calculation tool based on Bayesian inference (Bayesian Assessment of Moving Groups: BAMG). For the development of the BAMG tool, I constructed ellipsoidal models for nine NYMGs via iterative and self-consistent processes. Using BAMG, memberships of claimed members in the literature (N~2000) were evaluated, and 35 per cent of members were confirmed as bona fide members of NYMGs. Based on the deficiency of low-mass members appeared in mass function using these bona fide members, low mass members from Gaia DR2 are identified. About 2000 new M dwarf and brown dwarf candidate members were identified. Memberships of ~70 members with RV from Gaia were confirmed, and the additional ~20 members were confirmed via spectroscopic observation. Not relying on previous knowledge about the existence of nine NYMGs, unsupervised machine learning analyses were applied to NYMG members. K-means and Agglomerative Clustering algorithms result in similar trends of grouping. As a result, six previously known groups (TWA, beta-Pic, Carina, Argus, AB Doradus, and Volans-Carina) were rediscovered. Three the other known groups are recognized as well; however, they are combined into two new separate groups (ThOr+Columba and TucHor+Columba).

In this paper, we investigate visual and quantitative analysis of different tastes in the liquids using multi-array chemical sensor (MACS) based on the ion-selective electrodes (ISEs), which is so called the electronic tongue (E-Tongue) system. We apply the Fuzzy C-means (FCM) algorithm combined with Principal Component Analysis (PCA), which can be used to reduce multi-dimensional data to two- or three-dimensional data, to classify visually data patterns detected by E-Tongue system. The proposed technique can be determined the cluster centers and membership grade of patterns through the unsupervised way. The membership grade of an unknown pattern, which does not shown previously, can be visually and analytically determined. Throughout the experimental trails, the E-tongue system combined with the proposed algorithms is demonstrated robust performance for visual and quantitative analysis for different tastes in the liquids.

In this paper, we suggested and made a classifier or qualitative and quantitative analysis in urine analysis system. Input variable number and fuzzy membership function was made from determination of standard sample, and the fuzzy rules were determined by the analysis of spectroscopic properties of pads in strip. Fuzzy classifier used in urine analysis system was evaluated or the standard samples in each items and degrees. Negative and positive response of urine test was classified in good property, but detail classification or quantitative analysis had 8% maximum error in each items. If fuzzy membership unction and generation of rule are supplemented, suggested fuzzy classifier can be applied to the clinical test.

Purpose - The purpose of this research is to investigate the determinants of bakery revisit intention. This research selects Paris Baguette as the research context because the market share of Paris Baguette was the highest in Korean bakery market. Design/methodology/approach -This research employed revisit intention as the dependent variable, while this research chooses six attributes to account for revisit intention. Six attributes are price fairness, taste, product variety, accessibility, display, and membership. This research uses survey as the main instrument. For the data collection, online survey using Google survey form was implemented. The survey participants are domestic consumers of Paris Baguette. The number of observation is 245. For the data analysis, this study used frequency analysis, correlation matrix, exploratory factor analysis, reliability analysis, and multiple regression model. There are four control variables, which contains age, gender, visiting frequency, and monthly income. Findings - The results shows that price fairness, taste, product diversity, and accessibility are significant attributes with the positive effect. Among the significant attributes, taste presented the highest magnitude to explain the revisit intention. However, membership and display appeared as non-significant attributes to account for bakery revisit intention. Research implications or Originality - This study provides the bakery managers with the information to design their service and product. This study also contributes to the literature by understanding the consumer behavior more in the domain of bakery service.

M&A 과정, 특히 인수 후 통합에 관한 기존의 연구는 내부 조직의 통합에 중점을 두어 왔는데, 본 연구는 백화점 간의 인수합병 과정에서 브랜드 네임 및 회원 제도의 통합 사례에 대한 분석을 통해 양사의 브랜드와 고객의 통합 과정이 어떻게 이루어지며, 그 과정에서 무엇이 중요한지를 보고자 하였다. 본 연구는 유통학문의 연구방법론 중 규범적 연구방법론이나 경험적 분석기법에 적용되는 사례연구의 접근법을 적용하여, 인수합병을 통해 두 회사의 브랜드 네임과 회원 제도를 통합한 기업을 선정하여 분석하였다. 연구 결과, 인수합병 과정의 브랜드와 고객 측면의 통합을 위해서는 양사의 브랜드 및 고객 관리 현황에 대한 이해를 바탕으로 주요 통합 영역을 설정하여 고객과 기업의 양쪽 측면에서 의사결정을 고려해야 한다는 것, 통합의 목표를 단기적인 사업 효율성 추구가 아니라 장기적인 브랜드 파워와 구체적인 시너지 등으로 추구해야 한다는 것, 브랜드의 통합과 회원 제도의 통합은 사업 전략과 마케팅 프로그램 등의 변화를 유발하기 때문에 구체적인 후속 프로그램이 필요하다는 것을 알 수 있었다. 본 연구는 단일 기업을 대상으로 한 서술식 사례 연구라는 한계가 있어, 향후에는 복수 기업들의 비교분석적 연구나 브랜드 및 고객 통합 관련 이론들을 체계적인 분석의 틀로 이용하는 연구 등이 필요할 것이다.

In Human Reliability Analysis(HRA), the uncertainties involved in many factors that affect human reliability have to be represented as the quantitative forms. Conventional probability- based human reliability theory is used to evaluate the effect of those uncertainties but it is pointed out that the actual human reliability should be different from that of conventional one. Conventional HRA makes use of error rates, however, it is difficult to collect data enough to estimate these error rates, and the estimates of error rates are dependent only on engineering judgement. In this paper, the error possibility that is proposed by Onisawa is used to represent human reliability, and the error possibility is obtained by use of fuzzy reasoning that plays an important role to clarify the relation between human reliability and human error. Also, assuming these factors are connected to the top event through Fault Tree structure, the influence and correlation of these factors are measured by fuzzy operation. When a fuzzy operation is applied to Fault Tree Analysis, it is possible to simplify the operation applying the logic disjuction and logic conjuction to structure function, and the structure of human reliability can be represented as membership function of the top event. Also, on the basis of the the membership function, the characteristics of human reliability can be evaluated by use of the concept of pattern recognition.
