병렬처리로 구현한 자기조직화 신경망을 이용한 정규혼합분포의 추정

안성만,이철희 한국지능정보시스템학회 2011 한국지능정보시스템학회 학술대회논문집 Vol.2011 No.12

본 연구에서는 자기조직화 신경망이 필요한 노드만을 가지고 최적화하여 정규혼합분포를 추정하는 모형(안성만, 2011)을 Java언어에서 제공하는 스레드(Thread)를 기반으로, 멀티코어컴퓨팅환경에서 병렬처리방식으로 구현하여 순차처리방식에 비해 짧은 연산시간으로 정규혼합모형의 추정이 가능함을 보이려고 한다. 안성만(2011)이 제안한 모형은 개념적으로는 병렬처리가 가능한 것으로 보이지만 실제 병렬처리로 구현하려면 혼합비율의 조건부 기대값을 매번 수정해야 하는 문제로 인하여 각 병렬처리 노드가 독립적으로 실행되지 못하는 문제가 있다. 이 문제를 고려하여 본 연구에서는 병렬처리 방법론을 제안하고 그 성능을 평가하였다. 병렬처리 방법론은 Java의 멀티스레드를 이용하여 구현되었으며, 모의실험을 통하여 제안한 모형이 기대한 결과를 얻음을 확인하였다.

안성만,이재한,김은정 한국프랜차이즈경영학회 2018 프랜차이즈경영연구 Vol.9 No.1

Purpose – In franchise system, how to build the relationship between the franchisor and franchisee through influence strategy is very important, because it affects on the long-term orientation like recontract intentions. Thus, this study examines the effect of mandatory influence strategy on relationship satisfaction, relationship trust, and recontract intentions in the context of food-service franchise industry. This study suggests the guidelines on how franchisor uses their influence strategy on franchisee to maintain and increase the recontract intentions. Research design, data, and methodology - This study examines the structural relationship between mandatory influence strategy, relationship satisfaction, relationship trust, and recontract intentions from the franchisee's perspective. Mandatory influence strategy divide into three sub-dimensions such as request, legalistic plea, threat. In order to test the purposes of this study, research model and hypotheses were developed. Every constructs were measured by multiple items tested and developed in the previous research. Also, the constructs utilized in this research are measured using 7-point scales anchored by “1=strongly disagree” and 7=strongly agree“. The data were collected from 496 owner and owner manager franchisees and were analyzed using SPSS 21.0 and Smart PLS 3.0. program. Analysis of frequency was conducted to identify the demographics and general characteristics of the survey subjects. In order to measure the reliability and validity of the measurement tools, confirmatory factor analysis and correlation analysis were conducted and structural model analysis was conducted to verify the proposed research model. Result – The results of this study are as follows. First, this research found that mandatory influence strategy is positively related to relationship satisfaction and relationship trust, but not to recontract intention directly. Second, this research also found that the full mediating role of relationship satisfaction and relationship trust between the mandatory influence strategy and recontract intention. Conclusions – The findings of this research indicate that franchisor should use properly mandatory influence strategy to improve recontract intentions through relationship satisfaction and relationship trust. Due to the nature of food-service franchise industry, which needs high relationship quality, franchisor must manage their franchisee using influence strategy in order to improve satisfaction and trust. If franchisee perceives higher relationship quality, they will show higher intention to recontract. At the end of this paper, limitations and future research directions were suggested.

Effects of Foodservice Franchise’s Online Advertising and E-WOM on Trust, Commitment and Loyalty

안성만,양재장 한국프랜차이즈경영학회 2021 프랜차이즈경영연구 Vol.12 No.2

Purpose: One of the characteristics of service companies such as foodservice franchise is that it is easy to imitate, so many brands can imitate the menu that is popular with consumers. Therefore, foodservice franchise company should develop a brand that customers can identify from other brands in order differentiate it from its competitors. In order make the foodservice franchise company identifiable from other brands, it is possible through communication with customers. Therefore, this study proposes a new research model to analyze customer loyalty through online advertising and online word of mouth trust and immersion. Online was provided to customers through a mixture of advertisements and word of mouth, but previous studies have only considered online advertisements or online word of mouth. In addition, we want to verify the difference according to gender, which is an important variable in researching the online information processing behavior of customers. Research design, data, and methodology: The questionnaire of this study was surveyed on 20 years of age or older who have visited the restaurant franchise store within the last 3 months among the foodservice franchise companies operating SNS. During the survey period, 400 surveys were surveyed for a total of 20 days from April 1 to April 20, 2020. Result: The research results are as follows. First, in this study, the effect of online advertisement and online word of mouth on trust and immersion was studied. Second, this study verified the social influence theory in online advertising and online word of mouth. Third, the effect of online advertising and online word of mouth on loyalty according to gender was verified. Fourth, compared to existing advertisements, online advertisements are suitable for marketing by foodservice franchise companies because they can interact with consumers, modify advertisements immediately, execute extensive advertisements at low cost, segment the market, and measure advertisement effectiveness. The recent online expansion has been expanded to mobile-based, allowing foodservice franchisees to provide new communication services such as SMS (Short Message Service), multimedia messaging services, and location-based services. Fifth, a foodservice franchise company can increase brand awareness through online marketing or induce the use of offline stores. Sixth, franchisor can grow into a sustainable company only when they use resources efficiently. Conclusions: Trust is important in foodservice franchise information. This trust has a significant impact on customer commitment and loyalty.

데이터마이닝기법을 이용한 주식시장의 이상매매 적출

안성만,홍정훈,위경우 한국지능정보시스템학회 2006 지능정보연구 Vol.12 No.4

In this paper, we discuss a data mining approach to detection of stock price manipulation in the Korean stock market. First of all, we review current methods which is being exercised in the Korean stock market as well as in the US stock market. And then we apply data mining techniques to the problem using data from the Korean stock market and discuss the results along with their implications. 본 논문은 증권거래소 이상매매 적출업무의 효율성을 제고하기 위해 데이터마이닝 기법을 적용하는 방안에 대해 연구하는 것을 주된 목적으로 한다. 이 과정에서 국내 증권거래소의 이상매매 적출모형과 데이터마이닝을 활용한 해외사례로서 미국 NASD의 ADS를 소개한 뒤, 실증분석에 사용될 자료들을 시세조종 종목과 정상 종목으로 나누어 검토한다. 국내에서 주식시장의 이상매매 적출에 대한 데이터마이닝 기법의 적용에 대한 연구가 없는 상황에서 다양한 입력변수를 만들어 실제로 데이터마이닝 기법들을 적용하여 적출성과를 상호 비교한 결과와 시사점을 기술하였다.

회전원판 반응조를 이용한 Pseudomonas sp. KS-96에 의한 gallic acid로부터 Pyrogallol의 전환

안성만,김동석,정영기,임복규,이홍수,류병호,An, Seung-Man,Kim, Dong-Suck,Jeong, Young-Kee,Lim, Bock-Gu,Lee, Heung-Su,Ryu, Beung-Ho 한국생명과학회 1997 생명과학회지 Vol.7 No.2

Gallic acid로부터 pyrogallol로 전환하는 균주를 토양에서 분리 동정하여 얻는 Pseudomonas sp. KS-96의 균체를 회전원판 반응조에 고정화시킨 후 연속전환을 시도하여 다음과 같은 결과를 얻었다. Gallate decarboxylase의 활성은 배양 24시간에서 가장 좋았다. 반응조의 원판에 gallic acid가 함유된 액체 배양액을 시간당 20m${\ell}$씩 공급하면서 균체막의 두께가 steady state에 도달할때까지 공급하였다. 균체를 고정화 시킨 후 시간 경과에 따른 전환율은 18시간부터 36시간에서 전환율이 높았다. 균체 고정화 후에 gallic acid를 15g/${\ell}$ 함유하는 기질을 시간당 30m${\ell}$씩 주입했을 때 pyrogallol의 전환율이 가장 좋았으며 회전원판 반응조에 의한 연속적 전환은 6일에서 8일까지가 각각 81%, 80%로서 가장 높았다. In previous paper Pseudomonas sp. Ks-96 isolated from the bioconversion into pyrogallol from gallic acid . Continuous bioconversion of pyrogallol was carried out using rotatory disc contactor immobilized Pseudomonas sp. Ks-96 . Enzyme activity of gallate decarboxylase released from Pseudomonas sp. Ks-96 were shown at the highest activity on 24h incubation. Culture media containing gallic acid supplied on the flow rate of 20m${\ell}$/h until thickness of cells wall reached steady state. Bioconversion rate of pyrogallol from gallic acid showed at highest level ranging from 18hr to 36h according to time courses. Continuous bioconversion of pyrogallol using rotating disc contactor was about 82% and 80% between 6 and 8 days at the feeding rate of 300m${\ell}$ per hour in the medium containing 15g/${\ell}$ gallic acid.
