Purpose - In align with the increasing competition in both online and offline franchise markets caused by the increasing impact of social networking service, entrepreneurial passion(EP) of the franchise owners has crucial impact on the stakeholders. This study proposed the customer among stakeholders has the critical influence firm's success and examined the structural relationship between entrepreneurial passion(EP) and trust, identification, and loyalty from the customer's perspective. Research design, data, and methodology - This study examines the structural relationship between entrepreneurial passion(EP), trust, identification, and loyalty from the customer's perspective. More specifically, the EP were measured using three sub-dimensions such as EP-inventing(Perceived passion for inventing), EP-founding(Perceived passion for foundting), and EP-developing(Perceived passion for developing). In order to verify the research purposes, research model and hypotheses were developed. All constructs were measured with multiple items developed and tested in the previous studies. Each item was measured on a 7 point Likert-scale anchored by '1 = strongly disagree, 7 = strongly agree'. The data were collected from 449 franchise consumers through online survey and were analyzed using SPSS 21.0 and Smart PLS 3.0. statistical program. Result - The results of this study are as follows. First, EP-inventing and EP-developing have significant impacts on corporate trust. Second, EP-founding does not have significant impact on corporate trust. Third, EP-inventing and EP-founding have significant impacts on consumer identification. Fourth, EP-developing does not have impact on identification directly, but does indirectly through corporate trust as a mediator. Fifth, corporate trust and identification have significant impacts on loyalty. Conclusions - This indicates that the foodservice franchise CEOs should continuously develop new menus and service to fulfill customer needs. EP-inventing of the food franchise CEOs may enhance customer trust for higher quality of product or service, and EP-developing can also be a driving force for customer trust as it embeds belief in customers that the franchise is sustainably developing. Also, food franchise CEOs should first clarify the support process for the existing brands before developing new ones. Customers tend to lead the trend by using brands that satisfy new trends in the foodservice franchise market, and it could have identification with the trend-setting franchise. Customers do not accept if a company is different from their personal image or norms. So the franchise CEOs must create identification with customers by building corporate trust. Corporate trust influences consumer behavior and emotion, thus the franchises need to secure trust by improving product or service continuously.

Purpose - Recently, the food service franchise market is experiencing rapid growth and competition is intensifying. Therefore, consumer choice has expanded, and reputation management has become important as a strategy for survival of corporations. Based on previous studies, this research proposed the theoretical framework about the structural relationships among reputation, trust(cognitive trust, affective trust), and loyalty. Research design, data, and methodology - This study examined the structural relationship between reputation, trust, and loyalty from the customer's perspective. Based on comprehensive validation procedures across nine food service Franchise firm types, This study found support for a five-dimensional scale with the following dimensions: Customer Orientation, Employer Brand, Reliable and Financially Strong Company, Product and Service Quality, and Social and Environmental Responsibility. In order to verify the research purposes, research model and hypotheses were developed. The data were collected from 227 food service franchise consumers through online survey. The data was analyzed with SPSS 24.0 and Amos 23.0 statistical program. Result - The results of the study are as follows. First, customer orientation, reliable·financially strong company and product·service quality have significant impact on corporate cognitive trust. And employer brand, product/service quality and social·environmental responsibility have significant impact on corporate affective trust. Second, cognitive trust and affective trust have significant impacts on consumer loyalty. Conclusions - The implications of this study are following as: From the theoretical perspective, this study considers trust as two dimensions such as cognitive and affective, not a single dimension, and identify what dimensions of franchise firms affect consumers' reputation perception and in turn lead cognitive and affective trust, and loyalty. This study also provides several managerial implications. In the franchise market where competition is intensifying, it is very important to analyze the attitudes of consumers in order to gain an advantage in competition with other competitors. In this study, it is meaningful that the study was conducted on consumers who have experience using a restaurant franchise company. Also, reputation is necessary to pay attention to the company because it is an important variable that strengthens with customer through confidence in food service franchise business, and leads loyalty and consumer consumption. Therefore, marketers should develop marketing strategies considering various reputation factors.

Purpose - Turnover Intention in the franchise industry is becoming a very important issue. This study examines the structural relationships between organizational justice, emotion, job satisfaction, and turnover intention in the franchise industry. In this model, emotion was classified into two sub-dimensions such as positive and negative emotion. Research design, data, methodology - The sample of this study collected from employees of a food-service franchise company is representative. Copies of the questionnaire along with a cover letter were delivered by a research assistant to the human resources manager or the general manager of the selected food-service franchise firms after they agreed to participate in the study. In order to increase the response rate of the respondents, a small gift was provided to the respondents who completed the questionnaire. A total of 300 questionnaires were distributed and 285 returned responses, 9 responses were not usable due to missing information. Thus, a total of 276 responses were used using structural equation modeling with Smartpls 3.0. Results - The results showed that organizational justice had positive significant effects on positive emotion and job satisfaction. Job satisfaction had negative a significant effect on turnover intention. And negative emotion had positive significant effect on turnover intention. Conclusions - The results of this study provide some implications. If employees feel that the franchise headquarters is fair about the methods and procedures of decision making, resource allocation, information sharing, etc., it means that employees feel better. If the franchise's decision-making processes and methods and results are transparently disclosed and processed in accordance with the internal rules of the company, the employees will be able to fully understand and accept them. The results of this study also show that positive and negative emotions of service-based franchise employees have different effects on job attitude and organizational behavior. In particular, when negative emotions of employees are passed on to others and the results are negative, employees may feel that they are disoriented or wrong. Therefore, the franchise headquarters should try to inspire employees' sense of organizational community, and should pay attention to how to relieve the job stress and the fair distribution of work and rewards.

The purpose of this study was to determine the level of toothbrush bacterial growth, whether the dryness of the toothbrush head differs depending on the number of holes in the head, and to use these results as a reference for future toothbrush design. Two-millimeter holes were created on the head of the toothbrushes in groups of three, one, or zero holes. We made the solution with Streptococcus mutans, and the toothbrushes were placed in the solution and agitated. The toothbrushes were shaken to remove moisture and allowed to air-dry. The toothbrush heads were swabbed with saline and then placed in two inoculation groups. The first group was inoculated with a 102 dilution of the S. mutans culture and the second was inoculated with the original culture. After incubation, bacterial colony numbers were measured. The number of holes on the toothbrush head correlated with a decrease in number of cultured bacterial colonies. Our model of a toothbrush head with holes indicated that these holes in the toothbrush head were effective in reducing the level of microbial contamination and that a greater number of holes creates an improved toothbrush sanitation effect. The average number of colonies on the head of toothbrush by number of holes was high, followed by the number of holes 0, 1 and 3, and the average number of colony among toothbrush heads was same. The use of a toothbrush with holes between the toothbrush head indicates that it is effective in reducing the level of microbial contamination between the toothbrush head and toothbrush and the higher the number of holes, the better the effect.

The purposes of this study were as follows. First is to compare the importance of operational factors to determine types of school breakfast program, and second is to do the preference analysis of operation-related people depending on the attributes and levels of the operation of school breakfast program. The questionnaires developed for this study were distributed to 134 school dietitians, 114 school foodservice officials at the educational board, 68 staff members of foodservice contractors and 493 parents. Statistical data analyses were performed using SPSS/WIN 12.0 for descriptive statistics and conjoint analysis. The conjoint design was applied to evaluate the hypothetical foodservice types. According to the analysis on the attributes and levels of the school breakfast operation, the relative importance of each attribute was as followsprice (36.30%), menu (29.60%), foodservice staff (22.54%), serving type (11.55%) to school dietitians, price (34.99%), menu (28.15%), foodservice staff (23.52%), serving type (13.35%) to school foodservice officials at the educational board, menu (30.55%), price (30.24%), foodservice staff (28.75%), serving type (10.47%) to staff members of foodservice contractors and price (36.34%), menu (29.73%), foodservice staff (21.01%), serving type (12.92%) to parents. The results of the conjoint analysis indicated that the school dietitians and school foodservice officials at the educational board preferred the school breakfast operation program with 3 traditional menus and 2 convenience menus per 5 day, $1{\sim}3$ foodservice staff, with a price range of $1501{\sim}2000won$, and tray serving. Staff members of foodservice contractors preferred the school breakfast operation program with 3 traditional menus and 2 convenience menus per 5 day, $1{\sim}3$ foodservice staff, with a price range of $2501{\sim}3000won$, and tray serving. Parents preferred the school breakfast operation with 5 traditional menus per 5 day, $6{\sim}7$ foodservice staff, with a price range of $2501{\sim}3000won$, and tray serving. About a half of school dietitians considered that elementary schools were appropriate for the suggested school breakfast operation program. But, 68.2% of school foodservice officials at the educational board, 69.1% of staff members of foodservice contractors, and 38.1% of parents considered high schools to be the suitable model. Therefore, it indicated the need to recognize the different opinions among breakfast operation-related people and take these factors into consideration in developing the school breakfast program.

본 연구는 사회 자본에 대한 긍정적인 생각이 실제 한국 노인들의 사회 참여에 미치는 영향을 파악하기 위해 이루어졌다. 2003년 우리나라 사회통계조사 자료를 이용한 단면연구로 총 65세 이상 노인 8,586명이 대상이 되었다. 사회 참여에 대한 문항은 두 가지 문항으로, 단체참여, 자원봉사활동의 두 가지를 사회 참여로 정의하였다. 또한 사회 자본에 대한 긍정적인 생각은 빈부격차 감소, 범죄율 감소, 규제완화와 부패의 감소, 도덕성 수준의 향상, 환경오염의 감소 등으로 5가지로 정의되었고, 분석은 성, 연령, 결혼수준, 교육수준, 주택소유, 취업, 흡연, 음주, 활동제한일수, 와상일수, 기능제한과 자가평가 건강수준 등을 고려하여 분석하였다. 주요결과는 노인의 사회 참여는 사회 자본에 대한 긍정적인 생각에 의해 영향을 받으며, 사회 자본에 대한 생각이 다르면 이에 따라 다른 사회 참여의 양상을 보인다는 것이다. 빈부격차가 감소되었다고 생각하고 있는 노인은 사회 참여를 그렇지 않은 사람보다 더 많이 하는 것으로 나타났으며, 특히 단체 참여에서 그러하였다. 자원봉사활동에 있어서도 빈부격차가 줄었다고 생각하고 있는 경우와 환경오염이 줄었다고 생각하고 있는 경우, 도덕성 수준이 향상되었다고 생각하는 노인의 경우는 그렇지 않은 노인에 비해 각각 1.65배, 1.48배, 1.52배 더 자원봉사 활동에 참여하고 있는 것으로 나타났다. 앞선 연구들에서 언급하고 있듯 교육수준이 높을수록, 그리고 건강상태가 좋을수록 사회 참여를 더 활발하게 하는 것과 함께 사회자본에 대한 긍정적인 생각도 하나의 사회참여에 영향을 주는 요인이 될 수 있다. 사회 자본에 대한 긍정적인 생각을 가질 수 있도록 노력하는 것은 사회 참여를 더 하게 하여 노인의 건강을 증진시키는 하나의 요인이 될 수도 있을 뿐만 아니라 연령이 증가하면서 건강이 나빠지는 것을 보완할 수 있는 하나의 요인이 될 수 있을 것이다.

현 도로교통법상 도로 이용의 효율성과 교통안전 확보의 목적으로 차로 별 통행 가능 차종을 지정한 제도로써, 2020년 개정안이 현재 시행되고 있다. 독일과 국내의 자동차 1만 대당 교통사고 사망자 수를 비교하였을 때, 독일의 교통사고 사망자는 국내보다 현저히 낮은 수치를 기록하고 있다. 대표적으로 속도의 제한을 두지 않은 독일 아우토반의 사례는 한국의 속도위반법만이 사고율의 경감에 정답이 되지 않는다는 점을 시사한다. 아우토반 고속도로의 킵 라이트 원칙(keep right principle)에 따라 준수되는 지정차로제는 교통사고 감소에 큰 역할을 한다. 이러한 사실을 기반으로 지정차로제 위반 차량의 단속과 준수율 향상을 위한 교통 단속 시스템을 제안한다. 딥러닝 객체 인식 모델인 Yolo5를 이용하여 차종을 인식하고 OpenCV를 이용하여 차량 번호판과 차선을 인식 및 추출된 데이터를 서버에 저장하여 법규의 위반 여부를 판별하는 지정차로제 단속시스템을 개발한다. 이에 따라 운전자의 제도 인식 및 준수율의 향상을 통한 교통사고율의 감소 효과가 있을 것으로 기대된다.
