The demand for health care has increased with the development of global technology and the rise of public health awareness, and smart service systems have also been introduced to medical care to relieve the pressure on hospital staff. However, the survey found that patients’ willingness to use smart services at the time of consultation has not improved. The main research purpose of this study was to understand the willingness of patients from various groups to use smart medical service systems and to explore the influencing factors on patients’ use of smart service systems in hospitals through the technology acceptance model. This study distributed questionnaires in the outpatient area of National Taiwan University Hospital Yunlin Branch, and a total of 202 valid questionnaires were obtained. After related research and regression analysis, it was found that patients paid more attention to the benefits and convenience brought by smart services. If patients believed that smart services were trustworthy and beneficial to themselves, their usage intention and attitude would be positive. The results of this study are summarized by the following four points: (1) Designed according to the cultural conditions of different regions; (2) think about design from the patient’s perspective; (3) strengthen the explanation and promotion of smart services; and (4) add humanized care and design. This study could be used as a reference for hospitals to improve their service quality and systems in the future.

According to the 2011 research report of the Food and Agricultural Organization (FAO) of the United Nations, one-third of the world’s edible fruits and vegetables are wasted every year, totaling about 1.3 billion metric ton. A source of such waste is ugly fruits and vegetables, which have the same nutritional value as that of normal fruits and vegetables, but are discarded due to poor appearance for selling. If consumers can rediscover their value, it will be one of the ways to change food waste. This study first explored related topics through the literature; then, it drew up an interview outline, obtained and ranked the key success factors for the evaluation indices through education and interviews with industry professionals, and summarized the key success factors of marketing ugly fruits and vegetables through questionnaire and experts interview perspectives that targeted consumer groups as the questionnaire respondents. The conclusion of the study provides suggestions for enterprises to innovate service marketing through the blueprint of service design, which hopes to reduce food waste and maintain a balance with the environment, in order to achieve the goal of environmental sustainability. The results show that if consumers understand the relevant issues and pay attention to the truth of vegetable and fruit production, they can use their consumption power to protect their own and environmental rights. However, the trust between producers and consumers requires strengthening. Reducing the unnecessary waste of food and labor is expected to create more ecological and environmental consumption patterns in the future.

Taking Type 2 diabetes as the research object, and through questionnaire interviews, this study sought to determine the degree of satisfaction of patients with different attributes with medical services according to the distribution of demographic variables. Finally, the statistical results were taken as the reference basis for medical personnel to provide care to patients. Regarding the questionnaire survey, the questionnaire items were designed through face-to-face interviews aiming at their medical treatment process, thus, patients could truly reflect their feelings. This study used the SPSS statistical software (IBM, Armonk, New York, NY, USA) for analysis, and the results show that: (1) Patients of different genders had different degrees of satisfaction with medical services. (2) The difference in age, monthly disposable income, occupational category, and education level had no significant effect on service satisfaction. (3) The research subjects were all on the high side regarding their satisfaction with the service provided by medical facilities. This study is a pilot study, and it is hoped it will be used as a guideline for improving patient care quality in the future, thus, reducing the occurrence of diabetic complications through better medical care. The long-term goal is to continuously improve care and medical service quality, thus, reducing the waste of medical resources.

Consider a weighted directed acyclic graph $G$ having an upward planar drawing. We give a formula for the total weight of the families of non-intersecting paths on $G$ with any given starting and ending points. While the Lindstr\"om-Gessel-Viennot theorem gives the signed enumeration of these weights (according to the connection type), our result provides the straight count, expressing it as a determinant whose entries are signed counts of lattice paths with given starting and ending points.

The density of convenience stores in Taiwan is the highest in the world. Among the numerous commodities, the market competition for fresh food products is the fiercest and has become a focus of convenience store operations. Due to the change in Taiwanese lifestyles and consumer acceptance of the dining-out model, the demand and supply of fresh food products in convenience stores continues to increase. To benefit marketing performance, not only do convenience stores carry out promotional activities by reducing the price of products but they constantly innovate the taste and variety of fresh food products. For example, the tide of Taiwanese bento, during which promotions were implemented in the President Chain Store, has changed consumer diet habits; despite the raised price, consumers are still willing to purchase the product. However, convenient, real-time fresh food brought by this convenience store usually causes a massive waste of food. In its manufacturing and production processes, the food production chain ranks among the top three for national greenhouse gases. Whenever a piece of food is wasted, greenhouse gases are produced. Moreover, more resources are consumed to dispose of the wasted foods and garbage, further increasing greenhouse gas emissions and multiplying the carbon footprint. The phenomenon of excessive food waste has become an urgent issue in recent years in Taiwan, which is famous for its convenient food culture and service. In addition, because of Taiwan's special economic development status, as well as rapid urbanization and family structure change, the ways to jointly affect this special consumption and food culture have become a topic worthy of discussion. Therefore, this research selected cooked food products in convenience stores as the main subject to explore the effect of social status and diet consumption from the perspective of daily social patterns and family structure data. It also examined the dilemma of excessive waste of food, to provide improvement advice as a reference to future relevant social policies and research.
