  • Based on the government's willingness to commercialize UAM with the goal of 2025, it is making remarkable achievements in various fields, including the development of UAM. In addition, based on the concept of UAM, it is evolving into an Advanced Air Mobility(AAM) concept that includes commercial operation between long-distance or short-range cities, cargo delivery, public services, aviation tourism, and personal/leisure aircraft. however, research on physical problems such as low-altitude operation characteristics, speed within three dimensions, and dizziness caused by external environment has yet to be found. Therefore, in this study, actual images are taken while flying at the expected altitude and speed of UAM using a helicopter, and by experiencing it to the general public using a UAM simulator equipped with VR and Motion, physical reactions such as fear and dizziness of passengers that may occur during actual UAM operation of UAM are analyzed.

  • Parcel service is to deliver goods from one place to the designated destination requested according to user request. Parcel operations such as sorting, distributing, etc. or the managed information are heterogeneous by the companies. Additionally, it is impossible to support interoperability between companies with unformatted data of manual processing. Most parcel package boxes attached to paper typed waybill is attached is delivered to consignee. So, security problems such as personal information leaking are occurred, or extra processing time and logistics costs are needed due to wrong or the damaged information. Business environment of parcel service is rapidly changed as introducing unmanned delivery or the advanced technology such as Internet of Things. User want to know the accurate status or steps from parcel service request to delivery. To provide these requirements, the unified and integrated waybill information for reliable transportation of parcel service is needed. This information will provide to pickup or delivery carrier, warehouse or terminal, and parcel service user per pickup, transport, and delivery stage of parcel delivery service. Therefore, this paper defines the simplified and unified information model for parcel service waybill by analyzing information systems used for logistics unit processes that is occurred to parcel service, and manual work processes, and developing the relevant information of work flows occurred between business processes or transactions with the collected or processed information by from parcel service's stages. It is possible to share these standard model between business entities, and replacing paper typed waybill will improve national life safety as preventing security threats by paper typed waybill. As a result, it will promote the public interest from the stakeholder's perspective.

  • Dietary life style of the elderly living in rural areas of Gyeongbuk Andong during the busy farming season was surveyed and a monthly meal plan for the elderly was developed using eco-friendly native crops and considering the characteristics of a busy farming season and their preferences. A week meal plan was selected and applied to those fields. The meal plan was developed for an elder's house in Gyeongbuk Andong during the busy farming season. Especially, to increase the intake of calcium and dietary fiber, bamboo sprouts, pepper leaves, dried slices of whitebait, and fried anchovies were used. Considering the busy farming season, the ginseng chicken soup and the soybean noodle soup were served to provide high quality of protein and to improve health condition. A cold soup of cucumber and brown seaweed was used to supplement liquid, vitamins, and minerals. The results are as follows: the highest score of the preference on a staple was 8.77 for the boiled barley of menu 5; the favorite soup was the ginseng chicken soup (8.73) in menu 4; for side dishes, those in menu 5 were most popular (8.69); the favorite meal was the ginseng chicken soup of menu 4 (8.69). Regarding the amount of leftover foods, the lightest was 30.14 g in Gyeongbuk Andong menu 3 which significantly indicates high preference (p<0.05). The current study was a planned meal service menu using local crops and seasonal foods, which was actually applied to the field resulting in high preference and satisfaction levels.

  • In this study, the breads with medicinal herbs (MH) composites showing immunostimulating activity were prepared and their characteristics were examined. Fourteen kinds of medicinal herbs were extracted with hot water and divided into 3 groups (MH-1, MH-2, MH-3) based on their contents. All groups showed immunostimulating activity in terms of macrophage phagocytosis, nitrite production, cytostatic activity and cytokine production. In the preparation of breads containing MH extracts of various contents (0, 30, 50, 70, and 100%), there was no significant difference among dough pHs of all groups after first fermentation, but loaf volume was significantly (p<0.05) increased in 70% added group while decreased in 30%, 50%, and 100% added groups compared to the control. The "a" and "b" values of bread crumb increased with the content of MH extracts while "L" value decreased, but these values of bread crust were similar to the control group. Most improvements in hardness, adhesiveness, gumminess and chewiness of bread were noticed by the addition of 70% MH extracts, but those of springiness, cohesiveness and resilience were mostly by the 50% addition ones. Through the sensory evaluation, it was revealed that mouth feeling, taste and overall preference decreased at breads containing 70% and 100% extracts, although appearance and crumb texture were not significantly (p<0.05) different among all groups.

  • This study examined the causal relationship between work environment and job satisfaction/turnover intention through statistical analyses using the statistics programs SPSS(18.0) and AMOS(18.0) of over 268 business owners operating small sized Chinese restaurants in the Busan and Gyeongnam area. Research results found that among the business owners of small sized Chinese restaurants, 130 were owner/chefs (48.5%), 63 engaged in hall serving (23.5%), and 75 were in delivery (28.0%). It was also found that while the physical environment had a positive effect on work pride and economic satisfaction, sale stress had no effect on work pride and economic satisfaction. In addition, the physical environment and mental labor environment showed a positive effect (+) on turnover intention, although job satisfaction (work pride, economic satisfaction) showed a negative effect (-) on turnover intention. Such result leads to the conclusion that for business owners of small sized Chinese restaurants, sale stress experienced during the course of business serves as a factor weakening job satisfaction while increasing turnover intention to a greater extent of the physical environment (kitchen facilities and hall facilities). Thus, it seems that practical business training, such as service training, is a greater necessity for business owners of small sized Chinese restaurants, as opposed to an improvement of restaurant facilities.

  • In a buyer-seller transaction process, 'value for money,' a measure of quality-price-ratio, is one of the most important criteria for buyers' purchasing decisions. The purpose of this paper is to suggest a method which helps online shoppers choose the best of several sellers offering homogeneous goods. We suggest FDH (free disposal hull) model, an applied model of data envelopment analysis (DEA), for online buyer-seller transactions and verify it with the data from an Internet comparison shopping site. For this purpose, we analyze consumer choice behaviors by examining how consumers respond to different sale conditions such as price, brand, or delivery time. Then, we implement a seller recommendation system to support buyers' purchasing decisions. We expect our FDH model to provide valuable information for rational buyers who want to pay the least price for high quality products/services and to be used in implementing automated evaluation processes in micro transactions. Moreover, we expect that our results can be utilized for sellers' benchmarking strategies which help sellers be more competitive by showing them how to attract buyers.

  • In this study, we conducted a questionnaire survey for the purpose of finding a method of mobile sector ecosystem activation targeted at small and medium businesses (SMBs). Through the total of 204 responders consisting of business employees from each mobile sector, we analyzed the factors inhibiting the development of the mobile ecosystem and preventing the activation the mobile market, as well as conducting a diagnosis of the digital potential. This paper presented suggestions for searching for a systematic supporting strategy considering the short-term inhibitory factors (market structure improvement, financial support, etc.) and long-term orientation factors (personnel nurturing, strengthening of supporting role by governmental initiative) for the activation of the domestic mobile market. After measuring the digital potential, we found that domestic mobile SMBs have perceived the importance of the digital potential and have considered and readied themselves for the future market. The present survey found that if suitable digitalization can be accomplished for their firms' products and services, they have the ability and willingness to succeed in the market. However, they have a hard task ahead of them from adigital delivery perspective given the potential for digital disruptions.

  • Purpose: This study evaluated the effects of nutrition management application in a mobile device on obesity management of patients with breast cancer. Methods: Fifty subjects, who were breast cancer survivors, aged 30 years and older, participated in an obesity management program for four weeks. They were divided randomly into two groups: a control group (n = 25) and a treatment group (n = 25). The treatment group was provided an application for nutrition management and diet consultant, while the control group maintained their ordinary life without any nutrition management. Results: The weight of the treatment group decreased by 0.8 kg, but the change was not significant. In contrast, the waist-hip ratio of the treatment group decreased significantly from 0.75 to 0.71 (p = 0.012). The Nutrition Quotients of the treatment group increased significantly from 61.3 to 69.6 points (p < 0.001), whereas that of the control group decreased significantly from 61.5 to 59.0 (p = 0.002). Conclusion: This mobile nutrition management application for breast cancer patients is effective in managing obesity and dietary habits. These results can be used as basic information to prepare an obesity management program for breast cancer patients.

  • 최근 아동들 사이에서 칼로리가 높고 간단하게 먹을 수 있는 인스턴트식품이나 패스트푸드 등의 섭취가 증가하는 경향과 함께 비만 등 영양적인 문제점이 크게 부각되고 있다. 특히 아동기는 식습관 형성에 중요한 시기이므로 올바른 식품선택은 무엇보다 중요하다고 볼 수 있다. 본 연구는 초등학교 학생들의 올바른 식생활문화를 형성하기 위한 자료로 활용하고자 평택 초등학교 2개교의 4, 5, 6학년 300명을 대상으로 패스트푸드 섭취실태를 조사하였다. 평균연령은 11.7세, 키는 141.5cm, 몸무게는 36.7kg이였다. 아침 식습관태도 조사에서는 일주일에 5번 이상 아침식사를 한다(여학생 78.1%, 남학생 74.3%)는 답이 가장 많았다. 아침결식 이유는 밥맛이 없기 때문(여 58.2%, 남 54.4%)이 가장 높은 비율이었고, 편식은 여학생의 54.2%, 남학생의 48.9%가 하지 않는다고 하였으나, 편식하는 식품은 나물이나 샐러드 등의 채소류(여 51.1%, 남 61.4%)가 많았다. 간식섭취는 가끔 섭취한다는 답이 여학생 59.8%, 남학생 60.0%로 높은 비율을 나타냈다. 간식은 부모님이 사주신다(여 32.6%, 남 39.1%)고 하였으며, 여학생은 50.5%가 가족과 함께 먹고 남학생의 경우에는 44.8%가 혼자 먹는다는 결과를 보였다. 간식으로 과일섭취가 이루어지고 있는지 조사한 결과는 여학생의 33.0%가 2-3일에 2회 이상 섭취한다고 했지만, 남학생은 29.5%가 매일 먹는다고 답을 하여 과일섭취는 모두 딸이 하고 있음을 알 수 있었다. 패스트푸드의 이용동기는 맛이 좋아서(남 60.8% 여 55.2%), 다음은 이용이 편리하기 때문이며(남 32.4% 여 40.6%), 주로 이용하는 곳은 분식 및 편의점이었다. 패스트푸드 이용횟수는 월1-2회(남 52.4%, 여 51.6%)가 가장 많았으며, 다음이 주1회 정도(남 21.9%, 여 32.0%) 이용한다고 하였다. 이용시간은 방과 후 저녁시간을 가장 많이 이용하며(남 47.6%, 여 50.5%), 남 녀 모두 사서 집에서 먹거나(남 44.7%, 여 41.2%), 배달시켜 집에서 먹는다(남 39.8%, 여 37.1%)고 하였다. 가장 좋아하는 패스트푸드는 라면 등의 분식으로 여학생의 40.2%, 남학생의 26.2%가 해당되었고, 그 다음 순서로 남학생은 피자(22.3%)와 치킨(22.3%) 및 햄버거(18.5%), 여학생은 치킨(25.8%)과 도너츠(12.4%)를 더 선호하였다. 패스트푸드 만족도를 3점 척도로 조사한 결과, 맛이 가장 높은 점수(2.42)였으며, 가격(1.98), 위생(1.92) 서비스(2.15)는 보통으로 평가했다. 본 연구 결과, 조사 대상자들의 패스트푸드 섭취는 가끔 먹는 간식과 같은 형태로 당장 우려할 정도는 아니지만, 선행연구에서 보고된 바와 같이 10대와 20대에 특히 섭취율이 증가함을 감안할 때, 중학생이 되기 전 단계에서 우리음식의 우수성과 패스트푸드 섭취지양에 대한 교육이 필요하다고 본다.
