Door to door service is a typical method for individual parcel deliveries. In the current delivery information system, a delivery person manually inputs the information of many delivery results, which causes inefficiency and difficulties of tracking deliveries. This study suggests an enhanced delivery information system which has the following two characteristics. Firstly, a tagged RFID(Radio Frequency Identification) transmits the delivery result information to the main server by just collecting RFID at a place of destination. Secondly, with the characteristics of rewritable method, the collected RFID is to be input new information and tagged to other parcels.

Various project delivery methods have been utilized by owners over the years to maximize project performance. The design-build delivery method is being increasingly used due to the advantages it can offer to an engineering construction industry. Numerous studies have advocated the use of design/build over the traditional design/bid/build delivery approach. This study represents comprehensive analysis of 40 projects from the construction industry and shows that design/build method may not provide all the benefits to project performance. This study found timesaving was a definitive advantage of design/build project delivery, but the positive effects of cost changes was not convincing. Based on the results of the study, the project management expertise and experience of the contractor may have a greater impact on project performance outcomes than focusing on project delivery strategy only.

This study was formed to propose a theoretical background trying to create a positive delivery experience by understanding college women's subjective accounts (their view and attitude) on delivery. Method: Q- methodology was used to appreciate the highly abstract concept in an objective manner, since delivery can be assessed differently with each experience. Result: There were three types of opinions about the delivery in college women. The first type (matured type) understood delivery to be a precious experience that enables women to gain the value of life through labor pain, and granted then more appreciation to their own mothers. The second type (will type) recognizes delivery as an option rather than an obligation for women. They think women chooses whether or not to experience the process, especially since delivery requires a great deal of responsibility. The third type (positive type) takes delivery as a valuable, worthwhile, and marvelous process that they wish to experience. They are not even afraid of giving birth multiple times. Conclusion: The study explains and allows us to understand college women's overall opinion and attitudes about delivery. Thus this study aids the seizure of an opportunity to build a theoretical base for delivery management.

유치원과 초등학교 저학년의 교육에서는 학교와 학부모 사이의 유기적인 정보전달이 대단히 중요한데, 어린 학생들의 특성상 학생들을 중간매개체로 해서 학교와 학부모 사이의 정보를 전달하는 기존의 방법들은 신속하고 정확한 정보전달에 한계를 갖는다. 이에 본 논문에서는 인터넷 홈페이지와 휴대폰의 메시지 서비스를 결합한 학교와 학부모 사이의 정보전달 방법을 제안하고, 이를 반영한 정보전달 시스템을 설계 구현하였다. 본 논문의 제안방법과 구현시스템은 유효시간 내에 정보를 정확하게 전달하면서도 통신비용과 교사의 업무량을 크게 증가시키지 않는다.

This study was performed to provide fundamental data on the convenience foods purchase according to the food-related lifestyle. This study was conducted on 398 Chinese international students residing in Gyeonggi area between October and December 2019. Among the total 373 survey subjects, gender was 183 male students (49.1%) and 190 female students (50.9%). This study was conducted by questionnaire method with reference to previous studies. There are significant differences in economic pursuit and taste pursuit for delivery food use, economic pursuit and taste pursuit for delivery food information, health pursuit and taste pursuit in delivery food ordering method, and economic pursuit and convenience pursuit for delivery food use (p<0.05). Delivery food usage time was significantly different in convenience pursuit, health pursuit, eating out pursuit, and taste pursuit (p<0.05), and the delivery food preference menu was significantly different in economic pursuit, health pursuit, eating out pursuit, and taste pursuit (p<0.05). The menu positive factors among satisfaction factors showed statistically significant differences in economic pursuit (β=0.188, t=3.531) and health pursuit (β=0.160, t=3.099) among food related lifestyle factors. In conclusion, this study presented the desirable direction of delivery food usage in Chinese students.

Drones are now widely used in civilian applications such as filming, leisure, agricultural control, monitoring, and the generation of 3D-spatial information, deviating only from military drones. In the field of logistics, prototypes are emerging in the area of logistics transportation, and to develop a future transportation service under the name of a drone tax, each country is introducing its first flight results using its own unique drones. In this paper, we review the domestic and overseas trends of drone delivery service technology, which requires various capabilities such as automatic flight, and review the related core technologies. We then propose the flight capability and road map of a drone delivery service according to the detailed conditions such as the flight area, visibility, and flight method. Additionally, in connection with the postal processing of the Korea Post Office, which would be a main demand for this type of service, we describe a method for realizing a drone delivery service based on the structure, scenario, and deployment of the drone delivery system.

Purpose: The study was done to examine the effects of San- Yin-Jiao(SP6) acupressure treatment on subjective labor pain, length of delivery time in women during labor. Method: The study design was a randomized controlled clinical trial study using a double-blinded method. Data were collected using a structured questionnaire, a subjective labor pain scale and measurement of delivery time. The experimental group(n=29) was received SP6 acupressure and control group(n=29), SP6 touch for the duration of each uterine contraction, during 30 minutes after 3cm dilatation of cervical os. Result: The subjective labor pain scores was significantly different between the two groups(p=0.042). The total length of delivery time in the group which had the SP6 acupressure was shorter than SP6 touch group (p=0.036). Conclusion: These findings showed that SP6 acupressure was effective related to labor pain, length of time for delivery. SP6 acupressure during labor could be applied as an effective nursing treatment.

According to the fast-paced environment of information technology and improving customer services, the design activities of logistics systems improve customer centric services and delivery performance implementing e-logistics system. The fundamental design issues that arise in the delivery system planning are optimizing the system with minimum cost and maximum throughput and service level. This study is concerned with the integrated model development of delivery system with customer responsive service level for DCM, Demand Chain Management. We used a two-step approach for this study. First, we formulated the supply. center facility planning using stochastic set-covering problem and assigned the customers to the supply center using clustering algorithm. Second, we developed vehicle delivery planning for a supply center based on GIS, GIS-VRP. Also we developed a GUI-type computer program for proposed method for supply center problem using GIS and Geo-DataBase of Busan area. The computational results showed that the proposed method was very effective on a set of test problems.

In this paper we study the delivery policy of internet bookstores and recommend the improved policy to increase customer satisfaction and sales revenue. We classify customers into two, the price-sensitive and the delivery time-sensitive, and develop a new shipping method, the unhurried shipping, for the price-sensitive who are reluctant to pay shipping fee for the small purchase but willing to wait extra time for the ordered goods. The customers could get discount on shipping fee by the unhurried shipping but have to accept the longer delivery lead-time. We investigate the possible ways to reduce costs with the prolonged delivery time and show that some costs regarding shipmentand inventory could be saved in order to make up for additional shipping costs for the price-sensitive.
