Recently many efforts on the development of automatic processing system for delivery sequency sorting have been performed in ETRI, which requires the use of postal 4-state bar code system to encode delivery points. This paper addresses the issue on the extension of read range and the improvement of image processing method. For the improvement of image processing procedure, applied information acquisition method through basic two thresholds onto the horizontal axial line of gray image based on reference information of 4-state bar code symbology. Symbol values are computed after creating two threshold values based on the obtained information through search of horizontal axial values. The implementation result of 4-state bar code reader are obtained the symbol values within 30~60 msec (58,000~116,000 mail item/hour)without noise removal or image rotation in spite of the incline $\pm 45^{\circ}$.

The critical link between consumer-based internet ordering and the delivery of the product to the consumer is a key success factor in online shopping. Market areas of online shopping company implies the range of space where products ordered from online shopping can be physically delivered to customers distributed over space with reasonable shipping cost and lead time through the physical distribution network. The average rate of growth in online shopping is 36% per year in Korea for the last 5 years. But there are no maps available that describe sales/delivery density of online shopping, few researches are focused on the short-term/long-term adaptation to demand increase by online shopping. In this paper (1) Maps of trade area are described indicating the sales/delivery density around the nation. (2) Empirical researches suggested that short-term adaptation to demand increase resulted in price reduction and service in enhancement of service quality in local transportation. But the long-term adaptation on the parts of parcel delivery industry are to be investigated in future researches.

Due to the global pandemic aftermath of the coronavirus, the importance of health care is being emphasized more socially. Due to the influence of these changes, domestic pharmaceutical companies have introduced regular drug delivery services, that is, drug and health functional food subscription services. Currently, this market is continuously growing. However, these regular services are causing new environmental problems in which the number of waste drugs increases due to the presence of unused drugs. Therefore, this study proposes a service that not only promotes health management through regular medication adherence to reduce the amount of pharmaceutical waste but also aims to improve awareness and practices regarding proper medication disposal. As a preliminary survey for service design, a preliminary survey was conducted on 51 adults to confirm their perception of drug use habits and waste drug collection. Based on the Honey Comb model, a guideline for service design was created, and a prototype was produced by specifying the service using the preliminary survey results and service design methodology. In order to verify the effectiveness of the prototype, a first user task survey was conducted to identify the problems of the prototype, and after improving this, a second usability test was conducted on 49 adults to confirm the versatility of the service. Usability verification was conducted using SPSS Mac version 29.0. For the evaluation results of the questionnaire, Spearmann Correlation Analysis was conducted to confirm the relationship between frequency analysis and evaluation items. This study presents specific solutions to the problem of waste drugs due to the spread of drug subscription services.

This study was carried out to investigate the factors of food service satisfaction of the elderly in Busan. The survey was conducted from September 1 to October 15, 2009 by questionnaires and data analyzed by SPSS program. Fifty point nine percent of the subjects lived alone and the source of living expenses of 70.5% of the subjects was subsidy from government. The most important reason for the elderly to participate in meal service was 'economic difficulty' and 'to meet friend'. The subjects had various chronic degenerative diseases, such as arthritis, hypertension, diabetes, osteoporosis and cardiac disease. Sixty-six point eight percent of the subjects needed diet therapy for their diseases, but 87.1% of them don't want to pay the extra fee. Thirty six point five percent of the subjects attained information about lunch program because it was 'close to home' but 20.7% was 'from public officials'. The reasons for the use of the meal service were 'economic difficulty' (40.0%), 'to meet friends' (22.6%), and 'bother to prepare meal' (16.50%). The services provided by welfare center were health care, physical exam and haircut. The score given by the subjects on the satisfaction of meal service was 3.84 on the 5-point maximum scale. Higher satisfaction on kindness of staff, satisfaction of social support and awareness of support resulted in higher satisfaction of food service. It would be effective to provide food service models that meet specific needs of the elderly according to social welfare service and social community activities.

This thesis investigated disabled students' actual status of applying for university libraries. This thesis investigated how many times the university disabled students utilized the libraries, if facilities, apparatuses, materials, and regular employees were operated properly, and if they were established actually on the target at thirty private university libraries located at Seoul and Gyeonggi regions in operation of specially screening the objective students for special education in 2008. The investigation found that the general operation level of university libraries for disabled students were less than "medium"(average 2.38). As for utilization ratio, the most university students responded that "they didn't utilize libraries so many times(60%)". As for the response ratio of university library facilities and services, the most university students responded, "very insufficient", 99 items(32.27%), and the least university students responded, "very excellent", 28 items(7.0%). On the other hand, as for the analysis of each field, building facilities, in all of the items, were established more than "medium"(average 3.26), but material preparation level(average 1.8 point), employee education for softly supporting disabled students, and library utilization education on the target at disabled students(average 1.87) were less than "insufficient". Especially, the field of service was "insufficient level"(average 2.48), and standard deviation was more than 1.4. Manpower stationing and material delivery services have the biggest standard deviation between universities. So, this investigation found that university libraries reformed access to facilities a lot, but that its level of fundamental policy for library, such as materials, manpower, and the education on utilization, were in insufficient level.

The purpose of this study was conducted with suggesting a clue to improve the perception of jobs for the elderly, and the final study subject was 110 people. As a research methods were student t-test, ⲭ²-test, one-way ANOVA(Scheffe). The result of the study are as follows. The perception and economic status of the young elderly(65-74 years old) were significantly higher. The perception of public jobs was significantly higher when married, religious, and monthly income was more than 4 million won. The perception of social service-type jobs was significantly higher when married and when there was a religion. The perception of private jobs was high when the monthly income was more than 4 million won (p<0.05). The preference for "parking order service" in the public sector, "support for elderly facilities" in the social service sector, and "fast food restaurant employees, kitchen, restaurant assistants, and food delivery service workers" in the private sector was the highest. In conclusion, there is a need for an education program to improve the perception of jobs for the elderly in order to raise the awareness of job policies for the elderly, which decrease with age. It is expected to be used as basic data for job creation and job creation that can be done according to the age of the elderly.

Some subway passengers may want to have their fresh vegetables purchased through internet at a service facility within the subway station of the Metropolitan Seoul subway system on the way to home, which raises further questions about which stations are chosen to locate service facilities and how many passengers can use the facilities. This problem is well known as the pickup problem, and it can be solved on a traffic network with traffic flows which should be identified from origin stations to destination stations. Since flows of the subway passengers can be found from the smart card transaction database of the Metropolitan Seoul smart card system, the pickup problem in the Metropolitan Seoul subway system is to select subway stations for the service facilities such that captured passenger flows are maximized. In this paper, we have formulated a model of the pickup problem on the Metropolitan Seoul subway system with subway passenger flows, and have proposed a fast heuristic algorithm to select pickup stations which can capture the most passenger flows in each step from an origin-destination matrix which represents the passenger flows. We have applied the heuristic algorithm to select the pickup stations from a large volume of traffic network, the Metropolitan Seoul subway system, with about 400 subway stations and five millions passenger transactions daily. We have obtained not only the experimental results in fast response time, but also displayed the top 10 pickup stations in a subway guide map. In addition, we have shown that the resulting solution is nearly optimal by a few more supplementary experiments.

Food environment has been going through significant changes with the introduction of Information and Communication Technology (ICT). This study was conducted to investigate the current development status of ICT related to food delivery service by analyzing the relevant registered patents according to consumer buying process. Patents registered between 2002 and 2016 were searched with 'food' and 'delivery' as main keywords through Korea Intellectual Property Rights Information Service (www.kipris.or.kr). The search resulted in 624 patents among which 219 patents were related to food delivery service; 108 patents based on ICT were selected and analyzed. The patents were examined by applicant and year. The patents were classified into the six steps of consumer buying process: 'need recognition', 'information search', 'evaluation', 'choice', 'purchase', and 'postpurchase evaluation'. Patents belonging to more than one step were coded to all the corresponding steps. The patents were registered mainly by domestic companies (50.9%) and individuals (35.2%), having shown dramatic increase of registration since 2012. Over 2/3 (67.6%) of the patents were related to the 'purchase' step. About 32% were associated with the 'information search' step. Approximately 18% of the patents were relevant to the 'evaluation' and 'choice' steps, respectively. The numbers of patents related to the 'postpurchase evaluation (13.9%)' and 'need recognition (12.0%)' steps were relatively low. The current ICTs related to food delivery service in Korea were largely associated with service providers' profit generation rather than consumers' benefit. There is still much room for technology development that could contribute to increasing consumers' benefit.

Purpose/Design The purpose of this study is summarized as follows. First, we want to derive the quality dimension of the delivery app services based on the experience of the users of the delivery app. Second, we would like to identify the continuous intention to use, taking into account the integrated nature of online and offline quality. Third, the online and offline quality factors of the delivery app services shall be checked in an exploratory manner to see how they affect perceived value, satisfaction, and continuous intention to use. In order to demonstrate the purpose of this study, a self-report survey was conducted in which respondents directly responded. A questionnaire of 295 people was identified as a valid sample and used for the final analysis. Findings The summary of the hypothesis test results is as follows. First, the system quality among the online characteristics does not have a significant impact on both perceived values and user satisfaction. Second, the hypothesis that information quality affects satisfaction and perceived value was adopted. Third, the service quality was shown to be a significant factor affecting perceived value and satisfaction. Fourth, the delivery quality among offline characteristics was found to have no significant effect on perceived value and satisfaction. Fifth, the hypothesis test of commodity quality showed that both perceived value and satisfaction had a significant impact. Sixth, satisfaction in the delivery app service showed a positive effect on the continuous intention to use.
