  • Through the pandemic, the topography of dining culture is rapidly changing due to the advancement of the food delivery market. Competition in the domestic market is intensifying as Coupang Eats recently surpassed Yogiyo and jumped to second place, and Baedal Minjok(Baemin), the industry's No. 1 company, is also preparing to introduce a subscription system. While the growth of the delivery market is slowing, the use of takeout and pick-up services is increasing due to rising delivery costs and food prices. From Generation Z's perspective, the main factors influencing the active use of app services were identified through prior research as usability and convenience, cost sensitivity, and hedonic motivation. While, they are leading the trend of minimizing spending through 'stepping stone consumption' and delivery pot process instead of choosing a subscription system. Accordingly, we aim to provide customers with a better experience and help strengthen competitiveness by proposing ways to improve and revitalize new delivery apps that reflect the characteristics of Gen.Z. As a result of the expert Delphi survey, we will receive impact evaluation scores in the following order: direct view of accumulated discounts, addition of family benefits, coupon reinforcement, SNS promotion, pick-up walk, in-store promotion, and discount rate display, and review their application to practice. It presents academic and policy implications regarding the food tech market.

  • The author studied the mental status of 497 patients admitted in non-psychiatric wards and 42 patients diagnosed as mental disorders by DSM-III-R criteria and admitted in three general hospitals located in Pusan city, using NADS and PSCS. The assessment were obtained from October, 1991 to March, 1992 and the results as follows: The mean ${\pm}$ SD of Anxiety-Depression scores were $34.4{\pm}10.4$ in non-psychiatric patients and $50.0{\pm}18.3$ in psychiatric patients. The psychiatric group had significantly higher scores than non-psychiatric group. The mean ${\pm}$ SD of Psychosis scores were $3.9{\pm}4.4$ in non-psychiatric patients and $20.3{\pm}9.8$ in psychiatric patients. The psychiatric group had significantly higher scores than non-psychiatric group. In the psychosocial factors, dissatisfaction in family atmosphere and acquaintanceship with parellts(P<0.001, relatively), pessimistic in future, present and past self-images(P<0.001, relatively), and yes in previous psychiatric treatment of admission(P<0.01, relatively) had common significant relationships to Anxiety-Depression and Psychosis scores. There were correlationships between NADS scores and PSCS scores(${\gamma}$ = 0.74), past and present self-images(${\gamma}$ = 0.45), present and future self images(${\gamma}$ = 0.45), past and future self-images(${\gamma}$ = 0.34) and family atmosphere and acquaintanceship with parents(${\gamma}$ = 0.49). The regression analysis revealed that present self-image, acquaintanceship with parents, future self-image, past self-image, and family atmosphere, in order of significance were to be descriptive or predicable variances for Anxiety-Depression status. The discriminant analysis according to Anxiety-Depression scores showed that the cases of incorrect classification were 22 for non-psychiatric patient group and 2 for psychiatric patient group.

  • Objective : The purpose of this study was to identify the effect of Interactive Metronome (IM) training on postural control and hand writing performance of children with Attention Deficit Hyperactivity Disorder (ADHD). Methods : Participant was a third grade elementary school student diagnosed with ADHD. ABA design was used and a total of 30 sessions were held for 3 sessions every week for a total of 10 weeks. In the intervention period, IM training was conducted for 40~50 minutes before intervention for writing, and the writing task was carried out. We evaluated the handwriting legibility and speed. Before baseline A and within a month after A' phase, Clinical Observation of Motor and Postural Skills (COMPS) was evaluated to examine the changes in postural control of the student. Results : After the IM intervention, the postural control of the student improved in the score of slow movement, finger-nose touching, and asymmetrical tonic neck reflex. The handwriting legibility and speed has also tended to increase during the intervention period, but it has not significantly changed. Conclusion : This study could be used as an evidence that the IM training aimed at postural control and handwriting ability could enhance the ability to improve postural control and thereby provide fundamental knowledge for future studies.

  • Purpose: A large number of attributes with mixed levels are often considered in the conjoint analysis. The respondents may have difficulty with scoring their preferences accurately because of many attribute items involved in each survey question. We research on the technique for reducing the number of attribute items. Methods: In order to reduce the number of attribute items in a survey question, we make a new attribute by merging two original attributes. A 'No question' option is also included as a new level in a merged attribute. Results: We propose BIB $6^4$ design in the case where we have four attributes with 2 levels and 3 levels, respectively and then analyze all the respondents survey data generated by the repeated simulation study in order to compare various model selection methods. Conclusion: How to reduce the number of attribute items is proposed and how to design and analyze the survey data are illustrated.

  • This study examined the applicability of robust decision making (RDM) over standard decision making (SDM) by comparing each result of water supply planning under climate change uncertainties for a Korean dam case. RDM determines the rank of alternatives using the regret criterion which derives less fluctuating alternatives under the risk level regardless of scenarios. RDM and SDM methods were applied to assess hypothetic scenarios of water supply planning for the Andong dam and Imha dam basins. After generating various climate change scenarios and six assumed alternatives, the rank of alternatives was estimated by RDM and SDM respectively. As a result, the average difference in the rank of alternatives between RDM and SDM methods is 0.33~1.33 even though the same scenarios and alternatives were used to be ranked by both of RDM and SDM. This study has significance in terms of an attempt to assess a new approach to decision making for responding to climate change uncertainties in Korea. The effectiveness of RDM under more various conditions should be verified in the future.

  • Lean Construction recommends implementing site production management by measuring the reliability of daily production tasks, collecting the causes for failure of incomplete tasks, and identifying problems in the existing process based on the collected data. Although many research projects have been performed to introduce Lean Construction in Korea, there are not many cases in which day-to-day site production operations has been stringently evaluated based on such methods. This paper introduces three cases in which such techniques were implemented on a residential, civil infrastructure and plant project. On each project, process maps were created with the superintendents and daily production meetings were held for two weeks. Consequently, the average PPC for the three projects was 79% for PPC and 16% for PAT. In addition, the majority of the failures were due to 'Directive/Plan' and 'Prerequisites.' The results show that project stakeholders (owners, contractors, etc.) lack the ability to plan ahead and keep to their plans, and also lack the capability to synchronize workflow between themselves. The results also reveal that project participants need to be more proactive in solving process problems on site and also need to be better educated in Lean concepts and methodologies.

  • Objective : This study aimed to acquire activities of daily living (ADL) skills through activity analysis and forward chaining in children with developmental disabilities. Methods : In this study, the performance of children with developmental disabilities was guided stepwise using a changing criterion design. The intervention was conducted in forward chaining after the therapist analyzed the activities of three tasks (shoes, shorts, and short-sleeved T-shirts) set as the Canadian Occupational Performance Measure (COPM). The performance rate at each stage of the three tasks was used as an independent variable, and COPM performance and satisfaction scores before and after the intervention were set as dependent variables. Results : The task performance rates of children wearing shoes, shorts, and short-sleeved T-shirts improved over time. Even at home, the scores for performance and satisfaction of all three tasks increased. Conclusion : Hopefully, activity analysis and behavioral chaining methods will be used not only for ADL but also for various tasks in children with developmental disabilities who have difficulty acquiring tasks.
