Purpose: This study attempted to develop clinical guidelines to help patients use hospice and palliative care (HPC) at an appropriate time after writing physician orders for life-sustaining treatment (POLST) by identifying the characteristics of HPC use of patients with terminal cancer. Methods: This retrospective study was conducted to understand the characteristics of HPC use of patients with terminal cancer through decision tree analysis. The participants were 394 terminal cancer patients who were hospitalized at a cancer-specialized hospital in Seoul, South Korea and wrote POLST from January 1, 2019 to March 31, 2021. Results: The predictive model for the characteristics of HPC use showed three main nodes (living together, pain control, and period to death after writing POLST). The decision tree analysis of HPC use by terminal cancer patients showed that the most likely group to use HPC use was terminal cancer patients who had a cohabitant, received pain control, and died 2 months or more after writing a POLST. The probability of HPC usage rate in this group was 87.5%. The next most likely group to use HPC had a cohabitant and received pain control; 64.8% of this group used HPC. Finally, 55.1% of participants who had a cohabitant used HPC, which was a significantly higher proportion than that of participants who did not have a cohabitant (1.7%). Conclusion: This study provides meaningful clinical evidence to help make decisions on HPC use more easily at an appropriate time.

This paper suggests a decision tree based approach for flexible job shop scheduling with multiple process plans. The problem is to determine the operation/machine pairs and the sequence of the jobs assigned to each machine. Two decision tree based scheduling mechanisms are developed for static and dynamic flexible job shops. In the static case, all jobs are given in advance and the decision tree is used to select a priority dispatching rule to process all the jobs. Also, in the dynamic case, the jobs arrive over time and the decision tree, updated regularly, is used to select a priority rule in real-time according to a rescheduling strategy. The two decision tree based mechanisms were applied to a flexible job shop case with reconfigurable manufacturing cells and a conventional job shop, and the results are reported for various system performance measures.

The test and evaluation(T&E) of weapon systems is a significant activity in the decision-making process of defense acquisition program, providing the data of trade-off analysis, risk reduction and readiness to advance to next phase of development for the decision-maker. Currently, the modeling and simulation(M&S) is being a critical method in the test and evaluation of weapon systems. Therefore in this paper we review the current status of the test and evaluation for the defense acquisition program in Korea, and suggest an application of M&S in the T&E of weapon systems.

This paper studies a method for making more efficient classification rules in the ID3 using the rough set theory. Decision tree technique of the ID3 always uses all the attributes in a table of examples for making a new decision tree, but rough set technique can in advance eleminate dispensable attributes. And the former generates only one type of classification rules, but the latter generates all the possibles types of them. The rules generated by the rough set technique are the simplist from as proved by the rough set theory. Therefore, ID3, applying the rough set technique, can reduct the size of the table of examples, generate the simplist form of the classification rules, and also implement an effectie classification system.

The purpose of this study was to analyze the school location and site planning direction for land use planning of public land development. And this research proposed the direction of small park in school. So this research present the implication on urban planning and design for architecture, park-school complex. This study perform the relationship analysis on location of school and park. The result follows as this : 1) land use planning : Location and space of park-school must be checked in advance. Schools and parks are placed together. The park is located south of the school. 2) school site planning : Small field for dynamic activity is needed in school. The character of small park in school is relationship of educational programs. 3) management : CCTV is installed at school. Bright lights are placed in school. This result will be used in decision-making-process of land use planning, public land development construction, urban design and city policy.

This paper is focused on the introduction of the types of models and explanation of the fundamental concepts and theory for development and use of the corporate planning and modeling system. Nowadays, a great deal of companies have been or experimenting with some form of a corporate planning and modeling system to support managerial and strategic decision making. From previous studies it was noted that most applications have tended to be financially based. This trend will probably continue. However, with the software and hardware currently available it is likely that companies will move more toward integrated models that link marketing, production, as will as financial areas. More emphasis will undoubtedly be placed on the use of econometric modeling, since this subelement of the overall planning and modeling process is closely tied to the market place and the economy. At any rate, wherever the development of corporate planning and modeling system is directed, clear understanding for the fundamental concepts and elements of the system is settled in advance in order to develope and use it.

Objectives: This study was conducted to promote the value of field practice courses by installing an efficient field practice program through understanding the relationship between career decision/ behavior and the pre-/post satisfaction of dental hygiene students in field practice. Methods: The subjects of the study were students in Gyeongnam and Busan majoring in dental hygiene, from which 218 questionnaires were obtained from 23 November 2015 to 30 July 2016. Results: In terms of career decision/ behavior, the post-satisfaction scores in ideas about their major, about whether it was helpful to selecting their speciality and positive impression of dental hygienists, interest and understanding in training course were significantly lower than the pre-satisfaction scores (p<0.05). Relationship between satisfaction in field training and career decision/ behavior following the field training, pre-/post-satisfaction on site-training content (r=0.371, p<0.01), pre-/post satisfaction in training instructions (r=0.267, p<0.01), and pre-/post-satisfaction in the training sites (r=0.436, p<0.01) were all proportionally correlated to the after-training career decision and behavior. Conclusions: It is necessary for training instructors to maintain close relationships with the students in field practice program courses. In advance, it is expected to promote students' satisfaction in field practice and serve as a starting point where students can build self-esteem as a future dental hygienist by positively influencing their career decisions and behaviors.

It has been recognized as an important issue to design optimally a firm's logistics network for minimizing logistics cost and maximizing customer service. It is, however, not easy to get an optimal solution by analyzing trade-off of cost factors, dynamic and interdependent characteristics in the logistics network decision making. Although there has been some developments in a system which helps decision making for logistics analysis, it is true that there is no system for enterprise-wise's on-site support and methodical logistics decision. Specially, E-biz process along with information technology has been made dramatic advance in a various industries, there has been much need for practical education closely resembles on-site work. The software developed by this study materializes efficient algorithm suggested by recent studies in key topics of logistics such as location and allocation problem, traveling salesman problem, and vehicle routing problem and transportation and distribution problem. It also supports executing a variety of experimental design and analysis in a way of the most user friendly based on Java. In the near future, we expect that it can be extended to integrated supply chain solution by adding decision making in production in addition to a decision in logistics.
