The Last PlannerSystem (LPS) has been implemented on construction projects to increase work flow reliability, a precondition for project performance againstproductivity and progress targets. The LPS encompasses four tiers of planning processes:master scheduling, phase scheduling, lookahead planning, and commitment / weeklywork planning. This research highlights deficiencies in the current implementation of LPS including poor lookahead planning which results in poor linkage between weeklywork plans and the master schedule. This poor linkage undetermines the ability of theweekly work planning process to select for execution tasks that are critical to projectsuccess. As a result, percent plan complete (PPC) becomes a weak indicator of project progress. The purpose of this research is to improve lookahead planning (the bridgebetween weekly work planning and master scheduling), improve PPC, and improve theselection of tasks that are critical to project success by increasing the link betweenShould, Can, Will, and Did (components of the LPS), thereby rendering PPC a betterindicator of project progress. The research employs the case study research method to describe deficiencies inthe current implementation of the LPS and suggest guidelines for a better application ofLPS in general and lookahead planning in particular. It then introduces an analyticalsimulation model to analyze the lookahead planning process. This is done by examining the impact on PPC of increasing two lookahead planning performance metrics: tasksanticipated (TA) and tasks made ready (TMR). Finally, the research investigates theimportance of the lookahead planning functions: identification and removal ofconstraints, task breakdown, and operations design.The research findings confirm the positive impact of improving lookaheadplanning (i.e., TA and TMR) on PPC. It also recognizes the need to perform lookaheadplanning differently for three types of work involving different levels of uncertainty:stable work, medium uncertainty work, and highly emergent work.The research confirms the LPS rules for practice and specifically the need to planin greater detail as time gets closer to performing the work. It highlights the role of LPSas a production system that incorporates deliberate planning (predetermined andoptimized) and situated planning (flexible and adaptive). Finally, the research presents recommendations for production planningimprovements in three areas: process related, (suggesting guidelines for practice),technical, (highlighting issues with current software programs and advocating theinclusion of collaborative planning capability), and organizational improvements(suggesting transitional steps when applying the LPS).

The ship's chart system was changed from the use of paper chart to the ENC (Electronic Navigational Chart) using ECDIS (Electronic Chart Display and Information System). The introduction of ENC in ships is necessary for ship automation and for the digitalizing of data and integration of information, but unexpected various problems have occurred and are posing a great threat to safe navigation in the transitional period when the new system has been applied to the sea. In this paper, to assess whether ECDIS contributes to the safety of navigation for its intended purposes as new navigation equipment, a usability test of ECDIS was conducted on masters and crew who have used ECDIS on ocean-going vessels. The result was verified with a paired sample T-test, and it was significantly analyzed with the effectiveness of a simplified task; cost efficiency was decreased since ECDIS was used. By analyzing 'MSC.1/Circ.1503 ECDIS - Guidance for good practice', we found that the effects of the maintenance of ECDIS software, operating anomalies identified within ECDIS, differences between raster chart display system (RCDS) and ECDIS, and matters of identification were compounded by the overlapping information on the safety of ships. The anomalies were also grouped according to their characteristics, and we proposed suitable improvements accordingly. The reason for the reduction in efficiency in the usability test was that the problems with ECDIS were intended to be solved only with the careful use of navigational officers who did not have systematic solutions. To solve these problems, the maintenance of software, the improvement of ECDIS anomalies, the reliable ENC issuance including the global oceans, and S-mode development are a priority.
This study is to provide evidence-based recommendations for the most-effective treatments of benign prostatic hyperplasia based on patient preference or clinical need, and to meta-analyze the Korean literatures for the development of BPH treatment guidelines. For these analyses, extensive literature searches (208 articles), with priority given to the Korean Journal of Urology, were conducted from 1960 to August, 1996. Meta-analysis, like all statistical analysis, has two main functions: data summarization (qualitative meta-analysis) and smoothing o. pattern recognition (quantitative meta-analysis). As well, critical reviews and syntheses with the mean and 90-percent confidence intervals for the likelihood were used to evaluate empirical evidence and significant outcomes of the BPH treatment literatures (106 articles). For this task, the Methodologic Panel for BPH Guidelines was composed of multidisciplinary experts in the field. The results of the study were summarized as follows: For all that watchful waiting is an appropriate treatment strategy for the majority of patients with prostatism, we couldn't find the Korean literatures which carried this article. The literatures on alpha-1-adrenergic receptor blockers provide no evidence to suggest that any one alpha blocker is more effective than another. The finasteride reduces the size of the prostate, on average, and leads to a small yet perceptible reduction in sysptoms. Of all treatment options, prostate surgery with transurethral resection of the prostate (TURP), transurethral incision of the prostate (TUIP), and so on, offers the best chance for symptom improvement. However, surgery also has the highest rates of significant complications. Therefore, surgery need not always be a treatment of last resort. Balloon dilation of the prostatic urethra is clearly less effective than surgery in relieving symptoms, but it is associated with fewer complications. Emerging technologies for treating BPH include lasers, coils, stents, thermal therapy and hyperthermia. Established technologies will also be reanalyzed as results of new trials are reported. Although this study has some limitations due to lacking for good quality literatures, ' it provides a cornerstone for our medical research. It represents the most current scientific knowledge regarding the clinical epidemiology including treatment of BPH. It will be revised and updated as needed.
Happiness is no more than a pleasant mental state that we can feel everyday. How to seek happiness is the key subject of positive psychology, for which we also need a clear neural system so that our emotional life can be accomplished. This is an issue in people with neural problems (such as psychopathy or hypochondria) as they can not achieve such emotional clarity. In this sense neuroscience is thought of as a new approach that can replace the traditional rational insight which has been aimed at completing a virtual life. But there is also a limit: we can not reach a virtual life with only a confirmation of our transitive state. A practice of virtue which our moral ethos aims at, has been a problem of rational insight. Here is a gap between our emotional life and our rational insight in which an anguish of psychology results. So a task we should combine organically is band between neuroscientific fact and ethical practice; a new addition to psychology. But unfortunately psychology can not solve this problem by itself, for it is a meta-question arising beyond psychology. Thus an explication of this meta-question is, I believe, a new theory of moral philosophy; one that can only be explored using an interdisciplinary approach.
Church education in Korean churches is facing a very serious crisis. This crisis is a negative perception of the church as viewed by the present society. The negative perception of the church has led to children, adolescents, young adults, and even adults leaving the church. There have been countless studies on the problem of Christian education and its alternatives. However, those problems still remain a matter of church education. The alternatives do not become viable and remain a problem. To solve these problems, a paradigm shift is required, and in order to overcome the crisis of the church, it is necessary to study alternatives and its method factors and find application points. Today's church education is absolutely influenced by postmodernism and informationalization. However, church education is education for Christian identity that transmits Christian faith. This Christian education is facing challenges and crises against its religious and academic identity. Christian education has a responsibility to be aware of this reality and to present alternatives to overcome various crises facing church education. Therefore, it is the task of church education to establish standards so that we can live a life where the Bible becomes the standard. In other words, it is to give them biblical faith. Furthermore, it is necessary to point out and understand Christian faith in the Korean church, which has been evaluated as insufficient. In addition, establishing a Christian worldview and realizing the Kingdom of God that practice justice and love in society are tasks that can be accomplished efficiently through Christian education. Therefore, the Korean church should actively seek ways to support the practice of Christian education as well as church education in forming ideal Christians which is the goal of Christian education.

The aim of this study is to identify future-oriented tasks for Korean dental hygienists based on a literature review. A literature search is performed using 14 keywords related to tasks carried out by dental hygienists, and included articles published from 2000 to 2019 in the databases KISS, RISS, DBpia, NDSL, Papersearch, Pubmed, and Google Scholar. Six reviewers assessed the titles and abstracts of articles, and an article was selected if the study was considered to cover future-oriented tasks for Korean dental hygienists. Based on the results six local studies and two foreign studies were used for literature review and data extraction. In total, 38 tasks were classified as future-oriented tasks of dental hygienists according to the following criteria: 1) tasks that were specifically referred to as future-oriented tasks, and 2) tasks that could be classified as future-oriented tasks although no specific reference was made. Of these, the most frequently mentioned tasks were measuring periodontal pocket depth, dental hygiene assessment, providing dietary advice, infiltration anesthesia, and root planing. These were extracted from five of the eight studies, including both local and foreign studies. Dental hygiene planning, emergency, emergency management, and smoking cessation were the next most common tasks based on four studies. Even though some of these future-oriented tasks for Korean dental hygienists are included in the dentistry curriculum, and are currently performed as clinical practice for dental hygienists. Nonetheless, the reference to the legal scope is unclear. It is necessary to reconsider the scope of tasks of dental hygienists to reflect changes in domestic and foreign dental care delivery, thereby contributing to the oral health promotion of the public, where safety is guaranteed under legal protection.
Objectives The purpose of this study is to improve the accessibility of Korean medicine by standardizing managements, improving quality of medical services, and reducing medical costs in ankle sprain by develop clinical pathway (CP). Methods The development of CP in this study is based on clinical practice guideline (CPG) for ankle sprain, and aims to maximize the quality of treatment, such as reducing treatment time and medical costs, and increasing patient satisfaction through standardized pathway. The CP was revised after consultation and review by the advisory committee. The advisory committee is consisted of a stakeholder group applying the CP. Results In previous research studies, there were no Korean medicine CP studies on ankle sprain. Based on CPG for ankle sprain and analysis of medical records, 6 types of time task matrix type CP (for Korean medicine doctors, medical assistant, patients) and 4 types of algorithm type CP (for Korean medicine clinics, Korean medicine hospitals, and cooperative practicing hospitals, public medical centers) were derived as a result. Conclusions Ankle sprain CP is expected to not only increase patient satisfaction and maximize the quality of treatment, but also reduce the financial burden of health insurance by reducing medical costs.
Struggle refers to the process of overcoming various difficulties for a goal. The spirit of struggle is a positive attitude and reaction reflected in the process of struggle. Cultivating the spirit of struggle of college students is the call of the new era. In essence, the cultivation of the spirit of struggle is a process of learning, which is in line with Bandura's Observation Learning Theory(Bandura, 1977):Attention, Maintenance, Reproduction and Motivation. The cultivation of College Students' spirit of struggle in the new era is also a learning process of enriched experience. It is necessary to cultivate the spirit of struggle into the soul of college students and make it become a habit of students. Moreover, it is crucial to carry out adaptive transformation of Bandura's observation learning theory. By studying the mechanism of the spirit of struggle of college students, taking innovation and entrepreneurship education as a means, and aiming at cultivating the connotation of President Xi's thought on socialism with Chinese characteristics for a new era, this paper constructs the AIST model for cultivating the spirit of struggle of college students in the new era. This model includes online learning acceptance platform(Acceptance), classroom experience stimulation platform(Inspiration), iterative training solidified platform (Solidification), and competition practice transfer platform(Transfer). The purpose of this model is to provide a practical way for universities to fulfill the fundamental task of moral education and cultivate qualified socialist builders and successors. The number of students using the online learning acceptance platform ranked the first among that of the similar courses in China; The classroom experience stimulation platform and the iterative training solidified platform support each other, with an effective rate of 97%; The competition practice transfer platform has realized the continuous growth of the number of awards won in competitions for three years. The direction of future efforts is to establish the external mechanism of the spirit of struggle, to ensure the effectiveness of classroom experience and iterative training, to cultivate teachers with coaching skills, and to accurately measure the transformation point of external and endogenous motivation.

Consultant and owner play a very important role in the construction sector which is one of the main sectors in economic development. There are many stakeholders in a construction project including but not limited to: owner, consultant, contractor, subcontractor, and supplier. The consultant is the party who is to stay in close touch with the project owner, which both consultant and owner are considered as the main key stakeholders to make the project happen. It's not a simple task for a consultant to just implement the same style of management and control within various projects that are of a different background and character of owners. Thus, the adjusting plan management and control to the owner environment has been an essential technique to drive the project to success. The objective of this paper is to identify the significant management techniques for adjusting a plan of management and control to the owner environment in Thailand. The methodology is the identification throughout the analogous to abduction from literature review and our empirical observations of Future Engineering Consultants Co, Ltd. We have been in consultation for twenty-five years (25) in Thailand with 209 projects from both public and private owners. As a result, there are (1) Project management styles, (2) Personal style, (3) Owner expectation management, (4) Scope Management, (5) Time Management, (6) Cost Management, (7) Quality Management, and (8) Environmental Management. The input are: a clear defined goal, showing respect by giving good service, maintaining high quality, keeping in touch with owners, and resources. This would give the output of the project's success by meeting the owner's expectation and requirements.
