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 paper uses the modified gravity model of international trade to examine the impact of ODA on the export of Korea to 28 aid recipients. In this perspective, the study includes recipient's economic size, trade openness, population, donor's scale of aid and distance between them as key determinants of the export of Korea by using panel data over the period of 2005-2012. To do this task, important econometric methods are fulfilled to test the model adequately, such as panel unit root and panel co-integration test. In addition, the study incorporated the panel OLS, panel GLM and panel EGLS methods. The empirical analysis clearly showed that an increase in Korea's ODA promotes its own exports. The coefficients of recipients's per capita GDP, population and trade openness have a positive impact on Korea's export respectively, while distance between them has a negative impact. Regarding regional dummy variables, aid for the region of Africa and America have a negative impact on Korea's export. Overall, the main implication of this study is that even if it emphasized Korea's economic interests as determinants of ODA disbursements, but it also suggests that an improvement of recipient's economic development, income distribution and educational environment can be an important concern in the future.

The purpose of this study was to develop a cognitive-behavioral academic stress coping training for reduction of elementary school children's academic stress and improvement the ability to handle academically stressful situation with effective way, to examine its effects. For this, we assigned students of Y elementary school in Gyeongnam Province to two groups at random. From a group of 12 each, one group became the experimental group and the other the control group. And the program was applied twice a week to the experimental group who had totally six 40 minutes sessions of the research own making. Moreover, students evaluated the effects of the program via questionnaire regarding to academic stress and strategy for it. From 120 students of Y elementary school in Gyeongnam province for 3weeks, the study gathered data through the questionnaire for academic stressful situation to know this which students of elementary school often experience. From this, the results are reflected in the program. Also cognitive behavioral group counselling program for teenagers in crisis and existing programs used to adjust academic stress was redeveloped as available form for students in elementary school to compose the cognitive-behavioral Academic stress coping training. In short, the results of the study is as follows. In the study, first, It was showed that cognitive-behavioral academic stress coping training decreased stress which can be caused in situation causing academic stress with a school record, lesson, study and task. Second, The cognitive-behavioral academic stress coping training showed the effect to improve coping strategy for academic stress. In detail, a passive-aversive coping strategy and a helpful coping strategy of coping strategy was enhanced meaningfully but the effect getting to an active coping strategy was limited.

The purpose of the study was to analyze the home economics education experts' and teachers' perception of ways to align instruction with evaluation, based on the 2015 revised technology and home economics curriculum for the purpose of developing the independent living competencies, and to provide examples of alignment in practice. The analysis is based on the data from a Delphi study (10 experts) and a survey of technology and home economics teachers(n=422). The results of survey indicated that experts and teachers perceived the instruction-assessment alignment to be most appropriate for project learning-project assessment, followed by project learning-portfolio assessment, problem solving learning-portfolio assessment, and problem solving learning-project assessment, in order. Based on the survey results, a model of instruction-assessment alignment and a teaching-learing plan were presented, based on 'Development task of life cycle and Life plan' unit. This was considered to be a proper method of instructional alignment for the purpose of developing 'independent living competence' with project-learning/project-assessment. The model focuses on consistency between instruction and evaluation, unity in methods, and the availablility of feedbacks of assessment for the improvement of independent living competencies. In conclusion, this study contributes as foundational information for teaching and learning-assessment alignment. Diverse methods of instruction-evaluation alignment is expected for future research.

Environmental Enrichment (EE) alone is not capable of enhancing the fine digit and the forelimb functions. Therefore, we applied modified constraint-induced movement therapy (mCIMT) under the influence of EE to assess its effect on promoting improved forelimb sensorimotor functions. Focal ischemic brain injury was produced in Sprague-Dawley rats (60 rats, $250{\pm}50$ g) through middle cerebral artery occlusion (MCAO). Before MCAO induction, all rats were trained in modified limb placing tests and reaching tasks for 1 week. Then they were randomly divided into three groups: Group I: application of standard environment (SE) after MCAO induction (n=20), Group II: application of EE after MCAO induction (n=20), Group III: MCAO+EE, mCIMT and task-oriented training that was initiated at 10th day after MCAO induction (n=20). We also applied mCIMT (between 9 AM and 5 PM/daily) which included restraining the forelimb ipsilateral to the lesion using the 'Jones & Schallert' method. We assessed the change of modified limb placing, single pellet reaching test and the immunoreactivity of BDNF by immunohistochemistry (pre, 1st, 5th, 10th and 20th day). Group I showed no improved outcome, whereas group II and III significantly improved on the use of the forelimb and the immunoreactivity. The qualitative analysis of the skilled reaching test, of group III showed the greatest improvement in the fine digit and the forelimb function. These results suggest that EE combined with mCIMT is more functional in promoting enhanced fine digit and forelimb functional movements.

As the Fundamentals of Construction Business Act was revised in December 2004 and its implementing ordinances and enforcement regulations were adjusted in June 2005, the screening system of low price subcontracting has been an obligation to the public owners, having brought about arguments for and against since it enacted in 1983. The statutes for low price subcontracting have been reinforced from this year; for example, it underlines to submit to a project and builds an information network of subcontracting works. The system's original intention was that prevents shoddy and fraudulent constructions caused by low price subcontracting and precludes disturbances of fair trade by screening that whether it satisfies the conditions or not in advance. But, the criterion for the existing low price subcontracting has several issues having held up a true mirror to the real situation. It is arguable to discharge an important task with the primary purpose. This dissertation have researched the problem with a deposit of subcontract and the low price subcontracting basic rate are being used by the criteria for deciding whether it is a low price subcontracting or not, so showing the plan of reformation based on the findings, it wishes to contribute toward making the most of the system's essential intent.

JejuHaenyeo(women diver) culture has been designated as UNESCO Intangible Cultural Heritage of Humanity(ICH) in 2016. However, the number of new Haenyeo is decreasing due to the hardships and difficulties of Haenyeo job, and the aging factor of Haenyeo is threatening the cultural preservation and inheritance. The study aims to analyze JejuHaenyeo's awareness on self, community and UNESCO ICH designation. The study further aims to check any significant difference in Haenyeo's self-awareness per age group to conclude an effective strategy for permanence of Haenyeo culture. 228 JejuHaenyeo were interviewed at "The 10th JejuHaenyeo World Festival" around the Jeju Haenyeo Museum in Gujwa-eup, Jeju-si. The test result shows the difference per age group on awareness on self and UNESCO ICH designation status. The younger the generation of Haenyeo it gets, the awareness on self and UNESCO ICH designation status of Haenyeo gets lowerer. Without an immediate improvement to supplement JejuHaenyeo's awareness on self and UNESCO ICH designation status, preservation and inheritance of JejuHaenyeo culture may not be an easy task in the future.

The present study attempts to provide basic directions to respond to sea-level rise effectively based on the status of sea-level rise and its impact. The impact of the sea-level rise will be one of the most adverse component among climate change due to global warming. The basic approach to deal with sea level rise requires both mitigation and adaptation. Though the emission reduction can reduce a portion of sea level rise, the rising trend cannot be avoided due to the difficulty of the emission reduction and a strong inertia of the ocean. Therefore an effective corresponding direction has to focus on the development of appropriate adaptation strategies. Because sea level rise problem has scientific uncertainty, the corresponding system has to be designed to deal with the processes of information and awareness, planning and design, implementation, and monitoring and evaluation in continuous and long-term process. The future task to correspond effectively to the issue in Korea includes the improvement of scientific information, the development of adaptative measures, the enhancement of people awareness, the consensus of corresponding necessity, and formation of integrated corresponding system.
