The present SOLAS Convention has maintained safety regulations in a largely prescriptive form and this has become overly prescriptive now. The prescriptive rules do not properly reflect technical advances and changing environments in the maritime sector in a timely manner. The purpose of this study is to provide preliminary research to lay a foundation for the development of a new regulatory framework based on safety performance which is not a prescriptive rule making bases. This study reviewed the concept and characteristics of a minimum requirement, the implications of safety regulations in terms of strategic, commercial and technical aspects, the compensative correlation between constructional requirements and operational measures, the concept of safety with regard to final stage confirmation of functions, expansion of implementers and objects of safety regulations, and the balance between safety and environmental protection requirements. Based on these research, 10 principles for the rule formulation process has been suggested such as consideration on the hardware requirements and software requirement, the multi-stage approval concept, new safety concerns for complex shipboard systems, considerations on the human element, regulatory impact assessments and measures to reduce administrative burdens.

The purpose of this study was to determine whether the results of KTAS(Korean Triage and Acuity Scale) triage classifier differ according to the occupations. We analyzed a total of 10,960,359 cases of data sent to the NEDIS from January 1st, 2016 to December 31th, 2017. The triage classifier were MD(Medical Doctor), R(Resident), INT(Intern), GP(General Practitioner), RN(Registered Nurses) and EMT(Emergency Medical Technician). The consistency between the initial triage and final triage results was the highest GP(98.9%) and the lowest INT(80.2%). The results of over-triage classification was the lowest by GP(0.6%) and the highest for INT(16.0%). Also, the results of under-triage classification was the lowest by MD, EMT(0.4%) and the highest for INT(3.8%). The results of KTAS triage classifier significantly differ from according to the occupations(p<0.001). Triage classification should not differ from according to occupations and skill. It is necessary to strengthen the classifier's capacity for accurate triage classifications.

Although infrastructure cost comprises the great proportion of residential development cost, all of it tends to be borne by land developers which develop large area. This brings about free-riding by adjacent small development or built-up area, followed by the equity problem in terms of infrastructure development cost sharing and the privatization of development gain. This study aims to establish the method to analyze free-riding on the transportation infrastructure(roads) and investigate empirically how much the free-riding occurs. It sets several development scenarios to calculate the part generated by Bucheon Sangdong district, the case area of this study, of all the traffic flow on the roads. The Network analysis is used to estimate the proportion, by development scenarios, of traffic flow, travel time, and travel cost. As a result, the developer of Bucheon Sangdong district is responsible for 83% of the construction cost of selected roads. The methodology and empirical result of this study would contribute to determine who are liable for the infrastructure facilitation and to estimate how much of the cost the obligators have to share.

Recently, the integrated management of the quantity and quality of water was been derived by the Ministry of Environment in Korea. This reconstruction in the national government organization can be recognized as the major politic measure. For this IWRM (Integrated Water Resources Management), it is necessary to be able to fairly distribute, operate and manage water resources in a situation where related techniques are needed to fully support, such as measuring exactly the demand and supply of water resources. The reason why IWRM is difficult, despite the development of related technologies, is because the management entities are highly diverse and their interests are much complicated. Thus, this study is tried to suggest specific improvement for current policies by benchmarking the KPX (Korea Power Exchange). In the field of water management as similar to the electric industry, there is an essential need for a working-level organization that can manage, control, monitor, and regulate water resources with practical and plenipotentiary control like the non-profit organization, KPX. Such time has come for decisive policy changes through benchmarking the structure, system, productivity, and challenges of the electricity industry in the water policy.

This study aims to explore an evolutionary path of the IT service industry in Fairfax County using the Cluster Adaptive Cycle model in economic geography. The analysis is based on detailed historical and industrial information obtained through a variety of data sources including local archival materials, economic census, and interviews. This study also performs a shift-share analysis during the period of 1990 to 2011. Using the adaptive cycle model, the local IT service industry is indicated by a trajectory of constant cluster mutation. The evolution of the local IT service industry has been closely related to federal government policy due to the regional specificity of the National Capital Region and the proximity of the Department of Defense. Although the economic downturn of the late 2000s, the local IT service industry has been notable resilience and adapted to a changing market and technological environment. This constant mutation of the local industry is resulted from not only high resilience which is based on the large government procurement market, the reinforcement of adaptive capacity of the local firms and the network of economic agents such as firm and supporting institutions, but also high flexibility of the knowledge-based service industry to a changing business environment.

This survey was performed as a pilot of comprehensive survey of 18-month old infants which is an important period in pediatric dentistry. Through the oral examination of 154 infants of 18-month age, labored at Pusan National University Hospital and Ilsin Christian Hospital, and direct interview with their first caregivers (mother in most cases), we investigated into the state of their weaning and feeding, between-meal snacks, oral hygiene care, tooth eruption and dental caries and obtained the results as follows : 1. 73% of the infants had not yet weaned, and 82% of which were being milked during or before sleep without oral hygine care. 2. Snacks were taken in order of fruits, biscuits, cheese, bread and candies, and beverages in order of water, fermented milks, milk, sugared juice, fresh fruit juice. 61% of the infants ate snacks irregularly. 3. The toothbrush for infants was the most popular way of oral hygiene care. The mean age of initiation of tooth brushing was 13.8 months and the mean frequency was 1.6 times a day. 4. The incisors in all infants, the 1st molars in 86%, and canines in 66% were erupted. The average number of erupted teeth was 14.1. 5. The caries prevalence rate was 27.3% and 73% of total caries was observed in maxillary deciduous incisors. dmft index was 0.97. Through these results, it was concluded that a systematic education about weaning time, mode of snacking and the way of oral hygine care is required for the parents.

The goal of this study was to investigate the differences in the effect of feedback from different providers on elementary school students' science achievement and to examine the responses of the students regarding the feedback. Three 6th grade classes were chosen to be assigned as experimental group 1, experimental group 2, and control group, respectively. In experimental group 1, the teacher provided feedback with students concerning the formative evaluations which were conducted periodically. Experimental group 2 was the one in which students were organized into small groups to compose and exchange feedback with one another. No feedback was of offered to students in the control group. The results of the science achievement test indicated ,that the provision of feedback by the teacher resulted in more gains in student academic achievement. The interviews with students revealed that the learners made positive responses to the feedback provided by the teacher while they showed negative attitudes toward the feedback exchange among students. There were also differences in student responses to feedback between high and low achievers in science. Implications for science lessons and science education research were presented and discussed.

KCTA(Korea Container Terminal Authority) is going to introduce automated operating system in the port of Gwangyang container terminal to enhance the efficiency. Prior to developing the container terminal, defining the objective of container terminal operation is essential. This research used AHP technique to define the operation objective of automated container terminal objectively, and the questionnaire to collect the opinions of future customer, operator and research institution. The objectives mix of the automated container terminal are composed of the minimization of initial investments, the minimization of operational expenses, the performance of automation system, the raising of operation efficiency and productivity and the improvement of customer service. The result of the analysis revealed that most important factor among objectives mix was “the minimization of operation expense”. Especially, the user group preferred to select the factor of “the improvement of customer service”as objective rather than select other objectives. The result of this research will suggest some guidelines for deciding the level of investment of terminal construction. information system, automation equipment, terminal worker and etc., which are to be considered in terminal development and the system development hereafter.

The purpose of this study was to develop a scenario suited for our clinical situations and evaluate the application possibility by evaluating students' problem solving ability and learning satisfaction in simulation learning. This study consisted of contents which could be applied for varied situations such as complications and symptoms related to liver cirrhosis, looking into hyperkalemia symptoms of patients with liver cirrhosis in emergency unit. The stage of developing scenario was organized in the order of setting simulation learning objectives and situations of scenario, making algorithm, writing checklists of clinical performance appraisal, and debriefing. The scenario was constructed with monitor setting(actions), patient/mannequin(actions), expected interventions(events), and cues in chronological order, according to the scenario progression outline of Jeffries (2007). The scenario was used in 2011, consisting of 4-5 people per group of 53 senior nursing students who registered for 'clinical performance appraisal' course. The problem solving ability improved from a score of 4.05 before simulation learning to a score of 4.30 after simulation learning (t=-3.97, p<.001). The score for learning satisfaction after the simulation learning was high (4.09/5). Considering that simulation learning encouraged students to be the main body of class, this learning method can be the effective way of nursing education.

This paper deals with the novel concept of neo-endogenous rural development which has been applied to explain the contemporary features of the European rural development. The notion of neo-endogenous rural development has been emerged in Europe because the pervious dichotomous concepts of exogenous and endogenous development are no longer useful for explaining the relationship between the local actors and the central or regional administrative organisations. The concept argues that the changing situation of rural regions at the initial stages of endogenous development could only be identified by the concept of neo-endogenous perspectives. Therefore, it tries to apply the concept for the Korean rural development policy which is called Regional Agricultural Cluster scheme. Explaining the development processes and the problems of the farmers group which carried out the project in a local level, this paper argues that the severe conflict between the farmers group and the City Office may be a typical incident of the neo-endogenous development. It expresses the power relations between the local groups and the political managing authority. With the case of the Prundle, it concludes that the neo-endogenous development is the essential stage for all the endogenous development to go through as an transitional one.
