Recently, there has been much interest in the converged platform that enables the harmonized collection, integration, exchange, presentation and analysis of various kinds of marine information by using the ICT means. Regarding such the converged platform, S-100 standards including the international hydrographic data model are being announced and various studies have been published based on the S-100 standards. However, the existing studies have presented simple solutions for only given problems on the converged service of the maritime information. They could not propose the design concept of the converged platform which makes it possible to provide the standardized and integrated services among the geospatial data, the real-time maritime data, and the next ENC. Therefore, we propose design and implementation details of the converged service platform for the geospatial and the maritime data based on the S-100, WMS, WMTS, WPS, SOS standards. The proposed platform has advantages of supporting both the S-57 and the S-101, supporting the converged services of heterogeneous geospatial data and ENC data, supporting the real-time services of sensor data such as weather, AIS, and CCTV, and supporting the development of various kinds of maritime systems such as ECDIS, ECS, VTS based on the WebApp service. Finally, we proved the effectiveness of our proposed platform through the actual implementation of the converged service of geospatial data, S-101 data, and KWeather data.
Article 37 of the International Convention on Civil Aviation requires that rules should be adopted to keep in compliance with international standards and recommended practices established by ICAO. As SARPs are revised annually, each ICAO Member State needs to reflect the new content in its national aviation Acts in a timely manner. In recent years, data-driven international standards have been developed because of the important roles of aviation safety data and information-based legislation in accident prevention based on human factors. The Safety Management System and crew Fatigue Risk Management Systems were reviewed as examples of the result of data-driven rulemaking. The safety management system was adopted in 2013 with the introduction of Annex 19 and Chapter 5 of the relevant manual describes safety data collection and analysis systems. Through analysis of safety data and information, decision makers can make informed data-driven decisions. The Republic of Korea introduced Safety Management System in accordance with Article 58 of the Aviation Safety Act for all airlines, maintenance companies, and airport corporations. To support the SMS, both mandatory reporting and voluntary safety reporting systems need to be in place. Up until now, the standard of administrative penal dispensation for violations of the safety management system has been very weak. Various regulations have been developed and implemented in the United States and Europe for the proper legislation of the safety management system. In the wake of the crash of the Colgan aircraft, the US Aviation Safety Committee recommended the US Federal Aviation Administration to establish a system that can identify and manage pilot fatigue hazards. In 2010, a notice of proposed rulemaking was issued by the Federal Aviation Administration and in 2011, the final rule was passed. The legislation was applied to help differentiate risk based on flight according to factors such as the pilot's duty starting time, the availability of the auxiliary crew, and the class of the rest facility. Numerous amounts data and information were analyzed during the rulemaking process, and reflected in the resultant regulations. A cost-benefit analysis, based on the data of the previous 10 year period, was conducted before the final legislation was reached and it was concluded that the cost benefits are positive. The Republic of Korea also currently has a clause on aviation safety legislation related to crew fatigue risk, where an airline can choose either to conform to the traditional flight time limitation standard or fatigue risk management system. In the United States, specifically for the purpose of data-driven rulemaking, the Airline Rulemaking Committee was formed, and operates in this capacity. Considering the advantageous results of the ARC in the US, and the D4S in Europe, this is a system that should definitely be introduced in Korea as well. A cost-benefit analysis is necessary, and can serve to strengthen the resulting legislation. In order to improve the effectiveness of data-based legislation, it is necessary to have reinforcement of experts and through them prepare a more detailed checklist of relevant variables.
The aim of this study was to explore the grade 1-3 students' geometrical thinking level descriptors based on van Hiele level descriptors. The data were collected through collection of geometric curriculum materials such as indicators and learning standards in Basic Education Core Curriculum and mathematics textbook for grades 1-3. The findings were found that 1) Inconsistency between descriptors appeared on mathematics curriculum and Thai mathematics textbooks. 2) Using topics on textbooks as criterion for exploring 5 of 7 descriptors appeared on Thai mathematics textbook indicated geometrical thinking levels based on van Hiele's model merely level 0 (Visualization) across textbooks for grades 1-3.
In this paper, we explore about Korean early childhood mathematics education history. Actually, mathematics education history is mathematics education curriculum's history. Korean education curriculum has been influenced by the US and European prominent educators: Montessori, Piaget, Bruno, and Dewey, etc. We investigate how those philosophy and thoughts were adopted in Korean early childhood mathematics education curriculums from 1st to 2015 amended curriculum. Also, we can see that NCTM's content standards and Korean Nuri curriculum are the same in the basic concepts: number and operations, space and shapes, measurement, understanding of patterns and data collection.

This paper presents brief history and a state-of-the-art survey of Life Cycle Cost (LCC) analysis, in particular LCC analysis in the Urban Transit Vehicle, based on a internationl codes and standards related to LCC analysis. A main objective of the LCC analysis is to quantify the total cost of ownership of a product throughout its full life cycle, which includes research and development, construction, operation and maintenance, and disposal. The predicted LCC is useful information for decision making in purchasing a product, in optimizing design, in scheduling maintenance, or in planning overhaul. This paper presents a LCC procedure consisting of seven steps, which are "Problems definition", "Cost elements definition", "System modeling", "Data collection", "Cost profile development", "Evaluation", and "Verification". Sub-activities to be encompassed in the seven steps procedure are described.
This study is understanding characteristics and analyzing contributions of the odor causing compounds of complex-odor & major specified odor materials, and contribution analysis, caused pre-treatment facilities(input and storage) and post-treatment facilities(heating and drying). The target of this study is feeds-production-facilities, located in Seoul. The averaged complex-odor compounds on the boundary line is 21 times higher, and it is 15 times higher than emission standards. In cracking&collection(pre-treatment facilities), the concentration of compounds is 4,881 times, 2,080 times in drying, and 1,442 times in putting&storing facilities. Ammonia occupies the largest portion of the results of monitoring specified odor compounds in input&storage facilities, followed Acetaldehyde > Hydrogen sulfide > Methyl mercaptan. In cracking&collection, Ammonia also occupies most of odor compounds, followed Methyl mercaptan > Acetaldehyde > Dimethyl disulfide > Dimethyl sulfide > Hydrogen sulfide. Acetaldehyde > Methyl mercaptan in drying facilities. On the boundary line, however, the concentration of specified odor compounds stays below emission standards. The result of contribution analysis is that methyl mercaptan has the highest contribution in input & storage, as well as cracking&collection facilities, followed Acetaldehyde > Hydrogen sulfide > Dimethyl sulfide > Dimethyl disulfide. In the drying facilities, the contribution shows Methyl mercaptan > Acetaldehyde > i-Valeraldehyde and Butyraldehyde. Therefore, to decrease odor in foodwaste treatment facilities, proper prevention facilities need to be installed and operated, according to characteristics of individual odor compounds, based on monitored data.

Purpose: The purpose of this study was to determine the most appropriate shelf life for sterilized products according to their packaging material. Methods: Samples were prepared to target six nursing units in one general hospital in Seoul. After steam and E.O gas sterilization, sterilized product, samples were supplied to wards. Data collection was conducted for 3 months, after the expiration date of 3 months had passed for samples packaged with crepe paper and nonwoven wraps. For samples packaged with paper-plastic pouches, data collection conducted for 3 months when the expiration date of 9 months had passed. The sterilized products were collected and tested for microbial contamination. Identification of the storage environment was done as samples were collected. Results: This study confirmed that the storage environment met international standards such as CDC, except for temperature. For steam sterilized crepe paper packaging samples and steam and E.O gas sterilized for nonwoven packaging samples no contamination in all products was found for 3 months past the expiration date. However, in the E.O gas sterilized paper-plastic pouch packaging sterile samples, Gram-positive bacilli were detected in one sample from a surgical intensive care unit at 45 weeks and another sample from an operating room at 47 weeks. Furthermore, the results did not show any microorganisms for up to 52 weeks in all products. Conclusion: According to the results of this study, sterilized product packaging made with crepe paper and nonwoven wraps is better able an extended shelf life from 3 months to 6 months, reducing unnecessary costs.

Nursing standards determine the type and extent of services that are delivered to the patients and define quality care and communicate the institution's expectations of care. Thus, taking the standard of care and incorporating it into a welldefined indicator of excellent patient care becomes one of the first activities in setting up the nursing service's quality assurance process. The purpose of this study was to determine the impact of using a nursing care standards for the quality of nursing care in gastrectomy patients. The subjects were composed of fourty-two under going gastrectomy patients with stomach cancer in general surgery nursing care unit of K University Hospital in Pusan. The data was collected from January 3 to April 13,1996. The subjects were divided into a control group - those admitted from Jan.3 to Feb.12 and an experimental group those admitted from Feb.18 to April 13. The instruments used for this study were a nursing care standards in gastrectomy patients developed by the investigator and an evaluation tool for the quality of nursing care in abdominal surgery patients developed by Byoung-Sook Lee in 1995. The data was analized by means of chi-square test, t-test and Cronbach-alpha test with the SAS System. The result was as follows : The hypothesis, that scores of the quality of nursing care in the experimental group would be higher than that of the control group. was supported(t=-6.12, p=0.00). The detailed results of each standards of evaluation tool were as follows : The mean score of the experimental group was significantly higher than that of the control group in audit standard 1:'Collection of basic data of the patients', (t=-3.76, p=0.00). The mean score of the experimental group was significantly higher than that of the control group in audit standard 2 : 'Defining nursing diagnoses(or nursing problems)', (t= (-), p= (-) ). The mean score of the experimental group was significantly higher than that of the control group in audit standard 3:'Estabilishment of nursing care plan according to nursing diagnoses(or nursing problems)',(t= (-), p= (-) ). The mean score of the experimental group was significantly higher than that of the control group in audit stndard 4:'Implimentation of nursing care plan', (t=-2.38, p=0.01). The mean score of the experimental group was significantly higher than that of the control group in audit standard 8 : 'Increase of the knowledge of health related to surgery',(t=-2.40, p=0.01). No significant differences between the mean scores of the experimental group and that of the control group in audit standard 5 : 'Recover and maintain of the physical function', audit standard 6:'Prevention of the post-operative complication', audit standard 7 : 'Decrease of discomfort caused by operation', and audit standard 9 : 'Patient satisfaction in nursing care' were found. The standards of evaluation tool were devided into two dimension. One was process dimension which contains four standards(audit standard 1 to 4), the other was outcome dimension which contains five standards(audit standard 5 to 9). The mean score of the experimental group was significantly higher than that of the control group in process dimension (t=-12.30, p=0.00), but no significant difference between the mean scores of the experimental group and that of the control group in outcome dimension was found. From these results, it is concluded that using a nursing care standards in gastrectomy patients promotes quality of nursing care and nursing care standards of various fields are necessary for effective nursing care.

Archival organizations have been evolving to varying users' needs. The main functional focus of earlier archival organizations has inclined to collection and preservation of data, but their current interests expand to utilization of the data collected. Therefore, today's archival organizations endeavor to procure user-oriented archival information service. This study highlights the programs initiated in last two years by 'Service Innovation Team', a special task force of National Archives of Korea organized in 2005, and presents comparative analysis of those programs with respect to the existing archival systems of National Archives and Records Administration of USA and The National Archives in UK. Additionally, the study, while emphasizing the importance of enlarging and diversifying service programs as well as promoting public awareness over archive resources, introduces the service standards of advanced nations as benchmarks for future archival service policies of pertinent organizations.
