  • This study intends to present a direction for the better reforming of fishers'onboard living conditions and proposals for preparing for ratification of the Work in Fishing Convention by means of making a comparison between standards on recent national fishing vessel accommodation facilities and standards on the Work in Fishing Convention and Its Recommendation, 2007, ILO. For the most part of standards on national fishing vessel accommodation facilities are somewhat insufficient to satisfy the provisions in Annex III of the Convention. Considering by items on fishing vessel accommodation facilities, the standards on insect protector, noise and vibration, heating and air conditioning, lighting, persons per sleeping room, recreational facility are not provided in national law. Headroom, separation of accommodation, sleeping room floor area, mattress size, mess room, galley and food storage are partially sufficient for the Convention. In case of sanitary facilities, national standards are not sufficient for the Convention. The other side, facilities related safety of ship and crew such as emergency escape etc., are fully sufficient for the Convention. These insufficiencies caused by different types of fishing vessel depend on originality of fishing method and practices. In the comparison between equivalent tonnage about vessel's length on convention and calculated tonnage of national existing fishing vessel, the difference are 226tons about length 24m and 501tons about length 45m. For that reason, headroom, persons per sleeping room, cabin of sicker and injured, sanitary facilities may decide to use gross tonnage in place of length (L) and the alleviating measure basis of convention. But in case of standards on sanitary facilities which are unsufficient for the Convention, specially in coastal fishing vessel length basis should be adopted with alleviating basis for less than length 24m.

  • The energy makes the basic element which improves the quality of life with motive power of industry and life. However, using the fossil fuel resources was restricted through it's abuse and exhaustion, and that cause a global warming resultingly. According to the reason, the world increased the interest that are stability and use of new and renewable energy which is clean energy with environment. Therefore, the property data of new and renewable is needed for developing and supplying the energy. In other words, the data of new and renewable energy becomes the standards for supply and evaluation of new and renewable energy with development of industry and technology. Also, the necessity came to the fore as the reference and standards of new and renewable energy data. Therefore, in this study, we evaluate and collect the solar radiation data as the new and renewable data and process the collected data through the standards for valuation. We evaluate uncertainty with standards which are NREL, WMO, and GUM. Whereby the data becomes reference standards data and gains the credibility. For the reliability data, we correct the measuring instrument with correction period. Using the DQMS and SERI QC, we efficiently manage and evaluate the solar radiation data. As a result, we evaluate uncertainty as 1,120 case about 16 area. we achieve credibility of data from evaluated solar radiation data and provide an accurate information to user. The annual average of horizontal radiation presents between 1,484 and 4,577, then the uncertainty evaluates from 163 to 453. The error of uncertainty presents smaller than the measurement values. So, we judge a credibility of data by expression of reliability quantitatively. In additional, the reference standards data which is possible to approach anywhere will be used for the supporting related industry and policy making.

  • The Korea Institute of Curriculum and Evaluation(KICE) has carried out the research on the development of the standards on teaching evaluation between 2004 and 2006, and particularly on the 'mathematics' teaching evaluation in 2006. The purpose of development of mathematics teaching evaluation standards is to improve not only mathematics teachers' professionalism but also their own teaching methods or strategies. The standards on mathematics teaching evaluation were developed based on the standards on general (not individual subject) teaching evaluation. They were revised and modified by analyzing the results of the interviews and survey with teachers about the adaptability of the standards in school. The standards were classified into four major areas of knowledge, planning, practice, and professionalism. Each area of these four were categorized into 6 smaller divisions and 36 elements. In addition, it was presented that brief descriptions on each teaching evaluation standards(element), guideline for evaluation methods, evaluator's observation index, and performance level with explanation for the standard achievement in four stages.

  • In this study, we present an analysis framework based on the 2015 revised curriculum to analyze how mathematical contents and achievement standards for domains of numbers and computations have changed in the curriculum of elementary mathematics in Korea. Based on this, we classified the achievement standards by type and investigated their characteristics. The achievement standards for numbers and computations can be divided into the successive, the extinctive, and the additive achievement standards depending on their characteristics. The successive achievement standards are the ones that have consistently existed without being removed from the 1-st curriculum to the latest revision in 2015. The extinctive achievement standards are the ones that have been removed at some point during the revisions of nine times and do not remain in the current revision in 2015. The characteristics of the extinctive achievement standards were analyzed to be different before and after the 4-th curriculum. The additive achievement standards refer to the ones that have been newly added to the curriculum or that have been removed at a certain moment but added back in later and thus exist in the current revision in 2015. The characteristics of each type according to the changes of the achievement standards can be thought to be the results that the revision for the mathematics curriculum in Korea has been faithfully conducted. Based on the results of this study, we suggest some implications for organizing the achievement standards in the future curricular development.

  • As local flash flood exceeding planned capacity occurs frequently, localized preparedness and response to flood inundation are increasingly important. Using XP-SWMM model and GIS techniques, this study analyzes inundation areas by local flash flood and develops rainfall standards for evacuation with the case of Sadang-Cheon area, a local stream and its nearby highly populated watershed in the southern part of metropolitan Seoul, Flood inundation areas overflowed from drainage systems are analyzed and mapped by amount of rainfall that is derived from reference levels of stream flow. Rainfall standards for evacuation are comprised of 'watch' (40mm/hr) in preparing for near-future inundation and 'evacuation' (65mm/hr) in responding to realized inundation. The methods suggested by this case study may be applied to other urban areas for sound flood prevention policy measures and thus risk minimization.

  • This study is to set up a model of minimum and optimum standards for college and university library building areas in Korea. The results of this study are summarized as follows: 1. minimum standards(proposal) At first, Areas needed by factors of space component are as follows: User space --- 0.45 $m^{2}$ per student. Collection space --- 0.0107 $m^{2}$ per volume Staff space --- 10.1 $m^{2}$ per person Space attached to user, collection and staff space --- 5% of the sum of user, collection and staff areas(0.041 $m^{2}$ per student). Nonassignable space --- 25% of the sum of user, collection and staff areas (0.21 $m^{2}$ per student). Next, the formula to calculate the total area of the college and university library building is as follows: N = 0.45T $m^{2}$(a) + 0.0107V $m^{2}$(b) + 10.1S $m^{2}$(c) + 0.05(a+b+c) $m^{2}$, NS = 0.25N $m^{2}$. 2. Optimum standards(proposal) At first, Areas needed by factors of space component are as follows: User spae --- 0.64 $m^{2}$) per student. Collection space --- 0.01 $m^{2}$ per volume Staff space --- 9.7 $m^{2}$ per person Space attached to user, collection and staff space --- 5% of the sum of user, collection and staff areas(0.073 $m^{2}$ per student). Nonassignable space --- 25% of the sum of user, collection and staff areas(0.38 $m^{2}$ per student). Next, the formula to calculate the total area of the college and university library building is as follows: N = 0.64T $m^{2}$(a) + 0.01V $m^{2}$(b) + 9.7S $m^{2}$(c) + 0.05(a+b+c) $m^{2}$, NS = 0.25N $m^{2}$.

  • This study was conducted to investigate food purchasing management and the perception of school dietitians regarding food quality standards in the Chonbuk area of Korea. Self-administered questionnaires were collected from a total 205 dietitians and then evaluated using SPSS v. 11.5. The results are summarized as follows. Among the 205 school foodservice systems evaluated, 63.4% used a conventional system, while 36.6% were operated in a commissary manner. In addition, 64.9% of the schools had a menu cycle of 1 week (p<0.05) and 72.2% of the dietitians were responsible for the entire purchasing process (p<0.05). Moreover, a dietitian, school staff, foodservice staff, and parents participated in receiving and inspection of the food at 95.6% of the schools. Additionally, wholesalers and informal purchasing were preferred for purchasing food supplies. Moreover, 33.3% of dietitians in the commissary systems responded that they made Kimchi themselves instead of purchasing it (p<0.01). When the dietician's perception of food quality was evaluated, the average score was 3.33 based on a 5-point scale, although the scores differed significantly between dieticians working in conventional systems and those working in commissary systems (p<0.05). The scores for the quality standards related to the GMO agricultural and pesticide residues were the lowest. These findings indicate that it is necessary to develop standardized food quality and purchasing criteria and to provide education regarding these criteria to school dietitians to enable them to improve their knowledge regarding food quality standards and to implement effective purchasing programs.

  • Currently, design speed selection is chosen by highway function, terrain type and area type. But some standards in classifing highway function let designer decide design speed in an arbitrary manner and too rough a highway function classification system leads to a road function which can not reflect road design, and some ambiguity of terrain type leads to a road which can not reflect land use pattern. Highway design based on traffic volume level without considering area type can result high construction cost. This research paper provides new highway design standards which are based on the refinement of highway design speed selection procedure. The new design speed is summarized to be determined by a more detailed highway function, terrain type, and area type that were made considering South Korean characteristics. The new highway function is established by adopting highway function reclassification and design volumes and rural town center reclassification and new design standards for terrain type selection are developed in this research by analyzing South Korean GIS Data Base obtained over the national government offices.

  • The citizens seek to maximize convenience, pleasantness and safety when they use urban facilities. However, existing practices of urban neighborhood parks have applied not qualitative standards such as adequacy, efficiency, accessibility, equity, or socioeconomic issues but very limited quantitative standards such as area per person. Therefore it is not rare that citizens have lost their accessibility to near-by neighborhood parks. And park regulations based on the distance of lien are supposed to be uniformally accomplished regardless of the consideration about users or geographical special situations. Futhermore, it has been found that some urban neighborhood parks don't reach to the standards given by the regulations. This study tries to accomplished several purposes. The first purpose is to extract the boundary of real user-accessible zones derived from the city survey. Comparing with boundary of real user-accessible zones, the second one is to propose the most efficient measurement indices among many accessibility measurement index. Based upon the above arguments, the last one is to review the propriety of the access distances(e.g., semidiameter) of an urban neighborhood park in a law. The measurement indices of accessibility examined in this study are walking distance, walking time and walking difficulty. The comparison of visual discrimination, the comparison of area and the comparison of differences of maximum distance showed similar results. Each index can also be compared in the size of area and differences of maximum distance. Walking difficulty with the turning showed the best measurement values among the measurement indices. This indicates that walking difficulty with crossing and/or turning may be another important indices in measuring accessibility, while other existing studues have mainly dealt with walking time and distance as accessibility indices. The results of this study also supported that the existing regulations related to park allocation(e.g., access diameter) are close to the findings of this study.
