This research was conducted to improve the image of female emergency workers in a fire service organization by studying the perception trends of the increasing number of female paramedics. This human resource can be utilized more effectively by using the study results as baseline data. We conducted a survey from May 1 to June 30, 2013. The survey was analyzed using Q methodology and the program QUANL. For the Q sample, 31 emergency rescue paramedic students who had experienced ambulance field education were selected. As a result, four types of female paramedics were found; "superwoman," "hero" (who pushes against limits of stamina), "delicate guardian angel," and "skillful desk worker." The explanation powers were as follows: type I: 42.2%; type II: 4.8%; type III: 4%; and type IV: 3.6%. The sum of the figures explained 54.7% of the total variables. Generally, the students recognized female paramedics as professionals, but physical strength, baby care, and caring were considered as burdens. This requires changes in the organization's perception of female paramedics and an institutional strategy.

This study was conducted to discuss educational implications by analyzing the types of mathematical thinking that appeared in challenge math in 5th and 6th grade math teacher's guidebooks. To this end, mathematical thinking types that can be evaluated and nurtured based on teaching and learning contents were organized, a framework for analyzing mathematical thinking was devised, and mathematical thinking appearing in Challenge Math in the 5th and 6th grade math teachers' guidebooks was analyzed. As a result of the analysis, first, 'challenge mathematics' in the 5th and 6th grades of elementary school in Korea consists of various problems that can guide various mathematical thinking at the stage of planning and implementation. However, it is feared that only the intended mathematical thinking will be expressed due to detailed auxiliary questions, and it is unclear whether it can cause mathematical thinking on its own. Second, it is difficult to induce various mathematical thinking at that stage because the questionnaire of the teacher's guidebooks understanding stage and the questionnaire of the reflection stage are presented very typically. Third, the teacher's guidebooks lacks an explicit explanation of mathematical thinking, and it will be necessary to supplement the explicit explanation of mathematical thinking in the future teacher's guidebooks.

In the shipping industry, it is essential to engage in the preemptive prediction of freight rate volatility through market monitoring. Considering that freight rates have already started to fall, the loss of shipping companies will soon be uncontrollable. Therefore, in this study, factors affecting the freight rates of bulk carriers, which have relatively large freight rate volatility as compared to container freight rates, were quantified and analyzed. In doing so, we intended to contribute to future shipping market monitoring. We performed an analysis using a vector error correction model and estimated the influence of six independent variables on the charter rates of bulk carriers by Handy Size, Supramax, Panamax, and Cape Size. The six independent variables included the bulk carrier fleet volume, iron ore traffic volume, ribo interest rate, bunker oil price, and Euro-Dollar exchange rate. The dependent variables were handy size (32,000 DWT) spot charter rates, Supramax 6 T/C average charter rates, Pana Max (75,000 DWT) spot charter, and Cape Size (170,000 DWT) spot charter. The study examined charter rates by size of bulk carriers, which was different from studies on existing specific types of ships or fares in oil tankers and chemical carriers other than bulk carriers. Findings revealed that influencing factors differed for each ship size. The Libo interest rate had a significant effect on all four ship types, and the iron ore traffic volume had a significant effect on three ship types. The Ribo rate showed a negative (-) relationship with Handy Size, Supramax, Panamax, and Cape Size. Iron ore traffic influenced three types of linearity, except for Panamax. The size of shipping companies differed depending on their characteristics. These findings are expected to contribute to the establishment of a management strategy for shipping companies by analyzing the factors influencing changes in the freight rates of charterers, which have a profound effect on the management performance of shipping companies.

This study analysed the programming attitude and degree of achievement as the 6 types of learning styles which is suggested by Grasha and Reichmann(1974) after a performance of the programming education using the Diki-3000 which is the teaching tools of the specific manipulative activities, in order to prepare the programming education method according to the characteristics of elementary school learners. As the result of the study, the programming attitude according to the 6 types of the learning styles has indicated more positiveness in the independence type than in the dependence type, in the competition type than in the cooperation type, in the participation type than in the avoidance type. In the side of the degree of the achievement, the independent, competition, and participation types indicated more positive than the other types. Also, as the result of an structured interview with learners, which was conducted for deep understanding, there was an understanding of differences of requests to the programming learning classified by the learning styles, and suggestion of a plan for improvement of the Diki-3000 programming in the aspect of an educational environment, teaching tools, teaching contents, and teaching methods in this study.

The purpose of this study is to give the results of economic feasibility of industrial forest plantations, and also A/R CDM project in Indonesia to investors. In order to analyze economic feasibility of the industrial forest plantation and A/R CDM project, this study comparatively analyzes the feasibility based on three following scenarios: industrial plantation type; A/R CDM type; combination type of industrial plantation and A/R CDM project. In the aspect of IRR, the combination type has 11 % while the industrial plantation type has 8%. If the price of timber increases USD $5/m^3$ (from the standard price: USD $30/m^3$ to USD $35/m^3$), IRR of the industrial plantation type will increase from 8% to 14%. This result shows us that the IRR of the industrial plantation type is very sensitive to the price of timber. There is no economic feasibility of A/R CDM project if the price of lCER is under USD 5. In addition, IRR of the A/R CDM project type is the same to IRR of industrial plantation type (8%) when the price of lCER is USD 10. Finally, the total investment expenditure on 12,000ha of the combination type is approximately 13 billion won while the industrial plantation type is 13.6 billion won. It takes 11 year to reach the turning point in terms of profitability of the combination type while the industrial plantation takes 13 year. Thus, the economic feasibility of the combination type is higher than the other types(industrial plantation type and A/R CDM project type).

Component-based development(CBD) has been generalized in industry to master the complexity and reduce the development cost and time. However, current CBD practice is developing the component which is dependent on single application[l][2]. Therefore component variability is emphasized to reuse the component in many family members in a domain[8]. However, components are developed for the reason of replaceability rather than the reusability which is the main purpose of the component due to the insufficiency of the study of component variability definition and type[3]. In this paper, we formally specify the component variability reflecting the characteristics of the component to increase the component reusability. We define the logic variability which was recognized as the existing component variability and we propose all types of variability existing in the component by suggesting three more variability types. And we propose the component variability scope which makes us estimate and verify the number of cases of the variability when we customize the component. We propose these component variability types and scope through formal specification. By applying these techniques in developing components, we can develop high quality components reusable in many family members.

The purpose of this study is to analyze the cognizance of North Korean refugee by applying Q methodology, as well as to provide preliminary data for improving North Korean refugee's image. The study process let P sample, the study participants, use Q-sorting methodology to sort Q sample, which is composed of statements. 18 participants sorted 32 statements and 3 types of North Korean refugee cognizance were produced as a result. Those types are 1(N=8), 2(N=6), and 3(N=4), which are type favorable, type whereas negative stereotypical, and type neutralist. Favorable types agreed to ensure North Korean refugee groups' rights as a general protection, whereas negative stereotypical types had strong discrimination and prejudice towards North Korean refugee groups due to lack of related knowledge. Furthermore, neutralist types showed an objection to negative stereotypes against North Korean refugee, but they did not entirely agree to North Korean refugee either. It is necessary to develop a detailed strategy to improve the social image of North Korean refugee.

To extend the potential benefits of error, the current study examined factors that affect students' error perception in classroom. An experimental design was used to measure relations of classroom goal structure, feedback, and social relationships on students' perception of error. A total 316 fourth, fifth, and sixth graders attending elementary schools participated as part of their regular class curriculum. Self-reported questionnaires were administered to measure students' perception of errors and relationships with teacher and peers, then students were manipulated by classroom goal structure and feedback. Results from multiple regression suggest that students' perception of learning from error has affected by relationships with peers at the most, then relationships with teacher and the type of feedback. Students' perception of risk taking for error also affected by relationships with peers and teacher, then the classroom goal structure. However, no classroom goal structure and feedback affect on their perception of thinking about error to improve their learning as well as error strain. These results imply how classroom climate should be structured to improve perception of errors to improve student's learning.

This study aims to analyze classification systems used in the public sector, collected based on legislation, and to improve the classification system for public records. From the Korean Law Information Center, 375 legislative clauses were searched, revealing about 80 classification systems. These systems were initially divided into lists, tables, and hierarchical classifications. Six types of classification system uses were proposed after combining three management types and two system functions. Among these models, classification systems used for core operations in public agencies often had the same entity as both developer and user. While systems adopted from other institutions were often modified as needed, they were predominantly used for reference tasks rather than core operations. However, in records management, crucial tasks such as record classification and disposal commonly use unmodified classification system items developed and managed by other agencies. Consequently, this study proposes that structural improvements are necessary for the record classification system. It suggests developing dedicated classification systems to support core functions or modifying existing systems and also applying records management disposal standards and guidelines to other relevant legislative provisions.

This study takes note on the need for the consideration of the relationship between the service contents and service space which libraries provide, since at the moment the demands of library users, purpose of using it, etc. gradually become varied. In this study, type classification of public libraries was done focused on the relationship between service contents and service space, targeting Japanese public libraries. Through linking approach between service contents and service space, the analysis of Japanese public libraries' characteristics and type characteristics could be captured. This study has ultimately aimed to prepare for the basic data which will help Korean public libraries to make connection between service contents and service space in the future. The collected service contents and service space had been analyzed by multi-dimensional data analysis methods such as the "Quantification Theory Analysis Type III" and "Cluster Analysis". After characters of libraries were analyzed, the findings of this study show the views such as "the field of information provided, the method of information provision, and the object of service provision." And types of 44 libraries are classified into those which have 6 kinds of characteristics as follows : (1) group-oriented libraries which provide the jobs and employment information, (2) libraries which provide the jobs and employment information through the counselling space, (3) individual-oriented libraries which provide the information of education-related fields, (4) group-oriented libraries which provide the information of education-related fields, (5) libraries which provide information focusing on the counselling space, (6) individual-oriented libraries which focused on the service provision.
