본 연구는 학습자 중심 학습을 핵심으로 하는 구성주의 박물관 교육 구현을 위해 학습 동기에 주목한 M-ARCS(Museum- ARCS) 척도를 개발하여 신뢰도와 타당도를 검증하는 것을 목적으로 한다. 이를 위해 구성주의 박물관 학습 특성과 ARCS 동기이론을 접목하였는데 이는 ARCS 동기이론이 한국 상황에 필요한 포괄성, 구체성, 문제해결성을 기반으로 하기 때문이다. 예비척도는 구성주의 박물관 교육의 학습 특징 지표와 ARCS 동기이론 체크리스트에서 추출한 후, CVR 검증과 자문을 받아 구성하였으며, 전문가 3인의 자문을 거쳐 3개 준거(프로그램 기획, 프로그램 운영, 활동지), 16개 세부준거, 77개 지표의 최종 예비척도를 마련하였다. 최종 예비척도 검증을 위해 전문가 201명 대상의 온라인 설문을 실시하고 10건의 박물관 교육을 참관하였다. 기술통계분석과 상하 27% 집단 독립표본 t-test를 통해 지표 양호도와 지표 변별도를 검증하였다. 확인적요인분석을 통해 표준화 계수가 낮은 10개 지표를 제외한 후 집중타당도를 입증하였고 판별타당도와 모형 적합도를 확인하였다. 또한 크론바흐알파 계수와 Kappa 계수로 신뢰도를 검증하였다. 이를 통해 구성주의 박물관 교육의 동기 설계를 위해 3개 준거, 16개 세부준거, 67개 지표로 구성된 M-ARCS 척도를 개발하였다. 마지막으로 M-ARCS 척도의 개발 의의, 제한점 및 제언을 논의하였다. The purpose of this study was to develop and validate the M-ARCS (Museum-ARCS) scale which focused on learning motivation, in order to implement the constructivist museum education based on the learning-centered learning. To this end, the ARCS model featuring comprehensiveness, concreteness, problem-solving necessary for motivational design in constructivist museum education of Korea was integrated. The preliminary scale was constructed based on constructivist museum education features and ARCS model checklists and integrated through after CVR value and consultation. The final preliminary scale was consisted of 3 categories(Program Planning, Program Implementation, Worksheet), 16 sub-categories, and 77 indicators after 3 experts’ consultation. An online survey from 201 experts and 10 museum education observations were conducted for validation of the final preliminary scale. The descriptive analysis and t-test of 27 percent upper and lower groups showed the goodness and discrimination of indicators. The confirmatory factor analysis was conducted and 10 indicators were deleted on Standard Regression Weight threshold. The convergent validity and the discrimination validity were confirmed and the model fit showed its appropriateness. The Cronbach’s alpha and the Kappa value showed its reliability. As a result, the M-ARCS scale constructed of 3 categories, 16 sub-categories, and 67 indicators for motivational design of constructivist museum education. Finally, the significance, limitations and suggestions for the development of the M-ARCS scale were discussed.

This analysis is to review whether PSD(Platform Screen Door) installed in local subway stations secures amenities of sound environment among the elements of developing pleasant station surroundings. Since there has been no specific noise standard for indoor subway station in the country, would like to suggest suitable criteria based on research on other similar domestic and foreign cases. Also, this study aims at whether PSD meets the noise standards of platforms and affects noise reduction through simulation of before and after installing.

Korean government has a goal to reduce 30% of the greenhouse gas emissions prospect(BAU base) by 2020. In order to fulfill this commitment, Korea has adopted a target management system and it plans to install a emission trading scheme by 2015. The GHGs reduction policy is expected to have a direct economic effect on energy costs including coal and electricity. This paper aims to analyze the empirical effects of such increases in energy costs on the steel industry. Empirical estimation is performed on the first differences of time series data over the 1971-2011 periods. Results show that an increase in coking coal prices has a negative effect on value-added in the steel industry. The rate of change in the electricity price is also shown to have an adverse effect on industry profits. As theories predict, GDP and prices of steel products have significantly contributed to the two performance measures. Policy implications include the need of special attention to those firms that are heavily relying on electricity energy in designing a country-wide emission trading scheme.

The surface layer in dredged and reclaimed marine clay is improved by mixing of shallow soils and hardening agents, which is made of cement, containing some other special admixtures. Tests in both laboratory and field settings are performed to investigate the improvement effect and strength properties of cement-stabilized soils. The test results show that the hardening agent sufficiently improves the soil properties of the surface layer, while increasing the load-carrying capacity. The strength of cement-stabilized soils depends, primarily, on water-to-cement ratio and curing temperature. That is, the higher curing temperature and the longer curing time, the higher the strength in cement-stabilized soils. The high ratio of water-to-cement results in a lower strength.

Oliver Goldsmith's play, She Stoops to Conquer, can be considered a comedy representative of the Restoration. Excluding the moral decadence and artificial grief common in comedies of manners or sentiment, this play serves as a pure laughing comedy which gives the audience unadulterated mirth. There are dichotomous oppositions between high and low classes, man and woman, and the urban and the rural which are seen in comic irony as depicted by Marlow as well as by the surrounding people, who mistake Kate's mansion for an inn. Analysing the element of class hidden in the comic irony, this article will identify the social contradictions and class consciousness that Goldsmith intends to satirize. His play protests against an aristocratic ideology typical of the bourgeois plays, giving it some of the traits of a social drama. The true intention of the author is not to judge someone as right or wrong, nor to punish him or her, but to accept the comedic aspects of each character's original identity.

As a result of very limited access due to the military confrontation between South and North Koreas for the last five decades, ecosystems in the transboundary coastal area in the western part of Korean Peninsula have been protected from intensive developments in both Koreas. In the core of the recent two military collisions lies the fishery resources represented as blue crabs as well as the politico-military aspect. Increasing development pressures from both sides as reflected in the South Korea supporting the construction of an industrial complex in Kaesung, North Korea, is the main factor which threatens the sustainable resource base in this region. This research is aimed to develop a cooperative management system for the well-preserved transboundary coastal area between South Korea and North Korea. The Pressure-State-Response (PSR) framework of OECD was used to assess environmental conditions, socioeconomic pressures on the environment of the region, and policy responses of both Koreas to those pressures. Protection of ecosystems, peace settlement, and prosperity of the region and the entire peninsula were proposed as the management goals of the cooperative management system. The designation of the area as a Co-managed Marine Protected Area System (COMPAS) through close cooperation among South Korea, North Korea, and international entities was suggested as a way to achieve those goals. Revision of legal and institutional mechanisms, strengthening knowledge base for optimal COMPAS management, integration of the marine protected area and DMZ (demilitarized zone) ecosystem, enhancing stakeholder participation, building international partnership, and securing financial resources were presented as six management strategies.
