Under the assumption that people go through stages in making dietary behavior change, this study was attempted to apply the stages of a change model for fat intake by examining the associations of social psychological variables with stages of change in dietary fat reduction. Derived from social psychological theories, 10 social psychological variables on motivational beliefs(6), social influence(3) and self-efficacy(1) related specifically to selecting every day diets low in fat were constructed. Fat and energy intakes were assessed by a short form semi-quantitative food frequency questionnaire. The associations of stages of change with motivational beliefs, social influence, and self-efficacy variables and energy and fat intakes were assessed in 333 female adults from large cities in Korea. Dietary stage groups differed significantly on most of the social psychological variables in ways predicted by theory. Motivational factors that lead to a psychological state of readiness to take action were important in the early stages of the dietary change process. Social influences were more important in the stages as people decide to take action. Self efficacy and motivational beliefs, particularly, reduction of perceived barriers were important in maintaining fat reduction behavior. The results of our study indicate differences in stages of change in fat reduction behavior in terms of nutrient intakes and social psychological correlates and suggests that adding a time dimension to social psychological models increases our understanding of dietary change, which assist us in designing nutrition education interventions that are more appropriately targeted by stage of change.

In the Republic of Korea, mathematics has always been a major blame for huge private expenditures on so-called "private education," which consists of private tutoring and lessons at "private academies of extra curricula." The private spending on out-of-school education often exceeded public expenditures on schools. In 1997, South Korean Ministry of Education reformed curriculum of mathematics along with other subjects to ease the burden of private education. The aim of this curriculum change was to put a boost on individual students' interests, affections and other attributes toward school mathematics. The essential distinctiveness of the new curriculum of mathematics compared with the previous one is as follows: 1. The implementation of so-called "differentiated curriculum" for grades 1-10. 2. 30% reduction of contents in mathematics and the reconciliation of contents. 3. Elective subjects for mathematics for grades 11 and 12. 4. More uses of technology in mathematics teaching. Firstly, we examine the background of the curriculum reform and analyze the new curriculum according to awareness of educational administrators, teaching environments of schools and readiness of mathematics teachers. Then we find out what kinds of problems it has and look for some suggestions for remedies.

The mechanism of micro machining of reacted layer on silicon surface were proposed. The depth of reacted layer and the change of mechanical property were measured and analyzed. Depth of hydrated layer which is created on the surface of silicon by potassium hydrate was analyzed with SEM and XPS. The decrease of the micro victors hardness of silicon surface was shown with the increase of the concentration of potassium hydrate and the change of the dynamic friction coefficient by chemical reacted layer was measured due to the readiness of machining. The experiment of groove machining was done with 3-axis machine with constant load. With chemical mechanical micro machining the surface crack and burrs generated by both brittle and ductile micro machining were diminished. And the surface profile and groove depth was shown in accordance with the machining speed and reaction time with SEM and AFM.

High-rise buildings often can accommodate the population of small horizontal cities. The investment in high-rise buildings is considerable and therefore a rapid return on investment is necessary. The immediate availability of high-rise buildings can be achieved by automated prefabrication of highly finished modules and their instant on-site assembly by robotic and automated construction sites. A high-rise building as a vertical city can be considered as a sophisticated organism that can constantly change throughout its lifecycle in response to economic growth, demographic change, and environmental pressures. To date, many new urban high-rise developments claim to be "vertical cities", yet few represent this important characteristic. This article analyzed the technological readiness and innovations in the field of construction automation and robotics including single-task construction robots, automated on-site construction factories, and ambient assisted living. These technological advances enable the realization of future vertical cities that are able to continuously grow and transform in terms of form and function. Finally, the article proposes a visionary archetype of vertical city in the name of "dynamic vertical urbanism" that is easy to expand vertically and horizontally in order to achieve instant availability and full life cycle resilience thanks to advanced building technologies.

북한 산림황폐화를 방지하기 위한 남북한 협력 수단으로 REDD 메커니즘의 적용 가능성을 사전 검토하였다. 북한은 기후변화협약이 국가 단위의 REDD+ 메커니즘의 이행 조건으로 요구한 REDD+ 국가 전략 수립과 산림모니터링 시스템 등을 구비하지 못하였다. 또한 북한은 REDD 메커니즘을 적용하기 위한 토대인 산림자원 통계의 신뢰성 역시 부족하였다. 인공위성 영상자료를 활용하여 추정한 산림면적 자료를 제외한 대부분의 산림자원 통계는 신뢰할만한 산림조사 결과를 바탕으로 하지 않고 단순한 가정을 기초로 추정된 것이다. 이러한 검토 결과는 북한이 산림황폐지 복구 수단으로 REDD 메커니즘을 당장 적용할 수 없다는 것을 보여준다. 이를 바탕으로 향후 REDD 메커니즘을 북한에 적용하기 위한 연구 주제와 남북한 산림부문의 협력 의제를 제안하였다. (1) 최소한 2000년 이후 북한지역의 토지이용변화 탐지, 탄소축적변화 추정 및 산림전용 산림황폐화의 원인 구명 연구가 필요하다. (2) 남북한의 REDD+ 협력은 북한의 'REDD+ 국가 전략 수립' 및 '국가산림조사 체계 구축' 부문에 초점을 맞추어야 한다.

Purpose: The purpose of this study was to investigate the stages of change in smoking cessation after a Coronary Artery Bypass Graft(CABG) and to identify the related factors. Methods: The subjects (n=157) were patients who underwent a CABG in a university hospital from March 1998 to October 2005 and were smokers before the CABG. Data was collected viachart review and a telephone interview, and analyzed with descriptive statistics, $X^2$ test, one-way ANOVA, and Kruskal-Wallis procedure by the SPSS/PC win 12.0 program. Results: The subjects smoked for an average of 34 years (21 cigarettes per day) before surgery. Eleven percent of the subjects were in pre-contemplation, 6.4% in contemplation, 13.5% in preparation, 4.5% in action, and 64.5% in the maintenance stage. Nicotine dependence and self-efficacy were different among the groups with different stages of change in smoking cessation. Nicotine dependence was the lowest (p=0.00) and self-efficacy was the highest (p=0.00) in the maintenance stage. The number of subjects in pre-contemplation and contemplation significantly increased 6 years after surgery(p=0.05). Conclusions: To implement effective smoking cessation interventions for CABG patients, the intervention should be developed to accommodate individual readiness for smoking cessation, especially so for those who had a CABG more than 6 years previously.

기후변화 문제와 그 해결을 위한 범지구적 대응은 다양한 측면에서 기업의 경쟁력에 영향을 미치고 있기 때문에 이에 효과적으로 대응하지 않는다면 기업의 경쟁력을 안정적으로 유지하기 어려울 뿐만 아니라 기후변화와 관련된 국가 전체의 경제적 비용이 크게 증가할 수 있다. 기업의 경쟁력은 대내외적인 여건 하에서 지속적인 생산활동과 이윤 창출을 위한 잠재력을 의미한다. 경쟁력은 직관적으로는 쉽게 이해되는 개념이지만 실제로 이를 결정하는 요인을 도출하고 그 변화를 측정하는 것은 복잡하고도 논란이 많은 주제이다. 이러한 문제를 해결하기 위해 일반적으로 사용되는 방법은 '경쟁력지수'를 개발하여 활용하는 것이다. 경쟁력지수는 기업이나 국가의 경쟁력을 일정한 지표체계와 복합지표 방법론을 이용하여 하나의 지수로 측정하는 방식이다. 기후변화는 물리적 피해, 온실가스 규제, 고정자산 감모, 제품 수요 변화 등을 통해 요소, 기술, 제품, 시장구조 등의 기업경쟁력 결정요인에 영향을 미친다. 따라서 기업 경쟁력은 기후변화라는 영향요인에 대한 취약성을 줄이고 새로운 대내외적인 여건에 성공적으로 대응하여야만 안정적으로 유지할 수 있다. 본 연구는 기업의 경쟁력에 영향을 미치는 요인을 도출하고 이를 반영한 주제별 지표체계 및 지수 개발을 목적으로 한다. '기후변화 경쟁력지수'는 기후변화 요인에 따른 경쟁력 변화를 정량적으로 측정할 수 있는 도구를 제시함으로써 기업의 기후변화 대응 능력 제고와 산업계에 대한 기후변화 정책을 효과적으로 운영하는데 기여할 것으로 기대된다.

Purpose - This research is aimed to investigate the impact of the Information and Communication Technology (hereinafter ICT) development index and ICT investment on Indonesian economic growth. Research design, data and methodology - The data used consist of ICT development index, government expenditure on ICT sector, and economic growth from 33 provinces in Indonesia from 2012 to 2015. Based on the Networked Readiness Index published by the World Economic Forum (WEF), Indonesia was ranked 80^th among 142 countries in 2012 and had climbed 64^th in 2014. This indicates that the businesses in Indonesia have adopted ICTs to increase productivity and expand their activities. Panel data regression analysis is performed to reveal the change of the impact over time in each of the provinces. Result - The ICT development index and government expenditure for ICT have a positive effect on the economic growth of all provinces, although the impact is different in each of the provinces. There is a digital gap between the provinces, especially the large digital gap occurring with DKI Jakarta. The provinces of Eastern Indonesia such as NTT and Papua are still relatively slow in development of ICT. Conclusions - ICT development index and allocation of local government expenditure for ICT have significant effect on economic growth. ICT development index has a bigger role in increasing economic growth.
