With several problems being pointed out with the rapid growth of online advertising markets, false, exaggerated or sensational advertisements are increasing. Particularly, the sensational appeal of online advertising is placed in the blind spot of deliberation on advertisements with any social consensus on the deliberation on online advertisements not made yet. According to these reasons, regulation and maintenance of the deliberation system are required for online advertising. In this study, content analyses on visual and verbal sensationalism in 2,009 advertisements were carried out based on 32 national online news services. According to the analyses, obscene advertisements on online news services are more than serious. In this study, based on the analyses, need for deliberation and regulation on online advertising is raised and direction of the deliberation on desired advertising is explored. In the future, effective advertising deliberate models need to be constructed through gathering opinions of the various members of the online advertising industry, such as advertisers, advertising agencies, media representatives, and publishers, etc.

This experiment was conducted to get the fundamental information about the difference in color and some chemical components of grey flue-cured tobacco cultivated in paddy field to compare with normal tobacco. Cured leaves of NC82 were separated with visual characters into three classes of slight, fair and severe symptoms of grey leaf by percentage of grey parts to whole leaf area, and compared to normal ones. Occurrence of grey leaves tended to be higher in lower stalk position than in upper ones. Cl, Mn and Fe content of grey leaves was much higher when it compared with normal leaves, and within the same leaf, grey parts were increased in Fe, Mn and Cl content than in those of normal parts but there was no appearent difference in total sugar, nicotine and Ca contents. Chemical analysis of grey leaf samples indicated that they contained more Fe, Mn and Cl contents than those of normal leaves. These tendencies in chemical traits were accordance with the degree of grey symptoms. Grey leaves showed remarkably lower b*value and slightly lower L*value than those of normal leaves, while a*value was mostly higher in grey leaves. In general, grey appearence of grey flue-curd tobacco seemed to be from less yellowish color, poorer brightness with more brownish or reddish color.

This objective of this study is to thoroughly analyze the policies of international organizations and major advanced countries relevant to the realization of Green port To construct Green ports, there first must be competition to build such ports in sustainable, fixed quantities. Second, there is a great need for cooperation and support networks made binding by mutual agreements on ship recycling. Third, there is a need for scientific research on responses to changes in environmental regulations and on environmental issues. Today, the majority of the world's ports use gasoline or electric energy, and improving capacities for self-sufficiency through development of new and renewable energy is judged to be a pressing task. The conditions for an eco-friendly port is that it must be an important center for economic and industrial activity, and valuable as a site where people live and work, with residences and work places existing in close proximity.

After 1970-80's rapid economic and urban development, nowadays the old downtown suffers from the deterioration of physical environment, outflow of its function and cavitation of population. And this phenomenon makes urban regeneration as a new paradigm in urban development. This is the case of Myeongdong area (Jungang-dong, Monsung-dong), old downtown of Cheonan around rail station, in the same way. City government has tried many regeneration/ redevelopment projects on this area but all failed due to lack of feasibility. This study intends to suggest new viable strategic regeneration scheme of this area through research and analysis of TOD development, existing condition and problems. As a result, the area needs to be considered as a node that links bus terminal complex and central market place with walkable street. For regeneration of this area, a strategic development scheme of this area is suggested deploying private capital invested rail station, underground shopping mall, transfer center, culture complex and nature park with Myeongdong street mall.

This study is on the simulation conditions of the tentative 'mobilization simulation mode'(MOBSM) and the setting option of major simulation elements. The MOBSM is a training module that practices mobilization of various institutions through a simulation computer similar to actual situations. So far, mobilization exercise(Mob-Ex) is a message simulation method, so it is necessary to convert into a MOBSM because many problems such as fragmentary and practice only by some institutions are raised. Therefore, the theoretical background and previous studies on Mob-Ex and simulation were reviewed to derive the requirements and simulated elements of the MOBSM to meet the purpose of government level exercise and to suggest the critical concepts and the direction of application. The basic requirement is to simulate the main mobilization practices by institution and provide information on the mobilization execution in a nationwide scope. The simulation elements are simulated events and flow charts by mobilization type, simulated range and level by object, simulated contents of material mobilization by institution, key simulated items, DB application, and simulated period, etc. This study will be useful for policy establishment and follow-up research for technology development of MOBSM in the future, and will accelerate the transition to practical mobilization exercise by MOBSM.

강이나 하천에 이수 및 치수의 목적으로 소규모 댐이나 보 등의 수리구조물을 설치한다. 수리구조물의 상하류부에는 하천 하상의 극심한 침식인 국부세굴현상을 방지하여 수리구조물의 안정성을 확보하기 위해 하상보호구조물을 설치하는데, 특히 하류부에 설치하는 하상보호구조물에는 크게, 다양한 형식과 크기의 물받이공, 에너지 감세공, 그리고 끝턱구조물 등이 이에 속한다. 지금까지 국내 외 수리구조물 설계지침에서는 하상보호공의 적절한 길이규모를 산정하기 위한 다양한 공식이 개발 및 적용되었지만, 최근 들어 다양한 목적을 위해 복잡해진 수리구조물의 형식과 다양한 운영방식에 따른 수리학적 분석내용이 적절하게 반영되지 않은 경험공식이 대부분 적용되었다. 따라서 예상보다 매우 큰 하상유실이 발생 하여, 하상보호구조물의 설치역할을 제대로 수행하지 못하고 오히려 수리구조물의 안정성에 위협을 주는 주요한 요인이 되었다. 그리고 최근 국내에는 4 대강 유역에 16개 중 대규모의 다목적 보가 설치되었으나 앞서 언급한 바와 같이 미흡한 설계지침을 기반으로 설치된 보 및 하상보호구조물의 기능이 저하되어 극심한 세굴현상이 발생하였다. 또한 이를 보강하기 위한 추가적인 공사 등으로 경제적인 손실을 야기하였다. 반면 외국의 최근 설계지침에는 하상보호구조물 하류부에서 발생하는 평형최대세굴심의 규모를 고려하거나 흐름 및 난류분포를 고려한 수리학적 분석이 반영되어 있지만 국내 설계지침에는 전무한 실정이다. 따라서 본 연구에서는 기존 국내 설계지침의 한계를 조사하고 현재 외국에서 적절하게 제안되어 적용 중인 하상보호구조물 설계지침을 검토하였다. 특히 수리학적 거동특성과 유사분포 특성이 고려된 최대세굴심 산정공식과 설계지침을 검토하였고, 평형상태에 도달한 세굴공 내에서의 수리학적 특성을 고려하여 하상보호구조물의 길이를 적절히 산정할 수 있는 기존 연구결과를 토대로, 하상보호구조물 길이 산정공식을 제안하였다. 본 연구에서 검토된 외국 설계지침과 함께 수리학적 거동특성이 고려된 하상보호구조물의 길이 산정공식은, 향후 수리구조물의 안정성 확보를 위한 하상보호구조물의 설계에 반영될 필요가 있으며, 이를 통해 수리구조물의 효율적이고 경제적인 유지관리를 위해 적절히 활용될 수 있다.

This study aims to examine the effects of the main eight items amended in the 2013 child care center accreditation system and to provide suggestions. The participants in the study were 200 child care center teachers and staff; 150 professionals consisting of public officials in charge of child care, members for the accreditation committee, and inspectors at the site; and 144 parents. They participated in an on-line questionnaire survey conducted during the end of February, 2014. The survey questions regarding the eight changed items were the same to all the three participating groups, and three more questions were asked to child care center teachers and staff. The collected data were analyzed with frequencies and percentages to present general recognition level. For a group comparison, analysis of variance was first performed among 3 professional groups, all of which has the same size. When there was not a statistically significant difference among the three groups, the second analysis of variance was done among three groups of professionals including the three groups, teachers and staff, and parents. The results showed that there were differences in recognition among the groups regarding each changed item in the 2013 child care center accreditation system, but overall, the groups evaluated the main amendments positively and the changes were considered appropriate and necessary. However, it was found that in-depth reviews are needed of procedure unification to check the basics to require legal compliance; management of unaccredited centers such as valid period reduction and no accreditation, or limit for re-accreditation application; and the burdens of child care centers about surprise visits and notice of inspection dates in advance.
