On the basis of Flügge shell theory, the vibrations of single walled carbon nanotubes (SWCNTs) are investigated. The structure of armchair single walled carbon nanotubes are used here. Influences of length-to-diameter ratios and the two boundary conditions on the natural frequencies of armchair SWCNTs are examined. The Rayleigh-Ritz method is employed to determine eigen frequencies for single walled carbon nanotubes. The solution is obtained using the geometric characteristics and boundary conditions for natural frequencies of SWCNTs. The natural frequencies decrease as ratio of length to diameter increase and the effect of frequencies is less significant and more prominent for long tube. To assess the frequency confirmation carried out in this paper are compared with the earlier computations.

본 연구는 부산광역시 거주민을 대상으로 원전주변 갑상선암 피해 소송 이후 원자력발전소 인근지역과 시내권에 거주하는 주민간의 인식 차이를 분석하여 국민들의 원자력에 대한 수용성 수준을 판별하고자 하였다. 설문조사는 총 551명(원전인근지역 269명, 시내권 282명)을 대상으로 대인면접을 통해 이루어졌으며, 분석 결과, 원전 주변 갑상선암 발병 피해 소송 사건을 계기로 국민들의 원자력에 대한 인식에 변화가 있는 것으로 나타났다. 원전인근지역 주민의 경우 사건 이후 원자력에 대한 불신과 불안감이 높아져, 원자력에 대한 부정적 인식이 강해졌음을 확인할 수 있었다. 반면 시내권 주민들은 원전 주변 갑상선암 발병 피해 소송 사건에도 불구하고 사건 이전보다 더욱 원자력 수용성에 긍정적인 인식을 갖는 것으로 분석되었다. 그러나 원자력 안전성과 신뢰성에 대한 인식은 부정적인 것으로 분석되어 원자력 수용성과 상반되는 이중적인 인식을 보였다. 이는 부산광역시 시내권 주민들의 경우 원자력의 편익, 필요성 등을 원칙적으로 인정하나 안전성에 대해서는 의심하는 것으로 판단되며 향후 원자력의 이용 확대를 지속적으로 추진하기 위해서는 국민의 올바른 이해와 신뢰 그리고 무엇보다 국민 또는 원전인근지역 주민들과 충분한 의사소통이 필요하다고 사료된다.

In this study, it propose what the landscape elements is to be improved urgently and how to improve landscape by reflecting the rural village characteristics away from the spatial integrated landscape planning. The study area for landscape research is selected as the 9 rural villages in Chungcheongbuk-do, and research is done by using village unit landscape diagnostic index(VULDI). the result is shown that average VULDI value of the rural village zones is bigger than one of the town village zones with difference of 15%. Two zones of Chilseong-myeon and Sangchon-myeon among the town village zones are appeared to be similar with the rural village zones in landscape level by VULDI value. Generally, the rural villages to maintain the good landscape have the low population and high engagement rate in agriculture. Looking political support criteria at the landscape level, the seven zones except Deoksan-myeon and Maengdong-myeon have high VULDI value more than 60%, which means that it seems unnecessary to support political landscape improvement. However, when it is divided into two parts of the village inside landscape and the surrounding landscape, 8 rural village zones except one zone of Sangchon-myeon have low VULDI value less than 60%, which means it is necessary to support political landscape improvement. It is important to give the intensive support of ever urgent landscape improvements and high priority landscape elements on the results of the diagnostic before planning of the rural landscape formation.

Seoul has been the former capital from Joseon founded in 1932 by this time for 600 years. Seoul populated by some 10,290,000 people is the largest city in Korea. There are lots of cultural inheritance such as the castle town and 5 palaces including Gyeongbokgung in Seoul. Especially neungs(royal tombs) from 27 generations of king and queen in the Joseon dynasty during 518 years are very important cultural inheritance. The royal tombs were built from the castle town to the radius outside 4km within 40km pivoting on Seoul. Joseon royal tombs might have significant cultural value, which are representative Korean people's spirits for ancestor worship. After the 1945 Liberation of Korea those are having been managed by Office of Cultural Properties after Ministry of Education. This paper tried to find the changing process of the conservation and maintenance, the location of royal tomb area, the changing process of royal tomb, the area changing clue of modernization process, and in the historical city, Seoul. The royal tombs in the Joseon dynasty of the radius outside 4km within 40km pivoting on Seoul have been contributed to providing the metropolitan, Seoul population with the cultural and green spaces for 600 years. In the Joseon dynasty the royal tombs had been taken charge of thoroughly by the Royal Household with Neungchamboing system from Confucian background for ancestor worship. There after they had been damaged somewhat by the Japanese Imperialism period, the Korean War, and the pressure of urbanization. But the original state has been preserved well by state management. The royal tombs in the Joseon dynasty has been kept the culture of royal tomb's and memorial services with stone sculptures for 518 years. Also there are lots of documentary records of royal tombs. The memorial services of the tombs are held by Jongyakwon of Jeonju Lee family every year. The royal tombs somewhat damaged are needed to the original state of the transferred right of managing agency by the related national bodies.

Objective: Prior functional magnetic resonance imaging (fMRI) work has revealed that children/adolescents with disruptive behavior disorders (DBDs) show dysfunctional reward/non-reward processing of non-social reinforcements in the context of instrumental learning tasks. Neural responsiveness to social reinforcements during instrumental learning, despite the importance of this for socialization, has not yet been previously investigated. Methods: Twenty-nine healthy children/adolescents and 19 children/adolescents with DBDs performed the fMRI social/non-social reinforcement learning task. Participants responded to random fractal image stimuli and received social and non-social rewards/non-rewards according to their accuracy. Results: Children/adolescents with DBDs showed significantly reduced responses within the caudate and posterior cingulate cortex (PCC) to non-social (financial) rewards and social non-rewards (the distress of others). Connectivity analyses revealed that children/adolescents with DBDs have decreased positive functional connectivity between the ventral striatum (VST) and the ventromedial prefrontal cortex (vmPFC) seeds and the lateral frontal cortex in response to reward relative to non-reward, irrespective of its sociality. In addition, they showed decreased positive connectivity between the vmPFC seed and the amygdala in response to non-reward relative to reward. Conclusion: These data indicate compromised reinforcement processing of both non-social rewards and social non-rewards in children/adolescents with DBDs within core regions for instrumental learning and reinforcement-based decision-making (caudate and PCC). In addition, children/adolescents with DBDs show dysfunctional interactions between the VST, vmPFC, and lateral frontal cortex in response to rewarded instrumental actions potentially reflecting disruptions in attention to rewarded stimuli.

When constructing buildings, planning, design, construction, using & maintenance as building life cycle. Due to industrialization in 1960s and development of new town from the late 1980s to the early 1990s, Korean housing supply rate reaches almost 100%. After construction companies confronted limit of new building construction, they recognized remodeling as a part of construction, and organized remodeling team or FM team to improve sustainable industrial area. However, since companies in Korea are lack of experience and research activities for remodeling, it makes obstacle to improvement of remodeling business. So the objective of this study is to help carry out remodeling business by suggesting the counterplan through investigation of a risk of apartment remodeling business.
