Objectives: This study examined the extent to which attitudes about smoke-free air policies (SFAPs) in bars/restaurants, workplaces, all public places, and motor vehicles when minors are present can be explained by individuals' sociodemographic characteristics, smoking status, and beliefs about the health of others. Methods: Data were gathered from 359 individuals age 18 or older who attended the Lawrence County Fair in Indiana, United States, in July, 2009, an area where there were no SFAPs in place at the time of survey administration. Results: Multinomial logistic regression analyses indicated that perceived severity of secondhand smoke (SHS) on others, perceived responsibility of smokers for the harm their SHS causes to others, and perceived susceptibility of others to SHS exposure, along with education level and smoking status, significantly predict opposition to SFAPs in this population. Conclusions: The results of this exploratory study suggest the need for additional research related to attitudes about health policies as well as to the practical applications of these findings for smoke-free air advocacy.

Serial extraction procedure, when cautiouly practiced in severe discrepancy case, can be a good clinical approach, but the treatment planning must always be based on accurate analysis of all conditions, especially patient's individual growth pattern and his family development. It is most difficult to determine the timing and selection of most effective sequence of deciduout extraction. It is the best candidate that patient is with class I malocclusion with harmony of the skeletal and muscular system and severe discrepancy of the tooth system. The authors have observed a female, who has complained of the malalignment of mandibular permanent incisor teeth. Serial extraction has been performed to relieve it through adequate various informations and resulted in a fairly good prognosis.

In this thesis, to accurately measure 3D face information using the spatial encoding patterns, the new algorithm to segment the pattern images from initial face pattern image is proposed. If the obtained images is non-homogeneous texture and ambiguous boundary pattern, the pattern segmentation is very difficult. Furthermore. the non-encoded areas by accumulated error are occurred. In this thesis, the FCM(fuzzy c-means) clustering method is proposed to enhance the robust encoding and segmentation rate under non-homogeneous texture and ambiguous boundary pattern. The initial parameters for experiment such as clustering class number, maximum repetition number, and error tolerance are set with 2, 100, 0.0001 respectively. The proposed pattern segmentation method increased 8-20% segmentation rate with conventional binary segmentation methods.

The Fallingwater, one of Wright's best designs, is known as a good example of "Organic Architecture". Its landscape characteristics are harmonious relationship between architecture and landscape, adaptable siting, composition of spatial and visual structure, floating spaceness, interlocking of water and house, dramatic approach, and vernacular material use. This characteristics had begun from the Prairie architecture, but also had influenced by the culture and art of the Far East. He was open to foreign cultures. Staying in Japan for years, he had travelled China, too. In this process, he might be exposed to Korean art and culture which were under Japan at that time. Comparing the front image of the Songkwang Temple to that of the Fallingwater, their compositions between architecture, water, and landscape are so similar to each other. They are also close to each other in terms of spatial structure. Therefore the landscape characteristics found in the Fallingwater design are more similar to Korean landscape architectural characteristics than Japanese ones. Therefore we are going to suggest the hypothesis that Wright is influenced by Korean landscape design in the design of the Fallingwater. Considering his impact upon the design world, it will be significant if the concept of Korean traditional landscape design is placed behind his design of the great architecture.hitecture.

The firms with OHSAS (Occupational Health and Safety Management System) registration should be audited every six months and they have to be reregistered every three years by a third party. In our article audit data were collected from the audit processes of fifty four firms that OHSAS 18001:2007 was implemented and audited by LRQA (Lloyd's Register Quality Assurance). Fifty four firms are largely classified as four categories: civil engineering and construction industry, metal and heavy industry, chemical industry, and other industries including electric, electronic, food, and services. Especially the minor conformity data are analyzed by statistical methods to find out the relationship between four categories of 54 firms and the average number of minor nonconformities. The most frequently appeared minor nonconformities among sub-requirements of OHSAS 18001:2007 are investigated and the reasons for minor nonconformities are specifically explained. The average number of minor nonconformities of firms before and after OHSAS 18001:2007 registration are compared to understand the maturity of OHSAS implementation. Some comments and suggestions are provided for OHSAS to be effectively implemented to the firms if revision is necessary.

In the resultant period of architectural transition and a tendency towards unthinking formalism, it is all the more important for designers to question the meaning of their actions and their role in society. Modern architects were convinced that their visions were reality, their ideas truth. Yet this assumption is was the fundamental issue, for what reality and how is it perceived? Harries argues a rediscovery of a language of natural symbols, which might help create buildings that are experienced as necessary rather than arbitrary. These symbols are said to express the essential patterns of human existence in the world. In the Frank Lloyd Wright's works, the uniqueness of his architecture lies in its expression and interpretation of nature and people's existence in the world. This study is intended to be an investigation of the nature of physical expression and perception of the reality known, and to seek to present Wright's philosophy of house design in relation to nature and non-arbitrary architecture. Finally this paper concludes that the architectural expression of expressions of Wright's houses are timeless and full of lift, and these built qualities are necessary and could not readily be otherwise.

Sloshing loads, produced by the violent liquid free-surface motions inside the cargo tank have become an important design parameter in ship building industry since there have been demands for the increased sizes of the cargo containment system of LNG carriers. In this study, sloshing impact pressure acting on the shell of the spherical cargo tank of an LNG carrier as well as dynamic pressure and flow behavior around the pump tower located at the center of the tank have been calculated. Comparative numerical sloshing simulations for a spherical LNG tank using 2-D LR.FLUIDS which is based on the finite difference method and 3-D MSC.DYTRAN which is capable of calculating nonlinear fluid-structure interaction have been carried out. A method of calculating sloshing-induced dynamic loads and the subsequent structural strength analysis for pump tower of a spherical LNG carrier using MSC. DYTRAN and MSC.NASTRAN have been presented.

고분자와 희석제 간의 interaction은 phase diagram의 형태로 결정하고 상분리 mechanism은 phase diagram에 의해 설명된다. Thermodynamic interaction이 TIPS 분리막의 구조에 미치는 영향을 조사하기 위하여 PP/C20alkane, PP/C20acid, PP/TA 3가지 system을 선택하였다. 200$^{\circ}$C에서 25 $^{\circ}$C로의 급냉과 분당 10 $^{\circ}$C의 냉각조건을 적용하였다. 각 phase diagram의 형태와 냉각조건에 따라 상분리 mechanism이 달라져서 서론에서 언급한 바와 같이 각기 특유의 구조를 갖게됨을 확인하였다. 같은 종류의 희석제의 chain length가 분리막의 구조에 미치는 영향을 조사하였다. 희석제의 chain length에 따라 결정화 온도가 달라지며 PP와의 결정화 속도 차이에 의하여 구조가 다양하게 변화되었다. 또한 가 희석제의 확산계수의 차이에 의하여 PP 결정화 시 희석제의 외부 방출 정도가 달라 이에 의한 구조의 차이도 관찰되었다. TIPS 공정에서 용액의 조성이 분리막의 구조에 미치는 영향을 조사하였는데, 조성에 의한 nucleation density의 차이에 따라 PP spherulite의 충돌 (impingment)등이 구조에 영향을 미쳤으며 porosity도 변화하였다. 또한 PP/TA system에서는 조성에 따라 상분리 mechanism이 달라져 현격한 구조의 차이를 보였다. 또한 냉각 속도에 따라 PP spherulitic structure가 변화함을 확인하였고, PP 결정화에 따른 희석제의 방출에 의하여 interspherulitic과 intraspherulitic pore를 갖는 2중 구조를 갖게 됨을 알 수 있다.

The optimum design of power yacht belongs to the nonlinear constrained optimization problems. The determination of scantlings for the bow structure is a very important issue with in the whole structural design process. The derived design results are obtained by the use of real-coded micro-genetic algorithm including evaluation from Lloyd's Register small craft guideline, so that the nominal limiting stress requirement can be satisfied. In this study, the minimum volume design of bow structure on the power yacht was carried out based on the finite element analysis. The target model for optimum design and local structural analysis is the bow structure of a power yacht. The volume of bow structure and the main dimensions of structural members are chosen as an objective function and design variable, respectively. During optimization procedure, finite element analysis was performed to determine the constraint parameters at each iteration step of the optimization loop. optimization results were compared with a pre-existing design and it was possible to reduce approximately 19 percents of the total steel volume of bow structure from the previous design for the power yacht.
