The purpose of this study is to analysis the impact on the inside of the new city when an incidents occurs on the Songdo International City connecting road, which has a limited access. The analysis data used KTDB's O/D and network data of the Seoul metropolitan area. In addition, the scenario composition applied a method of reducing the number of lanes on the road according to the situation of incidents, targeting bridges advancing from Songdo International City to the outside in the morning peak hours. The analysis method analyzed the traffic volume, total travel time, total travel kilometer, and route change in the new city based on the results of the traffic allocation model. As a result of the analysis, the range of influence was shown to two types. First, of the seven bridges, Aam 3, Aam 2, and Aam 1 were analyzed to have an impact only in some areas of the northwestern part of the new city. On the other hand, the remaining bridges were analyzed to affect the new city as a whole. The analysis results of this study are expected to be used as basic data to establish the scope of internal road network management when similar cases occur in the future.

This thesis sets out to study the immanent mechanism of architecture which had classified as external spaces in general. As human controls a space, it controls or manages human's behavior, too. This study is depended on the humanities to analyze a various operation of power in the architectural space. It makes a comparative study of a space-power in a dwelling space through a discourse of Michel Foucault and Jacques Lacan, in particular everyday's microscopic scope. According to analytical results, the space-power of dwelling falls under the influence of a spacial arrangement and subject's desire. It has shown a noticeable characteristics in aspects production & consumption, using behavior, and use value. As it is seen through the aspects of production & consumption, owns of the space-power in a dwelling could not be its subject. We have also understood about a physicalistic furniture at the using behavior, it has a special power unconsciously to control a human's action and lifestyle. And then in the aspects of use value, the centric theme is a television. It lies on the core of space-power in dwelling, because is profoundly related to an innate respect of a dwelling value. In conclusion, so this study has the important meaning in the side to offer some interpretative possibility about the architectural space-power through a microscopic structure.

The aim of this study was to examine determinants of secondhand Bulk carrier and Oil tanker prices. This study compiled S& P transaction data taken from the Clarksons Research during J anuary 2018 to April 2022 to see how independent variables influenced secondhand ship prices. In the secondhand ship pricing model of entire segments, size, age, and LIBOR showed significant effects on prices. A vessel built in J apan and Korea was traded at a higher price than a vessel built in other countries. In the bulk segment, size, age, Clarksea index, LIBOR, and inflation were meaningful variables. In the Tanker segment, unlike Bulk carrier, only size and age were useful variables. This study performed regression analyses for various sizes of Bulk carriers and Oil tankers. It verified that impacts of variables other than ship size and age were significantly associated with ship type and size while macroeconomic variables had no influence except for bulk carriers. By applying diverse variables affecting secondhand ship price estimation according to various sizes of Bulk carriers and Oil tankers, this study will expand the scope of practical application for investors. It also reaffirms prior research findings that the secondhand ship market is primarily market-driven.

Pilots and navigators have through history used everything available to support them in the execution of their task. From the simple sounding means (for instance a stick or a line with a heavy object tied to it) to the advanced electronic support systems that are available today. This means that apart from the more traditional side of his set of tasks the influence of modern technology is felt. In general it concerns such diverse and complex subjects that it requires the pilot to remain up to date with regard to the most modern techniques. In a sense this also concurs with the change form a provider of (local) knowledge to that of a manager of a high risk operation. More information flows can reach the pilot on the place where he executes his profession. With marginal scope the pilot has to translate such information to the situation in which he finds himself in order to give a balanced advice. Knowledge of the surroundings, variable circumstances in his specific area but also language and culture play a crucial role. This paper touches on the history of pilot support systems and examines the developments of pilot support systems in the present day operating environment and addresses the implications. These range from the historic basic needs for pilot information to the present and future possibilities, supporting the pilot to make the most precise assessment at each operational stage to continually execute a safe journey in and out of port.

A school uniform has established it as youth culture and an important fashion cord which exposes adolescents themselves under the influence of TV and movies. Moreover as adolescents use TV and radio ads and Internet as a main source to purchase a school uniform, their effect on adolescents' school uniform fashion increasingly grows. The purpose of this study is to analyze design characteristics and chronological changes of school uniform design of high school girls and provide basic materials to develop school uniform design and predict adolescents' fashion trend. The scope and subjects of the study were limited to TV drama and movies which were shown from 1996 to 2010 and had high school students as their main characters based on youth culture. The analysis materials were photos of 50 school uniforms collected from TV soap opera, movies, web sites, DVDs, and Internet. First, the changes of a school uniform, the mass media and youth culture, and a school uniform in the mass media were reviewed through previous researches and literature review. Then, a form, color, and materials were classified to analyze the Dsign Characteristic. Finally, the changes were examined chronologically.

Although networking behavior is an effective job search method to students, far too little attention has been paid to mechanisms explaining the antecedents and networking behavior. The goal of this study was to demonstrate the effect of the HEXACO personality dimensions on graduated students' job search networking behavior through their network size. A survey of 773 participants was conducted to assess personality traits, network size, and networking behavior. All constructs in the study were measured by 5-point Likert scales. This study employed a structural equation model to examine the proposed conceptual model and the correlations among variables. Results showed that the personality of emotionality negatively influence students' network size, while extraversion and agreeableness are positively associated with the scope of their social network. Second, the findings confirmed that network size is directly related to the level of looking-for job behavior, particularly networking behavior. Finally, our results explored that network size played the mediating effect on how personality traits affect networking behavior. These findings suggest that network size is a dynamic mechanism that helps to understand the correlation between personality traits and job search networking behavior. The theoretical and practical implication of the study, as well as the future research direction were discussed.

In this study, self-supporting roofing elements especially convenient for large-span structures such as stadium, airport terminal, mall, coliseum, etc. were examined with respect to critical buckling load. These elements were assumed as laminated composite plates and, variation of free-edge forms, cutout types and lamination configurations were used as design parameters. Based on the architectural feature and structural requirements, the effects of curvilinear free-edge form on critical buckling load were focused on in this research. Within this scope, 14 types of lamination configuration were specified according to various orientation angle, number and thickness of plies with a constant value of total plate thickness. Besides that, 6 different types of cutout and 3 different free-edge forms were determined. By combining all these parameters 294 different critical buckling load analyses were performed by using ANSYS Mechanical software based on finite element method. Effects of those parameters on critical buckling load were evaluated referring to the obtained results. According to the results presented here, it may be concluded that lamination conditions have more significant influence on the critical buckling load values than the other parameters. On the other hand, it is perceived that curvilinear free-edge forms explicitly undergo changings depending on lamination conditions. For future work, existence of delamination might be considered and progression of the defect could be investigated by using non-linear analysis.

Objectives: The purpose of this study is to investigate the interaction and satisfaction of with web-based lectures. In addition, it seeks identify their correlations as well as the factors that influence satisfaction. Methods: The study subjects consisted of 139 college students taking up dental hygiene from Suncheon. ANOVA, correlation analysis, and regression analysis were used on the data collected. The Cronbach's alpha for interaction and satisfaction were 0.949 and 0.921, respectively. Results: The interaction recorded was moderate compared to face-to-face lectures. In particular, interaction between students was higher among 3rd grade students compared to those in the 1st grade (p=0.002). Satisfaction with the appropriateness of lecture content and duration was high, but relatively low in terms of the quality of the lecture and the desire to broaden its scope. In particular, satisfaction was higher among students in higher grade levels than their more junior counterparts (p<0.05). It was also found to be positively correlated with interaction (p<0.01). Their respective presence on the educational platform had the greatest impact on satisfaction (β=0.495, p<0.001). Conclusions: Increased interaction results in greater levels of satisfaction. Furthermore, an improvement in the quality of the lectures and the students' perception of them would enable lectures to be conducted more effectively in situations wherein face-to-face lectures cannot be done.

An internal finishing process applying Magnetic Abrasive Finishing (MAF) was proposed to produce smooth inner surfaces of tubes at a high rate. Since this process uses the tube rotation system, it has been considered applicable only to tubes which are rotatable at high speeds. Here development of the stainless tube(STS 304) rotation system to extend the scope of the application of the internal finishing process applying MAF was made. By the stainless tube(STS 304) rotation system, the abrasive magnetically attracted by the poles is rotated along the inner surface of the tube by magnetic force together with fixed poles, finishing the inner surface of the tube. The main results obtained are as follows : 1) The magnet abrasive finishing minimized influence due to external force because non-contact finishing, 2) The profile of surface roughness decreased very good in 11.4m/min range because abrasive size and speed, 3) The profile of surface roughness by flux density decreased in finishing speed 28m/min, 4) The profile of surface roughness by fled rate decreased in 0.16mm/rev and 0.18mm/rev.
