Developed countries, especially in road construction and management fields, introduce new road porjects such as National Scenic Byways Program(NSBP program) in USA and the Eco-road project in Japan. This study develops a conceptual model for deploying new road projects in Korea. The four step approach is suggested to create new road projects, including foundation of an act based on the existing Road Act, creation of new road project ideas, development of evaluation process and guidelines, and enhancement of an administrative scheme. To create new road projects, three different ways are devised; (1) designation of national roads having uniqueness in overall spectrum, (2) designation of roads having intrinsic values in a different aspect, (3) designation of single structures of engineering outcomes such as bridges, tunnels, new design techniques, considerable Value Engineering output, and well analyzed Life Cycle Cost Analysis practices. For the evaluation process, NSBP program of USA and/or Sustainable City Award program of Korea would be recommended. An administrative scheme and integrated funding process for the new road projects are also suggested based on evaluation of tasks of each team or division of Korea Ministry of Construction and Transportation.

The input-oriented project promotion system private participation in infrastructure projects currently in use in Korea has encountered difficulties in securing the primary benefits of private sector creativity problem solving and inflow of private capital. As such, the performance (or output)-oriented procurement process implemented in England and other developed countries should be evaluated for introduction. In Korea, private participation projects are currently identified as either solicited or unsolicited projects, each with different promotional procedures, the problem with these procedures is that competition is not pre-activated, the private sectors creativity is under utilized, and the rationality of project evaluations is inconsistent. Korea should, in order to raise the level of private sector creativity and efficiency, go beyond the currently applied Input Specification project promotion system to a Performance-oriented system similar to those implemented in England and other countries. To achieve this, we mate several proposals for the introduction of the performance-oriented system. We divide the main features of our proposals into three categories, including a reformed concessionaire selection system, a performance orientation in preparation of the concession agreement, and a performance orientation in contract management, and discuss each. 1'his study describes performance-oriented promotion systems in an output-focused way As this is an initial study on the introduction of performance orientation in private participation, various key points and proposals were identified. However, in the future, detailed research in technical fields and systems, legal research, and practical projects will be needed for implementation

In spite of various approaching method to satisfy with the owner's requirements in schematic design phase, it is insufficient to evaluate intermediate process of design arithmetically with participating in design process. So the numerous changes of design after completion of design development cause a lot of loss to the design company. The designer arranges owner's requirements to prevent from this loss at the initial stage of schematic design phase systematically and lets owner and stakeholder to evaluate the value of schematic design to satisfy with owner's and stakeholder's requirements. If the evaluated value for schematic design is above a definite value index, the next design phase should be advanced. By this method, the design company can reduce the additional expenses remarkably by preventing with re-design which is occurred by not reflecting owner's intention or by changing owner's intention. Also the designer have the owner to evaluate the result of design and construction. The designer let the owner know whether the owner's requirement should well have been reflected on drawing or not. There is a strong point to be able to minimize the criticism which can be occurred after completion of construction by evaluating for owner's satisfactory degree and by having owner and designer confirm the result of design and construction arithmetically. This paper presents that the loss of design company can be minimized by going over at next step if the value is over a definite value index after evaluating value for each design from design process.

The 'Woencheongang-Bonpuri' is one of the shamanistic myths in Cheju Island. That is a history of ancestor God of the 'Woencheongang'. This myth contains a shaman's initiation. And we can find important archetypal images in it. There are a child, old wise woman, book, water, tree, snake, Yakwangju which is a gem that emits light in the dark, dragon, hierogamy, goddess, time, etc. I've tried to interpret these images through the method of amplification from the perspective of analytical psychology. A heroine of this shamanistic myth is 'Ohnuri' that means 'today'. When she came out from the earth, she was a 'abandoned child' which is a 'hero-motif' in the fairytale and also a theme of individuation process in the analytical psychology. In the mean time, she grew up with helps of the nature, crane, and 'Yakwangju'. One day, she was found in the field by the people. They gave her a name of 'Ohnuri' and one day, an old wise woman told her how to go to her parents. On her way to the 'Woencheongang' where her parents regulate four seasons, she had met many characters which were in stuck. They told willingly Ohnuri a way to go to the 'Woencheongang'. Instead, they wanted to get solutions of their difficult problems. Finally, she met her parents in the 'Woencheongang' with joy and they taught her how to solve problems. Therefore, all characters in this myth could go on their own individuation process fortunately with help of the Whoencheongang's wisdom. In the meanwhile, Ohnuri got Lotus and Yakwangju and then she transformed to the goddess of the highest of the heavenly gods. Then she had helped people who get in trouble. In this way, the 'Woencheon-Bonpuri' was psychologically interpreted from aspect of analytical psychology.

With the increased awareness of energy consumption as well as the environmental impact of building operations, architects, designers and planners are required to place more consideration on sustainability and energy performance of the building. To ensure most of those considerations are reflected in the building performance, critical design decisions should be made by key stakeholders early during the design development stage. The application of BIM during building energy simulations has profoundly improved the energy analysis process and thus this approach has gained momentum. However, despite rapid advances in BIM-based processes, the question still remains how ordinary building stakeholders can perform energy performance analysis, which has previously been conducted predominantly by professionals, to maximize energy efficient building performance. To address this issue, we identified two leading building performance analysis software programs, Energy Plus and IES (IES ), and compared their effectiveness and suitability as BIM-based energy simulation tools. To facilitate this study, we examined a case study on Building Performance Model (BPM) of a single story building with one door, multiple windows on each wall, a slab and a roof. We focused particularly on building energy performance by differing building orientation and window sizes and compared how effectively these two software programs analyzed the performance. We also looked at typical decision-making processes implementing building energy simulation program during the early design stages in the U.S. Finally, conclusions were drawn as to how to conduct BIM-based building energy performance evaluations more efficiently. Suggestions for further avenues of research are also made.

Objective : The objective of this study is to verify the characteristics of acupuncture methods of Joseon Dynasty by looking into the relationship between five viscera diagnosis and acupuncture methods. Material & Method : In the process, I've reviewed the relationship between meridian/exterior and viscera/bowels, along with a thorough comparison of the academic tendency in acupuncture of Ming-China, Qing-China and Joseon. Result & Conclusion : The two fields of meridian and exterior, and viscera and bowels had been theoretically merged, and based upon that, foundation methods applying the five viscera diagnosis were designed. Joseon acupuncture exceeded the existing concept of viscera which simply related itself to the exterior meridian and exterior by integrating the concepts from the visceral manifestation theory. With this, large proportions of medicine related to the visceral manifestation theory were invited into acupuncture, expanding therapeutic boundaries for acupuncture treatment. A historical review on medical texts starts from the Hyangyakjipseongbang("鄕藥集成方") which familiarized the public with mainstream acupuncture knowledge up until the Song dynasty, followed by Uibangyuchwi("醫方類聚"), which sparked up interest on the acupuncture methods based on viscera and bowels. Donguibogam("東醫寶鑑") organized the medical theories up until then, building a foundation upon which viscera/bowel-based acupuncture was able to develop further. In Chimgugyeongheombang("鍼灸經驗方"), viscera/bowel-based acupuncture methods started to blossom, integrating the meridian and exterior theory with the viscera manifestation theory, which in turn provided various methods through five viscera diagnosis. In the Saamdoin acupuncture method(舍岩道人鍼法), diagnostic criteria moved on to the five viscera diagnosis, and new methods resulting from the inter-complimentary and inter-prohibiting relationships between the five phases were introduced, opening a new world of acupuncture.

The rapid growth of information technology and mobile service platforms, i.e., internet, google, and facebook, etc. has led the abundance of data. Due to this environment, the world is now facing a revolution in the process that data is searched, collected, stored, and shared. Abundance of data gives us several opportunities to knowledge discovery and data mining techniques. In recent years, data mining methods as a solution to discovery and extraction of available knowledge in database has been more popular in e-commerce service fields such as, in particular, movie recommendation. However, most of the classification approaches for predicting the movie popularity have used only several types of information of the movie such as actor, director, rating score, language and countries etc. In this study, we propose a classification-based support vector machine (SVM) model for predicting the movie popularity based on movie's genre data and social network data. Social network analysis (SNA) is used for improving the classification accuracy. This study builds the movies' network (one mode network) based on initial data which is a two mode network as user-to-movie network. For the proposed method we computed degree centrality, betweenness centrality, closeness centrality, and eigenvector centrality as centrality measures in movie's network. Those four centrality values and movies' genre data were used to classify the movie popularity in this study. The logistic regression, neural network, $na{\ddot{i}}ve$ Bayes classifier, and decision tree as benchmarking models for movie popularity classification were also used for comparison with the performance of our proposed model. To assess the classifier's performance accuracy this study used MovieLens data as an open database. Our empirical results indicate that our proposed model with movie's genre and centrality data has by approximately 0% higher accuracy than other classification models with only movie's genre data. The implications of our results show that our proposed model can be used for improving movie popularity classification accuracy.

Recently, many researchers have found that the speaker recognition rate is high when they perform the speaker recognition using statistical processing method of orthogonal parameter, which are derived from the analysis of speech signal and contain much of the speaker's identity. This method, however, has problems caused by vocalization speed or time varying feature of speed. Thus, to solve these problems, this paper proposes two methods of speaker recognition which combine DTW algorithm with the method using orthogonal parameters extracted from $Karthumem-Lo\'{e}ve$ Transform method which applies orthogonal parameters as feature vector to ETW algorithm and the other is the method which applies orthogonal parameters to the optimal path. In addition, we compare speaker recognition rate obtained from the proposed two method with that from the conventional method of statistical process of orthogonal parameters. Orthogonal parameters used in this paper are derived from both linear prediction coefficients and partial correlation coefficients of speech signal.

In injection molding process, the appearance quality issue occurs in most injection molded article. One of thermal designs for the mold was performed by increasing the cavity wall temperature with being as uniform as possible in any position. On the basis of the practical evaluation, the cavity wall temperature and finishing machined cavity surface under the optimum processing conditions are the most significant factors to avoid the appearance issue on the plastic part for a good cosmetic quality. Also, the wrong choice of gate type and location can have a considerable effect on the quality of a molded part and it's so important to keep the correct runner balance from each cavity. We've proposed the education training model of the practical tool technology course for the field oriented education to improve practical tool technology ability and optimized tooling design for injection molding quality which can be performed at the workplace substantially.

If a brief direction and plan for a remodeling project are decided, it may moves to a concrete design step of which to select the most suitable alternative out of applicable compounding devices to reveal dynamic drifting performance. However, the volume of knowledge baseed utility which can refer to systematic evaluation regarding remodeling element technology and the accumulation of realistic cases are not only sufficient, but also short including its system for expression and consistency. Therefore, it may necessary to deliver the main frame which make enables the Owner, designer and builder to get performance technology for applying advanced remodeling element and knowledge based utility. There is a necessity to provide an information with latest made by virtue of modeling in the 3D/4D based on construction-based knowledge etc. which we can use for life cycle of a project, as a prominent way of knowledge based utility. Then, it is sure that remodeling can become more activative by sharing of knowledge based utility formed in electronic 3D/4D which is a systematic and expressed consistently to a performance and applicability in preservation of savings. It is expected for modeling of the 3D/4D in knowledge based utility enables to verify the practicability of each technology on effective application, and the use of technology might be spread widely due its obvious and oriented expressions. Further, this knowledge based utility formed in electronic 3D/4D may applicable for VE process in addition to remodeling design fields.
