Government agencies have many difficulties for the information system development and operation. One of the difficulties is a budget estimation. Each government agency suggests individually different estimation for the personnel expenses and IT infrastructure adoption costs in the same field of informatization promotions. The other one is the operation costs are increased exponentially in every year[42, 51]. Those difficulties make government agencies can not help adopting SaaS. In fact, most of IT consulting company and government agencies already recognized a variety of SaaS advantages. The most typical SaaS's advantages are cost reduction, Software rapid development and deployment. However, once government agencies decide to adopt SaaS, they can not avoid many problems and difficulties. There is no information in a detailed item in a budget. In those kinds of situation, there is no choice whether government agencies accept SaaS provider's suggesting adoption costs or not. Thus, we provide a sheet of SaaS adoption cost estimation to government agencies. To know the cost factors, this study uses TCO(Total Cost of Ownership)'s criteria. To give a management point, this study uses Gartner's Application development Life Cycle. In this study, the integration check framework which is SaaS adoption cost estimation makes government agencies possible to establish a adequate budget.

We are in search for many method at 21th century thinking about the environment internationally. One is among them low carbon green city. Consequently this dissertation put a system solar energy key point of low carbon green city and purpose of low carbon green city Besides system and technique about the solar energy best practices try to do the investigation analysis. It's important of low carbon green city's environmental friendly system such as solar heat system, solar power generation, ecological greening, All these systems are connected each other and organize low carbon green city. A solar energy system uses pure energy of the situation directly most among the environmental friendly system. Energy saving and environment-friendly city in the world must do not a choice. However, recognition conversion and infrastructure of the Korea still has not come true. But South Korea and the international best practices is not the same system. But plan to solar city, the concept of green city in Cheongju, Deagu local government. And many meetings are in progress.

This study aims at exploring Korean mothers' beliefs on the development of emotion of their children. In specific, sensitivity and maternal reactions to their children's both negative and positive emotion expressions were explored. Further, associations among maternal sensitivity, maternal reactions and child emotion regulation were examined. A total of 100 Korean mothers whose children were between 6 and 7 years old participated in the study. In order to assess mothers' beliefs about sensitivity, vignettes in a forced-choice format were presented through individual interviews. Mothers' self reported reactions to their children's negative emotions and positive emotions and mothers' perceptions of children's emotion regulation were assessed using questionnaires. Results revealed that Korean mothers endorsed both proactive and reactive sensitivity. However, their sensitivity differed depending on the situation. Mothers tended to endorse either Emotion Focused or Problem Focused reactions to their children's negative emotions. Mothers reported that they were most likely to restrict their child positive emotional expression with explanation in supportive way followed by invalidating through reprimanding it. Mothers' reported Distress Reactions and Punitive Reactions to children's expression of negative emotion were associated with children's liability whereas Emotion-Focused Reaction and Problem-Focused Reaction were associated with children's functional emotion regulation. The results are discussed within a theoretical framework of socialization of emotions.

Active noise control uses the intentional superposition of acoustic waves to create a destructive interference pattern such that a reduction of the unwanted sound occurs. In active noise control system the choice of a control structure and design of the controller are the main issues of concern. In real acoustic fields there are a vast number of noise sources with time-varying nature and the characteristics of transducers and the geometric set-up of control system are subject to change. Accordingly the control system should be designed to adapt such circumstances so that required level of performance is maintained. In this paper, the adaptive control algorithm for self-tuning adaptive controller is presented for the application in active noise control system. Self-tuning is a direct integration of identification and controller design algorithm in such a manner that the two processes proceed sequentially. The least mean square algorithm was used for the identification schemes and adaptive weighted minimum variance control algorithm was applied for self-tuning controller. Computer simulation results for self-tuning feedback controller are presented. And simulation results was shown to be useful for the situation in which the periodic noise sources act on the acoustic field.

The development of Korea in the Northeast through trade is not a matter of choice as far as national strategy is concerned, but is an important national policy that is a matter of life or death which will determine the future fate of Korea. This thesis will attempt to arrive at a general, tangible plan for the development of Korea in the Northeast centered around trade by examining the change in naval environment at home and abroad, the given economic situation in the Northeast, and the present state of essential port development in Korea-China-Japan. Its objective will be to provide strategies for the development of Busan port confrontation. For the last ten years, China has been growing at a rapid rate. Since a lot of the volume of naval trade is being transferred from Korea to China, we must do everything we can to improve the service and reduce cost. In addition, Japan also is losing international position. Japan's government and the private industry are trying to make Super Core Ports a prominent feature of their port system. If the Busan port system is to remain competitive, these aspects of the Japanese port system must be kept in mind to prevent trade from going to other ports with more competitive systems.

In the midfacial fracture, the orbital region presents many additional complication unique to the orbit. Among them are ectropion, entropion, lid ptosis, injury to the lacrimal apparatus, diplopia or the late development of enophthalmos. The residual problem confronting the surgen is usually enophthalmos or diplopia. Enophthalmos becomes cosmetically obvious at 3mm and if more severe it can interfere with vision from obstruction by the orbital rim. In this clinical situation, many patients prefer the simpler intraorbital volume expansion to the more complex orbital osteotomy. In general, except in mild cases of enophthalmos, the procedure of choice is osteotomy and repositioning for zygoma fracture and volume augmentation for blow-out fracture. Late treatment is performed by volume augmentation based on the CT findings behind the axis of the globe. Inferiorly placed grafts elevate the globe, posterior superior grafts move the globe anterior and medially positioned grafts push the globe laterally. In this two cases, the patients who has stable orbitozygomatic rim, the use of calvarial bone grafts more than 3 areas around intraorbital content, we corrected late enophthalmos combined with diplopia. As result, the first patient had 2mm advance in exophthalmometric check with improvement of the diplopia gradually. The second patient had 1.5mm advance with correction of vertical ocular dystopia and cosmetically good results respectively.

A 39-year-old male was admitted to Dept. of Thoracic Cardiovasc. Surgery, Korea University Hospital with the chief complaints of progressively enlarged mass on right upper lung which revealed on routine chest P-A since 4 Years ago. Chest PA and tomography revealed well circumscribed huge mass of 7cm. in diameter without invasion on bronchus. so, right upper lobectomy was performed under impression of lung cancer. Postoperative pathologic examination revealed pulmonary blastoma. Pulmonary blastoma is accepted as a distinctive neoplasm recently. One case of typical pulmonary blastoma is reported, and the previous literature is reviewed. There are no specific clinical or radiologic feature of pulmonary blastoma. The presentation is can be that of any other pulmonary tumor although a peripheral situation is usual and a large size is often attained before detection. Pulmonary blastoma is a mixed tumor with malignant epithelial and connective tissue components with a distinctive resemblance to fetal lung. The treatment of choice is surgical excision but the overall prognosis is poor. There is no evidence of recurrence or metastasis on follow-up study during 6 months period after right upper lobectomy.

This thesis is on the identification pattern for immersion of visual storytelling and studied identification which is psychological action in the visual aspect. Shots which the audience were identified with character's eyes in animation were classified and connection structures of shot and shot were coded through semiological analysis. In shot's coded combination regularly organized, identification patterns which have characteristic meanings were discovered. These patterns which have characteristic meanings can be used by choice following the narrative situation. Therefore identification visual patterns which can be used in real production environment are to be suggested.
