Balhae was an ancient Korean kingdom that existed almost 1,300 years ago. It was a dynamic time in the Korean history when the national strength was building up in terms of politics, economy and culture, thereby called as "Haedongseongguk, the powerhouse in the East". Balhae had dominated parts of Manchuria and the northern part of the Korean peninsula between the late 7th century and the 10th century, occupying the center stage of the northern Korean history. It serves as a window to the East Asia in the present as well as in the past. Yet, due to its geography spanning from the North Korea to Kilin Province of China to part of Heilongjiang Province and to the Littoral Province of Siberia, Balhae has been the center of historical disputes among neighboring countries that insist it is part of each of their own history. China argues that it was a prefecture of the Tang Dynasty, established by the Mohe, not a successor to Goguryeo, which is a China-oriented viewpoint of history. In addition, Russia recognizes Balhae as their first-ever medieval feudal state since the Littoral Province is now under their sovereignty. Therefore, the restoration of Balhae history is in line with the veritable establishment of the ancient Korean history. For this, it is necessary to embrace inter-disciplinary achievements and to continue efforts to adopt them rather than to blame the shortage of historical documents and the difficulty of the excavation of relics. If fashion is "a visual symbol" of our society, beauty culture serve as a mirror to reflect our civilization and culture directly or indirectly. Still, it is not easy to draw similarities by analyzing and comparing the attributes of various cultures and civilizations party because the essence of culture lies in diversity. Nevertheless, it is believed that cultural liaison as well as geographical liaison can be a medium to compensate for the limits of the foreign exchange history of Southeast Asia in proving the relationship between Goguryeo and Balhae, by examining and speculating beauty culture that reflect their period. It was confirmed by various documents regarding Goguryeo out of relics, historical sites and documents. Mural paintings showed how the people of Balhae wore and accessorized themselves. They also allowed us to speculate their way of living. As the contemporary historians can assert that Balhae is part of the Korean history thanks to the realism scholars in the late Joseon Dynasty, who rediscovered the Balhae history and conducted practical researches, it is expected that researchers who study beauty culture contribute to completing the restoration of the Balhae history by thoroughly examining our history, costume and beauty culture.

The reliability problems of flip chip packages subjected to temperature change during the packaging process mainly occur due to mismatches in the coefficients of thermal expansion as well as features with time-dependent material properties. Resin molding compounds like glass fiber reinforced epoxy composites used as the dielectric layer in printed circuit boards (PCB) strongly exhibit viscoelastic behavior, which causes their Young's moduli to not only be temperature-dependent but also time-dependent. In this study, the stress relaxation and creep tests were used to characterize the viscoelastic properties of the glass fiber reinforced epoxy composite. Using the viscoelastic properties, finite element analysis (FEA) was employed to simulate thermal loading in the pre-baking process and predict thermal warpage. Furthermore, the effect of viscoelastic features for the major polymeric material on the dielectric layer in the PCB (the glass fiber reinforced epoxy composite) was investigated using FEA.

Recently, the National Emergency Management Agency of Korea has been operating the National Disaster Management System. Nevertheless, there are numerous difficulties in systematic controlling the steep slope DB promptly, because the system's functions in input and control for steep slope information are merely simple. Futhermore, the hazard degrees of steep slope lands nowadays have risen suddenly in accordance with the increase rate of large scale landslides such as the landslide cases of Umyeonmountain, Chuncheon province and others or sever rain storm cases. these lead to rapid increases in frequencies of nature disasters nationally. therefore, it is needed to develop the GIS-based integrated management system for steep slope information in order to manage disasters in advance or high-degree control. This study shows the national GIS-based integrated management system to prevent the disasters that caused by steep slope lands. The integrated management system developed in this study consists of surface information input modules, realtime DB liaison modules of integrated underground information, V-world background map-based GIS, integrated management system for steep slope information user modules, realtime liaison interface modules designed for utilizing steep slope information. Also, tests about stability of data storage, system stability and consistency of processing speed were performed.

The purpose of the study was to explore what kind of intervention might help foster parents decide to continue engaging in foster care. As foster care services are still in the early stages of development, lacking systematic support systems as well as full understanding of the roles of foster parents and foster care agencies, it is important to recruit, select, and train as many foster parents as possible. Utilizing the Foster Parent Role Perception scale developed by Le Prohn, the author first conceptualized foster parent roles or foster care agency roles; then explored what kind of effects the resource level or the role perception of the foster parents have on the decisions to continue doing foster care. The results showed that the foster parents perceived 'supporting the internal system of the foster child' and 'supporting the external system of the foster child' as the roles of foster parents, whereas 'fortifying the foster care system' and 'maintaining liaison with birth parents' were the roles of foster care agencies. It was also found that foster parents' strong role perception, higher levels of satisfaction towards education on the part of foster parents, and the number of children from the previous marriage had statistically significant positive effects on the decisions to continue foster care. The author argues that clear definitions of roles are needed for both foster parents and foster care agencies. Finally, the role of foster care agencies needs to be strengthened and supported.

For a field of research to be an independent area of study, there must be a common paradigm that is shared by the members of the community. In addition. for establishment of identity in a study, several relating scientific communities should actively study and research, which lead to a new paradigm. Efforts to accomplish this purpose are found in Politics, Economics, and Psychology. Yet, the field of Fire Service Science have not yield these results which include active scientific communities, scholars and experts who research on the subject and exchange their expertises. New paradigm for the field is not established yet. Therefore, this research probes the origins of these problems and suggests a proper scientific paradigm and direction for establishment of identity of Fire Service Science in Korea's ambiance.

In this paper, a method for prediction of spread is proposed to design proper roll profile taking into account spread in shape rolling of angle bar. The effect of the process variables on spread, such as draught ratio, bending angle and aspect ratio, is analyzed by FE-analysis and response surface method (RSM). Roll profiles for equal angle bar are designed with the spread predicted by the regression equation. Effectiveness of the designed roll profiles are verified by FE-analysis in which the flange length, strain distribution, mean strain and roll torque are compared with those by Geuze. Finally, the proposed method is applied to the design of roll profile for unequal angle bar. As a result, the final product can be obtained within the allowable tolerance of ${\pm}0.5mm$ in length. Therefore, it is found that the prediction of spread can improve the efficiency of design roll profile in shape rolling of angle bar.

Due to the development of electric and hybrid vehicles, the trend has changed from hydraulic power steering system to electric power steering system (EPS). In this paper, design parameters are deduced through the structural analysis based on the finite element analysis for the intermediate shaft of the EPS on the market. By analyzing the design parameters, the structure design is improved to support the required high torque on the EPS. The numerical analysis is performed to obtain the improved design of the intermediate shaft model and the analysis results are compared with the existing model. It is noted through this numerical approach that the improved design of the intermediate shaft can be acquired the structural safety and high stiffness than existing model.

Cloud computing evolve as a cost effective business model for IT companies to focus on their core business without perturbing on infrastructure related issues. Hence, major IT firms and Small & Medium Enterprises (SME) are adopting cloud services on rental basis from cloud providers. Cloud Service level agreements (SLA) act as a key liaison between consumers and providers on renting Anything as a Service (AaaS). Design of such an agreement must aim for greater profit to providers as well as assured availability of services to consumers. However in reality, cloud SLA is not satisfying the parties involved because of its inherent complex nature and issues. Also currently most of the agreements are unilateral to favour the provider. This study focuses on comprehensive, 360-degree survey on different aspects of the cloud service agreements. We detailed the life cycle of SLA based on negotiation, different types of SLA, current standards, languages & characteristics, metrics and issues involved in it. This study will help the cloud actors to understand and evaluate the agreements and to make firm decision on negotiation. The need for standardized, bilateral, semantic SLA has also been proposed.

With the rapid growth of geriatric population, geriatric psychiatric consultation has come to play a more important role in recent years. It is necessary to find out characteristics of psychiatric consultation-liaison in elderly and applicate practical guideline of consultation in medical setting. Management of medically ill elderly in psychiatric consultation requires different guideline from that of other age group patient. Because aging and each organ-specific diseases change the pharmacokinetics of psychotropic drugs variably. These pharmacokinetic changes should be considered in psychosomatic treatment in medically ill elderly. The relatively low consultation rates for psychiatric disorders in the elderly indicate that research is needed into factors that both prevent and facilitate elderly patients with psychological symptoms from consulting their general practitioners.

We present a statistical analysis of Korean phonological variations using automatic generation of phonetic transcription. We have constructed the automatic generation system of Korean pronunciation variants by applying rules modeling obligatory and optional phonemic changes and allophonic changes. These rules are derived from knowledge-based morphophonological analysis and government standard pronunciation rules. This system is optimized for continuous speech recognition by generating phonetic transcriptions for training and constructing a pronunciation dictionary for recognition. In this paper, we describe Korean phonological variations by analyzing the statistics of phonemic change rule applications for the 60,000 sentences in the Samsung PBS(Phonetic Balanced Sentence) Speech DB. Our results show that the most frequently happening obligatory phonemic variations are in the order of liaison, tensification, aspirationalization, and nasalization of obstruent, and that the most frequently happening optional phonemic variations are in the order of initial consonant h-deletion, insertion of final consonant with the same place of articulation as the next consonants, and deletion of final consonant with the same place of articulation as the next consonants. These statistics can be used for improving the performance of speech recognition systems.
