Scientific investigation of cultural heritage can provide important information to understand the context of the object. To know the characteristics of the material is also an essential part of objects management and conservation. However, the identification and characterization of organic dyes used in archaeological and historical textiles are often limited by the restrictions in sampling. To cope with the difficulties, applications of high-performance techniques of surface analysis, such as Time of Flight-Secondary Ion Mass Spectra (TOF-SIMS) could be considered as a non or micro-destructive option. This study aims to examine the applicability of TOF-SIMS analysis to the detection of organic dyes from historical textiles. A group of silk fabrics dyed with vegetable dyes were artificially photo-aged to different degrees and analyzed with TOF-SIMS. Molecular and fragment ions from indigo were successfully detected from the aged samples; however, only some fragment ions were observed from gardenia and safflower dyed fabrics. Further studies with actual historical samples with extended examination scope would be necessary to assess the validity of this technique.

본 연구의 목적은 후기노인들의 삶에 나타난 일제강점기와 6.25전쟁에 대한 '개인적인 역사경험'이 어떠한 '현재성'이 있는지 생애사적 맥락에서 '재구성'하는 데에 있다. 이를 위해 Sch$\ddot{u}$tze의 자료수집 방법에 따라 실시한 '생애사적-내러티브 인터뷰' 9개를 Rosenthal의 '내러티브식-생애사 인터뷰 분석'방법에 따라 분석하였다. 그 결과, 개인적인 역사경험의 현재성은 주로 경험방식에 따른 차이를 보임을 알 수 있었다. 즉 '친일경험'으로서의 일제강점기에 대한 직접적인 역사경험과 '국군생활'로서의 6.25전쟁에 대한 직접적인 역사경험은 '개별화된 현재성'이 있는 반면, '남편의 역사적 죽음'으로 표출된 일제강점기나 6.25전쟁에 대한 간접적인 역사경험은 '잠재된 현재성'이 있는 것으로 나타났다. 이러한 연구결과에 근거해 개인적인 역사경험의 현재성에 대한 '이해'를 바탕으로 하는 노인복지실천을 위한 제언을 하였다.

In the past decades, effect of near field earthquake on the historical monuments has attracted the attention of researchers. So, many analyses in this regard have been presented. Tunnels as vital arteries play an important role in management after the earthquake crisis. However, digging tunnels and seismic effects of earthquake on the historical monuments have always been a challenge between engineers and historical supporters. So, in a case study, effect of near field earthquake on the historical monument was investigated. For this research, Finite Element Analysis (FEM) in soil environment and soil-structure interaction was used. In Plaxis 2D software, different accelerograms of near field earthquake were applied to the geometric definition. Analysis validations were performed based on the previous numerical studies. Creating a nonlinear relationship with space parameter, time, angular and numerical model outputs was of practical and critical importance. Hence, artificial Neural Network (ANN) was used and two linear layers and Tansig function were considered. Accuracy of the results was approved by the appropriate statistical test. Results of the study showed that buildings near and far from the tunnel had a special seismic behavior. Scattering of seismic waves on the underground tunnels on the adjacent buildings was influenced by their distance from the tunnel. Finally, a static test expressed optimal convergence of neural network and Plaxis.

For three years, from 2014 to 2016, in dental history class, 263 3rd grade students, attending postgraduate dental school had reviewed current problems of the dentistry and dental care system by adopting historical thinking, in forms of essays, editorials, and papers, The purpose of this study is to know whether writing has educational benefits on students. Analysis of the writings and Student course evaluation showed that it is beneficial. All of the students agreed on submitting a qualitative study project instead of taking midterms on 2016. The approval ratio has increased over the years, on 2014 being 82%, on 2015 being 98%, on 2016 being 100%. For that reason, it is not an assertion to deduce that the students have experienced benefits while developing their genuine thoughts on the current status or problems, exploring what their role is, and what they will face. The chronological thinking had been used throughout the researches to identify what Dentistry and Dentist is. Dentistry have encompassed knowledges of natural sciences, humanities and other fields when needed to perfect itself. In doing so, Dentist achieved independence from doctor or other cooperatives. Research on Korean Dental care system has involved in historical thinking, including historical analysis, inquisition, and historical imagination, insight. etc. If the in-depth evaluation consisting of history and writing is sustained, it would be very effective teaching method.

Fire was and remains a great threat to historic buildings of wood. This threat is omnipresent and often results to irreparable property losses especially cultural heritages. Fire of historic buildings continues to increase every year. The purpose of this study is to preserve a life safety, historical heritage and architectural & cultural values by pursuing for fire safety in the historical buildings. This study shall employ two research methods: a literature review and field survey methods. The literature review shall focus on the observations of characteristics noted in fire codes. The field survey shall cover a heat analysis and fire protection equipment. A method is proposed to investigate fire codes related historical building, reported fire history Fire Codes and Regulations for modern buildings are not always applicable on the historic buildings. Old buildings, and some new buildings with architectural, historical or cultural importance may have values which cannot be measured on a monetary scale. Their protection against the damage caused by fire is considered to be one of the basic moral duties of society. It is strongly recommended, therefore, legislation for fire safety in historical buildings must be extended to a complementary relationship with 'active' fire protection measures, to provide safety in real historical building in real fire situations. The development and application of performance based Codes and the Fire Safety Engineering approach seems to be a rather reasonable and effective way to deal with this historical buildings.

In general, the interaction conditions between the discrete stones are not taken into account by structural engineers during the modeling and analyzing of historical stone bridges. However, many structural damages in the stone bridges occur due to ignoring the interaction conditions between discrete stones. In this study, it is aimed to examine the seismic behavior of a historical stone bridge by considering the interaction stiffness parameters between stone elements. For this purpose, Tokatli historical stone arch bridge was built in 1179 in Karabük-Turkey, is chosen for three-dimensional (3D) seismic analyses. Firstly, the 3D finite-difference model of the Tokatli stone bridge is created using the FLAC3D software. During the modeling processes, the Burger-Creep material model which was not used to examine the seismic behavior of historical stone bridges in the past is utilized. Furthermore, the free-field and quiet non-reflecting boundary conditions are defined to the lateral and bottom boundaries of the bridge. Thanks to these boundary conditions, earthquake waves do not reflect in the 3D model. After each stone element is modeled separately, stiffness elements are defined between the stone elements. Three situations of the stiffness elements are considered in the seismic analyses; a) for only normal direction b) for only shear direction c) for both normal and shear directions. The earthquake analyses of the bridge are performed for these three different situations of the bridge. The far-fault and near-fault conditions of 1989 Loma Prieta earthquake are taken into account during the earthquake analyses. According to the seismic analysis results, the directions of the stiffness parameters seriously changed the earthquake behavior of the Tokatli bridge. Moreover, the most critical stiffness parameter is determined for seismic analyses of historical stone arch bridges.
