  • While the current consensus view holds that galaxy mergers are commonplace, it is sometimes speculated that Globular Clusters (GCs) may also have undergone merging events, possibly resulting in massive objects with a strong metallicity spread such as Omega Centauri. Galaxies are mostly far, unresolved systems whose mergers are most likely wet, resulting in observational as well as modeling difficulties, but GCs are resolved into stars that can be used as discrete dynamical tracers, and their mergers might have been dry, therefore easily simulated with an N-body code. It is however difficult to determine the observational parameters best suited to reveal a history of merging based on the positions and kinematics of GC stars, if evidence of merging is at all observable. To overcome this difficulty, we investigate the applicability of supervised and unsupervised machine learning to the automatic reconstruction of the dynamical history of a stellar system. In particular we test whether statistical clustering methods can classify simulated systems into monolithic versus merger products. We run direct N-body simulations of two identical King-model clusters undergoing a head-on collision resulting in a merged system, and other simulations of isolated King models with the same total number of particles as the merged system. After several relaxation times elapse, we extract a sample of snapshots of the sky-projected positions of particles from each simulation at different dynamical times, and we run a variety of clustering and classification algorithms to classify the snapshots into two subsets in a relevant feature space.

  • As a dental technician, the aim of the present study on maxillofacial prosthesis was to research its relation with dental technology and further development aspects by looking into its history, kinds, production materials and process. Dental technicians are to expect a great potential to work as maxillofacial prosthetist if having an interest in education of maxillofacial prosthesis field, and developing and operating the education process by expanding the range of dental technology. This article is to present overall history of maxillofacial prosthesis and some background information on the materials which have been used from the past. The maxillofacial field plays essential functions of mastication and speech, as well as performs appearance, which evokes good or bad feelings as an instant and instinctive response. The use of maxillofacial prostheses is not merely the replacement of a missing part of the face, resulted from injuries, but a rehabilitation process to help individuals come back to society. Rehabilitation includes both patient's physical and psychological recovery, such as self-esteem and selfconfidence. There has been a rapid development in application potentials of maxillofacial prosthesis technology which include implant, which can penetrate skin, and new materials. In order to produce maxillofacial prosthesis, general procedures of maxillofacial laboratory work should be understood first. Maxillofacial prosthesis and the dental prosthesis have many similarities in its academic perspective and originality. Maxillofacial prosthesis should be added into the curriculum for dental technology to achieve co-enhancement of the two fields.

  • Purpose: The purpose of this study was to analyze the prevalence of allergic disease among elementary school students in rural and urban areas. Methods: In this study, 1,513 elementary students (1,163 in urban areas, 350 in rural areas) were surveyed. Data were analyzed using frequency, percentage of allergic symptoms and $X^2$ test was used to identify differences in the prevalence of allergic symptoms between urban and rural area students. The SAS program was used in the data analysis. Results: There were significant differences in the prevalence of allergic disease according to whether there was a family member with a prior history of allergy symptoms. 48.7% of surveyed students (49.4% in urban, 46.3% in rural) had allergic symptoms. Allergic rhinitis was the most frequent allergic symptom in both urban and rural students. Conclusion: These results suggest that there is a need to prevent and manage allergies among elementary students. The family history should be considered an important factor when a program for allergy prevention and management is developed. Interventions are needed in both areas, especially for students with allergic rhinitis.

  • Purpose: The purpose of this study was to compare the spiritual well-being and quality of life between hospital and home hospice patients. Methods: A total of 116 patients from 4 hospice hospitals in D city and P city participated in this study from January to April 2012. To measure spiritual well-being, an instrument developed by Paloutzian and Ellison (1982) and revised by Park (2005) was used. To measure quality of life, an instrument developed by Cho (1993) and revised by Sun (2003) was used. The data were analyzed by using descriptive statistics, t-test, $x^2$-test, and ANCOVA. Results: Spiritual well-being and quality of life were higher in home hospice patients than in hospital hospice patients, but they were not statistically significant. Higher education and having religion were significantly related to higher spiritual well-being in both groups. Having religion and pain history for the past one week were significantly related to higher quality of life in both groups. Conclusion: For hospice patients, participation in religious activities needs to be encouraged to improve their spiritual well-being and quality of life. Assessing the hospice patients' pain history with close observation and managing the pain are suggested.

  • The damping effect of a Concrete-filled Rectangular Steel Tube (CRST) frame structure is studied in this paper. Viscous dampers are employed to insure the function of the building especially subjected to earthquakes, for some of the main vertical elements of the building are not continuous. The shaking table test of a 1:15 scale model was conducted under different earthquake excitations to recognize the seismic behavior of this building. And the vibration damping effect was also investigated by the shaking table test and the simulation analysis. The nonlinear time-history analysis of the shaking table test model was carried out by the finite element analysis program CANNY. The simulation model was constructed in accordance with the tested one and was analyzed under the same loading condition and the simulation effect was then validated by the tested results. Further more, the simulation analysis of the prototype structure was carried out by the same procedure. Both the simulated and tested results indicate that there are no obvious weak stories on the damping equipped structure, and the dampers can provide the probability of an irregular CRST frame structure to meet the requirements of the design code on energy dissipation and deformation limitation.

  • There has been much recent interest and research into meridian theory. Two main types of meridian theory generally identified: the forward heart meridian system and the circulative meridian system. Little attention has been paid to how these types of alignments operate in the Zhenjiuzishengjing (鍼灸資生經) and the Shisijingfahui (十四經發揮). This paper reviews the meridian systems of these two texts and compares them to the meridian and collateral theory found in the Huangdineijing (黃帝內經). It compares the meridian point systems of the various texts and their alignment by location and meridian to shows how the meridian-based method used in the Zhenjiuzishengjing is similar to the forward heart meridian system found in the "Benshu" (本輸) section of the Neijing while the method used in the Shisijingfahui is close to circulative meridian system found in the "Jingmai" (經脈) section of the Neijing.

  • Gliosarcoma (GS), known as variant of glioblastoma multiforme, is aggressive and very rare primary central nervous system malignant neoplasm. They are usually located in the supratentorial area with possible direct dural invasion or only reactive dural thickening. However, in this case, GS was located in lateral side of left posterior cranial fossa. A 78-year-old man was admitted to our hospital with 3 month history of continuous dizziness and gait disturbance without past medical history. A gadolinium-enhanced MRI demonstrated $5.6{\times}4.8{\times}3.2cm$ sized mass lesion in left posterior cranial fossa, heterogeneously enhanced. The patient underwent left retrosigmoid craniotomy with navigation system. The tumor was combined with 2 components, whitish firm mass and gray colored soft & suckable mass. On pathologic report, the final diagnosis was GS of WHO grade IV. In spite of successful gross total resection of tumor, we were no longer able to treat because of the patient's rejection of adjuvant treatment. The patient survived for nine months without receiving any special treatment from the hospital.

  • The Joseon royal family considered the act of burying the placenta very important for various reasons. Accordingly, they developed their own ritual culture of burying the placenta based on the geomancy(Pungsu). In 1661, The King Sukjong's placenta chamber was built in Gong-ju, and later stone objects were added in 1683. Since its establishment, the King Sukjong's placenta chamer have been continuously managed by the Joseon royal family, but During the Japanese colonial period, the placenta chamber was partially destroyed, and now only some stone objects remain in the original site. This study aims to estimate the original style and structure of King Sukjong's placenta chamber by focusing on the stone objects which were discovered through recent field surveys. In addition to that, the stylistic review of Joseon Dynasty's royal placenta chamber was conducted to secure a literary data basis and acquired data were comprehensively analyzed. As a result, Some of the original style and structure of King Sukjong's placenta chamber could be confirmed. The results of this study are expected to help restore the authenticity of the royal placenta chamber damaged in japanese colonial period, and are expected to be a good example in the research methodology of historical evidence of other damaged royal placenta chambers.
