Purpose: Dental implants present several advantages over other tooth replacement options. However, there has been little research on masticatory function in relation to implant treatment. Therefore, the aim of the present study was to evaluate the improvement of masticatory function two weeks after implant restoration. Methods: Masticatory ability was evaluated with the subjective food intake ability (FIA) and objective mixing ability index (MAI) methods. Fifty-four subjects with first and second missing molars completed the study. The subjects were asked to complete a self-reported questionnaire about 30 different food items, and to chew wax samples 10 times both before and two weeks after implant restoration. A total of 108 waxes were analyzed with an image analysis program. Results: Dental implant restoration for lost molar teeth on one side increased the FIA score by 9.0% (P<0.0001). The MAI score also increased, by 14.3% after implant restoration (P<0.0001). Comparison between the good and poor mastication groups, which were subdivided based on the median MAI score before implant restoration, showed that the FIA score of the poor group was enhanced 1.1-fold while its MAI score was enhanced 2.0-fold two weeks after an implant surgery. Conclusions: Using the FIA and MAI assessment methods, this study showed that masticatory function was improved two weeks after implant restoration. In particular, the enhancement of masticatory function by implant restoration was greater in patients with relatively poor initial mastication than in those with good initial mastication.

Objectives: This study aimed to evaluate the interface between a calcium silicate cement (CSC), Biodentine and dental adhesives in terms of sealing ability. Materials and Methods: Microleakage test: 160 standardized class II cavities were prepared on 80 extracted human molars. The cavities were filled with Biodentine and then divided into 2 experimental groups according to the time of restoration: composite resin obturation 15 minutes after Biodentine handling (D0); restoration after 7 days (D7). Each group was then divided into 8 subgroups (n = 5) according to the adhesive system used: etch-and-rinse adhesive (Prime & Bond); self-etch adhesive 2 steps (Optibond XTR and Clearfil SE Bond); self-etch adhesive 1 step (Xeno III, G-aenial Bond, and Clearfil Tri-S Bond); and universal used as etch-and-rinse or self-etch (ScotchBond Universal ER or SE). After thermocycling, the teeth were immersed in a silver nitrate solution, stained, longitudinally sectioned, and the Biodentine/adhesive percolation was quantified. Scanning electron microscopic observations: Biodentine/adhesive interfaces were observed. Results: A tendency towards less microleakage was observed when Biodentine was etched (2.47%) and when restorations were done without delay (D0: 4.31%, D7: 6.78%), but this was not significant. The adhesives containing 10-methacryloyloxydecyl dihydrogen phosphate monomer showed the most stable results at both times studied. All Biodentine/adhesive interfaces were homogeneous and regular. Conclusions: The good sealing of the CSC/adhesive interface is not a function of the system adhesive family used or the cement maturation before restoration. Biodentine can be used as a dentine substitute.

The purpose of this study was to evaluate the adaptability of light-cured glass ionomer cement to cavity walls. Class V cavities were prepared on the labial surfaces of extracted bovine incisor teeth. The cavities were restored with Fuji II as self-cured glass ionomer cement and Fuji II LC, Vitremer as light-cured glass ionomer cement. Fluorescent markers (fluoreceine and rhodamin B) were incorperated into liquid and primer for a better image of microscopic observation. Restored teeth were sectioned by longitudinal and labiolingual direction. The adaptability at the tooth-restoration interface was assessed incisally, axially and cervically by confocal scanning laser microscope. Following results were obtained : 1. Chemical-cured glass iomomer cement restoration showed close adaptation on the all of the cavity walls, but, cracks formed within the cement. 2. Light-cured glass ionomer cement restoration was well adapted to the cavity walls, but showed crack in the cement adjacent to axial dentinal wall. 3. There' was no significant difference in adaptability between two light-cured glass ionomer cement restorations.

Two types of regularization method (singular system and HMP approaches) for generating depth-concentration profiles from angle-resolved XPS data were evaluated. Both approaches showed qualitatively similar results although they employed different numerical algorithms. The application of the regularization method to simulated data demonhstrates its excellent utility for the complex depth profile system . It includes the stable restoration of depth-concentration profiles from the data with considerable random error and the self choice of smoothing parameter that is imperative for the successful application of the regularization method. The self choice of smoothing parameter is based on generalized cross-validation method which lets the data themselves choose the optimal value of the parameter.

This paper is a study of "poetry therapy", a subject now in lively in literary discussion circles. Modern literary text attaches great importance to the readers' response. As such, there is growing interest in the effects of communication brought on by the interaction of participants in a discourse. Poetry, in essence, has therapeutic attributes of treating, through an aesthetic psychology, destruction resulting from the alienation from life and psychological pain of distortion. The rise of the concept of eco-poetry and the capacity for psychological cleansing and adjustment (which restores balance through communication and psychological circulation) is a reflection of new trend in research - approaching the alienation felt by modern people through restoration of sense of life. Although Kim Hyun-seung's life and the road his poetry took was not smooth, he nevertheless was firm in his sustained effort to unify socio-ethical conscience and conscience of faith through the process of spiritual inquiry. The most outstanding aspects of Kim Hyun-seung's aesthetic achievement lie in his contribution toward the therapeutic capacity of modern poetry. Kim Hyun-seung's poetryhas the following effects: 1)The therapeutic capacity of modern poetry, through catharsis at large, does not remain only at the level of cleansing and adjustment. 2)The therapeutic capacity of modern poetry has the function of emptying out the self through more fundamental spiritual awakening and insight. 3)Only then can one truly realize the transcendence of being a true self as well as the balanced inquiry of spirituality which can be described as "emptying out".

Purpose: This study was designed to determine whether General Coordinative Manipulation (GCM) Intervention Models have effects on the balanced restoration of asymmetrical muscles in the extremities. Methods: Fifty-nine healthy subjects (1st hypothesis: n=40, 2nd hypothesis: n=19) participated in studies using the two GCM intervention models. Subjects were studied 2 times a week for 3 weeks. Electromyography (EMG) was used to measure muscle activity, and measurements were performed before and after the application of the each intervention model. Results: Hypothesis 1: GCM Intervention, which coordinates flexion types of muscle contractions of the upper extremity and extension types of muscle contractions of the lower extremity (excluding self-care) is effective for treating shows the treatment in efficiency on more than two 2 of 3 muscles (vastus medialis, gastrocnemius medial, and deltoid middle) and the effects affects on more than 3 types of 4 body types (Vastus medialis, Gastrocnemius medial of Body type III, p<0.05). GCM body type was classified by the relative tilting of right and left scapulars and iliums into four groups. Hypothesis 2: GCM Intervention, which coordinates flexion types of muscle contractions of the lower extremity and extension types of muscle contractions of the upper extremity (excluding self-care) is effective for treating more than two 2 of 3 muscles (vastus medialis, gastrocnemius medial, and deltoid middle) and the effects affects on more than 2 types of 3 body types (p>0.05).

This text discusses trends in the construction of religions since the Meiji Era, using Konkokyo and Restoration Shintoism as examples. The construction of religions is applied here as the process of a deliberate acceptace of religious images as a discourse of "Civilization" endowed with "kyougi" or "Doctrine" and "kyousoku" or "Rules of Instruction." Winding through a meandering path, these constructed religions do not take precedence over "Jikyou" or "State Religion." Yet, "Jikyou" for a while was fixed in its own fragemented self-imagery. As for Shinto, in 1900, the Office of Shinto Shrines became independent from the Office of Shrines and Temples in the Department of Domestic Affairs, and clearly Shinto and Shinto Shrines were part of secular state ideology. In the Bakumatsu and Meiji Periods, it ultimately was cut off from Restoration Shinto, thereby achieving this development on its own. This tells of the formation of an entirely new and modern Shinto within a secular "Jikyou." Konkokyo, moreover, as a religion establishes "kyousoku" and "kyougi." As a Shinto sect, it takes steps on the path toward recognizing a self-identity, namely as religious Shinto. As a result, dogmatization and systemization progress, and "Byoukinaoshi" or "illness-recovery" from the Tokugawa Period weathers. Also, as for progress in the Shinto religious order, from its foundation, the characteristics of a unified state and religion emerge, and thus there is an acceptance of significant restrictions. This dillema continues to persist as a problem in postwar Japan. Shedding light on Tokugawa Era practice also sheds light on where we can now take religious concepts.

본 연구는 뇌졸중 입원 환자들의 회복체험에 대한 경험을 이해하고 회복에 영향을 미치는 구성요소들을 알아보고자 하였다. Giorgi의 현상학적 연구방법론을 활용하여 재활병원에 입원해 있는 뇌졸중 환자 12명에게 3회의 대화를 진행하였다. 본 연구의 질문은 회복체험이란 무엇인가? 회복하는 과정에서 가장 중요하게 생각되는 것은 무엇인가? 회복에 있어서 재활이 주는 영향은 무엇인가? 이다. 사전 동의를 통해 대화내용을 녹음하였고, 과학적 현상학의 4단계에 따라 자료를 분석하였다. 뇌졸중 입원 환자들의 회복체험에 관한 16개의 요약된 의미단위를 통합하여, 10개의 하위구성요소와 6개의 구성요소를 도출하였다. 회복체험의 구성요소는 도움에 대한 부담감, 독립적 역할수행, 자기극복, 사회복귀, 심리적 지지, 회복에 대한 동기강화로 나타났다. 뇌졸중 환자가 입원 중 경험하는 어려움을 예측하고, 회복을 위한 중재의 방향성을 제시하기 위한 자료로 활용될 수 있을 것이다. 재활전문가들은 자기극복 및 가족과의 올바른 협력관계를 위한 전략을 세우고, 심리적 지지 및 동기 강화를 위한 치료적 관계형성을 토대로 뇌졸중 환자의 회복을 위한 중재를 제공해야 할 것이다.
