  • The purpose of this study was to evaluate an effect of change on head posture initial occlusal contacts with measuring the distances between initial occlusal contacts and maximum intercuspal position at different head posture in TMDs patient. For this study, 24 patients from age 13 to 36 were selected, they were examined health history taken, patients who have sign and symptoms of TMDs were examine before the study. For the normal group, 21 adults from age 23 to 25 were selected. They have normal or class I molar relationship, and have no other prosthetic restorations. Difference on distance between initial occlusal contact and maximum intercuspal position with mandibular kinesiograph$(MKG^R)$(K6 diagnostic system, Myo-tronic Inc, USA) in upright, supine, 45$^{\circ}$ extension, 30$^{\circ}$ flexion position of the head were measured. The Frankfort horizontal plane was used as a reference plane. The results were as follows : 1. There were significant differences between initial occlusal contacts of the normal and patient group on upright position and 30$^{\circ}$ flexion of the head(p<0.05, p<0.01) 2. The position of the initial occlusal contacts have a tendency to place anterior and inferior to maximal intercuspal position in upright position and 30( flexion of the head as well as posterior and inferior in supine position and 45$^{\circ}$ extension of the head in the normal and patient groups. 3. There were significant differences among the initial occlusal contacts between uptight and supine position; upright and 45$^{\circ}$ extension of the head(p<0.05); supine position and 30$^{\circ}$ flexion of the head, .and 30(flexion and 45$^{\circ}$ extension of the head in the patient group(p<0.01) The result have shown that after treatment on the supine position, it may be necessary to check occlusal contact on the upright position as well ass flexion of the head. It may need careful adjustment in occlusal condition on upright position of TMDs patient.

  • Cancer illness representations and screening history among residents of Kolkata, India, were investigated along with socio-demographic characteristics in an effort to understand possible motivations for health behavior. A total of 106 participants were recruited from community locations in Kolkata, India and completed surveys including demographics, the illness perception questionnaire-revised (IPQ-R), and previous experience with cancer and screening practices. Participants were 51.5% college educated, 57% female, 51.5% full-time employed with average age of 32.7 years (R: 18-60 years). Descriptive statistics were generated for the subscales of the IPQ-R, cancer-screening practices and cancer experience. Correlation analyses were conducted to investigate associations between cancer representations and socio-demographic variables. Univariate ANOVAs were calculated to determine gender differences in IPQ-R subscales and differences between participants who knew someone diagnosed with cancer versus those who did not. While 76% of participants knew someone with cancer, only 5% of the sample engaged in cancer screening. Participants perceived cancer as a serious illness with negative emotional valence. Younger age (r(100)=-.36, p<0.001) and male gender (F(1, 98)=5.22, p=0.01, ${\eta}_2$=0.05) were associated with better illness coherence. Males also reported greater personal control (F(1, 98)=5.34, p=0.02, ${\eta}_2$=0.05) were associated with better illness coherence. Low screening rates precluded analyses of the relationship between illness representations and cancer screening. Cancer was viewed as a threatening and uncontrollable disease among this sample of educated, middle class Kolkata residents. This view may act as a barrier to seeking cancer screening. Public awareness campaigns aimed at improving understanding of the causes, symptoms and consequences of cancer might reduce misunderstandings and fear, especially among women and older populations, who report less comprehension of cancer.

  • The costume originated from the idea that it could protect human beings from ferocious beasts. The military costume was from protection against an enemy equipped with weapons. Furthermore, the makers of the costume were afraid of supernatural powers and it made them devise an armour and decorate it by the concept of superstition for the purpose of overcoming it. The function of military uniform was important for increasing the protection against any enemies while they join in battle. However in harmonious time, it represented artwork of peace, dignity, and order. Since the uniform was a king of symbol to show their position, and their role. They could feel proud as a member of a military group they belong to and they gain honor, courage, patriotic sentiment through their military costume. The purpose of this study was to investigate the originality the military costume as it changed and developed continuously from ancient Egypt, Greece and Rome to modern times. This study was performed to show the comparison and characteristic marks of the past, and the influence of them on the modern military uniform. The method used in this study was using past manuscripts of the early times, information attained from domestic and foreign military documents and previously written reports. As a result, the military costume was one of many means of expression of their natural and social environment. It can be said that the most epoche-marking and powerful changes to the social environment are revolution or war. War absolutely has influenced on the changes of the changes of costume and the military armour according to the type of war and the development of weapons. Especially using the amour, the main purpose that of protecting the body has changed into distinguishing our forces from the enemy and instilling fear into enemy, Furthermore, the class who has the power has used it in order to express their power and dignity. Therefore, armour had required two rules to not only protect the body but also discriminating between classes.

  • To obtain demographic information on threatened gold-spotted pond frog (Rana chosenica Okada, 1931) populations, we determined the ages of 45 male and 13 female frogs (20 males and 9 females from Cheongwon and 25 males and 4 females from Tae-an) and compared the age structures and growth patterns of the two populations in 2006. The snout-vent length (SVL) and body weight of female frogs were greater than those of male frogs in both populations. Male frogs' ages ranged 2 to 7 years old and females' ages ranged 3 to 6 years old. In both populations, 4 years old male frogs were the most abundant age-sex class. The age structures of the two populations were significantly different and the growth coefficients of male frogs from the Cheongwon population were greater than those from the Tae-an population. The mean age of males from the Tae-an population was higher than that from the Cheongwon population. However, the SVL and body weights of male frogs were not different between two populations and there was no difference between the two populations in the mean male SVL at any age. The results could increase our understanding of the life-history of this threatened frog and may be useful in conservation planning.

  • SNe light curves have been used to understand the expansion history of the universe, and a lot of efforts have gone into understanding the overall shape of the radioactively powered light curve. However, we still have little direct observational evidence for the theorized SN progenitor systems. Recent studies suggest that the light curve of a supernova shortly after its explosion (< 1 day) contains valuable information about its progenitor system and can be used to set a limit on the progenitor size, R*. In order to catch the early light curve of SNe explosion and understand SNe progenitors, we are performing a ~8hr interval monitoring survey of nearby galaxies (d < 50 Mpc) with 1-m class telescopes around the world. Through this survey, we expect to catch the very early precursor emission as faint as R=21 mag (~0.1 Rsun for the progenitor). In this talk, we outline this project, and present a few scientific highlights, such as the early light curve of SN 2015F in NGC 2442.

  • The purpose of this study is to examine the effects of early full-time nonparental care during infancy/toddlerhood on children's socioemotional behaviors during the preschool period. Subjects for this study were 105 three- to five-year-olds from middle-class families in the U. S. A. Children were assigned to one of three groups according to their early care history. Children's social interactions with peers and caregivers during indoor free-play sessions in day care centers were observed for 20 minutes. The head teachers rated the children's social and emotional behaviors on two questionnaires. Mothers completed the Attachment Q-sort for attachment assessment for the preschoolers. In addition, mothers were asked to fill out a questionnaire on their parenting practices. Children who had received full-time nonparental care during infancy and/or toddlerhood were rated by their teachers as being more intellectually competent than children who did not receive full-time nonparental care during first three years of life. They were, however, rated by teachers and were observed by the researcher as being more aggressive than children with no full-time nonparental care. These children were observed to engage in less wandering/onlooking behaviors than children who had not had any full-time nonparental care. Children's attachment security scores and dependency scores did not differ as a function of early nonparental care histories. When the effects of early care patterns, sex of child, and current attachment security to mothers on aggressive behaviors of the preschoolers were examined by a hierarchical regression model, then any "pure" effects of nonparental care and of attachment security on child aggression were minimal after controlling for family background, child care center quality, and maternal childrearing practices. Strong buffering factors for the preschool children (family characteristics, parenting styles, and high quality nonparental care) mediated a possible risk factor of early nonparental care and promoted optimal outcomes for the children.

  • Mu-Guan(武冠) is a headgear of northern nomadic people's costume, Ho-Bok(胡服). It became a part of Chinese(中原) Costume through the adoption of Ho-Bok(胡服) by King Muryong(武寧王) of Kingdom of Cho(趙). Chinese(中原人) did not use it as the formal costume of high class but the Costume military or low-level classes because Chinese(中原人) reguad it as a practical costume only for low-level classes. In this process, Mu-Guan(武冠) and it's clothes had got changed. It became high in shape by an influence Hsien-pi(鮮卑族)'s headgear and became generous in it's going with clothes for Chinese(中原) Costume. It needs to attend that Mu-Guan(武冠) could be found in Koguryo(高句麗)'s mural paintings. Mu-Guan(武冠) of Koguryo(高句麗) had kept the same pattern from middle of 4C to late of 5C. Actually Koguryo(高句麗)'s Mu-Guan(武冠) was similar with Han(漢) dynasty's, but It was quite different from Qin(晉) or Wei(北魏) dynasty's which belong to same period with Koguryo(高句麗)'s. It is possible to guess at Koguryo(高句麗) advanced Mu-Guan(武冠) as their own. Koguryo(高句麗) could be aware of 'Changed Mu-Guan(武冠)'. Because there are frequent diplomatic event between Koguryo(高句麗) and Chiese Dynasties, Barbarian Dynasties. Moreover the guess have persuasion by the existence of 'Changed Mu-Guan(武冠)'in Jee-an(集安) district's mural painting as a Costume of holy person. In brief, It could be noticed that Koguryo(高句麗)'s Mu-Guan(武冠) is distinguished from Chinese and Barbarian dynasties' and Koguryo(高句麗) advanced Mu-Guan(武冠) in their own style.

  • This study examined a phenomenon of exaggerated hairstyle in the history of Western custom through publications related with Western costume and research papers. By adopting the criteria of Delong, M. R. to analyze visual forms shown by interaction between human body and costume worn over the body, it analyzed the formative characteristics by the interaction between hairstyle and costume. In addition, it inferred the aesthetic characteristics through content analysis of examined phenomenon focusing on socio-cultural background and costume socio-psychological precedent studies. Formative characteristics of exaggerated hairstyle applied by analysis criteria of Delong, M. R. were in pursuit of the emphasis style. This was clearly and intensively recognized by forming spaces for mostly closure style, part style, three dimensional style, determinate style, and space separation style. Regarding the interaction between hair and ornamentations, 'precedence of ornamentation' was pursued as ornamentations were recognized earlier than the hair itself. It means associative meanings of the surface effect were accompanied by emotions of 'intensiveness' and the pursuit of the attractive style. As for the interaction between hairstyle and costume, there were many cases of pursuing 'continuity' mutually and visually by connecting the hairstyle and the costume. Aesthetic characteristics of exaggerated hairstyle were inferred as 1) the expression of the sprite of the age(i.e. art, culture, politics, society, ideology, religion), 2) symbols of wealth, class, authority, and excellence, 3) pursuit of addicted desire to ornament, and 4) harmony through continuity with costume. This study verified that hairstyle was connected as a part of costume, or formed as a way to express deeper human psychology beyond just a part of a costume. It was also confirmed that hairstyle was an expressive method to express the spirit of the age, such as art, culture, society, religion, ideology.

  • Among many different approaches of study of history of Kokuryo clothing culture, this study attempted to understand the costume by including political , militarial , economical , cultural , and religious aspects of Kokuryo society. It also included pictures in mural tumbs and old studies in Kokuryo costume. Clothing culture related to political life clearly differenciated social status by restricting styles and colors of clothes according to peoples social status. Generally people in high social status wore clothes with detailed decorations invariety of colors, and also used more fabrics than people in low social status. Costume was also affected by military life style that needed to meet the vigorous physical activities. High rank worriors wore iron scaled shielded clothes with red decoration on it which identified different ranks of the worriors. Economy also contributed it role to affect the clothing styles in Kokuryo. Based on old studies of costume, this study focused on people's life styles that included hunting and weaving . Hunting clothes were differentiated by decorating wit feathers . Jowoguan(조우관) is one of the examples. Since weaving was a major economic power or factor, silk and flax were very popular. People even used those fabrics to pay tax. Regarding cultural aspect , this study emphasized on song and dance wear along with active wear. Song and dance wear specially decorated with poka dots, however men and women wear were claryly distinguished. Unlike other clothes that were restricted in colors and styles, song and dance wear were decorated in variety of colors. Lastly this study presents religious aspects of Kokuryo costume . Monks wore black clothing (내의) that was influenced from China and the Western Regions(서역). To emphasize their religious power, Gods in the pictures of mural tumbs wore clothes with wings and feathers. God of fire and agriculture wore simple dresses without much decorations which represented simple life style of working class.
