The author studied to determine the sex and age of 8 ancient human skeletal remains, which had excavated from ancient tombs located in Yeanri, Kimhae. Some kinds of personal identification methods their skulls and teeth were used for this study and the results were obtained as follows : 1. Sex determination was possible in ancient teeth from 4th to 5th century, using detection of X-Y homologous amelogenin gene by polymerase chain reaction. 2. DNA analysis proved that the materials examined were all male, but which always did not coincide with the results from other methods for sex determination including comparison of sexual differentiation of cranium and teeth and use of discriminant functions in the dental measurement. 3. There was little difference of the estimated ages between the methods by regression of pulp cavity and attrition in teeth. The ages from these two methods always did not coincide with ones from evaluation closure of cranial and palatal sutures. 4. Sex and age of the materials were determined as follows ; $\cdot$ Y9 was estimated to be male in early sixties. $\cdot$ Yl2 was estimated to be male in late twenties to early thirties. $\cdot$ Y37 was estimated to be male in early forties. $\cdot$ Y70 was estimated to be male in early sixties. $\cdot$ Y87 was estimated to be male in late forties. $\cdot$ Y109 was estimated to be male in early forties. $\cdot$ Yl29 was estimated to be male in late thirties to early forties. $\cdot$ Yl42 was estimated to be male in late fifties to early sixties.

It is known that the human stature and its related dimensions generally increase until the late teens or early twenties, remain relatively constant throughout early adulthood, and decline from early-to-middle adulthood into old age. However, there is exception that the length of the human ears, which continue to grow throughout life. In this study, 600 Korean male and female subjects aging from 17 to 89 were selected. Four different points of external ears including Pinna length, ear connection point length, Concha length, and Lobule thickness were measured along with other relative subjects' demographic data(e.g., age, stature, weight) to determine the relationship among these obtained data. The results showed that the age, sex, and different ethnic populations were functions of ear dimensions similar to the human stature. For example, the Pinna length increases as the age increases(r= 0.689, p<0.00l). The primary objective of this study was thus to provide anthropometric dimensions of Korean ear for the product designers and recommend the appropriate product design solutions in relation to human ear. Based on the results of this study, it is suggested that the continuing growth of the human body parts should be considered in the application of anthropometric data to the design of the things especially for human use.

This study researches the preferred ease of torso sloper according to body sizes and drop. For this, the eases of main body parts such as chest circumference, waist circumference, hip circumference, biacromion length, and waist back length were analysed; in addition, the drop differences of body and pattern were explored to find out characteristics of silhouette changes. The subjects were 55 women in their early 20s (aged from 20 to 24) and individual torso block made with muslin was corrected 1-3 times by a personal fitting. There were 3 meaningful results. First, the preferred ease were individually various; however, the eases of all torso blocks should be same at the pattern making step. Second, the eases were also significantly different among body size groups and the bigger group preferred less ease at the biacromion length, waist back length, armhole-depth, chest circumference, and waist circumference. Third, the eases of chest circumference and hip circumference were significantly changed among drop groups. To change their body drop, H-shape drop adopted less ease at chest circumference and more ease at hip circumference; however, A-shape drop adopted more ease at chest circumference and less ease at hip circumference.

The author has taken intraoral standard films by the paralleling technique of 6414 teeth in 838 patients ranged from early twenties to early sixties and analysed the change of pulp cavity in the mandibular posterior teeth by ageing. The obtined results were as follows : 1. There was no significant difference between the right and left teeth. 2. The degree of change of pulp cavity in female was higher than that in male. 3. The change of pulp cavity was increased by ageing. 4. The correlation between the degree of change of pulp cavity inmandibular posterior teeth (X) and age (Y) were : Male 1st premolar Y=13.22X3.37+ r=0.79 2nd premolar Y=12.09X+3.65 r=0.79 1st molar Y=11.90X+1.25 r=0.78 2nd molar Y=10.51X+10.43 r=0.83 Female 1st premolar Y=13.66X-2.49 r=0.86 2nd premolar Y=13.63X-2.42 r=0.86 1st molar Y=12.42X-1.44 r=0.79 2nd molar Y=11.42X+5.91 r=0.84

Today's young generation in digital era has a rich education environment and convenient life, on the other hand, there was negative impact on growth as normal body type because of adverse impact on an excessive study and insufficient exercise, etc. Also, for these people in IT culture generation, using small mobile including computer for long time is becoming main issue as changing factor in posture and body type in terms of spine like their neck disc. This body-typed characteristic reaches to normal adult body type in the process of physical development of adult woman and has least modification in body type. Therefore, despite of early young generation, body suitability of upper body clothes might caused imbalance. So, for intended to early 20s women, to design clothes with consideration on imbalance of body type by bended and curved spine, body type studies about size of upper body and forms are needed. As this researcher measured the body type of early 20s college women in metropolitan area, changes in body type of young generation with use of digital equipment recently were recognized since straight body type was decreased unequally and had characteristic in terms of changes to be bended body type. The changes of these body type should be considered to make clothes. Also, since there are some restrictions on this research objects in terms of local and numbers of measured objects, a broad interpretation of result on this research should be really careful.

This study aimed at investigating the change of fat in each body part according to the wearing of sport underwear made of specially-processed materials. in this study. 6 females made up of three early twenties, and three later thirties took part in the exercises for 12 weeks to to out the change of fat amount in body, square of body part by CT and obesity after and before an exercise. The results are as follows: In the obesity condition after and before an exercise, Roller's index shows that in case of 51 and 54, one level was lowered concerning the basic physical strength and optimal index was not changed. In the silhouette between body frames. there are differences between ages. The body fat rate decreased 35.95% on the average. and the amount of the body fat of females in twenties was more than that in thirties. The amount of body fat decrease with the lapse of exercising time, while the amount of body fat shows increased of 0.75%, which showed the minus correlation. The rate of averaged flat by CT went up after an exercise in every body part. and also the decreased value of subcutaneous fat was not proportioned to that of weight and girth. Inbody parts, the lower abdomen was shown 49.7%, navel part 47.7% and waist part 37.3% each in numerical value. In the thickness of subcutaneous fat concerning waist, the value of front-center line was the lowest, and followed by rear-center line and lateral line. 1204degree part in the navel showed the most fat layed, and the lowest fat layed was in the lateral part. Concerning the lower part of abdomen, under-skin fat was the most layed in 120degree part like that of navel part.

This essay attempts a historical examination of educational function of the novel. It pays attention to the eighteenth century sentimentalism, and its historical vicissitudes up to early twenties century. The eighteenth century is the period in which debates on the nature of emotion and its moral and aesthetic role have passionately taken place and the modern paradigm of thought on affect has been formed. This is why "affect revival phenomenon" in the late twenties century goes back to this period. This essay finds in Adam Smith the most sophisticated arguments on sympathy in their relation to the development of the novel; it examines the relationship of Smith's argument with modern novel in the tradition of sentimentalism, and its revision in modernist novel. Through this examination, it discusses how cognitive and non-cognitive approaches, the two representative positions in contemporary thinking on emotion/affect, have revised and transformed the eighteenth century sentimentalism.

This paper aims to research the historical development of the archival systems in the Soviet Union from 1917 to the 1920's. The Russian revolution was the turning point not only for the political and social changes but for the archival administration in Russia, as it provided the new Soviet regime with the chances to reorganize the archival institutions under Bolshevik rule. However, we must not forget the fact that the Russian Archival Workers' Union had taken part in the organization of the archival systems together with the Bolshevik revolutionaries. The Soviet government intended to transform the decentralized and poorly organized archival systems in the prerevolutionary years into the centralized and bureaucratized ones. In this meaning, the decree signed be V. I. Lenin on 1 June 1918 was estimated as the real basis for the Soviet archival centralization. Lenin's archival decree of 1918 encompassed the entire national documentary legacy, which was gradually extended to all types and categories of manuscripts and archival records by successive legislation. The concept of state proprietorship of all documentary records was designated "Single State Archival Fond"(Edinyi Gosudarstvennyi arkhivnyi fond), which was renamed as "Archival Fond of the Russian Federation" after the collapse of the USSR. The independent state administrative agency, that is, "Main Administration of Archival Affairs"(Glavnoe upravlenie arkhivnym delom) was charged with the management of the entire "Single State Archival Fond". While the Soviet Union reorganized its archival systems in the twenties, the archival institutions became under the severe control of the government. For example, M. N. Pokrovskii, the well-known Marxist historian and the political leader, headed the organizational work of archives in the Soviet Union, which resulted in the exclusion of the prerevolutionary specialists from the archival field in the Soviet Union. However, the discussions over the concept of "the Archival Fond" by B. I. Anfilov helped to develop the archival theories in the USSR in the twenties. In conclusion, the Soviet Union, having emphasized the centralization of the archives, developed its archival systems from the early period, which were the basis of the systematic archival institutions in Russia.

This text is an attempt to understand the psychological meaning of panic attacks occurring in the young people in their early twenties who play music. A panic attack is a type of anxiety neurosis known to occur primarily in their twenties and is characterized by extreme fear and terror accompanied by various symptoms in the autonomic nervous system. Situations with occurring panic attacks were examined in three cases combined with panic attacks and mood swings, suicidal ideation, and self-mutilating behaviors, and the psychological meaning of panic attacks was reviewed for each case. In the first case, panic attacks make one think or reflect with consciousness for someone who wants to remain unconscious. In the second case, for one who hesitates to move forward in life and finds oneself in conflict, panic attacks open the inner mind and allow one to come in touch with one's deeper mind, thereby opening possibilities to transcend the conflict. In the third case, one experience the instinct and impulse of desiring to realize the unconsciousness as panic attacks and thereafter consciously realize the impulse as well. Their panic attacks, which all seem to have different meanings, are likely a powerful approach of the unconsciousness to urge a renewal from the consciousness level of the youth period.
