The attempts in this study were made to evaluate the variations in some needle characteristics of Pinus thunbergii between individual trees within population, between populations and between the hypothesized climatic districts. This species occurs naturally along the southern seacoast of Korea penninsula having a relatively mild maritime climate. The followings are the summarized results. The coefficients of variation of the needle volume and needle serration density were generally higher than those of any other traits studied. The significant differences of variations of needle cross section form factor between individual trees within population at 1% level, except only the Young gwang population, were affirmed. In the case of the eastern seacoast district, where the three study populations are included, significances of variation differences were calculated, 5% level at needle serration density and cross section area and 1% Level at needle volume. The very high significant difference of the variations of needle cross section form factor and needle longitudinal form factor were shown between population of the western seacoast district and 5% Level significance at needle volume in the southern seacoast district. The high significant differences between districts in respect to needle cross section form factor and cross section area were calculated. The Duncan's multiple range test showed the dissimilarity of the said characteristics between the hypothesized climatic districts. Summing up the results obtained so far, individual tree and population variations were markedly noted statistically and these may be extended to the silvicultural technology.

We investigated whether the 81 items of the Gray-Wheelwright test correctly measure the concept of Jung's typology and aimed to refine the test. Participants (n=431) completed the Gray-Wheelwright test, and the results were analyzed using factor analysis with the varimax rotation and the maximum likelihood extraction method. A pair of opposing attitudes, introversion/extroversion, or one of the two pairs of opposing functional types, thinking/feeling or intuition/sensation, was labeled to the extracted factor according to the majority type of the items in the factor. The minority items or items not included in any factors were excluded from making a short form of the Gray-Wheelwright test with 45 items. We used intraclass correlation (ICC) coefficient and Cronbach's alpha for the test-retest reliability and internal consistency of the test, respectively. The newly developed short form of the Gray-Wheelwright test measured the Jung's personality types well, which was comparable to the original one while reducing time and effort required for the testing.

Recently, design has emerged as a key factor of successful product development. This study reviewed the elements of form with a view point of addressing and defining the elements of aesthetics and how they influence consumer aesthetic response. Though past researches related to form aesthetics reported that form aesthetics exist as a single element with other sub-elements, this research made further investigations into form aesthetics and reported that form aesthetics in product design can be broadly divided into form aesthetics and content aesthetics. Empirical studies on each category was undertaken and from the results obtained, it was concluded that typicality is a dominant element in content aesthetics while balance is a dominant element in form aesthetics. Also, the study investigated the effect of conditional variables such as price and people on each category and it was observed that both content and form aesthetics elements are affected by conditional variables such as price, people. Furthermore, the study reports that both content and form aesthetics elements are mutually correlated and both categories affect user's aesthetics response. It is intended that the results obtained from this work will contribute to theoretical knowledge of aesthetic elements and can be put to use by product design and manufacturing companies.

This study deals with the occurrence and application of 'Fun' as a linguistic function through form-giving. As a linguistic function, Fun could be defined, in a broad sense, as an emotion of desire when in relation to artifacts, and, in a narrow sense, as a physical or mental response when a person discovers unexpected information or artifacts. Hence, the occurrence of 'Fun' could be an analogy of a removal of a 'mental block' from using (or perceiving) artifacts. As an aspect of cognitive psychology, the context of form-giving, which has meanings in both artifact and design activity, will deal with an important factor of form-giving. From that, the elements of the context and the transformation of the elements are suggestive of 'Fun-oriented form-giving'. Hence, this study will show how to deal with that elements, what is required condition on it, 'Fun' in form-giving, and the Mechanism of Occurrence of 'FUN' based on this study, will be expected to apply them for product-concept effectively and Form-Giving fashionably.

An esthetically pleasing result in denture service is dependent upon several consideration. Esthetic considerations for the edentulous patient include tooth size, shape, arrangement, positioning, gingival contour, age, sex, personality differences, and ethnic type. Especially, the form of anterior artificial teeth is an important factor on the esthetics. The selection of artificaial teeth requires understanding and knowledge on physical and biologic factors and has to meet the indivisul esthetics and functional needs of each patient. However, the selection of artificial teeth is based on the large degree of subjective judgement of the dentist, Therefore, this is one of the most unscientific processes. Many attempts have been made to find a guideline for the selection of artificial teeth. Temperamental theory by White and Hall utillized with the physical characteristics such as body size, body form, color of eyes and hair, and disposition. SPA theory by Frush and Fisher utilized with the basis of sex, personalities, and age of the indivisual. There has not been provided for a guideline and study on the selection of artificial teeth for Koreans yet. This study was aimed to evaluate the William's typal matching theory in Koreans. 1. The facial forms of korean adult were ovoid(46.3%), square(36.7%) and tapered(17.0%) form. 2. The anatomic forms of natural maxillary incisors were ovoid(45.3%), tapered(31.3%), square(23.3%) form. 3. The forms of face and natural maxillary incisors were ovoid(21.9%), squared(11%), tapered(6.3%). 4. The natural maxillary incisors were similar in form to the facial form only in 39%. There was no correlation between the form of the face and the form of natural maxillary central inisors in Koreans. 5. Artificaial teeth which was selected according to the typal matching theory did not represent the form of the natural teeth in 61 per cents of the fatal, but it felt that they harmonized with the form of the patient's face and produced good results.

Centrifugation is a method to create functionally graded materials (FGM) with a thermosetting matrix. In this study the movement of short carbon fibers in an epoxy resin during the centrifugation process was modeled to determine the fiber distribution in the final product. For this purpose a form factor K was introduced to modify a set of equations that was previously shown to be valid for the motion of spheres. It was shown that the results of the simulation were in good agreement with the experimental data, when an empirical K factor of four was chosen.

The primary objectives of this study are twofold. One is to examine the psychometric properties of Family Empowerment Scale(FES) developed by Koren, DeChillo and Frisen(1992). The other is to develope a short-form FES. Data collected from 337 members of Parents' Solidarity of Children with Disabilities were used. FES had good internal consistency, but the results of confirmatory factor analysis(CFA) did not support the theoretical factor structure of the scale. Basic analyses such as correlation and descriptive analysis were performed to examine the characteristics of individual items and identify the limitation of the orignal FES. In addition, a series of CFA were carried out to develop a short-form FES. Finally 15 items were selected based on theoretical rationale and the results of CFA. Cronbach's ${\alpha}$ and the model fit indices for the short-form FES indicated that this measure has good construct validity as well as internal consistency. In discussion, usefulness and potential contribution of this study were explored in relation to content development in the area of measuring instruments.

The neck is the human body is closely con-nected with the life and properties of keeping warm as one of the opening part in clothes. In ancient times it was put on necklace for the protection of neck and in Rome it was worn muffler called focale for the protection of neck throat. in addition cravat directly originated in necktie today was primarily worn for the protection of soldier's neck and has been turned into decorative purpose until today. As the ornament is developed to vari-ous kinds of form the neck decoration is changed and grown again and again. Therefore this thesis studies history of the neckwear and various the symbolic factor. The first factor is the social. The neckwear shows the social position class and status and does social mutual interaction as conversation starters. The second factor is the mental It express individuality fondness attitude and is felt to be indignity by being forced to be worn. The third factor is the political. it shows political tendency by indicating the royal sign or part's sign in necktie like the French royal-ist's green muffler The forth factor is the man's sexual. I expresses wearing stock being brave symbol-izing independence. The sixth factor is the traditional. It is worn with appearing traditionand custom and one of cultural movements. The seventh factor is the ideological. It symbolizes the freedom of suffragettes and emancipation of woman. The social factor is the most extensive among them. The neckwear is various in the way of expression like its kinds and is generalized, It functions as a independent part of clothes.

Factor analysis was applied to the phenotypic correlation matrix of 15 linear type traits (scored linearly 1 to 50 points) for 2035 Holstein cows of 38 sires computed from data collected between 1988 and 1992 in Beijing Shuangqiao Farm and Beijing Xijiao Farm. The 15 linear type traits were stature, body strength, body depth, dairy form, rump angle, rump length, rump width, rear leg side view, foot angle, fore udder attachment, rear udder height, rear udder width, udder cleft, udder depth and teat placement rear view. The first four components accounted for 49.1% of the total variance in type scores. Factor 1 reflected strong cows, with deep bodies, with long and wide rumps, and tall in stature. Factor 2 reflected cows with well attached fore udders, wide rear udders and whose udders were supported by strong suspensory ligaments with close teat placement. Factor 3 reflected cows with good dairyness, sickled in the hocks, high rear udders and udder floors above the hocks. Factor 4 reflected cows with sloping rumps from hooks to pins and with steep foot angle. Principal component and factor analyses are useful to clarify the relationships among type traits.
