The traffic accident types are largely classified into vehicle to vehicle accident, vehicle-to-person accident and single-vehicle. Especially, the single-vehicle accident types are severe when the vehicle crashed into road facilities such as bridge, piers, utility poles. The severity of single-vehicle accidents are ten times higher than that of all other accidents types. It is needed to consider to reduce accident severity. This study was conducted to develop crash worthy safety design facility to ensure the vehicle occupant safety. The simulation and the crash tests were conducted for assessment of the safety performance to check the criteria of CC2(Crash Cushion 2) level. THIV(Theoretical Head Impact Velocity) and PHD(Post-impact Head Deceleration) were used to assess occupant impact severity for crashes. The non-redirection collision test conditions for 900 kg and 1,300 kg-head on crash tests, 900 kg-1/4 offset crash tests, 1,300 kg-head on crash test with $15^{\circ}$angle were conducted. The simulation and experiment test result showed that THIV values were below 44 km/h criterion, PHD values were below the 20G. The development non-redirective crash cushion is expected to be used for the fixed object such as bridge piers for assuring occupant safety.

Headdress which adorns the head has been used not only as a type of dress but also as a vehicle to express the human's mentality and a tool to convey ideas. This study first examines the type of headdress observed in the world folk costumes and investigates their geographical distribution and aims to examine how the types of headdress are inter-related to the peoples' natural environments, way of life and cultural background such as religion and aesthetic, ethical standards. Headdress used as important elements of many peoples' folk costumes can be categorized into scarf-type, hat-type and adornment-type. Veil-type, the one of scarf-types, was developed in Southwestern Asia and Arabic Africa influenced by natural and religious factors. This type is more simplified in Turkey and Eastern Europe and only covers head and neck in the former and only head in the latter while also being called 'headkerchief-type'. Hat-type is observed in many different parts of the world. Adornment-type has been used to symbolized one's noble social status and authority in societies dominated by shamanistic cultural background; it was also used in Far East out of the motivation to fulfil one's aesthetic desire. Headdress though it was originally made from the idential purpose of wearing, has developed into the various types affected by each people's natural environments, emotion and ways of life.

The purpose of this study was to analyze the effect of orthopedic forces on the craniofacial complex utilizing the three kinds of the head gear. (high pull head gear, straight pull head gear, cervical pull head gear) For this study, the teeth and alveolar bone and palate were reproduced from birefringent materials and other parts of craniofacial complex were coated with birefringent material on the model. The effect of orthopedic forces on the craniofacial complex was analyzed by photoelastic method using transmission polariscope and reflection polariscope. The results were as follows. 1. The cervical pull head gear had the greatest tipping effect on the maxillary molars and high pull head gear had the least tipping effect. 2. In areas stressed, the cervical pull head gear stressed the greatest degree. 3. Only cervical pull head gear produced stress at the zygomaticofrontal suture and the posterior region of palate. 4. The straight pull head gear and high pull head gear produced stress at just inferior to the anterior nasal spine. 5. The cervical pull head gear and straight pull head gear produced tensile stress at the fronto-maxillary suture. 6. The pterygoid plates of the sphenoid bone, the zygomatic arches, the junction of the maxilla with the lacrimal and ethmoid bone, and the maxillary molars were affected by three types of head gear.

The purpose of this study is to investigate the characteristics of fur and leather clothes of minority races of China in Northeas and Inner Mongolia. To examine their characteristics, the clothes and ornaments were classified into four types: headwear, clothes, footwear, and accessories. First, headwear was divided into animal head-shaped, petal-shaped, round-shaped, and cone-shaped head wear. Among them, the animal head-shaped headwear was made by making the best use of the shape of animal's head and it was used as the best disguising method when hunting. Second, clothes were composed of upper garments and lower garments. For the upper garments, Po and Jeogori were worn and pants were worn for the lower garments. The clothes were decorated with lining, applique, or top-stitching on the outer collar, neck circumference, and the edge of sleeves and pants. Third, for the footwear, high boots of leather were developed to meet the needs for a convenient life in the plains. In some areas, fur shoes and leather shoes were also used. Finally, accessories included bags and gloves. Bags were usually decorated with fur on the outside or with a fringe or applique of tanned leather. Gloves were lavishly decorated with embroideries and partly with fur or leather.

Background: There is minimal literature on the morphology of partial distal biceps tendon (DBT) tears. We sought to investigate tear morphology by retrospectively reviewing 3-Tesla magnetic resonance imaging (3T MRI) scans of elbows with partial DBT tears and to propose a basic classification system. Methods: 3T MRI scans of elbows with partial DBT tears were retrospectively reviewed by two experienced observers. Basic demographic data were collected. Tear morphology was recorded including type, presence of retraction (>5 mm), and presence of discrete long-head and short-head tendons at the DBT insertion. Results: For analysis, 44 3T MRI scans of 44 elbows with partial DBT tears were included. There were 9 isolated long-head tears (20%), 13 isolated short-head tears (30%), 2 complete long-head tears with a partial short-head tear (5%), 5 complete short-head tears with a partial long-head tear (11%), and 15 peel-off tears (34%). Retraction was seen in 5 or 44 partial tears (11%), and 13 of the 44 DBTs were bifid tendons at the insertion (30%). Conclusions: Partial DBT tears can be classified into five sub-types: long-head isolated tears, short-head isolated tears, complete long-head tears with partial short-head involvement, complete short-head tears with partial long-head involvement, and peel-off tears. Classification of tears may have implications for operative and non-operative management. Level of evidence: III.

The purpose of this study is to investigate the relationship between the Enneagram personality types and the anger expression styles, and to see how the relationship depends on the gender. The subjects, selected by the convenience sampling method, are 315 college students. The instrument is the Korean Enneagram Personality Types(Yoon 1999), which categorizes the personal types into the gut-center, the heart-center and the head-center. On the other hand, the anger expression styles, which is the anger-control as a functional role, and the anger-out and the anger-in as a dysfunctional role, is measured by the Korean version of STAXI(Chon et al 1998). The major findings of the study are as follows. First, comparing the personality types of students, the ratio of the students of the gut-center, that of the head-center and that of the heart-center types are in descending order. Second, It is found that students rely on the anger-out more than the other two expression styles. There also exist the gender differences in terms of the level of the anger expression: female students tend to express the anger-out and the anger-control significantly more than male students. Third, the relationship between the Enneagram personality types and the anger expression styles of students are statistically significant such that students of the gut-center style express the anger-out more severely than the head-center and the heart-center. Therefore, the findings from the study may become the basis on which the education program is designed for the sake of the psychological adjustment of college students, especially taking into account the gender differences.

This study aims to suggest basic data for the production of hats for aged women. The subjects were 151 females who are 60 years old or above and live in Busan. Their hat-wearing reality was inquired and their head parts were measured, which led to the following conclusion: 1. Results of Hat-Wearing Reality Inquiry 64.9% answered they are unsatisfied with the size system of the available hats at present, implying the necessity for improving the current dimension system. 92.7% responded hat dimensions need to be subdivided, while 97.4% were for the necessity of hat size system. 74.8% expressed their will to buy ordered hats because they can find the hats of right sizes and designs. 2. Results of Head-Part Measurement Experiments According to head-part measurement, head circumference A was 53.26cm, head circumference B 54.19cm, and head circumference C 57.69cm on the average. Cluster analysis revealed three types. Type 1 (24%) with small head length and circumference is the smallest head with a wide upper part. Type 2 (33%) has long head height, short bitragion arc A, and thick head breadth. Type 3 (43%), owing to big head circumference and length as well as high values in vertical items. Considering head circumference B (HCB) and bitragion arc A (BAA), a new hat size system of 3 sizes (HCB: BAA) was chosen: S (52cm: 29cm), M (53-55cm: 30cm), and L (56-57cm: 31cm).
