There is a change of the growth pattern and the growth rate of human crarniofacial bone with aging. The three dimensional growth of the each bone is different by the effect of the growth center. By the same token, the gross morphology can change as the bony skeleton changes. In this study, we studied the cephalometric films of normal male Koreans, age range from 7 to 16 years. And then, the data were compared to those from the adult group. The results are as followings ; 1. We are presenting the data of the height, depth, width, and cephalometric angles of the craniofacial skeleton of studied group. 2. The facial bony growth is slower than that of the cranial bone in each direction. The growth rate of the facial bone by depth, width and height is faster than that of cranial bone with the aging. 3. The horizontal growth of the mandible is slower than that of the maxilla and the cranium. 4. The proportional ratio of upper face to that of lower one is constant regardless of the age. The ratio was 43 : 57. 5. SNA and SNB angles are slightly increase with the growing age, but ANB angle is reduced with the aging. 6. As SN-MP and Pal-MP angle are reduced with the aging, so as the opening of the mandibular plane to the cranial bone. Although there is a increment of posterior mandibular height, the position of the mandibular symphysis is constant regardless of the age.

This review is focused on the research findings concerned with training of perceptual skill in motor expertise as well as the introduction and theoretical approaches of motor expertise. Although there exist some historical precedents to the morden study of motor expertise, a concerted research focused upon motor experts, especially sport applications, is a relatively recent phenomena. Also, the multidisciplinary and inter-disciplinary research on motor expertise result from the growing interest in expertise in the motor learning and control field. The majority of published research on motor expertise in motor learning and control field, has been concerned with the more theoretical issues of describing the experts' charateristics and developmental precess of motor expertise, including perception, making-decision, and motor execution. Skilled perception, in particular, is considered as an important determinant of sports expertise. Thus, perceptual skills, such as processing of contextual information, visual search strategy, and expectation, and training methods of perceptual skills is thought hot topics in motor expertise.

Traditionally, the methods of treating male pattern baldness has been classified as hair graft, scalp transposition flap and scalp reduction. The most effective method of treating baldness in the frontal region in the flap technique, which is ideal for getting a sufficial amount of hair to cover an extensive area of baldness at one time. Since the first description by Dardour in 1983, the one-stage preauricular flap has shown the excellent result in the treatment of male pattern baldness. In this paper, the authors used One-stage Preauricular flaps to treat 15 frontal baldness patients with various causes from January, 1995 to April 1996. This method is suitable for Types II and III baldness, which, according to Hamilton classification, is a mild baldness where the hairline retreats in the front and the temporal region is a triangle. Its advantages include high hair density, anterior direction of hair growth, the fact that it can be done in a single stage under local anesthesia, and finally, an aesthetic result characterized by a pleasing frontal hairline with natural temporal recess. This surgical technique is not frequently used when reconstructing frontal hairline but it can bring satisfactory aesthetic results if conducted on the cautiously selected patients under the age of 40 who are non-smokers with good skin elasticity. The technique can also be applied primarily in reconstructing frontal hairlines of male pattern baldness patients belonging to other types of Hamilton classification. Adjuvant micrografting refined the frontal hairline for the most natural-appearing result.

외적-조절 상황에서의 숙련도와 시각탐색 전략

본 연구는 외적-조절의 특성을 가진 배구 종목을 대상으로 하여 상대팀 세터의 세트 방향을 예측하는 데에 필요한 사전시각단서를 획득하기 위한 시각탐색 전략의 숙련도에 따른 차이를 밝히는 것을 그 목적으로 하고 있다. 시각탐색 전략의 결과는 평균시선고정시간과 시선고정위치로 살펴보았다. 그 결과, 기술 숙련도가 높을수록 높은 탐색율, 즉 시선의 고정시간이 적고 이동 수가 많은 시각탐색 전략을 사용하는 것으로 나타났다. 또한 세터 조건에서는 숙련자는 세터의 머리 영역에 초보자는 세터의 상체 영역에 시선을 고정하는 시간의 비율이 높았으며, 단순 및 복잡 공격 조건에서는 숙련자가 다른 두 집단에 비하여 공격자 영역에 대한 시선고정시간의 비율이 매우 높은 것으로 나타났다. 이는 숙련도와 상황 조건에 따라서 주로 활용하는 사전시각단서가 다르다는 것을 의미하는 것이다.

The ideal surgical approach to treat craniomaxillofacial fractures should provide maximum exposure of the fractured segments, ensure less potential for injury to facial structures, and allow for good cosmetic results. The most frequently used approach is the coronal incision. However, the coronal approach poses some disadvantages. The most common complication is widening of the scar at the head. The inevitable scar, whether narrow or wide, produce a natural separation of the hair. Also, hairline recession may expose the scar above the level of the ear and preauricular sensory deficits and motor deficits involving the frontal branch of the facial nerve have been reported. In order to avoid above problems, we have used zig-zag coronal incision with a postauricular extension from September, 1996 to May, 1998 in 35 cases with diagnosis varying from zygoma complex fracture to extensive facial fracture. Clinical follow-up ranged from 2 to 22 months. In our series of 35 patients, one patient had hematoma, one patient transient weakness of the frontalis muscle and one patient had sensory deficit. We found that this approach maintains the advantages of lowering the pivot point but also lessens the disadvantages of an anterior incision and unlike the straight-line coronal incision, this incision line is immediately much less visible.
