Keratinized ginigva has clinical singificance in periodontal health because it plays important roles in resistance to mechanical trauma, to penetration of bacteria, and to tensional stress by muscle attachment. In order to investigate the width change of anterior keratinized gingvial during transitional period, the width of kerainized gingiva on anterior teeth was measured annually in elementary school children with deciduous dentition until the successive anterior teeth were completely erupted. The distance from the gingival margin on mid-portion of crown to mucogingival junction was measured by Boley gauge(Hu-Friedy, U.S.A.) and was recorded as the width of keratinized gingiva. The difference of the width of keratinized gingiva according to sex and dentition was analyzed statistically by Student t-test. Following results were obtained : 1. In deciduous dentition, it was shown that the width of keratinized gingiva on maxillary central incisors($3.28{\pm}0.83mm$) was the widest(p<0.01), and that on maxillary lateral incisors, mandibular central and lateral incisors was $2.69{\pm}0.86mm$, $2.51{\pm}0.71mm$, $2.43{\pm}0.68mm$, respectively. 2. In mixed dentition, it was shown that the width of keratinized gingiva on maxillary central incisors ($5.10{\pm}0.86$) was the widest(p<0.01), and that on maxillary lateral incisors, mandibular central and lateral incisors was $4.35{\pm}0.83mm$, $3.51{\pm}0.60mm$, $3.57{\pm}0.66mm$, respectively. 3. The width of anterior keratinized gingiva was significantly increased after the successive anterior teeth were completely erupted(p<0.001). The width of keratinized gingiva on maxillary central and lateral incisors, and mandibular central and lateral incisors was increased by $1.82{\pm}0.83mm$, $1.65{\pm}0.69mm$, $0.99{\pm}0.39mm$, and $1.14{\pm}0.98mm$, respectively. 4. There was no statistical significance in the difference of the width of anterior keratinized gingiva between male and female(p>0.05).

Favus is a chronic dermatophyte infection of the scalp presented by thick yellow crusts within the hair follicles which leads to scarring alopecia. Favus is associated with poor hygiene and malnutrition so that it is seen almost exclusively in Africa, the Middle East and parts of South America with abruptly decreased incidence nowadays. The last report referring favus was published in 1996 in Korea, which might have historical significance. Herein, we report favus diagnosed in siblings in 1979.

본 연구는 진보적인 체육수업에 참가하는 현직교사 훈련 모델을 제시하고 있다. 이 프로그램에 참가하고 있는 사람들은 특수체육 분야에도 자격증을 가진 많은 사람들이 배출되어 정규 교육시설에 장애학생들의 참가를 증진시킬 수 있도록 통합교육의 필요성을 역설하고 있다. 체육교사는 통합교육에서 팀�p의 협력자로서 책임과 역할을 다해야 한다. 본 연구에서 제안하고 있는 모델은 공립학교 체제, 지역 오락 센터, 기부금으로 운영하는 프로그램, 그리고 대학 프로그램을 근거로 하여 단계별로 조직화된 교사 훈련 모델을 만들었다. A previous article(Hummel, 1982) described the importance and a success of mainstreaming inservice program. The inservice teacher training in physical education has been designed to increase the comfort levels of teachers with suggested strategies, materials, curricula, and alternatives for including handicapped children in their physical education programs. Many researchers suggested that some form of physical activities be essential to the development of the whole person(Miller & Sullivan, 1982). From the early 1900's Descoeudres(1928) has consistently stressed body movements of all kinds such as games, calisthenics, dance, and gymnastics for motor development. Recent research has confirmed that handicapped children should be given developmental perceptual-motor activities as an integral part of the cognitive process, substituting movement for abstract learning(Miller & Sullivan, 1982).

The purpose of this paper is to make a research on the basic direction of development in IOT. For this purpose, the concept, the prospect, and the importance of IoT are analyzed. The three important sectors for IoT diffusion are human, factories and cities. Among them, factories are found to be a most important one, indicating rapid innovation of manufacturing. Finally, considering value chain structure of IoT and convergence of technologies in the digital economy, the following policy recommendations are proposed. First, it is better for economic actors to focus on the hardware sector of IoT in the initial stage, but focus on the software sector such as services based on big data, later. Second, it is desirable to promote and take advantage of the phenomenon of convergence in the digital economy. When considering the time horizon, the first recommendation can be regarded as an advice based on short time period, but the second one on the long time. In the initial stage of IoT, policies of Korean government has been evaluated as good, but need to pay more attention to the areas of software and convergence technology.
