In order to study the postures of Korean students, 4,448 students who lives in urban and rural community were participated as subjects and examined by using New York State Posture Rating Test Method with taking photographs. The results were subdivied into postures of body parts, total posture score, leg types, and lateral deviation and analysed as follows. 1. Postures of body parts 1) Head Tilt For elementary and middle school students, the cases of tilted head were shown more frequently in urban than rural and the ratio of the case of the tilted head was increased as grade was higher. On the other hand, high school studends had the opposite tendency. 2) Uneven Shoulder Height For elementary school childs, higher grades had better condition than lower grades, however, for high school students, those in urban had more cases of uneven shoulder than those in rural and girls showed more deviations than boys. 3) Scoliosis Rural childs had more cases of scoliosis than urban childs, but there were no differences of middle and high school students. 4) Uneven Hip Height Urban and rural childs showed some cases of uneven hip which belonged to normal ranges. Middle and high school studedns werw nearly perfect in the hip height, therefore the condition seems to change as they grow older. 5) Pronated Ankles For this part, those in rural showed better conditions than those in ruban in all age groups and, especially high school third grade students were more satisfactory in rural than urban(84% vs 50%) 6) Forward Head Elementary and middle school students appeared to be satisfactory regardless of age, sex and district, however 32% of high school girl students had forward head. 7) Round Shoulders Many students had round shoulders and some of them revealed severe conditions, There were large differences between urban and rural students. 8) Trunk Hyperextension Generally, girls showed better conditions than boys in trunk posture and, for high school boy students, conditions were differed according to their grades. 9) Sagging Abdomen More cases of sagging abdomen were revealed in ruban that rural for elementary girl students(30% vs 14%). For middle and high school students, there were differences between sex, boys showing more cases than girls in middle school and girls in high school. 10) Lordosis There were differences between urban and rural for elementary childs and high school boy students, however no differences were detected in other groups. Mean degrees of lordosis had a tendency of increasing as the age grew. 2. Total Posture Score For elementary childs, both boys and girls showed differences between urban and rural(75.95 vs 70.73, 75.16 vs 82.42), and, in rural girls seems to be more satisfactory than boys in comparison between boys and girls(p<. 001). In middle school group, rural students appeared to be significantly(p<.05) better than urban students for both sex(83.88 vs 81.93, 75.93 vs 75.02) and the result was same for the high school group(86.52 vs 84.03, 80.07 vs 78.10) 3. Leg types For elementary childs, girls revealed more cases of bowlegs and knock-knee than boys(6% vs 8.2%, 20.5% vs 30.3%). In high school group, the girls in rural showed more cases of bowlegs than those in urban(29.7% vs 13.0%) and, the knokc-knee, the result was opposite(19.3% vs 28.4%). 4. Lateral deviation 1) Head Tilt In elementary group, 11% of boys and 6.3% of girls had lateral deviation and, for high school students, 3.6% of boys and 5.4% of girls showed the deviations revealing girls had more cases of deviation than boys. 2) Uneven Shoulder Height 1.8% of elementary boys and 0.5% of girls had uneven shoulder and totally 1.5% of high school students showed uneven shoulder height. 3) Scoliosis 15.5% and 17.4% of elementary boys and 21.6% and 20.7% of girls deviated to right and left respectively. Urban students showed general trends to leftward deviation while rural students showed rightward deviation. 4) Uneven Hip Height In this part of posture, they showed good conditions in all age, sex, and district.

고영무,최한철,정재헌,정효수,최성욱 대한치과기재학회 1999 대한치과재료학회지 Vol.26 No.4

In order to investigate the various properties of dental magnetic materials studies on corrosion behavior, decreasing rate of magnetic flux density, amount of elements released, mean average surface roughness values and the changing of mean surface microhardness values for dental application were done. To increasing the corrosion resistance of dental magnetic materials, surfaces of Sm-Co and Nd-Fe-B based magnetic materials were plated with gold(Au), platinum(Pt), titanium(Ti), chromium(Cr) and cobalt(Co), and then electrochemical corrosion test were performed in 4 kinds of electrolyte solution(0.9% NaCl, 1% lactic acid, 0.05% HCl and modified Fusayama's artificial saliva). The results were as follows: 1. In Sm-Co and Nd-Fe-B based magnetic materials, the pitting corrosion of experimental group was higher than that of the control group, the experimental group was less corrosive than control hroup. 2. The amount of elements released from experimental group was more significantly decreased than that of control group. 3. Decreasing rate of magnetic flux density of experimental groups was significantly lower than that of control group after corrosion test. 4. The mean average surface roughness value of one(Sm-Co based magnetic materials not plated) of the control group was much increased in modified Fusayama's artificial saliva after first corrosion but that of the other(Nd-Fe-B based magnetic materials not plated) was much increased in 0.05% HCl solution. 5. The decreasing rate of surface microhardness values of experimental groups were lower than that of control group after corrosion, 6. Intergranular corrosion started first from the grain boundary of the control group and they advanced gradually to general corrosion, and the pitting corrosion occurred locally at area of existing pits in experimental group.

The purpose of this paper is to investigate and analyze the nation's consciousness about the social physical education by regional groups(big cityes, middle cityes, farm village, fishing villge). And the researchers are to find a way to populize this movement. These subjects for this investigation were chosen at random among the citizens in four region. 4,450 sheets of questionnaire were given to the citizen. And 3,587(81%) sheets of them were received from male(2,582) and female(975) citizens. The results of this investigation are as follows: 1. The nation's consciousness has not been still modernized and the nation tend to depend on their doctors rather than on the new active leisure sports, which is a passive and conventional way, to keep their health. 2. Most people have spent their leisures on nonactive hobby such as reading, listening to music, and watching TV rather than sports. 3. Most residents pointed out lack of facilities, and needed professional directors and various programs they could participate. 4. The opening of citizen athletic field and the gymnasiums to citizens was needed to recruit the lack of facility, and the participation to commercial sport ws differed by economical status and leisure time, however, they usually participated such activities as table-tennis, swimning and tennis. 5. To activate social physical education, first of all, an expansion of the facilities such as athletic fields and gymnasium is needed under the active support of government. 6. The facilities for young men and the handicapped is insufficient, and to prevent juvenile delinquency and guide them into the right way, we should lead them out to participate sports activity. And the facility for the handicapped is needed too.

치과용 자성 어태치먼트 재료의 안정성 개선에 관한 연구 : II.질화티타늄 코팅이 치과용 자성재의 내식성에 미치는 영향 Ⅱ.Effect of TiN Coating on Corrosion Resistance of Dental Magnetic Materials

Dental magnetic materials have been applied to removable prosthetic appliances, maxillofacial prostheses, obturator and dental implant but they still have some problems such as low corrosion resistance in oral environments. To increase the corrosion resistance of dental magnetic materials, surfaces of Sm-Co and Nd-Fe-B based magnetic materials were plated with TiN and then electrochemical corrosion test were performed in 4 kinds of electrolyte solutions(0.9% NaCl. 1% lactic acid, 0.05% HCl and modified Fusayama's artificial saliva). From this study, corrosion behavior, amount of elements released, mean average surface roughness values and the changing of mean surface microhardness values were measured comparing with control group of non-sputtered plating magnetic materials. The results were as follows: 1. TiN layer coated on magnet grows into preferred direction with lamellar structure and its thickness is 3.0㎛. 2. Sm-Co base magnetic materials coated with TiN have good corrosion resistance in 1% lactic acid and their pitting corrosion can not be seen. 3. Nd-Fe-B base magnetic materials coated with TiN showed good tendency of corrosion resistance in 0.05% HCl solution. 4. The amount of elements released from both Sm-Co and Nd-Fe-B base magnetic materials coated with TiN were more significantly decreased than that of uncoated magnetic materials. 5. The mean surface roughness values of both Sm-Co and Nd-Fe-B base magnetic materials coated with TiN were smooth than that of uncoated magnetic materials after corrosion test. 6. The decreasing rate of microhardness of both Sm-Co and Nd-Fe-B base magnetic materials coated with TiN were lower than that of uncoated magnetic materials after corrosion test. 7. Dental magnetic materials coated with TiN produced various corrosion products such as TiO, TiO₂, Ti₂O₃on the surface and resulted in better corrosion resistance than uncoated magnetic materials. In conclusion, it is considered that the corrosion problem of dental magnetic materials could be solved to some extent by EB-PVD with TiN on the surface of dental magnetic materials.
