      • 일반 이벤트 의식에 관한 조사 연구 : 스포츠 이벤트를 중심으로 focus on sports-event

        남희은,이근모 釜山大學校 附設 體育科學硏究所 1998 體育科學硏究所 論文集 Vol.14 No.-

        The purpose of this study was to investigate a survey on preferences for events and design a specific way to increase more participation in sports-events as well as general events. The conclusions were as follows; 1. The term "event" was more farmiliar with younger generation. 2. Regarding the definition of events, the majority of people both genders defined it as "event or festival designed in advance with precise purpose". 3. For male respondents, sports events were the popular in participation. 4. The majority of males showed higher satisfaction with sports events than females. 5. People regardless of their ages ranked mass media as the first sources for events information. 6. The main obstacle to participation in events activities was a lack of time among the people having their own occupations a part from students.

      • 스포츠이벤트의 경제적 효과와 발전 방향

        남희은,김윤숙,이근모 釜山大學校 附設 體育科學硏究所 1999 體育科學硏究所 論文集 Vol.15 No.-

        Although sports events have so many extend effect on the field of politics, diplomatic, social, culture, and economic, especially the economic effect is very important. In this view, this study was researched that the economic effect through sports events and development direction to induce a long term effects. The economic effect through the sports events are as follows; 1. Direct effect of economic : construction, arrangement of the lower part and traffic, etc. 2. Effect related consume : public business fund, operation fund related event facilities, participation fee, and ticket fee, selling income of gift related events, food, information service, rental service, insurance service, income of transport and lodging. 3. The effect of sports industry development : sports products, the advance of technological industry, facilities, information technique. 4. The effect of employment promotion : promotion for short period, social resource for a long term effect with accumulation of brain and management know-how. The way for advance to maximize the economic effect of sports events are as follows; 1. Correspondence for periodic request. 2. participants of sports events should prepare proper event facilities. 3. Correspondence for the movement from urban-centered sports events to local events. 4. A pattern of event which have from of enterprise that a enterprise will use the sports events as means of advertisement. Sports events should present the innovation vision for new-life to get original meaning and function.

      • 우리나라 여성 노동력 상태의 동태적 특성 연구

        남재량,류근관 서울대학교 사회과학연구원 1999 한국사회과학 Vol.21 No.4

        본연구는 「경제활동인구조사」원자료를 패널자료 형태로 연결시켜 우리나라 여성노동력 상태의 동태적 특성을 밝히고 이를 통해 저량측면에서 나타나는 전형적 사실들에 대한 설명을 시도하고 있다.분석에 따르면 여성의 강한 비경제활동 인구화 경향과 높은 실망실업효과가 우리나라여성노동력의 가장 중요한 동태적 특성이다.이러한 특성은 시간에 걸쳐 점차 약화되고 있어서 빈번하던 여성의 노동력상태 변화정도가 점차 하락하는 추세를 보인다.이러한 유량 요인들이 경제활동참가율과 실업률의 성별격차 및 그 격차들의 시간에 걸친 하락이라는 저량 측면의 전형적인 사실들을 나타나게 한 주요 원인이다. This paper constructs a sequence of moving panel data using the raw data files of the Korean current population survey, a monthly household survey conducted by the Korea statistic bureau.Analysing these panel data, this paper finds that strong tendency toward no labor force and a high discouraged worker effect are two major characteristics of the Korean female labor force.These characteristics cause both female labor force participation rates and the female unemplyment rates to be lower than their male counterparts.These characteristics are commonly observed for each age and education subgroup, but are decreasing over time.

        치과용 도재분말의 제조 및 물리적 성질

        염근창,고대진,장감용,이서영,김경남 大韓齒科器材學會 1994 대한치과재료학회지 Vol.21 No.1

        In this study, the prepared glasses were heat-treated to precipitate the leucite crystal in order to control the thermal expansion coefficient which is an important property of dental porcelain powder. The effect of addition of Li₂O and Na₂O on the amount of the precipitated leucite crystal were also examined. The mixing ratio of the leucite-containing glass must be controlled to match the thermal expansion coefficient of dental porcelain to that of metal. The physical properties of the dental porcelain powder prepared in this study were characterized. The results of this study were obtained as follows : 1. Conditions for the preparation of the maximum amount of leuctie crystal were compostion L-2(2.0 wt% Li₂O added) heat-treated at 950℃. 2. The phase of the precipitated crystals was turned out to be the tetragonal leucite crystal. 3. Maximum relative crystallinity was 64.2% for composition L-2, heat-treated at 950℃. Its linear thermal expansion coefficient was 16.1×10-6/℃ in the range of room temperature to 500℃. 4. The optimum mixing ratio of the leucite-containing glass was 45% in order to match the thermal expansion coefficient of dental porcelain to that of metal. In this case, the thermal expansion coefficient of the prepared dental porcelain was 10.6×10-6/℃ (∼500℃). 5. The physical and chemical properties of the prepared dental porcelain were suitable for the requirements of ISO 6872 and 9693.

        乳齒列期 齒列穹 形態에 關한 硏究

        金旺根,金南洪 大韓小兒齒科學會 1985 大韓小兒齒科學會誌 Vol.12 No.1

        This study was to investigate the fitness of the primary dental arch to the parabola. The samples of 91 plaster casts were obtained which were taken from children with normal occlusion, aging from 3 to 5 years. Landmarks on the stone casts were marked on measuring glass which was superimposed on the stone casts, and transfered and measured to the tracing paper. The points on the tracing papers were digitized, and scattergrams and statistics were performed by the computer; PRIME 750, IBM Co., U.S.A.. The results were as follows: 1. The fitness of the primary ental arch to the parabola was above 92% in the upper dental arch, and was above 91% in the lower dental arch. 2. Constant value A of upper dental arch line passing the midpoints of primary dentition was -0.54 and that of lower ental arch was -0.59, and the upper dental arch showed more expended parabola than the lower dental arch. 3. The dental arch line passing the buccal cusp tips of the primary posteriors and the midpoints of he primary incisors were more fit to the parabola than the dental arch line passing the midpoints of the primary teeth. 4. The ratio of oblique arch length to intermilar width was divided into 4 groups by the quaters, and the mean parabolic equations and curves were calculated and drawn.

        Sandblasted large grit, acid etched 표면처리에 따른 교정용 미니 임플랜트의 제거회전력에 관한 연구

        오남희,김성훈,국윤아,이근혜,강윤구,모성서 대한치과교정학회 2006 대한치과교정학회지 Vol.36 No.5

        Sandblasted large grit, acid etched(SLA) 표면처리 된 교정용 미니 임플랜트와 평활면을 가진 교정용 미니 임플랜트 사이에 제거회전력과 조직학적 소견을 통해 표면처리된 교정용 임플랜트의 임상적 가능성에 대하여 알아보고자 하였다. 실험재료로는 길이가 9.5 mm, 외경이 1.8 mm인 custom made, screw shaped, titanium implants가 사용되었다. 미니 임플랜트는 두개의 군으로 분류되었는데 SLA군은 20개의 SLA 표면처리된 미니 임플랜트이었고, 평활면군은 크기와 형태가 같지만 SLA처리공정이 생략되어 제작된 20개의 미니 임플랜트로 구성되었다. 이들은 10마리 가토의 경골에 식립되었다. 각각의 가토의 우측 경골에는 SLA군의 미니 임플랜트 2개가 식립되었고, 좌측 경골에는 평활면군의 미니 임플랜트 2개가 식립되었다. 각 군에는 식립 직후 Ni-Ti coil spring에 의해 약 150 g의 지속적인 견인력이 주어졌다. 식립 6주 후에 10마리의 가토를 희생하였고, 안정된 상태에서 Ni-Ti coil spring을 제거하였으며 digital torque gauge를 이용하여 제거 회전력을 측정하였다. 식립 6주 후에 SLA군의 경우 (8.29 Ncm) 평활면군 (3.34 Ncm)에 비해 더 높은 평균 제거회전력을 나타내었고 조직학적 소견에서도 screw 하방에서의 신생골 형성이 관찰되었다. SLA 표면처리된 미니 임플랜트는 평활면 미니 임플랜트에 비해 좀 더 강한 교정력에 저항할 수 있을 것으로 예상되었다. Objective: The purposes of this study were to evaluate the differences between sand blasted, large grit and acid-etched (SLA) treated mini-implants and smooth surface orthodontic mini-implants in relation to the removal torque as well as the histologic analysis. Methods: Custom-made, screw-shaped, titanium implants with a length of 9.5 mm and an outer diameter of 1.8 mm were divided into 2 groups; the SLA group (20 SLA treated orthodontic mini-implants) and the smooth surface group (20 smooth surface mini-implants), and placed in the tibia metaphysis of 10 rabbits. Each rabbit had 4 mini-implants placed, 2 in each tibia. The right tibia were implanted with the SLA group mini-implants and the left tibia had the smooth group mini-implants placed. Each mini-implant group were immediately applied with a continuous traction force of 150 g using a Ni-Ti coil spring. The rabbits were sacrificed 6 weeks post-surgically. Subsequently, the legs were stabilized, the Ni-Ti coil springs were removed and the mini-implants were removed under reverse torque rotation with a digital torque gauge. Results: 6 weeks after placement, the SLA group presented a higher mean removal torque value (8.29 Ncm) than the smooth group (3.34 Ncm) and histologic analysis revealed a higher new bone formation aspect along the screw in the SLA group. Conclusion: Results of this study indicates that SLA treated mini-implants may endure higher orthodontic forces without loosening.
