The purpose of this study was to serve as a basis for improving the health promotion behavior of adolescents, by examining to what extent middle school students actually had a smoke, in consideration of home, social and school life variables. The subjects in this study were 840 students randomly selected from two middle schools in rural area and three in urban area, North Chung-cheng Province, which included 420 girls and 420 boys. The data were collected for 17 days from June 12 through 30, 2000. And the responses from 799 students were selected for final analysis. The questionnaire used in this study was consisted of 35 items regarding four areas: general characteristics, home variables, social variables and school life variables. The collected data were analyzed with SAS PC + program. The frequency and percentage were employed to find out the general characteristics of the subjects, and x2 test was conducted to determine the relationship of smoking behavior to home, social and school life variables. The findings of this study were as follows : 1. General Characteristics First, as a result of analyzing smoking behavior by grade, gender and place of residence, it' s found that the number of smoker student increased with the advance of grade. Boy students had a smoke, more than girl did. The percentage of smoker student was 75.66% of the boys and 24.34% of the girls. The smoking rate was higher in urban area than in rural one. Second, as a result of investigating when the smoker students started smoking by grade, gender and place of residence, the largest number of them began smoking in elementary school. Third, as a result of analyzing the motivation of smoking by grade, gender and place of residence, their smoking behavior was mostly prompted by curiosity. 2. Family Variable and Smoking Behavior First, the more their family was peaceful, the less they smoked. This factor made a significant difference in smoking behavior.(p<0.001). Second, regarding parental acceptance and parental rejection, the students whose parent had an acception attitude smoked less, and there was a significant difference between the groups(p<0.01). For parental autonomy and control, the students whose parent showed an autonomous attitude smoked less, and the difference between the two was significant(p<0.05). Third, whether or not their fathers smoked didn't give a significant impact on their smoking, but mothers' smoking yielded a significant difference(p<0.05). 3. Social Variable and Smoking Behavior First, those who had more smoker friends smoken more, and the nonsmoker students had no smoker friend or had just one or two. This difference was significant(p<0.001). Second, smoking was affected by time they spent to get together with friends after school, and there was a significant difference in this point between the smoker and nonsmoker groups(p<0.001). Third, 19.74% of the smoker students hung around after school with 6 friends or more, and the rate of the nonsmoker students who got together after school with 6 friends or more was 9.89%. The difference between the two was statistically significant(p<0.001). Fourth, the percentage of having the best friend, among those who had ever been punished in or outside school, was 26.97% of the smokers and 9.87% of the nonsmokers. The disparity between the groups was significant(p<0.001). 4. School Life Variable and Smoking Behavior First, the smokers mostly ranked low in their class, while the nonsmokers ranked high in many cases. This difference was significant(p<0.01). Second, 4.61% of the smokers stayed away from school without due notice three times or more for the last three months, and the same case for the nonsmokers was 0.77%. The difference between the two was significant(p<0.001).

골화석증은 파골세포의 기능 장애 및 증가된 골 밀도를 보이는 질환으로 그 중 유아기형 골화석증은 심각한 유형이다. 전신의 골경화와 범혈구감소증, 두개 신경 협착, 높은 감염위험성, 두부와 안모의 변형 등 다양한 증상을 유발한다. 대부분의 유아기 골화석증 환자는 발달 지연과 왜소증을 보이며, 조기에 사망에 이를 수 있다. 14개월의 여성 환아가 유전치부위에 초기 우식병소를 주소로 전남대학교 치과병원 소아치과에 내원하였다. 환아는 4세에 재 내원 하였으며 interferon-gamma, erythropoietin 치료를 받고 있었다. 성장 지연, 골격 변형, 좁은 상악궁, 총생, 선천적 영구치 결손, 우식증을 보였다. 소아과 의사와 협진하여 예방적 항생제 투여와 진정요법 후 치과 치료를 진행하였다. 이후 감염이 발생한 다수 유구치를 발치 후 상악에 가철성 연성 의치를 이용하여 구강 재건(rehabilitation)을 시행하였다. 골화석증 환자의 경우, 저하된 면역기능으로 인해 감염에 매우 취약하며, 출혈이나 발치와 연관된 골수염이나 패혈증이 유발될 수 있으므로 소아과 의료진의 협조와 예방적 항생제의 사용에 관한 고려가 간단한 치과시술 시에도 필수적이다. 또한, 당분섭취 제한 및 구강위생관리를 위한 의료진의 적극적인 개입이 필요하다. Osteopetrosis is characterized by impaired osteoclast function and increased bone density. Infantile osteopetrosis is a severe form of the disease and has characteristics such as diffusely sclerotic skeleton, pancytopenia, cranial nerve entrapment, infection susceptibility, and abnormal craniofacial appearance. Patients with infantile osteopetrosis often experience developmental delay, and may have a short life span. A 14-month-old girl with osteopetrosis presented to the department of pediatric dentistry. Incipient caries on deciduous incisors were observed. The patient revisited 4 years of age. Besides medical problems, oral complications such as growth retardation, narrow upper arch, crowding, dental caries, and abnormal tooth development were observed. After consultation with her pediatrician, dental treatments were performed on the deciduous molars under sedation after a prophylactic antibiotic injection. At a periodic follow-up, multiple deciduous teeth were treated and extracted, and oralrehabilitation with a removable partial denture was initiated. Patient with osteopetrosis are highly susceptible to infection because of their compromised immune system and problems associated with wound healing that lead to osteomyelitis or sepsis development. Active participation in dental care for sugar intake management and proper oral hygiene are obligatory.

This study aimed to evaluate the nasopharyngeal and oropharyngeal dimensions of the patients with skeletal class II division 1 or division 2 patterns during the pre-peak, peak, and post-peak growth periods for comparison with a skeletal class I control group (79 for pre-peak, 40 for peak, 40 for post-peak). Total 159 lateral cephalograms (70 for skeletal class I, 51 for skeletal class II, division 1, and 38 for skeletal class II, division 2) were selected. The growth of anteroposterior dimension of the pharyngeal airway were statistically significant among growth periods. The dimension for the nasopharyngeal and oropharyngeal airway space was the smallest in the division 1 skeletal class II group followed by class II division 2 and skeletal class I. 본 연구의 목적은 소아 및 청소년의 성장단계별(성장급증기 이전, 성장급증기, 성장급증기 이후) 골격성 II급 1류 및 2류 환자의 비인후 및 구강인후 부위인 상기도부의 기도 폭경을 평가하기 위함이다. 골격성 I급 청소년을 대조군으로 하였다. 전남대학교 치과병원 소아치과에 내원한 소아 및 청소년환자 159명(골격성 I급 70명, 골격성 II급 1류 51명, II급 2류 38명)을 대상으로 하였다. 측모두부 방사선사진과 수완부 방사선사진을 이용하여 성장단계별로 분류하였다(성장급증기 전, 성장급증기, 성장급증기후). 상기도부의 해부학적 폭경을 측정하기 위해서 13개의 계측점, 5개의 계측각, 5개의 계측선, 3개의 비율을 측정하였다. 그 결과, 비인후 및 구강인후 부위의 전후방 폭경은 조사된 모든 그룹에서 성장과 함께 증가하였다. 부정교합에 따른 비인후 기도부위와 상부 구강인후 기도 부위 폭경의 통계적 차이를 밝히지는 못하였으나, 하부 구강인후 기도부의 전후방 폭경은 골격적 II급 부정교합군이 1급 부정교합군보다 더 좁게 나타났다.

GIS DB를 이용한 토지이용 특성 분석- 부산광역시 건물 높이 시뮬레이션을 중심으로 -

천민경,백태경 한국지리정보학회 2023 한국지리정보학회지 Vol.26 No.3

급격한 도시의 발전을 거듭해 갈수록 인구과밀, 공해오염, 도시 위생문제 등이 발생하면서 상충하는 용도 간의 분리 필요성이 대두되고 있다. 이러한 관점에서 도시의 토지이용이 계획적으로 이루어져야 함에는 이견이 없을 것이다. 따라서 토지공간의 제반 활동을 미리 예측하고 계획적으로 세워 토지이용을 합리적으로 구축하여야 한다. 본 연구는 구축된 데이터를 이용하여 부산광역시의 주거지역, 상업지역, 공업지역 용도분포특성 현황을 비교 분석하여 부산광역시 구·군의 용도지역별 건축물 면적 현황, 연면적, 용적률을 파악하였다. 그 결과 용도지역별 면적 중 주거지역의 비율이 51%로 가장 큰 비율을 차지하고 있었으며, 용도지역별 연면적 중 주거지역의 비율이 63%로 가장 큰 비율을 차지하고 있음을 알 수 있었다. 그리고 토지이용구성비만으로 지역특성을 파악할 수 있는 특화계수를 사용하여 분석하였다. 면적의 절댓값을 집계하는 것만으로는 지역 전체의 경향을 파악하기 어렵기 때문에 면적 구성비를 계산하여 비교하였다. 용도지역별 특화계수 중 주거시설을 보면 기장군, 사상구, 사하구, 중구 이외에는 1.0 이상을 나타내고 있다. 상업시설은 기장군, 강서구, 남구, 사상구, 사하구 이외에는 1.0 이상을 공업시설을 보면 강서구(2.5), 기장군(1.22), 사상구(2.06), 사하구(1.64)로 공단분포지역임을 알 수 있다. 이외 업무시설과 문교후생시설은 골고루 분포되어 있음을 알 수 있었다. 용도지역별 각 표고에 따른 건축물 높이 현황과 용도지역별 건축물 높이 시뮬레이션을 통한 토지이용 분석을 실시하였다. 전반적으로 부산시는 80m 이상의 지역이 43% 이상을 차지하고 있어, 용도지역의 분포가 지형적인 조건의 영향으로 표고가 높은 지역에 지정되어 있음을 알 수 있었다. As cities continue to develop rapidly, overcrowding, pollution, and urban sanitation problems arise, and the need to separate conflicting uses is emerging. From this perspective, there is no disagreement that urban land use should be planned. Therefore, all activities in land space must be predicted in advance and planned so that land use can be rationally established. This study used the constructed data to compare and analyze the use distribution characteristics of residential, commercial, and industrial areas in Busan Metropolitan City to identify the building area status, total floor area, and floor area ratio by use zone in districts and counties in Busan Metropolitan City. As a result, it was found that the residential area accounted for the largest proportion of the area by use zone at 51%, and that the residential area accounted for the largest proportion at 63% of the total floor area by use zone. And the analysis was conducted using a specialization coefficient that can identify regional characteristics based on land use composition ratio. Because it is difficult to determine the trend of the entire region just by counting the absolute value of the area, the area composition ratio was calculated and compared. Looking at the residential facilities among the specialization coefficients by use area, it is above 1.0 except for Gijang-gun, Sasang-gu, Saha-gu, and Jung-gu. Commercial facilities are over 1.0 except for Gijang-gun, Gangseo-gu, Nam-gu, Sasang-gu, and Saha-gu. Looking at industrial facilities, you can see that the industrial complex distribution area is Gangseo-gu (2.5), Gijang-gun (1.22), Sasang-gu (2.06), and Saha-gu (1.64). In addition, it was found that business facilities and educational welfare facilities were evenly distributed. Land use analysis was conducted through simulation of the current status of building heights according to each elevation in each use area and the height of buildings in each use area. In general, areas over 80m account for more than 43% of Busan City, showing that the distribution of use areas is designated in areas with high altitude due to the influence of topographical conditions.

As technology has developed and cost for data processing has reduced, big data market has grown bigger. Developed countries such as the United States have constantly invested in big data industry and achieved some remarkable results like improving advertisement effects and getting patents for customer service. Every company aims to achieve long-term survival and profit maximization, but it needs to establish a good strategy, considering current industrial conditions so that it can accomplish its goal in big data industry. However, since domestic big data industry is at its initial stage, local companies lack systematic method to establish competitive strategy. Therefore, this research aims to help local companies diagnose their big data capabilities through a reference model and big data capability assessment system. Big data reference model consists of five maturity levels such as Ad hoc, Repeatable, Defined, Managed and Optimizing and five key dimensions such as Organization, Resources, Infrastructure, People, and Analytics. Big data assessment system is planned based on the reference model's key factors. In the Organization area, there are 4 key diagnosis factors, big data leadership, big data strategy, analytical culture and data governance. In Resource area, there are 3 factors, data management, data integrity and data security/privacy. In Infrastructure area, there are 2 factors, big data platform and data management technology. In People area, there are 3 factors, training, big data skills and business-IT alignment. In Analytics area, there are 2 factors, data analysis and data visualization. These reference model and assessment system would be a useful guideline for local companies.

천민경(Min-kyoung Cheon),김재환(Jae-hwan Kim),최남기(Nam-ki Choi),김선미(Seon-mi Kim) Asia association of Disability and Oral health 2015 International Journal of Disability and Oral Healt Vol.11 No.1

다발성 우식증을 주소로 내원한 7세 1개월의 여자아이가 신경모세포종의 다각적 치료에 따른 치근 형성이상으로 인해 하악 영구절치의 중증도 동요도를 보여 mini-screw를 이용한 레진강선고정을 시행하였다. 이를 통해 동요도의 감소 및 교합안정을 이루었으며, 따라서 하악 영구절치의 치근 형성이상으로 인한 동요도 증가 시 선택적 치료법이 될 수 있을 것이라 생각한다. Neuroblastoma is a common malignant tumor of the sympathetic nervous system in childhood, arises from embryonic neural crest cells. The period of tooth development is matched with peak times of diagnosis and treatment of neuroblastoma. The intensive multimodality treatment including radiotherapy and chemotherapy is used in patients with neuroblastoma has been shown to have late adverse effects and disturbances in dental development like tooth agenesis, microdontia, enamel hypoplasia and short roots. A 8-year old girl had been on medication and radiotherapy for neuroblastoma since she was 15 months old at Department Pediatrics, Chonnam National University Hospital. Oligodontia, microdontia, and short root formation was notable in clinical and radiological examination. Mobility of lower permanent incisor was detected and measured at about degree 2. Resin wire splint using mini-screw implantation on buccal alveolar bone was conducted for maintenance of mandibular incisors and alveolar bone. Excessive mobility has been eliminated and maintained well so far. Further treatment is planned for re-evaluation of mobility, preventing dental caries and regular oral hygiene management. Although we need further evaluation, this treatment could be one of alternative therapy for those who have similar dental anomalies.

천민경 ( Cheon Min-kyoung ) 경기대학교 관광종합연구소 2019 여가관광연구 Vol.31 No.-

본 연구는 군산 시간여행마을을 방문한 관광객을 대상으로 관광스토리텔링과 방문자의 관광목적지에 대한 매력지각, 관광객 행동의사간의 영향관계에 알아보고자 하였다. 현대사회가 빠르게 변화하면서 관광객의 가치관은 변화하고 욕구는 다양해지고 있다. 급변하는 유행에 따라 인기를 얻은 관광지의 모방이 늘어나면서 관광목적지의 차별화가 중요해지고 있다. 따라서 관광지만이 가지고 있는 고유성 즉, 스토리텔링이 점차 중요해지고 있는 것이다. 본 연구를 위해 2018년 10월 13일에서 10월 14일에 걸쳐 군산 시간여행마을을 방문한 관광객 120명으로부터 설문지를 받았다. 설문조사 결과 관광스토리텔링의 구성요인인 흥미성과 교육성이 관광지 매력지각의 신기성에 영향을 미치는 것으로 나타났다. 관광스토리텔링과 행동의사의 영향관계 분석 결과 스토리텔링의 흥미성과 교육성요인은 행동의사에 유의한 영향을 주는 것으로 나타났다. 마지막으로 관광지 매력지각과 행동의사의 영향관계분석 결과 매력지각은 관광객의 행동의사에 영향을 미치는 것으로 나타났다. This study tried to find out the relationship between tourist storytelling, visitor attraction awareness and tourist behavior among tourists who visited Gunsan time travel village. With the rapid change of modern society, tourists' values are changing and their desires are diversifying. Differentiation of tourist destinations is becoming important as imitation of tourist attractions that have gained popularity due to rapidly changing trends. Therefore, the uniqueness of tourism alone, or storytelling, is becoming increasingly important. For this study, we received a questionnaire from 120 tourists who visited Gunsan's time travel village from October 13 to October 14, 2018. The survey found that the interesting and educational nature, a component of tourism storytelling, affects the novelty of tourist attraction perception. Analysis of the influence relationship between tourism storytelling and behavioral history showed that the interest and educational factors of storytelling have a significant effect on behavioral events. Finally, the analysis of the impact relationship between tourist attraction perception and behavioral history shows that attraction awareness affects the behavior of tourists.
