This study is a descriptive survey to explore the health lifestyle of adults. The study subjects are teachers of elementary. middle and high school. and staffs of research institutes located in Chungchung Province and Daejon city. The data was collected from Jan. to march 1997 through self reporte for structured questionnaire. Fantastic check list of Wilson and Ciliska for Health Lifestyle Assessment and DSM-III-R for somatic symptom were used as tools. Data was analysed by frequency, $X^2_test$, t-test and Anova using SAS program. The results are as follows: 1. There were statistically significant differences In drinking(t=7.75, P=.000), exercise(t=-2.99, P=.003)and interpersonal relationship(t=2.22, P=.027) among 10 health lifestyle between smoking group and non-smoking group, in drinking(t=17.98, P=.000), exercise(-4.71. P=.000), and job satisfaction(t=2.22, P=.027) between drinking group and non-drinking group, and in eating habit(t=-2.00, P=.045), drinking (t=4.47, P=000), exercise (t= -16.49, P=000), keeping traffic law(t= -2.68, P=.007), personality (t= -2.05, P=.040) and anxiety/depression(t=-3.47, P=.000) between exercise group and non-exercise group. 2. There was statistically significant difference in cardiovascular symptom(F=4.22, P=.0l) among somatic symptoms of subjects according to exercise level. 3. There was statistically significance difference in lifestyle according to smoking level(F=, 3.33, P=.011), drinking level(F=9.17, P=.0001) and exercise level(F=11.93, P=.000l), and in somatic symptom according to sex(t=-3.93, P=.0001), weight(F=3.83, P=.022), exercise level (F=3.29, P=.03) among general characteristics. 4. There was statistically significant difference between sex in general (t= -3.64, P=.0001), gastrointestinal(t=-2.21, P=.02), musculoskeletal(t=-3.92, P=.001), and total symptom (t= -3.92, P=.0001). 5. There was statistically very highly signigicant difference In weight according to smoking($x^2=25.18,\; P=.001)$ and exercise$(x^2=16.46,\; P=001)$. 6. There was statistically significant difference in frequency between smoking group, drinking group and exercise group$(x^2=24.52,\;P=.001)$. Among a number of habit, smoking, drinking and exercise are important factors of human health to prevent related disease morbidity and death. It is essential for industrial health nurse to committ in this subject considering the influence of those factors and lifestyle on health. There is also a relationship of weight with smoking and exercise, the frequency of overweight/obesiy in smoking/ no-exercise group were high. It is quite necessary for the people having cardiovascular symptom to exercise to lower morbidity and mortality. The industrial health nurse has to keep In mind on this point and consider of time and facilities of fitness of employee. It needs to explore the cause by further research on somatic symptom of women. This research shows that concerning the relationship between smoking, drinking, and exercise, health care provider must take not only management of disease, but health behaviors and lifestyle into consideration.

This is a series of continuing research on facial bone fractures of Koreans worked by Dept. of Oral and Maxillofacial surgery, Dental College of Yonsei University, Seoul, Korea, since 1972. The study was based on a series of 630 patients with facial bone fractures treated as in-patient at Yonsei Medical Center, Yonsei University, during the period of Jan., 1982 through Dec., 1987. The results obtained are as follows: 1. The ratio of Men to Women was 4.3 : 1, and admissions for facial bone fractures have been increased year after 1984. 2. The age frequency was highest in the third decade(38.3%), and fourth, second, fifth decade in orders. 3. The traffic accident was the most frequent cause of facial bone fractures (51.3%). 4. The most common location of facial bone fractures was the Mandible(35.3%), and Zygoma complex(29.8%), Nasal bone(15.0%), Maxilla(11.0%) were next in order of frequency. 5. In 291 patients of Mandible fractures, 226(77.7%) had fractures only in Mandible and 65(22.3%) had another facial bone fractures. The most frequent fracture site of Mandible was the Symphysis(43.0%) and Angle(22.4%), and Simple fracture was the most frequent in type of fracture(66.9%). Intermaxillary fixatin & Open reduction was major method of treatment(36.9%). 6. In 394 patients of Midface fractures 323)82.0%) had fractures only in Midface and 71(18.0%) had another facial bone fractures. The most frequent site of Midface fractures was zygoma complex & zygomatic arch(42.7%), and Simple fracture was the most common type of fractures. Observation(Maxilla :44.2%, Zygoma :51.0%) and Open Reduction(Maxilla :20.0%. Zygoma :23.5%) were the major method of treatment. 7. The frequency of Nasal bone fracture was about 1/5 of Midface fractures, and Closed Reduction(45.2%) was the major method of treatment. 8. The complication was reported in only 16 patients, and Malunion was the major complication. 9. Head(44.4%), Lower extrimities(14.5%) and Eye(12.3%) were injured commonly with facial bone fractures. 10. The elapsed time from injury to hospital was within 24 hours in 73.8% of patients, however 15.5% of patients arrived the hospital 72 hours after injury.

대기오염(大氣汚染)이 비교적 심각(深刻)하다고 생각되는 도시와 농촌과의 호흡기증상을 비교(比較)해 보고자 대구 주민 470명, 포항 364명, 농촌지역인 의성군 주민 472명을 대상(對象)으로 호흡기증상에 대한 설문지를 만들어서 1984년 4월 10일에서 4월 30일까지 각 지역 중 고학생들을 통하여 그들 가족에게 설문하였다. 각 지역에 따른 증상호소율을 볼 때 대체로 도시가 농촌보다 높았는데 특히 ${\ulcorner}$목이 부었다${\lrcorner}$고 느끼거나 ${\ulcorner}$가래${\lrcorner}$, ${\ulcorner}$천식${\lrcorner}$ 증상이 농촌에 비해 도시가 높게 나왔으며(p<0.05), 다만 여자에서 ${\ulcorner}$감기를 심하게 앓는다${\lrcorner}$는 경우는 농촌이 높았다. 연령군(年齡群)에 따라 도시, 농촌을 비교(比較)해 보면 남자 19세 이하군에서 ${\ulcorner}$목이 부었다${\lrcorner}$고 느끼는 경우가 농촌에 비해 포항이 높았으며(p<0.05), 남자 40대에서는 ${\ulcorner}$식은땀${\lrcorner}$, ${\ulcorner}$목의 이물감${\lrcorner}$이 오히려 도시에서 농촌보다 낮게 나타났다. 학생들에게서는 도시, 농촌간의 차가 거의 없었고, 직업인에서 ${\ulcorner}$목이 부었다${\lrcorner}$고 느끼는 예가 포항이 농촌보다 높았으며(p<0.05), ${\ulcorner}$감기${\lrcorner}$, ${\ulcorner}$잔기침${\lrcorner}$은 포항이 농촌보다 낮았다(p<0.05). 이상에서 몇 항목에 대해 농촌이 더 높은 것은 농부(農夫)들의 심한 피로(疲勞)와 농약 등에 의한 것으로 생각되나 전반적(全般的)으로 볼 때 ${\ulcorner}$천식${\lrcorner}$, ${\ulcorner}$가래${\lrcorner}$ 등 도시가 농촌보다 많은 항목에서 호소율이 높았다. 이는 산업연료(産業燃料), 차량(車輛)의 배기(排氣)가스, 먼지 등의 영향이 아닌가 생각된다.

CCTV는 범죄 예방, 공공 안전 강화, 교통 관리 등 다양한 목적으로 사용된다. 그러나 카메라의 범위와 해상도가 향상됨에 따라 영상에서 개인의 신상정보가 노출되는 위험성이 있다. 따라서 영상에서 개인 정보를 보호함과 동시에 개인을 식별할 수 있는 새로운 기술의 필요성이 존재한다. 본 논문에서는 객체 식별 및 추적을 위한 히스토그램 기반 특이값 분해를 제안한다. 제안하는 방법은 객체의 색상 정보를 이용하여 영상에 존재하는 서로 다른 객체를 구분한다. 객체 인식을 위하여 YOLO와 DeepSORT를 이용해 영상에 존재하는 사람을 탐지 및 추출한다. 탐지된 사람의 위치 정보를 이용해 흑백 히스토그램으로 색상 값을 추출한다. 추출한 색상 값 중 유의미한 정보만을 추출하여 사용하기 위해 특이값 분해를 이용한다. 특이값 분해를 이용할 때 결과에서 상위 특이값의 평균을 이용함으로 객체 색상 추출의 정확도를 높인다. 특이값 분해를 이용해 추출한 색상 정보를 다른 영상에 존재하는 색상과 비교하며 서로 다른 영상에 존재하는 동일 인물을 탐지한다. 색상 정보 비교를 위해 유클리드 거리를 이용하며 정확도 평가는 Top-N을 이용한다. 평가 결과 흑백 히스토그램과 특이값 분해를 사용하여 동일 인물을 탐지할 때 최대 100%에서 최소 74%를 기록하였다.

Objectives: This study is aimed at identifying the influential factors on the pulmonary function of ordinary residents in the surrounding areas of Yeosu Industrial Complex. Methods: The PFT (Pulmonary Function Test) was conducted on the target residents numbering 989 people (male 361, female 628). The exposed group (813 people) resided within the radius of 5km from Yeosu Industrial Complex and the control group (176 people) resided in the radius of more than 15 km from May 2007 to November 2007. The survey also took into account other factors including personal characteristics, life habits, respiratory diseases and allergic symptoms, medical histories, and the living environments of the residents in order to further identify influential factors on pulmonary function. Result: When comparing the PFT values of the exposure groups to the control group of the same city, values of the exposure groups were meaningfully lower with an %$FEV_1$ of 107.05% and %FVC of 100.28%. Conversely, the control group reported an %$FEV_1$ and %FVC of 107.26% and 102.85% respectively, indicating that ambient air pollutants reduce lung function. The odds ratio of asthma diagnosis history increased when a subjects residence was close to a heavily trafficked road, traffic amount was huge, a bed was used, and the family had less than four members. However the results were not statistically meaningful. The odds ratios of abnormal pulmonary function were statistically higher among those with asthma(OR=4.29, CI=1.75-10.56), wheezing (OR=2.59, CI=1.24-5.41), and nasal congestion (OR=2.87, CI=1.36-6.08) (p<0.01). The factors affecting $FEV_1$ were symptoms including asthma, passive smoking and allergic eye disease ($R^2$=0.049, p<0.001). For the FVC symptoms including asthma ($R^2$=0.014, p<0.001) were measured. The analysis showed that FVC decreased with increases in $O_3$ and CO(p<0.01). Furthermore, $FEV_1$ decreased with increases in $O_3$(p<0.01). Conclusions: These results will provide preliminary data for establishing responsive measures to protect the health of residents in industrial complexes from air pollution, and to develop lasting environmental health policies.

Stable Compression Fractures(SCF hereafter) are most often caused by trauma such as traffic accidents. These SCFs usually occur in the thoracic and lumbar regions of the spinal cord. Human life spans have increased as a result of medical advances, which in turn has led to an increase in the elderly population. SCFs are divided into the categories of stable and unstable. The categories are determined through X-rays and P/Ex tests. The D.I.T.I. is then used to diagnose the severity and prognosis of the fracture injuries, and it allows an objective evaluation of the symptoms. This author researched 40 patients who were treated at Wonkwang University Oriental Medical Center from October 1995 to December 1996. The patients were diagnosed by X-ray as having SCFs and treated primarily with acupuncture. Both the changes in D.I.T.I. and patients' self-diagnoses of their conditions before and after treatment yielded the meaningful results which have been presented here. 1. 75% of those who suffer from Stable Compression Fractures are 60 years of older. Of those, the ratio of male to female is 1 to 4. This is due in part to the fact that many elderly women seek Oriental medicine treatment for conditions associated with advanced age. 2. 53.3% of these injuries occurred between T11 and L2. 3. 65% of patients were hospitalized for 10 to 29 days, and then able to be treated on an outpatiens basis. 4. The D.I.T.I. results showed 50% below $0.2^{\circ}C$, 30% between 0.3 and $0.5^{\circ}C$, 10% between 0.5 and $0.7^{\circ}C$, 10% between 0.7 and $0.9^{\circ}C$, and 0% over $0.9^{\circ}C$. 5. The results of treatment using Modified Evaluation System in Thoracolumbar Vertebral Fractures Method showed that 55% of patients achieved excellent recovery and 40% achived good recovery. After comparing the D.I.T.I. results before and after treatment, we found 50% of patients showed excellent recovery $({\Delta}T{\leq}0.2)$ and 40% showed good recovery$(0.2<{\Delta}T{\leq}0.5)$.

Objectives: This study aims to identify the influential factors on the pulmonary function of targeted general residents in the areas surrounding Gwangyang Steel Mill. Methods: An PFT (Pulmonary Function Test) was conducted from May 2007 to November 2007 on 974 target residents (438 male, 536 female), including an exposed group (674 people) who resided within a radius of 5 km from Gwangyang Steel Mill in Gwangyang-si, Jeollanam-do and a control group (300 people) who resided outside a radius of 15 km. A survey related to personal characteristics, life habits, respiratory diseases and allergic symptoms, medical histories and living environments of the residents was also conducted to identify influential factors on pulmonary function. Results: As %$FEV_1$ and %FVC of the exposed group are 99.17% and 96.98%, respectively, and those of the control group are 105.47% and 101.91%, respectively, with the PFT values of the exposed group being lower than those of the control group (p<0.001), it turns out that the pollution in the industrial complex is likely to trigger a reduction in the pulmonary function of local residents. The odds ratio analysis result for asthma diagnosis history indicates that the odds ratios tend to be higher among surveyed residents who are living near above-average traffic volumes and are using beds, where it is statistically meaningful that especially the odds ratios are higher if the residences are closer to roads (p<0.01, CI=1.12-4.52). The factors that affect the FEV1 are identified as smoking, passive smoking, asthma diagnosis history, nasal congestion symptoms and allergic eye disease ($R^2$=0.154, p<0.001). The factors that affect the FVC are identified as smoking, passive smoking, asthma diagnosis history and allergic coryza ($R^2$=0.158, p<0.001). In addition, the analysis result for the relevance of air pollution levels to pulmonary function ($FEV_1$, FVC) shows that FEV1 and FVC tend to decrease as the concentration of $O_3$ increases. Conclusions: We believe that this study may provide preliminary data for the development of preventive measures for health effects on the residents and environmental health control measures for environmental pollution in the industrial complex area.
