Objectives : We wanted to identify those factors associated with stomach, colon, breast and cervix cancer screening. Methods : A population-based telephone survey was conducted for 2 weeks (the 9th-23th of July, 2004) by trained interviewers with using a questionnaire. 2,598 respondents (females aged 30 years or over, and the males aged 40 years or over) were selected by random-digit dialing that was based on the 2000 Population and Housing Census. The data on socio-demographic, health behavior and enabling factors were collected. 2,571 respondents were included in analysis. The cancer screening rate was classified into 2 categories : the life time screening rate and the screening rate with recommendations. Results : For the 2,571 respondent s, the life time screening rate was as follows: 52.0% (Stomach), 25.3% (Colon), 55.9% (Breast) and 76.8% (Cervix). The screening rate with recommendation was as follows : 3 9.2% (Stomach), 20.6% (Colon), 42.5% (Breast) and 58.3% (Cervix). On a multiple logistic regression analysis of the life time screening, statistically significant relationships were observed for the screening intention, the health exam, the disease history, the age of the patients and the cancer screening rates. On a multiple logistic regression analysis of the screening with recommendation, statistically significant relationships were observed for the screening intention, the health exam, the age of the patients, the concern about the risk of cancer, the voluntary health insurance for cancer and the cancer screening rates. Conclusions : The results of this study suggest that the cancer screening intention, the health exam and the age of the patients are the most important factors to participate in life time cancer screening and also screening with recommendations. A positive association was also observed for the concern about the risk of cancer, the voluntary health insurance for cancer. It is hoped that this study will be a base line data for suggesting the representative cancer screening rate in Korea.

최근 인공지능 모델을 이용한 얼굴인식, 얼굴 수정 등 다양한 얼굴 작업들이 실생활에도 광범위하게 사용되고 있다. 그러나 모델의 학습에 사용되는 대부분의 얼굴 데이터셋은 사회활동이 활발한 특정 나이에 편중되고, 어린아이나 노인의 데이터가 적은 경향이 있다. 이와 같은 데이터셋 불균형 문제는 모델의 학습에도 좋지 않은 영향을 끼쳐, 아이나 노인같이 데이터가 적은 나이의 사람이 인공지능 모델을 사용할 때 사회활동이 활발한 나이의 사람이 사용할 때보다 성능이 떨어질 수 있고, 이들의 인공지능 모델 사용을 어렵게 할 가능성이 높다. 이를 개선하기 위해 본 논문은 특징 분해를 활용하여 얼굴 영상으로부터 나이를 분류하고 목표 나이로 합성하는 기법을 제안한다. 제안하는 기법은 FFHQ-Aging 데이터셋을 이용한 정량적, 정성적 평가를 통해 기존의 방법보다 더 나은 성능을 보인다.

본 연구는 대전 스카이로드 미디어 파사드의 공공 디자인 평가와 감성 평가의 특성을 살펴보고자 하였다. 이를 위해, 대전 스카이로드 미디어 파사드 영상물을 시청하여 대상자들이 미디어 파사드의 공공 디자인 평가 항목과 감성 어휘로 구성된 감성 평가 항목에 응답하도록 하였다. 그리고 인구통계학적 변인에 따른 대전 스카이로드 미디어 파사드의 공공 디자인 평가 결과의 평균 비교를 진행하고, 감성 어휘의 요인 구조를 도출하여 각 요인에 포함되는 감성 어휘를 바탕으로 공공 디자인 평가 요인과의 상관분석을 진행하였다. 그 결과, 대상자들의 성별, 미디어 파사드 경험 여부, 연령에 따라 일부 차이 및 경향성을 보이는 공공 디자인 평가 항목이 존재하는 것으로 나타났다. 한편, 감성 어휘의 요인 구조로는 총 14개의 어휘가 4개의 요인 구조로 구성되었으며, 모든 공공 디자인 평가 요인에 걸쳐 공통으로 관련성이 높은 감성 어휘로는 "쾌적한-불쾌한"이 존재하는 것으로 나타났다. 이는 주관적으로 쾌적하다고 인식되는 감성이 공공디자인으로서 대전 스카이로드 미디어 파사드의 주된 가치로 평가될 수 있음을 시사한다. 다만, 성별과 연령을 고려한 정책이 반영되어 대전 스카이로드가 운영된다면 공공 디자인으로서의 가치가 더 향상될 수 있을 것으로 기대된다.

The differentiation and development of preadipocyte into mature adipocyte are regulated by transcription factors, such as CCAAT enhancer binding protein (Cebp) gene family and sterol regulatory element binding transcription factor 1 (Srebp1). Steroid hormones give influences on the development and function of adipocyte. The present research examined expression patterns of CCAAT enhancer binding protein alpha (Cebpa), CCAAT enhancer binding protein beta (Cebpb), CCAAT enhancer binding protein gamma (Cebpg), sterol regulatory element binding transcription factor 1 (Srebp1), androgen receptor (Ar), and estrogen receptors (Esr) among different epididymal fat parts during postnatal period by quantitative real-time polymerase chain reaction. In the distal epididymal fat, expression of Cebpa, Cebpb, Cebpg, Srebp1, Ar, and Esr2 was increased until 12 months of age, while expression of Esr1 was decreased at 5 months of age and was not detectable after 8 months of age. In the proximal epididymal fat, transcript levels of Cebps and Srebp1 were increased at 8 months of age, followed by decreases of Cebpb and Cebpg transcript levels at 12 months of age. An additional increase of Srebp1 expression was observed at 12 months of age. Expression of Ar and Esr2 were increased until 8 months of age, followed by a drop of Ar expression level at 12 months of age. Expression pattern of Esr1 was similar to that in the distal epididymal fat. In the tail epididymal fat, expression of Cebpa, Cebpg, Srebp1, Ar, and Esr2 was increased with age. Esr1 was not detectable at all. The highest level of Cebpb was observed at 8 months of age. These data suggest the possibility of developmental and functional differentiation among the epididymal fat parts.

Purpose: This study was performed to determine the relationship between the stage of tooth eruption (both vertical and mesio-angular) and chronological age. Materials and Methods: Indirect digital panoramic radiographs were used to measure the distances from the dentinoenamel junction (DEJ) of the second molars to the occlusal plane of the second molar teeth and of the adjacent third molars in 264 Thai males and 437 Thai females using ImageJ software. The ratio of those distances was calculated by patient age, and the correlation coefficient of the ratio of the third molar length to the second molar length was calculated. Results: The correlation between the height of the vertically erupted upper third molar teeth and age was at the intermediate level. The age range of ${\geq}15$ to <16 years was noted to be the range in which the correlation between the chronological age determined from the eruptional height and actual chronological age was statistically significant. The mean age of the female subjects, in which the position of the right upper third molar teeth was at or above the DEJ of the adjacent second molar but below one half of its coronal height was $19.9{\pm}2.6$ years. That for the left side was $20.2{\pm}2.7$ years. The mean ages of the male subjects were $20.1{\pm}3.3$ years and $19.8{\pm}2.7$ years for the right and left sides, respectively. Conclusion: It might be possible to predict chronological age from the eruption height of the wisdom teeth.

Objectives: The purpose of this study is to compare postpartum symptoms of 528 women by age groups and delivery method through health questionnaires of postpartum care center. Methods: From January 2018 to December 2018, we statistically compared the 528 women's postpartal symptoms who divided into 4 age groups using SPSS Statistics 21.0 program. Results: There were no differences in weight changes, gestational age and degree of subjective discomfort by age (p>.05). On the other hand, parity, fetal weight and delivery method were statistically associated with age (p<.05). Especially the rate of cesarean delivery was increased with age. Degree of feeling dyspepsia and edema was higher in cesarean section delivery group (p<.05). Also, as the weight increased by 1 kg during pregnancy, the degree of feeling postnatal edema increased by 0.204 (β=0.204, t=4.204, p<.05). Conclusion: This study showed that age itself will not affect postpartum symptoms alone. Instead it is necessary to consider post-cesarean delivery symptoms for advanced maternal age.

To evaluate the periodontal status of Korean adults, 3,988 adults(20-69 years old) who lived in Kwangju, Chonnam, Taegu, and Kyungbuk districts were periodontally examined by plaque index(PI), calculus index(CI), gingival index(GI), periodontal disease index (PDI), and papillary bleeding index(PBI). The periodontal examination charts were grouped according to age and sex. And subsequently 200 periodontal examination charts in each age group were randomly selected according to sex. The differences of the indices among age groups and those between male and female in each age group were statistically analyzed by Chi-Square test. In PI, CI, GI, PDI, and PBI, there was no statistical significance in the difference between male and female in each age group(p>0.05). In male, PI of 60s age group($1.44{\pm}0.68$) was significantly higher than that of any age group(p<0.05), and in female PI of 20s age group($0.86{\pm}0.39$) was significantly lower than that of any other age group(p<0.05). CI of 60s age group in both male($1.67{\pm}0.70$) and female($1.63{\pm}0.91$) was significantly higher than that of any age group(p<0.05). GI of 20s age group in both male($0.85{\pm}0.66$) and female($0.67{\pm}0.60$) was significantly lower and GI of 60s age group in both male($1.37{\pm}0.60$) and female($1.44{\pm}0.84$) was higher than that of any age group(p<0.05). PDI in male was the lowest in 20s age group($0.70{\pm}0.73$), and was the highest in 60s age group($4.93{\pm}1.96$) (p<0.05). In female PDI of 20s age group($0.71{\pm}0.74$) was significantly lower than that of any age group(p<0.05). In male PBI of 20s age group($0.38{\pm}0.31$) was significantly lower than that of any age group(p<0.001). PBI in female was the lowest in 20s age group($0.35{\pm}0.30$) (p<0.001), and was the highest in 60s age group($1.09{\pm}0.76$) (p<0.05). The data insist that all the young populations of 20s age group should be interested in routine check for early diagnosis and prevention of periodontal disease, and a special education program of periodontal health care for young generation must be prepared, and the periodic recall check system for periodontal examination of middle age group must be supported by government.

It is necessary to compare the dietary characteristics among different age groups because different nutritional problems require different dietary applications. This study was performed to identify the nutritional characteristics of Korean diet among different age groups. The study subjects consisted of preschool children(PC), elementary school children(EC), high school students(HS), college students(CS), and adults over 30 years old living in Seoul and the surrounding areas. The subjects over 30 years old were classified to 30-49 years, 50-69 years, and over 70 years. A dietary survey was conducted using 24-hour recall method and data were collected from 2392 subjects. Energy intake was as much as 1771kcal for PC, 2139kcal for EC, 2475kcal for HS, 2276kcal for CS, 1860kcal for 30-49 years, 1715kcal for 50-69 years, 1326kcal for over 70 years. The subjects of PC, EC, HS, and CS groups got about 25% of energy from fat, but the subjects in 30-49 years, 16%, those in 50-69 years, 15%, and those over 70 years, 13%. The energy consumption from protein was about 15% in each age group. Percent of energy intake as Korean RDA was greater than 100% for PC, EC, HS, and male CS groups. The percent intake for RDA of calcium, iron, vitamin A, and vitamin B$_2$was low in most age group. Iron intake was inadequate in female of PC and CS groups, and subjects in 30-49 years and over 70 years. Mean adequacy ratio(MAR) was 0.9 in PC, and decreased with increase of age. Therefore MAR did not reach to 0.7 among subjects over 70 years. Index of nutritional quality(INQ) for calcium, iron, vitamin A, and vitamin B was below 1 in most age groups. From these results, major nutritional problems of each age group were overall inadequate intakes of calcium and iron, excess consumption of protein and fat for PC, EC, HS, and CS groups, and inadequate nutrients intake of subjects over 70 years old. According to these results, each age group seems to need specific nutritional intervention. (Korean J Nutrition 34(5) : 554~567, 2001)
