This study was carried out to investigate food label perception and utilization classified by age and sex. Questionnaires were collected from 938 male and female customers aged in their 20's to 50's from February 4th to March 30th 2014. Regarding checking food labels at the time of purchase, 73.8% of consumers checked food labels, and there was a significant difference by age and sex. Female more often checked food labels than males, and the 40's group showed a higher ratio of checking food labels than other age groups. The main reason for checking food label was 'confirming expiration date' (60%), 'ingredients' (16.4%), and 'nutrition contents' (13.7%). The main reason not checking food labels was 'too small and insufficient to understand' (50.3%), 'too difficult to understand' (16.4%), and 'have no concern' (14.9%). There was a significant difference by age, as in the 50's group showed a higher ratio of 'too small and insufficient to understand' than the other age groups, and 20's and 30's groups showed a higher ratio of 'too difficult to understand'. The overall satisfaction score was 2.96, awareness score was 2.88, and reliability score was 2.93. A total of 96% answered that food labelling education is needed. Therefore, food labelling education for consumers is required to encourage consumers to purchase healthy foods.

연구배경 : 3대 특정질병 진단보험금지급의 양상과 경향을 평가하고자 하였다. 방법 : 1997년 7월${\sim}$1999년 3월까지 당사의 한 건강보험가입자 중 1998년 1월${\sim}$1999년 9월 기간동안 당사 약관상의 정의에 의한 악성종양, 급성심근경색증, 뇌졸중으로 진단보험금이 지불된 총 411건에 대해 조사하였다. 결과 : 3대 특정질병 진단보험금 지급건 총 411건의 구성을 보면 악성종양이 290건(70.6%), 급성심근경색이 25건(6.1%) 그리고 뇌졸중이 96건(23.3%)이었다. 남녀비율은 남자 280건(68.1%), 여자 131건(31.9%)이었다. 3대 특정질병 진단급여금 지급건의 평균연령은 $3.88{\pm}5.9$이었다. 3대 특정질병 진단보험금 지불건은 $30{\sim}39$세 연령대에서 187건(45.4%)으로 가장 많았고, 그 다음으로 $40{\sim}49$세 연령대 178건(43.2%)의 순이었다. 계약시점에서 3대 특정질병 진단보험금 지급 시까지 평균진단확정 기간은 325.2일${\pm}$184.9일 이었다. 계약 후 12개월 내에 진단지급보험금 발생건은 총 193건(55.3%)이었고, 12개월 이후에 지급된 건은 156건(44.7%)이었다. 계약 후 12개월 내에 진단지금보험금 발생건 193건을 분석하여 보면 3개월 이상${\sim}$4개월 미만이 40건(20.7%)로 가장 많았다. 악성종양의 신체계통별로 보면 소화기관>유방>여자생식기>호흡기계 순이었다. 악성종양을 장기별로 보면 위암>유방암>간암 및 담도계암>결장암과 직장암, 자궁경부암의 순이었다. 남자의 경우 위암>간암 및 담도계암>결장암과 직장암의 순이었고 여자의 경우 유방암>자궁경부암(상피내암 제외)>결장암, 직장암의 순이었다. 뇌졸중의 종류별 빈도를 보면 뇌경색증(47.9%)>뇌내출혈(34.4%)>거미막하출혈(9.4%)의 순이었다. 결론 : 3대 특정질병 중 악성종양이 다수를 차지하고 있었고, 남자가 여자보다 훨씬 많았고 주로 $30{\sim}39$세 연령대, $40{\sim}49$세 연령대였다. 계약 후 12개월 내에 진단지급보험금 발생건을 분석하여 보면 3개월 이상${\sim}$4개월 미만이 40건(20.7%)으로 가장 많았다는 것은 역선택의 가능성 그리고 제척기간 중 발생한 3대 특정질환이 3개월 이후 특히 3개월 이상${\sim}$4개월 미만 사이에 지급청구되었을 가능성을 시사하는 것으로 사료된다.

에이즈 감염자 대부분이 $20\~40$대의 노동력이 왕성한 연령대이다. 이들은 에이즈에 대한 사회적 편견과 차별로 인하여 자의반타의반 노동력을 포기하고 있다. 이로 인하여 국내 노동생산성은 급격히 하락하여 국가와 가정 경제를 위협하고 있다.

The purpose of this study is to examine differences between 20s and 40s in visuospatial performance and brain activation areas using functional Magnetic Resonance Imaging (fMRI). Eight male college students in their twenties ($21.5{\pm}2.3$ years old) and six male adults in their forties ($45.7{\pm}2.6$ years old) who were graduated from college participated in the study. A visuospatial task was presented while brain images were acquired by a 3T fMRI system. Compared to the 20s the 40s showed lower visuospatial performance. There were more activations observed at the parietal and superior frontal areas at 20s compared to 40s. There were more activations observed at the middle frontal and occipital areas at 40s compared to 20s. The results of this study show that the lowering of visuospatial performance with aging was correlated to the decrease of activation area at the parietal lobe and the change of activation area at the frontal lobe.

20대 여성 CEO, 남편인 CTO 이영일(29)이사와 Company Couple, 성공적인 해외진출, 모바일게임 50여종개발 등 화제의 주인공으로 주목받은 사람은 모바일게임업체 컴투스의 박지영 사장이다. 2000년 초반 벤처붐과 함께 20대 스타 CEO가 여럿 등장했지만, 경제위기의 파고를 넘은 사람은 별로 눈에 띄지 않는다. 그런 가운데 모바일 게임으로 국내시장은 물론 해외시장 개척까지 성공하며 승승장구하고 있는 컴투스의 성공이 더욱 값지게 느껴지는 것 같다.

This study is to investigate the effects of the physical activity and intake of improved food levels on male body compositions. Forty men were assigned to a percentage of body fat (PBF) group (20 men with physical exercise and food) and CONTROL group (20 men with exercise, food intake is free) for this six-month study. An aerobic capacity test to measure maximum oxygen consumption ($VO_2$ max) was performed to precisely determine the exercise intensities during the experimental conditions. After exercise and food control, the body weight of 20s with exercise and food (A) and only exercise (B) decreased about 2.3 kg and 0.4 kg after 6 months, respectively. If the p-values were 0.697(between baseline and 3 months), 0.535(between 3 months and 6 months), and 0.617(between baseline and 6 months), respectively, then 20s men had evidence of that a significant main effect does not exist amongst the observations of the outcome or within-weights. Their skeletal muscle mass (SMM) of both groups increased slightly through exercise. Although the decrease in total body weight of 30s was correlated with the increase in SMM, there was not shown significant. While total body water decreased in 20s, 40s, and 50s except 30s men, all other values did not shown significant differences. The physical activity and intake of improved food levels were contributed with lost a lot of weight, decrease of SMM and body fat.

This study tried to compare and analyze the body measurements of female adults in China by various age groups. As for the study method, direct and anthropometric measurements were used on the 357 female subjects living in Yenbien and Harbin, China, consisting of 122 women in their 20's, 114 women in their 40's, and 121 women in their 60's. The results were as follows: 1. The comparison of major body measurements between Korean Chinese and Korean in land indicated that the former were shorter and plumper than the latter. Those groups in their 60's did not show any significant difference in height related measurements and revealed less differences in body measurements comparing to other age groups. 2 The comparison of Chinese anthropometric measurements among age groups of Korean Chinese indicated that, higher the age, shorter the height measurements, the leg length shorter, the upper-half body length longer, and the chest drooping due to the breast descent. 3. The comparison of indirect measurements among age groups of Koreans Chinese indicated that those in their 60's showed many items of big discrepancies in comparison with those in their 20's or 40's, with wide gap in discrepancies, thus resulting in large differences among individuals.

It is well known that Korea is one of the endemic area for type B viral hepatitis. A screening test for HBsAg by RPHA method was performed to evaluate the prevalence of HBsAg among urban, rural and coastal area population during the period between Jan. 1985 and Aug. 1985. The results obtained are as follows; 1) The HBsAg was detected in 242 among 2,849 with positive rate of 8.49%. The positive rate by sex showed higher rate in males(9.07%) than females(6.79%) for HBsAg. But these differences by sen were not statistically significant. 2) By living area, the positivity of HBsAg was 8.67% in urban, 7.43% in rural and 8.37% in coastal area. But the differences were not statistically significant. 3) The positivity differences of HBsAg were significantly observed between male(9.26%) and female(6.44%) in urban area. But there was not in rural and coastal area. 4) The positivity was the highest in 4th decade in urban area. But 6th decade in rural and 4th and 5th decade in coastal area. Generally the positivity of HBsAg was more prevalent in young age and decreasing by the age increasing in the male. But in the female it was most common in 6th decade. 5) Elevated SGOT(>40 Unit) was significantly higher in HBsAg positive group(13.6%) than in HBsAg negative group(3.4%).

자궁근종은 우리나라 여성의 약 40%에서 발견되는 질환 중 하나다. 국민건강보험공단 건강보험정책연구원 자료에 따르면 과거 5년 사이 자궁근종 환자가 20% 이상 크게 늘어난 것으로 분석되었다. 자궁근종 진료인원은 2005년 19만 5,000명에서 2009년 23만 7,000명으로 매년 증가하고 있는 것으로 나타났고 2009년 실 진료비는 999억 원에 달했다. 이 중 20~30대 가임기 여성들의 환자 수가 계속해서 증가하는 추세이며, 30~40대 환자의 비율은 70%에 달해 여성들의 자궁근종에 대한 관심이 날로 높이지고 있다.
