With the increase of senior population, adults in their manhood and senescence with neurogenic defects also increase as well; thus, it is necessary to conduct foundational research on speech fluency to rehabilitate adults with neurogenic language disorders. Thereupon, this study analyzes the characteristics of speech fluency comparatively by age and sex with the subjects of normal adults in their 50's to 70's. According to the result of collecting language samples from total 90 adults, 30 (15 males, 15 females) in each age group of the 50's, 60's, and 70's and comparing the speech rate and disfluency frequency, first, adults in their 70's showed slower speech rate than those in their 50's or 60's. And those in their 50's, 60's, and 70's indicated no difference in their speech rate by sex. Second, there was no difference in normal disfluency and total disfluency among the adults in the 50's, 60's, and 70's. Also, there was no difference among the age groups by sex, either. Third, there was no correlation between speech rate of all the age groups and disfluency frequency.

The purpose of the study was to provide basic data for planning and offering nursing intervention to prevent suicide attempts by identifying the factors influencing the suicidal thoughts of depressed adults. The subjects of this study were 1,202 individuals who answered clearly in 2013-2015 National Health and Nutrition Survey. A composite sample plan file was generated using the IBM SPSS 23.0 program, and then the data were weighted and analyzed. Suicidal ideation was influenced by income (50-60s), number of family members (50-60s), marital status (40-50s), subjective health (30-50s, over 70s), stress (30s, over 50s), economic activity status (50s), diabetes (60s or older), alcohol consumption (60s), and Body Mass Index (BMI) (40s). These results suggest that tailor-made interventions for the prevention of suicide need to take into account the general and health-related factors of the subjects.

현재 국내에서 PSC 거더의 제작은 주로 포스트텐션방식을 사용하고 있다. 포스트텐션방식은 콘크리트 양생 후 긴장력을 도입하여 제작회전율이 높은 특성을 가지나 쉬스, 그라우팅, 정착장치 등이 요구되어 조립과정이 복잡하고 제작단가가 높다. 교량에 적용되는 PSC 거더를 포스트텐션방식 대신에 프리텐션방식으로 제작한다면 제작단가를 대폭 감소시킬 수 있을 것이나, 교량용 PSC 거더의 길이가 일반적으로 30~50m이므로 공장에서 제작하여 현장으로 운반하는 것은 운반비용의 상승 및 운반 가능한 크기의 제한을 받게 된다. 운반의 문제를 해결하기 위해서는 현장에서 PSC 거더를 제작하여야 하는데 현장에 긴장대를 고정식으로 설치하는 것은 제작단가의 상승으로 이어져 경제성을 잃게 된다. 따라서 현장에서 사용할 수 있도록 이동식 긴장대를 제작한다면 경제성을 갖춘 프리텐션방식의 PSC 거더 생산이 가능할 것이다. 50m급 이동식 긴장대에는 약 10MN에 이르는 매우 큰 긴장력이 가해져 이동식 긴장대가 콘크리트 양생전까지 이 긴장력을 저항하여야 한다. 본 논문에서는 유한요소 해석프로그램인 ABAQUS를 사용하여 50m급 PSC 거더를 생산할 수 있는 이동식 긴장대를 모델링하여 약 10MN에 이르는 긴장력이 가해질 때에 이동식 긴장대의 각 구성요소의 거동특성 및 하중에 대한 안전성 및 좌굴에 대한 안정성 확보 여부를 해석적으로 파악하고자 한다. 이동식 긴장대는 구성요소인 정착블럭(긴장BOX)과 중간연결블럭으로 나누어 모델링하였다. 정착블럭(긴장BOX)은 다수의 강판을 4절점 쉘요소(S4R)를 사용하여 직육면체의 BOX 형상에 내부를 보강한 단면으로 구성하였고, 중간연결블럭은 H형강 2개를 일체화한 긴장대 거더와 콘크리트 바닥판 블록이 볼트로 합성된 구조이며, H형강은 4절점 쉘요소(S4R), 바닥판블럭은 8절점솔리드요소(C3D8R)를 사용하였다. 긴장대거더와 바닥판블럭은 합성거동을 하도록 weld option을 사용하여 부분적으로 결합하였다. 정적해석결과 이동식 긴장대에 발생하는 응력은 도로교 설계기준에 SS400 강재의 허용응력 140MPa 보다 작으며 선형탄성좌굴 해석결과 가력하중의 2.22배 약 21MN의 하중이 가력되어야 전체좌굴이 발생하게 될 것으로 추정된다. 해석결과를 보아 50m급 PSC 거더를 생산할 수 있는 이동식 긴장대는 하중에 대한 안전성 및 좌굴에 대한 안정성을 확보하고 있는 것으로 판단된다.

We analyzed 121 age estimation clients who had visited oral medicine clinic, Chonbuk National University Hospital, from January 2000 to December 2007 to evaluate its characters in Jeonllabuk-do. The obtained results were as follows : 1. There was distinct difference in sex distribution(Male : 58.7%, Female : 41.3%) and more than half percent(55.4%) was over 50's. 2. The difference between registered and alleged age was the most in more than 5 years, and most of them were over 50's. 3. There were more clients who wanted to increase their age than to decrease and was no prominent difference in sex. Age estimation clients who wanted to decrease their age were predominant under 10 years old and in 20's, and those wanted to increase were predominant in 10's and over 30's. 4. The most reasons to correct age were related to welfare benefit. The purpose of age estimation was different according to each age groups; welfare benefit was the most over 50's, occupation in 40's and 50's, friendship in 30's and 40's, sibling-related in 50's, employment in 10's and 20's. 5. Age was estimated by the attrition of permanent tooth and pulp/tooth ratio from 20 years, root apex closure for 10's and calcification of permanent tooth under 10 years old. In cases that were difficult to estimate by use of the attrition of permanent tooth and pulp/tooth ratio, age was estimated by missing time of permanent tooth and the change of mandibular angle with age. 6. The estimated ages were close to alleged age in 77.7% of clients but the rest(22.3%) was close to registered age.

현재까지의 컴퓨터그래픽스 기술은 물체의 시각적 표현에만 집중되어 왔다고 할 수 있다. 그러나 컴퓨터그래픽스 기술의 발전으로 앞으로는 3차원 데이터가 단지 표현에만 그치지 않고 모든 분야에서의 물체 해석과 예측 시뮬레이션 정보처리에서 활용되어 갈 것이다. 본 논문에서는 3차원 얼굴 데이터를 이용하여 사람의 나이에 따른 얼굴의 변화를 시뮬레이션한 결과를 소개한다. 20대, 30대, 40대, 50대의 3차원 얼굴 데이터로부터 60대의 얼굴을 예측하는 방법을 소개한다. 동일한 인물의 20대부터 50대까지의 실제 얼굴 데이터를 얻는 것은 어려운 일이므로 본 연구에서는 20대의 얼굴데이터만을 가지고 50대까지의 얼굴을 추측하여 생성한 후에 60대의 얼굴을 예측하는 방법을 제공한다.

This study initiated with the intention to reveal the social consultations and fissures through a comparative analysis on generational characteristics by indicating occupation-related identities with the concept of social identity supported by theoretical resources. According to the three dimensions of social identity which are evaluation, potency and activity, there was more generational agreement rather than difference toward occupation-related identities. Among the 44 identities, only evaluation dimensions on minister, congressman, plane captain, farmer and potency dimensions on CEO of a major companies, professor, medical doctor, nurse, celebrity, shaman, unemployed person were statistically significant. For 'Leader and Professional', the respondents in their 50's gave high scores in both evaluation and potency dimensions. On the other side, the 30's had negative viewpoints while the 20's and 40's had neutral perspectives. For the potency dimension, the age groups were divided into the 20's, 30's and 40's, 50's; having the younger generations underestimate the potency dimension of such categories. Also for the 'General Occupation', 20's and the 30's relatively devaluated with more distinctive degree toward evaluation dimensions. For religion, 20's and 30's were positive toward buddhist monks while the 40's and 50's were more favorable with priests. For the non-economically active population, the lifetime cycle influenced each generations. When performing a two dimensional analysis toward the 'Leader and Professional' with evaluation and potency on each axis, the 50's highly evaluated both evaluation and potency dimension of such identities. However, for the 40's, 30's and 20's, the average value fell while the focus of the distribution deepened. The 30's had negative perspective toward the evaluation dimension while the 20's reflected critical attitude toward the potency dimension.

We have studied on the accommodation of people for 10~60ages at Honam residents and compared with the already known accommodation from age. Using Push-up method, we obtained results that average accommodation of each cases were 10ages 9.88D, 20ages 8.65D, 30ages 6.92D, 40ages 5.05D, 50ages 4.29D, 60ages 4.63D. Accommodation was on the decreased in increasing the ages but showed the very high accommodation in 50, 60ages on this study. We judged we should consider a accommodation research of other districts and near addition test.
