Age-related changes in the lens capsule and epithelium of cataractous patients, ranging from 20 to 7o years old, were studied by means or LM, immunohistochemistry, and TEM. The lens capsule was divided into four zones; the anterior, subanterior, middle, and basal zone. The van Gieson staining reaction for collagen was prominent at the anterior and subanterior parts of the lens capsule. The reaction was more decreased in the elder group than the younger group. The collagen type IV reaction was prominent at the anterior zone of the lens capsule and around the cell. The reaction was more decreased in the elder group than the younger group. 3. The Periodic Acid Shiff-Alcian Blue reaction for mucopolysaccharide was prominent at the anterior zone of the lens capsule. The reaction was more decreased in the elder group than the younger group. The Apoptotic reaction was prominent at the nucleus of the lens epithelial cell. In the elder the cataractous group, the number of the apoptotic cells was more decreased. The electron microscopic change of lens epithelial cells were characterized by the increase of lateral fold and the cytoplasm with various vacuoles and Golgi complex. In the basal part, lens epithelial cell protruded toward the lens capsule in the 20-year-old group. The basal part of the 40-year-old group was flattened and covered with the cytoplasmic processes of adjacent cells. In the 60-year-old group, the mass of rough filaments separated lens capsule and the basal part of the lens epithelial cell. The electron microscopic change of the middle part of lens capsule was characterized by the aggregation of electron dense materials in the 40-year-old group, and the appearance of filamentous materials and the decrease of electron dense granules in the 60-year-old group.

As a means to get a better understanding of the kind of form changes to which is subject the neck of the men, in its aging process, several measurement recordings on a vertical and horizontal sections were carried. Subjects were young, middle aged and elder men (15 in their twenties, 11 in their forties and again 11 in their sixties) 1) The analysis of the meansurement results led us to distinguish 3 types of subjects according to the position of the their Adam's apple with regard to the horizontal plane containing their 7th cervical vertebrae point : clearly above (Type I), next to(Type II), clearly below(Type III). We found that young men correspond to the Type I and II, middle aged men to the Type ll and 111 and elder men only to the Type III. 2) The comparison of the horizontal sectional surface contained in the planes corresponding to the 4 points, shows a larger sectional surface for elder men in the Adam's apple plane, accompanied by a change of position of the Adam's apple forwards. As for the front neck point plane, the body sectiolial surface is larger in depth in elder men, without much change in breadth. And for the acromion point plane, we observed also an increase in depth, but with a decrease in breadth corresponding partially to the atrophy of the thoraric cage in eldermen.

The main purposes of this study are to describe the elderly dementia, and to explore characteristics of the elderly dementia among the aged 65 and over in Daegu area. In this study, 1,120 subjects which were 0.6 percent of the population were selected and face-to-face interviews were conducted. The face-to-face interviews were conducted from July 1, 2004 to August 31, 2004. KMMSE was introduced to measure the status of the interviewees' dementia. The findings of this study are as follows: 8.9 percent of respondents turns out to be dementia patients. Among the dementia patients, 52.5 percent are mild dementia patients, 35.0 percent are mid-level symptoms and 12.5 percent are severe symptoms of dementia patients. Cross-tabulation analyses and logistic regression analysis were introduced to explore the demographic, living, and behavioral differentials of the elderly's dementia. According to the logistic regression analysis, it turns out that white educational attainment, participating in the leisure activities for both physical exercise and mental activities, having meals regularly, adequate amount of meals, and high economic status decrease the odds ratio of elder dementia among the elderly who are 65 and above in Daegu area and are statistically significant. On the other hand, age increases the odds ratio of the elder dementia of the elder among Koreans above 65 in Daegu area. Finally, policy implications and some suggestions for the improvement of the elder dementia are introduced and discussed.

It is hardly surprising for the current elder generation to choose extreme measure, that is to commit suicide, because of various social or health problems caused by financial difficulties and diseases, for neither individuals nor the nation had not prepared for their later lives. Therefore, the number of elder suicide is rapidly increasing, so that it is becoming a big social issue. Research in various fields related to elderly suicide has been done due to recent huge interest, but most of them focused on microscopic factors and it is likely that most are in national level or individual level, so research about elderly suicide by regional areas is insufficient. Due to the nature of Korean administration system which is operated by each local government, study on elderly suicide by regional areas is acutely required. The purpose of this study is to draw policy suggestions of preventing suicide by analyzing current state of suicide rates in terms of sex(male elder vs female elder) and age(young old vs old old) in each 16 regions for 9years(from 2003 to 2011) and then analyzing interrelationships between the suicide rates and socio-economic factors.

Objectives : This research was conducted to investigate geriatric care workers' oral care, and the oral care conditions of residents of elder care facilities in relation to workers' knowledge of oral care. Methods : A survey was conducted from November 2011 to February 2012 with geriatric-care workers in elder care facilities located in Busan and other areas of Gyeongsangnam-do. Results : With regard to their oral self-care practices, 52.5% of the geriatric workers "brushed their teeth from top to bottom" and 58.1% brushed their teeth 3 times a day. Further, 52.0% did not use any oral care products, while 36.5% used Mouthrinese. The workers who brushed their teeth in their own ways or from top to bottom had significantly higher oral care knowledge scores than those who brushed from left to right (p<.05). Concerning oral hygiene care for residents, 72.6% of the geriatric workers recommended that elders visit dentists for oral care, 96.6% helped elders oral wash their teeth every day, and 54.7% used oral care products for the elders. The workers who did not recommend visits to dental clinics scored slightly higher than those who did (p<.05). Additionally, those who did not help elders oral wash their teeth scored significantly higher than those who did (p<.05). Except for oral wash to recuperated old man and recommendation of visiting the dentist, relation between oral care and knowledge about oral health and oral hygiene care is plus mutual relation. Conclusions : To manage the accuracy and quality of oral care work performed by geriatric care workers in elder care facilities, enhancing standard training and education on oral care is necessary. Providing systematic, regular education on such knowledge and practices would also be essential.

하천 내 오염물질 유입원은 하수처리장과 같이 농도를 예측 가능한 점오염원이 일반적이지만, 수질오염사고와 같이 다량의 유해물질이 일시에 하천에 유입되는 경우도 발생하곤 한다. 특히 오염물질 유입지점과 취수장이 인접한 경우, 오염물질 혼합해석에 대한 이해가 오염사고 대응 및 수질 관리 측면에서 매우 중요하다. 자연하천에서는 사행에 따른 유속 구조의 불균일성 등으로 인하여 오염물질의 이송 및 분산 과정은 매우 복잡하게 나타난다. 이러한 하천의 지형적, 수리학적 특성이 오염물질의 혼합 거동에 미치는 영향을 정확하게 모의하기 위해서는 3차원 수치모형을 적용해야 한다. 그러나 대부분의 하천은 하폭 대 수심비가 매우 크기 때문에 2차원 이송-분산 방정식을 지배방정식으로 채택하는 2차원 수치 모형이 널리 사용되어왔다. 2차원 이송-분산 방정식의 해석결과는 입력된 종, 횡 분산계수의 값에 따라 변화하기 때문에 정확한 혼합해석을 위해 분산계수의 결정이 매우 중요하다. 과거 연구에서는 횡 분산계수의 결정을 위해 기본 수리량을 이용한 경험식을 활용하여 계산한 바 있다. 종 분산계수의 경우에는 경험식의 산정에 필요한 충분한 실험 자료가 축적되어 있지 않아 이상적 흐름 상태를 가정하여 유도된 Elder의 이론식(Elder, 1959)을 사용해왔다. 하지만 많은 연구에서 이러한 Elder의 이론식이 종 분산계수를 과소산정 할 우려가 있다고 제시했다. 따라서 하천의 전단류 분산특성을 나타낼 수 있는 데이터 확보를 통해 종 분산계수의 경험식 산정 및 횡 분산계수의 정확도 향상이 필요한 상황이다. 본 연구에서는 기존 선행 연구에서 수행된 2차원 추적자실험 데이터의 확장을 위해 오버샘플링 기법을 적용하였으며, 이를 통한 머신러닝을 통한 분산계수 산정 가능성을 분석하고자 한다. 부족한 추적자 실험 데이터를 확장하기 위해 오버샘플링 기법 중 SMOTE 기법을 활용했다. 오버샘플링 기법을 이용하여 생산된 데이터의 신뢰성을 검증하였으며, 추후 머신러닝을 이용한 2차원 종, 횡 분산계수 산정에 대한 활용 가능성을 분석했다.

Purpose: The purpose of this study is to analyze the elderly friendliness of the serious game for dementia prevention and to seek out the influence factors for enhance the friendliness. Research design, data and methodology: It measured the elderly friendliness of the serious game for dementia prevention, run with multi-touchscreens, for 300 elderly people using the Seoul-based General Social welfare centers located at Seoul, and participants evaluated the elder-friendliness of the serious game, by responding to a questionnaire survey. In addition, it analyzed the influence relationship between the elderly friendliness (EF) and the influence factors of the serious game, by setting the factors as the game level (GL), the demand of expectations for demand (DoE) and the prevention & usefulness of cognitive decline (PUCD). Results: the findings show that most of participants positively evaluated the EF of the serious game, regardless of their socio-demographic characteristics. Moreover, it can be found that the more the 'GL DoE and PUCD', the more the 'EF'. The EF was most strongly affected by DoE, followed by PUCD, and then GL Developing and running the serious game by actively reflecting such factors may be one of ways for enhancing the participation in the serious game for dementia prevention and facilitating the sustainable use of it.

This study examines the social and artistic aspects of the Netherlands in the 16th century, focusing on the paintings of Pieter Bruegel the Elder (1525-1569), a repre- sentative Dutch painter at that time. Also analyzed were the types and characteristics of each item of the male populace's and nobles' costumes at that point in the Renaissance. The results are as follows: most of the populace's chemises do not have frills on the neckline and sleeves; the doublet has a loose body and sleeves overall; and the sleeves and armholes are fixed with sewing rather than being detachable, making the epaulet invisible. The neckline of the doublet usually does not have a collar, but it sometimes has a hood. In the case of trousers, most males are shown wearing waist-high stockings, and a piece of cord is visible. It seems that the populace's coats were mainly Spanish-style capes. The 16th-century Dutch populace's costumes are imitative-reflecting a desire to emulate the codpieces and hairstyles of the aristocrats-while providing individuality through hats and belts. In terms of practicality, it appears that a knife and pouch were used in various living environments. This trend can be seen as a reflection of populace's perception of the costume at the time.
