Based on an analysis of the Japanese animation director Kamiyama Kenji's Ghost in the Shell: Stand Alone Complex series, this paper discusses two important subjects in modern technoscience-cyborg and old age. In fact, age has been an important social and political category in the modern world, along with gender, race, and class. However, age has not been a significant research topic for STS scholars. Even though many of these investigators have extensively explored the complex relationship between gender and technoscience, especially after the publication of Donna Haraway's "Cyborg Manifesto" (1991), few of them have been interested in how age is reconfigured by modern science and technology. If women, as Haraway has claimed, can have a different political and cultural outlook by becoming cyborgs, then, can we expect a similar socio-cultural transformation with regard to the interaction between cyborg and old age? Do the elderly experience lesser age discrimination through the growth of biomedicine and technoscience? Indeed, it is believed that seniors are increasingly becoming cyborgs with advancing age, since their declining bodily functions are consistently replaced and assisted by various biomedical technologies. Does this enable them to overcome ageism and age discrimination as well as their alleged physiological and mental limitations? As an answer to this question, Mike Featherstone has asserted that becoming a cyborg in old age could make the wrinkled skin a mere mask and create diverse new possibilities that were hitherto unavailable to an aging person. Based on my reading of Ghost in the Shell, however, I analyze a more complex set of problems when the senile cyborg is created through the encounter between the elderly and technoscience. I argue that while the senile cyborg could challenge traditional family ideology and nationalism it would leave ageism intact and define a new individualistic life form through a body controlled within the globalized internet and capitalist economy.

실험동물에서 짧은 기간 감염시킨 후 얻은 간흡충(Clonorchis sinensis)에서는 거의 볼 수 없지만, 간, 담도 수술 또는 부검을 실시할 때 사람에서 얻은 간흡충중에는 검은 색소를 갖는 것을 관찰할 때가 있다. 이 색소는 살아 있는 간흡충에서도 명백하며, 색소가 없는 간흡충은 색이 분홍빛이고 투명한데 비하여 색소가 있는 것은 검은색을 띠고 불투명하다. 사람에서 얻은 간홉충 모두가 검은 색소를 갖고 있는 것은 아니며, 이제까지의 경험으로는 30세 이상 어른에서 얻은 간흡충중 그 길이가 약 1cm이상인 것에서 나타난다. 이 색소의 성분에 대하여 과거에는 빌리루빈, 또는 숙주 혈구세포에서 유래한 철을 포함하는 색소일 것이라고 생각하고 있었다. 저자등은 이 색소가 간흡충의 노쇠현상과 관련된 것으로 생각하고, 그렇다면 lipofuscin일 것이라고 생각하였다. 위의 가정을 확인하기 위하여 육안적으로 분명히 검은 색소가 있은 충체의 조직절편을 만들고, H & E, prussian blue, bilirubin, Fontina-Masson, PAS, amylase-PAS, Ziehi-Neelsen 및 AFIP method for lipofuscin등 8가지 조직화학적 염색을 실시하였다. 색소는 H & E, prussian blue, bilirubin, montana-Masson염색으로 착색되지 않았으며, PAS, amylase-PAS, Ziehi-Neelen, 및 AFIP method for lipofuscin에 염색되어 이것이 조직화학적으로 리포푸신 색소임을 확인하였다. 색소를 다시 전자현미경으로 관찰한 바 색소과립안에는 모양이 등글거나 타원형이고 크기가 $0.05~0.240{\mu}m$인 세포막구조가 산재하였음을 발견할 수 있어 간흡충의 검은 색소는 리포푸신 색소임을 다시 확인할 수 있었다.

The hot electron induced effective channel length modulation (${\Delta}L_{H}$) and HEIP characteristics in PMOSFET's after bidirectional stress are presented. Trapped electron charges in gate oxide and lateral field are calculated from the gate current model, and ${\Delta}L_{H}$(${\Delta}L_{HD},\;{\Delta}L_{HS}$) is calculated using trapped electron charges and lateral field. It has been found that ${\Delta}I_{d}$and ${\Delta}L_{H}$ are more affected by the stress order (Forward-Reverse of Reverse or Reverse-Forward) than the stress direction, and they vary logarithmically with the stress time. In contrast, ${\Delta}V_{t}$ and ${\Delta}V_{pt}$ are more affected by the stress direction thatn the stress order. The correlation between ${\Delta}V_{pt}$ and the stress time can be explanined as the following polynomial functin: ${\Delta}V_{pt}$=AT$^{n}$. It has also been shown that PMOSFET degradation is related with the gate current and the effects of ${\Delta}V_{pt}$ is the most significant.

Tocopherol, Se and garlic powder were dieted to hatched chick breeding. The Se content of certain organs is influenced by garlic powder supply. The high Se content for the testis was a function of the vitamin E uptake. Effect of low dose of Se on the growth and survival of rat were examined under the diet of $2\;{\mu}g/ml$ of Se in drinking water either in the form of $Na_2SeO_3$ or $Na_2SeO_4$. The females were dead in early ages while the males were not influenced by dieting the selenite did not make males dying rapidly at early ages and males were less growth depressed. The previously known fact that garlic act as a tonics may be attributable to its high contents of Se and sulfur-containing amino acids which are closely related to vitamin E. Further details on the dietary mechanisms of the Se, vitamin E, and garlic powder are described in this paper.

The purpose of this study is to understand the origin of the super-aged rural community and the meaning of the elderly's life in such a unique society by looking into the elderly's life from the past to the present to the future. For the study in-depth interviews have been done with 16 old people living in Geumdong village, Imshil-gun of Jeonbuk Province, one of the most aged communities of Korea. By analyzing their statements, 4 themes have been found from 11 meanings of statements on the past life, which is characterized by their fight against bonds of extreme poverty and misfortune. On the present life, which is characterized by their bare existence in senility and their endless sacrifice for the children as they are never free from the physical pains accompanying the ageing and the concern about their children, 5 themes have been found from 14 meanings of statements. About the future life, which is characterized by their calm acceptance of the fate of their later life and their village which they think will disappear after they die, 3 themes have been found from 7 meanings of statements.

Korean laws use several different terms to refer to seniors. This study looks into how older persons are defined in the laws with an aim to critically review the implications of the naming of older persons. For this goal, the laws that have been enforced since 1948 and those effective as of October 20 in 2011 were subject to analysis. The findings of this research are as the following. Korean laws have used a number of terms, including the terms meaning the old and infirm (nosoeja), old individuals (noin, goryeongja, noyeonja), and the old and weak (noyakja). However, such naming does not seem to be based on age. An analysis of noin and goryeongja, two most common terms used in Korea's legal provisions, shows the difference between social perceptions of seniors and the semantic formation of the terms. For example, noin is used in the context in which seniors are viewed rather negatively as subjects of social protection while goryeongja, a relatively neutral term, is preferred when the law sees the elderly as productive resources. It can be said that the perceived social values on senior citizens are reflected in the laws.

Objectives: This study examined the nutritional status according to frailty status in the elderly at home. Methods: The participants were a total of 76 elderly at home living in Seo-gu, Gwangju, Korea. The nutritional status and frailty status were analyzed using the Nutrition Quotient for Elderly (NQ-E) and the Korean version of the Fatigue, Resistance, Ambulation, Illnesses and Loss of weight Scale (K-FRAIL), respectively. Results: The distribution of frailty status was robust (17.1%), pre-frailty (38.2%) and frailty (44.7%), and its distribution was significantly different in genders, age groups and the number of medications. The mean NQ-E score was 47.0 for total subjects, indicating a low grade. The scores of balance, diversity and dietary behavior factors were within the low grade, while the score of the moderation factor was within the medium-high grade. According to the frailty status, pre-frailty and frailty showed significantly higher scores for sugar-added beverages intake in the moderation constructs than robust. Robust showed significantly higher scores for the exercise hours and perception level for one's health than pre-frailty and frailty. Conclusions: These results suggest that nutrition status is associated with frailty status. Regular nutrition education and visiting nutrition service should be established to improve the balance and diversity of food intake and improve the dietary behavior of the elderly at home.

This study conducted with 268 female elderly who visited welfare center and senior citizen center in Changwon city to identify the dietary status according to social frailty stage using nutrition quotient for elderly (NQ-E). As a result of the survey, 75.0% of the elderly had no nutrition education. The elderly in social frailty stage was 43.7%, pre-frail was 35.1%, and robust was 21.2%. The scores of NQ-E (61.65), balance (47.78), moderation (86.18), and dietary behavior (55.23) were within the medium-high grade, while diversity (48.37) was within the medium-low grade. Among the balance factor item, there was a significant difference only in the frequency of fruit intake according to social frailty stage (p<0.05). Among the diversity factor item, there were significant differences in vegetable intake (p<0.05) and the rate of eating alone (p<0.001) according to social frailty stage. Among the dietary behavior factor item, there were significant differences in whether to strive for a healthy diet (p<0.05), exercise time and depression (p<0.001), and subjective recognition rate of health (p<0.01) according to social frailty stage. Based on these results, education focusing on various food intake is needed, and continuous support from the government and local governments is needed to connect the social support network of the elderly and support programs to prevent them from going to social frailty stage.
