중고령 남성 은퇴자의 은퇴만족도 변화궤적 유형과 영향 요인
송시영 한국노년학회 2024 한국노년학 Vol.44 No.2
본 연구는 고령화연구패널조사(Korean Longitudinal Study of Ageing: KLoSA)의 5차(2014년)부터 8차(2020년) 자료를 사용하여중고령 남성 은퇴자의 은퇴만족도의 변화궤적 유형을 탐색하고 각 하위집단에 속할 가능성을 예측하는 요인을 살펴보았다. 이를 위해5~8차 동안 완전 은퇴하였다고 응답한 50세 이상 남성 은퇴자 543명을 대상으로 잠재계층성장모형과 3단계 접근법 및 다항로지스틱회귀분석을 실시하였다. 잠재계층성장분석 결과, 중고령 남성 은퇴자의 은퇴만족도는 ‘고수준 유지형’, ‘증가형’, ‘저수준 유지형’으로도출되었다. 5차(2014년)에 측정한 영향 요인들을 독립변수로 투입하여 다항로지스틱 회귀분석을 실시하였다. 그 결과 주관적 경제상태, 사회활동 빈도, 주관적 건강상태, 연령이 은퇴만족도 하위집단 간 차이를 유의미하게 예측하였으며, 특히 주관적 경제상태가 높은경우에 저수준 유지형이나 증가형보다는 고수준 유지형에 속할 확률이 높은 것으로 나타났다. 본 연구를 통해 중고령 남성 은퇴자의은퇴만족도 변화궤적 유형을 세분화하여 살펴보았으며, 특히 이들의 노후준비를 위해 어떠한 차원의 대비가 필요할지에 대한 논의를진행하였다. The purpose of this study was to identify patterns of retirement satisfaction trajectory and their associated factors among middle-aged and older male retirees using data from the 5th (2014) to 8th (2020) waves of the Korean Longitudinal Study of Ageing (KLoSA). To this end, a three-step approach to the Latent Class Growth Model (LCGM) and multinomial logistic regression analysis were conducted on the sample of 543 male retirees over the age of 50 who responded that they had fully retired during the 5th to 8th waves. As a result of the analysis of the Latent Class Growth Model analysis, the retirement satisfaction of middle-aged and older male retirees was derived as 'high-level of retirement satisfaction maintaining type', 'increased retirement satisfaction type', and 'low-level of retirement satisfaction maintaining type'. The results of the multinomial logistic regression analysis showed that subjective economic status, frequency of social activities, subjective health status, and age significantly predicted the trajectories of retirement satisfaction, and in particular, it was found that those with high subjective economic status were more likely to belong to the high-level of retirement satisfaction maintaining type than the low-level of retirement satisfaction maintaining type or the increased retirement satisfaction type. This study examined the patterns of retirement satisfaction trajectory among middle-aged and older male retirees by subdividing them, and in particular discussed what level of preparation would be needed to prepare for their retirement.

Pancreatic cancer is currently the major leading cause of cancer-related deaths in the Western countries with an overall 5-year survival rate of less than 3%. The key aim of investigation is to identify the cellular population in which some of the earliest molecular events occur, presumably the ultimate target for carcinogenic insult. Advances in pathological classification and genetics have improved our descriptive understanding of this disease. However, important aspects of pancreatic cancer biology remain poorly understood. Factors associated with the increased risk of pancreatic cancer include smoking, chronic pancreatitis, diabetes, prior gastric surgery, and exposure to radiation or chemicals. A number of syndromes have been identified with the increased incidence of pancreatic cancer, including familial atypical multiple-mole melanoma syndrome, hereditary nonpolyposis colorectal cancer, and hereditary pancreatitis, etc. Recently, there have been growing evidences that stem cell biology could provide new insights into the understanding of cancer biology. Three postulates regarding the relationship between stem and tumor cells have been proposed. First, the similarities in the mechanims that regulate self-renewal of normal stem cells and cancer cells. Second, the possibility that tumor cells might arise from normal stem cells and third, the notion that tumors might contain ‘cancer stem cells' - rare cells with indefinite proliferative potential which drive the formation and growth of tumors. New insights for the cancer stem cells and their possible markers in pancreatic cancer have been suggested recently. Further observations of molecular and cellular events in the early stage of pancreatic carcinogenesis may have important implications regarding the cellular lineage responsible for pancreatic ductal metaplasia and neoplasia, and provide further support for the presence of stem cell capabilities within mature pancreatic epithelium.
