The National Health Insurance Corporation (NHIC) was performed population health checkup survey program with especially two target ages, 40 years and 66 years old that were called as "life transition period" for national collective prophylaxis of cardiovascular diseases in Korea. We were investigated and compared between two age groups with the serum levels of cholesterol and triglyceride from data of the survey in Daegu province, Korea at April, 2007. Data of one hundred persons per each age (40 years and 66 years old) were collected and investigated for risk factors for chronic degenerative diseases including serum lipid concentration, health habits of drinking, smoking, exercise etc. In spite of the definite difference of life transition of the each age, the transition from adolescence to adulthood at 40 years old, and from adulthood to senescence at 66 years old, there were no significant difference of total cholesterol and triglyceride between two age groups.

The purpose of this study is to understand how late middle-aged women in our society view and adapt to “aging”. This is a crucial step forward linking two stages, the growing young age and the declining old age, which eventually improves the qualify of life in old a9e. This qualitative study used Personal narratives extracted from tape-recorded interviews of 20 late middle-aged women in their fifties and analyzed key experiences of late middle-aged women in their transition to old age. Participants were observed to perceive not only many limitations but also alternative potentialities. First, the major challenges due to the closing young era were ‘physical declines’, including health problems and wrinkles, and ‘leaving children’. Second, the potentialities to start a new era also could be found. Many participants found themselves to be generous enough to assist others in need. In addition, they looked to adapt to new challenges. It was likely that the many adversities that they had faced made them resilient. These results show that late middle-aged women were actively negotiating with themselves and their surroundings in order to overcome their losses, maintain their potentialities, and, in the process, acknowledge their impending old age for better preparation.

본 연구는 한국노동패널 2차, 7차, 12차 자료를 활용하여 노년기로의 이행에 따른 소득불평등의 변화와 소득이동성을 분석하였다. 분석 결과는 다음과 같이 요약된다. 첫째, 비노년기에서 노년기로 이행할 때 소득불평등 수준이 증가하는 것으로 나타났다. 둘째, 비노년기에서 노년기로 이행하는 시기에 소득순위의 변동이 크게 나타나고, 노년기로의 이행이 이루어진 이후 노년후기로 갈수록 소득순위가 고착화되는 경향이 나타났다. 셋째, 노년기로 이행할 때 소득불평등 수준을 증가시키고 소득순위의 변동을 야기하는 가장 큰 요인은 근로소득의 감소이다. 이러한 분석 결과는 노년기로 이행할 때 근로소득의 감소가 소득불안정성을 야기한다는 사실을 의미한다.

This paper investigates how firm age, size and ownership are related with job creation and destruction, and how these patterns differ across transition and non-transition economies. The analysis finds that age is inversely related with gross job creation and net job creation in the two samples. This finding is consistent with the theory of the learning effect. The relationship between age and job destruction is indifferent in non-transition economies. On the contrary, old firms in transition economies destroy more jobs than young ones. The paper further establishes an inverse relationship between size and gross job creation in the two groups. However, there is divergence between the two samples; small firms in non-transition economies also exhibit a higher gross job destruction rate. Consequently large firms have a higher net job creation rate. In transition economies, small and large firms exhibit similar rates of job destruction. But small firms retain a higher net job creation rate. A more intriguing finding is that state owned firms do not underperform domestic private ones. This means these countries may be using soft budget constraint which allows state owned firms to overstaff. Finally, crowding out of SMEs by foreign owned firms is not evident in transition economies.

본 연구는 노년기 거주형태의 변화 궤적에 따른 삶의 만족도와의 관계를 종단데이터의 분석을 통해 살펴보고자 하였다. 이를 위해 본 연구는 국민노후보장패널 1-4차년도(2005-2011) 자료를 활용, 1-4차년도 조사당시 거주형태를 측정, 두 시점간 거주형태 변화 유형을 16개 유형으로 구분, 일반화추정방정식모형(Generalized Estimation Equation; GEE)을 적용해 삶의 만족도 차이를 분석하였다. 연구 결과 노년기 거주형태 변화는 삶의 만족도와 관련이 있었다. 전반적으로 마지막 조사시점에서 부부상태를 유지했던 집단의 삶의 만족도 수준이 높았다. 또한 노년기 자녀와의 동거여부는 삶의 만족도에 직접적으로 중요한 요인이 아닌 것으로 나타났다. 본 조사결과 자녀와의 동거는 부부가 함께 동거였을 경우에만 삶의 만족도 수준이 높았을 뿐 홀로 자녀와 동거하는 가구의 경우 독거를 지속한 가구보다도 오히려 삶의 만족도 수준이 낮은 것으로 나타났다. 노년기 거주형태 변화의 궤적과 대표적 심리적 복지 개념인 삶의 만족도의 관계를 분석한 본 연구는 노년기 거주형태 변화 차이가 삶의 만족도에 미치는 영향력을 종단자료 분석을 통해 실증적으로 제시했다는 점에서 의의를 찾을 수 있다.

Purpose: The purpose of this study was to compare the clinical and radiographic features of temporomandibular joint (TMJ) osteoarthritis (OA) between adolescents and middle-old aged patients. Methods: The subjects were chosen among the patients who presented to the Department of Oral Medicine of Pusan National University Hospital and were diagnosed with TMJ OA by clinical exam, X-ray and cone-beam computed tomography (CBCT) from 2010 to 2011. We investigated 93 adolescent patients (12-19 years) and 53 middle-old aged (>45 years) patients who observed the erosive bony changes in TMJ. CBCT scans were retaken at intervals at an average of 8 months. Results: The adolescent patients showed unilateral degenerative changes more often, and the middle-old aged patients showed degenerative changes more frequently on both sides. The transition of bone changes to the improved group occurred most commonly in both the adolescent and middle-old aged patients. The adolescent patients were more likely to improve than middle-old aged patients. In the adolescent patients, loss of erosion and subjective symptoms occurred in shorter periods than in the middle-old aged patients. In the adolescent patients, the transition of erosion was distributed into proliferative, normal, and shortening in order. In the middle-old aged patients, the transition of erosion was distributed into shortening, proliferative, and normal in order. Conclusions: The clinical and radiographic features of TMJ OA are a significantly different between the adolescent and middle-old aged patients. Moreover, the difference by age of the adaptive and regenerative capacity of TMJ affects the prognosis of TMJ OA and adolescent patients have a better prognosis after treatment.

Vessel elements in lateral root, tap root, transition region, stem and mid vein of 1-year old, 3-year old and 5-year old ginseng (Panax ginseng C.A. Meyer) are studied with light microscope to clarify the distribution and differentiation of several kinds of vessel elements. Vessel elements are classified into five types such as ring vessel, spiral vessel, scalariform vessel, reticulate vessel and pitted vessel according to the secondary thickenings of cell wall. All of the five types are not observed in each organ, but diverse kinds of vessels are present in stem and mid vein compared with the underground organs such as tap root and lateral root. The length of vessel elements is longest (680$\mu$m) in stem and shortest (143$\mu$m) in tap root. The diameter of vessel elements is 19.0$\mu$m in tap root and the angle of perforation plate comes under 22$^{\circ}$-60$^{\circ}$. The degree of differentiation of vessel elements according to the length, diameter and angle of perforation plate of vessel elements is highest in tap root regardless of the age of ginseng. Three types of perforation plate such as scalariform, intermediate type of simple and scalariform, and simple perforation plate are observed. The vascular tracheids are characteristically observed in mid vein of 1-year old ginseng, and in transition region of 3 and 5-year old ginseng.

우리나라 노동시장은 자영업의 비중이 크고 연령집단에 따라 자영업 비중의 차이가 크지만, 경기변동이 자영업 이행에 미치는 영향의 연령집단별 차이에 대한 연구는 미흡하다. 이에 본 연구는 한국노동패널 5~11차 자료를 활용하여 구축가설과 유인가설을 중심으로 분석하였다. 분석결과, 실업률이 높을수록 자영업 이행률이 높아져 구축가설을 지지한다. 기업가 정신의 발현보다는 노동시장여건의 악화로 자영업으로 밀려난 것으로 볼 수 있다. 연령집단별로 보면, 청년층에 비해 30대와 40대의 자영업 이행률이 높다. 경제활동이 왕성한 30~40대가 주변부 노동시장에 진입할 확률이 높아서, 자영업이 특정 연령계층의 문제가 아님을 알 수 있다. 또한 40대의 자영업 이행은 직업기회가 제한될 때 급증하여, 경기불황에 자영업으로 밀려가는 것으로 나타났다. 40대의 고용이 경기변동에 취약한 것을 말해준다.

Purpose: The purpose of this study was to provide basic data for use in development of strategy for healthy aging preparation and successful transfer to old age by identifying factors influencing quality of life of the baby boom generation. Methods: The data were collected from a total of 205 members of the baby boom generation(aged 48 to 56), and analysis was performed using descriptive statistics, t-test, ANOVA, Pearson's correlation coefficient, and stepwise multiple regression using the SPSS(Version19.0) program. Results: Burden for taking care of children, aging anxiety, preparations for old age, and quality of life according to the general characteristics and health-related characteristics commonly showed a significant difference in education level and presence of stress. The greater the more burden for taking care of children and the deeper the aging anxiety, the lower the quality of life, and the better prepared for aging, the higher the quality of life. Factors affecting quality of life in the baby boom generation included preparations for old age, burden for taking care of children, monthly household income, and quality of sleep. Explanatory power was 32%. Conclusion: For successful transition to old age and for improvement of quality of life in the baby boom generation, a comprehensive approach in micro and macro dimensions will be sought.

Objective: This study aimed to examine parenting education participation of Korean mothers in the transition to parenthood and its related variables. Method: A study sample was composed of 870 mothers whose first child was younger than one-year old from the Panel Study on Korean Children in 2008(mean age=30.1, SD = 3.69). The descriptive statistics of parenting education participation were presented. In addition, negative binomial and logistic regression models were used in Stata13 in order to examine the variables related to parenting education participation of mothers in the transition to parenthood. Results: Approximately 82% of the mothers reported that they had participated in at least one parenting education program. Further, mother's educational level, monthly household income, mother's working experience, and community type generally predicted parenting education participation of mothers. However, the effects of these variables varied by the subjects and the providing institutions. Conclusion: This study provides the overall picture of parenting education participation of Korean mothers in the transition to parenthood and its related variables. The findings can be utilized to plan more effective parenting education programs for new parents.
