This study explored how retirement satisfaction or dissatisfaction influences on retirees' life satisfaction, comparing to workers and the gender differences were examined. The study sample was 2,609 persons (1,886 workers, 723 retirees) aged 45 or older who participated in the 1-2 waves of the Korean Longitudinal Study of Ageing (KLoSA), and the retirees were classified into continuously dissatisfied retirees and satisfied retirees during wave 1 and 2. Using SPSS 21.0, the multiple regression models were examined, and in order to clarify the gender difference, the multi-group analysis and the wald-test were conducted to test the difference of the regression coefficients according to gender using Mplus 7.3. According to the results, the life satisfaction of dissatisfied retirees was lower than that of the employed, but when satisfied with retirement, the life satisfaction was higher than that of the employed. In addition, the dissatisfied retirees in both gender were less satisfied with life than the employed, and this effect was greater in female group. However, the life satisfaction of female satisfied with retirement was higher than that of the employed, whereas the evidence of the male influence was not found to be significant. Based on the results of this study, discussion about heterogeneity of retirees and gender differences in life span were presented.

Compared with public archives, personal archives are likely to disappear if creators don't preserve and manage them. So personal archives must be managed by oneself. But it's difficult to manage their archives systematically for people who don't have the expertise in archival science. Besides, there are not enough available informations. So this thesis suggests how to manage personal archives by two steps. First step is figuring out one's own archives through analyzing one's life by top-down approach and organizing them into collection. Second step is conducting archival appraisal by three steps and establishing classification schemes, describing them. Especially, this study adduce description elements using ISAD(G) for personal archives. this study also recommends using blogs on portal to manage one's archives easily. But they don't have the audit train and exporting function. So this thesis emphasizes the necessity of 'customized archive blogs'. At conclusion, this study highlights the necessity of developing education programs and manuals for people who are trying to manage one's own archives.

To prepare for the explosive increase in maintenance costs of bridges according to the aging of infrastructure, future maintenance costs of bridges should be predicted. For this purpose, the management status of bridges was investigated and modeled as the upper limit of the performance level and the target management level according to the life cycle. This paper proposes methodologies and procedures for estimating the bridge maintenance costs using two models and existing cost and performance prediction models that consist of unit repair cost model according to the safety score, performance degradation model of bridges, unit reconstruction cost, and average reconstruction time. To verify the applicability, future maintenance costs can be forecasted for specific management agency considering the number of bridges, degree of aging, and current management status. As a result, it is possible to obtain the maintenance cost and safety level of an individual bridge level for each year. In addition, by summing them up to the agency level, the average safety score, ratio of the safety level, inspection costs, repair costs, and reconstruction costs can be obtained. In a further study, the changes in maintenance costs can be analyzed according to the changes in the target management levels using the developed method. The optimal management level can be suggested by reviewing the results.

Part-time jobs in Sweden are highly feminized yet are in fair conditions in terms of job security, earnings, and collective representation. Three points are considered to be important to understand why part-time work in Sweden carries such positive characteristics. First, the part-time work in Sweden is widely spread not as a result of employers' need for labor flexibilization but as means to enhance the work-life balance, a value pursued within a broader social policy package to change the breadwinner model. Second, discrimination against part-time workers is restrained in Sweden because the boundary between part-time and full-time is not conspicuous. Most of part-time jobs are occupied by regular workers who exert the right to part-time work, hence may go back to the full-time status any time. Third, the regulation on overtime work of part-time workers as well as full-time workers is strong. It is largely agreed among researchers that part-time work contributed greatly to an increase of female employment rate in Sweden. Since the 1970s, the increased availability of part-time jobs induced married women who used to be economically inactive to the labor market and maintained them to be economically active throughout the child rearing period. From the gender perspective, one may still raise issues regarding part-time work in Sweden such as persistent feminization and strong occupational sex segregation. However, the observed trend shows that the part-time work in Sweden has functioned more as a stepping stone to the full-time work for women than as a women's trap.

This study was conducted for a review of Park Se-chae's Theory of Rituals and eclectic features. He was in agreement with Song Si-yeol's allegation and Seoin's theory of rituals(西人禮論) in the 1659 controversy over propriety(己亥禮訟) and the 1674 controversy over propriety(甲寅禮訟). After that, he was cautious and criticized for Song's claims in 1683 discussion of Hyojong's sacrifices and Taejo's posthumous name. This tendency can be seen in his paper of rituals. He wrote "服制私議"(Private opinion of mourning clothes) etc. in his early life and wrote "關西昏喪契約束"(Covenant on wedding ceremonies and mourning ceremonies in the Gwanse province), "喪祭値疫痘說"(Mourning ceremonies and sacrifice when there is an epidemic) etc. in his later life. By comparing the books, we can identify changes in Park Se-chae's eclectic features. Early in life, he reviewed Gorye(古禮, Rituals of the old such as Liji) and the timely institutions(時制) on the "朱子家禮"(A book written by Zhuzi about family rituals). However, later in life, he reviewed Gorye and the Zhuzi Jiali on the timely institutions. The following is a summary of the above. His theory of rituals can be said that the eclectic features have changed from 'on Zhuzi Jiali' to 'on the timely institution'.

The Korean art history academia has lately been carrying out active research on the Korean art market and art collectors. This area of research is significant in that it attempts to overcome the limitations of previous research trends focused on tracing back and analyzing preeminent masters, their schools and their influence, and approach new subject matters such as art and society, circulation and consumption of art works, which were unapproachable with previous research methods. This paper examines the life, artwork and art collection activities of Songeun(松隱) Yi Byeong-jik(李秉直: 1896-1973), an outstanding painter, calligrapher and art collector during the Japanese colonial period. The primary purpose of this paper is to advance the research project the author has recently initiated on modern Korean art collectors by reconstructing parts of this major art collector's individual lifestyle and to generally identify the art collection activities and the art works that he kept. Yi Byeong-jik, one of the preeminent art collectors during the colonial period, disposed his voluminous collection through two auctions in 1937 and 1941, and then held another auction two weeks before the onset of the Korean War on June 25, 1950 to sell off the remaining works. It seems that the reason why Yi had auctioned off his collections was for the purpose of investing in education. The tale that Yi safely kept 'Sam-guk-yu-sa(三國遺事),' which is considered a national treasure, even through the time of turbulence is evidence of his exemplary behavior as a model art collector. He may be one of the best examples of what an art collector should be in terms of giving back to the society and preserving things of beauty and value. However, one factor that limited and defined Yi's life was that he was a eunuch. This aspect of his life could be pointed out as the biggest factor that stopped him from becoming a mainstream participant in the art world despite his influence as a great painter, calligrapher, significant art collector, and discerning connoisseur.

Although tropical cyclones with wind speeds weaker than 17 ms^-1 (weak tropical cyclones: WTCs) can cause significant damage, particularly over the Seoul metropolitan area, only a few studies have focused on WTC activity over South Korea. In this study, we found that WTC activity is likely associated with the Pacific Decadal Oscillation (PDO). During the negative phases of the PDO, landfall frequency of WTCs increased significantly compared to the positive phases at 95% confidence level. When related to the negative phases of the PDO, a positive relative vorticity anomaly is found in the northern sector of the western North Pacific while a negative relative vorticity anomaly and enhanced vertical wind shear prevail in the southern sector of the WNP. These factors are favorable for the northward shift of the genesis location of tropical cyclones on average, thereby reducing the total lifetime of WTCs. Moreover, a high-pressure anomaly over the Japanese islands would shift a tropical cyclone track westward in addition to the landfall location. Consequently, the effects of the topographical friction and the Yellow Sea Bottom Cold Water on a tropical cyclone may increase. These conditions could result in a weaker lifetime maximum intensity and landfall intensity, ultimately resulting in WTCs becoming more frequent over South Korea during the negative phases of the PDO.

In this study, the toxic effects of PFOA and PFOS potassium salt on Mesocentrotus nudus using 10 min-fertilization rate and 48 h-normal embryogenesis were confirmed through the calculation of toxicity values such as Non-observed effective concentration, Low-observed effective concentration, and 50% of effective concentration. The case of 10 min-fertilization rate and 48 h-normal embryogenesis showed the concentration-dependent reduction pattern when exposed to PFOA and PFOS potassium salt, in tested concentration, respectively. The EC50 values of 10 min-fertilization rates for PFOA and PFOS potassium salt were 1346.43 mg/l and 536.18 mg/l, respectively, and the EC50 values of 48 h-normal embryogenesis were 42.67 mg/l and 17.81 mg/l, respectively. Both toxicity test methods showed high toxicity sensitivity to PFOS potassium salt. Recent studies have shown that the concentration of PFOA and PFOS in the marine environment has continuously decreased, and it is not enough to show acute toxicity to sea urchin. However, PFOA and PFOS have a very long half-life and can accumulate throughout the life of marine life, so it is still observed at a high concentration in shellfish. Therefore, a study on chronic toxicity through the whole-life cycle of marine organisms in coastal environments should be needed.
