This study explored the life histories of intermarried Korean men for more than one year before and after their family dissolution. Researcher had in-depth interviews with participants who were selected by purposive sampling from the intermarried Korean men with dissoluted family conditions. Researcher employed the holistic-content approach to analyze the interviewed materials. Mandelbaum(1973)'s conceptual framework-dimensions, turnings, and adaptions-has been taken to present the analyzed contents. The dimensions of men consisted of 'request of continuous money', 'limitation of comprehensible communucation', 'premise terminated marriage: leaving home', 'inassurance of marriage maintenance'. Turnings involved 'abandoned person', 'parents' excessive protection', 'community among themselves', and 'greedy mediator'. Adaptions were observed by 'various feeling card', 'worrying about men's child', 'expecting the future', and 'stopping on foreigner as a partner'. Discussion and suggestion were presented on the basis of these findings: examination of marriage genuineness, Korean men's preparation of marriage, intervention and service for their mental health, supports for their children and strengthen of multicultural family center's function for dissolved family.

Background and Objectives: This study aimed to analyze risk factors for positional vertigo (PV) and the influence thereof on daily life and subjective quality-of-life (QoL). Subject and Methods: A cross-sectional study was conducted using data of the 2010 Korea National Health and Nutrition Examination Survey. The study population consisted of 1,274 individuals aged >40 years for whom complete dizziness-related data were available. Blood and urine tests were performed, and nutritional intake, QoL, and subjective health status were measured using a questionnaire. The associations between PV and blood/urine test data and nutritional intake were evaluated via multiple logistic regression analysis. Results: A history of PV within the previous year was reported by 98 individuals (7.7%). Advanced age and female gender were both significantly associated with such a history. Serum hemoglobin, creatinine, and triglyceride levels correlated significantly with a history of PV. Carotene, vitamin A, and vitamin B2 intakes were significantly lower in individuals with PV. Multivariate analysis revealed that only age was significantly associated with a history of PV (p=0.003). Although subjective health status score was not significantly lower in subjects with PV, subjective impairments in mobility, self-care, the performance of usual activities, and anxiety/depression were more prominent in individuals with PV. A fall history and limitations of activity were also significantly higher in individuals with PV (p<0.001 and p=0.003, respectively). Conclusions: Age was a risk factor for PV, which affected most QoL parameters, fall frequency, and the performance of normal activities.

In this study, 3 kinds of models about bike frame are simulated with static structural analysis, And fatigue life, damage and durability according to fatigue load are analyzed. A bike frame model with diamond type is compared with another model on the reinforced support with its type. In case of the reinforced support type, maximum equivalent stress or total deformation is shown with 10% or 20% more than the diamond type respectively. At both types of models, the trends of fatigue life and damage at both types are same. 'SAE bracket history' with the severest change of load becomes most unstable but 'Sample history' becomes most stable among the cases of nonuniform fatigue loads. In case of 'Sample history' with the average stress of 0 to -1MPa and the amplitude stress of 0 to 1MPa, the possibility of maximum damage becomes 3%. This stress state can be shown with 6 times more than the damage possibility of 'SAE Bracket history' or 'SAE transmission'. In case of the reinforced support type, fatigue life becomes shorter and damage probability becomes larger at the right side installed with support than diamond type. The structural result of this study can be effectively utilized with the design on bike frame by investigating prevention and durability against its damage.

This study was designed to examine the use of housing in modern Korea, and to draw the interrelation of people and housing. In-depth interviews were conducted, and the qualitative research investigated various aspects of housing history among four individuals during the different phases of social and economic transitions. 4 narratives showed the unique characteristics of life history, and the findings indicated that the housing experiences were closely related to hometown, the relation to birth family at postmarriage, economic status, and the meaning of home. The main findings were as follows: the validity to select the interviewers was proved in that the selection was based on both housing structure type and ownership, and also the research indicated that economic status and housing structure type influenced the entire housing experience of each interviewee. The use of housing varied and the implications of housing lied in social and economic contexts. The use of housing, of which the term was contrived to alternatively described housing consumption modes, and chronology were affected by such individual factors as economic status, familiar relationships, residential location, the meaning and subjectivity of housing.

This study was conducted to investigate the life history, morphology, and maturation of larval stages and adult worms of Fasciola gigantica in experimental mice. Lymnaea auricularia rubiginosa was used as the intermediate host, and Oryza sativa was used for encystment of the metacercariae, while Mus musculus was used as the definitive host for maturation study. Fresh eggs from the gall bladder of water buffaloes fully developed into embryonated ones and hatched out at days 11-12 after incubation at about $29^{\circ}C$. Free-swimming miracidia rapidly penetrated into the snail host, and gradually developed into the next larval stages; sporocyst, redia, and daughter redia with cercariae. Fully-developed cercariae were separated from the redia and shed from the snails on day 39 post-infection (PI). Free-swimming cercariae were immediately allowed to adhere to rice plants, and capsules were constructed to protect metacercariae on rice plants. Juvenile worms were detected in intestines of mice at days 3 and 6 PI, but they were found in the bile duct from day 9 PI. Juvenile and adult flukes were recovered from 16 mice experimentally infected with metacercariae, with the average recovery rate of 35.8%. Sexually mature adult flukes were recovered from day 42 PI. It could be confirmed that experimentally encysted metacercariae could infect and develop to maturity in the experimental host. The present study reports for the first time the complete life history of F. gigantica by an experimental study in Thailand. The obtained information can be used as a guide for prevention, elimination, and treatment of F. gigantica at environment and in other hosts.

This paper seeks to illuminate the intellectual context of Giljae, who had carried out a unique life during the late Koryŏ and early Chosun period and left quite a significant imprint on the Chosun intellectual history. In the midst of the tumultuous political changes in the late Koryŏ, Giljae worried the fate of the declining Koryŏ dynasty after contemplating on the directions that Yi Sŏnggye had taken after the Wihwado Retreat and made it very clear that he would rather honor the integrity of Baekyi·Sukje(伯夷叔齊). The traces that Giljae had left in this period obtained its significance not just as a loyal integrity of a subject but as a paragon of life that lived up to the principles of the Confucius truth. To decline a prestigious position in the service of a king when it was offered is not just to buy the honor of integrity. It is an endeavor to live one's life right as to how one entered the world and retreated from it in accordance with the Confucius teachings. That many kings and scholars in the Chosun period placed Giljae highly in the intellectual history of Korean Confucianism in remembering his integrity is none other than the recognition of this fact.

What kind of publicness is there in oral records? This question is the starting point of this study. To find the answer to this question, this study prepared three questions again. First, what is the public sphere and what is publicness? Second, what is the difference between oral records and other records? Third, has there been a case where oral records created publicness? This study analyzed the public sphere and publicity to achieve the purpose. Prior studies in philosophy, sociology, and politics were referenced. The results of this study are as follows. The results of this study are as follows. First, the core role of the public sphere is to provide citizens with freedom of speech. Second, oral records can record alienated information and facts and enable interaction. This study concluded that this was the publicness of oral records. This study proved this conclusion by analyzing the commentary by life history archivists who worked in the 2021 Digital Life History Archiving project.

Stress and deformation on forklift happened at loading, unloading or moving freight are studied by structural and fatigue analysis in this study. As model 1 as closing type between forks has lower stress and stain than model 2 at opening type, model 1 has more durability than model 2. Among the cases of nonuniform fatigue loads, 'SAE bracket history' with the severest change of load becomes most unstable but 'Sample history' becomes most stable. In case of 'SAE bracket history' with the severest change of load at model 1 and 2, maximum life is shown with Cycle. Minimum damage with 854 at model 2 becomes much higher than model 1. As the gap between forks becomes open, the damage probability becomes higher. The structural result of this study can be effectively utilized with the safe and stable design of forklift by investigating prevention and durability against its damage.
