  • Reduced life-cycle and scale of electronic products make the conventional automated manufacturing system difficult to keep on competitiveness in these days. Reduced life-cycle requires an agile adaptation of manufacturing to new products and reduced scale requires enhanced precision as well as high speed. In this research, We propose a new concept called as "One-Cell Minifactory" in which various processes are combined to produce final modules or products and human interaction can be combined easily. We hope the proposed concept can guide new developments of automated manufacturing in electronics, optics and bio-engineering.

  • Patients diagnosed with cancer face mental problems such as alienation, isolation, anxiety about death and fear, recovering from psychological difficulties. In this study, a forest healing program was provided for cancer patients to recover from psychological stress, depression, social isolation and self-esteem caused by cancer and changes in salivary cortisol through psychological and emotional recovery were measured. From September 19 to November 28, 2017, a forest healing program composed of a total of 10 sessions, two hours per session was provided for 12 cancer patients in the Forest of Taegyo located in Yongin. Psychological tests were performed with Social Adaptation Self-evaluation Scale (SASS), Korean-version Perceived Stress Scale (PSS) and Beck Depression Inventory (BDI) and the collected data were analyzed with the SPSS 18.0. The salivary cortisol level was measured along with the psychological tests and were analyzed by a specialized testing agency. The results of the analysis showed that the pre- and post-assessment score of SASS was 29.17 and 25.92, respectively, and that the pre- and post-assessment score of PSS was 30.50 and 23.92, respectively. The pre- and post-assessment score of BDI was 41.00 and 34.83, respectively, which showed significant differences. In addition, the pre- and post-assessment level of saliva cortisol was 3.13 and 1.68, respectively, showing a significant decrease. In short, the forest healing program was found to be effective in reducing physiological changes caused by social isolation and stress due to the emotional and psychological difficulties that the subjects who were diagnosed with cancer and were recovering from it have. In the future, it will be necessary to develop and implement a forest healing program by conducting a forest healing requirement survey on cancer patients.

  • Purpose: The purpose of this study was to develop a Korean version of the Falls Efficacy Scale (K-FES), which is used to measure the fear of falling, that is conceptually equivalent to the original and culturally adaptable to the Korean population. Methods: A five-step translation and adaptation process was employed to create the K-FES, adhering to the established guidelines for cross-cultural rehabilitation outcome measures. The content validity was then evaluated by 22 rehabilitation professionals (15 males and 7 females) with an average clinical experience of 201 months at neurological rehabilitation centers. The content validity ratio and index were used as a basis for judgment. Results: The translation process identified inconsistencies with the terms "objects" and "telephone" in the original Falls Efficacy Scale, which were subsequently resolved in the final K-FES version. The content validity ratios for the original, second, and third versions of the K-FES ranged from -0.27-0.91, -0.27-0.91, and -0.27-0.91, respectively. Correspondingly, the content validity index values for the original, second, and third versions of the K-FES ranged from 0.77-1.00, 0.68-1.00, and 0.63-1.00, respectively. Conclusions: The K-FES was rigorously developed through translation, adaptation, and validation processes, making it a reliable tool for Korean stroke rehabilitation professionals. It is expected to be instrumental in clinical and research settings to assess postural stability and fall risk in patients with strokes and brain injuries.

  • Purpose: The purpose of the study was to examine the relationships between cognitive coping, hope, depression, and life satisfaction of hemodialysis patients based on the stress-coping model. Methods: For this cross-sectional survey, 142 participants were recruited from 10 local clinics in Seoul and Daegu during 2012-2013. The data collection instruments included the Cognitive Emotion Regulation Questionnaire, the Herth Hope Index, the Hospital Anxiety and Depression Scale, and the Satisfaction with Life Scale. The data were analyzed using descriptive statistics, t-test, ANOVA, Pearson's correlation analysis, and stepwise multiple regression. Results: The cognitive coping scores were significantly related to hope, depression, and life satisfaction. The coping strategies explained 80%, 37%, and 38% of the variances in hope, depression, and life satisfaction, respectively. The most powerful coping strategy was positive refocusing, explaining 73% in hope, 25% in depression, and 25% in life satisfaction. Conclusion: The results of the study indicate that cognitive coping plays an essential role for psychological adaptation of hemodialysis patients. Thus, interventions integrating positive refocusing would help instilling hope of hemodialysis patients in Korea.

  • Objective: To determine Korean facial profile preferences based on lip position as assessed by Hispanic-Americans of varying western adaptation levels and to determine whether the age and sex of the rater had any influence. Methods: For this study, 132 Hispanic-Americans and 68 Caucasians of varying age, sex and western adaptation levels volunteered to rate their preference of Korean male and female facial silhouettes having lips ranging from retruding to protruding. The Hispanic-Americans were also asked to complete a Bidimensional Acculturation Scale questionnaire to determine their western adaptation status: low-acculturated Hispanics (LAH; lesser western-adapted Hispanic participants) or high-acculturated Hispanics (HAH; higher western-adapted Hispanic participants). Results: The LAHs preferred significantly more retruded lip positions (p < 0.05) while HAHs showed some similarities with Caucasian participants in the results for the Korean male profile, even though HAHs preferred more retruded lip positions for the Korean female profile than Caucasians did (p < 0.05). The age and sex of raters did not influence the preference of facial profiles (p > 0.05). Conclusions: The results of this study suggest that Hispanic-Americans prefer a flatter Korean lip profile. It would be prudent for orthodontists to offer patients the option of altering lip profile through orthodontic and/or orthognathic surgery treatments.

  • Suspension culture in serum-free medium is important for the efficient large-scale culture of anchorage-dependent cells that are utilized to produce therapeutic recombinant protein(e.g., insulin, antibody, vaccine) and virus vector for therapeutic gene transfer. We developed a novel method for the suspension culture of anchorage-dependent animal cells in serum-free medium using biodegradable polymer nanospheres in this study. Poly(lactic-co-glycolic acid) (PLGA) polymer nanospheres (433nm in average diameter) were used to the culture of human embryonic kidney 293 cells in serum-free medium in stirred suspension bioreactors. The use of PLGA nanospheres promoted the aggregate formation and cell growth (3.8-fold versus 1.8-fold growth), compared to culture without nanospheres. Adaptation of the anchorage-dependent cells to suspension culture or serum-free medium is time-consuming and costly. In contrast, the culture method developed in our study does not require the adaptation process. This method may be useful for the large-scale suspension culture of various types of anchorage-dependent animal cells in serum-free medium.

  • Purpose: The depression of the elderly in recent years has been increasing every year due to the remarkable change of the psychological function, which has a great influence on the life. Depression which is a powerful predictor of suicide in elderly people, causes various psychological and social problems. In this study, we try to understand convergently about the adaptation experiences of the depressed elderly with suicidal ideation. Procedures and Methods: Seven elderly people with a GDS(Geriatric Depression Scale) score of ${\geq}17$ and a SSI(Scale for Suicidal Ideation) score of ${\geq}9$ in the self-help group were interviewed until theoretical saturation. Data were analyzed based on the Grounded theory method. Results and Contribution: Depressed elderly recognized the importance of being the center of their lives through interactions with peer groups and they started to embrace their lives. Further studies: Empirical studies on positive interactions with peer groups affecting the adjustment experience of depressed elderly should be expanded and continued.

  • Recently, climate change risk assessment has been discussed as a medium process for making climate change adaptation policies in the research field of climate change adaptation. Climate change risk assessment has been understood to have an intermediary role among impact assessment, vulnerable assessment and policy, and is used in the process of devising adaptation policies in the United Kingdom (UK). This paper quantitatively assessed the risks of climate change in Korea, applied the methods used in the UK, underwent the classification process and suggested implications of Korean adaptation policies. A survey of experts, based on Delphi's method and the classification criterion developed by Klinke and Renn(2002), was also carried out. A list of climate risks was created from the climate change impact and vulnerability assessment report of Korea, first national adaptation policy of Korea, and general climate risks of the UK. From the results, 42 risks out of total 125 risks were selected based on their importance. The assessed risks with factors, such as high impact and urgency, are related to repeated and large scale damage from storms and floods caused by abnormal or extreme weather events. Ecological changes and social infrastructure risks were engaged as required as a policy response for medium to longer term. As for making the classification, types of climate risks were suggested to manage the basic capacity in relation to social trust, triggering mechanism and responsibility. Following suggestions are put forward as the base of autonomous adaptation: increasing the capacity of civil society, mutual trust and civil participation in adaptation policy process.

  • This study conducted a vulnerability assessment on Korea's physical infrastructure to provide base data for developing strategies to strengthen Korea's ability to adapt to climate change. The assessment was conducted by surveying professionals in the field of infrastructure and climate change science. A vulnerability assessment was carried out for seven climate change events: average temperature increases, sea level rise, typhoons and storm surges, floods and heavy rain, drought, severe cold, and heat waves. The survey asked respondents questions with respect to the consequences of each climate change event, the urgency of adaptation to climate change, and the scale of investment for adaptation to each climate change event. Thereafter, management priorities for infrastructure were devised and implications for policy development were suggested. The results showed that respondents expected the possibility of "typhoons and storm surges" and "floods and heavy rain" to be the most high. Respondents indicated that infrastructure related to water, transportation, and the built environment were more vulnerable to climate change. The most vulnerable facilities included river related facilities such as dams and riverbanks in the "water" category and seaports and roads in the "transport and communication" category. The results found were consistent with the history of natural disasters in Korea.

  • The purpose of this study is to develop academic resilience scale for gifted youth. We extracted the pilot questionnaire of 101 items from open-ended questions with 178 scientifically gifted students and literature review. Item analysis and exploratory factor analysis were also carried out with data of 240 gifted youth. Finally, 11 factors from which 42 items were extracted and validated through the confirmatory factor analysis involving 444 gifted youth throughout the nation. The names of the extracted factors were sense of purpose, self-understanding, educational aspirations, academic self-regulation, task commitment, attribution for success (ability), attribution for success (effort), the interpersonal relationship (friend), the interpersonal relationship (parent), the interpersonal relationship(teacher), and optimism. The results show that all of the path coefficient and construct reliability, AVE (Average Variance Extracted), and coefficient of determination were all acceptable. The result of the study indicated that Academic Resilience Scale for Gifted Youth was positively and significantly correlated with School Adaptation Scale and Resilience Scale. However it was negatively correlated with Academic Burnout Scale, and it was statistically significant. Thus, Academic Resilience Scale for Gifted Youth demonstrated satisfactory internal validity and external validity. The results of the present study suggests theoretical and practical implications of the newly developed Academic Resilience Scale for Gifted Youth.
