This study investigated various attributes that contributed to successful employment in order to develop employment support programs, especially for female engineering students. We surveyed engineering students who graduated between 2006 and 2011. The 401 employed graduates participated in an online survey. The surveys inquired about their attachment towards their major, participation in various academic and non-academic activities, and their participation's contribution to their successful employment. In regards to their majors, women, in general, had lower levels of satisfaction, confidence, attachment, and motivation to succeed in their fields when compared to their male counterparts. These results show that engineering colleges still need to work on empowering female engineering students to gain confidence in their engineering major and attachment. The graduate school experience was highly rated by both men and women, whereas double majors exhibited somewhat lower scores. Among academic activities, part-time work experience and major-related internships were rated as the most helpful, and among extracurricular activities, study-abroad for language training and participation in student council or clubs received high scores. There was little difference between men and women in study-abroad participation, and women participated more actively in student councils. However, women had much less major-related work experience, reaffirming that colleges need to expand internship and field experience programs for female students.

Background: Various characteristics such as size distribution, chemical component and radio-activity have been analyzed for radioactive aerosols released from Fukushima Daiichi Nuclear Power Plant. Measured results for radioactive aerosols suggest that the potential transport medium for radioactive cesium was non-sea-salt sulfate. This result indicates that cesium isotopes would preferentially attach with sulfate compounds. In the present work the attachment behavior of fission products to aqueous solution aerosols of sodium salts has been studied using a generation system of solution aerosols and spontaneous fission source of $^{248}Cm$. Materials and Methods: Attachment ratios of fission products to the solution aerosols were compared among the aerosols generated by different solutions of sodium salt. Results and Discussion: A significant difference according as a solute of solution aerosols was found in the attachment behavior. Conclusion: The present results suggest the existence of chemical effects in the attachment behavior of fission products to solution aerosols.

Background: This study aimed to identify the types of adult attachment and determine the relationship between adult attachment and job factors in dental hygienists. Ultimately, it was necessary to identify the need for a secure attachment to improve the quality of clinical dental hygienist's services. Methods: Data of 454 clinical dental hygienists working in dental hospitals or clinics were collected. The research tools consisted of items related to the general and work characteristics of dental hygienists (9 items), adult attachment styles (36 items), organizational commitments (12 items), occupational stress (15 items), and interpersonal relations (18 items). Cronbach's ${\alpha}$ of each tool was ${\geq}0.7$. Results: Most of the participants had fearful attachment styles, followed by dismissing-avoidance, security, and preoccupation. Security was the highest level of organizational commitment according to the adult attachment style, although the differences of the levels were insignificant. For occupational stress, preoccupation was the highest, followed by fearful, security, and dismissing-avoidance, and the differences were significant (p<0.001). For interpersonal relations, security was the highest, followed by preoccupation, dismissing-avoidance, and fearful in order, and the differences were significant (p<0.001). Conclusion: Job stress and interpersonal relation ability according to the adult attachment style of clinical dental hygienists had significant results. Thus, the development of attachment improvement programs by personal style, development of differentiated clinical education and its application, and improvements in the adult attachment styles of clinical dental hygienists would be required rather than simply presenting the needs to collectively improvement the working environment.

Purpose: The purpose of this study was to identify the influence of self-differentiation, psychological discomfort, and marital dyadic adjustment on maternal-fetal attachment in primigravida. Methods: In total, 108 primigravida participated in this descriptive correlational study. The participants answered self-report questionnaires. Data were collected from January to May, 2020, and were analyzed using descriptive statistics, the t-test, analysis of variance, Pearson correlation coefficients, and hierarchical multiple regression with SPSS for Windows ver. 23.0. Results: The mean age of the primigravida was 31.66 years. The mean score for the degree of maternal-fetal attachment was 76.81 out of 96 points. Participants' scores for maternal-fetal attachment differed significantly based on age (t=2.08 p=.039) and marital status (t=2.05, p=.043). Maternal-fetal attachment was significantly negatively correlated with psychological discomfort (r=-.39, p<.001), and significantly positively correlated with self-differentiation (r=.36, p<.001) and marital dyadic adjustment (r=.36, p<.001). Self-differentiation explained 24.1% of variance in participants' maternal-fetal attachment, and its effect was statistically significant (F=7.79, p<.001). Conclusion: In primigravida, more self-differentiation was associated with stronger maternal-fetal attachment. To strengthen maternal-fetal attachment in primigravidae, educational program that increases the level of self-differentiation and minimizes psychological discomfort may be helpful for first time pregnant women. Additionally, it is recommended to provide nursing interventions to encourage couples to work together throughout the gestational period.

This study proposes a new framework for designing disassembly methods. In recent years, environmental problems have become global issues. Recycling of used products or resources is recognized as a matter of significance since it may help reduce the risk of exhausting natural resources. Considering possible exhaustion of limited natural resources in the near future, reuse of products would gain more environmental significance. As yet, it relies hugely on manual disassembly, which labor cost places burden on the total recycling cost. The purpose of this study is to propose a methodology designing for manual disassembly works, and a creation method of a jig. By focusing on parts' connection and attachment relationship, parts are categorized in 5 categories (parent part, joint key part, attaching key part, child part, and independent part) according to the features that parts possess, and 3 kinds of connection relationships (parent part-joint key part connection, parent part-independent part connection and child part-child part connection) are clarified. Connection relationship and attachment relationship charts have also been created, and utilizing them, disassembly orders are settled, and a disassembly jig is devised. The proposed methodology is also applied to a real product and its work time is improved 42% form 31 to 13 seconds.
