This study is about the re-validation evaluation of the family Relationship Scale (FRS), developed to measure the family relationship in the social work practice. This study aims at re-validating the FRS, developed and validated in by Yang in 2001 for more general utilization. The sample was married mates and females residing in Seoul. For Face Validity, the content analysis was performed, and the FRS was re-validated in the dimensions of Love & Caring, Acceptance, and Recognition, positive affection, empathy, and autonomy and flexibility for each area. Internal reliability was .93, and internal consistency among three dimensions was 93%. For Empirical Validity, the Construct validity, the Criterion validity, and the Discriminant validity were performed. Construct Validity was validated through factor analyses. Commonalities for the factor analysis was 54%, and the factor loading for each factor was over .45. The confirmative factor analysis also confirmed the fitness of the scale. For Predictive Validity of Criterion Validity, regression analysis showed that the family stress scores became lower as the scores of the family relationship became higher; the discriminant analysis revealed that the family stress turned low ill tile group of high scores of family relationship. The Correlation analysis for Concurrent Validity was performed and the results showed the positive and significant relationship with a couple communication level (r=54) and a parent-child communication level (r=64). Life satisfaction and mental health level also revealed significantly positive correlation to prove Convergent Validity. Physical health level revealed a weak relationship with family relationship providing the evidence of Discriminant Validity. Discriminance was also proved by the analysis of variance with demographics. Thus, Cross Validation was confirmed the validation of the FRS through the various analyses with the married population. This study result improved the validity generalization of the Scale and verify the generalized usage of this sociometric scale in the field of social work practice.

Purpose: The purpose of this study was to examine the correlation between a flexible parental visiting environment and parental stress in neonatal intensive care units (NICUs). Methods: The study participants included 60 parents of premature infants in NICUs. Structured questionnaires and interviews, as well as observations by researchers using a caregiving behavior checklist, were used to measure the flexibility of the parental visiting environment and parents' stress levels. Quantitative and qualitative data were collected concurrently and were initially analyzed as separate data sets. Data collection extended from March 11, 2018 to June 30. 2018 and the data were analyzed using descriptive statistics, the independent t-test, one-way analysis of variance, and Pearson correlation coefficients. Results: There was a negative correlation (r=-.30, p=.021) between parental stress and the total number of visits in 7 days. We also found that the average duration of each visit and the number of caregiving behaviors performed by parents were positively correlated (r=.73, p<.001). Conclusion: When designing a flexible visiting environment for parents, parents should be encouraged to visit their babies. By doing so, stress can be reduced both for babies and for parents. Therefore, it is suggested that the related polices and regulations in South Korea should be changed to provide more a flexible visiting environment to promote better parent-child attachment and family adjustment.

The proliferation of the Internet of Things (IoT) technologies and applications, especially the rapid rise in the use of mobile devices, from individuals to organizations, has led to the fundamental role of secure wireless networks in all aspects of services that presented with many opportunities and challenges. To ensure the CIA (confidentiality, integrity and accessibility) security model of the networks security and high efficiency of performance results in various resource-constrained applications and environments of the IoT platform, DDO-(data-driven operation) based constructions have been introduced as a primitive design that meet the demand of high speed encryption systems. Among of them, the TMN-family ciphers which were proposed by Tuan P.M., Do Thi B., etc., in 2016, are entirely suitable approaches for various communication applications of wireless mobile networks (WMNs) and advanced wireless sensor networks (WSNs) with high flexibility, applicability and mobility shown in two different algorithm selections, TMN64 and TMN128. The two ciphers provide strong security against known cryptanalysis, such as linear attacks and differential attacks. In this study, we demonstrate new probability results on the security of the two TMN construction versions - TMN64 and TMN128, by proposing efficient related-key recovery attacks. The high probability characteristics (DCs) are constructed under the related-key differential properties on a full number of function rounds of TMN64 and TMN128, as 10-rounds and 12-rounds, respectively. Hence, the amplified boomerang attacks can be applied to break these two ciphers with appropriate complexity of data and time consumptions. The work is expected to be extended and improved with the latest BCT technique for better cryptanalytic results in further research.

The main purpose of this study was to examine the effects of drama activities using children's literature on the improvement of young children's creativity. To answer this research question, 2 groups, an experimental group composed of 18 five-year-old children who attend "J public Kindergarten," and a control group composed of 18 five-year-old children who attend "H public Kindergarten," were organized. Both kindergartens were located in Hwaseong, Gyeonggi-do. The experimental group participated in drama activities twice a week; 16 times for 8 weeks. In this study, the change in children's creativity was measured by conducting a pre-test and a post-test developed by Chun(2000). The results after 8 weeks of experimentation indicate that the drama activities using children's literature had a positive effect on promoting children's creativity. Comparing the scores of the pre-test and the post-test, it was obvious that the experimental group's creativity had been improved. The experimental group's creativity including the sub-elements of the test such as fluency, flexibility, uniqueness, and imagination, was improved more than that of the controlled group.

A uridine diphosphate-glucose:sterol glycosyltransferase-encoding gene was isolated and cloned from the established fosmid library of Micromonospora rhodorangea ATCC 27932 that usually produces the aminoglycoside antibiotic geneticin. The gene consists of 1,185 base pairs and encodes a 41.4 kDa protein, which was heterologously expressed in Escherichia coli BL21(DE3). In silico analyses of the deduced gene product suggested that it is a member of the family 1 glycosyltransferases. The recombinant protein MrSGT was able to catalyze the transfer of a glucosyl moiety onto the C-3 hydroxy function in sterols (β-sitosterol, campesterol, and cholesterol), resulting in the corresponding steryl glucosides (β-sitosterol-3-O-β-ᴅ-glucoside, campesterol-3-O-β-ᴅ-glucoside, and cholesterol-3-O-β-ᴅ-glucoside). This enzyme prefers phytosterols to cholesterol, and also shows substrate flexibility to some extent, in that it could recognize a number of acceptor substrates.

The purpose of this study is to perform an analysis on the design methods of the "UR Housing Stock Renewal Design Competition" for Hanahata No.27 Housing by the UR Renaissance Agency in Japan. The analysis is done by looking at the aspects of lifestyle, demographics, environment, and community changes. The results are as follows: 1) Since demographic changes are caused by low fertility, aging populations need the support of locally-based social welfare facilities of which the architectural aspect can be examined. 2) Changes in lifestyle, such as diversity of family composition, flexibility of work, and improvement of leisurely activities require residents to have public spaces and facilities 3) Since environmental changes caused by deteriorated housing need the conversion of awareness about housing estates as a social asset. 4) To revitalize the community, houses, public facilities, and communal outdoor spaces must be connected. The results of this study are expected to serve as clues to the future direction of sustainable conversion in Korea.

License mechanisms are the key elements in almost all DRM(digital rights management) systems. The license mechanisms are designed for the clear identification and enforcement of contents, principals, and usage rules in DRM systems. But current license mechanisms are lacking in the flexibility for the secure and efficient sharing of the contents among the members of a group such as a family or a part of an enterprise. This paper suggests a new license mechanism for efficient and secure sharing of contents in DRM systems among the members of a group. We named it member/group license mechanism. The mechanism extends the current license mechanisms by introducing new concepts such as group licenses, member licenses, and derivation relationships between licenses.

It is essential to maximize the advantages of long-life housing in consideration of the occupants' demands in order to promote the construction of long-life housing. The diverse plan types with flexibility should be developed based on those demands. Therefore, this study aims to review the level of awareness of long-life housing, and identify the customer needs by conducting the survey for the preference to pre-defined plan types. The results of survey are as follows: 1) Despite the enforcement of the Long-life Housing Certification System in 2014, the recognition among the customers about the long-life housing is still on the low level as shown in that 79.9% of respondents were not aware of the long-life housing; 2) For three alternative plan types, 78.5% on the integration type in front, 63.1% on the moving kitchen type, 47.0% on the Divided Housing type had intention to change; 3) 68.9% of the total are willingly ready to purchase the long-life housing under the condition of no difference in price between normal apartment and long-life housing. The less the number of family members is, the bigger this ratio of positive purchase intention is. Reflecting these results into the designs is expected to contribute to the enhancement of customer satisfaction as well as the diffusion of long-life housing.

Purpose: The purpose of this research was to describe the decision making of nurses in a VIP ward. Method: The methodology of collecting and analyzing the data was based on the grounded theory of Strauss and Corbin (1998). The data were collected through an in-depth interview, which were audio-taped and transcribed. The data were collected from 10 nurses from July to November 2007. Results: The core category on VIP ward nurses' decision making was named as "adjusting with flexibility and deepened insight". The causal condition was established by 'the patients who wanted to be treated specially'. The contextual conditions included 'caring patients from various departments', 'differences depending on the nurses' clinical experience', and 'client-centered atmosphere in the VIP ward'. The intervening conditions included 'problem solving styles of nurses', 'attitudes of patients and family members', 'nurse-doctor relationships', and 'accessibility to information'. It was confirmed that nurses changed their action-interaction strategies depending on the intervening conditions, thus resulted in the nurses' role conflict and the need to expand their consciousness. Conclusion: The result of this study indicates that nurse's decision making depends on their experiences and the nature of social context in which nursing occurs.
