With an extensive proliferation of information and communication technology, the volume and amount of digital information collected and utilized on the Internet have been increasing rapidly. Also on the rapid rise are side effects such as unintended breach of accumulated personal information and consequent invasion of personal privacy. Informational self-determination is rarely practiced, despite various states' legal efforts to redress data subjects' damage. Personal health information, in particular, is a subcategory of personal information where informational self-determination is hardly practiced enough. The observation is contrasted with the socio-economic inconvenience that may follow due to its sensitive nature containing individuals' physical and health conditions. This research, therefore, reviews factors of self-determination on personal health information while referring to the protection motivation theory (PMT), the long-time framework to understand personal information protection. Empirical analysis of 200 data surveyed reveals threat-appraisal (perceived vulnerability and perceived severity of threats) and coping-appraisal (perceived response effectiveness), in addition to individual levels of concern regarding provided personal health information, influence self-determination to protect personal health information. The research proposes theoretical findings and practical suggestions along with reference for future research topics.

We report a case of celiac artery dissection after abdominal blunt trauma. A 29-year-old man visited the emergency room for acute left periumbilical pain after abdominal blunt trauma from his child. Computed tomography showed a wedge-shaped splenic infarction with splenic artery thrombus. He was hospitalized for careful observation, and after two days, follow-up computed tomographic angiography showed a progressed celiac artery dissection that involved common hepatic artery and an increased extent of splenic infarction. He underwent conventional angiography, and a self-expandable stent was placed between the celiac axis and the common hepatic artery. After two days, follow-up computed tomographic angiography showed good hepatic arterial blood flow via the stent and no progression of splenic infarction. After ten days, he was discharged without complications.

This paper investigates an algorithm for robust fault diagnosis in robot manipulators. The TOSM (Third Order Sliding Mode observer) provides both theoretically exact observation and unknown fault identification without filtration. The EOI (Equivalent Output Injections) of the TOSM observers can be used as residuals for the problem of fault diagnosis and to identify the unknown faults. The obtained fault information can be used for fault detection, isolation as well as fault accommodation to the self-correcting failure system. The computer simulation results for a PUMA 560 robot are shown to verify the effectiveness of the proposed strategy.

The purposes of the study were to examine engineering students' concerns and problems while they were choosing a project topic in interdisciplinary collaboration and to suggest ways to support them in an early stage of collaboration phase. To answer the research questions, we conducted a case study with engineering participants in GCTI 2015, an interdisciplinary collaborative and creative group project. Multiple data sources including focus group interviews, online survey and researchers' observation notes were used to triangulate research findings. We found four main concerns of engineering students. These concerns include (1) lack of self-efficacy, (2) limited resources, (3) lack of shared, meaningful, and common goals, and (4) lack of content knowledge. Based on these concerns we proposed four supports in an early stage of the collaborative project. These supports includes (1) implementing an orientation program, (2) providing opportunities for social interactions, (3) providing expert feedback, and (4) providing consultation for team building.

The purpose of this study was to develop an educational program that enhances a single mother's social adaptation (self-esteem and sociality) based on the precedent studies. The subjects of this program were seven single motherswholive in C city in Chung Cheong Namdo. Paired-Sample t-test, individual change and group processing description data, and behavior observation record data were analyzed. Research results are as follows based on the research questions. First, a group of 8 single mothers who participated in the program showed an improvement of their social adaptation. Therefore, the effectiveness of the educational program was verified. Second, as the group session went on, the cohesion among the group members was solidified and their will to participate in the program was increased. Third, generally, individuals' understanding, acceptance, and adaptation toward themselves and others were enhanced. On the whole, the educational program for improving single mother's social adaptation was verified. We need to develop and implement more programs that enhance single mother's social adaptation in the future.

We present results from an extensive synthetic observation analysis of numerically-simulated radio galaxy (RG) jets. This analysis is based on the first three-dimensional simulations to treat cosmic ray acceleration and transport self-consistently within a magnetohydrodynamical calculation. We use standard observational techniques to calculate both minimum-energy and inverse-Compton field values for our simulated objects. The latter technique provides meaningful information about the field. Minimum-energy calculations retrieve reasonable field estimates in regions physically close to the minimum-energy partitioning, though the technique is highly susceptible to deviations from the underlying assumptions. We also study the reliability of published rotation measure analysis techniques. We find that gradient alignment statistics accurately reflect the physical situation, and can uncover otherwise hidden information about the source. Furthermore, correlations between rotation measure (RM) and position angle (PA) can be significant even when the RM is completely dominated by an external cluster medium.

This study explored the relationship between children's emotional competence, aggression and peer relationships. Participants were 164 third and 134 fourth grade children from five elementary schools in Seoul and Chenan. Emotional competence, aggression and peer relationships were assessed by means of a questionnaire, interview and observation. Results indicated that emotional understanding of self and others, sex, age, emotional expression and passive regulation strategies were significant variables in predicting children's aggression. Emotional understanding was the most predictable variable in relation to peer relationships. Emotional understanding, emotional regulation and emotional expression made independent contributions to aggression and peer relationships. Mediation analyses revealed that the significant connections between children's emotional competence and negative peer relationships were mostly mediated by aggression.

The purpose of this study is to propose scientific data and to develop complex\ulcornermultifunctional fibers by applying microcapsules containing rosewood oil on wool fabric. Polyurea was used as wall material of microcapsules. The parameters for adoptable condition are 20min of agitation time, 5000rpm of agitation speed, 4% of emulsifier concentration according to the observation with SEM and particle analyzer. The melting peak of microcapsules was shown to be 280$^{\circ}C$ The amount of released rosewood from microcapsules at 25$^{\circ}C$ was below 1 % and at 40% was below 3%. Therefore, polyurea microcapsules is capable of preserving rosewood oil for long self-life at normal temperature. Antimicrobial activity to dry cleaning and ironing cycle of wool fabric treated with microcapsules were maintained.

The slender rectangular cantilever beam has vef interesting to study dynamic behaviors of the harmonic base excitation of a cantilever beam shows many nonlinear dynamics due to unstability , energy transfer and mode coupling. Nonlinear phenomenon shows superharmonic, subharmonic, super subharmonic and chaotic motions of the cantilever beam. Experimental observation and verification of these phenomenon carry much importance for the theoretical study as well as in it self. In the experimental cantilever beam, the chaotic motions of the beam appear as a pink noise signal in FFT analysis and as a torus structure in the oscilloscope analyzed to eventually give information of chaotic motions of the cantilever beam.

The purpose of this ethnographic study was to observe and understand interactions of toddlers and teachers in context. Specific questions were "What are the motives and features of the interactions between toddlers and teacher?" Subjects were twenty 2-year-old daycare children and their teachers. Methods covered 11 weeks of interviews and participatory observation. The major findings were that the interactions between toddlers and teachers was mainly initiated by toddlers and consist of physiological and emotional needs, conflict mediation and participation in play. As toddler get to the age of self-recognition but still need adult's assistance, the co-existence of dependence and independence was evident. Children used a variety of verbal and non-verbal signals with both positive and non-positive overtons.
