Assurance of the objectivity and reproducibility is a major key point in wrinkle measurement used for evaluating the degree of skin aging. The measurement of relief is quickly converted to a non-contact method, of which tools or instruments do not come in contact with skin directly, to minimize the artificial effects which influence the shape or depth of the relief. Here, we showed how wrinkle measurement techniques have been changed briefly and compared PRIMOS and replica method in the point of view of measurement principle and features, the former is non-contact fringe projection tool and the latter is contact type of the method.

In this study, a retrieval system taking advantage of term relationship in a specific domain and also of evidential reasoning as tools for measuring relevance is implemented. For this experiment, techincal memoranda documented in Electronics and Telecommunications Research Institute (ETRI) served as a sample document file. Sample knowledge base was prepared by extracting terms and term relations pertaining to telecommunications from INSPEC thesaurus. Relations between terms were represented by numerical values according to types of term relations. Relationship between a query and a document was measured according to Dempster-Shafer theory of evidence. As a result of this experiment, a more comprehensive search was made by expanding search terms utilizing term relations. Measure of relevance represented by reflecting term relations, and search results were listed in a descending order of relevance.

Purpose: This study was conducted to identify the disease adaptation and related factors for the pediatric patients with diabetes mellitus. Methods: Participants in this study were 75 diabetic children or adolescent whose age were 10 to 18 years old visited the out-patient clinic in one general hospital located in Seoul. Data were collected using self-report questionnaires. Research tools measuring resilience, family support, psychological adaptation, Hemoglobin A1c (HbA1c) protein were used. Results: Resilience showed significant differences according to the age, gender, academic achievement, and hospitalization experience of the children. Family support was significantly different according to the age, religion, academic achievement, fathers' education level, and hospitalization experience of the children. Psychological adaptation to diabetes showed significant differences according to academic achievement. HbA1c was shown to be significant difference according to fathers' education level and hospitalization experience of the children. Positive correlations were identified among resilience, family support, and psychosocial adaptation, while negative correlations were found between HbA1c and all others including resilience, family support, and psychosocial adaptation. Conclusion: This study suggests that the educational programs as nursing intervention needs to be developed to enhance the resilience and family support for the pediatric diabetic patients.

In the present study, AA 5083-O plates are joined by friction stir welding technique. A universal milling machine was used to perform the welding process of the work-pieces which were fixed on the proper position by a vice. The joints were friction stir welded by two tools with different pin profiles; cylindrical threaded pin and tapered smooth one at different rotational speed values; 400 rpm and 630 rpm, and different welding speed values; 100 mm/min and 160 mm/min. During FSW of each joint, the temperature was measured by infra-red thermal image camera. The welded joints were inspected by visually as well as by the macro- and microstructure evolutions. Furthermore, the joints were tested for measuring the hardness and the tensile strength to study the effect of changing the FSW parameters on the mechanical properties. The results show that increasing the rotational speed results in increasing the peak temperature, while increasing the welding speed results in decreasing the peak temperature for the same tool pin profile. Defect free welds were obtained at lower rotational speed by the threaded tool profile. Moreover, the threaded tool pin profile gives superior mechanical properties at lower rotational speed.

Purpose: Compliance in kidney transplant recipients is critical for a positive prognosis. Especially compliance with medications after kidney transplantation is a major health care issue with implications for graft rejection and graft loss. But the definition of compliance in transplantation varies among centers. The purpose of this study was to clarify the concept of compliance in kidney transplant recipients. Methods: A literature search was conducted using RISS, MEDLINE, CINAHL. The concept analysis was guided by the methodology posited by Walker and Avant. Results: In this study, we found the attributes of the concept: 'compliance with immunosuppressive medication', 'compliance with follow-up', 'compliance with early detection of graft rejection and complication', and 'compliance with prevention of complication'. The antecedents of 'compliance in kidney transplant recipients' included 'having a kidney transplant surgery' and 'normal function of transplanted kidney'. The consequences of 'compliance in kidney transplant recipients' included 'affecting the function of the transplanted kidney' and 'affecting the health of kidney transplant recipients. Conclusion: This study may contribute to the development of tools for measuring compliance in kidney transplant recipients, as well as benefit nursing interventions research to increase compliance in kidney transplant recipients.

Purpose: The purpose of this study is to explore the trends of research related to ethical topics in Korean nursing students. Methods: A total of 131 articles that were published from 2000 to 2020 were analyzed and summarized according to publishing type, research design, subject, data analysis method, main research topic, research variables and instrument. Results: Most studies were journal articles (93.9%) and their most frequent research design was survey (75.7%). The research subjects covered all grades (35.1%) or they were divided between clinical nursing practicum (29.8%) or not (21.4%). The main research topics were biomedical ethics, ethical values, moral judgment and ethics education. Recently, ethical decision making and practical ability in nursing practice were reported. The instruments for measuring variables were limited and the same tools were used several times. Conclusion: Based on the findings of this study, it is suggested that the selection of various research topics and the application of research methods related to ethics for nursing students will continue in response to rapidly changing social phenomena in the future. In particular, it is necessary that research related to ethical and practical ability as well as ethical attitudes and perceptions of nursing students be actively carried out.

In this study digital human models of ship construction tasks using modeling & simulation were constructed and human models' activities through human activity analysis were evaluated. Human Factors experts analyzed the actual workers' tasks using the same technique used in human activity analysis at the same time. The main objective of this study is to check a possibility of applying digital human modeling technique to ship construction tasks that are mostly non-standardized(not uniformed) whereas most applications of digital human modeling technique have been applied to standardized tasks. We evaluated postures of both real workers and digital humans by RULA. It turned out that the final scores of RULA evaluation on real workers are the same as the RULA scores for digital humans. However, there were differences of RULA detail scores between real workers and digital humans in the several processes related with the wrist twist and deviations. Those differences are considered to be resulted from the error in the on-site measuring worker's body dimension which could be reduced by accurate tools to correct data for body dimension and digital real drawings for facilities. The results showed possibility of application of digital human modeling and ergonomic analysis on informal work operations as well as formal operations in the shipbuilding industry.

Research in the machine tool industry has focused on ICT-based smart machines rather than hardware technologies related to machine tools. Real-time tool-status monitoring is representative of this type of technology and has become important for measuring sensors during cutting processes. In this paper, we studied several research areas and used a round bar to conduct fundamental research into the axial displacement of the main spindle of a tool when it was subjected to a machining load. We were able to use the gap sensor to detect the axial displacement indirectly by using grooves with various shapes on the round bar and sensing the gaps between the grooves. We then determined the optimal groove shape for monitoring the tool state.

Muscle vibration measurement has long been an unique scientific study, in general, and the direct reaction of animals to feel pain (algesia), either from vascular or muscle contraction, is a complex perceptual experience. Thus this paper proposes a way to measure animal algesia quantitatively, by measuring the changes in muscle vibration due to a pinprick on the surface of the skin of a Spodoptera litura larva. Using the laser optical triangulation measurement principle, along with a CMOS image sensor, linear laser, software analysis, and other tools, we quantify the subtle object point displacement, with a precision of up to $10{\mu}m$, for our chosen Spodoptera litura larva animal model, in which it is not easy to identify the tiny changes in muscle contraction dynamics with the naked eye. We inject different concentrations of formalin reagent (empty needle, 12% formalin, and 37% formalin) to obtain a variety of different muscle vibration frequencies as the experimental results. Because of the high concentrations of reagent applied, we see a high frequency shift of muscle vibration, which can be presented as pain indices, so that the algesia can be quantified.

Purpose: This study was designed to identify burnout and factors influencing burnout in contingent nurses. Methods: A cross-sectional design was conducted with a sample of 228 contingent nurses randomly selected from 25 general hospitals in Korea. The tools used for this study were scales measuring burnout (8 items), job stress (8 items), job satisfaction (9 items), self efficacy (9 items), organizational commitment (9 items), empowerment (9 items), autonomy (7 items) and social support (8 items). The data were analyzed using SPSS 15.0 employing Pearson correlation coefficients and multiple regression analysis. Results: The mean score for burnout in contingent nurses was 3.05 points. Factors influencing burnout in contingent nurses were identified as job stress (${\beta}$=.40), satisfaction level with current ward (${\beta}$=-.25), organizational commitment (${\beta}$=-.21), job satisfaction (${\beta}$=-.19) and empowerment (${\beta}$=-.16). These factors explained 65.0% of burnout reported by contingent nurses. Conclusion: The results indicate which factors are major factors influencing burnout in contingent nurses in general hospitals. Therefore, these factors may serve as predictors of burnout in contingent nurses.
