Purpose: The purpose of this study was to investigate depression, loneliness, and social support status of the elderly using smartphone. Method: In this descriptive design study, 100 elderly people using smartphone were recruited through convenient sampling between August and September, 2014. Questionnaires used for this study were CES-D(The Center for Epidemiological Studies-Depression Scale), UCLA Loneliness Scale, and social support scale developed by Park. Data were statistically analyzed using SPSS 22.0 program with descriptive statistics, independent t-test, one way ANOVA with Scheffe's test, and χ2-test. Result: Smartphone usage duration had significant influence on depression(=0.000) and loneliness(=0.001) of the elderly using smartphone. In detail, depression scores of participants using smartphone less than 6 months were higher than participants of more than 2 years(p=0.004). And both depression and loneliness scores of participants using smartphone 6 to 1 year were higher than participants of more than 2 years(=0.001). But smartphone usage time had no significant influence on depression and loneliness of the elderly using smartphone. Conclusion: The result of this study suggest that smartphone usage duration is significantly related to both depression and loneliness of the elderly. Therefore, smartphone education program for the elderly would be a helpful intervention for depression and loneliness of the elderly. And further studies are required with more sample size and more systematic data collecting methods to confirm these results.

Mixed-mode fatigue crack growth analysis using peridynamic approach

Jung, J.,Seok, J. IPC Science and Technology Press ; Elsevier Scienc 2017 International journal of fatigue Vol.103 No.-

<P>A new method is developed in this study to extend the peridynamic fatigue model for mode-I crack case proposed by Silling (2014) to a mixed-mode (mode-I and mode-II) crack case. To determine the model parameters, application of the modified Paris law incorporating the effective stress intensity factor model of Tanaka (Tanaka, 1974), is also proposed. Furthermore, a method is developed to decompose the peridynamic J-integral separately into mode-I and mode-II. The decomposed J-integral values are then used to compute and analyze the change in the stress intensity factor of each mode during crack propagation. The proposed model is validated by comparison with existing experimental results and shows that a mixed-mode fatigue crack growth rate can accurately be predicted under various load conditions. Additionally, the associated computation time is significantly reduced by formulating a matrix-based peridynamic code that uses a graphics processing unit. (C) 2017 Elsevier Ltd.

Aberrant ventral striatal responses during incentive processing in unmedicated patients with obsessive–compulsive disorder.</P><P><B>Objective: </B> Obsessive–compulsive disorder (OCD) is characterized by the dysfunction of control and reward mechanisms. However, only few neuroimaging studies of OCD have examined the reward processing. We examined the neural responses during incentive processing in OCD.</P><P><B>Method: </B> Twenty unmedicated patients with OCD and 20 age‐, sex‐, and IQ‐matched healthy controls underwent functional magnetic resonance imaging while performing a modified monetary incentive delay task.</P><P><B>Results: </B> Compared with controls, patients with OCD showed increased ventral striatal activation in the no‐loss minus loss outcome contrast and a significant positive correlation between the ventral striatal activation and compulsion symptom severity. In addition, patients with OCD showed increased activations in the frontostriatal regions in the gain minus no‐gain outcomes contrast. During loss anticipation, patients with OCD showed less activations in the lateral prefrontal and inferior parietal cortices. However, during gain anticipation, patients with OCD and healthy controls did not differ in the ventral striatal activation.</P><P><B>Conclusion: </B> These findings provide neural evidence for altered incentive processing in unmedicated patients with OCD, suggesting an elevated sensitivity to negatively affect stimuli as well as dysfunction of the ventral striatum.</P>

In a trial involving 240pigs, the proximate composition, physico-chemical properites, color, amino acid composition and fatty acid composition of loin muscle were investigated in feeding various finished pig fees. The treatments included feeding control) the low-nutrient density diet(2,960㎈/㎏ ME, 12.25% CP, 0.41% lysine and 0.70% Ca), T1) the medium-nutrient density diet(3,220㎈/㎏ ME, 15.50% CP, 0.87% lysine and 0.90% Ca) and T2) the hight-nutrient density diet(3,350㎈/㎏ ME, 17.50% CP, 1.05% lysine and 0.90% Ca). The crude ash contents of T1 were significantly(p<0.05) higher than those of control and T2. The ?_(u) of T2 were significantly higher than those of control and T1, but cooking loss were significantly(p<0.05) lower than those of control. In compositions amino acid, aspartic acid, threonine, iso-leucine and histidine of T2 were higher than those of control, but proline and glycine were significantly(p<0.05) lower then those of control. The oleic acid(18:1) contents of control were significantly higher than those of T1 and T2, but the contents of linoleic acid(C18:2) and arachidonic(C20:4) acid were significantly(p<0.05) lower. Inconclusion, the results of the experiments suggest that the high-nutrient density diet for pigs tended to improve the postmortem ?_(u) and cooking loss.

In a trial involving 120 pigs, the effects of transport time on blood profile and meat quality in pigs were investigated. One group of 60 animals was subjected to 20min and the others to 2 h transport time, and held in lairage for 1 h 30min. There was not significantly different in the carcass weight, backfat thickness and carcass grade between groups. Cortisol and lactic dehydrogenase(LDH) concentrations were significantly(P<0.05) higher in the group transported for 2 h compared with the group transported for 20min. There was not significantly different(P>0.05) in meat quality(?_(1), ?_(u), drip loss, cooking loss, hardness, CIE L^(*), a^(*), b^9*) and NPPC) and skin damage of port carcass between groups. These results imply that the stress could be affected by transport time in transit without meat quality.

Purpose: This study aims to analyze the difference in the perception that nursing students and medical students have regarding the image of nurses. Method: The sampling group for this study was made up of 111 nursing students and 117 medicine students, conducted from the 19th August 2013 to 3rd September 2013. The tool used for this study is the “Nurse Image Scale”. The data is analyzed using the SPSS 21.0 program, technical stats, t-test and ANOVA with Scheffe test. Result: There was a notable difference in the results(t=6.94, p<001), with the average image perception score of nurses at 3.84±0.34 amongst nursing students being higher than the 3.50±0.38 amongst Medicine students. The average score of the 4 areas tested, “Qualification of a Nurse”, “Role of a Nurse”, “Social Participation of a Nurse” and “Interpersonal Skills of a Nurse” were all marked higher by the nursing students than the medicine students. The average score became notably higher as the period of practice became shorter with nursing students (F=4.21, p=.043). Furthermore, the average score for the “Qualification of a Nurse” was notably higher as the period of practice became shorter (F=3.98, p=.049). Medical students gave an average score for the “Qualification of a Nurse”(F=3.72, p=.027) and the “Interpersonal Skills of a Nurse”(F=4.11, p=.019) which was relative to the development of a nurse’s image, while the average score for the “Role of a Nurse” was notably higher with a longer period of practice(F=6.65, p=.011). Conclusion: The results of this study suggest that the image perception of a nurse can vary depending on the experience in period of practice. Therefore, together with this study conducted with nursing students and medicine students, there is a need for further studies conducted on image perception of nurses with various experience in period of practice.

Purposes :The purposes of this study was to investigate the self-managing status according to the life styles and the diabetic knowledge of early adulthood. The subjects in this study were 240people, the early adult aged twenties to thirties living in the metropolitan area. Data were collected by using self-administered questionnaires that measure about the knowledge of diabetes; the dietetic behavior; the knowledge of diet; the exercise behavior; the knowledge of exercise. Descriptive statistics, t-test, ANOVA, and correlation were used for data analysis. Result :1. At the knowledge of diabetes degree based on the general character, the subjects who had experiences of diabetic education have higher degree of the diabetic knowledge. 2. At the knowledge of diabetes degree according to the life style, the subjects who have regular diet are appeared highly. Also the subjects who don't take much food of animal origin have higher degree. 3. At the knowledge of diet based on the life style, the subjects who don't keep three times meals a day are appeared highly. Also the subjects who have regular diet have higher degree. 4. At the knowledge of exercise according to the life style, the subjects who take extra nutritions 3-4 times a week are appeared highly. Although the subjects tend to know about dietary, exercise and health management, it showed that they actually don't perform what they know in their everyday of life. The reason for this could be the lack of perceived seriousness about diabetes mellitus. Thus as nursing professionals, we should provide them proper health education and support. Moreover, advanced research on the empowerment is warranted.

We tried to inquire the people's views on nursing or nurses, correct the image of nurse and take it as a basis to be applied on nursing education examining the image of nursing on Television drama playing a important role of mass media. 523 nurses of the characters in drama is applied to the analysis object of this study by selecting 3 American medical dramas, Grey's Anatomy, House M.D, E.R from 2005 to 2007. Contents analysis method was used in Data Analysis, which was used in Lim Mi-lim ?Research on contents analysis on image of nursing on television drama?, 7 Items was used after Coders previously modify and compensate it based on research documents of Kalish & Kalisch(1986), Yoon Young(1983), Lee Hye-Ok(1982), Lee Young-Bok, etc in analysis items. Before making the coding, we did pre-test. 6 Coders made of 3teams, 2 Coders are in each team, made the Codings the article on each person by Item seeing the recorded Film. An each team makes coding about 50episodes, total 147episodes for 2weeks. We used double coding and when the results are different between two coders, we decided just one result through mutual agreement. The average of reliability degree was 97.4% which measured the reliability degree by the method of Holsti. The statistic method of Frequency, Percentage was used using EXCEL Program in data processing. The result of research is as follows. 1. The general feature of nurses on the drama is that they are women(92.7%) which is 20 or 30-aged(70.5%). 2. Relative importance of 65.2% nurses in drama is depicted as surrounding characters and most of them was expressed as the character plating surrounding role. 3. The affair attitude of nurses shown on drama is revealed as active(24.5%), autonomous(32%), kind(16.8%), mechanical(23.2%) and adept(28.4%). However, unknown category is the highest in all affairs. 4. The professional activity of nurses was classified with professional/simple affair, The professional activity of nurses was 80% and simple activity of nurses was 22.9%. The professional activity of nurses was classified with personal/assistant affair. The personal activity of nurses was 61.9% and assistant activity of nurses was 15.1%. 5. The place nurses of the drama appears are hospital(97.7%). 6. The appearance feature of nurses is shown on common physique (55.0%), common stature(79.3%), common appearance(76.1%), common dignity(97.5%) and decent (51.1%). 7. The feature of character of nurses depicted on Television drama is neutral in all 11 affairs. We want the following epigraph based on above conclusion. 1. The continuos research intended for mass people is required about how their image of nurse is changed after watching medical drama. 2. The research to construct monitoring mass media system and make plans for developing is required for nurse image being in a triangular position as a professional job.
