Purpose: The purpose of this study was to investigate the nursing students' metacognition and learning flow. Methods: The participants in this study were 272 nursing students. Between November and December 2017, data were collected through questionnaires. Data analysis was performed using PASW (SPSS) 21.0 program, and descriptive statistics, t-test, one-way ANOVA and Pearson correlation coefficients. Results: The mean metacognition of this study was 3.53/5, and mean of learning flow was 3.34/5. The significant learning flow according to metacognition level (F=46.75, p<.001). The significant correlates of metacognition were learning flow (r=.54, p<.001). Conclusions: The finding of study showed that metacognition was very important for enhancing learning flow influenced these relationship. This study suggested that it is important to develop and implement teaching and learning strategies with improved metacognition in nursing education field.

Purpose. This study was to investigate the relationships among mobile internet addiction, sleep quality, anxiety, and interpersonal relationship in university students. Method. A descriptive study design was used. Between 10 and 31 March 2016, 213 subjects completed a questionnaire consisting of questions on mobile internet addiction, anxiety, sleep quality, and interpersonal relationship. The data were analyzed using descriptive statistics, One way-ANOVA, and Pearson's correlation coefficient SPSS/WIN 21.0 programs. Results. Among mobile internet addiction there were significant differences between gender (t=3.40, p<.001), grade (F= 2.31, p<.001), majority field (F=5.34, p=.005), and take exercise (t=3.50, p<.001). This study has shown that mobile internet addiction were associated with sleep quality (r=-.40, p<.001) and anxiety (r=.14, p=.037). In addition, a correlation has been found significant between anxiety, and sleep quality (r=.48, p<.001), and sleep quality has associated with interpersonal relationship (r=-.46, p<.001). Conclusion. In this study, we revealed the observed a meaningful significant correlation between mobile internet addiction, sleep quality and anxiety. Therefore, it is important to emphasize control of mobile internet addiction for university students. The results of this study can be used as a basis on which to develop a mobile internet addiction intervention program.

Purpose. This study was to explore the relations between self-efficacy, social support, college life adaptation and academic achievement of nursing students. Method. A descriptive study was conducted with a sample of 209 students enrolled in one college located in D City, and the data were collected during from May 14, to June 10, 2017. Data were analyzed using descriptive statistics, One way-ANOVA, and Pearson's correlation coefficient SPSS/WIN 21.0 programs. Results. Mean score for academic achievement was 3.06/4.5. Among college life adaptation there were significant differences between gender (t=9.13, p=.003), grade (F=7.07, p<.001). There were correlated between academic achievement in the nursing students, self-efficacy (r=.33, p<.001), social support (r=.31, p<.001), and college life adaptation (r=.42, p<.001). And there were correlated between self-efficacy (r=.16, p=.022), and social support (r=.22, p=.002). Conclusion. It was found that a higher degree of self-efficacy and social support, college life adaptation and academic achievement of nursing students. Therefore, to increase the academic achievement, between the social support, self-efficacy and college life adaptation are recommended.

TFT-LCD(Thin Film Transistor Liquid Crystal Display) module is representative commercial product of FPD(Flat Panel Display). Thickness of TFT-LCD module is very thin. It is adopted for major display unit for IT devices such as Cellular Phone, Camcorder, Digital camera and etc. Due to the harsh user environment of mobile IT devices, it requires complicated structure and tight assembly. And user requirements for the mechanical functionalities of TFT-LCD module become more strict. However, TFT-LCD module is normally weak to high level transient mechanical shock. Since it uses thin crystallized panel. Therefore, anti-shock performance is classified as one of the most important design specifications. Traditionally, the product reliability against mechanical shock is confirmed by empirical method in the design-prototype-drop/impact test-redesign paradigm. The method is time-consuming and expensive process. It lacks scientific insight and quantitative evaluation. In this article, a systematic design evaluation of TFT-LCD module for mobile IT devices is presented with combinations of FEA and testing to support the optimal shock proof display design procedure.

Merkel cell carcinoma (MCC) is a rare primary cutaneous neuroendocrine carcinoma which commonly presents as a skin nodule, and can develop into regional lymph node metastases, as well as spread systematically. Here, we describe the cytological features of a touch imprint of MCC that arose on the face of a 62-year-old female. This touch imprint was acquired from an incisional biopsy specimen which had been submitted for frozen section. The touch preparation produced a highly cellular imprint of loosely cohesive groups of small- to medium-sized malignant cells exhibiting uniform round to oval nuclei, delicate nuclear membranes, fine chromatin, small nucleoli, and scanty cytoplasm, with occasional paranuclear button-like inclusions. We applied cytokeratin 20 to the touch imprint for immunochemistry, allowing us to visualize the tumor cells with paranuclear dot-like positivity. Both the cytological and immunocytological features were quite distinct.

Parathyroid tumors may be difficult to distinguish from thyroid follicular lesions, especially when a tumor is nonfunctioning. We report here two cases of asymptomatic parathyroid carcinoma preoperatively misdiagnosed as thyroid follicular lesions, and one case of parathyroid adenoma showing hyperparathyroidism, and review the cytologic features favoring the diagnosis of parathyroid neoplasm. The cytologic findings that are characterized by clean background, monomorphic small cells, cohesive three-dimensional papillary clusters, small tight clusters with scattered naked nuclei, and well-defined clear cytoplasm favor a diagnosis for the parathyroid lesions. Cytologic findings such as macrofollicular structure, presence of colloid and macrophages, and presence of perivacuolar cytoplasmic granules on May-Grunwald-Giemsa stain support a diagnosis of a thyroid follicular lesion. The cytomorphology of parathyroid tumors is so variable that the distinction from a thyroid lesion cannot be based on the presence or absence of a single feature only but on the cytologic features as a whole.

The present studies was to seroepidemiological investigation with the related pneumonia due to a combination of both viral and bacterial agents. In selected herd in Jeonbuk-Iksan area of swine farms in 2006. The seroprevalence of antibody titers of PRRS, PCV-2 and mycoplasmal pneumonia were 87.2%, 69.8% and 47.4%, respectively. High seroprevalence of antibody in sow indicate that the infected sow major source of the diseases, and play an important role in circulation between production stage.

Purpose. The purpose of this study was to examine the related factors of quality of life (QOL) among middle-aged male. Method. The participants in this study were 144 middle aged male. Between October and November 2016, data were collected through questionnaires. Data analysis was performed using PASW (SPSS) 21.0 program, and one-way ANOVA, Pearson correlation coefficients, and stepwise multiple regression analysis. Results. The mean QOL of this study was 2.99/5. The significant correlates of QOL were family support (${\beta}=.21$, p=.024), health status (${\beta}=.24$, p=.003), workplace spirituality ${\beta}=.55$, p<.001), and these variables explained 55.9% of variance in QOL. Conclusion. The study suggests that family support workplace spirituality are an important factors in explaining QOL of the middle-aged male. Therefore, it is necessary to be considered family support and workplace spirituality for promoting life satisfaction of middle-aged male.

The characteristics of energy Performance for total heat exchanger have been investigated under various conditions. In cooling operation the latent and enthalpy efficiency are affected by the difference of absolute humidity ratio between indoor and outdoor air. In addition to this the characteristics of absorbing material in the element affects the energy performance. Low dry bulb temperature of indoor air or high absolute humidity ratio in outdoor air give high latent and enthalpy efficiency even with the same temperature difference of dry bulb temperate between indoor and outdoor air.
