This study is a methodological research study that tests the validity and reliability of the NCRC (Nurse Clinical Reasoning Competence scale), an instrument developed by Liou and his colleagues as the basic data for enhancing the clinical reasoning competence of nurses, by translating it into Korean and checking the similarity of the sentence structure and meaning (between the two versions?). This study verified its validity and reliability by examining 166 nurses working in four tertiary hospitals located in Seoul and Busan. An analysis of the content validity by experts showed that all of the items have a content validity higher than CVI 0.8. From the exploratory and confirmatory factor analysis, it was found that the instrument includes a total of 15 items consisting of one factor. In addition, the correlation with the Korean version of the Nurse Clinical Reasoning Competence scale is confirmed to test the concurrent validity, by using a measurement tool of nurses' critical thinking dispositions and clinical decision-making abilities (correlation coefficient =.55-.64(p<.001) and Cronbach's ${\alpha}=.93$). Thus, the Korean version of the NCRC may be a useful instrument for evaluating the clinical reasoning competence of Korean nurses and providing the basic data for assessing their clinical reasoning competence and developing their promotion strategies.

We examined the immune response in flounder, Paralichthys olivaceus, with immunization of formalin killed Edwardsiella tarda as an antigen. The ELISPOT-assay (enzyme-linked immunospot assay) was optimized technically and applied to count the number of total and specific antibody secreting cells (TASC and SASC) in lymphocytes of different lymphatic organs. Incubation of lymphocytes on 96 well plate for more than 2.5hrs came out enough time in ELISPOT-assay for counting the antibody secreting cells in the anterior kidney and spleen. However, too much of plate-coated antigen or rabbit anti-flounder immunoglobulin for SASC or TASC counting, respectively, was appeared to decrease the sensitivity of the assay system. Specificity of the system was also confirmed by the absence of TASC in lymphocytes treated with cycloheximide to prevent protein synthesis. The peak numbers of SASC appeared at wk 3 post immunization after that there was a sharp decrease and reached to almost zero at wk 7. In the spleen and kidney, the timing and numbers of SASC on peak response were concurrent without preferential organ distribution. The specific antibody level in the sera increased rapidly between wk 2 and 3 after immunization, i.e. like the specific cellular response found with ELISPOT-assay on that period, However, the remained high level of specific serum antibody from wk 5 after immunization until the end of experiment was clearly distinguishable from the kinetics of SASC response decreased sharply.

Recently the demand for projected capacitance touch screens is sharply growing especially for large screens for medical devices, PC monitors and TVs. Large touch screens in general need a controller of higher complexity. They usually have a larger number of driving and sensing lines, and hence it takes longer to scan one frame for touch detection leading to a low frame scan rate. In this paper, a novel touch screen control technique is presented, which scans each frame in two steps of simultaneous multi-channel driving. The first step is to drive all driving lines simultaneously and determine which sensing lines have any touch. The second step is to sequentially rescan only the touched sensing lines, and determine exact positions of the touches. This technique can substantially increase the frame scan rate. This technique has been implemented using an FPGA and an AFE board, and tested using a commercial 23-inch touch screen panel. Experimental results show that the proposed technique improves the frame scan rate by 8.4 times for the 23-inch touch screen panel over conventional methods.

Background: Lung cancer is the most common cause of cancer-related death worldwide and in Korea, and small cell lung cancer (SCLC) is the most deadly tumor type in the different lung cancer histology. Chemotherapy is the main strategy of the treatment for SCLC, and etoposide and platinum regimen has been the only standard chemotherapy for about 30 years. To test feasibility of weekly divided dose irinotecan and carboplatin for Korean patients is the aim of this study. Methods: Patients with histologically or cytologically confirmed extensive stage SCLC were included. Patients with limited stage (LD), who could not tolerate concurrent chemoradiotherapy were also included. All the patients received irinotecan $60mg/m^2$, carboplatin 2 area under the curve at day 1, 8, and 15 every 4 weeks. Study regimen was discontinued when the disease progressed or intolerable side effects occurred. No more than 6 cycles of chemotherapy were given. Results: Total 47 patients were enrolled, among them 9 patients were LD. Overall response rate was 74.5% (complete response, 14.9%; partial response, 59.6%). Side effects greater than grade 3 were neutropenia (25.5%), fatigue (12.8%), thrombocytopenia (8.5%), sepsis (4.3%), and pancytopenia (2.1%). There was no treatment related death. Conclusion: Weekly divided irinotecan and carboplatin regimen is effective, and safe as a first line therapy for both stage of SCLC. Large scaled, controlled study is feasible.
Swallowing disorders that can affect nutrient intakes and quality of life are commonly shown among the elderly as well as patients with neurogenic disorder. This study verifies the reliability and validity of the Swallowing Disturbance Questionnaire (SDQ), a subjective swallowing disability assessment tool, modified for Koreans' eating habit and cultural sentiment, against 105 stroke patients, in order to help identify early swallowing problems of the elderly. Reliability of internal consistency in the Korean version of SDQ is .601, test-retest reliability is .97, and concurrent validity is .956. Based on 8 points of cut-off score, 46.8% of sensitivity and 81.6% of specificity. Comparing the results of video fluoroscopic study (VFSS), an objective swallowing disorder test with those of Korean version of SDQ, negative predictive value (NPV) and positive predictive value (PPV) was shown as 81% and 53%. The Korean version of SDQ is expected to be a useful testing tool to discriminate swallowing disorders in stroke patients. It has great clinical significance in that swallowing difficulties shown by subjects can be sorted out to request a diagnostic assessment before clinical evaluation by a rehabilitation therapist or ruling out unnecessary exposure to additional tests by accurately identifying stroke patients without swallowing problems.

Type 2 diabetes mellitus (T2DM) is characterized by insulin resistance (IR). T2DM is correlated with obesity and most T2DM medications have been developed for enhancing insulin sensitivity. Silk protein fibroin (SPF) from spiders has been suggested as an attractive biomaterial for medical purposes. We generated transgenic rice (TR) expressing SPF and fed it to diabetic $BKS.Cg-m+/+Lepr^{db}$ mice to monitor the changes in blood glucose levels and adipose tissue proteins associated with energy metabolism and insulin signaling. In the present study, the adipocyte size in abdominal fat in TR-SPF-fed mice was remarkably smaller than that of the control. Whereas the adenosine monophosphate-activated protein kinase (AMPK)-activated protein kinase and insulin receptor substrate 1 (IRS1) protein levels were increased in abdominal adipose tissues after TR-SPF feeding, levels of six-transmembrane protein of prostate 2 (STAMP2) proteins decreased. Phosphorylation of AMPK at threonine 172 and IRS1 at serine 307 and tyrosine 632 were both increased in adipose tissues from TR-SPF-fed mice. Increased expression and phosphorylation of IRS1 at both serine 307 and tyrosine 632 in adipose tissues indicated that adipocytes obtained from abdominal fat in TR-SPF-fed mice were more susceptible to insulin signaling than that of the control. STAMP2 protein levels decreased in adipose tissues from TR-SPF-fed mice, indicating that STAMP2 proteins were reducing adipocytes that were undergoing lipolysis. Taken together, this study showed that TR-SPF was effective in reducing blood glucose levels in diabetic mice and that concurrent lipolysis in abdominal adipocytes was associated with alterations of AMPK, IRS1, and STAMP2. Increased IRS1 expression and its phosphorylation by TR-SFP were considered to be particularly important in the induction of lipolysis in adipocytes, as well as in reducing blood glucose levels in this animal model.
Objectives This study aimed to investigate therapeutic effect of Korean Medicine Steam Therapy (KMST) for leukorrhea patients. Methods From December 1st 2013 to Nov 31st 2014, 16 leukorrhea outpatients treated with KMST filled out questionnaire before and after treatments. The questionnaire was composed of 8 question items such as sleep, appetite & digestion, urination, defecation, emotion, cold hypersensitivity, menstrual pain, leukorrhea and patients were told to evaluate their symptoms as NRS score. We analyzed mean NRS score of each question item before and after KMST by using Wilcoxon's signed rank test of SPSS ver. 19. Results Mean age of participants was 40.8±13.0 years and mean value of treatment numbers per person was 3.8±1.8 times. 43.75% (n=7) of the patients had history of vaginitis caused by gardnella vaginalis, ureaplasma urealyticum or candida albicans. All patients were treated with acupuncture, moxibustion and Korean medicine. In addition, there was no side effect reported by participants. NRS score of quantity, odor of leukorrhea, perineal unpleasant sensation such as itching, dryness, burning sensation remarkably decreased (p<0.01, p<0.05, p<0.01 each). NRS score of symptoms including sleep, urination, cold hypersensitivity, menstrual pain also remarkably decreased (p<0.05). Conclusions Symptoms of leukorrhea patients including sleep, urination, cold hypersensitivity, menstrual pain, leukorrhea showed significant decrease after treated with concurrent KMST.

Objective : This study was performed to evaluate the effect of immune reaction inductive substances such as phorbol-myristate-acetate(PMA), lipopolysaccharide(LPS), dermato-phagoides pteronyssus crude extract(DPE), dinitrochloro-benzene(DNCB) and Cryptotympana pustulata(CP), the Cryptotympana pustulata extracting substance at simultaneously on the translocation of nuclear factor-kappa B(NF-${\kappa}B$) towards to the nucleus and the mRNA expression patterns of various cytokine genes in Human acute monocytic leukemia cell line(THP-1 cells), monocytes of human. Experiment : To analyze cytokine genes expression patterns, the RT-PCR method was used, measuring tumor necrosis factor(TNF)-$\alpha$ that had been secreted during cell culture in the ELISA method. The morphological change in the cell observed during THP-1 cell culture was observed using a scanning electron microscope (SEM) and the quantitative distribution in the cell NF-${\kappa}B$ was analyzed through immunocytochemistry and a confocal microscopy. Result : CP showed different influences onto the mRNA expression patterns of cytokine genes with PMA, LPS. DPE and DNCB according to the types of immune inductive substances in the THP-1 cells. The expressions of inter-leukin(IL)-10, interferon(INF)-$\gamma$, TNF-$\alpha$ and monocyte chemoattractantant protein(MCP)-1 induced by PMA were suppressed by CP while the expression of transforming growth factor(TGF)-$\beta$ was promoted. Regarding the secretion pattern of TNF-$\alpha$ according to PMA processing, its secretion amount was increased by CP concurrent processing, in case of processing CP onto PMA and LPS, We discovered that the secretion amount of TNF-$\alpha$ was increased. Upon processing PMA and LPS on the THP-1 cell strain at the same time or either additionally processing CP thereon, the movement increase towards the nucleus from the NF-${\kappa}B$ cell cytoplasm, a transcription factor was able to be observed. Conclusion : In this study, Cryptotympana pustulata extracting substance was confirmed that it had an influence on expression patterns of cytokine genes according to the actions of a variety kinds of immune reaction inductive substances processed on the monocyte THP-1 cell of humans. Therefore, additional studies as for the immune adjusting function of Cryptotympana pustulata are considered to be able to offer important materials for curing immune abnormal diseases such as atopy dermatitis afterward.

Objectives : This study developed and validated the Perceived Stigma of Delirium Scale(PSDS), which is designed to measure perceived stigma associated with delirium in patients suffering from that disorder. Methods : Based on a literature review of scales assessing stigma, a preliminary scale comprising seven items was developed. After recovering from delirium, 128 patients completed the PSDS and the Distress Thermometer (DT). Factor analysis was used to examine construct validity, and internal consistency and test-retest reliability were examined to ensure reliability. Concurrent validity was assessed using the correlation between the total scores on the PSDS and the DT. Results : Factor analysis yielded a single-factor structure from the seven candidate items. One item was excluded due to low factor loading. The internal consistency was computed and Cronbach's ${\alpha}$ was 0.85 for the total score. The overall test-retest reliability was 0.71, with items ranging from 0.58 to 0.83. The total score on the PSDS was significantly correlated with the DT score. Conclusions : The PSDS may be a reliable, valid instrument for evaluating perceived stigma in patients who have recovered from delirium. Further study of the perceived stigma by delirium patients is required to assess the implications of the PSDS for clinical practice and research.

Purpose: The obesity prevention and management program led by public health centers are important in the community. This study aims to identify the current status of obesity prevention and management programs at public health centers and perceptions regarding facilitators and barriers when implementing programs. Methods: This study used a concurrent mixed methods design. A survey was conducted to investigate the current status and infrastructure of the obesity prevention and management program at eighty-three public health centers nationwide. Nine program managers and six local residents with experience in the program were interviewed by using a semi-structured questionnaires. Results: Most of the infrastructure facilities for the program were inadequate, and insufficient budgets and lack of professional staff were identified as barriers. Facilitators included diversification of program delivery methods, operator competence, and visible outcomes and rewards. For the effectiveness of the program, it is vital to have adequate assistants, a sufficient budget, various promotional methods, and connections with various institutions in the community. On this basis, it is acknowledged that the public health center serves as a platform for preventing and managing obesity in the community. Conclusion: It is expected that infrastructure improvements in public health centers and the link with community resources are needed. In addition, there is an urgent need to set standards for obesity prevention and management programs implemented in public health centers to 'resolve regional disparities'.
