  • Objectives : Early detection and proper management of distress are known to be important for efficient care in cancer patients. The aim of this study was to investigate the prevalence of distress and to evaluate its influence on quality of life in subjects with breast cancer. Methods : A total of 95 patients were recruited from a breast cancer patient community of a general hospital in Seoul. The Hospital Anxiety and Depression Scale(HADS), the Insomnia Severity Index(ISI), the Impact of Event Scale-Revised(IES-R) and the Functional Assessment of Cancer Therapy-Breast(FACT-B) were measured. Results : The prevalence of anxiety, depression, insomnia and posttraumatic stress disorder symptom among breast cancer patients was 26.3%, 26.3%, 13.7%, 24.3%, respectively. Nearly half(47.4%) of total subjects were under one or more significant distress, and they showed significantly lower mean FACT-B total score than patients without distress(82.91 vs. 107.20, p<0.001). Distress was negatively correlated with the quality of life to a significant level even in patients who were in normal range of distress scale scores. Conclusion : These results support the importance of regular screening and proper management of distress for breast cancer patients.

  • In this study, we wanted to understand the impact of different decaffeination processes on aroma compounds of coffee. Therefore, we analyzed differences in physical characteristics and volatile aroma compounds profiles of regular coffee (RC), Swiss water process decaffeinated coffee (SWDC), and supercritical CO2 decaffeinated coffee (SCDC) after roasting the coffee beans. The electronic nose analysis identified RC and SCDC as different groups which indicates that these groups volatile aroma compound compositions were different. The principal component analysis of volatile compound patterns identified using an electronic nose indicated that there was a large difference in volatile compounds between RC, which was not decaffeinated, and both decaffeinated SWDC and SCDC. The major aroma compounds of RC, SWDC and SCDC were propan-2-one and hexan-2-one which are ketone, and hexanal and (E)-2-pentenal which are aldehyde and 3-methyl-1-butanol which is an alcohol. After roasting, the composition of major volatile compounds appearing in the beans was similar, but the relative odor intensity was different. We identified 28 volatile aroma compounds from RC, SWDC, and SCDC using headspace-solid phase microextraction-gas chromatography/mass spectrometry (HS-SPME-GC/MS), and analyzed 10 major compounds that were present in high abundance, including furfural, 2-furanmethanol, 2,5-dimethylpyrazine, and 2-ethyl-3-methylpyrazine.

  • The study investigates how the structured debriefing method affects the learning flow, critical thinking disposition, and clinical performance of nursing students, using the Lasater Clinical Judgment Rubric (LCJR). Nursing students in the 4th grade of P University were divided into three groups, each trying out a different structured debriefing method: the experimental group - structured video debriefing using the LCJR question, the comparative group - structured oral debriefing, and the control group - structured group discussion debriefing. There was no significant difference between the three groups in learning flow (p=.640), critical thinking disposition (p=.420) and clinical performance ability (p=.360). Planning and intervention among the areas of clinical performance were significantly improved in the experimental group compared to the other two groups (p=.005). Structured debriefing when used with LCJR improves the learning flow and critical thinking disposition of students, while structured video debriefing improves clinical performance.

  • Objectives : Though gastric cancer is one of the most common cancer in Korea, there have been few studies to explore psychological distress in gastric cancer. The purpose of this study was to investigate the prevalence and associated risk factors of psychological distress among patients with gastric cancer. Methods : With consecutive sampling, a total of 274 patients with gastric cancer who admitted to a cancer center in a general hospital were recruited and assessed on psychological distress using the Hospital Anxiety and Depression Scale(HADS). Sociodemographic and cancer-related clinical variables were also evaluated. Results : One hundred fifty-three(55.8%) patients with gastric cancer showed psychological distress. Logistic regression models revealed that having alcohol drinking experience[odds ratio(OR)=2.10, p=0,034] and low performance status(OR=2.40 p=0.002) were significantly associated with psychological distress in patients with gastric cancer. Conclusions : These findings indicate that approximately half of patients with gastric cancer suffered from psychological distress and having alcohol drinking experience and low performance status would be associated risk factors, suggesting the need for distress screening and psychosocial supportive care in patients with gastric cancer.

  • British TV Channel 4 is one of the famous TV Channel in the world. Its station ID has also played a leading role in the developments of Motion Graphics including station IDs. This station ID's main visual design concept is its name and an iconic logo '4' at the same time. The first channel 4 station ID was designed by using modular typography to construct the iconic '4'. Modular typography is a technique of creating letters with similar elements. Channel 4's station ID was constructed from coloured polygons. The polygons split and converge at the same point in 3D space. Modularity in Channel 4's station ID is evidenced by the similar units of polygons. After the first station ID, Channel 4 was re-branded. Eventhough the station IDs which followed did not use coloured and geometrical polygons, modularity is seen in most of the station IDs especially between 2004 - 2011. In these station IDs, the iconic '4' is formed from similar natural and environmental objects like rocks, buildings, lights etc. In this analysis paper, there is a visual narrative on the history of Channel 4, the concept of modular typography in the original station ID and the application of modular typography in other Channel 4's station IDs.

  • The purpose of this study was to identify relationships between metacogintion, problem solving process, and debriefing experience in S-PBL. Study participants were 102 nursing students who took the integrated S-PBL class in their last semester. Data were collected using a self-reported questionnaire and analyzed into descriptive statistics, t-test, ANOVA, Pearson's correlation coefficient, and multiple regression. The highest subscale of debriefing experience was 'appropriate facilitator guidance' 3.78 (out of 5). Problem solving process and metacognition were positively correlated (r=0.704, p<.001). Metacognition was positively correlated with debriefing experience(r=0.197, p<.05), especially area of 'learning and making connections'(r=0.235, p<.05) whereas, there was no significant correlation between problem solving process and debriefing experience. Multiple regression (enter method) showed that gender and metacognition explained 51.2% of problem solving process. This study offers a rationale on simulation debriefing and further studies are needed to support effects of experiences of debriefing and factors on problem solving process and debriefing in nursing simulation.

  • Swelling behaviors of raw (Specimen-R) and compressed (Specimen-C) samples of maleic anhydride-grafted EPDM (MAH-g-EPDM) depending on the treatment with dichloroacetic acid were investigated. Structural characteristics of the samples were analyzed by nuclear magnetic resonance spectroscopy (NMR) and attenuated total reflectance-Fourier transform infrared spectroscopy (ATR-FTIR). When the samples were not treated with dichloroacetic acid, the swelling ratio of Specimen-R was greater than that of Specimen-C by about twice and the swelling ratio change was negligible though the process of swelling and drying was repeated. When the samples were treated with dichloroacetic acid, the first swelling ratios were increased but the second ones were decreased. For the Specimen-C, the swelling ratio of the sample without the dichloroacetic acid treatment and the second swelling ratio of the sample treated with dichloroacetic acid were nearly the same. However, for the Specimen-R, the second swelling ratio of the sample treated with dichloroacetic acid was strikingly lower than that of the sample without the dichloroacetic acid treatment. The swelling ratio change according to the dichloroacetic acid treatment was explained by dissociation of the existing crosslinks and formation of new crosslinks.

  • Total bacterial community DNA, which was extracted from microcosm soil and field soil after 2,4-D amendments, was analyzed on Southern blots, using the tfdA gene probe derived from plasmid pJP4 and the Spa probe from Sphingomonas paucimobilis. Southern blot analyses with total bacterial DNA extracted from soils Inoculated with Pseudomonas cepacia/pJP4 revealed that DNA probe method could detect the 2,4-D degrading bacteria down to $10^5\;cells/g$ dry soil. In the microcosm experiment, there was a good correlation between 2,4-D degradation and banding patterns in hybridization analyses performed after each 2,4-D treatment using the two probes. When bacterial DNA extracted from microcosm soil was hybridized with the Spa probe, a change in the position of hybrid bands was observed over time in a Southern blot, suggesting that population change or possibly genetic rearrangement in 2,4-D degrading microbial populations occurred in this soil. With the Spa probe, one hybrid DNA band was persistently observed throughout the five 2,4-D additions. When bacterial DNA isolated from the field soil was probed with the tfdA and Spa, strong hybridization signal was observed in the 100 ppm-treated subplot, weak signal In the 10 ppm-treated subplot, and no significant signal in the 1 ppm-treated and control subplots. The data show that DNA probe analyses were capable of detecting and discriminating the indigenous 2,4-D degrading microbial populations in soil amended with 2,4-D under laboratory and field conditions.
