  • This paper attempts to interpret the meaning of Mies van der Rohe's famous aphorism that "less is more" in terms of space. From his assertion that the art of building is the spatial execution of spiritual decisions, one can presume that his art of building was revealed through his spatial execution consciously guided by creative principles. One of his spatial principles was less is more a representative motto for the creation of sparsely furnished space with few objects and little perceptible architecture. After his awareness of an open plan, Mies intended to create less architecture by designing a minimal form of structural frames and maximum openness of open plans and glazed walls. This study posits that Mies created more potential space, for which he intended his open plans and neutral frames to be viewed as less. His building was designed to serve as the background of works of art and the changing nature outside so restrained its own existential voice in favor of the achievement of total harmony.

  • In the region of the intermediate open cluster M35 (NGC 2168), the time-series of V CCD images was taken for 12 nights from December 18, 2007 to September 25, 2010. From this observation, we detected 22 variable stars including 15 new ones. They are 6 $\delta$ Scuti, a Cepheid, an RR Lyrae, 9 eclipsing binaries and 5 semi-long periodic and/or slow irregular type variable stars. For the V photometry of the $\delta$2 Scuti stars, the multi-frequency analysis was performed using the Discrete Fourier Transform and the linear least-square fitting.

  • Ingestion of foreign body in children is a relatively common problem among paediatric population. The foreign bodies mostly pass spontaneously through the gastrointestinal tract. However, complications can occur according to its anatomical location, the characteristics of the foreign body, and delays in management. Although the cases of ingested button batteries or sharp objects impacted at the gastrointestinal tract can be very serious, there have been very only a few cases have reported colonoscopic removal of these dangerous foreign bodies in adults, and there have been no case reports in children. We report one case of a button battery and one case of an open safety pin, both impacted in the terminal ileum that had moved from the stomach within a few hours of ingestion and were eventually managed by colonoscopy without any complications.

  • Purpose: The purpose of this study was to examine the effects of prior information about ICU environment on the anxiety and environmental stress of cardiac surgery ICU patients. Methods: A non-equivalent control group non-synchronized quasi-experimental research design was used. Participants were 60 (control 30, experimental 30) patients who had been admitted to ICU. Prior information about the ICU environment was provided to the experimental group. The anxiety level of subjects was measured by State-Trait Anxiety Inventory (STAI) and the stress level of subjects was measured by the Intensive Care Unit Environmental Stressor Scale (ICUESS). Data were analyzed using a Chi-square test or a Fisher's exact test, independent samples t-test, and paired samples t-test. Results: There was no difference in Anxiety (t=-0.58, p=.563), but there was a significant difference in environmental stress (t=10.46, p<.001). Conclusion: Providing prior information would be an effective nursing intervention to reduce environmental stress.

  • Ice-going ships such as icebreakers, icebreaking tankers, and icebreaking LNG carriers are subjected to wave loads in open water and ice loads in ice-covered water. In terms of the ship's structural design, the local ice load is important. The fatigue failure due to repeated ice loads is also important. ISO 19906 specifies the assessment of the fatigue limit for a polar offshore structures. In addition, Lloyd's Register refers to fatigue damage based on ShipRight FDA ICE. In ShipRight FDA ICE, the fatigue damage indices due to wave and ice loads are simply presented as 0.5 for each load. It also states that the sum of the two fatigue damage indices should not exceed one. This study calculated and analyzed the fatigue damage index and fatigue life considering ARAON's voyage schedules and the assumed Antarctic voyage based on data measured during the Arctic voyage of ARAON in 2010.

  • Wire harness is a component for efficient control when electronic parts are required such as construction machinery and electric vehicles. With emerging issues such as autonomous driving and automation in construction, a wire harness composed of multiple cables has become an essential part because more electronic parts are required. However, when a wire harness failure occurs, systems can be stopped, accidents can occur, and economic damage can be significant. Therefore, in this paper, we developed a digital fault screening system that could easily and quickly diagnose faults in the wire harness. The principle of the developed system was to sequentially send pulse signals to the wire harness and use returned signals to perform fault detection. As a result of diagnosing faults using the developed failure detection system, a detection accuracy of 99.9 % was confirmed through the experiments.

  • Purpose: This study was conducted to explore the influence of academic institutional interest, open parent-adolescent communication, social (friend) support, and existential spiritual well-being on suicidal ideation of college students. Methods: The research design was descriptive survey research involving 285 college students in city G. Data was collected from May 18, 2011 to November 2, 2011 and analyzed using descriptive statistics, t-test, one-way ANOVA, Pearson correlation coefficient, and hierarchical regression analysis. Results: The findings reveal that suicidal ideation of college students was low, i.e., average score was $9.2{\pm}3.65$ (possible range 5~25). This study determined that suicidal ideation is negatively correlated with interest on the part of the academic institution, open parent-adolescent communication, social support from friends, and existential spiritual well-being. The extent of existential spiritual well-being was a significant predictor of suicidal ideation, controlling for general characteristics variables (gender, number of close friends, first supporter) and institutional interest, open parent-adolescent communication, and social support. Existential spiritual well-being accounted for 50% of the explanation of suicidal ideation of college students. Conclusion: Based on the outcomes of this study, designing an intervention program that emphasizes existential spiritual well-being in order to decrease suicidal ideation of tertiary education students is strongly recommended.

  • Purpose: We investigated early postoperative morbidity and mortality in patients with liver cirrhosis who had undergone radical gastrectomy for gastric cancer. Materials and Methods: We retrospectively reviewed the medical records of 41 patients who underwent radical gastrectomy at the Chonnam National University Hwasun Hospital (Hwasun-gun, Korea) between August 2004 and June 2009. There were few patients with Child-Pugh class B or C; therefore, we restricted patient selection to those with Child-Pugh class A. Results: Postoperative complications were observed in 22 (53.7%) patients. The most common complications were ascites (46.3%), postoperative hemorrhage (22.0%) and wound infection (12.2%). Intra-abdominal abscess developed in one (2.4%) patient who had undergone open gastrectomy. Massive ascites occurred in 4 (9.8%) patients. Of the patients who underwent open gastrectomy, nine (21.9%) patients required blood transfusions as a result of postoperative hemorrhage. However, most of these patients had advanced gastric cancer. In contrast, most patients who underwent laparoscopic gastrectomy had early stage gastric cancer, and when the confounding effect from the different stages between the two groups was corrected statistically, no statistically significant difference was found. There was also no significant difference between open and laparoscopic gastrectomy in the occurrence rate of other postoperative complications such as ascites, wound infection, and intra-abdominal abscess. No postoperative mortality occurred. Conclusions: Laparoscopic gastrectomy is a feasible surgical procedure for patients with moderate hepatic dysfunction.

  • It is very important to investigate air pollutants emissions emitted from open burning in order to control nonpoint sources effectively. In this study, we utilized incineration simulator proposed by U.S EPA and investigated emissions of CO, OC/EC, from household waste and biomass burning to estimate pollutant emissions by illegal incineration of biomass wastes. Emission factor of OC was estimated as 17.1 g/kg for rice strew, 23.5 g/kg for barley, 10.3 g/kg for corn stover, 4.3 g/kg for unseasoned wood, respectively. In case of EC, it was calculated as 1.6 g/kg for rice strew, 4.3 g/kg for barley, 1.4 g/kg for corn stover, 0.6 g/kg for unseasoned wood, respectively. Most of the pollutants emissions were emitted at the stage 1 and 2. In the stage 3, the pollutants concentration decreased gradually. To estimate emissions and build inventory for biomass burning, we need to know accurate activity data. We, therefore, used activity data of both survey results of previous study and statistical data of National Statistical Office. However, we need to perform additional experiments in the future to obtain more accurate activity data for various cases.
