This study was a descriptive research that attempted to provide the basis for improving cultural competence by identifying the effect of multicultural awareness and cultural empathy on the cultural competence of nursing students. The subjects were nursing students from grades 1 to 4 who were enrolled in two nursing colleges in Gwangju and Chonnam. The data were collected from September to December 2018. The 201 data collected were analyzed by descriptive statistics, t-test, ANOVA, Pearson's correlation coefficient, and multiple regression analysis with SPSS 25.0 for windows. Multicultural awareness(r=.451, p<.01) and cultural empathy(r=.582, p<.01) had high positive correlations with cultural competence. The factors that affected the cultural competence were cultural empathy(β=.422, p<.001) and multicultural awareness(β=.222, p<.001) order. The explanatory power of these factors was 40.5%. These findings suggest that in order to promote the cultural competence of nursing students, strategies to promote multicultural awareness and cultural empathy should be developed, and these strategies should focus more on cultural empathy than on multicultural awareness.

Objective : Fixation of the C1-2 segment is challenging because of the complex anatomy in the region and the need for a high degree of accuracy to avoid complications. Preoperative 3D-computed tomography (CT) scans can help reduce the risk of complications in the vertebral artery, spinal cord, and nerve roots. However, the patient may be susceptible to injury if the patient's anatomy does not match the preoperative CT scans. The intraoperative 3D image-based navigation systems have reduced complications in instrument-assisted techniques due to greater accuracy. This study aimed to compare the radiologic outcomes of C1-2 fusion surgery between intraoperative CT image-guided operation and fluoroscopy-guided operation. Methods : We retrospectively reviewed the radiologic images of 34 patients who underwent C1-2 fusion spine surgery from January 2009 to November 2018 at our hospital. We assessed 17 cases each of degenerative cervical disease and trauma in a study population of 18 males and 16 females. The mean age was 54.8 years. A total of 139 screws were used and the surgical procedures included 68 screws in the C1 lateral mass, 58 screws in C2 pedicle, nine screws in C2 lamina and C2 pars screws, four lateral mass screws in sub-axial level. Of the 34 patients, 19 patients underwent screw insertion using intraoperative mobile CT. Other patients underwent atlantoaxial fusion with a standard fluoroscopy-guided device. Results : A total of 139 screws were correctly positioned. We analyzed the positions of 135 screws except for the four screws that performed the lateral mass screws in C3 vertebra. Minor screw penetration was observed in seven cases (5.2%), and major pedicle screw penetration was observed in three cases (2.2%). In one case, the malposition of a C2 pedicle screw was confirmed, which was subsequently corrected. There were no complications regarding vertebral artery injury or onset of new neurologic deficits. The screw malposition rate was lower (5.3%) in patients who underwent intraoperative CT-based navigation than that for fluoroscopy-guided cases (10.2%). And we confirmed that the operation time can be significantly reduced by surgery using intraoperative O-arm device. Conclusion : Spinal navigation using intraoperative cone-beam CT scans is reliable for posterior fixation in unstable C1-2 pathologies and can be reduced the operative time.

Purpose - As more low cost carriers are introduced, the competition between the low cost carriers to become the nation's leading low cost carrier is also being intensified. The purpose of this study is to select various choice attributes for low cost carrier and figure out important factors that customers take into account for low cost carrier selection. The study also involves in establishing the relationship between perceived value, customer satisfaction, and customer behavior Intention, in an effort to identify choice attributes that are important to customers' low cost carrier. Research design, data, and methodology - To examine these research models, samples were collected from 247 peoples who visited In-Cheon international Airport during June, 2017. Results - The results of the study showed that, 'reservation service', 'airport service', 'in-flight service', and 'price' services have a significant effect on the perceived value of the choice attributes. While 'reservation service', 'airport service', 'in-flight service', and 'flight operation service' have a significant effect on the customer satisfaction of the choice attributes, perceived value has a significant effect on customer satisfaction. Perceived value has a significant effect on customer behavior intention. Finally, customer satisfaction has a significant effect on customer behavior intention. Conclusions - Flight operation service has no significant effect on perceived value of the choice attributes of low cost carriers, which indicates that the low cost carriers have not yet been well-established in the flight operation service sector. It seems likely that low cost carrier will be able to gain a competitive advantage over other companies if they expand their routes and improve the convenience of flight connections. In addition, the results show that the price service does not have a significant effect on customer satisfaction of the choice attributes of low cost carriers. From this, we may assume that the airline ticket prices of low cost carriers are already low, and the price cannot be a deciding factor in the competitive advantage of low cost carriers. To achieve higher customer satisfaction of the choice attributes, companies should strengthen the competitiveness of 'reservation service', 'airport service', 'in-flight service', and 'flight operation service'.

Acaiberry (Euterpe oleracea Mart.) is widely diffused in amazon and is known that has high antioxidant capacity and potential anti-inflammatory activities. The aim of this study was to evaluate analgesic effects of acaiberry in formalin-induced orofacial pain through p38 mitogen-activated protein kinases (p38 MAPK) and nicotinamide adenine dinucleotide phosphate 4 (NOX4) pathway. Rats were divided into 5 groups (n=6); formalin (5%, $50{\mu}L$), formalin after saline (vehicle) or acaiberry (16, 80, 160 mg/kg, intraperitoneally). The nociceptive response was investigated all of groups, p38 MAPK or NOX4 were analysed at dose of 80 mg/kg of acaiberry in rat's medulla oblongata and adrenal gland. Results indicated that acai berry produced analgesic effect in a dose-dependent manner and significantly reduced formalin-induced nociceptive response at 15~40 min. Acaiberry (80 mg/kg) decreased the increased p38 MAPK activation and NOX4 expression in medulla oblongata and adrenal gland. Based on these results, acaiberry is believed to be useful for modulation of orofacial pain and its treatments because of its anti-inflammatory and antioxidative effects.

Respiratory failure is the most serious manifestation and usual cause of death in acute organophosphate poisoning, and is common in acute cholinergic crisis. But the respiratory failure may appear suddenly in a patient who is recovering from the cholinergic crisis, even while receiving conventional therapy. These are case report of 37 years old male and 24 years old female with intermediate syndrome in organophosphate poisoning. The two patients ingested organophosphate(fenthion and mixture of DDVP with chlorpyrifos respectively) incidentally and in a sucide attempt respectively. After apparent recovery from the cholinergic crisis with a conventional therapy but before the expected onset of delayed polyneuropathy, the respiratory failure appeared suddenly with a muscular weakness, affecting predominantly the proximal limb muscles, neck flexors, territories of several motor cranial nerves. The two patients needed mechanical ventilatory support and recovery from the intermediate syndrome was complete in both patients, although one subsequently developed hypoxic encephalopathy. The clinical manifestation and electrophysiologic study support the clinical diagnosis of intermediate syndrome. The syndrome carries a risk of death. because of respiratory paralysis, if not recognized early and treated adequatedly. Prompt endotrachial intubation and mechanical ventilatory support is the cornerstone of treatment of the intermediate syndrome. Therefore, all patient should be observed in a hospital for up to 5 days after poisoning.

Microscopic analysis has been performed in order to investigate effects of the microstructure of the starting feed rods on the morphology of the S-L interface and the stability of the molten zone during single crystal growth of $SrTiO_{3}$ using a floating zone method. Undoped and $Fe_{2}O_{3}$ doped $SrTiO_{3}$ doped $SrTiO_{3}$ specimens, sintered at the different temperatures have been used. In the case of the feed rods sintered at the lower temperature($1400^{\circ}C$), the poor densification made the stability of the molten zone difficult to maintain. The feed rods sintered at the higher temperature ($1600^{\circ}C$) exhibited the higher density but their molten zone was difficult to maintain due to the presence of the abnormally grown grains. It is concluded that the uniform grain size distribution of the feed rod is the critical factor to maintain the stable molten zone and therefore to give optimum growth condition during FZ single crystal growth.

In recent years, the proportion of youth's self-employed is steadily increasing, and government policy also actively encourages youth to become an entrepreneur. However, most of the domestic precedent studies on the self-employed labor market focus on the middle-aged and the elderly, and previous studies on the self-employed labor market of young people are hardly ever studied. Above all, the study that examines the factors of entry into self-employment of young people is not sufficient and researchers usually utilize the study about for all ages to explain the self-employment market of young people. However, because the young and middle-aged people differ in labor market conditions, family backgrounds, and the level of accumulation of human capital, separate explanations and theories are needed. Therefore, this study explored the factors of entry into self-employment by separating the age group from 15~29 years old. The data used in the analysis was the 9th to 20th data of the Korea Labor Panel Survey. The youth unemployment rate and employment rate were referred to the Economically Active Population Survey of Statistics Korea. The analysis subject was limited to young people who are currently performing economic activities, and the analysis method used multi-level logit model. The main results are summarized as follows. First, the lower the unemployment rate and the higher the employment rate, the younger people tend to enter their own businesses on the structural level. Second on the individual level, young people who possess enough financial capital or pursuit personal aptitude or interest tend to enter self-employment. However, there are no statistical effects of human capital and entrepreneur capital.

In the previous paper (Kim et al., Glycoconjugate Journal 16, 247-252, 1999), heteropolysaccharides from Korean medicinal plant, Phellodendri cortex (Hwangbek) showed a poten B-Iymphocyte-stimulating activity in a system using polyclonal antibody forming cells in C57BL/6XC3H mice at dosages of 2-10 mg. In a series of biolgical active polysaccharides from natural medicinal plants, the polysaccharide fractions were isolated and purified from Phellodendron chinese SCHNEID, and antitumor activities were examined at dosages of 2, 5 and 10 mg/100 g. F-7 and F-8 showed the highest tumor inhibitory activities (inhibition ratio 96.4 and 98.2% in 2 mg/100 g), and in dose of 5 mg/100 g, the inhibitory ratios were 95.3 and 97.5%, respectively. Furthermore, 10 mg/100 g of intraperitoneal (i.p.) injection gave 97.3 and 98.7% of inhibition. In oral administration, the inhibitory activities were not markedly observed, indicating that the polysaccharides are directly acting to immune system. When the effects on TS and TK activities were determined, TS activities in the F-2 and F-7-treated mice were markedly suppressed to 73.7% and 79.5% of that in the control (p<0.01), while there was little difference in TK activity with a slight decrease in F-2 only. However, in i.p. injection, TS activities in the F-2, F-5, F-7 and F-8-treated mice were markedly suppressed to 83% to 85% of that in the control (p<0.01). Furthermore, there was also significant differences in TK activities in F-2, F-5, F-7 and F-8-treated mice (p<0.05). Therefore, polysaccharide fraction F-8 was further purified to active fractions of F-9 and F-11 by gel permeation chromatography using TSK Gel HW50S. The purified polysaccharides of F-9 and F-11 were composed of GlcNAc (47.3%), Gal (24.7%) and Man (28.0%). These results clearly indicated that the i.p. injection is much effective to suppress tumor growth than oral administration.

80년대 초 GIS의 개념이 국내에 도입된 후, 1988년 대구광역시를 필두로 지자체의 GIS 구축이 시작되어 국가에서는 GIS 구축의 체계적인 관리의 필요성에 따라 1995년 제1차 국가GIS 기본계획을 수립하고, 2000년 ‘국가지리정보체계의 구축 및 활용 등에 관한 법률’을 제정, 공포하여 각 지자체의 실정에 맞는 GIS 기본계획을 수립하도록 유도하고 있다. 그러나, 바람직한 지자체 GIS 기본계획 작성의 표준이 제시되지 않아 지자체 GIS 기본계획이 개인의 안목이나 타 지자체의 내용을 참조로 만들어져 형식적이고 획일적인 결과물이 산출되고 있다. 그리하여 기존에 수립된 지자체 GIS 기본계획이 일부의 지자체를 제외하고는 해당 지자체의 GIS 구축 사업에 활용되지 못하고 책장속의 책으로 존재하고 있다. 따라서, 본 논문의 목적은 지자체 GIS 기본계획 표준안을 제시하여 향후 해당 지자체에서 GIS 기본계획을 수립할 때, 구성적인 측면의 틀을 제공하여 일정수준을 만족할 수 있는 지자체 GIS 기본계획의 수립을 지원하고자 한다. 지자체 GIS 기본계획 표준(안)을 도출하기 위해서 정보화전략계획과 해외 관련 연구, 국가GIS 기본계획의 검토를 통하여 지자체 GIS 기본계획의 구성요소를 도출하고, 기존지자체 GIS 기본계획의 목차를 중심으로 분석하여, 문제점을 도출하고, 그에 따른 시사점을 제시하여 지자체 GIS 기본계획 표준(안)의 기반이 되도록 하였다. 제안된 지자체 GIS 기본계획 표준(안)은 향후 각 지자체의 활용가치가 높은 GIS 기본 계획의 수립에 도움이 될 수 있도록 하며, 나아가서는 수립된 지자체 GIS 기본계획이 지자체의 성공적인 GIS 구축을 유도하는 가이드의 역할을 수행할 것으로 기대된다.가 있다. 본 연구의 결과를 통해 지방자치단체 GIS 기본계획에 있어 조직 측면의 장기적 비전의 제시가 가능하며 이를 통해 보다 성숙된 GIS 사업의 추진과 효율적인 시스템의 운영이 가능할 것이다.. 이상의 결과를 종합해볼 때, ${\beta}$-glucan은 고용량일 때 직접적으로 또는 $IFN-{\gamma}$ 존재시에는 저용량에서도 복강 큰 포식세로를 활성화시킬 뿐 아니라, 탐식효율도 높임으로써 면역기능을 증진 시키는 것으로 나타났고, 그 효과는 crude ${\beta}$-glucan의 추출조건에 따라 달라지는 것을 알 수 있었다.eveloped.

There are much damage of people and property because of heavy rain every year. Especially, there are problem to major facility such as dam, bridge, road, tunnel, and industrial complex in the ground stability. So the counter plan for landslide or ground failure must be necessary In the study, the technique of regional landslide susceptibility assessment near the Ulsan petrochemical complex and Kumgang railway bridge was developed and applied using GIS. For the assessment, the geological structures such as bedding and fault were surveyed and the geological structure, topographic, soil, forest, and land use spatial database were constructed using CIS. Using the spatial database, the factors that influence landslide occurrence, such as slope, aspect, curvature and type of topography, texture, material, drainage and effective thickness of soil, type, age, diameter and density of forest, and land use were calculated or extracted from the spatial database. For application of geological structure, the geological structure line and fault density were calculated. Landslide susceptibility was analyzed using the landslide-occurrence factors by probability method that is summation of landslide occurrence probability values per each factors range or type. The landslide susceptibility map can be used to assess ground stability to protect major facility.
