  • The purpose of this study is to analyze the effect of sunshine on the heating energy consumption of apartment houses by a field investigation in Haeundae, Busan. In the field, heating energy consumption of every household is researched by reading a calorimeter and the duration of sunshine of every household is calculated by Sunlight V1.0. Then, the duration of sunshine and heating energy are done regression analysis by SPSS 10. According to this study the apartment houses by orientation spend more energies order of east, west, southeast, southwest, and south. When apartment houses are same orientation, there is difference of $29{\sim}58\%$ in heating energy consumption by the duration of sunshine. And the heating energy consumption in worst condition of sunshine increases $67\%$ on the best condition of sunshine.

  • 현지해안의 해빈변형을 연구하기 위해 해운대 해수욕장에서 파랑과 해빈류를 관측하였으며, 또한 파랑과 흐름의 간섭효과를 고려한 파랑변형 및 해빈류를 수치계산하여 관측결과와 비교하였다. 지형변동은 경험적 고유함수법에 의해 해석했다. 해운대 해수욕장의 해빈변형을 해빈류의 유황과 지형변동의 해석결과에 의해 분석하였다. 남서풍이 탁월할 때는 종단방향의 표사이동에 의해 침식이 일어났으며, 이 때의 표사이동 양상은 입사각이 180。일 때의 해빈류의 유황과 거의 일치하였다. 북동풍이 탁월할 때는 연안방향의 표사이동에 의해 침식이 일어났으며, 이 때의 표사이동 양상은 입사각이 160。일 때의 해빈류의 유황과 거의 일치하였다. 즉, 현지의 해빈변형은 입사파의 특성과 파랑에 의해 일어나는 해빈류에 의해 크게 좌우되는 것으로 나타났다.

  • This study aimed at framing alternative urban planning scenarios reflecting urban planning factors, performing urban climate simulation and evaluating eco-friend and low energy characteristics of each scenario on the viewpoint of urban temperature and energy savings on the target of the costal city including Haeundae District in Busan The results are as follows. 1)The fact that urban higher temperature is approximately 2.5 times higher in the building constructed area than whole urban area was represented severe higher temperature phenomenon in the built-up area. Ground greening, water scenario and soil scenario could be expected peek air temperature alleviating effect in order. Especially water scenario had significant effect(maximum $2.5^{\circ}C$) on lowering of air temperature.

  • Lateral epicondylitis with rupture of the radial collateral ligament of the elbow has not been reported in the literature. We report on a case of a recreational golfer who had not received steroid injection and had no trauma history. The patient was treated with open surgical repair. At 2 years follow-up, satisfactory clinical and radiological outcomes were observed with return to pre-injury level. The authors report this case and review the literature.

  • The shoreline changes were observed and analysed using the video image by a remote unmanned automatic camera monitoring system installed at Haeundae beach of Busan City. In order to analyse quantitatively the shoreline changes caused by waves and tides, the image averaging technique and the rectification technique for obliquely acquired image were applied to the video image during the typhoon Bart in September, 1999. The results showed that the camera monitoring system can be used as a very cost effective and efficient tool for monitoring shorelines which change continuously due to waves and tides.

  • Purpose: As the number of total knee arthroplasties (TKAs) increases, the incidence of femoral periprosthetic fractures after TKA is also increasing. This review aimed to suggest a new surgically oriented classification system for femoral periprosthetic fractures. Methods: We investigated the classifications, and current treatment trends for femoral periprosthetic fractures after TKA by means of a thorough review of the relevant literature. Results: Numerous studies reported good results of surgical treatment with modern fixatives including locking compression plates and retrograde intramedullary nails. However, few classifications of femoral periprosthetic fractures reflect the recent developments in surgical treatment. Conclusions: We recommend that surgical management be considered the first-line treatment for femoral periprosthetic fractures after TKA. Our new classification will help in deciding the surgical treatment option for femoral periprosthetic fractures after TKA.

  • Camera monitoring data for 5 years from January 2009 to January 2014 are analyzed to investigate changes in beach erosion on Sangju, Gujora and Haeundae beaches on the South sea and Jungmun beach on the south shore of Jeju Island. The data show the time series of beach area changes obtained from digital orthoimages rectified from oblique images taken near the beaches by cameras. Each beach has different sediment sizes and shapes, but faces the South and is eroded mainly during Typhoons. However, each beach often responds differently to the same Typhoon, and some beaches outside the influence of the Typhoon are also eroded. This study shows that high frequency data of beach area changes obtained from cameras can effectively analyze the seasonal changes in beach area.

  • Purpose : This study identified the factors affecting the clinical competence of emergency unit nurses caring for foreign patients. Methods : This study utilized a descriptive correlation design. Participants were 112 emergency unit nurses working in different hospitals designated as the government's emergency medical centers and agencies in 2018. The collected data were analyzed using descriptive statistics, independent t-test, one-way ANOVA, Pearson's correlation coefficients, and multiple linear regression analysis. Results : Subjects' clinical competence showed positive relationships with cultural competency (r=.45, p<.001) and intercultural communication (r=.53, p<.001). Factors that affect the clinical competence of subjects showed intercultural communication (β=0.38, p=.001). Conclusion : It is necessary to develop programs to improve intercultural communication, factors that influence clinical competence of emergency unit nurses, and apply them to practical fields.

  • Facial diplegia (FD) rarely occurs as a regional Guillain-Barré syndrome (GBS) variant. A 70-year-old male presented with bifacial weakness that had started on the left side and extended to the right after several days. He was then treated using steroids and gradually improved. Serum antiganglioside antibody testing revealed positivity for anti-GM1 IgG antibodies. FD can be idiopathic, but it is an uncommon GBS variant. The ganglioside antibody test may increase the possibility of diagnosing isolated FD.

  • The effect of the parameters for few-layered graphene growth by thermal CVD on nickel substrate was investigated. Graphene can be synthesized by using different strategies. Chemical vapor deposition (CVD) has known as one of the most attractive methods to produce graphene due to its good film uniformity, compatibility and large scale production. The control of parameters such as temperature, growth time and pressure in CVD process has been widely recognized as the most important process in graphene growth. Different carbon precursors, methane and acetylene, were introduced in the quartz tube with a variety of growth conditions. Raman spectroscopy was used to confirm the presence of a few- or multi-layered graphene.
