웹을 기반으로 하는 e-러닝은 다수의 학습자에게 쉽고 빠르게 학습을 제공할 수 있다는 장점으로 효과적인 학습 지원 수단으로 각광받고 있다. 그러나 대다수의 e-러닝은 일률적인 학습 방법과 내용을 일방적으로 제공하는 공급자 중심의 구조라는 한계를 가지고 있는 실정이다. 이러한 문제를 해결하기 위해 시간과 공간의 제약 없이 학습자가 원하는 방식과 내용으로 학습할 수 있는 u-러닝에 대한 연구가 이루어지고 있으나 대부분은 유비쿼터스 시스템적인 측면에서의 연구가 이루어지고 있을 뿐이다. 본 연구에서는 학습자 중심의 u-LMS 모델 개발을 위하여 학습자의 특징 및 요구사항, 그리고 이를 지원하기 위한 기술적 환경 등에 대한 분석을 토대로 이를 구체화시키기 위한 전략과 관점, 그리고 시스템으로의 전개를 위한 아키텍처로 구성하였다. 또 이러한 아키텍처 레이어에 기반한 컴포넌트 구성과 핵심 프로세스 및 개념적인 클래스 모델을 함께 제시함으로서 향후 시스템 설계시 참조할 수 있도록 하였다. 본 연구의 결과는 요구사항 적합도를 중심으로 전문가 설문을 통해 그 유효성이 검증된 바, 향후 u-LMS를 기반으로 하는 u-러닝 시스템의 계획 및 운영을 위한 전략과 관점뿐만 아니라, 실제 적용을 위한 기초 설계에 유용한 참조가 될 것으로 기대한다. Web-based e-Learning has the advantage of providing many learners with good quality contents quickly and easily, so it is highlighted as an effective learning support way. Nevertheless, many e-Learning systems are limited in the supplier-centered structure that provides uniform ways and contents one-sidedly. To solve this problem, the studies about u-Learning to study with the ways and contents learners want have been made without time and space constraints, but most of the studies are made in the systematic aspect. In this paper, for developing learner-centered u-LMS model, we analyze characteristic and requirement of learners and a technical environment for supporting them, and then we make the model consists of the strategies and aspects for implementing the analyses and architecture for the system. In addition, we present component construction based on this architecture layer and the core process and conceptual class model in order to refer to the further system design. This paper’s results verify the suitability and availability of model through an expert questionnaire in suitability of requirement, so we anticipate the strategies and aspects for the plan and operation of the u-Learning system based on u-LMS, and the references to the basic design for the practical application.

본 연구는 암 진단 시점 환자의 외상후 스트레스를 초기에 사정하고 중재하여 스트레스를 적게 느끼면서 안정을 되찾을 수 있는 사회적 지지 방법을 탐구하여 암환자의 삶의 질을 향상시키는 간호를 제공하고자 시도하였다. 암 진단 받고 수술 전후에 입원한 환자 134명을 대상으로 구조화된 질문지를 이용하여 자료를 수집하였고, 수집된 자료는 중다회귀분석방법을 이용하여 분석하였다. 연구 결과, 가족지지, 친구지지, 그리고 특별(의료인)지지가 높을수록 암 진단 초기환자들의 외상후 스트레스는 낮아지는 것으로 나타났다. 외상 후 스트레스의 감소에 가장 큰 영향을 미치는 사회적지지 유형은 특별(의료인)지지였으며, 그 다음으로 가족지지, 친구지지의 순으로 나타났다. 따라서 암 진단 초기부터 환자와 가족을 동시에 지지 해주는 중재, 그리고 암환자의 특성상 완치되거나 질병이 진행되어도 신체뿐만 아니라 정신적인 문제에도 영향을 미치므로 병의 진행 단계를 고려한 종단적인 지지 프로그램과 간호중재의 개발이 요구된다. This study attempted to provide nursing that improves the quality of life for cancer patients by exploring social support methods for recovering stability with less stress by initially assessing and mediating the post-traumatic stress of patients at the time of cancer diagnosis at the stages. The data were collected using structured questionnaires of 134 patients who were diagnosed as cancer and hospitalized before and after surgery. The collected data were analyzed using multiple regression analysis. Data collected were analyzed using multiple regression analysis. The results of this study showed that the higher the family support, friend support, and special support, the less the post-traumatic stress disorder. Based on the analysis of results, the intervention that simultaneously supports the patients and family members from the beginning of the patients’ cancer diagnosis and a continuous support program and nursing intervention in consideration of the ongoing disease were confirmed to be necessary.

Purpose: This study aimed to examine the changes in stress, occupational stress, and subjective health problems of novice female nurses within the first 18 months of work. Methods: This was a longitudinal study conducted with a secondary data analysis based on the Shift Work Nurse’s Health and Turnover (SWNHT) study. The participants were 178 female novice nurses who participated in all 3 data collection activities (on the first day of orientation before ward placement [T0], 6 months after work [T1], and 18 months after work [T2]). The stress, occupational stress, 8 subjective health problems (upper musculoskeletal pain, leg/foot discomfort, depression, anxiety or emotional disorder, sleep disturbance, headache, gastrointestinal disorder, menstrual disorder, and others), and the greatest health problem during the study period were measured, respectively. Data were analyzed using SPSS 26.0 to obtain descriptive statistics. Results: The subjective health of novice female nurses were found to be poor at T1 compared to T0 on both physical (upper musculoskeletal pain, leg/foot discomfort, and sleep disturbance) and psychological health problems (depression and stress). However, the psychological health problems of the participants were alleviated at T2 whereas; physical health problems persisted until T2. Conclusion: Novice nurses had poor health problems 6 months after work. Sleep disturbance and musculoskeletal pain persisted although other health problems such as depression and stress were alleviated over the period. Strategies to prevent and manage different health problems of novice female nurses at different work duration are urgently needed.

Pyriform sinus perforation is a rare complication of endotracheal intubation. It most commonly occurs at the hands of the less experienced physician in emergency situations. It can occur after traumatic intubation and is potentially lethal. The site most commonly perforated is the pharynx, posterior to the cricopharyngeal muscle; the second most common site is the pyriform sinus. We report a case of pyriform sinus perforation after endotracheal intubation, which was successfully treated with primary closure.

Background and Objectives Various tumor markers have been studied in an attempt to evaluate and decide the optimal treatment of the patients with head and neek squamous cell carcinoma (HNSCC). A nuclear antigen Ki-67 is a proliferative marker of tumor cells in all phases of cell cycle except G0. c-met gene, the tyrosine kinase receptor for hepatocyte growth tactor, may play various roles in malignant transformation. The authors evaluated the prognostic significance of Ki-67 and c-Met in surgical specimens of HNSCC to determine the relationship with the various clinicopathological characteristics. Materials and Methods Formatin-fixed paraffin-embedded surgical specimens were obtained from 54 patients with HNSCC. Ki-67 and c-Met expressions were analyzed by immunohistochemical staning and were compared with the clinicopathological characteristics such as, pathologic differentiation, tumor stage, clinical stage and lymph node metastasis. Results Ki-67 and c-Met over-expression was detected in 66.7% and 90.7% in HNSCC. There was positive correlation of increased expression of Ki-67 with tumor stage. and clinical stage, increased expression of e-Met with tumor stage, clinical stage, and nodal status. The expression of c-Met had a significant positive relationship with Ki-67 index (p<0.05). Conclusion Therefore, Ki-67 and c-Met are useful markers of tumor progression, aggressiveness and prognosis in HNSCC.

Recently, dental implant is frequently performed in dentistry. It can give rise to complications such as maxillary sinusitis, oroantral fistula, displacement of implants and others. Among these complications, maxillary sinusitis is one of the severe complication, which is being reported to occur rarely. The complications of dental implant are often accompanied by gingival swelling, pain, fistula and other symptoms, for which immediate therapeutic measures may be implemented. The clinical diagnosis of sinusitis after dental implant is confirmed by radiologic findings and clinical symptoms. It can be treated with medical and surgical therapy. The authors experienced a case with unilateral maxillary sinusitis developed after dental implant performed at the dental clinic, which was alleviated by performing endoscopic sinus surgery. By reporting this case, we aimed to call attention to the complications of sinusitis and consider implant displacement in suspicious cases of acute maxillary sinusitis.
