  • 스마트폰의 보급에 따라 사용자간에 공유되는 정보가 점점 늘어나고 있다. 시간표 관리 시스템의 경우 과거에는 개별 사용자의 시간표를 관리하는 것이 주요 기능이었으나, 사용자간의 시간표를 비교함으로써 공통으로 가능한 비어있는 시간을 찾는 등 공유 기능에 대한 필요성이 증대되고 있다. 본 논문에서는 이화여대 학생들에게 특화된 편의성과 공유기능을 제공하는 시간표 관리 어플리케이션과 서버 프로그램을 설계하고 개발한다. 제공되는 편의성으로는 사용자가 자신의 시간표를 직접 입력하는 것이 아니라 이화 포탈(eportal.ewha.ac.kr)에서 내 시간표 정보를 자동으로 바로 받아 볼 수 있는 기능과 관련 교과목의 담당교수와 강의실 등의 추가적인 정보가 같이 저장되도록 하여 시간표 작성 시간이 획기적으로 줄일 수 있도록 한다. 또한 모든 사용자가 계정을 등록하여 타 사용자와 함께 듣는 수업과 공강 시간을 자동으로 계산해서 보여주는 공유 기능을 제공한다. 사용자 피드백을 통한 본 논문에서 개발된 시스템을 평가한 결과 편의성과 공유 기능에 만족함을 확인하였다.

  • LSGM$(La_{0.8}Sr_{0.2}Ga_{0.8}Mg_{0.2}O_{3-{\delta}})$ is the very promising electrolyte material for lower-temperature operation of SOFCs, especially when realized in anode-supported cells. But it is notorious for reacting with other cell components and resulting in the highly resistive reaction phases detrimental to cell performance. LDC$(La_{0.4}Ce_{0.6}O_{1.8})$, which is known to keep the interfacial stability between LSGM electrolyte and anode, was adopted in the anode-supported cell, and its effect on the interfacial reactivity and electrochemical performance of the cell was investigated. No severe interfacial reaction and corresponding resistive secondary phase was found in the cell with LDC buffer layer, and this is due to its ability to sustain the La chemical potential in LSGM. The cell exhibited the open circuit voltage of 0.64V, the maximum power density of 223 $mW/cm^2$, and the ohmic resistance of $0.17{\Omega}cm^2$ at $700^{\circ}C$. These values were much improved compared with those from the cell without any buffer layer, which implies that formation of the resistive reaction phases in LSGM and then deterioration of the cell performance is resulted mainly from the La diffusion from LSGM electrolyte to anode.

  • Over the past few decades, drug regulatory agencies in advanced countries have been emphasizing pharmacometrics as a tool for an effective and efficient drug evaluation. Despite this international movement, the value of pharmacometrics is still poorly recognized by the Korean drug evaluation system. This study aimed to analyze the current state of utilization of pharmacometrics by foreign drug regulatory agencies and develop a road map to guide the implementation pharmacometrics into the Korean drug evaluation system. MEDLINE and foreign drug regulatory agency database were extensively searched to obtain scientific research articles, guidance, regulations and pharmacometric review reports on foreign pharmacometric drug evaluation system. A systematic roadmap comprised of 3 stages to implement pharmacometrics in Korean drug evaluation system was formulated after analyzing the collected data in tune with the current evaluation system. Pharmacometrics is an urgently required tool to achieve an efficient drug evaluation and review in Korea. The road map developed by this study is expected to aid in setting up a policy to implement and utilize pharmacometrics in Korea.

  • Primary ciliary dyskinesia (PCD) is characterized by the congenital impairment of mucociliary clearance. When accompanied by situs inversus, chronic sinusitis and bronchiectasis, PCD is known as Kartagener syndrome. The main consequence of impaired ciliary function is a reduced mucus clearance from the lungs, and susceptibility to chronic respiratory infections due to opportunistic pathogens, including nontuberculous mycobacteria (NTM). There has been no report of NTM lung disease combined with Kartagener syndrome in Korea. Here, we report an adult patient with Kartagener syndrome complicated with Mycobacterium abscessus lung disease. A 37-year-old female presented to our hospital with chronic cough and sputum. She was ultimately diagnosed with M. abscessus lung disease and Kartagener syndrome. M. abscessus was repeatedly isolated from sputum specimens collected from the patient, despite prolonged antibiotic treatment. The patient's condition improved and negative sputum culture conversion was achieved after sequential bilateral pulmonary resection.

  • Background : The purpose of this study was to investigate the effects of taping on the neck rotation angle in the elderly. Methods : The twenty-eight elderly aged over 60 and twenty-seven college students participated in the study. In both groups, neck rotation angles were measured through CROM before and after taping. SPSS 18.0 was used for data analysis. Results : The results indicated that both groups showed significant increases in the neck rotation angles of the affected side after taping. However, there was no significant difference in the rotation angle of both neck regions after taping. The variation of the student group was higher than that of the elderly group after taping. Conclusion : We think that taping can be effective in balancing the neck muscles of both sides and in increasing the rotation angle of the neck.

  • Purpose: Our study aimed to evaluated sex differences in clinical features of obese high school students. Methods: One hundred three obese high school students (body mass index [BMI]${\geq}$85th percentile) and 51 control students (BMI<85th percentile) were enrolled in this study. Anthropometric measurements were performed. Fasting serum glucose, insulin, aspartate aminotransferase, alanine aminotransferase, total cholesterol, triglyceride, low-density lipoprotein cholesterol (LDL-C), high-density lipoprotein cholesterol (HDL-C), and high-sensitive C-reactive protein were measured. Abdominal fat thickness, degree of fatty liver, and carotid intima-media thickness were measured by ultrasound. Results: In control and obese groups, waist circumference was significantly longer in boys but body fat mass was Significantly higher in girls. In the control group, total cholesterol and LDL-C were higher in girls. In the obese group, however, aspartate aminotransferase, alanine aminotransferase and triglyceride were higher and HDL-C was lower in boys. Preperitoneal fat thickness was significantly higher in obese girls. In obese group, the degree of fatty liver was significantly higher in boys. Carotid intima-media thickness was not significantly different between boys and girls. Conclusion: Obese adolescents had distinguishable sex differences in body measurements, metabolic abnormalities, abdominal fat thickness and fatty liver. We can infer that these characteristics may extend into adult obesity.

  • Mycobacterium avium subsp. paratuberculosis is the pathogen of paratuberculosis called Johne's disease. Johne's disease is hardly eliminated because of its long latent period and continuous dissemination, so it is found in ruminants worldwide and can cause substantial economic losses in cattle. It has been reported in many studies on the distribution of Johne's disease in some provinces of Korea that not many, but noticeable numbers of infected cows have been detected since the first detection in 1984. The aims of this study was to investigate the prevalence of Johne's disease obtained from slaughtered cattle in central area of Gyeongnam province, Korea. In this study, the ELISA serum antibody test and PCR were employed on a total of 240 blood and ileac substrate samples from slaughtered cattle in two slaughtering and wholesale centers in Gyeongsangnam-do Livestock Veterinary Research Institute Central Branch. Out of the entire 240 blood samples, three (1.3%) were positive by ELISA, while five (2.1%) were suspected cattle. But ileac substrate samples, eight (3.3%) were positive by PCR. By breeds, positive rates of ELISA and PCR in Korean native cattle were 1.3% and 3.5%, respectively, but no positive cows were found in dairy cattle. By provinces, sero-positive rates of Gyeongnam and Gyeongbuk were 1.6% and 1.3%, respectively. And PCR positive rates of Gyeongnam, Gyeongbuk and other provinces were 2.4%, 5.0% and 2.8%, respectively. These results indicate that it requires the nationwide monitoring test and measure to deal with subclinically infected slaughtering cows.
