Asthma is a disease of the airways that is characterized by increased responsiveness of the tracheobronchial tree to a multiplicity of stimuli. A number of causes have been postulated for the increased airway reactivity of asthma is conservative as beta-adrenergic agonist, methylxanthines, glucocorticoids, anticholinergics and mast cell stabilizing agent. Stellate ganglion block for the treatment of bronchial asthma has its controversies. Stellate ganglion block was performed for the treatment of 3 patients with bronchial asthma. After stellate ganglion blocks, dyspnea, coughing and wheezing was markedly reduced. Lung function test improved with 1 st case. Two asthma cases were able to discontinue medication for asthma. No severe aggrevation of bronchial symptoms were noted after stellate ganglion blocks. It suggested that stellate ganglion block can be safely performed on bronchial asthmatic patients.

By no means rapid advances in technology affects the working and improvement of all systems built to increase the quality/standards of human living. Information technologies as the main driving force of technological progress today happen to be a sine qua non for all organizations hoping to keep pace with or surpass rivals. However, despite their vital advantages it is true that these create undesirable side effects that harm social systems and the rights of persons. Similar to all others in the world Turkey is trying to cope with the problem through creating an appropriate legal and administrative substructure trusted to discontinue or at least minimize such criminal acts.

A Twisting machine is to twist yarns for improving yarn stiffness. After twisting yarns, the twisting machine is winding yarn at a bobbin. Traverse cam is main part of winding yarn part. In other to improve twisting machine performance and stability, improve traverse cam part. Original displacement curves of traverse cam has two problems. One is that displacement curve has a vertex point the other is that velocity curve is discontinue point. So that, in this paper proposes a modified displacement curves of traverse cam and new shape design method of the traverse cam using the relative velocity method[1]. The relative velocity method calculates the relative velocity of the follower versus the cam at a center of roller, and then determines a contact point by using the geometric relationship and the kinematical constraints. Finally, we present to compare two designed cam. One is designed using original displacement curves the other is using modified displacement curve.

본 논문에서는 플라이백 마이크로 인버터를 통해 전류센서 없이 최대전력 추종(Maximum Power Point)방법을 제안한다. 이 인버터는 태양광 전력을 역률1인 정현파, 낮은 왜곡율(THDs)로 계통연계 할 수 있는 태양광 인버터 이다. MPPT방식은 전류 센서리스로서 PV모듈의 전압과 MPPT제어 출력 값을 곱하여 PV전력의 정보를 비례적인 값으로 간접적으로 얻는 방식으로 태양광 최대 전력점을 찾을 수 있다. 또한, 계통의 전압으로 위상정보를 얻어 이를 정류시켜 MPPT제어와 곱하여 PWM파형을 발생한다. 제안한 태양광 인버터 전력단 회로는 플라이백으로 불연속 모드(DCM)로 동작하였으며, MPPT제어는 디지털(DSP)로 구현하였다. 100W급 하드웨어로 설계하여 실험을 진행 분석하였다.

전 세계적으로 가장 많은 사용자를 보유한 소셜 네트워크 서비스(SNS)인 페이스북(Facebook)의 이용행태는 사용자의 관점에서 크게 순기능과 역기능적 측면으로 구분된다. 순기능이란 사용자들이 페이스북을 통해 얻는 사회적 지지, 즐거움과 같은 긍정적인 정서로 인해 페이스북을 지속적으로 이용하는 긍정적 측면을 의미하며, 역기능이란 반대로 이용 시 느끼는 피로감, 짜증과 같은 부정적인 정서로 인해 페이스북 이용을 중단하는 부정적인 측면을 뜻한다. 본 연구는 사용자의 개별적 특성이 SNS 이용에 영향을 미친다는 기존 문헌의 결과에 따라, 페이스북 이용자의 특성(인구통계학적 특성, 페이스북 주 활동 특성, 페이스북 이용량 및 이용 빈도 특성)에 따른 페이스북 이용(순기능, 역기능)을 탐색적으로 알아보고자 하였다. 그 결과, (1) 사용자의 인구통계학적 특성 중 여성 사용자가 남성 사용자보다 더 큰 페이스북 피로감과 페이스북 중단의향을 보였으며, 40-50대 사용자가 10대 사용자보다 더 큰 페이스북 피로감을 느꼈다. 또한 (2) 주 활동 특성 중 작성자는 관찰자보다 더 높은 긍정정서와 사회적 지지를 느끼고, 페이스북 지속사용의도 또한 높았다. 마지막으로 (3) 사용자의 이용량 및 이용 빈도 특성 중 일평균 사용시간이 높은 사용자는 낮은 사용자에 비해 긍정정서를 높게 느끼고 지속사용의도 또한 높았다. 반면, 일평균 사용시간이 낮은 사용자는 높은 사용자보다 중단의향이 높은 것으로 나타났다. 사용자 특성별로 이용행태를 분석한 본 연구 결과는 성숙기에 도입한 SNS 시장에 이론적, 실무적 함의를 제공할 것이라 기대한다.

Objectives: Several practice guidelines recommended both medication and behavior modification to control hypertension. The objective of this study was to analyze ambulatory care utilization pattern and related factors. Methods: A retrospective cohort study was conducted among 45,267 new users who initiated treatment with hypertensive drugs in 2003. Korean National Health Insurance Claims Data was used to study the medical care utilization behavior and related factors after treatment initiation for up to four years. Taking prescription was considered as medical care utilization. Results: More than 20% of patients discontinued visiting physicians for prescription after initiating antihypertensive drug therapy. The average number of institutions visited by patients was about 1.3 annually. Clinic was the most frequently visited institution by patients. In GEE analysis, probability of continuous visit one institution after initiating antihypertensive drug treatment increased in patients who were women, old, have comorbidity, visited clinic or hospital mainly in previous year. Conclusions: Young hypertensive male patients who have no major comorbidity showed high possibility to discontinue medical service utilization. It is necessary to educate these targeted patients about importance of hypertension management in early stage after treatment initiation.

Peritoneal dialysis (PD) has been utilized for the children with end stage renal disease. Nevertheless, it is thought to promote inguinal hernia by increasing intraabdominal pressure. To investigate the clinical characteristics of inguinal hernia in children on PD, 155 cases of PD in children between January 1996 and June 2007 at Seoul National University Children's Hospital were reviewed retrospectively. Inguinal hernia developed in 16 cases (10.3 %, M:F=8:8). Hernia occurrence was not correlated to age. Eleven cases (69 %) of inguinal hernia developed in first 6 months after initiation of PD. All inguinal hernias were surgically repaired. No complications occurred related to inguinal hernia or surgery. Recurrent hernia developed in 1 patient (6.3 %) of 2 cases who had PD postoperatively on the day of surgery. In conclusion, inguinal hernia developed more frequently with children on PD than general population (3.5~5 %). The rate of hernia development was highest within the first 6 months following initiation of PD. After repair of hernia, we recommend to discontinue PD immediate postoperatively to prevent recurrence.

Purpose: The purpose of this study was to test a model for intention to discontinuation drinking high caffeinated beverages among undergraduate students. This model was based on the Ajzen's theory of planned behavior and Becker's health belief model. Methods: Participants consisted of 201 undergraduate students. Data were collected by questionnaires from March 11 to May 24, 2019. Collected data were analyzed using SPSS/WIN 22.0, AMOS 22.0 program. Results: The assessment of the model indicated an acceptable fit (normed x²=1.65, goodness-of-fit index [GFI]=.83, adjusted GFI=.79, comparative fit index [CFI]=.92, standardized root mean square residual [SRMR]=.05, Tucker-Lewis index [TLI]=.91, normed fit index [NFI]=.87, root mean square error of approximation [RMSEA]=.07). Perceived behavior control, subjective norm, the subjective attitude was found to have a significant direct effect on the intention to discontinuation of drinking a high caffeinated beverage. The variances of this model explained 45.3% of the variance in intention to discontinuation of drinking a high caffeinated beverage. Conclusion: These results suggest that a need to increase awareness of adverse effects and potential risks of high caffeinated beverage consumption in undergraduate students. Besides, the university and government should provide education and campaigns to prevent excessive high-caffeinated beverage consumption.
