현재 운용되고 있는 직접부하제어 알고리즘은 직접부하제어 사업에 참여에 따른 수용가의 개별 부하별 우선순위가 고려되지 않고 있고, 또한 제어 시간도 수용가의 불편을 고려되지 않고 획일적으로 일정 시간대에 일률적으로 수용가의 부하를 제어함으로써 참여 수용가의 불편 증대로 참여율이 저조한 실정이다. 따라서 본 연구에서는 참여 수용가의 불편을 최소화시키고 또한 개별 부하에 대한 우선순위 요구를 최대한으로 반영하기 위해 우선순위 기반 동적 프로그래밍을 이용한 직접부하제어 알고리즘을 제시한다. 제시되는 알고리즘은 직접부하제어가 발생되기 1시간 전에 참여 수용가가 스스로 해당 부하의 우선순위를 결정하여 직접부하제어 센터로 I-Mail 등으로 보네면 센터에서는 현재 부하의 전력량과 우선순위 그리고 OFF주기 등을 고려하여 동적 프로그래밍을 수행하여 OFF되어야 할 부하들을 선택하게 된다. Currently used DLC(Direct Load Control) algorithm is only focused on ON/OFF load control not concerning about reliving participated customer's inconvenience and load priority. Therefore, that is a major obstacle to attract customer participating in demand response program. To overcome the above defects, the authors represent direct load control algorithm using priority based dynamic programming. the proposed algorithm is that participant customer send E-mail to DLC center about priority of load before executing DLC, then DLC algorithm decide which load to be OFF by using priority and off time constraint of the load. By using dynamic programming based on the order of priority for DLC algorithm it is possible to maximize participating customer's satisfaction and it will help to attract more customer's participating in demand response program.

Type 1 neurofibromatosis (NF1), also known as von Recklinghausen’s disease, is a common autosomal dominant neurocutaneous disorder. Persons with NF1 have an increased risk of malignancy compared with the general population, but there are few reports of neurofibromatosis combined with breast cancer. We report on three cases of breast cancer combined with NF1.

Purpose: The purpose of this study is to identify the epidemiologic and clinical characteristics of respiratory adenovirus infections in children, and to investigate the difference in the clinical features between single adenovirus infection and coinfection with adenovirus and other respiratory viruses. Methods: A retrospective study was performed in 470 children hospitalized with respiratory adenovirus infections in Gwangmyeong Sungae Hospital between January 2013 and December 2013. Results: The mean age of the patients was 46.2 months and the peak incidence was in the 12- to 24-month age group. The mean duration of hospitalization and fever were 4.5±1.1 and 4.5±9.2 days, respectively. Seasonally it had occurred throughout the year, but showed the highest prevalence in August and high prevalence in July, September, and October. The frequency of viral coinfection with other respiratory viruses was 39.6%. The age was significantly younger in coinfection group than in the single adenovirus infection group (P<0.001). The prevalence rates of bronchiolitis (P<0.001) and pneumonia (P=0.042) were significantly higher in the respiratory syncytial virus coinfection group. The coinfection rate was significantly higher in children aged less than 2 years (P<0.001), and the prevalence rates of bronchiolitis (P<0.001) and pneumonia (P<0.001) were also higher in the group aged less than 2 years than other age groups. Conclusion: Adenovirus is an important viral agent in hospitalized children with acute respiratory tract infection. Lower respiratory tract infections, such as bronchiolitis and pneumonia, and coinfection with other respiratory viruses were more frequently occurred in patients under 2 years of age. Further studies are needed to clarify whether coinfection with other respiratory viruses would increase the rate of lower respiratory tract infections in patients with respiratory adenoviral infections.

급성 췌장염은 임상의들이 흔히 진료할 수 있는 질환으로 임상적으로 경증에서 중증까지 다양하고, 중증의 경우에는 다발성 장기부전 및 사망에 이를 수 있는 치명적인 질환이다. 외국에서는 이 질환에 대한 가이드라인이 개발되어 사용되고 있지만, 국내에 적합한 급성 췌장염의 진단과 치료에 관한 가이드라인 없는 실정이다. 이에 대한췌담도학회에서는 급성 췌장염의 진료와 국민보건향상에 도움이 될 수 있는 가이드라인을 개발하였다. 가이드라인은 4분야 39개의 항목으로 구성되어 있다. 즉 4 분야는 급성췌장염의 진단(11개), 중증도 평가(6개), 초기치료(9개), 국소 합병증 및 괴사성 췌장염의 치료(13개)로 구성되었다. 본 고에서는 이 가이드라인의 소개에 앞서 가이드라인의 개발 목적과 과정 등을 소개하였다. Acute pancreatitis is a common and potentially lethal disease that is associated with significant morbidity and consumes enormous health care resources. There was still no the current domestic standard guidelines for acute pancreatitis. To provide a framework for clinicians to manage acute pancreatitis and to improve national health care, guidelines have been developed by the Korean Pancreatobiliary Association. These guidelines consisted of 39 consensus statements for the diagnosis (n=11), the assessment of the severity (n=6), initial management (n=9), the treatment of necrotizing pancreatitis and local complication (n=13) of acute pancreatitis were developed. In this article, we will describe the purpose and process of the formation of the guidelines.

This study attempted to investigate how mass media marketing of a hospital influences patient volume. Additionally, the association of patient volume with exposure time and the type of mass media was examined. Data from a university hospital in Bundang (from January 2014 to November 2014) were used. Degree of physicians` mass media marketing was measured by the number of media exposure. Linear mixed model for repeated measures data was run to identify the associations between the number of media exposure and patient volume. First, the number of hospital physician`s mass media exposure and new patients and the first visit patients were positively associated. Second, broadcasting media which has relatively significant in patient volume is TV programs such as cultural programs and news. Third, hospital physicians with higher ranks who were exposed to press media receive more patient appointment. Also, nonsurgical hospital physicians who were exposed to press media receive more patients. Fourth, medical treatment activities for hospital staff who hold the rank of Professor in case of making an appearance at press media have relatively increased. Hospital physician`s media exposure, particularly TV programs, was significantly related to patient volume for outpatients.

Purpose: Oncoplastic surgery (OPS) has emerged as the latest ideal surgery in treatment of breast cancer. The purpose of this study is to evaluate the cosmetic outcome of volume displacement surgery and patients’ satisfaction in Korean women with relatively small breast size. Methods: This is a retrospective study of 173 patients who had volume displacement of OPS between January 2008 and December 2013. Cosmetic outcome was evaluated by patients’ questionnaire and a doctor. The patients’ satisfaction was assessed by a questionnaire divided into four categories; cosmetic satisfaction, satisfaction on operative method, femininity, and side effects. Relationship between removed specimen volume and patients’ satisfaction was also analyzed. Results: About 90% of patients answered above the fair in cosmetic items and operative methods, only less than 5% of all patients reported of severe complications such as cramps or limitations of exercise. The patients’ cosmetic satisfaction score were significantly inversely related with removed specimen volume and doctor’s cosmetic assessment was also accordance with this result (P<0.05). Most patients preferred good contour over short scar regardless of age and marital status (good contour 54% vs. short scar 21%). Conclusion: Volume displacement of OPS brings both the best possible cosmetic outcome and high patient satisfaction for Korean women with a small size of breast in breast cancer surgery. It is highly suggestive that Korean women considers good contour more than the size of scar; therefore, volume displacement of OPS is a recommendable means of breast cancer surgery for Korean women.
