Purpose: The purpose of this study was to investigate the relationships between LLFDI and quality of sleep in older men with prostatic hypertrophic symptoms. Methods: The secondary analysis of data collected for the 2nd stage BK(Brain Korea)21 project was performed. The original data were collected using a cross-sectional, face-to-face, and private interview method. The questionnaires consisted of prostatic hypertrophic symptoms, late-life function and disability, quality of sleep, and demographic profiles. Results: A total of 112 older men included in this study. The major findings of this study were as follow; 1) 29.5% of participants had more than moderate symptoms of prostatic hypertrophy. 2) There were a significant positive correlation of prostatic hypertrophic symptoms with subjective sleep quality, sleep latency, sleep disturbances, use of sleeping medication, and daytime dysfunction found, whereas there was a negative relationship with frequency dimension. 3) The LLFDI is significantly associated with urgency, weak stream, and intermittency. The quality of sleep is significantly associated with weak stream which explained 11.2% of variance. Conclusion: These results may contribute to a better understanding late-life function and disability, quality of sleep in older men with prostatic hypertrophic symptoms. Therefore, health programs for prompting older men's health should be planned based on results of the study.

RSSI기반의 실내위치인식 시스템과 무선센서네트워크를 이용한 자율 이동 로봇의 기능 중에서 선행적으로 요구되는 지능형 실내위치추정 로봇을 설계, 구현하였다. 지능형 실내위치추정 로봇은 주제어장치로서 Spartan III를 사용하였으며, 현재의 위치 데이터는 계속적으로 Zigbee /IEEE802.15.4 무선통신을 사용하여 블라인드노드로 전송된다. 그리고 로봇에 탑재된 베이스스테이션노드는 블라인드 노드를 통해 수신된 위치 데이터를 수집하여 로봇을 제어하였고 서버로 전송하였다. 이동 중인 로봇은 Magnetic Compass를 사용하여 목적지의 방향을 인식하여 최종 목적지로 이동하였다. 또한 프로그램 내에 장애물회피 알고리즘을 이용하여 효율적이고 능동적으로 목적지에 도달하였다. 로봇에 부착된 베이스스테이션노드를 아용하여 서버프로그램에서 환경 데이터와 위치를 실시간으로 모니터링 할 수 있었으며, 서버프로그램에서의 능동적인 로봇제어가 가능하였다.

Potatoes have been recognized for a long time as one of the major food crops as well as horticultural crops. Potato production as a table food has been decreased in developed countries, while it has been steadily increased in the third world countries for it importance as food source. It is a new trend to look for the food, not only as a feeding crop but also healthy food. It is also time for the potato producers to look for the potato having high economic value as found in medicinal plants. There are great diversities in potato species, indicating that valuable compounds can be found in different amounts, depending on potato species. We screened the cultivars, breeding clones, and germplasms based on the vitamin C, Vitamin E, antioxidant compounds, diverse sugar types, important amino acids, and other valuable compounds. We could select the breeding clones KC003, 98Wl17, 99j717, and Vally 8 (A group) due to their high levels of antioxidant compounds, and it can be said that most of the red and purple colored potato clones belong to the A group. In the contents of essential amino acids, ‘Taebook Valley’,‘Summer Valley’ and other breeding clones were found to be high in amount. We also made crosses between breeding clones with high biological function and low agronomic traits and low biological function with high quality in agronomic characteristics . The patterns of genetic trends of these offsprings in comparison with their parents will be reported as well. And the potential of using potato as antibody production of anti-cancer will be discussed.

Background and Objectives: Previous studies have reported an association between impaired renal function and poor outcomes after radiofrequency catheter ablation in patients with atrial fibrillation (AF). However, outcomes of cryoballoon ablation (CBA) in patients with renal insufficiency are not fully elucidated. This study aimed to compare outcomes of CBA in AF patients with chronic kidney disease (CKD) versus those without CKD and to assess changes in renal function over 12 months following CBA. Methods: A total of 839 patients (65.1% with non-paroxysmal AF [PAF]) who underwent de novo CBA were prospectively enrolled. We divided patients into two groups based on creatinine clearance rate (CCr) and performed intracardiac echocardiography (ICE)-guided contrast agent-free CBA. Results: In comparison with patients without CKD (CCr >50, n=722), those with CKD (CCr ≤50, n=117) were older and predominantly female, had a lower body mass index, and showed a higher prevalence of heart failure and hypertension. Mean CHA₂DS₂-VAS score was significantly higher in CKD group than in non-CKD group. Procedure-related complications were not significantly different between two groups. During a mean follow-up period of 25.4±11.9 months, clinical recurrence occurred in 182 patients (21.7%) and not significantly different between two groups. In multivariate analysis, non-PAF and left atrial size were independent predictors of AF recurrence. CCr levels significantly improved over 12 months after CBA in CKD group. Conclusions: ICE-guided contrast-agent-free CBA showed comparable long-term clinical outcomes without increasing procedure-related complications and improvement of renal function over 12 months following CBA in AF patients with CKD.
