  • 비상발전기를 사용하여 무정전 시스템을 구성할 경우, 발전기 시스템이 정전을 인식하고 비상발전기의 기동하는 시간동안은 정전이 발생함으로 통상적으로 단주기 ESS와 결합한 UPS 시스템을 구축하게 된다. 이 경우 UPS 시스템 구축을 위한 ESS 시스템과 인버터에 대한 부담이 존재한다. 본 논문에서는 비상발전기와 엔진의 동력전달 부 사이에 플라이휠과 전자식 클러치에 의한 새로운 비상발전기 단독형 UPS 시스템을 제안한다.

  • 패턴 인식의 성능 향상을 위해 효율적인 특징 선택을 해주는 것은 중요한 과정 중 하나이다. 본 연구에서는 최근에 제시되었던 특징 선택 방법들 중 대표적인 4 가지의 방법을 선택하여 성능을 비교 분석하였다. 데이터의 특징을 줄여주는 기능과 적은 수의 특징으로 더 좋은 패턴 인식 성능을 보여주는 기능의 수행 능력을 중심으로 평가하였으며, 각기 다른 형태의 데이터에 대해 각 방법들이 보이는 성능도 관찰하였다. 이를 토대로 각 방법의 장단점과 특징에 대해 생각해 본다.

  • V. parahaemolyticus possessed an extracellular alkaline protease activity during the stationary growth phase. Various factors such as initial pH of medium, incubation temperature and shaking rate were investigated far optimizing the production of alkaline protease from V. parahaemolyticus ATCC 17802. Maximal activity of the protease was obtained when the bacteria were grown in 2% skim milk medium in 0.1M tris/HCl buffer (pH 7.6). Maximal activity of the protease was obtained when the bacteria were growls at initial pH of 7.6, incubation temperature 37$^{\circ}C$ and shaking rate of 250 rpm.

  • This study was analyzed obesity status by divided into six classification based on the body mass index(BMI) established by World Health Organization-Western Pacific Regional Office(WHO-WPRO) through National Health Insurance Service(NHIS). In the middle of process, problems of outlier solved by presenting the median repeated interpolation. Unlike linear and Lagrange interpolation, median repeated interpolation may be useful in multiple outlier contained dataset. As a result, we found that extreme low and obesity weight gradually increased and the frequency of normal body weight gradually decreased. Especially, the increase of obesity in men and women of lower age group is increasing. Overall, this study suggests that national measures need to be taken before health problems arising from obesity can spread to other social problems.

  • The bleaching phenomenon of otter spraints is indicates that the age of spraints (fresh or old spraints). As previous studies on the old otter faeces (spraint) have focused only on the external changes of spraints, it has been difficult to explain the difference of the decomposition rates among old spraints. We hypothesized that the micrometeorology difference caused by various characteristics of sprainting sites such as porosity and consistency of soil could affect the extent of the decomposition rate, the solar bleaching phenomenon of spraints used as a measure of the patterns of old spraints. Sprainting sites were classified into four types (Clay, Sand, Rock and Concrete spot) and each type was divided into two groups according to the sunlight condition (Sunny site and Shady site) to measure the effect of solar radiation. Micrometeorology of the sites were evaluated by measuring temperatures and humidities of the sites during the whole season. The variations in micrometeorology of the sunny sites according to the sprainting site types were examined with correlation analyses between the factors of micrometeorology. The analyses on the bleaching phenomenon of the spraints by micrometeorology showed that the highest rate of bleaching was found at the 'Rock spot' and 'Concrete spot' of the sunny site and especially in summer, the highest rate of bleaching ($63.4{\pm}7.6%$) was found at the 'Clay spot' of the sunny sites. The lowest rate of bleaching was found at the 'Sand spot' of the sunny sites. The above findings show that the difference in bleaching rates among sprainting sites was due to the seasonal or sunny condition. In addition, we found that the differences in thermal conductivity among sprainting site characteristics have resulted in different sprainting site temperature which have affected the rate of bleaching of spraints. In conclusion, this study suggests that studies of otters on their population size and home ranges using spraints as an indirect sign, should consider the effects of sprainting site characteristics and weather conditions.

  • In this paper, I investigate on the human nature in philosophy of Wang Yang-Ming and Buddhism from a Kantian point of view. The core argument of the philosophy of Wang Yang-Ming, Buddhism and Kant is that all human beings have the pure abilities a priori to overcome themselves, to realize their own potentialities. This is called immanent transcendence. At this time human beings can be free. Kant, Wang Yang-Ming and Buddhism claim that all human beings themselves will overcome their desires from their mind and body through the immanent transcendence, reflection and contemplation on their own. When we give up the external knowledges, throw away obsessions with the selfish desires and go back to our inside, we can see our original nature. To have an insight into this inner nature, to respect the moral law a priori, this is to overcome the ourselves, and to be a Grate Man(聖人) and a Buddha. This way is the only way to be a Grate Man and a Buddha. The main proposition of Wang Yang-Ming's philosophy is expressed 'There are no things without mind.'(心外無物) The core of Kant's transcendental philosophy is called the Copernican Revolution by himself. Copernican Revolution means the transition from the object-centered epistemology to the subject-centered epistemology. 'Innate Knowing'(良知) and 'Perform Innate Knowing'(致良知), 'All human beings have the mind of Buddha'(一切衆生悉有佛性) contain the apriority, immanence of Moral Law. In this respect, the theory of Innate Knowing in Wang Yang-Ming and mind of Buddha in Buddhism, pure Moral Law in Kant has the same structure grounded in subjectivity. Even if we have the mind of Buddha, innate Knowing, moral law a priori, the reason why we don't know our original nature is that we fall into the obsessions with selfish desires, and that we have inclination to external interests. So the moment you see our original nature, ordinary people themselves turn into a Buddha. These changes and transitions are immanent transcendence. All human beings have the ability to do this changes and transitions. Buddha does not exist outside of us, but it exists with our reflections on our human nature. Buddha can not existed without our insight into the our innate Ego. Where there is our original nature, there is a Buddha. So Buddha is called the another name of the original figure of human beings.

  • This study was conducted to investigate the Warner-Bratzler shear force (WBS), sarcomere length, total collagen contents and consumer tests of different cuts of Hanwoo beef based on quality grade. Five cuts [Cheggt (striploin), Dngsim (loin), Moksim (chuck roll), Udoon (top round), Yanggi (brisket)] were obtained from Hanwoo beef (bulls and steers, 24-30 months old) and grouped by their quality grades ($1^{++}$, $1^+$, 1, 2 and 3). The WBS values of chuck cut in $1^{++}$, $1^+$ and 1 quality grade groups were 5.47 (kg/0.5 $inch^2$), 5.46 (kg/0.5 $inch^2$) and 6.54 (kg/0.5 $inch^2$), respectively, which were significantly lower than those of chuck in quality grade 3, which was 8.41 (kg/0.5 $inch^2$) (p<0.05). The sarcomere length of the quality grade groups were significantly longer for brisket (3.72 ${\mu}m$) of $1^{++}$ quality grade than for that of 3 quality grade brisket (p<0.05). Brisket of $1^{++}$ and 2 quality grade had significantly greater sarcomere lengths than strip loin and top round in the same quality grade (p<0.05). The total collagen contents of strip loins in the $1^{++}$, $1^+$, and 1 quality grade groups (1.17, 1.18 and 1.14 g/100 g, respectively) were significantly lower than those of the 3 quality grade group (1.63 g/100 g) (p<0.05). The overall sensory scores of tenderness and juiciness for the five cuts of $1^{++}$ quality grade were significantly higher than those of the other quality grade (p<0.05). Among the five cuts, loin had the highest tenderness and juiciness scores (p<0.05), whereas top round had the lowest tenderness and juiciness scores (p<0.05). Overall, there were significant differences in the WBS and sensory properties among quality grades and cuts (p<0.05). However, the sarcomere length and total collagen contents of chuck roll, top round and loin did not differ among quality grades.

  • We experienced tracheobronchial stenosis caused by malrotation of the heart in a 3-year-old girl. Malrotation of the heart is induced by the decreased right lung volume, which was the result of right lung hypoplasia and herniation of the left thoracic cavity. We corrected the right lung volume and location of the heart to treat tracheobronchial stenosis.
