In this paper, weighted Bloch spaces $\mathcal{B}_q$ are considered on the open unit ball in $\mathbb{C}^n$. In this paper, we will show that every Bloch function in $B_q$ induces a bounded linear functional on $L^1_a(\mathcal{B})$.

As a functionally complicated facility, it requires rational strategy to accommodate multi-functional needs to plan a hospital. Ambulatory surgery units located in large hospitals have problems such as longer waiting time and congestion for patients due to complicated planning and organization within limited area, which raise needs for independent ambulatory surgery centers to enable smoother medical treatment for patients. To design an independent ambulatory surgery center, understanding of zoning and layout of each unit needs is particularly required. This study focuses on research of efficient zoning/organization of day surgery unit and circulation arrangements of ambulatory surgery centers by analyzing various examples abroad, which will eventually help finding appropriate way of planning domestic ambulatory surgery centers. Specific area of research includes ambulatory surgery process, programmatic requirements, spatial organization of the facility, layout of surgery unit and circulation arrangements of ambulatory surgery centers.

The cerebral microvessels possess barrier characteristics which are tightly sealed excluding many toxic substances and protecting neural tissues. The specialized blood-neural barriers as well as the cerebral microvascular barrier are recognized in the retina, inner ear, spinal cord, and cerebrospinal fluid. Microvascular endothelial cells in the brain closely interact with other components such as astrocytes, pericytes, perivascular microglia and neurons to form functional 'neurovascular unit'. Communication between endothelial cells and other surrounding cells enhances the barrier functions, consequently resulting in maintenance and elaboration of proper brain homeostasis. Furthermore, the disruption of the neurovascular unit is closely involved in cerebrovascular disorders. In this review, we focus on the location and function of these various blood-neural barriers, and the importance of the cell-to-cell communication for development and maintenance of the barrier integrity at the neurovascular unit. We also demonstrate the close relation between the alteration of the blood-neural barriers and cerebrovascular disorders.

The purpose of this study is to provide a practical guide for optimum residential and useful architectural condition in a regional area. The data has been collected through survey from exist Housing of a Go-sung Gun Toa-Sung Mun area. Those 21 Housing samples are collected, and are analyzed by standard Architectural codes, country Architectural codes and regulations This study has been processed in analysis of the unit planning and codes condition of each housings, and situation analysis through the practical investing. As a results of this study, the Housing floor plan in rural area should reflect user's needs and functional unit plan. Especially, the unit planning have a good residental environments. An instance, laundry and balcony space. These result will become basic data for the future architectural design in the Housing floor plan in rural area.

The purpose of this study was to develop a production line using simulation method, which could improve work allocation, labor utility and productivity. Using simulation software AIM, a simulation model of functional sports wear assembly line was developed. A functional sports wear production factory were analysed to gather data necessary for this research. Factory layouts, production facilities, work time of each unit jobs were investigated. The data obtained were used as to build a base simulation model. Then, the base simulation model was verified using the obtained data, such as daily productivity. Using simulation method, low alternative production plans were suggested, which were to enhance productivity, and work efficiency and to reduce queue length and throughput time.

This article aims to study the dynamical behaviours of a two species model in which non-selective harvesting of a prey-predator system by using a reasonable catch-rate function instead of usual catch-per-unit-effort hypothesis is used. A system of two ordinary differential equations(ODE's) has been proposed and analyzed with the predator functional response to prey density is considered as Hassell-Varley type functional responses to study the dynamics of the system. Positivity and boundedness of the system are studied. We have discussed the existence of different equilibrium points and stability of the system at these equilibrium points. We also analysed the system undergoes a Hopf-bifurcation around interior equilibrium point for a various parametric values which has very significant ecological impacts in this work. Computer simulation are carried out to validate our analytical findings. The biological implications of analytical and numerical findings are discussed critically.

본 논문에서는 페트리 네트로 記述된 제어 사양을 접속 행렬로 해석한 후, 그 결과를 근거로 병렬 시퀸스의 수행이 가능한 순차 시스템 제어기(Sequential System Controller)를 설계하였다. 순차 시스템 제어기는 입력 처리부, 그리고 점화 처리부와 토큰 제어기로 구성된 페트리 네트 제어기로 구성된다. 입력 처리부에서는 입력 신호를 선택하여 점화 처리부로 전달하며, 점화 처리부는 토큰 운전기의 토큰 상태에 따라서 입력된 신호의 점화 여부를 판단하게 된다. 제안된 제어기는 제어 사양의 변경시 접속 행렬을 저장한 롬의 내용 변경만으로 제어기의 변경이 가능하고, 페트리 네트 제어기의 모듈화가 가능하여 기능의 확장이 용이하므로 자동창고 시스템, 반송 시스템, 및 승강기 시스템과 같은 순차 시스템 제어기의 개발 및 실현을 용이하게 할 수 있다.

A simple oscillating reaction model subject to additive Gaussian white noise is investigated as the model is located in the dynamic region of oscillations. The model is composed of three ordinary differential equations representing the time evolutions of X, Y, and Z, respectively. Initially, a uniform random noise is separately added to the three equations to study the effect of noise on the oscillatory cycle of X, Y, and Z. For a given value of noise intensity, the amplitude of oscillation increases monotonically with time. Furthermore, the noise is added to any one of the three equations to study the impact of noise on one species on the bifurcation behavior of the other.

Objective : The aim of our study was to evaluate the neuroprotective functions of the combination therapy using methylprednisolone (MP) and tranilast (TR) after spinal cord injury (SCI) in adult rats. Methods : Spinal cord compression injury model was achieved using Yasargil aneurysm clip. Rats were divided into control group, MP group, TR group, and combination therapy group using TR and MP. Rat models were assessed for locomotor functional recovery using Basso, Beattie, and Bresnahan (BBB) score, spinal cord water content and myeloperoxidase (MPO) activity 24 hours post SCI, haematoxylin and eosin staining and glial fibrillary acid protein (GFAP) staining at 7 and 14 days post SCI. Results : The spinal cord water content and MPO activity in the combination therapy group was significantly lower than the control group and the individual therapy groups p<0.05. The combination therapy group had significantly higher BBB scores than control group and individual therapy groups (p<0.05). At one week after SCI, GFAP expression in the combination group was significantly lower than the control group (p<0.05) but there was no significant difference compared to the individual therapy groups (p>0.05). At 2 weeks after SCI there was a slight decrease in GFAP expression compared to the first week but the difference was not statistically significant (p>0.05), GFAP expression between the groups was not statistically significant p>0.05. Conclusion : Combining MP and TR is therapeutically more effective in improving functional recovery, inhibiting inflammation and glial scar formation after acute SCI.

This research explored the importance of conflict resolution in communication between adolescents and their parents. A teaching and learning plan on communication using the Active listening, I-message method and no-lose conflict resolution method was developed and applied to teaching the 'Communication among Family Members' unit in the middle school home economics and technology textbook. The experimental class of 203 students using the active listening, I message and no-lose conflict resolution method in communication was compared with a comparative class of 163 students using only the active listening and I message method, investigating the amounts of communication, conflicts, functional communication and degree of satisfaction the students perceived regarding relationships with their parents via pre and post tests. Both groups showed significant increases in their amounts of communication and functional communication. However, only the experimental class showed an increase in their degree of relationship satisfaction with their parents. Both groups evaluated the lesson positively.
