We analyzed transient Ca II brightening associated with small-scale canceling magnetic features in the quiet Sun near disk center using Ca II H and NaD1 filter images of the SOT/Hinode. We found that in most Ca II brightening related to CMFs the Ca II intensity peaks after magnetic flux cancellation proceeds. Moreover, brightening tend to appear as pairs of bright points of similar size and similar brightness overlying magnetic bipoles. These results imply that magnetic reconnection taking place in the chromosphere or above may be in charge of CMFs.

Rainwater harvesting systems (RWHS), one of measures for on site rainwater management, have been promoted by laws, regulations and guidelines and have been increased. However, more evaluation of economic feasibility on RWHS is still needed due to seasonal imbalance of rainfall and little experiences and analysis on design and operation of RWHS. In this study, we investigated tank capacity of RWHS to secure economic validity considering catchment area and water demand, which is affected by building scale. Moreover, sensitivity analysis was performed to examine the effect of design factors, cost items and increase rate of water service charge on economic feasibility. The BCR (benefit cost ratio) is proportional to the increase in tank capacity. It is increased steeply in small tank capacity due to the effect of cost and, since then, gently in middle and large tank capacity. In case of 0.05 in the rate of tank volume to catchment area and 0.005 in water demand to catchment area, BCR was over one from the tank capacity of 160 $m^{3}$ taking into account of private benefits and from the tank capacity of 100 $m^{3}$ taking into account of private and public benefits. Sensitivity analysis shows that increase of water demand can improve BCR values with little cost so that it is needed to extend application of rainwater use and select a proper range of design factor. Decrease of construction and maintenance cost reduced the tank volume to secure economic validity. Finally, increase rate of water service charge had considerable impact on economic feasibility.

Purpose. The purpose of this study was to explore the experiences of gastric cancer couples in Korea and to generate a substantive theory integrating the experiences of gastric cancer survivors and their spouses as a whole. The specific aims of this study were to explore major problems gastric cancer couples faced and how they resolved these problems, focusing on inter-relational dynamics within the couples and on similarities and differences between the couples. Methods. This was a secondary analysis study using grounded theory techniques. The study used the data of 11 married couples which was collected from in-depth interviews from two primary studies. The unit of analysis was dyads of gastric cancer survivors and their spouses. Results. The basic social psychological process that emerged from the analysis was 'taking charge of their health.' Major categories involved in this process were identified as 1) adjusting to new diets, 2) reinforcing physical strength, 3) seeking information, 4) strengthening Ki, 5) lowering life-expectations, and 6) going their separate ways. These six categories represent major strategies in overcoming critical problems that occurred in day-to-day experiences. In terms of the process, the first five categories characterize the earlier stage of the process of 'taking charge of their health,' while 'going their separate ways' indicates the later stage and also the beginning of their separate ways: 'pursuing spiritual life' for the survivors, and 'preparing for the future' for the spouses. Conclusions. The results of this study will help design family care for the people with gastric cancer by providing in-depth understanding and insight on the lives of gastric cancer couples.

Today, importance is being placed on interior design and thus the scope of interior design market became very large. Management environment of an interior design office, however, often faces manu difficulties to meet a variety of customers' demand, so that expert and reasonable management ability is required. Accordingly, this study was conducted to provide basic materials on management environment for maximizing profit generation of an interior design office by investing real management situation on the subject of persons participating in management of an interior design office. As a result of investigation of 80 interior design offices which was registered in Daegu, design ratio of most of the offices was found to be less than 20% due to building owners' lack of recognition of and insufficient legal systems, and in spite that there was a department or staff fully in charge, top management makes an estimate. With regard to importance of interior design, it was found that they regarded reliability with customers as most important, and give priority to practical ability and human nature in employing a new comer. It was revealed that most offices have neither department taking fully charge of marketing, nor positive publicity, and in outside activities, the major of management have high relation with sales.

The purposes of this study which was conducted by studying the literature on Emergency Medical Dispatch System are to provide some developmental policies of quality management, pre-arrival instructions, priority dispatch protocols, training program for the dispatchers(Emergency Medical Dispatchers or EMDs) in Korea and to promote understanding emergency medical dispatching. The conclusions from this summarized as follows; (1) It is confirmed that there has been little study on the Emergency Medical Dispatch System in Korea, because for the first time, the real Emergency Medical Services were introduced into Korea in 1994, and the importance of the Emergency Medical Dispatch System has not been realized. (2) Only some squads are using a set of dispatch protocols, others aren't. (3) In spite of trying to introduce a new set of dispatch protocols, it isn't the priority dispatch system using a complete set of dispatch protocols which has key questions, pre-arrival instructions, mode & configuration based on patient assessment. (4) The EMS is unable to promote the service capacity by using quality management, because there is no medical control on the emergency medical dispatching and the EMDs. (5) There are no medical directors in the communications center who are in charge of the medical control to detect problems derived from the EMS and to solve them. (6) There are no systematic training program for the EMDs who are taking charge of dispatching. (7) Having a deep relation to the elements of the EMS, the emergency medical dispatching is subject to restriction of those elements.

반도체 제조공정 중 플라즈마 반응기 내에서 입자오염을 유발하는 입자들의 거동과 성장을 모델식을 사용하여 이론적으로 고찰하였다. 플라즈마 반응기 내에서 입자 거동에 영향을 미치는 힘들로 유체 대류, 입자 확산 및 외부힘 (ion drag force, electrostatic force, 중력) 등을 고려하였다. 플라즈마 벌크 영역에서 전하를 가진 입자들간의 충돌에 의한 입자 성장을 고려하기 위해 모델식에 입자 전하 분포를 고려하였다. 대부분의 입자들은 ion drag force와 electrostatic force가 균형을 이루고 있는 두 sheath 경계 영역에 존재하였으며 두 sheath 영역과 벌크 플라즈마에서의 입자 농도는 0에 접근하였다. 시간이 지남에 따라 입자 충돌로 인한 입자들의 크기는 증가하였으며 입자가 성장함에 따라 입자 표면적의 증가와 더불어 입자가 가지는 평균 전하량도 증가하였다.

Among various fuel cells, solid oxide fuel cells (SOFCs) offer the highest energy efficiency, when taking into account the thermal recycling of waste heat at high temperature. However, the highest efficiency and lowest pollution for a SOFC can be achieved through the sophisticated control of its constituent components such as electrodes, electrolytes, interconnects and sealing materials. The electrochemical conversion efficiency of a SOFC is particularly dependent upon the performance of its electrode materials. The electrode materials should meet highly stringent requirements to optimize cell performance. In particular, both mass and charge transport should easily occur simultaneously through the electrode structure. Matter transport or charge transport is critically related to the configuration and spatial disposition of the three constituent phases of a composite electrode, which are the ionic conducting phase, electronic conducting phase, and the pores. The current work places special emphasis on the quantification of this complex microstructure of composite electrodes. Digitized images are exploited in order to obtain the quantitative microstructural information, i.e., the size distributions and interconnectivities of each constituent component. This work reports regarding zirconia-based composite electrodes.
