In the center of our ancestor's culture, there were poetry, calligraphy, and painting. Above all, poetry was the heart of the culture involved in everyday life. The beauty of poetry was not limited to appreciation of the poetry but it influenced calligraphy, painting, seals, music, architecture and even how the ancestors viewed their lives. Categories of poetry(詩品, CP hereafter) is the poetry written to deliberate the style of poems and its influence went beyond the fields of calligraphy and painting. Even now, our architecture reflects the sentimental influences and values of CP. In order to understand the attitude, mind, and the world view of the architects in the past, comprehensive and deep understanding of their philosophy as well as their cultural and social norms is needed. In this paper, CP is used as the means to investigate and develop such understanding of our ancestors' philosophy and culture. This paper also intends to investigate how the seclusive thinking of Neo-Confucianism is reflected in CP and the overall literature. In addition, this paper aims to examine the trace of CP in traditional architecture as well as the relationships and the flow among various styles of CP. This study therefore serves as an important base in understanding the ancestor's philosophy that pursued balance between life and art, reason and emotion, study and practice, and their architectural expression. It is also expected that this study would work as the groundwork to regain our traditional culture identity.

Information technology enables home-based working which is a new way to satisfy the firm and its employees. Firms are under pressure of cost reduction, and employees want to maintain balance of life between work and family. Considering the organization's capability can be the core competency, firm's efforts to acquire workers' commitment have been important issue in human resource management. However, researches to increase the workers' loyalty and commitment within home-base working have not been widely studied. This study tries to identify the relationships among firms' rewards supporting strategies and workers' perceived commitment with the working system as a context. Results confirm that the organization's extrinsic and intrinsic rewards affect the worker's continuous commitment, and the mediating role of normative commitment between workers' perceived affective commitment and continuous commitment has been found. Also, we empirically identify the moderating role of working systems(i.e., home-based, vs. office-based) within organization's rewards supporting strategies and workers' commitment perceptions.

In this study, an experimental investigation is performed for evaluation of a liquid pool spreading model with continuous release. The model considered in this study was developed based on a concept which means that the liquid pool spreading is governed by a balance between an inertia force from gravity and a frictional force from friction with the ground under the whole base of the liquid pool. For evaluation of the model, experimental study is performed. Experimental apparatus is setup for measuring release rate, spreading velocity, and evaporation rate from a liquid pool. The experimental results are compared with results from the model. By applying release and evaporation rates obtained from experiments to solving the model, liquid pool radius variation according to time can be obtained. For evaluation of an effect of friction force in the spreading model, results obtained from the models with and without the friction force are compared with those obtained from the experiments. As a result, it is shown that there exists a large deviation between the results obtained from the model without the friction force and the experimental results. On the other hand, the tendency of liquid pool radius variation according to time is similar between the results obtained from the model without the friction force and the experimental results.

In this study, the runoff characteristics of the non-rainfall period were examined using daily rainfall data from 1977 to 2017 and the data of runoff into the dam. Results showed that, the mean runoff decreases with longer non-rainfall periods in the Andong dam basin. The correlation coefficient between non-rainfall days and average runoff reaches 0.85. The results of the analysis of the runoff characteristics during the non-rainfall period, based on the preceding rainfall of Andong dam are as follows. The runoff characteristics of the entire non-rainfall period, shows that, for a rainfall of 1.0 mm or less, the runoff height was larger than the rainfall size and the base runoff larger. The correlation between the antecedent rainfall and runoff height was reached as high as 0.9864 in the 30 ~ 50 mm interval of the antecedent rainfall period, and this is the interval where the linearity of rainfall and runoff was at its maximum in the Andong dam basin. The correlation between the antecedent rainfall and the runoff height reached 0.92 for rainfalls of 100.0 mm. However, for rainfalls of 100.0 mm greater, the correlation between the antecedent rainfall and runoff height during the rainfall period was 0.64, which is relatively small. In this study, we investigated the runoff characteristics of the rainfall period in the Andong dam watershed. As a result, it was confirmed that the mean runoff decreased with rainfall duration. The linearity was found to be weak for rainfall events greater than 100.0 mm. The results of this study can be used as data for water balance analysis and for formulating a water supply plan to establish water resource management of Andong dam.

Purpose : The purpose of this study is to report the effect of oriental treatments to hyperemesis gravidarum in disturbed liver function. Methods : Hyperemesis gravidarum is a severe and intractable form of nausea and vomiting in pregnancy. It is a diagnosis of exclusion and may result in weight loss; nutritional deficiencies; and abnormalities in fluids, electrolyte levels, and acid-base balance. The peak incidence is at 4, 8-16 weeks of pregnancy. Interestingly, nausea and vomiting of pregnancy is generally associated with a lower rate of miscarriage. However disturbed diver dunction with Hyperemesis gravidarium is rare very and dangerous. Traditionally, oriental medical therapy has been used to patients with hyperemesis gravidarum and showed effective result. We treated 1 patient who had hyperemesis gravidarum in disturbed diver dunction at Se-Myung university Oriental Hospital in affiliation by Herbal medication, acupuncture and moxa therapy and got good result from them. Results : As a result, symptoms are remarkably alleviated and liver function test are improved. Conclusion : Therefore we would like to report that it is effective to cure the hyperemesis gravidarum in disturbed liver function through the herb-medication and acupuncture treatment.

One of the most important factors on the performance of the distributed systems is the effective distribution of the software components, There have been a lot of researches on partitioning and allocating the task-based system, while the studies on the allocating the objects of the object-oriented system into the distributed object environments are very little relatively. In this paper. we defines the graph model for partitioning the existing C++ application and allocating the C++ objects into CORBA-base distributed system, In addition, we propose a distributed object allocation algorithm based on this graph model. The performance of distributed systems is determined by the concurrency between objects, the load balance among the processors and the communication cost on the networks. To search for the solutions optimizing the above three factors simultaneously, the object allocation algorithm of this paper is based on the Niched Pareto Genetic Algorithm (NPGA). We performed the experiment on the typical C++ application and CORBA system to prove the effectiveness of our graph model and our object allocation algorithm.

The delicate histological structure of gill in teleosts can be easily affected by a variety of biological, chemical or physical detrimental agents because it is directly exposed to the surrounding water. The epithelium of secondary lamella is thin to allow efficient gaseous exchange and this also renders it particularly vulnerable to various pathogens. As well as the main respiratory role, the gill has other various important functions such as acid-base balance, osmoregulation or the excretion of nitrogenous waste products. Thus destruction of epithelial integrity such as epithelial necrosis or thickening can render a fish very vulnerable to respiratory, secretory and excretory difficulties. This article was tried to describe in detail the common processes of pathological responses correlated to the normal histological structures of the gill in teleosts.

PEGASIS, a chain-based protocol, forms chains from sensor nodes so that each node transmits and receives from a neighbor. In this way, only one node (known as a HEAD) is selected from that chain to transmit to the sink. Although PEGASIS is able to balance the workload among all of the nodes by selecting the HEAD node in turn, a considerable amount of energy may be wasted when nodes which are far away from sink node act as the HEAD. In this study, DERP (Distance-based Energy-efficient Routing Protocol) is proposed to address this problem. DERP is a chain-based protocol that improves the greedy-algorithm in PEGASIS by taking into account the distance from the HEAD to the sink node. The main idea of DERP is to adopt a pre-HEAD (P-HD) to distribute the energy load evenly among sensor nodes. In addition, to scale DERP to a large network, it can be extended to a multi-hop clustering protocol by selecting a "relay node" according to the distance between the P-HD and SINK. Analysis and simulation studies of DERP show that it consumes up to 80% less energy, and has less of a transmission delay compared to PEGASIS.

Mobile Ad hoc Network(MANET) consists of a node that has mobility. In MANET, the node has routing, the node builds a network of their own, no dependent infrastructure. Topology are exchanged due to node mobility in MANET. For reducing the change of topology, hierarchical network algorithm has been investigated. In hierarchical network, cluster member node communicates through cluster head node. When the load-balancing of cluster head node is exceed, assigned cluster member node can't communicate with base station. To solve this problem, we proposed Load Tolerance algorithm. The proposed algorithm, when cluster member node can't send a message by cluster head node that exceed load-balancing, then the cluster member node sends a message by selected load tolerance node. Through a simulation, the proposed algorithm improves packet delivery ratio in cluster routing.
