This study was conducted to find how to manage the household financial situation and what households demand to financial organization for their satisfaction in Chungbuk Province. The questionnaire survey was implemented from 24th of Oct. for two months and 330 households data among 350 households were analyzed and selected as a sample. The results were as follows : 1. Many households had four to six bankbooks and wives visited financial organs more frequently than their husbands. 2. Although many respondents regarded the safety as the most important point when they selected the financial organ, they were choosing the organ because of the nearness form their own house. 3. How to manage the households' financial situations and how much they were satisfied with the financial organs were different by the respondents' age and education level. 4. The younger they were and the higher the education level was, they managed the household according to the financial plan. Female consumers were more satisfied with financial organs than male did. 5. The financial problem were solved through the couple's communication in many households. This study showed the tendency that the wives' power increasing in the households's decision-making about financial problems.

In this paper a detailed description of collecting Korean audio-video speech data is presented. The main aim of this experiment is to collect some audio-video materials which can be used for later experiments to estimate and model the actions of the visible human articulatory organs such as mouth, lips and jaw. We collect audio-video data from seven directions separately. Twelve markers are used to trace the movements.

This paper analysed the induced current density inside human body of hot-line worker for 765kV double circuit transmission line according to locations of human body Human was modelled by several organs, which included brain, heart, lungs, liver and intestines. We applied the 3 dimensional boundary element method to calculate induced electric fields.

Xenotransplantation is a hot topic currently, since the demand for diverse organs is increasing in patients. Among many species, pigs are suitable animals for xenotranplantation as they share many anatomical and physiological characteristics with humans. This review article provides an overview of porcine xenotransplantation and the rejection of pig xenotransplants in primates, and use of genetically modified and cloned pigs in xenotransplantation. It also highlights major target organs in porcine xenotransplantation and virus infection in xenotransplantation.

Development of a locomotive mechanism fer the capsule type endoscopes will largely enhance the ability to diagnose disease of digestive organs. In connection with it, most of researches have focused on an installable locomotive mechanism in the capsule. In this paper, it is introduced that the movement of a capsule type endoscope in digestive organ can be manipulated by magnetic force produced outside human body. Since the magnetic force is provided by permanent magnets, no additional power supply to the capsule is required. Using a robotic manipulator for locating the external magnet, the capsule motion control system can cover the whole human digestive organs. This study is particularly concentrated on dither motion effect to improve the mobility of capsule type endoscope. It was experimentally found out that the friction coefficient between the capsule and digestive organ can be remarkably reduced by superposing yawing or rolling dither motion on the translatory motion. In this paper, the experimental results obtained with the direction, amplitude and frequency of sinusoidal dither motion changed is reported.

Development of a locomotive mechanism for the capsule type endoscopes will largely enhance their ability to diagnose disease of digestive organs. As a part of it, there should be provided a detection device of their position in human organs for the purpose of observation and motion control. In this paper, a permanent magnet outside human body was employed to project magnetic field on a capsule type endoscope, while its position dependent flux density was measured by three hall-effect sensors which were orthogonally installed inside the capsule. In order to detect the 2-D position data of the capsule with three hall-effect sensors including the roll, pitch and yaw angle, the permanent magnet was extra translated during the measurement. In this way, the 2-D coordinates and three rotation angles of a capsule endoscope on the same motion plane with the permanent magnet could be detected. The working principle and performance test results of the capsule position detection device were introduced in this paper showing that they could be also applied to 6-DOF position detection.

Human bone marrow-derived mesenchymal stem cells (MSCs) are a rare population of undifferentiated cells that have the capacity of self renewal and the ability to differentiate into mesodermal phenotypes, including osteocytes, chondrocytes, and adipocytes in vitro. Recently, MSCs have been shown to reside within the connective tissue of most organs, and their surface phenotype has been well analyzed. Many reports showed that transplanted MSCs enhanced regeneration as well as functional improvement of damaged organs and tissues. The wide differentiation plasticity of MSCs was expected to contribute to their demonstrated efficacy in a wide variety of experimental animal models and in human clinical trials. However, new findings suggest that the ability of MSCs to alter the tissue microenvironment via secretion of soluble factors may contribute more significantly than their capacity for differentiation in tissue repair. This review describes what is known about the cellular characteristics and differentiation potential of MSCs, which represent a promising stem cell population for further applications in regenerative medicine.

Background: Vitamin C is an essential nutrient for maintaining human life. Vitamin C insufficiency in the plasma is closely related with the development of scurvy. However, in vivo kinetics of vitamin C regarding its storage and consumption is still largely unknown. Methods: We used $Gulo^{-/-}$ mice, which cannot synthesize vitamin C like human. Vitamin C level in plasma and organs from $Gulo^{-/-}$ mice was examined, and it compared with the level of wild-type mice during 5 weeks. Results: The significant weight loss of $Gulo^{-/-}$ mice was shown at 3 weeks after vitamin C withdrawal. However, there was no differences between wild-type and vitamin C-supplemented $Gulo^{-/-}$ mice (3.3 g/L in drinking water). The concentration of vitamin C in plasma and organs was significantly decreased at 1 week after vitamin C withdrawal. Vitamin C is preferentially deposited in adrenal gland, lymph node, lung, and brain. There were no significant changes in the numbers and CD4/CD8 ratio of splenocytes in $Gulo^{-/-}$ mice with vitamin C withdrawal for 4 weeks. And the architecture of spleen in $Gulo^{-/-}$ mice was disrupted at 5 weeks after vitamin C withdrawal. Conclusion: The vitamin C level of $Gulo^{-/-}$ mice was considerably decreased from 1 week after vitamin C withdrawal. Vitamin C is preferentially stored in some organs such as brain, adrenal gland and lung.

Allopathic medicine has had a lot of limits though it has maintained the status of mainstream medicine, therefore these days there has been a growing interests in traditional medicine of East Asia. According to this trend, the integration between allopathic medicine and traditional medicine has become a hot issue and the need of mutual understanding on their physiology and pathology increases. However, understanding of traditional medical theory based on ying-yang, five phases, viscera and bowels is still difficult to be accepted to allopathic medical fields. Therefore, this research tried to investigate the similarity and differences of the structures between five viscera and organs. As a result, this research found that the investigation and understanding on viscera in traditional medicine or organs in allopathic medicine has in common in some degree. However, the integration and comparison between two medicines should be done cautiously because there still are the basal different points of understanding of human structure and function.
