  • This study is to identify the present condition and level of human resource administration in domestic profit and non-profit organizations, and to investigate on the relation between human resource management and management performance in enterprise. This study is to make items related to the human resource management of American Malcolm Baldrige Award's level and management performance researching questions, investigates seven patterns of organs surveyed positively. The results are as follows: Firstly, the profit organs like manufacturing companies shows more positive than non-profit in comparison with human resource management of each organs. And a local government and public enterprise which is non-profit show to recognize human resource management is insufficient on th whole. Secondly, perception level of a medical institution, educational institution and service industry about aromaticity of human resource management by global standard shows to be positive, but the local government negative. Thirdly, the profit organ in the recognition of human resource management about details practice too, shows to be positive, while non-profit negative. Fourth, the result which compares and analyzes management performance between the similar industry overall show to recognize positive, but public enterprise negative about product, service performance and human resource management. Fifthly, the details practice of human resource administration shows to influence meaningly to all management performance. Therefore, all organizations will positively confront human resource management, make the circumstance of organization through systematic program, and promote the management performance of the organization.

  • This paper analysed the characteristics of current density induced inside human body by 60 Hz extremely low frequency magnetic fields according to varying conductivities of human model. Human model was composed of several organs and other parts, whose shapes were expressed by spheroids or cylinders. Organs such as the brain, heart, lungs, liver and intestines were taken into account. Applying the boundary element method to the human model, we estimated effects on the induced current distribution due to differences of the organ conductivity and shape. We find organ conductivity influences most and a cross section area and a position of organ also gives effects.

  • The change in the position of the abdominal organs due to movement by respiration is one of the reasons behind inaccurate irradiation of organs during radiotherapy (RT). Although studies in human medicine have revealed on the respiratory movements of abdominal organs, there is little information and no reference data for dogs. The purpose of this study was to establish the reference values of abdominal organs movement in various postures using computed tomography (CT), and to compare the movements of organs between dorsal recumbency and ventral, right and left lateral recumbency during respiration. CT images for kidney, adrenal gland, medial iliac lymph node, urinary bladder, gallbladder, liver, stomach, and thoracic and lumbar vertebral body of five beagle dogs were acquired. The movements of organs were evaluated by comparing the end-expiratory and end-inspiratory images. Movements of the organs were evaluated by dividing it into right-to-left, dorsal-to-ventral, and cranial-to-caudal directions. The movements of abdominal organs according to the change in postures and respiration were establish. The movement of the bilateral organs was the least when the organs were in the downward position (p < 0.017). The movement of cranial-to-caudal direction was greater than the movement of the other directions in most of the organs. Data obtained in this study may be useful in selecting the appropriate posture that can reduce the movements of organs to be treated with RT, and the data could be useful for setting the planning target volume to consider the movements of the abdominal organs by respiration.

  • "Jinaik(津液)" is essential nutritious body fluid for human to be alive, and it can be divided various kinds according to it's location, character, and function. Five Fluids -sweat, snivel(mucus), slobber(saliva), tear, spittle(saliva)- are kinds of "Jinaik(津液)", and all of them belong to kidney. They are also related with five organs, such as sweat belongs to heart, snivel(mucus) belongs to lung, slobber(saliva) belongs to spleen, tear belongs to liver, spittle(saliva) belongs to kidney. We can find out five organs' physiological and pathological conditions by means of observations on the Five Fluids. Five organs' function comes out upper seven openings -two eyes two ears, nose, mouth and tongue. The Five Fluids provide all the nutrition upper seven openings need, so they can help for human to hear, see, smell, and taste properly.

  • Introduction: The crucial step in preclinical process of radiopharmaceutical production is internal dosimetry evaluation by different ways to realize radiobiological dose-response relationships and to extract the results for clinical use. Till now several bone-seeking radiopharmaceuticals have been developed for bone metastasis. Interesting features of bisphosphonates attracted attentions to them in the field of radiopharmaceutical therapy and studies on new generation of them have been doing too. Materials and methods: In this study, we used ZNA as representative of the third generation. The radiopharmaceutical 188Re-ZNA was produced and its radiochemical purity was investigated. Then, the biological distribution of the produced radiopharmaceutical at 1, 2, 4 and 24 h after injection on different organs of mice were investigated. Finally, the absorbed dose of organs in the human body was assessed using the RADAR method. Results: The results show 96% radiochemical purity of the 188Re-ZNA radiopharmaceutical. The amount of %ID/g in bone is 1.131% after 1 h and in 24 h it has a significant amount compared to other organs, that is 0.516%. Also dosimetric results show that the highest absorption dose is related to bone and the amount of this dose is 0.050 mGy/MBq. Conclusion: Considering the possibility of producing the 188Re-ZNA radiopharmaceutical, as well as the proper distribution of this radiopharmaceutical in target and non-target organs and increasing the absorbed dose in bone, it can be concluded that this radiopharmaceutical can be useful in the "radiopharmaceutical therapy" in metastases.

  • The cough is generally known as a symptom occurred from Lung. But it was descriptive of the symptom every internal organs can cause in "HwangjenaegyeongSomun Haelon". The reason is that, when a pathogenic Gi attack human body, the body skin which have the relationship to Lung is attacked firstly. But the internal organs preside over each seasons of the year, so the season's presiding organ is ultimately attacked. And in "Somun Haelon" the partner symptoms of five solid organs cough and six hollow organs cough are being described, so we can distinguish between each internal organs coughs. Clinically, the cough is most common symptom and one of the most difficult symptom. In my opinion, the origin organ of cough is very various, but the doctor fix their thinking to the Lung, so the cough became a most difficult symptom. This thesis describe pathogenesis and partner symptoms of five solid organs cough and six hollow organs cough. And illustrate clinical examples and some medical prescriptions. Intend to show that various treatment after differentiation of syndromes[辨證施治] surely needed for effective curing of a cough.

  • Human health is affected by not only physical conditions but also mental and social well-being. Changes of human emotions show up as gestures, facial expressions and sweating. Human emotions are affected by such automatic nerve system functions as blood pressure, blood circulation speed, heart beats, pupillary reflex, fluid transfusion, muscular contraction and digestive organs, all of which influence the holistic diseases. The Oriental Medicine sees from a perspective of unity of divinity and men that human life activities are united in terms of their physical and mental functions. From such a perspective, human Five Organs are linked with Five Mental(五神) and Seven Emotions(七情), while they are affected by each other, influencing the life activities both directly and indirectly. Based on Confucianism, Sa-Sang Theory argues that human emotions can be categorized into four energy states and therefore, that human diseases and physiological conditions there of may be determined differently depending on the Four Energies(四氣). There seems to be some common points between Sa-Sang Theory and the conventional Oriental Medicine in that human emotions affect individuals' health conditions, so there seems to be much room for mutual complementation.
