  • Three species of tapeworms infect humans in their adult stage (Taenia solium, Taenia saginata and Taenia asiatica). The 3 are flat, opaque white or yellowish, and exceptional long segmented parasites, measuring 1 to 12 m in their adult stage. In this review, the development of the knowledge regarding the first species, mainly focused on understanding how the larval stage or cysticercus is transmitted to humans, is described. The second species is a cosmopolitan parasite that only causes taeniosis and not cysticercosis; therefore, it will not be included. Information on the third species, which is presently being produced, since this species was recognized as such only at the end of the 20th century, will be discussed at the end of this review.

  • Lung transplantation is the only treatment option for patients with end-stage lung disease. Although more than 4,000 lung transplants are performed every year worldwide, the standardized protocols contain no guidelines for monitoring during lung transplantation. Specific anesthetic concerns are associated with lung transplantation, especially during critical periods, including anesthesia induction, the initiation of positive pressure ventilation, the establishment and maintenance of one-lung ventilation, pulmonary artery clamping, pulmonary artery unclamping, and reperfusion of the transplanted lung. Anesthetic management according to the special risks associated with a patient's existing lung disease and surgical stage is the most important factor. Successful anesthesia in lung transplantation can improve hemodynamic stability, oxygenation, ventilation, and outcomes. Therefore, anesthesiologists must have expertise in transesophageal echocardiography, extracorporeal life support, and cardiopulmonary anesthesia and understand the pathophysiology of end-stage lung disease and the drugs administered. In addition, communication among anesthesiologists, surgeons, and perfusionists during surgery is important to achieve optimal patient results.

  • Ultrastructural changes in the cuticle of Paleamon serrifer associated with the intermolt cycle were examined and quantified as changes in the cuticular thickness. The cuticular thickness in each zoea stage increased with time elapsed after molting. The cuticle in the premolt stage was about 1.5 and 3 times thicker than that in the postmolt and intermolt stage, respectively. The cuticle in the premolt stage, including the molting space, was more than 5 times as thick as in the postmolt stage. In addition, newly hatched larvae were individually reared in the laboratory and body length for each specimen was measured frequently until the end of zoea VI. An average increase in body length between one zoea stage and the next is about $10\%$ of the length of the previous stage. Within individual zoea stages, the premolt stage had a body length some 0.3% longer than that of the postmolt stage, indicating a growth rate of about 0.03 mm/d.

  • Durlng various experiments and investigations with antigrowth virus, I studied especially the infective and antiinfective process of it in small animals, and have got following results: 1. The rabbits are easily infected with this virus, having following five stages; incubation period of 2 to 3 days, stage of fever for 2 to 4 day, transient anemic stage, transient fcteric stage and stage of lasting iron-precipitation in the spleen. 2. According to the appearance of icteruis, I have divided the rabbits into following three groups, the first gorup, weighting less than 1000g, died after appearance of icterus, the second group, weighting 1000 to 1500 g. recoy ered after appearance of icterus, and the third group, weighting more than 1500 g. recovered without the appearance of jaundice. 3. In hematological study, marked decrease in R. B. C. and Hb were recognized but various leucocytes except lymphocytes slightly increased. 4. In pathological study, the spleen exhibited marked swelling with abundent blood and indistinct border between trabeculae and pulps at the initial stage of icterus and notable atrophy at the end stage of it. There are few iron-cells in the spleen histologically at the initial stage, but they increased in number with granuar appearance at the end stage. In the first group of rabbits above mentionel, the iron-cells increase suddenly with the death of animal and show diffuse precipitation of iron. The liver and indey have defferent aspects in proportion to icterus. If icterus appears, they show markel changes with turbidity and necrosis, but without icterus they present only slight changes. 5. The neutralining antibody is easily proved in the immunized rabbits for about one year. 6. The passive immunity has the defense immunability until 10\ulcorner 7. Gunia pigs are easily infected with this virus and get the immunity. On fowls this virus can be kept in the blood for about ten days by various inoculating methods, and the fowls obtain the defensive ability by reinoculation, but are unable to succeed this ability from generation to generation. 8. when young swine are infected with this virus, their growth are disturbed and result in atrophied swine. It is therofor presumed that the etiology of the antigrowth of these atrophied swine is similar morphological and functional changes observed in the above rabbits.

  • Even though a flexible disk grinding process was often applied to enhance the product quality, it produced non-flat zone in the beginning and the exit (end) area. Since latter area is susceptible to poor product quality with burn mark, careful analysis is required to cope with such degradation. The flexible disk grinding exit stage was analyzed for workpiece length, wheel speed, depth of cut and feed. The exit stage qualities defined as exit stage ratio and exit stage angle or slope was characterized. A neural network application results reveled that exit stage characteristics was predicted more accurately without workpiece dimension with minimum error of 1.3%.

  • This study aims to introduce missile live-fire during the ship operational test and evaluation(T&E) as a means of verifying the integrated combat capability(ICC) of various systems installed on naval ships. The research method identified domestic and foreign T&E systems and cases, and reports related to ICC, which were written during the ship's design stage. As a result of research, Republic of Korea is not conducting the missile live-fire at the ship T&E stage due to the lack of relevant systems, while the U.S. is conducting it based on the mission-based T&E and the end-to-end test system. As a way to improve within the current domestic ship acquisition systems, the reaction time analysis, a quantitative analysis result of ICC calculated at the ship basic design stage, was proposed to be verified by missile live-fire during ship operational T&E.

  • Every one experiences death one day, however no one can knows exactly what it is because people can not experience death until it comes, it is therefore impossible to judge correctly on the phenomenon of the death. On the whole, man experiences indirect death through the mass communications such as TV drama, fiction, magazine etc because those methods can easily access by every one. In addition to this, people usually acquire the negative awareness of death through the dramatic change of story like dying of cancer for dramatic effect by giving scare and fear to the cancers. The purpose of this study is to provide basic information on the spiritual care that enables the facing death patients to accept death as a part of life and divert hope from scare about after death by comparing and analyzing of two aspects of death meaning I.e, Korean fiction and the end stage cancer patients. Additionally, for medical staff to understand the facing death cancer patients by making to aware patients correctly and provide the better quality of care. The study was performed from September 28, 2002 to February, 28 2003. The materials of this study were collected by direct data obtained from observation, interviews, note and diary of end stage of cancer patients and written materials acquired from Korean contemporary fiction. Participants of this study were 4 end stage cancer patients including 2 lung cancer patients, 1 liver cancer patient and 1 esophagus cancer patient. The methodology used in this study was divided into two types; Huberman & Miles methodology was used for fiction to find and categorize subject, and Colaizzi, one of phenomenological methodology was used for end stage cancer patients to find the major meaning, subject and categorization. 1.The death investigated in the fiction, was found as a progress of negative emotion, acceptance and sublimation, life related subjects in the negative emotion were tenacity for life, anxiety, lingering attachment, responsibility, abandonment and death related subjects were shock, isolation, fear, scare and rejection. Acceptance related subjects were acceptance, destiny, secularism, preparation and arrangement, and sublimation related subjects were sublimation through Christian and Buddhism. 2.The death showed in the participants was negative emotion, acceptance and sublimation, life related subjects were repentance, anxiety, responsibility and hopelessness, and death related subjects were dejection, solitude, anger, fear and scare. The acceptance was a type of religious acceptance that admitted instantly by reaching an understanding with the God, and death was accepted as a progress of preparation, arrangement, acceptance and hope. Sublimation related subjects were Christian sublimation and relief or destiny incurred from self-reflective sublimation through communications and thoughts. 3.The death in view of fiction and participants were positively accepted both death and negative emotion, and the study disclosed the fact that death was sublimated dependent on religion. 4.The progress of negative emotion, acceptance and sublimation was disclosed more complicated and various in the real end stage cancer patients and acceptance only found in the patients on the form of religious acceptance, according to the results compared with fiction and real end stage cancer patients. The death showed in the fiction was standardized, gradated and similar progress with psychological status of Kubler-Ross. However, death in the participants was showed complex and various feelings simultaneously, and sometimes they accepted death positively. The sublimation through religion was found in Buddhism and Christian in the fiction and mostly Christian in the participants due to a number of Hospice patients. It was found that negative emotion various types of death was more found in the participants than fiction. It is therefore necessary to study on the response of death in various types. In the participants death was incurred more systematic and variously, we knew that nursing practice focused on experience of participants is required and reality on death is much profound than we analyzed and presented, lots of situations and reactions should be premised because we can not completely rule out the negligence possibility of care mediation of participants. In caring for the facing death patients, we discovered and confirmed again through this study that the spiritual care should be needed as a mediation method.
