KASI (Korea Astronomy and Space Science Institute) has been developing the multipurpose laser tracking system with three functions of satellite laser tracking, adaptive optics and space debris laser tracking for scientific research and national space missions. The space debris laser tracking system provides the distance to space debris without a laser retro-reflector array by using a high power pulse laser, which employs a spinning disk to change the optical path between the transmit and receive beams. The spinning disk causes the collision band which is unable to reflect the returned signal to a detector and then has an effect on the tracking coverage of space debris. This study proposed the mathematical model for tracking coverage by taking into account the various specifications of spinning disk such as disk size, spinning velocity and collision rate between the disk and hole. In addition, the spinning disk specifications were analyzed in terms of tracking coverage and collision band based on the mathematical model to investigate tracking requirements of the Geochang laser tracking system.

1. Ounyukki(五運六氣) theory was first developed from observation of astronomical phenomena. Natural phenomena were explained and incorporated into the concepts of Yukki(六氣), and Ohaeng(五行, the concept that all matter in the world are comprised of five fundamental elements), during Chon-guk(戰國) and Han(漢) periods. In that period. Kanji(干支, the method to present time with ten and twelve different kinds of symbol's combinations) was used to record Ounyukki(五運六氣). Theoretical study of Un-gi(運氣, the abbreviation of Ounyukki) was almost completed in Un-gichilpyon(運氣七篇) of Naekyong(內經). Un-gi(運氣) theory was further studied and considered to be very important socially, as well as medically, in Tang(唐), Song(宋), Kum(金), and Won(元) periods. Hagan(河間) published various studies based on Un-gi(運氣) theory in Kum won(金元) periods. 2. Hagan(河間) realized the limitation of a remedy method, of Sanghan(傷寒) theory. Therefore, he made an assumption that the prevalence of diseases in his period are closely related to Hwayol(火熱, a fire and a super-heat; two things out of Yukki(六氣)). His new theory was a result of the study on Kyongjon(經典, bibles of the oriental medicine) and the phenomena of nature. 3. Hagan(河間) used a combination of two basic theories of Pimuripsang(比物立象) and Hanhaesungjeron(亢害承制論) to make understood Hwayol(火熱) theory, Pimuripsang(比物立象) theory explains a method to appreciate the essence of things by comparing Sang(象, an expression of how something appears on the outside) and then making another Sang(象) from the comparison. Hanhaesungjeron(亢害承制論) is a theory to emphasize the importance of a balance of Yukki(六氣). It is that, if one of the elements is exceeded, other thing in the other five elements dominate the exceeded thing to control it for the balance between Yukki(六氣). In addition, he articulated P'yobon(標本. inside and outside of a thing) theory to differentiate the disease symptoms. These theories will help to distinguish real and fake symptoms of diseases, on which Hagan(河間) emphasized its importance. 4. Hagan(河間) published a new theory to explain Ounyukki(五運六氣) theory based on the observation of the nature and the experience from medical practice. And he added Chobyonggi(燥病機, course and rule causing disease in dry conditions) to Pyonggishipkujo(病機十九條, nineteen course and rule causing disease), it strengthened Pyonggi(病機, course and rule causing disease) theories. Moreover. he utilized Un-gi (運氣) theory in a real life situation by applying Un-giron(運氣論) to diagnosis like Maekchin(脈診, a method to diagnose by taking the pulse) and to prescription. 5. Modern society is an era in which it is hard to appreciate the principles of the changes due to the various unusual weather. Therefore, it is necessary to make a new paradigm using Un-gi(運氣) theory, like Hagan(河間) did in Kumwon(金元) period. 6. Unusual weather changes and the geriatric diseases such as cancer and diabetes, may have Sang(象) of Hwayol(火熱) theory at the other side. These diseases have been and will create more serious problems in modern society. As a method to solve these problems. it seems to be very important to understand and apply Hagan's(河間) Hawyol(火熱) theory to modern society.

In order to study the factors influencing upon right medication of antibiotic for the consumers who can easily buy antibiotic from pharmacy, the study carried out questionnaires to 568 consumers who bought antibiotics from pharmacies located in Seoul And Kyung-gi do from the 1st of February, 1994 to the 28th of the same month. Materials have been analyzed with $X^-test$ of SAS, and its results are as follows. 1. Among 568 objects of this study, the group which can medicare antibiotic properly (the right use group of antibiotic) is 45.5% with 258, while the group which does not recognize correctly the use of antibiotic or does not have any information about it (the abuse group of antibiotic) is 54.6% with 310. 2. Knowledge for advantage of antibiotic the right use group has is high in comparing with that of the abuse group (p<0.001), and also in case of pregnancy, understanding for an adverse reaction of antibiotic is high (p<0.001). The right use group has had many chances to take health education (p<0.001), and the way to buy antibiotic is very safe (p<0.001). But there is no outstanding difference for recognition of an adverse reaction of antibiotic between two groups. 3. In comparing with the abuse group, the right use group keeps well taking time of antibiotics as directions (p<0.001), and keeping rate of antibiotic dosage is high (p<0.001). Also the experiences of an adverse reaction of antibiotic is low (p<0.001). 4. In comparing with the abuse group, the right use group has high educational backgrounds (p<0.001) and many experiences of the education for health promotion (p<0.001), while there is no difference in age, sex, and economic status. 5. In comparing with the abuse group, the right use group has taken antibiotic many times (p<0.001), and there are many antibiotic takers of his/her family (p<0.01). 6. In comparing with the abuse group, the right use group has made much effort not only to check blood pressure and the pulse (p<0.05) but also for food habits (p<0.05). But there is no outstanding difference in the effort to get health information and the effort for regular exercises between these two group. 7. In comparing with the abuse group, the right use group has made an exertion in buying foodstuffs (p<0.001). But there is no big difference in efforts to keep the good attitude for physical health and mental heath, and sleeping hours between these two group.

A 47-year-old-man was admitted to the emergency department with dyspnea, right pleuritic pain, and high fevers for 3 days. He had a nonproductive cough that exacerbated the chest pain. A clinical examination revealed distressed and slightly tachypneic patient, with blood pressure of 110/90 mmHg, temperature of $39^{\circ}C$, pulse of 90 beats/min, respiratory rate of 24 breaths/min. A chest examination showed significantly diminished breath sounds in the right lung with dullness to percussion. Laboratory investigation demonstrated leukocytosis and a raised C-reactive protein. The results of arterial blood gas analysis revealed moderate hypoxemia. A radiograph and a CT scan of the chest showed extensive consolidation with multifocal low densities, and pleural effusion in the right lung. A diagnostic thoracentesis revealed straw-colored fluid, which was found to be a neutrophil-predominant exudate. At 7 days after admission, the clinical symptoms had not improved and the temperature was still $39^{\circ}C$ despite the aggressive therapy of community-acquired pneumonia. After comprehensive history taking, we realized then that he accidentally aspirated kerosene while siphoning from fuel tank to put into the boiler 3 days ago. Bronchoscopy with bronchial washings could be successful in establishing the diagnosis of hydrocarbon pneumonitis by demonstration of a high lipid-laden macrophage index. Thereafter, the symptoms and radiographic opacities gradually improved, and he was discharged several days later.

Purpose: Damage to pulse crops by wild birds is a serious problem. The damage is to such an extent that the rate of damage during the period between seeding and cotyledon stages reaches 54.6% on an average. In this study, a crop-position detection method was developed wherein infrared (IR) sensors were used to determine the cotyledon position under a vinyl mulch. Methods: IR sensors that helped measure the temperature were used to locate the cotyledons below the vinyl mulch. A single IR sensor module was installed at three locations of the crops (peanut, red lettuce, and crown daisy) in the cotyledon stage. The representative thermal response of a $16{\times}4$ pixel area was detected using this sensor in the case where the distance from the target was 25 cm. A spatial image was applied to the two-dimensional temperature distribution using a non-integral moving-average method. The collected data were first processed by taking the moving average via interpolation to determine the frame where the variance was the lowest for a resolution unit of 1.02 cm. Results: The temperature distribution was plotted corresponding to a distance of 10 cm between the crops. A clear leaf pattern of the crop was visually confirmed. However, the temperature distribution after the normalization was unclear. The image conversion and frequency-conversion graphs were obtained based on the moving average by averaging the points corresponding to a frequency of 40 Hz for 8 pixels. The most optimized resolutions at locations 1, 2, and 3 were found on 3.4, 4.1, and 5.6 Pixels, respectively. Conclusions: In this study, to solve the problem of damage caused by birds to crops in the cotyledon stage after seeding, the vinyl mulch is punched after seeding. The crops in the cotyledon stage could be accurately located using the proposed method. By conducting the experiments using the single IR sensor and a sliding mechanical device with the help of a non-integral interpolation method, the crops in the cotyledon stage could be precisely located.

I examined throughout where Sa Gi Gang Boo Byung Hyung(邪氣藏府病形) was shown. It is shown in many books, such as Young Chu(靈樞), Kab Eul Kyung(甲乙經), Nan Kyung(難經), Yu Kyung(類經), etc. Sa Gi Gang Boo Byung Hyung got its name by how its contents pointed to the mechanism of getting harmed by Sa Gi(邪氣), and the forms of diseases which were led from five organs and six hollow viscera getting harmed by Sa Gi(邪氣). Sa Gi Gang Boo Byung Hyung is divided into three chapters which are divided altogether into nine sections. The first chapter is on the mechanism of Sa Gi(邪氣)' s harming the five organs and the six hollow viscera. Going into details, it discusses that Sa Gi has got two different ways which are divided into Yum Yang(陰陽) to harm the organs and the hollow viscera. Next, it discusses how faces can endure the cold that well. The second chapter is on the essences such as symptoms, face colors, shapes of pulse, and conditions on the interior part of the elbow. In the first section, it discusses how figures, colors and pulses relate together. In the second section, it discusses different diseases have different pulses and conditions on the interior part of the elbow. The third section is on forms of diseases in five organs and six hollow viscera. The third chapter is on acupuncture. The first section is about acupuncturing six channels. The second is about acupuncture points which is compared to the sea by its function. The third is about the forms of diseases with discussing symptoms and acupuncture points. The forth is about the essence of acupuncture. The ten different pulses of each five organs, and the masses of five organs in Nan Kyung(難經), and Jang Bu Mak Jin Beob(臟腑脈診法) in Eu Hak Yib Moon(醫學入門) are based on 'The six different pulses of each five organs' which is shown in the third section, second chapter. Besides, it plays an important role in study and it can play an important role as well in doctoring such as inspecting, taking pulses and so on. Thus, I found Sa Gi Gang Boo Byung Hyung worth while to study. But, Sa Gi Gang Boo Gyung Hyung was written in ancient letters and was omitted in many parts, which led successive doctors to write different explanatory notes. Thus, I researched the exact meaning through successive explanatory notes.

The purpose of this study is to investigate the recognition of "Jung Pung(中風)" mentioned in "Jae-Byoung-Won-Hu-Ron(諸病源候論)" The conclusion would be summerized as follows. 1. "Pung Byoung(風病)" is a symptom that man was damaged by "Pung Chi(風氣)", which is a wide meaning inclusive of cloudiness of conscious, apasia and the limbs disorder of "Jung Pung(中風)", "Bi 痺symptom", "Yeuk Jeil Pung(歷節風)", the skin disease, psychopathy and leprosy. 2. In cause of "Jung Pung(中風)", this book was received the theory of invasion of "Pung Sa (風邪)" from outside claimed in "Nae Kyoung(內經)", "Kum Gaeu Yo Rak(金?要略)", but in a viewpoint of "Hyel Chi(血氣)", "Young Yui(營衛)" and "Bi Yui Heo Sil(脾胃虛實)", especially, insists on the weakness of "Bi Yui(脾胃)" function. 3. In the pathology of "Jung Pung(中風)", there was a recognition that symptoms appear following each "Jang Bu(臟腑)" invaided and changed by a way of "Kyoung Rak Jang Bu(經絡臟腑)", because "Pung Sa(風邪)" invades the space of the skin, disturbs the circulation of "Hyel Chi(血氣)" in a inner and isn't given out in a outer. 4. Thereare, , , , , in the symptoms of "Jung Pung(中風)" and ", , , , , , in the similar symptoms of "Jung Pung(中風)". 5. The principle of treatement is "getting sweating, helping the insufficent energy and diminishing the sufficent energy", but the presciption isn't mentioned and "Do-in Method(導引法)" was recorded after each symptom because of taking a serious view of "Bo-Yang-Sun-Do(補養宣導)" 6. The prognosis of "Jung Pung(中風)"is suggested in a view of pulse diganosis, symptoms and is bad in case of appearance of no sweating, rigidity, vomitting a bubble and apasia.

A 15 kg 6-year-old intact male Jindo dog with a history of a respiratory distress, hindlimb paralysis with necrosed skin of dorsal digit for three weeks was referred to Animal Medical Center, Chonbuk National University. Heartworm infection was identified by kit examination. In plain thoracic radiographs, dilated pulmonary arteries reverse D sign and focal interstitial pattern was compatible with heartworm infection and possible pulmonary thromboembolism. Abdominal radiographs showed poor serosal detail indicating fluid accumulation within peritoneal cavity. No evidence of musculoskeletal abnormalities was found. Ultrasonography presented focal wedge-shaped hyperechogenecity on the both poles of left kidney, weak or absent pulse on the distal to the external iliac artery as well as ascites and irregular liver margin. Multi-organ failure was strongly supposed by blood profile including leukocytosis, anemia, hemoglobinuria bililubinemia, hypoalbuminemia, imbalance of electrolytes, and increased hepatic and renal function values. Interestingly, the glucose level is remarkably lower in pelvic limb compared to thoracic limb. Suspected pulmonary thromboembolism, renal infarction and femoral arterial embolization causing hindlimb paralysis and dermatic necrosis were confirmed by 3D reconstructed CT imaging. Prior to taking a consideration of euthanasia, interventional radiology was experimentally attempted but failed due to not recovered from general anesthesia. Early and accurate diagnosis of thromboembolism is valuable and 3D reconstructed CT images might be very useful to show the correct way to treat effectively.

Background : Although the long term adverse effects of cigarette smoking on health are well known, the acute possible detrimental effects of smoking on pulmonary or cardiovascular function, especially when these systems are stressed by the metabolic demands of exercise, have not been well studied The purpose of this study is to determine the acute action of cigarette smoking on cardiopulmonary function under stress. Method : Twenty -one healthy smoking subjects were studied. Before exrecise testing, history taking, physical examination and baseline studies, including CBC, chest PA, PFT and EKG, were done. The subjects performed an incremental bicycle exercise test to exhaustion on two occasions, one without smoking and the other after smoking 5 cigarettes/h for 2 hours. All indices of P.F.T. and bicycle ergometry were compared between before and after smoking. Results : 1. $VO_2$max and $O_2$ pulse showed significant decrease in smoking day. 2. Although there were no significant differences, anaerobic threshold showed a tendency of decrease and HRmax showed that of increase in smoking day. 3. P.F.T. and respiratory indices showed no significant change io smoking day. Conclusion : Cigarette smoking has immediate adverse effect, especially on the cardiovascular system rather than the respiratory system. These results would be due to the effect of elevated HbCO and/or impaired blood flow in response to the exercise stimulus.
