목적: 각막곡률계(keratometer) 측정값과 각막지형도(corneal topography) 검사에 의해 분류된 난시량에 따른 비구면 RGP 렌즈의 동적 움직임 차이를 알아보고자 하였다. 방법: 직난시를 가지고 있는 20~30대 남녀의 36안을 대상으로 각막곡률계를 이용하여 각막의 곡률을 측정하고 난시량에 따라 비구면 RGP 렌즈를 피팅한 후 회전량, 순목에 의한 수평 및 수직 방향으로의 이동거리를 측정하였으며 이를 각막지형도 검사를 이용하여 측정된 전체 각막 난시량을 기준으로 하여 피팅하였을 때 각막에서의 비구면 RGP렌즈 동적움직임과의 차이를 비교하였다. 결과: 각막곡률계로 측정하여 얻은 중심부 각막 난시량이 각막지형도 검사를 이용하여 얻은 전체 각막 난시량보다 더 크게 나타난 경우는 61.1%였으며, 그 반대의 경우는 36.1%로 중심부 각막 난시량이 언제나 전체 각막 난시량보다 크게 나타나는 것은 아니라는 것을 알 수 있었다. 또한, 전체 각막 난시량과 중심부 각막 난시량의 차이값이 0.25D 이상인 경우가 19안으로 52.8%에 해당하는 피검안 경우는 비구면 RGP 렌즈 처방이 틀려질 수 있음을 알 수 있었다. 각막곡률계에 의해 측정된 각막 난시량을 기준으로 하였을 때는 수평방향의 이동이 각막의 난시 정도에 따라 통계적으로 의미있는 차이를 나타내었으나 각막지형도에 의해 전체 각막 난시량으로 분류하였을 때는 비구면 RGP 렌즈의 회전양, 수직 및 수평 방향으로의 이동거리 모두 통계적으로 의미있는 변화가 없었다. 각막곡률계에 의해 측정된 중심부 각막 난시량이 각막지형도 검사에 의해 측정된 전체 각막 난시량에 비해 클 경우가 그 반대의 경우에 비해 렌즈의 회전량이 더 많았다. 또한, 각막의 곡률 반경이 다르더라도 각막 난시량에 의해 동일한 베이스커브를 가진 렌즈로 처방이 내려지는 동일처방의 경우에는 각막 난시량이 증가하면 비구면 RGP 렌즈의 회전량이 증가하는 경향을 보였다. 결론: 본 연구를 통해 각막곡률계와 각막지형도 검사를 이용하여 직난시안에 비구면 RGP 렌즈를 피팅하였을 때 각막에서의 동적움직임이 완전히 상이하지는 않았으며 특정 움직임에서는 차이가 있음을 알 수 있었다. 따라서 각막곡률계를 이용한 피팅의 성공률을 더 높이기 위해서 혹은 각막지형도 검사를 이용한 피팅의 적절한 적용을 위해서 피팅 방법들 간의 상관관계에 대해 더 많은 연구가 수행되어야 함을 알 수 있었다.

This study was done to provide information which would lead to nursing care of the elderly being more holistically through an understanding of the phenomena of powerlessness based on the lived experience of powerlessness by the elderly, the meaning the elderly give to such phenomena, and what essence of powerlessness is. The methodology used in this study was Max Van Manen's phenomenological method based on the philosophy of Merleu-Ponty and a concerted approach was realized through the 11 steps suggested in the Van Manen's method. Data collection was done from March 2, 1995 to December 30, 1995. The subjects for this study were four elderly persons who lived with their families and who were over 60 years of age. Data were collected about the lived experience of the elderly, this researcher's experience of powerlessness, the linguistic meaning of powerlessness, idioms of the word or a feeling of powerlessness, and descriptions of powerlessness in the elderly as they appeared in the literature, are works, and phenomenological literature. All data were used to provide insights into the phenomena of powerlessness. Data about the experience of powerlessness by the elderly were collected through open interviews, participation, and observation. In the analysis of the theme of this study, the aspects of the theme, powerlessness in the elderly were clarified, thereby abstracting and finding meaningful statements by the elderly about their feeling of powerlessness, and then those significant statements were expressed as linguistic transformations. The summarized findings from the study are as follows : 1. Five meanings of powerlessness in the elderly were defined. 〈weakness〉, 〈dependence〉, 〈frustration〉, 〈worthlessness〉 and 〈giving up〉. 2. 〈Weakness〉 means that the elderly experience, not only their aging but also, their becoming weak and the loss of physical function frequently caused by diseases. 〈Dependence〉 means that the elderly experience dependence without any influence from the surroundings and that elderly patients who are hospitalized lose their autonomy, follow entirely their doctor's prescriptions, use aid equipment and directions, and depend only on those things. 〈Frustration〉 means that the elderly experience the loss of their roles from the past, there by feeling that there is no work for them to do anymore and therefore feel unable to do anything. 〈Worthlessness〉 means that the elderly experience the feeling of losing their social roles from the past, having no financial ability, thereby being a burden to their children or the people around them, and therefore regarding themselves useless. 〈Giving up〉 means that the elderly experience the feeling of closeness to death in the final stage of their lifetime, lose hope to be healed from their disease, and recognize the incontrollability of their own body. 3. From a general view of the meaning of the theme the powerlessness in the elderly-the most essential meaning of the theme is the 〈sense of loss〉. For the elderly are experiencing a sense of loss in the situation of being elderly and therefore being often hospitalized. Brief definitions of the five phenomena could be 〈weakness〉 meaning the loss of physical strength, 〈dependence〉 the loss of mentality caused by disease and hospitalization, 〈frustration〉 and 〈worthlessness〉 the loss of social performance caused by the loss of social functions from the past, and lastly 〈giving up〉 the loss of the controllability of such situations of aging and suffering disease. In light of the discussion above, it is understandable that the hospitalized elderly experience powerlessness not only as it related to their diseases but also to their normal aging, and this related to other characteristics of being elderly means that the 〈sense of loss〉 is the very essence of their powerlessness. 4. While most cases are of the normal elderly experiencing powerlessness in relation to their social network, cases of elderly who are hospitalized are of those experiencing powerlessness in relation to the loss of their physical desire. 5. The findings discussed above can serve as guidelines for nurses who take care of the ill elderly who are hospitalized and that can provide cues to appropriate nursing service, recognizing that the subjective experience of the objective age of the elderly is so important. Nurses can provide highly qualitative nursing service, based on their deep understanding of the suffering of the elderly due to feelings of powerlessness.

'Sang Han Lon' became the sources for treatment and prescription in the Oriental medicine. After that, for some 1800 years the various writings for studying in many ways more than 1000 books which many old sages really intended to inquire into and study the value of books. It is considered that it is the result which the old sages tried to grope for many-sided directions in order to understand 'Sang Han Lon'. In this study, I tried to inquire into prescription and its relevant medicinal substances, that is to say, the crystalization of the physiology, pathology and treating method on the basis of the academic sources of his thoughts. The method to approach is "from what basis of thought system was 'Sang Han Lon' derived first of all?" Secondly, how was the thought system, which became the basis of 'Sang Han Lon', applied to concretely? I studied on the basis of the above important two problems. It is well known to everybody that 'Sang Han Lon' succeeded to the tradition of Naekyung(內經) as well as Cwuyek(周易, Chinese classic on divination). Besides, I inquired into and arrived at conclusion as follows that how the viewpoint on the balance(平衡觀), which was one of the common point between. Cwuyek(周易) and medical science in case of the 'Sanghan prescription'(傷寒方), was applied to concretely. 1. In naming, it is considered that from the same interconnection which the common point with Cwuyek(周易) was the same as obtaining the imigination(取象), the imagination was obtained and was named. 2. In case of being concerned in the gastro-intestinal track, namely, the core of the balance and harmony with the balance and harmony being emphasized, '理中'(It implies 'taking care of gasstro-intestinal track')" and '建中'(It implies 'establishing of gastro-intestinal track'), that is to say, '中'(It implies 'taking care of' & 'establishing of gastro-intestinal track') was emphasized much more. 3. In case of treatment taking advantage of three kinds of medicine in draught, powder and pills in the prescription, while treating during adjusting the slowness and fastness, I maintained the harmony not to damage the righteousness(正氣). 4. In case of the prescription, when exhaling(發散), astringing(收斂), loosing bowels, protecting the gastro-intestinal track and vomitting, he used the medicinal sustances in order to protect the gastro-intestinal track and treated not to damage the righteousness. 5. Especially, in case of the prescription in order to adjust the negative and positive principle of inside-outside(素囊陰陽), he composed of medicinal substances relevant to hot, cold, spicy and sour(寒熱辛酸) in conformity with the prescription and I paid much more attention to the one-sided treatment. Considering the various prescriptions, it is regarded that the adjusting prescription is kept its balance. 6. In the way of processing the medicinal substances in order to change effect of medicine in conformity with the reenactment, he tried to plan the balance of '一升一降' with the decrease of RHEI RADIX ET RHIZOMA(大黃) and increase of wine. 7. In boiling the medicine, he boiled the composed medicine in the time sequence for the purpose of adjusting the slowness and fastness and adapted to harmony of the negative and positive principle(陰陽調和) on the essence function(體峻用純). 8. In taking medicine, he tried to reduce the time of taking the medicine in case of being boiled slowly and tried to increase the dosage and eventually he planned the balance of one time slowness and one time fastness. As I inquired into the above result, a few steps for protecting method to boil the relevant medicinal substances, how to take the medicine and how to process the composed medicinal substances in order to change the effect of medicine can make the human body, which the disease penetrate into, go forward to the righteousness(正氣) and what is much beter, it is considered that this protecting method can be a carefully considerable one in order to protect the righteousness and can subdue the disease, not to damage the gastro-intestinal track and there can exist the viewpoint of balance(平衡觀) on its core.

This study was done to compile 104 experimental theses which are related to the antitumor and immuno-activating therapies between February 1990 through February 2002. Master's and doctoral theses were dassified by schools, degrees, materials, effects, experimental methods of antitumor and immunoactivity, and results. The following results were obtained from this study : 1. Classifying the theses by the school, 34.6% were presented by Daejeon University, 29.8% by Kyung-hee University and 11.5% by Won-kwang University. Of all theses, 51.0% were aimed for the doctoral degree and 43.3% were for the master's degree. All of three universities have their own cancer centers. 2. Classifying the theses by herb materials, complex prescription accounted for 60.3%, single herb accounted for 24.8% and herbal acupuncture accounted for 14.2%. Considering the key principles of the traditional medicine, complex prescription was much more thoroughly studied than single herb prescription. The results showed that the complex prescription had both antitumor activity and immuno-activating activity, which might reflects on multi-activation mechanisms by complex components. 3. Classifying the theses by the efficacy of herbs examined, in single herb, invigorating spleen and supplementing was 35.5%, expelling toxin and cooling was 29.0%, activating blood flow and removing blood stasis was 12.9%. In herbal acupuncture, invigorating spleen and supplementing was 52.9%, expelling toxin and cooling was 29.4%. In complex prescription, pathogen-free status was 41.9%, strengthening healthy qi to eliminate pathogen was 35.5%, strengthening healthy qi was 22.6%. It is presumed that the antitumor and immunoactivating therapy based on syndrome differentiation is the best way to develop oriental oncology. 4. Classifying the theses by antitumor experiments, cytotoxic effect was 48.1 %, survival time was 48.1 % and change of tumor size was 42.3%. Survival rate was not necessarily correlated with cytotoxicity. These data reflect the characteristic, wholistic nature of the oriental medicine which is based on BRM (biological response modifier). 5. Classifying the theses by immunoactivating experiments, hemolysin titer was 51.0%, hemagglutinin titer was 46.2% and NK cell's activity was 44.2%. In the future studies, an effort to elucidate specific molecular and cellular mechanisms of cytokine production in the body would be crucial. 6. Classifying the theses according to the data in terms of antitumor activity, 50% was evaluated good, 24.0% was excellent, and 15.5% have no effect. In an evaluation of immuno-activating activity, 35.9% was excellent and 18.0% showed a little effect. The index point, as described here, may helps to use experimental data for clinical trials. Changes in index points by varying dosage implicate the importance of oriental medical theory for prescription. 7. In 167 materials, IIP (immunoactivating index point, mean : 3.12±0.07) was significantly higher than AIP(antitumor index point, mean : 2.83±0.07). These data demonstrate that the effect of herb medicine on tumor activity depends more on immunoactivating activity than antitumor activity. This further implies that the development of herbal antitumor drugs must be preceded by the mechanistic understanding of immunoactivating effect. 8. After medline-searching tumor and herb-related articles from NCBI web site, we conclude that most of the studies are primarily focused on biomolecular mechanisms and/or pathways. Henceforth, we need to define the biomolecular mechanisms and/or pathways affected by herbs or complicated prescriptions. 9. Therefore, the most important point of oriental medical oncology is to conned between experimental results and clinical trials. For the public application of herbal therapy to cancer, it is critical to present the data to mass media. 10. To develop the relationship of experimental results and clinical trials, university's cancer clinic must have a long-range plan related to the university laboratories and, at the same time, a regular consortium for this relationship is imperative. 11. After all these efforts, a new type herbal medicine for cancer therapy which is to take care of the long-term administering and safety problem must be developed. Then, it would be expected that anti-tumor herbal acupuncture can improve clinical symptoms and quality of life (QOL) for cancer patients. 12. Finally, oriental medical cancer center must be constructed in NCC (National Cancer Center) or government agency for the development of oriental medical oncology which has international competitive power.

Objective : This study was conducted to investigate the effects of Hwangryunhaedok-Tang and Geongangbuja-Tang on the change of interleukin-6 (IL-6) and tumor necrosis $factor-{\alpha}$ ($TNF-{\alpha}$) level induced by LPS I.C.V. injection in mice. Method : We devided group into 6 mice and 6 mice were assingned to each group. In the normal group only saline was administered intragastrically, and in the control group LPS was injected intracerebroventricularly 1 hr after intragastric administration of saline. In the experiment groups Hwangryunhaedok-Tang(0.5g/kg, 1.0g/kg, 3.0g/kg) was administered intragastrically to mice 1 hr prior to LPS(100mg/mouse) I.C.V. injection.. Also Geongangbuja-Tang (0.5g/kg, 1.0g/kg, 3.0g/kg) was administered intragastrically to mice 1 hr prior to LPS(100mg/mouse) I.C.V. injection. To measure the plasma IL-6 and $TNF-{\alpha}$ level of mice, their blood samples were collected from retro-orbital plexus, immediately centrifuged at $4^{\circ}C$, and plasma was removed and stored frozen at $-83^{\circ}C$ for later determination of IL-6 and $TNF-{\alpha}$. The level of IL-6 and $TNF-{\alpha}$ production was measured by enzyme-linked immunosorbent assay in the plasma. Result : Regarding IL-6 level, The 0.5g/kg and the 1g/kg groups of Geongangbuja-Tang decreased IL-6 level. Especially the 3g/kg control group decreased IL-6 level significantly than the normal group(p<0.01). Regarding $TNF-{\alpha}$ level, the 3g/kg group of Geongangbuja-Tang decreased it significantly(p<0.05). Conclusion : These data revealed that Hwangryunhaedok-Tang might not have the anti imflammatory effect and Geongangbuja-Tang(3g/kg)might have the anti imflammatory effect by reducing the plasma IL-6 and $TNF-{\alpha}$ level in mice LPS Injection.EIM (Eighteen Incompatible Medicaments) is an important component in Oriental pharmacology and is directly related to clinical prescriptions. Medical practitioners argued that the definite cause and meaning of EIM was ambiguous and therefore debated the issue of clinical application of the EIM. This study conducted an in-depth literary research on the origin, meaning and contents of EIM with the purpose to contribute in its efforts to be used clinically. Even after thousands of years have past since establishment of Oriental medicine, EIM is still tabooed and was an obstacle that hindered ideologies. Modern herbal medicine texts claim that the use of EIM can reduce treatment effects and promote poisoning and side effects. However, since long ago, there has been medical practitioners who reject this as false. Recently, poisoning caused by EIM has been claimed to be from the toxicity of the drug itself, rather than the result of interaction between the drugs, and therefore they suggest that EIM is not a forbidden domain. In addition, EIM showed a difference in number depending on the era. However, this can be understood not as a definite number, but instead as a warning to be careful during combination of drugs for use as clinical medicine. Historically, there were very few cases in which EIM was used for clinical tests and thus, the clinical value is not, while others applied EIM directly to their bodies, which showed signs for the usefulness and potential of EIM for us. A more concrete and in-depth study must be made on EIM.

The job related activities of sixty nine nurses, working in the emergency rooms of three university hospitals, were analyzed for six days according to preestablished checklist of nursing activities ; the frequency of these activities and the amount of time spent in each specific nursing activity. The established checklist was monitored every five minutes for the duration of the duty autu, thus producing 414 items of data. The data were not gathered on consecutive days but over the period of one month from May 6, 1994 to June 5, 1994. The following conclusions are derived from analysis of the data : 1. Twelve categories of nursing activities were obtained : The primary activity was communication related to the patient and all information pertaining to the patient. Other activities included maintaining the patient's record, observation and assessment of the patient, cooperation with other medical personnel, management of equipment and drugs, procedure and treatment, specimen collection, consultation and education for the patient, including drug management and personal hygiene and any other relevant education to the patient's condition. 2. The average frequency of categorized nursing activity can be classified as follows : communication related to patient was the highest at 17.6 times. The next was maintaining the patient's record at 17.3 times. The observation and assessment occurred 16.9 times. Consultation and education for patients and family, 8 times, medication, 5.7 times, and procedures and treatments, 6 times. 3. The average time required for each activity was as follows : 230.1 minutes (or maintaining the patient's record, 204.9 minutes for communication related to the patient, 199.2 minutes for observation and assessment, 71.2 minutes for medication, 66 minutes for consultation and education of the patient and family, and 51.8 minutes for procedures and treatment. 4. The most demanding nursing activity in the emergency room for the nurse was answering questions from the patient's family, maintaining communication between the medical staff, maintaining and reviewing the patient's charts, writing prescriptions and monitoring 1.

The most time consuming nursing activities for the emergency room nurse include maintaining and following the patient's charts, communication between the medical staff, answering questions from the patient's family, observation of the patient and relaying all of the appropriate patient information to the incoming nurses during a shift change. 6. The F-test was administered to measure the required time for the categorized nursing activities according to day, evening, and night-shift nurses. There were significant differences (p<.05) in specimen collection, observation and assessment, cooperation between medical staffs, personal hygiene, communication related to patient, education and re-search. Posterior multiple comparison test showed that specimen collection, cooperation between medical staffs and personal hygiene were mostly done by the evening-shift nurses. Also most observations and assessments were done by the night-shift nurses. Education and communication to patients were done by day-shift nurses. Thus there were significant difference between shifts for the main nursing activities. So there should considev a reallocation of the duty of nurses on each shift. 7. The F-test also indicated that there wes a similarity in time duration for procedures and treatments and for cooperation between medical staff and nurses in all three hospitals. However, the remaining categories of nursing activities also showed a significant difference between the three hospitals. This indicated that there were differences in each emergency room that influence time for each categorized nursing activities and this should be given more consideration. Recommendations : 1. A seasonal difference should be considered in the activities of nurses in the emergency room and a comparative analysis should be carried out to deter-mine seasonal differentiation. 2. A study on more objectively measurable nursing activities should be administered as well as one determining the subjective responds towards nursing activities in the emergency room.
