  • Much has teed changed in the field of hospital administration in the It wake of the rapid development of sciences, techniques ana systematic hospital management. However, we still have a long way to go in organization, in the quality of hospital employees and hospital equipment and facilities, and in financial support in order to achieve proper hospital management. The above factors greatly effect the ability of hospitals to fulfill their obligation in patient care and nursing services. The purpose of this study is to determine the optimal methods of standardization and quality nursing so as to improve present nursing services through investigations and analyses of various problems concerning nursing administration. This study has been undertaken during the six month period from October 1971 to March 1972. The 41 comprehensive hospitals have been selected iron amongst the 139 in the whole country. These have been categorized according-to the specific purposes of their establishment, such as 7 university hospitals, 18 national or public hospitals, 12 religious hospitals and 4 enterprise ones. The following conclusions have been acquired thus far from information obtained through interviews with nursing directors who are in charge of the nursing administration in each hospital, and further investigations concerning the purposes of establishment, the organization, personnel arrangements, working conditions, practices of service, and budgets of the nursing service department. 1. The nursing administration along with its activities in this country has been uncritical1y adopted from that of the developed countries. It is necessary for us to re-establish a new medical and nursing system which is adequate for our social environments through continuous study and research. 2. The survey shows that the 7 university hospitals were chiefly concerned with education, medical care and research; the 18 national or public hospitals with medical care, public health and charity work; the 2 religious hospitals with medical care, charity and missionary works; and the 4 enterprise hospitals with public health, medical care and charity works. In general, the main purposes of the hospitals were those of charity organizations in the pursuit of medical care, education and public benefits. 3. The survey shows that in general hospital facilities rate 64 per cent and medical care 60 per-cent against a 100 per cent optimum basis in accordance with the medical treatment law and approved criteria for training hospitals. In these respects, university hospitals have achieved the highest standards, followed by religious ones, enterprise ones, and national or public ones in that order. 4. The ages of nursing directors range from 30 to 50. The level of education achieved by most of the directors is that of graduation from a nursing technical high school and a three year nursing junior college; a very few have graduated from college or have taken graduate courses. 5. As for the career tenure of nurses in the hospitals: one-third of the nurses, or 38 per cent, have worked less than one year; those in the category of one year to two represent 24 pet cent. This means that a total of 62 per cent of the career nurses have been practicing their profession for less than two years. Career nurses with over 5 years experience number only 16 per cent: therefore the efficiency of nursing services has been rated very low. 6. As for the standard of education of the nurses: 62 per cent of them have taken a three year course of nursing in junior colleges, and 22 per cent in nursing technical high schools. College graduate nurses come up to only 15 per cent; and those with graduate course only 0.4 per cent. This indicates that most of the nurses are front nursing technical high schools and three year nursing junior colleges. Accordingly, it is advisable that nursing services be divided according to their functions, such as professional, technical nurses and nurse's aides. 7. The survey also shows that the purpose of nursing service administration in the hospitals has been regulated in writing in 74 per cent of the hospitals and not regulated in writing in 26 per cent of the hospitals. The general purposes of nursing are as follows: patient care, assistance in medical care and education. The main purpose of these nursing services is to establish proper operational and personnel management which focus on in-service education. 8. The nursing service departments belong to the medical departments in almost 60 per cent of the hospitals. Even though the nursing service department is formally separated, about 24 per cent of the hospitals regard it as a functional unit in the medical department. Only 5 per cent of the hospitals keep the department as a separate one. To the contrary, approximately 12 per cent of the hospitals have not established a nursing service department at all but surbodinate it to the other department. In this respect, it is required that a new hospital organization be made to acknowledge the independent function of the nursing department. In 76 per cent of the hospitals they have advisory committees under the nursing department, such as a dormitory self·regulating committee, an in-service education committee and a nursing procedure and policy committee. 9. Personnel arrangement and working conditions of nurses 1) The ratio of nurses to patients is as follows: In university hospitals, 1 to 2.9 for hospitalized patients and 1 to 4.0 for out-patients; in religious hospitals, 1 to 2.3 for hospitalized patients and 1 to 5.4 for out-patients. Grouped together this indicates that one nurse covers 2.2 hospitalized patients and 4.3 out-patients on a daily basis. The current medical treatment law stipulates that one nurse should care for 2.5 hospitalized patients or 30.0 out-patients. Therefore the statistics indicate that nursing services are being peformed with an insufficient number of nurses to cover out-patients. The current law concerns the minimum number of nurses and disregards the required number of nurses for operation rooms, recovery rooms, delivery rooms, new-born baby rooms, central supply rooms and emergency rooms. Accordingly, tile medical treatment law has been requested to be amended. 2) The ratio of doctors to nurses: In university hospitals, the ratio is 1 to 1.1; in national of public hospitals, 1 to 0.8; in religious hospitals 1 to 0.5; and in private hospitals 1 to 0.7. The average ratio is 1 to 0.8; generally the ideal ratio is 3 to 1. Since the number of doctors working in hospitals has been recently increasing, the nursing services have consequently teen overloaded, sacrificing the services to the patients. 3) The ratio of nurses to clerical staff is 1 to 0.4. However, the ideal ratio is 5 to 1, that is, 1 to 0.2. This means that clerical personnel far outnumber the nursing staff. 4) The ratio of nurses to nurse's-aides; The average 2.5 to 1 indicates that most of the nursing service are delegated to nurse's-aides owing to the shortage of registered nurses. This is the main cause of the deterioration in the quality of nursing services. It is a real problem in the guest for better nursing services that certain hospitals employ a disproportionate number of nurse's-aides in order to meet financial requirements. 5) As for the working conditions, most of hospitals employ a three-shift day with 8 hours of duty each. However, certain hospitals still use two shifts a day. 6) As for the working environment, most of the hospitals lack welfare and hygienic facilities. 7) The salary basis is the highest in the private university hospitals, with enterprise hospitals next and religious hospitals and national or public ones lowest. 8) Method of employment is made through paper screening, and further that the appointment of nurses is conditional upon the favorable opinion of the nursing directors. 9) The unemployment ratio for one year in 1971 averaged 29 per cent. The reasons for unemployment indicate that the highest is because of marriage up to 40 per cent, and next is because of overseas employment. This high unemployment ratio further causes the deterioration of efficiency in nursing services and supplementary activities. The hospital authorities concerned should take this matter into a jeep consideration in order to reduce unemployment. 10) The importance of in-service education is well recognized and established. 1% has been noted that on the-job nurses. training has been most active, with nursing directors taking charge of the orientation programs of newly employed nurses. However, it is most necessary that a comprehensive study be made of instructors, contents and methods of education with a separate section for in-service education. 10. Nursing services'activities 1) Division of services and job descriptions are urgently required. 81 per rent of the hospitals keep written regulations of services in accordance with nursing service manuals. 19 per cent of the hospitals do not keep written regulations. Most of hospitals delegate to the nursing directors or certain supervisors the power of stipulating service regulations. In 21 per cent of the total hospitals they have policy committees, standardization committees and advisory committees to proceed with the stipulation of regulations. 2) Approximately 81 per cent of the hospitals have service channels in which directors, supervisors, head nurses and staff nurses perform their appropriate services according to the service plans and make up the service reports. In approximately 19 per cent of the hospitals the staff perform their nursing services without utilizing the above channels. 3) In the performance of nursing services, a ward manual is considered the most important one to be utilized in about 32 percent of hospitals. 25 per cent of hospitals indicate they use a kardex; 17 per cent use ward-rounding, and others take advantage of work sheets or coordination with other departments through conferences. 4) In about 78 per cent of hospitals they have records which indicate the status of personnel, and in 22 per cent they have not. 5) It has been advised that morale among nurses may be increased, ensuring more efficient services, by their being able to exchange opinions and views with each other. 6) The satisfactory performance of nursing services rely on the following factors to the degree indicated: approximately 32 per cent to the systematic nursing activities and services; 27 per cent to the head nurses ability for nursing diagnosis; 22 per cent to an effective supervisory system; 16 per cent to the hospital facilities and proper supply, and 3 per cent to effective in·service education. This means that nurses, supervisors, head nurses and directors play the most important roles in the performance of nursing services. 11. About 87 per cent of the hospitals do not have separate budgets for their nursing departments, and only 13 per cent of the hospitals have separate budgets. It is recommended that the planning and execution of the nursing administration be delegated to the pertinent administrators in order to bring about improved proved performances and activities in nursing services.

  • Muscle weakness in the hemiplegia following stroke is an important factor which determines the quality of life in the future. Therefore, muscle strengthening exercise is essential for functional recovery in hemiplegic patients. Even though the popular conception is that muscle strengthening exercise causes spasticity and associated reaction that hemiplegia patients don't want, and that it disturbs functional recovery, recently there have been many new reports against that opinion. Therefore, the effects of strengthening exercise programs on functional recovery in hemiplegic patients are still controversial. The purpose of this study was to determine the effects of strengthening exercise programs for the knee joint using isokinetic exercise on the associated reaction of the upper extremities. Comparing the muscle activities of biceps brachii and triceps brachii during, before, and immediately after 2 and 5 minute intervals of isokinetic exercise, we examined the increase and decrease of associated reaction. Twenty stroke inpatients participated in this study. Surface electromyography was used to get muscle activity data from biceps brachii and triceps brachii. The major findings of this study were as follows: 1. The flexor and extensor peak torque were significantly higher on the sound side than the affected side (p<.05). 2. Before and after strengthening exercise, there was no significant difference in muscle activities (surface electromyographic root mean square values) between the sound and affected side. 3. Muscle activities were examined during, before, and immediately after 2 and 5 minute intervals of isokinetic exercise. There were significant differences in muscle activities between, before and during the exercises, during exercise and 5 minutes after exercise in the biceps brachii (p<.05), and during exercise and 5 minutes after exercise in the triceps brachii (p<.05). In conclusion, there was no relation between strengthening exercise and associated reaction in the upper extremities. Rather, muscle activities after exercise had a tendency to decrease relative to before the exercise. Thus, it is considered that intensive strengthening exercise contributes to improvement of functional recovery without increase in associated reaction in hemiparetic patients.

  • Objectives : The purpose of this study was to report possibility of acupuncture or moxibustion for the treatment of Parkinson's disease (PD) by reviewing literature about its effectiveness. Methods : In this review, PubMed, SCOPUS, Science Direct and CINAHL of EBSCOhost were used to search medical journals, using keywords "Parkinson's disease and acupuncture" and "Parkinson's disease and moxibustion". The search range included randomized controlled trials (RCT) about Parkinson's disease combined with another disease and other treatments with acupuncture or moxibustion. Non-randomized controlled trial (nRCT), case study, animal experiment, human experiment, review, survey, essay, letter, and protocol for review were excluded. Results : From 311 studies, 111 were selected during the title and the screening. Finally, 16 RCTs (15 for acupuncture research and one for moxibustion) were included in this review, after scanning and matching the inclusion and exclusion criteria. The number of patients varied between 5 and 88. A total of 12 studies using electroacupuncture (EA) were classified into acupuncture studies. The body acupuncture studies numbered 4, scalp acupuncture 4, body and scarp acupuncture mixed studies 4, and bee venom, ear and abdomen acupuncture were each one study. In evaluation methods, total effective rate method was used in 9 studies, the Unified Parkinson's Disease Rating Scale (UPDRS) was used in 8, and the Webster score in 2. In addition, the Berg balance scale (BBS), 30 m walking time, steps to walk 30 m, PD motor function score, and Motor Performance Series by Schoppe (MLS) method were used for evaluation. In 15 of the 16 studies, the verum acupuncture group showed significant improvement compared with the control. In 9 studies using total effective rate method, the effective rate was reported as 80.0-97.3% in verum acupuncture groups and 52.6-86.4% in controls. Conclusions : Acupuncture may be a plausible alternative method to care for the long term symptoms and treat movement impairment of Parkinson's disease. However, to confirm this result, high quality studies including randomized, placebo-controlled double-blind trials are warranted.

  • Objective : This multi-center clinical study was designed to determine the long-term results of patients who received a one-level posterior lumbar interbody fusion with expandable cage ($Tyche^{(R)}$ cage) for degenerative spinal diseases during the same period in each hospital. Methods : Fifty-seven patients with low back pain who had a one-level posterior lumbar interbody fusion using a newly designed expandable cage were enrolled in this study at five centers from June 2003 to December 2004 and followed up for 24 months. Pain improvement was checked with a Visual Analogue Scale (VAS) and their disability was evaluated with the Oswestry Disability Index. Radiographs were obtained before and after surgery. At the final follow-up, dynamic stability, quality of bone fusion, interveretebral disc height, and lumbar lordosis were assessed. In some cases, a lumbar computed tomography scan was also obtained. Results : The mean VAS score of back pain was improved from 6.44 points preoperatively to 0.44 at the final visit and the score of sciatica was reduced from 4.84 to 0.26. Also, the Oswestry Disability Index was improved from 32.62 points preoperatively to 18.25 at the final visit. The fusion rate was 92.5%. Intervertebral disc height, recorded as $9.94{\pm}2.69\;mm$ before surgery was increased to $12.23{\pm}3.31\;mm$ at postoperative 1 month and was stabilized at $11.43{\pm}2.23\;mm$ on final visit. The segmental angle of lordosis was changed significantly from $3.54{\pm}3.70^{\circ}$ before surgery to $6.37{\pm}3.97^{\circ}$ by 24 months postoperative, and total lumbar lordosis was $20.37{\pm}11.30^{\circ}$ preoperatively and $24.71{\pm}11.70^{\circ}$ at 24 months postoperative. Conclusion : There have been no special complications regarding the expandable cage during the follow-up period and the results of this study demonstrates a high fusion rate and clinical success.

  • The SPECT radiopharmaceuticals labeled with I-123 for dopamine transporter imaging have been used to measure dopamine transporters in patients with movement disorders. However, a cyclotron produced I-123 limits its availiability and ease of use as a radioisotope to be labeled with pharmaceuticals in routine clinical diagnostic procedures. Recently, new radiophannaceuticals for Tc-99m which has optimal characteristic for SPECT imaging have been developed to overcome the limits of using I-123. The purpose of this study was to compare the quality of [Tc-99m]TRODAT-1 with [I-123]IPT SPECT data and then to evaluate the usefulness of [Tc-99m]TRODAT-1 SPECT by using three noninvasive simplified quantitative methods. TRODAT-1 labeled with Tc-99m($15.93{\pm}0.82mCi$) and IPT labeled with I-123($6.60{\pm}0.11mCi$) were injected into five normal controls. Dynamic [Tc-99m]TRODAT-1 SPECT scans of brain were performed for 10 minutes each over 180 minnutes, and for 20 minutes at 4 hrs and 5 hrs. [I-123]IPT SPECT scans were performed for 5 minutes each over 120 minutes. Time activity curves were generated for the left basal ganglia(LBG), right basal ganglia(RBG), and occipital cortex(OCC). Dopamine transporter parameters were ohtained using (BG-OCC)/OCC, graphical method($R_V$), and area ratio method($R_A$). TRODAT-1 and IPT SPECT imaging showed high uptake at the level of the basal ganglia. (BG-OCC)/OCC ratios for TRODAT-1 and IPT were $0.80{\pm}0.14$, and $3.22{\pm}0.81$, $R_Vs$ were $0.62{\pm}0.12$, and $2.30{\pm}0.35$, and $R_As$ were $0.37{\pm}0.08$ and $1.73{\pm}0.31$, respectively. In conclusion, further improvement of [Tc-99m]TRODAT-1 imaging characteristics may be required to estimate the dopamine transporter concentrations in human brains although it shows clear BG localization.
