  • This study, a quasi-experimental study using a nonequivalent control group pretest-posttest design. conducted a survey on 30 patients test group and control group of IS patients sampling an adjacent population at random - who are operated on the breast cancer and are in the A University Hospital located in Suwon, to examine into the effects of foot reflex zone massage on their pain and sleep satisfaction through the nursing interventions. It gave them a foot reflex zone massage for the total 30 minutes-basic massage 10 minutes and reflex massage 20 minutes required to alleviate their pain day in day out covering a two-month period from the first of July to the first of September 2004. for the purpose of collecting data. It launched into a two-round foot reflex zone massage at 6 and 24 hours since mastectomy through a direct visit at the hospital room to measure pain intensity, physiological index(pulse and blood pressure) and sleep satisfaction of them. The results are as follows. First, it showed that there is all the difference between pain intensity of test group and that of control group. In result, the first hypothesis, pain of test group. which measure at 6(p=.000) and 24 hours(p=.001) since mastectomies, will be bigger than that of control group, was established. Second, it showed that there is all the difference between physiological index of test group and that of control group. In result. the second hypothesis, pulse(p= .025, p= .002), systolic blood pressure(p= .004, p=.012) and diastolic blood pressure(p=.004. p= .003) of test group, which investigate at 6 and 24 hours since mastectomies, will be bigger than that of control group, was established. Third, it showed that there is a significant difference between sleep satisfaction of test group and that of control group(p=.000). In result, the fourth hypothesis, sleep satisfaction of test group. which examine in the morning after mastectomies, will be bigger than that of control group, was established. In the result. a foot reflex zone massage is seen to be effective in the pain reduction and sleep promotion of patients who are operated on breast cancer, and in providing them with more qualitative care by improving confidence between them and nurses through a physical touch. Also, it can be applied to a clinical examination through an independent nursing intervention.

  • 체외충격파치료술(Extracorporeal Shock Wave Therapy, ESWT)은 보존적인 치료가 어려운 근골격계 난치성 통증 치료 뿐 아니라 심혈관계 질환까지 적용 분야가 확대되고 있는 혁신적인 치료술이다. 본 연구에서는 국내에서 사용되는 집속형 ESWT 치료기의 성능을 결정하는 충격파 음향 출력의 분포를 조사했다. 분석에 사용된 데이터는 식약처에 등록된 30개 기술 문서를 통해 수집했다. 조사 결과, ESWT 치료기 충격파의 집속 특성은, 초점 거리가 5 mm ~ 65 mm, 초점 폭이 3 mm ~ 30 mm, 초점 깊이가 4 mm ~ 108 mm 범위에서 변화하고 있다. 충격파의 최대 양압(P+)는 7 MPa ~ 280 MPa, 초점에서 에너지 밀도 Energy Flux Density(EFD)는 0.0035 mJ/㎟ ~ 35 mJ/㎟, 펄스당 에너지(E)는 0.737 mJ ~ 80.86 mJ로 매우 넓은 범위에서 분포하고 있다. P+ 및 EFD 상관성 분석에 포함된 모든 국내산 PE 방식 제품(5개) 및 1개의 EM 방식 국산 치료기는 P+ 및 EFD가 통상적인 범위를 크게 벗어나고 있으며, 예상되는 상관성을 따르지 않고 있어, 데이터의 신뢰성을 인정하기 어려운 상태이다. 음향 출력의 값에 신뢰성을 부여하기 어려운 경우, 식약처에서 인정하는 시험 검사 기관을 통해 사후 시험 검사 및 관리가 요구된다. 충격파 음향 출력에 대한 통과 기준이 치료기의 적응증에 대한 임상 시험 결과를 근거로 설정될 수 있도록 식약처의 규정 및 가이드라인 개선이 필요하다.

  • Background: Various medical emergency situations can occur during dental practices. Cardiac arrest is known to comprise approximately 1% of emergency situation. Thus, it is necessary for dentists to be able to perform cardiopulmonary resuscitation (CPR) to increase the chance of saving patient's life in emergency situation. In this paper, we conducted a survey study to evaluate to what extent dentists actually understood CPR practice and if they had experience in handling emergency situations in practice. Method: The survey was done for members of the Korean Dental Society of Anesthesiology (KDSA), who had great interest in CPR and for whom survey-by-mail was convenient. We had selected 472 members of the KDSA with a dental license and whose office address and contact information were appropriate, and sent them a survey questionnaire by mail asking about the degree of their CPR understanding and if they had experience of handling emergency questions before. Statistical analyses -frequency analysis, chi-square test, ANOVA, and so on- were performed by use of IBM SPSS Statistics 19 for each question. Result: Among 472 people, 181 responded (38.4% response rate). Among the respondents were 134 male and 47 female dentists. Their average age was $40.4{\pm}8.4$. In terms of practice type, there were 123 private practitioners (68.0%), 20 professors (11.0%), 16 dentists-in-service (8.8%), 13 residents (specialist training) (7.2%) and 9 military doctors (5%). There were 125 dentists (69.1%) who were specialists or receiving training to be specialist, most of whom were oral surgeon (57, 31.5%) and pediatric dentists (56, 30.9%). There were 153 people (85.0%) who received CPR training before, and 65 of them (35.9%) were receiving regular training. When asked about the ratio of chest pressure vs mouth-to-mouth respiration when conducting CPR, 107 people (59.1%) answered 30:2. However, only 27.1% of them answered correctly for a question regarding CPR stages, C(Circulation)- A(Airway)- B(Breathing)- D(Defibrillation), which was defined in revised 2010 CPR practice guideline. Dentists who had experience of handling emergency situations in their practice were 119 (65.6%). The kinds of emergency situations they experienced were syncope (68, 37.6%), allergic reactions to local anesthetic (44, 24.3%), hyperventilation (43, 23.8%), seizure (25, 13.8%), hypoglycemia (15, 8.3%), breathing difficulty (14, 7.8%), cardiac arrest (11, 6.1%), airway obstruction (6, 3.3%), intake of foreign material and angina pectoris (4, 2.2%), in order of frequency. Most respondents answered that they handled the situation appropriately under the given emergency situation. In terms of emergency equipment they had blood pressure device (70.2%), pulse oximetry (69.6%), Bag-Valve-Mask (56.9%), emergency medicine (41.4%), intubation kit (29.8%), automated external defibrillator (23.2%), suction kit (19.3%) and 12 people (6.6%) did not have any equipment. In terms of confidence in handling emergency situation, with 1-10 point scale, their response was $4.86{\pm}2.41$ points. The average point of those who received regular training was $5.92{\pm}2.20$, while those who did not was $4.29{\pm}2.29$ points (P<0.001) Conclusion: The result showed they had good knowledge of CPR but the information they had was not up-to-date. Also, they were frequently exposed to the risk of emergency situation during their dental practice but the level of confidence in handling the emergency situation was intermediate. Therefore, regular training of CPR to prepare them for handling emergency situation is deemed necessary.

  • 심폐소생술 지침은 과거에 미국심장학회 지침과 유럽소생학회 지침으로 크게 양분되어 있었으나, 2000년 8월에 국제심폐소생술 위원회에 의한 공동 지침으로 ‘심폐소생술과 응급심장 처치에 관한 지침 2000’이 완성되었다. 현재까지 심폐소생술로써 환자의 생존율에 괄목할 만한 향상이 없으므로 보다 새로운 지식으로써 적절히 임상에 적용하는 것이 최선의 방법이라 할 수 있다. 새 지침의 특징은 알고리듬의 단순화와 과학적인 결과를 바탕으로 하였으며,성인 심정지 환자의 기본소생처치에서 심장 마사지 : 인공 호흡을 15 : 2로 통일하고 일반인에게는 경동맥 촉지법과 하임리히법을 가르치지 않는다는 것이다. 흡입 산소농도에 따라 호흡 흡입량의 차이를 두었으며, 기관 삽관의 튜브 크기를 8.0mm로 통일하였고, 심실빈맥/심실세동의 알고리듬에서 epinephrine대신에 vasopressin을 사용할 수 있게 하였으며, 자동 제세동기의 사용을 권장하였다. 또 급성 관상동맥 증후군에서는 병원 도착 전에 심전도를 중요시하고 혈전용해제를 조기에 사용할 수 있게 하였으며 급성 허혈성 뇌졸중에서도 병원 도착 전에 적절한 평가와 빠른 혈전용해제 사용이 추가되었다.

  • The objectives of this study were to characterize the health status, the requirement of home nursing care, and dependency of daily life of the elderly so that the result could be used to provide basic data necessary for establishing home nursing care practices. The study subjects were 249 elders over 65 years old who resided at home in low income areas of three districts in Pusan. The field survey was conducted from December 27, 1993 through January 27, 1994, with a structured questionnaire. Statistical analysis was done by X²-test and Student's T-test using SPSS/PC/sup +/ program. The result were as follows; 1. Alcohol drinking rate was 50.0% for men and 27.7% for women, and cigarette smoking rate was 77.8% for men and 27.1% for women. 92.9% of elders aged 65-75 exercised regularly as compared to 81.9% of elders aged 75 and over(p<0.05). 2. 63.9% of male and 85.9% of female elders had chronic diseases showing singnificant differences(p<0.01), and both sexes had 1.7 kinds of chronic diseases in average; musculoskeletal diseases were the most common in 25.7%, while 6.8% of the elderly had cardiovascular diseases. 3. Partially movable elderly was 6.9% for men and 6.8% for woman, showing 47.1% of causes being cerebrovascular accidents. 4. The home nursing requirement was the highest for medication(66.3%), intramuscular injection(53.8%), and measurement of blood pressure·body·temperature·pulse rate(47.0%). 5. Among Physical Activities of Daily Life, bathing(10.4%) and movement(4.0%) showed high dependency rates, and among Instrumental Activities of Daily Life, phone calling(25.3%), shopping(24.5%), going out by bus(22.5%) showed high dependency rates. 6. For five categories of home nursing showing high requirements such as physical health examination, blood pressure·temperature·pulas rate measurements, medication, and intravascular injection, the requirements were different by age groups, education, and marital status(p<0.05).

  • This study has been carried out to verify curative effect of lavender and lawn, a green space composition factor. Thus, the physiological index value of blood pressure, heart rate and salivary amylase were measured with object of 16 women in their 20~30s for stress relaxation effect at lavender garden and lawn square, and impression assessment upon SD method as for psychological value was performed in this study. And a survey was conducted on necessity and reason of urban green space with object of 345 men and women urban workers. As a result of variance analysis between groups and multi test of Turkey upon object place, the blood pressure was lowered the same at lavender garden and lawn square, and especially, high blood pressure was greatly lowered to 30 mmHG at lavender garden. On the other hand, low blood pressure group showed the tendency of a little increasing at the same places. And for the pulse, there was difference between high blood pressure group and normal group at the same places. To conclude, at lavender garden and lawn square the blood pressure was made to be lowered when it's high, and when it's low, the effect of returning to sound status, the function of increasing, was verified. In case of impression assessment upon SD method, the lawn square was assessed as resting place and lavender garden diversional place. And over 90% of urban workers responded to the green space's necessity and curative effect, diversion and resting place were adopted for the reason in high-ranking items. As above the green space pattern that urban workers require and curative effect of lavender garden and lawn square were verified. Therefore, the functional green space plan is required, which curative effect, diversion and resting place are considered, for the future green space plan design.

  • Atmospheric propagation effects at millimeter wavelengths can significantly alter the phases of radio signals and reduce the coherence time, putting tight constraints on high frequency Very Long Baseline Interferometry (VLBI) observations. In previous works it has been shown that non-dispersive (e.g. tropospheric) effects can be calibrated with the frequency phase transfer (FPT) technique. The coherence time can thus be significantly extended. Ionospheric effects, which can still be significant, remain however uncalibrated after FPT, as well as the instrumental effects. In this work, we implement a further phase transfer between two FPT residuals (i.e. so-called FPT2) to calibrate the ionospheric effects based on their frequency dependence. We show that after FPT2, the coherence time at 3 mm can be further extended beyond 8 hours, and the residual phase errors can be sufficiently canceled by applying the calibration of another source, which can have a large angular separation from the target (> $20{\circ}$). Calibrations for all-sky distributed sources with a few calibrators are also possible after FPT2. One of the strengths and uniqueness of this calibration strategy is the suitability for high frequency all-sky survey observations including very weak sources. We discuss the introduction of a pulse calibration system in the future to calibrate the remaining instrumental effects and allowing the possibility of imaging the source structure at high frequencies with FPT2, where all phases are fully calibrated without involving any sources other than the target itself.

  • Objectives: The purpose was to study the market of traditional Korean medical devices and survey, list and number medical devices in traditional Korean medical clinics. Methods: we researched in three ways. 1. We investigated the list of devices regarded as traditional Korean medical devices in 'Report on production, export, and import of medical devices.' 2. We investigated the statistics of medical devices equipped in traditional Korean medical clinics through the website of the Health Insurance Review & Assessment Service. 3. We surveyed medical devices in traditional Korean medical clinics by mail. Results: 1. We could not directly investigate the market for traditional Korean medical devices because they were not categorized as such ('traditional Korean medical devices'). 2. The number of medical devices in traditional Korean medical clinics has increased alongside the increase of traditional Korean medical clinics. 3. Traditional Korean medical clinics hold over 64,962 medical devices and have below 50 percent of traditional Korean medical diagnosis devices. 4. Meridian function testing machines, pulse diagnosis devices, and yangdorak showed ranking of equipment-ratio equal to ranking of insurance fees. Conclusions: Traditional Korean medical device regulations should be enacted following definitive and concrete Korean traditional medical concepts by the Korean traditional medical society.
