전기기기의 사용이 증가함에 따라 60Hz 전력선에서 발생되는 전자기장의 인체영향에 관한 관심이 고조되고 있다. 그와 더불어 60Hz 자기장에 의해 두통, 불면증 등 정신 신경 생리학적 증상을 호소하는 사람들이 증가하고 있다. 그러나 이러한 증상이 자기장 노출에 의한 것인지 심리적 요인 때문인지에 대하여 확실한 원인규명이 되어 있지 않다. 따라서 본 연구는 자기장 노출 시 생리학적 변화(심박수, 호흡수, 심박변이도, 뇌파의 알파, 베타파), 자각증상, 자기장 인지 여부를 동시에 측정하여 복합적으로 자각 증상 원인을 분석하는 연구를 수행하였다. 60Hz 12.5uT의 자기장을 일반인 군(16명)과 EHS 군(15명)을 대상으로 실제 노출 및 가상 노출을 하였다. 그 결과 알반인 군과 EHS 군 모두 60Hz 자기장 노출여부에 따른 생리학적 변화나 자각증상의 차이가 없었다. 또한 자기장 인지 정확도에서도 EHS 군이 일반인 군보다 인지를 잘한다고 볼 수 없었다. 그러므로 EHS 유발요인은 60Hz 자기장이 아니라 다른 심리적, 환경적 요인에 의한 것으로 사료된다.

This study aims to evaluate healthcare providers' satisfaction and demands pertaining to the collaborative first-stage pilot project between Korean medicine and Western medicine. This survey was conducted via electronic mail among 33 healthcare providers participating in the pilot project. Likert type 5-point scale or Likert type 7-point scale was used to evaluate each item. The response of '${\geq}4$' on the 5-point scale, and '${\geq}5$' on the 7-point scale were analyzed as positive answers. A total of 27 healthcare providers (81.8%) responded, of which 9 were western medical doctors (33.3%) and 18 were Korean medical doctors (66.7%). In respect to satisfaction of the pilot project, 88.9% gave positive responses on improved patients' convenience, 59.3% on treatment efficiency and 55.6% on diagnosis efficiency. In terms of self-evaluation on the pilot project, 70.4% gave positive answers on changes in quality of collaborative treatment, 74.1% on cooperation of results, 63.0% on cooperation of structure and 51.9% on cooperation of process. In terms of demand for collaborative treatment or the pilot project, 'standardized manual' and 'simplification of administrative procedures' showed highest demand, resulting up to 88.9%, followed by 85.2% demanding more public relations and 63.9% demanding enlargement of participating hospitals. This survey revealed that healthcare providers are generally satisfied with patients' convenience and treatment effects. Further studies are needed to develop a standardized manual, simplified administrative procedures, and expanded pilot project contents.

Objective: The purpose of this study was to examine the effect of changes in degrees of freedom of the fingers (i.e., the number of the fingers involved in tasks) on the task performance during force production and releasing task. Method: Eight right-handed young men (age: $29.63{\pm}3.02yr$, height: $1.73{\pm}0.04m$, weight: $70.25{\pm}9.05kg$) participated in this study. The subjects were required to press the transducers with three combinations of fingers, including the index-middle (IM), index-middle-ring (IMR), and index-middle-ring-little (IMRL). During the trials, they were instructed to maintain a steady-state level of both normal and tangential forces within the first 5 sec. After the first 5 sec, the subjects were instructed to release the fingers on the transducers as quickly as possible at a self-selected manner within the next 5 sec, resulting in zero force at the end. Customized MATLAB codes (MathWorks Inc., Natick, MA, USA) were written for data analysis. The following variables were quantified: 1) finger force sharing pattern, 2) root mean square error (RMSE) of force to the target force in three axes at the aiming phase, 3) the time duration of the release phase (release time), and 4) the accuracy and precision indexes of the virtual firing position. Results: The RMSE was decreased with the number of fingers increased in both normal and tangential forces at the steady-state phase. The precision index was smaller (more precise) in the IMR condition than in the IM condition, while no significant difference in the accuracy index was observed between the conditions. In addition, no significant difference in release time was found between the conditions. Conclusion: The study provides evidence that the increased number of fingers resulted in better error compensation at the aiming phase and performed a more constant shooting (i.e., smaller precision index). However, the increased number of fingers did not affect the release time, which may influence the consistency of terminal performance. Thus, the number of fingers led to positive results for the current task.

Objective: The visually impaired have limited access to health care services and related information, and thus, they can have serious hurdles against properly taking medications. Despite that it is important to improve self-care ability of the visually impaired for correct medication use, there have been few studies investigating their needs for health care services in Korea, particularly focusing on proper medication usage. This study is to explore safety-related issues regarding mediation usage among the visually impaired based on in-depth interview. We particularly focus on any obstacles for safe use of medicines including experience on medication-related adverse effects in order to provide preliminary evidence for policy measures to improve proper medication use among the visually impaired. Methods: Study sample was visually impaired individuals who resided in Seoul area and were registered in the National Association of Visually Impaired. The association helped the process of recruiting the study participants. In-depth interview for each study participants was conducted. Each interview was recorded and later converted into a written script to extract core contents for the analysis. Results: The study participants comprised of three women (42.9%) and four men (57.1%). One was in his 20's, and there were four participants in 30's and two in 40's. Fully impaired participants were majority (5 out of 7). Limitation to physical access to health care providers and health information were the key factors to hamper safe medication utilization among the study participants. Difficulty reading medication information and may take the wrong medication or incorrect doses of medication, resulting in serious consequences, including overdose or inadequate treatment of health problems. Visually impaired patients report increased anxiety related to medication management and must rely on others to obtain necessary drug information. Pharmacists have a unique opportunity to pursue accurate medication adherence in this special population. This article reviews literature illustrating how severe medication mismanagement can occur in the visually impaired elderly and presents resources and solutions for pharmacists to take a larger role in adherence management in this population. Conclusion: The visually impaired had difficulties reading medication information and identifying medicines, and took incorrect doses of medications. Public support for safe medication use and medication management among the visually impaired is necessary.

Objectives: Pregnant women and those of childbearing age are a well-known sensitive population for human mercury exposure. Therefore, this study was conducted to reveal and enrich basic information for effective risk communication to reduce the adverse health effects of mercury exposure. Methods: A self-administered questionnaire survey was conducted among 432 women aged 19-44 years, recruited conveniently from three different regions (Busan, Ulsan, and Gumi City). Questionnaires were developed by referring to the existing literature and through expert meetings. They consisted of questions on knowledge and awareness of mercury exposure risks, health information literacy, and relevant information. Results: The rank of perceived mercury health risk score was 5 out of 16 environmental risk factors, and 41.7% of participants thought that even a very little mercury could lead to an adverse health effect. Although 90.3% of participants had knowledge that childbearing age women must pay attention to fish intake, only 38.9% of participants knew the national fish intake guidelines for pregnant women. Conclusions: Although risk perception and knowledge of pregnancy-specific features of mercury were relatively high, the national fish intake guidelines were still not well recognized. It could be an effective strategy to provide evidence-based and targeted information articulated by professionals using internet based communication channels.

Background: Complementary alternative medicine (CAM) use in children with cancer is widespread. Health-care providers (HCP) need to acknowledge and address this need. This study explored and compared perspectives on CAM of HCP and parents of young patients with cancer in Indonesia. Materials and Methods: We conducted a cross-sectional study using semi-structured questionnaires in HCP and parents of childhood cancer patients at an Indonesian academic hospital. Results: A total of 351 respondents participated: 175 HCP (response rate 80%) and 176 parents (response rate 80%). Parents were more likely than HCP to think that chemotherapy can cure cancer (80% compared to 69%, P=0.013). Nearly half of all parents (46%) and HCP (45%) doubted whether CAM can cure cancer. Parents were more likely than HCP to think that CAM can be helpful in childhood cancer treatment (54% compared to 35%, P=0.003). The most recommended CAM by HCP was self-prayer (93%). Reasons for recommending CAM were: hope for improvement of the child's condition (48%), patient wants to stop treatment (42%). Most discouraged CAM by HCP was by old-smart people (70%), the reasons being: lack of evidence for usefulness (77%), lack of CAM knowledge (75%). The proportion thinking that patients were unlikely to raise the CAM topic if they perceived that doctors were skeptical was higher in parents than in HCP (52% versus 1%) (P<0.001). Most HCP (71%) and parents (77%) acknowledged that their knowledge about safety and efficacy of CAM was inadequate (P=ns). The proportion that wanted to learn or read more about CAM was higher among parents than HCP (48% compared to 31%, P=0.002). Conclusions: HCP and parents have different perspectives on CAM use in children with cancer. HCP should enhance their CAM knowledge and encourage open communication about CAM with parents. If doctors' skepticism is perceived, parents are unlikely to raise CAM as a topic.

The purpose of this study was to investigate the dietary-intake and that of health by mean of questionarie and interview for male and female old persons living in Seoul area. The contents of study included general aspects, physical status and health, nutrient intake, and food intake frequency. The results from the above survey are summarized as follows ; 1. The age group in the range of 60 to 79 years old was 71%, and the average number of family was 4.9. The educational level was 56% of elderly persons were elementary or middle school graduates . 42.8% of elderly persons had an average monthly income of \490,000 to 300,000. 2. The aged average height, weight, and physical index were 164.9cm, 55.8kg and 20.4 in male, 152.7cm, 46.0kg and 20.3 in female which were lower than the Korean average standard. (male; 167.0cm, 61.0kg, female; 156.0cm, 55.0kg) In the degree of health self-consciousness, percentage distribution of poor and very poor was 29% in male, 59% in female. Among the condition of disease, neuralgia was 23.8%, hypertension was 17.2%, diabetes was 5.4%. 3. Average daily calorie intake was $63.9{\sim}70.4%$ for male and $76.4{\sim}83.9%$ for female which were lower than the Recommended Dietary Allowances for Koreans. Protein intake was $42.9{\sim}57.3g$ (which was $72.8{\sim}82.6%$ RDA) for elderly person, the proportion of animal protein to total protein intake were $24.3{\sim}28.2%$($12.9{\sim}16.2g$). Iron, Vitamin $B_1$, $B_2$ Niacin intake exceeded the RDA, but the intake of Calcium, Vitamin C were far less than that of RDA. 4. In the correlations between nutritional intakes and environmental factors and health, economic living situations and educational level as the factors which might influence the condition of nutritional intake was significant(P<0.01). 5. Food intake frequency of meats, fishes, eggs, for average of $1{\sim}2$ days per week were $44.8{\sim}50.5%$, that of milk and milk products for scarecely week were 42.9.% Correlation of food intake frequency was divided three levels-good, fair, poor. Food intake frequency as the factors which might influence the condition of nutritional intake was significant(P<0.01). The results of the survey reveal that many of elderly show evidence of general nutrient intake deficiency, it requires first of all importance of nutrition to improve nutritional level through to promotion of elderly health.

증식치료의 이론적 배경과 기전, 시술방법, 결과 및 합병증 등에 대하여 근거-중심의 문헌 고찰을 토대로 논의하고자 한다. 증식치료는 전통적으로 건 혹은 인대 이완으로 인한 통증을 포함한 만성적인 근-골격 계 통증의 치료법 중 하나로써 증식치료제를 주사하여 염증 반응을 유도하여 인체의 정상적인 치유 기전을 자극하는 최소 침습적 주사요법이다. 증식치료제는 크게 세가지 기전에 의하여 작용하며, 가장 흔히 사용되는 증식치료제는 10~25% 포도당이다. 최근 초음파 기기의 발달과 함께 증식치료에 있어서도 유용하게 이용되고 있어 진단 뿐 아니라 초음파 중재 하 시술을 통해 효율을 높이고 합병증을 줄일 수 있게 되었다. 가장 흔한 합병증은 주사 부위의 통증으로 대개 자기한정적이고 진통제에 잘 반응한다. 그 외 합병증은 드물며 경험이 많은 임상의에 의해 시행되었을 경우 비교적 안전한 것으로 보고되고 있다. 증식치료는 근-골격 계 통증 및 관절 이완의 치료방법으로써 최근 재조명되고 있으나, 현재까지 보고된 결과들은 아직까지는 그 적응과 효과에 대한 확실한 자료가 부족한 실정이다. 이에 향후 적응이 되는 대상의 선택을 확실히 할 수 있는 신체검진 혹은 진단 기술 등에 대한 연구 혹은 주사요법과 다른 보존적 치료와의 비교 연구 등을 통하여 증식치료에 대한 근-골격 계에 있어서의 독립적이면서 효과적인 역할에 대하여 명확히 해야 할 것이다.

배경: 자발성 종격동기종(SPM)은 상대적으로 드문 양성 질환으로 어떤 유발인자나 질병 없이 젊은 성인에게서 일반적으로 나타난다. 본 연구의 목적은 더 불편한 진단절차의 필요여부를 판단하고 자발성 기종격의 진단과 치료의 기준을 확립하는데 있다. [대상 및 방법: 1997년 1월부터 2004년 6월까지 한양대학교 서울병원과 구리병원에서 18명의 환자를 대상으로 회고적인 연구를 시행했다 모든 환자들은 기흉이나 외상 또는 압력손상의 증거가 없이 종격동에 공기가 있었다. 결과: 18명의 환자들 중에서 2명의 여자 환자를 제외한 대부분은 남자 환자였다. 환자들의 평균 연령은 20.95세였으며, 표준편차는 14.3세였다. 가장 흔한 증상은 흉통, 호흡곤란, 기침이었다. 검사로는 모든 환자에게서 단순흉부 촬영이 행해졌으며, 10명에게는 흉부 단층 촬영이, 6명에게는 기관지내시경이, 3명에게는 식도 조영술이 행해졌다. 평균 재원기간은 10.9일이었다. 모든 환자들은 보전적인 방법으로 치유되었으며, 1$\∼$8년간의 추적관찰 도중 단 한차례만 재발하였다. 결론: 자발성 종격동기종(SPM)은 폐간질에서 폐포의 파열에 의해 발생하는 것으로, 폐문이나 종격동으로 공기의 박리를 유발한다. 비록 자발성 종격 동기종(SPM)이 자기 제한적인 질병이지만 다른 이차적인 질병을 감별하기 위해 단순 흥부촬영과 흉부 단층촬영을 포함한 검사는 반드시 행해져야 한다. 보다 적극적인 검사는 필요하지 않을 것으로 생각된다.
