This study analyzed the services as operated by the Child Health Telephone Service Center. The Center is a toll free service operated as part of the community services of the Korean Academic Society of Child Health Nursing. The aim of the study was to describe the concerns of child caregivers regarding child health care as discussed during telephone counseling. Specific objectives were as follows: 1. To analyze the activities of the Center. 2. To describe the characteristics of caregivers who made phone calls for counseling services and also the characteristics of their children. 3. To analyze the content of the counseling sessions. 4. To analyze counseling content according to the characteristics of the caregivers and their children. Data used for the study were obtained from the counseling records for the period from Sept. to Dec. 1999, as kept by the three counselors at the Center. The total number of calls was 8,261 and that consisted of 15,150 questions. The total questions were merged into 13,236 by eliminating those questions which overlapped or were of similar content. The final 13,236 questions were used for the final analyses. Almost of the callers (98.4％) were mothers. Among them 89.6％ were between 25 and 35 years of age. Geographical distribution of the callers covered the whole nation. The largest numbers who made the calls were from the Seoul metropolitan area (36％), followed by 28％ from Kyung Gi Province, and 20％ were from the Kyung Sang area. Among 8,261 callers, 72.8％ were first users. Sex of the babies and children in question for counseling was about even for males and females and ages ranged from one month to six years. The largest group (62.5％) was the less than six month age group. The finalized 13,236 questions/problems were categorized into 11 problem areas. They were in order of frequency, physical problems, feedings and nutrient concerns, information on child rearing, growth and development, guidance on utilization of child care facilities, elimination problems, sleeping concerns, immunization related concerns, behavior problems, injury and accidents, and safety measures. The most frequent problems for counseling were physical signs and symptoms (27.3％), followed by feeding and nutrients, information on child rearing, and growth and development. Of physical problems, abnormal gastrointestinal signs and symptoms were the most frequent concern and skin problems were next at 25％ and 23.3％ respectively. Loose bowels, vomiting and constipation were the most frequent gastrointestinal problems. Atopic dermatitis had the highest frequency at 53.3％ with diaper rash being the second highest among the skin problems. About 80％ of the growth and developmental category were physical development concerns related to physiological, body growth, and motor and sensory development. This study constitutes the activity report for the first year of the Center. The findings correspond with literature reports on child health problems and parents educational needs. One recommendation from this study is that since the services of the Center are carried out only by telephone, the psychology of the counselees and the counselor relationship must be considered for better services.

Radiation synovectomy is one of the most useful methods for treating patients with refractory synovitis because of its convenience, long-term effects, repeatability and the avoidance of surgery. In this study, we investigated the toxicity, stability and biodistribution of a rhenium-188 ($^{188}$Re)-tin colloid to evaluate its suitability as a synovectomy agent. Twenty four hours after injecting the $^{188}$Re-tin colloids (74 KBq/0.1 mL) into the tail vein of ICR mice, most of the $^{188}$Retin colloidal particles was found in the lungs. In addition, there were no particle size changes at either room temperature or at $37^{\circ}C$ after injecting the $^{188}$Re-tin colloids in human plasma and synovial fluid. In vitro stability tests showed that the $^{188}$Re-tin colloid remained in a colloidal form without a critical size variation over a 2-day period. We investigated the leakage of $^{188}$Retin colloids from the intraarticular injection site with gamma counting in New Zealand white rabbits. The $^{188}$Re-tin colloids (55.5 MBq/0.15 mL) were injected at the cavum articular and the mean retention percentage of the $^{188}$Re-tin colloid was 98.7% for 1 day at the injection site, which suggests that there was neither change in the particle size nor leakage at the injection sites. In the biodistribution study with the SD rats, the liver showed the highest radioactivity (0.0427% ID/organ) except for the injected knees (99.49%). In the SD rats, mild toxicities including the skin or a synovium inflammation were observed as a result of a radioactivity of 15 mCi/kg at the intraarticular injection site. However, there was no systemic toxicity. In the Ovalbumin (OVA)-induced arthritic rabbits, the $^{188}$Re-tin colloid improved the macroscopic, the histological score and reduced the knee joint diameter when compared to the arthritic control. In conclusion, a $^{188}$Re-tin-colloid is considered as a strong candidate for radiation synovectomy with a superior efficacy and safety.

The occupational health nursing guideline for primary care was developed by the Korean Academic Society of occupational health nursing and the organization for occupational health nurses (currently known as the Korean Association of Occupational Health Nurses) in 1993. Since then, there have been many changes in the health care environment and job performance of occupational health nurses. Appropriate revisions are necessary of the guidelinea based on this background. The purpose of this study was to describe the use of the occupational health nursing guideline for primary care and to analyze the characteristics of primary care activities by occupational health nurses. The questionnaire was mailed to 150 occupational health nurses(OHNs) with the response rate of 64%. The results can be summarized as follows; 1. 65.6% of OHNs have been using the guideline for primary care and 75.9% of them agreed that the guideline was be helpful for their job. 2. Common symptom care, emergency care and chronic illness care were more frequently implemented than occupational disease care by OHNs. In manufacturing industries, emergency care was more frequently implemented than chronic illness care in contrast to the service industries. 3. Most frequent common symptoms treated by OHNs were indigestion, diarrhea, abdominal pain, headache, and coughing. In the case of chronic illness, OHNs more frequently treated diseases of the gastro-intestinal system, skin and sensory organs, and the respiratory system. Emergency care for bruises, burn, and abrasions was more frequently provided. VDT syndrome was the most common occupational disease cared by OHNs in manufacturing and service industries. 4. OHNs prescribed the medicine for external application more frequently than internal medicine. Remedy for colds, analgesics, vitamins, and digestives were more frequently used. From these results, we suggest that the guideline should be revised to emphasize the activities consisting problem finding such as health assessment, physical examinations, monitoring and screening, and to renew the drug list in the range of over- the counter medication (OTC). In the future, the guideline will include the strategies for the role as the case manager.

본 연구는 방사성 동위원소인 ^99mTc, ¹⁸F가 주입된 환자에게서 나오는 감마선이 안정실 벽면 등의 높은 원자번호로 되어있는 물질과 밀착되어 증가하는 산란선으로 인한 표면 선량 변화를 알아보고자 하였다. NEMA 팬텀에 ^99mTc과 ¹⁸F을 각각 20, 10 mCi를 주입하여 준비한 뒤 지표면과 1 m 높이에 팬텀을 위치시키고 주위가 빈 공간인 경우와 벽면으로부터 0, 5, 10 cm 거리에 팬텀을 위치시키고 벽면과 마주 보는 팬텀의 동일한 위치에 25개의 OSLD NanoDot을 부착시켜 60분간 표면 선량을 측정하였다. 실험의 재현성을 위하여 각 5회 반복 실험하였으며, 유의성 검정을 위하여 일원 배치 분산분석 (one way Analysis of Variance; ANOVA)을 시행하고 사후 검정으로 Tukey를 사용하였다. 연구결과 주위가 빈 공간인 경우와 0, 5, 10 cm 였을 때 ^99mTc에서는 각각 220.268, 287.121, 243.957, 226.272 mGy의 표면 선량이 측정되었으며, ¹⁸F에서는 각각 637.111, 724.469, 657.107, 640.365 mGy로 측정되었다. 환자가 대기하는 동안 위치에 따른 표면 선량 변화를 줄이기 위해 환자와 밀착되는 땅바닥이나 벽면과의 거리를 10 cm 이상의 거리를 두거나, 에어매트리스 등을 설치하여 산란선을 최대한 예방하는 것이 필요하며, 향후 환자 대기실 및 안정실 등의 구조 설정 시에 벽면 등으로 인한 산란선을 고려해야 하며, 검사 이외에 외부피폭을 감소시킬 수 있다는 점을 증명한 것에 이 연구의 의의가 있다.
