Purpose: This study explores school nurses' emergency care experiences and their needs for systemic institutional support. Methods: Data were collected in 2016 from the interviews with five focus groups comprising thirty school nurses. Qualitative content analysis was then performed using the collected data. Results: The study found that school nurses were vulnerable to over-reaction in uncertain situations as the school's sole health service provider. The study's findings are divided into ten categories. 1) Major obstacles to overcome as the sole health service provider, 2) Assessing an uncertain situation and making appropriate decisions, 3) Providing limited first aid while maintaining control over the situation, 4) Referring or transferring a student to a hospital that creates tensions and raises cost, 5) Becoming an advocate for information disclosure and treatment, 6) Ensuring follow-up actions and proper transfer of responsibility, 7) Making preparations for future emergency, 8) Responding to conflicts arising from over-reaction as a safeguard and professional expertise, 9) Need for the development of standardized manual for school emergency care, 10) Need for practical case-based training. Conclusion: The findings of this study should contribute to the development of the programs aimed at improving school emergency care and the professional competence of school nurse.

Age and growth of red tongue sole (Cynoglossus joyneri), were studied using samples from the coastal waters off Yeosu, Korea, from January to December, 2001. Sagittal otoliths had relatively clear annuli. Marginal index of otolith dropped sharhly in August suggesting that each annulus was formed once a year In August. Monthly changes in the gonadosomatic index indicated that spawning peaked between July and September. The oldest fish observed in this study was 4 years old for both of females and males. Relationships between the otolith radius (R) and total length (L) were: L=14.1R-0.098 for females, and L=11.9R+1.83 for males. Relationships between total length and body weight $(W)\;were:\;W=0.0021L^{3.24}\;for\;females,\;and\;W=0.0014L^{3.39}$ for males. Growth in length of the fish was expressed by the von Bertalanffy's growth equation as:$L_{t}=29.06\;(1-e^{-0.19(t+2.40)})\;for\;females\;and\;L_{t}=27.44 (1-e^{-0.17(t+2.84)})$ for males.

Using crude soybean oil as the sole carbon source, the lincomycin production from Streptomyces lincolnensis LC 345 was investigated in the air lift bioreactor. When 30 g/L of crude soybean oil was used, the maximum lincomycin concentration reached 0.89 g/L, after 5 days of culture. When CSL concentration was increased from 10 to 30 g/L, Lincomycin concentration was increased from 0.6 to 1.2. On the other hand, when CSL concentration was increased from 40 to 60 g/L, it was decreased from 1.15 to 0.7 g/L. Using these results, fed batch cultures for comparing the use of crude soybean oil and glucose as a conventional carbon source were carried out in a 5 L air lift bioreactor. When crude soybean oil was used as the sole carbon source, the maximum lincomycin concentration was 2.0 g/L, which was about 2.0 fold higher than that of glucose medium after 7 day of culture. The product yield from olive oil was 0.042 g/g consumed carbon source, which was about 3.8 fold higher than that of glucose.

Purpose: Simple part or equipment is necessary TRA(Technology Readiness Assessment) or MRA(Manufacturing Readiness Assessment). But sole maturity like TRA, MRA has limit complex systems or SoS(System of System). Especially complex weapon system need from the System Maturity Point of view. This research shows necessity of SRA(System Readiness Assessment). Methods: In case of complex systems, it is essential to SRA(System Readiness Assessment). For the purpose of calculating SRL(System Readiness Level), TRL and IRL must be calculated. And then SRL can obtain know from equation of TRL and IRL. To prove SRA effectiveness, it is calculated SRL of JTDLS(Joint Tactical DataLink System) programs. Results: SRA procedure is proposed and case study shows as examples of JTDLS programs. Although result of TRA is TRL6, result of SRA is not 0.6. From this research, we can know necessity of SRA. Especially complex systems or SoS(System of System) is essential to SRA. Conclusion: SRA(System Readiness Assessment) is required to overcome limitation of sole maturity and to achieve a successful acquisition of high quality weapon system. This research intended to suggest SRA procedure and case study in complex defense system.

Purpose: The purpose of this study was to investigate tactile sense perception of the lower extremities according to physical function in children with spastic cerebral palsy. Methods: This study was conducted on 15 children diagnosed with spastic cerebral palsy. Physical function measurement items included dynamic balance ability, gross motor function level, and lower extremity ankle spasticity. The lower extremity tactile sensation uses a monofilament to measure the sole of the first metatarsal head, the sole of the fifth metatarsal head, the heel, the anterior part of the shin midway between the patella and the ankle joint, the kneecap, the upper anterior iliac spine, and the knee. A total of six measurements were taken in the mid-femoral region of the bone. Spearman correlation analysis was performed to determine the degree of body function and lower extremity tactile perception. Results: As the physical function of children with spastic cerebral palsy deteriorated, there was a decrease in tactile sensation in the thigh area corresponding to the proximal lower extremity. (p <.05). Conclusion: Children with spastic cerebral palsy and poor physical function have sensory loss not only in the distal part but also in the proximal part, so a treatment approach that recognizes and improves it is necessary.

Objective: The purpose of the study was to investigate the effect of shoe sole deformation on the muscle activity and balance of the lower extremities when standing on one foot. Design: Crossed-control group study Methods: A total of 18 healthy adults participated in this study. 9 participants with normal shoe and 9 participants with deformed in shoe out-soles (wear shoes) were included. Muscle activity of the tibialis anterior, fibularis longus and gluteus medius during one leg standing was measured using a electromyography. A balance board was used to evaluate balance ability when standing on one leg. The balance ability when standing on one leg was measured by the sway speed and distance of the center of gravity. Results: Muscle activity of the tibialis anterior, fibularis longus and gluteus medius was no significant difference between groups (P > 0.05). Balance ability when standing on one leg was significantly different from the group wearing normal shoes in all variables related to the sway distance and sway speed of the center of gravity. Conclusions: Through this study, the wear of the outer sole of the shoe indirectly confirmed the effect on the wearer's lower extremity muscle activity and balance ability when standing on one foot. These results of this study are expected to be used as basic data for future studies on shoe wear, lower extremity muscle activity and balance ability.

배경: 다한증에 대한 흉부교감신경절제술은 흉강경기구 및 수술술기 발달로 효과적인 치료방법으로 인식되고 있으나 보상성 다한증으로 그 만족도가 떨어지고 있다. 따라서 저자들은 수술결과 및 보상성 다한증을 분석하고자 하였으며 수술전후 손과 발의 온도 차이 그리고 상지와 하지의 혈류량을 측정하였다. 대상 및 방법: 1995년 12월부터 1998년 7월까지 강남성모병원에서 총 47명의 다한증환자를 흉강경하에 교감신경절제술을 시행하였다. 수술전후로 손가락 및 발가락에서 온도변화를 측정하였고, 혈류량 측정은 도플러 초음파검사로 손가락동맥, 요골동맥, 그리고 족배동맥에서 측정하였다. 결과: 수술사망은 없었으며, 기흉 7건, 재발 3건, 안검하수 1건등의 합병증이 있었다. 보상성 다한증은 수술한 환자의 95%에서 있었으며 이중 5명이 수술을 후회하였다. 족부 다한증은 흉부교감신경절제술후 46%에서 향상되었고, 수술전후 온도변화는 우측 손에서 1$^{\circ}C$, 좌측 손에서 1.9$^{\circ}C$였고 통계적으로 의미있게 증가하였다. 그러나 족부 다한증에서는 의미있는 온도차이가 없었다. 혈류량은 손에서 의미있게 증가하였으나 발에서는 차이가 없었다. 결론: 다한증의 흉부 교감신경절제술은 안전하고 효과적인 치료이지만 그 만족도는 보상성 다한증에 의해 감소하고 있으므로 수술전에 보상성 다한증에 대하여 충분히 설명하는 것이 중요하다. 족부 다한증은 생리적 변화에 의한 것이라기 보다는 정신적 안정에 의한 것으로 보인다.
