Background : The goal of this study was to establish the QA items and guidelines for preventing and improving of safety management. Therefore we investigated the nurses' recognition and knowledge of the safety and risk procedures and policies, and the agreement between the nurses beliefs on the degree of importance of those procedures and policies, with actual implementation in hospitals. Method : The subjects of this study were 201 nurses who participated in a program called continuing education for nurses, which held in December, 1993. Result: The results of this study were as follows: 1. Among 18 types of hospital risks, the items that scored highest or the need of closer attention in safety management was the needle stick, medication errors, falling, and bed sores. 2. In most questions of the 18 incidences, the nurses showed that the estimated result would have positive signs except for hospital infections, burns, and bed sores. 3. Even though the survey shows that incidences and types of occurences varies according to the person's age and the time of incident, they mostly occur between midnight to 6AM. Falls and bed sores can be seen more in the elderly. Medications errors, hospital infections and burns are frequently found between the ages of one through twenty. 4. There was a higher mean score for recognizing the importance of those items than the importance of implementing them. Conclusion : In summary, nurses did perceive the need of safety management but the hospital policy for proper safety management was not established. So we recommended that the hospital administration would undertake an early detection and proper management system for hospital precautions, based on QA items & guidelines presented in this study.

Objective: To evaluate the diagnostic accuracy of contrast-enhanced ultrasonography (CEUS) in differentiating between benign and malignant enlarged lymph nodes using meta-analysis. Materials and Methods: Pubmed, Embase, SCI and Cochrane databases were searched for studies (up to September 1, 2014) reporting the diagnostic performance of CEUS in discriminating between benign and malignant lymph nodes. Inclusion criteria were: prospective study; histopathology as the reference standard; and sufficient data to construct $2{\times}2$ contingency tables. Methodological quality was assessed using Quality Assessment of Diagnostic Accuracy Studies-2 (QUADAS-2). Patient clinical characteristics, sensitivity and specificity were extracted. The summary receiver operating characteristic curve was used to examine the accuracy of CEUS. A meta-analysis was performed to evaluate the clinical utility in identification of benign and malignant lymph nodes. Sensitivity analysis was performed after omitting outliers identified in a bivariate boxplot and publication bias was assessed with Egger testing. Results: The pooled sensitivity, specificity and AUROC were 0.92 (95%CI, 0.85-0.96), 0.91 (95%CI, 0.82-0.95) and 0.97 (95%CI, 0.95-0.98), respectively. After omitting 3 outlier studies, heterogeneity decreased. Sensitivity analysis demonstrated no disproportionate influences of individual studies. Publication bias was not significant. Conclusions: CEUS is a promising diagnostic modality in differentiating between benign and malignant lymph nodes and can potentially reduce unnecessary fine-needle aspiration biopsies of benign nodes.

Objectives : Instructional design is the systematic approach to the Analysis, Design, Development, Implementation, and Evaluation of learning materials and activities. We aimed to apply the rapid prototyping to instructional systems design (RPISD) in meridianology laboratory, a subject in which students train acupuncture to develop lesson plan. Methods : The needs of the stakeholders including client, subject matter expert and students were analyzed using the performance needs analysis model. Task analysis was implemented by observation and interview. First prototype was drafted and implemented in meridianology laboratory class once. The second prototype was modified from the first, by usability evaluation of the stakeholders. Results : The client requested an electronically documented manual to improve the quality of acupuncture training. The learner requested an extension of practice time and detailed practice guidelines. The main problems of students' performance were some cases of violation of clean needle technique, the lack of communication between the operator and recipient in direct, and lack of confidence in their own performance. Stakeholders were generally satisfied with the proposed first prototype. Second prototype of lesson plan was produced by modifying some contents. Conclusions : A lesson plan was developed by applying the systematic RPISD model. It is expected that the developed instructional design may contribute to the quality improvement of meridianology laboratory education.

Objectives This study aimed to search the Chinese literature on acupotomy for lumbar disc herniation and to analyze their methodologies. Methods Using 4 Chinese databases (CBM [www.sinomed.ac.cn], CNKI [www.cnki.net], WANFANG [www.wanfangdata.com], and WEIPU [www.cqvip.com]), we searched for clinical trials conducted in China over the past 10 years on acupotomy for lumbar disc herniation. The search terms used were "(腰椎椎間板脫出症 or 椎間板脫出症 or 椎間板脫出) and (针刀or 针刀松解术)" and we selected only meta-analyses that were published before December 2016. From among these meta-analyses, we excluded duplicates and selected the remaining 36 randomized controlled trials (RCTs) for our final analysis. Results The largest numbers of acupotomy papers were published in 2008 and 2013 (8 papers each). The average number of subjects was 120; the most common treatment method used for the control group was standard acupuncture (in 11 papers), and the most common concurrent treatment in the treatment group was massage (in 10 papers). The most common site of needle insertion was between the spinous processes, or at less than 0.5 cm on either side of the spinous processes (in 24 papers). The most common site of adhesion lysis was at the transverse process (in 24 papers). Two studies were blinded, and the mean Jadad score was 1.17. Conclusions A large number of RCTs on the use of acupotomy for lumbar disc herniation are conducted every year in China, and the procedure has been shown to be very effective, with few adverse effects. However, the average quality of the studies was not very high. Based on our study, we expect several high-quality clinical trials on acupotomy to be conducted in Korea in the future.

Knitwears it was only for the innerwear, but which has become more available for sportswear and highly valuable formal-dresses for women's apparel and is set a trend toward high value-added products worldwide. Also the industry connected knitwears is more widely applicative than woven industry and is running on the well founded basement for the small enterprises. This study notes that what problems are caused and which utilities can be expected when we design knitwears by Primavision and Texpia CAD system considered the programs for development of domestic knitwears industry. There are much various benefits for designing knitwears from CAD system as shortening working hours, convenience, accuracy, quality control and productivity. It doesn't depend on designer's technique, sense and experiences, but provides, through building the design accuracy, chance to have a precise communication with buyers to be satisfied with the multiplicity, uniqueness and high-quality resulting from reducing the mistake on the operation. But there are some problems for using CAD design system those are no selections for the form, type and thickness of the yarn. Even though it is knitted by the same gauge, the texture conditions show complete difference if the form and thickness is different with. The gauge control without regarding those ought to be improved and the yarn designing function should be appended like in a tektite design. And the CAD design system can not reflect the variables of operating knitting machine and needle. The CAD design system provides the manufacturers with merits those they can change the colors easily to select which one appeals to the customer and check the effects of producing and modeling on monitor. But, in the each producing progress, there are still problems to reduce the practical steps, so intensive care is required of each part.

This study was conducted to find out differences in the removal efficiency of particulate matter (PM) depending on the type of plants and the morphological characteristics of leaves. A total of 12 plants were used, with three plants selected for each type of leaves (big leaf, small leaf, compound leaf, needle leaf). We measured the removed amount of PM10 and PM2.5, the structure of the abaxial leaf surface, and the weight of the wax layer of each plant. Plants with the high removal efficiency of PM included Pachira aquatica Aubl., Ardisia crenata, and Dieffenbachia 'Marianne', and plants with the low removal efficiency included Nandina domestica Thunb, Schefflera arboricola, and Quercus dentata. The abaxial leaf surface having a high removal efficiency of PM had many large wrinkles, and the abaxial leaf surface having a medium removal efficiency was flat and smooth. On the other hand, there were many fine hairs on the abaxial leaf surface with a low removal efficiency. According to the plant leaf type, the PM10 removal efficiency of plants with needle leaves was about three times higher than that of other plants. In particular, the wax layer of conifers weighed 6-24 times higher than those of other plants. The stomata of conifers were evenly distributed on the adaxial and abaxial leaf surfaces; however, the stomata of Sciadopitys verticillata appeared in the form of papillae unlike general stomata. Therefore, the removal efficiency of PM varied depending on the macro-, and micro-morphological characteristics of plant leaves such as the structure of the abaxial leaf surface, and the weight of the wax layer. Based on this research, selecting plants that are effective in reducing PM in consideration of the plant type and leaf characteristics will improve indoor air quality and decrease exposure of PM to human body.

서천 추동리 문화유적내 토과목관묘에서 출토된 숯과 인근의 기와가마에서 연료로 사용되었던 나무의 숯을 채취하여 수종을 식별하고 각각의 흡습성과 가스 흡착성을 비교하였다. 총 23점의 숯 시료에 대해서 수종을 식별한 결과 토광목관묘에서 출토된 12점의 숯은 모두 활엽수 숯으로 9점이 참나무속의 상수리나무아속 계통, 3점이 팽나무속 숯인 것으로 밝혀졌다. 한편 기와가마에서 출토된 11점의 숯은 모두 침엽수로 경송류의 소나무류인 것으로 식별되었다. 출토 숯의 물리적 성질을 조사한 결과 토광목관묘의 활엽수 숯이 기와가마의 소나무류 숯보다 높은 흡습성을 나타냈으며 에틸렌 가스 흡착 시험에서도 상수리나무아속 숯이 소나무류 숯보다 높은 가스 흡착성을 보였다. 토광목관묘 유구에 활엽수 숯을 사용한 이유는 침엽수 숯에 비하여 활엽수 숯이 미세 세공이 많고 비표면적이 넓어 수분과 가스 흡착력이 우수하여 묘광 내에 보다 양질의 매장 환경을 조성할 수 있기 때문으로 판단된다. 한편, 기와가마에서 소나무류를 연료로 사용한 이유는 비중이 작아 재질이 연하여 연소가 잘되고 특히 재내에 다량의 수지(송진)를 함유하고 있어 발열량이 높고 비교적 화력 조절이 용이했기 때문으로 판단된다.

To examine the difference of health-related quality of life (QoL) of obese patients between before and after treatment of Korean traditional medicine. This study was assessed in 18 obese-women (age 29.72${\pm}$7.38) treated by acupuncture and herbal medicine using SF-36 quality of life questionnaire between January and July 2006, a 36 item instrument yielding 8 dimensions (Social functioning, Role limitation-Physical, Role limitation-Emotion, Mental health, Vitality, Bodily pain, and General health) and a total score. Their weight was measured by Inbody 3.0 (Biospace co. Korea). QoL and body composition was assessed twice at baseline (B) and 4 weeks after treatment. Auricular acupuncture and electrical needle stimulation to abdomen, thigh, and arm fat was used twice a week and complex herb formula was prescribed according to their constitution and symptoms for 4 weeks. Herb medication was taken 2 times a day. Respective variables were analyzed with Wilcoxon signed ranks test and the level set for statistical significance was p <0.05. The mean of the body weight (P=0.000;B64,68${\pm}$6.86, 4 WKs 60.47${\pm}$5.69), fat percentage (P=0.000;B33.14${\pm}$4.86, 4 WKs 30.16${\pm}$5.34), body mass index (P=0.000;B25.18${\pm}$2.44, 4 WKs 23.46${\pm}$2.09) and fat weight (P=0.000;B21.66${\pm}$5.06, 4 WKs 18.41${\pm}$4.57) of some obese patients decreased significantly between before and after treatment for 4 weeks. Physical functioning (P=0.48;B27.06${\pm}$3.17, 4 WKs 28.00${\pm}$1.71), Mental health (P=0.01 ;B18.83${\pm}$5.25, 4 WKs 22.00${\pm}$3.73), Vitality (P=0.028;B13.89${\pm}$3.03, 4 WKs 15.44${\pm}$2.53), Bodily pain (P=.0014;B8.84${\pm}$1.75, 4 WKs 10.15${\pm}$1.78), and the total scores (P=0.001;B104.99${\pm}$12.60, 4 WKs 114.58${\pm}$11.11) of SF-36 were increased significantly after treatments. These data show some differences in QoL and BMI between before and after treatment on obesity and suggest that the treatment with acupuncture and herbal medicine have a positive impact on several domains of QoL of some obese patients. Further randomized clinical trials (RCTs) including follow-up are needed to examine whether acupuncture and herb medicine have a positive effect on QoL of treatment group compared with control group.
