There are still occurring aviation accidents in spite of great preventing efforts all over the world. This paper contains some methods to prevent aircrafts deficiencies and accidents. First part of this paper refers to the background of those aviation deficiencies on mechanical, human and environment structures which influence directly to the air accidents and general survey on various theories of the aircraft's systems. On the way we discussed the general situations of the air tool's deficiencies which cause tragic accidents to the human lives and assets. After analysis on the situations we suggest the new systems which would forecast more detail accuracies concerned air elements for the safety flying. Then we introduce the following new systems resulting from the forecasting which can solve problems on aircraft deficiencies and complex interrelationships among air accidental factors. To simplify the complex systems, we needed to build the mechanical and organizational database for maintaining the procedures of the past troubleshooting on the major parts preventing deficiencies of those mechanical units. These suggested systems will contribute a great deal of aids, the maintenance credibility and air safety for the air operations and all customers in the world. Avoiding the past troubleshooting from just by using simple systems which can forecast main causes of the units and parts of the crafts, this system will be able to provide excellent management tools for the promoting aviational industries. The comfortable and convenient air operations are very valuable works, and the scientific method and detail maintenance will improve our daily air life by minimizing accidents. Adapting these developing systems, for the forecasting aircraft deficiencies and accidents can be integrated with the other aircraft management systems to promote more air safety in the world. This study is focused to eliminating aircraft accidents through forecasting deficiency symptom procedures by relational coordinations among all of the systems. Futhermore we need continuously detailed analysis and study for eliminating air accidents all together those who work in those fields.

The aim of this study was to suggest the future direction of diagnostic and evaluative pattern identification questionnaire (PIQ) by reviewing the state of development and utilization of PIQ according to Korean classification of disease-U (KCD-U). We surveyed the database of OASIS, NDSL, KISS, DBPIA, and Pub-med to know the kinds of developed and developing PIQ of Korean medicine. We used 'Pattern Identification' and 'Questionnaire' to find suitable papers. The inclusion criteria met 47 cases. The number of PIQ before 2000yrs, between 2001 to 2005, 2006-2010, 2011-2015 were 2, 5, 18, 22cases. The number of PIQ belonged to the disease of Korean medicine, the pathological symptom of korean medicine, the Sasang constitutional pattern identification and etc according to KCD-U were 20(42.6%), 8(17%), 9(19.1%) and 10(21.3%). Twenties among forty seven PIQ were validated, and the rest of them were not validated. The distribution of the numbers of PIQ were significantly different according to KCD-U (p=0.003). The direction of Utilization of PIQ was 36 questionnaires in diagnosing PI, 14 cases in evaluating health state, 4cases in evaluating effects of a treatment and 8 ones in diagnosing Sasang constitutional types. This study reveals the status on validated and non-validated PIQ of Korean medicine and suggests the basic information for the direction of developing PIQ in the future.

Objectives Through the clinical records of Seungjeongwon Ilgi, we reviewed the usage of Bi-Jeung to know the concept of the word and studied therapeutic strategies for managing Bi-Jeung. Methods We investigated the clinical records of the mid-Chosun dynasty containing the key word "Bi" from electronic database (Seungjeongwon Ilgi). Results Of 4,039 records, 249 articles thought to have medicinal value were lastly selected. We subdivided the cases into 13 categories according to time, the connection of contents and the change of associated symptoms. "Bi" was not used alone but used in combination with body parts or other symptoms. Etiological causes of "Bi" involved dampness, phlegm, fire, heat and qi disorders. We suggested that "Bi" of the mid-Chosun dynasty meant a symptom group mainly of sensory impairment and additionally pain or motor disturbance. Among the 22 herbal medicine formulas used, 15 were based on internal medical pattern identifications and 7 were symptomatic treatments. Acupuncture and moxibustion therapy were primarily applied to adjacent acupoints. In addition, External therapies were used together, such as washing therapy, plaster therapy, cupping therapy and thermotherapy. Conclusions "Bi" principally indicated sensory impairment on limbs and the main etiological cause was considered to be dampness. Herbal medicine, acupuncture, moxibustion and external therapies were used to cure Bi-Jeung.

Background: Magnetic resonance (MR) images are useful for diagnosing myopathy. The purpose of this study was to determine the usefulness of lower-limb MR images in Korean patients with distal myopathy. Methods: We reviewed medical records in the myopathy database from January 2002 to October 2016. We selected 21 patients from 91 unrelated families with distal myopathy: four with GNE myopathy, 11 with dysferlinopathy, and six with ADSSL1 myopathy. Results: Ten (48%) of the 21 patients were men. The ages of the participants at symptom onset and imaging were $19.2{\pm}9.5$ and $30.4{\pm}9.0$ years (mean${\pm}$standard deviation), respectively. Their grade on the modified Gardner-Medwin and Walton grade was $3.3{\pm}1.7$. The strength grade of the knee extensors was not correlated with the Mercuri scale for the quadriceps (r = -0.247, p = 0.115). However, the Medical Research Council grades of the knee flexors, ankle dorsiflexors, and ankle plantar flexors were significantly correlated with the Mercuri scale ratings of the knee flexors (r = -0.497, p = 0.001), tibialis anterior (r = -0.727, p < 0.001), and ankle plantar flexors (r = -0.620, p < 0.001), respectively. T1-weighted MR images showed characteristic fatty replacement patterns that were consistent with the causative genes. Unsupervised hierarchical clustering of the Mercuri scale showed that the main factors contributing to the dichotomy were the causative gene and the clinical severity. Conclusions: This study is the first to reveal the usefulness of lower-limb MR images in the differential diagnosis of distal myopathy in Korea.

Objective: The purpose of this study was to review Chinese clinical studies of the treatment of gastroesophageal reflux disease (GERD) with herbal medicine including Pinellia ternata. Methods: We searched the China National Knowledge Infrastructure (CNKI) database for clinical studies on herbal treatments including Pinellia ternata for GERD, from January 1st, 2015 to September 30th, 2019. We evaluated the risk of bias using Cochrane's risk of bias to confirm the quality of the 37 selected documents. Results: The 37 papers included high-dose and middle-dose Pinellia ternata groups. The outcome measures included treatment effectiveness rate, symptom comparisons, and endoscopy effectiveness rates or scores. In both groups, most studies showed significant improvement in the treatment group compared with the control group. The meta-analysis revealed a higher treatment effectiveness rate and a lower recurrence rate in the treatment group than in the control group. Conclusions: Comparing the treatment effect between the two groups was difficult due to the low quality of most studies. However, the results suggest that herbal remedies including Pinellia ternata showed statistically significant improvement in GERD compared to control groups.

In this paper, we propose a crucial issue to require further management plan for Korean hospital nurses in burnout during COVID-19 pandemic. The purpose of this study was to conduct a systematic review of factors related to hospital nurses in burnout for the COVID-19 outbreak. Appropriate studies in the recent three years were selected from database. To perform a systematic review, the databases of RISS, KISS, DBPIA, and Kyobo scholar were searched using the key words, 'nurse in burnout' or 'burnout for nurse'. Fifty-five references were checked, but only seven studies were decided inclusion criteria to review. It was founded that Korean hospital nurses felt moderate or higher burnout level for COVID-19 pandemic. We were confirmed that related factors of hospital nurses in burnout were personal characteristics, physical symptom, depression, compassion satisfaction, compassion fatigue, and resilience, and occupational characteristics, shift work and job stress. It may be necessary to provide regulating programs for hospital nurses in burnout and to set up a policy and guidelines so as to reduce burnout of nurses working.

Objective : To investigate syndrome identification, herbal prescriptions, acupuncture point and other treatment, this study systematically reviewed case studies on Korean medicine (KM) treatment for urticaria. Method : Literature searches were performed on four Korean database; OASIS, RISS, KTKP and NDSL. Studies published before December 2022 were categorized and analyzed according to the herbal prescriptions. Results : Thirty-three studies including 16 case series and 17 single case reports were included in our review and the total number of patients was 523. Ancient prescriptions (古方) were used in 7 studies and prescriptions of Sasang constitutions were used in 8 studies and 18 studies used prescriptions of posterity (後世方). Wind-Heat (風熱) and syndrome identifications associated with digestive function were used frequently. Nineteen studies used acupuncture combined with herbal medicine and mainly used acupoints were ST36 (足三里), LI4 (合谷), LI11 (曲池), LR3 (太衝), SP6 (三陰交), CV12 (中脘), SP10 (血海). External herbal medicine was used in only 3 studies. Conclusion : To increase the cure rate of KM, various prescriptions should be used according to the symptom and stage of urticaria. Diversification of herbal formulations and the development of new external medicines are also necessary to conduct additional clinical studies with a high level of evidence.

Purpose: Since technology-based interventions can facilitate convenient access to healthcare for women with breast cancer, it is crucial to understand innovative approaches to maintaining the effectiveness of these interventions. Therefore, we conducted a systematic review of technology-based self-management interventions for women with breast cancer in six countries. We analyzed the characteristics of these interventions and examined their diverse health outcomes. Methods: Six databases were systematically searched to extract research articles using the keywords "breast cancer," "technology," and "self-management." The search was carried out up until June 12, 2023. From the 1,288 studies retrieved from the database search, 10 eligible papers were identified based on inclusion/exclusion criteria. Two authors independently extracted and compared the data from these articles, resolving any discrepancies through discussion. Results: Most of the 10 studies utilized web- or mobile-based technology, and one used artificial intelligence-based technology. Among the 12 health-related outcome variables, quality of life and symptom distress were the most frequently mentioned, appearing in six articles. Furthermore, an analysis of the intervention programs revealed a variety of common constructs and the involvement of managers in the self-management intervention. Conclusion: Incorporating key components such as self-management planning, diary keeping, and communication support in technology-based interventions could significantly improve the self-management process for breast cancer survivors. The practical application of technology has the potential to empower women diagnosed with breast cancer and improve their overall quality of life, by providing timely and sustainable interventions, and by leveraging available resources and tools.

Objectives: Outbreaks of pneumonia caused by Mycoplasma pneumoniae (MP) occur every 3-4 years in Korea, most recently in 2011. The aim of our study was to determine the optimal time to perform indirect particle agglutination antibody assays to improve early diagnosis of MP pneumonia in children. Methods: A database of 206 pediatric patients treated for pneumonia at the Hanyang University Hospital from June to October 2011 was analyzed retrospectively for demographic characteristics and laboratory test results. Results: Among the 206 patients treated for pneumonia during the study period, there were 160 children (mean age, 5.44 years) diagnosed with MP pneumonia, who were studied further. The mean age of these MP pneumonia patients was 5.44 years. Antibody titers increased with increasing time between symptom onset and the collection of serum collection: MP titers were <1:640 for sera collected after 5.44 days and titers ${\geq}1:640$ for those collected after 8.58 days; P<0.001). Antibody titers were considered positive when they reached ${\geq}1:640$. In 42 MP pneumonia patients in whom there was a four-fold or greater increase in titer between successive serum samples, the optimal cut-off time-point for distinguishing between the initial and second titer groups was 7.5 days after the onset of symptoms (sensitivity, 90.5%; specificity, 92.9%). Conclusions: Negative MP antibody titers earlier than 8 days after the onset of symptoms in children with pneumonia may require repeating to confirm the diagnosis. This finding could optimize diagnosis and result in better therapeutic outcomes of MP pneumonia in children.
