Objectives This research was proposed to present clinical practice guideline (CPG) for Taeyangin Disease of Sasang Constitutional Medicine (SCM). This CPG was developed by the national-wide experts committee consisting of SCM professors. Methods This guideline was performed that search and collection of literature related SCM such as "Dongeuisusebowon", textbook of SCM, clinical guidebook of SCM and fundamental research to standardize diagnosis of Sasang Constitutional Medicine. Journal search related clinical trial or human complementary medicine of SCM was performed domestic and overseas. Finally, 1 article was selected and included in CPG for Taeyangin disease. Results & Conclusions The CPG of Taeyangin disease include classification, definition and standard symptoms of each pattern. Taeyangin disease is classified into exterior-origin lower back (EOLB) disease and interior-origin small intestine (IOSI) disease by region of symptom. EOLB can be replaced with Oegam-yocheok and IOSI can be replaced with Naechok-sojang that is Korean pronuncation. EOLB disease is classified into lower back favorable symptomatology (LBFS) and lower back unfavorable symptomatology (LBUS). Lower back is to say Yocheok, so LBFS can be called Yocheok favorable symptomatology and LBUS can be called Yocheok unfavorable symptomatology. LBUS is to say paraparesis symptomatology or Haeyeok, that is Korean pronunciation, symptomatology. IOSI disease is classified into small intestine favorable symptomatology (SIFS) and small intestine unfavorable symptomatology (SIUS). Small intestine is to say Sojang, so SIFS can be called Sojang favorable symptomatology and SIUS can be called Sojang unfavorable symptomatology. SIUS is to say regurgitation symptomatology or Yeolgeok, that is Korean pronunciation, symptomatology.

갑상선 결절 환자에서 초음파 검사는 일차적 영상 진단법으로 정립되어 있으며 치료 결정을 위한 핵심적인 진단 역할을 갖는다. Korean Thyroid Imaging Reporting and Data System(이하 K-TIRADS)는 초음파 유형에 기초한 암 위험도 분류체계로서 실시간 초음파 검사를 시행하면서 쉽게 결절 진단이 가능하다는 장점을 갖고 있다. 개정된 2021 K-TIRADS는 결절의 초음파 분류 기준을 보다 명확히 하였고, 고위험 갑상선암의 의심 소견이 없는 환자에서 병리진단검사를 결정하는 결절 크기 기준을 개정하여 불필요한 병리진단검사를 최소화하고 적절한 갑상선암 진단 예민도가 유지되도록 개정하였다. 갑상선영상의학진료는 갑상선 결절 환자의 진단 및 비수술적 치료를 수행하는 중요한 임상적 역할을 가지고 있으며, 적절한 환자 진료를 위해서는 표준적 진료 지침에 근거하여 진료가 수행되어야 한다.

Objectives: This study analyzed the clinical characteristics of patients with functional dyspepsia (FD) who received Korean medicine treatment. Methods: A retrospective chart review was conducted to investigate sociodemographic characteristics, clinical characteristics, and prescribed treatments. The clinical records of 192 patients who visited Kyung Hee University Korean Medicine Hospital for FD from May 1, 2022, to May 31, 2023, were analyzed. In addition, the distribution of pattern identification and symptom type according to body mass index (BMI), as well as prescription history, were analyzed. Results: As the degree of obesity increased, the proportion of Spleen-Qi deficiency pattern patients decreased (p=0.012), and the proportion of damp-phlegm pattern patients increased (p=0.000). Additionally, as the degree of obesity increased, the proportion of patients with excess differentiation increased (p=0.002). The PDS (Postprandial distress syndrome) symptom type was significantly more frequent in the underweight and normal groups than in the overweight and obese groups, and the EPS (Epigastric pain syndrome) symptom type was more frequent in the overweight and obese groups. Regardless of the type of pattern identification, the most frequently used prescriptions were Naesowhajung-tang, Hanshin Naeso-san, and Sojeokgunbi-hwan granule. Conclusion: This study analyzed the medical records of patients with FD to elucidate the use of Korean medicine treatments. Our study is meaningful in that we found that the distribution of pattern identification and symptom patterns are linked to the degree of obesity in FD patients and identified the tendency for herbal medicine treatments to be prescribed in clinical practice.

This study explored the buffering effect of family resilience between family stress and adjustment of single parent family based on family resilience approach. Results of the study were as followed: First, single parents who had a lower level of family stress and a higher lever of family resilience reported a higher level of family adjustment. Second, family stress especially economic stress and relational stress influenced negatively on adjustment of single parent family. Family belief system, organizational pattern and communication processes of the three sub-factors of family resilience influenced positively on family adjustment. However the sub-factors of family resilience had more powerful effects than family stress. Third, family belief system, organizational pattern and communication processes of the three sub-factors of family resilience had a moderating effect between family adjustment and psychological stress and between family adjustment and relational stress. Especially the three sub-factors of family resilience had a buffering effect between family adjustment and relational stress. The results of this study had important implication for theory, research, and practice. The study showed that adjustment of single parent family could be significantly explained by family resilience rather than family stress. Accordingly strength perspective-based intervention focused on family resilience would be more effective than deficit perspective-based intervention based on family stress.

The construction of Reinforced Concrete (R/C) buildings with unreinforced masonry infills is part of the traditional building practice in many countries with regions of high seismicity throughout the world. When these buildings are subjected to seismic motions the presence of masonry infills and especially their configuration can highly influence the seismic damage state. The capability to avoid configurations of masonry infills prone to seismic damage at the stage of initial architectural concept would be significantly definitive in the context of Performance-Based Earthquake Engineering. Along these lines, the present paper investigates the potential of instant prediction of the damage response of R/C buildings with various configurations of masonry infills utilizing Artificial Neural Networks (ANNs). To this end, Multilayer Feedforward Perceptron networks are utilized and the problem is formulated as pattern recognition problem. The ANNs' training data-set is created by means of Nonlinear Time History Analyses of 5 R/C buildings with a large number of different masonry infills' distributions, which are subjected to 65 earthquakes. The structural damage is expressed in terms of the Maximum Interstorey Drift Ratio. The most significant conclusion which is extracted is that the ANNs can reliably estimate the influence of masonry infills' configurations on the seismic damage level of R/C buildings incorporating their optimum design.

Groundwater control is a significant issue in most underground construction. An estimate of the inflow rate is required to size the pumping system, and treatment plant facilities for construction planning and cost assessment. An estimate of the excavation-induced drawdown of the initial groundwater level is required to evaluate potential environmental impacts. Analytical and empirical methods used in current engineering practice do not adequately account for the effect of the jointed-rock-mass anisotropy and heterogeneity. The impact of geostructural anisotropy of fractured rocks on tunnel inflows is addressed and the limitations of analytical solutions assuming isotropic hydraulic conductivity are discussed. In this paper the unexcavated Zagros tunnel route has been classified from groundwater flow point of view based on the combination of observed water inflow and numerical modeling results. Results show that, in this hard rock tunnel, flow usually concentrates in some areas, and much of the tunnel is dry. So the remaining unexcavated Zagros tunnel route has been categorized into three categories including high Risk, moderately risk and low risk. Results show that around 60 m of tunnel (3%) length can conduit the large amount of water into tunnel and categorized into high risk zone and about 45% of tunnel route has moderately risk. The reason is that, in this tunnel, most of the water flows in rock fractures and fractures typically occur in a clustered pattern rather than in a regular or random pattern.

To enhance the acceleration performance and fuel consumption rate of a vehicle, the torque converter is modified or newly-developed with reliable analysis model. Up to recently, the one dimensional performance model has been used for the analysis and design of torque converter. The model is described with constant parameters based on the concept of mean flow path. When it is used in practice, some experiential correction factors are needed to minimize tole estimated error. These factors have poor physical meaning and cannot be applied confidently to the other specification of torque converter. In this study, the detail dynamic model of torque converter is presented to establish the physical meaning of correction factors. To verify the validity of model, performance test was carried out with various input speed and oil temperature. The effect of oil temperature on the performance is analysed, and it is applied to the dynamic model. And, to obtain the internal flow pattern of torque converter, CFD(Computational Fluid Dyanmics) analysis is carried out on three-dimensional turbulent flow. Correction factors are determined from the internal flow pattern, and their variation is presented with the speed ratio of torque converter. Finally, the sensitivity of correction factors to the speed ratio is studied for the case of changing capacity factor with maintaining torque ratio.

Purpose: Guided by Newman's theory of health as expanding consciousness, this study was done to explore the health experience of adolescents having depression. Methods: The researcher engaged in six to eight in-depth interviews with six adolescents. To begin the dialog, the researcher asked each participant to recount the first important memory he/ she had. All the narrative and diagram sharing between the researcher and participants were summarized according to recognized patterns and later elaborated in following interviews based on Newman's praxis methodology. Results: The significant individual pattern of early health experience was during the binding stage. At the turning point, individual patterns for participants revealed a personal journey of self-discovery and then emergence of reflecting behaviors. After the turning point, the participants changed as they evolved from the initial period of disruption and disorganization to organization at a higher level. The results suggest that adolescents who are depressive find new ways of relating to friends, family, healthcare providers, and the community by expanding their consciousness. Conclusion: Newman's praxis methodology is a good way of helping and studying adolescents with depression because it emphasizes participant-nurse/researcher partnership and pattern recognition as nursing practice.

The purpose of this study was to examine the effects of metastrategic exercise on a scientific reasoning strategy to control variables, and investigate the developmental patterns in the strategy usage within a given period. Two groups composed of 90 fifth grade students engaged in a scientific reasoning task over six daily sessions. Additionally, one group engaged in metastrategic exercise on fictional students' strategies of controlling variables on the task, while the other spent equivalent time on an unrelated task. Based upon results of the study, the following conclusions can be drawn. First, the metacognitive exercise on the strategy to control variables has positive and long-standing effects on the strategy performance at the reasoning task. The exercise also takes effect of near-transfer. Taking into consideration only about sixty minutes of metastrategic practice, the results provide the validity of the activity in order to develop children's reasoning strategies. Second, in a scientific reasoning task, each child seems to go through one out of two developmental patterns in their usage of reasoning strategies: gradual change or fundamental change. Considering the ratio of pattern of fundamental change between the two groups, it is clear that the metacognitive exercise influences the developmental pattern of strategy usage.
