Objectives The purpose of this study is to find the effect of Korean medicine treatments on pain reduction and range of motion recovery in patients with proximal tibia fractures. Methods We studied 15 patients who had been diagnosed as proximal tibia fracture. This study was conducted as retrospective observational study which analyzed patient's medical records with IBM SPSS statistics 25 program. We used numeric rating scale to evaluate pain reduction and range of motion to observe the patient's recovery. Results The average of numeric rating scale reduced statistically significantly from 5.26±1.38 to 2.73±1.17 (p<0.001). The average of knee flexion range of motion increased statistically significantly from 81.11±34.34 to 117.66±19.01 (p<0.01). Conclusions We found that Korean medicine treatments have a positive effect on pain reduction and knee rom improvement in patients with proximal tibia fractures.

본 논문에서는 동반논문에서 연구된 가진방법과 응답특성을 바탕으로, 실물크기의 철골건물에 설치될 점탄성 감쇠기의 설계과정을 다루었으며 가진실험을 수행하여 감쇠기의 진동제어효과를 검증하였다. 최대변위응답을 주어진 수준까지 감소시키기 위하여 요구되는 추가적인 감쇠비를 컨벡스 모델을 이용하여 구하였다. 모드변형에너지법을 이용하여 감쇠기 강성 변화에 따른 모드 감쇠비의 차이를 분석함으로써 감쇠기의 크기를 구하였다. 가새 강성의 효과 또한 모드의 특성을 구하는 과정에 반영하였다. 점탄성 감쇠기는 1층과 2층의 층간에 각각 2개씩 설치되었으며 응답효과를 검증하였다.

The purpose of this study was to identify the level of care givers' job stress, burn-out and stress coping strategies and to determine the mediator effect of coping strategies in the relationship between job stress and burnout. The research subjects were 193 care givers for the elderly in Jeollanamdo. The data analysis was performed by using SPSS Win 17.0. The results of this study were as follows; The level of care givers' job stress which they perceived was 2.68 points in a scale of 5 points, stress coping strategies was 2.39 points in a scale of 4 points, and the degree of burnout was 2.27 points in a scale of 5 points. There was a positive correlation between the care givers' job stress and burnout. There was a negative correlation between the job stress and stress coping strategies. There was a positive correlation between the stress coping strategies and burnout. And the stress coping strategies showed mediating effects between the care givers' job stress and burnout. Accordingly, we found that stress coping strategies had an mediating effect on care givers' burnout and various coping strategies were related to the burnout.

In this article, free vibration of double-walled carbon nanotubes (DWNT) based on nonlocal Kelvin's model have been investigated. For this purpose, a nonlocal Kelvin's model is established to observe the small scale effect. The wave propagation is employed to frame the governing equations as eigenvalue system. The influence of nonlocal parameter subjected to different end supports has been overtly examined. The new set of inner and outer tubes radii investigated in detail against aspect ratio. The influence of boundary conditions via nonlocal parameter is shown graphically. Due to small scale effect fundamental frequency ratio decreases as length to diameter ratio increases. Small scale effect becomes negligible on all end supports for the higher values of aspect ratio. With the smaller inner tube radius double-walled CNT behaves more sensitive towards nonlocal parameter. The results generated furnish the evidence regarding applicability of nonlocal model and also verified by earlier published literature.

In general, the response of bulk material is independent of its size when it comes to considering classical elasticity theory. Because the surface to bulk ratio of the large solids is very small, the influence of surface can be negligible. But the surface effect plays important role as the surface to bulk ratio becomes larger, that is, the contribution of the surface effect must be considered in nano-size elements such as thin film or beam structure. Molecular dynamics computation has been a conventional way to analyze these ultra-thin structures but this method is limited to simulate on the order of $10^6-10^8$ atoms for a few nanoseconds, and besides, very time consuming. Analysis of structures in submicro to micro range(thin-film, wire etc.) is difficult with classical molecular dynamics due to the restriction of computing resources and time. Therefore, in this paper, the continuum-based method is considered to simulate the overall physical and mechanical properties of the structures in nano-scale, especially, for the thin-film.

This study examined the mediating effect of self-concept on the relationship of peer victimization and social anxiety in middle school students. Study participants consisted of 235 (122 boys and 113 girls) first to third graders from three middle schools located in Seoul and Gyung-gi province. The School Violence Experience Scale and the Self-Concept Scale were used to measure research variables in the Korean version of Social Anxiety Scale for adolescents. Descriptive statistics and Pearson's correlation coefficients were calculated to examine the general tendency of study variables. In addition, structural equation modeling(SEM) was used to examine the mediating model. The study results were as follows. First, the level of peer victimization of the middle school students decreased the self-concept level; in addition, the self-concept level had a significant negative effect on the social anxiety level. Second, the self-concept level fully mediated the peer victimization and social anxiety relationship. In conclusion, a higher peer victimization level resulted in a lower self-concept level, that produced a higher social anxiety level in middle school students. The results suggested that implementing effective interventions to prevent peer victimization and encouraging a positive self-concept in middle school students would make a significant contribution to reducing social anxiety.

Purpose: The purpose of this study was to test the mediating effect of social support and resilience on the relationship between symptom distress and coping in young Korean breast cancer survivors. Methods: A purposive sample of 209 young breast-cancer survivors (mean age 39.9) was recruited for a cross-sectional survey, and the data were collected between June and October 2015. The instruments used in this study were the Memorial Symptom Assessment Scale-Short Form, the Multidimensional Scale of Perceived Social Support, 10-item Connor-Davidson Resilience Scale, and Cancer Coping Questionnaire. The collected data were then analyzed using the SPSS 23.0 and AMOS 23.0 programs. Results: Symptom distress was found to have a significant indirect effect on coping (beta=-.32, p=.002), but not a significant direct effect (beta=.06, p=.577). Additionally, based on the values obtained for the squared multiple correlation, symptom distress, social support, and resilience were found to explain 46.4% of the total variance of coping. Conclusion: Based on the results of this study, it can be suggested that in order to enhance young breast cancer survivors' ability to cope with the distress they commonly feel, intervention methods that strengthen resilience and provide social support should be developed and made available to them.

The shrinking critical dimensions of modern technology place a heavy requirement on optimizing feature shapes at the micro- and nano scale. In addition, the use of ion beams in the nano-scale world is greatly increased by technology development. Especially, Focused ion Beam (FIB) has a great potential to fabricate the device in nano-scale. Nevertheless, FIB has several limitations, surface swelling in low ion dose regime, precipitation of incident ions, and the re-deposition effect due to the sputtered atoms. In recent years, many approaches and research results show that the re-deposition effect is the most outstanding effect to overcome or reduce in fabrication of micro and nano devices. A 2D string based simulation software AMADEUS-2D $(\underline{A}dvanced\;\underline{M}odeling\;and\;\underline{D}esign\;\underline{E}nvironment\;for\;\underline{S}putter\;Processes)$ for ion milling and FIB direct fabrication has been developed. It is capable of simulating ion beam sputtering and re-deposition. In this paper, the 2D FIB simulation is demonstrated and the characteristics of ion beam induced direct fabrication is analyzed according to various parameters. Several examples, single pixel, multi scan box region, and re-deposited sidewall formation, are given.
