  • 본 연구의 목적은 청소년 선수들의 긍정적 사고와 대처유연성 및 소진의 구조적 관계를 검증하는 것이다. 연구대상은 청소년 선수 333명이었다. 자료처리는 SPSS 20.0과 AMOS 20.0을 이용하여 전체연구 단위의 적합도 검증을 확인한 후 가설검정을 실시하였으며, 그에 따른 결과는 다음과 같았다. 첫째, 청소년 선수들의 긍정적 사고는 대처유연성의 하위요인 모두에 유의한 영향을 미치는 것으로 나타났다. 둘째, 대처유연성의 지각된 대처자원과 대처행동 유연성은 소진에 부적인 영향을 미치는 것으로 나타났다. 셋째, 긍정적 사고는 소진에 유의미한 영향을 미치지 않는 것으로 나타났다. 결론적으로 긍정적 사고가 개인 내면의 정보에 토대하는 변인임에도 불구하고 긍정적 사고가 심리적 소진에 직접적인 영향을 미치지는 않았지만 대처유연성을 통해 소진이 예방될 수 있음을 확인하였다.

  • While conventional electronic devices have been fabricated on the rigid and brittle Si based wafer as a semiconducting substrate, future devices are increasingly finding applications where flexibility and stretchability are further integrated to enable emerging and wearable devices. To achieve high flexibility and stretchability, various approaches are investigated such as polymer based conducting composite, thin metal films on the polymer substrate, and structural modifications for stretchable electronics. In spite of many efforts, it is still a challenge to identify a solution that offers both high stretchability and superior electrical properties. In this paper, we introduce a highly stretchable entangled-mesh graphene showing a potential to address such requirements as stretchability and good electrical performance. Entangle-mesh graphene was synthesized by CVD graphene on the Cu foil. To analyze the mechanical properties of entangled-mesh graphene, endurance and stretching tester have been used.

  • Background: Abdominal bracing exercise (ABE) and abdominal hollowing exercise (AHE) improve the lumbar flexibility and pulmonary function in various patients, yet the efficacy of ABE or AHE have not yet been evaluated. Objects: The purpose of this study was to compare the lumbar flexibility and pulmonary function during both ABE and AHE in healthy adults. Methods: The study included 40 healthy adults, who were randomly divided into the experimental group and control group, each with 20 subjects. All subjects performed ABE (experimental group) and AHE (control group). The lumbar flexibility such as trunk flexion test (sitting and standing position) and schober test and pulmonary function such as the spirometer including forced vital capacity (FVC) and force expiratory volume in one second ($FEV_1$) and chest circumference measurement (middle and lower chest) were measured, respectively. Two-way repeated analysis of variance was used to compare the lumbar flexibility and pulmonary function, respectively. Results: No significant effects of lumbar flexibility were observed on trunk flexion test from the sitting position (P=.478) and standing position (P=.096) in the ABE than in the AHE. However, the length of ABE was longer significantly than it of AHE (P=.024). No significant effects of lung function were observed on the FVC (P=.410) and $FEV_1$ (P=.072) in the ABE group than in the AHE group. And also, no significant effects of chest circumference measurement were observed on the inspiration (P=.468) and expiration (P=.563) in middle chest circumference and inspiration (P=.104) and expiration (P=.346) in lower chest circumference. Conclusion: This study indicated that the ABE is only more effective in lumbar flexibility by lumbar length difference than AHE in healthy adults.

  • The aim of this study was to compare the duration of hamstring flexibility improvement after 3 stretching interventions in people with limited hamstring flexibility. Twenty-two subjects (12 men, 10 women) with limited hamstring flexibility of the dominant leg received 3 stretching interventions- modified dynamic stretching (MDS), hold-relax (HR), and static stretching (SS)-in a random order. All the subjects received all 3 interventions at intervals of at least 24 hours to minimize any carry-over effect. Modified dynamic stretching was applied as a closed kinetic chain exercise in the supine position by using the sling suspension system (Redcord Trainer(R)). The SS and HR interventions were individually performed in the straight leg raising (SLR) position, and all 3 interventions were performed for 3 minutes. Outcome measures included passive knee extension (PKE) measurements. Five post-test measurements were recorded for all subjects at 3, 6, 9, 15, and 30 minutes after the interventions. MDS was associated with a significant increase in knee extension range of motion even at 30 minutes post-treatment. In contrast, the HR and SS stretching methods showed increased hamstring flexibility for only 6 minutes post-treatment. Improvements in the range of motion of knee extension (indicating enhancement in hamstring flexibility) with MDS were maintained longer than those with the HR and SS interventions. Therefore, MDS may be more effective than the other interventions for maintaining hamstring flexibility.

  • This paper uses dynamic computer simulation techniques to develop and apply a multi-criteria procedure using non-destructive vibration-based parameters for damage assessment in truss bridges. In addition to changes in natural frequencies, this procedure incorporates two parameters, namely the modal flexibility and the modal strain energy. Using the numerically simulated modal data obtained through finite element analysis of the healthy and damaged bridge models, algorithms based on modal flexibility and modal strain energy changes before and after damage are obtained and used as the indices for the assessment of structural health state. The application of the two proposed parameters to truss-type structures is limited in the literature. The proposed multi-criteria based damage assessment procedure is therefore developed and applied to truss bridges. The application of the approach is demonstrated through numerical simulation studies of a single-span simply supported truss bridge with eight damage scenarios corresponding to different types of deck and truss damage. Results show that the proposed multi-criteria method is effective in damage assessment in this type of bridge superstructure.

  • 인지 복합성과 대처 유연성은 심리적 적응에 밀접한 관계를 가진다는 기존 연구에 근거한다면 상담의 주요과정인 역전이 관리능력에도 정적인 영향을 미칠 수 있을 것으로 추론할 수 있다. 본 연구에서는 상담자의 인지 복합성과 대처 유연성이 역전이 관리능력에 미치는 영향에 대해 알아보았다. 본 연구를 위해 서울 및 수도권 소재의 대학생활 상담소, 상담센터, 학교, 병원 등에 근무하는 상담자 128명(여 108명, 남 20명)을 대상으로 하여 설문조사를 실시하였다. 연구 결과, 상담자의 인지 복합성 수준에 따른 역전이 관리능력에는 차이가 없는 것으로 나타났으나, 상담자의 대처 유연성의 수준에 따라서는 역전이 관리능력에 유의미한 차이가 있었다. 또한 중다회귀에서 역전이 관리능력에 있어서 대처 유연성이 인지 복합성에 비해 보다 많은 영향을 미치는 것으로 나타났다. 이는 역전이 관리능력을 함양하기 위한 방안으로 상담자의 대처유연성을 향상시키는 것이 중요함을 시사하며 이에 초점을 둔 상담자 훈련 프로그램 개발이 필요하다.

  • The purpose of this paper was to explain on the conceptualisation of the Halal Orientation strategy (HOS) based on operation strategy perspective. The four variables constitute in HOS are staffing, materials, production process and storage together with transportation. By focusing on HOS, the manufacturers reinforce improvement in quality, cost control, time and flexibility of the production Halal food industry in Malaysia which is the performance objective of market competitiveness in Malaysia context. A self-administered questionnaire was designed and used to assess the significant of HOS that lead to improve quality, cost control, reduction in time and the flexibility among Halal food manufacturers in Malaysia. From a total of 443 Halal food manufacturers were involved in this study, only 137 respondents are usable for this research. The study showed significant results for the manufacturers to focus in Halal Orientation strategy (HOS) which have positive impacts on quality, cost control, time and flexibility. This research aimed to measure the HOS among food firms in Malaysia and to determine HOS in relation with the performance objective of operational outcomes.

  • Purpose: This study was done to identify the effects of an exercise correction program for scoliosis on the physical and psychological functions of middle-school students with scoliosis. Method: The design of this study was a nonequivalent control group pretest-posttest design. The students who participated in the study were 45 middle school students with scoliosis. Twenty-four students were assigned to the experimental group and 21 to the control group. The treatment given to the experimental group was a scoliosis correction exercise program. The scoliosis correction exercise program was given 3 times a week for a period of 12 weeks. Result: For Cobb's angle, a significant decrease was observed in the experimental group. For flexibility, the sit-and-reach test showed a significant increase in the experimental group. For depression, self-esteem and body satisfaction, the difference between the two groups was not significant. Conclusion: Based on the above results, the effects of a spine correction exercise program produced a decrease in Cobb's angle and an increase in the sit-and-reach test for flexibility. This program is not expensive and is convenient, and thus has been identified as a good nursing intervention for correcting scoliosis.
