The bending propertied of the 2 folded yams such as the bending rigidity, the coercive couple, the hysteresis energy and the residual curvature with various wool/polyester blend ratios and with variations of the single and 2-folded yarns twists were stylied for analyzing twist characteristics, inter and intra frictional effects. The value of the experimental specific bending rigidity of two folded staple yarns were in the range of 1.2 and 2.5 times of the estimated values, and the experimental specific bending rigidities of 2 folded yarns divided by the power of 1.2 of its linear density were almost same as the experimental specific bending rigidities of single yarns. The experimental specific bending rigidities of the 2 folded staple yarns were found to show the maximum values in the range of the same twist between the single and 2 folded yarns with increasing 2 folded yarn twist with fixed single yarn twist. The values of the coercive couple, the residual curvature and the hysteresis energy of the 2 folded staple yarns showed almost sane tendency as that of the specific bending rigidity. Maximum bending rigidity to wool/polyester blend composition was shown around the range of same blend composition, and maximum bending recovery was also shown in this range, then coercive couple and hysteresis energy were increased with polyester colnposition.

This study seeks to introduce grounded theory as a missiological research method, for the last three years, two major Korean academic jounals for missions studies have published only two articles that were based on field research, Barney G, Glaser and Anselm L. Strauss explained that grounded theory discovers theory from data systematically obtained from social research. In this study, I suggest that grounded theory be a methodology that is sustainable and does not demand too much time and resources. Grounded theory was introduced by Glaser and Strauss in 1967. Since then, this methodology was widely used, including nursing, social welfare, education. This theory was introduced to Korea in 1987. From then on, this theory was used various disciplines. And yet, the usage of this theory in missions study in the Korean language was not found. This study explains the key concepts of grounded theory: theoretical sampling, theoretical sensitivity, theoretical saturation, memoing and coding. This study, then, talks about the process of the theory. This study, then, provides benefits and limitation of grounded theory as a missiological research method.

This study, targeting Korean tertiary hospitals and general hospitals, aims to analyze how value chain model inhealth and medical institution suggested by Duncan and else influences on hospital management. A survey wasconducted to verify the actual proof analysis of this study model. 880 questionnaires were distributed to entire 88hospitals and 739 copies were returned from 76 hospitals. This study mainly consists of three steps to analyze theeffect value chain activity has on management performance of general hospitals. For the first step, we analyzedthe effects service delivery activity has on management performance. For the second step, we analyzed theeffects service support activity has on management performance and for the third, we analyzed the effectsinteraction between service delivery activity and service support activity has on management performance. Themain results of this study are as follows. First, in terms of the management performance of scale, the factors whichinfluenced on daily charge of outpatient were service activity before treatment, at the moment of treatment andvalue chain activity, while more important factors in daily charge of inpatient were organizational culture,organizational structure and value chain activity. In terms of management performance of quality, the factors whichinfluenced on the first medical examination rate of outpatient were service activity before, at the moment of andafter treatment, while activity at the moment of treatment, organizational structure, and value chain activity which isinteraction were more important factors in average length of stay. In terms of non-financial performance, themanagement performance factors which influenced on job satisfaction were service activity at the moment of, afterthe treatment and value chain activity, while organizational culture, strategy resources and value chain activitywhich is interaction were more important factors in job commitment. Secondly, all the service support activity,service delivery activity and value chain activity had statistically significant effect on management performance.Among the three factors, service support activity had relatively high effect than others.

Objective : The aims of this study are to investigate the correlation between spiritual well-being and the pattern of stress coping strategies, as well as understand how they impact depression and psychological well-being. Methods : We analyzed 320 undergraduate students in a capital area (135 males, 170 females; 15 students who answered irrelevantly were excluded). Spiritual well-being (religious and existential), stress coping strategies (active and passive), psychological well-being and, depression were rated using the Spiritual Well-Being scale, Ways of Coping checklist, Psychological Well-Being measurement, and Depression Scale (CES-D), respectively. For the analysis, we utilized Pearson correlation analysis and simple regression analysis. Results : The analysis revealed a positive correlation between Spiritual well-being and active coping strategies, a negative correlation between existential well-being and depression, and a positive correlation between religious well-being and psychological well-being. By regression analysis, it showed spiritual-well being affected depression negatively. Existential well-being, but not religious well-being, affected depression negatively. Furthermore, the impact of existential well-being on depression remained a strong predictor in males better than females. Existential well-being affected psychological well-being positively through active coping strategies. Conclusion : In this study, we verified a correlation between existential well-Being and active coping strategies which affected depression and psychological well-being in undergraduate students. 본 연구는 영성이 어떠한 대처방식을 통해 우울과 심리적 안녕감에 영향을 미치는지 알아보기 위해 경기도 소재의 대학생 320명을 대상으로 연구를 수행하였다. 영적 안녕 척도, 스트레스 대처방식 척도, 심리적 안녕감 척도, 우울 척도를 이용하여 대상자들을 평가하였으며 Pearson 상관 분석, 회귀 분석을 이용해 자료를 분석하였다. 영성은 심리적 안녕감, 적극적 대처방식과는 정적 상관관계를 우울과는 부적 상관관계를 보였다. 실존적 안녕은 우울과는 부적 상관관계를 종교적 안녕은 심리적 안녕감에 정적인 상관관계를 나타냈다. 영성이 영향을 미치는 각각의 변수에 대해 더욱 자세히 알아보기 위해 단순회귀분석을 시행하였고 영성은 우울에 부적으로 유의미한 영향을 주었다. 그 중 실존적 안녕이 우울에 유의미하게 부적 영향을 미쳤으며 종교가 있는 군과 남자 군에서 더욱 설명력이 높았다. 영성이 심리적 안녕과 스트레스 상황 시 적극적인 대처방식에 정적으로 유의미한 영향을 미쳤다. 결론적으로, 본 연구에서는 실존적 영성이 적극적 대처방식을 통해 우울과 심리적 안녕감에 긍정적 영향을 미치는 것을 확인 하였다. 이를 근거로 실존적 영성을 활성화 하는 치료적 개입을 통해 환자의 정신건강에 도움을 줄 수 있겠다.

Low-grade fibromyxoid sarcoma is a slowly growing soft tissue neoplasm that shows benign histologic features but may have clinical course of malignant disease. It has been reported to occur in the thigh, inguinal area, axilla, shoulder, neck, perineum or buttock. However, there have been few cases of abdominal organ involvement. A 21-year-old woman presented with a large palpable abdominal mass. A 7×4 cm sized round soft tissue tumor at right upper quadrant area was identified by abdominopelvic CT scan. Percutaneous ultrasound-guided biopsy revealed features of spindle cell tumor. On exploration, the tumor originated from transvers colon and was attached to gastrocolic ligament, transverse mesocolon and stomach. The tumor could be dissected with transverse colectomy and partial gastrectomy. The excised tumor, measuring 7×5×5 cm, was well demarcated and appeared as an ovoid mass with firm and myxoid cut surface. She was diagnosed with low-grade fibromyxoid sarcoma arising from transverse colon, and is currently being followed-up without recurrence or metastasis. (Korean J Gastroenterol 2014;64:375-379)

Objective: The aim of this study is to develop and verify an indirect method for estimating sitting posture by observing pelvic tilt and lumbar lordosis of visual display terminal (VDT) users. Background: Depending on the wrong sitting posture, musculosketal disorders (MSDs) such as low back pain may occur. In the case of the general public, it is impossible to observe the sitting posture quantitatively. Therefore, we developed a system that can estimate the user’s sitting posture through two IMUs. Method: Five participants were conducted test. Participants conducted paperwork for each one hour through a computer. When participants are working, we took video (Kinect V2, USA), measuring body pressure distribution by pressure mat (X3 LX100, Canada) and lumbar angle by two IMUs every fifteen minutes. Results: Results showed that lumbar lordosis and pelvic tilt of the subject could be indirectly estimated with only two IMUs. We could identify posterior pelvic tilt in user’s sitting posture as time goes on. Conclusion: This result can be alternative method of observing and evaluating the sitting posture of a person using VDT for a long time. Application: The results can evaluate the sitting posture of the VDT users, and can lead to sitting in a good posture.
