Objectives: The purpose of this study was to conduct a clinical analysis of gastrointestinal cancer patients treated with Korean medical therapy. Methods: We analyzed a retrospective review of 226 gastrointestinal cancer patients treated in the cancer center of a Korean medicine hospital from February 2012 to August 2017. The patients' general characteristics, including the tumor, origin, stage of cancer, type of treatment, and chief complaint, were investigated before and after the treatment. Results: The largest proportion of tumor origins in total patients and inpatients was gastric cancer. Overall, 54.9% of the patients' tumors were stage IV. In total, 65.9% of patients visited the Oriental hospital for combination treatment with conventional medicine. The patients' chief complaints were abdominal discomfort, general weakness, and general cancer-related pain. Conclusions: This study presented the characteristics of patients with gastrointestinal cancer treated with Oriental medicine. Further advanced studies of Oriental medical cancer treatments are needed, based on the findings of this study.

Purpose - Many studies show that dissatisfied customers are silent rather than expressing complaints directly to firms. Although silent voices are pervasive in service failure, they have received little attention from researchers. Silence implies a multidimensional nature, not just the opposite of voice. This study focuses on two types of silent students in higher education: acquiescent silence and defensive silence. This study also proposes cognitive trust and affective trust as variables affecting student silence. The objective of this study is to analyse the effects of trust types on student silence and exit intention. Research design, data, and methodology - To test the proposed model, this study conducted a survey with undergraduate students who selected silence in a dissatisfied relationship with a professor. Respondents were asked to respond to the questionnaire, recalling the dissatisfaction at that time. A total of 300 students was surveyed from whom 275 completed questionnaires was obtained. The structural equation model analysis was used for the hypothesis test. Results - First, cognitive trust was negatively related to acquiescent and defensive silence. Second, affective trust was negatively related to acquiescent and defensive silence. Third, cognitive trust was negatively exit intention, but affective trust didn't significantly reduce exit intention. Forth, acquiescent silence was positively related to exit intention, but defensive silence didn't have a significant positive impact on exit intention. Thus, a key result of this analysis was that acquiescent silence enhances exit intention. Conclusions - The findings of the study provide a better understanding of the types of silence, and the role of trust, thus furthering the implication of student reactions to dissatisfaction. In particular, this study is meaningful in that it confirms the value of student silence in the context of complaint management. Acquiescent silence should be more importantly managed because it has stronger negative motive than defensive silence. Acquiescent silence is reduced through various channels(mail, telephone, counseling) that can express complaints. Cognitive trust and affective trust are a essential factors in reducing silence. Also, in explaining exit intention, cognitive trust plays a more important role than affective trust.

지방상수도에서 이물질에 의한 수질민원은 수돗물에 대한 불신을 초래하고 음용률을 저해하는 가장 큰 요인이라 할 수 있다. 본 연구에서는 수질민원 대상지역의 이물질 수집 및 시료의 정성 및 정량분석을 실시하여 이물질에 함유되어 있는 화합물과 원소성분을 검출함으로서 이물질 발생의 원인을 밝히고 해결방안을 모색하고자 하였다. 또한 상수관로 내부의 이물질로 인해 지속적으로 발생하는 수질민원을 해소하고 수돗물에 대한 신뢰성 향상 및 양질의 수돗물 공급을 위한 방안을 마련하고자 하였다. 민원지역에서 포집된 이물질은 관로의 내부부식 및 노후화로 인한 부식생성물의 무기화합물뿐만 아니라 탄소(C) 및 산소(O)성분을 다량 함유한 유기화합물도 포함하고 있었다. 이물질에 대한 정확한 판단과 저감을 위해 객관적인 대상지역의 관상태평가가 필요한 것으로 조사되었다.

의료서비스를 이용하는 고객의견 대한 구현은 효과적이고 효율적인 관리가 중요하다. 이에 본 연구는 고객의 불만족 사항에 대한 내용의 의료융합적 분석을 확인하여 전략을 수립하고자하는 후향적 조사연구이다. 2014년 3월부터 2015년 2월까지 일 상급종합병원의 민원 319건을 대상으로 분석하였다. 본 연구에서는 초진보다 재진이, 입원환자보다는 외래환자의 불만족이 높았으며 불만족 분류 시 행정서비스의 업무절차, 진료 및 간호영역의 의사소통 및 설명부분에서 불만족이 높았다. 질병 분류에서는 소화기계와 암 진단관련 대상자들의 불만족이 높았다(p<0.05). 본 연구를 바탕으로 의료서비스의 질을 향상시키고 불만족의 재발을 막는 고객 지향적 의료융합 경영전략을 수립하기 위해 각 환자의 질환별 불만족 요인의 내용을 융합분석하고 지속적인 융합연구를 통해 질환별 구체적인 의료서비스 전략에 대해 유형을 구조화 할 필요가 있다.

Background: To evaluate the predictive role of a risk of malignancy index in discriminating between benign and malignant adnexal masses preoperatively. Materials and Methods: A total of 408 patients with adnexal masses managed surgically between January 2010 and February 2014 were included. The risk of malignancy indices (RMI) 1, 2, 3 and 4 were calculated using findings for ultrasonography, menopausal status, and CA125 levels. Histopathologic results were the end point. ROC analysis was used for the sensitivity and the specificity of the models. Results: Some 37.6 % of the cases were malignant in the postmenopausal group while 7.9 % were malignant in the premenopausal group. Pelvic pain was the most common complaint, and the majority of the cases were diagnosed at stage 3. The RMI 1, 2, 3 and 4 yielded percentage sensitivities of 76.1, 79.1, 76.1 and 76.1 and specificities of 91.5, 89.1, 90.6, 88.6, respectively. RMI 1 was the most reliable test in the general population according to AUC levels and Kappa statistics. From ROC analysis results of post/premenopausal women, the RMI 1 (cut off: 200) yielded sensitivities of 84.0/60.9 and specificities of 87.7/92.5. With RMI 2 they were 88.6/60.9 and 80.0/91.0, with RMI 3 84.0/60.9 and 87.7/91.8, and with RMI 4 (cut off:400) 81.8/47.8 and 83.6 /44.0. Although test performance of RMI methods were good in a general population and postmenopausal women, the RMI inter-agreement validity was only moderate or fair in premenopausal women. Conclusions: Our study confirms the effectiveness of RMI algorithms in postmenopausal women. However, more sensitive tests are needed for premenopausal women.

국토의 70%가 산지인 우리나라는 도로건설 등에 필요한 토지가 매우 부족할 뿐만 아니라 환경에 대한 국민들의 관심이 고조되어 터널 시공이 증가하는 추세이다. 남해고속도로 냉정~부산간 확장공사 대동1터널 시공 시 계곡부 위치 및 갱문 이격으로 저토피가 발생하였고, 민원 등으로 착공이 지연되어 관통부 변경이 불가피하였다. 이에 다중TSP를 적용하여 관통부 위치를 변경하였고 안정해석을 실시하였다. 해석결과 터널의 안정성에 문제가 없는 것으로 나타났으며, 시공 중 추가적인 안정성을 확보하고자 계측기 설치 및 기계굴착, 저토피 구간 추가 보강, 반단면 굴착을 실시하였다.

The timing chain system, which is a typical power transmission technology applied to a vehicle, has been widely used by the automotive industry because it is normally designed to last a car's lifetime. However, the timing chain system may cause some problems due to the shape of the chains and the polygonal behavior on contact between the chain and the sprocket. In addition, noise and vibration caused by transmission error are the most typical problems encountered by major automotive manufacturers and they are considered as the main source of customer complaint. The initial tension of the chain-sprocket system is thought to be the main cause of transmission error, and it is regarded as the source of engine vibration and noise. The initial tension of the chain system should be controlled carefully since a low initial tension can cause twisting, which may lead to a system malfunction, while a high initial tension can reduce the service life due to a worn down contact surface. In this paper, the kinematic analysis model is generated with various initial tensions, which are controlled by changing the shape of the fixed guide with the largest contact surface with chain. The results showed that the transmission error was minimized on a particular range of initial tension, and the tendency showed that the error changed with a higher sensitivity at a lower initial tension.
