Total knee arthroplasty (TKA) is the gold standard of treatment for advanced osteoarthritis of the knee. The technical methods of cartilage regeneration procedures are now well-developed. Indications for this procedure are being expanded to the treatment of osteoarthritis. We compared data from 42 patients who underwent TKA and from 52 patients who underwent MCIC (autologous bone marrow mesenchymal-cell-induced-chondrogenesis). Allpatients were over 50 years of age and showed grade IV of the Kellgren-Lawrence classification. The TKA patients were older and predominantly female, compared to the MCIC patients. There was no difference between the two groups regarding the patient satisfaction. Clinical evaluation of the two groups showed significant mean improvement in the tKSS-A (pain) and tKSS-B (function) scores throughout the postoperative follow-up period. The monetary cost of TKA was relatively higher than that of MCIC. Therefore, considering the patient age and quality of life, MCIC is a potential treatment option for osteoarthritis as it thus delays the disease progression.

The present study aimed to survey doctors working in five university hospitals about internal customer satisfaction and organization commitment level in order to identify casual relationships through structure equations. According to the analysis, organization management had the biggest impact on internal customer satisfaction level, and the sooner the factor was named personnel, leadership, job, and compensation, the bigger the impact it had on the level. The research model was generally found to be good in terms of goodness of fit, considering the value of x² calculated as 103.314, the degrees of freedom of 38, GFI 0.924, AGFT 0.868, NFI 0.888, CFI 0.925, and RMSEA 0.086. In conclusion, the internal customer satisfaction level of doctors was significantly proportionate to organization commitment by means of their general satisfaction level, while also being directly proportionate to organization commitment (p<0.05). Meanwhile, statistical significance could not be found when measuring the effects of the doctors’ basic characteristics on the levels of internal customer satisfaction and general satisfaction in hospitals.

Background and Objectives : Branchial cleft anomalies are encountered rarely in clinical practice. We reviewed medical records of branchial cleft anomalies according to age and sex distribution, site distribution, characteristics of mass on physical examination, location of mass, preoperative diagnosis, type of branchial cleft cyst and report our experience with 25 cases of branchial cleft anomalies. Materials and Methods : A review of medical records was performed on 25 cases of branchial cleft anomalies diagnosed in pathologic report from January, 1990 to March, 2000. Result : Sex distribution was 11 male and 14 female, age distribution was most common in third decade which was 8 cases(32%). Site distribution was predominant in left side(13 cases), and in physical examination, the characteristics of the mass was nontender(76%), mobile(60%), soft(80%). The lesion site was submandibular area in 2 cases, upper 1/3 portion of sternocleidomastoid muscle(SCM) in 2 cases, middle 1/3 portion of SCM in 20 cases and parotid area in 1 case. The preoperative diagnosis was branchial cleft cyst in 16 cases, cervical lymphadenitis in 3 cases, tuberculous lymphadenitis in 3 cases, branchial cleft fistula in 1 case, dermoid cyst in 1 case and parotid mass in 1 case. Among 25 cases, first branchial cleft cyst was seen in 4 cases, second branchial cleft cyst in 20 cases and second branchial cleft fistula in 1 case. Conclusion : The clinical history of recurrent neck inflammatory episodes in young patients and nontender, mobile, soft neck mass should raise the suspicion of this entity. Investigation using CT scanning in combination with aspiration is useful. Treatment of all branchial cleft anomalies is complete surgical excision because there is lack of spontaneous regression, a high rate of recurrent infection, the possibility of other diagnosis, and rare malignant degeneration. Complete removal without complications depends on a good understanding of regional embryogenesis, a knowledge of the surrounding structure, and awareness of the different anatomical presentation.

보건의료분야에서의 인공지능기술(AI) 사용 의도와 태도에 관한 연구

본 연구는 UTAUT 모델을 이용하여 보건의료분야 대학생들의 인공지능기술(Artificial Intelligence Technology, AI)의 사용 의도와 태도에 영향을 미치는 요인들을 규명하기 위해 시행되었다. 연구대상은 278명의 대학생으로, 2016년 5월 15일부터 6월 14일까지 자기기입식 설문지를 통하여 자료를 수집하였다. 연구결과 성과기대, 사회적 영향, 업무의 유용성, 불안요인이 사용 의도에 유의미한 영향을 미치는 것으로 나타났다. 그리고 성과기대, 업무의 유용성, 불안요인은 태도에 유의미한 영향을 미치는 것으로 나타났으며, 사용 의도는 태도에 영향을 미치는 것으로 나타났다. 불안요인과 업무의 유용성이 태도에 미치는 직접 효과가 사용 의도에 의해 부분 매개하는 것으로 나타났다. 대학생들의 AI 기술에 대한 긍정적인 사용 의도와 태도를 높이기 위해서는 사실에 근거한 정확한 정보전달과 막연한 불안감을 줄이면서 성과기대, 사회적 영향, 인지된 유용성을 향상시키는 것이 중요한 것으로 나타났다. The purpose of this study was to identify the factors affecting intention and attitude of artificial intelligence technology(AI) of university students in healthcare using UTAUT model. Participants were 278 college students and the data were collected through self-reported questionnaire from May 15 to June 14, 2016. The collected data were analyzed using PASW Statistics/AMOS 22.0. The results were as follows. The effect of expectation factor, social influence, usefulness of work, anxiety factor had a significant effect on use of AI technology Intention. Factor of expectation effect, social influence, usefulness of work, anxiety factor had a significant effect on use of AI technology. As a result of verifying the significance of the indirect effect, it can be seen that the direct effect of the anxiety factor on the attitude factor is partially mediated by the use intention factor and the intention to use was partially mediated in the direct effect of the usefulness factor of the task on the attitude factor. This result means that it is important to increase the expectation factors, social effects, and perceived usefulness through accurate information based on facts and to reduce vague anxiety in order to increase the positive intention and attitude of university students' use of AI technology.

Objectives : This study applied the research model of Bontis (1998), which has been used to investigate everything from business corporations to hospitals in Korea, examined its generalizability and attempted to verify which factors of the intellectual capital affects organizational performance, represented by indicators for the clinical and financial performance of hospitals. Methods : Primary data for the study were collected from 91 general hospitals through self-administered questionnaires, and secondary data on clinical and financial performance of hospitals were collected form existing statistics. Collected data were analyzed with SPSS 11.5 (ver.) and AMOS 18.0 (ver.). Results : It was found that only human capital and customer capital had indirect effects on hospital performance. It was also revealed that structural capital had a direct effect on clinical performance, and an indirect effect on financial performance. Conclusions : This result means that there is a need to individually consider both the clinical performance and financial performance when measuring the organizational performance of a hospital, and it also shows that positive improvement in the clinical performance can contribute to the improvement of the financial performance through this process.
