Kim,See-hyung,Kwock,Yong-sub,Kim,Young-tae 한국문화관광학회 2000 문화관광연구 Vol.2 No.1

The objectives of this study were to develop theoretical model that outlined the antecedents of satisfaction in an industrial buying context, to investigate product usage level as an outcome of the two economic factors, and to examine the relationships of product, usage level and service factor with customer satisfaction as the organizational market for hospitality is growing. To figure out the relevant constructs and variables for this study, related literature was reviewed. Then, to satisfy the purposes of the study, structural equation modeling method was utilized with a confirmatory factor analysis. A confirmatory factor analysis examined a four-factor solution developed from the factor analysis. Also, goodness-of-fits for measurement model and structural model were evaluated to test the reliability of both models. The various measures of overall model goodness-of-fit lend acceptable level of support to deeming the results an acceptable representation of the hypothesized constructs. Based on the acceptable level of support for the goodness-of-fit tests, the relationships among the constructs in the model were examined. Finally, two alternative models were proposed and compared to the original model.

Background: In patients with endometrial carcinoma, preoperative evaluation of exact staging has important prognostic and therapeutic implications. The incidence of pelvic and aortic lymph node involvement in endometrial carcinoma depends on grade of tumor differentiation and depth of myometrial invasion. Material and method: To evaluate whether MRI provides a preoperative assessment for staging of endometrial carcinoma, MRI was undertaken in 28 patients, a few weeks before operation. Myometrial invasion was devided in three categories, and involvement of cervix, adnexa, and pelvic cavity were classified. Result: The results of MR imaging were compared with these of pathology. The preoperative MRI staging of endometrial carcinoma was correct in 22 out of 28 patients. In the evaluation of myometrial invasion, the MR imaging underestimated in 4 cases and overestimated in 1 case. Conclusion: In patients with endometrial carcinoma, MR imaging is very useful in the assessment of the depth of myometrial invasion, stromal invasion of cevix, lymphatic & pelvic metastases and extent of the lesion.

연구목적 : 일반적으로 생체는 각종 스트레스에 반응하여 적응(adaptation) 기전이 나타난다. 이러한 적응 기전과 관련하여 포유동물의 중요한 억제성 신경전달계인 GABA성 신경전달계의 스트레스성 자극에 대한 반응양상에 대한 연구가 진행되고 있다. 신경전달의 변화양상은 부하된 스트레스의 종류 및 기간에 따라 다양하게 나타나므로 더욱 상세한 연구를 필요로 한다. 방 법 : 본 연구에서는 하루 2시간의 부동화 스트레스를 반복적으로 2주간 부하한 흰쥐의 뇌조직에서 GABA성 신경전달의 변화 양상을 관찰하고자 하였다. 수용체 결합반응을 통하여 GABA 수용체의 각 component별 배위자들의 각 수용체에 대한 결합 반응의 변화 양상을 정상 대조군와 비교하여 보고, 유의한 변화가 있는 부분의 상세한 검정을 위하여 포화결합반응을 통하여 친화력(Kd) 및 최대결합력(Bmax)에서의 변화양상을 검색하였다. 뿐만 아니라 GABA성 신경전달에 관여하는 중요한 신경전달체인 내인성 GABA의 함량과 대사효소인 GABA transaminase의 활성도의 변화양상도 검색하였다. 결 과 : 연구결과 반복적인 부동화 스트레스는 GABA 수용체 효현제인 [³H]muscimol의 흰쥐 뇌조직 GABA 수용체에 대한 결합도에는 별다른 영향을 미치지 않았다. 대뇌피질조직의 GABA 대사효소인 GABA transaminase 활성도를 감소시켰으나, 피질조직외의 다른 조직의 GABA transaminase 활성도나 내인성 GABA의 농도에는 별다른 영향을 미치지 않았다. 반복적인 부동화 스트레스를 부하한 흰쥐의 대뇌피질, 해마 및 시상하부 조직에서는 [³H]flunitrazepam의 수용체 결합도가 감소하였으며, 포화결합 반응결과 수용체의 수가 감소하였음을 확인하였다. 결 론 : 이상의 결과를 요약하면, 흰쥐에게 부하한 반복적인 부동화 스트레스는 뇌조직의 benzodiazepine 수용체의 수를 감소시킴으로써 GABA성 신경전달을 감소시키며, 이러한 GABA성 신경전달계의 변환은 생체에서 스트레스로 인한 행동장애의 한 기전이 될 수 있을 것으로 생각되었다. Objectives : Changes of GABAergic neurotransmission in response to the application of different types of environmental stress have been the subject of research for over two decades. However, the nature of the changes induced by stress appear to show a dependent phenomena on the type and duration of stressor agent employed. Methods : For this reason, this study was performed to observe the effects of repeated stress on the radioligands binding to GABAA/benzodiazepine receptors of discrete brain regions. The author also examined the activity of GABA transaminase and the concentration of endogenous GABA. Male Sprague-Dawley rats, weighing 150-200g were forced to suffer an immobilization stress for 2 hours during 14 consecutive days. Results : Repeated immobilization stress decreased the binding of [3H]flunitrazepam on the benzodiazepine receptor in the cortex, hippocampus and hypothalamus. Saturation experiments followed by scatchard analyses of the results showed decreased density of benzodiazepine receptor and the affinity remained unchanged. Repeated immobilization stress did not affect the binding of [3H]muscimol on the GABAA receptor, the activity of GABA transaminase, and the concentration of endogenous GABA in the brain regions. Conclusions : From these results, it can be concluded that repeated immobilization stress modulated GABAergic neurotransmission via downregulation of the benzodiazepine receptor in the brain.

Assessment of solid components of borderline ovarian tumor and stage I carcinoma: added value of combined diffusion- and perfusion-weighted magnetic resonance imaging

Kim, See Hyung Yeungnam University College of Medicine 2019 Yeungnam University Journal of Medicine Vol.36 No.3

Background: We sought to determine the value of combining diffusion-weighted (DW) and perfusion-weighted (PW) sequences with a conventional magnetic resonance (MR) sequence to assess solid components of borderline ovarian tumors (BOTs) and stage I carcinomas. Methods: Conventional, DW, and PW sequences in the tumor imaging studies of 70 patients (BOTs, n=38; stage I carcinomas, n=32) who underwent surgery with pathologic correlation were assessed. Two independent radiologists calculated the parameters apparent diffusion coefficient (ADC), $K^{trans}$ (vessel permeability), and $V_e$ (cell density) for the solid components. The distribution on conventional MR sequence and mean, standard deviation, and 95% confidence interval of each DW and PW parameter were calculated. The inter-observer agreement among the two radiologists was assessed. Area under the receiver operating characteristic curve (AUC) and multivariate logistic regression were performed to compare the effectiveness of DW and PW sequences for average values and to characterize the diagnostic performance of combined DW and PW sequences. Results: There were excellent agreements for DW and PW parameters between radiologists. The distributions of ADC, $K^{trans}$, and $V_e$ values were significantly different between BOTs and stage I carcinomas, yielding AUCs of 0.58 and 0.68, 0.78 and 0.82, and 0.70 and 0.72, respectively, with ADC yielding the lowest diagnostic performance. The AUCs of the DW, PW, and combined PW and DW sequences were $0.71{\pm}0.05$, $0.80{\pm}0.05$, and $0.85{\pm}0.05$, respectively. Conclusion: Combining PW and DW sequences to a conventional sequence potentially improves the diagnostic accuracy in the differentiation of BOTs and stage I carcinomas.

A Comparative Analysis of International Travelers` Perception toward Tourism Destination on Four Product Evaluation

See Hyung Kim(김시형) 한양대학교 관광연구소 2011 觀光硏究論叢 Vol.23 No.3

국제관광객의 관광 방문지에 대한 인식은 다양한 요인이 방문지 평가에 영향을 미칠 수 있다. 본 연구에서는 국제관광객의 출신 국가에 따른 요소가 여행지에서 경험한 네 가지 평가요소에 미치는 영향에 관해 고찰하였다. 여행 방문 대상국인 홍콩에 대한 인지된 서비스 품질, 인지된 가치, 전반적인 만족도, 그리고 재방문 의향에 관한 설문조사를 7개국 방문객을 대상으로 실시하였다. 네 가지 요인들 간에는 통계적으로 유의한 관계가 입증되었으며, 방문객들은 국적에 따라서 여행지 평가에 관한 네 가지 요인에 상대적으로 상이한 의미를 부여하고 있었다. 결론적으로, 미국과 호주, 그리고 유럽 방문객의 여행 목적지인 홍콩에 대한 서비스 품질, 인지된 가치, 전반적인 만족도, 그리고 재방문 의사에 관한 전반적인 평가는 아시아 국가(중국, 대만, 싱가폴, 말레이시아)의 방문객 보다 상대적으로 높게 나타났다. 하지만 네 가지 평가 기준에 따른 개별 요인의 평가 결과는, 전반적인 평가 결과와는 달리 방문객의 출신 국가에 따라서 비교적 다양한 반응이 형성되어 방문객의 국적을 바탕으로 동서양의 문화권을 공통분모로 일관된 해석을 적용하기 보다는 특정 국가의 문화적 배경 뿐 만이 아니라 국제 여행에 직접적으로 혹은 간접적으로 영향을 행사하는 요인에 관해서도 고려해야 하겠다. The purpose of this study was to examine the differences in the evaluation of international travelers` experience based on their origin of country. Foreign visitors from seven countries were asked the four product evaluation variables (perceived service quality, perceived value, level of satisfaction, and revisit intention) after visiting Hong Kong. The relationship among the four product evaluation variables was significant and there were significant differences among foreign travelers based on their country of origin. In sum, visitors from Western countries inclined to evaluate their experience higher than those from Eastern countries. However, the relative significance of evaluation was not consistent across countries.
