  • Experimental equipment for studying the sorption properties of iodine sorbents using radioactive methyliodide has been developed. The sorption capacity index ${\alpha}$ is proposed as a criterion parameter for assessing the quality of impregnated activated charcoals. It was found that this parameter does not depend on the dynamic conditions during the sorbent test. It was shown that values of the sorption capacity index allow to recommend iodine sorbents for industrial gas cleaning processes.

  • As student-centered learning grows, formative peer assessment practices have been universally used in various fields. According to the review of traditional peer assessment practices, the formative peer assessment has five common stages: planning, assessing (giving feedback), receiving feedback, reflection, and revising. As the each stage of traditional formative peer assessment has some weaknesses, the study discusses solutions that are recommended for dealing with the problems by introducing the potential benefits of web-based peer assessment. Then, desirable future trends of web-based peer assessment are suggested. The author hopes that understanding the potential benefits of web-based formative peer assessment will promote the proper use of peer assessment and render positive effect on student learning.

  • Purpose: It is difficult to obtain biopsies from gastrointestinal stromal tumors (GISTs) prior to surgery because GISTs are submucoal tumors, despite being the most common nonepithelial neoplasms of the gastrointestinal tract. Unlike anatomic imaging techniques, PET-CT, which is a molecular imaging tool, can be a useful technique for assessing tumor activity and predicting the malignant potential of certain tumors. Thus, we aimed to evaluate the usefulness of PET-CT as a pre-operative prognostic factor for GISTs by analyzing the correlation between the existing post-operative prognostic factors and the maximum SUV uptake (SUVmax) of pre-operative 18F-fluoro-2-deoxyglucose (FDG) PET-CT. Materials and Methods: The study was conducted on 26 patients who were diagnosed with gastric GISTs and underwent surgery after being examined with pre-operative FDG PET-CT. An analysis of the correlation bewteen (i) NIH risk classification and the Ki-67 proliferation index, which are post-operative prognostic factors, and (ii) the SUVmax of PET-CT, which is a pre-operative prognostic factor, was performed. Results: There were significant correlations between (i) SUVmax and (ii) Ki-67 index, tumor size, mitotic count, and NIH risk group (r=0.854, 0.888, 0.791, and 0.756, respectively). The optimal cut-off value for SUVmax was 3.94 between "low-risk malignancy" and "high-risk malignancy" groups. The sensitivity and specificity of SUVmax for predicting the risk of malignancy were 85.7% and 94.7%, respectively. Conclusions: The SUVmax of PET-CT is associated with Ki-67 index, tumor size, mitotic count, and NIH classification. Therefore, it is believed that PET-CT is a relatively safe, non-invasive diagnostic tool for assessing malignant potential pre-operatively.

The purpose of this study is to evaluate patients' hospital experience and satisfaction using telephone interview and to study the usefulness for telephone interview at assessing patient satisfaction. Method : The 846 patients who were discharged from September 17, 1996 to October 11, 1996 were targeted were telephoned. The informations gathered telephone survey were processed by computer and analyzed for the patient satisfaction, contributing factors. Result : The 846 patients who were discharged from September 17, 1996 to October 11, 1996 were called and 197 patients(23.3%) were successful interviewed. 51.3 percent of respondents were male and mean age is 39 years mean LOS(length of stay) is 13 days and 110(56.1%) patients were admitted by outpatients clinic. The mean calling-time is 5.5 minutes. There is no significant difference between interviewers(telemarketer) in patients satisfaction. Seven telephone interviews are possible by interview a day. There in no significant difference between groups in patients satisfaction in length of stay, path of admission, the interval between discharge and interview. 97.5 percent of respondents were satisfied with telephone interview and 81.7% were satisfied with overall satisfaction and 79.4 % of respondents were good response in interviewers' conclusion. Of six variables that were found to be correlated with telephone interview and eight variables correlated with overall hospital satisfaction, a multiple logistic regression analysis revealed that two most important variables which are significantly correlated with telephone interview are to meet doctors, not ask tediously then three variables which are with overall satisfaction are doctors explain, subject response, convenient facilities. Conclusion : The patients interviewed are satisfied with telephone interview. Telephone interview is good method for assessing patient satisfaction, making high levels of patient satisfaction and for hospital marketing.

  • 본 연구는 CIPP모형을 활용하여 항공서비스교육의 성과를 평가하고자 한다. CIPP모형의 상황평가(Context), 투입평가(Input), 과정평가(Process), 산출평가(Product)를 중심으로 요인을 도출하고 항공서비스교육의 만족도와 재추천에 영향을 미치는 요인을 분석하였다. 그 결과 만족도에는 상황평가(C)의 교육목표, 과정평가(P)의 상호작용, 프로그램관리, 산출평가(P)의 직무성과 요인이 긍정적인 영향을 미쳤으며, 투입평가(I)의 인적자원은 부정적인 영향을 주었다. 또한 서비스교육의 재추천에는 상황평가(C)의 교육목표, 과정평가(P)의 상호작용, 교육지원, 산출평가(P)의 직무성과 요인이 긍정적인 요인으로 작용하였으며, 상황평가(C)의 요구진단은 부정적인 요인으로 영향을 미쳤다. 따라서 항공서비스교육의 만족도를 높이기 위해서는 인적자원이 아니라 교육의 목표, 상호작용, 프로그램관리, 성과를 높여야 하며, 서비스교육의 재추천을 위해서는 항공사의 요구진단보다는 교육목표, 상호작용, 교육지원, 직무성과를 높일 필요가 있음을 시사한다.

  • The COVID 19 pandemic has led to a new global recession and is still causing a lot of issues because of the delays in the employment of people. This scenario has severe consequences for many countries' labor markets in the world. This problem's complexity and importance requires an integrated method of subjective and objective evaluation rather than intuitive decisions. This research aims to investigate sustainable indexes for assessing the unemployment problem by using a Multi-Criteria Decision-Making Model (MCDM). Grey theory and Decision Making Trial and Evaluation Laboratory (GDEMATEL) are deployed to transform the experts' opinions into quantitative data. The analysis based on 20 crucial criteria is employed to determine the weights of sustainability of unemployment problems. The results revealed that the top ten of determinants are Economic growth, Industrialization, Foreign direct investment, Real GDP per capita, Education level, Trade Openness, Capacity Utilization Rate, Urbanization, Employability skills, Education system expansion, which have the most significant effects on the unemployment rate under COVID 19 impacts. Furthermore, GDEMATEL could effectively assess the sustainable indicators for unemployment problems in "deep and wide" aspects. The study proposes the Grey MCDM model, contributes to the literature, provides future research directions, and helps policymakers and researchers achieve the best solutions to the unemployment problems under "economic shocks."
