A paradigm shift in the government's energy policy was reflected in its declaration of early closure of old nuclear plants as well as cancellation of plans for the construction of new plants. To this end, unit 1 of Kori Nuclear Power Plant was permanently shut down and is set for decommission. Based on these changes, the off-site transport of spent fuels from nuclear power plants has become a critical issue. The purpose of this study is to develop an optimized method for transportation of spent fuels from Kori Nuclear Power Plant's units 1, 2, 3, and 4 to an assumed interim storage facility by simulating the scenarios using the Flexsim software, which is widely used in logistics and manufacturing applications. The results of the simulation suggest that the optimized transport methods may contribute to the development of delivery schedule of spent fuels in the near future. Furthermore, these methods can be applied to decommissioning plan of nuclear power plants.

Franchise store retailing is taking on ever greater roles in business and commerce in China. The diverse product range, small-batch order, high frequency and time-specific requirements inherent in retail logistics make it the most complicated of all categories of logistics. In franchise store retailing, expanding business scales make trans-regional development a trend. Without a well-functioning logistic system, the standardized delivery of products would be held back, impacting trans-regional development strategy and operational costs. Therefore, the efficiency of franchise store retailing largely depends on logistical efficiency. The integrated and streamlined management of franchise stores depends in large measure on their logistical centers. As such, logistical centers constitute the key link and bears on core competitiveness in franchise store retailing. This thesis begins with an analysis of the current developments and four basic logistical models of franchise store retailing in China, proceeds to summarize developmental trends as well as focal issues and proposes an efficiency enhancing plan.

Purpose: This study aimed to identify the general characteristics and health behaviors of students with non-therapeutic substance use. Methods: This secondary data analysis used data from the 17th Korea Youth Risk Behavior Web-based Survey (2021). Analyses of the 54,848 adolescents used descriptive statisics, the Rao-Scott χ² test, and logistic regression. Results: The risk factors for substance use among students were anxiety, loneliness, living separately from family, suicidal ideation, e-cigarette use, and high stress. Conclusion: The findings help identify the risk factors for non-therapeutic drug use among adolescents. Since South Korea does not have a drug prevention program for its adolescent population, an educational plan based on these findings could help prevent adolescent substance abuse.

본 연구는 그 동안 한국에서 시행되고 있는 저출산 관련 주요 정책의 효과성에 대한 분석을 시도하고자 한다. 이를 위해 저출산 관련 시책에 대한 인지도와 경험도를 검토하였으며, 이러한 인지도와 경험도가 자녀의 출산계획에 미치는 영향을 분석하였다. 분석 결과 현존 자녀수를 고려하지 않을 경우 경제적 지원 정책과 양성평등 문화조성에 대한 인지도는 출산계획의 가능성을 높이는 것으로 나타났다. 그러나 이러한 결과는 현존 자녀수별로 분석할 경우 다르게 나타난다. 즉 무자녀 기혼여성들의 경우 저출산 관련 대책들에 따른 자녀출산계획의 차이는 없는 것으로 나타난다. 1자녀 기혼여성의 저출산 관련 지원정책에 대한 인지도가 추가출산계획에 미치는 영향도 모두 통계적으로 유의하지 않은 것으로 나타난다. 2자녀 여성의 경우에도, 저출산 정책에 대한 인지도가 추가출산계획에 미치는 영향은 유의하지 않은 것으로 나타났다. 이러한 결과는 저출산 정책의 이용도의 경우에도 동일한 패턴으로 나타난다. 즉 현존 자녀수를 고려하지 않을 경우 경제적 지원, 일 가정 양립 지원, 양성평등 문화조성 등은 출산계획에 통계적으로 유의한 영향을 주는 것으로 나타난다, 그러나 현존 자녀수별로 분석을 진행할 경우 이러한 변수들의 통계적인 유의성은 사라져 저출산 정책의 이용경험은 모두 출산계획에 유의한 영향을 주지 않는 것으로 나타났다. 이러한 결과는 저출산 정책을 수리할 때 자녀수에 대한 고려가 필수적임을 보여주는 것이다. 이와 함께 저출산 관련 지원정책의 효과가 뚜렷하게 나타나기 위해서는 보다 실질적이고 체계적인 저출산 대책이 지속적으로 추진되어야 한다는 점을 반영한 것으로 보인다.

Objective: To determine the impact of dedicated subspecialized radiologists in multidisciplinary team (MDT) discussions on the management of lower gastrointestinal (GI) tract malignancies. Materials and Methods: We retrospectively analyzed the data of 244 patients (mean age ± standard deviation, 61.7 ± 11.9 years) referred to MDT discussions 249 times (i.e., 249 cases, as five patients were discussed twice for different issues) for lower GI tract malignancy including colorectal cancer, small bowel cancer, GI stromal tumor, and GI neuroendocrine tumor between April 2018 and June 2021 in a prospective database. Before the MDT discussions, dedicated GI radiologists reviewed all imaging studies again besides routine clinical reading. The referring clinician's initial diagnosis, initial treatment plan, change in radiologic interpretation compared with the initial radiology report, and the MDT's consensus recommendations for treatment were collected and compared. Factors associated with changes in treatment plans and the implementation of MDT decisions were analyzed. Results: Of the 249 cases, radiologic interpretation was changed in 73 cases (29.3%) after a review by dedicated GI radiologists, with 78.1% (57/73) resulting in changes in the treatment plan. The treatment plan was changed in 92 cases (36.9%), and the rate of change in the treatment plan was significantly higher in cases with changes in radiologic interpretation than in those without (78.1% [57/73] vs. 19.9% [35/176], p < 0.001). Follow-up records of patients showed that 91.2% (227/249) of MDT recommendations for treatment were implemented. Multiple logistic regression analysis revealed that the nonsurgical approach (vs. surgical approach) decided through MDT discussion was a significant factor for patients being managed differently than the MDT recommendations (odds ratio, 4.48; p = 0.017). Conclusion: MDT discussion involving additional review of radiology examinations by dedicated GI radiologists resulted in a change in the treatment plan in 36.9% of cases. Changes in treatment plans were significantly associated with changes in radiologic interpretation.

Background: Assessment of supportive needs is the requirement to plan any supportive care program for cancer patients. There is no evidence about supportive care needs of Iranian breast cancer patients. So, the aims of present study were to investigate this question and s predictive factors. Materials and Methods: A descriptive-correlational study was conducted, followed by logistic regression analyses. The Supportive Care Needs Survey was completed by 136 breast cancer patients residing in Iran following their initial treatment. This assessed needs in five domains: psychological, health system and information, physical and daily living, patient care and support, and sexuality. Results: Patient perceived needs were highest in the health systems and information (71%), and physical and daily living (68%) domains. Logistic regression modeling revealed that younger participants have more un-met needs in all domains and those with more children reported fewer un-met needs in patient care and support domains. In addition, married women had more un-met supportive care needs related to sexuality. Conclusions: The high rate of un-met supportive care needs in all domains suggests that supportive care services are desperately required for breast cancer patients in Iran. Moreover, services that address informational needs and physical and daily living needs ought to be the priority, with particular attention paid to younger women. Further research is clearly needed to fully understand supportive care needs in this cultural context.

The purposes of this study were to investigate the eating of breakfast by female middle school students in Seoul, the perception of the school breakfast program (SBP), and determine the factors affecting the intention to participate in SBP. Out of 340 questionnaires distributed to the female middle school students, 334 were returned (98.2% response rate) and 323 were analyzed. The subjects were categorized into two groups by the intention to participate in SBP. Subjects were classified as participating and non participating groups. As a result of analyzing the breakfast intake frequency, 'hardly eat' showed the highest with 18.5% in the participating group and 10.3% in non participating group, while 'eat every day' showed 38.2% in the participating group, and the highest with 65.5% in non participating group (p<0.001). For the reason for skipping breakfast, 'no time' showed the highest with 30.0% in the participating group, 'over sleep' and 'no appetite' showed the highest with 24.8% in non participating group. For the reason for not participating in SBP, 'breakfast should be eaten at home' showed the highest with 47.2% in non participating group and 'may get up early in the morning' showed the highest with 46.2% in participating group (p<0.01). To determine the factors affecting the intention to participate in SBP, logistic regression analyses were conducted for female middle school students. According to the logistic regression analysis, father's education level was independently associated with the intention to participate in SBP in female middle school students [Odds Ratios (OR) 2.38, 95% Confidence Interval (CI) 1.03~5.52]. Frequency of eating breakfast on weekdays (OR 1.36, 95% CI 1.01~1.81), Level of need for school breakfast (OR 0.52, 95% CI 0.35~0.76) and whether to approve school breakfast (OR 0.27, 95% CI 0.18~0.41) were independently associated with the intention to participate in SBP in female middle school students. In conclusion, proper educational efforts for importance of school breakfast could be useful plan to develop school breakfast program.

The information technology(IT) development of telecommunication, along with the informationalization over the world, enables the firms to process their inner and outer operations through Electronic Data Interchange (EDI) system. And the concept of logistics has become more important to the enterprises in strategic sense because it had aggrandized itself to more comprehensive and integrative concept. Also the world shipping market is more competitive than any other market. In these environment, to maintain competitve power, shipping firms process operations by Logistics Information system(LIS), And then, reduce the working processes, working time and its costs. So the LIS has become more important in developing our national logistics system and industry. Therefore, this study purposes on empirically analyzing the activation factors of shipping LIS and the relationship these factors with logistic performances in the shipping industry. Considering environments of Shipping logistics information system, this study sets up the research model and hypothesis to examine the activation factors of shipping LIS and the relationship these factors with logistic performances. We used the field data on the 163 numbers of firms(29 overseas shipping companies and 133 forwarding Agency) to get the empirical evidence. According to the study results, The shipping LIS activation factors which the sample firms recognized as important: were top manager's support, well structured communication channel, strategic plan's connection and inner informationalization level. And IS organization ＆ human resources, IS discipline ＆ training, software development, IS organizational alignment, database management system, information standardization, competitive advantage, financial support and government support represent partially significant. Also, the current shipping LIS's main problems are expensive system cost, standardization of working process's, institution's imperfection and system's interaction defect. So these problems must be improved to activate shipping LIS.

Background: The purpose of this study is to investigate association between harms from the alcohol consumption of others and depression measured by Patient Health Questionnaire-9, perceived stress among Korean adults. Methods: This study used data from the 7th Korea National Health and Nutrition Examination Survey (2016-2018; n=9,668). We used multivariate survey logistic regression analysis in order to investigate the association. Results: Among participants, 5.55% had experience for harms from the alcohol consumption of others. Among them, 15.25% had depression and 8.97% had perceived stress. Multivariate survey logistic regressions revealed that objective depression and perceived stress were associated with harms from the alcohol consumption of others (objective depression: odds ratio [OR], 3.30; 95% confidence interval [CI], 2.32-4.70; perceived stress: OR, 2.04; 95% CI, 1.62-2.56). Conclusion: Objective depression and perceived stress was significantly associated with harms from the alcohol consumption of others. This study suggests that government agencies and policy makers should recognize current status, further, develop a plan to identify the causes of harms from the alcohol consumption of others and protect vulnerable groups.
