An attempt has been in this study to delineate the characteristics of spectral signatures of the vegetation in terms of various VIs, particularly made the Normalized Difference Vegetation Index(NDVI), Modified Soil Adjusted Vegetation Index2(MSAVI2) and Enhanced Vegetation Index(EVI). Multitemporal SPOT-4 VEGETATION data from 1998 to 2002 have been used for the analysis. They have been compared with each other for their similarities and differences. The correlations between the vegetation indices observed at various degree of vegetation coverage during their different stages of growth were examined. All of the VIs have shown qualitative relationships to variations in vegetation. Apparently, the NDVI and MSAVI2 are highly correlated for all of the temporal changes, representing the different stages of phenology.

The relationship between companies in the supply chain is a core competency of the company and key indicator which determines the survival of a company. Therefore, companies are investing in efforts for inter-company relations, and related studies have been conducted for a long time. However, in the supply chain, the positions and characteristics of suppliers and buyers are not the same. Therefore, research is needed to better understand and respond to other characteristics of the relationship between suppliers and buyers. The purpose of this study was to identify the characteristics of the resources held between the buyer and the supplier through social capital, which is a value asset that can be used as a resource created through social relations, and whether it affects the commitment of the relationship. In addition, The core of this study was to statistically analyze the differences between suppliers and buyers through this analysis. This study was conducted by surveying companies that are suppliers and buyers along the supply chain. The difference between the supplier and the buyer was revealed through empirical analysis, and statistically, the difference between the two groups was also revealed. As a result of the analysis, the higher the involvement of the buyer, the more significant the result of structural capital was, and the result was statistically opposite to the supplier. As for the relationship capital, quantitative and qualitative relationship capital had different effects on the commitment. Both the supplier and the buyer had a positive effect on relationship performance. However, the effect of emotional commitment on non-financial relationship performance has a greater degree of influence on suppliers, and it appears in statistical differences. This study revealed differences in the relationship between suppliers and buyers, and found that different investments and efforts were required for each group.

Purpose: This study examined the effects of peer assisted learning (PAL) using video recordings in standardized patients (SP) simulation. Methods: A mixed-method approach was adopted, in which quantitative data were supplemented with qualitative data. Research participants consisted of 49 nursing students, 24 of whom were assigned to the experimental group, and 25 to the control group. The 12 item instrument was used to measure perioperative care knowledge, while performance confidence was assessed with the 10 item questionnaire, and clinical critical thinking skills with the Clinical Critical Thinking Skill Test (CCTS). Qualitative data were collected using a reflective journaling and in-depth interviews. Results: Participants in the experimental group exhibited significantly higher levels of knowledge than those in the control group (t=5.43, p<.001), and were significantly more confident in their performances (F=52.33, p<.001). However, no significant differences were found between the experimental and the control groups with regard to CCTS (t=0.72, p=.477). A qualitative content analysis was conducted using the interview and reflective journaling data, in which six major themes were elicited from three codes. Conclusion: PAL employing video recordings is expected to be utilized as a teaching and learning strategy in simulation-based nursing practicum with greater frequency and longer period, given the positive effects observed in this study.

Objectives: This study aimed to identify the process of psychosocial assessment, the experience of intervention, and the improvement after the disaster that Danwon high school students survived from the sinking of the Motor Vessel (MV) Sewol in South Korea on April 16, 2014. Methods: We conducted in-depth qualitative research using individual interviews from January to February 2017. Twenty-one of 75 Danwon high school students survived by the MV Sewol disaster were studied. Two interviewers participated in the in-depth interview. Interviews were transcribed verbatim, coded, and analyzed through content analysis based on psychosocial assessment and intervention after the disaster. Results: Twenty-one participants were 20 years old, where 10 were male (47.62%), and 11 were female (52.38%). More than 75% of the interviewed students felt that mental health services were needed, and more than 85% required mental health assessments. Regarding psychiatric symptoms, the students reported that they suffered depression and insomnia (19.05%), anxiety (14.29%), nightmares and phobias (9.52%), and difficulties regarding concentration, aggression, and game addiction (4.76%). Conclusion: Despite survivors experiencing the same disaster, there were differences in their responses to mental health assessments and interventions experienced during the three years, and conflicting opinions were reported. In planning future evaluations and interventions, it is necessary for strategies to cope with flexibly to consider the characteristics and symptoms of the survivors while maintaining principles.

Purpose - As the global product network expands through both internationalization and diversification of the multimodal transportation system, corporate strategies have shifted to emphasize the importance of a high value-added international logistics system. To guide policies and strategies to attract relevant industries, this study aims to analyze the location competitiveness of regional logistics distribution center to serve Northeast Asia. Design/methodology - Multi-criteria techniques are considered to offer a promising framework for evaluating decision-making factors. This paper employed an analytic hierarchy process to analyze the hierarchal structure of determinants for selecting the location of a regional logistics distribution center. Adopting both qualitative and quantitative evaluations, this study suggest political implications for a regional logistics distribution center development, such as the direction of political support, service differentiation and infrastructure development. Findings - This study developed a location competitiveness evaluation model, based on the case study of the major port-cities in Northeast Asia. Evaluation model incorporates five factors underpinning 17 components extracted using factor analysis. The results revealed that the logistics factor is the most significant factor for evaluating the competitiveness of a regional logistics distribution center. The remaining factors were market, costs, and services environment. Comparing qualitative and quantitative evaluations, results provide useful insights for a regional logistics distribution center development in Northeast Asia. Originality/value - This study revealed differences between qualitative and quantitative evaluations. The finding implies that prior works on evaluation models of competitiveness has not successfully measured the gap between quantitative data and expert' evaluations. To overcome this limitation, this paper considered both actual data such as actual distance, cost, the number of companies located, and expert opinions.

Background: The evolving healthcare environment necessitates changes in pharmacy education to meet these demands, with problem-based learning (PBL) being a promising approach. Methods: This study employed a single-group, repeated-measures design to evaluate the effects of PBL on the communication and problem-solving skills of fifth-year pharmacy students at S University. The course, which focused on pharmacy practice and communication, included 36 students who participated in structured pre- and post-intervention surveys, as well as self-reflection journals. The primary competencies assessed were problem-solving and communication skills. Data collection involved quantitative measures through surveys and qualitative insights from self-reflection notes. Results: Of the 36 students, 35 completed the pre-intervention surveys, and 27 completed the post-intervention assessments. Significant improvements were observed in problem-solving skills, including problem identification, information gathering, and planning. Communication skills showed overall improvement, though the differences were not statistically significant. Qualitative analysis of self-reflection notes revealed enhanced understanding of elderly patient care, increased responsibility, teamwork, and the importance of effective communication in pharmacy practice. Commonly identified themes included a heightened sense of responsibility, the importance of teamwork, and an appreciation for the multifaceted nature of pharmacy practice in elderly care. Conclusion: The PBL approach effectively enhanced students' problem-solving abilities and provided valuable experiential learning in pharmacy practice. The qualitative data indicated that students gained a deeper understanding of their roles and responsibilities, fostering greater motivation and teamwork. Further research should focus on broader applications across different institutions to validate these findings.

This paper considers Japanese political interviews to integrate conversation and facial expression analysis. The behaviors of political leaders will be disclosed by analyzing questions and responses by using the turn-taking system in conversation analysis. Additionally, audiences who cannot understand verbal expressions alone will understand the psychology of political leaders by analyzing their facial expressions. Integral analyses promote understanding of the types of facial and verbal expressions of politicians and their effect on public opinion. Politicians have unique techniques to convince people. If people do not know these techniques and ways of various expressions, they will become confused, and politics may fall into populism as a result. To avoid this, a complete understanding of verbal and non-verbal behaviors is needed. This paper presents two analyses. The first analysis is a qualitative analysis that deals with Prime Minister Shinzō Abe and shows that differences between words and happy facial expressions occur. That result indicates that Abe expresses disgusted facial expressions when faced with the same question from an interviewer. The second is a quantitative multiple regression analysis where the dependent variables are six facial expressions: happy, sad, angry, surprised, scared, and disgusted. The independent variable is when politicians have a threat to face. Political interviews that directly inform audiences are used as a tool by politicians. Those interviews play an important role in modelling public opinion. The audience watches political interviews, and these mold support to the party. Watching political interviews contributes to the decision to support the political party when they vote in a coming election.

The purpose of this study is to analyze the effectiveness of a host family experience program on the adaptive behavior and self-management skills of children with severe disabilities and to suggest its applicability into clinical practice. The investigators developed a host family experience program and researched the pre-test and post-test designs with nonequivalent groups. The experiment and comparison groups were comprised of 34 children with severe disabilities that lived at S, a care facility for the severely disabled. They were examined for the program's effects on them before and after the application. After analyzing 17 cases for differences in the subjects' quantitative scores, a qualitative analysis was carried out on one representative case. The quantitative analysis results reveal that the experiment group showed a significant increase in their scores of adaptive behavior and self-management skills compared to the comparison group. Positive changes were also observed among the former group in the qualitative analysis. Thus the host family experience program was effective in improving the adaptive behavior and self-management skills of the children with severe disabilities at the facility. These findings indicate that the host family experience program played a positive role in enhancing the adaptive behavior and self-management skills of the children with severe disabilities at the facility and that such host family experience programs should be applied and reinforced in the field of social welfare practice.

Objectives: The importance of MSDS is emphasized for communicating hazardous information due to the increase in the types and usage of chemical substances. The purpose of this study is to assess the reliability of MSDS by collecting and examining paint thinners commercially available in South Korea. Methods: Twenty-five paint thinners were purchased at paint stores and the provision of MSDS was checked. Quantitative and qualitative analysis was performed on the chemical constituents of the thinners using GC-MSD and GC-FID. Reliability was evaluated by the MSDS collection rate for the paint thinners and calculating the rate of matching between laboratory analysis results and the contents and composition of chemical constituents given in the MSDS. Results: Unlike a study conducted in 2006, MSDS were provided for all 25 thinners. As a result of qualitative analysis using GC-MSD, 104 chemical substances were detected. The substances with the highest detection rate were identified in the order of toluene, butyl acetate, acetone, xylene, and ethyl benzene. A component matching rate of 41% was found by comparing the differences between the number of substances detected in laboratory testing and the number of substances listed in the MSDS. Benzene, a carcinogen not listed in the MSDS, was detected in two thinners produced by a small company. The detected benzene contents were 0.039 and 0.040%. When benzene is used, it should be strictly handled according to the Industrial Safety and Health Act. However, since it is not listed on the MSDS, it is judged that benzene was not being managed as a carcinogen in the workplaces where it is used. Conclusions: Since the reliability of MSDS, which play an important role in hazard communication, was evaluated to be low, it is necessary to systematically and continuously secure this reliability. In particular, carcinogens should be managed more strictly.
