This study introduces an effective method for predicting individual local tax delinquencies using prevalent machine learning and deep learning algorithms. The evaluation of credit risk holds great significance in the financial realm, impacting both companies and individuals. While credit risk prediction has been explored using statistical and machine learning techniques, their application to tax arrears prediction remains underexplored. We forecast individual local tax defaults in Republic of Korea using machine and deep learning algorithms, including convolutional neural networks (CNN), long short-term memory (LSTM), and sequence-to-sequence (seq2seq). Our model incorporates diverse credit and public information like loan history, delinquency records, credit card usage, and public taxation data, offering richer insights than prior studies. The results highlight the superior predictive accuracy of the CNN model. Anticipating local tax arrears more effectively could lead to efficient allocation of administrative resources. By leveraging advanced machine learning, this research offers a promising avenue for refining tax collection strategies and resource management.

The research assesses the impact of a digital procurement (e-purjee) system for sugarcane growers in Bangladesh. The system itself is simple, transmitting purchase orders to local farmers via SMS text notification. It replaces a traditional paper-based system fraught with low reliability and delivery delays. Applying expected value theory, and using decision tree representations to depict growers' decision-making complexity in an information-asymmetric environment, we compute outcomes for the strategies and sub-strategies of ICT vs. traditional paper-based order management from the sugarcane growers' perspective. The study results show that the digital procurement system outperforms the paper-based system by tangibly reducing growers' economic losses. The digital system also appears to benefit growers non-monetarily, because of reduced uncertainty and a higher level of perceived fairness. Sugarcane growers appear to value the non-monetary benefits even higher than the economic advantages of the e-purjee system.

This paper presents the empirical research results conducted in a Swedish care organization for elderly and handicapped. The objective of the research was to empirically assess the implementation and practices of a quality system (ISO 9000) from an organizational change and development perspective. The empirical data were collected through multiple methods; interviews were carried out with key-persons and leadership in the organisation and surveys were conducted to all employees. Interactive methods have been applied to various groups in the organisations e.g., directors, supervisors, and the leadership of the quality project and the local politicians. The empirical findings indicate, among others, that the implementation processes were received and perceived differently in the different parts of the care organisation due to different leadership strategies and employee involvement policies. Other critical factors such as acceptance, resistance, motivation, commitment, the role of leadership, learning possibility, etc. have also been investigated, analysed and discussed. Finally some recommendations on how to approach organisational change as well as strategies for implementing a quality system in the care sector are presented.

This paper stems from information accumulated from extensive literature review, a pilot study and a formal interview for an ongoing research on housing privatization implemented by the government-linked companies in Malaysia. Through extensive literature review, issues pertaining to housing privatisation were identified. Expectations of public sector, outcome of housing privatisation and factors influencing such outcome have also been tentatively confirmed through pilot study and an ongoing postal survey. A formal interview with a project director of independent Public-private partnerships (PPP) organization in UK has also inspired some useful lessons for the local housing industry. Different modalities of PPP from various countries show that while housing privatization pose several problems, mitigating them is possible through appropriate strategies.

SWOT model was used to develop strategies for the Korean construction firms in entering the global construction market. Literature review, official statistics survey and other research methods were utilized in order to extract internal and external environmental factors of both the firm and local area. By extracting strength, weakness, opportunity and threat factors, a total of 12 strategies were produced: SO (Strengths-Opportunities), ST (Strengths-Threats), WT (Weaknesses-Threats), and WO (Weaknesses-Opportunities). The result of the study can be utilized as a basic data in developing a strategy for the Korean construction firms to penetrate into the global construction market.

빅데이터의 가치가 인식되고 정부 3.0이 발표되면서 빅데이터에 대한 관심이 증가하고 있다. 그러나 각 부처나 지방자치단체에 구체적인 추진 대안이나 전략이 취약한 상황에서 빅데이터를 체계적으로 활용하고 성과를 낸다는 것은 그리 쉬운 일이 아닐 것이다. 이에 본 연구는 지방자치단체의 빅데이터 활용 영역을 정리한 다음, 빅데이터 활용 전략을 제안하고자 하였다. 연구 결과 지방행정의 빅데이터 활용 영역은 크게 이상 현상 감지 및 대응, 가까운 미래 예측 및 대응, 분석된 상황 대응 및 새로운 정책(행정 서비스) 개발, 시민 맞춤형 서비스 등 네 가지로 구분되었다. 또한 빅데이터 활용 전략은 단계적 접근, 사용자의 요구분석, 주요성공요소 기반 추진, 시범사업, 성과평가, 성과에 따른 인센티브, 공통기반 구축 등으로 정리하였다.

Objectives: The objective of the present study was to investigate whether gender mederates the mediating effect of job burnout on the relationship between role stress and depression among medical doctors in Local clinics in South Korea. Methods: Questionnaires that assess role stress, job burnout, and depression were administered to. 265 medical doctors who worke in local clinics in Seoul, Busan, Daejeon, and Gyeonggi provinces. Data analysis was conducted using the PROCESS macro in Statistical Package for the Social Sciences(SPSS). Results: Job burnout mediated the relationship between role stress and depression. Further, gender moderated the relationship between role stress and job burnout. Finally, gender moderated the mediating effect of job burnout on the relationship between role stress and depression. Conclusions: On the basis of the emergent findings, effective coping strategies that can alleviate role stress are articulated. However, the findings also suggest that the selection of a suitable intervention must be based on the gender of the medical doctor.

The study focused on the evaluation of maintenance management strategies used in public hospital buildings in Lagos state. It also assessed the labour composition for maintenance operations. In achieving these objectives, opinions of maintenance officers of ten (10) different hospitals in different local government areas of the state were sampled through well structured questionnaires. The data collected were analyzed using descriptive and inferential statistics. From the analysis, the study revealed that majority of those public hospitals do not have specific budget for maintenance programmes, maintenance policies, maintenance log book and maintenance manual to guide the operatives. About 98% of them do not understand the type of maintenance strategy being used for their maintenance operations. 78% of the maintenance work are only executed when there is a breakdown or in response to user's request. For labour composition, the cleaning of interior and exterior of the building, inspection of building elements, repairs and replacements of building elements are mainly carried out by in-house staff, while the repair and replacement of equipment is by outsourcing. The study also revealed that using in- house staff, reduces costs and provides a higher security while outsourcing provides more flexibility in staffing reduces equipment expenditures and provide better access to special skills. The study recommended proactive measures to provide necessary training and support for maintenance staff and users of these facilities and a means of securing sufficient funds for maintenance programmes.

전 지구적인 문제로 부상하고 있는 생물다양성 훼손에 대처하기 위하여 여러 국가에서 국가생물 다양성전략 및 지역차원에서의 실천을 위한 지역생물다양성전략을 수립하고 있다. 본 연구에서는 국내 8개 지역과 국외 41개 지역에서 수립된 지역생물다양성전략을 언어네트워크분석법을 이용하여 국내 외 전략수립 특성을 파악하였다. 연구결과 지역생물다양성전략에 있어서 국내와 국외의 차이가 있음을 보여주었는데, 보전과 관리가 국내 외에서 가장 많이 사용된 핵심어로 나타났으나 비전, 목표부문, 전략부문, 실천과제 등 각 전략체계에서 우선적으로 사용된 핵심어들은 다소 다른 것으로 나타났다. 네트워크 분석 결과 국내가 국외와 비교하여 더 세분화된 분산형 네트워크를 가지고 있는 것에 반해, 국외의 경우 좀 더 포괄적이고 통합적으로 구성된 밀집형의 네트워크를 가진 것을 알 수 있었다. 이러한 지역생물다양성전략의 차이는 생물다양성의 위협요인이나 문제인식 혹은 지역상황의 차이 등에 의한 것으로 판단된다. 본 연구결과는 향후 국내 지역생물다양성전략의 수립이나 생물다양성협약의 비전을 달성하기 위한 지역적 역할을 평가하는데 도움이 될 수 있을 것으로 기대된다.
