The Effect of Employee Training and Compensation on Ground Staffs Job Performance in Airline Industry

Chesda Kong Graduate School Korea Aerospace University 2022 국내석사

The airline industry refers to organizations that provide air transport services to paying customers. The airline industry is also known as a “passenger business”. Both flight crew and ground staff's organizations underperform, still deliver insufficient services, and provide limited facilities compared to similar businesses in the same field. This can have a negative impact on the airline industry and its performance. Potentially, HRM contributes to employee work performance in the airline. The performance of ground staffs in airline industry can be judged or measured by their friendliness, their attentiveness, their attitudes, their appearances, and the way they implement and perform their assigned tasks. Most of the respondents feel that their airlines create the conditions through which they are motivated to work harder. The airline industry recognizes the value of training in relation to their work performed. The major factor that brings about high level of job motivation and performance is salary.

A Filter Approach of Feature Selection and its applications for Mass Spectrum Data

트렁니아 korea Aerospace university graduate school 2008 국내석사

Recently, new methods based on mass spectrometry such as SELDI-TOF MS (surface-enhanced laser desorption / ionization time-of-flight mass spectrum) are emerging as an alternative to traditional methods in disease diagnosis and biomarker identification. However, feature selection methods need to be used to solve the “curse of dimensionality” before classification algorithms could be applied. In this thesis, we proposed a new filter method of feature selection for SELDI-TOF MS datasets. In the method, the relevance value of a feature representing how well the value of a feature helps to separate a sample from a given class was defined based on the difference between the numbers of samples in the given class with greater and less feature value than the sample. Using the relevance value as a basic factor, several ranked feature lists were established. Searching strategies find out optimal feature sets by utilizing the relevance indices of features without using learning algorithms. The proposed method can deal with not only two-class but also multiple-class problems. The experiments were applied to clinical datasets from NCI/CCR and FDA/CBER Clinical Proteomics Program Databank: Ovarian 4-3-02, Ovarian 8-7-02, two-class Prostate and four-class Prostate cancer datasets. The results suggested that the proposed relevance index was comparable to conventional methods using top ranked features for classification; and the optimal feature sets found by proposed searching algorithms were apparently more effective than top ranked features.

ESTIMATION OF PRACTICAL CAPACITY FOR ENTEBBE TMA USING A MICROSCOPIC SIMULATION MODEL

Eva Luyiga The Graduate School Korea Aerospace University 2022 국내석사

Air traffic management (ATM) generally capitalizes on achieving a safer, more efficient, and a more economical air traffic system. Worldwide, the current airspace has become increasingly constrained due to the increase in air traffic demand and the Entebbe airspace is no exception. The trend shows a resilient growth and recovery from pandemic effects and other mishaps in the travel industry. This automatically triggers an increase in delays and congestion in the airspace and at airports as well, leading to a complexity within the Terminal Control Area (TMA); a very critical part of the airspace where traffic climb through after departure and where they descend through, as they approach to land. The air traffic controller (ATC) and the physical system resources, such as the airspace, are the two fundamental components of air traffic resources. The basis and cornerstone of ensuring the safety and effectiveness of air traffic management systems is a reasonable appraisal and effective management of ATC and airspace resources. Many large airports are considering ground infrastructure and operational improvements to boost capacity and safety while reducing delays caused by growing throughput demand. The step to reduce delays in aviation is a very important one as it reduces on company losses, improves customer satisfaction and the entire level of service quality enhanced. Many studies have been done on delay management within various TMAs. This study focuses on determining the practical capacity of the Entebbe TMA by using Total Airspace and Airport Modeler (TAAM) simulation model and using delay as the performance parameter that is used to derive the value of practical capacity by using statistical analysis. The first step was to retrieve a previously used traffic schedule from the AMS and then a fast-time simulation model built using the available STARs and SIDs within the TMA, and then the simulation was run, increase in traffic was done and delay data collected. The analysis was done using Microsoft excel and the practical capacity hence determined. The total delay was modelled using a regression model. The findings of the model present a statistical approach for airspace designers and air traffic flow planners. Keywords: Airspace, TMA, Capacity, TAAM, Delay, STARs, Demand, SIDs

Celestino Obiang NGUEMA BINDANG The Graduate School Korea Aerospace University 2022 국내석사

This research material is about identifying valuables Airports Profitability Improvement Strategies for Developing Countries, through their constraints, weaknesses, strengths and opportunities recognitions, particularly, the Bata International Airport profitability improvement in Equatorial Guinea. Aviation sector provides the only worldwide transportation network, which makes it essential for global business and tourism. It plays a vital role in facilitating economic growth, particularly in Developing Countries. The sector is considered one of the world’s most important industries. Its development, technical and service achievements make it one of the greatest contributors to the advancement of modern society (Air Transport Action Group ATAG-2005). Due to their importance and direct implication in the aviation industry activities, Airports as other actors need to suffer massive and deep metamorphosis to meet the actual era´s demands and requirements, as to answer the needs of passengers, airlines and other customers’ behaviors, in which the world is directed to digital transformation of the sectors, characterized by new challenges in term of innovations and integrations. Based on information gathered from Bata International Airport (BSG) in Equatorial Guinea and other Developing Countries airports, and knowing the difficulties existing in most of those countries, in which one of the industries that still need to be addressed by all means is the aviation one, due to its poor technology, bad conditions of airport infrastructures, low or null compliance of international aviation Standards and Recommendation Practices (SARPS), limitations in human resources and their capacitation, national airlines poor management and their international market weakest integration, etc., but mostly the lack of good governance, specifically the non-sector accorded importance from their respective governments. All these leads the industry to remain unprofitable and expect governments implications economically for the airports sustainability. Knowing that Developing Countries haves a high potential growth in population, businesses and thus the future of air transportation, our objective is to shift this actual trend by learning from other countries successful development experience models, and suggest specific actions and strategies, adapted to Developing Countries Different contexts for their aviation profitability, and so contribute in their national economic sustainable growth. Three Cases Studies from different countries have been done in other to come out with the proposed strategies, Incheon International Airport (ICN) from South Korea, Singapore International Airport (SIN) and Hong Kong International Airport (HKIA). Those were chosen due to their time record rapid growth. At some point in the past, they were just or worst like many developing countries now days, but because of the good governance, commitment, determination, future vision, mission and value creation for their citizens, they could come out with strong decisions and smart forward move, as to set-up their sustainable development strategies, from which, other countries can have an insight learning experience for their success. From those cases studies, we came out with 12 strategies, divided in 3 categories, which are being suggested to Developing Countries for their development plans set-up, most particularly the aviation profitability improvement plans. It should be under everybody’s interest to have Developing Countries’ air transport in good conditions, specifically airports, for their Efficiency, Self-Sustainability, Secure and Safe, with Innovative Technologies and High Quality Human Resources, so that they can meet the actual sector profitability global trend requirements. In this case, all together will achieve a good air transport system that contribute in those countries sustainable growth and in air transport safe and secured Globalization and Liberalization.

In this 4th industrial revolution, the aviation industry become one of the potential contributors for elevating the country’s economy through its supply chain activities since deregulation policy was implemented. For which the aviation sector can stimulate other related industries to grow and provide jobs, increasing productivity, enhancing the living standard, and eventually alleviating extreme poverty. After a long-struggling from Portuguese colonial and Indonesia’s occupation. Finally, Timor-Leste claimed its independence in May 2002. However, infrastructure and services in the aviation industry remain challenged since the restoration of the independence. The essential objective for conducting this research is to recognize and discuss the determinant factors that can impact the aviation-related industry in a developing country, especially for Timor-Leste. As many countries considered the air transport industry can stimulate other sectors like tourism and agriculture sector to contribute boosting country’s economy. For the purpose mentioned, the researcher uses the case study method by comparing the strategic implications that impact aviation-related industries. By using Michael E. Porter’s Diamond Model to identify and analyze in-depth the strategic implications from selected benchmarking countries like Singapore, Malaysia, and Indonesia. Those benchmarking countries were selected based on their historical background, geographical location, demographic, governance, economic, and air transport infrastructures, which referred to the Porter’s Diamond Model. After identifying, comparing, and in-depth analysis, the most determinant strategic implications that impact the competitive advantage of the nation based on the Porter’s Diamond model consist of (1). Role of Governance, which is referred to the Government policy and leadership of the ruling man in the country which has and can be influenced in all determinant factors, followed by (2). Factor condition which referred to competence and availability of human resources, physical infrastructure, and capital resources. (3). Related Supporting industries like Agriculture sector, manufacture sector, tourism industry (4). Firm strategy structure and rivalry referred to how the firm establish, managing, and competes for its rivalry, (5). Availability of the demand or users of the product and (6). Role of chance which is referred to the creation and entrepreneurship of a new product and an especial event that transform a firm. To sum up, the researcher concluded that, among the determinant factors for the competitive advantage of the nation, the government role is highly considered especially in developing countries like Timor-Leste as the government policy and leadership strategies mostly influence all other determinants factors. Additionally, the competitive advantage is based on the human competences on choosing the right strategy for managing and transforming its limited resources for the benefit of the people.

Porter의 다이아몬드 모델을 활용하여 싱가포르, 말레이시아 및 인도네시아와 공항산업을 벤치마킹하여 그 전략적 시사점을 도출하였다. 벤치마킹은 Porter의 다이아몬드 모델을 적용하기에 적합한 국가를 선정해서 진행했다. 역사적 배경, 지리적 위치, 인구 통계, 거버넌스, 경제 및 항공 운송 인프라를 분석하였다. Porter's Diamond 모델을 기반으로 국가의 경쟁 우위에 영향을 미치는 가장 결정적인 전략적 시사점은 식별, 비교 및 심층 분석의 프로세스이다. 국가경쟁력에 영향을 미치는 (1) 국가의 인적요인, (2) 물리적 기반 시설 및 자본 자원의 능력 및 가용성을 언급하는 요인 조건, (3) 농업 부문, 제조 부문, 관광 산업과 같은 관련 지원 산업, (4) 기업 전략 구조 및 기업이 경쟁을 위해 경쟁하는 방법, (5) 제품 수요 또는 사용자의 가용성, (6) 기회의 역할 및 새로운 제품의 창조와 기업가 정신 등으로 구성되고 운도 영향을 미친다. 분석결과 국가의 경쟁력을 결정하는 요인 중 정부의 정책과 리더십 전략이 다른 모든 결정요인 보다 우선한다는 것이다. 특히 동티모르와 같은 개발도상국에서는 정부의 역할이 더더욱 중요하다. 나아가 경쟁력을 결정하는 것은 궁극적으로 사람이기 때문에 적합한 인재를 육성하는 것이 무엇보다도 중요하다. 키워드: 경쟁 우위, 다이아몬드 모델, 전략 시사점, 기술 및 혁신, 거버넌스 및 리더십, 요소 부여, 산업 혁명, 항공 운송, 인적 자원, 인프라 개발, 수요 공급, 동맹 및 경쟁, 투자

INFORMATION MANAGEMENT IN TRAJECTORY BASED OPERATIONS: ASSESSING THE GAP IN GHANA'S AIR TRAFFIC MANAGEMENT SYSTEM

Esther Teimle Moncar-Obeng The Graduate School Korea Aerospace University 2022 국내석사

Four-dimensional trajectory-based operations, data communications, performance-based navigation have been pegged as the ATM systems of the future and currently the focus for active research in developed countries. As ATM systems of the future, global acceptance and standardization implies a change in requirements for support systems. Information is a valuable resource in ATM, connecting all components and collaborators of the ATM system. Its management is critical to the functionality of the system and the ability of ATM information management to evolve in tandem with the ATM system will form the technological basis for the deployment of future ATM concepts. It has been observed by the researcher however that, both ATM and support system development is concentrated in developed nations with little to no contribution from developing nations who must embrace such developments once global standardization is attained. It happens that implementation within such systems is done in an unstructured manner leading to technical inefficiencies which affect global output. The study therefore sought to seek out the gaps in ATM information management in a developing nation and make recommendations for breaching the gaps in terms of attaining the idealized information management system for one future ATM concept that is trajectory-based operations. The study analysed three information management enablers: people, process and technology using the task-technology fit theory and gap analysis tools. The study found that people and technology were significant influencers of performance in the ATM and recommendations were made to improve these variables as well as develop a research culture within the system. Keywords Information, information management, trajectory-based operations, air traffic management, conformance gap.

THE IMPACT OF LOCUS CONTROL ON WORKPLACE STRESS AND JOB SATISFACTION: THE CASE OF THE PERSONNEL AT THE CAMEROON CIVIL AVIATION AUTHORITY (CCAA).

AGBORSONG MBIWAN The Graduate School Korea Aerospace University 2022 국내석사

The purpose of this paper is to examine the relationships between locus of control and the work related behavioural measures of job stress and job satisfaction on the Personnel at the Cameroon Civil Aviation Authority (CCAA). The objectives are to assess how locus of control impacts individuals and behaviour in the workplace in three primary areas: job stress, job satisfaction and may be job performance; to identify and analyse the effect locus of control has on the personnel at the Cameroon Civil Aviation Authority (CCAA) and; to propose possible solutions to address stress issues in the working environment. The questionnaires workplace stress survey’, ‘job satisfaction survey’ and ‘work locus of control scale’ were adopted from Paul E. Spector and The American Institute of Stress respectively for the study. These questionnaires were distributed to seventy-five (75) personnel at the CCAA both at the head office and at the airports: out of the seventy-five (75) expected responses, only fifty-four (54) responses were received. T-test statistics were used to determine if there is a significant difference of locus of control, job satisfaction and stress in male and female. In addition, A Pearson product-moment correlation coefficient was also used to examine the association between locus of control, job satisfaction and stress. Therefore, according to the t-test, only the difference between male and female respondents concerning job satisfaction found to be statistically significant. And according to A Pearson product-moment correlation a strong negative correlation was observed between work locus of control and job satisfaction as well as between workplace stress and job satisfaction. Whereas, a strong positive correlation was observed between work locus of control and workplace stress. With these, one would realize that locus of control affects workplace stress and job satisfaction at the Cameroon Civil Aviation Authority (CCAA); as individuals with a higher locus of control exhibit a higher workplace stress; also individuals with a higher locus of control showed less job satisfaction; individuals with a higher workplace stress displayed a low job satisfaction. Conclusively, it would be important for the management of the CCAA to improve on the working conditions so as to help workers to easily adapt at work: such can be done by having clear and defined goals, also by giving employees rooms to develop their skills so as to boost their job satisfaction and increase work efficiency and initiate work-life balance programs. Key words: Work locus of control, Workplace stress, Job satisfaction: personnel at the CCAA

Alula Gebru Atsbeha The Graduate School Korea Aerospace University 2022 국내석사

As we all know, Different efforts carried out by various experts to reduce incidents and accidents in aviation & other industries so far, though they were not adequate, continuous, and comprehensive. But now, there is an emerging concept called safety culture, which fosters safe practices and safe working conditions and addresses safety-related issues. So, establishing a culture of safety within an organization is the most effective and efficient approach to tackle unsafe behaviors and unsafe conditions, which are the leading causes of fatalities and property damage in aviation and other sectors. The purpose of this research was to assess the safety culture and associated factors in Addis Ababa bole international airport. A survey questionnaire was adapted from the Nordic Safety Climate Questionnaire (NOSACQ-50), which has two parts (the first containing socio-economic, Demographic, and Behavioral factors and the second containing 50 questions from the Nordic safety climate questionnaire). A total of 134 employees have participated in this study with a response rate of 100%. Out of the 134 respondents, 117 participated in the survey, and 17 participated in key informant interviews. Data were collected from 10 departments where an Institutional based Cross-Sectional Qualitative & Quantitative design study was employed using simple and stratified random sampling methods. Questionnaires, observations, and interviews were used as data collection tools. Secondary data was also collected from journals, research reports, books, ECAA and ICAO documents & company databases (the accident incident and occurrence reporting trend), and unpublished reports. Microsoft Excel and SPSS (Statistical Package for Social science) version 16.0 were used for data analysis. The airport mean safety culture score was 2.89≈2.9 which is a calculative level (2.70 –2.99), and 52.1 % of participants responded above the mean score. A Pearson product-moment correlation coefficient & simple linear regression was employed to investigate whether safety culture can be positively affected significantly based on monthly income, work experience, family size & age. In addition, Cross tabulation Eta squared statistics were used to examine the association between nominal variables (education level, Shift, Marital Status, Job Satisfaction, Safety Awareness, Physical Exercise, Home Proximity, Gender, & Position) & interval variable (Workers Safety Culture). Therefore According to the linear regression, an individual with higher monthly income, work experience, family size & age showed a significant positive relationship with higher safety culture. And according to the cross-tabulation eta squared statistics used, a significant association was observed between education level, marital status, safety awareness, & position with workers safety culture whereas, other variables like shift, job satisfaction, physical exercise, gender & location of the workplace from home showed an insignificant low-level association. Keywords; Safety culture, NOSACQ-50, Safety management system, work experience, family size, educational level, job satisfaction, safety awareness.

BABACAR LO The Graduate School Korea Aerospace University 2022 국내석사

With the rapid development of the air transport industry we assist of the creation of new airlines, airports and routes. It’s urgent to manage delays for reduce economic losses, and increased safety issues in air transportation systems. Due to increase of passenger demand, it’s important to identify the key element that hinder the efficient management of air traffic in order to protect air traffic controllers to overload and optimizing airspace operation. Capacity is the attitude of an airport to manage a number of operations in a given time interval within a fixed maximum delay. Due to a significant growth in air traffic activity, airspace capacity has become a limitation over the previous decade. Capacity estimation is a key technology in the implementation of effective designing and planning airspace also rational allocation of daily air traffic resources. Capacity estimation methods can be divided into 2 different groups: • Capacity estimation methods based on workload modelling • Capacity estimation methods based investigating impact of weather and geometrical constraints on airspace capacity. This thesis focuses on the simulation model to assess the capacity of the Terminal Maneuvering Area, using TAAM, taking into account restrictions as separation minima between aircraft, restrictions and approach procedure (ILS or GNSS). The model is used to evaluate the future performance of the airport in terms of capacity and the level of congestion that could be reached in the TMA.
