직무를 어떻게 설계 하느냐에 따라 근로자의 심리적 상태가 달라지며, 개인과 조직의 성과에도 영향을 미친다. 본 연구는 업무의 효율성 증대를 위한 방안 모색에서 출발하였다. 따라서 본 연구의 목적은 국내 금융업에서 주요 직무특성과 성과요인 간의 관계를 규명하는 것이다. 이를 통해 금융 조직의 효율성 증대를 위한 가이드라인을 제시하고자 한다. 연구의 목적을 달성하기 위한 개념적 모델은 Hackman & Oldham의 직무특성모델과 기존 문헌연구를 통해 구축하였다. 그리고 개념적 모델과 가설을 검증하기 위하여 국내 금융업종사자를 대상으로 설문조사를 실시하였으며, 자료는 구조방정식모델링 기반으로 분석하였다. 분석결과는 첫째, 직무에서의 다양성과 자율성은 기업혁신, 자긍심 그리고 직무만족에 긍정적인 영향을 미친다. 둘째, 기업혁신과 직무만족은 직무몰입에 긍정적인 영향을 미치는 것으로 조사되었다. 저금리 기조가 장기화되는 현 상황에서 금융기관의 직무특성과 조직성과 간의 연구는 조직의 효율성 증대에 많은 기여를 할 것이다.

Under the current dynamic business environment, the corporate knowledge resources are becoming more complicated and diverse. In order to manage these resources effectively, it is necessary to develop an integrative metaschema which accommodates various characteristics of the resources. From this perspective, this paper proposes an integrative metaschema which can manage three types of knowledge resources: schematic model, hypermedia information, and document file. This metaschema can help store and reuse knowledge in a systematic and consistent way. Furthermore, it can support useful and flexible search logics. To demonstrate the usefulness of the metaschema, a prototype system and a real-life bank case are illustrated.

무선링크에서 TCP의 성능을 향상시키기 위한 연구들이 많이 수행되었으며, 다양한 기법들이 제안되고 있다. 하지만, 대부분의 연구들이 TCP 송신측이 무선링크에서의 패킷 손실을 혼잡으로 오해하는 문제를 해결하는데 초점을 맞추고 있다. 또한 이러한 연구들은 대부분 시뮬레이션을 통해 측정되고 검증된 결과들이기 때문에 실제 환경을 반영하는 데는 완전하지 않다. 본 논문에서는 SKT의 CDMA2000­1x 상용 망에서 삼성전자의 SPH­A500 단말기를 이용하여 TCP와 UDP의 성능을 측정하였다. 본 연구에서는 CDMA2000­1x의 정확한 특성을 측정하고 분석하여. 무선링크에서의 delay spike에 의한 불필요한 timeout을 방지하고, 병목 링크에서의 큐 길이를 안정되게 유지하는 방법을 고안하고자 한다. 이를 위해 본 논문에서는 측정 과정에서 분석된 CDMA2000­1x의 특성을 정리한다.

유선망에 최적화되도록 진화해온 TCP 는 GPRS, CDMA2000-1X 등의 무선망에서는 제 성능을 발휘하지 못한다는 것은 이미 널리 알려진 사실이며, 이를 극복하기 위한 방법들이 상당수 제안되었다. 하지만 제안된 연구들의 대부분은 이미 3G 서비스의 링크 계층에서 상당부분 해결된 무선 링크에서의 손실을 혼잡으로 오해하는 TCP 의 문제점을 해결하기 위한 것이다. 본 논문에서는 무선 링크에서의 손실보다는 무선 링크로 인해 야기되는 길고 변화가 심한 전송시간으로 인해 발생하는 TCP 의 문제점을 제시하고, 이를 해결하기 위한 방법을 제안한다. 특히, 본 연구에서는 시뮬레이션이 아닌 실제 CDMA2000-1X 망에서 단말기를 통해 측정된 자료를 기반으로 문제점을 도출하여 기존에 제안된 연구들과 차별화 한다.

This study investigates the impact of corporate governance (defined as companies' ownership structure and board of directors' characteristics) on cash holdings in the context of Oman. This study leverages a quantitative panel pooled regression on a dataset of Omani non-financial firms from 2009-2015. The findings of this study are generally in line with the predictions of Agency Theory and Mentoring and Busyness Hypotheses. The analysis demonstrates that a large stockholder size has a significant positive relationship with cash holding. Meanwhile, a positive (but insignificant) relationship was also found between institutional ownership and cash holding. Furthermore, state ownership was found to exhibit a significant negative relationship with cash holding. In terms of the board of directors' traits, this study's findings suggest that board sizes have a positive (but insignificant) relationship with cash holding. Furthermore, busy and independent boards were found to have a significant positive relationship with cash holding. The above findings suggest that boards with such traits are less effective in providing oversight on managers' actions, which would then increase Omani non-financial firms' cash holdings.

Hydrogen is used as a chemical feedstock in several important industrial processes, including oil refineries and petro-chemical production. But, nowadays hydrogen is focused as energy carrier on the rising of problems such as exhaustion of fossil fuel and environmental pollution. Thermochemical hydrogen production by nuclear energy has potential to efficiently produce large quantities of hydrogen without producing greenhouse gases, and research of nuclear hydrogen, therefore, has been worked with goal to demonstrate commercial production in 2020. The oil refineries and petro-chemical plant are very large, centralized producers and users of industrial hydrogen, and high-potential early market for hydrogen produced by nuclear energy. Therefore, it is essential to investigate and analyze for state of domestic hydrogen market focused on industrial users. Hydrogen market of petro-chemical industry as demand site was investigated and worked for demand forecast of hydrogen in 2020. Also we suggested possible supply plans of nuclear hydrogen considered regional characteristics and then it can be provided basis for determination of optimal capacity of nuclear hydrogen plant in 2020.

Incheon International Airport is total number of passengers using that increased by 8.3 percent year-on-year, with the highest level of user ratings since the opening of the previous year. Thus, After analyzing the positive image of Incheon International Airport and analyzing future corporate image development, the company conducted a study on improving the image of Incheon International Airport. Based on the SERVQUAL method, the study classified the five types of SERVQUAL. The difference in the distinctions of the media coverage varied, and the differences in the credibility of the media show that the differences between the press and the credibility of the media are not reflected in the characteristics of the media. These findings will provide data for the managerial control of corporate images based on positive or negative reporting on the Incheon International Airport, and based on the analysis of the findings, it is believed that it will benefit from being the most high-profile airport.

A polymeric host for triplet emitters composed of N-alkylcarbazole and tetramethylbenzene units was successfully synthesized. Efficient energy transfer was observed between this polymeric host and green phosphorescent dyes. The device fabricated using 5 wt% green 1 in the polymeric host as the emitting layer showed the best performance. Thin films of this host-guest system, exhibiting clear stripe patterns could be prepared through the LITI process. The patterned films were then used to fabricate electrophosphorescent devices, which show performance characteristics similar to those of spin-coated devices. The new host material is a good candidate to be used in polymer-based full-color electrophosphorescent light-emitting displays.

This study seeks to investigate Key Audit Matters (KAMs) reporting of Thai listed companies in Thailand, and examines the influence of KAMs reporting on corporate financial performance. Data were collected from 180 companies listed in Thailand during 2016 to 2018, which accounted to 540 annual reports. KAMs reporting was quantified by content analysis from the audit reports, while financial performance and corporate characteristics were collected from the corporate annual reports. Descriptive analysis and multiple regressions were performed to analyze the data. The study results reveal that there was an increasing of KAMs reporting in audit report of listed companies in Thailand in terms of both number of issues and number of words across the observed period. The regression analysis indicates that was a significant and negative influence of words counted as KAMs reporting on financial performance, while there was no influence of KAMs reporting issue on the performance. Moreover, there was a negative relationship between corporate complexity and financial performance, while audit type had a positive correlation with financial performance. This study shows significant contribution on the implication of KAMs in an emerging economy and the role of KAMs as a communication device between auditor and stakeholders.

This study aims to consider the role of women serving in the executive committee of the company and determine how it related to corporate social and environmental responsibilities (CSR and ESR). The data was collected from the 344 companies listed on the Stock Exchange of Thailand (SET) between 2013 and 2014. Especially, the CSR and ESR data was collected from the annual report and used to measure activities related to environmental and social responsibilities of companies listed on the SET. This study employed panel analysis regression to analyze the relationship between dependent and independent variables. The results indicated that the role of women who served in the executive committees of companies listed on SET had a positive impact on the social and environmental responsibilities of companies listed on the SET. The Granger causality test showed that the proportion of women holding positions on the board of directors had a statistically significant relationship with CSR and ESR, which is a unidirectional relationship. Moreover, the size of the company and the return to total assets also have a positive significant relationship with the CSR and ESR.
