With the full-fledged start of the 4th Industrial Revolution, the quality of administrative services through intelligent information technology and demand increased rapidly. Accordingly, the government is in full swing to establish a "digital platform government" through digital innovation in existing e-government operations such as organizational operations and administrative services. As local governments also promoted the establishment of a digital-based Agile government as a key strategy, this study investigated and analyzed the operation of informatization experts in metropolitan and basic local governments to support digital transformation policies and projects through intelligent informatization. Through this, the necessity and implications of expanding the size of human resources for successful digital transformation were derived, and two measures were proposed to enhance capabilities and expertise in the process of securing new manpower.

In light of the COVID-19 incident, organizations have recognized the importance of systematically managing knowledge resources to enhance work efficiency and performance within the organization. We have adopted the perspective of knowledge hoarding, which entails the ownership of individual knowledge, and aim to elucidate the underlying mechanisms that contribute to knowledge hoarding by considering the organizational environment, personal characteristics, and task characteristics. To test our hypothesis, we conducted a survey among employees working in companies that have implemented knowledge management policies or systems. We obtained a total of 381 samples, which were analyzed using AMOS 22.0 and Process 3.1 macros. Our findings reveal that distributive injustice leads to conflicts relationships and subsequently increases individual knowledge hoarding. Furthermore, we found that sensitivity to incentive interacts with distributive injustice, further exacerbating knowledge hoarding. Conversely, task interdependence mitigates knowledge hoarding by interacting with distributive injustice and relation conflict. These results contribute to the development of effective organizational knowledge management strategies aimed at curbing knowledge hoarding within the organization.

Socially, organizations are required to maintain strict management of their information resources and invest in the adoption of information security (IS) technologies and policies. However, the ongoing threat of information exposure by employees persists within the organization. This study aims to identify the role stress that employees may experience due to strict IS policies and propose methods for reducing its negative impact. Specifically, our study suggests a mechanism for mitigating role stress by incorporating factors related to IS policy goal setting and work regulatory focus. We conducted a survey among workers in the financial industry, where IS policies are rigorously enforced, and tested our research hypotheses using a sample of 309 participants. The results indicate that increasing the difficulty and specificity of IS policy goals reduces role stress (conflict and ambiguity) and positively influences employees' intention to comply with IS policies. Furthermore, individual work promotion focus moderated the relationship between role stress and IS compliance intention. These findings have important implications for organizations seeking to strengthen their IS compliance among employees and inform the development of effective IS strategies.

Increasing energy efficiency in factories is an activity aimed at optimizing resource allocation in manufacturing processes to establish production plans. However, this strategy may not apply effectively when night shifts are unavoidable. Additionally, continuous fluctuations in production requirements pose challenges for its implementation in the factory. Recently, with the rapid proliferation of electric vehicles (EVs), technology utilizing electric vehicle batteries as energy storage systems has gained attention. Technology using these batteries can be an alternative for factory energy management. In this paper, a factory energy management method using EV batteries is proposed. The proposed method is analyzed using PSCAD/EMTDC software, considering the state of charge of EV batteries and Time-of-Use (TOU) rates. The proposed method was compared with production scheduling established considering predicted power usage and TOU rates. As a result, production scheduling saved 4,152 KRW per day, while the proposed method saved 7,286 KRW in electricity costs. Through this paper, the possibility of utilizing EV batteries for factory energy management has been demonstrated.

본 연구의 목적은 2008년 후반에 발생한 국제금융위기에 대응하여 조직 개편을 선택한 기업과 그 기업 내의 근로자들 실태 파악을 하는데 있다. 특히 기업구조조정 명목으로 단행된 해고를 모면한 근로자들 (생존자)의 상태를 그들이 지각하는 각 개인의 관리자에 대한 만족도와 그들의 직무관련태도인 직무만족, 조직적 몰입 그리고 이직 의도 간의 관계 관점에서 살피고자 한다. 관리자에 대한 만족도는 근로자들의 직무 관련 태도 변수와 관련되어 사회적 선행변수로 선택되었으며 직무관련태도는 결과변수로 선택하였다. 본 연구를 통해 생존자들의 조직 내 직무관련태도에 관한 이해를 높이는데 필요한 정보를 표출해내어 그들의 실태를 파악하는데 하나의 목적을 두었으며 그들의 관리자와의 사회적 관계가 그들에게 미치는 영향을 파악하는 것이 또 하나의 목적이라 하겠다. 이상과 같은 관계 파악을 통해 얻은 정보로 관련기업이 단기적으로 성공적인 자립을 하여 장기적으로 경쟁력 있는 조직으로 성장할 수 있는 인적자원전략을 제공하는데 2차적인 목적을 두고 있다. 본 연구는 이상과 같은 목적을 달성하고자 그 유의성이 증명된 현존하는 설문을 활용한 조사기법을 채택하여 실증연구를 하였다. 수집한 자료는 SPSS 17.0과 LISREL 8.5을 사용하여 연구모형과 연구의 가설들을 검증하였다. 연구목적을 달성하고자 채택된 가설들은 기존의 문헌연구를 토대로 세워졌다. 연구대상은 태국 북부지역의 대표도시인 치앙마이 내 관광호텔 종사자들로서 외부적으로는 2008년 국제금융위기와 그에 따른 경제침체, 내부적으로는 극심한 정치적 사회적 불안에 의한 관광객의 급감소와 조직의 자구책으로 행해진 조직재구조 차원에서의 해고를 이겨낸 근로자들, 즉 생존자들이었다. 가설검증을 통해 입증된 연구결과에 의하면 1) 근로자들의 관리자에 대한 만족은 그들의 직무만족, 정서적 조직몰입과 지속적 조직몰입에 영향을 미치는 것으로 검증됐다. 2) 근로자들의 관리자에 대한 만족은 그들의 이직의도에는 영향을 미치지 못하는 것으로 검증됐다. 3) 근로자들의 직무만족은 그들의 이직의도에 영향을 미치는 것으로 검증되었다. 4) 근로자들의 조직적 몰입과 이직의도 간의 관계에 있어서는 오직 경제적 성격의 지속적 조직몰입만 영향을 미치는 것으로 검증되었다. 이러한 연구 결과는 기존의 타 연구 결과와 기본적인 맥락은 같게 나왔으나 근로자들의 정서적인 면의 부재는 2008년 후반 당시의 독특한 태국의 사회적, 경제적 그리고 문화적 실태를 보여주는 것이 아닌 가 사료된다. 특히 근로자들이 그들의 직장과의 관계와 관련된 의사결정을 가치가 아닌 경제적인 요소에 의존한다는 결과 그리고 상관인 관리자가 이러한 태도에 전혀 영향력을 미치지 못한다는 결과는 전통적으로 감성적이며 집단주의적인 동양적 문화가 지배하리라고 예상했던 태국에서는 이례적인 결과였다. 그러나 관리자들이 그들의 직무만족 그리고 조직적 몰입에 영향을 주며 직무만족이 이직 의도에 영향을 미친다는 결과와 지속적 조직몰입이 이직의도에 영향을 미친다는 결과는 장기적으로 적극적인 관리자 교육을 통해 근로자들을 조직에 정서적으로도 올바르게 안착시키고 긍정적인 구성원으로 존재하면서 조직에 기여할 수 있는 그들의 역할을 기대할 수 있다고 볼 수도 있다. 이 점은 매우 중요한데 그 이유는 해고를 이겨낸 근로자들은 그 조직이 미래를 짊어지는 마지막 기대변수이기 때문이다.

Recently, an understanding of new sources of liquid hydrocarbons such as bioethanol is economically very important. Bioethanol is actually ethyl alcohol or also referred to as ethanol, identical to drinking alcohol by its composition. There are mainly two ways of producing ethanol, namely by synthesis of hydrocarbons and from biomass. Only the second approach deserves the terminology 'bioethanol'. The present dissertation is also designed with purpose of developing the energy-saving process for the separation of bioethanol. The world population is expected to grow past 8 billion by 2030 which are almost 60% in Asia Pacific. History has shown that energy use rises much faster than population expands. World wide demand for energy will increase significantly during the next 15 years driven by population growth and the transition of emerging markets into the global economy. In developing nations, a smaller increment in GDP per capita yields a higher increment in energy consumption compared to developed countries. In this study, we analised total 2,454 dissertations for the bioethanol during the 2001~2012 periods by the programs of 'web of science' and 'recently developped program by Korea Institute of Science Technology Information'.

Zirconium is one of the most important material used as cladding of fuel rods in nuclear reactors because of its high dimensional stability, good corrosion resistance and especially low neutron-absorbing cross section. However, Hf free nuclear grade Zr sponge is commercially produced by only three countries including USA, France and Russia. So, Zr has been thoroughly managed as a national strategic material in Korea. Most of the zirconium is used for Korean nuclear industry as nuclear fuel cladding materials manufactured from Hf free Zr alloy raw material. Also, there are some other applications such as alloying element and detonator. In this review, zirconium production and recycling technologies have been reviewed and current industrial status was also analyzed. And recent achievements in innovative reduction technologies such as electrolytic reduction process and molten oxide electrolysis were also introduced.

Intense competition for resources has forced many countries pay attention to their eyes to the ocean. Therefore, the disputes and the conflict over the delimitation of the EEZ and continental shelf will be sharpened. Since 1982 Law of the Sea Convention, Korea has opened the talks with Japan and China to discuss the boundary issues as the adjacent water zone is less than 400 miles between Korea and Japan and Korea and China. This study is to review the important rules and techniques for the delimitation of the maritime boundary which have defined in the Law of the Sea Convention and IHO-51 technical guide and to figure out how to build the maritime delimitation GIS DB to negotiate effectively with the neighboring countries. Definition of the base point and baseline will be the utmost important concept to delimit the ocean boundary. The policy makers and the specialists who prepare for the international negotiation meeting between the countries have to be ready to draw the maritime boundary for our best interest under the Law of the Sea Convention. The negotiation strategies and the principles can be made with the concrete and reliable database relevant to maritime boundary issues. So effective and fast strategic decision for negotiation can only be made based on maritime boundary delimitation GIS DB.
