  • Individuals majoring in Library and Information Science (LIS) typically find employment in the library sector, such as working as librarians, university librarians, and in public libraries. Recent advancements in information technology and shifts in work outlooks have broadened the professional opportunities for students majoring in LIS in several sectors. Research on career exploration varies based on the university major or occupation. This paper suggests a methodology for conducting surveys and analyzing data efficiently to support ongoing career exploration for students majoring in LIS. It also examines the findings of a career exploration survey conducted among LIS majors. The survey findings indicate that individuals majoring in LIS are adapting their salary expectations and priorities in alignment with societal shifts, showing a preference for diverse career opportunities outside traditional librarian roles. Effective support and ongoing research are essential for the career development of LIS majors in this environment.

  • One of the most general methods that can evaluate the rippability is the seismic exploration. However, most field engineers have hardly used the seismic exploration. Instead of using the seismic exploration, they have usually used rock hammer and naked eyes to confirm the degree of rippability for soil, ripping rock and blasting rock. Therefore, to excavate the ground rationally, it is required to establish a quantitative criterion that can be used for distinguishing rippability. In this study, we find out the characteristics of rock strength through laboratory and field tests. The weathering condition of rock exposed to air due to excavation of soil layer and the variation of rock strength caused by weathering were investigated. A relationship between rock strength values that are obtained from uniaxial compression test, slaking durability test, point load test, schmidt hammer test and absorption ratio test is analyzed. The relationship is expressed in a form of equation by which we can evaluate the rock strengths obtained from simple laboratory and field tests. To evaluate rippability in a reasonable manner, a quantitative approach is proposed and a check list of rippability is developed based on the proposed methodology. It is recommended to modify the proposed method for evaluation of rippability in the field.

  • Purpose - This paper investigates the relations among exploratory and exploitative supply chain management practices, competitive advantage, and firm performance. Design/methodology/approach - This study takes a hypothesis-generating study to capture the tradeoffs between exploration and exploitation and develops some hypotheses which involve the relations among SCM practices, competitive advantage, and short-term and long-term performance. Findings - Exploitative SCM practices have more positive effects on short-term performance rather than long-term performance, whereas exploratory SCM activities affect long-term performance. Further competitive strategy, environmental dynamism, and organizational slack moderates the relationship between SCM and performance. Exploitative SCM is more desirable when a firm uses low cost strategy, lacks slack resources, and faces stable environment, while exploratory SCM is more effective when a firm employs differentiation strategy, has slack resources, and confront dynamic environment. Research implications or Originality - In order to understand the performance effects of a variety of SCM practices, we should distinguish between exploitative and exploratory SCM activities. Further the relationship between SCM and performance may differ depending upon some contingent variables such as external environment, competitive strategy and organizational slack.

  • This paper presents a high-level design methodology applied on an SoC using SystemC. The topic will emphasize on high-level design approach for intensive architecture exploration and verifying cycle accurate SystemC models comparative to real Verilog RTL models. Unlike many high-level designs, we started the poject with working Verilog RTL models in hands, which we later compared our SystemC models to real Verilog RTL models. Moreover, we were able to use the on-chip test board performance simulation data to verify our SystemC-based platform. This paper illustrates that in high-level design, we could have the same accuracy as RTL models but achieve over one hundred times faster simulation speed than that of RTL's. The main topic of the paper will be on architecture exploration in search of performance degradation in source.

  • Purpose - Without question, globalization has presented different opportunities to entrepreneurs seeking to expand their companies in foreign markets. The aim of this study is to examine the relationship between entrepreneurial orientation, entrepreneurial activity, information internalization, and product differentiation in export oriented firms. As such, entrepreneurial activities are divided into exploitative and exploratory opportunities. These opportunities are crucial in improving firms' performance. Design/methodology - A structural questionnaire was developed using 21 factors/indicators from previous researches. The subjects of this study were recruited using convenience sampling in export SMEs in the Seoul Metropolitan Area. Data were collected through visits or e-mails from the export managers, executives, and CEOs of export SMEs in advance. 321 questionnaires were collected over a period of one month. 316 questionnaires were used in the final analysis. Findings - First, International Entrepreneurial-orientation (IE) has a positive effect on the exploration and exploitation of business opportunities. Second, the exploration and exploitation of business opportunities have a positive impact on information internalization. Third, information internalization has a significant effect on product differentiation and plays a mediating role in seeking opportunities, utilizing opportunities, and differentiating products. Originality/value - This study contributes to the development of academic discussions by explaining existing research gaps. First, there is currently a lack of research focusing precisely on the product differentiation capability of SMEs in manufacturing field in terms of IE. To bridge these gaps, we examined the entrepreneurial factors impact on product differentiation and tries to expand the discussion about the internationalization of SMEs, which were mainly focused on IT companies, and manufacturing companies. Second, there is no intuitive explanation regarding international entrepreneurial activity in terms of exploration and exploitation within existing. In this study, international entrepreneurship activities were classified in terms of exploration and exploitation.

  • Geophysical methodology using GPR(Ground Penetrating Radar) were applied both to the limestone producing area(Sambo Mine Company & Haksanri Area) and to Landfill area(Mureung Landfill Site). The investigation results resultant from both the limestone producing area(Sambo Mine Company & Haksanri Area) showed that there are a few events reflected from boundaries between caves and basement rocks. Those from landfill area showed that more complicated and small size events are found. These events could be from different electric characteristics of various kinds of composition materials in the landfill site.

  • City gas is becoming an essential resource in households due to its convenience and low price in comparison to other energy sources. However, in order to prepare for the gas market to be saturated, many city gas companies must pursue customer satisfaction management and develop happy call systems for a promising solution. In the development of the happy call systems, the difficult problem is that we cannot contact all customers because of limited resources and calling efficiency in the call center, We should find best customers according to their value. This paper suggests a methodology for the selection of happy call customers when city 9as companies consider two strategies. First, they should launch a new business area. Second, they must attempt to prevent current customers from moving from city gas to other fuels. We will discover important attributes and derive rules of weighting for the attributes through an exploration study that affect customer satisfaction and preference. Through a simulation model, we will show how many customers will be selected by our methodology.

  • The MPEG user description (MPEG-UD) which is a standard under exploration to ensure interoperability among customized recommendation services has been contributed since MPEG $104^{th}$ meeting at 2013. Twenty-two use cases that were divided into different applications have been proposed in the MEPG meetings. Most of use cases were referred to specific and restricted regarding to applications, it appears to miss an overall and explicit infra-structure. In this paper we describe a reference model, namely methodology to overcome aforementioned problems. Thereafter, we have applied reference model to context-based recommendation system to demonstrate the methodology and MPEG-UD schemas. In addition, we propose a development process of recommendation system in compliance with MPEG-UD.

  • Fatigue life prediction of a multi-row countersunk riveted lap joint was performed numerically. The stress and strain conditions in a highly stressed substructure of the joint were analysed using a global/local finite element (FE) model coupling approach. After validation of the FE models using experimental strain measurements, the stress/strain condition in the local three-dimensional (3D) FE model was simulated under a fatigue loading condition. This local model involved multiple load cases with nonlinearity in material properties, geometric deformation, and contact boundary conditions. The resulting stresses and strains were used in the Smith-Watson-Topper (SWT) strain life equation to assess the fatigue "initiation life", defined as the life to a 0.5 mm deep crack. Effects of the rivet-hole clearance and rivet head deformation on the predicted fatigue life were identified, and good agreement in the fatigue life was obtained between the experimental and the numerical results. Further crack growth from a 0.5 mm crack to the first linkup of two adjacent cracks was evaluated using the NRC in-house tool, CanGROW. Good correlation in the fatigue life was also obtained between the experimental result and the crack growth analysis. The study shows that the selected methodology is promising for assessing the fatigue life for the lap joint, which is expected to improve research efficiency by reducing test quantity and cost.
