Since Lau and Murnighan first introduced the concept of faultlines in 1998, there are many extended studies related to faultlines theory. It is obvious that faultlines theory adds valuable explanations in addition to what numerous previous demographic studies have explored. However, previous research has not been able to fully integrate the characteristics embedded in the workplace environments, and the influence of faultlines in IT industries has yet to be explored. So it is not reasonable and convincing to extend the findings from previous faultlines research to other industries in the global world. In this study, IT related influence is given considerable weight into traditional faultlines theory and the impact of IT-based faultlines is revealed. Our study indicates that IT-based faultlines have negative impact on task conflict, process conflict and relationship conflict, and also have negative impact on individual outcomes such as individual performance and satisfaction. The influence of IT-based faultlines on people s intend to remain in the current organization is found to be insignificant. Our empirical study reconfirmed that faultlines are important indicator in group works and also that faultlines are intimately related to various conflicts and individual outcomes. We hope our research findings would be beneficial to the organizations concerned with effective and efficient group work.

Scour means the erosion of bed material by flow change when a bridge is constructed in a stream. Scour is one of the critical factors of a bridge failure. There are several methods for the monitoring of scour near bridge foundations; Sounding rods, Magnetic sliding collar System, Sonar system, underwater camera system and so on. In general, Sonar system is preferred due to its convenience and good accuracy. In this study, the new scour monitoring system was developed using profiling sonar sensor. The new system can measure a line profile of a seabed and has small size due to the effectively designed data logger. The performance of the new scour monitoring system was evaluated at a bridge pier in tidal environment. The measured local scour depths were discussed with the result of the empirical formulas; CSU, Froehlich, Laursen and Neill.

The purpose of this study is that problems caused by labor environment of cuisiniers in hotels need to be considered and studies regarding a part-time cuisinier in a special-grade hotel need to be conducted. This study analyzes the influence of labor conditions and organizational commitment of a part-time hotel cuisinier on duty satisfaction. It consists of two parts: a research based on the review of the literature and empirical study methods. The method of human resource management in hotels such as treatment of a part-time cuisinier in a special-grade hotel and the way of management as a result of an empirical study are proposed. First, as a result of conducting research on duty satisfaction to part-time cuisinier, most of them are highly satisfied with their duty regardless of their age and academic backgrounds. Second, men hold a majority; woman staffs tent to have a had time working overtime considering the situation that hotels run for 24 hours. That is the main reason why less woman staffs work in hotels than man staffs do. Part-time staffs would like to work consistently after they get upgraded to a regular worker. Forth, it is considered to break down into detailed sectors and speciality is highly demanded.

Purpose: The purpose of this empirical research was to describe the contents what had happened to nurses experiencing taeoom. Methods: This study explored the phenomenological ways to understand lived experiences in nurses' 'Taeoom' and investigated the 'Taeoom' through the deductive content analysis. For the this study, the data was collected through individual interviews with 11 nurses who worked over 12months in 1 hospital, lived in 5 areas, working 7 nursing unit of 10 hospitals. The interviews conducted by semi structured questions about participants' lived experiences in 'Taeoom'. Results: Inductive contents analysis identified 5 categories and 15 subcategories. Main themes in this study included a failed membership, difficult of practical field adaptation, feared with nursing unit life, self-centered peer relationships and rite of passage. Conclusion: This study results have been illuminated with edged sword which has a dark side and a light side to experienced in 'Taeoom'. Newly employed nurses have suffering from 'Taeoom' as well as retained nurse. Therefore, policy and practice programs for a diminution of suffering and management for nurses 'Taeoom' should be developed and implemented.

We are developing empirical space weather (geomagnetic storms, solar proton events, and solar flares) forecast models based on solar information. These models have been set up with the concept of probabilistic forecast using historical events. Major findings can be summarized as follows. First, we present a concept of storm probability map depending on CME parameters (speed and location). Second, we suggested a new geoeffective CME parameter, earthward direction parameter, directly observable from coronagraph observations, and demonstrated its importance in terms of the forecast of geomagnetic storms. Third, the importance of solar magnetic field orientation for storm occurrence was examined. Fourth, the relationship among coronal hole-CIR-storm relationship has been investigated, Fifth, the CIR forecast based on coronal hole information is possible but the storm forecast is challenging. Sixth, a new solar proton event (flux, strength, and rise time) forecast method depending on flare parameters (flare strength, duration, and longitude) as well as CME parameter (speed, angular width, and longitude) has been suggested. Seventh, we are examining the rates and probability of solar flares depending on sunspot McIntosh classification and its area change (as a proxy of flux change). Our results show that flux emergence greatly enhances the flare probability, about two times for flare productive sunspot regions.

The three-dimensional orientation distribution function of a conical shaped tungsten liner prepared by the thermo-mechanical forming process was analyzed by 1.525$\AA$ neutrons to carry out the Rietveld refinement. The pole figure data of three reflections, (110)(220) and (211) were measured. The orientation distribution functions for the normal and radial directions were calculated by the WIMV method. The inverse pole figures of the normal and radial directions were obtained from their orientation distribution functions. The Rietveld refinement was performed with the RIETAN program that was slightly modified for the description of preferred orientation effect. We could successfully do the Rietveld refinement of the strongly textured tungsten liner by applying the pole density of each reflection obtained from the inverse pole figure to the calculated diffraction pattern. The correction method of preferred orientation effect based on the inverse pole figures showed a good improvement over the semi-empirical texture correction based on the direct usage of simple empirical functions.

The purpose of this research was to find out the most explainable variables influencing fashion leadership. This research was carried out by both the theoretical and empirical study. For the theoretical study, the research of fashion leadership was based on the fashion opinion leadership and innovativeness. The study included the analysis of variables influencing fashion leadership, such as clothing importance, clothing conformity, clothing anticonformity, perceived risk of clothing, use of fashion information source and demographic variables. For the empirical study, fashion leadership was measured by fashion opinion leadership and innovativeness. The variables influencing on the fashion leadership were measured by self-image, social participation, clothing behaviors(clothing importance, normative conformity, identificational conformity, clothing anticonformity, clothing independance), demographic variables(major fields of students, year of education, family income). Data were obtained from 335 female college and university students in Chung-Buk area by self-administered questionaire. The data collected through the questionaire were analyzed by the stastical thechique-stepwise regression. The results of the study were as follow: 44.6 percent of the total variance of fashion leadership was explained by the five variables: Clothing importance, use of marketer-dominated fashion information source, identificational conformity, traditional-modern self image and clothing anticonformity. Family income and the major fields of students are significantly related to the fashion leadership.

This research examines the alternative ways of estimating the coefficient of non-diversifiable risk, namely beta coefficient, in Capital Asset Pricing Model (CAPM) introduced by Sharpe (1964) that is an essential element of assessing the value of diverse assets. The non-parametric methods used in this research are the robust Least Trimmed Square (LTS) and Maximum likelihood type of M-estimator (MM-estimator). The Jackknife, the resampling technique, is also employed to validate the results. According to finance literature and common practices, these coecients have often been estimated using Ordinary Least Square (LS) regression method and monthly return data set. The empirical results of this research pointed out that the robust Least Trimmed Square (LTS) and Maximum likelihood type of M-estimator (MM-estimator) performed much better than Ordinary Least Square (LS) in terms of eciency for large-cap stocks trading actively in the United States markets. Interestingly, the empirical results also showed that daily return data would give more accurate estimation than monthly return data in both Ordinary Least Square (LS) and robust Least Trimmed Square (LTS) and Maximum likelihood type of M-estimator (MM-estimator) regressions.
