The present study investigated gender differences of dating violence among adolescents and related variables, and examined the difference in trait anger and anger expression between those who have inflicted dating violence and those who have not. Results indicated that female adolescents(41.9%) reported experience of inflicting dating violence more frequently than male adolescents(29.1%) did. The girls were more positive toward violence than the boys, while the boys were more expressing aggression at school than the girls were. Adolescents who had inflicted violence toward their dating partners had singificantly higher frait anger and anger-out than adolescents who had not. Logistic regression analysis indicated that father to mother violence, community violence, trait anger, and recipient of dating violence are predictors of dating violence for male, while father to mother violence, community violence, history of violence, and recipient of dating violence are predictors for female.

The Cretaceous Yucheon Group is volcano-sedimentary successions that are formed by volcanic activities of the Gyeongsang Volcanic Arc. Lack of the detailed field researches on the Yucheon Group results in poor understanding of the formation time and the tempo-spatial development of the volcanic arc. Also, this causes difficulties to reconstruct the depositional history from the Sindong and Hayang groups to the Yucheon Group. In this study, we conducted field research targeting to the interface between topmost part of the Hayang Group and the lowermost part of the Yucheon Group from Hyeonpoong to Bugok areas. We also identified depositional timing of the lowermost part of the Yucheon Group using SHRIMP U-Pb zircon age dating. This Yucheon Group is composed of tuff and lapilli tuff, conformably overlying the Jindong Formation. The results of SHRIMP U-Pb zircon age are 97 to 96 Ma, indicating cessation of deposition of the Hayang Group at 97 to 96 Ma by input of pyroclastic materials into the Jinju Subbasin during the explosive volcanic eruptions from the Gyeongsang Volcanic Arc. In comparison with field researches and results of LA-ICP-MS zircon U-Pb age dating (88-85 Ma) of the lowermost part of the Yucheon Group in Gyeongju areas, the volcanic activities that formed Yucheon Group and their influence ranges varied tempo-spatially. This is probably due to distance difference from the volcanic arc or establishment of the paleo-drainage system from the Gyeongsang Volcanic Arc to nearby lowlands.

This study set up research models and hypothesis in order to analyze those factors assuming that swift trust affects group cohesiveness, group cohesiveness affects organizational civil activities and organizational effectiveness (job satisfaction and organizational commitment) and at the same time plays as a medium for the swift trust, organizational civil activities and organizational effectiveness. Based upon these finding, variables in the ship unit are analyzed through surveys. This shows that the swift trust has statistically a meaningful and beneficial impact on group cohesiveness which has statistically a meaningful and beneficial impact on organizational civil activities and organization effectiveness. In terms of effects of crew members' the swift trust on organizational civil activities, organizational commitment, and job satisfaction, group cohesiveness has a partial medicated effect.. This paper has its significance in practically proving that the established swift trust of crew members increase group cohesiveness, the heightened group cohesiveness results in the changes of behaviors and attitudes of crew members in the seagoing vessel.

In order to understand the relationship between succession of phytoplankton community structure and inorganic nutrients and particulate organic matters, a one station in Kyungan stream in Korea during the dry season was chosen. Water samplings were carried out once a week from 18 August to 13 November 1993. The DIN concentration distributed always abundantly, however, phosphate and silicate gradually reduced during the period. Phytoplankton community had a peak chlorophyll a concentration of $90.6\;{\mu}g/l$ in late summer (21 August 1993) and a second peak of $29.7\;{\mu}g/l$ in autumn (2 October 1993). After then late autumn was characterined by relatively low chlorophyll a concentration of $15{\sim}16\;{\mu}g/l$. Seasonal fluctuation of chlorophyll a concentrations were correlated with measured POC and PON concentrations: phytoplankton blooming may be a major factor controlling POC and PON concentrations in this ecosystem. Phosphate plays an most important role as a limiting factor of phytoplankton growth. However, when Si/P ratio low, silicate may be a more critical limiting factor than phosphate. Shifts of P-limitation to Si- limitation the succession of dominant phytoplankton can in duce: diatom to cyanobacteria such as Anabaena, Microcystis and Oscillatoria.

The goal of this study is to examine consumers' cognition for the corporate social responsibility(CSR) and opinion to practical use of CSR on advertising (ex. corporate PR) in situation that CSR is treated with long-term and continuous activity in strategic marketing. The results of survey in this study are, first, the best effective method of CSR to introduce is TV or radio program placed first, internet came second, and followed by advertising. But the cognition process of CSR is internet palaced first in frequency. Thus it is very important to use of new media as a internet with regard to CSR. Second, respondents have thought positively about CSR and to practical use of CSR on advertising. But respondents answered that CSR is not enough though it's importance. Therefore marketers of companies is needed to transfer direction of CSR accord with consumers' liking and taste. Third, consumers have recognized that CSR in connection with characteristics core business of the companies. It is, image of company is not detached with CSR, more effective that CSR reflected characteristics of the company. Fourth, consumers have thought to active for CSR that the companies they like. Finally, these results are showed that is important brand management and corporate image management in strategic and macroscopic level include CSR.

The objective of this study is to develop the water quality and aquatic ecosystem model for Andong lake using SWAT-WET (Soil and Water Assessment Tool-Water Ecosystem Tool) and to evaluate the applicability of WET. To quantify the pollutants load flowing into Andong lake, a watershed model of SWAT was constructed for Andong Dam basin (1,584 km²). The calibration results for Dam inflow and water quality loads (SS, T-N, T-P) were analyzed that average R² was more than 0.76, 0.69, 0.84, and 0.60 respectively. The calibrated SWAT results of streamflow and nutrients concentration was used into WET input data. WET was calibrated and validated for water temperature, dissolved oxygen, and water quality concentration (T-N, T-P) of Andong lake. The WET calibrated results was analyzed that PBIAS was +19%, -13%, +4%, and +26.5% respectively and showed that it was simulated to a significant level compared with the observation data. The observed dry weight (gDW/m²) of zoobenthos was less than 0.5, but the average value of simulation was analyzed to be 0.8, which is because the WET model considers zoobenthos with a broader concept. Although accurate calibration is difficult due to the lack of observed data, SWAT-WET can analyze the effects of environmental change in the upstream watershed on the lake based on long-term simulation based on watershed model. Therefore, the results of this study can be used as basic data for managing the aquatic environment of Andong lake.

The purpose of this study is to investigate the relationship between perception, perception, and relationship quality through technical analysis of perception of southern food among college students of Namdo area. Through the analysis and empirical analysis, we tried to provide an understanding of local traditional foods and provide them as a basic data for local traditional food as a tourism resource. It directly or indirectly supports the results of previous studies. It directly or indirectly supports the results of previous studies. Therefore, the perception that can be expressed by knowing the characteristics of the local food is expressed by the continuous relationship and maintenance of the local food, so that the trust, the commitment, and the satisfaction expressed as the quality of the relationship can be expressed as the continuing relationship, maintenance and interest. If the meaning of local food and storytelling are given in order to induce growth and development of food tourism as a local food, it will be very helpful for building image of local traditional food. If local food is perceived as a favorable or unattractive attitude, it will be related to meaning and continuous interest and food and beverage behavior as local people such as active interest and pride in local food, It is believed that food will play a big role in the growth and development of tourism resources.

The layout includes various functions not only arrangement, connection, division of information but also affordance and information recognition as the important element that determine the whole structure of information. Recently, the layout of web interface design was gradually changing from the concept of the original Z-layout to F-layout, whereas, it is being changed again into the split layout as the transform of Z-layout. However, there can be lack of grounds as to the reason of the change of layout. Therefore, it needs to study on how the functional difference between the F-layout and Z-layout affects user experience. In this study, we conduct the study on the effect of each layout type on the user experience focusing on the product description of web-page by user test. The user test have shown that the user has better feeling on the split layout based on the Z-layout than F-layout. The Z-layout also has more advantages on the formation of the favorable attitude of user in efficiency, accessibility and concentration. This result is consistent with the trend of web-design to change into the split layout based on the Z-layout and we provided the objective reasons for the effective web-design layout by user test.
