This paper investigates whether the announcement effect of seasoned equity offering is affected by management performance. We used Korean stock market data from 2000 to 2007 to analyze the possible relation between net income and seasoned equity offerings announcement effect. The sample of 308 firms are selected for the study from the original population of 750 seasoned equity offering announcements. and We analysis this article through event studty of Brown and J.Warner. We divide the data into two groups. - the previous offerings year's positive net income group and negative income group. Both positive and negative net income samples affect stock price positively. However, the CAR for the negative net income offerings becomes zero around 25days after the announcement date. To analyze the impact of accounting income on the seasoned equity offering announcement effects fully, we introduce a cross-sectional regression analysis by setting the cumulative abnormal returns as a dependant variable and net income as an explanatory variable. The beta coefficient of the net income shows a statistical significance. These results can be considered as an evidence to support our hypothesis.

This study investigated the effect of parental attachment on interpersonal competence and psychological well-being of college students. 625 college students completed self-administered questionnaires. Reliability test, ANOVA, Duncan ex-post analysis, and hierarchical regression analysis on data were used. Study results showed that parental attachement and interpersonal competence had significant effects on college students' psychological well-being. Results also depicted gender differences in the relationship of study variables; students' interpersonal competence demonstrated partial mediation effect in the relation of attachment with the same-sex parent and psychological well-being, while complete mediation effect in that of attachment with the opposite-sex parent and psychological well-being, These findings suggest that gender-conscious university policies to promote interpersonal competence among students are greatly needed to ensure psychological well-being of the student population.

The service quality survey for the customers of Gwangyang container port has been done since 2005. It has been difficult to compare annual levels or rival ports because the calculation of weights among service dimensions that is the most important procedure of the assessment systems did not be founded. In particular, the calculation results by the Analytical Hierarchy Process that specializes in estimating the weights were very unstable and not comparable because they were fluctuated annually more than 90% for the specific item. The objective of this study is to support the establishment for new assessment system of service quality with cost- and time-effective tools at Gwangyang port. The confirmatory factor analysis methodology applied to 2007-2009 survey data from the customers of Gwangyang port can estimate ex-post weights to measure annually the stable service quality. The proposed methodology allows us to build the assessment system of more scientific and accurate service quality while reducing the survey items. By this study, a port company can measure accurately the quality of service and improve its competitiveness through being compared to previous periods and leading companies.

This study shows the results of constructing panel data using Farm Household survey and presents some examples of empirical application. This study shows that ex post constructed panel data using repeated cross-sectional survey can be used in various dynamic analyses. This paper also shows that the well known difficult problem of longitudinal weights can be easily solved by using the existing cross-sectional weights in original cross-section data. Based on these results, we propose that the National Statistical Office not only try to construct panel data, but also construct panel data by using existing repeated cross-section data. The benefits of this approach seems to be very big in establishment survey.

Although ionizing radiation (IR) has been used to treat the various human cancers, IR is cytotoxic not only to cancer cells but to the adjacent normal tissue. Since normal tissue complications are the limiting factor of cancer radiotherapy, one of the major concerns of IR therapy is to maximize the cancer cell killing and to minimize the toxic side effects on the adjacent normal tissue. As an attempt to develop a method to monitor the degree of radiation exposure to normal tissues during radiotherapy, we investigated the transcriptional responses of human peripheral blood lymphocytes (PBL) following IR using cDNA microarray chip containing 1,221 (1.2 K) known genes. Since conventional radiotherapy is delivered at about 24 h intervals at 180 to 300 cGy/day, we analyzed the transcriptional responses ex-vivo irradiated human PBL at 200 cGy for 24 h-period. We observed and report on 1) a group of genes transiently induced early after IR at 2 h, 2) of genes induced after IR at 6 h, 3) of genes induced after IR at 24 h and on 4) a group of genes whose expression patters were not changed after IR. Since Biological consequences of IR involve generation of various reactive oxygen species (ROS) and thus oxidative stress induced by the ROS is known to damage normal tissues during radiotherapy, we further tested the temporal expression profiles of genes involved in ROS modulation by RT-PCR. Specific changes of 6 antioxidant genes were identified in irradiated PBL among 9 genes tested. Our results suggest the potential of monitoring post-radiotherapy changes in temporal expression profiles of a specific set of genes as a measure of radiation effects on normal tissues. This type of approach should yield more useful information when validated in in vivo irradiated PBL from the cancer patients.

This article firstly explores into the concepts, components, and pictures of institutional realization of competition and diversity respectively on the premise that competition and diversity comprise the primary objectives to be pursued by the broadcasting-related laws which provide the concrete measures of media policy, and argues that while the competition objective has differentiation factors, there are also particularities in the diversity value in the broadcasting-related laws as sector-specific competition laws. Then assuming that special competition rules including structural regulatory measures particularly in the broadcasting market are required in order to realize values of competition and diversity harmoniously, this article suggests the following improvement directions for regulations aimed at protection of competition and diversity in the broadcasting-related laws. The first one is with the improvement method for regulations aimed at protection of competition. Regulation on share of audience as an ex ante regulation of status and regulation on prohibited activities as an ex post regulation of conduct may play important roles in substituting the causative regulation while seeking for diversity value. For this purpose, it is needed to develop a concrete method that incorporates diversity-related factors as consideration factors in the standard for determining illegality of prohibited activities by inference to methods of determining illegality in the competition law. The second one is with the improvement method for regulations aimed at protection of diversity. This could be considered from three viewpoints that are the setting of regulatory objectives, the identification of alternative regulatory measures, and the choice of regulatory measures and levels suitable for regulatory objectives. From these viewpoints, the regulatory framework should be improved mainly with institutional measures in which diversity value is used for tools of assessment and analysis, not just remaining as mere rhetorical devices, and whether or to what extent to maintain regulations seemingly unreasonable in terms of harmonization with economic objectives such as competition should be discreetly reviewed.

This study investigated the post-divorce adjustment level, by focusing on life satisfaction, health, stress and resource factors, for divorced men and women in their 20s and 30s. Also, it examined how these factors affect life satisfaction and health. For this empirical analysis, data were collected from 114 divorced men and 112 divorced women, living in the Seoul metropolitan area, from 23rd Sep. to 20th Oct., 2002. The questionnaire for the survey dealt with demographic information, life satisfaction, health, stress and resource factor scales. The major findings of the research project were as follows.: first, the life satisfaction and health levels of the divorced men and women were low. Especially, divorced women had more physical and psychological problems than men. Second, the divorced men's satisfaction was affected by pre-divorce life events and education level, whereas the divorced women's satisfaction was affected by subjective economic dissatisfaction, pre-divorce tfe events, everyday life level when they were divorced, and social support. Finally, the attitude toward divorce of significant others and pre-divorce life events were important variables for the divorced men's health, whereas attachment toward ex-spouse, pre-divorce life events, pre-divorce marital conflict and social support were affectable variables for the divorced women's health. The results of current research are expected to contribute to the divorce adjustment programs according to gender.
