This study aims to investigate the relationship between service recovery justice, residual emotions, and customer behavior. It empirically verifies that low justice in service recovery affects residual emotions and, in turn, has an impact on customers' negative behaviors. Furthermore, this research distinguishes customer-brand relationship quality into emotional relationship quality and cognitive relationship quality and seeks to validate that the type of relationship quality may influence the extent to which the justice of recovery processes affects residual emotions. Data was collected through surveys, and hypotheses were tested using structural equation modeling. The research findings indicate that among the dimensions of service recovery justice, procedural justice and interactional justice significantly influence residual emotions. Moreover, residual emotions have a significant impact on both the intention to revisit and the intention to engage in negative word-of-mouth. In addition, the impact of distributive justice and procedural justice on residual emotions was found to be higher for cognitive relationship quality than emotional relationship quality, and the impact of interactional justice on residual emotions was found to be higher for emotional relationship quality than cognitive relationship quality.

The study, executed with Hallasan National Park, which deserves to be a typical ecotourism destination, aims to provide basic information on park management for early establishment of ecotourism in a national park by assessing its visitors' behavior and satisfaction with a nature trail established as a series of an environmental interpretation program. The questionnaire survey was conducted at Eorimok Square in the weekday and on the weekend for two months of August and September in 2006, and finally 144 valid samples were used for the analysis. As a result of the research, it revealed that the demographic characteristics of the visitors to Hallasan National Park tended to coincide with those of the visitors to other national parks In Korea. On the whole, it showed their low recognition level of nature trails built up in national parks and less experience in using them. However, the visitors' satisfaction level and intention of re-visit, and recommendation to others were comparatively higher after actually using the nature trail at the site of Hallasan National Park, which hints at the possibility of national parks' much weightier role as the ground for ecology education and the functional expansion of the environmental interpretation-related facilities and programs. As for the attributes having effects on users' satisfaction with a nature trail, substantial aspects such as accessibility, safety, uniqueness and interest in environmental interpretation, and educational quality as well as physical facility management were revealed to have equal effects on users' satisfaction level, so there still remain a lot of pending issues over the reality of national parks in the initial stage of ecotourism staying at the level of the introduction and establishment of the facilities for environmental interpretation. This research had surveyed visitors to Hallasan National Park and limited to the nature trail only. For more systematic and practical ecological management of a national park, the in-depth understanding of the attributes affecting satisfaction of ecotourists, including nature trails and other environmental interpretation programs, and more sophisticated measuring tools are needed.

One type of innovative multimedia platform environments is mobile data services (MDS), exemplified by Nate, Show, and OZ. In the context of MDS, enhancing user's continuance intention is a significant challenge to the continuing growth and long-term viability of MDS. Because the cost of using MDS is borne mainly by users, they are likely to evaluate it based on perceptions of what is received and what is given. This study identifies perceived usefulness and perceived enjoyment as the 'get'components, and perceived fee and perceived anxiety as the 'give' components. To understand the role of get and give components in the MDS post-adoption environment, this study incorporates these components into expectation confirmation model. We collected data from 204 users who had direct experiences with MDS within recent 3 months. The data was analyzed by employing PLS (partial least squares). Theoretical and practical implications of our findings are discussed.

Purpose: This study aims to identify factors that influence middle-aged men's attitude towards death. Methods: The study enrolled 204 middle-aged (range=40~59 years) male residents of Daegu in Korea. Using a structured questionnaire, data were collected in October 4~30, 2010. For data analysis, we used descriptive statistics, t-test, one-way ANOVA, Scheff$\grave{e}$'s test, Pearson correlation coefficient, and stepwise multiple regression with SPSS WIN 14.0. Results: Participants' attitude towards death significantly differed according to educational level, religion, volunteer activities, and perceived health status. Moreover, their attitude towards death was negatively correlated with life stress and depression and positively correlated with self-esteem, life satisfaction, and coping behavior. The factors influencing the attitude towards death were life satisfaction, daily stress, religion, and depression, which explained approximately 25.7% of the total variance. Conclusion: Middle-aged men perform a crucial role in our society, and their attitude toward death affects how they cope with a situational crisis such as a terminal cancer or withdrawal of life sustaining treatment. Therefore, it is necessary to develop and implement a support program for middle-aged men, which offers them with various strategies to better manage their daily stress and improve their life satisfaction and coping skills.

Little investigations have been carried out to study the shear behaviors of RC beams with recycled aggregates. So, this experiment investigates the shear performance and suggests the possible application of Recycled Concrete Aggregate (RCA) for building structures. In general, shear strength of reinforced concrete beam without stirrups is dependent on the compressive strength of concrete, the longitudinal steel ratio, and the shear span-to-depth ratio. In this study, total 28 recycled aggregate concrete beams without shear reinforcement were tested by two-point load and all beams were singly reinforced. The variables studied in this investigation are shear span-to-depth ratios (a/d=2, 3 and 4), RCA replacement ratios (0, 15, 30 and 50%) and longitudinal steel ratios (0.80, 1.27 and 1.84%). The designed concrete compressive strength with a 30 MPa is used. This research will play an important role toward the establishment of the structural design standard for RCA concrete.

In this paper, a neural network approach to forecast Korean regional precipitation is presented. We first analyze the characteristics of the conventional models for time series prediction, and then propose a new model and its learning method for the precipitation forecast. The proposed model is a layered network in which the outputs of a layer are buffered within a given period time and then fed fully connected to the upper layer. This study adopted the dual connections between two layers for the model. The network behavior and learning algorithm for the model are also described. The dual connection structure plays the role of the bias of the ordinary Multi-Layer Perceptron(MLP), and reflects the relationships among the features effectively. From these advantageous features, the model provides the learning efficiency in comparison with the FIR network, which is the most popular model for time series prediction. We have applied the model to the monthly and seasonal forecast of precipitation. The precipitation data and SST(Sea Surface Temperature) data for several decades are used as the learning pattern for the neural network predictor. The experimental results have shown the validity of the proposed model.

This study is to study Adler's individual psychology and to study the counseling process and counseling techniques based on the counseling theory derived there. The progress of Adler's consultation process is first, and the relationship formation phase is the phase of seeking equal and mutually cooperative relations working as active partners toward agreed objectives between the counselor and the counsellor. Second, the lifestyle search phase is an important goal to understand lifestyle and how lifestyle affects life's task. Third, the insight phase is the one that has insight. Fourth, it is carried out in the financial direction (transformation of behavior). Adler's counseling techniques include general techniques and special techniques, and general techniques include promptness, advice, encouragement, paradoxical intentions, demonstration of poetry, and role play. Special techniques include pressing a doorbell, spitting on a physician's soup, Midas technique, entertaining others, avoiding low-quality children and self-restraint. In conclusion, individual psychological counseling is based on growth model, not medical model, and has more interest in re-education and re-lighting healthy individuals and societies than on the aspect of treatment. Therefore, it applies to various areas such as child guidance centers, parent-child counseling, marital counseling, family counseling, group counseling and treatment, personal counseling for children and adolescents, cultural conflicts and mental health campaigns.

In order to investigate the structure and dynamics of atatic poly (vinyl alcohol) (PVA)/water system, laser light scattering experiment has been done in the semi-dilute concentration regime at $25^{\circ}C$. The scattering intensity I(q) can be analyzed with the fractal equation of $I(q){\sim}q^{-m}$ instead of Onstein-Zernike type equation. The fractal dimensionality m was found to be constant after reaching the plateau value of $m=2.6{\pm}0.3$ above C=3wt%. The time correlation function of dynamic light scattering has always two different modes such as fast mode and slow one. The cooperative diffusion of fast mode showed concentration independence contrary 4o the reptation theory's concentration dependent exponent of 3/4. The slow mode can be interpreted as the motion of large scale heterogeneities and its strong concentration dependence is apparent with a large negative exponent of -3.0. It is considered that the stereo-regular arrangement with four successive meso units of -OH plays as a key role in forming such heterogeneity.

Four kinds of N,O-hydroxypropyl chitosans (HPCTOs) with degree of substitution(DS) and molar substitution (MS) ranging from 2.47 to 2.52 and 4.9 to 7.8, respectively were synthesized, and their molecular chracteristics and thermotropic and lyotropic liquid crystalline properties were investigated. MS was exceedingly larger than DS, showing that in the later stages of reaction, propylene oxide was preferentially added to the side chains rather than the main chain. All the derivatives formed thermotropic cholesteric phases. The glass and clearing temperatures were decreased with increasing MS. The optical pitches (${\lambda}_m$'s) of the thermotropic cholesteric phases increased with temperature. However, the ${\lambda}_m$'s of the derivatives at the same temperature increased with increasing MS. Solutions of HPCTOs in water, methanol, ethanol, acetic acid, and formic acid containing more than 30 wt% polymer also formed cholesteic phases whose ${\lambda}_m$'s decreased exponentially with increasing polymer concentration. The concentration dependence of ${\lambda}_m$ of HPCTO solutions, however, highly depended on the nature of the solvent and MS. The thermotropic and lyotropic mesophase properties of HPCTOs were significantly different from those reported for hydroxypropyl celluloses. The results indicate that the secondary amino group in the C-2 position plays an important role on the formation, stabilization, and temperature and concentration dependencies of ${\lambda}_m$ of the cholesteric mesophase.

Two kinds of N,O-hydroxypropyl chitosans (HPCTOs) with degree of substitution (DS) and molar substitution (MS) ranging from 2.15 to 2.39 and 2.9 to 4.1, respectively, and five kinds of aliphatic acid esters of HPCTOs (HPCTOAms, m=0,2,4,7,9, the number of methylene units in aliphatic substituent) based on the HPCTOs were synthesized, and the thermotropic liquid crystalline properties of the derivatives were investigated. All the derivatives formed enantiotropic cholesteric phases whose optical pitches (${\lambda}_m$'s) increased with increasing temperature. However, the glass and clearing temperatures, the magnitude of ${\lambda}_m$ of the mesophase at the same temperature, and the temperature dependence of ${\lambda}_m$ of the investigated derivatives highly depended on MS and m. The thermotropic mesophase properties of HPCTOAms were significantly different from those reported for the aliphatic acid esters of hydroxypropyl celluloses. The results indicate that the secondary amino group in the C-2 position plays an important role in the thermal stabilization and temperature dependence of ${\lambda}_m$ of the cholesteric mesophase.
