This study was conducted to find out the characteristics of H University's students admitted through affirmative action program. The differences between the affirmative action program enrollment students and all students were compared by descriptive statistics and correlation analysis methods. In addition, in-depth interviews were conducted for students who entered the affirmative action program. A qualitative research method was used to analyze the contents of in-depth interviews. The results of the study are as follows. First, the higher the entrance score, the higher the university score for students in the affirmative action program. Second, the college satisfaction of students entering the affirmative action program is higher than that of students enrolled. Third, according to the results of the in-depth interview, the affirmative action program students were both active and not. In conclusion, it is necessary to establish a system in which students can actively prepare for their careers in universities. Accordingly, the expansion of the affirmative action program is likely to contribute to the development of universities.

On-line clothes sale are on the increase, and the returns(for replacements or refunds) of the clothes are also increasing. Many studies on off-line consumers' complaints were made before, but few studies on the returns of clothes sold on-line have been made. From this viewpoint, this study was conducted to know what effect returns of clothes sold on-line have on their brands. Therefore, this study was first focused on the factors affecting complaint acts(return intention or return acts) such as lack of information and recognition of product, delivery errors and product defects concerning on-line sales, and second investigated the changes of buyers' attitude toward the brand following the their acts of returning the buyers, and third looked into the changes of on-line buyers' attitude toward the brand. The study is carried out by subdividing the objects of the study into return action(replacement, refundment) and purchasers who experienced return intention. Such experience is demonstratively analyzed to find how it has affected the attitude toward the brand. The study comes up with the following outcomes. First, the effect factor causing complaint action(return action, return intention) on-line is shown as the lack of the information and recognition of the product. Second, it is revealed that the effect factor causing complaint(return action, return intention) does not lie in an error in delivery or a defect of a product. Third, the positive response of a brand to a return action does not raise the repurchasing intention and positive attitude of purchasers who experienced returning a product, but lowers their private complaint action intention. Fourth, the repurchase intention of purchasers who experienced return intention for the brand is lowered, but their negative attitude and private complaint action intention is not raised.

The study is a user experience design study on the function of action cams used for leisure activities that have been on the rise recently. Along with the video platforms that are developing in a user-friendly way, the size of the action cam market is also growing. However, there is a lack of research on the quality of a function that enhances the user experience. Thus, this study classified action cam functions according to user experience elements by using Kano Model's analysis method and in-depth interview, and analyzed how the quality of action cam functions affects the user experience by conducting a satisfaction survey by function. The results of the study have shown which functions should be improved first and which functions should be continuously researched and invested. I hope this study will contribute useful information to developing user-centered action cams.

Methods of Riemannian geometry has played an important role in the study of compact transformation groups. Every effective action of a compact Lie group on a differential manifold leaves a Riemannian metric invariant and the study of such actions reduces to the one involving the group of isometries of a Riemannian metric on the manifold which is, a priori, a Lie group under the compact open topology. Once an action of a compact Lie group is given an invariant metric is easily constructed by the averaging method and the Lie group is naturally imbedded in the group of isometries as a Lie subgroup. But usually this invariant metric has more symmetries than those given by the original action. Therefore the first question one may ask is when one can find a Riemannian metric so that the given action coincides with the action of the full group of isometries. This seems to be a difficult question to answer which depends very much on the orbit structure and the group itself. In this paper we give a sufficient condition that a subgroup action of a compact Lie group has an invariant metric which is not invariant under the full action of the group and figure out some aspects of the action and the orbit structure regarding the invariant Riemannian metric. In fact, according to our results, this is possible if there is a larger transformation group, containing the oringnal action and either having larger orbit somewhere or having exactly the same orbit structure but with an orbit on which a Riemannian metric is ivariant under the orginal action of the group and not under that of the larger one. Recently R. Saerens and W. Zame showed that every compact Lie group can be realized as the full group of isometries of Riemannian metric. [SZ] This answers a question closely related to ours but the situation turns out to be quite different in the two problems.

This study analyzed the effect of consumer value and unethicality on the type of consumer complaint behaviors. Despite the obvious importance of the research on consumer complaint behaviors focused on consumer's inherent personality, there is relatively little work done. The purpose of this study is to analyze the determinants of consumer complaint behaviors in order to improve consumers' well-being and develop the market condition. The 1,050 respondents are finally analyzed using the descriptive statistics, factor analysis, and multinominal logit model. Consumer value and unethicality are significant effect on the type of consumer complaint behaviors such as no action, private action only, public action only, and both private and action. The orientation of achievement and pleasure among consumers' value is associated with the higher level of complaint behaviors compared with no action. In terms of consumers' unethicality, no harm unethicality is associated with the types of each consumer complaint behavior except no action. On the other hand, both proactive and passive unethicality increase the possibility of no action. The policy implications of the consumer education are suggested as well as the directions of customer management strategies in the business sector.

Purpose: This study examined the effects of the type of video contents used for action observations on the ability to control posture. Methods: The participants were 48 healthy adults. The two hands of the participants were crossed on both shoulders, and the other foot was placed in a straight line in front of the target to allow them to watch a video of the monitor. The videos were presented in random order with three video contents (natural, stable balance posture, and unstable balance posture) consisting of 30 seconds each. A 15-second resting time was given between each video. During action observation using various video content forms, the posture control ability was measured using a TekScan MetScan^® system. Results: The results revealed statistically significant differences in the area of movement and the distance by COP and distance by the type of action-observation videos, and the distance by the anteroposterior and mediolateral sides (p<0.05). The stable balance posture and unstable balance posture video showed significant differences in the distance by the COP, anteroposterior, and mediolateral distance. (p<0.05) Conclusion: This study suggests that choosing the contents of the videos is important during action-observation training, and action-observation training can help improve postural control.

The durability of concrete involves resistance to freeze-thaw action, corrosion, permeation, carbonation, chemical attack and so on. Generally, properties of concrete have been well understood under the separate action of these deterioration mechanisms. However, in practice, the degradation of concrete usually is the result of combined action of physical and chemical attack and can be accelerated by the combined action of several deterioration mechanisms. In the present study, to evaluate the combined deterioration by freeze-thaw action and seawater attack, ground granulated blast-furnace slag or silica fume concrete with water or seawater as mixing water was exposed to 210 cycles of freeze-thaw action. Tests were conducted to determined the relative dynamic modulus of elasticity and compressive strength. Furthermore, The XRD, SEM and EDS analysis were performed on the deteriorated part of concrete due to freeze-thaw action and seawater attack.

This study was performed in order to certify the antidiuretic action and to investigate the mechanism of antidiuretic action of debrisoquin infused into a renal artery in dog. Debrisoquin, when infused into a renal artery, exhibited the antidiuretic action accompanied the reductions of glomerular filtration rate and renal plasma flow, and the decreased amounts of sodium and potassium excreted in urine, limited only to the infused side, while control kidney function remained unchanged at all. The antidiuretic action of debrisoquin infused into a renal artery was blocked by pretreament of prazosin, $\alpha$$_1$-adrenergic blocking agent, or reserpine, catecholamine depleting agent. These results suggest that debrisoquin infused into a renal artery elicits antidiuretic action through indirect stimulation of renal sympathetic nerves.

Based on the reinterpretation of the well-known relationship between shear and the rate of change of bending moment in a reinforced concrete beam subject to combined shear and moment loads, the shortcomings of present truss models are discussed. The core of the theory is that a new perspective on the shear strength can be gained by viewing the internal stress filed in terms of the superposition of two base components of shear resistance; arch action and beam action. The arch action can be designed using the simple truss having curved compression chord, while the beam action between the two chords can be modeled using a parallel chord truss with MCFT or RA-STM. The compatibility of deformation associated to the two action is taken into account by employing a characteristic factor a. The new model was examined by the Stuttgart beam shear tests, and the results show that the present approach provides good estimates of stirrup contribution and concrete contributions.
