An optimal path generation method considering the safety of UGV(Unmanned Ground Vehicle) is proposed and demonstrated through examples. Among various functions of UGV, real-time obstacle avoidance is a key issue to realize realistic scenario in FCS(Future Combat Systems). A two-dimensional narrow corridor environment is considered as a test field. For each step of UGV movement, two objectives are considered: One is to minimize the distance to the target and the other to maximize the distance to the nearest point of an obstacle. A weighted objective function is used in the optimization problem. Equality and inequality constraints are taken to secure the UGV's dynamics and safety. The weighting factors are controlled by a fuzzy controller which is constructed by a fuzzy rule set and membership functions. Simulations are performed for two cases. First the weighting factors are considered as constant values to understand the characteristics of the corresponding solutions and then as variables that are adjusted by the fuzzy controller. The results are satisfactory for realistic situations considered. The proposed optimal path generation with the fuzzy control is expected to be well applicable to real environment.

The recent Neural Network technique has shown good performance in content generation such as image generation in addition to the conventional classification problem and clustering problem solving. In this study, we propose an image generation method using artificial neural network as a next generation content creation technique. The proposed artificial neural network model receives two images and combines them into a new image by taking color from one image and shape from the other image. This model is made up of Convolutional Neural Network, which has two encoders for extracting color and shape from images, and a decoder for taking all the values of each encoder and generating a combination image. The result of this work can be applied to various 2D image generation and modification works in game development process at low cost.

Recently, most tech-based products are of multiple generations, since new-generation products are replacing the older ones as technologies continue to improve. Although, this means that research is needed to examine as much about the role of post-adoption behavior as the missing link between the adoptions of successive generation as first adoption of innovation, there is a dearth of literature explicitly examining consumers' post-adoption behavior, especially in the context of subscription-based service. For the subscription-based services, in spite of the important role of consumer satisfaction, research on the post-adoption behavior can not carefully examine the direct impact of consumer satisfaction on their decision to upgrade by considering usage instead of satisfaction as the missing link between buyers' first adoption and their next-generation adoption. This study identified two types of attribute satisfaction such as basic attribute and core attribute using both literature review and FGI (Focus Group Interview), and tries to investigate how two types of attribute satisfaction has influence on customers' intention to upgrade to the next-generation services. and a moderating role of customer loyalty between attribute satisfaction and intention. The empirical results show that core-attribute satisfaction has a negative influence on customers' intention to upgrade, due to the moderating role of customer loyalty, but it can raise their intention to upgrade next-generation services. However, basic-attribute satisfaction, on the other hand, appears to positively influence both customer loyalty and the intention to upgrade. We also find that the consumer attribute satisfaction is influenced by consumer innovativeness, her perception of service and the usage of each features' type in different ways. Finally, academic and practical implication is made, limitation is clarified and a direction for further studies is suggested.

The purpose of this research was to find empirical evidence to support the varidity of developing a three generation family apartment as a cultural housing model In Korea. This was done through interviews, a questionnaire mailing survey and the delphi method.Major findings were as follows;There was a string preference for the elderly to live together with their married children, whereas their married children preferred to live independently, being separated from their old parents.Housewives of the younger generation recognized many advantages or good points of the three generation living together. They, however pointed out many disadvantages as well. Most of the good points were related to psychological comfortableness steming from living close each other, while most of the bad points to behavioral constraints steming from living together in one residential unit. This suggested that a new type of heusing, which provides privacy for each generation as well as the feeling of closeness between the two generations, needs to be developed to disseminate positive aspects of the three generation family cuture.There is a concensus among professionals that the three generation family apartment is a promising cultural housing model in korea, especially for the elderly in Korea.

The paper examines the reaction of the Z-Vietnam generation to online TV advertising (TVC), which elements of online TV advertising has a positive influence, which factors do not affect or negatively affect their consumption decisions for the advertised goods. Data for the study was collected from 300 Vietnam's Generation Z in Ho Chi Minh City through live interviews or questionnaires through Google Docs Forms, with over 30 questions. The six basic factors that influence the reactions of Generation Z consumers are information, entertainment, irritation, credibility, interaction, and advertising value. The research results show that, due to the influence of social media and generational characteristics, most consumers of the Generation Z in Vietnam have a favorable attitude towards online TV advertising, and they appreciate this form of advertising. Information element, irritation, credibility and entertainment have a strong and positive impact on TVC. The other two factors are advertising value and interaction, which does not significantly affect the reaction of this generation. This study needs to be checked and reviewed by subsequent studies on a larger scale and in a wider scope because the study only conducted random sampling on a small scale, did not meet the requirements for representation and generality.

The purpose of this study was to explane the Net generation's characters appearing in the apparel brand naming for them. For this study, first I was trying to explane the New generation characters, second 45 apparel brands were selected by market research and questionaire survey was conducted on 53 the Net generation collage women of age 20 thru 21. Third, the apparel brands were classified into four types according to the characters reflecting in the apparel brand naming : First, the apparel brand type using the figures such as STORM=292513, 1492Miles. Second, the apparel brand type that two or more words are abbreviated into one word. Third, the apparel brand type containing more than one meaning in a brand naming or spelling the words as it pronunciate. Fourth, the apparel brand type using of slang. In conclusion, These types of the apparel brands were related to characters of the New generation, i.e., they who have grown in the advance of digital civilization are skilled in the communication through computer, internet and mobile phone, so that they are familiar with the figures, combined words, or abbreviated words etc. Also, they have individual, sensitivity character and seek after individuality, current fashion. They have also a tendency to accept various the sense of value, while they have a refusing tendency a custom or convention which the older generation has conformited.

Objectives: This study was performed to assay the effect of neodymium oxide on the generation of reactive oxygen species and DNA oxidative damage by intratracheal instillation. Methods: Two groups of rats were exposed to neodymium oxide($Nd_2O_3$) via intratracheal instillation with doses of 0.5 mg and 2.0 mg, respectively. At two days and at 12 weeks after exposure, the contents of neodymium oxide in the lung, liver, kidney, heart and brain, leukocyte, olive tail moment, ROS, RNS, lactate dehydrogenase, albumin, cytokine and MDA from BALF were measured. Results: Neodymium oxide contents in the liver, kidney, heart, and brain were detected at less than $1{\mu}g/g$ tissue concentration. However, in the lungs at four weeks the highest amount were detected and then found to be drastically reduced at 12 weeks. ROS and RNS in bronchoalveolar lavage increased in concentration dependently at two days, four weeks and 12 weeks after neodymium oxide instillation. However, ROS and RNS decreased with the passage of time. At two days the total number of WBC in BALF in the high concentration group was significantly increased, and at four weeks the total number of WBC were significantly increased in the low and high concentration groups(p<0.01). At two days after exposure, the LDH of the low and high concentration groups was significantly increased. At 12 weeks, only the LDH of the high concentration group was significantly increased compared to in the control group(p<0.01). As a result of Comet assay, after two days, damage to the DNA of the low and high concentration groups was observed. Conclusions: Intratracheal instillation of neodymium oxide induces the generation of ROS and DNA damage in rats.

These studies were conducted to investigate the development of chemical resistance in two-spotted spider mite (Tetranychus urticae Koch) through alternate selection for a given period of time with four acaricides including ethion of organophophours compound, dicofol of organo-chlorine compound, cyhexatin of organo-tin compound, and biphenthrin of synthetic pyrethroid compound; and to examine multiple-resistance among the acaricides to the selected populations. The development levels of chemical resistance in the two-spotted spider mite were greatly varied under alternate selection with the different chemical-group combination of four acaricides. Resistant levels of the ethion/dicofol-selected population at 13th-13th generation showed 49.4-fold resistance to ethion and 18.1-fold to dicofol; the ethion/cyhexatin-selected population at 9th-9th generation exhibited 28.1-fold to ethion and 5-fold to cyhexatin; the ethion/biphenthrin-selectd population at 10th-10th generation revealed 39.8-fold to ethion and 19.2-fold to biphenthrin. However, the dicofol/cyhexatin-selected population at 9th-9th generation showed 11.3-fold to dicofol and 4.9-fold to cyhexatin, and the dicofol/biphenthrin-selected population at 12th-12th generation exhibited 11.2-fold to dicofol and 9.4- fold to biphenthrin, while the cyhexatin/biphenthrin-selected population at 9th-9th generation revealed 3.7-fold to cyhexatin and 7.7-fold to biphenthrin. In case of alternate selection, the ehtion/dicofol-selected population revealed moderate multiple-resistance level to biphenthrin. The ethion/cyhexatin-selected and the ethion/biphenthrin-selected populations showed low mutiple-resistance level to biphenthrin and dicofol, respectively. However, the dicofol/cyhexatin-selected, the dicofol/biphenthrin-selected and the cyhexatin/biphenthrin-selected populations exhibited high multiple-resistance level to ethion.
