Currently, attentions toward the Chinese market have been growing rapidly. Economical values of China are highly appreciated. The current shift of economical environments in China leads to changes in the way of consumers' consumption. The purpose of this study is to identify the Chinese consumers' brand purchasing behavior according to their lifestyle. Questionnaires developed by researcher were distributed and collected from 118 Chinese consumers living in metropolitan areas of China. In research, five different lifestyles were identified; which are the vogue pursuing group, the social intercourse group, the traditional conservative group, the achievement pursuit group, and the passive stagnated group. These groups differed in the perception of cosmetic prices, purchase motivations, post-acquisitional satisfaction, and their demographics. For example, the vogue pursuing group consumers turned out to consider price as the most important element when they purchase cosmetics, while the social intercourse group valued recommendation from others more. Meanwhile the traditional conservative group and the achievement group each used past experience and attributes as their criterion.

The age and growth of the blackthroat seaperch Doederleinia berycoides was investigated based on samples captured in the southern seas of Korea from January to December, 2006. Age was estimated by analyzing otolith growth rings. The spawning period was extrapolated from August to November based on monthly changes in the gonad somatic index. The relationship between total length and otolith radius was analyzed separately for each sex with TL=-15.6174+10.3274R for females and TL=-4.4083+7.0749R for males. From the parameters calculated using average total length and weight when the year ring was formed, the growth of D. berycoides was expressed by von Bertalanffy growth equations as $L_t=34.71(1-e^{-0.2557(t+0.2078)})$, $W_t=713.85(1-e^{-0.2557(t+0.2078)})^{3.1972}$ for females, $L_t=27.37(1-e^{-0.3388(t+0.7362)})$, $W_t=353.91(1-e^{-0.3388(t+0.7362)})^{3.1647}$ for males, and $L_t=34.20(1-e^{-0.2530(t+0.2871)})$, $W_t=674.10(1-e^{-0.2530(t+0.2871)})^{3.1171}$ for pooled sexes, where L is total length at age t.

The purpose of this review was to investigate feasibility of intensive virtual reality training to improve upper extremity function with brain plasticity of individuals with stroke through the literature. The recovery of the paretic upper extremity depends on regularity and intensity of training as use-dependent plasticity. In resent, virtual reality program has been widely used in the occupational therapy field of augmented stroke rehabilitation. There is a growing body of evidence that virtual reality training of the paretic extremity induces brain plasticity associated with motor improvement. In terms of therapeutic feasibility to improve paretic upper extremity, recent research has explored several important factors of virtual reality training for recovery of upper extremity motor function. These factors include high repetition intensity, high motivation like type of game, enhanced multisensory feedback regarding performance, and interactive task-oriented training. Therefore, occupational therapy combined with intensive and repetitive virtual reality training will enhance recovery of upper extremity motor function after stroke.

The coffee market has been rapidly growing up recently as well as the coffee industry which makes the number of educational institutions increasing in Korea. On the other hand, the classes lean too much on the practical exercise so the coffee education is urgently needed to define precisely and systematize academically. This study is accomplished on the basis of the teachers and students requirement analysis. The features that sets this study apart from the existing educational digital media is that the definite teaching-learning methods and teaching strategies were developed first. Furthermore, the physical and chemical phenomenon of coffee brewing were simulated by 3D animation software based on the visual languages. The general process of this media production was composed by the mutual relationship of the teacher's needs, educationist's strategies and media producer. After applying the digital media to students in the lesson of coffee science theory it was effective to increase their concentrativeness, interesting and learning motive. This media is also receiving the positive evaluation by the teachers to help the students in understanding the coffee science.

The purpose of this study was to investigate whether there was a gender difference in motivating university students to decrease their sodium intake and to identify effective motivating factors. Within the protection motivation theory (PMT) framework, a survey questionnaire was developed to measure participants' perceptions on the severity of and the vulnerability to risk of serious diseases due to the high sodium intake, as well as the effectiveness (response efficacy) and the ability to perform preventive measures (self-efficacy). Behavioral intentions on five specific practices (checking nutrition label, consuming more fruits and vegetables, consuming less soups, avoiding spicy and pungent food, purchasing less instant or restaurant foods) related to decreasing sodium intake were also included. A total of 294 usable response data were collected from university students (92 male, 202 female) in Busan and Gyeongnam in June 2015 and analyzed using IBM SPSS 22. Severity was the highest (4.04) PMT factor followed by response efficacy (3.72), self-efficacy (3.42), and vulnerability (3.26). Compared to male students, female students thought that the threat was more severe (t=6.035, p<0.001) and reducing sodium intake would be effective to prevent serious illnesses (t=4.724, p<0.001), but their vulnerability and self-efficacy perceptions were not different from male students. Among the five items measuring behavioral intention, female students were more likely to increase fruits and vegetables consumption (t=3.811, p<0.001), while male students were more likely to avoid spicy and pungent foods (t=2.336, p=0.020). Based on findings of this study, the recommended strategy to effectively motivate university students to lower their sodium consumption level is the development of campaign focused on increased vulnerability perception, response efficacy, and ease of practicing preventive measures instead of emphasizing the severity of the consequences.

This paper is to explore the effects of Robot Based Instruction(RBI) on improving immersion learning. According to our research, we found out that there is significant improvement in learning immersion and there's 9 sub-factors score after RBI was applied. Also from the result that there is no significant difference between male and female students in learning immersion score, we can found that RBI can improve the learning immersion of students regardless of the learner's sex. The result of verification on the learning immersion is difference by subjects showed that there is significant improvement only in korean, science, art subject among 7 subjects. The above-mentioned results are based on as follows two reasons. First, RBI is efficient to improve students' internal motivation and ownership about tasks, and that is related to environment of learning and instruction focused on authentic task and practice. Second, educational advantages of robot media was reflected appropriately in RBI, also appropriate instructional environment for RBI was supported.

Reproductive biology of the naked-headed goby, Faronigobius gymnauchen was investigated by means of histological methods. The ovary was consisted of several ovarian lamellae and the oogonia originated from the inner surface of the ovarian lamella. The testis was seminiferous tubule One in internal structure. Seminiferous tubule was consisted of many testicular cysts which contained numerous germ cells in a same developmental stage. The size of group maturity was 4.5 cm intotal length. Gonadosomatic index(GSI) of the female and male was the highest in June and July, respectively. Reproductive cycle could be classified into the growing ($January{\~}March$), maturation ($April{\~}May$), ripe and spent (June{\~}July$), and recovery and resting ($August{\~}December$). Oocyte development was group-synchronous, and yolk nucleus was observed in the early growing oocyte.

The service which is required wide bandwidth is growing in these days, so building up High Speed communication system is being required. The Task Force team of IEEE 802.3ah set the EPON as a standard; next generation subscriber access network. For offering a high quality service, 10G EPON that is changed from 1Gbps uplink downlink bandwidth to 10Gbps is come up. Although Kramer had studied 10G EPON there was a QoS limitation, when load is low, End-to-End maximum delay is increased. This paper is suggesting time synch ronization method, resource reservation method, band width allocation method. We confirmed that 10EPON was able to offer quality service by the result of the OPNET.

The amount and frequency of past experience in forest recreation have been considered as one component of an overall specialization. Past research has shown that more specialized recreationists have differing motives, attitudes, satisfaction levels, environment preferences, and management preferences. The overall purpose in this study was to investigate the effect of specialization on users' attitudes toward environment and park management. 320 Wolaksan visitors were surveyed in the summer of 1993 to collect the data. Specialization, as measured by past experience, frequencies of visitation to any forest recreation areas per year, visitor days per year, and number of visits to Wolaksan, was tested the relationship to the users' levels of environment attitudes and park management perception. Among the specialization variables, past experience was highly correlated with the levels of attitudes toward environment. Experienced recreationists preferred natural environments to settings associated with social activities. Most of respondents perceived the importance of the attributes related to park management. However, they gave low performance scores to the attributes.
