Traffic broadcasting is using a usual traffic information announcement when giving its information to users on the road and for the provision of information useful to drivers, a clear criteria of how to judge with information from informers needs to be established from the perspective of users. In this study, to give some available criteria for current announcement which often causes confusion, cognitive characteristics were investigated and analyzed based on judgment criteria which are commonly felt by correspondents, participants in traffic broadcasting and drivers. The result requires the provision of information that is relied on an average speed where drivers feel little cognitive difference and found a classification where a smooth traffic flow is more than 60km/h, going slow 40~60km/h and congested state less than 40km/h respectively. And from the study of 35 traffic information announcement for different traffic situations, 8 cases of smooth state and 9 cases of congested state were clearly classified but the rest 18 cases of comment were ambiguously perceived by drivers and which requires the necessity of a announcement that uses directly the word of 'smooth', 'slow', and 'congestion' in the actual expression of slow driving. The future study should be focused on the establishment of more definite criteria by representation of nearly real traffic flow, provision of traffic information announcement and the analysis of cognitive response through car dynamic simulators and the kinds.

This paper is intended as an investigation of relation between pre-service kindergarten teacher's creative personality and teacher's efficacy. Subjects of this study were 160 third grade students of S collage & Y collage. They were major in infant or early childhood education and have an field practice experience of nurture and education. Tool for measurement is Creative Personality Scale of Ha Juhyun and TEBI(Teaching Efficacy Belief Instrument) teacher's efficacy test which is modified by Kim Sunnam. The collected data were analyzed by one-way ANOVA, post hoc Scheffe' test, Pearson's correlation and stepwise regression. The following results were obtained. First, there is no difference in creative personality according to academic grade, age, experience of leadership in collage. Second, there is a static relation between age of pre-service kindergarten teacher and teacher's efficacy especially personal teacher's efficacy. Third, points of creative personality is relative to teacher's efficacy, especially relative to personal teacher's efficacy. Among the sub-factors of creative personality, factors estimates teacher's personal efficacy are 'self belief, imagination and open mind'. On these ground, I comment on curriculum which will educate creative personality of pre-service kindergarten teacher.

The purpose of this study is to investigate the educational validity of EBS education broadcasting. The purpose of science education is not only to improve metacognition, but also to make student acquire scientific knowledge. So, this study present the question of whether EBS education broadcasting could raise students' metacognition or not. At ㅂ highschool, the VOD texts provided by EBS education broadcasting was used for all curriculums including science in 2002 and 2003. It was accepted that the model wpuld be using considered VOD texts as materials and focusing on students' voluntary acting. But the students couldn't be given a stimulus raising metacognition by these models. The metacognition such as metaknowledge, metaexperience, and monitoring must be mediated during school hours for valuable science lessons. First, the manipulation such as teacher's pertinent question or comment reminding students about the materials was connected with teaming subject. Second, it is important for students to do an analogical experiment in odor to experience the reality. Third, feedback and the scripts of students' conversation must be given to students to monitor their own learning process.

Luminescence is a physical phenomenon exhibited by many non-conducting, crystalline materials, such as quartz and feldspar. Within the crystals, energy absorbed from ionising radiation frees electrons to move through the crystal lattice and some are trapped at defects in the lattice. Observable luminescence is produced by electrons, released from traps by stimulation by absorption of light, which recombine with lattice defects which act as luminescence centers - optically stimulated luminescence (OSL). In a similar way to thermoluminescence(TL) dating, controlled measurement of the OSL signal can provide a means of determining the time since the last exposure of a layer of sediment to sunlight, the age of the sediment. However, whereas in the thermoluminescence dating of sediment only part of the latent thermoluminescence signal is bleached by sunlight as the sediment is deposited and allowance must be made during the laboratory measurements for the light insensitive component, optically induced luminescence dating has the advantage of working only with light sensitive traps in the crystal. Determination of the time since deposition of Quaternary sediment samples from the OSL of quartz grains using blue light was performed. A series of experiments and recent developments relating OSL dating are described, beginning by identifying the features which make OSL signals suitable for the development of dating method. Additionally, there are suggestions as to future research for obtaining reliable ages and a comment on current best practice on procedures, with the dating results of Quaternary sediment.

This study selected a case study method conforming to qualitative research in order to analyzed how each type of fashion enterprises uses SNS in-side of fashion marketing based on content the researcher monitored and selected from the Facebook website for each enterprise. The standard to select fashion brands in this study is a graded list made based on ranking 5 analysis sites on social media (Socialbakers, socialDigm, Pulse K, BigFoot9, L2). The researcher sorted and then analyzed 2 brands that have many fan joiners and followers among fashion brands that were ranked top of the graded list, work in Facebook animatedly, and had representativeness in each type (SPA, Sports Brands). The study was conducted from January 2013 to March 2013, and the index of Facebook consisted of 3 kinds of elements (comment, like, and share). Each numerical value was counted to decide the monthly ranking. Content analysis was divided into public relations about brand, public relations about products, and customer participation and activities; consequently, the researcher investigated which content was post conforming to the ranking. The study analyzed the analysis results of each brand derived through the method of study compared to other brands. The results are as follows. In case of SPA brands, the category accounting for high rank in index analysis are public relation events to attract customer attention and products and offering information. The results of the monthly trend about whole post category were also similarly analyzed so the promotion goal that the brand wants to seek in priority coincides with the customer compliance rate. Next, in the case of sports brand, public relations for products offering information, event for arousing customer concern, and participation activities accounted for a high rank in the index analysis and posted the most in the analysis of the monthly trend for whole post category. The researcher came to understand that the direction of content for brands shown through Facebook coincides with customer sympathy.

The "Tai Su(太素)" which was published by Yang Shang Shan(楊上善) during the Tang(唐) dynasty does not follow complicating hand down procedures allowing it to be preserved in a relatively satisfactory state, and the book is evaluated as a major article in the study of the "Yellow Emperor's Internal Classic(黃帝內經)" in the modern age. The book of "Tai Su explanation of channel diseases(太素 經脈病解)" offers the detailed description of disease symptoms found in the book of "Miraculous Pivot channels(靈樞 經脈)", and Yang Shang Shan(楊上善) provided relatively complete explanations from the perspective of the wane and wax of shadow and sunshine powers(陰陽消長). The present writing was projected to acknowledge the relationship between the books of "Tai Su explanation of channel diseases(太素 經脈病解)" and "Miraculous Pivot channels(靈樞 經脈)" and substantially attempted to understand the original text of the "Tai Su(太素)" by adopting the perspectives of Yang Shang Shan(楊上善) in explaining the disease symptoms as he attempted in the book of "Miraculous Pivot channels(靈樞 經脈)". Total 50 disease symptoms were explained in the book of "Tai Su explanation of channel diseases(太素 經脈病解)", and 33 of them are common to the symptoms described in the book of "Miraculous Pivot channels(靈樞 經脈)" by taking up about 66% of the book. The monthly attachment(月別配屬) of three shadow and three sunshine power(三陰三陽), which is described in the book of "Tai Su explanation of channel diseases(太素 經脈病解)" provides an important clue in understanding the exterior and interior(表裏) relationship, and the crucial perspective lies on the mutual intensity change of shadow and sunshine powers. Therefore, the monthly attachment of three shadow and three sunshine power provided by the present article helps to understand the meaning of the three shadow and three sunshine power along with the time attachment(時間配屬) described in the other chapter of the "Yellow Emperor's Internal Classic(黃帝內經)". In the method of explaining pathogenesis, the explanation was made by understanding the perspective of mutual intensity change of shadow and sunshine powers, and exterior and interior relationship along with the channel Path(經脈流注) have been used simultaneously. In the comment of the main article, Yang Shang Shan(楊上善) stated the channels of hands and feet(手足經脈) as the scope of the three shadow and three sunshine power, but the symptoms and signs are mainly focused on the channels of feet as in the book of "Miraculous Pivot channels(靈樞 經脈)".

Objectives : School refusal is usually considered as individual's behavioral problem. These days. however. the adolescents' school refusal needs some kind of medical approaches because it is related to mental disorder of the adolescents. Due to too much pressure and stress from the competition between classmates and from good performance in school. the number of adolescents who refuse to go to school is increasing. Despite this circumstance. school refusal is neither regarded as a single independent disorder nor endorsed as an officially classified disease. which makes difficult to conduct research on this issue and to establish standardized treatment for it. In addition. there is a lack of research on this topic. especially in oriental medicine. so there is no a case report or study on school refusal. This study is trying to comment on school refusal from the perspective of oriental medicine. Methods : We tried to examine the effect of oriental medicine treatment for school refusal with four adolescent cases. The patients commonly have at least more than one mental disorder (including depression disorder. anxiety disorder. and anorexia nervosa). have some problem with the relationship with their family. in particular with mother. do not have father or not be loved by their father. and have irregular eating habits. Thus. we diagnosed them as qi transforming into fire (氣鬱化矢) spleen-stomach deficiency cold (脾胃虛寒) and heart blood deficiency (心血虛) due to stress from the family issues and unhealthy eating habits. The patients received supportive therapy. family therapy. etc among many oriental mental treatments and their progress had been observed through hospitalization and outpatient treatment. Results : All four cases were reported positive progress on their symptoms and started coming back to school. We also examined whether they were well fitting into the school while they received outpatient treatment. and the results show that all four patients continue to settle down in normal school life. Conclusions : This study closely reviewed the mental disorder of school refusal cases and showed that the Oriental medical treatment was effective in helping the patients come back to school. More future research is required to better treatment for school refusal cases in oriental medicine.

Social networking services (SNS) are developing significantly with the Internet and smartphones. It's a friendly social media, but if you think deeply about it, you'll find that it has a variety of faces. It is a communication tool between users, a medium for delivering information, an infrastructure for providing applications, and a community where people with common interests gather. In recent years, business tools, shopping and payment methods are also being swallowed. The influence of the spread of SNS on the real world is also expanding, and the work being dealt with from a sociological perspective is also increasing. Also, if you pay attention to the technical aspects of SNS, it is composed of various technical elements, such as infrastructure that handles large-scale access, user interface that supports comfortable use, and big data analysis to understand people's behavior more deeply. However, I usually use it as usual. However, if you look through SNS, you can see that the situation is surprisingly profound and multifaceted. This study began by looking at the history and current status of SNS and attempted to find its status through comparison with other media. From the point of view of relationship with society, it can be a risk and legal issue when using SNS, such as crimes using bad social media or social media. It is also necessary to comment on the activities on SNS or the guidelines established by the operators. Therefore, various legal issues on SNS will be discussed. Also, as an example of using SNS, I will introduce an example of using SNS in disaster response. From a more technical point of view, you will receive commentary on SNS's network-based technology and SNS's information use, and these articles will help you understand and use SNS safely and help you further utilize or develop SNS.

Tortillas were prepared using rice and wheat flour. The experimental design incorporated thee independent variables(rice, wheat flour and moisture content) producing 14 samples of different proportions of each variable for each tortilla. The following were analysed using Design Expert 6 to unveil the influences of these variables on tensile strength and color(L, a, b). Results indicated that tensile strength increased with increasing rice and wheat flour content, however, decreased with increasing moisture content. Lighteness(L), of the tortilla increased with increased rice content whereas yellowness(b) increased with increased wheat flour content. The model suggests that tensile strength and color(L, a, b) in tortillas are highly correlated(SD Comment - give correlation coefficient and p-value). As well, the numerical optimization method suggests that the ratio of wheat flour to rice flour to moisture content which maximizes the three responses(tensile strenth, L and b) is 18.26 : 33.92 : 39.24%, 28.15 : 25.77 : 37.50%.
