  • This study will be an exploratory study from the perspective of IWOM on the intention of word-of-mouth transmission. And based on 256 questionnaire survey data of E-Commerce live broadcast consumers, structural equation modeling is used to explore the paths and mechanisms of influence of consumers' perceived IWOM and perceived value on oral transmission intention in China's E-Commerce live broadcast. The results found that consumers' perceived IWOM had a positive effect on perceived usefulness and perceived entertainment, and that perceived usefulness had a positive effect on purchase intention while perceived entertainment had no direct effect on word-of-mouth transmission intention. Perceived IWOM also indirectly influences willingness to pass on word-of-mouth by affecting perceived value. Among them, the mediating effect of perceived usefulness in the path of perceived network influence on word-of-mouth transmission intention is greater than that of perceived entertainment.

  • QoE is defined as a quality perceived by users on a certain service. However, standard method to measure voice QoE(MOS) has been developed, but no standard method to measure video QoE has been defined. In this paper, we propose an efficient algorithm to measure video QoE s automatically for IPTV services. The proposed method selects candidate scenarios that affect the users' MOS directly, and derives weight factors for the selected scenarios. With the weight factors for the scenarios, video QoE value is calculated. For the validation of the proposed algorithm, we made degraded videos reflecting the parameters. With the degraded videos, by comparing the user perceived MOSs with the video QoEs derived by the proposed algorithm, we show that the two values are highly correlated each other.

  • This paper is concerned with the problem of existence of solutions to the initial value problem u'(t) = A(t, u(t)), u(a) = z in a probabilistic normed space where $A : [a,b)\;{\times}\;D->E$ is continuous, D is a closed subset of a probabilistic normed space E, and $z\;{\in}\;D$. With a dissipative type condition on A, we estabilish sufficient conditions for this initial value problem to have a solution.

  • The paper deals with characterization of standard Gumbel distribution and standard $Fr{\acute{e}}chet$ distribution and was motivated by [4], where the Weibull distribution is characterized. We present criterions using the independence of some suitable functions of lower records in a sequence of independent identically distributed random variables $\{X_n,\;n{\geq}1\}$.

A Study on the Objectives of Cultural Property Education for establish of the U.V.E.C.(Understand, Value, Enjoy, Create) Cultural Property Education (U.V.E.C.(Understand, Value, Enjoy, Create) 문화재교육 정립을 위한 문화재교육 목표 연구)

  • To date, cultural property education has seen rapid quantitative growth due to national and personal needs. However, qualitative growth is lacking. The objectives of cultural property education have not been established, and therefore, even its identity is not clear. The most pressing issue at present in cultural property education is to first set objectives. This study aimed to analyze the objectives of current cultural property education, identify the problems, and set new objectives to meet significant national and personal needs in terms of education. The problems with the objectives of current cultural property education are that the persons interested in the education do not understand the concept of the education objectives clearly and that the objectives do not contain much actual content of the education. Also, the objectives of the education do not take into account the dynamic competencies and interests of the learners and do not satisfy the changes of the times. To solve these problems, new cultural property education, called 'U.V.E.C.,' was offerred. U.V.E.C. education is aimed at understanding cultural properties, recognizing their value, and enjoying them, and at creating culture. The objectives of U.V.E.C. cultural property education were set such that they can be modified flexibly in a learner-centric way with clear and practical format and contents. Based on this direction, stepwise objectives were set including overall objectives, detailed objectives, and practice objectives, and objective cases of each step were proposed. Considering the generality of the education and the distinct characteristics of the cultural properties, the U.V.E.C. education objectives took into account the diversity of behavioral objectives, clearness in statements, the objectives of problem solving, the initiative of learners and openness for expression outcomes. The U.V.E.C. objectives are clear and specific so that teachers can enhance their pedagogical efficiency and learners are able to develop interesting and diversified competencies. In addition, it is expected that the U.V.E.C. objectives will significantly affect objective setting for education on cultural properties which have not been studied widely. Further systemic and specific studies on the contents and methods of the U.V.E.C. education would help to change the overall education on cultural properties and position the field as a new academic area.

  • The purpose of this study was to provide basic data for maintenance and repair of the forest road surfaces using the light drop weight test (LDWT), density test, and grain size analysis at four sites in Yeongyang-gun Mt. (2011y, 2014y, 2016y, and 2017y). In terms of the density test results, the opening density in 2011 was the highest at $2.0694g/cm^3$, and the opening density in 2017 was the lowest at $1.7443g/cm^3$. The grain size analysis showed that the proportion of large aggregates was highest at the opening in 2017, and the proportion of large aggregates decreased with the delay of opening date. From the LDWT results, $E_{vd}$ (the dynamic deformation coefficient) of the 2011y forest road was $35.7MN/m^2$, 2014y was $30.5MN/m^2$, 2016y was $28.6MN/m^2$, and 2017y was $23.5MN/m^2$. The $E_{vd}$ value for the oldest forests opened with the 2011y forest road was the highest, the average $E_{vd}$ value of the center portion was $21.45MN/m^2$, the average $E_{vd}$ value of the wheel portion of the banking part was $31.31MN/m^2$, and the average $E_{vd}$ value of the wheel portion of the cut part was $36.71MN/m^2$.

  • Comparative blood analysis was carried out to investigate the change of blood constituent in TAE-EUM-IN group and control group. RBC, WBC, hemoglobin, hematocrit, total protein, triglyceride, phospholipid, total cholesterol, LDL-cholesterol, HDL-cholesterol, BUN, creatinine, ACTH, cortisol and prostaglandin E and $F_2{\alpha}$ were measured. And the following results were obtained: 1. In the change of blood cell, the value of hematocrit showed significant difference, while that of RBC, WBC and himoglobin didn't. 2. In the change of protein, the value of total protein showed significant difference, but that of albumin didn't. 3. In the change of lipid and cholesterol in serum, the value of triglyceride, phospholipid, total cholesterol and LDL-cholesterol indicated significant difference, while that of HDL-cholesterol indicated significant difference, while that of HDL-cholesterol didn't. 4. The value of BUN in serum represented significant difference, but that of creatinine didn't. 5. The value of cortisol in plasma showed significant difference, but that of ACTH didn't. 6. The value of prostaglandin E and $F_2{\alpha}$ in plasma showed significant difference. These results suggest that investigation on hormones and blood constituents enables objectification in differentiation of four types of physical constitution.

  • The purpose of the study is to investigate how customer reward programs that are provided strategically to develop customer favors are assessed by customers, if they affect customer loyalty and what effect using membership card(how many possess and use it) takes. The findings from the study can be summarized as follows. Firstly, customer loyalty showed high when shared value and convenient value are felt for preference and referring effect and when shared value and allied value were felt for revisit. Secondly, when the number of cards in possession was a lot, high customer loyalty existed. Thirdly, when the number of cards in use was a lot, the customer loyalty was high. The customer's awareness of values, e.g. economic, shared, use, convenience and allied values, put a very meaningful positive effect on loyalty, i.e. preference, referring effect and revisit. The more the number of food service provider's' membership cards in use and in possession was, the higher customer loyalty was. This implies that continued development of business partners and quality control are critical for various benefits and shared value of the customer reward pro-grams and service upgrade.
