  • This paper is proposed a customized market analysis method using SVM and collaborative filtering. The proposed customized market analysis scheme is consists of DC(Data Classification) module, ICF(Improved Collaborative Filtering) module, and CMA(Customized Market Analysis) module. DC module classifies the characteristics of on-line and off-line shopping mall and traditional markets into price, quality, and quantity using SVM. ICF module calculates the similarity by adding age weight and job weight, and generates network using the similarity of purchased item each users, and makes a recommendation list of neighbor nodes. And CMA module provides the result of customized market analysis using the data classification result of DC module and the recommendation list of ICF module. As a result of comparing the proposed customized recommendation list with the existing user based recommendation list, the case of recommendation list using the existing collaborative filtering scheme, precision is 0.53, recall is 0.56, and F-measure is 0.57. But the case of proposed customized recommendation list, precision is 0.78, recall is 0.85, and F-measure is 0.81. That is, the proposed customized recommendation list shows more precision.

  • Background : Traditional Korean medicine(TKM) has gained in popularity among chronic patients in recent years. The use of TKM among patients with chronic diseases is common, with about two thirds of patients using some form of TKM in Korea. Objectives : The purpose of this study is to analyze the use of TKM and determine what factors affect to use TKM among patients with chronic diseases. The study also aims to provide information on TKM therapies and assist therapy selection among various TKM therapies for patients with chronic diseases. Methods : The design of the study was descriptive cross-sectional, and data were collected using a 21-item questionnaire. This study was conducted with subjects with confirmed diagnosis of chronic diseases, who live in Jeju Province, Korea. Results : Among the participants, past or current TKM use was 66.7%, with a statistically significant difference in gender and level of health status groups(p<0.05), but no difference in age, marital status, education, occupation, and income groups. The most common therapies of TKM used by the patients included acupuncture(51.1%), physiotherapy(16.8%), cupping(13.5%), and herbal medicine(4.8%). The main benefits from TKM perceived by the patients were chronic diseases management and health promotion. In a logistic regression analysis, significant influencing factors related to TKM use were gender, family income level, the extent of recognition of efficacy, heath status, and health security program. Conclusions : In this study the socio-demographic and health status, recognition of TKM efficacy factors associated with TKM use among patients with chronic diseases were similar to those found in the general population. The findings suggest that due to the relatively high use of TKM among patients with chronic diseases in Korea, this topic should be taken into account in the development of a holistic approach for patients with chronic diseases and an efficient chronic disease management system. Additionally proactive and consistent management of TKM is necessary in the health care system in Korea.

  • Rice whitening is performed by basically two different whitening actions known as abrasive and frictional. The former adopted in the emery stone abrasive type whiteners and the latter in the jet-air friction type. Comparative milling yields and whitening efficiencies between the whitening system consisting of jet-air friction type whiteners only and the system consisting of both abrasive- and jet-air friction-types have not yet been rigorously defined. This study was to examine the effect of combined operations of abrasive- and jet-air friction-type rice whiteners on milling yields and whitening efficiencies. The small capacity commercial units of the abrasive- and friction-type whiteners were used for the experiments. The combinations of whitening treatments were: 1) Once in the abrasive type and then two to three times in the friction type, 2) twice in the abrasive and then two to three times in the friction type and 3) three to five times in friction type. In these tests, counter pressures for the friction type whiteners were established differently as required to get about the same degree of whitening at the end of predetermined numbers of the repeated operations. The speed of emery stone and the slot angle of the screen were also the factors varied in the abrasive type whitener. Sheukwang rice variety having 13.05% M.C. was used in the tests. The dependent variables were the milled- and head-rice recoveries and electricity consumption. The results of the study are summarized as follows: 1. It was found that in the whitening systems consisting of abrasive- and friction-type whiteners slot angle of the screen, the rotational speed of emery stone roller had significant effect on the milling yields and whitening efficiency. In general, the increase of the emery stone roller speed from 690 to 950 rpm presented a positive effect on milling yield, and one-pass abrasive milling combinations had higher milling yields than two-pass abrasive milling combinations. 2. It was apparent that if the slot angle of the screen and the speed of emery stone roller are modified and set at an optimum level, the combination whitening system consisting of abrasive- and friction-type whiteners is better than the pure frictional whitening system consisting of jet-air friction type in terms of milling yields and efficiencies. 3. In the rice whitening system consisting of abrasive- and jet-air friction-type whiteners, the best whitening performance was obtained when the slot angle of the screen and the rotational speed of emery stone roller were $45^{\circ}$ and 950rpm, respectively, for the one-pass abrasive milling combinations. However, for the two-pass abrasive mi11ing combinations, the best performance was obtained with $75^{\circ}$ of slot angle and 950 rpm of the emery stone roller speed. 4. As compared with pure frictional whitening systems, the combination systems produced more milled rice by 0.8-1.0% point and more head rice by 0.5-1.5% point, and consumed less electricity by 0.15-0.20 KwH per 100kg of milled rice when the abrasive whiteners were operated in the modified conditions as described in item 3 above. Further study is recommended to find out optimum operational and design conditions of abrasive type whiterners.

  • Purpose - Goal setting is effective in any domain in which an individual or group has some control over the outcomes. It applies not only to work tasks but also to sports and health, and in various other settings. Its success depends on considering the mediators and moderators determining its efficacy and applicability. This study investigates the individual factors influencing academic goal attainability. Unlike previous studies, we focused on the effect of the relationships between individual traits (passion, tenacity, self-control) and specific motivation (vision, self-efficacy, implementation intentions) with academic goal attainability, rather than the effects of the relationship between commitment and the goal shielding mechanism with goal attainability. Research design, data, and methodology - Data collected through questionnaires were analyzed by the SPSS program. A total of 293 school students, who participated in the TOEIC program, participated in the survey. Slightly more than half were female (male: n=145 vs. female: n=148). We verified nine hypotheses through various statistical methods (reliability analysis, exploratory factor analysis, confirmatory factor analysis, structural equation model for the hypothesis test, bootstrapping test for the mediation test). Results - Data was analyzed in three phases. The first phase involved measurement analysis (i.e., item purification and factor structure confirmation), involving the scales of the three variables of individual traits, three mechanism variables, and goal attainability. The second phase involved estimating the proposed structural relationships among the key constructs (see Figure 1), using the results to test H1 to H9. The final phase involved examining the mediating effects of the three variables (vision, implementation intention, and self-efficacy). The research model shows that the independent variable passion has a significant result with both the mediators-vision and self-efficacy. Further, vision and self-efficacy significantly affect goal attainability. The second variable, self-control, shows a significant effect when mediated by implementation intentions, but the direct relationship between implementation intension and goal attainability shows an insignificant result. However, when further mediated by self-efficacy, it showed a significant effect between self-efficacy and goal attainability. Similarly, the third variable, tenacity, shows an insignificant result when mediated by vision. In contrast, the mediator self-efficacy shows a positive effect between tenacity and goal attainability. Conclusions - This study shows how these individual traits, when mediated with the appropriate motivational factors, resulted significantly in the attainability of academic goals. We may identify several theoretical and practical contributions. Theoretically, we developed a step further in the research into consumer goals and related studies. Future research could examine the effects of different learning goal types and their combinations with performance goals (e.g., learning goals first, then performance goals), different types of goal framing (approach success vs. avoid failure), the relation between goals and cognition (which, by implication, entails all of cognitive psychology), goal hierarchies, and macro goal studies with organizations of different sizes. More studies on the relationship between conscious and subconscious goals would also be valuable.

  • Purpose - The aim of this study is to develop an empirical model of the effects of traditional market service quality factors on customer value, relationship quality, and behavior. The specific objectives of the study are as follows: 1) to classify study objects into cultural tourism markets and non-cultural tourism markets as well as to verify the differences in service quality among the two markets and, 2) to present practical service marketing methods that fit with the characteristics of the traditional markets by amending the five quality evaluation items of SERVQUAL (a multiple-item scale for measuring service quality)to suit the characteristics of the traditional markets and establish the relationship among customer value, relationship quality, and behavior intention. Research design, data, and methodology - The study methods of empirical investigation are as follows. First, this study selected for a study object the Suwon Paldalmun Gate Market to represent the cultural tourism market, and general traditional markets to represent the non-cultural tourism market. This study also conducted personal interviews in order to increase the response rate and collected a total of 418 responses between March 18, 2014 and April 05, 2014. The total of 418 responses used for this study excluded 14 responses that had either misleading information or missing values. Results - This study verified the perceived differences of service quality based on traditional market specialization through an independent sample t-test. It appeared that the perceived service quality of the cultural tourism market was generally higher than that of the non-cultural tourism market. This study executed a path analysis in order to examine the effects of service quality factors on customer value, relationship quality, and behavior intention. This study also comprehensively analyzed the specialized market and non-specialized market separately. Although there were some differences among the results, the overall results were uniform. It appeared that convenience, reliability, and empathy, among the service quality factors, exerted meaningful effects on customer value. On the other hand, convenience, reliability, responsiveness, and empathy, excluding the tangibles, exerted meaningful effects on the relationship quality. In addition, it appeared that all service quality factors exerted meaningful effects on the customer value, relationship quality, and behavior intention. Therefore, the study verified that all of the hypotheses formulated in the study were generally adopted. Conclusions - The implication of this study may be classified into academic and practical implication as follows. With respect to the academic implication, it seems that this study is among the early studies to verify the differences between the cultural tourism market and the non-cultural tourism market. The practical implication of this study is that the perceived service quality, such as convenience, reliability, responsiveness, and tangibles, excluding empathy, was higher in the cultural tourism market than in the non-cultural tourism market. This means that customer satisfaction is enhanced by governmental aid such as hardware, software, and information and communications technology.

  • Colors in design elements are visual non-verbal symbols both sensual and emotional. It is the first priority in the selection of products for the consumers, and also represents differentiated strategies and coherent integration symbols for the brand. Colors in advertising is an important tool to represent the long-term image management for the brand as well as the product image and concept of the advertise. The theme of this paper is to develop creative advertisement analyzing colors from automobile video ads. Analysis results showed that video ads with small cars under 2000cc preferred pastel colors with high saturation and brightness to emphasize on individuality rather than authority. On the other hand video ads with big and luxury cars upper 2000cc preferred dark colors with lower saturation and brightness. Small car video ads focused on product appearance showing the practical value of the car, big luxury car video ads focused on the symbolic image feeling the difference between the representation of the ads. Colors used in advertisement represents the sensitivity of the consumers. In video ads the concept of the color should be set by identifying on who the globule targets are and on what item you show by identifying the corresponding colors sensitivity to suit your advertising strategy will increase the value of the brand and products.

  • Purpose The innovation capability nowadays has become increasingly prominent in the universities not only for schools but also for teachers. However, due to less attention to the knowledge utilization and management, also some objective constraints, which caused the low level of the innovation capacity for our universities teachers under the current development in China. Meanwhile, transactive memory system (TMS) and knowledge sharing are important contents in knowledge management. The combination of both systems will contribute to a much more comprehensive understanding and performance of knowledge management. The purpose of this study is to investigate the structural relationships between TMS, knowledge sharing, and innovation capability among Chinese university teachers' teams, and to propose the practical implication to integrate effectively internal knowledge of the team to improve innovation capability. Design/methodology/approach In order to exam and verify the hypothesis proposed, we developed a questionnaire with 16 survey items, and each item comes with a five-point Likert-type scale. Hyperlink of online questionnaire was shared through WeChat. It's collected 201 responses from 14 universities in China, and the responders are teaching groups' leaders. And all together 191 responses were filtered out as the valid samples. And we analyze the data set and test research hypotheses by using SPSS 22.0 and AMOS 22.0. Findings All hypotheses are supported. The results reveal that knowledge sharing plays an important role in this study as the mediating role. TMS is positively associated with the innovation capability. And the knowledge sharing plays a significant role as mediating value between them, and influences the TMS's effect on innovation capability. It's thus cleared that if our teachers could well communicate, exchange and collaborate with other teachers in the same group, the innovation capability among the teachers would be improved effectively.

  • Objectives: This study investigated the effect of electroacupuncture on swallow function in stroke patients with dysphagia. The purpose was to determine whether electroacupuncture could improve swallow function and quality of life for patients with dysphagia caused by stroke. A pilot double-blind, randomized controlled trial design was used Methods: A total of 17 stroke patients with dysphagia were recruited to this study, 8 assigned to the swallowing electroacupuncture (SE) group and 9 to the control group. Swallowing electroacupuncture was assessed for 5 Hz electrical or sham stimulation for 20 min duration 3 times a week. Outcome measurements were DOSS, 14-item questionnaire from the SWAL-QOL, NIHSS and MBI. Assessment was carried out for baseline, 2 weeks and 4 weeks Results: In the 2 weeks follow up data, the study group showed significant difference in DOSS and SWAL-QOL compared with the baseline. The study group also showed significant difference in DOSS and SWAL-QOL compared with the control group. Similarly in the 4 weeks follow up data, the study group showed improvement tendency in DOSS and SWAL-QOL compared with baseline and also with the control. The NIHSS and MBI scores returned no significant differences. The swallowing electroacupuncture was well tolerated in all cases with no serious adverse effects. Conclusions: The findings from the pilot study indicated that electroacupuncture has significant effects on improvement in swallowing function and quality of life. With both inpatients and outpatients, further larger and longer-term follow-up study is needed to confirm this suggestion.

  • Purpose: The aim of this research was to explore nurses' knowledge of and attitudes toward pediatric palliative care (PPC) in Korea. Methods: A descriptive cross-sectional design was used. A total of 196 participants were recruited from the ELNEC-PPC course held in Seoul, Korea. All participants completed a 20-item survey questionnaire which assessed knowledge of and attitudes toward PPC using a 7-point Likert scale. Results: Nurses' knowledge of PPC correlated with their educational level and work experience in the pediatric unit and hospice care unit. The work experience in the pediatric unit, career length in PPC and completion of palliative education course made differences in the attitudes toward PPC. Married nurses scored significantly higher on the parental rights in determining palliative care service for their child, and nurses with master's degree or higher showed a higher level of understanding of and attitudes toward the differences between PPC and adult palliative care. Conclusion: The factors influencing nurses' knowledge of and attitudes toward PPC need be considered to develop a pediatric palliative training program.

  • Complementary and alternative medicine (CAM) has gained in popularity among cancer patients in recent years. The use of CAM in cancer patients is common with about one third of patients using some form of CAM in Western countries. The purpose of this study was to analyze the use of CAM and determine what factors affect to use CAM among cancer patients to provide CAM therapy information and assist therapy selection among various CAM therapies to cancer patients. The design of the study was descriptive cross-sectional, and data were collected using a 16-item questionnaire. This study was conducted in subjects with confirmed diagnosis of stomach, colon, liver, or pancreas cancer, in both out-patients clinics and inpatients setting in a tertiary hospital in Seoul Korea. As a result, among the participants, past or current CAM use was reported by 75%, which shows a statistically significant difference in income groups(P<0.05), but no difference in age and religion groups. The most common therapies use by cancer patients included traditional Korean medicine (32.1%), folk remedies (26.6%), exercise (14%), dietary supplements (11.6%), physical therapy (9.9%), diet therapy (5%), and meditation (4%). 77.8% of patients show satisfaction and 64.4% shows perceived effectiveness of CAM. Male patients with higher income, and previous treatment were more likely to use CAM. The main benefits from CAM reported by cancer patients were psychological improvement and symptom improvement. Of the cancer patients used CAM, 30.9% were dissatisfied, 25.8% did not have benefits from the use, and 7.6% experience side effects. Cancer patients who prefer CAM (more than 3 kinds) used it to cure cancer, on the contrary, the one who do not prefer CAM used to improve symptoms and psychological stability. The main sources of information about CAM were family and friends(54.4%), and media(24.5%), doctor and nurse(18.3%), and religion group(2.6%). Findings suggest that due to the relatively high use of CAM among cancer patients in Korea, this topic should be taken into account in the development of a holistic approach to cancer patients and efficient cancer patients management system and proactive and consistent management of CAM is necessary in the health care system in Korea.
