Vendor Managed Inventory(VMI) is a distribution channel system where the inventory at the retailer is monitored and managed by the manufacturer or vendor. By pushing the decision making responsibility further up the supply chain and centralizing the replenishment decision, the vendor can help the entire supply chain be more competitive. The purpose of this research is to explore the factors influencing the adoption of VMI by Korean manufacturers. This research proposes the IT readiness, operating cost, and information sharing as antecedents of burden for VMI, and collected the survey responses from the small-to-medium manufacturers. The statistical results indicate that only the operating cost has a significant impact on the adoption of VMI. However it has also been found that the IT readiness and information sharing have a significant effect on the operating cost. Thus indirectly influence the adoption of VMI. As a conclusion, the academic and practical implications of these findings are discussed.

Texts and icons are used to deliver the safety and health information on pesticide labels. This study surveyed the standards or guidelines regarding the presentation formats of texts and icons used in pesticides. Also, the text and icon formats being used in the 50 pesticide products in Korea were investigated in the aspects of size, font (texts only), color. From the guideline survey, it was found that while the guidelines for the text fonts and colors in pesticides were suggested, there was no detailed guidelines about the text size. For the icon presentation, it was regulated that the icon size for the pesticides should be larger than $7mm{\times}7mm$, and this size was equivalent to the size when the reading distance of 28 ㎝ was applied to other two guidelines. From the sample survey of the 50 pesticides, it was found that the small text size being used in the 50 pesticides was 1mm (3pt), and this size was considered to be very difficult to be read, particularly by old people. The minimum size of the texts for the toxicity of the pesticide, the very important safety information, was found to be 1.5 mm, which is considered to be very uncomfortable to be read. The size of icons were varied from 2 to 12 mm, and the total average size was 4.6 mm. The 149 icons from a total 187 icons (80%) were smaller than the icon presentation guideline ($7mm{\times}7mm$), and the reason for the small icon size might be the small area of the label of the pesticides. Thus, more detailed guidelines for the text size and more practical guidelines for the size of icons are required.

Information Technology represents substantial financial investment for government organization. However, it seems that the real goal of IT investment, which is to make government more efficient, effective, and responsible through IT systems, has not been seriously aware of in the government organizations. As a result, despite of large investment in IT over many years, substantial benefits accrued to the work, such as process innovation and work efficiency, have not actually occurred. In this paper, it is argued that, since IT benefits will not be realized without any effective benefits realization efforts, it is needed in IT evaluation to put more emphasis on the efforts. Therefore, it is suggested that appropriate IT evaluation can possibly work as a guideline for deriving the desired benefits through the IT investment. In this study, some of the well known approaches were reviewed about what IT evaluation and IT benefits realization efforts should be. Current evaluation method was analyzed from the perspective of benefits realization. On the basis of the analysis, this study leads to suggestions that improve the current ways of evaluating IT performance, helping government focus on realizing practical IT benefits at work.

This study aimed to determine a tourist family's perceptions of dining at a holiday destination. A key assumption of this study was that dining at an unfamiliar locale at a tourist resort is engaging in risk-taking behavior by the tourist family. In this unfamiliar setting, participation in the local food market takes on a significant role in the tourist family's sense of satisfaction and loyalty. For the purpose of this study, involvement pertains to the family's perceived relevance of the objective of this study based on inherent needs, values, and interests. For this study, 151 subjects vacationing with his/her family on Jeju Island participated. To perform research on perceived risk and involvement in terms of the decision maker's capacity, only one member of each family responded to the survey, which examined the impact on sense of satisfaction of perceived risk and involvement in the local food scene. Perceived risks were divided according to financial, performance, physical, social-psychological, and time-risk factors. Perceived risk and involvement were found to be significant predictors of the overall satisfaction of the tourist family's local food consumption. Furthermore, performance risk was determined to be significantly linked to the tourist family's dining sense of satisfaction and loyalty. These findings provide some meaningful marketing implications for Jeju Island's tourism industry. Reducing the performance risk and increasing the local food involvement may activate rural tourism and local food consumption. Theoretical and practical contributions to local food marketing are discussed.

This article describes several clinical usefullness of the telephone in psychotherapy with adolescents through case analysis by Tolchin, and discussed various management problems and some practical guidelines for therapists planning to utilize telephone psychotherapy with adolescents through literature analysis. In general, most adolescent patients in regular treatment benefit from knowing that the therapist can be reached by phone and that their call will be returned that same day. The therapist's telephone availability helps the young patient to develope a positive working alliance. Telephone psychotherapy had it's first widespread application in crisis intervention and suicide prevention. It's current uses also include enhancement of self-control in cases of self-destructive adolescents, and management of anxious, depressive, or anorexic adolescents. In addition, such widely divergent modalities of treatment as follow up of patients discharged from a psychiatric hospital, alcoholic rehabilitation programs, drug hotlines, sex counselling group therapy for visually impaired elderly, control of separation anxiety in girls, resolution of fear on the mental disorders, and helpful modality to continue psychotherapy without geographic barrier during longer periods of separation with therapist are currently available via telephone. But telephone psychotherapy is generally not suitable for more self-defensive and introverted cases, more dependent chronic callers, silent cases, test callers. the cases of telephone scatologias, the cases of intellectualized discussion, of more dependent cases calling phone in order to get attention from therapist. Telephone psychotherapy for adolescents serves as an important and useful method in the therapeutic armamentarium for this most challenging and rewarding population.

Safety and health related information for the proper use and handling of pesticides is usually printed on the surface of the pesticide products (bottle type or bag type) in the form of texts. But, the guidelines or standards for the appropriate presentation of the texts for the pesticide products are most vague or not practical. Thus, this study aimed to provide the preliminary guidelines for the text sizes based on the legibility experiments. Total twenty subjects from two age groups (young: n=10, old: n=10, five males and five females in each group) participated in the experiment. First, subjects read the text cards presented in the distance of 50cm from the eyes of the subjects. Eight different text card sets were prepared for different font type(thick gothic-type and fine gothic-type), thickness of font(plain and bold), and number of syllables (2 and 3 syllables). When subjects read the cards, the correctness of reading (correct or wrong) was recorded and the degree of discomfort (from 1: no discomfort at all to 4: can't read at all) was also evaluated for all the text sizes. Results showed that the character size should be 4 pt or larger for the young subjects to read at least one word correctly in all the text conditions. For the old subjects to read at least one word correctly, the character size should be five pt or larder. The average of the minimum character sizes for 100% correct answer is 6.1 pt for young subjects and 10.5 pt for old subjects, respectively.
