There are two uses of zero which are both important but are different. One use of zero is as a number itself. The number zero is an abstract concept measuring the size of set with no elements in it. The second use of it is as an empty place indicator in our place-value number system. It is the notation. In this paper, we study a history of zero and the mistakes from a few earlier works in connection with some arithmetical operations involving the number zero.

Purpose - This empirical analysis determines the structured causal relations between perceived value, customer satisfaction, and repurchase intention among users of traditional markets. The results of this analysis would help merchants and market operators indevisingan appropriate strategy to successfully manage traditional markets. Research design, data, methodology - The perceived value model of traditional markets includes functional value (price), functional value (quality), emotional value, and social value. In this study, the perceived value of traditional markets is considered as an independent variable, while customer satisfaction and repurchase intention are shown as the dependent variables, where customer satisfaction is also considered as the mediating variable. The study aims to ascertain the extent of influence of the perceived value of traditional markets on customer satisfaction and repurchase intention. We use regression analysis to verify the effects. The measurement items were already deemed as reliable and valid in the previous study, but for this purpose, we made some modifications. We distributed questionnaires to 300 consumers on a national scale, and finally used 241 consumer responses among these as a sample. We analyzed the data using the SPSS 21.0 statistical program. Results - We obtained the following results. First, the order of perceived value dimensions of traditional markets that positively impact customer satisfaction is functional value (price), social value, emotional value, and functional value (quality). Second, the perceived value sometimes directly affects repurchase intention; its effect is typically strong with customer satisfaction as a parameter. The order of perceived value dimensions that positively impact repurchase intention is social value, functional value (price), emotional value, and functional value (quality). Third, the perceived value significantly influences repurchase intention, with customer satisfaction as the mediating variable. Conclusions - We should recognize the importance of perceived value in retail distribution markets, such as traditional markets. Moreover, we need to develop strategies to improve the perceived value. The practical implications of the study are as follows. First, with regards to functional value (quality; price) dimensions, we should have an appropriate assortment of high quality products that are reasonably priced. In addition, customers are satisfied with the friendly service, discounts, and other benefits provided by the merchants. Second, in terms of emotional value dimension, we need to develop differentiated events that provide fun and emotional experience to the customers. Third, in the context of social values dimension, we should strive to positively influence society to enhance social image through activities such as social services and contribution to community development. On the basis of these results, we present the implications, limitations, and future directions for the research. One of the policy implications of the study is that merchants of traditional markets must actively select customers and develop customer value. However, this study is limited in the fact that the population used for data collection is not fully representative, as the survey only covered some specific areas. Moreover, future studies could also benefit with additional research using moderating variables.

Purpose: Up to 90% of pancreatic cancer patients suffer from neuropathic pain. In a palliative care setting, pain control in pancreatic cancer patient is one of the major goals. Ketamine is a N-methyl-D-aspartate (NMDA) receptor antagonist, effective in neuropathic pain. Additionally, there have been studies about the opioid sparing effect of ketamine. This study was held in the palliative care unit among pancreatic cancer patients to determine the factors related to ketamine use and the opioid sparing effect. Methods: The medical records of pancreatic cancer patients admitted to St. Mary's hospital palliative care unit between January, 2013 and December, 2014 were reviewed. Patients were divided into 2 categories according to ketamine use. Also, opioid use before and after ketamine use was compared in the ketamine group. Results: Compared to the non-ketamine use group, patients in the ketamine group required a higher dose of opioid. The total opioid dose, daily opioid dose, number of daily rescue medications, and daily average rescue dose were statistically significantly higher in the ketamine group. The opioid requirement was increased after ketamine administration. Conclusion: In this retrospective study, ketamine was frequently considered in patients with severe pain, requiring higher amount of opioid. Studies about palliative use of ketamine in a larger number of patients with diverse types of cancer pain are required in the future.

Many phychiatrists have reported that the change of serotonin concentration would cause mental disorder and affect the pathological conditions such as schizophrenia, depression and eating behabior. The end product of serotonin metabolism was excreted as 5-HIAA in urine. Serum lipids, according to the report, were concerned with obesity, said it was. This study aims to observe the changes of plasma serotonin, urinary 5-HIAA and serum lipids, making use of Fat Cell Mass rate of 27 normal persons and 42 psychosomatic patients. For this, I also observed the change of serotonin, 5-HIAA and lipids of the psychosomatic patients by the use of 3 kinds of herbs as treatment medication on the basis of physical symptoms and the results were obtained as follows; 1. Urinary 5-HIAA is correlated with the body water rate(r=0.381), while reversely correlated with the Fat Cell Mass rate(r=-0.330). 2. Compared the control group with the patients group for the serum lipids value, they showed the significant results ; $146.4{\pm}5.71$ mg/dl and $166.9{\pm}6.56$ mg/dl in the total cholestrol value over- weights, $471.2{\pm}42.99$ mg/dl in the total lipid value, and $158.1{\pm}6.50$ mg/dl and $181.1{\pm}6.30$ mg/dl in the phospholipid of the obesity, respectively. 3. With comparison of each group to other group to the others for Fat Cell Mass rate, the total cholesterol showed the significant differences when the Fat Cell Mass rate was 20% or more, HDL-cholesterol value when 30% or more, and triglyceride when 30% or more, respectively. 4. there was significant variations in the relations between Fat Cell Mass rate and body water, which body mass index was increased as the body water was decreased. 5. Fat Cell Mass rate was correlated with Cholesterol(r = 0.420), triglyceride (r = 0.443), and $\beta$-lipoprotein(r = 0.450) of serum lipids, while reversely correlated with HDL -Cholesterol(r = -0.354) and urinary 5- HIAA had the correlation coefficient of -0.330. 6. What related with body water rate urinary 5-HIAA (r = 0.381) and $\beta$-lipoprotein(r = -0.405). 7. there were significant changes in the total cholesterol value and HDL-Cholesterol Value of serum lipids after dose of Ondamtang, significant increase in the 5-HIAA value after dose of Samulansintang, and significant devrease in the Trigylceride value of serum lipids after dose of Shihosogansan. As a result, it was seen that there was direct correlations among the Fat Cell Mass, urinary 5-HIAA, and serum lipids and stress from the mental conditions was not correlated directly to Serotonin, 5-HIAA, and serum lipids. I would like to conclude, therefore, that the detailed study should be performed on the function of serotonin of hypothalamus.

This study focused on the estimation of econcmic value and the evaluation of attitudes toward plans for the establishment of a walking tour as a public service in the city of Gwacheon. A value analysis based upon 152 questionnaires returned by the residents of Gwacheon and 175 questionnaires from the users of Seoul Race Park in Gwacheon utilized a CVM(Contingent Valuation Method) approach to estimate use value, non-use value, and potential value. The results show that 69.8% of residents and 60.0% of Seoul Race Park users had an interest, 81.6% of residents and 89.7% of Seoul Race Park users agreed to the proposed plan, and 67.8% of residents and 69.7% of Seoul Race Park users expressed a willingness to pay an additional tax or admission fee. The estimated WTP for an additional resident tax per household/year is 11,721 won while it was an additional 750 won per admission for the Seoul Race Park user group. Based on these results, the estimated total economic value of all households/year and the user group over a period of 5 years is 9,997 hundred million won, which was a doubling of the 1.4 in value of total construction costs. The results of this study strongly support the establishment of a walking tour street plan as a public service commodity.

The study results regarding the ingredient differences, sensory characteristics, purchasing type, usage and improvement direction for home-made traditional doenjang and factory produced commercial doenjang are as follows. The L-value indicates that home-made traditional doenjang has a higher value in average than the factory produce done, and the a-value indicates the opposite. Home-made traditional doenjang had higher water content than commercial doenjang ; however the pH values of commercial doenjang and home-made were 5.34 and 5.32 respectively, which was very similar. Factory produced commercial doenjang showed higher protein content than the home-made traditional doenjang. Regarding the correlation between ingredients, there was a significantly negative relationship between the L-value and a-value but a significantly positive relationship between the L-value and b-value. There were no significant relationship with water content, pH and protein content. For the color and taste, which are the sensory characteristics, commercial doenjang showed higher value than the traditional doenjang, but for smell, the values were similar. Regarding grittiness, the factory produced commercial doenjang had bigger particles than the traditional doenjang. Preference was a bit higher in the traditional doenjang. Of the 380 study subjects, most were from 40 to 49 years old (65.5%), and the most family type were nuclear families which was a total of 400 people (69%). Moreover, the most residential type was apartment which was 355people (61.2%), and for the monthly income, more than 2,510,000won was 48.3%. For the educational background, college education was 304 people (52.4%), and high school education was 199 people, 34.3%. In the usage, most of the people eat doenjang more than once a week, and usually their parents make the doenjang. People used both commercial doenjang and home-made traditional doenjang >home-made only >factory produced commercial doenjang only in that order. The reasons for using the home-made traditional doenjang aredelicate taste and flavor>more nutritious> anti-cancer ingredients in that order. The reason they use the factory produced commercial doenjang is because they don't know how to make it at home. The things that needed to be improved in the home-made traditional doenjang are bad smell> entire quality> flavor> color in order, indicating that studies for reducing bad smell are required. The things that needed to be improved in the factory produced commercial doenjang are taste & flavor> entire quality>bad smell> color in that order, indicating that people are more concern about it tasting like home-made than the smell. From the above results, we can see that better functional doenjang should be developed for family health and to increase the consumption of the doenjang, which has good functional psychological activities, also more various types of foods that use doenjang and scientific studies to reduce the home-made doenjang smell should be continuously studied. Moreover, studies on how to make the factory produced commercial doenjang taste more like traditional doenjang should be performed.

The purpose of this study was to investigate the influence of consumers' shopping value(SV), ease of use(EOU), and usefulness(U) on their purchase intention(PI) in mobile shopping mall. Path hypotheses in structural equation model which was constructed for this purpose were verified. In addition, the research model was analyzed according to the groups classified by the level of purchase experience in mobile shopping mall. The survey was limited to the respondents in their 20s and 30s living in Seoul and other metropolitan areas who had purchased fashion products in mobile shopping mall. 411 useful data collected from on-line survey were analyzed by descriptive statistics, exploratory factor analysis, confirmatory factor analysis, reliability analysis, and pearson's correlation analysis using SPSS 21 and AMOS 19. The results of verifying the hypotheses were as follows: First, SV was composed of two factors which included hedonic shopping value(HSV) and utilitarian shopping value(USV). Second, the research model was verified as an acceptable model in explaining the influence of consumers' SV, EOU, and U on PI. Third, seven hypotheses among nine hypotheses were accepted in high purchasers. HSV did not have a significant influence on PI, and EOU did not affect PI significantly. Fourth, five hypotheses were accepted in light purchasers. HSV affected U significantly while USV had a significant impact on EOU and PI. EOU affected U, and U affected PI significantly. In conclusion, USV was proven to be the factor affecting PI directly as well as indirectly. Eou and U also had a significant influnce on PI in mobile fashion shopping. These results will provide mobile marketers with the differentiated strategies to make consumers lead to mobile purchase.
