International financial crises of the mid-l990s are widely perceived as the trigger that prompted recognition of the need for a new data quality management by the OECD, IMF, Eurostat and individual statistical agency. The official statistics improvements schedule in Korea was launched in 1996 as part of a broader internationally-agreed-upon initiative to strengthen transparency and promote good governance practices. These new initiatives are based on the Total Quality Management(TQM) movement and other management frameworks broadening the concept of quality beyond the traditional statistician's concepts of data quality. This paper aims to evaluate the statistics quality of Land Price Index. Evauation Method is the National Statistical Office's Data Quality Management System which focus on accuracy, timeliness, relevance, accessibility, comparability, serviceability, efficiency.

Purpose - The logistics industry is often featured by its location relevance and industrial concentration. Industrial concentration is conducive to the effective transmission of information by reducing transaction costs and improving transaction efficiency, thus promoting the development of trade. The main purpose of this paper is to measure the spatial total factor productivity and location quotient of the logistics industry in Korea, and to study the impact of the logistics industry efficiency and agglomeration effect on import and export trade in Korea. Design/methodology - First, used the spatial stochastic frontier method to measure the spatial total factor productivity of the logistics industry in Korea, this serves as the efficiency index of the logistics industry in various regions of Korea. Second, calculated the location quotient (LQ) of the logistics industry to measure the industry's concentration degree. Third, employed a spatial econometric model to analyze the impacts of factors such as the efficiency and concentration levels of the logistics industry on import and export trade in Korea. Findings - This study's main findings can be summarized as follows: this study found that the overall efficiency of the logistics industry in Korea needs to be improved, even though it showed an upward trend in all regions of the country; Moreover, the agglomeration level of Korea's logistics industry needs to be improved; Finally, the positive spatial correlation and industrial agglomeration effect of Korea's logistics industry had a positive impact on the country's import and export trade. Originality/value - This study is innovative in terms of research perspective and methods. Most of the previous studies have measured the development level of the logistics industry using the logistics performance index (LPI), Fewer studies have assessed through the spatial total factor productivity and location quotient of the logistics industry in Korea to measure the efficiency index of the logistics industry in various regions of Korea and concentration degree, as well as there was almost no study on the impact of logistics industry efficiency and agglomeration effect on import and export trade in Korea. This study addresses this limitation by analyzing the impacts of the efficiency and agglomeration effect of the logistics industry on import and export trade in Korea.

Objectives: The purpose of this study is to analyze the causes of short stature through a clinical review of factors related to childhood height growth. So we can find the way to meet the needs of the heightism which is widely spread among modern people. Methods: Among 160 patients who came to Andong B oriental clinic for the purpose of growth therapy, 112 children whose height was smaller than other normal children were analyzed. When the children first came to the clinic, we checked their height and weight. The parents' height was recorded through a questionnaire. The relationship between obesity index and height growth was examined through growth plate test and Inbody test. We want to identify the genetic factors related to parental factors based on the data of the parent height. Results: For short stature children, weight was often normal or low. When we examined the relationship between parental genetic factors and child growth, we found that they were more influenced by father's height rather than mother's. We investigated the correlation between skeletal maturity and the five viscera. There was no apparent correlation between skeletal maturity and the five viscera but we found that there was some degree of relevance. Conclusions: For short stature children, the weight was often normal or low and parental genetic factors were more influenced by father than by mother. In the case of bone maturity it did not show a direct correlation between the five viscera.

Background: The combined use of biomaterials for regeneration may have great biological relevance. This study aimed to compare the regenerative potential of biphasic calcium phosphate (BCP) alone and with growth factor enamel matrix derivatives (EMDs) for the regeneration of intrabony defects at 1 year. Methods: This randomized controlled trial included 40 sites in 29 patients with stage II/III periodontitis and 2/3 wall intrabony defects that were treated with BCP alone (control group) or a combination of BCP and EMD (test group). BCP alloplastic bone grafts provide better bio-absorbability and accelerate bone formation. EMDs are commercially available amelogenins. Mean values and standard deviations were calculated for the following parameters: plaque index (PI), papillary bleeding index (PBI), vertical probing pocket depth (V-PPD), vertical clinical attachment level (V-CAL), and radiographic defect depth (RDD). Student paired and unpaired t-tests were used to compare the data from baseline to 12 months for each group and between the groups, respectively. The results were considered statistically significant at p<0.05. Results: At 12 months, the PI and PBI scores of the control and test groups were not significantly different (p>0.05). The mean V-PPD difference, V-CAL gain, and RDD difference were statistically significant in both groups at 12 months (p<0.001 for all parameters). Intergroup comparisons showed that the mean V-PPD reduction (2.13±1.35 mm), V-CAL gain (2.53±1.2 mm), and RDD fill (1.33±1.0 mm) were statistically significant between the groups at 12 months (p<0.001 for all parameters). Conclusion: BCP and EMDs combination is a promising modality for the regeneration of intrabony defects.

This study aimed to investigate the relevance of cardiovascular disease risk factors AI and AIP, divided into three groups, among 300 individuals who underwent health checkups at the hospital. Various variables such as Age, Sex, BMI, WC, TC, TG, HDL-C, LDL-C, FBS, HbA1C, SBP, DBP, HR, AI (TC/HDL-C), and AIP (log(TG/HDL-C)) were analyzed using statistical methods including frequency analysis, cross-tabulation, one-way ANOVA, Pearson's correlation analysis, and multiple linear regression analysis. The cross-analysis based on cardiovascular disease risk criteria revealed that men and individuals in their 50s had higher cardiovascular disease risk based on AI and AIP. Significant differences were observed in TG, TC, HDL-C, LDL-C, SBP, DBP, AI (TC/HDL-C), and AIP (log(TG/HDL-C)) according to AI criteria. For the AIP criteria, TG, TC, HDL-C, FBS, HbA1C, HR, AI (TC/HDL-C), and AIP (log(TG/HDL-C)) were identified as cardiovascular disease risk factors. FBS and HbA1c showed the highest positive correlation In the correlation analysis, followed by TC and LDL-C. The lowest positive correlation was observed between LDL-C and DBP. In terms of negative correlation, HDL-C and AI had the highest negative correlation, while LDL-C and TG showed the lowest negative correlation. Multiple regression analysis indicated that the AI and AIP risk criteria had explanatory powers of 73.6% and 72.5%, respectively. HDL-C had the greatest negative effect on the AI risk criterion, while TG had the most significant influence on the AIP risk criterion. In conclusion, while other serological variables are important, managing HDL-C and TG levels may help reduce the risk of cardiovascular disease.

In this study, in an attempt to elucidate the relevance and the association between AUDIT level and health related indices such as obesity-related indices (BMI, waist circumference, body fat percentage), serum liver-enzyme levels (AST, ALT, GGT, total bilirubin) and serum lipid levels (TC, TG, HDL-C, LDL-C), data about including results of health checkup examination and questionnaire from 558 male examinees of 30-79 years old, who received a comprehensive health examination in the health promotion center of a university hospital during the period of January 1 to December 31, 2012, was analysed. As a results, the distribution of AUDIT rating of subjects was Zone I 58.2%, Zone II 25.3%, Zone III 7.0%, and Zone IV 9.5%. And AUDIT levels have significant relevance with age, smoking, body fat, GGT and TG. Especially, for the waist circumference, GGT and TG, the odds ratio indicating abnormality significantly increased in the higher AUDIT groups (Zone II~Zone IV) than a low-grade group (Zone I). This suggests that drinking problem with a high AUDIT level has a significant relevance with an abnormal increase of indices for obesity, serum liver-enzyme levels, serum lipid levels.

There is a growing tendency to outsource sensitive or important data in cloud computing recently. However, it is very important to protect the privacy of outsourced data. So far, a variety of secure and efficient multi-keyword search schemes have been proposed in cloud computing environment composed of a single data owner and multiple data users. Zhang et. al recently proposed a search protocol based on multi-keyword in cloud computing composed of multiple data owners and data users but their protocol has two problems. One is that the cloud server can illegally infer the relevance between data files by going through the keyword index and user's trapdoor, and the other is that the response for the user's request is delayed because the cloud server has to execute complicated operations as many times as the size of the keyword index. In this paper, we propose an improved multi-keyword based search protocol which protects the privacy of outsourced data under the assumption that the cloud server is completely unreliable. And our experiments show that the proposed protocol is more secure in terms of relevance inference between the data files and has higher efficiency in terms of processing time than Zhang's one.

The KPI of the four perspectives in BSC need to modify because of the change of management environment. In particular, the KPI of the financial perspective needs to modify necessarily. The KPI of financial perspective has been consisted of short-term measures: net profit current year, operating profit, ROE, ROIC, and EVA. But this financial indicators cannot afford to represent essential corporate sustainability management in the change of management environment. So this study suggests CSV(Creating Shared Value) as an additional KPI of financial perspective. And this study investigates whether CSV represents business performance as the additional KPI in BSC adoption firms. To verify a hypothesis, the sample includes listed firms announcing CSR index publicly between 2005 and 2010. The results of this study are summarized as follows. The high CSV firms is higher on the value relevance of firm in comparison with low CSV firms. Moreover, The firm value of BSC adoption firms is lower than otherwise, but it is insignificant. Limitation of Our study is that we have no choice but to use dummy variable. Because it is a material question as CSV measurement. Nevertheless, contribution of our study is to suggest new KPI of BSC perspective to meet management environment.

The purpose of this study was to investigate the effect of Saengmaeg-san intake on blood lipids and arteriosclerosis index in male tennis players. Seventeen male tennis players enrolled in university were assigned to a Saengmaeg-san intake group (n=9) and a placebo control group (n=8) according to whether they took Saengmaeg-san during 4-week high-intensity tennis training. Tennis training was conducted 5 times a week for 4 weeks, and the exercise intensity was performed at 70-90% of the spare heart rate. The intake of Saengmaeg-san was 110ml at a time before breakfast, before, during, during, and after exercise, and after dinner, a total of 7 times, 770ml per day. For all data, mean and standard deviation were used. Two-way repeated measures ANOVA was used to examine the effect of time and treatment, and Pearson's Correlation was used to examine the relevance of differences in blood lipid responses after treatment. As a result of this study, the Saengmaeg-san intake group significantly improved blood lipids (triglyceride, total cholesterol, high-density lipoprotein cholesterol, low-density lipoprotein cholesterol) and arteriosclerosis index, and there was a significant correlation appeared between ∆TG, ∆LDL-C, and ∆TC. As a result, the intake of Saengmaeg-san during high-intensity training of male college student tennis players can have a positive effect on blood lipids and arteriosclerosis index, suggesting that it can be an effective sports drink as an exercise supplement.
