There are several types of salts that can be classified into raw salt(Chunil salt), purified salts(NaCl reagent grade) and processed salts(Bamboo salt, Purple bamboo salt using in this study) in Korea. Salts has been utilized for the food as well as for the drug in the Oriental Medicine. Purple bamboo salt(PB-salt) was made by heating up to 1300℃ nine times after putting the raw salts in the bamboo. Since salt is generally known to cause the blood pressure to elevate, this study was conducted to investigate the effect of PB-salt on an adverse reaction of the blood pressure elevation. The experiment was performed with the 2 protocols ; 1. Effect of NaCl and PB-salt administration i.v. with the different the concentration(250, 500, 750, 1000mg/kg) on a mean artery blood pressure(MAP) change. 2. Effect of 500mg/kg NaCl and PB-salt administration p.o. for 6 days on the systolic blood pressure change. The results were as follows; The results were as follows; In a short minute change of blood pressure by direct method, PB-salt adminstration did not induced the hypertension unlike NaCl adminstration. In a date change of blood pressure by indirect method, systolic blood pressure was increased about 12-18% in the NaCl administration group, whereas within 6% in the PB-salt administration group from 2 days to 5 days. These results suggest that PB-salt might have some unidentified ingredient to be changed in the course of processing, making it superior to other salts.

This study aimed to provide an empirical analysis of the effect of preventive fire administration (PVFA) and prepared fire administration (PPFA) on response fire administration (RPFA) in fire service organizations in Korea. To this end, panel data was collected from 16 metropolitan councils from the period of 2008 to 2018 and statistically analyzed using PVFA, PPFA, and RPFA. The independent variables were PVFA and PPFA, while the dependent variable was RPFA. The analysis of the current situation of the specific target for firefighting (STFF), public use facilities, proof of completion of safety families for public use facilities, and special fire inspection were sub-variables of PVFA. Fire safety education (FSE) and the mobilization for fire suppression (MFS) were sub-variables of PPFA and RPFA, respectively. In the results, STFF and FSE had a significant positive influence on the MFS. This study will contribute to the basic research regarding the investigation of the effectivity of fire service organizations in Korea.

This study found that tropical cyclones (TCs) formed for fall in 2007 over the western North Pacific were distributed in high-latitudes comparing to 56-year (1951-2006) climatological mean. The frequency and latitude of TC genesis became higher than 56-year climatological mean from September onward in 2007 and all the TCs that formed to the north of 20$^{\circ}$N was also distributed after September in 2007. These characteristics of TC genesis for fall in 2007 could be confirmed through analyzing various variables, such as a large-scale atmospheric circulation, outgoing longwave radiation (OLR), vertical zonal wind shear, and sea surface temperature (SST). On the other hand, a frequency of the TC that occurred to the north of 200N showed a clear interdecadal variation and its decreasing trend was distinctive in recent years. Its intensity was also weaker that TCs that did to the south of 20$^{\circ}$N. However, a latitude of TC genesis showed an increasing trend until recent years, whose variation was consistent with trend that through a SST analysis, warm SST went north in recent years.

The present study evaluated the beneficial effect of new diabetic formula(NDF) in diabetic rats. Adult Sprague-Dawley rats weighing 250-300 g were used. Diabetes mellitus was induced by intramuscular injections of streptozotocin(STZ, 50㎎/㎏). The extracts of NDF were orally administered at low or high dose two times a day to fasted diabetic rats for 3 weeks. Adminstration of NDF alliviated a significant reduction in weight gain in rats with STZ-induced diabetes. Following acute and repeated treatment, low dose of NDF suppressed the blood glucose concentrations of fasted diabetic rats. Repeated adminstration of NDF for 21 days improved liver and kidney functions in diabetic rats, as indicated by decline of serum alanine aminotransferase(AL T), alkaline phosphatase(ALP), blood urea nitrogen(BUN), creatinine level and kidney weights. The present study showed that NDF exerted antihyperglycemic effects and alliviated liver and renal damages caused by streptozotocin-induced diabetes.

The online advertising industry's business model undertakes the change from CPM (cost-per-mille)-based to CPC(cost-per-click)-based. However, due to the problem of 'Click Fraud', CPA (cost-per-action) has been regarded as a new step. For CPA, publishers need to get information after a user clicks an advertisement. Therefore, in CPA, the key is to get Conversion Action Data (CAD). This paper introduces two existing mechanisms for getting CAD, compare their characteristics, and analyze their limitations. Then the two new mechanisms are introduced and their requirements and feasibility are analyzed. Lastly, we compare the existing two and the new two mechanisms, and point out each mechanism's business possibility, value and Application Area. This paper will help publishers choose the most appropriate mechanism on the basis of their situation.

Customers' needs change every moment. Profitability of stores can't be increased anymore with an existing standardized chain store management. Accordingly, a personalized store management tool needs through prediction of customers' preference. In this study, we propose a recommending procedure using dynamic customers' preference by analyzing the transaction database. We utilize self-organizing map algorithm and association rule mining which are applied to cluster the chain stores and explore purchase sequence of customers. We demonstrate that the proposed methodology makes an effect on recommendation of products in the market which is characterized by a fast fashion and a short product life cycle.
