Purpose: Although cardiac toxicity is a key parameter of significant toxicity, in antidepressant intoxication, there are few studies on the cardiac toxicity of serotonin reuptake inhibitor and the intoxication with the new generation of antidepressants. The aim of this study is to investigate the relative cardiac toxicity of serotonin reuptake inhibitor and intoxication with the new generation of antidepressants as compared with that of tricyclic antidepressant intoxication. Methods: We retrospectively reviewed the medical records of 109 antidepressant intoxicated patients who visited the Emergency Department from January, 2005 to December, 2009 to collect and analyze the demographic and clinical data. Sixteen patients were excluded. The enrolled seventy eight patients were classified into three groups: the tricyclic antidepressant group (TCA) (n=32), the selective serotonin reuptake inhibitor subgroup (SSRI) (n=28) and the new generation antidepressant subgroup (NGA) (n=18). Results: The demographic and clinical data of the SSRI and NGA groups were not significantly different from that of the TCA group. The QRS duration of the SSRI subgroup (86.4±12.0 msec) and the NGA subgroup (91.8±11.9 msec) was not significantly different from that of the TCA group (90.0±13.5msec) (p=0.598). The QTc interval of the SSRI group (444.5±33.5msec) and the NGA group (434.9±35.9) (p=0.260) were not significantly different from that of the TCA group (431.2±44.1msec) (p=0.287). Conclusion: Intoxication with SSRI and the new generation antidepressants seemed to show significant cardiac toxicity, like what is seen in tricyclic antidepressant intoxication. Clinicians must pay attention to SSRI and new generation antidepressant intoxication.

Effects of hydrolysed Antler for prevention or therapeusis of cho1esteremia in rabbit was examined by oral administration of hydrolysed Antler to Rabbits with lanolin diet or to cholesteremia rabbits. Examination were made on the blood cholesterol value, urinary excretion of cholesterol ,cholesterol in various organs, and rabbits bred on lanolin diet were used as the control. From these experimental data, it was found that the best decholesterol action is seen in a intial added hydrolysed Antler diet.

Bacillus P-92 which fermented antler was isolated from intestinal bacteria. The biological activites, carbon clearance and growth activity of lactic acid bacteria, of fermented antler was better than those of untreated antler. The enyzmes activities, ${\beta}-glucosidase,\;{\beta}-glucuronidase$ and tryptophanase, of intestinal bacteria of mice treated with fermented antler were lower than those of mice treated with untreated antler, although those of mice treated with fermented antler or untreated antler were higher than those of control. Biological activity of the antler seems to be increased by fermentation.

Microblogging is a Web2.0 technology that is used to manage online interpersonal relationship in SNS. Microblogging service allows the users to publish online brief text updates, usually less than 140~200 characters, sometimes images too. Recently, it becomes more and more popular. There are many reasons, the major one of which is that it can be perfectly combined with mobile. Based on technology acceptance model (TAM) and according to mobile service and microblogging service, this research adds four attributes:Perceived enjoyment, Habit, Mobility, Social Influence. It studies the factors that will impact on the way in which people use rapid developing Mobile Microblogging Service. This research will compare the influence factors and intension to use with the results from other studies with SNS and Mobile Microblogging Service, and then conclude the differences that can be generated in Microblogging.

The number of those SMEs that fit into the new categories of ventures, technology innovation businesses, and management innovation businesses have soared in short time after implementing the official certification system for each. But those certified firms have shown somewhat disappointing performance. Hence, public attention and policy focus have recently shifted their gravity from simply increasing the quantity of those firms to actually enhancing the competitiveness of those firms. With these background, the main purpose of this research is to derive useful implications applied for policy-making. This research begins with the assumption that each category of ``Ventures``, ``Technology Innovation Businesses``, and ``Management Innovation Businesses`` would have difference in terms of financial performances. Thus, this research implemented ANOVA(variance analysis) test to see the difference among the three categories upon financial index related to ``Growth Potential``, ``Profitability`` and ``Productivity``.

B<sub>4</sub>C-SiC 복합체를 소결 첨가제 없이 일축가압소결법을 통해 제조하였으며 소결체의 결정상, 상대밀도, 미세구조 및 기계적 특성을 평가하였다. 제조된 B<sub>4</sub>C-SiC 복합체에서 B<sub>4</sub>C와 SiC는 균일하게 분산되어 결정립 성장을 억제하고 세밀하고 균일한 미세구조를 형성하였으며 이를 통해 B<sub>4</sub>C-SiC 복합체의 기계적 특성을 향상시킬 수 있었다. 소결온도 2,000℃, 40 MPa 압력 조건에서 소결된 B<sub>4</sub>C-SiC 복합체의 상대밀도는 99.8 % 이상이었으며, B<sub>4</sub>C 50 wt% 조성 복합체의 꺾임 강도와 비커스 경도는 각각 약 625 MPa과 30 GPa로 측정되었다. B<sub>4</sub>C-SiC composites were fabricated using hot press sintering method without sintering additives at 1,900~2,000℃ under a pressure of 40 MPa. The crystal phase, relative density, microstructure, and mechanical properties of B<sub>4</sub>C-SiC composites were evaluated. When B<sub>4</sub>C and SiC were uniformly dispersed in the composite, grain growth was inhibited, and a sintered body with a fine and uniform microstructure, with improved mechanical properties, was fabricated. The relative density of B<sub>4</sub>C-SiC composites sintered under 2,000℃ of temperature and 40 MPa of pressure was over 99.8 %, and the bending strength and Vicker's hardness at 50 wt% of B<sub>4</sub>C were 645 MPa and 30.6 GPa, respectively.

Mobile easy payment is a term for using mobile devices to facilitate financial transactions. Mobile easy payment is a quickly emerging practice, supported by the dramatic increase of mobile phone or device users around the world. The purpose of this study is to classify user’s group of the mobile easy payment service by their lifestyle based on I-VALS type and to investigate differences in usage behavior among the user groups. For empirical study, a questionnaire survey was carried out with users of mobile easy payment services using the Internet from June 7 to 10 in 2016. We conducted factor analysis for I-VALS, usage factors, satisfaction factors. We also performed cluster analysis for group classification, and analysis of variance, cross analysis to compare the different usage behavior among the user groups. In analysis results, first three cluster appeared including “ICT task-oriented group”, ICT positive and socialities oriented group”, “ICT leader-oriented group”. Second, it was found significant differences among the clusters about factor of “easy of use”, “securities”, “universality”, “satisfaction”. Third, we showed that there were significant differences in time first used the service. Based on these findings, we provide practical implications. Results of our study can be expected to provide the basis of differentiated marketing strategy of mobile easy payment services.

$CoSb_3$ with its high electrical conductivity, Seebeck coefficient and rather low thermal conductivity is quite a promising material for thermoelectric conversion applications. A potentially high figure of merit (ZT) can be achieved by a nanostructure evolution of thermoelectric materials. In this work, $CoSb_3$ nanoparticles were synthesized through a thermal decomposition method in cooperation with a hot injection technique. Nano-sized $CoSb_3$ particles were obtained through the thermal decomposition reaction between the pre-heated cobalt-oleate at $320^{\circ}C$ and the injected antimony oleate with room temperature. The results showed that the particle size was increased with increasing synthesis temperature and the crystallinity of particles was improved with temperature but the decomposition of $CoSb_3$ was observed at $320^{\circ}C$. The $CoSb_3$ particles synthesized at $300^{\circ}C$ showed a high purity and an homogeneous shape with average particle size of 26 nm.

The problem related personal information between large restaurant chains and customers is gradually spreaded. However, it is pointed out that large restaurant chains avoid legal as well as moral responsibilities advocating Personal Information Protection Law. Based on the review on these problems, it is hoped to prepare the cornerstone for studying personal information suitable for the development of tourism industry to rationalize punishment for the related personal information and damage relief by looking at the current legal system and leading cases in Korea.
