Background and Purpose : The purpose of this case-control study was to show the relationship between risk factors(past medical history, BMI, WHR, smoking, drinking), warning signs(dyscinesia, sightless, dysarthria, sensory disorder, numbness, blephalospasm, facial spasm, tension) and the incidence of stroke in korean adults. Methods : 455 stroke patients were enrolled as the case group and 180 non-stroke patients as control group from Oct. 2005 to Feb. 2006. Patients were hospitalized within 2 weeks after the onset of stroke. Obesity were defined as $BMI{\geq}25kg/m2$, $WHR{\geq}0.9$ in male and $WHR{\geq}0.8$ in female. Risk factors and warning signs were obtained from personal interview. The analysis of the data was done by chi-square test. Fisher's exact test and test-sample t-test. Results : The percentage of current smokers(or current drinkers) of case group is higher significantly than that of control group. The past medical history of risk factors were found to be transient ischemic attack(p=0.0698), facial palsy(p=0.4061), hypertension(p<0.0001), hyperlipidemia(p=0.1484), DM(p<0.0001), ischemic heart disease(p=0.0093), migraine(p=0.0014) and hypochondria(p=0.2370). $WHR{\geq}0.9$ in male had a 6.696 (3.711-12.082) odds ratio, $WHR{\geq}0.8$ in female had a 1.567 (0.659-3.726) odds ratio. $BMI{\geq}25kg/m2$ had a 2.017(1.263-3.222). The dyscinesia and sensory disorder of warning signs were found to be statistical difference between case and control group. Conclusions : According to the above results, it was found that smoking, drinking, BMI, WHR, hypertension, DM, ischemic heart disease, migraine affected to the incidence of stroke.

Objective : Silent infarct is more common in healthy elderly people and seems associated with risk of future stroke. However, the prevalence and risk factors of silent infarct are unclear. We investigated the prevalence and risk factors of silent infarct. Methods : 56 first-ever cerebral infarct patients were enrolled in this study. CT images were made of all 56 patients. We divided them into two groups according to the presence of silent infarcts and comparedage, sex, education period, WHR, hypertension, diabetes mellitus, hyperlipidemia, smoking, numbness and weakness of thumb and index finger, neck stiffness, facial spasm, and blepherospasm. Result : Silent infarcts were found in 24 patients(43%). Most infarcts(48%) were located in basal ganglia. Age, sex, education period, WHR, numbness and weakness of thumb and index finger, neck stiffness, facial spasm, and blepherospasm were similar between the two groups. Diabetes mellitus, hyperlipidemia, and smoking were higher in the silent infarct group. Hypertension was higher in the non-silent infarct group. Conclusion : The prevalence of silent infarct in first-ever cerebral infarction patients was 43% and diabetes mellitus, hyperlipidemia, and smoking were higher in silent infarct patients.

The purpose of this work is to explore the role of international entrepreneurship(IE) in explaining internationalization process of Korean ventures and to structure the model of IE with the logics of effectuation. The internationalization of entrepreneurial company is regarded as the realization of entrepreneurship which find out and use opportunities across borders in this point of view, and the realization process gets more realistic and applicable to the internationalization of ventures by effectuation. So we constructed the new concepts of the generating-internationalization-outcome capability(GIOC), which is the effectual capability allowing ventures to go international despite their lack of internal resources and experiences. Its sub-capabilities of GIOC are extemporaneous coping capability, perform-resource-in-hand capability and network-use capability. The empirical analyses of the relations among the capabilities and the performances of internationalization are performed in order to prove the rationale of the model, which provides finally significant evidences of the relationships. The key contribution of this study is that it highlights the important role of IE in internationalization of ventures and shows the possible role of effectuation in explaining the realization process of IE.

The present studies were carried out for three years from 2007 until 2009 to control nematode and to increase yield of cucumber by crashed-rape seed application at polyethylene film house. Crashed-rape seed has a lot of glucosinolate. Myrosinase decompose gulcosinolate into isothiocyanate and thiocyanate when crashedrape seed go to decay at soil. Those chemical compounds act on poison to nematode at soil. When the crashedrape seed treated at soil, an amount of thiocyanate at soil was risen up. Thiocyanate of plot treated with 200 and 400 kg crashed-rape seed per 10a was 30 and 40 mg/kg, respectively. Nematode(meloidogyne spp) population at soil was 13 to 17 nematodes per dried soil 300g. Yield of cucumber increased 6 to 15 percent to be compared with control. While, Nematode(meloidogyne spp) population of control plot were 463 nematodes per dried soil 300 g. This level was much higher than 150 nematodes which can be brought about injury to plant. Even if the more an amount of crashed-rape seed application, the higher yield of cucumber and control effect of nematode. Consider economical efficiency, 200 kg of crashed-rape seed per 10a was the most effective. Therefore, we suggest applying 200 kg of crashed-rape seed per 10a to control soil nematode when culture cucumber at plastic film house.

Background and Purpose : This study was to assess characteristics in acute stroke patients according to obesity and abdominal obesity. Methods : From1 Oct. 2005 to 31 Jul. 2007, 629 patients with a stroke were included. Patients were hospitalized within 30 days after the onset of stroke at Kyungwon University Incheon Oriental Hospital, DongGuk University International Hospital and Department of Cardiovascular and Neurologic Disease (Stroke Center), or Kyung Hee University Oriental Hospital. We investigated general characteristics preferences according to general obesity and abdominal obesity. Results : 629 acute stroke patients were included in the final analysis. Male, young age, hypertension, heart disease in the family history, hypertension in the past history, care of invalids or grandchildren and Taeumin in the Sasang constitution were higher among obese patients. Male, transient ischemic attack in the past history, smoker and Soyangin in the Sasangconstitution were higher among patients with abdominal obesity. The incidence of abdominal obesity corresponded to lower education level. Conclusions : In our study, we observed the general disposition of various characteristic distributions according to obesity and abdominal obesity in acute stroke patients.

Background : The purpose of our study was to analyze scientific papers published by South Korean plastic surgeons in journals included in the Science Citation Index Expanded (SCIE), and to evaluate the publication and research activities of Korean plastic surgeon. Methods : We conducted a survey of SCIE papers in the field of plastic surgery published by South Korean authors between 2001 and 2010 using Web of Science software. We further analyzed these results according to the number of publications per year, journals, institution, and type of papers. We also compared the total number of citations to published scientific papers. We analyzed the rank of South Korea among other countries in representative journals. Results : Overall, 667 papers were published by South Korean authors between 2001 and 2010. The number of publications increased dramatically from 2003 (n=31) to 2010 (n=139). Subsequently, the ten most productive Korean medical colleges were identified. All published papers received 2,311 citations and the citation to paper ratio was 3.49. The rank of Korea among other countries in terms of the number of published papers remained in the top 10 during the recent 10 years. Conclusions : Publication output of Korean plastic surgeon over the last 10 years showed a remarkable growth in terms of quantity and quality. Currently, Korea is among the top six countries in representative plastic surgery journals. Korean plastic surgeons have played a central role in this progress, and it is anticipated that they will continue to do so in the future.

This study surveys the improvement characteristics in old-aged muscular mitochondria by bio-active materials coated fabric (BMCF). To observe the effects, the fabric (10 and 30%) was worn to old-aged rat then the oxygen consumption efficiency and copy numbers of mitochondria, and mRNA expression of apoptosis- and mitophagy-related genes were verified. By wearing the BMCF, the oxidative respiration significantly increased when using the 30% materials coated fabric. The mitochondrial DNA copy number significantly decreased and subsequently recovered in a dose-dependent manner. The respiratory control ratio to mitochondrial DNA copy number showed a dose-dependent increment. As times passed, Bax, caspase 9, PGC-$1{\alpha}$ and ${\beta}$-actin increased, and Bcl-2 decreased in a dose-dependent manner. However, the BMCF can be seen to have had no effect on Fas receptor. PINK1 expression did not change considerably and was inclined to decrease in control group, but the expression was down-regulated then subsequently increased with the use of the BMCF in a dose-dependent manner. Caspase 3 increased and subsequently decreased in a dose-dependent manner. These results suggest that the BMCF invigorates mitophagy and improves mitochondrial oxidative respiration in skeletal muscle, and in early stage of apoptosis induced by the BMCF is not related to extrinsic death-receptor mediated but mitochondria-mediated signaling pathway.

In this study we investigated the effect of medical history on the incidence of stroke in Korean population. 217 stroke patients were enrolled as a case group. 160 non-stroke patients and 146 normal and non-stroke patients were enrolled as a control and a normal group, respectively, from Jul. 2005 to Mar. 2007. Stroke patients were hospitalized within 2 weeks after the onset of stroke. Medical history was gathered by interviewing each patient. Clinical data were analyzed using SAS software (ver 9.1). Hypertension and diabetes mellitus (DM) were statistically significant in a case group when compared with control and normal groups. Other parameters, such as transient ischemic attack, hyperlipidemia, ischemic heart disease, facial palsy, migraine, and hypochondria, did not show any statistical significance. The same association pattern was observed in the ischemic stroke patients of case group. On the other hand, hemorrhagic stroke patients of case group showed a significant difference in DM when compared with other subject groups. More efficient therapeutic strategy should be considered for patients with medical history, especially hypertensin and DM, to reduce the stroke incidence in Korean population.

Mobile devices such as smart phones have brought big changes to be called as 'mobile big bang' against which we can't go. Mobile banking service and MTS(Mobile Trading System) are freely available at any time, anywhere and we are able to activate communications between financial company staffs out of the office and take care of business works even remotely by using mobile devices. Mobile devices are approaching as 'smart mobile innovation' to improve an enterprise productivity and competitiveness, but threats which engaged in unfair trading behaviors or unwholesome business works in finance companies are increasing and the customer's information can be leaked out by using the nonpublic official information and mobile devices. Therefore, we have to analyze the potential problems and take the necessary countermeasures with preemptive steps to protect the customer's information and improve the financial trading soundness and fairness. In this paper, we would like to suggest countermeasures and threats against using the financial company's mobile devices focusing on the financial investment companies by 'Capital Market and Financial Investment Business Act'.

Gyeong Po in Gangneung is highly recognized as a scenic area that is home to twelve traditional pavilions which are still in existence today. Since the modification of the Natural Park Act in 2007, there has been serious concern about the regulation of the heights of buildings surrounding Gyeong Po. In light of this, the present study aims to provide some guidelines for the regulation of building height in the modified Natural Park Act on the basis of investigations of landscape characteristics of Gyeong Po and the psychological influences of changing building heights. The analysis of the view from the pavilions located around Gyeong Po Lake indicated that the strategic landscape control points were Gyeong Po Dae and Bang Hae pavilions in terms of landscape management. These two landscape control points were considered as points from which people could view the greatest part of the landscape surrounding Gyeong Po Lake. The results of a preference analysis revealed that the views from Gyeong Po Dae to Juk Do were of relatively higher preference than the view from Bang Hae pavilion. This finding emphasized the importance of landscape management in Juk Do and its surroundings. A factor analysis resulted in three factors including attractiveness, tranquility, and orderliness. A comparison of the magnitude of influence of these three factors showed that the order of influence to preference was: attractiveness>tranquility>orderliness. These results highlight the need to introduce landmarks or unique buildings into the areas because the panoramic views of Gyeong Po Lake are relatively flat as lake views go. There should also be a variety of skylines harmonizing with the natural landscapes and landscape management for building groups, rather than individual building control, to enhance tranquility. Analysis of the psychological effects of building height suggests that, regardless of view points, preference was split at a 30 meter building height. This was indicative that viewer preference would drop when building heights are controlled to allow heights over 30 meters. The present study was not able to take varying view points and story heights into account. A more detailed study considering building types, the arrangement of buildings and the number of building stories is needed for effective landscape management in the Gyeong Po Dae area.
