Objectives : Metabolic syndrome (MetS) is associated with increasing risk of cardiovascular morbidity and mortality but the risk of stroke associated with the MetS is less well established. The objective of this study was to evaluate the prevalence of MetS in stroke patients. Methods : We analyzed the data of 806 patients with acute ischemic stroke from Hanbang Stroke Registry supported by the Ministry of Science and Technology of Korea. Subjects' enrollment was done in the oriental medical hospitals of 4 universities located in the metropolitan region from April 2007 to August 2008. We analyzed all registered data and evaluated the prevalence of MetS and specific components of MetS. Results : The prevalence of MetS in stroke patients according to American Heart Association/National Heart Lung and Blood Institute (AHA/NHLBI) criteria was 59.6%. The prevalence according to the International Diabetes Federation (IDF) criteria was 41.6%. The prevalence of female patients was higher than that of male patients (71.8% vs 51% by AHA/NHLBI criteria; 61.7% vs 27.7% by IDF criteria). The prevalence of central obesity, low HDL cholesterol and hypertension was higher in female patients. There was no significant relationship between MetS and stroke subtype. Conclusions : This work gives us the basic data on the association between MetS and risk of stroke. There should be the prospective cohort studies to evaluate MetS and the risk of stroke.

The study was aimed at investigating the relationship between biomechanical properties of cervical muscles and smartphone addiction score in fifty healthy males using smartphone more than 60 minutes each day. The usage of smartphone was evaluated by smartphone addiction survey developed from Korean International Society Agency. Biomechanical properties of three major cervical muscles; splenius capitis, sternocleidomastoid and upper trapezius, were measured by Myoton, and conducted five parameters; frequency, decrement, stiffness, creep, and relaxation time. As results, all parameters had less than 2% of coefficient of variation(CV) between measurement intervals. Also, intra-class correlation coefficient(ICC) indicated a high reliability(ICC>.9, p<.01). Moreover, the smartphone addiction score was significantly different in frequency(r=.353, p<.05) and stiffness(r=.346, p<.05) on upper trapezius; in addition, in decrement(r=-.284, p<.05) and creep(r=.288, p<.05) on sternocleidomastoid. Especially, splenius capitis was closely related with the overuse of smartphone(frequency, r=-.368, p<.01; decrement, r=-.405, p<.01; stiffness, r=-.424, p<.01). In conclusion, this study implied that the overuse of smartphone is significantly related with the damage of cervical muscles, cervical pain, and headache; furthermore, Myoton can be used as an effective device to assess mechanical properties of cervical muscles.

Sales promotion is defined as the short-term incentive to encourage the purchase or sale of products and services. Retailers conduct a variety of sales promotion to encourage the purchase or sale of products and services. It is often used to induce the purchase of customers in short term and to improve the relationship with customers in the long term. Many previous studies about the effect of price discount SP on increase in sales and image improvement have conducted. But the study of non-price promotion, especially SP with 'Gifts', meanwhile, has been seldom researched. This study is to investigate the effect of the Gift SP conducted by retailers on the customer evaluation of the product and its Gifts. This study is to investigate the effect of 'Gifts', among the non-price promotion, on the customer evaluation. First of all, previous studies about the effect (-) of Sp with 'Gifts' on the customer evaluation of the product and its Gifts, and the factors that offset the negative effect of SP with 'Gifts' on quality perception are to examined. In this study, additionally, the summary of the study based on the previous studies and the research subject in the future are to be presented. Firstly, to examine the previous researches on the effect of SP which retailers conduct on the increased sales and or enhanced image, price discount SP has attracted a lot of attention as a research subject but researches on non-price sales promotion, particularly on SP with gift have seldom conducted as a research subject. Secondly, in the previous studies relevant to Price Discount SP, the long-term negative (-) effect of the target product or brand of SP has been studied. However, a few researches on the long-term negative (-) effect of SP with gift have been conducted. Thirdly, it might be brand affinity and purchase limit that buffered the negative (-) effect on the perceived quality of SP with gift which retailers had conducted. In spite of various studies conducted by many researchers, each study have discussed the consequences under certain circumstances and integrated results of research have not been in progress. It may be the research issues left to us to clearly identify the psychological mechanism of consumers until the effect of SP happens in order to theorize SP and to present a practical and useful suggestion.

To Republic of Korea in the Indo-Pacific region, the stability and prosperity of the area are directly coupled with national survival, interest. Currently, on account of strategic competition between U.S.A, and China in this area as well as supranational·non-conventional threats, the security environment is unstable, required joint/allied responses. So, lots of states inside(U.S.A., Japan, ASEAN, etc.), also, out of this Indo-Pacific area like EU-NATO, open their own strategy related in Indo-Pacific issues to be involved. R.O.K. government took its own line with publishing self strategy following this international trend, it can be shown korean government's strong intend to join in the pending security issues in this region with 'strategic clarity'. Now, R.O.K. Navy has to back up governments, policy. First, R.O.K. Navy should strengthen the relationship inside and take part in the multilateral cooperation of security. Second, to convey this deterrence message to potential threats, Navy is required to show of forces and have combined exercises. Also, as naval forces of advanced countries, Korea, Navy should be taken action in non-traditional threats, and help developing states improve their sea power. To fulfill this tasks in the wide ocean area, Navy need five inherent characteristics(mobility, flexibility, sustainability, capability of presence and projection). In the end, this paper propose the development plan following operational environment (SWOT) analysis as well.

Unlike conventional smart farms that require chemical fertilizers and large spaces, aquaponics farming, which utilizes the symbiotic relationship between aquatic organisms and crops to grow crops even in abnormal environments such as environmental pollution and climate change, is being actively researched. Different crops require different environments and nutrients for growth, so it is necessary to configure the ratio of aquatic organisms optimized for crop growth. This study proposes a method to measure the degree of growth based on area and volume using image processing techniques in an aquaponics environment. Tilapia, carp, catfish, and lettuce crops, which are aquatic organisms that produce organic matter through excrement, were tested in an aquaponics environment. Through 2D and 3D image analysis of lettuce and real-time data analysis, the growth degree was evaluated using the area and volume information of lettuce. The results of the experiment proved that it is possible to manage cultivation by utilizing the area and volume information of lettuce. It is expected that it will be possible to provide production prediction services to farmers by utilizing aquatic life and growth information. It will also be a starting point for solving problems in the changing agricultural environment.

This study analyzed the relationship between major parameters and numerical analysis results according to various excavations conducted around the urban railway, application of machine learning techniques and verified the scope of influence of the adjacent excavation on the existing urban railway box structure and the appropriateness of the safety area. This study targeted the actual negotiated adjacent excavation works and box structures around the urban railway, and the analysis was conducted on the most representative two-line box structures. The analysis confirmed that the difference in depth of urban railway, excavation depth of adjacent excavation, and depth of underground water level are important parameters, and the difference in excavation depth of adjacent excavation is the parameter that affects the behavior of underground box structures and is an important requirement for setting safety areas. In particular, the deeper the depth of the adjacent excavation work, the greater the effect on the deflection of the underground box structure, and the horizontal separation distance, one of the important requirements for determining the management grade of the existing adjacent excavation work, is relatively small.
