Essential hypertension has been considered as multifactorial disease resulted from the interaction of both environmental and genetic factors. The renin-angiotensin system (RAS) plays an important role in the regulation of blood pressure homeostasis. Recently, a homologue of angiotensin I converting enzyme, ACE2 has been focused on as a candidate gene of essential hypertension in the experiments using animal model and human being. In this study, we carried out an association study in order to clarify the relationship between the A 1075G polymorphism in the ACE2 gene and essential hypertension in Korean subjects. Because this polymorphism is located on human chromosome X, the statistical analysis for each gender was performed separately. There were no significant differences in allele distribution of the A 1075G polymorphism in the ACE2 gene between normotensives and hypertensives in the both gender groups, respectively. However, this polymorphism was significantly associated with systolic blood pressure (SBP) and diastolic blood pressure (DBP) values in only female groups (P< 0.05). Thus, these results may suggest the probable role of ACE2 gene in the inter-individual susceptibility of female group to blood pressure variability.

On the basis of the increasing interest for the selection of beverages, this study aimed to evaluate the contents of nutrients and health ${\cdot}$ functional elements in the beverages. Total 161 beverages that bear nutrition lable (NL) as nutrition table and health ${\cdot}$ functional elements information were collected and classified to 8 groups. The evaluated nutrients that are obligatory for NL in Korea were total calorie, carbohydrate, protein, fat, and sodium. Presented values showed that milk & yogurt and soy milk are the most wholesome beverages while the total caloric contents also were higher among 8 groups. Sodium contents in soy milk were higher than any other groups. The caloric contents of other beverage groups come mainly from carbohydrate presumably simple sugar. The caloric content of sports drinks is the lowest but the sodium content is variable among products showing the range of 0 - 100 mg/100 ml. Nonobligatory nutrients for NL frequently expressed are Ca, Fe, vitamin C, folate, and dietary fiber. Their content per serving size does not exceed the tolerable upper intake level, however, habitual multiple intakes of certain product require attention for the prevention of overintakes. Many health ${\cdot}$ functional elements as catechin, carnitine, polyphenol, and nucleic acids etc were listed in NL without presenting the content and their functions appear to be exaggerated compared to the known scientific evidence.

Korea professional baseball industry has grown to take the lion's share of the domestic sports industry, but still does not make break even. The purpose of this study is to examine the financial impact of adopting the Customer Relation Management (CRM) approach on the profitability of Korea professional baseball industry. We use a measuring tool called entropy used in ID3 decision tree algorithm. In the paper, we specify five the most important factors that affect spectator satisfaction based on the previous literature, perform survey analysis, calculate entropy values, and find the results. We predicted the change in revenues when we adopt CRM by checking the spectators' willingness to pay more when the conditions of each factor are improved. We find that we can reap significant fruits of the effect of CRM introduction through enhancing 'game content factor' and 'game promotion factor' among the five factors. We also find that we can increase the revenues of domestic professional baseball teams to 2.4 times or 2.1 times the current level if we manage intensively those two factors respectively. It is very surprising to see that the improvement in total revenues makes both ends meet for domestic professional baseball teams. This clearly demonstrates the effectiveness of CRM approach in improving the profitability of organizations.

The purpose of this study is to analyze the formative style and aesthetic value of contemporary subcultural style with the understanding of characteristics of subcultural style in the sociocultural context. As for the research methodology, literary survey has been performed to study the concept and the history of subcultural styles from 1940s to 1980s. In addition, demonstrative studies on aesthetic images have been carried out through the analysis of pictures and photographs in order to categorize the subcultural styles since 1990s. In this study, subcultural styles since 1990s have been illustrated through the socio-cultural grounds. which are diversity of street culture, diffusion of moss culture or bubble-up phenomenon, pursuit of anti-social ideology among intellectual heads, club Cultures in the form of kitsch and pastiche and communal thinking as collective harmony. With the socio-cultural context examined above, subcultural styles in the contemporary fashion are categorized and deduced following aesthetic values ; Drag and Club style as the tendency of surrealists or artificial hedonists, Urban military style and Cyberpunks as pursuit of Bionic being, Sports casual style based upon, the pursuit of comfort and freedom, Vintage style and Retro dressing represented by the spirit of DIY (no It Yourself), Ecology style of New conservatives, and Mysticism style as the fusion of technology and shamanism (Technoshamanism).

It is important to consider lumbar lordotic angle for setup of training program in field of sports and rehabilitaton to prevent unexpected posture deviation and back pain. The purpose of this study was to analyze the biomechanical impact of the level of lumbar lordosis angle during isokinetic exercise through dynamic analysis using a 3-dimensional musculoskeletal model. We made each models for normal lordosis, excessive lordosis, lumbar kyphosis, and hypo-lordosis according to lordotic angle and inputted experimental data as initial values to perform inverse dynamic analysis. Comparing the joint torques, the largest torque of excessive lordosis was 16.6% larger and lumbar kyphosis was 11.7% less than normal lordosis. There existed no significant difference in the compressive intervertebral forces of each lumbar joint (p>0.05), but statistically significant difference in the anterioposterior shear force (p<0.05). For system energy lumbar kyphosis required the least and most energy during flexion and extension respectively. Therefore during the rehabilitation process, more efficient training will be possible by taking into consideration not simply weight and height but biomechanical effects on the skeletal muscle system according to lumbar lordosis angles.

Purpose: The purpose of this study was to analyze the effects of using external kinesio-tape wrapping for inner arch support on the lower extremity EMG for gait in stiletto heels. Methods: Subjects for this study were two female college students who had been wearing stiletto heels almost every day of the week for more than three years. The independent variable was the presence or absence of kinesio-tape wrap for inner arch support. Dependent variables were EMG readings for the four muscle groups: the medial and lateral gastrocnemius, the tibialis anterior, and the peroneus longus. EMG readings were taken using the NORAXON (USA). The Paired t-test within the subject repeated measure design for the presence and absence of inner arch support (p<0.05) was used via SPSS 18.0. Results: With kinesio-tape wrap for inner arch support, there was a statistically significant decrease in the muscle force mean values for the peroneus longus and the medial and lateral gastrocnemius, in the maximum muscle forces of the peroneus longus and the lateral gastrocnemius. Conclusion: External kinesio-tape wrapping for inner arch support in stiletto heels could have an effect to reduce peroneus longus, and medial/lateral gastrocnemius activities that could result in decreased fatigue and discomfort.
