  • The purpose of this study was to analyze the patterns and interrelationships for meeting recommendations of physical activity, sedentary behavior, and dietary behavior in elementary school students. A cross-sectional design was used to assess 259 students ages 11 to 13 years. Physical activity (moderate to vigorous physical activity $\geqq$60min/day), sedentary behavior (viewing time for TV, computer, DVD, video, etc<3hr/day), and dietary behavior (servings of fruits and vegetables$\geqq$5times/day) were categorized into two levels: meeting recommendations or not meeting recommendations. Parents' health behaviors and home environmental variables were assessed with self-reported measures. Chi-squared tests and independent t-tests were conducted to compare anthropometric variables and the prevalence of students not meeting the recommendation for the three health behaviors. Comparison between males and females and logistic linear regression were used to determine the interrelationships of three health behaviors. 25.9% of students did not meet the physical activity recommendations. 15.4% did not meet sedentary behavior recommendations, and 41.7% did not meet dietary recommendation. Only 39.8% of students met all three recommendations, but 19.0% did not meet over two recommendations. Patterns that simultaneously did not meet two recommendations were: sedentary and dietary behavior in males (8.1%), and physical activity and dietary behavior in females (10.4%). Students who did not meet dietary recommendations were at greater risk of not meeting physical activity (OR 2.76; 95% CI 1.15 to 6.64), and sedentary behavior (OR 3.07; 95% CI 1.15 to 8.16) compared with students who did meet dietary recommendations. The findings of this study support not an independent behavior approach but a multiple behavior approach taking into account gender and interrelationships among the three behaviors.

  • Protease activity of fig (Ficus carica L.), cultivated in Korea was estimated. In particular, the proteolytic effect on myofibrilar protein was studied. A crude protease extract of fig was prepared in two ways; fig was homogenized in buffer followed by centrifugation, and the supernatant was precipitated by saturated ammonium sulfate followed by dialysis. The former method resulted in 41.15 mM/g fig protease activity, whereas the latter method resulted in 17.65 mM/g fig protease activity. The crude fig protease extract showed high specificity for casein as a substrate followed by egg white, bovine serum albumin, myofibrilar protein, collagen, and elastin. The extract had stable proteolytic activity in a pH range of 6.5~9.0 (optimal at pH 7-8) but lost activity, at pH 2-3. Proteolytic activity for myofibrilar protein was sensitive to pH. The proteolytic activity of the fig extract was steady up to $60^{\circ}C$ but declined at higher temperature. It also began to lose stability in salt concentrations >0.7 M NaCl. Fig has been used as a meat tenderizer for cooking, and these results support the tenderizing effectiveness of fig, particularly for Korean style meat marinating.

  • Plasma $dopamine-{\beta}-hydroxylase(DBH)$ activity was measured in 37 autistic disorders, 26 atypical pervasive developmental disorders and 23 controls, to elucidate the biological etiology in pervasive developmental disorders. The results are summarized as follows : 1) In the autistic group, the mean plasma DBH activity was significantly elevated compared to the atypical and control groups. The mean plasma DBH activity was also significantly elevated in pervasive developmental disorders(autistic disorder+atypical developmental disorder) compared to control group. 2) In the atypical and control groups, the DBH activity significantly increased with age, but in the autistic group, the DBH activity was not significantly correlated with age. 3) No significant correlation was found between the DBH activity and the severity of psychopathology. These findings support the hypothesis of a possible involvement of brain catecholamine dysfunction in the production of autistic symptoms, and this dysfunction might be due to the abnormal ontogenetic process of DBH activity in autistic disorders.

  • Background: The purpose of this study was to investigate the changes of trunk and lower extremity muscle activity according to the compensation of arm during bridge movement of healthy subject. Design: Cross-sectional Study. Methods: Twenty healthy subjects participated in this study. The subjects performed bridge exercise with 3 different arm positions(arm abduction 45°, 90° and cross-arms) and measured the muscle activity of the trunk and lower extrimity. During bridge exercise with 3 different arm positions, trunk (rectus abdominis, erector spinae) and lower extrimity muscle activity (gluteus medius, biceps femoris, tibialis anterior) were measured using wireless surface EMG. Results: Rectus abdominis and gluteus medius muscle were most activated during bridge exercise with arm abduction 90° and erector spinae and biceps femoris muscle were most activated during bridge exercise with arm abduction 45°. In addition, tibialis anterior muscle was most activated during bridge exercise with arm cross. However, these difference in muscle activity according to the arm position was not statistically significant. Conclusion: As a result of this study, we think that the change in arm position does not induce sufficient instability to increase the muscle activity of the trunk and lower extremity muscles. Therefore, various approaches for inducing instability of the support surface for increasing muscle activity when applying bridge movement in clinical practice should be explored.

  • Al/expanded graphite was successfully synthesized through a facile method including ultrasonic and heat treatment. In the well-designed three dimensional structure, expanded graphite(EG) works as a conductive matrix to support coated Al particles. The effects of the fabrication parameters on the microstructures and thermal conductivities of these composites were investigated. As a result, it was found that composites with graphite volume fraction of 17.4-69.4 % sintered at $600^{\circ}C$/45MPa exhibit in-plane thermal conductivities of 380-940 W/mK, over 90 % of the predictions by rule of mixture. According to the non-destructive analysis results, the synergistic enhancement was caused by the formation of efficient thermally conductive pathways due to the hybrid of the differently sized EG. The structure integrates the advantages of expanded graphite as a conductive support, preserving the electrode activity and integrity and improving the electrochemical performance.

  • Big data is an emerging technology which deals with wide range of data sets with sizes beyond the ability to work with software tools which is commonly used for processing of data. When we consider a huge network, we have to process a large amount of network information generated, which consists of both normal and abnormal activity logs in large volume of multi-dimensional data. Intrusion Detection System (IDS) is required to monitor the network and to detect the malicious nodes and activities in the network. Massive amount of data makes it difficult to detect threats and attacks. Sequential Pattern mining may be used to identify the patterns of malicious activities which have been an emerging popular trend due to the consideration of quantities, profits and time orders of item. Here we propose a sequential pattern mining algorithm with fuzzy logic feature selection and fuzzy weighted support for huge volumes of network logs to be implemented in Apache Hadoop YARN, which solves the problem of speed and time constraints. Fuzzy logic feature selection selects important features from the feature set. Fuzzy weighted supports provide weights to the inputs and avoid multiple scans. In our simulation we use the attack log from NS-2 MANET environment and compare the proposed algorithm with the state-of-the-art sequential Pattern Mining algorithm, SPADE and Support Vector Machine with Hadoop environment.

  • The German society for promotion of EIA was founded in 1987 with the aim to support the introduction of EIA in Germany. The society with its center in Hamm where there is a plenty collection of literature, studies and further scientific sources does an enormous work in EIA-consulting all over the country. This work practically is done without any governmental support, only by private activities. The EIA society is structured within 9 regional as well as 19 specialized working groups and consisits of about 1,000 members. The unification of Germany in 1989/90 also influenced the development in this field, of course. While in the former Western part of Germany the already existing environmental administrations were able to react on the EIA-law of 1990 with their long time experiences, in the Eastern part the corresponding structures must be built up newly from the beginning. Since 1990 a great number of interested people also from Eastern Germany became numbers of the EIA-Society. By them an additional pool of knowledge and activity was brought into the society. This also applies for methods and means of EIA which were developed in the East during the time ago independently.

  • This paper examined the factors affecting the implementation of information technology in Korean Global Logistics Companies. Nowadays, the spread of electronic commerce using internet demands a large changes doing business with company to company and give that company a change to recognize logistics. To support logistics activity, all kinds of companies are using the computer and are recognized that the efficient using of Cyber Logistics Information will mainly play a roll to strength the companies competition power. We gathered detailed data on our sample companies mainly from publicly available sources : Korea International Freight Forwarder Association (KIFFA), and companies' web sites. A structured questionnaire was used to collect information about: (1) the company (2) To investigate the factors of the three contexts described above on korean Global Logistics companies's electronic trade adoption and implementation. (3) Usage level of electronic logistics. Most of the approximately 70 questions enumerated in the questionnaire were open-ended, which was consistent with our primary objective of developing a conceptual framework that was informed by empirical evidence. This study suggests that top management support and influential power are main factors for the Korean Global Logistics Companies.

  • The wealth of Korean disability people's paradigm has developed by the meaning of whole rehabilitation of the small society for acception and protection. Today, that meaning has been changed to make and choose disability people's future plans by themselves. The CENTER FOR INDEPENDENT LIVING in Korea has been accepted through the American and Japanese's activity systems with no objection. Following result of the real reserching, because the CENTER FOR INDEPENDENT LIVING in Korea have no legal basement, so there are little support for these centers and no proper rules and check systems. Therefore, we have to make the legal basement of CENTER FOR INDEPENDENT LIVING and separate by each parts of system and to specialize about them. That means, each parts of system have to mark role mode for doing well, and each systems have to develop new programs and services, and to specialize for in Korea. To add, we should have more small CENTER FOR INDEPENDENT LIVING in each area, and the CENTER FOR INDEPENDENT LIVING which are already started should make network system to contact with other centers in society for giving support of proper information.
