In this paper, we evaluate the effectiveness of mechanical horseback riding exercise training for cardiopulmonary responses in 26 healthy adults (male 14, female 12) and suggest its clinical applicability. Exercise was performed using a mechanical horseback riding machine, JOBA(R) (Panasonic Electric Works, Osaka, Japan) and riding movement speed was increased from level 2 (0.73Hz), to 4 (0.9Hz), to 6 (1.03Hz), to 8 (1.2Hz), to 9 (1.3Hz) and maintained 3minutes in each level. Heart rate, blood pressure, maximum oxygen consumption (VO2max) were measured by respiratory gas analysis system (TruOne 2400, Parvo Medics, USA) and exercise tolerance test system(Q Stress, Cardiac Science, USA). To measure exercise intensity, metabolic equivalent (MET) were measured and percent of Heart rate reserve (%HRR), percent of peak heart rate (%peak HR) and calorie consumption were calculated. The results were analysed by SPSS 18.0. We found that the exercise intensity of mechanical horseback riding exercise using JOBA(R) for 15 minutes is moderate in healthy adult who received pre-training.

Purpose: This study aimed to investigate the effect of an intensive rehabilitation program on the pain, range of motion (ROM), muscle strength, function, quality of life (QoL), and depression of patients with traumatic rotator cuff injury caused by an industrial accident. Methods: Seventeen patients with traumatic rotator cuff injury caused by an industrial accident participated in this study. The 12-week treatment included 30 min of manual therapy and 30 min of exercise therapy twice a day, five times a week. The outcomes were measured for evaluating the pain, ROM, muscle strength, function, QoL, and depression before the commencement of the program and after 4, 8, and 12 weeks. Results: According to the time of applying the intensive rehabilitation program, the pain (p<0.01), ROM (p<0.01), muscle strength (p<0.01), function (p<0.01), and depression (p<0.05) significantly improved with time. However, QoL was not statistically significant. Conclusion: This study confirmed the excellent effect of an intensive rehabilitation program on the pain, ROM, muscle strength, function, and depression of patients with traumatic rotator cuff injury caused by an industrial accident. However, this study was limited by the absence of a control group. This pilot study highlights the need for more extensive research with a larger sample.

Recently, BIM(Building Information Modeling) is on the rise as a customized solution for construction environment, but construction companies rarely introduce and apply BIM in the construction site. Due to such issues, the fact that empirical data for evaluating the quantitative effect of BIM application is insufficient might be an another main reason. In the end, construction companies cannot assure investment effect of BIM and therefore don't make an investment actively. To activate BIM application, the evaluation system that quantitatively assess usability of BIM needs to be developed. This study aims to suggest a methodology that evaluates the usability quantitatively according to introduction and operation of BIM by construction companies. Accordingly, this study analyzes applicability of 4D CAD by developing an evaluation index and its model with BSC(Balanced Score Card) for 4D CAD, which have high practical use among BIM techniques, and verifies the usability as the entire evaluation index of BIM. Therefore, it is expected that the developed assessment model will be utilized as the critical decision-making information in order to introduce related techniques by identifying the usability and operational issues of 4D CAD.

The changes of electroencephalogram(EEG) in patients with dementia are most commonly studied by analyzing power or magnitude in certain traditionally defined frequency bands. However because of the absence of an identified metric which quantifies the complex amount of information, there are many limitations in using such a linear method. According to chaos theory, irregular signals of EEG can also result from low dimensional deterministic chaos. Chaotic nonlinear dynamics in the EEG can be studied by calculating the correlation dimension. The authors have analyzed EEG epochs from three patients with dementia of Alzheimer type and three matched control subjects. The multichannel correlation dimension is calculated from EEG epochs consisting of 15 channels with 16,384 data points per channel. The results showed that patients with dementia of Alzheimer type had significantly lower correlation dimension than non-demented controls on 12 channels. Topographic analysis showed that the correlation dimensions were significantly lower in patients with Alzheimer's disease on frontal, temporal, central, and occipital head regions. These results show that brains of patients with dementia of Alzheimer type have a decreased complexity of electrophysiological behavior. We conclude that the nonlinear analysis such as calculating correlation dimension can be a promising tool for detecting relative changes in the complexity of brain dynamics.

Despite the trend and severity of industrial technology outflow crime, little research has been conducted about the effect of police force on that kind of crime in Korea. Consequently, this research preliminarily empirically examined relationship between foreign affairs police forces such as policemen, budget, establishing special investigation unit and the arrest of industrial technology outflow crime due to the limit of related data. Research findings can be summarized as follows. A statistically significant positive relationship was found between foreign police budget and the arrest of crime in the country. On the contrary, foreign police force is not significantly associated with the arrest and occurrence of crime overseas. Based on the result, the effect of the police force such as hardware factors including policemen, budget on the industrial technology outflow crime seemed to be weak. Consequently, considering police alternatives from previous researches, several implications such as reinforcement of foreign police force by increasing personnel and organizational innovation, enriching training program, strengthening the domestic and foreign cooperative network between police and related bodies can be suggested. Also, the improvement of the formal statistics on the industrial technology outflow crime and strenthening public relations can be recommended.

A Compton camera, which is based on the geometrical interpretation of Compton scattering, is a very promising gamma-ray imaging device considering its several advantages over the conventional gamma-ray imaging devices: high imaging sensitivity, 3-D imaging capability from a fixed position, multi-tracing functionality, and almost no limitation in photon energy. In the present study, a Monte Carlo-based, user-friendly Compton imaging simulator was developed in the form of a graphical user interface (GUI) based on Geant4 and $MATLAB^{TM}$. The simulator was tested against the experimental result of the double-scattering Compton camera, which is under development at Hanyang University in Korea. The imaging resolution of the simulated Compton image well agreed with that of the measured image. The imaging sensitivity of the measured data was 2~3 times higher than that of the simulated data, which is due to the fact that the measured data contains the random coincidence events. The performance of a stacking-structure type Compton camera was evaluated by using the simulator. The result shows that the Compton camera shows its highest performance when it uses 4 layers of scatterer detectors.

The objective of this study proposes the new user's addiction model in 'Social Network Games' (SNGs). Research model is derived from the separation of two characteristics. First one is logical characteristics that includes 'Functional' (F), 'Keystroke' (K), and 'Goal' (G). Second one is feeling characteristics that consists a few factors such as 'Emotion' (E), 'Social' (S), and 'Affection' (A). For the pre-test, a total of 30 participants responded to survey in order to inspect the fitness of research questionnaire, roughly validity of the proposed model, and the direction of this reseach. After that for the main test, a total 300 users participated in this research. The final number of effective participants were 261 because 39 were insincere respondents and without playing SNGs who were excluded. Then we examined the measurement model by performing 'Partial Least Squares - Structural Equation Modeling' (PLS-SEM) analysis to test the research hypothesis empirically. The results of the measurement and structural model test lend support to the proposed research model by providing a good fit to the construct data. Interestingly, the model showed the significant effects of the interaction between eleven hypothesis(H1,H2,H3,H4,H5,H6,H7,H8,H9,H10, H12). Only one hypothesis decision t-value not supported that is involved the relationship between SNGs Addiction and Keystroke, H11(1.193). This research expect to contributes to an exploratory SNGs research to clarify the base of addition and will aids understanding of users' behavior associated with SNGs development.

Recently, with the increase in electrical consumption and the unbalanced power demand and supply, the power reserve rate is becoming smaller and the reliability of the power supply is deteriorating. Under this circumstance, a Battery Energy Storage System (BESS) is considered to be an essential countermeasure for demand side management. On the other hand, an economic evaluation is a critical issue for the introduction of a power system because the cost of BESS is quite high. Therefore, this paper presents economic evaluation method for utility use by considering the best mix method and successive approximation method, and an economic evaluation method for customer use by considering the peak shaving function based on the real time price. From a case study on a model power system and educational customer, it was confirmed that the proposed method is a practical tool for the economic analysis of BESS.

Purpose: To evaluate the clinical results of arthroscopic repair with Ulsan University - Mason Allen - Suture Bridge (UU MA SB) stitch for the full thickness rotator cuff tear. Materials and Methods: Fifteen patients with full thickness rotator cuff tear underwent arthroscopic repair with UU MA SB stitch between September 2010 and December 2010. Clinical and functional evaluations were made according to Korean shoulder score (KSS), American shoulder and elbow surgeon (ASES), University of California, Los Angeles (UCLA), visual anabgue scale (VAS) and the range of motion. Results: The mean KSS improved from 51.4 preoperatively to 92.0 at final follow-up (p<0.05). The mean UCLA score improved from 15.07 preoperatively to 31.93 postoperatively, the mean VAS of pain during the motion was 7.2 before treatment and 0.93 at final follow-up (p<0.001). At last follow-up, the mean range of motion was improved but they had not shown statistical significance (p>0.05). Conclusion: The arthroscopic repair with UU MA SB stitch may be an effective procedure in the full thickness rotator cuff tear for pain relief and improvement of the range of motion.

This study was conducted to evaluate the breadmaking characteristics of white bread when rice bran (RB), fermented rice bran (FRB) and rice bran oil (RBO) were added to the dough. Addition of RB to dough generally showed a decrease of the bread volume and increase of the bread weight which is related to the comparative decrease of gluten in the dough. Addition of RB also showed a decrease of lightness with yellowish color of RB and showed some rheological changes in dough. However, up to 5% RB addition, the dough showed a similar property of breadmaking with giving functional benefits compared to the control. Moreover 5% FRB addition to the dough improved the taste, flavor, and texture important to quality of bread. Substitutional use of RBO for shortening in dough result in comparative decrease of volume of dough. Addition of yellowish RBO influenced the increasing yellowness score, hardness, gumminess and brittleness, which is disadvantageous for the quality of white bread. However up to 50% RBO substitution for shortening made little rheological differences compared to the control. The 50% RBO substitution for shortening increased the score of flavor in sensory test even if there was an unfavorable quality point of white bread caused by a decreased volume and an increased hardness. From these results it could be suggested that the proper use of RB, FRB and RBO in breadmaking could improve the taste and flavor, giving beneficial function originated from rice bran to white bread.
