Objectives: The purpose of this study was to investigate the effects of modified fasting therapy on the changes of body compositions. Methods: We analyzed the medical records of 33 patients, who carried out modified fasting therapy at Dunsan Korean Medicine Hospital of Daejeon University from January 1st, 2011 to December 30th, 2015. They went through reducing food intakes period (7 days), fasting period (14 days) and refeeding period (14 days). Body compositions (weight, body mass index, skeletal muscle mass, percent body fat, basal metabolic rate, waist-hip ratio, visceral fat area) were reviewed at each state. And then the data was analyzed. Results: The body composition values (weight, body mass index [BMI], skeletal muscle mass, percent body fat, basal metabolic rate, waist-hip ratio, visceral fat area) decreased during the fasting therapy period, as a whole. The weight, BMI, percent body fat and visceral fat area decreased during the reducing food intakes period, the fasting period and the refeeding period. The skeletal muscle mass and basal metabolic rate significantly decreased during the reducing food intakes period and the fasting period, and insignificantly increased during the refeeding period. Conclusions: Results from this investigation showed that modified fasting therapy using fermented herbal medicine have positive effects on changes of body compositions.

Injection rate shape control is one feature of a diesel fuel injection system that is strongly desired at this time. In the conventional common rail system, it is difficult to control the injection rate since the fuel pressure is constant during the injection period, resulting in a nearly rectangular rate shape. In order to look into possible injection modulations, injectors equipped with standard and geometrically modified control valves were investigated in detail by means of computer modelling and simulation. Experiments were carried out to validate the feasibility of such a shaping. The results of this study show a noteworthy dependence of the fuel rate on geometrical modifications in the piloting stage of the injector.

This study uses the FP-tree algorithm, one of the mining techniques. This study is an attempt to suggest a new recommended system using a modified FP-tree algorithm which yields an association rule based on frequent 2-itemsets extracted from the transaction database. The modified recommended system consists of a pre-processing module, a learning module, a recommendation module and an evaluation module. The study first makes an assessment of the modified recommended system with respect to the precision rate, recall rate, F-measure, success rate, and recommending time. Then, the efficiency of the system is compared against other recommended systems utilizing the sequential pattern mining. When compared with other recommended systems utilizing the sequential pattern mining, the modified recommended system exhibits 5 times more efficiency in learning, and 20% improvement in the recommending capacity. This result proves that the modified system has more validity than recommended systems utilizing the sequential pattern mining.

This research is concerned with the active vibration controller design for smart structures by a modified LQG controller. The smart structure is defined as the structure equipped with smart actuators and sensors. Various analog and digital control, techniques aimed for the piezoceramic sensors and actuators have been proposed for the active vibration control of smart structures. In this paper, the modified LQG controller is developed for the active vibration suppression of smart structures to implement the predefined decay rate on modal displacements. The proposed modified LQG controller proved its effectiveness by experiments.

Purpose: The Inaba's procedure, the treatment of osmidrosis axillae, has the advantages of low recurrent rate and easy to learn, yet it produces early postoperative discomfort and scar formation by tie - over dressing. The authors modified the Inaba's procedure by using delayed suture of the incision wound and omitting tie - over dressing. The comparative study of Inaba's procedure and its modification was performed to confirm the advantages of modified procedure. Methods: The study contains the retrospective analysis of the medical records of 296 patients with osmidrosis who were treated using the Inaba's procedure from December, 1996 to February, 2007. The study also contains the prospective analysis of 20 patients, from March, 2007 to July, 2008, who were treated by the modified Inaba's procedure with delayed suture of the incision wound and gentle pressure dressing instead of tie - over dressing. The operative results of two groups were compared and verified by Mann - Whitney U test(SPSS 12.0). Results: The incidence of complications was 14.5% in the Inaba's procedure, whereas 6.2% in the modified Inaba's procedure. Both procedures have the same basic surgical procedure in terms of the location of incision site and subdermal shaving of the sweat glands, and therefore similar good results were obtained in the aspect of postoperative axillary odor, recurrent rate and postoperative condition of axillary hair. Certainly, the modified Inaba's procedure had better outcome in each element of PSS(Patient Scar Self-Rating Scale), compared to the Inaba's procedure. In addition, the modified Inaba's procedure showed a statistical significance in dressing - related pain reduction and overall satisfaction. Conclusion: The modified Inaba's procedure had advantages of decreased early postoperative complications such as hematoma, discomfort and pain caused by tie - over dressing, and decreased scar formation. However, the drawback was delayed suture of the incision wound after 48 hours.

The dynamic material characteristics on some mild steel sheets were observed. The dynamic tests were conducted on the ESH servo-hydraulic test machine. It was observed that the mechanical properties of mild steel are highly sensitive to the value of strain rate. The well known Cowper-Symonds constitutive equation was used to generalize the strain rate sensitivity effect. Modified constitutive equations were suggested to couple the strain hardening to the strain rate sensitivity. The dynamic stress-strain relationships for the mild steel sheets used in the present study were reasonably predicted using these modified constitutive equations.

This paper examines the BER performance of the recently proposed half-symbol-rate-carrier (HSRC) offset quadrature phase-shift-keying (OQPSK) receiver for high-speed data communication. A modified demodulation technique using a bit-time period signal integration, the bit-error-rate (BER) performance of the HSRC-OQPSK signal improves more than 4dB compared to that of a demodulation technique using a symbol-time period integration. This paper also examines the BER performance of modified demodulation with various band-limited channels modeled using low-pass filters, and the three different data-rate systems are simulated and compared with the performance of the system using the conventional demodulation technique.

Yoon et $al.^1$ presented an approximate mathmatical model to describe ammonia removal from an experimental batch reactor system with gaseous headspace. The development of the model was initially based on assuming instantaneous equilibrium between ammonia in the aqueous and gas phases. In the model, a "saturation factor, $\beta$" was defined as a constant and used to check whether the equilibrium assumption was appropriate. The authors used the trends established by the estimated $\beta$ values to conclude that the equilibrium assumption was not valid. The authors presented valuable experimental results obtained using a carefully designed system and the model used to analyze the results accounted for the following effects: speciation of ammonia between $NH_3$ and $NH^+_4$ as a function of pH; temperature dependence of the reactions constants; and air flow rate. In this article, an alternative model based on the exact solution of the governing mass-balance differential equations was developed and used to describe ammonia removal without relying on the use of the saturation factor. The modified model was also extended to mathematically describe the pH dependence of the ammonia removal rate, in addition to accounting for the speciation of ammonia, temperature dependence of reactions constants, and air flow rate. The modified model was used to extend the analysis of the original experimental data presented by Yoon et $al.^1$ and the results matched the theory in an excellent manner.

Not only mechanical properties, bonding properties, electro chemical properties, etc. but also fire safety is required in patch repair materials such as polymer modified cement mortar (PCM) which are used to deteriorated reinforced concrete structure. Unfortunately, it is very difficult to choice the appropriate repair materials because there are not enough information about fire safety properties of PCM. In this study, The combustion characters of PCM were evaluated through the heat release rate test and non-combustibility test. The pyrogenicity test uses the cone calorimeter based on the oxygen consumption method. The non-combustibility test is from the temperature change inside the furnace during the test. The effect of the types of polymer and polymer content were evaluated from the series of test. The results are like followings. 1) The higher the W/C of PCM, the lower the gross calorific value and heat generation rate in the heat release rate test. The amount of heat generation of PCM is like the order of VVA, EVA, and SBR in this study. 2) Some materials such as E45-100, E50-100, E60-100, S50-50, and S50-100 were estimated as not appropriate building materials in the non combustibility test.
