  • Fuzzy control algorithms are developed based on fuzzy models of systems. The control issues are posed as multiobjective optimization problems involving goals and constraints imposed on system's variables. Two basic design modes embrace on-and off-line control development. The first type of design deals with the time and state-dependent objectives and pertains to control determination based upon the current state of the system. The second design mode gives rise to explicit forms of fuzzy controller that is learned based on a given list of state-control associations. Both the fuzzy models as well as fuzzy controllers are realized as logic processors.

  • The objectives of this study were to analyze reservoir trophic state, based on Trophic State Index (TSI), spatial variation patterns of three zones (riverine, transition, and lacustrine zone), and empirical models through 20-years long-term data analysis. Trophic variables of TP and CHL-a were highest during the summer monsoon, and decreased along the main axis from the riverine to lacustrine zone. In the mean time, TN did not show the trend. Ratios of N:P and Secchi disc transparency (SD) increased from the riverine to lacustrine zone. The analysis of trophic state index (TSI) showed that mean TSI (TP) and TSI (CHL-a) were 62 and 57, respectively, and these values were highest in the transition zone during the summer. This zone should be managed well due to highest lake water pollution. The analysis of Trophic State Index Deviation (TSID) showed that algal growth was primarily limited by light penetration, and this was most pronounced in the monsoon season. The analysis of empirical models showed that the value of $R^2$, based on CHL-SD model, was 0.30 (p < 0.0001) in the transition zone and the $R^2$, based on TP-SD model, was 0.41 (p < 0.0001) in the transition zone.

  • The HDD (hard disk drive) using Load/Unload (L/UL) technology includes the benefits which are increased areal density, reduced power consumption and improved shock resistance than those of contact-start-stop (CSS). Dynamic L/UL has been widely used in portable hard disk drive and will become the key technology for developing the small form factor hard disk drive. Main design objectives of the L/UL mechanisms are no slider-disk contact or no media damage even with contact during L/UL, and a smooth and short load and unload process. In this paper, we focus on state matrix, pitch static attitude (PSA), roll static attitude (RSA), loading/unloading contour (LC/ULC), impact force and contact. Stability of slider is mainly determined by PSA and RSA. State matrix by PSA and RSA is also important indicator. Therefore we analyze state matrix of SFF HDD suspension through the LC/ULC.

  • Objectives This study is designed to examine the relationship between healthy state (完實無病) of Sasang constitution and pulse wave (脈波). Methods The subjects were 100 patients who were diagnosed with Sasang constitution and underwent pulse analyzer test. The status of urination, defecation, perspiration, and digestion was classified as good, intermediate, and poor. The power, depth, speed, and roughness of pulse waves (脈波) were analyzed. Results Patients with poor digestion had relatively powerless pulse wave (無力脈). Soeumin patients had a higher rate of poor digestion compared to other constitutions. Soyangin patients had a higher rate of poor perspiration compared to other constitutions. Soyangin with poor defecation had relatively choppy pulse wave (澁脈), and poor perspiraton had relatively slippery (滑脈). Soeumin patients with poor digestion had relatively powerless pulse wave (無力脈). Conclusions The pulse wave of poor healthy state (完實無病) is an expression of a pathological syndromes (病證) caused by lack of or damage to healthy energy (保命之主). It was concluded that the pulse analyzer can be used to evaluate healthy state (完實無病).

  • A person's job performance is the result of their efforts, influenced by their skills, personality, and perceptions of their role. Job performance is the execution of statutory obligations or functions based on the area of expertise of library personnel that are directed toward achieving the library's goals. The purpose of this study was to investigate the impact of staff motivation and self-efficacy on the job performance of library personnel in Kwara State, Nigeria. The descriptive survey approach of correlational type was used in this investigation. To cover all the library personnel at the participating public libraries in Kwara State, Nigeria, total enumeration or census survey methodologies were used. Eight objectives are used to steer this investigation. The findings demonstrated a significant correlation between staff motivation and job performance, while self-efficacy and job performance have a significant negative relationship. The authors recommend that library personnel who receive training, particularly training focused on providing them with development chances, may perceive that the organization values them as individuals, which increases their sense of self-worth and, as a result, helps them create stronger job performance.

  • 1. Objectives: We would know what kind of symptom are different according to Cold and Heat characteristics and health state. We also tried to suggest the development of Sasang Constitution diagnosis model considering of them. 2. Methods: We recruited 1,523 subjects between 10 and 80, excluding individuals who have physically or psychologically serious disease or women in pregnancy in the 21 Oriental Medical Clinics. We seperated group according to Cold and Heat characteristics and health state in CRF(Case Report Form, C-2009-002439) questionnaire and we also developed Sasang constitution diagnosis program to compare agreement according to sex and age group with Cold/Heat and health state one. 3. Results: The number of discordance items are much more than that of accordance items in group seperated according to Cold and Heat, and Health state Sasang constitution agreement rate of Cold/Heat and health state group is higher than that of total group through program. When we diagnosed Sasang constitution with different group characteristics to know the group differences, the disparity rate of the group according to Heat/Cold and Health state is lower than that of the group according to sex and age. 4. Conclusions: As Sasang constitution characteristics are different according to Cold/Heat group and Health state classification, we can upgrade Sasang constitution agreement rate with questionnaire considered of Heat/Cold and health state.

  • Introduction: Intravenous sedation is performed to ensure smooth and safe surgery. Dental anxiety is a reaction to an unknown danger. The Spielberger's state-trait anxiety inventory (STAI) can be used to simultaneously evaluate the levels of state and trait anxiety. State anxiety is defined as subjective feelings of nervousness. This study assessed the presurgical anxiety using STAI and performed intravenous sedation for patients whose level of state anxiety was > stage IV. Based on our clinical experience, it is believed that higher doses of sedatives are needed to induce the desired levels of sedation in patients with a high level of state anxiety. Objectives: This study examined whether the sedative consumption of the patient with a high anxiety level increased. Patients and Methods: Patients with state anxiety scores of ${\geq}$51 were included in Group V, and those with state anxiety scores ranging from 42 to 50 were placed in Group IV. To induce sedation, intravenous access was established, and a bolus dose of 3.0 mg midazolam was administered intravenously. Sedation was maintained by administering a continuous infusion of propofol, which was aimed at achieving an Observer's Assessment of Alertness/Sedation scale of 10-12/20. In this study, midazolam was initially administered when the body movements appeared to occur or the blood pressure increased. This was followed by the administration of higher doses of propofol if low sedation was observed. Results: There were no significant differences in the patient demographics, duration of sedation, and doses of local anaesthetic agents between Groups IV and V. The midazolam dose and mean propofol dose needed to maintain comparable levels of sedation were significantly higher in Group V than in Group IV. Conclusion: In female patients, whose level of preoperative state anxiety is more than Stage V of STAI, a large quantity of sedatives is needed for intravenous sedation.

  • Background: Classical swine fever (CSF) is a severe infectious disease of pigs that causes significant economic losses to the swine industry. Objectives: This study developed a solid-phase blocking enzyme-linked immunosorbent assay (spbELISA) method for the specific detection of antibodies against the CSF virus (CSFV) in porcine serum samples. Methods: A spbELISA method was developed based on the recombinant E2 expressed in Escherichia coli. The specificity of this established spbELISA method was evaluated using reference serum samples positive for antibodies against other common infectious diseases. The stability and sensitivity were evaluated using an accelerated thermostability test. Results: The spbELISA successfully detected the antibody levels in swine vaccinated with the C-strain of CSFV. In addition, the detection ability of spbELISA for CSFV antibodies was compared with that of other commercial ELISA kits and validated using an indirect immunofluorescence assay. The results suggested that the spbELISA provides an alternative, stable, and rapid serological detection method suitable for the large-scale screening of CSFV serum antibodies. Conclusions: The spbELISA has practical applications in assessing the vaccination status of large pig herds.

  • Objectives: This study evaluated smear layer removal by different chemical solutions used with or without ultrasonic activation after post preparation. Materials and Methods: Forty-five extracted uniradicular human mandibular premolars with single canals were treated endodontically. The cervical and middle thirds of the fillings were then removed, and the specimens were divided into 9 groups: G1, saline solution (NaCl); G2, 2.5% sodium hypochlorite (NaOCl); G3, 2% chlorhexidine (CHX); G4, 11.5% polyacrylic acid (PAA); G5, 17% ethylenediaminetetraacetic acid (EDTA). For the groups 6, 7, 8, and 9, the same solutions used in the groups 2, 3, 4, and 5 were used, respectively, but activated with ultrasonic activation. Afterwards, the roots were analyzed by a score considering the images obtained from a scanning electron microscope. Results: EDTA achieved the best performance compared with the other solutions evaluated regardless of the irrigation method (p < 0.05). Conclusions: Ultrasonic activation did not significantly influence smear layer removal.

  • Objectives: A descriptive correlational study was designed to examine the relationship of anger to psychosomatic symptoms. In addition, this study investigated the mediating effect of parental attachment in relation to anger and other variable. Methods: Data were collected from 112 subjects in grade 4 or 6, and descriptive statistics, Pearson correlation coefficient, and hierachical multiple regression were used with SPSS/PC 18.0 program to analyze the data. Results: There was a significantly positive effects between state-trait anger and psychosomatic symptoms. Father attachment negatively correlated state-trait anger and psychosomatic symptoms. Also, mother attachment negatively correlated state anger and psychosomatic symptoms. However, maternal attachment was not significantly associated with trait anger. Parental attachment had a significant mediating effect in relation to state-trait anger and psychosomatic symptoms. Conclusions: For the effective management of multi-cultural children's psychosomatic symptoms, programs including parental attachment increasing strategies should be established. These programs can increase parental attachment security which is mediator role between anger and psychosomatic symptoms.
