  • This study examined the effects of brand attachment on internal modification behavior and usability expanding behavior of product. It has been found that the attribute alignable difference of product plays a moderating effect in internal modification behavior and usability expanding behavior. As a result of the study, the more brand attachment is high, the more behavior of product internal modification behavior and usability expanding behavior of product are high. In addition, consumers with high brand attachment showed greater internal modification behavior of the product when the difference of attribute alignability was high. Also, consumers with high brand attachment showed greater usability expanding behavior of the product when the difference of attribute non-alignability was high. Companies can improve brand attachment and retain loyal customers by increasing the difference of attribute alignability in consumer's product internal modification behavior. In terms of consumer's behavior of expanding product usage, we can strengthen brand attachment and can be used as a differentiated competitive advantage of products through the attribute nonalignable difference.

  • An 11-year-old, toy poodle dog was presented with dermatologic lesions and mammary gland tumor (MGT) evaluation. A solitary, lobulated MGT (size $2.5{\times}3.5$ cm) was affecting the 5th left mammary gland. Firm, oval plaque skin lesions were present on the left dorsal carpal area. The skin lesions were alopecic and salivary staining. The dog had historical separation anxiety and excessive licking of skin lesions were observed. Based on the clinical and histopathologic examinations, MGT was diagnosed with mammary complex adenoma and the skin lesions were diagnosed with acral lick dermatitis. Behavior modification treatment using oral clomipramine was effective.

  • Nylon 12 elastomer was slightly crosslinked in molten state by the addition of small amount of dicumyl peroxide (DCP) as a crosslink agent and triallycyanuate (TAC) as a co-agent during melt compounding at $160^{\circ}C$ in an internal mixer. The effect of the peroxide crosslinking on mechanical, dynamic mechanical and rheological properties of the nylon 12 elastomer was investigated by means of tensile testing, dynamic mechanical analysis (DMA) and small amplitude oscillating rheometer, respectively. With modification, there is an improvement in tensile modulus and Young's modulus with decease in elongation at break. DMA results for peroxide modified nylon 12 elastomers demonstrated that the glass transiaiton temperature of PTMG segment shifted to higher temperature and the storage modulus remained constant above the melting temperature of nylon 12 segments. Melt rheological studies revealed that the peroxide modified nylon 12 elastomer exhibited a more solid like behavior and stronger shear thinning behavior compared to neat nylon 12 elastomer, which was more prominent at higher TAC content in the polymer matrix. The peroxide modified nylon 12 elastomer exhibited good elastic recoverability and improved mechanical properties without sacrificing melt processibilty, and especially the service temperature range increased as compared to neat nylon 12 elastomer.

  • Shape memory alloys(SMAs) exhibit pseudoelastic behavior, characterized by the recovery of an original shape even after severe deformation, during loading and unloading within appropriate temperature regimes. The distinctive mechanical behavior is associated with stress-induced transformation of austenite to martensite during loading and reverse transformation to austenite upon unloading. To develop a material model for SMAs, it is imperative to consider the difference in moduli of active phases. For example, the Young’s modulus of the martensite is one-third to one half of that of the austenite. The model proposed herein is a modification of the one proposed recently by Ho[17]. The prediction of the behavior of SMAs during unloading before the onset of reverse transformation was improved by introducing a new internal state variable incorporating the variation of the elastic modulus.

  • A number of nursing researchers have used the concept of health locus of control over the past decade in Korea. This article reviewed 92 nursing research papers on health locus of control conducted since 1982, and examined type of subjects, design, measurement instruments, the scores of each dimension of the HLOC, and significant variables. Most of the research were correlational in design, used an 18-item 6-point score instrument and studied the relationship between HLOC, health re-lated variables, and cognitive-emotional variables, The health related variables included health behavior, health management, preventive health behavior, compliance to treatment regimen and self care behavior The cognitive-emotional variables included depression, anxiety, stress and self- esteem. Some consistent findings are beginning to emerge. The concept of internal HLOC was positively correlated with the health related variables. But few studies found any significant correlation between powerful others HLOC and health related variables. In the case of chance HLOC, few studies reported a significant relationship. Many of the articles reported significant relationships between internal HLOC and cognitive-emotional variables, but few reported a significant relationship between powerful others or chance HLOC and cognitive -emotional variables. all experimental studies but one found that only internal HLOC was significantly changed following experimental manipulation. When the different groups of subjects such as normal persons, chronic patients, acute patients were compared in terms of mean scores, it was found that the HLOC appeared to change depending on the status of the patients. Recommendations for future research include modification of the instrument to increase the reliability and validity, study about the pattern of response suggested by Wallston and Wallston(1982) and further experimental study on changing the belief of subjects to internal HLOC.

  • Utilization of fiber beam-column element has gained considerable attention in recent years due mainly to its ability to model distributed plasticity over the length of the element through a number of integration points. However, the relatively high sensitivity of the method to modeling parameters as well as material behavior models can pose a significant challenge. Residual drift is one of the seismic demands which is highly sensitive to modeling parameters and material behavior models. Permanent deformations play a prominent role in the post-earthquake evaluation of serviceability of bridges affected by a near-fault ground shaking. In this research, the influence of distributed plasticity modeling parameters using both force-based and displacement-based fiber elements in the prediction of internal forces obtained from the nonlinear static analysis is studied. Having chosen suitable type and size of elements and number of integration points, the authors take the next step by investigating the influence of material behavioral model employed for the prediction of permanent deformations in the nonlinear dynamic analysis. The result shows that the choice of element type and size, number of integration points, modification of cyclic concrete behavior model and reloading strain of concrete significantly influence the fidelity of fiber element method for the prediction of permanent deformations.

  • A multidisciplinary weight control program was conducted for obese women. The major components of the program included low calorie diet therapy, exercise, behavior modification and nutritional education and counseling. Sixteen healthy volunteers in excess of body fat, above 30%, were enrolled in the group support program. But 5 person were dropped out in the 2nd week of treatment. During the 1st week of group orientation, individual cause of obesity was assessed through a computer program including survey of dietary intake, activity, eating habits and life styles. During the 5 weeks of treatment, 4.8kg of average weight loss was accomplished using a following program ; low calorie diet(1200kcal/day with all essential nutrients), low impact aerobic exercise(50~60% of $VO_{2max}$, 1 hour/day in a group, 3~5 days/week), behavior modification of individual life styles and eating habits causing obesity and nutritional education concerning nutrition, role of exercise such as brisk walking, importance of slow eating in regular meal pattern and internal motivation for weight reduction, health risk of obesity and rapid weight loss, weight recycling and yo-yo syndrome, etc. Nutritional conseling was conducted 3 times per week with checking self-records of foods, activity, emotional state and tiredness. Before and immediately after 5 weeks of treatment, blood pressure, fasting blood glucose, cholesterol and triglyceride were measured and comparied with paired t-test. After 5 weeks of treatment, body weight, body mass index, body fat and circumferences of waist, upper arm and hip were significantly decreased. Also LDL-cholesterol was significantly decreased after obesity treatment.

  • Induction surface hardening is widely used to enhance local strength and hardness. However, most research is only to have a focus on fatigue life and fatigue behavior is not so much studied. So, in this study, Cr-Mo steel alloy(SCM440) was used to show the effect of residual stress and micro hole on the fatigue strength fur base metal and induction surface hardened specimen. In addition, the fatigue characteristic between surface hardened and fully hardened steel is somewhat different. It is caused by hardness distribution, residual stress and inclusions etc.. The modification of prediction equation of fatigue strength is proposed and predicted results show very good accuracy. A $textsc{k}$, which is calculated 1.46, is introduced to consider the effect of stationary crack with defect. A new method of modifying residual stress is proposed to examine the mean stress effect under fatigue loading.

  • Thermal stability of quasi-isotropic composite and polymeric structures is considered one of the most important criteria in predicting life span of building structures. The outdoor applications of these structures have raised some legitimate concerns about their durability including moisture resistance and thermal stability. Exposure of such quasi-isotropic composite/polymeric structures to various and severe climatic conditions such as heat flux and frigid climate would change the material behavior and thermal viability and may lead to the degradation of material properties and building durability. This paper presents an analytical model for the generalized problem. This model accommodates the non-linearity and the non-homogeneity of the internal heat generated within the structure and the changes, modification to the material constants, and the structural size. The paper also investigates the effect of the incorporation of the temperature and/or material constant sensitive internal heat generation with four encountered climatic conditions on thermal stability of infinite cylindrical quasi-isotropic composite/polymeric structures. This can eventually result in the failure of such structures. Detailed critical analyses for four case studies which consider the population of the internal heat generation, cylindrical size, material constants, and four different climatic conditions are carried out. For each case of the proposed boundary conditions, the critical thermal stability parameter is determined. The results of this paper indicate that the thermal stability parameter is critically dependent on the cylinder size, material constants/selection, the convective heat transfer coefficient, subjected heat flux and other constants accrued from the structure environment.

  • This paper presents a method for analysis of the mechanical behavior of a crankshaft in a four-cylinder internal combustion engine. The purpose of the analysis was to study the characteristics of the shaft in which the pin and arm parts were assumed to have a uniform section in order to simplify the modal analysis. The results of natural frequency transfer function and mode shape were compared with those obtained by experimental work. The results obtained from the comparison showed a good agreement with each other and consequently verified the analysis model. Furthermore, a prediction of crankshaft characteristics under the firing condition, by using the model, was performed. This study describes a new method for analyzing the dynamic behavior of crankshaft vibrations in the frequency domain based on the initial firing stages. The new method used RMS values to calculate the energy at each bearing journal and counter weight shape modification under the operating conditions.
