Given the extensive role of IS in everyday life and the increasing presence of women in IS users, understanding gender differences in individual technology continuance usage decisions is an important issue. Nevertheless, much of the large body of research on gender differences has just examined mean differences between women and men in terms of abilities, usage habit, and traits. Even though lots of psychology studies have shown that women, more than men, were influenced by affective factors, gender-affection-continuance use linkage has not been examined in the context of on-line shopping services. Therefore, the primary purpose of this paper is to seek to examine gender differences in terms of influence of affective factor in the context of IS continuance use. Meanwhile, IS continuance has been an important subject of study in the IT research area. To date, to explain why and how users are motivated to continue to use on-line shopping services, lots of theory-based research such as expectation-confirmation model (ECM) has been proposed. In particular, various affective factors have been proposed to explain continuance use of on-line shopping services recently. Affective factors have been regarded as essential factors for increasing relational strength and satisfaction. Several affective factors have been studied by prior IS adoption and continuance studies. Among them are enjoyment and anxiety. In IS continuance research, positive affect has been commonly and narrowly conceptualized and measured as the enjoyment which a person derives from using computers. Hence, in this study, we introduced intimacy factor, which was conceptually related to the quality of interactions and relationships in previous research. It also has been regarded as essential factors for strengthening human relationships. As a result, we have observed gender effect while examining intimacy-continuance bond. As expected based on the previous literatures, women seem to be more sensitive in affective factors. The contribution point here is that we find evidence in the context of on-line shopping services.

This study introduces a new concept for a simple, efficient and cheap sensitivity amplification of a Quartz Crystal Microbalance (QCM) based immunosensor system for the detection of tumor necrosis factor-alpha (TNF-${\alpha}$, TNF) by using an in-built magnetic system. The frequency shift due to the applied magnetic field was successfully observed on magnetic particles labeled detection antibodies, anti-human TNF-${\alpha}$, which were bound to the immunologically captured TNF-${\alpha}$ on the gold coated quartz crystals. In the present system, the magnitude of frequency shift depends on both the strength of magnetic field and the amount of target antigen applied. Significant signal amplification was observed when the additional built-in residual stress generated by the modified magnetic particles under the magnetic field applied. Used in conjunction with a sandwich type non-competitive immunoassay format, the lower detection limit was calculated to be 25 $ngmL^{-1}$ and showed good linearity up to TNF-${\alpha}$ concentrations as high as 2.0 ${\mu}gmL^{-1}$. The sensitivity, most importantly, was improved up to 4.3 times compared with the same QCM system which was used only an antigen-antibody binding without additional magnetic amplification.

최근에 넓은 공간이 요구되는 건축물에서는 칸막이 벽과 같은 비구조재의 사용이 감소됨으로써 감쇠효과가 크게 줄어들고 있으며 고강도재료의 사용으로 바닥판 구조물이 유연화, 장경간화 되어가고 있다. 대형집회공간, 쇼핑몰, 사무실 등과 같이 장경간 건축물에서는 사람의 움직임에 의하여 과도한 진동이 발생할 수 있으며 이러한 진동은 건축물의 사용성을 크게 저하시키는 원인이 되고 있다. 바닥판 진동의 주요 진동원 중의 하나가 보행하중이다. 보행하중을 받는 구조물의 진동해석에 있어서 보행하중을 적용하는 일반적인 방법은 한 절점에 보행하중을 연속적으로 가하거나 주기하중으로 이상화된 동적하중을 가하는 것이다. 그러나 이러한 방법은 보행의 이동효과를 고려할 수 없다. 본 논문에서는 실제 바닥판 구조물의 고유진동수와 감쇠비를 평가하였으며 예제 구조물의 효율적인 진동해석을 위하여 보행하중을 적용하였다.

This paper presents the HRTF based experimental approach to figure out why the human auditory perception on the interior noise source including the directional tonal components does not well match with the dominant features extracted from recorded acoustic signals in terms of psycho-acoustics. Since the general objective evaluation models for tonalness among various sound attributes are a function of width, frequency, excessive level of tonal components respectively, the directional tonal components cannot be properly evaluated without considering the effects of head-related transfer function on the binaural auditory perception. Thus, the directivity of source is additionally considered to prevent the erroneous conclusions from the same sound source in the process of source identification. The signal synthesis technique is used to solve a little difficulty in measuring all of desired acoustic signals for jury evaluation. The sound attributes of synthetic acoustics signals are analyzed to roughly predict the results of jury evaluation in advance by using sound quality factors such as loudness, sharpness, roughness, fluctuation strength and tonality. The jury evaluation is carefully conducted based on the recommended guideline suggested by N. Ottoet al. Each sound is respectively evaluated by selecting a value between -2 and 2 in intervals of 0.2 point. Through above procedure, based on the results of jury evaluation, it is confirmed that serious problems can be caused in the process of analyzing the dominant sound attributes in terms of psycho-acoustics according to the type of a microphone and a playback system.

Objective : The purpose of this study was to analyze the effect of the elastic band on ballet arabesque based on kinematics analysis. Methods : To observe the effect of the elastic band, the availability of the elastic band during movement was set as the independent variable, and the dependent variables were set by using factors from two different categories such as motor mechanics and kinematics variables. For motor mechanics variable, the muscle activity and the center of pressure(COP)'s trajectory and velocity were used. Furthermore, the physical angle was used for kinematic variables. Data samples from the experiment was used to understand the correlation between independent and dependent variables while using paired samples t-test as a data analysis tool. Results : After analyzing the result of experiment, the usage of the Elastic band on ballet arabesque movement seemed to increase the activity of the agonistic muscle, which is mainly used for movement, and to improve the stability of the supporting leg by decreasing the trajectory and velocity of the center of pressure(COP). Moreover, the elastic band increased the level of elevation of the stretching leg with reducing the angle of the hip joint that resulted into a more stable movement and furthermore providing more beauty while standing on it. Conclusion : The movement training program while the using elastic band are expected to lead to appropriate muscular development and reduce the muscle imbalance, which usually occurs to dancers, during training with unfamiliar specific movements or strengthening muscular strength for a specific movement. In addition, this work is expected to be used as a training reference to understand and learn the fundamentals of movements of ballet and other dance fields.

The purpose of this study was to evaluate the effectiveness of an intervention program using dietary consult and physical exercise conducted by public health center in Chuncheon city for obese adults. This study used a pretest-posttest design. The subjects were 58 out of 90 obese adults with body mass index (BMI) greater than $25kg/m^2$ who completed all education sessions for 8 weeks. Data on dietary habits, dietary behaviors, nutritional knowledge, anthropometric parameters and biochemical indices and daily nutrient intakes assessed by a 24-hour recall were collected before and after the intervention program., in order to evaluate program effectiveness. After the intervention, there were positive changes in exercise status and dietary habits and nutrition knowledge accuracy. Especially, the answer of 'I drink a cup of milk every day' were significantly improved (p<0.001), and the answer of 'I don't overeat', which is a dietary attitude question was significantly improved (p<0.05). Dietary intakes of most of nutrients were not significantly different between pre-test and post-test. But calcium (p<0.05), potassium (p<0.05), vitamin A (p<0.01), vitamin E (p<0.05), and folic acid (p<0.05) were significantly increased in the female group after the intervention. Weight (p<0.05), BMI (p<0.01), blood pressure (p<0.001), were significantly decreased after program, but changes of skeletal muscle mass, body fat mass were not significant. Resting heart rate (p<0.01), flexibility (p<0.001), whole body reaction (p<0.05), grip strength (p<0.01) and balance (p<0.01) showed positive changes after the intervention. Blood glucose level in serum was significantly decreased (p<0.001). These results indicated that dietary education and exercise program was effective not only for weight reduction but also for the improvement of physical fitness in obese adults.

A bicycle is one of the most popular sporting goods in view of a sport activity and a human health. Metallic materials such as steel, aluminum, etc. were mainly used to the bicycle fork in the past. Nowadays, the carbon fiber reinforced composite materials are widely used to the manufacturing of a bicycle fork to reduce the weight and to increase the efficiency. Safety is a most important design parameter of a bicycle fork even if the weight and cost reduction are important. Bicycle failure may happen at the critical spot of a bicycle fork and cause the accident. In this paper, the composite bicycle fork will be analyzed to secure the safety and detect a critical spot by using the finite element method with Tsai-Wu failure criterion. The stress data were obtained for the laminated composites with various number of plies and fiber orientation under the bending load. Thus, design concept of a bicycle fork was proposed to secure the safety of a bicycle. The finite element analysis results show that the connection area between a steer tube and a fork blade is critical spot, and 75 or more layers of 0 degree are needed to secure the safety of a bicycle fork.
