Effective interventions to reduce work-related exposures are available for many types of work-related diseases or injuries. However, knowledge of the impact of these interventions on injury or disease outcomes is scarce due to practical and methodological reasons. Study designs are considered for the evaluation of occupational health interventions on occupational disease or injury. Latency and frequency of occurrence of the health outcomes are two important features when designing an evaluation study with occupational disease or occupational injury as an outcome measure. Controlled evaluation studies-giving strong indications for an intervention effect-seem more suitable for more frequently occurring injuries or diseases. Uncontrolled evaluation time or case series studies are an option for evaluating less frequently occurring injuries or diseases. Interrupted time series offer alternatives to experimental randomized controlled trials to give an insight into the effectiveness of preventive actions in the work setting to decision and policy makers.

The axis of rotation in biomechanics is a major tool to investigate joint function; therefore, many methods to estimate the axis of rotation have been developed. However, there exist several problems to describe, estimate, and test the axis statistically. The axis is directional data(axial data) and it should not be analyzed with traditional statistics. A proper comparative method should be considered to compare axis estimating methods for the same given data ANOVA (analysis of variance) is a frequently used statistical method to compare treatment means in experimental designs. In case of the axial data response assumed to come from Watson distribution, there are a few ANOVA method options. This study constructed ANOVA models for within-subjects designs of axial data. Two models (one within-subjects factor and two within-subjects factors crossed design) were considered. The empirical data used in this study were instantaneous axes of rotation of flexion/extension at the knee joint and the flexion/extension and pronation/supination at the elbow joint. The results of this study can be further applied to the various analysis of experimental designs.

Pets (such as dogs) are considered as important as family members, this perspective is due to an aging population and the decreased size of the traditional nuclear family. The pet industry has been growing every year; subsequently, is useful to develop practical patterns and designs appropriate for the body structure and movement of pet dogs. However, studies to develop a new form of pet dog's wear patterns and designs are limited. This study develops a basic pattern that is easily used based on a pet dog's size, designs popular clothing items for pet dogs, and helps in the manufactures of pet dog's wear. The results are as follow: 1) Analyzed categories and popular items of pet dog's wear from the research of the prior studies and on-line pet dog shopping malls; three categories (everyday wear, street wear, and special wear) and six items (T-shirt, one-piece, coat, jumper, and dress, tuxedo). 2) Developed the basic bodice pattern and sleeve pattern after test-wearing and revising the experimental patterns referenced from prior studies. 3) Developed patterns and designs for six popular items based on situation and gender: one-piece (everyday wear), coat (street wear), wedding dress (special wear) for female dogs/T-shirt (everyday wear), hood jumper (street wear), tuxedo (special wear) for male dogs. 4) Developed the previous six items to illustrate the research results of the study.

The objectives of this study are to develope sensibility image scales for Korean traditional motifs by quantitatively measuring their images and preference and to classify them into clusters. Data were collected via a questionnaire from seven hundred twenty five Korean undergraduate students. Re experimental materials were forty eight stimuli of Korean traditional motifs with different categories, interpretation types, composition types, and application objects. The instruments consisted of 7-point polar semantic differential scales of twenty three bipolar adjectives including preference. Data were analyzed by correspondence analysis, cluster analysis, ANOVA and Duncan's multiple range test. Re major results are as follows; image scales for textile patterns and dress designs using Korean traditional motifs were constructed. The axes of sensibility image scales for both textile patterns and dress designs were defined by quality level and degree of simplicity. Second, four clusters on the scale of textile patterns and two clusters on the scale dress designs were identified. Third, in the case of textile Patterns, the preferred cluster had high-quality and classical images, while the cluster that was not preferred had a complex image. In the case of dress designs, the preferred cluster had simple and high-quality images, while the cluster that was not preferred had complex and low-quality images.

Although a considerable amount of research on discourse signaling cues has been conducted in reading, little attention has been paid to such cues in the area of listening. Moreover, despite the solid evidence showing that cues have beneficial effects for reading comprehension, L2 listening research has produced mixed findings about the role of cues. Such discrepancies among these findings might be due in part to inadequate research methodologies as well as the idiosyncratic features of their experimental designs. However, no study, to date, has thoroughly examined the research designs of listening comprehension studies on cues. Consequently, this study critically evaluates the present state of research designs and reporting practices of studies investigating the role of cues in listening comprehension. The present study aims to provide insights into areas that require empirical attention and systematic investigation. It also seeks to encourage improved and refined research practices for future studies. This paper is organized as follows: It will first critically review the empirical findings regarding cues in the area of L1 listening comprehension. Second, it will present a critical evaluation of L2 listening studies on cues. Finally, it will address the major research design issues of currently available listening studies and provide suggestions for improvement in future research.

Bradley and Stewart(1991) considered a large class of experimental designs as multidimensional block designs(MBD's). The simplest MBD could be considered to be a row-column design(RCD). They presented the intrablock analysis of variance for a general row-column design. In this article, a generalized least squares solution for Bradley & Stewart's example is considered. In this case, the assumption is that row and column effects are random. This is an application of revised Paik(1990a,1990b)'s method. The Appendix is devoted to that revised method.

Mechanical components are to be produced with accurate dimensions in order to function properly in assemblies of a machine. Once designs of mechanical components are created, designers examine the designs by adopting many known experimental methods. A primary test method includes stress and strain evaluation of structural parts. In addition, fatigue test and vibration analysis are an important test method for mechanical components. Real experiments at a laboratory are established when products are manufactured. Since design changes should be done before producing the designs in factories, rapid modifications for new designs are required in production industries. FEM simulation is a proper choice for a design evaluation with speed at a detail stage in design process. This research focuses modeling and mechanical simulation of a mechanical component in order to ensure structural safety. In this paper, a universal joint, being used in driving axels of vehicles, is studied as a target component. A design model is created and tested in some ways by using commercial software of FEM. The designed component is being twisted to transmit heavy power and thus, torsional stress should be under strengths of the component's material. The next is fatigue analysis to convince fatigue cycles to be within the endurance limit of the material. Another test is a vibration analysis for rotational components. This research draws final conclusions from these test analyses and recommends whether the designed model is under safety condition in terms of mechanical structure.

A sequential optimization strategy based on statistical experimental designs was employed to enhance the production of cyclosporin A (CyA) by Tolypocladium inflatum DSMZ 915 in a submerged culture. A 2-level Plackett-Burman design was used to screen the bioprocess parameters significantly influencing CyA production. Among the 11 variables tested, sucrose, ammonium sulfate, and soluble starch were selected, owing to their significant positive effect on CyA production. A response surface methodology (RSM) involving a 3-level Box-Behnken design was adopted to acquire the best process conditions. Thus, a polynomial model was created to correlate the relationship between the three variables and the CyA yield, and the optimal combination of the major media constituents for cyclosporin A production, evaluated using the nonlinear optimization algorithm of EXCEL-Solver, was as follows (g/l): sucrose, 20; starch, 20; and ammonium sulfate, 10. The predicted optimum CyA yield was 113 mg/l, which was 2-fold the amount obtained with the basal medium. Experimental verification of the predicted model resulted in a CyA yield of 110 mg/l, representing 97% of the theoretically calculated yield.

This study aims to seek knitting methods that can enhance the neck design of seamless knitwear and to find out how to improve the designs by comparing and analyzing the characteristics of the knitting methods used for v-neck pullovers. The investigator analyzed the characteristics of the knitting methods and assessed the wearing sensation by using six different pieces of clothing for the experiment. The results were analyzed based on a variance analysis (ANOVA). Among the items showing significant results, the Duncan-test was used for more intensive research. As a result, while using the basic pattern of knitting methods, Experiment Clothes A ended up binding on the back neckline, and not making the hem of back. Also, the neck was the widest. In the case of the special neck, Experimental Clothes B (1:1), which had the least number of the knitting course in relation to the knitting ratio, the bottom part of the back body had the most wrinkles. According to the result of wearing sensation, the front part, the side part, and the back part showed similar results (p<0.000) in all items. Specifically, the appearance of the Experiment Clothes A (normal) in both the front and rear aspects were evaluated as the best. In the case of the special neck, the Experimental Clothes F was ranked the highest, whereas the Experimental Clothes B (1:1) was ranked the lowest. Based on the results of the study, it seems possible to provide concrete and technical data for the planning of unique and productive designs. With regard to seamless knitwear neck designs, a comparative analysis of the knitting method of v-neck pullovers will be of practical use in the development and manufacturing of the product.
