Due to the financial crisis in 2008, the world economy collapsed leading to an increase in oil prices and a decrease in freight by shipping. To overcome this crisis, major shipping companies ordered larger ships, changed their trading route and improved operating of ships to overcome deficits. In particular, low-speed navigation was much favored by many companies so that it can reduce fuel consumption. However, the long-term operation of high-speed optimized engines in low-speeds has affected the jacket cooling fresh water (J.C.F.W.) system as they fail to maintain the normal operational temperature. The temperature of J.C.F.W. system dropped leading to low temperature corrosion. As a result, when the engine is operating at minimal load the functioning of existing J.C.F.W cooler is decreased and the use of fresh water generator is substantially limited. Therefore, an improvement in the functioning of J.C.F.W. system is necessary. In this paper, in order to review the improvements required for the operation of J.C.F.W. of low-speed operating marine diesel, an experiment was conducted by comparing and analyzing the results of the main engine J.C.F.W. system of a Panamax class bulk carrier 82k and a Cape class bulk carrier 180k by installing and uninstalling the J.C.F.W. Cooler. Thus, this paper proposed an improved design of the J.C.F.W. system that is suitable for the present low-speed operation.

Exaggerations have always been seen in the past and present. In the past, they represented wealth and high social status, but now they are being used to express one's beauty and personality. This has led to the diversity in design through widening each person's emotions. Likewise, exaggerations have been changed from the past to the present and so will they in the future. This study focuses on proposing patterns to enhance the utility and practical use of exaggerated jacket designs and its methods are based on documents and preceded studies. Pattern making is composed of drawing patterns and showing their forms by basting - which are a technique that is explained in this study's outcome - and the basic pattern is the style of Wan Suk. Suh. Jackets are made with exaggerating factors in the women's collections of 2011 F/W and are designed for various ages. With the knowledge of structuring a jacket, anyone could easily follow the instructions. In the end, he/she could elevate the ability to express, use practically and apply this idea in general fields of fashion industry.

The purpose of this study was to investigate the wearing sensation and satisfaction of high school girls winter uniform' jacket. The subject participated in the study were 599 high school girls attending four different schools. The fabrics were divided into two parts of stretch and non-stretch woven fabrics. The results were as follows: 1. The high school girls showed body image distortion that she recognized herself as fatter than her real body type. Especially, this was severe in the slim body type. 2. In the aspect of the satisfaction for uniforms' jacket made with stretch fabric and non-stretch woven fabric. the elastic fabric was more satisfied than the non-stretch one because its width and length was shorter and fitter than non-stretch one. 3. When they wore the school uniform jacket, the wearing sensation of one made with stretch and non-stretch woven fabrics showed significant differences in arms hole when raising hands, front bust when carrying backpack on their back, backs while studying at desks, the upper arms and the elbows. 4. As for the alteration of school uniform jacket, the non-stretch woven fabric was appeared to be altered more than the stretch one.

This study investigates the wearing trend and purchase facts for adult females in their 20s and 30s along with their fitting satisfaction for woven jackets and circular knitted jackets. A questionnaire survey on consumers investigated satisfaction with jackets according to clothing materials and repair trend after wearing. Subsequently, a preference for circular knitted jackets was shown higher than woven jackets. Females in their 20s preferred woven jackets than those in their 30s; however, the latter preferred circular knitted jackets than the former. For woven jackets, they showed the highest satisfaction with size; however, for circular knitted jackets, they showed the highest satisfaction with fitting. In the question on their satisfaction by jacket part, satisfaction with circular knitted jackets was higher in all items except for bust measurement, bottom edge measurement, elbow circumference, shoulder width, and clothes length. Circular knitted jackets had lower repair rates than woven jackets and woven jackets had significant differences by age in satisfaction with back width. The research results indicate that females in their 20s and 30s who value fit preference and practicality will increasingly wear knit clothes. Therefore, we can address the fitting satisfaction requirement of females in their 20s and 30s by taking the clothing material properties of circular knitted clothes into consideration. In addition, further research is required on jacket patterns in consideration of clothing materials.

The objective of this study is to analyze the characteristic of a functional design for a commercial outdoor brand jacket based on 3 types of functions : windproof, waterproof, and cold proof. To analyze the design and fabric characteristics of outdoor jackets by function, 903 men's and women's outdoor jacket images were selected from the catalogues during S/S 2009 - F/W 2011 of the 6 brands: The North Face, Columbia Sports Wear, Kolon Sports, K2, Arcteryx and Mont-Bell. These brands were selected based on their high market share and brand awareness of the outdoor brands in Korea. In this study, design elements analysis was conducted as following 8 elements: hood/collar height/central front flap/waistline/pocket location/ventilation for the body part/sleeve patterns/cuff for the sleeve part. Fabrics were analyzed by the frequency of fabric types used in the 3 jacket types. According to the result derived from the analysis of the six brands of outdoor wear jacket design trends by year, detachable hood and a co-use of velcro and elastic bands have been mainly designed for all of windproof, waterproof, and cold proof jacket to all in order to respond quickly to changes in the external environment. For reinforced storage function on trekking, the number of pockets has been gradually growing, and a function was being developed to connect an electronic device to a pocket. The method, result, and collateral observations relevant to each of these phases are described. Outdoor jacket design characteristics were investigated for outdoor brands, which can provide data to suggest more accurate functional design, and satisfy functional design needs. In this regard, this research was significant in the sense that it suggested preliminary data to reconsider competitiveness of the brand products.

In this study, a procedure of performance-based design for the seismic retrofit of reinforced concrete columns strengthened by steel jackets has been presented. In order to predict the target displacement of retrofitted columns, a nonlinear analysis of reinforced concrete columns retrofitted with steel jackets has been developed based on a segmental model with the fiber cross-sectional approach. The seismic displacement level of retrofitted columns is estimated both by the direct displacement-based design method and by the displacement coefficient method. In examples of seismic retrofitted columns, the current seismic retrofit procedure gives good results in improvements of displacement levels and displacement ductilities of retrofitted columns.

In this paper, we consider the encoding scheme of Low Density Parity Check codes. In particular, using the Jacket Pattern and circulant permutation matrices, we propose the simple encoding scheme of Richardson's lower triangular matrix. These encoding scheme can be extended to a flexible code rate. Based on the simple matrix process, also we can design low complex and simple encoders for the flexible code rates.

Subjective sensorial experiment was executed with 43 subjects to find the relationships between the sensibility of jacket styles and the handle of wool fabrics. The handle and sensibility of wool fabrics were significantly different according to the wool types, and the handle was defined as two axis of Wild/Exquisite vs. Thin/Thick. The sensibility of jacket styles was different by the types of jacket styles, and the jackets were displayed in the 2D of Masculine/Feminine vs. Country/urban according to the factor analysis using 8 sensibility words. The best-appropriate jacket styles for each wool fabrics were converged into several jacket styles, and it was found that the wool fabrics were divided as for all-purpose or for specific-end usage. For the results of correspondence analysis of the matrix for the best-appropriate jacket style for each wool fabric, the jacket styles and wool fabrics together were grouped as 4: Striking and Yang, Striking and Yin, Plain and Yang, Plain and Yin.

The purpose of this study was to investigate the effect of perceiver's gender, clothing, and hairstyle on the visual evaluation of men's professionalism and preference. A quasi-experimental method by questionnaire was used. The experimental design was a $2\times8\times2$ (perceiver's gender $\times$ clothing $\times$ hairstyle) factorial design by 3 independent variables. The stimuli were 16 photographs of a man in his twenties. The upper clothing of the man included tailored collar jackets in beige and dark blue colors, and jumpers and sweaters in beige, dark blue, and red colors. The lower clothing of the men included jean pants. Two types of the hairstyles included short hair and medium length hair. The subjects were 208 men and 223 women in Seoul, Korea. Wearing a beige sweater with jean pants was evaluated high in intellectual image, a red jumper was perceived low in intellectual image, and a beige tailored collar jacket was evaluated low in potent image. Men's short hairstyle was evaluated to be more professional than the medium length hair. Male perceivers liked short hair more than medium length hair, but female perceivers evaluated both hairstyles similarly. In the case of women, the preferences of tailored collared jacket and soutien collared jumper were similar, but jumper was preferred to jacket in the case of men. Male perceivers showed more positive feedback towards jean pants with soutien collared jumper than jeans with tailored collared jacket, which indicated that men showed more conservative attitude towards the outfit than women. The man who was wearing a jumper with short hair was evaluated positively and the man who was wearing a jacket with medium length hair was evaluated negatively when the attires were coordinated with jean pants. In conclusion, medium length hairstyle with a beige jacket and short hairstyle with a red sweater were evaluated as professional image; and the results indicated that clothing and hairstyle interact with each other and influence the evaluation of professionalism.
