This study presented functional designs for development of functional compression wear for men in their forties based on body muscles as well as designed 2D patterns using 3D standard body form data of men in their forties. Patterns with an optimal stretch rate were proposed through a comfort evaluation. Different material was used for different areas such as the sports ability strengthening areas including body parts that often move for sports (such as the shoulders, abdomen and lower arm), areas that require ventilation for perspiration (such as the chest and back center, and armpits), and stable form areas (such as the chest, waist and elbows). The front and back surface areas of the developed pattern was an average 102.4% size compared to the body surface area. The results indicated that the 90% reduction pattern showed changes in pressure value according to area of movement, had the best breathability when worn, and had the best, most comfortable fit compared to the other subjects. The clothing pressure values of the pattern were around 22.1-23.4mmHg for the arm area (which has a big movement range and has many muscles) and 10.4-11.8mmHg for chest and abdomen areas related to major organs and breathing, indicating appropriate clothing pressure. A compression wear top pattern with pressure appropriate to the target age range and excellent appropriateness for the body form will be developed for men in their forties. A study method will be proposed to develop design technology for ergonomic compression wear tops with excellent fit and comfort.

A forklift is a powered industrial vehicle used to lift and move materials over short distances. Nowadays, almost all forklifts are equipped with an automatic transmission due to its improved operator comfort and increased productivity. Thanks to marked improvement of transmission control unit equipped with highly-advanced microcontrollers, recently developed automatic transmission for forklift have various auxiliary functions such as creep, auto retardation, and automatic shift with excellent shift quality. This paper deals with the creep function which enables one to maneuver a forklift at the designated low speed by slip control of clutches. The design of creep function was based on four modes of creep operation depending on the status of the operator's shift lever and accelerator pedal. Control algorithms and control parameters for each mode were designed to achieve the desired static and dynamic performance. Vehicle test for the designed creep function was carried out with an independently developed embedded controller. Test results confirmed good creep speed control without speed error at a steady state with a mild shift shock during mode changes by stepping or releasing the accelerator.

The purpose of this study is to develop an aesthetic and functional bicycle wear for new senior women in their 50s and 60s. Based on the results of the survey, we developed bicycle wear that is friendly to bicycling posture and reflects the preference of new senior women. The results are as followed: First, emphasis is placed on the simple and functional design of the experimental wear consisting of jacket and pants. Jacket is different from the color scheme with the armhole princess line in order for the waistline to look slim. Pants are designed to hold the leg muscles tightly in order to help reduce the muscle fatigue on the bicycle ride. Second, cutting lines and coloring materials are used for the wearer to look slim and the safety of the wearer is planned to secure by inserting the reflective material along the cutting lines on the bicycle ride. Third, the pattern of the experimental wear is designed in consideration of the riding motion of the bicycle. Jacket is designed to have back length longer than front length as compared to the bicycle wears available on the market. Sewing lines in the armpit are designed to be eliminated in order to move the arms smoothly on the ride. Pants are designed to minimize the seam line in consideration of the movement of muscles and ligaments and the experimental wear is produced by combining the material with the functions of cool comfort and stretch.

This study was conducted to analyze the wearing condition on gloves for pilots and to suggest the developments for pilot gloves design. This survey was performed with 99 pilots and the questionnaires included items about discomfort, materials and problems when wearing pilot gloves. The respondents felt uncomfortable on the finger tip, the hollow area of the hand and the end of thumb when they move their hands with the gloves. They replied that the finger length, palm length, and circumference of the fingers did not match well. Also they complained there was severe abrasion in the tip of the thumb, finger tips and the middle of the palm of the gloves. The result of these analyses supports the following suggestions. It is necessary to improve durability by applying the additional materials to the severely worn parts. Punching on the glove materials could improve sweat rate and ventilation, and careful washing should be accompanied to prevent the occurrence of linters and transformation after laundering. And it is needed to prepare an accurate and more diversified size system and to design the gloves fitted to the individual hands. With these in mind, it is required to propose solutions for pilot gloves with reference to the survey results in order to design appropriate pilot gloves in terms of movement, size and material. It was concluded that an analysis of the wearing condition and developments are useful for ergonomics pilot gloves design.

This study aims to configure what dimensions make up for smart phone after service quality, and how this service quality affects customer satisfaction and customer loyalty. Smart phone market is a market of the device leading the digital convergence as well as positioning itself as one of the national growth driving industry. To survive in this matured market, companies should have to respond actively to radical changes and customers needs in the so-called Smart Revolution environment. Lately, however, the smart phone market is prospected to move from growth phase to mature phase by the scholars. In order to proactively respond to the change in such market condition, companies need to provide absolute advantage in customer loyalty over their competitors by revolutionizing the after-sales service quality. Qualified A/S will lead to service satisfaction and achieve customer loyalty. The empirical analysis results obtained through A/S quality are as follows : First, human quality (attitude, expertise, problem-solvability), environment quality (handling agility, convenience, comfort), service policy quality (quality guarantee, additional service operation) are dimensions that make up for A/S quality. Second, A/S quality dimension showed a significant positive influence on service satisfaction and A/S satisfaction showed a positive influence on customer loyalty as well. Based on this empirical study, we propose some implications for A/S quality improvement. First, human quality dimension has relatively higher influence on A/S satisfaction in case of free A/S, so companies need to solve the product problem completely when consumer's first visit by continual employee education. Second, in case of paid A/S, the service policy quality-especially A/S Warranty period- has higher influence on A/S satisfaction.

This research was designed to explore the meaning of housing among Korean Chinese in Harbin, China. In particular, the meaning of housing was examined by using the pathway approach. Utilizing qualitative research methods, this study administered the in-depth interview on the oral history of an individual life, and the 5 elderly persons in their 60s and 70s participated in the individualized interviews that were conducted from May 28 to 31 in 2010. The main findings of meaning of housing were as follows; 1. Similarly to the meaning of housing in 1970s and 1980s in Korea, house was viewed as both a shelter for family members and relatives and a place for their comfort. 2. Prior to multi-story residences, Harbin had only 3 different forms of single-story houses available; Chinese style with Kang and soil room(地室), Korean style with 'Ondol', and Russian style with open floor and Pechka, The promotion at work enabled participants to move to multi-story residences, their moving time varied from 1970 to 1991, and the residential moving determined their current housing status. 3. Multi-story residences were available around 1970s, floor-heating system was introduced from 1990s, and high-rise apartments were built from 1998. Korean Chinese(朝鮮族) weren't satisfied with the spatial composition of individual units embedded into the Chinese culture, especially, entrance, kitchen, bathroom and veranda. 4. Based on assimilation through socialism, adaptation to socialist society and capitalist acculturation, the lifestyles of the interviewees were categorized into five types - capitalist-proactive(Ms. KS), socialist-pragmatic(Ms. J), socialist-inducive(Ms. KY), family centered-conservative(Ms. L), and socialist-adaptive(Ms. P). This study implies that housing-related services for Korean Chinese are necessarily provided so as to embrace their life style and cultural identity in housing design, and further studies need to be explored.

Exhibition space emphasizes the experience in the space rather than viewing or appreciation of visitors. Because the experience spaces in today's life are limited, people experience rest, comfort, and sometimes extraordinary space experience through exhibition space. Exhibition space has changed from a static place to a space where visitors move and act with the exhibits to freely feel the space. Also, the static space expressed only with illumination and shadow becomes a new space different from daily space for users. This study analyzes the characteristics of phenomenological expression through such user-oriented exhibition space. This study is to analyze the characteristics of phenomenology through the exhibition experience space structure. It is to analyze and study on the characteristics of phenomenological expression of the exhibition experience space structure centered in the opinion of Merlo-Ponti that considers the experience of body among 'characteristics' discussed based on the study of the phenomenological experience published up to date and the viewpoint of Steven Hall that sees light as a subject of creating the space. This study is also considers how the perception of the experiencer is built in the correlation between the phenomenology and exhibition experience space by studying the relationship of the experiencer that is the common point of the exhibition experience space structure and the characteristics of phenomenological expression and analyzing the common point and difference of them. It also focuses on the space of dark whether forming any light rather than looking at the light which is the sense factor among the characteristics of phenomenological expressions. Thus, the purpose of this study is to analyze the case on whether there is any light or not applied to the exhibition experience space grounded by the theoretical materials of Merlo-Ponti and Steven Hall based on the characteristics of phenomenological expressions in the exhibition experience space structure and, based on the result, to set up the basics on the characteristics of phenomenological expressions in the composition of exhibition experience space.

As fashion is a visual symbol that reflects age and culture, cosmetics and beauty are other products of fashion that move the time. A dominant designer of 20th century Chanel does not merely stand for a design innovation of fashion industry that created a vogue. With liberation from corsets that cruelly exaggerated and suppressed female body, meaning of style in modern fashion could be found not only in clothing but also in make-up and hair style. Simplest possible comfort was aimed for, and philosophical concepts of minimalism, modernism and dandyism were incorporated with clothing, cosmetics, perfume, make-up and hair style to establish aesthetical concept of total fashion. Chanel thought of cosmetics as an accessory with essential role and although her philosophy on cosmetics and beauty is not as well known as her clothing style, the authors believe that understanding such philosophy will become an important stepping stone for accurately understanding Chanel style. The purpose of this study is to firstly illuminate the idea that cosmetic beauty can be studied with artistic and philosophical background in addition to its functional side and to secondly investigate the reason why Chanel style is being loved by women with such durability over time and space and with what tempo fashion is connected with cosmetic beauty culture and develops. Third, by studying the ways in which characteristics of Chanel's fashion philosophy are expressed in cosmetics and beauty culture, this study aims to accurately understand Chanel's philosophy on cosmetics and beauty. The meaning of this study can be found by showing the evidence that globalization of Korean fashion beauty culture can be achieved only when cosmetics and beauty culture moves with an intimate connection to clothing culture.
