This study investigated the difference of reference price, preference and quality perception of high functional underwear according to innovation cues. High functional underwear was selected as a research stimulus due to its technological innovative characteristics. A total of 93 male university students participated as subjects and data were collected by simple random experimental design operationalized with three types of innovation stimulus cues. Two types of internal reference price perception-expected price and fair price, preference, and 9 items of product quality perception-8 functional properties and overall quality of stimulus were measured with a questionnaire. The result supported the difference of reference price and quality perception by product innovation cue. The higher cue level group perceived two types of reference price and the overall quality higher than the lower cue level group. The difference of the expected price and fair price, the influence of functional properties on overall quality, and relations of the variables were discussed in depth.

The Korean wintertime Onmapsi Campaign recommends wearing underwear, layered clothing, or thermal accessories in an indoor environment of a lower than room-heating condition. We surveyed 132 government officers, about Onmapsi wearing conditions and campaign satisfaction. The term was found to be unfamiliar to them, even if they wore underwear or thermal accessories as participants in the campaign for the wintertime office of low temperature 18-$20^{\circ}C$. They wore thick shirt/pants or cardigans/sweaters; however, underwear or thermal vests was worn relatively less. They wear 2.9 layers on top and 1.7 layers in bottom in average. They have their own methods to keep the body warm, which are using 1) functional thermal clothing, such as turtleneck shirts of heat technology new material, 2) functional thermal accessories, such as warmer and muffler, 3) functional office goods, such as a thermal computer mouse and blanket on the desk. The campaign requires more advertisement, a revision on the details of the proper wintertime indoor environment, and develops the varieties of Onmapsi apparel.

This study evaluated the thermoregulatory properties of functional thermal underwear ('heating underwear') in markets using a thermal manikin and human wear trials. One ordinary thermal underwear (ORD) and two functional thermal underwear (HEAT1 and HEAT2; manufactured goods, HEAT1: moisture absorbing heat release mechanism, HEAT2: heat storage, release mechanism) were chosen. Thermo-physiological and subjective responses were evaluated at an air temperature of $5.0{\pm}0.5^{\circ}C$ and air humidity of $30{\pm}5%RH$ with five male subjects ($21.6{\pm}1.3yr$ in age, $178.0{\pm}5.9cm$ in height, $68.2{\pm}5.9kg$ in body mass). Experimental conditions consisted of four ensembles that included winter clothes (Control: no underwear, ORD, HEAT1, HEAT2). Water-vapor resistance was greater in fabric of HEAT1 than others. The results were: 1) Total thermal insulation (IT) using a thermal manikin were not greater for HEAT1 (0.860clo) and HEAT 2 (0.873clo) than for ORD (0.886clo). 2) There were no significant differences in rectal temperature, mean skin temperature, heart rate and total body mass loss between the four conditions. Microclimate clothing temperature on the back was greater for ORD than for HEAT1 and HEAT2. Subjects felt more comfortable with HEAT1 than for others at rest. HEAT2 was higher in microclimate humidity when compared to other conditions. The results suggest that thermoregulatory properties of 'heating underwear' in market did not differ from those of ordinary thermal underwear in terms of total thermal insulation and thermoregulatory responses in a cold environment.

This study attempted to analyze trends of structural changes in the front middle part of men's underwear and get basic data for the development of men's underwear patterns. In terms of a research method, the structure and pattern of the front middle part of men's underwear were analyzed by referring to the design and description of the drawing, focusing on men's underwear which targeted to isolate penis from scrotum among the 'men's underwear' or 'functional men's underwear'-related patents. According to the study, three topics were obtained as follows: a support attached to the inside of the front middle part; inner cloth attached to the inside of the front middle part; change in the structure of the front middle panel. The aspects by the specific topic targeted to isolate penis from scrotum and prevent the scrotum from adhered to a thigh are as follows: 1) When a support is attached to the inside of the front middle part, the following three methods are proposed: Penis isolated from scrotum by a rest which is designed using the band; penis and scrotum rested in the band and in a pocket respectively; protruded rest inside the front middle part of the underwear. 2) When an inner cloth is attached to the inside of the front middle part, the following methods are designed: A pocket-type inner cloth is attached; isolation of penis hole from the scrotum pocket using a rectangular separator; U-shaped pocket designed to rest penis and scrotum is attached. 3) Regarding change in the structure of the front middle panel, the integration of penis and scrotum resting parts can be divided into two cases: Securing a space using wrinkles; keeping it voluminous using the vertical line. In this all-in-one penis and scrotum-holding type, in addition, different front panel patterns were applied.

Due to recent changes in increased life expectancy, economic power and social development, the new senior generation (focusing on people in their fifties) represents a new market power with strong competitiveness. The new senior generation is the generation after the baby boomers, with characteristics that include a high-level of education, increased income, a high-level of consumption, increased assets, self-fulfillment desires and individuality. Demands in the senior fashion industry are expected to gradually increase and the underwear industry that targets the new senior generation is expected to grow rapidly. These demands will require product development for the new senior generation based on emotional and socio-cultural characteristics. The current new senior underwear market is under the process of R&D with a focus on body shape changes; however, there are limited studies on emotional and socio-cultural approaches. This study formulates a basic design plan for different age groups based on an analysis of the situation of bra wear (current inconveniences, demand and needs) by women in their fifties and over. Subsequently, a functional active bra top that considers activity and comfort was proposed for women in their fifties, an all-in-one foundation bra top that shapes the body was proposed for women in their sixties, and comfort bra tops that are comfortable and easy to put on and take off were proposed for women in their seventies and over.
