The purpose of this research is to develop the design, pattern and size system of brief as a measurement garment in order to obtain more precise silhouettes and sizes of the body in 3D measurements. The results of this research are as follows: First, nylon/lycra materials which elasticity is equivalent to 18%(wale) and 27%(course), were selected as a material for briefs to minimize possible error in measurement and deformation of body shape caused by looseness or tightness in its measured parts. And T-back style design was selected, of which briefs neither deform human body nor cause overlapping or excessive tightness when was put on the measurement garment over it. Second, different darts for men and women were adopted into the pattern in consideration for the shape of hip. Third, the waist band of briefs was located between the waistline and abdominal girth line so that it didn't interfere with measurement, and using a wide band of 40mm minimized the tightness of the human body. In addition, the stitch lines and sewing procedure were simplified to minimize the deformation of body shape resulting from inseams and stitch lines. Finally, for the size of briefs, 6 cm intervals were set on the basis of the waist girth and 8 kinds for men and 6 kinds for women were selected in descending order of appearance rate by the interval sections. English T meaning T-back design and numbers representing the waist girth were marked in parallel for the name of size.

The purpose of this study was to analyze and determine the relationship between physiological responses including blood flow rate and garment pressure, and the feeling of restrictive tightness associated with the wearing skinny pants as a popular clothing style. Evaluation was based on material type, posture and activity type, and body part location. Five female college students took part in this research. Five kinds of experimental clothes with waist measurements of 66cm were chosen. An analysis of the selected skinny pants demonstrated the degree of the whole looseness was higher in this order: clothing type A>B>D>C, and E with E being knitted cloth. Garment pressure was the highest in the front knee portions and was lowest in the outside thigh region. Garment pressure was highest in this sequence : clothing type C>=D>A>=B>E. In terms of posture and activity types, garment pressure was the highest when research participants were crouching, and was the lowest when standing. The blood flow rate was highest in this order: clothing type E>D>B>A>C. Type C skinny pants impeded blood flow and demonstrated the tightest and most restrictive relationship. Blood flow rate varied depending on the type of movement and was highest in this order: getting up, rowing, kicking, jumping and O-shaped leg posture. The results of subjective pressure evaluation demonstrated that pressure was highest in this order: E>=C>B>A>D. These results suggests the need to improve on the patterns and the material design in the area of the front knees. The degree of the looseness when wearing skinny pants did not always correspond to garment pressure or subjective sensation.

This study helps in the production of brassieres suitable for female adults by researching the actual wearing conditions and purchasing status, satisfaction rate, and preferences of female college students in their early 20's. The collected data was analyzed by a SPSSWIN 13.0 Program and the results of the research are as follows. 1. There is a noticeable difference between the breast satisfaction rate and breast size, in addition the satisfactory rate was higher in the normal breast size or a little ample size than in the very small or very big size. According to the shape, the satisfactory rate for the breast appeared to be high in the case of the recognition and evaluation of the hemisphere type than the flat, cone, pop out, and downward type. 2. For fitness, the looseness at the top of the cup (pressed between the breasts at the upper part of the front middle), pressing and looseness at the upper sides of the cup, inappropriate size of the cup, tightness of the wings, tightness at the bottom round of the breasts, the narrow width of the wire, wide space of the shoulder strings, and the sliding of the shoulder strings had problems that needed improvement. 3. The major priorities for purchasing brassieres are size, fitness, and aesthetic qualities. As a result, the size and the fitness are more important than the trend or decorations since the brassiere has the function to support the breasts that shows that hygiene and sanitation are recognized as an important standard for undergarment selection. The size and the fitness are important factors regardless of breast types in the examination of the selection standards of the brassieres for each breast type, but the cone and hemisphere types have higher preferences for design; the pop out type has more considerations for the material of the cloth. The result show that appearance is more important for smaller breasts, but the functionality of the brassier is more important than the appearance for medium and larger breast sizes.

The hydrogen atom transfer reaction between substituted methane, $CH_3X,$ and its radical, $CH_2X(X=H,F,CH_3,CN,OH\;and\;NH_2$ was studied by MINDO/3 method. The transition state(TS) structure and energy barriers were determined and variation of the transition state and of the reactivity due to the change of X were analyzed based on the potential energy surface characteristics. It was found that the greater the radical stabilization energy. the looser the TS becomes; the TS occurs at about 15% stretch of the C-H bond, which becomes longer as the radical stabilization energy of $CH_2X$ increasers. The intrinsic barrier, ${\Delta}E*_{x.x},$ of the reaction with X was found to increase in the order $H The degree of bond stretch of the C-H bond stretch of the C-H bond at the TS also had the same order indicating that the homolytic bond cleavage of the C-H bond is rate-determining. Orbital interactions at the TS between LUMO of the fragment $C{\ldots}H{\ldots}C$ and the symmetry adapted pair of nonbonding, $n{\pm}(=n_1{\pm}n_2),$ or pi orbitals of the two X atoms were shown to be the dominant contribution in determining tightness or looseness of the TS. The Marcus equation was shown to apply to the MINDO/3 barriers and energy changes of the reaction.

한국 사람들에게 억울은 자신이 처한 상황 또는 마음상태를 묘사하는 유용한 수단이자 화병에서 자살에 이르기까지 한국인의 정신건강에 부정적인 영향을 미치는 중요한 원인으로 여겨지고 있음에도 불구하고 한국 사람들이 어떤 경우에 억울함을 느끼며 어떤 방식으로 이를 해소하는지, 억울하다는 것을 어떠한 의미로 받아들이는지에 대한 실질적인 연구는 부족하다. 이에 본 연구는 억울에 대한 이해를 보다 명확히 하기위해 2개의 연구를 진행하였다. 연구 1에서는 한국인들이 억울이라는 말을 사용하여 표현하는 상황과 억울을 경험하는 전반적인 과정을 조사하여 억울 경험의 구조와 특성을 확인하였다. 그 결과 억울함은 자신의 일을 주관적으로 부당하다고 인식하고 여기에 부정적인 정서가 따름으로써 경험되는 보편적인 과정을 거쳐 발생하였다. 하지만 어떠한 상황을 부당하다고 여기는지 그리고 억울을 어떻게 표현하며 해소하는지는 각 문화권마다 다르게 나타날 수 있다. 따라서 연구 2에서 억울 경험 과정에 연관된 문화적 맥락(주체성-대상성-자율성 자기관, 개인주의-집단주의 가치관, 느슨한-경직된 체계특성, 권위주의 성향)이 억울에 미치는 영향을 실증적으로 검증하고 이상의 결과를 종합하여 억울의 특성에 대해 논의하였다.
