소아용 안경의 temple부분은 알맞는 탄력성이 있고 bridge부분은 충분한 견고성이 있어야 하여, 옥형 사이즈나 temple의 길이는 적어도 3-4종류가 있는 안경테로 하여야 한다. 또 pad는 높아와 폭 및 각도 조정이 가능한 것을 선택해야 하며, pad와 temple의 접촉에 대한 보정력이 충분한 것을 선택해야 한다. pad의 fitting은 비능부(鼻陵部)에 작용하는 안경중량의 크기가 압력에 비례하므로 pad의 전면(全面)이 비능부(鼻陵部)에 균일하게 접촉할 수 있도록 fitting해야 하며, pad는 접촉면이 넓은 것이 좋다. 렌즈의 선택시 주의할 점은 렌즈의 도수가 강해 질수록 안경 총중량에 차지하는 렌즈중량의 비율이 커지므로 무게는 될 수 있는대로 가벼운 것을 선택해야 하고, 최소직경 생지렌즈로 하는 것이 좋으며, 깨어지지않고, 안전성이 뛰어난 프라스틱 렌즈를 사용하는 것이 적합하다.

Pantyhose is a close-fitting garment. Consumers are highly sensitive to any progress done in fitting their lower body and increasing comfort. However, pantyhose manufactured in Korea are only one-sized. The purpose of this study is to suggest the size designation of pantyhose, using new human body measurement data which were gained from the Year 2004 SIZE KOREA project. For the purpose of this study, the ISO standards and JIS standards were reviewed and questionnaire was carried out to manufacturers and distribution companies. The results are as follows: First, for a difference with size standards established in 2002, applicable age range was expanded from 15 to 70 year-old women to entirely include persons who wear panty hose. Secondly considering the actual condition that panty hose is producing in single size in most companies due to its elasticity of material, number of size was reduced from five to four. Thirdly basic parts of body which were applied to panty hose are height and hip girth. And size of panty hose is decided by a chart which is composed of height-axis and hip-axis.

Numbers fitting-curve equations have been proposed to predict soil-water retention curve (SWRC) whose parameters have no definitude physical meaning. And these methods with precondition of measuring SWRC data is time-consuming. A simplified directly method to estimate SWRC without parameters obtained by fitting-curve is proposed. Firstly, the total SWRC can be discretized into linear segments respectively. Every segment can be represented by linear formulation and every turning point can be determined by the pore-size distribution (PSD) of Mercury Intrusion Porosimetry (MIP) tests. The pore diameters governing the air-entry condition (AEC) and residual condition (RC) can be determined by the PSDs of MIP test. The PSD changes significantly during drying in SWR test, so the determination of AEC and RC should use the PSD under corresponding suction conditions. Every parameter in proposed equations can be determined directly by PSD without curve-fitting procedure and has definitude physical meaning. The proposed equations give a good estimation of both unimodal and bimodal SWRCs.

The mask-face interface design should consider the face shape to improve the half mask respirator's fit ratio. This study tried to design the mask-face interface using recent Korean face data. By using the data of 1536 men's 3D face scanning (Size Korea data), head clay mock-up was made and mask-face interface line was extracted from this head mock-up. Using this interface line, the half-mask prototype was made. According to the quantitative fitting test, the proposed mask was found to be well fitted (average fit-ratio > 100). The proposed method had two advantages. 1) The method could use massive head-related anthropometric data like Size Korea data. 2) The qualitative fit test (observation) could be conducted very quickly by fitting the prototype to the head mock-up. However, this method also had several limitations. 1) The head clay mock-up could be different according to the mock-up maker. 2) The average values of the head-related anthropometric data were used to make the head mock-up. Small and large size head mock-ups should be made and tested.

크기 분포를 가진 금 나노 입자 콜로이드의 소광 스펙트럼을 미 이론으로 계산하고 실험과 비교하였다. 입자 크기 분포를 고려한 계산이 크기 분포를 고려하지 않은 계산보다 실험과 더 가까움을 확인하였다. 최소 자승법을 이용하여 실험에서 얻은 소광 스펙트럼으로부터 입자 크기 분포를 이론적으로 도출하였다. 이렇게 얻은 입자 크기는 입자 지름이 10에서 28 나노미터인 경우 투과전자현미경 분석 결과와 잘 일치하였다.

This study analyzed a somatotype of teenager's that was suitable to improve the reality of a virtual model size. We analyzed 843 teenagers 12-18 years old from the 6th Size Korea data. First, factor analysis was done for abstracting new criteria and dividing the somatotype; subsequently, we selected the waist height proportion to stature (body proportion) and drop (torso shape). Next, the cluster analysis was done with these criteria; subsequently, 5 body proportion types and 7 torso shapes were distinguished. A virtual model size for 4 somatotype with more than 50 persons was also designed by a regression analysis that constituted sizes for each factor. The designed model size was compared with body size as well as with Clo's virtual model size. The research model showed a high similarity in sizes with body as well as improved reality over the Clo model that presented size problems such as low waist height, bigger bust, and smaller thigh circumference than the real body.

This study investigated the usage and product conditions of clothing companies and online dummy companies for the development of fitting dummy for South Korean women's wear in their 50s and 60s. These women-targeted apparel companies mainly used nude-sized torso type and torso crotch type made of FRP material. The frequency of use of the dummies was high, while the user satisfaction was moderate. Users expressed dissatisfaction with the inaccurate reflection of the body shape according to the KS sizing system and the measurements such as the front and back intercye, upper arms, abdomen, crotch, and waist back length. Upon survey, 73.7% of the respondents answered that development of the dummy and the appropriate age for it is 50 to 54, and they preferred the torso crotch form. In the production of online dummy companies, the torso crotch type and torso type were most widely produced, and polyurethane, FRP, and recycled paper materials were used. The size of dummy was expressed in numerical type, and 6, 7, 8, 9, 10, 12, 14, 16, 18 and 44, 55, 66, 77, 88 were being produced. Even models of the same size had significant deviation, especially in the waist circumference. Also, there was no dummy reflecting 25%~75% center interval to the KS garment sizing standards of women in their 50s and 60s. Therefore, it is desperately necessary to develop a fitting dummy for KS clothing sizing system that reflect their body sizes and shapes.

입도분포는 토양의 수리특성을 추정하는 데 많이 사용되고 있다. 본 연구는 다양한 가정조건을 가진 9개의 입도분포모형을 가지고 한국토양을 대상으로 어떤 모형이 가장 잘 입도분포를 모사하는지를 조사하였다. 4개의 추정변수를 가진 Fredlund모형, 로지스틱성장곡선, 그리고 Weibull분포가 다른 모형에 비해 PSD를 잘 모사하였다. 특히 추정변수가 없는 로지스틱 성장곡선 함수가 좋은 모사를 나타낸 것이 흥미로웠다.

The purpose of this study is to dvelop the basic pattern of wome which are fitting for 75A. The collected data were statistcally processed usig the SPSS 10.0 for Mans Standard Deiation, Cronbach's $\alpha$, etc. This study suggested a size chart for body measurement for constructing basic brssiere patterns with size of 75A. The construction of this experimental brassiere were lower cup, upper cup, front panel and wing and characterized by a round cup wired as well as a full cup embrcing the entire breasts. The drafting method for constructing basic brassiere patterns for 75A was completed by selecting a total of 11subjects, and two wearing tests were carried out with the subjects. the dimensions and shapes of the basic brassiere pattern suggested in this research proved to be fitting and to have a wearing effect that brings together and supports the breasts.

This research aims at finding out situation on purchasing clothes for kids, size recognition and fitting to provide basic data in order to establish standard sizes for kids' clothes. A survey was conducted to 360 mothers who have children ranging from first to third grade in elementary school on clothes purchasing method, wearing situation, criteria in deciding size and fitting preference. In terms of data analysis, frequency, percentage, mean, $X^2$-test, ANOVA and Duncan-test were used via SPSS PC program. The result is as follows; 1. While the recognition on brand was high, the recognition on body size was low: as a result, it is believed that it would be effective to mark the weight along with the brand. 2. Many times, they would select one or two size bigger on all items and they would go for a regular or one that fits as far as filling is concerned showing that it is different from adult clothes. 3. As far as obese kids, they would choose based on the diameter, so the diameter item is right but they are too long in general. The length question should be given special attention when manufacturing clothes for obese kids.
