최근 한의학에서는 인체를 8가지 체질로 나누는 8체질의학에 대한 관심이 높아지고 있다. 그런데 8체질은 맥진에 근거하여 판별되므로, 8체질의 판별 및 병증의 치료를 표준화시키기 위해서는 객관적인 8체질의 특성을 찾아내어 이것을 표준화시키는 일이 절실하다. 본 연구에서는 맥진을 통하여 8체질로 분류된 후 8체질 침법에 따라 치료 중인 남자 환자들의 신체적 특징과 증후 등을 설문을 통하여 문진하였다. 그리고 일원배치 분산분석법에서 유의한 문항들에 대하여 다중비교법을 이용하여 8체질 사이의 평균 차이를 표로 나타내었다. 이 분석에서 유의하게 나타난 문항들은 실제의 진단 및 치료에서 관찰되어온 8체질 특성과 잘 일치하고 있었다.

The objectives of this study are : (1) to measure the level of economic stress perception in Korean farm households. (2) to identify the effects of related variables such as socio-demographic variables and economic stability. The data from 505 farm households' wives was analyzed using statistical methods such as frequency, correlation, oneway ANOVA, lease significant difference test, and stepwise multiple regression. The major findings are as follows : The mean value of economic stress perception on the 505 wives was 33.5 points out of a possible 100. Among 3 subsectors, income stress perception had highest score. Socio- demographic variables such as family size, type of farm household, financial manager, debt, credit . grant assistant, wife's age, and educational level of the wife had a significant difference on the economic stress perception of wives in the ANOVA analysis. So did the objective and subjective evaluation of economic stability. As a result of multiple regression analysis, economic stability, debt presence, and wife age were verified explaining 23% of the variance of economic stress perception. Therefore, it can be said that farm wives had relatively high economic stress perception in the case of low economic stability, getting into debt and low age.

The main purpose of this study was to find out variables relevant to self-care activities of physically disabled person. The subjects of this analysis were 1277 person which is between 15~64 years, the data came from the 1985 National Interview Survey on Disabled Person in Korea. For this analysis, Breakdown, Oneway and Discriminant Analysis were used. The finding of the analysis can be summarized as follows: First, the mean of self care activities was 2.57 (SD: 0.69, range: 1-3). The relevance for the self-care activities by several variables is as follows. 1. The relevance for the self-care activities by socioeconomic status is significant at age, education level, occupation of household members variables. Especially, in the case of high age, low education level, the self-care activities are shown low score. 2. The relevance by impairment characteristics is shown high significance at all input variables. When disabled person have double impairment. paralysis, late occurance age, and is due to diseases the self-care activities score is lowered. 3. The relevance by health care services variables. is not shown significant at all input variables. Second, the relevance for social activities by sev-eral variables was conducted by discriminant analysis. The relative importance of social activities discriminant function is 0.344 of eigenvalue. The-canonical correlation between the social activities discriminant function and 9 dummy variables is 0.51, total variance of dummy variables for social activities is shown 26 persent. The self-care activities variable represents the highest contribution of its associated variable to the function (canonical coefficient: -.56). The occurance age, the occupation of household members, the education level variables are shown comparatively high contribution to the function. To sum up, this analysis suggests that the self-care activities variable is the highest contributed to the social activities. In relation to self-care concept, this finding will be useful in rehabilitation nursing care.

A comprehensive air quality monitoring was carried out to investigate the criteria concentration of air pollutant in indoor of subway stations of Seoul City. The samples were collected twice per year (the first and the second half of the year) at each sampling point from February to September in 1997. Sampling point of subway stations was ticket office and platform. The measurement of indoor air pollutants such as sulfur dioxide(SO$_2$), nitrogen dioxide(NO$_2$), carbon monoxide(CO), carbon dioxide(CO$_2$), total suspended particulate(TSP) was performed to determine the indoor air quality. Heavy metals(Pb, Cd, Cu, Cr, As, Hg) were also measured together with those air pollutants. The annual average concentration of CO$_2$ and TSP in subway stations were relatively high while those of heavy metals were within 10% of environmental recommended standard concentration in all stations. As results of regression analysis between line and line of air factors, the concentrations of CO, CO$_2$, TSP, Pb, Cd, Cr and Cu were highly correlated, but those of $SO_2, NO_2$ and Hg were not correlated. As results of regression analysis between ticket office and platform, the concentrations of heavy metals such as Cr and Cu were highly correlated. Results of oneway analysis of variance between the first and the second half of the year air factors also indicated that CO, CO$_2$, Cd, Cu, Hg were significant($\alpha$=0.01), respectively. The average contration of total suspended particulate(TSP) in subway line No. 1 was shown high concentration(200 $\mu g/m^3\cdot$ day) level.

Objective : To characterize Five Woons of Asian women who live at Los Angeles area in U.S.A Methods : A set of physical tests and diagnostic questions were given to 242 Asian female subjects who were treated for their symptoms at a clinic of Asian medicine near Los Angeles in USA. The participants were given their constitutions, one of the Five Woons based on their birthdays. The physical tests included a body composition via Inbody 4.0 and an autonomic bioelectric response record via ABR2000. The oneway analysis of variance was applied to compare the means of the Five Woons and the physical test results. The Cross tabulation analysis was also applied to look for the effectiveness of Five Woons on the symptoms. Results : 1. In the body composition items, the LSD(least significant difference) showed that there were significant differences between the Soil Woon and the other Four Woons which are Water, Metal, Fire and Wood Woons in weight, fat, body fat %, BMI (p<0.2). 2. Based on the LSD, significant differences were observed among the Five Woons in R5, R6 and R7(p<0.2). 3. The cross tabulation analysis showed the significant effectiveness of the Five Woons on the five symptoms including dizziness, hot and cold, lower body edema, fatigue and to take a medication for high blood pressure out of 24 diagnostic questions (p<0.2). Conclusions : Further clinical research is necessary to develop a more delicate questionnaire and look for ways of characterizing the Five Woons. The diagnosis and corresponding treatment based on the Five Woons should be further studied in view of the Oriental medicine.

Recently, cosmetic shops play important roles in effectively delivering brand identity to customers. As a most effective mean to deliver brand identity to customers, a shop becomes the space to sell and buy brand image. This study divides brand identity into external identity as a space and internal identity as a brand philosophy with analysis of brand identity structure. To do this, the study proposition that brand awareness is high when there is high conformity between brand identities and survey to five Korean domestic cosmetic manufacturers that have a flagship store has been conducted to prove the proposition. With oneway Analysis of Variance on the survey, the result that the conformity between group's brand identities has significant relationship with brand awareness has been drawn. The findings are as followings; The spatial expression elements that have the strongest effects on the conformity between brand identities are facade, logo and sign, spatial image, fixtures image, symbolic sculpture and programs in order. For spatial elements, colors, shapes and materials have effects on conformity between brand identities in order. With analysis of spatial elements and their colors, shapes and materials, it is shown that all brand colors are used. In addition, brand conformity is emphasized with shapes and materials as well as colors. Futhermore, the brand awareness is improved when emphasis with such spatial elements is repeated in continuous manner. Also, the higher brand identity got, the higher brand awareness went up.

The purpose of this study is to identify the spatial characteristics of the parcels in which building construction occurred. In recent, urban development patterns in Korea have been shifting from the past. Small-scale development at parcel level is becoming more important in accordance with individual location needs in the low-growth era unlike public lead large-scale urban development in the rapid growth period. Therefore, it is necessary to study the spatial characteristics of the parcels where small-scale development takes place for future urban development management. This study used the chi square independence test, t-test and ANOVA (analysis of variance) to identify the spatial characteristics. The results of the study show that there is a spatial characteristics difference not only between building construction and non-building construction parcels, but also by type of building construction. The parcel where the building construction occurred have a higher proportion in detached house, major commercial districts, district unit planning areas, and commercial areas. In addition, it is caused by parcels, which are large scale and economically valuable, and are influenced by traffic factors such as urban centers and subway accessibility. As a result of each type of building construction, the parcels where the building use change occurred have spatial characteristic difference compared to other building construction, while the spatial characteristics are similar between the new construction/extension and new construction/extension with change of use. Based on this results, it will be possible to identify areas with high demand for small-scale development in the future and to utilize them for planning management of urban development. Furthermore, it will be possible to manage development demand by type of building construction, and to prepare differentiated plans considering the appropriateness of development plan, availability of infrastructure, and harmony with surrounding environment.
