  • In ordo to investigate the professional job perception and job satisfaction of interns and residents and its related factors, the author conducted survey using self administered questionnaire for 2 months(August and September, 1996). The study subjects were 562 interns and residents who worked at one university hospital(tertiary hospital) and two general hospitals(secondary hospital) in Taegu, Korea. Among them, 297 (52.8%) responded completely. The results were as follows ; Respondents thought that people component was most important, science and status components were next among professional value scales which meant the desirable attitudes required to conduct professional works. But, the score of professional value scales was generally high and not affected by other variables in multiple linear regression analysis. They seemed to have very normative and ideal perceptions about professional values. The score of professionalism scales, which were attitudinal and behavioral traits about professional job, of high grade residents was significantly higher than that of interns and lower grade residents. The score of reference to professional organization and autonomy factor were increasing significantly as the grade increased. Working conditions and perception for socioeconomic status of doctors influenced the score of professionalism scale significantly. It seemed that professional socialization was made during the training periods of interns and residents. Most of respondents answered that current socioeconomic status of doctors were middle and high strata but they responded that the socioeconomic status of doctors would fall in the future. They seemed to have a pessimistic thought about doctor's status. Generally the respondents thought that they were satisfied with doctor job and fit to the job, but 51.9% answered that if possible they would get other jobs. It seemed to reflect their critical thinking on doctors' status. Perceptions about socioeconomic status of doctors, professional value and professionalism influenced job satisfaction significantly. The interns and residents had high sense of calling to doctors and thought that doctors were socially important job. Generally they were satisfied with their job. Interns and residents had normative thoughts about the trait which compentent doctors must have. During the training period, they seemed to have attitude and perception as a professional and to make professional socializations.

  • Objectives : This study was purposed to estimate prevalence of upper extremity musculoskeletal symptoms, level of occupational stress and their relationship among dental hygienists. Methods : This questionnaire study was performed during May to October 2010 with 317 dental hygienists worked in Busan and Gyeongsangnam-do recruited as study population. The occupational stress and upper extremity musculoskeletal symptoms were accessed using questionnaire of the Korean Occupational Stress Scale and musculoskeletal symptoms from the Korea Occupational Safety Health Agency. Data analysis was performed with the descriptive analysis, chi-square test, and multiple logistic regression analysis using SPSS(ver 19.0K)program. Results : The prevalence of upper extremity musculoskeletal symptoms and the level of occupational stress were 79.2% and $52.67{\pm}4.86$ in dental hygienists. By multiple logistic regression analysis, job insecurity(OR=2.86, 95% CI: 1.38-5.94 in stress high risk group; reference-stress low risk group) and organizational system(OR=3.32, 95% CI: 1.55-7.08 in stress high risk group; reference-stress low risk group) were associated with upper extremity musculoskeletal symptoms in dental hygienists. Conclusions : The overall prevalence of upper extremity musculoskeletal symptoms and level of occupational stress in dental hygienists were relatively high and some sub-scales of occupational stress were related with upper extremity musculoskeletal symptoms. Not only previously reported risk factors of musculoskeletal symptoms but also occupational stress should consider to prevent and improve upper extremity musculoskeletal symptoms in dental hygienists.

  • In ancient times, architectural design was seen as a critical task in building technologies. Specifically, form, dimension and structural design are of significant. These aspects are associated with each other and to be emerged as a whole. Designing plan dimension was deemed to be the core of design technology due to its close relationship with module system. Thus, its evolution as well as development process typically represents and reflects the spirits and contents of design technologies in ancient China. In China, the materials regarding ancient architectural technology include Yingzaofashi(營造法式) of Song Dynasty and Gongchengzuofazeli(工程做法則例) of Qing Dynasty. They show many aspects concerning materials, structure, scale system and building. In Yingzaofashi, although the length of objects are decided by 'cai(材)' and 'fen(分)', there are no regulations on length, width and height of a building. However, in the construction of ancient buildings, the above mentioned basic scales are very important in both design and construction. The present paper attempts to discuss the significance, namely, the design principles of length, with and height of ancient chinese architecture.

  • DEM (Digital Elevation Model) is a useful dataset which represents the earth surface. Beside many applications, production and frequent update of DEM is a costly task. Recently global satellite based DEMs are available which has huge potential for application. To check the accuracy, this study compares two global DEMs: AW3D30 (Advanced Land Observing Satellite World 3D 30m) and SRTM30 (Shuttle Radar Topography Mission Global 30m) with reference resampled LiDAR DEM 30m in a test area around Chuncheon, Korea. The comparison analysis was based on statistics of each DEM, their difference, profiles, slope, basin and stream orders. As a result, it is found that SRTM30 and AW3D30 were much similar but inconsistent in the test area compared to the LiDAR30 DEM. In addition, SRTM30 shows less difference with LiDAR30 compared to the AW3D30 DEM. But, DEMs should be very carefully examined for area which has temporal or season changes. For basin and stream analysis, global DEMs can be used only for regional scale analysis not local large scales.

  • We present an extensive study of the environment of galaxies with bars in the low-redshift Uni-verse, using a volume-limited sample of over 30,000 galaxies drawn from the Sloan Digital Sky Survey, with visually-determined morphological classifications and bar identifications. We use four different statistics to quantify the environment of our galaxies: the projected two-point cross-correlation function with respect to a spectroscopic sample of reference galaxies, the background-subtracted number count of galaxies in a deep photometric sample in the vicinity of our galaxies, the overdensity of the local environment estimated at ~3 Mpc scale from the three-dimensional reconstruction of the cosmic density field of the local Universe, and the membership of our galaxies in the SDSS galaxy groups to segregate central to satellite systems. We find a weak, but significant trend for early-type galaxies with a bar to be more strongly clustered on scales from a few 100 kpc to 1 Mpc, when compared to early-type galaxies without a bar. For late-type galaxies, we find less neighbours within ~50 kpc around the barred late-types when compared to the unbarred late-types. For late-type galaxies we also detect a decrease of the bar fraction for dark matter dominated systems, and finally we find no obvious correlation between the overdensity and the fraction of barred galaxies in our sample.

  • The purpose of this study was to investigate the relationship between wive's sex-role attitude and their marital satisfaction for understanding a part of marital relations. For this purpose, a questionnaire was constructed and administrated to 626 married women. the sex role attitude scale was a modified version of the sex-role attitude scale constructed by Osmond and Martin, and the marital satisfaction scale was developed basing upon the scales used by Terman and Hayes & Stinnett. The result of this study are summarized as follows; The majority of wives have relatively modem attitude toward their sex role in the extra familial roles. Wives have relatively modem attitude toward their sex role when the couples are younger, more educated, on a higher income level and working or a job (especially or a professional job). Wife's education level, husband's education level and family income make significant difference in their marital satisfaction specifically, a wife would be relatively more satisfied when she has more education and the family income level is higher. It is founded that wives sex role attitude has significant relationship with their marital satisfaction. A wife tends to be more satisfied when she has a traditional sex role attitude . A professional wife who has a traditional attitude shows most satisfaction and one who has a modern attitude and not having a job tends to be most dissatisfied with her marriage. It is also founded that a wife who has traditional attitude and received college education are above shows most satisfaction while the wife who has modern attitude and received high school education or below shows most dissatisfaction with their marriage lives.

  • This study is aimed at providing useful data which can be utilized for the design of their dress forms and enhancing the fitness of their apparels. To this end 330 pre-school children living in the capital area and aged from 4 to 6 were sampled to be subject to the measurement of their somatotypes. The results of this study can be summarized as follows ; 1 By the analysis of overlapped cross section diagram and silhouette diagram of each somatotype both had a common shape of lean-backed upper troso. 2. The type 1 showed less dimensions in most scales than type 2 while their shoulder were less developed. The type 2 showing more development in each element. 3. As a result of comparing the dress forms designed in reference with classified somatotypes and the commercial ones it was found that the former ones had the upper body part slanted slightly backwards and the belly part extruded forwards while the latter had a straight posture with large shoulder parts. After all the commercial dress forms were found not to reflect the actual somatotypes of Pre-School children's.

  • In this paper, the damage and failure behavior of triaxially braided textile composites was studied using progressive failure analysis. The analysis was performed at both micro and meso-scales through iterative cycles. Stress based failure criteria were used to define the failure states at both micro- and meso-scale models. The stress-strain curve under uniaxial tensile loading was drawn based on the load-displacement curve from the progressive failure analysis and compared to those by test and computational results from reference for verification. Then, the detailed failure initiation and propagation was studied using the verified model for both tensile and compression loading cases. The failure modes of each part of the model were assessed at different stages of failure. Effect of ply stacking and number of unit cells considered were then investigated using the resulting stress-strain curves and damage patterns. Finally, the effect of matrix plasticity was examined for the compressive failure behavior of the same model using elastic, elastic - perfectly plastic and multi-linear elastic-plastic matrix properties.
