The purpose of this study is to examine pathways of factors that influence job satisfaction for full-time and part-time married female employees with children of 18 or under and to compare path coefficients for two groups. Simultaneously analyzing multiple populations, we found that the path model was appropriate for both groups with significant differences in path coefficients. Income, workplace size, husband's support for wife's work, and work-to-family conflict had direct effects on job satisfaction for both groups whereas health had a direct effect only among full-time workers. Family-to-work conflict had an indirect effect for both types of workers, while health had an indirect effect among full-time employees only, and income and having children under school age among part-time employees only. The results indicate that differentiated approaches to increase job satisfaction for full- and part-time employees are needed.

Radiologist image perceived by radiology students plays important role for them in establishing a positive Radiology professionalism as well as having a satisfaction on their job. Thus, this study was conducted to examine the image of Radiologist perceived by both radiology students. Q-methodology was used for this study. 110 Q statements were extracted from qualitative survey from 110 radiology students. The selected statements were reviewed and revised by experts and 33 Q samples were finally selected. Then, 30 radiology students were recruited for this study and were asked to arrange the statement cards on a 9 point scale, which shaped a normal distribution. The data were then analyzed by using PQ method program. As a result, two types of Radiologist's images were explored: 'professional technology type', 'safety of patient type' The results of this study will be helpful to provide the direction that we have to pursue regarding educational and political perspectives.

In this study the concepts on the elongation, compactness and equivalent ellipse of catchment plan-forms are applied to the real basins considering their theoretical frameworks. The catchment plan-forms and corresponding equivalent ellipses, obtained from GIS, are inspected on downstream directions. As a result the catchment plan-forms seem to be the population of the basin shapes which come from the random interaction between two conjectures on Hack's law being controversial recently. The ratio of the maximum and minimum inertia moments of the catchment plan-form Ri is more sensitive to evaluate the elongation of the basin shapes than the ratio of the main channel length and diameter of circle which has the same area as the catchment plan-form E. The catchment plan-forms compactness measures show distinct aspects according to their different definitions. These results are caused by the difficulties to quantification of the shapes and the composite consideration with more than two compactness measures and the fractal analysis are therefore required to recover them.

This research aims to examine the difference in participation motivation, participation experience and identity negotiation between generations of overseas Koreans in the National Sports Festival(NSF). The subjects for this study were 360 overseas Koreans who took part in the 100th NSF held in Seoul in 2019. The results are as follows; First, while the first generation participated in the NSF because of visiting family and maintaining Korean identity, the second generation took part in the event for self-realization. Second, the second generation had more negative experiences than the second generation during the NSF. Third, while the first generation negotiated more identity with origin, the second generation had more identity with settlement.

This study makes a systematic approach to Hack's law considering self-affinity and self-similarity of natural basins as well as the elongation of corresponding catchment-plan forms. Catchment-plan forms extracted from DEM appear to be the population come from the interactions of 2 hypotheses on Hack's law. It is judged that the elongation measures based on inertia moments are more intuitive than the ones based on main channel lengths. The exponent of Hack's law, h, seems to be similar to the result of Gray's study (1961). However Hurst exponent, H, being 0.96 imply that catchment-plan forms considered in this study have isotropic increasing properties with scale. From this point of view it is inferred that the shapes of the basins in this study would be more affected from self-similarity of main channel lengths than self-affinity of catchment-plan forms.

The purpose of this study was to general needs and identify the educational needs for teaching competency of home economics teachers. based on their perception on teaching competency revealed in Previous studies. Data were collected from 1,104 schools selected by stratified sampling. based on school district, ranking and size. The 616 items of survey materials were collected from 417 schools and the levels of importance and performance were measured on Likert scale with 7- and 5- points, respectively. The analysis reveled that the educational needs for improving teaching competency were high in the following three areas out of seven areas. 1) interfacing ability with the local community and diverse human resources. 2) ability managing space and materials for learning 3) ability diversifying lesson development and evaluation ability. In addition. diversifying and professionalizing present development program for home economics teachers made higher score than improving education program for home economics teachers. These two needs of teachers showed significant differences according to their educational experiences and foundation types of their schools.

The purpose of this study is to investigate the concept of composition of educational service quality through two integrated research methods of open questionnaires and focus group interviews for college students majoring in beauty. Participants in the study majored in beauty at 2-year and 4-year universities nationwide. The enrolled students were set as a population, and 250 people were adopted as a random sampling method and used for the survey. The series of results are as follows. First, as a result of inductive content analysis of open questionnaires, the educational service quality of beauty majors was derived into five areas: major knowledge, educational quality, professor-student intimacy, student needs reflection, usability, curriculum composition, environmental efficiency, educational equipment, and reputation. Second, as a result of the focus group interview, inductive content analysis was more reasonably pointed out and derived in depth. As a result of this study, it is believed that it can be used as basic data for the development of measurement tools for educational service quality of beauty majors.

The change to the data economy requires a new analysis beyond ordinary research in the management field. Data matching refers to a technique or processing method that combines data sets collected from different samples with the same population. In this study, statistical matching was performed using random hotdeck and Mahalanobis distance functions using 2020 Survey of Korea Venture Firms and 2020 Korea Innovation Survey datas. Among the variables used for statistical matching simulation, the industry and the number of workers were set to be completely consistent, and region, business power, listed market, and sales were set as common variables. Simulation verification was confirmed by mean test and kernel density. As a result of the analysis, it was confirmed that statistical matching was appropriate because there was a difference in the average test, but a similar pattern was shown in the kernel density. This result attempted to expand the spectrum of the research method by experimenting with a data matching research methodology that has not been sufficiently attempted in the management field, and suggests implications in terms of data utilization and diversity.

기후변화를 나타내는 연구 결과들은 기온이나 강수량을 대상으로 하여 두 기간 평균치의 비교, 5년 이동평균치의 圖示, 회귀분석 등의 방법들을 사용하여 발표되지만 대부분의 경우 밑바탕이 되는 모집단의 통계적 특성을 엄격히 검토하지 않는 정성적인 분석인 경우가 많다. 서울, 부산, 인천, 목포 등 4개 지점의 80년 동안의 연강수량과 연평균기온자료를 분석한 결과 기온은 정규분포를 나타내므로 전통적인 t-검정과 회귀분석을 적용할 수 있다. t-검정 결과 두 기간(1920 $sim$ 1949, 1961 ~ 1990)은 연평균기온에서 0.3$^{\circ}$C에서 $0.8^{\circ}$C의 의의있는 차이를 보였다. 최근 30년의 연평균기온자료를 회귀분석한 결과 1년에 $0.02^{\circ}$C의 증가경향을 나타내었다. 연강수량은 정적인 왜곡도를 보이므로 정규분포를 가정하는 母數的 통계분석을 적용해서는 안되며 비모수적 통계분석법을 적용해야 한다. 연강수량의 분석에는 t-검정에 상응하는 Mann-Whitney 검정을 적용해 본 결과 두 기간(1920 ~ 1949, 1961 ~ 1990)의 평균은 통계적으로 의의있는 차이가 없었다. 회귀분석에 상응하는 Mann's 검정과 이 연구에서 새로이 제안된 Median Slope Change Estimator를 적용해 본 결과 역시 통계적으로 의의있는 변화가 없었다. Median Slope Change Estimator는 비모수적 통계치로서 회귀분석의 기울기에 해당하는 연변화를 나타낼 수 있는데 분석하려는 자료의 정규분포성을 요구하지 않으며 異常點(outlier) 영향에 덜 민감하다는 장점이 있으므로 주목하여 연구할 만한 가치가 있다.^{\circ}$~40$^{\circ}$ 구간에서는 ${\sigma}_c$와 I$_{sa}$, 40$^{\circ}$~90$^{\circ}$ 구간에서는 ${\sigma}_c$와 I$_{sd}$가 각각 양호한 상관관계를 보여준다. 또한 상관비(K=${\sigma}_c$/I$_s$)는 약 13정도로서 일반적으로 적용되는 비, 24와 상당한 차이가 있다. 이러한 현상은 호상편마암의 구조적 및 역학적 이방성 특성으로 인한 결과라고 판단된다. 한편 맥암류에서 K가 약 23정도로서 일반적인 비 24에 상당히 접근한다. 따라서, 이방성 구조가 뚜렷한 암석에서 상관비 24는 항상 적용할 수는 없으며 일축압축강도시험과 병행 실시하여 적용하는 것이 바람직하다.다. 한편, 감작감염후 77일과 도전감염후 7일의 시점에 있어서 sRBC에 대한 면역능에 미치는 영향은 전자의 양상과 비슷하였는데 대조에 비하여 지연형 과민반응과 로제트 형성능이 현저하게 저하되었다. 이 시점에 있어서의 유충회수율은 대조가 10.5% 이었는데 비하여 8.3%이었다.e also compared for the cases of Kim et al, which again gives promising agreement.면적 306~453$\textrm{cm}^2$, 유색계의 경우 수당면적 340~453$\textrm{cm}^2$ 일 때 경제능력을 제대로 발휘할 수 있고 경제성이 있는 것으로 나타났다. 첨가구가 높은 경향이 있었다8.4%. 79.7% 그리고 80.2%였다.
