This study examines the job satisfaction of cooks of school feeding. Sampling was taken among school feeding cooks except for those of Kangwon Province and Cheju Province. The factors affecting on the job satisfaction was investigated to find ways to raise the job satisfaction of cooks of school feeding. Four factors were extracted in all. It is found that these four factors have affected the job satisfaction of cooks of school feeding in order of working satisfaction factor(.493), co-worker communication factor(.463), job environment factor(.185), and advancement factor(.146). Accordingly, more opportunities for career advancement should be offered to raise the job satisfaction among them, and the establishment of better work environment and the optimum staff are urgently needed.

The purpose of this study was to develop satisfaction scale of school toilet that was completed repair work and examine its validity. In order to develop general and scientific satisfaction scale, the data was collected and analyzed targeting 3,694 participants from seventy schools which were elementary, middle, and high schools participating in improvement projects of school toilet in 2015 and 2016. Satisfaction scale of seventeen items was developed by using exploratory factor analysis and confirmatory factor analysis. Total Cronbach's ${\alpha}$ of seventeen items resulted in .950. Factor loading indicated over 0.6. Factor explanation of each item showed that was relatively high. This scale can be used to research unit school satisfaction and utilized for further research. The implication of this study was a reliable and valid instrument for measuring the satisfaction of school toilet.

In view of the effect of factor Ⅶ as a risk factor for essential hypertension, we investigated the length (I/D) polymorphism at position 323 promoter region and exon 8-Msp I RFLP of the human factor Ⅶ gene in the Korean patients with essential hypertension and normal controls. There were no significant differences in the allele, genotype and haplotype frequencies of these polymorphisms between normotensive and essential hypertensive subjects. The significant linkage disequilibrium was however, detected between two polymorphic sites. The Msp I RFLP and I/D polymorphism were also significantly associated with plasma triglyceride (TG) levels. Therefore, our results suggest that the significant association between two genetic variations in the human factor Ⅶ gene and plasma TG level may reflect the potential role of human factor Ⅶ gene as one of the genetic components for cardiovascular risk.

While screening proteins that interact with DnaA protein, the initiator protein for Escherichia coil chromosomal DNA replication, we found a 52-kD sized protein which bound to DnaA protein in a salt-dependent manner. This protein was identified as trigger factor, a ribosome-associated peptidyl-prolyl- cisltrans isomerase with chaperone activity. Trigger factor was overproduced and purified to near homogeneity, and its effect on the function of DnaA protein was examined, Enhanced binding of DnaA protein to DnaA box with no apparent supershift in the gel-shift experiments suggested that trigger factor, by virtue of its chaperone activity, exerts a change on DnaA protein thus increasing its binding affinity for DnaA box.

The purpose of this study is to offer fundamental data for classification of somatotype for boys of elementary school age. The subject were 458 elementary school boys aged from 7 to 12 living in Pusan, Data were collected by 57 anthropometric and 11 photographic measurements and analyzed by factor analysis according to SAS package 1. Through the factor analysis by each period of school ages 6-7 factor were obtained in upper half and they are as followings: 1) Factor 1 is horizontal size of upper half in every period 2) Factor 2 is vertical size of upper half in every period 3) Factor 3 is shoulder shape in the first period and length of upper half in the middle and latter period 4) Facto 4 sis length of upper half in the first period and shoulder shape in the middle and latter period 5) Factor 5 is angle shape of the breast and back in the first period angle shape of the lower breast and back in the middle of period and angle shape of the upper breast and back in the latter of period 6) Factor 6 is angle of shoulder in the first period angle shape of the upper breast and back in the middle of period and angle shape of the lower breast and back in the latter of period 7)Factor 7 is angle of shoulder in the latter of period 2. Through the factor analysis by each period of school ages 5-6 factor were obtained in lower half and they are as followings: 1) factor 1 is horizontal size of upper half in every period 2) Factor 2 is vertical size of upper half in every period 3) Pactor 3 is angle shape of the belly and upper buttock in the first period and length of lower half in the middle and latter period 5) Factor 5 is angle shape of the lower buttock in the first period angle shape of the upper belly and buttock in the middle of period and angle of the side posture in the latter of period 6) Factor 6 is angle shape of the lower buttock in the middle of period and angle shape of the lower belly and buttock

A simple graph G is said to be fractional n-factor-critical if after deleting any n vertices the remaining subgraph still has a fractional perfect matching. For fractional n-factor-criticality, in this paper, one necessary and sufficient condition, and three sufficient conditions related to maximum matching, complete closure are given.

In this study we use three-dimensional magnetohydrodynamic simulations of flux emergence from solar subsurface layer to corona. In order to study the twist parameter of magnetic field we compare the simulations for strongly twisted and weakly twisted cases. Based on the results, we derive a flux expansion factor of selected flux tubes which is a ratio of expanded cross section to the one measured at the footpoint of the flux tube. To understand the effect of flux expansion factor, we make a comparison between magnetic field configuration and the expansion factor. By using a fitting function of hyperbolic tangent we derive noticeable correlations among the strength of the vertical magnetic field, current density and expansion factor. We discuss what these results tell about the relationship between the twist of emerging field and the mechanism for the solar wind.

the purpose of this study was to consider the lower bodyshape factor of girls according to their age groups. The subject were 150 Korean Elementary School Girls and 150 Korean Junior High School Girls. The subjects were directly measured anthropometrically. In first group(Elementary School Girls) the result of factor analysis indicated that 7 factors were extracted through factor analysis and those factors comprise 83.1% of total variance and in second group (Junior High School Girls) 8 factors were extracted through factor analysis and those factors comprise 79.9% of total variance. Lower bodyshape factors were different to each groups. So these systematic information on typical bodyshape were provide to reduce the burden of stocks and increase clothing fitness.

This study investigated the degree of expectation and satisfaction with internship program of undergraduates majoring in culinary studies, and suggested improvements in satisfaction for training programs. Differences between expectation and satisfaction were significant in all 21 items including pay for internship program, rest spaces, and break time during working. Expectation questions were extracted to five factors. Factor 1 circumstances of kitchen Factor 2 staff's ability and attitude Factor 3 working environment Factor 4 working hours and pay and Factor 5 rotation, period, and placement of jobs. Five factors were also obtained from factor analysis of satisfaction. Factor 1 working hours and rest Factor 2 staff's attitude and pay Factor 3 facilities and sanitation Factor 4 circumstances of kitchen and Factor 5 period and placement of jobs. Overall satisfaction values showed significant differences depending on gender, school-year system, grade, age, and school. The working hours and rest factor had the most significant influence on the overall satisfaction with internship program of undergraduates majoring in culinary studies.

본 연구는 수학 교육의 가장 큰 이슈 중 하나인 수학에 관한 정의적 영역에서의 향상에 기여하고자 중 고등학교 학생들의 수학 불안에 영향을 미치는 배경 변인에 관한 연구를 실시하였다. 연구 결과 중학교 학생들은 고등학생들보다 더 높은 수학 불안을 나타냈는데, 특히 '외적 요인'과 '학습 방법 요인'에 따른 불안 수준이 높았다. 또한, 여학생보다는 남학생들에게 전반적으로 높은 수학 불안이 나타났으며, 두 집단의 학생들 모두 '외적 요인'과 '학습 방법 요인'에 따른 불안 수준이 더 높게 나타났다. 그 외에도 사교육 시간이 증가할수록 학생들의 수학 불안 수준은 증가하였으며, '시험 및 성적 요인'에서는 자기주도적 학습 시간이 낮은 집단이 나머지 두 집단에 비해 수학 불안의 수준이 높게 나타났다. 수학 불안검사의 4가지 하위 요인 중 학생들은 전반적으로, '시험 및 성적 요인'에 대한 불안이 가장 낮게 나타났고, '수학 외적 요인'에 대한 불안이 가장 높은 것으로 나타났다.
