This study evaluates the nutritional retention factors influencing beef based on different cuts and boiling. Two cuts (brisket and shin foreshank) were prepared from beef and used in this experiment. Boiling methods were applied to each cut. The fat content of the boiled shin foreshank cut (236.43%) exceeded that of the brisket cut (142.38%). The moisture content of the boiled brisket cut (47.68%) was lower than that of the shin foreshank cut (49.54%). The sodium content of the boiled shin foreshank cut (47.89%) exceeded that of the brisket cut (37.30%). The potassium content of the boiled brisket cut (41.90%) exceeded that of the shin foreshank cut (39.63%). The calcium content of the boiled brisket cut (48.43%) was lower than that off the shin foreshank cut (71.34%). The phosphorus content of the boiled brisket cut (58.09%) exceeded that of the shin foreshank cut (57.24%). The iron content of the boiled brisket cut (72.72%) was lower than that of the shin foreshank cut (87.29%). Nutritional retention factors represent output data on cooking methods with a yield (%) for each item.

본 연구는 간호사의 감성지능과 전문직 자아개념이 재직의도에 미치는 영향을 파악하기 위해 시도되었다. 자료수집은 B광역시 소재 종합병원 3곳에 근무하는 간호사 170명을 대상으로 하였다. 자료수집 기간은 2019년 5월 7일부터 5월 30일까지 구조화된 설문지를 이용하여 시행되었다. 수집된 자료는 SPSS/WIN 24.0 프로그램을 이용하여 분석하였으며 t-test, ANOVA, Pearson correlation coefficients 와 stepwise multiple regression analysis를 이용하였다. 본 연구결과, 대상자의 감성지능 정도는 4.82점(7점만점), 전문직 자아개념 정도는 2.61점(4점만점), 재직의도 정도는 5.47점(8점만점)이었다. 대상자의 재직의도는 감성지능, 전문직 자아개념과 모두 유의한 양의 상관관계가 있는 것으로 나타났다. 대상자의 재직의도에 영향을 미치는 요인으로는 전문직자아개념(β=.456, p<.001), 연령(β=-.228, p<.001), 휴가(β=.197, p=.002)순으로 나타났다. 이들 요인들에 의한 재직의도 설명력은 총 35.9%(F=32.60, p<.001)로 나타났다. 따라서, 본 연구결과를 바탕으로 재직의도를 감소시키기 위한 프로그램 개발이 필요할 것으로 사료된다.

In the reversed-phase chromatography, the retention time of sample was investigated based on the molecular structure of compound. Several descriptors that were related to retention factors were selected, and then the values of descriptors were calculated with several softwares. The effect of retention factor was measured with calculated values, and the results were obtained that each descriptors of molecular structure of compound have different effect on the retention factor. Therefore, the empirical equation for seven types of descriptors considered was obtained, and it has high values of correlation coefficient. Furthermore, the experimental data and calculated values have good agreement.

본 연구는 기혼 여성간호사를 대상으로 재직의도에 대한 직장-가정 갈등과 사회적 지지의 영향을 확인하기 위하여 시도되었다. 연구 대상자는 C시의 종합병원에 근무하는 기혼 여성 간호사 156명이며 자료수집은 2017년 9월 1일부터 15일까지 하였다. 자료는 SPSS 23.0을 이용하여 빈도, t-test, one-way ANOVA, 피어슨 상관계수, 다중회귀분석을 하였다. 연구결과 재직의도에 영향을 주는 요인은 시간갈등, 동료지지, 자녀수 한명 이상, 책임간호사, 상사지지 순이었으며 이들의 설명력은 37.3%로 나타났다(F=11.25, p<.001). 본 연구에서 시간갈등은 음의 영향을, 동료지지와 상사지지는 양의 영향을 재직의도에 미치는 것을 보여주었다. 이러한 결과는 재직의도를 높이는 새로운 전략개발에 도움이 될 것이다. 기혼 여성간호사의 재직의도에 영향을 미치는 다른 요인을 확인하기 위한 후속연구가 필요하다.

Purpose: This study was aimed to identify the relationships among job stress, nursing performance, and retention intention of clinical nurse. Methods: Data was collected at a hospitals located in Seoul, from October 19 to October 26 in 2010. Total subjects were 270. Data was analyzed by PASW 18.0 program. Results: Job stress of the subjects was 3.69(0.43). Nursing performance of the subjects was 3.69(0.45). Retention intention of the subjects was 3.21(0.78). Job stress and nursing performance were correlated positively (r=0.276, p<0.001). Nursing performance and retention intension were correlated positively (r=0.151, p=0.05). But job stress were correlated with nursing performance negatively (r=-0.127, p=0.05). Conclusion: According to increasing the nursing performance and decreasing the job stress, retention intension of clinical nurse is increased. We suggest a new study on mediation effect by nursing performance on retention intention and to predict factors on retention intension.

Objectives: The purpose of this study was to examine factors affecting the retention intention of clinical dental hygienists. Methods: A total of 190 clinical dental hygienists were recruited as participants. Data were collected from March to May, 2023 and then analyzed using t-test, ANOVA, Pearson's correlation coefficient, and multiple regression through PASW Statistics 26.0. Results: Mean scores for job crafting, job satisfaction, positive psychological capital and retention intention were 3.22, 3.46, 3.57 and 3.46 respectively. Retention intention showed a significant relationship with positive psychological capital (r=0.299), job crafting (r=0.214), and job satisfaction (r=0.649). The results of the multiple regression analysis indicated that job satisfaction was the strongest predictor of retention intention, explaining 24.1% of the total variance (F=4.550, p<0.001). Conclusions: Variables that can affect the retention intention of clinical dental hygienists were identified, with job satisfaction emerging as a significant factor affect retention intention.

This research studies the factors which influence the tensile strength of tire cords. Five yam samples are made by changing the spinning conditions and viscosity to get various physical properties. Different twisting methods are introduced and the yams are twisted under different processing conditions for each twisting process. With the experimental results, various analyses are performed to find the important factors in retaining strength after the twisting process. SEM and optical microscopic photographs are taken along with some measurements to assist the analysis.

A liquid chromatographic chiral stationary phase (CSP) based on (+)-(18-crown-6)-2,3,11,12-tetracarboxilic acid without extra free aminopropyl groups on silica surface has been demonstrated to be quite effective for the resolution of various $\beta$-amino acids. The retention factors ($k_1$) for the resolution of $\beta$-amino acids on the CSP were quite large and the large retention factors might be quite attractive along with the reasonable separation factors ($\alpha$) for preparative scale enantioselective chromatography. The large retention factors on the CSP were found to be reduced effectively by adding ammonium ion to mobile phase without sacrificing the chiral recognition efficiency of the CSP. Consequently, the CSP is also quite applicable for use in analytical enantioselective chromatography.

Purpose: This study was conducted to investigate the structural equation modeling of retention intention in nurses. Methods: A total of 210 nurses from three hospitals in B city, South Korea participated in this study. A structural equation model was constructed to verify the fitness of this model. Data were analyzed using SPSS 20.0 and AMOS 21.0 programs. Results: The hypothetical model appeared to fit the data. Three of the selected six hypotheses for the hypothetical model were statistically significant. The retention intention model showed significant direct effects for job crafting and job demands and indirect effects for relation oriented culture, which explained 28% of the variation in nurses' retention intention. Conclusion: We found that nurses' job crafting behavior and job demands had significant influences on retention intention and relation oriented culture which affected by the factors job crafting.

The purpose of this study is to examine the impact of relationship quality on customer value, customer satisfaction and relationship retention intention in the B2B transaction relationship. For the empirical study, we conducted a survey of the PCB corporation's client companies and used 110 surveys of them for analysis. The results of this study are summarized as follows : First, trust, relationship satisfaction, unity and performance as factors of relationship quality had significantly positive effect on relationship retention intention by the medium of customer satisfaction. Second, utilitarian value which is a parameter did not have significantly effect on customer satisfaction and relationship retention intention. Whereas, hedonic value which is influenced by relationship satisfaction, unity and performance had significantly positive effect on customer satisfaction and relationship retention intention. These results are not treated weightily in the preceding studies and managing the hedonic value in B2B transaction relationship is considered important to improve the customer satisfaction and relationship retention intention.
