Demonstration of the highly positive correlation between blood cholestrol levels and heart disease has made consumers wary of the fats in meat, milk and eggs. The egg, as perhaps the single largest common source of cholesterol, has been cited by many members of the medical and scientific world as a food contributing to heart disease. In light of decreasing per capita egg consumption and continuing dietary egg cholesterol controversy, many researchers have focused their efforts on egg nutrition. The results reported, however, are often contradictory. In spite of the disputable scientific evidence, the egg has been labelled (erroneously) as a highly cholesterogenic food. The objective of this presentation is to present a general picture of the problem and discuss our laboratory findings relevant to the problem. An isotope technique was utilized to incorporate $^{14}C$-cholesterol into egg yolk lipoproteins and study the metabolic fate of dietary ovo-cholesterol in rats. Two hundred and fifty micro-curies of 4-$^{14}C$-cholesterol, emulsified in corn oil, were orally administered to five Single Comb White Leghorn laying hens. Eggs were collected, hard-boiled, and the hot dried egg yolk powder (HEY) was prepared. Total radioactivity excreted via feces was determined. The rat groups fed egg yolk powder excreted more than 95% of the ingested ovo-cholesterol, whereas the rat chow group excreted only 47%. No difference was observed between HEY and CEY treatments. Therefore, an unknown lipid factor present in egg folk accelerates cholesterol turnover rate and excretion via feces.

The seasonal pattern and the annual magnitude of the internal (or biochemical) and plant-soil cycles of phophorus in adjacent three different herb plant populations-Helianthus tuberosus L., Artemisia princeps Pampan and Phalaris anundinacea L.-in an old field of the basin in the Mt. Geumoh were investigated. A lot of the phosphorus demand for the three populations was supplied by the withdrawal from below-ground organ in early growing period, by the absorption from soil in mid-growing period and by the withdrawal from stem in later growing period. But in the A. princeps and P. arundianacea populations, a great deal of phosphorus seemed to be absorbed prior to the first withdrawal. The annual amount of the phosphorus flowing throughthe internal cycle was about 59% of the total hosphorus flow on theorgan level in the H. tuberosus population, 41% in the A. princeps population and 32% in the P. arundinacea population, indicating that the tuber plant had the most developed internal cycle system. The annual amount of phosphorus which took part in the plant-soil cycle in the stand of the three populations was in the range of 4.49-5.65 gPm-2, corresponding to only 3-8% of the extractable phosphorus contained in the soil of 0-20 cm depth. The fact that the H. tuberosus population is higher in the extent fo internal cycle but smaller in the magnitude of plant-soil cycle and lower in the turnover rate of phsophorus than the other two populations suggests that the growth of H. tuberosus population may be less dependent on soil phosphorus availability than those of the other two populations.

Purpose: The purpose of this study was to investigate the relationship among nursing organizational culture, work performance, and workplace bullying of nurses, and to identify the factors that affect workplace bullying. Methods: The design of this study was descriptive research, and the data were collected from October 26 to November 5, 2018. The research participants were 210 nurses in six general hospitals in G province. The data were analyzed by descriptive statistics, a t-test, one-way ANOVA, Scheff? post-hoc test, Pearson's correlation coefficient, and a stepwise multiple regression using SPSS 22.0. Results: The workplace bullying type showed negative correlations with innovation-oriented culture, relation-oriented culture, and work performance. The workplace bullying consequence showed negative correlations with the innovation-oriented culture, relation-oriented culture, and work performance, and showed positive correlations with the workplace bullying type. The factors influencing the results of the workplace bullying consequence were workplace bullying type followed by relation-oriented culture, and unmarried status. Conclusion: Workplace bullying among nurses was related to the nursing organizational culture and work performance. Therefore, in order to reduce the turnover rate of nurses and to help them adapt well to the nursing organizational culture, a bullying prevention and intervention program is necessary.

Objectives: The purpose of the study was to investigate the regional distribution and working environment of clinical dental hygienists in Korea. Methods: From 2015 to October 2016, a questionnaire was completed by 5,708 participants and the data were analyzed. Results: The region with the largest increase in clinical dental hygienist employees compared to graduates is Seoul. More than 50.0% of clinical dental hygienists working for less than 1.8 million won in the payroll period of 4-6 years were working in the Gwangju Jeonnam, Jeonbuk, and Gangwon regions. In addition, incentives and bonuses were rarely provided by localities and agencies. Although 43.4% provided both parental leave and maternity leave. Conclusions: In order to solve the fundamental problem of inter-regional movement and employee turnover rate of clinical dental hygienists, as well as address the regional imbalance in labor supply and demand, efforts should be made for institutional improvement to strengthen management and implementation.

Objectives: This study investigated the factors influencing organizational socialization of new dental hygienists and provides basic data for successful organizational socialization. Methods: Data were collected using self-report questionnaires from 199 new dental hygienists of dental clinic and hospital between June and September 2018. Data analysis using SPSS 22.0 included Independent t-test, one way ANOVA, Scheffe post-hoc test, Pearson correlation coefficients, and multiple regression analysis. Results: The new dental hygienists' professional self-concept, interpersonal ability, and organizational socialization value were $3.27{\pm}0.50$, $3.55{\pm}0.45$, and $3.03{\pm}0.37$, respectively. There were significant positive correlations between professional self-concepts, interpersonal relations, and organizational socialization. A positive correlation was found between professional self-concept and interpersonal relations. Factors affecting organizational socialization of new dental hygienists included the strength of work, interpersonal relations, and professional self-concept. Professional self-concept was the most influential factor leading to 54.7% of the variance in organizational socialization. Conclusions: Therefore, to improve the organizational socialization of new dental hygienists and reduce the turnover rate, it is necessary to develop and implement programs promoting professional self-concept and interpersonal relations.

This research was carried out to investigate soil mictoarthropods fauna in Namsan and Kwangreung which were considered to receive different degreeds of environmental pressures. In basic environmental data, Namsan where under rather accelerated acidification by air contamination and acidic rain showed low pH, tardy decomposition and turnover rate. Population density of soil microarthropods was high in Kwangreung 17,169.8/\ulcorner\ulcorner(coniferous forests), 17,892.6/$\textrm{m}^2$(deciduous forests) than in Namsan, 12,143.8/$\textrm{m}^2$ (coniferous forests), 14,216$\textrm{m}^2$(deciduous forests). Biomass of soil microarthropods was 2,020.219mg/$\textrm{m}^2$ at coniferous forests and 4,270.172mg/$\textrm{m}^2$ at deciduous forests in Namsan, and 3,287.326mg/$\textrm{m}^2$ at coniferous forests and 4326.1mg/$\textrm{m}^2$ at deciduous forests in Kwangreung. Population density constantly showed high in spring, and seasonal fluctuations were correlated with seasonal precipitation. As far as vertical distribution is concerned, population density was concentrated in litter layer as 70% while 30% are in soil layer and also decreased with increasing depth.
