Purpose: Although the number of cancer survivors is increasing because of early diagnosis and better treatment, they are worried about relapses and metastasis. This study examined the dietary safety management awareness, capacity, and behavior of cancer survivors. Methods: Data were collected from 233 cancer survivors in Daegu and Gyeongbuk areas using a self-administered 5-Likert questionnaire from March to May 2018. Frequency analysis, one-way analysis of variance, factor analysis, reliability analysis, and correlation analysis were analyzed using the SPSS. Results: The average score for each factor was as follows: importance of weight management (3.83), education requirement (3.79), unhealthy diet (reverse, 3.64), food safety anxiety (3.34), lack of awareness of over and malnutrition (reverse, 3.26), obsession (3.23), cooking capacity (3.16), health-function pursuit (3.04), balanced diet (2.93), and chronic disease anxiety (2.64). The average dietary safety competency factors were significantly lower among the male survivors, aged 60-80 years, lower economic condition, and less nutritional supplement intake. Female survivors comprised the highest proportion with high health management and cooking capacity, while men had the lowest of all the factors (p < 0.001). The group that was low in all three capacity factors had a significantly lower average score of difficulty in acquiring knowledge (reverse), lack of awareness of over- and malnutrition (reverse), importance of weight management, education requirement, knowledge, balanced diet, and health-functional pursuit compared to the other groups (p < 0.001). Conclusion: To effectively manage health, dietary safety management education should be differentiated and actively conducted according to sex, age, cancer diagnosis time, economic status, nutritional supplement intake, and the capacity cluster of cancer survivors.

This study was conducted to identify the recognition for nursing competency importance, nursing competency level, and their influencing factors of nurses in the long-term care hospitals. Participants were 243 nurses who were working in the 11 long-term care hospitals. Data were collected from August 25 to September 3, 2014. Data were analyzed using descriptive statistics, t-test, ANOVA, Pearson's correlation and multiple regression by SPSS 19.0. Mean scores of the recognition for nursing competency importance and nursing competency level were $4.21{\pm}0.48$ and $3.47{\pm}0.46$ respectively. Nursing competency level was significantly lower than the recognition for nursing competency importance. The variable influencing the recognition for nursing competency importance was the position(${\beta}=.19$). The variables influencing the nursing competency level were the recognition of nursing competency importance (${\beta}=.37$), age (${\beta}=.20$), current work experience (${\beta}=.13$), health status (${\beta}=.13$). The results suggest the need of developing measurement tool and nursing competency enhancement programs which can well reflect the characteristics of nursing competency required in the long-term care hospital.

The purpose of this study was to investigate the actual situation of nursing students' exposure to blood and body fluids, and their knowledge, awareness and performance of standard precautions in an attempt to offer basic data for education of nursing students concerning infection control. The participants of this study were 309 juniors and seniors enrolled in the nursing colleges in J province. Of the participants, 71.5% turned out to have experienced exposure to the blood and body fluids of patients. The mean score of the knowledge about standard precautions was $20.59{\pm}2.05$, whereas grade, infection control education were statistically significant. The average awareness of standard precautions scored $4.67{\pm}.36$, and age, no follow-up measures were statistically significant. The mean sore for the performance of standard precautions was $4.25{\pm}.70$, while exposure to blood and body fluids was found to be statistically significant. There was positive correlation between the participants' knowledge, awareness and performance. The awareness(${\beta}=.274$) of standard precautions only stood out significantly among the factors affecting the performance of standard precautions, accounting for 8.6% in the performance variance of standard precautions. The study found it necessary to develop the infection control program in diverse ways by complementing especially the areas which used to show low awareness and performance of standard precautions. It is thus suggested to intensify education for students about infection control prior to starting clinical training.

Essential metals have been known to interact with non-essential toxic metals in the aspects of absorption, transport and deposition in the body. Iron deficiency has been reported to increase lead and/or cadmium absorption. The relation between iron and lead has been understood well in children but not in adults. Two hundred seventy adults (118 males and 152 females) were recruited from 3 different residental areas (rural, coastal and urban) to investigate the effects of environmental lead exposure on body iron status. The subjects were interviewed for life-style and diet of the last 24 hours, and measured for blood lead and body iron. The lead concentration in the whole blood was determined by a flameless method using an atomic absorption spectrophotometry. The body iron was evaluated with values of hemoglobin, hematocrit, RBCs, serum total iron, unsaturated iron binding capacity, total iron binding capacity and ferritin. The mean concentration of blood lead in adult was $3.31{\mu}g/dL$. The concentration was higher in male ($3.97{\mu}g/dL$) than in female ($2.86{\mu}g/dL$). The blood lead was influenced by residental area, life-style, smoking and drinking, occupation and diet habit of subjects, but not by age. A positive correlation was observed between the blood lead level and the serum iron or ferritin. These results suggest that environmental lead exposure in Korean adult may not be higher than other developed and developing countries. It is further indicated that blood lead in adult could be influenced by life-style, and environmental and genetic factors but no inverse relation with body iron as shown in children.

The primary purpose of this research paper is to study the nutrition intake status of high school students and their physical growth and development. Further, it made an attempt to find and define nutritional problems and assist in their growth and development through proper nutritional management. One hundred students in both sexes, first year grade in senior high school were provided with questionnaires. For six days the respondents filled out the questionnaires. They were asked to keep record of what they ate each meal. Their nutritional intake were analyzed in accordance with what they ate. Findings, conducted on percentage, CR test, t test, and F test, were as follows: 1. For the living circumstance a) Average numbers of brother and sister in sampled family were four. b) Seventy to eighty percent of the students were brought up by mother's milk at their infants and approximately 40% of students were weaned at the age of 7 to 18 months. c) Fifty percent of the respondents revealed irregulity in their meal time. d) Monthly average expenditure for daily food reached $20{\sim}40%$ out of total income. e) The most favorite foods reflect as follows: The most favorite main dish is boiled rice and side dish beaf. Fruits. juice, milk, ice cream are more popular snack among whole students. 2. Nutrition survey a) Calory sad nutrients were found to be below the recommended level, especially in calcium, vitamins A, $B_2$ and C. b) The total calory intake were composed of 73% from carbohydrate, 14% from protein and 13% from fat in the case of boys. The girls were 65%, 14%, 21% respectively. c) Both boys and girls in their animal protein intake averaged about 33% out of total protein intake. d) Meat consumption of the majority respondents were proportionate in $10{\sim}20%$ in their total food consumption. 3. The result of statistical analysis were as follows: a) Statistical significant differences in the relationship between the calory intake and physical growth index were observed at the level of p<0.05. b) Statistical significant differences in the relationship between the protein intake and physical growth index were observed at the level of p<0.05. c) Statistical significant differences in the relationship between meal time and physical growth index were observed at the level of 0.02<0.05. d) No statistical significant differences in the relationship among calory, protein intake and school records as well as intelligence were found. The experiment indicated that there is a direct relationship between nutrition and the physical growth and development, whereas There seems to be an indirect relationship between nutrition and intelligence.

A survey was conducted from January 23 to 31 and February 14 to 18, 1981, in Whaseounggun, Kyunggj-do, to investigate the dietary and nutritionary status, and prevalence of parasitic infection of the fertile women, in an attempt to provide an integrative perspective on the rural family health programmes. The results are summarised as follows; The total number of fertile women, randomly selected, was 197 ; 21 women were in the latter half of pregnancy; 38 women, lactating, the remaning, non-pregnant. Average age of the subjects was 31.4 years; average number of children, 2.7; average number of abortion, 0.9; average family number in home, 5.5. The families had a mean income of \ 2,470,000 per fear. The majority, 83.8% of the families, were engaged in farming. 61.4% of the subjects had completed schooling 6 years or less. The mean energy intake of the lactating women was 73.4% of the recommended allowance, while that of non-pregnant and pregnant women reached 86.9 to 88.6% of the recommendation. In the average diet of the subjects, carbohydrates contribute 74.6 to 81.7% of the total energy intake; protein 11.3 to 11.9%; fat 7.0 to 13.9%. Protein intake of non-pregnant, pregnant, and lactating women met 72.6%, 60.8%, and 65.2% of allowance, respectively; and those proteins were mainly derived from vegetable sources. The subjects ingested less than one-half of the allowances for iron, calcium, vitamin A, and riboflabin ; in contrast, thiamin and ascorbic acid levels were adequate or fairly acceptable. There were significant correlations of meal balance and food diversity scores to the mean intake levels of protein, calcium, iron, vitamin A, thiamin, and riboflavin. Only 10% of the pregnant women and 11.4% of non-pregnant and lactating women reached the acceptable level of hemoglobin. Positive prevalence of parasitic infection was found among about one-third of the subjects, 30.3% of women. Hematologic findings had no significant correlation to parasitic infection.

Bronchoplastlc procedures including sleeve lobectomy were initially introduced for patients whose pulmonary function was insufficient to tolerate pneumonectomy In more recent years, sleeve lobectomy has evolved as an alternative to pneumonectomy in carefully selected cases of bronchogenic carcinoma, especially for centrally located lesions. Between 1992 and 1995, bronchoplastic procedures for bronchogenic carcinoma were performed in 15 patients and the majority of operative procedures were sleeve lobectomy (W: 12). All procedures were considered as complete and potentially curative. Mean age was 62.3 years (range 46 to 70 years) and there were 12 males and 3 females. Of 15 patiients, 7 underwent right upper sleeve, 2 underwent right lower sleeve, 5 underwent left upper sleeve, and 1 underwent right sleeve pneumonectomy. Postoperative staging was , stage I in 3, stage ll in 8, stage llla in 3 and stage lII in 1. The postoperative complications included anastomosis site obstruction due to granulation tissue in 1, local recurrence in 3, and wound infection in 1 There were 1 operative death due to sepsis and 2 late deaths. The three-year survival rate was 80%. The significant correlation was observed (r=0.11) between the predicted FEVI (1.851 L) and measured FEVI (1 762L). In conclusion, bronchoplastic procedure will have better prognosis than pneumonectomy in selected lung cancer patients because of preserving good function in remnant lung.

A laboratory experiment was conducted to determine the content of phenolics and flavonoids, antioxidant activity and antioxidant enzyme activity for the extracts from cowpea seed and sprouts. Plant length and weight of cowpea sprouts were significantly increased until 7 days after seeding. Total phenolics level [mg chlorogenic acid equivalents (CAE) $kg^{-1}$ DW] was highest in dry seed (DS) extracts of cowpea ($63.9mg\;kg^{-1}$), followed by imbibed seed (IS) ($56.8mg\;kg^{-1}$) and 1-day-old sprout (1DOS) extracts ($46.4mg\;kg^{-1}$), and significantly reduced with increase of sprout age (p < 0.05). The antioxidant activity of the methanol extracts from all the samples showed same tendency to the results of total phenolics level, and dose-dependently increased. DPPH (1,1-diphenyl-2-picryl hydrazyl radical) free radical scavenging activity was higher in DS (87.3%) and IS (41.2%) than in cowpea sprouts from 1DOS to 7DOS, ranging from 17.1 to 30.4%. Antioxidant enzymes, APX, POX, and POX activities were highest in 7DOS and lowest in DS. SOD activity showed much higher activity in sprouts and in seeds. Correlation coefficient between physiological-active substance and the activity was highest between APX and CAT activities ($r^2$= 0.9574). Especially, total phenolics content was more highly correlated with antioxidant or with antioxidant enzyme activities than was total flavonoid level.
