This experiment was conducted to compare the influences of dietary sea urchin shell powder (SUSP) supplemented to broiler diets on performance, mineral contents and blood cholesterol for 5 weeks. The experimental diets contained 21.5 and $19\%$ CP for the starting and finishing period, respectively The ME was 3,100 kcal/kg of feed in both starter and finisher diets. One hundred sixty chicks were assigned to 4 treatments with 4 replicates and fed one of 4 experimental diets containing different levels of SUSP: 1) Control (commercial feed) 2) T1 (commercial feed with $1\%$ SUSP) 3) T2(commercial feed with $3\%$ SUSP) 4) T3(commercial feed with $5\%$ SUSP). Body weight gain was higher in the T1 group when fed the starter diet (P<0.05), but was the lowest in T1 group for finishing period. Feed efficiency was not significantly different between the control and treatment groups (P>0.05). The total cholesterol of the control was higher than the treatment groups and the HDL-cholesterol were higher in T2 and T3. However, effects of diets containing graded levels of SUSP on LDL-cholesterol and triglyceride contents were not found (P>0.05). The SUSP diets were increased significantly the Fe, Zn and Ca contents of chicken meat, and tended to increase total mineral contents. In conclusion, dietary supplementation of SUSP to broiler diets could be applied to the enhancement of Ca, Fe and total mineral contents levels in chicken meat.

This study was conducted to investigate the effect of curing additives on color property of smoked duck meat. Curing process of samples was performed one of the following treatments: C, non-curing: T1, 2.43% salt: T2, 2.43% salt + 0.49% tripolyphosphate (TPP): T3, 2.43% salt + 0.49% TPP + 0.002% nitrite: T4, 4.76% duck seasoning: and T5, 1.47% salt + 0.24% TPP + 0.2% L-ascorbic acid. Instrumental meat color of both breast and thigh of smoked duck showed that the CIE $a^*$ value of the T4 was significantly (p<0.05) higher than that of the other treatments, whereas T5 had a significantly (p<0.05) higher CIE $b^*$ value than the other treatments. In results of nitroso pigment, T5 of smoked duck breast was significantly (p<0.05) higher value compared to other treatments, whereas T3 and T5 of smoked duck thigh had a significantly (p<0.05) higher value than other treatments. Heme pigment contents of control and T5 was significantly (p<0.05) higher value compared to other treatments in smoked duck breast. Meat color of T3 by sensory evaluation showed redder (p<0.05) than other treatments. These results suggested that using L-ascorbic acid is revealed to be pink color without nitrite or pigment when manufacturing of smoked duck meat.

This study was conducted to measure the degree of Korean Gender Egalitarianism among the students from six different high schools(132 girls, 127 boys) in Sunchon si, Chunnam province from Dec. 7th to Dec. 15th in 1999. The survey on gender egalitarianism was done in relation to the public understanding of the subject matter, parents' hug times, and parent's communication skills. Korean gender egalitari- anism scale was standardized by Korea Woman Developmental Institutes in 1999. The data was analyzed by SAS program. Results were as follows: 1) Generally, girls are more conscious of gender egalitariannism than boys(t=-13.79, p<.001). Above all, the younger the students are, the more they feel equal(F=8.01, p<.01). In sibling cases, two sisters have the highest level of gender egalitarianism while two brothers have the lowest level of gender egalitarianism(F=9.20, p<.001). Students who come from religious families are more inclined to demonstrate gender equality(t= 2.42, p<.05). However, there is no difference in relation to the parents' ages or academic background or harmony within the family. 2) There is no difference that girls and boys generally communicate with their parents. In ages, 17 years old students communicate more than 18, 19 with parents(father F=3.97 p<.05ㆍmother F=5.31, p<.01). That is, the younger students can communicate with their mothers more often than the older ones. In sibling cases, two sisters have more openly communication to parents while two brothers have(F=2.84, p<.05). Students communicate with their parents regardless of parents' academic background. But those from the family in harmony have more open chance to communicate than those who are not in hamony(father F=21.66, p<.001ㆍmother F=13.37, p<.001). They can comm -unicate with their parents better when their fathers hug them than when they didn't get hugs(father t=-4.76, p<.001ㆍ mother t= -2.34, p<.05). They can also communicate with their patents better when their mothers hug them once or more than when they didn't get hugs(father t=-3.78, p<.001ㆍmother t=-5.64, p<.001). 3) There is no difference whether the father hugs or not, but the mother's hug is very important because students whose mothers hug them once or more have significantly more gender egalitarianism than those students whose mothers didn't do(t=-3.98, p<.001). Based upon these results, it is recommended that we reconsider the role of gender in the socialization of high school students and also include gender egalitarianism in sex education. In this context, further study should be done for the improvement of students' communication within the framework of egalitarianism based upon parents' hugs(semi-language). Continued study is especially important in regards to the mother's hug and its enhancement of the students' gender egalitarianism.

Purpose: This study aimed to investigate duty-related incidental stress, coping method, and stress factors in 133 new firefighters. Methods: A self-reported questionnaire was administrated to 133 new firefighters between April and May 2010. It consisted of 33 and 62 items concerning duty-related incident stress and coping methods, respectively. Data were analyzed by using the t-test, analysis of variance, Pearson correlation coefficient analysis, and multiple regression analysis. Results: New firefighters experienced the most stress when inappropriately dispatched. Duty-related incidental stress correlated with active (r = .420, p < .001) and passive coping (r = .450, p < .001). Also active coping statistically correlated with passive coping (r = .890, p < .001). Influencing factors of duty-related incidental stress were passive coping (t = 2.12, p < .05), experience of having a co-worker in a dangerous situation (t = 3.30, p < .001), having less than 6 months of work experience (t = 2.30, p < .05), and experience of having oneself in a dangerous situation (t = 2.05, p < .05). Conclusion: New firefighters need to be provided with training on active coping to prevent posttraumatic stress disorders and, social support immediately after an inappropriate and stressful dispatch.

SBR process used to evaluate the removal of organics, nitrogen and phosphorus on the basis of a report of research on a precedence at various operation cycle and condition change. Effluent concentration of COD were 50mg/l, 50mg/l, 90mg/l respectively, The removal rates of COD were nearly over 95% at Run 1, 2 and 4. But at Run 3, Effluent concentration of COD was 255.0mg/l, The removal rate of COD was 87% at Run 3. As Oxic/Anoxic rate was fixed and operating cycle of Oxic/Anoxic was changed, the removal rates of T-N were 74.7%, 46.9%, 28.5%, 63.3% respectively at Run 1~4. The case of Run 1 was best result. The removal rates of T-P was appeared in proportion to T-N removal rates and rest of $NO_2-N$. The removal rates of T-P were 51.2%, 35.5%, 41.5%, 51.9% respectively. The removal rates of COD, T-N, T-P were influenced on the change of SBR operation cycle. As organic loading rate was $1.43kgCOD/m^3day$ and C/N ratio was 3.0, operation cycle of Run 1 was best condition of T-N removal rates and T-P removal.

The cows manure has been used as fertilizers in farmland because of enough nutrients. However, excess nutrients can be washed off during a storm and affected on nearby waterbodies. In this paper, the runoff characteristics from farmland were studied to determine the watershed runoff rate. As results of estimating, watershed runoff rates with short-term runoff are BOD 0.6%, CODcr 0.3 %, CODMn 0.1 %, T-N 0.8 % and T-P 1.0 % On the other hand, they with long-term runoff are BOD 3.6 %, CODcr 1.0 %, CODMn 0.9 %, T-N 4.9 % and T-P 4.8 %. It is clean that the watershed runoff rates increase according to the rainfall runoff time.

This descriptive study was under taken to explore relationships among the quality of life, health locus of control and perceived state of health persons with cancer to contribute theoretical understanding about these phenomenon of interest to the quality of nursing care. The subjects of this were 200 persons with cancer (100- in patients and 100- out patients), both male and female, between 30 and 59 years of age. Data were obtained using a convenience sample technique from two university hospitals in seoul from August, 1989, to June, 1990. The instruments used for this study were the Quality of life scale developed by Ro, You - Ja and the Health Locus of Control scale developed by Wallston & Wallston. Data were analyzed using a SAS program for ANOVA, t-test, Schefffe test, Pearson Correlation Coefficients and Stepwise multiple regression. The results were as follows : 1. The scores on the quality of life scale ranged from 95 to 191 with as mean of 147.85(range 47 to 235). The Mean scores(range 1-5) on the different dimensions were family relationships 3.50, relationships with neighbours 3.48, self - esteem 3.17, physical state and function 2.99, economic life 2.93 and emotional life 2.91. 2. Significantly higher scores on the quality of life and demographic characteristics were as follows : the quality of life for women(t＝2.80, p＝ .006), for those without complications(t＝2.54, p＝ .013), and for those who perceived their illness as mild(F＝4.85, p＝ .009). Higher scores on quality of life were correlated with the following : 1) emotional state and the age group 50-59(F＝3.43, p＝ .34). 2) economic life and higher income(F＝6.72, p＝ .002), those without complications(t＝2.68, p＝ .00), and those who perceived their illness as mild(F＝3.11, p＝ .05). 3) self-esteem and marriage(F＝3.64, p＝.028), those without complications(t＝2.18, p＝.03), and those who perceived their illness as mild(F＝7.72, p＝.000). 4) physical state and funciton and the age group 30-39(F＝4.65, p＝.010), those without complications (t＝2.00, p＝.05), and those who perceived their illness as mild(F＝3.38, p＝.04). 5) family relationship and those who live with their spouse(t＝2.82, p＝.005). 3. There was a significant positive correlation between the subjects perceptions of their current state of health and the quality of life score(r＝.4364, p＝.0001). 4. There was no relationship between Locus of control and quality of life in this sample. 5. Stepwise multiple regression analysis showed that: 1) the perception of current health status was the main predictor and accounted for 20.11% of the total variance. 2) sex and educational level accounted for an additional 21.71% of the total variance. 6. The quality of life and the perception of their current health status of these patients with cancer were generally lower than those of healthy adults as noted in previous studies. In conclusion, the quality of life for these cancer patients was generally low especially in regard to their emotional state. The current perceived state of health, sex, complications and perceived degree of illness were important variables relatiog to quality of life.
