Policies regarding to soil quality of the United States, the United Kingdom, the Netherlands, Germany, and Demark were analyzed to suggest Korean policy for improving soil quality concept and it's implementation. All countries met four criteria: I) Soil quality levels of contaminants are indebt to concept of contaminant risk to recipients (human and ecosystem); ii) Any soil quality value can't be a magic number to determine whether a site is contaminated or not. To determine risk of sites, risk assessment of the sites should be followed; iii) Concentrations of contaminants of sites are not always significantly certain to risk of human and ecosystem of the sites; and iv) Soil quality levels are adopted based on land uses and plans. Considering our rooms to improve policies and analysis of the other country reports on their legislations about soil quality levels, our policy implementation could be approached from these directions: i) Our concept for soil quality levels needs to develop in scientific and rational. ii) Soil quality levels and risk assessment should be implemented as determining tools of site contamination in parallel, and iii) Soil quality levels depending on land uses and plans should be developed in debt with rational and scientific concept of risk. Increasing efficacy of Korea policy regarding the soil quality levels would be in dept to applying concepts of SCL (Soil Contamination Level) and SRL (Soil Regulatory Level) developed, implementing soil quality levels and risk assessment of contaminated sites in conjunction, and classifying three distinctions of land uses based on sensitiveness of recipients (human and ecosystem) to contaminants in soil in this research.

Purpose: The study aimed to examine the effects of aroma hand massage on state sanxiety, depression, quality of sleep, and blood pressure levels of palliative patients in hospice. Methods: This study was conducted using a nonequivalent control group with a pretest-posttest design. The participants were 48 palliative patients in hospice (experimental group: 24, control group: 24). The aroma hand massage was given to the experimental group once a day for 5 days. Data were collected between December 2017 to February 2018. Data were analyzed using SPSS 20.0 program with the chi-square test, Fisher's exact test, independent t-test, and repeated measurement analysis of variance(ANOVA). Results: There were significant differences in state anxiety levels (t=2.41, p=.020) and quality of sleep (F=14.29, p<.001). However, significant differences in the levels of depression (t=1.59, p=.119), systolic blood pressure (F=0.37, p=.695), and diastolic blood pressure (F=0.37, p=.695) were observed. The aroma hand massage was effective in improving the quality of sleep and state anxiety levels of palliative patients in a hospice. Conclusion: The aroma hand massage was effective in improving the quality of sleep and state anxiety in a hospice.

Resveratrol (RSV, 3,5,4'-trihydroxytrans-stilbene) protects sperm from cryo-induced damage in various animal and human species. In this study, we aimed to assess the effect of dog sperm cryoprotective extender containing RSV on the quality of post-thaw dog sperm. Sperm were collected from 4 Beagles and supplemented with different concentrations of RSV (0, 100, 200, and 400 µM). After thawing, apoptosis index, and reactive oxygen species (ROS) levels were assessed to determine post-thaw sperm quality. Dog sperm cryopreserved with 400 µM RSV showed significant improvement in post-thaw sperm quality with lower apoptosis index and ROS levels (p < 0.05). Our results showed that the supplementation of dog sperm cryoprotective extender with RSV at a concentration of 400 µM improved the post-thaw dog sperm quality in the term of sperm ROS production and apoptosis. In addition, we emphasize the necessity of testing the ROS levels and apoptosis index using flow cytometry to determine the quality of post-thaw semen.

The purpose of this study was to investigate the levels of hope and the influencing factors on the hope in the hemodialysis patients. The subjects of this study consisted 101 patients who had received hemodialysis In two hospitals affiliated with Catholic University from June to August, 2000. The instruments used for the study were the Hope scale by Miller(1998) and Quality of life scale, Self esteem scale and Social support scale. Cronbach's $\alpha$ of measurement tools used in the study were 0.93 for the hope, 0.96 for quality of life, 0.78 for self-esteem and 0.92 for the social support. The data were analyzed by mean, t-test, ANOVA. Scheffe test, Pearson correlation coefficients and Stepwise multiple regression using the SAS program. The results were as follows; 1. Out of a score of 164 the mean score of the hope was $107.3\pm16.7$. The mean quality of life score was 102.5 out of 160. The scores concerning social support turned out to have a mean of 67.8 out of 100. The levels concerning self-esteem and self respect had a mean of 25.1 out of 40. 2. There was a positive relation between the quality of life and social support. Furthermore, the hope level was proportional to factors such as quality of life and social support. 3. Social support accounted for $32\%$ of influential variable on the hope. If transportation way to the hospital and quality of life were added. the total predictors explained $45\%$. The results suggested that the hope levels of hemodialysis patients were influenced by their social support and quality of life. Therefore nurses are encouraged to elevate the levels of patients' hope by using the social support and quality of life in caring the patients receiving hemodyalysis.

It is one of the most critical steps identifying impaired waterbodies exactly in the selection of target water quality indicators for the management of Total Maximum Daily Loads (TMDLs). Excess ratio and excess level were applied and analyzed by the stream zone basis in order to evaluate water impairment for Nakdong, Geum, Youngsan and Seomjin rivers. Each river basin was divided into stream zones in the light of its watershed and waterbody characteristics. Selected water quality parameters discussed in this study were pH, DO, BOD, COD, SS, T-P, T-Coli and F-Coli. The excess ratios of the water quality parameters were used to discriminate water bodies that did not meet water quality standards. The excess levels were used to classify the degradation of water quality. The excess ratios and the excess levels to the water quality criteria of the medium influence areas were used for each stream zone. The results indicate that the excess ratios and the excess levels are varied on the stream zone in each river basin. Three parameters, pH, DO and SS, met water quality standards in all stream zones. The other five parameters indicated very high excess ratios in most waterbodies, and especially T-P and T-Coli revealed to be very high excess levels in some waterbodies. These parameters could be considered as major target indicators for the management of TMDLs.

The problem of brake judder is typically caused by quality defects in manufacturing. This quality problem, however, can't be controlled deterministically and requires analyses and designs considering uncertainties. This paper presents a method for dynamic analysis of a brake judder considering uncertainties. Firstly, quality defects, which come from the uncertainties, are determined by examination of symptoms of the brake judder quality problem. Effective quality defects are selected by investigation of process capability and comparison of sensitivity of each quality defects and noise levels of the effective quality defects are determined. Secondly, flexible multibody dynamic analysis and finite element analysis according to the proposed method are carried out. Finally, The analysis results are compared with the test results with noise levels of the effective quality defects.

Quality is distinguished from the other important management indicators, cost and profitability, by the features of its far longer history and of common concern to both manufacturer and customer. We may say from this that quality has a far more human aspect than either cost or profitability. We stress the importance of establishing “quality culture.” But we do not commonly use the terms of “cost culture” or “productivity culture.”In addition, we know from our experiences that improving quality by creative methods can lead to lower cost and higher productivity, although the converse is not necessarily true. In the Maslow's hierarchy of human needs, it is known that the character of human needs changes from extrinsic and material ones at lower levels to intrinsic and mental or spiritual ones at higher levels. We know from our experience that employee satisfaction is closely linked with quality, which is of more human nature and can further be deployed into the detailed elements of quality. The leaders and managers should positively display leadership and respond to the efforts of the subordinates. Without these managerial leadership and efforts, it is almost impossible to provide essential and true customer satisfaction. They are the indispensable elements for business excellence.

Objective: Paraoxonase 1 (PON1), a calcium-dependent serum enzyme, has been shown to be involved in lipid metabolism. In this study, we examined the putative correlation of the serum PON1 level of Hanwoo, Korean native cattle, with gender and meat quality grade. Methods: PON1 levels were estimated by determining the arylesterase and paraoxonase activities (AE and PO, respectively) in serum samples from Hanwoo individuals (n = 56). Serum PON1 levels were analyzed in different gender groups (female [n = 21], castrated male [n = 17], and male [n = 18]), and meat quality grades (${\geq}1$ [n = 23], 2 [n = 21], and 3 [n = 12]). Results: Serum PON1 levels were similar in female ($AE=120{\pm}55U/mL$, $PO=84{\pm}43mU/mL$) and castrated male ($123{\pm}44U/mL$, $PO=89{\pm}30mU/mL$), while male showed a significantly lower level ($AE=65{\pm}43U/mL$, $PO=44{\pm}34mU/mL$). Furthermore, analysis of serum PON1 levels in three different grades of meat quality showed similar levels in the grades ${\geq}1$ ($AE=118{\pm}49U/mL$, $PO=84{\pm}37mU/mL$) and 2 ($AE=116{\pm}54U/mL$, $PO=82{\pm}43mU/mL$), while the level was significantly lower in the grade 3 ($AE=58{\pm}35U/mL$, $PO=39{\pm}27mU/mL$) of lower meat quality. Conclusion: We discovered the gender-dependent differences in serum PON1 levels of Hanwoo and a positive association of the serum PON1 level with meat quality. Results in this study suggest that PON1 would be a useful serum marker for preliminary screening of Hanwoo individuals with high-quality meat and applicable for genetic improvement.

Purpose: The purpose of this study is to identify levels of quality of health-related life (EQ-5D) and its related factors among vulnerable elders receiving home visiting health care services in some rural areas. Methods: The subjects of this study were vulnerable elders aged 65 or higher receiving visiting health care benefits by a public health center in a county. Results: Levels of health-related EQ-5D were high when the subjects were males, their ADL and IADL were high. The EQ-5D of the vulnerable elders and social supports had a positive correlation, while their IADL and depression had a negative correlation with the EQ-5D. We can see that the EQ-5D related factors are variables that have significance influence on gender, subjective health status, BMI, IADL, depression levels, and social support. Conclusion: To improve the EQ-5D of the vulnerable elderly, it needs maintenance of independent IADL levels, social supporting systems using small meeting of the elderly in community. It is necessary to maintain independent IADL levels, enhance social supporting systems including small group gatherings for elders living alone by means of places like community halls, and develop specific intervention programs for the prevention and management of depressive elders.

This study was carried out to investigate effects of crude protein (CP) levels in total mixed rations (TMR) on growth performance and meat quality in growing Korean black goats. Thirty-six 6-month-old growing black male goats (initial body weight =17.95${\pm}$0.13 kg) were used. The goats were randomly divided into four treatments and 9 animals were allotted to each treatment. In terms of treatments, CP levels in TMR were 14, 16, 18, and 20% of dry matter (DM) and all diets were isocaloric (2.4 Mcal ME/kg DM). The experiment lasted for 20 weeks with a 15-day adaptation period. After the end of the trial, five goats from each treatment were slaughtered to measure carcass characteristics and meat quality. Average daily gain (ADG) significantly (p<0.05) increased as dietary CP levels increased, but the highest ADG was found on the 18% CP treatment. The higher CP levels in TMR significantly (p<0.05) decreased feed conversion ratio, but the lowest ratio was on the 18% CP treatment, suggesting a higher bioavailability of nutrients by balanced energy and protein levels on this treatment. There was no significant difference in dressing percentage among treatments, but there was a tendency for levels more than 16% CP in TMR to have a comparatively higher dressing percentage than the 14% treatment. The percentages of meat, fat and bone were not significantly influenced by dietary CP levels. Dietary CP levels did not influence chemical composition of goat meat. Furthermore, there was no significant difference among treatments in any of the sensory parameters except for tenderness. Tenderness was similar for 18 and 20% treatments, which were significantly (p<0.05) higher than the 14% treatment. The results from this study suggested that an adequate CP level in TMR for achieving optimal growth performance and meat quality of growing Korean black goats might be 18% of DM, and that dietary CP level above 18% seemed not to further increase growth performance and meat quality.
