A suitable packing material for biofiltration of monoaromatic solvent vapors was selected among various types of packing materials such as peat, bark chips, vermiculite, and Hydroballs. A previously isolated strain, Pseudomonas pseudoalcaligenes BTXO2, which could utilize toluene, m-and p-xylene as carbon and energy sources was used as a biofilter inoculum. Four glass biofilters (6 cm dia. x 60 cm) were individually packed with each of the packing materials and solvent vapors were passed through the columns. During three weeks of peat biofilter operation, average removal efficiencies of toluene, m-and p-xylene were 90.4%, 95.3%, and 82.1%, respectively. With the other packings, the efficiencies were in the range of 10.1 to 58.6％ which were significantly lower than those of the peat biofilter. The peat biofilter was continually operated for approximately nine months and the biofilter sustained its degradation activity during the operation period with minimal maintenance. At steady state, average removal rates of toluene, m- and p-xylene vapors were estimated as 14.2, 5.5, and 8.1 g m$\^$-3/ packing h$\^$-1/, respectively.

China's agriculture is changing now, especially in terms of cash farming. Orange farming is one of the main cash crops. This study is to identify the labor utilization of orange farming of farm households in China. The Results are as follows. First, farm size increasing is an essential measure to save labor. Big farm requires less than 20% of labor inputs than that of average size farm. Second, in the aspect of the employment labor, while male labor accounted for the 5% of total labor, female employment labor took up much more, which amounts to almost half of family labor. Third, the average wage of men is almost twice as much as that of women's wage, and it is sharply increasing. Fourth, Chinese farm households put more labor input than Korean farm households in orange production, which is due to the substitution of capital for labor.

This study was on low-income female earners, and focused on family life events, social support, and support from children which low-income female easers had experienced. It also examined how family life events, social support, and support from the children affected the level of life satisfaction of the low-income age in the Seoul metropolitan area. The analysis of the data showed the following results: 1. The low-income female roamers experienced finance and business strains more than other family life events. The significant family life events that affected their life satisfaction were intra-family strains, finance and business stains, and illness and family care stains. 2. The level of social support was average. The low-income female earners reported that their relatives had provided the largest amount of support among their social network; however, only support from their friends affected their life satisfaction. Emotional support was the common support type which low-income female easers had received. 3. The perceived level of support from children was high, and it was the most significant variable that affected the life satisfaction of the low-income female eamers.

Purpose: This study aimed to identify the levels of oxaliplatin-induced peripheral neuropathy (OXLIPN) and the quality of life (QOL) related to OXLIPN in patients with digestive system cancer. Methods: A total of 83 patients with chemotherapy-induced peripheral neuropathy (CIPN)-related symptoms participated in this study. Data were collected through self-reported questionnaire which were constructed to include general and clinical characteristics, EORTC QLQ-C30, Patient Neurotoxicity Questionnaire (PNQ), and EORTC QLQ-CIPN20. Results: The average scores of OXLIPN upper and lower extremity scale were 30.01 and 29.16, respectively. The average scores of PNQ sensory and motor scale were 2.11 and 1.70, respectively. The mean score of the QLQ-C30 global health status was 54.85, and the range of mean score of the functional and symptom subdomains was 34.85~73.29 and 17.67~53.54, respectively. The CIPN-related symptoms positively correlated with the global health status scale and all subdomains of functional scale, respectively and negatively correlated with fatigue, pain, dyspnea, insomnia, and financial problem subdomains of the symptom scale, respectively. Conclusion: Oncology nurses should pay attention and provide remedies for CIPN symptoms reported by their patients. Nursing interventions should be developed for patients with digestive system cancer to alleviate CIPN and enhance their QOL.

Purpose: Investigation of the quality of life (QoL), family support and associated variables in patients with Parkinson's disease. Methods: The data were collected from 102 patients registered in the neurology department of C University Hospital. QoL was assessed using the Parkinson's Disease Questionnaire (PDQ-39) and Family Support Scale. Modified Hoehn and Yahr (H & Y) stages were obtained from an interview and clinical examination by a neurologist. Collected data were analyzed using the SAS program. Results: The participants' PDQ-39 average score was 34.34. The scores were significantly higher for participants who were older, who had a job and who were over 2.5 on the H & Y stage. The average for Family support scores was 41.6. Participants who had a living spouse, religion and a job scored higher than those who did not. PDQ-39 score had a positive correlation with age, job, and H & Y stage. Family support and PDQ-39 score were also positively correlated. Conclusion: It is recommended a program involving family that improves family support and be developed and that it be varied according to different H & Y stages, in order to improve QoL.

Cornus controversa is a long-lived woody species mostly distributed in East Asia. Random amplified polymorphic DNA (RAPD) markers were used to investigate the genetic diversity and population structure of Korean populations of this species. A high level of genetic variation was found in seven populations of C. controversa. The mean genetic diversity (H) was 0.222 across populations, varying from 0.200 to 0.238. Eighty of the 93 loci (86.0%) showed detectable polymorphism in at least one population. Total genetic diversity values ($H_T$) varied between 0.192 and 0.231, giving an average overall polymorphic loci of 0.212. The interlocus variation of genetic diversity within populations ($H_S$) was high (0.167). Mean of genetic diversity in C. controversa was higher than average values for species with similar life history traits. The sexual reproduction, perennial habitat, and longevity are proposed as possible factors contributing to high genetic diversity. On a per locus basis, the proportion of total genetic variation due to differences among populations ($G_{ST}$) ranged from 0.169 to 0.278 with a mean of 0.216, indicating that about 21.6% of the total genetic variation was among populations. An indirect estimate of the number of migrants per generation (Nm=1.893) indicated that gene flow was extensive among Korean populations of C. controversa.

In a cDNA microarray experiment using Cy3 and Cy5 as labeling agents, particularly for the direct design, cDNAs from some genes incorporate one dye more efficiently than the other, which is referred to as the gene-specific dye bias. Dye-swaps, in which two dyes are switched on replicate arrays, are commonly used to control the gene-specific dye bias. We developed a simple procedure to extract the gene-specific dye bias information from a partial dye swap experiment. We detected gene-specific dye bias by identifying outliers in an X-Y plane, where the X axis represents the average log-ratio from two sets of dye swap pairs and the Y axis exhibits the average log ratio of four forward labeled arrays. We used this information for detecting differentially expressed genes, of which the additionally detected genes were validated by real-time RT-PCR.

Three hundred and fifty-two growing pigs were utilized in three growth trials to investigate the effects of crystalline amino acid supplementation on growing pigs' growth performance and feed consumption. In Exp. 1, diets were formulated on the basis of digestible amino acids. Utilization of rapeseed meal plus cottonseed meal (R + C) in diet supported similar average daily gain (ADG), feed/gain (F/G) and cost per gain (p > 0.05) to group of soybean meal (SBM). In Exp. 2, 14% CP diets containing equal amount of cottonseed meal and rapeseed meal were formulated with the addition of threonine and/or tryptophan. Supplementation with threonine improved ADG and F/G (p < 0.05). Supplementation with only tryptophan made no benefits for ADG of growing pigs. In Exp. 3, diets with different threonine level were formulated. Increasing dietary threonine to 0.54% improved (p < 0.05) ADG and F/G compared to 0.45% dietary threonine. Increase in dietary threonine did not improve ADG (p > 0.05) but decreased F/G (p < 0.05) because of a decrease in average daily feed intake. Pigs fed diet with dietary threonine/lysine ratio of 67.5% supported optimum growth performance.
