To determine whether rearing density affects the hypermelanosis on the blind side (ambicoloration) of olive flounders Paralichthys olivaceus, we reared fry with an unpigmented non-eyed (blind) side in duplicate at densities of 150 individuals/$m^2$ (commercial production density: control) and 450 individuals/$m^2$ (high density group) for 90 days in 1-t dark-green fiberglass reinforced plastics (FRP) tank. We recorded feed intake, feed conversion efficiency (FE), growth and survival, and measured the ratios of staining blind-side area (staining area) and ambicolored fish every 30 days. Daily feed intake (DFI), feed conversion efficiency (FE), growth rate, condition factors, and survival rate were calculated at the end of the experiment. Although the FE was higher in the high-density compared to the control, the two density groups showed similar feed intakes, growth, and survival. The ratio of staining area as well as the ratio of ambicolored fish significantly were significantly higher in the high-density group than in the control from days 30 to 60, but significantly increased and evened out by the end of the experiment (P<0.05). In conclusion, we determined that rearing density is not the main cause of the blind-side hypermelanosis, but found that increasing the rearing density can accelerate the ambicoloration in olive flounders.

This study analyzed home environment, self-efficacy and parents' child rearing attitudes of disruptive children and of cooperative children in the classroom. Participants were 322 children(11-12 years of age) and 49 teachers. Instruments were four kinds of questionnaires. Data were analyzed by T-test and Fisher's exact test. Results of between group differences in parents' academic backgrounds showed more parents of cooperative children had completed high school. Disruptive children's mothers were more occupied outside the home; cooperative children's mothers engaged in more housework at home. Disruptive children's perceptions of their economic status were lower than cooperative children's perceptions. Results of comparison of general self-efficacy, scholastic self-efficacy, and home environment showed that disruptive children were statistically lower than cooperative children on all sub-variables.

Objective: This study was aimed to examine the mediating effects of mother's marital conflict and satisfaction between father's child-rearing involvement and mother's warmth of parenting style, and the moderating effect of mother's depression and self-esteem. Methods: The analyses involved using cross-sectional weights from the 1,703 samples of the 5th Panel Study on Korean Children to classify them into high and low depression groups, and high and low self-esteem groups. Path analysis and multiple group comparison analysis were conducted, controlled by child sex, mother's age and highest education level, and household financial assets. Results: The results were as follows: First, mother's marital conflict and satisfaction had a mediating effect on the relationship between father's child-rearing involvement and mother's warmth of parenting style. Second, mother's depression and self-esteem levels had a moderating effect the relationship between father's child-rearing involvement and mother's warmth of parenting style. In particular, mother's depression level affected the path between marital conflict and warmth of parenting style, and mother's self-esteem level affected the path between marital satisfaction and warmth of parenting style. Conclusion: Father's child-rearing involvement and mother's psychological level affect mother's marital relations and parenting style. Also, father's parenting involvement and psychological support is needed for a mother to regulate mood disorders, including depression and any self-serving bias.

In this study, we evaluated the efficiency of chemical marking of black rockfish scales by immersion in oxytetracycline hydrochloride (OTC, 500 ppm), alizarin red S (AR, 250 ppm) and calcein (CARL, 250 ppm) diluted rearing water. Immersion treatment of chemicals had no effects on both mortality and growth of black rockfish. Marking sucess was 100% in all treatment durations (24, 48 and 72 hours) with three chemicals and marking quality was higher in 48 and 72 hours than 24 hours treatment. Marking retention rates at 24 weeks after treatment were 100% in OTC and CAL treated group, but marking quality was higher in CAL treated group (brilliant 92%, bright 8% and dim 0%) than in OTC treated group (brilliant 4%, bright 70% and dim 26%). AR treated group had lower marking retention rates and marking quality than OTC and CAL treated group. As a results, immersion treatment with OTC and CAL was effective in marking scales of black rockfish and practical in releasing program and other studies requires same rearing environment.

This paper describes the results of a survey aimed at characterizing smallholder pig production systems in northern Lao PDR. A total of 341 households from five Northern provinces were interviewed in the survey. Village meetings and individual interviews, using a semi-structured questionnaire, were used to collect information. Three main pig rearing systems, free-scavenging, semi-scavenging and confinement (enclosures and pens), were found in the survey areas. These systems were practiced differently by smallholders depending on the level of intensity of crop production, ethnicity and purpose of keeping pigs. The confinement system was mainly practiced by Lao-Tai and Tibeto-Burman groups, who mainly bought piglets and fattened these pigs for sale. In contrast, the Mon-Khmer and Hmong-Mien reared pigs in free-scavenging and semi-scavenging systems, and usually keep sows for piglet production. The main factors that affected the changes in rearing systems were found to be level of intensity of crop production, local regulations and outbreaks of disease. The main constraints found in smallholder systems were outbreaks of disease, high mortality of piglets and the slow growth rate of fattening pigs.

Purpose: The purpose of this study was to explore the experiences of Korean mothers in parenting children with Hunter's syndrome, an X linked recessive genetically inherited disease usually affecting boys. Methods: Data were collected from 14 mothers having children with Hunter's syndrome, through two focus group interviews and individual in-depth interviews. Qualitative data from the field notes and transcribed notes were analyzed using the grounded theory methodology developed by Strauss & Corbin (1998). Results: The core category about the process of rearing children with Hunter's syndrome was identified as "navigating in the maze". The process of rearing children with Hunter's syndrome passed through three phases; 'entering an unknown region', 'struggling to escape from the unknown region', 'settling down in the unknown region'. Conclusion: In this study "navigating in the maze", as the core category deeply showed joys and sorrows of mothers in the process of rearing their children with Hunter's syndrome. In this rearing process they gradually adjusted themselves to their given condition. Also they gained initiatively coping strategies to care for, and protect their children. Therefore health care providers can establish supportive programs in the clinical field to empower these mothers by reflecting their proactive coping strategies.

For the effective seedling production of the hard shelled mussel, Mytilus coruscus, this study assessed the effects of the dietary value of live food, density, water temperature and salinity on growth and survival rate of the larvae. The optimal survival rate and growth rate were examined under differing conditions of water temperature, salinity, and rearing density for 30 days. The three groups were provided different feeding organisms, such as Isochrysis galbana and Teleaulax suecica. The mixtures were provided at a rate of $5{\times}10^4cell\;mL^{-1}$. The best growth was observed in the group with conditions $21^{\circ}C$ water temperature ($16.2{\pm}9.1{\mu}m$), 33 psu of salinity ($16.82{\pm}3.9{\mu}m$), $2500individual\;m^{-2}$ ($17.2{\pm}5.9{\mu}m$), and fed with $5{\times}10^4cell\;mL^{-1}$ of I. galbana and T. suecica mixture ($16.0{\pm}7.3{\mu}m$). The highest survival rate was found in the group at conditions $18^{\circ}C$ water temperature (66.4%), 33 psu of salinity (24.4%), $2500individual\;m^{-2}$ (65.8%), and fed with $5{\times}10^4cell\;mL^{-1}$ of I. galbana and T. suecica mixture (58.8%). We therefore conclude that the suitable culture conditions for the stable production of hard shelled mussel artificial seedlings was at 18 to $21^{\circ}C$ of temperature, 30 to 33 psu of salinity, 2500 to $5000individual\;m^{-2}$ of rearing density, and feeding supplement of $5{\times}10^4cell\;mL^{-1}$ of I. galbana and T. suecica mixture under semi running water system.
