A number of management issues can be used as drivers for change in order to improve animal welfare and nursing capacity of the hyperprolific sow. Group housing of sows during gestation is a recommended practice from the perspective of animal welfare. Related health issues include reproductive health and the locomotor system. It appears that management of pregnant sows in groups is challenging for a producer and considerable skill is required. We explored the benefits and challenges of group housing, including feeding issues. Increasing litter size requires additional attention to the mammary gland and its ability to provide sufficient nursing for the growing litter. We discuss the fundamentals of mammary development and the specific challenges related to the hyperprolific sow. We also address challenges with the farrowing environment. It appears that the old-fashioned farrowing crate is not only outdated in terms of welfare from the public's perspective, but also fails to provide the environment that the sow needs to support her physiology of farrowing, nursing, and maternal behaviour. Studies from our group and others indicate that providing the sow with a loose housing system adequate in space and nesting material, along with reasonable chance for isolation, can be considered as fundamental for successful farrowing of the hyperprolific sow. It has also been shown that management strategies, such as split suckling and cross fostering, are necessary to ensure proper colostrum intake for all piglets born alive in a large litter. We thus conclude that welfare and nursing capacity of the sow can be improved by management. However, current megatrends such as the climate change may change sow management and force the industry to rethink goals of breeding and, for instance, breeding for better resilience may need to be included as goals for the future.

Emission characteristics of gaseous odor compounds emitted from the charcoal manufacturing process were investigated, and evaluated the odor removal efficiency of odor control devices. It was found that the measured odor dilution ratio of emission gases ranged from 10,000 to 44,814, which exceed largely the emission standard in the stack. Methylmercaptan, trimethylamine, hydrogen sulfide, acetaldehyde were turned out as major odor compounds of the charcoal manufacturing process. It was revealed that the odor removal ratio of odor control devices were very low due to the its improper maintenance and wrong design.

This study examined the effects of family environmental variables and parent-child communication on the self-esteem of delinquent and non-delinquent juveniles. For this study, a questionnaire was administered to 117 non-delinquent juveniles living with their parents as high school students and 98 delinquent juveniles aged 15~18 who live in detention centers for adolescence. The data was analyzed using t-test, cross-tab, correlation, and hierarchical multiple regression analysis with SPSS /PC window program. Based on these results, the following conclusions were drawn. First, it was found that non-delinquent juveniles show a more open communication style with their parents than delinquent juveniles. Furthermore, a high level of parent-child communication was associated with high self-esteem in adolescents. Second, although physical environment such as family type or economic status influences an adolescents' self-esteem, the degree of positive parent-child communication style has a much greater effect on an adolescents' self-esteem. Finally, in terms of the effects of family environmental variables and parent-child communication style on self-esteem, parent-child communication style has a stronger effect on delinquent juveniles than non-delinquent juveniles. These results shows the importance of communication style between parent and child, especially for families with delinquent juveniles.

Objectives: The purpose of this study was to investigate factors influencing the health status and life satisfaction of elders in welfare facilities. Methods: The subjects of this study were selected randomly among those without cognitive impairment from free (140 persons) and charged (140 persons) welfare facilities in the Yeongnam area. Data was analyzed using t-test and stepwise multiple regression. Results: Health status and life satisfaction were 2.52 and 1.98, respectively, in the elders from free welfare facilities, and 2.67 and 2.08 respectively, in the elders from charged welfare facilities. In those from free facilities, life satisfaction and motivation for getting into the welfare facility were the influencing factors of health status. In those from charged facilities, life satisfaction, gender, motivation for getting into the welfare facility, limited service such as physiotherapy, age, and lack of staff and professionalism were the influence factors of health status. In those from free facilities, health status, relationship conflict with fellow elders, lack of staff and professionalism, insufficient facilities and inadequate environment, and indifference of sons and daughters were the influence factors of life satisfaction. In those from charged facilities, health status, education and age were the influence factors of life satisfaction. Conclusions: It was found that both health status and life satisfaction of elders in charged welfare facilities were higher than those in free welfare facilities.

Objectives: An epidemiological investigation was requested for a worker who developed COPD and IPF after long-term molding and firing at a domestic tile manufacturing site. We would like to share the results of the exposure assessment and the estimation of past work. Methods: The content of crystalline silica in four raw materials was analyzed, and the respirable fraction of crystalline silica and dust generated in the air from molding and firing workers and other processes were measured. The measurement and analysis method referred to the NIOSH method. Results: The crystalline silica content of the raw material was 24~47%. The concentration of crystalline silica in the molding and firing process workers and the surrounding area was at the level of the exposure standards set by the Ministry of Employment and Labor and ACGIH, and the respirable and total dust exposure levels were generally low. The crystalline silica concentration of the area samples measured to estimate past work was about twice as high as the exposure standard of the Ministry of Employment and Labor (0.05 mg/m3), and the exposure levels of respirable dust were also quite high at 0.903 and 1.332 mg/m3. Conclusions: It was confirmed that tile molding and firing workers are currently exposed to a fairly high level of crystalline silica, and a high level is also confirmed in area samples to estimate past work. In the past, it is judged that the level of exposure would have been much higher due to differences in production volume, working method, presence/absence of local ventilation facilities, and process layout. When working in such a working environment for a long time, respiratory diseases such as lung cancer, COPD, and IPF can occur.

The purpose of this study is to examine if there is any difference due to the general characteristics of middle school students who are beneficiaries of educational welfare services and a special quality of use about educational welfare services. Additionally, the examination has been performed to understand the relationship that exists between the satisfaction about educational welfare services, and adaptation to school life and self-respect of middle school students who are beneficiaries of educational welfare services. The results of the study showed meaningful higher scores by male students than female students only in the environmental adaptation area among lower areas in school life adaptation due to sex. Due to school year, third-year students showed meaningful high scores in school life adaptation. The satisfaction about programs in each area of educational welfare services of middle school students who are beneficiaries of educational welfare services showed a meaningful static relationship with school life adaptation. The inspection of the relationship between satisfaction about educational welfare services and 5 lower areas of school life adaptation showed statistically meaningful results in the order of adaptation to the teacher, adaptation to the environment and adaptation to the class, which are lower areas. The examination on the relationship between self-respect and adaptation to school life showed that self-respect has a static relationship with all lower areas of school life and overall school life adaptation. However, no meaningful relationship was shown between the satisfaction about educational welfare services and self-respect. Also, it was found that the factors of grade, self-respect, the number of service utilization have an effect on school life adaptation. This study has some limitations. But in this study, which is different from other studies which dealt with students who had used partial areas of educational welfare services, students who were using all 4 areas of educational welfare services were selected as subjects. In addition, this study is significant in that basic data has been offered for establishment of a policy on educational welfare services in middle schools in the future.
