Diphlorethohydroxycarmalol (DPHC) is a known to modulate the expression of extracellular matrix (ECM) components in 3T3-L1. However, the possible role of DPHC in integument stability during obesity induction is not clear yet. We evaluated the effects of DPHC on collagen or elastic fiber quantity in integument during obesity induction with high-fat diet. The dorsal back integument sections were stained with hematoxylin-eosin, Masson trichrome, and Verhoff-Van Gieson. The intensities of collagen fibers and elastin fibers were analyzed with ImageJ. The number of fibroblasts was counted at ${\times}1,000$ fields. The number of fibroblast was increased by obesity induction, but DPHC suppressed it in a concentration-dependent manner both in lean and obese mice. On the other hand, the intensities of collagen fibers were increased by DPHC treatment in obese mice groups but not in lean mice groups. The intensities of collagen fibers of obese mice were lower than that of the lean mice in 0% group. However, the number became similar between lean and obese mice by the treatment of DPHC. The intensity of elastic fibers was increased in the lean mice with the concentration of DPHC. In the obese mice group, there were increasing patterns but only significant at 10% DPHC group. The intensity of elastic fibers of obese mice was higher than lean mice in 0%, 1%, and 10% groups. Histologically epithelial cells and follicle cells which were diffused nuclear staining forms were increased by DPHC treatment. The results suggest that the activity of integument cells during obesity induction can be modulated by DPHC.

The purpose of this study is systematically to examine the changes that have taken place to the community spaces of apartment complexes in the national capital region of Korea. The methodology used in this study entails analyzing existing research and case studies carried out on this subject matter. Prior to these case studies, an existing study had been made of the chronological changes in policy, related laws and regulations in Korea since the 1960s. This case study presents the component ratio and systematized present situation of community spaces in twenty-two apartment complexes. An analysis of the researching process has revealed the following important factors related to the changes that have occurred in community spaces in apartment complexes. (1) Apartment complexes were originally developed in the 1960s to ease the housing shortage. Because the priority was to solve the housing shortage, community spaces were not widely considered or developed. (2) The standard of community spaces was established as mandatory by law in the 1970s, resulting in the emergence of various facilities that provided community spaces. (3) In the 1980s, various design competitions for apartment complexes were conducted as an attempt to improve residential environments. This process resulted in the development of new characteristic of subsidiary facilities. (4) During the period when housing problems were being addressed in the 1990s, the Community Service Center was added to the welfare facilities for residents. (5) Recently, during the 2000s, an improvement in residential environments has evolved due to the expansion of housing supply and economic growth. The quality of community spaces has therefore improved from the 1960s onward. This study revealed that policy and related laws regarding community space in Korea have been developing in a suitable direction and that the addition of various facilities to community spaces has improved the quality of living environments.

The purpose of this study was to develop prevention and educational programs for battered women. The first stage was to assess battered women's health status and health needs. The second stage was to develop prevention and educational programs to improve battered women's health. A survey research design was used to gather data from June-November 1999 by the counselor. Research sample was recruited from shelter and women's counseling centers in Seoul, Inchon, Chooncheon, Taejeon, and Jeoju. Trained counselors contacted 218 women, who agreed verbally to participate in the study. The researcher did a literature review and developed the tool used. We did ten pretests and three counselors checked the tool for content validity. The reliability and validity of the instrument were acceptable. The second stage of the research consisted of lay-professional groups discussing the abuse problems and possible solutions. Each group had five professionals (counsellor, nurse, minister, psychiatrist, social worker) and five women who have experienced battering from her husband in community. Result of the survey and two(lay persons and professionals) group discussions showed that victims need more assessment of physical, mental and spiritual needs. Victims were beaten more often during their pregnancies than at other times. Various kind of strategy were frequently utilized, but still the number of women abused and suicides committed increased. Both studies showed that the women experienced severe beating, that they felt powerless, that they need to understand that society abuser characteristics, that they lack a protection support system and that society lacks would an understanding of battered women. Based on the result of both studies, we developed model for prevention and education of battered women. This educational program will increase women s power to solve the abuse problems. The ultimate goal of the program is to develop a one-stop center to give wholistic approach care to women in abuse situations.

Purpose: The purpose of this study was investigate the relationships among perceived social support, instrumental support needs, and depression of healthy, community dwelling elderly women. Method: This study was designed to examine whether the perceived social support and instrumental support were correlated with depression in elderly women. Data were cross-sectional and community-dwelling elderly individuals. The subject was 98 elderly women recruited from Elderly Welfare Center and Community center for Elderly. The instruments for this study were Personal Resource Questionnaire-part II, Geriatric Depression Scale (Short Form), and Instrumental Support Activities Checklist. Data were gathered by means of structured personal interviews. The internal consistency of the instruments was relatively good. Result: The participants' perceived social support was moderately high and instrumental support needs was low. Depression was mild and moderate relatively. The correlation analysis showed that the perceived social support was negatively related to depression and negatively related with instrumental support needs. Conclusion: The findings suggested that more perceived social support, less their depressive symptom in elderly women. It also revealed that the age, marital status, and socioeconomic status of elderly women also are important indicator of the elderly depression. Therefore nursing assessment and the design of intervention that incorporate the determinants supported in this study, such as perceived social support of the elderly women are needed in adopting and maintain health promoting lifestyle for the mental health and effective functioning in later life in women.

Objective: This study aimed to determine the effect of intermittent feeding and cold water on performance and carcass traits in broiler chickens between 4 to 6 wk of age exposed to daily high temperature. Methods: Broilers were assigned to four treatment groups according to a 2×2 factorial design between 22 to 42 d of age (80 broilers per treatment, 4 replications). Broilers were divided into two main groups as feeding type (ad-libitum [AL] and intermittent [IF] for 6 h daily) and sub-groups as water temperature (normal [NW], 24.9℃ and cold [CW], 16.4℃). Heat treatment was applied between 11.00 to 17.00 h daily between 22 to 42 d of age. Results: Live weight at 6th wk was not affected by feeding type and water temperature, but the live weight was significantly higher in IF chickens at the 5th wk (p<0.05). Average weekly gain of IF broiler chickens were higher compared to AL group at 4, 5, and 6 wk of age (p< 0.05). Although feeding type did not affect feed intake in 4 and 5th wk, feed intake was higher in IF chickens at 6th wk (p<0.01). In addition, feeding type and water temperature did not affect feed conversion ratio and interactions were not significant (p>0.05). Water temperature had no significant effect on heart, liver, gizzard, and abdominal fat percentages (p>0.05). Conclusion: It is concluded that IF increased the average weekly gain in chickens reared under daily heat stress for 6 h between 22 to 42 d of age. IF in hot environmental conditions slightly increased performance without adversely affecting health, welfare, and physiological traits, whereas CW implementation had no significant effect on performance. It can also be said that IF suppresses a sudden increase in body temperature depending on age and live weight.

Objective: Combination of two stressors on alteration of mineral footprints in animals needs due attention to meet maximum production and welfare, particularly in grazing sheep. This study tested whether ewes (Ovis aries) exposed to water deprivation and thermal-humidity stressors had altered mineral footprints in their wool, serum, urine, and feces. Methods: Nine ewes (age = 3 years; mean body weight = 41±3.5 kg) were divided among a control group with free access to water, and treatment groups with water deprivation lasting either 2 h (2hWD) or 3 h (3hWD) after feeding. Using a 3×3 Latin square design, animals were assigned to treatment groups for three sampling periods of 21 days each (n = 9). Blood was collected by jugular venipuncture. Wool was collected at the end of periods 2 and 3. Metabolic crates designed with metal grated floors were used for urine and feces collection. We measured sodium (Na), magnesium (Mg), phosphorus (P), chloride (Cl), calcium (Ca), manganese (Mn), copper (Cu), iron (Fe), and zinc (Zn). Results: The wool mineral levels did not differ between the treatment groups, although K was marginally lower (p = 0.10) in the 2hWD group. The serum and urine mineral levels did not differ between the treatments (p>0.05). Fecal K was significantly lower in the 2hWD group than in the other groups (p≤0.05). Conclusion: In conclusion, water deprivation and thermal-humidity exposure altered the excretion of K, but not of other minerals, in the wool, urine, feces, or serum of ewes. Thus, no additional mineral supplementation is needed for water deprived ewes during thermalhumidity exposure.

Purpose: The purpose of this study is to present a plan to expand the employment of the elderly in Small business as one of the ways to solve the problem of the supply and demand of the company due to the aging population and the problem of the elderly poverty. Research design, data and methodology: The method of this study is a qualitative research method, and the researcher visited a small and medium-sized company directly and collected data by conducting an in-depth interview with a business owner. The interview period was conducted on a total of 15 business owners from November 5, 2013 to November 18, 2013. Results: First, the reason why companies hire the elderly is because they are suitable people, and the reason why they are not employed is because the elderly are not suitable. Second, it was found that the most recruiting paths continued to work after retirement. Third, the strengths of the elderly in their businesses were diligence, integrity, leadership, wisdom, warmth, and skill. Disadvantages the elderly in their businesses include wanting to be treated as an adult, poor productivity, poor accuracy, and health risks. Fourth, in case of hiring the elderly, they were considering convergence with young employees, and it was suggested that there are no difficulties in being an elderly because the companies hiring the elderly use the elderly according to the characteristics of the elderly. Fifth, It is realistic to actively utilize the employment system after retirement. Sixth, it was found that, unlike young people, it is not easy to recruit people on the Internet, so it is necessary to improve the system. Lastly, some industries clearly distinguished between the jobs of the elderly and the jobs of the young, but in many industries, it was desirable to create jobs for the elderly by harmonizing the main and secondary jobs. Conclusion: Ultimately, the work of the elderly in small and medium-sized enterprises should be reborn as a high-quality job that can solve the poverty of the elderly by working as a regular worker in the enterprise, rather than simply working for the elderly.

Objective: High $NH_3$ emissions from poultry houses are reported to have negative impacts on health, welfare and safety of birds and humans, and on the environment. Objective of the present study was to determine the effects of two litter amendments on the $NH_3$ levels in broiler closed houses under hot-humid conditions. Methods: Giving a completely randomize design, nine closed houses, each housed 32,500 birds on paddy husk litter, were randomly allocated into two treatment (Mizuho; a bacterial culture mix and Rydall OE; an enzymatic biocatalyst) and control groups. $NH_3$ levels were determined thrice a day (0600, 1200, and 1800 h), at three heights from the litter surface (30, 90, and 150 cm), at 20 predetermined locations of a house, from day 1 to 41. Results: Rydall significantly reduced the $NH_3$ level compared to control and Mizuho. $NH_3$ levels at 30 cm were significantly higher than that of 90 and 150 cm. The $NH_3$ levels at 30 cm height were higher than 25 ppm level from day 9, 11, and 13 in Mizuho, control, and Rydall groups, respectively to day 41. $NH_3$ levels at 150 cm height were higher than maximum threshold limit of 50 ppm for human exposure from day 12, 14, and 15 in Mizuho, control, and Rydall groups, respectively to day 33. Being significantly different among each other, the $NH_3$ level was highest and lowest at 0600 and 1800 h. Litter amendments had no significant effects on growth performance. Rydall significantly increased the litter N content on day 24. Conclusion: It was concluded that the $NH_3$ levels of closed house broiler production facilities under tropical condition are so high that both birds and workers are exposed to above recommended levels during many days of the growing period. Compared to microbial culture, the enzymatic biocatalyst was found to be more effective in reducing $NH_3$ level.
