Objectives : This study was performed to investigate the health status and social support among elderly living alone with restricted daily functions using the data of the "2014 the Korean Elderly Survey". Methods : Data on 2,407 elderly living alone were drawn and statistically examined using a t-test, an ANOVA, and a multiple regression analysis. Results : The study found that first, the elderly living alone with restricted daily functions comprised 22.1% of the total elderly living alone, and those who were older elderly, illiterate, with low-income, having poor nutrition management, and with a poor health status. Second, among the elderly living alone with restricted daily functions, there was a group with very little support from the family and only 14.0% were covered by long-term care insurance. Third, the life satisfaction of the elderly with restricted functions was lower than that of the non-restricted elderly, and was affected by income, health conditions, depression, access to senior welfare centers, and communication with others. Conclusions : The elderly living alone with restricted daily functions have serious health risks and social support, and hence they should be provided with more proactive support for life, health care and social care to live independently within their communities.

The studies of multi-hop wireless networks are active as the new communication media, which does not require any fixed communication infrastructure. One of application of the networks is local information distribution service, which is useful far daily activities in certain geographically restricted region or community within a radius of several kilometers. In this paper, MID-Net, which is the network enabling such distribution service, and effective information distribution algorithm MCMS are proposed. The behavior of the MID-Net is characterized by the waiting time function, three types of the functions are proposed in this paper.

Objective: Objective of the study was to reduce heat stress in Murrah buffaloes and maintain their milk production and other vital functions during heat stress. Methods: A total of 21 dyads of calf-mother Murrah buffalo were selected for the study and equally divided in 3 treatment groups. First treatment group was restricted calf contact (RCC), second treatment group was fence line calf contact (FCC) and third treatment groups fence line calf contact and heat stress protection (FCC-HSP [time-controlled fan-fogger system] in the shed). Present study was conducted from April to mid-September 2021. Results: Maximum temperature and temperature humidity index in FCC-HSP shed were significantly (p<0.05) lower than that in FCC and RCC shed. Higher (p<0.05) mean daily milk yield in both the treatment groups FCC (10.36±0.30) and FCC-HSP (10.97±0.31) than RCC (8.29±0.41) was recorded. Though no significant difference between FCC and FCC-HSP in daily milk yield but FCC-HSP yielded 600 gm more milk than FCC. Pulse rate (PR) and respiration rate (RR) were lowest in FCC-HSP followed by FCC and RCC, respectively. Cortisol and prolactin levels were lower (p<0.05) in FCC-HSP followed by FCC and RCC, respectively. Conclusion: Hence, FCC along with heat stress ameliorative measures helped the buffaloes to be free of stress and maintain milk yield during heat stress period of the year in tropical conditions.

A mutation in the promoter region of uncoupling protein 3 (UCF3), specifically the -55C longrightarrow T transition, may influence an individual's energy metabolism and body weight. The objective of this study was to investigate the effect of a weight reduction program on endocrine functions and body fat distribution, related to UCP3 promoter genotype. Ninety overweight pre-menopausal female subjects participated in the weight reduction program at Yonsei University Hospital, and were placed on a calorie-restricted diet (300 kcal less than their daily requirements) for 12 weeks. After 12 weeks, all subjects on the program lost approximately 5% of their initial body weights and had lower Body Mass Index (BMI) values. Among the 90 women, 56 had a normal (without mutation) UCP3 genotype, while 34 women had mutations in the promoter region of UCP3. Despite similar weight reductions in both groups, a significantly higher decrease in abdominal adipose tissue was observed in the normal UCP3 genotype group, compared to the group with mutations. In particular, there was a significant reduction of fat at the lumbar 1 (Ll) level in the without-mutation group. Serum levels of total cholesterol, apolipoprotein Al were significantly decreased in the without-mutation group, by 4.4% and 5.7% respectively. Serum levels of hormones were not significantly changed in both groups artier the intervention. However, in the group without the mutations, the leptin level significantly reduced by 23.4% (p<0.001). Serum free fatty acid (FFA) concentration was significantly increased in the group with mutation following the weight reduction program. On the other hand, FFA responses were shown similar increases in both groups. In conclusion, although no difference was found in the magnitude of weight reduction in both groups, there were significant differences in body fat distribution and in endocrine function between the groups.

Recently, we consist in the crucial juncture have to develope culture goods which is worth standing for our nation's endemism. In this vein, this study tried to reproduce and apply it to the present time by the consideration of various elements such as the kind, the use and the fabrication of sewing craft-works was beloved in women's quarter called Kyubang in the Chosun dynasty. With this, this study was designed to develope craft-works which can make an appeal to foreigners with the merits between contemporary factor and traditional factor. The findings of this study were as follows; First, since economic system in the Chosun dynasty was based on home handicrafts and self-sufficiency, it was a commonplace of the Chosun dynasty that home industry such as sewing, spinning and sericulture was thriving among all the women without social ladder. And also, since women of the day were governed by confucian tradition and moral obligation, they mainly have to live in women's quarter called Kyubang restricted to visitors. For the reasons, Wives of the time have no choice but to spend their time by sewing in the promotion of virtues for woman. In additions, they made an effort to pray for the longevity, the wealthy and the fertility of their family members. Second, the sewing instruments is necessary for women's sewing. And also, since sewing instruments was considerably scientific, efficient in those shape and structure, this instruments could save wives a lot of trouble. Third, since many people were convinced of the functions as practicality as well as fanciness, the sewing craft-works were very useful to them in leading their daily life. Fourth, the reappeared works were a total of 22, and the applied works were a total of 17.

Background: Cultivation of medicinal crops, which synthesize hundreds of substances for curative functions, was focused on the synthesis of secondary metabolites rather than biomass accumulation. Nutrition is an important restrict factor for plant growth and secondary metabolites, but little attention has been given to the plasticity of nutrient uptake and secondary metabolites synthesis response to soil nitrogen (N) change. Methods: Two year-field experiments of Sanqi (Panax notoginseng), which can synthesize a high level of saponin in cells, were conducted to study the effects of N application on the temporal dynamics of biomass, nutrient absorption, root architecture and the relationships between these parameters and saponin synthesis. Results: Increasing N fertilizer rates could improve the dry matter yields and nutrient absorption ability through increasing the maximum daily growth (or nutrient uptake) rate. Under suitable N level (225 kg/ha N), Sanqi restricted the root length and surface and enhanced the root diameter and N uptake rate per root length (NURI) to promote nutrient absorption, but the opposite status of Sanqi root architecture and NURI was found when soil N was deficient. Furthermore, increasing N rates could promote the accumulation of saponin in roots through improving the NURI, which showed a significant positive relationship with the content of saponin in the taproots. Conclusion: Appropriate N fertilizer rates could optimize both root architecture and nutrient uptake efficiency, then promote both the accumulation of dry matter and the synthesis of saponins.
