There are some cases in trouble with monitoring emergency patient by existing electrode sensor in measuring instrument in home and hospital etc. And there are problem to measure because of coming down electrode in emergency car or vessel of shaking and fat, humidity of patient. In this study, it has designed band-type for patient to put on the breast easily and go around anywhere freely putting band electrode on his body. Gold has used as electrode material in this electrocardiogram because of its excellent electronic resistance peculiarity and no trouble with skin. And it is able to monitor multi-body-signal by additional design of periphery temperature. There are good results of body signal transmission in the breast or the rib, and get a little body signal in abdomen. We get a result it is better case of gold than usual electrode on signal detection, and know usual electrode was disposable, but we have more correct result from gold electrode sensor, being semi-permanent ana. great contact ability even if movement.

The adoption of VoIP is continuously increasing in public institutions, private enterprises and households due to cheaper cost and various supplementary services. Also, it is expected to spread widely the use of VoIP in mobile environment through the increasing use of smartphone. With the growing concern over the incidents of VoIP service while the VoIP service has become increasingly. Especially eavesdropping, it is possible to invade user privacy and drain the secret of company. So, it is important to adopt the protocols for VoIP secure communication. VoIP security protocols are already adopted in public institutions, but it is not adopted in private enterprises and households. In addition, it is necessary to verify whether the VoIP security protocol could be adopted or not in mobile VoIP due to its limited computing power. This paper compared the VoIP security protocol under fixed network and mobile network through performance evaluation. Finally, we found that it is possible to adopt the VoIP security protocols in mobile network.

This study aims to investigate the primary teachers' perception of social emotional learning (SEL) in Malawi. To achieve this purpose, total 78 questionnaires were gathered from 9 primary schools in rural area. The data was analyzed with independent-samples t-test, correlation analysis, and multiple regression analysis. The results of this study are follows. First, the sub-factors of the Malawian primary teachers' perception of SEL shows that Comfort is 4.10, Commitment is 4.59, and Culture is 3.78. Second, there was a significant difference in the Malawian primary teachers' perception by age, years of teaching, and participation to in-service training about SEL among the individual characteristics. Third, the Malawian primary teachers' degree of implementation of SEL in school was 4.01, and there was a significant difference by years of teaching. Forth, among the sub-factors of teachers' perception of SEL, Comfort had a positive effect on the degree of implementation of SEL. This result implied that the reason why Malawian primary teachers had difficulty in implementing SEL in the school might be not a lack of individual competence but feel uncomfortable with implementation. Therefore, in order to implement SEL in the Malawi school, it is necessary to support teachers so they have confidence and comfort psychologically.

Three kinds of foods (strawberry jam, J; braised lotus root, B-LR; stir-fried anchovies, SF-A) containing fructooligosaccharide (FOS) or isomaltooligosaccharide (IMO) were prepared, and the changes of physical properties and sugar composition were compared with control (sample containing sucrose). For the samples contaning oligosaccharides, $a^*$ value increased, and $b^*$ value decreased after cooking. The sample with sucrose showed higher hardness than those with FOS or IMO. For sugar composition and stability of the oligosaccharides after cooking, the amount of IMO was almost remained in each food, however, that of FOS decreased from 47.2, 49.5, 48.9 to 20.5, 49.0 and 28.8%, for J, B-LR and SF-A, respectively. Based on the above results, softer cooked food could be prepared with oligosaccharide than sucrose, and when considering to functionalitiy, IMO is more suitable for general cooking at home than FOS.

Everyday hearing handicap caused by presbycusis ultimately reduces quality of life in older adults. The aim of this study was to explore effects of cognitive impairment on self-reported hearing handicap in older adults with early-stage presbycusis. We compared K-HHIE scores between 40 elderly subjects with mild cognitive impairment (MCI) and age- and hearing-threshold matched 40 cognitively normal elderly (CNE) subjects. The results are as follows: 1) The MCI group scored significantly higher than the CNE group on the social/situational and emotional sections, and in total. 2) The MCI group scored significantly higher than the CNE group on all four subscales, and the most significant group difference was on the first subscale relating to interpersonal relationships and social handicaps. 3) Both groups scored highest on the item 8 (problems hearing whispering sounds) and item 15 (problems hearing TV or radio sounds). Besides those two items, the MCI group also scored high on the item 21 (problems hearing in a restaurant), item 6 (problems hearing when attending a party), item 3 (avoiding groups of people), and item 20 (personal or social restrictions). Our findings suggest that, among older adults with early-stage presbycusis, older adults with cognitive impairment tend to report greater everyday hearing handicap than their peers with normal cognitive function. Especially, they show significant problems hearing in background noise or multi-talker situations, which cause social restrictions and social/emotional loneliness.

The purpose of this study was to identify the factors influencing the quality of sleep in breast cancer patients receiving chemotherapy in the outpatient settings. The data were collected from 203 patients with breast cancer receiving chemotherapy in the outpatient settings at one tertiary hospital in B City. Stress, fatigue and depression were negatively correlated with quality of sleep (r=-.369, p=.001; r=-.565, p=.001; r=-.526, p=.001, respectively). Fatigue(${\beta}=-.387$, p<.001) was one of the biggest impact factors on quality of sleep which explained 31.6% of the variance of the sleep quality, followed by the experience of sleep disturbances prior to the diagnosis of breast cancer(${\beta}=-.178$, p<.002) and depression(${\beta}=-.231$, p<.004). In total, all of the antecedent variables explained significantly 37.4% of the variance of the sleep quality. Thus, in order to improve the quality of sleep, integrative nursing interventions need to be developed to reduce fatigue and depression among them, including an proactive system to screen out the patients with the experience of sleep disturbances prior to the diagnosis with breast cancer and to provide adequate pharmacological and/or non-pharmacological sleep interventions prior to the chemotherapy.

Oegosan Onggi Village can be characterized by having industrial significance and cultural significance of Onggi. However Onggijang(Onggi maker) worked in poor conditions because the village was in the limited development district. Throughout the new millenium phenomenon of Well-being, the awareness of cultural values has been increased while local government designated Onggi as Local Intangible Cultural Heritage(ICH). In this condition, Ulsan metro city and Ulju county paid attention to Onggi Village as tourist attractions. First, they worked improving condition of village through Cultural Tourist Attraction Plan. Second, they extended their participation in Onggi Festival so the festival growed. Third, they designated Onggijang in Village as Local ICH. These activities were the effort in order to revitalize the village, however the cultural tourist attraction plan was solely centralized into tourist attractions. Thus, the work condition of Onggijang was not considered sufficiently so the work condition had become more inconvenient than the previous situation. In the case of Onggi festival, the outward development has been accomplished in accordance with the growth of festival scale and visitors, while the identity of festival had been weaken so the Onggijang barely attended the Onggi festival. The designation of ICH was also the unilateral decision, Onggijang had been in the conflict relationship between Onggijang concerning the craftsmanship and maintenance of the ICH. Local Government had power on their Intangible Cultural Heritage(ICH). Therefore we need to seek for role and functions as community on ICH.

Sleep apnea, a medical condition associated with a variety of complications, is generally monitored by standard sleep polysomnography, which is expensive and uncomfortable. To overcome these limitations, this study proposes an unconstrained wearable monitoring system with stretch-fiber sensors that integrate with the wearer's clothing. The system allows patients to undergo examinations in a familiar environment while minimizing the occurrence of skin allergies caused by adhesive tools. As smart clothing for adult males with sleep apnea, long-sleeved T-shirts embedding fibrous sensors were developed, enabling real-time monitoring of the patients' breathing rate, oxygen saturation, and airflow as sleep apnea diagnostic indicators. The gauge factor was measured as 20.3 in sample 4. The maximum breathing intake, measured during three large breaths, was 2048 ml. the oxygen saturation was measured before and during breath-holding. The oxygen saturation change was 69.45%, showing a minimum measurable oxygen saturation of 70%. After washing the garment, the gauge factor reduced only to 18.0, confirming the durability of the proposed system. The wearable sleep apnea monitoring smart clothes are readily available in the home and can measure three indicators of sleep apnea: respiration rate, breathing flow and oxygen saturation.
