The study attempted to analyze the experiences concerning professional identities of social workers working in hospice palliative care(HPC) multidisciplinary team by adopting ground theory method. The data were drawn from in-depth interviews with 11 social workers working in HPC teams for more than a year. As a result of the study, 166 concepts, 21 themes and 10 categories were presented. The core theme was identified as "growing up as a professional recognized by clients and other team members". The characteristics of social work and those of hospital setting systematic barriers and problems of the governmental support program worked as external conditions. The conflicts and confusions in social workers' professional identities were brought about as results of the conditions while successful team and the characteristics of individual setting promoted to get over the problems. The social workers experienced professional rewards and personal growth from hospice practices by utilizing diverse strategies. It was proposed that social workers should make efforts to be recognized as an essential profession in HPC multidisciplinary teams together with resolving the institutional problems such as regulations on qualifications of HPC social worker, professional education and governmental supports to improve work conditions.

I have researched in the field the religious and performance culture of Indonesia through the musical iconography of Borobudur. There are many kinds of musical instruments which belong to India or Indonesia, performers being either court or folk musicians. Contemporary south-east Asian Indonesia has a broad religious heritage. Most of the population is Muslim, but the culture and customs are rooted in Indian Ramayana. I discovered, for example, the same percussion instruments played on a person's knees. I also came across similar string instruments with long and elliptical resonance casks on the iconography of the Incense Burner and Byam temple stone pagoda of Beakje dynasty in Korea and in Borobudur in Indonesia. The two musical instruments can not be found in other countries, such as Silla, Koguryŏ, China or the silk road area, but only Indonesia or India. This suggests that Beakje Buddhism is from the southern regions rather than China. I also discovered the same dancing motion with the court performers on the iconography of Borobudur, and the same musical instrument and performance in the Gamelan in today's Indonesian performance. Despite a disjuncture between the people and their past, the Shailendra Buddhism is alive in people's life and culture in the present day. So we can discover some familiarities between Indonesia's Gamelan and the percussional performance in Korean Buddhist rituals.

In this paper, I want to compare the mantra of Korean Buddhism with the jumun(呪文) of Daesoonjinrihoe in rites and cultivation. Regarding the mantra of Buddhism there are some researches, but there are few studies with regard to the jumun of Daesoonjinrihoe. The mantra of Buddhism and jumun of Daesoonjinrihoe look similar in pronouncing Hangul characters, but the religious and historical context around these seems to be different. The mantra of Korean Buddhism is associated with the introduction and diffusion process of esoteric Buddhism. In the early period of Buddhism some mantras were allowed by Buddha and the mantras were certified as a educational teaching in the period of Early Buddhist schools. In Mahayana school, the dharani that was abstracted from the vast Mahayana scriptures was developed. As Mahayana Buddhism develops, esoteric Buddhism was born in India. Esoteric Buddhism was introduced into China and was imported into Korea in Silla dynasty. In Koryo dynasty various rituals of esoteric Buddhism flourished and Jineunjong(眞言宗) and Chongjijong(總持宗) school were formed. In Chosun dynasty Buddhism was suppressed by government and the esoteric school was discontinued. But in rituals and cultivation the mantra and dharani were flourished in the latter part of Chosun dynasty. In modern period several esoteric schools were formed and developed. In present context the mantra was recited by many people in Korea. Main mantras are 'Om mani padme hum', 'Dharani of Avalokitesvara(神妙章句大陀羅尼)', 'neungumju(楞嚴呪)', 'Gwangmyung mantra(光明眞言) etc. The jumun of Daesoonjinrihoe was started by Kang Jeungsan(姜甑山) who was believed to be a God by Daesoonjinrihoe believers. Jeungsan used several existed mantras in creating new heaven and earth and made new jumuns by himself and taught them to his followers. Cho Jungsan(趙鼎山) who succeeded to the doctrines has received the jumuns by Jeungsan. He selected the jumuns to recite and determined the method how to spell these. Park Hankyung(朴漢慶) who opened Daesoonjinrihoe succeeded the rituals and doctrines. Every day ritual of Daesoonjinrihoe is chanting the jumun and the cultivation and gongbu(工夫) is practiced through jumun. Important jumuns of Daesoonjinrihoe are Taeulju(太乙呪) and Kidoju(祈禱呪). In the aspects of ritual, the mantra of Buddhism and the jumun of Daesoonjinrihoe perform a similar function. The mantra of Buddhism has the context of the doctrines of Buddhism and the method of Buddhistic practicing but the jumun of Daesoonjinrihoe is related to Jeungsan's teaching and the doctrines of Daesoonjinrihoe. But it is same that the mantra and jumun are used in communicating or uniting with ultimate reality. So the mantra and jumun are important vehicles for homo religius to meet the sacred and unite with the sacred and is regarded as the sacred word by the faithful which has a lot of symbols and meanings.

Five commercially available edible sweeteners are used as diet products because they can replace sucrose. In studies on the effects on animals and the human body, stability has been proven by excreting-oriented studies with characteristics of animal cells, and accumulation in small amounts has been ignored. On the other hand, plants can absorb, degrade, and accumulate foreign substances, so the effect of degradability and accumulation potential can be studied using plants. Metabolic effects in plants of commercially available saccharin and acesulfame potassium (Ace K) were tested using germinated barley and bean sprouts. In germinated barley and bean sprouts, saccharin and ace K showed inhibitory effects on plant growth in all organs from low concentrations in leaves, stems and roots. In addition, it can be observed that the symptoms of death appear clearly over time, so it can be seen that they are accumulated in the body of the plant. As the accumulated amount increases, the toxic effect increases and the plant reaches a state where it is unable to metabolize, turning black from the tip of the leaf and reaching a state of death. In order to remove the accumulated artificial sweetener, recovery was attempted by culturing in distilled water, but it acts as a substance that is not degraded and dies without avoiding toxicity. Saccharin and ace K cannot be excreted from the cell. Its toxic effects are thought to be persistent, inhibiting growth and eventually leading to cell death.

This study was conducted to compare the nutritional properties of cookies made with Israeli carp Cyprinus carpio (C-IC) to those made without Israeli carp (control). The proximate composition of C-IC per 100 g was 4.1 g moisture, 9.7 g protein, 29.2 g lipid, 1.4 g ash, and 55.6 g carbohydrates. Moisture, protein and ash contents were significantly higher and the carbohydrate content was significantly lower (P<0.05) in C-IC than control, but there was no difference in lipid content (P>0.05). The total amino acid content of C-IC per 100 g was 9.46 g and the major amino acid was glutamic acid (2.49 g). The mineral contents of C-IC per 100 g were 216.6 mg calcium, 193.2 mg phosphorus, 170.9 mg potassium, and 18.2 mg magnesium, which were all significantly higher than the contents of the control (P<0.05). The major fatty acids of C-IC were 16:0, 18:1n-9, and 18:2n-6. The digestibility of C-IC in the small intestine was 51.3%, which was higher than the digestibility of the control. These results suggest that C-IC have better nutritional properties than the control.

Background: With its developed port and related industries, the concentration of fine dust is high in Busan compared to other cities in South Korea. Many studies have reported the health effects of fine dust, but there has been a lack of information regarding concentrations of volatile organic compounds among those who exposed to high levels of fine dust. Objectives: This study aimed to define an area with high concentrations of particulate matter and perform biomonitoring surveys among the residents of the area. Methods: Air quality data was collected and the mean level of each district in Busan was derived. We then defined the area with the highest concentrations of PM₁₀ as a target site. Urine samples were collected from the 400 participants and analyzed for VOCs metabolites - trans,trans-Muconic Acid (t,t-MA) and N-AcetylS-(benzyl)-L-cysteine (BMA). Interviews were conducted by trained investigators to examine demographic information. The levels of t,t-MA and BMA were compared with representative South Korean population data (Korean National Environmental Health Survey). The association of the VOC metabolites and fine dust were analyzed by general linear regression analysis. Results: The mean of PM₁₀ in the target site was 42.50 ㎍/m³ from 2018 to 2020. Among the 400 participants in the target site, 74.8% were female and the average age of the participants was 66 years. The geometric mean of t,t-MA was 71.15 ㎍/g creatinine and the BMA was 7.00 ㎍/g creatinine among the residents. The levels were higher than the geometric mean from the 4th KoNEHS. The levels of t,t-MA showed significance in BMI, smoking status, and household income. BMA showed significance in gender and age. Conclusions: Compared to the general population of South Korea, the target site's residents had higher biomonitoring levels. Based on this study, continuous screening for high risk areas, including the target site, and biomonitoring of the residents are required.

This study was conducted to optimize the size of olive flounder Paralichthys olivaceus (OF) as a material of sikhae and to investigate the quality characteristics. The results on the protease activity of OF meat, protein and ash contents of the bone, and yields and hardness of fish bone during fermentation time suggest that the suitable fish weight for sikhae was less than 250 g. The proximate compositions of the OF sikhae fermented under optimum condition (fermentation for 9 days at 15℃), were 73.0% moisture, 12.0% crude protein, 1.3% crude fat and 2.4% ash. The salinity, titration acidity and amino acid nitrogen contents per 100 g sikhae were 1.7 g, 2.46 g, and 311.3 mg, respectively. The lactic acid bacteria concentration in the sikhae were 8.84 log CFU/g, which were higher than those (5.78-6.62 log CFU/g) of 5 kind of commercial flounder sikhae. The functional properties, such as ACE inhibitory activity (69.0%), antioxidative activity (69.3%), α-glucosidase inhibitory activity (22.7%), xanthine oxidase inhibitory activity (88.2%), and nitrite scavenging activity (96.4%) of the sikhae were superior to those of 5 kind of commercial flounder sikhae.

This study analyzed the current status of care policies and senior citizen issues in Korea, which has entered a super-aging society, and attempted to suggest improvement measures for desirable convergence policies. The problems of the elderly in Korea have emerged as health problems, poverty problems, loss of roles, and care problems due to changes in the concept of family, values, and socioeconomic structure. In addition, poor seniors need jobs and employment policies, and healthy middle-class seniors need policy development to enable leisure activities and volunteer activities. In particular, it is necessary to establish policies to enable people to spend the rest of their lives in elderly care facilities and elderly care hospitals through community care policies. The super-aging society accounts for more than 20% of the total population among those aged 65 or older, and according to the National Statistical Office, it is expected to become a super-aging society by 2025. Elderly welfare policies must provide various programs and the needs and services of elderly care, and in the future, a super-aging society will need to secure a lot of financial resources and maintain a productive population to cover the financial resources. In other words, the human life cycle is from birth to death, and when the ratio of natural deaths of the elderly and infants born is appropriate, the society and the country can be seen as stable, vibrant, and healthy societies.
