The recent surge in live streaming has also changed the market for classical performing arts. Now more than just recording live performances, content specific to live streaming platforms is being produced, and live streaming is emerging as a new alternative to promoting and enjoying classical performances. Therefore, this study empirically analyzed the effect of service quality factors of the classical live streaming performance on the viewer satisfaction and the purchase intention of the on-site performance over the data collected from 198 viewers. Results suggest that, among the service quality factors of the classic live streaming performance, video content, convenience, and price, except for real-time interaction, affected the viewer satisfaction, and viewer satisfaction in turn affected the purchase intention of the on-site performance. Thus the publicity effect of live streaming for classical performing arts seemed to be proved.

This study aims to examine the optimum blanching conditions as a pretreatment condition to improve the storage stability of Dolsan leaf mustard pickle. The effects of the blan- ching temperature and time were investigated at a temperature range of $80-100^{\circ}C$. Sampling was done for 1 month after a 5 days interval. The L value of the Dolsan leaf mustard was found to be the highest at $80^{\circ}C$. The cutting force increased as the blanching temperature increased. The tensile strength decreased at $95^{\circ}C$ and $100^{\circ}C$. In addition, the sensory evaluation scores were the best at $80^{\circ}C$. The storage stability was assessed at various blanching temperatures to increase the sinigrin content during storage. Liquid chromatography with photodiode array and tandem mass spectrometry (LC-PDA/MS/MS) analysis was conducted to identify and quantify the sinigrin content in the Dolsan leaf mustard. Sinigrin as an internal standard was co-injected into each sample solution. The sample was monitored by recording the ultraviolet absorbance at 228 nm and by electrospray ionization (ESI) positive ion mode in the m/z 50-1,500 range. Blanching the sample at $80^{\circ}C$ showed the highest sinigrin concentration during storage among various temperatures and the maximum concentration was 350 ppm at 15 days storage. Study on utilization of vegetable from food processing of leaf mustard and preservation conservation results suggest that blanching at $80^{\circ}C$ is expected to improve the palatability of the pickle.

Objective: This study was conducted to evaluate Raman spectroscopy technique as a noninvasive tool to predict meat quality traits on Braford longissimus thoracis et lumborum muscle. Methods: Thirty samples of muscle from Braford steers were analyzed by classical meat quality techniques and by Raman spectroscopy with 785 nm laser excitation. Water holding capacity (WHC), intramuscular fat content (IMF), cooking loss (CL), and texture profile analysis recording hardness, cohesiveness, and chewiness were determined, along with fiber diameter and sarcomere length by scanning electron microscopy. Warner-Bratzler shear force (WBSF) analysis was used to differentiate tender and tough meat groups. Results: Higher values of cohesiveness and CL, together with lower values of WHC, IMF, and shorter sarcomere were obtained for tender meat samples than for the tougher ones. Raman spectra analysis allows tender and tough sample differentiation. The correlation between the quality attributes predicted by Raman and the physical measurements resulted in values of R² = 0.69 for hardness and 0,58 for WBSF. Pearson's correlation coefficient of hardness (r = 0.84) and WBSF (r = 0.79) parameters with the phenylalanine Raman signal at 1,003 cm^-1, suggests that the content of this amino acid could explain the differences between samples. Conclusion: Raman spectroscopy with 785 nm laser excitation is a suitable and accurate technique to identify beef with different quality attributes.

This study was conducted to examine how Korean women mange energy metabolism during lactation. Eighteen women recruited were healthy, had normal pregnancies and were required to breast-feed their babies exclusively for at least 12wks. During the study period, all subjects were visited and interviewed five times : 3d, 9d, 4wk, 8wk, and 12wk lactation. Body composition variables were analyzed by a bioelectrical impedance method, energy intakes were assessed by using the inventory-weighing method, energy expenditure were determined by recording daily activities, and milk energy output was investigated from the amount of milk production and the gross energy content of milk. The subjects consumed less energy than current recommended allowance all over the study period, but compatible with fairly adequate lactational performance. They responded the additional energy stress of lactation by enhancing metabolic efficiency, increasing energy intakes, reduction physical activities and mobilizing body reserves. Another finding in this study was that the reduction in body fat-free mass may be the one way that women meet the energy demands of lactation like the reduction in body fat mass. The results from this study suggest that current recommended additional energy need during lactation, 2.09MJ/d(500kcal/d), is too high for healthy Korean women. Our data also indicate that the changes of body composition and energy balance at earlier postpartum are extremely different from those at later periods.

The purpose of this study was to investigate the middle-class housewives` experience of housing environment through their own cognitive expressions. Subjects were 18 housewives living in the apartments at Junggye-Dong, Seoul and Field survey method was used. Indepth interview technique with planned questionnaire was used. The contents of individual`s housing life history were recorded by means of a recording machine. Cognitive expressions of subjects ontheir experience of housing environment were analiyzed by Content Analysis. Subjects have respectively experienced various housing types. The housing experiences were classified by stimuli and respones. Stimuli were again classified by the factors and characteristics of housing environment, whereas responses were classified by types and directions. Negative experiences were more frequent than positive ones. Negative evaluations were appeared more frequently In such case as the existence of community facilities, interior structure, bathrooms, and heating systems. The positive emotional experiences appeared more frequently were the natural characteristic$ of outdoors. When all the contents were analyzed by housing types experienced, subjects negatively remembered community facilities in high-rise apartments, and positively outdoors in detached single houses including traditional houses, and negatively heating systems in low-rise apartments and tenement houses. These contents, especially positive and negative aspects of past experience. can be used as basic data to understand residents` reponses and to plan furture houses more desirable for them.

The purpose of this paper is to explore the role of the variation of songs by teachers in early childhood classrooms where songs play an important role in managing the daily activities for young children. Early childhood teachers have demonstrated a high degree of competency to transform and modify a variety of songs that fit into children's developmental levels. The use of such songs enable both teachers and young learners to fully enjoy such classroom activities and are an important means for establishing rapport. The data were collected from direct observation and video recording in three early childhood classrooms, as well as through interviews with the teachers, and through the researcher's journals. The results of the study revealed that the teachers exhibit a high degree of professionalism in creating variations of the kind of songs that children seem to enjoy, and thereby creating high levels of classroom enjoyment generally. This study also showed that using a good variety of songs in early childhood classroom can facilitate understanding of the content in the curriculum Finally, this study also suggests that the teachers' skills in designing variations of songs can make early childhood education classrooms culturally attractive and aesthetically more creative.

Purpose: The purpose of this study was to analyze the experiences of acute care hospital nurses' on spiritual care with focus group interviews. Methods: Data were collected from 24 nurses recruited from one acute-care hospital in a southern province of Korea. Six focus groups were assembled considering age and religion. All interviews were recorded and transcribed. Data were analyzed using qualitative content analysis. Results: Five categories with 14 sub-categories emerged: 1) ambiguous concept: confusing terms, an additional job; 2) assessment of spiritual care needs: looking for spiritual care needs, not recognizing spiritual care needs; 3) spiritual care practices: active spiritual care, passive spiritual care ; 4) outcomes of spiritual care: comfort of the recipient, comfort of the provider; and 5) barriers to spiritual care: fear of criticism from others, lack of education, lack of time, space constraints, and absence of a recording system. Conclusion: Participants perceived spiritual care as an uncertain concept. Some participants recognized it as a form of nursing care, and others did not. They practiced spiritual care in acute-care settings according to their personal perceptions of spiritual care. Therefore, in order to perform spiritual nursing in acute-care hospitals, it is a priority for nurses to recognize the concept of spiritual nursing accurately. It is also necessary to prepare a hospital environment suitable for the provision of spiritual care.
