This study was conducted to optimize the level of sugar added (20 (control), 15, 10, 5%) during the preparation of soy sauce-salted mushrooms (Pleurotus eryngii) jangachi without affecting the degree of preference. The salinity and sugar content during storage of soy sauce-salted mushrooms (Pleurotus eryngii) jangachi decreased significantly as the level of sugar added decreased. The moisture content was found to increase as the level of sugar added decreased. Additionally, the pH increased, while hardness decreased as the level of sugar added decreased during 3 weeks of storage. The L value (lightness) was not different from that of the control group until the addition of 10% sugar, while the a value (redness) and b value (yellowness) increased. The antioxidant activity of vitamin C content and DPPH radical scavenging activity increased as sugar content decreased. Upon sensory evaluation of mushrooms (Pleurotus eryngii) jangachi, the highest value in appearance was observed for the 5 and 15% treatments, while 5% had the highest flavor value, 15 and 10% had the highest taste values, 10 and 15% had the highest texture values, the control and 5% had the greatest clarification values, and the 15 and 10% groups had the greatest overall acceptance. These results suggest that a sugar level of 15% can be used without significantly affecting the overall acceptance.

This study examines the service satisfaction rate on high school students(637) in order to provide the basic data for marketing direction by analyzing the importance and satisfaction rate of the service quality. In IPA for the service quality, as the following properties are high in expectation as well as satisfaction they needed to maintain. They are the taste, scent, saltiness, proper temperature of the food, the quantity main food, nutritional value, the degree of freshness, and the smell of dining room. The following properties need the excessive efforts. They are the number of side dishes, eating place, the shape and material quality of dish, the costume of dining workers. As the following showed low importance degrees as well as satisfaction degrees, they don't need concentrated efforts. They are the harmony of color and shape, the interior design of the dining room, the arrangement of tables and chairs, the atmosphere of dining room, and the effect of nutrition instruction. As the education of nutrition is compulsory among the school group meal, the analysis based on the response of questioned students is supposed to be more careful. The items showing low satisfaction degrees while high importance degrees are considered to make an operational plans for the improvement through a variety of menu, the quality of food, the quantity for side-dishes, health control, the cleanness of dishes, the kindness of cooks, the performance of nutritionists, the charge of school meal, and meal time.

The SinGAN is one of generative adversarial networks that can be trained on a single nature image. It has poor ability to learn more global features from nature image, and losses much local detail information when it generates arbitrary size image sample. To solve the problem, a non-linear function is firstly proposed to control downsampling ratio that is ratio between the size of current image and the size of next downsampled image, to increase the ratio with increase of the number of downsampling. This makes the low-resolution images obtained by downsampling have higher proportion in all downsampled images. The low-resolution images usually contain much global information. Therefore, it can help the model to learn more global feature information from downsampled images. Secondly, the attention mechanism is introduced to the generative network to increase the weight of effective image information. This can make the network learn more local details. Besides, in order to make the output image more natural, the TVLoss function is introduced to the loss function of SinGAN, to reduce the difference between adjacent pixels and smear phenomenon for the output image. A large number of experimental results show that our proposed model has better performance than other methods in generating random samples with fixed size and arbitrary size, image harmonization and editing.

Purpose: This study aimed to investigate the effects of an advanced practice nurse-led psychoeducational program on distress, anxiety, depression, coping with cancer (CWC), health promotion behavior (HPB), and quality of life (QOL) among colorectal cancer survivors. Methods: This study was designed as a quasi-experimental study with a non-equivalent control group pretest-posttest. The participants were survivors of colorectal cancer who underwent follow-up care. There were 39 survivors: 19 in the experimental group and 20 in the control group. The experimental group performed a psychoeducational program for 120 minutes per session, once a week for a total of six weeks, while the control group received routine education and counseling. Distress, anxiety, depression, CWC, HPB, and QOL were investigated before, immediately after, and 4 weeks after the intervention. The data were analyzed with SPSS/WIN ver. 24.0, using repeated measures ANOVA. Results: There were significant interactions between time and group for distress and anxiety. In addition, CWC interacted with the total of CWC and interpersonal coping, and QOL interacted with the total of QOL and functional status. However, there were no significant differences in the depression or HPB scores. Conclusion: Based on the results of this study, we expect that this program can be used as an effective intervention for colorectal cancer survivors.

Purpose: This study was conducted to develop a respiratory nursing program using recorder playing for patients with asthma and to determine the effects of the program. Method: Participants were 26 patients with asthma (experimental group: 13, control group: 13). The experimental group participated in the respiratory nursing program for six months from April, to October, 2007. Content included playing a recorder, group education about asthma, and educational messages including cellular phone messages. The control group received usual care during the six months. Results: In this research the respiratory nursing program using recorders was developed in 3 stages: initial stage, advanced stage, and wrap up stage. Compared to the control group, fatigue status in the experimental group improved significantly as well as level of forced expiratory volume in 1 second. However significant differences were found in sleep status, mood, or quality of life. Conclusions: These results suggest that this respiratory nursing program for symptom management of patients with asthma led to improvements in self care activity. Nursing interventions are needed to maintain and further enhance the quality of life of these patients and the interventions should be implemented over a transition period.
