The rapid progress of social media allows more people to express their feelings and opinions online. Many data on social media contains people's emotional information, which can be used for people's psychological analysis and emotional calculation. This research is based on the simplified psychological scale algorithm of multi-theory integration. It aims to accurately analyze people's psychological emotion. According to the comparative analysis of algorithm performance, the results show that the highest recall rate of the algorithm in this study is 95%, while the highest recall rate of the item response theory algorithm and the social network analysis algorithm is 68% and 87%. The acceleration ratio and data volume of the research algorithm are analyzed. The results show that when 400,000 data are calculated in the Hadoop cluster and there are 8 nodes, the maximum acceleration ratio is 40%. When the data volume is 8GB, the maximum scale ratio of 8 nodes is 43%. Finally, we carried out an empirical analysis on the model that compute the population's psychological and emotional conditions. During the analysis, the psychological simplification scale algorithm was adopted and multiple theories were taken into account. Then, we collected negative comments and expressions about Japan's discharge of radioactive water in microblog and compared them with the trend derived by the model. The results were consistent. Therefore, this research model has achieved good results in the emotion classification of microblog comments.

The study was conducted to investigate the effect of particle size on the physicochemical properties of egg yolk-rice porridge. The pH of egg yolk-rice porridge was decreased when compared to that of the control, while the lightness and yellowness was increased as the rice particle size increased. The viscosity of whole particle egg yolk porridge was highest among the three porridges at $40^{\circ}C$. The protein content of the egg yolk-rice porridge was increased three-fold, when compared to that of the rice porridges. The total amino acid content of egg yolk-rice porridge was 1,500.6 mg/100 g, while that of rice was 1,147.5 mg/100 g. The Lys and Thr content of the amino acid content of egg yolk-rice porridge were also increased. Sensory evaluation results revealed that the half particle size rice egg yolk-rice porridge had the highest scores in color, taste and over-all preference. Based on these results, the half particle size egg yolk-porridge had good quality with respect to both the physicochemical and nutritional properties.

This study is to compare the quality of child care centers in Sweden and Korea and the mothers' satisfaction of each center. In this study, the quality of 27 preschools in Sweden and 24 child care centers was evaluated by external evaluator using the Early Childhood Environment Rating Scale (ECERS). A total of 436 Korean mothers and 197 Swedish mothers responded to the questionnaire regarding their satisfaction of their child's attending child care centers. The results show that the quality of Swedish preschool was significantly higher than Korean child care centers. The quality of Swedish preschools tended to be good whereas the quality of Korean child care centers was somewhat minimal. Specifically, the category of 'Furnishings and display for children' was the highest score in Swedish preschool, however, the category of 'Adult needs' was the highest score in Korean child care centers. The mothers' satisfaction of the centers was significantly different between two countries. The Swedish mothers were highly satisfied with the close location of preschool but Korean mothers were highly satisfied with the teachers of child care centers. However, both mothers in two countries were less likely satisfied with the facility equipments. The results were discussed in terms of cultural and child care program differences further.

The aim of this study was to investigate the effects of artificial light sources on the germination and seedling vigor of lettuce, aiming to identify the optimal artificial light source for producing high-quality seedlings. Lettuce cultivar of 'Tomalin' and 'Seonpunggold' exhibited the highest seed emergence in the Metal halide(MH) lamp and High-pressure sodium(HPS) lamp treatment group, while the emergence rate parameter, T50, was the fastest in the HPS lamp treatment group. Both cultivars showed good growth characteristics such as number of leaves, root length, and stem diameter under RGB-LED, and their seedling vigor was excellent as well. The plant height was smallest in the Red + Green + Blue LED treatment, but the leaves were round and thick, resulting in higher biomass and dry weight. Single light sources of Red LED and Blue LED led to reduced growth compared with that under the mixed light treatments. Chlorophyll content in lettuce varied with the type of artificial light, with both cultivars exhibiting the highest chlorophyll content in the Red + Green + Blue LED treatment. The most suitable artificial light for lettuce seedling growth was the Red + Green + Blue LED treatment.

Unlike synthetic dyes, natural dyes do not affect the human body or create atmosphere pollution that are also mothproof, antibiotic and sterilized. This study examined the changes in dye adsorption properties according to mordant types and mordanting method to qualify trends using sage and rosemary extracts. Dyeability of sage extract is often similar to rosemary extract regardless of dyeing conditions. Dyeing properties of herb colorants on cotton, silk and wool fiber and effect of dyeing conditions on dye uptake were also compared. Dyed fabric showed a yellowish color and the dyeing affinity was somewhat good with rosemary extract. The surface color of the dyed fabrics was darkened by mordant treatment. The K/S value of herb colorants of protein fiber was higher than cellulose fiber. The concentration of mordant having the highest dyeing affinity was different from the mordant type. Regardless of the type of fiber, the K/S value of premordanting was the highest in mordanting method, and the K/S value of simultaneous mordanting indicated no noticeable mordant effect. The fastness of washing of silk fabric was reduced the most by mordant treatment. The lightfastness was reduced in Al mordant treatment regardless of the type of fiber. The lightfastness of wool increased somewhat by mordant treatment.

A sample of Italian manufacturing companies was selected in order to verify the abilities and effects (relationships) of the management factors human resources, leadership and strategic planning on company performance. The Partial Least Squares (PLS) estimation method was used for analyzing the data collected, where the relationships between the management factors and performance were formalized by a Structural Equation Model (SEM). The analysis of the survey data showed unexpected result regarding the non significant direct relationship between Leadership and Performance. The effect of Leadership is obtained by an indirect relationship through Human Resources. The combination of Leadership and Human Resources has hence been identified as the management factors which have the highest impact on the performance of Italian industrial companies. Another interesting and unexpected result was that there was no significant impact of Strategic Planning on Performance. It seems that the leaders of Italian industrial companies have not understood that good strategic planning is a necessary condition for achieving excellence. So another improvement area is in fact Strategic Planning. This area should have the highest priority of any top management team and the focus should include how to establish a strong relationship between strategic planning and performance. No correlation between strategic planning and performance is a strong indication that something is wrong. It is not enough that Leadership is doing Strategic Planning-Leadership is also about studying and follow up on results in order to assure impacts on performance. This link seems to be missing in Italian industrial companies.
