  • This study aimed to address the increasing demand for technologies preventing mushroom fly damage. By monitoring the annual occurrence patterns of pests over several years and accumulating data, we conducted an analysis to evaluate the efficacy of preventive measures applied before the surge in mushroom fly infestation, typically observed in May. For preemptive control, physical measures involved installing air curtains at cultivation facility entrances and placing sticky traps and insect traps around entry points to block external entry and reduce internal insect density. Additionally, we applied an organic agricultural material, Dalmatian chrysanthemum extract, weekly alongside chemical control measures. To assess the reduction in mushroom fly populations, yellow sticky traps (15×25 cm) were placed at three locations within the mushroom cultivation facility, and the occurrence patterns before and after implementing preventive measures were compared. Compared to conventional practices, the application of preventive techniques resulted in a significant reduction, with a 60% decrease from 15 levels of mushroom flies/m2 to 6 levels of mushroom flies/m2 in May and a 40% decrease from 10 levels of mushroom flies/m2 to 6 levels of mushroom flies/m2 in June. While achieving over 50% efficacy during the peak mushroom fly season with preventive measures, we identified complementary actions such as blocking external sources (gaps in cultivation facility doors) and maintaining cleanliness around cultivation facilities (proper disposal of spent substrate) for further improvement. Comprehensive analysis and safety studies, including correlation analysis with contaminants and pathogens, are recommended to ensure the widespread adoption of mushroom fly preventive techniques for safe and stable mushroom production in the agricultural sector.

  • We have studied the formation of Co/Ti bilayer silicide with low resistivity and good thermal stability on the heavily boron doped $\textrm{p}^{+}$-Si region. In this paper, Co/Ti bilayer silicides were fabricated by depositing Co($150\AA$)/Ti($50\AA$) films on the clean $\textrm{p}^{+}$-Si substrates in an E-beam evaporator and performing the two step RTA process (first annealing: 650$50^{\circ}C$/20sec, second annealing: $800^{\circ}C$/20sec) in a $N_2$ambient with the pressure of $\textrm{10}^{-1}$atm. Co/Ti bilayer silicides obtained from our experiments exhibited the low resistivity of about $18\mu\Omega$-cm and the uniform thickness of about $500\AA$ without change of sheet resistance and agglomeration under the long post0annealing time up to $1000^{\circ}C$.

  • Rearing knowledge is a significant factor of relevance for rearing practice, and assessment of rearing knowledge and practice is important for infant parents. The author adopted the Child Rearing Knowledge Scale (CRKS) and Child Rearing Practice Scale (CRPS) that were developed and validated by Saramma & Thomas. According to the international linguistic validation process, pilot testing was done based on 20 infant's mothers in one Oketani massage center and one public health center. Descriptive statistic methods and Wilcoxon Rank Sum Test were employed to evaluate the level and compare the mean score according to general characteristics of subjects of the tools. Reliability and validity were tested by Cronbach's alpha and Spearman Correlations. The mean age of the subjects was 33.94 (${\pm}2.99$) years and the mean age of babies was 3.35 (${\pm}0.58$) months. The understanding level of the Korean version of the CRKS and CRPS was 1.80 (${\pm}0.65$) and 1.33 (${\pm}0.54$), respectively. In addition, the CRKS and CRPS were relatively easy to use. The mean score of the CRKS was 22.50 (${\pm}4.89$), which was a moderate score, while the mean score of the CRPS was 30.75 (${\pm}2.04$), which was high. The Cronbach's alpha values of the CRPS were as follows: feeding, 0.71; growth and development, 0.64; cleaning and protection 0.68; infant stimulation, 0.77. There was a significant correlation between infant stimulation of the CRPS and growth and development of the CRKS (r=0.530, p=0.016). The CRKS score of medical staff was significantly higher than that of non-medical staff (p=0.04). The CRKS and CRPS are expected to be used in clinical or community care practice as easy-to-use tools that are easy to respond to.

  • Today's fast-paced world is becoming increasingly characterized by technology-facilitated transactions. Growing numbers of customers interact with technology to create service outcomes instead of interacting with a service firm employee. Self-service technologies provide technological interfaces that enable customers to produce a service independent of direct service employee involvement. To investigate on the customer satisfaction with self-technological based product design in Subway. I used the critical incident technique developed by Flanagan(1954) with quantitative measures of attributions. In this research, it results that customers are considered more important the value of technological-function and easy to use than the aspect of automated machine. It is likely that the technological aspect of many self-service options has a unique influence on customer perceptions of self-service encounters. Also, Research has shown that customer's needs are defined as situations in which external environmental factors add a sense of urgency to the transaction and saved time. On the other hand, customers realize that their favorable image of self-technological based product follows as ; first, customers prefer to the simple & modern image on the aspect of product design, secondly, customers prefer to the hitech-functional image to do its job fast in a short time by automated technology on the aspect of functional service, thirdly, customers prefer to the comfortable and sanitary image to be suitable for the underground circumstance.

  • Common mushroom production per area has been decreased and are up to less than 50% of the 1980 production. To determine the main reasons for the decrement, we performed this study. Two main reasons, which are mushroom disease and the low compost quality because of mechanized compost making, were assessed. In mechanized mushroom farms, nitrogen concentration in compost was lower than recommended and total compost quantity was about 100-150 $kg/3.3m^2$, which was also lower than usual. Our study revealed that higher nitrogen concentration (about 1.5%) in compost gave better production. Also, use of large amount of compost appeared to increase the mushroom production, although more insects and disease problems were observed. The relationships between the presences of microorganisms and occurrence of diseases were assessed by monitoring the microorganism densities near the mushroom farms. Higher number of microorganisms were observed near the mushroom farm area, compared to control region, Daechon beach. Most contaminating molds were found in the circulating fans, tunnel and culture room floor. The bacterial isolates were collected from the air in mushroom culture room and killed with 0.005% Benzalkonium solution, indicating treatment of Benzalkonium are the effective methods to sanitize the mushroom culture room.

  • This study examines the effects of reading and story sharing through fairy tales on young children's character development in their role play using natural materials. To achieve this, 40 5-year-old children at early childhood educational institutes in Daejeon were tested 16 times for 8 weeks. The results were as follows. First, their role plays using natural objects through reading and talking had a positive effect on their personality cultivation. Second, there was no experimental difference in their prudence and filial piety of basic behavioral items, but their cleanliness and patience were proven effective in the experiment. Third, all their justice, conscience and service indicating their sociality-related friendship, kindness, gentleness and morality were proven effective in the experiment, which their role plays using natural objects through reading and story sharing through fairy tales had an educational effect on improving their sociality and morality through peer interaction. This suggests that their mind to improve social virtues with an exchange of emotions, particularly, treat natural role play in a friendly way, their public promises to cherish life, and their ethical virtues to obey the rules in the process of consideration, appreciation, understanding and help through mutual communication and cooperation in forest experience activities are very effective from an educational perspective.
