The objective of this study is to induce the importance of manners through the relation between the implementation of manners and degree of life satisfaction in adolescents and to examine positive variants that can enhance degree of life satisfaction A total of 413 questionnaires were used as the final data for this study. The results of the study are as follows. 1. The implementation of manners in adolescents was just above the median. In particular, the lowest sector was in public manners and communication manners requiring intensive activation measures. The variables influencing the results were the score, internal-external control, perceptiveness to the importance of propriety 2. On the level of satisfaction with life as a general, the study showed reasonable standards. The variables influencing the results were the score, internal-external control, gender-role attitudes, perceptiveness to the importance of propriety. Also, considering that implementation of manners contributed to enhancing the level of satisfaction, the establishment of a healthy manners culture of adolescents in required.

The purpose of this study was to identify factors associated with sanitation and cleanliness regarding the importance of family restaurant employees in the Ulsan and Busan areas. Accordingly, this study conducted a suey questionnaire consisting of 28 measures of food-service as well as major subject descriptors. From the results, the frequency, descriptive, factor, correspondence analysis, major findings and marketing implications could be summarized as follows: First, 6 factors were extracted: cooking and control factor, food and tableware handling factor, personal cleanliness condition factor, purchase and receiving factor, unit food material store factor and Kitchen utensil sanitation factor. KMO and Bartlett' stest statistics showed that the data fitted the factor analysis well. Results of factor analysis, average variance extracted estimates and shared variance showed that the convergent and discriminant validity of 6 factors are supported and Cronbach's alpha showed that the internal consistency of the 6 factors was supported. Second, correspondence analysis indicated that statistically significant relationships existed between some of the family restaurant employee sanitation and cleanliness factors and the family restaurant enterprise.

Recent analysis results with realistic assumptions provide the variability of operator allowable time for the initiation of aggressive cooldown under small break loss of coolant accident or steam generator tube rupture with total failure of high pressure safety injection. We investigated how plant risk may vary depending on the variability of operators' failure probability of timely initiation of aggressive cooldown. Using a probabilistic safety assessment model of a nuclear power plant, we showed that plant risks had a linear relation with the failure probability of aggressive cooldown and could be reduced by up to 10% as aggressive cooldown is more reliably performed. For individual accident management, we found that core damage potential could be gradually reduced by up to 40.49% and 63.84% after a small break loss of coolant accident or a steam generator tube rupture, respectively. Based on the importance of timely initiation of aggressive cooldown by main control room operators within the success criteria, implications for improvement of emergency operating procedures are discussed. We recommend conducting further detailed analyses of aggressive cooldown, commensurate with its importance in reducing risks in nuclear power plants.

The rate of accidents in the domestic construction industry is on the rise, which is 1.9 times higher than in other industries in 2018. The increasing trend of construction accidents shows the limitation of the current construction safety management system, and enhancement of the effect to prevent accidents in the construction industry is required through carious measures for improvement. This paper aims to increase the efficiency of safety management in the construction industry by deriving standard safety management tasks to prevent accidents in the construction industry and deriving document simplification and importance based on IPA analysis results.

In the era of the pandemic, the importance of a wireless LAN environment has become increasingly important, especially as the era of smart working and non-face-to-face education has become a universal and daily routine. Smartphones, tablets, laptops, PCs, smart watches, and wearable devices, collective referred to as wireless terminals, can be accessed anytime and anywhere through the internet, allowing for consistent and constant access to offices, factories, warehouses, shopping malls, railways, hotels, hospitals, schools, logistics centers, airports, exhibition halls, etc. This sort of access is currently being used in roads, parks, traditional markets, and ports. Since the release of the IEEE 802.11 Legacy Standard in 1997, Wi-Fi technology has been continuously supplemented and revised, and the standard has been continuously developed. In the era of smart working, the importance of efficient wireless deployment and scientific design has become more important. The importance of wireless in the smart factory, in the metaverse era, in the era of pursuing work and life that transcend time and space by using AR, VR, MR, and XR, it is more urgent to solve the shadow area of Wi-Fi. Through this study, we intend to verify the wireless failure problem of the xr training center and suggest improvement measures.

This exploratory study examines critical quality factors of store that can give access to credit card. The procedures of developing instrument is followed by recommendations on the developing measures of marketing constructs. The results shows that service quality of store available for credit card is divided four dimensions(personal service, payment-approving service, information-providing service, problem responsiveness service). These dimensions and scales are verified through the assessment of reliability and validity. Finally, the importance of personal service is showed to be different across types of industry.

The current use of leading causes of death is an outmoded, misleading counterproductive measure of importance of disease. The 'new' concept of productive years of life discounted to the future and combined with morbidity, disability, and direct cost measures will give a much more meaningful, useful measure of the magnitude of disease problems in Korea. I am looking forward to seeing refinements and improvements on this technique carried out by some readers of this paper.

The overall performance of BISDN depends significantly on the interconnection network or the switch fabric. Hence, it is extremely important to evaluate the performance of the network or the fabric. The well developed performance models also provide insight into the factors that determine design tradeoffs as well as quantitative estimates of their importance. The objective of this paper is to investigate and critically compare all the developed performance analysis models of FPS according to internal switch fabric structure, traffic assumptions, performance measures, methodologies, etc. FPSs are described according to their internal fabric structure. Brief history of FPS performance analysis is mentioned and performance analysis modeling is discussed.

This paper analyzes the customer behavior on high efficiency motor programs from three angles, that is, rebates, electricity rates and the cost of measures. After deregulation, the importance of high efficiency DSM programs has been more and more increased. Especially, the motor program is one of the most high efficiency DSM program, so it Is needed the policy to promote the motor programs diffusion.
